Description

Communication methods, communication devices and storage media

[0001] This application claims priority to Chinese Patent Application No. CN202510307722.X, filed on March 13, 2025, entitled "Communication Method, Communication Device and Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a communication method, communication device and storage medium. Background Technology

[0003] As terminal specifications further improve, power consumption will become a pressing issue. To further reduce device power consumption, two receiver modules can be introduced: a main receiver (MR) responsible for receiving regular signals, and a low-power wake-up signal (LP-WUS) receiver (LPWUR). The main receiver remains in a dormant state, while the device uses the LPWUR to monitor LP-WUS. If LP-WUS is detected, the MR is woken up.

[0004] With the development of future communication networks, the number of frequency bands and component carriers (CCs) supported by the network and terminal sides is also increasing. Currently, each band or CC can generate a wake-up signal independently. Therefore, terminal devices need multiple independent LP-WUR architectures to receive wake-up signals from multiple bands / CCs, which increases the processing complexity of the terminal devices and introduces additional power consumption. Summary of the Invention

[0005] This application provides a communication method, communication device, and storage medium, which can reduce the processing complexity of terminal equipment and avoid frequency band overload.

[0006] This application provides a communication method, optionally executed by a first device. The first device can be a terminal device, a component or device applied to the terminal device (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the terminal device's functions. In this method, the first device receives first information from a second device. The first information is used to configure M auxiliary receivers on the first device. The M auxiliary receivers include a first auxiliary receiver, which is used to wake up X frequency bands out of N frequency bands of the main receiver (or, in other words, the first auxiliary receiver supports waking up X frequency bands out of N frequency bands of the main receiver). At least one of the X frequency bands is different from the first frequency band, where the first frequency band is the frequency band where the first auxiliary receiver is located. M is a positive integer less than or equal to N, and X is a positive integer. The first device configures the M auxiliary receivers according to the first information, thereby receiving wake-up signals from the M auxiliary receivers and waking up different frequency bands of the main receiver.

[0007] Based on the first aspect of this application, in some possible implementations, the first information includes at least one of M, an index of a first frequency band, and an index of X frequency bands.

[0008] In this embodiment, by clarifying the content of the first information, the first device can configure the first auxiliary receiver according to the first information. Then, when a wake-up signal is received, the first auxiliary receiver can activate one or more of the X frequency bands according to the wake-up signal. Therefore, the number of auxiliary receivers deployed on the terminal device can be reduced, and the power consumption of the terminal device can be reduced.

[0009] A second aspect of this application provides a communication method. Optionally, the execution subject of this method may be a first device, which may be a terminal device, a component or device applied to the terminal device (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the terminal device's functions. In this method, the first device receives first information from a second device. The first information includes at least one of the following: the number M of auxiliary receivers activated by the first device, the index of the frequency band where each auxiliary receiver is located, and the index of the frequency band that each auxiliary receiver supports for waking up the main receiver. The M auxiliary receivers include a first auxiliary receiver, which is used to wake up X frequency bands out of N frequency bands of the main receiver (or, the first auxiliary receiver supports waking up X frequency bands out of N frequency bands of the main receiver). At least one of these X frequency bands is different from the first frequency band, where the first frequency band is the frequency band where the first auxiliary receiver is located. M is a positive integer less than or equal to N, and X is a positive integer. The first device configures M auxiliary receivers according to the first information, and then receives wake-up signals from the M auxiliary receivers to wake up the main receiver at different frequency bands.

[0010] Based on the first and second aspects of this application, since at least one of the M auxiliary receivers (i.e., the first auxiliary receiver) supports waking up X frequency bands out of the N frequency bands of the master receiver, the number of auxiliary receivers deployed on the terminal device can be reduced, thereby reducing the power consumption of the terminal device. Simultaneously, since one auxiliary receiver can wake up X frequency bands of the master receiver, the network device can schedule LP-WUS on at least two frequency bands through one auxiliary receiver on the terminal device, thus solving the frequency band overload problem caused by the terminal device residing on a single frequency band for an extended period.

[0011] Based on the first and second aspects of this application, in some possible implementations, the X frequency bands include the first frequency band.

[0012] Since the first frequency band is the frequency band where the first auxiliary receiver is located, and at least one of the X frequency bands is different from the first frequency band, it can be understood that the first auxiliary receiver supports waking up the first frequency band of the master receiver, as well as at least one frequency band other than the first frequency band, thereby realizing cross-frequency band wake-up of the master receiver.

[0013] Based on the first and second aspects of this application, in some possible implementations, the first device may also receive a first signal from the second device, the first signal being located on a first frequency band, the first signal being used to instruct the first auxiliary receiver to wake up one or more of the X frequency bands of the main receiver.

[0014] In this embodiment, since the first device can receive the first signal on the first frequency band of the receiver to wake up one or more of the X frequency bands of the main receiver, the number of auxiliary receivers deployed on the terminal device can be reduced, thereby reducing the power consumption of the terminal device.

[0015] Based on the first and second aspects of this application, in some possible implementations, the first signal satisfies at least one of the following:

[0016] The type of the first signal corresponds to the first auxiliary receiver;

[0017] The resource information of the first signal corresponds to X frequency bands; or,

[0018] The monitoring period of the first signal corresponds to X frequency bands.

[0019] In this embodiment, since the first signal corresponds to the first auxiliary receiver or the X frequency bands used by the first auxiliary receiver to wake up, the first auxiliary receiver can correctly wake up the frequency band of the main receiver according to the first signal.

[0020] Based on the first and second aspects of this application, in some possible implementations, the M auxiliary receivers further include a second auxiliary receiver, which is used to wake up Y of the N frequency bands of the main receiver, and the Y frequency bands are different from the X frequency bands.

[0021] In this embodiment, since different auxiliary receivers can wake up different frequency bands of the main receiver, the number of auxiliary receivers deployed on the terminal device can be reduced, thereby reducing the power consumption of the terminal device.

[0022] Based on the first and second aspects of this application, in some possible implementations, the first device may also send second information to the second device, the second information being used to indicate the capabilities supported by the first device.

