Specifically, in order to meet the access requirement of the terminal to the high-frequency station in the high-frequency communication mode in the prior art, even if no terminal exists in each transmission beam direction, a continuous or periodic transmission beam identification signal is required for the terminal entering the range subsequently to serve as a measurement basis for accessing the high-frequency station.

It should be noted that the first network device BS supports high frequency communication capability, which includes two cases, that is, the first network device BS has the capability of high frequency communication and low frequency communication; the second co-sited low frequency BS and the high frequency BS are collectively referred to as a first network device, and the low frequency BS does not have high frequency communication capability at this time, but can be connected to the high frequency BS through a wired link or any other link form due to co-siting. The embodiments of the present invention are described by taking the first case as an example, and for the second case, only the interaction process between the low frequency BS and the high frequency BS is added, and in the co-sited case, it can be considered as an internal implementation of the first network device, and thus there is no substantial difference from the first case in practice.
The following embodiments of the present invention are specifically illustrated in the following by taking an application in an LTE network as an example, and accordingly, the first network device is specifically an evolved Node B (eNB), and the embodiments of the present invention may also be applied in other cellular Communication networks, such as a Global System for mobile Communication (GSM), a Universal Mobile Telecommunications System (UMTS), a Code division multiple Access 95(Code division multiple Access 95, CDMA95)/CDMA2000, and a Long Term Evolution Advanced (LTE-a) network.
The following specific embodiments of the present invention may be combined, and the same or similar concepts or processes may not be described in detail in some embodiments.
Fig. 1 is a flowchart of a data communication method according to an embodiment of the present invention. The data communication method provided by this embodiment is suitable for the case of performing high frequency communication, and the method may be performed by a network device, where the network device is usually implemented in a hardware and software manner, and the network device performing the method provided by this embodiment may be, for example, a base station. As shown in fig. 1, the method of this embodiment may include:
s110, the first network device sends a first beam identification configuration message to the second network device through the low frequency communication link, where the first beam identification configuration message is used to instruct the second network device to measure a beam of a current transmission beam identification signal, and selects a first beam whose first measurement value satisfies a first threshold, where the current transmission beam is a part or all of beams of the first network device.
The beam identification signal in this embodiment is transmitted by the first network device in a plurality of or each beam direction of the high frequency band, so that the second network device can identify the beam sequence after measuring the transmitted beam. In this embodiment, the transmission beam of the first network device on the high frequency band is not always on, and is usually in a transmission stop state, and the beam identification signal transmitted by a part of or all beams of the first terminal is turned on only when triggered by the high frequency communication service. Specifically, the factors triggering the high frequency communication service include one or more of the following: the second network equipment initiates a high-frequency coverage request to the first network node through the low-frequency communication link; the second network device initiates a service request adapted to be provided in the high frequency network; the first network device is expected to switch the second network device to the high-frequency network to perform load shunting for the low-frequency network; the second network device needs to reselect a transmit beam appropriate for the first network device.
As shown in fig. 2, a schematic view of an application scenario provided in the embodiment shown in fig. 1 is shown, where in this embodiment, a first network device is an eNB, and a second network device is a UE, and a specific manner of triggering high-frequency network communication in this embodiment is further included before S110: s100, a first network device receives a high-frequency coverage request or a service request sent by a second network device through a low-frequency communication link, wherein the high-frequency coverage request or the service request comprises an identifier of the second network device; s101, the first network equipment starts a part of or all wave beam transmission wave beam identification signals according to a high-frequency covering request or a service request. In this embodiment, the high frequency coverage request and the service request are both sent to the eNB by the UE through the low frequency communication link, the high frequency coverage request may directly request to establish the high frequency communication link with the eNB to meet the transmission requirement of a large data volume, and the service content in the service request may also instruct the first network device to automatically start the high frequency communication establishment procedure to adapt to the service data volume requested by the service request.
