Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to an antenna control method and a terminal.

Background

With the rapid development of electronic technology, terminals such as smart phones and tablet computers have become more and more popular and become indispensable tools for people's daily life. People have higher requirements on the terminal during the use of the terminal, especially on the communication quality of the terminal. For this reason, the multiple antenna technology is applied to a terminal, for example, as shown in fig. 1, the terminal is provided with four antennas (i.e., ANT0, ANT1, ANT2, ANT3), i.e., one or two antennas are in a main operation state as a main antenna to receive and transmit signals, and the other antennas are in a sub operation state as a sub antenna to further assist in receiving signals.

However, in some scenarios, the communication capability of the antenna for transmitting the uplink data may be reduced, for example, as shown in fig. 2, when the user holds the terminal, the antenna ANT2 and the antenna ANT3 of the terminal are shielded, which may reduce the signal transceiving capability of the shielded antenna, especially in the case that the terminal runs an application program and transmits the uplink data through the antenna for transmitting the signal, when the main antenna is shielded, the rate of the terminal for transmitting the uplink data may be directly reduced, thereby causing the application program to be jammed.

It can be seen that, when the terminal transmits the uplink data of the application program at present, the problem that the operation of the application program is stuck exists.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, it is a schematic flowchart of an antenna control method according to an embodiment of the present invention, which is ultimately applied to a terminal with N antennas, and as shown in fig. 1, the antenna control method includes the following steps:

step 301, monitoring a Buffer Status Report (BSR) of the terminal;

step 302, controlling M antennas of the N antennas to be in an active state based on the BSR, where M is a positive integer and is less than or equal to N;

step 303, switching the transmitting antenna of the terminal to a target antenna among the M antennas, where the communication quality of the target antenna is higher than the communication quality of the transmitting antenna before the terminal is switched.

Here, the terminal may control M antennas of the N antennas to be in an activated state according to the BSR, and switch the current transmitting antenna to the target antenna, so that in a scenario where the communication quality of the transmitting antenna is degraded, such as when the transmitting antenna is blocked, the current transmitting antenna may be switched to the target antenna with higher communication quality to transmit uplink data, thereby improving the performance of the terminal in transmitting uplink data, and further reducing the possibility of occurrence of jamming during the running process of the application program.

For the convenience of understanding the BSR, the relevant description of the BSR is provided herein, specifically as follows:

when a terminal needs to transmit uplink data to a network side device (such as a base station), uplink Resource Block (RB) resources are required, if no RB resources exist, the terminal needs to apply for the RB resources to the base station first, and the terminal sends BSR to the network side device as a common way of applying for the uplink RB resources, and the process is as follows: a terminal inserts a BSR Control Unit in a Packet Data Unit (PDU) of a Media Access Control (MAC) layer to inform a network side device of how much uplink Data currently exist in a certain or a plurality of logic channel groups of the terminal need to be transmitted, and hopes that the network side device can allocate some RB resources to the terminal;

to control the number of bits occupied by the BSR, the third Generation partnership (3 GPP) protocol encodes BSR information: 64 index values (index), namely 0-63, are used to represent different byte ranges of uplink data, so that no matter how much uplink data is transmitted by the terminal, the BSR only needs 6 bits of space to be enough. As shown in table 1, the corresponding relationship between the index value of the BSR agreed for the 3GPP protocol and the byte range of the uplink data, where the byte range of the uplink data is the Buffer Size (BS) value in table 1, for example, an index value of 0 indicates that there is no data in a certain logical channel group to be transmitted, an index value of 63 indicates that there is more than 150 kbytes of data in a certain logical channel group to be transmitted, when there is 30 bytes of data to be transmitted by the terminal, the value of the BSR control unit only needs to be filled in to 8, and so on.

Table 1 table of correspondence between index values and byte ranges of uplink data

When the uplink communication quality is degraded due to the blocking of the transmitting antenna, the uplink data rate correctly received by the network side device may be lower than the data rate that needs to be sent by the application program operated by the terminal, which may cause the uplink BSR of the terminal to be accumulated and maintained at a higher level, that is, the index value of the BSR may become larger. Therefore, whether the uplink communication quality of the current transmitting antenna is degraded or not can be indirectly reflected through the index value of the BSR. Therefore, in step 301, the terminal monitors the buffer status report BSR, which may be a change of the index value of the BSR detected by the terminal.

