[0039] For example, Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of this application. Figure 1 As shown, the communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or a communication terminal, terminal). The network device 110 can provide communication coverage for a specific geographical area and can communicate with terminal devices located within that coverage area.

[0040] Figure 1 An exemplary diagram shows a network device and two terminal devices. In some embodiments of this application, the communication system 100 may include multiple network devices and each network device may include other numbers of terminal devices within its coverage area. This application does not limit the scope of the embodiments.

[0041] In some embodiments of this application, Figure 1 The wireless communication system shown may also include other network entities such as a mobility management entity (MME) and an access and mobility management function (AMF), but this application does not limit this.

[0042] It should be understood that devices with communication functions in the network / system of this application embodiment can be referred to as communication devices. Figure 1 Taking the communication system 100 shown as an example, the communication equipment may include a network device 110 and a terminal device 120 with communication functions. The network device 110 and the terminal device 120 can be the specific devices described above, which will not be repeated here. The communication equipment may also include other devices in the communication system 100, such as network controllers, mobility management entities, and other network entities. This application embodiment does not limit this. The following will first introduce some concepts involved in this application. It should be understood that the following related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, and they all fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0043] In related technologies, discontinuous transmission (DTX) and discontinuous reception (DRX) techniques have been introduced to achieve energy saving in terminal devices. These two techniques effectively reduce power consumption by periodically controlling the terminal device to switch between active and sleep states. However, during the active period of DRX, the terminal device needs to listen to the physical downlink control channel (PDCCH) for blind detection of downlink control information (DCI). If network devices do not send DCI to schedule terminal devices for extended periods, the terminal device waking up to listen to the PDCCH during the active period of DRX in each cycle will generate significant energy consumption.

[0044] To address this issue, related technologies have introduced downlink wake-up signal (DL-WUS) technology. DL-WUS is used to indicate whether the terminal device should wake up to listen to the PDCCH during the DRX active period after the signal, or remain asleep for a period of time after the signal without listening to the PDCCH.

[0045] When a terminal device needs to wake up to listen to the PDCCH during the DRX active period, the base station will send a DL-WUS to notify the terminal device in advance. When the terminal device does not receive the DL-WUS, it will remain in a sleep state or a low-power state, meaning it does not need to listen to the DCI during subsequent PDCCH listening opportunities.

[0046] However, even with the introduction of DL-WUS technology, terminal devices still consume significant power to monitor DL-WUS. To further reduce the power consumption of terminal devices monitoring the PDCCH, a low-power wake-up signal (LP-WUS) design scheme has been proposed. This design scheme uses a lower-power receiver, namely a low-power-wake upreceiver (LP-WUR), which can operate independently of the main radio frequency of the communication system. For connected terminal devices, they enter sleep mode (or low-power mode) according to the network device configuration. At this time, the LP-WUR enters the working state to search for LP-WUS, while the main radio frequency of the communication system can remain off, thereby achieving ultra-deep sleep of the terminal device's main radio frequency for a more extreme energy-saving state.

[0047] In addition, to maintain the main radio frequency in a deep sleep state, network devices can be configured with a periodic low power-synchronization signal (LP-SS). The LP-WUR can perform radio resource management (RRM) measurements and acquire time-frequency synchronization based on the LP-SS to receive the LP-WUS and subsequent paging messages.

[0048] Under the aforementioned LP-WUS mechanism, the receiver on the main radio frequency of the terminal device starts working after receiving LP-WUS signals, and begins listening for the PDCCH. However, in some situations, the terminal device may miss the DCI signal. For example, when the terminal device is in power-saving mode, it may miss the DCI signal used to wake up the terminal device, resulting in the UE missing the DCI signal. Another example is when the radio channel quality deteriorates, the terminal device may miss the DCI signal used to indicate the handover of the BWP, causing all subsequent DCI signals to be unreceived.

[0049] In some scenarios, after a terminal device misses a DCI (Distributed Communication Interface) signal, it enters a power-saving mode, such as when the main radio frequency (RF) enters a deep sleep state. Because the network device is unaware of the missed DCI, it assumes the terminal device's RF is still active and continues to send DCI signals to the RF receiver. At this point, the terminal device cannot receive subsequent DCI signals, resulting in a prolonged loss of communication between the terminal device and the network device, increasing the communication latency of the communication system.

[0050] To address the aforementioned issues, in this embodiment, the terminal device sends a first feedback message to the network device to indicate whether control information has been detected. This way, when the terminal device misses a control message, the network device can quickly obtain this information through the first feedback message, enabling timely control of the terminal device (e.g., resending the control information), reducing communication latency and improving communication quality.

[0051] The embodiments of this application will be described in detail below.

[0052] Figure 2 This is a flowchart illustrating a communication method provided in an embodiment of this application.

[0053] See Figure 2 In step S210, in response to receiving the first wake-up signal sent by the network device, the terminal device begins to listen for control information. This control information can also be referred to as DCI.

[0054] The first wake-up signal is used to wake up the terminal device, such as waking it from sleep mode or low-power mode; or, in other words, the first wake-up signal is used to wake up the main radio frequency of the terminal device. In some implementations, the first wake-up signal can be LP-WUS.

[0055] In some implementations, the terminal device can receive a first wake-up signal based on the first radio frequency module, and the terminal device can receive control information based on the second radio frequency module.

[0056] The operating power of the first radio frequency module is less than that of the second radio frequency module. For example, the first radio frequency module can be the receiver of the main radio frequency of the terminal device, and the second receiver module can be the low-power wake-up receiver (LP-WUR) of the terminal device.

