A method and user equipment (UE) are provided. The method includes transmitting, from a first UE, an assistance request to at least one neighboring UE, receiving, by the first UE and from the at least one neighboring UE, assistance information including an indication of at least one resource for transmission, and transmitting, from the first UE, over the indicated at least one resource.

User equipment assistance for resource selection in new radio vehicle to everything

A device may perform a transmission that may occupy at least a portion of a first slot and perform a listen-before-talk (LBT) sensing operation, wherein the LBT sensing operation may occupy at least a portion of an LBT gap, and at least a portion of the LBT gap may occupy at least a portion of a second slot. A device may perform a transmission that may occupy at least a portion of a first slot, transmit an indication of a resource for an LBT sensing operation, perform an LBT sensing operation for the transmission that may occupy at least a portion of a second slot, and transmit, based on the LBT sensing operation, a reservation signal that may occupy at least a portion of the second slot. A device select a resource for a transmission using a sidelink channel, and select a resource for an LBT sensing operation.

Systems, methods, and apparatus for slot structure, channel access, and resource allocation for sidelink communications

A UE apparatus is provided for NR V2X Mode 2 resource selection. The UE apparatus includes a transceiver; and a processor configured to identify a sensing window and a resource selection window, monitor for sidelink control information (SCI) transmitted by neighbor UEs in the sensing window, determine a resource for transmitting data in the resource selection window, and transmit, via the transceiver, data using the determined resource. The sensing window includes a mandated sensing duration for detection of aperiodic traffic prior to transmission by the transceiver.

Power-efficient resource selection procedure for NR V2X UE with limited power

A method and apparatus are provided for pre-emption, congestion control, and transmission (Tx)/reception (Rx) alignment for use by user equipments (UEs) with limited power. The method includes identifying a set of mandatory slots per at least one resource pool or bandwidth part (BWP); monitoring the set of mandatory slots; and receiving transmission (Tx) and reception (Rx) alignment information during at least one of the monitored mandatory slots.

Pre-emption, congestion control, and Tx/Rx alignment for NR V2X UE with limited power

A method and user equipment (UE) are provided. An assistance request is transmitted from a first UE to at least one second UE. Assistance information including an indication of a set of one or more resources for transmission is received by the first UE, from the at least one second UE. It is determined that the set includes a reserved resource. At least one resource, other than the reserved resource, is selected from the set of one or more resources, for transmission by the first UE.

A user equipment (UE) and a method are provided. The UE includes a memory and a processor configured to receive data from at least one neighboring UE; determine, based at least partially on the received data, whether to send an assistance report including assistance information providing an indication related to communication; and transmit the assistance report including the assistance information in response to determining to send the assistance report.

Efficient techniques for resource selection assistance reporting for NR Rel-17 sidelink

A method and apparatus are provided for pre-emption, congestion control, and Tx/Rx alignment for use by a partial sensing UE. A method includes measuring resources within a first window; determining a number of the measured resources having an RSSI greater than a first threshold; determining a CBR based on the measured number of resources; and determining a CR limit based on the determined CBR and transmission priority. Determining the CBR based on the measured number of resources includes comparing a total number of measured resources within the first window to a second threshold; in response to the total number of measured resources being less than the second threshold, determining the CBR as a pre-configured CBR; and in response to the total number of measured resources being greater than or equal to the second threshold, determining the CBR based on a ratio of the number of the measured resources having the RSSI greater than the first threshold to the total number of measured resources within the first window.

A method may include sending a contention resolution message for a random access procedure from a user equipment (UE) through a physical uplink channel in a wireless communication network, and sending a repetition of the contention resolution message from the UE through the physical uplink channel. The physical uplink channel may include a physical uplink shared channel (PUSCH). The method may further include selecting a preamble from a first preamble group corresponding to a capability of the UE to send the repetition of the contention resolution message, and sending the preamble from the UE. Selecting the preamble from the first preamble group may include selecting a preamble from a first preamble sub-group corresponding to the capability of the UE to send the repetition of the contention resolution message.
