Abstract: A method, apparatus, and computer readable storage medium provide sidelink beam alignment between devices. In the context of a method performed by a first user equipment (UE), the first UE causes transmission of a first plurality of reference signals to a second UE to facilitate selection of a first preferred beam among a plurality of beams of the second UE. The method also receives a second plurality of reference signals from the second UE using a plurality of beams of the first UE. The method further includes selecting a second preferred beam from the plurality of beams of the first UE based on the second plurality of reference signals.

Abstract: A user equipment includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the user equipment to: select radio resources for a first sidelink transmission to a first user equipment based on sidelink control information from a second user equipment, the sidelink control information including at least beam information for a second sidelink transmission by the second user equipment; and perform the first sidelink transmission to the first user equipment on the selected radio resources.

Abstract: Example embodiments of the present disclosure relate to a solution of transmitting sidelink (SL) feedback information on non-contiguous resource sets. In this solution, in accordance with a determination that a plurality of feedback transmission occasions for sidelink transmissions are mapped on non-contiguous resource sets, an apparatus determines a group of contiguous resource sets mapped with a subset of the plurality of feedback transmission occasions; and transmits feedback information on the group of contiguous resource sets.

Abstract: An apparatus comprising circuitry configured to: determine whether a resource pool of a group of time slots associated with a first carrier spacing overlaps with a resource pool of a frame associated with a second carrier spacing within a period of time; wherein the first carrier spacing has a higher frequency than the second carrier spacing, and the period of time comprises the group of time slots associated with the first carrier spacing and the frame associated with the second carrier spacing; and perform sensing of at least one time slot of the group of time slots, based on whether the resource pool of the group of time slots associated with the first carrier spacing overlaps with the resource pool of the frame associated with the second carrier spacing within the period of time.

Abstract: There is provided a method, comprising: receiving a first SCI from a first device indicating a first reserved radio resource for transmission by the first device; receiving a second SCI from a second device indicating a second reserved radio resource for transmission by the second device, the first and second reserved radio resource overlapping at least partially; determining a first and second received signal strength associated with the received first and second SCI respectively; determining at least one of a first MCS applied by the first device or a second MCS applied by the second device; determining, based on the first MCS and/or the second MCS, at least one threshold; and determining, based on the at least one threshold and the first and second received signal strengths, whether or not to transmit a resource conflict indication to at least one of the first device or the second device.

Abstract: An SL UE that detects a resource conflict associated with a transmitting UE may be able to indicate this resource conflict by transmitting inter-UE coordination information over a PSFCH resource determined based on a group member ID of the transmitting UE. This may be different from transmitting HARQ feedback via a PSFCH resource determined based on a group member ID of the detecting UE.

Abstract: Embodiments of the present disclosure relate to methods, devices, apparatuses and computer readable storage medium of groupcast for sidelink communication. In example embodiments, at a leader device in a group of devices, an orthogonal sequence and cover code is selected from a first set of orthogonal sequences and a first set of orthogonal cover codes. The first set of orthogonal sequences and the first set of orthogonal cover codes are used for acknowledgement feedback in the group. An indication of the selected orthogonal sequence and cover code is sent to a first member device of a plurality of member devices in the group.

Abstract: A user device may receive from a base station, information indicating that support for a receive limited user device is enabled based on a presence of a threshold number of receive limited user devices within a range of a cell of the base station. A receive limited user device is a user device that is unable to receive a transmission that was transmitted based on one or more communication capabilities of a full set of communication capabilities. The user device may select, in response to receiving the information, one or more communication capabilities to support a receive limited user device. The user device may transmit information using the selected one or more communication capabilities.
