Methods and apparatuses for controlling and scheduling device-to-device communications

摘要

At least one example embodiment discloses a method of controlling direct user equipment communications. The method includes receiving reports from a first user equipment (UE) and a second UE, respectively, the first and second UEs communicating with a serving base station, determining at least one control channel and at least one data channel for a direct communication between the first UE and the second UE, allocating at least one resource block for the direct communication link between the first UE and the second UE based on the determining and transmitting a configuration message to the first UE and the second UE, the configuration message indicating the allocated resource block and permitting at least one of the first UE and the second UE to determine parameters of the direct communication link.

1. A method of controlling direct user equipment communications, the method comprising:
receiving reports from a first user equipment (UE) and a second UE, respectively, the first and second UEs communicating with a serving base station, each report including a buffer status report (BSR), a buffered waiting time report (BWTR), a common reference signal report (CRSR) and a sounding reference signal report (SRSR) for the respective first or second UE; determining at least one control channel and at least one data channel for a direct communication link between the first UE and the second UE; allocating at least one resource block for the direct communication link between the first UE and the second UE based on the determining; determining a time-division duplex (TDD) transmission duty cycle for the direct communication link based on the buffer status report (BSR), the buffered waiting time report (BWTR), the common reference signal report (CRSR) and the sounding reference signal report (SRSR) in the received reports, the determining the TDD duty cycle being a division of the allocated at least one resource block amongst the first UE and the second UE; and transmitting a configuration message to the first UE and the second UE, the configuration message indicating the allocated resource block and the determined TDD transmission duty cycle and permitting at least one of the first UE and the second UE to adjust parameters of the direct communication link.
