[0051] The following is a detailed introduction to a beam management method and device provided by the present disclosure with reference to the accompanying drawings.

[0052] Please refer to Figure 2, which is a flowchart of a beam management method provided by an embodiment of the present disclosure.

[0053] As shown in FIG2 , the method is executed by a network-side device, and the method may include but is not limited to the following steps:

[0054] S21: Send a reference signal for beam measurement and configuration information corresponding to the reference signal to the terminal device.

[0055] In an embodiment of the present disclosure, a network-side device may send a reference signal for beam measurement to a terminal device, wherein one or more reference signals may correspond to one beam.

[0056] In an embodiment of the present disclosure, a network-side device may send configuration information corresponding to a reference signal to a terminal device to distinguish different reference signals based on different configuration information. The configuration information corresponding to the reference signal may include an index, for example, adding an index to each reference signal, or the configuration information corresponding to the reference signal may further include a code, for example, adding a code to each reference signal, or the configuration information corresponding to the reference signal may further include an index of the time-frequency domain resources occupied by the reference signal, for example, adding an index to the time-frequency domain resources occupied by each reference signal, and so on.

[0057] Of course, the above examples are for illustration only. The configuration information corresponding to the reference signal may also include other information. When it is possible to distinguish different reference signals according to different configuration information, it can be set as needed. The embodiments of the present disclosure do not impose specific restrictions on this.

[0058] It should be noted that the network side device can send the reference signal used for beam measurement and the configuration information corresponding to the reference signal to the terminal device at the same time, or it can send them separately, for example, first send the configuration information corresponding to the reference signal to the terminal device, and then send the reference signal for beam measurement, or vice versa.

[0059] Among them, in the case of separate transmission, the reference signals for beam measurement and the configuration information corresponding to the reference signals sent successively can be based on different specific conditions respectively, and the corresponding information can be sent when the corresponding specific conditions are met.

[0060] It can be understood that when the configuration information corresponding to the reference signal is first sent to the terminal device and the reference signal for beam measurement is then sent, the configuration information corresponding to the reference signal sent first may include but is not limited to the configuration information corresponding to the reference signal for beam measurement sent later, and may also include configuration information corresponding to other reference signals.

[0061] In some embodiments, the configuration information includes at least one of the following:

Alternatively, the coding of the reference signal, the reference signal index and / or the index of a time-frequency resource occupied by the reference signal may be pre-configured for the terminal device, and then the reference signal coding, the reference signal index and / or the index of a time-frequency resource occupied by the reference signal may be sent to the terminal device, so that the terminal device can determine the reference signal and the configuration information corresponding to the reference signal.

[0068] S22: Receive beam quality indication information reported by the terminal device, where the beam quality indication information includes a measurement quantity and reference signal information corresponding to the measurement quantity, and the reference signal information is determined by the terminal device according to configuration information.

[0069] In an embodiment of the present disclosure, a terminal device receives a reference signal for beam measurement sent by a network-side device, as well as configuration information corresponding to the reference signal, measures the reference signal to obtain a measurement quantity, and further reports beam quality indication information to the network-side device. The beam quality indication information includes the measurement quantity and reference signal information corresponding to the measurement quantity.

[0070] Among them, the reference signal information reported by the terminal device is determined according to the configuration information, and the configuration information indicates different reference signals.

[0071] It can be understood that the beam quality indication information reported by the terminal device includes the measurement quantity and the reference signal information corresponding to the measurement quantity. One or more reference signals can be used to measure a beam. When the beam quality indication information reported by the terminal device includes the measurement quantity and the reference signal information corresponding to the measurement quantity, more precise beam measurement can be achieved, thereby realizing beam measurement alignment of a narrow beam.

[0072] On this basis, when the beam quality indication information reported by the terminal device includes the measurement quantity and the reference signal information corresponding to the measurement quantity, since the network side device can obtain the measurement quantity corresponding to the reference signal, the network side device can measure the measurement results of each reference signal of different beams, making it easier to measure the beam quality and accelerate the beam selection process, thereby determining the beam direction more quickly to achieve more efficient beam measurement and tracking.

[0073] In some embodiments, the measured quantity includes at least one of the following:

[0074] Reference signal received power RSRP;

[0075] Reference signal received quality RSRQ;

[0096] In some embodiments, the network side device sends location configuration information to the terminal device, where the location configuration information is used to indicate the regional location.

[0097] In the embodiment of the present disclosure, the network side device may pre-define the regional location and configure the defined regional location to the terminal device, and indicate the regional location by sending location configuration information to the terminal device.

[0100] Please refer to Figure 3, which is a flowchart of another beam management method provided by an embodiment of the present disclosure.

