In the technical solution proposed in this application, the network device configures a low-power partial bandwidth for the terminal device. When the cell is in a dormant state, the terminal device can use the low-power partial bandwidth for signal synchronization. Compared with using the dormant partial bandwidth for channel state information measurement, this can reduce the resource consumption of the cell in the dormant state.

Description

Technical Field

[0001] This application relates to the field of communications, and more particularly to communication methods and communication devices. Background Technology

[0002] In wireless communication networks, to reduce energy consumption, the system activates and deactivates cells based on their service demands, channel conditions, and load. Deactivated cells do not handle information transmission, thus reducing energy consumption. However, the transition from deactivated to activated states involves a significant delay.

[0003] To reduce the latency of switching a network cell from deactivated to active state, it enters a dormant state when there is no service data. While in dormant state, terminal equipment does not detect downlink control channels, perform random access, or transmit uplink data; it only performs channel state information reference signal (CSI-RS) measurements and beam management.

[0004] However, even when the network cell is in a dormant state, the communication system still suffers from high energy consumption. Summary of the Invention

[0005] The communication method and communication device provided in this application help to further reduce the energy consumption of communication systems.

[0006] In a first aspect, this application provides a communication method. This communication method can be executed by a communication device, or by a chip, chip system, processor, processor system, circuit unit, or circuit system configured for use in a communication device. For ease of description, the following description in this aspect will use a communication device as an example. For example, the communication device can be an access network device. For ease of description, in this application, the communication device is referred to as a network device, and the communication device at the other end is referred to as a terminal device.

[0007] This communication method includes: sending first information, the first information indicating configuration parameters of a sleep portion bandwidth, the configuration parameters of the sleep portion bandwidth including at least one of the following parameters: maximum power, maximum bandwidth, or, maximum modulation and coding strategy; sending second information, the second information indicating configuration parameters of a first portion bandwidth, the configuration parameters of the first portion bandwidth including at least one of the above parameters, wherein at least one parameter of the first portion bandwidth is less than at least one parameter of the sleep portion bandwidth.

[0008] It is understandable that the dormant bandwidth part (dormant-BWP) is a bandwidth configuration that allows a cell to enter a dormant state when there is no service data. In some implementations, in this state, the terminal does not detect the physical downlink control channel (PDCCH), does not access the physical random access channel (PRACH), and does not transmit uplink data; it only performs CSI-RS measurements and beam management.

[0009] In this application, the first part of the bandwidth can be referred to as the low power bandwidth part (LP-BWP).

[0010] In this application, at least one parameter of the first portion bandwidth is less than at least one parameter of the dormant portion bandwidth, which can be understood as: the value of one or more parameters of the maximum power, maximum bandwidth and maximum modulation and coding strategy of the first portion bandwidth is less than the value of the same parameter in the dormant portion bandwidth.

[0011] It's understandable that while a larger bandwidth can support higher transmission speeds, it requires higher transmission power, increasing energy consumption. Therefore, the maximum bandwidth of the first bandwidth portion is smaller than the maximum bandwidth of the sleep bandwidth portion, which helps the terminal reduce power consumption when operating in the first bandwidth portion.

[0012] A higher modulation scheme requires a higher signal-to-noise ratio, necessitates higher transmit power, and increases energy consumption. Therefore, a maximum modulation and coding scheme in the first bandwidth portion is smaller than that in the sleep bandwidth portion, which helps the terminal reduce power consumption when operating in the first bandwidth portion.

[0013] The maximum power of the first bandwidth section is less than the maximum power of the sleep bandwidth section, which helps the terminal reduce power consumption when operating in the first bandwidth section.

[0014] It can be understood that the dormant bandwidth and the first bandwidth constitute a portion of the cell's bandwidth. For example, the dormant bandwidth and the first bandwidth constitute a portion of the secondary cell's bandwidth. In some scenarios, the secondary cell can also be referred to as a secondary carrier.

