`Services offered to higher layers
`
`Transport channels
`4.1
`Transport channels are services offered by Layer 1 to the higher layers. General concepts about transport channels are
`described in [12].
`
`A transport channel is defined by how and with what characteristics data is transferred over the air interface. A general
`classification of transport channels is into two groups:
`
`- Dedicated channels, using inherent addressing of UE;
`
`- Common channels, using explicit addressing of UE if addressing is needed.
`
`Dedicated transport channels
`4.1.1
`There exists two types of dedicated transport channel, the Dedicated Channel (DCH) and the Enhanced Dedicated
`Channel (E-DCH).
`
`DCH - Dedicated Channel
`4.1.1.1
`The Dedicated Channel (DCH) is a downlink or uplink transport channel. The DCH is transmitted over the entire cell or
`over only a part of the cell using e.g. beam-forming antennas.
`
`E-DCH – Enhanced Dedicated Channel
`4.1.1.2
`The Enhanced Dedicated Channel (E-DCH) is an uplink transport channel.
`
`Common transport channels
`4.1.2
`There are seven types of common transport channels: BCH, FACH, PCH, RACH, and HS-DSCH.
`
`BCH - Broadcast Channel
`4.1.2.1
`The Broadcast Channel (BCH) is a downlink transport channel that is used to broadcast system- and cell-specific
`information. The BCH is always transmitted over the entire cell and has a single transport format.
`
`FACH - Forward Access Channel
`4.1.2.2
`The Forward Access Channel (FACH) is a downlink transport channel. The FACH is transmitted over the entire cell.
`The FACH can be transmitted using power setting described in [16].
`
`PCH - Paging Channel
`4.1.2.3
`The Paging Channel (PCH) is a downlink transport channel. The PCH is always transmitted over the entire cell. The
`transmission of the PCH is associated with the transmission of physical-layer generated Paging Indicators, to support
`efficient sleep-mode procedures.

`
`3GPP TS 25.211 V7.4.0 (2007-11)
`
`RACH - Random Access Channel
`4.1.2.4
`The Random Access Channel (RACH) is an uplink transport channel. The RACH is always received from the entire
`cell. The RACH is characterized by a collision risk and by being transmitted using open loop power control.
`
`4.1.2.5
`
`4.1.2.6
`

`
`Void
`
`HS-DSCH – High Speed Downlink Shared Channel
`4.1.2.7
`The High Speed Downlink Shared Channel is a downlink transport channel shared by several UEs. The HS-DSCH can
`be associated with one downlink DPCH, and one or several Shared Control Channels (HS-SCCH). The HS-DSCH is
`transmitted over the entire cell or over only part of the cell using e.g. beam-forming antennas.
`
`Indicators
`4.2
`Indicators are means of fast low-level signalling entities which are transmitted without using information blocks sent
`over transport channels. The meaning of indicators is specific to the type of indicator.
`
`The indicators defined in the current version of the specifications are: Acquisition Indicator (AI), Page Indicator (PI)
`and MBMS Notification Indicator (NI).
`
`Indicators may be either boolean (two-valued) or three-valued. Their mapping to indicator channels is channel specific.
`
`Indicators are transmitted on those physical channels that are indicator channels (ICH).
`
`Physical channels and physical signals
`5
`Physical channels are defined by a specific carrier frequency, scrambling code, channelization code (optional), time
`start & stop (giving a duration) and, on the uplink, relative phase (0 or /2). The downlink E-HICH and E-RGCH are
`each further defined by a specific orthogonal signature sequence. Scrambling and channelization codes are specified in
`[4]. Time durations are defined by start and stop instants, measured in integer multiples of chips. Suitable multiples of
`chips also used in specification are:
`
`Radio frame:
`
`Slot:
`
`Sub-frame:
`
`A radio frame is a processing duration which consists of 15 slots. The length of a radio
`frame corresponds to 38400 chips.
`
`A slot is a duration which consists of fields containing bits. The length of a slot corresponds
`to 2560 chips.
`
`A sub-frame is the basic time interval for E-DCH and HS-DSCH transmission and E-DCH
`and HS-DSCH-related signalling at the physical layer. The length of a sub-frame
`corresponds to 3 slots (7680 chips).
`
`The default time duration for a physical channel is continuous from the instant when it is started to the instant when it is
`stopped. Physical channels that are not continuous will be explicitly described.
`
`Transport channels are described (in more abstract higher layer models of the physical layer) as being capable of being
`mapped to physical channels. Within the physical layer itself the exact mapping is from a composite coded transport
`channel (CCTrCH) to the data part of a physical channel. In addition to data parts there also exist channel control parts
`and physical signals.
`
`Physical signals
`5.1
`Physical signals are entities with the same basic on-air attributes as physical channels but do not have transport channels
`or indicators mapped to them. Physical signals may be associated with physical channels in order to support the
`function of physical channels.

