6.13.1 MAC-e/MAC-es test model

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

The E-DCH model illustrates the relationship between various channels from logical channel to physical channels. In this model the TTCN writer can:

– define MAC-e/es and multiplexing of logical channels onto MAC-d flows;

– configure E-DCH transport channel and MAC-d flows;

– configure E-DPDCH, E-DPCCH, E-HICH, E-RGCH and E-AGCH.

MAC-es 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.

For the reason of simplicity, the E-DCH testing model does not shown the relation between E-DCH and related DCH and HS-DPCH, however the TTCN writer shall understand that the E-DCH active set is a subset of the DCH active set, when configuring E-DCH in the SS the TTCN writer shall keep this requirement respected.

During the active set updating (soft handover), the test case configurations may involve more than one cell. Those cells are under the control of the same Node B (intra-node) or under several Node B’s (inter-node). For the signalling testing no macro diversity is required in the SS. In such test configurations only one E-DPDCH is necessary to be configured (together with corresponding E-DCH) for each Node B. Preferably, the E-DPDCH in the serving E-DCH cell controlled by the serving Node B is chosen for the configuration. In the inter-node soft handover cases, the E-DPDCH in a Non-serving RL cell of another Node B may require to be configured, instead of the one in the serving E-DCH cell. When the configuration involves several Node B’s only one MAC-e (Node B) is necessary to be connected to the MAC‑es. All possible connections are represented by dashed line and the preferable connection is the connection between MAC‑es and the Node B controlling the serving E-DCH cell.

Since the UL-DPCCH is needed as reference channel for the E-DPCCH the UL-DPCH is configured in every cell where an E-DCH is configured (i.e. in serving and non-serving cell). In order to simplify the implementation and to avoid macro diversity in all non-serving cells the UL-DPCH is configured without the associated transport channel configuration, i.e. the physical channel is not connected to MAC-d.
