`
`
`This paper outlines text proposal for the RAN] TR on HS—DSCH, section on Associated Downlink Signalling.
`Some specific topics clarified in the text proposal:
`-
`The basic physical-channel structure for the HS-D SCH related signalling consists of one to four Shared Control
`
`Channels and a downlink DPCH. Note that this is as seen from the U3) i.e. from a Node B point-of—View there
`may be more than four Shared Control Channels
`"he HI on the DL DPCH points at the Shared Control Channel. As the proposal is that the HI should anyway
`include on/off signalling (DTX), the additional pointer signalling is basically for free, compare Figure 3.
`"he information on the Shared Control Channel consists of Transport-format—related part, including the HS-
`DSCH transport format and the channelization-code set, and an Hybrid-ARQ-related part. Note that it has not yet
`been agreed if signalling of HS-DSCH power offset is needed.
`Rough ranges for the different signalling parts are given
`"he UE ID is implicitly transmitted in the CRC of the Shared Control Channel. This is included although some
`questions have been raised on this approach. Thus it is recommended that the minutes should mention that this
`may need further studies.
`The basic timing relation is outlined. However, the detailed timing is not given, as there seems to be some
`different opinions on this at this stage.

`Overall physical-channel structure for HS-DSCl—l—related downlink signalling
`Figure 1 illustrates the basic physical—channel structure related to the I 18—] )SCI I—related associated downlink
`
`signalling as seen from the U3 point-of—View. It consists of a downlink DPCH and a number of Shared Control
`Channels. The number of Shared Control Channels can range from a minimum of one Shared Control Channel (M=1)
`to a maximum of four Shared Control Channels (M=4).

`

`HS—DSCH—related downlink signalling information
`Shared Control Channel
`
`For each HS-DSCH TTI, each Shared Control Channel carries HS-DSCH—related downlink signalling for one UE. The
`following information is carried on the Shared Control Channel:
`
`-
`
`Transport-format-related information (TF1)
`The TF1 includes information about the dynamic part of the HS-DSCH transport format, including transport-
`channel-set size, modulation scheme, and coding rate. The TFI also includes information about the set of
`channelization codes onto which HS-DSCH is mapped in the corresponding HS-DSCH TTI. {It has not yet been
`agreed whether the Shared Control Channel should also carry explicit information about the HS-DSCH relative
`power}.
`
`- Hybrid-ARQ-related information (HARQ information)
`The HARQ information includes the block number of the data in the corresponding HS-DSCH TTI. The HARQ
`information also includes information about the redundancy version {see Section on Hybrid-ARQ description} of
`the transmission in the corresponding HS-DSCH TTI.
`
`In addition, the Shared Control Channel carries information (UEID) that identifies the UE for which the Shared
`Control Channel carries HS-DSCH—related signalling.
`
`The different parts of the Shared Control Channel information consists of the following number of information bits
`{minimum/maximum }:
`
`-
`
`-
`
`TF1: {10/16} bits
`
`HARQ information: {5/8} bits ({4/6} bits for block number and {1/2} bits for Redundancy version)
`
`- UEID: {8/16} bits
`
`Note that the number of bits given above is the number of information bits. The number of channel bits transmitted
`over the Shared Control Channel depends on the channel-coding scheme applied to the different sets of information.
`
`A {12/16} bit CRC is calculated over the TF1 + HARQ information + UE 1D.
`
`The structure of the Shared Control Channel is illustrated in Figure 2. Note that the UE 1D is not explicitly
`transmitted but only included in the CRC calculation. {The TF1 should be available as early as possible. The HARQ
`information is not needed early. CRC?}

`
`Downlink DPCH
`
`If a downlink DPCH is present, it carries an HS-DSCH Indicator (HI), in addition to non-HS-DSCH-related physical-
`layer signalling and DCH transport channels. The H1 consists of two information bits that indicate the Shared Control
`Channel that carries the HS-DSCH—related signalling for the corresponding UE. The H1 is transmitted in every third
`slot. If no Shared Control Channel carries HS-DSCH—related signalling to the UE, the HI is not transmitted (DTX).
`Thus, assuming that the HI is transmitted as one QPSK symbol, the possible signalling points are as in Figure 3. {As
`the signalling constellation would anyway include the (0 0) signalling point, the additional signalling points are
`basically forfree}

`Pi indicates Shared Control Channel #i (i e{1, 2, 3, 4}). P0 indicates that no Shared Control Channel
`carries HS-DSCH-related signalling information to the UE.
`
`Timing relations for HS-DSCH-related downlink signalling
`Figure 4 illustrates the timing structure for the HS—DSCH control signalling. The time offset between the Shared
`Control Channel information and the start of the corresponding HS—DSCH TTI equals IHSDSCHCOHM (>0). The time
`offset between the DL DPCH slot carrying the HI and the start of the Shared Control Channel information can vary in
`the interval [0, Tslot] depending on the timing of the downlink DPCH.
