Description

Technical Field

[0001] This application relates to the field of communications, and more particularly, to a communication method and a communication device in the field of communications. Background Art

[0002] With the development of communication systems, terminal devices can support communications at higher rates or with larger bandwidths. However, higher rates or larger bandwidths consume relatively more energy, so there are relatively high requirements for energy conservation of terminal devices. To reduce the energy consumption of terminal devices, a low-power consumption mechanism has been proposed. When there is no data transmission, the terminal device can be in a low-power state. When there is data transmission, the network device can send a wake-up signal to the terminal device to wake it up. After the network device sends the wake-up signal, it can continue to send the physical downlink control channel (PDCCH) to the terminal device. Regardless of whether the terminal device receives the wake-up signal, the network device will continue to send the PDCCH, resulting in a waste of network resources. Summary of the Invention

[0003] Embodiments of this application provide a communication method and a communication device, which can avoid wasting network resources.

[0004] In a first aspect, a communication method is provided. The communication method is applied to a first device and includes: receiving first indication information for waking up the first device. Before receiving the first indication information, the first device is in a sleep state; sending second indication information for indicating that the first device has been woken up. When the first device sends the second indication information, the first device has been woken up by the first indication information; receiving the physical downlink control channel PDCCH and / or the physical downlink data channel PDSCH.

[0005] In the above solution, after the first device receives the first indication information, it can enter the wake-up state from the sleep state according to the first indication information. After the first device enters the wake-up state, it can send the second indication information so that the second device can know that the first device has entered the wake-up state. Thus, the second device can send the PDCCH and / or the PDSCH to the first device; if the second device does not receive the second indication information, the second device may not send the PDCCH and / or the PDSCH, avoiding waste of network resources.

[0006] Optionally, the second device may be a network device, and the first device is a terminal device. For example, the first indication information may be LP-WUS for waking up the terminal device and enabling the terminal device to enter the wake-up state.

[0007] Optionally, the second device may be an auxiliary circuit in the terminal device, and the first device may be a main circuit in the terminal device. The auxiliary circuit may send a first indication message to the main circuit to wake up the main circuit, so that the main circuit can enter the wake-up state from the sleep state. For example, the first indication message may be a pulse signal or the like. Optionally, before the auxiliary circuit sends the first indication message to the main circuit, the auxiliary circuit may receive LP-WUS from the network device. After receiving the LP-WUS, the auxiliary circuit may trigger the auxiliary circuit to send the first indication message to the main circuit.

[0008] In some possible implementation manners, sending the second indication message includes: sending the second indication message through a physical uplink control channel PUCCH; or, sending the second indication message through a physical uplink shared channel PUSCH; or, sending the second indication message through a physical random access channel PRACH.

[0009] In the above solution, the first device may send the second indication message through the PUCCH or the PUSCH or the PRACH. In this way, a way to send the second indication message is provided. Optionally, the protocol may specify or the second device may configure for the first device which way among these ways to send the second indication message.

[0010] In some possible implementation manners, the second indication message included in the PUCCH corresponds to a first sequence;

[0011] Wherein, the PUCCH includes an uplink control information sequence, and the uplink control information sequence includes the first sequence.

[0012] In the above solution, the uplink control information sequence may include the first sequence corresponding to the second indication message.

[0013] In some possible implementation manners, the first bit position for carrying hybrid automatic repeat request HARQ in the PUCCH is used to carry the first sequence; or, the second bit position for carrying scheduling request SR in the PUCCH is used to carry the first sequence.

[0014] In the above solution, the first bit position for carrying HARQ in the PUCCH may be used to carry the first sequence or the second bit position for carrying HARQ in the PUCCH may be used to carry the first sequence. In this way, it is not necessary to change the format of the PUCCH, and the bit positions of HARQ or SR in the PUCCH can be reused, thereby saving overhead.

[0015] In some possible implementation manners, the uplink control information sequence further includes a Hybrid Automatic Repeat reQuest (HARQ) feedback sequence, and the first sequence is located after the HARQ feedback sequence in the uplink control information sequence, or the first sequence is located before the HARQ feedback sequence in the uplink control information sequence.

[0016] In some possible implementation manners, the uplink control information sequence further includes a HARQ feedback sequence and a Scheduling Request (SR) sequence. The first sequence is located after the SR sequence in the uplink control information sequence, and the HARQ feedback sequence is located before the SR sequence in the uplink control information sequence. Or, the first sequence is located before the HARQ feedback sequence in the uplink control information sequence, and the HARQ feedback sequence is located before the SR sequence in the uplink control information sequence. Or, the HARQ feedback sequence is located before the first sequence in the uplink control information sequence, and the first sequence is located before the SR sequence in the uplink control information sequence.

[0017] In some possible implementation manners, the uplink control information sequence further includes a Channel State Information (CSI) sequence, and the first sequence is located before or after the CSI sequence in the uplink control information.

[0018] In some possible implementation manners, the uplink control information sequence further includes the HARQ feedback sequence, the SR sequence, and the CSI sequence. The first sequence is located before the HARQ feedback sequence in the uplink control information sequence, the HARQ feedback sequence is located before the SR sequence in the uplink control information sequence, and the SR sequence is located before the CSI sequence in the uplink control information sequence. Or, the HARQ feedback sequence is located before the first sequence in the uplink control information sequence, the first sequence is located before the SR sequence in the uplink control information sequence, and the SR sequence is located before the CSI sequence. Or, the HARQ feedback sequence is located before the SR sequence in the uplink control information sequence, the SR sequence is located before the first sequence in the uplink control information sequence, and the first sequence is located before the CSI sequence in the uplink control information sequence. Or, the HARQ feedback sequence is located before the SR sequence in the uplink control information sequence, the SR sequence is located before the CSI sequence in the uplink control information sequence, and the CSI sequence is located before the first sequence.

[0019] In some possible implementation manners, the first indication information is further used to indicate a first time-frequency resource; wherein, sending the second indication information includes: sending the second indication information on the first time-frequency resource.

[0020] In the above solution, the first indication information sent by the second device may indicate the first time-frequency resource, and the first device may send the second indication information on the first time-frequency resource, thereby providing a method for determining the time-frequency resource for sending the second indication information.

[0021] In some possible implementation manners, the sending of the second indication information includes: sending the second indication information at the nearest reporting moment after the first preset time period. Optionally, the first preset time period is greater than the duration for which the first device is awakened.

[0022] In the above solution, the first device may send the second indication information at the nearest reporting moment after the first preset time period. For example, the first preset time period is greater than the duration for which the first device is awakened. In this way, the first device may send the second indication information at the reporting moment after the first device is awakened.

[0023] Optionally, the second device may configure one or more reporting moments for the first device.

[0024] In some possible implementation manners, the sending of the second indication information includes: sending the second indication information at the nearest reporting moment after the first device is awakened within the first preset time period. Optionally, the first preset time period is equal to the sum of the duration for which the first device is awakened and the first duration, where the first duration is the duration between the first moment and the second moment when the first device is awakened, and the second moment is the farthest reporting moment among the multiple consecutive reporting moments closest to the first moment.

[0025] In the above solution, the first device may send the second indication information at the nearest reporting moment when the first device is awakened within the first preset time period, thereby providing a method for sending the second indication information.

[0026] In some possible implementation manners, the first indication information is further used to indicate the first preset time period.

[0027] In the above solution, the first indication information for awakening the first device may also indicate the first preset time period. For example, the first indication information is LPWUS, and LPWUS can awaken the first device and also indicate the first preset time period, avoiding the need for the second device to use a dedicated indication information to indicate the first preset time period.

[0028] In some possible implementation manners, the communication method further includes: receiving third indication information, where the third indication information is used to indicate the first preset time period.

[0029] In the above solution, the second device may send dedicated third indication information to indicate the first preset time period.

[0030] Optionally, there is no restriction on the order in which the second device sends the third indication information and the first indication information.

[0031] In some possible implementation manners, the third indication information is carried in a low-power synchronization signal LP-SS; alternatively, the third indication information is carried in a system information block SIB; alternatively, the third indication information is carried in a radio resource control RRC message; alternatively, the third indication information is carried in a media access control MAC control element CE; alternatively, the third indication information is carried in downlink control information DCI.

[0032] In the above solution, the third indication information sent by the second device may be carried in LP-SS or SIB or RRC message or MAC CE or DCI, thus providing a way for the second device to send the third indication information.

[0033] In some possible implementation manners, the communication method further includes: if the PDCCH or the PDSCH is not received within a second preset time period after the first preset time period, the second indication information is sent again.

[0034] In the above solution, if the first device does not receive the PDCCH and does not receive the PDSCH within the second preset time period, it means that the second device has not received the second indication information. The first device can try to continue sending the second indication information to avoid the situation where after the first device fails to send the second indication information, the second device cannot know whether the first device is awakened, resulting in the second device being unable to continue sending the PDCCH and / or the PDSCH.

[0035] In some possible implementation manners, the communication method further includes: if the PDCCH or the PDSCH is not received after the first preset time period, the second indication information is sent again; if the first device has continuously sent the second indication information N times and then has not received the PDCCH or the PDSCH, the second indication information is stopped being sent, where N is a positive integer.

[0036] In the above solution, when the first device has continuously sent the second indication information N times and still has not received the PDCCH, or still has not received the PDSCH, or has neither received the PDCCH nor received the PDSCH, the first device stops sending the second indication information to avoid the problem of resource waste caused by the first device continuously sending the second indication information all the time.

[0037] In some possible implementations, before sending the second indication information, the communication method further includes: receiving fourth indication information for indicating that the first device reports being woken up; wherein, the sending of the second indication information includes: sending the second indication information according to the fourth indication information.

[0038] In the above solution, the second device can use the fourth indication information to indicate to the first device that the first device can report being woken up. The first device can determine that the first device reports being woken up according to the fourth indication information. Therefore, the first device can send the second indication information, avoiding the problem of resource waste caused by the first device blindly sending the second indication information without the authorization of the second device.

[0039] In some possible implementations, the communication method further includes: sending fifth indication information to the second device, where the fifth indication information is used to indicate that the first device supports reporting being woken up; wherein, the receiving of the fourth indication information includes: receiving the fourth indication information sent by the second device according to the fifth indication information.

[0040] In the above solution, the first device can send the fifth indication information to the second device to indicate that the first device supports reporting being woken up or indicates that the first device has the ability to report being woken up. Therefore, the second device can send the fourth indication information to the first device according to the fifth indication information to indicate that the first device can report being woken up.

[0141] It should be understood that the manners, situations, categories, and the division of embodiments in the embodiments of the present application are only for the convenience of description and should not constitute a special limitation. Features in various manners, categories, situations, and embodiments can be combined without conflict.

[0142] It should also be understood that the "first", "second", and "third" in the embodiments of the present application are only for distinction and should not constitute any limitation to the present application. It should also be understood that in various embodiments of the present application, the magnitudes of the sequence numbers of the processes do not mean the sequence of execution. The execution sequence of each process should be determined according to its function and internal logic and should not constitute any limitation to the implementation process of the embodiments of the present application.

[0143] In the embodiments of the present application, for the number of nouns, unless otherwise specified, it means "singular noun or plural noun", that is, "one or more". "At least one" means one or more, and "multiple" means two or more. "And / or" describes the association relationship of associated objects and indicates 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, where A and B can be singular or plural. The character " / " generally means that the associated objects before and after are in an "or" relationship. For example, A / B means: A or B. "At least one (item)" or its similar expression means any combination of these items, including any combination of single item (item) or plural items (items). For example, at least one (item) of a, b, or c means: a, b, c, a and b, a and c, b and c, or a, b, and c, where a, b, and c can be single or multiple.

[0144] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally further include other steps or units not listed, or may optionally further include other steps or units inherent to these processes, methods, products, or devices.

[0145] It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0146] The methods and devices provided in the embodiments of the present application are based on the same or similar technical concepts. Since the principles of solving problems by the methods and devices are similar, the implementation of the devices and methods can be referred to each other, and the repeated parts will not be elaborated.

[0147] Figure 1 It is a schematic diagram of a communication system applicable to the embodiments of the present application. As Figure 1 shown, the wireless communication system may include a network device 110 and one or more terminal devices (such as Figure 1 the terminal device 121 and the terminal device 122 shown therein) for communication. When the network device 110 sends a signal, the network device 110 is the transmitting end, and the terminal device 121 or the terminal device 122 is the receiving end. Conversely, when the terminal device 121 or the terminal device 122 sends a signal, the terminal device 121 or the terminal device 122 is the transmitting end, and the network device 110 is the receiving end. Optionally, the terminal device 121 and the terminal device 122 can also communicate. When the terminal device 121 sends a signal to the terminal device 122, the terminal device 121 is the transmitting end, and the terminal device 122 is the receiving end. Conversely, when the terminal device 122 sends a signal to the terminal device 121, the terminal device 122 is the transmitting end, and the terminal device 121 is the receiving end.

