    摘要： Provided is a method of processing hybrid automatic repeat request (HARQ) and adaptive transmission of a device-to-device (D2D) link. In the method, an operation method of user equipment (UE) includes (a) receiving an initial transmission mode (TM) and transmission power for the D2D link from a base station, and performing data transmission through the D2D link, (b) determining, at the UE, a TM and transmission power of a succeeding subframe, or receiving a TM control value and a transmission power control value from counterpart UE of the D2D link and determining the TM and the transmission power of the succeeding subframe, and (c) performing the data transmission to the counterpart UE using the determined TM and transmission power. Here, (b) and (c) are repeated.

    摘要： Disclosed is a method for establishing a device-to-device link connection and scheduling for device-to-device communication and terminal relaying. The method for operating a terminal according to the present invention comprises the following steps: receiving information on the establishment of a D2D link; reporting a state of a D2D buffer of the D2D link to a base station; and receiving information on the D2D link resource allocation based on the report on the D2D buffer state. The scheduling method for D2D communication according to the present invention enables dynamic scheduling to be performed on a subframe unit basis, and enables semi-continuous scheduling for continuous data transmission for a D2D communication link.

    摘要： Disclosed is a communication system which transmits Acknowledgement (ACK)/Negative Acknowledgement (NACK) information on downlink data by using an uplink control channel. The communication system individually allocates radio resources for a plurality of slots included in an uplink subframe. Consequently, uplink radio resources may be used freely, and it is even possible to flexibly handle a situation in which the amount of the ACK/NACK information is increased.

    摘要： Provided is a communication system for a multi-cell cooperative communication. A serving base station and at least one neighboring base station may communicate with at least one terminal through mutual cooperation. Each of the serving base station and the at least one neighboring base station may shift a phase of at least one element among elements included in a precoding matrix, using a phase shift matrix, and precode at least one data symbol. A terminal may feed back preferred phase shift matrix information to the serving base station, so that the serving base station and the at least one neighboring base station may adaptively determine a phase shift matrix. The terminal may calculate the phase shift matrix with small calculation amounts. The serving base station, the at least one neighboring base station, and the terminal may pre-store a plurality of candidate matrices with respect to the phase shift matrix.
