Description

Technology Field

[0001] This application claims priority to Chinese Patent Application No. 202410076894.6, filed with the Chinese Intellectual Property Office on January 18, 2024, titled "Signal Transmission Method and Communication Apparatus," the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the field of wireless communication, and more specifically, to a signal transmission method and a communication device. Background Technology

[0003] The terminal device may receive a wake-up signal via a separate low-power small circuit, for example, a wake-up radio (WUR), and the main circuit may be in a sleep state. After the terminal device detects the wake-up signal via the WUR, the terminal device triggers the wake-up of the main circuit. After the main circuit is woken up, the terminal device may receive another signal, for example, a reference signal, via the main circuit.

[0004] The present application provides a signal transmission method and a communication device, so that after a wake-up signal is introduced, the terminal device can also receive a reference signal without missing the detection of the wake-up signal.

[0005] According to a first embodiment, a signal transmission method is provided. The method may be performed by a device. The device may be a device (e.g., a terminal device) or a component of a device (e.g., a chip, a chip system, or a circuit). This is not limited in the present application.

[0006] The above method may include the steps of: determining a time domain resource of a reference signal and a time domain resource of a wake-up signal; receiving the reference signal on part or all of the time domain resource of the reference signal; and monitoring the wake-up signal on the time domain resource of the wake-up signal.

[0007] Based on the technical solution described above, a terminal device is used as an example. Considering that the terminal device can receive a wake-up signal through a wake-up circuit or receive another signal (e.g., a reference signal) through a main circuit, the terminal device can determine the time-domain resources of the reference signal and the time-domain resources of the wake-up signal. In this way, the reference signal can be received on part or all of the time-domain resources of the reference signal based on the determined time-domain resources of the reference signal, and the wake-up signal can be monitored on the time-domain resources of the wake-up signal based on the determined time-domain resources of the wake-up signal. In this regard, the terminal device can receive the reference signal and monitor the wake-up signal on the determined time-domain resources. Additionally, the time-domain resources of the reference signal may be different from the time-domain resources of the wake-up signal. In this way, the transmission of two types of signals (i.e., a reference signal and a wake-up signal) is executed on different time domain resources, thereby avoiding the omission of signal detection (e.g., omission of wake-up signal detection) when the reference signal and the wake-up signal are transmitted simultaneously at one location. Compared to a terminal device receiving a reference signal or a wake-up signal at any location, the aforementioned technical solution can avoid the case where the terminal device misses detection of the wake-up signal.

[0008] Referring to the first embodiment, in some embodiment of the first embodiment, the reference signal is a signal used for measurement, and the wake-up signal is used to wake up at least one terminal device.

[0009] Referring to a first embodiment, in some embodiment of the first embodiment, the method further comprises the step of transmitting at least one capability information, each of which indicates whether a first type signal and a second type signal can be received simultaneously, the first type signal includes the wake-up signal, the second type signal includes the reference signal, on-off-keying (OOK) modulation is used for the first type signal, and non-OOK modulation is used for the second type signal.

[0010] Based on the technical solution described above, the terminal device may report capability information of the terminal device, for example, whether the terminal device can simultaneously receive a Type 1 signal and a Type 2 signal, or whether the terminal device can simultaneously receive a signal using OOK modulation and a signal using non-OOK modulation. This facilitates the network side (e.g., a network device) to perform corresponding processing based on the capability reported by the terminal device. For example, if the terminal device cannot simultaneously receive a Type 1 signal and a Type 2 signal, the network side may set a time domain resource of a corresponding reference signal and a time domain resource of a corresponding wake-up signal for the terminal device, thereby causing the time domain resource of the wake-up signal and the time domain resource of the reference signal to be out of sync with each other, so as to avoid missing the detection of the signal.

[0011] Referring to the first embodiment, in some embodiments of the first embodiment, one of the at least one capability information is per band or per band combination.

[0012] Based on the aforementioned technical solution, capability information may be band-specific or band combination-specific. In this way, the terminal device may report capability information for each band or band combination for different bands or different band combinations.

[0013] Referring to the first embodiment, in some embodiment of the first embodiment, the method further includes the step of receiving the first type signal through the wake-up circuit and receiving the second type signal through the main circuit.

