Description

[0001] This application is a divisional application. The application number of the original application is 201980100587.4, and the original application date is November 8, 2019. The entire contents of the original application are incorporated into this application by reference. Technical Field

[0002] The present application relates to the field of mobile communication technology, and in particular to a communication method, device and equipment. Background Art

[0003] In order to reduce the power consumption of the terminal device, the period of the physical downlink control channel (PDCCH) can be configured for the terminal device in the radio resource control (RRC) connected state, and the terminal device detects the PDCCH according to the configured period.

[0004] However, the base station may have multiple working states, such as normal working state or sleep state, etc. The base station sends PDCCH at different frequencies in different states. However, at present, terminal devices generally only detect PDCCH according to one cycle, which obviously cannot correspond to the different states of the base station and may increase the power consumption of the terminal device. Summary of the invention

[0005] Embodiments of the present application provide a communication method, apparatus, and device for reducing power consumption of terminal equipment.

[0006] In a first aspect, a first communication method is provided, the method comprising: determining a first signaling, the first signaling being used to indicate at least one period, each period of the at least one period being a period for a terminal device to detect a downlink signal; and sending the first signaling.

[0007] The method may be performed by a first communication device, which may be a communication device or a communication device capable of supporting the communication device to implement the functions required by the method, such as a chip. Exemplarily, the first communication device is a network device, or a chip provided in the network device for implementing the functions of the network device, or other components for implementing the functions of the network device. In the following introduction, the first communication device is taken as an example that the network device is an example.

[0008] In an embodiment of the present application, the network device can indicate at least one cycle to the terminal device, so that the terminal device can detect the downlink signal according to the at least one cycle. For example, at least one cycle matches the state of the network device, which is equivalent to the terminal device detecting the downlink signal according to the state of the network device, thereby minimizing the power consumption of the terminal device.

[0009] In an optional implementation, the at least one cycle matches at least one sleep mode.

[0010] A cycle matches a sleep mode, for example, a matching method is that the difference between the length of the cycle and the sleep granularity of the sleep mode is less than a first threshold. The first threshold is, for example, configured by the network device, or specified by a protocol. If the first threshold is 0, the length of the cycle is equal to the sleep granularity of the sleep mode. When the cycle matches the sleep mode of the network device, the terminal device can also detect the downlink signal according to the matching cycle when the network device is in sleep mode, and try to avoid the terminal device still detecting the downlink signal according to the cycle when the network device is in an active state when the network device is in sleep mode, thereby reducing the probability of the terminal device doing useless work and reducing the power consumption of the terminal device. Moreover, the cycle and the sleep mode of the network device may correspond. If the network device may be in multiple sleep modes in sequence, the number of at least one cycle may be greater than 1, that is, the network device may indicate multiple cycles to the terminal device. When the network device is in a sleep mode, the terminal device can detect the downlink signal according to the cycle matching the sleep mode, so that the cycle of the terminal device can match each sleep mode of the network device, thereby reducing the power consumption of the terminal device.

[0011] In an optional implementation, the first signaling is further used to indicate the number of times the terminal device performs detection in the at least one period.

[0012] For one or more cycles in at least one cycle, the terminal device may execute once, or may execute multiple times. For example, for a sleep mode, if the network device repeatedly executes the sleep mode, if the cycle corresponds to the sleep mode, the cycle of the terminal device will be repeated accordingly, or the terminal device will also repeatedly detect the downlink signal accordingly. Therefore, the first signaling can indicate the number of times the terminal device detects in at least one cycle, or other signaling can be used to indicate the number of times the detection is performed in at least one cycle. By indicating the number of detections, the cycle of the terminal device and the sleep mode of the network device are more accurately matched. For the sleep mode, if the network device repeats the execution multiple times, then the number can be called the number of repetitions of the sleep mode, or the number of cycles of the sleep mode, etc. Here, the number of times the terminal device detects in a cycle refers to the interval between two adjacent detections satisfying the cycle, or the number of times the terminal device executes the cycle, rather than the number of times the terminal device detects the downlink signal within the cycle.

[0013] In an optional implementation, the first signaling is further used to indicate the order in which the terminal devices perform detection in the at least one period.

[0014] If the number of at least one cycle is greater than 1, then the terminal device will have a corresponding order when detecting according to at least one cycle, or when the terminal device executes the at least one cycle. Optionally, if the number of at least one cycle is greater than 1, the first signaling can also indicate the order of at least one cycle, or in other words, indicate the order in which the terminal device detects with at least one cycle. Alternatively, the order of at least one cycle can also be indicated by other signaling. This is equivalent to indicating the order of at least one cycle in an explicit manner. If at least one cycle matches at least one sleep mode, then the order of at least one cycle and the order of the corresponding at least one sleep mode can be the same, so that the terminal device can detect the downlink signal according to the cycle that matches the sleep mode of the network device.

[0015] In an optional implementation, the first signaling is further used to indicate one or more offsets, and the one or more offsets are used for auxiliary period detection.

[0016] For at least one cycle, one or more offsets may correspond, and the number of offsets corresponding to at least one cycle may be equal to or unequal to the number of at least one cycle. In addition to indicating at least one cycle to the terminal device, the network device may also indicate one or more offsets corresponding to at least one cycle to the terminal device, and the one or more offsets may assist the terminal device in detection. For example, the cycle corresponds to the sleep mode, and the sleep mode corresponds to a deactivation time and an activation time. Through the offset, the cycle can correspond to the sleep granularity of the sleep mode, while the deactivation time and activation time corresponding to the sleep mode may not necessarily correspond to the cycle. In this way, the cycle determined by the terminal device is more matched with the sleep mode of the network device.

[0017] Alternatively, if the offset corresponding to at least one cycle is very short and can be ignored, the network device may not need to indicate the offset of at least one cycle. For example, some manufacturers' hardware devices have better performance, so that the deactivation time when the network device enters a sleep mode is short, and the activation time when exiting a sleep mode is also short, which does not affect the terminal device's detection of downlink signals, so the network device may not need to indicate the offset of at least one cycle.

[0018] In an optional embodiment, the method further includes:

[0019] When the number of detections of the at least one cycle ends, a second signaling is sent, where the second signaling is used to indicate a first cycle, and the first cycle is located after the at least one cycle in sequence.

[0020] If the terminal device needs to execute multiple cycles in sequence, and the first signaling only indicates the next part of the cycle to be executed, the network device can also send a second signaling to the terminal device. For example, the terminal device can receive the second signaling when or before the execution of at least one cycle is completed. The second signaling can indicate one or more cycles, and the one or more cycles are located after the at least one cycle in sequence. For example, the second signaling can indicate the first cycle, and the first cycle can be a cycle included in the one or more cycles. For example, the network device will enter multiple sleep modes in sequence, and the first signaling only indicates the cycle corresponding to the next part of the sleep mode to be entered. Then, when the network device wakes up from at least one sleep mode, it can send the second signaling again, and the second signaling can indicate the first cycle corresponding to the next sleep mode located after the at least one sleep mode. Optionally, the second signaling can also indicate the number of times the terminal device detects in the first cycle. Optionally, the second signaling can also indicate the offset of the first cycle. Similarly, the second signaling can be a unicast signaling, a multicast signaling, or a broadcast signaling. For the implementation of the second signaling, reference can be made to the introduction of the first signaling.

[0021] In this way, the network device can indicate different periods through different signaling, thereby reducing the amount of information included in the signaling. Moreover, for example, the network device can determine the period to be indicated before indicating the corresponding period each time, without having to determine all the periods at once, so that the period determined by the network device is more in line with the current situation.

[0022] In an optional implementation manner, the first signaling is used to indicate at least one period, including:

[0023] The first signaling includes the at least one period; or,

[0024] The first signaling includes an identifier of the first cycle set, where the identifier of the first cycle set is used to indicate the at least one cycle, the first cycle set is one of multiple cycle sets, and each cycle set in the multiple cycle sets includes a sequential combination of one or more cycles.

[0025] For example, a network device may obtain multiple cycle sets, and each cycle set in the multiple cycle sets may include one cycle, or include a sequential combination of multiple cycles. For example, a network device may set multiple cycle sets by itself, or multiple cycle sets may also be specified by a protocol. Then, if the network device wants to determine at least one cycle, it may directly determine a cycle set from the multiple cycle sets. Determining the cycle set means determining at least one cycle. For example, if the network device determines a first cycle set, the first cycle set may correspond to at least one cycle, or in other words, the first cycle set may correspond to a sequential combination of at least one cycle.

[0026] If the network device has configured multiple cycle sets for the terminal device in advance, or multiple cycle sets are pre-configured in the terminal device, or multiple cycle sets are specified by the protocol, the first signaling may include an identifier of the first cycle set, which can reduce the signaling overhead; or, if the terminal device has not been configured with multiple cycle sets in advance, or the network device has not determined the first cycle set, or although the network device has determined the first cycle set but has not configured multiple cycle sets for the terminal device in advance, the first signaling may still include at least one cycle, which can prevent the terminal device from having to perceive the cycle set, thereby simplifying the implementation of the terminal device.

[0027] In an optional embodiment, the method further includes:

[0028] A third signaling is sent, where the third signaling is used to indicate the multiple period sets.

[0029] If the network device configures multiple period sets to the terminal device, for example, the network device may send a third signaling, and the third signaling is used to indicate the multiple period sets. After the terminal device receives the third signaling from the network device, the multiple period sets can be determined. The third signaling may be a unicast signaling, a multicast signaling, or a broadcast signaling, and is not specifically limited.

[0030] In an optional embodiment, in the at least one cycle, the length of the preceding cycle is greater than the length of the succeeding cycle.

[0031] For example, the cycle corresponds to the sleep mode, so the network device can determine the corresponding cycle according to the sleep mode. For example, the network device can determine the order of at least one sleep mode according to the power consumption corresponding to the network device. For example, in at least one sleep mode, the power consumption of the network device when it is in the sleep mode that comes first is less than the power consumption of the network device when it is in the sleep mode that comes later. For example, the at least one sleep mode determined by the network device is sleep mode 1, sleep mode 2, and sleep mode 3. The power consumption of the network device when it is in sleep mode 1 is power consumption 1, the power consumption when it is in sleep mode 2 is power consumption 2, and the power consumption when it is in sleep mode 3 is power consumption 3, and power consumption 1> power consumption 2> power consumption 3. Then, the order of the three sleep modes determined by the network device can be sleep mode 3-sleep mode 2-sleep mode 1, which can be referred to. Figure 4B . Then, the order of at least one corresponding cycle can be: the cycle corresponding to sleep mode 3 - the cycle corresponding to sleep mode 2 - the cycle corresponding to sleep mode 1. This is equivalent to the network device performing a "deep to shallow" sleep. The network device performs sleep in this "deep to shallow" manner, which is the most energy-efficient sleep mode. Then, correspondingly, if the power consumption of the network device when in sleep mode 1 is greater than the power consumption of the network device when in sleep mode 2, the length of the cycle corresponding to sleep mode 1 is less than the length of the cycle corresponding to sleep mode 2. Therefore, the length of the cycle in the previous order is greater than the length of the cycle in the later order.

[0032] In an optional implementation manner, the first signaling is used to indicate at least one period, including:

[0033] The first signaling indicates a first duration, where the first duration is related to one of the at least one period.

[0034] For example, when the number of at least one period is 1, the first signaling may indicate the first duration. At this time, one of the at least one period refers to this one period. Then, the first duration being related to one of the at least one period means that the first duration is related to this period. For example, the first duration is the total duration for the terminal device to perform detection at the period corresponding to the first duration. For example, if the period matches the sleep mode, then the first duration may be the total duration that the network device is in the sleep mode. When the network device is in the sleep mode, the terminal device performs detection at the period corresponding to the first duration. Therefore, the first duration can also be considered as the total duration for the terminal device to perform detection at this period. The terminal device can determine the corresponding period according to the first duration, making the way for the terminal device to determine the period more flexible. Moreover, if the first duration is the total duration that the network device is in the sleep mode and the terminal device selects the corresponding period, then the terminal device can determine the number of detections for this period based on the first duration and the length of this period. Therefore, if the first signaling indicates the first duration, the first signaling does not have to indicate the number of detections for this period, which can reduce the amount of information indicated by the first signaling and save signaling overhead.

[0035] In an alternative embodiment, the first duration being related to one of the at least one period includes:

[0036] The value of the first duration is proportional to the value of the one period.

[0037] For example, the value of the first duration can be proportional to the value of the period. For example, the at least one threshold may include two thresholds Th1 and Th2, where Th1 < Th2. Let X and Y be two positive numbers. If the value of the first duration is X, the corresponding period is period A. If the value of the first duration is Y, the corresponding period is period B. If X is less than Y, then A is less than B. For example, if 0 < X < Th1 and Th1 ≤ Y < Th2, that is, X < Y, then A is less than B, which means that the value of the first duration can be proportional to the value of the one period.

[0038] For example, if the first duration is the total duration that the network device is in the sleep mode, then the longer the network device is in the sleep mode, the longer the duration of the first period can be, so that the period of the terminal device can match the sleep mode of the network device.

[0039] In an alternative embodiment, the method further includes:

[0040] After waking up, send a fourth signaling, where the fourth signaling is a WUS signaling, or a DCI for scheduling data, or a signaling for carrying special information.

[0041] For example, when the network device is in sleep mode, it will wake up if it receives downlink service; or, after executing at least one sleep mode, the network device will wake up regardless of whether it receives downlink service. After waking up, the network device can send the fourth signaling to the terminal device to communicate normally with the terminal device.

[0042] In an optional implementation, the first signaling is RRC signaling, DCI, or system message.

