DETAILED DESCRIPTION

In the embodiments of the present disclosure, the term "and/or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and/or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the associated objects are in an "or" relationship.

In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

The technical solutions provided by the embodiments of the present disclosure can be applied to a variety of systems, such as 5G systems.

Among them, the terminal involved in the embodiments of the present disclosure may be a device that provides voice and/or data connectivity to a user, a handheld device with wireless connection function, or other processing equipment connected to a wireless modem, etc. In different systems, the name of the terminal may also be different. For example, in a 5G system, the terminal may be called a user equipment (UE). A wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). A wireless terminal device may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device, for example, a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device, which exchanges language and/or data with a radio access network. For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), etc. A wireless terminal device may also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but is not limited to these terms in the embodiments of the present disclosure.

The network device involved in the embodiments of the present disclosure may be a base station, which may include multiple cells providing services to the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The network device can be used to interchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present disclosure may be a network device (Base Transceiver Station, BTS) in the Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolved network device (evolutionary Node B, eNB or e-NodeB) in the Long Term Evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a Home evolved Node B (HeNB), a relay node, a femto base station, a pico base station, etc., but is not limited in the embodiments of the present disclosure. In some network structures, network devices may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and the distributed unit may also be geographically separated.

For example, in the disclosed embodiments, a network device and a terminal device may each use one or more antennas for multiple-input multiple-output (MIMO) transmission. MIMO transmission may be single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Depending on the configuration and number of antenna combinations, MIMO transmission may be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, and may also employ diversity transmission, precoded transmission, or beamforming transmission.

Rel-16 supports measurement and reporting of the L1 Signal to Interference plus Noise Ratio (SINR). Currently, beamforming measurement and reporting of L1-SINR is primarily performed by configuring the corresponding channel measurement resources and interference measurement resources on the terminal through the network device. This triggers the terminal to perform beamforming measurement and reporting of L1-SINR using the configured channel measurement resources and interference measurement resources.

However, the above method cannot promptly reflect the channel changes on the terminal side. If the terminal actively triggers the beam measurement report, the channel changes on the terminal side can be promptly reflected. Therefore, how the terminal actively triggers the beam measurement report is a technical problem that needs to be solved by those skilled in the art.

In order to enable the terminal to actively trigger beam measurement reporting, the embodiment of the present disclosure provides a beam measurement reporting method. Below, the technical solutions in the embodiment of the present disclosure will be clearly and completely described in conjunction with the drawings in the embodiment of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

FIG1 is a flow chart of a beam measurement reporting method provided by an embodiment of the present disclosure, which can be applied to a terminal. For example, referring to FIG1 , the beam measurement reporting method may include:

S101. Perform beam measurement on a reference signal resource to obtain a beam measurement result; wherein the reference signal resource includes a current reference signal resource and/or a candidate reference signal resource.

S102: Determine whether to trigger beam measurement reporting based on the beam measurement result.

It can be seen that in the embodiment of the present disclosure, the terminal obtains a beam measurement result by performing beam measurement on the reference signal resources, where the reference signal resources include the current reference signal resources and/or the candidate reference signal resources. Based on the beam measurement result, it is determined whether to trigger the beam measurement report, thereby enabling the terminal to actively trigger the beam measurement report, so that the channel changes on the terminal side can be reflected in a timely manner when performing beam management.

For example, in an embodiment of the present disclosure, the reference signal resource includes at least one of the following:

Reference signal resources associated with the Transmission Configuration Indication (TCI) state activated by the network device;

Reference signal resources associated with the TCI state indicated by the network device;

Predefined reference signal resources, such as the candidate beam set in Beam Failure Recovery (BFR);

The reference signal resources in the reference signal resource set associated in the Channel State Information (CSI) reporting setting.

For example, in the embodiment of the present disclosure, the reference signal associated with the TCI state may include a type-D reference signal in the TCI state, or may include a reference signal that has a co-site relationship with the type-D reference signal in the TCI state. The specific setting can be made according to actual needs.

