If the terminal moves or the terminal antenna is blocked, a beam failure event may occur, and a beam recovery process is triggered. At this time, a communication interruption of T × n seconds may occur, where T is the sum of the period of the downlink synchronization signal transmitted by the base station and the time window length of the beam scanning, and n is the number of the terminal antennas. This is because the period of downlink synchronization signal transmission by the base station is, for example, 20ms, and the time window length of beam scanning is 5ms, i.e. the beam recovery process will take at least 25 ms. Meanwhile, in the worst case, if the antenna of the terminal is traversed before finding an unshielded or better antenna, if the terminal has 4 antennas, communication interruption of 100ms (4 × 25ms) is caused at least in the prior art on the premise of ignoring antenna switching time.

The method for switching antennas according to the embodiments of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

As shown in fig. 2, an embodiment of the present invention provides a method 200 for switching antennas, which may be performed by a terminal device, in other words, may be performed by software or hardware installed in the terminal device, and the method includes the following steps:

s202: the current beam received by the active antenna is determined.

The terminal device is provided with a plurality of antennas, and as shown in fig. 1a, for example, a layout scheme of millimeter wave antennas of the terminal is as follows: the mobile terminal has a left antenna a102, a top antenna a101, a right antenna a104, and a back antenna a103, wherein the left and right antennas can be adjusted in position on two more sides according to actual conditions. The working antenna is one of the multiple antennas, the working antenna can receive multiple beams, the angle value of each beam is different, and the current beam is used for receiving downlink information currently sent by the network equipment.

For example, the terminal selects one antenna as an operating antenna, such as a101, and the other antennas as alternative antennas, such as a102, a103, and a104, according to a predetermined algorithm.

The base station transmits a downlink signal to the terminal device via the current beam AB1013 of the active antenna a101, and the terminal device receives the downlink signal generated by the current beam AB1013 of the antenna a101, whereby in this step the terminal device determines the current beam of the active antenna, e.g. the current beam AB1013 of the antenna a 101.

S204: and determining a target angle between the target beam and the current beam according to the current attitude information of the terminal equipment and the angle information of the current beam.

The terminal device communicates with the base station via the current beam AB1013 of the antenna a 101. However, when the terminal device moves or the terminal antenna is blocked by the user, a beam failure event may occur, triggering the beam recovery process. At this time, a communication interruption of T × n seconds may occur, where T is the sum of the period of the base station transmitting the downlink synchronization signal and the time window length of the beam scanning, and n is the number of the terminal antennas. This is because the period of the downlink synchronization signal transmitted by the base station is, for example, 20ms, and the time window length of the beam scanning is 5ms, i.e., the beam recovery process will take at least 25 ms. Meanwhile, in the worst case, if the antenna of the terminal is traversed before finding an unobstructed or better antenna, for example, fig. 1a shows that the terminal has 4 antennas, 100ms (4 × 25ms) communication interruption is caused on the premise of ignoring antenna switching time.

In view of this, in this step, when the terminal device moves or the terminal antenna is blocked by the user, the target angle between the target beam and the current beam may be determined according to the current posture information of the terminal device and the angle information of the current beam. As shown in fig. 1b, on the one hand, the angle information of the current beam may be used as a reference, for example, the direction of the current beam is defined as the angle information of the current beam is 0 °. On one hand, in the case that the terminal device has a position movement, the current attitude information of the terminal device may be measured or determined by a component on the terminal device, where the component includes at least one of a gyroscope, an acceleration sensor, and an electronic compass, and the information measured by the component may include: at least one of gyroscope angle, acceleration sensor information, and electronic compass pointing direction information. Furthermore, the current position of the terminal device can be determined from the information measured by the above components, the rotation angle of the terminal device can be determined based on the current position of the terminal device, and the target angle β between the target beam and the current beam can be determined based on the angle information (for example, 0 °) of the current beam.

S206: and determining a target beam according to the target angle and the target corresponding relation.

