The terminal device may also be referred to as a terminal or UE for short, and those skilled in the art may understand its meaning.

[0038] The access network device 20 is a device deployed in the access network to provide wireless communication functions for the terminal device 10. The access network device 20 may include various forms of macro base stations, micro base stations, relay stations, APs (Access Points), etc. In systems using different wireless access technologies, the names of devices with access network device functions may be different. For example, in the 5G NR (New Radio) system, it is called gNodeB or gNB (Next Generation Node B). With the evolution of communication technology, the name "access network device" may change. For the convenience of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as access network devices. In some embodiments, a communication relationship can be established between the terminal device 10 and the core network network element 30 through the access network device 20. For example, in an LTE (Long Term Evolution) system, the access network device 20 may be an Evolved Universal Terrestrial Radio Access Network (EUTRAN) or one or more eNodeBs in the EUTRAN.

The technical solutions described in the embodiments of the present application may be applicable to LTE systems, 5G NR systems, and subsequent evolution systems of 5G NR systems (e.g., B5G (Beyond 5G) systems, 6G systems (6th Generation System, sixth generation mobile communication systems)), and other communication systems such as NB-IoT (Narrow Band Internet of Things) systems, which are not limited in this application.

[0042] In an embodiment of the present application, the network device can provide services for a cell, and the terminal device communicates with the network device through the transmission resources (for example, frequency domain resources, or spectrum resources) on the carrier used by the cell. The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0043] Before introducing the technical solutions of this application, we first introduce and explain some of the relevant technical knowledge involved in this application. The following related technologies can be combined with the technical solutions of the embodiments of this application as optional solutions, and they all fall within the scope of protection of the embodiments of this application. The embodiments of this application include at least part of the following contents.

[0044] 1) Energy saving of terminal equipment based on wake-up receiver

[0045] In order to further save power for UE, a wake-up receiver WUR is introduced in the relevant technology to receive the wake-up signal. The wake-up receiver has the characteristics of extremely low cost, extremely low complexity and extremely low power consumption, and it mainly receives the wake-up signal through an envelope detection-based method. Therefore, the wake-up signal WUS (Wake Up Signal) received by the wake-up receiver is different from the modulation method, waveform, etc. of the signal carried by the PDCCH (Physical Downlink Control Channel) defined in the standard. The wake-up signal is mainly an envelope signal that performs ASK (Amplitude Shift Keying) modulation on the carrier signal. The demodulation of the envelope signal is also mainly based on the energy provided by the wireless radio frequency signal to drive the low-power circuit, so it can be passive. The wake-up receiver can also be powered by the terminal device. Regardless of the power supply method, the receiver greatly reduces power consumption compared to the traditional receiver of the UE. The wake-up receiver can be combined with the UE as an additional module of the UE receiver, or it can be used as a wake-up function module of a UE alone.

[0046] The block diagram of the zero-power wake-up receiver system is shown in Figure 2. The wake-up receiver receives the wake-up signal and, if the UE needs to turn on the receiver, instructs the UE to turn on the main receiver. Otherwise, the UE's main receiver can be turned off.

[0047] The signal received by the wake-up receiver can be called a WUR signal, which adopts a relatively simple modulation method to meet the reception requirements of the wake-up receiver with extremely low power consumption and extremely low complexity. Among them, the wake-up signal WUS is one of the WUR signals. The method for generating the WUR signal, such as the wake-up signal in the related art, adopts OOK modulation. The modulation principle of OOK is to modulate the amplitude of the carrier signal to non-zero values ​​and zero values, corresponding to On and Off, respectively, to represent the information bit. OOK is also known as binary amplitude shift keying (2ASK). The OOK modulation process is shown in Figure 3.

[0048] The above-mentioned OOK signal is generated through multiple carriers, so it is called an MC-OOK signal. The generation of MC-OOK signals can adopt existing multi-carrier modulation such as OFDM (Orthogonal Frequency Division Multiplexing) modulation to generate OOK signals, which can maintain good compatibility with existing OFDM systems and reduce the transmitter complexity introduced to implement WUR signals. Figure 4 is a schematic diagram of MC-OOK signals generated by multiple carriers. By mapping the corresponding amplitude values ​​to multiple subcarriers in the frequency domain, the waveform of the time domain signal converted by IDFT (Inverse Discrete Fourier Transform) is similar to the waveform formed by ASK modulation, where bit 1 is represented by a high level of the signal and bit 0 is represented by a low level of the signal.

[0049] 2) RRM measurement

[0050] For wireless mobile communication systems, accurate measurement of cell quality and beam quality is fundamental to effective radio resource management and mobility management. For 5G NR, two main types of reference signals are currently considered for measurement: SSB and CSI-RS (Channel-State Information Reference Signal).

[0051] SMTC is the time domain resource configuration information for SSB measurements and is also an important new concept introduced in 5G NR measurement configuration. It is mainly used to configure a set of measurement time windows based on SSB measurements. The size, position, period and other parameters of the window can be adjusted through configuration parameters. An example is shown in Figure 5.

[0052] It should be noted that SMTC is configured separately for each frequency point. When the UE is making measurements, there is a set of SMTC configurations on each measurement frequency point to indicate the available measurement window information on that frequency point. However, this restriction is gradually being relaxed during protocol discussions. In related technologies, in order to match the different synchronization signal block periods of different cells, two sets of SMTC parameters are allowed to be configured for measurement of a given cell during connected state same-frequency measurements. For example, in addition to the basic SMTC configuration, a more dense set of measurement windows can be configured for use by the serving cell and the cells indicated in the specific cell list. Later, idle state measurements also expanded the maximum number of SMTC configurations on each frequency point to two to further meet the flexibility of network operations.