[0023] Optionally, the second information is used to indicate the number Z of auxiliary receivers, where Z is an integer greater than or equal to M. That is, the number M of auxiliary receivers configured in the second device needs to be less than or equal to the total number of auxiliary receivers deployed on the first device. Specifically, the first device can report the second information to the second device to indicate the number Z of auxiliary receivers. This number Z can be the total number Z1 of auxiliary receivers deployed on the first device or the number Z2 of auxiliary receivers that the first device supports enabling. As one implementation, the second information can also include Z1 and Z2.

[0024] Optionally, the first device may indicate to the second device the frequency bands corresponding to one or more auxiliary receivers on the first device via third information. The third information may be sent by the first device to the second device alone, or it may be sent to the second device together with the second information, or the second information may include the third information. For example, the second information may include the indices of the four frequency bands corresponding to the four auxiliary receivers on the first device. The specific details are not limited here.

[0025] In this embodiment, the first device can report the total number of auxiliary receivers to the second device, so that when configuring the first information, the second device can determine the number of auxiliary receivers M to be activated based on the total number of auxiliary receivers Z, thereby avoiding the problem that the terminal device and the network device cannot align the number of auxiliary receivers.

[0026] Based on the first and second aspects of this application, in some possible embodiments, the first device may further receive a second signal from the second device. This second signal carries synchronization information, which is used by the first auxiliary receiver to receive signals. The second signal may be a low-power synchronization signal (LP-SS).

[0027] In this embodiment, since the LP-SS corresponds to the first auxiliary receiver, the first auxiliary receiver can correctly receive the wake-up signal from the second device, i.e., the first signal.

[0028] Based on the first and second aspects of this application, in some possible implementations, the X frequency bands are determined according to one or more of the period, time-domain offset, frequency-domain position, or sequence type of the first signal.

[0029] In this embodiment, by using different periods, different time-domain offsets, different frequency-domain positions, or different sequence types of the first signal, it is possible to distinguish which frequency band the first signal is used to wake up among X frequency bands, which is beneficial to improving the wake-up efficiency of multiple frequency bands and achieving the goal of energy saving of terminal devices.

[0030] A third aspect of this application provides a communication method. Optionally, the execution subject of this method can be a second device, which can be a network device, a component or device applied to the network device (e.g., a processor, circuit, chip, or chip system), or a logic module or software (e.g., CU, DU, or RU) capable of implementing all or part of the functions of the network device. In this method, the second device determines first information, which is used to configure M auxiliary receivers, including a first auxiliary receiver. The first auxiliary receiver is used to wake up X frequency bands out of N frequency bands of the main receiver. At least one of the X frequency bands is different from the first frequency band, where the first frequency band is the frequency band where the first auxiliary receiver is located. M is a positive integer less than or equal to N, and X is a positive integer. The second device sends the first information to the first device.

[0031] Based on a third aspect of this application, in some possible implementations, the first information includes at least one of M, an index of a first frequency band, and an index of X frequency bands.

[0032] A fourth aspect of this application provides a communication method. Optionally, the execution subject of this method may be a second device, which may be a network device, a component or device applied to the network device (e.g., a processor, circuit, chip, or chip system), or a logic module or software (e.g., CU, DU, or RU) capable of implementing all or part of the functions of the network device. In this method, the second device determines first information, which includes at least one of the following: the number M of auxiliary receivers indicated to be activated by the first device, the index of the frequency band where each auxiliary receiver is located, and the index of the frequency band that each auxiliary receiver supports for waking up the main receiver. The M auxiliary receivers include a first auxiliary receiver, which is used to wake up X frequency bands out of N frequency bands of the main receiver (or, the first auxiliary receiver supports waking up X frequency bands out of N frequency bands of the main receiver). At least one of these X frequency bands is different from the first frequency band, where the first frequency band is the frequency band where the first auxiliary receiver is located. M is a positive integer less than or equal to N, and X is a positive integer. The second device sends the first information to the first device.

[0033] Based on the third and fourth aspects of this application, in some possible implementations, the X frequency bands include the first frequency band.

[0034] Based on the third to fourth aspects of this application, in some possible implementations, the second device may also send a first signal to the first device, the first signal being located on a first frequency band, the first signal being used to instruct the first auxiliary receiver to wake up one or more of the X frequency bands of the main receiver.

[0035] Based on the third to fourth aspects of this application, in some possible implementations, the first signal satisfies at least one of the following:

[0036] The type of the first signal corresponds to the first auxiliary receiver;

[0037] The resource information of the first signal corresponds to X frequency bands; or,

[0038] The monitoring period of the first signal corresponds to X frequency bands.

[0039] Based on the third to fourth aspects of this application, in some possible implementations, if the first signal is used to instruct the first auxiliary receiver to wake up multiple frequency bands among X frequency bands of the main receiver, then the first signal occupies multiple time domain resources, and the multiple time domain resources correspond to multiple frequency bands.

[0040] In this embodiment, since the first signal is used to instruct the first auxiliary receiver to wake up multiple frequency bands among the X frequency bands of the main receiver, the second device can be configured to increase the time domain resources occupied by the first signal, thereby extending the period for the first device to monitor the first signal and thus improving the wake-up efficiency.

[0041] Based on the third and fourth aspects of this application, in some possible implementations, the M auxiliary receivers further include a second auxiliary receiver, which is used to wake up the main receiver on Y of the N frequency bands, where the Y frequency bands are different from the X frequency bands.

[0042] Based on the third to fourth aspects of this application, in some possible implementations, the second device may also receive second information from the first device, the second information being used to indicate the capabilities supported by the first device.

[0043] Based on the third and fourth aspects of this application, in some possible embodiments, the second device may further transmit a second signal to the first device. This second signal carries synchronization information, which is used by the first auxiliary receiver to receive the signal. The second signal may be an LP-SS signal.

[0044] Based on the third to fourth aspects of this application, in some possible implementations, the X frequency bands are determined according to one or more of the period, time-domain offset, frequency-domain position, or sequence type of the first signal.

