Description

Wireless communication method and device and communication equipment

Technical Field

The present application relates to the field of communications, and more particularly, to a method and apparatus for wireless communication and a communication device.

Background

The basis of wireless communication is spectrum resources, which can be divided into licensed and unlicensed spectrum. Licensed spectrum refers to spectrum resources that are licensed for use by a particular operator, while unlicensed spectrum refers to spectrum resources that may be used by any operator or terminal device. Before devices communicate using the unlicensed spectrum, channel idle detection, which may also be referred to as Listen Before Talk (LBT), is required, and when a channel is detected to be in an idle state, the unlicensed spectrum may be used for communication, so that mutual interference between the devices may be avoided. Transmitting signals through a beam can concentrate signal energy in one direction with very little interference in the other direction. The transmission of signals over unlicensed spectrum using beams has become a focus of research by those skilled in the art.

It should be understood that the present application is not limited to the particular form of the terminal device.

S210, the network equipment sends first information to the terminal equipment.

The terminal device receives the first information sent by the network device, where the first information is Radio Resource Control (RRC) signaling, and the first information may also be referred to as configuration information.

S220, the terminal device measures one or more beams.

The one or more beams are unlicensed frequency bands, and the terminal device measures the one or more beams to determine loading conditions of the one or more beams.

In one embodiment, the first information includes a first information element indicating the one or more beams.

Optionally, the first information element includes an identifier of each of the one or more beams, and the terminal device determines the beam to be measured according to the identifier of each of the one or more beams.

In another embodiment, the terminal device measures all beams, or the terminal device measures some beams based on internal implementation.

For example, in the case where the terminal device detects that the identification of the beam to be measured is not included in the first information, all beams are measured or part of beams are measured based on internal implementation.

And S230, the terminal equipment determines K wave beams according to the first information.

In one embodiment, the first information may include a second information element, and the terminal device determines the K beams from the one or more beams according to the second information element, where K is an integer greater than 0.

By way of example and not limitation, the second information element is used to indicate the first threshold value and/or the second threshold value. Wherein, the first threshold is a threshold of a Received Signal Strength Indicator (RSSI), and the load of the beam is lighter when the RSSI of the beam is smaller than or equal to the first threshold; the method includes that the load of the beam is heavy when the RSSI value of the beam is greater than or equal to a first threshold value, where the RSSI value is equal to the first threshold value, which may be the case that the load of the beam is light, or the case that the load of the beam is heavy, and which may be determined according to a specific implementation manner, and the application is not limited to this. The second threshold is a threshold of a Channel Occupancy (CO). CO is the proportion of all measurement samples taken during a measurement period for which the RSSI measurement is above a threshold. Under the condition that the value of the CO of the beam is smaller than or equal to the first threshold value, the load of the beam is lighter; the load of the beam is heavy when the value of CO of the beam is greater than or equal to the first threshold, where the condition that the value of CO is equal to the first threshold may be a condition that the load of the beam is light, or may be a condition that the load of the beam is heavy, and the determination may be made according to a specific implementation manner, which is not limited in this application.

It should be noted that, when the second cell is used to indicate the first threshold and the second threshold, one second cell in the first information may indicate the two thresholds, or the first information may include two second cells, one second cell is used to indicate the first threshold, and the other second cell is used to indicate the second threshold.

In another embodiment, the first information may include a second information element and a third information element, and the terminal device determines the K beams from the one or more beams according to the second information element and the third information element.

By way of example and not limitation, the third information element is used to indicate the first number. The first number is used for the terminal device to determine the number of the reported beams, that is, the first number is used for the terminal device to determine the number of the beam identifiers included in the second information.

In this application, the first cell, the second cell and the third cell may be included in the same cell (e.g., a fifth cell), that is, the first information may include a fifth cell including the first cell, the second cell and the third cell, or the first information itself is the fifth cell, which is not limited in this application.