[0148] The terminal device 121 or the terminal device 122 may also be referred to as a terminal, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), a roadside unit (RSU), etc. The terminal device in the embodiments of the present application may be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a robotic arm, a smart home device, a speaker, etc. It may also be a wireless terminal applied to scenarios such as device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality (VR), augmented reality (AR), industrial control, self-driving, remote medical, smart grid, transportation safety, smart city, smart wear, smart transportation, and smart home. In the present application, the foregoing terminal device and the chip applicable to the foregoing terminal device are collectively referred to as the terminal device. It should be understood that the embodiments of the present application do not limit the specific technologies and specific device forms adopted by the terminal device.

[0149] The network device 110 can be a device in a wireless network, and the network device 110 can also be referred to as a network apparatus. For example, the network device 110 can be a radio access network (RAN) node that connects a terminal device to a wireless network, and can also be referred to as an access network device. The network device 110 includes but is not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), 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 wireless fidelity (WIFI) system, wireless relay node, wireless backhaul node, transmission point (TP), reception point (RP), or transmission and reception point (TRP), etc., and can also be a network device in a 5G mobile communication system or a network device in other future network systems. For example, the next generation NodeB (gNB) in the NR system, transmission reception point (TRP), TP; or, one or a group of (including multiple antenna panels) antenna panels of a base station in a 5G mobile communication system; or, the network device 110 can also be a network node that constitutes a gNB or a transmission point. For example, BBU, or distributed unit (DU), etc.

[0150] In some deployments, the network device 110 may include a centralized unit (CU) and a distributed unit (DU). The network device 110 may also include an active antenna unit (AAU). The CU implements some functions of the gNB, and the DU implements some functions of the gNB. For example, the CU is responsible for processing non-real-time protocols and services and implementing the functions of the radio resource control (RRC) layer. The DU is responsible for processing physical layer protocols and real-time services and implementing the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical (PHY) layer. In some deployments, the CU may also be divided into a centralized unit control plane (CU-CP) node and a centralized unit user plane (CU-UP) node. Among them, the CU-CP is responsible for control plane functions, and the CU-UP is responsible for user plane functions. For example, the CU-CP and the CU-UP may be implemented by different functional entities and connected through an E1 interface. The CU-CP and the CU-UP may be coupled with the DU to jointly complete the functions of the base station. The control plane CU-CP of the CU also includes a further split architecture, that is, the existing CU-CP is further split into CU-CP1 and CU-CP2. Among them, CU-CP1 includes various radio resource management functions, and CU-CP2 only includes radio resource control (RRC) functions and PDCP-C functions (i.e., the basic functions of control plane signaling at the packet data convergence protocol (PDCP) layer).

[0151] Figure 1 The communication system shown may apply to 4G, 5G, 6G, or future communication systems, etc., and the embodiments of this application do not limit this.

[0152] For the convenience of description in the following embodiments, the numbers of the devices are omitted. For example, "terminal device" means "terminal device 121 or terminal device 122", and "network device" means "network device 110".

[0153] In the embodiments of this application, the terminal device and the network device are taken as examples for description. In actual applications, the embodiments of this application can also be applied to other scenarios, such as the D2D scenario or the satellite communication scenario.

[0154] With the development of communication systems, terminal devices can support communication at higher rates or with larger bandwidths. However, higher rates or larger bandwidths consume relatively more energy, so there are relatively high requirements for energy conservation of terminal devices. To reduce the energy consumption of terminal devices, a low-power mechanism is proposed. When there is no data transmission, the terminal device can be in a low-power state. When there is data transmission, the network device can send a low-power wake-up signal (LP-WUS) to the terminal device to wake it up. After sending the LP-WUS, the network device can continue to send the physical downlink control channel (PDCCH) to the terminal device. Regardless of whether the terminal device receives the LP-WUS, the network device will continue to send the PDCCH, which will cause waste of network resources. That is to say, regardless of whether the terminal device is in a wake-up state, the network device will continue to send the PDCCH to the terminal device. If the terminal device is in a low-power state and is not woken up by the LP-WUS, the terminal device cannot process the PDCCH, resulting in the invalidation of the PDCCH sent by the network device, thus causing waste of network resources.

[0155] In an embodiment of the present application, after the first device is woken up, it can send second indication information to the second device. The second indication information is used to indicate that the first device has been woken up. After receiving the second indication information, the second device sends the PDCCH and / or PDSCH to the first device. In this way, the problem of waste of network resources caused by the second device blindly sending the PDCCH and / or PDSCH is avoided. For example, the first device is a terminal device or the main circuit in the terminal device.

[0156] The following briefly introduces the terms used in the present application.

[0157] Sleep state

[0158] The main circuit can be in a sleep state. Alternatively, when the first device is in a sleep state, it means that the main circuit of the first device is in a sleep state. For example, the main circuit can also be referred to as the main link, the main communication module, or the main receiver (MR). When the first device is in a sleep state, it can be understood as the first device being in a low-power state. The first device can include a main circuit and an auxiliary circuit. The auxiliary circuit can also be referred to as the auxiliary link, the auxiliary communication module, or the low-power auxiliary receiver (LP-WUR). When the first device is in a sleep state, it can be understood that the main circuit is in a sleep state and the auxiliary circuit is in a wake-up state. The first device in the sleep state cannot receive the PDCCH and / or PDSCH, but can receive the LP-WUS. That is to say, the auxiliary circuit can receive the LP-WUS, but the main circuit cannot receive the PDCCH and / or PDSCH. As Figure 2 shown, the first device includes a main circuit and an auxiliary circuit. When the first device is in a sleep state, the main circuit is in a sleep state and the auxiliary circuit is in a wake-up state.

[0159] Wake-up state

[0160] When the first device is in a wake-up state, it means that the main circuit of the first device is turned on, or the main circuit leaves the sleep state, or the main circuit enters the wake-up state, etc. Among them, the main circuit can also be referred to as the main link, the main communication module, etc. The first device can include a main circuit and an auxiliary circuit. The auxiliary circuit can also be referred to as the auxiliary link, the auxiliary communication module, or the low-power auxiliary receiver (LP-WUR). When the first device is in a wake-up state, it can be understood that the first device is in a working state. When the first device is in a wake-up state, it can be understood that the main circuit is in a wake-up state. The first device in the wake-up state can receive the PDCCH and / or PDSCH. As Figure 2 shown, the first device includes a main circuit and an auxiliary circuit. When the first device is in a sleep state, the main circuit is in a sleep state and the auxiliary circuit is in a wake-up state. When the auxiliary circuit receives the LP-WUS, the auxiliary circuit can wake up the main circuit, so that the main circuit enters the wake-up state from the sleep state. At this time, the first device is also in a wake-up state.

[0161] Next, in combination with Figure 3 describe the communication method 300 in the embodiments of the present application. As Figure 3 shown, the communication method 300 includes:

[0162] S310, the second device sends the first indication information to the first device, and the first device receives the first indication information from the second device. The first indication information is used to wake up the first device.

[0163] Among them, before the first device receives the first indication information, the first device is in a sleep state.

[0164] Optionally, the second device may be a network device, and the first device is a terminal device. For example, the first indication information may be LP-WUS, which is used to wake up the terminal device, so that the terminal device enters the wake-up state.

[0165] Optionally, the second device may be an auxiliary circuit in the terminal device, and the first device may be a main circuit in the terminal device. The auxiliary circuit may send the first indication information to the main circuit to wake up the main circuit, so that the main circuit can enter the wake-up state from the sleep state. For example, the first indication information may be a pulse signal or the like. Optionally, before the auxiliary circuit sends the first indication information to the main circuit, the auxiliary circuit may receive LP-WUS from the network device. After receiving the LP-WUS, the auxiliary circuit may trigger the auxiliary circuit to send the first indication information to the main circuit.

[0166] S320. The first device sends second indication information to the second device, and the second device receives the second indication information from the first device. The second indication information is used to indicate that the first device has been woken up.

[0167] Optionally, if the second device does not receive the second indication information from the first device, the second device may determine that the first device has not been woken up, and then the second device may not execute S330.

[0168] Optionally, before S320, the first device may enter the wake-up state according to the first indication information. That is to say, when the first device sends the second indication information to the second device, the first device is in the wake-up state.

[0169] Among them, the second device in S310 is a network device. Optionally, if the second device in S310 is a network device and the first device is a terminal device, then in S320, the terminal device sends the second indication information to the network device; if the second device in S310 is an auxiliary circuit in the terminal device and the first device is a main circuit in the terminal device, then in S320, the terminal device also sends the second indication information to the network device. In other words, the first device sends an indication to the network device so that the network device can know that the first device has been woken up.

[0170] Optionally, the first indication information is used to indicate the first time-frequency resource. For example, when the first indication information is LP-WUS, LP-WUS may indicate the first time-frequency resource. S320 includes: the first device sends the second indication information to the second device on the first time-frequency resource. That is to say, LP-WUS can not only be used to wake up the first device but also be used to indicate the first time-frequency resource for reporting the second indication information.

[0171] Optionally, S320 includes: the first device sends second indication information to the second device through a physical uplink shared channel (PUSCH), and the second device receives the second indication information from the first device through the PUSCH. That is to say, the second indication information can be carried in the PUSCH.

[0172] Optionally, S320 includes: the first device sends second indication information to the second device through a physical random access channel (PRACH), and the second device receives the second indication information from the first device through the PRACH. That is to say, the second indication information can be carried in the PRACH.

[0173] Optionally, S320 includes: the first device sends second indication information to the second device through a physical uplink control channel (PUCCH), and the second device receives the second indication information from the first device through the PUCHH. That is to say, the second indication information can be carried in the PUCCH.

[0174] Optionally, S320 includes: the first device sends second indication information to the second device through a physical uplink shared channel (PUSCH), and the second device receives the second indication information from the first device through the PUSCH. That is to say, the second indication information can be carried in the PUSCH. For example, the M bits in the UCI sequence in the PUSCH are used to carry the first sequence corresponding to the second indication information. For example, the UCI sequence is: a0, a1, a2, a3, …, a A-1 , where A = O LPWUS , is the first sequence corresponding to the second indication information, and O LPWUS is the number of bits of the first sequence. If the UCI sequence also includes other sequences (such as HQRA feedback sequences and / or CSI sequences), the first sequence corresponding to the second indication information can be before or after other sequences, and the embodiments of the present application do not limit this.

[0175] Optionally, if the first device sends second indication information to the second device through the PUCCH, the PUCCH may include an uplink control information (UCI) sequence, and the UCI sequence includes the first sequence corresponding to the second indication information, and the first sequence corresponding to the second indication information is carried on the PUCCH. For example, the UCI sequence is: a0, a1, a2, a3, …, aA-1 , where i = 0, 1, ..., O LPWUS -1, A = O LPWUS , is the first sequence corresponding to the second indication information, O LPWUS is the number of bits of the first sequence.

[0176] The following describes several cases. The PUCCH includes the first sequence corresponding to the second indication information.

[0177] Case 1: The first bit position in the PUCCH carrying the hybrid automatic repeat request (HARQ) is used to carry the first sequence. That is, the first bit position in the PUCCH used to carry HARQ can be reused to carry the first sequence. For example, if the value of the first sequence at the first bit position is the first bit value, it means that the first device has been successfully awakened. If the value of the first sequence at the first bit position is the second bit value, it means that the first device has not been awakened. For example, the first bit value is 1 and the second bit value is 0. That is, the first device can reuse the bit position of the HARQ sequence in the PUCCH. In this way, the overhead can be saved.

[0178] Case 2: The second bit position in the PUCCH carrying the scheduling request (SR) is used to carry the first sequence. That is, the first bit position in the PUCCH used to carry SR can be reused to carry the first sequence. For example, if the value of the first sequence at the first bit position is the first bit value, it means that the first device has been successfully awakened. If the value of the first sequence at the first bit position is the second bit value, it means that the first device has not been awakened. For example, the first bit value is 1 and the second bit value is 0. That is, the first device can reuse the bit position of the SR sequence in the PUCCH. In this way, the overhead can be saved.