In step 302, based on the BSR, the M antennas of the N antennas are controlled to be in an activated state, where the terminal may control, according to a change of the index value of the BSR, the M antennas corresponding to the change to be in an activated state.

In some embodiments, the step 302 may include:

determining the number of first antennas in an active state currently in the N antennas under the condition that the index values of the BSR are greater than or equal to a first preset threshold value within a first preset time length;

activating K1 second antennas of the N antennas except the first antenna if the number of the first antennas is less than the N, wherein the sum of the number of the first antennas and K1 is equal to the M.

Here, in a case where the index value of the BSR is greater than or equal to a first preset threshold value within a first preset time period, the terminal may determine that the communication quality of the current transmitting antenna is degraded, so that the terminal controls K1 second antennas to be activated when determining that all antennas are not activated (i.e., the number of first antennas is less than N), even if the number of activated antennas is increased, so that when subsequently selecting a target antenna for replacing the current transmitting antenna, the terminal may select a target antenna from more activated antennas, increase the selectivity of the target antenna, and thereby determine a more appropriate target antenna, and further improve the communication quality after the terminal switches the transmitting antenna.

Illustratively, taking an example that the terminal includes 4 (i.e., N ═ 4) antennas, assuming that the first preset threshold preset by the terminal is BSR _ threshold1 and the first preset time duration is t1 seconds, in a case that the terminal detects that the index value of the BSR is greater than or equal to BSR _ threshold1 and reaches t1 seconds continuously, the terminal determines whether the number of currently activated antennas (i.e., first antennas) of the terminal is less than 4, and if the number of currently activated antennas is less than 4, the terminal controls at least one antenna (i.e., K1 second antennas) in the antennas that are not activated (i.e., second antennas) to be in an activated state.

It should be noted that, when the index values of the BSRs are all greater than or equal to a first preset threshold within a first preset time period and the number of the first antennas is equal to N, the terminal does not need to perform an antenna activation action again because the antennas of the terminal in the active state reach the upper limit at this time.

In addition, the value K1 may be a preset fixed value, for example, the value K1 may be preset to 1, that is, the terminal controls only 1 second antenna to be in an active state from among the second antennas that are not in an active state at a time; alternatively, the value K1 may be a variable value determined according to a preset rule, specifically, the value K1 may be determined according to the number of first antennas currently in an active state, for example, if the number of currently active antennas is 1, the number of currently active antennas is increased from 1 antenna to 2 antennas; if the number of the currently activated antennas is 2, increasing the number of the currently activated antennas from 2 to 4, and the like.

It should be noted that, the terminal may activate the antennas according to a preset priority order of the antennas, for example, when the terminal includes the antenna 1, the antenna 2, the antenna 3, and the antenna 4, and the priorities of the antenna 1, the antenna 2, the antenna 3, and the antenna 4 are sequentially reduced, when the currently activated antennas of the terminal are the antenna 1 and the antenna 2, if it is necessary to activate one antenna again, the antenna 3 is activated, and so on.

In another embodiment, the step 302 may include:

determining the number of third antennas which are currently in an activated state in the N antennas under the condition that the index values of the BSR are less than or equal to a second preset threshold within a second preset time period;

turning off K2 of the third antennas if the number of the third antennas is greater than 1, wherein the difference between the number of the third antennas and the K2 is equal to M.

Here, when the index values of the BSRs within the second preset time period are all less than or equal to the second preset threshold, and when at least one antenna (i.e., a third antenna) currently exists in the terminal and is in an active state, the terminal may turn off some antennas (i.e., K2 of the third antennas) in the at least one antenna that is in the active state, thereby reducing the number of antennas that are in the active state and achieving reduction of power consumption of the terminal.

