Abstract: A method and apparatus for concurrent wireless communications on multiple channels of the same frequency band. A wireless device determines when a first transceiver chain of the wireless device is to receive a first data signal. The wireless device then transmits a second data signal via a second transceiver chain of the wireless device based at least in part on the determination. The wireless device further suspends the transmission of the second data signal in response to the determination that the first transceiver chain is to receive the first data signal.

Abstract: A method and apparatus for concurrent wireless communications on multiple channels of the same frequency band. A wireless device receives a first data signal via a first transceiver chain while concurrently initiating a transmission of a second data signal via a second transceiver chain of the wireless device. The wireless device suspends updates to one or more tracking loops of the first transceiver chain in response to initiating the transmission of the second data signal. The updates to the one or more tracking loops may be suspended prior to transmitting the second set of data from the second transceiver chain. The wireless device may subsequently resume updates to the one or more tracking loops of the first transceiver chain after completing the transmission of the second data signal.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for using a shortened block acknowledgement (BlockAck) frame capable of acknowledging fragments. Such a shortened BlockAck frame may include a bitmap field having a shorter length than that of a basic BlockAck frame in the IEEE 802.11 standard (i.e., <128 octets). One example method for wireless communications generally includes receiving a plurality of protocol data units (PDUs) (e.g., media access control (MAC) protocol data units (MPDUs)); determining whether each of the PDUs was successfully received and whether each of the PDUs is associated with a non-fragmented service data unit (SDU) (e.g., MAC service data unit (MSDU)) or a fragmented SDU; and outputting for transmission a shortened BlockAck frame comprising a bitmap field indicating a receive status for the non-fragmented and fragmented SDUs based on the determination.

Abstract: Methods, systems, and devices are described for wireless communication at a wireless device having collocated radios employing different radio access technologies (RATs). For example, a second radio of the wireless device may receive a first scheduling message. The first scheduling message may include information relating to timing, priority, transmission power, and radio capabilities. Using this scheduling message, a determination of whether a first radio employing a first RAT and the second radio employing a second RAT can transmit in parallel may be made. A first transmission on the first radio may be coordinated with a second transmission on the second radio based on the determination of whether the first radio and the second radio can transmit in parallel. A number of data units may be aggregated into an aggregate frame to be transmitted by the second radio. The number of data units may be based on the scheduling message.

Abstract: A first wireless station provides a configuration indication value that specifies a maximum number of medium access control layer service data units (MSDUs) that may be included in each medium access control layer protocol data unit (MPDU), or in each aggregated MPDU (A-MPDU), received by the first wireless station. A second wireless station receives the configuration indication value from the first wireless station, and in response, transmits only MSDUs (or A-MSDUs) having no more than the specified maximum number of MSDUs to the first wireless station. The configuration indication value can be included in various elements transmitted between the first and second wireless stations, including for example, a high throughput (HT) capabilities element, a very high throughput (VHT) capabilities information field, a VHT operation element or an add block acknowledge (ADDBA) response frame.

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: Methods, systems, and devices are described for establishing a virtual communication link including at least a first and second physical link between two devices. A single virtual packet queue of a device may receive one or more data packets to be transmitted via the virtual communication link. The single virtual packet queue may attach a virtual sequence number to each of the one or more data packets and send the one or more data packets to one or more of the first or the second physical link according to the assigned virtual sequence numbers. The one or more packets may then be communicated via the first and/or second physical links according to link specific sequence numbers, such as medium access control (MAC) sequence numbers, assigned to the one or more data packets by the first and/or second physical links.
