Method and system for improving the efficiency of packet transmission in a multi-user wireless communication system

摘要

A method and system utilized in a wireless communication system transmitting and receiving a multi-user packet is disclosed. The communication system includes a transmitter and a plurality of users in communication therewith. The method and system comprise determining a lowest coding scheme for transmitting the packet; and deriving a coding rate for the efficient transmission of the packet from a standard coding rate by de-puncturing bits in the packet. A system and method in accordance with the present invention provides for an efficient utilization of packet length, and improves the reliability by improving SNR, by lowering the MCS, un-puncturing, and/or repetition. More efficient packed data rates are also provided and both Tx and Rx compute parameters independently.

1. A method utilized in a wireless communication system for transmitting and receiving a multi-user packet which comprises a plurality of user packets, the communication system including a transmitter and a receiver, the method comprising:
determining a longest user packet in the multi-user packet; determining a lowest coding rate of a coding scheme for de-puncturing at least one user packet other than the longest user packet; and de-puncturing the at least one user packet from a standards compliant coding rate to extend the at least one user packet length for transmission.
