Communication method and apparatus
[0001] The present application claims priority from the Chinese patent application No. 202410868407.X filed on June 28, 2024, and entitled "Communication method and apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD
[0002] The present application relates to the field of communication, in particular to a communication method and apparatus. BACKGROUND
[0003] At present, many energy saving features of terminal devices are standardized in the fifth generation (5th generation, 5G) communication network, but the energy saving features belong to optimization features. Due to various reasons, such as, operator cost increase, network key performance indication (key performance indication, KPI) will decrease, market prospect is unclear, etc., most of the energy saving features are not opened for commercial use. At the same time, there are many measurement features defined in the 5G communication network, which may cause different measurement resources or different reporting resources to be distributed on different resources, so that the terminal device is always woken up for measurement and / or reporting, and cannot enter sleep or hibernate state, thereby causing high power consumption of the terminal device.
[0004] Therefore, how to reduce the power consumption of the terminal device is a problem to be solved. SUMMARY
[0005] Embodiments of the present application provide a communication method and apparatus to reduce the power consumption of the terminal device.
[0006] To achieve the above-mentioned purpose, the embodiments of the present application adopt the following technical solutions:

The first device can be a terminal device, a module (such as a processor, a chip, or a chip system, etc.) applied to the terminal device, or a logic node, a logic module, or software capable of realizing all or part of the functions of the terminal device. The method comprises: obtaining a measurement area and performing measurement in the measurement area. The measurement area is used for the first device to measure at least one reference signal and / or at least one measurement function only in the measurement area. Any one of the at least one reference signal is used for measurement of one or more measurement functions.
[0008] Based on the method in the first aspect, the first device can measure the at least one reference signal and / or the at least one measurement function only in the measurement area, and not measure the at least one reference signal and / or the at least one measurement function outside the measurement area. In this way, the measurement of the at least one reference signal or the at least one measurement function can be concentrated or aggregated in the measurement area, so as to avoid the problem that the at least one reference signal or the at least one measurement function needs to be measured on different resources, and the first device is always woken up for measurement, thereby reducing the power consumption of the first device (which can be a terminal device).
[0009] In a possible design, the measurement in the measurement area includes: receiving the first reference signal in the measurement area, and / or sending a measurement result corresponding to the first reference signal in the measurement area. The at least one reference signal includes the first reference signal. That is, the measurement of the first device in the measurement area includes: in the measurement area, the first device receives the first reference signal, measures the first reference signal, and reports a measurement result corresponding to the first reference signal, so that subsequent operations of other devices (such as the second device) can be performed according to the measurement result, without limitation.
[0010] In a possible design, the method in the first aspect further includes: performing communication in the measurement area. That is, the first device can perform measurement in the measurement area, and also perform communication.

[0108] For example, radio resource management (RRM), radio link monitoring (RLM), or beam failure recovery (BFR) measurements can be measured by SSB or CSI-RS; time domain synchronization or time-frequency offset estimation measurements can be measured by SSB or TRS; beam measurements can be measured by SSB or CSI-RS; initial access measurements can be measured by SSB; phase tracking measurements can be measured by PTRS; and the like, without limitation.
[0109] 2. Resource
[0110] In a communication protocol, a reference signal is usually configured in the form of a resource, and the reference signal can occupy the resource, which can be referred to as a reference signal resource. The network device configures each reference signal in the form of a resource to the terminal device, and one resource is one configuration information unit, which usually includes a parameter related to the reference signal, such as a time-frequency resource position of the reference signal, a port number, a time domain type (periodic / semi-static / non-periodic), and the like. The resource can be an uplink signal resource or a downlink signal resource.
[0111] The resource can be configured by a radio resource control (RRC) message. In terms of configuration structure, one resource is a data structure including parameters related to the corresponding uplink / downlink signal. For example, the type of the uplink / downlink signal, the resource granularity carrying the uplink / downlink signal, the transmission time and period of the uplink / downlink signal, the number of ports used for transmitting the uplink / downlink signal, and the like. Each uplink / downlink signal resource has a unique identifier to identify the uplink / downlink signal resource. It can be understood that the identifier of the resource can also be referred to as the identifier of the signal, and the embodiments of the present application do not make any limitation in this regard.
[0112] 3. Semi-persistent scheduling (SPS) scheduling
[0113] The SPS scheduling can also be referred to as semi-persistent transmission, which can refer to that the network device uses a scrambled physical downlink control channel (PDCCH) to specify the wireless resource (hereinafter referred to as SPS resource) used by the terminal device in a certain transmission time interval (TTI), and the terminal device can use the SPS resource to receive or transmit data every period. The network device does not need to issue a PDCCH to specify the allocated resource in each scheduling time slot. Compared with dynamic scheduling, the scheduling parameters are relatively fixed, and are not dynamically adjusted, which reduces the number of blind detections of downlink control information (DCI), and can reduce the latency and power consumption of the terminal device.
[0114] The SPS scheduling can include downlink semi-persistent scheduling (DL SPS), uplink configured grant type 1 (type 1), and uplink configured grant type 2 (type 2).
[0115] Among them, (1) DL SPS: the network device configures periodic downlink resources for the terminal device; activated (the resource becomes a valid resource) / deactivated (the resource becomes an invalid resource) by a DCI; the terminal device can only perform downlink transmission when the resource is valid. (2) Uplink configured grant type 1: the network device configures uplink periodic resources for the terminal device; once configured, the resource is valid, and the validity and invalidity of the resource do not need to be activated / deactivated by DCI, and can only be changed by RRC reconfiguration, for example, by the method of RRC reconfiguration to release the resource. (3) Uplink configured grant type 2: the network device configures uplink periodic resources for the terminal device; activated / deactivated by a DCI; the terminal device can only perform uplink transmission when the resource is valid.
[0116] In the fifth generation (5th generation, 5G) communication network, the power consumption of the terminal device when the initial protocol version product is 3 times that of the terminal device in the fourth generation (4th generation, 4G) communication network, the heat dissipation problem is serious, and the user experience is very bad. With the evolution of the 3rd generation partnership project (3rd generation partnership project, 3GPP) release (release, R) 16-R19 protocol, many energy-saving features of the terminal device are standardized in each version, and in addition to product and network joint optimization, the power consumption of the current terminal device is controlled. However, this energy-saving feature belongs to an optimization feature, and due to various reasons, such as increased operator costs, decreased network key performance indicators (key performance indicators, KPIs), and unclear market prospects, most energy-saving features are not turned on for commercial use. Therefore, the 5G communication network has not well solved the power consumption problem.
