Description

Technical Field

[0001] The embodiments of this disclosure primarily relate to the field of communications, and more specifically to a communication method, communication device, communication apparatus, chip, computer-readable storage medium, and computer program product. Background Technology

[0002] A communication system can be viewed as a facility that enables a communication session between two or more entities (such as communication devices, base stations, and / or other nodes) by providing carrier waves between various entities involved in the communication path. A communication system can be a wireless communication system. Wireless communication systems can be systems based on various wireless communication standards, such as those provided by the 3rd Generation Partnership Project (3GPP). With the development of wireless technology, the sixth generation (6G) and related wireless access technology standards have attracted widespread interest. Currently, extensive research and discussion are underway regarding improvements to energy-saving features related to terminal devices in fifth-generation (5G) wireless communication technology. Summary of the Invention

[0003] Embodiments of this disclosure provide a communication method, communication device, communication apparatus, chip, computer-readable storage medium, and computer program product for paging. According to embodiments of this disclosure, a unified downlink wake-up signal mechanism enables terminal devices to achieve more accurate paging message monitoring with low power consumption, thereby saving terminal device energy consumption and improving overall network energy efficiency while meeting certain paging performance requirements.

[0004] In a first aspect of this disclosure, a communication method is provided. This method can be applied to a terminal device. In this disclosure, a terminal device can refer to a terminal equipment, a component within the terminal equipment (e.g., a processor, chip, module, communication module, circuit or chip responsible for communication functions), or a logic module or software capable of implementing all or part of the terminal equipment's functions. The following description uses a terminal equipment as an example. The method includes: receiving first indication information and first information, wherein the first indication information is used to indicate an indication method associated with the first information, and the first information is used to indicate whether the terminal equipment monitors first control information related to paging; and determining whether to monitor first downlink control information based on the first indication information and the first information. In this way, embodiments of this disclosure adapt to different paging scenarios through flexible indication methods, saving terminal equipment power consumption and improving network resource utilization efficiency.

[0005] In some implementations of the first aspect of this disclosure, the method further includes: based on determining that first control information is being monitored, monitoring the first control information at a paging timing associated with the first information, wherein the first control information includes second indication information used to indicate a paging message. In other implementations, based on determining that the first control information is not being monitored, the first control information is not monitored. In this way, embodiments of this disclosure enable the terminal device to wake up the main receiver or exit a low-power operating mode when paging is required, thereby improving system energy efficiency.

[0006] In some implementations of the first aspect of this disclosure, the first information includes multiple bits, and the first indication information is configured to indicate one of multiple methods, including a first method and a second method. The first method is configured such that the multiple bits of the first information are divided into multiple bit sequences, which are used to determine whether to monitor the first control information. The second method is configured such that a single bit from the multiple bits of the first information is used to determine whether to monitor the first control information. In this way, embodiments of this disclosure support two efficient subgroup indication methods through a single message structure. The network can dynamically select the more efficient mode based on the current number of paging subgroups, thereby achieving higher information carrying efficiency and reducing signaling overhead under various load scenarios.

[0007] In some implementations of the first aspect of this disclosure, in a first embodiment, a bit sequence is configured to indicate the identifier of a terminal device subgroup, the terminal device subgroup including terminal devices. The method further includes: determining whether to monitor first control information based on the value of the bit sequence and the identifier of the terminal device subgroup to which the terminal device belongs. In this manner, embodiments of this disclosure can use bit sequences to identify terminal device subgroups, applicable to scenarios involving paging multiple subgroups, and improving the flexibility of signaling indication.

[0008] In some implementations of the first aspect of this disclosure, the bit sequence comprises N bits, and the maximum value of the bit sequence is 2. N The number of terminal device subgroups is less than or equal to 2 N N is a positive integer.

[0010] In some implementations of the first aspect of this disclosure, in a second embodiment, a single bit is configured to indicate a single terminal device subgroup, the single terminal device subgroup including terminal devices. The method further includes: determining whether to monitor first control information based on the position of the single bit among multiple bits, the value of the single bit, and the identifier of the terminal device subgroup to which the terminal device belongs. In this manner, embodiments of this disclosure can use a bitmap to identify terminal device subgroups, which is suitable for scenarios involving paging multiple terminal device subgroups.

[0011] In some implementations of the first aspect of this disclosure, the position of a single bit among multiple bits corresponds to the identifier of the terminal device subgroup to which the terminal device belongs.

In some implementations of the first aspect of this disclosure, the value of a single bit is 1 or 0, where 1 indicates monitoring the first control information and 0 indicates not monitoring the first control information. In this way, embodiments of this disclosure propose a monitoring result judgment rule, making the signal analysis rule simple and unified.

[0073] This disclosure addresses the functional redundancy and inability to organically combine two paging wake-up mechanisms in idle or inactive terminal devices in 5G communication systems, which restricts system energy efficiency. It proposes a communication method based on downlink wake-up signal (DL-WUS), combining the paging early indication (PEI) mechanism and the low power-wake-up signal (LP-WUS) mechanism, and introducing a dynamic indication method to fully leverage the advantages of both mechanisms, simplify the process, and improve the paging efficiency and energy efficiency of the communication system.

[0074] The principles and implementation of this solution will be described in detail below with reference to the accompanying drawings.