[0015] In one possible design, the configuration parameters for the first portion of the bandwidth do not include configuration parameters for at least one of the following: channel state information reference signal resources, physical random access channels, control resource sets, or search space.

[0016] In this method, LP-BWP does not contain configuration information for at least one of the following: CSI-RS, PRACH, control resource set (CORESET), or search space. That is, LP-BWP resources do not undertake the work corresponding to at least one of the above configuration information, which can reduce resource consumption when LP-BWP is working.

[0017] In one possible design, the configuration parameters for the first portion of the bandwidth include the configuration parameters for the low-power synchronization signal.

[0018] As can be understood, a low-power synchronization signal (LP-SS) is a synchronization signal used for low-power operation. LP-SS can provide synchronization information to terminal devices in low-power mode.

[0019] In this design, by configuring LP-SS on the first part of the bandwidth for radio resource management (RRM) measurements, less resources are consumed to complete the channel state measurement compared to configuring CSI-RS resources for CSI measurements.

[0020] In one possible design, the configuration parameters of the low-power synchronization signal include at least one of the following parameters: periodicity, time-domain position, frequency-domain position, number of beams, transmit power, or signal waveform.

[0021] For example, the periodicity of the low-power synchronization signal includes periodic transmission of the LP-SS, semi-periodic transmission, or aperiodic resource transmission, indicated by downlink control information (DCI). The time-domain location includes the start time of the LP-SS transmission; if the LP-SS is an aperiodic resource, the end time and the number of symbols occupied in the time domain must also be indicated. The frequency-domain location of the LP-SS can be the size of the resource block (RB) occupied by the LP-SS.

[0022] For example, the number of beams in an LP-SS includes 2, 4, or 8, and the signal waveform used by the LP-SS includes on-off keying (OOK) 1 or OOK 2.

[0023] As you can understand, OOK is a digital modulation technique commonly used in wireless communication systems. OOK modulation represents binary data by switching a carrier signal on and off. For example, when a binary "1" is sent, the presence of the carrier signal indicates that the signal is on; when a binary "0" is sent, the absence of the carrier signal indicates that the signal is off.

[0024] In this design, the LP-SS is configured by configuring at least one of the following parameters: periodicity, time-domain position, frequency-domain position, number of beams, transmit power, or signal waveform. This enables the terminal device to perform RRM measurements using the LP-SS based on the configuration information.

[0025] In one possible design, the method further includes: the terminal device detecting the channel state information reference signal and performing beam management on the first portion of the bandwidth.

[0026] It is understandable that beam management includes beam scanning, beam measurement, beam identification, beam reporting, and beam fault recovery, enabling the network to flexibly adapt to different user needs and environmental conditions.

[0027] In this design, the LP-BWP can detect CSI-RS signals and perform beam management. Compared to detecting LP-SS, it can achieve more detailed channel state information measurement. Moreover, because the LP-BWP is designed to operate at low power, it can still save resources compared to the Dormant-BWP.

[0028] In one possible design, the method further includes sending a third message, which is used to activate the dormant portion of the bandwidth and / or the first portion of the bandwidth.

[0029] This design instructs terminal devices to activate Dormant-BWP and LP-BWP via network devices. This allows for flexible use of BWPs based on actual usage scenarios. For example, Dormant-BWP can be used when there is a high demand for terminal devices to resume data transmission from sleep mode, while LP-BWP can be used when low power consumption is a priority. This provides a low-power solution while maintaining performance in certain scenarios. Furthermore, network devices can instruct terminal devices to activate both Dormant-BWP and LP-BWP simultaneously, reducing latency when switching from sleep to active mode while also reducing power consumption during sleep mode.

[0030] In one possible design, the method further includes: sending fourth information, the fourth information being used to indicate a first state of the first portion of the bandwidth and / or a second state of the sleep portion of the bandwidth, the first state including detecting a low-power synchronization signal or detecting a channel state information reference signal, and the second state including not detecting a channel state information reference signal.

