Description

Communication method, device and computer-readable storage medium

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on February 8, 2024, with application number 202410176977.2 and application name “A communication method, device and computer-readable storage medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method, device, and computer-readable storage medium. Background Art

[0003] Measurement is a crucial process for mobile devices. It's a prerequisite for mobility. By measuring the signal quality of the serving cell and neighboring cells, mobile devices can determine whether to reselect to a neighboring cell. Mobile devices must perform effective measurements in the Radio Resource Control (RRC) IDLE (RRC_IDLE) state, the RRC Connected (RRC_CONNECTED) state, and the RRC Inactive (RRC_INACTIVE) state. These measurements consume significant power. Summary of the Invention

[0004] The present application discloses a communication method, device and computer-readable storage medium, which are conducive to saving power consumption.

[0005] In a first aspect, the present application provides a communication method, which can be applied to a terminal device, or to a device in the terminal device (e.g., a chip, or a chip system, or a circuit), or a device that can be used with the terminal device. The following description is given using the application to the terminal device as an example. The method may include: receiving an LPWUS, the LPWUS including first indication information, the first indication information indicating a measurement skipping condition for at least one measurement time period within a CDRX cycle, the at least one measurement time period including a first measurement time period, the measurement skipping condition for the first measurement time period including skipping measurement; and skipping measurement in the first measurement time period.

[0006] In this technical solution, the first indication information is used to instruct the terminal device to skip measurement in at least one measurement time period (such as the first measurement time period), that is, not to perform measurement, which can reduce the power consumption of the terminal device.

[0007] In one implementation, one measurement time period of the at least one measurement time period includes an SMTC window and / or a measurement gap.

[0008] In one implementation, the first indication information is carried by the first bit, wherein, when the value of the first bit is a first value, the first indication information indicates that the measurement skipping situation for all or part of the measurement time periods in the at least one measurement time period is skip measurement; when the value of the first bit is a second value, the first indication information indicates that the measurement skipping situation for all measurement time periods in the at least one measurement time period is execution measurement.

[0009] In an implementation manner, the LPWUS further includes second indication information, where the second indication information indicates a measurement skipping condition for each measurement time period in the at least one measurement time period.

[0010] In this technical solution, the second indication information indicates which specific measurement time period or time periods within the CDRX cycle need to skip measurement. Furthermore, the terminal device can skip measurement during these measurement time periods, which can save power consumption. Optionally, these measurement time periods can be used to transmit scheduling information. The terminal device can monitor the scheduling information during these measurement time periods. When the scheduling information is monitored and received, the terminal device transmits uplink and downlink channels or uplink and downlink signals based on the scheduling information. This is conducive to improving system capacity, thereby facilitating the support of more terminal devices to transmit multimedia service data (such as XR service data) in multimedia service scenarios.

[0011] In one implementation, the second indication information includes an index of a first measurement pattern in a first measurement pattern set, each measurement pattern in the first measurement pattern set is used to indicate a measurement skipping condition for each measurement time period in the at least one measurement time period, and the second indication information indicates the measurement skipping condition for each measurement time period in the at least one measurement time period through the first measurement pattern.

[0012] In one implementation, the LPWUS further includes third indication information, where the third indication information indicates a measurement skipping condition for a first time within a first measurement time period, where a unit of the first time includes one or more of milliseconds, time slots, or symbols.

[0013] In this technical solution, the third indication information indicates which specific milliseconds (time slots or symbols) need to skip measurement, which can save power consumption.

[0014] In one implementation, the third indication information includes one or more of the following: an index of a second measurement pattern, an index of a third measurement pattern, and an index of a fourth measurement pattern, where the second measurement pattern is a measurement pattern in a second measurement pattern set, the third measurement pattern is a measurement pattern in a third measurement pattern set, and the fourth measurement pattern is a measurement pattern in a fourth measurement pattern set; wherein each measurement pattern in the second measurement pattern set is used to indicate a measurement skipping condition for each half millisecond or each millisecond in a first measurement time period, each measurement pattern in the third measurement pattern set is used to indicate a measurement skipping condition for each time slot in the first measurement time period, and each measurement pattern in the fourth measurement pattern set is used to indicate a measurement skipping condition for each symbol in the first time slot. The third indication information indicates the measurement skipping condition for the first time through one or more of the second measurement pattern, the third measurement pattern, and the fourth measurement pattern.

[0015] In one implementation, the first measurement time period includes at least one time unit corresponding to an SSB, and the LPWUS also includes fourth indication information, the fourth indication information indicates a measurement skipping situation for the time unit corresponding to the at least one SSB, the at least one SSB includes a first SSB, and the measurement skipping situation for the time unit corresponding to the first SSB includes: skipping measurement for the first SSB within the time unit corresponding to the first SSB.

[0016] In this technical solution, the fourth indication information indicates which specific SSB or SSBs need to skip measurement in the corresponding time unit, which can save power consumption.

[0017] In one implementation, the fourth indication information includes an index of a fifth measurement pattern in a fifth measurement pattern set, and each measurement pattern in the fifth measurement pattern set is used to indicate a measurement skipping condition for a time unit corresponding to each SSB in the at least one SSB. The fourth indication information indicates a measurement skipping condition for a time unit corresponding to each SSB in the at least one SSB through the fifth measurement pattern.

[0018] In one implementation, the method further includes: receiving configuration information, where the configuration information is used to configure the first measurement pattern set.

[0019] In one implementation, the method further includes: sending fifth indication information, where the fifth indication information is used to indicate that it is desired to skip measurement in one or more measurement time periods in the CDRX cycle.

[0020] In one implementation, the fifth indication information is carried in the UAI.

[0021] In a second aspect, the present application provides a communication method, which can be applied to an access network device, or to a device in the access network device (for example, a chip, or a chip system, or a circuit), or a device that can be used in conjunction with the access network device.

[0022] In this technical solution, the first indication information is used to instruct the terminal device to skip measurement in at least one measurement time period (such as the first measurement time period), so the access network device may not send SSB in the first measurement time period, which is conducive to reducing power consumption.

[0023] In one implementation, one measurement time period of the at least one measurement time period includes an SMTC window and / or a measurement gap.

[0024] In one implementation, the first indication information is carried by the first bit, wherein, when the value of the first bit is a first value, the first indication information indicates that the measurement skipping situation for all or part of the measurement time periods in the at least one measurement time period is skip measurement; when the value of the first bit is a second value, the first indication information indicates that the measurement skipping situation for all measurement time periods in the at least one measurement time period is execution measurement.

[0026] In this technical solution, the second indication information indicates which measurement time periods within the CDRX cycle should be skipped. Furthermore, the access network device can avoid sending SSBs during these measurement time periods, thereby saving power. Optionally, these measurement time periods can be used to transmit scheduling information, which helps improve system capacity.

[0055] The specific embodiments of the present application are further described in detail below with reference to the accompanying drawings.

[0056] The terms "first" and "second" and the like in the specification, claims, and drawings of this application are used to distinguish between different objects, not to describe a particular order. Furthermore, the terms "including" and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements, but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0057] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0058] In this application, "at least one (item)" refers to one or more, "more than one" refers to two or more, "at least two (items)" refers to two or three and more than three, and "and / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where each of a, b, c can be an element or a set containing one or more elements.

[0059] In this application, "sending information to... (e.g., a terminal device)" can be understood as the destination of the information being the terminal device. This can include sending information to the terminal device directly or indirectly. "Receiving information from... (e.g., a terminal device)" or "receiving information from... (e.g., a terminal device)" can be understood as the source of the information being the terminal device, which can include receiving information from the terminal device directly or indirectly. The information may be processed as necessary between the source and destination of the information, such as format changes, but the destination can understand the valid information from the source. Similar expressions in this application can be understood similarly and will not be elaborated on here.

[0060] In the description of this application, "indication" may include direct indication and indirect indication, and may also include explicit indication and implicit indication. The information indicated by a certain information (such as the indication information described below) is called information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated. For example, the information to be indicated can be directly indicated, such as indicating the information to be indicated itself or the index of the information to be indicated. For another example, the information to be indicated can also be indirectly indicated by indicating other information, and there is an association between the other indicated information and the information to be indicated. For another example, only a part of the information to be indicated can be indicated, while the other parts of the information to be indicated are known or agreed in advance. In addition, the indication of specific information can be achieved by means of the pre-agreed (such as specified in the protocol) order of arrangement of each information, thereby reducing the indication overhead to a certain extent.

[0061] To better understand the embodiments of the present application, the following first introduces the system architecture involved in the embodiments of the present application:

[0062] The embodiments of the present application can be applied to communication systems evolved after 5G, such as long term evolution (LTE) systems, fifth generation mobile communication (5G) systems, sixth generation mobile communication (6G) systems, satellite communications, and short-range wireless communication systems. Among them, the wireless communication systems mentioned in the embodiments of the present application include but are not limited to: three major application scenarios of 5G / 6G mobile communication systems: enhanced mobile broadband (eMBB), ultra reliable low latency communication (URLLC) and massive machine type communication (mMTC), long range Internet of Things (LoRa) systems or vehicle networking systems. The wireless communication system may include one or more access network devices, and one or more terminal devices.