In a specific implementation, the location information is a high-frequency coverage request or optional content in the service request, and if the high-frequency coverage request received by the first network device or the service request in S100 further includes location information of the second network device, S101 may be replaced with: the first network equipment determines a part of beams in the direction of the second network equipment according to the position information and starts a part of beam transmitting beam identification signals; if the high-frequency coverage request received by the first network device or the service request in S100 does not include the location information of the second network device, S101 may be replaced with: and the first network equipment starts all beam transmitting beam identification signals according to the high-frequency coverage request or the service request.
For example, if the second network device sends a high frequency overlay request, the content of the high frequency overlay request may further include: the high frequency coverage request includes, for example, specific contents in the high frequency coverage request, which are illustrated in table 1 below, one or more of a high frequency band frequency range supported by the UE, an operating frequency point, a bandwidth, current service information of the UE, and parameters used for the eNB to establish the high frequency communication link, including, for example, a type of service expected to be transmitted on the high frequency communication link, a data amount to be transmitted, and a high frequency bandwidth requirement.
TABLE 1
| Identity of UE | 00000100 |
| Location information of UE | East longitude 30 degree, north latitude 56 degree |
| High frequency band range supported by UE | 38GHz-41GHz |
| Working frequency point supported by UE (center frequency) | 38.5GHz、39.5GHz、40.5GHz |
| Bandwidth supported by UE | 1GHz |
Specifically, the frequency of the transmit beam turned on by the first network device is within the high frequency band supported by the second network device. For example, the eNB determines, according to the frequency range, the working frequency point and the bandwidth information supported by the UE, that the configured high frequency band is 39GHz-40GHz, and determines, according to the location information of the UE, to turn on a partial beam transmission beam identification signal of the location where the UE is located, where the index information of the partial beam is: 0001. 0010, 0011, 0100 and 0101.
The first beam identification configuration message in this embodiment is also sent by the first network device on the established low-frequency communication link, and the beam identification configuration message includes index information of the current transmission beam and resource information occupied by the transmission beam identification signal, and is specifically used to instruct the second network device to measure the current transmission beam according to a resource position indicated by the resource information, select a first beam of which a first measurement value satisfies a first threshold, and acquire index information corresponding to the first beam according to the index information.
It should be noted that, the first beam identification configuration message further includes one or more of the following information: the working frequency point and the bandwidth of the current transmission beam, for example, the high-frequency working frequency point is 39.5GHz, the bandwidth is 1GHz, and the resource set and the transmission cycle of the beam identification signal, where the resource information and the resource set generally include time domain resources, frequency domain resources, and sequence resources. Specifically, the time domain resources include at least one of: orthogonal Frequency Division Multiplexing (OFDM) symbol, OFDM symbol group, subframe, wireless frame, micro frame, sending time interval and basic time domain resource unit, wherein the OFDM symbol group comprises at least one OFDM symbol, and the basic time domain resource unit allocates the minimum time unit of time domain resource for the first network equipment; the frequency domain resources comprise one or more of subcarriers, sub-bands, partial bandwidths and beam identification signal bandwidths; the sequence resource refers to a beam identification signal sequence employed by the beam identification signal.
For example, the first network device in this embodiment needs to provide the index information of the current transmission beam, for example, 0001, 0010, 0011, 0100, and 0101, the time domain resource and the frequency domain resource of the beam identification signal respectively corresponding to each transmission beam, and the specific sequence for transmitting each beam identification signal, and may indicate the time taken by the first network device to complete transmission of the beam identification signals of all beams at a time, that is, the transmission period of the beam identification signal.
S120, the first network device receives first beam selection information sent by the second network device, where the first beam selection information includes index information corresponding to the first beam.
It should be noted that the first beam selected by the second network device in each embodiment of the present invention may be a beam with the best service quality, that is, a beam with the largest first measurement value, or may be multiple beams with service quality meeting a preset value, that is, multiple beams with a first measurement value greater than the first threshold value, for example, 6 beams with a first measurement value greater than the first threshold value may be selected, and 4 of the beams may be selected as the first beam according to a preset rule; in this embodiment, 0100 is described by taking the index information corresponding to the first beam as an example.
