According to the present invention, a method performed by user equipment is provided. The method is characterized by including: determining N PSFCHs, and performing one or more PSFCH-related operations, wherein N is an integer greater than or equal to 2, each of the N PSFCHs is for transmission or reception and overlapped in time, and destination layer-1 identifiers in SCI for scheduling data transmission triggering the N PSFCHs are different from each other.

Methods, systems, and devices for wireless communications are described. In some systems, a first user equipment (UE) and a second UE may communicate in accordance with a sidelink resource allocation Mode 1 according to which the UEs may receive scheduling information from a base station. The first UE may receive first-stage sidelink control information (SCI-1) from the second UE based on a destination filter indicator associated with one or more intended receivers of a message scheduled by the SCI-1. The first UE may decode the SCI-1 and determine, based on the destination filter indicator conveyed by the SCI-1, whether the first UE is an intended receiver of the message scheduled by the SCI-1. If the first UE is an intended receiver, the first UE may decode the message. If the first UE is not an intended receiver, the first UE may refrain from decoding the message.
