Abstract

This disclosure provides an information reporting and beam switching method, apparatus, and storage medium. The information reporting method includes: determining an optimal receiving beam corresponding to at least one transmit beam; and reporting the optimal receiving beam corresponding to the at least one transmit beam to a base station. In this disclosure, a terminal can determine the optimal receiving beam corresponding to at least one transmit beam and report it to the base station. Based on the terminal's report, the base station can determine whether beam switching is required within the same channel occupancy time. If the transmitted beam after switching is consistent with the optimal receiving beam corresponding to the transmitted beam before switching, the base station can directly perform beam switching without needing to detect channel occupancy each time beam switching occurs, reducing the time overhead of beam switching within the same channel occupancy time and improving availability.

Description

Technical Field

[0001] This disclosure relates to the field of communications, and in particular to information reporting, beam switching methods and apparatus, and storage media. Background Technology

[0002] In the unlicensed spectrum from 52.6 GHz to 71 GHz, base stations and terminals need to determine whether the channel is occupied before communicating. Only if it is determined that the channel is not occupied can a COT (Channel Occupancy Time) be initiated and communication be carried out in the COT.

[0003] However, in a COT, if it is necessary to switch the transmit beam, the channel occupancy status of the new transmit beam is unknown. Therefore, each time a new transmit beam is switched, the channel occupancy status of the new transmit beam needs to be confirmed, which increases the time overhead of beam switching.

When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0128] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure.

It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of at least one associated listed item.

[0129] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0130] The following section will first introduce the information reporting method provided in this publication from the perspective of the terminal side.

[0131] This disclosure provides an information reporting method, referring to... Figure 1 As shown, Figure 1 This is a flowchart illustrating an information reporting method according to an embodiment, which can be used in a terminal. The method may include the following steps:

[0132] In step 101, the optimal receiving beam corresponding to at least one transmitting beam is determined.

[0133] In this embodiment of the disclosure, the terminal can determine the optimal receiving beam corresponding to at least one transmitting beam through beam measurement. The transmitting beam refers to the beam used by the base station to transmit reference signals, data, and / or signaling, while the receiving beam refers to the beam used by the terminal to receive the aforementioned information transmitted by the base station. Specifically, during beam measurement, after the base station fixes a transmitting beam, the terminal uses beam scanning to determine the optimal receiving beam corresponding to the current transmitting beam from among its multiple receiving beams. The optimal receiving beam may be the receiving beam with the best quality of the received reference signal among the multiple receiving beams.

[0134] In step 102, the optimal receive beam corresponding to at least one of the transmit beams is reported to the base station.

[0135] In the above embodiments, after the terminal determines the optimal receiving beam corresponding to at least one of the transmitting beams, it can report it to the base station so that the base station can perform beam switching based on the report from the terminal, which is simple and highly available.

[0136] In some alternative embodiments, the terminal may report the optimal receive beam corresponding to at least one transmit beam to the base station based on an instruction from the base station side.

[0137] Reference Figure 2 As shown, Figure 2 This is a flowchart illustrating an information reporting method according to an embodiment, which can be used in a terminal. The method may include the following steps:

[0138] In step 201, the reporting instruction information sent by the base station is received.

[0139] In one possible implementation, the reporting indication information is used to indicate whether to report the optimal receiving beam corresponding to at least one of the transmitted beams.

[0140] In one possible implementation, the reporting indication information is used to indicate the number of targets of the transmitted beam reported each time. The number of targets can be one or more, and this disclosure does not limit this.

[0141] In another possible implementation, the reporting indication information is used to indicate whether to report the optimal receiving beam corresponding to at least one of the transmitted beams, and the target number of the transmitted beams reported each time.

[0142] In step 202, the optimal receiving beam corresponding to at least one transmitting beam is determined.

[0143] In step 203, based on the reporting indication information, the optimal receiving beam corresponding to at least one of the transmitting beams is reported to the base station.

[0144] In the above embodiments, the terminal can report the best receiving beam corresponding to at least one transmitting beam to the base station based on the reporting indication information sent by the base station, which has high availability.

[0145] In some alternative embodiments, refer to Figure 3 As shown, Figure 3 This is a flowchart illustrating an information reporting process according to an embodiment, which can be used in a terminal. The method may include the following steps:

[0146] In step 301, the reporting instruction information sent by the base station is received.

[0147] In this embodiment of the disclosure, the reporting indication information is used at least to indicate whether to report the optimal receiving beam corresponding to at least one of the transmitted beams.

[0148] In step 302, the optimal receiving beam corresponding to at least one transmitting beam is determined.

[0149] In step 303, in response to determining that the reporting indication information indicates reporting the optimal receiving beam corresponding to at least one of the transmitting beams, the optimal receiving beam corresponding to at least one of the transmitting beams is reported to the base station.

[0150] In the above embodiments, the terminal can report the above content to the base station when the base station instructs the terminal to report the best receiving beam corresponding to at least one transmitting beam, which is simple to implement and highly available.

[0151] In some alternative embodiments, refer to Figure 4 As shown, Figure 4 This is a flowchart illustrating an information reporting method according to an embodiment, which can be used in a terminal. The method may include the following steps:

[0152] In step 401, the reporting instruction information sent by the base station is received.

[0153] In this embodiment of the disclosure, the base station can use a separate identifier in an RRC (Radio Resource Control) signaling to indicate whether the terminal reports the optimal receive beam corresponding to at least one of the transmit beams.

[0154] In step 402, the optimal receiving beam corresponding to at least one transmitting beam is determined.

