Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technology but is not limited to the field of wireless communication technology, and in particular to a beam scanning method, apparatus, communication equipment, and storage medium. Background Art

[0002] With the development of mobile communication technology, high-frequency communication is becoming an increasingly important trend in wireless communication to meet higher data rates. For example, millimeter waves have been introduced in the fifth-generation mobile communication technology, New Radio (NR), and terahertz frequency bands are also expected to be widely used in mobile communication technology.

[0003] Beam splitting occurs in high-frequency communications, particularly those in the terahertz band. This occurs because antenna modules are designed based on the center frequency. Terahertz communications typically support bandwidths of several or even tens of GHz. Consequently, at frequencies far from the center frequency, the beam direction corresponding to these frequencies deviates from the beam corresponding to the center frequency due to phase shifts, resulting in beam splitting.

[0019] processor;

[0020] a memory for storing instructions executable by the processor;

[0021] The processor is configured to implement the method described in any embodiment of the present disclosure when running the executable instructions.

[0022] According to a sixth aspect of an embodiment of the present disclosure, a computer storage medium is provided, wherein the computer storage medium stores a computer executable program, and when the executable program is executed by a processor, the method described in any embodiment of the present disclosure is implemented.

[0023] In an embodiment of the present disclosure, a base station receives resource configuration information sent based on the beam splitting capability of the terminal; wherein the resource configuration information is used for the terminal to determine resources for beam scanning using the beam splitting beam. In this way, on the one hand, since the base station sends the resource configuration information based on the beam splitting capability of the terminal, the resource configuration can adapt to the capability of the terminal. On the other hand, the terminal can use the beam splitting beam to perform beam scanning on the resources indicated by the resource configuration information. Here, since the terminal can use multiple beams of beam splitting to perform beam scanning, the efficiency of the terminal in performing beam scanning will be higher compared to the method in which the terminal can only use a single beam to perform beam scanning.

[0058] To facilitate understanding by those skilled in the art, the embodiments of the present disclosure list multiple implementation methods to clearly illustrate the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in the embodiments of the present disclosure can be implemented individually, or can be implemented together with the methods of other embodiments in the embodiments of the present disclosure, or can be implemented together with some methods in other related technologies individually or in combination; the embodiments of the present disclosure do not limit this.

[0059] In order to better understand the technical solution described in any embodiment of the present disclosure, first, a wireless communication scenario is described through an embodiment.

[0060] In one embodiment, see Figure 2 The antenna module is designed based on the center frequency f0. In terahertz communications, the supported bandwidth typically reaches several GHz or even tens of GHz. Consequently, at frequencies far from the center frequency, the beam direction corresponding to these frequencies will deviate from the beam corresponding to the center frequency due to phase shifts, resulting in beam splitting.

[0061] Here, see Figure 3 The beam splitting phenomenon will cause the gain of the beam in the frequency band far away from the center frequency to decrease, thus causing the performance of the entire system to deteriorate. Therefore, it is necessary to reduce the beam splitting phenomenon.

[0062] In one embodiment, additional phase delay is introduced to reduce beam splitting or adjust the split beam to a desired direction. However, beam splitting can also bring certain benefits. For example, during beam scanning, the split beam can be used to scan to improve beam scanning efficiency.

[0063] like Figure 4 As shown, this embodiment provides a beam scanning method, which is applied to a terminal and includes:

[0064] Step 41: receiving resource configuration information sent by the base station according to the beam splitting capability of the terminal;

[0065] The resource configuration information is used for the terminal to determine resources for beam scanning using beam splitting.

[0066] Here, the terminal can be but is not limited to a mobile phone, a wearable device, a vehicle-mounted terminal, a roadside unit (RSU), a smart home terminal, an industrial sensor device, and other terminals.

[0067] Here, a base station can be an access device for a terminal to access a network. The base station can be of various types. For example, a base station of a third-generation mobile communication (3G) network, a base station of a fourth-generation mobile communication (4G) network, a base station of a fifth-generation mobile communication (5G) network, or a base station of any generation of communication system.