[0179] Case 3: The UCI sequence included in the PUCCH may also include the HARQ feedback sequence and the first sequence. In the case where the UCI sequence includes the HARQ feedback sequence and the first sequence, the first sequence is located after the HARQ feedback sequence in the UCI sequence, or the HARQ feedback sequence is located after the first sequence in the UCI sequence. That is, in the case where the UCI sequence includes the first sequence corresponding to the second indication information and the HARQ feedback sequence, the positional relationship between the first sequence and the HARQ feedback sequence can be specified by the protocol. For example, it is agreed that the first sequence is before the HARQ feedback sequence. For example, the UCI sequence is: a0, a1, a2, a3, …, a A-1 , where where i = 0, 1, …, OLPWUS -1; and where i = O LPWUS , O LPWUS +1,..., O ACK +O LPWUS -1, A = O LPWUS +O ACK , is the HARQ feedback sequence, O ACK is the number of bits of the HARQ feedback sequence, is the first sequence corresponding to the second indication information, O LPWUS is the number of bits of the first sequence; or it is agreed that the first sequence is after the HARQ feedback sequence, etc. For example, the UCI sequence is: a0, a1, a2, a3,..., a A-1 , where where i = 0, 1,..., O ACK -1; and where i = O ACK , O ACK +1,..., O ACK +O LPWUS -1, A = O LPWUS +O ACK , is the HARQ feedback sequence, O ACK is the number of bits of the HARQ feedback sequence, is the first sequence corresponding to the second indication information, O LPWUS is the number of bits of the first sequence. Optionally, if the priority of the HARQ feedback sequence is the same as that of the first sequence, the protocol can stipulate that the first sequence is before the HARQ feedback sequence, or it can stipulate that the HARQ feedback sequence is before the first sequence. Optionally, the second device can indicate the priority of the first sequence to the first device. For example, the second device can send priority indication information, and the priority indication information is used to indicate the priority of the first sequence. If the first device determines that the priority of the first sequence is the same as that of the HARQ feedback sequence and both are high priorities, the protocol can stipulate that the first sequence is before the HARQ feedback sequence, or it can stipulate that the HARQ feedback sequence is before the first sequence. In other words, when the priorities of these two sequences are the same and both are high priorities, the protocol can stipulate the order of these two sequences.

[0180] Case 4. The UCI sequence included in the PUCCH may include a HARQ feedback sequence, an SR sequence, and a first sequence. In the first possible manner, the first sequence is located after the SR sequence in the UCI sequence, and the HARQ feedback sequence is located before the SR sequence in the UCI sequence. That is, the order of these three sequences is: HARQ feedback sequence, SR sequence, and first sequence. For example, the UCI sequence is: a0, a1, a2, a3, …, a A-1 , where where i = 0, 1, …, O ACK -1; and where i = O ACK , O ACK +1, …, O ACK +O SR -1; and where i = O ACK +O SR , O ACK +O SR +1, …, O ACK +O LPWUS +O SR -1, A = O LPWUS +O ACK +O SR , is the HARQ feedback sequence, O ACK is the number of bits of the HARQ feedback sequence, is the SR sequence, O SR is the number of bits of the SR sequence, is the first sequence corresponding to the second indication information, O LPWUS is the number of bits of the first sequence; In the second possible manner, the first sequence is located before the HARQ feedback sequence in the UCI sequence, and the HARQ feedback sequence is located before the SR sequence in the UCI sequence. That is, the order of these three sequences is: first sequence, HARQ feedback sequence, and SR sequence. For example, the UCI sequence is: a0, a1, a2, a3, …, a A-1 , where where i = 0, 1, …, O LPWUS -1; where i = O LPWUS , O LPWUS +1, …, O LPWUS +O ACK -1; and where i = O ACK +O LPWUS , O ACK +O LPWUS +1, …, O ACK +O LPWUS +OSR -1; A = O LPWUS +O ACK +O SR , is the HARQ feedback sequence, O ACK is the number of bits of the HARQ feedback sequence, is the SR sequence, O SR is the number of bits of the SR sequence, is the first sequence corresponding to the second indication information, O LPWUS is the number of bits of the first sequence; In the third possible way, the HARQ feedback sequence is before the first sequence in the UCI sequence, and the first sequence is before the SR sequence in the UCI sequence. That is to say, the order of these three sequences is: HARQ feedback sequence, first sequence, and SR sequence. For example, the UCI sequence is: a0, a1, a2, a3,..., a A-1 , where, where i = 0, 1,..., O ACK -1; and where i = O ACK , O ACK +1,..., O ACK +O LPWUS -1; and where i = O ACK +O LPWUS , O ACK +O LPWUS +1,..., O ACK +O LPWUS +O SR -1, A = O LPWUS +O ACK +O SR , is the HARQ feedback sequence, O ACK is the number of bits of the HARQ feedback sequence, is the SR sequence, O SR is the number of bits of the SR sequence, is the first sequence corresponding to the second indication information, O LPWUSis the number of bits of the first sequence. The protocol may specify the order of these three sequences in one of the above possible ways. Optionally, if the priority of the SR sequence is the same as that of the first sequence, the protocol may specify that the first sequence is before the SR sequence (e.g., the second possible way or the third possible way), or may specify that the SR sequence is before the first sequence (e.g., the first possible way). Optionally, the second device may indicate the priority of the first sequence to the first device. For example, the second device may send priority indication information, which is used to indicate the priority of the first sequence. If the first device determines that the priority of the first sequence is the same as that of the SR sequence and both are high priorities, the protocol may specify that the first sequence is before the SR sequence, or may specify that the SR sequence is before the first sequence. In other words, when the priorities of these two sequences are the same and both are high priorities, the protocol may specify the order of these two sequences. Among them, the HARQ feedback sequence is before the UCI sequence and the UCI sequence is before the SR sequence.

[0181] Case 5, the UCI sequence included in the PUCCH may include a channel state information (CSI) sequence, and the first sequence is before the CSI sequence in the UCI sequence. For example, the UCI sequence is: a0, a1, a2, a3, …, a A-1 , where, where i = 0, 1, …, O LPWUS -1; and where i = O LPWUS , O LPWUS +1, …, O CSI +O LPWUS -1, A = O LPWUS +O CSI , is the CSI sequence, O CSI is the number of bits of the CSI sequence, is the first sequence corresponding to the second indication information, O LPWUS is the number of bits of the first sequence; or the first sequence is after the CSI sequence in the UCI sequence. For example, the UCI sequence is: a0, a1, a2, a3, …, a A-1 , where, where i = 0, 1, …, O CSI -1; and where i = O CSI , O CSI +1, …, O CSI +O LPWUS -1, A = O LPWUS +O CSI , is the CSI sequence, O CSIis the number of bits of the CSI sequence, is the first sequence corresponding to the second indication information, O LPWUS is the number of bits of the first sequence. That is, in the case where the UCI sequence includes the first sequence corresponding to the second indication information and the CSI sequence, the positional relationship between the first sequence and the CSI sequence can be specified by the protocol. For example, it can be specified that the first sequence is before the CSI sequence, or it can be specified that the first sequence is after the CSI sequence, etc. Optionally, if the priority of the CSI sequence is the same as the priority of the first sequence, the protocol can specify that the first sequence is before the CSI sequence, or it can specify that the CSI sequence is before the first sequence. Optionally, the second device can indicate the priority of the first sequence to the first device. For example, the second device can send priority indication information, and the priority indication information is used to indicate the priority of the first sequence. If the first device determines that the priority of the first sequence is the same as the priority of the CSI sequence and both are high priorities, the protocol can specify that the first sequence is before the CSI sequence, or it can specify that the CSI sequence is before the first sequence. In other words, when the priorities of these two sequences are the same and both are high priorities, the protocol can specify the order of these two sequences.

[0182] Optionally, in Case 5, the CSI sequence can be composed of two parts. The first CSI subsequence and the second CSI subsequence form the CSI sequence. Among them, the UCI sequence can include the first CSI subsequence, the second CSI subsequence, and the first sequence. Among them, the first sequence can be before the first CSI subsequence in the UCI sequence, and the first CSI subsequence is before the second CSI subsequence in the UCI. At this time, the order of these three sequences is: the first sequence, the first CSI subsequence, the second CSI subsequence; or, the first CSI subsequence is before the first sequence in the UCI sequence, and the first sequence is before the second CSI subsequence in the UCI sequence. At this time, the order of the three sequences is: the first CSI subsequence, the first sequence, the second CSI subsequence; or, the first CSI subsequence is before the second CSI subsequence in the UCI sequence, and the second CSI subsequence is before the first sequence. At this time, the order of these three sequences is: the first CSI subsequence, the second CSI subsequence, and the first sequence. That is, when the CSI sequence is composed of two parts, the protocol can specify that the order of the first sequence and these two CSI subsequences is one of the above orders.

[0183] Case 6, the UCI sequence included in PUCCH may include a first sequence, a HARQ feedback sequence, an SR sequence, and a CSI sequence. In the first possible manner, the first sequence is before the HARQ feedback sequence in the UCI sequence, the HARQ feedback sequence is before the SR sequence in the UCI sequence, and the SR sequence is before the CSI sequence in the UCI sequence. That is, when the UCI sequence includes the first sequence, the HARQ feedback sequence, the SR sequence, and the CSI sequence corresponding to the second indication information, the order of these four sequences may be: the first sequence, the HARQ feedback sequence, the SR sequence, and the CSI sequence. For example, the UCI sequence is: a0, a1, a2, a3, …, a A-1 , where where i = 0, 1, …, O LPWUS -1; where i = O LPWUS , O LPWUS +1, …, O ACK +O LPWUS -1; where i = O LPWUS +O ACK , O LPWUS +O ACK +1, …, O ACK +O LPWUS +O SR -1; where i = O LPWUS +O ACK +O SR , O LPWUS +O ACK +O SR +1, …, O CSI +O ACK +O SR +O LPWUS -1; A = O LPWUS +O CSI +O ACK +O SR , is the CSI sequence, O CSI is the number of bits of the CSI sequence, is the first sequence corresponding to the second indication information, O LPWUS is the number of bits of the first sequence, is the HARQ feedback sequence, O ACK is the number of bits of the HARQ feedback sequence, is the SR sequence, O SR is the number of bits of the SR sequence. If a certain sequence is not in the UCI sequence, the number of bits of this sequence is 0. For example, if there is no HARQ feedback sequence, then O ACKis 0, or there is no SR sequence, then O SR is 0, that is, CSI can be mapped to the UCI sequence, that is, CSI can be obtained from the start of the mapping; in the second possible way, the HARQ feedback sequence is before the first sequence in the UCI sequence, the first sequence is before the SR sequence in the UCI sequence, and the SR sequence is before the CSI sequence. That is, when the UCI sequence includes the first sequence corresponding to the second indication information, the HARQ feedback sequence, the SR sequence, and the CSI sequence, the order of these four sequences can be: HARQ feedback sequence, first sequence, SR sequence, and CSI sequence. For example, the UCI sequence is: a0, a1, a2, a3, …, a A-1 , where where i = 0, 1, ..., O ACK -1; where i = O ACK , O ACK +1, …, O ACK +O LPWUS -1; where i = O LPWUS +O ACK , O LPWUS +O ACK +1, …, O ACK +O LPWUS +O SR -1; where i = O LPWUS +O ACK +O SR , O LPWUS +O ACK +O SR +1, …, O CSI +O ACK +O SR +O LPWUS -1; A = O LPWUS +O CSI +O ACK +O SR , is the CSI sequence, O CSI is the number of bits of the CSI sequence, is the first sequence corresponding to the second indication information, O LPWUS is the number of bits of the first sequence, is the HARQ feedback sequence, O ACK is the number of bits of the HARQ feedback sequence, is the SR sequence, O SRis the number of bits of the SR sequence. If a certain sequence is not present in the UCI sequence, the number of bits of that sequence is 0. For example, if there is no HARQ feedback sequence, then O ACK is 0, or if there is no SR sequence, then O SR is 0, that is to say, CSI can be mapped to the UCI sequence, that is to say, CSI can start mapping from In the third possible way, the HARQ feedback sequence is before the SR sequence in the UCI sequence, the SR sequence is before the first sequence in the UCI sequence, and the first sequence is before the CSI sequence in the UCI sequence. That is to say, when the UCI sequence includes the first sequence, the HARQ feedback sequence, the SR sequence, and the CSI sequence corresponding to the second indication information, the order of these four sequences can be: HARQ feedback sequence, SR sequence, first sequence, and CSI sequence. For example, the UCI sequence is: a0, a1, a2, a3, …, a A-1 , where where i = 0, 1, …, O ACK -1; where i = O ACK , O ACK +1, …, O ACK +O SR -1; where i = O SR +O ACK , O SR +O ACK +1, …, O ACK +O LPWUS +O SR -1; where i = O LPWUS +O ACK +O SR , O LPWUS +O ACK +O SR +1, …, O CSI +O ACK +O SR +O LPWUS -1; A = O LPWUS +O CSI +O ACK +O SR , is the CSI sequence, O CSI is the number of bits of the CSI sequence, is the first sequence corresponding to the second indication information, O LPWUS is the number of bits of the first sequence, is the HARQ feedback sequence, O ACKis the number of bits of the HARQ feedback sequence, is the SR sequence, O SR is the number of bits of the SR sequence. If a certain sequence is not present in the UCI sequence, the number of bits of that sequence is 0. For example, if there is no HARQ feedback sequence, then O ACK is 0, or if there is no SR sequence, then O SR is 0, that is to say, that is to say CSI can be mapped to the of the UCI sequence, that is to say CSI can be from start mapping; in the fourth possible implementation, the HARQ feedback sequence is before the SR sequence in the UCI sequence, the SR sequence is before the CSI sequence in the UCI sequence, and the CSI sequence is before the first sequence in the UCI sequence. That is to say, in the case where the UCI sequence includes the first sequence, the HARQ feedback sequence, the SR sequence, and the CSI sequence corresponding to the second indication information, the order of these four sequences can be: HARQ feedback sequence, SR sequence, CSI sequence, and the first sequence. For example, the UCI sequence is: a0, a1, a2, a3, …, a A-1 , where, where i = 0, 1, …, O ACK -1; where i = O ACK , O ACK +1, …, O ACK +O SR -1; where i = O SR +O ACK , O SR +O ACK +1, …, O ACK +O CSI +O SR -1; where i = O CSI +O ACK +O SR , O CSI +O ACK +O SR +1, …, O CSI +O ACK +O SR +O LPWUS -1; A = O LPWUS +O CSI +O ACK +O SR , is the CSI sequence, O CSI is the number of bits of the CSI sequence, is the first sequence corresponding to the second indication information, OLPWUS is the number of bits of the first sequence, is the HARQ feedback sequence, O ACK is the number of bits of the HARQ feedback sequence, is the SR sequence, O SR is the number of bits of the SR sequence. If a certain sequence is not present in the UCI sequence, the number of bits of that sequence is 0. For example, if there is no HARQ feedback sequence, then O ACK is 0, or if there is no SR sequence, then O SR is 0, that is to say, CSI can be mapped to the of the UCI sequence, that is to say, CSI can start mapping from The protocol can specify the order of these four sequences as one of the above possible ways.

