[0098] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will further describe the specific technical solutions of the application in detail with reference to the accompanying drawings in the embodiments of this application. The following embodiments are used to illustrate this application but are not intended to limit the scope of this application.

[0099] In the following description, "some embodiments" are involved, which describe a subset of all possible embodiments. However, it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments and can be combined with each other without conflict.

[0100] In the following description, the terms "first / second / third" are only used to distinguish different objects and do not represent a specific order for the objects, without the limitation of a sequential order. It can be understood that "first / second / third" can be interchanged with a specific order or sequence when allowed, so that the embodiments of this application described here can be implemented in an order other than that illustrated or described here.

[0101] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0102] In a first aspect, a wireless communication method provided by the embodiments of this application is applied to a first device, as Figure 1 shown, and includes:

[0103] S101. Receive the millimeter - wave transmission configuration information of a second device on an unlicensed band.

[0104] S102. Communicate with the second device on the millimeter - wave band based on the millimeter - wave transmission configuration information of the second device.

[0105] In a second aspect, a wireless communication method provided by the embodiments of this application is applied to a second device, as Figure 2As shown in the figure, it includes:

[0106] S201. Send the millimeter-wave transmission configuration information of the second device on the unlicensed frequency band.

[0107] S202. Communicate with the first device on the millimeter-wave frequency band based on the millimeter-wave transmission configuration information of the second device.

[0108] Thirdly, a wireless communication method provided by an embodiment of the present application is applied to a wireless communication system including a first device and a second device. As Figure 3 shown in the figure, it includes:

[0109] S301. The second device sends the millimeter-wave transmission configuration information of the second device to the first device on the unlicensed frequency band.

[0110] S302. The first device and the second device communicate on the millimeter-wave frequency band based on the millimeter-wave transmission configuration information of the second device.

[0111] Next, a description is given of the Figure 1 , Figure 2 or Figure 3 wireless communication method shown in the figure.

[0112] Here, the unlicensed frequency band refers to a radio frequency band that can be used without separate authorization from the government or regulatory agency. Among them, the unlicensed frequency band is a frequency band less than 7 gigahertz (GHz). For example, the 1 GHz frequency band, 2.4 GHz frequency band, 5 GHz frequency band, and 6 GHz frequency band. The second device refers to the device that sends data scheduling information. The first device refers to the device that receives data scheduling information and sends data according to the data scheduling information. The millimeter-wave transmission configuration information can be used to characterize the device's ability to support millimeter-wave transmission. The millimeter-wave frequency band refers to the electromagnetic wave with a frequency between 30 GHz and 300 GHz, and its wavelength range is from 1 millimeter to 10 millimeters. This frequency band is located in the wavelength range where microwaves and far-infrared waves overlap, so it has the characteristics of both spectra.

[0113] In some embodiments, the first device may be a management node, and the second device may be an in-domain device node of the management node. Among them, the second device is located within the coverage range of the first device. The first device may be an authorized (Grant, G) node, and the second device may be a managed (Terminal, T) node located within the signal coverage range of the G node.

[0114] In some embodiments, the first device may be a base station, and the second device may be a terminal located within the signal coverage range of the base station.

[0115] In some embodiments, the millimeter-wave transmission configuration information may include at least one of the following: first information, second information, and third information. Among them, the first information is used to indicate the frequency band supported by the millimeter-wave band; the second information is used to indicate the number of antenna transmission ports supported on the millimeter-wave band; the third information is used to indicate the number of transmission beams and / or reception beams supported on the millimeter-wave band.

[0116] In one example, the first information may be millimeter-wave band information, and the millimeter-wave band information includes the millimeter-wave center frequency point position and the number of sub-bands; the first information may also be parameters such as frequency range, bandwidth, and spectral utilization rate. The second information may be the number of antenna transmission ports supported by digital domain beamforming. The third information may be the number of transmission and / or reception beams supported by analog domain beamforming, and the third information may also be parameters such as beam width, beamforming ability, and beam management strategy.

[0117] It can be understood that the millimeter-wave center frequency point position is the basic frequency when the first device communicates with the second device. After the first device obtains the millimeter-wave center frequency point position of the second device, it can adjust the corresponding parameters so that the signals transmitted and received by the first device are at the same frequency as the second device, enabling the frequency synchronization between the first device and the second device, reducing the signal interference between the first device and the second device, and improving the communication quality. The number of sub-bands reflects the division of the millimeter-wave signal in the frequency domain. After the first device obtains the number of sub-bands of the second device, it can adjust the corresponding parameters so that the first device can more effectively utilize the bandwidth resources of the millimeter-wave band and improve the communication efficiency.

[0118] Digital domain beamforming technology relies on multiple ports in the antenna array to transmit and receive signals. By informing the first device of the number of antenna transmission ports supported by digital domain beamforming, the second device can make the first device compatible with the network infrastructure when configuring and using the ports, avoiding communication failures caused by port mismatches. In addition, different numbers of antenna ports may correspond to different beamforming capabilities and communication performances. The first device can also select an appropriate number of ports for configuration according to its own communication requirements and performance requirements, thereby optimizing the communication performance.

[0119] Analog domain beamforming technology relies on the antenna array and the corresponding beamforming algorithm. By informing the first device of the number of transmission and / or reception beams supported by analog domain beamforming, the second device enables the first device to correctly set the beam parameters during configuration, avoiding communication failures caused by configuration errors. In addition, different first devices may support different numbers of transmission and / or reception beams. In this way, when the first device transmits through millimeter waves, it selects appropriate communication parameters according to its own beamforming ability, thereby enhancing the compatibility between the first device and the second device.

[0120] In some embodiments, the millimeter-wave transmission configuration information of the second device may be determined by the second device based on factors such as network planning, frequency band allocation, and antenna configuration.

[0121] In some other embodiments, the millimeter-wave configuration information of the second device may also be set by the user through a relevant interface based on the millimeter-wave transmission capability of the second device.

