METHOD AND APPARATUS FOR DEVICE TO DEVICE COMMUNICATION IN A WIRELESS COMMUNICATION SYSTEM AND RELATED APPARATUS USING THE SAME

摘要

The disclosure is directed to a method and apparatus for D2D communication in a wireless communication system and related apparatuses using the same. In one of the exemplary embodiments, a proposed method may include determining whether to performing a D2D transmission and a cellular transmission simultaneously in a resource block allocated in a cellular uplink time slot; if a cellular uplink transmission rate in addition to a D2D transmission rate is greater than or equal to a maximum cellular UL transmission rate: performing the D2D transmission and the cellular transmission simultaneously; and adjusting a power of the D2D transmission and a power of the cellular transmission to maximize an overall transmission rate which is the cellular UL transmission rate in addition to the D2D transmission rate.

1. A method and apparatus for device to device (D2D) communication in a wireless communication system applicable to a user equipment (UE), the method comprising:
determining whether to perform a D2D transmission and a cellular transmission simultaneously in a resource block allocated in a cellular uplink time slot; if a cellular uplink (UL) transmission rate (RUL) in addition to a D2D transmission rate (RD2D) is greater or equal to a maximum cellular UL transmission rate (RC):
performing the D2D transmission and the cellular transmission simultaneously; andadjusting a power of the D2D transmission (PD2D) and a power of the cellular transmission (PUL) to maximize an overall transmission rate which is the cellular UL transmission rate in addition to the D2D transmission rate; and if the cellular UL transmission rate (RUL) in addition to the D2D transmission rate (RD2D) is less than the maximum cellular UL transmission rate (RC), performing the D2D transmission and the cellular transmission in different resource blocks.