[0057] For example, the terminal device can enter sleep mode (or low-power mode) according to the network device's configuration. In this mode, the LP-WUR enters the working state to search for the LP-WUS, while the main radio frequency of the communication system can remain off. When the LP-WUR finds the LP-WUS, the receiver of the main radio frequency starts working and listens for the PDCCH. Furthermore, the terminal device can inform the network device of the result of the listening control information by sending a first feedback message.

[0058] In some implementations, the terminal device can listen for control information based on a search space. This search space can be a public search space or a search space specific to the terminal device.

[0059] There are several ways to determine the temporal location of the search space. In some implementations, the temporal location of the search space can be determined based on the first indication information sent by the network device. Alternatively, in other implementations, the temporal location of the search space can be predefined by the protocol. These two methods will be described in detail below.

[0060] Method 1: The temporal location of the search space is determined based on the first indication information. This determination method can include three specific implementation methods, which will be described in detail below.

[0061] Implementation method 1: The temporal location of the search space can be determined based on the first parameter, and the first indication information can indicate or contain the first parameter.

[0062] The first parameter can be a parameter in the first formula, which is used to determine the temporal location of the search space, such as the starting temporal location of the search space. For example, the first formula can be the period formula in DRX mode. For example, the first formula can satisfy: (SFN×N+timeslot number) mod (period) = offset. Where SFN (system frame number) represents the system frame number, N represents the unit conversion factor, timeslot number represents the timeslot number, period represents the configuration period of temporal resources, and offset represents the timeslot offset.

[0063] In other words, the terminal device can start listening to control information at a time domain position that satisfies the first formula, such as (SFN×N+timeslot number) mod (period) = offset.

[0064] The first parameter can be any one or more parameters in the first formula. For example, the first parameter can be period or SFN information, meaning the network device can indicate the period or SFN information in the first formula through the first indication information. As another example, the first parameter can be an offset, meaning the network device can indicate the offset information in the first formula through the first indication information. The UE calculates the temporal location of the search space, such as the starting temporal location, based on the first parameter in the first indication information and the first formula. Directly indicating the parameter value in the first formula through the first indication information can help the terminal device determine the temporal location of the search space when the terminal device loses synchronization with the network device.

[0065] Implementation method 2: The first indication information can include information related to the temporal location of the search space.

[0066] In some scenarios, information related to the temporal location of the search space may include one or more of the following: the period of the search space, the starting temporal location of the search space within the period, the number of time units occupied by the search space, the temporal offset, the identification information of the configuration related to the search space, the identification information of the control resource set associated with the search space, and the type of the search space.

[0067] It should be understood that the identification information of the above-mentioned search space related configuration can be, for example, a specific ID value of the search space configuration information. For example, the terminal device can determine the temporal location of the target search space from multiple pre-configured search spaces based on this ID value.

[0068] In some implementations, the search space time-domain configuration information can be a terminal device-specific configuration in the BWP configuration, or it can be a common configuration in the BWP configuration.

[0069] The type of search space may include, for example, whether the search space is a public search space or a terminal device-specific search space, and / or, the format type of the DCI being listened to by the terminal device.

[0070] For example, the first indication information may include one or more of the following: monitoring slot period and offset, monitoring symbols within slot, and monitoring duration.

[0071] Alternatively, in other scenarios, information related to the temporal location of the search space may include a temporal reference point, and the temporal location of the search space (such as the start or end temporal location) may be determined based on this temporal reference point.

[0072] In some implementations, the aforementioned time-domain reference point may be the start time-domain position or the end time-domain position of the time-domain resource of the first wake-up signal, or the time-domain reference point may be the start time-domain position or the end time-domain position of the time-domain resource where the first indication information is located.

[0073] In some implementations, the aforementioned time-domain reference point can also be predefined by the protocol.

[0074] It should be understood that the start time-domain position mentioned in this document may include the time slot in which the start time-domain position is located, and / or the position of the start symbol within the time slot in which the start time-domain position is located. The end time-domain position mentioned in this document may include the time slot in which the end time-domain position is located, and / or the position of the end symbol within the time slot in which the end time-domain position is located.

[0075] For implementation method 2, the terminal device can update the relevant information of the temporal location of the search space according to the first instruction information.

[0076] Implementation method 3: The first indication information can indicate relevant information about the temporal location of the search space.

[0077] In some implementations, the first configuration information sent by the network device may include information related to the temporal location of the search space, and the first indication information may be used to indicate the first configuration information. For example, the first configuration information may include multiple candidate configuration information, and the first indication information may indicate the target configuration information from the multiple candidate configuration information.

[0078] In some scenarios, the first configuration information may include one or more of the following: the period of the search space, the starting time domain position of the search space in the period, the number of time units occupied by the search space, the time domain offset, the identification information of the configuration related to the search space, the identification information of the control resource set associated with the search space, and the type of the search space.

[0079] Alternatively, in other scenarios, the first configuration information may include a time-domain reference point, and the time-domain location of the search space (such as the start time-domain location or the end time-domain location) may be determined based on this time-domain reference point.

[0080] In some implementations, the aforementioned time-domain reference point can be the start or end time-domain position of the time-domain resource of the first wake-up signal, or it can be the start or end time-domain position of the time-domain resource where the first indication information is located. In some implementations, the aforementioned time-domain reference point can also be predefined by the protocol.

[0081] For example, the first configuration information may include multiple sets of time-domain location-related parameters, such as {monitoringSlotPeriodicityAndOffset, monitoringSymbolsWithinSlot, duration}. The network device can indicate one of the sets {monitoringSlotPeriodicityAndOffset, monitoringSymbolsWithinSlot, duration} by sending first indication information (such as carried by LP-WUS). For example, the first indication information may indicate the index value or order of a set of related parameters. For instance, if the indication value of the first indication information is "0", it indicates that the time-domain location of the search space is determined using the first set of related parameters.

