    • The invention relates to a method for estimating time of arrival of radio signals in particular as used for location determination. A known method of determining the location of a subscriber unit (401) calculates a number of ranges based on the distance from base stations (403,405,407) with known location. The ranges are calculated from time of arrival estimates of the signals from the different base stations but a significant source of error is the multipath signal components typical in for example cellular mobile communication systems. According to the invention, the effect of multipath is mitigated by selecting a subset of signals based on a time of arrival estimate of each of the signals. An averaged time of arrival estimate with improved accuracy is then determined from the selected subset. A typical use of the invention is for location determination in a cellular mobile communication system.
    • 本发明涉及一种用于估计无线电信号的到达时间的方法,特别是用于位置确定。 确定用户单元(401)的位置的已知方法基于与具有已知位置的基站(403,405,407)的距离来计算范围的数量。 范围是根据来自不同基站的信号的到达时间估计计算的,但是重要的误差源是例如蜂窝移动通信系统中典型的多径信号分量。 根据本发明,通过基于每个信号的到达时间估计选择信号子集来减轻多路径的影响。 然后从所选择的子集确定具有改进的准确度的平均到达时间估计。 本发明的典型用途是用于蜂窝移动通信系统中的位置确定。

    • This invention relates to an antenna array system. A problem with antenna array systems is that they provide rather inefficient use of hardware and have inflexible resource allocation. The invention provides a flexible antenna array system architecture, which has very flexible allocation of transceiver elements to beams. The invention comprise switching means (407) which associate transceiver elements (405) to beam ports of a beam former (403) connected to a antenna array (401). The association of transceiver elements (405) to beam ports are rearranged regularly, typically for each time slot, and the association is optimized for overall performance for all subscriber units. The invention is applicable for example to cellular communication systems such as GSM.

    • This invention relates to a packet scheduler and method therefor and in particular a scheduler for a Code Division Multiple Access cellular mobile communication system. In packet base systems it is important to schedule transmissions of packets carefully in order to maximize the capacity of the system. The scheduler has a selection unit (233) for selecting a candidate set of packets. The candidate set is fed to a processor (235) for calculating transmit powers required by remote terminals to transmit the packets based on the candidate set. The calculated transmit powers are fed to a controller (237) for modifying the candidate set in response to the calculated transmit powers and the modified set is fed to a scheduler unit (239) for scheduling the packets of the candidate set for transmission. The scheduler is in particular appropriate for third generation mobile communication systems.

    • This invention relates to a method of estimating a characteristic of a signal such as a time of arrival or a transmitter identity in particular in a cellular communication system. Most known techniques have limited performance as they rely on limited amounts of known data. The method of the invention comprise a first step (201) of receiving the signal at a subscriber unit. In a second step (203) the subscriber unit receives assistance data from the fixed network and in a third step (205) an expected signal is derived in response to this assistance data. For GSM the assistance data can be a frame number and a BSIC permitting an entire expected SCH burst to be derived. In a fourth (207) step the signal characteristic is determined by correlation of the received signal and the expected signal. The invention is particularly applicable to location determination in a GSM communication system.
    • 本发明涉及一种特别是在蜂窝通信系统中估计诸如到达时间或发射机身份的信号的特性的方法。 大多数已知技术的性能有限,因为它们依赖于有限数量的已知数据。 本发明的方法包括在用户单元处接收信号的第一步骤(201)。 在第二步骤(203)中,用户单元从固定网络接收辅助数据,并且在第三步骤(205)中,响应于该辅助数据导出预期信号。 对于GSM,辅助数据可以是帧号,BSIC允许导出整个预期的SCH突发。 在第四(207)步骤中,通过接收信号和预期信号的相关来确定信号特性。 本发明特别适用于GSM通信系统中的位置确定。
