Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication, in particular to a communication method and a communication device. BACKGROUND

[0002] Physical downlink control channel (PDCCH) blind detection is a necessary process for terminal devices to obtain uplink and downlink scheduling information. In this process, the terminal device needs to perform PDCCH blind detection in a preset control resource set (CORESET) using predetermined rules, which will result in a large number of PDCCH blind detections and thus a large overall power consumption of the terminal device in PDCCH blind detection.

[0003] Therefore, how to reduce the overall power consumption of the terminal device in PDCCH blind detection is a technical problem to be solved at present. SUMMARY

[0004] The present application provides a communication method and a communication device, which can reduce the overall power consumption of the terminal device in PDCCH blind detection.

[0005] In a first aspect, a communication method is provided, which includes: receiving first information from a network side device, the first information indicating related information of M low power consumption wake-up signal monitoring occasions; and monitoring a low power consumption wake-up signal on N low power consumption wake-up signal monitoring occasions according to the first information, the low power consumption wake-up signal indicating whether to perform PDCCH blind detection, the N low power consumption wake-up signal monitoring occasions being related to the M low power consumption wake-up signal monitoring occasions, M and N being positive integers.

[0006] The solution of the first aspect can be executed by a terminal side device, which can be a terminal device, a functional module (such as a chip system or an integrated circuit, etc.), or a logic node, a logic module or software capable of realizing all or part of the functions of the terminal device. For ease of description, the terminal device is taken as an example in the following description.

[0007] In the scheme, the terminal device can determine the M low-power wake-up signal monitoring occasions according to the first information, and determine the N low-power wake-up signal monitoring occasions according to the M low-power wake-up signal monitoring occasions, and monitor the low-power wake-up signal for indicating whether to perform PDCCH blind detection on the N low-power wake-up signal monitoring occasions. In this way, the terminal device does not need to monitor the low-power wake-up signal on each low-power wake-up signal monitoring occasion, which can effectively reduce the number of times of monitoring the low-power wake-up signal by the terminal device, thereby being able to reduce the overall power consumption of the terminal device for performing PDCCH blind detection, for example, the overhead of the terminal device for monitoring the low-power wake-up signal can be reduced, thereby being able to reduce the overall power consumption of the terminal device when performing PDCCH blind detection.

[0008] In some implementations of the first aspect, before receiving the first information from the network-side device, the method further includes: receiving second information from the network-side device, the second information configuring one or more low-power wake-up signal monitoring occasion configurations, the first low-power wake-up signal monitoring occasion configuration being one of the one or more low-power wake-up signal monitoring occasion configurations.

[0009] In this way, the terminal device can select the first low-power wake-up signal monitoring occasion configuration from the one or more low-power wake-up signal monitoring occasions configured by the network device according to the first information, which can support the terminal device to monitor the low-power wake-up signal on part of the low-power wake-up signal monitoring occasions, thereby being able to support reducing the overall power consumption of the terminal device when monitoring the low-power wake-up signal, and further being able to reduce the overall power consumption of the terminal device when performing PDCCH blind detection.

[0010] In a second aspect, a communication method is provided, including: determining first information, the first information indicating related information of M low-power wake-up signal monitoring occasions; and sending the first information to a terminal-side device, the first information being used by the terminal-side device to monitor a low-power wake-up signal on N low-power wake-up signal monitoring occasions, the low-power wake-up signal indicating whether to perform physical downlink control channel blind detection, the N low-power wake-up signal monitoring occasions being related to the M low-power wake-up signal monitoring occasions, M and N being positive integers.

[0011] The scheme of the second aspect can be performed by a network-side device, which can be a network device, or a functional module (such as a chip system or an integrated circuit, etc.), or a logic node, a logic module or software, etc. that can implement all or part of the functions of the network device. For ease of description, the network device is taken as an example for description hereinafter.

[0012] In the scheme, the network device sends first information used for indicating M low-power wake-up signal monitoring occasions to the terminal device, and the first information can be used by the terminal device to determine N low-power wake-up signal monitoring occasions used for monitoring the low-power wake-up signal, thereby reducing the number of times of monitoring the low-power wake-up signal by the terminal device, and further supporting reducing the overall power consumption of the terminal device when performing PDCCH blind detection.

[0013] In some implementations of the second aspect, the method further includes: sending second information to the terminal-side device, the second information configuring one or more low-power wake-up signal monitoring occasion configurations, and the first low-power wake-up signal monitoring occasion configuration being one of the one or more low-power wake-up signal monitoring occasion configurations.

[0014] In this way, the network device can configure one or more low-power wake-up signal monitoring occasion configurations for the terminal device.

[0015] In combination with any of the first aspect and the second aspect, the first information indicates related information of the M low-power wake-up signal monitoring occasions, including: the first information indicates a first low-power wake-up signal monitoring occasion configuration, and the low-power wake-up signal monitoring occasions configured by the first low-power wake-up signal monitoring occasion configuration include the M low-power wake-up signal monitoring occasions; or the first information indicates positions of the M low-power wake-up signal monitoring occasions.

[0016] When the first information indicates the first low-power wake-up signal monitoring occasion configuration, the terminal device can determine the M low-power wake-up signal monitoring occasions according to the first low-power wake-up signal monitoring occasion configuration, which can reduce signaling overhead.

[0017] When the first information directly indicates the positions of the M low-power wake-up signal monitoring occasions, this can reduce the processing power consumption of the terminal device for determining the M low-power wake-up signal monitoring occasions.

[0018] In combination with any of the first aspect and the second aspect, the N low-power wake-up signal monitoring occasions are the same as the M low-power wake-up signal monitoring occasions, including: the N low-power wake-up signal monitoring occasions are the same as the M low-power wake-up signal monitoring occasions.

[0019] In this way, the terminal device can directly monitor the low-power wake-up signal on the M low-power wake-up signal monitoring occasions.

[0020] In combination with any of the first aspect and the second aspect, the N low-power wake-up signal monitoring occasions are the same as the M low-power wake-up signal monitoring occasions, and the first information indicates a first low-power wake-up signal monitoring occasion configuration, including any of the following:

[0021] The first information indicates that the first low-power wake-up signal monitoring occasion configuration is activated;

[0022] The first information indicates switching from the second low-power wake-up signal monitoring occasion configuration to the first low-power wake-up signal monitoring occasion configuration, the second low-power signal monitoring occasion configuration is K low-power wake-up signal monitoring occasions, and the K low-power wake-up signal monitoring occasions are different from the M low-power wake-up signal monitoring occasions.

[0023] The first information indicates monitoring a low-power wake-up signal monitoring occasion configured by the first low-power wake-up signal monitoring occasion configuration.

[0024] The first information indicates not skipping monitoring a low-power wake-up signal monitoring occasion configured by the first low-power wake-up signal monitoring occasion configuration.

[0025] In this way, the terminal device can determine the low-power wake-up signal monitoring occasion in which the low-power wake-up signal needs to be monitored according to any one of the above.

[0026] In combination with any one of the first aspect and the second aspect, the N low-power wake-up signal monitoring occasions are related to the M low-power wake-up signal monitoring occasions, including that the N low-power wake-up signal monitoring occasions are different from the M low-power wake-up signal monitoring occasions.

[0027] In this way, the terminal device can determine the M low-power wake-up signal monitoring occasions in which the low-power wake-up signal does not need to be monitored, and thus the number of times of monitoring the low-power wake-up signal by the terminal device can be reduced.

[0028] In combination with any one of the first aspect and the second aspect, the M low-power wake-up signal monitoring occasions are different from the N low-power wake-up signal monitoring occasions, and the first information indicates the first low-power wake-up signal monitoring occasion configuration, including any one of the following:

[0029] The first information indicates deactivating the first low-power wake-up signal monitoring occasion configuration.

[0030] The first information indicates releasing the first low-power wake-up signal monitoring occasion configuration.

[0031] The first information indicates not monitoring a low-power wake-up signal monitoring occasion configured by the first low-power wake-up signal monitoring occasion configuration.

[0032] The first information indicates skipping monitoring a low-power wake-up signal monitoring occasion configured by the first low-power wake-up signal monitoring occasion configuration.

[0033] In this way, the terminal device can determine the low-power wake-up signal monitoring occasion in which the low-power wake-up signal does not need to be monitored according to any one of the above.

[0034] In combination with any one of the first aspect and the second aspect, the first information is carried in a low-power signal.

[0035] Thus, the power consumption of the network device can be reduced.