[0122] In some embodiments, after the first device receives the millimeter-wave transmission configuration information of the second device, first, it parses the millimeter-wave transmission configuration information of the second device, and adjusts its own relevant parameters according to the parsed millimeter-wave transmission configuration information of the second device. For example, it may include antenna parameters, beamforming parameters, etc., so that the communication parameters of the first device and the second device match, improving the quality of the communication link established between the first device and the second device to ensure the stability and reliability of the communication between the first device and the second device. Then, when the first device wants to send data to the second device, the first device modulates the data to be sent to generate a signal suitable for millimeter-wave transmission, and sends it to the second device through the millimeter-wave link between the first device and the second device, realizing the communication between the first device and the second device.

[0123] In some embodiments, the second device communicates with the first device based on the millimeter-wave transmission configuration information of the second device in the millimeter-wave frequency band, which may be that the millimeter-wave transmission configuration information of the first device is preset in the second device, so that the communication between the first device and the second device can be realized without the first device sending the millimeter-wave transmission configuration information of the first device to the second device.

[0124] In an example, the millimeter-wave transmission configuration information of the first device is set as follows: the number of antenna transmit ports supported by digital domain beamforming is 1, the number of transmit and receive beams supported by analog domain beamforming is 1, and the millimeter-wave frequency band information may be allocated by the second device.

[0125] In an example, when the number of the first device and the second device is both 1, it is possible to make the first device not need to send the millimeter-wave transmission configuration information of the first device to the second device.

[0126] In the embodiments of the present application, first, after the first device receives the millimeter-wave transmission configuration information of the second device, the first device can configure millimeter-wave transmission-related parameters based on the millimeter-wave transmission configuration information of the second device, realizing millimeter-wave configuration in the unlicensed band. Then, based on the millimeter-wave transmission-related parameter configuration completed by the first device, the first device can communicate with the second device via millimeter waves, realizing high-frequency band transmission in the unlicensed band, thereby realizing the high-rate data transmission requirement in the unlicensed band and increasing the application scenarios of the unlicensed band.

[0127] In some embodiments, receiving the millimeter-wave transmission configuration information of the second device sent by the second device in the unlicensed band in S101 includes: receiving the millimeter-wave transmission configuration information of the second device broadcast by the second device in the unlicensed band.

[0128] In some embodiments, the second device can broadcast a broadcast message in the unlicensed band, and the broadcast message includes the millimeter-wave transmission configuration information of the second device.

[0129] In some embodiments, by broadcasting the millimeter-wave transmission configuration information of the second device, all the first devices corresponding to the second device can receive the millimeter-wave transmission configuration information of the second device.

[0130] In some embodiments, it can be that the second device periodically broadcasts the millimeter-wave transmission configuration information of the second device in the unlicensed band.

[0131] It can be understood that through the above broadcast sending method, the transmission of the millimeter-wave transmission configuration information of the second device is given to all the devices that interact with the second device for messages. Therefore, the millimeter-wave transmission configuration information of the second device can be sent to the first device by the broadcast sending method.

[0132] Receiving the millimeter-wave transmission configuration information of the second device sent by the second device in the unlicensed band in S101 includes: receiving the millimeter-wave transmission configuration information of the second device sent by the second device to the first device in the unlicensed band.

[0133] In some embodiments, the second device sends the millimeter-wave transmission configuration information of the second device to the first device according to the communication identifier corresponding to the first device.

[0134] In some embodiments, the millimeter-wave transmission configuration information of the second device can be sent by the second device from the management node direction communication link to the first device, where the management node direction communication connection can be implemented as a G link or a downlink.

[0135] In some embodiments, the second device may broadcast the millimeter-wave transmission configuration information of the second device on an unlicensed band in response to the first millimeter-wave configuration query information sent by the first device.

[0136] It can be understood that by the above unicast sending method, the millimeter-wave transmission configuration information of the second device is only transmitted to a specific receiver, which can reduce unnecessary traffic consumption. However, in the case of multiple receivers, the same data packet needs to be sent multiple times by the unicast sending method, which will cause waste of bandwidth resources. Therefore, the unicast sending method can be applied when the first device associated with the second device is single.

[0137] In the embodiments of the present application, two sending methods for the millimeter-wave transmission configuration information of the second device are described, so that the second device can select a sending method adapted to the number of first devices for sending, effectively utilizing the network resources of the unlicensed band.

[0138] In some embodiments, based on Figure 1 the wireless communication method shown, the wireless communication method provided by the embodiments of the present application further includes: sending first millimeter-wave configuration query information to a second device on an unlicensed band, where the first millimeter-wave configuration query information is used to trigger the second device to send the millimeter-wave transmission configuration information of the second device.

[0139] Here, when the first device supports the millimeter-wave band, the first millimeter-wave configuration query information is sent to the second device.

[0140] In some embodiments, after the first device accesses the second device and determines that the domain supports millimeter-wave transmission, the first device sends a first millimeter-wave configuration query request to the second device. After receiving the first millimeter-wave configuration query request sent by the first device, the second device sends the millimeter-wave transmission configuration information of the second device to the first device.

[0141] In some embodiments, the first device may send the first millimeter-wave configuration query request to the second device through a terminal node direction communication link, where the terminal node direction communication link may be a T link or an uplink.

[0142] In implementation, the first device may send the first millimeter-wave configuration query request to the second device in the link establishment related message between the first device and the second device, where the link establishment related message may be a T link dedicated control message or an uplink dedicated control message.

[0143] Correspondingly, based on Figure 2The wireless communication method shown. The wireless communication method provided by the embodiments of the present application further includes: receiving, on an unlicensed frequency band, first millimeter-wave configuration query information sent by a first device; and based on the trigger of the first millimeter-wave configuration query information, sending, on the unlicensed frequency band, millimeter-wave transmission configuration information of a second device to the first device.