[0014] Based on the technical solution described above, the first type signal and the second type signal may be signals received by the terminal device through different circuits. In this way, capability information reported by the terminal device may, alternatively, be whether the terminal device can simultaneously receive signals through the main circuit and the wake-up circuit.

[0015] Referring to the first embodiment, in some embodiments of the first embodiment, the method further includes the step of skipping monitoring the wake-up signal on the time domain resource of the reference signal.

[0016] Based on the technical solution described above, the terminal device may not monitor the wake-up signal on the time-domain resource of the reference signal. For example, the network device may set the time-domain resource of the reference signal for the terminal device. In this way, the network device transmits the reference signal on the time-domain resource of the reference signal and does not transmit the wake-up signal, and the terminal device may not monitor the wake-up signal on the time-domain resource of the reference signal. In this way, the terminal device and the network device align the time-domain resource location for measurement with the time-domain resource location for monitoring the wake-up signal, thereby avoiding the omission of detection of the wake-up signal and reducing the power consumption caused by the terminal device to monitor the wake-up signal.

[0017] Referring to the first embodiment, in some embodiment of the first embodiment, the step of determining the time domain resource of the reference signal includes the step of receiving configuration information, and the configuration information includes information regarding the time domain resource of the reference signal.

[0018] Referring to a first embodiment, in some embodiment of the first embodiment, the time domain resource of the reference signal comprises at least one time window; the time domain resource of the reference signal comprises a first time domain resource within the at least one time window, and the first time domain resource is a time domain resource in which the reference signal is transmitted.

[0019] Based on the technical solution described above, the terminal device can receive a reference signal on a concentrated time domain resource (i.e., at least one time window). In this way, when the terminal device receives a reference signal through a main circuit and receives a wake-up signal through a wake-up circuit, the number of switching cycles 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.

[0020] Referring to the first aspect, in some embodiment of the first aspect, the time domain resource of the reference signal includes the at least one time window, and the method further includes the step of skipping monitoring the wake-up signal within the at least one time window.

[0021] Referring to the first embodiment, in some embodiment of the first embodiment, the time domain resource of the reference signal includes the first time domain resource within the at least one time window, and the method further includes the step of skipping monitoring the wake-up signal on the first time domain resource and / or monitoring the wake-up signal on a time domain resource other than the first time domain resource within the at least one time window.

[0022] Referring to the first embodiment, in some embodiment of the first embodiment, the method further comprises the step of receiving first instruction information, and the first instruction information indicates the at least one time window.

[0023] Optionally, the first instruction information comprises at least one start position of a time window, at least one start position of one of at least one time window, at least one end position of one of at least one time window, at least one end position of one of at least one time window, at least one length of one of at least one time window, a time interval between two adjacent time windows in at least one time window, or at least one offset. The offset represents an offset between one or more time windows and a connection status discontinuous reception CDRX.

[0024] Optionally, the offset between at least one time window and the connection state discontinuous reception CDRX comprises any one of the following: an offset between the start position of at least one time window and the start position of the CDRX OnDuration; an offset between the start position of at least one time window and the end position of the CDRX OnDuration; an offset between the start position of at least one time window and the middle position of the CDRX OnDuration; an offset between the start position of any one of at least one time window and the start position of the CDRX OnDuration; an offset between the start position of any one of at least one time window and the end position of the CDRX OnDuration; or an offset between the start position of any one of at least one time window and the middle position of the CDRX OnDuration.

[0025] Referring to the first embodiment, in some embodiment of the first embodiment, the at least one time window is predefined.

[0026] Optionally, an offset between at least one time window and the CDRX is predefined. For example, the offset includes an offset between the start position of at least one time window and the start position of the CDRX OnDuration, an offset between the start position of at least one time window and the end position of the CDRX OnDuration, an offset between the start position of at least one time window and the middle position of the CDRX OnDuration, an offset between the start position of any one of the at least one time windows and the start position of the CDRX OnDuration, an offset between the start position of any one of the at least one time windows and the end position of the CDRX OnDuration, or any one of the offsets between the start position of any one of the at least one time window and the middle position of the CDRX OnDuration.

