The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

In the following description process, firstly, we will explain from the cooperative implementation of the user equipment side and the macro base station side, and finally explain from the implementation of the user equipment side and the macro base station side respectively, but this does not mean that the two must be implemented cooperatively. In the above, when the user equipment side and the macro base station side are implemented separately, the problems existing on the user equipment side and the macro base station side respectively are also solved. Only when the two are used in combination, better technical effects will be obtained.

As shown in FIG. 1 , an embodiment of the present invention provides a system for switching beam pairs, and the system includes a user equipment 10 and a macro base station 20;

The user equipment 10 is configured to determine beam pair information when the reference signal power value on the original beam pair used for communication with the original transmitting unit satisfies the switching condition; report the beam pair information to the macro base station 20, so that the macro base station Station 20 switches beam pairs according to the beam pair information.

The macro base station 20 is configured to determine a target beam pair according to the beam pair information after receiving the beam pair information reported by the user equipment 10, wherein the beam pair information is used by the user equipment 10 in communicating with the original transmitting unit It is determined when the reference signal power value on the original beam pair satisfies the switching condition; and the switching operation is performed according to the target beam pair.

The user equipment 10 and the original transmitting unit perform high-frequency communication through a beam pair formed by a beam of the user equipment 10 and a beam of the original transmitting unit. The user equipment 10 can measure the beam pair, that is, beam measurement, and obtain the original beam pair The power value of the upper reference signal.

It should be noted that the beams involved in the present invention refer to analog beams, and analog beams refer to beams formed after adjusting the phases of antennas through radio frequency devices (such as phase shifters), and beam pairs also refer to beams formed by user equipment 10. A beam pair formed by one analog beam and one analog beam of the transmitting unit.

A transmitting unit refers to a wireless device with multiple analog beams, and a single or multiple transmitting units can be equivalent to a base station.

The user equipment 10 may perform multiple beam measurements, either periodically or aperiodically.

Wherein, the switching conditions include but are not limited to some or all of the following conditions:

The power value of the reference signal on the original beam pair is lower than the power threshold;

Among the results of detecting the power value of the reference signal on the original beam pair multiple times, the number of times the power value of the reference signal on the original beam is lower than the threshold is greater than the threshold.

The switching conditions are introduced respectively as follows:

1. The power value of the reference signal on the original beam pair is lower than the power threshold;

A power threshold is set for the power value of the reference signal. When the user equipment 10 detects that the power value of the reference signal on the original beam pair communicated between the user equipment 10 and the original transmitting unit is lower than the power threshold, it means that the user equipment 10 and the original transmitting unit are connected to each other at this time. The communication quality between the original transmitting units is seriously affected, and it is necessary to reselect the beam pair for the user equipment 10 to ensure the communication quality of the user equipment 10 .

2. Among the results of multiple detections of the power value of the reference signal on the original beam pair, the number of times the power value of the reference signal on the original beam is lower than the threshold is greater than the threshold;

When the user equipment 10 performs multiple detections on the reference signal on the original beam pair, among the multiple detection results, the number of times the power value of the reference signal on the original beam pair is lower than the threshold is greater than the threshold, indicating that the user equipment 10 and The communication quality between the original transmitting unit is seriously affected, and because the power value of the reference signal on the original beam is lower than the threshold for many times in the multiple measurement results, the communication quality between the user equipment 10 and the original transmitting unit is difficult. To return to normal, it is necessary to reselect the beam pair for the user equipment 10 to ensure the communication quality of the user equipment 10 .

Among the multiple measurement results, the reference signal power values of multiple continuous measurements may be lower than the threshold, or the reference signal power values of discontinuous multiple measurements may be lower than the threshold.

When the power value of the reference signal on the original beam pair satisfies the above switching conditions, the user equipment 10 can determine the beam pair information, where there are two types of beam pair information:

In the first type, the beam pair information includes the beam pair information corresponding to the original beam pair:

At this time, the user equipment 10 cannot determine a candidate target beam pair, and the user equipment 10 determines that no suitable beam pair can be used as a candidate target beam pair.

