Abstract: Aspects are provided which allow a base station to dynamically select or indicate an active CORESET associated with a search space or set of PDCCH candidates. The base station selects, for at least one UE, an active CORESET associated with a search space for a period of time. The base station transmits a dynamic indication of the active CORESET associated with the search space to the at least one UE. A UE receives the dynamic indication of the active CORESET associated with the search space for the period of time. The UE then monitors for a downlink control channel during the period of time based on the dynamic indication of the active CORESET.

Abstract: Disclosed are techniques related to wireless communication. In an aspect, a sequence generating entity factorizes a comb size N into prime factors of N, and generates one or more offset sequences for a reference signal for positioning based on one or more sequence lists associated with the prime factors of N and a number of symbols M over which the reference signal is scheduled.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive, from a base station, a configuration indicating a channel quality threshold that the UE may use to identify an interference-based beam failure indicator type. The UE may receive a reference signal for performing one or more signal measurements in accordance with the configuration. Based on the one or more signal measurements and the channel quality threshold, the UE may report an indication of the type of beam failure indicator to the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node may transmit, to a second node on a beamformed link from the first node to the second node, a first signal, wherein the first node and the second node are associated with common timing; determine whether a second signal, based at least in part on the first signal, is received on a beamformed link from the second node to the first node; and transmit a third signal based at least in part on receiving the second signal or perform a sidelink beam failure recovery procedure based at least in part on determining that the second signal is not received. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may transmit, to a second wireless device, capability control signaling indicating a first quantity of beam switches is supported within a first time period for a first antenna subarray, a first antenna module, or both, of the first wireless device. The first wireless device may receive, from the second wireless device in accordance with the capability control signaling, a grant scheduling one or more messages and indicating a set of beams of the first wireless device over which to communicate the one or more messages in respective transmission time intervals (TTIs) of the first time period. The first wireless device may then transmit or receive, over the first time period using the first antenna subarray, the first antenna module, or both, the one or more messages using the set of beams.

Abstract: Disclosed are techniques for no-delay scheduled location requests. In an aspect, a user equipment (UE) receives, from a network node, a no-delay scheduled location request that identifies a future time T1 for reporting a location of the UE, e.g., a scheduled location request having a response quality of service (QoS) attribute indicating no delay. In some aspects, the UE determines, at time T2

Abstract: Methods, systems, and devices for wireless communications are described. A device in a wireless network may identify a resource for wireless communication, the resource being in a first state where the resource is active for wireless communication and is inactive for a communication failure recovery procedure. The device may determine that a communication failure has occurred during a first communication period. The device may transition, during a second communication period and based at least in part on the communication failure, the resource to a second state where the resource is inactive for wireless communication and is active for the communication failure recovery procedure. The device may perform the communication failure recovery procedure using the resource transitioned to the second state.

Abstract: Methods, systems, and devices for transmit power control for positioning using non-serving cells are described. A user equipment (UE) may determine that an uplink reference signal may be associated with a positioning procedure. In some cases, the positioning procedure may include transmission, by the UE, of the reference signal to a non-serving cell, which may be farther away from the UE than a serving cell. The UE may determine an absence of a parameter associated with a transmit power for transmitting the reference signal. Based on the absence, the UE may determine the transmit power based on parameters received from a serving cell, based on configuration information, based on a message intercepted from the non-serving cell, or based on other considerations or information. In some cases, the UE may determine the transmit power such that the likelihood of the non-serving cell receiving the reference signal is increased.

Abstract: Disclosed are methods and apparatuses for providing configurable reference signal timing difference (RSTD) search windows for positioning. In an aspect, an RSTD search window is configured based on a positioning reference signal (PRS) configuration. The RSTD search window is provided to the UE. A plurality of PRS is transmitted from a network entity to a user equipment (UE), each PRS having the PRS configuration. The plurality of PRS are transmitted in a subset that is less than all subcarriers over a given bandwidth.
