2 Channel Introduction

Information between different layers or between equivalent entities at layer 1 is carried on

channels.

The following three types of channel are defined in UTRAN:

z Logical channel

Logical channels implement data transfer between layer 2 and the higher layer. Logicalchannels are mapped onto transport channels at the MAC layer, which is part of layer 2.

z Transport channel

Transport channels implement data transfer between layer 2 and layer 1. Transportchannels are mapped onto physical channels at layer 1.

z Physical channel

Physical channels implement data transfer on the radio interface between equivalent

layer 1 entities. The physical channels correspond to different radio frame types andcontents.

This document describes the three types of channel. Figure 2-1 shows the positions of the

three types of channel at the protocol layers.

3.1 Logical Channel

The MAC layer provides data transfer services on logical channels. A set of logical channel

types is defined for different kinds of data transfer as offered by MAC. Each logical channel

type is defined by what type of information is transferred.

Generally, logical channels are categorized into the following types:

z Control channel (for the transfer of control plane information)

z Traffic channel (for the transfer of user plane information)

Table 3-1 describes the logical channels supported by Huawei.

This channel is commonly used by the

RNC and UEs before the RRCconnection is set up or when a UE

accesses a new cell after cellreselection.

control information between a UE andthe network.

This channel is established through an

RRC connection setup procedure.

DCCH is associated with DTCH.

3.1.1 Logical Channel Priority

Logical channel priority is used to define the priority of each logical channel. It works when

more than one logical channel is mapped onto one transport channel or physical channel.

Typically, logical channel priorities need to be set for only DCCH and DTCH.



RAN




3-3

The logical channel priority is set based on the type of the logical channel and the service thatthe logical channel carries. Each service corresponds to a logical channel priority.

To improve the user experience, the logical channel priority is set according to the following

rule:

Signaling > CS service > PS interactive service> PS background service

The value of logical channel priority ranges from 1 to 8. The value 1 corresponds to the highest priority.

3.1.2 System Information Block and Default Value

This describes System Information Blocks (SIBs), which are carried on the BCCH. Thesystem information elements are broadcast in SIBs.

Overview of System Information Block

A system information block groups together system information elements of the same nature.

Different SIBs may have different characteristics, for example, repetition rate and therequirements on UEs to re-read the SIBs.

The system information is organized as a tree. A master information block gives referencesand scheduling information to a number of system information blocks in a cell. The system

information blocks contain the actual system information.

Scheduling of system information blocks is performed by the RRC layer in UTRAN. RRCcan calculate the repetition period and position of each SIB segment for every SIB

automatically based on its importance.

Figure 3-1 shows an example of SIB scheduling result. In Figure 3-1, MIB (Master information block) is sent firstly, and SB1 is sent secondly.

3.2 Transport Channel

A transport channel is defined by how and with what characteristics data is transferred over

the air interface.

Generally, transport channels are categorized into the following types:

z Common transport channel (where UE is addressed by the ID carried with the transport block)

z Dedicated transport channel (where UE is identified by the physical channel, for example, code and frequency)

Table 3-4 describes the transport channel supported by Huawei.

3.2.1 Non-HSPA Channel Transport Format

This describes the concepts related to non-HSPA channel transport formats.

To each transport channel, there is an associated transport format (for transport channels with

a fixed rate) or an associated transport format set (for transport channels with fast changing

rate).

A transport format is defined as a combination of encoding, bit rate, rate matching attributeand CRC size. A transport format set is a set of transport formats. For example, a variable-rate

DCH has a transport format set (one transport format for each rate), whereas a fixed-rate DCHhas a single transport format.

See definitions as follows:

z Transport block: This is the basic unit exchanged between layer 1 and MAC, for layer 1 processing.

z Transport block set: This is defined as a set of transport blocks, which are exchanged

between layer 1 and MAC at the same time instance using the same transport channel.

z Transport format: This is defined as a format offered by layer 1 to MAC (and the other way round) for the delivery of a transport block set during a Transmission Time Interval

(TTI) on a transport channel. The transport format consists of two parts: dynamic part

and semi-static part.− Attributes of the dynamic part are:

Transport block size

Number of transport blocks

− Attributes of the semi-static part are:

Transmission Time Interval

Channel code type

Coding rate

Rate matching attribute

CRC sizez Transport format combination: This is defined as an authorized combination of currently

valid transport formats that can be submitted simultaneously to layer 1 for transmissionon a Coded Composite Transport Channel (CCTrCH) of a UE.

Figure 3-2 shows an example where transport block sets, at certain time instances, are

exchanged between MAC and layer 1 through three parallel transport channels. Each transport block set consists of a number of transport blocks. The transmission time interval is the time

between consecutive deliveries of data between MAC and layer 1, is illustrated.



RAN

Figure 3-2 Exchange of data between MAC and layer 1

3.2.2 HSPA Channel Transport Format

This describes transport formats of the HS-DSCH and E-DCH.

Overview of HSPA Channel Transport Format

HS-DSCH and E-DCH transport formats have the following distinctive features:

z Only one transport block is sent during each TTI. The transport block size is determined by the resources available and the amount of data to be transmitted at each datatransmission.

z The rate matching attribute is not included. The channel code type is fixed to Turbo,and the CRC size is 24 bits.