For example, in the embodiments of the present disclosure, the beam measurement result may include L1-reference signal receiving power (RSRP), or may also include L1-RSRP and L1-SINR, and of course, may also include hypothetical block error rate (BLER), etc., which can be set according to actual needs.

Typically, when a terminal performs beam measurement on a reference signal resource, it must first determine the reference signal resource. For example, in an embodiment of the present disclosure, the terminal may receive indication information sent by a network device and, based on the indication information, determine the reference signal resource. This allows the terminal to subsequently perform beam measurement on the reference signal resource and obtain a beam measurement result.

For example, in the embodiments of the present disclosure, the indication information can be indication information configured by radio resource control (Radio Resource Control, RRC) signaling, or it can be indication information of downlink control information (Downlink Control Information, DCI), etc., and can be specifically set according to actual needs.

Based on the embodiment shown in FIG. 1 , for example, in the embodiment of the present disclosure, when the terminal determines whether to trigger beam measurement reporting based on the beam measurement result, the determination of whether to trigger beam measurement reporting may include at least the following three possible scenarios based on different reference signal resources:

In a possible scenario, when the reference signal resource includes the current reference signal resource, the terminal may determine whether to trigger beam measurement reporting based on the beam measurement result corresponding to the current reference signal resource.

In this possible scenario, when the terminal determines whether to trigger beam measurement reporting based on the beam measurement result corresponding to the current reference signal resource, it can determine whether the beam measurement result is less than the first threshold. If the beam measurement result is less than the first threshold, the beam measurement reporting is triggered.

The reported information includes: beam measurement results, or beam measurement results and an identifier, and the identifier is used to identify that the reported information is reported information initiated by the terminal.

For example, the reported information may also include trigger event index information and/or CSI-RS resource set index, which can be set according to actual needs.

For example, the current reference signal resource further includes at least one of the following:

Reference signal resources in a reference signal resource set for beam failure recovery (e.g., candidateBeamRSList or failureDetectionResourcesToAddModList);

Reference signal resources associated with the TCI state indicated by the DCI;

Reference signal resources associated with the TCI state activated by the Media Access Control (MAC)-Common Element (CE);

Configure the reference signal resources in the CSI resource setting associated with the CSI reporting of RSRP reported by the UE;

Used to configure the reference signal resources configured in the CSI resource setting associated with the CSI reporting of RSRP reported by the UE;

A reference signal resource set, and the quasi co-location (QCL) source reference signal of the reference signal (RS) in the reference signal resource set is the reference signal resource associated with the TCI state indicated by the DCI, or the reference signal resource associated with the TCI state activated by the MAC-CE.

It can be understood that, in the embodiment of the present disclosure, the value of the first threshold can be set according to actual needs. Here, the embodiment of the present disclosure does not further limit the specific value of the first threshold.

Example 1

In Embodiment 1, the current reference signal resource is a reference signal associated with a TCI state activated by a network device, or a reference signal associated with a TCI state indicated by a network device, and the beam measurement result is L1-RSRP. When a terminal actively triggers a beam measurement report, the following steps may be included:

Step 1. The base station configures a TCI state pool for the terminal and activates n TCI state pools through MAC-CE. In the nth time slot, it indicates the activation of one TCI state for subsequent uplink/downlink channel transmission.

Step 2. The terminal performs channel measurement on the type-D source RS in the activated TCI state, or performs channel measurement on the reference signal that has a co-site relationship with the type-D source RS in the TCI state, to obtain the beam measurement result L1-RSRP of the current reference signal resource.

Step 3: The terminal compares the beam measurement result L1-RSRP with the first threshold T1.

Step 4: When the beam measurement result L1-RSRP<T1, the terminal triggers beam measurement reporting.

For example, in the disclosed embodiments, the terminal-triggered reporting information may include the beam measurement result L1-RSRP, or BQI+CRI1+L1-RSRP. BQI is an identifier used to identify the reporting information as terminal-initiated reporting information, i.e., UE-initiated BM beam measurement reporting.

Step 5: The base station receives the reporting information from the terminal and triggers a new beam management process.

