US 12,004,238 B2 · Low latency schemes for peer-to-peer (P2P) communications

Abstract

This disclosure provides systems and methods for requesting wireless resources for peer-to-peer (P2P) communications. In some implementations, a wireless communication device transmits a frame over a wireless medium to an access point (AP), the frame including a medium access control (MAC) header carrying a request for the AP to allocate part of a transmission opportunity (TXOP) for P2P communications between the wireless communication device and a client device. The wireless communication device receives a trigger frame allocating a portion of the TXOP for the P2P communications, and transmits or receives P2P data to or from the client device over the wireless medium during the allocated portion of the TXOP. In some instances, the MAC header of the frame includes a Quality-of-Service (QoS) Control field carrying the request. In some other instances, the MAC header of the frame includes an Aggregated-Control (A-Control) subfield carrying the request.

Dependent claims

A method for wireless communication by a wireless communication device, comprising:

transmitting a frame over a wireless medium to an access point (AP), the frame including a medium access control (MAC) header and carrying a request for the AP to allocate part of a contention-based transmission opportunity (TXOP) obtained by the AP for peer-to-peer (P2P) communications between the wireless communication device and a client device;
receiving, from the AP over the wireless medium, a response frame that includes a MAC header carrying an acknowledgement of the request for the AP to allocate part of the contention-based TXOP obtained by the AP for P2P communications;
receiving, based at least in part on receiving the response frame, a trigger frame over the wireless medium from the AP, the trigger frame allocating a portion of the contention-based TXOP to the wireless communication device for the P2P communications;
and
transmitting or receiving P2P data to or from the client device over the wireless medium during the allocated portion of the contention-based TXOP.

2 more elements

A wireless communication device comprising:

at least one processor;
and
at least one memory communicatively coupled with the at least one processor and storing processor-readable code that, when executed by the at least one processor, is configured to:
transmit a frame over a wireless medium to an access point (AP), the frame including a medium access control (MAC) header and carrying a request for the AP to allocate part of a contention-based transmission opportunity (TXOP) obtained by the AP for peer-to-peer (P2P) communications between the wireless communication device and a client device;
receive, from the AP over the wireless medium, a response frame that includes a MAC header carrying an acknowledgement of the request for the AP to allocate part of the contention-based TXOP obtained by the AP for P2P communications;
receive, based at least in part on receiving the response frame, a trigger frame over the wireless medium from the AP, the trigger frame allocating a portion of the contention-based TXOP to the wireless communication device for the P2P communications;
and
transmit or receive P2P data to or from the client device over the wireless medium during the allocated portion of the contention-based TXOP.
