Abstract
One embodiment of the present invention relates to a method for a device-to-device (D2D) terminal to transmit a physical sidelink shared channel (PSSCH) in a wireless communication system, the method comprising: a step in which the terminal selects one or more resource blocks to transmit the PSSCH in a subchannel; and a step in which the terminal transmits the PSSCH via the selected one or more resource blocks, wherein the number of the selected one or more resource blocks is the largest value, among values corresponding to the products of the respective exponentiation values of 2, 3, and 5, which does not exceed the number of all resource blocks available for PSSCH transmission in the subchannel.

A method of transmitting a PSSCH (Physical Sidelink Shared Channel), which is transmitted by a D2D (Device-to-Device) user equipment (UE) in a wireless communication system, comprising the steps of:
- determining, by the UE, a greatest value not exceeding the total number of resource blocks usable for transmitting the PSSCH on one or more subchannels among values calculated from 2α1·3α2·5α5, where each of α2, α3, α5 is a non-negative integer,
- transmitting, by the UE, the PSSCH via RBs (resource blocks) corresponding to the greatest value,
- wherein, based on that RBs of the PSSCH and RBs of a PSCCH (Physical sidelink Control Channel) are consecutive, the number of RBs used for a transmission of the PSCCH is excluded from total number of RBs of the one or more subchannels to determine the total number of RBs usable for transmitting the PSSCH.
A D2D (Device-to-Device) user equipment (UE) transmitting a PSSCH (Physical Sidelink Shared Channel) in a wireless communication system, comprising:
- a transmitter and a receiver;
- and
- a processor, the processor configured to determine a greatest value not exceeding the total number of resource blocks usable for transmitting the PSSCH on one or more subchannels among values calculated from 2α1·3α2·5α5, where each of α2, α3, α5 is a non-negative integer,
- wherein the processor is configured to transmit the PSSCH via RBs (resource blocks) corresponding to the greatest values,
- wherein, based on that RBs of the PSSCH and RBs of a PSCCH (Physical sidelink Control Channel) are consecutive, the number of RBs used for a transmission of the PSCCH is excluded from total number of RBs of the one or more subchannels to determine the total number of RBs usable for transmitting the PSSCH.
