Method for sending rlc pdu and allocating radio resource in mobile telecommunications system and rlc entity of mobile telecommunications

이동통신시스템에서의 rlc pdu 전송 방법, 자원할당 방법 및 rlc 엔티티

Abstract

본 발명은 LTE(Long Term Evolution) 시스템의 MAC 및 RLC 계층이 한정된 무선 자원을 이용하여 RLC STATUS PDU를 전송하는 것에 관한 것이다. 본 발명은 MAC 계층이 논리채널(logical channel)에 무선 자원을 할당하기 위해 논리채널 우선순위화 (Logical Channel Prioritization)를 하는데 있어서, RLC 계층에서 전송해야 하는 RLC STATUS PDU의 크기를 고려하여 무선 자원을 할당하도록 하고, 또한 RLC 계층이 할당된 무선 자원을 사용하는데 있어서 STATUS PDU를 RLC data PDU보다 우선적으로 사용하도록 함으로써, RLC 프로토콜이 STATUS PDU를 전송하지 못하여 교착 상태 (deadlock situation)에 빠지는 것을 방지하는데 있다.
An RLC PDU transmission method in a mobile communication system, a resource allocation method thereof and an RLC entity thereof are provided to operate the protocol regardless of the wireless condition, stably by preferentially assigning resources to an RLC status PDU in an RLC layer. An instruction for available resources is received from an MAC layer(S21). If the size of a received available resource is the same as or bigger than the size of a status PDU which an RLC entity desires to transmit(S22), the RLC entity preferentially assigns the radio resource to the RLC status PDU(S23) and then assigns the rest resources to an RLC data PDU(S24).
