    Abstract: A method and apparatus provide for scheduling reverse link transmission for a mobile station in a timely manner. A base station (101) may transmit on a forward link high rate channel and a forward link low rate channel to a mobile station during a common time slot. The high rate and low rate channels may be respectively the F-PDCH and the F-PDCCH. The base station may transmit a reverse link transmission scheduling information on the low rate channel. The mobile station may schedule transmission on the reverse link channel, such as R-SCH, based on the data received on the low rate channel. Since the low rate channel has only scheduling data (16 bits) and the high rate channel may have no data (null data) at all, the base station may decide to transmit the reverse link scheduling information to the mobile station very quickly on the forward link.

    Abstract: This disclosure provides systems and methods for requesting wireless resources for peer-topeer (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.

    Abstract: This disclosure provides systems, methods, and apparatus for managing data traffic in restricted target wake time (TWT) service periods (SPs). In some aspects, an access point (AP) receives a request frame from a wireless station (STA) associated with a client device via a peer-topeer (P2P) link, the request frame indicating that the STA intends to exchange P2P communications with the client device during a r-TWT SP scheduled on a wireless medium. The AP obtains a transmission opportunity (TXOP) on the wireless medium during the r-TWT SP, the request frame identifying the client device. The AP transmits a trigger frame on the wireless medium responsive to obtaining the TXOP, the trigger frame allocating a portion of the obtained TXOP for P2P communications between the STA and the client device, wherein at least one of the response frame or the trigger frame indicates a Network Allocation Vector (NAV) exception for the client device.

    Abstract: This disclosure provides methods, devices and systems for protecting latency-sensitive communications, during restricted target wake time (r-TWT) service periods (SPs), from non-legacy STAs that do not support r-TWT operation. Some implementations more specifically relate to preventing STAs that are not members of an r-TWT SP from acquiring transmit opportunities (TXOPs) that would otherwise overlap with the start of the r-TWT SP. In some implementations, the AP may require all non-legacy STAs associated with its basic service set (BSS) to support r-TWT operation. In some other implementations, the AP may attempt to capture a wireless channel associated with the r-TWT SP within a fixed period preceding the r-TWT SP. In some other implementations, the AP may require all associated STAs to transmit a request-to-send (RTS) frame when attempting to acquire a TXOP. Still further, in some implementations, the AP may limit the duration of TXOPs acquired by non-member STAs.

    Abstract: Disclosed are techniques for wireless communication. In an aspect, an access point (AP) communicates with at least one wireless station (STA) and supporting a plurality of communication devices and communication modes on a communication medium, establishes a single-link communication mode with the at least one wireless STA and at least one communication device of the plurality of communication devices over a single-link, establishes a multi-link communication mode with the at least one wireless STA and the at least one communication device over a multi-link, and dynamically transitions between the single-link communication mode and the multi-link communication mode based upon a determination related to a best mode of delivery for a next period.

    Abstract: This disclosure provides methods, devices and systems related multi-link wireless communication. A method may include establishing, between the first WLAN device and a second WLAN device, a multi-link association that enables a first wireless communication link and a second wireless communication link. The method may include determining a temporal key for the multi-link association. The method may include encrypting a first and second media access control (MAC) protocol data unit (MPDU) based on the temporal key. The method may include preparing a first frame including the encrypted first MPDU and a second frame including the encrypted second MPDU. The method may include assigning packet numbers from a set of sequential packet numbers to the first and second frames. The method may include transmitting the first frame over the first wireless communication link and the second frame over the second wireless communication link.
