[0041] Exemplarily, FIG. 1 is an architecture schematic diagram of a communication system provided by an embodiment of the present application. As shown in FIG. 1, the communication system 100 can include a network device 110, which can be a device that communicates with a terminal device 120 (or a communication terminal, a terminal).

In some embodiments of the present application, the communication system 100 can include multiple network devices, and each network device can include other numbers of terminal devices within its coverage range, which is not limited.

For example, the communication system shown in FIG. 1 can also include a mobility management entity (MME), an access and mobility management function (AMF), and other network entities, which are not limited in the embodiments of the present application.

For example, the communication system 100 shown in FIG. 1 can include network devices 110 and terminal devices 120 with communication functions, which can be the specific devices described above, and will not be described here again. The communication devices can also include other devices in the communication system 100, such as network controllers, mobility management entities, and other network entities, which are not limited in the embodiments of the present application.

[0045] For ease of understanding, some related technical knowledge related to the embodiments of the present application is introduced first. The following related technologies can be combined with the technical solutions of the embodiments of the present application in any way as an optional scheme, which all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0046] With the development of mobile communication technology, the application field of the Internet of Things is gradually expanding. However, without the support of external power supply, the 5G Internet of Things device is difficult to implement in practice. This is because the 5G device in the cellular network will consume tens of milliwatts of power even if it does not transmit or receive any data. This idle power consumption is due to the fact that the 5G device must be periodically measured and check for potential paging messages.

[0047] In order to reduce the power consumption of the terminal device, the NR system introduces a low-power wake-up module and an LP-WUS. The low-power wake-up module is also called a low-power wake-up receiver (LP-WUR) or a low-power wake-up radio (LP-WUR). The receiver can also be called a receiver. Exemplarily, when the terminal device is idle, the main communication module / receiver can be turned off or set to a deep sleep state, and only the LP-WUR is used to listen to the LP-WUS, so as to achieve the purpose of reducing the power consumption of the terminal device. The main communication module / receiver of the terminal device can also be called a main radio (MR), and correspondingly, the low-power wake-up module can also be simply called an LR. When the MR is woken up, the terminal device can enter a radio resource control (RRC) connected state. The LP-WUR of the terminal device can be continuously turned on to receive the LP-WUS. Therefore, the LP-WUR can be independent of the 5G device, that is, the 5G device can be in an off state when the LP-WUR is in an active state and searches for a potential LP-WUS. In order to ensure the low-power performance of the terminal device, it is necessary to embed the LP-WUS into the related communication system (for example, the NR system).

[0048] In some embodiments, the LP-WUS can support a bandwidth of 5MHz-20MHz. When the LP-WUS is embedded into the related communication system, the main communication module (or MR) and the low-power wake-up module (LP-WUR or LR) of the terminal device side can be two modules, or can be integrated together as one module. Among them, the LP-WUR can support multiple receiver architectures. The following will exemplarily illustrate the LP-WUR by taking three receiver architectures in FIGS. 2-4 as examples.

[0049] FIG. 2 is a schematic block diagram of an LP-WUR based on radio frequency (RF) envelope detection. The receiver architecture shown in FIG. 2 includes a matching network 201, an RF bandpass filter (BPF) 202, an RF low noise amplifier (LNA) 203, an RF envelope detector 204, a baseband (BB) asymmetric processing (AMP) 205, a BB low pass filter (LPF) 206, a 1-bit or multi-bit analog-to-digital converter (ADC) 207, and a digital BB processing 208.

[0050] In the architecture shown in FIG. 2, the RF signal is directly converted to a baseband signal by the RF envelope detector. Due to the absence of a local oscillator (LO) and a phase-locked loop (PLL), relatively low power consumption can be achieved. Optionally, the architecture can include a 1-bit or multi-bit ADC, an RF LNA, and / or a BB AMP, a high-Q matching network, and / or an RF BPF, and / or a BB LPF. Optionally, to support multiple frequency bands and / or carriers, multiple high-Q matching networks and / or RF BPFs or multiple off-chip components can be needed to suppress adjacent channel interference or interference from traditional NR signals and / or other LP-WUS on adjacent subcarriers and support frequency band and / or carrier tuning.

[0051] FIG. 3 shows a schematic block diagram of an LP-WUR based on a heterodyne architecture with intermediate frequency (IF) envelope detection. The receiver architecture shown in FIG. 3 includes a matching network 301, an RF BPF 302, an RF LNA 303, a mixer 304, an LO 305, an IF AMP 306, an IF BPF 307, an IF envelope detector 308, a BB AMP 309, a BB LPF 310, a 1-bit or multi-bit ADC 311, and a digital BB processing 312.

