4 Frame structure Throughout this specification, unless otherwise noted, the size of various fields in the time domain is expressed as a number of time units ( )2048150001s ×=T seconds.
Downlink and uplink transmissions are organized into radio frames with ms 10307200 sf =×= TT duration. Two radio
frame structures are supported:
- Type 1, applicable to both FDD and TDD,
- Type 2, applicable to TDD only.
4.1 Frame structure type 1 Frame structure type 1 is applicable to both full duplex and half duplex FDD and to TDD. Each radio frame is
ms 10307200 sf =×= TT long and consists of 20 slots of length ms 5.0T15360 sslot =×=T , numbered from 0 to 19. A
subframe is defined as two consecutive slots where subframe i consists of slots i2 and 12 +i .
For FDD, 10 subframes are available for downlink transmission and 10 subframes are available for uplink transmissions in each 10 ms interval. Uplink and downlink transmissions are separated in the frequency domain.
For TDD, a subframe is either allocated to downlink or uplink transmission. Subframe 0 and subframe 5 are always allocated for downlink transmission.

3GPP
3GPP TS 36.211 V8.0.0 (2007-09)9Release 8
4.2 Frame structure type 2 Frame structure type 2 is only applicable to TDD. Each radio frame consists of two half-frames of length
ms 5153600 sf =×= TT each. The structure of each half-frame in a radio frame is identical. Each half-frame consists of
seven slots, numbered from 0 to 6, and three special fields, DwPTS, GP, and UpPTS. A subframe is defined as one slot where subframe i consists of slot i .
Subframe 0 and DwPTS are always reserved for downlink transmission. UpPTS and subframe 1 are always reserved for uplink transmission.

5 Uplink
5.1 Overview The smallest resource unit for uplink transmissions is denoted a resource element and is defined in section 5.2.2.
5.1.1 Physical channels
An uplink physical channel corresponds to a set of resource elements carrying information originating from higher layers and is the interface defined between 36.212 and 36.211. The following uplink physical channels are defined:
- Physical Uplink Shared Channel, PUSCH
- Physical Uplink Control Channel, PUCCH
- Physical Random Access Channel, PRACH
5.1.2 Physical signals
An uplink physical signal is used by the physical layer but does not carry information originating from higher layers. The following uplink physical signals are defined:
- reference signal

5.2 Slot structure and physical resources
5.2.1 Resource grid
The transmitted signal in each slot is described by a resource grid of RBsc
ULRB NN subcarriers and UL
symbN SC-FDMA
symbols. The resource grid is illustrated in Figure 5.2.1-1. The quantity ULRBN depends on the uplink transmission
bandwidth configured in the cell and shall fulfil
1106 ULRB ≤≤ N
The set of allowed values for ULRBN is given by [6].
The number of SC-FDMA symbols in a slot depends on the cyclic prefix length configured by higher layers and is given in Table 5.2.3-1.

5.2.2 Resource elements
Each element in the resource grid is called a resource element and is uniquely defined by the index pair ( )lk, in a slot
where 1,...,0 RBsc
ULRB −= NNk and 1,...,0 UL
symb −= Nl are the indices in the frequency and time domain, respectively.
Resource element ( )lk, corresponds to the complex value lka , . Quantities lka , corresponding to resource elements not
used for transmission of a physical channel or a physical signal in a slot shall be set to zero.
5.2.3 Resource blocks
A resource block is defined as ULsymbN consecutive SC-FDMA symbols in the time domain and RB
scN consecutive
subcarriers in the frequency domain, where ULsymbN and RB
scN are given by Table 5.2.3-1. A resource block in the uplink
thus consists of RBsc
ULsymb NN × resource elements, corresponding to one slot in the time domain and 180 kHz in the
frequency domain.

5.3 Physical uplink shared channel The baseband signal representing the physical uplink shared channel is defined in terms of the following steps:
- scrambling
- modulation of scrambled bits to generate complex-valued symbols
- transform precoding to generate complex-valued modulation symbols
- mapping of complex-valued modulation symbols to resource elements
- generation of complex-valued time-domain SC-FDMA signal for each antenna port

5.3.1 Scrambling
If scrambling is configured, the block of bits )1(),...,0( bit −Mbb , where bitM is the number of bits transmitted on the
physical uplink shared channel in one subframe, shall be scrambled with a UE-specific scrambling sequence prior to modulation, resulting in a block of scrambled bits )1(),...,0( bit −Mcc .