[0043] The embodiment of the present application does not limit the implementation method of the first signaling.

[0044] In an optional embodiment, the at least one period is used to change the period of the first search space of the terminal device to the at least one period, the first search space is the search space for sending the first signaling, or the first search space includes any one of all search spaces supported by the terminal device.

[0045] Before the terminal device replaces the period of the search space of the terminal device according to at least one period, the original period of the search space may be configured by the network device through RRC signaling. It can be seen that in the embodiment of the present application, although the first signaling may be RRC signaling or may not be RRC signaling, no matter what type of signaling the first signaling is, the terminal device can replace the original period configured by the network device through RRC signaling according to at least one period indicated by the first signaling. In this sense, at least one period can be used to change the period of the first search space of the terminal device to at least one period, the first search space is the search space for sending the first signaling, or the first search space includes any one of all search spaces supported by the terminal device.

[0046] In a second aspect, a second communication method is provided, the method comprising: receiving a first signaling from a network device, the first signaling being used to indicate at least one period, each period of the at least one period being a period for a terminal device to detect a downlink signal; and detecting the downlink signal according to the at least one period.

[0047] The method may be performed by a second communication device, which may be a communication device or a communication device capable of supporting the communication device to implement the functions required by the method, such as a chip. Exemplarily, the second communication device is a terminal device, or a chip provided in the terminal device for implementing the functions of the terminal device, or other components for implementing the functions of the terminal device. In the following introduction, the second communication device is taken as an example of a terminal device.

[0048] In an optional implementation, the at least one cycle matches at least one sleep mode.

[0049] In an optional implementation, the first signaling is further used to indicate the number of times the terminal device performs detection in the at least one period.

[0050] In an optional implementation, the first signaling is further used to indicate the order in which the terminal devices perform detection in the at least one period.

[0051] In an optional implementation, the first signaling is further used to indicate one or more offsets, and the one or more offsets are used for auxiliary period detection.

[0052] In an optional embodiment, the method further includes:

[0053] A second signaling is received from the network device, where the second signaling is used to indicate a first cycle, and the first cycle is located after the at least one cycle in sequence.

[0054] In an optional implementation manner, the first signaling is used to indicate at least one period, including:

[0055] The first signaling includes the at least one period; or,

[0056] The first signaling includes an identifier of the first cycle set, where the identifier of the first cycle set is used to indicate the at least one cycle, the first cycle set is one of multiple cycle sets, and each cycle set in the multiple cycle sets includes a sequential combination of one or more cycles.

[0057] In an optional embodiment, the method further includes:

[0058] A third signaling is received from the network device, where the third signaling is used to indicate the multiple period sets.

[0059] In an optional embodiment, in the at least one cycle, the length of the preceding cycle is greater than the length of the succeeding cycle.

[0060] In an optional implementation manner, the first signaling is used to indicate at least one period, including:

[0061] The first signaling indicates a first duration, where the first duration is related to one of at least one period.

[0062] In an optional implementation, the first duration is related to one of at least one cycle, including:

[0063] The value of the first duration is proportional to the value of the period.

[0064] In an optional embodiment, the method further includes:

[0065] receiving a fourth signaling from the network device, where the fourth signaling is a WUS signaling, or a DCI for scheduling data, or a signaling for carrying special information;

[0066] The downlink signal is detected according to a second period, where the second period does not belong to the at least one period.

[0067] In an optional implementation, the first signaling is RRC signaling, DCI, or system message.

[0068] In an optional embodiment, the at least one period is used to change the period of the first search space of the terminal device to the at least one period, the first search space is the search space for sending the first signaling, or the first search space includes any one of all search spaces supported by the terminal device.

[0069] In an optional implementation, detecting the downlink signal according to a third period in the at least one period includes:

[0070] Determine that a period of a first search space is less than or equal to the third period, and the first search space is a search space to be executed for the third period;

[0071] A downlink signal is detected in the first search space according to the third period.

[0072] In an optional implementation, detecting the downlink signal according to a third period in the at least one period includes:

[0073] Determine that a period of a first search space is greater than the third period, and the first search space is a search space to be executed for the third period;

[0074] In the first search space, the downlink signal is detected according to the third period, or, in the first search space, the downlink signal is detected according to an M×P period, where M is a positive integer and P is the length of the second period.

[0075] If the period of the first search space is less than or equal to the third period, the terminal device may replace the period of the first search space with the third period, and the terminal device may detect the downlink signal in the first search space according to the third period. Alternatively, if the period of the first search space is greater than the third period, the terminal device may replace the period of the first search space with M times the third period, that is, the terminal device may detect the PDCCH in the first search space according to the period of M×P, where P represents the length of the third period and M is a positive integer. The value of M×P may be made as close as possible to the length of the original period of the first search space, so that the change to the period of the first search space is small, which is more conducive to the implementation of the terminal device. Alternatively, if the period of the first search space is greater than the third period, the terminal device may replace the period of the first search space with the third period, or the terminal device may set the period of the first search space to the least common multiple of the original period of the first search space and the third period. The terminal device may determine whether to modify the period of the first search space based on the judgment result, so that the modification of the period of the search space by the terminal device may be more reasonable.

[0076] In an optional implementation, the first search space is a search space for receiving the first signaling, or the first search space includes any one of all search spaces supported by the terminal device.

[0077] That is to say, the terminal device may only make a judgment on the second search space, and for other search spaces supported by the terminal device except the second search space, the terminal device does not apply at least one period to these search spaces, that is to say, for other search spaces supported by the terminal device except the second search space, the terminal device continues to use the original period of these search spaces to detect downlink signals; or, the terminal device may make a judgment on each search space among all the search spaces supported by the terminal device, and the terminal device may detect downlink signals according to the third period in each search space among all the supported search spaces. The second search space refers to the search space for receiving the first signaling.

[0078] Regarding the technical effects of the second aspect or various implementations, reference may be made to the introduction to the technical effects of the first aspect or corresponding implementations.

[0079] According to a third aspect, a third communication method is provided, which includes: determining a first signaling, wherein the first signaling is used to indicate the number of times a terminal device performs detection in a first cycle, or to indicate a first duration of time for the terminal device to perform detection in the first cycle, wherein the first cycle is a cycle for the terminal device to detect downlink signals; and sending the first signaling.

[0080] The method may be performed by a third communication device, which may be a communication device or a communication device capable of supporting the communication device to implement the functions required by the method, such as a chip. Exemplarily, the third communication device is a network device, or a chip provided in the network device for implementing the functions of the network device, or other components for implementing the functions of the network device. In the following introduction, the third communication device is taken as an example that the network device is an example.

[0081] In an embodiment of the present application, the network device can indicate the first cycle to the terminal device, so that the terminal device can detect the downlink signal according to the first cycle. For example, the first cycle matches the state of the network device, which is equivalent to the terminal device detecting the downlink signal according to the state of the network device, thereby minimizing the power consumption of the terminal device.

[0082] In an optional implementation, the first cycle matches a sleep mode.

[0083] In an embodiment of the present application, the first cycle can be matched with the sleep mode, so that the terminal device can detect the downlink signal according to the first cycle, which is equivalent to the terminal device can detect the downlink signal according to the sleep mode of the network device, and try to avoid the terminal device detecting the downlink signal according to the cycle when the network device is in an activated state when the network device is in sleep mode, thereby reducing the probability of the terminal device doing useless work and reducing the power consumption of the terminal device.

[0084] In an optional implementation, the first signaling is further used to indicate an offset, and the offset is used to assist in period detection.

[0085] For the first period, it may correspond to one or more offsets. In addition to indicating the first period to the terminal device, the network device may also indicate one or more offsets corresponding to the first period to the terminal device, and the one or more offsets may assist the terminal device in detection. For example, the period corresponds to the sleep mode, and the sleep mode corresponds to a deactivation time and an activation time. Through the offset, the period can correspond to the sleep granularity of the sleep mode, while the deactivation time and activation time corresponding to the sleep mode may not necessarily correspond to the period. In this way, the period determined by the terminal device is more compatible with the sleep mode of the network device.

[0086] Alternatively, if the offset corresponding to the first cycle is very short and can be ignored, the network device may not need to indicate the offset of at least one cycle. For example, some manufacturers' hardware devices have better performance, so that the deactivation time of the network device when entering a sleep mode is shorter, and the activation time when exiting a sleep mode is also shorter, which does not affect the terminal device to detect the downlink signal, so the network device does not need to indicate the offset of the first cycle.

[0087] In an optional embodiment, the method further includes:

[0088] After waking up, a second signaling is sent, where the second signaling is WUS signaling, or DCI for scheduling data, or signaling for carrying special information.

[0089] For example, when the network device is in sleep mode, it will wake up if it receives downlink service; or, after executing at least one sleep mode, the network device will wake up regardless of whether it receives downlink service. After waking up, the network device can send the fourth signaling to the terminal device to communicate normally with the terminal device.

[0090] In an optional implementation, the first signaling is RRC signaling, DCI, or system message.

[0091] The embodiment of the present application does not limit the implementation method of the first signaling.

[0092] In a fourth aspect, a fourth communication method is provided, which includes: receiving a first signaling from a network device, wherein the first signaling is used to indicate the number of times a terminal device performs detection in a first cycle, or to indicate a first duration of time for the terminal device to perform detection in the first cycle, wherein the first cycle is a cycle for the terminal device to detect a downlink signal; and detecting the downlink signal according to the first cycle.

[0093] The method may be performed by a fourth communication device, which may be a communication device or a communication device capable of supporting the communication device to implement the functions required by the method, such as a chip. Exemplarily, the fourth communication device is a terminal device, or a chip provided in the terminal device for implementing the functions of the terminal device, or other components for implementing the functions of the terminal device. In the following introduction, the fourth communication device is taken as an example of a terminal device.

[0094] In an optional implementation, the first cycle matches a sleep mode.

[0095] In an optional implementation, the first signaling is used to indicate the first duration, and the method further includes:

[0096] The number of times detection is performed in the first cycle is determined according to the first time length and the first cycle.

[0097] If the first signaling indicates the first duration, since the terminal device can determine the first period, the terminal device can also determine the first number according to the first duration and the first period. After determining the first number, the terminal device can detect the downlink signal according to the first period and / or the first number.

[0098] In an optional implementation, the first signaling is further used to indicate an offset, and the offset is used to assist in period detection.

[0099] In an optional embodiment, the method further includes:

[0100] A second signaling is received from the network device, where the second signaling is WUS signaling, or DCI for scheduling data, or signaling for carrying special information.

[0101] In an optional implementation, the first signaling is RRC signaling, DCI, or system message.

[0102] In an optional implementation, detecting a downlink signal according to the first cycle includes:

[0103] Determine that a period of a first search space is less than or equal to the first period, and the first search space is a search space to be executed for the first period;

[0104] A downlink signal is detected in the first search space according to the first period.

[0105] In an optional implementation, detecting a downlink signal according to the first cycle includes:

[0106] Determine that a period of a first search space is greater than the first period, and the first search space is a search space to be executed for the first period;

[0107] In the first search space, the downlink signal is detected according to the first period, or, in the first search space, the downlink signal is detected according to an M×P period, where M is a positive integer and P is the length of the first period.

[0108] If the period of the first search space is less than or equal to the first period, the terminal device may replace the period of the first search space with the first period, and the terminal device may detect the downlink signal in the first search space according to the first period. Alternatively, if the period of the first search space is greater than the first period, the terminal device may replace the period of the first search space with M times the first period, that is, the terminal device may detect the PDCCH in the first search space according to the period of M×P, where P represents the length of the first period and M is a positive integer. The value of M×P may be made as close as possible to the length of the original period of the first search space, so that the change to the period of the first search space is small, which is more conducive to the implementation of the terminal device. Alternatively, if the period of the first search space is greater than the first period, the terminal device may replace the period of the first search space with the first period, or the terminal device may set the period of the first search space to the least common multiple of the original period of the first search space and the first period. The terminal device may determine whether to modify the period of the first search space based on the judgment result, so that the modification of the period of the search space by the terminal device may be more reasonable.

[0109] In an optional implementation, the first search space is a search space for receiving the first signaling, or the first search space includes any one of all search spaces supported by the terminal device.

[0110] That is to say, the terminal device can only make a judgment on the second search space, and for other search spaces supported by the terminal device except the second search space, the terminal device does not apply the first period to these search spaces, that is to say, for other search spaces supported by the terminal device except the second search space, the terminal device continues to use the original period of these search spaces to detect downlink signals; or, the terminal device can make a judgment on each search space in all the search spaces supported by the terminal device, and the terminal device can detect downlink signals according to the first period in each search space in all the supported search spaces. The second search space refers to the search space for receiving the first signaling.

[0223] As an example but not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable devices may also be referred to as wearable smart devices or smart wearable devices, etc., which are a general term for the application of wearable technology to intelligently design and develop wearable devices for daily wear, such as glasses, gloves, watches, clothing and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also powerful functions achieved through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-size, and independent of smartphones to achieve complete or partial functions, such as smart watches or smart glasses, etc., as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various types of smart bracelets, smart helmets, and smart jewelry for vital sign monitoring.

[0224] The various terminal devices introduced above, if located on a vehicle (eg, placed in or installed in a vehicle), can be considered as vehicle-mounted terminal devices, which are also called on-board units (OBU).

[0225] In the embodiments of the present application, it can also be understood that anything that can communicate data with a base station can be regarded as a terminal device.

