Description

Technical Field

[0001] The present application relates to the field of wireless access networks, and in particular to a communication method, apparatus, related equipment and storage medium. Background Art

[0002] In traditional beam management, the network can configure / activate frequent periodic or semi-persistent beam reporting, or trigger frequent aperiodic beam reporting, to timely acquire the best / preferred beam for data / control transmission. However, this obviously results in large reporting and control signaling overhead. Furthermore, if less frequent beam reporting is configured, the network cannot always acquire the "best / preferred" beam because the beam report from the user equipment (UE) may be outdated, resulting in performance degradation.

[0003] Given that the UE has better and more timely understanding of changes in beam quality, a UE-initiated beam reporting procedure allows the network to obtain more timely beam reports while reducing reporting overhead. In this process, if the UE determines, for example, that the current beam quality has deteriorated, it can trigger a beam report. Therefore, it is necessary to consider how to implement the terminal-triggered beam reporting procedure. Summary of the Invention

[0110] The present application will be described in further detail below with reference to the accompanying drawings and embodiments.

[0111] For long BSR, LCG_i=0, which means that the buffer size field of LCG_i does not exist. The Buffer Size field is in ascending order according to the LCG_i sequence, and the logical channel group corresponding to LCGi=1 reports the buffer size respectively. Figure 1 As shown, Figure 1 Diagram showing the reporting of buffer size for a logical channel group.

[0112] In the traditional beam management process, the network can configure / activate frequent periodic or semi-persistent beam reports (for example, N best beams and corresponding L1 RSRPs), or trigger frequent non-periodic beam reports to timely obtain the best / preferred beam for data / control transmission. However, this obviously leads to large UL reporting overhead and control signaling overhead. At the same time, if less frequent beam reporting is configured, the network cannot always obtain the "best / preferred" beam because the UE's beam report may be outdated, resulting in performance degradation. Considering that the UE has better and more timely understanding of beam quality changes, the UE-initiated beam reporting process allows the network to obtain more timely beam reports while reducing reporting overhead. Under such a process, if the UE determines that, for example, the current beam quality has deteriorated, the UE can trigger beam reporting, and the network does not need to configure or trigger frequent reporting.

[0113] Based on this, in various embodiments of the present application, the terminal determines that a preset condition is met, and the terminal sends first information indicating the measurement result of the terminal to the network device, thereby implementing a beam reporting process triggered by the terminal.

[0114] The embodiment of the present application provides a communication method, which is applied to a terminal, such as Figure 2 As shown, Figure 2 This is a flow chart of a communication method according to an embodiment of the present application, including:

[0115] Step 201: When the terminal determines that a preset condition is met, the terminal sends first information to a network device, where the first information is used to indicate a measurement result of the terminal.

[0116] It should be noted that the preset condition can be determined according to the specific situation and is not limited here. As an example, the preset condition may include at least one of the following: the RSRP or SINR of the RS or SSB of the QCL configured in the TCI state is less than the first preset threshold; the RSRP or SINR of the preconfigured first RS is greater than the second preset threshold; the RSRP or SINR of the preconfigured first SSB is greater than the second preset threshold; the RSRP or SINR of at least one of the preconfigured first RS or the preconfigured first SSB is greater than the RSRP or SINR of the QCL configured in the TCI state by a third preset threshold; the quality of the first beam is less than the fourth preset threshold; the quality of at least one second beam is greater than the quality of the first beam by a fifth preset threshold; the quality of the second beam is greater than the sixth preset threshold. In practical applications, the preset condition may be referred to as the first condition. When the terminal determines that the preset condition is satisfied, it may be when the terminal determines that the first condition is satisfied.

[0117] The first information can be determined based on specific circumstances and is not limited herein. As an example, the first information can include at least one of the following: CRI; SSBID; TCI state ID; RSRP; SINR; event identifier; and no alternative RS. In practical applications, sending the first information to the network device can include sending a CRI, SSBID, TCI state ID, RSRP, SINR, or event identifier to the network device.

[0118] The first information is used to indicate a measurement result of the terminal. The measurement result may be determined according to specific circumstances and is not limited here. As an example, the measurement result may be a measurement result of the current beam.