PRACH configuration Subframes
For frame structure type 2, the start of the random access burst depends on the burst format configured. For burst format 0, the burst shall start s5120T before the end of the UpPTS at the UE. For burst format 1, the start of the random access
burst shall be aligned with the start of an uplink subframe.
In the frequency domain, the random access burst occupies a bandwidth corresponding to 6 resource blocks for both frame structures.

6 Downlink
6.1 Overview The smallest time-frequency unit for downlink transmission is denoted a resource element and is defined in Section 6.2.2.
6.1.1 Physical channels
A downlink physical channel corresponds to a set of resource elements carrying information originating from higher layers and is the interface defined between 36.212 and 36.211. The following downlink physical channels are defined:
- Physical Downlink Shared Channel, PDSCH
- Physical Broadcast Channel, PBCH
- Physical Multicast Channel, PMCH
- Physical Control Format Indicator Channel, PCFICH
- Physical Downlink Control Channel, PDCCH
- Physical Hybrid ARQ Indicator Channel, PHICH

3GPP TS 36.211 V8.0.0 (2007-09)21Release 8
6.1.2 Physical signals
A downlink signal corresponds to a set of resource elements used by the physical layer but does not carry information originating from higher layers. The following downlink physical signals are defined:
- reference signal
- synchronization signal
6.2 Slot structure and physical resource elements
6.2.1 Resource grid
The transmitted signal in each slot is described by a resource grid of RBsc
DLRB NN subcarriers and DL
symbN OFDM symbols.
The resource grid structure is illustrated in Figure 6.2.2-1. The quantity DLRBN depends on the downlink transmission
bandwidth configured in the cell and shall fulfil
1106 DLRB ≤≤ N
The set of allowed values for DLRBN is given by [6]. The number of OFDM symbols in a slot depends on the cyclic
prefix length and subcarrier spacing configured and is given in Table 6.2.3-1.
In case of multi-antenna transmission, there is one resource grid defined per antenna port. An antenna port is defined by its associated reference signal. The set of antenna ports supported depends on the reference signal configuration in the cell:
- Cell-specific reference signals, associated with non-MBSFN transmission, support a configuration of one, two, or four antenna ports, i.e. the antenna port number p shall fulfil 0=p , { }1,0∈p , and { }3,2,1,0∈p ,
respectively.
- MBSFN reference signals, associated with MBSFN transmission, are transmitted on antenna port 4=p .
- UE-specific reference signals, supported in frame structure type 2 only, are transmitted on antenna port 5=p .
6.2.2 Resource elements
Each element in the resource grid for antenna port p is called a resource element and is uniquely identified by the
index pair ( )lk, in a slot where 1,...,0 RBsc
DLRB −= NNk and 1,...,0 DL
symb −= Nl are the indices in the frequency and time
domains, respectively. Resource element ( )lk, on antenna port p corresponds to the complex value )(,plka . When there
is no risk for confusion, or no particular antenna port is specified, the index p may be dropped.

A physical resource block is defined as DLsymbN consecutive OFDM symbols in the time domain and RB
scN consecutive
subcarriers in the frequency domain, where DLsymbN and RB
scN are given by Table 6.2.3-1. A physical resource block thus
consists of RBsc

domain.

A virtual resource block is of the same size as a physical resource block. Two types of virtual resource blocks are defined:
- virtual resource blocks of distributed type
- virtual resource blocks of localized type
Virtual resource blocks are mapped to physical resource blocks with the mapping depending on the diversity order configured.
For second-order diversity, one virtual resource block is mapped to one physical resource block. The virtual-to-physical resource block mapping is different in the two slots of a subframe.

6.2.4 Guard Period for TDD Operation
For TDD operation with frame structure type 1, the last GPN downlink OFDM symbol(s) in a subframe immediately
preceding a downlink-to-uplink switch point can be reserved for guard time and consequently not transmitted. The supported guard periods are listed in Table 6.2.4-1.