[0052] In the architecture shown in FIG. 3, the RF signal is frequency converted to an intermediate frequency (IF) signal by an RF mixer with an LO. The IF signal is converted to a baseband signal by an IF envelope detector. Depending on the design, there can be one or more intermediate frequency stages to achieve lower power consumption by relaxing the precision and stability requirements of the LO. The architecture can apply 1-bit or multi-bit ADCs. A high-Q matching network and / or an RF BPF and / or an IF BPF (and / or a BB LPF) can be used to suppress adjacent channel interference or interference from legacy NR signals and / or other LP-WUSs on adjacent subcarriers. Optionally, the architecture can apply some components to improve sensitivity, such as an RF LNA and / or an IF AMP and / or a BB AMP. Optionally, the architecture can achieve band and / or carrier tuning by tuning the LO frequency.

[0053] FIG. 4 shows a schematic block diagram of a LP-WUR based on a homodyne or zero-IF architecture with baseband (BB) envelope detection. The receiver architecture shown in FIG. 4 includes a matching network 401, an RF BPF 402, an RF LNA 403, a mixer 404, an LO 405, a BB AMP 406, a BB LPF / BPF 407, a 1-bit or multi-bit ADC 408, and a digital BB processing 409.

[0054] In the architecture shown in FIG. 4, band and / or carrier tuning can be achieved by tuning the LO frequency. Using a BB BPF / LPF instead of a high-Q matching network and / or an RF BPF, adjacent channel interference or interference from legacy NR signals and / or other LP-WUSs on adjacent subcarriers can be suppressed more efficiently and simply. An RF LNA can be applied to improve sensitivity. Baseband envelope detection (not shown in the figure) can be done in the analog domain (before ADC) or in the digital domain (after ADC).

[0055] For the design architecture of LP-WUR, LP-WUS can be deployed only in part of the frequency bands / carriers. For terminal devices, deploying LP-WUS in only some frequency bands / operators helps to reduce the cost of LP-WUR. Since the dynamic range of terminal devices is limited, supporting different frequency bands can require different RF modules (such as RF filters, LNAs, and oscillators in FIGS. 2-4), and limiting the frequency bands can reduce the cost. For the network side, deploying LP-WUS in only some frequency bands / carriers helps to reduce system overhead. Therefore, it is attractive to allow the number of frequency bands / carriers supported by LP-WUR to be smaller than the number of frequency bands / carriers supported by MR.

[0056] In some embodiments, for the idle / inactive mode terminal device, the cell reselection of the terminal device is not controlled by the network device (e.g., gNB), and therefore, the terminal device can freely select the frequency band / carrier to camp on.

[0057] The above introduces various LP-WUR architectures in combination with FIG. 2 to FIG. 4. All the LP-WUR architectures can be applicable to on-off keying (OOK) modulation. Some of the architectures can also be applicable to other modulations, such as frequency-shift keying (FSK).

[0058] OOK is a well-known modulation. OOK can allow low-power receivers to implement, i.e., envelope / energy detection. OOK is a special case of amplitude shift keying (ASK). OOK has only two amplitudes, ON and OFF. When applied to multi-carrier (MC) systems such as orthogonal frequency division multiple (OFDM), OOK is also called multi-carrier OOK because the ON and OFF signals usually span multiple subcarriers.

[0059] In some embodiments, in an OFDM-based MC-OOK system, a network node can perform multi-carrier amplitude shift keying (MC-ASK) waveform generation with encoded bits to generate a low-power wake-up signal (LP-WUS).

[0060] The above introduces various LP-WUR architectures and LP-WUS generation methods. When the network device sends the LP-WUS, how the LP-WUR in the terminal device receives the LP-WUS and how to perform paging detection are problems to be solved.

[0061] As an example, when the terminal device performs paging detection based on the LP-WUS mechanism, how to determine the paging occasion for paging detection is a problem to be considered. For example, whether the determination of the paging occasion needs to be associated with the reception occasion of the LP-WUS and how to associate the reception occasion of the LP-WUS need to be researched.

[0062] Based on this, the embodiment of the present application proposes a method for wireless communication. Through the method, the terminal device (e.g., UE) can determine the paging occasion for paging detection according to the reception occasion of the first wake-up signal and / or the load of the cell where the terminal device is located after receiving the first wake-up signal. As can be seen, the wireless communication method proposed in the embodiment of the present application uses a dynamically configured paging occasion in paging to improve the paging efficiency.

[0063] For ease of understanding, the method proposed in the embodiments of the present application is described in detail below in combination with FIG. 5. FIG. 5 is introduced from the perspective of interaction between the first terminal device and the network device.

[0064] The first terminal device is any kind of communication terminal that can receive the wake-up signal, which is not limited herein. In some embodiments, the first terminal device can be in an idle state or an inactive state. For example, the first terminal device can be a UE in an RRC idle (RRC_IDLE) / RRC inactive (RRC_INACTIVE) mode. In some embodiments, the first terminal device can be in a connected state (CONNECTED).

