Description

Technical Field

[0001] This application relates to the field of communications, and more particularly to a cell assessment method and apparatus. Background Technology

[0002] In wireless communication systems, the low-power wake-up radio (LP-WUR) mechanism can achieve lower power consumption in terminal devices. Its principle is as follows: The terminal device has a main receiver (MR) and a low-power wake-up receiver (LP-WUR or LR). The LP is used to monitor the low-power wake-up signal (LP-WUS) sent by the network side, while the MR is used for normal data / service transmission. When there is no ongoing data / service transmission on the MR, it can enter a shutdown or sleep state to significantly reduce the power consumption of the terminal device when in "standby." Simultaneously, the LR is turned on to monitor the LP-WUS. When the LR receives the LP-WUS, it wakes up the MR to perform data / service transmission. The LP-WUR mechanism allows the main receiver of the terminal device to be switched off when not in use, thus improving the energy efficiency of the terminal device.

[0003] To achieve energy saving in idle / inactive states, when the serving cell is in a normal state, the terminal device measures and evaluates the serving cell in units of discontinuous reception (DRX) cycles. However, the DRX cycle is relatively long; for example, the candidate values ​​for the DRX cycle specified in the protocol are {0.32s, 0.64s, 1.28s, 2.56s}. When the MR wakes up, evaluating the serving cell in DRX cycles poses a risk of delayed cell reselection due to untimely measurement and evaluation, which in turn may cause the terminal device to miss paging messages, affecting the user's communication experience. Summary of the Invention

[0004] This application provides a cell assessment method and apparatus that can avoid the problem of missed paging due to untimely cell reselection, and can balance the timeliness and accuracy of cell assessment with energy saving of terminal equipment, thereby improving the user's communication experience.

[0005] Firstly, a cell evaluation method is provided, which can be applied to a terminal device, or a chip or module in the terminal device. Taking application to a terminal device as an example, the method includes: determining the exit conditions that meet a first state; after a first duration, within a second duration, evaluating the S criterion of the serving cell based on a first period using MR, where the first period is a positive integer multiple of the period of the serving cell's physical broadcast channel block (synchronization signal and PBCH block, SSB).

[0006] In this embodiment, after exiting the first state, the terminal device evaluates the serving cell's S-criteria based on the first cycle using MR (Mean Detection). This allows for a rapid determination of whether the current serving cell is suitable for camping (i.e., a rapid determination of whether cell reselection is needed) after MR wake-up, avoiding the problem of missed paging due to untimely serving cell measurement and evaluation. Furthermore, this scheme limits the evaluation of the serving cell's S-criteria based on the first cycle to the second duration, avoiding the power consumption waste caused by prolonged evaluation based on the first cycle. Additionally, compared to evaluating the serving cell's S-criteria using LR (Low-Low-Low) methods, evaluating the serving cell's S-criteria using MR methods avoids the impact of adjacent channel interference on the evaluation results, ensuring the accuracy of the evaluation results. In summary, this embodiment can balance the timeliness and accuracy of cell evaluation with energy-saving effects on the terminal device.

[0007] In one possible design, the first state includes at least one of the following: LP-WUS monitoring; complete offloading of radio resource management (RRM) measurements; and RRM measurement relaxation.

[0008] This design clarifies which states the first state can be, thus improving the reliability of the solution.

[0009] In one possible design, the first cycle is shorter than the discontinuous reception DRX cycle.

[0010] This design can accelerate the evaluation of the serving cell based on the S criterion in the first cycle through MR, which helps the terminal equipment to measure and evaluate the serving cell in a timely manner.

[0011] In one possible design, if the serving cell is in a continuous N serv If none of the SSB cycles satisfy the S criterion, then regardless of the current measurement rules restricting the terminal device's measurement activities, measurements of all neighboring cells indicated by the serving cell will be initiated; where N serv It is a positive integer, and the second duration is equal to N consecutive integers. serv The duration of each SSB cycle.

[0012] In this design, the second duration is determined by the number of measurements N serv which features a simple implementation; at the same time, it can minimize the duration of measurement and evaluation of the serving cell based on the first period, saving power consumption of the terminal device.

[0013] In a possible design, N serv is related to the SSB period. For example, the larger the SSB period, the N serv is smaller or remains unchanged.

[0014] In this way, it can be ensured that the value of the second duration is within a reasonable range under different SSB periods.

[0015] In a possible design, if N out of N consecutive SSB periods of the serving cell do not satisfy the S criterion, regardless of the current measurement rule restricting the measurement activity of the terminal device, the terminal device starts measurements on all neighboring cells indicated by the serving cell; where N serv = T / SSB period, and T is the second duration. serv =T / SSB周期,T为第二时长。

[0016] This design can improve the flexibility of cell evaluation. For example, when it is desired that the terminal device has a longer time to measure and evaluate the quality of the serving cell, T can be set to a larger value; when it is desired that the terminal device is more power-saving, T can be set to a smaller value.

[0017] In a possible design, T and N are configured by the network.

[0018] In this design, the second duration can be configured through the network, and the network has more flexible management of measurement tasks. For example, when the network expects the terminal device to have a longer time to measure and evaluate the quality of the serving cell, T can be configured to a larger value; when the network expects the terminal device to be more power-saving, T can be configured to a smaller value.

[0019] In a possible design, when the first condition is met, the S criterion of the serving cell is evaluated by the MR based on the first period; where the first condition includes at least one of the following:

[0020] The first state includes that RRM measurement is completely offloaded and the network does not configure RRM measurement relaxation; or, the first state includes RRM measurement relaxation;

[0021] The threshold in the MR threshold - S criterion in the entry condition of the first state is less than X, where X≥0;

[0022] Before the exit condition of the first state is satisfied, the measurement result of LR is less than the first LR threshold.

[0023] If the above conditions are met, it indicates that the terminal device is far from the serving base station, or the terminal device is located at the edge of the serving cell, and the possibility of cell reselection is high, requiring high timeliness of serving cell measurement and evaluation.

[0024] Based on the above design, the serving cell can be evaluated in the first cycle as soon as possible when cell reselection is required, thus enabling rapid evaluation of the serving cell and avoiding the terminal device from missing paging.

[0025] In one possible design, if the first condition is not met and / or the second condition is met, measurements are performed on the serving cell and neighboring cells based on the DRX cycle.

[0026] If the above conditions are met, it indicates that the terminal device is not far from the serving base station, or that the terminal device is likely located in the center of the serving cell, the possibility of cell reselection is low, and the timeliness requirement for serving cell measurement and evaluation is low.

[0027] Based on the above design, it is possible to avoid rapid evaluation of the serving cell when cell reselection is not required, thereby saving energy consumption of terminal equipment.

[0028] In one possible design, the second condition includes: the first state includes LP-WUS monitoring and exiting the first state is triggered by the terminal device receiving LP-WUS; or, the first state includes complete RRM measurement offloading and does not meet the exit condition of network not being configured to relax RRM measurement.

[0029] The above design clarifies what the second condition can be, thus improving the reliability of the solution.

[0030] Secondly, a cell evaluation method is provided, which can be applied to a terminal device, or a chip or module in the terminal device. Taking application to a terminal device as an example, the method includes: receiving first configuration information, second configuration information, and third configuration information, wherein the first configuration information is used to configure first measurement resources, the second configuration information is used to configure second measurement resources, and the third configuration information is used to configure third measurement resources; the first measurement resources are used for measuring and evaluating the serving cell based on LR, the second measurement resources are used for measuring and evaluating the serving cell based on MR, and the third measurement resources are used for searching, measuring, and evaluating neighboring cells based on MR; and according to the first configuration information, the second configuration information, and the third configuration information, performing measurement and evaluation of the serving cell based on LR in a second period, performing measurement and evaluation of the serving cell based on MR in a third period, and performing searching, measuring, and evaluating neighboring cells based on MR in a fourth period.

[0031] This application provides a scheme for simultaneous measurement of LR and MR, avoiding the need for terminal devices to use MR and LR for measurement at the same reference signal measurement time, ensuring the flexibility of terminal device implementation, and improving the communication performance of terminal device.

[0032] In one possible design, the second period is N1*T detect T detect It is the period based on MR search and evaluation of whether new detectable co-frequency or inter-frequency cells meet the reselection conditions, where N1 is a positive integer.

[0033] In this design, N1*T detect Within this framework, the measurement and evaluation of the serving cell based on MR, as well as the search, measurement, and evaluation of neighboring cells based on MR, do not occupy all available measurement opportunities. Therefore, there are opportunities available for the measurement and evaluation of the serving cell based on LR, which helps to achieve simultaneous MR and LR measurements and minimize the impact of LR measurements on MR measurements.

[0034] In one possible design, N1 is related to the discontinuous reception DRX period.

[0035] For example, the larger the DRX period, the smaller N1 becomes or it remains unchanged.

[0036] In this way, it can be ensured that the value of the second cycle is within a reasonable range under different DRX cycles.

[0037] In one possible design, neighboring cells include co-frequency neighboring cells and inter-frequency neighboring cells; the fourth cycle includes a fifth cycle corresponding to co-frequency neighboring cells and a sixth cycle corresponding to inter-frequency neighboring cells; if the first measurement resource is an SSB, then the second cycle is N2. SSB *L*DRX period; if the first measurement resource is a low-power synchronization signal (LP-SS), then the second period is N2. LP-SS *L*LP-SS period; where L=m+n, N2 SSB and N2 LP-SS L represents the number of samples required to evaluate the serving cell based on LR, where L is a positive integer and N² is the number of samples required. SSB and N2 LP-SS Let m be a positive integer and n be a positive integer.

[0038] The sixth period is determined based on m+n;

[0039] Where m is the number of inter-frequency points configured by the network for searching, measuring, and evaluating neighboring cells based on MR.

[0040] In this design, based on the number m of inter-frequency points configured for MR-based search, measurement, and evaluation of neighboring cells, n inter-frequency points are added. This increases the period for MR-based search, measurement, and evaluation of inter-frequency neighboring cells. Consequently, within the MR-based search, measurement, and evaluation period for inter-frequency neighboring cells, there are opportunities available for LR-based measurement and evaluation of the serving cell. This helps to achieve simultaneous MR and LR measurements, avoids increasing the latency of MR measurement and evaluation of the serving cell, and minimizes the impact of LR measurement on MR measurement.

