Filed:

Appl. No.:

12/273506

Inventors:

Sirikiat Lek Ariyavisitakul - Alpharetta GA, US
Mark Kent - Vista CA, US
Tak K. Lee - Irvine CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H04L 5/12
H04L 23/02
H04L 27/06
H03M 13/00
G06F 11/10

US Classification:

375341, 375259, 375262, 714758, 714807

Abstract:

Flexible rate matching. No constraints or restrictions are placed on a sending communication device when effectuating rate matching. The receiving communication device is able to accommodate received transmissions of essentially any size (e. g. , up to an entire turbo codeword that includes all systematic bits and all parity bits). The receiving communication device employs a relatively small-sized memory to ensure a lower cost, smaller sized communication device (e. g. , handset or user equipment such as a personal wireless communication device). Moreover, incremental redundancy is achieved in which successive transmissions need not include repeated information therein (e. g. , a second transmission need not include any repeated information from a first transmission). Only when reaching an end of a block of bits or codeword to be transmitted, and when wrap around at the end of such block of bits or codeword occurs, would any repeat of bits be incurred within a later transmission.