The manner in which the terminal device determines the K beams includes, but is not limited to, one or more of the following:

mode 1

The second cell comprises a first threshold value, and the terminal equipment reports the beam with the RSSI measurement value less than or equal to the first threshold value to the network equipment. Specifically, the terminal device measures the RSSI values of the one or more beams and determines the beams for which the measured RSSI values are less than or equal to the first threshold value, i.e., the less loaded beams.

When the first information includes the first number, where the terminal device determines K beams in the beams whose RSSI measurement value is less than or equal to the first threshold value, where K is less than or equal to the first number, that is, the first number is a maximum value of the number of beams reported by the terminal device, or the first number is a maximum value of the number of beam identifiers included in the second information. If the number of beams smaller than or equal to the first threshold value is greater than or equal to the first number, K is equal to the first number, and if the number of beams smaller than or equal to the first threshold value is smaller than the first number, K is smaller than the first number, that is, K is the number of beams for which all measured RSSI measurements are smaller than or equal to the first threshold value.

When the first information does not include the first number, the terminal device may report all beams in which the RSSI measurement value is smaller than or equal to the first threshold, that is, the second information includes an identifier of each beam in all beams in which the RSSI measurement value is smaller than or equal to the first threshold, that is, the one or more beams include beams in which the K RSSI measurement values are smaller than or equal to the first threshold, and the terminal device reports the identifiers of the K beams to the network device. Or randomly selecting part of beams for reporting from beams with the RSSI measurement value less than or equal to a first threshold value based on the implementation of the terminal equipment, wherein the K beams are beams with K RSSI measurement values less than or equal to the first threshold value determined by the terminal equipment based on the internal implementation.

After the terminal device determines to report the K beams, the terminal device generates second information, where the second information includes an identifier of each beam of the K beams, and the terminal device sends the second information to the network device. That is to say, the terminal device notifies the network device of the beam with a lighter load determined according to the RSSI value of the beam through the second information, so that the network device selects the beam of the unlicensed frequency band for communication, which can reduce communication collision on the unlicensed frequency spectrum and improve the utilization efficiency of the unlicensed frequency spectrum.

For example, the first information includes identifiers of 8 beams and a first threshold value, and the terminal device measures an RSSI value of each beam identified by the 8 beam identifiers, where RSSI values of 3 beams are less than or equal to the first threshold value.

In the case that the first information does not include the first number, the terminal device may report all beams in which the RSSI measurement value is smaller than or equal to the first threshold, that is, the second information includes identifiers of 3 beams in which the RSSI measurement value is smaller than or equal to the first threshold.

If the first number is 2, that is, the terminal device reports the identifiers of the beams with the maximum number of 2 RSSI measurements smaller than or equal to the first threshold value, and since the number of the beams with the measured RSSI measurements smaller than or equal to the first threshold value is 3 and greater than 2, the terminal device reports 2 beams with the measured RSSI measurements smaller than or equal to the first threshold value, where the reported 2 beams may be two beams with the minimum RSSI measurement, may be two beams with the minimum identifiers or the maximum identifiers among the 3 beams, or may be implemented by the terminal device to select 2 beams among the 3 beams, but the application is not limited thereto.

In the first information, the identities of the beams may be arranged in order from small to large or from large to small. The identities of the beams may also be ranked in order from large to small, i.e., the load is ranked from heavy to light, according to the RSSI measurements of the beams. The identities of the beams may also be ranked in order of small to large RSSI measurements for the beams, i.e., in order of light to heavy load. The identification of the beams may also be arranged by the implementation of the terminal device, but the application is not limited thereto.

If the first number is 4, the terminal device determines that the number of the beams with the measured value of the RSSI less than or equal to the first threshold is at most reported, and since the number of the beams with the measured value of the RSSI less than or equal to the first threshold obtained by measurement is 3 and less than 4, the terminal device reports the 3 beams with the measured value of the RSSI less than or equal to the first threshold. The terminal device transmits second information including the 3 beam identifications to the network device. For example, the 3 beam identifiers are 3, 5, and 6, wherein the beam identifiers may be arranged in the order of the beam identifiers from small to large or from large to small. The identities of the beams may also be ranked in order from large to small, i.e., the load is ranked from heavy to light, according to the RSSI measurements of the beams. The identities of the beams may also be ranked in order of small to large RSSI measurements for the beams, i.e., in order of light to heavy load. The identification of the beams may also be arranged by the implementation of the terminal device, but the application is not limited thereto.