[0028] Based on the aforementioned technical solution, the time domain resources of the reference signal and the time domain resources of the wake-up signal received by the terminal device are different. In this way, since the transmission of the wake-up signal is additionally performed during the transmission of the reference signal, the terminal device can receive the reference signal or the wake-up signal simultaneously, thereby avoiding the omission of detection of either the wake-up signal or the reference signal. Furthermore, the terminal device can determine the time domain resources of the reference signal based on the time domain resources of the wake-up signal; that is, the time domain resources of the reference signal are different from the time domain resources of the wake-up signal.

[0030] Referring to the first embodiment, in some embodiment of the first embodiment, the method further comprises the step of transmitting second instruction information, wherein the second instruction information indicates a time domain resource expected by the terminal device for the transmission of the reference signal.

[0031] Based on the aforementioned technical solution, the terminal device may report to the network device the expected time domain resources for the transmission of a reference signal. In this way, the network device may determine the time domain resources of the reference signal (e.g., the aforementioned time window) based on the time domain resources expected by the terminal device within the second instruction information. In this way, the set time domain resources of the reference signal can better satisfy the requirements of the terminal device.

[0032] Referring to the first aspect, in some embodiments of the first aspect, the time domain resources of the wake-up signal are discontinuous, or the time domain resources of the wake-up signal are periodic.

The scenarios in which the network device and terminal device are located are not limited to the embodiments of the present application.

[0101] First, a communication system applicable to the embodiments of the present application is briefly described below with reference to FIG. 1.

[0102] For example, FIG. 1 is a drawing of a wireless communication system applicable to one embodiment of the present application. As illustrated in FIG. 1, the wireless communication system includes a wireless access network (100). The wireless access network (100) may be a next-generation (e.g., 6G or later) wireless access network or a conventional (e.g., 5G, 4G, 3G, or 2G) wireless access network. One or more terminal devices (120a to 120j, collectively referred to as 120) may be interconnected within the wireless access network (100) or connected to one or more network devices (110a and 110b, collectively referred to as 110). Network elements of the wireless communication system are connected via an interface (e.g., NG or Xn) or an air interface.

[0103] When a network device communicates with a terminal device, the network device may manage one or more cells, and one cell may include at least one terminal device. A cell may be understood as an area within the coverage of the network device's wireless signal.

[0104] FIG. 1 is for drawing purposes only. A wireless communication system may further include other devices, for example, a core network device, a wireless relay device, and / or a wireless backhaul device, which are not illustrated in FIG. 1.

[0105] For ease of understanding of the embodiments of the present application, the terms of the present application are briefly explained.

[0106] 1. Wake-up circuit: This is also referred to as a wake-up receiver / radio (WUR), a low-power wake-up receiver (LP-WUR), or a wake-up module, and can be understood as a distinct low-power small circuit, for example, a circuit used by a terminal device in an idle state. The low-power small circuit can be implemented through a distinct small circuit or a chip having a simple structure, and has low power consumption. It should be understood that the wake-up circuit is named merely for distinction, and that the specific designation does not limit the scope of protection of this application. For example, without loss of generality, the wake-up circuit may also be described as the first circuit (or first module). For consistency of description, the term wake-up circuit will be used below.

[0107] A signal received by a terminal device through a wake-up circuit may be referred to as a transmission over a wake-up link. A wake-up link represents a connection relationship between a terminal device and a network device and is a logical concept rather than a physical entity. It should be understood that the wake-up link is named merely for distinction and that this specific designation does not limit the scope of protection of this application. For example, without loss of generality, the wake-up link may also be described as a first link. For consistency of description, the term wake-up link will be used below.

[0108] For the sake of distinction, for example, a signal received by a terminal device through a wake-up circuit may be referred to as a Type 1 signal. It is understood that the Type 1 signal is named merely for the sake of distinction, and that this specific designation does not limit the scope of protection of this application. For example, without loss of generality, the Type 1 signal may also be referred to as a signal. For the sake of consistency in description, the Type 1 signal is used below.

[0109] For example, the first type signal includes a wake-up signal (WUS) and / or a synchronization signal.

[0110] A wake-up signal may be used to wake up at least one terminal device. Waking up a terminal device indicates waking up the main circuit of the terminal device. For example, the wake-up signal represents paging-related information, and the paging-related information may include, for example, whether a single terminal device or a group of terminal devices is being paged. The wake-up signal may also be referred to as a low-power wake-up signal (LP-WUS), and such specific designation does not limit the scope of protection of the present application.

