Title: METHOD AND APPARATUS FOR SUPPORTING HYBRID AUTOMATIC REPEAT REQUEST IN USER EQUIPMENT AND BASE STATION
Abstract:
Disclosed are a method and apparatus for supporting a hybrid automatic repeat request in a user equipment and a base station. The method comprises: firstly, a user equipment receiving a first wireless signal; afterwards, receiving first signaling; and then receiving a second wireless signal, wherein X1 bit blocks are used to generate the first wireless signal, X1 being a positive integer greater than 1, each of the X1 bit blocks comprises a positive integer number of bits, and the X1 bit blocks belong to the same transmission block; only X2 bit blocks from among the X1 bit blocks are used to generate the second wireless signal, X2 being a positive integer smaller than X1; and at least one of {X2, the first signaling} is used to determine X2 cache sizes, and the X2 cache sizes correspond to the X2 bit blocks on a one-to-one basis. The present application increases the number of incremental redundancy bits during retransmission and improves a coding gain of retransmission.
