Abstract: Methods, systems, and devices for wireless communications are described. Techniques are described to enable wake-up signal (WUS) error handling at a user equipment (UE). The UE may detect an error pattern when attempting to receive a WUS from a base station based on a configuration for receiving the WUS. For example, the base station may transmit the configuration for receiving the WUS to a set of UEs including the UE. Based on detecting the error pattern, the UE may perform a mitigation operation based on determining the error pattern, such as waking up multiple cells to receive a transmission indicated by the WUS, transmitting a radio link failure indication to the base station, etc. Additionally or alternatively, the base station may transmit multiple WUSs to the UEs, such as a first WUS according to the configuration and a second WUS according to a reconfiguration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a plurality of selectable physical resource block (PRB) bundle sizes. The UE may receive downlink control information (DCI) that does not include a PRB bundling size indicator that indicates a PRB bundle size to be selected from the plurality of selectable PRB bundle sizes. The UE may select a PRB bundle size, from the plurality of selectable PRB bundle sizes, despite the DCI not including the PRB bundling size indicator. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling including an indication of a first measurement gap configuration associated with a first bandwidth part (BWP) and associated with measurements for communications at the UE over a frequency outside of the first BWP in a frequency domain. The UE may receive, from the base station, a downlink message including an indication of the first BWP. The UE may then communicate with the base station during a first time interval based on the indication of the first measurement gap configuration and the indication of the first BWP.

Abstract: A user equipment (UE) in a radio resource connection (RRC) inactive or idle state may initiate a random access procedure with a base station (BS) for initial access to a network, to resume an RRC connection, to re-establish an RRC connection, or to perform an early data transmission to a network. The BS may selectively include a timing advance (TA) medium access control (MAC) control element (CE) and an indication of a simplified timing advance command for the UE. The aspects herein may reduce the signaling overhead of the TA MAC CE. For example, the UE may enter an idle state or an inactive state. The UE may transmit a random access message to the BS with a request for timing advance simplification based, at least in part, on a TA value corresponding to the BS, wherein the TA value is applied to the transmission of the random access message.

Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to interpreting a timing advance (TA) command for members of a timing advance group (TAG), such as different uplink component carriers and/or different bandwidth parts, having different numerologies, such as different subarrier spacing (SCS). A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), a TA command. The UE interprets the TA command differently for different members of a same TAG, associated with different numerologies. The UE applies a timing adjustment when transmitting an uplink transmission to the BS based, at least in part, on the interpretation.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine one or more sidelink discontinuous reception (DRX) parameters for a configured sidelink DRX cycle. The sidelink DRX parameters may be selected by the UE or may be indicated by a base station. In some cases, the UE may transmit an indication of the sidelink DRX parameters to another UE (e.g., via a sidelink communication link). A UE may discontinuously monitor for transmissions over the sidelink communication link in accordance with the sidelink DRX parameters.

Abstract: Certain aspects of the present disclosure provide techniques for detecting power consumption conditions to trigger transmission of user equipment (UE) assistance information (UAI) for a reconfiguration request. For example, an example method by a UE generally includes detecting one or more conditions associated with at least one metric related to UE power consumption; and transmitting UAI to a network entity, in response to the detection, to request a reconfiguration of the UE to operate according to a set of one or more parameters selected based on a value of the at least one metric.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE), such as a UE with reduced capabilities, may switch from a first bandwidth part (BWP) to a second BWP to receive system information for a carrier that includes the first and second BWPs. The UE may switch to the second BWP to receive system information based on a trigger (e.g., control signaling or an expiration of a timer) and then switch back to the first BWP without additional signaling to continue operation. In some examples, the UE may receive additional signaling (e.g., data, control signaling, reference signals) in the second BWP. In some examples, a BWP switching duration may include additional time to process the system information received in the second BWP, for example if the system information includes instructions to switch to a third BWP (e.g., rather than returning to the first BWP).
