Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a configuration to perform multi-panel communications with a base station using a first panel and a second panel of the UE. The base station may transmit indications of a first slot format and a second slot format for the first panel and the second panel for a time period, at least one symbol for the first slot format having a different communication direction than for the second slot format. The base station may indicate the slot formats in a common configuration and a dedicated configuration for the first panel and the second panel. Additionally or alternatively, the base station may indicate the slot formats in a corresponding downlink control information (DCI) message. The UE and the base station may communicate using the first panel and second panel according to the corresponding slot format.

Abstract: This disclosure provides systems, methods and apparatuses for transmitting and receiving a transmission configuration indicator (TCI) for a joint downlink/uplink beam. A base station (BS) may transmit the TCI that indicates one or more reference signals providing a user equipment (UE) with properties for the beam used by the UE to transmit data or control information on an uplink as well as used by the UE to receive data or control information on a downlink. Accordingly, the UE and the BS may reduce signaling and network overhead by using a single TCI to indicate quasi-co-location (QCL) rules for both uplink and downlink.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, for example a user equipment (UE), may determine that one or more resource elements associated with a phase-tracking reference signal (PRTS) transmission on a first scheduled physical uplink shared channel (PUSCH) are multiplexed with one or more resource elements associated with a data transmission on a second scheduled PUSCH. The UE may puncture the one or more resource elements associated with the data transmission on the second scheduled PUSCH and transmit the PTRS transmission on the first scheduled PUSCH based on puncturing the one or more resource elements associated with the data transmission on the second scheduled PUSCH. Alternatively, the UE may rate match the one or more resources associated with the PTRS transmission around one or more additional resources and transmit the PTRS transmission on the scheduled first PUSCH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive at least one downlink control information message that schedules multiple sets of repetitions of a physical uplink shared channel transmission with different sets of transmission parameters. The scheduled repetitions of the multiple sets of repetitions may be transmitted consecutively. The UE may transmit one or more of the scheduled repetitions of the multiple sets of repetitions using one or more time gaps between the scheduled repetitions of the multiple sets of repetitions. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station as part of a wireless communications system. The UE may receive, from a base station, an indication of a configuration for a multi-panel transmission power control (TPC) command to be transmitted by the base station. The UE may also receive, according to the indicated configuration, a downlink control information (DCI) message including a set of TPC commands. The UE may determine, based on the set of TPC commands, a first transmit power for a first antenna panel of the UE and a second transmit power for a second antenna panel of the UE. The UE may transmit an uplink signal using the first antenna panel at the first transmit power and the second antenna panel at the second transmit power.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for a user equipment (UE) and a base station (BS) to determine channel state information (CSI) processing unit (CPU) occupancy of the UE. The UE and the BS may determine that at least one CPU from a CPU pool is occupied by an uplink CSI request from a CSI reference signal (CSI-RS) to at least a CSI request occasion. The UE and the BS may determine a number of occupied CPUs, for example, based on an accumulated or aggregated number of occupied CPUs for multiple CSI operations. The UE may perform a number of CSI operations based on the determined number of occupied CPUs. The BS may configure the UE to perform the number of CSI operations, for example, by transmitting one or more of a configuration, activation, or scheduling message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a physical uplink shared channel (PUSCH) resource for reporting one or more first channel state information (CSI) reports overlaps with a physical uplink control channel (PUCCH) resource for reporting one or more second CSI reports. The UE may transmit the one or more first CSI reports multiplexed with at least a portion of the one or more second CSI reports in uplink control information in the PUSCH resource. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to indicate to a base station a distribution of transmit antennas and receive antennas across a set of antenna panels, and the base station may configure resource sets for reference signal transmissions from the antenna panels based on the indicated distribution. In a first example, the UE may be configured to indicate a respective number of transmit antennas and receive antennas at each antenna panel. In a second example, the UE may be configured to indicate a sum of transmit antennas and a sum of receive antennas across all antenna panels, along with information on how the transmit antennas and receive antennas are distributed. Based on the indication, the base station may configure resource sets for reference signal transmission on sets of ports in resources of the resource sets.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may support simultaneous transmissions of data on an uplink shared channel that is associated with a first cell, and control information such as uplink control information on an uplink control channel associated with a second cell. The UE may receive scheduling information that indicates a time domain overlap of scheduled transmissions associated with the uplink control channel and the uplink shared channel, and a multiplexing configuration for the UE which indicates whether the UE is to multiplex the uplink control information on the uplink control channel or whether the UE is to multiplex the uplink control information on the uplink shared channel.