[0031] In this design, CSI-RS or LP-SS measurements are performed using LP-BWP, which consumes fewer resources to complete channel measurements compared to using Dormant-BWP.

[0032] Secondly, this application provides a communication method that can be executed by a communication device, or by a chip, chip system, processor, processor system, circuit unit, or circuit system configured for use in a communication device.

[0034] In one possible design, the configuration parameters for the first portion of the bandwidth do not include configuration parameters for at least one of the following: channel state information reference signal resources, physical random access channels, control resource sets, or search space.

AI network elements can also be referred to as AI nodes, AI devices, AI entities, AI modules, AI models, or AI units, etc. The AI ​​network elements may be built into the network elements of the communication system. For example, an AI network element may be an AI module built into: access network equipment, core network equipment, cloud servers, or operation, administration, and maintenance (OAM) systems to implement AI-related functions. The OAM system may act as the network management system for core network equipment and / or access network equipment. Alternatively, the AI ​​network element may be an independently configured network element within the communication system. Optionally, the terminal or its built-in chip may also include an AI entity to implement AI-related functions.

[0086] RAN 100 includes at least one radio access network device (such as...) Figure 1 110a and 110b (collectively referred to as 110) and at least one terminal (such as Figure 1 RAN 100, denoted as RAN 120a to 120j, is collectively referred to as RAN 120. RAN 100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure 1 (Not shown in the image). Terminal 120 is connected to wireless access network device 110 wirelessly. Wireless access network device 110 is connected to core network 200 wirelessly or via wired connection.

[0087] The core network equipment in the core network 200 and the radio access network equipment 110 in the RAN 100 can be different physical devices, or they can be the same physical device that integrates core network logical functions and radio access network logical functions.

[0088] RAN 100 can be a 3GPP-related cellular system, such as a 4th generation (4G) mobile communication system, like LTE; a 5G mobile communication system, like NR and NTN; and a communication system evolving after 5G, such as Future Mobile Communications System (MWC). It can also be a wireless fidelity (WiFi) system, a vehicle-to-everything (V2X) communication system, a device-to-everything (D2D) communication system, or a vehicle-to-everything (V2X) communication system. RAN 100 can also be an open radio access network (O-RAN or ORAN), a cloud radio access network (CRAN), or a WiFi system. RAN 100 can also be a communication system that integrates two or more of the above systems.

[0089] Understandable. Figure 1 This application only illustrates one possible communication system architecture that can be applied to an embodiment of the present application. In other possible scenarios, the communication system architecture may also include other devices.

[0090] The radio access network device 110 is a node in the RAN, also known as an access network device or an RAN node (or device). The radio access network device 110 is used to help terminals achieve wireless access. Multiple radio access network devices 110 in a communication system can be nodes of the same type or different types.

[0091] In some scenarios, the roles of wireless access network device 110 and terminal 120 are relative, for example, Figure 1 The network element 120i can be a helicopter or a drone, and it can be configured as a mobile base station. For terminals 120j that access RAN 100 through network element 120i, network element 120i is a base station; however, for base station 110a, network element 120i is a terminal. Both the wireless access network device 110 and the terminal 120 are sometimes referred to as communication devices, for example... Figure 1 Network elements 110a and 110b can be understood as communication devices with base station functions, while network elements 120a to 120j can be understood as communication devices with terminal functions.

[0092] In one possible scenario, wireless access network equipment 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 base station in a future mobile communication system, a satellite, or an access point (AP) in a WiFi system, such as a home gateway, router, server, switch, bridge, etc. It can also be an integrated access and backhaul (IAB) node, or a wireless access network device in a mobile switching center (NTN) communication system, meaning it can be deployed on high-altitude platforms or satellites. Wireless access network equipment can also be a macro base station (such as...) Figure 1 110a), micro base stations or indoor stations (such as Figure 1 The wireless access network equipment can be a satellite in a satellite communication system, or a base station device mounted on a satellite. It can also function as a base station in D2D communication, vehicle-to-everything (V2X) communication, drone communication, or machine-to-machine (M2M) communication. Optionally, it can also be a server, wearable device, vehicle, or in-vehicle equipment. For example, in V2X technology, the access network equipment can be a roadside unit (RSU).

