摘要： The invention provides an increase in the radio coverage area (10) of a base transceiver station (100) having access to multiple transceivers (102, 104, 106, 108) by dedicating at least one of the transceivers (102) for BCCH data. This BCCH transceiver (102) is connected to an antenna arrangement (120) 5 comprising at least two antenna elements (121, 123; 125, 127). Increased BCCH radio coverage (30) is achieved by providing antenna hopping among the at least two antenna elements (121, 123; 125, 127) for the BCCH. Correspondingly, increased TCH coverage (20) is achieved by providing frequency hopping among at least two carrier frequencies for the TCH. The 10 coverage (10) of the base transceiver station (100) is defined as the intersection of the BCCH radio coverage (30) and the TCH coverage (20).

摘要： Handover is a main function that is used to support mobility in the network. In a cellular communication network having adaptive antennas for enabling narrow beam operation, it is assumed that a mobile unit is served by an active cell set (S1). A basic idea according to the present invention is to select, prior to establishment of a new serving radio link for a mobile unit, a narrow target beam within a neighbor area of the current active cell set of the mobile unit based on pre-established information of narrow beams within the neighbor area (S2), and to initiate establishment of the new serving radio link directly with the selected narrow target beam (S3). In this way, the narrow target beam can be selected at handover initiation and the new radio link can be established directly with a target narrow beam without first establishing the radio link with a cell-wide beam and then, after uplink measurements, reconfiguring the radio link onto a narrow beam.

The first unit comprises means for managing information of at least one additional identity of a mobile terminal or a channel, belonging to at least a second base station, it should be aware of for interference mitigation purposes, preferably means for detecting whether the mobile terminal or channel identified by said additional identity is active and means for mitigating cell-interference caused by an active mobile terminal or a channel identified by the additional identity.

摘要： Handover is a main function that is used to support mobility in the network. In a cellular communication network having adaptive antennas for enabling narrow beam operation, a network control unit sends a radio link setup request to a selected cell-serving network unit for configuration of a new serving radio link. Before responding to the radio link setup request the cell-serving network unit performs uplink measurements with respect to the mobile unit, and a narrow target beam is selected within a cell served by the cell-serving network unit based on these measurements. The cell-serving network unit then configures the new serving radio link for the considered mobile unit directly with the selected narrow target beam. Consequently the system can perform the handover procedure using narrow beams only, without first establishing the radio link with a cell-wide beam and then reconfiguring the radio link onto a narrow beam.
摘要翻译：移交是用于支持网络中移动性的主要功能。在具有用于实现窄波束操作的自适应天线的蜂窝通信网络中，网络控制单元向所选择的小区服务网络单元发送无线链路建立请求，以配置新的服务无线电链路。在响应无线电链路建立请求之前，小区服务网络单元针对移动单元执行上行链路测量，并且基于这些测量，在由小区服务网络单元服务的小区内选择窄目标波束。小区服务网络单元然后使用所选择的窄目标波束来直接配置所考虑的移动单元的新的服务无线电链路。因此，系统只能使用窄波束执行切换过程，而无需首先用小区宽波束建立无线电链路，然后将无线电链路重新配置到窄波束上。

摘要： Random access coverage is assured while at the same supporting high uplink data rates in a same service area served by a base station. The service area includes first and second co-sited cells. The first co-sited cell is associated with a first uplink frequency, and the second co-sited cell is associated with a second uplink frequency. The first cell allows a lower uplink load and provides a greater coverage than the second cell. The second cell allows a higher rise over thermal (RoT) value than the first cell. Random access channel requests are initially directed to the first cell using the first uplink frequency. One of the co-sited cells is selected for supporting the connection depending on one or more factors. Example factors include a priority associated with the mobile terminal, a capability associated with the mobile terminal, a load situation in the second cell, or radio channel conditions associated with the mobile radio terminal.