[0053] In addition, high-level signaling can indicate the specific configuration information of the specific measurement reference signal through the Reference Signal Config parameter. For SSB-based measurements, the SSB to be measured indication (ssb-ToMeasure) uses a bitmap to indicate the position information of the SSB actually transmitted in the SSB burst set. The UE can clearly know which SSB candidate positions actually transmit SSBs and which SSB candidate positions do not transmit SSBs through ssb-ToMeasure. The UE does not need to perform measurements at positions where SSBs are not transmitted, thereby achieving energy saving for the UE.

[0054] For CSI-RS-based measurements, the base station can configure one or more CSI-RS resources for the UE to measure through high-layer signaling. First, based on the cell, high-layer signaling can provide cell-level CSI-RS configuration parameters, such as the cell ID (Identity Document), the cell's measurement bandwidth, and resource density. Furthermore, since each cell can be configured with multiple CSI-RS resources, further parameter configuration also provides configuration information for each CSI-RS resource level, such as the specific CSI-RS index, the time and frequency domain location information occupied by the CSI-RS resource, and the sequence generation method.

[0055] The mobility management of UE in the NR system mainly includes the cell selection and reselection process in the RRC_IDLE (RRC idle state) or RRC_INACTIVE (RRC inactive state) state and the handover process of the connected UE.

[0056] 1. Mobility management in RRC_IDLE or RRC_INACTIVE state

[0057] For a UE in RRC_IDLE or RRC_INACTIVE state, the prerequisite for being able to camp on a cell is that the signal quality of the cell (including RSRP (Reference Signal Receiving Power) and RSRQ (Reference Signal Received Quality) measurement results) meets the cell selection S criterion. After selecting a suitable cell, the UE will continue to evaluate the cell reselection. The measurements performed for evaluating the cell reselection are divided and performed according to the reselection priority of each frequency point. Specifically:

[0058] For high-priority frequencies, neighbor cell measurements are always performed.

[0059] For the same-frequency point, when the RSRP and RSRQ values ​​of the serving cell are both higher than the same-frequency measurement threshold configured by the network, the UE can stop measuring the same-frequency neighbor cell; otherwise, the measurement must be performed.

[0060] For frequencies with the same or lower priority, when the RSRP and RSRQ values ​​of the serving cell are both higher than the inter-frequency measurement threshold configured by the network, the UE can stop measuring neighboring cells with the same or lower priority. Otherwise, measurements must be performed.

[0061] After obtaining multiple candidate cells through measurement, the process of determining the target cell for cell reselection is basically the same as that of the LTE system, and the principle of prioritizing reselection of cells on high-priority frequencies is adopted.

[0062] For cell reselection on a high-priority frequency, the signal quality must be above a certain threshold for a specified period of time, and the UE must camp on the source cell for at least 1 second.

[0063] For cell reselection on the same frequency and priority band, the R criteria (ordered by RSRP) must be met, the new cell signal quality must be better than the current cell for a specified period of time, and the UE must camp on the source cell for at least 1 second.

[0064] For cell reselection on a low-priority frequency, there must be no high-priority or same-priority cells that meet the requirements, the source cell signal quality must be below a certain threshold, the signal quality of the cell on the low-priority frequency must be above a certain threshold for a specified period of time, and the UE must camp on the source cell for at least 1 second.

[0065] During cell reselection on the same frequency and priority frequency, when multiple candidate cells meet the requirements, the LTE system selects the best cell as the target cell for reselection by sorting by RSRP. Considering that UEs in the NR system access cells via beams, to increase the probability of successful access via a good beam, the target cell must be determined based on both cell signal quality and the number of good beams. To achieve this, the NR system first selects the best cells with similar signal quality before selecting the target cell, and then selects the cell with the largest number of good beams as the target cell.

[0066] 2. Connected Mobility Management

[0067] The mobility management of connected UEs is mainly achieved through the handover process controlled by the network. The NR system inherits the handover process of the LTE system, which mainly includes three stages: handover preparation, handover execution and handover completion.

[0068] During the handover preparation phase, the source base station makes a handover decision after receiving the measurement report sent by the UE and initiates a handover request to the target base station. If the target cell accepts the request, it sends a handover response message to the source base station through the inter-base station interface. The message contains the configuration information of the target cell, that is, the handover command.

[0069] During the handover execution phase, the source base station sends a handover command to the UE. Upon receiving the handover command, the UE disconnects from the source cell and begins establishing downlink synchronization with the target cell. It then initiates a random access procedure to the target cell using the random access resources configured in the handover command and reports a handover completion message upon completion of the random access. While the UE is accessing the target cell, the source base station forwards the data packets received from the UPF to the target base station and sends the target base station information about the uplink and downlink data packet transmission and reception status within the source cell before the forwarding.

[0070] During the handover completion phase, the target eNB sends a path switch request to the AMF, requesting that the AMF switch the data packet transmission path from the UPF to the access network to the target eNB. Once the AMF responds to the request, indicating that the path switch is successful, the target eNB can instruct the source eNB to release the UE context information. At this point, the entire UE connection is switched to the target cell.

[0071] 3. Non-connected RRM measurement relaxation mechanism

[0072] Terminal devices in a non-connected state need to perform RRM measurements on the serving cell and other neighboring cells based on the network configuration to support mobility operations, such as cell reselection. In related technologies, for the sake of energy saving of terminal devices, when the channel quality of the terminal device in the serving cell is good, the terminal device may not start RRM measurements for the same frequency point and the same or lower priority different frequency / different technology frequency points. At the same time, the measurement interval for RRM measurements of high priority different frequency / different technology frequency points can be increased. Specifically:

[0073] When the RSRP of the terminal device on the serving cell is higher than the configured SIntraSearchP (a higher-layer configured threshold parameter) and the RSRQ of the terminal device on the serving cell is higher than SIntraSearchQ, the terminal device may not initiate RRM measurements for neighboring cells on the same frequency point.

[0074] When the RSRP of the terminal device on the serving cell is higher than SnonIntraSearchP and the RSRQ of the terminal device on the serving cell is higher than SnonIntraSearchQ, the terminal device may not initiate RRM measurements for inter-frequency and inter-system low-priority and equal-priority neighboring cells. At the same time, the terminal device may initiate relaxed RRM measurements for inter-frequency and inter-system high-priority frequencies.