[0117] At the same time, there are many measurement features (or measurement functions) defined in the 5G communication network, which can cause measurement resources or reporting resources to be distributed or diffused in different dimensions of resources (such as time domain, frequency domain, spatial domain, code domain, and power domain), and there are periodic measurements (measurements and / or reporting), aperiodic measurements, semi-persistent scheduling, and other ways, and the measurement resources and reporting resources depend on the configuration and indication of the network device. However, due to the flexibility of the network device, the configuration and indication of the network device can cause different measurement resources or different reporting resources to be distributed on different resources. In this case, the terminal device can always be woken up for measurement and / or reporting, and cannot enter a sleep or hibernate state, resulting in high energy consumption of the terminal device.
[0118] For example, taking the distribution of measurement resources or reporting resources in the time domain as an example, FIG. 1 is a distribution diagram of multiple measurement resources, as shown in FIG. 1, the horizontal axis is time (t); taking a reference signal as SSB, TRS, CRS-RS (resource period distribution), a transmission mode as downlink SPS transmission, and a reference signal resource as an example, the reference signal resource is periodically distributed in the time domain. Among them, the period of SSB resource is 20 milliseconds (ms), the period of TRS resource is 10 ms, the period of CRS-RS is 25 ms, and the period of downlink SPS is 30 ms, and the SSB resource, the TRS resource, the CRS-RS resource and the SPS resource are distributed at different times, so that the terminal device is always woken up and cannot enter a sleep or hibernate state, resulting in high power consumption of the terminal device.
[0119] In addition, in future communication networks, the scenarios and requirements are more complex than in 5G, and the demand indicators have higher requirements. In the face of more scenarios and greater demands in future communication networks, network devices or terminal devices will face challenges such as greater bandwidth, faster processing speed, more antennas, and the first big challenge is power consumption. For network devices, high power consumption will increase operating costs; for terminal devices, in the case of limited growth in size, area, battery capacity, etc., high power consumption and heat dissipation problems bring greater challenges. In view of the problems faced in 5G communication networks, and considering current and future energy shortages and environmental problems, sustainability can be one of the original requirements for future communication networks.
[0120] Therefore, how to reduce the power consumption of the terminal device is a problem to be solved.
[0121] In summary, in view of the above technical problems, the technical solutions of the embodiments of the present application are proposed to reduce the power consumption of the terminal device.

[0130] To facilitate understanding of the embodiments of the present application, first, a communication system shown in FIG. 2 is taken as an example to explain the communication system applicable to the embodiments of the present application in detail. For example, FIG. 2 is a schematic diagram of an architecture of a communication system applicable to a communication method provided by the embodiments of the present application.
[0131] As shown in FIG. 2, the communication system mainly includes a network device and a terminal device.
[0132] The network device can be multiple, such as a first network device, a second network device, a third network device, etc. The network device can be a device with wireless transceiving function, or can also be a chip or chip system arranged in the device, located in the access network (AN) of the communication system, and used to provide access services for terminals. For example, the network device can be referred to as a radio access network (RAN) device, which can be specifically an access network device in a future communication system, or in a future mobile communication system, the network device can also have other naming ways, which are all included in the protection scope of the embodiments of the present application, and the embodiments of the present application do not make any limitation on this. Or, the network device can also include 5G, such as gNB in a new radio (NR) system, or one or a group (including multiple antenna panels) of antenna panels of a base station in 5G, or it can also be a network node constituting a gNB, a transmission and reception point (TRP or transmission point, TP) or a transmission measurement function (TMF), such as a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), an RSU with base station function, or a wired access gateway, or a core network element of 5G, etc. Or, the network device can also include: an access point (AP) in a wireless fidelity (WiFi) system, a wireless relay node, a wireless backhaul node, various forms of macro base stations, micro base stations (also known as small stations), relay stations, access points, wearable devices, vehicle-mounted devices, etc.

In addition, the CU can be divided into a network device in an access network RAN, or the CU can be divided into a network device in a core network CN, which is not limited herein.
[0134] In different systems, the CU (or CU-CP and CU-UP), the DU, or the RU can also have different names, but those skilled in the art can understand their meanings. For example, in an ORAN system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. For the convenience of description, the CU, the CU-CP, the CU-UP, the DU, and the RU are taken as examples for description in this application. Any one of the CU (or the CU-CP, the CU-UP), the DU, and the 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.
[0135] In the embodiments of this application, the form of the network device is not limited, and the device for implementing the function of the network device can be the network device; or can be a device capable of supporting the network device to implement the function, such as a chip system. The device can be installed in the network device or used in matching with the network device.
[0136] The terminal device can be an apparatus or module with corresponding communication functions for accessing the above communication system. The terminal device can be one or more, such as a first terminal device, a second terminal device, a third terminal device, and the like. The terminal device can be a terminal device with transceiver functions, or can also be a chip or chip system provided in the terminal device. The terminal device can also be referred to as a user equipment (UE), an access terminal device, a subscriber unit, a user station, a mobile station (MS), a mobile station, a remote station, a remote terminal device, a mobile device, a user terminal device, a terminal device, a wireless communication device, a user agent, or a user apparatus.

The terminal device can also be other devices with terminal device functions, for example, the terminal device can also be a device with terminal device functions in D2D communication.
[0137] Embodiments of the present application do not limit the form of the terminal device, and the device for implementing the function of the terminal device can be the terminal device, or can be a device capable of supporting the terminal device to implement the function, such as a chip system. The device can be installed in the terminal device or used in combination with the terminal device. In embodiments of the present application, the chip system can be composed of a chip, or can include a chip and other discrete devices. The terminal device is usually provided with a communication module, circuit or chip for performing a corresponding communication function. The terminal device also has program instructions configured to perform a corresponding communication function.
[0138] It can be understood that in embodiments of the present application, the first device can be the network device or the terminal device as described above; the second device can be the network device or the terminal device, without limitation.