The user equipment 10 will receive the reference signal sent by several transmitting units (including the original transmitting unit) through the beam pair, and detect the power value of the reference signal. If the power value of the reference signal on the beam pair is greater than the threshold, the beam pair can be as an alternative target beam pair. If the power value of the reference signal on the beam pair is not greater than the threshold, the beam pair is not used as a candidate target beam pair. If there is currently no beam pair with a reference signal power value greater than the threshold, when the reference signal power value of the original beam pair satisfies the handover condition and the communication quality between the user equipment 10 and the original transmitting unit degrades, the user equipment 10 does not report the candidate target beam The corresponding beam pair information is sent to the macro base station 20 .

In the second type, the beam pair information includes beam pair information corresponding to the original beam pair and the candidate target beam pair.

At this time, the user equipment 10 can determine a candidate target beam pair, and the user equipment 1 determines that there is a suitable beam pair that can be used as a candidate target beam pair.

Alternative target beam pairs may be some or all of the following beam pairs:

A standby beam pair corresponding to the user equipment 10;

The reference signal power value is larger than the threshold beam pair.

The user equipment 10 may use a spare beam pair stored in advance by the user equipment 10 as the candidate target beam pair; the user equipment 10 may use a beam pair whose reference signal power value is greater than a threshold as the candidate target beam pair Yes; the user equipment 10 may use the spare beam pair corresponding to the user equipment 10 and the beam pair whose reference signal power value is greater than a threshold as the candidate target beam pair.

The following three situations are introduced:

Case 1, the user equipment 10 may use the spare beam pair corresponding to the user equipment 10 as the candidate target beam pair;

The user equipment 10 can pre-store the beam pairs used for communication between the transmitting unit and the user equipment 10, and use these beam pairs as backup beam pairs. When the reference signal power value of the original beam pair meets the switching condition, the user equipment 10 and the original transmitting beam pair When the communication quality between the units degrades, the spare beam pair is used as a candidate target beam pair and the corresponding beam pair information is reported to the macro base station 20 .

Among them, the standby beam pair is determined by the user equipment 10 according to the power value of the reference signal on the beam pair between several transmitting units (including the original transmitting unit) and the user equipment 10; the user equipment 10 will receive reference signal, and detect the power value of the reference signal. If the power value of the reference signal on the beam pair is high or exceeds a certain threshold, the beam pair can be used as a backup beam pair. It should be noted that the backup beam pair can be based on The detection of the power value of the reference signal is updated in real time.

Case 2, the user equipment 10 may use a beam pair whose reference signal power value is greater than a threshold as the candidate target beam pair;

The user equipment 10 will receive the reference signal sent by several transmitting units (including the original transmitting unit) through the beam pair, and detect the power value of the reference signal. If the power value of the reference signal on the beam pair is greater than the threshold, the beam pair can be as an alternative target beam pair. When the reference signal power value of the original beam pair satisfies the switching condition and the communication quality between the user equipment 10 and the original transmitting unit decreases, the beam pair whose reference signal power value is greater than the threshold is used as the candidate target beam pair and the corresponding beam pair The information is reported to the macro base station 20 .

In case three, the user equipment 10 may use the backup beam pair corresponding to the user equipment 10 and the beam pair whose reference signal power value is greater than a threshold as the candidate target beam pair;

The user equipment 10 will receive the reference signal sent by several transmitting units (including the original transmitting unit) through the beam pair, and detect the power value of the reference signal. If the power value of the reference signal on the beam pair is greater than the threshold, the beam pair can be As an alternative target beam pair; when the reference signal power value of the original beam pair satisfies the switching condition and the communication quality between the user equipment 10 and the original transmitting unit decreases, the beam pair whose reference signal power value is greater than the threshold and the pre-stored backup The beam pair is used as a candidate target beam pair and the corresponding beam pair information is reported to the macro base station 20 .

It should be noted that there may be one or more candidate target beam pairs.

After determining the beam pair information, the user equipment 10 reports the beam pair information to the macro base station 20, so that the macro base station 20 determines a target beam pair according to the beam pair information.

