  • Publication number: 20210282145
    Abstract: Wireless communication devices, systems, and methods relate to selecting transmission parameters that optimize a dimension (e.g., time, frequency, and/or spatial) under a set of constraints. A UE may receive a resource allocation mode indication and a traffic parameter indication from a BS. The resource allocation mode indication informs the UE to optimize along a time dimension, a frequency dimension, and/or a spatial domain. The traffic parameter indication informs the UE what constraints to consider for the transmission parameters. The UE may use this information upon receipt of a reference signal in selecting transmission parameters based on the received reference signal, resource allocation mode indication, and traffic parameter indication. The resource allocation mode may correspond to optimization within a single slot or across multiple slots. Once selected, the UE may transmit the transmission parameters to the BS for use in sending the message to the UE.

  • Publication number: 20210274520
    Abstract: In some aspects, multi-slot transport block (TB) configurations for communicating data between wireless devices, such as between a base station and a user equipment (UE), in a wireless communication system are described. Some examples of multi-slot configurations enable the communication of large payloads. For example, an application of a wireless device may jointly process data from a large file or other large set of packets. In such examples, the wireless device transmitting the large file may utilize a multi-slot TB including multiple TB segments corresponding to respective slots of a transmission. Similarly, a wireless device receiving the large file may utilize the multi-slot TB configuration for receiving the data.

  • Publication number: 20210266787
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform a measurement operation to attain multiple measurements to report to a base station. The measurements may correspond to a first number of bits if reported. The UE may compress the measurements using an encoder neural network (NN) to obtain an encoder output indicating the measurements. This encoder output may include a second number of bits that is less than the first number of bits. The UE may report the encoder output to the base station in this compressed form. At the base station, the encoder output may be decompressed according to a decoder NN. Once the base station decompresses the encoder output, the UE and base station may communicate according to the measurements determined from the decompression. In some cases, the base station may perform load redistribution based on the measurements.

  • Publication number: 20210266950
    Abstract: Methods, systems, and devices for wireless communications are described. A first device and a second device may communicate via a channel. The first device may generate and transmit a reference signal, which may be a distortion probing reference signal with a high peak to average power ratio. In one implementation, the first device may use the reference signal as an input for a neural network model to learn a nonlinear response of the second device transmission components. In another implementation, the second device may sample the generated reference signal, and use the samples as inputs for a neural network model to learn the nonlinear response. The first device and the second device may exchange signaling based on learning the nonlinear response, and each device may compensate for the nonlinear response when communicating via the channel.

Relay circuitry tests data throughputs over a Fifth Generation New Radio (5GNR) network Transceiver (XCVR), Long Term Evolution (LTE) network XCVR, and wireline network XCVR. The relay circuitry selects sets of network XCVRs for the user XCVRs based on the data throughput testing. The relay circuitry indicates the selected network XCVRs to the user XCVRs. The user XCVRs wirelessly exchange user data with the wireless UEs and exchange the user data with the selected network XCVRs. The selected network XCVRs exchange the user data with one or more data communication networks.

  • Patent number: 11076409
    Abstract: Techniques are described herein for allocating transmit power between precoding resource groups (PRGs) and/or transmit chains of a user equipment (UE) to reduce the amount of total transmit power that is unused. The UE may determine a set of precoding scaling factors for each PRG to efficiently allocate a total transmit power between the PRGs using a two-stage approach. During a first stage, the UE may determine PRG-specific precoding scaling factors for each PRG associated with an uplink transmission. During a second stage, the UE may determine a residual precoding scaling factor to apply to all the PRGs associated with the uplink transmission and determine overall precoding scaling factors for each PRG. The second stage may be configured to refine the scaling factors determined in the first stage such that at least some of the unused transmit power is allocated to at least one of the PRGs or transmit chains.
