6.12d HS-DSCH (MAC-ehs) model for DC/4C -HSDPA (FDD, Rel-8 or later)

34.123-33GPPPart 3: Abstract test suite (ATS)TSUser Equipment (UE) conformance specification

The test model illustrates the relationship between various channels from logical channels to physical channels.

The model enables in the SS to configure DC-HSDPA or 3C/4C-HSDPA:

– MAC-ehs and the served RLC are cell-independent and are configured by using the cell-id =-1. During reconfigurations, cell changes and state transitions, the relevant counters in the RLC are maintained

– to define MAC-ehs and multiplexing of logical channels DTCHs & DCCHs onto MAC-ehs queues;

– to configure HS-DSCH transport channel and MAC-ehs Queues;

– to configure HS-PDSCHs and HS-SCCHs on the serving cell and a secondary HS-DSCH cell for DC-HSDPA;

– to configure HS-DPCCH in the serving cell;

– to define the H-RNTI value(s);

– MIMO and DC-HSDPA do not co-exist in Rel-8;

– to configure combined DC-HSDPA and MIMO in Rel-9 or later Releases.

– to configure HS-PDSCHs and HS-SCCHs on the serving cell and two or three secondary HS-DSCH cells for 4C-HSDPA in Rel-10 or later Releases. MIMO can be configured in the serving and/or secondary cells. When DC-HSUPA is configured in uplink, the first secondary serving HS-DSCH cell is the cell associated with the secondary uplink frequency.

The secondary cells are configured with P-CPICH common channel only according to TS 25.214 [12] section 4.2.4.