[0065] In some embodiments, the first terminal device is a communication terminal in an Internet of Things (IoT). The serving cell of the terminal device can be an NTN cell or a terrestrial network (TN) cell.

[0066] The first terminal device can include a first communication module and a second communication module. For example, the first terminal device can include two independent communication modules to save power consumption. The first communication module can be independent of the second communication module or independent of the first terminal device. For example, the first communication module and the second communication module in the first terminal device can be integrated together, but the running state and / or the off state of the two communication modules can be set separately.

[0067] As an example, the first communication module and the second communication module can be in different states respectively. For example, when the second communication module is in an off state, the first communication module can be in an active state of searching for a wake-up signal.

[0068] In some embodiments, the first communication module and the second communication module perform different functions respectively to reduce the power consumption of the first terminal device. The first communication module receives a first wake-up signal for waking up the second communication module, and the second communication module is used for paging detection.

[0069] As an example, the first communication module is a low-power / low-power signal receiving module, and the second communication module is a main communication module of the first terminal device. For example, the first communication module belongs to an LP-WUR, and the second communication module belongs to an MR. For another example, the first communication module is a low-power wake-up receiver (WUR), and the second communication module is an MR.

[0070] As an example, the first communication module can adopt any one of the receiver architectures described above, such as any one of FIGS. 2 to 4.

[0071] In some embodiments, the first terminal device can comprise the LP-WUR or similar functional module as described above to monitor the LP-WUS. The module to monitor the LP-WUS is the first communication module.

[0072] In some embodiments, the first terminal device can be one of any group or subgroup of terminal devices.

[0073] In some embodiments, the first terminal device can be one of any group or subgroup of terminal devices. As an example, the first terminal device can be any terminal device in a first subgroup of terminal devices. That is, when the first subgroup of terminal devices comprises a plurality of terminal devices, the first terminal device can be one of the plurality of terminal devices. As an example, the first terminal device can be any terminal device in a first group of terminal devices. The first group of terminal devices can be divided into a plurality of subgroups of terminal devices. The first subgroup of terminal devices in which the first terminal device is located can be configured or can vary dynamically.

[0074] As an example, the first group of terminal devices can be a portion or all of the terminal devices in a certain area that are in an idle state or an inactive state. The plurality of terminal devices in the first group of terminal devices can be divided into a plurality of subgroups based on different characteristics to determine a plurality of device subgroups, which are not limited herein.

[0075] By way of example, the plurality of subgroups of terminal devices can be determined based on the wake-up delay of the main communication module of the terminal device. By way of example, the plurality of subgroups of terminal devices can also be determined based on the type or priority of the traffic of the terminal device.

[0076] The network device can serve a cell in which the first terminal device is located. The network device can be any network device or core network device as described above, which is not limited herein. For example, the network device can be any base station as described above.

[0077] In some embodiments, the serving cell of the first terminal device is a cell or micro cell that can be served by the network device, which is not limited herein.

[0078] In some embodiments, the network device can be a communication device that supports LP-WUS functionality. By way of example, the network device can periodically transmit the LP-WUS to facilitate the wake-up of the terminal device. By way of example, the network device can implement the energy saving configuration of the association between the LP-WUS and the PO.

[0079] As an example, the cell served by the network device is an NTN cell. For example, the network device can be a satellite in the NTN that covers the area in which the terminal device is located, or can be a ground gateway or a ground network device in the NTN that communicates with the satellite.

[0080] In some embodiments, the terminal device and the network device can be relative. For example, the relay device can also be referred to as a terminal device relative to the network device. For example, the relay device can also be referred to as a network device relative to the terminal device.

[0081] In some embodiments, the network device can send a paging message to all terminal devices in the serving cell. When the network device is an access network device such as a base station, the network device can directly send the paging, or can receive the paging sent by the core network. When the network device is a core network device, the network device can send the paging to the access network device, so that the access network device sends the paging to the terminal device.

[0082] Referring to FIG. 5, in step S510, the first terminal device receives the first wake-up signal sent by the network device. The first wake-up signal can be the LP-WUS described above or a signal similar in function to the LP-WUS. For the sake of brevity, the LP-WUS is taken as an example in the following description.

[0083] In some embodiments, the first wake-up signal is one LP-WUS. One LP-WUS can be used to indicate whether one or more terminal devices are woken up. The terminal devices woken up by one LP-WUS belong to one terminal device group or one terminal device subgroup.

[0084] As an example, the first wake-up signal can be used for all terminal devices in the first terminal device subgroup.

[0085] The first terminal device can receive the first wake-up signal through the first communication module, so the first communication module is in an active state. In some embodiments, the first communication module can be used only for receiving the first wake-up signal, thereby reducing the power consumption of the first terminal device.