[0139] In the communication system, the first device can only measure the at least one reference signal and / or measure the at least one measurement function (measurement and / or reporting) in the measurement area, and does not measure the at least one reference signal and / or measure the at least one measurement function outside the measurement area. In this way, centralized measurement or aggregated measurement of the at least one reference signal or the at least one measurement function can be realized in the measurement area, so as to avoid the problem that the at least one reference signal or the at least one measurement function needs to be measured on different resources, and the first device is always woken up for measurement, thereby reducing the power consumption of the first device (which can be a terminal device).
[0140] The communication system shown in FIG. 2 can be used in the architecture of different communication systems, for example, it can be applicable to the open-radio access network (O-RAN) system shown in FIG. 3. As shown in FIG. 3, the network device described above can be a RAN (for example, it can be an eNB or a gNB or a future access network device). The RAN can communicate with the core network (CN) through a backhaul link, and communicate with the UE through an air interface.
[0141] Among them, the baseband unit (BBU) in the access network device communicates with the core network through the backhaul link, and the radio unit (RU) in the access network device communicates with at least one UE through the air interface. The BBU communicates with at least one RU through the front transmission link, and the BBU and the RU can be co-located or not. The BBU includes at least one CU and at least one DU, which can communicate through at least one midhaul.
[0142] Figure 4 is a schematic diagram of a network element function split and protocol layer structure of an O-RAN device, as shown in Figure 4, including an access network device and a management system. In some examples, the CU is a logical node that hosts the radio resource control (RRC) layer, the service data adaptation protocol (SDAP) layer, the packet data convergence protocol (PDCP) layer, and other control functions of the access network device. The CU is connected to network nodes such as a core network via some interfaces, which can be E2 interface or the like. Optionally, the CU can have part of the functions of the core network. The CU (e.g., the PDCP layer and higher layers) is connected to the DU (e.g., the RLC layer and lower layers) via some interfaces, which can be F1 interface or the like. In some examples, these interfaces (e.g., the F1 interface) can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). The F1AP is an application protocol of the F1 interface, which defines the signaling procedures of the F1 in some examples. The F1 interface supports a control plane F1-C and a user plane F1-U.
[0143] In some examples, the CU can be split into a CU-CP and a CU-UP, where the CU-CP is a logical node that hosts the RRC layer and the control plane part of PDCP (PDCP-C) layer, for implementing the control plane functions of the CU. The CU-CP can interact with a network element in the core network for implementing the control plane functions. The network element in the core network for implementing the control plane functions can be an access and mobility function network element, such as an access and mobility management function (AMF) in a 5G system. The AMF network element is responsible for mobility management in the mobile network, such as location updating of terminal devices, registration of terminal devices to the network, handover of terminal devices, etc. The CU-UP is a logical node that hosts the SDAP layer and the user plane part of PDCP (PDCP-U) layer, for implementing the user plane functions of the CU. The CU-UP can interact with a network element in the core network for implementing the user plane functions. The network element in the core network for implementing the user plane functions can be a user plane function (UPF) in a 5G system, which is responsible for forwarding and receiving data in terminal devices.
[0144] The above configuration of CU and DU is merely an example, and the CU and DU can be configured to have functions as needed. For example, the CU or the DU can be configured to have functions of more protocol layers, or the CU or the DU can be configured to have partial processing functions of the protocol layers. For example, partial functions of the RLC layer and functions of the protocol layers above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and functions of the protocol layers below the RLC layer are arranged in the DU. For another example, the functions of the CU or the DU can be divided according to a service type or other system requirements, for example, according to a delay requirement. For example, functions that require a processing time to meet a delay requirement are arranged in the DU, and functions that do not require the delay requirement are arranged in the CU.
[0145] In some examples, the DU is a logical node that carries a radio link control (RLC) layer, a medium access control (MAC) layer, a higher physical layer (Higher PHY), and other functions. In some examples, the DU can control at least one RU. The DU is connected to the RU through some interfaces, which can be a front-haul interface. In some examples, the Higher PHY includes part of the PHY processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, and other processing functions.
[0146] In some examples, the RU is a logical node that carries a lower physical layer (Lower PHY) and radio frequency (RF) processing. In some examples, the RU can be a 3rd generation partnership project (3GPP) TRP or a remote radio head (RRH) or other similar functional entity. In some examples, the Low-PHY includes part of the PHY processing, such as fast Fourier transform (FFT), inverse fast fourier transformation (IFFT), digital beamforming and filtering, and other processing functions. The RU communicates with one or more UEs through a wireless link.
[0147] The DU and the RU can or can not be co-located. The DU and the RU exchange control plane information and user plane information via a lower-layer split-control, user and synchronization (LLS-CUS) interface over a fronthaul link. The LLS-CUS can include a LLS-C interface and a LLS-U interface that provide a control plane (C-Plane) and a user plane (U-Plane), respectively. In some examples, the control plane (C-Plane) refers to real-time control between the DU and the RU. The DU and the RU exchange management information via a LLS-M interface of the fronthaul link, and the management plane (M-Plane) refers to non-real-time management operation between the DU and the RU.
[0148] The DU and the RU can cooperate to jointly implement the functions of the PHY layer. One DU can be connected to one or more RUs. The functions of the DU and the RU can be configured in multiple ways according to design. For example, the DU is configured to implement baseband functions, and the RU is configured to implement intermediate radio frequency functions. For another example, the DU is configured to implement high-layer functions in the PHY layer, and the RU is configured to implement low-layer functions in the PHY layer or to implement the low-layer functions and radio frequency functions. The high-layer functions in the PHY layer can include a portion of the functions of the PHY layer that are closer to the MAC layer, and the low-layer functions in the PHY layer can include another portion of the functions of the PHY layer that are closer to the intermediate radio frequency side.
[0149] For example, FIG. 5 is a schematic diagram of another architecture of a communication system to which the communication method provided in the embodiments of the present application is applied. As shown in FIG. 5, the communication between the network device and the terminal device in the communication system can also be represented in another form. The terminal device 10 includes a processor 101, a memory 102, and a transceiver 103, and the transceiver 103 includes a transmitter 1031, a receiver 1032, and a plurality of antennas 1033 (antenna panels). The network device 20 includes a processor 201, a memory 202, and a transceiver 203, and the transceiver 203 includes a transmitter 2031, a receiver 2032, and at least one antenna 2033 (antenna panel). The receiver 1032 can be configured to receive transmission control information through the antennas 1033, and the transmitter 1031 can be configured to send transmission feedback information to the network device 20 through the antennas 1033. The transmitter 2031 can be configured to send transmission control information to the terminal device 10 through the antennas 2033, and the receiver 2032 can be configured to receive transmission feedback information sent by the terminal device 10 through the antennas 2033.