[0063] The following explanation uses the system architecture shown in Figure 1 as an example. As shown in Figure 1, communication system 1000 includes a radio access network (RAN) 100 and a core network (CN) 200. RAN 100 includes at least one access network device (e.g., 110a and 110b in Figure 1, collectively referred to as 110) and at least one terminal device (e.g., 120a-120j in Figure 1, collectively referred to as 120). RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1). Terminal device 120 is wirelessly connected to access network device 110. Access network device 110 is wirelessly or wiredly connected to core network 200. The core network devices in core network 200 and access network device 110 in RAN 100 can be separate physical devices, or they can be a single physical device that integrates core network logical functions and radio access network logical functions.

[0064] It should be noted that RAN 100 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), for example, a 4G or 5G mobile communication system, or an evolved system after 5G (for example, a 6G mobile communication system). RAN 100 can also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (CRAN), etc. RAN 100 can also be a communication system that is a fusion of two or more of the above systems. It should be stated that the number of access network devices and terminal devices in Figure 1 is only for illustration and should not be regarded as a specific limitation on the present application. The terminal devices and access network devices involved in the system architecture are described in detail below.

[0065] 1. Terminal Equipment

[0066] Terminal devices can also be called user equipment (UE), mobile station (MS), mobile terminal (MT), etc. They are devices used to provide voice or data connectivity to users, or they can be IoT devices. For example, terminal devices include handheld devices with wireless connectivity, in-vehicle devices, etc. At present, terminal devices can be: mobile phones, tablet computers, laptops, PDAs, mobile internet devices (MIDs), wearable devices, vehicle-mounted devices (e.g., cars, bicycles, electric vehicles, airplanes, ships, trains, high-speed railways, etc.), satellite terminals, virtual reality (VR) devices, augmented reality (AR) devices, smart point of sale (POS) machines, customer-premises equipment (CPE), wireless terminals in industrial control, smart home devices (e.g., refrigerators, TVs, air conditioners, electric meters, etc.), intelligent robots, robotic arms, workshop equipment, wireless terminals in unmanned driving, wireless terminals in telemedicine, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, or wireless terminals in smart homes, flight equipment (e.g., intelligent robots, hot air balloons, drones, airplanes), etc. The terminal device can also be other devices with terminal functions, for example, the terminal device can also be a device that serves as a terminal function in D2D communication. The terminal device in the application embodiment can also be a terminal device that supports a power saving function.

[0067] As an example and not a limitation, the wearable devices in the embodiments of the present application may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for everyday wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not just hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0068] The embodiments of this application do not limit the device form factor of the terminal device. The device used to implement the functions of the terminal device can be the terminal device; it can also be a device that supports the terminal device to implement the functions, such as a chip system. The device can be installed in the terminal device or used in conjunction with the terminal device. In the embodiments of this application, the chip system can be composed of a chip or include a chip and other discrete components.

[0069] 2. Access Network Equipment

[0070] An access network device is a node in a radio access network (RAN), and can also be referred to as a network device or a RAN node (or device). An access network device is used to help terminal devices achieve wireless access. The multiple access network devices 110 in the communication system 1000 can be nodes of the same type or different types. In some scenarios, the roles of the access network device 110 and the terminal device 120 are relative. For example, the network element 120i in Figure 1 can be a helicopter or a drone, which can be configured as a mobile base station. For terminal devices 120j that access the RAN 100 through the network element 120i, the network element 120i is a base station; but for the base station 110a, the network element 120i is a terminal device. The access network device 110 and the terminal device 120 are sometimes referred to as communication devices. For example, the network elements 110a and 110b in Figure 1 can be understood as communication devices with base station functions, and the network elements 120a-120j can be understood as communication devices with terminal functions.

[0071] In one possible scenario, an access network device can be a base station, an evolved NodeB (eNodeB), a transmitting and receiving point (TRP), a transmitting point (TP), a next-generation NodeB (gNB), a next-generation base station in a sixth-generation (6G) mobile communication system, a base station in a future mobile communication system, a satellite, an integrated access and backhaul (IAB) node, a mobile switching center, or an access network device in a non-terrestrial network (NTN) communication system, i.e., it can be deployed on a high-altitude platform or satellite. The access network device can be a macro base station (such as 110a in Figure 1), a micro base station or an indoor station (such as 110b in Figure 1), a relay node or a donor node, or a wireless controller in a CRAN scenario. The access network device can also function as a base station in device-to-device (D2D) communication, vehicle-to-vehicle communication, drone communication, or machine communication. Optionally, the access network device may also be a server, a wearable device, a vehicle or an onboard device, etc. For example, the access network device in vehicle to everything (V2X) technology may be a road side unit (RSU).

[0072] All or part of the functions of the access network device in this application may also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform). The access network device in this application may also be a logical node, logical module, or software that can implement all or part of the functions of the access network device.

[0073] In another possible scenario, multiple access network devices collaborate to assist terminal devices in achieving wireless access, and different access network devices respectively implement part of the functions of the base station. For example, the access network device can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or they can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). It can be understood that the access network device can be a CU node, a DU node, or a device including a CU node and a DU node. In addition, the CU can be divided into an access network device in the access network RAN, or the CU can be divided into an access network device in the core network CN, which is not limited here.

[0074] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0075] In the embodiments of the present application, the form of the access network device is not limited. The device used to implement the functions of the access network device can be the access network device; it can also be a device that supports the access network device to implement the functions, such as a chip system. The device can be installed in the access network device or used in conjunction with the access network device.

[0076] In order to facilitate understanding of the contents of this solution, some concepts or technologies involved in the embodiments of this application are explained below to facilitate understanding by those skilled in the art. This part is only for ease of understanding and cannot be regarded as a specific limitation of this application.

[0077] (1) XR business

[0078] Real-time broadband communication (RTBC) in future communication systems aims to support high bandwidth and low interaction latency. This allows for increased bandwidth within given latency and reliability requirements, creating an immersive experience for users interacting with the virtual world. XR technology is a technology that enables the interaction between virtual and real life, encompassing virtual reality (VR), augmented reality (AR), and mixed reality (MR). VR, AR, and MR are collectively referred to as XR. XR services refer to those based on XR technology.

[0079] During the downlink transmission of XR services, the server's XR content module generates data content at a fixed frequency (e.g., 30Hz, 60Hz, 120Hz, etc.) and transmits it to the XR terminal device through the network device. During the uplink transmission of XR services, devices such as AR terminal devices or MR terminal devices can capture the current scene image through the built-in camera and continuously upload the current scene image at a specific frequency (e.g., 60Hz).

[0080] XR services are primarily video services, and video data is generated in bursts, meaning that data for the same service is generated periodically. For example, if 1 second (s) contains 60 frames of video data, then a video frame is generated every 16.6 milliseconds (ms). Because the data size of a video frame is so large, it is split into dozens of Internet Protocol (IP) packets. In other words, XR data is large.

[0081] For networks transmitting XR services, dozens of IP packets must be transmitted every 16.6ms, and the arrival time of these IP packets is uncertain. The difference between the arrival time of an IP packet and a periodic time point (e.g., 0ms, 16.6ms, 33.2ms, etc.) is roughly in the range of [-4, 4]ms or [-5, 5]ms, and follows a truncated Gaussian distribution. This range of [-4, 4]ms or [-5, 5]ms can be considered jitter.

[0082] (2) Measurement

[0083] Measurement is a crucial process in mobile communication systems. By measuring the signal quality of the serving cell and neighboring cells, a terminal device can determine whether to reselect to a neighboring cell. Measurements can be categorized as intra-frequency and inter-frequency.

[0084] Co-frequency measurement means that the frequency points of the terminal device's serving cell and the frequency points of the neighboring cell are on the same carrier frequency point. For example, if the frequency points of the terminal device's serving cell and the neighboring cell are both on the same frequency point within the FR2 frequency band, the terminal device can perform co-frequency measurement. Among them, the 5G frequency band is divided into FR1 and FR2. Among them, the operating frequency range of the FR1 band is 450MHz to 6GHz, and it is widely used for mobile communications in urban and rural areas. The operating frequency range of the FR2 band is 24.25GHz to 52.6GHz, and it is mainly used in high-speed mobile communications and indoor coverage scenarios.

[0085] Inter-frequency measurement means that the frequency of the terminal device's serving cell and the frequency of the neighboring cell are not on the same carrier frequency.

[0086] (3) Measurement gap

[0087] Currently, network equipment can configure neighboring cell measurement methods for terminal devices based on their capabilities, such as inter-frequency and inter-system measurement control tasks. These methods can be broadly categorized into two types: Cell Measurement Method 1: Neighboring cell measurement based on gaps (measurement gaps). Within the measurement gap, the terminal device interrupts data transmission and reception with the serving cell to perform neighboring cell measurements. Cell Measurement Method 2: Neighboring cell measurement based on no gaps (no gaps), i.e., measurements not based on measurement gaps.