[0086] The first wake-up signal is the wake-up signal corresponding to the first terminal device, that is, the first wake-up signal can be used to indicate whether the first terminal device or part of the modules in the first terminal device is woken up. Whether the first terminal device or part of the modules in the first terminal device is woken up can mean that the communication module is switched from an off state to an active state, or can mean that the communication module is triggered to perform paging detection (or monitoring).

[0087] The first wake-up signal is used to wake up the second communication module in the first terminal device. It should be understood that, since the first communication module can be independent of the first terminal device, the second communication module being woken up can also be referred to as the first terminal device being woken up. Before receiving the first wake-up signal, the second communication module is in an off state. The first terminal device can determine whether to wake up the second communication module according to the first wake-up signal. In some embodiments, the first wake-up signal can also be used to wake up other modules in the first terminal device in addition to the second communication module.

[0088] In some embodiments, the first wake-up signal can be used to wake up the first terminal device to perform paging detection when the first wake-up signal indicates that the first terminal device needs to be woken up. For example, the first wake-up signal is used to wake up a main communication module to perform paging detection.

[0089] The first terminal device can receive the first wake-up signal at a first occasion. That is, the first occasion is a receiving occasion of the first wake-up signal. The network device can send the first wake-up signal at the first occasion or a time domain position corresponding to the first occasion. The time domain corresponding to the first occasion is mainly for a scenario with a long communication delay. The first occasion can be one of a plurality of occasions for receiving / detecting an LP-WUS.

[0090] Optionally, the first occasion can be one or more wake-up occasions (LP-WUS occasions, LOs) or one or more monitoring occasions (monitor occasions, MOs). The wake-up occasion can also be referred to as an LP-WUS occasion, and the monitoring occasion can also be referred to as an LP-WUS monitoring occasion.

[0091] Optionally, the first occasion can be an occasion for the first terminal device to detect an LP-WUS or one of a plurality of occasions for the first terminal device to detect an LP-WUS.

[0092] The first terminal device receives the first wake-up signal at the first occasion for paging detection. When the first occasion is a wake-up occasion / monitoring occasion, the first terminal device can perform paging detection at a paging occasion (PO) after the first occasion. Therefore, the periodicity of the wake-up occasion / monitoring occasion can be determined in combination with a discontinuous reception (DRX) mechanism associated with the PO.

[0093] In some embodiments, the paging occasion can be a listening opportunity of one set of physical downlink control channels (PDCCHs). The paging occasion can be composed of a plurality of slots.

[0094] As an example, one paging occasion can contain S synchronization signal block (SSB) beams. The paging message transmitted on each SSB beam can be the same or different. S can be indicated by a system information block (SIB). For example, S can be indicated or determined by ssb-PositionsInBurst in SIB1 message.

[0095] It should be understood that in the embodiments of the present application, the SSB can also represent a synchronization signal and physical broadcast channel block.

[0096] In some embodiments, when the period based on the wake-up occasion / monitoring occasion can be configured separately from the DRX period, multiple wake-up occasions / monitoring occasions can be mapped to a single paging occasion. In this scenario, it is possible to allow more frequent LP-WUS monitoring opportunities while maintaining the same DRX period. That is, the terminal device can receive the LP-WUS more frequently without shortening the DRX period.

[0097] In some embodiments, the first terminal device needs to wake up the second communication module after receiving the first wake-up signal to perform paging detection. Considering the wake-up time of the second communication module, the paging occasion of the first terminal device is not near a specific wake-up occasion / monitoring occasion (first occasion), but the wake-up occasion / monitoring occasion can be used to trigger the first terminal device to monitor the paging occasion.

[0098] As an example, the wake-up time of a terminal device can also be referred to as wake-up delay or wake-up duration. Different terminal devices can have different wake-up times, which are mainly related to hardware characteristics, power consumption optimization strategies, network conditions, and design goals of the terminal device itself, etc. For example, different terminal devices have different processor speeds, and the wake-up time will also be different: high-performance processors can enter active state faster than low-performance processors. For example, the speed of memory and storage also affects the wake-up time: high-speed memory can speed up the recovery from low-power state. For example, some terminal devices can adopt a more stringent battery management strategy to prolong battery life, which can result in a longer wake-up time. For example, different terminal devices can support different levels of low-power modes, and deeper low-power modes (such as longer sleep time) can require more time to wake up. For example, the base station (eNB or gNB) can configure different wake-up times and DRX cycles for different terminal devices according to network load and coverage. In areas with weak signals, terminal devices can need more time for signal synchronization and recovery, resulting in a longer wake-up time.

[0099] At step S520, the first terminal device determines a first paging occasion, i.e., a first PO, for paging detection according to the first information. Correspondingly, the network device can also determine the first paging occasion or the time domain position corresponding to the first paging occasion according to the same first information. That is, due to the transmission delay, there is a certain offset between the time domain position of the paging occasion at which the network device sends the paging and the time domain position of the paging occasion at which the terminal device side receives the paging.

