SYSTEM AND METHOD FOR MULTI-POINT HSDPA COMMUNICATION UTILIZING MULTI-LINK RLC SUBLAYER

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for wireless communication which provides a system and method for Multi-Point HSDPA communication utilizing a multi-link RLC sublayer.SOLUTION: The invention provides a multi-link RLC sublayer in an RNC 802 capable of allocating RLC PDUs among a plurality of MAC entities 804, 806 for use in a Multi-Point HSDPA network. The invention addresses issues relating to out-of-order delivery of the RLC PDUs to UE 808, such as unnecessary retransmissions. The multi-link RLC sublayer distinguishes between sequence number gaps that are caused by physical layer transmission failures and sequence number gaps caused merely by skew.
