Description

Communication method and communication apparatus

[0001] This application claims priority to the Chinese Patent Application No. 202411337664.7, filed on September 24, 2024, and entitled "Communication method and communication apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of wireless communication, and more particularly, to a communication method and a communication apparatus. BACKGROUND

[0003] A terminal device can receive a wake-up signal through a single low-power small circuit, such as a wake-up radio (WUR), and a main receiver can be in a sleep state. When the terminal device detects the wake-up signal through the WUR, the terminal device triggers the wake-up of the main receiver. In a connected state, the terminal device can be configured to perform channel measurement. In the scenario where the terminal device is configured to perform channel measurement, how the wake-up signal works is a problem worth considering. SUMMARY

[0004] The present application provides a communication method and a communication apparatus, which can realize the terminal device to monitor the wake-up signal, and measure and / or report the channel information, and can reduce the probability of the terminal device missing the wake-up signal.

[0005] In a first aspect, a communication method is provided. The method can be applied to the terminal side, that is, the method can be executed by a terminal device, or can be executed by a component (such as a chip or a chip system or a circuit or a communication module) of the terminal device, which is not limited in the present application. Hereinafter, the terminal device is mainly taken as an example for description.

[0006] The method can include: receiving first configuration information, the first configuration information indicating a first time domain resource, the first time domain resource being a time domain resource for monitoring a wake-up signal; receiving second configuration information, the second configuration information indicating to measure and / or report channel information in a second time domain resource, the second time domain resource being a time period indicated by a discontinuous reception duration timer (drx-onDurationTimer); monitoring the wake-up signal in a time domain resource in the first time domain resource that does not overlap with a third time domain resource, the third time domain resource being the second time domain resource, or the third time domain resource being a partial time domain resource of the second time domain resource.

[0007] Optionally, the method further comprises, or the "monitoring the wake-up signal in the time domain resource that does not overlap with the third time domain resource in the first time domain resource" can be replaced by: (determining) not monitoring the wake-up signal in the third time domain resource; or, (determining) stopping (or suspending) monitoring the wake-up signal in the third time domain resource; or, (determining) deactivating monitoring the wake-up signal in the third time domain resource.

[0008] Based on the above technical solutions, after receiving the configuration information, the terminal device can determine the time domain resource (i.e., the first time domain resource) for monitoring the wake-up signal and the second time domain resource for measuring and / or reporting the channel information. Therefore, when the first time domain resource overlaps with the third time domain resource (i.e., the second time domain resource or part of the second time domain resource), the terminal device can only monitor the wake-up signal in the time domain resource that does not overlap, i.e., not monitor (or stop monitoring, suspend monitoring, deactivate monitoring, etc.) the wake-up signal in the overlapping time domain resource. In this way, the terminal device does not need to monitor the wake-up signal and measure and / or report the channel information at the same time, thereby reducing the requirements on the terminal device. In addition, based on this, the terminal device and the network device can timely learn the channel condition between them, and as much as possible avoid the situation that the channel condition between the terminal device and the network device becomes poor, so that even if the network device sends a wake-up signal, the terminal device may not be able to monitor the wake-up signal. Further, the probability of the terminal device missing the wake-up signal can be reduced.

[0009] In a second aspect, a communication method is provided. The method can be applied to the terminal side, i.e., the method can be executed by a terminal device, or can be executed by a component (such as a chip or a chip system or a circuit or a communication module) of the terminal device, and the present application does not limit this. Hereinafter, the terminal device will be mainly taken as an example for description.

[0010] The method can comprise: receiving second configuration information, the second configuration information indicating to measure and / or report channel information in a second time domain resource, the second time domain resource being a time period indicated by a discontinuous reception duration timer dRx-onDurationTimer; and determining not to monitor the wake-up signal in a third time domain resource, the third time domain resource being the second time domain resource, or the third time domain resource being part of the second time domain resource.

[0011] Based on the above technical solution, when the network device configures the terminal device to measure and / or report channel information in the second time domain resource, the terminal device can determine not to monitor (or stop monitoring, suspend monitoring, deactivate monitoring, etc.) the wake-up signal in the third time domain resource (i.e., the second time domain resource or part of the second time domain resource). In this way, the terminal device and the network device can timely learn the channel condition between them, and the probability of the terminal device not monitoring the signal (such as the wake-up signal) sent by the network device can be reduced.

[0012] In some implementations, in combination with the first aspect or the second aspect, the third time domain resource is part of the second time domain resource, and the part of the second time domain resource includes at least one of a time domain resource of a reference signal, a time domain resource of an uplink channel, wherein the reference signal is used to measure the channel information, and the uplink channel is used to report the channel information.

[0013] In some implementations, in combination with the first aspect or the second aspect, the third time domain resource further includes at least one of a fourth time domain resource located before the time domain resource of the uplink channel, an end position of the fourth time domain resource being a start position of the time domain resource of the uplink channel; a fifth time domain resource located after the time domain resource of the uplink channel, a start position of the fifth time domain resource being an end position of the time domain resource of the uplink channel; a sixth time domain resource located before the time domain resource of the reference signal, an end position of the sixth time domain resource being a start position of the time domain resource of the reference signal; and a seventh time domain resource located after the time domain resource of the reference signal, a start position of the seventh time domain resource being an end position of the time domain resource of the reference signal.

[0014] Based on the above technical solution, considering that the terminal device may need time to switch from monitoring the wake-up signal to measuring and / or reporting the channel information, the third time domain resource can further include at least one of a time domain resource before the time domain resource of the reference signal used to measure the channel information, a time domain resource after the time domain resource of the reference signal used to measure the channel information, a time domain resource before the time domain resource of the uplink channel used to report the channel information, and a time domain resource after the time domain resource of the uplink channel used to report the channel information. In this way, the switching time between different operations of the terminal device can be taken into account.

[0015] In some implementations, in combination with the first aspect or the second aspect, the method further includes receiving third configuration information, the third configuration information indicating the time domain resource of the reference signal and / or the time domain resource of the uplink channel, and the time domain resource of the reference signal and / or the time domain resource of the uplink channel not monitoring the wake-up signal.

[0016] Based on the above technical solution, the network device indicates the time domain resource of the reference signal and / or the time domain resource of the uplink channel to the terminal device, and the terminal device can determine the time domain position of the wake-up signal that is not monitored according to the position of the configured time domain resource of the reference signal and / or the time domain resource of the uplink channel. For example, it can be predefined that the wake-up signal is not monitored on the time domain resource of the reference signal and / or the time domain resource of the uplink channel.

[0017] In some implementations, in combination with the first aspect or the second aspect, the method further includes: receiving fourth configuration information, the fourth configuration information indicating the third time domain resource.

[0018] Based on the above technical solution, the network device can indicate the position of the time domain resource of the wake-up signal that is not monitored to the terminal device, which can facilitate the terminal device to determine which positions do not monitor the wake-up signal.

[0019] In some implementations, in combination with the first aspect or the second aspect, the fourth configuration information includes at least one of the following: a starting position of the third time domain resource, a length of the third time domain resource, an ending position of the third time domain resource.

[0020] In some implementations, in combination with the first aspect or the second aspect, the method further includes: measuring and / or reporting the channel information in the third time domain resource.

[0021] In some implementations, in combination with the first aspect or the second aspect, the terminal device includes a first circuit and a second circuit, and the monitoring the wake-up signal in the first time domain resource includes: the terminal device monitoring the wake-up signal in the first time domain resource through the first circuit; and the measuring and / or reporting the channel information includes: the terminal device measuring and / or reporting the channel information through the second circuit.

[0022] In some implementations, in combination with the first aspect or the second aspect, the channel information includes at least one of the following: periodic channel state information (CSI); and periodic layer 1 reference signal received power (L1-RSRP).

[0023] Based on the above technical solution, the terminal device can measure and report the periodic CSI and the periodic L1-RSRP at a specific position, so that the terminal device and the network device can timely know the channel condition therebetween, so that the network device can make appropriate configuration and scheduling adjustment to the terminal device according to the channel condition.

[0024] In some implementations, in combination with the first aspect or the second aspect, the method further includes: not monitoring a physical downlink control channel (PDCCH) in the third time domain resource; or monitoring a PDCCH in the third time domain resource.

[0025] Based on the above technical solution, if the terminal device does not monitor the PDCCH in the third time domain resource, the terminal device can save power consumption; if the terminal device monitors the PDCCH in the third time domain resource, and the service of the terminal device happens to arrive at this time, the network device can send scheduling information to the terminal device at the third time domain resource, thereby shortening the data transmission delay.

[0026] In combination with the first aspect or the second aspect, in some implementations, the second time domain resource is a time period indicated by a discontinuous reception duration timer drx-onDurationTimer, including: the second time domain resource is a time period indicated by the drx-onDurationTimer outside an active time Active Time; or the second time domain resource is a time period indicated by the drx-onDurationTimer, which is not running.

[0027] Based on the above technical solution, even if the terminal device is outside the Active Time, or the drx-onDurationTimer corresponding to the terminal device is not running, the terminal device can still measure and report periodic CSI and periodic L1-RSRP at a specific location, so that the terminal device and the network device can timely learn the channel condition between them, so that the network device can make appropriate configuration and scheduling adjustment for the terminal device according to the channel condition.

[0032] In some implementations in combination with the third aspect or the fourth aspect, the third time domain resource is a partial time domain resource of the second time domain resource, and the partial time domain resource includes at least one of: a time domain resource of a reference signal, the reference signal being used to measure the channel information; and a time domain resource of an uplink channel, the uplink channel being used to report the channel information.

[0033] In some implementations in combination with the third aspect or the fourth aspect, the third time domain resource further includes at least one of: a fourth time domain resource located before the time domain resource of the uplink channel, an end position of the fourth time domain resource being a start position of the time domain resource of the uplink channel; a fifth time domain resource located after the time domain resource of the uplink channel, a start position of the fifth time domain resource being an end position of the time domain resource of the uplink channel; a sixth time domain resource located before the time domain resource of the reference signal, an end position of the sixth time domain resource being a start position of the time domain resource of the reference signal; and a seventh time domain resource located after the time domain resource of the reference signal, a start position of the seventh time domain resource being an end position of the time domain resource of the reference signal.

[0039] The beneficial effects and possible designs related to the third aspect and the fourth aspect can be referred to the related descriptions in the first aspect and the second aspect, and will not be repeated here.

[0040] A fifth aspect provides a communication method. The method can be applied to a terminal side, i.e., the method can be executed by a terminal device, or can be executed by a component (e.g., a chip or a chip system or a circuit or a communication module) of the terminal device, which is not limited in the present application. Hereinafter, the terminal device will be mainly taken as an example for description.

[0041] The method can include: receiving first configuration information, the first configuration information indicating N time domain units, the N time domain units being time domain units for monitoring a wake-up signal, N being an integer greater than 1; if the wake-up signal is monitored on a time domain unit in the N time domain units that overlaps with a time window, performing a first operation; if the wake-up signal is monitored on a time domain unit in the N time domain units that does not overlap with the time window, performing a second operation; wherein the time window is associated with a duration onDuration.

[0042] Based on the above technical solutions, the network side can configure N time domain units for the terminal device to monitor the wake-up signal, and part of the N time domain units overlap with the time window. The terminal device performs the first operation when the wake-up signal is monitored on the time domain unit that overlaps with the time window, and the terminal device performs the second operation when the wake-up signal is monitored on the time domain unit that does not overlap with the time window. In this way, the terminal device can be configured with multiple schemes of the wake-up signal, i.e., the wake-up signals monitored on different time domain units are used to trigger the terminal device to perform different operations.

[0043] In some implementations of the fifth aspect, in response to monitoring the wake-up signal on the time domain unit that overlaps with the time window among the N time domain units, the first operation is triggered, including: in response to monitoring the wake-up signal on the time domain unit that overlaps with the time window among the N time domain units, a first timer is started.

[0044] Based on the above technical solution, the terminal device starts a timer in response to monitoring the wake-up signal on the time domain unit that overlaps with the time window, and starts another timer in response to monitoring the wake-up signal on the time domain unit that does not overlap with the time window. In this way, the terminal device can be configured with multiple schemes of the wake-up signal, that is, the wake-up signals monitored on different time domain units are used to trigger the terminal device to start different timers.