[0036] In a third aspect, a communication method is provided, including: determining, according to a first event, a first low-power wake-up signal monitoring occasion configuration, the first low-power wake-up signal monitoring occasion configuration being used to configure M low-power wake-up signal monitoring occasions; and monitoring, on N low-power wake-up signal monitoring occasions, a low-power wake-up signal, the low-power wake-up signal indicating whether to perform physical downlink control channel blind detection, the N low-power wake-up signal monitoring occasions being related to the M low-power wake-up signal monitoring occasions, M and N being positive integers; the first event including at least one of a sending state of uplink information, a state of a timer related to monitoring the low-power wake-up signal, and a state of the terminal-side device.

[0037] The solution of the third aspect can be implemented by a terminal-side device, which can be a terminal device, a functional module (such as a chip system or an integrated circuit, etc.), or a logic node, a logic module, or software, etc. that can implement all or part of the functions of the terminal device. For ease of description, the terminal device is described below as an example.

[0038] In the above solution, the terminal device can determine the first low-power wake-up signal monitoring occasion configuration according to the first event, and can determine the N low-power wake-up signal monitoring occasions on which the low-power wake-up signal needs to be monitored according to the first low-power wake-up signal monitoring occasion configuration. Thus, the terminal device does not need to directly determine the N low-power wake-up signal monitoring occasions according to the indication of the network device, which can reduce the signaling interaction overhead between the terminal device and the network device. In addition, the terminal device only needs to monitor the low-power wake-up signal on part of the low-power wake-up signal monitoring occasions, which can effectively reduce the number of times of monitoring the low-power wake-up signal by the terminal device, thereby reducing the overall power consumption of the terminal device for monitoring the low-power wake-up signal.

[0039] In some implementations of the third aspect, the uplink information includes at least one of: a scheduling report, a buffer status report, a message 1, a message 3, a message A, terminal device activation information, or information used to indicate the first low-power wake-up signal monitoring occasion configuration.

[0040] Thus, the terminal device can determine the first low-power wake-up signal monitoring occasion configuration according to the sending state of the above information.

[0041] In some implementations of the third aspect, the state of the timer includes any one of: normal, invalid, timeout, or expired.

[0042] Thus, the terminal device can determine the first low-power wake-up signal monitoring occasion configuration according to the state of the above timer.

[0043] In some implementations of the third aspect, the state of the terminal-side device comprises any one of: contention resolution is completed, a random access response is successfully received, uplink scheduling is not needed, or a low-power wake-up signal detection is not needed.

[0044] In this way, the terminal device can determine the first low-power wake-up signal monitoring occasion configuration according to the state of the terminal-side device.

[0045] In some implementations of the third aspect, the N low-power wake-up signal monitoring occasions are related to the M low-power wake-up signal monitoring occasions, comprising: the N low-power wake-up signal monitoring occasions are the same as the M low-power wake-up signal monitoring occasions.

[0046] In this way, the terminal device can directly monitor the low-power wake-up signal on the M low-power wake-up signal monitoring occasions.

[0047] In some implementations of the third aspect, the N low-power wake-up signal monitoring occasions are the same as the M low-power wake-up signal monitoring occasions, and the determining the first low-power wake-up signal monitoring occasion configuration comprises any one of:

[0048] activating the first low-power wake-up signal monitoring occasion configuration;

[0049] switching from a second low-power wake-up signal monitoring occasion configuration to the first low-power wake-up signal monitoring occasion configuration, the second low-power signal monitoring occasion configuration comprising K low-power wake-up signal monitoring occasions, and the K low-power wake-up signal monitoring occasions being different from the M low-power wake-up signal monitoring occasions;

[0050] monitoring the low-power wake-up signal monitoring occasions configured by the first low-power wake-up signal monitoring occasion configuration; or

[0051] not skipping monitoring the low-power wake-up signal monitoring occasions configured by the first low-power wake-up signal monitoring occasion configuration.

[0052] In this way, the terminal device can determine the low-power wake-up signal monitoring occasions on which the low-power wake-up signal needs to be monitored according to any one of the above.

[0053] In some implementations of the third aspect, the N low-power wake-up signal monitoring occasions are related to the M low-power wake-up signal monitoring occasions, comprising: the N low-power wake-up signal monitoring occasions are different from the M low-power wake-up signal monitoring occasions.

[0054] In this way, the terminal device can determine the M low-power wake-up signal monitoring occasions on which the low-power wake-up signal does not need to be monitored, and thus the number of times of monitoring the low-power wake-up signal by the terminal device can be reduced.

[0055] In some implementations of the third aspect, the N low-power wake-up signal monitoring occasions are different from the M low-power wake-up signal monitoring occasions, and the determining the first low-power wake-up signal monitoring occasion configuration comprises any one of the following:

[0056] deactivating the first low-power wake-up signal monitoring occasion configuration;

[0057] releasing the first low-power wake-up signal monitoring occasion configuration;

[0058] not monitoring a low-power wake-up signal monitoring occasion configured by the first low-power wake-up signal monitoring occasion configuration; or

[0059] skipping monitoring a low-power wake-up signal monitoring occasion configured by the first low-power wake-up signal monitoring occasion configuration.

[0060] In this way, the terminal device can determine a low-power wake-up signal monitoring occasion in which the low-power wake-up signal does not need to be monitored according to any one of the above.

[0061] In some implementations of the third aspect, the method further comprises receiving configuration information from a network-side device, the configuration information being used to configure one or more low-power wake-up signal monitoring occasion configurations, and the first low-power wake-up signal monitoring occasion configuration being one of the one or more low-power wake-up signal monitoring occasion configurations.

[0083] In order to facilitate understanding of the embodiments of the present application, the following points are first explained.

[0084] I. Unless otherwise stated, the meaning of "a plurality of" is two or more. "At least one" means "one or more".

[0085] II. If there is no special description and logical conflict, the terms and / or descriptions of different embodiments of the present application are consistent and can be mutually referred to. The technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationship.

[0086] Third, the various numbers in the present application only serve as a convenient distinction and do not serve to limit the scope of protection of the present application. The size of the serial numbers in the present application does not mean the order of execution, and the execution order of each process should be determined according to its function and inherent logic. For example, the terms "first", "second", "third", "fourth" and other various term labels in the specification and claims of the present application and the drawings (if any) are used to distinguish similar objects and do not necessarily describe a specific order or sequence. Among them, the data thus used can be interchanged under appropriate circumstances, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein.

[0087] At the same time, any embodiment or design scheme described as "exemplary" or "for example" in the present application should not be interpreted as more preferred or more advantageous than other embodiments or design schemes. Rather, the use of "exemplary" or "for example" and the like is intended to present the relevant concept in a specific manner for ease of understanding.

[0088] Fourth, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0089] Fifth, in the present application, "for indicating" can be understood as "enabling", and "enabling" includes direct enabling and indirect enabling. When describing that a certain information is used to enable A, it can include that the information directly enables A or indirectly enables A, and it does not mean that A must be carried in the information.

[0090] The information enabled by the information is called to-be-enabled information, and there are many ways to enable the to-be-enabled information in the implementation process, for example, but not limited to, the to-be-enabled information can be directly enabled, such as the to-be-enabled information itself or the index of the to-be-enabled information. The to-be-enabled information can also be indirectly enabled by enabling other information, where the other information and the to-be-enabled information have an association relationship. The to-be-enabled information can also be enabled only for a part, and the other part of the to-be-enabled information is known or agreed in advance. For example, the enabling of a specific information can also be realized by means of the arrangement order of each information agreed in advance (such as a protocol), thereby reducing the enabling overhead to a certain extent. At the same time, the common part of each information can be identified and uniformly enabled to reduce the enabling overhead caused by enabling the same information separately.

[0091] In addition, the indication can include direct indication, indirect indication, display indication, and implicit indication. When it is described that certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0092] In the present application, the information indicated by the indication information is referred to as the to-be-indicated information. In the specific implementation process, there are many ways to indicate the to-be-indicated information, for example, but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or the index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be indicated only by a part of the to-be-indicated information, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can also be achieved by means of the arrangement order of each information agreed in advance (for example, the protocol stipulates), thereby reducing the indication overhead to a certain extent. In addition, the to-be-indicated information can be sent as a whole, or can be sent separately in multiple sub-information, and the sending period and / or sending time of these sub-information can be the same or different.

[0093] Sixthly, in the present application, the pre-configuration can include pre-definition, for example, protocol definition. The pre-definition can be achieved by pre-saving the corresponding code, table or other information indicating manner in the device (for example, including various network elements), and the present application does not limit the specific implementation manner thereof.