[0082] For example, the first configuration information may include multiple sets of time-domain reference points, and the network device indicates one of the sets of time-domain reference points by sending the first indication information.

[0083] This application does not specifically limit the method of carrying the first indication information. In some implementations, the first indication information may be carried in the first wake-up signal.

[0084] For example, the first wake-up signal may include a first parameter. Exemplarily, the LP-WUS sent by the network device may include SFN information.

[0085] For example, the first wake-up signal may include information related to the temporal location of the search space. For instance, the LP-WUS sent by the network device may include information related to the temporal location of the search space.

[0086] For example, the first wake-up signal may include an indication value of the first configuration information, such as identification information related to search space configuration. For instance, the LP-WUS sent by the network device may include identification information related to search space configuration. In other implementations, the first indication information may be carried within the first configuration information; in other words, the first indication information may be pre-configured by the network device for the terminal device.

[0087] Taking the first instruction information containing information related to the temporal location of the search space as an example, the network device can pre-configure the information related to the temporal location of the search space to the terminal device through the first configuration information.

[0088] Taking the first instruction information containing a time domain reference point as an example, the network device can pre-configure the time domain reference point to the terminal device through the first configuration information.

[0089] In some implementations, the network device can send first configuration information (including first indication information) via first higher-layer signaling. For example, the network device can configure the first configuration information for the terminal device via RRC signaling, such as RRC signaling specific to the terminal device. Alternatively, the network device can configure the first configuration information for the terminal device via broadcast information. For example, the network device can configure the first configuration information for the terminal device via SIB1. Or, the network device can configure the first configuration information for the terminal device via a first wake-up signal (such as LP-WUS). Alternatively, LP-WUS may contain identification information indicating the configuration.

[0090] Method 2: The temporal location of the search space is predefined by the protocol. This determination method may include two predefined specific implementation methods of the protocol.

[0091] Implementation method 1: The temporal location of the search space can be determined based on the first parameter, which can be predefined through the protocol.

[0092] The first parameter can be a parameter in the first periodic formula, which determines the temporal location of the search space, such as the starting temporal location. For example, the first periodic formula can be the periodic formula in DRX mode. A detailed description of the first periodic formula and the first parameter can be found above.

[0093] Implementation Method 2: Information related to the temporal location of the search space can be predefined through the protocol.

[0094] In some scenarios, information related to the temporal location of the search space may include one or more of the following: the period of the search space, the starting temporal location of the search space within the period, the number of time units occupied by the search space, the temporal offset, the identification information of the configuration related to the search space, the identification information of the control resource set associated with the search space, and the type of the search space.

[0095] Alternatively, in other scenarios, information related to the temporal location of the search space may include a temporal reference point, upon which the temporal location of the search space (such as the start or end temporal location) can be determined. A detailed description of information related to the temporal location of the search space can be found above.

[0096] See also Figure 2 In step S220, the terminal device sends a first feedback message to the network device. This first feedback message is used to indicate whether the terminal device has detected control information.

[0097] As mentioned above, in related technologies, if the terminal device fails to detect control information, it may cause the terminal device and the network device to lose contact for a long time, increasing the communication latency of the communication system.

[0098] In this embodiment, the terminal device sends a first feedback message to the network device to indicate whether control information has been detected. This way, when the terminal device misses a control message, the network device can quickly obtain this information through the first feedback message, and thus promptly control the terminal device (e.g., by resending the control information), reducing communication latency and improving communication quality.

[0099] Furthermore, the execution of step S220 may include: the terminal device sending first feedback information on the first time domain resource and / or the first frequency domain resource. The determination methods for the first time domain resource and the first frequency domain resource implemented in this application will be described in detail below.

[0100] First Time Domain Resources The first time-domain resource can be determined based on relevant information of the first time-domain resource. In some implementations, the relevant information of the first time-domain resource may include one or more of the following: the start time-domain position of the first time-domain resource, the end time-domain position of the first time-domain resource, the first time-domain offset, the duration of the first time-domain resource, and the period of the first time-domain resource.

[0101] In some implementations, the first time-domain resource can be associated with a search space and / or a first time window; in other words, the first time-domain resource can be determined or configured based on the search space and / or the first time window. Here, the search space and / or the first time window are used to monitor control information.

[0102] It should be understood that the first time window mentioned above can also be replaced with other time-domain related terms. For example, the first time window can be replaced with the duration or active time of listening to control information, or the duration or active time of listening to PDCCH.

[0103] Associating a first time-domain resource with the search space and / or the first time window may include: associating the number of first time-domain resources with the number of search spaces and / or the first time windows; and / or, associating the time-domain location of the first time-domain resource with the time-domain location of the search space and / or the first time window.

[0104] Taking the relevant information of the first time domain resource as the first time domain offset as an example, the first time domain offset can be the time domain offset between the start time domain position or the end time domain position of the first time domain resource and the first time domain reference point.

[0105] For example, the first time-domain reference point may include one or more of the following: the start time-domain position and / or end time-domain position of the search space; the start time-domain position and / or end time-domain position of the first time window; and the start time-domain position and / or end time-domain position of receiving the second indication information.

[0106] The aforementioned second indication information may be indication information sent by the network device to the terminal device, used to indicate relevant information about the first time domain resources. Taking the second indication information carried in DCI or LP-WUS as an example, the first time domain reference point may be the start time domain position and / or end time domain position of DCI or LP-WUS. There are multiple ways to associate the number of first time domain resources with the number of search spaces and / or the number of first time windows. Two association methods provided by embodiments of this application are given below as examples.