[0119] In this embodiment of the present application, upon a terminal determining that a preset condition is satisfied, the terminal transmits first information indicating the terminal's measurement result to a network device. Specifically, the terminal can trigger a beam reporting process. For example, if the current beam quality deteriorates, the UE has a better and more timely understanding of the beam quality change. The UE-initiated beam reporting process allows the network to obtain more timely beam reports, while reducing reporting overhead and enabling a terminal-triggered beam reporting process.

[0120] In one embodiment, the preset condition includes at least one of the following:

[0121] The RSRP or SINR of the QCL or SSB configured in the TCI state is less than the first preset threshold;

[0122] The RSRP or SINR of the preconfigured first RS is greater than a second preset threshold;

[0123] The RSRP or SINR of the preconfigured first SSB is greater than a second preset threshold;

[0124] The RSRP or SINR of at least one of the preconfigured first RS or the preconfigured first SSB is greater than the RSRP or SINR of the QCL configured in the TCIstate or SSB and is greater than a third preset threshold;

[0125] The quality of the first beam is less than a fourth preset threshold;

[0126] The quality of at least one second beam is greater than the quality of the first beam by a fifth preset threshold;

[0127] The quality of the second beam is greater than a sixth preset threshold.

[0128] In this embodiment, the first preset threshold, the second preset threshold, the third preset threshold, the fourth preset threshold, the fifth preset threshold, and the sixth preset threshold can all be determined based on specific circumstances and are not limited here. The first preset threshold, the second preset threshold, the third preset threshold, the fourth preset threshold, the fifth preset threshold, and the sixth preset threshold can all be the same or different. In actual applications, the first preset threshold, the second preset threshold, the third preset threshold, the fourth preset threshold, the fifth preset threshold, and the sixth preset threshold can all be referred to as thresholds.

[0129] The first beam and the second beam may be determined according to specific circumstances and are not limited here. As an example, the first beam may be the current beam; the second beam may be a new beam, and the new beam may be L1-RSRP.

[0130] In practical applications, if the quality of the first beam is less than the fourth preset threshold, it can be understood that the quality of the current beam is worse than the threshold. If the quality of at least one second beam is greater than the quality of the first beam by a fifth preset threshold, it can be understood that the quality of at least one new beam (e.g., L1-RSRP) is better than the quality of the current beam by a threshold. If the quality of the second beam is greater than the sixth preset threshold, it can be understood that the quality of the new beam is better than the threshold.

[0131] As an example, the preset condition can be referred to as the first condition, and the first condition may include Event-1: Quality of the current beam is worse than a certain threshold (i.e., Event-1: the quality of the current beam is worse than a threshold). Event-2: Quality of at least one new beam, such as L1-RSRP, becomes a threshold value better than the current beam (i.e., Event-2: the quality of at least one new beam (such as L1-RSRP) is better than the quality of the current beam than the threshold). Event-3: Quality of a new beam is better than a certain threshold (i.e., Event-3: the quality of a new beam is better than a certain threshold). Event-4: Quality of the current beam is worse than a threshold 1, and quality of atleast one new beam is better than a threshold 2 (i.e., Event-4: the quality of the current beam is worse than a threshold, and the quality of at least one new beam is better than the threshold).

[0132] In one embodiment, the first information includes at least one of the following:

[0133] CRI;

[0134] SSBID;

[0135] TCI state ID;

[0136] RSRP;

[0137] SINR;

[0138] Event identifier;

[0139] No alternative RS.

[0140] In this embodiment, the RSRP may be determined according to specific circumstances and is not limited herein. As an example, the RSRP may include L1-RSRP, filtered RSRP, L3-RSRP, and the like.

[0141] The SINR may be determined according to specific circumstances and is not limited here. As an example, the SINR may include L1-SINR, filtered SINR, L3-SINR, and the like.

[0142] In actual applications, the terminal sending the first information to the network device may be the terminal sending CRI, SSBID, TCI state ID, RSRP, SINR, event identifier, no alternative RS, etc. to the network device. As an example, the terminal sends a new CRI / SSBID or TCI state ID to the network to indicate that the network expects the beam to be switched to the reported CRI / SSBID or TCI state to be updated to the TCI state ID.

[0143] In one embodiment, the method further comprises:

[0144] The first information is reported in the MAC CE of the BSR.