[0226] 2) Network equipment, for example, including access network (AN) equipment, such as base stations (e.g., access points), which can refer to equipment in the access network that communicates with wireless terminal devices over the air interface through one or more cells, or, for example, a network device in a V2X technology is a road side unit (RSU). The base station can be used to convert received air frames to and from IP packets, acting as a router between the terminal device and the rest of the access network, where the rest of the access network may include an IP network. The RSU can be a fixed infrastructure entity that supports V2X applications and can exchange messages with other entities that support V2X applications. The network equipment can also coordinate the attribute management of the air interface. For example, the network device may include an evolved base station (NodeB or eNB or e-NodeB, evolutional Node B) in a long term evolution (LTE) system or long term evolution-advanced (LTE-A), or may also include a next generation node B (next generation node B, gNB) in a fifth generation mobile communication technology (the 5th generation, 5G) new radio (new radio, NR) system (also referred to as an NR system) or may also include a centralized unit (CU) and a distributed unit (DU) in a cloud access network (Cloud RAN) system, but the embodiments of the present application are not limited.

[0227] 3) Downlink control channel, such as PDCCH, or enhanced physical downlink control channel (EPDCCH), or may also include other downlink control channels. No specific limitation is made. The embodiment of the present application mainly takes the downlink control channel as PDCCH as an example.

[0228] 4) Period, or detection period, etc. In order to reduce the power consumption of the terminal device, the period of the downlink signal can be configured for the terminal device in the RRC connected state, and the terminal device detects the downlink signal according to the configured period.

[0229] 5) The downlink signal detected by the terminal device may include, for example, a control signal, or a data signal, or a control signal and a data signal. The control signal may be, for example, a PDCCH.

[0230] 6) The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "At least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can represent: a, b, c, ab, ac, bc, or abc, where a, b, c can be single or multiple.

[0231] Furthermore, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, timing, priority or importance of multiple objects. For example, the first signaling and the second signaling are only used to distinguish different signalings, and do not indicate the difference in the content, sending order, priority or importance of the two signalings.

[0232] The foregoing introduces some terminology concepts involved in the embodiments of the present application. The following introduces the technical features involved in the embodiments of the present application.

[0233] The base station can reduce power consumption by entering sleep mode. Since different devices take different amounts of time to shut down and wake up, the base station can deactivate the devices to varying degrees. Accordingly, the base station can have one or more sleep modes. Each sleep mode may correspond to parameters such as sleep granularity, sleep power consumption, and wake-up time. The values ​​of the parameters corresponding to different sleep modes are completely different or not exactly the same. Generally speaking, the lower the sleep power consumption of a sleep mode and the longer the sleep granularity, the longer the wake-up time. Sleep granularity refers to the sleep duration corresponding to the sleep mode.

[0234] Table 1 shows the sleep granularity and wake-up time corresponding to the three sleep modes. The wake-up time can be the activation time in Table 1. The deactivation time of a sleep mode refers to the time required for the base station to enter the sleep mode from the activated state. The activation time of a sleep mode refers to the time required for the base station to enter the activated state from the sleep mode.

[0235] Table 1

[0236] Sleep Mode Deactivation time Sleep granularity Activation time Sleep Mode 1 35.5μs 71μs 35.5μs Sleep Mode 2 0.5ms 1ms 0.5ms Sleep Mode 3 5ms 10ms 5ms

[0237] Of course, Table 1 is only an example. For example, in Table 1, for a sleep mode, the deactivation time and activation time are equal, but in practice, this is not limited to this. The deactivation time and activation time of some sleep modes may not be equal. In addition, in Table 1, the deactivation time and activation time are both equal to half of the sleep granularity, but in practice, this is not limited to this. For example, the deactivation time or activation time of some sleep modes is 1 / 4 of the sleep granularity, or the deactivation time and activation time are very small relative to the sleep granularity and can be ignored.

[0238] You can refer to it again Figure 1 , is a schematic diagram of a base station using the three sleep modes shown in Table 1 to sleep, specifically, Figure 1 This describes the process of a base station going from an active state to different sleep modes in sequence and then being awakened again. Figure 1 It can be seen that the sleep modes entered by the base station are sleep mode 3, sleep mode 2 and sleep mode 1 in sequence, and the sleep granularities corresponding to these three sleep modes are T3, T2 and T1 respectively. Figure 1 In the sleep mode, the first sleep mode that the base station enters is the sleep mode 3 with the lowest power consumption. Before fully entering the sleep mode 3, it needs to go through the deactivation process of the sleep mode 3, that is, Figure 1 The process represented by the first slash from left to right in the figure shows that the deactivation time and activation time of sleep mode 3 are the longest among the three sleep modes. After the end of sleep mode 3, the base station will switch to sleep mode 2. The switching process before switching to sleep mode 2 is Figure 1 The process shown by the second oblique line from left to right in the figure is related to the activation time of sleep mode 3 and / or the deactivation time of sleep mode 2 and / or the deactivation time of sleep mode 3 and / or the activation time of sleep mode 2. The power consumption level, deactivation time and activation time of the base station corresponding to sleep mode 2 are between sleep mode 3 and sleep mode 1. After the end of sleep mode 2, the base station undergoes a switching process from sleep mode 2 to sleep mode 1, that is, Figure 1 The process represented by the third slash from left to right in the figure can switch to sleep mode 1. The switching process is related to the activation time of sleep mode 2 and / or the deactivation time of sleep mode 1 and / or the deactivation time of sleep mode 2 and / or the activation time of sleep mode 1. The power consumption of the base station corresponding to sleep mode 1 is the largest, but the required activation time is the shortest. After the end of sleep mode 1, the base station undergoes the activation process of sleep mode 1, that is, Figure 1 The process represented by the fourth slash from left to right in the figure can exit sleep mode 1 and return to the active state.

[0239] In addition, in order to reduce the power consumption of the terminal device, the PDCCH period can be configured for the terminal device in the RRC connected state, and the terminal device detects the PDCCH according to the configured period.

[0240] For example, for each search space, the following parameters need to be configured for the terminal device to detect PDCCH: search space set index, control resource set (CORESET) index, period, slot offset, symbol position, number of slots, number of candidate PDCCHs corresponding to each aggregation level, and search space set type. Among them, the CORESET index is the index of the CORESET associated with the search space set, and the CORESET associated with the search space set determines the physical resources of the search space set; the period is the time interval for detecting the search space set, in slots; the slot offset is the slot offset from the start of the period to the actual detection of the search space set, and the offset is less than the length of the period; the symbol position is the position of the CORESET start symbol associated with the search space set in each slot, and the two adjacent symbol positions are greater than or equal to the number of time domain symbols included in the CORESET; the number of slots is the number of slots for continuous detection of the search space set, and the number of slots is less than the number of slots corresponding to the period.

[0241] At present, when the base station enters the sleep mode, the PDCCH period is generally not reconfigured for the terminal device. The terminal device will continue to detect the PDCCH according to the period when the base station is in the activated state. This will obviously increase the power consumption of the terminal device and reduce the efficiency of the terminal device in doing useful work.

[0242] In view of this, a technical solution of an embodiment of the present application is provided. In an embodiment of the present application, a network device can indicate at least one cycle to a terminal device, so that the terminal device can detect a downlink signal according to at least one cycle. For example, at least one cycle matches the state of the network device, which is equivalent to the terminal device detecting the downlink signal according to the state of the network device, thereby reducing the power consumption of the terminal device as much as possible. Moreover, the network device can indicate multiple cycles to the terminal device, for example, different cycles can correspond to different states of the network device, so that the cycle of the terminal device can match each state of the network device as much as possible, thereby reducing the power consumption of the terminal device.

[0243] The technical solution provided in the embodiment of the present application can be applied to the fourth generation mobile communication technology (the 4th generation, 4G) 4G system, such as the LTE system, or can be applied to the 5G system, such as the NR system, or can also be applied to the next generation mobile communication system or other similar communication systems, without specific limitation.

[0244] The following describes a network architecture used in the embodiments of the present application. Figure 2 .

[0245] Figure 2 It includes network devices and terminal devices, and the terminal device is connected to a network device. Figure 2 The number of terminal devices is only an example. In actual applications, the network device can provide services for multiple terminal devices. Figure 2 The network device in the embodiment, and each terminal device of some or all of the terminal devices in the plurality of terminal devices can implement the technical solution provided in the embodiment of the present application. In addition, Figure 2 The terminal device in the description is a mobile phone as an example, but is not limited to this in actual applications.

[0246] Figure 2 The network device in the embodiment is, for example, an access network device, such as a base station, or may also be a device such as an RSU. Among them, the base station corresponds to different devices in different systems, for example, it may correspond to an eNB in ​​a 4G system and may correspond to a gNB in ​​a 5G system. Of course, the technical solution provided in the embodiment of the present application may also be applied to future mobile communication systems, so Figure 2 The network equipment in the present invention may also correspond to the access network equipment in the future mobile communication system.

[0247] The technical solution provided by the embodiments of the present application is described below in conjunction with the accompanying drawings.

[0248] The present application embodiment provides a first communication method, see Figure 3 , which is a flowchart of the method. In the following introduction, the method is applied to Figure 2 The network architecture shown is taken as an example. In addition, the method can be performed by two communication devices, such as a first communication device and a second communication device, wherein the first communication device can be a network device or a communication device capable of supporting the network device to implement the functions required by the method, or the first communication device can be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by the method, and of course it can also be other communication devices, such as a chip system. The same is true for the second communication device, the second communication device can be a network device or a communication device capable of supporting the network device to implement the functions required by the method, or the second communication device can be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by the method, and of course it can also be other communication devices, such as a chip system. And there is no restriction on the implementation methods of the first communication device and the second communication device, for example, the first communication device can be a network device, the second communication device is a terminal device, or the first communication device and the second communication device are both network devices, or the first communication device and the second communication device are both terminal devices, or the first communication device is a network device, and the second communication device is a communication device capable of supporting the terminal device to implement the functions required by the method, and so on. Among them, the network device is, for example, a base station.

[0249] For the sake of convenience, the following takes the method being performed by a network device and a terminal device as an example, that is, the first communication device is a network device and the second communication device is a terminal device as an example. Figure 2 The network architecture shown in FIG. 1 is taken as an example, therefore, the network devices described below may be Figure 2 The network device in the network architecture shown in the figure, the terminal device described below can be Figure 2 Terminal devices in the network architecture shown.

[0250] S31. The network device determines a first signaling, where the first signaling is used to indicate at least one period, and one of the at least one period is a period for the terminal device to detect a downlink signal.

[0251] The network device can determine at least one cycle that the terminal device needs to execute. As an optional method, the sleep mode of the network device and the cycle of the terminal device detecting the downlink signal can be one-to-one corresponding. Then, the at least one cycle can be matched with at least one sleep mode. A cycle matches a sleep mode. For example, one matching method is that the difference between the length of the cycle and the sleep granularity of the sleep mode is less than a first threshold. The first threshold is, for example, configured by the network device, or specified by a protocol. If the first threshold is 0, the length of the cycle is equal to the sleep granularity of the sleep mode. The first threshold may also not be used. When a cycle matches a sleep mode, the sleep granularity of the sleep mode is directly used as the length of the cycle. For example, if the sleep granularity of a sleep mode is 1ms, the corresponding cycle determined by the network device may also be 1ms.

[0252] Determining at least one cycle described herein may be determining the length of at least one cycle. In at least one cycle, the lengths of different cycles may be different, or the lengths of different cycles may be the same. The length of the cycle described in the embodiment of the present application refers to the time domain length of the cycle.

[0253] For example, before entering the sleep mode, the network device may determine at least one sleep mode to be entered, and according to the determined sleep mode, the corresponding period may be determined.

[0254] The number of at least one sleep mode may be 1. For example, the network device may enter multiple sleep modes in sequence, but before entering each sleep mode, the network device only determines the next sleep mode to be entered. In this case, the number of at least one sleep mode is 1, and the number of at least one cycle is also 1. Alternatively, the number of at least one sleep mode may be greater than 1. For example, the network device may enter multiple sleep modes in sequence, and before entering the first sleep mode, the network device may determine all sleep modes to be entered. In this case, the number of at least one sleep mode is greater than 1, and the number of at least one cycle is also greater than 1.

[0255] Alternatively, if the number of at least one sleep mode is greater than 1, there may be a situation where the network device enters multiple sleep modes in sequence, and before entering a sleep mode, the network device can determine some sleep modes to enter next, but the number of these sleep modes is greater than 1. In this case, the number of at least one sleep mode is greater than 1, and the number of at least one cycle is also greater than 1.

[0256] If the number of at least one cycle is greater than 1, then the terminal device also involves the order when executing at least one cycle. Therefore, the network device can also determine the order of at least one cycle, that is, determine the order in which the terminal device detects with at least one cycle. For example, the network device can randomly determine the order of at least one cycle, or, if the cycle corresponds to the sleep mode one by one, then the network device can determine the order of at least one sleep mode, and the order of at least one sleep mode can be the same as the order of the corresponding at least one cycle. Therefore, the network device determines the order of at least one sleep mode, and also determines the order of at least one cycle.

[0257] The order of at least one sleep mode reflects the order in which the network device enters the corresponding sleep mode, that is, which sleep mode the network device enters first and which sleep mode it enters later. For example, if the network device determines that it is about to enter sleep mode 1, sleep mode 2, and sleep mode 3, the network device can determine the order of the three sleep modes, that is, the network device first enters sleep mode 2, then enters sleep mode 3, and finally enters sleep mode 1.