[0100] The first terminal device performs paging detection in order to receive the paging message sent by the network device. It should be noted that the determination of the first paging occasion by the first terminal device can include determining the time domain position or index of the first paging occasion, or can include determining the time domain range of the first paging occasion.

[0101] In some embodiments, the first paging occasion can be a dynamically allocated paging occasion, so as to timely page the terminal device. As an example, when the period based on the wake-up occasion / monitoring occasion can be configured separately from the DRX period, the network device can consider dynamic paging occasion allocation. As an example, considering the wake-up time of the second communication module, the reception occasion of the first wake-up signal can trigger the first terminal device to monitor the dynamic paging occasion. As an example, the paging occasion corresponding to the first terminal device is dynamically changed.

[0102] It should be understood that in the embodiments of the present application, the serving cell where the first terminal device is located can also include a statically configured paging occasion. The statically configured paging occasion is, for example, a paging occasion determined by a calculation formula in a related protocol.

[0103] In some embodiments, the serving cell where the first terminal device is located can only provide dynamically allocated paging occasions. For example, in some small communication systems or local communication systems, the network device can only configure dynamic paging occasions in the serving cell, so that the terminal device can be paged at any time. In these systems, the terminal device can perform paging detection according to the dynamic paging occasions.

[0104] In some embodiments, the serving cell where the first terminal device is located can provide dynamically allocated paging occasions and statically configured paging occasions to meet the paging requirements of different types of terminal devices or different types of services. That is, in the serving cell, the network device can configure regular paging occasions and dynamic paging occasions. To achieve this configuration, the network device can also design wake-up occasions / monitoring occasions for triggering the terminal device to monitor the regular paging occasions and wake-up occasions / monitoring occasions for triggering the terminal device to monitor the dynamic paging occasions, respectively.

[0105] As an example, in the scenario where the serving cell provides regular paging occasions and dynamic paging occasions, in addition to configuring the first terminal device with regular paging occasions determined according to the terminal device identity (ID) (which can also be referred to as traditional paging occasions), the network device can also configure the first terminal device with dynamic paging occasions determined based on the reception occasions (e.g., monitoring occasions) of the wake-up signal.

[0106] In the scenario where the serving cell provides dynamic paging occasions, by utilizing the dynamic paging occasions, the first terminal device can effectively receive the first wake-up signal and monitor the first paging occasion, while minimizing unnecessary wake-up delay. In addition, by using dynamic paging occasions, any terminal device can be paged at substantially any time within a paging cycle.

[0107] As an example, when the RAN directly sends the paging message, once the first terminal device wakes up the MR (second communication module) to support the dynamic paging occasion, the RAN can send the paging message multiple times on multiple paging occasions within the paging cycle, so that the terminal device can receive the paging in time.

[0108] As an example, when the RAN sends the paging message to the terminal device according to the paging sent by the core network, the core network needs to send the paging information to the RAN multiple times through multiple paging occasions within the paging cycle to enable the dynamic paging occasion.

[0109] The first terminal device can determine the first paging occasion according to the first information. The first information can include the reception occasion of the first wake-up signal, and / or the load of the serving cell where the first terminal device is located. It should be understood that the first information can also include other paging-related information.

[0110] In some embodiments, when the first information comprises a reception occasion of the first wake-up signal, the first terminal device can determine the first paging occasion directly according to the reception occasion, or determine the first paging occasion in combination with other information. The other information is, for example, a configuration parameter of the paging occasion.

[0111] As an example, the first paging occasion can be determined according to the reception occasion of the first wake-up signal and a first paging time window (PTW). The first terminal device can determine the first PTW according to the configuration of the network device. As an implementation manner, the first PTW can be the nearest PTW corresponding to the first terminal device at the current time.

[0112] As an example, the first terminal device can determine the time domain range of the first paging occasion according to the positional relationship between the reception occasion of the first wake-up signal and the first PTW. The first terminal device can perform paging detection in the time domain range.

[0113] As an implementation manner, when the reception occasion of the first wake-up signal is before the first PTW, the first paging occasion is within the first PTW. For example, after the first terminal device receives the wake-up signal before the first PTW, the first terminal device can monitor the paging occasion within the first PTW. As another example, the first wake-up signal can be monitored outside the PTW. After receiving the LP-WUS, the terminal device can monitor the paging occasion in the next PTW. That is, the terminal device can detect the paging occasion in the next PTW period to ensure the timeliness of the terminal device service.

[0114] As an implementation manner, when the reception occasion of the first wake-up signal is within the first PTW, the first paging occasion is within the first PTW or a second PTW, and the second PTW is the next time window adjacent to the first PTW. For example, the first wake-up signal can be monitored within the first PTW. After the first terminal device receives the first wake-up signal within the first PTW, the first terminal device can determine the time domain range of the first paging occasion according to the wake-up time or the conversion time of the first terminal device.