[0145] In this embodiment, the specific process of reporting the first information in the MAC CE of the BSR can be determined according to the specific situation and is not limited here. As an example, reporting the first information in the MAC CE of the BSR may include reporting the first information in the MAC CE when the value of at least one LCG in the BSR is zero.

[0146] In actual application, the first information may include CRI or SSBID or TCI state ID; reporting the first information in the MACCE of the BSR may be reporting CRI / SSBID or TCI state ID in the MAC CE of the Regular / periodic long BSR (Buffer Status Report).

[0147] In one embodiment, reporting the first information in the MAC CE of the BSR includes:

[0148] When a value of at least one logical channel group LCG in the BSR is zero, the first information is reported in the MAC CE.

[0149] In this embodiment, when the value of at least one logical channel group LCG in the BSR is zero, the specific reporting in the first information reported in the MAC CE is determined according to the specific situation, which is not limited here. As an example, when the value of at least one logical channel group LCG in the BSR is zero, reporting the first information in the MAC CE can be when the value of at least one logical channel group LCG in the BSR is zero, after the value of the LCG is a corresponding cache data buffer size field, using the remaining bit field in the MAC CE to report the CRI, the SSBID or the TCI state ID.

[0150] In actual applications, when at least one LCG_i=0, after the buffer size field corresponding to LCG_i=1 ends, the remaining bit field is used to report the CRI / SSBID or TCI state ID.

[0151] In one embodiment, the method includes:

[0152] determining the number of zero values ​​of the LCG;

[0153] When the number of LCG values ​​​​that are zero is greater than or equal to the seventh preset threshold, it is determined that the number of reported CRI or the SSBID or the TCI state ID or the SINR or the RSRP or the event identifier is less than or equal to the seventh preset threshold; the seventh preset threshold is configured by the network device.

[0154] In this embodiment, the seventh preset threshold can be determined according to actual conditions and is not limited here. As an example, the seventh preset threshold can be recorded as X.

[0155] In actual applications, when there are greater than or equal to X LCG_i = 0, a maximum of X CRI / SSBIDs or TCI state IDs can be reported, or the first parameter indicates no candidate RS. The value of X can be configured by the network side. However, when the BSR bit resources are insufficient, the number of CRI / SSBIDs or TCI state IDs reported is determined based on the remaining BSR bits.

[0156] In one embodiment, the method further comprises:

[0157] The first information is reported on a first PUSCH or a first PUCCH.

[0158] In this embodiment, reporting the first information on the first PUSCH can be understood as directly reporting the first information on the PUSCH when there are PUSCH resources.

[0159] Reporting the first information on the first PUCCH can be understood as reporting the first information on the PUCCH when there is PUCCH scheduling.

[0160] In one embodiment, the method further comprises:

[0161] Sending a first RACH or a first SR to the network device to request a second PUSCH or a second PUCCH, and reporting the first information on the second PUSCH or the second PUCCH; or,

[0162] A second RACH or a second SR is sent to the network device to instruct the terminal to report the first information on a third PUSCH or a third PUCCH.

[0163] In this embodiment, the first RACH and the first SR can be determined based on actual conditions and are not limited here. As an example, the first RACH can be a dedicated RACH resource; the first SR can be a dedicated SR request. The sending of the first RACH or the first SR to the network device to request a second PUSCH or a second PUCCH, and reporting the first information on the second PUSCH or the second PUCCH can be understood as the terminal sending a dedicated RACH resource or a dedicated SR to the network device to request a second PUSCH or a second PUCCH, and reporting the first information on the second PUSCH or the second PUCCH.

[0164] The second RACH and the second SR can be determined based on actual conditions and are not limited here. As an example, the second RACH can be a dedicated RACH resource; the second SR can be a dedicated SR request. The sending of the second RACH or the second SR to the network device to instruct the terminal to report the first information on the third PUSCH or the third PUCCH can be understood as the terminal sending a dedicated RACH resource or a dedicated SR request to the network device to instruct the terminal to report the first information on the third PUSCH or the third PUCCH.

[0165] In actual applications, when there are PUSCH resources, the terminal directly reports the first information on the PUSCH; when there is no PUSCH scheduling, the terminal first sends a dedicated RACH resource or a dedicated SR to request a PUSCH resource, and then reports the first information on the PUSCH.