The beam pair information includes, but is not limited to, transmitting unit information corresponding to the beam pair, beam pair indication information, and a power value of a reference signal on the beam pair. The form of reporting information can be a signaling containing N fields, and each field is written with beam pair information corresponding to a beam pair; as shown in Figure 2, if the number of candidate target beam pairs is one, the signal The order contains two fields; as shown in FIG. 3 , if the number of candidate target beam pairs is N, the number of fields in the signaling is N+1.

The beam pair indication information is used to indicate identification information of the beam pair, so as to distinguish different beam pairs.

It should be noted that the power value of the reference signal on the beam pair included in the beam pair information can facilitate the macro base station 20 to determine the target beam pair according to the information, if the beam pair information does not include the power value of the reference signal on the beam pair value, the macro base station 20 can detect the reported candidate target beam pair in real time and determine the target beam pair according to the detection result; there are many detection methods, for example, it can send a detection instruction to the user equipment 10, and the user equipment 10 can perform the detection. detection, and then report the detection result to the macro base station 20; it is also possible to send a detection instruction to a device specially used for beam detection, and the device specially used for beam detection performs detection, and then reports the detection result to the macro base station 20.

Since this signaling is sent when the reference signal power value between the user equipment 10 and the original transmitting unit meets the switching condition, that is, when there is a blocking phenomenon, the signaling can be called BI (blockage information, blocking information) signaling .

It should be noted that when the macro base station 20 is a low-frequency macro base station 20, the communication between the user equipment 10 and the macro base station 20 is a low-frequency communication, which is less likely to be affected by the blocking phenomenon, that is, the beam pair information can be relatively smoothly Report to the macro base station 20.

Since high-frequency communication has many advantages, the direct communication with user equipment 10 may be a high-frequency transmitting unit, that is, the original transmitting unit is a high-frequency transmitting unit, and the candidate target transmitting unit corresponding to the candidate target beam pair is High frequency transmitter unit.

Wherein, the low frequency refers to a frequency band lower than 6 GHz, and the high frequency refers to a frequency band higher than 6 GHz.

After receiving the beam pair information reported by the user equipment 10, the macro base station 20 determines the target beam pair according to the beam pair information;

The macro base station 20 performs a switching operation according to the target beam pair.

According to the beam pair information, the macro base station 20 will perform corresponding processing.

In the first type, the beam pair information includes the beam pair information corresponding to the original beam pair:

Since there is no beam pair information corresponding to the candidate target beam pair in the information reported at this time, the macro base station 20 may determine that there is no suitable beam pair as the candidate target beam pair;

The macro base station 20 determines that the beam of the macro base station 20 and the beam of the user equipment 10 are a target beam pair, and the macro base station 20 serves as a target transmitting unit;

In order to ensure that the user equipment 10 can communicate normally, the macro base station 20 can connect to the user equipment 10, and use the beam of the macro base station 20 and the beam of the user equipment 10 as a target beam pair for data transmission. It should be noted that since the macro base station 20 is The low-frequency macro base station 20 has only one beam for the macro base station 20 .

In this case, the macro base station 20 can perform the handover operation in the following three ways:

1. The macro base station 20 transmits the beam pair information corresponding to the original beam pair to the original transmitting unit corresponding to the original beam pair;

Since the original transmitting unit only receives the beam pair information corresponding to the original beam pair, it can be agreed that when only the beam pair information corresponding to the original beam pair is received, the macro base station 20 is used as the target transmitting unit, and the original transmitting unit can be After receiving the information, the beam pair is switched, and the user equipment 10 is notified to stop communicating with the original transmitting unit and start communicating with the macro base station 20 .

2. The macro base station 20 transmits the beam pair information and handover instruction information corresponding to the original beam pair to the original transmitting unit corresponding to the original beam pair;

Wherein, the switching indication information instructs the original transmitting unit to switch the current communication with the user equipment 10 to the macro base station 20, the original transmitting unit may switch the beam pair after receiving the information, and notify the user equipment 10 to stop communicating with the original transmitting unit , start to communicate with the macro base station 20 .