[0184] Optionally, if the priority of the HARQ feedback sequence is the same as that of the first sequence, the protocol may specify that the first sequence is before the HARQ feedback sequence (e.g., the first possible way), or may specify that the HARQ feedback sequence is before the first sequence (e.g., the second possible way). Optionally, the second device may indicate the priority of the first sequence to the first device. For example, the second device may send priority indication information for indicating the priority of the first sequence. If the first device determines that the priority of the first sequence is the same as that of the HARQ feedback sequence and both are high priorities, the protocol may specify that the first sequence is before the HARQ feedback sequence, or may specify that the HARQ feedback sequence is before the first sequence. In other words, when the priorities of these two sequences are the same and both are high priorities, the protocol may specify the order of these two sequences. Optionally, if the priority of the SR sequence is the same as that of the first sequence, the protocol may specify that the first sequence is before the SR sequence (e.g., the second possible way), or may specify that the SR sequence is before the first sequence (e.g., the third possible way). Optionally, the second device may indicate the priority of the first sequence to the first device. For example, the second device may send priority indication information for indicating the priority of the first sequence. If the first device determines that the priority of the first sequence is the same as that of the SR sequence and both are high priorities, the protocol may specify that the first sequence is before the SR sequence, or may specify that the SR sequence is before the first sequence. In other words, when the priorities of these two sequences are the same and both are high priorities, the protocol may specify the order of these two sequences. Optionally, if the priority of the CSI sequence is the same as that of the first sequence, the protocol may specify that the first sequence is before the CSI sequence (e.g., the third possible way), or may specify that the CSI sequence is before the first sequence (e.g., the fourth possible way). Optionally, the second device may indicate the priority of the first sequence to the first device. For example, the second device may send priority indication information for indicating the priority of the first sequence. If the first device determines that the priority of the first sequence is the same as that of the CSI sequence and both are high priorities, the protocol may specify that the first sequence is before the CSI sequence, or may specify that the CSI sequence is before the first sequence. In other words, when the priorities of these two sequences are the same and both are high priorities, the protocol may specify the order of these two sequences. Among them, the HARQ feedback sequence is before the SR sequence in the UCI sequence, and the SR sequence is before the CSI sequence in the UCI sequence.

[0185] Optionally, when the priorities of the HARQ feedback sequence, the first sequence, and the SR sequence are all high priorities, the UCI sequence may consist of two parts: and sequences with high priorities is a sequence with low priority, and the high-priority may include a high-priority first sequence, a high-priority SR sequence, and a high-priority HARQ feedback sequence. Therefore, the order of or is or is, wherein, is the high-priority first sequence, is the high-priority HARQ feedback sequence, is the high-priority SR sequence, and the protocol may stipulate that the order of or is or is, Which one of. Optionally, if the priorities of both the SR sequence and the first sequence are low priorities, the UCI sequence may consist of two parts: and is a high-priority sequence, is a low-priority sequence, and the low-priority may include a low-priority first sequence and a low-priority SR sequence. Therefore the order of or is wherein, is the low-priority first sequence, is the low-priority SR sequence, and the protocol may stipulate that the order of or is Which one of.

[0186] Optionally, the CSI sequence may consist of two parts, a first CSI subsequence and a second CSI subsequence that form the CSI sequence. Among them, the UCI sequence may include a first sequence, a HARQ feedback sequence, an SR sequence, a first CSI subsequence, and a second CSI subsequence. Among them, the first sequence is before the HARQ feedback sequence in the UCI sequence, the HARQ feedback sequence is before the SR sequence in the UCI sequence, the SR sequence is before the first CSI subsequence in the UCI sequence, and the first CSI subsequence is before the second CSI subsequence. At this time, the order of these five sequences is: first sequence, HARQ feedback sequence, SR sequence, first CSI subsequence, second CSI subsequence. Optionally, the UCI sequence may consist of two parts: and wherein may correspond to the first sequence, the HARQ feedback sequence, the SR sequence, the first CSI subsequence, may correspond to a second CSI sub - sequence; or, the HARQ feedback sequence is before the first sequence in the UCI sequence, the first sequence is before the SR sequence in the UCI sequence, the SR sequence is before the first CSI sub - sequence in the UCI sequence, the first sequence is before the second CSI sub - sequence in the UCI sequence. At this time, the order of the five sequences is: HARQ feedback sequence, first sequence, SR sequence, first CSI sub - sequence, second CSI sub - sequence. Optionally, the UCI sequence may consist of two parts: and wherein may correspond to the HARQ feedback sequence, the first sequence, the SR sequence, the first CSI sub - sequence, may correspond to the second CSI sub - sequence; or, the HARQ feedback sequence is before the SR sequence in the UCI sequence, the SR sequence is before the first sequence in the UCI sequence, the first sequence is before the first CSI sub - sequence in the UCI sequence, the first CSI sub - sequence is before the second CSI sub - sequence in the UCI sequence. At this time, the order of the five sequences is: HARQ feedback sequence, SR sequence, first sequence, first CSI sub - sequence, second CSI sub - sequence. Optionally, the UCI sequence may consist of two parts: and wherein may correspond to the HARQ feedback sequence, the SR sequence, the first sequence, the first CSI sub - sequence, may correspond to the second CSI sub - sequence; or, the HARQ feedback sequence is before the SR sequence in the UCI sequence, the SR sequence is before the first CSI sub - sequence in the UCI sequence, the first CSI sub - sequence is before the second CSI sub - sequence in the UCI sequence, the second CSI sub - sequence is before the first sequence in the UCI sequence. At this time, the order of the five sequences is: HARQ feedback sequence, SR sequence, first CSI sub - sequence, second CSI sub - sequence, first sequence. Optionally, the UCI sequence may consist of two parts: and wherein may correspond to the HARQ feedback sequence, the SR sequence, the first CSI sub - sequence, may correspond to the second CSI sub - sequence, the first sequence. That is to say, at this time, the first sequence is in the second part of the UCI sequence and after the second CSI sub - sequence. That is to say, when the CSI sequence consists of two parts and the UCI sequence also includes the HARQ feedback sequence, the SR sequence and the first sequence, the protocol may stipulate that the order between the first sequence and these sequences is one of the above orders.

[0187] That is to say, in the above Cases 3 to 6, a first sequence is newly added to the UCI sequence. The position of the first sequence in the UCI sequence can be before or after any one of the HARQ feedback sequence, the SR sequence, or the CSI sequence. Optionally, if the first sequence has the same priority as a certain sequence and both are of high priority, the protocol can specify the order of these two high-priority sequences in the UCI sequence. Optionally, in the above Cases 3 to 6, the length of the UCI sequence is greater than 2.

[0188] Optionally, when the length of the UCI sequence is less than or equal to 2, the first device in S320 can send second indication information to the second device through the PUCCH. The format of the PUCCH is format 0 or format 1. For example, a set value of the cyclic shift of the PUCCH indicates that the PUCCH carries the second indication information.

[0189] Optionally, S320 includes: the first device sends the second indication information at the nearest reporting moment after the first preset time period, and the second device receives the second indication information at the nearest receiving moment after the first preset time period. The second device can determine that the first device has been awakened based on the received second indication information. If the second device does not receive the second indication information at the nearest receiving moment after the first preset time period, it means that the first device has not been awakened; or the first device sends the second indication information at the nearest reporting moment after the first device is awakened within the first preset time period, and the second device receives the second indication information at the nearest receiving moment after the first device is awakened within the first preset time period. The second device can determine that the first device has been awakened based on the received second indication information. If the second device does not receive the second indication information at the nearest reporting moment after the first device is awakened within the first preset time period, it means that the first device has not been awakened. In this way, it is avoided that the first device does not send the second indication information due to timeout, and the second device needs to wait indefinitely for the second indication information, resulting in a waste of resources. Optionally, the first preset time period can correspond to a first timer, and the unit of the duration of the first timer can be SFN, subframe, time slot, symbol, second, or millisecond.

[0190] The following describes several cases of how the first device learns the first preset time period.

[0191] Case 1: The first preset time period is specified by the protocol. For example, the protocol can specify that the time period within the preset duration starting from the moment when the first device receives the first indication information is the first preset time period. The first device can determine the first preset time period based on the moment of receiving the first indication information and the preset duration.

[0192] In Case 2, the first indication information in S310 may indicate a first preset time period. For example, when the first indication information is LP-WUS, LP-WUS can both wake up the first device and indicate the first preset time period.

[0193] In Case 3, the second device may send third indication information, and the first device may receive the third indication information from the second device. The third indication information is used to indicate the first preset time period. That is to say, the second device may send dedicated indication information to indicate the first preset time period. The first device may send the third indication information within the first preset time period, and the second device may receive the third indication information within the first preset time period. If the second device does not receive the third indication information within the first preset time period, the second device may determine that the first device has not been woken up. Optionally, the second device may send a low power synchronization signal (LP-SS), and the first device receives the LP-SS. The LP-SS includes the third indication information. That is to say, the third indication information is carried on the LP-SS. Optionally, the second device may send a system information block (SIB), and the first device may receive the SIB. The SIB may include the third indication information. That is to say, the third indication information is carried on the SIB. Optionally, the second device may send a radio resource control (RRC) message, and the first device may receive the RRC message. The RRC message may include the third indication information. That is to say, the third indication information is carried on the RRC message. Optionally, the second device may send a media access control (MAC) control element (CE), and the first device may receive the MAC CE. The MAC CE includes the third indication information. That is to say, the third indication information is carried on the MAC CE. Optionally, the second device may send downlink control information (DCI), and the first device receives the DCI. The DCI includes the third indication information. That is to say, the third indication information is carried on the DCI. Optionally, the second device may send the third indication information before sending the first indication information.

[0194] Optionally, the first preset time period is greater than the duration for which the first device is awakened. In this way, it is possible to avoid the situation where the time for reporting the second indication information arrives before the first device is awakened, resulting in the inability to report the second indication information. Optionally, the starting moment of the first preset time period is the moment when the first device receives the first indication information. Optionally, the first device sends the second indication information at the nearest reporting moment after the first preset time period, and the second device receives the second indication information at the nearest receiving moment after the first preset time period. Here, the reporting moment and the receiving moment are relative concepts. The reporting moment is described from the perspective of the first device, and the receiving moment is described from the perspective of the second device. For example, as Figure 4 shown, the duration for which the first device is awakened is t ramp-up , the starting moment of the first preset time period is the moment when the first indication information is received, and the first preset time period is greater than t ramp-up , the duration for which the first device is awakened can be preset or determined based on the first device itself. For example, when the first device is the main circuit, t ramp-up is the time required for the auxiliary circuit to awaken the main circuit. For example, when the first device is a terminal device, t ramp-up is the time required for the network device to awaken the terminal device. The first device can report the second indication information at the nearest reporting moment after the first preset time period. Optionally, in some embodiments, the first preset time period determined by the first device is the same as the first preset time period determined by the second device. In other embodiments, the first preset time period determined by the first device is different from the first preset time period determined by the second device. For example, the duration of the first preset time period determined by the second device may be greater than the duration of the first preset time period determined by the first device. When the second device determines the duration of the first preset time period, it may receive the transmission delay of the second indication information and / or the transmission delay of the first indication information. Therefore, the duration of the first preset time period determined by the second device may be greater than the duration of the first preset time period determined by the first device. For example, the first device determines preset time period 1, and the second device determines preset time period 2, and the duration of preset time period 2 is greater than the duration of preset time period 1. In this way, it can be ensured that the second indication information sent by the first device within preset time period 1 can be received by the second device within preset time period 2.

