Abstract

The invention provides a method for changing up and down TDD (Time Division Duplexing) configuration. The method comprises the steps that user equipment measures interference of user equipment in an adjacent cell to the user equipment and reports the interference situation to a base station, and the base station changes the current up and down TDD configuration according to the interference situation reported by the user equipment and the current up and down service requirements. The method meets the requirement of the dynamically changing up and down service load under the condition that the serious interference between the adjacent cells is not caused.

Description

technical field

[0001] The invention relates to wireless communication technology, in particular to a method for changing TDD uplink and downlink configurations. Background technique

[0002] The Long Term Evolution (LTE) system supports two duplex modes of Frequency Division Duplex (FDD) and Time Division Duplex (TDD). figure 1 It is the frame structure of the TDD system. The length of each radio frame is 10ms, which is equally divided into two half-frames with a length of 5ms. Each half-frame contains 8 time slots with a length of 0.5ms and 3 special domains, namely downlink pilot time slot (DwPTS), guard interval (GP) and uplink pilot time slot (UpPTS), these 3 special domains The sum of the lengths is 1ms. Each subframe consists of two consecutive time slots, that is, the kth subframe includes time slot 2k and time slot 2k+1. The TDD system supports seven uplink and downlink configurations, as shown in Table 1. In Table 1, D represents a downlink subframe, U represe...
