Patent ID: 7545731

Claim:
A buffer size management for a rate matching system which comprises: a first rate matching stage which matches a number of input bits coming from a transport channel comprising a high-speed downlink shared channel (HS-DSCH) associated with a set of at least one high-speed physical downlink shared channel (HS-PDSCH) on which a block of data bits are transmitted from a base station of a communications network to one or more pieces of user equipment (UE), to a selected number of intermediate bits as determined by the buffer size management system a virtual buffer to store the selected number of intermediate bits until reception by said base station of an acknowledgment indicating a correct reception of said block of data bits by said one or more pieces of user equipment (UE) using a hybrid automatic repeat-request (HARQ) procedure, and a second rate matching stage which matches the selected number of intermediate bits to a number of output bits equal to a maximum number of bits said set of the at least one high-speed physical downlink shared channel is transmitted in a given time interval, without adding bits.
