摘要： A solution of reconstructing the network topology according to the traffic related information of each cell is proposed in the present invention, so as to achieve self-optimization of network. The traffic related information of a cell includes the traffic related information applicable to network topology reconstruction, or load related information as is named, including but not limited to time-frequency resource related amount that is used by the traffic data in the cell, traffic throughout of each cell or the wireless channel quality of each cell for transmitting traffic data, etc. The solutions in the present invention realize the network topology reconstruction according to traffic related information of multiple cells, therefore the network capacity and service quality could be effectively improved and the wireless relay communication network is applicable to those areas with unpredictable traffic distribution. And the network topology reconstruction function in the present invention can simplify network planning and network management, so that network deployment cost and maintenance and management expenses could be saved.

摘要： The present invention discloses a method and a base station for allocating bandwidth for subscriber stations and a backhaul station through taking into joint consideration uplink and down bandwidth requests from respective subscriber stations in a wireless single-hop self-backhaul network. Upon receipt of information on bandwidth requests from the subscriber stations, the base station takes uplink and downlink bandwidth requests into joint consideration, allocates bandwidth for the subscriber stations and the backhaul station, and then notifies the subscriber stations and the backhaul station. Since bandwidth allocation is no longer based on uplink and downlink resources separately, a relatively high system bandwidth utilization ratio can be achieved and uplink and downlink bandwidth fairness for asymmetric traffic be ensured even if the network is overloaded.

摘要： The present invention discloses a method for implementing relay in a wireless communication network, which method comprises: determining that a present-stage backhaul window for use in the backhaul of a present-stage service has started; and switching from a first frequency to a second frequency to complete the backhaul of the present-stage service. The present invention further discloses a repeater for implementing relay in a wireless communication network, which repeater comprises: means for determining that a present-stage backhaul window for use in the backhaul of a present-stage service has started; and means for switching from a first frequency to a second frequency to complete the backhaul of the present-stage service. According to the present invention, each repeater has its own independent frame whose length is the same as the length of that of the base station. Therefore, the present invention is suitable for network applications with high density and heavy traffic.
