Description

Technical Field

[0001] This application relates to the field of wireless communication, and more particularly, to a method for signal transmission and a communication device. Background Art

[0002] A terminal device can receive a wake-up signal through a separate low-power small circuit, such as a wake up radio (WUR), and the main circuit can be in a sleep state. When the terminal device detects a wake-up signal through the WUR, the terminal device triggers the wake-up of the main circuit. After the main circuit is awakened, the terminal device can receive other signals, such as reference signals, through the main circuit. Summary of the Invention

[0003] This application provides a method for signal transmission and a communication device, which can enable a terminal device to receive a reference signal and not miss detecting a wake-up signal after introducing the wake-up signal.

[0004] In a first aspect, a method for signal transmission is provided, and the method can be executed by a device. The device can be a device (such as a terminal device), or it can also be a component of a device (such as a chip or a chip system or a circuit), and this application does not make any limitation thereto.

[0005] The method may include: determining a time-domain resource of a reference signal and a time-domain resource of a wake-up signal; receiving the reference signal within some or all of the time-domain resources in the time-domain resource of the reference signal; monitoring the wake-up signal within the time-domain resource of the wake-up signal.

[0006] Based on the above technical solution, taking a terminal device as an example, considering that the terminal device may receive a wake-up signal through a wake-up circuit or may receive other signals (such as reference signals) through the main circuit, therefore, the terminal device can determine the time-domain resource of the reference signal and the time-domain resource of the wake-up signal, so that it can receive the reference signal within some or all of the time-domain resources in the determined time-domain resource of the reference signal, and based on the determined time-domain resource of the wake-up signal, monitor the wake-up signal within the time-domain resource of the wake-up signal. Based on this, the terminal device can receive the reference signal and monitor the wake-up signal within the determined time-domain resources. In addition, the time-domain resource of the reference signal and the time-domain resource of the wake-up signal can be made different, so that the two signals (i.e., the reference signal and the wake-up signal) can be transmitted in different time-domain resources, avoiding missing detection of one of the signals (such as missing detection of the wake-up signal) when the reference signal and the wake-up signal are transmitted at the same position. Compared with the terminal device receiving the reference signal or the wake-up signal at any position, the above technical solution can avoid the terminal device missing detection of the wake-up signal.

[0007] In combination with the first aspect, in some implementations of the first aspect, the reference signal is a signal for measurement, and the wake-up signal is used to wake up at least one terminal device.

[0008] In combination with the first aspect, in some implementations of the first aspect, the method further includes: sending at least one piece of capability information, each piece of capability information in the at least one piece of capability information indicating whether it is possible to simultaneously receive a first type of signal and a second type of signal, where the first type of signal includes the wake-up signal, the second type of signal includes the reference signal, the first type of signal uses on-off keying (OOK) modulation, and the second type of signal uses non-OOK modulation.

[0009] Based on the above technical solution, the terminal device can report its own capability information, such as whether it can simultaneously receive a first type of signal and a second type of signal, or in other words, whether it can simultaneously receive a signal modulated by OOK and a signal not modulated by OOK. This facilitates the network side (such as a network device) to perform corresponding processing according to the capability information reported by the terminal device. For example, if the terminal device cannot simultaneously receive a first type of signal and a second type of signal, the network side can configure the time-domain resources of the corresponding reference signal and the time-domain resources of the wake-up signal for the terminal device, so that the time-domain resources of the wake-up signal and the reference signal are staggered to avoid missed detection of signals.

[0010] In combination with the first aspect, in some implementations of the first aspect, one piece of capability information in the at least one piece of capability information is for one frequency band or a combination of frequency bands.

[0011] Based on the above technical solution, the capability information can be for one frequency band (per band) or for a combination of frequency bands (per band combination). In this way, the terminal device can report the capability information of each frequency band or frequency band combination for different frequency bands or frequency band combinations.

[0012] In combination with the first aspect, in some implementations of the first aspect, the method further includes: receiving the first type of signal through a wake-up circuit and receiving the second type of signal through a main circuit.

[0013] Based on the above technical solution, the first type of signal and the second type of signal can be signals received by the terminal device through different circuits. In this way, the capability information reported by the terminal device can also be whether the terminal device can simultaneously receive signals through the main circuit and the wake-up circuit.

[0014] In combination with the first aspect, in some implementations of the first aspect, the method further includes: not monitoring the wake-up signal within the time-domain resources of the reference signal.

[0015] Based on the above technical solution, the terminal device may not monitor the wake-up signal within the time domain resources of the reference signal. For example, the network device may configure the time domain resources of the reference signal for the terminal device. In this way, the network device sends the reference signal within the time domain resources of the reference signal and does not send the wake-up signal. The terminal device may not monitor the wake-up signal within the time domain resources of the reference signal, which can align the time domain resource positions for measurement and the time domain resource positions for monitoring the wake-up signal between the terminal device and the network device, avoid the situation of missed detection of the wake-up signal, and also reduce the power consumption caused by the terminal device monitoring the wake-up signal.

[0016] Combined with the first aspect, in some implementation manners of the first aspect, determining the time domain resources of the reference signal includes: receiving configuration information, where the configuration information includes information about the time domain resources of the reference signal.

[0017] Combined with the first aspect, in some implementation manners of the first aspect, the time domain resources of the reference signal include at least one time window; alternatively, the time domain resources of the reference signal include a first time domain resource in the at least one time window, where the first time domain resource is the time domain resource in which the reference signal is transmitted.

[0018] Based on the above technical solution, the terminal device may receive the reference signal within relatively concentrated time domain resources (i.e., within at least one time window). In this way, if the terminal device receives the reference signal through the main circuit and the wake-up signal through the wake-up circuit, the number of times of switching between the main circuit / wake-up circuit (or sleep / wake-up) of the terminal device can be reduced, thereby reducing the power consumption of the terminal device.

[0019] Combined with the first aspect, in some implementation manners of the first aspect, the time domain resources of the reference signal include at least one time window, and the method further includes: not monitoring the wake-up signal within the at least one time window.

[0020] Combined with the first aspect, in some implementation manners of the first aspect, the time domain resources of the reference signal include a first time domain resource in the at least one time window, and the method further includes: not monitoring the wake-up signal within the first time domain resource, and / or monitoring the wake-up signal within the time domain resources in the at least one time window other than the first time domain resource.

[0021] Combined with the first aspect, in some implementation manners of the first aspect, the method further includes: receiving first indication information, where the first indication information indicates the at least one time window.

[0023] Optionally, the offset between the at least one time window and the discontinuous reception (DRX) in the connected state includes any one of the following: the offset between the start position of the at least one time window and the start position of the DRX's OnDuration; the offset between the start position of the at least one time window and the end position of the DRX's OnDuration; the offset between the start position of the at least one time window and the middle position of the DRX's OnDuration; the offset between the start position of any one time window among the at least one time window and the start position of the DRX's OnDuration; the offset between the start position of any one time window among the at least one time window and the end position of the DRX's OnDuration; or, the offset between the start position of any one time window among the at least one time window and the middle position of the DRX's OnDuration.

