Description

Technical Field

[0001] The present invention relates to the field of wireless communication technologies, and in particular to a monitoring method and device, a computer program product, and a readable storage medium. Background Art

[0002] To improve the battery life of terminal equipment, the Third Generation Partnership Project (3GPP) rd The Third Generation Partnership Project (3GPP) is discussing the Low Power Wake Up Signal (LP-WUS). The terminal device contains a main receiver (that is, a receiver used for normal data communication) and a low power receiver. When the main receiver has no business transmission or no data scheduling, the main receiver can enter a sleep state (deep sleep / light sleep / micro sleep) and does not perform physical downlink control channel (PDCCH) monitoring activities. The low power receiver can receive a low power wake-up signal to determine whether to wake up the main receiver to perform PDCCH monitoring. How the terminal device monitors the low power wake-up signal to achieve energy saving in the Radio Resource Control (RRC) connection state is an urgent problem to be solved. Summary of the Invention

[0003] One of the purposes of the present invention is to provide a monitoring method to reduce the number of times a terminal device monitors a low-power wake-up signal and reduce the power consumption of the terminal device.

[0004] In a first aspect, the present invention provides a monitoring method, comprising: determining whether to monitor a target low-power wake-up signal within a target time window based on indication information, or determining not to monitor the target low-power wake-up signal within the target time window; the target low-power wake-up signal is used to indicate whether a terminal device monitors PDCCH.

[0005] Based on the indication information, the terminal device determines whether to monitor the target low-power wake-up signal within the target time window, or determines not to monitor the target low-power wake-up signal within the target time window. If the terminal device determines to monitor the target low-power wake-up signal within the target time window, it starts monitoring the target low-power wake-up signal. Otherwise, the terminal device does not monitor the target low-power wake-up signal within the target time window. In this way, unnecessary monitoring of low-power wake-up signals can be avoided, reducing the power consumption of the terminal device.

[0006] Optionally, the target time window includes at least one of the following: a discontinuous reception DRX duration, a valid time range of the DRX duration and a DRX inactivity timer, and a time window for monitoring a PDCCH.

[0007] The terminal device can monitor the target low-power wake-up signal within the DRX duration. Alternatively, the terminal device can monitor the target low-power wake-up signal within the effective time range of the DRX duration and the DRX inactivity timer. Therefore, the technical solution of the present application can be compatible with existing communication protocols. In addition, the terminal device can monitor the target low-power wake-up signal within the activation time window for monitoring PDCCH, and the activation time window can correspond to a time window similar to DRX defined in a subsequently evolved communication protocol. Therefore, the technical solution of the present application can also be compatible with subsequently evolved communication protocols.

[0008] Optionally, the indication information is carried by a first low-power wake-up signal.

[0009] Outside the target time window, the terminal device may receive the first low-power wake-up signal. Based on the first low-power wake-up signal, the terminal device monitors the target low-power wake-up signal within the target time window. Thus, the first low-power wake-up signal instructs the terminal device to monitor the target low-power wake-up signal within the target time window.

[0010] Optionally, the terminal device can also obtain first configuration information; the first configuration information is used to configure a first listening opportunity and a second listening opportunity, the first listening opportunity is used to listen to the first low-power wake-up signal, and the first listening opportunity is outside the target time window; the second listening opportunity is used to listen to the target low-power wake-up signal, and the second listening opportunity is within the target time window.

[0011] The network device can configure a first listening opportunity and a second listening opportunity for the terminal device through the first configuration information. The terminal device determines the first listening opportunity and the second listening opportunity based on the first configuration information. The terminal device listens for the first low-power wake-up signal at the first listening opportunity and listens for the target low-power wake-up signal at the second listening opportunity. While determining the specific listening opportunity, the low-power receiver of the terminal device does not need to be awake for a long time, thereby reducing the power consumption of the terminal device.

[0012] Optionally, the first configuration information includes a first configuration parameter and a second configuration parameter, the first configuration parameter is used to determine the first monitoring timing, and the second configuration parameter is used to determine the second monitoring timing.

[0013] The terminal device can obtain the first configuration parameter and the second configuration parameter based on the first configuration information sent by the network device, and then determine the first monitoring time based on the first configuration parameter and determine the second monitoring time based on the second configuration parameter.

[0014] Optionally, the first configuration parameters include at least one of the following: the time domain starting position of the first listening opportunity, the number of symbols occupied by the first listening opportunity, the period of the first listening opportunity, and the offset between the time domain starting position of the target time window; the second configuration parameters include at least one of the following: the time domain starting position of the second listening opportunity, the number of symbols occupied by the second listening opportunity, and the period of the second listening opportunity.

[0015] The first configuration information sent by the network device includes a first configuration parameter and a second configuration parameter. The first configuration parameter and the second configuration parameter can be the same. In other words, the network device only needs to be configured with a common configuration parameter, and the terminal device can determine the first listening opportunity and the second listening opportunity based on the common configuration parameter. As a result, the amount of data corresponding to the configuration parameter sent by the network device is relatively small, which can reduce the downlink overhead of the network device.

[0016] The first configuration parameter and the second configuration parameter may also be different, and the terminal device may determine the first monitoring opportunity based on the first configuration parameter and the second monitoring opportunity based on the second configuration parameter. Thus, the network device can flexibly configure the first monitoring opportunity and the second monitoring opportunity.

[0017] In some embodiments, the first configuration parameter configured by the network device includes an offset from a time domain start position of a target time window, and the period of the first listening opportunity can be associated with the target time window. Thus, the first configuration parameter has fewer contents, which can reduce the downlink overhead of the network device.