[0075] For terminal devices that need to perform RRM measurements of neighboring cells, it is necessary to introduce a set of RRM measurement relaxation mechanisms for neighboring cells to further meet the power saving needs of terminal devices.

[0076] Related technologies have introduced two sets of measurement relaxation criteria for RRM measurements of non-connected terminal devices: the "terminal device is not at the cell edge" criterion and the "low mobility" criterion. Both criteria are based on the "cell-level" measurement results of the terminal device in the serving cell. The following describes these two criteria separately.

[0077] 1. “Terminal equipment is not located at the cell edge” principle

[0078] For this criterion, the network will configure an RSRP threshold and may also configure an RSRQ threshold. When the RSRP of the terminal device on the serving cell is greater than the RSRP threshold, and when the network has configured an RSRQ threshold, the RSRQ of the terminal device on the serving cell is greater than the RSRQ threshold, then the terminal device is considered to meet the "terminal device is not located at the cell edge" criterion.

[0079] The RSRP threshold configured by the network for the "terminal device is not at the cell edge" criterion must be smaller than SIntraSearchP and SnonIntraSearchP. If the network also configures the RSRQ threshold for the "terminal device is not at the cell edge" criterion, the RSRQ threshold for the "terminal device is not at the cell edge" criterion must be smaller than SIntraSearchQ and SnonIntraSearchQ.

[0080] 2. "Low Mobility" Principle

[0081] For this criterion, as shown in Figure 6, the network will configure the evaluation time T for RSRP changes. SearchDeltaP and RSRP change threshold S SearchDeltaP , when a period of time T SearchDeltaP The RSRP change of the terminal device in the serving cell is less than S SearchDeltaP , the terminal device is considered to meet the "low mobility" criterion.

[0082] It should be pointed out that the "low mobility" criterion has been enhanced in the relevant technology. The main change is the introduction of the second threshold SSearchDeltaP and the second TSearchDelta to support further relaxation of measurements for low mobility scenarios (such as stationary terminal devices or quasi-stationary terminal devices) (reflected in a larger scaling factor).

[0083] After completing cell selection / reselection, the terminal device needs to wait for at least a period of time TSearchDeltaP Normal RRM measurements are performed within the

[0084] For RRM measurements of frequencies with equal or lower priority, RRM measurement relaxation methods are defined for different RRM measurement relaxation criteria, as shown in Figure 7. The details are as follows:

[0085] When a terminal device meets the "low mobility" criterion, the terminal device uses a longer measurement interval when performing RRM measurements on neighboring cells. A fixed scaling factor is used to increase the measurement interval.

[0086] When the terminal device meets the "terminal device is not located at the cell edge" criterion, the terminal device uses a longer measurement interval when performing RRM measurements on neighboring cells. A fixed scaling factor is used to increase the measurement interval.

[0087] When a terminal device meets both the "low mobility" and "terminal device is not located at the cell edge" criteria, the terminal device's measurement interval for the same-frequency point, different-frequency point, and different access network point is increased to 1 hour.

[0088] 4. RRM measurement requirements for UE in RRC connected state

[0089] It includes intra-frequency measurement and inter-frequency measurement. Measurement without MG (Measurement Gap) mainly considers the SMTC period; while measurement with MG needs to consider the SMTC and MGRP (Measurement Gap Repetition Period) periods.

[0090] For L3 RRM measurements, the current related technology uses the following rules to determine whether an MG is required to perform measurements:

[0091] Intra-frequency SSB: When the UE indicates 'no-gap' via the intraFreq-needForGap flag, or when the SSB is within the UE's active Bandwidth Part (BWP), or when the current DL BWP is the initial DL BWP, the UE is capable of performing intra-frequency SSB measurements outside the MG. The relationship between the SMTC and the MG determines whether the actual measurement is within the MG.

[0092] ■For the MO (Measurement Object) of the same frequency SSB which may not require MG,

[0093] ◆When the associated SMTC and MG occasion do not overlap at all, use outside MG;

[0094] ◆When the associated SMTC and MG occasion partially overlap, use outside MG;

[0095] ◆When the associated SMTC and MG occasion completely coincide, use within MG;

[0096] For intra-frequency SSBs that may require an MG, only within-MG measurements are possible (the relationship between the SMTC and the MG is no longer considered). For inter-frequency SSBs, when the UE supports interFrequencyMeas-Nogap-r16, the network indicates interFrequencyConfig-NoGap-r16, and inter-frequency SSBs are within the active BWP, the UE is capable of performing inter-frequency measurements of the SSBs outside the MG. The relationship between the SMTC and the MG further determines whether the actual measurement needs to be performed within the MG.

[0097] ■For MO with different frequency SSB and no MG required,

[0098] When the associated SMTC and MG occasion do not overlap at all, and the above interFrequencyMeas-NoGap-r16 and interFrequencyConfig-NoGap-r16 conditions are met, the outside MG is used;

[0099] When the associated SMTC partially overlaps with the MG occasion, for UEs that support CA capabilities and meet the above interFrequencyMeas-NoGap-r16 and interFrequencyConfig-NoGap-r16 conditions, the outside MG is used;

[0100] ◆When the associated SMTC and MG occasion completely coincide, use within MG;

[0101] When the associated SMTC and MG occasion partially overlap, for UEs that do not support CA capabilities, within MG is used;

[0102] ■For MO with heterodyne SSB and which does not require MG, only within MG can be used.

