Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for wireless communications. In one aspect, a user equipment (UE) may receive, from a base station, a configuration message indicating a first beam associated with an uplink control transmission and downlink control information (DCI) indicating a second beam associated with the uplink data transmission. The UE may select the first beam or the second beam based on an overlap in time between the uplink control transmission and the uplink data transmission. The base station may identify the first beam or the second beam based on the overlap between the uplink control transmission and the uplink data transmission. The UE may transmit, and a base station may receive, at least a portion of the uplink control transmission and at least a portion of the uplink data transmission using the selected first beam or second beam.

Abstract: This disclosure provides systems, methods, and apparatuses for updating a joint downlink and uplink transmission configuration indicator (TCI) state for a communication channel or a reference signal. In one aspect, abase station (BS) may indicate, to a user equipment (UE), a joint downlink and uplink TCI state for a communication channel or a reference signal. The BS may indicate a usage, transmission types, or transmission resources associated with the joint downlink and uplink TCI state. Accordingly, the UE may associate the joint downlink and uplink TCI state with a channel or reference signal, as indicated by the BS. This enables to the UE to utilize a common beam indicated by the joint downlink and uplink TCI state. As a result, the UE and the BS may reduce signaling and network overhead by using a single TCI to indicate properties of a common beam for both downlink and uplink.

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 receive a downlink grant scheduling a physical downlink shared channel (PDSCH) and a demodulation reference signal (DMRS). The UE may determine to report a CSI in response to a measurement of a downlink measurement resource or in response to the downlink grant requesting the CSI. The UE may determine a reserved uplink resource on which to report the CSI. The UE may transmit a CSI report on the reserved uplink resource.

Abstract: In inter-cell mobility, the association between the CORESET and the TRP may be dynamically updated by L1/L2 beam switch signaling, which may cause RRC reconfiguration latency. To address the latency issue, a UE, in one aspect of the disclosure: (1) receives, from a cell, a configuration of a CORESET and a configuration of a set of TRPs; (2) receives, from the cell, an index indication of an index for the CORESET; and (3) determines, based on the index indication, a TRP in the set of TPRs to be associated with the CORESET.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that a multi-panel uplink transmission is to be performed by the UE, the multi-panel uplink transmission using at least a first transmit panel and a second transmit panel of the UE. The UE may identify a priority order for performing uplink transmissions of the multi-panel uplink transmission from the UE, the priority order including priority levels associated with the first transmit panel and the second transmit panel. The UE may identify an available transmit power for the multi-panel uplink transmission. The UE may perform, according to the priority order, the multi-panel uplink transmission using at least the first transmit panel at a first transmit power and the second transmit panel at a second transmit power, the first transmit power and the second transmit power based at least in part on the available transmit power.

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 control channel (PUCCH) transmitted on a first antenna panel of the UE is to overlap with a physical uplink shared channel (PUSCH) transmitted on a second antenna panel of the UE based at least in part on downlink control information (DCI) scheduling the PUCCH and the PUSCH. The UE may determine to transmit uplink control information (UCI) on one or more of the PUCCH or the PUSCH based at least in part on determining that the PUCCH is to overlap with the PUSCH, and transmit the UCI on one or more of the PUCCH or the PUSCH based at least in part on determining to transmit the UCI on one or more of the PUCCH or the PUSCH. Numerous other aspects are provided.

Abstract: A user equipment for wireless communication is provided. The user equipment receives configuration information for a serving cell. The configuration information indicates at least one bandwidth part and at least two timing advance group identifiers for the serving cell. The user equipment determines whether the at least one bandwidth part is configured to support uplink transmissions from a plurality of antenna panels of the user equipment. The user equipment performs a first uplink transmission from a first antenna panel of the plurality of antenna panels based on a first timing advance group identifier and a second uplink transmission from a second antenna panel of the plurality of antenna panels based on a second timing advance group identifier when the at least one bandwidth part is configured to support the uplink transmissions from the plurality of antenna panels.

Abstract: Aspects enable a user equipment (UE) to provide group-based beam reporting for multiple groups of beams. The UE measures a signal for each of a plurality of beams, wherein the plurality of beams are grouped into multiple groups of more than one beam that are capable of simultaneous operation. The UE transmits a channel state information (CSI) report comprising a group-based beam report for each of the multiple groups of more than one beam. Each group-based beam report comprised in the CSI report may indicate a beam metric for each beam of the more than one beam in a corresponding group. Each group-based beam report comprised in the CSI report may indicate a group beam metric for the one or more beams comprised in a corresponding group. A base station may configure the UE for the group-based beam reporting for multiple groups of more than one beam.
