SIGNAL RETRANSMISSION APPARATUS AND METHOD AND COMMUNICATION SYSTEM

摘要

Embodiments of the present invention provide a signal retransmission apparatus and method, and a communication system. The method comprises: determining a resource for retransmitting a signal according to a resource for initially transmitting the signal and a frequency hopping pattern, and retransmitting the signal to a second user equipment according to the determined resource. The embodiments of the present invention can not only make interference between user equipments as random as possible, but also reduce complexity of blind detection as much as possible for a receiving end user equipment.