[0094] Seventhly, the storage or saving referred to in the present application can be saved in one or more memories. The one or more memories can be separately arranged or integrated in the encoder or decoder, processor, or communication device. The one or more memories can be partially separately arranged and partially integrated in the decoder, processor, or communication device. The type of memory can be any form of storage medium, which is not limited.

[0095] Eighthly, the protocol referred to in the present application can refer to a standard protocol in the communication field, for example, can include a fourth generation (4th generation, 4G) network, a fifth generation (5th generation, 5G) network protocol, a 5.5G network protocol, and a related protocol applied to a future communication network, which is not limited in the present application.

[0096] Ninthly, the arrows or blocks shown by the dashed lines in the schematic diagram of the drawing part of the present application specification represent optional steps or optional modules.

[0097] 10. Unless otherwise stated, " / " indicates that the objects before and after are in an "or" relationship. For example, A / B can mean A or B. In this application, "and / or" is merely a description of the relationship between the related objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. A and B can be singular or plural.

[0098] XI. In this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include direct transmission via the air interface or indirect transmission by other units or modules via the air interface. "Receive information from YY" can be understood as the source of the information being YY, which may include direct reception from YY via the air interface or indirect reception from YY by other units or modules via the air interface. "Send" can also be understood as the "output" of a chip interface, and "receive" can also be understood as the "input" of a chip interface. In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via a bus, wiring, or interface.

[0099] First, the communication system to which the embodiments of this application are applicable will be described.

[0100] Figure 1 This is a schematic diagram of a communication system to which embodiments of this application apply. For example... Figure 1 As shown, the communication system includes a radio access network (RAN) 100 and a core network (CN) 200. RAN 100 includes at least one RAN node (such as 110a and 110b, collectively referred to as 110) and at least one terminal device (such as 120a-120j, collectively referred to as 120). RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices. Figure 1 (Not shown). Terminal device 120 is connected to RAN node 110 wirelessly. RAN node 110 is connected to CN200 wirelessly or via wired connection. The core network equipment in CN200 and RAN node 110 in RAN 100 can be different physical devices, or they can be the same physical device integrating CN logical functions and RAN logical functions.

[0101] The RAN 100 can be a 3rd generation partnership project (3GPP) related cellular system, e.g., a 4G, 5G communication system or a future communication system. The RAN 100 can also be an open radio access network (O-RAN or ORAN), a cloud radio access network (C-RAN or CRAN), a wireless fidelity (Wi-Fi) system. The RAN 100 can also be a communication system in which two or more of the above systems are fused.

[0102] The RAN node 110, which can also be referred to as an access network device, a RAN entity, or an access node, etc., is configured to help terminal devices to access a wireless access. The RAN nodes 110 in the communication system 100 can be of the same type or of different types. In some scenarios, the roles of the RAN node 110 and the terminal device 120 are relative, e.g., the network element 120i can be a helicopter or a drone, which can be configured to be a mobile base station. For a terminal device 120j accessing to the RAN 100 through the network element 120i, the network element 120i is a base station. But for the base station 110a, the network element 120i is a terminal device. The RAN nodes 110 and the terminals 120 are sometimes referred to as communication apparatuses, e.g., the network elements 110a and 110b can be understood as communication apparatuses with base station functionalities, and the network elements 120a-120j can be understood as communication apparatuses with terminal functionalities.

[0103] In a possible scenario, the RAN node can be a base station (BS), an evolved NodeB (eNB), an access point (AP), a transmission point (TP), a transmission reception point (TRP), a next generation NodeB (gNB), a future communication network node, or an access node in a Wi-Fi system, etc. The RAN node can be a macro base station (like the 110a in FIG. 1), a micro base station or an indoor station (like the 110b in FIG. 1), a relay node or a donor node, or a wireless controller in a CRAN scenario. Figure 1 Figure 1 In a possible scenario, the RAN node can be a base station (BS), an evolved NodeB (eNB), an access point (AP), a transmission point (TP), a transmission reception point (TRP), a next generation NodeB (gNB), a future communication network node, or an access node in a Wi-Fi system, etc. The RAN node can be a macro base station (like the 110a in FIG. 1), a micro base station or an indoor station (like the 110b in FIG. 1), a relay node or a donor node, or a wireless controller in a CRAN scenario.

[0104] ​The RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. All or part of the functions of the RAN node in this application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform, such as a cloud platform. The RAN node in this application can also be a logical node, a logical module or software that can realize all or part of the functions of the RAN node.

[0105] In another possible scenario, multiple RAN nodes cooperate to assist terminal devices to implement wireless access, and different RAN nodes respectively implement part of the functions of a base station. For example, a RAN node can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna processing unit (AAU), or a remote radio head (RRH).

[0106] In different communication systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, in an ORAN system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. For the sake of convenience, the CU, CU-CP, CU-UP, DU and RU are taken as examples for description in this application. Any one of the CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0114] In this embodiment, the communication device used to implement the functions of the network device can be the network device itself, or it can be a device that supports the network device in implementing those functions, such as a chip system. This device can be installed in the network device or used in conjunction with the network device.

[0115] The network architecture and service scenarios described in this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in this application. Those skilled in the art will understand that, with the evolution of communication network architectures and the emergence of new service scenarios, the technical solutions provided in this application are also applicable to similar technical problems. For example, this application can be applied to V2X scenarios.

[0116] based on Figure 1 The communication system shown in this application also provides an application scenario, which can be found in [reference 1]. Figure 2 .

[0117] Figure 2This is a schematic diagram illustrating an application scenario of an embodiment of this application. For example... Figure 2 As shown, the network device configures a monitoring occasion (MO) for the terminal device in each first time period, or the network device configures multiple MOs for the terminal device in multiple first time periods (one first time period includes one MO (described as an example), and one first time period may also include multiple MOs, which is not limited). Each MO represents whether the terminal device is monitoring for a wake-up signal (WUS) on the corresponding time-frequency resource. The first time period can refer to one or more: frame, subframe, slot, symbol, mini-slot, etc., or the first time period can also be a period of time predefined or pre-configured by the protocol, which is not limited.

[0118] In some embodiments, WUS can be replaced by a low-power wake-up signal (LP-WUS) (or other terms, which are not limited thereto), and MO can be replaced by LP-WUS MO. For ease of description, LP-WUS MO and LP-WUS will be used as examples in the following description.

[0119] In the embodiments of the present application, the LP-WUS can also be one or more of an on-off keying (OOK) signal (such as OOK-1, OOK-2, OOK-3, OOK-4, etc.), a sequence signal (such as a Gold sequence signal, an M sequence signal, a ZC sequence signal, a Chirp sequence signal, a Walsh sequence signal, a Golay sequence signal, a Kasami sequence signal, a low density sequence signal, a discrete Fourier transform (DFT) / fast Fourier transform (FFT) sequence signal, a symbol-based sequence signal based on quadrature amplitude modulation (QAM), etc.), an amplitude shift keying (ASK) signal, a frequency shift keying (FSK) signal, an orthogonal frequency division multiplexing (OFDM) signal, a chirp signal, etc., or the LP-WUS can also be a signal obtained by optimizing the above signals, etc., and the like, and no limitation is made thereto. Similarly, the above description also applies to the low-power consumption signal or low-power consumption information, etc., appearing hereinafter, and the like, and no further description is made hereinafter.

[0120] The communication method of the embodiments of the present application is described below in conjunction with the accompanying drawings.

[0121] For the convenience of understanding and description, the communication method of the embodiments of the present application is described below by taking a network side device and a terminal side device, for example, a network equipment and a terminal equipment, as an example, but this should not constitute any limitation on the execution subject of the communication method of the embodiments of the present application. For example, the network side device can be a network equipment, or a functional module (such as a circuit, a chip or a chip system, etc.), or a logic node, a logic module or software capable of realizing all or part of the functions of the network side device. Similarly, the terminal side device can be a terminal equipment, or a functional module (such as a circuit, a chip or a chip system, etc.), or a logic node, a logic module or software capable of realizing all or part of the functions of the terminal side device.

[0122] When the steps of sending or receiving are performed by a module (such as a circuit, a chip or a chip system, etc.), a logic node, a logic module or software, etc., in the network side device and the terminal side device, the sending / receiving can be understood as communication through a communication interface, an input / output interface, a pin or a circuit, etc.

[0123] In the embodiments of the present application, the terminal device comprises a first module and a second module. The first module and the second module are only named for distinction, and the specific naming does not limit the protection scope of the present application. For example, the second module can be a second circuit or a wake-up circuit or a low-power-consumption circuit or a low-power-consumption module, and the first module can be a first circuit or a main circuit or a high-power-consumption circuit or a high-power-consumption module. For the convenience of description, the following is uniformly described as the first module and the second module.