[0258] The order of at least one sleep mode can be flexible, or in other words, the network device can flexibly determine the order of at least one sleep mode. For example, the at least one sleep mode determined by the network device is sleep mode 1, sleep mode 2, and sleep mode 3. The network device can execute one or more rounds of each of the three sleep modes. Then these three sleep modes will correspond to multiple orders. The network device can determine any order corresponding to the three sleep modes as the actual order of the three sleep modes, and is not restricted by any factors when determining the order. For example, the network device will execute one round of sleep mode 1, two rounds of sleep mode 2, and one round of sleep mode 3. The order of the three sleep modes determined by the network device can be sleep mode 2-sleep mode 3-sleep mode 2-sleep mode 1, which can be referred to Figure 4A Then, the order of the corresponding at least one cycle may be: the cycle corresponding to sleep mode 2 - the cycle corresponding to sleep mode 3 - the cycle corresponding to sleep mode 2 - the cycle corresponding to sleep mode 1. In this case, the order of the at least one cycle is also flexible.

[0259] Alternatively, the network device may determine the order of at least one sleep mode based on the power consumption corresponding to the network device. For example, in at least one sleep mode, the power consumption of the network device when it is in the sleep mode that comes first in the order is less than the power consumption of the network device when it is in the sleep mode that comes later in the order. For example, the at least one sleep mode determined by the network device is sleep mode 1, sleep mode 2, and sleep mode 3. The power consumption of the network device when it is in sleep mode 1 is power consumption 1, the power consumption when it is in sleep mode 2 is power consumption 2, and the power consumption when it is in sleep mode 3 is power consumption 3. Power consumption 1> power consumption 2> power consumption 3. Then, the order of the three sleep modes determined by the network device may be sleep mode 3-sleep mode 2-sleep mode 1. Please refer to Figure 4B Then, the order of at least one corresponding cycle can be: cycle corresponding to sleep mode 3 - cycle corresponding to sleep mode 2 - cycle corresponding to sleep mode 1. This is equivalent to the network device performing "from deep to shallow" sleep. The network device performs sleep in this "from deep to shallow" manner, which is the most energy-saving sleep mode.

[0260] If this is the case, it is equivalent to that the network device determines the order of at least one cycle according to the power consumption corresponding to the network device. If the network device determines the order of at least one cycle according to the power consumption of the network device, then, for example, in at least one cycle, the length of the cycle in the previous order can be greater than the length of the cycle in the next order. If the cycle corresponds to the sleep mode one by one, then this can also be understood as the power consumption of the network device in the sleep mode corresponding to the cycle in the previous order is less than the power consumption of the network device in the sleep mode corresponding to the cycle in the next order.

[0261] Alternatively, the network device may determine the order of at least one sleep mode based on the wake-up time corresponding to the network device. For example, in at least one sleep mode, the wake-up time when the network device is in the sleep mode that comes first in the order is greater than the wake-up time when the network device is in the sleep mode that comes later in the order. For example, the at least one sleep mode determined by the network device is sleep mode 1, sleep mode 2, and sleep mode 3. The wake-up time when the network device is in sleep mode 1 is wake-up time 1, the wake-up time when it is in sleep mode 2 is wake-up time 2, and the wake-up time when it is in sleep mode 3 is wake-up time 3. Wake-up time 1<wake-up time 2<wake-up time 3. Then, the order of the three sleep modes determined by the network device may be sleep mode 3-sleep mode 2-sleep mode 1, which can be referred to in Figure 4B Then, the order of at least one corresponding cycle can be: the cycle corresponding to sleep mode 3 - the cycle corresponding to sleep mode 2 - the cycle corresponding to sleep mode 1. This is equivalent to the network device performing sleep with the wake-up time from long to short. The network device performs sleep in this way of wake-up time from long to short, which is the sleep mode that can best reduce the wake-up delay.

[0262] If this is the case, it is equivalent to that the network device determines the order of at least one cycle according to the wake-up time corresponding to the network device. If the network device determines the order of at least one cycle according to the wake-up time of the network device, then, for example, in at least one cycle, the length of the cycle in the previous order can be greater than the length of the cycle in the next order. If the cycle corresponds to the sleep mode one by one, then this can also be understood as that the wake-up time when the network device is in the sleep mode corresponding to the cycle in the previous order is greater than the wake-up time when the network device is in the sleep mode corresponding to the cycle in the next order.

[0263] Alternatively, the network device may also determine the order of at least one sleep mode according to the hardware condition of the network device.

[0264] For example, if the hardware of the network device cannot support the network device to directly enter a certain sleep mode, then the network device can first enter other sleep modes, and then enter the sleep mode from other sleep modes. For example, at least one sleep mode determined by the network device is sleep mode 1 and sleep mode 2. The network device cannot support directly entering sleep mode 2, but can support directly entering sleep mode 1. Therefore, the network device determines to enter sleep mode 1 first, and then enter sleep mode 2. In other words, the order of the two sleep modes determined by the network device can be sleep mode 1-sleep mode 2, such as Figure 4C Then, the order of the corresponding at least one cycle can be the cycle corresponding to the sleep mode 1 - the cycle corresponding to the sleep mode 2.

[0265] For another example, if the hardware of the network device cannot support the network device to directly return to the active state from a certain sleep mode, then the network device can return to the active state from other sleep modes. For example, at least one sleep mode determined by the network device is sleep mode 1 and sleep mode 2. The network device cannot support returning to the active state from sleep mode 2, but can support returning to the active state from sleep mode 1. Then the order of the two sleep modes that can be determined by the network device can be sleep mode 2-sleep mode 1, such as Figure 4D Then, the order of the corresponding at least one cycle can be the cycle corresponding to the sleep mode 2 - the cycle corresponding to the sleep mode 1.

[0266] If this is the case, it is equivalent to that the network device determines the order of at least one cycle according to the hardware conditions of the network device. If the network device determines the order of at least one cycle according to the hardware conditions of the network device, for example, if the hardware of the network device does not support directly entering a cycle with a longer length, the network device can put the order of the cycle with a shorter length in front, then in at least one cycle, the length of the cycle in the order can be less than the length of the cycle in the order. For another example, if the hardware of the network device does not support the network device to directly exit from a cycle with a longer length, the network device can also put the cycle with a longer length in front and the cycle with a shorter length in the back, then in at least one cycle, the length of the cycle in the order can be greater than the length of the cycle in the order.

[0267] Of course, in addition to the above methods, the network device can also use other methods to determine the order of at least one sleep mode, which is equivalent to using other methods to determine the order of at least one cycle. The embodiments of the present application do not limit this.

[0268] Alternatively, the network device may obtain multiple cycle sets, each of which may include one cycle, or include a sequential combination of multiple cycles. For example, the network device may set multiple cycle sets by itself, or the multiple cycle sets may be specified by a protocol. For example, multiple cycle sets include cycle set 1, cycle set 2, and cycle set 3, cycle set 1 includes cycle 2-cycle 3, and includes cycle 2 with a detection number of n2 and cycle 3 with a detection number of n3, which indicates that cycle set 1 includes two cycles, cycle 2 and cycle 3, and includes the order and detection number of these two cycles. Cycle set 2 includes cycle 3-cycle 2-cycle 1, and includes cycle 3 with a detection number of n3, cycle 2 with a detection number of n2, and cycle 1 with a detection number of n1, which indicates that cycle set 2 includes three cycles, cycle 1, cycle 2, and cycle 3, and includes the order and detection number of these three cycles. Cycle set 3 includes cycle 1-cycle 2, and the number of detections of cycle 1 is n1, and the number of detections of cycle 2 is n2, which means that cycle set 3 includes two cycles, cycle 1 and cycle 2, and includes the order and number of detections of these two cycles. The number of detections of the cycle will be introduced in the next step.

[0269] Then, if the network device wants to determine at least one cycle, it can directly determine a cycle set from multiple cycle sets. Determining the cycle set means determining at least one cycle. For example, the network device determines the first cycle set, and the first cycle set can correspond to at least one cycle, or the first cycle set can correspond to the sequence combination of at least one cycle. The way in which the network device determines the first cycle set is, for example, random determination, for example, the network device can flexibly determine at least one cycle, and can also flexibly determine the sequence of at least one cycle, then the network device can randomly determine the first cycle set; or, the network device can also determine the first cycle set according to the principle of "from deep to shallow", for example, the network device can determine the sequence of at least one cycle according to the principle of "from deep to shallow", and then determine the first cycle set according to the sequence of at least one cycle; or, the network device can also determine the first cycle set according to the hardware conditions of the network device, for example, the network device can determine the sequence of at least one cycle according to the hardware conditions of the network device, and then determine the first cycle set according to the sequence of at least one cycle; or, the network device can also determine the first cycle set according to the wake-up time of the network device, for example, the network device can determine the sequence of at least one cycle according to the length of the wake-up time of the network device, and then determine the first cycle set according to the sequence of at least one cycle.

[0270] For example, if the cycle corresponds to the sleep mode one-to-one, then the network device can also obtain multiple sleep mode sets (or sleep patterns, etc.), and the sleep mode sets correspond to the cycle sets one-to-one. The network device determines a sleep mode set from the multiple sleep mode sets, and also determines the corresponding cycle set.

[0271] For example, each sleep mode set in multiple sleep mode sets may include one sleep mode, or include a sequential combination of multiple sleep modes. For example, a network device may set multiple sleep mode sets by itself, or multiple sleep mode sets may also be specified by a protocol. For example, multiple sleep mode sets include sleep mode set 1, sleep mode set 2, and sleep mode set 3, sleep mode set 1 includes sleep mode 2-sleep mode 3, and includes sleep mode 2 with a repetition number of n2, and sleep mode 3 with a repetition number of n3, which indicates that sleep mode set 1 includes two sleep modes, sleep mode 2 and sleep mode 3, and includes the order and repetition number of these two sleep modes. Sleep mode set 2 includes sleep mode 3-sleep mode 2-sleep mode 1, and includes sleep mode 3 with a repetition number of n3, sleep mode 2 with a repetition number of n2, and sleep mode 1 with a repetition number of n1, which indicates that sleep mode set 1 includes three sleep modes, sleep mode 1, sleep mode 2, and sleep mode 3, and includes the order and repetition number of these three sleep modes. Sleep mode set 3 includes sleep mode 1-sleep mode 2, and the number of repetitions of sleep mode 1 is n1, and the number of repetitions of sleep mode 2 is n2, which means that sleep mode set 3 includes two sleep modes, sleep mode 1 and sleep mode 2, and includes the order and repetition number of these two sleep modes. The number of repetitions of the sleep mode will also be introduced in the next step.

[0272] Then, if the network device wants to determine at least one sleep mode to be entered, it can directly determine a sleep mode set from multiple sleep mode sets. Determining the sleep mode set means determining at least one sleep mode. For example, if the network device determines the first sleep mode set, the first sleep mode set can correspond to at least one sleep mode, or in other words, the first sleep mode set can correspond to a sequential combination of at least one sleep mode. The first sleep mode set also corresponds to the first period set. Therefore, if the network device determines the first sleep mode set, it also determines the first period set. The network device determines the first sleep mode set in a manner such as random determination. For example, the network device can flexibly determine at least one sleep mode and can also flexibly determine the order of at least one sleep mode. In this case, the network device can randomly determine the first sleep mode set; or, the network device can determine the first sleep mode set according to the principle of "from deep to shallow". For example, the network device can determine the order of at least one sleep mode according to the principle of "from deep to shallow", and then determine the first sleep mode set according to the order of at least one sleep mode; or, the network device can determine the first sleep mode set according to the hardware conditions of the network device. For example, the network device can determine the order of at least one sleep mode according to the hardware conditions of the network device, and then determine the first sleep mode set according to the order of at least one sleep mode; or, the network device can determine the first sleep mode set according to the wake-up time of the network device. For example, the network device can determine the order of at least one sleep mode according to the length of the wake-up time of the network device, and then determine the first sleep mode set according to the order of at least one sleep mode.

[0273] In addition, according to Table 1 above, for the sleep mode, there may be corresponding deactivation time and activation time. The deactivation time of a sleep mode refers to the time required for the network device to enter the sleep mode from the activated state; the activation time of a sleep mode refers to the time required for the network device to enter the activated state from the sleep mode. The switching time required for the network device to switch from one sleep mode (for example, sleep mode A) to another sleep mode (for example, sleep mode B) is related to one or more of the activation time of sleep mode A, the deactivation time of sleep mode B, the deactivation time of sleep mode A, or the activation time of sleep mode B.

[0274] During the activation time, deactivation time, or switching time of a sleep mode from one sleep mode to another, the network device generally does not send a downlink signal, so the terminal device does not need to detect the downlink signal, or the terminal device can continue to detect the downlink signal according to the original cycle. After the deactivation time of a sleep mode or the switching time from another sleep mode to the sleep mode ends, the sleep mode is actually entered, and the network device goes into sleep. At this time, the terminal device can change the original cycle of the terminal device according to at least one cycle.

[0275] At least one cycle may correspond to one or more offsets, and the number of offsets corresponding to at least one cycle may be equal to or may not be equal to the number of at least one cycle.

[0276] In addition to indicating at least one period to the terminal device, the network device may also indicate to the terminal device one or more offsets corresponding to at least one period, and the one or more offsets may assist the terminal device in detection. For example, the network device may indicate an offset to the terminal device, such as Figure 4E , the network device indicates to the terminal device that at least one cycle is cycle 2 (T2) and cycle 1 (T1), the order of at least one cycle is T2-T1, the number of detections corresponding to at least one cycle is n2-n1, and the offset P2. Alternatively, the network device may also indicate multiple offsets to the terminal device, such as Figure 4F , the network device indicates to the terminal device that at least one cycle includes cycle 1 (T1), cycle 2 (T2) and cycle 3 (T3), the order of at least one cycle is T2-T3-T2-T1, and the number of detections corresponding to at least one cycle is n2-n3-n ′ 2-n1, multiple offsets are P2-P3-P ′ 2-P1.

[0277] For example, the network device may indicate one or more offsets to the terminal device through the first signaling, and the terminal device may determine the one or more offsets after receiving the first signaling. Alternatively, the network device may indicate one or more offsets to the terminal device through other signaling.