[0155] In step 403, in response to determining that the first identifier included in the first information element in the received first RRC signaling is a first preset value, the reporting indication information is determined to indicate that the optimal receiving beam corresponding to at least one of the transmitted beams is reported.

[0156] In this embodiment of the disclosure, the first information unit may be an information unit for configuring CSI (Channel State Information) reporting, i.e., a CSI-ReportConfig information unit. The base station adds a first identifier to the first information unit in the first RRC signaling. This first identifier is an identifier used to indicate whether to report the optimal receive beam corresponding to at least one of the transmit beams.

[0157] When the terminal determines that the first identifier is a first preset value, it determines that the reporting instruction information indicates that the optimal receiving beam corresponding to at least one of the transmitted beams should be reported. The first preset value can be 1 or 0, and this disclosure does not limit it.

[0158] In step 404, in response to determining that the reporting indication information indicates reporting the optimal receiving beam corresponding to at least one of the transmit beams, the optimal receiving beam corresponding to at least one of the transmit beams is reported to the base station.

[0159] In the above embodiments, the terminal can determine, based on the first identifier in the first RRC signaling sent by the base station, that the base station instructs the terminal to report the optimal receiving beam corresponding to at least one of the transmitted beams, and then report the optimal receiving beam corresponding to at least one of the transmitted beams to the base station, thereby avoiding the waste of resources caused by the terminal automatically reporting when the base station does not allow it.

[0160] In some alternative embodiments, refer to Figure 5 As shown, Figure 5 This is a flowchart illustrating an information reporting method according to an embodiment, which can be used in a terminal. The method may include the following steps:

[0161] In step 501, the reporting instruction information sent by the base station is received.

[0162] In this embodiment of the disclosure, the base station may reuse an existing identifier in an RRC signaling to indicate whether the terminal reports the best receive beam corresponding to at least one of the transmit beams.

[0163] In step 502, the optimal receiving beam corresponding to at least one transmitting beam is determined.

[0164] In step 503, in response to determining that the first parameter included in the second information element in the received second RRC signaling is configured to be on, and the second parameter included in the first information element associated with the second information element is not configured to be empty, the reporting indication information is determined to indicate reporting the optimal receiving beam corresponding to at least one of the transmit beams.

[0165] In this embodiment, the second information unit may be an information unit for configuring a non-zero power CSI reference signal resource set, such as the NZP-CSI-RS-ResourceSet information unit. The first parameter included in the second information unit may be the REPETITIN parameter. The first information unit may be an information unit for configuring CSI reporting, i.e., the CSI-ReportConfig information unit, where the second parameter may be, but is not limited to, the reportQuanity parameter. When the measurement reference signal set configured by the first information unit includes the reference signal configured by the second information unit, the first information unit is determined to be associated with the second information unit.

[0166] In related technologies, if the first parameter is configured to be ON, then the second parameter in the associated first information unit must be configured to none. In this embodiment, if the terminal determines that the first parameter included in the second information unit is configured to ON and the second parameter included in the associated first information unit is not configured to none, then it determines that the reporting indication information indicates reporting the optimal receiving beam corresponding to at least one of the transmitted beams. Optionally, the second parameter can be configured as L1 (Layer 1, physical layer)-RSRP (Reference Signal Receiving Power), L1-SINR (Signal to Interference plus Noise Ratio), or other values, which are not limited in this disclosure.

[0167] In step 504, in response to determining that the reporting indication information indicates reporting the optimal receiving beam corresponding to at least one of the transmit beams, the optimal receiving beam corresponding to at least one of the transmit beams is reported to the base station.

[0168] In the above embodiments, the terminal can determine, based on the identifier reused in the second RRC signaling sent by the base station, that the base station instructs the terminal to report the optimal receiving beam corresponding to at least one of the transmitted beams, and then report the optimal receiving beam corresponding to at least one of the transmitted beams to the base station, thereby avoiding the waste of resources caused by the terminal automatically reporting when the base station does not allow it.

[0169] In some alternative embodiments, refer to Figure 6 As shown, Figure 6 This is a flowchart illustrating an information reporting method according to an embodiment, which can be used in a terminal. The method may include the following steps:

[0170] In step 601, the reporting instruction information sent by the base station is received.

[0171] In this embodiment of the disclosure, the base station can indicate the number of reported targets using a third parameter in the RRC signaling. The third parameter can be a parameter used to indicate the number of targets, including but not limited to a parameter newly added to the RRC signaling. Alternatively, the third parameter can be a specified parameter reused for the number of targets; optionally, the specified parameter can be the nroReportedRS parameter. In step 602, the optimal receive beam corresponding to at least one transmit beam is determined.

[0172] In step 603, in response to determining that the number of targets indicated by the reporting indication information is one, after determining the optimal receiving beam corresponding to each transmitting beam, the optimal receiving beam corresponding to the transmitting beam is reported to the base station.

[0173] In this embodiment of the disclosure, the third RRC signaling may be the same RRC signaling as the first RRC signaling or a different RRC signaling, or the third RRC signaling may be the same RRC signaling as the second RRC signaling or a different RRC signaling; this disclosure does not limit this. The terminal determines the number of targets to be one based on the third parameters included in the received third RRC signaling. Then, after determining the optimal receiving beam corresponding to each transmit beam, the terminal reports the optimal receiving beam corresponding to that transmit beam to the base station.

