DIRECT COMMUNICATION METHOD AND DIRECT COMMUNICATION DEVICE AND COORDINATOR DEVICE USING THE SAME
First Claim
1. A direct communication method, adapted to a communication device performing a random access, the method comprising:
- a first communication device performing a random access in a contention slot wherein the contention slot comprises a first contention slot with a first transmission power upper bound and a second contention slot with a second transmission power upper bound; and
transmitting wireless signal at any transmission power less than the first transmission power upper bound of the first contention slot or the second transmission power upper bound of the second contention slot in which the first communication device participates in a contention.

Abstract
A direct communication method, a direct communication device, and a coordinator device using the same method are provided. The direct communication method may be adapted for direct communications between devices with multiple priorities/power upper bounds/ranges. Multiple contention/transmission slots with different power upper bounds or priorities are used as a configuration to allocate resource for the direct communication. The associated configuration acquisition is also disclosed. The direct communication method may also adopt relative periodicity of occurrence of the contention/transmission slots, and may adaptively vary the relative periodicity. The direct communication method may include an associated monitor scheme for spectrum regulation.