[0018] Optionally, the target time window includes the DRX duration, and the indication information is carried by the downlink control information of format 2-6; and / or, the target time window includes the DRX duration and the valid time range of the DRX inactivity timer, and the indication information is carried by the downlink control information of format 2-6.

[0019] If the target time window includes the DRX duration, or the target time window includes the DRX duration and the valid time range of the DRX inactivity timer, the downlink control information in format 2-6 defined in the existing communication protocol can be used to carry the indication information. For example, an additional bit is added to the downlink control information in format 2-6 to indicate whether to monitor the target low-power wake-up signal. As a result, the solution in this embodiment can reuse the downlink control information in format 2-6 defined in the existing communication protocol, while being compatible with the existing communication protocol without requiring major changes to the existing communication protocol.

[0020] Optionally, the terminal device may further obtain second configuration information; the second configuration information is used to configure a second monitoring opportunity, and the second monitoring opportunity is used to monitor the target low-power wake-up signal.

[0021] The network device can configure a second monitoring opportunity for the terminal device through the second configuration information. The terminal device determines the second monitoring opportunity based on the second configuration information, and can monitor the target low-power wake-up signal at the second monitoring opportunity.

[0022] Optionally, the second configuration information includes low-power wake-up signal configuration parameters; the low-power wake-up signal configuration parameters include at least one of the following: the time domain starting position of the second listening opportunity, the number of symbols occupied by the second listening opportunity, and the period of the second listening opportunity.

[0023] Optionally, the terminal device may also determine the target PDCCH monitoring opportunity or the target PDCCH monitoring window based on the time domain position of the second monitoring opportunity.

[0024] After the terminal device detects the target low-power wake-up signal at the second listening opportunity, it can determine the PDCCH listening opportunity or the target PDCCH listening window based on the time domain position of the second listening opportunity, thereby waking up the main receiver. The main receiver of the terminal device performs PDCCH monitoring at the target PDCCH listening opportunity or the target PDCCH listening window.

[0025] Optionally, the target PDCCH listening opportunity includes: the first PDCCH listening opportunity after the time domain end position of the second listening opportunity is delayed by X time units. The time domain starting position of the target PDCCH listening window is: the time domain starting position of the first PDCCH listening opportunity after the time domain end position of the second listening opportunity is delayed by X time units; the time length of the target PDCCH listening window is pre-configured.

[0026] Optionally, if the indication information indicates to start PDCCH monitoring within the target time window, the target low-power wake-up signal is monitored within the target time window, otherwise, the target low-power wake-up signal is not monitored within the target time window; if the indication information indicates not to start PDCCH monitoring within the target time window, the target low-power wake-up signal is monitored within the target time window, otherwise, the target low-power wake-up signal is not monitored within the target time window.

[0027] Optionally, the indication information includes a target low-power wake-up signal monitoring trigger indication field. If the target low-power wake-up signal monitoring trigger indication field indicates to monitor the target low-power wake-up signal, the target low-power wake-up signal is monitored within the target time window; if the target low-power wake-up signal monitoring trigger indication field indicates not to monitor the target low-power wake-up signal, the target low-power wake-up signal is not monitored within the target time window.

[0028] The terminal device can monitor the target low-power wake-up signal within the target time window based on explicit indication information. The terminal device can also determine whether to monitor the target low-power wake-up signal within the target time window based on implicit indication information, such as preset rules.

[0029] In the second aspect, the present invention also provides another monitoring method, including: sending indication information, wherein the indication information indicates whether the terminal device monitors the target low-power wake-up signal within the target time window, or the indication information indicates not to monitor the target low-power wake-up signal within the target time window; the target low-power wake-up signal is used to indicate whether the terminal device monitors PDCCH.

[0030] Optionally, the target time window includes at least one of the following: a discontinuous reception DRX duration, a valid time range of the DRX duration and a DRX inactivation timer, and an activation time window for monitoring the PDCCH.

[0031] Optionally, the network device may send a first low-power wake-up signal, and the first low-power wake-up signal carries the indication information.

[0050] When the main receiver has no business transmission or data scheduling, the main receiver can enter a sleep state (deep sleep / light sleep / micro sleep) and does not perform PDCCH monitoring activities. When there is a business transmission demand or data scheduling demand, the terminal device needs to wake up the main receiver. In the prior art, when the main receiver is in a sleep state (deep sleep / light sleep / micro sleep), the low-power receiver of the terminal device can receive a low-power wake-up signal and determine whether to wake up the main receiver to perform PDCCH monitoring based on the received low-power wake-up signal.

[0051] How to trigger and monitor low-power wake-up signals in the RRC connected state and how to monitor low-power wake-up signals to achieve energy saving are urgent issues to be solved.

[0052] In an embodiment of the present invention, the terminal device determines to monitor the target low-power wake-up signal within the target time window based on the indication information, or determines not to monitor the target low-power wake-up signal within the target time window. If the terminal device determines to monitor the target low-power wake-up signal within the target time window, it starts monitoring the target low-power wake-up signal. Otherwise, the terminal device does not monitor the target low-power wake-up signal within the target time window. In this way, unnecessary monitoring of low-power wake-up signals can be avoided, further saving the power consumption of the terminal device.