3. The macro base station 20 transmits beam pair information corresponding to the original beam pair and the target beam pair to the original transmitting unit corresponding to the original beam pair;

The original transmitting unit receives the beam pair information corresponding to the original beam pair and the target beam pair, and can determine that the macro base station 20 is used as the target transmitting unit, and the original transmitting unit can switch the beam pair after receiving the information, and notify The user equipment 10 stops communicating with the original transmitting unit, and starts communicating with the macro base station 20 .

In the second type, the beam pair information includes beam pair information corresponding to the original beam pair and the candidate target beam pair:

If the number of candidate target beam pairs reported by the user equipment 10 is one, the macro base station 20 may determine the candidate target beam pair as the target beam pair, or set a target beam pair reference signal power value threshold, if If the reference signal power value of the candidate target beam pair is lower than the target beam pair reference signal power value threshold, the candidate target beam pair is not determined as the target beam pair, and the user equipment 10 is notified that switching is not possible. If the pair reference signal power value is higher than the target beam pair reference signal power value threshold, the candidate target beam pair is determined as the target beam pair.

If the number of candidate target beam pairs reported by the user equipment 10 is multiple, the macro base station 20 may select the beam pair with the largest reference signal power value among the candidate target beam pairs as the target beam pair, or set a target beam pair For the reference signal power value threshold, if multiple candidate target beam pair reference signal power values are lower than the target beam pair reference signal power value threshold, the target beam pair is not determined, and the user equipment 10 is notified that it cannot be switched. If the target beam pair reference signal power value is higher than the target beam pair reference signal power value threshold, the candidate target beam pair that is higher than the target beam pair reference signal power value threshold and has the largest reference signal power value is determined as the target beam pair.

The macro base station 20 transmits beam pair information corresponding to the original beam pair and the target beam pair to the original transmitting unit corresponding to the original beam pair and the target transmitting unit corresponding to the target beam, so that the original transmitting unit and the target transmitting unit switch beams right.

It should be noted that if the target transmitting unit corresponding to the determined target beam pair is the original transmitting unit, that is, another beam of the original transmitting unit and the beam of the user equipment 10 are used as the target beam pair, the macro base station 20 will use the original beam pair The beam pair information corresponding to the target beam pair is transmitted to the original transmitting unit corresponding to the original beam pair, so that the original transmitting unit performs switching between different beams.

For example, the macro base station 20 receives the beam pair information corresponding to the original beam pair and a candidate target beam pair reported by the user equipment 10. Since the user equipment 10 only reports one candidate target beam pair, the macro base station 20 uses the candidate beam pair The target beam pair is determined as the target beam pair, and the macro base station 20 transmits the beam pair information corresponding to the original beam pair and the target beam pair to the original transmitting unit corresponding to the original beam pair and the target transmitting unit corresponding to the target beam; the macro base station 20 receives the beam pair information corresponding to the original beam pair and the three candidate target beam pairs reported by the user equipment 10, then the macro base station 20 may use the beam pair with the largest reference signal power value among the candidate target beam pairs as the target beam pair, The macro base station 20 transmits beam pair information corresponding to the original beam pair and the target beam pair to the original transmitting unit corresponding to the source beam pair and the target transmitting unit corresponding to the target beam.

Based on the same inventive concept, the embodiment of the present invention also provides a user equipment for switching beam pairs. Since the problem-solving principle of the user equipment is similar to the system for switching beam pairs in the embodiment of the present invention, the implementation of the user equipment can be referred to the system The implementation of this method will not be repeated here.

As shown in FIG. 4, the embodiment of the present invention switches the user equipment of the beam pair, and the user equipment includes a first determination module 401 and a reporting module 402:

The first determination module 401 is configured to determine beam pair information when the reference signal power value on the original beam pair used for communication with the original transmitting unit satisfies the switching condition;

The reporting module 402 is configured to report the beam pair information to the macro base station, so that the macro base station performs a switching operation according to the beam pair information.

The first determination module 401 may perform multiple beam measurements, either periodically or aperiodically.

Wherein, the switching conditions include but are not limited to some or all of the following conditions:

The power value of the reference signal on the original beam pair is lower than the power threshold;

Among the results of detecting the power value of the reference signal on the original beam pair multiple times, the number of times the power value of the reference signal on the original beam is lower than the threshold is greater than the threshold.