[0174] In the above embodiments, during beam measurement, the terminal can use the reporting indication information sent by the base station to perform beam scanning on the terminal side each time. After determining the best receiving beam corresponding to a transmitting beam, it reports to the base station, which is simple to implement and has high availability.

[0175] In some alternative embodiments, refer to Figure 7 As shown, Figure 7This is a flowchart illustrating an information reporting method according to an embodiment, which can be used in a terminal. The method may include the following steps:

[0176] In step 701, the reporting instruction information sent by the base station is received.

[0177] In this embodiment of the disclosure, the base station can indicate the target number to be reported using a third parameter in the RRC signaling. The third parameter can be a parameter used to indicate the target number, including but not limited to a parameter newly added to the RRC signaling. Alternatively, the third parameter can be a specified parameter reused for the target number; optionally, the specified parameter can be the `nroReportedRS` parameter.

[0178] In step 702, the optimal receiving beam corresponding to at least one transmitting beam is determined.

[0179] In step 703, in response to determining that the number of targets indicated by the reporting indication information is multiple, after determining the optimal receiving beams corresponding to the transmit beams of the target number, the optimal receiving beams corresponding to the transmit beams of the target number are reported to the base station.

[0180] In this embodiment of the disclosure, the third RRC signaling may be the same as or different from the first RRC signaling, or the third RRC signaling may be the same as or different from the second RRC signaling; this disclosure does not limit this. The terminal determines that there are multiple targets based on the third parameters included in the received third RRC signaling. Only after determining the optimal receiving beam corresponding to each transmit beam of the target number will the terminal report the optimal receiving beam corresponding to that transmit beam to the base station.

[0181] Optionally, the number of targets can be four. When there are four targets, after the terminal determines the optimal receiving beam corresponding to each of the four transmit beams, it reports the optimal receiving beam corresponding to each of the four transmit beams to the base station after the fourth and final terminal-side beam scan.

[0182] In the above embodiments, after determining the optimal receiving beams corresponding to the target number of transmit beams during beam measurement, the terminal can report the optimal receiving beams corresponding to the target number of transmit beams to the base station, which is simple to implement and highly available.

[0183] In some alternative embodiments, in response to determining that the reporting indication information indicates reporting the optimal receiving beam corresponding to at least one of the transmitted beams, the terminal determines to report the optimal receiving beam corresponding to at least one transmitted beam to the base station. Specifically, the terminal may, based on a predetermined number of transmitted beams pre-agreed by the protocol, report the optimal receiving beam corresponding to the predetermined number of transmitted beams to the base station after determining the optimal receiving beam corresponding to the predetermined number of transmitted beams.

[0184] In another possible implementation, the terminal determines the target number of the transmit beams to be reported each time based on the reporting instruction information. After determining the target number, the terminal determines that the base station allows the reporting of the best receive beam corresponding to at least one transmit beam. Then, after determining the best receive beams corresponding to the target number of transmit beams, the terminal reports the best receive beams corresponding to the target number of transmit beams to the base station.

[0185] In another possible implementation, the reporting indication information simultaneously indicates whether to report the optimal receiving beam corresponding to at least one of the transmitted beams, and the target number of the transmitted beams to be reported each time. The terminal needs to report to the base station only if the reporting indication information indicates that the optimal receiving beam corresponding to at least one of the transmitted beams should be reported, and if the optimal receiving beams corresponding to the target number of transmitted beams have been determined.

[0186] The above is merely an illustrative example. In practical applications, other schemes that report the best receiving beam corresponding to the transmitting beam based on the base station indication should also fall within the protection scope of this disclosure.

[0187] In the above embodiments, the terminal can report the optimal receiving beam corresponding to at least one of the transmitted beams to the base station based on the base station's indication, so that the base station can perform beam switching based on the terminal's report, which is simple and highly available.

[0188] In some alternative embodiments, the terminal may report the optimal receive beam corresponding to at least one transmit beam to the base station in the following manner:

[0189] The terminal assigns a number to its own receiving beams and determines the index value corresponding to each receiving beam. After completing beam scanning, the terminal, based on the reporting instruction information sent by the base station, reports the optimal receiving beam corresponding to at least one transmitting beam to the base station through PUCCH (Physical Uplink Control Channel) resources and / or PUSCH (Physical Uplink Shared Channel) resources.

[0190] Specifically, the terminal reports to the base station the identification information of at least one of the transmitted beams and the index value of the optimal received beam corresponding to the at least one transmitted beam. The identification information of the transmitted beam includes at least one of the following: the CRI (CSI-RS Resource Indicator) corresponding to the transmitted beam; and / or the SSBI (SSB Resource Indicator) corresponding to the transmitted beam.

[0191] In the above embodiments, the terminal can report the identification information of at least one of the transmit beams and the index value of the optimal receive beam corresponding to at least one of the transmit beams to the base station through PUCCH resources and / or PUSCH resources, so that the base station can perform beam switching based on the content reported by the terminal side, which is simple and highly available.

[0192] In the above embodiments, the embodiments involving the identification information of the transmit beam and / or the index value of the receive beam can be applied to any other embodiment outside of this application, and this disclosure does not limit them. Any scheme involving determining the transmit beam identifier and / or the receive beam index value should fall within the protection scope of this disclosure.

[0193] In some alternative embodiments, the terminal can actively initiate a scheduling request to request the base station to allocate target resources for the terminal to report the optimal receiving beam corresponding to at least one of the transmitted beams, and then report the optimal receiving beam corresponding to at least one of the transmitted beams to the base station through the target resources.