[0024] In combination with the first aspect, in some implementations of the first aspect, the at least one time window is predefined.

[0025] Optionally, the offset between the at least one time window and the DRX is predefined. As an example, the offset includes any one of the following: the offset between the start position of the at least one time window and the start position of the DRX's OnDuration; the offset between the start position of the at least one time window and the end position of the DRX's OnDuration; the offset between the start position of the at least one time window and the middle position of the DRX's OnDuration; the offset between the start position of any one time window among the at least one time window and the start position of the DRX's OnDuration; the offset between the start position of any one time window among the at least one time window and the end position of the DRX's OnDuration; or, the offset between the start position of any one time window among the at least one time window and the middle position of the DRX's OnDuration.

[0027] Based on the above technical solution, the time-domain resources for the terminal device to receive the reference signal and the wake-up signal are different, so that the terminal device can either receive the reference signal or receive the wake-up signal at the same time, avoiding transmitting the wake-up signal during the transmission of the reference signal, and thus missing the detection of the wake-up signal or the reference signal.

[0029] In combination with the first aspect, in some implementations of the first aspect, the method further includes: sending second indication information, where the second indication information indicates the time-domain resources for the terminal device to expect to transmit the reference signal.

[0030] Based on the above technical solution, the terminal device can report the time-domain resources for the terminal device to expect to transmit the reference signal to the network device, so that the network device can determine the time-domain resources of the reference signal (such as the time window above) with reference to the time-domain resources expected by the terminal device in the second indication information, which can make the configured time-domain resources of the reference signal more in line with the needs of the terminal device.

The embodiments of the present application do not limit the scenarios where the network device and the terminal device are located.

[0110] First, in combination with Figure 1 A communication system applicable to the embodiments of the present application will be briefly introduced as follows.

[0111] Referring to Figure 1 , as an example, Figure 1 is a schematic diagram of a wireless communication system applicable to the embodiments of the present application. As Figure 1 shown, the wireless communication system includes a radio access network 100. The radio access network 100 may be a next-generation (e.g., 6G or higher) radio access network or a traditional (e.g., 5G, 4G, 3G, or 2G) radio access network. One or more terminal devices (120a - 120j, collectively referred to as 120) may be interconnected or connected to one or more network devices (110a, 110b, collectively referred to as 110) in the radio access network 100. The network elements in the wireless communication system are connected via interfaces (e.g., NG, Xn) or the air interface.

[0112] Among them, when the network device communicates with the terminal device, the network device may manage one or more cells, and at least one terminal device may be included in one cell. A cell can be understood as an area within the wireless signal coverage range of the network device.

[0113] Figure 1 This is just a schematic diagram. The wireless communication system may further include other devices, such as a core network device, a wireless relay device, and / or a wireless backhaul device, etc., which are not drawn in Figure 1 .

[0114] To facilitate the understanding of the embodiments of the present application, the terms involved in the present application will be briefly described.

[0115] 1. Wake-up circuit: Also known as a wake-up receiver / radio (WUR), a low-power wake-up receiver (LP-WUR), or a wake-up module, it can be understood as a separate low-power small circuit, such as the circuit used by the terminal device in the idle state. This low-power small circuit can be implemented using a simple and separate small circuit or chip with low power consumption. It can be understood that the wake-up circuit is only named for distinction, and its specific naming 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 the first circuit (or the first module). It will be uniformly described as the wake-up circuit hereinafter.

[0116] The signal received by the terminal device through the wake-up circuit can be referred to as being transmitted on the wake-up link. Herein, the wake-up link represents a connection relationship between the terminal device and the network device, which is a logical concept rather than a physical entity. It can be understood that the wake-up link is only a naming for distinction, and its specific naming does not limit the protection scope of this application. For example, without loss of generality, the wake-up link can also be described as the first link. Hereinafter, it is uniformly described as the wake-up link.

[0117] For distinction, as an example, the signal received by the terminal device through the wake-up circuit can be called the first type of signal. It can be understood that the first type of signal is only a naming for distinction, and its specific naming does not limit the protection scope of this application. For example, without loss of generality, the first type of signal can also be called a signal. Hereinafter, it is uniformly described as the first type of signal.

[0118] As an example, the first type of signal includes a wake-up signal (WUS) and / or a synchronization signal.

[0119] Among them, the wake-up signal can be used to wake up at least one terminal device. Waking up the terminal device means waking up the main circuit of the terminal device. As an example, the wake-up signal is used to indicate paging-related information, and the paging-related information can include, for example: whether a terminal device or a group of terminal devices is being paged. The wake-up signal can also be called a low-power wake-up signal (LP-WUS), and its specific naming does not limit the protection scope of this application.

[0120] Among them, the synchronization signal can be used to implement the synchronization function and can also be used to implement some measurement functions performed through the wake-up circuit, such as radio resource management (RRM) measurement. The synchronization signal can also be called a low-power synchronization signal (LP-SS).

[0121] 2. Main circuit: Also known as the main receiver (MR) or the main module, it can be understood as the circuit used by the terminal device when normally transmitting data, or the circuit used by the terminal device when transmitting data in the connected state. When the terminal device transmits data through the main circuit, the power consumption is relatively large. It can be understood that the main circuit is only a naming for distinction, and its specific naming does not limit the protection scope of this application. For example, without loss of generality, the main circuit can also be described as the second circuit (or the second module). Hereinafter, it is uniformly described as the main circuit.

[0122] The signal received by the terminal device through the main circuit can be referred to as being transmitted on the main link. Herein, the main link represents a connection relationship between the terminal device and the network device, which is a logical concept rather than a physical entity. It can be understood that the main link is only a name for distinction, and its specific name does not limit the protection scope of this application. For example, without loss of generality, the main link can also be described as the second link. Hereinafter, it is uniformly described as the main link.

[0123] Hereinafter, for distinction, the signal received by the terminal device through the main circuit is denoted as the second type of signal.

[0124] See Figure 2 , as an example, Figure 2 is a schematic diagram of the main circuit and the wake-up circuit.

[0125] As Figure 2 shown, the terminal device can receive (or detect, or monitor) the first type of signal (such as a wake-up signal) through the wake-up circuit, and the terminal device can receive the second type of signal through the main circuit. Assume that the terminal device receives a wake-up signal through the wake-up circuit. If the terminal device does not detect the wake-up signal, it 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, it triggers the wake-up of the main circuit, that is, makes the main circuit be / switched to an open state (or called a working state, or called an active state). After the main circuit is turned on, the terminal device can transmit the second type of signal through the main circuit.

[0126] 3. Relationship between the wake-up circuit and the main circuit: Considering size and cost, the wake-up circuit and the main circuit can share the same antenna (or called a physical antenna).

[0127] The following combines Figure 3 to introduce two possible ways of connecting the wake-up circuit and the main circuit to the antenna.

[0128] Method 1: The antenna is respectively connected to the wake-up circuit and the main circuit. At this time, the wake-up circuit and the main circuit may receive signals simultaneously.