Among them, triggering a new beam management process may be triggering a non-periodic CSS or a semi-persistent CSS to restart a new beam measurement and reporting process.

It can be seen that in this possible implementation method, the terminal performs beam measurement on the current reference signal resource, and triggers the beam measurement report when the beam measurement result of the current reference signal resource is less than the first threshold, thereby realizing the terminal's active triggering of beam measurement reporting, so that the channel changes on the terminal side can be reflected in a timely manner when performing beam management.

In another possible scenario, when the reference signal resources include current reference signal resources and candidate reference signal resources, the terminal may determine whether to trigger beam measurement reporting based on the beam measurement result.

For example, in an embodiment of the present disclosure, when a terminal determines whether to trigger beam measurement reporting based on a beam measurement result, at least two possible implementations may be included:

In a possible implementation, the terminal may trigger beam measurement reporting when a difference between a beam measurement result corresponding to a candidate reference signal resource and a beam measurement result corresponding to a current reference signal resource is greater than a preset threshold.

The reporting information includes: the beam measurement result corresponding to the candidate reference signal resource, or the beam measurement result and identifier corresponding to the candidate reference signal resource, and the identifier is used to indicate that the reporting information is the reporting information initiated by the terminal.

For example, the reported information may also include trigger event index information and/or CSI-RS resource set index, which can be set according to actual needs.

For example, in the embodiment of the present disclosure, the preset threshold may be represented by an offset, and the offset is preconfigured by the base station.

For example, in an embodiment of the present disclosure, after the terminal triggers the beam measurement report, it can also receive a beam switching indication sent by the network device; and based on the beam switching indication, use the candidate reference signal resources to transmit the uplink channel/downlink channel, thereby improving the reliability of the transmission.

For example, in an embodiment of the present disclosure, the beam switching indication may be through a DCI indication, or through a MAC-CE indication, etc., and may be specifically set according to actual needs. Here, the embodiment of the present disclosure does not impose any specific restrictions.

Example 2

In embodiment 2, the current reference signal resource is a predefined reference signal resource, the candidate reference signal resource is a reference signal resource in a reference signal resource set associated in a CSI reporting setting, and when the terminal actively triggers beam measurement reporting, the following steps may be included:

Step 1: The base station configures a predefined reference signal resource set S1 for the terminal, such as a candidate beam set in BFR, for channel measurement.

Step 2. The base station configures a CSI-resource setting for the terminal through the Radio Resource Control (RRC) signaling CSI-ReportConfig. The CSI-resource setting is associated with a CSI-RS resource set1 for interference measurement.

Step 3. The terminal performs channel measurement on the reference signal resources in the reference signal resource set S1 to obtain the beam measurement result S1; and performs interference measurement on the CSI-RS resources in the CSI-RS resource set1 to obtain the beam measurement result P1; and calculates the beam measurement result L1-SINR1 of the current reference signal resource based on the beam measurement results S1 and P1.

Step 4. The terminal performs channel measurement on other reference signal resources in the reference signal resource set S1 to obtain beam measurement results S2, S3, and S4; and performs interference measurement on other CSI-RS resources in the CSI-RS resource set1 to obtain beam measurement results P2, P3, and P4; obtains the beam measurement result L1-SINR2 of the candidate reference signal resource based on the beam measurement results S2 and P2, obtains the beam measurement result L1-SINR3 of the candidate reference signal resource based on the beam measurement results S3 and P3, and obtains the beam measurement result L1-SINR4 of the candidate reference signal resource based on the beam measurement results S4 and P4.

Step 5: The terminal compares the beam measurement results L1-SINR1, L1-SINR2, L1-SINR3, and L1-SINR4. If the beam measurement result L1-SINR4 is greater than the beam measurement result L1-SINR1, and the difference is greater than an offset, the terminal triggers a beam measurement report. The offset value is configured for the terminal by the base station.

For example, in the disclosed embodiments, the terminal-triggered reporting information may include the beam measurement result L1-SINR4, or BQI+CRI4+L1-SINR4. BQI is an identifier used to identify that the reporting information is terminal-initiated reporting information, i.e., UE-initiated BM beam measurement reporting.

