Some aspects provide a method for wireless communication by a first wireless device. The method generally includes transmitting control information regarding at least one of scheduling or configuration of a channel state information (CSI) report to be transmitted by the first wireless device. The method generally includes generating the CSI report based on one or more CSI reference signals (CSI-RSs) received by the first wireless device. The method generally includes and transmitting the CSI report in accordance with the control information.

CSI report setting by the CSI-transmitting user equipment

This disclosure provides systems, methods, and devices for wireless communication that support positioning reference signal (PRS)-assisted beam management. In particular, various aspects of the present disclosure provide techniques for a network entity to select a beam of a plurality of beams for communications between a base station and a user equipment (UE) based on line-of-sight (LOS) path detection results. In some implementations, the LOS path detection results may include an indication as to whether a PRS includes an LOS path signal and/or an NLOS, and/or a signal strength of the LOS path signal, as well as other information that a network entity (e.g., a UE or a base station) may use in a beam management procedure (e.g., to select a beam). Other aspects and features are also claimed and described.

Positioning reference signals (PRS)-assisted beam management for communication

In an aspect, a location server may receive a request to determine a position of a first mobile device at a first scheduled time. The location server may determine a first position of a second mobile device during a first time window before the first scheduled time. The location server may configure the second mobile device to perform positioning operations during a second time window corresponding to the first scheduled time to assist in the determination of the position of the first mobile device at the first scheduled time.

Scheduled positioning of target devices using mobile anchor devices

Methods, systems, and devices for wireless communications are described. In one aspect, a first user equipment (UE) may transmit an indication of non-preferred resources to a second UE and an indication of an amount of transmit power reduction for the second UE to observe for a sidelink transmission on the non-preferred resources. In another aspect, a first UE may transmit an indication of an amount of transmit power reduction for a second UE to observe for a sidelink transmission on conflicting resources (e.g., resources reserved by the second UE and a third UE). Because the second UE may transmit on the non-preferred resources or the conflicting resources with reduced power (e.g., rather than suppressing transmissions on the non-preferred resources or the conflicting resources), the utilization of the non-preferred resources or the conflicting resources may be improved.

Transmit power adjustment based on inter-user equipment coordination

Methods, systems, and devices for wireless communications are described. A base station may identify time and frequency resources for a physical downlink shared channel (PDSCH) to be transmitted to a user equipment (UE) in a first transmission time interval (TTI). The base station may transmit configuration information for a control channel search space set in a second TTI. The second TTI may precede the first TTI. The configuration information may include an indication of an absence of a physical downlink control channel (PDCCH) transmission to send in the control channel search space set indicating the identified time and frequency resources for the PDSCH, and a set of time and frequency resources for the control channel search space set. The UE may receive the configuration information and identify the time and frequency resources allocated for the PDSCH in the second TTI, and receive the PDSCH transmission in the second TTI.

Virtual search spaces for beam indication

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may determine, based at least in part on a channel sensing using a receive beam of the first UE, preferred resources or non-preferred resources of the first UE for a sidelink transmission by a second UE. The UE may transmit, to the second UE, inter-UE coordination (IUC) information that indicates: a transmit beam of the second UE, and the preferred resources or the non-preferred resources of the first UE, wherein the preferred resources or the non-preferred resources of the first UE are to be applied to the transmit beam of the second UE indicated in the IUC information. Numerous other aspects are described.

Transmitting inter-user-equipment coordination information based at least in part on beamforming

In some implementations, a method of wireless communication includes selecting, at a user equipment (UE), one or more control resource sets (CORESETs) from a plurality of CORESETs corresponding to the UE. At least one of the plurality of CORESETs corresponds to multiple active transmission configuration indicator (TCI) states. The method further includes performing a radio link monitoring (RLM) operation, a beam failure detection (BFD) operation, or both, based on one or more reference signals (RSs) corresponding to active TCI states associated with the one or more selected CORESETs.

Radio link monitoring (RLM)/beam failure detection (BFD) reference signal (RS) for coresets with multiple active transmission configuration indicator (TCI) states

Methods, systems, and devices for wireless communications are described. Wireless devices may be configured to support techniques for bi-directional discontinuous reception (DRX) alignment and centralized DRX alignment. In the context of bi-directional DRX alignment, DRX configurations at two respective user equipments (UEs) are first established in a first direction, and then DRX configurations are then established in the reverse direction based on the previously-established DRX configurations. In particular, DRX configurations in the reverse direction may be selected such that the Uu and sidelink DRX configurations are aligned at the respective UEs and across the UEs. Comparatively, in the context of centralized DRX alignment, a master base station receives 'candidate' Uu and sidelink DRX configurations for multiple UEs, and selects Uu and sidelink DRX configurations for each UE from the sets of candidate DRX configurations in order to ensure DRX alignment across the respective UEs.