For example, the beam identifiers are arranged in the order of the RSSI measurement values of the beams from small to large, and the beam identifiers in the second information are 5, 3, and 6, but the present application is not limited thereto. Optionally, the terminal device may further generate a first list, where the first list includes identifiers of beams that satisfy a reporting condition, the reporting condition is that the number of beams whose RSSI measurement value is less than or equal to a first threshold value and/or the number of reported beam identifiers is not greater than a first number, and the second information may include the first list, for example, as shown in table 1:

TABLE 1

Optionally, the second information may further include a measured RSSI value of the reported beam, where the measured RSSI value of the beam corresponds to the identifier of each beam included in the second information.

Mode 2

The second cell comprises a second threshold value, and the terminal equipment reports the beam with the CO measurement value less than or equal to the second threshold value to the network equipment. Specifically, the terminal device measures the value of CO for the one or more beams and determines the beams for which the measured value of CO is less than or equal to the second threshold value, i.e. the less loaded beams.

When the first information includes the first number, the terminal device determines K beams from the beams whose CO measurement value is less than or equal to the second threshold, where K is less than or equal to the first number, that is, the first number is a maximum value of the number of beams reported by the terminal device, or the first number is a maximum value of the number of beam identifiers included in the second information. K is equal to the first number if the number of beams smaller than or equal to the second threshold is greater than or equal to the first number, and is smaller than the first number if the number of beams smaller than or equal to the second threshold is smaller than the first number, i.e. K is the number of beams for which all measured values of CO are smaller than or equal to the second threshold.

When the first information does not include the first number, the terminal device may report all beams with the CO measurement value less than or equal to the second threshold, that is, the second information includes the identifier of each beam in all beams with the CO measurement value less than or equal to the second threshold, that is, the one or more beams include beams with the K CO measurement values less than or equal to the second threshold, and the terminal device reports the identifiers of the K beams to the network device. Or randomly selecting part of beams for reporting based on beams of which the measured value of the realized CO of the terminal equipment is less than or equal to the second threshold value, wherein the K beams are beams of which the measured values of the K CO determined by the terminal equipment based on internal realization are less than or equal to the second threshold value.

After the terminal device determines to report the K beams, the terminal device generates second information, where the second information includes an identifier of each beam of the K beams, and the terminal device sends the second information to the network device. That is to say, the terminal device notifies the network device of the beam with a lighter load determined according to the measured value of the CO of the beam through the second information, so that the network device selects the beam of the unlicensed frequency band for communication, which can reduce communication collision on the unlicensed frequency spectrum and improve the utilization efficiency of the unlicensed frequency spectrum.

For example, the first information includes identifiers of 10 beams and a second threshold, and the terminal device measures a measured value of CO of each beam identified by the 10 beam identifiers, where the measured value of CO of 4 beams is less than or equal to the second threshold.

In the case that the first information does not include the first number, the terminal device may report all beams whose CO measurement values are smaller than or equal to the second threshold, that is, the second information includes the identities of 4 beams whose CO measurement values are smaller than or equal to the second threshold.