[0103] 5. Connected RLM / BFD / BM measurement: BWP without restriction

[0104] Introduction

[0105] Bandwdith Part (BWP) operation without Restriction (FG 6-1a as referred in TR 38.822) is an optional feature introduced in Rel-15 for non-Redcap UEs, for the support of BWP operation without a Cell-Defining Synchronization Signal Block (CD-SSB). Due to unclear UE behavior on how to perform Beam Management (BM), Radio Link Monitoring (RLM) and Beam Failure Detection (BFD) operations, in the case where the UE was operating in a BWP that would not include the bandwidth (BW) of the SSB, four options were specified to complete the support of this feature. Since the UE behavior is not clear on how to perform Beam Management (BM), Radio Link Monitoring (RLM) and Beam Failure Detection (BFD) operations, if the UE operates in a BWP that does not include SSB BandWidth (BW), four options are specified to complete the support of this feature):

[0106] Option A) Perform BM / RLM / BFD based on CSI-RS within active BWP

[0107] Option B-1-1) Perform BM / RLM / BFD based on SSB outside active BWP without interruptions

[0108] Option B-1-2) Perform BM / RLM / BFD based on SSB outside active BWP with interruptions

[0109] Option C) Perform BM / RLM / BFD based on NCD-SSB within active BWP for non-RedCap UEs

[0110] Additionally, for Option B-1-1 and C, it was specified requirements for L3 intra-frequency measurements without gaps. Moreover, for Option C, handover requirements based on existing RedCap handover requirements were specified.

[0111] Description

[0112] Option A

[0113] RAN4 has agreed that existing legacy RRM requirements are applicable for UEs supporting Option A. No specification changes were made for this option apart from capability signalling aspects.

[0114] Option B-1-1

[0115] The SSB-based requirements for BM / RLM / BFD measurements, L3 intra-frequency measurements without measurement gaps, and timing, were updated to capture their applicability for UEs supporting Option B-1-1 if CD-SSB is within the channel bandwidth of the UE. Capability signalling aspects were specified to convey the support of this option.

[0116] Option B-1-2

[0117] RAN4 decided not to define the requirements for option B-1-2 due to lack of consensus on how to define the requirement. No specification changes were made for this option apart from capability signalling aspects.

[0118] Option C

[0119] The SSB-based requirements for BM / RLM / BFD measurements, L3 intra-frequency measurements without measurement gaps, and timing, were updated to capture their applicability for NCD-SSB for UEs supporting Option C.

[0120] Requirements for the transition between CD-SSB and NCD-SSB for BM / RLM / BFD measurements and L3 measurements were introduced for UEs supporting Option C based on the existing requirements from RedCap.

[0121] Handover requirements based on the existing requirements from RedCap were introduced for non-RedCap for the following scenarios:

[0122] Intra frequency handover from NCD-SSB to NCD-SSB

[0123] Inter frequency handover form NCD-SSB to CD-SSB

[0124] Inter frequency handover from CD-SSB to NCD-SSB

[0125] Inter frequency handover from NCD-SSB to NCD-SSB

[0126] Existing RRC configuration signalling for NCD-SSB was reused and the capability signalling aspects were specified to convey the support of this option.

[0127] The energy-saving signal introduced in the relevant technology is mainly to reduce the power consumption of PDCCH detection, while the power consumption of RRM measurement is saved through the RRM measurement relaxation mechanism. The WUS introduced in the relevant technology is to further reduce the power consumption caused by the UE's main receiver being turned on to detect PDCCH. In addition to detecting PDCCH, the UE's main receiver must also be turned on periodically to perform RRM measurements. The time interval for RRM measurements of neighboring cells can be increased through the RRM measurement relaxation mechanism, but the judgment condition for sending RRM measurements is based on the measurement results of the serving cell, and the RRM measurement of the serving cell has not been relaxed. WUS receives the wake-up signal by turning on the WUR receiver, and then triggers the turning on of the main receiver. If the main receiver has to be turned on all the time due to RRM measurement, the power-saving effect brought by the introduced WUS signal will be greatly reduced, and the power-saving gain cannot be reflected.

[0128] Please refer to Figure 8, which shows a flow chart of a measurement method provided by an embodiment of the present application. The method is executed by a terminal device and includes at least one of the following steps 810 to 820.

[0129] Step 810: The terminal device receives a measurement reference signal through the WUR, where the measurement reference signal is used to measure the signal quality of the serving cell.

[0130] Accordingly, the network device sends a measurement reference signal to the terminal device.

[0131] In related technologies, reference signals are often used to measure the signal quality of the serving cell. For example, in LTE systems, network equipment continuously sends CRS (Cell-specific Reference Signal), and terminal devices can measure CRS to determine the cell quality of the serving cell and / or neighboring cells. For example, in 5G NR systems, SSB is introduced to measure cell signal quality.

[0132] In some embodiments, the terminal device can perform RLM measurement, RRM measurement, BFD measurement and other measurements on the measurement reference signal. For example, CRS is used by default for RLM measurement in the LTE system, while CSI-RS is used by default for RLM measurement in the NR system. For example, to support mobility (cell switching, cell reselection, etc.), the network device configures the terminal device with CSI-RS resources of the current serving cell and one or more neighboring cells for RRM measurement, which is also a supplement to SSB-based measurement. For example, similar to RLM, CSI-RS is used to detect whether the transmit beam and the receive beam are misaligned. If they are not aligned, the signal quality will be severely degraded. The difference from RLM is that BFD does not trigger the RRC connection reestablishment process, but uses the beam management process to realign the transmit beam and the receive beam.

[0133] Typically, RLM measurements are performed only on the serving cell, and SPCell: including PCell in SA NR, NR-DC and NE-DC operation mode, PSCell in NR-DC and EN-DC operation mode, and Deactivated PSCell in NR-DC and EN-DC operation mode, when configured (PCell in SA NR, NR-DC and NE-DC operation mode, PSCell in NR-DC and EN-DC operation mode, and deactivated PSCell in NR-DC and EN-DC operation mode (if configured)).

[0134] BFD measurements are performed only on the serving cell: including PCell in SA, NR-DC, or NE-DC operation mode, PSCell in NR-DC and EN-DC operation mode, SCell in SA, NR-DC, NE-DC or EN-DC operation mode, and Deactivated PSCell in NR-DC and EN-DC operation mode.

