Abstract: An electronic device that transmits a frame to a second electronic device is described. In particular, during operation, an interface circuit in the electronic device (such as an access point in a WLAN) may transmit the frame to the second electronic device using a Wi-Fi communication protocol. The frame may include information cancelling a previously specified NAV protected time in a preamble of the frame. For example, the information may include a CF-End indication. Moreover, the information may be included in a MAC header of the frame and, more generally, in a preamble of a high efficiency (HE) physical layer convergence protocol (PLCP) protocol data unit (PPDU). Furthermore, the electronic device may transmit the frame in response to a block acknowledgment (BA) from the second electronic device.

Abstract: Disclosed herein are method, system, and computer program product embodiments for utilizing multiple traffic identifiers (TIDs) in a single user (SU) transmission. Some embodiments may operate by forming a SU multiple TID data unit that includes first data associated with a first access category and a first TID and second data associated with a second access category and a second TID. Some embodiments may further operate by transmitting the SU multiple TID data unit during a transmission opportunity based on configuration parameters associated with the transmission opportunity.

Abstract: An access point (AP) in a wireless local area network (WLAN) uses a protocol to determine frequency/time resource allocations of resource units (RUs) in parallel with data transfer to and from WLAN stations (STAs). The AP generates a sounding table associating STAs with RUs for uplink (UL) and downlink (DL). The AP processes the sounding table to create a channel map table and then the AP allocates particular RUs to particular STAs. The STAs then receive and transmit data from and to the AP over the allocated RUs. This approach achieves good throughput while reducing the use of signaling and pilot overhead associated with channel sounding. To avoid interruption of ongoing transmissions, a newly arriving STA is grouped and sounded with other STAs. The protocol includes a joint sounding and data epoch followed by a determination of the channel map table.

Abstract: During operation, an interface circuit in an electronic device may receive, from a second electronic device (such as an access point in a WLAN), an uplink trigger frame that may specify an access category. In response to the uplink trigger frame, the electronic device may first include data associated with the specified access category in one or more frames, and then may transmit the one or more frames to the second electronic device. Moreover, when all the data associated with the specified access category has been transmitted or when there is no data associated with the specified access category, and when there is leftover time in an allocation associated with the uplink trigger frame, the interface circuit may transmit the one or more frames to the second electronic device with additional data associated with another access category that is different from the specified access category.

Abstract: An electronic device communicates frames with an access point (AP) by receiving, from the AP, a frame header that includes information specifying a first set of tones of an OFDMA communication, the first set of tones associated with first resource block subchannels having a first bandwidth used by the AP to transmit a frame payload. The electronic device obtains a second set of tones associated with second resource block subchannels having a second bandwidth that differs from the first bandwidth, and receives the frame payload using the OFDMA communication, the second resource block subchannels, and the second set of tones. Alternatively, an electronic device dynamically switches a channel-access mode when communicating a frame with the AP depending on whether the communication includes a primary 20 MHz channel. In a technique, an MU-PPDU is communicated using a frame via a non-primary 20 MHz channel without using the primary 20 MHz channel.

Abstract: A wireless local area network (WLAN) station (STA) reports, with a medium access control (MAC) frame, a buffer status of an urgent traffic identifier (TID) to a second STA. In some embodiments, the second STA is also an access point (AP). The delay in reporting is reduced by providing a buffer status report for the urgent TID in a data frame being transmitted to carry data for a current TID. The buffer status report, in some embodiments, provides the value of the urgent TID. In some embodiments, the buffer status report provides an indication of the amount of data in a buffer corresponding to the urgent TID. In some embodiments, the buffer status report is based on an aggregated measure of more than one buffer with data awaiting transmission. The transmission of the MAC frame, in some embodiments, is unsolicited.

Abstract: An access point selects a channel access policy for an electronic device in a wireless local area network (WLAN). During operation, an interface circuit of the access point receives a channel access preference from the electronic device. The channel access preference includes: a multi-user trigger-based channel access technique, a single-user contention-based channel access technique, or both. The interface circuit selects the channel access policy for the electronic device based, at least in part, on the received channel access preference. The channel access policy can also be selected based at least in part on a communication performance metric associated with communication in the WLAN. The interface circuit communicates the selected channel access policy to the electronic device, which subsequently accesses a communication channel and communicates packets with the access point in accordance with the channel access policy.

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).

Abstract: Methods, systems, and devices are described for saving power in wireless communications. One aspect includes providing an indication of a sleep duration for transmission to a wireless node, communicating with the wireless node during a target wakeup time (TWT), wherein the communication comprises at least one of providing data for transmission to the wireless node or obtaining data received from the wireless node, and refraining from providing data for transmission to the wireless node for at least the indicated sleep duration based at least in part on timing of the communication. Another aspect includes receiving an indication of a sleep duration from a wireless node, communicating with the wireless node during a time slot of a TWT, and entering a sleep mode for the indicated sleep duration based at least in part on timing of the communication with the wireless node during the time slot of the TWT.

Abstract: In a particular aspect, a method includes receiving, at a long-term evolution (LTE) circuitry of wireless device from a wireless local area network (WLAN) circuitry of the wireless device while the LTE circuitry has control of at least one antenna of the wireless device, a request for control of the at least one antenna. Communications by the LTE circuitry using the at least one antenna corresponds to a first frequency band, communications by the WLAN circuitry using the at least one antenna correspond to a second frequency band, and the first frequency band at least partially overlaps the second frequency band. The method further includes sending a response from the LTE circuitry to the WLAN circuitry based on data included in the request.

Abstract: A multi-channel wireless device for participating on a plurality of networks. The wireless device switches from a first channel associated with a first network to a second channel associated with a second network if the wireless device has a channel dwell time on the first channel equal to or greater than a maximum channel allowance time interval for the first channel, wherein the maximum channel allowance time interval for the first channel is given by a channel switching time subtracted from a Beacon interval associated with the first network divided by the total number of networks that the wireless device is participating with.

Abstract: The listen interval of a WLAN client is selected to have one of a plurality of values, including a start listen interval (SLI) and one or more longer listen intervals (e.g., transient listen interval (TLI), maximum listen interval (MLI)). The listen interval is set to SLI in response to (1) detecting that an applications processor of the WLAN client is in an awake state, (2) detecting transmit/receive activity on the wireless link, and (3) failing to detect an expected beacon signal on the wireless link. If the listen interval is set to MLI (or TLI) and the WLAN client fails to detect an expected beacon signal (beacon miss), the listen interval is temporarily set to SLI. If the WLAN client then detects an expected beacon signal before detecting a predetermined number of consecutive beacon misses, the listen interval is immediately returned to the original listen interval MLI (or TLI).

Abstract: A mobile communication device includes a receiver system configured to receive unicast data packets and non-unicast data packets. The receiver system may include a hardware packet filter. The mobile communication device further includes a processor coupled to the receiver system. The processor may be configured to detect a power state change and activate the hardware packet filter at the receiver system in response to the power state change indicating a power-conservation state being entered. When the hardware packet filter is activated, the unicast data packets received at the receiver system may be provided to the processor to be filtered and the non-unicast data packets received at the receiver system are dropped at the receiver system. When the hardware packet filter is not activated, the unicast data packets and the non-unicast data packets received at the receiver system may be provided to the processor.
