Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing beam selection. In one aspect, an initiating wireless device may determine whether a pre-grant acknowledgement associated with a first beam has been received from a responding wireless device within an expected receive time. The initiating wireless device may generate an indication to prevent the initiating wireless device from using the first beam for a blocking duration in response to determining that the pre-grant acknowledgement associated with the first beam has not been received within the expected receive time.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a serving cell operating on a first frequency, an inter-frequency communication gap configuration specifying at least one period of time during which the UE is permitted to tune from the first frequency to a second frequency to perform a positioning operation, wherein one or more neighboring cells of the serving cell are operating on the second frequency, tunes from the first frequency to the second frequency at a start of the at least one period of time, and performs, during the at least one period of time, the positioning operation on the second frequency.

Abstract: Techniques are described for wireless communication. An orthogonal frequency-division multiple access (OFDMA) configuration of an uplink channel is identified for communications in an unlicensed radio frequency spectrum band. An OFDMA waveform is generated based on the identified OFDMA configuration. The OFDMA waveform is communicated in a signal in the unlicensed radio frequency spectrum band. A virtual cell identifier of a first base station may be associated with transmissions between the first base station and a first user equipment (UE). A set of common resource blocks may be identified for transmission of a demodulation reference signal (DM-RS) between the first base station and the first UE. A configuration of an uplink channel may be dynamically selected for uplink communications in an unlicensed radio frequency spectrum band. A waveform may be generated based on the selected configuration. The waveform may be communicated in a signal in the unlicensed radio frequency spectrum band.

Abstract: In an aspect, a method of wireless communication performed by a user equipment (UE) includes determining that a positioning model error instance has occurred during a positioning occasion based on 1) a position uncertainty associated with a first position estimate satisfying positioning uncertainty error criteria, wherein the first position estimate is obtained during the positioning occasion by applying a first positioning model to radio frequency fingerprint (RFFP) measurements, 2) a positioning mismatch between the first position estimate of the UE and a second position estimate of the UE satisfying position mismatch error criteria, wherein the second position estimate of the UE is obtained during the positioning occasion by performing a positioning technique that does not use the first positioning model, or 3) any combination thereof; and determining that the first positioning model has failed based on a number of positioning model error instances satisfying positioning model failure criteria.

Abstract: Techniques described herein provide for a mobile device communicating a timing quality metric related to an uplink (UL) signal for UL and/or downlink-uplink (DL-UL) positioning techniques. The timing quality metric can be indicative of an accuracy of the transmission timing of one or more reference signals (e.g., in relation to a downlink (DL) signal or other UL reference signal) and may be communicated using an indexed and/or enumerated value. This information can be included as an information element (IE) in a report provided by the mobile device to a receiving network entity or location server.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives a set of antenna parameters for a plurality of antenna ports of a transmission-reception point (TRP), obtains positioning measurements of a plurality of positioning reference signal (PRS) resources transmitted on the plurality of antenna ports, reconstructs an underlying physical channel between the TRP and the UE based on the positioning measurements of the plurality of PRS resources, and determines a downlink angle of arrival (DL-AoD) measurement from the TRP to the UE based on the reconstructed underlying physical channel.

Abstract: Techniques for autonomous uplink (AUL) transmissions are provided that allow for efficient use of shared radio frequency spectrum band resources. A user equipment (UE) may determine a duration of an AUL transmission and modify an uplink waveform or provide an indication to a base station of one or more channel resources that may be available for base station transmissions, in order to more fully utilize shared radio frequency spectrum band resources within a maximum channel occupancy time (MCOT). A base station may activate or deactivate AUL transmissions through downlink control information (DCI) transmitted to the UE. A UE and base station may exchange various other control information to provide relatively efficient autonomous uplink transmissions and use of the shared radio frequency spectrum band resources.

Abstract: In an aspect, an LMF component may determine to trigger positioning-related action(s) at a UE. The LMF component may request that a serving BS of the UE trigger the positioning-related action(s). The serving BS may transmit a DCI communication with a CSI request field (e.g., that triggers at least CSI reporting, or triggers positioning-related action(s) only). The CSI request field may further be associated with positioning-related information including at least one PRS configuration, at least one positioning measurement request, at least one location reporting request, or a combination thereof. The UE may perform the positioning-related action(s) based on the positioning-related information.