[0068] In one embodiment, the resource configuration information is used for the terminal to determine resources for beam scanning of neighboring cells using beams obtained through beam splitting; wherein the neighboring cells are cells adjacent to the serving cell.

[0069] In one embodiment, while conducting wireless communications in a serving cell, a terminal scans neighboring cells to obtain the radio channel quality of signals on the neighboring cell's beam. After obtaining the radio channel quality measurement results, the terminal transmits the measurement results to the base station. In this way, in response to the radio channel quality of the serving cell falling below a quality threshold, a cell handover can be performed based on the radio channel quality of the neighboring cell.

[0070] In another embodiment scenario, a base station transmits wireless signals using beams in different directions. A terminal measures the quality of the wireless channels transmitted by the base station using beams in different directions using the beams in different directions. After obtaining the measurement results of the wireless channel quality, the terminal reports the measurement information to the base station. The base station determines the transmit beam for data transmission based on the reported information. Here, beam scanning of neighboring cells can be performed by measuring the wireless signals transmitted by the base station using beams.

[0071] In one embodiment, the resource configuration information is used for the terminal to determine resources for performing adjacent beam scanning using a beam splitted by the beam; wherein the adjacent beam is a beam adjacent to the serving beam.

[0072] In one embodiment, a serving base station transmits multiple beams; a beam used for wireless communication between the serving base station and a terminal is a serving beam; and beams adjacent to the serving beam in the multiple beams are adjacent beams of the serving beam. The configured resources indicate resources for performing adjacent beam scanning of the serving beam using beams generated by beam splitting.

[0073] In one embodiment, when a terminal uses a serving beam to communicate wirelessly with a base station, it scans the radio channel quality of adjacent beams. After obtaining a measurement of the radio channel quality, the terminal sends the measurement result to the base station. In this way, if the radio channel quality of the serving beam falls below a quality threshold, a cell handover can be performed based on the radio channel quality of the adjacent beam.

[0074] Here, the wireless channel quality may include at least one of the following: Reference Signal Receiving Power (RSRP) and Reference Signal Receiving Quality (RSRQ).

[0075] In one embodiment, the terminal can perform beam scanning on each of the multiple beams of beam splitting to obtain measurement results on each beam. The base station can configure different resources for different beams. That is, the resource configuration information indicates the resources of the different beams of beam splitting. For example, the beams of beam splitting include beam 1, beam 2, and beam 3, and the configured resources are resource 1, resource 2, and resource 3, respectively. The terminal can perform signal measurement on beam 1, beam 2, and beam 3 on the corresponding resources, respectively, to obtain measurement results on each beam. After the beam scan is completed, the terminal will send the scanning results obtained by scanning each beam to the base station.

[0076] In one embodiment, the terminal sends capability information to the base station; wherein the capability information indicates the beam splitting capability supported by the terminal; in response to the base station receiving the capability information and the capability information indicating that the terminal supports the beam splitting capability, the base station sends resource configuration information to the terminal according to the capability information; the terminal receives the resource configuration information; the terminal performs beam scanning using the beam splitted beam on the resources indicated by the resource configuration information.

[0077] In one embodiment, a terminal sends capability information to a base station, where the capability information indicates beam splitting capabilities supported by the terminal. In response to the base station receiving the capability information and the capability information indicating that the terminal does not support beam splitting capabilities, the base station does not send resource configuration information to the terminal. In this case, the terminal can perform beam scanning based on the predetermined resource configuration.

[0078] In one embodiment, in response to the terminal establishing a Radio Resource Control (RRC) connection with the base station, the terminal sends capability information to the base station, where the capability information at least indicates whether the terminal supports or does not support beam splitting.

[0079] In one embodiment, the capability information includes at least one of the following:

[0080] First information, indicating whether the terminal supports or does not support beam splitting capability;

[0081] Second information indicates a spectrum bandwidth of an effective beam of beam splitting; wherein a difference between a gain of the effective beam and a gain of the center beam is less than or equal to a gain threshold; and the center beam is a beam corresponding to a center frequency point of the beam splitting;

[0082] The third information indicates the number of effective beams;

[0083] The fourth information indicates the frequency domain position relationship between the effective beam and the center beam.

