Technical field
The application relates to wireless communication technology field, particularly relates to a kind of base station and terminal antenna polarised direction collocation method.
Background technology
Along with the development of wireless communication technology, its application is not only confined to the civil areas such as voice communication, is also used widely at industrial circle (such as power information collection and transmission).Relative to common mobile communication system, be exactly that the position of information acquisition terminal is relatively fixing in the notable feature of wireless communication system of industrial circle application, under namely terminal is fixedly in the covering of certain community, seldom occur that user switches.
In order to improve the performance of Cell Edge User better, the especially communication quality of co-frequency cell edge customer, needs the Signal to Interference plus Noise Ratio (SINR) promoting this user in essence.At present for system of broadband wireless communication, normal employing soft-frequency reuse technology promotes user SINR, and this technology, by judging the subdistrict position residing for user, is dispatched targetedly to frequency domain resource, realize channeling, thus effectively promote the SINR of edge customer.
Figure 1 shows that the cell frequency resources configuration schematic diagram of application soft-frequency reuse technology, wherein each hexagon represents a community, and Cell Center User can freely use all frequency resources, and Cell Edge User can only use component frequency resource.Based on soft-frequency reuse technology, the edge of neighbor cell uses different frequencies respectively, thus avoids the adjacent cell co-channel interference of edge customer.
Theory analysis is known, and soft-frequency reuse technology effectively to Cochannel interference, can promote the SINR of Cell Edge User, but the prerequisite that this conclusion is set up accurately to judge the position residing for user.This algorithm needs to carry out correlation computations in terminal, and needs by signaled base station end, and base station end carries out judgement process to the signaling that reports of all users again.
Because soft-frequency reuse technology is mainly based on channel estimating, thus can channel estimation errors be brought, and need to carry out the algorithm process of being correlated with in terminal and base station, add the complexity that equipment realizes.
Summary of the invention
This application provides a kind of antenna for base station collocation method, from the isolation spatially realizing neighbor cell signal, thus effectively promote the SINR of edge customer.

Embodiment
For making the know-why of technical scheme, feature and technique effect clearly, below in conjunction with specific embodiment, technical scheme is described in detail.
Figure 2 shows that the neighbor cell base station polarization mode configuration schematic diagram of application technical scheme.First community and the second community are neighbor cell, and the scope of ellipse representation is the overlay area of cell base station, UE1 and UE2 is positioned at the common overlay area in the first community and the second community.The polarised direction of the first cell-site antenna is vertical direction, and the polarised direction of the second cell-site antenna is horizontal direction, and therefore the antenna polarization direction of the first cell base station and the second cell base station is mutually orthogonal.UE1 is the edge customer of the first community, and its antenna polarization direction is configured to vertical direction, identical with the polarised direction of the first cell-site antenna; UE2 is the edge customer of the second community, and its antenna polarization direction is configured to horizontal direction, identical with the polarised direction of the second cell-site antenna.Like this, spatially realize the isolation of neighbor cell signal, increase the Signal segregation degree being in Cell Edge User, thus effectively promote the SINR of edge customer.
A kind of antenna for base station collocation method that the embodiment of the present application provides as shown in Figure 3, comprises the steps:
Step 301: the installation site determining network's coverage area and base station according to demand.
This step belongs to the network planning, and be very ripe prior art, current beehive network system all can do corresponding simulant design at network planning phase.Detailed process according to the region of the network coverage, can emulate in conjunction with path loss model, thus determines the number that needs in this region to build a station further, and the approximate location residing for site.
Step 302: the overlay area determining each base station according to path loss model, especially determines the fringe region that adjacent co-frequency cell is common.
Step 303: the position residing for user, determines the user being arranged in the common fringe region in adjacent co-frequency cell, using described user as targeted customer.
Step 304: be configured to mutually orthogonal by the polarised direction of adjacent co-frequency cell antenna for base station, by identical for the antenna polarization direction that the antenna polarization direction of targeted customer is configured to its place cell base station.
Preferably, can carry out network plan simulation further under above-mentioned configuring condition, whether the SINR analyzing edge customer meets system requirements; If individual terminal SINR does not satisfy the demands, its Research of Antenna Polarization is converted, and then emulates, until meet system requirements.
The application's scheme is applied to the SINR that also significantly can promote edge customer in the community of identical networking.Preferably, the mode that soft-frequency reuse and this programme can be combined, is divided into center bin F1 and edge frequency range F2 by whole band frequency, and the polarization isolation that wherein F2 section can utilize this programme to propose carries out the lifting of SINR.
The foregoing is only the preferred embodiment of the application; not in order to limit the protection range of the application; within all spirit in technical scheme and principle, any amendment made, equivalent replacements, improvement etc., all should be included within scope that the application protects.