[0135] In the related technology, in addition to detecting PDCCH, the main receiver of the terminal device must also be turned on periodically to perform RRM measurements. The RRM measurement relaxation mechanism can increase the time interval for performing RRM measurements on neighboring cells. However, the judgment condition for sending RRM measurements is based on the measurement results of the serving cell, and the RRM measurements of the serving cell have not been relaxed. WUS receives the wake-up signal by turning on the WUR receiver, and then triggers the turning on of the main receiver. If the main receiver needs to be turned on periodically due to RRM measurements, the power saving effect brought by the introduced WUS signal will be greatly reduced, and the power saving gain cannot be reflected. Therefore, WUR can be used to share all or part of the service cell measurements for the main receiver, minimize the number of times the main receiver wakes up for measurement, or reduce the interruption required by the main receiver when receiving data.

[0136] In some embodiments, the terminal device receives a measurement reference signal for measuring the signal quality of the serving cell through the WUR.

[0137] In some embodiments, the terminal device may also receive a measurement reference signal for measuring the signal quality of a neighboring cell through the WUR, which is not limited in this application.

[0138] In some embodiments, the measurement reference signal may be any one or more reference signals used to measure the signal quality of a cell. In some implementations, the measurement reference signal may also be other signals exchanged between the cell and the terminal device, which is not limited in this application. For example, the measurement reference signal may be a signal periodically exchanged between the cell and the terminal device.

[0139] In some embodiments, the measurement reference signal includes at least one of the following: SSB, CSI-RS, WUS.

[0140] In some embodiments, the SSB is a combination of a synchronization signal and a PBCH block. It consists of three parts: the Primary Synchronization Signals (PSS), the Secondary Synchronization Signals (SSS), and the PBCH.

[0141] CSI-RS stands for Channel State Information-Reference Signal, a name that's quite self-explanatory. This reference signal is used to obtain channel state information. Unlike CRS, CSI-RS is only valid within the bandwidth allocated to the mobile phone, rather than being transmitted continuously across the entire bandwidth. Therefore, even with support for 8-port transmission, it does not significantly increase system overhead. The network notifies the mobile phone of CSI-RS information through signaling. If no notification is given, the mobile phone assumes that CSI-RS does not exist.

[0142] WUS stands for Wake-Up Signal. This signal is a special PDCCH, scrambled by the RNTI (Radio Network Temporary Identifier) ​​and sent by the network device before the DRX on duration. It indicates whether the terminal device should wake up during the next DRX on duration. In CDRX (Connected Mode DRX), the terminal device periodically wakes up to monitor for scheduled calls. WUS adds another Wake-Up Signal to CDRX, indicating whether the terminal device should wake up during the next period to monitor for scheduled calls. Let's take a simple example: with CDRX alone, the terminal device will wake up periodically, such as at 8:00 a.m. every day without exception. However, with CDRX + WUS, the terminal device does not need to wake up every period. For example, if it receives a text message the night before saying it can sleep in, it does not need to wake up at 8:00 a.m. the next day. This "text message" is the WUS.

[0143] Step 820: The terminal device determines a measurement result based on the measurement reference signal, where the measurement result is used to characterize the signal quality of the serving cell.

[0144] In some embodiments, the measurement result is determined by the WUR based on the measurement reference signal.

[0145] In some embodiments, the measurement result may be RSRP, RSRQ, or other parameters that can characterize the signal quality of the serving cell, which is not limited in this application. For example, the measurement result may also be SINR (Signal to Interference plus Noise Ratio), RSSI (Received Signal Strength Indication), etc.

[0146] In some embodiments, the measurement process performed in steps 810 and 820 above may be a measurement process required during serving cell selection or reselection, or may be used in other processes requiring cell signal quality measurement. For example, it may be used to maintain the mobility of a terminal device and ensure stable signal quality during mobility. For example, it may also be used during initial access of a terminal device.

[0147] The technical solution provided in the embodiment of the present application receives the measurement reference signal through WUR, and there is no need to wake up the main receiver or interrupt the data reception and measurement of the main receiver every time the signal quality measurement of the service cell is performed, thereby reducing the impact on the data reception or measurement of the main receiver and reducing the power consumption of the terminal device.

[0148] Since the status of the main receiver of the terminal device is different when it is in the RRC connected state, RRC idle state and RRC inactive state, for example, in the RRC idle state and RRC inactive state, the main receiver is in a dormant state. At this time, if the main receiver measures the signal quality of the service cell, the WUR needs to wake up the main receiver after receiving the WUS, and then the main receiver performs the measurement. In the RRC connected state, the main receiver is not dormant, so there is no need for the WUR to wake up the main receiver. However, the main receiver may be receiving data at this time. If the main receiver is needed to perform the measurement, the terminal main receiver needs to receive data, or a preset measurement gap is required. Therefore, the embodiment of the present application designs a method for diverting the measurement "pressure" of the main receiver through the WUR for the terminal device in the RRC connected state, the terminal device in the RRC idle state or the RRC inactive state.

[0149] When a terminal device in idle state needs to initiate a service (voice or data), it first initiates an RRC establishment request, triggering the transition from idle to connected state. This process is called the RRC establishment process. If a user in connected state does not transmit data for a period of time, it will enter the inactive state. If an inactive user needs to initiate data transmission, it will transition back to the connected state through the RRC recovery process. If an inactive user continues to have no data transmission for a period of time, it will enter the idle state.

[0150] 1. The terminal device is in RRC idle state, or the terminal device is in RRC inactive state

[0151] In this case, two scenarios are possible. One is to divert some or all of the measurement reference signals that the MR originally needs to receive to the WUR for reception. The other is to disable the MR and no longer receive measurement reference signals. Instead, one or more signals that the WUR can receive are selected as measurement reference signals to complete the measurement of the serving cell.

[0152] In some embodiments, when the terminal device is in an RRC idle state or an inactive state, the method further includes the following step 830.