[0166] In one embodiment, the method further comprises:

[0167] Configuring a first resource set; wherein the first resource set includes a CSI-RS or an SSB;

[0168] Report the first parameter and the second parameter;

[0169] When the value of the first parameter is 1, the second parameter is used to indicate a CRI or SSBID or TCI state ID or SINR or RSRP or event identifier, where the CRI or SSBID corresponds to the CSI-RS and SSB in the first resource set;

[0170] When the first parameter takes a value of 0, the second parameter is used to indicate that there is no alternative reference signal or the second parameter bit field is reserved.

[0171] In this embodiment, the first resource set includes a CSI-RS or SSB; configuring the first resource set may include configuring a CSI-RS or SSB resource set. The CSI-RS or SSB may be used to determine a beam management measurement resource set triggered by the terminal. In actual applications, RRC separately configures a CSI-RS / SSB resource set for UE-triggered beam management measurement, adding a new MAC CE.

[0172] Reporting a first parameter and a second parameter; wherein the first parameter and the second parameter can be determined according to actual conditions and are not limited here. As an example, the value of the first parameter can include 0 or 1. The second parameter can be an indication parameter.

[0173] The correspondence between the CRI or SSBID and the CSI-RS and SSB in the first resource set can be understood as the existence of a correspondence between the CRI or SSBID and the CSI-RS and SSB in the first resource set.

[0174] In actual applications, RRC separately configures the CSI-RS / SSB resource set for UE-triggered beam management measurement, adding a new MAC CE; when the first parameter = 1, the CRI / SSBID field indicates that the CRI / SSBID represents the RS selected by the terminal from the CSI-RS / SSB resource set, and reports the L1-RSRP / L1-SINR of the indicated RS (optional). When the first parameter = 0, it indicates no candidate RS.

[0175] In one embodiment, the method further comprises:

[0176] Reporting an association between the first information and a channel state information reporting identifier, a channel state information resource configuration, or a channel state information resource set;

[0177] Report the first parameter and the second parameter;

[0178] When the value of the first parameter is 1, the second parameter is used to indicate CRI or SSBID or TCI state ID or SINR or RSRP or event identifier;

[0179] When the first parameter takes a value of 0, the second parameter is used to indicate that there is no alternative reference signal or the second parameter bit field is reserved.

[0180] In this embodiment, the channel state information reporting identifier, channel state information resource configuration, or channel state information resource set can be determined based on actual conditions and is not limited here.

[0195] Reporting the TCI state ID; the TCI state ID is used to represent the target TCI state ID that the terminal expects to apply; or,

[0196] The no alternative reference information is reported; the no alternative reference information is used to indicate that no alternative reference signal meets the preset condition.

[0197] In this embodiment, the first information includes a TCI state ID; the TCI state ID is used to represent the target TCI state ID that the terminal expects to apply; reporting the TCI state ID can be understood as the terminal sending a new TCI state ID to the network, and the new TCI state ID is used to indicate that the network expects the beam to switch to the reported TCIstate and update to the TCI state ID.

[0198] The first information includes no alternative reference information; the no alternative reference information is used to characterize that no alternative reference signal meets the preset condition; wherein, the preset condition can be determined according to the specific situation and is not limited here. As an example, the preset condition may include at least one of the following: the RSRP or SINR of the RS or SSB of the QCL configured in the TCI state is less than the first preset threshold; the RSRP or SINR of the preconfigured first RS is greater than the second preset threshold; the RSRP or SINR of the preconfigured first SSB is greater than the second preset threshold; the RSRP or SINR of at least one of the preconfigured first RS or the preconfigured first SSB is greater than the RSRP or SINR of the QCL configured in the TCI state by a third preset threshold; the quality of the first beam is less than the fourth preset threshold; the quality of at least one second beam is greater than the quality of the first beam by a fifth preset threshold; the quality of the second beam is greater than the sixth preset threshold. In practical applications, the preset condition may be referred to as the first condition.

[0199] Accordingly, the embodiment of the present application also provides a communication method, such as Figure 3 As shown, Figure 3 This is a flow chart of another communication method according to an embodiment of the present application, which is applied to a network device, including:

[0200] Step 301: When a terminal determines that a preset condition is met, first information sent by the terminal is received, where the first information is used to indicate a measurement result of the terminal.

[0201] It should be noted that the network devices can be determined according to actual conditions and are not limited here. As an example, the network devices can be any network-side devices, such as a base station.