[0093] In some possible scenarios, multiple radio access network (RAN) devices collaborate to assist a terminal in achieving wireless access, with each RAN device performing some of the functions of a base station. In this scenario, as an example, the RAN devices can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc.

[0094] CU and DU can be configured separately or included in the same network element, such as in a baseband unit (BBU). RU can be included in radio frequency equipment or radio frequency units, such as in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0095] It is understood that in the description of the following embodiments, the radio access network device can be a CU node, a DU node, or a device including both CU nodes and DU nodes. Furthermore, a CU can be classified as a network device in the access network (RAN) or as a network device in the core network (CN), and no limitation is imposed here.

[0096] In some implementations, the CU performs some of the functions of layer 2 (L2) and layer 3 (L3), the DU performs some of the functions of layer 1 (L1) and L2, and the RU performs the computation of L1 and the digital part of RF.

[0097] The midhaul interface carries traffic between the CU and DU, the backhaul interface carries traffic between the CU and CN, and the fronthaul interface carries traffic between the RU and DU. The integrated DU includes the functions of both the DU and RU mentioned above.

[0098] The CU and / or DU include processors and hardware accelerators. The processors may include x86 processors or non-x86 processors, and the hardware accelerators may include FPGAs, GPUs, or other accelerators.

[0099] Taking DU as an example, DU can be implemented using a multi-core processor and one or more hardware accelerators. Parts of the DU protocol stack can be implemented in software running on a multi-core processor, while computationally intensive L1 and L2 functions can be offloaded to FPGA- or GPU-based hardware accelerators; or all L1 functions can be offloaded to FPGA- or GPU-based hardware accelerators, while other protocol stack components are implemented in software running on the processor; or the entire protocol stack can be implemented in software running on the processor. The hardware accelerator supports interconnection with x86 or non-x86 processors. Similarly, the accelerator has a multi-channel PCIe interface pointing to the CPU and external connections via GbE.

[0100] An RU can include three parts: an O-RAN processing unit (OPU), an O-RU digital processing unit (DPU), and a radio frequency (RF) processing unit.

[0101] The OPU receives eCPRI frames from the O-RAN fronthaul and performs fronthaul interface, lowest-level L1 (encoding, scrambling, modulation, layer mapping, precoding), synchronization, beamforming, and resource unit mapping. The OPU can be a CPU, FPGA, or ASIC.

[0102] The DPU can perform synchronous, DDC (digital downconversion in UL), and DUC (digital upconversion in DL) operations, improving power amplifier efficiency by reducing PAPR / ACLR at the RF front end; the DPU can be an FPGA or an ASIC.

[0103] The RF processing unit may include a transceiver module, up / down converters, power amplifiers (PAs), low-noise amplifiers (LNAs), and Tx / Rx filters. All conversions between the analog and digital domains (DAC and ADC), such as RF sampling, frequency conversion using RF, IF, and LO mixing during up-conversion and down-conversion, are performed within the transceiver module. In some implementations, the physical and logical partitions within the RF processing unit do not require specific boundaries.

[0104] In some implementations, the radio access network may include a non-real-time RAN intelligent controller (Non-RT RIC), a near-real-time RAN intelligent controller (Near-RT RIC), an O-RAN central unit control plane (O-CU-CP), an O-RAN central unit user plane (O-CU-UP), an O-RAN distributed unit (O-DU), and an O-RAN radio unit (O-RU). The O-CU-CP and O-CU-UP together can be referred to as the O-RAN central unit (O-CU). These can all be considered radio access network devices.

