4.6J Coding/Multiplexing for HS-SCCH orders type B (1.28Mcps TDD only)

25.2223GPPMultiplexing and channel coding (TDD)Release 17TS

HS-SCCH orders type B are commands sent to the UE using HS-SCCH. No HS-PDSCH is associated with HS-SCCH orders.

HS-SCCH order type B may be used when any of the following two conditions is met:

– CONTROL_CHANNEL_DRX_STATUS is TRUE and UE is configured in MIMO mode while the variable MIMO SF mode for HS-PDSCH dual stream is SF1/SF16;

– The variable HS_DSCH_SPS_STATUS is TRUE, and UE is configured in MIMO mode while the variable MIMO SF mode for HS-PDSCH dual stream is SF1/SF16.

The following information is transmitted by means of the HS-SCCH order type B physical channel.

– Order type (3 bits): x_odt,1, x_odt,2, x_odt,3

– UE identity (16 bits): x_ue,1, x_ue,2, …, x_ue,16

The coding for HS-SCCH orders type B is specified in subclause 4.6F.

4.6J.1 HS-SCCH orders type B information field mapping

4.6J.1.1 Order type mapping

If x_odt,1, x_odt,2, x_odt,3= ‘001’, then the HS-SCCH order is an order to release the allocated semi-persistent HS-PDSCH resources when UE is in CELL_DCH state.

If x_odt,1, x_odt,2, x_odt,3= ‘010’, then the HS-SCCH order is DRX Activation order when UE is in CELL_DCH state.

If x_odt,1, x_odt,2, x_odt,3= ‘011’, then the HS-SCCH order is DRX De-activation order when UE is in CELL_DCH state.

4.6J.1.2 UE identity mapping

The UE identity is the HS-DSCH Radio Network Identifier (H-RNTI) defined in [12]. This is mapped such that x_ue,1 corresponds to the MSB and x_ue,16 to the LSB, cf. [14].