[0202] The preset condition can be determined according to the specific situation and is not limited here. As an example, the preset condition may include at least one of the following: the RSRP or SINR of the RS or SSB of the QCL configured in the TCI state is less than the first preset threshold; the RSRP or SINR of the preconfigured first RS is greater than the second preset threshold; the RSRP or SINR of the preconfigured first SSB is greater than the second preset threshold; the RSRP or SINR of at least one of the preconfigured first RS or the preconfigured first SSB is greater than the RSRP or SINR of the QCL configured in the TCI state by a third preset threshold; the quality of the first beam is less than the fourth preset threshold; the quality of at least one second beam is greater than the quality of the first beam by a fifth preset threshold; the quality of the second beam is greater than the sixth preset threshold. In practical applications, the preset condition may be referred to as the first condition. When the terminal determines that the preset condition is satisfied, it may be when the terminal determines that the first condition is satisfied.

[0203] The first information can be determined based on specific circumstances and is not limited herein. As an example, the first information can include at least one of the following: CRI; SSBID; TCI state ID; RSRP; SINR; event identifier; and no alternative RS. In practical applications, sending the first information to the network device can include sending a CRI, SSBID, TCI state ID, RSRP, SINR, or event identifier to the network device.

[0204] The first information is used to indicate a measurement result of the terminal. The measurement result may be determined according to specific circumstances and is not limited here. As an example, the measurement result may be a measurement result of the current beam.

[0205] In an embodiment of the present application, when a terminal determines that a preset condition is met, the terminal receives first information sent by the terminal indicating the terminal's measurement result. That is, the terminal can trigger the measurement result of the beam reporting process. For example, if the current beam quality deteriorates, the UE has a better and more timely understanding of the beam quality change. The beam reporting process initiated by the UE allows the network device to obtain more timely beam reports, while reducing reporting overhead and implementing the beam reporting process triggered by the terminal.

[0206] In one embodiment, the preset condition includes at least one of the following:

[0207] The reference signal RS or synchronization signal of the quasi-co-located QCL and the reference signal received power RSRP or signal-to-noise ratio SINR of the physical broadcast channel block SSB configured in the transmission configuration indication state TCI state are less than a first preset threshold;

[0208] The RSRP or SINR of the preconfigured first RS is greater than a second preset threshold;

[0209] The RSRP or SINR of the preconfigured first SSB is greater than a second preset threshold;

[0210] The RSRP or SINR of at least one of the preconfigured first RS or the preconfigured first SSB is greater than the reference signal received power RSRP or signal-to-noise ratio SINR of the RS or SSB of the quasi-co-location QCL configured in the transmission configuration indication state TCI state, which is greater than a third preset threshold;

[0211] The quality of the first beam is less than a fourth preset threshold;

[0212] The quality of at least one second beam is greater than the quality of the first beam by a fifth preset threshold;

[0213] The quality of the second beam is greater than a sixth preset threshold.

[0214] In the embodiment of the present application, the first preset threshold, the second preset threshold, the third preset threshold, the fourth preset threshold, the fifth preset threshold, and the sixth preset threshold can all be determined according to specific circumstances and are not limited here. The first preset threshold, the second preset threshold, the third preset threshold, the fourth preset threshold, the fifth preset threshold, and the sixth preset threshold can all be the same or different. In actual applications, the first preset threshold, the second preset threshold, the third preset threshold, the fourth preset threshold, the fifth preset threshold, and the sixth preset threshold can all be referred to as thresholds.

[0215] The first beam and the second beam may be determined according to specific circumstances and are not limited here. As an example, the first beam may be the current beam; the second beam may be a new beam, and the new beam may be L1-RSRP.

[0216] In practical applications, if the quality of the first beam is less than the fourth preset threshold, it can be understood that the quality of the current beam is worse than the threshold. If the quality of at least one second beam is greater than the quality of the first beam by a fifth preset threshold, it can be understood that the quality of at least one new beam (e.g., L1-RSRP) is better than the quality of the current beam by a threshold. If the quality of the second beam is greater than the sixth preset threshold, it can be understood that the quality of the new beam is better than the threshold.