[0107] Association Method 1: One first-time domain resource can be associated with M search spaces.

[0108] The association of a first time domain resource with M search spaces can be understood as the configuration of M search spaces or the correspondence of a first time domain resource. In other words, in the time domain, after passing through the time domain positions corresponding to M search spaces, there will be a first time domain resource.

[0109] M can be a positive integer greater than or equal to 1. In some implementations, M can be a fixed value, meaning that each first-temporal resource is associated with a fixed number of search spaces. For example, M can be 1 or 2, meaning that each first-temporal resource can be associated with one or two search spaces.

[0110] For example, such as Figure 3a As shown, in the time domain, a first time domain resource is configured after the search space of each monitoring control information.

[0111] For example, such as Figure 3b As shown, in the time domain, a first time domain resource is configured after every two search spaces of listening control information.

[0112] In some implementations, M can be a variable value, meaning that a first time-domain resource can be associated with a first number of search spaces, and another first time-domain resource can be associated with a second number of search spaces.

[0113] For example, M can be 1 and 3, or M can be 1 and 2.

[0114] For example, such as Figure 3c As shown, in the time domain, a first time domain resource can be configured after the first search space, and another first time domain resource can be configured after the subsequent three search spaces.

[0115] This application does not specifically limit the configuration method of the value of M in the embodiments. For example, the value of M can be predefined by the protocol. Or, the value of M can be configured by the network device, such as through RRC signaling.

[0116] Association Method 2: One first time domain resource is associated with N first time windows.

[0117] The first time window is used to monitor control information. One first time domain resource associated with N first time windows can be understood as N first time windows configuring or corresponding to one first time domain resource. In other words, in the time domain, after passing through the time domain positions corresponding to N first time windows, there will be a first time domain resource.

[0118] N can be a positive integer greater than or equal to 1. In some implementations, a first time-domain resource can be associated with a first time window.

[0119] For example, such as Figure 3d As shown, in the time domain, a first time domain resource is configured after the first time window of each monitoring control message.

[0120] This application does not specifically limit the configuration method of the value of N in the embodiments. For example, the value of N can be predefined by the protocol. Or, the value of N can be configured by the network device, such as through RRC signaling.

[0121] Association Method 3: The first time domain reference point used to determine the start time domain position and / or end time domain position of the first time domain resource is associated with the time domain resources of the search space and / or the first time window.

[0122] In some implementations, the first time-domain reference point can be determined based on its time-domain location in the search space. For example, the first time-domain reference point could be the beginning or end of the search space.

[0123] In other words, the start or end time domain position of the first time domain resource can be determined based on the start or end time domain position of the search space. For example, in the time domain, the start or end time domain position of the first time domain resource can be a time domain position that is a fraction of a time domain offset after the start or end time domain position of the search space.

[0124] In other implementations, the first time-domain reference point can be determined based on the time-domain location of the first time window. For example, the first time-domain reference point can be the start or end time-domain location of the first time window.

[0125] In other words, the start or end time domain position of the first time domain resource can be determined based on the start or end time domain position of the first time window. For example, in the time domain, the start or end time domain position of the first time domain resource can be the time domain position after the start or end time domain position of the first time window, excluding the first time domain offset.

[0126] The preceding text described how to determine the first time domain resource by associating it with the search space and / or the first time window. In some implementations, the first time domain resource may not be associated with the search space and / or the first time window. In other words, the search space and / or the first time window may not be considered when configuring the first time domain resource; for example, the first time domain resource may be a specific time domain resource that can be directly configured by the network device to the terminal device.

[0127] For example, the first time-domain resource can be determined based on the time-domain resource determination of the indication information sent by the network device, such as time-domain resource determination based on LP-WUS.

[0128] It should be understood that the first time-domain resource is not associated with the search space and / or the first time window, which means that the first time-domain resource is not determined or configured based on the search space and / or the first time window. The fact that the first time-domain resource is not associated with the search space and / or the first time window can include: the number of first time-domain resources is not associated with the number of search spaces and / or the first time windows; and / or, the time-domain location of the first time-domain resource is not associated with the time-domain location of the search space and / or the first time window.

[0129] In the above case, since the first time domain resource is not associated with the search space and / or the first time window, in the time domain, the time domain position between the two search spaces can be configured with a first time domain resource or not.

[0130] For example, such as Figure 3c As shown, in the time domain, a first time domain resource is configured after the first search space, and another first time domain resource is configured after the subsequent three search spaces.

[0131] The terminal device sends the first feedback information in the first time domain resources. This can be done by sending the first feedback information in all first time domain resources or by sending it in some first time domain resources. This application embodiment does not specifically limit this. The following describes two implementation methods for sending the first feedback information provided by the embodiments of this application.

[0132] Implementation method 1: In the time domain, if the first time domain resource arrives, the terminal device can send the first feedback information.

[0133] In this implementation, the terminal device can send the first feedback information on all first time-domain resources in the time domain. Alternatively, the terminal device can send the first feedback information on the first time-domain resource closest to each search space. Here, the first time-domain resource can be the time-domain resource associated with the search space and / or the first time window as described above, or it can be a specific time-domain resource as described above, i.e., a time-domain resource not associated with the search space and / or the first time window.

[0134] For example, such as Figure 4a As shown, if a first time domain resource is configured after each search space in the time domain, when the terminal device is woken up by the first wake-up signal, the terminal device can send the first feedback information on the first time domain resource after each search space.

[0135] For example, such as Figure 4bAs shown, if a first time domain resource is configured after every two search spaces in the time domain, when the terminal device is woken up by the first wake-up signal, the terminal device can send the first feedback information on the first time domain resource after every two search spaces.