And S130, the first network equipment establishes a high-frequency communication link with the second network equipment according to the first beam selection information, and closes part of beams of the current transmitted beam identification signal.
In this embodiment, the first network device receives index information corresponding to a first beam sent by the second network device, and may determine, through the index information, that an optimal transmission beam selected by the second network device is the first beam, so as to establish a high-frequency communication link with the second network device through the first beam, and further perform data communication with the second network device through the high-frequency communication link. In addition, after receiving the first beam selection information sent by the second network device, the first network device in this embodiment already determines that the first beam is a downlink beam for establishing a high-frequency communication connection with the second network device, that is, not all beams of the beam identification signal currently transmitted by the first network device may be downlink beams for performing high-frequency network communication with the second network device, so that the first network device may selectively close part of beams in the currently transmitted beam, where the closed beam is, for example, a beam having a larger position deviation from the second network device. It should be noted that the present embodiment does not limit the execution sequence of establishing the high-frequency communication link and closing the partial beams, and may be executed in parallel.
In a specific implementation of this embodiment, a specific manner for the first network device to close a part of beams in the current transmission beam may be, for example: in a first mode, the first network equipment closes all beams except the first beam; in a second mode, the first network equipment closes the first beam and all beams except the transmitting beam in a preset range adjacent to the first beam; and in the third mode, the first network equipment closes all the beams except the first beam and the second beam, and the second beam is a transmitting beam for the first network equipment and the third network equipment to carry out high-frequency network communication.
It should be noted that the first network device in this embodiment reserves transmission in some beam directions and stops transmission in other beam directions. First, the first beam selected in this embodiment is a transmission beam whose service quality satisfies a first threshold, where the first threshold is, for example, a minimum standard set for the service quality, and the rule of the first method is that the transmission beam whose service quality satisfies a preset requirement is reserved. Secondly, in order to ensure the mobility of the second network device, that is, when the second network device has a requirement for changing the optimal downlink beam due to movement, in order to avoid a situation that the second network device has a requirement for changing the optimal downlink beam but has no other downlink beam for selection, the first network device may use beams 0011 and 0101 adjacent to the first beam 0100 as candidate beams of the second network device, and reserve the 3 beams as downlink beams for high-frequency communication; at this time, the turned-off partial transmit beams follow the rule of the above-described manner two, that is, the transmit beams other than 0011, 0100, 0101 are turned off, that is, the transmit beams 0001 and 0010 are turned off. Again, the reservation and the turning off of the transmission beam not only consider the service requirement of the second network device, but also further consider whether there is another network device under the first network device, for example, there is a third network device under the first network device, which performs high frequency network communication through the transmission beam 0001, so that the transmission beam 0001 is useless for the second network device, but the transmission of the beam 0001 cannot be stopped because the beam 0001 is a downlink beam for performing high frequency network communication with the third network device; that is, the beam switching operation is determined according to the situation that the first network device belongs to all served network devices, and when a third network device exists in a certain transmission beam direction, the first network device is generally not allowed to stop at the transmission beam, and in addition, a "closing threshold" may be set for the transmission beam, for example, when the number of the third network devices in the certain transmission beam direction is lower than a certain number threshold, the transmission beam may be closed; optionally, before turning off, the third network device that originally performs high-frequency network communication through the transmission beam may be switched to other adjacent transmission beams first, and then the transmission beam is stopped.
In the data communication method provided by this embodiment, a first network device sends a first beam identification configuration message to a second network device through an established low-frequency communication link, so as to instruct the second network device to measure a beam of a currently transmitted beam identification signal, and selects a first beam of which a first measurement value meets a first threshold, where the currently transmitted beam is a part or all of beams of the first network device, so that the first network device establishes a high-frequency communication link with the second network device according to first beam selection information by receiving the first beam selection information sent by the second network device, and closes a part of beams of the currently transmitted beam identification signal; the method provided by the embodiment realizes the energy-saving requirement of the high-frequency station by turning on or off the beam for high-frequency network communication according to the service requirement, and solves the problem that the energy consumption of the high-frequency station is large due to the fact that the high-frequency station needs to continuously transmit the beam in each direction in the high-frequency communication mode in the prior art.