[0045] In some implementations of the fifth aspect, the first timer is a discontinuous reception duration timer drx-onDurationTimer.

[0046] In some implementations of the fifth aspect, the first configuration information includes at least one of the following: a periodicity value of the N time domain units, an offset of the N time domain units.

[0047] Based on the above technical solution, the N time domain units configured by the network side can be periodic.

[0048] In some implementations of the fifth aspect, the method further includes: receiving second configuration information, the second configuration information including at least one of the following: a starting position of the time window, a time length of the time window, an ending position of the time window, an offset between the time window and the onDuration.

[0049] Based on the above technical solution, the network side can indicate the time window to the terminal device. In this way, the terminal device can determine the first time domain unit and the second time domain unit based on the position of the time window, and then perform corresponding operations based on the wake-up signals monitored on different time domain units.

[0050] In some implementations of the fifth aspect, the method further includes: determining, based on the second configuration information, that the first operation is performed in response to monitoring the wake-up signal on the time domain unit that overlaps with the time window among the N time domain units.

[0051] Based on the above technical solution, when the terminal device monitors the wake-up signal on the time domain unit overlapping with the time window, if the network side configures the time window, that is, the terminal device receives the second configuration information, the terminal device performs the first operation.

[0052] In combination with the fifth aspect, in some implementations of the fifth aspect, if the wake-up signal is monitored on the time domain unit overlapping with the time window in the N time domain units, the first operation is performed, including: if the wake-up signal is monitored on the time domain unit overlapping with the time window in the N time domain units, and the wake-up signal carries the first information, the first operation is performed.

[0053] Based on the above technical solution, when the terminal device monitors the wake-up signal on the time domain unit overlapping with the time window, the terminal device can determine whether to perform the first operation or the second operation according to the information carried in the wake-up signal. For example, if the terminal device monitors the wake-up signal on the time domain unit overlapping with the time window, and the wake-up signal carries the first information, the terminal device performs the first operation.

[0054] In combination with the fifth aspect, in some implementations of the fifth aspect, the method further includes: if the wake-up signal is monitored on the time domain unit overlapping with the time window in the N time domain units, and the wake-up signal carries the second information, the second operation is performed.

[0055] Based on the above technical solution, when the terminal device monitors the wake-up signal on the time domain unit overlapping with the time window, the terminal device can determine whether to perform the first operation or the second operation according to the information carried in the wake-up signal. For example, if the terminal device monitors the wake-up signal on the time domain unit overlapping with the time window, and the wake-up signal carries the second information, the terminal device performs the second operation.

[0056] In combination with the fifth aspect, in some implementations of the fifth aspect, if the wake-up signal is monitored on the time domain unit overlapping with the time window in the N time domain units, the first operation is performed, including: based on the priority information, if the wake-up signal is monitored on the time domain unit overlapping with the time window in the N time domain units, the first operation is performed.

[0057] Based on the above technical solution, when the terminal device monitors the wake-up signal on the time domain unit overlapping with the time window, the terminal device can determine whether to perform the first operation or the second operation according to the priority information (such as the priority information indicated by the network side, or the pre-defined priority information). For example, if the terminal device monitors the wake-up signal on the time domain unit overlapping with the time window, and the priority of the first operation is higher than the priority of the second operation, the terminal device performs the first operation.

[0058] In some implementations of the fifth aspect, the method further includes determining, based on the priority information, to perform a second operation if the wake-up signal is monitored on the time-domain unit that overlaps with the time window.

[0059] Based on the above technical solution, if the terminal device monitors the wake-up signal at the time-domain unit that overlaps with the time window, the terminal device can determine whether to perform the first operation or the second operation according to the priority information (such as the priority information indicated by the network side or the predefined priority information). For example, if the terminal device monitors the wake-up signal on the time-domain unit that overlaps with the time window and the priority of the second operation is higher than the priority of the first operation, the terminal device performs the second operation.

[0060] A sixth aspect provides a communication method. The method can be applied to the network side, that is, the method can be performed by a network device or a component (such as a chip or a chip system or a circuit or a communication module) of the network device, and the present application does not limit this.

[0062] In some implementations of the sixth aspect, the first operation is starting a first timer, and the second operation is starting a second timer.

[0063] In some implementations of the sixth aspect, the first timer is a discontinuous reception duration timer dRx-onDurationTimer.

[0064] In some implementations of the sixth aspect, the first configuration information includes at least one of a periodicity value of the N time-domain units and an offset of the N time-domain units.

[0065] In some implementations of the sixth aspect, the method further includes: sending second configuration information, the second configuration information including at least one of a starting position of the time window, a time length of the time window, an ending position of the time window, and an offset between the time window and the onDuration.

[0066] With reference to the sixth aspect, in some implementations of the sixth aspect, the second time domain unit further includes part or all of the N time domain units that overlap with the time window.

[0067] The benefits and possible designs with respect to the sixth aspect can be referred to the descriptions of the fifth aspect, which will not be repeated here.

[0068] The seventh aspect provides a communication method.

[0113] The technical solutions in the present application will be described below with reference to the accompanying drawings.

[0114] Before introducing the solutions of the present application, the following points are explained.

[0115] (1) In this application, "indication" can include direct indication, indirect indication, explicit indication, implicit indication, etc. When describing that certain indication information indicates A, it can be understood that the indication information carries A, carries an identifier of A, carries B having an association relationship with A, carries an identifier of B having an association relationship with A, etc. In other words, if the receiving side of certain indication information can determine A according to the indication information, it can be described that the indication information indicates A, and the specific determination is not limited. When it is understood that the indication information carries A, "indication" can be replaced by "includes", at this time, similar to the expression "sending / receiving indication information, the indication information indicates A", it can be replaced by "sending / receiving A".

[0116] In this application, the information indicated by the indication information is referred to as to-be-indicated information. In the specific implementation process, there are many ways to indicate the to-be-indicated information, for example, but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or an index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, wherein the other information has an association relationship with the to-be-indicated information. The to-be-indicated information can also be only indicated a part, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can also be realized by means of the arrangement order of each information agreed in advance (for example, the protocol stipulates), thereby reducing the indication overhead to a certain extent. In addition, the to-be-indicated information can be sent as a whole, or can be sent separately into multiple sub-information, and the sending period and / or sending time of these sub-information can be the same or different.

[0117] (2) In this application, the expression " / " is used to represent that the objects before and after the association are in an "or" relationship; for example, A / B can represent A or B. The expression "and / or" is used to represent that the objects before and after the association can be in an "and" association relationship or an "or" association relationship; for example, A and / or B can represent the following cases: A exists alone, B exists alone, A and B exist together, wherein A and B can be single or multiple. "At least one of the following" or similar expressions are used to represent any combination of the listed items; for example, at least one of A, B and (or) C can represent the following cases: A exists alone, B exists alone, C exists alone, A and B exist together, B and C exist together, A and C exist together, A, B and C exist together, wherein A, B and C can be single or multiple.

[0118] (3) In this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include direct transmission via the air interface or indirect transmission by other units or modules via the air interface. "Receive information from YY" can be understood as the source of the information being YY, which may include direct reception from YY via the air interface or indirect reception from YY via other units or modules via the air interface. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface. In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via a bus, wiring, or interface.

[0119] (4) In the various embodiments of this application, unless otherwise specified or in case of logical conflict, the terms and / or descriptions of different embodiments are consistent and can be referenced by each other. The technical features of different embodiments can be combined to form new embodiments according to their inherent logical relationship.

They are not used to describe the order or sequence of features. It should be understood that such described objects can be interchanged where appropriate in order to describe solutions other than those in the embodiments of this application.

[0121] (6) In this application, "predefined" can mean a standard protocol predefined, or it can mean a pre-agreed or pre-negotiated agreement between devices. Here, "protocol" can refer to a standard protocol in the field of communications, for example, it may include fourth-generation (4G) protocols. th Generation 4G network, fifth generation (5G) network th This application does not limit the scope to network protocols such as 5G (generation, 5G), New Radio (NR), 5.5G, and related protocols used in future communication networks.

No inference should be drawn that any other implementation is "preferred" or "constitutes all other implementations." The word "example" is used herein to mean one of a number of possible implementations, and not necessarily the preferred or advantageous implementation. In the embodiments of this application, "of", "corresponding" and "corresponding" are sometimes mixed. It should be pointed out that when there is no emphasis on their differences, the meanings expressed are consistent.

[0138] In combination with FIG. 1, a communication system suitable for the embodiment of the present application is briefly introduced as follows.

[0139] Referring to FIG. 1, as an example, FIG. 1 is a schematic diagram of a wireless communication system suitable for the embodiment of the present application. As shown in FIG. 1, the wireless communication system includes a radio access network 100. The radio access network 100 can be a next-generation (for example, future or higher version) radio access network, or a traditional (for example, 5G, 4G, 3G or 2G) radio access network. One or more terminal devices (120a-120j, collectively referred to as 120) can be connected to each other or connected to one or more network devices (110a, 110b, collectively referred to as 110) in the radio access network 100.

[0140] In the communication between the network device and the terminal device, the network device can manage one or more cells, and each cell can include at least one terminal device. The cell can be understood as an area within the coverage range of the wireless signal of the network device.

[0141] FIG. 1 is only a schematic diagram, and the wireless communication system can also include other devices, such as core network devices, wireless relay devices and / or wireless backhaul devices, etc., which are not shown in FIG. 1.

[0142] In order to facilitate the understanding of the embodiments of the present application, the terms involved in the present application are briefly explained.

[0143] 1、wake up circuit: or called wake up receiver / radio (WUR) or low-power wake up receiver (LP-WUR) or wake up module, which can be understood as a separate low-power small circuit, such as a circuit used by a terminal device in an idle state. The low-power small circuit can be implemented using a simple structure of a separate small circuit or chip, and has low power consumption. It can be understood that the wake up circuit is only named for distinction, and its specific name does not limit the protection scope of the present application, for example, without loss of generality, the wake up circuit can also be described as a first circuit (or a first module). Hereinafter, it is uniformly described as a wake up circuit.

[0144] The signal received by the terminal device through the wake up circuit can be referred to as transmission on a wake up link, wherein the wake up link represents a connection relationship between the terminal device and the network device, and is a logical concept rather than a physical entity. It can be understood that the wake up link is only named for distinction, and its specific name does not limit the protection scope of the present application, for example, without loss of generality, the wake up link can also be described as a first link. Hereinafter, it is uniformly described as a wake up link.

[0145] The signal received by the terminal device using the wake up circuit can be referred to as a wake up signal (WUS) or a low power wake up signal (LP-WUS). It can be understood that the wake up signal is only named for distinction, and its specific name does not limit the protection scope of the present application, for example, without loss of generality, the wake up signal can also be referred to as a signal. Hereinafter, it is uniformly described as a wake up signal.

[0146] 2、main circuit: or called main receiver (MR) or main module, which can be understood as a circuit used by a terminal device when normally transmitting data, or a circuit used by a terminal device when transmitting data in a connected state. For example, a circuit or module used by a terminal device when performing a paging receiving process in an idle state or an inactive state, and for example, a circuit or module used by a terminal device when performing data transmission and reception in a connected state, can be a main circuit or a main module. When the terminal device transmits data through the main circuit, the power consumption is large. It can be understood that the main circuit is only named for distinction, and its specific name does not limit the protection scope of the present application, for example, without loss of generality, the main circuit can also be described as a second circuit (or a second module). Hereinafter, it is uniformly described as a main circuit.

[0147] The signal received by the terminal device through the main circuit can be referred to as being transmitted on a main link, where the main link represents a connection relationship between the terminal device and the network device, and is a logical concept rather than a physical entity. It can be understood that the main link is merely named for differentiation, and its specific naming does not limit the protection scope of the present application. For example, without loss of generality, the main link can also be described as a second link. Hereinafter, it is uniformly described as a main link.

[0148] Hereinafter, for differentiation, the signal transmitted by the terminal device using the main circuit is referred to as a data signal.

[0149] Referring to FIG. 2, FIG. 2 is a schematic diagram of the main circuit and the wake-up circuit, as an example.

