Methods, systems, and devices for wireless communications are described that support sidelink cancellation for out of coverage user equipment. Described techniques provide for signaling of cancellation indications to a user equipment (UE) or a group of UEs to refrain from performing sidelink communications on a set of resources. A base station may transmit a cancellation indication to one or more sidelink UEs via an access link that indicates that an allocation of one or more resources for sidelink communications has been canceled. A first UE may receive the cancellation indication from the base station via the access link and transmit a sidelink communication to one or more other UEs that indicates the canceled resource allocation. Based on the sidelink communication of the cancellation indication from the first UE, the one or more other UEs may refrain from transmitting using the canceled resources.

Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a user equipment (UE) may include sensing an interference level of at least one frequency, selecting, based on the interference level, a frequency, and communicating sidelink control information (SCI) in the selected frequency.

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive control signaling indicating a plurality of component carriers of a sidelink channel and a plurality of feedback channel configurations for the plurality of component carriers. The UE may select, based at least in part on the plurality of feedback channel configurations, a subset of the plurality of component carriers for transmission of a first sidelink message and a second sidelink message using a feedback channel alignment rule indicating to select component carriers having feedback channels aligned in time for at least a subset of a plurality of transmission time intervals. The UE may transmit the first sidelink message on a first component carrier of the subset and the second sidelink message on a second component carrier of the subset.

Wireless communications systems and methods related to channel occupancy time-sharing information (COT-SI) reservation of a COT for sidelink communications in an unlicensed band are provided. In some aspects, a user equipment (UE) performs a channel access procedure to acquire one or more COTs in a sidelink channel over an unlicensed new radio (NR) band. Further, the UE transmits a COT sharing information (COT-SI) configured to reserve the one or more COTs for a future transmission via the sidelink channel.

A method and apparatus are disclosed for a device to perform sidelink communication. The device triggers or requests to perform partial sensing-based resource selection in a first Transmission Time Interval (TTI) in a sidelink resource pool. The device also derives or determines a set of candidate TTIs within a resource selection window in response to the trigger or request, wherein sidelink resources in the set of candidate TTIs are candidate sidelink resources. Furthermore, when the device does not perform sensing in a second TTI, the device excludes a number of candidate sidelink resources, from the candidate sidelink resources, associated with the second TTI, wherein the second TTI is after the first TTI and before the first candidate TTI of the set of candidate TTIs. The device further derives or determines a set of sidelink resources, from the candidate sidelink resources at least excluding the number of candidate sidelink resources.

According to one embodiment of the present disclosure, a method by which a first apparatus performs sidelink communication is provided. The method comprises the steps of: determining a candidate transmission resource related to the first slot, on the basis of sensing not being performed on a first slot; and transmitting, to a second apparatus, at least one PSCCH or at least one PSSCH related to the at least one PSCCH, on the basis of remaining candidate transmission resources, excluding the candidate transmission resource, from among a plurality of candidate transmission resources, wherein the candidate transmission resource can be determined on the basis of the first slot and the relative position on the time axis of a time resource section of the candidate transmission resource.

Disclosed are a method and device for a terminal to perform a beam management operation in a wireless communication system supporting sidelink according to various embodiments. Disclosed are a method and a device for same, the method comprising the steps of: acquiring, from a second terminal, a measurement value indicating the quality of a beam pair in which a sidelink signal is transmitted and received; and determining whether to perform a beam management operation for the beam pair on the basis of one or more thresholds and the measurement value, wherein each of the one or more thresholds may be set on the basis of at least one among mobility information about the first terminal, the relative speed of the first terminal with respect to the second terminal, the congestion level of a channel, and service characteristics related to the sidelink signal.

The present disclosure relates to a pre-5G or 5G communication system to be provided for supporting higher data rates Beyond 4G communication system such as LTE. Embodiments of the present application provide a method and a device for resource allocation. The method includes: initiating initial resource selection for temporarily selecting resources for data to be transmitted; performing a first resource reselection after initial resource selection is initiated and before UE announces resources, and when a first SCI transmitted by other UE is received and a predefined condition for triggering resource reselection is met, wherein a resource reserved by other UE indicated in first SCI is at least one of resources temporarily selected by UE; transmitting PSCCH or PSSCH on first resource according to a result of first resource reselection, and announcing other resources except first resource through transmitted SCI.