[0084] In one embodiment, in response to a terminal's beam being capable of beam splitting, the first information indicates the terminal's support for beam splitting; in response to a terminal's beam being incapable of beam splitting, the first information indicates the terminal's lack of support for beam splitting. Upon receiving the capability information, the base station may allocate resources to the terminal that supports beam splitting. Here, resources may be allocated to each of the multiple beams of the terminal's beam splitting. The terminal may then perform beam scanning using the multiple beams of the beam splitting on the allocated resources.

[0085] In one embodiment, the beams of the beam splitting include multiple beams. The multiple beams include an effective beam and an ineffective beam. In one embodiment, the difference between the gain of the effective beam and the gain of the center beam is less than or equal to a gain threshold; and the difference between the gain of the ineffective beam and the gain of the center beam is greater than the gain threshold. In another embodiment, the gain of the effective beam is greater than the gain threshold; and the gain of the ineffective beam is less than the gain threshold.

[0086] In one embodiment, the beam gain is a parameter associated with the beam's transmit power. In one embodiment, in response to the beam's transmit power being greater than a power threshold, the beam gain is greater than the gain threshold; in response to the beam's transmit power being less than the power threshold, the beam gain is less than the gain threshold.

[0087] In one embodiment, in response to scanning wireless signals of equal signal strength and the gain of the first effective beam being greater than the gain of the second effective beam, the signal strength of the wireless signal scanned on the first effective beam is greater than the signal strength of the wireless signal scanned on the second effective beam. Here, the first effective beam and the second effective beam are beams of beam splitting.

[0088] In one embodiment, in response to the number of effective beams being greater than a quantity threshold, the spectral bandwidth occupied by the effective beams of beam splitting is greater than a bandwidth threshold; in response to the number of effective beams being less than the quantity threshold, the spectral bandwidth occupied by the effective beams of beam splitting is less than the bandwidth threshold. The base station allocates resources to each effective beam corresponding to this quantity. Here, the spectral bandwidth occupied by the effective beams may be the spectral bandwidth occupied by all effective beams of beam splitting.

[0089] In one embodiment, the beam includes a beam corresponding to a center frequency point and a beam corresponding to an edge position, wherein the gain of the beam corresponding to the center frequency point is greater than the gain of the beam corresponding to the edge position.

[0090] In one embodiment, the effective beam of the beam splitting includes multiple beams; wherein the relative frequency domain position relationship between each effective beam and the central beam is different.

[0091] In one embodiment, the base station determines the beam splitting capability of the terminal based on the type of the terminal; in response to the base station receiving the capability information and the capability information indicating that the terminal supports the beam splitting capability, the base station sends resource configuration information to the terminal based on the beam splitting capability; the terminal receives the resource configuration information; the terminal performs beam scanning using the beam splitted beam on the resources indicated by the resource configuration information.

[0092] In one embodiment, the terminal type includes: a first type that supports beam splitting and a second type that does not support beam splitting. In one embodiment, in response to the terminal type being the first type, it is determined that the terminal supports beam splitting; in response to the terminal type being the second type, it is determined that the terminal does not support beam splitting.

[0093] Here, the resource configuration information may indicate time domain and / or frequency domain resources for beam scanning. In one embodiment, different time domain and / or frequency domain resources are configured for different beams of beam splitting.

[0094] In one embodiment, a base station receives resource configuration information sent based on the beam splitting capability of a terminal. The resource configuration information is used by the terminal to determine resources for beam scanning using an effective beam of beam splitting. Here, the difference between the gain of the effective beam and the gain of the center beam is less than or equal to a gain threshold. The center beam is the beam corresponding to the center frequency of the beam splitting.

[0095] In an embodiment of the present disclosure, a base station receives resource configuration information sent based on the beam splitting capability of a terminal; the resource configuration information is used by the terminal to determine resources for beam scanning using the beam splitting beam. Thus, on the one hand, because the base station sends resource configuration information based on the beam splitting capability of the terminal, the resource configuration can adapt to the capabilities of the terminal. On the other hand, the terminal can use the beam splitting beam to perform beam scanning on the resources indicated by the resource configuration information. Here, because the terminal can use multiple beams of beam splitting to perform beam scanning, the efficiency of the terminal's beam scanning will be higher compared to a method in which the terminal can only use a single beam to scan neighboring cells.

