Embodiment Construction

[0036] According to the embodiment of the present invention, the network side device determines whether the first cell can autonomously perform uplink and downlink configuration according to the first RSRP (Reference signal received power, reference signal received power) value of the reference signal received by the first cell from the adjacent second cell; or The base station determines whether the current cell can autonomously perform uplink and downlink configuration according to the first RSRP value received by the current cell from the reference signal of the neighboring cell. By detecting the RSRP value, it is determined whether the cell can perform uplink and downlink configuration independently, so that the dynamic uplink and downlink configuration can run normally, and in the dynamic uplink and downlink configuration environment, the interference between neighboring cells can be reduced and the system efficiency can be improved.

Abstract

The embodiment of the invention relates to the technical field of wireless communication, in particular to a method, a system and equipment for determining uplink and downlink configuration, which are used for detecting interference so as to determine whether a cell can independently perform uplink and downlink configuration or not. The method of the embodiment of the invention comprises that: network side equipment determines a first reference signal receiving power (RSRP) value of a first cell receiving a reference signal from a second cell which is a neighboring cell of the first cell; and the network side equipment determines whether the first cell can autonomously perform the uplink and downlink configuration or not according to the first RSRP value. In the method, the system and the equipment, the RSRP value is detected to judge whether the cell can independently perform the uplink and downlink configuration or not to normally operate the dynamic uplink and downlink configuration, interference among the neighboring cells can be reduced in a dynamic uplink and downlink configuration environment, and the efficiency of the system is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, system and equipment for determining uplink and downlink configurations. Background technique [0002] For the basic duplex mode adopted by the cellular system, the TDD (Time division duplex) mode means that the uplink and downlink use the same working frequency band, and the uplink and downlink signals are transmitted at different time intervals. There is a guard interval (Guard Period, GP) between them; FDD (Frequency division duplex, frequency division duplex) mode means that the uplink and downlink use different working frequency bands, and the uplink and downlink signals can be carried out on different frequency carriers at the same time There is a guard bandwidth (Guard Band, GB) between the uplink and downlink. [0003] The frame structure of the LTE (Long Term Evolution, long-term evolution) TDD system is slightly more complicated, such a...
