Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, in a control channel, a first grant identifying a first set of resources of a first data channel on which the UE is to monitor for one or more second grants, the first data channel being downlink. The UE may monitor the first set of resources in the first data channel for the one or more second grants, the one or more second grants identifying a second set of resources of a second data channel on which the UE is to perform data communications. The UE may transmit, based at least in part on the monitoring the first set of resources, a feedback message associated with receipt of the one or more second grants.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support enhanced positioning operations using a repeater. In a first aspect, a method of wireless communication includes receiving, by the UE, an instruction from a base station (BS) to perform a first signal measurement at a first time and a second signal measurement at a second time; determining, by the UE and based on the instruction, a first signal characteristic of a first signal during the first time corresponding to a time when a first repeater is repeating the first signal from a base station; determining, by the UE and based on the instruction, a second signal characteristic of a second signal during the second time corresponding to a time when the first repeater is not repeating the second signal; and a location of the UE is determined based on the first signal characteristic and the second signal characteristic.

A method for wireless communication at a user equipment (UE) includes identifying a physical uplink shared channel (PUSCH) to transmit in an uplink pilot time slot (UpPTS) of a subframe, determining whether to transmit uplink control information (UCI) on the PUSCH in the UpPTS, and transmitting the PUSCH in the UpPTS based at least in part on the determining. A method for wireless communication at a network access device includes determining whether to schedule a transmission of UCI on a PUSCH in a UpPTS of a subframe, scheduling the PUSCH in the UpPTS based at least in part on the determining, and transmitting, to a UE, scheduling information for the PUSCH in the UpPTS.

Abstract: Techniques are described for wireless communications. One method includes determining a contention window size for a first broadcast transmission or a first multicast transmission on at least one channel of a shared radio frequency spectrum band, where the first broadcast transmission or the first multicast transmission is targeted for a first plurality of UEs, and contending for access to the at least one channel of the shared radio frequency spectrum band for the first broadcast transmission or the first multicast transmission based at least in part on the determined contention window size. In some cases, the first broadcast transmission or the first multicast transmission may be an example of a multipoint transmission, which may include a coordinated multipoint transmission.

Abstract: In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications for generating, by a network entity for a user equipment (UE), a synchronization signal block (SSB) and an additional resource signal (RS) based on a variable function of a SSB subcarrier spacing (SCS) for communication after initial acquisition; and transmitting, by the network entity to the UE, the SSB including the additional RS.

Abstract: Methods related to wireless communications systems and transmissions in an unlicensed radio frequency band of a shared spectrum are provided. A device determines whether one or more criteria are satisfied for accessing an unlicensed band of a shared spectrum without performing a listen-before-talk (LBT). The device transmits a communication signal in the unlicensed band without performing LBT in response to determining that the one or more criteria are satisfied.

Abstract: Disclosed are techniques for positioning. In an aspect, a positioning entity determines a first time of flight (ToF) of a first non-line-of-sight (NLOS) multipath component of a first radio frequency (RF) signal transmitted by a physical transmission-reception point (TRP) to at least a first user equipment (UE), determines a location of a virtual TRP associated with the physical TRP based at least on the first ToF, and determines a location of at least a second UE based, at least in part, on the location of the virtual TRP.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform a transmission detection procedure on each base station before combining control information. The UE may use demodulation reference signals (DMRS) as a detection mechanism. If the UE detects a DMRS from a base station, the UE may determine that a control resource set associated with the base station is valid for combining. If the UE does not detect DMRS from the base station, the UE may refrain from combining control information from the base station. In another example, base stations that pass a listen-before-talk (LBT) pr6ocedure may transmit a preamble before transmitting control information. A preamble may carry a preamble sequence associated with a specific control resource set. The UE may identify a preamble sequence and determine that the corresponding control resource set is valid for control information combining.

Abstract: In order to conserve power resources for low complexity UEs, a base station may apparatus dynamically adjust a bandwidth configuration of a UE or the base station and communicates with the UE according to the dynamically adjusted bandwidth configuration. The communication may be narrowband communication. A UE may apparatus dynamically adjust a bandwidth configuration of the UE and communicates with a base station based on the dynamically adjusted bandwidth configuration. The dynamically adjusted bandwidth configuration may correspond to a function performed by the UE.

Abstract: Methods, systems, and devices for wireless communications are described techniques provide for the identification of a sequence of beamforming parameters that are used for communications between a user equipment (UE) and a base station using a sequence of transmission beams. A UE may measure received reference signals that are transmitted in a series of downlink transmission beams from a base station, and report measurement parameters associated with the downlink transmission beams to the base station as part of a beam tracking and beam refinement procedure. The base station may provide transmission configuration indicator (TCI) states that are associated with each transmission beam. The TCI states may be recorded over a course of a periodic movement of the UE, and may be used deterministically to identify beamforming parameters for transmission and reception of a subsequent series of downlink transmission beams when the UE makes a subsequent same periodic movement.
