A plurality of acknowledgement procedures is sent on an uplink to the network, in response to the received reconfiguration message causing the UE to transition from the CELL_DCH state to the non-dedicated channel state.

Abstract: Methods and apparatus for avoiding power scaling and controlling transmit power in uplink data transmission are provided. If a user equipment (UE) would be transmit-power limited when transmitting data concurrently on an uplink high speed dedicated physical control channel (HS-DPCCH) and an uplink data channel, the UE may forgo building data for transmission on the uplink data channel to avoid power scaling.

The UE may also boost transmission power of a negative acknowledge transmission above network-specified power level.

Abstract: An apparatus and a method are provided for improving user experience in a multi-radio access bearer (multi-RAB) wireless communication system. After a user equipment establishes a circuit-switched communication link and a packet-switched communication link with a core network, it may receive an indication of an error associated with the packet-switched communication link. Here, if the value of a timer such as the RAB re-establishment timer T314 has a predetermined value (e.g., 0), the user equipment may release the packet-switched communication link, and maintain the circuit-switched communication link. The packet-switched communication link may then be re-established. In this fashion, errors that may occur on the data call need not interrupt a voice call.