Further, in a high-frequency communication mode in the prior art, a terminal may have unnecessary measurement overhead and energy consumption, and it is difficult for a high-frequency station to achieve seamless coverage in all regions at an initial stage of network deployment, for example, high-frequency network communication is only used for data offloading in a hot spot area, and in an area without high-frequency network coverage, the terminal still performs measurement at a high-frequency point to try to access a high-frequency network, which is obviously useless operation; the method provided by the embodiment defines the conditions for accessing the high-frequency network, reduces the capacity consumption of the high-frequency station and the terminal accessing the high-frequency station, reduces the measurement overhead of the terminal, and correspondingly improves the energy conservation and intelligence of the high-frequency network communication system.
Optionally, fig. 3 is another schematic application scenario diagram provided in the embodiment shown in fig. 1, fig. 4 is another schematic application scenario diagram provided in the embodiment shown in fig. 1, the embodiment shown in fig. 3 takes a first network device as an eNB and a second network device as a relay as an example, the embodiment shown in fig. 4 takes the first network device as the eNB1 and the second network device is also an eNB2 as an example, and a specific manner of triggering high-frequency network communication in the embodiments shown in fig. 3 and fig. 4 is that, before S110, the method further includes: the first network device starts all the beams to transmit the beam identification signal according to a trigger condition, for example, the trigger condition in the embodiment shown in fig. 3 is: when the first network equipment detects that the resource occupancy rate of the low-frequency communication link is greater than the resource load threshold value, namely the eNB detects that subordinate low-frequency resources are insufficient, the eNB triggers the downlink between the eNB and the relay to be configured on the high-frequency communication link so as to reduce the load on the low-frequency communication link and achieve the purpose of shunting; the trigger conditions in the embodiment shown in fig. 4 are, for example: when the first network device determines that the amount of data to be transmitted between the first network device and the second network device is greater than the data transmission threshold, that is, there is a large data transmission requirement between the eNB1 and the eNB2, and the existing low-frequency communication link cannot meet the data transmission requirement, the eNB1 triggers configuring the communication link with the eNB2 on the high-frequency communication link.
It should be noted that, in the application scenarios in the embodiments shown in fig. 3 and fig. 4, since the relay and eNB2 as the second network device are both fixed with respect to the location of the first network device, only part of the beam transmission beam identification signal may be turned on; moreover, because the probability that the relay and eNB2 change the optimal beam is low, after the first network device acquires the beam for performing the high-frequency network communication, the remaining transmit beams may be stopped, and certainly, the transmit beams adjacent to the optimal transmit beam may also be retained, so that the robustness of the high-frequency communication link may be enhanced; in addition, when the second network device is a mobile relay, the transmission beam adjacent to the reserved optimal transmission beam can be generally used to ensure the beam reselection requirement caused by mobility, further, the number of the reserved beams and the adjacent range can be judged according to the moving speed of the relay, and if the moving speed of the relay is high, more transmission beams can be reserved; when the second network device is eNB2, eNB1 and eNB2 may each store an optimal transmission beam for transmitting the beam identification signal to the other, and directly open the stored beam to establish the high frequency communication link when the establishment of the high frequency communication link is triggered next time.
Further, fig. 5 is a flowchart of another data communication method according to an embodiment of the present invention. In this embodiment, the method provided in this embodiment further describes the method shown in fig. 1, and fig. 6 is an application scenario schematic diagram provided in the embodiment shown in fig. 5, and referring to the application scenario shown in fig. 2, where the first network device and the second network device have already established a high-frequency communication link, and the optimal downlink beam is 0100, and the optimal downlink beam is changed due to movement of the second network device UE, on the basis of the embodiment shown in fig. 1, the method in this embodiment may further include, after S130:
s140, the first network device receives a beam update request sent by the second network device through the low frequency communication link.