Step 7: The base station receives the reporting information from the terminal and sends a beam switching indication to the terminal, so that the terminal uses the candidate reference signal resource CRI4 for uplink channel/downlink channel transmission based on the beam switching indication, thereby improving transmission reliability.

For example, in an embodiment of the present disclosure, the beam switching indication may be through a DCI indication, or through a MAC-CE indication, etc., and may be specifically set according to actual needs. Here, the embodiment of the present disclosure does not impose any specific restrictions.

Example 3

In Example 3, the current reference signal resource is a reference signal resource associated with a TCI state activated or indicated by a network device, and the candidate reference signal resource is a reference signal resource in a reference signal resource set associated in a CSI reporting setting. When the terminal actively triggers beam measurement reporting, the following steps may be included:

Step 1. The base station configures a TCI state pool for the terminal and activates n TCI state pools through MAC-CE. In the nth time slot, it indicates the activation of one TCI state for subsequent uplink/downlink channel transmission.

Step 2: The base station configures a CSI-resource setting for the terminal through RRC signaling CSI-ReportConfig. The CSI-resource setting is associated with a CSI-RS resource set1 for interference measurement. The configuration is as follows:

Step 3. The terminal performs channel measurement on the reference signal resources associated with the TCI state, such as the type-D reference signal in the TCI state or the reference signal that has a co-site relationship with the type-D reference signal in the TCI state, to obtain a beam measurement result S1; and performs interference measurement on the CSI-RS resources in the CSI-RS resource set1 to obtain a beam measurement result P1; and calculates the beam measurement result L1-SINR1 of the current reference signal resource based on the beam measurement results S1 and P1.

Step 4. The terminal performs channel measurement on the reference signal resources associated with the TCI state to obtain beam measurement results S2, S3, and S4; and performs interference measurement on the CSI-RS resources in the CSI-RS resource set1 to obtain beam measurement results P2, P3, and P4; obtains the beam measurement result L1-SINR2 of the candidate reference signal resource based on the beam measurement results S2 and P2, obtains the beam measurement result L1-SINR3 of the candidate reference signal resource based on the beam measurement results S3 and P3, and obtains the beam measurement result L1-SINR4 of the candidate reference signal resource based on the beam measurement results S4 and P4.

Step 5. The terminal compares the beam measurement results L1-SINR1, L1-SINR2, L1-SINR3, and L1-SINR4. If the beam measurement result L1-SINR3 is greater than the beam measurement result L1-SINR1 and the difference is greater than an offset, the terminal triggers the beam measurement report.

For example, in the disclosed embodiments, the terminal-triggered reporting information may include the beam measurement result L1-SINR3, or BQI+CRI3+L1-SINR3. BQI is an identifier used to identify that the reporting information is terminal-initiated reporting information, i.e., UE-initiated BM beam measurement reporting.

Step 7: The base station receives the reporting information from the terminal and sends a beam switching indication to the terminal, so that the terminal uses the candidate reference signal resource CRI3 for uplink channel/downlink channel transmission based on the beam switching indication, thereby improving transmission reliability.

For example, in an embodiment of the present disclosure, the beam switching indication may be through a DCI indication, or through a MAC-CE indication, etc., and may be specifically set according to actual needs. Here, the embodiment of the present disclosure does not impose any specific restrictions.

It can be understood that, in the above embodiment 3, when the terminal reports the beam measurement result L1-RSRP of the candidate reference signal resource, correspondingly, only channel measurement is performed in step 3 and step 4.

Example 4

In embodiment 4, the current reference signal resource and the candidate reference signal resource are both reference signal resources in the reference signal resource set associated in the CSI reporting setting. When the terminal actively triggers beam measurement reporting, the following steps may be included:

Step 1. The base station configures a CSI-resource setting for the terminal through the RRC signaling CSI-ReportConfig. The CSI-resource setting associates two CMRs for channel measurement of the current reference signal resource and the channel measurement of the candidate reference signal resource, and associates two IMRs for channel measurement of the current reference signal resource and interference measurement of the candidate reference signal resource.