[0045] Based on the third and fourth aspects of this application, in some possible embodiments, the second device may further transmit a third signal and a fourth signal, wherein one or more of the period, time-domain offset, frequency-domain position, or sequence type of the third signal and the fourth signal are different. The third signal and the fourth signal are wake-up signals sent to different terminal devices, and the third signal and the fourth signal are respectively used to wake up at least one frequency band of the main receiver of the different terminal devices.

[0046] In this embodiment, the second device sends wake-up signals with different periods, time offsets, frequency positions, or sequence types to different terminal devices, enabling the terminal devices to correctly activate the frequency band of the main receiver according to the wake-up signals, thereby improving wake-up efficiency.

[0073] First, a brief description of the network architecture on which the communication method in the embodiments of this application is based:

[0074] Please refer to Figure 1, which is a possible, non-limiting system schematic diagram. As shown in Figure 1, the communication system 10 includes an access network, such as a radio access network (RAN) 100, a core network (CN) 200, and an Internet 300. RAN 100 includes at least one RAN node (110a and 110b in Figure 1, collectively referred to as 110) and at least one terminal (120a-120j in Figure 1, collectively referred to as 120). RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1). Terminal 120 is wirelessly connected to RAN node 110. RAN node 110 is wirelessly or wired connected to core network 200. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be different physical devices, or they can be the same physical device integrating core network logical functions and radio access network logical functions.

[0075] RAN 100 can be a cellular system related to the 3rd Generation Partnership Project (3GPP), such as a 4G, 5G, or future mobile communication system. RAN 100 can also be an open-radio access network (ORAN), a cloud-radio access network (CRAN), or a Wi-Fi system. RAN 100 can also be a communication system that integrates two or more of the above systems.

[0076] RAN node 110, sometimes also referred to as access network equipment, RAN entity, or access node, constitutes part of the communication system and is used to help terminals achieve wireless access. Multiple RAN nodes 110 in communication system 10 can be of the same type or different types. In some scenarios, the roles of RAN node 110 and terminal 120 are relative. For example, network element 120i in Figure 1 can be a helicopter or drone, which can be configured as a mobile base station. For terminals 120j accessing RAN 100 through network element 120i, network element 120i is a base station; but for base station 110a, network element 120i is a terminal. RAN node 110 and terminal 120 are sometimes both referred to as communication devices. For example, network elements 110a and 110b in Figure 1 can be understood as communication devices with base station functions, and network elements 120a-120j can be understood as communication devices with terminal functions.

[0077] In one possible scenario, access network equipment includes, but is not limited to: evolved Node B (eNodeB), radio network controller (RNC), Node B (NB), base station (BS), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved NodeB, or home Node B, HNB), baseband unit (BBU), access point (AP) in a Wi-Fi system, macro base station, micro base station, wireless relay node, donor node, radio controller in a CRAN scenario, wireless backhaul node, transmission point (TP), or transmission reception point (TRP), etc., and can also be access network equipment in a 5G mobile communication system. For example, a next-generation NodeB (gNB), TRP, or TP in a new radio (NR) system; or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system; or, access network equipment can also be network nodes constituting a gNB or transmission point. Examples include a central unit (CU), a distributed unit (DU), a central unit control plane (CU-CP), a central unit user plane (CU-UP), or a radio unit (RU). CUs and DUs can be separate entities or included in the same network element, such as a BBU. RUs can be included in radio equipment or radio units, such as in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). Alternatively, access network equipment can also be a server, wearable device, vehicle, or in-vehicle equipment. For example, the access network equipment in V2X technology can be a roadside unit (RSU).It should be understood that the aforementioned TRP can be a device or module located on the network side of the aforementioned communication system and possessing corresponding communication functions. The TRP typically contains a communication module, circuit, or chip that performs the corresponding communication functions. The TRP can also be configured with program instructions for the corresponding communication functions.

[0078] It should be noted that CU (or CU-CP and CU-UP), DU, or RU may have different names in different systems, but those skilled in the art will understand their meaning. For example, in an Open Radio Access Network (ORAN) system, CU can also be called an Open Central Unit (O-CU) or an Open CU, DU can also be called an Open-Distributed Unit (O-DU), CU-CP can also be called an Open-Central Unit Control Plane (O-CU-CP), CU-UP can also be called an Open-Central Unit User Plane (O-CU-UP), and RU can also be called an Open Radio Unit (O-RU). This application does not impose any specific limitations on these details. Any of the units CU, CU-CP, CU-UP, DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0079] Optionally, for network elements in the ORAN system, each network element can implement the protocol layer functions shown in Table 1 below.

[0080] Table 1

[0081] It should be noted that in the ORAN system, the access network equipment in this application can be one or more network elements listed in Table 1 above.

[0082] The architecture of the CU and DU of the access network equipment is described below. An access network equipment includes at least one CU and at least one DU. Optionally, the access network equipment may also include at least one RU.

[0083] The following description uses an access network device consisting of one CU and one DU as an example. The CU has some core network functions and can include CU-CP and CU-UP. The CU and DU can be configured according to the protocol layer functions of the wireless network they implement. For example, the CU may be configured to implement the functions of the Packet Data Convergence Protocol (PDCP) layer and above (e.g., RRC and / or SDAP layers). The DU may be configured to implement the functions of protocol layers below the PDCP layer (e.g., RLC, MAC, and / or physical (PHY) layers). Alternatively, the CU may be configured to implement the functions of protocol layers above the PDCP layer (e.g., RRC and / or SDAP layers), and the DU may be configured to implement the functions of protocol layers below the PDCP layer (e.g., RLC, MAC, and / or PHY layers).

[0084] When a CU includes CU-CP and CU-UP, CU-CP is used to implement the control plane functions of the CU, and CU-UP is used to implement the user plane functions of the CU. For example, when a CU is configured to implement the functions of the PDCP layer, RRC layer, and SDAP layer, CU-CP is used to implement the RRC layer functions and the control plane functions of the PDCP layer, and CU-UP is used to implement the SDAP layer functions and the user plane functions of the PDCP layer.