[0278] Or there is another situation, if the offset corresponding to at least one cycle is very short and can be ignored, then the network device does not need to indicate the offset of at least one cycle. For example, some manufacturers' hardware devices have better performance, so that the deactivation time when the network device enters a sleep mode is short, the activation time when exiting from a sleep mode is also short, and the switching time from one sleep mode to another is also short, which does not affect the terminal device to detect the downlink signal, then the network device does not need to indicate the offset of at least one cycle.

[0279] Optionally, if the number of at least one cycle is 1, then the first signaling indicates at least one cycle, and one indication method is that the first signaling indicates a first duration, and the first duration is related to one of the at least one cycle. If the number of at least one cycle is 1, then one of the at least one cycle refers to this cycle, for example, the cycle is called the fourth cycle. For example, the first duration is the total duration of the terminal device detecting with the cycle corresponding to the first duration. For example, if the cycle matches the sleep mode, then the first duration can be the total duration of the network device in the sleep mode. When the network device is in the sleep mode, the terminal device detects with the cycle corresponding to the first duration, so the first duration can also be considered as the total duration of the terminal device detecting with this cycle.

[0280] The terminal device may determine the fourth period according to the first duration. For example, the terminal device may determine the fourth period according to the first duration and at least one threshold. Among them, at least one threshold may be included in the first signaling, or the network device may configure at least one threshold to the terminal device in advance, or at least one threshold may be preconfigured in the terminal device, or at least one threshold may be specified by a protocol. Among them, the terminal device may select a period from the first set according to the first duration, and the period is the fourth period. The first set may include one or more periods. The first set may be specified by a protocol, or the network device may configure the first set to the terminal device in advance, or the first set may be preconfigured in the terminal device, or the first set may also be indicated by the first signaling. Optionally, the period in the first set may match the sleep granularity of the network device. It should be noted that the first set described here is a different concept from the period set described above. The first set described here includes one or more periods, and there is no sequential relationship between the periods included in the first set. The terminal device may select a period from the one or more periods to execute according to the first duration.

[0281] After receiving the first signaling, the terminal device can select a period from the first set as the period for the terminal device to detect the downlink signal according to the first duration indicated by the first signaling and at least one threshold (that is, select the fourth period), and then the terminal device will detect the downlink signal according to the selected period. For example, at least one threshold can form one or more threshold ranges, and each threshold range can correspond to a period. The terminal device determines the threshold range to which the first duration belongs, and the period corresponding to this threshold range is the period corresponding to the first duration, and the terminal device can determine to use this period to detect the downlink signal. In addition, if the first duration is the total duration of the network device in the sleep mode, and the terminal device selects the corresponding period, then the terminal device can determine the number of detections of this period according to the first duration and the length of this period. Therefore, if the first signaling indicates the first duration, then the first signaling does not have to indicate the number of detections of this period.

[0282] For example, at least one threshold can include two thresholds, namely Th1 and Th2, where Th1 < Th2. The first set includes period A, period B, and period C, and the value of the first duration is Z. Among them, the threshold range (0, Th1) corresponds to period A, the threshold range [Th1, Th2] corresponds to period B, and the threshold range (Th2, +∞) corresponds to period C. If 0 < Z < Th1, the terminal device can select period A from the first set; if Th1 ≤ Z < Th2, the terminal device can select period B from the first set; if Z ≥ Th2, the terminal device can select period C from the first set. The terminal device can detect the downlink signal according to the selected period.

[0283] According to the above introduction, it can be seen that the value of the first duration can be related to the value of the period, and the value of the period can refer to the length of the period. For example, at least one threshold includes two thresholds Th1 and Th2, where Th1 < Th2. Let X and Y be two positive numbers. If the value of the first duration is X, then the first duration corresponds to period A; if the value of the first duration is Y, then the first duration corresponds to period B. If X is not equal to Y, then A is not equal to B. For example, if 0 < X < Th1 and Th1 ≤ Y < Th2, that is, X is not equal to Y, then A ≠ B. That is to say, the value of the first duration can be related to the value of the period. If two possible values X and Y of the first duration are not equal, then the two possible values of the corresponding period are also not equal.

[0284] Optionally, the value of the first duration may be proportional to the value of the period. For example, at least one threshold may include two thresholds Th1 and Th2, where Th1 < Th2. Let X and Y be two positive numbers. If the value of the first duration is X, the corresponding period is period A. If the value of the first duration is Y, the corresponding period is period B. If X is less than Y, then A is less than B. For example, if 0 < X < Th1 and Th1 ≤ Y < Th2, that is, X < Y, then A is less than B, which means that the value of the first duration may be proportional to the value of the one period.

[0285] S32. The network device sends a first signaling, and the terminal device receives the first signaling from the network device.

[0286] After determining at least one period, the network device may send a first signaling, and the first signaling may indicate at least one period. Among them, if the network device directly determines at least one period, the first signaling may indicate at least one period. For example, the first signaling may include at least one period, or it can be said that the first signaling may include the length of at least one period. For example, the first signaling includes the length of each period in at least one period. Or, if the network device determines a first period set, the first signaling may include at least one period, or it can be said that the first signaling may include the length of at least one period, or it may also include the identifier of the first period set. The identifier of the first period set may indicate the first period set, and the first period set includes the sequential combination of the at least one period. Therefore, the identifier of the first period set can also indicate at least one period. For example, the identifier of the first period set includes the number or identity number (ID) of the first period set, etc.

[0287] As a way for the first signaling to indicate at least one period, the first signaling may include at least one period. Or, if the number of at least one period is 1, as another way for the first signaling to indicate at least one period, the first signaling may indicate the first duration, and the corresponding period can be indicated by the first duration.

[0288] Among them, if the network device has configured multiple period sets to the terminal device in advance, or multiple period sets can be pre-configured in the terminal device, or multiple period sets are specified by the protocol, then the first signaling may include an identifier of the first period set, which can reduce the signaling overhead; or, if multiple period sets are not configured for the terminal device in advance, the first signaling may still include at least one period, which can make it unnecessary for the terminal device to perceive the period set, simplifying the implementation of the terminal device. Among them, if the network device configures multiple period sets to the terminal device, then, for example, the network device can send a third signaling, and the third signaling is used to indicate multiple period sets. After the terminal device receives the third signaling from the network device, it can determine multiple period sets. The third signaling can be a unicast signaling, a multicast signaling, or a broadcast signaling, without specific limitation.

[0289] Wherein, if the network device configures at least one threshold value to the terminal device, then, for example, the network device may send a fifth signaling, and the fifth signaling is used to indicate at least one threshold value. After the terminal device receives the fifth signaling from the network device, the at least one threshold value may be determined. The fifth signaling may be a unicast signaling, a multicast signaling, or a broadcast signaling, and is not specifically limited. Alternatively, the network device may also configure at least one threshold value to the terminal device through the first signaling.

[0290] If the network device configures the first set to the terminal device, for example, the network device may send a sixth signaling, and the sixth signaling is used to indicate the first set. After the terminal device receives the sixth signaling from the network device, the first set can be determined. The sixth signaling may be a unicast signaling, a multicast signaling, or a broadcast signaling, and is not specifically limited. Alternatively, the network device may also configure the first set to the terminal device through the first signaling.

[0291] The first signaling may be unicast signaling, multicast signaling, or broadcast signaling. For example, if the first signaling is unicast signaling, the first signaling may be directed to only one terminal device. For example, the network device may send the first signaling only to the terminal device that needs to save power consumption, without sending the first signaling to multiple terminal devices covered by the network device, so that the first signaling is more targeted. Alternatively, if the first signaling is multicast signaling, the first signaling may be UE group signaling, which may be directed to multiple terminal devices, and these multiple terminal devices may all apply the at least one period to detect downlink signals. Alternatively, if the first signaling is broadcast signaling, for example, for a cell, the at least one period may be applied to detect downlink signals, and the network device may indicate the at least one period through broadcast signaling. If the first signaling is multicast signaling or broadcast signaling, signaling overhead may be saved to a certain extent.

[0292] If the first signaling is unicast signaling or multicast signaling, the first signaling may be RRC signaling, or may be signaling carried in PDCCH, such as downlink control information (DCI). If the first signaling is broadcast signaling, the first signaling may be a system message, such as a master information block (MIB) or a system information block (SIB). If the first signaling is RRC signaling, the network device may send the first signaling in a semi-static manner, which may improve the reliability of the signaling; if the first signaling is signaling carried in PDCCH, the network device may send the first signaling dynamically, which may save the time for the network device to notify the terminal device, so that the network device may enter sleep mode more quickly.

[0293] It is introduced in S31 that if the number of at least one cycle is greater than 1, then the terminal device will have a corresponding order when detecting according to at least one cycle, or when the terminal device executes the at least one cycle. Optionally, if the number of at least one cycle is greater than 1, the first signaling can also indicate the order of at least one cycle, or in other words, indicate the order in which the terminal device detects with at least one cycle. This is equivalent to indicating the order of at least one cycle in an explicit manner. If at least one cycle matches at least one sleep mode, then the order of at least one cycle and the order of the corresponding at least one sleep mode can be the same, so that the terminal device can detect the downlink signal according to the cycle that matches the sleep mode of the network device.

[0294] Alternatively, the first signaling may indicate at least one cycle, but not the order of at least one cycle. The order of at least one cycle may be predefined or determined implicitly. For example, the network device and the terminal device default that the network device preferentially enters a sleep mode with lower sleep power consumption. For example, the lower the power consumption of the sleep mode, the longer the corresponding cycle. In other words, the network device and the terminal device both default that the order of the cycle with a longer length is before the cycle with a shorter length. In this way, the first signaling does not need to include the order of at least one cycle. After receiving the first signaling, the terminal device will perform cycle detection in an implicit manner that prioritizes detection of cycles with longer lengths.

[0295] For another example, the hardware of the network device cannot support the network device to directly enter a certain sleep mode. For example, if the network device wants to enter sleep mode 2, it must first enter sleep mode 1 for transition before entering sleep mode 2, and the terminal device is also aware of this. Then the network device and the terminal device default that the order of the period corresponding to sleep mode 1 is before the period corresponding to sleep mode 2. If the first signaling includes the period corresponding to sleep mode 2 and the period corresponding to sleep mode 1, then the first signaling may not include the order of these two periods. After receiving the first signaling, the terminal device will detect in a manner that the order of the period corresponding to sleep mode 1 is before the period corresponding to sleep mode 2. Alternatively, if the first signaling includes the period corresponding to sleep mode 2, but does not include the period corresponding to sleep mode 1 as a transition, then the network device and the terminal device default that the network device will still enter sleep mode 1 for transition before entering sleep mode 2. When the network device is in sleep mode 1 transition, the number of detections n1 of the period corresponding to sleep mode 1 can be a predefined value. After receiving the first signaling, the terminal device will perform periodic detection in an implicit manner, first detecting n1 times with the period corresponding to sleep mode one and then detecting with the period corresponding to sleep mode two.

[0296] For another example, the hardware of the network device cannot support the network device to return to the active state directly from a certain sleep mode. For example, the network device cannot return to the active state directly from sleep mode 2, and must first enter sleep mode 1 for transition before entering the active state, and the terminal device is also aware of this. Then the network device and the terminal device can default that the order of the period corresponding to sleep mode 2 is located before the period corresponding to sleep mode 1. If the first signaling includes the period corresponding to sleep mode 2 and the period corresponding to sleep mode 1, then the first signaling may not include the order of these two periods. After receiving the first signaling, the terminal device will detect in a manner that the order of the period corresponding to sleep mode 2 is located before the period corresponding to sleep mode 1. Alternatively, if the first signaling includes the period corresponding to sleep mode 2, but does not include the period corresponding to sleep mode 1 as a transition, then the network device and the terminal device can default that the network device will still first enter sleep mode 1 for transition before returning to the active state from sleep mode 2. When the network device is in sleep mode 1 transition, the number of detections n1 of the period corresponding to sleep mode 1 can be a predefined value. After receiving the first signaling, the terminal device will perform detection by first executing the cycle corresponding to sleep mode 2 and then executing the cycle corresponding to sleep mode 1.

[0297] When the network device executes at least one sleep mode, each of the sleep modes may be executed in one or more rounds, and when executing a round of a certain sleep mode, the network device may execute it once or more times. For example, the at least one sleep mode determined by the network device includes sleep mode 1, sleep mode 2, and sleep mode 3, and the network device determines the order of these three sleep modes as sleep mode 2-sleep mode 3-sleep mode 2-sleep mode 1, that is, the network device will execute one round of sleep mode 1, one round of sleep mode 3, and two rounds of sleep mode 2. For example, when the network device executes the first round of sleep mode 2, the number of repetitions corresponding to sleep mode 2 is 2 times, indicating that the network device will execute sleep mode 2 twice; when the network device executes sleep mode 3, the number of repetitions corresponding to sleep mode 3 is 2 times, indicating that the network device will execute sleep mode 3 twice; when the network device executes the second round of sleep mode 2, the number of repetitions corresponding to sleep mode 2 is 3 times, indicating that the network device will execute sleep mode 2 3 times; when the network device executes sleep mode 1, the number of repetitions corresponding to sleep mode 1 is 3 times, indicating that the network device will execute sleep mode 1 3 times. You can continue to refer to Figure 4A , where T2 represents the period corresponding to sleep mode 2, T3 represents the period corresponding to sleep mode 3, and T1 represents the period corresponding to sleep mode 1.

