Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for onboarding one or more Multi-AP devices using a device provisioning protocol (DPP) and a Multi-AP communication protocol. In one aspect, a first Multi-AP device may determine, during an onboarding process, DPP configuration information that was derived using the DPP. The first Multi-AP device may establish a Multi-AP network configuration between the first Multi-AP device and a second Multi-AP device using the Multi-AP communication protocol based, at least in part, on the DPP configuration information. In one aspect, the DPP configuration information may be derived remotely by the network operator prior to device deployment. In one aspect, a configurator station (STA) may be delegated as the DPP configurator by the network operator, and may onboard one or more STAs into the Multi-AP network using the DPP and the Multi-AP communication protocol.

Abstract: This disclosure provides methods, devices and systems for using a variable authentication identifier (AID) for access point (AP) privacy. For example, instead of a persistent SSID, an AID is used by a station (STA) to authenticate the AP before connecting to the AP. The AP is associated with a service set, and the STA has stored a secret token associated with the service set. Before connecting to the AP, a broadcasted probe request from the STA includes no identifying information other than the token. The AP generates the AID from the token and provides the AID in a probe response. The STA is able to identify the AP as being associated with a service set and connect to the AP using the token and AID without the token and the AID being used by another device not associated with the service set to identify the AP.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for signaling between an access point (AP) multi-link device (MLD) and a non-AP MLD that support multi-link communication in a wireless local area network (WLAN). In some implementations, a multi-link association may include a first link (referred to as an anchor link) and one or more other links (referred to as auxiliary links). The signaling may include control information to activate or deactivate auxiliary links dynamically based on communication load, throughput requirements, or quality of service (QoS). The signaling also may include requests, acknowledgments, or negotiation regarding multi-link connections. Furthermore, signaling and timing information may be used to coordinate when auxiliary links are used for communication or when to promote an auxiliary link to an anchor link.

Abstract: In accordance with one or more embodiments and corresponding disclosure thereof, various aspects are described in connection with providing shared scheduling request (SR) resources to devices for transmitting SRs. Identifiers related to the shared SR resources can be signaled to the devices along with indications of the shared SR resources in given time durations. Thus, devices can transmit an SR over shared SR resources related to one or more received identifiers for obtaining an uplink grant. This can decrease delay associated with receiving uplink grants since the device need not wait for dedicated SR resources before transmitting the SR. In addition, overhead can be decreased on control channels, as compared to signaling dedicated SR resources and/or uplink grants. Moreover, identifiers related to SR resources can correspond to a grouping of devices, such that a device can transmit over shared SR resources related to a group including the device.

Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for efficient support of variable bit rate (VBR) voice traffic on LTE uplink. In an aspect, a base station may periodically schedule transmission resources for use by a user equipment (UE) for transmitting data on a logical channel, wherein the periodically scheduling grants the UE a fixed first transport block (TB) size of transmission resources at regular intervals, receive an indication from the UE of an amount of data for transmission on the logical channel, and adjust the fixed first TB size of the periodically scheduled transmission resources to a fixed second TB size based on the indicated amount of data. In another aspect, a base station may configure a UE to enable scheduling request masking (SR-masking) on a logical channel, and configure the UE with a threshold amount of data for the logical channel to dynamically disable SR-masking on the logical channel. In another aspect, a UE may receive a configuration to enable scheduling request (SR) masking (SR-masking) on a logical channel, receive a configuration of a threshold amount of data for the logical channel to dynamically disable SR-masking on the logical channel, and decide whether to transmit an SR based on the amount of data to transmit and the threshold amount.

Abstract: Systems and methodologies are described that facilitate employing a variety of medium access control (MAC) header formats in wireless communications. The MAC header formats can be specialized for a particular type of data included in a protocol data unit (PDU). In addition, the MAC headers can have a variable length to accommodate payloads of varying sizes without incurring unnecessary overhead. Further, mechanisms are provided to enable direct access and delivery of control PDUs to associated protocol layers to ensure better quality of service treatment.

Abstract: Access point functionality of a network device may be disabled, resulting in a coverage hole in a communication network and affecting performance of a client device. Various techniques can be implemented for detecting and minimizing coverage holes. In one embodiment, the network device can selectively establish a communication link with the client device depending on whether the client device is in a coverage hole and depending on whether the client device can detect another access point in the communication network. In some embodiments, the client device can determine that it is in a coverage hole in response to detecting a reserved SSID and can accordingly notify a central coordinator of the communication network. In some embodiments, the central coordinator can identify the network device (with disabled access point functionality) that can eliminate the coverage hole and can cause the network device to enable its access point functionality.

Abstract: Systems and methodologies are described that facilitate utilizing timers in conjunction with transmitting buffer status reports (BSR). A prohibit timer can be utilized to determine when BSRs can be transmitted to an eNB. The prohibit timer can be initialized or restarted upon transmitting a BSR to an eNB. A BSR retransmit timer can be used to determine when to retransmit a BSR. The BSR retransmit timer can be initialized upon transmitting a BSR to an eNB and restarted each time an uplink resource allocation is received from the eNB. Once the timer expires, if an uplink transmission buffer contains data (e.g., size>0), the BSR can be retransmitted to the eNB. Control data feedback can additionally be used to determine when to retransmit the BSR. In addition, in either case, the timer duration values can be provided by the eNB.

Abstract: An application may be associated with an application endpoint that is accessed via a wireless local area network. In this disclosure, a wireless station may select and associated with one of a plurality of access points that provides better application throughput to the application endpoint. The application throughput may be based upon a combination of the wireless link rate (between the wireless station and the access point) as well as a measured application data rate (from the access point to the application endpoint). An access point may measure and advertise application data rates for a plurality of application endpoints, including one or more servers coupled to the local area network, a gateway to a wide area network, and/or a server coupled to the wide area network.