[0129] See Figure 3 , as an example, Figure 3 is a schematic diagram of the connection between the wake-up circuit and the main circuit and the antenna. As Figure 3 shown in (a) of Figure 3 (denoted as LR in Figure 3 ) and the main circuit (denoted as MR in Figure 3 ). At this time, the signal power received by the antenna will be split, so the signal powers of the wake-up circuit and the main circuit will attenuate, such as attenuating 3 dB.

[0130] Mode 2: The antenna is connected to the wake-up circuit or the main circuit through a switch. In this case, the wake-up circuit and the main circuit may not receive signals simultaneously, or they may receive signals simultaneously. As shown in Figure 3 , (b) or (c), the antenna can be connected to the wake-up circuit or the main circuit through a switch. In this case, due to the introduction of the switch, the signal power received by the antenna will also attenuate, but the attenuation is smaller than that of the splitter. In Figure 3 , (b), since the switch is either connected to the wake-up circuit or the main circuit, the wake-up circuit and the main circuit will not receive signals simultaneously. In addition, considering that the wake-up circuit and the main circuit may be related to the operating frequency point, when using Mode 2, if the wake-up circuit and the main circuit operate at different frequency points, the wake-up circuit and the main circuit may receive signals simultaneously. As shown in Figure 3 , (c), if the wake-up circuit operates in band 1, the main circuit operates in band 2, and the terminal device receives signals in band 1 and band 2 using different antennas, then even if connected by a switch, the wake-up circuit and the main circuit may still receive signals simultaneously.

[0131] As can be seen from the above, depending on the hardware structure of the terminal device, the wake-up circuit and the main circuit may receive signals simultaneously or may not receive signals simultaneously.

[0132] 4. Reference signal (RS) and reference signal resources: The reference signal can be used for channel measurement, beam measurement, channel estimation, etc. The reference signal resources can be used to configure the transmission attributes of the reference signal, such as time-frequency resource location, port mapping relationship, power factor, and scrambling code, etc. The transmitting device can send the reference signal based on the reference signal resources, and the receiving device can receive the reference signal based on the reference signal resources.

[0133] 5. Time-domain resources: Data or information can be carried by resources. In the time domain, resources can be called time-domain resources. Time-domain resources can include one or more time-domain units (or, can also be called time units). A time unit can be a symbol, or an orthogonal frequency division multiplexing (OFDM) symbol, or a mini-slot, or a slot, or a partial slot, or a subframe, or a radio frame, etc.

[0134] 6. Measurement: The terminal device can perform various measurements in the connected state. Specifically, it can perform measurements based on the reference signal. Here are a few simple introductions.

[0135] 1) Radio Link Monitoring (RLM) and Beam Failure Detection (BFD)

[0136] The procedures for the terminal device to perform RLM and BFD are similar. Taking RLM as an example, the following are the possible steps.

[0137] Step 1, the terminal device receives a reference signal. As an example, the reference signal can be a Synchronization Signal Block (SSB) or a Channel State Information Reference Signal (CSI-RS).

[0138] The resources for RLM can be configured specifically for a particular UE (UE-specific) through the radioLinkMonitoringConfig in the Bandwidth Part - Downlink Dedicated (BWP-DownlinkDedicated). In addition to the resources for RLM, the resources configured by the network side through radioLinkMonitoringConfig also include other resources, such as resources for BFD. For example, there are N LR-RLM reference signal resources in radioLinkMonitoringConfig. As an example, among them, at most N RLM are for RLM and at most 2 are for BFD. The resources used for RLM and BFD can be the same or different. The values of N LR-RLM and N RLM are related to the maximum number of reference signals (such as SSB).

[0139] In addition, if the terminal device is not configured with a Radio Link Monitoring Reference Signal (RadioLinkMonitoringRS), but the Transmission Configuration Indication (TCI) state of the Physical Downlink Control Channel (PDCCH) contains one or more CSI-RS, then the terminal device can use these CSI-RS for RLM. Specifically, which CSI-RS to use for RLM can be all or part of them in a specific order as agreed by the protocol, and this is not limited.

[0140] Step 2, the terminal device calculates the quality (or radio link quality) based on each reference signal.

[0141] As an example, the metric (or measurement quantity) includes at least one of the following: reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), or signal-noise ratio (SNR).

[0142] When the terminal device calculates the quality, it can be calculated within a certain time period (such as the evaluation period). To achieve a better filtering effect, multiple samples are usually used (the specific number of samples depends on the implementation of the terminal device). If the reference signal is SSB, this period includes T Evaluate_out_SSB and T Evaluate_in_SSB ; if the reference signal is CSI-RS, this period includes T Evaluate_out_CSI-RS and T Evaluate_in_CSI-RS .

[0143] Step 3, the terminal device compares the quality calculated based on each reference signal with the corresponding threshold (such as Q out and Q in ). For the thresholds corresponding to different reference signals, they can have their own values. For example, for a terminal device, there may be four parameters Q out_SSB , Q in_SSB , Q out_CSI-RS , Q in_CSI-RS . Q out_SSB is used to compare with the quality calculated from the reference signal within the T Evaluate_out_SSB time period, Q in_SSB is used to compare with the quality calculated from the reference signal within the T Evaluate_in_SSB time period, Q out_CSI-RS is used to compare with the quality calculated from the reference signal within the T Evaluate_out_CSI-RS time period, and Q in_CSI-RS is used to compare with the quality calculated from the reference signal within the T Evaluate_in_CSI-RS time period.

[0144] Step 4. According to the comparison result, the physical layer in the terminal device indicates out of sync (OOS) or in sync (IS) to the radio resource control (RRC) layer. Specifically, if the quality of all reference signals is lower than the threshold (Q out ), then OOS is indicated; if the quality of at least one reference signal is higher than Q in , then IS is indicated; in other cases, the indication may not be sent.

[0145] The above steps are for illustrative purposes and are not limited in the embodiments of this application.

[0146] 2) Channel state information (CSI) measurement

[0147] As an example, the CSI measurement includes the following steps:

[0148] Step 1. The terminal device receives a reference signal.

[0149] Step 2. The terminal device measures the reference signal. For different scenarios (such as intra-frequency or inter-frequency, different frequency ranges, different discontinuous reception (DRX) cycle lengths), the requirements for the measurement period are different, and the protocol does not specify at what position within a period to perform the measurement.

[0150] Step 3. The terminal device reports the measurement result. Generally, the terminal device can report a CSI report through the physical uplink control channel (PUCCH).

[0151] 3) RRM measurement

[0152] As an example, the RRM measurement (or also referred to as cell measurement) includes serving cell measurement and neighbor cell measurement. As an example, the neighbor cell measurement includes at least one of the following: intra-frequency measurement, inter-frequency measurement, and inter-radio access technology (inter-RAT) measurement.

[0153] Similarly, the RRM measurement includes the following steps: The terminal device receives a reference signal; the terminal device measures the reference signal; the terminal device reports the measurement result.

[0154] The above briefly introduces some measurements, mainly some measurements when the terminal device is in the connected state. For different measurements, the measurement requirements may be different. For example, the measurement period may be different.