[0075] Figure 1 A schematic diagram of an example communication system 100 that may be implemented according to embodiments of this disclosure is shown. Figure 1As shown, the communication system 100 may include at least one terminal device ( Figure 1 The diagram shows terminal devices 110-1 and 110-2 (hereinafter referred to as terminal device 110 for convenience) and at least one network device ( Figure 1 The image shows network device 120 and satellite 130. Network device 120 and satellite 130 in this document are radio access network (RAN) devices. Network device 120 and satellite 130 can provide one or more cells ( Figure 1 Cell 121 is shown in the diagram, serving one or more terminal devices. Satellite 130 can employ a transparent forwarding mode, acquiring downlink data from access network device 120 and forwarding it to terminal device 110, as well as forwarding uplink data received from terminal device 110 to access network device 120, performing only filtering, frequency conversion, RF amplification, and RF transceiver on-board. Satellite 130 can also employ a regenerative forwarding mode, possessing all or part of the functions of a gNB, performing functions such as modulation, demodulation, and channel coding / decoding. When using regenerative forwarding mode, satellite 130 itself becomes a network device, such as an access network device.

[0076] Terminal device 110 can connect wirelessly to network device 120 and satellite 130. Terminal devices 110-1 and 110-2 can connect wirelessly. Network device 120 and satellite 130 can connect wirelessly.

[0077] like Figure 1 As shown, the communication system 100 may further include a core network (CN) 140. Terminal device 110 can communicate with one or more CN devices (not shown) in CN 140 via network device 120 and satellite 130. Network device 120 and satellite 130 can be connected to CN 140 wirelessly or via wired means. Network device 120 can be implemented as a physical device independent of CN devices, or it can be implemented as a physical device integrating some of the functions of CN devices.

[0078] In the following text, for the sake of brevity, network device 120 can be used in a broad sense, which may include satellite 130. In this case, satellite 130 adopts regenerative forwarding mode and has all or part of the functions of gNB.

[0079] It should be understood that Figure 1 The number and type of terminal devices or network devices described are merely examples and do not imply any limitation on this disclosure. Communication system 100 may involve any suitable number of terminal devices and / or network devices and / or cells suitable for implementing embodiments of this disclosure.

[0080] The communication in communication system 100 can conform to any suitable communication standard, including but not limited to wideband code division multiple access (WCDMA), code division multiple access (CDMA), long-term evolution (LTE), LTE evolution, LTE-Advanced (LTE-A), machine-type communication (MTC), etc. Furthermore, communication between terminal equipment and network equipment can be performed according to any suitable generation communication protocol, including but not limited to fourth-generation (4G), fifth-generation (5G), sixth-generation (6G) communication protocols, future wireless communication protocols, or other existing or future suitable communication protocols.

[0081] It should be noted that the embodiments of this disclosure can be applied to various suitable communication systems. Considering the rapid development of communication technologies, there will naturally be future types of communication technologies and systems, which this disclosure may be combined with. Communication system 100 is merely an example and does not imply that the scope of this disclosure is limited to a specific system.

[0082] Continue to refer to Figure 1 Terminal device 110 and network device 120 can communicate via a wireless communication channel. The channel from terminal device 110 to network device 120 can be referred to as the uplink channel. The channel from network device 120 to terminal device 110 can be referred to as the downlink channel.

[0083] In the currently agreed-upon protocol, there are two methods for optimizing the paging process to reduce power consumption on the UE side: the paging early indication (PEI) method and the low-power-wake-up signal (LP-WUS) method.

[0084] The purpose of PEI (Pre-Paging Indicator) is to notify the UE in advance of an upcoming paging event, allowing the UE to prepare before actually receiving the paging message. This optimizes the paging process, reduces power consumption of UEs in idle or inactive states, and improves network efficiency. After the network configures PEI for the UE, the UE can monitor PEI during discontinuous reception (DRX) cycles. PEI can instruct the UE's subgroup to monitor the associated paging occasion (PO). If the UE does not detect PEI or the PEI does not indicate relevant information, the UE enters sleep mode during that DRX cycle, monitors PEI before the start of the next DRX cycle, and repeats the above process.

[0085] Before monitoring the PO, idle or inactive UEs need to detect the synchronization signal block (SSB) 2-3 times to achieve accurate synchronization. If the PEI indicates that the UEs in the subgroup do not need to monitor the PO, then the UEs in the subgroup do not need to perform SSB detection or detect subsequent paging messages, thereby achieving the purpose of energy saving.

[0086] Another energy-saving benefit of PEI comes from the introduction of subgroups. Currently, the paging mechanism involves multiple UEs sharing the same PO. If a UE is not configured with PEI, all UEs associated with that PO will monitor paging-related downlink control information (DCI) on that PO. This can lead to more false paging, meaning the network does not page the UE, but the UE still needs to detect paging DCI on that PO. The subgroup mechanism can divide UEs configured on a single PO into several subgroups to reduce failed paging, thereby achieving energy savings.

[0087] The LP-WUS mechanism was introduced in 5G release (Rel-) 18. The UE uses a separate low-power wake-up receiver module to receive low-power wake-up signals, which determine whether to wake up the main radio (MR) for data reception. When the UE does not detect a wake-up signal, the MR remains powered off or in deep sleep to conserve power. Its energy efficiency gain primarily stems from the UE using the low-power receiver for signal reception for extended periods, only waking up the MR receiver when needed. This is because the low-power receiver has a simpler circuitry compared to the MR receiver, resulting in a very low baseline power consumption (static power consumption) during operation.

[0088] In 5G NR, LP-WUS is mainly divided into two types: on-offset keying (OOK) symbols and symbols superimposed on OOKON symbols based on orthogonal frequency division multiplexing (OFDM) sequences. The advantage of using OOK symbols is that the wake-up receiver structure can be very simple, requiring only envelope detection to receive the wake-up signal, resulting in very low power consumption. However, the disadvantage is lower coverage, less than the NR common reference signal. To achieve the same coverage as the NR common reference signal, more resources are needed, leading to lower resource utilization.

