3.7.3 HSDPA features
The MSM6281 device supports the HSDPA release 5 standard:
■ Supports HS-DSCH (HS-SCCH, HS-PDSCH and HS-DPCCH) in addition to the R99 transport
channels as defined in 3GPP specifications.
■ Supports a maximum of four simultaneous HS-SCCH channels as defined in 3GPP specifications.
■ Supports a maximum of 10 HS-PDSCH channels and supports both QPSK and 16 QAM modulation.
It supports UE category 6 in SW release 2.0 and category 8 in SW release 4.0.
■ Supports CQI, and ACK/NACK on HS-DPCCH channel as defined in 3GPP specifications.
■ Supports all incremental redundancy versions for HARQ, as defined in 3GPP specifications.
■ Can switch between HS-PDSCH and DPCH channel resources, as directed by the network.
■ Can be configured to support any of the two power classes 3 or 4 as defined in 3GPP R5
specifications (25.101).
■ Supports network activation of compressed mode by SF/2 or HLS on the DPCH for conducting inter-
frequency or inter-RAT measurements when the HS-DSCH is active.
■ Supports STTD on both associated DPCH and HS-DSCH simultaneously.
■ Supports CLTD mode 1 on the DPCH when the HS-PDSCH is active.
■ Supports STTD on HS-SCCH when either STTD or CLTD Mode 1 are configured on the associated
DPCH.
■ Supports TFC selection limitation on the UL factoring in the transmissions on the HS-DPCCH as
required in TS 25.133.
