摘要： In controlling a multi-beam antenna system for downlink wireless communication, beamforming and closed loop transmit diversity signaling are combined. Each beam signal is adjusted at the transmitter based on feedback from a wireless mobile communication station such that the signals received at the wireless mobile communication station can be coherently combined.

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： The beam pattern associated with a multi-beam antenna array is adjusted if a first beam of the beam pattern is overloaded. A lobe of a second beam of the beam pattern can be steered away from a main lobe of the first beam. Also, if a user is located in an area covered by a second beam which is adjacent to the first beam, a third beam of the beam pattern can be selected for effectuating communication with the user. If a user is located in an area covered by the first beam, another beam of the beam pattern can be selected for effectuating communication with the user.

摘要： A composite signal including a plurality of component signal streams is processed using QR-decomposition to detect symbols and calculate a decision metric for each of the signal streams (202). Soft serial interference cancellation is performed on the composite signal based on the symbols detected for different ones of the signal streams and a ranking of the signal streams (204). The symbols are re-detected and the decision metric re-calculated for each signal stream based on soft serial interference cancellation results (206). The different decision metric calculations for at least one of the signal streams are compared to determine whether symbol detection is more accurate with or without soft serial interference cancellation (208). The signal streams are decoded using symbols detected based on soft serial interference cancellation results when symbol detection is determined to be more accurate with soft serial interference cancellation (210). Otherwise, the streams are decoded based on the symbols detected using QR-decomposition (210).

摘要： The present invention relates to a system and a method for transmitting data between a first terminal and a communication network access point. The method may comprise the steps of defining a first set of scrambling codes and a second set of scrambling codes different from the first set of scrambling codes. Further, the method may comprise defining a first selection scheme for a first parameter. The method may still further comprise determining a current parameter value for the first parameter and evaluating the current parameter value on the basis of the first selection scheme and selecting a scrambling code from the first set of scrambling codes or the second set of scrambling codes based on the evaluation. Even further, the method may comprise packaging and transmitting data between the first terminal and the communication network access point using the selected scrambling codes.

摘要： The present invention relates to a method and arrangements in a communication system for Multi User Multiple-Input-Multiple-Output (MU-MIMO) signaling via Multiple-Input-Multiple-Output (MIMO) antennas between a base station and one of a plurality of mobile terminals supporting both Single User and Multi User Multiple-Input-Multiple-Output (SU-MIMO and MU-MIMO) signaling modes. Switching between the modes is supported in the system and the modes have partly shared signaling. SU-MIMO mode signaling which is redundant, i.e. not needed, for MU-MIMO mode signaling is identified. Bits, i.e. data bits, of the identified redundant signaling is re-interpreted or re-defined to comprise signaling information associated with MU-MIMO mode. The signaling information associated with MU-MIMO mode is signaled to the mobile terminal by using the reinterpreted redundant bits.