The target corresponding relation is the corresponding relation between the angle value and the wave beams which can be received by the working antenna. Table 1 shows an example of the target correspondence relationship.

TABLE 1

Table 2 shows the correspondence between the current attitude information, the component measurement information, the angle value, and each beam of the terminal device.

The target corresponding relation may be preset by the terminal, determined by the terminal through calculation, acquired by the terminal or agreed by a protocol, and the like.

For example, if the current beam AB1013 of the operating antenna is determined in step S202 and the target angle β between the target beam and the current beam is-12 degrees in S204, the target beam AB1011 can be determined in this step based on the angle β of-12 degrees and the correspondence between the angle values shown in table 1 and the beams on the operating antenna. As shown in fig. 1b, after the terminal position is changed, when AB1011 is located at the position AB1013 before the terminal position is changed, it can be seen that the beam failure recovery is performed by using the target beam AB1011, and communication can be realized instead of AB1013.

For another example, if the current beam AB1013 of the operating antenna is determined in step S202 and the target angle β between the target beam and the current beam is 10 degrees in S204, then the target beam AB1014 can be determined in this step based on β being-10 degrees and the correspondence between the angle values shown in table 2 and the beams on the operating antenna.

Therefore, when the beam failure recovery is needed, the target beam for the beam failure recovery can be immediately determined based on the target angle and the target corresponding relation, the beam failure recovery is carried out by using the target beam as AB1011, and the communication failure caused by traversing a plurality of antenna beams can be avoided without traversing all n beams.

Therefore, in the method for switching antennas provided in the embodiment of the present invention, a current beam received by a working antenna is determined, where the working antenna is one of multiple antennas, the working antenna may receive multiple beams, an angle value of each beam is different, and the current beam is used to receive downlink information currently sent by a network device; determining a target angle between a target wave beam and a current wave beam according to the current attitude information of the terminal equipment and the angle information of the current wave beam; and determining a target wave beam according to the target angle and the target corresponding relation, wherein the target corresponding relation is the corresponding relation between the angle value and the wave beam which can be received by the working antenna, so that communication interruption possibly caused by wave beam failure recovery can be avoided, targeted antenna wave beam switching is realized, the efficiency of executing wave beam switching and millimeter wave antenna switching by the mobile terminal is improved, the sacrifice of network speed caused by switching measurement judgment and the like is further reduced, and the internet experience of a terminal user is improved.

As shown in fig. 3, an embodiment of the present invention provides a method 300 for switching antennas, which may be performed by a terminal device and/or a network device, in other words, may be performed by software or hardware installed in the terminal device and/or the network device, and includes the following steps:

s3021: a plurality of first beam signals transmitted by a network device are received.

The network device sends multiple first beam signals, for example, beams BB101 to BB10n issued by the base station, where the beams may be broadcast beams before initial access or traffic channel beams in a service process. The terminal equipment receives a plurality of first beam signals transmitted by the network equipment.

S3022: and measuring and feeding back first signal quality information of each first beam signal to the network equipment.

Wherein the first signal quality information includes: the received signal strength of each first beam signal, the signal-to-noise ratio of each first beam signal, etc. For example, { BB101: RSRP101, SNR101, … } { BB102: RSRP102, SNR102, … } { BB10n: RSRP10n, SNR10n, … }.

S3023: a plurality of second beam signals for traversing the active antenna are transmitted to the network device.

For example, the mobile terminal transmits beams AB1011 to AB101n passing through the antenna module a101, and in one implementation, the working range of the working antenna may be, for example, 90 degrees, for example, the beams cover a range of positive and negative 45 degrees included angles perpendicular to the antenna. The range between ray a and ray b in fig. 1a is the operating range of a 101. If the number of the second beam signals is 15, for example, the angle change interval is determined to be 6 degrees. The interval between rays b and 2 in fig. 1a is the 1 degree transition interval.

