Embodiment Construction

[0021] A station, such as a wireless local area network (WLAN) station, may communicate via an access point (AP) transport infrastructure, as well as peer-to-peer (P2P) communication with a peer device, which may be another station. However, due to the channel access priority of the AP over the WLAN station or the congested WLAN medium, the station may not be able to send the P2P traffic in a timely manner even though the P2P traffic queued at the station has a higher priority than the infrastructure traffic queued at the station. The same is true of priority.

[0022] Some embodiments enable concurrent P2P communication via scheduled resource units (RUs) allocated by the AP. For example, the AP may use the trigger frame to schedule uplink (UL) multi-user (MU) access for a first station among multiple stations by allocating RUs to the first station. Instead of using the allocated RUs for UL infrastructure communication with the AP, the first station may use the allocated RUs ...

Abstract

The invention relates to an apparatus and method for scheduled uplink multi-user access. Some embodiments include an apparatus and method for enabling concurrent peer-to-peer (P2P) communications viaa scheduled resource unit (RU) allocated by an access point (AP). For example, the AP may use a trigger frame to schedule uplink (UL) multi-user (MU) access for a first station of a plurality of stations by allocating an RU to the first station. Instead of using the allocated RU for UL infrastructure communications with the AP, the first station may utilize the allocated RU for a P2P communications with a second station. In some embodiments the AP facilitates RU utilization for P2P communications between stations. In some embodiments, the first station uses the allocated RU and the AP may be unaware of the P2P communications.

Description

[0001] Cross References to Related Applications [0002] This patent application requires the title "Apparatus and Method for Scheduled Uplink Multi-User Access with Concurrent Peer-to-Peer Communications" filed on June 28, 2018 Apparatus and method for the benefit of US Provisional Application No. 62 / 691,522, which is incorporated herein by reference in its entirety. technical field [0003] Embodiments described herein relate generally to channel access in wireless communications. Background technique [0004] Access points (APs) typically access the wireless local area network (WLAN) medium with higher priority than WLAN stations. Thus, the WLAN medium may be occupied by AP-transmitted and received infrastructure traffic for extended amounts of time. In some cases, a WLAN station may have urgent peer-to-peer (P2P) communications to transmit to peer devices, where the P2P communications have higher priority than pending infrastructure communications. However, due to th...