If the first number is 3, that is, the terminal device reports the identifiers of the beams with the maximum number of reported 3 CO measurement values smaller than or equal to the second threshold, and since the number of the beams with the measured CO measurement values smaller than or equal to the second threshold is 4 and greater than 3, the terminal device reports 3 beams of the 4 beams with the measured CO measurement values smaller than or equal to the second threshold, where the reported 3 beams may be the 3 beams with the minimum CO measurement values, may be the 3 beams with the minimum or maximum identifiers among the 4 beams, or may be implemented by the terminal device to select 3 beams of the 4 beams, but the application is not limited thereto. If the first number is 4, that is, the terminal device reports the identifiers of the beams of which the measured values of the CO are less than or equal to the second threshold at most, since the number of the beams of which the measured values of the CO are less than or equal to the second threshold obtained by measurement is 4 and is equal to 4, the terminal device reports the 4 beams of which the measured values of the CO are less than or equal to the second threshold. And the terminal equipment determines to report the 4 wave beams and sends second information comprising the 4 wave beam identifiers to the network equipment. For example the 4 beams are identified as 1, 3, 6, 7.

In the first information, the identities of the beams may be arranged in order from small to large or from large to small. The identities of the beams may also be arranged in order of the measured values of the CO of the beams from large to small, i.e. the load is arranged in order of heavy to light. The identities of the beams may also be arranged in order from small to large measured values of CO of the beams, that is, the load is arranged in order from light to heavy, and the identities of the beams may also be arranged by the implementation of the terminal device, but the present application is not limited thereto.

For example, the identifiers of the beams are arranged in the order of the measured values of the CO of the beams from small to large, and the identifiers of the beams in the second information are arranged in the order of 3, 6, 1, and 7, but the present application is not limited thereto.

Optionally, the terminal device may further generate a second list, where the second list includes identifiers of beams that satisfy a reporting condition, and the reporting condition is that the number of beams whose measured value of CO is less than or equal to a second threshold and/or the number of reported beam identifiers is not greater than the first number, and the second information may include the second list, for example, as shown in table 2:

TABLE 2

That is, when a beam satisfies that the measured value of RSSI is less than or equal to the first threshold, the terminal device reports the beam no matter whether the measured value of CO is greater than, equal to, or less than the second threshold. Or, when a beam satisfies that the measured value of CO is less than or equal to the second threshold, the terminal device reports the beam no matter whether the measured value of RSSI is greater than, equal to, or less than the first threshold.

When the first information includes the first number, the terminal device determines K beams in the beams that satisfy that the measured value of the RSSI is less than or equal to the first threshold or that satisfy that the measured value of the CO is less than or equal to the second threshold, where K is less than or equal to the first number, and the specific implementation may refer to the description in the mode 1, and for brevity, details are not repeated here. If the measured value satisfying RSSI is less than or equal to the first threshold value, or the number of beams satisfying the measured value of CO is less than or equal to the second threshold value is greater than or equal to the first number, K is equal to the first number, if the measured value satisfying RSSI is less than or equal to the first threshold value, or the number of beams satisfying the measured value of CO is less than or equal to the second threshold value is less than the first number, K is less than the first number, that is, K is the number of beams in which all the measured values of RSSI are less than or equal to the first threshold value, or the measured value of CO is less than or equal to the second threshold value.

When the first information does not include the first number, the terminal device may report all beams that satisfy the RSSI measurement value less than or equal to the first threshold, or that satisfy the CO measurement value less than or equal to the second threshold, that is, the second information includes the RSSI measurement value less than or equal to the first threshold, or the CO measurement value less than or equal to the second threshold, that is, the one or more beams include K beams that satisfy the RSSI measurement value less than or equal to the first threshold, or that satisfy the CO measurement value less than or equal to the second threshold. Or randomly selecting part of beams to report from beams which meet the conditions that the measured value of RSSI is less than or equal to a first threshold value or the measured value of CO is less than or equal to a second threshold value based on the implementation of the terminal equipment, wherein the K beams are determined by the terminal equipment based on the internal implementation that K measured values which meet the conditions that RSSI is less than or equal to the first threshold value or the measured value of CO is less than or equal to the second threshold value.

