US 9,179,460 B2 · Method of processing control information in a mobile communication system

Abstract

A method of processing control information in a mobile communication system is disclosed, by which an RRC connection setup can be quickly completed and by which control information can be processed without an unnecessary standby of a mobile terminal. The present invention includes the steps of receiving a plurality of protocol data units transmitted plural time from a transmitting side via one common logical channel by an RLC (radio link control) entity operating in a UM (unacknowledged mode) and having a receiving window and a timer, re-ordering a plurality of the received protocol data units using sequence numbers of a plurality of the received protocol data units, the receiving window and the timer, reassembling at least one service data unit by processing a plurality of the re-ordered protocol data units, and delivering the at least one service data unit.

Dependent claims

A method for processing one or more protocol data units (PDUs) by a radio link control (RLC) entity of a user equipment (UE) in a mobile communication system, the method comprising:

receiving the one or more PDUs repeatedly from a single transmitting end via a common control channel (CCCH);
receiving a re-ordering indication indicating whether a re-ordering function is used in an unacknowledged mode (UM) from an upper layer;
receiving size information for a receive window and timer value information for a timer from the upper layer;
and
re-ordering the received one or more PDUs using the receive window, the timer, and sequence numbers of the received one or more PDUs when the re-ordering function is used in the UM.
