METHOD AND APPARATUS FOR INDICATING HSDPA ACTIVITY INFORMATION

摘要

A method (100) and corresponding equipment, the method for enabling a Node B/ base station (14) to distinguish different states--HARQ active states and a DTX (non-transmitting) state--of a UE (12) in respect to use of the feedback HSDPA (high-speed downlink packet access) channel HS-DPCCH over which the UE (12) sends acknowledgement messages (ACK/NACK) to the Node B (14) in response to receiving packets via the HSDPA (downlink) data channel HS-DPCH, the method including steps (41 42) in which the UE (12) 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 (12) entering the non-transmitting state (DTX).