For example, the CSI-resource settings associated with CSI-reportConfig are {CMR1, ZP-IMR1} and {CMR2, ZP-IMR2}. CMR1 is used to perform channel measurement on the current reference signal resource, and ZP-IMR1 is used to perform interference measurement on the current reference signal resource. CMR2 is used to perform channel measurement on candidate reference signal resources, and ZP-IMR2 is used to perform interference measurement on candidate reference signal resources. For example, ZP-IMR1/ZP-IMR2 can also be NZP-IMR1/NZP-IMR2, with the following configuration:

The configuration of CMR1/CMR2 can refer to the relevant description in Example 1. The configuration of ZP-IMR1/ZP-IMR2 is as follows:

Step 2. The terminal performs channel measurement on the CSI-RS resources in CMR1 to obtain beam measurement results S1, S2, and S3; and performs interference measurement on the CSI-RS resources in ZP-IMR1 to obtain beam measurement results P1, P2, and P3; obtains the beam measurement result L1-SINR1 of the current reference signal resource based on the beam measurement results S1 and the beam measurement result P1, obtains the beam measurement result L1-SINR2 of the current reference signal resource based on the beam measurement results S2 and the beam measurement result P2, and obtains the beam measurement result L1-SINR3 of the current reference signal resource based on the beam measurement results S3 and the beam measurement result P3.

Step 3. The terminal performs channel measurement on the CSI-RS resources in CMR2 to obtain beam measurement results S4, S5, and S6; and performs interference measurement on the CSI-RS resources in ZP-IMR2 to obtain beam measurement results P4, P5, and P6; obtains the beam measurement result L1-SINR4 of the candidate reference signal resource based on the beam measurement results S4 and P4, obtains the beam measurement result L1-SINR5 of the candidate reference signal resource based on the beam measurement results S5 and P5, and obtains the beam measurement result L1-SINR6 of the candidate reference signal resource based on the beam measurement results S6 and P6.

Step 4. The terminal compares the beam measurement results {SINR1, SINR2, SINR3} of the current reference signal resource with the beam measurement results {SINR4, SINR5, SINR6} of the candidate reference signal resource. If the beam measurement result L1-SINR5 is the largest and the difference is greater than an offset relative to the beam measurement result L1-SINR3, the terminal triggers the beam measurement report.

For example, in the disclosed embodiments, the terminal-triggered reporting information may include the beam measurement result CRI5+L1-SINR5, or BQI+CRI5+L1-SINR5. BQI is an identifier used to identify that the reporting information is terminal-initiated reporting information, i.e., UE-initiated BM beam measurement reporting.

Step 5: The base station receives the reporting information from the terminal and sends a beam switching indication to the terminal, so that the terminal uses the beam CRI5 corresponding to the candidate reference signal resource to transmit uplink/downlink channels based on the beam switching indication, thereby improving the reliability of transmission.

For example, in an embodiment of the present disclosure, the beam switching indication may be through a DCI indication, or through a MAC-CE indication, etc., and may be specifically set according to actual needs. Here, the embodiment of the present disclosure does not impose any specific restrictions.

It can be seen that in this possible implementation method, the terminal performs beam measurement on the current reference signal resource, and triggers the beam measurement report when the beam measurement result corresponding to the candidate reference signal resource is greater than the beam measurement result corresponding to the current reference signal resource, thereby realizing the terminal's active triggering of beam measurement reporting, so that the channel changes on the terminal side can be reflected in a timely manner when performing beam management.

In another possible implementation, the terminal may trigger beam measurement reporting when the beam measurement result corresponding to the current reference signal resource is less than a first threshold and the beam measurement result corresponding to the candidate reference signal resource is greater than a second threshold, where the second threshold is greater than the first threshold.

The reporting information includes: the beam measurement result corresponding to the candidate reference signal resource, or the beam measurement result and identifier corresponding to the candidate reference signal resource, and the identifier is used to indicate that the reporting information is the reporting information initiated by the terminal.

