Description

Beam management method and device Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a beam management method, apparatus, device, and storage medium. Background Art

[0002] In communication systems, beam-based transmission and reception are required to ensure the coverage of new radio (NR) technologies due to the rapid attenuation of high-frequency channels.

[0114] With the rapid development of communications technology, millimeter wave communications have become a key technology for the new radio (NR) interface of fifth-generation mobile communication technology (5G). As low-frequency wireless spectrum resources are depleted, the development and utilization of high-frequency millimeter wave and even terahertz communication technologies have become an inevitable trend.

[0115] Furthermore, in one embodiment of the present disclosure, regarding spectrum allocation for terahertz wireless communications, the International Telecommunication Union (ITU) has completed frequency divisions for various frequency-using services within the 100-275 GHz frequency range. Of this, 97.2 GHz of globally uniformly identified spectrum is allocated for land mobile and fixed services. At the 2019 World Radiocommunication Conference (WRC-19), four new globally identified mobile service bands were added within the 275-450 GHz frequency range for land mobile and fixed services: 275-296 GHz, 306-313 GHz, 318-333 GHz, and 356-450 GHz. The total newly added spectrum bandwidth is 137 GHz.

[0116] With the development of communication technology, a terahertz communication task force can be established to promote the work of wireless technology. Terahertz communication will be considered as an important candidate technology for the sixth generation wireless systems (6G) communication. The task force will study and discuss key technologies, application visions and standardization of terahertz communication. This will lay the foundation for research and industry consensus for terahertz communication to enter the International Mobile Telecommunications (IMT) technical standards.

[0117] The following describes in detail a beam management method, apparatus, device, and storage medium provided by embodiments of the present disclosure with reference to the accompanying drawings.

[0118] FIG1 is a flow chart of a beam management method provided by an embodiment of the present disclosure. The method is executed by a network-side device. As shown in FIG1 , the method may include the following steps:

[0119] Step 101: Based on the frequency band information of the measurement reference signal, a beam corresponding to the frequency band information is used to send the measurement reference signal to a terminal device.

[0120] It should be noted that, in one embodiment of the present disclosure, a terminal device may refer to a device that provides voice and / or data connectivity to a user. The terminal device may communicate with one or more core networks via a RAN (Radio Access Network). The terminal device may be an IoT terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal.

For example, a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, or a user agent. Alternatively, the terminal device may be a device of an unmanned aerial vehicle.

Alternatively, the terminal device may also be a roadside device, for example, a street lamp, a traffic light or other roadside device with wireless communication function.

[0121] In one embodiment of the present disclosure, the present disclosure can be applied to millimeter wave communication or terahertz communication scenarios.

[0122] Furthermore, in one embodiment of the present disclosure, based on the frequency band information of the sounding reference signal, transmitting the sounding reference signal to the terminal device using a beam corresponding to the frequency band information includes at least one of the following:

[0123] If the frequency band information of the measurement reference signal is low frequency band information, a wide beam is preferentially used to send the measurement reference signal to the terminal device;

[0124] If the frequency band information of the measurement reference signal is high frequency band information, a narrow beam is preferentially used to send the measurement reference signal to the terminal device.

[0125] And, in one embodiment of the present disclosure, the method further includes:

[0126] Sending first signaling to the terminal device, wherein the first signaling includes configuration information of the measurement reference signal.

[0127] And, in one embodiment of the present disclosure, the configuration information includes at least one of the following:

[0129] Configuration information of resource blocks or subcarriers occupied by measurement reference signals;

[0130] Configuration information of antenna ports occupied by measurement reference signals;

[0131] Configuration information of the time-frequency resource locations occupied by measurement reference signals;

[0132] Configuration information of generation parameters of measurement reference signal sequences.

[0133] And, in one embodiment of the present disclosure, the method further includes:

[0134] Send a second signaling to the terminal device, wherein the second signaling includes reporting configuration information of the measurement reference signal.

[0135] Furthermore, in one embodiment of the present disclosure, the reported configuration information includes at least one of the following:

[0136] Beam measurement information;

[0137] Reporting condition information for beam measurement;

[0138] Beam measurement reporting period information.

[0139] And, in one embodiment of the present disclosure, the method further includes:

[0140] The receiving terminal device reports beam quality indication information for the measurement reference signal.

[0141] Furthermore, in one embodiment of the present disclosure, the beam quality indication information includes at least one of the following:

[0142] Indication information of the measurement reference signal corresponding to the beam;

[0143] Measurement information of beam quality.

[0144] For example, in one embodiment of the present disclosure, the indication information of the sounding reference signal corresponding to the beam includes at least one of the following:

[0145] Indication information of the frequency band occupied by the measurement reference signal;

[0146] Indication information of resource blocks or subcarriers occupied by measurement reference signals;

[0147] Indication information of antenna ports occupied by measurement reference signals;

[0148] Indication information of the time-frequency resources occupied by the measurement reference signal.

[0149] For example, in one embodiment of the present disclosure, the measurement information of the beam quality includes at least one of a reference signal received power RSRR, a reference signal received quality RSRQ, and a signal to interference and noise ratio SINR.

[0150] For example, in one embodiment of the present disclosure, the method further includes:

[0151] Send a third signaling to the terminal device, wherein the third signaling includes beam indication information, and the beam indication information is used to indicate the beam used for the data channel and the demodulation reference signal.

[0152] For example, in one embodiment of the present disclosure, the beam indication information includes at least one of the following:

[0153] Beam indication information for the index of the used beam;

[0154] Beam indication information for the measurement reference signal associated with the used beam.