The base station receives beams AB 1011-AB 101n transmitted by the mobile terminal and records the received signal strength, signal-to-noise ratio and other information indicating the received signal quality of each millimeter beam; { AB1011: RSRP1011, SNR1011, … } { AB102: RSRP1012, SNR1012, … } { AB101n: RSRP101n, SNR101n, … }. The base station may select at least one of the beams as the current beam of the working antenna based on the received downlink signal quality information { BB10n: RSRP10n, SNR10n, … } fed back by the mobile terminal, for example, but not limited to, selecting the beam with the best communication quality to send downlink information to the mobile terminal, for example, as shown in fig. AB1013.

S3024: and determining the current wave beam of the working antenna through downlink information sent by the network equipment.

And receiving downlink information sent by the network equipment, and determining the current wave beam of the working antenna according to the downlink information sent by the network equipment. The terminal receives the downlink information transmitted by the network equipment and determines the beam used for transmitting the downlink information to be AB1013, and therefore, the AB1013 is determined to be the current beam of the working antenna.

The current beam of the working antenna is determined by the network device according to the first signal quality information and second signal quality information of a second beam signal, wherein the second signal quality information of the second beam signal comprises: a received signal strength of each second beam signal or a signal-to-noise ratio of each second beam signal.

In addition, the steps S3021 to 3024 may also adopt the description related to step S202 in the embodiment of fig. 2, and are not described herein again.

S304: and determining a target angle between the target beam and the current beam according to the current attitude information of the terminal equipment and the angle information of the current beam.

S306: and determining a target beam according to the target angle and the target corresponding relation.

The descriptions of steps S304-S306 that may be used with steps S204-206 are not repeated herein.

Therefore, in the method for switching antennas provided in the embodiment of the present invention, a current beam received by a working antenna is determined, where the working antenna is one of multiple antennas, the working antenna may receive multiple beams, an angle value of each beam is different, and the current beam is used to receive downlink information currently sent by a network device; determining a target angle between a target wave beam and a current wave beam according to the current attitude information of the terminal equipment and the angle information of the current wave beam; and determining a target beam according to the target angle and the target corresponding relation, wherein the target corresponding relation is the corresponding relation between the angle value and the beam which can be received by the working antenna, and the communication interruption which possibly occurs when the beam is failed to recover can be avoided.

Therefore, in the method for switching antennas provided by the embodiment of the present invention, a plurality of first beam signals sent by a network device are received; measuring and feeding back first signal quality information of each first beam signal to the network equipment, and sending a plurality of second beam signals for traversing the working antenna to the network equipment; receiving downlink information sent by the network equipment, determining the current wave beam of the working antenna through the downlink information sent by the network equipment, enabling the base station to determine the current wave beam of the working antenna according to the signal quality, and determining a target angle by taking the angle information of the current wave beam as a reference so as to determine a target wave beam.

As shown in fig. 4, an embodiment of the present invention provides a method 400 for switching antennas, which may be performed by a terminal device, in other words, by software or hardware installed in the terminal device, and includes the following steps:

s402: the current beam received by the active antenna is determined.

Step S202 in the embodiment of fig. 2 may be adopted in this step, or the descriptions of steps S3021 to 3024 in the embodiment of fig. 3 are not repeated here.

S403: and determining the target corresponding relation.

The target corresponding relation is the corresponding relation between the angle value and the wave beams which can be received by the working antenna.

The method comprises the following steps: determining an angle change interval according to the working range of the working antenna and the number of the second wave beam signals; and determining the corresponding relation of the target according to the information of the current beam and the angle change interval. Wherein the information of the current beam comprises: angle information of the current beam and the number of the current beam.

In one implementation mode, the current beam is taken as the center, the difference value between the number of each beam and the current beam number is calculated, and the corresponding angle value of each beam is determined according to the product of the difference value and the angle change interval, so that the corresponding relation between the angle value and each beam on the working antenna is determined.

In one implementation, the working range of the working antenna is, for example, 90 degrees, the number n of the second beam signals is, for example, 15 (n = 15), and the angle change interval is 6 degrees, that is, the angle change interval = working range of the working antenna/the number of the second beam signals.

