Abstract:
A relay network and entity capable of successive continuous transmission by using overlapped coding in order to reduce a transmission delay according to the relay use are provided to reduce transmission delay according to the relay use by transmitting data without time division between a base station-relay link and relay-terminal link. A base station(410) reuses a resource allocated to a direct transmission link in the transmission of the base station through an overlapped coding mode. A relay(420) is allocated the resources allocated in the base station and the other separate resources in the transmission of the relay-terminal link. A channel characteristics is maintained in the transmission of the relay-terminal link. The base station-relay link transmits the relay without allocating the resource.
Abstract:
A multiuser power allocating method for multiplex transmission using the overlapped coding of the power allocation priority in a communications system is provided to increase the frequency reuse efficiency by accommodating a plurality of user terminals and dividing power. Power is especially allocated by a user terminal in order that it is satisfied the requirement specification of each user terminal(S202). The power allocation priority is determined in the power allocation according to the channel condition of each user terminal. The power allocation priority is given from the user terminal in which the channel condition is excellent and the user terminal in which the channel condition is bad(S201).