[0088] The measurement gap can be understood as a period of time reserved for the terminal device to receive signals from neighboring cells and complete measurements. During the measurement gap, the original serving cell does not schedule uplink and downlink transmissions. When the measurement gap ends, the terminal device resumes communication with the original serving cell.

[0089] Measuring GAP can be used to perform inter-frequency measurements and inter-system measurements. Inter-system measurements refer to when the terminal device's serving cell and neighboring cell are cells in different systems. In other words, the terminal device's serving cell and neighboring cell belong to cells of different standard systems, for example, the serving cell is an NR cell and the neighboring cell is an LTE cell.

[0090] It should be noted that when the frequency of the serving cell and the frequency of the neighboring cell are at the same carrier frequency (i.e., in the same-frequency measurement scenario), but the subcarrier spacing (SCS) of the serving cell is different from that of the neighboring cell, the terminal device also needs to complete the neighboring cell measurement based on the measurement GAP.

[0091] The parameters for measuring GAP configured by the network device for the terminal device may include but are not limited to: the duration of measuring GAP, the period of measuring GAP, etc.

[0092] The terminal device can determine the system frame and subframe for measuring GAP based on the following formula:

[0093] SFN mod T=FLOOR(gapOffset / 10)

[0094] subframe=gapOffset mod 10

[0095] T=MGRP / 10

[0096] SFN represents the system frame; subframe represents the subframe; MGRP represents the period for measuring the GAP; gapOffset represents the offset value of the GAP mode, which can be configured in the GapConfig information element; FLOOR represents rounding down; and mod represents the modulo operation.

[0097] (4) Synchronization Signal / PBCH Block (SSB)

[0098] The SSB consists of primary synchronization signals (PSS), secondary synchronization signals (SSS) and physical downlink broadcast channel (PBCH).

[0099] The number of SSBs varies across frequency bands. For example, for sub-3G, frequency division duplexing (FDD) and time division duplexing (TDD) below 2.4G, a maximum of 4 SSBs are defined, while for TDD above 2.4G, a maximum of 8 SSBs are defined. For sub-3G to sub-6G, a maximum of 8 SSBs are defined, and for sub-6G and above, a maximum of 64 SSBs are defined.

[0100] In the time domain, one SSB occupies 4 orthogonal frequency-division multiplexing (OFDM) symbols; in the frequency domain, one SSB occupies 20 consecutive physical resource blocks (PRBs). The symbols and PRBs occupied by the specific PSS, SSS, and PBCH are not limited in the embodiments of the present application. In the time domain, within half a frame (i.e., 5ms), the number and position of SSBs are determined according to the subcarrier spacing and frequency band; multiple SSBs within a half frame form an SS burst set. The SS burst set includes the SSBs required to complete a beam scan. An SSB in an SS burst set corresponds to a beam scan direction, or in other words, an SSB in an SS burst set corresponds to a beam. The SS burst set is sent at a certain period.

[0101] Among them, for the SSB included in the half-frame, the index of the first symbol of each SSB can be determined according to the sub-carrier space (SCS) of the SSB, as shown below:

[0102] Case A: 15 kHz SCS, the index of the first symbol of each SSB is {2, 8} + 14·n. For operation without shared spectrum channel access: for carrier frequencies less than or equal to 3 GHz, n = 0, 1; for carrier frequencies within FR1 greater than 3 GHz, n = 0, 1, 2, 3. For operation with shared spectrum channel access: n = 0, 1, 2, 3, 4.

[0103] Case B: 30 kHz SCS, the index of the first symbol of each SSB is {4, 8, 16, 20} + 28·n. For carrier frequencies less than or equal to 3 GHz, n = 0; for carrier frequencies greater than 3 GHz within FR1, n = 0, 1.

[0104] Case C: 30 kHz SCS, the index of the first symbol of each SSB is {2, 8} + 14·n. For operation without shared spectrum channel access: For paired spectrum operation, for carrier frequencies less than or equal to 3 GHz, n = 0, 1; for carrier frequencies within FR1 greater than 3 GHz, n = 0, 1, 2, 3. For unpaired spectrum operation, for carrier frequencies less than 1.88 GHz, n = 0, 1; for carrier frequencies within FR1 greater than or equal to 1.88 GHz, n = 0, 1, 2, 3. For operation using shared spectrum channel access: n = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

[0105] Case D: 120 kHz SCS, the index of the first symbol of each SSB is {4, 8, 16, 20} + 28·n. For carrier frequencies in FR2, n = 0, 1, 2, 3, 5, 6, 7, 8, 10, 11, 12, 13, 15, 16, 17, 18.

[0106] Case E: 240 kHz SCS, the index of the first symbol of each SSB is {8, 12, 16, 20, 32, 36, 40, 44} + 56·n. For carrier frequencies within FR2-1, n = 0, 1, 2, 3, 5, 6, 7, 8.

[0107] Case F: 480 kHz SCS, the index of the first symbol of the candidate SS / PBCH block is {2, 9} + 14·n. For carrier frequencies in FR2-2, n = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31.

[0108] For example, based on Case A, 15KHz SCS, for a carrier frequency less than or equal to 3GHz without shared spectrum channel access, when n=0, the indices of the first symbols of the two SSBs in a time slot are 2 and 8 respectively; when n=1, the indices of the first symbols of the two SSBs in a time slot are 16 and 22 respectively.

[0109] (5)SMTC window

[0110] To avoid unnecessary measurements and reduce power consumption in terminal devices, an SSB-based measurement timing configuration (SMTC) window can be defined in the SS burst set. Network devices use the SMTC window to inform terminal devices of the measurement period and timing for SSB measurements. In other words, SMTC is a window configured by the network for terminal devices to perform SSB measurements. Terminal devices only need to perform SSB measurements within the SMTC window and do not need to perform SSB measurements outside the SMTC window. The SMTC period and offset can be configured based on the SSB period and offset. Terminal devices measure NR SSBs based on the SMTC window configured on the network side and can configure SMTCs for SSBs at different frequencies. For connected intra-frequency measurements, the network can configure up to two SMTC windows for terminal devices on a single frequency. For connected inter-frequency measurements, the network can configure up to one SMTC window for each frequency. The configuration parameters of an SMTC window include: SMTC timing: The period and offset information of the SMTC window. The SMTC period can be 5, 10, 20, 40, 80, or 160 ms. SMTC duration: The length of the SMTC window. The granularity of the SMTC window length is also 1 ms, and the length can be 1, 2, 3, 4, or 5 meters.

[0111] For example, see Figure 2, a schematic diagram of sending an SSB in an SMTC window. Figure 2 takes an SS burst set period of 20 milliseconds (ms), an SS burst set including an SMTC window of 5 ms, and a subcarrier spacing of 30 kHz in the cell sending the SSB as an example. When the subcarrier spacing is 30 kHz, the time slot length is 0.5 ms. Therefore, an SMTC window may include 10 time slots. One time slot includes 14 orthogonal frequency-division multiplexing (OFDM) symbols.

[0112] In Figure 2, the frequency point of the cell sending SSB belongs to the Sub3G~Sub6G frequency band as an example. Therefore, the cell can send up to 8 SSBs in the SMTC window. The cell can send a total of 8 SSBs in 4 time slots (such as time slot 0 to time slot 3) in the SMTC window. 2 SSBs are sent in each of the 4 time slots. One SSB occupies 4 OFDM symbols. The specific symbols and resource blocks (RBs) occupied by PSS, SSS and PBCH are not limited in the embodiment of this application.

[0113] In another example, if the subcarrier spacing of the cell transmitting SSBs in Figure 2 is 120 kHz, then the time slot length is 0.125 ms, and an SMTC window can include 40 time slots. If the frequency point of the cell belongs to the Sub6G frequency band or above, then the cell can send a maximum of 64 SSBs in the SMTC window. The cell can send a total of 64 SSBs in 32 time slots within the SMTC window, with 2 SSBs in each time slot.

[0114] It can be understood that when the terminal device measures the serving cell, it specifically measures the SSB from the serving cell within the SMTC window. In this case, the SSB shown in Figure 2 is the SSB sent by the serving cell.

[0115] When the terminal device measures the neighboring cell, it specifically measures the SSB from the neighboring cell within the SMTC window.

[0116] If the frequency point of the neighboring cell is not in the same carrier frequency point as the frequency point of the serving cell, and / or the subcarrier spacing of the neighboring cell is different from the subcarrier spacing of the serving cell, the terminal device needs to measure the SSB from the neighboring cell within the SMTC window within the measurement GAP.

[0117] For example, the relationship between the measurement GAP and the SMTC window can be seen in Figure 3. Figure 3 takes the measurement GAP duration as 6ms as an example. The SMTC window in Figure 3 refers to the description of the SMTC window in Figure 2. In this case, the SSB shown in Figure 2 is the SSB sent by the neighboring cell.