[0041] In one possible design, neighboring cells include co-frequency neighboring cells and inter-frequency neighboring cells; the fourth cycle includes a fifth cycle corresponding to co-frequency neighboring cells and a sixth cycle corresponding to inter-frequency neighboring cells.

[0042] If the first measurement resource is SSB, then the second cycle is N2. SSB *N3*DRX cycle; if the first measurement resource is LP-SS, then the second cycle is N2. LP-SS *N3*LP-SS cycle; where N2 SSB and N2 LP-SS To determine the number of sample points required for evaluating the serving cell based on LR, N2 SSB and N2 LP-SS N is a positive integer, and N3 is a positive integer;

[0043] The third cycle is N4*N5*DRX cycle; where N4 is the number of sample points required for MR measurement and evaluation of the serving cell, N4 is a positive integer, and N5 is a positive integer;

[0044] The fifth cycle is N6*N7*DRX cycle; where N6 is the number of sample points required for MR search, measurement and evaluation of neighboring cells, N6 is a positive integer, and N7 is a positive integer;

[0045] The sixth cycle is N8*N9*DRX cycle; where N8 is the number of sample points required for MR search, measurement and evaluation of neighboring cells, N8 is a positive integer, and N9 is a positive integer;

[0046] Among them, at least one of N5, N7, and N9 is greater than 1.

[0047] In this design, the search, measurement and evaluation of inter-frequency neighboring cells based on MR, the search, measurement and evaluation of co-frequency neighboring cells based on MR, and the measurement and evaluation of the serving cell based on MR, at least one of the above three items has an increased delay (i.e., at least one of N5, N7, and N9 is greater than 1). This can ensure that within the increased period, there is an opportunity to use the measurement and evaluation of the serving cell based on LR, thus enabling simultaneous MR and LR measurements.

[0048] In one possible design, when at least one of the following conditions is met, based on the first configuration information, the second configuration information, and the third configuration information, the following actions are performed: LR-based measurement and evaluation of the serving cell in the second period; MR-based measurement and evaluation of the serving cell in the third period; and MR-based search, measurement, and evaluation of neighboring cells in the fourth period:

[0049] The third condition includes: the measurement results of MR to the serving cell meet the MR threshold in the entry condition of the first state, wherein the first state includes at least one of low power wake-up signal LP-WUS monitoring, complete offloading of radio resource management (RRM) measurement, or RRM measurement relaxation.

[0050] The fourth condition includes: the first measurement resource includes LP-SS, the same-frequency SSB-based measurement timing configuration (SMTC) and the different-frequency SMTC have time conflicts, and SMTC and LP-SS have time conflicts;

[0051] The fifth condition includes: the first measurement resource includes SSB, and there is a time conflict between the same-frequency SMTC and the different-frequency SMTC.

[0052] Optionally, the fourth condition also includes: DRX period = 2T, same-frequency SMTC period = different-frequency SMTC period = T, LP-SS period = 2T; T is a positive integer.

[0053] Optionally, the fifth condition also includes: DRX period = 2T, same-frequency SMTC period = different-frequency SMTC period = T, SSB period = T; T is a positive integer.

[0054] By adopting the above design method, LR measurement and MR measurement can be performed only when necessary (such as when the MR measurement result meets the MR threshold in the entry condition of the first state) or when there is a conflict between LR measurement and MR measurement. This avoids the reduction in measurement performance caused by using the above periodic configuration method when LR measurement is not necessary or when there is no conflict between LR measurement and MR measurement timing.

[0055] In one possible design, the first measurement resources include LP-SS and SSB;

[0056] When the fourth condition is met, based on the first configuration information, the second configuration information, and the third configuration information, a measurement and evaluation of the serving cell based on LR is performed within the second period, including: based on the first configuration information, the second configuration information, and the third configuration information, a measurement and evaluation of the serving cell based on SSB is performed within the second period; or,

[0057] When the fifth condition is met, the measurement and evaluation of the serving cell based on LR is performed in the second period according to the first configuration information, the second configuration information and the third configuration information, including: the measurement and evaluation of the serving cell based on LR based on LP-SS is performed in the second period according to the first configuration information, the second configuration information and the third configuration information.

[0058] The fourth condition includes: the first measurement resource includes LP-SS, the same-frequency SMTC and the different-frequency SMTC have time conflicts, and the SMTC and LP-SS have time conflicts.

[0059] The fifth condition includes: the first measurement resource includes SSB, and there is a time conflict between the same-frequency SMTC and the different-frequency SMTC.

[0060] Optionally, the fourth condition also includes: DRX period = 2T, same-frequency SMTC period = different-frequency SMTC period = T, LP-SS period = 2T; T is a positive integer.

[0061] Optionally, the fifth condition also includes: DRX period = 2T, same-frequency SMTC period = different-frequency SMTC period = T, SSB period = T; T is a positive integer.

[0062] In this design, if measuring SSB by LR causes a timing conflict between LR and MR measurements, then LR measures LP-SS; if measuring LP-SS by LR causes a timing conflict between LR and MR measurements, then LR measures SSB. Selecting a reference signal that does not conflict with MR measurements for LR measurement avoids performance degradation.

[0064] For example, a communication device may include:

[0065] The processing module is used to determine the exit conditions that meet the first state; after the first time period, it is determined that within the second time period, the S criterion of the serving cell is evaluated by MR based on the first cycle.

[0066] The transceiver module is used to receive the radio signal of the serving cell to support the processing module in evaluating the S criterion of the serving cell based on the first cycle through MR.

[0094] In this application embodiment, the number of nouns, unless otherwise specified, refers to "singular nouns or plural nouns," that is, "one or more." "At least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. For example, A / B means: A or B. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b and / or c means: a exists alone, b exists alone, c exists alone, a and b exist simultaneously, b and c exist simultaneously, a and c exist simultaneously, or a, b and c exist simultaneously, where a, b, and c can be single or multiple.

[0095] In this application, the ordinal numbers such as "first" and "second" mentioned are used to distinguish multiple objects, and are not used to limit the size, content, order, timing, priority, or importance of the multiple objects. For example, the first cycle and the second cycle can be the same cycle or different cycles, and such names do not indicate that the two cycles are different in duration, application scenario, priority, or importance.

[0096] The following describes the application scenarios of this application.

[0097] The technical solutions provided in this application can be applied to various communication systems, such as long-term evolution (LTE) systems, fifth-generation (5G) systems, new radio (NR) systems, or future mobile communication systems or other similar communication systems, etc., without any specific limitations.

[0098] Figure 1 An exemplary schematic diagram of the architecture of a communication system 1000 to which this application embodiment applies is shown. For example... Figure 1 As shown, the communication system includes a wireless access network 100 and a core network 200. Optionally, the communication system 1000 may also include an Internet 300. The wireless access network 100 may include at least one wireless access network device (such as...). Figure 1 110a and 110b in the above), may also include at least one terminal device (such as Figure 1(Referring to 120a-120j in the original text). Terminal devices connect wirelessly to wireless access network (WLAN) devices, which in turn connect wirelessly or via wired connections to the core network. The core network devices and WLAN devices can be independent physical devices, or they can integrate the functions of the core network devices and the logical functions of the WLAN devices onto a single physical device. Alternatively, a single physical device can integrate some core network device functions and some WLAN device functions. Terminal devices and WLAN devices can be interconnected via wired or wireless connections. Figure 1 This is just an illustration; the communication system may also include other network devices, such as wireless repeaters and wireless backhaul devices. Figure 1 It is not shown in the middle.

[0099] The network devices involved in the embodiments of this application include, for example, radio access network (RAN) devices. RAN devices can be base stations, evolved NodeBs (eNodeBs), transmission reception points (TRPs), transmission points (TPs), base stations in 5th generation (5G) mobile communication systems, base stations in future mobile communication systems, or access nodes in WiFi systems; they can also be modules or units that perform some of the functions of a base station, for example, they can be central units (CUs), distributed units (DUs), or radio units (RUs). The CU (Radio Control Unit) performs the functions of the radio resource control protocol and packet data convergence protocol (PDCP) of the base station, and can also perform the functions of the service data adaptation protocol (SDAP). The DU (Radio Link Control Unit) performs the functions of the radio link control layer and medium access control (MAC) layer of the base station, and can also perform some or all of the physical layer functions. For specific descriptions of the above protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP). The CU and DU can be set up separately, or they can be included in the same network element, such as in the baseband unit (BBU). The RU (Radio Receiver Unit) can be included in radio frequency equipment or radio frequency units, such as in the remote radio unit (RRU), active antenna unit (AAU), or remote radio head (RRH).

[0100] In different systems, CU, DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an open radio access network (O-RAN) system, CU can also be called open CU (open-CU, O-CU), DU can also be called open DU (open-DU, O-DU), and RU can also be called open RU (open-RU, O-RU). In this application, any of the following units—CU (or CU control plane (CU-CP), CU user plane (CU-UP), DU, and RU)—can be implemented through software modules, hardware modules, or a combination of software and hardware modules. CU-CP can also be called open CU-CP (open-CU-CP, O-CU-CP), and CU-UP can also be called open CU-UP (open-CU-UP, O-CU-UP).

[0101] Figure 2A An example diagram of an O-RAN system is shown. Access network equipment communicates with the core network (CN) via a backhaul link and with user equipment (UE) via an air interface. Specifically, the BBU in the access network equipment communicates with the core network via the backhaul link, and the radio unit (RU) in the access network equipment communicates with at least one UE via the air interface. The BBU communicates with at least one RU via a fronthaul link; the BBU and RU may or may not be co-located. The BBU includes at least one control unit and at least one DU, which can communicate via at least one midhaul link. Of course, in practice, the O-RAN system may also include... Figure 2A Other components besides those shown.

[0102] Figure 2B The diagram illustrates the network element function division and protocol layer structure of an O-RAN device.

