Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information that indicates a transmit precoding matrix indicator, that identifies a precoding matrix, and a set of demodulation reference signal (DMRS) antenna ports. A first association may be between a first set of antenna indices of the precoding matrix, that form a first transmission group, and a first code-division multiplexing (CDM) group of the set of DMRS antenna ports, and a second association may be between a second set of antenna indices of the precoding matrix, that form a second transmission group, and a second CDM group of the set of DMRS antenna ports.

Abstract: Uplink control channel group and cross-carrier scheduling is disclosed for cooperative communications of a virtual UE. In an aspect, a UE reports a cooperative configuration with member UEs of a virtual UE and reports associations between a plurality of component carriers (CCs) allocated to a cell group and each member UE of the virtual UE. The UE may then receive an uplink control transmission configuration message dividing each member UE into an assigned uplink control transmission group and assign one or more component CCs into one or more CC sets, wherein each CC set is assigned to each uplink control transmission group. The UE may receive an uplink scheduling message from a serving base station, wherein the uplink scheduling message includes an uplink schedule for CCs within the CC set assigned to an uplink control transmission group associated with the UE. Other aspects and features are also claimed and described.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for beam identification for physical downlink control channel (PDCCH) repetition. Upon beam failure detection, a user equipment (UE) may identify candidate beams for re-establishing communications. The UE can use a set of channel state information reference signal (RS) resource configuration or synchronization signal/physical broadcast channel block indexes to determine a set of candidate beams. The set may include a list of a pair of RSs or indexes for serving cells that have radio link qualities below a threshold. The UE may report the candidate beams to a base station (BS) via a Media Access Control (MAC) Control Element (MAC-CE) or a physical random-access channel (PRACH) transmission. The BS may provide a configuration signal a resource set that includes a pair of RSs or indexes for serving cells with radio link qualities below the threshold.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for transmitting a channel state information (CSI) report from a user equipment (UE). The CSI report may be a UE initiated CSI report or may be based on a downlink grant. The UE may determine to transmit the CSI report based on measurement using a physical downlink control channel (PDSCH) and/or a demodulation reference signal (DMRS). The UE may determine a reference resource for CSI feedback. The UE may calculate a channel quality indicator (CQI) based on the reference resource. The UE may transmit the CQI in the CSI report on an uplink resource.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications system may support techniques for random access response (RAR) enhancements for multiple random access channel (RACH) procedures. In some cases, a user equipment (UE) may receive multiple physical downlink control channel (PDCCH) orders triggering respective RACH procedures, each PDCCH order indicating a preamble identifier associated with the respective RACH procedure. In some cases, the preamble identifiers may be the same or different. The UE may transmit a random access preamble corresponding to a preamble identifier indicated in a PDCCH order and may receive a random access response associated with a respective RACH procedure based at least in part on an indication included in the random access response. In some cases, the indication may be associated with a preamble identifier indication. In some other cases, the indication may be associated with a timing advance group.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink control information (DCI) message that includes a frequency domain resource allocation (FDRA). The FDRA may indicate a set of resource blocks (RBs), and the UE uses the indicated set of RBs to identify a first set of RBs for uplink communications using a first transmission configuration indicator (TCI) state and a second set of RBs for uplink communications using a second TCI state, both of which satisfy a threshold for performing transform precoding. The UE may transform precoding the first uplink signaling and the second uplink signaling based on the first and second sets of RBs satisfying the threshold for performing transform precoding.
