Embodiment 1

[0049] In this embodiment, the folding screen terminal has N antennas, wherein, when the folding screen terminal is in a bent state, the M antennas are not blocked and / or interfered, and the (N-M) antennas are blocked and / or interfered .

[0050] Wherein, N and M are both integers, and N≥2, N≥M≥1.

[0051] Figure 5 It is a schematic flowchart of an antenna control method according to Embodiment 1 of the present invention, and the method includes the following steps:

[0052] S501: Detect the state of the folding screen terminal, if the folding screen terminal is in the bent state, execute step S502, and if the folding screen terminal is in the unfolded state, execute step S505.

[0053] The folding screen terminal in this embodiment includes a first screen and a second screen, and a first sensor located below the first screen and a second sensor located below the second screen;

[0054] Detecting the state of the folding screen terminal specifically includes: detecting the...

Embodiment 2

[0073] In this embodiment, the folding screen terminal has four antennas, which are ANT0-ANT3 respectively. The architecture block diagram of the folding screen terminal is as follows: Image 6 As shown, its main functional modules include:

[0074] The baseband processor is mainly responsible for processing communication data, and controlling the working status of devices in the radio frequency path according to the interactive information between the folding screen terminal and the network, such as the judgment of the SRS rotation mechanism in this embodiment, and the detection of the folding state of the folding screen terminal etc.; as mentioned earlier, the first sensor and the second sensor are respectively located under the first screen and the second screen, and the data detected by the first sensor and the second sensor about the first screen and the second screen will be sent back to the baseband for processing processor to obtain the folding state of the folding scr...

Abstract

The invention discloses an antenna control method, which is applied to a folding screen terminal, and comprises the following steps: if the folding screen terminal is in a bending state, carrying outSRS (Sounding Reference Signal) in-turn transmission through first target antennas, wherein the number of the first target antennas is smaller than the number of all antennas of the folding screen terminal. The invention further discloses a corresponding folding screen terminal, a mobile terminal and a computer readable storage medium. By applying the technical scheme disclosed by the invention, the SRS in-turn transmission efficiency of the folding screen terminal can be improved, and meanwhile, the power consumption of the terminal can be saved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to an antenna control method and a mobile terminal. Background technique [0002] With the continuous advancement of science and technology, the folding screen terminal that only stayed in the concept map has become a reality. First-line manufacturers at home and abroad continue to release their folding terminal products, and support 5G communication. [0003] In the 5G communication system, in order to improve the downlink transmission capability, the terminal needs to perform NR SRS (New RadioSounding Reference Signal: new wireless communication channel sounding reference signal) rounds, so that the network side can estimate the uplink channel, and select MCS (Modulation and Coding Scheme: Modulation and coding strategy) and uplink frequency selective scheduling. In a TDD system, the uplink channel matrix H also needs to be estimated for downlink beamforming....