[0053] In order to make the above-mentioned objects, features and beneficial effects of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0054] The terminal device described in the embodiments of the present application is a device with wireless communication capabilities, and may also be referred to as a terminal, mobile station (MS), mobile terminal (MT), access terminal equipment, vehicle-mounted terminal equipment, industrial control terminal equipment, user equipment (UE) unit, UE station, mobile station, remote station, remote terminal equipment, mobile device, wireless communication device, UE agent, or UE device.

[0055] In the embodiment of the present application, a network device is a device that provides wireless communication functions for a terminal device, and may also be referred to as a radio access network (RAN) device, an access network element, an access network device, etc. The network device may support at least one wireless communication technology, such as LTE, NR, etc. For example, the network device includes, but is not limited to: a next-generation base station (gNB) in 5G, an evolved node B (eNB), a radio network controller (RNC), a node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., home evolved node B, or home node B, HNB), a baseband unit (BBU), a transmitting and receiving point (TRP), a transmitting point (TP), a mobile switching center, etc. The network device may also be a wireless controller, a centralized unit (CU), and / or a distributed unit (DU) in a cloud radio access network (CRAN) scenario, or the network device may be a relay station, an access point, an on-board device, a terminal device, a wearable device, a network device in future mobile communications, or a network device in a future evolved PLMN. In some embodiments, the network device may also be a device that provides wireless communication functions for a terminal device, such as a chip system. For example, the chip system may include a chip and may also include other discrete devices.

[0056] In some embodiments, the network device may also communicate with an Internet Protocol (IP) network, such as the Internet, a private IP network, or other data networks.

[0057] The embodiment of the present invention provides a monitoring method, referring to Figure 1 , the following is a detailed description through specific steps.

[0058] In a specific implementation, the monitoring method provided in steps 100 to 101 below can be executed by a chip (such as a baseband chip) with data processing capabilities in the terminal device, or by a chip module (such as a baseband chip module) with data processing capabilities in the terminal device, or by the terminal device. The following description takes the monitoring method provided in steps 100 to 101 performed by the terminal device as an example.

[0059] Step 101: Based on the indication information, determine to monitor the target low power consumption wake-up signal within the target time window, or determine not to monitor the target low power consumption wake-up signal within the target time window.

[0060] In the embodiment of the present invention, before executing step 101, the terminal device may further execute the following step 100:

[0061] Step 100: Obtain instruction information.

[0062] In an embodiment of the present invention, a network device may send indication information to a terminal device, the indication information being used to instruct the terminal device whether to monitor a target low-power wake-up signal within a target time window. The above-mentioned indication of whether the terminal device monitors a target low-power wake-up signal within a target time window includes the following two situations: the indication information instructs the terminal device to monitor the target low-power wake-up signal within the target time window, and the indication information instructs the terminal device not to monitor the target low-power wake-up signal within the target time window.

[0063] The terminal device receives the indication information and determines whether to monitor the target low-power wake-up signal within the target time window. Specifically, if the indication information instructs the terminal device to monitor the low-power wake-up signal within the target time window, the terminal device can monitor the target low-power wake-up signal within the target time window. If the indication information instructs the terminal device not to monitor the low-power wake-up signal within the target time window, the terminal device determines not to monitor the target low-power wake-up signal within the target time window. The target low-power wake-up signal can be used to indicate whether the terminal device monitors the PDCCH.

[0064] In a specific implementation, the terminal device can determine whether to monitor the target low-power wake-up signal within the target time window based on the content carried by the indication information. In other words, after the terminal device obtains the indication information, it needs to further obtain the content carried by the indication information to further determine whether to monitor the target low-power wake-up signal within the target time window.

[0065] Specifically, the indication information may include an indication field. If the value of the indication field is a first value, the indication information may directly instruct the terminal device to monitor the target low-power wake-up signal within the target time window; if the value of the indication field is a second value, the indication information may instruct the terminal device not to monitor the target low-power wake-up signal within the target time window.

[0066] For example, the length of the indication field is 1 bit. When the value of the indication field is 1, it instructs the terminal device to monitor the target low-power wake-up signal within the target time window; when the value of the indication field is 0, it instructs the terminal device not to monitor the target low-power wake-up signal within the target time window.

[0067] In some embodiments, the indication information may also directly instruct the terminal device to monitor the target low-power wake-up signal within the target time window. In other words, upon receiving the indication information, the terminal device may determine to monitor the target low-power wake-up signal within the target time window.

[0068] For example, when a terminal device receives indication information in a specific format, it determines to monitor the target low-power wake-up signal within the target time window. The indication information in the specific format described above can be of a different information type than that defined in existing communication protocols. In other words, a specific information type can be defined specifically for transmitting the indication information provided in the embodiments of the present invention.

[0069] For another example, the indication information is carried by the information defined in the existing communication protocol (such as DCI information, etc.) and exists in the form of an indication field. The length of the indication field can be 1 bit or other bits. When the terminal device receives this information, it can determine to monitor the target low-power wake-up signal within the target time window. In other words, the transmission of indication information can reuse the information type defined in the existing communication protocol, and the information type defined in the existing communication protocol can be changed to be compatible with the existing communication protocol.

[0070] In specific applications, the terminal device may include a main receiver and a low-power receiver. The main receiver, which can also be referred to as the main RF receiving module, main RF receiving module, main RF receiver, first RF receiving module, first RF receiver, etc., is used for normal data communication of the terminal device. The low-power receiver, which can also be referred to as the low-power RF receiving module, low-power RF receiving module, low-power RF receiver, auxiliary RF receiving module, auxiliary RF receiver, second RF receiving module, second RF receiver, etc., is used to receive low-power wake-up signals. Compared to the main receiver, the low-power receiver operates with lower power.

