  • Patent number: 11108503
    Abstract: A first communication device receives an aggregated data unit from a second communication device. The aggregated data unit aggregates (i) one or more sets of multiple data units, each set of multiple data units to be acknowledged by a respective block acknowledgement and (ii) one or more single data units, each single data unit to be acknowledged by a respective single acknowledgement. The first communication device generates a block acknowledgment frame that includes (i) block acknowledgement information to acknowledge the one or more sets of multiple data units, and (ii) single acknowledgment information to acknowledge the one or more single data units, where the block acknowledgement frame omits an indication that the block acknowledgement frame includes the single acknowledgement information. The first communication device causes the block acknowledgement frame to be transmitted to the second communication device.

  • Patent number: 11063705
    Abstract: In a Non-Orthogonal Multiple Access (NOMA) system, a user equipment (UE) can be configured to transmit signals with multiple access (MA) signatures. If a base station configures multiple MA signatures to a UE, the UE can select one or more MA signatures, then transmit signals in parallel, serial, or in hybrid ways. Due to the flexibility and complexity of the UE selecting MA signatures without an explicit configuration from the base station, additional control overhead is provided to support parallel HARQ processing. In addition, a new DCI format is disclosed that supports multi-branch NOMA transmission, which allows multiple ACK/NACKs within a DCI. Further, using the techniques disclosed herein, a base station can explicitly indicate ACK-NACKs without being assisted by a HARQ ID field.

  • Patent number: 11051260
    Abstract: An electronic device, method, and computer program product provide an asynchronous quick connection or reconnection between wireless connecting devices for low-latency transitions in presentation of content to a user. A first device transmits an out-of-band frame sync signal to a second device to prompt the second device to synchronize clocks with the first device and to one of: (i) connect; and (ii) reconnect an over-the-air (OTA) communication session with the first device. First and second devices establish the OTA communication session. The establishment is expedited by the out-of-band frame sync signal. First device transmits output data, via the in-band OTA session, by the first device to the second device to present the output data on a second user output device of the second device.

  • Patent number: 11038719
    Abstract: Channel estimation performance depends on the amount of averaging performed by a channel impulse response coherent filter. For half-duplex UEs, which use a single phase locked loop (PLL) for both downlink transmissions and uplink transmissions, averaging may not be performed across downlink subframes before and after uplink subframes if the PLL's phase changes and locks to a random initial value when switching transmission directions. Techniques disclosed herein facilitate estimating the PLL's random initial phase and enable correcting the phase of symbols accordingly. By correcting the phase of the symbols, it is possible to average across symbols before and after a frequency re-tune and/or a transmission direction switch based on the phase correction. This may serve to improve the accuracy of channel estimation.