Exemplarily, taking the terminal including 4 antennas as an example, assuming that the second preset threshold preset by the terminal is BSR threshold2 and the second preset duration is t2 seconds, in the case that the terminal detects that the index value of the BSR is less than or equal to BSR threshold2 and reaches t2 seconds continuously, the terminal determines whether the number of currently activated antennas (i.e., third antennas) of the terminal is greater than 1, and if the number of currently activated antennas is greater than 1, the terminal controls at least one of the antennas that are activated (i.e., K2 third antennas) to be turned off.

It should be noted that the first preset threshold, the second preset threshold, the first preset duration and the second preset duration may be fixed values preset in the terminal; alternatively, the value may be dynamically adjusted according to a preset rule.

In some embodiments, before determining the number of the first antennas currently in an active state in the N antennas when it is monitored that the index value of the BSR is continuously greater than or equal to a first preset threshold for a first preset time period, the method may further include:

determining the service type of uplink data of the terminal;

and determining a preset threshold and a preset time length corresponding to the service type, wherein the preset threshold comprises a first preset threshold and a second preset threshold, and the preset time length comprises a first preset time length and a second preset time length.

Here, the preset threshold may include that the terminal may determine a first preset threshold, a second preset threshold, a first preset duration, and a second preset duration according to the service type of the uplink data, so that the condition for activating the antenna may be dynamically adjusted according to the service type, a more appropriate target antenna may be determined, and the communication quality after the terminal switches the transmitting antenna is further improved.

For example, for a service with a high real-time requirement, such as a game service, etc., the first preset threshold, the second preset threshold, the first preset duration and the second preset duration are all small; for services with low real-time requirements, such as data transmission services, the first preset threshold, the second preset threshold, the first preset duration and the second preset duration are all large.

In addition, in the case where the number of the third antennas is equal to 1, at which time the terminal has used the fewest antennas, the terminal may not change the number of antennas in the active state and continue to monitor the change of the BSR over time.

In this embodiment, the terminal may perform turning off K2 third antennas as long as it is determined that, within a second preset time period, the index values of the BSRs are all smaller than or equal to a second preset threshold, and the number of the third antennas is greater than 1.

Alternatively, in some embodiments, turning off K2 of the third antennas includes:

acquiring a first communication quality parameter of the third antenna of the N antennas;

determining whether the communication quality of the terminal meets a preset condition based on a first communication quality parameter of the third antenna in the N antennas;

and turning off K2 third antennas under the condition that the communication quality of the terminal meets a preset condition.

Here, the terminal turns off part of the third antennas in the active state only when the communication quality of the terminal is determined to satisfy the preset condition based on the first communication quality parameter of the third antenna among the N antennas, so that the risk of communication quality deterioration caused by turning off the antennas in the active state can be reduced, and the communication quality of the terminal can be ensured.

It should be noted that the first communication quality parameter may be any parameter capable of characterizing the communication quality of each antenna, for example, the first communication quality parameter may include at least one of signal Received quality (RSRQ), signal to noise ratio (SNR), Mutual Information (MI), Reference Signal Received Power (RSRP), Received Signal Strength Indicator (RSSI), and the like.

In addition, the above-mentioned preset condition may be any condition for determining whether or not the communication quality of the remaining third antenna is deteriorated.

In some embodiments, the first communication quality parameter may comprise a reference signal received quality, RSRQ, and/or a signal to noise ratio, SNR;

the turning off K2 of the third antennas under the condition that the communication quality of the terminal meets a preset condition includes:

determining a maximum first communication quality parameter among the first communication quality parameters of remaining third antennas of the N antennas except for K2 third antennas;

calculating the difference value between the maximum first communication quality parameter and the first communication quality parameter of the current transmitting antenna;

and under the condition that the difference is greater than or equal to a preset difference, determining that the communication quality of the terminal meets a preset condition, and closing the K2 third antennas.

Here, the terminal may turn off the partial antennas in the active state (i.e., K2 third antennas) when the difference between the maximum first communication quality parameter of the remaining third antennas and the first communication quality parameter of the current transmitting antenna of the terminal is greater than or equal to the preset difference, and further may reduce the risk of communication quality deterioration caused by turning off the partial antennas.