[0096] It should be noted that those skilled in the art will understand that the method provided in the embodiments of the present disclosure may be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0097] like Figure 5 As shown, this embodiment provides a beam scanning method, which is applied to a terminal and includes:

[0098] Step 51: Send capability information to the base station;

[0099] The capability information at least indicates the beam splitting capability supported by the terminal.

[0100] In one embodiment, the terminal may send capability information to the base station in at least one of the following ways:

[0101] The terminal sends capability information to the base station through a random access message in a random access process;

[0102] The terminal sends capability information to other terminals via RRC messages.

[0103] In this way, sending capability information through random access messages and / or RRC messages can improve signaling compatibility.

[0104] In one embodiment, the terminal may send capability information to the base station at at least one of the following times:

[0105] In response to the RRC connection establishment, sending capability information to the base station using an RRC message;

[0106] In response to starting random access, sending capability information to the base station using a first message MSG1;

[0107] In response to receiving the request information for acquiring capability information sent by the base station, the capability information is sent to the base station.

[0108] In one embodiment, in response to the terminal being able to perform beam splitting, it is indicated that the terminal supports the capability of beam splitting; in response to the terminal being unable to perform beam splitting, it is indicated that the terminal does not support the capability of beam splitting.

[0109] In one embodiment, the beam splitting capability of the terminal may be indicated by the information field of the capability information. For example, if the information field of the capability information carries "0", it indicates that the terminal does not support the beam splitting capability; if the information field of the capability information carries "1", it indicates that the terminal supports the beam splitting capability.

[0110] In one embodiment, the capability information includes at least one of the following:

[0111] First information, indicating whether the terminal supports or does not support beam splitting capability;

[0112] Second information indicates a spectrum bandwidth of an effective beam of beam splitting; wherein a difference between a gain of the effective beam and a gain of the center beam is less than or equal to a gain threshold; and the center beam is a beam corresponding to a center frequency point of the beam splitting;

[0113] The third information indicates the number of effective beams;

[0114] The fourth information indicates the frequency domain position relationship between the effective beam and the center beam.

[0115] It should be noted that those skilled in the art will understand that the method provided in the embodiments of the present disclosure may be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0116] like Figure 6 As shown, this embodiment provides a beam scanning method, which is applied to a terminal and includes:

[0117] Step 61: Perform beam scanning on the resources indicated by the resource configuration information using the beam splitting beam.

[0118] In one embodiment, beam scanning is performed using an effective beam of beam splitting on a resource indicated by resource configuration information; wherein there are multiple effective beams of beam splitting, and the resource configuration information indicates a resource for each effective beam. Thus, the terminal can perform beam scanning using the corresponding effective beam on the corresponding resource indicated by the resource configuration information.

[0119] In one embodiment, in response to the service quality of the serving cell of the terminal being less than a quality threshold, beam scanning is performed using beams obtained through beam splitting on the resources indicated by the resource configuration information. This allows the terminal to promptly scan a cell whose signal quality meets the quality requirements and promptly perform cell reselection or cell handover. Alternatively, the terminal can promptly scan a beam whose signal quality meets the quality requirements and promptly perform beam handover.

[0120] In one embodiment, beam scanning is periodically performed using beams of beam splitting on the resources indicated by the resource configuration information. It should be noted that there are multiple beams of beam splitting and beam scanning can be performed using the multiple beams simultaneously.

[0121] It should be noted that those skilled in the art will understand that the method provided in the embodiments of the present disclosure may be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0122] like Figure 7 As shown, this embodiment provides a beam scanning method, which is applied to a terminal and includes:

[0123] Step 71: On the resources indicated by the resource configuration information, beam scanning is performed within a predetermined scanning angle using the beam splitting.

[0124] In one embodiment, the resource configuration information indicates a time unit for beam scanning within a predetermined scanning angle using a beam splitting. Here, the time unit may be a time slot. For example, in a first time slot indicated by the resource configuration information, the terminal uses the beam splitting to perform beam scanning within a first predetermined scanning angle; in a second time slot indicated by the resource configuration information, the terminal uses the beam splitting to perform beam scanning within a second predetermined scanning angle.

