DISTRIBUTED SCHEDULING METHOD AND APPARATUS FOR RESOURCE ALLOCATION FOR DEVICE-TO-DEVICE COMMUNICATION
First Claim
1. A distributed scheduling method for resource allocation for Device-to-Device (D2D) communication, the method comprising:
- sending, by a Mobile Station (MS) with data to transmit, a first resource reservation message through at least one first slot among a plurality of slots constituting a resource reservation unit in a resource reservation channel; and
when a second resource reservation message sent by another MS is not sensed in a slot with a higher priority than the first slot in the resource reservation unit, transmitting the data through a transmission resource unit corresponding to the resource reservation unit in a data transmission channel;
wherein the resource reservation channel corresponds to the transmission resource unit, and the plurality of slots comprise mutually cyclic priorities.

Abstract
Provided is a distributed scheduling method and apparatus for resource allocation for Device-to-Device (D2D) communication. The method includes sending, by a Mobile Station (MS) including data to transmit, a first resource reservation message through at least one first slot among a plurality of slots constituting a resource reservation unit in a resource reservation channel; and when a second resource reservation message sent by another MS is not sensed in a slot with a higher priority than the first slot in the resource reservation unit, transmitting the data through a transmission resource unit corresponding to the resource reservation unit in a data transmission channel. The resource reservation channel corresponds to the transmission resource unit, and the plurality of slots has mutually cyclic priorities.

11. A Mobile Station (MS) for performing Device-to-Device (D2D) communication, the MS comprising:
-
a message generator configured to generate a first resource reservation message; a data generator configured to generate data to be transmitted; a transmitter configured to, when there is data to be transmitted, send the first resource reservation message through at least one first slot selected from among a plurality of slots constituting a resource reservation unit in a resource reservation channel, wherein the plurality of slots having mutually cyclic priorities; a receiver configured to listen to remaining slots, except for the first slot in the resource reservation unit, to determine whether a second resource reservation message is sent by another MS; and a controller configured to, when no second resource reservation message is sent by another MS in a slot with a higher priority than the first slot in the resource reservation unit, control the transmitter to transmit the data through a transmission resource unit corresponding to the resource reservation unit in a data transmission channel. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