[0085] The CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements can be access and mobility management functions (AMFs). AMFs are responsible for mobility management in the mobile network, such as terminal device location updates, terminal device registration with the network, and terminal device handover.

[0086] CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements, such as the user plane function (UPF) in a 5G system, are responsible for forwarding and receiving data in terminal devices.

[0087] The above CU and DU configurations are merely examples; the functions of the CU and DU can be configured as needed. For instance, the CU or DU can be configured to have more protocol layer functions, or only some protocol layer processing functions. For example, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of the CU or DU can be divided according to service type or other system requirements. For example, based on latency, functions that require low latency can be placed in the DU, while functions that do not require low latency can be placed in the CU.

[0088] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0089] It should be noted that the access network equipment can be a device or apparatus with a chip, or a device or apparatus with integrated circuits, or a chip, chip system, module, or control unit in the aforementioned device or apparatus; this application does not impose any specific limitation. It should also be noted that in this application, the term "access network equipment" can refer to the access network equipment itself, or to the chip, functional module, or integrated circuit within the access network equipment that performs the method provided in this application; this application does not impose any specific limitation.

[0090] A terminal can be a device or module that accesses the aforementioned communication system and has corresponding communication functions. A terminal can also be called a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart homes, smart offices, smart wearables, intelligent transportation, smart cities, etc. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, drones, helicopters, airplanes, ships, robots, robotic arms, smart home devices, transportation vehicles with wireless communication capabilities, communication modules, etc. The embodiments of this application do not limit the device form of the terminal. Terminals typically contain communication modules, circuits, or chips that perform corresponding communication functions. Terminals can also be configured with program instructions for performing corresponding communication functions.

[0091] Furthermore, the embodiments of this application can also be applied to other future communication technologies. The network architecture and service scenarios described in this application are for the purpose of more clearly illustrating the technical solutions of this application, and do not constitute a limitation on the technical solutions provided in this application. As those skilled in the art will understand, with the evolution of network architecture and the emergence of new service scenarios, the technical solutions provided in this application are also applicable to similar technical problems.

[0092] The following is a brief introduction to the concepts that may be involved in this application.

[0093] Wake-up signals (WUS) can be divided into uplink WUS (UL WUS) and downlink WUS (DL WUS). DL WUS is a signal used to wake up a terminal device, allowing it to resume from sleep mode and begin receiving data. Terminal devices typically enter sleep mode to conserve battery life. Therefore, they need to be woken up when they need to receive data. DL WUS is a short message, a special signal format, or a special signal waveform, usually sent by access network devices in the network. When a terminal device receives a DL WUS, it responds by resuming from sleep mode and beginning to receive data. In NR, WUS signals are very short, typically only a few milliseconds, allowing devices to wake up quickly and begin receiving data while conserving battery life. The counterpart to DL WUS is UL WUS, which is used to wake up access network devices from sleep mode. When a terminal device has data to send to the access network device, it sends a UL WUS to wake up the target base station.

[0094] To further reduce device power consumption, two sets of receiving modules can be introduced. As shown in Figure 2, one is the main receiver (MR), responsible for receiving regular signals, and the other is the low-power wake-up signal (LP-WUS) receiver (LP WUR). In this embodiment, MR can also be called the main receiver, and LP WUR can also be called the auxiliary receiver. MR is in a dormant state for a long time, and the device uses LP WUR to monitor LP-WUS. If LP-WUS is detected, MR is woken up. When the above modules are deployed in the terminal device, they are used to receive LP-WUS of the downlink (DL) link (DL LP-WUS). At this time, MR receives downlink signals / downlink channels from the access network device, such as synchronization signal block (SSB), channel state information reference signal (CSI-RS), physical downlink control channel (PDCCH), physical downlink shared channel (PDSCH), etc., and LP-WUR receives LP-WUS from the access network device.

[0095] In the NR Release 18 discussion, various alternative LP-WUS waveforms were proposed, including low-power signals based on orthogonal frequency division multiplexing (OFDM) modulation, frequency-shift keying (FSK) modulation signals, and on-off keying (OOK) modulation signals. All of these signals can significantly reduce the receiver power consumption of LP WUS, making it significantly lower than that of MR.

[0096] Specifically, low-power signals also include LP-SS. LP-SS has relatively weaker reception performance and a relatively limited transmission rate, but the receiver implementation is simple and low in complexity, thus its power consumption is much lower than that of the main receiver. Both LP-SS and LP-WUS are OOK signals, or OOK signals superimposed with time-domain sequences. Correspondingly, the receiver only needs to perform basic envelope monitoring or time-domain correlation monitoring to demodulate the signal, resulting in extremely low overall receiver power consumption. LP-SS is generally transmitted periodically and is mainly used for basic timing and synchronization. LP-WUS is mainly used to indicate whether terminal devices or network devices have enabled MR and to monitor related signals.

[0097] As an example, for idle terminals, LP-WUS can be used to indicate whether the terminal device monitors the paging indication. Specifically, as shown in Figure 3, the network device configures the LP-WUS monitor occasion (LO) before the paging occasion (PO) corresponding to the terminal device in each paging cycle. The terminal device monitors the LO based on the low-power receiver within each paging cycle. When LP-WUS information is detected and an indication to wake up the terminal device is received, the terminal device activates the main receiver and monitors the paging indication.

[0098] As another example, for connected terminals, LP-WUS is primarily used to indicate whether the terminal device is monitoring the PDCCH. Discontinuous reception (DRX) is a power-saving technique in wireless communication systems. The DRX mechanism allows access network devices or terminal devices to enter a sleep state when there is no data transmission requirement, reducing the power consumption of the receiving circuitry. DRX operates based on a pre-configured periodic reception mechanism. The access network device configures a Cell DRX cycle. Within this cycle, the access network device only activates the receiver at specific times to allow the network device to receive uplink signals from the terminal device (such as the physical uplink shared channel (PUSCH)) or to allow the terminal device to receive downlink signals from the network device. The receiver is turned off at other times to save power. The period during which the device activates the receiver is called the ON period or activation time, and the device's state is called the DRX ON state. The period during which the device turns off the receiver is called the OFF period or sleep period, and the device's state is called the Cell DRX OFF state. In this way, access network devices or terminal devices can receive data during discontinuous time periods and turn off the receiver when data reception is not needed, thereby achieving energy saving. DRX configuration typically includes the following parameters:

[0099] DRX cycle: The total time of the ON and OFF periods.