[0111] The synchronization signal can be used to implement synchronization functions and can be additionally used to implement some measurement functions performed through the wake-up circuit, for example, radio resource management (RRM) measurements. The synchronization signal may also be referred to as a low-power synchronization signal (LP-SS).

[0112] 2. Main Circuit: This is also referred to as the main receiver (MR) or main module and can be understood as the circuit used when the terminal device performs data transmission normally or when the terminal device performs data transmission while connected. When the terminal device performs data transmission through the main circuit, power consumption is high. It should be understood that the main circuit is named merely for distinction and that its specific designation does not limit the scope of protection of this application. For example, without loss of generality, the main circuit may also be described as the second circuit (or second module). For consistency of description, the term main circuit will be used below.

[0113] A signal received by a terminal device through the main circuit may be referred to as a transmission over the main link. The main link represents the connection relationship between the terminal device and the network device and is a logical concept rather than a physical entity. It should be understood that the main link is named merely for distinction and that this specific designation does not limit the scope of protection of this application. For example, without loss of generality, the main link may also be described as a second link. For consistency of description, the term main link will be used below.

[0114] In the following, for the purpose of distinction, the signal received by the terminal device through the main circuit is indicated as a Type 2 signal.

[0115] For example, Figure 2 is a diagram of the main circuit and the wake-up circuit.

[0116] As illustrated in FIG. 2, a terminal device may receive (or detect or monitor) a Type 1 signal (e.g., a wake-up signal) through a wake-up circuit, and the terminal device may receive a Type 2 signal through a 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 may remain in an off state (or sleep state). When the terminal device detects the wake-up signal, the terminal device triggers the wake-up of the main circuit, that is, enables the main circuit to become on (or referred to as an operating state or active state) or to be switched to an on state. After the main circuit is turned on, the terminal device may perform the transmission of the Type 2 signal through the main circuit.

[0117] 3. Relationship between wake-up circuit and main circuit: Considering size and cost, the wake-up circuit and the main circuit can reuse the same antenna (or physical antenna).

[0118] Referring to Fig. 3, two possible ways in which the wake-up circuit and the main circuit are connected to the antenna are described below.

[0119] Method 1: The antenna is connected separately to the wake-up circuit and the main circuit. In this case, the wake-up circuit and the main circuit can receive the signal simultaneously.

[0120] For example, FIG. 3 is a diagram showing a wake-up circuit and a main circuit connected to an antenna. As shown in FIG. 3(a), the antenna is connected separately to the wake-up circuit (indicated as LR in FIG. 3) and the main circuit (indicated as MR in FIG. 3). In this case, the power of the signal received by the antenna is divided. Consequently, the signal power of the wake-up circuit and the main circuit is attenuated (e.g., by 3 dB).

[0121] Method 2: The antenna is connected to the wake-up circuit or the main circuit via a switch. In this case, the wake-up circuit and the main circuit may not receive the signal simultaneously, or they may receive the signal simultaneously. As illustrated in FIG. 3 (b) or (c), the antenna may be connected to the wake-up circuit or the main circuit via a switch. In this case, because a switch is introduced, the power of the signal received by the antenna is attenuated, but the attenuation is smaller than the attenuation caused by splitting. In FIG. 3 (b), because the switch is connected to the wake-up circuit or the main circuit, the wake-up circuit and the main circuit do not receive the signal simultaneously. Additionally, considering that the wake-up circuit and the main circuit may be related to the operating frequency, when Method 2 is used, if the wake-up circuit and the main circuit operate at different frequencies, the wake-up circuit and the main circuit may receive the signal simultaneously. As illustrated in FIG. 3 (c), when the wake-up circuit operates in band (1), the main circuit operates in band (2), and the terminal device receives signals from band (1) and band (2) using different antennas, and even if the connection is made through a switch, the wake-up circuit and the main circuit can still receive signals simultaneously.

[0122] From the above description, it can be seen that 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.

[0123] 4. Reference signal (RS) and reference signal resource: The reference signal can be used for channel measurement, beam measurement, channel estimation, etc. The reference signal resource can be used to establish the transmission properties of the reference signal, e.g., time-frequency resource location, port mapping relationship, power factor, and scrambling code. A transmitting device can transmit the reference signal based on the reference signal resource, and a receiving device can receive the reference signal based on the reference signal resource.

