Embodiment Construction

[0023] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only the technical solutions of the present invention. Some, but not all, embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0024] like figure 1 As shown, the present invention provides a mode switching method. The handover method is mainly used in base stations. Wherein, the base station communicates with multiple mobile terminals at the same time, and adopts a spatial multiplexing method when transmitting data with each mobile terminal. Each channel is multiplexed...

Abstract

The invention provides a mode switching method, a system and a base station applying the same. According to the method, the base station is based on the acquisition of CSI information of various layers of signals received in a first mode by a mobile terminal to calculate the first signal-to-noise ratio of the mobile terminal corresponding to the various layers of signals in the first mode; according to the first signal-to-noise ratio and the CSI information, the CQI information of the corresponding layers of signals received by the mobile terminal in a second mode is estimated; according to the CSI information and the corresponding CQI information in the second mode, the transmission speeds of various layers of signals are determined; and according to the comparison result of the transmission speed of the same layer of signal in the first mode and the second mode, a first mode or a second mode for data transmission of the corresponding layer is selected. The invention is able to avoid the data exchange of mobile terminals during the switching period, and effectively reduces the occupation rate of channels.

Description

technical field [0001] The present invention relates to the communication field, in particular to a mode switching method, system and applicable base station. Background technique [0002] The dynamic switching of SUMIMO (Single User Multi Input and Multi Output) and MUMIMO (MultiUser Multi Input and Multi Output) is supported in the current popular LTE system, which can bring higher system efficiency and more flexible resource scheduling . At the same time, it also brings the challenge of resource scheduling, so that the base station can judge the resource scheduling strategy more accurately according to the information reported by the mobile terminal. [0003] Although the LTE system supports dynamic switching between SUMIMO and MUMIMO, it is imperceptible to the mobile terminal, that is, the mobile terminal does not know whether it is in the SUMIMO or MUMIMO state. Therefore, all the information of the mobile terminal is reported based on the SUMIMO situation. When the...