[0136] For example, such as Figure 4c As shown, if the first time-domain resource is a specific time-domain resource, since the first time-domain resource is not associated with the search space and / or the first time window, then in the time domain, there is a first time-domain resource configured after the first search space, and another first time-domain resource configured after the subsequent three search spaces; when the terminal device is woken up by the first wake-up signal, the terminal device sends the first feedback information while listening to the first time-domain resource after the first search space, and sends the first feedback information while listening to the other first time-domain resource after the fourth search space.

[0137] For example, such as Figure 4d As shown, when the terminal device is woken up by the first wake-up signal, the terminal device can send the first feedback information on the first time domain resource after each first time window.

[0138] Implementation Method 2: In the time domain, if the first time domain resource arrives and the terminal device detects the control information, the terminal device can send the first feedback information.

[0139] In this implementation, the terminal device may send the first feedback information on the first time domain resource only after detecting control information in the search space. Alternatively, the terminal device may send the first feedback information on the first time domain resource closest to the search space after detecting control information in that search space. In other words, if the terminal device does not detect control information in a search space, it may choose not to send the first feedback information on the first time domain resource closest to that search space.

[0140] The first time-domain resource here can be the time-domain resource associated with the search space and / or the first time window as described above, or it can be a specific time-domain resource as described above, that is, a time-domain resource not associated with the search space and / or the first time window.

[0141] Furthermore, in some implementations, in the time domain, if the first time domain resource arrives and the terminal device has detected L control messages, then the terminal device may send the first feedback message. Alternatively, in the time domain, if the first time domain resource arrives and the terminal device has not detected L control messages, then the terminal device may not send the first feedback message. In other words, the terminal device may send the first feedback message only after detecting L control messages.

[0142] L is a positive integer greater than or equal to 1. For example, if L is 1, the terminal device can send a first feedback message when it hears each control message.

[0143] For example, such as Figure 5 As shown, when the terminal device is woken up by the first wake-up signal, if the terminal device detects control information in the first search space, it will send the first feedback information in the first time domain resource after the first search space; if the terminal device does not detect control information in the second and third search spaces, it will not send the first feedback information in the first time domain resource after the third search space; if the terminal device detects control information in the fourth search space, it will send the first feedback information in the first time domain resource after the fourth search space.

[0144] This application does not specifically limit the configuration method of the value of L in the embodiments. For example, the value of L can be predefined by the protocol. Or, the value of L can be configured by the network device, such as through RRC signaling.

[0145] It should be understood that the first time domain resource can be "a time domain resource determined according to the relevant information of the first time domain resource pre-specified by the instruction / configuration / protocol". The statement mentioned above, "in the time domain, if the first time domain resource arrives, the terminal device can send the first feedback information", can be understood as "the terminal device sends the first feedback information on the time domain resource determined according to the relevant information of the first time domain resource pre-specified by the instruction / configuration / protocol".

[0146] The statement mentioned above, "In the time domain, if the first time domain resource arrives and the terminal device detects the control information, then the terminal device can send the first feedback information," can be understood as "If the terminal device detects the control information before the first time domain resource, then the terminal device sends the first feedback information at the time domain resource determined according to the relevant information of the first time domain resource pre-specified by the instruction / configuration / protocol."

[0147] This application does not specifically limit the type of the first time-domain resource in its embodiments. In some implementations, the first time-domain resource can be a static time-domain resource, a semi-static time-domain resource, or a dynamic time-domain resource.

[0148] For example, the first time domain resource can be a time domain resource determined based on configuration authorization, such as a time domain resource determined based on configuration authorization Type1 and / or Type2.

[0149] This application does not specifically limit the configuration method of the first time-domain resource. In some implementations, the relevant information of the first time-domain resource can be predefined by the protocol. Alternatively, the relevant information of the first time-domain resource can be determined based on second indication information sent by the network device. This second indication information is used to indicate the relevant information of the first time-domain resource.

[0150] Furthermore, in some implementations, the second indication information can be carried in the first wake-up signal (such as LP-WUS) or control information. That is, the relevant information of the first time domain resource can be indicated or configured in the first wake-up signal or control information.

[0151] Alternatively, in some implementations, the second indication information can be determined based on the second configuration information sent by the network device. That is, the relevant information of the first time domain resource can be configured by the network device through configuration information, such as through RRC signaling. Three specific configuration methods for the relevant information of the first time domain resource are given below.

[0152] Configuration Method 1: Configure relevant information of the first time domain resources based on RRC signaling.

[0153] In this configuration method, the network device can configure a semi-static first time domain resource for the terminal device, such as a time domain resource determined according to the configuration authorization (e.g., Type 1 and / or Type 2); the network device can indicate in the relevant configuration of the time domain resource determined by the configuration authorization that the time domain resource is used to carry the first feedback information.

[0154] Alternatively, the terminal device can determine the relevant information of the first time-domain resource based on the configuration information in the RRC signaling of the resource dedicated to configuring the first feedback information.

[0155] In this configuration, the number of first time-domain resources can be associated with the number of search spaces and / or first time windows. In some implementations, one first time-domain resource can be associated with M search spaces. Alternatively, in other implementations, one first time-domain resource can be associated with N first time windows (see the description above for details).

[0156] The terminal device sends the first feedback information in the first time domain resource. This can be done by sending the first feedback information in all first time domain resources or by sending it in some first time domain resources. This application embodiment does not specifically limit this. The following describes two implementation methods for sending the first feedback information provided by this application embodiment. In some implementation methods, in the time domain, if the first time domain resource arrives, the terminal device can send the first feedback information. Alternatively, in other implementation methods, in the time domain, if the first time domain resource arrives and the terminal device detects control information, the terminal device can send the first feedback information (details can be found in the above description).

