Method of receiving a point-to-multipoint service in a wireless communication system

摘要

The present invention relates to a wireless communication system and user equipment providing wireless communication services, and a method of transmitting and receiving data between a terminal and a base station in an evolved Universal Mobile Telecommunications System (UMTS) that has evolved from a Universal Mobile Telecommunications System (UMTS) or a Long Term Evolution (LTE) system, and more particularly, to a method of receiving a point-to-multipoint service data, and it may be an object of the present invention is to provide an improved method of receiving the point-to-multipoint service data in a wireless communication system in order to minimize a data loss by a reception entity.

1. A method for configuring a receiving entity for a reception of a data block, the method comprising:
determining whether a receiving Unacknowledged Mode (UM) Radio Link Control (RLC) entity processing an UM Data Protocol Data Unit (UMD PDU) is configured for a channel related to a point-to-multipoint service; setting a size of a receiving window in the receiving UM RLC entity, wherein the size of receiving window is set to zero only when it is determined that the receiving UM RLC entity is configured for the point-to-multipoint service related channel, wherein the size of receiving window is set to a pre-defined value when it is determined that the receiving UM RLC entity is not configured for the point-to-multipoint service related channel, wherein the pre-defined value is set based on a size of a sequence number (SN) of the UMD PDU; and processing the UMD PDU according to the size of the receiving window in the receiving UM RLC entity.