[0153] Step 830: The terminal device receives first configuration information sent by the network device, where the first configuration information is used to instruct the terminal device to receive a measurement reference signal through the WUR.

[0154] Correspondingly, the network device sends the first configuration information to the terminal device.

[0155] In some embodiments, the first configuration information is RRC dedicated signaling; or, the first configuration information is SIB (System Information Block) configuration information.

[0156] RRC is the control signaling in wireless networks, used to manage and allocate radio resources. When the size of an RRC message exceeds the physical layer bearer capacity, a split bearer is used for transmission. Using a split bearer, a large RRC message can be broken down into smaller segments, which are then transmitted across different bearers.

[0157] There are many types of SIBs, and SIBs specifically include SIB1 and SIB2 to 13. The early SIB1 was also called SU-1 (Scheduling Unit-1), and other SIBs were called SU-n. Different SIBs carry different parameters and have different purposes. For example, SIB1 mainly carries information related to cell access and cell selection, as well as LTE-TDD (Time-Division Duplex) subframe configuration, scheduling and window information of other SIBs, etc. The most important of all SIBs is SIB1, because in addition to carrying the parameters required for terminal devices to access the cell, SIB1 also carries scheduling information of other SIB types. If the terminal device cannot decode SIB1, it will not be able to decode other types of SIBs.

[0158] In some embodiments, the first configuration information is used to explicitly instruct the terminal device how to receive the measurement reference signal via the WUR. For example, the first configuration information may be used to instruct the terminal device whether to receive all or part of the measurement reference signal via the WUR.

[0159] In some embodiments, the first configuration information is used to indicate that when the MR (Main Radio) is turned off, the WUR is used to receive all measurement reference signals. For example, the first configuration information is used to indicate that when the MR is turned off (or MR is dormant), the WUR does not need to wake up the MR, but can receive all measurement reference signals, thereby reducing power consumption caused by frequently waking up the MR.

[0160] In some embodiments, the first configuration information is used to indicate that when the MR is turned off, the WUR is used to receive part of the measurement reference signal. In some embodiments, the first configuration information is used to indicate that when the MR is turned off, the WUR is used to receive part of the measurement reference signal.

[0161] In some embodiments, when the first configuration information is used to indicate that the WUR is used to receive part of the measurement reference signal when the MR is turned off, the first configuration information is also used to indicate the measurement reference signal that the WUR is used to receive. Exemplarily, the first configuration information can be used to indicate the time-frequency resources where the measurement reference signal that the WUR needs to receive is located. In some embodiments, the first configuration information is used to indicate that the WUR is used to receive the measurement reference signal on the first carrier, and the first carrier includes at least one of the following: the carrier where the service cell is selected, and the EMR carrier. In some embodiments, the terminal device can obtain the EMR configuration in the RRC release message or SIB.

[0162] In some embodiments, the WUR may perform the measurement process for the signal quality of the serving cell only within a period of time. In some embodiments, the time that the WUR needs to perform the measurement process is configured by the network device. In some embodiments, the WUR starts to perform the measurement process after receiving the first configuration information. In some embodiments, the end time of the WUR performing the measurement process is maintained by a timer, and the timer is configured by the network device. In some embodiments, the timer is independent of the main receiver. In some embodiments, the timer may also be preconfigured or predefined. In some embodiments, the timer is a newly defined timer, or an existing timer may be reused. Exemplarily, the timer may be T331. Exemplarily, the duration of the timer may be configured by the first configuration information.

[0163] In some embodiments, WUS may be used as or in place of an existing measurement reference signal for a serving cell in an RRC idle or inactive state. The terminal device receives WUS via WUR to complete the measurement of the serving cell, while MR is turned off and no longer measures. Of course, other signals that can be received by WUR may also be used as measurement reference signals to achieve the above functions, and this application is not limited to this.

[0164] In some embodiments, the measurement reference signal is a wake-up signal WUS; the above step 810 can be implemented as the following step 811 .

[0165] Step 811: The terminal device receives WUS via WUR. WUS is a periodically transmitted signal with a synchronization signal function.

[0166] In some embodiments, the method further includes the following step 840 .

[0167] Step 840: The terminal device receives second configuration information sent by the network device, where the second configuration information is used to configure at least one of the following: a cell selection judgment threshold corresponding to the WUS, an S criterion corresponding to the WUS, and a signal-to-noise ratio (SNR) condition corresponding to the WUS.

[0168] In some embodiments, the second configuration information is further used to indicate that the sounding reference signal is WUS.

[0169] In some embodiments, since WUS differs from SSB or CSI-RS in transmission parameters, the measurement results obtained by the terminal device after measuring WUS will also be different. The cell selection judgment threshold, S criterion, SNR (Signal-to-Noise Ratio) conditions, etc. set for SSB or CSI-RS are not applicable to WUS, so the relevant threshold values ​​and / or condition parameters are reset for WUS.

[0170] In some embodiments, the DRX corresponding to WUR is different from the DRX corresponding to MR.

[0171] In wireless networks, when data needs to be transmitted, terminal devices must constantly monitor the PDCCH and send and receive data based on instructions sent by network devices. This results in high power consumption and data transmission latency. Therefore, DRX energy-saving strategies have been introduced. DRX operating states are categorized into Idle-DRX and Connected-DRX.

[0172] In Idle-DRX mode, the terminal device has no wireless resource connection and mainly monitors the call channel and broadcast channel. In order to achieve discontinuous reception, it is only necessary to configure a fixed sleep cycle. The DRX cycle in idle mode is divided into an active period and a sleep period. In Connected-DRX mode, the UE has three states, namely, an active period, a short DRX cycle (shallow sleep period) and a long DRX cycle (deep sleep period). During the active period, the terminal device can turn on the receiver to detect PDCCH. During the sleep period, the transceiver unit is turned off and the PDCCH is not monitored. The light sleep period and deep sleep period are distinguished according to the different sleep cycles.

[0173] Therefore, the DRX of the WUR and the primary receiver can be different to achieve wider coverage of the PDCCH.