[0150] As shown in FIG. 2, the terminal device can receive (or detect, or monitor) a wake-up signal through the wake-up circuit, and the terminal device can receive a data signal through the main circuit. It is assumed that the terminal device receives the wake-up signal through the wake-up circuit. If the terminal device does not detect the wake-up signal, the terminal device continues to receive the wake-up signal through the wake-up circuit, and the main circuit can be in a closed state (or a sleep state); if the terminal device detects the wake-up signal, the terminal device triggers the wake-up of the main circuit, that is, the terminal device causes / switches the main circuit to be in an open state (or referred to as a working state, or referred to as an active state). After the main circuit is opened, the terminal device can transmit the data signal through the main circuit.

[0151] As an example, when the terminal device is in an idle state or an inactive state, the wake-up signal can be used to carry paging-related information. When the terminal device is in a connected state, the wake-up signal can be used to carry scheduling-related information, for example, the wake-up signal is used to indicate whether the terminal device needs to open the main circuit to receive scheduling information (such as whether to monitor a physical downlink control channel (PDCCH)).

[0152] 3. On off key (OOK) modulation: using the transmission or non-transmission of a signal to modulate information, and the corresponding wake-up circuit can use an envelope detection method to receive the signal. The OOK modulation technology can realize demodulation with a receiver having very low complexity, so as to realize the low-power consumption goal of the wake-up circuit. In order to guarantee the power consumption benefit, the wake-up signal can adopt OOK modulation. It can be understood that the wake-up signal can also adopt other modulation modes, which are not limited.

[0153] When the signal adopts OOK modulation, each bit (that is, a coded bit) can correspond to a symbol. Equivalently, a symbol can also be referred to as a chip, or other names, which are not limited here.

[0154] For example, when the bit is "1", there is signal emission within the symbol length (i.e. the signal transmission power within the symbol length is not 0); when the bit is "0", there is no signal emission within the symbol length (i.e. the signal transmission power within the symbol length is 0). Alternatively, it can also be understood that in OOK modulation, if energy is transmitted, it represents "1", and if no energy is transmitted, it represents "0".

[0155] For another example, when the bit is "0", there is signal emission within the symbol length (i.e. the signal transmission power within the symbol length is not 0); when the bit is "1", there is no signal emission within the symbol length (i.e. the signal transmission power within the symbol length is 0). Alternatively, it can also be understood that in OOK modulation, if energy is transmitted, it represents "0", and if no energy is transmitted, it represents "1".

[0156] Hereinafter, for ease of description, an exemplary description is mainly given by taking an example of when the bit is "1", there is signal emission within the symbol length; and when the bit is "0", there is no signal emission within the symbol length.

[0157] In addition, for ease of description, if there is signal emission within a symbol, the symbol is recorded as an ON symbol; and if there is no signal emission within a symbol, the symbol is recorded as an OFF symbol. Taking an example of when the bit is "1", there is signal emission within the symbol length; and when the bit is "0", there is no signal emission within the symbol length, the ON symbol represents that the information bit is "1", and the OFF symbol represents that the information bit is "0". The ON symbol can also be referred to as an ON signal, and the OFF symbol can also be referred to as an OFF signal. For uniformity, hereinafter, the ON symbol and the OFF symbol are described.

[0158] The signal amplitude of the ON symbol is greater than or equal to the first threshold value, and the signal amplitude of the OFF symbol is less than or equal to the second threshold value; or the signal amplitude of the ON symbol is greater than the signal amplitude of the OFF symbol; or the signal amplitude of the ON symbol is greater than the signal amplitude of the OFF symbol in a preset time period; or the signal power of the ON symbol is greater than the signal power of the OFF symbol; or the signal power of the ON symbol is greater than the signal power of the OFF symbol in a preset time period; or the signal power of the ON symbol is greater than or equal to the first threshold value, and the signal power of the OFF symbol is less than or equal to the second threshold value; or the signal power of the ON symbol is greater than or equal to the first threshold value, and the signal power of the OFF symbol is less than or equal to the second threshold value in a preset time period; or the signal level value of the ON symbol is greater than the signal level value of the OFF symbol; or the signal level value of the ON symbol is greater than the signal level value of the OFF symbol in a preset time period; or the signal level value of the ON symbol is greater than or equal to the first threshold value, and the signal level value of the OFF symbol is less than or equal to the second threshold value; or the signal level value of the ON symbol is greater than or equal to the first threshold value, and the signal level value of the OFF symbol is less than or equal to the second threshold value in a preset time period; or the ON symbol indicates (or corresponds to, or represents) a first bit value, and the OFF symbol indicates (or corresponds to, or represents) a second bit value. The first bit value and the second bit value are different. In an example, the first bit value is "1", and the second bit value is "0".

[0159] In addition, the OOK symbol mentioned below refers to a symbol obtained by OOK modulation. The OOK symbol can be an ON symbol or an OFF symbol. For example, if the information bit is "1", the OOK symbol obtained by OOK modulation is an ON symbol, and if the information bit is "0", the OOK symbol obtained by OOK modulation is an OFF symbol. The OOK symbol can also be referred to as an OOK signal. For the sake of unity, the OOK symbol is described below.

[0160] Referring to FIG. 3, as an example, FIG. 3 is a waveform diagram when a signal is modulated by OOK.

[0161] As an example, it is assumed that when the bit is "1", a signal is emitted within the length of the OOK symbol, and when the bit is "0", no signal is emitted within the length of the OOK symbol, so the waveform shown in FIG. 3 can represent "0100" four bits, that is, the first is an OFF symbol, the second is an ON symbol, and the third and fourth are OFF symbols. As shown in FIG. 3, the communication system generally transmits using a certain frequency. The transmitted signal needs to be modulated on a carrier. At the receiving end, the receiving end detects the envelope (or energy) of the received signal to determine whether the OOK symbol corresponds to bit "0" or bit "1", thereby completing demodulation.

[0162] After the signal passes through the channel, distortion can occur due to the influence of the channel state, etc. Therefore, in order to determine whether the signal corresponds to bit "0" or bit "1", the receiving end can compare the received signal level value with a threshold. For example, if the received signal level value received by the receiving end is greater than the threshold, it indicates that the signal corresponds to bit "1"; if the received signal level value received by the receiving end is less than the threshold, it indicates that the signal corresponds to bit "0". However, it is difficult to set the threshold. For example, if the threshold is not selected properly, it can lead to demodulation errors. In order to solve this problem, one possible way is to use Manchester coding.

[0163] 4. Manchester coding: a kind of bi-phase coding, which can represent bit "0" or bit "1" through the high-low conversion of the level. For example, through Manchester coding, the original bit "0" can be encoded as bit "10", and the original bit "1" can be encoded as bit "01". For distinction, the bits after encoding of the original bits, such as bit "10" and "01", can be referred to as encoded bits. When transmitting the signal, the transmitting end can use two OOK symbols to transmit one bit of original information. If the original bit "0" is encoded as bit "10", and the original bit "1" is encoded as bit "01", then the original bit "0" corresponds to one ON symbol followed by one OFF symbol, and the original bit "1" corresponds to one OFF symbol followed by one ON symbol. When demodulating the Manchester coded signal, the receiving end can compare the relative size of the signal power (or signal amplitude) in the adjacent two OOK symbols. If the signal power (or signal amplitude) in the former OOK symbol is greater than the signal power (or signal amplitude) in the latter OOK symbol, it is considered that the received information bit is "0", and vice versa. In this way, the selection of an absolute threshold for decision can be avoided.

[0164] It can be understood that the above example of encoding the original bit "0" as bit "10" and the original bit "1" as bit "01" is illustrative and is not limited thereto. For example, the original bit "0" can be encoded as bit "01", and the original bit "1" can be encoded as bit "10".

[0165] As an example, the signal can be generated based on an orthogonal frequency division multiplexing (OFDM) transmitter, i.e., the OFDM transmitter can be used for modulation of the signal.

[0166] One possible way is to transmit one OOK symbol within the length of one OFDM symbol, or one OOK symbol occupies one OFDM symbol. For example, when transmitting an ON symbol within the length of one OOK symbol, the transmitter can send a specific signal, so that the profile of the signal within the length of the OOK symbol is as close to a square wave as possible; when transmitting an OFF symbol within the length of one OOK symbol, the transmitter can turn off the signal for the length of one OOK symbol.

[0167] Referring to FIG. 4, as an example, FIG. 4 is a schematic diagram of a waveform of a signal after Manchester encoding. As shown in FIG. 4, the original bits are “0 0 1 0 0 1 0 1 1 0”, and assuming that the original bit “0” is encoded as “10” and the original bit “1” is encoded as “01”, the encoded bits after Manchester encoding are “10 10 01 10 10 01 10 01 01 10”, and the waveform is as shown in FIG. 4. Each encoded bit corresponds to a length of time, which can be considered as the length of one OFDM symbol, that is, one OOK symbol is transmitted within the length of one OFDM symbol, or one OOK symbol occupies one OFDM symbol. When demodulating the signal, the receiver can compare the relative sizes of the signal powers (or signal amplitudes) in adjacent two OOK symbols, and determine the demodulated information bits based on the comparison result.

[0168] In the above manner, one OOK symbol is transmitted within the length of one OFDM symbol, which is simple, but the supported data rate is also relatively low. Because in the above manner, no matter how large the signal bandwidth is, one OOK symbol is transmitted within the length of one OFDM symbol. If the system uses a sub-carrier space (SCS) of 30 kHz and a slot length of 0.5 ms, one slot contains 14 OFDM symbols, in this case, assuming that no encoding is used, each OOK symbol carries 1 bit of information, and the maximum supported data rate is 1 / 0.5*14*1000 = 28 kbps.

[0169] To improve the data rate of the OOK symbol, one possible way is to shorten the length of the OOK symbol, that is, at least two OOK symbols are transmitted within the length of one OFDM symbol, or at least two OOK symbols occupy one OFDM symbol.

[0170] Referring to FIG. 5, as an example, FIG. 5 is another schematic diagram of a waveform after a signal is encoded by Manchester encoding. As shown in FIG. 5, the original bits are "0 0 0 1", assuming that the original bit "0" is encoded as "10" and the original bit "1" is encoded as "01", then the encoded bits after Manchester encoding are "10 10 10 10 01", and the waveform is as shown in FIG. 5. Among them, in one OFDM symbol length (2192 sampling points in FIG. 5), 8 OOK symbols are sent, which are ON symbol-OFF symbol-ON symbol-OFF symbol-ON symbol-OFF symbol-OFF symbol-ON symbol. When demodulating the signal, the receiving end can compare the relative size of the signal power (or signal amplitude) of the adjacent two OOK symbols, and determine the demodulated information bits based on the comparison result.

[0171] In order to generate the above waveform, one possible implementation is to first determine the target waveform x in the time domain, and then perform some operations such as discrete fourier transformation (DFT), inverse fast fourier transform (IFFT), and then obtain the sequence to be sent.

[0172] Referring to FIGS. 6 and 7, as an example, FIGS. 6 and 7 are schematic diagrams of OOK symbols in time domain and frequency domain. As shown in FIG. 6, assuming that an "ON symbol-OFF symbol-ON symbol-OFF symbol" waveform is to be generated, the target waveform can be set as x = [1, 1, …, 1, 0, 0, …, 0, 1, 1, …, 1, 0, 0, …, 0], or, That is, the part of the amplitude of the ON symbol is 1, and the part of the phase of the ON symbol can be inconsistent, as shown in FIG. 6. As shown in FIG. 7, DFT can be performed on x to obtain the frequency domain sequence y corresponding to x; then y is mapped to the frequency resource (such as the frequency resource corresponding to the wake-up signal); then IFFT is performed on the frequency domain signal; and a cyclic prefix (CP) is added to the signal after IFFT, and then a sequence to be sent x' is obtained (see the curve in FIG. 6). As can be seen from FIG. 6, the shapes of x and x' are similar, so at least two OOK symbols can be transmitted in the length of one OFDM symbol.

