Abstract:
Aspects of the present disclosure provide techniques for high efficiency (HE) basic service set (BSS) operations. In an implementation, a wireless station (STA) can identify a set including one or more modulation coding scheme (MCS) and number of spatial streams (NSS) tuples for HE communications in wireless local area networks (WLANs). The STA can determine whether the set is supported by a BSS and also determine that the STA is to attempt to join the BSS in response to a determination that the set is supported by the BSS. In another implementation, the STA can set a channel width capability for high throughout (HT) communications and very high throughput (VHT) communications in WLANs to be the same as a channel width capability for HE communications in WLANs, and can transmit information that indicates that the STA has the same channel width capability for HT, VHT, and HE communications in WLANs.
Abstract:
Certain aspects of the present disclosure relate to timers used to control switching from SU to MU transmission modes. In some examples, a frame is generated having an indication of multiple timer values for one or more wireless devices to be used for switching from a multiple user (MU) mode to a single user (SU) mode. In other examples, when to switch from a MU mode to a SU mode is determined based on multiple timer values obtained from a frame, and one or more second frames are generated for transmission via the SU mode or the MU mode based on the determination.
Abstract:
A station configured to operate in a wireless network includes low-power protocol circuitry configured to operate according to a low-power protocol coupled to primary protocol circuitry configured to operate according to a first protocol. The low-power protocol circuitry includes a wake-up receiver configured to transition into a receive mode according to a medium access schedule. The wake-up receiver is also configured to receive synchronization signals from a wake-up transmitter of an access point in the wireless network. Each synchronization signal is received according to a slot-skipping transmit schedule of the wake-up transmitter. The low-power protocol circuitry also includes a low-power processor configured to synchronize a clock of the wake-up receiver to a clock of the wake-up transmitter based on at least one of the synchronization signals.
Abstract:
A wireless device for wireless communication is configured to determine a schedule in association with one or more wake times. In addition, the wireless device is configured to determine a lifetime in association with the determined schedule. The lifetime indicates at least one of when the determined schedule associated with the one or more wake times will expire, a validity time associated with the determined schedule, or a boundary associated with the schedule. Further, the wireless device is configured to transmit to one or more wireless devices information indicating the determined schedule associated with the one or more wake times and information indicating the determined lifetime associated with the determined schedule.
Abstract:
A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, the example method may include receiving transmit power related information from a transmitter. The transmit power related information includes at least one of a maximum transmit power, a power backoff per modulation and coding scheme (MCS) information, or an actual transmit power. The example method further includes estimating a modulation and coding scheme (MCS) based at least on the received transmit power related information.
Abstract:
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an AP that requests a plurality of STAs to jointly enable and disable an MRP based on at least one of that each STA of the STAs has uplink traffic with the AP or that each STA of a subset of the STAs has a hidden node. The AP receives, from the STAs, information indicating a communication metric while jointly enabling or disabling the MRP. The AP determines, based on the received information indicating the communication metric, whether the joint enablement of the medium reserving procedure improves communication for the plurality of STAs. The AP requests the STAs to jointly enable the medium reserving procedure for subsequent communication when the joint enablement of the medium reserving procedure improves communication for the plurality of STAs.
Abstract:
A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus may be configured to transmit a request message to a plurality of access points. The request message may include an address reserved for at least one of an access point feature, an access point service, or an access point vendor. The apparatus may be configured to receive a response message from at least one access point of the plurality of access points. The response message may indicate that the at least one access point has the access point feature, is associated with the access point service, or is associated with the access point vendor.
Abstract:
The present disclosure provides techniques for configuring the utilization of request-to-send/clear-to-send (RTS/CTS) protocol procedures based on varying conditions at the STA. For example, an AP may identify one or more conditions, when satisfied, may trigger the STA to either enable or disable uplink (UL) transmissions associated with a RTS/CTS protocol procedure. In some aspects, an AP may determine a transmit opportunity (TXOP) threshold for an STA and may determine whether to broadcast a message having the TXOP threshold to multiple STAs including the STA or unicast the message to the STA. An STA may receive a message from an AP having a TXOP threshold and may replace, based on an indication in the received message, a current TXOP threshold in the STA with the TXOP threshold in the received message. The STA may transmit an UL RTS frame in response to a determination that a planned TXOP duration satisfies the TXOP threshold.
Abstract:
Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to coordinating wakeup times of a receiver able to receive from both a wireless wide area network (WWAN) and a wireless local area network (WLAN). An exemplary method includes obtaining one or more messages (e.g., paging messages) via a receiver and taking one or more actions to align one or more first wakeup periods, during which the apparatus is scheduled to monitor for messages in a first wireless local area network (WLAN), with one or more second wakeup periods, during which the apparatus is scheduled to monitor for messages in a wireless wide area network (WWAN). The exemplary method continues by powering up the receiver for a duration spanning at least one of the one or more first wakeup periods and at least one of the one or more second wakeup periods, monitoring for messages in the first WLAN during the at least one of the one or more of the first wakeup periods, while the receiver is powered up for the duration, and monitoring for messages in the WWAN during the at least one of the one or more of the second wakeup periods while the receiver is powered up for the duration.
Abstract:
Techniques for reducing delay in scheduling traffic transmission in an overlapping basic service set (OBSS) environment by modifying backoff mechanisms are disclosed. In some examples, a device (e.g., station (STA) or access point (AP)) may decode at least a portion of a preamble of a received packet to determine whether the packet is sent by a member of an OBSS (e.g., STA or AP from a different BSS). Backoff operations are typically deferred as a result of the decoding. Aspects of the present disclosure provide a method, apparatus, and system to reduce delay in scheduling traffic transmissions by resuming the backoff operations prior to expiration of the period reserved for an OBSS packet by the network allocation vector (NAV). In other words, the device may not honor the NAV of the OBSS packet, and instead perform spatial reuse by transmitting another packet (or signal) on the same frequency channel during the NAV of the OBSS packet.