[0115] In some scenarios, even if the first wake-up signal can be transmitted and received immediately after the paging arrives (within the first PTW), the first terminal device can need to wait for the next PTW (the second PTW) to detect the PO because the conversion time is long. In other words, because the remaining time of the first PTW is less than the conversion time, the first paging occasion is within the second PTW.

[0116] In some scenarios, the first wake-up signal and the first paging occasion can be located in the same PTW. For example, after the first terminal device receives the first wake-up signal in the first PTW, if the remaining time in the first PTW is greater than the switching time, the first paging occasion can be detected in the first PTW.

[0117] As an implementation manner, the first terminal device can detect the first wake-up signal before and in the first PTW, so as to wake up the second communication module in time for paging detection.

[0118] In some embodiments, the first information can be used to determine a first paging frame (PF) in which the first paging occasion is located. As an example, after the first paging frame is determined, the first terminal device can further determine the first paging occasion. As an example, after the first paging frame is determined, the first terminal device can monitor the first paging occasion in the first paging frame.

[0119] As an example, the first paging frame can belong to a first type of paging frame. The first type of paging frame can be a dynamic paging frame. That is, the first type of paging frame does not belong to a paging frame configured in advance by the network device, but is determined according to parameters such as paging arrival time, transmission / reception time of the wake-up signal, and wake-up time of the terminal device.

[0120] As an example, when the first information includes the reception occasion of the first wake-up signal, the first paging frame can be determined according to the system frame corresponding to the reception occasion of the first wake-up signal. For example, the first terminal device can determine the paging frame based on the frame in which the first wake-up signal is received, thereby realizing the use of a dynamic paging occasion.

[0121] As an example, the first paging occasion can belong to a first type of paging occasion. The first type of paging occasion can be a dynamic paging occasion. The static paging occasion corresponding to the first paging occasion can belong to a second type of paging occasion.

[0122] As an example, when the first information includes the reception occasion of the first wake-up signal, the first paging occasion can be determined according to the time slot corresponding to the reception occasion of the first wake-up signal. That is, the reception occasion of the first wake-up signal can be directly used to determine the first paging occasion.

[0123] As an embodiment, the first paging frame can belong to a second type of paging frame. The second type of paging frame can include a number of paging occasions which can dynamically change. Illustratively, when the first information includes a load condition of a serving cell where the first terminal device is located, the number of paging occasions included in the second type of paging frame can dynamically change according to the load condition. For example, the number of paging occasions included in the second type of paging frame is determined according to the load of the serving cell in a first time period. The index of the first paging occasion is determined according to the number of paging occasions included in the first paging frame.

[0124] As an example, the first time period can be determined according to a higher layer instruction. As an example, the first time period can be one or more frames, one or more subframes, or one or more time slots.

[0125] Optionally, the dynamic paging frames belonging to the first type of paging frame and the second type of paging frame can be determined according to the calculation formula of the existing paging frame in the case of introducing a dynamic offset. For example, when calculating the system frame number (SFN) of the dynamic paging frame, a dynamic PO offset (DPO ID ) can be introduced based on the terminal device ID (UE offset ). Wherein, the DPO offset can be determined by the lower limit of the system frame number SFN LO determined based on the first occasion and the offset of the MR ramp-up (RU offset ). Optionally, the lower limit of the SFN LO may be expressed as (SFN-SFN LO -RU offset )×(N div T); wherein N is the number of paging frames in a paging period T.

[0126] As an embodiment, the first paging frame can also belong to a third type of paging frame. The third type of paging frame is determined according to the static configuration of the serving cell. Although the third type of paging frame can be a statically configured paging frame, the paging occasions in this paging frame can be dynamically configured. For example, the position of the paging occasion in the third type of paging frame is dynamically changed. As another example, when the first paging frame belongs to the third type of paging frame, the actual number of paging occasions in the first paging frame can also be determined according to an adjustment factor δ. That is, the number of paging occasions configured in advance for the first paging frame by the network device does not change, but in the actual process, the network device can dynamically adjust the actual number of paging occasions in the first paging frame according to the load of the cell.

[0127] From the above embodiments, it can be seen that the paging frame type to which the first paging frame in the embodiments of the present application belongs can be any one of a first type of paging frame, a second type of paging frame, and a third type of paging frame. The first terminal device can determine the type of the first paging frame according to the first information, and then determine the first paging occasion according to a specific manner corresponding to the type of the paging frame. The following will be specifically described in combination with three embodiments.

[0128] In some embodiments, when the first information includes the load of the serving cell where the first terminal device is located, the current load of the serving cell can be used to determine the index of the first paging occasion. The load of the serving cell is related to one or more of the following information: the maximum number of paging requests of the serving cell; the current number of paging requests of the serving cell; the service type of the serving cell.

[0129] As an example, the maximum number of paging requests of the serving cell can include the maximum number of paging requests that the serving cell can handle. The maximum number of paging requests can include paging requests from the core network, or can include paging requests from the RAN itself.