[0124] 5. Time domain resource: Data or information may be carried in a resource. In the time domain, a resource may be referred to as a time domain resource. A time domain resource may include one or more time domain units (or may be referred to as a time unit). A time domain unit may be a symbol, an orthogonal frequency division multiplexing (OFDM) symbol, a mini-slot, a slot, a partial slot, a subframe, a wireless frame, etc.

[0125] 6. Measurement: A connected terminal device can perform various types of measurements. Specifically, measurements can be performed based on a reference signal. Several types are briefly described below.

[0126] (1) Radio link monitoring (RLM) and beam failure detection (BFD)

[0127] The procedure for a terminal device to perform RLM is similar to the procedure for a terminal device to perform BFD. In the following, RLM is used as an example to explain possible steps.

[0128] Step 1: The terminal device receives a reference signal. For example, the reference signal may be a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS).

[0129] By utilizing the radioLinkMonitoringConfig within the bandwidth part-downlink dedicated (BWP-DownlinkDedicated), UE-specific settings can be performed on the resources used for RLM. In addition to the resources used for RLM, the resources configured by the network side using the radioLinkMonitoringConfig include other resources, such as those used for BFD. For example, radioLinkMonitoringConfig includes N LR-RLM There are reference signal resources. For example, maximum N RLM Reference signal resources are used for RLM, and up to two reference signal resources are used for BFD. The resources used for RLM and BFD may be the same or different. N LR-RLM and N RLM The value of is related to the maximum amount of reference signal (e.g., SSB).

[0130] Additionally, if the reference signal (RadioLinkMonitoringRS) used for RLM is not configured for the terminal device, but the transmission configuration indication (TCI) status (TCI status) of the physical downlink control channel (PDCCH) includes one or more CSI-RSs, the terminal device may perform RLM using these CSI-RSs. Specifically, the CSI-RSs used to perform RLM may be all or part of the CSI-RSs according to a specific order agreed upon in the protocol. This is not limited to the present specification.

[0131] Step 2: The terminal device calculates the quality (or referred to as radio link quality) based on each reference signal.

[0132] For example, a measurement metric (or referred to as a measurement quantity) includes at least one of reference signal received power (RSRP), reference signal received quality (RSRQ), or signal-to-noise ratio (SNR).

[0133] When calculating quality, the terminal device can perform the calculation within a specific period (e.g., an evaluation period). To achieve a good filtering effect, multiple samples are generally used (the specific amount of samples used varies depending on the implementation of the terminal device). If the reference signal is an SSB, the time period is T Evaluate_out_SSB and T Evaluate_in_SSB Includes. If the reference signal is CSI-RS, the time period is T Evaluate_out_CSI-RS and T Evaluate_in_CSI-RSIncludes

[0134] Step 3: The terminal device calculates the quality based on each reference signal and assigns a corresponding threshold value (e.g., Q out and Q in Compares with ). The threshold values ​​corresponding to different reference signals can each have respective values. For example, for a single terminal device, four parameters Q out_SSB , Q in_SSB , Q out_CSI-RS and Q in_CSI-RS can exist simultaneously. Q out_SSB is T Evaluate_out_SSB It is used to compare with the quality calculated based on the reference signal of the time period, and Q in_SSB is T Evaluate_in_SSB It is used to compare with the quality calculated based on the reference signal of the time period, and Q out_CSI-RS is T Evaluate_out_CSI-RS It is used to compare with the quality calculated based on the reference signal of the time period, and Q in_CSI-RS is T Evaluate_in_CSI-RS It is used to compare with the quality calculated based on the reference signal of the time period.

[0135] Step 4: The physical layer within the terminal device directs the radio resource control (RRC) layer to out-of-sync (OOS) or in-sync (IS) based on the comparison result. Specifically, the quality of all reference signals is a threshold value (Q out If lower than ), OOS is indicated, and the quality of at least one reference signal is Q in If higher, IS is indicated, and in other cases, no instruction may be transmitted.

[0136] The steps described above are examples for illustrative purposes. They are not limited to the embodiments of the present application.

[0137] (2) Channel state information (CSI) measurement

[0138] For example, CSI measurement includes the following steps.

