Abstract: This disclosure provides systems, methods and apparatus for wireless communication. In one aspect, a user equipment (UE) may generate an indication of a first doppler shift associated with the wireless communication device moving with reference to a first target base station (BS), obtain, from the serving BS, a handover command for conditional handover (CHO) (with the handover command including a first trigger for handover to the first target BS), and synchronize with the first target BS during CHO after the first trigger is met, wherein the first trigger is associated with the first doppler shift. In another aspect, a serving BS generates the handover command for CHO and provides the handover command to the UE. The UE is to synchronize with the first target BS during CHO after the first trigger associated with a first doppler shift is met.

Abstract: Methods, systems, and devices for wireless communications are described. A base station to communicate with a set of user equipments (UEs) in a spatial division multiplexing (SDM) configuration for dynamic spectrum sharing (DSS) communications. One or more first UEs of the set of UEs may communicate via a first radio access technology (RAT), and one or more second UEs may communicate via a second RAT in a multiple-user multiple-input multiple output (MU-MIMO) configuration. The base station may indicate the SDM configuration to one or more of the set of UEs. In some examples, the base station may transmit an indication to the set of UEs which may indicate a set of resources to be used for DSS communications. In some examples, the SDM configuration may specify one or more reference signal patterns for communicating in the set of resources.

Abstract: In certain aspects, a method for wireless communication at a user equipment (UE) includes attempting to receive, from a first base station, data via a first communication link, generating a radio link control (RLC) status report indicating a status of the data at the UE, and transmitting, to a second base station, the RLC status report via a second communication link. The UE may be simultaneously connected to the first base station and the second base station using dual connectivity. In one example, the first base station may be configured as a secondary cell group (SCG) and the second base station may be configured as a master cell group (MCG). In one example, the first communication link may be a New Radio (NR) link and the second communication link may be a Long-Term Evolution (LTE) link.

Abstract: Methods, systems, and devices for wireless communication are described to support reducing conflicts with between scheduling request opportunities and downlink resources. A base station may configure a user equipment (UE) with a scheduling request periodicity and offset for identifying scheduling request opportunities. The UE and base station may apply the periodicity and the offset to a first subset of time periods of a set of multiple time periods, where the first subset of time periods may include scheduling request opportunities that do not overlap with resources allocated for downlink transmissions. Based on applying the offset and periodicity to the first subset of time periods, the UE may identify a scheduling request opportunity, in a first time period of the first subset, and may transmit a scheduling request to the base station via the scheduling request opportunity.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an uplink grant via downlink control signaling for a cell group. The UE may determine an uplink error rate for the cell group based on the downlink control signaling. The UE may identify a radio link failure condition for uplink based on the uplink error rate exceeding an uplink error rate threshold. The UE may transmit a radio link failure indication indicating that the radio link failure condition is based on the uplink error rate. The network may send a cell group reconfiguration message to the UE to release the cell group.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit, to a user equipment (UE), a bandwidth size indication that indicates a respective bandwidth size configured for each operating configuration of a set of operating configurations supported at the UE. The UE may transmit, to the base station, a priority indication for at least one operating configuration of the set of operating configurations based on the bandwidth size indication. The priority indication may correspond to a bandwidth size of the at least one operating criterion satisfying one or more criteria for data traffic. The base station may transmit, to the UE, a configuration indication that indicates to communicate according to a first operating configuration of the set of operating configurations based on the priority indication. The UE may communicate the data traffic with the base station based on the first operating configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A repeater may transmit a beacon signal that indicates a presence of the repeater, where the repeater is configured to repeat signals to one or more user equipments (UEs) within a wireless communications system. The repeater may receive a signal from at least one base station within a time-frequency resource that is shared by a plurality of neighboring base stations in response to transmitting the beacon signal. The repeater may transmit an amplified version of the received signal to the one or more UEs.

Abstract: A method for wireless communication performed by a user equipment (UE) includes transmitting, to a first network, a first message comprising a first measurement gap configuration, a measurement gap reconfiguration, a selection from a measurement gap pool, or a measurement gap release. The method also includes receiving a second message, from the first network. The second message may configure a measurement gap, reconfigure a measurement gap, or release a measurement gap. The second message may also suspend data communication from the UE during a configured measurement gap. The method additionally includes suspending communication with the first network during the configured measurement gap. The communication may be suspended to save power, tune away for a multiple subscriber identity module (MSIM) of the UE, or measure a neighbor cell.