[0100] ON period: The time during which the receiver is activated to receive uplink signals sent by the UE.

[0101] OFF period: Time to turn off the receiver to save power.

[0102] As shown in Figure 4, the terminal device is in sleep mode during time period T1, so time period T1 is called the OFF time period. The terminal device activates the receiver during time period T2, so time period T2 is called the ON time period. Time periods T1 and T2 together form a DRX cycle.

[0103] Specifically, in one approach, the network device configures the LO during the ON period of each DRX cycle. The terminal device monitors the LO based on the low-power receiver in each DRX cycle. When LP-WUS information is detected and indicates that the terminal should not wake up, the terminal device does not start the on-duration timer in the next DRX cycle; that is, the terminal device remains in sleep mode. In another approach, the terminal device periodically monitors LP-WUS on the LO. When the LP-WUS receiver detects LP-WUS information and indicates that the terminal should wake up, the terminal starts monitoring the PDCCH based on the master receiver.

[0104] Wake-up signals can be generated independently on each band and component carrier (CC). Therefore, terminal equipment requires multiple independent LP-WUR architectures to receive wake-up signals on multiple bands or CCs. As shown in Figure 5, LP-WUR 1 is used to receive LP-WUS on band 1, thereby activating the MR to monitor the PDCCH on band 1. LP-WUR 2 is used to receive LP-WUS on band 2, thereby activating the MR to monitor the PDCCH on band 2. And so on. With 4 bands, the terminal equipment needs 4 independent LP-WUR architectures to receive LP-WUS on 4 bands.

[0105] Because terminal devices require multiple LP-WUR structures to receive wake-up signals on different bands or CCs, each LP-WUR structure needs to monitor its corresponding wake-up signal, increasing the processing complexity of the terminal device and generating additional power consumption. On the other hand, it may also cause frequency band overload issues. Since some terminal devices only support LP-WUS reception on certain frequency bands, other frequency bands are not scheduled, causing the terminal device to only reside on certain frequency bands. Taking Figure 5 as an example, assuming the terminal device has only one LP-WUR structure, i.e., only one auxiliary receiver, which supports receiving LP-WUS on band 1, the network side needs to frequently schedule LP-WUS on band 1, leading to band 1 overload.

[0106] Based on this, this application provides a method. Please refer to Figure 6, which is a schematic diagram of a communication method provided in this application. The method shown in Figure 6 is executed interactively by a first device and a second device. The first device can be a terminal device, or a component or device applied to a terminal device (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the terminal device's functions. The second device can be a network device, or a component or device applied to a network device (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the network device's functions (e.g., CU, DU, or RU). This method can be applied to the system architecture shown in Figure 2, i.e., a main receiver and at least one auxiliary receiver are deployed on the first device. The method includes:

[0107] 601. The second device sends first information to the first device. Correspondingly, the first device receives the first information from the second device.

[0108] After determining the first information, the second device sends the first information to the first device. The first information is used to configure M auxiliary receivers, including a first auxiliary receiver. The first auxiliary receiver is used to wake up X frequency bands out of N frequency bands of the main receiver. At least one of the X frequency bands is different from the first frequency band, which is the frequency band where the first auxiliary receiver is located. Here, M is a positive integer less than or equal to N, and X is a positive integer.

[0109] Since at least one of the X frequency bands is different from the first frequency band, the first auxiliary receiver can wake up the main receiver across frequency bands.

[0110] When X equals 1, the first auxiliary receiver is used to wake up one of the N frequency bands of the main receiver, and this one frequency band is different from the first frequency band. For example, assuming the first auxiliary receiver is on band 1, the first auxiliary receiver can wake up the main receiver on band 2, thereby realizing cross-band wake-up of the main receiver.

[0111] When X is greater than or equal to 2, the first auxiliary receiver is used to wake up at least 2 of the N frequency bands of the main receiver, thereby reducing the number of auxiliary receivers deployed on the first device and thus reducing the power consumption of the first device.

[0112] Optionally, when X is greater than or equal to 2, the X frequency bands include the first frequency band. Since the first frequency band is the frequency band where the first auxiliary receiver is located, it can be understood that the first auxiliary receiver supports the first frequency band for waking up the master receiver, as well as at least one frequency band other than the first frequency band, thereby realizing cross-frequency band wake-up of the master receiver.

[0113] Taking a scenario where the first device is a terminal device and the second device is a network device as an example. Specifically, the network device can instruct the terminal device on the configuration information of M auxiliary receivers, thereby enabling the terminal device to configure the M auxiliary receivers according to the configuration information.

[0114] In this embodiment, since at least one of the M auxiliary receivers (i.e., the first auxiliary receiver) supports waking up X frequency bands out of the N frequency bands of the main receiver, the number of auxiliary receivers deployed on the terminal device can be reduced, thereby reducing the power consumption of the terminal device. Simultaneously, since one auxiliary receiver can wake up X frequency bands of the main receiver, when X is greater than or equal to 2, the network device can schedule LP-WUS on at least two frequency bands through one auxiliary receiver on the terminal device, thereby reducing frequency band overload caused by the terminal device residing on a single frequency band for an extended period.

[0115] Optionally, each of the M auxiliary receivers can wake up X of the N frequency bands of the primary receiver. For example, as shown in Figure 7, the terminal device has two auxiliary receivers, LP-WUR 1 and LP-WUR 2. LP-WUR 1 is on band 1, and LP-WUR 2 is on band 3. LP-WUR 1 supports waking up bands 1 and 2 of the primary receiver, while LP-WUR 2 supports waking up bands 3 and 4. Therefore, the terminal device only needs to deploy two auxiliary receivers to support waking up the primary receiver's four frequency bands, thereby reducing the number of auxiliary receivers and hardware complexity, and consequently reducing the power consumption of the terminal device.