[0195] Optionally, the first preset time period is the sum of the duration when the first device is awakened and the first duration. The first duration is the duration between the first moment when the first device is awakened and the second moment. The second moment is the farthest reporting moment among the multiple consecutive reporting moments closest to the first moment. In this way, the first device can send the second indication information at the closest reporting moment after the first device is awakened within the first preset time period. Specifically, the first device can determine the first moment as the moment when the first device is awakened based on the moment of receiving the first indication information and the duration when the first device is awakened. The first device can determine the multiple consecutive reporting moments closest to the first moment, and the farthest moment among the multiple consecutive reporting moments from the first moment is the second moment. After the second device sends the first indication information, the second device uses the determined moment of sending the first indication information as the starting moment of the first preset time period. The second device determines the first moment when the first device is awakened based on the duration when the first device is awakened at the starting moment, and determines the multiple consecutive receiving moments closest to the first moment. The farthest moment among the multiple consecutive receiving moments from the first moment is the second moment, and the second moment is the ending moment of the first preset time period. The duration of the first preset time period is from the starting moment to the ending moment. In this way, if the second device receives the second indication information at the closest receiving moment after the first device is awakened within the first preset time period, it can determine that the first device has been awakened. If the second device does not receive the second indication information within the first preset time period, it can determine that the first device has not been awakened. For example, as Figure 5 shown, the duration when the first device is awakened is t ramp-up t ramp-up , and the starting moment of the first preset time period is the moment t1 of receiving the first indication information. Then the first moment of awakening the first device is t ramp-up +t1. The two consecutive reporting moments closest to t ramp-up +t1 are t2 and t3. Therefore, the starting moment of the first preset time period is t1, and the ending moment is t3. The closest reporting moment to t ramp-up +t1 within the first preset time period is t2. Therefore, the first device sends the second indication information at the moment t2. The duration t ramp-up when the first device is awakened can be preset or determined by the first device itself. Among them, the reporting moment and the receiving moment are relative concepts. The reporting moment is described from the perspective of the first device, and the receiving moment is described from the perspective of the second device. For example, when the first device is the main circuit, t ramp-up is the time required for the auxiliary circuit to wake up the main circuit. For example, when the first device is a terminal device, t ramp-upThe time required for the network device to wake up the terminal device. Optionally, in some embodiments, the first preset time period determined by the first device is the same as the first preset time period determined by the second device. In other embodiments, the first preset time period determined by the first device is different from the first preset time period determined by the second device. For example, the duration of the first preset time period determined by the second device may be greater than the duration of the first preset time period determined by the first device. When the second device determines the duration of the first preset time period, it may receive the delay of the second indication information and / or the transmission delay of the first indication information. Therefore, the duration of the first preset time period determined by the second device may be greater than the duration of the first preset time period determined by the first device. For example, the first device determines a preset time period 3, and the second device determines a preset time period 4, and the duration of the preset time period 4 is greater than the duration of the preset time period 3. In this way, it can be ensured that the second indication information sent by the first device within the preset time period 3 can be received by the second device within the preset time period 4. Optionally, the second device may configure the reporting time for the first device.

[0196] Optionally, before S320, the second device may send a fourth indication information to the first device, and the first device may receive the fourth indication information from the second device. The fourth indication information is used to indicate that the first device reports that the first device is awakened. That is to say, the second device may indicate to the first device that the first device can report that the first device is awakened. Therefore, when the first device is awakened, the first device may send the second indication information based on the fourth indication information. Optionally, before the second device sends the fourth indication information to the first device, the first device may send a fifth indication information to the second device. The fifth indication information is used to indicate that the first device supports reporting that the first device is awakened, or the fifth indication information is used to indicate that the first device has the ability to report that the first device is awakened. When the first device has this ability, the second device may send the fifth indication information to the first device according to the fourth indication information. When the fifth indication information indicates that the first device does not have the ability to report that the first device is awakened, the second device may not send the fourth indication information to the first device, or the sent fourth indication information indicates that the first device does not need to report that the first device is awakened. Optionally, in some embodiments, the second device may directly send the fourth indication information to the first device without determining whether the first device has the ability to report that the first device is awakened.

[0197] S330, the second device sends a Physical Downlink Control Channel (PDCCH) and / or a Physical Downlink Shared Channel (PDSCH) to the first device, and the first device receives the PDCCH and / or the PDSCH from the second device.

[0198] Optionally, the second device may send a PDCCH and / or a PDSCH to the first device according to the second indication information. That is to say, the second device may know that the first device has been awakened according to the second indication information, and the first device may normally receive the PDCCH and / or the PDSCH because the second device may continue to send the PDCCH and / or the PDSCH. If the second device does not receive the second indication information and cannot know whether the first device has been awakened, the second device does not send the PDCCH nor the PDSCH, which can avoid wasting network resources.

[0199] Optionally, in S330, the second device is a network device and the first device is a terminal device. Optionally, S330 includes: the second device sends a PDCCH to the first device, and the first device receives the PDCCH from the second device. The PDCCH is used to schedule the PDSCH. The second device may send the PDSCH according to the PDCCH, and the first device may receive the PDSCH according to the PDCCH. Or S330 includes: the second device sends a PDSCH to the first device, and the first device receives the PDSCH from the second device.

[0200] Optionally, after S320, if the first device does not receive a PDCCH, or does not receive a PDSCH, or neither receives a PDCCH nor receives a PDSCH within a second preset time period after the first preset time period, the first device may send the second indication information again. That is to say, if the first device does not receive a PDCCH nor receive a PDSCH within the second preset time period, it means that the second device has not received the second indication information, and the first device may try to continue to send the second indication information to avoid the situation that after the first device fails to send the second indication information, the second device cannot know whether the first device has been awakened, resulting in the second device being unable to continue to send the PDCCH and / or the PDSCH. Optionally, the second preset time period may correspond to a second timer, and the unit of the corresponding duration of the second timer may be a system frame number (SFN), a subframe, a time slot, a symbol, a second, or a millisecond. Optionally, the second preset time period may be specified by a protocol or indicated by the second device to the first device. For example, the second device may indicate the second preset time period to the first device in the manner of SIB, RRC, MAC CE, or DCI. Or the first indication information may indicate the second preset time period. For example, when the first indication information is LP-WUS, LP-WUS may wake up the first device and may also indicate the second preset time period. The embodiments of the present application do not impose any restrictions on how the second device indicates the second preset time period to the first device.

[0201] Optionally, the communication method 300 further includes: after a first preset time period, if the first device does not receive a PDCCH, or does not receive a PDSCH, or neither receives a PDCCH nor receives a PDSCH, it indicates that the second device may not have received the second indication information. The first device may resend the second indication information. After the first device has continuously sent the second indication information N times, and the first device still does not receive a PDCCH, or still does not receive a PDSCH, or neither receives a PDCCH nor receives a PDSCH, the first device stops sending the second indication information. N is a positive integer, and the second device may indicate N to the first device. For example, the second device may indicate N to the first device by means of SIB, RRC, MAC CE, or DCI. Alternatively, the first indication information may indicate N. For example, in the case where the first indication information is LP-WUS, LP-WUS may wake up the first device and may also indicate N. The embodiments of the present application do not impose any restrictions on how the second device indicates the second preset time period to the first device. Optionally, after the first device has continuously sent the second indication information N times, and the first device still does not receive a PDCCH, or still does not receive a PDSCH, or neither receives a PDCCH nor receives a PDSCH, the first device stops sending the second indication information, and the first device may continue to enter the sleep state, thereby avoiding the power consumption problem caused by the first device being in the wake-up state all the time.

[0202] Optionally, the second indication information in S320 may be replaced with a wake-up success message, that is, the function of the second indication information is to enable the second device to know that the first device has been woken up. As for the name of the second indication information, the embodiments of the present application do not impose any restrictions.

[0203] In the above communication method 300, after receiving the first indication information, the first device may enter the wake-up state from the sleep state according to the first indication information. After the first device enters the wake-up state, it may send the second indication information so that the second device knows that the first device has entered the wake-up state, and thus the second device may send a PDCCH and / or a PDSCH to the first device; if the second device does not receive the second indication information, the second device may not send a PDCCH and / or a PDSCH, avoiding waste of network resources.

[0204] In the above communication method 300, the second device may send first indication information, and the first device receives the first indication information. If the first device has been awakened according to the first indication information, the first device may send second indication information, and the second device may know that the first device has been awakened according to the second indication information, so as to trigger the second device to send a PDCCH. After the second device sends the PDCCH, it may send a PDSCH scheduled by the PDCCH, which can avoid the problem of resource waste caused by the second device blindly sending a PDCCH because it cannot determine whether the first device has been awakened; in some other embodiments, the second device may send first indication information, and the first device receives the first indication information. The second device may continue to send a PDCCH when sending the first indication information. If the first device receives the PDCCH, it may send a response message of the PDCCH to the second device. If the second device receives the response message of the PDCCH, it means that the first device has been awakened, and the second device may continue to send a PDSCH scheduled by the PDCCH. If the second device does not receive the response message of the PDCCH, it means that the first device has not been awakened, and it will not send a PDSCH scheduled by the PDCCH. In this way, it is possible to avoid the problem of network resource waste caused by the second device blindly sending a PDSCH because it cannot determine whether the first device has been awakened or has received the PDCCH.

[0205] In some embodiments, if the first device does not receive LP-WUS for a long time, the first device may actively enter the wake-up state from the sleep state and may send first indication information to the second device to trigger the second device to send a PDCCH and / or a PDSCH. In this way, it is possible to avoid the situation where the first device cannot be awakened because it cannot receive LP-WUS due to reasons such as being out of coverage, resulting in the problem of inability to transmit.

[0206] The following combines Figure 6 to describe the communication method 600 provided by the embodiments of the present application. The communication method 600 includes:

[0207] S610, the first device enters the sleep state at the first moment.

[0208] Optionally, before S610, the first device is awakened. When the first device does not receive a PDCCH and / or a PDSCH for a long time, in S610, the first device may enter the sleep state, that is, if the first device has no need to transmit data within a preset duration before the first moment, the first device may enter the sleep state.

[0209] Optionally, if the first device is a terminal device, the first device enters the sleep state at the first moment, which can be understood as: the main circuit of the first device enters the sleep state at the first moment, and the auxiliary circuit of the first device remains in the wake state all the time. That is to say, in the communication method 600, when the terminal device enters the sleep state, it can be understood that the main circuit of the terminal device enters the sleep state, and the auxiliary circuit of the terminal device is in the wake state; when the terminal device enters the wake state, it can be understood that the main circuit of the terminal device enters the wake state.

[0210] S620, within a first preset duration after the first moment, if the first device does not receive LP-WUS, the first device enters the wake state from the sleep state.

[0211] Optionally, the first device entering the wake state from the sleep state can be understood as: the first device actively enters the wake state from the sleep state. For example, if the auxiliary receiver of the first device does not receive LP-WUS within a first preset duration after the first moment, the auxiliary receiver of the first device triggers the main receiver of the first device to enter the wake state from the sleep state, so that the first device enters the wake state from the sleep state.

[0212] If the first device does not receive LP-WUS within a first preset duration after the first moment, the first device can actively enter the wake state from the sleep state. For example, if the first device is a terminal device, the auxiliary circuit of the terminal device can wake up the main circuit of the terminal device, and the main circuit of the terminal device enters the wake state. At this time, it means that the terminal device enters the wake state. Optionally, the auxiliary circuit of the terminal device can send a pulse signal to the main circuit of the terminal device to wake up the main circuit of the terminal device.

[0213] Optionally, the unit of the first preset duration is subframe or SFN or time slot or symbol or second or millisecond, etc., and the embodiments of the present application do not limit this.

[0214] Optionally, the first preset duration can be the duration of a first timer, and the first timer can be reset when the first device enters the sleep state from the wake state.

[0215] The following describes several cases of how the first device obtains the first preset duration.

[0216] Case 1, the first preset duration is specified by the protocol. For example, the protocol can specify the first preset duration starting from the first moment when the first device enters the sleep state.

[0217] In Case 2, the second device may send second indication information, and the first device may receive the second indication information from the second device. The second indication information is used to indicate a first preset duration. Optionally, the second device may send LP-SS, and the first device may receive the LP-SS. The LP-SS includes the second indication information, that is, the second indication information is carried in the LP-SS. Optionally, the second device may send SIB, and the first device may receive the SIB. The SIB may include the second indication information, that is, the second indication information is carried in the SIB. Optionally, the second device may send an RRC message, and the first device may receive the RRC message. The RRC message may include the second indication information, that is, the second indication information is carried in the RRC message. Optionally, the second device may send a MAC CE, and the first device may receive the MAC CE. The MAC CE includes the second indication information, that is, the second indication information is carried in the MAC CE. Optionally, the second device may send DCI, and the first device may receive the DCI. The DCI includes the second indication information, that is, the second indication information is carried in the DCI.

[0218] S630. The first device sends first indication information to the second device, and the second device receives the first indication information from the first device. The first indication information is used to trigger the second device to send PDCCH and / or PDSCH.

[0219] If the second device has a need to send PDCCH and / or PDSCH to the first device, then S640 may be executed. If the second device has no need to send PDCCH to the first device and has no need to send PDSCH either, then S640 may not be executed.

[0220] Optionally, the first indication information may indicate that the first device is in a wake-up state. The second device may learn from the first indication information that the first device is in a wake-up state. If the second device has a need to transmit PDCCH and / or PDSCH to the first device, then S640 may be executed.