[0071] In the following embodiments, the low-power receiver of the terminal device is used to monitor and receive the low-power wake-up signal, and the main receiver of the terminal device is used to monitor and receive the PDCCH.

[0072] In an embodiment of the present invention, if the indication information instructs the terminal device to monitor the target low-power wake-up signal within the target time window, the terminal device may monitor the target low-power wake-up signal within the target time window through the low-power receiver. The target low-power wake-up signal may instruct the main receiver of the terminal device to monitor the PDCCH.

[0073] In an embodiment of the present invention, the indication information may be carried by a first low-power wake-up signal. The terminal device may monitor the first low-power wake-up signal at a first monitoring opportunity and monitor the target low-power wake-up signal at a second monitoring opportunity. The first monitoring opportunity may be outside the target time window in the time domain, that is, the first monitoring opportunity and the target time window have no intersection in the time domain; the second monitoring opportunity may be within the target time window in the time domain.

[0074] In a specific implementation, in the time domain, the first listening opportunity may be located before the target time window. The number of the first listening opportunities may be one or more, and the number of the second listening opportunities may also be one or more.

[0075] In the embodiment of the present invention, the monitoring opportunity is used to monitor the low-power wake-up signal. Specifically, the monitoring opportunity can be a time-frequency resource, which can occupy one or more consecutive symbols in the time domain and can include one or more physical resource blocks in the frequency domain.

[0076] Reference Figure 2 , a schematic diagram of the timing relationship between a low-power wake-up signal and a target time window in an embodiment of the present invention is given. Figure 2 In the example, the first listening opportunity is located before the target time window, and the second listening opportunity is located within the target time window. The number of the first listening opportunities is 4, and the number of the second listening opportunities is 4.

[0077] In a specific implementation, the network device may configure and send low-power wake-up signal resource configuration information (hereinafter referred to as the first configuration information) for the terminal device. The network device may send the first configuration information to the terminal device through high-layer signaling. The terminal device may determine the resource location of the listening opportunity for monitoring the low-power wake-up signal based on the first configuration information, and monitor the low-power wake-up signal at the corresponding resource location. The high-layer signaling may include RRC signaling, Media Access Control (MAC) control element (CE), etc.

[0078] In some embodiments, the first configuration information can be used to configure the resource locations of the first listening opportunity and the second listening opportunity. Based on the first configuration information, the terminal device determines the resource locations of the first listening opportunity and the second listening opportunity, and listens for the first low-power wake-up signal at the resource location corresponding to the first listening opportunity, and listens for the target low-power wake-up signal at the resource location corresponding to the second listening opportunity.

[0079] In a specific implementation, the first configuration information may include a first configuration parameter and a second configuration parameter. The terminal device determines the first monitoring opportunity and the second monitoring opportunity based on the first configuration parameter and the second configuration parameter, respectively.

[0080] The first configuration parameter may include at least one of the following: a time domain starting position of the first listening opportunity, the number of symbols occupied by the first listening opportunity, a period of the first listening opportunity, etc. The second configuration parameter may include at least one of the following: a time domain starting position of the second listening opportunity, the number of symbols occupied by the second listening opportunity, a period of the second listening opportunity, etc.

[0081] The terminal device can determine the time domain position of the first monitoring opportunity based on the first configuration parameter and the time domain starting position of the target time window. The terminal device can determine the second monitoring opportunity based on the second configuration parameter.

[0082] In a specific implementation, the second listening opportunity is located within the target time window. Therefore, within the target time window, the second listening opportunity can be periodic. Therefore, by configuring the time domain starting position of the second listening opportunity, the number of symbols occupied by the second listening opportunity, and the period of the second listening opportunity, the distribution of the second listening opportunities within the target time window can be determined.

[0083] The time domain starting position of the first listening opportunity may include a starting time slot of the first listening opportunity, a starting subframe of the first listening opportunity, a starting symbol of the first listening opportunity, etc. For example, the starting time slot of the first listening opportunity is time slot 1, and the starting symbol is symbol 0 in time slot 1.

[0084] The time domain starting position of the second listening opportunity may include a starting time slot of the second listening opportunity, a starting subframe of the second listening opportunity, a starting symbol of the second listening opportunity, etc. For example, the starting time slot of the second listening opportunity is time slot 2, and the starting symbol is symbol 0 in time slot 2.

[0085] Combine Figure 2 , the terminal device can determine the low-power wake-up signal monitoring timing based on the low-power wake-up signal monitoring timing configuration parameters, and the low-power wake-up signal monitoring timing is periodic. The terminal device can divide the determined low-power wake-up signal monitoring timing into a first monitoring timing and a second monitoring timing based on the timing relationship between the low-power wake-up signal monitoring timing and the target time window. Specifically, the low-power wake-up signal monitoring timing outside the target time window is the first monitoring timing; the low-power wake-up signal monitoring timing within the target time window is the second monitoring timing.

[0086] In a specific implementation, the first configuration parameter and the second configuration parameter may be the same. In other words, the network device may be configured with a common configuration parameter, and the terminal device may determine the first monitoring opportunity and the second monitoring opportunity based on the common configuration parameter.

[0087] In other embodiments, the first configuration parameter and the second configuration parameter may also be different. The terminal device may determine the first monitoring opportunity based on the first configuration parameter; and the terminal device may determine the second monitoring opportunity based on the second configuration parameter.