[0194] In the above embodiments, the embodiment in which the terminal actively initiates the scheduling request can be applied to any embodiment of this application, and of course, it can also be applied to any other embodiment besides this application. This disclosure does not limit it in this regard.

[0195] Reference Figure 8 As shown, Figure 8 This is a flowchart illustrating an information reporting method according to an embodiment, which can be used in a terminal. The method may include the following steps:

[0196] In step 801, the optimal receiving beam corresponding to at least one transmitting beam is determined.

[0197] In step 802, a first scheduling request is sent to the base station.

[0198] In this embodiment of the disclosure, after completing beam measurement and determining the optimal receiving beam corresponding to at least one transmit beam, the terminal can send the first scheduling request to the base station, wherein the first scheduling request is used to request the base station to configure target resources for the terminal for reporting the optimal receiving beam corresponding to at least one transmit beam.

[0199] In step 803, resource indication information sent by the base station to indicate the target resource is received.

[0200] In step 804, based on the resource indication information, the optimal receive beam corresponding to at least one of the transmit beams is reported to the base station through the target resource.

[0201] In the above embodiments, after completing beam measurement and determining the optimal receiving beam corresponding to at least one transmit beam, the terminal can obtain target resources through a first scheduling request, and then report the optimal receiving beam corresponding to at least one transmit beam to the base station based on the target resources. This also achieves the purpose of reporting the optimal receiving beam corresponding to at least one transmit beam to the base station, resulting in high availability.

[0202] In some alternative embodiments, refer to Figure 9 As shown, Figure 9 This is a flowchart illustrating an information reporting method according to an embodiment, which can be used in a terminal. The method may include the following steps:

[0203] In step 901, the optimal receiving beam corresponding to at least one transmitting beam is determined.

[0204] In step 902, the first scheduling request is sent to the base station on the first resource configured by the base station for the terminal.

[0205] In this embodiment of the disclosure, the first resource is used only for the terminal to send the first scheduling request. That is, the first resource is a resource configured by the base station for the terminal specifically for sending the first scheduling request.

[0206] In step 903, resource indication information sent by the base station to indicate the target resource is received.

[0207] In step 904, based on the resource indication information, the optimal receive beam corresponding to at least one of the transmit beams is reported to the base station via the first PUSCH Media Access Control Information Unit (MAC CE) on the target resource.

[0208] In this embodiment of the disclosure, the terminal can report the optimal receive beam corresponding to at least one of the transmit beams to the base station via a first PUSCH MAC CE (MAC Control Element, Media Access Control Unit). Specifically, the first PUSCH MAC CE includes at least: identification information of at least one of the transmit beams and an index value of the optimal receive beam corresponding to at least one of the transmit beams. The identification information of the transmit beam includes at least one of the following: a CSI reference signal resource indicator corresponding to the transmit beam; and / or a synchronization signal block resource indicator corresponding to the transmit beam.

[0209] In the above embodiments, the terminal can send a first scheduling request through the dedicated first resource configured by the base station for the terminal. Furthermore, the terminal can report the best receiving beam corresponding to at least one transmit beam to the base station based on the target resource configured by the base station, thereby achieving the purpose of reporting the receiving beam corresponding to at least one transmit beam to the base station, which has high availability.

[0210] In some alternative embodiments, refer to Figure 10 As shown, Figure 10 This is a flowchart illustrating an information reporting method according to an embodiment, which can be used in a terminal. The method may include the following steps:

[0211] In step 1001, the optimal receiving beam corresponding to at least one transmitting beam is determined.

[0212] In step 1002, based on the multiplexing indication information sent by the base station, a second resource for sending the first scheduling request is determined.

[0213] The multiplexing indication information is used to instruct the second resource to reuse a specified resource pre-allocated to the terminal, wherein the specified resource is the resource in which the terminal sends the second scheduling request. In this embodiment of the disclosure, the second scheduling request may be a BFR (Beam Failure Recovery) scheduling request for a SCell (Secondary Cell) or other scheduling requests, and this disclosure does not limit it.

[0214] In step 1003, the first scheduling request is sent to the base station on the second resource.

[0215] In step 1004, resource indication information sent by the base station to indicate the target resource is received.

[0216] In step 1005, based on the resource indication information, the optimal receive beam corresponding to at least one of the transmit beams is reported to the base station via a second PUSCH MACCE on the target resource, and the second PUSCH MACCE carries at least a second identifier.

[0217] In this embodiment of the disclosure, when the terminal reports via the second PUSCH MAC CE, the second PUSCH MAC CE must include at least a second identifier to indicate that the information reported via the second PUSCH MAC CE is the optimal receiving beam corresponding to at least one of the transmit beams. Additionally, the second PUSCH MAC CE may also include: identification information of at least one of the transmit beams and an index value of the optimal receiving beam corresponding to at least one of the transmit beams. The identification information of the transmit beam includes at least one of the following: a CSI reference signal resource indicator corresponding to the transmit beam; and / or a synchronization signal block resource indicator corresponding to the transmit beam.

[0218] In one possible implementation, the second identifier, if set to 1, can identify the reported information content as the optimal receiving beam corresponding to at least one of the transmitted beams, and if set to 0, can identify the reported information content as information content related to BFR.

[0219] In another possible implementation, the second identifier, if set to 0, can identify the reported information content as the optimal receiving beam corresponding to at least one of the transmitted beams, and if set to 1, can identify the reported information content as information content related to BFR.