[0125] In one embodiment, beam scanning is performed within a predetermined scanning angle using an effective beam of beam splitting on the resources indicated by the resource configuration information. In one embodiment, the difference between the gain of the effective beam and the gain of the center beam is less than or equal to a gain threshold; and the difference between the gain of the ineffective beam and the gain of the center beam is greater than the gain threshold. In another embodiment, the gain of the effective beam is greater than the gain threshold; and the gain of the ineffective beam is less than the gain threshold.

[0126] In one embodiment, the predetermined scanning angle is determined based on the number of beams resulting from beam splitting. In one embodiment, in response to the number of beams resulting from beam splitting being greater than a threshold number, the predetermined scanning angle is determined to be greater than an angle threshold; in response to the number of beams resulting from beam splitting being less than the threshold number, the predetermined scanning angle is determined to be less than the angle threshold. In this manner, the predetermined scanning angle can be adaptively adjusted based on the number of beams resulting from beam splitting.

[0127] It should be noted that those skilled in the art will understand that the method provided in the embodiments of the present disclosure may be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0128] like Figure 8 As shown, this embodiment provides a beam scanning method, which is applied to a terminal and includes:

[0129] Step 81: In response to the terminal needing to perform beam scanning and the terminal not turning on the beam splitting mode for performing beam splitting, turning on the beam splitting mode.

[0130] In one embodiment, the terminal is in a beam splitting mode for beam splitting, which means that the terminal supports the capability of beam splitting and the beam of the terminal performs beam splitting. The terminal is not in a beam splitting mode for beam splitting, which means that the terminal supports the capability of beam splitting but the beam of the terminal does not perform beam splitting.

[0131] In one embodiment, in response to the terminal needing to perform beam scanning and the terminal being in a beam splitting mode, beam scanning is performed within a predetermined scanning angle using the beam splitting beam on the resources indicated by the resource configuration.

[0132] In another embodiment, in response to the terminal needing to perform beam scanning and the terminal not turning on the beam splitting mode for beam splitting, the beam splitting mode is turned on; on the resources indicated by the resource configuration information, beam scanning is performed within a predetermined scanning angle using the beam splitting beam.

[0133] In one embodiment, the base station instructs the terminal to operate in a split-beam mode or a non-split-beam mode. In one embodiment, in response to the base station allocating resources in the split-beam mode to the terminal, the terminal operates in the split-beam mode. In the split-beam mode, the terminal can perform beam splitting and use the split beams for beam scanning.

[0134] It should be noted that those skilled in the art will understand that the method provided in the embodiments of the present disclosure may be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0135] like Figure 9 As shown, this embodiment provides a beam scanning method, which is applied to a terminal and includes:

[0136] Step 91: In response to the beam scanning of the terminal being completed, turn off the beam splitting mode.

[0137] In one embodiment, in response to obtaining a result of the neighboring cell scanning, it is determined that the beam scanning of the terminal is terminated. Here, the result of the neighboring cell scanning may be the signal quality of the detection signal scanned on the beam of the beam splitting.

[0138] In one embodiment, the beams of beam splitting include multiple effective beams, and the neighboring cell scanning result can be the signal quality of the detection signals scanned on the multiple effective beams. Corresponding detection signals are detected on different effective beams. In one embodiment, the difference between the gain of the effective beam and the gain of the center beam is less than or equal to a gain threshold; the difference between the gain of the ineffective beam and the gain of the center beam is greater than the gain threshold. In another embodiment, the gain of the effective beam is greater than the gain threshold; the gain of the ineffective beam is less than the gain threshold.

[0139] In one embodiment, turning off the beam splitting mode may be that the terminal switches from operating in the beam splitting mode to operating in the non-beam splitting mode. In the non-beam splitting mode, the terminal cannot perform beam splitting.

