Patent Application
20240284231
This application pertains to the field of communications technologies, and specifically relates to a reporting method and apparatus, and a terminal.
In a related mobility measurement technology, all measurement results of beam measurement and cell measurement of neighboring cells can be reported only at Layer 3 (L3), and are limited to a Synchronization Signal/Physical Broadcast Channel (SS/PBCH) block Measurement Timing Configuration (SMTC). Because the measurement results reported at layer 3 are obtained through temporal smoothing filtering of layer 1 measurement results, it takes a network-side device a long time to obtain the measurement results. Consequently, real-time performance of mobility management is poor.
Embodiments of this application provide a reporting method and apparatus, and a terminal.
According to a first aspect, a reporting method is provided and includes:
According to a second aspect, a reporting apparatus is provided and includes:
According to a third aspect, a terminal is provided. The terminal includes a processor, a memory, and a program or instructions stored in the memory and capable of running on the processor. When the program or instructions are executed by the processor, the steps of the reporting method according to the first aspect are implemented.
According to a fourth aspect, a terminal is provided. The terminal includes a processor and a communication interface. The processor is configured to perform layer 1 measurement. The communication interface is configured to report a layer 1 measurement result in a case that the layer 1 measurement result meets a first condition corresponding to an event.
According to a fifth aspect, a readable storage medium is provided. The readable storage medium stores a program or instructions. When the program or instructions are executed by a processor, the reporting method according to the first aspect is implemented.
According to a sixth aspect, a chip is provided. The chip includes a processor and a communication interface. The communication interface is coupled to the processor. The processor is configured to run a program or instructions to implement the method according to the first aspect.
According to a seventh aspect, a computer program or program product is provided. The computer program or program product is stored in a non-transitory storage medium. The program or program product is executed by at least one processor to implement the steps of the reporting method according to the first aspect.
In the embodiments of this application, the terminal performs the layer 1 measurement, and in the case that the layer 1 measurement result meets the first condition, the terminal reports the layer 1 measurement result. In comparison with conventional reporting through layer 3, in the reporting method provided in this application, there is no need to obtain a layer 3 measurement result through temporal smoothing filtering of the layer 1 measurement result and then report the measurement result at layer 3. Instead, the measurement result can be directly reported at layer 1. Therefore, the network-side device can obtain the measurement result as early as possible, and real-time performance of mobility management is improved. In addition, in comparison with periodic reporting of the layer 1 measurement result, in the reporting method provided in this application, the layer 1 measurement result can be reported only when the layer 1 measurement result meets the first condition corresponding to the event configured by the network-side device. Therefore, reporting resource overheads can be reduced, and flexibility of scheduling by a base station is improved.

A reporting method and apparatus, and a related device provided in embodiments of this application are hereinafter described in detail by using some embodiments and application scenarios thereof with reference to the accompanying drawings.
Step 201: A terminal performs layer 1 measurement.
Step 202: In a case that a layer 1 measurement result meets a first condition, the terminal reports the layer 1 measurement result, where the first condition corresponds to an event configured by a network-side device.
It should be noted that layer 1 refers to a physical layer, and that layer 2 refers to a Media Access Control (MAC), or Radio Link Control (RLC), or Packet Data Convergence Protocol (PDCP) layer, and layer 3 refers to a Radio Resource Control (RRC) layer.
In some embodiments, the first condition includes any one of the following:
It should be noted that the first configuration information is information configured by the network-side device, and that the first measurement resource set or the second measurement resource set is determined by the terminal based on the first configuration information by classifying measurement resources configured by the network-side device. For example, if the network-side device configures a plurality of measurement resources, the terminal may classify the plurality of measurement resources into the first measurement resource set and/or the second measurement resource set based on the first configuration information. In a case that the first condition includes the first measurement resource set and the second measurement resource set, the first measurement resource set and the second measurement resource set are determined by the terminal based on the first configuration information by classifying the measurement resources configured by the network-side device.
In this embodiment of this application, the event is an event configured by the network-side device. In the case that the layer 1 measurement result meets the first condition corresponding to the event, the terminal reports the layer 1 measurement result. The first condition may be any one of the foregoing four conditions.
