Problems solved by technology

[0009] Existing cross-slot resource usage schemes can not take into account both avoiding strong interference in cross-slots and reducing capacity loss
The method of setting all cells to the same time slot uplink and downlink allocation scheme limits the flexibility of TDD system resource allocation, so that when the business ratio of each cell is inconsistent, the uplink and downlink resource ratio cannot be well matched with the uplink and downlink business ratio. match, leading to a drop in resource utilization

Embodiment Construction

[0050] The core of the present invention is to allocate cross-slot resources to the user according to the set cross-slot usage conditions when the user accesses by setting the use conditions of the cross-slot, and monitor the state of the user, according to the The state adjusts the cross-slot resource allocated to the user, so that the system can make full use of the cross-slot resource, reduce the system capacity loss caused by the asymmetry of uplink and downlink services, and ensure the communication quality of users in the cross-slot.

[0051]In order to enable those skilled in the art to better understand the present invention, a detailed analysis of the interference in the cross-slot in the TD-SCDMA system is firstly made with reference to the accompanying drawings.

[0052] Those skilled in the art know that in a TDD mobile communication system, reception and transmission are performed in different time slots of the same frequency channel (ie carrier), and a guaranteed ...

Abstract

This invention discloses a method and a device for using cross slot resources in the time division duplex CDMA system conditions for using cross slots, assigning cross slot resources for users according to the designed conditions of using cross slots when a user applies for cut-in monitoring the cut-in user status in the cross slot to regulate and maintain the cross slot resources assigned to users. The device for realizing the said method is composed of a designing device, a storage device, a monitor device and a cross-slot distribution device.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and device for using cross-slot resources in a time division duplex code division multiple access system. Background technique [0002] With the rapid development and increasing integration of mobile communications, data communications and the Internet, as well as the growing demands of mobile users for business diversity and the further improvement of service quality requirements, the third generation mobile communication system (3G) standard has been formulated. and put into commercial operation. In the 3G system, in addition to providing traditional voice and multimedia services (symmetrical services), numerous data services (asymmetrical services, such as packet switching and Internet) are also carried. Data services have the characteristics of asymmetric uplink and downlink requirements, and downlinks often need to transmit more traffic. In this cas...