[0217] As an example, the preset condition can be referred to as the first condition, and the first condition may include Event-1: Quality of the current beam is worse than a certain threshold (i.e., Event-1: the quality of the current beam is worse than a threshold). Event-2: Quality of at least one new beam, such as L1-RSRP, becomes a threshold value better than the current beam (i.e., Event-2: the quality of at least one new beam (such as L1-RSRP) is better than the quality of the current beam than the threshold). Event-3: Quality of a new beam is better than a certain threshold (i.e., Event-3: the quality of a new beam is better than a certain threshold). Event-4: Quality of the current beam is worse than a threshold 1, and quality of atleast one new beam is better than a threshold 2 (i.e., Event-4: the quality of the current beam is worse than a threshold, and the quality of at least one new beam is better than the threshold).

[0218] In one embodiment, the first information includes at least one of the following:

[0219] CRI;

[0226] In this embodiment, the RSRP may be determined according to specific circumstances and is not limited herein. As an example, the RSRP may include L1-RSRP, filtered RSRP, L3-RSRP, and the like.

[0227] The SINR may be determined according to specific circumstances and is not limited here. As an example, the SINR may include L1-SINR, filtered SINR, L3-SINR, and the like.

[0228] In actual applications, the terminal sending the first information to the network device may be the terminal sending CRI, SSBID, TCI state ID, RSRP, SINR, event identifier, no alternative RS, etc. to the network device. As an example, the terminal sends a new CRI / SSBID or TCI state ID to the network to indicate that the network expects the beam to be switched to the reported CRI / SSBID or TCI state to be updated to the TCI state ID.

[0229] In one embodiment, the method further comprises:

[0231] receiving a second RACH or a second SR sent by the terminal to indicate the first information reported by the terminal on a third PUSCH or a third PUCCH.

[0232] In this embodiment, the first RACH and the first SR can be determined based on actual conditions and are not limited here. As an example, the first RACH can be a dedicated RACH resource; the first SR can be a dedicated SR request. The receiving of the first RACH or first SR requesting a second PUSCH or a second PUCCH sent by the terminal and reporting the first information on the second PUSCH or the second PUCCH can be understood as the network device receiving the dedicated RACH resource or the dedicated SR requesting a second PUSCH or a second PUCCH sent by the terminal and reporting the first information on the second PUSCH or the second PUCCH.

[0233] The second RACH and the second SR can be determined based on actual conditions and are not limited here. As an example, the second RACH can be a dedicated RACH resource; the second SR can be a dedicated SR request. The receiving of the first information reported by the terminal on the third PUSCH or the third PUCCH by the second RACH or the second SR sent by the terminal can be understood as the network device receiving the dedicated RACH resource or the dedicated SR request sent by the terminal to instruct the terminal to report the first information on the third PUSCH or the third PUCCH.

[0234] In actual applications, when there are PUSCH resources, the terminal directly reports the first information on the PUSCH, and the network device receives the first information reported by the terminal directly on the PUSCH; when there is no PUSCH scheduling, the terminal first sends a dedicated RACH resource or a dedicated SR to request a PUSCH resource, and then reports the first information on the PUSCH, and the network device receives the first information reported by the terminal on the PUSCH.

[0235] In one embodiment, the method further comprises:

[0236] receiving a first parameter and a second parameter reported by the terminal;

[0237] When the value of the first parameter is 1, the second parameter is used to indicate a CRI or SSBID or TCI state ID or SINR or RSRP or event identifier, where the CRI or SSBID corresponds to the CSI-RS and SSB in the first resource set;

[0238] When the first parameter takes a value of 0, the second parameter is used to indicate that there is no alternative reference signal or the second parameter bit field is reserved.

[0239] In this embodiment, the first parameter and the second parameter can be determined according to actual conditions and are not limited here. As an example, the value of the first parameter can include 0 or 1. The second parameter can be an indicator parameter.

[0240] The correspondence between the CRI or SSBID and the CSI-RS and SSB in the first resource set can be understood as the existence of a correspondence between the CRI or SSBID and the CSI-RS and SSB in the first resource set.

[0241] In actual applications, RRC separately configures the CSI-RS / SSB resource set for UE-triggered beam management measurement, and adds a new MAC CE; when the first parameter = 1, the CRI / SSBID field indicates that the CRI / SSBID represents the RS selected by the terminal from the CSI-RS / SSB resource set, and reports the L1-RSRP / L1-SINR of the indicated RS (optional). When the first parameter = 0, it indicates no candidate RS or the second parameter bit field is reserved.

