摘要： A relay method and device, wherein the control signal and the data signal which are in the same subframe are directly sent to a lower level device respectively by an upper level device and a relay function device. In one example, the relay function device transmits data signal using subscriber special reference signal to make the lower level device estimate an access channel correctly; in another example, the relay function device carries out precoding of the data signal correlative with the access channel so as to cancel the influence of the access channel, thereby make the lower level device receive data signal correctly. Retransmission control signaling is sent to the lower level device in each subframe by the upper level device to ensure the fixed sequential relationship of feedback retransmission.

摘要： The present invention provides a novel base station, a novel user equipment and a method of reducing energy consumption in a base station. According to the present invention, when detecting no user service for a time period, the base station switches off its transmitter and keeps its receiver switched on, thereby entering into a sleep state; when receiving a wake-up signal, the base station switches on the transmitter, thereby entering into a wake-up state. The method switches off the transmitter to reduce energy consumption when there is no user service, and wakes up the base station intelligently when a user comes.

摘要： The present invention discloses a method of requesting resource from a resource allocating apparatus by a request requesting apparatus, a resource allocating apparatus, a resource requesting apparatus and a communication system. The method comprises the following steps: sending a resource request message from the resource requesting apparatus to the resource allocating apparatus; after receiving the resource request message, if resource cannot be allocated within a set time interval with respect to the resource requesting apparatus, sending an acknowledgement for the resource request message from the resource allocating apparatus to the resource requesting apparatus; and if the resource is allocated to the resource requesting apparatus within the set time interval, not sending the acknowledgement for the resource request message from the resource allocating apparatus to the resource requesting apparatus. Utilizing the method and structure of the present invention, the resource allocating apparatus sends additional acknowledgement message only if needed, therefore overhead is reduced much more. Moreover, since the solution of the present invention does not change any signaling exchanged between the resource allocating apparatus and the resource requesting apparatus, it is able to meet the requirement of backward compatibility.

摘要： The present invention provides a novel adaptive power configuration method and corresponding base stations in a Het Net. According to the present invention, some specific subframes of a serving base station are scheduled to serve victim UEs, while the corresponding subframes of an aggressor base station can be scheduled to serve its UEs with adaptively adjusting the transmit power instead of thoroughly muting. This adaptive power configuration scheme can efficiently reduce the interference in Het Nets to guarantee the workability of victim UEs, meanwhile more capacity performance gain can be achieved with backward compatibility to legacy UEs.

摘要： The present invention provides a method and a device for adjusting the sleep mode of a mobile station in order to solve the problem in current multi-hop relay systems of long time delays in data transmission caused when data packets have to wait for the next listening window to reach the mobile station because of packet errors. Wherein, a relay apparatus judges whether the previous hop network apparatus needs to retransmit data packets to the mobile station; when the previous hop network apparatus needs to retransmit data packets to the mobile station, the relay apparatus transmits to the mobile station the adjustment related information for adjusting the sleep mode of the mobile station. The mobile station adjusts the sleep mode according to the adjustment related information. Preferably, the adjustment related information comprises indicating information for indicating that the mobile station is in triggered listening status within predetermined time interval. In addition, the relay apparatus may also report the adjustment related information to the previous hop network apparatus. The technical solution provided by the present invention obtains shorter time delays, utilizes wireless resources efficiently, and decreases demand on relay apparatus.