[0221] Optionally, the first indication information may be CSI. After the second device receives the CSI, it may determine that the first device has the ability to send CSI, which means that the first device is in a wake-up state. Therefore, the CSI may also trigger the second device to send PDCCH and / or PDSCH.

[0222] Optionally, if the first device includes a main circuit and an auxiliary circuit, S630 includes: the main circuit of the first device sends first indication information to the second device, and the second device receives the first indication information from the main circuit of the first device. Among them, the auxiliary circuit of the first device is used to receive LP-WUS and is also used to wake up the main circuit of the first device, but the main circuit of the first device is responsible for receiving PDCCH and / or PDSCH from the second device.

[0223] Optionally, S630 includes: the first device sends first indication information to the second device via PUSCH, and the second device receives the first indication information from the first device via PUSCH. That is to say, the first indication information can be carried in PUSCH.

[0224] Optionally, S630 includes: the first device sends first indication information to the second device via PRACH, and the second device receives the first indication information from the first device via PRACH. That is to say, the first indication information can be carried in PRACH.

[0225] Optionally, S630 includes: the first device sends first indication information to the second device via PUCCH, and the second device receives the first indication information from the first device via PUCCH. That is to say, the first indication information can be carried in PUCCH.

[0226] Optionally, if the first device sends first indication information to the second device via PUCCH, the PUCCH may include a UCI sequence, and the UCI sequence includes a first sequence corresponding to the first indication information, and the first sequence corresponding to the first indication information is carried on the PUCCH.

[0227] The following describes several cases where the PUCCH includes a first sequence corresponding to the first indication information.

[0228] Case 1: The first bit position for carrying HARQ in the PUCCH is used to carry the first sequence. That is to say, the first bit position for carrying HARQ in the PUCCH can be reused to carry the first sequence. For example, if the value of the first sequence at the first bit position is the first bit value, it means that the first device has been successfully awakened; if the value of the first sequence at the first bit position is the second bit value, it means that the first device has not been awakened. For example, the first bit value is 1 and the second bit value is 0. That is to say, the first device can reuse the bit position carrying the HARQ sequence in the PUCCH, so that the overhead can be saved.

[0229] Case 2: The second bit position for carrying SR in the PUCCH is used to carry the first sequence. That is to say, the first bit position for carrying SR in the PUCCH can be reused to carry the first sequence. For example, if the value of the first sequence at the first bit position is the first bit value, it means that the first device has been successfully awakened; if the value of the first sequence at the first bit position is the second bit value, it means that the first device has not been awakened. For example, the first bit value is 1 and the second bit value is 0. That is to say, the first device can reuse the bit position carrying the SR sequence in the PUCCH, so that the overhead can be saved.

[0230] Case 3. The UCI sequence included in the PUCCH may further include a HARQ feedback sequence and a first sequence. When the UCI sequence includes a HARQ feedback sequence and a first sequence, the first sequence is located after the HARQ feedback sequence in the UCI sequence, or the HARQ feedback sequence is located after the first sequence in the UCI sequence. That is to say, when the UCI sequence includes the first sequence corresponding to the second indication information and the HARQ feedback sequence, the positional relationship between the first sequence and the HARQ feedback sequence can be specified by the protocol. For example, it is agreed that the first sequence is before the HARQ feedback sequence, or it is agreed that the first sequence is after the HARQ feedback sequence, etc. Optionally, if the priority of the HARQ feedback sequence is the same as that of the first sequence, the protocol may specify that the first sequence is before the HARQ feedback sequence, or may specify that the HARQ feedback sequence is before the first sequence. Optionally, the second device may indicate the priority of the first sequence to the first device. For example, the second device may send priority indication information, which is used to indicate the priority of the first sequence. If the first device determines that the priority of the first sequence is the same as that of the HARQ feedback sequence and both are high priorities, the protocol may specify that the first sequence is before the HARQ feedback sequence, or may specify that the HARQ feedback sequence is before the first sequence. In other words, when the priorities of these two sequences are the same and both are high priorities, the protocol may specify the order of these two sequences.

[0231] In Case 4, the UCI sequence included in the PUCCH may include a HARQ feedback sequence, an SR sequence, and a first sequence. In the first possible manner, the first sequence is located after the SR sequence in the UCI sequence, and the HARQ feedback sequence is located before the SR sequence in the UCI sequence. That is to say, the order of these three sequences is: HARQ feedback sequence, SR sequence, and first sequence. In the second possible manner, the first sequence is located before the HARQ feedback sequence in the UCI sequence, and the HARQ feedback sequence is located before the SR sequence in the UCI sequence. That is to say, the order of these three sequences is: first sequence, HARQ feedback sequence, and SR sequence. In the third possible manner, the HARQ feedback sequence is located before the first sequence in the UCI sequence, and the first sequence is located before the SR sequence in the UCI sequence. That is to say, the order of these three sequences is: HARQ feedback sequence, first sequence, and SR sequence. The protocol may specify that the order of these three sequences is one of the above possible manners. Optionally, if the priority of the SR sequence is the same as that of the first sequence, the protocol may specify that the first sequence is before the SR sequence (e.g., the second possible manner or the third possible manner), or may specify that the SR sequence is before the first sequence (e.g., the first possible manner). Optionally, the second device may indicate the priority of the first sequence to the first device. For example, the second device may send priority indication information, which is used to indicate the priority of the first sequence. If the first device determines that the priority of the first sequence is the same as that of the SR sequence and both are high priorities, the protocol may specify that the first sequence is before the SR sequence, or may specify that the SR sequence is before the first sequence. In other words, when the priorities of these two sequences are the same and both are high priorities, the protocol may specify the order of these two sequences. Among them, the HARQ feedback sequence is located before the SR sequence in the UCI sequence.

[0232] Case 5. The UCI sequence included in the PUCCH may include a channel state information (CSI) sequence. The first sequence is after the CSI sequence in the UCI sequence, or the first sequence is after the CSI sequence in the UCI sequence. That is to say, when the UCI sequence includes the first sequence corresponding to the second indication information and the CSI sequence, the positional relationship between the first sequence and the CSI sequence can be stipulated by the protocol. For example, it can be stipulated that the first sequence is before the CSI sequence, or it can be stipulated that the first sequence is after the CSI sequence, etc. Optionally, if the priority of the CSI sequence is the same as that of the first sequence, the protocol can stipulate that the first sequence is before the CSI sequence, or it can be stipulated that the CSI sequence is before the first sequence. Optionally, the second device can indicate the priority of the first sequence to the first device. For example, the second device can send priority indication information, which is used to indicate the priority of the first sequence. If the first device determines that the priority of the first sequence is the same as that of the CSI sequence and both are high priorities, the protocol can stipulate that the first sequence is before the CSI sequence, or it can be stipulated that the CSI sequence is before the first sequence. In other words, when the priorities of these two sequences are the same and both are high priorities, the protocol can stipulate the order of these two sequences.

[0233] Optionally, in Case 5, the CSI sequence may be composed of two parts, a first CSI subsequence and a second CSI subsequence, which together form the CSI sequence. Among them, the UCI sequence may include the first CSI subsequence, the second CSI subsequence, and the first sequence. Among them, the first sequence may be before the first CSI subsequence in the UCI sequence, and the first CSI subsequence is before the second CSI subsequence in the UCI. At this time, the order of these three sequences is: the first sequence, the first CSI subsequence, the second CSI subsequence; or, the first CSI subsequence is before the first sequence in the UCI sequence, and the first sequence is before the second CSI subsequence in the UCI sequence. At this time, the order of the three sequences is: the first CSI subsequence, the first sequence, the second CSI subsequence; or, the first CSI subsequence is before the second CSI subsequence in the UCI sequence, and the second CSI subsequence is before the first sequence. At this time, the order of these three sequences is: the first CSI subsequence, the second CSI subsequence, and the first sequence. That is to say, when the CSI sequence is composed of two parts, the protocol can stipulate that the order of the first sequence and these two CSI subsequences is one of the above orders.

[0234] Case 6. The UCI sequence included in the PUCCH may include a first sequence, a HARQ feedback sequence, an SR sequence, and a CSI sequence. In the first possible manner, the first sequence is before the HARQ feedback sequence in the UCI sequence, the HARQ feedback sequence is before the SR sequence in the UCI sequence, and the SR sequence is before the CSI sequence in the UCI sequence. That is to say, when the UCI sequence includes the first sequence, the HARQ feedback sequence, the SR sequence, and the CSI sequence corresponding to the second indication information, the order of these four sequences may be: the first sequence, the HARQ feedback sequence, the SR sequence, and the CSI sequence; In the second possible manner, the HARQ feedback sequence is before the first sequence in the UCI sequence, the first sequence is before the SR sequence in the UCI sequence, and the SR sequence is before the CSI sequence. That is to say, when the UCI sequence includes the first sequence, the HARQ feedback sequence, the SR sequence, and the CSI sequence corresponding to the second indication information, the order of these four sequences may be: the HARQ feedback sequence, the first sequence, the SR sequence, and the CSI sequence; In the third possible manner, the HARQ feedback sequence is before the SR sequence in the UCI sequence, the SR sequence is before the first sequence in the UCI sequence, and the first sequence is before the CSI sequence in the UCI sequence. That is to say, when the UCI sequence includes the first sequence, the HARQ feedback sequence, the SR sequence, and the CSI sequence corresponding to the second indication information, the order of these four sequences may be: the HARQ feedback sequence, the SR sequence, the first sequence, and the CSI sequence; In the fourth possible implementation manner, the HARQ feedback sequence is before the SR sequence in the UCI sequence, the SR sequence is before the CSI sequence in the UCI sequence, and the CSI sequence is before the first sequence in the UCI sequence. That is to say, when the UCI sequence includes the first sequence, the HARQ feedback sequence, the SR sequence, and the CSI sequence corresponding to the second indication information, the order of these four sequences may be: the HARQ feedback sequence, the SR sequence, the CSI sequence, and the first sequence. The protocol may specify that the order of these four sequences is one of the above possible manners. Optionally, if the priority of the HARQ feedback sequence is the same as that of the first sequence, the protocol may specify that the first sequence is before the HARQ feedback sequence (such as the first possible manner), or may specify that the HARQ feedback sequence is before the first sequence (such as the second possible manner).Optionally, the second device may indicate the priority of the first sequence to the first device. For example, the second device may send priority indication information for indicating the priority of the first sequence. If the first device determines that the priority of the first sequence is the same as that of the HARQ feedback sequence and both are high priorities, the protocol may specify that the first sequence is before the HARQ feedback sequence, or may specify that the HARQ feedback sequence is before the first sequence. In other words, when the priorities of these two sequences are the same and both are high priorities, the protocol may specify the order of these two sequences. Optionally, if the priority of the SR sequence is the same as that of the first sequence, the protocol may specify that the first sequence is before the SR sequence (e.g., the second possible way), or may specify that the SR sequence is before the first sequence (e.g., the third possible way). Optionally, the second device may indicate the priority of the first sequence to the first device. For example, the second device may send priority indication information for indicating the priority of the first sequence. If the first device determines that the priority of the first sequence is the same as that of the SR sequence and both are high priorities, the protocol may specify that the first sequence is before the SR sequence, or may specify that the SR sequence is before the first sequence. In other words, when the priorities of these two sequences are the same and both are high priorities, the protocol may specify the order of these two sequences. Optionally, if the priority of the CSI sequence is the same as that of the first sequence, the protocol may specify that the first sequence is before the CSI sequence (e.g., the third possible way), or may specify that the CSI sequence is before the first sequence (e.g., the fourth possible way). Optionally, the second device may indicate the priority of the first sequence to the first device. For example, the second device may send priority indication information for indicating the priority of the first sequence. If the first device determines that the priority of the first sequence is the same as that of the CSI sequence and both are high priorities, the protocol may specify that the first sequence is before the CSI sequence, or may specify that the CSI sequence is before the first sequence. In other words, when the priorities of these two sequences are the same and both are high priorities, the protocol may specify the order of these two sequences. Among them, the HARQ feedback sequence is before the SR sequence in the UCI sequence, and the SR sequence is before the CSI sequence in the UCI sequence.