[0298] It can be seen that for a sleep mode, if the network device repeatedly executes the sleep mode, the cycle of the terminal device will be repeated accordingly, or in other words, the terminal device will also repeatedly detect the downlink signal accordingly. However, the number of times the network device repeats the sleep mode can be the same as or different from the number of times the terminal device detects the downlink signal. For the sleep mode, if the network device repeats it multiple times, then the number can be called the number of repetitions of the sleep mode, or the number of cycles of the sleep mode, etc. On the terminal device side, it means that the terminal device needs to perform multiple detections according to a cycle. For example, as an optional implementation, the first signaling can also indicate the number of times the terminal device detects in at least one cycle, or the number of times the terminal device executes at least one cycle, or the number of repetitions (or cycles) of at least one cycle, and so on. The number of times the terminal device detects in a cycle described here means that the interval between two adjacent detections satisfies the cycle, or the number of times the terminal device executes the cycle, rather than the number of times the terminal device detects the downlink signal within the cycle. For example Figure 4A For sleep mode 3, the network device will execute it twice. Then, corresponding to the terminal device side, the period indicated by the network device (for example, the period corresponding to sleep mode 3) is T3. It can be seen that the terminal device also needs to detect twice according to T3, or in other words, T3 will be repeated twice.

[0299] In addition, for Figure 4B , Figure 4C and Figure 4D The meanings of T1, T2, T3, etc. are also the same as Figure 4A Same as in.

[0300] If the cycle corresponds to the sleep mode one-to-one, the number of times the terminal device detects in a cycle (also referred to as the number of detections in the cycle) is related to the number of repetitions of the sleep mode that matches the cycle. For example, the two can be equal, or they can be unequal. For example, when the two are equal, the length of the cycle × the number of times the terminal device detects according to the cycle (or the number of repetitions of the sleep mode corresponding to the cycle) is equal to the total duration of the terminal device detecting the downlink signal in the cycle. The sleep granularity × the number of repetitions of the sleep mode is equal to the total sleep duration of the network device in the sleep mode. Among them, if the cycle corresponds to the sleep mode one-to-one, the length of the cycle can be equal to the sleep granularity of the sleep mode, and the number of times the terminal device detects in a cycle can be equal to the number of repetitions of the sleep mode corresponding to the cycle.

[0301] If the first signaling also indicates the number of times the terminal device performs detection in at least one cycle, then the first signaling can also indicate the order in which the terminal device performs detection in at least one cycle. For example, at least one cycle includes cycle 1, cycle 2, and cycle 3, and the order of these three cycles is cycle 2-cycle 3-cycle 2-cycle 1. The first signaling can indicate that the number of detections corresponding to this order is 2-2-4-3, so that the terminal device can determine the number of detections for each cycle according to the first signaling.

[0302] As an optional implementation, if the network device configures the terminal device to execute only once for each of at least one period, then the first signaling may not necessarily indicate the number of times the terminal device performs detection in at least one period, or, for each of at least one period, a fixed number of detections is specified, for example, the network device can be configured in advance, or it can be specified by a protocol, etc., then the first signaling may not necessarily indicate the number of times the terminal device performs detection in at least one period.

[0303] However, it should be noted that if the number of at least one cycle is greater than 1, then in the at least one cycle, different cycles may have different lengths, or two or more cycles may have the same length. If two cycles have the same length, for the convenience of description, the two cycles can still be regarded as different cycles. The number of detections corresponding to the two cycles can be the same or different.

[0304] For example, the network device executes two rounds of sleep mode 2, and the repetition times corresponding to the two rounds of sleep mode 2 are different, for example, the repetition times of the first round of sleep mode 2 is 2, and the repetition times of the second round of sleep mode 2 is 4. Then it is also considered that the period corresponding to the first round of sleep mode 2 is period 1, and the period corresponding to the second round of sleep mode 2 is period 2, except that the length of period 1 is the same as the length of period 2.

[0305] If the first signaling also indicates an offset, for example Figure 4E , the first signaling indicates at least one period and an offset, then the terminal device can perform detection based on the offset and at least one period.

[0306] Alternatively, if the first signaling further indicates multiple offsets, the terminal device may perform detection according to the multiple offsets and at least one period. Figure 4F At least one cycle includes cycle 1, cycle 2, and cycle 3. The order of the three cycles is cycle 2-cycle 3-cycle 2-cycle 1. The first signaling may indicate that the offset corresponding to the order is 2ms-2.5ms-1ms-0.5ms. For example, the terminal device needs to experience a 2ms offset before executing cycle 2, and the terminal device needs to experience a 2.5ms offset after executing cycle 2 and before executing cycle 3, and so on.

[0307] The network device may indicate all the cycles that the terminal device needs to execute through the first signaling, and the at least one cycle includes all the cycles that the terminal device needs to execute. Alternatively, the network device may indicate part of the cycles that the terminal device needs to execute through the first signaling, and the at least one cycle includes only part of the cycles that the terminal device needs to execute.

[0308] For example, the cycle corresponds to the sleep mode one by one, so for example, the network device will enter multiple sleep modes in sequence, but before entering each sleep mode, the network device only determines the part of the sleep mode that will be entered next. In this case, at least one sleep mode in S31 is only a part of the sleep mode to be executed by the network device, rather than all the sleep modes to be executed by the network device. And at least one cycle indicated in S32 is the part of the cycle that the terminal device needs to execute. Alternatively, the network device will enter multiple sleep modes in sequence, and before entering the sleep mode, the network device will still determine all the sleep modes to be executed, but when the network device sends the first signaling to the terminal device, it will only indicate the cycle corresponding to the part of the sleep mode that will be entered next. In this case, at least one sleep mode in S31 is also only a part of the sleep mode to be executed by the network device, rather than all the sleep modes to be executed by the network device. And at least one cycle indicated in S32 is the part of the cycle that the terminal device needs to execute.

[0309] If the terminal device needs to execute multiple cycles in sequence, and the first signaling only indicates a portion of the cycles to be executed next, that is, the at least one cycle is only a portion of the cycle to be executed by the terminal device. Then the network device can also send a second signaling to the terminal device. For example, the terminal device can receive the second signaling when or before the at least one cycle is completed. The second signaling can indicate one or more cycles, and the one or more cycles are located after the at least one cycle in sequence. For example, if the number of the one or more cycles is 1, and the cycle is the first cycle, the second signaling can indicate the first cycle that is located after the at least one cycle in sequence.

[0310] For example, the network device will enter multiple sleep modes in sequence, and the first signaling only indicates the period corresponding to some of the sleep modes that will be entered next. Then, when the network device wakes up from at least one sleep mode, it can send a second signaling, and the second signaling can indicate the first period corresponding to the next sleep mode that is sequentially located after at least one sleep mode. Optionally, the second signaling can also indicate the number of times the terminal device performs detection in the first period. Optionally, the second signaling can also indicate the corresponding offset. Similarly, the second signaling can be unicast signaling, multicast signaling or broadcast signaling. For the implementation of the second signaling, please refer to the introduction of the first signaling.

[0311] After the network device notifies the terminal device of all the cycles that the terminal device needs to execute, the network device may not need to notify again. For example, if the network device wakes up from the last sleep mode in the sequence of all sleep modes that need to be executed, the network device can directly return to the activated state without sending the second signaling. For example, the sleep modes that the network device determines to be executed are sleep mode 3-sleep mode 2-sleep mode 1, and the network device only notifies the terminal device of the cycle corresponding to the next sleep mode to be executed each time. For example, if the network device wakes up from sleep mode 3, it can send the second signaling, and the second signaling indicates the cycle corresponding to sleep mode 2. If the network device wakes up from sleep mode 2, it can send the second signaling again, and the second signaling at this time indicates the cycle corresponding to sleep mode 1. If the network device wakes up from sleep mode 1, it does not need to send the second signaling, but returns to the activated state.

[0312] S33. The terminal device detects the downlink signal according to at least one period.

[0313] After receiving the first signaling, the terminal device can determine at least one period according to the first signaling. Wherein, if the first signaling indicates the first duration, the terminal device can determine the fourth period according to the first duration, because in this case the number of at least one period is 1, so the at least one period is the fourth period. For example, the terminal device can determine the fourth period according to the first duration, at least one threshold value and the first set. For example, if the first signaling is a signaling carried by PDCCH, such as DCI, the terminal device can directly apply at least one period to the second search space, so that the terminal device can detect downlink signals according to at least one period in the second search space. Alternatively, if the first signaling is a signaling carried by PDCCH, or the first signaling is RRC signaling, or the first signaling is a system message, the terminal device can directly apply at least one period to all search spaces supported by the terminal device, then the terminal device can detect downlink signals according to at least one period in each search space of all supported search spaces. Wherein, the second search space is, for example, the search space in which the terminal device receives the first signaling. Applying a period to a search space means replacing the period of the search space with the period. Optionally, the terminal device may not measure and / or provide feedback on the channel status during the period of detecting the downlink signal according to at least one period.

[0314] Before the terminal device replaces the period of the search space, the original period of the search space may be configured by the network device through RRC signaling. It can be seen that in the embodiment of the present application, although the first signaling may be RRC signaling or may not be RRC signaling, no matter what type of signaling the first signaling is, the terminal device can replace the original period configured by the network device through RRC signaling according to at least one period indicated by the first signaling. In this sense, at least one period can be used to change the period of the first search space of the terminal device to at least one period, the first search space is the search space for sending the first signaling (at this time, the first search space and the second search space refer to the same search space), or the first search space is any one of all search spaces supported by the terminal device.

[0315] Alternatively, after receiving the first signaling, the terminal device may also make a corresponding judgment to determine whether to detect the downlink signal according to at least one cycle. In an embodiment of the present application, if the terminal device determines whether to detect the downlink signal according to at least one cycle after receiving the first signaling, then one judgment method may be to judge according to the cycle of the search space. The following describes the method in which the terminal device judges according to the cycle of the search space. Among them, when judging according to the cycle of the search space, if the first signaling only indicates one cycle, the terminal device can directly judge according to the cycle indicated by the first signaling. If the first signaling indicates multiple cycles, the terminal device can only judge according to the next cycle that the terminal device is about to execute indicated by the first signaling, without judging each cycle. When the terminal device completes one cycle and needs to execute the next cycle, the terminal device can judge according to the next cycle indicated by the first signaling. For example, the first signaling indicates cycle 1 and cycle 2. According to the instruction of the first signaling, the terminal device determines to execute cycle 1 first and then cycle 2. Then, before executing cycle 1, the terminal device can first make a judgment based on the cycle of the search space (i.e., the original cycle of the search space) and cycle 1, and determine whether to modify the cycle of the search space based on the judgment result; when cycle 1 is completed and cycle 2 is about to be executed, or before executing cycle 2, the terminal device can first make a judgment based on the cycle of the search space and cycle 2, and determine whether to modify the cycle of the search space based on the judgment result.

[0316] For example, the terminal device needs to make a judgment based on the period of the first search space and the third period of at least one period, then the terminal device can determine whether the period of the first search space is greater than the third period. If the period of the first search space is less than or equal to the third period, the terminal device can replace the period of the first search space with the third period, and the terminal device can detect the downlink signal in the first search space according to the third period. Alternatively, if the period of the first search space is greater than the third period, the terminal device can replace the period of the first search space with M times the third period, that is, the terminal device can detect the downlink signal in the first search space according to the period of M×P, where P represents the length of the third period and M is a positive integer. The value of M×P can be made as close as possible to the length of the original period of the first search space, so that the change to the period of the first search space is small, which is more conducive to the implementation of the terminal device. Alternatively, if the period of the first search space is greater than the third period, the terminal device can replace the period of the first search space with the third period, or the terminal device can set the period of the first search space to the least common multiple of the original period of the first search space and the third period.

[0317] If the first signaling is a signaling carried by PDCCH, the first search space may be the second search space as described above, that is, the search space in which the terminal device receives the first signaling, or the first search space may be any one of all the search spaces supported by the terminal device. If the first signaling is not a signaling carried by PDCCH, the first search space may be any one of all the search spaces supported by the terminal device. That is to say, if the first signaling is a signaling carried by PDCCH, the terminal device may only make a judgment on the second search space, and for other search spaces supported by the terminal device except the second search space, the terminal device does not apply at least one period to these search spaces, that is, for other search spaces supported by the terminal device except the second search space, the terminal device continues to use the original period of these search spaces to detect downlink signals; or, the first signaling may be a signaling carried by PDCCH, or may not be a signaling carried by PDCCH, then the terminal device may make a judgment on each search space in all the search spaces supported by the terminal device, and the terminal device may detect downlink signals according to the third period in each search space in all the search spaces supported by the terminal device.

[0318] For example, if the original period of the first search space is 0.5 ms and the third period is 1 ms, the period of the first search space is smaller than the third period. Then the terminal device can modify the period of the first search space to 1 ms, and the terminal device can detect downlink signals in the first search space according to the period of 1 ms.

[0319] Alternatively, if the original period of the first search space is 3.2ms and the third period is 1ms, the period of the first search space is greater than the third period. Then the terminal device can modify the period of the first search space to 3ms, or to 4ms, etc., in accordance with the principle of making the value of M×P as close as possible to the length of the original period of the first search space; or, in accordance with the principle of replacing the period of the first search space with the third period, modify the period of the first search space to 1ms; or, in accordance with the principle of setting the period of the first search space to the least common multiple of the original period of the first search space and the third period, modify the period of the first search space to 16ms. The terminal device can detect the downlink signal in the first search space according to the modified period.

[0320] The terminal device can determine whether to modify the period of the first search space based on the judgment result, so that the modification of the period of the search space by the terminal device can be more reasonable.