[0124] The second module has the following functions: maintaining the connection with the network device, transmitting small packet data or measurement results, turning on or off the first module, and the like. The first module can have the following functions: for data transmission with the network device, and the like.

[0125] Figure 3 FIG. 1 is a schematic diagram of an interaction flow of a communication method according to an embodiment of the present application. As shown in FIG. 1, the method comprises the following steps. Figure 3

[0126] S301, the network device sends first information to the terminal device. Correspondingly, the terminal device receives the first information.

[0127] For example, the network device sends the first information to the first module of the terminal device, and the first module of the terminal device receives the first information.

[0128] For example, the network device sends the first information to the second module of the terminal device, and the second module of the terminal device receives the first information.

[0129] In some embodiments, the first information is carried in a low-power-consumption signal or low-power-consumption information. The description of the low-power-consumption signal or low-power-consumption information can be referred to the foregoing description of the LP-WUS, and will not be repeated here.

[0130] Optionally, the first information can also be carried in a non-low-power-consumption signal or non-low-power-consumption information.

[0131] For example, the first information can be physical layer signaling, such as downlink control information (DCI).

[0132] For example, the first information can be high-layer signaling, such as media access control-control element (MAC CE) or radio resource control (RRC) signaling, and the like.

[0133] ​The first information can indicate related information of the M LP-WUS MOs. The related information of the M LP-WUS MOs includes information of positions of the M LP-WUS MOs, and can also include information of an LP-WUS MO configuration to which the M LP-WUS MOs belong. M is a positive integer greater than or equal to 1.

[0134] In some embodiments, the related information of the M LP-WUS MOs indicated by the first information includes:

[0135] a first LP-WUS MO configuration, and the LP-WUS MOs configured by the first LP-WUS MO configuration include the M LP-WUS MOs;

[0136] and / or,

[0137] positions of the M LP-WUS MOs.

[0138] When the first information indicates the first LP-WUS MO configuration, the first information can be DCI or MAC-CE. When the first information indicates the positions of the M LP-WUS MOs, the first information can be DCI.

[0139] When the first information indicates the first LP-WUS MO configuration, the terminal device determines the M LP-WUS MOs according to the first LP-WUS MO configuration, which can reduce signaling overhead.

[0140] When the first information indicates the positions of the M LP-WUS MOs, the terminal device can directly determine the positions of the M LP-WUS MOs without determining corresponding LP-WUS MOs according to the LP-WUS MO configuration, so this can reduce processing power consumption of the terminal device in determining the positions of the M LP-WUS MOs.

[0141] In the embodiments of the present application, the LP-WUS MO configuration can be used to configure multiple LP-WUS MOs.

[0142] Optionally, the LP-WUS MO configuration can also be used to indicate the number of LP-WUS MOs that do not need to monitor LP-WUS. In this way, the terminal device can determine the positions of the LP-WUS MOs that need to monitor LP-WUS by itself, which can support the terminal device to flexibly determine the positions of the LP-WUS MOs that do not need to monitor LP-WUS.

[0143] Optionally, the LP-WUS MO configuration can also be used to indicate the number of LP-WUS MOs that need to be monitored for LP-WUS. In this way, the terminal device can determine the positions of the LP-WUS MOs that need to be monitored by itself, which can support the terminal device to flexibly determine the positions of the LP-WUS MOs that need to be monitored.

[0144] The description of the LP-WUS MO configuration can refer to Table 1. The content described in Table 1 is only as an example, not as the final limit.

[0145] Table 1

[0146] LP-WUS MO configuration Explanation LP-WUS MO configuration 1 Slot 1, Slot 3, Slot 5, Slot 7 LP-WUS MO configuration 2 Slot 2, Slot 4, Slot 6, Slot 8

[0147] As shown in Table 1, a first time period is a slot, and a slot includes an LP-WUS MO:

[0148] For the LP-WUS MO configuration 1, it means to configure the LP-WUS MO in the slot 1, the slot 3, the slot 5 and the slot 7;

[0149] For the LP-WUS MO configuration 2, it means to configure the LP-WUS MO in the slot 2, the slot 4, the slot 6 and the slot 8.

[0150] Table 1 takes the slot as an example, and the slot can be replaced by a symbol or a mini-slot or a subframe or a frame number, etc., which is not limited. Similarly, the above content is also applicable to the following, which will not be repeated here.

[0151] The above is an example of configuring one LP-WUS MO in one slot. In some embodiments, one LP-WUS MO can be configured in each slot, and the LP-WUS MO configuration can be used to determine or select or exclude part of the LP-WUS MOs configured in the slots. For example, one LP-WUS MO can be configured in each of the 100 slots, i.e., there are 100 LP-WUS MOs, and the LP-WUS MO configuration can be used to determine or select or exclude part of the LP-WUS MOs in the 100 slots, for example, the LP-WUS MO configuration 3 is used to determine or select or exclude the LP-WUS MOs configured in the even slots in the 100 slots, i.e., the LP-WUS MO configuration 3 is used to configure 50 LP-WUS MOs, each of which corresponds to an even slot. Similarly, the embodiments of the present application also support configuring one or more LP-WUS MOs in a frame or a subframe or a symbol or a mini-slot, etc. For ease of description, the following describes an example of configuring LP-WUS MO in a slot.

[0152] In the embodiments of the present application, the LP-WUS MOs configured by the LP-WUS MO configuration can be discrete or continuous.

[0153] Taking the LP-WUS MOs configured by the LP-WUS MO configuration as discrete as an example:

[0154] For example, the LP-WUS MO configuration 4 is used to configure one LP-WUS MO in slot 1, one LP-WUS MO in slot 5, and one LP-WUS MO in slot 8, or in other words, the terminal device monitors the LP-WUS in the LP-WUS MOs in slot 1, slot 5, and slot 8, or the terminal device does not monitor the LP-WUS in the LP-WUS MOs in slot 1, slot 5, and slot 8.

[0155] For example, the LP-WUS MO configuration 5 is used to configure the LP-WUS MO on the slots 6 to 10 (each of the slots 1 to 5 can also be configured with the LP-WUS MO, but the LP-WUS MO configured on each of the slots 1 to 5 is irrelevant to the LP-WUS MO configuration 1), or in other words, the terminal device monitors the LP-WUS on the LP-WUS MO on the slots 6 to 10, does not monitor the LP-WUS on the LP-WUS MO on the slots 1 to 5, or in other words, the terminal device does not monitor the LP-WUS on the LP-WUS MO on the slots 6 to 10, but monitors the LP-WUS on the LP-WUS MO on the slots 1 to 5.

[0156] For example, the LP-WUS MO configuration 6 is used to configure the LP-WUS on the odd slots (the even slots can also be configured with the LP-WUS MO, but the LP-WUS MO configured on the even slots is irrelevant to the LP-WUS MO configuration 1), or in other words, the terminal device monitors the LP-WUS on the LP-WUS MO on the odd slots, does not monitor the LP-WUS on the LP-WUS MO on the even slots, or in other words, the terminal device does not monitor the LP-WUS on the LP-WUS MO on the odd slots, but monitors the LP-WUS on the LP-WUS MO on the even slots.

[0157] WUS of the terminal device; or in other words, the terminal device monitors the LP-WUS on the LP-WUS MO on the odd slots, does not monitor the LP-WUS on the LP-WUS MO on the even slots.

[0158] For example, the LP-WUS MO configuration 7 is used to configure the LP-WUS on the even slots (the odd slots can also be configured with the LP-WUS MO, but the LP-WUS MO configured on the odd slots is irrelevant to the LP-WUS MO configuration 1), or in other words, the terminal device monitors the LP-WUS on the LP-WUS MO on the even slots, does not monitor the LP-WUS on the LP-WUS MO on the odd slots, or in other words, the terminal device does not monitor the LP-WUS on the LP-WUS MO on the even slots, but monitors the LP-WUS on the LP-WUS MO on the odd slots.

[0159] WUS of the terminal device; or in other words, the terminal device monitors the LP-WUS on the LP-WUS MO on the odd slots, does not monitor the LP-WUS on the LP-WUS MO on the even slots.

[0160] For example, the slot where the LP-WUS MO configured by the LP-WUS MO configuration 8 locates satisfies the following formula: 3*T+2, T is a positive integer greater than or equal to 1, T represents the order of the LP-WUS MO configured by the LP-WUS MO configuration. For example, T=1, the first LP-WUS MO configured by the LP-WUS MO configuration 8 locates at the slot 5, T=2, the second LP-WUS MO configured by the LP-WUS MO configuration 8 locates at the slot 8, T=3, the second LP-WUS MO configured by the LP-WUS MO configuration 8 locates at the slot 11.