[0089] For idle or inactive UEs, the LP-WUS can carry up to 5 bits of information to wake up UEs in a specific subgroup or all subgroups for paging monitoring. The UE uses a low-power receiver to detect the LP-WUS and decode its information. If the UE finds that the LP-WUS indicates that its subgroup is monitoring the PO, it wakes up the master receiver to monitor the PO. If the UE does not detect the LP-WUS, or if the information in it does not indicate that its subgroup is monitoring the PO, the master receiver remains in sleep or powered off state during the current DRX cycle.

[0090] In summary, UEs supporting the LP-WUS mechanism consistently use a low-power receiver to monitor LP-WUS, only waking up the main receiver when the network indicates it is monitoring the PO (Positioning Point). This approach improves energy efficiency. Compared to PEI (Power over Internet Protocol), this method not only reduces SSB (Service Subsystem for Buses) and paging message detection, but also offers the advantage of using only a low-power receiver module to decode the wake-up signal, resulting in higher energy efficiency. Furthermore, the detection complexity of both OOK symbols and OFDM-based symbols superimposed on OOK ON symbols is lower than that of DCI-based PEI signals, which is another reason why LP-WUS is more energy-efficient than PEI.

[0091] At the RAN1 122b meeting, it was generally agreed by those skilled in the art that OFDM-based signals would be used as downlink WUS in next-generation communication systems, allowing for greater payload capacity while maintaining coverage. The following agreements were reached at the RAN1#122b meeting: Research and evaluate OFDM sequence-based downlink (DL) WUS and corresponding mechanisms for improving energy efficiency (EE) in 6G radio (6GR), at least in the following aspects: For DL-WUS coverage targets, such as the same as the physical downlink control channel (PDCCH), common synchronization signal, or other signals; Measurement and / or synchronization System overhead, and network power consumption, or UE power saving for UEs operating with DL-WUS; RRC status; Other features.

[0092] Therefore, while the PEI mechanism for idle / inactive states achieves energy savings, its energy-saving gain is less than that of LP-WUS. Furthermore, PEI is in DCI format, requiring the main receiver to be activated for monitoring and detection, resulting in higher energy consumption. In contrast, LP-WUS uses OOK or OFDM-based signals, which have lower detection complexity and can be monitored using low-power receivers or low-power / energy-efficiency modes.

[0093] Currently, 5G NR supports both LP-WUS and PEI. A UE can support either LP-WUS or PEI, or both, or neither. This depends on the UE's capabilities and whether the network has configured the relevant parameters. However, both methods still have the following issues: 1) The two mechanisms overlap to some extent, which limits the improvement of UE energy efficiency. Therefore, it is necessary to design a communication method for DL-WUS to integrate the two and improve energy saving.

[0094] 2) In terms of paging efficiency, both methods have their advantages and disadvantages. When the number of UEs or subgroups being paged simultaneously is large, the PEI-based information carrying method is more efficient, while the LP-WUS method is more efficient. Therefore, it is necessary to design a communication method for DL-WUS to realize energy-efficient UE paging wake-up mode indication and improve energy saving gains.

[0095] To at least partially solve the above problems and improve system performance, this invention proposes a DL-WUS transmission method for idle / inactive UEs, which improves energy efficiency while realizing the relevant functions.

[0096] Figure 2A A schematic signaling interaction diagram of a communication process according to some embodiments of the present disclosure is shown. For convenience, reference will be made to... Figure 1The following example illustrates the communication process 200A. The communication process 200A may involve terminal device 110 and network device 120. It should be understood that the communication process 200A can be executed between terminal device 110 and network device 120, between a communication device supporting the functionality of terminal device 110 and network device 120, between terminal device 110 and a communication device supporting the functionality of network device 120, or between a communication device supporting the functionality of terminal device 110 and a communication device supporting the functionality of network device 120. For example, the communication device supporting the functionality of terminal device 110 and the communication device supporting the functionality of network device 120 may be a chip such as a SoC, a modem, or a module in a communication device; this disclosure does not limit this.

[0097] like Figure 2A As shown, at position 205, terminal device 110 can receive first indication information and first information from network device 120. The first indication information can be used to indicate an indication method associated with the first information, and the first information can be used to indicate whether the terminal device monitors first control information related to paging. At position 210, terminal device 110 can determine whether to monitor first downlink control information based on the first indication information and the first information. In this way, embodiments of this disclosure adapt to different paging scenarios through flexible indication methods, saving terminal device power consumption and improving network resource utilization efficiency.

[0098] In some example embodiments, the terminal device 110 may also monitor the first control information at a paging timing associated with the first information, based on a determination that the first control information is being monitored. The first control information may include second indication information, which can be used to indicate a paging message. In other implementations, the first control information is not monitored based on a determination that the first control information is not being monitored. In this way, embodiments of the present disclosure can wake up the main receiver or exit a low-power operating mode when a paging message needs to be received, thereby improving system energy efficiency.

[0099] In some example embodiments, the first information may include multiple bits, and the first indication information may be configured to indicate one of multiple methods. These multiple methods may include a first method and a second method. The first method may be configured such that the multiple bits of the first information are divided into multiple bit sequences, which are used to determine whether to monitor the first control information. The second method may be configured such that a single bit from the multiple bits of the first information is used to determine whether to monitor the first control information. In this way, embodiments of this disclosure support two efficient subgroup indication methods through a single message structure. The network can dynamically select the more efficient mode based on the current number of paging subgroups, thereby achieving higher information carrying efficiency and reducing signaling overhead under various load scenarios.

