  • Patent number: 11018742
    Abstract: Methods, systems, and devices for wireless communications are described that provide for identification of beamforming parameters for a downlink transmission beam based at least in part on a set of rules that define a priority order for control transmission and data transmissions. Downlink resources may be allocated to a user equipment (UE) for a downlink transmission via a first set of downlink beamforming parameters, and the UE may also be configured to monitor a control resource set using a different set of downlink beamforming parameters within a same transmission time interval (TTI) as the downlink transmission. A UE and a base station may identify which beamforming parameters to use for the downlink transmission based on the priority order. The set of rules may define which set of downlink beamforming parameters are to be used, whether the downlink transmission is rate-matched around the control resource set, or combinations thereof.
