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.

[0062] 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:

[0063] 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,....

[0104] 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 :

[0105] 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...

[0110] Assume that in the conditional advanced decision, there are 3 decision stages, and the communication parameters obtained in each decision stage are the same, for example, the maximum transmission power ratio value in the uplink communication parameters (assuming that the communication system adopted by the multi-antenna terminal for LTE standard). In addition, the stage thresholds of each decision stage in the conditional advanced decision are equal, for example, the stage thresholds D1=D2=D3=60% of the first decision stage to the third decision stage. See Figure 7 The flowchart of the antenna switching method shown in:

[0111] S702. Obtain the current maximum transmission power ratio value of each antenna of the multi-antenna terminal.

[0112] Assume that after collecting the current maximum transmission power ratio parameters of each antenna, determine the current main antenna, auxiliary antenna and idle antenna, that is, the maximum transmission power ratio valu...

Abstract

The invention discloses an antenna switching method, a multi-antenna terminal and a computer-readable storage medium, wherein the antenna switching method is applied to a multi-antenna terminal including a main receiving and receiving channel, an auxiliary receiving channel and at least three groups of antennas, by obtaining the antennas of each group of antennas For uplink communication parameters, perform conditional advanced judgments in at least two judgment stages on the performance of each group of antennas to determine whether antenna switching is required. Before determining whether to reselect the main and auxiliary antennas, two or more judgment stages with timing will be used to evaluate the current performance of each group of antennas, so compared with the one-time evaluation method, the antenna performance is not only simple experience at least two judgments. More importantly, it can objectively and comprehensively evaluate the overall performance of each group of antennas during the conditional advanced judgment period, and eliminate the influence of accidental factors on antenna performance, making subsequent switching reliable and effective, and ensuring that all groups participating in the work after switching The antenna has really stable good performance.

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...