[0088] The first configuration parameter is different from the second configuration parameter, which may include any of the following situations: the period of the first listening opportunity is different from the period of the second listening opportunity, the number of symbols occupied by the first listening opportunity is different from the number of symbols occupied by the second listening opportunity, and the time domain starting position of the first listening opportunity is different from the time domain starting position of the second listening opportunity.

[0089] For example, the period in the first configuration parameter is different from the period in the second configuration parameter, and the period of the first monitoring opportunity is greater than the period of the second monitoring opportunity.

[0090] That is, the network device configures the terminal device with a first configuration parameter specifically for determining the first monitoring opportunity and a second configuration parameter specifically for determining the second monitoring opportunity. Thus, the terminal device determines the first monitoring opportunity and the second monitoring opportunity independently of each other.

[0091] In some embodiments, the first configuration parameters include: a time domain start position of the first listening opportunity, a number of symbols occupied by the first listening opportunity, and a period of the first listening opportunity. The time domain end position of the first listening opportunity can be determined based on the time domain start position of the target time window. Specifically, the time domain end position of the first listening opportunity can be before the target time window, that is, the time domain end position of the last listening opportunity before the target time window.

[0092] For example, the first configuration parameters include: a time domain start position of T1, a number of occupied symbols of 2, and a period of 4 time slots. Based on the time domain start position of the target time window, the time domain end position of the last listening opportunity before the target time window is determined to be T2. Thus, the time domain start position of the first listening opportunity is determined to be T1, the time domain end position is determined to be T2, the period is 4 time slots, and each first listening opportunity occupies 2 symbols.

[0093] In some embodiments, the time domain starting position of the first listening opportunity can be determined by the starting wireless frame number and corresponding starting symbol of the first listening opportunity, and the time domain starting position of the second listening opportunity can be determined by the starting wireless frame number and corresponding starting symbol of the second listening opportunity.

[0094] In other embodiments, the time domain starting position of the first listening opportunity can be determined by the starting time slot number and corresponding starting symbol of the first listening opportunity, and the time domain starting position of the second listening opportunity can be determined by the starting time slot number and corresponding starting symbol of the second listening opportunity.

[0095] Reference Figure 3, a schematic diagram of the timing relationship between a low-power wake-up signal and a target time window in an embodiment of the present invention is given. Figure 3 The first listening opportunity is outside the target time window, the second listening opportunity is within the target time window, and the period of the first listening opportunity is greater than the period of the second listening opportunity.

[0096] In a specific implementation, the first configuration parameter may include the offset between the first listening opportunity and the time domain starting position of the target time window; the second configuration parameter can be used to determine the second listening opportunity, and the second configuration parameter includes at least one of the following: the time domain starting position of the second listening opportunity, the number of symbols occupied by the second listening opportunity, and the period of the second listening opportunity.

[0097] In some embodiments, the number of offsets in the first configuration parameter may be N, where N is a positive integer. That is, if the number of offsets in the first configuration parameter is one, one first listening opportunity may be determined; if the number of offsets in the first configuration parameter is two or more, two or more first listening opportunities may be determined.

[0098] In some embodiments, the first configuration parameter may include a time domain starting position of the first listening opportunity, a number of symbols occupied by the first listening opportunity, and a period of the first listening opportunity; the second configuration parameter may include an offset, which may be a time difference between the time domain starting position of the second listening opportunity and the time domain starting position of the target time window. In the time domain, the time domain starting position of the second listening opportunity is located after the time domain starting position of the target time window.

[0099] Reference Figure 4 , a schematic diagram of the timing relationship between another low-power wake-up signal and the target time window in an embodiment of the present invention is given.

[0100] Figure 4 In the example of N=1, the terminal device determines a first monitoring opportunity based on the time domain starting position and offset of the target time window, and determines a second monitoring opportunity within the target time window based on the second configuration parameter.

[0101] The first configuration parameter corresponding to the first low-power wake-up signal includes only an offset, but does not include a corresponding period, a start symbol, etc., which reduces downlink overhead while indicating the first monitoring opportunity.

[0102] In a specific implementation, when the indication information is carried by the first low-power wake-up signal, the meaning represented by the content carried in the first low-power wake-up signal is different from that represented by the target low-power wake-up signal.

[0103] Specifically, the bit in the first low-power wake-up signal can be used to indicate whether the terminal device starts the target time window timer; the bit in the target low-power wake-up signal can be used to indicate whether the terminal device wakes up the main receiver to monitor the PDCCH.

[0104] For example, the first low-power wake-up signal includes 8 bits, each of which is associated with a terminal device. When the value of a certain bit is 1, it indicates that the terminal device corresponding to the bit starts the target time window timer. Starting the target time window timer indicates that the main receiver of the terminal device can perform PDCCH monitoring within the target time window; when the value of the bit is 0, it indicates that the terminal device corresponding to the bit does not need to start the target time window timer.

[0105] The target low-power wake-up signal consists of 8 bits, each associated with a terminal device. When the value of a bit is 1, the terminal device corresponding to that bit wakes up the main receiver to monitor the PDCCH; when the value of the bit is 0, the terminal device corresponding to that bit does not need to wake up the main receiver.

[0106] For another example, the first low-power wake-up signal includes 8 bits, with each two bits associated with a terminal device. When the value of the two bits is 11, it indicates that the corresponding terminal device starts the target time window timer; when the value of the two bits is 00, it indicates that the corresponding terminal device does not need to start the target time window timer.

[0107] The target low-power wake-up signal consists of 8 bits, with each two bits associated with a terminal device. When the value of the two bits is 11, it indicates that the corresponding terminal device wakes up the main receiver to monitor the PDCCH; when the value of the two bits is 00, it indicates that the corresponding terminal device does not need to wake up the main receiver.