[0157] Configuration Method 2: Configure or indicate relevant information of the first time domain resource based on the first wake-up signal (such as LP-WUS).

[0158] In this configuration, the first wake-up signal can indicate relevant information about the first time-domain resource. For example, the relevant information about the first time-domain resource can include one or more of the following: the start time-domain position of the first time-domain resource, the end time-domain position of the first time-domain resource, the first time-domain offset, the duration of the first time-domain resource, and the period of the first time-domain resource.

[0159] Taking the first wake-up signal indicating the first time domain offset as an example, in some implementations, the first wake-up signal can indicate the first time domain offset of the starting time domain position or ending time domain position of the first time domain resource from each search space.

[0160] For example, the time slot offset of the starting time slot of the first time-domain resource from the time slot of the search space / LP-WUS can be used as an indicator of the time slot of the first time-domain resource, and the starting symbol position in the time slot of the first time-domain resource can be indicated; wherein, the time slot of the search space / LP-WUS can be the time slot of the starting time slot of the search space / LP-WUS time-domain resource or the time slot of the ending time slot of the search space / LP-WUS time-domain resource.

[0161] Alternatively, the offset of the starting time-domain position of the first time-domain resource from the symbol of the time-domain resource in the search space / LP-WUS can be used as an indicator of the LP-WUS, such as the offset of the symbol of the ending time-domain resource in the search space / LP-WUS.

[0162] In other implementations, the first wake-up signal can be used to indicate the first time-domain offset of the start or end time-domain position of the first time-domain resource from each first time window.

[0163] For example, the LP-WUS indicator can indicate the time slot offset of the starting time slot of the first time slot resource from the time slot of the first time window resource, and indicate the starting symbol position in the time slot of the first time slot resource; wherein, the time slot of the first time window resource can be the time slot of the starting time slot or the time slot of the ending time slot of the first time window.

[0164] Alternatively, the symbol offset of the starting time domain position of the first time domain resource from the time domain resource of the first time window can be based on the LP-WUS indicator, such as the offset of the symbol of the ending time domain resource of the first time window.

[0165] In some other implementations, the network device can pre-configure multiple candidate configuration information for the first time domain resource for the terminal device, and the first wake-up signal can indicate the target configuration information from the multiple candidate configuration information.

[0166] For example, network devices can configure K2 parameters and / or start and length indicator values ​​(SLIVs) for terminal devices via RRC signaling; terminal devices can determine K2 parameters and SLIVs based on the time domain resource allocation (TDRA) indicated by the received LP-WUS.

[0167] For example, network devices can pre-configure a resource table for terminal devices via RRC signaling. This resource table can contain multiple configuration information for the first time domain resource. The terminal device can then use the received LP-WUS instruction to select the target configuration information in the resource table.

[0168] For example, the resource table mentioned above may include multiple configuration information, such as multiple {slot offset, start symbol position, duration symbol length}, and LP-WUS indicates that one of the configuration information is the configuration information of the first time domain resource.

[0169] For example, the indication information in LP-WUS can indicate the sequential number of configuration information in the resource table. For instance, an indication value of "0" in LP-WUS can represent the first configuration information in the resource table.

[0170] Configuration method 3: Based on the monitored control information (hereinafter referred to as the first control information) indication.

[0171] In this configuration method, in some implementations, the first control information can directly indicate relevant information of the first time-domain resource. For example, the first control information can indicate one or more of the following: the offset of the starting time slot of the first time-domain resource from the time slot where the first control information is located, the position of the starting symbol in the starting time slot, the duration of the first time-domain resource, the offset of the ending time slot of the first time-domain resource from the time slot where the first control information is located / the starting time slot of the time-domain resource, and the position of the ending symbol in the ending time slot.

[0172] In other implementations, the network device can pre-configure multiple candidate configuration information for the first time domain resource for the terminal device, and the first control information can indicate the target configuration information from the multiple candidate configuration information.

[0173] For example, network devices can configure K2 parameters and / or start and length indicator values ​​(SLIVs) for terminal devices via RRC signaling; terminal devices can determine K2 parameters and SLIVs based on the time domain resource allocation (TDRA) indicated by the received DCI.

[0174] For example, network devices can pre-configure a resource table for terminal devices via RRC signaling. This resource table can contain multiple configuration information of the first time domain resources. The terminal device can then use the received DCI to indicate the target configuration information in the resource table.

[0175] For example, the resource table above may include multiple configuration information, such as multiple {slot offset, start symbol position, duration symbol length}, and DCI indicates that one of the configuration information is the configuration information of the first time domain resource.

[0176] For example, the indication information in the DCI can indicate the sequential number of the configuration information in the resource table. For instance, an indication value of "0" in the DCI can represent the first configuration information in the resource table.

[0177] In some implementations, the first control information can adopt a specific control information format, and / or, the first control information can adopt a specific scrambling method. In this way, the terminal device can distinguish the first control information from other control information. For example, the first control information can be scrambled using a specific radio network temporary identifier (RNTI), which is different from a traditional RNTI, such as a feedback-RNTI.

[0178] First frequency domain resources In some implementations, the relevant information of the first frequency domain resource may include one or more of the following: the starting frequency domain position of the first frequency domain resource, whether the first frequency domain resource is frequency hopping, the index information of the first frequency domain unit after the first frequency domain resource is frequency hopping, the format of the physical uplink control channel for transmitting the first feedback information (if the first frequency domain resource is carried on the physical uplink control channel), and whether the first frequency domain resource is continuous in the frequency domain.