[0173] For the receiving end, one possible implementation can adopt the way of envelope detection or energy detection to receive the signal. For example, the signal received by the receiver (for distinction, referred to as OOK receiver) first passes through a matching network and a radio frequency (RF) filter to filter out the out-of-band noise / interference; then the frequency spectrum is moved to the baseband (BB) through a mixer, and the out-of-band noise / interference is further filtered out through a baseband filter; then the envelope detection / energy detection is performed on the signal (at this time, the value of the baseband signal is expressed as a real number in mathematics, only the amplitude without the phase), specifically, the OOK receiver can judge whether the received signal is an ON symbol or an OFF symbol by detecting the energy level in different time ranges, and then subsequent processing is performed.

[0174] In order to further improve the demodulation performance, a more advanced receiver can be considered, for example, a receiver with in-phase (I) / quadrature (Q) two paths (for distinction, referred to as OFDM receiver).

[0175] One possible implementation is that the signal received by the OFDM receiver first passes through a matching network and a radio frequency filter to filter out the out-of-band noise / interference; then the frequency spectrum is moved to the baseband through a mixer, and when the frequency spectrum is moved to the baseband, the I and Q two branches are distinguished (the corresponding mixing signals have a phase difference of pi / 2), and the signals on each branch pass through a baseband filter to further filter out the out-of-band noise / interference; then the two signals are combined together, at this time, the value of the baseband signal is expressed as a complex number in mathematics, both the amplitude and the phase; then the baseband signal is further processed.

[0176] When the OOK symbol mentioned above is received by an OFDM receiver, the OFDM receiver can further detect the sequence information inside the ON symbol of the OOK symbol, due to the capability of the OFDM receiver to detect the phase of the signal. For example, if the OFDM receiver can know in advance (e.g., predefined by the protocol, or the network device configures the relevant parameters to the terminal device in advance) the specific information of the sequence generating the ON symbol, the OFDM receiver can generate a local sequence based on the sequence generating the ON symbol, and then correlate the received signal with the local sequence, so as to reduce the influence of the noise (such as in-band noise) and / or interference that is not filtered out by the filter, and thus improve the demodulation performance. Alternatively, if there can be multiple sequences generating the ON symbol, the OFDM receiver can identify which sequence is transmitted by detection, so as to obtain more information. For example, assuming that there can be four sequences generating the ON symbol, and each sequence corresponds to the information {00, 01, 10, 11}, the OFDM receiver can obtain an additional 2-bit information by detecting which sequence is used. In this way, the data rate carried by the wake-up signal can be improved. The above method of “letting the OFDM receiver know the information of the sequence generating the OOK symbol, so as to improve the demodulation performance and / or improve the data rate” can be referred to as sequence on top of OOK or overlaid sequence over OOK.

[0177] 5. Monitoring of the wake-up signal: Before the terminal device starts to monitor the wake-up signal in the connected state, the network device will configure the relevant parameters of the wake-up signal. The configuration parameters of the wake-up signal may, for example, include at least one of the following: the time domain monitoring position (such as the monitoring occasion (MO)) of the wake-up signal, the frequency domain resource position of the wake-up signal, the signal length of the wake-up signal, the format of the wake-up signal, and the like. The time domain monitoring position of the wake-up signal refers to the time domain resource position for monitoring the wake-up signal, such as the wake-up signal occasion or the low-power wake-up signal occasion (LP-WUS occasion, LO). One LO may include one or more MOs, that is, the time domain monitoring position of the wake-up signal may include one or more MOs. The MO can also be referred to as the wake-up signal MO (LP-WUS MO). The MO can be the basic time unit (or time domain unit) when the wake-up circuit is working. One wake-up signal may occupy one or more MOs. The MO and the OFDM symbol are similar concepts, that is, the MO is a unit (such as the minimum unit) of time domain resource scheduling, that is, a time unit (or time domain unit) can be an MO. As an example, one MO includes one or more OOK symbols, or one MO includes one or more OFDM symbols, and the like.

[0178] 6. Discontinuous reception (DRX) mechanism: introduced mainly for power saving, network device can configure a DRX cycle for terminal device in radio resource control (RRC) connected state.

[0179] Referring to FIG. 8, as an example, FIG. 8 is a schematic diagram of a DRX cycle. As shown in FIG. 8, as an example, the DRX cycle is composed of an “on duration” part and an “opportunity for DRX” part. In the on duration time, the terminal device monitors and receives PDCCH, that is, the terminal device receives physical downlink control information (DCI) carried on PDCCH. In the opportunity for DRX time, the terminal device can not monitor or receive PDCCH to reduce power consumption. The DRX mechanism includes a discontinuous reception duration timer (drx-onDurationTimer), which needs to be started at the beginning of each DRX cycle (i.e., the beginning of the onDuration of each DRX cycle). When the drx-onDurationTimer expires, it indicates the end of the “onDuration” time, at which time the UE enters the “Opportunity for DRX” time.

[0180] As an example, the DRX mechanism includes at least one timer: drx-onDurationTimer, DRX inactivity timer (drx-InactivityTimer), retransmission timer (RetransmissionTimer).

[0181] 1) drx-onDurationTimer: at the beginning of each DRX cycle (i.e., the beginning of the “onDuration” of each DRX cycle), the drx-onDurationTimer can be started (e.g., the terminal device starts the drx-onDurationTimer). When the drx-onDurationTimer expires, it indicates the end of the “onDuration” time, that is, the terminal device enters the “opportunity for DRX” time.

[0182] 2) drx-InactivityTimer: When the terminal device receives a PDCCH indicating a new transmission, since the terminal device is likely to be scheduled by the network device in the following time, the terminal device can start the drx-InactivityTimer, and the terminal device monitors and receives the PDCCH in the running time of the drx-InactivityTimer.

[0183] 3) RetransmissionTimer: It can be divided into an uplink DRX retransmission timer (drx-RetransmissionTimerUL) and a DRX retransmission timer (drx-RetransmissionTimerDL). Since the network device can schedule the terminal device for retransmission in the running time of the RetransmissionTimer, the terminal device monitors and receives the PDCCH in the running time of the RetransmissionTimer.

[0184] In summary, the terminal device monitors and receives the PDCCH in the running time of the drx-onDurationTimer, the drx-InactivityTimer, the uplink drx-RetransmissionTimerUL, and the downlink drx-RetransmissionTimerDL, which can be referred to as the "Active Time" of the DRX, that is, the terminal device needs to wake up the main circuit to prepare to receive signaling and / or data. In the time outside the running time of the drx-onDurationTimer, the drx-InactivityTimer, the uplink drx-RetransmissionTimerUL, and the downlink drx-RetransmissionTimerDL, the terminal device can not need to monitor and receive the PDCCH, which can be referred to as the "sleep time" (or non-active time) of the DRX, that is, the terminal device can sleep in the "sleep time" of the DRX. The power consumption of the terminal device in the "Active Time" of the DRX is higher than that in the "sleep time" of the DRX. It should be noted that in other functions other than the DRX mechanism, the terminal device can be limited to be in the "Active Time" or the "sleep time" in some cases, which does not conflict with the DRX mechanism, but is a relationship of taking the union set. The above is an example for illustration, and this is not limited, for example, the "Active Time" can refer to the relevant description in the protocol.

[0185] 7、Channel information: information capable of reflecting channel characteristics and channel quality. As an example, the channel information is at least one of: channel state information (CSI), layer 1 (L1) reference signal receiving power (RSRP) (L1-RSRP), and the like.

[0186] Taking the network device obtaining the downlink CSI in the manner of uplink feedback by the terminal device as an example, specifically, the network device sends a downlink reference signal to the terminal device, and the terminal device receives the downlink reference signal; since the terminal device knows the sending information of the downlink reference signal, the terminal device can estimate (or measure) the downlink channel experienced by the downlink reference signal based on the received downlink reference signal, and then the terminal device can generate the CSI based on the measurement, and feed back the CSI to the network device.

[0187] As an example, the CSI includes at least one of: channel quality indication (CQI), precoding matrix indicator (PMI), rank indicator (RI), CSI-RS resource indicator (CRI), layer indicator (LI), signal to interference plus noise ratio (SINR), and the like. The signal to interference plus noise ratio can also be referred to as the signal to interference and noise ratio.

[0188] The embodiments of the present application mainly take CSI and L1-RSRP as examples for illustration, and this is not limited. For example, L1-RSRP can also be included in CSI or L1-RSRP can also be included in the CSI report (CSI report). For another example, the channel information can also include other information that can reflect channel characteristics and channel quality.

[0189] In addition, the periodic CSI and the periodic L1-RSRP are taken as examples for illustration in the embodiments of the present application. Taking the periodic CSI as an example, the periodic CSI means that after the network device configures the periodic CSI for the terminal device through signaling (such as RRC signaling), the terminal device starts the periodic measurement and reports the CSI based on the configuration of the network device.

[0190] A terminal device can be configured to report periodic CSI and / or L1-RSRP. In a DRX mechanism, the terminal device is periodically woken up at the time period indicated by onduration, and then can report periodic CSI and / or L1-RSRP in the time period indicated by onduration, so that the terminal device and the network device can know the channel state, beam quality, link quality, and the like between the two. However, when the terminal device monitors the wake-up signal, in order to save energy, the terminal device can not start the drx-OnDurationTimer to monitor the PDCCH periodically, that is, the terminal device does not wake up the main circuit. However, the main circuit of the terminal device is in a closed state for a long time, and the terminal device and the network device cannot know the channel state between the two, which can cause the terminal device to be unable to monitor the wake-up signal (and other downlink signals). For example, the channel state between the terminal device and the network device becomes poor, so that even if the network device sends a wake-up signal, the terminal device can not monitor the wake-up signal. Therefore, even if the terminal device is monitoring the wake-up signal, the network device can still configure the terminal device to report periodic CSI and / or L1-RSRP, such as configuring the terminal device to report periodic CSI and / or L1-RSRP at the location of onduration.

[0191] However, considering that the wake-up circuit and the main circuit of the terminal device can be difficult to work at the same time, when the terminal device measures the channel and reports the channel information through the main circuit, it is difficult to monitor the wake-up signal through the wake-up circuit.

[0192] Therefore, the embodiments of the present application propose a way that when the terminal device is monitoring the wake-up signal, if the network device configures the terminal device to measure and / or report channel information, the terminal device does not expect to monitor the wake-up signal at the corresponding location (such as the time domain resource location including measuring and / or reporting channel information), in other words, the terminal device can not (or be called to suspend, or be called to pause, or be called to stop, or be called to deactivate) monitor the wake-up signal. In this way, it can avoid requiring the terminal device to receive the wake-up signal and the PDCCH at the same time, and also can reduce the probability of the terminal device missing the wake-up signal.

[0193] The method provided by the embodiments of the present application will be described in detail below with reference to the drawings. The embodiments provided by the present application can be applied to the scenario shown in the above figures, without limitation. In addition, the terms involved below can refer to the previous explanations, which will not be repeated hereinafter. In addition, the following is described by taking a terminal device and a network device as examples for illustrative purposes. The terminal device can be replaced by a terminal device or a component (for example, a chip or a chip system or a circuit or a communication module) of the terminal device, and the network device can be replaced by a component (for example, a chip or a chip system or a circuit or a communication module) of the network device. In addition, the steps described below can also be divided into being executed by multiple execution subjects, which can be logically and / or physically separated.

[0194] Referring to FIG. 9, as an example, FIG. 9 is a schematic diagram of a communication method 900 provided by an embodiment of the present application. The method 900 shown in FIG. 9 can include the following steps.

[0195] S910, the terminal device receives first configuration information, and the first configuration information indicates a first time domain resource.

[0196] The first time domain resource is a time domain resource for monitoring a wake-up signal. The unit of the first time domain resource can be, for example, a MO, and the first time domain resource includes at least one MO.

[0197] The first configuration information can indicate the first time domain resource, in other words, the terminal device can know the position of the first time domain resource based on the first configuration information, that is, know the time domain position for monitoring the wake-up signal, which represents the position at which the terminal device can monitor the wake-up signal, that is, the embodiments of the present application do not limit the terminal device to always (or necessarily) monitor the wake-up signal at the time domain position. For example, if the time domain position includes multiple time domain units, the embodiments of the present application do not limit the terminal device to monitor the wake-up signal in each of the multiple time domain units.