[0161] For example, the slot where the LP-WUS MO configured by the LP-WUS MO configuration 8 locates satisfies the following formula: 3*T+2, T is a positive integer greater than or equal to 1, T represents the order of the LP-WUS MO configured by the LP-WUS MO configuration. For example, T=1, the first LP-WUS MO configured by the LP-WUS MO configuration 8 locates at the slot 5, T=2, the second LP-WUS MO configured by the LP-WUS MO configuration 8 locates at the slot 8, T=3, the second LP-WUS MO configured by the LP-WUS MO configuration 8 locates at the slot 11.

[0162] For example, the LP-WUS MO configuration 9 is used to configure the position of the first LP-WUS MO and the duration, the duration can be an absolute time, such as 10ms, 1ms, 0.25ms, 0.1ms, etc., or a slot number or a slot quantity, or a mini-slot number or a mini-slot quantity, or a symbol number or a symbol quantity, or a preconfigured time number, for example, the duration is a slot quantity, for example, the LP-WUS MO configuration 9 is used to configure the position of the first LP-WUS MO as the third slot and the duration as 5 slots, then the LP-WUS MO configured by the LP-WUS MO configuration 9 locates at:

[0163] The third slot, the fourth slot, the fifth slot, the sixth slot and the seventh slot.

[0164] For example, the LP-WUS MO configuration 10 is used to configure the position of the first LP-WUS MO and the quantity of the LP-WUS MO, for example, the LP-WUS MO configuration 10 is used to configure the position of the first LP-WUS MO as the third slot and the quantity of the LP-WUS MO as 5, then the LP-WUS MO configured by the LP-WUS MO configuration 10 locates at: the third slot, the fourth slot, the fifth slot, the sixth slot and the seventh slot.

[0165] For example, the LP-WUS MO configuration 11 is used to configure the position of the first LP-WUS MO and the position duration of the last LP-WUS MO. For example, the LP-WUS MO configuration 11 is used to configure the position of the first LP-WUS MO as the third time slot and the position of the last LP-WUS MO as the seventh time slot, then the LP-WUS MOs configured by the LP-WUS MO configuration 11 are located in the third time slot, the fourth time slot, the fifth time slot, the sixth time slot and the seventh time slot respectively.

[0166] For example, the LP-WUS MO configuration 12 is used to configure the position of the first LP-WUS MO and the end time. The end time can be an absolute time, such as 10 ms, 1 ms, 0.25 ms, 0.1 ms, etc., can also be a time slot number or a time slot quantity, can also be a mini time slot number or a mini time slot quantity, can also be a symbol number or a symbol quantity, or can be a preconfigured time number. Taking the time slot quantity as an example, the LP-WUS MO configuration 12 is used to configure the position of the first LP-WUS MO as the third time slot and the end time as the seventh time slot, then the LP-WUS MOs configured by the LP-WUS MO configuration 12 are located in the third time slot, the fourth time slot, the fifth time slot, the sixth time slot and the seventh time slot respectively.

[0167]

[0168] The description of the LP-WUS MOs configured by the LP-WUS MO configuration as discrete can also be seen from Table 2. The contents shown in Table 2 are only examples and are not final.

[0169] Table 2

[0170] Configuration number Indication meaning Configuration 1 LP-WUS MO skipping 5 slots Configuration 2 Every 3 slots, skip the 2nd slot Configuration 3 Every 3 slots, skip the first 2 slots

[0171] As shown in Table 2:

[0172] The LP-WUS MO configuration corresponding to configuration 1 is used to configure the LP-WUS MOs that skip 5 time slots.

[0173] The LP-WUS MO configuration corresponding to configuration 2 is used to configure every three time slots, then the LP-WUS MOs on the middle time slots are not monitored, for example, the time slots of the LP-WUS MOs configured by the LP-WUS MO configuration 1 are: time slot 1, time slot 3, time slot 5, time slot 7, etc. The LP-WUS MOs on the time slots 2, 4 and 6 are the LP-WUS MOs that need to be skipped for monitoring.

[0174] ​ The LP-WUS MO configuration corresponding to configuration 3 is configured for every three slots, and the LP-WUS MOs on the first two slots are not monitored, for example, the slots where the LP-WUS MOs configured by the LP-WUS MO configuration 1 are located are: slot 1, slot 4, slot 7, and the like.

[0175] Among them, the LP-WUS MOs on slots 2, 3, 5, and 6 are LP-WUS MOs that need to be skipped for monitoring.

[0176] Based on Table 2, when the first information can indicate the above configuration, the terminal device determines, according to the configuration, that the LP-WUS MOs of the LP-WUS do not need to be monitored.

[0177] One possible implementation, the LP-WUS MO configuration is related to the subcarrier spacing. See Table 3. Among them, the content described in Table 3 is only as an example, not as the final limit.

[0178] Table 3

[0179]

[0180] As shown in Table 3:

[0181] For subcarrier spacing 15 = 15*2 0 KHz, configuration 1 indicates that the number of slots between adjacent LP-WUS MOs configured by the LP-WUS MO configuration 1 satisfies: 0+1;

[0182] For subcarrier spacing 30 = 15*2 1 KHz, configuration 1 indicates that the number of slots between adjacent LP-WUS MOs configured by the LP-WUS MO configuration 1 satisfies: 1+1;

[0183] For subcarrier spacing 60 = 15*2 2 KHz, configuration 1 indicates that the number of slots between adjacent LP-WUS MOs configured by the LP-WUS MO configuration 1 satisfies: 2+1.

[0184] For subcarrier spacing 15*2 n KHz, configuration 1 indicates that the number of slots between adjacent LP-WUS MOs configured by the LP-WUS MO configuration 1 satisfies: n+1, where n is an integer greater than or equal to 0.

[0185] Optionally, the relationship between the LP-WUS MOs configured by the LP-WUS MO configuration 1 can be different based on different subcarrier spacing.

[0186] Exemplarily,

[0187] For subcarrier spacing of 15KHz, the LP-WUS MO configuration 1 can be used to configure the number of time slots to skip monitoring or the number of consecutive time slots to monitor, which can be: {1, 2, 3, … 20, 30, 40, … 80, 100};

[0188] For subcarrier spacing of 30KHz, the LP-WUS MO configuration 1 can be used to configure the number of time slots to skip monitoring or the number of consecutive time slots to monitor, which can be: {1, 2, 3, …, 40, 60, 80, 100, 120, 160, 200};

[0189] For subcarrier spacing of 60KHz, the LP-WUS MO configuration 1 can be used to configure the number of time slots to skip monitoring or the number of consecutive time slots to monitor, which can be: {1, 2, 3, …, 80, 120, 160, 200, 240, 320, 400};

[0190] For subcarrier spacing of 120KHz, the LP-WUS MO configuration 1 can be used to configure the number of time slots to skip monitoring or the number of consecutive time slots to monitor, which can be: {1, 2, 3, …, 160, 240, 320, 400, 480, 640, 800}.

[0191] The description of the position of the LP-WUS MO can refer to Table 4. The content described in Table 4 is only as an example, not as the final limitation.

[0192] Table 4

[0193] Position of LP-WUS MO Explanation Position 1 Slot 1 Position 2 Slot 3 Position 3 Slot 5

[0194] As shown in Table 4:

[0195] The position of the LP-WUS MO is 1, indicating that the position of the LP-WUS MO is time slot 1;

[0196] The position of the LP-WUS MO is 2, indicating that the position of the LP-WUS MO is time slot 3;

[0197] The position of the LP-WUS MO is 3, indicating that the position of the LP-WUS MO is slot 5.

[0198] Table 4 is described by taking the position of the LP-WUS MO as a slot as an example, but is not limited to the scenario in which the position of the LP-WUS MO is indicated by a symbol / minislot or a subframe or a frame or absolute time or relative time.

[0199] In this way, the network device can indicate the related information of the M LP-WUS MOs to the terminal device through the first information.

[0200] S302, the terminal device monitors the LP-WUS on the N LP-WUS MOs according to the first information, and the N LP-WUS are related to the M LP-WUS.

[0201] When the terminal device receives the first information, the terminal device determines the M LP-WUS MOs according to the related information of the M LP-WUS MOs indicated by the first information, and determines the N LP-WUS MOs according to the M LP-WUS MOs. The N LP-WUS MOs are the LP-WUS MOs on which the terminal device monitors the LP-WUS.

