摘要： In order to solve the drawbacks in the prior art, a new technology scheme is provided in the present invention, in which relay stations are introduced to participate in the communication of multiple carriers. The relay station only relays the carriers with had wireless transmission characteristic and controls the transmission of those relayed carrier via a carrier which does not need to be relayed. The relayed carrier is generally a high frequency carrier and the carrier which does not need to be relayed is a low frequency carrier. The base station or the relay station determines a carrier which needs to be relayed for the relay station according to the channel conditions of each carrier. The technology scheme provided by the present invention divides a NLOS (Non-Line-Of-Sight) transmission into at least two LOS transmissions. Therefore, it is easy to extend high frequency carrier to cell edge etc. Meanwhile the mobile terminal does not need extra transmission power to transmit high frequency carrier, so that the fast consumption of the terminal battery power is avoided and the great radiation hazard to the human body is also avoided. The service data and the signaling etc. which has not been relayed will still propagate in the low frequency carrier, so that the time delay resulted from the relay is avoided.

摘要： A new data packet transmission solution is provided in the present invention. Firstly, a source network equipment sends a duplicate of a data packet to a sponsor relay station and other one or more assistant relay stations; then the one or more assistant relay stations transmit the duplicate of the data packet received to the sponsor relay station. After the sponsor relay station receives the duplicate directly transmitted by the source and a plurality of duplicates which are transmitted by one or more assistant relay stations, it applies a joint processing of several duplicates of the data packet, and then transmits the result of the joint processing to a corresponding network equipment. Preferably, after one or more assistant relay stations transmit the duplicates of the data packet to the sponsor relay station, the destination network equipment also receives one or more duplicates, and applies a joint processing of the one or more duplicates and a duplicate of the data packet which is received from the sponsor relay station.

摘要： The present disclosure provides a novel method for feature activation in the Machine Type Communication and a device thereof. According to the present disclosure, the MTC device may actively trigger entry into or exit from a feature state of the MTC device, and inform the network to perform suitable configuration, so as to meet the requirements of the MTC scenario and optimize the network performance. Furthermore, for the Extra Low Power Consumption feature, it is also proposed to set a MTC device specific DRX cycle as its actual cycle such that the actual cycle may be not limited by the system default DRX configuration information. Therefore, power consumption for the MTC device in the Extra Low Power Consumption state may be reduced.