[0242] In one embodiment, the method further comprises:

[0243] receiving an association between the first information reported by the terminal and a channel state information reporting identifier, a channel state information resource configuration, or a channel state information resource set;

[0245] When the value of the first parameter is 1, the second parameter is used to indicate CRI or SSBID or TCI state ID or SINR or RSRP or event identifier;

[0246] When the first parameter takes a value of 0, the second parameter is used to indicate that there is no alternative reference signal or the second parameter bit field is reserved.

[0247] In this embodiment, the channel state information reporting identifier, channel state information resource configuration, or channel state information resource set can be determined based on actual conditions and is not limited here. As an example, the channel state information reporting identifier can be recorded as CSI reporting; the channel state information resource configuration can be recorded as CSI resource setting; and the channel state information resource set can be recorded as a CSI-RS / SSB resource set.

[0248] The association relationship can be determined according to actual conditions and is not limited here. As an example, the association relationship can be recorded as CRI / SSBID.

As an example, the value of the first parameter can include 0 or 1. The second parameter can be an indication parameter.

[0250] In actual applications, a new MAC CE is added, and the MAC CE is associated with one CSI reporting or CSIresource setting. The CRI / SSBID reported in the MAC CE indicates the X CRI / SSBIDs in the CSI-RS / SSB resource set corresponding to the associated CSI reporting or CSI resource setting, and reports the L1-RSRP / L1-SINR corresponding to the CRI / SSBID (optional). When the first parameter = 1, the CRI / SSBID field indicates that the CRI / SSBID represents the RS selected by the terminal from the CSI-RS / SSB resource set, and reports the L1-RSRP / L1-SINR of the indicated RS (optional). When the first parameter = 0, it indicates no candidate RS or the second parameter bit field is reserved.

[0251] In one embodiment, the method further comprises:

[0252] receiving a first parameter and a second parameter reported by the terminal;

[0253] When the value of the first parameter is 1, the second parameter is used to indicate CRI or SSBID or TCI state ID or SINR or RSRP or event identifier;

[0254] When the first parameter takes a value of 0, the second parameter is used to indicate that there is no alternative reference signal or the second parameter bit field is reserved.

[0255] The first parameter and the second parameter can be determined according to actual conditions and are not limited here. As an example, the value of the first parameter can include 0 or 1. The second parameter can be an indicator parameter.

[0256] In actual applications, a new MAC CE is added, and the MAC CE is pre-configured to associate one CSI reporting or CSI resource setting. The CRI / SSBID reported in the MAC CE indicates the X CRI / SSBIDs in the CSI-RS / SSB resource set corresponding to the associated CSI reporting or CSI resource setting, and reports the L1-RSRP / L1-SINR corresponding to the CRI / SSBID (optional). When the first parameter = 1, the CRI / SSBID field indicates that the CRI / SSBID represents the RS selected by the terminal from the CSI-RS / SSB resource set, and reports the L1-RSRP / L1-SINR of the indicated RS (optional). When the first parameter = 0, it indicates no candidate RS or the second parameter bit field is reserved.

[0257] In one embodiment, the first information includes a TCI state ID or no alternative reference information; and the method further includes:

[0258] receiving the TCI state ID reported by the terminal; the TCI state ID is used to represent the target TCI state ID that the terminal expects to apply; or,

[0259] The no alternative reference signal information reported by the terminal is received; the no alternative reference signal information is used to indicate that no alternative reference signal meets the preset condition.

[0260] In this embodiment, the first information includes TCI state ID; the TCI state ID is used to represent the target TCI state ID that the terminal expects to apply; receiving the TCI state ID reported by the terminal can be understood as a network device receiving a new TCI state ID reported by the terminal, and the new TCI state ID is used to indicate that the network expects the beam to switch to the reported TCI state and update to the TCI state ID.

