METHODS AND APPARATUS FOR MULTIPLEXING PEER-TO-PEER TRAFFIC AND/OR ACCESS POINT TRAFFIC

摘要

A method comprises receiving a first message over a first portion of a frequency bandwidth. The first message includes an identifier of a transmitting first wireless device and an intended recipient second wireless device. The method comprises determining whether a second portion of the frequency bandwidth is idle for a duration of time including at least one of a PIFS time and a time required for a backoff timer to expire. The method comprises transmitting a second message over the second portion of the frequency bandwidth by a third wireless device, the second message having a limited transmission time that is not to extend beyond a transmission time of the first message, thereby allowing an availability of the first and second portions for use after an end of the transmission time of the first message. The third wireless device is not an intended recipient of the first message.

主权项

1. A method for wireless communication, comprising:
receiving a first message over a first portion of a frequency bandwidth, wherein the first message includes an identifier of a transmitting first wireless device and an intended recipient second wireless device, determining whether a second portion of the bandwidth is idle for a duration of time including at least one of a point coordination function interframe space (PIFS) time and a time required for a backoff timer to expire, and transmitting a second message over the second portion of the frequency bandwidth by a third wireless device, the second message having a limited transmission time that is not to extend beyond a transmission time of the first message, thereby allowing an availability of the first and second portions of the frequency bandwidth for use at least after an end of the transmission time of the first message, wherein the third wireless device is not an intended recipient of the first message.