[0220] In the above embodiments, the terminal can reuse the second resource to send a first scheduling request to the base station. Furthermore, when the terminal reports the optimal receive beam corresponding to at least one of the transmit beams based on the target resources configured by the base station, it needs to carry at least a second identifier in the second PUSCH MAC CE, thereby indicating that the reported information content is the optimal receive beam corresponding to at least one of the transmit beams. This achieves the purpose of reporting the receive beam corresponding to at least one transmit beam to the base station, resulting in high availability.

[0221] The beam switching method provided in this disclosure will now be introduced from the perspective of the base station.

[0222] Reference Figure 11 As shown, Figure 11 This is a flowchart illustrating a beam switching method according to an embodiment, which can be used in a base station. The method may include the following steps:

[0223] In step 1101, the receiving terminal reports the optimal receiving beam corresponding to at least one transmitting beam.

[0224] In step 1102, in response to determining that the signal is switched from the first transmit beam to the second transmit beam during the same channel occupancy time, a first optimal receive beam corresponding to the first transmit beam and a second optimal receive beam corresponding to the second transmit beam are determined based on the optimal receive beam reported by the terminal corresponding to at least one of the transmit beams.

[0225] In this embodiment of the disclosure, if the base station determines that beam switching will be performed within the same COT, it can determine the first optimal receiving beam corresponding to the first transmitting beam and the second optimal receiving beam corresponding to the second transmitting beam based on the optimal receiving beam reported by the terminal that corresponds to at least one of the transmitting beams.

[0226] In step 1103, in response to determining that the first optimal receiving beam and the second optimal receiving beam are the same beam, the signal is switched from the first transmitting beam to the second transmitting beam.

[0227] In this embodiment of the disclosure, if the base station determines that the first optimal receiving beam and the second optimal receiving beam are the same beam, then the base station does not need to perform LBT (Listen before Talk) and can directly perform beam switching.

[0228] In the above embodiments, if the base station determines to perform beam switching based on the terminal's report and the optimal receiving beam corresponding to the transmit beam after switching is consistent with the transmit beam before switching, the base station can directly perform beam switching without having to detect channel occupancy every time a transmit beam switch is performed. This reduces the time overhead of beam switching within the same channel occupancy time and improves availability.

[0229] In some alternative embodiments, refer to Figure 12 As shown, Figure 12 This is a flowchart illustrating a beam switching method according to an embodiment, which can be used in a base station. The method may include the following steps:

[0230] In step 1201, the receiving terminal reports the optimal receiving beam corresponding to at least one transmitting beam.

[0231] In step 1202, in response to determining that the signal is switched from the first transmit beam to the second transmit beam during the same channel occupancy time, a first optimal receive beam corresponding to the first transmit beam and a second optimal receive beam corresponding to the second transmit beam are determined based on the optimal receive beam reported by the terminal corresponding to at least one of the transmit beams.

[0232] In step 1203, in response to determining that the first optimal receiving beam and the second optimal receiving beam are different beams, when the LBT result indicates that the channel is not occupied, the transmission beam is switched from the first transmitting beam to the second transmitting beam.

[0233] In the above embodiments, the base station can determine whether to perform beam switching based on the LBT result when the optimal receiving beam corresponding to the transmit beam before and after the switch is different, based on the terminal side report. This achieves the purpose of beam switching in the same way, and is simple to implement and highly available.

[0234] In some alternative embodiments, refer to Figure 13 As shown, Figure 13 This is a flowchart illustrating a beam switching method according to an embodiment, which can be used in a base station. The method may include the following steps:

[0235] In step 1301, a reporting instruction message is sent to the terminal.

[0236] The reporting indication information is used to indicate at least one of the following: whether to report first indication information of the optimal receiving beam corresponding to at least one of the transmitted beams; and / or the target number of the transmitted beams reported each time.

[0237] In step 1302, the receiving terminal reports the optimal receiving beam corresponding to at least one transmitting beam.

[0238] Optionally, if the reporting indication information indicates that the first indication information corresponding to the optimal receiving beam corresponding to at least one of the transmitted beams is to be reported, the base station can receive the optimal receiving beam corresponding to at least one of the transmitted beams reported by the terminal.

[0239] Alternatively, if the reporting indication information indicates the target number of the transmitted beams reported each time, the base station can receive the optimal received beam corresponding to the target number of transmitted beams reported by the terminal.

[0240] Alternatively, if the reporting indication information indicates the reporting of a first indication information for the optimal receiving beam corresponding to at least one of the transmitted beams, and indicates the target number of the transmitted beams reported each time, the base station can receive the optimal receiving beam corresponding to the target number of transmitted beams reported by the terminal.

[0241] If the reporting indication information indicates that no reporting is allowed, then the base station will not receive the optimal receiving beam reported by the terminal that corresponds to at least one of the transmitted beams.

[0242] That is, step 1301 can be implemented alone, or step 1301 can be implemented together with step 1302. Alternatively, step 1301 and step 1302 can be implemented in combination with step 1102 and step 1103, or step 1301 and step 1302 can be implemented in combination with step 1202 and step 1203. This disclosure does not limit this.

[0243] In the above embodiments, the base station can instruct the terminal to report or not report the optimal receiving beam corresponding to at least one of the transmitted beams by reporting indication information, or it can instruct the terminal to report the optimal receiving beams corresponding to a target number of transmitted beams by reporting indication information. Further optionally, the base station can perform beam switching based on the terminal's report, which is simple and has high availability.