[0105] The Near-RT RAN Intelligent Controller is used to implement non-real-time intelligent management of RAN functions, enabling AI / ML workflows including model training and model updates, and guiding applications / functions in the Near-RT RIC based on policies.

[0106] The near real-time RAN intelligent controller is used to realize near real-time intelligent management of the RAN. It can achieve near real-time control and optimization of O-RAN modules and resources through data collection and related operations on the E2 interface.

The super BS can take various forms, such as satellite, airborne balloon station, or drone station. Figure 2 The ground station can be any of the current cellular sites (macro stations, small stations, micro stations, etc.).

[0123] Figure 3 This is a schematic diagram illustrating an application scenario of one embodiment of this application. Figure 3 (a) in the diagram represents a single-connection scenario, in which the terminal connects to a single base station, and both the base station and the core network to which the base station connects are of the same standard. For example, the core network is a 5G core network, the corresponding base station is a 5G base station, and the 5G base station is directly connected to the 5G core network; or, the core network is a new standard core network, the corresponding base station is a new standard base station, and the new standard base station is directly connected to the new standard core network.

[0124] Figure 3(b) in the diagram represents a dual connectivity (DC) scenario, in which the terminal simultaneously connects to base stations of different or the same standard, applicable to terminals in connected mode. For example, if the core network is a 5G core network, the terminal connects simultaneously to both a 5G base station and a base station of the new standard, with the 5G base station acting as the primary station and the new standard base station as the secondary station. Another example is a core network of the new standard, where the terminal connects simultaneously to both a base station of the new standard and a 5G base station, with the new standard base station acting as the primary station and the 5G base station as the secondary station. Yet another example is a core network of the new standard, where the terminal connects simultaneously to two base stations of the new standard, meaning both the primary and secondary stations are base stations of the new standard.

[0125] It is understood that the network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0126] To meet the ever-increasing demand for data traffic, wireless networks are being rapidly deployed. As the network scales up, energy consumption continues to increase, significantly raising electricity costs for operators.

[0127] Besides the significant increase in costs for operators due to increased energy consumption, energy conservation and emission reduction are also a social responsibility for operators, requiring compliance with government regulatory requirements. Therefore, network-side energy conservation is a continuous area for optimization research, both in current and next-generation wireless communication systems.

[0128] In the current network, different equipment manufacturers and operators have adopted various energy-saving methods. For example, the current overall 5G energy-saving technology system includes equipment-level, site-level, and network-level energy saving. Among them, the equipment-level focuses on hardware energy-saving solutions researched from the perspective of device and hardware design; the site-level mainly focuses on software energy-saving solutions researched from the aspects of symbol shutdown, channel shutdown, carrier shutdown, and deep sleep; and the network-level energy-saving terminal performs intelligent energy saving from the perspective of multi-network coordination.

[0129] On the other hand, in addition to the increasing attention and research on network-side energy consumption, research on reducing terminal-side energy consumption continues in the evolution of NR systems. This includes technologies such as discontinuous reception (DRX) and BWP adaptation as defined in 3GPP Rel-15; cross-slot scheduling and PDCCH-based wake-up signal (WUS) as defined in Rel-16; paging early indication (PEI) and PDCCH monitoring adaptation as defined in Rel-17; and low-power reception and low-power wake-up signals to be supported in Rel-18 / 19.

[0130] To reduce energy consumption, existing technologies employ methods for activating and deactivating secondary cells to ensure efficient utilization of network resources and optimized performance of user equipment. When the amount of data transmitted or received is low, the terminal buffer is low, or the uplink / downlink channel quality of the carrier is poor, the secondary cell is deactivated. After deactivation, the UE will no longer transmit or receive data on the secondary cell, reducing energy consumption when there is no service. When the amount of data transmitted or received reaches the required level, or the terminal buffer status report (BSR) meets the requirements, the secondary cell is activated. After activation, the UE can transmit and receive data on the secondary cell, thus restoring the function of service transmission.