[0321] For example, the order of at least one sleep mode is sleep mode 2-sleep mode 3-sleep mode 2-sleep mode 1, the order of at least one cycle is T2-T3-T2-T1, T1 represents the length of the cycle of sleep mode 1, T2 represents the length of the cycle of sleep mode 2, T3 represents the length of the cycle of sleep mode 3, and the number of detections corresponding to at least one cycle is n2-n3-n ′ 2-n1. For example, for the first search space, the terminal device may first adjust the period of the first search space to T2 that matches sleep mode 2. After detecting according to T2 and / or n2, the network device will enter sleep mode 3, and the terminal device will also adjust the period of the first search space to T3 that matches sleep mode 3. After detecting according to T3 and / or n3, the network device will enter sleep mode 2, and the terminal device will also adjust the period of the first search space to T2 that matches sleep mode 2. After detecting according to T2 and / or n3, the network device will enter sleep mode 2, and the terminal device will also adjust the period of the first search space to T2 that matches sleep mode 2. ′ After detecting according to T1 and / or n1, the network device ends the sleep state and enters the active state, at which time the terminal device will also detect the downlink signal from the awakened network device.

[0322] If the first signaling also indicates one or more offsets, or the network device indicates one or more offsets through other signaling, the terminal device also needs to consider the one or more offsets when detecting the downlink signal according to the first period.

[0323] For example, the order of at least one sleep mode is sleep mode 2-sleep mode 3-sleep mode 2-sleep mode 1, the order of at least one cycle is T2-T3-T2-T1, and the number of detections corresponding to at least one cycle is n2-n3-n ′ 2-n1, the offset corresponding to at least one period is P2-P3-P ′ 2-P1. For example, for the first search space, the terminal device can adjust the period of the first search space to T2 matching sleep mode 2 according to P2 and / or T2 after receiving the first signaling. After detecting according to P2 and / or T2 and / or n2, the network device will enter sleep mode 3, and the terminal device will adjust the period of the first search space to T3 matching sleep mode 3 according to offset P3 and / or T3. After detecting according to P3 and / or T3 and / or n3, the network device will enter sleep mode 2, and the terminal device will adjust the period of the first search space to T3 matching sleep mode 3 according to offset P3 and / or T3 and / or n3. ′ 2 and / or T2, the period of the first search space is adjusted to the period T2 matching the sleep mode 2. ′ 2 and / or T2 and n ′After 2 detections, the network device will enter sleep mode 1, and the terminal device will adjust the period of the first search space to T1 matching sleep mode 1 according to the offset P1 and / or T1. After detecting according to P1 and / or T1 and / or n1, the network device ends the sleep state and enters the active state, at which time the terminal device will also detect the downlink signal from the awakened network device.

[0324] S34. The network device receives downlink services.

[0325] For example, the network device receives downlink services during the Nth repetition of a first sleep mode in at least one sleep mode, or the network device receives downlink services at the end of the Nth repetition of a first sleep mode in at least one sleep mode, wherein N is a positive integer, the Nth repetition may be any repetition of the first sleep mode, and the first sleep mode may be any sleep mode in at least one sleep mode.

[0326] For example, the network device receives a downlink service from the core network device during the Nth repetition process of the first sleep mode or at the end of the Nth repetition process, and the downlink service corresponds to the terminal device, for example, the terminal device in S33. The first sleep mode can be any one of the at least one sleep mode, and the Nth repetition process can be any repetition process of the first sleep mode.

[0327] The first sleep mode can be any one of at least one sleep mode, and the number of repetitions of the first sleep mode can be greater than or equal to N. Among them, if the first sleep mode is the last sleep mode in the sequence of at least one sleep mode, and the number of repetitions of the first sleep mode is equal to N, and the network device receives downlink services at the end of the Nth repetition process of the first sleep mode in at least one sleep mode, in this case, it can be considered that the network device wakes up after at least one sleep mode is executed. If the network device wakes up after at least one sleep mode is executed, the network device may receive downlink services, or it is also possible that even if the network device does not receive downlink services, the network device will wake up after at least one sleep mode is executed. S34 only takes the network device receiving downlink services as an example.

[0328] S35. The network device wakes up after the Nth repetition process of the first sleep mode in at least one sleep mode is completed. In addition, the network device no longer executes the remaining repetition processes of the first sleep mode except the Nth repetition process, and no longer executes other sleep modes in the at least one sleep mode that are sequentially located after the first sleep mode.

[0329] If a network device receives a downlink service during the sleep process, the network device can wake up in time to execute the downlink service as soon as possible and reduce the delay of the downlink service. For example, the sleep mode to be executed by the network device is sleep mode 3-sleep mode 2-sleep mode 1, where the number of repetitions of sleep mode 3 is 6, the number of repetitions of sleep mode 2 is 2, and the number of repetitions of sleep mode 1 is 2. For example, the network device receives a downlink service during the third repetition of sleep mode 3. At this time, sleep mode 3 has been repeated 2 times and is now in the third repetition of sleep mode 3, and there are still 3 repetitions of sleep mode 3 that have not been executed. However, the network device can still start to wake up after the third repetition of sleep mode 3. The network device will no longer execute the 3 repetitions of sleep mode 3 that have not been executed, as well as the subsequent sleep mode 2 and sleep mode 1.

[0330] S36. After waking up, the network device sends a fourth signaling to the terminal device.

[0331] For the terminal device, the fourth signaling from the network device may be received during the Nth detection of the fifth cycle in at least one cycle, wherein the Nth detection may be any detection of the fifth cycle, and the fifth cycle may be any cycle in at least one cycle.

[0332] If the first sleep mode is the last sleep mode in at least one sleep mode, the fifth cycle can be the last cycle in at least one cycle, otherwise, the fifth cycle is not the last cycle in at least one cycle. The number of repetitions of the first sleep mode may be equal to the number of detections in the fifth cycle, or may not be equal to. For example, when the two are equal, if the number of repetitions of the first sleep mode is equal to N, the number of detections in the fifth cycle is equal to N, and if the number of repetitions of the first sleep mode is greater than N, the number of detections in the fifth cycle is greater than N.

[0333] Among them, if the fifth cycle is the last cycle in sequence in at least one cycle, and the number of detections of the fifth cycle is equal to N, and the terminal device receives the fourth signaling from the network device during the Nth detection of the fifth cycle in at least one cycle, then it can be considered that the terminal device received the fourth signaling after at least one cycle has been executed, that is, the terminal device normally corresponds to the sleep mode of the network device.

[0334] Alternatively, if the number of at least one cycle is 1, if the number of detections of the fifth cycle is equal to N, and the terminal device receives the fourth signaling from the network device during the Nth detection of the fifth cycle in at least one cycle, it can be considered that the terminal device received the fourth signaling after at least one cycle has been executed. For example, if the first signaling indicates a first duration, the terminal device may receive the fourth signaling at the end of the first duration or after the end of the first duration.

[0335] For example, the cycle of the terminal device matches the sleep mode of the network device, so the terminal device can receive the fourth signaling sent by the network device after waking up. After receiving the fourth signaling, the terminal device can perform normal business with the network device.

[0336] For example, the fourth signaling may be a signaling carried by the PDCCH. For example, the fourth signaling is a wake-up signal (WUS) for waking up the terminal device; or, the fourth signaling is a signaling for scheduling downlink data or uplink data, such as DCI; or, the fourth signaling is a signaling for transmitting special information, such as tsunami information or earthquake information. Of course, the fourth signaling may also be other signaling, and the fourth signaling may also have other uses.

[0337] S37. The terminal device uses a second period to detect a downlink control channel, and the second period does not belong to at least one period.

[0338] After receiving the fourth signaling, the terminal device may modify the period of the terminal device to the second period. Alternatively, even if the terminal device does not receive the fourth signaling, the terminal device may modify the period of the terminal device to the second period after executing at least one period (here, at least one period is taken as an example of all periods indicated by the network device to the terminal device). Optionally, if the terminal device did not measure and / or feedback the channel state during the detection of the downlink signal according to at least one period, the terminal device may resume the measurement and / or feedback of the channel state after receiving the fourth signaling; alternatively, the terminal device may not resume the measurement and / or feedback of the channel state at this time, that is, whether to resume the measurement and / or feedback of the channel state may be independent of the fourth signaling.

[0339] Among them, the terminal device can modify the periods of the search spaces modified by the terminal device in S33 to the second period in S37; or, no matter which search spaces the terminal device modifies in S33 to the second period, the terminal device can modify the period of each search space in all search spaces supported by the terminal device in S37, or the terminal device can only modify the period of the search space for receiving the fourth signaling to the second period in S37.

[0340] The second cycle does not belong to at least one cycle, nor is it the first cycle. In other words, the second cycle is not a cycle that matches at least one sleep mode of the network device. The second cycle should be the cycle of the terminal device when both the terminal device and the network device are working normally.

[0341] For example, the second cycle may be the original cycle of the terminal device before the terminal device modifies the cycle of the terminal device in S33, or the second cycle may be the original cycle of the terminal device before the network device enters sleep mode, or before the terminal device receives the first signaling; or, the second cycle may also be the cycle indicated by the fourth signaling; or, the second cycle may also be the cycle specified by the protocol, and so on.

[0342] Among them, S34 to S37 are only optional steps and are not required to be executed.

[0343] In the embodiment of the present application, after determining that the network device is about to enter at least one sleep mode, the network device can indicate at least one cycle to the terminal device, and at least one cycle can match at least one sleep mode, so that the terminal device can detect the downlink signal according to at least one cycle, which is equivalent to the terminal device can detect the downlink signal according to the sleep mode of the network device, and try to avoid the terminal device still detecting the downlink signal according to the cycle when the network device is in the active state when the network device is in the sleep mode, reducing the probability of the terminal device doing useless work and reducing the power consumption of the terminal device. Moreover, the cycle and the sleep mode of the network device can correspond. If the network device may be in multiple sleep modes in sequence, the number of at least one cycle can be greater than 1, that is, the network device can indicate multiple cycles to the terminal device. When the network device is in a sleep mode, the terminal device can detect the downlink signal according to the cycle matching the sleep mode, so that the cycle of the terminal device can match each sleep mode of the network device, reducing the power consumption of the terminal device.

[0344] exist Figure 3 In the embodiment shown, the network device indicates at least one cycle. In another case, the terminal device may only need to detect the downlink signal according to one cycle to match the state of the network device. To this end, the embodiment of the present application provides a second communication method, Figure 5 is a flowchart of the method. In the following introduction, the method is applied to Figure 2The network architecture shown is taken as an example. In addition, the method can be performed by two communication devices, such as a first communication device and a second communication device, wherein the first communication device can be a network device or a communication device capable of supporting the network device to implement the functions required by the method, or the first communication device can be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by the method, and of course it can also be other communication devices, such as a chip system. The same is true for the second communication device, the second communication device can be a network device or a communication device capable of supporting the network device to implement the functions required by the method, or the second communication device can be a terminal device or a communication device capable of supporting the terminal device to implement the functions required by the method, and of course it can also be other communication devices, such as a chip system. And there is no restriction on the implementation methods of the first communication device and the second communication device, for example, the first communication device can be a network device, the second communication device is a terminal device, or the first communication device and the second communication device are both network devices, or the first communication device and the second communication device are both terminal devices, or the first communication device is a network device, and the second communication device is a communication device capable of supporting the terminal device to implement the functions required by the method, and so on. Among them, the network device is, for example, a base station.

[0345] For the sake of convenience, the following takes the method being performed by a network device and a terminal device as an example, that is, the first communication device is a network device and the second communication device is a terminal device as an example. Figure 2 The network architecture shown in FIG. 1 is taken as an example, therefore, the network devices described below may be Figure 2 The network device in the network architecture shown in the figure, the terminal device described below can be Figure 2 Terminal devices in the network architecture shown.

[0346] S51. The network device determines a first signaling, where the first signaling is used to indicate a first number or a first duration, where the first number is the number of times the terminal device performs detection according to a first cycle, and the first duration is the duration for the terminal device to perform detection according to the first cycle.

[0347] In an embodiment of the present application, the network device may determine a first period, and the first period is used by the terminal device to detect a downlink signal. For example, the length of the first period is already known to the terminal device, for example, the network device has been configured to the terminal device, or the first period may be pre-configured in the terminal device, or the first period is specified by a protocol. Then the network device only needs to indicate the number of detections of the first period to the terminal device through the first signaling. Alternatively, if the terminal device does not know the length of the first period, the first signaling may also indicate the length of the first period; or, the network device may send a third signaling to indicate the length of the first period through the third signaling. After receiving the third signaling, the terminal device can determine the length of the first period.

[0348] For example, the first cycle matches the sleep mode of the network device. For example, if the network device only supports one sleep mode, the network device only needs to determine a cycle that matches the sleep mode. A cycle matches a sleep mode, for example, a matching method is that the difference between the length of the cycle and the sleep granularity of the sleep mode is less than a first threshold. The first threshold is, for example, configured by the network device, or specified by a protocol. If the first threshold is 0, the length of the cycle is equal to the sleep granularity of the sleep mode. For example, the sleep granularity of a sleep mode is 1ms, and the corresponding cycle determined by the network device may also be 1ms.

[0349] Optionally, the first signaling may also indicate an offset, or the network device may also indicate the offset through other signaling. For example, the first signaling may indicate one or more offsets. These offsets may assist the terminal device in detecting the first period. For more description of the offset of the period, refer to Figure 3 S31 in the embodiment shown.

[0350] Alternatively, the first signaling may not necessarily indicate the first number, but may indicate the first duration, for example, the first duration is the total duration for the terminal device to perform detection in the first cycle. For example, if the cycle matches the sleep mode, then the first duration may be the total duration for the network device to be in sleep mode. When the network device is in sleep mode, the terminal device performs detection in the first cycle, so the first duration may also be considered as the total duration for the terminal device to perform detection in the first cycle. If the first duration is the total duration for the network device to be in sleep mode, and the terminal device can determine the first cycle, then the terminal device can determine the number of detections in the first cycle based on the first duration and the length of the first cycle. Therefore, if the first signaling indicates the first duration, then the first signaling may not necessarily indicate the first number.