S150, the first network device turns on a third beam transmission beam identification signal according to the beam update request, where the third beam is a transmission beam in a preset range adjacent to the first beam.
The manner in which the first network device triggers the third beam transmission beam identification signal to be turned on according to the beam update request in this embodiment is similar to the manner in which the first network device turns on some or all of the beams to transmit the beam identification signal according to the high-frequency coverage request in the foregoing embodiments, except that the specific content of the triggered request message is different, and since the beam update request in this embodiment is sent at the location of the second network device, the turned-on third beam is usually a transmission beam in a preset range adjacent to the first beam determined in the foregoing embodiments.
S160, the first network device sends a second beam identification configuration message to the second network device through the low frequency communication link, where the second beam identification configuration message is used to instruct the second network device to measure the third beam, and select a fourth beam whose second measurement value meets a second threshold, where the second beam identification configuration message includes index information of the third beam.
S170, the first network device receives second beam selection information sent by the second network device through the low frequency communication link, where the second beam selection information includes index information corresponding to a fourth beam.
And S180, the first network equipment establishes a high-frequency communication link with the second network equipment according to the second beam selection information, and closes part of transmitting beams in the third beam.
Specifically, the implementation manners of S160 to S180 in this embodiment may refer to S110 to S130 in the embodiment shown in fig. 1, and the implementation manners and the beneficial effects thereof are the same as those in the above embodiment, and therefore are not described herein again.
Similarly to the foregoing embodiments, the fourth beam selected by the second network device in the embodiments of the present invention may be a beam with the best service quality, that is, a beam with the largest second measurement value, or may be multiple beams with service quality meeting a preset value, that is, multiple beams with a second measurement value greater than the second threshold value, for example, 6 beams with a second measurement value greater than the second threshold value, and 4 of the beams may be selected as the fourth beam according to a preset rule.
It should be noted that, when the second network device is triggered to reselect the optimal transmission beam due to movement of the second network device, if the second network device can find a beam meeting the requirement of communication quality on the transmission beam that is reserved when the first network device last selects the optimal transmission beam, the first network device may not be triggered to turn on the third beam transmission beam identification signal, and the second network device directly reports the transmission beam meeting the requirement of communication to the first network device, so that the first network device updates the downlink transmission beam for the second network device, without executing S140 to S180 in this embodiment. In this case, also taking the application scenario shown in fig. 6 as an example, the initial optimal beam of the UE is 0100, and the beam 0011 and the beam 0101 are transmission beams that are reserved by the first network device for ensuring the mobility of the second network device, after the second network device reselects from 0100 to 0101, there is no transmission beam reserved in the clockwise direction of the new optimal transmission beam, and in order to ensure the mobility of the second network device, the first network device may turn on the beam 0010 to transmit a beam identification signal, and since the third network device does not exist in the direction of the beam 0011, the transmission on the beam 0011 may be stopped.
Fig. 7 is a flowchart of another data communication method according to an embodiment of the present invention. The data communication method provided by this embodiment is suitable for the case of performing high frequency communication, and the method may be performed by a network device, where the network device is usually implemented in a hardware and software manner, and the network device performing the method provided by this embodiment may be, for example, a base station, a relay, or a UE. As shown in fig. 7, the method of this embodiment may include:
s210, the second network device receives a first beam identification configuration message sent by the first network device through the low frequency communication link, where the first beam identification configuration message is used to indicate that the first network device has turned on some or all beams to transmit beam identification signals.
Before the method provided in this embodiment is executed, the transmission beam of the first network device on the high frequency band is not always on, and is usually in a transmission stop state, and the beam identification signal transmitted by a part of or all the beams of the first terminal is turned on only when triggered by the high frequency communication service.