For example, the first measurement resource set is a measurement resource set of a neighboring cell, and the second measurement resource set is a measurement resource set of a current serving cell. When the terminal performs layer 1 measurement on a Reference Signal (RS) of the neighboring cell and an RS of the current serving cell, if a layer 1 measurement result of an RS in the measurement resource set of the neighboring cell is greater than a layer 1 measurement result of an RS in the measurement resource set of the current serving cell, it is considered that the layer 1 measurement result meets the first condition, and the terminal reports the layer 1 measurement result.
In some alternative embodiments, when the terminal performs layer 1 measurement on an RS of the neighboring cell and an RS of the current serving cell, if a layer 1 measurement result of at least one RS in the measurement resource set of the neighboring cell is greater than the first threshold, and a layer 1 measurement result of at least one RS in the measurement resource set of the current serving cell is less than the second threshold, it is considered that the layer 1 measurement result meets the first condition, and the terminal reports the layer 1 measurement result.
It may be understood that the first condition is any one of the foregoing four conditions, and that reporting of the layer 1 measurement result by the terminal may also be other implementations. Details are not described herein in this embodiment of this application.
It should be noted that the first threshold, the second threshold, the third threshold, and the fourth threshold may be configured by using RRC signaling or values preset by the network-side device, which are not specifically limited in this embodiment of this application.
For better understanding, the following describes some of the foregoing four conditions in detail.
Condition 1: A layer 1 measurement result of at least one RS in the first measurement resource set is greater than a layer 1 measurement result of an RS in the second measurement resource set. The RS in the first measurement resource set is a first RS, and the RS in the second measurement resource set is a second RS. Formulas for determining condition 1 are shown in the following table.
Mn is the layer 1 measurement result of the first RS. Mp is the layer 1 measurement result corresponding to the second RS. Ofn, Ocn, Ofp, and Ocp are offset values configured by the network for layer 1 measurement of an RS of each cell. Off is an offset value between cells. Hys is a hysteresis value configured to avoid a ping-pong effect. It should be noted that the configuration of all offset values and hysteresis values is optional. When not configured, their values are equal to 0.
Condition 2: A layer 1 measurement result of at least one RS in the first measurement resource set is greater than the first threshold, and a layer 1 measurement result of at least one RS in the second measurement resource set is less than the second threshold. The RS in the first measurement resource set is a first RS, and the RS in the second measurement resource set is a second RS. Formulas for determining condition 2 are shown in the following table.
Mn is the layer 1 measurement result of the first RS. Mp is the layer 1 measurement result corresponding to the second RS. Ofp and Ocp are offset values configured by the network for layer 1 measurement of an RS of each cell. Thresh1 is the first threshold. Thresh2 is the second threshold. Hys is a hysteresis value configured to avoid a ping-pong effect. It should be noted that the configuration of all offset values and hysteresis values is optional. When not configured, their values are equal to 0.
Condition 3: A layer 1 measurement result of at least one RS in the first measurement resource set is less than the third threshold. The RS in the first measurement resource set is a first RS, and the RS in the second measurement resource set is a second RS. Determining formulas are shown in the following table.
Mn is the layer 1 measurement result of the first RS. Ofn and Ocn are offset values configured by the network for layer 1 measurement of an RS of each cell. Thresh3 is the first threshold. Hys is a hysteresis value configured to avoid a ping-pong effect. It should be noted that the configuration of all offset values and hysteresis values is optional. When not configured, their values are equal to 0.
In this embodiment of this application, the first measurement resource set and the second measurement resource set are determined by the terminal based on the first configuration information by classifying the measurement resources configured by the network-side device. In some embodiments, the first configuration information includes at least one of the following:
In this embodiment of this application, depending on different events, the classification of the first measurement resource set and the second measurement resource set also varies. For example, the first configuration information includes the cell list information. If the event is defined as “beam quality of the neighboring cell is better than beam quality of the current serving cell,” the first measurement resource set is the measurement resource set of the neighboring cell (such as an RS set), and the second measurement resource set is the measurement resource set of the current serving cell.
