  • Patent number: 11057166
    Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify time and frequency resources for a physical downlink shared channel (PDSCH) to be transmitted to a user equipment (UE) in a first transmission time interval (TTI). The base station may transmit configuration information for a control channel search space set in a second TTI. The second TTI may precede the first TTI. The configuration information may include an indication of an absence of a physical downlink control channel (PDCCH) transmission to send in the control channel search space set indicating the identified time and frequency resources for the PDSCH, and a set of time and frequency resources for the control channel search space set. The UE may receive the configuration information and identify the time and frequency resources allocated for the PDSCH in the second TTI, and receive the PDSCH transmission in the second TTI.

  • Patent number: 11051324
    Abstract: Aspects of the present disclosure provide mechanisms for utilizing a single uplink grant to transmit scheduling requests (SRs) for two or more logical channels. A base station may allocate a separate grant of uplink resources for each SR opportunity (e.g., each logical channel for which a user equipment (UE) may transmit a SR to the base station). When the allocated uplink resources are within the same time period, the UE may select a subset of the SR opportunities for which to transmit a SR and partition the subset into one or more groups of SR opportunities. The UE may then generate one or more SR bits representing the one or more groups of SR opportunities and transmit the one or more SR bits on the single uplink grant.

  • Patent number: 11051175
    Abstract: Methods, systems, and devices for wireless communication are described. The described techniques provide for transmission of uplink data from a user equipment (UE) in the absence of scheduled uplink resources for the uplink data transmission that are allocated to the UE prior to the transmission of the uplink data. Various examples provide uplink configurations that may be used for unscheduled uplink transmissions of a UE, which may be selected dynamically or semi-statically. Unscheduled uplink transmissions may be transmitted in shared radio frequency spectrum according to one or more frame structures, and access to the shared radio frequency spectrum may be determined based on a priority of an operator associated with a UE for accessing the spectrum. Beamforming techniques may be used for transmissions and beam widths may be selected based on the information in a transmission, an operator priority for use of shared radio frequency spectrum, or any combination thereof.