[0198] As an example, the first configuration information includes at least one of the following parameters of the first time domain resource: a period, an offset.

[0199] The period, or the monitoring period of the wake-up signal, refers to how long a terminal device (or a group of terminal devices) monitors the wake-up signal every time. Taking a MO as an example, the first time domain resource includes multiple MOs, and the multiple MOs occur periodically, and each time the multiple MOs occur periodically, K MOs (as an example, the K MOs can be considered as one LO) are included, and for a certain terminal device or a group of terminal devices, the wake-up signal can be monitored in one or more of the K MOs, and K is an integer greater than 1 or equal to 1.

[0200] The offset, also referred to as a monitoring offset value, or a monitoring offset value of the wake-up signal, refers to an offset relative to a reference position in each monitoring period of the wake-up signal. The reference position can be a starting position, or can also be a specific moment of system time (for example, OFDM symbol #0 of slot #0 of subframe #0 in frame #0), which is not limited. The network device can configure different offsets for different terminal devices (or groups of terminal devices), so as to stagger the time domain monitoring positions of different terminal devices (or groups of terminal devices), thereby avoiding congestion or conflict of wake-up signals of too many terminal devices.

[0201] As an example, the first configuration information is received by the terminal device through the main circuit, that is, the terminal device receives the first configuration information through the main circuit in S910. As an example, the first configuration information is carried in any of the following: medium access control (MAC) signaling (for example, MAC control element (MAC CE / MAC-CE)), downlink control information (DCI), radio resource control (RRC) signaling, and the like.

[0202] It can be understood that in the embodiments of the present application, the configuration information carried in multiple signaling can mean that multiple information contained in the configuration information is respectively carried in different signaling, or different contents of the same information are respectively carried in different signaling, or the same information is carried in different signaling. This will not be described below.

[0203] S920, the terminal device receives second configuration information, and the second configuration information indicates to measure and / or report channel information in a second time domain resource.

[0204] The second time domain resource is associated with a time period indicated by the drx-onDurationTimer, or the second time domain resource is related to the position of the onDuration. The starting position of the time period indicated by the drx-onDurationTimer is the starting position of the onDuration, and the length of the time period indicated by the drx-onDurationTimer is the time length of the onDuration.

[0205] For example, the second time domain resource is the time period indicated by the drx-onDurationTimer, that is, the terminal device measures and / or reports channel information in the time period indicated by the drx-onDurationTimer.

[0206] For another example, the second time-domain resource is a time period indicated by the drx-onDurationTimer, i.e., the terminal device measures and / or reports the channel information in the time period indicated by the drx-onDurationTimer, and the time period indicated by the drx-onDurationTimer is outside the Active Time.

[0207] For another example, the second time-domain resource is a time period indicated by the drx-onDurationTimer, i.e., the terminal device measures and / or reports the channel information in the time period indicated by the drx-onDurationTimer, and the time period indicated by the drx-onDurationTimer is outside the Active Time.

[0208] As an example, the channel information includes at least one of the following: CSI, L1-RSRP. For example, the channel information can be periodic CSI; for another example, the channel information can be periodic L1-RSRP; for another example, the channel information can be periodic CSI and periodic L1-RSRP. The description of the channel information can refer to the description in the previous term explanation part.

[0209] As an example, the second configuration information is received by the terminal device through the main circuit, i.e., the terminal device receives the second configuration information through the main circuit in S920. As an example, the second configuration information is carried in at least one of the following: MAC signaling (for example, MAC CE), DCI, RRC signaling, etc.

[0210] Optionally, the second configuration information indicates to measure and / or report the channel information in the second time-domain resource, including: the second configuration information indicates to measure and / or report periodic channel information in the second time-domain resource, in other words, the second configuration information indicates to measure and / or report the periodic channel information in the second time-domain resource. The following takes CSI and L1-RSRP as examples to introduce several possible implementation manners.

[0211] The first possible implementation manner is that the second configuration information indicates to measure and / or report periodic CSI in the second time-domain resource.

[0212] Example 1, the second configuration information indicates to report periodic CSI in the second time domain resource. In other words, the second configuration information indicates to report periodic CSI in the second time domain resource. Assuming that the period of reporting CSI is T1, the terminal device can know, based on the second configuration information, that CSI is reported every T1 in the second time domain resource. T1 is a number greater than 0.

[0213] Example 2, the second configuration information indicates to measure periodic CSI in the second time domain resource. In other words, the second configuration information indicates to measure periodic CSI in the second time domain resource. Assuming that the period of measuring CSI is T2, the terminal device can know, based on the second configuration information, that CSI is measured every T2 in the second time domain resource. T2 is a number greater than 0.

[0214] Example 3, the second configuration information indicates to measure and report periodic CSI in the second time domain resource. In other words, the second configuration information indicates to measure and report periodic CSI in the second time domain resource. Assuming that the period of reporting CSI is T1 and the period of measuring CSI is T2, the terminal device can know, based on the second configuration information, that CSI is measured every T2 and reported every T1 in the second time domain resource. T1 and T2 can be the same or T1 is greater than T2, which is not limited.

[0215] The second possible implementation manner, the second configuration information indicates to measure and / or report periodic L1-RSRP in the second time domain resource.

[0216] Example 1, the second configuration information indicates to report periodic L1-RSRP in the second time domain resource. In other words, the second configuration information indicates to report periodic L1-RSRP in the second time domain resource. Assuming that the period of reporting L1-RSRP is T3, the terminal device can know, based on the second configuration information, that L1-RSRP is reported every T3 in the second time domain resource. T3 is a number greater than 0.

[0217] Example 2, the second configuration information indicates to measure periodic L1-RSRP in the second time domain resource. In other words, the second configuration information indicates to measure periodic L1-RSRP in the second time domain resource. Assuming that the period of measuring L1-RSRP is T4, the terminal device can know, based on the second configuration information, that L1-RSRP is measured every T4 in the second time domain resource. T4 is a number greater than 0.

[0218] In Example 3, the second configuration information indicates to measure and report periodic L1-RSRP in the second time-domain resource. In other words, the second configuration information indicates to measure L1-RSRP periodically in the second time-domain resource and report the L1-RSRP. Assuming that the period of reporting L1-RSRP is T3 and the period of measuring L1-RSRP is T4, the terminal device can know, based on the second configuration information, that L1-RSRP is measured every T4 in the second time-domain resource and reported every T3. T3 and T4 can be the same or T3 can be greater than T4, which is not limited herein.

[0219] In a third possible implementation, the second configuration information indicates to measure and / or report periodic CSI in the second time-domain resource and measure and / or report periodic L1-RSRP in the second time-domain resource. This implementation can refer to the above two implementations, which will not be repeated here.

[0220] In S930, the terminal device monitors the wake-up signal in the time-domain resource that does not overlap with the third time-domain resource in the first time-domain resource.

[0221] In other words, the terminal device does not monitor the wake-up signal in the third time-domain resource, or in other words, the terminal device determines not to monitor the wake-up signal in the third time-domain resource.

[0222] Optionally, in one possible case, the method 900 further includes that the terminal device does not monitor the PDCCH in the third time-domain resource, or in other words, the terminal device determines not to monitor the PDCCH in the third time-domain resource. Based on this, the terminal device does not monitor the wake-up signal and the PDCCH in the third time-domain resource.

[0223] Alternatively, in another possible case, the method 900 further includes that the terminal device monitors the PDCCH in the third time-domain resource. Based on this, the terminal device monitors the PDCCH and does not monitor the wake-up signal in the third time-domain resource.

[0224] In the time domain, the third time domain resource can be understood as a subset of the first time domain resource, in other words, the first time domain resource includes the third time domain resource and other time domain resources (for distinction, the time domain resources in the first time domain resource other than the third time domain resource are referred to as fourth time domain resources). Specifically, the terminal device determines the location of the first time domain resource based on the first configuration information, and the third time domain resource is originally a time domain resource for monitoring the wake-up signal (that is, the first time domain resource originally includes the third time domain resource, or in other words, the third time domain resource is originally a subset of the first time domain resource); the terminal device determines to measure and / or report channel information in the second time domain resource based on the second configuration information; therefore, the terminal device monitors the wake-up signal in the first time domain resource, and does not monitor the wake-up signal in the third time domain resource, that is, the terminal device does not expect to monitor the wake-up signal in the third time domain resource. Based on this, it can be known that the terminal device originally monitors the wake-up signal in the first time domain resource, and because of measuring and / or reporting channel information in the second time domain resource, the terminal device determines the third time domain resource based on the second time domain resource, and then does not monitor the wake-up signal in the third time domain resource, that is, monitors the wake-up signal in the fourth time domain resource.

[0225] It can be understood that the terminal device mentioned in the embodiments of the present application in the time domain resource (such as the first time domain resource, and such as the fourth time domain resource, etc.) does not limit the terminal device to always monitor the wake-up signal in the time domain resource, but means that the terminal device monitors the wake-up signal in part or all of the time domain positions in the time domain resource.

[0226] In the third time domain resource, the wake-up signal can be replaced by any one of the following: stopping monitoring the wake-up signal in the third time domain resource, suspending monitoring the wake-up signal in the third time domain resource, deactivating the wake-up signal monitoring in the third time domain resource. For unified description, the following are described by taking the wake-up signal not being monitored in the third time domain resource as an example.

[0227] Among them, the third time domain resource is determined according to the second time domain resource, in other words, the third time domain resource is associated with the second time domain resource. The following introduces several possible implementation manners of the third time domain resource.

[0228] The first possible implementation manner is that the third time domain resource is the second time domain resource. Taking the time period indicated by the drx-onDurationTimer as an example, in other words, the third time domain resource is the time period indicated by the drx-onDurationTimer, or in other words, the third time domain resource is the time domain resource in which the time period indicated by the drx-onDurationTimer is located. It should be understood that in this case, the foregoing step of determining the third time domain resource according to the second time domain resource can be omitted.

[0229] Referring to FIG. 10, as an example, FIG. 10 is a schematic diagram of the third time domain resource according to an embodiment of the present application. As shown in FIG. 10, the third time domain resource is located at the same position as the onDuration, that is, the third time domain resource is the time period indicated by the drx-onDurationTimer. It should be understood that, in the embodiments of the present application, the position of the onDuration (or simply referred to as onDuration) is only used to describe the position of the onDuration time, and does not mean that the drx-onDurationTimer will definitely run.

[0230] In a second possible implementation, the third time domain resource is a partial time domain resource of the second time domain resource. Taking the time period indicated by the drx-onDurationTimer as an example, in other words, the third time domain resource is a partial time domain resource of the time domain resource in which the time period indicated by the drx-onDurationTimer is located (for ease of description, this partial time domain resource is referred to as time domain resource #A).

[0231] Referring to FIGS. 11-13, as an example, FIGS. 11-13 are another schematic diagram of the third time domain resource according to an embodiment of the present application. As shown in FIGS. 11-13, the third time domain resource is a partial time domain resource in the onDuration, that is, the third time domain resource is a partial time domain resource of the time domain resource in which the time period indicated by the drx-onDurationTimer is located, in other words, the length of the third time domain resource is less than the length of the time period indicated by the drx-onDurationTimer.

[0232] Optionally, the time domain resource #A includes at least one of the following: a time domain resource of a reference signal, a time domain resource of an uplink channel. In other words, the third time domain resource includes at least one of the following: a time domain resource of a reference signal, a time domain resource of an uplink channel.

[0233] The reference signal is used for measuring channel information, that is, the reference signal is a reference signal used for measuring channel information. The time domain resource of the reference signal refers to the time domain resource occupied by the reference signal. The reference signal is a downlink reference signal, and as an example, the reference signal is at least one of the following: a channel state information reference signal (CSI-RS), a synchronization signal block (SSB).

[0234] The uplink channel is used for reporting channel information, that is, the uplink channel is a channel used for reporting channel information. The time domain resource of the uplink channel indicates a time domain resource occupied by the uplink channel. As an example, the uplink channel is at least one of the following: a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH).

[0235] Several examples are described below.

[0236] Example 1, the network device configures the third time domain resource.

