Abstract

There is provided a method of transmitting feedback information from a mobile terminal in a wireless communication system. The feedback information relates to multi flow High Speed Downlink Packet Access HSDPA transmissions to the mobile terminal from cells belonging to multiple cell sectors. The cell sectors are sometimes simply referred to as sectors. The method comprises transmitting multiple High Speed Dedicated Physical Control Channels HS DPCCHs one HS DPCCH for each sector such that different HS DPCCH channels are used to carry feedback information for cells that belong to different sectors. This opens up for a more flexible HS DPCCH solution allowing multiple HS DPCCHs. In this way the relevant time budget(s) for the mobile terminal and/or base station may be retained or conserved even for multi flow HSDPA transmission scenarios thus avoiding re transmissions of data.