[0100] In some example embodiments, in a first approach, the bit sequence can be configured to indicate the identifier of a terminal device subgroup, which includes terminal devices. Terminal device 110 can also determine whether to monitor first control information based on the value of the bit sequence and the identifier of the terminal device subgroup to which it belongs. In this manner, embodiments of this disclosure can use bit sequences to identify terminal device subgroups, applicable to scenarios involving paging multiple discrete subgroups.

[0101] In some example embodiments, the bit sequence may include N bits, and the maximum value of the bit sequence is 2. N The number of terminal device subgroups is less than or equal to 2 N In this way, embodiments of this disclosure achieve a match between the indication method design and the network configuration subgroup size through bit sequences.

[0102] In some example embodiments, terminal device 110 may also determine whether to monitor the first control information based on the correspondence between the value of the bit sequence and the identifier of the terminal device subgroup to which the terminal device belongs. In other implementations, it is determined not to monitor the first control information based on the fact that the value of the bit sequence does not correspond to the identifier of the terminal device subgroup to which the terminal device belongs.

[0103] In some example embodiments, in the second approach, a single bit can be configured to indicate a single terminal device subgroup, which includes terminal devices. Terminal device 110 can also determine whether to monitor the first control information based on the position of the single bit among multiple bits, the value of the single bit, and the identifier of the terminal device subgroup to which the terminal device belongs. In this manner, embodiments of the present disclosure can use a bitmap to identify terminal device subgroups, which is suitable for scenarios involving paging multiple terminal device subgroups.

[0104] In some example embodiments, the position of a single bit among multiple bits can correspond to the identifier of the terminal device subgroup to which the terminal device belongs. The terminal device 110 can also determine whether to monitor the first control information based on the value of a single bit. In this way, the embodiments of this disclosure simplify the judgment logic of the terminal device and reduce the processing power consumption and latency of the wake-up signal.

[0105] In some example embodiments, the value of a single bit can be 1 or 0. 1 can indicate monitoring of the first control information, and 0 can indicate not monitoring the first control information. In this way, embodiments of this disclosure propose a monitoring result judgment rule, making the signal analysis rule simple and unified.

[0106] In some example embodiments, the identifier of the terminal device subgroup to which terminal device 110 belongs can be determined based on one or more of the following: terminal device identifier, number of paging frames in a paging cycle, number of paging opportunities in a paging frame, and number of subgroups in a paging opportunity. In this way, embodiments of this disclosure provide a standardized method for determining subgroup identifiers, achieving consistency in subgroup division between network devices and terminal devices, and this method is compatible with existing paging parameters, facilitating system integration and deployment.

[0107] In some example embodiments, the terminal device 110 may also monitor first information at a first time unit, the first time unit being determined based on first configuration information. In this way, embodiments of the present disclosure enable the terminal device to know the temporal location of the wake-up signal, thereby allowing detection within a necessary time window, reducing active time, and achieving energy savings.

[0108] In some example embodiments, the first configuration information may include one or more of the following: configuration information for the time unit used to monitor the first information; the number of associations between the first information and paging frames; the number of associations between the first information and paging timing; and the number of associations between paging frames and paging timing. In this way, embodiments of this disclosure provide flexible resource configuration capabilities, allowing network devices to dynamically adjust the mapping relationship between wake-up signals and paging resources based on load conditions, coverage requirements, or scheduling strategies, thereby optimizing overall resource utilization and system performance.

[0109] In some example embodiments, the first configuration information may include one or more of the following: first frame information, used to indicate a frame for receiving first information within a paging cycle; first time slot information, used to indicate a time slot for receiving first information within a paging cycle or a frame; and first symbol information, used to indicate a symbol for receiving first information within a paging cycle, a frame, or a time slot. In this manner, embodiments of this disclosure provide the flexible capability to configure the wake-up signal position at multiple time granularities of frames, time slots, and symbols, enabling the network to select time-domain resources for the wake-up signal based on channel conditions, interference avoidance, and resource scheduling requirements. This achieves efficient multiplexing with other system signaling while satisfying reliable detection, thus optimizing overall spectral efficiency.

[0110] In some example embodiments, the first frame information may include one or more of the following: a frame index, used to indicate the frame sequence number used to receive the first information within a paging cycle; a number of frames per paging cycle, used to indicate the number of frames used to receive the first information within a paging cycle; a frame offset, used to indicate the offset between the starting frame and the frame used to receive the first information within a paging cycle; and a frame bitmap, used to indicate the bit sequence of the frames used to receive the first information within a paging cycle. The first timeslot information may include one or more of the following: a timeslot index, used to indicate the timeslot sequence number used to receive the first information within a paging cycle or a frame; a timeslot number per unit frame, used to indicate the number of timeslots used to receive the first information within a paging cycle or a frame; and a timeslot offset, used to indicate the number of timeslots used to receive the first information within a paging cycle. The first symbol information includes: an offset between the starting time slot and the time slot used to receive the first information within a paging cycle or a frame; a time slot bitmap indicating the bits of the time slot used to receive the first information within a paging cycle or a frame; and first symbol information including one or more of the following: a symbol index indicating the symbol number used to receive the first information within a paging cycle, a frame, or a time slot; a number of symbols per unit time slot indicating the number of symbols used to receive the first information within a paging cycle, a frame, or a time slot; a symbol offset indicating the offset between the starting symbol and the symbol used to receive the first information within a paging cycle, a frame, or a time slot; and a symbol bitmap indicating the bits of the bitmap used to receive the first information within a paging cycle, a frame, or a time slot. In this way, embodiments of this disclosure provide various parameterized configuration methods, allowing the network side to select a suitable configuration method based on network configuration and resource utilization to optimize overall network performance.

