SYSTEM AND METHOD FOR PACKET INFORMATION INDICATION IN COMMUNICATION SYSTEMS

摘要

A wireless device is described that may selectively include resource allocation information in a frame to be transmitted to one or more other wireless devices. The resource allocation may indicate channel/sub-channel assignment for each wireless device. The wireless devices may each utilize this received resource allocation information to determine the appropriate segment/sub-band of the transmission that is intended for their receipt/consumption. A first signaling field (e.g., HE-SIG-A) may indicate whether the resource allocation information is present in a second signaling field (e.g., HE-SIG-B) of the frame. For example, a single bit may be toggled to indicate the presence of the second signaling field and therefore the presence of the resource allocation information. Alternatively, multiple bits may be used to indicate the length of the second signaling field (e.g., a length of zero indicates the absence of the second signaling field and accordingly the absence of the resource allocation information).

主权项

1. A method for performing wireless communications, the method comprising:
generating, by a first wireless device, a frame for transmission to a second wireless device, wherein generating the frame includes:
adding a first signaling field to the frame, wherein the first signaling field assists a second wireless device that receives the frame to process the frame,determining to not include a second signaling field in the frame when the frame is transmitted as a single user transmission to the second wireless device, anddetermining to include and adding a second signaling field to the frame when the frame is transmitted as a downlink multi-user transmission; and transmitting, by the first wireless device, the frame to the second wireless device over a wireless channel.