[0150] It can be understood that FIG. 2 and FIG. 5 are only simplified schematic diagrams for the purpose of understanding, and other network devices and / or other terminal devices can also be included in the communication system, which are not shown in FIG. 2 and FIG. 5.
[0151] For the purpose of convenient understanding, the communication method provided by the embodiments of the present application will be described in detail below in combination with FIG. 6-FIG. 12.
[0152] For example, FIG. 6 is a flow diagram of the communication method provided by the embodiments of the present application. The communication method is applicable to the communication between the first device and the second device in the above-mentioned communication system.
[0153] Specifically, as shown in FIG. 6, the flow of the communication method is as follows:
[0154] S601, the first device acquires a measurement region.
[0155] S602, the second device acquires (or determines) the measurement region.
[0156] S603, the second device sends a first reference signal to the first device in the measurement region. Correspondingly, the first device receives the first reference signal from the second device in the measurement region.
[0157] S604, the first device performs measurement in the measurement region.
[0158] The related content in the above-mentioned steps S601-S604 will be described in detail below.
[0159] For the above-mentioned step S601:
[0160] The measurement region can be used for the first device to perform measurement on at least one reference signal and / or at least one measurement function only in the measurement region.
[0161] The reference signal can be a known signal, and the reference signal can include an uplink reference signal and a downlink reference signal. The uplink reference signal can be used for uplink channel estimation (such as coherent demodulation and detection for a network device or for calculating precoding), or uplink channel quality measurement, etc. The downlink reference signal can be used for downlink channel estimation (such as coherent detection and demodulation for a terminal device), downlink channel quality measurement, or cell search, etc. The at least one reference signal can include at least one of the following: a CSI-RS, an SSB, a PSS, an SSS, a TRS, a PTRS, a DMRS, a CRS, a PSS, an SRS, an on-off keying (OOK) signal, an orthogonal frequency division multiplexing (OFDM), an OFDM-derived channel, an orthogonal time frequency space (OTFS), a sensing signal, an artificial intelligence (AI) signal, a pseudo-random sequence, a Zadoff-Chu (ZC) sequence, an m-sequence, an M-sequence, a discrete cosine transform (DCT) sequence, a discrete Fourier transform (DFT) sequence, a Gold sequence, a wake-up signal, a low-power wake-up signal (such as a power less than a preset value), etc. That is, the existing reference signal can be multiplexed to reduce the implementation difficulty, or a new reference signal can be used to improve the implementation flexibility, without limitation.
[0162] Any one of the at least one reference signal can be used for measurement of one or more measurement functions, which can be used to characterize the purpose of measurement, and the multiple measurement functions can correspond to multiple different types of measurements or multiple different measurement characteristics. The at least one measurement function (at least one type of measurement or at least one measurement characteristic) can include at least one of the following: cell measurement, channel measurement, time-frequency measurement, phase measurement, beam measurement, (total) radiated power (TRP) measurement, sensing measurement, AI measurement, timing advance measurement, or can also be or any other possible measurement function, without limitation. In addition, the multiple measurement functions can also be different in terms of measurement parameters, such as periodic measurement, semi-persistent measurement, aperiodic measurement, etc., which can also be considered as multiple measurement functions, and the embodiments of the present application do not limit this.
[0163] For example, the at least one reference signal can be a synchronization signal block (SSB) which can be used for cell measurement, beam measurement, initial access measurement, etc. For example, the at least one reference signal can be a channel state information reference signal (CSI-RS) which can be used for channel measurement, beam measurement, etc. For example, the at least one reference signal can be a phase tracking reference signal (PTRS) which can be used for phase measurement, etc.
[0164] It can be understood that any of the at least one reference signal can be associated with any physical channel (i.e., a channel carrying the reference signal). For example, a physical uplink control channel (PUCCH), a physical downlink control channel (PDCCH), a physical uplink shared channel (PUSCH), a physical downlink shared channel (PDSCH), a physical random access channel (PRACH), etc. It can be understood that the first device can also directly measure the physical channel only in the measurement area, and not measure the physical channel outside the measurement area, etc., without limitation.
[0165] Based on the above description, the measurement area can be an area composed of wireless resources (i.e., a measurement resource unit), and can include one or more areas, without limitation. The measurement area can be an area composed of at least one resource in the time domain, the frequency domain, the spatial domain, the code domain, or the power domain. The first device only measures the at least one reference signal and / or concentrates or aggregates the at least one measurement function in the measurement area, and does not measure the at least one reference signal and / or the at least one measurement function outside the measurement area. The first device only measuring the at least one reference signal in the measurement area can include that the first device only measures the at least one reference signal and / or reports the measurement result corresponding to the at least one reference signal in the measurement area. The first device measuring the at least one measurement function can include that the first device measures and / or reports the at least one measurement function. That is, the above measurement area can also be understood as a reporting area, without limitation.
[0166] Exemplarily, taking that the first device only measures at least one reference signal in the measurement region as an example, the at least one reference signal can include SSB, TRS, and CSI-RS. As shown in FIG. 7, the first device can centrally measure SSB, TRS, and CSI-RS on resources in the measurement region (in the dashed box) and will not measure SSB, TRS, and CSI-RS on other resources outside the measurement region (outside the dashed box).
[0167] In a possible design, the configuration resource corresponding to the at least one reference signal is in the measurement region.
[0168] The configuration resource can include a measurement resource and / or a reporting resource. The measurement resource can be used for receiving and / or measuring the at least one reference signal, and the reporting resource can be used for reporting a measurement result of the at least one reference signal. It can be understood that the network side can preconfigure resources occupied by each of the at least one reference signal in the measurement resource unit corresponding to the measurement region, so as to ensure that the first device only measures the at least one reference signal in the measurement region and / or centrally measures at least one measurement function.
[0169] Exemplarily, taking FIG. 7 as an example, for SSB, TRS, and CSI-RS, the network side (the second device described below) can make the configuration resource corresponding to SSB, TRS, and CSI-RS be in the measurement region (in the dashed box) by adjusting a resource period of SSB, TRS, and CSI-RS, or predefining or preconfiguring the resource period of SSB, TRS, and CSI-RS, and the like, which is not limited in the embodiments of the present application.