[0116] Optionally, the first auxiliary receiver can wake up N frequency bands of the main receiver. For example, as shown in Figure 8, the terminal device has one auxiliary receiver, LP-WUR 1, and the main receiver supports 4 frequency bands, i.e., N=4. LP-WUR 1 operates on band 2, and it supports waking up bands 1, 2, 3, and 4 of the main receiver. In other words, one auxiliary receiver on the terminal device supports waking up all frequency bands of the main receiver, thereby reducing terminal power consumption.

[0117] The first information is used to configure the auxiliary receivers on the first device, and therefore the first information can also be referred to as configuration information. The first information includes at least one of the following: the number M of auxiliary receivers activated by the first device, the index of the frequency band where each auxiliary receiver is located, and the index of the MR frequency band that each auxiliary receiver supports for wake-up. For example, for the first auxiliary receiver, the first information includes at least one of M, the index of the first frequency band, and the indexes of X frequency bands.

[0118] For example, if the first auxiliary receiver is on band 1 and supports wake-up of four frequency bands, namely band 1, band 2, band 3, and band 4, then one possible implementation of the first information is as follows:

[0119] Number of auxiliary receivers activated by the first device: 1;

[0120] The frequency band index of the first auxiliary receiver: band 1;

[0121] The indexes of the frequency bands that the first auxiliary receiver supports for wake-up are: band 1, band 2, band 3, and band 4.

[0122] It should be noted that this application uses frequency bands as an example for explanation. In practical applications, frequency bands can be replaced by cells or CCs, and the index of a frequency band can be replaced by the index of a cell or the index of a CC. No specific restrictions are imposed here.

[0123] Optionally, each of the M auxiliary receivers supports different wake-up frequency bands. For example, the M auxiliary receivers may also include a second auxiliary receiver, which is used to wake up Y frequency bands out of the N frequency bands of the main receiver. These Y frequency bands are different from the X frequency bands. Taking Figure 7 as an example, the first auxiliary receiver is LP-WUR 1, and the second auxiliary receiver is LP-WUR 2. The first auxiliary receiver is used to wake up bands 1 and 2, and the second auxiliary receiver is used to wake up bands 3 and 4.

[0124] It should be noted that the Y frequency bands can be completely different from the X frequency bands, or only partially different. Specifically, "completely different from the X frequency bands" means that no single frequency band in the Y frequency bands is the same as any frequency band in the X frequency bands. "Partially different from the X frequency bands" means that at least one frequency band in the Y frequency bands is different from any frequency band in the X frequency bands.

[0125] For example, if the first auxiliary receiver is used to wake up band 1 and band 2, and the second auxiliary receiver is used to wake up band 3 and band 4, then the Y frequency bands are completely different from the X frequency bands.

[0126] For example, if the first auxiliary receiver is used to wake up bands 1, 2, and 3, and the second auxiliary receiver is used to wake up bands 2, 3, and 4, then the Y frequency bands will differ from the X frequency bands. Specific details are not limited here.

[0127] It should be noted that the number of frequency bands that each of the M auxiliary receivers can support waking up the master receiver can be different. For example, the first auxiliary receiver may be used to wake up the master receiver on 3 frequency bands, and the second auxiliary receiver may be used to wake up the master receiver on 4 frequency bands. The specific number is not limited here.

[0128] Optionally, the unactivated secondary receiver can be in any of the following states: ultra-deep sleep, deep sleep, light sleep, or micro sleep, thereby saving power consumption of the terminal device.

[0129] 602. The first device configures M auxiliary receivers according to the first information.

[0130] The first device activates M auxiliary receivers based on the first information to monitor the corresponding WUS.

[0131] Optionally, the first device may use M active auxiliary receivers to perform WUS monitoring in the corresponding period or frequency band according to the WUS configuration information.

[0132] Specifically, the WUS configuration information is configured by the second device and sent to the first device. This WUS configuration information includes at least one of the following: WUS type, WUS monitoring cycle, and WUS resources.

[0133] Optionally, the type of WUS matches the number M of auxiliary receivers activated by the first device. For example, M auxiliary receivers correspond to M types of WUS. The type of WUS can be understood as an index of the WUS. There is a one-to-one correspondence between the type of WUS and the number of M auxiliary receivers; for example, WUS1 corresponds to LP-WUR 1, WUS2 corresponds to LP-WUR 2, WUS 3 corresponds to LP-WUR 3, ..., WUS M corresponds to LP-WUR M, thus enabling the M auxiliary receivers to correctly perform WUS monitoring.

[0134] Optionally, the second device can be configured to configure the WUS monitoring period for the auxiliary receivers. Different auxiliary receivers can correspond to different monitoring periods, or they can correspond to the same monitoring period. For example, if the first auxiliary receiver is used to wake up the four frequency bands of the main receiver, then the second device can be configured with four different WUS monitoring periods, each corresponding to one of the four frequency bands. Alternatively, if the first auxiliary receiver is used to wake up the four frequency bands of the main receiver, then the second device can be configured with two different WUS monitoring periods, each corresponding to one of the two frequency bands. The specific configuration is not limited here. The two frequency bands corresponding to one WUS monitoring period can be distinguished by period, time-domain offset, or frequency-domain position, as described later.

[0135] One monitoring period can correspond to one or more frequency bands on a time domain unit. This time domain unit can be a symbol, slot, sensing slot, mini-slot, partial slot, sub-frame, frame, radio frame, etc., and is not limited here. The symbol can be an OFDM symbol.