[0261] The first information includes no alternative reference information; the no alternative reference information is used to characterize that no alternative reference signal meets the preset condition; wherein, the preset condition can be determined according to the specific situation and is not limited here. As an example, the preset condition may include at least one of the following: the RSRP or SINR of the RS or SSB of the QCL configured in the TCI state is less than the first preset threshold; the RSRP or SINR of the preconfigured first RS is greater than the second preset threshold; the RSRP or SINR of the preconfigured first SSB is greater than the second preset threshold; the RSRP or SINR of at least one of the preconfigured first RS or the preconfigured first SSB is greater than the RSRP or SINR of the QCL configured in the TCI state by a third preset threshold; the quality of the first beam is less than the fourth preset threshold; the quality of at least one second beam is greater than the quality of the first beam by a fifth preset threshold; the quality of the second beam is greater than the sixth preset threshold. In practical applications, the preset condition may be referred to as the first condition.

[0262] For ease of understanding, the example communication method of this application is specifically an uplink terminal feedback method. When the terminal determines that the first condition is met (for example, the L1-RSRP of the reference RS of the QCL configured in the TCI state is less than a certain threshold value), the terminal sends a new CRI / SSBID or TCI state ID to the network to indicate that the network expects the beam to switch to the reported CRI / SSBID or TCI state to update to the TCI stateID. The terminal reports the CRI / SSBID or TCIstate ID on PUSCH. This patent focuses on how to report or TCI state ID, or CRI / SSBID, and the corresponding L1-RSRP / L1-SINR (optional) on PUSCH.

[0263] The first condition may include the following:

[0264] Event-1: Quality of the current beam is worse than a certain threshold (i.e., Event-1: The quality of the current beam is worse than the threshold).

[0265] Event-2: Quality of at least one new beam, such as L1-RSRP, becomes threshold value better than the current beam (i.e., Event-2: The quality of at least one new beam (such as L1-RSRP) is better than the threshold value).

[0266] Event-3: Quality of a new beam is better than a certain threshold (i.e., Event-3: The quality of the new beam is better than a certain threshold).

[0267] Event-4: Quality of the current beam is worse than a threshold 1, and quality of at least one new beam is better than a threshold 2 (i.e., Event-4: The quality of the current beam is worse than the threshold, and the quality of at least one new beam is better than the threshold).

[0268] Example 1: Reporting the CRI / SSBID or TCI state ID in the MAC CE of a Regular / periodic long BSR (Buffer Status Report):

[0269] 1) When at least one LCG_i=0, after the buffer size field corresponding to LCG_i=1 ends, the remaining bit field is used to report the CRI / SSBID or TCI state ID. When there are more than or equal to X LCG_i=0, a maximum of X CRI / SSBIDs or TCI state IDs can be reported or the first parameter indicates no candidate RS. The value of X can be configured by the network side, but when the bit resources of the BSR are insufficient, the number of CRI / SSBIDs or TCI state IDs reported is determined based on the remaining bits of the BSR. This content can be combined with Figure 1 Understand.

[0270] 2) For the network side, if at least one LCG_i=0, and the bit field after the end of the buffer size field corresponding to LCG_i=1 is not all 0, it means that the remaining bit field reports the CRI / SSBID or TCI state ID corresponding to the beam management resource set triggered by the terminal, or the first parameter indicates no candidate RS.

[0271] 3) If the CRI / SSBID or TCI state ID is reported in the BSR, there is no need to schedule PUSCH to report the CRI / SSBID or TCI state ID.

[0272] Example 2: When PUSCH resources are available, the report is directly sent on PUSCH; when there is no PUSCH scheduling, the terminal first sends dedicated RACH resources or dedicated SR to request PUSCH resources, and then reports on PUSCH:

[0273] 1) Option 1: RRC configures a separate CSI-RS / SSB resource set for UE-triggered beam management measurements, adding MAC CE:

[0274] a) When the first parameter = 1, the CRI / SSBID field indicates that the terminal selects the RS from the CSI-RS / SSB resource set, and reports the L1-RSRP / L1-SINR of the indicated RS (optional)

[0275] b) When the first parameter = 0, it indicates no candidate RS.

[0276] This content can be understood in conjunction with Table 1, which is a schematic table of the first parameter of the embodiment of the present application.

[0281] 2) Option 2: Add a new MAC CE, and the MAC CE is associated with 1 CSI reporting or CSI resource setting. The CRI / SSBID reported in the MAC CE indicates the X CRI / SSBIDs in the CSI-RS / SSB resource set corresponding to the associated CSI reporting or CSIresource setting, and reports the L1-RSRP / L1-SINR corresponding to the CRI / SSBID (optional).
