Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive, from a base station, signaling that schedules a first uplink shared channel message and a second uplink shared channel message (e.g., physical uplink shared channel (PUSCH) messages) from the UE to the base station within a first component carrier. The first and second uplink shared channel messages may at least partially overlap, where at least one of the first or second uplink shared channel messages includes a configured grant uplink shared channel message (CG-PUSCH). The UE may transmit the first and second uplink shared channel messages to the base station in accordance with a transmission configuration for transmitting temporally overlapping uplink shared channel messages.

Abstract: Techniques are provided for passive positioning of user equipment (UE). An example method for passive positioning of a user equipment includes receiving a first positioning reference signal from a first station at a first time, receiving a second positioning reference signal from a second station at a second time, receiving a turnaround time value associated with the first positioning reference signal and the second positioning reference signal, and a distance value based on a location of the first station and a location of the second station, and determining a time difference of arrival based at least in part on the turnaround time value, the distance value, the first time, and the second time.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an adjusted contention window size for a listen-before-talk (LBT) procedure that increases channel access time fairness between a plurality of different groups of UEs. The UE may determine, via the LBT procedure, that a channel is idle based at least in part on the adjusted contention window size. The UE may transmit, to other UEs in a group of UEs that includes the UE, control information that enables a group channel occupancy time (COT) associated with the channel to be shared with the other UEs in the group of UEs. Numerous other aspects are described.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support managing allocation of configured grant (CG) resources for uplink transmissions using a polynomial over Galois field in a wireless communication system. In particular, a user equipment (UE) may be configured (e.g., by a base station) to determine a resource to access, from a resource pool configured for each CG occasion of a CG configuration, based on a polynomial over Galois field configured for the UE. The polynomial over Galois field may include a parameter p, and the UE may be configured with a mapping that maps the absolute time (e.g., a slot index or a symbol index) of a GC occasion to an index between 0 and p−1 that is used as input to the polynomial The result of the polynomial is used to determine the resource to access by the UE at the CG occasion.

Abstract: Methods, systems, and devices for wireless communications are described. A first device may cooperate with a second device to form a virtual device configured to communicate with a radio access network. The virtual device may appear as a single device from the perspective of the radio access network. Subsequently, a third device may be identified for replacing the second device within the virtual device. Based on the third device being identified, procedures for handing over communications from the second device to the third device may be executed. The procedures may include a beam management procedure, a random-access procedure, a mobility management procedure, or any combination thereof.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that handling of a protocol data unit (PDU) by the UE is preempted. The UE may transmit an indication that the preempted PDU is preempted. The indication may be generated by a physical layer of the UE, or by a MAC layer of the UE. The UE may receive information for a transmission of the preempted PDU. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling configuring the UE with a plurality of component carriers (CCs) for communicating with a base station and a semi-persistent resource allocation of a resource for each CC of the plurality of CCs. The UE may identify an availability indicator that indicates availability of the resource of the semi-persistent resource allocation on each CC of the plurality of CCs. The UE may communicate a data transmission via at least a subset of the plurality of CCs based at least in part on the availability indicator.

Abstract: A wireless network including user equipment (UE) and base stations is configured to perform position determination with low latency and synchronized to a common time within a wireless network. The UE and base stations are configured to perform positioning measurements at a specific time point or within a window around the time point in a measurement period. The time point may be relative to a timing event within the wireless network, such as the beginning or end of a positioning reference signal window or a specific message in a layer 1 or layer 2 transmission. A location server may be provided with the positioning measurements or a position estimate from the UE and provide the position estimate to an external client within the measurement period.

Abstract: Methods, systems, and devices for wireless communications are described. One method may include an eNB predetermining a plurality of bandwidth parts to monitor based on resource reservation information received from at least one base station, and transmitting information indicative of the predetermined bandwidth parts in a radio resource control (RRC) message. In some cases, a base station may transmit information indicative of predetermined bandwidth parts including a monitoring schedule to monitor either the first bandwidth part or the second bandwidth part in a timeslot of a set of timeslots. Another method may include receiving a predetermined monitoring schedule from a base station, and selecting a plurality of bandwidth parts to monitor on a physical downlink control channel based on the received schedule.

Abstract: Methods, systems, and devices for wireless communications are described for management of conditional handover (CHO) configurations. A source base station may configure a user equipment (UE) with one or more CHO configurations for multiple target base stations. The CHO configurations may provide, for each target base station, one or more associated conditions that may trigger the UE to initiate a handover to the particular target base station, or to deconfigure a CHO configuration, such as based on a measurement threshold of one or more target base station measurements, one or more source base station measurements, or combinations thereof. The CHO configurations may also include failure handling information for initiating one or more subsequent handovers responsive to a failure of an initial handover attempt.