[0139] Step 1: The terminal device receives a reference signal.

[0140] Step 2: The terminal device measures a reference signal. In different cases (e.g., intra-frequency or inter-frequency, different frequency ranges, and different discontinuous reception (DRX) cycle lengths), the requirements for the measurement cycle differ. In this case, the measurement location within a cycle is not specified in the protocol.

[0141] Step 3: The terminal device reports the measurement results. Typically, the terminal device can report a CSI report via a physical uplink control channel (PUCCH).

[0142] (3) RRM measurement

[0143] For example, RRM measurements (or may be referred to as cell measurements) include serving cell measurements and neighbor cell measurements. For example, neighbor cell measurements include at least one of in-frequency measurements, inter-frequency measurements, and inter-radio access technology (inter-RAT) measurements.

[0144] Similarly, 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.

[0145] The foregoing briefly describes some types of measurements, primarily when the terminal device is connected. For different types of measurements, measurement requirements may differ; for example, measurement cycles may differ.

[0146] In the connected state, services to the terminal device typically arrive more frequently than in the idle state. Therefore, the main circuit of the terminal device is turned on more frequently to receive and transmit data. To reduce the complexity of the protocol design, in a possible implementation, the main circuit is used to perform some measurement behaviors in the connected state, and the measurements include, but are not limited to, RLM, BFD, CSI measurements, or RRM measurements.

[0147] However, as described above, the wake-up circuit and the main circuit of the terminal device may not receive signals simultaneously. In this case, the terminal device cannot simultaneously receive a wake-up signal using the wake-up circuit and perform a measurement using the main circuit (or receive a reference signal used for the measurement using the main circuit). In this case, the following may occur: the network side transmits a wake-up signal at the time-domain location where the terminal device performs the measurement, and the terminal device may miss the detection of the wake-up signal.

[0148] In this regard, the present application provides a solution. A time-domain location used for measurement is set or defined, that is, the terminal device performs the measurement at the time-domain location, and the network device does not transmit a wake-up signal at the time-domain location. In this way, the terminal device and the network device can align the time-domain location where the terminal device performs the measurement through the main circuit, thereby avoiding the omission of the wake-up signal detection.

[0149] Before describing the means of solution of the present application, the following description is provided.

[0150] (1) In this application, “instruction” may include direct instruction, indirect instruction, explicit instruction, and implicit instruction. When instruction information is described as indicating A, this may be understood as instruction information including A, directly indicating A, or indirectly indicating A.

[0151] In this application, information indicated by the directing information is referred to as the indicated information. In a particular implementation, the indicated information may be indicated in many ways, for example, in the following ways, but is not limited thereto: the indicated information may be indicated directly. For example, the indicated information or an index of the indicated information may be indicated. Alternatively, the indicated information may be indicated indirectly by indicating other information, and there is an association between the other information and the indicated information. Alternatively, only a part of the indicated information may be indicated, and other parts of the indicated information may be known or pre-agreed upon. For example, to reduce display overhead to some extent, specific information may be indicated alternatively by using a pre-agreed arrangement of multiple pieces of information (e.g., specified in a protocol). Additionally, the indicated information may be transmitted as a whole or may be divided into multiple sub-information for separate transmission, and the transmission periods and / or transmission times of these sub-information may be the same or different.

[0152] (2) In this application, the expression " / " indicates that the associated objects are in an "or" relationship. For example, A / B may represent A or B. The expression "and / or" indicates that the associated objects may be in an "and" relationship or an "or" relationship. For example, A and / or B may represent the following cases: only A exists, only B exists, and both A and B exist, wherein A and B may be one or more. "At least one of the following" or a similar expression indicates any combination of the listed items. For example, at least one of A, B, and / or C may represent the following cases: only A exists, only B exists, only C exists, both A and B exist, both B and C exist, both A and C exist, and all A, B, and C exist. A, B, and C may be singular or plural.

[0153] (3) In this application, “transmission” and “reception” indicate the direction of signal transmission. For example, “transmitting information to XX” may be understood as the destination of the information being XX, and may include direct transmission via a wireless interface or indirect transmission via a wireless interface by another unit or module. “Receiving information from YY” may be understood as the source of the information being YY, and may include direct reception from YY via a wireless interface or indirect reception from YY via a wireless interface by another unit or module. “Transmission” may alternatively be understood as the “output” of a chip interface, and “reception” may alternatively be understood as the “input” of a chip interface. In other words, transmission and reception may be performed between devices, for example, between a network device and a terminal device, or within a device, for example, between components, modules, chips, software modules, or hardware modules within the device via a bus, cable, or interface.