[0244] In some alternative embodiments, refer to Figure 14 As shown, Figure 14 This is a flowchart illustrating a beam switching method according to an embodiment, which can be used in a base station. The method may include the following steps:

[0245] In step 1401, a first RRC signaling including a first information element is sent to the terminal, wherein the first information element includes a first identifier.

[0246] The first information unit is used to configure Channel State Information (CSI) reporting, and the first identifier is used to indicate whether to report the optimal receive beam corresponding to at least one of the transmit beams. The base station can use the first identifier included in the first information unit in the first RRC signaling to indicate whether the terminal should report first indication information for the optimal receive beam corresponding to at least one of the transmit beams.

[0247] In one possible implementation, when the first identifier is a first preset value, it is used to instruct the terminal to report the optimal receiving beam corresponding to at least one of the transmitted beams, wherein the first preset value can be 1 or 0, and this disclosure does not limit it.

[0248] In another possible implementation, when the first identifier is a second preset value, it is used to instruct the terminal not to report the optimal receive beam corresponding to at least one of the transmit beams. The second preset value differs from the first preset value; when the first preset value is 1, the second preset value can be 0, and vice versa.

[0249] In step 1402, the receiving terminal reports the optimal receiving beam corresponding to at least one transmitting beam.

[0250] Step 1401 can be implemented alone, or step 1401 can be implemented together with step 1402. Alternatively, steps 1401 and 1402 can be implemented in combination with steps 1102 and 1103, or steps 1401 and 1402 can be implemented in combination with steps 1202 and 1203. This disclosure does not limit the implementation of these steps.

[0251] In the above embodiments, the base station can instruct the terminal to report or not report the optimal receive beam corresponding to at least one of the transmit beams through the first identifier included in the first RRC signaling. Further optionally, the base station can perform beam switching based on the terminal's report, which is simple and has high availability.

[0252] In some alternative embodiments, refer to Figure 15 As shown, Figure 15 This is a flowchart illustrating a beam switching method according to an embodiment, which can be used in a base station. The method may include the following steps:

[0253] In step 1501, a second RRC signaling, including a second information unit and a first information unit associated with the second information unit, is sent to the terminal.

[0254] The second information unit can be an information unit for configuring a non-zero power CSI reference signal resource set, such as the NZP-CSI-RS-ResourceSet information unit. The first information unit can be an information unit for configuring CSI reporting, i.e., the CSI-ReportConfig information unit. The first information unit associated with the second information unit means that if the CSI reference signal configured by the second information unit is, for example, the resource set of CSI-RS #n, then the associated first information unit is also used to configure the reporting of CSI-RS #n. The first and second information units together indicate whether to report the optimal receive beam corresponding to at least one of the transmitted beams.

[0255] In one possible implementation, when the first parameter included in the second information unit is configured to be enabled and the second parameter included in the first information unit is not configured to be empty, it is used to instruct the terminal to report the optimal receive beam corresponding to at least one of the transmit beams. The first parameter included in the second information unit may be a REPETITIN parameter, and the second parameter may be a reportQuanity parameter.

[0256] In another possible implementation, when the first parameter included in the second information unit is configured to be enabled, and the second parameter included in the first information unit is configured to be empty, it is used to instruct the terminal not to report the optimal receive beam corresponding to at least one of the transmit beams. The first parameter included in the second information unit may be a REPETITIN parameter, and the second parameter may be a reportQuanity parameter.

[0257] In step 1502, the receiving terminal reports the optimal receiving beam corresponding to at least one transmitting beam.

[0258] Step 1501 can be performed alone, or step 1501 can be performed together with step 1502. The specific decision on whether to perform step 1501 and step 1502 together depends on the content of the reported instruction information. Alternatively, steps 1501 and 1502 can be combined with steps 1102 and 1103, or steps 1501 and 1502 can be combined with steps 1202 and 1203. This disclosure does not limit the specific implementation of these steps.

[0259] In the above embodiments, the base station can reuse the existing identifiers included in the second RRC signaling to instruct the terminal to report or not report the optimal receiving beam corresponding to at least one of the transmit beams. Further optionally, the base station can perform beam switching based on the terminal's report, which is simple and has high availability.

[0260] In some alternative embodiments, refer to Figure 16 As shown, Figure 16 This is a flowchart illustrating a beam switching method according to an embodiment, which can be used in a base station. The method may include the following steps:

[0261] In step 1601, a third RRC signaling including a third parameter is sent to the terminal.

[0262] In this embodiment of the disclosure, the third parameter is a parameter used to indicate the target number, or the third parameter is a specified parameter reused by the target number. Optionally, the specified parameter may be an nroReportedRS parameter. The third RRC signaling and the first RRC signaling may be the same RRC signaling or different RRC signaling, or the third RRC signaling and the aforementioned second RRC signaling may be the same RRC signaling or different RRC signaling.

[0263] In step 1602, the receiving terminal reports the optimal receiving beam corresponding to the target number of transmit beams.

[0264] Step 1602 above is also optional. The terminal may report to the base station after receiving the third RRC signaling and determining the optimal receive beam corresponding to the target number of transmit beams. The terminal may also need to determine whether reporting is allowed based on the reporting indication information sent by the base station before sending the optimal receive beam corresponding to the target number of transmit beams to the base station.

[0265] Optionally, steps 1601 and 1602 may be implemented in combination with steps 1102 to 1103, or steps 1601 and 1602 may be implemented in combination with steps 1202 to 1203. This disclosure does not limit the implementation of these steps.

[0266] In the above embodiments, the base station can instruct the terminal to determine the optimal receiving beam corresponding to the target number of transmit beams through the third parameter included in the third RRC signaling, which is simple to implement and has high availability.