[0170] It should be noted that if there are at least two reference signals in the measurement region, such as SSB and TRS occupying the same resource, the network side (the second device described below) can move the resource occupied by SSB or TRS by one resource unit (the moved resource still belongs to the measurement region) by sending indication information, such as indication information #a, to the first device, or preconfigure or predefine a rule that when there are at least two reference signals (such as SSB and TRS) occupying the same resource in the measurement region, the first device moves the resource occupied by SSB or TRS by one resource unit (the moved resource still belongs to the measurement region), and the like, so that the resources occupied by SSB and TRS in the measurement region do not coincide, thereby improving the measurement accuracy and precision of each reference signal.
[0171] In a possible design, the measurement region can include a first measurement region and a second measurement region.
[0172] The first measurement area can be used for regular measurement, and the second measurement area can be used for burst measurement. The first measurement area and the second measurement area are described below.
[0173] The first measurement area can be at least one of a periodic area, a semi-persistent area, an area with a bandwidth less than or equal to a first bandwidth, an area with a port number less than or equal to a first port number, an area with power consumption less than or equal to a first power consumption, or an area with a power less than or equal to a first power.
[0174] The periodic area can be an area composed of a time domain dimension, such as an area between a first time and a second time, and can be used for the first device to measure a periodic reference signal (resource). The semi-persistent area can be used for the first device to measure a semi-persistent reference signal (resource). The area with a bandwidth less than or equal to the first bandwidth can be used for the first device to measure a reference signal with a bandwidth less than or equal to the first bandwidth. The area with a port number less than or equal to the first port number can be used for the first device to measure a reference signal with a transmission antenna port number less than or equal to the first port number. The area with power consumption less than or equal to the first power consumption can be used for the first device to measure a reference signal with power consumption less than or equal to the first power consumption. The area with a power less than or equal to the first power can be used for the first device to measure a reference signal with a transmission power less than or equal to the first power. It can be understood that the first measurement area can also be used for other measurements, for example, the first device can measure a reference signal using a code number less than or equal to the first code number, and the like, without limitation.
[0175] The second measurement area can be at least one of a non-periodic area, an area with a bandwidth greater than or equal to a second bandwidth, an area with a port number greater than or equal to a second port number, an area with power consumption greater than or equal to a second power consumption, or an area with a power greater than or equal to a second power.
[0176] The non-periodic area can be used for the first device to measure a non-periodic reference signal (resource). The area with a bandwidth greater than or equal to the second bandwidth can be used for the first device to measure a reference signal with a bandwidth greater than or equal to the second bandwidth. The area with a port number greater than or equal to the second port number can be used for the first device to measure a reference signal with a transmission antenna port number greater than or equal to the second port number. The area with power consumption greater than or equal to the second power consumption can be used for the first device to measure a reference signal with power consumption greater than or equal to the second power consumption. The area with a power greater than or equal to the second power can be used for the first device to measure a reference signal with a transmission power greater than or equal to the second power. It can be understood that the second measurement area can also be used for other measurements, for example, the first device can measure a reference signal using a code number greater than the second code number, measure a high-speed moving object, and the like, without limitation.
[0177] The second bandwidth can be greater than the first bandwidth, the second port number can be greater than the first port number, the second power consumption can be greater than the first power consumption, the second power can be greater than the first power, and the second encoding number can be greater than the first encoding number. The embodiments of the present application do not limit the specific values of the first bandwidth, the second bandwidth, the first port number, the second port number, the first power consumption, the second power consumption, the first power, the second power, the first encoding number, and the second encoding number. It can be understood that the first measurement area and the second measurement area can also have a partially overlapping case, for example, the first bandwidth is greater than the second bandwidth, the first port number is greater than the second port number, the first power consumption can be greater than the second power consumption, the first power can be greater than the second power, and the first encoding number can be greater than the second encoding number, without limitation.
[0178] It should be noted that the above constraint condition is only an example, and the first bandwidth, the second bandwidth, the first port number, the second port number, the first power consumption, the second power consumption, the first power, the second power, the first encoding number, and the second encoding number can also be established without the constraint condition, without limitation.
[0179] It can be understood that the first measurement area and the second measurement area can be a set of areas and can include one or more areas, without limitation. For example, as shown in FIG. 8, the horizontal axis is time (t) and the vertical axis is frequency (f), where measurement area #1, measurement area #2, measurement area #3, and measurement area #4 can be the above measurement areas; measurement area #1 and measurement area #2 can be the first measurement area for regular measurement; and measurement area #3 and measurement area #4 can be the second measurement area for burst measurement. In this way, the first device can meet most of the regular measurement requirements through the first measurement area and meet the burst measurement requirements through the second measurement area, to maintain sufficient measurement flexibility.
[0180] Based on the above introduction, the implementation process of the first device obtaining the measurement area will be specifically introduced below.
[0181] Case 1: The first device can be determined by receiving configuration information.
[0182] In case 1, the first device can determine the measurement region, i.e., the display indication, by receiving the configuration information (including the information of the measurement region) from other devices, such as the following second device. For example, taking the first device as a terminal device and the second device as a network device, the first measurement region can be configured by the second device, i.e., the second device can send the configuration information #1 to the first device, and the configuration information #1 can include the first measurement region, such as the measurement region #1 and the measurement region #2 shown in FIG. 8, to meet the regular measurement requirement; or the first device can request the second device to configure, i.e., the second device can send the configuration information #2 to the first device, and the configuration information #2 can include the second measurement region, such as the measurement region #3 and the measurement region #4 shown in FIG. 8; then, the second device can dynamically activate the measurement region #3 and / or the measurement region #4 by the indication information, such as the indication information #b, to meet the burst measurement requirement.
[0183] Case 2: The measurement region can be predefined or preconfigured.
[0184] Case 3: The configuration parameters of the measurement region are determined according to at least one reference signal or at least one measurement function.
[0185] In case 3, the first device can determine the configuration parameters of the measurement region according to at least one reference signal or at least one measurement function, i.e., the implicit indication, so that the signaling related to the configuration of the measurement region is not needed to be sent to indicate, thereby saving the overhead. Different reference signals or different measurement functions correspond to different configuration parameters of the measurement region, so that the measurement region can be dynamically changed according to the different reference signals or measurement functions to meet the requirements of different scenarios.