For example, the reported information may also include trigger event index information and/or CSI-RS resource set index, which can be set according to actual needs.

For example, in an embodiment of the present disclosure, after the terminal triggers the beam measurement report, it can also receive a beam switching indication sent by the network device; and based on the beam switching indication, use the candidate reference signal resources to transmit the uplink channel/downlink channel.

Example 5

In embodiment 5, the current reference signal resource is a reference signal resource in a reference signal resource set associated in the CSI reporting setting, and the candidate reference signal resource is a reference signal resource in another reference signal resource set associated in the CSI reporting setting. When the terminal actively triggers beam measurement reporting, the following steps may be included:

Step 1. The base station configures CMR1 and IMR1 for the terminal through RRC signaling CSI-ReportConfig. CMR1 is associated with two CSI-RS resource sets, CSI-RS resource set1 and CSI-RS resource set2, and IMR1 is associated with two CSI-IMs, CSI-IM1 and CSI-IM2.

Step 2. The terminal performs channel measurement on the reference signal resources in CSI-RS resource set1 to obtain beam measurement results S1 and S3; and performs interference measurement on the reference signal resources in CSI-IM1 to obtain beam measurement results P1 and P3; obtains the beam measurement result L1-SINR1 of the current reference signal resource based on the beam measurement results S1 and P1, and obtains the beam measurement result L1-SINR3 of the current reference signal resource based on the beam measurement results S3 and P3.

Step 3. The terminal performs channel measurement on the reference signal resources in CSI-RS resource set2 to obtain beam measurement results S2 and S4; and performs interference measurement on the reference signal resources in CSI-IM2 to obtain beam measurement results P2 and P4; obtains the beam measurement result L1-SINR2 of the candidate reference signal resource based on the beam measurement results S2 and P2, and obtains the beam measurement result L1-SINR4 of the candidate reference signal resource based on the beam measurement results S4 and P4.

Step 4: The terminal compares the beam measurement result {SINR1, SINR3} of the current reference signal resource with the beam measurement result {SINR2, SINR4} of the candidate reference signal resource. If the beam measurement result L1-SINR2 is the largest, the terminal triggers the beam measurement report.

For example, in the disclosed embodiments, the terminal-triggered reporting information may include the beam measurement result CRI2+L1-SINR2, or BQI+CRI2+L1-SINR2. BQI is an identifier used to identify that the reporting information is terminal-initiated reporting information, i.e., beam measurement reporting of UE-initiated BM.

Step 5: The base station receives the reporting information from the terminal and sends a beam switching indication to the terminal, so that the terminal uses the beam CRI2 corresponding to the candidate reference signal resource to transmit uplink/downlink channels based on the beam switching indication, thereby improving the reliability of transmission.

For example, in an embodiment of the present disclosure, the beam switching indication may be through a DCI indication, or through a MAC-CE indication, etc., and may be specifically set according to actual needs. Here, the embodiment of the present disclosure does not impose any specific restrictions.

It can be seen that in this possible implementation method, the terminal performs beam measurement on the current reference signal resource, and triggers beam measurement reporting when the beam measurement result corresponding to the current reference signal resource is less than the first threshold and the beam measurement result corresponding to the candidate reference signal resource is greater than the second threshold, so that the channel changes on the terminal side can be reflected in a timely manner when performing beam management.

In another possible scenario, when the reference signal resources include candidate reference signal resources, the terminal may determine whether to trigger beam measurement reporting based on the beam measurement result.

In this possible scenario, when the terminal determines whether to trigger beam measurement reporting based on the beam measurement result corresponding to the candidate reference signal resource, it can determine whether the beam measurement result is greater than a second threshold. If the beam measurement result is greater than the second threshold, the beam measurement reporting is triggered.

The reported information includes: beam measurement results, or beam measurement results and an identifier, and the identifier is used to indicate that the reported information is reported information initiated by the terminal.

