METHOD AND SYSTEM FOR CONTROL SIGNALLING ENABLING FLEXIBLE LINK ADAPTION IN A RADIOCOMMUNICATION SYSTEM

摘要

Control signalling for systems employing link adaptation and incremental redundancy is described. A link adaptation/incremental redundancy message ca n be transmitted from a receiving entity to a transmitting entity to inform th e transmitting entity of the receiving entity's incremental redundancy status or preference. Another message, which indicates whether resegmentation should b e performed for retransmitted blocks can also be transmitted from a receiving entity to a transmitting entity. Both of these messages can be used by the transmitting entity to determine an appropriate modulation/coding scheme for subsequent transmissions of both original data blocks and retransmitted data blocks. The messages can be used together or independently in either link (uplink or downlink) between a base station and a mobile station in a radiocommunication system.