[0155] In the connected state, the services of the terminal device arrive more frequently than in the idle state. Therefore, the main circuit of the terminal device will be turned on more frequently to send and receive data. To reduce the complexity of protocol design, a possible implementation is to perform some measurement behaviors in the connected state through the main circuit, such as including but not limited to: RLM, BFD, CSI measurement, or RRM measurement, etc.

[0156] However, as mentioned above, the wake-up circuit and the main circuit of the terminal device may not be able to receive signals simultaneously. In this way, the terminal device cannot simultaneously use the wake-up circuit to receive the wake-up signal and use the main circuit to perform measurements (or use the main circuit to receive the reference signal for measurement). Then there will be a situation: The network side sends a wake-up signal at the time domain position where the terminal device performs measurements, so the terminal device may miss detecting this wake-up signal.

[0157] In view of this, the present application proposes a solution. By configuring or defining the time domain position for measurement, that is, the terminal device performs measurements at this time domain position, and the network device does not send a wake-up signal at this time domain position. In this way, the terminal device and the network device can align the time domain position where the terminal device uses the main circuit to perform measurements, and avoid missing the detection of the wake-up signal.

[0158] Before introducing the solution of the present application, the following points are explained.

[0159] (1) In the present application, "indication" may include direct indication, indirect indication, display indication, implicit indication. When it is described that a certain indication information is used to indicate A, it can be understood that this indication information carries A, directly indicates A, or indirectly indicates A.

[0160] In this application, the information indicated by the indication information is referred to as the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated. For example, but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. It is also possible to indirectly indicate the information to be indicated by indicating other information, where there is an association relationship between the other information and the information to be indicated. It is also possible to only indicate a part of the information to be indicated, while the other parts of the information to be indicated are known or pre-agreed. For example, it is also possible to use the arrangement order of each piece of information pre-agreed (such as protocol regulations) to indicate specific information, thereby reducing the indication overhead to a certain extent. In addition, the information to be indicated can be sent as a whole, or divided into multiple sub-information and sent separately, and the sending periods and / or sending times of these sub-information can be the same or different.

[0161] (2) In this application, the expression " / " is used to indicate that the objects associated before and after are in an "or" relationship; for example, A / B can mean: A or B. The expression "and / or" is used to indicate that the objects associated before and after can be either in an "and" association relationship or in an "or" association relationship; for example, A and / or B can represent the following situations: A exists alone, B exists alone, A and B exist simultaneously, where A and B can be single or multiple. "At least one of the following" or its similar expressions are used to indicate any combination of the items listed; for example, at least one of A, B, and (or) C can represent the following situations: A exists alone, B exists alone, C exists alone, A and B exist simultaneously, B and C exist simultaneously, A and C exist simultaneously, A, B, and C exist simultaneously, where A, B, and C can be single or multiple.

[0162] (3) In this application, "send" and "receive" represent the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information is XX, which can include directly sending through the air interface, and also include indirectly sending through the air interface by other units or modules. "Receive information from YY" can be understood as the source of the information is YY, which can include directly receiving from YY through the air interface, and can also include indirectly receiving from YY through the air interface from other units or modules. "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 be carried out between devices, for example, between a network device and a terminal device, or can be carried out within a device, for example, sending or receiving between components, modules, chips, software modules, or hardware modules within a device through a bus, trace, or interface.

[0163] (4) In various embodiments of the present application, if there is no special indication and logical conflict, the terms and / or descriptions between different embodiments are consistent and can be mutually referred to. The technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationships.

[0164] (5) In the present application, "first" and "second" are only for convenience of description and are used to distinguish objects, and are not used to limit the scope of the embodiments of the present application. Instead of being used to describe the order or sequence of features. It should be understood that the objects described in this way can be interchanged under appropriate circumstances so as to be able to describe the solutions other than the embodiments of the present application.

[0165] The method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments provided by the present application can be applied to the scenarios shown in the above figures, which is not limited.

[0166] See Figure 4 , as an example, Figure 4 is a schematic diagram of a signal transmission method 400 provided by an embodiment of the present application. For ease of description below, an example is given with the execution subject of method 400 being a terminal device. It can be understood that the execution subject of method 400 can also be a component of the terminal device, such as a chip or a chip system or a circuit, which is not limited thereto. The steps described below as being executed by a single execution subject can also be divided into being executed by multiple execution subjects, and these execution subjects can be separated logically and / or physically. Figure 4 The method 400 shown can include the following steps.

[0167] Method 400 includes step 420 and step 430. Optionally, method 400 includes step 410.

[0168] 410, the terminal device determines the time-domain resources of the reference signal and the time-domain resources of the wake-up signal.

[0169] As an example, the reference signal is used for measurement. Specifically, the terminal device can perform measurement based on the reference signal, that is, the terminal device performs measurement through the main circuit based on the reference signal. As an example, the measurement includes at least one of the following: RLM, BFD, channel measurement (such as CSI measurement), RRM measurement (or also referred to as cell measurement), or beam measurement, etc. For the descriptions of the above various measurements, reference can be made to the relevant descriptions in the previous term explanation section. In addition, the specific manner of measurement in the embodiments of the present application is not limited.

[0170] Among them, the time-domain resources of the reference signal represent the time-domain resources where the reference signal can be received, or the time-domain resources where measurement can be performed.

[0171] Among them, determining the time-domain resources of the reference signal can also be replaced by: determining the time-domain resources for not monitoring the wake-up signal.

[0172] As an example, the wake-up signal includes being used to wake up at least one terminal device. For the wake-up signal, reference can be made to the relevant descriptions above.

[0173] Among them, determining the time-domain resources of the wake-up signal can also be replaced by: determining the time-domain resources for monitoring the wake-up signal.

[0174] As an example, the modulation method of the wake-up signal is OOK modulation; the modulation method of the reference signal is non-OOK modulation, such as the modulation method of the reference signal is orthogonal frequency division multiplexing (OFDM) modulation or discrete fourier transformation-spread-orthogonal frequency division multiplexing (DFT-s-OFDM) modulation.

[0175] Among them, the modulation method of the wake-up signal is OOK modulation, which can also be described as follows: within the time interval corresponding to the wake-up signal, there is energy at some time domain positions and no energy at some time domain positions; or the energy at some time domain positions is higher than the first threshold, and the energy at some time domain positions is lower than the second threshold, where the first threshold is greater than or equal to the second threshold; or, the wake-up signal includes X OOK symbols, and the X OOK symbols include X1 first symbols and X2 second symbols. The signal amplitude of the first symbol is greater than or equal to the first threshold, and the signal amplitude of the second symbol is less than or equal to the second threshold, where X is an integer greater than 0, and X1 and X2 are integers greater than or equal to 0, and X1 + X2 = X. Among them, the signal amplitude of the first symbol being greater than or equal to the first threshold and the signal amplitude of the second symbol being less than or equal to the second threshold can be replaced by any of the following: the signal amplitude of the first symbol is greater than the signal amplitude of the second symbol; within a preset time period, the signal amplitude of the first symbol is greater than the signal amplitude of the second symbol; the signal power of the first symbol is greater than the signal power of the second symbol; within a preset time period, the signal power of the first symbol is greater than the signal power of the second symbol; the signal power of the first symbol is greater than or equal to the first threshold, and the signal power of the second symbol is less than or equal to the second threshold; within a preset time period, the signal power of the first symbol is greater than or equal to the first threshold, and the signal power of the second symbol is less than or equal to the second threshold; the signal level value of the first symbol is greater than the signal level value of the second symbol; within a preset time period, the signal level value of the first symbol is greater than the signal level value of the second symbol; the signal level value of the first symbol is greater than or equal to the first threshold, and the signal level value of the second symbol is less than or equal to the second threshold; within a preset time period, the signal level value of the first symbol is greater than or equal to the first threshold, and the signal level value of the second symbol is less than or equal to the second threshold; or, the first symbol indicates (or corresponds to, or represents) a first bit value, and the second symbol indicates (or corresponds to, or represents) a second bit value. Among them, the first bit value and the second bit value are different. In one example, the first bit value is "1" and the second bit value is "0". In another example, the first bit value is "0" and the second bit value is "1".