`
`Uplink physical channels
`
`Dedicated uplink physical channels
`5.2.1
`There are five types of uplink dedicated physical channels, the uplink Dedicated Physical Data Channel (uplink
`DPDCH), the uplink Dedicated Physical Control Channel (uplink DPCCH), the uplink E-DCH Dedicated Physical Data
`Channel (uplink E-DPDCH), the uplink E-DCH Dedicated Physical Control Channel (uplink E-DPCCH) and the uplink
`Dedicated Control Channel associated with HS-DSCH transmission (uplink HS-DPCCH).
`
`The DPDCH, the DPCCH, the E-DPDCH, the E-DPCCH and the HS-DPCCH are I/Q code multiplexed (see [4]).
`
`DPCCH and DPDCH
`5.2.1.1
`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 Layer 1 control information consists
`of known pilot bits to support channel estimation for coherent detection, transmit power-control (TPC) commands,
`feedback information (FBI), and an optional transport-format combination indicator (TFCI). The transport-format
`combination indicator informs the receiver about the instantaneous transport format combination of the transport
`channels mapped to the simultaneously transmitted uplink DPDCH radio frame. There is one and only one uplink
`DPCCH on each radio link.
`
`Figure 1 shows the frame structure of the uplink DPDCH and the uplink DPCCH. Each radio frame of length 10 ms is
`split into 5 subframes, each of 3 slots, each of length Tslot = 2560 chips, corresponding to one power-control period. The
`DPDCH and DPCCH are always frame aligned with each other.

`
`
`
`The parameter k in figure 1 determines the number of bits per uplink DPDCH slot. It is related to the spreading factor
`SF of the DPDCH as SF = 256/2k. The DPDCH spreading factor may range from 256 down to 4. The spreading factor
`of the uplink DPCCH is always equal to 256, i.e. there are 10 bits per uplink DPCCH slot.
`
`The exact number of bits of the uplink DPDCH and the different uplink DPCCH fields (Npilot, NTFCI, NFBI, and NTPC) is
`given by table 1 and table 2. What slot format to use is configured by higher layers and can also be reconfigured by
`higher layers.

`
`The channel bit and symbol rates given in table 1 and table 2 are the rates immediately before spreading. The pilot
`patterns are given in table 3 and table 4, the TPC bit pattern is given in table 5.
`
`The FBI bits are used to support techniques requiring feedback from the UE to the UTRAN Access Point for operation
`of closed loop mode transmit diversity. The use of the FBI bits is described in detail in [5].

`
`There are two types of uplink dedicated physical channels; those that include TFCI (e.g. for several simultaneous
`services) and those that do not include TFCI (e.g. for fixed-rate services). These types are reflected by the duplicated
`rows of table 2. It is the UTRAN that determines if a TFCI should be transmitted and it is mandatory for all UEs to
`support the use of TFCI in the uplink. The mapping of TFCI bits onto slots is described in [3].
`
`In compressed mode, DPCCH slot formats with TFCI fields are changed. There are two possible compressed slot
`formats for each normal slot format. They are labelled A and B and the selection between them is dependent on the
`number of slots that are transmitted in each frame in compressed mode.
`
`If UL_DTX_Active is TRUE (see [5]), the number of transmitted slots per radio frame may be less than the number
`shown in Table 2.

`The pilot bit patterns are described in table 3 and table 4. The shadowed column part of pilot bit pattern is defined as
`FSW and FSWs can be used to confirm frame synchronization. (The value of the pilot bit pattern other than FSWs shall
`be "1".)