[0136] Optionally, WUS resources can be time-domain resources, frequency-domain resources, or spatial-domain resources. The number of frequency bands supported by the secondary receiver for wake-up is related to the number of bands. For example, if WUS is used to instruct the first secondary receiver to wake up the primary receiver in one frequency band, the frequency domain bandwidth of WUS is 10MHz; if WUS is used to instruct the first secondary receiver to wake up the primary receiver in two frequency bands, the frequency domain bandwidth of WUS is 20MHz. For another example, if WUS is used to instruct the first secondary receiver to wake up the primary receiver in one frequency band, WUS occupies one symbol; if WUS is used to instruct the first secondary receiver to wake up the primary receiver in two frequency bands, WUS occupies two symbols. For yet another example, if WUS is used to instruct the first secondary receiver to wake up the primary receiver in one frequency band, WUS occupies one transport layer; if WUS is used to instruct the first secondary receiver to wake up the primary receiver in two frequency bands, WUS occupies two transport layers. Specific limitations are not specified here.

[0137] The complex symbols (modulated symbols) obtained by scrambling and modulating one or two codewords are mapped to one or more transmission layers, often simply called layers. Transmission layers are typically mapped to antenna ports, hence they can also be referred to as antenna ports. Each layer corresponds to one valid data stream. The number of transmission layers, or layer number, is called the "transmission order" or "transmission rank." The transmission rank can change dynamically. The number of layers must be less than or equal to the minimum of the number of transmit antenna ports and the number of receive antenna ports, i.e., "number of layers ≤ min(number of transmit antenna ports, number of receive antenna ports)". In NR downlink communication, the number of transmission layers generally equals the number of antenna ports. Downlink control information indicates the number of layers and / or antenna ports (or, further, the number of each antenna port) used for data and demodulation reference signal (DMRS) transmission. In NR, antenna ports can also correspond to transmission configuration indicators (TCI), beamforming, etc. For example, one TCI corresponds to multiple antenna ports, or one beam corresponds to multiple antenna ports.

[0138] Optionally, the embodiment shown in FIG6 further includes step 600. Step 600 may be performed before step 601.

[0139] 600. The first device sends second information to the second device. Correspondingly, the second device receives the second information from the first device.

[0140] The second piece of information is used to indicate the capability supported by the first device.

[0141] Optionally, the second information is used to indicate the number Z of auxiliary receivers, where Z is an integer greater than or equal to M. That is, the number M of auxiliary receivers configured by the second device needs to be less than or equal to the total number of auxiliary receivers deployed on the first device. Specifically, the first device may report the second information to the second device to indicate the number Z of auxiliary receivers, which may be the total number Z1 of auxiliary receivers deployed on the first device or the number Z2 of auxiliary receivers that the first device supports in operation. In some embodiments, the second information may also include Z1 and Z2.

[0142] Optionally, the first device may indicate to the second device the frequency bands corresponding to one or more auxiliary receivers on the first device via third information. The third information may be sent by the first device to the second device alone, or it may be sent to the second device together with the second information, or the second information may include the third information. For example, the second information may include the indices of the four frequency bands corresponding to the four auxiliary receivers on the first device, and the specifics are not limited here.

[0143] The content of the second information mentioned above is only an example. In practical applications, the second information may also include capability information of other first devices, which is not limited here.

[0144] Optionally, the embodiment shown in FIG6 further includes step 603. Step 603 may be performed after step 602.

[0145] 603. The second device sends a second signal to the first device. Correspondingly, the first device receives the second signal from the second device.

[0146] In one possible implementation, the first device receives a second signal via a first auxiliary receiver, the second signal being used to carry synchronization information.

[0147] Specifically, the second signal is LP-SS, which corresponds to the first auxiliary receiver, enabling the first auxiliary receiver to accurately monitor WUS.

[0148] Optionally, the embodiment shown in FIG6 further includes step 604. Step 604 may be performed after step 602.

[0149] 604. The second device sends a first signal to the first device. Correspondingly, the first device receives the first signal from the second device.

[0150] The first signal can be WUS or LP-WUS. Based on the first information, the second device periodically or non-periodically transmits the corresponding WUS or LP-WUS. When the auxiliary receiver of the first device detects WUS or LP-WUS, it instructs the MR of the first device to start PDCCH monitoring in the corresponding frequency band.

[0151] In one possible implementation, the first device can determine which frequency bands the MR will be activated based on the period, time-domain offset, or frequency-domain position of the first signal. For example, if the time-domain offset pattern of the first signal is case 1 as shown in Figure 9, the first auxiliary receiver activates the MR to monitor the PDCCH on band 1; if the time-domain offset pattern of the first signal is case 2 as shown in Figure 9, the first auxiliary receiver activates the MR to monitor the PDCCH on band 2. The time-domain offset in cases 1 and 2 can be in units of time-domain units, which can be symbols, time slots, sensing time slots, mini-time slots, partial time slots, subframes, frames, radio frames, etc., and the symbols can be OFDM symbols.

[0152] Optionally, the correspondence between the period, time-domain offset, or frequency-domain position of the first signal and the X frequency bands can be predefined by the protocol or indicated by the second device; the specific details are not limited here.

[0153] In another possible implementation, the first device can determine which frequency bands to wake up the MR based on the sequence type of the first signal. For example, the second device can design the WUS based on different OOKs to match different auxiliary receivers. For instance, if the first signal includes four sequences in a set of OOKs (which can be represented as OOK-4 (M=4)), as shown in Figure 10, then the first auxiliary receiver activates the master receiver to monitor the PDCCH on band 1 based on the first signal; if the first signal includes two sequences in a set of OOKs (which can be represented as OOK-4 (M=2)), as shown in Figure 11, then the first auxiliary receiver activates the master receiver to monitor the PDCCH on band 2 based on the first signal.

[0154] Optionally, if the first signal is used to instruct the first auxiliary receiver to simultaneously wake up multiple frequency bands out of X frequency bands, then the first signal occupies multiple time-domain resources, and these multiple time-domain resources correspond to multiple frequency bands. Specifically, for carrier aggregation (CA) transmission, the first device can simultaneously activate multiple frequency bands to monitor the PDCCH. As a possible implementation, the second device can be configured to increase the time-domain symbol length of the WUS, thereby lengthening the monitoring period of the corresponding auxiliary receiver.

