D2D operation method of terminal in wireless communication system, and terminal using method
Provided are a device to device (D2D) operation method of a terminal in a wireless communication system, and a terminal using the method. In the method, the terminal receives, from another terminal which is the object of a D2D operation, first information and performs the D2D operation on the basis of the first information, wherein the first information indicates a specific resource in which the other terminal cannot receive a signal transmitted from the terminal, and the terminal performs the D2D operation within the remaining resources excluding the specific resource.
1. A method performed by a first user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a second UE, assistance information related to sidelink transmission of the second UE, wherein the assistant information includes information on a specific resource through which the second UE cannot receive the sidelink transmission transmitted from the first UE;
determining a time resource pattern for Physical Sidelink Shared Channel (PSSCH) for the sidelink transmission among remaining resources excluding the specific resource;
transmitting a first sidelink message, to the second UE, using the time resource pattern; and
transmitting a second sidelink message, to the second UE, using the time resource pattern;
wherein the time resource pattern is repeatedly applied only within the remaining time resources within a resource pool excluding the specific the specific resource,
wherein the specific resource includes a resource through which a synchronization signal is transmitted from a base station to the second UE,
wherein the second UE is a remote UE having a limited bandwidth capability, and
wherein the first UE is a relay UE having a greater bandwidth capability than the second UE.
2. A first user equipment (UE) in a wireless communication system, the method comprising:
a transceiver configured for transmitting and receiving radio signals; and a processor operatively coupled to the transceiver,
wherein the processor is adapted to:
receive, from a second UE, assistance information related to sidelink transmission of the second UE, wherein the assistant information includes information on a specific resource through which the second UE cannot receive the sidelink transmission transmitted from the first UE;
determine a time resource pattern for Physical Sidelink Shared Channel (PSSCH) for the sidelink transmission among remaining resources excluding the specific resource;
transmit a first sidelink message, to the second UE, using the time resource pattern; and
transmit a second sidelink message, to the second UE, using the time resource pattern,
wherein the time resource pattern is repeatedly applied only within the remaining time resources within a resource pool excluding the specific the specific resource,
wherein the specific resource includes a resource through which a synchronization signal is transmitted from a base station to the second UE,
wherein the second UE is a remote UE having a limited bandwidth capability, and
wherein the first UE is a relay UE having a greater bandwidth capability than the second UE.
3. An apparatus configured to control a first UE, the apparatus comprising:
at least one processor; and
at least one memory to be operatively connected to the at least one processor and to store instructions,
wherein the at least one processor executes the instructions to:
receive, from a second UE, assistance information related to sidelink transmission of the second UE, wherein the assistant information includes information on a specific resource through which the second UE cannot receive the sidelink transmission transmitted from the first UE;
determine a time resource pattern for Physical Sidelink Shared Channel (PSSCH) for the sidelink transmission among remaining resources excluding the specific resource;
transmit a first sidelink message, to the second UE, using the time resource pattern; and
transmit a second sidelink message, to the second UE, using the time resource pattern;
wherein the time resource pattern is repeatedly applied only within the remaining time resources within a resource pool excluding the specific the specific resource,
wherein the specific resource includes a resource through which a synchronization signal is transmitted from a base station to the second UE,
wherein the second UE is a remote UE having a limited bandwidth capability, and
wherein the first UE is a relay UE having a greater bandwidth capability than the second UE.