[0140] It should be noted that those skilled in the art will understand that the method provided in the embodiments of the present disclosure may be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0141] like Figure 10 As shown, this embodiment provides a beam scanning method, which is applied to a terminal and includes:

[0142] Step 101: In response to the completion of beam scanning by the terminal, the signal quality of the detection signal scanned on the beam split by the beam is sent to the base station.

[0143] In one embodiment, in response to the terminal's beam scanning completion, the base station transmits the signal quality of the probe signal scanned on the effective beam of the beam splitting to the base station. In one embodiment, the difference between the gain of the effective beam and the gain of the center beam is less than or equal to a gain threshold; and the difference between the gain of the ineffective beam and the gain of the center beam is greater than the gain threshold. In another embodiment, the gain of the effective beam is greater than the gain threshold; and the gain of the ineffective beam is less than the gain threshold.

[0144] In one embodiment, the signal quality may include at least one of the following: a reference signal received power and a reference signal received quality.

[0145] In one embodiment, the beams of the beam splitting include multiple effective beams, and the channel quality may be the signal quality of the detection signals scanned on the multiple effective beams, wherein corresponding detection signals are scanned on different effective beams.

[0146] In one embodiment, in response to scanning detection signals of the same signal strength and the gain of the first effective beam being greater than the gain of the second effective beam, the signal strength of the wireless signal scanned on the first effective beam is greater than the signal strength of the wireless signal scanned on the second effective beam.

[0147] It should be noted that those skilled in the art will understand that the method provided in the embodiments of the present disclosure may be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0148] like Figure 11 As shown, this embodiment provides a beam scanning method, which is applied to a terminal and includes:

[0149] Step 111: Using a gain difference between the split beam and the central beam, adjust the signal quality of the detection signal scanned on the split beam.

[0150] The center beam is the beam corresponding to the center frequency of the beam splitting.

[0151] Here, see Figure 3 The gain difference in .

[0152] In one embodiment, in response to scanning probe signals of equal signal strength and the gain of the first effective beam being greater than the gain of the second effective beam, the signal strength of the wireless signal scanned on the first effective beam is greater than the signal strength of the wireless signal scanned on the second effective beam. Here, the first effective beam and the second effective beam are beams of beam splitting. The gain difference between the first effective beam and the center beam is different from the gain difference between the second effective beam and the center beam.

[0153] Here, since different scanning results are obtained for detection signals with the same signal strength on different effective beams, it is necessary to perform normalization processing on the signal quality of the detection signals in the scanning results.

[0154] In one embodiment, in response to a gain difference between the split beam and the center beam being greater than a difference threshold, the signal quality of the detection signal may be adjusted to a value greater than the adjustment threshold. For example, in response to a gain difference between the split beam and the center beam being less than a difference threshold, the signal quality of the detection signal may be adjusted to a value less than the adjustment threshold.

[0155] It should be noted that those skilled in the art will understand that the method provided in the embodiments of the present disclosure may be executed alone or together with some methods in the embodiments of the present disclosure or some methods in related technologies.

[0156] like Figure 12 As shown, this embodiment provides a beam scanning method, which is applied to a base station and includes:

[0157] Step 121: Send resource configuration information to the terminal based on the beam splitting capability of the terminal;

[0158] The resource configuration information is used for the terminal to determine resources for beam scanning using beam splitting.

[0159] Here, the terminal can be but is not limited to a mobile phone, a wearable device, a vehicle-mounted terminal, a roadside unit (RSU), a smart home terminal, an industrial sensor device, and other terminals.

[0160] Here, a base station can be an access device for a terminal to access a network. The base station can be of various types. For example, a base station of a third-generation mobile communication (3G) network, a base station of a fourth-generation mobile communication (4G) network, a base station of a fifth-generation mobile communication (5G) network, or a base station of any generation of communication system.

[0161] In one embodiment, the resource configuration information is used for the terminal to determine resources for beam scanning of neighboring cells using beams obtained through beam splitting; wherein the neighboring cells are cells adjacent to the serving cell.

[0162] In one embodiment, while conducting wireless communications in a serving cell, a terminal scans neighboring cells to obtain the radio channel quality of signals on the neighboring cell's beam. After obtaining the radio channel quality measurement results, the terminal transmits the measurement results to the base station. In this way, in response to the radio channel quality of the serving cell falling below a quality threshold, a cell handover can be performed based on the radio channel quality of the neighboring cell.