[0103] In some possible examples or schemes, the CU, as a logical node, carries the Radio Resource Control (RRC) layer, Service Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Protocol (PDCP) layer, and other control functions. The CU connects to other network nodes in the core network through interfaces, such as E2 interfaces. Optionally, the CU may also possess some core network functions. The CU (e.g., PDCP layer and above) connects to the DU (e.g., RLC layer and below) through interfaces, such as F1 interfaces. In some examples, these interfaces (e.g., F1 interfaces) can provide control plane (C-Plane) and user plane (U-Plane) functions, such as interface management, system information management, UE context management, and RRC message transmission. F1AP is the application protocol for the F1 interface, defining the signaling procedures for F1. The F1 interface supports control plane F1-C and user plane F1-U.

[0104] In some possible examples or scenarios, the CU can be divided into CU-CP and CU-UP. CU-CP is a logical node responsible for the RRC layer and the control plane part of PDCP (PDCP-C) layer, used to implement the CU's control plane functions. CU-CP can interact with other network elements in the core network, which implement control plane functions, such as the access and mobility management function (AMF) in 5G systems. The AMF network element is responsible for mobility management in the mobile network, including location updates, network registration, and handover for terminal devices. CU-UP is a logical node responsible for the SDAP layer and the user plane part of PDCP (PDCP-U) layer, used to implement the CU's user plane functions. CU-UP can interact with other network elements in the core network, which implement user plane functions, such as the UPF in 5G systems. The UPF is responsible for data forwarding and receiving in terminal devices.

[0105] The above CU and DU configurations are merely examples; actual configurations can be adjusted as needed. For instance, a CU or DU can be configured to have more protocol layer functions, or it can be configured to have only partial protocol layer processing functions. For example, some RLC layer functions and protocol layer functions above the RLC layer can be placed on the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed on the DU. The functions of the CU or DU can also be divided according to service type or other system requirements, such as by latency. Functions requiring low latency can be placed on the DU, while functions not requiring this latency can be placed on the CU. In some possible examples or schemes, the DU is a logical node carrying the radio link control (RLC) layer, medium access control (MAC) layer, higher physical layer (Higher PHY) layer, and other functions. In some examples, the DU can control at least one RU. The DU connects to the RU through interfaces, which can be fronthaul interfaces. In some examples, the Higher PHY layer includes parts of the PHY layer that handle processes such as forward error correction (FEC) encoding and decoding, scrambling, modulation, and demodulation.

[0106] In some possible examples or scenarios, the RU is a logical node that carries both lower physical layer (LowerPHY) and radio frequency (RF) processing. In some examples, the RU can be a 3GPP transmission reception point (TRP), a remote radio head (RRH), or other similar entities. In some examples, the Low-PHY includes portions of the PHY processing, such as Fast Fourier Transform (FFT), Inverse Fast Fourier Transform (IFFT), digital beamforming, and filtering. The RU communicates with one or more UEs via a radio link.

[0107] DUs and RUs can be deployed co-located or geographically. DUs and RUs exchange information between the control plane and user plane via a lower-layer split CUS-plane (LLS-CUS) interface using a fronthaul link. The LLS-CUS interface can contain two sub-interfaces: the LLS-C interface and the LLS-U interface, responsible for communication between the control plane (C-Plane) and user plane (U-Plane), respectively. The control plane (C-Plane) primarily handles real-time control information between the DU and RU, while the user plane (U-Plane) is responsible for user data transmission. In addition, DUs and RUs exchange management information via the LLS-M interface. The management plane (M-Plane) handles non-real-time management operations between the DU and RU, such as configuration updates and status monitoring. DUs and RUs can collaborate to perform physical layer (PHY) functions. A DU can connect to one or more RUs, and the functions of DUs and RUs can be flexibly configured according to design requirements. For example, a DU can be configured to implement baseband processing, while an RU can be configured to implement mid-frequency (RF) functions. Alternatively, the DU can be configured to implement higher-level physical layer functions, such as those closer to the MAC layer, while the RU can be configured to implement lower-level physical layer functions, including even RF functions. Higher-level physical layer functions typically involve parts closer to the MAC layer, while lower-level functions involve parts closer to the mid-RF side.

[0108] Wireless access network equipment can be macro base stations (such as...) Figure 1 110a in the text), can also be a micro base station or an indoor station (such as... Figure 1 110b) in the text can also be a relay node or a donor node, etc. The embodiments of this application do not limit the specific technology or device form used in the wireless access network equipment. For ease of description, the following description uses a base station as an example of a wireless access network device.

[0109] Figure 3 This diagram illustrates a possible RAN chip architecture, comprising three parts: CU, DU, and RU. The CU is a platform that performs upper-layer L2 and L3 functions. Midhaul and Backhaul interfaces carry traffic between the CU and DU, as well as between the CU and the core network. The DU performs L1 and some L2 functions, while the RU performs L1 computation and RF digital functions; the Fronthaul and Backhaul interfaces carry traffic between the RU and DU, and between the CU and DU. An integrated DU combines the functions of both the DU and RU.

[0110] The CU / DU hardware includes a chassis platform, motherboard, peripherals, and cooling system. The motherboard contains processing units, memory, internal I / O interfaces, and external connection ports. Its hardware accelerator is designed with interfaces, and hardware functional components include: storage for software, hardware, and system debugging interfaces, and a single-board management controller.

[0111] DU systems are typically implemented using multi-core processors and one or more hardware accelerators. Parts of the DU protocol stack can be implemented in software running on the multi-core processor, while computationally intensive L1 and L2 functions can be offloaded to hardware accelerators based on off-the-shelf field-programmable gate arrays (FPGAs) / graphics processing units (GPUs); or all L1 functions can be offloaded to FPGA / GPU-based hardware accelerators, while other protocol stack components are implemented in software running on the processor; or the entire protocol stack can be implemented in software running on the processor. Hardware accelerators support interconnection with x86 or non-x86 processors. Similarly, accelerators have multi-channel PCIe interfaces pointing to the CPU and external connections via GbE.

[0112] RU consists of three parts:

[0113] The O-RAN Processing Unit (OPU) receives Enhanced Common Public Radio Interface (eCPRI) frames from the O-RAN fronthaul and performs fronthaul interface operations, the lowest level L1 (coding, scrambling, modulation, layer mapping, precoding), synchronization, beamforming, and resource unit mapping. The OPU can be implemented as a CPU, FPGA, or ASIC.

[0114] The O-RU's digital processing unit (DPU) performs synchronization, DDC (digital downconversion in UL), DUC (digital upconversion in DL), CFR, and DPD to improve power amplifier efficiency by reducing the peak-to-average power ratio (PAPR) / adjacent channel leakage power ratio (ACLR) of the RF front end; the DPU can be implemented as an FPGA or ASIC.

[0115] The O-RU's RF processing unit includes a transceiver module, up / down converters, power amplifiers (PA), low-noise amplifiers (LNA), and Tx / Rx filters. All conversions between the analog and digital domains (DAC and ADC) (e.g., RF sampling, frequency conversion using RF, IF, and LO mixing during up-conversion and down-conversion) are performed within the transceiver module. Note that physical and logical partitioning within the RF processing unit does not require specific boundaries.

[0116] Terminal devices can also be referred to as user equipment (UE), mobile stations, mobile terminal devices, etc. Terminal devices can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. Terminal devices can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, roadside units (RSUs), etc. The embodiments of this application do not limit the specific technologies or device forms used in the terminal devices.

[0117] Base stations and terminal equipment can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; on water; or in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the base stations and terminal equipment.

[0118] The roles of base stations and terminal devices can be relative, for example, Figure 1 The helicopter or drone 120i can be configured as a mobile base station. For terminal devices 120j that access the wireless access network 100 via 120i, terminal device 120i is a base station; however, for base station 110a, 120i is a terminal device, meaning that 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a base station-to-base station interface protocol; in this case, 120i is also a base station relative to 110a. Therefore, both base stations and terminal devices can be collectively referred to as communication devices. Figure 1 The 110a and 110b in the text can be referred to as communication devices with base station functions. Figure 1The 120a-120j in the text can be referred to as communication devices with terminal equipment functions.

[0119] Communication between base stations and terminal devices, between base stations, and between terminal devices can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can be conducted using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0120] In the embodiments of this application, the functions of the base station can be executed by modules (such as chips) within the base station, or by a control subsystem that includes base station functions. This control subsystem, including base station functions, can be a control center in the aforementioned application scenarios such as smart grids, industrial control, intelligent transportation, and smart cities. Similarly, the functions of the terminal device can be executed by modules (such as chips or modems) within the terminal device, or by a device that includes terminal device functions.

[0121] The core network involved in this application embodiment may include network devices that process and forward user signaling and data. For example, it may include access and mobility management functions (AMF), session management functions (SMF), user plane gateways, location management devices, etc. Of course, the core network may also include other network elements, which are not listed here.

[0122] It is understood that the network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0123] The following describes some of the technical features involved in this application.

[0124] I. Low-power wake-up radio (LP-WUR) mechanism:

[0125] The wake-up radio mechanism can be understood as a function to reduce the power consumption of the UE. For the UE, low-power wake-up radio refers to the introduction of a low-power (LP) interface on the basis of a traditional main receiver (MR) (or main radio (MR) or main module, etc.). This LP interface is implemented through a simple circuit or chip with low power consumption. The specific form of the LP interface is not limited in the embodiments of this application. For example, the LP interface can be implemented through a wake-up receiver (WUR), a low-power wake-up receiver (LP-WUR), a low-power radio (LR), a wake-up module, or a wake-up circuit. The LP interface can also be called an auxiliary receiver, auxiliary module, or auxiliary circuit, etc. In this document, LR and LP-WUR, WUR, wake-up module, wake-up circuit, auxiliary receiver, auxiliary module, or auxiliary circuit, etc., are interchangeable.

[0126] For ease of description, the following text will use MR and LR as examples, such as Figure 4 As shown.