[0235] Optionally, in Case 6, the CSI sequence may consist of two parts. The first CSI subsequence and the second CSI subsequence form the CSI sequence. The UCI sequence may include a first sequence, a HARQ feedback sequence, an SR sequence, a first CSI subsequence, and a second CSI subsequence. Among them, the first sequence is before the HARQ feedback sequence in the UCI sequence, the HARQ feedback sequence is before the SR sequence in the UCI sequence, the SR sequence is before the first CSI subsequence in the UCI sequence, and the first CSI subsequence is before the second CSI subsequence. At this time, the order of these five sequences is: the first sequence, the HARQ feedback sequence, the SR sequence, the first CSI subsequence, the second CSI subsequence; or, the HARQ feedback sequence is before the first sequence in the UCI sequence, the first sequence is before the SR sequence in the UCI sequence, the SR sequence is before the first CSI subsequence in the UCI sequence, and the first sequence is before the second CSI subsequence in the UCI sequence. At this time, the order of the five sequences is: the HARQ feedback sequence, the first sequence, the SR sequence, the first CSI subsequence, the second CSI subsequence; or, the HARQ feedback sequence is before the SR sequence in the UCI sequence, the SR sequence is before the first sequence in the UCI sequence, the first sequence is before the first CSI subsequence in the UCI sequence, and the first CSI subsequence is before the second CSI subsequence in the UCI sequence. At this time, the order of the five sequences is: the HARQ feedback sequence, the SR sequence, the first sequence, the first CSI subsequence, the second CSI subsequence; or, the HARQ feedback sequence is before the SR sequence in the UCI sequence, the SR sequence is before the first CSI subsequence in the UCI sequence, the first CSI subsequence is before the first sequence in the UCI sequence, and the first sequence is before the second CSI subsequence in the UCI sequence. At this time, the order of the five sequences is: the HARQ feedback sequence, the SR sequence, the first CSI subsequence, the first sequence, the second CSI subsequence; or, the HARQ feedback sequence is before the SR sequence in the UCI sequence, the SR sequence is before the first CSI subsequence in the UCI sequence, the first CSI subsequence is before the second CSI subsequence in the UCI sequence, and the second CSI subsequence is before the first sequence in the UCI sequence. At this time, the order of the five sequences is: the HARQ feedback sequence, the SR sequence, the first CSI subsequence, the second CSI subsequence, the first sequence. That is to say, when the CSI sequence consists of two parts and the UCI sequence also includes the HARQ feedback sequence, the SR sequence, and the first sequence, the protocol may stipulate that the order between the first sequence and these sequences is one of the above orders.

[0236] That is to say, in the above Cases 3 to 6, a first sequence is added to the UCI sequence, and the position of the first sequence in the UCI sequence can be before or after any one of the HARQ feedback sequence, the SR sequence, or the CSI sequence. Optionally, if the first sequence has the same priority as a certain sequence and both are of high priority, the protocol can specify the order of these two high-priority sequences in the UCI sequence. Optionally, in the above Cases 3 to 6, the length of the UCI sequence is greater than 2.

[0237] Specifically, the formulaic description of the positional relationship of the first sequence in the UCI sequence in the above Cases 3 to 6 can be referred to the description of Method 300, and will not be described in detail to avoid redundancy.

[0238] Optionally, when the length of the UCI sequence is less than or equal to 2, in S630, the first device can send the first indication information to the second device through the PUCCH, and the format of the PUCCH is format 0 or format 1. For example, a set cyclic shift value of the PUCCH indicates that the PUCCH carries the second indication information.

[0239] Optionally, in S630, the first device can send the first indication information on the time-frequency resources indicated by the second device.

[0240] S640, the second device sends the PDCCH and / or PDSCH to the first device, and the first device receives the PDCCH and / or PDSCH from the second device.

[0241] Optionally, the second device can determine that the first device is in the wake-up state according to the first indication information. If the second device needs to send the PDCCH and / or PDSCH to the first device, the second device sends the PDCCH and / or PDSCH to the first device. That is to say, the second device can know that the first device has been woken up according to the first indication information, and the first device can normally receive the PDCCH and / or PDSCH, because the second device can continue to send the PDCCH and / or PDSCH; if the second device does not receive the first indication information and cannot know whether the first device has been woken up, therefore, the second device does not send the PDCCH nor the PDSCH, which can avoid wasting network resources. For example, the first indication information is used to indicate that the first device is in the wake-up state.

[0242] Optionally, in S640, the second device is a network device and the first device is a terminal device. Optionally, S640 includes: the second device sends a PDCCH to the first device, and the first device receives the PDCCH from the second device. The PDCCH is used to schedule the PDSCH. The second device may send the PDSCH according to the PDCCH, and the first device may receive the PDSCH according to the PDCCH. Or S640 includes: the second device sends the PDSCH to the first device, and the first device receives the PDSCH from the second device.

[0243] In the above solution, the first device is in a sleep state starting from the first moment. If the first device does not receive the LP-WUS sent by the second device within the first preset duration starting from the first moment, the first device can actively enter the wake-up state from the sleep state and send a first indication message to the second device to trigger the second device to send a PDCCH and / or a PDSCH to the first device, avoiding the situation where the first device cannot be woken up because it cannot receive the LP-WUS sent by the second device for a long time due to reasons such as exceeding the coverage range when the second device needs to wake up the first device, which is beneficial to improving the transmission performance.

[0244] It should be noted that in communication method 300 and communication method 600, the same nouns may have different meanings. For example, the first indication message, the second indication message, etc. have different meanings in these two communication methods.

[0245] In some cases, if the second device does not receive a response from the first device after sending the LP-WUS, the second device may send the LP-WUS without limit, which will cause waste of signaling. Therefore, in some embodiments, when the number of consecutive LP-WUS transmissions by the second device is greater than or equal to a preset number, the second device may stop sending the LP-WUS, which can avoid the waste problem caused by the second device sending the LP-WUS without limit. Optionally, the preset value can be a pre-specified value. This embodiment can be combined with communication method 600. When the second device attempts to wake up the first device, it can send the LP-WUS. When the number of consecutive transmissions is greater than or equal to the preset number, the second device stops sending the LP-WUS. When the first device does not receive the LP-WUS for a long time, the first device can actively enter the wake-up state so that the second device can know that the first device is in the wake-up state, avoiding the situation where the second device keeps sending the LP-WUS but the first device never receives the LP-WUS, resulting in the first device being unable to enter the wake-up state.

[0246] In some embodiments, the first device may send first auxiliary information to the second device, and the second device may perform low-power related configuration on the first device according to the first auxiliary information. The following is combined with Figure 7Describe the communication method 700 in the embodiments of the present application, as Figure 7 shown, the communication method 700 includes:

[0247] S710, the first device sends first auxiliary information to the second device, and the second device receives the first auxiliary information from the first device, where the first auxiliary information is auxiliary information related to low power consumption.

[0248] Optionally, the first auxiliary information is used to indicate the latency requirement of the first device.

[0249] Optionally, the first auxiliary information is used to indicate that the first device has the ability to report that the first device is in the wake-up state.

[0250] Optionally, the first auxiliary information is used to indicate that the first device expects to enter the second sleep state.

[0251] Optionally, the first auxiliary information is used to indicate the communication quality requirement of the first device.

[0252] Optionally, the first auxiliary information is used to indicate the second measurement period expected by the first device.

[0253] Optionally, the first auxiliary information is used to indicate at least one of the latency requirement of the first device, the ability of the first device to report that the first device is in the wake-up state, the first device's expectation to enter the second sleep state, the communication quality requirement of the first device, or the second measurement period expected by the first device.

[0254] Optionally, if the first device includes a main circuit and an auxiliary circuit, in S710, the main circuit of the first device may send the first auxiliary information to the second device, that is, in S710, the first device may be in the wake-up state.

[0255] Optionally, S710 includes: the first device sends the first auxiliary information to the second device through PUSCH, and the second device receives the first auxiliary information from the first device through PUSCH. That is, the first auxiliary information may be carried in PUSCH.

[0256] Optionally, S710 includes: the first device sends the first auxiliary information to the second device through PRACH, and the second device receives the first auxiliary information from the first device through PRACH. That is, the first auxiliary information may be carried in PRACH.

[0257] Optionally, S710 includes: the first device sends the first auxiliary information to the second device through PUCCH, and the second device receives the first auxiliary information from the first device through PUCCH. That is, the first auxiliary information may be carried in PUCCH.

[0258] Optionally, if the first device sends the first auxiliary information to the second device via PUCCH, the PUCCH may include a UCI sequence, and the UCI sequence includes a first sequence corresponding to the first auxiliary information, and the first sequence corresponding to the first auxiliary information is carried on the PUCCH.

[0259] The following describes several cases where the PUCCH includes a first sequence corresponding to the first auxiliary information.

[0260] Case 1: The first bit position for carrying HARQ in the PUCCH is used to carry the first sequence. That is, the first bit position for carrying HARQ in the PUCCH can be reused to carry the first sequence. For example, if the value of the first sequence in the first bit position is the first bit value, it means that the first device has been successfully awakened. If the value of the first sequence in the first bit position is the second bit value, it means that the first device has not been awakened. For example, the first bit value is 1 and the second bit value is 0. That is, the first device can reuse the bit position carrying the HARQ sequence in the PUCCH, so that the overhead can be saved.

[0261] Case 2: The second bit position for carrying SR in the PUCCH is used to carry the first sequence. That is, the first bit position for carrying SR in the PUCCH can be reused to carry the first sequence. For example, if the value of the first sequence in the first bit position is the first bit value, it means that the first device has been successfully awakened. If the value of the first sequence in the first bit position is the second bit value, it means that the first device has not been awakened. For example, the first bit value is 1 and the second bit value is 0. That is, the first device can reuse the bit position carrying the SR sequence in the PUCCH, so that the overhead can be saved.

[0262] In Case 3, the UCI sequence included in the PUCCH may further include a HARQ feedback sequence and a first sequence. When the UCI sequence includes a HARQ feedback sequence and a first sequence, the first sequence is located after the HARQ feedback sequence in the UCI sequence, or the HARQ feedback sequence is located after the first sequence in the UCI sequence. That is to say, when the UCI sequence includes the first sequence corresponding to the second indication information and the HARQ feedback sequence, the positional relationship between the first sequence and the HARQ feedback sequence can be specified by the protocol. For example, it is agreed that the first sequence is before the HARQ feedback sequence, or it is agreed that the first sequence is after the HARQ feedback sequence, etc. Optionally, if the priority of the HARQ feedback sequence is the same as that of the first sequence, the protocol may specify that the first sequence is before the HARQ feedback sequence, or may specify that the HARQ feedback sequence is before the first sequence. Optionally, the second device may indicate the priority of the first sequence to the first device. For example, the second device may send priority indication information, which is used to indicate the priority of the first sequence. If the first device determines that the priority of the first sequence is the same as that of the HARQ feedback sequence and both are high priorities, the protocol may specify that the first sequence is before the HARQ feedback sequence, or may specify that the HARQ feedback sequence is before the first sequence. In other words, when the priorities of these two sequences are the same and both are high priorities, the protocol may specify the order of these two sequences.

[0263] Case 4. The UCI sequence included in the PUCCH may include a HARQ feedback sequence, an SR sequence, and a first sequence. In the first possible manner, the first sequence is located after the SR sequence in the UCI sequence, and the HARQ feedback sequence is located before the SR sequence in the UCI sequence. That is to say, the order of these three sequences is: HARQ feedback sequence, SR sequence, and first sequence. In the second possible manner, the first sequence is located before the HARQ feedback sequence in the UCI sequence, and the HARQ feedback sequence is located before the SR sequence in the UCI sequence. That is to say, the order of these three sequences is: first sequence, HARQ feedback sequence, and SR sequence. In the third possible manner, the HARQ feedback sequence is located before the first sequence in the UCI sequence, and the first sequence is located before the SR sequence in the UCI sequence. That is to say, the order of these three sequences is: HARQ feedback sequence, first sequence, and SR sequence. The protocol may specify that the order of these three sequences is one of the above possible manners. Optionally, if the priority of the SR sequence is the same as that of the first sequence, the protocol may specify that the first sequence is before the SR sequence (e.g., the second possible manner or the third possible manner), or may specify that the SR sequence is before the first sequence (e.g., the first possible manner). Optionally, the second device may indicate the priority of the first sequence to the first device. For example, the second device may send priority indication information, which is used to indicate the priority of the first sequence. If the first device determines that the priority of the first sequence is the same as that of the SR sequence and both are high priorities, the protocol may specify that the first sequence is before the SR sequence, or may specify that the SR sequence is before the first sequence. In other words, when the priorities of these two sequences are the same and both are high priorities, the protocol may specify the order of these two sequences. Among them, the HARQ feedback sequence is located before the SR sequence in the UCI sequence.

[0264] Case 5. The UCI sequence included in the PUCCH may include a CSI sequence. The first sequence is after the CSI sequence in the UCI sequence, or the first sequence is after the CSI sequence in the UCI sequence. That is to say, when the UCI sequence includes the first sequence corresponding to the second indication information and the CSI sequence, the positional relationship between the first sequence and the CSI sequence can be specified by the protocol. For example, it can be specified that the first sequence is before the CSI sequence, or it can be specified that the first sequence is after the CSI sequence, etc. Optionally, if the priority of the CSI sequence is the same as that of the first sequence, the protocol can specify that the first sequence is before the CSI sequence, or it can specify that the CSI sequence is before the first sequence. Optionally, the second device may indicate the priority of the first sequence to the first device. For example, the second device may send priority indication information, which is used to indicate the priority of the first sequence. If the first device determines that the priority of the first sequence is the same as that of the CSI sequence and both are high priorities, the protocol can specify that the first sequence is before the CSI sequence, or it can specify that the CSI sequence is before the first sequence. In other words, when the priorities of these two sequences are the same and both are high priorities, the protocol can specify the order of these two sequences.