[0144] In the embodiments of the present application, the trigger condition for the second device to send the millimeter-wave transmission configuration information of the second device is described. In this way, when the trigger condition is met, the first device can receive the millimeter-wave transmission configuration information of the second device, so that the first device can communicate with the second device in the millimeter-wave frequency band based on the millimeter-wave transmission configuration information of the second device.

[0145] In some embodiments, based on Figure 1 the wireless communication method shown. The wireless communication method provided by the embodiments of the present application further includes: sending, on an unlicensed frequency band, millimeter-wave transmission configuration information of a first device to a second device; and communicating with the second device in the millimeter-wave frequency band based on the millimeter-wave transmission configuration information of the second device and the millimeter-wave transmission configuration information of the first device.

[0146] In some embodiments, after the first device obtains the millimeter-wave transmission configuration information of the first device and the millimeter-wave transmission configuration information of the second device, it can adjust its own millimeter-wave transmission related parameters based on the millimeter-wave transmission configuration information of the second device to match the millimeter-wave transmission configuration information of the second device. For example, the first device can adjust its transmit and receive beams according to the number of transmit and receive beams supported by the analog domain beamforming of the second device.

[0147] In some embodiments, after adapting the millimeter-wave transmission related parameters of the first device to the millimeter-wave transmission configuration information of the second device, during the data transmission process between the first device and the second device, the communication quality between the first device and the second device can be guaranteed, and the communication efficiency between the first device and the second device can be improved.

[0148] Correspondingly, based on Figure 2 the wireless communication method shown. The wireless communication method provided by the embodiments of the present application further includes: receiving, on an unlicensed frequency band, millimeter-wave transmission configuration information of a first device sent by the first device; and communicating with the first device in the millimeter-wave frequency band based on the millimeter-wave transmission configuration information of the second device and the millimeter-wave transmission configuration information of the first device.

[0149] In some embodiments, the second device can determine the frequency bands supported by the first device in the millimeter-wave band through the millimeter-wave transmission configuration information of the first device. In this way, the second device can accurately configure the communication channel between the first device and the second device, ensuring the stability and reliability of the signal during transmission, thereby improving the communication quality. In addition, since the millimeter-wave band has an extremely high bandwidth and can support high-speed data transmission, the second device can also optimize the transmission strategy based on the frequency bands supported by the first device in the millimeter-wave band to increase the data transmission rate.

[0150] In some embodiments, the second device can determine the number of antenna transmit ports supported by the first device in the millimeter-wave band through the millimeter-wave transmission configuration information of the first device. In this way, the second device can adjust the beamforming strategy based on the number of antenna transmit ports supported by the first device in the millimeter-wave band to ensure that the beam can accurately align with the first device, thereby reducing signal interference and improving the communication quality.

[0151] In some other embodiments, the second device can also dynamically adjust the allocation of spectrum resources based on the number of antenna transmit ports supported by all the first devices in the millimeter-wave band, maximizing the utilization of spectrum resources and improving the communication efficiency of the entire network.

[0152] In some embodiments, the second device can determine the number of transmit beams and / or receive beams supported by the first device in the millimeter-wave band through the millimeter-wave transmission configuration information of the first device. In this way, based on the number of transmit beams and / or receive beams supported by the first device in the millimeter-wave band, on the one hand, the beamforming can be adjusted to achieve beam alignment with the first device, which helps to reduce signal interference and improve the signal quality; on the other hand, the communication resources can be flexibly configured. For example, when the number of beams is large, the second device can allocate more spectrum resources or adopt a more efficient modulation and coding method to further improve the communication performance.

[0153] In some embodiments, after receiving the millimeter-wave transmission configuration information of the first device, the second device first parses the millimeter-wave transmission configuration information of the first device and adjusts its own millimeter-wave transmission related parameters according to the parsed millimeter-wave transmission configuration information of the first device. For example, it can include antenna array configuration, beamforming parameters, etc., so that the communication parameters of the first device and the second device match, which can improve the quality of the millimeter-wave link established between the first device and the second device to ensure the stability and reliability of the communication between the first device and the second device. Then, when the second device wants to send data to the first device, the second device modulates the data to be sent to generate a signal suitable for millimeter-wave transmission and sends it to the first device through the millimeter-wave link between the first device and the second device, realizing the communication between the first device and the second device.

[0154] In some embodiments, based on the millimeter-wave transmission configuration information of the second device and the millimeter-wave transmission configuration information of the first device, the signal transmission format during the communication between the first device and the second device via millimeter waves can also be selected and configured, so that the first device and the second device can parse the received signals or encapsulate the signals to be sent based on the signal transmission format.

[0155] In the embodiments of the present application, first, after the first device sends the millimeter-wave transmission configuration information of the first device to the second device, the first device and the second device can configure the parameters related to millimeter-wave transmission based on the millimeter-wave transmission configuration information of the second device and the millimeter-wave transmission configuration information of the first device, realizing the millimeter-wave configuration in the unlicensed band. Then, based on the parameters related to millimeter-wave transmission completed by the first device, the first device can communicate with the second device via millimeter waves, realizing the high-frequency band transmission in the unlicensed band and increasing the application scenarios of multi-band transmission in the unlicensed band.

[0156] In some embodiments, based on Figure 1 the wireless communication method shown in, the wireless communication method provided by the embodiments of the present application further includes: receiving, via the first transceiver, the second millimeter-wave configuration query information sent by the second device in the unlicensed band; and sending, based on the trigger of the second millimeter-wave configuration query information, the millimeter-wave transmission configuration information of the first device to the second device via the first transceiver in the unlicensed band.

[0157] Correspondingly, based on Figure 2 the wireless communication method shown in, the wireless communication method provided by the embodiments of the present application further includes: sending the second millimeter-wave configuration query information to the first device in the unlicensed band; and receiving the millimeter-wave transmission configuration information of the first device sent by the first device.

