Abstract

A first Station (STA) in a wireless network is provided. The first STA establishes a peer-to-peer (P2P) link with the second STA. The first STA sends a first frame to an Access Point (AP) requesting the AP to assist in securing P2P communications between the first STA and the second STA. In response to the first frame, the first STA receives a second frame from the AP indicating assistance that the AP can provide in response to the first frame. The first STA then communicates with the second STA based on the assistance provided from the AP.

Description

Peer-to-peer communication in a wireless network Technical Field The present disclosure relates generally to wireless communication systems, and more particularly, to peer-to-peer (P2P) communication in wireless communication systems, for example, but not limited to. Background Since the late 90 s of the 20 th century, wireless Local Area Network (WLAN) technology has evolved toward increasing data rates and continues to grow in various markets such as home, business, and hotspots. WLAN allows devices to access the internet in the 2.4GHz, 5GHz, 6GHz, or 60GHz frequency bands. WLAN is based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard. The IEEE 802.11 family of standards aims to increase speed and reliability and extend the operating range of wireless networks. WLAN devices are increasingly required to support various delay-sensitive applications or real-time applications such as Augmented Reality (AR), robotics, artificial Intelligence (AI), cloud computing, and unmanned vehicles. In order to achieve the extremely low latency and extremely high throughput required for such applications, multi-link operation (MLO) has been proposed for WLANs. WLANs are formed by WLAN devices within a limited area such as a home, school, apartment, or office building. Each WLAN device may have one or more Stations (STAs) such as an Access Point (AP) STA and a non-access point (non-AP) STA. The MLO may enable a non-AP multi-link device (MLD) to establish multiple links with an AP MLD. Each of the multiple links may independently enable channel access and frame exchange between the non-AP MLD and the AP MLD, which may reduce latency and increase throughput. The description set forth in the background section should not be assumed to be prior art because it is merely set forth in the background section. The background section may describe aspects or embodiments of the present disclosure. Disclosure of Invention One aspect of the present disclosure provides a first Station (STA) in a wireless network. The first STA includes a memory and a processor coupled to the memory. The processor is configured to cause a peer-to-peer (P2P) link to be established with the second STA. The processor is configured to cause a first frame to be sent to an Access Point (AP) requesting the AP to assist in securing P2P communications between a first STA and a second STA. The processor is configured to cause a second frame to be received from the AP indicating that the AP is capable of providing assistance in response to the first frame. The processor is configured to cause communication with the second STA based on assistance provided from the AP. In some embodiments, assistance is associated with reducing interference to the P2P link from a Basic Service Set (BSS) corresponding to the AP. In some embodiments, the assistance is associated with a channel access opportunity of the first STA or the second STA. In some embodiments, the first STA is associated with an AP and the second STA is not associated with an AP. In some embodiments, the first STA is not associated with the AP and the second STA is associated with the AP.
