Abstract: For congestion control is an important aspect for PC5-based vehicle-to-everything (V2X) communication, a channel occupancy ratio (CR) has been introduced. CR is defined as the total number of sub-channels used by a user equipment (UE) for its transmissions divided by the total number of configured sub-channels over a measurement period of 1000 ms. The present invention provides a method and apparatus for calculating a CR over past multiple N subframes up to a subframe at which data is to be transmitted in sidelink. Accordingly, new sidelink transmission (or retransmission) can be considered for CR measurement.

Abstract: The present invention provides a method for transmitting a signal between terminals, and an apparatus for the same. Specifically, a first terminal performs resource sensing within a resource search section including a plurality of resource units. The first terminal selects a specific resource unit for transmitting the signal on the basis of the result of the resource sensing, and transmits the signal via the specific resource unit by means of a first reference signal sequence. The specific resource unit is a resource occupied by a second terminal, and the first reference signal sequence may be determined on the basis of a second reference signal sequence of the second terminal.