[0158] In the embodiments of the present application, the trigger condition for the first device to send the millimeter-wave transmission configuration information of the first device is described. In this way, when the trigger condition is met, the second device receives the millimeter-wave transmission configuration information of the first device, so that the second device can communicate with the first device in the millimeter-wave band based on the millimeter-wave transmission configuration information of the first device and the millimeter-wave transmission configuration information of the second device.

[0159] In some embodiments, based on Figure 3 the wireless communication method, as Figure 4 shown, further includes:

[0160] S303. The first device sends the first millimeter-wave configuration query information to the second device in the unlicensed band;

[0161] Correspondingly, S301 is described as: Based on the trigger of the first millimeter-wave configuration query information, the second device sends the millimeter-wave transmission configuration information of the second device to the first device on the unlicensed band;

[0162] S304. The second device sends second millimeter-wave configuration query information to the first device on the unlicensed band;

[0163] S305. Based on the trigger of the second millimeter-wave configuration query information, the first device sends the millimeter-wave transmission configuration information of the first device to the second device on the unlicensed band.

[0164] Correspondingly, S302 is described as: The second device and the first device implement two-way communication on the millimeter-wave band based on the millimeter-wave transmission configuration information of the second device and the millimeter-wave transmission configuration information of the first device.

[0165] In some embodiments, based on Figure 1 the shown wireless communication method, before S101, the wireless communication method provided by the embodiments of the present application further includes: receiving, on the unlicensed band, first indication information broadcast by the second device, where the first indication information is used to indicate whether the second device supports the millimeter-wave band; or, receiving, on the unlicensed band, first indication information sent by the second device to the first device.

[0166] In some embodiments, when the first device is not connected to the second device, the second device broadcasts the first indication information on the unlicensed band.

[0167] In other embodiments, when the first device is connected to the second device, the second device sends the first indication information to the first device on the unlicensed band.

[0168] In some embodiments, the first indication information can be represented by 0 and 1. During implementation, 1 indicates that the second device supports the millimeter-wave band, 0 indicates that the second device does not support the millimeter-wave band, or 0 indicates that the second device supports the millimeter-wave band, and 1 indicates that the second device does not support the millimeter-wave band.

[0169] In some embodiments, after receiving the first indication information, the first device parses the first indication information and determines whether the second device supports the millimeter-wave band based on the parsed first indication information.

[0170] In some embodiments, after determining that the second device supports the millimeter-wave band, the first device obtains the millimeter-wave transmission configuration information of the second device.

[0171] It can be understood that by using the above unicast transmission method, the first indication information is only transmitted to a specific receiver, which can reduce unnecessary traffic consumption. However, when there are multiple receivers, the same data packet needs to be sent multiple times through the unicast transmission method, which will cause waste of bandwidth resources. Therefore, if there is a single receiver, the first indication information can be sent to the first device through the unicast transmission method. If there are multiple receivers, if the unicast method is still used to send the first indication information, it will cause waste of bandwidth and even network congestion, affecting network performance. Therefore, in this scenario, the first indication information can be sent through the broadcast method.

[0172] In the embodiments of the present application, by receiving the first indication information sent by the second device, it can be determined whether the second device supports the millimeter wave band. In this way, when the second device supports the millimeter wave band, the transmission of the millimeter wave transmission configuration information of the second device is triggered subsequently.

[0173] Correspondingly, based on Figure 2 the wireless communication method shown, before S201, the wireless communication method provided by the embodiments of the present application further includes: broadcasting the first indication information on the unlicensed band; or, sending the first indication information to the first device on the unlicensed band.

[0174] In some embodiments, when there are multiple first devices under the second device, the second device can send the first indication information to the first devices by broadcasting.

[0175] In other embodiments, when there is a single first device under the second device, the second device can send the first indication information to the first device by unicast.

[0176] Correspondingly, based on Figure 3 the wireless communication method shown, as Figure 5 shown, it further includes:

[0177] S306. The second device broadcasts the first indication information on the unlicensed band.

[0178] S307. Trigger the transmission of the millimeter wave transmission configuration information of the second device.

[0179] Here, the specific implementation of S307 includes S303 and S301.

[0180] In some embodiments, based on Figure 1 the wireless communication method shown, the wireless communication method provided by the embodiments of the present application further includes: sending the second indication information to the second device on the unlicensed band, where the second indication information is used to indicate whether the first device supports the millimeter wave band.

[0181] In some embodiments, the second indication information may be reported to the second device after the first device accesses the second device. During implementation, the second indication information may be sent by the first device when reporting the device capabilities to the second device.

[0182] In some embodiments, 0 and 1 may be used to represent the second indication information. During implementation, 1 indicates that the first device supports the millimeter wave band, and 0 indicates that the first device does not support the millimeter wave band. Alternatively, 0 indicates that the first device supports the millimeter wave band, and 1 indicates that the first device does not support the millimeter wave band.

[0183] In some embodiments, when the second device determines that the first device supports the millimeter wave band, the second device may send second millimeter wave configuration query information to the first device.

[0184] Correspondingly, based on Figure 3 the wireless communication method shown, such as Figure 6 shown, further includes:

[0185] S303. The first device sends first millimeter wave configuration query information to the second device on the unlicensed band;

[0186] Correspondingly, S301 is described as: The second device sends the millimeter wave transmission configuration information of the second device to the first device on the unlicensed band based on the trigger of the first millimeter wave configuration query information;

[0187] S308. The first device sends second indication information to the second device on the unlicensed band;

[0188] Correspondingly, S304 is described as: The second device sends second millimeter wave configuration query information to the first device on the unlicensed band based on the trigger of the second indication information;

[0189] S305. The first device sends the millimeter wave transmission configuration information of the first device to the second device on the unlicensed band based on the trigger of the second millimeter wave configuration query information.

