    摘要: 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.

    摘要: When a UE (12) is configured with MF-HSDPA and HARQ-ACK information associated with cells (14, 16) (characterized by potentially different downlink timing) is jointly encoded, only part of the existing Rel-9 HARQ-ACK codebook is reused. In one embodiment, only the codebook conflict arising from reuse of encodings is resolved. This is achieved by introducing a new codeword for at least one of the HARQ-ACK code words that are used multiple times in the existing Rel-9 codebook. In another embodiment, all codewords in the Rel-9 HARQ-ACK codebook having a Hamming distance smaller than a predetermined value (but not all codewords) are replaced. In yet another embodiment, all codewords in the Rel-9 HARQ-ACK codebook having a Hamming distance smaller than a predetermined value (but not all codewords) that would cause ambiguity at the NodeB receiver (i.e. where the interpretation of the HARQ-ACK information for one cell (14) depends on the number of streams transmitted at the other cell (16)) are replaced.