In some alternative embodiments, the first configuration information includes the at least one Transmission Configuration Indicator (TCI) state currently activated by the network-side device. If the event is defined as “quality of a candidate beam is better than quality of a currently activated beam,” the first measurement resource set includes RSs of all the measurement resources configured by the network-side device except a Quasi Co-Location (QCL) source RS (including at least a QCL Type-D RS) corresponding to the at least one TCI state currently activated by the network-side device, and the second measurement resource set includes the QCL source RS (including at least the QCL Type-D RS) corresponding to the at least one TCL state currently activated by the network-side device.
In some alternative embodiments, the first configuration information includes the TCL state of the control resource set 0 (CORESET #0). If the event is defined as “quality of a candidate beam is better than current beam quality of the CORESET #0,” the first measurement resource set includes RSs of all the measurement resources configured by the network-side device except a QCL source RS (including at least a QCL Type-D RS) corresponding to the TCL state of the CORESET #0, and the second measurement resource set may include the QCL source RS (including at least the QCL Type-D RS) corresponding to the TCL state of the CORESET #0.
In some alternative embodiments, the first configuration information includes the TCL state of the non-terminal-dedicated control resource set. If the event is defined as “quality of a candidate beam is better than quality of a currently activated beam in the non-terminal-dedicated control resource set,” the first measurement resource set includes RSs of all the measurement resources configured by the network-side device except a QCL source RS (including at least a QCL Type-D RS) corresponding to the TCL state of the non-terminal-dedicated control resource set, and the second measurement resource set includes the QCL source RS (including at least the QCL Type-D RS) corresponding to the TCL state of the non-terminal-dedicated control resource set.
In some alternative embodiments, the first configuration information includes the frequency configuration information of the measurement resource. If the event is defined as “beam quality of a frequency band 1 is higher than beam quality of a frequency band 2,” the first measurement resource set may be RSs in the frequency band 1 among all the measurement resources configured by the network-side device, and the second measurement resource set may be RSs in the frequency band 2 among all the measurement resources configured by the network-side device. The frequency band 2 may be a frequency band corresponding to the current serving cell.
In this embodiment of this application, the layer 1 measurement result includes at least one of a layer 1 measurement result of an RS of the current serving cell and a layer 1 measurement result of an RS of the neighboring cell. For example, the terminal performs layer 1 measurement on the RS of the current serving cell and the RS of the neighboring cell. The layer 1 measurement result reported by the terminal may be the layer 1 measurement result of the RS of the current serving cell and the layer 1 measurement result of the RS of the neighboring cell, or may include only the layer 1 measurement result of the RS of the current serving cell or the layer 1 measurement result of the RS of the neighboring cell.
A PCI associated with the RS of the neighboring cell is different from the PCI of the current serving cell.
In this embodiment of this application, the terminal performs the layer 1 measurement, and in the case that the layer 1 measurement result meets the first condition corresponding to the event, the terminal reports the layer 1 measurement result. In comparison with conventional reporting through layer 3, in the reporting method provided in this application, there is no need to obtain a layer 3 measurement result through temporal smoothing filtering of the layer 1 measurement result and then report the measurement result at layer 3. Instead, the measurement result can be directly reported at layer 1. Therefore, the network-side device can obtain the measurement result as early as possible, and real-time performance of mobility management is improved. In addition, in comparison with periodic reporting of the layer 1 measurement result, in the reporting method provided in this application, the layer 1 measurement result can be reported only when the layer 1 measurement result meets the first condition corresponding to the event. Therefore, reporting resource overheads can be reduced, and flexibility of scheduling by a base station is improved.