[0190] Correspondingly, S302 is described as: The second device and the first device perform two-way communication on the millimeter wave band based on the millimeter wave transmission configuration information of the second device and the millimeter wave transmission configuration information of the first device.

[0191] In the embodiments of the present application, by the second indication information sent by the first device, it can be determined whether the first device supports the millimeter wave band. In this way, when the first device supports the millimeter wave band, the subsequent trigger for transmitting the millimeter wave transmission configuration information of the first device is performed.

[0192] In some embodiments, based on Figure 1The wireless communication method shown. The wireless communication method provided by the embodiments of the present application further includes: receiving or sending first control information on an unlicensed frequency band; and performing data transmission on a millimeter wave frequency band based on the first control information.

[0193] Here, the first control information is used to indicate the data transmission format for transmission on the millimeter wave to control data transmission on the millimeter wave link, where the data transmission may include the transmission of measurement reference signals for performance detection, or may also include the transmission of communication data between a first device and a second device.

[0194] In some embodiments, the first control information may be information for indicating data transmission on the millimeter wave frequency band. The first control information may also be information for indicating control information transmission on the millimeter wave frequency band.

[0195] In the embodiments of the present application, based on the first control information on the unlicensed frequency band, data transmission on the millimeter wave frequency band is realized, high-frequency band transmission based on the unlicensed frequency band is realized, and the application scenarios of multi-band transmission on the unlicensed frequency band are increased.

[0196] In some embodiments, based on Figure 1 The wireless communication method shown. The above-mentioned performing data transmission on the millimeter wave frequency band based on the first control information includes: performing data transmission on the millimeter wave frequency band based on the scheduling of the first control information.

[0197] Here, the first control information may be information for indicating the transmission of communication data or measurement reference signals on the millimeter wave frequency band, and the first control information carries control information related to communication data or measurement reference signals.

[0198] In some embodiments, the first control information may include information related to the frequency band and / or time domain (time slot) where the data transmission is located, for example, the center frequency point position of the frequency band; indication information related to the data transmission block, for example, whether it is a retransmission transmission block and the specific coding block scheme; demodulation reference signal configuration information, for example, the port number and type, etc.; modulation and coding method indication information; frequency resource scheduling indication, for example, the resource block indication scheduled; other information related to data physical layer transmission, for example, the analog beam ID number.

[0199] In some embodiments, the first control information may be used on a G link or a T link.

For the first control information on the T link, the first control information may be used to schedule the transmission of communication data or measurement reference signals on the T link.

[0200] In some other embodiments, the first control information can be used on the downlink or the uplink. Among them, for the first control information on the downlink, the first control information can be used to schedule the transmission of communication data or measurement reference signals on the uplink or the downlink. For the first control information on the uplink, the first control information can be used to schedule the transmission of communication data or measurement reference signals on the uplink.

[0201] In some embodiments, it can be when transmitting G-link control information or T-link control information, adding the first control information to the G-link control information or T-link control information.

[0202] In some other embodiments, it can be when transmitting uplink control information or downlink control information, adding the first control information to the uplink control information or downlink control information.

[0203] In some embodiments, as Figure 7A shown, the first control information 1 can be located in the unlicensed band 2, so that through the first control information 1, the transmission of data and reference signals 4 in the millimeter wave band 3 can be achieved.

[0204] In some embodiments, the first control information can be generated by encoding and identifying the generated cyclic redundancy bits using a dedicated information mask.

[0205] In the embodiments of the present application, a data transmission method is described in which the communication data or measurement reference signals are directly indicated by the first control information to be transmitted in the millimeter wave band, realizing the high-frequency band transmission of data based on the unlicensed band and increasing the application scenarios of multi-band transmission in the unlicensed band.

[0206] In some embodiments, the above-mentioned data transmission in the millimeter wave band based on the first control information includes: based on the scheduling of the first control information, transmitting the second control information in the millimeter wave band; based on the scheduling of the second control information, transmitting data in the millimeter wave band.

[0207] Here, the first control information can be information used to indicate the control information transmission in the millimeter wave band, that is, the first control information is used to indicate the sending of the second control information. The second control information can be information in the millimeter wave band used to indicate the transmission of communication data or measurement reference signals in the millimeter wave band, that is, the second control information is the control information sent in the millimeter wave band, and the second control information carries the control information related to the communication data or measurement reference signals.

[0208] In some embodiments, the first control information and the second control information can be used on the G link or the T link. Among them, for the first control information and the second control information on the G link, they can be used to schedule the transmission of communication data or measurement reference signals on the G link or the T link. For the first control information and the second control information on the T link, they can be used to schedule the transmission of communication data or measurement reference signals on the T link.

[0209] In other embodiments, the first control information and the second control information can be used on the downlink or the uplink. Among them, for the first control information and the second control information on the downlink, they can be used to schedule the transmission of communication data or measurement reference signals on the uplink or the downlink. For the first control information and the second control information on the uplink, the first control information and the second control information can be used to schedule the transmission of communication data or measurement reference signals on the uplink.

[0210] In some embodiments, the first control information may include information related to the frequency band where data is transmitted, for example, the center frequency point position of the frequency band; demodulation reference signal configuration information, for example, port number and type, etc.

[0211] In some embodiments, the second control information may include data transmission block related indication information, for example, whether it is a retransmitted transmission block and the specific coding block scheme; demodulation reference signal configuration information, for example, port number and type, etc.; modulation and coding method indication information; frequency resource scheduling indication, for example, the resource block indication scheduled; other information related to data physical layer transmission, for example, analog beam ID number.

[0212] In some embodiments, it may be when transmitting G link control information or T link control information, adding the first control information and the second control information to the G link control information or T link control information.

[0213] In other embodiments, it may be when transmitting uplink control information or downlink control information, adding the first control information and the second control information to the uplink control information or downlink control information.