It can be understood that, in the embodiment of the present disclosure, the value of the second threshold can be set according to actual needs. Here, the embodiment of the present disclosure does not further limit the specific value of the second threshold.

For example, in an embodiment of the present disclosure, after the terminal triggers the beam measurement report, it can also receive a beam switching indication sent by the network device; and based on the beam switching indication, use the candidate reference signal resources to transmit the uplink channel/downlink channel.

For example, in an embodiment of the present disclosure, the beam switching indication may be through a DCI indication, or through a MAC-CE indication, etc., and may be specifically set according to actual needs. Here, the embodiment of the present disclosure does not impose any specific restrictions.

Example 6

In embodiment 6, the candidate reference signal resource is a predefined reference signal resource, such as a reference signal resource in a candidate beam set in BFR, and the beam measurement result is L1-RSRP. When the terminal actively triggers beam measurement reporting, the following steps may be included:

Step 1: The base station configures a predefined reference signal resource set S1 for the terminal, where the reference signal resource can be a periodic CSI-RS or SSB, and the reference signal resource set S1 can also be a candidate beam set in BFR.

Step 2: The terminal performs channel measurement on the reference signal resources in the reference signal resource set S1 to obtain the beam measurement result L1-RSRP of the candidate reference signal resources.

Step 3: The terminal compares the beam measurement result L1-RSRP with the second threshold T2.

Step 4: When the beam measurement result L1-RSRP>T2, the terminal triggers beam measurement reporting.

For example, in the disclosed embodiments, the terminal-triggered reporting information may include the beam measurement result L1-RSRP, or BQI+CRI2+L1-RSRP. BQI is an identifier used to identify the reporting information as terminal-initiated reporting information, i.e., UE-initiated BM beam measurement reporting.

Step 5: The base station receives the reporting information from the terminal and sends a beam switching indication to the terminal, so that the terminal uses the beam CRI2 corresponding to the candidate reference signal resource to transmit uplink/downlink channels based on the beam switching indication, thereby improving the reliability of transmission.

Example 7

In embodiment 7, the candidate reference signal resource is a reference signal resource in a reference signal resource set associated in a CSI reporting setting, the beam measurement result is L1-RSRP, and when the terminal actively triggers beam measurement reporting, the following steps may be included:

Step 1. The base station configures a CSI-resource setting for the terminal through RRC signaling CSI-ReportConfig. The CSI-resource setting is associated with a CSI-RS resource set1.

Step 2. The terminal performs channel measurement on the CSI-RS resources in CSI-RS resource set1 to obtain beam measurement results L1-RSRP1, L1-RSRP2, L1-RSRP3, and L1-RSRP4 of the candidate reference signal resources.

Step 3: The terminal compares the beam measurement results L1-RSRP1, L1-RSRP2, L1-RSRP3 and L1-RSRP4 with the second threshold T2.

Step 4: When the beam measurement results L1-RSRP1>T2 and L1-RSRP3>T2, the terminal triggers beam measurement reporting.

For example, in the disclosed embodiments, the terminal-triggered reporting information may include beam measurement results CRI1+L1-RSRP1 and CRI3+L1-RSRP3, or BQI+CRI1+L1-RSRP1 and BQI+CRI3+L1-RSRP3. BQI is an identifier used to identify that the reporting information is terminal-initiated, i.e., beam measurement reporting for UE-initiated BM.

Step 5: The base station receives the reporting information from the terminal and sends a beam switching indication to the terminal, so that the terminal uses the beam CRI1 corresponding to the candidate reference signal resource to transmit uplink/downlink channels based on the beam switching indication, thereby improving transmission reliability.

For example, in an embodiment of the present disclosure, the beam switching indication may be through a DCI indication, or through a MAC-CE indication, etc., and may be specifically set according to actual needs. Here, the embodiment of the present disclosure does not impose any specific restrictions.

It can be seen that in this possible implementation method, the terminal performs beam measurement on the current reference signal resource, and triggers beam measurement reporting when the beam measurement result is greater than the second threshold, so that the channel changes on the terminal side can be reflected in a timely manner when performing beam management.