The terminal device informs the network device of the beam with lighter load through the second information, so that the network device can select the beam of the unlicensed frequency band for communication, communication conflict on the unlicensed frequency spectrum can be reduced, and the utilization efficiency of the unlicensed frequency spectrum is improved. For example, the first information includes identities of 10 beams, a first threshold value and a second threshold value, and the terminal device measures RSSI measurement values and CO measurement values of 10 beams, where the RSSI measurement values of 3 beams are less than or equal to the first threshold value, for example, the CO measurement values of beams 1, 3, 6, 1 are less than or equal to the second threshold value, for example, beam 1, where beam 1 satisfies both that the RSSI measurement value is less than or equal to the first threshold value and that the CO measurement value is less than or equal to the second threshold value.

In one embodiment, the terminal device may also send, to the network device, identifiers including 4 beams, including identifiers 1, 3, and 6 of beams satisfying that the RSSI measurement value is less than or equal to the first threshold value, and identifier 1 of a beam satisfying that the CO measurement value is less than or equal to the second threshold value.

In another embodiment, the terminal device may send the second information including the identifiers of the 3 beams, that is, including the beam identifiers 1, 3, and 6, to the network device.

In the first information, the identities of the beams may be arranged in order from small to large or from large to small. The identities of the beams may also be ranked in order from big to small, i.e., from heavy to light, based on the RSSI and/or CO measurements of the beams. The identities of the beams may also be ranked in order of small to large RSSI and/or CO measurements, i.e., load from light to heavy. The identification of the beams may also be arranged by the implementation of the terminal device, but the application is not limited thereto.

Or, based on the implementation of the terminal device, randomly selecting N beams for reporting from beams with RSSI measurement values less than or equal to a first threshold, and randomly selecting M beams for reporting from beams with CO measurement values less than or equal to a second threshold.

For example, the first information includes identifiers of 10 beams, a first threshold value and a second threshold value, and the terminal device measures RSSI values and CO values of each beam identified by the 10 beam identifiers, where the measured value including RSSI of 3 beams is less than or equal to the first threshold value, such as beams 1, 4, and 5, and the measured value including CO of 2 beams is less than or equal to the second threshold value, such as beams 1 and 3.

In an embodiment, when the first information does not include the first number and the second number, the terminal device may report all beams in which the RSSI measurement value is smaller than or equal to the first threshold, that is, the second information includes identifiers 1, 4, and 5 of 3 beams in which the RSSI measurement value is smaller than or equal to the first threshold. And the terminal device also reports all beams with the CO measurement value less than or equal to the second threshold, that is, the second information further includes identifiers 1 and 3 of 2 beams with the CO measurement value less than or equal to the second threshold, and the second information includes 5 beam identifiers in total, that is, K is 5.

In another embodiment, when the first information includes the first number, if the first number is 2, that is, the terminal device reports the identifiers of the beams whose measured values of the at most 2 RSSI are less than or equal to the first threshold, because the number of the beams whose measured values of the RSSI are less than or equal to the first threshold is 3 and is greater than 2, the terminal device reports 2 beams among the 3 beams whose measured values of the RSSI are less than or equal to the first threshold, the 2 reported beams may be two beams whose measured values of the RSSI are minimum, may be two beams whose identifiers are minimum or maximum among the 3 beams, or may be implemented by the terminal device to select 2 beams among the 3 beams, but the application is not limited thereto. And the terminal equipment reports the identifiers of the beams of which the measured values of the 2 COs are less than or equal to the second threshold value at most, and the terminal equipment reports the 2 beams of which the measured values of the COs are less than or equal to the second threshold value because the number of the beams of which the measured values of the COs are less than or equal to the second threshold value is 2 and is equal to 2.

For example, the terminal device determines 2 beams, beams 1 and 4, for which the RSSI measurement value is less than or equal to the first threshold value and 2 beams, beams 1 and 3, for which the CO measurement value is less than or equal to the second threshold value. The second information comprises the identities 1, 4 of the beams for which the measured value of RSSI is less than or equal to the first threshold value, and the second information further comprises the identities 1, 3 of the beams for which the measured value of CO is less than or equal to the second threshold value, the second information comprising a total of 4 beam identities.