[0130] As an example, the current number of paging requests of the serving cell can refer to the number of paging requests of the serving cell in the current paging cycle. The number of paging requests can include paging requests from the core network, or can include paging requests from the RAN itself.

[0131] As an example, the service type of the serving cell can be one of the references for the load of the serving cell. For example, when the number of high-priority service types in the serving cell increases, the load of the serving cell increases.

[0132] As an example, the load of the serving cell can be divided into two states of high load and low load, to calculate the number of paging occasions in a paging frame under different loads. It is assumed that there are Ns paging occasions (Ns≥1) in each initial paging frame, the number of paging occasions in the paging frame can be increased in the high load case, and the number of paging occasions in the paging frame can be reduced in the low load case. Increasing the number of paging occasions in the paging frame in the high load case can disperse the paging requests. Reducing the number of paging occasions in the paging frame in the low load case can reduce unnecessary power consumption. As known from the foregoing, the paging frame whose number of contained paging occasions can be dynamically adjusted is the second type of paging frame.

[0133] By way of example, the load of the serving cell can be determined according to a network load coefficient L. For example, L>50% is set as a high load scenario, and L≤50% is set as a low load scenario. When the initial number of paging occasions of the paging frame is Ns, the number of paging occasions Ns' in the high load case high and the number of paging occasions Ns' in the low load case low may be represented as follows, respectively:

[0134]

[0135]

[0136] As an implementation, the network load coefficient L can be related to the number of paging requests. L can be the quotient between the current number of paging requests of the serving cell and the maximum number of paging requests, i.e., L = current number of paging requests / maximum number of paging requests.

[0137] As another implementation, L can be other values representing the load of the cell. The values are set according to the specific situation of the network device coverage.

[0138] Optionally, the adjustment factor δ described above has a certain correspondence with the load coefficient L. The difference is that δ can be less than 1, greater than 1, or equal to 1; L can only be less than or equal to 1.

[0139] In the above embodiments, the network device can dynamically adjust the number of paging occasions in each paging frame. This dynamic adjustment mechanism ensures that the network can effectively handle more paging requests in high-load situations, while optimizing the power consumption of the terminal device in low-load situations.

[0140] In some embodiments, the first information can further include the wake-up time of the first terminal device or the transition time of the second communication module. That is, when the first terminal device receives the first wake-up signal and determines the first paging occasion, the first terminal device also needs to consider the transition time from monitoring the wake-up signal to monitoring the paging message. The transition time can also be the time of waking up the second communication module for paging detection.

[0141] Optionally, the transition time of the second communication module can include the transition time (transition time) including the first wake-up signal processing, the ramp-up of the second communication module from the ultra-deep sleep state, and the cell reselection / synchronization.

[0142] As an example, the first paging occasion can be determined according to the reception time of the first wake-up signal and the transition time of the second communication module.

[0143] As an example, the first information includes the transition time of the second communication module, and the first paging occasion can be one of the multiple paging occasions. The multiple paging occasions can be located after the first time domain position. The first time domain position is determined according to the reception time of the first wake-up signal and the transition time.

[0144] In the above example, the multiple paging occasions can be one or more existing paging occasions defined for the network device, but the existing paging occasions are located after the switching time of the second communication module. It should be noted that the switching time of the second communication module can also be referred to as the switching time of the first terminal device. The switching time can refer to the time at which the first terminal device starts to perform paging detection.

[0145] In the above example, the first time domain position T1 of the first paging occasion is the sum of the reception occasion T0 of the first wake-up signal and the switching time t, i.e., T1 = T0 + t.

[0146] To facilitate understanding, the influence of the switching time of the second communication module on the first paging occasion is schematically explained below in combination with FIG. 6. FIG. 6 mainly introduces the processing flow of a network device 610 and a terminal device 620. The first communication module included in the terminal device 620 is a WUR, and the second communication module is an MR. The wake-up signal used to wake up the terminal device 600 is an LP-WUS. The dynamic paging occasions configured by the network device 610 for the terminal device 620 include an additional paging occasion (additional PO) and a legacy paging occasion (legacy PO).

[0147] Referring to FIG. 6, in step S61, the network device 610 receives a paging from a core network, i.e., paging arrived.

[0148] In step S62, the network device 610 waits for a monitoring occasion of a wake-up signal to send an LP-WUS (waiting for LP-WUS MO).

[0149] In step S63, the WUR of the terminal device 620 performs a wake-up signal processing flow after receiving the LP-WUS. After step S63 is performed, a wake-up process and a synchronization process of the MR are triggered.

[0150] In step S64, the MR of the terminal device 620 performs a ramp-up of the wake-up process.

[0151] In step S65, the MR of the terminal device 620 performs a synchronization (sync) or re-synchronization (re-sync) process.

