摘要： A single-cell wireless communication system is partitioned into n sectors, to which channels are allocated from two groups of non-adjacent channels. If the available channels are consecutively numbered from lowest to highest frequency, or vice versa, the groups are, respectively, the even-numbered channels and the odd-numbered channels. These two groups are each subdivided into n/2 sets, with the first set of each group including the lowest numbered channels of the group, the next set including the next lowest-numbered channels of the group, and so forth. The sets are then allocated to the sectors such that the first set of one of the groups is allocated to a first sector, the next set of the same group is allocated to a contiguous sector and so forth, with the last set of the second group allocated to the nth sector. The dividing points between the sets are selected such that any sector has at most a single channel that may experience adjacent-channel interference from a channel that is allocated from a contiguous sector. Preferably, a channel is selected for assignment to the mobile units such that the selected channel is within a greatest gap between the channels of the same set that are then in use. If the selected channel is the one channel that may experience adjacent-channel interference, another channel may be selected from the set.
摘要翻译：单小区无线通信系统被划分为n个扇区，从两组非相邻信道向其分配信道。如果可用信道从低到高频率连续编号，反之亦然，则组分别是偶数频道和奇数频道。这两个组分别被分成n / 2组，每组的第一组包括该组的最小编号的频道，下一组包括该组的下一个最低编号的频道，等等。然后将这些集合分配给扇区，使得一组中的第一组被分配给第一扇区，同一组的下一组被分配给连续的扇区等等，其中第二组的最后一组分配给第n部门。选择组之间的分割点，使得任何扇区具有至多一个信道，其可以经历来自连续扇区分配的信道的相邻信道干扰。优选地，选择信道以分配给移动单元，使得所选择的信道在同一集合的信道之间的最大间隙内，然后被使用。如果所选择的信道是可能经历相邻信道干扰的一个信道，则可以从该集合中选择另一个信道。

摘要： A frequency allocation plan for a wireless communication system that accommodates growth in demand from a low density reuse pattern of twelve cells to a high efficiency reuse pattern of three cells. The available radio spectrum is first divided into three ranges and each range is further divided into four groups. The frequencies in each range are sequentially assigned to the four groups. The groups are further identified as even and odd groups. The twelve cell groups are laid out in rectangular shapes of four cells wide by three cells high, with a first set of three cells in the upper left portion being assigned to use a first even index frequency group. A second group of three cells in a lower left portion are assigned to use a second even index frequency group. A third and fourth group of cells associated with upper right and lower right positions are assigned the first and second odd index frequency group. As traffic density increases the cells are split into six sectors with each sector being assigned the other odd or even frequency group to achieve a reuse factor of six. Sectorizing to a cell reuse pattern of three is then implemented by swapping the resulting frequency assignments made to a leftmost column of three cells with a non-adjacent center column of a cell group to the left. In order to implement times three reuse in the rightmost column of cells, odd and even frequency assignments are similarly swapped between the leftmost column and the non-adjacent center column of the cell group to the right.
摘要翻译：一种无线通信系统的频率分配方案，其适应从12个小区的低密度重用模式到3个小区的高效率重用模式的需求增长。可用的无线电频谱首先分为三个范围，每个范围进一步分为四组。每个范围中的频率被顺序分配给四组。这些组进一步标识为偶数和奇数组。十二个单元组以四个单元宽三个单元的矩形形状布置，其中左上部分中的第一组三个单元被分配使用第一偶数索引频率组。分配左下部分中的第三组三个单元以使用第二偶数索引频率组。与右上右右位置相关联的第三组和第四组单元被分配第一和第二奇数索引频率组。随着业务密度增加，小区被分成六个扇区，每个扇区被分配另一个奇数或偶数频率组，以实现重用系数为6。然后通过将对三个单元的最左列的所得到的频率分配与左侧的单元组的非相邻中心列进行交换来实现对三个单元重用模式的分级。为了在单元格的最右边的列中实现三次重用，奇数和偶数频率分配在右侧的单元组的最左列和非相邻中心列之间类似地交换。

摘要： A radio frequency control technique for use in a wideband communications system, such as a Code Division Multiple Access (CDMA) system in which the use of several wideband forward channels is allocated in each cell, depending upon the apparent location of the mobile station in the cell. In particular, a first set of channels is reserved for the mobiles within a first certain radius of the base station antenna, and a second set of channels serve the area forming mobiles located in a concentric annular ring centered around the base station antenna. Third, fourth, and subsequent concentric rings may be used to provide successively longer radii from the base station to support the use of additional frequency sets in each cell.

摘要： A system for determining the location of a mobile station (MS) based upon measurable mobile data values such as those provided by mobile-assisted handoff (MAHO) procedures. The mobile stations make signal strength measurements of nearby base stations (BS) and return that information to the serving base station. A timing advance necessary to synchronize the mobile may also be determined. The signal strength measurements and the timing advance data then provide information to map to an estimated vehicle location. Since the mobiles are assumed to measure signal strength discretely, there may be several consecutive positions along a road (22) which return identical mobile data. The road is thus segmented into constant segments which are consecutively indexed, and an association is established between the associated mobile data vector and the index. The process for location of a mobile consists of first finding the road for the mobile unit, then finding the position along the road. The mobile vector is sequentially input into a look up table or neural networks (one for each road in the sector) until an output coordinate pair actually lies near the corresponding road. From that point on, the input vector provides an index to a constant region along the road, so the mobile is unambiguously located as to which road, and to which segment along the road it occupies.
摘要翻译：一种用于基于可移动的移动数据值（例如由移动辅助切换（MAHO）过程提供的那些）来确定移动站（MS）的位置的系统。移动台进行附近基站（BS）的信号强度测量，并将该信息返回给服务基站。也可以确定同步移动站所需的定时提前。信号强度测量和定时提前数据然后提供信息以映射到估计的车辆位置。由于假设移动台离散地测量信号强度，所以沿道路（22）可能有几个连续的位置返回相同的移动数据。因此，道路被分段成连续索引的常数段，并且在相关联的移动数据向量和索引之间建立关联。移动的位置的过程包括首先找到移动单元的道路，然后找到沿着道路的位置。将移动向量顺序地输入到查询表或神经网络（一个用于扇区中的每个道路），直到输出坐标对实际位于相应的道路附近。从那时起，输入向量向沿着道路的恒定区域提供索引，因此移动站明确地定位到哪个道路，以及沿其所占据的道路的哪个段。

摘要： A technique for allocating frequencies in a cellular communication system. The frequency reuse plan divides all available frequencies into six groups with the frequencies assigned in an ascending index order modulo 6. A three cell reuse plan is implemented with six 60° sectorized antennas per cell, and two frequency groups being assigned for use in each cell. The channel groups are allocated to the sectors such that no two adjacent sectors use the same frequency groups. As a result, an effective times one frequency reuse plan is implemented. A frequency assignment process which attempts to avoid assigning the same frequency to amobile which is located in the outer portion of a sector which is also in use in potential interfering outer sectors of homologous cells insures that carrier to interference (C/I) ratio minimums can be met without specialized encoding techniques.
