Double-period dynamic configuration method for ratio between TDD (Time Division Duplex) uplink subframes and TDD downlink subframes, base station, system and communication equipment

Abstract

The invention provides a double-period dynamic configuration method for ratio between TDD (Time Division Duplex) uplink subframes and TDD downlink subframes, which is used for configuring a ratio between the time division duplex uplink subframes and the time division duplex downlink subframes of first communication equipment which supports an eIMTA function and second communication equipment which does not support the eIMTA function. The dynamic configuration method comprises the following steps of: determining a first configuration parameter for the ratio between the time division duplex uplink subframes and the time division duplex downlink subframes, which is to be applied to the first communication equipment; determining a corresponding second configuration parameter according to one or more history first configuration parameter used by the first communication equipment; and applying the first configuration parameter to the first communication equipment within a first reconfiguration period and applying the second configuration parameter to the second communication equipment within a second reconfiguration period. The invention further discloses a corresponding base station, a corresponding system and corresponding communication equipment. Through the adoption of a technical scheme of the invention, the different configuration parameters can be adopted for different communication equipments during hybrid networking of the communication equipments with different versions, so that performance degradation of partial communication equipments due to the use of single parameter is avoided.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular, to a dual-period dynamic configuration method, a base station, a system and a communication device for TDD uplink and downlink subframe ratios. Background technique [0002] In recent years, the new-generation wireless communication technology has developed rapidly. Compared with the third-generation wireless communication technology, the new-generation mobile communication technology has many advantages such as simple network architecture, small signal delay, high communication quality, and fast speed. According to the multiplexing mode of uplink and downlink services, the new generation mobile communication technology can be divided into TDD (Time Division Duplex, time division duplex) system and FDD (Frequency Division Duplex, frequency division multiplexing) system. Compared with the FDD system, the TDD system has a higher utilization efficiency of system resource...

Problems solved by technology

As a result, the performance of the old-version UE and the new-version UE cannot be balanced, and the overall performance gain of the system cannot be fully reflected by dynamic configuration.

[0010] Therefore, a new technical solution is needed. When different versions of communication devices are mixed in a network, different configuration parameters can be used for different communication devices, so as to avoid performance degradation of some communication devices when a single parameter is used.
