Various examples and schemes pertaining to partial sensing enhancement for sidelink (SL) resource allocation in New Radio (NR) vehicle-to-everything (V2X) communications are described. A user equipment (UE) performs one-shot sensing and periodic sensing prior to a transmission. The UE selects a resource based on results of the one-shot sensing and the period sensing. Then, the UE performs the transmission using the selected resource in a SL communication in a V2X network.

Partial sensing enhancement for sidelink resource allocation

Various examples and schemes pertaining to sidelink resource allocation for vehicle-to-everything (V2X) in New Radio (NR) mobile communications are described. An apparatus implemented in a first user equipment (UE) receives a first signaling from a network node of a wireless network, with the first signaling configuring a first sidelink resource for a sidelink between the first UE and a second UE. The apparatus transmits a packet or transport block (TB) to the second UE on the sidelink using the configured first sidelink resource. The apparatus also receives a second signaling from the network node responsive to the second UE failing to decode the packet or TB, with the second signaling dynamically configuring a second sidelink resource for the sidelink. The apparatus then retransmits the packet or TB to the second UE on the sidelink using the dynamically configured second sidelink resource.

Various examples and schemes pertaining to on-demand network configuration of vehicle-to-everything (V2X) user equipment (UE) autonomy in New Radio (NR) mobile communications are described. An apparatus implemented in a first user equipment (UE) receives a signaling from a network node of a wireless network. Based on the signaling, the apparatus operates simultaneously in a network-controlled mode and an autonomous mode such that: (a) the first UE operates in the network-controlled mode with respect to resource allocation on a first sidelink with a second UE, and (b) the first UE operates in the autonomous mode with respect to resource allocation on a second sidelink with the second UE or a third UE.

Various examples and schemes pertaining to resource allocation in presence of in-band emission (IBE) for New Radio (NR) vehicle-to-everything (V2X) mobile communications are described. An apparatus implemented in a user equipment (UE) identifies a first resource of a plurality of resources used by another UE in a vehicle-to-everything (V2X) communication environment. The apparatus selects a second resource of the plurality of resources adjacent to the first resource. Then, the apparatus performs transmission in the second resource.

Various examples and schemes pertaining to methods and apparatus of a New Radio (NR) vehicle-to-everything (V2X) cluster head are described. An apparatus implemented as a source user equipment (UE) determines whether there is a need to either join a cluster or become a cluster head in an NR V2X communication environment. The apparatus also detects whether there is any existing cluster head in the NR V2X communication environment responsive to determining that there is the need. The apparatus then determines whether to join a first cluster associated with a first cluster head responsive to the first cluster head being detected as an existing cluster head in the NR V2X communication environment.

An apparatus, implemented in a user equipment (UE) of a V2X cluster in an NR V2X communication environment, receives a scheduling request from a member of the V2X cluster. The apparatus transmits a resource grant to the member to allocate a resource of one or more resources to the member responsive to the receiving of the scheduling request. The one or more resources are either: (a) preconfigured by a wireless network, or (b) granted by the wireless network responsive to the UE transmitting a resource request to the wireless network upon receiving the scheduling request.