[0174] In some embodiments, the DRX cycle corresponding to WUR is different from the DRX cycle corresponding to MR. Exemplarily, the DRX cycle corresponding to WUR is greater than the DRX cycle corresponding to MR.

[0175] In some embodiments, the length of the DRX corresponding to the WUR is different from the length of the DRX corresponding to the MR. For example, the length of the DRX corresponding to the WUR is greater than the length of the DRX corresponding to the MR. Since the WUR is more power-efficient, the WUR can be used to monitor the PDCCH for a longer period of time.

[0176] In some embodiments, the WUR is further configured to receive at least one of the following: paging and SIB. In some embodiments, if a conflict occurs between the WUR and the measurement of the serving cell while processing the aforementioned services, the WUR may handle the conflict using the same method as the primary receiver, such as by adding an interrupt during the processing of the aforementioned services to receive a measurement reference signal.

[0177] Through the above method, when the terminal device is in the RRC idle state or the RRC inactive state, the measurement reference signal that the MR needs to receive can be diverted through the WUR, without waking up the main receiver every time the signal quality measurement of the service cell is performed, thereby reducing the power consumption of the terminal device.

[0178] 2. The terminal device is in RRC connected state

[0179] In some embodiments, when the terminal device is in an RRC connected state, the primary receiver is in an operating state and can receive a measurement reference signal to measure the serving cell. However, when receiving the measurement reference signal, the primary receiver may need to receive data or perform other measurement processes. In this case, it is necessary to set an interrupt during the process of the primary receiver receiving data, or set a measurement gap for the primary receiver. Therefore, WUR can be used to receive the measurement reference signal, perform offload, and reduce the processing pressure of the primary receiver.

[0180] In some embodiments, the WUR and the main receiver may divide the measurement processes that need to be performed into two categories, wherein the WUR performs the first category of measurement processes and the main receiver performs the second category of measurement processes.

[0181] In some embodiments, the terminal device is in an RRC connected state, the WUR is used to perform a first type of measurement process, and the main receiver MR is used to perform a second type of measurement process.

[0182] In some embodiments, the first type of measurement process and the second type of measurement process may be divided based on the measurement object. For example, the measurement process for the primary cell is divided into the second type of measurement process, and the measurement process for the primary and secondary cells is divided into the first type of measurement process.

[0183] In some embodiments, the first type of measurement process and the second type of measurement process may be divided based on the priority of the cells to be measured. For example, the measurement process for a cell with a high priority is divided into the second type of measurement process, and the measurement process for a cell with a low priority is divided into the first type of measurement process.

[0184] In some embodiments, the first and second measurement procedures may be divided based on the signal quality requirements of the cells to be measured. For example, the measurement procedure for cells with higher signal quality requirements is divided into the second measurement procedure, and the measurement procedure for cells with lower signal quality requirements is divided into the first measurement procedure.

[0185] In some embodiments, the first type of measurement process and the second type of measurement process can be divided based on the antenna panel where the cell to be measured is located. For example, for FR2, the antenna panel in FR2 is currently bound to the RF link. Due to the physical structure of the FR2 antenna panel, it is impossible to allocate independent link resources to the WUR for measuring the primary cell and / or primary and secondary cells in FR2.

[0186] In some embodiments, the first type of measurement process includes at least one of the following: a measurement process for a primary and secondary cell in NR in EN-DC (E-UTRA NR Dual-C onnectivity, E-UTRA (Evolved Universal Terrestrial Radio Access, Evolved Universal Radio Access) and NR dual connectivity) mode;

[0187] Measurement process for primary and secondary cells in LTE in NE-DC (NR and E-UTRA dual connectivity) mode;

[0188] In NR-DC (NR and NR dual connectivity) mode, the measurement process for the primary cell and / or primary and secondary cells in FR1;

[0189] In NR CA (NR carrier aggregation) mode, the measurement process for the primary cell and / or primary and secondary cells in FR1;

[0190] BFD measurement for the secondary cell.

[0191] In some embodiments, the second type of measurement procedure includes at least one of the following: a measurement procedure for a primary and secondary cell in LTE in EN-DC mode;

[0192] In NE-DC mode, the measurement process for the primary and secondary cells in NR;

[0193] In NR-DC mode, the measurement process for the primary cell and / or primary and secondary cells in FR2;

[0194] In NR CA mode, the measurement process for the primary cell and / or primary and secondary cells in FR2;

[0195] BFD measurement for the primary cell and / or primary and secondary cells.

[0196] For example, in EN-DC, 4G is the primary node and 5G is the secondary node, so the measurement process for the primary and secondary cells in LTE can be classified as the second type of measurement process. In NE-DC, 5G is the primary node and 4G is the secondary node, so the measurement process for the primary and secondary cells in NR can be classified as the second type of measurement process.

[0197] For example, for FR2, the antenna panel and RF link are currently bound together. Due to the physical structure of the FR2 antenna panel, it is not possible to allocate independent link resources to the WUR for measuring the primary cell and / or primary and secondary cells in FR2. Of course, if FR2 changes in the future, it is also possible to consider using the WUR to perform measurements on the primary cell and / or primary and secondary cells in FR2.

[0198] In some embodiments, BFD differs from RLM in that, in addition to measurements on PCells and PScells, BFD measurements may also be configured on Scells. For example, BFD measurements on secondary cells may be prioritized over WUR measurements, with the more important primary cells and / or primary and secondary cells receiving a lower priority.

[0199] In some embodiments, the first type of measurement process and the second type of measurement process may be divided according to the measurement reference signal. For example, the first type of measurement process and the second type of measurement process may be divided according to whether the measurement reference signal to be measured is an SSB or a CSI-RS.

[0200] In some embodiments, the measurement reference signal corresponding to the first type of measurement process is SSB, and the measurement reference signal corresponding to the second type of measurement process is CSI-RS.

[0201] In some embodiments, the measurement reference signal corresponding to the first type of measurement process is a CSI-RS, and the measurement reference signal corresponding to the second type of measurement process is an SSB.

