Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a user equipment (UE) may support two or more uplink switching periods for transmit chain switching. The UE may transmit a UE capability message indicating the UE capability to support a first uplink switching period and a second uplink switching period for transmit chain switching. The first uplink switching period and the second uplink switching period may each correspond to different switching periods associated with configuration switches between different transmit chain configurations of the UE. The UE and a base station may select an uplink switching period from among the first uplink switching period and the second uplink switching period. The UE may transmit an uplink data message to the base station after a preparation time that is based on the uplink switching period.

Abstract: A method for wireless communication at a UE and related apparatus are provided. In the method, the UE first transmits, to a network entity, RF information indicating coupling states of multiple bands of the UE based on an RF exposure of the multiple bands. The UE then communicates, after providing the RF information indicating the coupling states, with the network entity through one or more of the multiple bands.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a maximum transmission power for an uplink transmission on a first cell of a first cell group (CG) based on a direction of communications (e.g., uplink, downlink, or flexible) with a separate cell of a second CG during a same duration of the uplink transmission and within a same first frequency range, where the direction of communications is either an actual direction or an assumed direction. The UE may receive an uplink grant scheduling the uplink transmission during a symbol and within the first frequency range, determine the maximum transmission power for the UE based on the direction of communications for the separate cell during the symbol and within the first frequency range, and subsequently transmit the uplink transmission in accordance with the maximum transmission power.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit capability information indicating a capability of the UE to receive multicast communications while operating in an inactive state. The UE may receive, from a first cell, configuration information that indicates a common frequency resource (CFR) associated with receiving multicast communications from the first cell while operating in the inactive state. The UE may receive, from the first cell, multicast mobility information associated with receiving multicast communications from one or more neighboring cells while operating in the inactive state. The UE may receive, while operating in the inactive state, one or more multicast communications from at least one of the first cell or a second cell based at least in part on at least one of the configuration information or the multicast mobility information. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor a configured set of control channel elements (CCEs) for physical downlink control channel (PDCCH) decoding for a scheduled cell of a set of scheduled cells, wherein the configured set of CCEs is on a per scheduled cell basis or a per carrier indicator field value basis. The UE may decode downlink control information (DCI) in one or more CCEs of the monitored configured set of CCEs. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques may provide for handling of priority indications in scenarios where simultaneous physical uplink control channel (PUCCH)-physical uplink shared channel (PUSCH) is supported. For example, wireless communications systems may configure (e.g., via radio resource control (RRC) signaling) simultaneous PUCCH-PUSCH across two or more carriers, where piggybacking of feedback information on uplink shared channel transmission may be disabled. Further, a grant (e.g., downlink control information (DCI) scheduling a PUSCH transmission) may include a priority index field to indicate a priority associated with a transmission or resources scheduled by the grant. The described techniques may provide for efficient handling of priority indications associated with scheduled transmissions that overlap when simultaneous PUCCH-PUSCH is supported (e.g., techniques are provided for performing or dropping scheduled transmissions that overlap when simultaneous PUCCH-PUSCH is enabled based on any priority indications associated with the overlapping scheduled transmissions).

Abstract: Apparatus, methods, and computer program products for wireless communication are provided. An example method may include receiving a radio resource control (RRC) communication from a second network node, where the RRC communication configures a set of cell-specific reference signal (CRS) resource elements (REs). The method may further include receiving a demodulation reference signal (DM-RS) configuration from the second network node, the DM-RS configuration configures a set of DM-RS REs associated with a PDCCH. A first subset of DM-RS REs in the set of DM-RS REs may overlap with the set of CRS REs in a time domain and a frequency domain. The method may further include communicating with the second network node based on one or more DM-RS REs in the set of DM-RS REs associated with the PDCCH, where the first subset of DM-RS REs is excluded from the one or more DM-RS REs.
