摘要： Methods, systems, and devices are described for eliminating interference from a convoluted signal comprising several signals of different radio access technologies (RATs), such as a Long Term Evolution (LTE) signal and wireless local area network (WLAN) signal, in an unlicensed or shared radio frequency spectrum band are described. In accordance with the present disclosure, a dual-radio mobile device may utilize a multiple radios to assist in the operation of interference cancellation. Specifically, in some examples, a first radio (e.g., WLAN radio) may process the received convoluted signal to reconstruct a first signal (e.g., WLAN signal). The reconstructed first signal may be utilized by a second radio (e.g., LTE radio) to identify a second signal (e.g., LTE signal) in the received convoluted signal by cancelling or removing the reconstructed first signal from the convoluted signal.

摘要： Methods, systems, and devices are described for wireless communication. A wireless device may identify an upcoming interference period, determine a receive end time based on when the interference period will begin to disrupt incoming messages, and transmit a scheduling outlook message to a transmitter to schedule around the interference in response to receiving a packet (request-to-send (RTS) or data). The wireless device may hash a receiver address (RA) associated with the packet exchange message such as a clear-to-send message or a block acknowledgement to make room for the scheduling outlook message. An example scheduling outlook field (in the place of the full RA field) may include a shortened RA, a number of supported spatial streams, a supported bandwidth, a set of tone allocation units (TAUs), a receive end time (or receive duration), and an interference level.

摘要： Various embodiments enable a multi-active mobile communication device to mitigate (manage) interference by a frequency band used by a first subscription with the frequency band used by a second subscription. The device processor may generate modified power measurements for one or more frequency bands of a first subscription and use the modified power measurement(s) to cause the first subscription to switch from the frequency band that interferes with the frequency band of the second subscription. The modified power measurement may be a decreased power measurement of the first frequency band and/or an increased power measurement of a second frequency band that does not interfere with the frequency band of the second subscription. As a result, various embodiments may mitigate or otherwise manage the impact of coexistence interference between the first and second subscriptions of a multi-active mobile communication device without limiting capabilities of the device or changes to the network.

摘要： 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.

摘要： The use of multiple radios using different radio access technologies (RATs) on a wireless station can result in interference that can be mitigated by reducing, on a packet-by-packet basis, the bandwidths of communications using one of the RATs. For example, the bandwidth of wireless local area network (WLAN) communications sent or received by a wireless station can be reduced in order to avoid interference with Long-term Evolution (LTE) or LTE-Advanced (LTE-A) communications. A wireless station can determine that only a portion of an interfering bandwidth used by a first radio will interfere with the receipt of communications on a second radio, then the wireless station can dynamically adjust its transmissions on the first radio to only use non-interfering frequencies.

摘要： Methods, systems, and devices are described for power conservation in a wireless communications system through efficient transmissions and acknowledgements of information between an AP and a station. The time between a determination by a station to enter a power saving mode and entering network sleep mode by the station may be reduced through a transmission, by an AP, of an MPDU to the station successive to an SIFS after transmission of an acknowledgement to the station of a PS-Poll frame from the station. The time to enter a power saving mode by a station may also be reduced through transmission of A-MPDUs in which a last MPDU of the A-MPDU has an indicator bit cleared to indicate no additional data is to be transmitted. An AP may prevent a retransmission of an MPDU to the station in the absence of an acknowledgement from the station, to further enhance efficiency.