[0179] Alternatively, in some implementations, the relevant information of the first frequency domain resource may include one or more of the following: the starting frequency domain position or the starting frequency domain position offset, the bandwidth size, the guard bandwidth size, the center frequency position or the center frequency offset, and the ending frequency domain position or the ending frequency domain position offset.

[0180] For example, the starting frequency domain location of the first frequency domain resource may include one or more of the following: the starting physical resource block (Starting PRB) of the first frequency domain resource, the absolute number of the starting PRB, and the offset relative to the starting location of the BWP or the cell center frequency point.

[0181] In some implementations, the first frequency domain resources are also used to transmit first signaling and / or the first channel. That is, the first frequency domain resources used to transmit the first signaling and / or the first channel can be reused to transmit the first feedback information.

[0182] In some implementations, the first signaling and / or the first channel may satisfy one or more of the following: the transmission timing of the first signaling and / or the first channel is earlier than the transmission timing of the first feedback information; the first signaling is associated with initial synchronization or random access; the first channel includes an uplink channel and / or a downlink channel.

[0183] For example, the first signaling could be message 1, message 2, message 3, or a synchronization signal block. Similarly, the first channel could be a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), a physical downlink control channel (PDCCH), or a physical downlink shared channel (PDSCH).

[0184] This application does not specifically limit the type of the first frequency domain resource in its embodiments. In some implementations, the first frequency domain resource can be a static frequency domain resource, a semi-static frequency domain resource, or a dynamic frequency domain resource.

[0185] For example, the first frequency domain resource can be a frequency domain resource determined based on configuration authorization, such as a frequency domain resource determined based on configuration authorization Type 1 and / or Type 2.

[0186] This application does not specifically limit the configuration method of the first frequency domain resources. In some implementations, the relevant information of the first frequency domain resources can be predefined by the protocol. Alternatively, the relevant information of the first frequency domain resources can be determined based on the first information sent by the network device.

[0187] Furthermore, in some implementations, the first information can be carried in the first wake-up signal (such as LP-WUS) or control information. That is, the relevant information of the first frequency domain resource can be indicated or configured in the first wake-up signal or control information.

[0188] Alternatively, in some implementations, the first information can be determined based on the third configuration information sent by the network device. That is, the relevant information of the first frequency domain resource can be configured by the network device through configuration information, such as through RRC signaling. Three specific configuration methods for the relevant information of the first frequency domain resource are given below.

[0189] Configuration Method 1: Configure relevant information of the first frequency domain resources based on the protocol predefined configuration.

[0190] In this configuration, the protocol pre-defines that the first frequency domain resources of the first signaling and / or the first channel can be reused to transmit the first feedback information.

[0191] For example, the first frequency domain resource can be the same as the frequency domain resource of the transmitted message 1, message 2, message 3, or synchronization signal block. Alternatively, the first frequency domain resource can be the same as the frequency domain resource of the last transmitted PUSCH or PUCCH. Another example is that the first frequency domain resource can be the same as the frequency domain resource of the last transmitted PDCCH or PDSCH. Yet another example is that the first resource can be the same as the resource of the transmitted synchronization signal block.

[0192] Configuration Method 2: Configure relevant information of the first frequency domain resources based on RRC signaling.

[0193] In this configuration method, the network device can configure a semi-static first frequency domain resource for the terminal device, such as a frequency domain resource determined according to the configuration authorization (e.g., Type 1 and / or Type 2); the network device can indicate in the relevant configuration of the frequency domain resource determined by the configuration authorization that the frequency domain resource is used to carry the first feedback information.

[0194] Alternatively, the terminal device can determine the relevant information of the first frequency domain resource based on the configuration information in the RRC signaling dedicated to configuring the first feedback information.

[0195] In some implementations, the configuration information in the RRC signaling may include one or more of the following: the starting frequency domain position of the first frequency domain resource, whether the first frequency domain resource is frequency hopping, the index information of the first frequency domain unit after the first frequency domain resource is frequency hopping, the format of the physical uplink control channel for transmitting the first feedback information (if the first frequency domain resource is carried on the physical uplink control channel), and whether the first frequency domain resource is continuous in the frequency domain.

[0196] Configuration method 3: Based on the monitored control information (hereinafter referred to as the second control information) / LP-WUS indication.

[0197] In this configuration, in some implementations, the second control information / LP-WUS can directly indicate relevant information about the first frequency domain resource. For example, the second control information / LP-WUS can indicate one or more of the following: the starting frequency domain position of the first frequency domain resource, whether the first frequency domain resource is frequency-hopping, the index information of the first frequency domain cell after frequency hopping, the format of the physical uplink control channel for transmitting the first feedback information (if the first frequency domain resource is carried on the physical uplink control channel), and whether the first frequency domain resource is continuous in the frequency domain.

[0198] In other implementations, the network device can pre-configure multiple candidate configuration information for the first frequency domain resources for the terminal device, and the second control information / LP-WUS can indicate the target configuration information from the multiple candidate configuration information.

[0199] For example, network devices can be pre-configured (e.g. via RRC signaling) with one or more of the following information: resource allocation type, indicating whether the resource allocation is contiguous or non-contiguous; resource block size.

[0200] Furthermore, the terminal device can determine relevant information about the first frequency domain resources based on the instructions of the second control information / LP-WUS, for example, it can determine one or more of the following information: For discontinuous resource allocation types, determine the location of the resource block occupied by the first frequency domain resource; for continuous resource allocation types, determine the starting resource block of the first frequency domain resource and / or the size of the continuously allocated resource blocks.