[0202] In some embodiments, the M LP-WUS MOs described above are the LP-WUS MOs on which the terminal device monitors the LP-WUS. Accordingly, the N LP-WUS MOs can be the same as the M LP-WUS MOs.

[0203] For example, when the network device indicates the LP-WUS MO on which the terminal device monitors the LP-WUS to the terminal device, the terminal device monitors the LP-WUS according to the LP-WUS MO indicated by the network device.

[0204] In this way, the terminal device can directly monitor the low-power wake-up signal on the M low-power wake-up signal monitoring occasions.

[0205] In some embodiments, the M LP-WUS MOs described above are the LP-WUS MOs on which the terminal device does not monitor the LP-WUS. Accordingly, the N LP-WUS MOs can be different from the M LP-WUS MOs.

[0206] For example, when the network device indicates the LP-WUS MO on which the terminal device does not monitor the LP-WUS to the terminal device, the terminal device does not monitor the LP-WUS on the LP-WUS MO indicated by the network device. In this way, the terminal device can determine the M LP-WUS MOs on which the LP-WUS does not need to be monitored, and thus the number of times of monitoring the LP-WUS by the terminal device can be reduced.

[0207] In some embodiments, when the N LP-WUS MOs are the same as the M LP-WUS MOs, the first information indicating the first LP-WUS MO configuration can include any of the following:

[0208] The first information indicates to activate the first LP-WUS MO configuration.

[0209] The first information indicates to switch (or can be understood as convert) from the second LP-WUS MO configuration to the first LP-WUS MO configuration, and the second LP-WUS MO configuration is used to configure K LP-WUS MOs, and the K LP-WUS MOs are different from the M LP-

[0210] WUS MO, K is a positive integer greater than or equal to 1.

[0211] The first information indicates to monitor the LP-WUS MO configured by the first LP-WUS MO configuration.

[0212] It should be noted that the K LP-WUS MOs different from the M LP-WUS MOs can be understood as: when K is greater than or equal to M, there is at least one LP-WUS MO in the K LP-WUS MOs, and the at least one LP-WUS MO does not belong to the M LP-WUS MOs; when K is less than M, there is at least one LP-WUS MO in the M LP-WUS MOs, and the at least one LP-WUS MO does not belong to the K LP-WUS MOs.

[0213] In this way, the terminal device can determine the LP-WUS MO of the LP-WUS to be monitored according to any of the above.

[0214] The following will be described from different scenarios.

[0215] Scenario 1: Taking activating the first LP-WUS MO configuration as an example.

[0216] When the first information indicates to activate the first LP-WUS MO configuration, the network device activates the first LP-WUS MO configuration in multiple ways.

[0217] Mode a1:

[0218] When there is one LP-WUS MO configuration, i.e., only the first LP-WUS MO configuration, the first information includes one bit, which is 1, indicating that the first LP-WUS MO configuration is activated, and which is 0, indicating that the first LP-WUS MO configuration is not activated; or which is 1, indicating that the first LP-WUS MO configuration is not activated, and which is 0, indicating that the first LP-WUS MO configuration is activated.

[0219] Mode a2:

[0220] When there are at least two LP-WUS MO configurations, the at least two LP-WUS MO configurations include the first LP-WUS MO configuration, and the first information includes identification information of the first LP-WUS MO (for example, the network device can set an identification or an index, etc. for each LP-WUS MO configuration), and the terminal device determines to activate the first LP-WUS MO configuration according to the identification information of the first LP-WUS MO configuration carried in the first information.

[0221] The description of mode a2 can also refer to Table 5. The content shown in Table 5 is only as an example, not as the final limit.

[0222] Table 5

[0223] Bit value Explanation 00 Activate the first LP-WUS MO configuration 01 Activate the second LP-WUS MO configuration 10 Activate the third LP-WUS MO configuration 11 Activate the fourth LP-WUS MO configuration

[0224] As shown in Table 5, the first information includes two bits:

[0225] The two bits are 00, indicating that the first LP-WUS MO configuration is activated.

[0226] The two bits are 01, indicating that the second LP-WUS MO configuration is activated.

[0227] The two bits are 10, indicating that the third LP-WUS MO configuration is activated.

[0228] The two bits are 11, indicating that the fourth LP-WUS MO configuration is activated.

[0229] In this way, the terminal device can determine the LP-WUS MO configuration to be activated according to different values of the two bits in the first information.

[0230] Mode a3:

[0231] When there are at least two LP-WUS MO configurations, the at least two LP-WUS MO configurations include a first LP-WUS MO configuration, the first information includes a bit map, at least part of the bit positions in the bit map correspond to the LP-WUS MO configurations, and the value of the bit position can represent whether to activate or not to activate the corresponding LP-WUS MO configuration, and the terminal device determines whether to activate the first LP-WUS MO configuration according to the bit map carried in the first information.

[0232] For example, there are five LP-WUS MO configurations, which correspond to a bit map {01000}, the second bit position in the bit map corresponds to the first LP-WUS MO configuration, the bit value in the second bit position in the bit map is 1, which indicates that the first LP-WSU MO configuration is activated, and the bit values in the remaining bit positions in the bit map are all 0, which indicates that the corresponding LP-WUS MO configuration is not activated.

[0233] It should be uniformly pointed out that the at least two LP-WUS MO configurations described above can be pre-configured in the terminal device or the network device, or can be indicated by the network device to the terminal device, and no limitation is made in this regard.

[0234] Scenario 2: Take the indication of switching from the second LP-WUS MO to the first LP-WUS MO configuration as an example.

[0235] When the first information indicates switching from the second LP-WUS MO configuration to the first LP-WUS MO configuration, the network device can indicate switching from the second LP-WUS MO configuration to the first LP-WUS MO configuration in various ways.

[0236] Method b1:

[0237] When there are a first LP-WUS MO configuration and a second LP-WUS MO configuration, the first information includes identification information of the first LP-WUS MO (for example, the network device can set an identification or an index for each LP-WUS MO configuration, etc.), and the terminal device determines to switch the LP-WUS MO configuration according to the identification information of the LP-WUS MO configuration carried in the first information.

[0238] Method b2:

[0239] When there are a first LP-WUS MO configuration and a second LP-WUS MO configuration, the first information includes a bit, when the bit value is 1, it indicates switching, and when the bit value is 0, it indicates not switching; or, when the bit value is 1, it indicates not switching, and when the bit value is 0, it indicates switching.

[0240] Mode b3:

[0241] When there are more than three LP-WUS MO configurations, the first information includes multiple bits, and different values of the multiple bits represent different meanings. Please refer to Table 6. The content shown in Table 6 is only as an example, not as the final limit.

[0242] Table 6

[0243]

[0244]

[0245] As shown in Table 6, the first information includes three bits:

[0246] When the value of the three bits is 000, it means no switching;

[0247] When the value of the three bits is 001, it means switching from the first LP-WUS MO configuration to the second LP-WUS MO configuration;

[0248] When the value of the three bits is 010, it means switching from the first LP-WUS MO configuration to the third LP-WUS MO configuration;

[0249] When the value of the three bits is 011, it means switching from the second LP-WUS MO configuration to the first LP-WUS MO configuration;

[0250] When the value of the three bits is 100, it means switching from the second LP-WUS MO configuration to the third LP-WUS MO configuration;

[0251] When the value of the three bits is 101, it means switching from the third LP-WUS MO configuration to the first LP-WUS MO configuration;

[0252] When the value of the three bits is 110, it means switching from the third LP-WUS MO configuration to the second LP-WUS MO configuration.

[0253] In this way, the terminal device can determine the corresponding switching mode according to the different values of the three bits in the first information.

[0254] Scenario 3: Take monitoring the LP-WUS MO configured by the first LP-WUS MO configuration as an example.

[0255] When the first information indicates monitoring the LP-WUS MO configured by the first LP-WUS MO configuration, the network device can implement the indication of monitoring the LP-WUS MO configured by the first LP-WUS MO configuration in various ways.

[0256] Mode c1:

[0257] When there is one LP-WUS MO configuration, i.e., only the first LP-WUS MO configuration, the first information includes one bit, which is 1 when it indicates monitoring the LP-WUS MO configured by the first LP-WUS MO configuration, and which is 0 when it indicates not monitoring the LP-WUS MO configured by the first LP-WUS MO configuration; or, which is 1 when it indicates not monitoring the LP-WUS MO configured by the first LP-WUS MO configuration, and which is 0 when it indicates monitoring the LP-WUS MO configured by the first LP-WUS MO configuration.

