摘要： The present invention relates to a method of generating neighbor lists in a radio communication network comprising user terminals and base stations defining sectored or omnidirectional radio cells, where communication between user terminals and base stations is arranged to take place over radio channels. The method comprises the steps of: (a) receiving radio channel measurements from at least some of the user terminals; (b) creating a first table by using the measurements received from the user terminals, the first table comprising for at least some of the user terminals the corresponding radio channel measurement in relation to different radio cells; (c) processing the first table to generate a cell coupling matrix indicative of a radio coupling figure between different pairs of cells in the network; and (d) for a certain cell obtaining a neighbor list by determining the radio channel neighbors to be the cells of which the coupling figure with the cell in question is greater than a given threshold.

摘要： A scheme is provided for allocating spectral resource made up of a plurality of resource units in a multiple access wireless link linking a partition of a base station and at least one child user equipment of the partition in a wireless communications network. According to the scheme the same fixed allocation of resource units is made to each user equipment of the network. According to one embodiment a measure of a maximum likely number of child user equipments per partition of the network is determined. Then a fixed allocation of resource units based on the ratio of the number of resource units per unit time to the measure is calculated. Then the same fixed allocation of resource units is allocated to each child user equipment across the network. In one embodiment resource units which are not allocated in the fixed allocation remain unallocated to user equipments. In another embodiment the remaining resource units are allocated among the child user equipments by prioritizing user equipments having a high gain link. Also provided is a communications network and a resource allocation controller for a communications network which use the above scheme.

摘要： Embodiments of the invention relate to cellular wireless networks and are particularly suited to networks including different types of base stations. So-called femtocell types of base stations are typically deployed within a subscriber's premises and operate at low transmit power, providing a very limited area of wireless coverage. A femtocell is typically deployed within the area of wireless coverage of a conventional macrocell, occupying the same frequency spectrum and timeslots as the macrocell. A problem can be presented to a user equipment terminal that is close to the femtocell but unable to gain access to it, because the transmissions from the femtocell may appear as interference to the user equipment terminal, preventing it from accessing the macrocell which it could otherwise access. A cellular wireless network according to an embodiment of the invention employs a method of allocating radio resource to femtocells so that the transmissions from femtocells do not occupy the same radio resource blocks as those used by the macrocell for signalling; embodiments of the invention thereby prevent interference associated with signalling to cause a connection to be lost, or prevent a connection being set up.

摘要： Current deployment methods for fixed wireless access communications networks typically give rise to a trade off between link performance and capacity. It is difficult to maintain specified levels of link performance while maximizing capacity. When a request to change a fixed wireless access network is received, for example, by adding a subscriber, moving a subscriber or adding a sector to a base station, the link performance at each communications link is determined. For example, by measuring the link performance at each link or by predicting or estimating these link performance levels. If the proposed change to the network does not compromise link performance, that is, the predicted or actual link performance levels are greater than a specified level, proposed change is implemented. Otherwise the now subscriber is placed on hold, pending change to the network such as addition of a new base station or sector. Estimates of the link budgets for each communications link are calculated for “worst case” scenario situations. This may be done using known deployment tools. The method is used in conjunction with fixed frequency planning or without fixed frequency planning. In the absence of fixed frequency planning, deployment of the communications network is eased.

摘要： Embodiments of the invention relate to cellular wireless networks and are particularly suited to networks including different types of base stations. So-called femtocell base stations are typically deployed within a subscriber's premises and operate at low transmit power, providing a very limited area of wireless coverage. A femtocell is typically deployed within the area of wireless coverage of a conventional macrocell type of base station, and if handover from a macrocell is performed on the basis of the best signal to noise plus interference ratio, a connection is likely to be transferred to another macrocell rather than to a femtocell. However, in view of the low density of user equipments capable of transceiving with a femtocell, the femtocell could potentially provide a greater data rate to the user equipment terminal than is possible with a macrocell. A cellular wireless network according to an embodiment of the invention employs a method of handover algorithm that has dependence on both a measure of signal quality such as signal to noise plus interference ratio and on a measure of loading of the base station. The handover algorithm is thereby able to weight selection of a base station on the basis of data rate, and intelligently engineer handover to a femtocell.

摘要翻译： 本发明的实施例涉及蜂窝无线网络，并且特别适用于包括不同类型的基站的网络。 所谓的毫微微小区基站通常部署在用户的场所内并以低发射功率工作，提供非常有限的无线覆盖区域。 毫微微小区通常部署在常规宏小区类型的基站的无线覆盖区域内，并且如果基于最佳信噪比加干扰比来执行从宏小区的切换，则可能将连接传送到另一个 宏小区而不是毫微微小区。 然而，鉴于能够使用毫微微小区进行收发的用户设备的密度较低，毫微微小区可能比用宏小区可能向用户设备终端提供更大的数据速率。 根据本发明的实施例的蜂窝无线网络采用切换算法的方法，该方法与信号质量的测量（诸如信噪比加干扰比）和基站的负载量度相关。 因此，切换算法能够基于数据速率加权基站的选择，并且智能地设计到毫微微小区的切换。