[0127] The MR (Mobile Controller) is primarily used for sending and / or receiving data / signaling. If there is no need for sending and / or receiving data / signaling, the MR can be turned off or placed in a sleep state or sleep mode. The LR (Low Reception Controller) can be used to wake up a sleep MR; for example, when there is a need for sending and / or receiving data / signaling, the LR wakes up the MR. This design reduces the power consumption of the UE.

[0128] The signal received by the LR can be referred to as a low-power signal, a wake-up signal (WUS), or a low-power wake-up signal (LP-WUS), etc. In this article, LP-WUS can be used interchangeably with WUS, low-power signal, or wake-up signal.

[0129] II. LR Measurement:

[0130] Since the reception performance of the LR is generally worse than that of the MR, LP-WUS monitoring (or detection) via the LR is usually only enabled when the signal quality of the serving cell (or service area) is relatively good. Otherwise, the UE may not be able to properly demodulate LP-WUS at the cell edge, resulting in missed paging. Furthermore, since the LR does not support neighboring cell measurements, the MR needs to be woken up to perform neighboring cell measurements when the UE is at the cell edge to avoid affecting the timeliness of cell reselection. Therefore, in addition to receiving LP-WUS, the LR also needs to measure the serving cell to support the UE in evaluating the quality of the serving cell. This measurement is performed on the low-power synchronization signal (LP-SS) or the synchronization signal and physical broadcast channel block (SSB).

[0131] III. Entry and exit of LP-WUR monitoring (or LP-WUR detection), case 1, and case 3:

[0132] As shown in Table 1, 3GPP RAN2 defines the entry and exit conditions for three types of LR-related events (or states):

[0133] 1. LP-WUS Monitoring: This refers to LR monitoring of LP-WUS as mentioned above, where MR's paging monitoring function is disabled or dormant. Entry conditions for LP-WUS monitoring include an MR threshold, optionally including an LR threshold. If the network only configures an MR threshold in the entry conditions, the UE can start LR monitoring of LP-WUS and stop MR paging monitoring when the MR's measurement result of the serving cell is higher than the MR threshold. If the network configures an LR threshold, the entry conditions are considered met only when both the MR's measurement result of the serving cell and the LR's measurement result of the serving cell are higher than the LR threshold. After the UE enters LP-WUS monitoring, if the LR's measurement result of the serving cell is lower than the LR threshold included in the exit conditions, the UE must wake up MR to monitor paging.

[0134] 2. Case 1, i.e., Radio Resource Management Measurement Fully Offloading. In this state, the MR completely stops measuring the serving cell and neighboring cells, while the LR measures the serving cell. The entry conditions for fully offloading radio resource management measurements include the MR threshold, and optionally include the LR threshold.

[0135] After the UE enters the complete offload of radio resource management measurement, when the LR measurement result of the serving cell is lower than the LR threshold included in the exit condition, the UE exits the complete offload of radio resource management measurement, and the MR measures the serving cell and neighboring cells.

[0136] 3. Case 3, or Radio Resource Management (RRM) measurement relaxation. In this state, MR measures the serving cell and neighboring cells in a relaxed mode. This allows the UE to measure and evaluate the serving cell at a sparser frequency and to complete the search, measurement, and evaluation of neighboring cells with greater latency, for example, relaxing the currently customized metrics by 16 times. In this state, LR measures the serving cell. The entry conditions for RRM measurement relaxation include an MR threshold, and optionally an LR threshold.

[0137] After the UE enters the radio resource management measurement relaxation, when the LR's measurement result of the serving cell is lower than the LR threshold included in the exit condition, the UE exits the radio resource management measurement relaxation, and the MR measures the serving cell and neighboring cells in normal mode.

[0138] Table 1

[0139]

[0140] It is understood that the entry conditions for the above three states are independent, and the exit conditions for the above three states are also independent. However, it is possible that two or three of the above three states correspond to the same entry and / or exit conditions. The entry / exit behaviors of Case 1 and Case 3 are similar to those monitored by LP-WUS. The coverage area of ​​Case 1, the coverage area of ​​Case 3, and the cell coverage area are illustrated as follows. Figure 5 As shown, the coverage area of ​​Case 1 (if the network is configured with Case 1) <= the coverage area of ​​Case 3 (if the network is configured with Case 3) <= the cell coverage area.

[0141] IV. MR Measurement Indicators:

[0142] If the UE does not enter Case 1 or Case 3, it is considered to be in legacy mode. In legacy mode, MR measurement is enabled and LR measurement is disabled.

[0143] 3GPP RAN4 defines the metrics for MR measurement of serving and neighboring cells when the UE is in legacy state.

[0144] For example, Section 4.2.2.2 of TS38.133 defines the metrics for MR (Mean-Modified) measurement of serving cells, mainly including the frequency of UE measurement and evaluation of serving cells. For instance, when the DRX period is 1.28s, the UE measures and evaluates the serving cell once per DRX period. The purpose of measurement and evaluation is to determine whether the serving cell meets the S criterion (the S criterion is an important standard used in cell selection and cell search to determine whether a cell is suitable for camping. In specific implementations, the S criterion can also be called criterion S, S standard, or cell selection criterion S, etc.). If N consecutive N serv If the evaluation results are all unsatisfactory, the UE will trigger the MR to search, measure and evaluate neighboring cells in order to perform cell reselection.

[0145] Note that the neighbor cell measurement triggered under this condition differs from the neighbor cell measurement behavior defined in Section 4.2.2.3 / 4 below. Since the serving cell is unavailable at this time, although not explicitly specified in the standard, it is generally assumed that the UE will complete the search and measurement of neighbor cells within a short delay, or at a faster frequency, such as once per SSB-based measurement timing configuration (SMTC) cycle. For ease of description, this paper refers to the neighbor cell measurement triggered under this condition as "fast neighbor cell measurement".

[0146] The following is described in section 4.2.2.2 of TS38.133:

[0147]

[0148] Section 4.2.2.3 / 4 of TS38.133 defines the metrics for MR (Measuring and Measure) of co-frequency and inter-frequency neighboring cells. These metrics primarily include the UE's search, measurement, and evaluation of neighboring cell latency. The purpose of the UE's evaluation of neighboring cells is to determine if any neighboring cells meet the cell reselection criteria. For example, with a DRX period of 1.28s, the UE needs to search, measure, and evaluate whether a newly emerging co-frequency neighboring cell meets the cell reselection criteria within 32s. For co-frequency cells already found, the UE needs to measure every 1.28s and evaluate whether the cell meets the cell reselection criteria within 6.4s.

[0149]

[0150] Among them, T detect,NR_Intra The time or period for a terminal device to evaluate whether a newly emerging co-frequency neighboring cell meets the cell reselection criteria; T measure,NR_Intra For terminal equipment, measure the time or period of a detected co-frequency neighboring cell; T evaluate,NR_IntraThe time or period for a terminal device to evaluate whether a detected co-frequency neighboring cell meets the cell reselection criteria. detect,NR_Intra T measure,NR_Intra T evaluate,NR_Intra These correspond to the time (or period) for terminal devices to search, measure, and evaluate neighboring cells on the same frequency.

[0151] Correspondingly, T detect,NR_Inter The time or period for a terminal device to evaluate whether a newly emerging inter-frequency neighboring cell meets the cell reselection criteria; T measure,NR_Inter For terminal equipment, measure the time or period of a detected inter-frequency neighboring cell; T evaluate,NR_Inter The time or period for a terminal device to evaluate whether a detected inter-frequency neighboring cell meets the cell reselection criteria. detect,NR_Inter T measure,NR_Inter T evaluate,NR_Inter These correspond to the time (or period) for terminal devices to search, measure, and evaluate neighboring cells at different frequencies.

[0152] As can be seen from the above indicators, in order to achieve power saving for the UE in idle / inactive states, when the serving cell is in a normal state, the UE's measurement and evaluation of the serving cell, as well as its search, measurement, and evaluation of neighboring cells, are all performed in units of DRX cycles. The candidate values ​​for the DRX cycle are {0.32, 0.64, 1.28, 2.56} s, meaning that the UE is not required to perform search, measurement, and evaluation in units of SSB cycles or SMTC cycles. The candidate values ​​for the SSB or SMTC cycle are {0.005, 0.01, 0.02, 0.04, 0.08, 0.16} s. Within the time delay specified by the measurement indicators, the specific SSB or SMTC selected for measurement is determined by the UE implementation.

[0153] V. LR Measurement Indicators:

[0154] RAN4 defines the frequency of LR measurements when the UE is in Case 1 and Case 3 states: if the LR measures LP-SS, it measures once per LP-SS cycle; if the LR measures SSB, it measures once per DRX cycle or LP-WUS occasion (LO) cycle. According to the standard discussion, DRX cycles and LO cycles are in one-to-one correspondence; in the embodiments of this application, DRX cycles and LO cycles are interchangeable terms.

[0155] VI. Measurements after MR wake-up:

[0156] At the RAN4#114 meeting, it was proposed to perform measurements according to the SSB cycle instead of the DRX cycle after the MR is woken up and during the wake-up process. The goal is to enable the MR to receive paging as soon as possible, and a scenario where cell reselection needs to be performed immediately after the MR is woken up (the worst case) was proposed.

[0157] The following is a description of the proposal from the meeting:

[0158]

[0159]

[0160] However, the above scheme does not specify how long the measurement based on the SSB cycle should last. If the measurement is based on the SSB cycle continuously, there will be a problem of high power consumption. Furthermore, the above scheme does not specify whether cell reselection needs to be performed immediately after MR wake-up. If it is assumed that cell reselection and rapid neighbor cell measurement (such as searching, measuring and evaluating neighbor cells according to the SMTC cycle) should be performed immediately after MR wake-up, but cell reselection is not actually required, it will bring additional power consumption. If it is assumed that cell reselection does not need to be performed immediately after MR wake-up and neighbor cells are searched, measured and evaluated according to the DRX cycle, there is a problem that the search, measurement and evaluation of neighbor cells are not timely, resulting in untimely cell reselection and the problem of UE missing paging.

