MAC and RLC architecture and procedures to enable reception from multiple transmission points
Abstract
A method for use in a wireless communication system for two-stage reordering of received protocol data units (PDUs). The method comprising receiving PDUs from Node-Bs, wherein each of the received PDUs has a transmission sequence number (TSN), reordering the received PDUs from Node-Bs using the TSN in a MAC layer in different reordering queues, delivering the received PDUs from reordering queues to one logical channel in the RLC layer, reordering the received PDUs in the RLC layer based on a sequence number (SN), starting a timer when at least a RLC PDU is missing based on SN of the RLC PDU, and transmitting a status report indicating a missing RLC PDU based on SN of the RLC PDU if the timer expires, wherein transmission of the status report is delayed if a RLC PDU is missing based on SN of the RLC PDU and the timer is running.
