Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide an antenna switching scheme, which is used to change the working roles of each antenna in the terminal when the working environment of the terminal antenna is unstable, so as to solve the problem of fixed antenna working roles in the existing solution. Therefore, when the main antenna is blocked, it is easy to cause a sharp drop in the transceiver performance of the mobile terminal and poor user experience.

[0061] In order to solve the problem in the prior art that the working role of the antenna in the terminal is fixed, so that the receiving and transmitting performance of the terminal is easily affected by factors such as the user's holding posture, thus making the communication performance of the terminal unstable, this embodiment will provide an antenna switching method. This antenna switching method is mainly applied to multi-antenna terminals including multiple antennas. In order to facilitate the understanding of the application scenarios of the antenna switching method, the following first combines figure 2 The hardware structure of the radio frequency unit of the multi-antenna terminal in this embodiment is introduced:

[0062] The terminal in this embodiment includes at least three sets of antennas 211, 212...21m, an antenna gating circuit 22, a radio frequency circuit 23 and a baseband processor 24, and the antenna gating circuit 22 has n first interfaces 2211, 2212,....

[0116] This embodiment first introduces the setting positions of multiple groups of antennas of the multi-antenna terminal in the foregoing embodiments, please refer to Figure 5 :

[0117] exist Figure 5 Among them, exactly three groups of antennas are arranged in the multi-antenna terminal 50, wherein the first antenna group 51 is arranged on the top, and the second antenna group 52 and the third antenna group 53 are respectively arranged on the left and right sides of the bottom of the terminal. Since the roles of "main antenna", "secondary antenna" and "idle antenna" in this embodiment are interchangeable, for a multi-antenna terminal 50, at a certain moment, the first antenna group 51 may be used as the main antenna, The second antenna group 52 works as a secondary antenna, and the third antenna group 53 does not work temporarily. At another moment, the second antenna group 52 and the third antenna group 53 may be used as the main antenna and the auxiliary antenna to p...

[0122] Assume that the conditional advanced judgment includes three judgment stages, and the communication parameters obtained in each judgment stage are all downlink communication parameters, and the downlink communication parameters obtained in the three judgment stages are not the same, for example, the first judgment stage The downlink communication parameter obtained is received signal strength, the downlink communication parameter obtained in the second judgment stage is signal quality, and the third judgment stage is bit error rate. When obtaining the dimensionless pairwise differences, the normalized dedimensionalization method is adopted, so the stage thresholds set for the three judgment stages are 35%, 28% and 20%, respectively. Now take the first judgment stage as an example to introduce the conditional advanced judgment, please refer to Figure 7 The flowchart of the antenna switching method shown in:

Abstract

The invention discloses an antenna switching method, a multi-antenna terminal, and a computer-readable storage medium. The antenna switching method is applied to the multi-antenna terminal including aprimary transceiver path, a secondary receiver path and at least three groups of antennas. Whether antenna switching is required is determined by acquiring the communication parameters of respectivegroups of antennas and subjecting the performance each group of antennas to condition advanced decision with at least two decision stages. Since two or more decision phases with a timing sequence areused to evaluate the current performance of each group of antennas before it is determined whether the primary antenna or the secondary antenna is required to be reselected, the overall performance ofeach group of antennas can be objectively and comprehensively evaluated during the condition advanced decision and an influence of accidental factors on the antenna performance can be removed. Moreover, since the communication parameters are different in the at least two decision phases, the performance of the antennas in at least two communication parameter dimensions can be evaluated, thereby achieving a comprehensive antenna performance evaluation result and reliable and effective subsequent switching.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to an antenna switching method, a multi-antenna terminal, and a computer-readable storage medium. Background technique [0002] With the development of terminal technology, the functions of mobile terminals are becoming more and more comprehensive, and the services it provides to users are becoming more and more perfect. At its simplest, mobile terminals have derived services in many aspects, such as taking pictures, surfing the Internet, and playing audio / video, from the pure call and text message functions in the past. However, although mobile terminals currently have a wide variety of functions, and with the development of technology, there will still be more and more intelligent functions that will spring up like mushrooms in future terminals, but the communication functions carried by mobile terminals will still be used as One of the most basic and impo...