[0161] The RAN4#114 meeting also proposed that the LR should evaluate the S criterion. The scenario considered is to measure and evaluate the serving cell based on the LR when the serving cell quality is poor. The goal is to save the time of measuring and evaluating whether the serving cell meets the S criterion based on the MR according to the DRX cycle after the LR exits, so as to enable fast neighbor cell measurement (such as searching, measuring and evaluating neighboring cells according to the SMTC cycle) to be started directly after the MR is woken up.

[0162] The following is a description of the proposal from the meeting:

[0163]

[0164]

[0165] While the above scheme can assess whether the serving cell meets the S criterion based on LR before MR wake-up, thus enabling fast neighbor cell measurement to be started directly after MR wake-up, this technology has a problem. The fact that the serving cell does not meet the S criterion based on LR assessment does not mean that it does not meet the S criterion based on MR assessment. For example, in the presence of adjacent channel interference, even if the signal quality of the serving cell is good, the weak anti-interference capability of LR may lead to a misjudgment of the serving cell's quality as poor, triggering unnecessary fast neighbor cell measurement and resulting in wasted power.

[0166] To address one or more of the aforementioned technical problems, embodiments of this application provide a cell assessment method. See also... Figure 6 The flowchart below illustrates the method, which can be executed by a terminal device or by an internal chip or module of the terminal device. The following example demonstrates the method being executed by a terminal device. The method includes the following steps S101–S102:

[0167] S101. Determine if the exit condition of the first state is met. Optionally, S101 can be replaced by: Determine if the entry condition of the second state is met.

[0168] The first state is any state related to MR measurement. For example, the first state may include at least one of the following: LP-WUS monitoring, complete RRM measurement offloading, and RRM measurement relaxation. The specific definitions of these three states, and the exit conditions corresponding to each state, can be found in Table 1 above, and will not be repeated here. After the exit conditions of the first state are met, the MR of the terminal device needs to be woken up; or, in other words, after exiting the first state, the terminal device is in a woken-up state.

[0169] The second state is the state of the terminal device after it exits the first state. The entry conditions for the second state correspond to (or are the same as) the exit conditions for the first state. After the entry conditions for the second state are met, the MR of the terminal device needs to be woken up; or in other words, after entering the second state, the terminal device is in a woken-up state.

[0170] S102. After the first time period, within the second time period, evaluate the S criterion of the serving cell based on the first cycle using MR. Optionally, S102 can be replaced with: After the first time period, within the second time period, evaluate the S criterion of the serving cell based on the first cycle.

[0171] It is understood that evaluating a serving cell via MR specifically refers to evaluating the serving cell based on the measurement results of the serving cell using MR. Evaluating the S-criteria of the serving cell via MR based on a first cycle, for example: measuring the serving cell via MR in each first cycle and evaluating the S-criteria of the serving cell based on the measurement results. In some embodiments, evaluating the S-criteria of the serving cell via MR based on a first cycle can be alternatively described as measuring and evaluating the S-criteria of the serving cell via MR based on a first cycle.

[0172] In some scenarios, the S criterion for evaluating the serving cell based on the first cycle is by default determined by the S criterion for evaluating the serving cell based on the first cycle via MR. Therefore, "S criterion for evaluating the serving cell based on the first cycle via MR" and "S criterion for evaluating the serving cell based on the first cycle" can be used interchangeably.

[0173] The first duration is less than or equal to the wake-up latency of the MR (i.e., the time taken to switch from the off (or sleep) state to the wake-up state, which can be defined as the time between the LR receiving the LP-WUS and the MR being able to monitor paging). The wake-up latency can include the ramping up duration and the synchronization duration. The ramping up duration can be understood as the hardware startup and loading time of the MR, typically tens or hundreds of milliseconds; the synchronization duration can be understood as the time for time and frequency synchronization after the MR starts up, typically 3 to 5 SSB cycles. The wake-up latency can be communicated to the network by the terminal device through UE capabilities. The first duration can be equal to the wake-up latency, equal to the ramping up duration, or a value less than the wake-up latency.

[0174] The first period is a positive integer multiple of the serving cell's SSB period. In practice, the first period can be set to be less than the DRX period.

[0175] For example, the first cycle = SSB cycle, thereby accelerating the efficiency of the S criterion for evaluating the serving cell after MR wake-up.

[0176] Or, for example, the first period = N * SSB period, where N is a positive integer. The value of N can be related to the SSB period. For example, when the SSB period is 5ms, N = 4; when the SSB period is 10ms, N = 2; when the SSB period is greater than or equal to 20ms, N = 1. This is equivalent to the first period being max(20ms, SSB period).

[0177] The above scheme, after the terminal device exits the first state, evaluates the serving cell's S-criteria based on the first cycle using MR. This allows for a rapid determination of whether the current serving cell is suitable for camping (i.e., a rapid determination of whether cell reselection is needed) after MR wake-up, avoiding the problem of missed paging due to untimely serving cell measurement and evaluation leading to untimely cell reselection. Furthermore, this scheme limits the evaluation of the serving cell's S-criteria based on the first cycle to the second time period, avoiding the power consumption waste caused by prolonged evaluation based on the first cycle. In addition, compared to evaluating the serving cell's S-criteria using LR, evaluating the serving cell's S-criteria using MR avoids the impact of adjacent channel interference on the evaluation results, ensuring the accuracy of the evaluation results. In summary, the embodiments of this application can balance the timeliness and accuracy of cell evaluation with the energy-saving effects of the terminal device.

[0178] In one possible design, if the serving cell does not meet the S criterion in multiple consecutive SSB cycles, then the UE shall initiate the measurements of all neighbor cells indicated by the serving cell, regardless of the measurement rules currently limiting UE measurement activities.

[0179] Under normal circumstances, terminal equipment measurement activities should follow terminal equipment measurement rules. For example, when the serving cell is in a normal state, the terminal equipment's measurement and evaluation of the serving cell, as well as its search, measurement, and evaluation of neighboring cells, are performed in units of DRX cycles. The statement "Regardless of the current measurement rules restricting terminal equipment measurement activities, initiate measurements of all neighboring cells indicated by the serving cell" can be understood as follows: the terminal equipment no longer follows the measurement rules for terminal equipment measurement activities. For example, the terminal equipment's search, measurement, and evaluation of neighboring cells are not performed in units of DRX cycles, but rather in units of shorter cycles (such as the first cycle, SSB cycle, or SMTC cycle) (i.e., initiating fast neighbor cell measurement).

[0180] Conversely, if the serving cell satisfies the S criterion at least once in multiple consecutive SSB cycles, then the terminal device measurement rules must be followed. For example, the terminal device can measure and evaluate the serving cell according to the DRX cycle, and search, measure and evaluate neighboring cells according to the DRX cycle.

[0181] The above design clarifies the specific scheme for determining whether cell reselection needs to be performed immediately after MR wake-up (i.e., whether fast neighbor cell measurement needs to be triggered). This is based on the S criterion. Generally, the worse the quality of the serving cell assessed by the terminal device, the more timely the terminal device needs to perform cell reselection to ensure communication continuity. In the above design, when the serving cell does not meet the S criterion for multiple consecutive SSB cycles, the terminal device initiates fast neighbor cell measurement. This allows for timely initiation of fast neighbor cell measurement when cell reselection is needed, and avoidance of fast neighbor cell measurement when cell reselection is not needed (e.g., measuring the serving cell and neighboring cells using the DRX cycle when cell reselection is not needed). This approach balances the timeliness and accuracy of cell assessment with energy-saving effects for the terminal device.

[0182] In one possible design, the second duration is equal to N consecutive times. servThe duration of each SSB cycle, N serv N is a positive integer. serv The value can be predefined, such as as specified in the protocol.

[0183] In this case, if the serving cell is in consecutive N serv If the S criterion is not met in any of the SSB cycles (i.e., all assessments within the second duration), then the UE shall initiate the measurements of all neighbor cells indicated by the serving cell, regardless of the measurement rules currently limiting UE measurement activities. For example, the UE may search, measure, and assess neighbor cells through MR based on the first cycle, the SSB cycle, or the SMTC cycle.

[0184] N serv It can be related to the SSB period. For example, the larger the SSB period, the more N... serv The smaller or unchanged. For example, Table 2 is one possible example.

[0185] Table 2

[0186]

[0187] Of course, the above is just an example, and the actual situation is not limited to this.

[0188] In this design, the second duration is determined by the number of measurements N. serv It is limited and simple to implement; at the same time, it can minimize the time spent on measuring and evaluating the serving cell based on the first cycle, thus saving power consumption of terminal equipment.

[0189] In one possible design, the second duration is T, which can be configured by the network.

[0190] In this case, if the serving cell is in consecutive N servN SSB periods within one SSB period do not satisfy the S criterion, the UE shall initiate the measurements of all neighbour cells indicated by the serving cell, regardless of the measurement rules currently limiting UE measurement activities. For example, the UE searches for, measures, and evaluates neighboring cells through MR based on the first period, SSB period, or SMTC period.

[0191] wherein N serv = T / SSB period. Wherein N may be configured by the network.

[0192] In this design, the second duration is configured by the network, making the network's management of measurement tasks more flexible. For example, when the network expects the UE to have a longer time to measure and evaluate the quality of the serving cell, T can be configured to be larger; when the network expects the UE to be more energy-efficient, T can be configured to be smaller.

[0193] In a possible design, when a first condition is satisfied, S102 is executed (i.e., the S criterion of the serving cell is evaluated through MR based on the first period). For ease of description, evaluating the S criterion of the serving cell through MR based on the first period is referred to herein as "fast evaluating the serving cell".

[0194] The first condition includes but is not limited to at least one of the following:

[0195] 1) The first state includes that RRM measurement is fully offloaded and no RRM measurement relaxation is configured by the network; or, the first state includes RRM measurement relaxation;

[0196] From Figure 5 it can be seen that the position of the UE during RRM measurement relaxation is closer to the edge of the serving cell than the position of the UE when RRM measurement is fully offloaded. If this condition is satisfied, it indicates that the UE is triggered to wake up by MR due to a position change, the probability that the UE is located at the edge of the serving cell is relatively high, and the possibility of cell reselection after waking up is relatively high.

