Embodiment Construction

[0043] The core of the present invention is to pre-set the adjacent base stations that need to be detected in this cell and the corresponding pilot signal strength threshold value, and compare the adjacent cell pilot signal strength received by the terminal with the set threshold value, Determine whether the UE enters the cross-slot forbidden area according to the comparison result, and restrict the terminals in the forbidden area in the local cell to use the uplink cross-slot resources of the base station of the local cell and the base stations of these adjacent cells. When assigning time slots, the RNC first checks whether there are users in the cross-slots of adjacent cells. When there are no users in these adjacent cells, the terminal in this cell can be allowed to use uplink cross-slot resources, otherwise it is forbidden The terminal in the cell uses the uplink cross-slot resource.

Abstract

This invention discloses one codes division double work system crossing time gap matching method, which comprises the following steps: presetting local area needed station and its relative conductive signal intensity gate values to get the needed conductive frequency signals; determining whether the terminal is at depression crossing time gap interference area according to the needed adjacent station conductive signals and preset signal preset gate values; limiting local area needed depression time gap terminal to use station and adjacent station to form upper crossing time gap materials.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for allocating cross time slot resources in a code division multiple access / time division duplex system. Background technique [0002] In the third-generation mobile communication system, a large number of services are distributed in the downlink direction, thus forming an asymmetry of uplink and downlink traffic. In order to use wireless resources more effectively, resource allocation must satisfy this asymmetry of the rate. The TDD (Time Division Duplex) system can dynamically allocate radio resources for uplink and downlink, so as to better meet this requirement. In the standard of the third generation mobile communication system adopted by ITU (International Telecommunication Union), TD-SCDMA (Time Slot-Synchronous Code Division Multiple Access) system and UTRA-TDD (Universal Terrestrial Radio Access-Time Division Duplex) system are both It is a CDMA / T...