[0152] In step S66, the network device 610 transmits a paging message in a paging occasion after the MR completes synchronization (step S65).

[0153] As can be seen from FIG. 6, for the network device 610, the time between the paging arrival in S61 and the sending of the paging in the paging occasion is the paging latency. For the terminal device 620, the switching time includes the three processes in S63-S65. When the MR is ready for paging monitoring after synchronization / resynchronization, the terminal device 620 can immediately monitor the dynamic paging occasion, and the network device 610 can send the paging in the dynamic paging occasion to reduce the latency.

[0154] The above describes various determination methods of the dynamic paging occasion (the first paging occasion) in combination with FIG. 5 and FIG. 6. In these methods, the paging frame in which the first paging occasion is located can belong to any of the three types of paging frames. The following describes the method of determining the first paging occasion through the three types of paging frames in combination with three embodiments.

[0155] The first paging frame in the embodiment 1 belongs to the first type of paging frame. The system frame number of the first paging frame can be determined according to the frame number of the system frame corresponding to the first wake-up signal receiving occasion. The system frame number of the first paging frame can also be determined according to the frame number corresponding to the switching time of the second communication module (or the first terminal device).

[0156] As an example, the frame number of the first paging frame can be the sum of the frame number of the system frame in which the first terminal device receives the first wake-up signal and the frame number corresponding to the switching time of the second communication module.

[0157] The first paging frame in the embodiment 2 belongs to the second type of paging frame. The number of paging occasions in the second type of paging frame dynamically changes. In this embodiment, the second type of paging frame can also be determined according to the manner of the regular paging frame, except that the number of paging occasions in the paging frame changes with the load change of the serving cell. The number of paging opportunities dynamically adjusted according to the load coefficient L is Ns'.

[0158] As an example, the system frame number SFN of the first paging frame satisfies the formula (SFN+PF offset )mod T=(T div N)×(UE ID mod N);wherein, T is the paging cycle, T=min (default paging cycle, UE specific DRX cycle); N is the number of paging frames contained in T, a paging frame is composed of multiple paging occasions; PF offset is the frame offset of PF; UE ID is the ID of the first terminal device.

[0159] As an example, the number of paging occasions in the first paging frame is Ns' described above. When the load of the current serving cell is high, Ns'=Ns' high ; when the load of the current serving cell is low, Ns'=Ns'.low .

[0160] As an example, the index i of the first paging timing s For: i s =floor(UE) ID / N)modNs′;

[0161] Among them, UE ID The identifier is the first terminal device, N represents the number of paging frames in one cycle, and Ns′ represents the number of paging opportunities included in the first paging frame.

[0162] The first paging frame in Example 3 belongs to the third type of paging frame. The third type of paging frame is a paging frame statically configured by the network device. Therefore, the system frame number of the first paging frame can be determined according to the method in Example 2.

[0163] As an example, the actual number of paging opportunities in a third-type paging frame is related to the adjustment factor δ. For instance, when the initial number of paging opportunities is Ns, a single paging frame in the third-type paging frame can contain δ×Ns paging opportunities. Here, the adjustment factor δ is a rational number that can vary depending on changes in the current cell load or the type of service.

[0164] As an example, the index i of the first paging timing s This can be represented as: i s =floor(UE) ID / N)mod(δ×Ns);

[0165] Among them, UE ID The identifier is the first terminal device, N represents the number of paging frames in one period, Ns represents the number of paging opportunities in the third type of paging frame, and δ represents the adjustment factor related to the load of the serving cell.

[0166] The method embodiments of this application have been described in detail above with reference to Figures 1 to 6. The apparatus embodiments of this application will now be described in detail with reference to Figures 7 to 9. It should be understood that the descriptions of the apparatus embodiments correspond to the descriptions of the method embodiments; therefore, any parts not described in detail can be referred to the preceding method embodiments.

[0167] Figure 7 is a schematic block diagram of a device for wireless communication according to an embodiment of this application. The device 700 can be any of the first terminal devices described above. The device 700 shown in Figure 7 includes a first communication module 710 and a second communication module 720.

[0168] The first communication module 710 can be used to receive a first wake-up signal, which is used to wake up the second communication module.

[0169] The second communication module 720 can be configured to determine a first paging occasion for paging detection according to the first information; wherein the first wake-up signal is received by the first communication module, the paging detection is performed by the second communication module, and the first information comprises a receiving occasion of the first wake-up signal and / or a load of a serving cell where the first terminal device is located.

[0172] Optionally, the first paging occasion is in a first paging frame belonging to a first type of paging frame, and a time domain position of the first type of paging frame is related to a receiving occasion of the terminal device for the wake-up signal.

[0174] Optionally, the first information comprises the load of the serving cell where the first terminal device is located, and the load is related to one or more of the following information: a maximum number of paging requests of the serving cell; a current number of paging requests of the serving cell; and a service type of the serving cell.
