    Abstract: Aspects of the disclosure relate to sidelink discontinuous reception (DRX) procedures for blind sidelink retransmissions. A first device may obtain a set of sidelink communication parameters that are associated with a second device. Based at least in part on the set of sidelink communication parameters, the first device may transmit to the second device a sidelink blind retransmission configuration. This configuration may include enablement of sidelink blind retransmission and/or establishment of a number of sidelink blind retransmissions. Other aspects, examples, and features are also claimed and described.

    Abstract: The disclosure relates in some aspects to enabling a user terminal (UT) to obtain information about nearby cells and any beams generated by nearby cells. For example, a network can send a neighbor cell list to UTs, where the list identifies the cells in that neighborhood and provides information about any beams generated by those cells. Thus, a UT can learn the neighboring beams/cells that the UT can reselect to if the current beam/cell becomes weak. In some aspects, the UE can learn the attitude (e.g., pitch, roll, yaw, or any combination thereof) profile of neighboring satellites as well as the pointing angles and the ON-OFF schedules of their beams. In some aspects, the UT can learn a start angle and a span for a satellite and use this information to identify a satellite the UT can reselect to if the current beam/cell becomes weak.

    Abstract: Certain aspects of the present disclosure provide techniques for configuring discontinuous reception on a sidelink connection between a remote user equipment (UE) and a relay UE. An example method generally includes determining a configuration for sidelink discontinuous reception (DRX) communications between the relay UE and a first remote UE, the configuration including a transmission configuration for communications from the relay UE to the first remote UE and a reception configuration for communications from the first remote UE to the relay UE; transmitting, to the first remote UE, a configuration message indicating the configuration for sidelink DRX communications between the relay UE and the first remote UE; and communicating with the first remote UE via a sidelink channel based on the configuration.

    Abstract: Methods, systems, and devices for wireless communications are described. A UE may determine a set of resources available for transmission of one or more reference signals (e.g., one or more PRSs) in a shared radio frequency spectrum band (e.g., an unlicensed radio frequency spectrum band) in a time interval for sidelink positioning. The UE may transmit, in a second radio frequency spectrum, a control message reserving the set of resources for the UE to transmit the one or more reference signals in the time interval for sidelink positioning. The UE may transmit the one or more reference signals on the set of resources based on transmitting the control message reserving the set of resources.

    Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, one or more user equipments (UEs) may implement distance-limited sidelink-based ranging techniques. An initiating UE may transmit one or more positioning reference signal (PRS) request messages to one or more target UEs via a sidelink channel. In some cases, the initiating UE may receive one or more response messages from at least one target UE that is located within a threshold distance from the initiating UE. In some examples, based on receiving the one or more response messages, the initiating UE may transmit PRSs to each target UE that transmitted a response message.

    Abstract: Techniques are discussed herein for detecting anomalous signals such as spoofed satellite positioning system (SPS) signals and for the transmission of accurate location estimates between user equipments (UEs) when the SPS signals are not reliable. A UE determines an SPS derived location estimate and determines an associated confidence level. The confidence level is determined based on time or location derived from the SPS signals, e.g., relative to local time or non-SPS information, such as stored previous location estimates, non-SPS sensor information, and location information from other UEs. The UE transmits location information to other UEs that includes a selected location estimate, confidence level, and the source of the location estimate, e.g., where the SPS derived location estimate is selected if the confidence level is high and the non-SPS derived location estimate is selected if the confidence level is low.

    Abstract: Wireless communication systems and methods related to quality of service mapping, are provided. A first user equipment determines a sidelink radio bearer identifier (SLRB ID) for a quality of service (QoS) flow from a plurality of rules. The rules identify different characteristics of the QoS flow. The SLRB ID is inserted into a header of a packet in the QoS flow. The QoS flow is mapped to a radio bearer that is mapped to an L2 link with other radio bearers that are mapped to other QoS flows. The L2 link transmits the radio bearers to a second UE as part of a broadcast, groupcast or unicast sidelink communication. Based on the SLRB ID, the second UE identifies requirements of the QoS flow.