[0131] However, the existing methods described above still have some problems. The time delay required for a cell to switch from a deactivated state to an active state is relatively large. Therefore, the communications field has proposed a method where, when a cell has no service transmission needs, the DCI instructs the cell to enter a dormant state. In this state, the secondary component carrier (SCC) operates on the Dormant-BWP. In this state, the terminal does not detect the PDCCH, perform PRACH access, or send uplink data; it only performs CSI-RS measurements and beam management. This method of maintaining CSI-RS measurements and beam management even in the dormant state can reduce the time required to re-transmit data on the cell.

[0132] like Figure 4This is a schematic diagram of a dynamic bandwidth management mechanism method according to this application. When the BWP is in an active state, it can be switched from an active BWP to a dormant BWP by instructing the terminal device through DCI or an idle timer. The network device can instruct the terminal device's BWP to switch from an active state to a deactivated state through the Medium Access Control Element (MAC CE), or instruct the terminal device's BWP to switch from a deactivated state to an active state through the MAC CE / secondary cell deactivation timer.

[0133] As will be understood by those skilled in the art, CSI-RS is a signal used to measure the state of a wireless channel and provide feedback for base station scheduling. It enables the base station to understand the channel quality from the user equipment's perspective and to perform effective channel scheduling, link adaptation, beam management, and other operations accordingly, thus helping to re-establish the connection between terminal equipment and network equipment.

[0134] However, the above methods still require CSI-RS measurements and beam management for SCCs in dormant state, resulting in high energy consumption. To address this, this application provides a method that defines a new BWP type. Compared to DormantBWP, this BWP type can consume fewer resources to complete channel measurement, saving energy consumption of the cell in dormant state.

[0135] Figure 5 This is a flowchart of a communication method according to an embodiment of this application, including S501 and S502. The method is performed by communication between a network device and a terminal.

[0136] S501, the network device sends first information, which indicates the configuration parameters of the sleep portion bandwidth. The configuration parameters of the sleep portion bandwidth include at least one of the following parameters: maximum power, maximum bandwidth, or maximum modulation and coding strategy. Correspondingly, the terminal device receives the first information.

[0137] It is understandable that in some scenarios, the configuration parameters for the hibernation bandwidth may include, in addition to the parameters mentioned above, parameters such as the Dormant-BWP identifier, subcarrier spacing, cyclic prefix (CP) length, time-frequency domain position, and bandwidth size.

[0138] S502, the network device sends second information, which indicates the configuration parameters of the first portion of the bandwidth. The configuration parameters of the first portion of the bandwidth include at least one of the aforementioned parameters, wherein at least one parameter of the first portion of the bandwidth is less than at least one parameter of the hibernation portion of the bandwidth. Correspondingly, the terminal device receives the second information.

[0139] In this application, the first part of the bandwidth can also be referred to as low-power bandwidth (LP-BWP), and this application does not limit it.

[0140] It's understandable that larger bandwidth supports higher transmission speeds, which in turn requires higher transmit power and increases energy consumption. Modulation and coding strategies define a set of standards for the number of effective bits that each resource element (RE) can carry. Modulation schemes include BPSK, QPSK, 16QAM, 64QAM, and 256QAM, among others. These higher-order modulation formats can carry more information bits; however, they also require higher signal-to-noise ratios and higher transmit power, further increasing energy consumption.

[0141] For example, the maximum power of the LP-BWP is less than the maximum power of the Dormant-BWP, the maximum bandwidth of the LP-BWP is less than the maximum bandwidth of the Dormant-BWP, or the maximum modulation and coding strategy of the LP-BWP is less than the maximum modulation and coding strategy of the Dormant-BWP.

[0142] In some implementations, LP-BWP operates on a low-power receiver (LR).

[0143] In some implementations, Dormant-BWP operates on the main receiver (MR).