[0118] In one implementation, the serving cell may configure a measurement GAP for the terminal device based on the SMTC window configuration and SSB configuration of the neighboring cell, and the duration of the measurement GAP may be greater than or equal to the duration of the SMTC window of the neighboring cell, so that the terminal device measures the SSB sent by the neighboring cell within the measurement GAP. It should be noted that the SMTC window configuration of the neighboring cell may be the same as or different from the SMTC window configuration of the serving cell, and this is not limited in the embodiments of the present application. For example, the duration of the SMTC window of the serving cell may be the same as or different from the duration of the SMTC window of the neighboring cell.

[0119] (5) Discontinuous Reception (DRX), Connected mode DRX (CDRX)

[0120] DRX allows the terminal device to periodically enter a sleep state at certain times and not monitor the Physical Downlink Control Channel (PDCCH). When monitoring is required, the terminal device wakes up from the sleep state to monitor and receive the PDCCH.

[0121] Exemplarily, a DRX cycle is shown in Figure 4. A DRX cycle includes wake-up time and sleep time. The wake-up time refers to the period during which the On DurationTimer (On DurationTimer) is running, that is, the period during which the On DurationTimer has not timed out. During the wake-up time, the terminal device monitors and receives the PDCCH. When the On DurationTimer times out and the terminal device does not receive the PDCCH, the terminal device enters the sleep state, and the terminal device does not monitor the PDCCH during the sleep time. During the wake-up time, when the terminal device receives the PDCCH, the terminal device starts the drx inactivity timer (drx-InactivityTimer) and monitors the PDCCH while the drx-InactivityTimer is running. Optionally, when the drx-InactivityTimer times out, the terminal device can enter the sleep state.

[0122] CDRX configures the DRX cycle for terminal devices in connected state.

[0123] It should be noted that the wake-up time may include one or more SMTC windows, and the wake-up time may include one or more measurement GAPs.

[0124] (6) Low Power Wake Up Signal (LP WUS)

[0125] In order to reduce the power consumption of terminal equipment, the 3rd Generation Partnership Project (3GPP) introduced LPWUS.

[0126] The terminal device may include a main receiver (Main Receiver) and a low power wake-up receiver (Low power wake-up receiver). LPWUS can be used to indicate whether to wake up the main receiver. When the low power wake-up receiver is in the awake state, it can receive LPWUS and wake up or not wake up the main receiver based on LPWUS. Specifically, the schematic diagram of LPWUS for waking up the main receiver is shown in Figure 5. If the LPWUS indicates to wake up the main receiver, the low power wake-up receiver can wake up the main receiver (as shown by the dotted line in Figure 5), so that the main receiver is in the awake state. If the LPWUS indicates not to wake up the main receiver, the main receiver remains in a sleep state or a closed state. For example, the wake-up indication carried in the LPWUS is ON. In this case, the LPWUS indicates to wake up the main receiver. The wake-up indication carried in the LPWUS is OFF. In this case, the LPWUS indicates not to wake up the main receiver.

[0127] The sleep state may include but is not limited to ultra-deep sleep, deep sleep, light sleep, and micro sleep.

[0128] The above is a brief introduction to some of the concepts or technologies involved in the embodiments of this application.

[0129] Currently, energy conservation is a global trend. In order to reduce the power consumption of terminal devices, an embodiment of the present application provides a communication method in which an access network device instructs a terminal device through LPWUS to skip measurement (i.e., not perform measurement) during a measurement time period originally used for measurement, thereby saving power consumption. In one implementation, these measurement time periods originally used for measurement (such as same-frequency measurement, different-frequency measurement, and different-system measurement) can be used to transmit scheduling information. Accordingly, the terminal device can transmit uplink and downlink channels or uplink and downlink signals within these measurement time periods based on the scheduling information, thereby improving system capacity.

[0130] The communication method provided in the embodiment of the present application is described in detail below based on the system architecture shown in FIG1 .

[0131] The terminal device in the following embodiments (such as the embodiment corresponding to Figure 6 below) can be a terminal device in the network architecture shown in Figure 1, and the functions performed by the terminal device in this embodiment can also be performed by a device in the terminal device (for example, a chip, or a chip system, or a circuit). The access network device in the following embodiments can be an access network device in the network architecture shown in Figure 1, and the functions performed by the access network device in this embodiment can also be performed by a device in the access network device (for example, a chip, or a chip system, or a circuit). The embodiments of this application are uniformly explained here and will not be repeated later.

[0132] Please refer to FIG6 , which is a flowchart of a communication method provided in an embodiment of the present application. The method may include but is not limited to the following steps:

[0133] 601. An access network device sends an LPWUS, where the LPWUS includes first indication information. The first indication information indicates a measurement skipping condition for at least one measurement time period within a CDRX cycle, where the at least one measurement time period includes a first measurement time period, and the measurement skipping condition for the first measurement time period includes skipping measurement. Accordingly, the terminal device receives the LPWUS.

[0134] The first indication information indicates the measurement skipping situation for at least one measurement time period within the CDRX cycle (hereinafter referred to as Z measurement time periods, where Z is a positive integer). It can be understood that the access network device instructs the terminal device on its behavior within the Z measurement time periods through the first indication information.

[0135] Taking one measurement time period among the Z measurement time periods as an example, the behavior of the terminal device during the measurement time period may include: the terminal device skipping measurement and / or performing measurement during the measurement time period. The terminal device performing measurement during the measurement time period may mean: the terminal device measures the SSB during the measurement time period. The terminal device skipping measurement during the measurement time period may mean: the terminal device does not perform measurement during the measurement time period, that is, does not measure the SSB.

[0136] In one implementation, instructing a terminal device to skip measurement and perform measurement within a measurement time period refers to instructing the terminal device to skip measurement within a portion of the time units within the measurement time period and perform measurement within another portion of the time units. The time unit may be a frame, a subframe, a millisecond (ms), half a millisecond, a slot, a mini slot, a symbol, or a transmission time interval (TTI), etc., and the embodiments of the present application are not limited thereto.

[0137] It can be understood that instructing the terminal device to skip measurement during a measurement time period means instructing the terminal device to skip measurement during some or all time units within the measurement time period. Instructing the terminal device to perform measurement during a measurement time period means instructing the terminal device to measure the SSB during some or all time units within the measurement time period.

[0138] The Z measurement time periods may be the Z measurement time periods encountered by the terminal device within the CDRX cycle after receiving the LPWUS. The Z measurement time periods may include all or part of the measurement time periods within the CDRX cycle.

[0139] The first measurement time period refers to a measurement time period in which the measurement skipping condition is skipped measurement among the Z measurement time periods. The number of first measurement time periods may be one or more. The measurement time period in which the measurement skipping condition is performed measurement among the Z measurement time periods may be referred to as a second measurement time period. The number of second measurement time periods may be one or more.

[0140] The measurement time period in the embodiment of the present application may include an SMTC window and / or a measurement GAP. That is, the access network device may indicate the behavior of the terminal device within the Z SMTC windows and / or measurement GAPs encountered within the CDRX cycle through the first indication information. For example, the access network device may only indicate the behavior of the terminal device within the SMTC window (encountered within the CDRX cycle) through the first indication information, or only indicate the behavior of the terminal device within the measurement GAP (encountered within the CDRX cycle), or indicate the behavior of the terminal device within the SMTC window and measurement GAP (encountered within the CDRX cycle).

[0141] In one implementation, the measurement skipping situations for the Z measurement time periods indicated by the first indication information may be the same or different. Taking the Z measurement time periods including measurement time period a and measurement time period b as an example, the content indicated by the first indication information may be: instructing the terminal device to skip measurement in both measurement time period a and measurement time period b, or instructing the terminal device to perform measurement in both measurement time period a and measurement time period b, or instructing the terminal device to skip measurement in measurement time period a and instructing the terminal device to perform measurement in measurement time period b.

[0142] The measurement time period in the CDRX cycle is originally used for measurement. Specifically, the terminal device can originally measure the SSB from the serving cell within the SMTC window, and the terminal device can originally measure the SSB from the neighboring cell within the SMTC window within the measurement GAP. By adopting the communication method provided in the embodiment of the present application, the access network device can instruct the terminal device to skip measurement in at least one measurement time period (such as the first measurement time period) through the first indication information, that is, not perform measurement, thereby reducing the power consumption of the terminal device.

[0143] 602. The terminal device skips measurement in the first measurement time period.

[0144] The terminal device skipping measurement in the first measurement time period may include: the terminal device not detecting SSB or measuring SSB in some or all time units in the first measurement time period. For the access network device, SSB may not be sent in some or all time units in the first measurement time period.

[0145] In one implementation, if the terminal device does not receive the LPWUS including the first indication information, the terminal device may default to performing measurements normally in each measurement time period within the CDRX cycle.

[0146] In one implementation, in addition to indicating the measurement skipping condition for at least one measurement time period within the CDRX cycle (indicated by the LPWUS through the first indication information carried), the LPWUS may also be used to indicate whether the low-power wake-up receiver in the terminal device wakes up the main receiver. Alternatively, the LPWUS is not used to indicate whether the low-power wake-up receiver in the terminal device wakes up the main receiver.

