Method for transmitting buffer status report in device-to-device communication, and device thereof
First Claim
1. A method for a first User Equipment (UE) to execute inter-UE direct communication with a second UE, the method comprising:
- transmitting, to at least one of a Base Station (BS) and a radio resource allocation entity, a first signal including radio resource allocation request information for inter-UE direct communication with the second UE;
receiving, from at least one of the BS and the radio resource allocation entity, a second signal including radio resource allocation information, discovery frequency information associated with inter-UE direct communication, and assistance information for inter-UE direct communication, wherein the assistance information includes adjacent UE identification information for identifying at least one UE located within a predetermined distance from the first UE;
executing inter-UE direct communication with the second UE based on the radio resource allocation information; and
transmitting, to at least one of the BS and the radio resource allocation entity, a third signal including information associated with a status of inter-UE direct communication with the second UE,wherein the second signal is transmitted by being included in a system information block; and
wherein the transmitting a third signal includes;
transmitting, by the first UE, the third signal including indication information indicating termination of inter-UE direct communication with the second UE, to allow at least one of the BS and the radio resource allocation entity to release radio resources allocated for inter-UE direct communication between the first UE and the second UE.

Abstract
Provided are a method for transmitting a buffer status report (BSR), and a device thereof, and to: a method by which a first terminal transmits and receives a BSR required for performing device-to-device communication with a second terminal in order to efficiently allocate a wireless resource to be used for the device-to-device communication; and a device therefor. Specifically, provided are a method and a device by which the first terminal performs device-to-device communication with the second terminal. Such a method includes triggering a BSR for the device-to-device communication with the second terminal, transmitting the BSR to a base station or a wireless resource allocation entity, and receiving wireless resource allocation information for the device-to-device communication with the second terminal from the base station or the wireless resource allocation entity.

8. A method for a Base Station (BS) to control inter-User Equipment (UE) direct communication, the method comprising:
-
receiving, from a first UE, a first signal including radio resource allocation request information for inter-UE direct communication; transmitting, to the first UE, a second signal including radio resource allocation information, discovery frequency information associated with inter-UE direct communication, and assistance information for inter-UE direct communication, wherein the assistance information includes adjacent UE identification information for identifying at least one UE located within a predetermined distance from the first UE, and the first UE performs inter-UE direct communication with the second UE based on the radio resource allocation information; receiving, from the first UE, a third signal including information associated with a status of inter-UE direct communication; and releasing radio resources allocated for inter-UE direct communication between the first UE and a second UE when the third signal includes indication information indicating termination of inter-UE direct communication between the first UE and the second UE, wherein the second signal is transmitted by being included in a system information block. - View Dependent Claims (9, 10, 11, 12, 13)

14. A first User Equipment (UE) for performing inter-UE direct communication with a second UE, the first UE comprising:
-
a transmitter configured to transmit, to at least one of a Base Station (BS) and a radio resource allocation entity, a first signal including radio resource allocation request information for inter-UE direct communication with the second UE; a receiver configured to receive, from at least one of the BS and the radio resource allocation entity, a second signal including radio resource allocation information, discovery frequency information associated with inter-UE direct communication, and assistance information for inter-UE direct communication, wherein the assistance information includes adjacent UE identification information for identifying at least one UE located within a predetermined distance from the first UE; and a controller configured to perform inter-UE direct communication with the second UE based on the radio resource allocation information, wherein the second signal is transmitted by being included in a system information block; wherein the transmitter further transmits, to at least one of the BS and the radio resource allocation entity, a third signal including information associated with a status of inter-UE direct communication with the second UE; and wherein the transmitter transmits the third signal including indication information indicating termination of inter-UE direct communication with the second UE, to allow at least one of the BS and the radio resource allocation entity to release radio resources allocated for inter-UE direct communication between the first UE and the second UE. - View Dependent Claims (15, 16, 17, 18, 19, 20)