Among the multiple measurement results, the reference signal power values of multiple continuous measurements may be lower than the threshold, or the reference signal power values of discontinuous multiple measurements may be lower than the threshold.

When the power value of the reference signal on the original beam pair satisfies the above switching conditions, the first determining module 401 can determine the beam pair information, where there are two types of beam pair information:

In the first type, the beam pair information includes the beam pair information corresponding to the original beam pair:

At this time, the first determining module 401 cannot determine a candidate target beam pair, and the first determining module 401 determines that there is no suitable beam pair that can be used as a candidate target beam pair.

The first determination module 401 will receive the reference signal sent by several transmitting units (including the original transmitting unit) through the beam pair, and detect the power value of the reference signal. If the power value of the reference signal on the beam pair is greater than the threshold value, the beam pair as an alternative target beam pair. If the power value of the reference signal on the beam pair is not greater than the threshold, the beam pair is not used as a candidate target beam pair. If there is currently no beam pair with a reference signal power value greater than the threshold value, when the reference signal power value of the original beam pair satisfies the handover condition and the communication quality between the user equipment and the original transmitting unit degrades, the reporting module 402 does not report the candidate target beam pair The corresponding beam pair information is sent to the macro base station.

In the second type, the beam pair information includes beam pair information corresponding to the original beam pair and the candidate target beam pair.

At this time, the first determining module 401 can determine a candidate target beam pair, and the first determining module 401 determines that there is a suitable beam pair that can be used as a candidate target beam pair.

Alternative target beam pairs may be some or all of the following beam pairs:

A standby beam pair corresponding to the user equipment;

The reference signal power value is larger than the threshold beam pair.

The first determination module 401 may use the standby beam pair corresponding to the user equipment as the candidate target beam pair; the first determination module 401 may use a beam pair whose reference signal power value is greater than a threshold as the candidate target beam pair Yes; the first determining module 401 may use the spare beam pair corresponding to the user equipment and the beam pair whose reference signal power value is greater than a threshold as the candidate target beam pair.

It should be noted that there may be one or more candidate target beam pairs.

After the first determining module 401 determines the beam pair information, the reporting module 402 reports the beam pair information to the macro base station, so that the macro base station determines a target beam pair according to the beam pair information.

The beam pair information includes, but is not limited to, transmitting unit information corresponding to the beam pair, beam pair indication information, and a power value of a reference signal on the beam pair. The form of reporting information may be a signaling containing N fields, and each field is written with beam pair information corresponding to a beam pair.

Since the signaling is sent when the reference signal power value between the user equipment and the original transmitting unit satisfies the handover condition, that is, when there is a blocking phenomenon, the signaling can be called BI (blockage information, blocking information) signaling.

It should be noted that when the macro base station is a low-frequency macro base station, the communication between the user equipment and the macro base station is a low-frequency communication, which is less affected by the blocking phenomenon, that is, the beam pair information can be reported to the macro base station relatively smoothly. .

Since high-frequency communication has many advantages, the communication directly with the user equipment can be a high-frequency transmitting unit, that is, the original transmitting unit is a high-frequency transmitting unit, and the target transmitting unit corresponding to the candidate target beam pair is a high-frequency transmitting unit .

Based on the same inventive concept, the embodiment of this discovery also provides a macro base station for switching beam pairs. Since the problem-solving principle of the macro base station is similar to the system for switching beam pairs in the embodiment of the present invention, the implementation of the macro base station can be referred to in the system. implementation, the repetition will not be repeated.

As shown in FIG. 5, the embodiment of the present invention switches the macro base station of the beam pair, and the macro base station includes a second determination module 501 and a processing module 502:

The second determination module 501 is configured to determine a target beam pair according to the beam pair information after receiving the beam pair information reported by the user equipment, wherein the beam pair information is used by the user equipment when communicating with the original transmitting unit It is determined when the reference signal power value on the original beam pair satisfies the handover condition;

The processing module 502 is configured to perform a switching operation according to the target beam pair.