In this embodiment of this application, the network-side device configures, for the terminal, configuration information for triggering a plurality of events; the terminal performs the layer 1 measurement; in a case that the layer 1 measurement result meets a first condition corresponding to any one of the plurality of events configured by the network-side device, the terminal triggers reporting of the layer 1 measurement result; and the network-side device determines, based on received report information, the first condition corresponding to which event is met by the layer 1 measurement result. For example, the terminal sends, to the network-side device, a RACH resource associated with an RS with a greatest layer 1 measurement result; and if the RS associated with the RACH resource belongs to the neighboring cell, the network-side device may determine, after receiving the RACH resource, that an event met by the reporting is that beam quality of an RS of the neighboring cell is higher than beam quality of an RS of the current serving cell.
In some alternative embodiments, the network-side device configures, for the terminal, configuration information for triggering only one event; and the terminal performs the layer 1 measurement and determines, based on a first condition corresponding to the event configured by the network-side device, whether to report the layer 1 measurement result.
In some embodiments, step 201 may include:
In this embodiment of this application, after receiving the signaling configured by the network-side device, the terminal may perform the layer 1 measurement based on the configuration information of the measurement resource carried in the signaling, and in the case that the layer 1 measurement result meets the first condition corresponding to the event, the terminal triggers reporting of the layer 1 measurement result.
In some embodiments, the configuration information of the measurement resource includes at least one of the following:
For example, the configuration information of the measurement resource includes the configuration information of the RS. The RS may include a synchronization Synchronization Signal and PBCH block (SSB), a Channel State Information Reference Signal (CSI-RS) for mobility, a CSI-RS for beam management, a CSI-RS for tracking, a Sounding Reference Signal (SRS), or the like.
In some alternative embodiments, the configuration information of the measurement resource may further include the cell list information, or include the configuration information of the SMTC, or include the cell list information and the configuration information of the RS, or the like, which is not exhaustively listed herein in this application.
It should be noted that the configuration information of the measurement resource may be configured by using a new higher layer parameter, or may be configured by using an existing higher layer parameter, such as a higher layer parameter MeasObjectNR.
In some embodiments, the signaling configured by the network-side device further includes configuration information of a beam report, and based on the configuration information of the beam report, the terminal can determine beam information and a reporting resource for reporting the layer 1 measurement result.
In some embodiments, the configuration information of the beam report includes at least one of the following:
The measurement resource associated with the beam report includes at least a QCL source RS (QCL source RS) corresponding to at least one TCI state currently activated by the network-side device.
It should be noted that the terminal determines whether the layer 1 measurement result meets the first condition corresponding to the event. The event may be determined based on the event trigger configuration information. The event trigger configuration information is carried in the signaling sent by the network-side device. In other words, the terminal determines, based on the event configured by the network-side device, whether the layer 1 measurement result meets the first condition corresponding to the event.
In some embodiments, the event trigger configuration information includes at least one of the following:
The event trigger threshold may be a threshold for triggering an event. For example, when a threshold for triggering event A is reached, the terminal triggers reporting of the layer 1 measurement result in a case that the terminal determines that the layer 1 measurement result meets a first condition corresponding to event A. The duration of the event trigger timer may be duration of a timer for triggering an event. For example, when duration of a timer for triggering event B is reached, the terminal triggers reporting of the layer 1 measurement result if the terminal determines that the layer 1 measurement result meets a first condition corresponding to event B. The maximum value of the event trigger counter may be a maximum value of a counter for triggering an event. The event-triggered reporting interval may be an interval of reporting triggered by an event. Content included in the event trigger configuration information may be in a plurality of forms, which are not exhaustively listed in this embodiment of this application.
In some embodiments, one event corresponds to one piece of event trigger configuration information, or a plurality of events correspond to one piece of event trigger configuration information.
In this embodiment of this application, the beam information pair includes at least one of the following: a layer 1 measurement result, a measurement resource identifier, a cell identity, and frequency-related information.
In some embodiments, the layer 1 measurement result may include layer 1 Reference Signal Received Power (RSRP), layer 1 Reference Signal Received Quality (RSRQ), a layer 1 Signal to Interference plus Noise Ratio (SINR), or the like.
In some embodiments, the measurement resource identifier may include a CSI-RS Resource Indicator (CRI), an SSB Resource Indicator (SSBRI), a Sounding Reference Signal Resource Indicator (SRSRI), or the like.