[0214] In some embodiments, as Figure 7B shown, the first control information 1 may be located in the unlicensed frequency band 2, and the first control information 1 is used to indicate the transmission of the second control information 5. The second control information is located in the millimeter wave frequency band 3, and the second control information 5 is used to implement the transmission of data and reference signals 4 in the millimeter wave frequency band 3.

[0215] In some embodiments, the first control information and the second control information may be generated after encoding and identifying the generated cyclic redundancy bits using a dedicated information mask.

[0216] In the embodiments of the present application, a data transmission method is described in which communication data or a measurement reference signal is indirectly indicated by first control information to be transmitted in the millimeter-wave frequency band, realizing data transmission based on a high-frequency band in an unlicensed frequency band and increasing the application scenarios of multi-band transmission in the unlicensed frequency band.

[0217] In some embodiments, based on Figure 1 the wireless communication method shown, the wireless communication method provided by the embodiments of the present application further includes: receiving, in an unlicensed frequency band, fourth information sent by a second device, where the fourth information is used to configure a measurement reference signal in the millimeter-wave frequency band and the beam used for the measurement reference signal; receiving a first measurement reference signal on a link in the millimeter-wave frequency band based on the fourth information; determining a measurement result of the link based on the first measurement reference signal; and sending the measurement result to the second device in the unlicensed frequency band.

[0218] Here, the measurement reference signal can be a signal used in a wireless communication system for measuring and estimating channel state, signal quality, and synchronization. Therefore, the receiving end can use them to evaluate the performance of the current communication link.

[0219] In some embodiments, the fourth information can be implemented by setting in a measurement report configuration information (measreportConfig).

[0220] In some embodiments, the fourth information may include: the port number of the antenna transmission port used for the measurement reference signal and the analog transceiver beam ID number, the type of measurement result feedback by the device node, and the corresponding quantization configuration.

[0221] It can be understood that in a beamforming communication system, the channel conditions or signal qualities corresponding to different beams are different. Thus, by associating the port number of the antenna transmission port used for the measurement reference signal and the analog transceiver beam ID number used, and transmitting the measurement reference signal through a specified beam, the measurement result can be associated with a specific beam, and the performance of the beam can be accurately evaluated.

[0222] The device node feeds back the measurement reference signal receiving quality value result type of layer 1 and the corresponding quantization configuration measured. Among them, the reference signal receiving quality value result type may include Reference Signal Receiving Power (RSRP) and / or Reference Signal Receiving Quality (RSRQ); the corresponding quantization configuration is used to characterize how to quantify the measurement result, that is, the corresponding quantization configuration is used to indicate the quantization accuracy of the measurement result obtained based on the measurement reference signal receiving quality value. For example, the measurement reference signal receiving quality value is quantized by 3 bits, or the measurement reference signal receiving quality value is quantized by 4 bits. In this way, the performance evaluation and signal quality evaluation of the millimeter-wave link can be realized by the device node feeding back the measurement reference signal receiving quality value of layer 1 and the corresponding quantization configuration.

[0223] In some embodiments, the measurement reference signal can be used for the measurement of the G link, and the measurement reference signal can be a channel state information reference signal, a phase tracking reference signal, etc.

[0224] In other embodiments, the measurement reference signal can be a custom reference signal.

[0225] In some embodiments, first, after the first device receives the first measurement reference signal, the first device performs signal processing operations such as signal demodulation, filtering, and synchronization on the first measurement reference signal to obtain the signal information in the first measurement reference signal. Then, the first device performs channel estimation based on the signal information in the first measurement reference signal to obtain the measurement result of the link.

[0226] In some embodiments, after the second device receives the measurement result of the link, the second device compares the measurement result with a preset communication quality condition. When the measurement result meets the communication quality condition, it is determined to transmit communication data or a measurement reference signal through the millimeter-wave frequency band. When the measurement result does not meet the communication quality condition, it is determined to transmit communication data or a measurement reference signal through the unlicensed frequency band.

[0227] In the embodiments of the present application, the communication quality of the millimeter-wave link can be monitored based on the measurement result of the millimeter-wave link, avoiding problems such as data loss and / or slow transmission efficiency caused by abnormal communication quality problems of the millimeter-wave link.

[0228] Correspondingly, based on Figure 3 the shown wireless communication method, as Figure 8 shown, during the implementation of S302, the wireless communication method provided by the embodiments of the present application further includes:

[0229] S309. Establish a millimeter-wave link between the first device and the second device.

[0230] S310. The second device sends the fourth information to the first device.

[0231] S311. The first device receives the first measurement reference signal on the millimeter-wave frequency band link based on the fourth information.

[0232] S312. The first device determines the measurement result of the link based on the first measurement reference signal.

[0233] S313. The first device sends the measurement result to the second device on the unlicensed frequency band.

[0234] It should be noted that the execution order of S310 and S309 in this application is not restricted. During implementation, S309 can be executed before S310 or after S310.

[0235] Next, the wireless communication method provided by the embodiments of this application will be described.

[0236] With the large-scale commercial deployment of 5G networks, a large number of applications and services that require high-speed, low-latency, and highly reliable wireless connections have emerged. For example, intelligent manufacturing, smart homes, VR / AR / XR, and industrial Internet 4.0, etc. To meet the wireless communication requirements in these emerging scenarios, relevant standardization organizations or groups have developed new wireless short-range communication system standards to provide wireless transmission capabilities that meet short-range service requirements. The currently developed short-range wireless communication system standards include the basic version that supports ultra-low latency (Sparklink Basic, SLB) and the low-power version that supports low-power transmission (SparkLink Low-Energy, SLE). To meet the need for higher-rate data transmission, currently, consideration is being given to formulating an air interface transmission protocol standard that supports the millimeter-wave frequency band (mmWave) based on the basic version (SLB), including a new physical layer frame structure and various new transmission technologies, etc. However, if millimeter-wave is supported for data transmission, the backward compatibility issue of the wireless communication system applying the short-range wireless communication system standard needs to be considered.