[0267] In some alternative embodiments, refer to Figure 17 As shown, Figure 17 This is a flowchart illustrating a beam switching method according to an embodiment, which can be used in a base station. The method may include the following steps:

[0268] In step 1701, a first scheduling request sent by the terminal is received.

[0269] In this embodiment of the disclosure, the first scheduling request is used to request the base station to configure target resources for the terminal for reporting the optimal receive beam corresponding to at least one of the transmit beams.

[0270] In step 1702, target resources are configured for the terminal.

[0271] In step 1703, resource indication information for indicating the target resource is sent to the terminal.

[0272] In the embodiments of this disclosure, steps 1701 to 1703 can be implemented together, without being implemented in conjunction with other steps provided in this disclosure. Alternatively, they can be combined with steps 1101 to 1103, meaning that after step 1703 is completed, step 1101 is executed until step 1103 is completed. Or, steps 1701 to 1703 can also be combined with steps 1201 to 1203, and this disclosure does not limit this.

[0273] In the above embodiments, the base station can configure target resources for the terminal to transmit the optimal receive beam corresponding to at least one transmit beam based on the first scheduling request sent by the terminal, so that the terminal can report the optimal receive beam corresponding to at least one transmit beam. Furthermore, the base station can perform beam switching based on the terminal's report, resulting in high availability.

[0274] In some alternative embodiments, refer to Figure 18 As shown, Figure 18 This is a flowchart illustrating a beam switching method according to an embodiment, which can be used in a base station. The method may include the following steps:

[0275] In step 1801, a first resource is configured for the terminal, and the first resource is used only for the terminal to send the first scheduling request.

[0276] In step 1802, a first scheduling request sent by the terminal through the first resource is received.

[0277] In step 1803, the target resources are configured for the terminal.

[0278] In step 1804, resource indication information for indicating the target resource is sent to the terminal.

[0279] In step 1805, the first PUSCH MAC CE reported by the terminal through the target resource is received.

[0280] Specifically, the first PUSCH MAC CE includes at least: identification information of at least one of the transmit beams and an index value of the optimal receive beam corresponding to at least one of the transmit beams. The identification information of the transmit beam includes at least one of the following: a CSI reference signal resource indicator corresponding to the transmit beam; and / or a synchronization signal block resource indicator corresponding to the transmit beam.

[0281] Optionally, after receiving the first PUSCH MAC CE, when performing beam switching, the base station can determine whether the optimal receive beam corresponding to the transmit beam before and after the switch is the same beam. If it is the same beam, beam switching can be performed directly. If they are different beams, the base station can determine whether to perform beam switching based on the LBT result.

[0282] In the above embodiments, the base station can configure a first resource for the terminal to transmit the optimal receive beam corresponding to at least one of the transmit beams, so that the terminal can send a first scheduling request. The base station configures the target resource for the terminal based on the first scheduling request. Furthermore, the base station can perform beam switching based on reports from the terminal side, eliminating the need to detect channel occupancy every time a transmit beam switch is performed, reducing the time overhead of beam switching within the same channel occupancy time, and improving availability.

[0283] In some alternative embodiments, refer to Figure 19 As shown, Figure 19 This is a flowchart illustrating a beam switching method according to an embodiment, which can be used in a base station. The method may include the following steps:

[0284] In step 1901, multiplexing instruction information is sent to the terminal.

[0285] The reuse indication information is used to instruct the second resource to reuse a specified resource pre-allocated to the terminal. The second resource is the resource in which the terminal sends the first scheduling request, and the specified resource is the resource in which the terminal sends the second scheduling request.

[0286] Optionally, the second scheduling request may be a BFR scheduling request of SCell, or other scheduling requests, which are not limited in this disclosure.

[0287] In step 1902, a first scheduling request sent by the terminal through the second resource is received.

[0288] In step 1903, the target resources are configured for the terminal.

[0289] In step 1904, resource indication information for indicating the target resource is sent to the terminal.

[0290] In step 1905, a second PUSCH MAC CE reported by the terminal through the target resource is received, wherein the second PUSCH MAC CE carries at least a second identifier.

[0291] The second identifier can be used to indicate that the information content is the optimal receiving beam corresponding to at least one transmit beam. Optionally, the second PUSCH MAC CE further includes: identification information of at least one of the transmit beams and an index value of the optimal receiving beam corresponding to at least one of the transmit beams. The identification information of the transmit beam includes at least one of the following: a CSI reference signal resource indicator corresponding to the transmit beam; and / or a synchronization signal block resource indicator corresponding to the transmit beam.

[0292] Optionally, after receiving the second PUSCH MAC CE, the base station determines the information content carried by it according to the second identifier. Thus, when performing beam switching, it can determine whether the optimal receiving beam corresponding to the transmit beam before and after the switch is the same beam. If it is the same beam, beam switching can be performed directly. If it is a different beam, the base station can determine whether to perform beam switching based on the LBT result.

[0293] In the above embodiments, the base station can instruct the terminal to reuse the second resource for sending the second scheduling request, so that the terminal can send the first scheduling request. The base station configures the target resource for the terminal based on the first scheduling request. Furthermore, the base station can perform beam switching based on reports from the terminal side, eliminating the need to detect channel occupancy every time a transmit beam switch is performed, reducing the time overhead of beam switching within the same channel occupancy time, and improving availability.