[0258] When there are at least two LP-WUS MO configurations, the network device can implement the indication of monitoring the first LP-WUS MO configuration by mode a2, which will not be repeated.

[0259] In some embodiments, when the N LP-WUS MOs are different from the M LP-WUS MOs, the first information indicating the first LP-WUS MO configuration can include any of the following:

[0260] The first information indicates deactivating the first LP-WUS MO configuration;

[0261] The first information indicates releasing the first LP-WUS MO configuration;

[0262] The first information indicates not monitoring the LP-WUS MO configured by the first LP-WUS MO configuration.

[0263] When the first information indicates deactivating, releasing, or not monitoring the first LP-WUS MO configuration, the network device can implement the indication of deactivating, releasing, or not monitoring the first LP-WUS MO configuration by the aforementioned modes, which can be referred to the aforementioned description of the first information indicating activating, switching, or monitoring the first LP-WUS MO configuration, which will not be repeated.

[0264] In this way, the terminal device determines the LP-WUS MO of the LP-WUS that does not need to be monitored according to any of the above.

[0265] In the scheme, the terminal device can determine the M LP-WUS MOs according to the first information, determine the N LP-WUS MOs according to the M LP-WUS MOs, and monitor the LP-WUS for indicating whether to perform the PDCCH blind detection on the N LP-WUS MOs. In this way, the terminal device only monitors the LP-WUS on the specific LP-WUS MOs, which can effectively reduce the number of times of monitoring the LP-WUS by the terminal device, thereby reducing the overall power consumption of the terminal device when monitoring the LP-WUS.

[0266] In some embodiments, the method can further include:

[0267] S301a, the network device sends second information to the terminal device. Correspondingly, the terminal device receives the second information.

[0268] For example, the network device sends the second information to the first module of the terminal device, and the first module of the terminal device receives the second information.

[0269] For another example, the network device sends the second information to the second module of the terminal device, and the second module of the terminal device receives the second information.

[0270] The second information is used to configure one or more LP-WUS MO configurations. The first LP-WUS MO configuration is one of the one or more LP-WUS MO configurations.

[0271] In one possible example, the second information can be high-layer signaling, such as RRC information, etc.

[0272] When the network device indicates multiple LP-WUS MO configurations to the terminal device, the network device can set a corresponding identifier or index for each LP-WUS MO configuration in the multiple LP-WUS MO configurations. In this way, the network device can indicate to the terminal device through the first information to activate or release or switch or monitor or skip or not monitor or deactivate the first LP-WUS MO configuration.

[0273] When the one or more LP-WUS MO configurations are indicated by the network device to the terminal device, the execution order of S301a is before S301.

[0274] In this way, the terminal device can select the first LP-WUS MO configuration from the one or more LP-WUS MO configurations configured by the network device according to the first information, which can support the terminal device to monitor the low-power wake-up signal on part of the LP-WUS MOs, thereby supporting to reduce the overall power consumption of the terminal device when monitoring the LP-WUS.

[0275] Figure 3The terminal device determines the LP-WUS MO for monitoring the LP-WUS according to the indication of the network device, but the scenario in which the terminal device determines the LP-WUS MO for monitoring the LP-WUS by itself is not limited. For details, refer to Figure 4 .

[0276] Figure 4 The interaction flowchart of another communication method of an embodiment of the present application is described. As shown in Figure 4 , the method includes the following steps.

[0277] Optionally, in S401, the terminal device determines a first event. The first event can be used by the terminal device to determine to activate or release or monitor or switch or deactivate a certain LP-WUS MO configuration.

[0278] In one possible implementation, the first event includes at least one of the following:

[0279] a sending state of uplink information;

[0280] a state of a timer related to monitoring the LP-WUS;

[0281] a state of the terminal device.

[0282] For example, the sending state of the uplink information, the state of the timer related to monitoring the LP-WUS, and the state of the terminal device described above can be related to the LP-WUS MO for monitoring the LP-WUS determined by the terminal device.

[0283] For example, when it is determined that the terminal device sends the uplink information described above to the network device, the terminal device determines that there is a need to receive the PDCCH, and further determines that the monitoring of the LP-WUS needs to be performed. Accordingly, the terminal device monitors the LP-WUS in the LP-WUS MO of multiple slots, and the number of slots corresponding to the multiple slots is greater than a threshold.

[0284] For example, when it is determined that the terminal device does not send the uplink information described above to the network device, the terminal device determines that there is no need to receive the PDCCH, and further determines that the monitoring of the LP-WUS does not need to be performed. Accordingly, the terminal device monitors the LP-WUS in the LP-WUS MO of part of the slots, and the number of slots corresponding to the part of the slots (which can be 0) is less than the threshold.

[0285] For example, when the terminal device determines that there is a requirement for receiving the PDCCH, the terminal device monitors the LP-WUS in the LP-WUS MO of the multiple slots, and then the terminal device ends the monitoring of the LP-WUS in the LP-WUS MO of the multiple slots.

[0286] For example, when the terminal device determines that there is a requirement for receiving the PDCCH, the terminal device monitors the LP-WUS in the LP-WUS MO of the multiple slots, and then the terminal device ends the monitoring of the LP-WUS in the LP-WUS MO of the multiple slots.

[0287] For example, when the terminal device determines that there is a requirement for receiving the PDCCH, the terminal device monitors the LP-WUS in the LP-WUS MO of the multiple slots, and then the terminal device ends the monitoring of the LP-WUS in the LP-WUS MO of the multiple slots.

[0288] In some embodiments, the uplink information includes at least one of the following:

[0289] a scheduling report (SR);

[0290] a buffer state report (BSR);

[0291] a message 1 (Msg1);

[0292] a message 3 (Msg3);

[0293] a message A (MsgA);

[0294] terminal device activation information;

[0295] information for indicating the first LP-WUS configuration.

[0296] In this way, the terminal device can indicate to the network device that the terminal device has a need to receive PDCCH through the indication of any one of the above information. In addition, the terminal device can determine the first LP-WUS MO configuration according to the sending state of the above information.

[0297] Optionally, when the terminal device sends one or more of the above information to the network device, the terminal device can set a corresponding timer, which can be started when the terminal device sends one or more of the above information. The starting time of the timer is the time when the terminal device monitors the LP-WUS in the LP-WUS MO of the plurality of slots. The ending time of the timer is the time when the terminal device stops monitoring the LP-WUS in the LP-WUS MO of the plurality of slots.

[0298] Optionally, when the terminal device sends one or more of the above information to the network device, the terminal device can monitor the LP-WUS in the LP-WUS MO of the plurality of slots, and can stop monitoring the LP-WUS in the LP-WUS MO of the plurality of slots after a period of time.

[0299] In some embodiments, the state of the timer related to monitoring the LP-WUS includes any one of the following:

[0300] Normal, invalid, expired, or timeout.

[0301] For example, when the timer is in a normal state (which can be understood as the timer is running), it indicates that the terminal device has a need to receive PDCCH, and thus it can be determined that the LP-WUS needs to be monitored.

[0302] For another example, when the timer is in an invalid state (which can be understood as the timer is in an ending running state, or stops running, or a certain event triggers the timer to end running in advance, etc.), it indicates that the terminal device does not have a need to receive PDCCH, and thus it can be determined that the LP-WUS does not need to be monitored.

[0303] For another example, when the timer is in an expired state (which can also be understood as the timer is in an ending running state, or stops running, or a certain event triggers the timer to end running in advance, etc.), it indicates that the terminal device does not have a need to receive PDCCH, and thus it can be determined that the LP-WUS does not need to be monitored.

[0304] For another example, when the timer is in a timeout state, it indicates that the terminal device does not have a need to receive PDCCH, and thus it can be determined that the LP-WUS does not need to be monitored.

[0305] Optionally, the state of the timer related to monitoring the LP-WUS can be related to the state of the sending of the uplink information. For example, the terminal device starts the timer related to monitoring the LP-WUS when the terminal device sends the uplink information to the network device. For another example, the terminal device stops the timer related to monitoring the LP-WUS MO when the terminal device does not send the uplink information to the network device.

[0306] In this way, the terminal device can determine the first LP-WUS MO configuration according to the state of the timer.

[0307] In some embodiments, the state of the terminal device comprises any one of the following:

[0308] the contention resolution is completed;

[0309] the contention resolution is not completed;

[0310] the random access response is successfully received;

[0311] the random access response is not successfully received;

[0312] uplink scheduling is not needed;

[0313] uplink scheduling is needed;

[0314] LP-WUS monitoring is not needed;

[0315] LP-WUS monitoring is needed.