[0176] 420, the terminal device receives the reference signal within some or all of the time domain resources of the reference signal in the time domain.

[0177] Among them, the terminal device can be a connected terminal device.

[0178] The time domain resources of the reference signal in step 410 are the time domain resources that the terminal device can (or is able to) use to receive the reference signal. In actual communication, the terminal device may receive the reference signal within some of the time domain resources of the reference signal; or, the terminal device may also receive the reference signal within all of the time domain resources of the reference signal.

[0179] For example, the time-domain resources of the reference signal include N time-domain units, where N is an integer greater than 1. The terminal device receives the reference signal within N1 time-domain units out of the N time-domain units, where N1 is an integer greater than or equal to 0 and less than or equal to N. It can be understood that when N1 = 0, it means that the terminal device does not receive the reference signal within the time-domain resources of the reference signal.

[0180] 430, the terminal device monitors the wake-up signal within the time-domain resources of the wake-up signal.

[0181] Optionally, the terminal device includes a first module and a second module. The terminal device monitors the wake-up signal through (or uses) the first module and receives the reference signal through (or uses) the second module. Specifically, in step 420, the terminal device receives the reference signal through the second module within some or all of the time-domain resources of the reference signal; in step 430, the terminal device monitors the wake-up signal through the first module within the time-domain resources of the wake-up signal.

[0182] As an example, the power consumption of the first module can be less than that of the second module. The first module, for example, can be Figure 2 the wake-up circuit in, or can also be the receiving module of the wake-up circuit; the second module, for example, can be Figure 2 the main circuit in, or can also be the receiving module of the main circuit. Refer to the relevant descriptions above for the main circuit and the wake-up circuit. The following takes the main circuit and the wake-up circuit as examples for illustration.

[0183] The following introduces the related solutions regarding the time-domain resources of the reference signal and the time-domain resources of the wake-up signal. As an example, the time-domain resources of the reference signal and the time-domain resources of the wake-up signal include the following three solutions.

[0184] Solution 1, the network device configures the time-domain resources of the reference signal. Within the time-domain resources of the reference signal, the terminal device does not monitor the wake-up signal. Correspondingly, the network device does not send the wake-up signal within the time-domain resources of the reference signal. Based on this, the time-domain resources of the reference signal in step 410 are the time-domain resources of the reference signal configured by the network device. The time-domain resources of the reference signal configured by the network device mean that the network device sends the reference signal within the configured time-domain resources of the reference signal. It should be noted that for the terminal device, whether to receive the reference signal within the configured time-domain resources depends on the implementation of the terminal device, such as the measurement requirements of the terminal device. For example, the terminal device may receive the reference signal within all of the time-domain resources of the reference signal; for another example, the terminal device may receive the reference signal within some of the time-domain resources of the reference signal.

[0185] With this solution, the network device can configure the time-domain resources of the reference signal for measurement for the terminal device. In this way, the network device sends the reference signal within the time-domain resources of the reference signal and does not send the wake-up signal. The terminal device can refrain from monitoring the wake-up signal within the time-domain resources of the reference signal. This can align the time-domain resource positions for measurement between the terminal device and the network device, avoid missing the detection of the wake-up signal, and reduce the power consumption caused by the terminal device monitoring the wake-up signal.

[0186] See Figure 5 , as an example, Figure 5 is a schematic diagram of Solution 1 applicable to the embodiments of the present application. As Figure 5 shown, the network device configures the time-domain resources of the reference signal available for measurement for the terminal device (i.e., the time-domain resources of the reference signal in step 410). For simplicity, this time-domain resource is referred to as time-domain resource #1. The network device does not send the wake-up signal within this time-domain resource #1. During the process of the terminal device monitoring the wake-up signal, it does not monitor the wake-up signal within this time-domain resource #1. Specifically, it can be assumed that the terminal device may perform measurements at the positions of the time-domain resource #1. Therefore, at the positions of this time-domain resource #1, the network device does not send the wake-up signal, and the terminal device does not monitor the wake-up signal. However, from Figure 5 it can be seen that, as an example, actually the terminal device receives the reference signal for measurement on some of the time-domain resources of this time-domain resource #1, such as Figure 5 the time-domain resources for actual measurement (i.e., some of the time-domain resources of the reference signal in step 420).

[0187] Figure 5 The "original time-domain resources for monitoring the wake-up signal" shown in

[0188] at least include the following two situations. Figure 5 One possible situation is that the "original time-domain resources for monitoring the wake-up signal" shown in Figure 5 are all the time-domain resources for monitoring the wake-up signal. For example, the terminal device continuously monitors the wake-up signal within the original time-domain resources for monitoring the wake-up signal shown above. Based on Solution 1, the terminal device stops monitoring the wake-up signal (or no longer monitors the wake-up signal) within the time-domain resource #1 and can continue to monitor the wake-up signal within the remaining time-domain resources.

[0189] Another possible situation is that the "original time-domain resources for monitoring the wake-up signal" shown in Figure 5 are some of the time-domain resources among all the time-domain resources for monitoring the wake-up signal. For example, the terminal device... Figure 5Perform duty cycle monitoring of the wake-up signal within the originally monitored time-domain resources of the wake-up signal shown. For another example, the network device configures multiple time-domain resources for the wake-up signal, and the multiple time-domain resources include Figure 5 the "originally monitored time-domain resources of the wake-up signal" shown in

[0190] Based on Solution 1, further optionally, method 400 further includes: The terminal device receives configuration information, and the configuration information includes information on the time-domain resources of the reference signal.

[0191] As an example, the configuration information can be carried in radio resource control (RRC) signaling.

[0192] As an example, the information on the time-domain resources of the reference signal includes at least one of the following information: the starting position of the reference signal in the time domain, the ending position of the reference signal in the time domain, the time-domain length of the reference signal (such as the number of time-domain units occupied by the reference signal), or the index of the time-domain unit occupied by the reference signal.

[0193] Solution 2, configure or define at least one time-domain resource, and the terminal device receives the reference signal within the at least one time-domain resource and does not monitor the wake-up signal. Based on this, the time-domain resources of the reference signal in step 410 are the at least one time-domain resource.

