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: Generating, by a user equipment (UE) of a wireless access network, for a set of contention-based random access occasions of a base station of the network, a random number over an interval. For the generated random number meeting a threshold value within the interval, transmitting, by the UE and to the base station, a random access preamble within one of the random access occasions of the set. For the generated random number not meeting the threshold value, attempting, by the UE, contention-based access to the network within a subsequent set of random access occasions of the base station, the subsequent set of random access occasions occurring after the set of contention-based random access occasions of the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a relay device may receive, from a first user equipment (UE) on a sidelink channel, a buffer status report. Accordingly, the relay device may receive, from a base station, a grant of an uplink resource based at least in part on determining a priority of data associated with the buffer status report. Additionally, the relay device may transmit, to the base station, the buffer status report based at least in part on receiving the grant of the uplink resource. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for coordinated sidelink power savings configurations. A wireless node may select a sidelink power savings configuration to use for a sidelink between the wireless node and a user equipment (UE), provide the selected configuration to the UE, and follow the configuration for the sidelink. The selection may be based on input from the UE or without input from the UE. The selection may be a current power savings configuration at the wireless node, a power savings configuration suggest by the UE, or a different power savings configuration determined by the wireless node based on the current and suggested power savings configuration. When a new UE connects to the wireless node, the wireless node may reselect a power savings configuration to use for the sidelinks and provide the reselected power savings configuration to the UEs having a sidelink with the wireless node.

Abstract: The present disclosure relates to methods and devices for wireless communication of an apparatus, e.g., a UE and/or a base station. In one aspect, the apparatus may receive, from a base station, at least one SSB. The apparatus may also determine a RSRP of the at least one SSB. Additionally, the apparatus may transmit, to the base station if the RSRP of all of the at least one SSB is less than a threshold, an indication of a reduced UE capability of the UE during a RACH procedure. The apparatus may also transmit, to the base station if the RSRP of one of the at least one SSB is greater than or equal to the threshold, the indication of the reduced UE capability of the UE after entering into a RRC connected state upon completion of the RACH procedure.

Abstract: Methods, systems, and devices for wireless communications are described in which a narrowband device may communicate in a wireless communications network according to frequency hopping techniques. Devices using narrowband communications and frequency hopping techniques may maintain separate radio link monitoring (RLM) processes, beam failure detection (BFD) processes, beam failure recovery (BFR) processes, or combinations thereof, for multiple bandwidth parts (BWPs) or hop regions of a full channel bandwidth. Such separate processes may provide for enhanced estimates of beam failures per BWP or hop region, which may be used to enhance communications reliability.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling from a base station that indicates a multicast or broadcast wake up signal (WUS) format. The UE may receive a multicast or broadcast WUS from the base station during a WUS monitoring occasion of a connected mode discontinuous reception (C-DRX) cycle in accordance with the control signaling. The multicast or broadcast WUS may indicate upcoming transmissions for a set of multicast or broadcast services (MBSs). If, for example, the UE is subscribed to a first MBS from the set of MBSs and the multicast or broadcast WUS indicates an upcoming transmission for the first MBS, the UE may monitor for the upcoming transmission during an active duration of the C-DRX cycle. Otherwise, the UE may enter a sleep mode to conserve power.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a device, such as a user equipment (UE), may report power headroom measurements. To support accurate and reliable power headroom reports (PHRs), the UE may receive a first downlink control information (DCI) transmission for a first cell and determine whether a second DCI transmission for a second cell is received. The UE may generate the PHR based on whether a second DCI transmission was received after the first DCI transmission and may transmit the PHR including power headroom values for both cells. The UE may determine whether to perform an actual or virtual power headroom calculation for the second cell based on when the second DCI was received. Additionally or alternatively, the UE may determine whether to drop resources scheduled by the first or second DCI and may transmit the PHR in the remaining resources.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, such as a user equipment (UE) may receive control signaling indicating a set of configurations including a set of random access channel (RACH) configurations or a set of scheduling request (SR) configurations. At least one RACH configuration of the set of RACH configurations includes a UE-group common RACH configuration or at least one SR configuration of the set of SR configurations includes a UE-group common SR configuration. The UE may select one or more configurations of the set of RACH configurations or the set of SR configurations based on receiving the control signaling and may perform the wireless communications.