According to the information of the current beam, for example, if the current beam number is AB1013, the angle information of AB1013 is 0 degree, each angle change interval is 6 degrees, the angle of AB1011 is-12 degrees, the angle of AB1012 is-6 degrees, the angle of AB1013 is 0 degree, the angle of AB1014 is 6 degrees, the angle of AB1015 is 12 degrees, and the angle of AB1016 is 18 degrees … … AB10115 is 78 degrees. That is, the angle of AB101n is (n-3) × 6 degrees. As shown in table 1. For example, AB1011 has a difference value of-2 between the beam signal number 1011 and the current beam number 1013, and a product of the difference value and the angle change interval of 6 degrees is-12 degrees. The correspondence between the angular value-12 degrees and the beam AB1011 on the active antenna is thus determined. The numerical values in the following examples are not described in detail.

For another example, if the current beam is AB1012, the angle information of AB1012 is set to 0 degree, each angle change interval is 6 degrees, the angle of AB1011 is-6 degrees, the angle of AB1012 is 0 degree, the angle of AB1013 is 6 degrees, the angle of AB1014 is 12 degrees, and the angle of AB1015 is 18 degrees … … AB10115 is 78 degrees. That is, the angle of AB101n is (n-2) × 6 degrees.

In one implementation, the beams in the rank n 'correspond to an angular value of (n' -n) × 6 degrees in the target correspondence, where n is the rank of the current beam. For example, if the current beam is AB1018, that is, if the rank n of the current beam is 8, then the rank of the beam is 6 (n' = 6), and the corresponding angular value in the target correspondence is (6-8) × 6= -12 degrees.

S404: and determining a target angle between the target beam and the current beam according to the current attitude information of the terminal equipment and the angle information of the current beam.

S406: and determining a target beam according to the target angle and the target corresponding relation.

Steps S404-S406 can be the same as steps S202-204 described in the embodiment of FIG. 2 and will not be repeated herein.

Therefore, in the method for switching antennas provided in the embodiment of the present invention, a current beam received by a working antenna is determined, where the working antenna is one of multiple antennas, the working antenna may receive multiple beams, an angle value of each beam is different, and the current beam is used to receive downlink information currently sent by a network device; determining a target angle between a target wave beam and a current wave beam according to the current attitude information of the terminal equipment and the angle information of the current wave beam; and determining a target beam according to the target angle and the target corresponding relation, wherein the target corresponding relation is the corresponding relation between the angle value and the beam which can be received by the working antenna, and communication interruption possibly occurring when the beam fails to recover can be avoided.

As shown in fig. 5, an embodiment of the present invention provides a method 500 for switching antennas, which may be performed by a terminal device, in other words, by software or hardware installed in the terminal device, and the method includes the following steps:

s502: the current beam received by the active antenna is determined.

S504: and determining a target angle between the target beam and the current beam according to the current attitude information of the terminal equipment and the angle information of the current beam.

Step S504 can adopt the description of step S204 in the embodiment of fig. 2, which is not described herein again.

S506: and under the condition that the target angle exceeds the working range of the working antenna, switching other antennas of the terminal equipment to the current working antenna.

Referring to fig. 1b, if the target angle exceeds the operating range of the operating antenna, for example, exceeds-12 degrees shown in table 1, the other antennas of the terminal device, for example, a102, are switched to the current operating antenna. And performs the steps of the embodiment of fig. 2-5 based on the beams of a102.

If the target angle exceeds the working range of the working antenna, for example, (n-3) × 6 degrees AB101n shown in table 1, the other antennas of the terminal device, for example, a104, are switched to the current working antenna. And performs the steps of the embodiment of fig. 2-5 based on the beams of a104.

In one implementation, it is understood that the target angle has a first correspondence with the operating antenna, e.g., the target angle exceeds-12 degrees as shown in table 1, and corresponds to antenna a102. Alternatively, for example, -13 degrees, -14 degrees may be defined as being over-12 degrees. The target angle exceeds (n-3) × 6 degrees shown in table 1, which corresponds to antenna a104.