[0194] Through this solution, the terminal device can perform measurements within relatively concentrated time-domain resources, reduce the number of times of switching of the main circuit / wake-up circuit (or sleep / wake-up) of the terminal device, and thus reduce the power consumption of the terminal device.

[0195] Among them, the at least one time-domain resource can be in the form of a time window, or can also be in the form of a time-domain unit, or can also be in the form of a time-domain length, and this is not limited. Two implementation manners are exemplified below with a time window as an example.

[0196] The first possible implementation manner, the time-domain resources of the reference signal in step 410 include at least one time window. Based on this, in step 420, the terminal device receives the reference signal within some or all of the time-domain resources of the at least one time window. Further, the terminal device does not monitor the wake-up signal within the at least one time window. In addition, the network device does not send the wake-up signal within the at least one time window.

[0197] See Figure 6 As an example, Figure 6 is a schematic diagram applicable to Solution 2 of the embodiments of the present application. AsFigure 6 As shown, within the time window, the terminal device can receive reference signals, and during the process of the terminal device monitoring the wake-up signal, the wake-up signal is not monitored within this time window. In addition, from Figure 6 it can be seen that, in fact, as an example, the terminal device receives reference signals and performs measurements at two time-domain positions within the time window (i.e., Figure 6 the time-domain resources of the reference signals actually measured as shown in Figure 6 An example of a time window is shown in . It can be understood that there may be multiple time windows in practice. These multiple time windows may be discontinuous. As an example, these multiple time windows may be periodic, that is, the time interval between every two adjacent time windows among these multiple time windows is the same.

[0198] In the second possible implementation manner, the time-domain resources of the reference signals in step 410 include partial time-domain resources within at least one time window (for distinction, this partial time-domain resource is referred to as the first time-domain resource). Based on this, in step 420, the terminal device can receive reference signals within some or all of the time-domain resources of the first time-domain resource. Among them, the first time-domain resource belongs to the time-domain resources configured for the reference signals, that is, the first time-domain resource is the time-domain resource where reference signals are transmitted, that is, the network device sends reference signals within the first time-domain resource. In actual communication, the terminal device may receive reference signals on some of the time-domain resources of the first time-domain resource, or may receive signals on all of the time-domain resources of the first time-domain resource.

[0199] Furthermore, the terminal device does not monitor the wake-up signal within the first time-domain resource of the at least one time window. In other words, within the at least one time window, the terminal device monitors the wake-up signal within the time-domain resources other than the first time-domain resource. In addition, within the at least one time window, the network device does not send the wake-up signal within the first time-domain resource of the at least one time window.

[0200] Refer to Figure 7 , as an example, Figure 7 is another schematic diagram applicable to Solution 2 of the embodiments of the present application. As shown in Figure 7 , within one time window, the first time-domain resource includes three positions. During the process of the terminal device monitoring the wake-up signal, the wake-up signal is not monitored at these three positions. At other positions within this time window, the terminal device can monitor the wake-up signal. In addition, at these three positions, the terminal device can receive reference signals, and from Figure 7 it can be known that, in fact, the terminal device receives reference signals and performs measurements based on the reference signals at two of these three positions (i.e., Figure 7 the time-domain resources of the reference signals actually measured as shown in Figure 7Exemplarily shown in [scheme] is a time window. It can be understood that there may be multiple time windows in practice. In addition, Figure 7 Exemplarily shown in [scheme] is a case where the first time-domain resource includes three discontinuous time-domain resources. This is not limited thereto. In practice, the first time-domain resource may also be continuous, or the first time-domain resource may include a greater or smaller number of discontinuous time-domain resources.

[0201] Figure 6 and Figure 7 For the time-domain resources in which the terminal device originally monitors the wake-up signal involved in [scheme], reference may be made to the relevant description in Solution 1, which will not be elaborated herein.

[0202] The following introduces the relevant solutions of at least one time-domain resource (i.e., time window) mentioned in Solution 2. The following takes the time window as an example to exemplarily introduce two implementation manners.

[0203] In the first possible implementation manner, the time window is configured by the network device.

[0204] Based on this manner, optionally, method 400 further includes: The terminal device receives first indication information, and the first indication information indicates at least one time window.

[0205] Optionally, the first indication information includes at least one of the following: the start position of at least one time window, the start position of one time window in at least one time window, the end position of at least one time window, the end position of one time window in at least one time window, the length of at least one time window, the length of one time window in at least one time window, the time interval between two adjacent time windows in at least one time window, or an offset; wherein, the offset represents the offset between at least one time window and discontinuous reception (connected DRX, CDRX) in the connected state. The following briefly introduces several examples.

[0206] Example 1: The first indication information includes the start position of one time window in at least one time window.

[0207] For example, the first indication information includes the start position of the first time window in at least one time window. In this case, the terminal device can know the start positions of each time window according to the start position of the first time window and the interval between each time window. Among them, the interval between each time window can be predefined or carried in the first indication information.

[0208] Example 2: The first indication information includes the end position of one time window in at least one time window.

[0209] Example 2 is similar to Example 1 and will not be elaborated herein.

[0210] Example 3, the first indication information includes the length of one time window among at least one time window.

[0211] For example, it can be assumed (such as predefined, or indicated by the first indication information) that the lengths of each time window are the same, so that the first indication information only needs to indicate the length of one time window.

[0212] Example 4, the first indication information includes an offset.

[0213] As an example, the offset includes at least one of the following: the offset between the start position of at least one time window and the start position of the OnDuration of CDRX, the offset between the start position of at least one time window and the end position of the OnDuration of CDRX, the offset between the start position of at least one time window and the middle position of the OnDuration of CDRX, the offset between the start position of any one time window in at least one time window and the start position of the OnDuration of CDRX, the offset between the start position of any one time window in at least one time window and the end position of the OnDuration of CDRX, or, the offset between the start position of any one time window in at least one time window and the middle position of the OnDuration of CDRX.

[0214] The second possible implementation manner is that the time window is predefined.

[0215] Based on this manner, optionally, method 400 further includes: the terminal device itself determines at least one time window.

[0216] For example, it can be predefined that frames with frame_index mode X = 1 or 2 (that is, the first 2 frames in every X frames) are the positions where the terminal device can make measurements during the process of monitoring the wake-up signal, that is, at least one time window is the first 2 frames in every X frames. Wherein, X is an integer greater than 0. For example, X = 20. "1" and "2" represent the indexes of the frames, and the indexes of the frames can also be other values.

[0217] For another example, it can be predefined that within the OnDuration of CDRX is the position where the terminal device can make measurements during the process of monitoring the wake-up signal, that is, at least one time window is the OnDuration of CDRX. Or, it can be predefined that based on the start position of the OnDuration of CDRX, the time position with a length of L (such as 20 ms) is the position where the terminal device can make measurements during the process of monitoring the wake-up signal, that is, the start position of at least one time window is the start position of the OnDuration of CDRX, and the length is L. Wherein, L is a number greater than 0.

[0218] For information about the time window, reference can be made to the description in the first possible implementation manner, which will not be elaborated here.