In some embodiments, the cell identity may be a PCI, an indication of configuration information of the neighboring cell, or the like. The cell identity includes either of the physical cell identifier and an indication of related configuration information of the neighboring cell through bit mapping.
In some embodiments, the beam information pair may include the frequency-related information only for inter-frequency measurement, and the frequency-related information may be information about a frequency of the measurement resource or indication information indicating a frequency of the measurement resource.
In some embodiments, the quantity of beam information pairs is related to a capability of the terminal. For example, the quantity of beam information pairs is configured by the network-side device based on the capability of the terminal; and the maximum quantity of cells allowed to be reported may also be configured by the network-side device based on the capability of the terminal.
In some embodiments, the reporting resource includes at least one of the following: a configured grant and a Random Access Channel (RACH) resource.
The RACH resource is associated with the measurement resource associated with the beam report. For example, all SSBs corresponding to each PCI are associated with a same RACH resource, or different SSBs are associated with different RACH resources.
In some embodiments, at least one of the following operations is performed on at least one of the configuration information of the beam report and the configuration information of the measurement resource by using a Media Access Control Control Element (MAC CE): modification, deletion, addition, and update.
In some embodiments, the configuration information of the measurement resource and the configuration information of the beam report are separately encapsulated, and the measurement resource is associated with the beam report based on measurement configuration information.
For example, configuration information of all measurement resources is configured in a higher layer parameter MeasObjectNRList_r17, and configuration information of each measurement resource corresponds to an element MeasObjectNR_r17 in the MeasObjectNRList_r17 by using a MeasObjectNRId_r17. Similarly, configuration information of all beam reports is configured in a higher layer parameter ReportConfigList_r17, and configuration information of each beam report corresponds to an element ReportConfig_r17 in the ReportConfigList_r17 by using a ReportConfigld_r17. All measurement configuration information is configured in a higher layer parameter MeasConfigList_r17, each piece of measurement configuration information corresponds to an element MeasConfig_r17 in the MeasConfigList_r17 by using a MeasId_r17, and each MeasConfig_r17 includes at least one MeasId_r17, one MeasObjectNRId_r17, and one ReportConfigId_r17.
In some alternative embodiments, the configuration information of the beam report includes the configuration information of the measurement resource associated with the beam report. For example, in the configuration information of the beam report, one or more higher layer parameters are used to indicate all or some measurement resources of the current serving cell and the neighboring cell. For example, the corresponding resource is associated by using CSI-ReportConfig in the related art.
In this embodiment of this application, step 202 may include any one of the following:
For example, in an implementation, the terminal performs the layer 1 measurement, and in the case that the layer 1 measurement result meets the first condition corresponding to the event, the terminal triggers, through the physical layer, reporting of the layer 1 measurement result.
For example, in another implementation, the terminal may trigger, through the MAC layer, reporting of the layer 1 measurement result.
For example, in an implementation, the terminal performs the layer 1 measurement; when the physical layer of the terminal determines that the layer 1 measurement result always meets the first condition within the event-triggered reporting interval, the terminal reports the corresponding trigger indication of the event to the MAC layer through the physical layer; the MAC layer counts the trigger indication of the event by using the event trigger counter; and when the count value of the event trigger counter exceeds the maximum value preset or configured by the network-side device, the terminal triggers, through the MAC layer, reporting of the layer 1 measurement result.
It should be noted that, in a case that a second condition is met, the count value of the event trigger counter is cleared to zero, and the second condition includes any one of the following:
Each time the MAC layer receives a trigger indication of the event, the event trigger timer restarts timing.
For example, in another implementation, the terminal performs the layer 1 measurement; the terminal reports the layer 1 measurement result to the MAC layer of the terminal; and in a case that the MAC layer determines that the layer 1 measurement result always meets the first condition within the preset time period, the terminal triggers, through the MAC layer, reporting of the layer 1 measurement result. That the layer 1 measurement result always meets the first condition within the preset time period may be that the layer 1 measurement result continuously meets the first condition within the preset time period. For example, the preset time period includes four continuous measurement periods. It is considered that the layer 1 measurement result always meets the first condition within the preset time period, and the terminal triggers, through the MAC layer, reporting of the layer 1 measurement result, only when the layer 1 measurement result meets the first condition within all of the four measurement periods. If the layer 1 measurement result does not meet the first condition within any one of the four measurement periods, it is considered that the layer 1 measurement result does not always meet the first condition within the preset time period, and the terminal does not trigger reporting of the layer 1 measurement result.
