Abstract: Aspects of the present disclosure relate to cross-component carrier (CC) activation of joint downlink (DL)/uplink (UL) transmission configuration indicator (TCI) states. In one aspect, the apparatus receives, from a base station, an activation of a joint DL and UL TCI state for a CC, the joint DL and UL TCI state indicating a common beam for communication in DL and UL. The apparatus applies the joint DL and UL TCI state to multiple CCs in response to receiving the activation of the joint DL and UL TCI state for the CC.

Abstract: Aspects presented herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a TRP or base station. In one aspect, the apparatus may receive, from a TRP, a MAC-CE activating a subset of configured joint DL and UL TCI states, each activated joint DL and UL TCI state indicating a common beam for communication in DL and UL, the MAC-CE indicating a CORESET pool ID associated with a set of CORESETs. Additionally, the apparatus may communicate with the TRP through DL and UL scheduled through one or more CORESETs of the set of CORESETs associated with the CORESET pool ID based on the activated joint DL and UL TCI states.

Abstract: This disclosure provides methods, devices, and systems for resource selection supporting the identification of resources for receiving two-stage downlink control information (DCI). In some systems, for example, a base station may transmit a first stage DCI and a second stage DCI to a user equipment. The first stage DCI may include control information for a group of UEs including the UE and the second stage DCI may include control information that is specific to the UE. The UE may determine a resource to use for receiving the second stage DCI based on an indication in the first stage DCI. In some examples, the UE may determine a resource from a resource pool based on a resource selector included in the first stage DCI and receive the second stage DCI over the determined resource. The resource pool may be indicated by the first stage DCI or pre-configured at the UE.

Abstract: Certain aspects of the present disclosure provide techniques for differential power parameter reporting in multi-panel uplink transmission. A method that may be performed by a user equipment (UE) includes determining a first transmit power control parameter associated with a first panel of the UE and a differential transmit power control parameter to be used to indicate a second transmit power control parameter associated with a second panel of the UE, the differential transmit power control parameter indicating a difference between the first transmit power control parameter and the second transmit power control parameter generating a reporting message indicating the first transmit power control parameter and the differential transmit power control parameter; and transmitting the reporting message to a base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify respective transmission/reception point (TRP) index values corresponding to a first TRP and a second TRP, where the UE may be configured for at least a first transmission of an uplink signal to the first TRP using a first antenna panel and a second transmission of the uplink signal to the second TRP using a second antenna panel. The UE may determine default pathloss reference signal (PLRS) resources for one or more PLRSs that are associated with the first transmission and the second transmission of the uplink signal. In some cases, the default PLRS resources may be determined based on a whether PLRSs are configured for the UE, the respective TRP index values, and a resource selection rule. The UE may transmit the one or more PLRSs using the default PLRS resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink control information (DCI) message that includes a first field indicating a first transmit precoder matrix indicator (TPMI) index and a quantity of transmission layers and a second field indicating a second TPMI index. The UE may determine a first precoding matrix for transmitting a first set of repetitions of a physical uplink shared channel (PUSCH) transmission based at least in part on the first TPMI index and the quantity of transmission layers, and a second precoding matrix for transmitting a second set of repetitions of the PUSCH transmission based at least in part on the second TPMI index and the quantity of transmission layers. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as a user equipment (UE) may determine a set of repetitions of a first uplink data channel associated with a first directional beam and a set of repetitions of a second uplink data channel associated with a second directional beam different from the first directional beam. The UE may multiplex an uplink transmission associated with an uplink control channel with one or both of the first uplink data channel and the second uplink data channel, based on the set of repetitions of the first uplink data channel and the set of repetitions of the second uplink data channel As a result, the UE may transmit the multiplexed uplink transmission on one or both of the first uplink data channel and the second uplink data channel.

Abstract: Aspects of the disclosure relate to wireless communication systems that support multi-panel uplink transmissions. Transmission power control (TPC) commands are conveyed in a group common downlink control information (DCI) to support the multi-panel uplink transmissions. Additionally, the DCI can explicitly indicate which uplink panel TPC commands are associated with a particular panel through an explicit panel identification in the DCI, radio resource control (RRC) configuring TPC blocks in a DCI for a particular cell, or by two DCIs in respective search spaces where the TPC in each respective DCI are associated with a corresponding uplink panel transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine one or more of a default uplink beam or a default pathloss reference signal (PL RS) for a first component carrier of a communication link; and apply the one or more of the default uplink beam or the default PL RS to a second component carrier of the communication link based at least in part on the UE not receiving an indication of a spatial relation for the second component carrier or an indication of a PL RS for the second component carrier. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for handling maximum permissible exposure (MPE) events. In some cases, upon detecting an MPE event, a UE may provide assistance information that a base station may use to adjust uplink scheduling in an effort to reduce impact of the MPE event.
