  • Patent number: 11606234
    Abstract: Systems, apparatuses and methods described herein provide a method for padding a signal extension of orthogonal frequency-division multiplexing (OFDM) symbols. A transceiver may obtain a plurality of data symbols for transmission, and determine that a number of information bits for a last symbol of the plurality of data symbols is not an integer value. A special padding rule may be applied to add padding bits to the last symbol. A number of coded bits for the last symbol may be determined when the number of information bits for the last symbol has changed, and the plurality of data symbols for data transmission may be encoded based on the determined number of coded bits for the last symbol.

  • Publication number: 20220393838
    Abstract: A wireless user equipment (UE) may employ any of various mechanisms for reporting signal quality measurements to a wireless network. The UE may impose a time delay between measurement and reporting, based on a delay parameter K. The UE may average measurements obtained at different measurement instances. The UE may employ any of various schemes for prioritizing transmission of one type of report over another, when temporal collisions occur between different types of report. The UE may employ a differential report that includes a state for indicating that a beam is not workable. The UE may employ a beam index that includes a state for indicating an invalid beam. A base station may receive a signal quality report and determine workability of a beam, e.g., by triggering a report of channel state information.

The announcement frame indicates (i) an end time of the broadcast or multicast service period and (ii) an order of a sequence of frames to be directed to the multiple second wireless devices. Each of the sequence of frames is transmitted at the first wireless device using a directional antenna pattern to a respective one of the multiple second wireless devices, according to the order of the sequence of frames indicated in the announcement frame. An acknowledgement frame in response to the each of the sequence of frames is received at the first wireless device from the respective one of the multiple second wireless devices.

  • Publication number: 20220369123
    Abstract: Apparatuses, systems, and methods for beam reporting to facilitate multiple transmission and reception points, multi-TRPs, transmission schemes. A UE may receive, from a base station a configuration to report a beam quality based on at least one of a first reporting scheme and a second reporting scheme or a configuration of measurement resources for each TRP of a plurality of TRPs. The UE may report the beam quality based on the configuration or L1 measurements for multiple beam pairs and a recommended and/or assumed transmission scheme based on the configured measurement resources. The first reporting scheme may include the UE reporting at least one L1 measurement for multiple beams and the second reporting scheme may include the UE reporting at least one L1 measurement for multiple beam pairs. The recommended and/or assumed transmission scheme may be a non-coherent-joint transmission (NC-JT) transmission scheme and/or a single frequency network (SFN) transmission scheme.

  • Publication number: 20220360398
    Abstract: To reduce the beam reporting latency, a base station may include a sounding reference signal (SRS) indication to a wireless communication device (UE) as part of the transmission configuration information (TCI) transmitted to the UE, allowing the UE to receive a corresponding downlink signal using the same beam (or with the same beam) the UE used to transmit (or with which the UE transmitted) the SRS indicated in the TCI. The SRS may be one of multiple SRSs previously transmitted by the UE. The UE may transmit the multiple SRSs periodically and/or according to semi-persistent scheduling, or it may transmit them aperiodically. Therefore, the UE does not need to report the beam quality, and the base station may perform the necessary beam measurement(s) instead. Various parameters and conditions may be defined for the UE to support SRS-based TCI.

  • Publication number: 20220322247
    Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for triggering a change in beam configuration based on UL beam conditions. The UE may detect an unsafe UL beam condition for an UL beam based, at least in part, on an MPE level being exceeded by the UL beam. In response to the detection, remedial actions that to alleviate the unsafe UL beam condition may be performed. The remedial actions may prioritize UL beam quality over DL beam quality and may include reducing a transmit power of the UL beam based on an MPR, triggering an intra-panel antenna switch to a candidate UL beam that satisfies one or more conditions for intra-panel beam switching, triggering an inter-panel antenna switch to a candidate UL beam that satisfies one or more conditions for intra-panel beam switching, and/or signaling a beam failure to a network serving the UE.

  • Patent number: 11463908
    Abstract: Some embodiments described herein provide a method for transmitting a preamble in accordance with a wireless local area network communication protocol. In some embodiments, a data frame may be obtained for transmission including a preamble compliant with the wireless local area network communication protocol. It may be determined that the preamble includes a first preamble portion that spans multiple symbol durations and a second preamble portion that spans a single symbol duration. The first preamble portion via beamforming may be transmitted based on a first beamforming matrix. When a transmission mode of the second preamble portion is beamforming, a second beamforming matrix may be generated based on the first beamforming matrix, each tone for the second preamble portion may be calculated based on the second beamforming matrix. Each calculated tone may be transmitted in accordance with the wireless local area network communication protocol.

  • Patent number: 11463903
    Abstract: A method for transmitting a resource request for an uplink (UL) multi-user (MU) transmission is described. A High Throughput (HT) Control field that includes buffer information corresponding to media access control (MAC) protocol data units (MPDUs) that are queued for transmission by a first communication device is generated by the first communication device. The buffer information indicates a number of bytes for the MPDUs that are queued for transmission. A resource request MPDU that includes the HT Control field is generated by the first communication device. The resource request MPDU is transmitted by the first communication device to a second communication device via a wireless communication channel to request an allocation of radio resources for the UL MU transmission by the second communication device.