[0163] In another embodiment scenario, a base station transmits wireless signals using beams in different directions. A terminal measures the quality of the wireless channels transmitted by the base station using beams in different directions using the beams in different directions. After obtaining the measurement results of the wireless channel quality, the terminal reports the measurement information to the base station. The base station determines the transmit beam for data transmission based on the reported information. Here, beam scanning of neighboring cells can be performed by measuring the wireless signals transmitted by the base station using beams.

[0164] In one embodiment, the resource configuration information is used for the terminal to determine resources for performing adjacent beam scanning using a beam splitted by the beam; wherein the adjacent beam is a beam adjacent to the serving beam.

[0165] In one embodiment, a serving base station transmits multiple beams; a beam used for wireless communication between the serving base station and a terminal is a serving beam; and beams adjacent to the serving beam in the multiple beams are adjacent beams of the serving beam. The configured resources indicate resources for performing adjacent beam scanning of the serving beam using beams generated by beam splitting.

[0166] In one embodiment, when a terminal uses a serving beam to communicate wirelessly with a base station, it scans the radio channel quality of adjacent beams. After obtaining a measurement of the radio channel quality, the terminal sends the measurement result to the base station. In this way, if the radio channel quality of the serving beam falls below a quality threshold, a cell handover can be performed based on the radio channel quality of the adjacent beam.

[0167] Here, the wireless channel quality may include at least one of the following: Reference Signal Receiving Power (RSRP) and Reference Signal Receiving Quality (RSRQ).

[0168] In one embodiment, the terminal can perform beam scanning on each of the multiple beams of beam splitting to obtain measurement results on each beam. The base station can configure different resources for different beams. That is, the resource configuration information indicates the resources of the different beams of beam splitting. For example, the beams of beam splitting include beam 1, beam 2, and beam 3, and the configured resources are resource 1, resource 2, and resource 3, respectively. The terminal can perform signal measurement on beam 1, beam 2, and beam 3 on the corresponding resources, respectively, to obtain measurement results on each beam. After the beam scan is completed, the terminal will send the scanning results obtained by scanning on each beam to the base station.

[0169] In one embodiment, a base station receives capability information sent by a terminal; wherein the capability information indicates beam splitting capability supported by the terminal; in response to the base station receiving the capability information and the capability information indicating that the terminal supports beam splitting capability, the base station sends resource configuration information to the terminal according to the capability information; the terminal receives the resource configuration information; the terminal performs beam scanning using the beam splitted beam on the resources indicated by the resource configuration information.

[0170] In one embodiment, a base station receives capability information sent by a terminal, wherein the capability information indicates beam splitting capabilities supported by the terminal. In response to receiving the capability information and the capability information indicating that the terminal does not support beam splitting capabilities, the base station does not send resource configuration information to the terminal. In this case, the terminal can perform beam scanning based on the predetermined resource configuration.

[0171] In one embodiment, in response to the terminal establishing a radio resource control connection with the base station, the terminal sends capability information to the base station, wherein the capability information at least indicates whether the terminal supports or does not support beam splitting.

[0172] In one embodiment, the capability information includes at least one of the following:

[0173] First information, indicating whether the terminal supports or does not support beam splitting capability;

[0174] Second information indicates a spectrum bandwidth of an effective beam of beam splitting; wherein a difference between a gain of the effective beam and a gain of the center beam is less than or equal to a gain threshold; and the center beam is a beam corresponding to a center frequency point of the beam splitting;

[0175] The third information indicates the number of effective beams;

[0176] The fourth information indicates the frequency domain position relationship between the effective beam and the center beam.

[0177] In one embodiment, in response to a terminal's beam being capable of beam splitting, the first information indicates the terminal's support for beam splitting; in response to a terminal's beam being incapable of beam splitting, the first information indicates the terminal's lack of support for beam splitting. Upon receiving the capability information, the base station may allocate resources to the terminal that supports beam splitting. Here, resources may be allocated to each of the multiple beams of the terminal's beam splitting. The terminal may then perform beam scanning using the multiple beams of the beam splitting on the allocated resources.

