摘要

Provided are a method for performing wireless communication by a first device, and a device for supporting the method. The method may comprise: receiving, from a base station, information related to a physical uplink control channel (PUCCH) resource for reporting hybrid automatic repeat request (HARQ) feedback information and information related to a configured grant (CG) resource for sidelink (SL); generating ACK information, based on no physical sidelink control channel (PSCCH) transmission by the first device on the CG resource in a single period; and determining a priority value of the ACK information, wherein the priority value of the ACK information is same as a largest priority value among at least one possible priority value related to the CG resource.

說明書

For example, the UE 1 may select a resource unit corresponding to a specific resource in a resource pool which implies a set of series of resources. In addition, the UE 1 may transmit a SL signal by using the resource unit. For example, a resource pool in which the UE 1 is capable of transmitting a signal may be configured to the UE 2 which is a receiving UE, and the signal of the UE 1 may be detected in the resource pool.

Herein, if the UE 1 is within a connectivity range of the BS, the BS may inform the UE 1 of the resource pool. Otherwise, if the UE 1 is out of the connectivity range of the BS, another UE may inform the UE 1 of the resource pool, or the UE 1 may use a pre-configured resource pool.

In general, the resource pool may be configured in unit of a plurality of resources, and each UE may select a unit of one or a plurality of resources to use it in SL signal transmission thereof.

Hereinafter, resource allocation in SL will be described.

FIG. 10 shows a procedure of performing V2X or SL communication by a UE based on a transmission mode, based on an embodiment of the present disclosure. The embodiment of FIG. 10 may be combined with various embodiments of the present disclosure. In various embodiments of the present disclosure, the transmission mode may be called a mode or a resource allocation mode. Hereinafter, for convenience of explanation, in LTE, the transmission mode may be called an LTE transmission mode. In NR, the transmission mode may be called an NR resource allocation mode.