[0108] In an embodiment of the present invention, the target time window may include the duration (On-duration) of discontinuous reception (DRX); or, the target time window may include the valid time range of On-duration and DRX inactive timer (hereinafter referred to as inactive timer time range); or, the target time window may include an activation time window for monitoring PDCCH.

[0109] For the specific functions and definitions of the DRX on-duration and inactive timer time range, please refer to the description of DRX in the existing protocol.

[0110] In an embodiment of the present invention, the activation time window may be a periodic time window configured by a network device. The network device may configure the time domain starting position of the activation time window (which may be a starting time slot number or a starting radio frame number, etc.), the window length of the activation time window, and the period of the activation time window. Based on the above configuration, the terminal device may determine the time domain position of the activation time window.

[0111] Alternatively, the terminal device may start the activation time window after receiving the first low-power wake-up signal. The time domain starting position of the activation time window may be determined by the time domain ending position and offset of the first listening opportunity, the window length of the activation time window may be configured by the network device, and the offset may be a preset value or configured by the network device.

[0112] Specifically, the time domain start position of the activation time window may be located after the time domain end position of the first listening opportunity, and the time difference between the activation time window and the time domain end position of the first listening opportunity is the above-mentioned offset.

[0113] For example, the time domain end position of the first monitoring opportunity is T1, and the offset is △, then the time domain start position of the activation time window is T1+△.

[0114] In a specific implementation, if the target time window is On-duration, the first listening opportunity is outside the On-duration and the second listening opportunity is within the On-duration; or, if the target time window is the time range of On-duration and inactive timer, the second listening opportunity is within the time range of On-duration and inactive timer.

[0115] Reference Figure 5 , provides a schematic diagram of the timing relationship between another low-power wake-up signal and the target time window in an embodiment of the present invention.

[0116] If the target time window is an on-duration, then the target time window can also be called a target duration. Figure 5 In the example, the time difference between the time domain starting positions of Duration 1 and Duration 2 is considered the DRX cycle. Duration 2 is the target duration. The first monitoring opportunity is located before Duration 2 and has no intersection with Duration 1. The second monitoring opportunity is located within Duration 2 (also known as the target duration).

[0117] Reference Figure 6 , provides a schematic diagram of the timing relationship between another low-power wake-up signal and the target time window in an embodiment of the present invention.

[0118] Figure 6In the example, there is an offset between the first listening opportunity and the time domain starting position of duration 2. That is, the terminal device can determine the time domain ending position of the first listening opportunity based on the time domain starting position of duration 2 and the offset. The terminal device can determine the time domain starting position of the first listening opportunity based on the preset listening duration of the first listening opportunity. Thus, the terminal device can determine the time domain position of the first listening opportunity.

[0119] Alternatively, the terminal device can determine the time domain end position of the first listening opportunity based on the time domain start position and offset of duration 2. The terminal device obtains the listening duration of the first listening opportunity configured by the network device and determines the time domain start position of the first listening opportunity. Thus, the terminal device can determine the time domain position of the first listening opportunity.

[0120] In a specific implementation, if the target time window is an activation time window, the first monitoring opportunity is outside the activation time window, and the second monitoring opportunity is within the activation time window.

[0121] Reference Figure 7 , provides a schematic diagram of the timing relationship between another low-power wake-up signal and the target time window in an embodiment of the present invention.

[0122] Figure 7 In the example, the first monitoring opportunities are all outside the activation time window, and the second monitoring opportunities are all within the activation time window.

[0123] Reference Figure 8 , provides a schematic diagram of the timing relationship between another low-power wake-up signal and the target time window in an embodiment of the present invention.

[0124] Figure 8 In the example, there is an offset between the first monitoring opportunity and the time domain starting position of the activation time window.

[0125] In a specific implementation, the activation time window may occur non-periodically. Upon receiving the first low-power wake-up signal, the terminal device initiates the activation time window. The terminal device may determine the time domain starting position of the activation time window based on the time domain ending position and offset of the first listening opportunity. The window length of the activation time window may be configured by the network device, and the offset may be a preset value or configured by the network device.

[0126] Continue with Figure 8As an example, the terminal device receives a first low-power wake-up signal at a first listening opportunity and starts the activation time window. The terminal device determines the time domain start position of the activation time window based on the time domain end position and offset of the first listening opportunity. The terminal device determines the time domain end position of the activation time window based on the window length configured by the network device. Thus, by starting the activation time window in response to the first low-power wake-up signal, the activation time window can be enabled to appear on demand.

[0127] In an embodiment of the present invention, the terminal device may also determine whether to monitor the target low-power wake-up signal within the target time window based on a preset rule. The preset rule may be pre-configured in the communication protocol or pre-indicated by the network device.

[0128] In a specific implementation, if the instruction information indicates to start PDCCH monitoring within the target time window, the target low-power wake-up signal can be monitored within the target time window. Otherwise, the terminal device does not monitor the target low-power wake-up signal within the target time window.

[0129] Alternatively, if the indication information indicates not to start PDCCH monitoring within the target time window, the target low-power wake-up signal may be monitored within the target time window. Otherwise, the terminal device does not monitor the target low-power wake-up signal within the target time window.

[0130] In a specific implementation, if the indication information starts PDCCH monitoring within the target time window, it can be further determined whether to monitor the target low-power wake-up signal within the target time window according to the indication of the downlink control information (DCI). Specifically, a new bit can be added to the DCI, and the terminal device determines whether to start monitoring the target low-power wake-up signal according to the value of the new bit.