In another embodiment, when the first information includes the first number and the second number, if the first number is 2, that is, the terminal device reports the identifiers of the beams with the maximum number of 2 RSSI measurements smaller than or equal to the first threshold, because the number of the beams with the measured RSSI measurements smaller than or equal to the first threshold is 3 and greater than 2, the terminal device reports 2 beams of the 3 beams with the measured RSSI measurements smaller than or equal to the first threshold, where the 2 reported beams may be the 2 beams with the minimum RSSI measurement, or may be the 2 beams with the minimum or maximum identifiers among the 3 beams, or the terminal device may select the 2 beams of the 3 beams, but the present application is not limited thereto. And the second number is 3, the terminal device reports at most, the number of the beams with the measured values of 3 CO less than or equal to the second threshold is 2, and the number of the beams with the measured values of CO less than or equal to the second threshold is less than 3, so that the terminal device reports the 2 beams with the measured values of CO less than or equal to the second threshold.

For example, the terminal device determines 2 beams, beams 1 and 4, for which the RSSI measurement value is less than or equal to the first threshold value and 2 beams, beams 1 and 3, for which the CO measurement value is less than or equal to the second threshold value. The second information includes the identifiers 1 and 4 of the beams whose RSSI measurement value is less than or equal to the first threshold value, where the identifiers of the beams 1 and 4 may be arranged from large to small or from small to large according to the RSSI measurement value, or may be arranged from large to small or from small to large according to the identifiers of the beams, or may be arranged by the implementation of the terminal device, which is not limited in this application. The second information further includes identifiers 1 and 3 of beams whose measured values of CO are less than or equal to the second threshold, where the identifiers of the beams 1 and 3 may be arranged from large to small or from small to large of the measured values of CO, or may be arranged from large to small or from small to large of the identifiers of beams, and the identifiers are arranged by the implementation of the terminal device, which is not limited in this application. The second information includes 4 beam identifications in total.

Alternatively, the terminal device may generate two lists, where one list includes the identities of the beams whose measured values of 2 RSSI are less than or equal to the first threshold value, as shown in table 4, and the other list includes the identities of the beams whose measured values of 2 CO are less than or equal to the second threshold value, as shown in table 5.

Optionally, the second information may further carry a RSSI measurement value and a CO measurement value of the reported beam, where the RSSI measurement value of the beam corresponds to the identifier of the beam in the second information, where the RSSI measurement value is smaller than or equal to the first threshold, and the CO measurement value of the beam corresponds to the identifier of the beam in the second information, where the CO measurement value is smaller than or equal to the second threshold.

In the above modes 1 to 5, a mode in which the terminal device reports K beams with a light load to the network device is described, and in the following modes 6 to 10, a mode in which the terminal device reports K beams with a heavy load to the network device is described.

Mode 6

The second cell comprises a first threshold value, and the terminal equipment reports the beam with the RSSI measurement value being greater than or equal to the first threshold value to the network equipment. Specifically, the terminal device measures the RSSI values of the one or more beams and determines the beams for which the measured RSSI values are greater than or equal to the first threshold value, i.e., the beams with heavier load.

When the first information includes the first number, the terminal device determines K beams from the beams in which the RSSI measurement value is greater than or equal to the first threshold, where K is less than or equal to the first number, that is, the first number is a maximum value of the number of beams reported by the terminal device, or the first number is a maximum value of the number of beam identifiers included in the second information. If the number of beams greater than or equal to the first threshold value is greater than or equal to the first number, K is equal to the first number, and if the number of beams greater than or equal to the first threshold value is less than the first number, K is less than the first number, that is, K is the number of beams for which all measured RSSI measurements are greater than or equal to the first threshold value.