It should be noted that there may be one or more candidate target beam pairs.

The beam pair information includes, but is not limited to, base station information corresponding to the beam pair, beam pair indication information, and a power value of a reference signal on the beam pair. The form of reporting information may be a signaling containing N fields, and each field is written with beam pair information corresponding to a beam pair.

Since the signaling is sent when the reference signal power value between the user equipment and the original transmitting unit satisfies the handover condition, that is, when there is a blocking phenomenon, the signaling can be called BI (blockage information, blocking information) signaling.

It should be noted that when the macro base station is a low-frequency macro base station, the communication between the user equipment and the macro base station is a low-frequency communication, which is less likely to be affected by the blocking phenomenon, that is, the original beam pair and the backup beam pair can be smoothly connected. The beam pair information corresponding to the selected target beam pair is reported to the macro base station.

Since high-frequency communication has many advantages, the communication directly with the user equipment can be a high-frequency transmitting unit, that is, the original transmitting unit is a high-frequency transmitting unit, and the target transmitting unit corresponding to the candidate target beam pair is a high-frequency transmitting unit .

After the second determination module 501 receives the beam pair information reported by the user equipment, the second determination module 501 determines the target beam pair according to the beam pair information;

The processing module 502 performs a switching operation according to the target beam pair.

According to the beam pair information, the macro base station will make corresponding processing.

In the first type, the beam pair information includes the beam pair information corresponding to the original beam pair:

Since there is no beam pair information corresponding to the candidate target beam pair in the information reported at this time, the second determination module 501 may determine that there is no suitable beam pair as the candidate target beam pair;

The second determining module 501 determines that the beam of the macro base station and the beam of the user equipment are a target beam pair, and the macro base station serves as a target transmitting unit;

In this case, the processing module 502 may perform the switching operation in the following three ways:

1. The processing module 502 transmits the beam pair information corresponding to the original beam pair to the original transmitting unit corresponding to the original beam pair;

2. The processing module 502 transmits the beam pair information and switching instruction information corresponding to the original beam pair to the original transmitting unit corresponding to the original beam pair;

3. The processing module 502 transmits beam pair information corresponding to the original beam pair and the target beam pair to the original transmitting unit corresponding to the original beam pair;

In the second type, the beam pair information includes beam pair information corresponding to the original beam pair and the candidate target beam pair:

The second determination module 501 determines the beam pair with the largest reference signal power value among the candidate target beam pairs as the target beam pair.

If the number of candidate target beam pairs reported by the user equipment is one, the second determination module 501 may determine the candidate target beam pair as the target beam pair, or set a target beam pair reference signal power value threshold, If the reference signal power value of the candidate target beam pair is lower than the reference signal power value threshold of the target beam pair, the candidate target beam pair is not determined as the target beam pair, and the user equipment is notified that it cannot be switched. If the pair reference signal power value is higher than the target beam pair reference signal power value threshold, the candidate target beam pair is determined as the target beam pair.

If the number of candidate target beam pairs reported by the user equipment is multiple, the second determination module 501 may select the beam pair with the largest reference signal power value among the candidate target beam pairs as the target beam pair, or set a target beam pair Beam pair reference signal power value threshold. If multiple candidate target beam pair reference signal power values are lower than the target beam pair reference signal power value threshold, the target beam pair is not determined and the user equipment is notified that it cannot be switched. If there is an alternative If the target beam pair reference signal power value is higher than the target beam pair reference signal power value threshold, the candidate target beam pair that is higher than the target beam pair reference signal power value threshold and has the largest reference signal power value is determined as the target beam pair.

Based on the same inventive concept, the embodiment of this discovery also provides a method for switching beam pairs. Since the problem-solving principle of this method is similar to the system for switching beam pairs in the embodiment of the present invention, the implementation of this method can refer to the implementation of the system. Repeat The place will not be repeated.

As shown in FIG. 6, an embodiment of the present invention provides a method for switching a beam pair, the method including:

Step 601: when the power value of the reference signal on the original beam pair used by the user equipment to communicate with the original transmitting unit satisfies the handover condition, determine the beam pair information;

Step 602: The user equipment reports the beam pair information to the macro base station, so that the macro base station performs a switching operation according to the beam pair information.