[0265] Optionally, in Case 5, the CSI sequence may be composed of two parts, the first CSI subsequence and the second CSI subsequence form the CSI sequence. Among them, the UCI sequence may include the first CSI subsequence, the second CSI subsequence and the first sequence. Among them, the first sequence may be before the first CSI subsequence in the UCI sequence, and the first CSI subsequence is before the second CSI subsequence in the UCI. At this time, the order of these three sequences is: the first sequence, the first CSI subsequence, the second CSI subsequence; or, the first CSI subsequence is before the first sequence in the UCI sequence, and the first sequence is before the second CSI subsequence in the UCI sequence. At this time, the order of the three sequences is: the first CSI subsequence, the first sequence, the second CSI subsequence; or, the first CSI subsequence is before the second CSI subsequence in the UCI sequence, and the second CSI subsequence is before the first sequence. At this time, the order of these three sequences is: the first CSI subsequence, the second CSI subsequence and the first sequence. That is to say, when the CSI sequence is composed of two parts, the protocol can specify that the order of the first sequence and these two CSI subsequences is one of the above orders.

[0266] Case 6. The UCI sequence included in the PUCCH may include a first sequence, a HARQ feedback sequence, an SR sequence, and a CSI sequence. In the first possible manner, the first sequence is before the HARQ feedback sequence in the UCI sequence, the HARQ feedback sequence is before the SR sequence in the UCI sequence, and the SR sequence is before the CSI sequence in the UCI sequence. That is to say, when the UCI sequence includes the first sequence, the HARQ feedback sequence, the SR sequence, and the CSI sequence corresponding to the second indication information, the order of these four sequences may be: the first sequence, the HARQ feedback sequence, the SR sequence, and the CSI sequence; in the second possible manner, the HARQ feedback sequence is before the first sequence in the UCI sequence, the first sequence is before the SR sequence in the UCI sequence, and the SR sequence is before the CSI sequence. That is to say, when the UCI sequence includes the first sequence, the HARQ feedback sequence, the SR sequence, and the CSI sequence corresponding to the second indication information, the order of these four sequences may be: the HARQ feedback sequence, the first sequence, the SR sequence, and the CSI sequence; in the third possible manner, the HARQ feedback sequence is before the SR sequence in the UCI sequence, the SR sequence is before the first sequence in the UCI sequence, and the first sequence is before the CSI sequence in the UCI sequence. That is to say, when the UCI sequence includes the first sequence, the HARQ feedback sequence, the SR sequence, and the CSI sequence corresponding to the second indication information, the order of these four sequences may be: the HARQ feedback sequence, the SR sequence, the first sequence, and the CSI sequence; in the fourth possible implementation manner, the HARQ feedback sequence is before the SR sequence in the UCI sequence, the SR sequence is before the CSI sequence in the UCI sequence, and the CSI sequence is before the first sequence in the UCI sequence. That is to say, when the UCI sequence includes the first sequence, the HARQ feedback sequence, the SR sequence, and the CSI sequence corresponding to the second indication information, the order of these four sequences may be: the HARQ feedback sequence, the SR sequence, the CSI sequence, and the first sequence. The protocol may specify that the order of these four sequences is one of the above possible manners. Optionally, if the priority of the HARQ feedback sequence is the same as that of the first sequence, the protocol may specify that the first sequence is before the HARQ feedback sequence (such as the first possible manner), or may specify that the HARQ feedback sequence is before the first sequence (such as the second possible manner).Optionally, the second device may indicate the priority of the first sequence to the first device. For example, the second device may send priority indication information for indicating the priority of the first sequence. If the first device determines that the priority of the first sequence is the same as that of the HARQ feedback sequence and both are high priorities, the protocol may specify that the first sequence is before the HARQ feedback sequence, or may specify that the HARQ feedback sequence is before the first sequence. In other words, when the priorities of these two sequences are the same and both are high priorities, the protocol may specify the order of these two sequences. Optionally, if the priority of the SR sequence is the same as that of the first sequence, the protocol may specify that the first sequence is before the SR sequence (e.g., the second possible way), or may specify that the SR sequence is before the first sequence (e.g., the third possible way). Optionally, the second device may indicate the priority of the first sequence to the first device. For example, the second device may send priority indication information for indicating the priority of the first sequence. If the first device determines that the priority of the first sequence is the same as that of the SR sequence and both are high priorities, the protocol may specify that the first sequence is before the SR sequence, or may specify that the SR sequence is before the first sequence. In other words, when the priorities of these two sequences are the same and both are high priorities, the protocol may specify the order of these two sequences. Optionally, if the priority of the CSI sequence is the same as that of the first sequence, the protocol may specify that the first sequence is before the CSI sequence (e.g., the third possible way), or may specify that the CSI sequence is before the first sequence (e.g., the fourth possible way). Optionally, the second device may indicate the priority of the first sequence to the first device. For example, the second device may send priority indication information for indicating the priority of the first sequence. If the first device determines that the priority of the first sequence is the same as that of the CSI sequence and both are high priorities, the protocol may specify that the first sequence is before the CSI sequence, or may specify that the CSI sequence is before the first sequence. In other words, when the priorities of these two sequences are the same and both are high priorities, the protocol may specify the order of these two sequences. Among them, the HARQ feedback sequence is before the SR sequence in the UCI sequence, and the SR sequence is before the CSI sequence in the UCI sequence.

[0267] Optionally, in Case 6, the CSI sequence may consist of two parts. The first CSI subsequence and the second CSI subsequence constitute the CSI sequence. Among them, the UCI sequence may include the first sequence, the HARQ feedback sequence, the SR sequence, the first CSI subsequence, and the second CSI subsequence. Among them, the first sequence is before the HARQ feedback sequence in the UCI sequence, the HARQ feedback sequence is before the SR sequence in the UCI sequence, the SR sequence is before the first CSI subsequence in the UCI sequence, and the first CSI subsequence is before the second CSI subsequence. At this time, the order of these five sequences is: the first sequence, the HARQ feedback sequence, the SR sequence, the first CSI subsequence, the second CSI subsequence; or, the HARQ feedback sequence is before the first sequence in the UCI sequence, the first sequence is before the SR sequence in the UCI sequence, the SR sequence is before the first CSI subsequence in the UCI sequence, and the first sequence is before the second CSI subsequence in the UCI sequence. At this time, the order of the five sequences is: the HARQ feedback sequence, the first sequence, the SR sequence, the first CSI subsequence, the second CSI subsequence; or, the HARQ feedback sequence is before the SR sequence in the UCI sequence, the SR sequence is before the first sequence in the UCI sequence, the first sequence is before the first CSI subsequence in the UCI sequence, and the first CSI subsequence is before the second CSI subsequence in the UCI sequence. At this time, the order of the five sequences is: the HARQ feedback sequence, the SR sequence, the first sequence, the first CSI subsequence, the second CSI subsequence; or, the HARQ feedback sequence is before the SR sequence in the UCI sequence, the SR sequence is before the first CSI subsequence in the UCI sequence, the first CSI subsequence is before the first sequence in the UCI sequence, and the first sequence is before the second CSI subsequence in the UCI sequence. At this time, the order of the five sequences is: the HARQ feedback sequence, the SR sequence, the first CSI subsequence, the first sequence, the second CSI subsequence; or, the HARQ feedback sequence is before the SR sequence in the UCI sequence, the SR sequence is before the first CSI subsequence in the UCI sequence, the first CSI subsequence is before the second CSI subsequence in the UCI sequence, and the second CSI subsequence is before the first sequence in the UCI sequence. At this time, the order of the five sequences is: the HARQ feedback sequence, the SR sequence, the first CSI subsequence, the second CSI subsequence, the first sequence. That is to say, when the CSI sequence consists of two parts and the UCI sequence also includes the HARQ feedback sequence, the SR sequence, and the first sequence, the protocol may stipulate that the order between the first sequence and these sequences is one of the above orders.

[0268] That is to say, in the above Cases 3 to 6, a first sequence is newly added to the UCI sequence, and the position of the first sequence in the UCI sequence can be before or after any one of the HARQ feedback sequence, the SR sequence, or the CSI sequence. Optionally, if the first sequence has the same priority as a certain sequence and both are of high priority, the protocol can stipulate the order of these two high-priority sequences in the UCI sequence.

[0269] Specifically, the formulaic description of the positional relationship of the first sequence in the UCI sequence in the above Cases 3 to 6 can be referred to the description of Method 300, and will not be described in detail to avoid redundancy.

[0270] S720, the second device may send first configuration information to the first device, and the first device may receive the first configuration information from the second device, where the first configuration information is configuration information related to low power consumption.

[0271] Optionally, the first device may communicate according to the first configuration information.

[0272] Optionally, the first device is a terminal device, and the second device is a network device.

[0273] Optionally, S720 includes: the second device sends the first configuration information to the first device according to the first auxiliary information, and the first device may receive the first configuration information sent by the second device according to the first auxiliary information from the second device. Optionally, in S720, the second device may send the first configuration information to the first device according to its own implementation, or may not send the first configuration information according to the first auxiliary information.

[0274] Optionally, if the first auxiliary information indicates the latency requirement of the first device, the second device may send the first configuration information to the first device according to the latency requirement of the first device. For example, if the latency requirement of the first device is less than the preset latency requirement, the first configuration information may configure the first device to report that the first device is in the wake-up state. That is to say, since it takes time for the first device to report that it is in the wake-up state, when the latency requirement of the first device is low, the first device may report that it is in the wake-up state. At this time, if the first device is in the wake-up state, the first device may send the first indication information to the second device according to the first configuration information. The first indication information is used to indicate that the first device is in the wake-up state. After receiving the first indication information, the second device may send PDCCH and / or PDSCH to the first device, and the first device may receive PDCCH and / or PDSCH from the second device. For another example, the second device may select the first sleep state that meets the latency requirement from at least one sleep state according to the latency requirement of the first device, and the first configuration information sent to the first device is used to configure the first device to enter the first sleep state. The first device enters the first sleep state according to the first configuration information. When the latency required for the first device to enter the wake-up state from the first sleep state meets the latency requirement. For example, the at least one sleep state includes: micro sleep, light sleep, or deep sleep.

[0275] Optionally, if the first auxiliary information indicates that the first device has the ability to report that the first device is in the wake-up state, the first configuration information sent by the second device may instruct the first device to report that the first device is in the wake-up state. After the first device enters the wake-up state from the sleep state, the first device may send the first indication information, and the first indication information is used to indicate that the first device is in the wake-up state.

[0276] Optionally, if the first auxiliary information indicates that the first device expects to enter the second sleep state, the second device may configure the first device to enter the second sleep state according to the second sleep state expected by the first device. At this time, the first configuration information may indicate that the first device enters the second sleep state. When the first device has no need to transmit information for a long time, it may enter the second sleep state from the wake state according to the first configuration information. For example, the second sleep state is one of micro sleep, light sleep, or deep sleep; or, the second device may adjust the second sleep state expected by the first device to configure the first device to enter the third sleep state, etc. At this time, the first configuration information may indicate that the first device enters the third sleep state. When the first device has no need to transmit information for a long time, it may enter the third sleep state from the wake state according to the first configuration information. For example, the third sleep state is one of micro sleep, light sleep, or deep sleep.

[0277] Optionally, if the first auxiliary information is used to indicate the communication quality requirement of the first device, the second device may determine a measurement period according to the communication quality requirement, and the first configuration information may indicate the first measurement period. For example, if the communication quality requirement of the first device is high, the time interval of the first measurement period may be smaller; if the communication quality requirement of the first device is low, the time of the first measurement period may be larger. The first device performs radio resource management (RRM) measurements according to the first measurement period, which can meet the communication quality requirement.

[0278] Optionally, if the first auxiliary information is used to indicate the second measurement period expected by the first device, the second device may configure the second measurement period for the first device according to the second measurement period expected by the first device. At this time, the first configuration information may indicate the second measurement period of the first device, and the first device may perform RRM measurements according to the second measurement period; or, the second device may adjust the second measurement period expected by the first device to configure the first device to enter the third measurement period, etc. At this time, the first configuration information may indicate the third measurement period of the first device, and the first device may perform RRM measurements according to the third measurement period.

[0279] Optionally, S720 includes: The second device may send an LP-SS, and the first device may receive the LP-SS. The LP-SS includes first configuration information, that is, the first configuration information is carried on the LP-SS. Optionally, the second device may send an SIB, and the first device may receive the SIB. The SIB may include first configuration information, that is, the first configuration information is carried on the SIB. Optionally, the second device may send an RRC message, and the first device may receive the RRC message. The RRC message may include first configuration information, that is, the first configuration information is carried on the RRC message. Optionally, the second device may send a MAC CE, and the first device may receive the MAC CE. The MAC CE includes first configuration information, that is, the first configuration information is carried on the MAC CE. Optionally, the second device may send DCI, and the first device receives the DCI. The DCI includes first configuration information, that is, the first configuration information is carried on the DCI.