When the first information does not include the first number, the terminal device may report all beams in which the RSSI measurement value is greater than or equal to the first threshold, that is, the second information includes an identifier of each beam in all beams in which the RSSI measurement value is greater than or equal to the first threshold, that is, the one or more beams include beams in which the K RSSI measurement values are greater than or equal to the first threshold, and the terminal device reports the identifiers of the K beams to the network device. Or randomly selecting part of beams for reporting from beams with the RSSI measurement value being greater than or equal to a first threshold value based on the implementation of the terminal equipment, wherein the K beams are beams with the K RSSI measurement values being greater than or equal to the first threshold value and determined by the terminal equipment based on the internal implementation.

After the terminal device determines to report the K beams, the terminal device generates second information, where the second information includes an identifier of each beam of the K beams, and the terminal device sends the second information to the network device. That is to say, the terminal device notifies the network device of the beam with the heavier load determined according to the measured value of the RSSI of the beam through the second information, so that the network device selects the beam of the unlicensed frequency band for communication, which can reduce communication collision on the unlicensed frequency spectrum and improve the utilization efficiency of the unlicensed frequency spectrum.

For example, the first information includes identifiers of 5 beams and a first threshold value, and the terminal device measures an RSSI value of each beam identified by the 5 beam identifiers, where the RSSI measured value of 4 beams is greater than or equal to the first threshold value.

In the case that the first information does not include the first number, the terminal device may report all beams in which the RSSI measurement value is greater than or equal to the first threshold, that is, the second information includes the identifiers of the 4 beams in which the RSSI measurement value is greater than or equal to the first threshold.

If the first number is 4, that is, the terminal device reports the identifiers of the beams of which the measured values of the 4 RSSI are greater than or equal to the first threshold at most, since the number of the beams of which the measured values of the RSSI are greater than or equal to the first threshold is 4 and is equal to 4, the terminal device reports the 4 beams of which the measured values of the RSSI are greater than or equal to the first threshold. And the terminal equipment determines to report the 4 wave beams and sends second information comprising the 4 wave beam identifiers to the network equipment. Such as the 4 beams are identified as 1, 3, 5, 6.

In the first information, the identities of the beams may be arranged in order from small to large or from large to small. The identities of the beams may also be ranked in order from large to small, i.e., the load is ranked from heavy to light, according to the RSSI measurements of the beams. The identities of the beams may also be ranked in order of small to large RSSI measurements for the beams, i.e., in order of light to heavy load. The identification of the beams may also be arranged by the implementation of the terminal device, but the application is not limited thereto. For example, the identifiers of the beams are arranged in order of the RSSI measurement values of the beams from small to large, and the second information includes identifiers of the beams 1, 5, 3, and 6, but the present application is not limited thereto. Optionally, the terminal device may further generate a list, for example, as shown in table 6, where the list includes identifiers of beams that meet the reporting condition, and the reporting condition is that the number of beams whose RSSI measurement value is greater than or equal to the first threshold and/or the number of reported beam identifiers is not greater than the first number, and the second information may include the list.

Specifically, the terminal device measures the value of CO of the one or more beams and determines the beam for which the measured value of CO is greater than or equal to the second threshold value, i.e., the beam with the heavier load.

When the first information includes the first number, the terminal device determines K beams from the beams whose CO measurement value is greater than or equal to the second threshold, where K is less than or equal to the first number, that is, the first number is a maximum value of the number of beams reported by the terminal device, or the first number is a maximum value of the number of beam identifiers included in the second information. K is equal to the first number if the number of beams greater than or equal to the second threshold is greater than or equal to the first number, and is less than the first number if the number of beams greater than or equal to the second threshold is less than the first number, i.e., K is the number of beams for which all measured values of CO are greater than or equal to the second threshold.

After the terminal device determines to report the K beams, the terminal device generates second information, where the second information includes an identifier of each beam of the K beams, and the terminal device sends the second information to the network device. That is to say, the terminal device notifies the network device of the beam with the heavier load determined according to the measured value of the CO of the beam through the second information, so that the network device selects the beam of the unlicensed frequency band for communication, which can reduce communication collision on the unlicensed frequency spectrum and improve the utilization efficiency of the unlicensed frequency spectrum.