The user equipment and the original transmitting unit perform high-frequency communication through a beam pair formed by one beam of the user equipment and one beam of the original transmitting unit. The user equipment can measure the beam pair, that is, beam measurement, and obtain the reference signal on the original beam pair. power value.

The user equipment can perform multiple beam measurements, either periodically or aperiodically.

Wherein, the switching conditions include but are not limited to some or all of the following conditions:

The power value of the reference signal on the original beam pair is lower than the power threshold;

Among the results of detecting the power value of the reference signal on the original beam pair multiple times, the number of times the power value of the reference signal on the original beam is lower than the threshold is greater than the threshold.

Among the multiple measurement results, the reference signal power values of multiple continuous measurements may be lower than the threshold, or the reference signal power values of discontinuous multiple measurements may be lower than the threshold.

When the power value of the reference signal on the original beam pair satisfies the above switching conditions, the user equipment can determine the beam pair information, where there are two types of beam pair information:

In the first type, the beam pair information includes the beam pair information corresponding to the original beam pair:

At this time, the user equipment cannot determine a candidate target beam pair, and the user equipment 10 determines that there is no suitable beam pair that can be used as a candidate target beam pair.

In the second type, the beam pair information includes beam pair information corresponding to the original beam pair and the candidate target beam pair.

At this time, the user equipment can determine a candidate target beam pair, and the user equipment determines that there is a suitable beam pair that can be used as a candidate target beam pair.

Alternative target beam pairs may be some or all of the following beam pairs:

A standby beam pair corresponding to the user equipment;

The reference signal power value is larger than the threshold beam pair.

The user equipment may use the spare beam pair corresponding to the user equipment as the candidate target beam pair; the user equipment may use a beam pair whose reference signal power value is greater than a threshold as the candidate target beam pair; The user equipment may use the spare beam pair corresponding to the user equipment and the beam pair whose reference signal power value is greater than a threshold as the candidate target beam pair.

It should be noted that there may be one or more candidate target beam pairs.

After determining the beam pair information, the user equipment reports the beam pair information to the macro base station, so that the macro base station determines a target beam pair according to the beam pair information.

The beam pair information includes, but is not limited to, transmitting unit information corresponding to the beam pair, beam pair indication information, and a power value of a reference signal on the beam pair. The form of reporting information may be a signaling containing N fields, and each field is written with beam pair information corresponding to a beam pair.

Since the signaling is sent when the power value of the reference signal between the user equipment and the original transmitting unit satisfies the handover condition, that is, when there is a blocking phenomenon, the signaling can be called BI signaling.

It should be noted that when the macro base station is a low-frequency macro base station, the communication between the user equipment and the macro base station is a low-frequency communication, which is less affected by the blocking phenomenon, that is, the beam pair information can be reported to the macro base station relatively smoothly. .

Since high-frequency communication has many advantages, the direct communication with the user equipment can be a high-frequency transmitting unit, that is, the original transmitting unit is a high-frequency transmitting unit, and the candidate target transmitting unit corresponding to the candidate target beam pair is a high-frequency transmitting unit. frequency transmitter unit.

According to the beam pair information, the macro base station will make corresponding processing.

In the first type, the beam pair information includes the beam pair information corresponding to the original beam pair:

Since there is no beam pair information corresponding to the candidate target beam pair in the information reported at this time, the macro base station may determine that there is no suitable beam pair as the candidate target beam pair;

If the selected target beam pair reference signal power value is lower than the target beam pair reference signal power value threshold, the candidate target beam pair is not determined as the target beam pair, and the user equipment is notified that switching cannot be performed. If the power value is higher than the target beam pair reference signal power value threshold, the candidate target beam pair is determined as the target beam pair.

The macro base station transmits beam pair information corresponding to the original beam pair and the target beam pair to the original transmitting unit corresponding to the original beam pair and the target transmitting unit corresponding to the target beam, so that the original transmitting unit and the target transmitting unit switch the beam pair .