Discontinuous reception alignment for wireless communications

Positioning of a UE is supported in a Radio Resource Control (RRC) Inactive state. The UE receives a request for periodic or triggered location and enters the RRC Inactive state. When an event is detected, the UE sends an RRC Resume Request to a gNB that includes an indication of the event. The indication may be an event report that may include downlink positioning measurements. The gNB forwards the event report to a location server, and may later receive and return an event report acknowledgement to the UE in an RRC Release. The indication may instead trigger uplink positioning, with the base station sending an uplink Sounding Reference Signal (SRS) configuration to the UE in an RRC Release, causing the UE to transmit uplink SRS signals to be measured by gNBs. For uplink related position methods like RTT, the gNB can receive both types of indication.

Method and apparatus for location of a user equipment in an inactive state

Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) identifies a set of positioning sources, each positioning source comprising a positioning reference signal (PRS) resource, a PRS resource set, a PRS frequency layer, and/or a transmission/reception point (TRP). From the set of positioning sources, the UE identifies a consistency group comprising a collection of positioning sources grouped based on expected values of at least one metric of a reference signal from each positioning source, measured values of the at least one metric for the reference signal from each positioning source, and an error threshold. The UE identifies one or more subsets of positioning sources within the consistency group, each subset having at least one metric error value. The UE reports, to a network entity, information about the consistency group and information about at least one of the subsets of positioning sources within the consistency group.

Prioritization of positioning-related reports in uplink

A first UE may establish a sidelink connection with at least one second UE via a first PCC. The first PCC and a first set of SCCs may be associated with a first transmission of the first UE. The sidelink connection with the at least one second UE may be associated with carrier aggregation. The first UE may detect, and transmit a first indication, that at least one of (i) the sidelink connection is associated with an RLF value that is within an RLF threshold of an RLF limit, or (ii) the first set of SCCs is capable of maintaining the sidelink connection. The first UE may receive, based on the first indication, a second indication of a switch of the sidelink connection from the first PCC to a first SCC of the first set of SCCs.

Radio link management for sidelink carrier aggregation component carriers

Disclosed are techniques for wireless communication. In an aspect, a relative location anchor group (RLAG) may facilitate a position estimation procedure in an environment where absolute position estimation accuracy is below a threshold. An absolute position estimate derived via the RLAG may optionally be transformed to a true (or more accurate) position estimate via transformation information. In some cases, new anchors may be added to the RLAG after performing a position estimation procedure with the RLAG. In other designs, a local coordinate system (LCS) may be used for position estimation in lieu of a global coordinate system (GCS), such as WGS 84.

Relative location anchor group and local coordinate system

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an activated UE relay measurement configuration that includes one or more first sidelink measurement parameters. The UE may receive a deactivated UE relay measurement configuration that includes one or more second sidelink measurement parameters, wherein values for the one or more first sidelink measurement parameters and values for the one or more second sidelink measurement parameters are different. The UE may perform one or more sidelink measurements based at least in part on at least one of the activated UE relate measurement configuration or the deactivated UE relay measurement configuration. Numerous other aspects are described.

Sidelink measurement configuration and reporting for a user equipment relay

A base station may instruct a UE to use at least one weighting factor associated with a CR for the UE, and the UE may apply the at least one weighting factor to the one or more resources scheduled for the PSSCH transmission to determine the CR. The UE may transmit the PSSCH in the one or more resources of the at least one slot based on the determined CR being less than or equal to a CR threshold value. The at least one weighting factor may be applied to the one or more resources in each of multiple slots scheduled for transmission of a PSSCH.

Channel occupancy ratio calculation

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive at least one sidelink communication on a sidelink, wherein the at least one sidelink communication includes at least one of a grant, data received on a resource identified by a grant, a multi-stage grant, a multi-packet grant, or a relaying communication; and transmit, on the sidelink or an uplink, a feedback message including a plurality of acknowledgements in connection with receiving the at least one sidelink communication. Numerous other aspects are provided.