[0186] For example, according to the above introduction, any one of the at least one reference signal can be associated with a physical channel, so that the first device can determine the configuration parameters of the measurement region according to the physical channel associated with each reference signal, i.e., the first device can determine the configuration parameters of the measurement region corresponding to the reference signal #1 according to the configuration parameters of the channel #1 associated with the reference signal #1; or according to the above introduction, any one of the at least one reference signal can be used for the measurement of one or more measurement functions, so that the first device can determine the configuration parameters of the measurement region corresponding to the reference signal #1 according to the measurement function or the measurement purpose corresponding to the reference signal #1, such as the cell measurement, the channel measurement, or the beam measurement; or the first device can directly determine the configuration parameters of the measurement region according to the at least one measurement function.
[0187] The frequency domain parameters of the measurement region are taken as an example for introduction.
[0188] Optionally, the bandwidth of the measurement region can be determined according to at least one of the bandwidth of the first device, the bandwidth of the physical channel, or the bandwidth of the reference signal.
[0189] It can be understood that the bandwidth of the first device can dynamically change. For example, when the first device is establishing a connection using a network, the available bandwidth of the first device can be adjusted in real time according to the network environment, data traffic demand, quality of service settings, network management policies, and the like, to meet the needs of different services and scenarios. At this time, the bandwidth of the measurement region can dynamically change with the change in the bandwidth of the first device.
[0190] The bandwidth of the measurement region can also be determined according to the bandwidth of the physical channel. For example, taking reference signal #1 as an example, the reference signal #1 can be carried on a PDSCH, a PDCCH, a PUCCH, a PUSCH, or a PRACH, and the like. At this time, the first device can determine the bandwidth corresponding to the PDSCH, the PDCCH, the PUCCH, the PUSCH, or the PRACH, and the like, as the bandwidth of the measurement region corresponding to the reference signal #1.
[0191] The bandwidth of the measurement region can also be directly determined according to the bandwidth of the reference signal. For example, taking reference signal #1 and reference signal #2 as an example, the bandwidth of the reference signal #1 can be bandwidth #a, and the bandwidth of the reference signal #1 can be bandwidth #b. At this time, the first device can determine bandwidth #a as the bandwidth of the measurement region corresponding to the reference signal #1, and determine bandwidth #b as the bandwidth of the measurement region corresponding to the reference signal #2.
[0192] For example, as shown in FIG. 9, taking a first device as a UE and a second device as a gNB as an example, it is assumed that the bandwidth of the gNB is B1, the bandwidth of the UE at T1 is B2, the bandwidth of the UE at T2 is B3, the bandwidth of the UE at T3 is B4, the bandwidth of the UE at T4 is B5, the bandwidth of the UE at T5 is B6, the bandwidth of the UE at T6 is B7, and the bandwidth of the PDSCH at T1 is B8.
[0193] At T1, assuming that the CSI-RS is associated with the PDSCH, the UE can determine that the bandwidth of the measurement region corresponding to the CSI-RS is equal to the bandwidth B8 of the PDSCH; at T2, the cell measurement can be associated with the bandwidth of the UE, and the UE can determine that the bandwidth of the measurement region corresponding to the cell measurement is equal to the current bandwidth B3 of the UE, and so on. It can be understood that B1=B2+B3+B4+B5+B6+B7, that is, the UE can implement frequency hopping at T1-T6 to improve the security of communication. Meanwhile, taking the cell measurement as an example, the UE can use B2 for cell measurement at T1, use B3 for cell measurement at T2, use B4 for cell measurement at T3, use B5 for cell measurement at T4, use B6 for cell measurement at T5, and use B7 for cell measurement at T6, so that the UE can obtain the cell measurement result of the full bandwidth in combination with the cell measurement results at T1-T6.
[0194] Assuming that the first device works in the energy saving mode, for example, the first device is in the working state (measurement and communication) only in the measurement region, and is in the sleep state outside the measurement region, at this time, the first device can also determine the minimum value of the bandwidth of the physical channel and the bandwidth of the UE as the bandwidth of the measurement region, to further reduce the power consumption of the first device and improve the energy saving effect. For example, as shown in FIG. 9, at T1, the bandwidth of the measurement region corresponding to the CSI-RS can be min(B2, B8).
[0195] It can be understood that the determination manner of other configuration parameters of the measurement region, such as the time domain configuration parameter, the space domain configuration parameter, the code domain configuration parameter, and the power domain configuration parameter, is similar to the determination manner of the bandwidth of the measurement region, which can be understood with reference, and will not be described herein. Taking the cell measurement and the channel measurement as examples, the determination of the time domain configuration parameter, the frequency domain configuration parameter, and the space domain configuration parameter of the measurement region will be introduced below.
[0196] For example, for the channel measurement, the configuration parameter of the measurement region can be determined according to the reference signal or the physical channel, such as the rank index (RI), the precoding matrix index (PMI), and the channel quality indicator (CQI) measurement, the time domain of the measurement region can be determined by the service frequency carried by the data channel, the frequency domain bandwidth can be the same as the data channel, and the space domain can be determined by the data rate. For another example, for the cell measurement, the configuration parameter of the measurement region can be determined by the number of associated cells and the service area configuration, such as the RRM measurement, the time domain of the measurement region can be determined by the moving speed of the first device and the number of adjacent areas, the frequency domain bandwidth can be the same as the SSB, and the space domain can be a single port or determined according to the low complexity precoding, without limitation.
[0197] It can be understood that the above case 3 is introduced by taking the configuration parameter of the measurement area as an example, which is determined according to at least one reference signal or at least one measurement function. The configuration parameter of the measurement area can also be pre-configured, pre-defined, or explicitly indicated. For example, the second device can send the configuration parameter of the measurement area to the first device through indication information or configuration information, and the like, without limitation.
[0198] It can be understood that the above naming of the measurement area is only an example, and the measurement area can also be replaced by any other possible naming, such as a measurement basic unit, without limitation. The above naming of the reference signal is only an example, and the reference signal can also be replaced by any other possible naming, such as a measurement signal, signal #1, and the like, without limitation.
[0199] For the above step S602:
[0200] The measurement area can be used for the first device to measure at least one reference signal and / or measure at least one measurement function only in the measurement area, and any one of the at least one reference signal is used for measurement of one or more measurement functions. The measurement area can also be used for the second device to send at least one reference signal and / or receive measurement results of the at least one reference signal in the measurement area, without limitation.