In another implementation, the terminal performs the layer 1 measurement; the terminal reports the layer 1 measurement result to the MAC layer of the terminal; and in a case that the MAC layer determines that the layer 1 measurement result always fails to meet the first condition within the preset time period, the terminal triggers, through the MAC layer, reporting of the layer 1 measurement result. For example, the preset time period includes four continuous measurement periods. It is considered that the layer 1 measurement result always fails to meet the first condition within the preset time period, and the terminal triggers, through the MAC layer, reporting of the layer 1 measurement result, only when the layer 1 measurement result fails to meet the first condition within all of the four measurement periods. If the layer 1 measurement result meets the first condition within any one of the four measurement periods, it is considered that the layer 1 measurement result does not always fail to meet the first condition within the preset time period, and the terminal does not trigger reporting of the layer 1 measurement result.
In some embodiments, that the terminal reports the layer 1 measurement result includes:
In some embodiments, that the terminal selects M layer 1 measurement results includes any one of the following:
The fifth threshold and the sixth threshold may be configured by using RRC signaling or values preset by the network-side device.
In some embodiments, the preset rule includes any one of the following:
In some embodiments, the reporting, on a first resource, beam information corresponding to the M layer 1 measurement results includes either of the following:
In a case that the terminal maps the beam information corresponding to the M layer 1 measurement results to the UCI, and reports by using the UCI, a field may be further added to the UCI to indicate that the UCI is beam information reported based on event triggering, for example, a beam report transmitted by using a PUCCH or an Uplink grant (UL grant).
In this embodiment of this application, that the terminal selects M layer 1 measurement results, and reports, on a first resource, beam information corresponding to the M layer 1 measurement results, where the beam information includes M beam information pairs, and the M beam information pairs are differentially reported, may include:
In some embodiments, the first resource includes any one of the following:
The RACH resource configured by the network-side device and associated with the measurement resource is used for beam reporting between cells. For example, the terminal may select a RACH resource associated with a measurement resource with a best layer 1 measurement result for sending, to notify the network-side device that a corresponding event occurs. For example, if a reported RS belongs to the neighboring cell, the network-side device can also know that beam quality of the neighboring cell is higher than beam quality of the current serving cell.
The first resource includes the UL grant resource requested to be scheduled by using the PUCCH SR, and this may be intended for a case that no UL grant is available. The PUCCH SR may be a scheduling request used for event-triggered reporting, or may be shared with other SRs.
The first resource includes the information Msg_A or the information Msg_3 in the RACH process, and this may be intended for a case that no UL grant is available and that the PUCCH SR for event-triggered reporting is not configured. The RACH resource is associated with an RS with a greatest layer 1 measurement result in the current serving cell, or the RACH resource is associated with an RS with a greatest layer 1 measurement result among all the measurement resources configured by the network-side device.
In this embodiment of this application, the reporting, on a first resource, beam information corresponding to the M layer 1 measurement results further includes:
In this embodiment of this application, the terminal can measure the RS of the neighboring cell and the RS of the current serving cell through layer 1, determine whether the layer 1 measurement result meets the first condition corresponding to the event, and further selectively perform beam reporting. In comparison with periodic beam reporting, the reporting method provided in this application can improve effectiveness of the reported beam information and reduce energy consumption of the terminal. In addition, in comparison with conventional layer 3 reporting, the layer 1 based reporting method provided in this embodiment of this application enables the network-side device to obtain the beam quality of the neighboring cell as early as possible and perform cell handover in time, which is more conducive to terminal mobility management.
For better understanding, the technical solutions of the embodiments of this application are hereinafter described by using two embodiments.
