Apparatus and method for avoiding collision between random access transmission and device to device transmission in communication system supporting device to device scheme
A method for avoiding a collision between a device to device (D2D) transmission and a random access transmission by a user equipment (UE) in a communication system supporting a D2D scheme is provided. The method includes detecting resource configuration information related to a random access transmission and resource configuration information related to a D2D transmission, determining a result on whether a resource in which a D2D resource which corresponds to the resource configuration information related to the D2D transmission is included includes a random access resource which corresponds to the resource configuration information related to the random access transmission, and avoiding using the resource or the random access resource for the D2D transmission based on the determined result.
1. An operating method of a user equipment (UE) in a communication system, the operating method comprising:
receiving configuration information associated with a random access resource;
receiving configuration information associated with a resource pool for transmitting a discovery signal; and
selecting, in a discovery period, a resource for transmitting the discovery signal from the resource pool,
wherein the resource is not overlapped with the random access resource.
2. The operating method of claim 1 , wherein the random access resource includes a physical random access channel (PRACH) resource.
3. The operating method of claim 1 , wherein the UE supports a sidelink.
4. The operating method of claim 1 , wherein the configuration information associated with the random access resource includes configuration information associated with a physical random access channel (PRACH).
5. The operating method of claim 1 , further comprising transmitting the discovery signal through the resource.
6. A user equipment (UE) in a communication system, the UE comprising:
at least one processor configured to:
receive configuration information associated with a random access resource,
receive configuration information associated with a resource pool for transmitting a discovery signal, and
select, in a discovery period, a resource for transmitting the discovery signal from the resource pool,
wherein the resource is not overlapped with the random access resource.
7. The UE of claim 6 , wherein the random access resource includes a physical random access channel (PRACH) resource.
8. The UE of claim 6 , wherein the UE supports a sidelink.
9. The UE of claim 6 , wherein the configuration information associated with the random access resource includes configuration information associated with a physical random access channel (PRACH).
10. The UE of claim 6 , further comprising:
a transceiver configured to transmit the discovery signal through the resource.
