Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify, while camped on a first cell associated with a first radio access technology (RAT), a power management level for a communication using a second RAT, wherein the power management level indicates an available power for the communication using the second RAT, and wherein the available power is based at least in part on an exposure rate or an absorption rate. The UE may delay a transmission of a measurement report on the first cell based at least in part on the identification of the power management level. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and another device (e.g., another UE) may transmit messages on a shared channel accessed in a half-duplex manner (e.g., within a vehicle-to-everything (V2X) network). The UE and the other device may transmit messages on semi-persistently scheduled (SPS) resources. A message of the UE and a transmission of the other device may collide (e.g., be transmitted in the same subframe). The UE may employ muting and measuring, in which the UE may refrain from transmitting on a SPS resource and may detect the transmission of the other device. Upon detection of other transmissions, the UE may perform resource reselection. During resource selection or resource reselection, the UE may exclude an entire subframe of candidate resources if one of the candidate resources of the subframe is mapped to a resource associated with a transmission from another device.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station according to a first radio access technology (RAT) in a first frequency range. The UE may perform measurements on a set of candidate cells of a second RAT or a second frequency range based on a determination for the UE to operate according to the second RAT or the second frequency range. The UE may perform a mobility procedure to establish a connection with a first cell of the set of candidate cells based on a determination that a first value of a first measurement parameter for the first cell satisfies a first threshold, and further based on a comparison of a different, second value of a second measurement parameter for the first cell to a second threshold.

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: 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 device may selectively listen for a tracking reference signal (TRS) during connected mode discontinuous reception (CDRx) based on whether the device is to switch between repeaters of a base station (such as during travel). A device may determine whether the device is in a high speed train (HST) scenario (such as based on a difference in frequency errors generated using a synchronization signal block (SSB) and generated using a TRS, based on a trajectory of a frequency error or a frequency error difference over time, based on instantaneous frequency errors, etc.). When the device is in a HST scenario, the device listens for a TRS during CDRx, and the device generates a frequency error using the TRS. When the device is not in a HST scenario, the device prevents listening for a TRS during CDRx (with a SSB received during CDRx to be used to generate a frequency error).

Abstract: A method of wireless communication by a device includes detecting whether the device is in an outdoor environment in response to a start of a reevaluation timer. The method also determines a mobility level of the device in response to the start of the reevaluation timer. The method further includes enabling a vehicle-to-everything (V2X) pedestrian mode in response to the device being in the outdoor environment and/or the mobility level exceeding a threshold value.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes communicating control signaling scheduling a sidelink transmission via a physical sidelink channel, receiving, by a first user equipment (UE), the sidelink transmission including one or more reference signals from a second UE via the physical sidelink channel based on the control signaling, and monitoring the physical sidelink channel based on time synchronization, frequency synchronization, or both, determined using the one or more reference signals.

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.
