Abstract: Methods, systems, and devices for wireless communications are described that provide for receive chain selection at a user equipment (UE) with efficient switching between a reduced number of receive chains and an increased number of receive chains for downlink communications based on conditions at the UE. A UE may adaptively adjust the number of active receive chains based on downlink grant activity, channel conditions, network parameters, or any combinations thereof. An estimator block at the UE may determine to adjust the number of receive chains based on a number of downlink grants within one or more time periods. In some cases, grants for an amount of data that exceeds a threshold may be qualified in order to be counted at the estimation block. Further, a transient state may be provided where the UE may maintain a higher number of active receive chains until UE feedback is provided.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication and more particularly, to techniques for bandwidth part adaptation for extended reality (XR) power saving. A method that may be performed by a UE generally includes receiving a first configuration of a first bandwidth part (BWP) and a second configuration of a second BWP, wherein the first BWP is configured for a lower traffic rate and the second BWP is configured for a higher traffic rate; obtaining an indication to switch from the first BWP to the second BWP; and switching from the first BWP to the second BWP in response to obtaining the indication.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station on multiple component carriers (CCs) in a carrier aggregation (CA) configuration. The base station may transmit an indication to the UE that identifies a new power mode (e.g., a power mode adjustment) that the UE is to implement. The power mode may identify communication parameters that the UE is to adjust. The UE may determine a delay for applying the new power mode on the CCs. The delay may provide the UE time to activate or deactivate components or elements based on the new power mode. In some examples, the UE may determine the delay based on one or more selected CCs and then apply the delay across the CCs. The UE may implement the power mode on one or more (or all) of the CCs following the delay.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may receive, from a base station, an indication of a set of component carriers (CCs) for the UE and a respective frequency range (FR) for each CC of the set of CCs. Each CC-FR pairing may be associated with a respective priority of a set of priorities. The UE may initiate a plurality of timers, where each timer of the plurality of timers may correspond to a respective CC-FR pairing. After expiration of a timer of the plurality of timers, the UE may measure one or more reference signals of a subset of the set of CCs based at least in part on a capability of the UE and a priority of the respective CC-FR pairing associated with the timer.

Abstract: Methods, systems, and devices for wireless communications are described that provide for power control for dual connectivity. A UE may identify a power control configuration that determines priorities for uplink transmissions over multiple component carriers and one or more base stations. The UE may identify a union of semi-static uplink or flexible transmissions between multiple component carriers employed by one cell group, such as a master cell group and a secondary cell group, and determine a configured power level for the cell group. The UE may then determine whether to transmit an uplink transmission on a cell of another cell group, based on the power control configuration and the configured power level.

Abstract: Methods, systems, and devices for wireless communications are described. One method may include transmitting a first signal instructing a user equipment (UE) to transition a state of a secondary cell associated with the UE; determining an allocation of resources for the UE to communicate with the secondary cell; and transmitting a second signal including an indication of an active bandwidth part (BWP) used for the allocation of resources based on the determining. The active BWP and the first signal may indicate the transition of the state of the secondary cell.

Abstract: Methods, systems, and devices for wireless communications are described Techniques described may be utilized to avoid errors caused by resource allocation calculations, which may be indicated via higher layer signaling and/or determined within DCI. A base station may transmit downlink control information indicating resource allocation types to avoid errors. In other cases, the UE and/or base station may designate a particular resource block group size to avoid the potential errors. The UE and/or base station may calculate a number of resource blocks groups for a bandwidth part and allocate the size of the resource block group based on the calculation. The UE and/or base station may conduct a comparison between a bandwidth part size and a resource block group size to determine whether to designate a different resource block group size to avoid the errors. Similar techniques may be utilized in allocating resources for precoding resource block groups.