Also, referring to the application scenario shown in fig. 2, in this embodiment, the specific manner of triggering the high-frequency network communication further includes, before S210: s200, the second network device sends a high-frequency coverage request or a service request to the first network device through the low-frequency communication link, wherein the high-frequency coverage request or the service request comprises an identifier of the second network device, and the high-frequency coverage request or the service request is used for indicating the first network device to start a part of or all of beam transmitting beam identification signals. The high frequency coverage request or the service request in this embodiment is also sent by the UE to the eNB through the low frequency communication link, and the content of the high frequency coverage request and the role of the service request are the same as those in the above embodiment, and therefore, no further description is given here. It should be noted that, when the high-frequency coverage request or the service request sent by the second network device in S200 includes the location information of the second network device, the high-frequency coverage request or the service request is used to instruct the first network device to determine, according to the location information, a partial beam in the direction where the second network device is located, and turn on a partial beam transmission beam identification signal; when the high-frequency coverage request or the service request sent by the second network device does not include the location information of the second network device in S200, the high-frequency coverage request or the service request is used to instruct the first network device to start all beam transmitting beam identification signals; the present embodiment also assumes that the index information of the beam transmitting the beam identification signal is 0001, 0010, 0011, 0100, and 0101.
S220, the second network device measures the current transmission beam according to the first beam identification configuration message, and selects the first beam whose first measurement value satisfies the first threshold.
In this embodiment, the high-frequency coverage request may include, for example, a high-frequency band range supported by the second network device, and therefore, the beam of the transmission beam identification signal is a selected transmission beam on the high-frequency band specified in the high-frequency coverage request by the first network device, so that the second network device measures the transmission beam, and the second network device determines, based on the measurement identification of each beam, a downlink beam direction meeting the high-frequency communication requirement or a downlink beam whose service quality meets a preset condition as the first transmission beam. In a specific implementation, the second network device is synchronized with the first network device on the low frequency network, a time domain position where each beam identification signal is located on the high frequency band can be easily found, a frequency domain position where each beam identification signal is located is found on a specified high frequency bandwidth, the beams transmitting the beam identification signals are respectively measured for service quality, a first beam of which a first measurement value meets a first threshold is obtained, for example, a beam corresponding to the optimal signal power or the highest performance index value can be determined as an optimal transmission beam, that is, the first beam, index information of the optimal transmission beam is recorded, for example, a beam index of the first beam obtained by the second network device is 0100, and at this time, a selection process of a downlink optimal transmission beam is completed. It should be noted that, in this embodiment, the second network device may also use other performance indicators, such as a signal-to-noise ratio, a bit error rate, and the like, as a basis for selecting the first beam.
It should be noted that, the first beam identification configuration message in this embodiment may also include index information of the current transmission beam and resource information occupied by the transmission beam identification signal; s220 in this embodiment may include: and the second network equipment measures the current transmitting wave beam according to the resource position indicated by the resource information, and acquires the index information corresponding to the first wave beam according to the index information after selecting the first wave beam of which the first measurement value meets the first threshold value.
S230, the second network device sends first beam selection information to the first network device through the low frequency communication link, where the first beam selection information includes index information corresponding to the first beam, and the first beam selection information is used to instruct the first network device to establish a high frequency communication link with the second network device according to the first beam selection information, and close a part of beams currently transmitting the beam identification signal.
Similarly, the first beam in this embodiment may be a beam with the best service quality, that is, a beam with the largest first measurement value, or may be multiple beams with service quality satisfying a preset value, that is, multiple beams with a first measurement value greater than the first threshold value, and the index information corresponding to the first beam in this embodiment may be 0100, for example. The first network device in this embodiment may establish a high-frequency communication link with the second network device according to the first beam selected by the second network device, and may also close a part of beams of the currently transmitted beam identification signal after obtaining the optimal transmitted beam, and a specific manner in which the first terminal closes the transmitted beam is the same as in the above-described embodiment, and therefore details are not described here again.