[0219] Solution 3: The network device configures or pre - defines the time - domain resources of the wake - up signal, and the terminal device receives the reference signal within the time - domain resources other than the time - domain resources of the wake - up signal. Based on this, the time - domain resources of the reference signal in step 410 are time - domain resources different from the time - domain resources of the wake - up signal, or time - domain resources outside the time - domain resources of the wake - up signal. Specifically, if the network device wants to send a wake - up signal, it sends the wake - up signal within the time - domain resources of the wake - up signal and does not send the wake - up signal within the time - domain resources outside the time - domain resources of the wake - up signal. Correspondingly, the terminal device monitors the wake - up signal within the time - domain resources of the wake - up signal and does not monitor the wake - up signal within the remaining time - domain resources. In addition, if the network device wants to send a reference signal (or if it wants to configure the time - domain resources of the reference signal), it sends the reference signal within the time - domain resources outside the time - domain resources of the wake - up signal, or configures the time - domain resources of the reference signal within the time - domain resources outside the time - domain resources of the wake - up signal. Correspondingly, the terminal device receives the reference signal within the time - domain resources outside the time - domain resources of the wake - up signal.

[0220] Through this solution, the terminal device and the network device align the time - domain resource positions for measurement, avoiding the situation of missing the detection of the wake - up signal.

[0221] See Figure 8 , as an example, Figure 8 is a schematic diagram of Solution 3 applicable to the embodiments of the present application. As Figure 8 shown, assume that the network device configures the time - domain resources for the terminal device to monitor the wake - up signal. The terminal device monitors the wake - up signal within the time - domain resources of the wake - up signal and does not monitor the wake - up signal within the time - domain resources outside the time - domain resources of the wake - up signal. When the terminal device wants to perform measurement based on the reference signal, it receives the reference signal for measurement within the time - domain resources outside the time - domain resources of the wake - up signal.

[0222] As an example, Figure 8 the time - domain resources for monitoring the wake - up signal shown in Figure 8 can be part of all the time - domain resources for monitoring the wake - up signal. For example, the terminal device monitors the wake - up signal in a duty - cycle manner,

[0223] Based on Solution 3, determining the time-domain resources of the reference signal and the time-domain resources of the wake-up signal in step 410 can also be replaced by: determining the time-domain resources of the wake-up signal. After determining the time-domain resources of the wake-up signal, the time-domain resources of the reference signal can also be directly determined, that is, the time-domain resources of the reference signal are the time-domain resources other than the time-domain resources of the wake-up signal, or in other words, the time-domain resources of the reference signal are the time-domain resources different from the time-domain resources of the wake-up signal. In this case, the "time-domain resources of the reference signal" are the positions where the reference signal can be received, that is, the embodiments of the present application do not limit that the reference signal is sent at all positions within the "time-domain resources of the reference signal", nor do they limit that the terminal device receives the reference signal at all positions. It only means that if the network device wants to send the reference signal, it can use the time-domain resources in the "time-domain resources of the reference signal" to send the reference signal; if the terminal device wants to receive the reference signal, it can use the time-domain resources in the "time-domain resources of the reference signal" to receive the reference signal.

[0224] In Solution 3, the time-domain resources of the reference signal are the time-domain resources other than the time-domain resources of the wake-up signal, which can be predefined or can also be configured, and this is not limited. For example, the protocol can define that the terminal device makes measurements at positions other than the time-domain resources of the wake-up signal.

[0225] Optionally, the time-domain resources of the wake-up signal are discontinuous. In other words, the wake-up signal includes multiple time-domain units in the time domain, and at least two of the multiple time-domain units are discontinuous. As an example, the discontinuous time-domain resources of the wake-up signal can be combined with Solution 3. For example, taking Solution 3 as an example, as Figure 8 shown, the time-domain resources of the wake-up signal are discontinuous.

[0226] Further optionally, the intervals between every two adjacent continuous time-domain resources are the same or different. For example, the time-domain resources of the wake-up signal include M groups of time-domain units, each group of time-domain units includes at least one time-domain unit, the time-domain units in each group of time-domain units are continuous, and the intervals between adjacent two groups of time-domain units among the M groups of time-domain units are the same or different.

[0227] A possible implementation is that the time-domain resources of the wake-up signal are periodic. Based on this, the terminal device can periodically monitor the wake-up signal.

[0228] Further, optionally, method 400 further includes: the terminal device sends second indication information to the network device, and the second indication information indicates the desired time-domain resources of the terminal device, that is, the time-domain resources for transmitting the reference signal desired by the terminal device indicated by the second indication information. Based on this, the terminal device can report the desired measurement time to the network device.

[0229] Taking the above solution 2 as an example, the network device may determine at least one time window with reference to the measurement time-domain resources expected by the terminal device in the second indication information, so that the at least one configured time window can better meet the requirements of the terminal device.

[0230] The above text describes the related solutions for the time-domain resources of the wake-up signal and the reference signal. It should be noted that for the time-domain resources of other signals monitored (or received) by the wake-up circuit, the related design of the time-domain resources of the wake-up signal in method 400 can also be referred to.

[0231] For example, method 400 can also be deformed as follows: in step 410, the terminal device determines the time-domain resources of the reference signal and the time-domain resources of the first type of signal; in step 420, the terminal device receives the reference signal within some or all of the time-domain resources of the reference signal; in step 430, the terminal device monitors (or receives) the first type of signal within the time-domain resources of the first type of signal. Among them, the first type of signal includes the wake-up signal and / or the synchronization signal (such as LP-SS).

[0232] For another example, method 400 can also be deformed as follows: in step 410, the terminal device determines the time-domain resources of the second type of signal and the time-domain resources of the first type of signal; in step 420, the terminal device receives the second type of signal within some or all of the time-domain resources of the second type of signal; in step 430, the terminal device monitors (or receives) the first type of signal within the time-domain resources of the first type of signal. Among them, the first type of signal includes the wake-up signal and / or the synchronization signal (such as LP-SS), and the second type of signal includes the reference signal.

[0233] The first type of signal and the second type of signal will be described in detail below.

[0234] Optionally, the terminal device sends capability information to the network device, and this capability information indicates whether it can receive the first type of signal and the second type of signal simultaneously (or whether it can support receiving the first type of signal and the second type of signal simultaneously). The terminal device sending the capability information to the network device can be used in combination with method 400 or independently, and this is not limited. As an example, when used in combination, the indication information may indicate that the terminal device cannot receive the first type of signal and the second type of signal simultaneously. In this way, in the case where the first type of signal and the second type of signal cannot be received simultaneously, the terminal device can receive the reference signal and monitor the wake-up signal based on the method described in method 400.

[0235] Optionally, the terminal device includes a first module and a second module. The indication information indicates whether the first type of signal and the second type of signal can be received simultaneously. Alternatively, the indication information indicates whether the first module (such as a wake-up circuit) and the second module (such as a main circuit) can receive signals simultaneously. Regarding the first module and the second module, refer to the previous description and details are not provided here. Hereinafter, the wake-up circuit and the main circuit are taken as examples for illustration.

[0236] Optionally, the first type of signal uses OOK modulation, and the second type of signal uses non-OOK modulation. For example, the modulation method of the second type of signal is OFDM or DFT-s-OFDM.