[0316] For example, when the state of the terminal device comprises that the contention resolution is completed, the terminal device determines that there is no need to receive the PDCCH, and further can determine that LP-WUS monitoring is not needed.

[0317] For example, when the state of the terminal device comprises that the contention resolution is not completed, the terminal device determines that there is a need to receive the PDCCH, and further can determine that LP-WUS monitoring is needed.

[0318] For example, when the state of the terminal device comprises that the random access response is successfully received, the terminal device determines that there is no need to receive the PDCCH, and further can determine that LP-WUS monitoring is not needed.

[0319] For example, when the state of the terminal device comprises that the random access response is not successfully received, the terminal device determines that there is a need to receive the PDCCH, and further can determine that LP-WUS monitoring is needed.

[0320] For example, when the state of the terminal device includes no uplink scheduling is needed, the terminal device determines that there is no need to receive PDCCH, and further can determine that there is no need to monitor LP-WUS.

[0321] For example, when the state of the terminal device includes uplink scheduling is needed, the terminal device determines that there is a need to receive PDCCH, and further can determine that there is a need to monitor LP-WUS.

[0322] For example, when the state of the terminal device includes no LP-WUS detection is needed, the terminal device determines that there is no need to receive PDCCH, and further can determine that there is no need to monitor LP-WUS.

[0323] For example, when the state of the terminal device includes LP-WUS detection is needed, the terminal device determines that there is a need to receive PDCCH, and further can determine that there is a need to monitor LP-WUS.

[0324] In this way, the terminal device can determine the first LP-WUS MO configuration according to the state of the terminal device described above.

[0325] S402, the terminal device determines a first LP-WUS MO configuration according to a first event, the first LP-WUS MO configuration being used for configuring M LP-WUS MOs.

[0326] The specific description can be referred to the description of the first event described above, and will not be repeated here.

[0327] S403, the terminal device monitors LP-WUS on N LP-WUS MOs, the N LP-WUS MOs being related to the M LP-WUS MOs, and M and N are both positive integers.

[0328] The description of S403 can be referred to the description of S303 described above, and will not be repeated here.

[0329] In one possible implementation, the N LP-WUS MOs are the same as the M LP-WUS MOs, and determining the first LP-WUS MO configuration includes any one of the following:

[0330] activating the first LP-WUS MO configuration;

[0331] switching from a second LP-WUS MO configuration to the first LP-WUS MO configuration;

[0332] monitoring the LP-WUS MO configured by the first LP-WUS MO configuration; or

[0333] The monitoring of the LP-WUS MOs configured by the first LP-WUS MO configuration is not skipped.

[0334] When the N LP-WUS MOs are equal to the M LP-WUS MOs, the M LP-WUS MOs configured by the first LP-WUS MO configuration are the LP-WUS MOs for the terminal device to monitor the LP-WUS. In this way, the number of the LP-WUS MOs for the terminal device to monitor the LP-WUS can be reduced.

[0335] In this way, the terminal device can determine the LP-WUS MOs requiring the LP-WUS according to any one of the above.

[0336] Hereinafter, the first LP-WUS MO configuration is taken as an example for description, but the content is also applicable to other scenarios.

[0337] In some embodiments, the first event includes: from (preparing, or starting, or just ending) sending the SR / BSR / msg1 / msg3 / UE activation information, the terminal device activates the first LP-WUS MO configuration, and after a period of time, the terminal device deactivates the first LP-WUS MO configuration.

[0338] Optionally, the terminal device can also be triggered by other events to deactivate the first LP-WUS MO configuration. For example, the terminal device determines that the contention resolution is completed, successfully receives the random access response, and the like.

[0339] In some embodiments, the first event includes: from (preparing, or starting, or just ending) sending the SR / BSR / msg1 / msg3 / UE activation information, the terminal device activates the first LP-WUS MO configuration after the first time offset, and after a period of time, the terminal device deactivates the first LP-WUS MO configuration.

[0340] Optionally, the terminal device can also be triggered by other events to deactivate the first LP-WUS MO configuration. For example, the terminal device determines that the contention resolution is completed, successfully receives the random access response, and the like.

[0341] It should be noted that the period of time described above can be determined by the terminal device, or can be configured or indicated by the network device, and no limitation is made in this regard. In addition, the first time offset is associated with the capability of the terminal device (or the auxiliary information sent by the UE).

[0342] In some embodiments, the first event comprises: a timer starts from (preparing, or starting, or just ending) the SR / BSR / msg1 / msg3, the starting time of the timer is the time when the terminal device activates the first LP-WUS MO configuration, and the ending time of the timer is the time when the terminal device deactivates the first LP-WUS MO configuration.

[0343] Optionally, the terminal device can also deactivate the first LP-WUS MO configuration triggered by other events. For example, the terminal device determines that the contention resolution is completed, successfully receives a random access response, and the like.

[0344] In some embodiments, the first event comprises: a timer starts from (preparing, or starting, or just ending) the SR / BSR / msg1 / msg3, and the ending time of the timer is the time when the terminal device activates the first LP-WUS MO configuration.

[0345] Optionally, the terminal device can also deactivate the first LP-WUS MO configuration triggered by other events. For example, the terminal device determines that the contention resolution is completed, successfully receives a random access response, and the like.

[0346] In some embodiments, the N LP-WUS MOs are different from the M LP-WUS MOs, and the first LP-WUS MO configuration is determined according to any one of the following:

[0347] deactivating the first LP-WUS MO configuration;

[0348] releasing the first LP-WUS MO configuration;

[0349] not monitoring the LP-WUS MOs configured by the first LP-WUS MO configuration; or

[0350] skipping monitoring the LP-WUS MOs configured by the first LP-WUS MO configuration.

[0351] When the N LP-WUS MOs are different from the M LP-WUS MOs, the M LP-WUS MOs configured by the first LP-WUS MO configuration are the LP-WUS MOs that the terminal device does not need to monitor. In this way, the number of LP-WUS MOs that the terminal device needs to monitor can be reduced.

[0352] In this way, the terminal device can determine the LP-WUS MOs that do not need to be monitored according to any one of the above.

[0353] The following description uses the deactivation of the first LP-WUS MO configuration as an example, but the content is also applicable to other scenarios.

[0354] One possible example is that the first event includes: the terminal device completing contention resolution, and the terminal device deactivating the first LP-WUS MO configuration.

[0355] One possible example is that the first event includes: successfully receiving a random access response and the terminal device deactivating the first LP-WUS MO configuration.

[0356] One possible example is the moment when the terminal device activates the first LP-WUSMO configuration without requiring uplink scheduling.

[0357] One possible example is that the first event includes: the timer associated with monitoring LP-WUS is in an expired or invalid state, and the terminal device deactivates the first LP-WUS MO configuration.

[0358] In the above scheme, the terminal device can determine the first LP-WUS MO configuration based on the first event, and determine the N LP-WUS MOs that need to be monitored for LP-WUS based on the first LP-WUS MO configuration. Thus, the terminal device does not need to directly determine the N LP-WUS MOs based on the network device's instructions, which reduces the signaling interaction overhead between the terminal device and the network device. Furthermore, the terminal device only needs to monitor LP-WUS on a subset of LP-WUS MOs, which effectively reduces the number of times the terminal device monitors LP-WUS, thereby reducing the overall power consumption of the terminal device during LP-WUS monitoring.

[0359] One possible implementation of the above method may also include:

[0360] S401a: The network device sends configuration information to the terminal device. Correspondingly, the terminal device receives this configuration information.

[0361] For example, the network device sends configuration information to the first module of the terminal device, and the first module of the terminal device receives the configuration information.

[0362] For example, the network device sends configuration information to the second module of the terminal device, and the second module of the terminal device receives the configuration information.

[0363] The configuration information is used to configure one or more LP-WUS MO configurations. The first LP-WUS MO configuration is one of the one or more LP-WUS MO configurations.

[0364] When the one or more LP-WUS MO configurations are indicated by a network device to a terminal device, the execution order of S401a is before S401.

[0365] To implement the functions in the methods provided in the present application, the terminal device and the network device can each include hardware structures and / or software modules to implement the above functions in the form of hardware structures, software modules, or hardware structures plus software modules. Whether a certain function in the above functions is implemented in the form of hardware structure, software module, or hardware structure plus software module depends on specific application and design constraints of the technical solutions.

[0366] Figure 5 is a schematic block diagram of a communication apparatus according to an embodiment of the present application. The communication apparatus includes processing circuitry 510 and transceiver circuitry 520, which can be connected or coupled to each other, such as through a bus 530. The communication apparatus can be a first network element or a second network element, etc.
