  • Patent number: 11026183
    Abstract: Aspects of the present disclosure provide techniques for a user equipment (UE) to set uplink power control for a long uplink burst and a short uplink burst. The UE receives uplink power control information including a first set of power control parameters for a long uplink burst and a second set of power control parameters for a short uplink burst with the sets of power control parameters being different from each other. The UE configures uplink power control for the long uplink burst based at least on the first set of power control parameters and the short uplink burst based at least on the second set of power control parameters. The UE sends at least one of a long uplink burst and a short uplink burst based on the corresponding uplink power control and sends at least one uplink power-headroom report for the long uplink burst and short uplink burst.

  • Patent number: 11025309
    Abstract: Aspects of the present disclosure provide methods and apparatus for selecting beamforming parameters for uplink transmissions based on an uplink reference signal. An example method generally includes identifying one or more parameters for beamformed transmission to a transmit receive point (TRP), transmitting a reference signal using beamforming in accordance with the identified parameters, and receiving, from the TRP in response to the reference signal, signaling for adjusting the one or more parameters for one or more subsequent beamformed transmissions.

  • Publication number: 20210152320
    Abstract: Wireless communications systems and methods related to full-duplex cooperative communication by a first device tethered with a second device communicating with a third device. With the tether, one device between the first device and the second device is designated or selected as a transmitter, and the other device as a receiver. In full-duplex operation, the transmitter may transmit outgoing data concurrent to the receiver receiving incoming data. In an example, one of the first and second devices may have a modem that is used to control the full-duplex communication. The modem controls both transmission and reception. In another example, both devices may have a modem. Each modem may assume responsibility for part of the full-duplex communication by performing some processing before either shipping received data, or transmitting outgoing data. The amount of processing may be split at a link layer. Interference cancellation may mitigate interference from full-duplex operation.

  • Publication number: 20210144648
    Abstract: Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas associated with different power classes. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. The local and auxiliary antennas may be associated with different power classes, and the first device may transmit a message to a base station indicating that the first device is capable of transmitting using antennas associated with different power classes. The first device may then receive configurations from a base station of different transmit powers to transmit on the antennas associated with the different power classes, and the first device may transmit uplink signals to the base station in accordance with the different transmit power configurations.

  • Publication number: 20210135717
    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for efficiently transmitting uplink signals to a base station using shared antennas. A first device may be in communications with a base station using local antennas and may identify a second device having auxiliary antennas available for transmitting uplink signals to the base station. Because the local antennas and auxiliary antennas may have different capabilities (e.g., due to different power or other constraints), the first device may generate first uplink signals for transmission using the local antennas differently from second uplink signals for transmission using the auxiliary antennas. The first device may transmit the first uplink signals to the base station using the local antennas and transmit the second uplink signals to the second device for transmission to the base station using the auxiliary antennas based on different configurations.

  • Publication number: 20210083735
    Abstract: Aspects of the present disclosure disclose various methods for grouping network resources into precoder resource groups (PRGs) for precoding in MIMO communication. A user equipment (UE) may select a common precoder that may not be restricted to a codebook for precoding the resources in the same PRG. These resource grouping methods provide the UE with the flexibility to select a precoder that is well suited to the channel or bandwidth. Moreover, the base station may reduce downlink signaling because it does not need to signal the precoder choice to the UE. In some examples, the base station may receive PRG based channel state information feedback that facilitates DL precoding. Other aspects, embodiments, and features are also claimed and described.

  • Patent number: 10951283
    Abstract: Methods, systems, and devices for wireless communications are described. In some cases, a user equipment (UE) may use multiple antenna ports to communicate with multiple transmission/reception points (TRPs), and each antenna port may correspond to a spatial dimension along which wireless communications may be transmitted. The UE may transmit a first sounding reference signal (SRS) to a serving TRP to aid the serving TRP in determining a subset of spatial dimensions available to the UE along which to transmit downlink transmissions. Upon receiving a downlink transmission from the serving TRP along the subset of spatial dimensions as determined by the serving TRP, the UE may transmit a second SRS to a neighboring TRP to indicate the subset of spatial dimensions. The neighboring TRP avoid transmitting downlink transmissions to the UE or to other UEs along the subset of spatial dimensions, thereby mitigating interference along the subset of spatial dimensions.

    Abstract: Methods, systems, and devices for wireless communications are described for identifying a file having a set of packets that are configured to be processed together. The base station may determine a segmentation scheme for the file based on a size of the file and identify a batch of assignments for communicating the file via a batch of transmissions based on the segmentation scheme. The base station may communicate the file via the batch of transmissions with a user equipment (UE) during the batch of assignments. Additional techniques are described herein for a UE to identify that the UE is storing a file in a buffer at the UE. The UE may transmit an indication to the base station that the buffer includes the file. In some cases, the UE may indicate a size of the file.
