Abstract
When employing HARQ in soft handover (SHO) in a mobile communication system, a mobile station in communication with multiple base stations is signaled by each of the base stations when a packet sent by the mobile station is correctly received. However, while one or more base stations may have received the transmission correctly, others may not have, and retransmission may be called for. To address the possibility of having to resend such a packet, the mobile station of the invention retransmits only if a selected number of the base stations received the transmission incorrectly and does not if at least one base station received the original transmission correctly. The mobile transmits at a rate selected according to a rule from data rate information or signaling received from one or more of the base stations. The network is then able to retrieve the packet from one or more of the base stations which have received it correctly and to supply it to another or others which have not.