[0155] Optionally, the wake-up timing for multiple frequency bands can be predefined by the protocol or indicated by the network device. In one possible implementation, multiple frequency bands can be woken up simultaneously, meaning the terminal device's MR simultaneously enables multi-band / CC monitoring. In another possible implementation, the wake-up timing can be determined based on some criterion. For example, wake-up can be performed sequentially according to the frequency band index number. Another example is prioritizing the wake-up of the frequency band where the secondary receiver is located.

[0156] Optionally, the first signal satisfies at least one of the following:

[0157] The type of the first signal corresponds to the first auxiliary receiver;

[0158] The resource information of the first signal corresponds to X frequency bands; or,

[0159] The monitoring period of the first signal corresponds to X frequency bands.

[0160] The correspondence between the first signal and the first auxiliary receiver, the correspondence between the resource information of the first signal and the X frequency bands, and the correspondence between the monitoring period of the first signal and the X frequency bands can be found in the description of WUS resources in the above embodiments, and will not be repeated here.

[0161] It should be noted that the above description refers to the scenario where a network device sends a WUS to a single terminal device. In practical applications, a network device can send WUS to multiple terminal devices, and the multiple WUS sent by the network device are used to activate at least one frequency band of the main receiver on different terminal devices.

[0162] For example, the second device sends a third signal to the third device and a fourth signal to the fourth device. The third and fourth devices can be terminal devices, components or devices applied to the terminal devices (e.g., processors, circuits, chips, or chip systems), or logic modules or software capable of implementing all or part of the terminal device's functions. The third and fourth signals differ in one or more of the following: period, time-domain offset, frequency-domain position, or sequence type.

[0163] For example, the time-domain offset mode of the third signal can be shown as case 1 in Figure 9, and the time-domain offset mode of the fourth signal can be shown as case 2 in Figure 9.

[0164] For example, the sequence type of the third signal can be as shown in Figure 10, and the sequence type of the fourth signal can be as shown in Figure 11. The specifics will not be elaborated here.

[0165] The communication method in the embodiments of this application has been described above. The communication device in the embodiments of this application is described below. Referring to Figure 12, the communication device 1200 can be used to execute the process performed by the first device in the embodiment shown in Figure 6. For details, please refer to the relevant descriptions in the foregoing method embodiments. The communication device 1200 can be a terminal device, a component or device applied to a terminal device (e.g., a processor, circuit, chip, or chip system), or a logic module or software capable of implementing all or part of the functions of the terminal device.

[0166] The communication device 1200 includes an interface module 1201 and a processing module 1202.

[0167] The processing module 1202 is used for data processing. The interface module 1201 can implement corresponding communication functions. The interface module 1201 can also be called a communication interface or a communication module.

[0168] Optionally, the communication device 1200 may further include a storage module, which can be used to store computer programs / instructions and / or data. The processing module 1202 can read the computer programs / instructions and / or data in the storage module so that the communication device 1200 can implement the aforementioned method embodiments.

[0169] The communication device 1200 can be used to perform the actions performed by the first device in the above method embodiments. For example, it can be the first device or a communication module in the first device, or a circuit or chip in the first device responsible for communication functions. The communication device 1200 can be the first device or a component configurable on the first device. The processing module 1202 is used to perform processing-related operations on the first device side in the above method embodiments. The interface module 1201 is used to perform receiving-related operations on the first device side in the above method embodiments.

[0170] Optionally, the interface module 1201 may include a sending module and a receiving module. The sending module is used to perform the sending operation in the above method embodiments. The receiving module is used to perform the receiving operation in the above method embodiments.

[0171] It should be noted that the communication device 1200 may include a transmitting module but not a receiving module. Alternatively, the communication device 1200 may include a receiving module but not a transmitting module. Specifically, it depends on whether the above-described scheme performed by the communication device 1200 includes both transmitting and receiving actions. For example, the communication device 1200 is used to perform the actions performed by the first device in the embodiment shown in FIG. 6. For details, please refer to the relevant descriptions in the embodiment shown in FIG. 6; these will not be elaborated upon here.

[0172] For example, the communication device 1200 is used to execute the following scheme:

[0173] Interface module 1201 is used to receive first information, which is used to configure M auxiliary receivers. The M auxiliary receivers include a first auxiliary receiver. The first auxiliary receiver is used to wake up X frequency bands out of N frequency bands of the main receiver. Among the X frequency bands, at least one frequency band is different from the first frequency band. The first frequency band is the frequency band where the first auxiliary receiver is located. M is a positive integer less than or equal to N, and X is a positive integer.

[0174] Processing module 1202 is used to configure M auxiliary receivers according to the first information.

[0175] In one possible implementation, the X frequency bands include the first frequency band.

[0176] In another possible implementation, the first information includes at least one of M, the index of the first frequency band, and the indices of X frequency bands.

[0177] In another possible implementation, the interface module 1201 is also used to receive a first signal located on a first frequency band. The first signal is used to instruct the first auxiliary receiver to wake up one or more of the X frequency bands of the main receiver.

[0178] In another possible implementation, the first signal satisfies at least one of the following:

[0179] The type of the first signal corresponds to the first auxiliary receiver;

[0180] The resource information of the first signal corresponds to X frequency bands; or,

[0181] The monitoring period of the first signal corresponds to X frequency bands.

[0182] In another possible implementation, the M auxiliary receivers also include a second auxiliary receiver, which is used to wake up Y of the N frequency bands of the main receiver. The Y frequency bands are different from the X frequency bands.

[0183] In another possible implementation, the interface module 1201 is also used to send second information, which is used to indicate the capabilities supported by the first device.

[0184] Optionally, the second information is used to indicate the number Z of auxiliary receivers, where Z is an integer greater than or equal to M. That is, the number M of auxiliary receivers configured in the second device needs to be less than or equal to the total number of auxiliary receivers deployed on the first device. Specifically, the first device can report the second information to the second device to indicate the number Z of auxiliary receivers. This number Z can be the total number Z1 of auxiliary receivers deployed on the first device or the number Z2 of auxiliary receivers that the first device supports enabling.
