TRANSPORT BLOCK SET SEGMENTATION

摘要

PROBLEM TO BE SOLVED: To provide transport block set (TBS) segmentation.

SOLUTION: Data of a TBS are to be transmitted in a wireless communication system. The system uses adaptive modulation and coding (AMC) and includes a physical layer hybrid automatic repeat request (ARQ) mechanism. Segmentation information for potential segmentation of the TBS is provided. The TBS is transmitted with a first predetermined modulation and coding scheme. It is determined whether the received TBS meets a predetermined quality. When the predetermined quality is not satisfied, a repeat request is transmitted. The first predetermined modulation and coding set is changed to a second predetermined modulation and coding set. In response to the repeat request, the TBS is segmented into a plurality of segments supported by the second predetermined modulation and coding set, in accordance with the segmentation information provided. At least two of the segments are transmitted separately. The transmitted segments are received. The segmentation process may be applied more than once to a particular TBS transmission.
