Embodiment

[0120] 1. A method used in a station (STA), the method comprising:

[0121] receiving a first peer-to-peer communication frame; and

[0122] A second peer-to-peer communication frame responsive to the first peer-to-peer communication frame is transmitted.

[0123] 2. According to the method described in embodiment 1, the method also includes:

[0124] Where a STA is not in direct communication with another STA, it communicates with an access point (AP) during a peer-to-peer communication session with the other STA.

[0125] 3. The method of embodiment 1 or 2, wherein the STA is in power saving mode (PSM).

[0126] 4. The method according to any one of the preceding embodiments, the method further comprising:

[0127] A scheduled or non-scheduled AP connection period or period indicated in the first peer-to-peer communication frame is rejected.

[0128] 5. The method as in any one of the preceding embodiments, wherein the second communication frame indicates an alternative ...

Abstract

A method and apparatus may be used for peer-to-peer communication. The method and apparatus may allow for network connectivity during the peer-to-peer communication session. The network connectivity may be provided via Scheduled and / or Unscheduled AP Connection times / periods. A station (STA) may be configured to negotiate access point (AP) Connection times / periods with a peer STA for a direct link which may be on a basic service set (BSS) channel or on a non-BSS channel. The STAs may communicate with the AP during the agreed AP Connection times / periods and return to the direct link for peer-to-peer communication.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 243,833, filed September 18, 2009, the contents of which are incorporated herein by reference. Background technique [0003] A wireless local area network (WLAN) in an underlying Basic Service Set (BSS) mode may have an access point (AP) for the BSS and one or more stations (STA) associated with the AP. The AP may access or connect to a Distribution System (DS) or another type of wired or wireless network that carries traffic both inside and outside the BSS. The service initiated from outside the BSS to the STA can be delivered through the AP. Traffic initiated from STAs to destinations other than the BSS can be sent by the AP to the respective destinations. Traffic between STAs within a BSS may be transferred through an AP, where a source STA may send traffic to an AP and the AP transfers traffic to a destination STA. The service between STAs in...
