US 11,452,002 B2 · Method whereby terminal transmits device-to-device (D2D) signal in wireless communication system that supports D2D communication, and apparatus therefor

Abstract

Disclosed are a method whereby a terminal transmits a device-to-device (D2D) signal in a wireless communication system that supports D2D communication according to various embodiments, and an apparatus therefor. Disclosed are a method whereby a terminal transmits a D2D signal, and an apparatus therefor, wherein the method comprises: a step of measuring a technology congestion level with regard to a predetermined resource area; and a step of determining a wireless technology that is to be used for the 2D2 signal transmission on the basis of the technology congestion level, and transmitting the D2D signal on the basis of the determined wireless technology, and wherein the technology congestion level is related to the proportion of received signals that include information regarding the usage of a particular wireless technology in the predetermined resource area.

Dependent claims

A method of transmitting a sidelink signal by a user equipment (UE) in a wireless communication system supporting sidelink communication, the method comprising:

configuring a resource pool for the sidelink signal;
receiving a plurality of Physical Sidelink Control Channels (PSCCHs) in the resource pool for a predetermined period;
measuring a congestion level based on the received plurality of PSCCHs;
selecting transmission resources for a transmission of the sidelink signal within the resource pool;
and
transmitting the sidelink signal in the transmission resources based on the congestion level,
wherein the congestion level is a ratio of PSCCHs to which a transmit diversity (TxD) transmission scheme is applied among the plurality of PSCCHs, and
wherein the sidelink signal is transmitted by applying the TxD transmission scheme based on the ratio of PSCCHs to which the TxD transmission scheme greater than a predetermined threshold.
