Abstract
The present disclosure provides a method for determining a resource of a communication by a terminal in a wireless communication system, the method comprising: receiving, from a base station, information on a minimum number of subframes for monitoring; determining a number of a plurality of subframes to be monitored based on the minimum number of subframes; identifying the plurality of subframes to be monitored for a sidelink transmission; and transmitting, to the base station, information indicating a set of subframes for the sidelink transmission selected based on the plurality of subframes.
Claims8
A method for determining a resource of a communication by a terminal in a wireless communication system, the method comprising:
- receiving, from a base station, information indicating a minimum number of subframes for monitoring;
- determining a number of a plurality of subframes to be monitored based on the minimum number of subframes, the number of the plurality of subframes being greater than or equal to the minimum number of subframes for monitoring;
- determining the plurality of subframes to be monitored in a predetermined time interval based on the determined number of the plurality of subframes to be monitored;
- monitoring the plurality of subframes by measuring a sidelink-received signal strength indicator (S-RSSI) of a sidelink signal received in each of the plurality of subframes;
- determining, among the plurality of subframes, a subframe to be included in a set of subframes for a sidelink transmission based on the S-RSSI measured in each of the plurality of subframes;
- and
- transmitting, to an upper layer of the terminal, information indicating the set of subframes for the sidelink transmission.
A terminal for determining a resource of a communication in a wireless communication system, the terminal comprising:
- a transceiver configured to transmit and receive signals;
- and
- a controller coupled with the transceiver and configured to control to:
- receive, from a base station, information indicating a minimum number of subframes for monitoring,
- determine a number of a plurality of subframes to be monitored based on the minimum number of subframes, the number of the plurality of subframes being greater than or equal to the minimum number of subframes for monitoring,
- determine the plurality of subframes to be monitored in a predetermined time interval based on the determined number of the plurality of subframes to be monitored,
- monitor the plurality of subframes by measuring a sidelink-received signal strength indicator (S-RSSI) of a sidelink signal received in each of the plurality of subframes,
- determine, among the plurality of subframes, a subframe to be included in a set of subframes for a sidelink transmission, based on the S-RSSI measured in each of the plurality of subframes, and
- transmit, to an upper layer of the terminal, information indicating the set of subframes for the sidelink transmission.
A method for receiving information on a resource of a communication by a base station in a wireless communication system, the method comprising:
- transmitting, to a terminal, information indicating a minimum number of subframes for monitoring;
- and
- receiving, from the terminal, information indicating a set of subframes for a sidelink transmission, wherein the set of subframes for the sidelink transmission is determined based on the minimum number of subframes for monitoring,
- wherein a subframe among a plurality of subframes is determined to be included in the set, based on a sidelink-received signal strength indicator (S-RSSI) measured in each of the plurality of subframes, and
- wherein the plurality of subframes are determined based on a number of the plurality of subframes that is greater than or equal to the minimum number of subframes for monitoring.
A base station for receiving information on a resource of a communication in a wireless communication system, the base station comprising:
- a transceiver configured to transmit and receive signals;
- and
- a controller coupled with the transceiver and configured to control to:
- transmit, to a terminal, information indicating a minimum number of subframes for monitoring, and
- receive, from the terminal, information indicating a set of subframes for a sidelink transmission,
- wherein the set of subframes for the sidelink transmission is determined based on the minimum number of subframes for monitoring,
- wherein a subframe among a plurality of subframes is identified to be included in the set, based on a sidelink-received signal strength indicator (S-RSSI) measured in each of the plurality of subframes, and
- wherein the plurality of subframes are identified based on a number of the plurality of subframes that is greater than or equal to the minimum number of subframes for monitoring.