[0237] Optionally, the first type of signal includes a wake-up signal and / or a synchronization signal (such as LP-SS).

[0238] Optionally, the second type of signal is a signal different from the wake-up signal and the synchronization signal. The second type of signal can represent various downlink signals in the NR system. As an example, the first type of signal includes any one or more of the following: SSB, PDCCH, physical downlink shared channel (PDSCH), CSI-RS, phase tracking reference signal (PTRS), positioning reference signal (PRS), demodulation reference signal (DMRS).

[0239] Optionally, the capability information is per band, or the capability information is associated with a band; or, the capability information is per band combination, or the capability information is associated with a band combination. Based on this, different bands or band combinations can have their own capability information, and when reporting the capability information, it can be reported for different bands or band combinations. Among them, the band combination can also be replaced with other descriptions, such as a band group, and its naming does not limit the protection scope of the embodiments of the present application. The following describes in combination with two cases.

[0240] The first possible case is that the capability information is per band combination, or the capability information is associated with a band combination.

[0241] As an example, the capability information and the band combination can exist in the form of a table, a function, text, or a string, such as storage or transmission. The following Table 1 is an example of presenting the capability information and the band combination in tabular form.

[0242] Table 1

[0243] band combination Capability information band#1, band#2 Can receive the first type of signal and the second type of signal simultaneously band#3, band#4 Cannot receive the first type of signal and the second type of signal simultaneously

[0244] Taking Table 1 as an example, if the wake-up circuit and the main circuit of the terminal device work in band#1 and band#2 respectively, such as the wake-up circuit works in band#1 and the main circuit works in band#2, or the wake-up circuit works in band#2 and the main circuit works in band#1, then the terminal device can receive the first type of signal and the second type of signal simultaneously, that is, the terminal device can receive signals through the main circuit and the wake-up circuit at the same time; if the wake-up circuit and the main circuit of the terminal device work in band#3 and band#4 respectively, such as the wake-up circuit works in band#3 and the main circuit works in band#4, or the wake-up circuit works in band#4 and the main circuit works in band#1, then the terminal device cannot receive the first type of signal and the second type of signal simultaneously, that is, the terminal device cannot receive signals through the main circuit and the wake-up circuit at the same time.

[0245] Among them, the main circuit working in band#1 means that the frequency of receiving signals through the main circuit is this band#1; similarly, the wake-up circuit working in band#2 means that the frequency of receiving signals through the wake-up circuit is this band#2. This will not be explained further below.

[0246] It can be understood that Table 1 is for illustrative purposes and is not limited thereto. For example, it can include more numbers of band combinations. For another example, the band combinations can include more numbers of bands.

[0247] In this case, the capability information reported by the terminal device can be the capability information of a certain band combination, or the capability information of some band combinations. Taking Table 1 as an example, the terminal device can report the capability information associated with the band combination of band#1 and band#2, and / or, the terminal device can report the capability information associated with the band combination of band#3 and band#4. In addition, in the reported capability information, the capability information and the information of the associated band combination (such as the identifier of the associated band combination) can be carried; or, the capability information can also be directly carried. At this time, it can be defaulted that the network side (such as the network device) knows which band combination the capability information is associated with.

[0248] In the second possible case, the capability information is of one band, or rather, the capability information is associated with the band. In this case, it can be defaulted or predefined that the main circuit and the wake-up circuit work in the same band.

[0249] As an example, the capability information and the band can exist in the form of a table, a function, text, or a string, such as for storage or transmission. Table 2 below shows an example of presenting the capability information and the band in tabular form.

[0250] Table 2

[0251] band Capability information band#1 Can receive the first type of signal and the second type of signal simultaneously band#2 Can receive the first type of signal and the second type of signal simultaneously band#3 Cannot receive the first type of signal and the second type of signal simultaneously

[0252] Taking Table 2 as an example, if the terminal device operates in band #1 or band #2, that is, the frequency of the signal is band #1 or band #2, then the terminal device can receive the first type of signal and the second type of signal simultaneously, that is, the terminal device can receive signals through the main circuit and the wake-up circuit simultaneously; if the terminal device operates in band #3, that is, the frequency of the signal is band #3, then the terminal device cannot receive the first type of signal and the second type of signal simultaneously, that is, the terminal device cannot receive signals through the main circuit and the wake-up circuit simultaneously.

[0253] It can be understood that Table 2 is for illustrative purposes and is not limited thereto. For example, it can include a greater number of bands. For another example, the bands that can receive the first type of signal and the second type of signal simultaneously can be listed together, and the bands that cannot receive the first type of signal and the second type of signal simultaneously can be listed together.

[0254] In this case, the capability information reported by the terminal device can be the capability information of a certain band (such as a certain band supported by the terminal device), or the capability information of certain bands (such as certain bands supported by the terminal device). Taking Table 2 as an example, the terminal device can report at least one of the following capability information associated with the bands: band #1, band #2, or band #3. In addition, in the reported capability information, the information of the capability information and the associated band (such as the identifier of the associated band) can be carried; or, the capability information can be directly carried. In this case, it can be defaulted that the network side (such as the network device) knows which band the capability information is associated with; or, the band information can be directly carried. In this case, it can be defaulted that the network side knows the capability information of the band.

[0255] It can be understood that the above examples are given by taking bands and band combinations as examples and are not limited thereto. For example, the band can also be replaced by other frequency domain units.

[0256] It can be understood that in the embodiments of the present application, "receive" can also be replaced by "detect" or "read" or "monitor". For example, "receive a reference signal" can also be replaced by "detect a reference signal" or "read a reference signal" or "monitor a reference signal".

[0257] It can also be understood that in some of the above embodiments, the main circuit and the wake-up circuit are taken as examples for illustrative purposes, and the present application is not limited thereto. For example, the "wake-up circuit" can also be replaced with the "first module", or can also be replaced with the "wake-up link", or can also be replaced with "being in the first state", or can also be replaced with "being in the first mode". For example, "the terminal device receives a signal through the wake-up circuit" can also be replaced with "the terminal device receives a signal through the first module or the terminal device receives a signal on the wake-up link". The "main circuit" can also be replaced with the "second module", or can also be replaced with the "main link", or can also be replaced with "being in the second state", or can also be replaced with "being in the second mode". For example, "the terminal device receives a signal through the main circuit" can also be replaced with "the terminal device receives a signal through the second module or the terminal device receives a signal on the main link".

[0258] It can also be understood that in some of the above embodiments, "transmission" is mentioned. Without special explanation, transmission includes receiving and / or sending. For example, transmitting a signal can include receiving a signal and / or sending a signal.

[0259] It can also be understood that in the embodiments of the present application, the interaction between the terminal device and the network device is mainly taken as an example for illustrative purposes. The present application is not limited thereto. The terminal device can be replaced with the receiving-end device, and the receiving-end device can be the terminal device or the network device; the network device can be replaced with the sending-end device, and the sending-end device can be the terminal device or the network device. Exemplarily, the "terminal device" can be replaced with the "first terminal device", and the "network device" can be replaced with the "second terminal device".