[0155] In summary, in the embodiment of the present disclosure, based on the frequency band information of the measurement reference signal, a beam corresponding to the frequency band information is used to send the measurement reference signal to the terminal device. In the embodiment of the present disclosure, since the beam corresponds to the frequency band information, the effectiveness of the measurement reference signal transmission can be improved, and the situation where the measurement reference signal does not match the beam management range, resulting in poor beam management accuracy, can be reduced, and the accuracy of beam quality measurement can be improved. The present disclosure provides a processing method for a "beam management" scenario to provide the frequency band information of the measurement reference signal, use a measurement reference signal transmission scheme that combines high and low frequency bands, improve the effectiveness of the measurement reference signal transmission, and thereby improve the accuracy of the beam quality measurement.

[0156] For example, when the network-side device executes the frequency band information based on the measurement reference signal and uses a beam corresponding to the frequency band information to send the measurement reference signal to the terminal device, at least one of the following may be included:

[0157] If the frequency band information of the measurement reference signal is low frequency band information, a wide beam is preferentially used to send the measurement reference signal to the terminal device;

[0158] If the frequency band information of the measurement reference signal is high frequency band information, a narrow beam is preferentially used to send the measurement reference signal to the terminal device.

[0159] In one embodiment of the present disclosure, a network device may configure frequency band information for a measurement reference signal. If the frequency band information for the measurement reference signal is low-frequency band information, the network device may preferentially use a wide beam to transmit the measurement reference signal to the terminal device. The measurement reference signal transmitted using the wide beam is used for coarse beam tracking. Different beams correspond to different measurement periods.

[0160] For example, in one embodiment of the present disclosure, when the frequency band information of the measurement reference signal is 6 GHz, the network device may preferentially use a wide beam to transmit the measurement reference signal to the terminal device. For example, when the network device uses a wide beam to transmit the measurement reference signal to perform beam traversal of the cell coverage area, fewer beams need to be transmitted, thereby reducing the beam traversal time for the entire cell coverage area.

[0161] In one embodiment of the present disclosure, a network device may configure frequency band information for a measurement reference signal. If the frequency band information for the measurement reference signal is a high frequency band, the network device may preferentially use a narrow beam to transmit the measurement reference signal to the terminal device. The measurement reference signal transmitted using the narrow beam is used for fine beam tracking.

[0162] In summary, in the embodiments of the present disclosure, based on the frequency band information of the measurement reference signal, a beam corresponding to the frequency band information is used to send the measurement reference signal to the terminal device. In the embodiments of the present disclosure, it is specifically described that when the frequency band information of the measurement reference signal is low frequency band information, a wide beam is preferentially used to send the measurement reference signal to the terminal device, and when the frequency band information of the measurement reference signal is high frequency band information, a narrow beam is preferentially used to send the measurement reference signal to the terminal device. Since the beam corresponds to the frequency band information, the beam measurement quality and the beam measurement efficiency can be balanced, the effectiveness of the measurement reference signal transmission can be improved, the situation where the measurement reference signal does not match the beam management range, resulting in poor beam management accuracy, can be reduced, and the accuracy of beam quality measurement can be improved. The present disclosure provides a processing method for a "beam management" scenario to provide the frequency band information of the measurement reference signal, use a measurement reference signal sending scheme that combines high and low frequency bands, improve the effectiveness of the measurement reference signal transmission, and thereby improve the accuracy of the beam quality measurement.

[0164] Step 201: Send a first signaling to a terminal device, where the first signaling includes configuration information of a measurement reference signal.

[0165] In one embodiment of the present disclosure, the first signaling refers to signaling used to transmit configuration information for a sounding reference signal. The "first" in the first signaling is used only to distinguish it from other signalings, and the first signaling does not specifically refer to a fixed signaling. For example, when the configuration information for the sounding reference signal changes, the first signaling may also change accordingly. For example, when the transmission time of the first signaling changes, the first signaling may also change accordingly.

[0166] In one embodiment of the present disclosure, the configuration information includes at least one of the following:

[0167] Configuration information of the frequency band occupied by the measurement reference signal;

The present disclosure provides a processing method for a "beam management" scenario to provide configuration information of a measurement reference signal, use a measurement reference signal sending scheme that combines high and low frequency bands, improve the effectiveness of measurement reference signal sending, and thereby improve the accuracy of beam quality measurement.

The "second" in the second signaling is used only to distinguish it from other signalings, and the second signaling does not specifically refer to a fixed signaling. For example, when the reporting configuration information for the measurement reference signal changes, the second signaling may also change accordingly.

For example, when the amount of information included in the reported configuration information changes, the reported configuration information may also change accordingly.

[0181] Furthermore, in one embodiment of the present disclosure, measurement information indicates a beam measurement quantity, i.e., specific measurement information when measuring a beam. This measurement information does not specifically refer to fixed measurement information. For example, if at least one measurement quantity corresponding to the measurement information changes, the measurement information may also change accordingly.

[0182] Furthermore, in one embodiment of the present disclosure, the reporting condition information of the beam measurement is used to indicate the conditions under which the terminal device reports the beam quality indication information.

[0183] In summary, in the embodiment of the present disclosure, a second signaling is sent to the terminal device, wherein the second signaling includes reporting configuration information of the measurement reference signal. In the embodiment of the present disclosure, by sending the reporting configuration information of the measurement reference signal to the terminal device, the situation in which the measurement reference signal does not match the beam management range, resulting in poor beam management accuracy, can be reduced, and the accuracy of beam measurement quality reporting can be improved. The present disclosure provides a processing method for a "beam management" scenario to provide configuration information of the measurement reference signal, use a measurement reference signal sending scheme that combines high and low frequency bands, improve the effectiveness of measurement reference signal sending, and thereby improve the accuracy of beam quality measurement.