[0131] In an embodiment of the present invention, if the target time window is On-duration, the indication information can be carried by DCI format 2-6; or, if the target time window is the On-duration and inactive timer time range, the indication information can be carried by DCI format 2-6.

[0132] In a specific implementation, the network device can add an indication field in the DCI format 2-6, and through the value of the newly added indication field, instruct the terminal device to listen to the target low-power wake-up signal during the On-duration; or, the network device can add an indication field in the DCI format 2-6, and through the value of the newly added indication field, instruct the terminal device to listen to the target low-power wake-up signal within the On-duration and inactive timer time range.

[0133] In some embodiments, if the terminal device receives DCI format 2-6, and DCI format 2-6 includes a newly added indication field, it can be determined to monitor the target low-power wake-up signal within the On-duration, or the On-duration and inactive timer time range.

[0134] In other embodiments, if the terminal device receives DCI format 2-6 and DCI format 2-6 includes a newly added indication field, it determines whether to monitor the target low-power wake-up signal during the on-duration period based on the value of the newly added indication field. Alternatively, the terminal device determines whether to monitor the target low-power wake-up signal within the time range of on-duration and inactive timer based on the value of the newly added indication field. DCI format 2-6 can include target low-power wake-up signals of multiple terminal devices.

[0135] For example, the length of the newly added indication field is 1 bit. If the value of the newly added indication field is 1, all terminal devices receiving the DCI format 2-6 are determined to monitor the target low-power wake-up signal within the time range of On-duration and inactive timer; if the value of the newly added bit field is 0, all terminal devices receiving the DCI format 2-6 are determined not to monitor the target low-power wake-up signal within the time range of On-duration and inactive timer.

[0136] For another example, the length of the newly added indication field is M bits, each bit corresponds to a terminal device, and M is a positive integer. If terminal device 1 receives the DCI format 2-6 and detects that the bit value corresponding to terminal device 1 in the newly added indication field is 1, it is determined to monitor the target low-power wake-up signal during the on-duration period; if terminal device 1 detects that the bit value corresponding to terminal device 1 in the newly added indication field is 0, it is determined not to monitor the target low-power wake-up signal during the on-duration period.

[0137] In a specific implementation, if the network device instructs the terminal device through DCI format 2-6 whether to monitor the target low-power wake-up signal within the target time window, the network device may also configure a second monitoring opportunity for the terminal device through the second configuration information. The above-mentioned second configuration information may include at least one of the following: the time domain starting position of the second monitoring opportunity, the number of symbols occupied by the second monitoring opportunity, and the period of the second monitoring opportunity. The terminal device can determine the second monitoring opportunity based on the received second configuration information and monitor the target low-power wake-up signal at the second monitoring opportunity.

[0138] In a specific implementation, the time domain starting position of the second listening opportunity may include a starting time slot of the second listening opportunity, a starting subframe of the second listening opportunity, a starting symbol of the second listening opportunity, etc. For example, the starting time slot of the second listening opportunity is time slot 2, and the starting symbol is symbol 0 in time slot 2.

[0139] In a specific implementation, the second listening opportunity is located within the target time window. Therefore, within the target time window, the second listening opportunity can be periodic. Therefore, by configuring the time domain starting position of the second listening opportunity, the number of symbols occupied by the second listening opportunity, and the period of the second listening opportunity, the distribution of the second listening opportunities within the target time window can be determined.

[0140] Reference Figure 9 , a schematic diagram of the timing relationship between a low-power wake-up signal and a target time window in an embodiment of the present invention is given.

[0141] Figure 9 In the first DCI format 2-6 (i.e. Figure 9 The DCI format 2-6 on the left side of the middle) indicates that the target low power wake-up signal is not monitored during duration 1, and the second DCI format 2-6 (ie Figure 9 The DCI format 2-6 on the right side of the middle indicates monitoring the target low power wake-up signal within duration 2. The second monitoring opportunity is within duration 2. The specific resource location of the second monitoring opportunity within duration 2 is determined by the second configuration information.

[0142] In an embodiment of the present invention, the terminal device may also determine whether to monitor the target low-power wake-up signal within the target time window based on a preset rule.

[0143] In a specific implementation, if DCI format 2-6 indicates that the awakened terminal device monitors PDCCH on-duration, the terminal device can monitor the low-power target wake-up signal on-duration. Otherwise, the terminal device does not monitor the low-power target wake-up signal on-duration.

[0144] Alternatively, if DCI format 2-6 indicates that the terminal device does not monitor the PDCCH in the on-duration period, the terminal device monitors the low-power target wake-up signal in the on-duration period. Otherwise, the terminal device does not monitor the low-power target wake-up signal in the on-duration period.

[0145] In a specific implementation, if DCI format 2-6 indicates that the awakened terminal device monitors PDCCH within the on-duration and inactive timer time range, the terminal device can monitor the low-power target wake-up signal within the on-duration and inactive timer time range. Otherwise, the terminal device does not monitor the low-power target wake-up signal within the on-duration and inactive timer time range.

[0146] Alternatively, if DCI format 2-6 indicates that the terminal device does not monitor the PDCCH within the on-duration and inactive timer time range, the terminal device monitors the low-power target wake-up signal within the on-duration and inactive timer time range. Otherwise, the terminal device does not monitor the low-power target wake-up signal within the on-duration and inactive timer time range.