[0144] LP-BWP associated user capabilities can be applied to devices with lower hardware levels. The device parameters include at least one of the following: the number of LP-BWP transmit antennas and receive antennas is greater than or equal to 1, the number of LP-BWP radio frequency channels (RFchain) is greater than or equal to 1, the LP-BWP bandwidth is greater than or equal to 5MHz, and the signals that the LP-BWP receiver can detect include OOK signals or narrowband ODDM signals.

[0145] In some implementations, the configuration parameters for the first part of the bandwidth do not include configuration parameters for at least one of the following: channel state information reference signal resources, physical random access channels, control resource sets, or search space.

[0146] Understandably, to improve resource utilization and reduce blind detection complexity, the PDCCH no longer occupies the entire frequency domain bandwidth like in LTE; instead, it only occupies a portion of the frequency domain bandwidth, called the BWP, and each BWP has its own independent PDCCH channel. Furthermore, to increase system flexibility and adapt to different scenarios, the starting position of the PDCCH in the time domain is configurable. Therefore, in 5G NR, the UE needs to obtain or spatially search for the complete time and frequency domain resource configuration information of the PDCCH beforehand in order to further demodulate the content of the PDCCH channel.

[0147] For example, when a cell enters LP-BWP operation from a dormant state, it will not perform channel state information reference signal detection, will not use physical random access channels, or will not search the time-frequency domain space, including the control resource set.

[0148] In some implementations, the configuration parameters for the first part of the bandwidth include the configuration parameters for the low-power synchronization signal.

[0149] In some implementations, the configuration parameters of the low-power synchronization signal include at least one of the following parameters: periodicity, time-domain position, frequency-domain position, number of beams, transmit power, or signal waveform.

[0150] As can be understood, Low Power Synchronization Signal (LP-SS) is a synchronization signal used for low-power operation. LP-SS is designed to provide synchronization information to user equipment in low-power mode so that the UE can be quickly woken up and communication resumed when needed.

[0151] For example, the periodicity of the low-power synchronization signal includes periodic transmission of the LP-SS, semi-periodic transmission, or aperiodic resource transmission, indicated by the DCI. The time-domain location includes the start time of the LP-SS transmission; if the LP-SS is an aperiodic resource, the end time and the number of symbols occupied in the time domain are also required. The frequency-domain location of the LP-SS can be the size of the resource block (RB) occupied by the LP-SS.

[0152] For example, the number of beams in an LP-SS includes 2, 4, or 8, and the signal waveform used by the LP-SS includes on-off keying (OOK) 1 or on-off keying 2.

[0153] In this embodiment, after the network device configures a dormant bandwidth and a first bandwidth for the terminal device, the terminal device can activate the dormant bandwidth and / or the first bandwidth as needed. When the terminal device activates both the dormant bandwidth and the first bandwidth, it not only helps reduce the latency when the cell switches from a deactivated state to an active state, but also supports the terminal operating in the lower-power first bandwidth, thus helping to reduce the terminal's power consumption.

[0154] Optionally, this method may also include S503.

[0155] In S503, the network device sends a third message to activate the dormant portion of the bandwidth and the first portion of the bandwidth. Correspondingly, the terminal device receives the third message.

[0156] For example, when there is no service data transmission and the secondary cell needs to switch from active to deactivated state, the network device sends third information.

[0157] For example, the third information is DCI information.

[0158] Optionally, the third information can be used to instruct the terminal device to activate only Dormant-BWP, or it can be used by the network device to instruct the terminal device to activate only LP-BWP.

[0159] It is understandable that when a secondary cell needs to switch from a deactivated state to an activated state, the network device sends information to instruct the terminal device to deactivate the portion of bandwidth indicated by the third information.

[0160] For example, when the third information is used to activate the dormant bandwidth and the first bandwidth, if there is service data transmission, when the terminal switches to the active bandwidth, the network device sends information to instruct the terminal device to activate the dormant bandwidth and the first bandwidth.