For example, the first information includes identifiers of 10 beams and a second threshold value, and the terminal device measures a value of CO of each beam identified by the 10 beam identifiers, where the measured value of CO of 5 beams is greater than or equal to the second threshold value.

In the case that the first information does not include the first number, the terminal device may report all beams whose CO measurement values are greater than or equal to the second threshold, that is, the second information includes the identities of 5 beams whose CO measurement values are greater than or equal to the second threshold.

If the first number is 3, that is, the terminal device reports the identifiers of the beams with the maximum 3 CO measurement values greater than or equal to the second threshold, and since the number of the beams with the measured CO measurement values greater than or equal to the second threshold obtained by measurement is 5 and greater than 3, the terminal device reports 3 beams of the 5 beams with the measured CO measurement values greater than or equal to the second threshold, where the reported 3 beams may be the 3 beams with the maximum CO measurement value, may be the 3 beams with the minimum or the maximum identifiers of the 5 beams, or may be implemented by the terminal device to select 3 beams of the 5 beams, but the present application is not limited thereto. If the first number is 6, that is, the terminal device reports the identifiers of the beams of which the measured values of the CO are greater than or equal to the second threshold at most, since the number of the beams of which the measured values of the CO are greater than or equal to the second threshold is 5 and less than 6, the terminal device reports the 5 beams of which the measured values of the CO are greater than or equal to the second threshold.

The identities of the beams may also be arranged in order of the measured values of the CO of the beams from large to small, i.e. the load is arranged in order of heavy to light. The identities of the beams may also be arranged in an order from small to large measured values of CO of the beams, that is, the load is arranged in an order from light to heavy, and the identities of the beams may also be arranged by the implementation of the terminal device, but the application is not limited thereto.

For example, the identifiers of the beams are arranged in the order from small to large, such as the first number is 3, and the identifiers of the beams in the second information are ordered as 3, 6, and 7, but the application is not limited thereto.

Optionally, the terminal device may further generate a list, the second information may include the list, and the manner of generating the list may be similar to the manner described above, and for brevity, details are not repeated here.

For example, the beams are sorted in order of light to heavy load, with the identification of the most lightly loaded beam ranked in the first position, the identification of the second least loaded beam ranked in the second position, and so on, and the most heavily loaded identification ranked in the last position.

S350, the first network device sends a first message to the second network device, where the first message includes a load of a cell of the second network device. As an example and not by way of limitation, the first network device may extract the value of the cell load in the third information to be carried in the first message forwarded to the second network device.

By way of example and not limitation, the first message may be a cell handover request message sent by the first network device to the second network device, the cell handover request message requesting handover of the terminal device to a cell of the second network device.

Optionally, the first message may further include identifiers of beams used for calculating cell loads, and/or values of loads of beams corresponding to the identifiers (e.g., a measurement value of RSSI and/or a measurement value of CO), so that the second network device can more accurately determine the load condition of each beam. By way of example and not limitation, the first network device may extract the identifier of the beam in the third information, and/or the value of the load of the beam corresponding to each identifier is carried in the first message and forwarded to the second network device.

And in the case that the second network device determines to handover the terminal device to the cell of the second network device, the second network device allocates a dedicated random access resource to the terminal device according to the value of the load of the cell (e.g., calculating the identifier of the beam loaded by the cell, and/or the value of the load of the beam corresponding to each identifier (e.g., the measured value of RSSI and/or the measured value of CO) included in the first message, where the dedicated random access resource is a dedicated random access resource on a beam with a lighter load.

According to the scheme of the application, the terminal device determines the cell load and/or the beam load of the second network device according to the configuration information of the first network device, and sends the cell load and/or the beam load to the second network device through the first network device, and the cell load and/or the beam load are used as a reference for whether the second network device switches the terminal device to the cell of the second network device, so that the utilization efficiency of the unlicensed spectrum is improved. The terminal device may estimate the load of the cell of the second network device from an average of the measurements of RSSI and/or an average of the measurements of CO for the plurality of beams.
