Abstract: A device receiving a transmission is configured to provide its feedback in a unique resource pattern within a set of resources (a resource pool). The resource pattern used by the device overlaps partially with one or more resource patterns used for feedback transmissions by other devices in the group. The transmitting device is able to identify the device by identifying an activation pattern matching the unique resource pattern of the device in the overall feedback that it receives from the devices of the group.

Abstract: Embodiments of the present disclosure relate to apparatuses, methods, and computer readable storage media for beam management assistance. A first apparatus receives, from a third apparatus, assistance data for beam alignment with a second apparatus based on measurements from a fourth apparatus, the first apparatus to be communicated with the second apparatus. The first apparatus determines, based on the assistance data and the measurements from the fourth apparatus, a target beam from a plurality of candidate beams of the first apparatus. The first apparatus performs beam management and/or communications with the second apparatus by using the target beam.

Abstract: Example embodiments of the present disclosure relate to a method, apparatus, and computer readable storage medium for resource exclusion. In a method, an apparatus determines at least one resource block (RB) set where a consistent listen before talking (LBT) failure is detected for the at least one RB set. Then, the apparatus determines the number of available candidate resources within a time window where the available candidate resources exclude candidate resources on the at least one RB set within the time window.

Abstract: Systems, methods, and apparatuses for sidelink collision avoidance based on sensing, such as PSFCH sensing, are provided. One method may include sensing, by a first UE, a first sidelink feedback transmission from a second UE in a first PSFCH resource, and determining, based on the first PSFCH resource, a first radio resource in which the second UE received a first data transmission from a third UE. The method may also include sensing a second sidelink feedback transmission from the second UE in a second PSFCH resource, determining, based on the second PSFCH resource, a second radio resource in which the second UE received a second data transmission from the third UE, and determining, based on at least one of the determined first radio resource or second radio resource, a third radio resource in which the second UE is expected to receive a third data transmission from the third UE.

Abstract: Various example embodiments relate to a solution for positioning of a low power device using sidelink peers. A target user device for a locally assisted positioning procedure may receive a trigger event to initiate positioning of the target user device, the trigger event originating from a location management function in relation to the locally assisted positioning procedure. The target user device may transmit at least one local positioning aid request to one or more anchor user devices for the locally assisted positioning procedure, the at least one local positioning aid request indicating a need for the locally assisted positioning procedure for the positioning of the target user device. Devices, methods, and computer programs are disclosed.