[0237] Specifically, the network device can configure one or more time windows for the terminal device, and the one or more time windows are the third time domain resource, that is, the third time domain resource can be one or more time windows. The time window can be replaced by any of the following: time period, time interval, time domain resource. For brevity, it is uniformly described as a time window below.

[0238] The third time domain resource includes the time domain resource of the reference signal and / or the time domain resource of the uplink channel. For example, the network device can make the time domain resource of the uplink channel covered in the third time domain resource, so that the terminal device does not monitor the wake-up signal in the third time domain resource, that is, the terminal device can report channel information in the time domain resource of the uplink channel in the third time domain resource. As another example, the network device can make the time domain resource of the reference signal and the time domain resource of the uplink channel covered in the third time domain resource, so that the terminal device does not monitor the wake-up signal in the third time domain resource, that is, the terminal device can receive the reference signal on the time domain resource of the reference signal in the third time domain resource, and report channel information based on the measurement of the reference signal in the time domain resource of the uplink channel.

[0239] Optionally, the method 900 further includes: the network device sends fourth configuration information to the terminal device, the fourth configuration information indicating the third time domain resource, that is, the fourth configuration information indicating one or more time windows described above. As an example, the fourth configuration information includes at least one of the following: the starting position of the third time domain resource, the time length of the third time domain resource, the end position of the third time domain resource. The following describes two cases.

[0240] Case 1, the third time domain resource is one time window, that is, the third time domain resource is a continuous time domain resource.

[0241] As shown in (a) of FIG. 11, the third time domain resource can be a continuous time domain resource in the onDuration. In this case, the network device can indicate, to the terminal device, at least one of a start position of the third time domain resource, a time length of the third time domain resource, and an end position of the third time domain resource, so that the terminal device can determine the third time domain resource based on the at least one.

[0242] For example, the fourth configuration information includes the start position of the third time domain resource and the time length of the third time domain resource, so that the terminal device can determine the third time domain resource based on the start position of the third time domain resource and the time length of the third time domain resource.

[0243] For another example, the fourth configuration information includes the end position of the third time domain resource and the time length of the third time domain resource, so that the terminal device can determine the third time domain resource based on the end position of the third time domain resource and the time length of the third time domain resource.

[0244] For another example, the fourth configuration information includes the start position of the third time domain resource and the end position of the third time domain resource, so that the terminal device can determine the third time domain resource based on the start position of the third time domain resource and the end position of the third time domain resource.

[0245] For another example, the fourth configuration information includes the time length of the third time domain resource, so that the terminal device can determine the third time domain resource based on the time length of the third time domain resource and the start position or the end position of the third time domain resource. For example, the start position of the third time domain resource is the start position of the onDuration; or for another example, the end position of the third time domain resource is the end position of the onDuration.

[0246] The above is some examples, and the embodiments of the present application are not limited thereto.

[0247] In case 2, the third time domain resource is a plurality of time windows, that is, the third time domain resource is a plurality of continuous time domain resources.

[0248] As shown in (b) of FIG. 11, the third time domain resource can be a plurality of time windows in the onDuration. In this case, the network device can indicate, to the terminal device, at least one of a start position, a time length, and an end position of each time window in the third time domain resource, so that the terminal device can determine each time window based on the at least one, and further determine the third time domain resource. For details, refer to the related description in case 1 above, which will not be described here.

[0249] Alternatively, if the multiple time windows in the third time domain resource are periodically present, the fourth configuration information can further indicate at least one of the following parameters of the multiple time windows: a period, an offset value, a length of the time window, etc., so that the terminal device can determine the time windows based on the fourth configuration information.

[0250] Example 1 is introduced above, and example 2 is introduced below.

[0251] In example 2, the network device configures the time domain resource of the uplink channel and / or the time domain resource of the reference signal, and the third time domain resource includes the time domain resource of the uplink channel and / or the time domain resource of the reference signal.

[0252] As shown in FIG. 12, the network device configures the time domain resource of the reference signal (such as CSI-RS) and the time domain resource of the uplink channel (such as PUCCH), which can be the third time domain resource. It should be understood that although only two continuous time domain resources are shown in FIG. 12, the present application is not limited thereto, and the time domain resource of the uplink channel and the time domain resource of the reference signal included in the third time domain resource can each be multiple continuous time domain resources.

[0253] Optionally, the method 900 further includes: the network device sending third configuration information to the terminal device, the third configuration information indicating the time domain resource of the reference signal and / or the time domain resource of the uplink channel. No wake-up signal is monitored on the time domain resource of the reference signal and / or the time domain resource of the uplink channel. As an example, the time domain resource of the reference signal and / or the time domain resource of the uplink channel on which no wake-up signal is monitored can be predefined, so that the terminal device can learn the time domain resource of the reference signal and / or the time domain resource of the uplink channel after receiving the third configuration information, and based on the predefinition, the time domain resource indicated by the third configuration information on which no wake-up signal is monitored.

[0254] The following describes several cases.

[0255] In case 1, the network device configures the time domain resource of the uplink channel, and the third time domain resource includes the time domain resource of the uplink channel.

[0256] Further optionally, the third time domain resource further includes: a fourth time domain resource located before the time domain resource of the uplink channel, and / or a fifth time domain resource located after the time domain resource of the uplink channel. The end position of the fourth time domain resource is the start position of the time domain resource of the uplink channel, and the start position of the fifth time domain resource is the end position of the time domain resource of the uplink channel.

[0257] As shown in (a) of FIG. 13, taking the uplink channel as the PUCCH for example, the third time domain resource includes the time domain resource of the PUCCH, the fourth time domain resource, and the fifth time domain resource. The length of the third time domain resource is greater than the length of the time domain resource of the PUCCH. The starting position of the third time domain resource is located before the starting position of the time domain resource of the PUCCH, assuming that the interval between the starting position of the third time domain resource and the starting position of the time domain resource of the PUCCH is k1, k1 can represent the time for the terminal device to switch from the wake-up circuit to the main circuit, and k1 is greater than 0. The ending position of the third time domain resource is located after the ending position of the time domain resource of the PUCCH, assuming that the interval between the ending position of the third time domain resource and the ending position of the time domain resource of the PUCCH is k2, k2 can represent the time for the terminal device to switch from the main circuit to the wake-up circuit, and k2 is greater than 0. k1 and k2 can be the same or different, which is not limited.

[0258] In case 2, the network device configures the time domain resource of the reference signal, and the third time domain resource includes the time domain resource of the reference signal.

[0259] Further optionally, the third time domain resource further includes: a sixth time domain resource located before the time domain resource of the reference signal, and / or a seventh time domain resource located after the time domain resource of the reference signal. The ending position of the sixth time domain resource is the starting position of the time domain resource of the reference signal, and the starting position of the seventh time domain resource is the ending position of the time domain resource of the reference signal.

[0260] As shown in (b) of FIG. 13, taking the reference signal as the CSI-RS for example, the third time domain resource includes the time domain resource of the CSI-RS, the sixth time domain resource, and the seventh time domain resource. The length of the third time domain resource is greater than the length of the time domain resource of the CSI-RS. The starting position of the third time domain resource is located before the starting position of the time domain resource of the CSI-RS, assuming that the interval between the starting position of the third time domain resource and the starting position of the time domain resource of the CSI-RS is k3, k3 can represent the time for the terminal device to switch from the wake-up circuit to the main circuit, and k3 is greater than 0. The ending position of the third time domain resource is located after the ending position of the time domain resource of the CSI-RS, assuming that the interval between the ending position of the third time domain resource and the ending position of the time domain resource of the CSI-RS is k4, k4 can represent the time for the terminal device to switch from the main circuit to the wake-up circuit, and k4 is greater than 0. k3 and k4 can be the same or different, which is not limited.

[0261] In case 3, the network device configures the time domain resource of the uplink channel and the time domain resource of the reference signal, and the third time domain resource includes the time domain resource of the uplink channel and the time domain resource of the reference signal.

[0262] Further optionally, the third time domain resource further comprises: a fourth time domain resource located before the time domain resource of the uplink channel and / or a fifth time domain resource located after the time domain resource of the uplink channel, and a sixth time domain resource located before the time domain resource of the reference signal and / or a seventh time domain resource located after the time domain resource of the reference signal.

[0263] As shown in (c) of FIG. 13, taking the reference signal as a CSI-RS and the uplink channel as a PUCCH as an example, the third time domain resource comprises the time domain resource of the PUCCH, the fourth time domain resource, the fifth time domain resource, the sixth time domain resource, and the seventh time domain resource. The length of the third time domain resource is greater than the sum of the length of the time domain resource of the CSI-RS and the length of the time domain resource of the PUCCH. The third time domain resource comprises two segments of time domain resources, which can be discontinuous. One segment of time domain resources (referred to as time domain resource #1) has a starting position located before the starting position of the time domain resource of the CSI-RS, an ending position located after the ending position of the time domain resource of the CSI-RS, an interval between the starting position of the time domain resource #1 and the starting position of the time domain resource of the CSI-RS being k3, and an interval between the ending position of the time domain resource #1 and the ending position of the time domain resource of the CSI-RS being k4. The other segment of time domain resources (referred to as time domain resource #2) has a starting position located before the starting position of the time domain resource of the PUCCH, an ending position located after the ending position of the time domain resource of the PUCCH, an interval between the starting position of the time domain resource #2 and the starting position of the time domain resource of the PUCCH being k1, and an interval between the ending position of the time domain resource #2 and the ending position of the time domain resource of the PUCCH being k2. For k1, k2, k3, and k4, refer to the foregoing description.

[0264] The above describes several possible scenarios in combination with FIG. 13, which are not limited thereto. For example, taking (a) of FIG. 13 as an example, the time domain resource of the PUCCH can comprise multiple segments of continuous time domain resources. In this case, the third time domain resource satisfies at least one of the following: the length of the third time domain resource is greater than the sum of the lengths of the time domain resources of the uplink channel, the starting position of the third time domain resource is located before the starting position of the first segment of time domain resources of the uplink channel, and the ending position of the third time domain resource is located after the ending position of the last segment of time domain resources of the uplink channel. Other similar cases are not described herein.

[0265] Optionally, the method 900 further comprises: measuring and / or reporting, by the terminal device, channel information in the third time domain resource.

[0266] For example, the third time domain resource comprises the time domain resource of the uplink channel, and the terminal device transmits the measured channel information on the time domain resource of the uplink channel.

[0267] For another example, the third time-domain resource comprises a time-domain resource of a reference signal, the terminal device receives the reference signal on the time-domain resource of the reference signal, and then performs measurement based on the reference signal to obtain channel information.

[0268] For another example, the third time-domain resource comprises a time-domain resource of an uplink channel and a time-domain resource of a reference signal, the terminal device receives the reference signal on the time-domain resource of the reference signal, and then performs measurement based on the reference signal to obtain channel information, and transmits the channel information on the time-domain resource of the uplink channel.

[0269] Further optionally, the terminal device monitors the wake-up signal through a first circuit, and measures and / or reports the channel information through a second circuit. The energy consumption of the first circuit is lower than that of the second circuit. The first circuit is, for example, a wake-up circuit, and the second circuit is, for example, a main circuit.

[0270] The above mainly introduces the relationship between the measurement and / or reporting of the channel information by the terminal device and the monitoring of the wake-up signal by the terminal device. The following describes the related configuration of the time-domain resource of the wake-up signal in combination with FIG. 14 to FIG. 17. It can be understood that the embodiments described below can be used in combination with the embodiments of the method 900 described above, or can be used alone, and the present disclosure is not limited in this regard. Before starting to describe the specific schemes, two schemes are first described.

[0271] Scheme A: The terminal device monitors the wake-up signal at a position before the onDuration of the DRX. The wake-up signal can be used to trigger the start of the drx-OnDurationTimer. Accordingly, if the network device wants to send the wake-up signal, the network device can send the wake-up signal at the position, so that the terminal device and the network device can align the time-domain resource position of the wake-up signal. Since the wake-up signal triggers the start of the drx-OnDurationTimer, and the terminal device and the network device have a common understanding of the time-domain position of the start of the drx-OnDurationTimer, the terminal device and the network device can also align the time-domain resource position of the PDCCH monitored by the terminal device (i.e., the PDCCH that can be sent by the network device) after the wake-up signal.