[0111] In some example embodiments, the first information can be associated with first control information, and the terminal device 110 can also monitor the first information at a first time unit, which can be associated with the paging timing associated with the first control information. In this way, embodiments of this disclosure establish a correlation between the wake-up signal and the target paging timing, realizing the timeliness and targeting of the wake-up indication, enabling the terminal device to monitor the wake-up signal timing relevant to itself, thereby reducing energy consumption.

[0112] In some example embodiments, the terminal device 110 may also be configured to: receive second configuration information for configuring a paging timing, the paging timing being used to monitor first control information; and monitor the first control information at a second time unit, the second time unit being determined based on the second configuration information. In this manner, embodiments of this disclosure define the paging timing using independent second configuration information, enabling network devices to optimize wake-up and paging mechanisms.

[0113] In some example embodiments, the terminal device 110 may also receive first information at a first time unit, which is associated with a reference time unit and a reference time unit offset. The reference time unit may be associated with a second time unit, and the time unit offset may represent the time offset between the first time unit and the reference time unit.

[0114] In some example embodiments, the first information may be received at the first frame, and the first control information may be monitored by the terminal device 110 at the second frame. The first frame may be determined based on a reference frame and a predetermined frame offset. The reference frame may be determined based on one or more of a second frame index and a second paging timing index used by the terminal device to monitor the first control information, and the predetermined frame offset may represent the frame offset between the first frame and the reference frame. In this way, embodiments of the present disclosure enable the terminal device to calculate in advance the timing of monitoring the wake-up signal, providing a basis for achieving deterministic power saving.

[0115] In some example embodiments, the second frame index may be determined based on one or more of the following: terminal device identifier, system frame index of the paging frame, paging frame offset, number of frames in a paging cycle, and number of paging frames in a paging cycle. The second paging timing index is determined based on one or more of the following: terminal device identifier, number of paging frames in a paging cycle, number of paging timings in a paging frame, number of paging timings associated with the first time unit, and paging timing index for the terminal device to monitor first control information within a paging frame. The predetermined frame offset is determined based on one or more of the following: number of paging timings associated with the first time unit, paging timing index for the terminal device to monitor first control information within a paging frame, and number of paging timings within a paging frame. The paging timing index for the terminal device to monitor first control information within a paging frame may be determined based on the terminal device identifier, number of paging frames in a paging cycle, and number of paging timings within a paging frame. In this way, embodiments of this disclosure achieve consistency and correctness in scheduling under multi-user scenarios.

[0116] In some example embodiments, the first information may be associated with multiple frames, and the multiple frames include the first frame. The multiple frames may each be associated with multiple frame offsets, and the multiple frame offsets include a predetermined frame offset. The predetermined frame offset may be determined from the multiple frame offsets based at least on a paging timing index within a paging frame associated with the first frame, used for the terminal device to monitor the first control information. In this way, embodiments of this disclosure support flexible mapping scenarios where a wake-up signal is associated with multiple paging frames, enhancing the flexibility of network devices in handling asymmetric loads and performing resource pooling management.

[0117] In some example embodiments, the first information may be associated with a first number of time units, and the first control information may be associated with a second number of time units. The first and second numbers are positive integers, the first number of time units is used to carry the first information, and the second number of time units is used to monitor the first control information.

[0118] In some example embodiments, the first information may be associated with a first number of frames, and the first control information may be associated with a second number of frames. The first and second numbers are positive integers. The first number of frames are frames used to carry the first information, and the second number of frames are paging frames used to monitor the first control information. In this way, embodiments of this disclosure provide a quantitative mapping relationship between wake-up signal resources and paging resources, achieving a balance between centralized and distributed resource usage, and optimizing coverage and capacity.

[0119] In some example embodiments, the first quantity and the second quantity can be configured as one of the following: the first quantity is 1, the second quantity is 1; the first quantity is 1, the second quantity is 2; the first quantity is 1, the second quantity is 4; the first quantity is 2, the second quantity is 1; the first quantity is 4, the second quantity is 1. In this way, the embodiments of this disclosure cover a variety of application scenarios and provide preset options for network devices to efficiently adapt to different deployment environments and business models.

[0120] In some example embodiments, the terminal device 110 can also obtain a first OFDM-based signal based on the first indication information and the first information. In some example embodiments, the first signal can be obtained based on DFT-s-OFDM or CP-OFDM. In this way, the embodiments of this disclosure use a physical signal structure based on OFDM sequences to carry wake-up information, resulting in low detection complexity. The terminal can use a dedicated low-power receiver or the energy efficiency mode of the main receiver for monitoring, thereby achieving higher energy efficiency gains.

[0121] In some example embodiments, the first signal may be obtained based on encoding and sequence mapping of the first indication information and the first information. The encoding process may be based on Polar codes or Reed-Muller codes. The sequence mapping process may include one or more of the following: Zadoff-Chu sequences, Kasami sequences, Gold sequences, m sequences, and Walsh sequences. In some example embodiments, the encoding may also include rate matching and / or cyclic redundancy check (CRC) processing. In this way, embodiments of this disclosure provide a method for generating OFDM symbols carrying wake-up signals, providing a foundation and multiple options for the implementation of this disclosure. The network side can select an appropriate generation method according to the application scenario.