[0154] (4) In the embodiments of the present application, unless otherwise stated or there is a logical conflict, terms and / or descriptions in different embodiments may be consistent and mutually referenced, and technical features in different embodiments may be combined based on their internal logical relationships to form new embodiments.

[0155] (5) In this application, “first” and “second” are used merely for convenience of explanation and to distinguish objects, but are not intended to limit the scope of the embodiments of this application and are not used to describe a series of features. It should be understood that since objects described in this manner are interchangeable in appropriate circumstances, means of solution other than the embodiments of this application may be described.

[0156] Hereinafter, the methods provided in the embodiments of the present application will be described in detail with reference to the attached drawings. The embodiments provided in the present application may be applied to the scenarios illustrated in the drawings above. This is not limited to this.

[0157] For example, FIG. 4 is a diagram of a signal transmission method (400) according to one embodiment of the present application. For convenience of explanation, the method (400) is described below as an example in which it is performed by a terminal device. It may be understood that the method (400) may alternatively be performed by a component of the terminal device, e.g., a chip, a chip system, or a circuit. This is not limited in the specification. A step described below as being performed by a single execution body may alternatively be performed by a plurality of execution bodies. These execution bodies may be logically and / or physically separated. The method (400) illustrated in FIG. 4 may include the following steps.

[0158] The method (400) includes step (420) and step (430). Optionally, the method (400) includes step (410).

[0159] 410: The terminal device determines the time domain resource of the reference signal and the time domain resource of the wake-up signal.

[0160] For example, a reference signal is used for measurement. Specifically, a terminal device may perform a measurement based on the reference signal, that is, the terminal device performs a measurement based on the reference signal through the main circuit. For example, the measurement includes at least one of the following: RLM, BFD, channel measurement (e.g., CSI measurement), RRM measurement (or may be referred to as cell measurement), beam measurement, etc. For the aforementioned measurement items, refer to the relevant description in the above-mentioned terminology section. Furthermore, specific measurement methods are not limited in the embodiments of the present application.

[0161] The time domain resource of the reference signal represents a time domain resource where the reference signal can be received or a time domain resource where a measurement can be performed.

[0162] Determining the time-domain resource of the reference signal can alternatively be replaced by determining the time-domain resource that is not used to monitor the wake-up signal.

[0163] For example, a wake-up signal is used to wake up at least one terminal device. Refer to the relevant description above for the wake-up signal.

[0164] Determining the time domain resource of the wake-up signal can alternatively be replaced by determining the time domain resource used to monitor the wake-up signal.

[0165] For example, the modulation method of the wake-up signal is OOK modulation, and the modulation method of the reference signal is non-OOK modulation. For example, 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.

[0166] The modulation scheme of the wake-up signal being OOK modulation can alternatively be replaced with the following: within the time interval corresponding to the wake-up signal, energy exists at some time domain locations and energy does not exist at some time domain locations; or energy at some time domain locations is greater than a first threshold and energy at some time domain locations is less than a second threshold, and 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 symbols is greater than or equal to the first threshold and the signal amplitude of the second symbols is less than or equal to the second threshold, where X is an integer greater than 0, X1 and X2 are integers greater than or equal to 0, and X1 + X2 = X.The condition that the signal amplitude of the first symbol is greater than or equal to a first threshold and the signal amplitude of the second symbol is less than or equal to a second threshold may be replaced with any of the following: the signal amplitude of the first symbol is greater than the signal amplitude of the second symbol; in a preset 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; in a preset 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 a first threshold and the signal power of the second symbol is less than or equal to a second threshold; in a preset period, the signal power of the first symbol is greater than or equal to a first threshold and the signal power of the second symbol is less than or equal to a second threshold; the signal level value of the first symbol is greater than the signal level value of the second symbol; in a preset 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 a first threshold and the signal level value of the second symbol is less than or equal to a second threshold; In a preset 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 represents (or corresponds to or expresses) a first bit value, and the second symbol represents (or corresponds to or expresses) a second bit value. The first bit value is different from the second bit value. For 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".

