Abstract
Embodiments of the present disclosure provide a signal retransmission apparatus and method and a communication system. The method includes: a first UE determines a resource for retransmitting a signal according to a resource for initially transmitting the signal and a frequency hopping pattern; and retransmits the signal to a second UE according to the determined resource. With the embodiments of the present disclosure, interference between UEs may be randomized as possible, and complexity of blind detection by receiver end UE may be lowered as possible.
Claims20
A signal retransmission apparatus, configured in a first UE (user equipment), the apparatus comprising:
- a resource determining unit configured to determine a resource for retransmitting a signal according to a resource for initially transmitting the signal and a frequency hopping pattern;
- and
- a signal transmitting unit configured to retransmit the signal to a second UE according to the determined resource.
A signal retransmission apparatus, configured in a second UE, the apparatus comprising:
- a signal receiving unit configured to receive a signal retransmitted by a first UE;
- wherein a resource for retransmitting the signal is determined by the first UE according to a resource for initially transmitting a signal and a frequency hopping pattern.
A communication system, comprising:
- a first UE configured to determine a resource for retransmitting a signal according to a resource for initially transmitting the signal and a frequency hopping pattern, and retransmit the signal according to the determined resource;
