    摘要： A joint channel correction method, an apparatus, and a system are disclosed. The joint channel correction method includes: sending a first joint channel correction instruction to a first RRU; sending a second joint channel correction instruction to a second RRU; receiving a result sent by the second RRU about reception of the first correction reference signal through X2 receive channels in X2 traffic channels; receiving a result sent by the first RRU about reception of the second correction reference signal through X1 receive channels in X1 traffic channels; and obtaining correction compensation coefficients of the X1 traffic channels and/or the X2 traffic channels through calculation according to the first correction reference signal, the result about reception of the first correction reference signal through the X2 receive channels, the second correction reference signal, and the result about reception of the second correction reference signal through the X1 receive channels. Technical solutions provided by embodiments of the present invention help implement channel correction between RRUs without a channel self-correction function.

    摘要： Increased resource utilization efficiency can be improved by modeling path costs during admission and path-selection. Specifically, path costs for candidate paths are modeled based on load characteristics (e.g., current load, load variation, etc.) of links in the candidate paths. Path costs can represent any quantifiable cost or liability associated with transporting a service flow over the corresponding path. For example, path costs can correspond to a probability that at least one link in the path will experience an outage when transporting the service flow, a price charged by a network operator (NTO) for transporting the traffic flow over the candidate path, or a total network cost for transporting the flow over a candidate path. The candidate path having the lowest path cost is selected to transport a service flow.

    摘要翻译： 通过在入场和路径选择期间建模路径成本可以提高资源利用效率。 具体而言，候选路径的路径成本基于候选路径中的链路的负载特性（例如，当前负载，负载变化等）来建模。 路径成本可以表示与在相应路径上传输服务流相关的任何可量化的成本或责任。 例如，路径成本可以对应于以下概率：路径中的至少一个链路将在运输服务流时经历中断，由网络运营商（NTO）收取用于在候选路径上传输业务流的价格，或者 在候选路径上传输流量的总网络成本。 选择具有最低路径成本的候选路径来传输服务流。

    摘要： Systems and methods for computing and/or utilizing mutual information based link metrics for a link in a wireless mesh network are disclosed. In one embodiment, one or more mutual information values are computed for a link between a transmitter of a first network node and a receiver of a second network node in a wireless mesh network. Each of the one or more mutual information values is computed for a different hypothesized transmission mode for the link. One or more link metrics for the link are computed as a function of the mutual information values, where each link metric is computed based on a different one of the one or more mutual information values. In this manner, a link metric is computed for each of the one or more hypothesized transmission modes for the link. At least one of the link metrics are then provided to a routing update module.

    摘要： The present invention provides a method for updating a system message, where an eNB performs a communication resource negotiation with a neighboring eNB to obtain an available subframe, sends a paging message including a system message update indication to a UE, and sends a system message update indication message to the UE in the available subframe. The present invention further provides a communication system and an eNB. By using the method for updating a system message, the communication system, and the eNB according to the present invention, a message is transmitted in a low-interference available subframe, thereby reducing adverse effects caused by interference and improving accuracy of system message update.

    摘要： A wireless communication network (10) includes a plurality of mobile nodes (12a-h) each including a transceiver (14), a phased array antenna (16) connected to the transceiver, and a controller (18) connected to the transceiver. The controller (18) discovers routes and routes communications to neighboring nodes (12a-h) with a routing protocol, e.g. an Optimized Link State Routing (OLSR) protocol. The controller (18) schedules time slots to establish a communication link (18e) with each neighboring mobile node (12), and the phased array antenna (16) is aimed (18c) by the controller (18) towards each neighboring mobile node (12) during communication therewith. Also, the controller estimates link quality (18h) based upon the quality of each time slot scheduled for the communication link and reports estimated link quality to the routing protocol (18i).
