협력멀티포인트송신을위한통신방법이제공된다. 복수의기지국들및 대상단말사이의채널들의상태에따라복수의기지국들을위한코드북들의사이즈들이조절된다. 그리고, 단말은코드북들의사이즈들에대응하는피드백비트수들을갖는채널방향정보를복수의기지국들중 어느하나의기지국으로피드백한다. 이때, 채널방향정보는 PUSCH 또는 PUCCH를통해피드백될수 있다.
Abstract:
다중셀 통신시스템은적어도제1 기지국과제1 단말의페어와제2 기지국과제2 단말의페어를포함한다. 제1 기지국과제2 기지국이간섭제어를수행해야하는경우, 제1 단말은간섭제어와관련된메시지를제1 기지국과제2 기지국사이에서릴레잉한다. 즉, 제1 단말은제1 기지국으로부터제2 기지국으로간섭제어와관련된메시지를전달하고, 제2 기지국으로부터제1 기지국으로간섭제어와관련된메시지를전달한다. 이에따라, 제1 기지국및 제2 기지국은제1 단말을경유하여간섭제어를수행하기위해요구되는메시지들을송/수신할수 있다.

무선통신시스템에서지연을고려한다중노드협력방법을제안한다. 지연속성이유사한상향링크협력단말기들을상향링크협력영역으로구분하도록스케줄링하고상향링크협력영역과비협력영역간간섭을제거하는프레임구조를제안한다. 또한, 다중노드협력적용시발생하는지연속성에따라확장된주기적전치부호를적용하고확장된주기적전치부호를고려한상향링크와하향링크의협력기지국을결정하는방법을제안한다.
Abstract:
Provided is a method of transmitting data based on cooperation between member nodes belonging to a multicast group, wherein the member nodes belonging to the multicast group are configured to receive the same multicast packet, transmit the multicast packet generated through a first communication network to a device cooperating with each other, and then retransmit the multicast packet based on whether one of the member node of the member nodes has completed the reception of the multicast packet.
Abstract:
PURPOSE: A modulation method for nano communication, a demodulation method thereof, and a receiving device thereof are provided to perform the high-dimensional modulation and demodulation in a communication system which uses a nano element. CONSTITUTION: A receiving device for nano communication includes a cathode unit (110) including a nano element (115) and an anode unit (120) which detects electrons emitted from the nano element. The cathode unit is connected to a minus pole of a power source, and receives a radio signal which is modulated according to a predetermined modulating method. The cathode unit includes the nano element which has at least two resonant frequencies which are different from each other, and which includes the nano element which resonates based on the frequency of the radio signal and the resonant frequencies. The anode unit is connected to a plus pole of the power source; detects multiple electrons which are emitted by the resonance of the nano element; and demodulates the radio signal based on the patterns of the multiple electrons. [Reference numerals] (110) Cathode unit; (120) Anode unit; (AA) Electron emission; (BB) Vertical vibration; (CC) Left and right vibration
Abstract:
PURPOSE: A relay unit, a terminal, and a communication method thereof are provided to notify information for spatial dimension to a terminal by allocating independent space based on a transmission or reception pair. CONSTITUTION: When k transmission and reception pairs simultaneously transmit signals, an access unit(803) accesses a code book which individually arrange effective channels in an independent space. The effective channels are arranged according to code words included in the code book. A selection unit(805) selects a code word which indicates the effective channel from the k transmission and reception pairs by using the code book. A transmission unit(807) transmits information for the selected code word to the transmission and reception pair. [Reference numerals] (801) Reception unit; (803) Access unit; (805) Selection unit; (807) Transmission unit; (809) ID allocation unit; (811) Received beamforming vector determination unit
