[1203] According to the first embodiment, the method of inserting a TPC command for D2D into DCI format 3 / 3A masked with TPC-PUCCH-RNTI or TPC-PUSC-RNTI may include (1) a method of continuously occupying some TPC fields and (2) interleaving method (eg, odd-numbered / even-numbered distinction).

[1204] 1) by having TPC commands for D2D positioned after TPC commands for cellular UEs or 2) by having TPC commands for D2D (TPC commands for SA and D2D data) be placed consecutively after TPC commands for cellular UEs After that, TPC commands for D2D can be inserted.

[1205] In the above configuration of the TPC command field of DCI format 3 / 3A, when there is a UE receiving both the cellular TPC command and the D2DTPC command, the cellular TPC command and the D2D TPC command may be preferably combined and included in one DCI format.

[1206] As explained above, this is because when TPC commands for UEs that should receive cellular TPC commands and D2D TPC commands together and UEs t...

Abstract

The present disclosure is characterized by including the steps of obtaining a resource pool for use in D2D communication in a wireless communication system, wherein the resource pool includes at least one of a scheduling assignment (SA) resource pool that represents a resource region to which the SA is transmitted, or a data resource pool that represents a resource region to which D2D data is transmitted; transmitting SA including information related to D2D data transmission to a second terminal through the SA resource pool; and transmitting D2D data to the second terminal.

Description

technical field [0001] The present invention relates to a wireless communication system, and more particularly, to a method of controlling transmission power for Device-to-Device (D2D) communication in a wireless communication system supporting D2D communication. Background technique [0002] Mobile communication systems have been developed to provide voice services while ensuring user's activities. However, the mobile communication system has been extended to the area of ​​data service as well as voice. Nowadays, there is a shortage of resources due to the explosive increase of traffic, and a higher-level mobile communication system is required due to users' demands for higher-speed services. [0003] Requirements for next generation mobile communication systems basically include acceptance of explosive data traffic, significant increase in transfer rate per user, acceptance of significantly increased number of connected devices, very low end-to-end delay, and high energy ...
