Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine and transmit a configuration of a periodicity and a burst size for periodically transmitting uplink data communications to a base station. The UE may periodically receive, from the base station, uplink data grants based at least in part on the periodicity and the burst size of the configuration, and periodically transmit uplink data communications based at least in part on the periodicity and the burst size of the configuration. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for remote interference mitigation between base stations using reference signals. Certain aspects provide a method for wireless communication by a first base station (BS). The method includes receiving a reference signal (RS) from a second BS. The method further includes performing interference measurement corresponding to interference from the second BS based on the RS being associated with the second BS.

Abstract: The disclosed methods and apparatuses for round trip time (RTT) based positioning include generating or receiving a measurement report. The measurement report includes, for at least one transmission-reception point (TRP), a user equipment (UE) time difference and an offset of the at least one TRP. The UE time difference is a difference of a UE transmission time of an uplink reference signals (UL RS) to the at least one TRP and an earliest reception time representing a time of arrival (TOA) at the UE of an earliest path of a downlink reference signal (DL RS) from the at least one transmission-reception point (TRP). The offset is a difference of a stronger reception time representing a TOA at the UE of a stronger path of the DL RS from the at least one TRP and the earliest reception time.

Abstract: Disclosed are techniques for positioning a user equipment (UE). In aspects, a listening node determines a first time of arrival (ToA) at the listening node of a first radio frequency (RF) signal sent by a transmission-reception point (TRP) to the UE, determines a second ToA at the listening node of a second RF signal sent by the UE to the TRP, determines a time difference between the first ToA and the second ToA, and enables a positioning entity to estimate a location of the UE based on the time difference. The positioning entity calculates a distance between the listening node and the UE based on the time difference, a propagation time between the TRP and the listening node, a propagation time between the TRP and the UE, and a time difference between a ToA of the first RF signal at the UE and a transmission time of the second RF signal.

Abstract: Disclosed are techniques for group reporting of UE receive-transmit (Rx-Tx) time difference measurements for multi-RTT positioning. A plurality of downlink reference signals (DL RSs) are received from a plurality of transmission reception points (TRPs). A corresponding plurality of uplink reference signals (UL RSs) are transmitted to the plurality of TRPs. One or more numerology factors are determined for the plurality of TRPs. A measurement report is generated for the plurality of TRPs based on the numerology factors. The measurement report is transmitted to a network entity. The measurement report includes UE receive-transmit (Rx-Tx) time difference measurements for at least two of the TRPs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a sounding reference signal (SRS) resource set to be used to signal a virtual port used for a physical uplink shared channel (PUSCH) communication, wherein the virtual port is a combination of at least two non-coherent or partially-coherent antenna ports of the UE using precoding and cyclic delay diversity; and transmit an SRS for the at least two non-coherent or partially-coherent antenna ports using one or more resources of the SRS resource set. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter may identify a set of resource elements on which to transmit a reference signal based at least in part on a numerology being used by the transmitter and at least one of a maximum system numerology or a minimum system numerology; and transmit the reference signal on the identified set of resource elements. In some aspects, a receiver may identify a set of resource elements from which to obtain a reference signal based at least in part on a numerology being used by the receiver and at least one of a maximum system numerology or a minimum system numerology; and obtain the reference signal from the identified set of resource elements. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide techniques for a user equipment (UE) to set uplink power control for a long uplink burst and a short uplink burst. The UE receives uplink power control information including a first set of power control parameters for a long uplink burst and a second set of power control parameters for a short uplink burst with the sets of power control parameters being different from each other. The UE configures uplink power control for the long uplink burst based at least on the first set of power control parameters and the short uplink burst based at least on the second set of power control parameters. The UE sends at least one of a long uplink burst and a short uplink burst based on the corresponding uplink power control and sends at least one uplink power-headroom report for the long uplink burst and short uplink burst.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In certain configurations, the apparatus may include an eMBB UE. The apparatus may monitor a single preconfigured mini-slot in each of a plurality of slots for a PI. The apparatus may receive the PI in the single preconfigured mini-slot of a first slot of the plurality of slots. In certain aspects, the PI may include a resource index associated with a reduced transmission power by the UE. In certain other aspects, the resource index may include one or more resources in a second slot. The apparatus may transmit at least one packet with the reduced transmission power on the one or more resources in the second slot or refraining from transmitting the at least one packet on the one or more resources in the second slot.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE may receive configuration information that signals a first set of resources and a second set of resources. The configuration information may indicate that the first set of resources is associated with high priority transmissions and the second set of resources is associated with low priority transmissions. The UE may select, based at least in part on the configuration information and a priority of a transmission, either the first set of resources or the second set of resources for transmitting the transmission. The selecting of the first set of resources or the second set of resources may be based on latency requirements or reliability requirements of transmissions to be transmitted by the UE. The UE may transmit the transmission using the selected set of resources. Other aspects are provided.