[0272] In the scheme B, the terminal device monitors the wake-up signal at any possible position outside the Active Time, and the specific positions at which the terminal device monitors the wake-up signal can be determined by the terminal device based on the configuration of the network device. For example, the network device configures a period and / or an offset, and the terminal device determines the positions at which the terminal device monitors the wake-up signal based on the period and / or the offset. The period and / or the offset can be irrelevant to the configuration parameters of the DRX. The wake-up signal monitored by the terminal device based on the scheme B can be used to trigger the start of a timer (for example, a second timer), and during the running of the second timer, the terminal device can monitor the PDCCH. In the scheme B, the terminal device and the network device can also be aligned at the time point at which the second timer starts after the wake-up signal, and thus the terminal device and the network device can be aligned at the time domain resource position at which the terminal device monitors the PDCCH (that is, the network device can send the PDCCH) after the wake-up signal.

[0273] In view of the fact that the network device can configure the terminal device with the above-described scheme A and scheme B, embodiments of the present application propose some manners. In one possible implementation manner, the time domain units used for monitoring the wake-up signal in the scheme B can be used as a reference, and then the time domain units used for monitoring the wake-up signal in the scheme A can be determined (or configured). In another possible implementation manner, the network device can configure the time domain units used for monitoring the wake-up signal in the scheme A and the scheme B respectively. Through the above manners, the configuration of the network device on the above-described scheme A and scheme B and the operation of the terminal device after monitoring the wake-up signal can be implemented. The two possible implementation manners will be introduced below in combination with the method 1400 and the method 1600 respectively.

[0274] Referring to FIG. 14, for example, FIG. 14 is a schematic diagram of a communication method 1400 provided by an embodiment of the present application. The method 1400 shown in FIG. 14 can include the following steps.

[0275] In S1410, the terminal device receives configuration information #1, and the configuration information #1 indicates N time domain units, and the N time domain units are time domain units used for monitoring the wake-up signal, and N is an integer greater than 1.

[0276] For example, one time domain unit is any one of the following: one OOK symbol, one OFDM symbol, one slot, one mini-slot, one partial slot, one subframe, one frame, one MO, and the like.

[0277] As an example, the N time-domain units occur periodically, in other words, the interval between each two adjacent time-domain units in the N time-domain units is the same.

[0278] Optionally, the configuration information #1 comprises a period of the N time-domain units and / or an offset of the N time-domain units. The period of the N time-domain units, or in other words, the monitoring period of the wake-up signal, refers to how long the terminal device (or the terminal device group) monitors the wake-up signal every time. The offset of the N time-domain units, or in other words, the monitoring offset value or the monitoring offset value of the wake-up signal, refers to the offset relative to the reference position in each monitoring period of the wake-up signal. The reference position can be the starting position, or can also be a specific time of the system time (e.g., OFDM symbol #0 of slot #0 of subframe #0 in frame #0), which is not limited. The network device can configure different offsets for different terminal devices (or terminal device groups) to stagger the time-domain monitoring positions of different terminal devices (or terminal device groups), so as to avoid congestion or conflict of the wake-up signals of too many terminal devices.

[0279] As an example, the configuration information #1 is received by the terminal device through the main circuit, that is, the terminal device receives the configuration information #1 through the main circuit in S1410. As an example, the configuration information #1 is carried in at least one of the following: MAC signaling (e.g., MAC CE), DCI, RRC signaling, etc.

[0280] S1420, if the terminal device monitors the wake-up signal in the time-domain unit that does not overlap with the time window in the N time-domain units, the second operation is performed.

[0281] Optionally, the method 1400 further comprises S1430, if the terminal device monitors the wake-up signal in the time-domain unit that overlaps with the time window in the N time-domain units, the first operation is performed.

[0282] The time window is associated with the duration onDuration, in other words, the time window can be determined based on the onDuration, for example, the end position of the time window is located before the start position of the time period indicated by the onDuration. The time window can be replaced by any of the following: time period, time interval, time-domain resource, W time-domain units, etc., W is an integer greater than 1 or equal to 1. Hereinafter, the time window is described uniformly.

[0283] The specific way of determining the time-domain unit (referred to as time-domain unit #A) that does not overlap with the time window in the N time-domain units by the terminal device, and the time-domain unit (referred to as time-domain unit #B) that overlaps with the time window in the N time-domain units by the terminal device is not limited. Hereinafter, two ways are briefly introduced.

[0284] In a possible implementation, after determining the N time domain units based on the configuration information #1, the terminal device can determine the time domain unit #B in combination with the time window, and the time domain units other than the time domain unit #B in the N time domain units are time domain units #A. As an example, the terminal device can determine the position of the time window based on the configuration information #2, which is described below.

[0285] In another possible implementation, after determining the N time domain units based on the configuration information #1, the terminal device can determine the time domain unit #B in combination with the onDuration, and the time domain units other than the time domain unit #B in the N time domain units are time domain units #A. For example, the time domain unit #B is a position before the start position of the time period indicated by the onDuration, and the time interval between the time domain unit #B and the start position of the time period indicated by the onDuration is L, where L is a number greater than 0. L can be indicated by the network device or can be predefined, which is not limited.

[0286] Optionally, the method 1400 further includes that the terminal device receives configuration information #2, and the configuration information #2 indicates the time window. In other words, the terminal device can determine the position of the time window based on the configuration information #2.

[0287] As an example, the configuration information #2 includes at least one of the following: a start position of the time window, a time length of the time window, an end position of the time window, and an offset between the time window and the onDuration. The offset between the time window and the onDuration can be an offset between the start position of the time window and the start position of the onDuration, or can be an offset between the end position of the time window and the start position of the onDuration, or can be an offset between the start position of the time window and the end position of the onDuration, or can be an offset between the end position of the time window and the end position of the onDuration.

[0288] For example, the configuration information #2 includes the start position of the time window and the time length of the time window, so that the terminal device can determine the time window based on the start position of the time window and the time length of the time window.

[0289] For another example, the configuration information #2 includes the end position of the time window and the time length of the time window, so that the terminal device can determine the time window based on the end position of the time window and the time length of the time window.

[0290] For another example, the configuration information #2 includes the start position of the time window and the end position of the time window, so that the terminal device can determine the time window based on the start position of the time window and the end position of the time window.

[0291] For another example, the configuration information #2 includes an offset between the time window and the onDuration, so that the terminal device determines the time window based on the offset between the time window and the onDuration and the time period indicated by the onDuration. For example, the time length of the time window can be predefined.

[0292] The above is some examples, and the embodiments of the present application are not limited thereto, as long as the time window can be determined.

[0293] For example, the configuration information #2 is received by the terminal device through the main circuit, that is, the terminal device receives the configuration information #2 through the main circuit. For example, the configuration information #2 is carried in at least one of the following: MAC signaling (for example, MAC CE), DCI, RRC signaling, etc.

[0294] As described above, the network device can configure the terminal device with the time domain unit for monitoring the wake-up signal through the scheme A and the scheme B. For example, the time domain unit for monitoring the wake-up signal in the scheme A can be the time domain unit of the N time domain units that overlaps with the time window, the time domain unit for monitoring the wake-up signal in the scheme B can be the time domain unit of the N time domain units that does not overlap with the time window, or the time domain unit for monitoring the wake-up signal in the scheme B can include the time domain unit of the N time domain units that does not overlap with the time window and the time domain unit of the N time domain units that overlaps with the time window.

[0295] Referring to FIG. 15, for example, FIG. 15 is a schematic diagram of the time domain unit for monitoring the wake-up signal provided by the embodiments of the present application. As shown in FIG. 15, the N time domain units are periodically present, for example, the interval between each adjacent two time domain units is T5.

[0296] As shown in (a) of FIG. 15, the time domain unit of the N time domain units that overlaps with the time window can be referred to as the first time domain unit, that is, for example, if the terminal device monitors the wake-up signal on the time domain unit of the N time domain units that overlaps with the time window, the first operation is performed. The time domain unit of the N time domain units that does not overlap with the time window can be referred to as the second time domain unit, that is, if the terminal device monitors the wake-up signal on the time domain unit of the N time domain units that does not overlap with the time window, the second operation is performed.

[0297] As shown in (b) of FIG. 15, the time domain units that overlap with the time window in the N time domain units can be referred to as first time domain units, or can also be referred to as second time domain units, that is, if the terminal device monitors the wake-up signal on the time domain units that overlap with the time window in the N time domain units, the first operation can be performed, or the second operation can be performed. The time domain units that do not overlap with the time window in the N time domain units can be referred to as second time domain units, that is, if the terminal device monitors the wake-up signal on the time domain units that do not overlap with the time window in the N time domain units, the second operation is performed.

[0298] As can be seen from the above, in some cases, as shown in (b) of FIG. 15, the first time domain units and the second time domain units overlap, and when the terminal device monitors the wake-up signal on the time domain units that overlap with the time window in the N time domain units, the first operation can be performed, or the second operation can be performed. The following introduces several possible implementation manners of the terminal device determining which operation to perform.

[0299] In a possible implementation manner, the terminal device determines to perform the first operation or the second operation based on whether the time window is configured.

[0300] For example, if the network device configures the time window, such as if the terminal device receives the configuration information #2, when the terminal device monitors the wake-up signal on the time domain units that overlap with the time window, the first operation is performed; if the network device does not configure the time window, such as if the terminal device does not receive the configuration information #2, the terminal device determines to perform the second operation when the terminal device monitors the wake-up signal on the time domain units that overlap with the time window. Based on this, the following two cases are included.

[0301] In a possible case, in step S1430, if the terminal device monitors the wake-up signal on the time domain units that overlap with the time window in the N time domain units, the first operation is performed, including: if the terminal device monitors the wake-up signal on the time domain units that overlap with the time window in the N time domain units, and the time window is configured, the first operation is performed.

[0302] In another possible case, the method 1400 further includes: if the terminal device determines that the time window is not configured, such as if the terminal device does not receive the configuration information #2, the terminal device performs the second operation when the terminal device monitors the wake-up signal on the N time domain units. In this case, the method 1400 includes steps S1410 and S1420, and S1420 can be replaced with: the terminal device performs the second operation when the terminal device monitors the wake-up signal on the N time domain units.

[0303] In another possible implementation manner, the terminal device determines to perform the first operation or the second operation based on information carried in the wake-up signal.

[0304] For example, if the terminal device monitors the wake-up signal on the time domain unit overlapping with the time window, and the wake-up signal carries the first information, the terminal device performs the first operation; if the terminal device monitors the wake-up signal on the time domain unit overlapping with the time window, and the wake-up signal carries the second information, the terminal device performs the second operation. Based on this, the following two cases are included.

[0305] In a possible case, in step S1430, if the terminal device monitors the wake-up signal on the time domain unit overlapping with the time window in the N time domain units, the first operation is performed, including: if the terminal device monitors the wake-up signal on the time domain unit overlapping with the time window in the N time domain units, and the wake-up signal carries the first information, the first operation is performed.

[0306] In another possible case, the method 1400 further includes: if the terminal device monitors the wake-up signal on the time domain unit overlapping with the time window in the N time domain units, and the wake-up signal carries the second information, the second operation is performed. In this case, the method 1400 includes steps S1410 and S1420, and S1420 can be replaced with: the terminal device performs the second operation when the wake-up signal is monitored on the N time domain units.

[0307] The first information and the second information are different. As an example, the first information and the second information are in the form of code points. Specifically, the code point (or code point value, or identification (ID)) is included in the wake-up signal, which can be used by the terminal device to determine whether to perform the first operation or the second operation.

[0308] In another possible implementation, the terminal device determines to perform the first operation or the second operation based on priority information.

[0309] The priority information can be indicated by the network device, or can be predefined, which is not limited.

[0310] For example, if the priority information indicates that the priority of the first operation is higher than the priority of the second operation, or the priority of scheme A is higher than the priority of scheme B, the terminal device performs the first operation when the wake-up signal is monitored on the time domain unit overlapping with the time window; if the priority information indicates that the priority of the second operation is higher than the priority of the first operation, or the priority of scheme B is higher than the priority of scheme A, the terminal device performs the second operation when the wake-up signal is monitored on the time domain unit overlapping with the time window. Based on this, the following two cases are included.

