The present disclosure relates to the technical field of communications, and disclosed are a resource reservation method and apparatus, a device and a storage medium. The method comprises: once LBT is successful, sending sidelink control information, wherein the sidelink control information is used to indicate N transmission resources reserved for a first transmission block, and the upper limit value of N is an integer greater than 3. Provided in the embodiments of the present application is a method for indicating transmission resources reserved by a terminal device when performing sidelink transmission on the basis of an unlicensed spectrum. Moreover, the sidelink control information sent by the terminal device may indicate more than three transmission resources, so that the reserved transmission resources may be indicated as much as possible in the sidelink control information.

A configuration method for a sidelink relay architecture and a device are disclosed. The method is executed by a relay terminal, and includes: receiving configuration information, where the configuration information is used for configuring a mapping relationship between a universal user network interface Uu bearer and at least one of the following of a remote terminal: a sidelink bearer or quality of service QoS flow information, and the Uu bearer is a bearer between the relay terminal and a network device.

Disclosed are techniques for wireless communication. In an aspect, a position estimation entity provides assistance data to sidelink anchors and a UE. The assistance data may include a set of proximity-based sidelink positioning reference signal (PRS) pre-configurations for on-demand PRS position estimation. The target UE transmits a sidelink PRS trigger to trigger an on-demand sidelink PRS position estimation session with a dynamic sidelink anchor group, the sidelink PRS trigger configured to indicate a sidelink zone associated with the UE and a proximity requirement for participation in the on-demand sidelink PRS position estimation. At least one sidelink anchor determines that the proximity requirement to the sidelink zone is satisfied, selects a proximity-based sidelink PRS pre-configuration based on a dynamic proximity to the sidelink zone, and performs a sidelink PRS exchange with the UE.

Disclosed are techniques for wireless communication. In an aspect, a position estimation entity configures a sidelink anchor group with sidelink anchor(s), to which respective sidelink PRS pre-configuration(s) are sent. A UE transmits a request to schedule an on-demand sidelink PRS position estimation session of the UE. The position estimation entity provides the UE with assistance data associated with the sidelink anchor group for the on-demand sidelink PRS position estimation session. The UE sends the sidelink anchor group a sidelink PRS trigger to perform a sidelink PRS exchange with some or all of the sidelink anchor group in accordance with the respective sidelink PRS pre-configuration(s).

Techniques for wireless communications are described. A first device may receive first control signaling that may indicate a second device in a wireless communications system. The first device may then identify, based on the received first control signaling, a set of devices for tracking the second device in the wireless communications system. In some examples, the first device may then transmit second control signaling to the identified set of devices for tracking the second device in the wireless communications system. The first device may then receive, based on the transmitted second control signaling, coordination information from the set of devices. The received coordination information may be associated with the second device. The coordination information collected by the set of devices may be used to predict changes in an environment surrounding the second device. By predicting dynamic changes in the environment, disruptions in wireless communication may be prevented.

A method and device are disclosed for radio resource allocation to support User Equipment-to-Network (UE-to-Network) relaying. The network node establishes a Radio Resource Control (RRC) connection with a remote UE via a relay UE. The network node transmits a first RRC message to the remote UE via the relay UE, wherein the first RRC message includes a Uu radio bearer configuration and a Sidelink (SL) Radio Link Control (RLC) bearer configuration associated with a data radio bearer (DRB) or a signalling radio bearer (SRB) and wherein the network node is allowed to include a first field used to indicate a configuration for UE autonomous resource selection for sidelink communication transmission in the first RRC message and the network node is not allowed to include a second field used to indicate a configuration for UE to transmit sidelink communication based on network scheduling in the first RRC message.

A method of operating a first device 100 in a wireless communication system is proposed. The method may comprise: generating a MAC PDU related to a groupcast transmission; and selecting at least one SL resource for a transmission of the MAC PDU among a plurality of candidate resources in a resource pool, wherein a first SL resource included in the at least one SL resource is included in a first SL DRX active time, and the first SL resource being selected outside the first SL DRX active time is not allowed, based on the MAC PDU being related to groupcast transmission.

A method for WTRU autonomous resource selection may comprise receiving a TX resource pool for D2D communication from a base station. The WTRU may sense one or more resources of the TX resource pool and determine resources for transmission of control information and D2D data, based on the sensing. The WTRU may then transmit, to another WTRU, the control information and the D2D data on the determined resources.

A method and apparatus are disclosed. In an example from the perspective of a first device, the first device performs sidelink communication with one or more destinations. The first device receives and/or selects a sidelink grant associated with a sidelink transmission. Responsive to the sidelink grant, the first device selects a first destination of the one or more destinations based upon a report signaling. The first device performs the sidelink transmission associated with the sidelink grant to the first destination.
