25 Simplified HS-SCCH type 1 operation
25.3083GPPHigh Speed Downlink Packet Access (HSDPA)Overall descriptionRelease 17Stage 2TS
The Simplified HS-SCCH type 1 operation enables the UE to determine when to expect HS-SCCH type 1 transmissions indicating one HS-PDSCH code and QPSK modulation scheme.
The legacy CQI reports are used as triggering mechanism when low CQI values (from 1 to 6) are reported from the UE to the network. In addition to the CQI based triggering mechanism, HS-SCCH orders can be used to create an interval where the HS-SCCH type 1 is received carrying one HS-PDSCH code and QPSK modulation scheme to extend the usage of the simplified HS-SCCH type 1 transmission independently of the radio conditions.
For both triggering mechanisms, once the UE has transmitted a CQI report over the HS-DPCCH, the UE may expect a HS-SCCH type 1 transmission carrying control information corresponding to one HS-PDSCH code and QPSK modulation scheme in the first available HS-SCCH subframe, once four sub-frames have passed after the end of the sub-frame where the HS-DPCCH was transmitted.
When the network has transmitted a HS-SCCH order for stopping the transmission interval created by the HS-SCCH orders, a fall back to the CQI based triggering mechanism occurs.
The Simplified HS-SCCH type 1 operation is applicable for Cell_DCH state.