[0237] To expand the wireless application scenarios that serve multiple scenarios and multiple frequency bands, it is necessary to expand the support for new frequency bands and some new functions in the existing wireless communication systems applying the short-range wireless communication system standard. For example, taking the SLB basic version as an illustration, to achieve Figure 9As shown in the figure, on the one hand, data transmission through the low-frequency band can provide basic coverage within the domain, enabling the transmission of system broadcast messages, control messages, and data with relatively low data rates. On the other hand, SLB-mmWave, i.e., high-frequency band transmission, can provide higher data rate transmission through nodes with corresponding millimeter-wave transmission capabilities.

[0238] Similar technologies have been discussed in 3GPP LTE / NR. For example, Carrier Aggregation (CA), Intra-band continuous component carriers (Intra-bandCCs), Intra-band non-continuous component carriers (Intra-bandNC-CCs), and Inter-band CCs can obtain a larger transmission bandwidth by combining multiple subcarriers, thereby achieving a higher peak data rate. The standard also defines relevant aspects in Radio Resource Control (RRC), Media Access Control Control Element (MAC CE), and Data Center Interconnect (DCI), mainly to support the physical layer data scheduling of the secondary cell operating on the secondary component carrier (SCC) by the primary cell operating on the primary component carrier (PCC). However, the cross-carrier scheduling involved in this application (scheduling millimeter-wave carriers on low-frequency carriers) has the following differences in implementation and purpose:

[0239] 1) The particularity of the wireless short-range communication system standard;

[0240] Currently, the wireless short-range communication system standard has defined a complete air interface standard (including the physical layer, media access layer, and link management layer) in the unlicensed low-frequency band to support efficient, low-latency, and highly reliable transmission of wireless short-range communication. The 3GPP protocol mainly focuses on communication among multiple terminals, multiple device manufacturers, and multiple operators in the licensed band, supporting roaming, mobility management, and flexible scheduling strategies. Therefore, the wireless short-range communication system standard is relatively simpler than the 3GPP protocol, only requiring relevant capabilities for supporting wireless transmission without complex control plane signaling.

[0241] 2) Beam management in the high-frequency band of the wireless short-range communication system;

[0242] In terms of supporting beam management in the high-frequency band, 3GPP is mainly based on the correspondence between beams and CSI-RS resources, and the overall framework is completed within the traditional CSI reporting framework of 3GPP; currently, wireless short-range communication systems, such as the SparkLink system, do not involve relevant beam management protocols.

[0243] 3) The wireless short-range communication system operates in the unlicensed band;

[0244] Since the wireless short-range communication system operates in the unlicensed band, the ability to avoid interference in the environment needs to be strengthened in wireless link management. Therefore, the measurement interaction in the designed wireless link management needs to consider effective interference detection and feedback mechanisms. 3GPP LTE / NR has not considered fast detection and avoidance schemes for interference coordination.

[0245] Therefore, different from the carrier aggregation technology in 3GPP LTE / NR, this application mainly aims to support the newly introduced high-frequency band (millimeter wave) transmission in the wireless short-range communication system standard, enhance the existing wireless short-range communication system, and implement the beam management function for high-frequency band transmission in the low-frequency band, including adding an indication of the ability to support millimeter wave transmission in the system broadcast message, adding a request and sending of millimeter wave transmission-related configuration messages during the access process, adding millimeter wave data transmission control messages in the physical layer control information, adding millimeter wave link management-related signaling in the link layer management-related messages, and giving an interaction scheme for nodes to support millimeter wave transmission based on the designed signaling, so as to achieve the purpose of the wireless short-range communication system efficiently supporting multi-band transmission.

[0246] Next, taking the SparkLink system as an example, a design of a short-range wireless communication system supporting multi-band transmission applied to the wireless short-range communication system is introduced.

[0247] I. Indication of the millimeter wave transmission ability of the G node

[0248] The G node (i.e., the second device above) adds an indication signaling for supporting millimeter wave band transmission and millimeter wave transmission-related configuration information in the system broadcast message, and this management node broadcasts and sends it to the domain coverage range in the periodically sent system message.

[0249] As Figure 5 shown, the specific implementation method is as follows:

[0250] S306 can be described as: The G node broadcasts an indication signaling of whether it supports the millimeter wave transmission ability.

[0251] During implementation, an unlicensed frequency band with a low frequency is used in the corresponding physical layer protocol, and an indication signaling supporting millimeter-wave transmission capability is transmitted in a broadcast manner, where the indication signaling supporting millimeter-wave transmission capability can use 1 bit to identify whether millimeter-wave transmission is supported, as follows:

[0252] 1 bit: Identifies whether the system supports millimeter-wave transmission. 0 indicates not supported, and 1 indicates supported.

[0253] In this way, after the T node (i.e., the above-mentioned first device) receives the broadcast information, it determines whether the management node in the domain supports millimeter-wave band transmission through this bit.

[0254] S307 can be described as: The G node transmits configuration information related to G node millimeter-wave transmission.

[0255] The millimeter-wave transmission related configuration information (i.e., the millimeter-wave transmission configuration information of the above-mentioned second device) broadcast by the G node can be understood as capability information about millimeter waves, including but not limited to the following:

[0256] ① Supported millimeter-wave band information, including the millimeter-wave center frequency point position and the number of sub-bands;

[0257] ② The number of antenna transmit ports that digital domain beamforming can support;

[0258] ③ The number of transmit and receive beams that analog domain beamforming can support;

[0259] In this way, after the T node in the domain that supports millimeter-wave transmission receives the indication instruction that the domain can support millimeter-wave transmission, it will automatically receive the millimeter-wave transmission related configuration information broadcast by the G node, or can also obtain it by sending a request for the millimeter-wave transmission configuration information of the relevant domain in the subsequent information. See the description in the following part about the request and sending of millimeter-wave transmission related configuration messages.

