Problems solved by technology

The main disadvantages of this prior art are: firstly, the terminal can only measure the time slot interference for the same frequency, but cannot measure the time slot interference between frequencies; slot interference
It can be seen that using the prior art method of using the terminal to measure the time slot interference, it is impossible to allocate suitable channel resources for the terminal, so that the mutual interference between the terminals is relatively large

Embodiment Construction

[0034] In the present invention, in the wireless communication system, after the terminal is initially connected, the NodeB can measure the angle information and the distance information of the terminal through the smart antenna, and the RNC allocates suitable channel resources for the terminal according to the position of the terminal.

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] In the following embodiments of the present invention, the TD-SCDMA system will be used as an example to describe, but the method provided by the present invention is not limited to the application in the TD-SCDMA system, and can also be applied to other wireless communication systems, such as broadband Code Division Multiple Access (WCDMA) system.

[0037] In order to realize the purpose of the present invention, in the R...

Abstract

The invention provides a channel resource distributing method in the wireless communication system when the terminal originally switches in, which can distribute suitable channel resource for the terminal, and thus decreasing the mutual disturbance among terminals. According to the method that is provided by the invention, when RNC decides that the terminal switches from non-private channel condition to private condition, Node B can test and get effective direction of arrival information and synchronal timing advanced quantity information, and send the information to RNC through the RACH frame. RNC can confirm the position of the terminal according to the effective direction of arrival information and synchronal timing advanced quantity information, and also collocate suitable channel resource for the terminal at the angle through the terminal to the base station. In this way, the effect of original distribution of private channel resource is effectively improved, and the mutual disturbance between the user in the subdistrict and the subdistrict is decreased.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method for allocating channel resources when a terminal initially accesses. Background technique [0002] In a wireless communication system, as the user terminal moves, the strength of the communication signal and the signal interference received will also change accordingly. The base station can allocate relevant resources for the user terminal according to the known network information to reduce signal interference. , Improve communication quality. [0003] In a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, downlink beamforming is performed through smart antennas, which can greatly reduce downlink interference between users. At the same time, the base station (Node B) receives the uplink signal sent by the terminal. , and the angle of arrival of the signal can also be calculated. [0004] In the TD-SCDMA system, the air interface is ...