[0147] In an embodiment of the present application, by adopting the communication method provided in an embodiment of the present application, the access network device can instruct the terminal device, through first indication information, to skip measurement in at least one measurement time period (such as the first measurement time period), that is, not perform measurement, thereby reducing power consumption of the terminal device. For the access network device, SSB may not be sent in the first measurement time period, which is conducive to reducing power consumption.

[0148] In one implementation, the first indication information can also be used to indicate that the first measurement time period is used to transmit scheduling information. Alternatively, the first indication information indicates that the measurement skipping situation for the first measurement time is skip measurement. After the terminal device receives the LPWUS, it can skip the measurement in the first measurement time period based on the LPWUS and listen to the scheduling information in the first measurement time period. The scheduling information can be carried in the PDCCH. For the access network device, scheduling information can be sent within the first measurement time period, and the scheduling information is used to schedule uplink and downlink channels or uplink and downlink signals; for the terminal device, scheduling information can be listened to within the first measurement time period. When the scheduling information is listened to and received, the uplink and downlink channels or uplink and downlink signals are transmitted (sent and / or received) based on the scheduling information.

[0149] The measurement time period in the CDRX cycle was originally used for measurement. Specifically, the terminal device could originally measure the SSB from the serving cell within the SMTC window, and since the access network device will not perform uplink scheduling or downlink scheduling on the terminal device within the SMTC window, accordingly, the terminal device does not need to monitor the scheduling information within the SMTC window, nor will it receive scheduling information. The terminal device could originally measure the SSB from the neighboring cell within the SMTC window within the measurement GAP, and since the access network device will not perform uplink scheduling or downlink scheduling on the terminal device within the measurement GAP, accordingly, the terminal device does not need to monitor the scheduling information within the measurement GAP, nor will it receive scheduling information. That is to say, before adopting the communication method provided in the embodiment of the present application, the terminal device does not monitor scheduling information within the SMTC window or the measurement GAP.

[0150] When the communication method provided in the embodiment of the present application is adopted, the first measurement time period originally used for measurement is used to transmit scheduling information, which is beneficial to improving system capacity.

[0151] Optionally, the uplink and downlink channels or uplink and downlink signals scheduled by the scheduling information can carry uplink and downlink multimedia service data. In a multimedia service scenario, the first measurement time period originally used for measurement is used to transmit scheduling information, which is beneficial to improving system capacity, thereby facilitating supporting more terminal devices to transmit multimedia service data in a multimedia service scenario. Exemplarily, the multimedia service data transmitted in a multimedia service scenario may include, but is not limited to, data such as video transmission, cloud gaming (CG) and extended reality (XR). These multimedia service data have the characteristic of a large amount of data. Due to limited transmission resources, the access network device can only schedule a small number of terminal devices to transmit multimedia service data. By transmitting scheduling information within the first measurement time period, it is beneficial to improve system capacity, thereby supporting more terminal devices to transmit multimedia service data. It should be noted that the embodiments of the present application can be applied not only in multimedia service scenarios, but also in other scenarios where the system capacity needs to be increased.

[0152] The CDRX cycle occurs periodically. In one implementation, taking the measurement skipping indicated by the first indication information as an example, the first CDRX cycle may include one or more CDRX cycles encountered after the terminal device receives the LPWUS, and the time when the terminal device receives the LPWUS is earlier than or equal to the start time of the first CDRX cycle. For example, the first CDRX cycle is the first CDRX cycle encountered after the terminal device receives the LPWUS. In this case, the first CDRX cycle includes one CDRX cycle. For another example, the first CDRX cycle may include multiple consecutive CDRX cycles encountered after the terminal device receives the LPWUS until the terminal device receives another LPWUS.

[0153] Optionally, for each CDRX cycle, the access network device can send an LPWUS to indicate the behavior of the terminal device within the measurement time period of the CDRX cycle. Specifically, the access network device sends multiple LPWUS, and the sending interval between two adjacent LPWUS in the multiple LPWUS is a first duration. Each LPWUS in the multiple LPWUS can indicate the behavior of the terminal device in the measurement time period of different CDRX cycles. The multiple LPWUS can be associated with multiple CDRX cycles, and one LPWUS in the multiple LPWUS can be associated with at least one CDRX cycle in the multiple CDRX cycles. For example, a schematic diagram of the access network device periodically sending LPWUS is shown in Figure 7. In Figure 7, multiple LPWUS include a first LPWUS and a second LPWUS as an example. The indication information a in the first LPWUS indicates the measurement skipping status for at least one measurement time period (including measurement time period a) in CDRX cycle 1; the indication information b in the second LPWUS indicates the measurement skipping status for at least one measurement time period (including measurement time period b) in CDRX cycle 2. In Figure 7, the first LPWUS is associated with CDRX cycle 1, and the second LPWUS is associated with CDRX cycle 2. In FIG7 , measurement period a is taken as part of the wake-up time of CDRX cycle 1, and measurement period b is taken as part of the wake-up time of CDRX cycle 2. In other possible implementations, measurement period a may be the entire wake-up time of CDRX cycle 1, and measurement period b may be the entire wake-up time of CDRX cycle 2. Optionally, the first duration may be the same as the duration of the CDRX cycle.

[0154] Optionally, if the access network device normally sends SSB in each measurement time period in the CDRX cycle, then the access network device may not send LPWUS associated with the CDRX cycle before the start time of the CDRX cycle. For the terminal device, before reaching the start time of the CDRX cycle, if the terminal device does not receive LPWUS associated with the CDRX cycle, then the terminal device can determine that the measurement skipping situation for each measurement time period in the CDRX cycle is to perform measurement, that is, the terminal device normally measures SSB in each measurement time period in the CDRX cycle.

[0155] In one implementation, the first indication information may be implemented as follows:

[0156] The first indication information is carried by the first bit, wherein, when the value of the first bit is a first value, the first indication information indicates that the measurement skipping situation of some or all measurement time periods in the Z measurement time periods is skip measurement, and the some measurement time periods include the first measurement time period; when the value of the first bit is a second value, the first indication information indicates that the measurement skipping situation for all measurement time periods in the Z measurement time periods is execution measurement. The first value and the second value are 1 and 0, respectively, or the first value and the second value are 0 and 1, respectively. The first bit may include at least one bit.

[0157] Taking the case where the first bit includes one bit and the first value is 1 as an example, in one implementation, when the value of the first bit is 1, the first indication information may indicate that the measurement skipping situation for all measurement time periods in the Z measurement time periods is skip measurement, and the terminal device does not measure SSB in each measurement time period in the Z measurement time periods. In another implementation, when the value of the first bit is 1, the first indication information may indicate that the measurement skipping situation for some measurement time periods in the Z measurement time periods is skip measurement, and the terminal device may monitor the scheduling information in each measurement time period of the Z measurement time periods. Optionally, the LPWUS also includes second indication information, and the second indication information may further indicate to the terminal device which measurement time period or time periods in the Z measurement time periods have the measurement skipping situation as skip measurement, and thus the terminal device does not measure SSB in these measurement time periods. For details about the content of the second indication information, please refer to the following text.

[0158] When the value of the first bit is 0, the first indication information may indicate that measurement is performed for all measurement time periods in the Z measurement time periods in the measurement skipping situation, and the terminal device may measure the SSB in each measurement time period in the Z measurement time periods.

[0159] The above describes that the first indication information can be used to indicate whether measurement needs to be skipped in the CDRX cycle. Next, it will be described how to use the second indication information to indicate which specific measurement time period or time periods in the CDRX cycle need to skip measurement when the first indication information indicates that measurement needs to be skipped in the CDRX cycle. Furthermore, the terminal device can skip measurement in these measurement time periods, which can save power consumption. For the access network device, SSB can be not sent in these measurement time periods, which can save power consumption. Optionally, these measurement time periods are used to transmit scheduling information. The terminal device can listen to the scheduling information in these measurement time periods. When the scheduling information is listened to and received, the uplink and downlink channels or uplink and downlink signals are transmitted based on the scheduling information. This is conducive to improving the system capacity, thereby supporting more terminal devices to transmit multimedia service data (such as XR service data) in multimedia service scenarios.

[0160] In one implementation, the LPWUS further includes second indication information, which may indicate a measurement skipping condition for each measurement time period in the Z measurement time periods. That is, the second indication information may indicate which measurement time period or time periods in the Z measurement time periods are skipped as measurement skipping conditions, so that the terminal device does not measure the SSB in these measurement time periods, which is conducive to saving power consumption.

[0161] Optionally, when the first indication information indicates that the measurement skipping situation for some measurement time periods within the CDRX cycle is skip measurement, the terminal device can further obtain, based on the second indication information, which measurement time period or time periods within the specific CDRX cycle whose measurement skipping situation is skip measurement. It can be understood that if the second indication information indicates that the measurement skipping situation for the first measurement time period among the Z measurement time periods is skip measurement (that is, the first measurement time period is the first measurement time period), then the terminal device may not measure the SSB within the first measurement time period. For other measurement time periods among the Z measurement time periods except the first measurement time period, the terminal device may measure the SSB within these measurement time periods.