[0197] 2) The threshold in the MR threshold-S criterion in the entry condition for the first state < X, where X ≥ 0;

[0198] If this condition is satisfied, it indicates that the position of the UE in the first state is relatively close to the edge of the serving cell, and the possibility of cell reselection after waking up is relatively high.

[0199] 3) Before the exit condition of the first state is met, the measurement result of LR is < the first LR threshold. Wherein, the first LR threshold is > or ≥ the LR threshold in the exit condition of the first state. The first LR threshold can be determined by network configuration or protocol predefined or according to the LR threshold corresponding to the criterion, without restriction.

[0200] If this condition is met, it indicates that the terminal device is likely located at the edge of the serving cell, and the possibility of cell reselection after wake-up is relatively high.

[0201] Of course, the above are just examples of the first condition, and the actual situation is not limited to this.

[0202] Optionally, if the first condition is not met and / or the second condition is met, it indicates that the terminal device is not far from the serving base station, or that the terminal device is likely located in the center of the serving cell, and the possibility of cell reselection is low, thus the timeliness requirement for serving cell measurement and evaluation is lower. In this case, rapid evaluation of the serving cell is not required. For example, the terminal device can follow its measurement rules, measuring and evaluating the serving cell according to the DRX cycle, and searching, measuring, and evaluating neighboring cells according to the DRX cycle.

[0203] The second condition may include any of the following:

[0204] 1) The first state includes LP-WUS monitoring, and exiting the first state is due to the terminal device receiving an LP-WUS trigger;

[0205] If this condition is met, the terminal device is triggered to wake up by MR due to service reasons rather than location changes, and the possibility of cell reselection after wake-up is relatively small.

[0206] 2) The first state includes complete RRM measurement offloading and does not meet the exit condition of network not being configured with RRM measurement relaxation.

[0207] If this condition is met, the probability that the terminal device is located at the edge of the serving cell is relatively small, and the possibility of cell reselection after wake-up is also relatively small.

[0208] Of course, the above are just examples of the second condition, and the actual situation is not limited to this.

[0209] The above design enables the serving cell to be evaluated in the first cycle when cell reselection is required, thus achieving rapid evaluation of the serving cell. When cell reselection is not required, rapid evaluation of the serving cell is avoided as much as possible (e.g., evaluating the serving cell in the DRX cycle), further saving terminal equipment power consumption.

[0210] In another possible design, S102 is executed by default when the exit condition of the first state is met. This design can reduce the complexity of implementation.

[0211] It is understandable that the above implementation methods can be implemented individually or in combination.

[0212] To better understand the above solution, another example is provided below. (See...) Figure 7 This includes the following steps S201 to S206:

[0213] S201, The terminal device determines to wake up the MR.

[0214] Scenarios where terminal devices wake up MR, for example:

[0215] Scenario 1: LR receives LP-WUS;

[0216] Scenario 2: The exit conditions of Case 1 are met, and the network is not configured with Case 3;

[0217] Scenario 3: The exit conditions of Case 1 are met, but the exit conditions of Case 3 are not met;

[0218] Scenario 4: The exit conditions of Case 3 are met.

[0219] S202. The terminal device determines whether a rapid assessment of the serving cell is required; if so, proceed to S203; otherwise, proceed to S206.

[0220] Specifically, if the first condition is met, a rapid assessment of the serving cell is required; if the first condition is not met and / or the second condition is met, a rapid assessment of the serving cell is not required. The first and second conditions can be found above and will not be repeated here.

[0221] It is understandable that S202 is an optional step, and in fact, S203 can be executed directly after S201, meaning that a quick evaluation of the serving cell is required by default.

[0222] S203. After the first condition has been met for a first period of time, within a second period of time, the terminal device evaluates the S criterion of the serving cell based on the first cycle through MR.

[0223] For a detailed implementation of S203, please refer to S102 above.

[0224] S204. Based on the evaluation results of S203, the terminal device determines whether it is necessary to initiate fast neighbor cell measurement; if so, it executes S205; otherwise, it executes S206.

[0225] For example, the serving cell is in N consecutive serv If none of the SSB cycles satisfy the S criterion, or if the serving cell fails to satisfy the S criterion for any of the N consecutive SSB cycles, then the serving cell fails to satisfy the S criterion for any of the N consecutive SSB cycles. servIf N SSB cycles do not meet the S criterion, then fast neighbor cell measurement needs to be initiated. For specific judgment methods, please refer to the above text.

[0226] S205. The terminal equipment searches, measures and evaluates neighboring cells based on the first cycle (such as the SSB cycle or SMTC cycle) using MR.

[0227] S206. The terminal equipment measures and evaluates the serving cell based on the DRX cycle through MR, and searches, measures and evaluates neighboring cells based on the DRX cycle through MR.

[0228] The above example enables timely and on-demand triggering of fast neighbor cell measurements after MR wake-up. For instance, in scenarios where LR coverage and cell coverage are the same, it avoids the problem of missed paging due to delayed neighbor cell measurement triggering leading to untimely cell reselection. It also avoids the high power consumption caused by triggering unnecessary or prolonged fast neighbor measurements. Furthermore, the terminal device's determination of whether fast neighbor cell measurements are needed after MR wake-up is based on MR measurements, avoiding the power consumption issues caused by unnecessary triggering that might result from directly triggering fast neighbor cell measurements using LR measurements. Moreover, compared to the latency of directly triggering fast neighbor cell measurements based on LR measurements, the latency of determining whether fast neighbor cell measurements are needed after MR wake-up based on LR measurements is very small (e.g., 160-320ms).

[0229] In legacy mode, terminal devices may require both LR and MR measurements. However, a solution for simultaneous LR and MR measurements is still unclear.

[0230] It is understood that the simultaneous measurement of LR and MR referred to in this article means that there are both LR and MR measurements within a certain period of time. Depending on the network configuration, the measurement resources of MR and LR may overlap or not overlap during this period of time.

[0231] Specifically, LR and MR are implemented based on different circuits and may not be able to receive simultaneously. Therefore, when the measurement resource timing of an MR and the measurement resource timing of an LR overlap in time, LR and MR may not be able to use their respective measurement resource timings simultaneously. In the embodiments of this application, the measurement resource timing may be simply referred to as the measurement timing.

[0232] For example, Figure 8This is an example diagram illustrating a possible MR measurement timing. The network-configured measurement resources include: intra-frequency SMTC, inter-frequency SMTC, serving cell SSB, and serving cell LP-SS. Figure 8 Each resource corresponds to a pattern block representing the measurement timing for that resource. The same-frequency SMTC timing is used for MR measurement of the SSB of neighboring cells (hereinafter referred to as same-frequency neighboring cells) that share the same frequency (i.e., the same carrier frequency) as the serving cell. The different-frequency SMTC timing is used for MR measurement of the SSB of neighboring cells (hereinafter referred to as different-frequency neighboring cells) that share a different frequency (i.e., different carrier frequency) as the serving cell. The serving cell SSB timing can be used for MR or LR measurement of the serving cell's SSB. The serving cell LP-SS timing can be used for LR measurement of the serving cell's LP-SS. It should be understood that in overlapping measurement timings, only one of LR and MR may be used for measurement.

[0233] exist Figure 8 The diagram illustrates the configuration of the above measurement resources within a 640ms timeframe: the period for the same-frequency SMTC timing (hereinafter referred to as the same-frequency SMTC period), the period for the different-frequency SMTC timing (hereinafter referred to as the different-same-frequency SMTC period), and the period for the serving cell SSB timing (hereinafter referred to as the SSB period) are all 160ms, while the period for the serving cell LP-SS timing (hereinafter referred to as the LP-SS period) is 320ms.

[0234] exist Figure 8 In the scenario shown, MR measurement occupies the measurement opportunity within each 160ms period (i.e., within each SMTC cycle, specifically a same-frequency SMTC cycle or a different-frequency SMTC cycle). This results in a conflict between LR and MR measurement opportunities within the 640ms timeframe, regardless of which SSB or LP-SS cycle the LR measurement occupies. In other words, there is no available LR measurement opportunity within the 640ms timeframe. It is unclear how long it takes for the terminal device to simultaneously complete LR and MR measurements, increasing the latency for the terminal device to transition from legacy state to LP-WUR monitoring, case 1, or case 3 states. Furthermore, LR measurement may prevent MR measurement, hindering timely cell reselection and impacting the terminal device's communication performance.

[0235] In view of this, embodiments of this application also provide a cell assessment method that can clarify the scheme for simultaneous measurement of LR and MR.

[0236] Before introducing the specific methods, let's first introduce the operations that can be performed on each cell based on LR and MR:

[0237] (1) Based on LR, at least one of the following can be performed on the serving cell: measurement and evaluation. It is understood that the period for performing measurement and the period for performing evaluation on the serving cell based on LR can be different.

[0238] (2) Based on MR, at least one of measurement and evaluation can be performed on the serving cell. It is understood that the cycle for performing measurement and the cycle for performing evaluation on the serving cell by MR can be different.

[0239] (3) Based on MR, at least one of the following can be performed on neighboring cells: search, measurement, and evaluation. It is understood that any two of the following can be different: the period for performing a search on neighboring cells based on MR, the period for performing a measurement on neighboring cells based on MR, and the period for performing an evaluation on neighboring cells based on MR.

[0240] Neighboring cells can be divided into two types: co-frequency neighboring cells and inter-frequency neighboring cells. MR can perform at least one of the following on co-frequency neighboring cells: search, measurement, and evaluation. It can also perform at least one of the following on inter-frequency neighboring cells: search, measurement, and evaluation. MR can also perform at least one of the following on both co-frequency neighboring cells and inter-frequency neighboring cells simultaneously.