[0122] In some example embodiments, the first signal may be obtained based on first indication information, first information, and a cyclic redundancy check (CRC) bit. The CRC check length may include one of 8 bits, 16 bits, or 24 bits. In this way, embodiments of this disclosure provide an optional range of CRC check lengths, allowing network devices to flexibly select the check strength according to the requirements for wake-up reliability and the availability of resources, further realizing a configurable trade-off between reliability and efficiency.

[0123] In some example embodiments of this disclosure, DL-WUS can employ a signal structure based on OFDM sequences. Specifically, the signal can be further divided into two implementations: DL-WUS based on DFT-s-OFDM and DL-WUS based on CP-OFDM.

[0124] Figure 2B Another schematic signaling interaction diagram of a communication process according to some embodiments of this disclosure is shown. For convenience, reference will be made to... Figure 1 The following example is used to describe the communication process 200B. The communication process 200A may involve terminal device 110 and network device 120.

[0125] like Figure 2B As shown, at position 255, terminal device 110 can receive first configuration information from network device 120. The first configuration information may include one or more of the following: configuration information for time units used to monitor the first information; the number of associations between the first information and paging frames; the number of associations between the first information and paging timings; and the number of associations between paging frames and paging timings. The first configuration information may also include one or more of the following: first frame information, used to indicate frames used to receive the first information within a paging cycle; first time slot information, used to indicate time slots used to receive the first information within a paging cycle or a frame; and first symbol information, used to indicate symbols used to receive the first information within a paging cycle, a frame, or a time slot. Terminal device 110 can then monitor the first information at the first time unit. The first time unit is determined based on the first configuration information.

[0126] At point 260, terminal device 110 can receive first indication information and first information. The first indication information is used to indicate the indication method associated with the first information, and the first information is used to indicate whether the terminal device monitors first control information related to paging. At point 265, terminal device 110 can determine whether to monitor first downlink control information based on the first indication information and the first information.

[0127] At point 270, based on the determination to monitor the first control information, terminal device 110 can monitor the first control information at a paging timing associated with the first information. The first control information may include second indication information used to indicate a paging message. Then, based on the second indication information, terminal device 110 can receive a paging message sent by network device 120. In other embodiments, based on the determination not to monitor the first control information, the first control information is not monitored.

[0128] Figure 3 A schematic diagram of an example generation process 300 of DL-WUS based on DFT-s-OFDM according to some embodiments of the present disclosure is shown. For convenience, reference will be made to... Figure 1 The following example illustrates the communication process 300. The communication process 300 may involve terminal device 110 and network device 120.

[0129] like Figure 3 As shown, WUS information may include a UE paging indication field and a WUS information type indication field. In some example embodiments, the length of the WUS information type indication field may be 1 bit.

[0130] The encoding may include channel coding. In some example embodiments, polar codes may be used for encoding. In some example embodiments, Reed-Muller codes may be used for encoding. In some example embodiments, the encoding may include rate matching. In some example embodiments, the encoding may not include rate matching. In some example embodiments, the encoding may include cyclic redundancy check (CRC). In some example embodiments, the CRC length may be 8 bits. In some example embodiments, the CRC length may be 16 bits. In some example embodiments, the CRC length may be 24 bits. In some example embodiments, the encoding may not include CRC.

[0131] In some example implementations, S / P stands for serial-to-parallel conversion for subsequent sequence mapping.

[0132] In some example embodiments, the sequence in the sequence mapping can be a ZC sequence (Zadoff-Chu sequence). In some example embodiments, the sequence in the sequence mapping can be a pseudo-random sequence. In some example embodiments, the sequence in the sequence mapping can be an m-sequence. In some example embodiments, the sequence in the sequence mapping can be a Gold sequence. In some example embodiments, the sequence in the sequence mapping can be a Kasami sequence. In some example embodiments, the sequence in the sequence mapping can be a Walsh sequence.

[0133] Sequence mapping methods can represent information bits using different sequences. In some example embodiments, when carrying 2 bits of information, if four optional sequences are configured, the bit "00" can be mapped to sequence c1, "01" to c2, "11" to c3, and "10" to c4. In some example embodiments, for ZC sequences, different sequences can be generated by selecting different root sequences or by performing a cyclic shift on the same root sequence.

[0134] Each sequence undergoes a DFT and, together with other signals, generates OFDM symbols for transmission to the terminal device.

[0135] The above example implementation is DL-WUS based on DFT-s-OFDM. Its advantage is that the sequence is a time-domain signal, and the UE receiver only needs to perform correlation operations, without having to perform fast fourier transform (FFT) operations, resulting in lower computational complexity.

[0136] Figure 4 A schematic diagram illustrating an example generation process of CP-OFDM-based DL-WUS according to some embodiments of this disclosure is shown. For convenience, reference will be made to... Figure 1 The following example illustrates the communication process 400. The communication process 400 may involve terminal device 110 and network device 120.

[0137] like Figure 4 As shown, WUS information, encoding, S / P, sequence mapping and Figure 3 Similar examples are shown below and will not be repeated here. Figure 4 The advantage of the method shown is that the transmitter does not need to perform DFT calculations; each sequence can be directly combined with other signals to generate OFDM symbols for transmission to the UE. The low-power receiver or energy-efficient mode at the UE can reuse the FFT module without significantly increasing energy consumption.

[0138] It should be noted that, Figure 3 and Figure 4 The implementation method described herein is merely an exemplary embodiment. Any technical solution that carries downlink wake-up signal information on OFDM sequence-based signals is possible, and is not limited to the specific implementation described herein. Furthermore, any suitable method for carrying WUS based on OFDM sequences is within the scope of this disclosure.

