Abstract
Disclosed are operation methods of communication node supporting direct communications in network. The operation method comprises obtaining scheduling information configured for the direct communications from a first base station; identifying modulation and coding scheme (MCS) information and radio resource information included in the scheduling information; and transmitting, to a second UE, a first message to which a MCS indicated by the MCS information is applied through radio resources indicated by the radio resource information. Therefore, performance of a communication system can be enhanced.
Claims11
An operation method of a user equipment (UE) in a communication system, the operation method comprising:
- receiving, from a base station, a signaling message indicating a speed threshold and a first modulation and coding scheme (MCS) range which is used when a speed of the UE is above the speed threshold;
- determining a MCS value within the first MCS range;
- and
- performing a transmission process using the determined MCS value,
- wherein the signaling message further indicates a second MCS range which is used when the speed of the UE is below the speed threshold, and the MCS value is determined within the first MCS range or the second MCS range.
An operation method of a base station in a communication system, the operation method comprising:
- determining a speed threshold;
- determining a first modulation and coding scheme (MCS) range which is used when a speed of a user equipment (UE) is above the speed threshold;
- generating a signaling message indicating the speed threshold and the first MCS range;
- and
- transmitting the signaling message to the UE,
- wherein the signaling message further indicates a second MCS range which is used when the speed of the UE is below the speed threshold.