[0201] It can be understood that the second device can obtain the measurement area through pre-definition or pre-configuration, or from other network functions, without limitation. After the second device obtains the measurement area, the second device can notify the first device of the measurement area. For example, the second device can send configuration information to the second device, and the configuration information can include information of the measurement area, that is, corresponding to the above case 1. It can be understood that the above step S602 is an optional step, that is, the second device can also not need to obtain the measurement area, and the present application embodiment does not limit this.
[0202] For the above step S603:
[0203] After the second device obtains the measurement region, the second device can send the first reference signal to the first device in the measurement region, and the first device can receive the first reference signal from the second device in the measurement region (i.e., step S604). The at least one reference signal can include the first reference signal. The first reference signal can be any one of a CSI-RS, an SSB, a PSS, an SSS, a TRS, a PTRS, a DMRS, a CRS, a PSS, or an SRS, without limitation. For example, as shown in FIG. 7, the first reference signal can be any one of an SSB, a TRS, or a CSI-RS. For ease of understanding, the embodiments of the present application take the first reference signal as a CSI-RS for subsequent introduction. The second device can send the CSI-RS to the first device in the measurement region, and the first device can receive the CSI-RS from the second device in the measurement region.
[0204] For step S604 described above:
[0205] In a possible design, the first device receives the first reference signal from the second device in the measurement region, and / or sends a measurement result corresponding to the first reference signal to the second device in the measurement region. Correspondingly, the second device receives the measurement result corresponding to the first reference signal from the first device in the measurement region.
[0206] The measurement result corresponding to the first reference signal can include at least one of a CSI, a PMI, a CQI, an RI, a layer indicator (LI), a reference signal receiver power (RSRP), a reference signal receiver quality (RSRQ), a reference signal receiver indicator (RSSI), a signal to interference noise ratio (SINR), a beam quality, a cell quality, a CSI-RS resource indicator (CRI), a L1-RSRP, a L1-RSRQ, etc., without limitation. After the first device obtains the measurement result corresponding to the first reference signal, the first device can send the measurement result corresponding to the first reference signal to the second device in the measurement region.
[0207] The measurement result corresponding to the first reference signal can be carried in at least one of the following: PUCCH, PUSCH, RRC signaling, medium access control-control element (MAC-CE) signaling, or DCI, etc., that is, carried in an existing information element to reduce the difficulty of implementation, or can be carried in a new information element to improve the flexibility of implementation, without limitation. It can be understood that the present application embodiment does not limit the specific implementation of the first device receiving and measuring the first reference signal, and the reporting of the measurement result corresponding to the first reference signal.
[0208] In summary, the first device can only measure the at least one reference signal and / or measure the at least one measurement function in the measurement area, and does not measure the at least one reference signal and / or measure the at least one measurement function outside the measurement area. In this way, the at least one reference signal or the at least one measurement function can be measured in the measurement area, thereby avoiding the problem that the at least one reference signal or the at least one measurement function needs to be measured on different resources, and the first device is always woken up for measurement, thereby reducing the power consumption of the first device (which can be a terminal device).
[0209] In combination with the above embodiments, in a possible design, the above method can further include:
[0210] The first device communicates in the measurement area.
[0211] That is, the first device can measure the at least one reference signal and / or measure the at least one measurement function in the measurement area, and can also communicate, such as transmitting control information, data, etc., without limitation. In this way, resource multiplexing can be achieved to provide resource utilization. Further, the first device can also enter a sleep or hibernate state outside the measurement area, so that the measurement and communication of the first device are only performed in the measurement area. The measurement area can also be a range of areas for limiting communication behavior, and at this time, the measurement area can also have another name, so the measurement area can also be referred to as a first area, etc. In this way, performance and power saving can be compromised, more sleep can be achieved, and energy efficiency can be effectively improved to save power consumption.
[0212] It can be understood that the same features in the above steps S601-S604, such as the measurement area, the at least one reference signal, the at least one measurement function, etc., have the same meaning and can be understood with reference, without being repeated.
[0213] It can be understood that the above examples are introduced by taking the second device sending the first reference signal to the first device in the measurement area, the first device receiving the first reference signal from the second device in the measurement area as an example, assuming that the second device is a network device and the first device is a terminal device, the first reference signal can be a downlink reference signal; in addition, the first device can also send a second reference signal (such as at least one reference signal including the second reference signal) to the second device in the measurement area, and the second device can receive the second reference signal from the first device in the measurement area, assuming that the second device is a network device and the first device is a terminal device, the second reference signal can be an uplink reference signal; or the second device can send the first reference signal to the first device in the measurement area, and the first device can receive the first reference signal from the second device in the measurement area, at the same time, the first device can send the second reference signal (such as at least one reference signal including the second reference signal) to the second device in the measurement area, and the second device can receive the second reference signal from the first device in the measurement area (i.e. full duplex), assuming that the second device is a network device and the first device is a terminal device, the first reference signal can be a downlink reference signal, and the second reference signal can be an uplink reference signal, the implementation principle is similar to the above examples, which can be understood by reference, and will not be described here.
[0214] For example, FIG. 10 is a flow diagram of a communication method provided by the embodiment of the application. The communication method is applied to the communication between the first device and the second device in the above communication system.
[0215] Specifically, as shown in FIG. 10, the flow of the communication method is as follows:
[0216] S1001, the second device sends configuration information of the first reference signal to the first device. Correspondingly, the first device acquires the configuration information of the first reference signal.
[0217] S1002, the second device sends the first reference signal to the first device. Correspondingly, the first device acquires the first reference signal.
[0218] S1003, the second device measures according to the first reference signal.
[0219] The related contents in the above steps S1001-S1003 are described in detail below.
[0220] For the above step S1001:
[0221] The configuration information can include a first configuration and a second configuration, the first configuration can be used to indicate the first part, and the second configuration can be used to indicate the second part. The first part of the first reference signal can be used for a first measurement function, and the second part of the second reference signal can be used for a second measurement function. The first measurement function and the second measurement function can include at least one of the following: cell measurement, channel measurement, time-frequency measurement, phase measurement, beam measurement, TRP measurement, sensing measurement, AI measurement, timing advance measurement, or any other possible measurement function, without limitation.