[0202] In some embodiments, the BLE of the RLM measurement and the measurement timing are determined by mixing the SSB or CSI-RS as the RLM-RS. Dividing the traffic by the measurement reference signal has the advantage of saving power but the disadvantage of extending the RLM time.

[0203] In some embodiments, the first and second measurement processes can be separated based on the measurement scenario. In some embodiments, the first and second measurement processes can be separated based on whether a measurement gap or an interruption occurs. For example, measurement processes that generate a measurement gap are classified as the first category, while those that do not generate a measurement gap are classified as the second category.

[0204] In related technologies, serving cell RLM and BFD measurements are all performed outside the gap, which requires certain configurations or UE capabilities. In some embodiments, the above step 810 can be implemented as the following step 812.

[0205] Step 812: When the first condition is met, the terminal device receives a measurement reference signal through the WUR.

[0206] In some embodiments, the first condition includes at least one of the following:

[0207] CD-SSB is within the BWP;

[0208] The terminal device supports the measurement process based on NCD-SSB, and NCD-SSB is within the BWP;

[0209] The terminal device supports the measurement process based on CSI-RS, and the CSI-RS is within the BWP;

[0210] The terminal device supports the measurement process based on CD-SSB and / or CSI-RS being outside the BWP without interruption;

[0211] The terminal device supports the measurement process based on CD-SSB and / or CSI-RS being outside the BWP and requiring interruption;

[0212] The terminal device supports the measurement process where the measurement reference signal is outside the BWP and measurement gaps are required;

[0213] Among them, BWP is the BWP activated on the serving cell.

[0214] The first condition mentioned above can be divided into three parts. The first is whether the terminal device supports the ability to perform measurement based on the measurement reference signal, the second is whether the measurement reference signal is within the BWP, and the last is whether the measurement process will interrupt the MR or whether the MR needs a gap to handle the measurement process.

[0215] If the terminal device supports the capability to perform measurements based on a measurement reference signal, and the measurement reference signal is within the BWP, the measurement process can be performed using either the WUR or the MR. If the terminal device supports the capability to perform measurements based on a measurement reference signal, and the measurement reference signal is outside the BWP, the measurement process can be divided based on whether an interruption will occur or whether a gap is required. If an interruption will occur or a gap is required, the measurement process can be performed using the WUR; if no interruption will occur or a gap is required, the measurement process can be performed using the MR.

[0216] Based on the above situations, MR and WUR can determine which measurements to measure in MR or WUR according to the current network configuration of UE BWP, CD-SSB or NCD-SSB in the service cell MO or dedicated BWP, and the UE's ability to support the above scenarios.

[0217] Taking the first condition that the terminal device supports the measurement reference signal outside the BWP and the measurement process that requires a measurement gap as an example, for terminal devices that support the ability to measure the reference signal outside the BWP and the RLM-RS of the serving cell (such as CD-SSB or NCD-SSB) are not within the activated BWP, the terminal device uses WUR to offload the measurement of part or all RLM-RS, especially those that require a gap to complete the measurement. The advantage is that there is no need for MR to use an additional gap to complete the serving cell measurement, the measurement or data scheduling of MR and WUR can overlap in the time domain, and there is no need for periodic per-UE or per-FR gap interruptions. At this time, the measurement bandwidth of WUR must at least be able to cover the RLM-RS to be measured, and it is also potentially required that its working bandwidth and the working bandwidth of the MR receiver be staggered in the frequency domain. For example, the channel bandwidth of the terminal device is shown in Figure 9, which includes a bandwidth 910 for data transmission and a bandwidth 920 for WUS transmission. WUR operates on the bandwidth 920 for WUS transmission, and MR operates on the bandwidth 910 for data transmission.

[0218] Through the above method, WUR receives the measurement reference signal, and there is no need to wake up the main receiver every time the signal quality measurement of the service cell is performed, interrupting the data reception and measurement of the main receiver, reducing the impact on the data reception or measurement of the main receiver, and at the same time reducing the power consumption of the terminal device.

[0219] In the above method embodiments, the technical solution of this application is described only from the perspective of the interaction between a terminal device and a network device. The above steps performed by the terminal device can be independently implemented as a measurement method on the terminal device side, and the above steps performed by the network device can be independently implemented as a measurement method on the network device side. In addition, the embodiments provided herein can be arbitrarily combined to form new embodiments, which are all within the scope of protection of this application.

[0220] The following are device embodiments of the present application, which can be used to implement the method embodiments of the present application.

As shown in Figure 10, the device 1000 may include: a receiving module 1010 and a processing module 1020.

[0222] The receiving module 1010 is used to receive a measurement reference signal through the WUR, where the measurement reference signal is used to measure the signal quality of the serving cell.

[0223] The processing module 1020 is configured to determine a measurement result based on the measurement reference signal, where the measurement result is used to characterize the signal quality of the serving cell.

[0224] In some embodiments, when the terminal device is in a radio resource control RRC idle state or an inactive state,

[0225] The receiving module 1010 is further used to receive first configuration information sent by a network device, where the first configuration information is used to instruct the terminal device to receive the measurement reference signal through the WUR.

[0226] In some embodiments, the first configuration information is RRC dedicated signaling; or, the first configuration information is SIB configuration information.

[0227] In some embodiments, the first configuration information is used to indicate that when the MR is turned off, the WUR is used to receive all the measurement reference signals; or

[0228] The first configuration information is used to instruct the WUR to receive the measurement reference signal on a first carrier, where the first carrier includes at least one of the following: a carrier where the serving cell is selected, and an EMR carrier.

[0229] In some embodiments, the end time of the WUR execution measurement process is maintained by a timer, and the timer is configured by the network device.

[0230] In some embodiments, the measurement reference signal is WUS;

[0231] The receiving module 1010 is used to receive the WUS through the WUR. The WUS is a periodically transmitted signal with a synchronization signal function.