[0241] For the sake of brevity, the following text will primarily use examples of LR performing measurement and evaluation on the serving cell, MR performing measurement and evaluation on the serving cell, and MR performing search, measurement, and evaluation on neighboring cells. However, in reality, LR can perform at least one of the following on the serving cell: measurement and evaluation; MR can perform at least one of the following on the serving cell: measurement and evaluation; and MR can perform at least one of the following on neighboring cells: search, measurement, and evaluation. Therefore, in the following text, "measurement and evaluation" performed by LR on the serving cell can be substituted with "measurement" or "evaluation," and "search, measurement, and evaluation" performed by MR on the serving cell can be substituted with "search," "measurement," "evaluation," "search and measurement," "measurement and evaluation," "search and evaluation," "search, measurement, and evaluation," etc.

[0242] See Figure 9 This is a flowchart of another cell evaluation method provided in an embodiment of this application. This method can be executed by a terminal device or by an internal chip or module of the terminal device. The following example illustrates the method being executed by a terminal device. The method includes S301 to S302:

[0243] S301, Receive first configuration information, second configuration information and third configuration information.

[0244] The first configuration information is used to configure the first measurement resources, which are used for measurement and evaluation of the serving cell based on the LR (Local Level). The first measurement resources include reference signals used for measurement and evaluation of the serving cell based on the LR, such as LP-SS or SSB. The first configuration information is also used to configure the period and offset of the first measurement resources.

[0245] The second configuration information is used to configure the second measurement resources, which are used for measurement and evaluation of the serving cell based on MR. The second measurement resources include reference signals, such as SSBs, used for measurement and evaluation of the serving cell based on MR. The second configuration information is also used to configure the period and offset of the second measurement resources.

[0246] The third configuration information is used to configure the third measurement resources, which are used for searching, measuring, and evaluating neighboring cells based on MR. The third measurement resources include reference signals used for searching, measuring, and evaluating neighboring cells based on MR, such as in-frequency SMTC and inter-frequency SMTC. The third configuration information is also used to configure the period and offset of the third measurement resources. The third measurement resources can be configured on a frequency-by-frequency basis.

[0247] It is understood that a terminal device can simultaneously receive the first configuration information, the second configuration information, and the third configuration information, such as the first configuration information, the second configuration information, and the third configuration information being carried in different fields of the same system message; the terminal device can also receive the first configuration information, the second configuration information, and the third configuration information sequentially at different times, such as the first configuration information, the second configuration information, and the third configuration information being carried in different system messages. This application does not restrict the specific method by which the terminal device receives the first configuration information, the second configuration information, and the third configuration information, but depends on the network's transmission behavior.

[0248] S302. Based on the first configuration information, the second configuration information, and the third configuration information, perform measurement and evaluation of the serving cell based on LR in the second period, perform measurement and evaluation of the serving cell based on MR in the third period, and perform search, measurement, and evaluation of neighboring cells based on MR in the fourth period. Optionally, S302 can be replaced by: based on the first configuration information, the second configuration information, and the third configuration information, perform measurement and evaluation of the serving cell in the second period, perform measurement and evaluation of the serving cell in the third period, and perform search, measurement, and evaluation of neighboring cells in the fourth period.

[0249] In some scenarios, the measurement and evaluation of the serving cell in the second cycle is performed by default based on LR in the second cycle, the measurement and evaluation of the serving cell in the third cycle is performed by default based on MR in the third cycle, and the search, measurement and evaluation of neighboring cells in the fourth cycle is performed by default based on MR in the fourth cycle. Therefore, "performing the measurement and evaluation of the serving cell based on LR in the second cycle, the measurement and evaluation of the serving cell based on MR in the third cycle, and the search, measurement and evaluation of neighboring cells based on MR in the fourth cycle" and "performing the measurement and evaluation of the serving cell in the second cycle, the measurement and evaluation of the serving cell in the third cycle, and the search, measurement and evaluation of neighboring cells in the fourth cycle" can be interchanged.

[0250] The second cycle refers to the cycle in which measurements and assessments of the serving cell are performed based on the LR. If the LR measures the SSB, the second cycle is an integer multiple of the DRX or LP-WUS cycle. If the LR measures the LP-SS, the second cycle is an integer multiple of the LP-SS cycle or the DRX.

[0251] The third cycle refers to the cycle in which the serving cell is evaluated based on the MR (Mean Assessment). The third cycle can be an integer multiple of the DRX (Digital Reference Cycle) cycle.

[0252] The fourth cycle refers to the cycle in which neighboring cells are searched, measured, and evaluated based on MR (Mean Detection and Analysis). The fourth cycle can be an integer multiple of the DRX cycle.

[0253] When neighboring cells include both co-frequency and inter-frequency neighboring cells, the cycle for performing MR-based search, measurement, and evaluation of co-frequency neighboring cells can be the same as or different from the cycle for performing MR-based search, measurement, and evaluation of inter-frequency neighboring cells, without any restriction.

[0254] For ease of distinction, the cycle for performing search, measurement, and evaluation of co-frequency neighboring cells based on MR will be referred to as the fifth cycle, and the cycle for performing search, measurement, and evaluation of inter-frequency neighboring cells based on MR will be referred to as the sixth cycle. In other words, the fourth cycle can include the fifth cycle corresponding to co-frequency neighboring cells and the sixth cycle corresponding to inter-frequency neighboring cells; the fifth cycle and the sixth cycle can be the same or different.

[0255] In specific implementation, based on the first configuration information, the second configuration information, and the third configuration information, the following steps are performed: LR-based measurement and evaluation of the serving cell is performed in the second period; MR-based measurement and evaluation of the serving cell is performed in the third period; and MR-based search, measurement, and evaluation of neighboring cells is performed in the fourth period. This may include: determining the second, third, and fourth periods based on the first, second, and third configuration information; performing LR-based measurement and evaluation of the serving cell in the second period; performing MR-based measurement and evaluation of the serving cell in the third period; and performing MR-based search, measurement, and evaluation of neighboring cells in the fourth period.

[0256] It is understood that in the embodiments of this application, when the terminal device determines the second cycle (or determines the measurement timing for measuring and evaluating the serving cell based on LR), it not only considers the first measurement resources configured by the first configuration information, but also the second measurement resources configured by the second configuration information and the third measurement resources configured by the third configuration information. This makes it possible to determine the second cycle, the third cycle, and the fourth cycle so that within a certain period of time, there can be timings for measuring and evaluating the serving cell based on LR, timings for measuring and evaluating the serving cell based on MR, and timings for searching, measuring, and evaluating neighboring cells based on MR, thereby enabling simultaneous LR and MR measurements.

[0257] Method 1: LR takes measurements during periods when MR is not in use (or in other words, increases the cycle of LR measurement and evaluation of the serving cell).

[0258] In this case, the second period = N1*T detect T detect It is the period based on MR search and evaluation of whether new detectable co-frequency or inter-frequency cells meet the reselection conditions, where N1 is a positive integer.

[0259] Optional, record T detect_intra It is the period for searching and evaluating whether a new detectable co-frequency cell meets the reselection criteria based on MR, denoted as T. detect_inter It is the cycle based on MR search and evaluation to determine whether new detectable inter-frequency cells meet the reselection criteria, T detect It can be equal to T detect_intra , can be equal to T detect_inter It can also be equal to max(T) detect_intra ,T detect_inter ).

[0260] Optionally, N1 is related to the DRX period. For example, the larger the DRX period, the smaller N1 is or it remains constant. Table 3 provides one possible example:

[0261] Table 3

[0262] N1 DRX cycle (ms) 4 320 2 640 1 1280 1 2560

[0263] Of course, Table 3 is just an example, and the possible values ​​of N1 are not limited to this.

[0264] Method 1 above, in T detect Within this context, measurements and evaluations of the serving cell based on MR, and searches, measurements, and evaluations of neighboring cells based on MR, do not occupy all available measurement opportunities. Therefore, there are opportunities available for measurements and evaluations of the serving cell based on LR. The larger the DRX period, the more opportunities there are for T. detect The more remaining measurement opportunities there are in internal MR measurements. In N1*T detect Within this framework, sufficient measurement opportunities (greater than the number of samples required for LR measurement) can be found for LR measurement. Method 1 facilitates simultaneous MR and LR measurements, avoiding increased latency in MR measurement and evaluation of the serving cell, as well as in searching, measuring, and evaluating neighboring cells.

[0265] Method 2: Treat the frequency points measured by LR as additional heterogeneous frequency points.

[0266] Second cycle: If the first measurement resource is SSB, then the second cycle = N2 SSB *L*DRX cycle; if the first measurement resource is LP-SS, then the second cycle is N2. LP-SS The period is *L*LP-SS. Where L=m+n, N2 SSB and N2 LP-SS L represents the number of samples required to evaluate the serving cell based on LR, where L is a positive integer and N² is the number of samples required. SSB and N2 LP-SS Let m be a positive integer and n be a positive integer.

[0267] The sixth period: determined by m+n. For example, the search period T in the sixth period. detect_inter =N detect_inter *(m+n)*DRX period, measurement period T measure_inter =N measure_inter *(m+n)*DRX period, evaluation period T evaluate_inter =N evaluate_inter *(m+n)*DRX period. N measure_inter N measure_inter and N evaluate_inter This is the number of samples required for MR searching, measuring, and evaluating inter-frequency neighboring cells. When LR measurements are not required, the search period T in the sixth cycle is... detect_inter =N detect_inter *m*DRX period, measurement period T measure_inter =N measure_inter *m*DRX period, evaluation period T evaluate_inter =N evaluate_inter*m*DRX period.

[0268] Where m is the number of inter-frequency points configured by the network for searching, measuring, and evaluating neighboring cells based on MR.

[0269] Method 2 above adds n inter-frequency points to the network based on the m number of inter-frequency points configured for MR-based search, measurement, and evaluation of neighboring cells. This increases the period for MR-based search, measurement, and evaluation of inter-frequency neighboring cells, thus ensuring that there are opportunities available for LR-based measurement and evaluation of the serving cell within the MR search, measurement, and evaluation period (i.e., the extra opportunities brought by the added n inter-frequency points). This helps to achieve simultaneous MR and LR measurements, avoids increasing the latency of MR measurement and evaluation of the serving cell, and minimizes the impact of LR measurement on MR measurement.