6.3 General structure for downlink physical channels This section describes a general structure, applicable to more than one physical channel.
The baseband signal representing a downlink physical channel is defined in terms of the following steps:
- scrambling of coded bits in each of the code words to be transmitted on a physical channel
- modulation of scrambled bits to generate complex-valued modulation symbols
- mapping of the complex-valued modulation symbols onto one or several transmission layers
- precoding of the complex-valued modulation symbols on each layer for transmission on the antenna ports
- mapping of complex-valued modulation symbols for each antenna port to resource elements
- generation of complex-valued time-domain OFDM signal for each antenna port

In case multiple PHICHes are mapped to the same resource elements, these PHICHes shall be summed prior to the mapping. Higher layers can configure the PHICH to span the first or the first three OFDM symbols in a subframe. The value configured puts a lower limit on the size of the control region signalled by the PCFICH. If the PHICH is configured to span three OFDM symbols, there is one group of four resource elements in each of the three OFDM symbols.

- Cell-specific reference signals, associated with non-MBSFN transmission
- MBSFN reference signals, associated with MBSFN transmission
- UE-specific reference signals (supported in frame structure type 2 only)
There is one reference signal transmitted per downlink antenna port.
6.10.1 Cell-specific reference signals
Editor’s note: The reference signal description in this section is applicable to kHz 15=Δf only.
Cell-specific reference signals shall be transmitted in all downlink subframes in a cell supporting non-MBSFN transmission. In case the subframe is used for transmission with MBSFN, only the first two OFDM symbols in a subframe can be used for transmission of cell-specific reference symbols.
Cell-specific reference signals are transmitted on one or several of antenna ports 0 to 3.
6.10.1.1 Sequence generation
The generation of the two-dimensional reference signal sequence )( s, nr nm , where sn is the slot number within the radio
frame, depends on the cyclic prefix used.
For normal cyclic prefix, )( s, nr nm is generated as the symbol-by-symbol product )()( sPRS,
OS,s, nrrnr nmnmnm ⋅= of a two-
dimensional orthogonal sequence OS,nmr and a two-dimensional pseudo-random sequence )( s
PRS, nr nm . There are 3OS =N
different two-dimensional orthogonal sequences and 170PRS =N different two-dimensional pseudo-random sequences.
There is a one-to-one mapping between the three identities within the physical-layer cell identity group and the three two-dimensional orthogonal sequences such that orthogonal sequence }2,1,0{∈n corresponds to identity n within the
physical-layer cell identity group in Section 6.11.1.1.
For extended cyclic length, )( s, nr nm is generated from a two-dimensional pseudo-random sequence )( sPRS, nr nm . There is
a one-to-one mapping between the physical-layer cell identity and the 510PRS =N different two-dimensional pseudo-
random sequences.

UE-specific reference signals are supported for single-antenna-port transmission of PDSCH in frame structure type 2 only and are transmitted on antenna port 5.

6.10.3.1 Sequence generation
6.10.3.2 Mapping to resource elements
6.11 Synchronization signals There are 510 unique physical-layer cell identities. The physical-layer cell identities are grouped into 170 unique physical-layer cell-identity groups, each group containing three unique identities. The grouping is such that each physical-layer cell identity is part of one and only one physical-layer cell-identity group. A physical-layer cell identity is thus uniquely defined by a number in the range of 0 to 169, representing the physical-layer cell-identity group, and a number in the range of 0 to 2, representing the physical-layer identity within the physical-layer cell-identity group.
6.11.1 Primary synchronization signal
6.11.1.1 Sequence generation
The sequence used for the primary synchronization signal in a cell shall be selected from a set of three different sequences. There is a one-to-one mapping between the three physical-layer cell identities within the physical-layer cell-identity group and the three sequences used for the primary synchronization signal.
The sequence )(nd used for the primary synchronization signal is generated from a frequency-domain Zadoff-Chu
sequence according to

The mapping of the sequence to resource elements depends on the frame structure. The antenna port used for transmission of the primary synchronization signal is not specified.

6.11.2 Secondary synchronization signal
6.11.2.1 Sequence generation
The sequence used for the second synchronization signal is an interleaved concatenation of two length-31 binary
sequences obtained as cyclic shifts of a single length-31 M-sequence generated by 125 ++ xx . The concatenated sequence is scrambled with a scrambling sequence given by the primary synchronization signal.
6.11.2.2 Mapping to resource elements
The mapping of the sequence to resource elements depends on the frame structure. In a subframe, the same antenna port as for the primary synchronization signal shall be used for the secondary synchronization signal.