[0222] The first part of the first reference signal can be a part of the first reference signal corresponding to the first resource, and the second part of the first reference signal can be a part of the first reference signal corresponding to the second resource. It can be understood that the first reference signal can occupy a resource, such as resource #1, for measurement. The resource #1 can be a resource composed of at least one of the time domain, the frequency domain, the spatial domain, the code domain, or the power domain, without limitation. Different resource parts of the resource #1 can be used for different measurement functions, such as a part of the first resource in the resource #1 for the first measurement function, and a part of the second resource in the resource #1 for the second measurement function. That is, the first device can multiplex different resource parts of the first reference signal for multiple measurement functions.
[0223] For example, taking resource #1 as a time-frequency resource (full bandwidth B1) and the first reference signal as RS#a as shown in FIG. 11, at t1, bandwidth B2 (B2 < B1) can be used for cell measurement, beam measurement, etc. Combining t1 and t2, bandwidth B2 can be used for time-frequency offset measurement, phase measurement, etc. At t1 or t2, bandwidth B1 can be used for full-band channel measurement, without limitation.
[0224] It should be noted that the first reference signal can multiplex an existing reference signal to reduce implementation difficulty, or a new reference signal can also be used to improve implementation flexibility, without limitation. The configuration information can be carried in at least one of the following: PUCCH, PUSCH, RRC signaling, medium access control-control element (MAC-CE) signaling, or DCI, that is, in an existing information element to reduce implementation difficulty, or in a new information element to improve implementation flexibility, without limitation.
[0225] It can be understood that the first device can also obtain the configuration information of the first reference signal in other manners, such as pre-configuration or pre-definition, without limitation. The naming of the above configuration information is only an example, and the measurement area can also be replaced by any other possible naming, such as resource configuration information, information #1, etc., without limitation; the naming of the above first reference signal is only an example, and the first reference signal can also be replaced by any other possible naming, such as measurement signal, signal #2, etc., without limitation.
[0226] For the above step S1002:
[0227] The second device can send the first reference signal to the first device, and correspondingly, the first device can receive the first reference signal from the second device, such as the above RS#a, and the implementation process of the embodiments of the present application is not limited.
[0228] For the above step S1003:
[0229] In a possible design, the second device sends the indication information to the first device. Correspondingly, the first device receives the indication information from the second device.
[0230] The first device measures the first reference signal using the first part of the first reference signal according to the indication information.
[0231] The indication information can be used to indicate the measurement of the first measurement function. That is, when the second device needs to obtain the measurement result corresponding to the first measurement function, the second device can activate the first configuration corresponding to the first measurement function through the indication information, that is, the part of the first reference signal corresponding to the first resource, and the first device can trigger the measurement of the first reference signal using the first part of the first reference signal according to the indication information and the configuration information to obtain the measurement result corresponding to the first measurement function, to realize on-demand indication and flexibility.
[0232] It can be understood that the first device can also use the corresponding part (such as the second part) to perform the measurement (such as the second measurement function) of the corresponding measurement function (such as the second measurement function) on the first reference signal according to the received indication information (such as indicating the measurement of the second measurement function) and the configuration information, and the implementation principle is similar and can be understood by reference, without repetition. Based on the above introduction, different measurement functions of the first reference signal can be activated semi-statically or dynamically activated and deactivated, and the implementation process can refer to the existing implementation, without repetition.
[0233] For example, continuing the above example, as shown in (a) of FIG. 12, the gNB can activate configuration #a, i.e., (t1, B2), by indicating information #a1, so that the UE can use the bandwidth B2 to perform cell measurement, beam measurement, etc. at time t1; as shown in (b) of FIG. 12, the gNB can activate configuration #2, i.e., (t1-t2, B2), by indicating information #a2, so that the UE can use the bandwidth B2 to perform time-frequency offset measurement, phase measurement, etc. at times t1 and t2; as shown in (c) of FIG. 12, the gNB can activate configuration #3, i.e., (t1, B1) or (t2, B1), by indicating information #a3, so that the UE can use the bandwidth B2 to perform full-band channel measurement, etc. at time t1 or t2, without limitation. When the gNB determines that the UE does not need to use the first reference signal for measurement, the gNB can also deactivate the information to deactivate (deactivate), and the implementation principle is similar, which can be understood by reference, and will not be described here.
[0234] After the first device measures the first reference signal using the first part of the first reference signal according to the indication information to obtain the first measurement result (which can be used to characterize the first measurement function), the first device can also send the first measurement result to the second device; similarly, the first device can also report the second measurement result (which can be used to characterize the second measurement function) obtained by measuring the first reference signal using the second part of the first reference signal to the second device, so that the second device can perform subsequent operations according to the measurement result, without limitation. It can be understood that the specific implementation of the first device receiving and measuring the first reference signal and reporting the measurement result corresponding to the first reference signal is not limited.
[0235] In summary, different parts of the first reference signal can be used for different measurement functions, or in other words, the first device can perform different measurement functions by multiplexing different parts of the first reference signal, such as different resources, so that resource consumption and power consumption of the first device can be reduced, and resource overhead can be saved.
[0236] It can be understood that the same features in the above steps S1001-S1003, such as the first reference signal, the configuration information of the first reference signal, the first configuration, the second configuration, the first part, the second part, the first measurement function, the second measurement function, etc. have the same meaning, which can be understood by reference, and will not be described here.
[0237] It can be understood that the above embodiments are introduced by taking the measurement area for measurement as an example. The measurement area can also be replaced by any other customizable area for performing corresponding functions, and the implementation principle is similar, which can be understood by reference, and will not be described in detail. For example, the measurement area can also be replaced by a sensing area (such as a sensing resource), that is, the first device can only perform centralized sensing in the sensing area, and for another example, the measurement area can also be replaced by an AI area (such as an AI resource), that is, the first device can only perform centralized AI measurement in the AI area, and the like, without limitation. Exemplarily, the implementation principle of the measurement area can also be applicable to a measurement window, for example, (1) the device only communicates in the measurement window and does not communicate outside the measurement window; (2) the device is only activated in the measurement window and sleeps outside the measurement window; (3) the measurement window can be activated by a wake-up signal or a low-power wake-up signal (such as a power consumption less than a preset value), and the like, without limitation.
[0238] The communication method provided by the embodiments of the present application is described in detail above in combination with FIGS. 6-12.