HS-DSCH Transport Format

For the HS-DSCH, the TTI is fixed to 2 ms. The MAC-hs entity in the NodeB maintains aseries of Channel Quality Indicator (CQI) mapping tables which are based on the HSDPA UEcategories. The CQI mapping table includes the following contents that correspond to the CQI

value:

z Transport block size

z The number of HS-PDSCHs

z Modulation

z Reference power adjustment Δ

z The number of soft channel bits available in the virtual IR buffer (NIR )

z Redundancy and constellation version parameter (XRV)




RAN

Channel Description



Issue 02 (2008-07-30)

The values in the CQI mapping table are obtained from emulation tests.

The HS-DSCH chooses in real time the transport block size according to the CQI, the

available power and channel code resources, and the amount of data to be transmitted. This

scheme allows the transmission rate for the UE to be dynamically adjusted.

Table 3-5 is a typical CQI mapping table.

E-DCH Transport Format

For E-DCH, the TTI can be set to 2 ms or 10 ms. RRC can configure the MAC-e to use one of

two transport block size sets for each TTI duration. The normative description of the mapping

between the E-TFCI and the corresponding transport block size is provided by Table 3-6,Table 3-7, Table 3-8 and Table 3-9(from the 3GPP TS 25.321). The transport block size used

in each TTI is determined by:

z Power granted from the NodeB

z Maximum power capability of the UE

z Amount of data to be transmitted

3.3 Physical Channel

A physical channel is defined by a specific carrier frequency, scrambling code, channelization

code (optional), time duration, and, in the uplink, relative phase (0 or π/2).

Time duration is defined by start time and stop time, measured in integer multiples of chips.

Other multiples of chips used are as follows:

z Radio frame: One radio frame consists of 15 slots, corresponding to 38,400 chips.

z Slot: A slot consists of bit fields. One slot corresponds to 2,560 chips.

z Subframe: A subframe is the basic time interval for transmission of HS-DSCH data andrelated signaling at the physical layer. One subframe consists of 3 slots, corresponding to7,680 chips.

Transport channels are mapped onto physical channels. Within the physical layer, the exactmapping is from a Composite Coded Transport Channel (CCTrCH) to the data part of a

physical channel. In addition to the data part, there are also the channel control part and

physical signals.

Physical signals are entities with the same basic air interface attributes as the physical channel but do not have transport channels or indicators mapped onto them. Physical signals, such as

the PRACH preamble part, can be used to support the function of the physical channel.

Table 3-10 describes the physical channels supported by Huawei.

3.3.1 Non-HSPA Physical Channels

This describes the concepts related to Non-HSPA physical channels. For more details, refer to3GPP TS 25.211.

Dedicated Physical Channels (Uplink)

Dedicated uplink physical channels include uplink Dedicated Physical Data Channel

(DPDCH) and uplink Dedicated Physical Control Channel (DPCCH).

The uplink DPDCH is used to carry the DCH transport channel. There may be zero, one, or

several uplink DPDCHs on each radio link.

The uplink DPCCH is used to carry control information generated at layer 1. The informationconsists of known pilot bits to support channel estimation for coherent detection, transmit

power-control (TPC) commands, Feedback Information (FBI), and an optional TransportFormat Combination Indicator (TFCI). The TFCI informs the receiver of the instantaneous

transport format combination of the transport channels mapped onto the simultaneouslytransmitted uplink DPDCH radio frame. There is one and only one uplink DPCCH on each

radio link.

Figure 3-3 shows the frame structure of the uplink DPDCH and the uplink DPCCH. Each 10

ms frame is split into 15 slots, corresponding to one power control period. The DPDCH andDPCCH are always frame aligned with each other.

Figure 3-3 Frame structure of the uplink DPDCH/DPCCH

The parameter k in Figure 3-3 determines the number of bits per uplink DPDCH slot. The SFof the DPDCH is equal to 256/2

k . The DPDCH SF ranges from 256 down to 4. The SF of the

uplink DPCCH is always equal to 256, that is, each uplink DPCCH slot has 10 bits.

Dedicated Physical Channels (Downlink)

Dedicated data and control information are transmitted on the downlink DPCH in TDM mode.Dedicated data is generated at layer 2 or higher layers, and control information is generated at

layer 1. Therefore, the downlink DPCH can be regarded as a combination of downlink

DPDCH and downlink DPCCH in TDM mode.

Figure 3-4 shows the frame structure of the downlink DPCH. Each 10 ms frame is split into

15 slots, corresponding to one power control period.

The exact number of bits in different downlink DPCH fields (NPilot, NTPC, NTFCI, Ndata1 and Ndata2) corresponds to a specific slot format. The slot format to be used is configured by higher layers and can be reconfigured also by higher layers.

Fractional Dedicated Physical ChannelsWithin one F-DPCH, there is no dedicated data, and the control information is only the TPC

command that is generated at layer 1, without pilot bits or TFCI.

Figure 3-5 shows the frame structure of the F-DPCH. Each 10 ms frame is split into 15 slots,corresponding to one power control period. One UE uses only a tenth of a slot.