[0139] Figure 5 A schematic diagram of an example time-domain location of DL-WUS according to some embodiments of the present disclosure is shown. For convenience, reference will be made to... Figure 1 The following example illustrates schematic diagram 500. Schematic diagram 500 may involve terminal device 110 and network device 120.

[0140] like Figure 5 As shown, taking a paging period of T=16 frames as an example, a DL-WUS frame can be associated with one paging frame (PF), for example, DL-WUS2 is associated with PF2. A DL-WUS frame can contain 3 DL-WUS occasions (DOs or DL-WUS-Os), one DO can represent one time slot, and one DO can contain 6 WUS symbols. A PF (e.g., PF2) can contain 4 paging occasions (POs), and each paging occasion can contain several symbols (not shown in the figure). The number of POs associated with a DO can be the number of POs within the PF frame associated with the DO; therefore, the DO in DL-WUS2 is associated with 4 POs, i.e. This parameter is configured by network device 120.

[0141] DL-WUS2 involves three time slots, a value that can be indicated by network device 120 through a higher-layer parameter configuration bitmap. In some example embodiments, the bitmap "0100011000" can be configured to indicate a time slot where WUS may exist. Within a time slot, the network device 120 can indicate the symbol of WUS within the time slot through the higher-layer parameter configuration bitmap "01010100001110". In this way, UE 110 can detect WUS at the configured symbols with low complexity.

[0142] In some example embodiments, a parameter can be configured by network device 120 via higher-layer parameters to indicate the number of DL-WUS symbols in a specific timeslot containing DL-WUS-O. Figure 5 In the example, this parameter is 6. UE110 determines which symbols are occupied based on other relevant configuration parameters. The UE can determine whether a symbol is a DL-WUS symbol by only detecting unoccupied symbols. In some example embodiments, other relevant configuration parameters may be symbols configured for uplink transmission, symbols configured for synchronization signal transmission, etc. In this way, resource utilization can be more flexible because the symbol sequence number for WUS within each time slot can be different, and network device 120 can flexibly schedule according to the actual situation.

[0143] In some example embodiments, a parameter can be configured by network device 120 via higher-layer parameters to indicate the offset between the start symbol and the first WUS symbol of the DL-WUS frame. For example, in Figure 5 In this frame, the offset between the starting symbol and the first WUS symbol is 1 slot + 1 symbol, so this parameter represents 15 symbols.

[0144] From the UE's perspective, UE 110 can determine which PO in which PF it should monitor in each paging cycle based on its paging-related configuration.

[0145] In summary, network device 120 can indicate the frame number of the DL-WUS frame for UE 110 using configured network parameters. In some example embodiments, the frame number of the DL-WUS frame can be indicated by a reference frame plus an offset, which can be referred to in conjunction with... Figure 6 The UE can obtain the frame number of the DL-WUS associated with the PO that needs to be monitored, as well as the slot location where the WUS may exist in that frame. The UE can detect the WUS symbol in that slot to obtain indication information.

[0146] It should be noted that the above embodiments are merely examples. Network device 120 can configure all relevant parameters, or it can select some parameters for configuration. Parameters such as paging period T, the frame and number of DL-WUS, the associated PF and number, the time slots and number covered by DL-WUS-O, the time slots and number covered by PO, the symbols and number of WUS, and the association between DL-WUS and PF are described for the purpose of understanding this disclosure and do not represent recommended parameter combinations. Any other suitable parameter combination is possible and can be flexibly configured according to the dynamic changes of the network, and all are within the scope of this disclosure.

[0147] In some example embodiments, the indication information in WUS may include WUS information type identification information, also known as first indication information, to inform the UE of the meaning of subsequent indication information. In some example embodiments, the identification information is represented by 1 bit. In some example embodiments, an identification information of 1 indicates that subsequent information is a subgroup indication in groups of X bits, where the value of X bits represents the subgroup number, and X is configured by higher-layer parameters of the network device; an identification information of 0 indicates that subsequent information is a bit stream indication, where the position of each bit indicates a subgroup, and the bit value indicates whether the subgroup needs to initiate paging signal monitoring. In some example embodiments, when subsequent indication information in WUS is indicated in the form of a bit stream, it can be agreed that 1 indicates that the UE indicated by that bit position in the current paging cycle needs to initiate paging signal monitoring, and 0 indicates that the UE does not need to initiate paging signal monitoring in the current paging cycle.

[0148] Here are some specific examples, assuming the bitstreams obtained by the UE after decoding WUS twice are as follows: “1 00000 00001 00010 00011 00100 00101” “0 00000 00001 00010 00011 00100 00101” As can be seen, apart from the identification information represented by the first bit, the subsequent bit streams are completely identical. However, due to the different identification information represented by the first bit, the UE can interpret the information in the subsequent bit streams differently.

[0149] In some example embodiments, if the identification information is 1, the UE can interpret the subsequent information as indicating a subgroup in groups of 5 bits (depending on the higher-layer parameter configuration, X bits can be selected as 1 group). For example, 00000 represents subgroup 0, and 00001 represents subgroup 1. Therefore, the UE can interpret the information as follows: UEs belonging to subgroups 0, 1, 2, 3, 4, and 5 need to initiate paging-related downlink control information monitoring, while UEs belonging to other subgroups do not monitor paging-related downlink control information in the PO associated with this WUS. In some example embodiments, the UE can know which subgroup it belongs to based on its own UE identifier (ID), and thus determine whether it needs to monitor paging-related downlink control information in the corresponding PO.