Exemplarily, in the case that the number of the third antennas is greater than 1, calculating:

delta_RSRP＝RSRPmax–RSRP0

wherein RSRPmax represents the maximum RSRP among the remaining candidate antennas (i.e., the remaining third antennas) after the partial antennas (i.e., K2 third antennas) are turned off;

RSRP0 represents the RSRP of the current transmit antenna of the terminal;

and under the condition that the delta _ RSRP is higher than the preset difference value, the communication quality of the terminal is not deteriorated after the partial antennas are closed, and the terminal closes the partial antennas.

It should be noted that, in the case that the terminal determines that the communication quality of the terminal does not satisfy the preset condition based on the first communication quality parameter of the third antenna of the N antennas, the terminal may determine that the communication quality may be degraded if the terminal turns off a part of the antennas in the active state, and at this time, the terminal may not perform turning off the antennas in the active state.

In addition, the value K2 may be a preset fixed value, for example, it may be preset that K2 is 1, that is, the terminal controls only 1 third antenna to be turned off from the third antennas in the active state at a time; alternatively, the value K2 may be a variable value determined according to a preset rule, specifically, the value K2 may be determined according to the number of third antennas currently in an active state, for example, if the number of currently active antennas is 4, the number of 4 antennas in an active state is reduced to 2; if the number of the currently activated antennas is 2, the number of the currently activated antennas is reduced from 2 to 1, and so on.

Of course, the terminal may turn off the antennas according to a preset priority order of the antennas, for example, when the terminal includes the antenna 1, the antenna 2, the antenna 3, and the antenna 4, and the priorities of the antenna 1, the antenna 2, the antenna 3, and the antenna 4 are sequentially reduced, if an antenna needs to be turned off, the antenna 4 is turned off first, and the like when the currently activated antenna of the terminal is the antenna 1, the antenna 2, the antenna 3, and the antenna 4.

In step 303, after the terminal controls the M antennas to be in the activated state, the terminal may determine a target antenna among the M antennas, and switch a transmitting antenna of the terminal to the target antenna, so as to enhance the communication quality.

It should be noted that the number of the antennas in the active state may be only one, that is, M is 1, for example, in a case that the index values of the second preset duration BSR are all less than or equal to the second preset threshold, and the number of the third antennas is 2, the terminal turns off 1 third antenna, and the third antenna is an antenna currently transmitted by the terminal, and then the terminal may use the remaining one antenna in the active state (i.e., the target antenna) as its new transmitting antenna while turning off the third antenna.

In addition, when the M antennas are a plurality of antennas, the target antenna may be any one of the M antennas, which has higher communication quality than that of a current transmitting antenna of the terminal.

In some embodiments, M is greater than 1;

the transmitting antenna of the terminal is switched to a target antenna in the M antennas, including

Detecting second communication quality parameters of the M antennas, wherein the second communication quality parameters comprise Reference Signal Received Quality (RSRQ) and/or signal-to-noise ratio (SNR);

determining an antenna with the largest second communication quality parameter in the M antennas as a target antenna;

and controlling the transmitting antenna to be switched to the target antenna.

Here, the terminal may determine an antenna having the largest RSRQ and/or SNR among the M antennas as a target antenna, thereby optimizing communication quality of the terminal after switching the transmit antennas.

It should be noted that the target antenna may be one or more antennas, for example, as shown in fig. 1, in the case that the current transmitting antenna is ANT2, the target antenna may be any one of ANT0 or ANT 1; alternatively, in the case where the current transmitting antennas are ANT1 and ANT2, the target antennas may be ANT0 and ANT1, and so on.

In the embodiment of the invention, the buffer status report BSR of the terminal is monitored; controlling M antennas of the N antennas to be in an activated state based on the BSR, wherein M is a positive integer and is less than or equal to N; and the transmitting antenna of the terminal is switched to a target antenna in the M antennas, wherein the communication quality of the target antenna is higher than that of the transmitting antenna before the terminal is switched. Therefore, under the scene that the communication quality of the current transmitting antenna of the terminal is reduced, the current transmitting antenna can be switched to the target antenna with higher communication quality to transmit the uplink data, the performance of the terminal for transmitting the uplink data is improved, and the possibility of blocking during the operation process of the application program is further reduced.