[0311] In a possible scenario, in step S1430, if the terminal device monitors the wake-up signal on the time domain unit that overlaps with the time window in the N time domain units, the first operation is performed, including: if the terminal device monitors the wake-up signal on the time domain unit that overlaps with the time window in the N time domain units, and the priority of the first operation is higher than the priority of the second operation, the first operation is performed.

[0312] In another possible scenario, the method 1400 further includes: if the terminal device monitors the wake-up signal on the time domain unit that overlaps with the time window in the N time domain units, and the priority of the second operation is higher than the priority of the first operation, the second operation is performed. In this scenario, the method 1400 includes steps S1410 and S1420, and S1420 can be replaced with: the terminal device performs the second operation when the terminal device monitors the wake-up signal on the N time domain units.

[0313] In another possible implementation, the first operation or the second operation is predefined.

[0314] For example, the following is predefined: the priority of the first operation is higher than the priority of the second operation, the priority of the scheme A is higher than the priority of the scheme B, the terminal device performs the first operation when the terminal device monitors the wake-up signal on the time domain unit that overlaps with the time window, and the terminal device performs the first operation when the terminal device monitors the wake-up signal on the time domain unit that overlaps with the time window. The following is predefined: the priority of the second operation is higher than the priority of the first operation, the priority of the scheme B is higher than the priority of the scheme A, the terminal device performs the second operation when the terminal device monitors the wake-up signal on the time domain unit that overlaps with the time window, and the terminal device performs the second operation when the terminal device monitors the wake-up signal on the time domain unit that overlaps with the time window. Based on this, the following two scenarios are included.

[0315] In a possible scenario, in step S1430, if the terminal device monitors the wake-up signal on the time domain unit that overlaps with the time window in the N time domain units, the first operation is performed, including: if the terminal device monitors the wake-up signal on the time domain unit that overlaps with the time window in the N time domain units, and the priority of the first operation is higher than the priority of the second operation, the first operation is performed.

[0316] In another possible scenario, the method 1400 further includes: if the terminal device monitors the wake-up signal on the time domain unit that overlaps with the time window in the N time domain units, and the priority of the second operation is higher than the priority of the first operation, the second operation is performed. In this scenario, the method 1400 includes steps S1410 and S1420, and S1420 can be replaced with: the terminal device performs the second operation when the terminal device monitors the wake-up signal on the N time domain units.

[0317] The above several implementation manners are examples, and embodiments of the present application are not limited thereto. For example, other operations can also be performed when the wake-up signal is monitored on the time domain unit overlapping with the time window.

[0318] The related schemes of the first operation and the second operation are introduced below.

[0319] The first operation and the second operation are different. For example, the first operation and the second operation trigger different timers.

[0320] In a possible implementation, the first operation triggers starting of the first timer, in other words, the first operation triggers starting of the first timer; and the second operation triggers starting of the second timer, in other words, the second operation triggers starting of the second timer. Specifically, if the terminal device monitors the wake-up signal on the time domain unit overlapping with the time window in the N time domain units, starting of the first timer is triggered; and if the terminal device monitors the wake-up signal on the time domain unit not overlapping with the time window in the N time domain units, starting of the second timer is triggered.

[0321] The first timer is, for example, the timer in the scheme A described above, and the second timer is, for example, the timer in the scheme B described above.

[0322] As an example, the first timer is drx-onDurationTimer.

[0323] As an example, the second timer is at least one of the following: a timer triggered to start by the wake-up signal; there is a time difference between the time when the second timer starts and the time when the terminal device receives the wake-up signal, and the time difference can be configured by the network device, or determined according to the terminal capability report, or predefined; and the terminal device monitors PDCCH in the time when the second timer runs. The terminal device and the network device can be aligned at the time when the second timer starts after the wake-up signal, and thus the terminal device and the network device can be aligned at the time domain resource position of the PDCCH (i.e., the network device can send the PDCCH) monitored by the terminal device after the wake-up signal.

[0324] Referring to FIG. 16, as an example, FIG. 16 is a schematic diagram of a communication method 1600 provided by an embodiment of the present application. The method 1600 shown in FIG. 16 can include the following steps.

[0325] S1610, the terminal device receives configuration information #3, and the configuration information #3 indicates N1 first time domain units, the N1 first time domain units are associated with the time duration onDuration, and N1 is an integer greater than 1 or equal to 1.

[0326] The N1 first time domain units can also be replaced by a time domain resource (for distinction, referred to as time domain resource #A).

[0327] In the embodiments of the application, the first time domain unit and the second time domain unit both represent a time domain unit for monitoring the wake-up signal. Specifically, the time domain unit for monitoring the wake-up signal in scheme A can be referred to as the first time domain unit, and the time domain unit for monitoring the wake-up signal in scheme B can be referred to as the second time domain unit. Considering that the terminal device may perform different operations after monitoring the wake-up signal on different time domain units (i.e., different time domain monitoring positions), the first time domain unit and the second time domain unit are used here for the convenience of description and differentiation. The following is described from the perspective of the first time domain unit and the second time domain unit respectively.

[0328] The N1 first time domain units are associated with the onDuration, in other words, the N1 first time domain units can be determined based on the onDuration, for example, the N1 first time domain units are located at positions before the start position of the time period indicated by the onDuration. In one possible implementation, the N1 first time domain units are determined based on a time window associated with the onDuration. Specifically, the time window can be determined based on the onDuration, and then the N1 first time domain units are determined in the time window, for example, the N1 first time domain units include multiple time domain units in the time window with the same interval. For the description of the time window, reference can be made to the related description in the method 1400, which will not be described here.

[0329] Optionally, the configuration information #3 includes an offset between the N1 first time domain units and the onDuration. For example, the configuration information #3 includes an offset between the end position of the N1 first time domain units and the start position of the onDuration. For another example, the configuration information #3 includes an offset between the start position of the N1 first time domain units and the start position of the onDuration. In this way, the terminal device determines the positions of the N1 first time domain units based on the offset and the time period indicated by the onDuration.

[0330] As an example, the configuration information #3 is received by the terminal device through the main circuit, i.e., the terminal device receives the configuration information #3 through the main circuit in S1610. As an example, the configuration information #3 is carried in at least one of the following: MAC signaling (e.g., MAC CE), DCI, RRC signaling, etc.

[0331] In S1620, the terminal device receives configuration information #4, and the configuration information #4 indicates N2 second time domain units, the N2 second time domain units are periodic, and N2 is an integer greater than 1 or equal to 1.

[0332] The N2 second time domain units can also be replaced by time domain resources (referred to as time domain resources #B for distinction). The N2 second time domain units are periodic, in other words, the interval between each adjacent two of the N2 second time domain units is the same.

[0333] As an example, the configuration information #4 is received by the terminal device through the main circuit, that is, the terminal device receives the configuration information #4 through the main circuit in S1620. As an example, the configuration information #4 is carried in at least one of the following: MAC signaling (for example, MAC CE), DCI, RRC signaling, etc.

[0334] Optionally, the configuration information #4 includes a period of the N2 second time domain units and / or an offset of the N2 second time domain units. The period of the N2 second time domain units, or the monitoring period of the wake-up signal, refers to how long the terminal device (or terminal device group) monitors the wake-up signal every time. The offset of the N2 second time domain units, or the monitoring offset value or the monitoring offset value of the wake-up signal, refers to the offset relative to the reference position in each monitoring period of the wake-up signal. The reference position can be the starting position, or it can also be a specific moment of the system time (for example, OFDM symbol #0 of slot #0 of subframe #0 in frame #0), which is not limited. The network device can configure different offsets for different terminal devices (or terminal device groups) to stagger the time domain monitoring positions of different terminal devices (or terminal device groups), thereby avoiding congestion or conflict of the wake-up signals of too many terminal devices. It can be understood that the period of the N2 second time domain units is independent of the period in the DRX configuration, in other words, the period of the N2 second time domain units is independently configured from the period in the DRX configuration. The offset of the N2 second time domain units is independent of the offset in the DRX configuration, in other words, the offset of the N2 second time domain units is independently configured from the offset in the DRX configuration.

[0335] In S1630, if the terminal device monitors the wake-up signal in the first time domain unit, a first operation is performed; if the terminal device monitors the wake-up signal in the second time domain unit, a second operation is performed.

[0336] Regarding the first operation and the second operation, reference can be made to the related description in method 1400, which will not be repeated here.

[0337] Based on method 1600, scheme A and scheme B can be independently configured, that is, the time domain unit (i.e., the first time domain unit) for monitoring the wake-up signal in scheme A and the time domain unit (i.e., the second time domain unit) for monitoring the wake-up signal in scheme B can be independently configured. Then the following two situations can occur.

[0338] One possible situation is that the first time domain unit and the second time domain unit do not overlap.

[0339] Referring to FIG. 17, as an example, FIG. 17 is another schematic diagram of a time domain unit for monitoring a wake-up signal according to an embodiment of the present application. As shown in FIG. 17, a first time domain unit is determined based on the onDuration, and an offset between an end position of the first time domain unit and the onDuration is greater than or equal to 0. A second time domain unit occurs periodically, and an interval between every two adjacent time domain units in the second time domain unit is T6.

[0340] As shown in (a) of FIG. 17, the first time domain unit and the second time domain unit do not overlap, and in this case, if the terminal device monitors the wake-up signal in the first time domain unit, a first operation is performed, and if the terminal device monitors the wake-up signal in the second time domain unit, a second operation is performed.

[0341] Another possible case is that the first time domain unit and the second time domain unit overlap.

[0342] As shown in (b) of FIG. 17, the first time domain unit and the second time domain unit overlap, and for ease of description, the overlapping position is referred to as a third time domain unit. In this case, when the terminal device monitors the wake-up signal in the third time domain unit, the terminal device can perform the first operation or the second operation. The following describes several possible implementation manners of determining which operation to perform.

[0343] One possible implementation manner is that the terminal device determines to perform the first operation or the second operation based on information carried in the wake-up signal.

[0344] Another possible implementation manner is that the terminal device determines to perform the first operation or the second operation based on priority information.

[0345] Another possible implementation manner is that the first operation or the second operation is predefined.

[0346] The above implementation manners can refer to the related description in the method 1400, and will not be described here.

[0347] It can be understood that in the embodiments of the present application, “monitoring” can be used alternatively with “receiving”, “detecting” or “reading”. For example, “monitoring a wake-up signal” can be replaced by “receiving a wake-up signal”, “detecting a wake-up signal” or “reading a wake-up signal”.

[0348] It can also be understood that in the embodiments of the present application, if the terminal device knows that it is woken up, such as knowing that it is woken up based on the wake-up signal, the terminal device can immediately access the network device, or the terminal device can also access the network device after a period of time, which is not limited.

[0349] It can also be understood that in some of the above embodiments, the main circuit and the wake-up circuit are mainly exemplarily described, and the application is not limited thereto. For example, the wake-up circuit can also be replaced by any of the following: the first circuit, the first module, the wake-up link, in the first state, in the first mode. For example, the terminal device uses the wake-up circuit to monitor the wake-up signal, which can also be replaced by any of the following: the terminal device uses the first circuit to monitor the wake-up signal, the terminal device monitors the wake-up signal through the first module, the terminal device monitors the wake-up signal on the wake-up link, the terminal device monitors the wake-up signal in the first mode or the first state. The main circuit can also be replaced by any of the following: the second circuit, the second module, the wake-up link, in the second state, in the second mode. For example, the terminal device uses the main circuit to measure and / or report channel information, which can also be replaced by any of the following: the terminal device uses the second circuit to measure and / or report channel information, the terminal device measures and / or reports channel information through the second module, the terminal device measures and / or reports channel information on the wake-up link, the terminal device measures and / or reports channel information in the second mode or the second state.

[0350] It can also be understood that in the embodiments of the application, the interaction between the terminal device and the network device is mainly exemplarily described, and the application is not limited thereto. The terminal device can be replaced by a receiving end device, and the receiving end device can be a terminal device or a network device. The network device can be replaced by a sending end device, and the sending end device can be a terminal device or a network device. For example, the "terminal device" can be replaced by the "first terminal device", and the "network device" can be replaced by the "second terminal device".