[0178] In one embodiment, the beams of the beam splitting include multiple beams. The multiple beams include an effective beam and an ineffective beam. In one embodiment, the difference between the gain of the effective beam and the gain of the center beam is less than or equal to a gain threshold; and the difference between the gain of the ineffective beam and the gain of the center beam is greater than the gain threshold. In another embodiment, the gain of the effective beam is greater than the gain threshold; and the gain of the ineffective beam is less than the gain threshold.

[0179] In one embodiment, the beam gain is a parameter associated with the beam's transmit power. In one embodiment, in response to the beam's transmit power being greater than a power threshold, the beam gain is greater than the gain threshold; in response to the beam's transmit power being less than the power threshold, the beam gain is less than the gain threshold.

[0180] In one embodiment, in response to scanning wireless signals of equal signal strength and the gain of the first effective beam being greater than the gain of the second effective beam, the signal strength of the wireless signal scanned on the first effective beam is greater than the signal strength of the wireless signal scanned on the second effective beam. The first effective beam and the second effective beam are beams of beam splitting; and the gain difference between the first effective beam and the center beam is different from the gain difference between the second effective beam and the center beam.

[0181] In one embodiment, in response to the number of effective beams being greater than a quantity threshold, the spectrum bandwidth occupied by the effective beams of the beam splitting is greater than a bandwidth threshold; in response to the number of effective beams being less than a quantity threshold, the spectrum bandwidth occupied by the effective beams of the beam splitting is less than a bandwidth threshold. The base station allocates resources to each effective beam corresponding to this number. Here, the spectrum bandwidth occupied by the effective beam can be the spectrum bandwidth occupied by all effective beams of the beam splitting. In one embodiment, the beam includes a beam corresponding to a center frequency position and a beam corresponding to an edge position. The gain of the beam corresponding to the center frequency position is greater than the gain of the beam corresponding to the edge position.

[0182] In one embodiment, the effective beam of the beam splitting includes multiple beams; wherein the relative frequency domain position relationship between each effective beam and the central beam is different.

[0183] In one embodiment, a base station determines the beam splitting capability of a terminal based on the terminal type; in response to the base station receiving the capability information and the capability information indicating that the terminal supports the beam splitting capability, the base station sends resource configuration information to the terminal based on the beam splitting capability; the terminal receives the resource configuration information; and the terminal performs beam scanning using the beam split on the resources indicated by the resource configuration information. Here, the resource configuration indicates the resources of the multiple beams of the beam splitting.

[0184] In one embodiment, the terminal type includes: a first type that supports beam splitting and a second type that does not support beam splitting. In one embodiment, in response to the terminal type being the first type, it is determined that the terminal supports beam splitting; in response to the terminal type being the second type, it is determined that the terminal does not support beam splitting.

[0185] Here, the resource configuration information may indicate time domain and / or frequency domain resources for beam scanning. In one embodiment, different time domain and / or frequency domain resources are configured for different beams of beam splitting.

[0186] In one embodiment, a base station receives resource configuration information sent based on the beam splitting capability of a terminal. The resource configuration information is used by the terminal to determine resources for beam scanning using an effective beam of beam splitting. Here, the difference between the gain of the effective beam and the gain of the center beam is less than or equal to a gain threshold. The center beam is the beam corresponding to the center frequency of the beam splitting.

[0187] In an embodiment of the present disclosure, resource configuration information is sent to the terminal based on the beam splitting capability of the terminal; the resource configuration information is used for the terminal to determine the resources for beam scanning using the beam splitting beam. In this way, on the one hand, because the base station sends the resource configuration information based on the beam splitting capability of the terminal, the resource configuration can be adapted to the capabilities of the terminal. On the other hand, the terminal can use the beam splitting beam to perform beam scanning on the resources indicated by the resource configuration information. Here, because the terminal can use multiple beams of beam splitting to perform beam scanning, the efficiency of the terminal's beam scanning will be higher compared to the method in which the terminal can only use a single beam to scan neighboring cells.