[0351] S52: The network device sends a first signaling, and the terminal device receives the first signaling from the network device.

[0352] The first signaling may be a unicast signaling, a multicast signaling, or a broadcast signaling. For example, if the first signaling is a unicast signaling, the first signaling may be directed to only one terminal device. For example, the network device may send the first signaling only to the terminal device that needs to save power consumption, without sending the first signaling to multiple terminal devices covered by the network device, so that the first signaling is more targeted. Alternatively, if the first signaling is a multicast signaling, the first signaling may be a UE group signaling, which may be directed to multiple terminal devices, and these multiple terminal devices may all apply the first period to detect downlink signals. Alternatively, if the first signaling is a broadcast signaling, for example, for a cell, the first period may be applied to detect downlink signals, and the network device may indicate the first period through a broadcast signaling. If the first signaling is a multicast signaling or a broadcast signaling, the signaling overhead may be saved to a certain extent.

[0353] If the first signaling is unicast signaling or multicast signaling, the first signaling may be RRC signaling, or may be signaling carried in PDCCH, such as DCI. If the first signaling is broadcast signaling, the first signaling may be a system message, such as MIB or SIB. If the first signaling is RRC signaling, the network device may send the first signaling in a semi-static manner, which may improve the reliability of the signaling; if the first signaling is signaling carried in PDCCH, the network device may send the first signaling dynamically, which may save the time for the network device to notify the terminal device, so that the network device can enter the sleep mode more quickly.

[0354] S53. The terminal device detects the downlink signal according to the first cycle.

[0355] After receiving the first signaling, if the first signaling indicates the first number, the terminal device can determine the first number; or, if the first signaling indicates the first duration, since the terminal device can determine the first period, the terminal device can also determine the first number based on the first duration and the first period. After determining the first number, the terminal device can detect the downlink signal based on the first period and / or the first number.

[0356] For example, if the first signaling is a signaling carried by PDCCH, such as DCI, the terminal device can directly apply the first period to the second search space, so that the terminal device can detect the downlink signal according to the first period in the second search space. Alternatively, if the first signaling is a signaling carried by PDCCH, or the first signaling is RRC signaling, or the first signaling is a system message, the terminal device can directly apply the first period to all search spaces supported by the terminal device, and the terminal device can detect the downlink signal according to the first period in each search space of all supported search spaces. Among them, the second search space is, for example, the search space where the terminal device receives the first signaling. Applying a period to a search space means replacing the period of the search space with the period.

[0357] Before the terminal device replaces the period of the search space, the original period of the search space may be configured by the network device through RRC signaling. It can be seen that in the embodiment of the present application, although the first signaling may be RRC signaling or may not be RRC signaling, no matter what type of signaling the first signaling is, the terminal device can replace the original period configured by the network device through RRC signaling according to the first period after receiving the first signaling. In this sense, the first period can be used to change the period of the first search space of the terminal device to the first period, and the first search space is the search space for sending the first signaling (at this time, the first search space and the second search space refer to the same search space), or the first search space is any one of all search spaces supported by the terminal device.

[0358] Alternatively, after receiving the first signaling, the terminal device may also make a corresponding judgment to determine whether to detect the downlink signal according to the first period. In an embodiment of the present application, if the terminal device determines whether to detect the downlink signal according to the first period after receiving the first signaling, then one judgment method may be to make a judgment based on the period of the search space. The following describes a method in which the terminal device makes a judgment based on the period of the search space.

[0359] For example, the terminal device may determine whether the period of the first search space is greater than the first period. If the period of the first search space is less than or equal to the first period, the terminal device may replace the period of the first search space with the first period, and the terminal device may detect the downlink signal in the first search space according to the first period. Alternatively, if the period of the first search space is greater than the first period, the terminal device may replace the period of the first search space with M times the first period, that is, the terminal device may detect the PDCCH in the first search space according to the period of M×P, where P represents the length of the first period and M is a positive integer. The value of M×P may be made as close as possible to the length of the original period of the first search space, so that the change to the period of the first search space is small, which is more conducive to the implementation of the terminal device. Alternatively, if the period of the first search space is greater than the first period, the terminal device may replace the period of the first search space with the first period, or the terminal device may set the period of the first search space to the least common multiple of the original period of the first search space and the first period.

[0360] If the first signaling is a signaling carried by PDCCH, the first search space may be the second search space as described above, i.e., the search space in which the terminal device receives the first signaling, or the first search space may be any one of all search spaces supported by the terminal device. If the first signaling is not a signaling carried by PDCCH, the first search space may be any one of all search spaces supported by the terminal device.

[0361] If the first signaling also indicates an offset, or the network device indicates an offset through other signaling, the terminal device also needs to consider the offset when detecting the downlink signal according to the first period.

[0362] For more information about how to determine the terminal device, please refer to Figure 3 Relevant content in S33 in the illustrated embodiment.

[0363] S54. The network device receives downlink services.

[0364] For example, the network device receives downlink services during the Nth repetition process of the sleep mode or at the end of the Nth repetition process, where N is a positive integer. The Nth repetition process can be any repetition process of the sleep mode. If the network device wakes up after the sleep mode is completed, the network device may receive downlink services, or it is also possible that even if the network device does not receive downlink services, the network device will wake up after the sleep mode is completed. S54 only takes the network device receiving downlink services as an example.

[0365] For more information about S54, please refer to Figure 3 Relevant content in S34 in the illustrated embodiment.

[0366] S55: The network device wakes up after the Nth repetition process of the sleep mode is completed. In addition, the network device no longer executes the remaining repetition processes of the sleep mode except the Nth repetition process.

[0367] If the network device receives downlink services during the sleep process, the network device can wake up in time to execute the downlink services as soon as possible and reduce the delay of the downlink services. For example, the network device receives downlink services during the third repetition of the sleep mode. The number of repetitions of sleep mode 3 is 6. At this time, the sleep mode has been repeated 2 times and is now in the third repetition of the sleep mode. There are still 3 repetitions of the sleep mode that have not been executed. However, the network device can still wake up after the third repetition of the sleep mode ends. This is equivalent to the network device waking up before the first duration ends. The network device will no longer execute the 3 repetitions of the sleep mode that have not been executed.

[0368] Alternatively, the network device may also wake up at the end of the sleep mode or after the end of the sleep mode. For example, the network device receives downlink services during the sixth repetition of the sleep mode, and the number of repetitions of sleep mode 3 is 6. At this time, the sleep mode has been repeated 5 times, and it is now in the sixth repetition of the sleep mode. Then the network device can start to wake up after the sixth repetition of the sleep mode ends. This is equivalent to the network device starting to wake up at the end of the first duration.

[0369] Alternatively, the network device may not receive any downlink service, and the network device may also start to wake up when or after the sleep mode ends.

[0370] S56, after waking up, the network device sends a second signaling to the terminal device. For the terminal device, it receives the second signaling from the network device during the Nth detection in the first cycle, wherein the Nth detection can be any detection in the first cycle.

[0371] In other words, the terminal device may receive the second signaling from the network device before the first time period ends; or, the terminal device may receive the second signaling from the network device at the end of the first time period or after the first time period ends.

[0372] For example, the cycle of the terminal device matches the sleep mode of the network device, so the terminal device can receive the second signaling sent by the network device after waking up. After receiving the second signaling, the terminal device can perform normal business with the network device.

[0373] For example, the second signaling may be a signaling carried by the PDCCH. For example, the second signaling is a WUS for waking up the terminal device; or, the second signaling is a signaling for scheduling downlink data or uplink data, such as DCI; or, the second signaling is a signaling for transmitting special information, such as tsunami information or earthquake information. Of course, the second signaling may also be other signaling, and the second signaling may also have other uses.

[0374] For more information about S56, please refer to Figure 3 Relevant content in S36 in the illustrated embodiment.

[0375] S57. The terminal device uses a second period to detect the downlink control channel, and the second period is not the same as the first period.

[0376] After receiving the second signaling, the terminal device may modify the period of the terminal device to the second period. Alternatively, even if the terminal device does not receive the second signaling, the terminal device may modify the period of the terminal device to the second period after executing at least one period.

[0377] Among them, the terminal device can modify the periods of the search spaces modified by the terminal device in S53 to the second period in S57; or, no matter which search spaces the terminal device modifies in S53 to the second period, the terminal device can modify the period of each search space in all search spaces supported by the terminal device in S57, or the terminal device can only modify the period of the search space for receiving the second signaling to the second period in S57.

[0378] The second cycle is not the same as the first cycle. In other words, the second cycle is not a cycle that matches the sleep mode of the network device. The second cycle should be the cycle of the terminal device when both the terminal device and the network device are working normally.

[0379] For example, the second period may be the original period of the terminal device before the terminal device modifies the period of the terminal device in S53, or the second period may be the original period of the terminal device before the network device enters sleep mode or before the terminal device receives the first signaling; or the second period may be the period indicated by the second signaling; or the second period may be the period specified by the protocol, and so on.

[0380] Among them, S54 to S57 are only optional steps and are not required to be executed.

[0381] Similar to Figure 3As described in S33 and S37 in the illustrated embodiment, optionally, the terminal device may not perform measurement and / or feedback of the channel state during the period of detecting the downlink signal according to the first period; correspondingly, after receiving the second signaling, the terminal device may resume the measurement and / or feedback of the channel state, or may not resume the measurement and / or feedback of the channel state at this time, that is, whether to resume the measurement and / or feedback of the channel state may be independent of the second signaling.

[0382] In an embodiment of the present application, after determining the sleep mode of the network device, the network device can indicate the number of detections in the first cycle to the terminal device. The first cycle can match the sleep mode, so that the terminal device can detect the downlink signal according to the first cycle, which is equivalent to the terminal device detecting the downlink signal according to the sleep mode of the network device. This avoids the terminal device detecting the downlink signal according to the cycle when the network device is in an activated state when the network device is in sleep mode, thereby reducing the probability of the terminal device doing useless work and reducing the power consumption of the terminal device.

[0467] The embodiment of the present application further provides a communication device, which can be a terminal device or a circuit. The communication device can be used to execute the actions executed by the terminal device in the above method embodiment.

[0468] When the communication device is a terminal device, Fig.10 A simplified schematic diagram of the structure of a terminal device is shown. For ease of understanding and illustration, Fig.10 In the example, a mobile phone is used as the terminal device. Fig.10 As shown, the terminal device includes a processor, a memory, a radio frequency circuit, an antenna, and an input-output device. The processor is mainly used to process communication protocols and communication data, as well as to control the terminal device, execute software programs, process software program data, etc. The memory is mainly used to store software programs and data. The radio frequency circuit is mainly used for conversion between baseband signals and radio frequency signals and processing of radio frequency signals. The antenna is mainly used to send and receive radio frequency signals in the form of electromagnetic waves. Input-output devices, such as touch screens, display screens, keyboards, etc., are mainly used to receive data input by users and output data to users. It should be noted that some types of terminal devices may not have input-output devices.

[0469] When data needs to be sent, the processor performs baseband processing on the data to be sent and outputs the baseband signal to the RF circuit. The RF circuit performs RF processing on the baseband signal and then sends the RF signal outward in the form of electromagnetic waves through the antenna. When data is sent to the terminal device, the RF circuit receives the RF signal through the antenna, converts the RF signal into a baseband signal, and outputs the baseband signal to the processor. The processor converts the baseband signal into data and processes the data. For ease of explanation, Fig.10 Only one memory and processor are shown. In an actual terminal device product, there may be one or more processors and one or more memories. The memory may also be referred to as a storage medium or a storage device. The memory may be set independently of the processor or may be integrated with the processor, and the embodiments of the present application do not limit this.

[0470] In the embodiments of the present application, the antenna and the radio frequency circuit with transceiver functions may be regarded as the transceiver unit of the terminal device (the transceiver unit may be a functional unit that can realize the sending function and the receiving function; or the transceiver unit may also include two functional units, namely, a receiving unit that can realize the receiving function and a sending unit that can realize the sending function), and the processor with processing function may be regarded as the processing unit of the terminal device. Fig.10As shown, the terminal device includes a transceiver unit 1010 and a processing unit 1020. The transceiver unit may also be referred to as a transceiver, a transceiver, a transceiver device, etc. The processing unit may also be referred to as a processor, a processing board, a processing module, a processing device, etc. Optionally, the device used to implement the receiving function in the transceiver unit 1010 may be regarded as a receiving unit, and the device used to implement the sending function in the transceiver unit 1010 may be regarded as a sending unit, that is, the transceiver unit 1010 includes a receiving unit and a sending unit. The transceiver unit may also be sometimes referred to as a transceiver, a transceiver, or a transceiver circuit, etc. The receiving unit may also be sometimes referred to as a receiver, a receiver, or a receiving circuit, etc. The sending unit may also be sometimes referred to as a transmitter, a transmitter, or a transmitting circuit, etc.

[0471] It should be understood that the transceiver unit 1010 is used to perform sending operations and receiving operations on the terminal device side in the above method embodiment, and the processing unit 1020 is used to perform other operations except the sending and receiving operations on the terminal device in the above method embodiment.

[0472] For example, in one implementation, the transceiver unit 1010 is used to execute Figure 3 All sending operations and receiving operations of the terminal device in the embodiment shown, such as S32 and S36, and / or the transceiver unit 1010 is also used to perform other processes supporting the technology described herein.