[0162] Optionally, when the first indication information indicates that the measurement skipping situation for all measurement time periods within the CDRX cycle is skip measurement, the terminal device may not read the second indication information.

[0163] In one implementation, the second indication information may be implemented as follows:

[0164] Mode 1: The second indication information can be carried by at least one second bit, wherein the value of one second bit in the at least one second bit is used to indicate that the measurement skipping condition of one measurement time period in the Z measurement time periods is skip measurement. The number of second bits can be Z, and the Z second bits correspond one-to-one to the Z measurement time periods. The value of the second bit can be a first value or a second value. Taking Z=2 as an example, the Z measurement time periods include a first measurement time period and a second measurement time period. The second indication information is carried by the second bit a and the second bit b, wherein the first measurement time period corresponds to the second bit a, and the second measurement time period corresponds to the second bit b. If the value of the second bit corresponding to the first measurement time period (i.e., the second bit a) among the Z second bits is the first value, then it can be indicated that the measurement skipping condition for the first measurement time period is skip measurement. Furthermore, the terminal device may not measure the SSB in the first measurement time period. If the value of the second bit corresponding to the second measurement time period (i.e., the second bit b) in the Z second bits is the second value, then it can be indicated that the measurement skipping situation for the second measurement time period is to perform measurement. Further, the terminal device can measure SSB in the second measurement time period. In this way, both measurement can be skipped and measurement can be performed in the CDRX cycle, which is beneficial to saving power consumption while ensuring the communication quality of the terminal device. The first value and the second value are 1 and 0 respectively, or the first value and the second value are 0 and 1 respectively. Mode 1 can be understood as the second indication information indicating the measurement skipping situation of each measurement time period in the Z measurement time periods in the form of a bitmap, and the bitmap includes Z second bits.

[0165] Mode 2: The second indication information includes an index of a first measurement pattern in at least one measurement pattern (hereinafter referred to as a first measurement pattern set, the first measurement pattern set including at least one measurement pattern). Each measurement pattern in the first measurement pattern set can be used to indicate a measurement skipping status for each measurement time period in the Z measurement time periods. That is, the second indication information specifically indicates the measurement skipping status of each measurement time period in the Z measurement time periods through the first measurement pattern.

[0166] Table 1

[0167] For example, taking Z=3, the Z measurement time periods are measurement time period a, measurement time period b, and measurement time period c, the first measurement pattern set includes 8 measurement patterns, and the indexes of the 8 measurement patterns are 0-7, the content indicated by each measurement pattern in the first measurement pattern set can be seen in Table 1. In Table 1, √ can indicate that the measurement skipping condition of the corresponding measurement time period is skip measurement, and × can indicate that the measurement skipping condition of the corresponding measurement time period is perform measurement.

[0168] Exemplarily, if the index of the first measurement pattern included in the second indication information is 1, as shown in Table 1, the second indication information indicates that the measurement skipping condition for measurement time period a is skipping measurement, and the measurement skipping condition for measurement time periods b and c is performing measurement. Optionally, the second indication information may carry the index of the first measurement pattern via at least one bit. For example, for the eight measurement patterns shown in Table 1, the second indication information may carry the index of the first measurement pattern via three bits.

[0169] Optionally, the access network device may send configuration information, which may be used to configure the first measurement pattern set. Accordingly, the terminal device may receive the configuration information and, in combination with the first measurement pattern set configured in the configuration information and the index of the first measurement pattern in the second indication information, determine which measurement time periods in the Z measurement time periods the first measurement pattern specifically indicates are skipped measurements.

[0170] Optionally, the configuration information may be carried in Radio Resource Control (RRC).

[0171] It should be noted that, when a CDRX cycle includes only one measurement time period (the measurement time period being the first measurement time period), the first indication information may indicate the measurement skipping status for the first measurement time period, or the first indication information and the second indication information may jointly indicate the measurement skipping status for the first measurement time period. When a CDRX cycle includes at least two measurement time periods (one of which is the first measurement time period), the first indication information and the second indication information need to jointly indicate the measurement skipping status for each measurement time period in the CDRX cycle.

[0172] Regardless of whether the access network device indicates that the measurement skipping situation for the first measurement time period is skip measurement through the first indication information, or indicates that the measurement skipping situation for the first measurement time period is skip measurement through the first indication information and the second indication information. The measurement skipping situation for the first measurement time period is skip measurement, which can mean that the measurement skipping situation for some time units or all time units in the first measurement time period is skip measurement. Furthermore, the access network device can also indicate which specific time unit or time units in the first measurement time period are skip measurement through the third indication information. Furthermore, the terminal device can skip measurement in these time units, which can save power consumption. For the access network device, SSB can be not sent in these time units, which can save power consumption. Optionally, these time units are used to transmit scheduling information. The terminal device can listen to the scheduling information in these time units. When listening to and receiving the scheduling information, the terminal device transmits uplink and downlink channels or uplink and downlink signals based on the scheduling information. This is conducive to improving system capacity, thereby facilitating supporting more terminal devices to transmit multimedia service data (such as XR service data) in multimedia service scenarios.

[0173] In one implementation, the LPWUS may further include third indication information, where the third indication information indicates a measurement skipping condition for a first time within a first measurement time period, where a unit of the first time includes one or more of milliseconds, time slots, or symbols.

[0174] Among them, the unit of the first time includes milliseconds, which can be understood as: according to milliseconds (ms) or half a millisecond (0.5ms) as the indication granularity, the third indication information indicates which milliseconds (or half a millisecond) in the first measurement time period are skipped as skipped measurements (or, indicates which milliseconds (or half a millisecond) in the first measurement time period have scheduling information transmitted). The embodiment of the present application takes the example of indicating which milliseconds in the first measurement time period to skip measurements by the terminal device through the third indication information. These milliseconds can be called the first millisecond.

[0175] The first time unit includes time slots, which can be understood as: according to the time slot as the indication granularity, the third indication information can indicate which time slots in the first measurement time period have their measurement skipped as skipped measurement (or, indicate which time slots in the first measurement time period have scheduling information transmitted), and these time slots are called first time slots.

[0176] The unit of the first time includes symbols, which can be understood as: according to the symbol as the indication granularity, the third indication information can indicate which symbol or symbols in the first measurement time period are skipped for measurement (or, indicate which symbols in the first measurement time period are used to transmit scheduling information), and these symbols are called first symbols.

[0177] It can be understood that the first time may include one or more of the following: at least half a first millisecond, at least one first time slot, and at least one first symbol.

[0178] Optionally, the third indication information indicates that the measurement skipping condition for the first millisecond is skip measurement, and may further indicate that the measurement skipping condition for the first time slot within the first millisecond is skip measurement. This approach can be understood as the third indication information being notified in two levels, with the first level notifying the first millisecond and the second level notifying the first time slot. One millisecond may include at least one time slot. For example, taking a subcarrier spacing of 30 kHz as an example, the time slot length is 0.5 ms. In this case, 1 ms may include 2 time slots.

[0179] Optionally, the third indication information, in addition to indicating that the measurement skipping condition for the first time slot is skip measurement, may further indicate that the measurement skipping condition for the first symbol in the first time slot is skip measurement. This approach can be understood as the third indication information being notified in two levels, with the first level notifying the first time slot and the second level notifying the first symbol.

[0180] Optionally, the third indication information indicates that the measurement skipping condition of the first time slot within the first millisecond is skip measurement, and can further indicate that the measurement skipping condition of the first symbol within the first time slot is skip measurement. This method can be understood as the third indication information being divided into three levels of notification, the first level notifying the first millisecond, the second level notifying the first time slot, and the third level notifying the first symbol.

[0181] Based on the third indication information, the terminal device may not measure SSB (or listen to scheduling information) within the first millisecond, the first time slot and / or the first symbol, where the number of first milliseconds is at least one, the number of first time slots is at least one, and the number of first symbols is at least one.

[0182] The first measurement period may include multiple milliseconds, and the first millisecond may include all or part of the milliseconds in the first measurement period. The first measurement period may include multiple time slots, and the first time slot may include all or part of the time slots in the first measurement period. The first millisecond may include multiple time slots, and the first time slot may include all or part of the time slots in the first millisecond. The first time slot may include multiple symbols, and the first symbol may include all or part of the symbols in the first time slot. In the embodiments of the present application, the symbol may refer to an OFDM symbol.

[0183] The first measurement time period may include multiple milliseconds. For milliseconds other than the first millisecond in the first measurement time period (e.g., referred to as second milliseconds), the terminal device may perform measurements within the second milliseconds. The number of second milliseconds may be at least one. The first measurement time period may include multiple time slots. For time slots other than the first time slot in the first measurement time period (e.g., referred to as second time slots), the terminal device may perform measurements within the second time slots. The number of second time slots may be at least one. The first millisecond may include multiple time slots. For time slots other than the first time slot in the first millisecond (e.g., referred to as third time slots), the terminal device may perform measurements within the third time slots. The number of third time slots may be at least one. The first time slot may include multiple symbols. For symbols other than the first symbol in the first time slot (e.g., referred to as second symbols), the terminal device may perform measurements within the second symbol.

