Abstract
A method () and corresponding equipment, the method for enabling a Node B/base station () to distinguish different states—HARQ active states and a DTX (non-transmitting) state—of a UE () in respect to use of the feedback HSDPA (high-speed downlink packet access) channel HS-DPCCH over which the UE () sends acknowledgement messages (ACK/NACK) to the Node B () in response to receiving packets via the HSDPA (downlink) data channel HS-DPCH, the method including steps () in which the UE () additionally sends preamble symbols if an acknowledgement message (ACK/NACK) is to be sent in a next time interval but not in the current time interval, and at least one postamble symbol prior to the UE () entering the non-transmitting state (DTX).