[0260] II. Request and Sending of Millimeter-Wave Transmission Related Configuration Messages

[0261] After the T node obtains that the domain can support millimeter-wave transmission through the system broadcast message, it needs to further obtain the relevant configuration information of millimeter-wave transmission and send the configuration information of the T node's millimeter-wave transmission to the G node. The basic process is as Figure 6 shown.

[0262] S303 can be described as: The T node sends a query request for domain millimeter-wave transmission related configuration information (i.e., the above-mentioned first millimeter-wave configuration query information) to the G node.

[0263] Here, after the T node accesses the domain and obtains that the domain can support millimeter-wave transmission, it sends a query request for millimeter-wave transmission-related configuration to the G node. This query request can be transmitted in a link establishment-related message, such as in a T-link dedicated control message. Among them, the T-link dedicated control message refers to the dedicated control signaling transmitted through the T-link, and these messages are used to manage the connection, resource allocation, load balancing, and other key functions between the T node and the G node.

[0264] S301 can be described as: The G node sends the millimeter-wave transmission-related configuration information of this domain to the T node.

[0265] S308 can be described as: The T node sends the indication information on whether the T node supports millimeter-wave transmission ability to the G node.

[0266] Here, the T node can send the indication information on whether the T node supports millimeter-wave transmission ability to the G node, and this information can be reported as part of the device capabilities after the device accesses the system. In addition, considering that only the T node with the ability to support millimeter-wave transmission implements the above S303, therefore, as an optional step, it can be considered that the T node sending this request in S303 has the ability of millimeter-wave transmission.

[0267] S304 can be described as: The G node sends a query application for the device millimeter-wave transmission-related configuration information (i.e., the above-mentioned second millimeter-wave configuration query information) to the T node.

[0268] S305 can be described as: The T node sends the device millimeter-wave transmission-related configuration information to the G node.

[0269] Here, the T node feeds back the device millimeter-wave transmission-related configuration information to the G node, including but not limited to the following:

[0270] ① The supported millimeter-wave frequency band information, including the millimeter-wave center frequency point position and the number of sub-bands;

[0271] ② The number of antenna transmit ports supported by digital domain beamforming;

[0272] ③ The number of transmit and receive beams supported by analog domain beamforming;

[0273] After the G node and the T node exchange their respective millimeter-wave transmission-related configurations, they can select and configure an appropriate transmission format for data transmission in subsequent millimeter-wave-based transmissions based on the millimeter-wave transmission-related configurations.

[0274] III. Millimeter-Wave Data Transmission Control Message

[0275] The data transmission format for transmission on millimeter wave is indicated by the first transmission control information (i.e., the above-mentioned first control information) in the low frequency band, including the time of data transmission, frequency, and beam-related resource indication, etc. Among them, the first transmission control information can be used to directly indicate the data transmission format in the millimeter wave band, such as Figure 7A shown; or, the first transmission control information can be used to directly indicate the second transmission control information (i.e., the above-mentioned second control information) in the millimeter wave band, such as Figure 7B shown.

[0276] IV. Signaling Related to Millimeter Wave Link Management

[0277] Regarding the signaling interaction process related to link management in the millimeter wave band, as Figure 8 shown, it includes millimeter wave link establishment, millimeter wave link performance measurement request, millimeter wave link performance measurement feedback, and millimeter wave link disconnection, etc.

[0278] S309 can be described as: Establish a millimeter wave link between the T node and the G node.

[0279] It should be noted that this application does not limit the specific process of the link establishment process, and any implementable link establishment method can be applied in this application.

[0280] S310 can be described as: The G node sends a millimeter wave link performance measurement request to the T node.

[0281] Here, after establishing the millimeter wave transmission link between the G node and the T node, the G node can request the T node to perform necessary measurements and report the measurement results to the G node. Among them, the configuration information related to the measurement and reporting of the millimeter wave link can be implemented by setting in the measurement report configuration information (measreportConfig).

[0282] In this application, the measurement of the millimeter wave link is mainly for the signal quality measurement using different analog beamforming, so the following configuration information is required: the port number of the antenna transmission port used for the measurement reference signal and the analog transceiver beam ID number used, the result type of the reference signal reception quality value of layer 1 for which the device node feeds back the measurement, and the corresponding quantization configuration, and this configuration information is sent to the T node through the millimeter wave link performance measurement request.

[0283] S313 can be described as: The T node sends the millimeter wave link performance measurement result to the G node.

[0284] After S313, S314 can also be included: Release the millimeter wave link between the T node and the G node.

[0285] Here, when the link quality is insufficient to meet the transmission requirements, the millimeter-wave transmission link is released, and data is transmitted in the low-frequency transmission mode.

[0286] In a fourth aspect, to implement the above wireless communication method, an apparatus 1000 (a first apparatus or a second apparatus) according to an embodiment of the present application, as Figure 10 shown, may include at least one processor 1001 (a first processor or a second processor) and at least one transceiver 1002 (a first transceiver or a second transceiver) coupled to the at least one processor 1001. The transceiver 1002 may include at least two separate receiving circuit systems and transmitting circuit systems, or at least two integrated receiving circuit systems and transmitting circuit systems. The at least one processor 1001 may be a central processing unit (CPU), a microprocessor unit (MPU), a digital signal processor (DSP), or a field-programmable gate array (FPGA), etc.

[0287] It should be noted that since the transceiver 1002 may include at least two separate receiving circuit systems and transmitting circuit systems, or at least two integrated receiving circuit systems and transmitting circuit systems, the reason is that the transceiver in the present application can support both the millimeter-wave band and the unlicensed band at the same time. However, the millimeter-wave band and the unlicensed band correspond to different frequency ranges. Therefore, the circuits or devices used to implement millimeter-wave band transmission in the first transceiver and the second transceiver are different from the circuits or devices used to implement unlicensed band transmission.