[0161] Optionally, this method may also include S504.

[0162] S504, the network device sends fourth information, which indicates a first state of the first portion of the bandwidth and / or a second state of the sleep portion of the bandwidth. The first state includes detecting a low-power synchronization signal or detecting a channel state information reference signal, and the second state includes not detecting the channel state information reference signal. Correspondingly, the terminal device receives the fourth information.

[0163] For example, when Dormant-BWP and LP-BWP are activated simultaneously, MR and LR can exist in the following states:

[0164] Status A: The MR's dormant BWP is performing CSI measurements, while the LR's LP-BWP is not working.

[0165] Status B: The MR's dormant BWP does not perform CSI measurements, while the LR's LP-BWP detects CSI-RS and performs beam management.

[0166] Status C: MR's dormant BWP does not perform CSI measurement, LR's LP-BWP detects LP-SS and performs RRM measurement.

[0167] In State A, CSI measurements can be performed during cell sleep, enabling rapid cell wake-up. In State B, MR is not working, and LR performs CSI measurements, allowing for CSI measurements with lower power consumption. This enables CSI measurements to be performed in sleep mode on some low-performance devices, achieving rapid cell wake-up. In State C, MR is not working, and LR measures LP-SS and performs RRM measurements. Compared to State B, this allows for maintaining synchronization with network devices using lower power during sleep.

[0168] like Figure 6 This is a schematic diagram of another part of the bandwidth dynamic management mechanism method in this application. The LP-BWP is associated with the dormant BWP and can be activated and deactivated simultaneously. When the BWP is active, the terminal device can switch from activating the BWP to using the dormant BWP and LP-BWP via DCI or an idle timer. The network device can instruct the terminal device's BWP to switch from active to deactivated via MAC CE, or via MAC CE / secondary cell deactivation timer to switch the terminal device's BWP from deactivated to active.

[0169] In some implementations, the choice between state B or state C can be made based on the capabilities of LR.

[0170] For example, when the LR is an OOK receiver, the Dormant BWP is inactive, and the LP-BWP detects the LP-SS for periodic synchronization. When the LR is an OFDM receiver, the Dormant BWP is inactive, and the LP-BWP detects the CSI-RS and performs beam management. Because OOK modulation is typically used in low-power scenarios and does not require complex signal processing, it can handle LP-SS. However, OOK modulation usually does not provide sufficient modulation order to effectively transmit the complex information required by CSI-RS. CSI-RS signals require a higher modulation order to carry sufficient information; therefore, CSI-RS measurements are only performed when the LR is an OFDM receiver.

[0171] In some implementations, the terminal device proactively reports whether it is working on LP-BWP.

[0172] For example, if the terminal device is not operating on LP-BWP, it requests LP-SS resources sent on demand to achieve synchronization.

[0173] In some implementations, LP-SS measurements include LP-reference signal received power (RSRP) and / or LP-reference signal received quality (RSRQ).

[0174] In some implementations, cell signal quality is determined based on LP-SS measurement results.

[0175] For example, when the LP-RSRP / LP-RSRQ measured by LP-SS is less than a predefined threshold, the cell signal quality is determined to be poor; conversely, when the LP-RSRP / LP-RSRQ measured by LP-SS is greater than or equal to the predefined threshold, the cell signal quality is determined to be good.

[0176] In some implementations, LP-SS measurement parameters are configured based on the capabilities of LR.

[0177] For example, measurement parameters include the number of measurements, measurement cycle, number of reports, reporting interval, and reporting method.

[0178] In some implementations, the LP-BWP reports via an uplink wake-up signal (ULWUS), and the LP-SS measurement results can be reported after the measurement is completed, thus speeding up the acquisition of channel information.

[0179] In some implementations, the terminal reports measurement results via active-BWP.

[0180] For example, when the cell is woken up, the measurement results are reported through the physical uplink control channel (PUCCH) / physical uplink shared channel (PUSCH).