[0147] Reference Figure 10 , a schematic diagram of the timing relationship between a low-power wake-up signal and a target time window in an embodiment of the present invention is given.

[0148] Figure 10 In the first DCI format 2-6 (i.e. Figure 10 The DCI format 2-6 on the left in the figure instructs the terminal device to wake up the main receiver to receive the PDCCH in duration 1. The second DCI format 2-6 (i.e. Figure 10 The DCI format 2-6 on the right side of the figure indicates that the terminal device does not wake up the main receiver to receive PDCCH during duration 2.

[0149] Reference Figure 11 , a schematic diagram of the timing relationship between a low-power wake-up signal and a target time window in an embodiment of the present invention is given.

[0150] Figure 11 In the first DCI format 2-6 (i.e. Figure 11 The DCI format 2-6 on the left in the figure indicates that the terminal device does not wake up the main receiver to receive the PDCCH during duration 1. The second DCI format 2-6 (i.e. Figure 11 The DCI format 2-6 on the right side of the figure indicates that the terminal device wakes up the main receiver to receive the PDCCH during duration 2.

[0151] If the terminal device determines that the PDCCH for scheduling is received during the On-duration, the terminal device may start the inactive timer.

[0152] In an embodiment of the present invention, the indication information may also carry a target low-power wake-up signal monitoring trigger indication field. The target low-power wake-up signal monitoring trigger indication field is used to indicate whether the terminal device monitors the target low-power wake-up signal. If the target low-power wake-up signal monitoring trigger indication field indicates monitoring the target low-power wake-up signal, the terminal device monitors the target low-power wake-up signal within the target time window; otherwise, if the target low-power wake-up signal monitoring trigger indication field indicates not monitoring the target low-power wake-up signal, the terminal device does not monitor the target low-power wake-up signal within the target time window.

[0153] In an embodiment of the present invention, after determining the second monitoring opportunity, the terminal device may determine a target PDCCH monitoring opportunity based on the time domain position of the second monitoring opportunity. Alternatively, the terminal device may determine a target PDCCH monitoring window based on the time domain position of the second monitoring opportunity.

[0154] In a specific implementation, based on the time domain end position of the second monitoring opportunity, the first PDCCH monitoring opportunity after X time units can be postponed as the target PDCCH monitoring opportunity. The time unit can include any one of a time slot, a subframe, a frame, a PDCCH monitoring opportunity period, milliseconds, etc.

[0155] For example, the time unit is a PDCCH monitoring period. The target PDCCH monitoring opportunity is located after the time domain end position of the second monitoring opportunity, and the time domain end position of the target PDCCH monitoring opportunity differs from the time domain end position of the second monitoring opportunity by two PDCCH monitoring period periods.

[0156] like Figure 12 As shown, a schematic diagram of the timing relationship between a second monitoring opportunity and a PDCCH monitoring opportunity in an embodiment of the present invention is given.

[0157] Figure 12 In the example, the target PDCCH monitoring opportunity is: the time domain end position of the second monitoring opportunity, and the first PDCCH monitoring opportunity after being postponed by 2 PDCCH monitoring opportunity periods (time offset).

[0158] In a specific implementation, based on the time domain end position of the second monitoring opportunity, M consecutive PDCCH monitoring opportunities after X time units can be postponed as the target PDCCH monitoring opportunity. The time domain starting position of the target PDCCH monitoring opportunity is: the first PDCCH monitoring opportunity after the time domain end position of the second monitoring opportunity is postponed by X time units.

[0159] like Figure 13 As shown, a schematic diagram of the timing relationship between another second monitoring opportunity and the PDCCH monitoring opportunity in an embodiment of the present invention is given.

[0160] Figure 13 In the example, the target PDCCH monitoring opportunity is: the time domain end position of the second monitoring opportunity, and three consecutive PDCCH monitoring opportunities after the period (time offset) of two PDCCH monitoring opportunities is postponed.

[0161] In a specific implementation, the values ​​of X and M may be configured by a network device and delivered by the network device through Radio Resource Control (RRC) signaling.

[0162] In a specific implementation, the specific value of X may be related to the capabilities of the terminal device. Furthermore, the specific value of X may be related to the state transition duration of the terminal device, which is the time required for the terminal device's main receiver to transition from a sleep state to an awake state. For different sleep states, the corresponding state awakening durations may be the same or different.

[0163] For example, the state transition time of the main receiver of the terminal device from the deep sleep state to the awake state is T1, the state transition time from the light sleep state to the awake state is T2, and the state transition time from the micro sleep state to the awake state is T3, T1>T2>T3.

[0164] The terminal device can report the state transition durations corresponding to different sleep states to the network device based on its own capabilities. The network device can configure the corresponding value of X based on the state transition durations corresponding to different sleep states reported by the terminal device.

[0165] An embodiment of the present invention also provides another monitoring method, including: sending indication information, the indication information indicating whether the terminal device monitors the target low-power wake-up signal within the target time window, the target low-power wake-up signal is used to indicate whether the terminal device monitors PDCCH.

[0166] In the embodiment of the present invention, the monitoring method performed by the above network device may correspond to the description of the network device in the above steps 100 to 101, which will not be described in detail here.

[0167] Reference Figure 14 , a monitoring device 14 in an embodiment of the present invention is provided, including: a processing unit 141, used to determine, based on indication information, whether to monitor a target low-power wake-up signal within a target time window, or to determine not to monitor a target low-power wake-up signal within the target time window; the target low-power wake-up signal is used to indicate whether a terminal device monitors a PDCCH.