[0184] In one implementation, the third indication information may be implemented as follows:

[0185] Mode 3: The third indication information is carried by one or more of the following: at least one third bit, at least one fourth bit, and at least one fifth bit. The value of one third bit in the at least one third bit is used to indicate a half-millisecond or one-millisecond measurement skipping condition within the first measurement time period. The value of one fourth bit in the at least one fourth bit is used to indicate a measurement skipping condition for a timeslot within the first measurement time period. The value of one fifth bit in the at least one fifth bit is used to indicate a measurement skipping condition for a symbol within the first measurement time period. The values ​​of the third bit, the fourth bit, and the fifth bit can all be 1 or 0.

[0186] Taking the example of the first measurement time period including A milliseconds (A is an integer greater than or equal to 2) with milliseconds as the indication granularity, the value of one third bit in the at least one third bit is used to indicate: the measurement skipping of one millisecond in A milliseconds. The number of third bits can be A, and A third bits correspond one-to-one to A milliseconds. The value of the third bit can be 0 or 1. Taking the example of the first measurement time period including an SMTC window with a duration of 5 milliseconds (ms), the number of third bits can be 5, wherein the 1st bit, 2nd bit, 3rd bit, 4th bit, and 5th bit of the 5 third bits correspond to the 1st millisecond, 2nd millisecond, 3rd millisecond, 4th millisecond, and 5th millisecond in 5 milliseconds, respectively. Assuming that the value of the third bit is 1, it indicates that the measurement skipping condition of the millisecond corresponding to the third bit is skip measurement. When the values ​​of the five third bits are 11110, the third indication information indicates that the measurement skipping condition for the 1st to 4th milliseconds in the SMTC window is skip measurement, that is, the first millisecond includes the first 4 milliseconds in the SMTC window. Optionally, the terminal device can monitor the scheduling information within the 1st to 4th milliseconds in the SMTC window. Optionally, the third indication information can also indicate that the measurement skipping condition for the 5th millisecond in the SMTC window is execution measurement.

[0187] For another example, if the first measurement time period includes a measurement GAP, and the duration of the measurement GAP is 6 milliseconds (ms), the number of third bits can be 6, wherein the 1st bit, 2nd bit, 3rd bit, 4th bit, 5th bit, and 6th bit of the 6 third bits correspond to the 1st millisecond, 2nd millisecond, 3rd millisecond, 4th millisecond, 5th millisecond, and 6th millisecond in the 6 milliseconds, respectively. Assuming that the value of the third bit is 1, it indicates that the measurement skipping condition of the millisecond corresponding to the third bit is skip measurement. When the values ​​of the 6 third bits are 111110, the third indication information indicates that the measurement skipping condition for the 1st to 5th milliseconds in the SMTC window is skip measurement, that is, the first millisecond includes the first 5 milliseconds in the SMTC window.

[0188] Taking the example of a first measurement time period including B time slots (B is an integer greater than or equal to 2), the value of one of the at least one fourth bit is used to indicate whether measurement of one of the B time slots is skipped. The number of fourth bits can be B, with the B fourth bits corresponding one-to-one to the B time slots. The value of the fourth bit can be 0 or 1. Taking the first measurement time period including an SMTC window, SCS = 30 kHz, the duration of the SMTC window is 5 ms, and the SMTC window includes 10 time slots as an example, the number of fourth bits can be 10, where the 10 time slots are time slots 0 to time slot 9, and the 1st bit, 2nd bit, 3rd bit, 4th bit, 5th bit, 6th bit, 7th bit, 8th bit, 9th bit, and 10th bit of the 10 fourth bits correspond to time slot 0, time slot 1, time slot 2, time slot 3, time slot 4, time slot 5, time slot 6, time slot 7, time slot 8, and time slot 9, respectively. Assuming that the value of the fourth bit is 1, it indicates that the measurement skipping condition of the time slot corresponding to the fourth bit is skip measurement. When the value of the 10 fourth bits is 1111000000, the first time slot indicated by the third indication information may include the four time slots of time slot 0 to time slot 3. That is, the third indication information indicates that the measurement skipping condition for time slot 0 to time slot 3 in the SMTC window is skip measurement, that is, the first time slot includes time slot 0 to time slot 3. Optionally, the terminal device can monitor the scheduling information in time slot 0 to time slot 3. Optionally, the third indication information can also indicate that the measurement skipping condition for time slot 4 to time slot 9 in the SMTC window is execution measurement, that is, the terminal device can measure SSB in time slot 4 to time slot 9.

[0189] Taking the example of a first time slot including C symbols (C is an integer greater than or equal to 2), the value of one of the at least one fifth bit is used to indicate whether measurement of one of the C symbols is skipped. The number of fifth bits may be C, and the C fifth bits correspond one-to-one to the C time slots. The value of the fifth bit may be 0 or 1. The first time slot includes 14 symbols, and the number of fifth bits is 14, where the 14 symbols are symbol 0 to symbol 13, and the 1st bit, 2nd bit, 3rd bit, 4th bit, 5th bit, 6th bit, 7th bit, 8th bit, 9th bit, 10th bit, 11th bit, 12th bit, 13th bit, and 14th bit of the 14 fifth bits correspond to symbol 0, symbol 1, symbol 2, symbol 3, symbol 4, symbol 5, symbol 6, symbol 7, symbol 8, symbol 9, symbol 10, symbol 11, symbol 12, and symbol 13, respectively. Assuming that the value of the fifth bit is 1, it indicates that the measurement skipping condition of the symbol corresponding to the fifth bit is skip measurement. When the values ​​of the 14 fifth bits are 00111100111100, the fourth indication information indicates that the measurement skipping condition for symbols 2 to 5 and 8 to 11 in the SMTC window is skip measurement, that is, the first symbol includes 8 symbols of symbols 2 to 5 and 8 to 11. Optionally, the terminal device may not measure SSB in symbols 2 to 5 and 8 to 11, but monitor scheduling information. Optionally, the third indication information may also indicate that the measurement skipping condition for symbols 0 to 1, 6 to 7, and 12 to 13 in the SMTC window is execution measurement, that is, the terminal device may measure SSB in symbols 0 to 1, 6 to 7, and 12 to 13.

[0190] Mode 4: The third indication information includes one or more of the following: an index of the second measurement pattern, an index of the third measurement pattern, and an index of the fourth measurement pattern. The second measurement pattern is a measurement pattern in the second measurement pattern set, the third measurement pattern is a measurement pattern in the third measurement pattern set, and the fourth measurement pattern is a measurement pattern in the fourth measurement pattern set. Each measurement pattern in the second measurement pattern set is used to indicate the skipping of measurements for each half millisecond or each millisecond in the first measurement time period. That is, the third indication information may indicate the skipping of measurements for each half millisecond or each millisecond in the first measurement time period through the third measurement pattern. Each measurement pattern in the third measurement pattern set may be used to indicate the skipping of measurements for each time slot in the first measurement time period. That is, the third indication information may indicate the skipping of measurements for each time slot in the first measurement time period through the third measurement pattern. The measurement skipping condition of the first time slot in the first measurement time period is skipped measurement. Each measurement pattern in the fourth measurement pattern set can be used to indicate the measurement skipping condition for each symbol in the first time slot. That is, the third indication information can indicate the measurement skipping condition for each symbol in the first time slot through the fourth measurement pattern. In summary, the third indication information can indicate the measurement skipping condition for the first time through one or more of the second measurement pattern, the third measurement pattern, and the fourth measurement pattern.

[0191] For example, taking the example where the first measurement time period includes an SMTC window with a duration of 5 ms, the second measurement pattern set includes 8 measurement patterns, and each measurement pattern in the second measurement pattern set can be used to indicate a measurement skipping condition for each millisecond in the SMTC window, and the indexes of the 8 measurement patterns are 0-7, the content indicated by each measurement pattern in the second measurement pattern set can be seen in Table 2. In Table 2, √ may indicate that the measurement skipping condition for the corresponding millisecond is skip measurement, and × may indicate that the measurement skipping condition for the corresponding millisecond is execution measurement.

[0192] Table 2

[0193] Exemplarily, if the index of the second measurement pattern included in the third indication information is 6, as shown in Table 2, the third indication information can indicate that the measurement skipping condition for the 1st to 2nd milliseconds (i.e., the first 2 milliseconds) within the SMTC window is skip measurement, and can also indicate that the measurement skipping condition for the last 3 milliseconds within the SMTC window is execution measurement. Optionally, the third indication information can carry the index of the second measurement pattern via at least one bit. For example, for the 8 measurement patterns shown in Table 2, the third indication information can carry the index of the second measurement pattern via 3 bits.

[0194] For another example, taking the case where the first measurement time period includes one SMTC window, SCS=30 kHz, the duration of the SMTC window is 5 ms, the SMTC window includes 10 time slots, and the third measurement pattern set includes 16 measurement patterns, the 10 time slots are time slot 0 to time slot 9, and the indexes of the 16 measurement patterns are 0 to 15, the contents indicated by each measurement pattern in the third measurement pattern set can be seen in Table 3. In Table 3, √ may indicate that the measurement skipping condition of the corresponding time slot is skip measurement, and × may indicate that the measurement skipping condition of the corresponding time slot is perform measurement.