[0270] Method 3: Increase the latency of at least one of the following three items: search, measurement and evaluation of inter-frequency neighboring cells based on MR, search, measurement and evaluation of co-frequency neighboring cells based on MR, and measurement and evaluation of the serving cell based on MR.

[0271] The third cycle = N4 * N5 * DRX cycle. Where N4 is the number of sample points required for MR measurement and evaluation of the serving cell, and N4 and N5 are positive integers.

[0272] The fifth cycle = N6 * N7 * DRX cycle. Where N6 is the number of samples required for MR search, measurement and evaluation of co-frequency neighboring cells, and N6 and N7 are positive integers.

[0273] The sixth cycle = N8 * N9 * DRX cycle. Where N8 is the number of samples required for MR search, measurement and evaluation of inter-frequency neighboring cells, and N8 and N9 are positive integers.

[0274] Above, at least one of N5, N7, and N9 is greater than 1.

[0275] It is understandable that when N5 > 1, the latency of measuring and evaluating the serving cell based on MR increases compared to when there is no LR measurement. The latency of measuring and evaluating the serving cell based on MR becomes N5 times the original, or it can be said to be relaxed by N5 times.

[0276] When N7 > 1, the latency for searching, measuring, and evaluating co-frequency neighboring cells based on MR increases compared to when LR measurements are not performed. The latency for searching, measuring, and evaluating co-frequency neighboring cells based on MR becomes N7 times the original latency, or it can be described as a relaxation of N7 times.

[0277] When N9 > 1, the latency for searching, measuring, and evaluating inter-frequency neighboring cells based on MR increases compared to when LR measurements are not performed. The latency for searching, measuring, and evaluating inter-frequency neighboring cells based on MR becomes N9 times the original latency, or it can be described as a relaxation of N9 times.

[0278] In this case, the second cycle: if the first measurement resource is SSB, then the second cycle is N2. SSB *N3*DRX cycle; if the first measurement resource is LP-SS, then the second cycle is N2. LP-SS *N3*LP-SS cycle; where N2 SSB and N2 LP-SS To determine the number of sample points required for evaluating the serving cell based on LR, N2 SSB and N2 LP-SS N is a positive integer, and N3 is a positive integer.

[0279] See Figure 10A Taking LR measurement of SSB with a DRX period of 320ms as an example: Based on MR, the search, measurement, and evaluation of inter-frequency neighboring cells are relaxed by 2 times; based on MR, the search, measurement, and evaluation of co-frequency neighboring cells are not relaxed; based on LR, the measurement and evaluation of the serving cell are relaxed by 2 times. Within 640ms, both LR and MR have measurement opportunities.

[0280] See Figure 10B Taking LR measurement of LP-SS with a DRX period of 320ms and an LP-SS period of 320ms as an example: Based on MR, the search, measurement, and evaluation of inter-frequency neighboring cells are relaxed by 2 times; based on MR, the search, measurement, and evaluation of co-frequency neighboring cells are relaxed by 2 times; based on LR, the measurement and evaluation of the serving cell are not relaxed. Within 640ms, both LR and MR have measurement opportunities.

[0281] Method 3 above, which involves searching, measuring, and evaluating inter-frequency neighboring cells based on MR, searching, measuring, and evaluating co-frequency neighboring cells based on MR, and measuring and evaluating the serving cell based on MR, has an increased latency in at least one of the above three items. This can ensure that within the increased period, there is an opportunity to measure and evaluate the serving cell based on LR, thus enabling simultaneous MR and LR measurements.

[0282] The above clarifies the scheme for simultaneous LR and MR measurements, which avoids conflicts between the timing of LR and MR measurements. The terminal device can clearly determine how long it needs to complete LR and MR measurements, which can reduce the latency of the terminal device ending the legacy state and entering LP-WUR monitoring, case 1 or case 3 states, and improve the communication performance of the terminal device.

[0283] In one possible design, S302 above is executed when at least one of the following conditions is met:

[0284] 1) The third condition includes: the measurement results of MR on the serving cell meet the MR threshold in the entry condition of the first state, wherein the first state includes at least one of LP-WUS monitoring, complete offloading of RRM measurement, or RRM measurement relaxation.

[0285] 2) The fourth condition includes: the first measurement resource includes LP-SS, the same-frequency SMTC and the different-frequency SMTC have time conflicts, and the SMTC and LP-SS have time conflicts;

[0286] It is understandable that in this article, phrases like "resource A and resource B conflict in time" mean: the time distance between the ending point of resource A's occasion and the starting point of the next resource B's occasion is less than X; and / or, the time distance between the ending point of resource B's occasion and the starting point of the next resource A's occasion is less than X, where X is greater than or equal to 0. For example, Figure 11 Here's an example diagram illustrating a time conflict between SMTC and LP-SS: The time distance between the end point of the SMTC timing and the start point of the next LP-SS timing is less than X; or, the time distance between the end point of the LP-SS timing and the start point of the next SMTC timing is less than X, where X ≥ 0, for example, X = 1ms or X = 4ms. For time conflicts of other resources, please refer to this explanation; they will not be elaborated upon further.

[0287] Optionally, the fourth condition also includes: DRX period = 2T, same-frequency SMTC period = different-frequency SMTC period = T, LP-SS period = 2T; T is a positive integer. For example, DRX period = 320ms, same-frequency SMTC period = different-frequency SMTC period = 160ms, LP-SS period = 320ms.

[0288] 3) The fifth condition includes: the first measurement resource includes SSB, and there is a time conflict between the same frequency SMTC and the different frequency SMTC.

[0289] Optionally, the fifth condition also includes: DRX period = 2T, same-frequency SMTC period = different-frequency SMTC period = T, SSB period = T; T is a positive integer. For example, DRX period = 320ms, same-frequency SMTC period = different-frequency SMTC period = 160ms, SSB period = 160ms.

[0290] The above design approach enables LR and MR measurements to be performed only when necessary (e.g., when the MR measurement result meets the MR threshold in the entry condition of the first state) or when there is a conflict between LR and MR measurements. This avoids the reduction in measurement performance caused by using the above-described periodic configuration method when LR measurement is not necessary or when there is no conflict between LR and MR measurements.

[0291] It is understandable that the solution described above avoids the measurement timing conflict between LR and MR by configuring the second, third and fourth cycles, but the actual solution is not limited to this.

[0292] One possible alternative is:

[0293] In scenarios where the LR supports receiving orthogonal frequency division multiplexing (OFDM) signals, if the first measurement resource includes LP-SS and SSB, then: when the fourth condition is met, based on the first, second, and third configuration information, within the second period, measurement and evaluation of the serving cell based on the SSB are performed; or, when the fifth condition is met, based on the first, second, and third configuration information, within the second period, measurement and evaluation of the serving cell based on the LR are performed based on the LP-SS. The fourth and fifth conditions can be found above.

[0294] In other words, if LR measuring SSB causes a conflict in the timing of LR and MR measurements, then LR measures LP-SS; if LR measuring LP-SS causes a conflict in the timing of LR and MR measurements, then LR measures SSB.

[0295] This method selects a reference signal that does not conflict with the timing of MR measurement for LR measurement, thus avoiding a decrease in measurement performance.

[0296] It is understandable that the above implementation methods can be implemented individually or in combination.

[0297] To better understand the above solution, another example is provided below. (See...) Figure 12 This includes the following steps S401 to S406:

[0298] S401. Determine that the terminal device is in legacy state and that the network is configured with the LR threshold.

[0299] The network is configured with an LR threshold, for example: the network is configured to include an LR threshold in the entry conditions of at least one of the states of LP-WUS monitoring, Case 1, and / or Case 3.

[0300] S402. Determine whether the preset conditions are met. If they are met, execute S403; otherwise, execute S404.

[0301] For example, if at least one of the following conditions 1 to 3 is met, then S403 is executed; otherwise, S404 is executed.

[0302] Condition 1: The MR measurement results meet the MR thresholds included in the LP-WUS monitoring, Case 1 and / or Case 3 entry conditions of the network configuration.

[0303] Condition 2: LR measures LP-SS, DRX period = 320ms, same-frequency SMTC period = different-frequency SMTC period = 160ms, the offset of the same-frequency SMTC period and the different-frequency SMTC period is the same, LP-SS period = 320ms, there is a time conflict between SMTC and LP-SS.

[0304] Condition 3: LR measures SSB, DRX period = 320ms, same-frequency SMTC period = different-frequency SMTC period = 160ms, the offset of same-frequency SMTC period and different-frequency SMTC period is the same, SSB period = 160ms.

[0305] It is understandable that S402 is an optional step, and in practice, S403 can be executed by default.

[0306] S403. Perform LR measurement and / or MR measurement according to the first method.

[0307] The first method is, for example, any one of the methods 1 to 3 mentioned above.

[0308] S404. Perform LR and / or MR measurements according to the second method.

[0309] The second method differs from the first method.

[0310] For example, the period (i.e., the second period) for measuring and evaluating the serving cell based on LR is N2. SSB *DRX cycle (if LR measures SSB) or N2 LP-SS *LP-SS period (if LR measures LP-SS), N2 is the number of samples required for the measurement and evaluation of the serving cell based on LR, and N2 can be a positive integer predefined by the protocol.

[0311] For example, the period (i.e. the third period) for measuring and evaluating the serving cell based on MR is N4*DRX period, where N4 is the number of samples required for measuring and evaluating the serving cell based on MR.

[0312] For example, the period (i.e. the fifth period) for searching, measuring and evaluating co-frequency neighboring cells based on MR is N6*DRX period, where N6 is the number of samples required for searching, measuring and evaluating co-frequency neighboring cells based on MR.

[0313] For example, the period (i.e. the sixth period) for measuring and evaluating inter-frequency neighboring cells based on MR is N8*DRX period, where N8 is the number of samples required for searching, measuring and evaluating inter-frequency neighboring cells based on MR.

[0314] The above example clarifies the measurement behavior of LR and MR when the terminal device is in legacy state and the entry conditions for LR measurement are met, thus avoiding LR and MR from being measured at the same time and minimizing the impact of LR measurement on MR measurement.