[0201] For example, for discontinuous resource allocation types, the location of the resource block occupied by the first frequency domain resource can be determined based on the bitmap information indicated in the DCI.

[0202] For example, for continuous resource allocation types, the starting resource block and the size of the continuously allocated resource blocks in the first frequency domain can be determined based on the resource indication value (RIV) in the DCI.

[0203] In some implementations, the second control information can adopt a specific control information format, and / or, the second control information can adopt a specific scrambling method. In this way, the terminal device can distinguish the second control information from other control information. For example, the second control information can be scrambled using a specific RNTI, which is different from a traditional RNTI, such as feedback-RNTI.

[0204] The preceding text introduced the first time-domain resources and the first frequency-domain resources for transmitting the first feedback information. The following text describes the method by which the terminal device is activated or deactivated to send the first feedback information according to embodiments of this application.

[0205] In some implementations, in response to receiving a third instruction from a network device, the terminal device may send a first feedback message; and / or, the terminal device may send the first feedback message in a second time window.

[0206] In other words, the terminal device can be activated and send the first feedback information after receiving the third instruction information. Alternatively, the terminal device can be activated and send the first feedback information within a second time window (or the duration of the feedback activity).

[0207] This application does not specifically limit the method of carrying the third indication information. In some implementations, the third indication information may be carried in the first wake-up signal (such as LP-WUS). Alternatively, the third indication information may be carried in the MAC CE or DCI.

[0208] This application does not specifically limit the configuration method of the second time window. In some implementations, the second time window may be predefined by the protocol.

[0209] Alternatively, in some implementations, the network device can send relevant information to the terminal device to indicate or configure a second time window.

[0210] For example, network devices can indicate a second time window by sending a third instruction message.

[0211] For example, the terminal device can send the first feedback information after receiving LP-WUS, MAC CE, or DCI.

[0212] For example, a second time window can be specified in LP-WUS, MAC CE, or DCI, and the terminal device can send the first feedback information in the second time window.

[0213] For example, after receiving an activation instruction from the MAC CE or DCI, the terminal device can determine whether to send the first feedback information based on the information subsequently received in the LP-WUS. The LP-WUS contains indication information telling the terminal device whether to send the first feedback information.

[0214] In some implementations, in response to receiving a fourth instruction message from the network device, the terminal device may stop sending the first feedback message; or, the terminal device may stop sending the first feedback message at a second time-domain reference point.

[0215] In other words, the terminal device can be deactivated upon receiving the fourth instruction information, thereby ceasing the transmission of the first feedback information. Alternatively, the terminal device can be deactivated at the second time-domain reference point, thereby ceasing the transmission of the first feedback information.

[0216] In some implementations, the second time-domain reference point may be associated with the end-time domain position of the first time window for listening to control information, and / or the second time-domain reference point may be associated with the end-time domain position of the second time window.

[0217] For example, the second time-domain reference point could be a time-domain position following the end of the first time window. That is, the transmission of the first feedback information can be stopped at a time-domain position following the first time window for monitoring control information. For instance, the first feedback information can be transmitted once after the first time window ends.

[0218] For example, the second time-domain reference point could be the time-domain position at the end of the second time window. In other words, the transmission of the first feedback information can be stopped at the end of the second time window.

[0219] This application does not specifically limit the method of carrying the fourth indication information. In some implementations, the fourth indication information may be carried on a MAC CE or a DCI.

[0220] For example, the terminal device can stop sending the first feedback information after receiving MAC CE or DCI.

[0221] This application does not specifically limit the method of carrying the first feedback information in its embodiments. In some implementations, the first feedback information can be carried on the physical uplink control channel or the physical uplink shared channel.

[0222] For example, if the first feedback information is carried on the physical uplink control channel, a specific uplink control information format can be used to carry the first feedback information, or a specific scrambling method can be used to scramble the uplink control information, such as using a specific RNTI that is different from the traditional RNTI.

[0223] For example, if the first feedback information is carried on the physical uplink shared channel, then MAC CE or RRC signaling can be used to carry the first feedback information.

[0224] This application does not specifically limit the information content included in the first feedback information. In some implementations, the first feedback information may include one or more of the following: fifth indication information, used to indicate whether the terminal device has detected control information; sixth indication information, used to indicate the number of times the terminal device has detected control information; and seventh indication information, used to indicate the number of times the terminal device has sent the first feedback information.

[0225] For example, the fifth indication information can be represented by one or more bits. For instance, the first feedback information may contain 1 bit, such as a bit value of "0" indicating that the terminal device has not received control information, and a bit value of "1" indicating that the terminal device has received control information.

[0226] For example, the sixth indication information can be represented by a bitmap or a counter. For instance, the first feedback information can contain a bitmap of M bits. Taking M as 6 as an example, the value of the bitmap "110000" represents that the terminal device listened to two control messages before sending the first feedback information.

[0227] Alternatively, the first feedback information can include a counter with N1 bits. Taking N1 as 4 as an example, the value of the counter "0000" represents that the terminal device has listened to the control information 0 times, the value of the counter "0001" represents that the terminal device has listened to the control information 1 time, and so on.

[0228] For example, the seventh indication information can be represented by a bitmap or a counter. For instance, the first feedback information can contain a bitmap of K bits. Taking K as 6 as an example, the value of the bitmap "110000" represents that the terminal device sent the first feedback information twice.

[0229] Alternatively, the first feedback information can include a counter of N2 bits. Taking N1 as 4 as an example, the value of the counter "0001" represents that the terminal device sent the first feedback information once, and so on.

[0230] It should be understood that the counters and bitmaps mentioned above may be configured by the network device for the terminal device or may be predefined by the protocol. This application embodiment does not specifically limit them.