[0195] Table 3

[0196] Exemplarily, if the index of the third measurement pattern included in the third indication information is 15, as shown in Table 3, the third indication information may indicate that the measurement skipping condition for timeslots 0 to 3 is skip measurement, and may also indicate that the measurement skipping condition for timeslots 4 to 9 is perform measurement. Optionally, the third indication information may carry the index of the third measurement pattern via at least one bit. For example, for the 16 measurement patterns shown in Table 3, the third indication information may carry the index of the third measurement pattern via 4 bits.

[0197] For another example, taking the case where the first time slot includes time slot 0, time slot 0 includes 14 symbols, the fourth measurement pattern set includes 4 measurement patterns, the 14 symbols are symbol 0 to symbol 13, and the indexes of the 4 measurement patterns are 0 to 3, the contents indicated by each measurement pattern in the fourth measurement pattern set can be seen in Table 4. In Table 4, √ may indicate that the measurement skipping condition of the corresponding symbol is skip measurement, and × may indicate that the measurement skipping condition of the corresponding symbol is perform measurement.

[0198] Table 4

[0199] For example, if the index of the fourth measurement pattern included in the third indication information is 3, as shown in Table 4, the third indication information may indicate that the measurement skipping condition for symbols 2 to 5 and symbols 8 to 11 is skip measurement, and may also indicate that the measurement skipping condition for symbols 0 to 1, symbols 6 to 7, and symbols 12 to 13 is execution measurement. Optionally, the third indication information may carry the index of the fourth measurement pattern via at least one bit. For example, for the four measurement patterns shown in Table 4, the third indication information may carry the index of the fourth measurement pattern via two bits.

[0200] Optionally, in addition to being used to configure the first measurement pattern set, the aforementioned configuration information may also be used to configure one or more of the second measurement pattern set, the third measurement pattern set, and the fourth measurement pattern set. Accordingly, the terminal device, in combination with the measurement pattern set configured by the configuration information (including one or more of the first measurement pattern set, the second measurement pattern set, the third measurement pattern set, and the fourth measurement pattern set), the index of the first measurement pattern, the index of the second measurement pattern, the index of the third measurement pattern, and the index of the fourth measurement pattern, may determine which measurement time period or time periods in the CDRX cycle to skip measurement, which milliseconds (or half milliseconds) within the measurement time period to skip measurement, which time slots within the measurement time period to skip measurement, and which symbols within the time slot to skip measurement. In this way, a more detailed indication may be provided.

[0201] Each measurement time period in the CDRX cycle (including the first measurement time period) may include a time unit corresponding to at least one SSB (hereinafter referred to as M SSBs, where M is a positive integer), and the M SSBs may include all SSBs in an SS burst set. Taking the case where the frequency point of the cell sending the SSB belongs to the Sub3G~Sub6G frequency band, the cell can send up to 8 SSBs in the SMTC window. Taking the first measurement time period as the first SMTC window shown in Figure 2 as an example, the SMTC window includes time units corresponding to 2 SSBs. When the time unit is a time slot, the time unit corresponding to the first SSB in Figure 2 and the time unit corresponding to the second SSB are both time slot 0. When the time unit is a symbol, the time unit corresponding to the first SSB in Figure 2 may include symbols 2 to 5, and the time unit corresponding to the second SSB in Figure 2 may include symbols 8 to 11.

[0202] Next, it is introduced how to indicate through the fourth indication information which SSB or SSBs in the first measurement time period to skip measurement when the first indication information indicates that measurement needs to be skipped in the first measurement time period. Furthermore, the terminal device can skip measurement in the time units corresponding to these SSBs, which can save power consumption. For the access network device, SSBs may not be sent in the time units corresponding to these SSBs, which can save power consumption. Optionally, the time units corresponding to these SSBs are used to transmit scheduling information. The terminal device can listen to the scheduling information in the time units corresponding to these SSBs. When the scheduling information is listened to and received, the uplink and downlink channels or uplink and downlink signals are transmitted based on the scheduling information. This is conducive to improving the system capacity, thereby supporting more terminal devices to transmit multimedia service data (such as XR service data) in multimedia service scenarios.

[0203] In one implementation, the first measurement time period includes time units corresponding to M SSBs, and the LPWUS may further include fourth indication information. The fourth indication information may indicate a measurement skipping condition for the time units corresponding to the M SSBs, where the M SSBs include at least the first SSB, and the measurement skipping condition for the time unit corresponding to the first SSB includes: skipping the measurement of the first SSB in the time unit corresponding to the first SSB. It should be noted that the access network device no longer sends the SSB in the time unit corresponding to the first SSB. Accordingly, the terminal device does not measure the SSB in the time unit corresponding to the first SSB. The number of the first SSB may be one or more.

[0204] Optionally, the terminal device may monitor the scheduling information within the time unit corresponding to the first SSB, and upon monitoring and receiving the scheduling information, transmit the uplink and downlink channels or uplink and downlink signals based on the scheduling information. It should be noted that the access network device transmits the scheduling information within the time unit corresponding to the first SSB, and the access network device no longer sends the SSB within the time unit corresponding to the first SSB. Accordingly, the terminal device does not measure the SSB within the time unit corresponding to the first SSB, but monitors and receives the scheduling information.

[0205] Optionally, the access network device transmits a second SSB within the time unit corresponding to other SSBs (such as the second SSB) among the M SSBs except the first SSB. Accordingly, the terminal device can measure the second SSB within the time unit corresponding to the second SSB.

[0206] In one implementation, the fourth indication information may include an index of the first SSB. The terminal device may determine the index of the first symbol of the first SSB based on the index of the first SSB and the aforementioned Case A to Case F. One SSB occupies four symbols. Therefore, the terminal device may determine the positions of the four symbols of the first SSB based on the index of the first symbol of the first SSB, and then skip measurement on these four symbols. Optionally, the terminal device may also monitor scheduling information on these four symbols.

[0207] In another implementation, the fourth indication information may include a beam index, and the terminal device may determine the first SSB based on the beam index and the correspondence between the beam index and the SSB index, where the beam index in the fourth indication information corresponds to the index of the first SSB. One beam index corresponds to one SSB index.

[0208] In one implementation, the fourth indication information may be implemented as follows:

[0209] Mode 5: The fourth indication information is carried by at least one sixth bit, wherein the value of one sixth bit in the at least one sixth bit is used to indicate that the measurement skipping condition of the time unit corresponding to one SSB in the M SSBs is skip measurement. The number of sixth bits may be M, and the M sixth bits correspond one-to-one to the M SSBs. The value of the sixth bit may be 0 or 1. Taking M=2 as an example, the M SSBs include SSB-0 and SSB-1, wherein the index of SSB-0 is 0, and the index of SSB-1 is 1. The fourth indication information is carried by the sixth bit a and the sixth bit b, wherein SSB-0 corresponds to the sixth bit a, and SSB-1 corresponds to the sixth bit b. If among the M sixth bits, the value of the sixth bit a corresponding to SSB-0 is 1, and the value of the sixth bit b corresponding to SSB-1 is 0, then it can be indicated that the measurement skipping situation for the time unit corresponding to SSB-0 is skip measurement, and the measurement skipping situation for the time unit corresponding to SSB-1 is execution measurement. Furthermore, the terminal device may not measure SSB in the time unit corresponding to SSB-0, and measure SSB in the time unit corresponding to SSB-1.

[0210] Method 6: The fourth indication information may include an index of a fifth measurement pattern in at least one measurement pattern (hereinafter referred to as the fifth measurement pattern set, the fifth measurement pattern set including at least one measurement pattern), and each measurement pattern in the fifth measurement pattern set can be used to indicate the measurement skipping status of the time unit corresponding to each SSB in the M SSBs. That is, the fourth indication information specifically indicates the measurement skipping status of the time unit corresponding to each SSB in the M SSBs through the fifth measurement pattern.

[0211] For example, taking the case where the first measurement time period includes 8 time units corresponding to SSBs, and the fifth measurement pattern set includes 16 measurement patterns, the 8 SSBs are SSB-0, SSB-1, SSB-2, SSB-3, SSB-4, SSB-5, SSB-6, and SSB-7, where i in SSB-i represents the index of the SSB. Taking the case where the indexes of the 16 measurement patterns are 0-15, the contents indicated by each measurement pattern in the fifth measurement pattern set can be seen in Table 5. In Table 5, √ can indicate that the measurement skipping condition for the time unit corresponding to the SSB is skip measurement, and × can indicate that the measurement skipping condition for the time unit corresponding to the SSB is perform measurement.

[0212] Table 5

[0213] For example, if the index of the fifth measurement pattern included in the fourth indication information is 15, as shown in Table 5, the fourth indication information may indicate that the measurement skipping conditions for the time units corresponding to SSB-0, SSB-1, SSB-2, SSB-3, SSB-4, SSB-5, SSB-6, and SSB-7 are all skip measurements.