In the data communication method provided in this embodiment, a second network device receives a first beam identification configuration message sent by a first network device through an established low-frequency communication link, measures a current transmission beam of the first network device, and selects a first beam whose first measurement value meets a first threshold, where the first beam identification configuration message is used to indicate that the first network device has started some or all of beam transmission beam identification signals, so that the second network device sends first beam selection information to the first network device through a low-frequency communication celloid to indicate that the first network device establishes a high-frequency communication link with the second network device through the first beam selection information, and closes some beams of the current transmission beam identification signals; the method provided by the embodiment realizes the energy-saving requirement of the high-frequency station by turning on or off the beam for high-frequency network communication according to the service requirement, and solves the problem that the energy consumption of the high-frequency station is large due to the fact that the high-frequency station needs to continuously transmit the beam in each direction in the high-frequency communication mode in the prior art.
Further, in a high-frequency communication mode in the prior art, a terminal may have unnecessary measurement overhead and energy consumption, and it is difficult for a high-frequency station to achieve seamless coverage in all regions at an initial stage of network deployment, for example, high-frequency network communication is only used for data offloading in a hot spot area, and in an area without high-frequency network coverage, the terminal still performs measurement at a high-frequency point to try to access a high-frequency network, which is obviously useless operation; the method provided by the embodiment defines the conditions for accessing the high-frequency network, reduces the capacity consumption of the high-frequency station and the terminal accessing the high-frequency station, reduces the measurement overhead of the terminal, and correspondingly improves the energy conservation and intelligence of the high-frequency network communication system.
Optionally, referring to the application scenarios shown in fig. 3 and fig. 4 as well, the condition for the first network device to trigger the high-frequency network communication may be further: the first network equipment detects that the resource occupancy rate of the low-frequency communication link is greater than a resource load threshold value; or the first network device determines that the data volume to be transmitted between the first network device and the second network device is greater than the data transmission threshold.
Further, fig. 8 is a flowchart of another data communication method according to an embodiment of the present invention. In the method provided by this embodiment, further description of the method shown in fig. 7 is provided, and also with reference to the application scenarios shown in fig. 6 and fig. 2, the first network device and the second network device have already established the high-frequency communication link, and the optimal downlink beam is 0100, and the optimal downlink beam is changed due to movement of the second network device UE, on the basis of the embodiment shown in fig. 7, the method of this embodiment may further include:
s240, the second network device sends a beam update request to the first network device through the low frequency communication link, where the beam update request is used to instruct the first network device to turn on a third beam transmission beam identification signal according to the beam update request, and the third beam is a transmission beam in a preset range adjacent to the first beam.
The manner in which the second network device sends the beam update request to trigger the turning on of the third beam transmission beam identification signal in this embodiment is similar to the manner in which the second network device sends the high-frequency coverage request to trigger the turning on of some or all of the beam transmission beam identification signals in the foregoing embodiments, except that the specific content of the triggered request message is different, because the beam update request in this embodiment is sent in the location transmission change of the second network device, the turned on third beam is usually a transmission beam in the preset range adjacent to the first beam determined in the foregoing embodiments.
And S250, the second network equipment receives a second beam identification configuration message sent by the first network equipment through the low-frequency communication link.
S260, the second network device measures the third beam according to the second beam identification configuration message, and selects a fourth beam whose second measurement value satisfies the second threshold.
And S270, the second network device sends second beam selection information to the first network device through the low-frequency communication link, the second beam selection information includes index information corresponding to a fourth beam, and the second beam selection information is used for indicating the first network device to establish a high-frequency communication link with the second network device according to the second beam selection information and closing part of beams in the third beam.
Specifically, the implementation manners of S250 to S270 in this embodiment may refer to S210 to S230 in the embodiment shown in fig. 7, and the implementation manners and the beneficial effects thereof are the same as those in the above embodiment, and therefore are not described herein again.