[0294] In some optional embodiments, the base station receives identification information of at least one of the transmit beams reported by the terminal, as well as the index value of the optimal receive beam corresponding to the at least one transmit beam. The identification information of the transmit beam includes at least one of the following: a CSI reference signal resource indicator corresponding to the transmit beam; and / or a synchronization signal block resource indicator corresponding to the transmit beam.

[0295] In some alternative embodiments, refer to Figure 20 As shown, Figure 20 This is a flowchart illustrating a beam switching method according to an embodiment, which may include the following steps:

[0296] In step 2001, the base station sends a reporting instruction to the terminal.

[0297] The reporting indication information is used to indicate at least one of the following: whether to report the optimal receiving beam corresponding to at least one of the transmitting beams; and / or the target number of the transmitting beams reported each time.

[0298] In step 2002, the optimal receiving beam corresponding to at least one transmitting beam is determined.

[0299] In step 2003, the terminal reports the optimal receiving beam corresponding to at least one transmitting beam to the base station based on the reporting indication information.

[0300] In step 2004, in response to determining that the base station switches from the first transmit beam to the second transmit beam during the same channel occupancy time, the base station determines a first optimal receive beam corresponding to the first transmit beam and a second optimal receive beam corresponding to the second transmit beam based on the optimal receive beam reported by the terminal corresponding to at least one of the transmit beams.

[0301] In step 2005, in response to determining that the first optimal receiving beam and the second optimal receiving beam are the same beam, the base station switches from the first transmitting beam to the second transmitting beam.

[0302] Alternatively, step 2005 can be replaced with step 2005' ( Figure 20 (not shown in the image) In response to determining that the first optimal receive beam and the second optimal receive beam are different beams, when the LBT result indicates that the channel is not occupied, the signal is switched from the first transmit beam to the second transmit beam.

[0303] Reference Figure 21 As shown, before entering the channel occupancy time, the base station can first perform LBT, and if the LBT result indicates that the channel is not occupied, the channel occupancy time can be entered.

[0304] Alternatively, the terminal can also perform receiver-assisted LBT, which allows the channel to be occupied for a specified time if the LBT results from the base station and the terminal indicate that the channel is not occupied.

[0305] After the channel occupancy period begins, the base station needs to switch from transmit beam #1 to transmit beam #2. The base station determines that the optimal receive beam for both transmit beam #1 and beam #2 is receive beam #2. Therefore, the base station does not need to perform LBT (Low-Time Bypass) and can directly switch from transmit beam #1 to transmit beam #2. If the base station needs to switch from transmit beam #1 to transmit beam #3, and the base station determines that the optimal receive beams for transmit beam #1 and beam #3 are receive beam #2 and receive beam #3 respectively, the base station needs to determine, based on the LBT results, that the channel is not occupied before switching from transmit beam #1 to transmit beam #3.

[0306] In the above embodiments, the terminal can determine the optimal receiving beam corresponding to at least one transmit beam and report the optimal receiving beam corresponding to at least one transmit beam to the base station. Based on the report from the terminal, the base station can determine whether to perform beam switching within the same channel occupancy time. If the transmit beam after switching is consistent with the optimal receiving beam corresponding to the transmit beam before switching, the base station can directly perform beam switching without needing to detect channel occupancy every time a transmit beam switch is performed, thus reducing the time overhead of beam switching within the same channel occupancy time and improving availability.

[0307] In some alternative embodiments, refer to Figure 22 As shown, Figure 22This is a flowchart illustrating a beam switching method according to an embodiment, which can be used in a base station. The method may include the following steps:

[0308] In step 2201, the terminal determines the optimal receiving beam corresponding to at least one transmitting beam.

[0309] In step 2202, the terminal sends a first scheduling request to the base station.

[0310] The first scheduling request is used to request the base station to configure target resources for the terminal to report the optimal receive beam corresponding to at least one of the transmit beams.

[0311] In step 2203, the base station determines the target resource for the terminal.

[0312] In step 2204, the base station sends resource indication information to the terminal to indicate the target resource.

[0313] In step 2205, the terminal reports the optimal receive beam corresponding to at least one transmit beam to the base station through the target resource.

[0314] In step 2206, in response to determining that the base station switches from the first transmit beam to the second transmit beam during the same channel occupancy time, the base station determines a first optimal receive beam corresponding to the first transmit beam and a second optimal receive beam corresponding to the second transmit beam based on the optimal receive beam reported by the terminal corresponding to at least one of the transmit beams.

[0315] In step 2207, in response to determining that the first optimal receiving beam and the second optimal receiving beam are the same beam, the base station switches from the first transmitting beam to the second transmitting beam.

[0316] Alternatively, step 2207 can be replaced with step 2207' ( Figure 22 (not shown in the image) In response to determining that the first optimal receive beam and the second optimal receive beam are different beams, when the LBT result indicates that the channel is not occupied, the signal is switched from the first transmit beam to the second transmit beam.

[0317] Similarly, its beam switching process is the same as Figure 21 The process shown is similar and will not be repeated here.

[0318] In the above embodiments, the terminal can determine the optimal receiving beam corresponding to at least one transmit beam and report the optimal receiving beam corresponding to at least one transmit beam to the base station. Based on the report from the terminal, the base station can determine whether to perform beam switching within the same channel occupancy time. If the transmit beam after switching is consistent with the optimal receiving beam corresponding to the transmit beam before switching, the base station can directly perform beam switching without needing to detect channel occupancy every time a transmit beam switch is performed, thus reducing the time overhead of beam switching within the same channel occupancy time and improving availability.