[0150] It should be noted that the grouping of 5 bits can depend on the network-side higher-layer configuration, which can configure any suitable X value. Furthermore, in some example embodiments, a group of bits may not necessarily indicate only one subgroup; a specific bit sequence can be specified to represent a specific meaning. For example, 11111 represents that all UEs in all subgroups need to initiate paging-related downlink control information monitoring.

[0151] In some example embodiments, if the identifier information is 0, the UE can assume that UEs in subgroups 9 (10th bit in the bitstream is 1), 13 (14th bit in the bitstream is 1), 18, 19, 22, 27, and 29 need to initiate paging signal monitoring. UEs belonging to other subgroups do not monitor paging-related downlink control information in the PO associated with that WUS. In some example embodiments, the UE can know which subgroup it belongs to based on its own UE ID, and thus determine whether it needs to monitor paging-related downlink control information in the corresponding PO.

[0152] In some example embodiments, the UE can calculate its own subgroup ID in the following way: (1) in Indicates the UE identifier. This indicates the number of PFs contained within a paging cycle. This indicates the number of Product Objects (POs) contained within a Product Function (PF). This indicates the number of subgroups in a single PO when subgrouping is based on UE ID. For example, for 5G PEI, The maximum value can be 8, for 5G LP-WUS, The maximum value can be 31. All of the above parameters can be configured by network parameters, or calculated by parameters configured by the network.

[0153] In some example embodiments, the UE ID can be calculated in the following way: ,in This indicates the temporary identifier of the UE in the core network. The specific value can be agreed upon by the network side and the terminal side. For example, for 5G, The value can be 1024, 4096, 8192, 32768, 1048576, etc., depending on the application scenario.

For convenience, reference will be made to... Figure 1 The following example illustrates schematic diagram 600. Schematic diagram 600 may involve terminal device 110 and network device 120.

[0155] like Figure 6 As shown, taking a paging period of T=16 frames as an example. Example 1 is... That is, the number of POs associated with a DO is equal to the number of POs in a PF. Macroscopically, this means that a DL-WUS frame is associated with a PF, for example, DL-WUS1 is associated with PF1.

[0156] Example 2 is That is, the number of POs associated with DO is equal to the number of POs in 2 PFs. Macroscopically, this means that one DL-WUS frame is associated with two PFs, such as DL-WUS1 being associated with PF2 and PF3.

[0157] Example 3 is That is, the number of POs associated with DO is equal to the number of POs in the 4 PFs. Macroscopically, this means that one DL-WUS frame is associated with 4 PFs, for example, DL-WUS0 is associated with PF0 to PF3.

[0158] Example 4 is 2 That is, the number of POs associated with 2 DOs is equal to the number of POs in 1 PF. Macroscopically, this is manifested as 2 DL-WUS frames being associated with 1 PF, such as DL-WUS2 and DL-WUS3 being associated with PF1.

[0159] Example 5 is 4 That is, the number of POs associated with 4 DOs is equal to the number of POs in 1 PF. Macroscopically, this is manifested as 4 DL-WUS frames being associated with 1 PF, for example, DL-WUS0 to DL-WUS3 being associated with PF1.

[0160] Network device 120 can configure the number of POs associated with DO to UE 110. Relevant parameters. Based on its paging configuration, UE 110 can determine which PO within which PF it should monitor for paging messages during each paging cycle. In some example embodiments, UE 110 can calculate the sequence number of the PO to be monitored within the PO associated with the DO in the following way: (2) in It is the UE identifier. This indicates the number of PFs within a paging cycle. Indicates the number of POs within the PF. This indicates the index of the PO within its PF, and also the sequence number of the PO that the UE needs to monitor within its PF.

[0161] UE calculates its own Subsequently, the corresponding DO time domain position is determined by the time offset configured by the network. The given value represents the time distance between the DO and the reference paging frame. In some example embodiments, the frame number of the reference paging frame can be calculated using the following formula: (3) in This indicates the system frame number of the paging frame to which the UE belongs. It is the number of frames in a paging cycle.

[0162] Here are some specific examples, assuming... The frame, i.e., the frame containing DL-WUS, has a frame number difference of 6 with its nearest associated PF. Assume... The number of PFs in one paging cycle is The number of POs within a PF is It can be calculated Furthermore, assuming ,therefore , corresponding to Figure 6 Example 2.

[0163] In some example embodiments, the UE is configured to monitor the PO, assuming the UE calculates that it should monitor the PF with frame number 10 (i.e., Based on the paging-related parameters and calculation process described above, the UE can calculate the sequence number of the PF that should be monitored. PO. Therefore, we can calculate... , Therefore, the UE can calculate that its DL-WUS is located in frame number [frame number missing]. On the frame, such as Figure 6 The DL-WUS0 shown in Example 2.

[0164] For the scenario shown in Example 4, since Furthermore, DOs can belong to different frames, therefore multiple different network parameter configurations are required. The UE can select different options based on the sequence number of the PO in the frame. In some example embodiments, the serial number can be... calculate.

[0165] The following are some specific examples, assuming the UE is configured. and Two parameters, The number of PFs in one paging cycle is The number of POs within a PF is It can be calculated Furthermore, assuming ,therefore .

[0166] In some example embodiments, the UE is configured to monitor PO; therefore, according to the above parameters, the monitoring sequence number should be [number to be filled in]. The sequence number in the PF is The PO, i.e., PO3 in PF2. Therefore, the UE can be selected from two... Select the serial number as of ,Right now For simplicity, we can assume that PF2's frame number is 14, i.e. Therefore, it can be calculated that... , Therefore, the UE can calculate that its DL-WUS is located in frame number [frame number missing]. On the frame, such as Figure 6 The DL-WUS5 shown in Example 4.
