Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that one or more threshold criteria are satisfied, wherein the one or more threshold criteria include at least one of a first value for an uplink grant rate, a second value for a buffer size, or a third value for a packet data convergence protocol discard rate, wherein the one or more threshold criteria relate to a network condition with less than a reference uplink throughput and greater than a reference downlink throughput. The UE may transmit information identifying one or more adjusted measurement values based at least in part on the determination of the one or more threshold criteria. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first signal in a first slot, wherein the first slot corresponds to a physical downlink control channel monitoring occasion in a second slot with a defined characteristic. The UE may receive a second signal in a third slot, wherein the third slot is based at least in part on the second slot, the defined characteristic, and a shift value. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, an absolute threshold synchronization signal block (SSB) consolidation parameter. The TUE may determine whether a threshold value indicated in the absolute threshold SSB consolidation parameter satisfies a predefined value threshold. The UE may set a specific network deployment flag based at least in part on whether the threshold value satisfies the predefined value threshold. The UE may determine a cell measurement result based at least in part on the specific network deployment flag. The UE may perform a downlink beam selection and a beam switch evaluation based at least in part on the specific network deployment flag. Numerous other aspects are described.

Abstract: A first network node (e.g., a UE) may receive, from a second BS network node (e.g., a base station), DCI. The first network node may perform, based on the DCI, a BWP switch from a first BWP to a second BWP. The first network node may perform, after the BWP switch, a BWP switch failure detection procedure that results in a first determination or a second determination. The first determination may be indicative that the BWP switch was successful and the second determination may be indicative that the BWP switch was not successful. To perform the BWP switch failure detection procedure, the first network node may determine whether one or more failure conditions are satisfied. The one or more failure conditions may include at least one of a BLER greater than a threshold, occurrence of one or more tune away events, or non-receipt of an uplink grant on the second BWP.

Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. The UE may identify that the UE is operating in a high mobility environment, that a first reference signal received power associated with a first cell is decreasing, and that a second reference signal received power associated with a second cell is increasing. The UE may transmit a request for a handover from the first cell to the second cell based on the identifying, the transmitting performed at a time that may be based on one or more network-configured handover timing parameters having one or more values adjusted by the UE. The UE may receive a handover command in response to transmitting the request for handover. The UE may perform a handover from the first cell to the second cell in response to the handover command.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may communicate with a first network device in a first communications system (e.g., a non-standalone (NSA) system) prior to initiating a handover to a second communications system (e.g., a standalone (SA) system). In some examples, the UE may receive a first tracking reference signal (TRS) from the first network device using a first transmission configuration indicator (TCI) state. The first network device may include an indication of the first TCI state in a control message. The UE may initiate a handover from the first network device to the second network device. Subsequent to the handover, the UE may receive a second TRS from the second network device. The UE may receive the second TRS using the first TCI state based on determining that one or more antenna port configuration conditions are satisfied.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) using information identified via radio access technology (RAT) (e.g., Long Term Evolution (LTE)) to support communications in another RAT (e.g., New Radio (NR)). For example, the UE may receive, from a first base station operating according to a first radio access technology an indication of a high speed associated with a first wireless connection of the UE with the first base station. The UE may perform a channel estimation procedure for the first wireless connection to generate a Doppler value based on receiving the indication. The UE may apply the generated Doppler value to a frequency tracking loop or a time tracking loop for communications with a second base station via a second wireless connection, wherein the second base station is operating according to a second RAT.