[0101] As shown in FIG3 , the method is executed by a network-side device, and the method may include but is not limited to the following steps:

[0102] S31: Send a reference signal for beam measurement and configuration information corresponding to the reference signal to the terminal device.

[0103] S32: Receive beam quality indication information reported by the terminal device, where the beam quality indication information includes a measurement quantity and reference signal information corresponding to the measurement quantity, and the reference signal information is determined by the terminal device according to configuration information.

[0104] In the embodiment of the present disclosure, the relevant description of S31 and S32 can refer to the relevant description in the above embodiment, and the same content will not be repeated here.

[0105] S33: Send indication information to the terminal device, where the indication information is used to indicate beam information, and the location corresponding to the beam information or the location area to which it belongs.

[0106] In the disclosed embodiments, a network device sends a reference signal for beam measurement, along with configuration information corresponding to the reference signal, to a terminal device, and receives beam quality indication information reported by the terminal device. The beam quality indication information includes a measurement value and the reference signal information corresponding to the measurement value. This allows for rapid determination of beam range, enabling more efficient beam measurement and tracking.

[0107] Based on this, the network side device can obtain the beam quality according to the measurement quantity corresponding to the reference signal, and then send indication information to the terminal device to indicate the beam information and the position corresponding to the beam information or the position area to which it belongs.

[0108] After receiving instructions from the network-side device, the terminal device can perform beam selection, choosing the receive beam for receiving downlink signals and the uplink beam for sending uplink signals. This enables more efficient beam tracking based on efficient beam measurement.

[0109] In some embodiments, the indication information includes at least one of the following:

[0110] Regional beam sequence;

[0111] Beam formula parameters.

[0112] In an embodiment of the present disclosure, a network side device sends indication information to a terminal device, wherein the indication information is used to indicate beam information, and a position corresponding to the beam information or a location area to which the beam information belongs. A regional beam sequence can be sent to the terminal device to indicate the beam information, and a position corresponding to the beam information or a location area to which the beam information belongs.

[0113] In some embodiments, the regional beam sequence includes the location or the regional number of the location region to which it belongs, and the beam index corresponding to the regional number or the reference signal index associated with the beam.

[0114] In an embodiment of the present disclosure, a network side device sends a regional beam sequence to a terminal device to indicate beam information and the position corresponding to the beam information or the location area to which it belongs. The regional beam sequence includes the area number of the position or the location area to which it belongs, and the beam index corresponding to the area number.

[0119] In the embodiment of the present disclosure, the network side device sends indication information to the terminal device, wherein the indication information is used to indicate the beam information and the location or location area corresponding to the beam information. The regional beam formula parameters can be sent to the terminal device, such as: multiplication coefficients: k1, k2...k M .

[0120] The terminal device receives the regional beam formula parameters sent by the network side device, multiplication coefficients: k1, k2...k M After that, the beam index f of the nth position or the position area to which it belongs can be determined. (n) =k1f (n-1) +k2f (n-2) ...+k M f (n-M) , where n and M are integers.

[0121] Therefore, when the terminal device determines its own location or the location area to which it belongs, it can determine the beam index and further determine the beam.

[0256] S81: Send the area location to the network side device.

[0257] In the disclosed embodiments, a terminal device may report location information to a network device, including a regional location. The regional location may be a certain area agreed upon with the network device. For example, based on a protocol agreement, the beam coverage range of the network device may be divided into different regions, so that the terminal device can determine its regional location based on the protocol agreement and report it. For another example, the network device may divide its beam coverage range into different regions and assign the regional divisions to the terminal device, so that the terminal device can determine its regional location and report it.

[0258] In some embodiments, the terminal device determines the regional location based on protocol agreement or location configuration information sent by the network side device.

[0259] In the embodiment of the present disclosure, the terminal device may determine the regional location based on a protocol agreement, or determine the regional location based on location configuration information sent or configured by a network-side device.

[0260] In the disclosed embodiments, the network device can pre-define a regional location and configure the defined regional location to the terminal device, thereby indicating the regional location by sending location configuration information to the terminal device. Thus, the terminal device can determine the regional location based on the location configuration information sent by the network device and report the regional location to the network device.

[0261] S82: Receive indication information sent by the network side device, where the indication information is used to indicate beam information, and the location corresponding to the beam information or the location area to which it belongs.

[0262] In the disclosed embodiments, upon receiving a regional location reported by a terminal device, the network device can send an indication to the terminal device, indicating beam information and the location or location area to which the beam information corresponds. The terminal device can then select a beam based on the indication sent by the network device, for example, selecting a receive beam for receiving downlink signals and an uplink beam for transmitting uplink signals. This enables more efficient real-time beam tracking and updates based on spatial location.