[0167] 420: A terminal device receives a reference signal on part or all of the time domain resources of the reference signal.

[0168] The terminal device may be a terminal device in a connected state.

[0169] In step (410), the time domain resource of the reference signal is a time domain resource that can be used (or is available) by the terminal device to receive the reference signal. During actual communication, the terminal device may receive the reference signal on a part of the time domain resource of the reference signal, or the terminal device may receive the reference signal on the entire time domain resource of the reference signal.

[0170] For example, the time domain resource of a reference signal includes N time domain units, where N is an integer greater than 1. A terminal device receives the reference signal at N1 of the N time domain units, where N1 is an integer greater than or equal to 0 and N1 is less than or equal to N. When N1 = 0, it can be understood that this indicates that the terminal device does not receive the reference signal on the time domain resource of the reference signal.

[0171] 430: The terminal device monitors the wake-up signal on the time domain resource of the wake-up signal.

[0172] Optionally, the terminal device includes a first module and a second module. The terminal device monitors a wake-up signal through the first module (or referred to as 'use') and receives a reference signal through the second module (or referred to as 'use'). Specifically, at step (420), the terminal device receives the reference signal on part or all of the time domain resources of the reference signal through the second module; and at step (430), the terminal device monitors the wake-up signal on the time domain resources of the wake-up signal through the first module.

[0173] For example, the power consumption of the first module may be less than the power consumption of the second module. The first module may be, for example, the wake-up circuit in FIG. 2 or a receiving module of the wake-up circuit. The second module may be, for example, the main circuit in FIG. 2 or a receiving module of the main circuit. Refer to the relevant descriptions above for the main circuit and the wake-up circuit. The main circuit and the wake-up circuit will be described below by way of example.

[0174] The following describes the relevant means of resolving the time-domain resources of the reference signal and the time-domain resources of the wake-up signal. For example, the time-domain resources of the reference signal and the time-domain resources of the wake-up signal include the following three means of resolving.

[0175] Solution 1: A network device sets a time-domain resource of a reference signal. A terminal device does not monitor a wake-up signal on the time-domain resource of the reference signal. Correspondingly, the network device does not transmit a wake-up signal on the time-domain resource of the reference signal. In this regard, the time-domain resource of the reference signal in step (410) is the time-domain resource of the reference signal set by the network device. The time-domain resource of the reference signal set by the network device indicates that the network device transmits the reference signal on the time-domain resource of the reference signal set. In the case of the terminal device, it should be noted that whether the reference signal is received on the set time-domain resource depends on the implementation of the terminal device, for example, the measurement requirements of the terminal device. For example, the terminal device may receive the reference signal on the entire time-domain resource of the reference signal. In another example, the terminal device may receive the reference signal on a part of the time-domain resource of the reference signal.

[0176] In this solution, the network device can set the time-domain resource of the reference signal used for measurement with respect to the terminal device. In this way, the network device transmits the reference signal on the time-domain resource of the reference signal and does not transmit the wake-up signal, and the terminal device may not monitor the wake-up signal on the time-domain resource of the reference signal. In this way, the terminal device and the network device can align the time-domain resource locations for measurement to avoid missing detection of the wake-up signal, and power consumption caused by the terminal device to monitor the wake-up signal can be reduced.

[0177] For example, FIG. 5 is a diagram of a solution means 1 applicable to one embodiment of the present application. As illustrated in FIG. 5, a network device sets a time domain resource of a reference signal that can be used for measurement with respect to a terminal device (i.e., the time domain resource of the reference signal in step (410)). For simplicity, the time domain resource is referred to as time domain resource #1. The network device does not transmit a wake-up signal on time domain resource #1, and in the process of monitoring the wake-up signal, the terminal device does not monitor the wake-up signal on time domain resource #1. Specifically, it can be assumed that the terminal device can perform a measurement at the location of time domain resource #1. Accordingly, at the location of time domain resource #1, the network device does not transmit a wake-up signal, and the terminal device does not monitor the wake-up signal. However, for example, it can be seen from FIG. 5 that the terminal device actually receives the reference signal on a part of the time domain resource #1 for measurement, for example, the time domain resource where the measurement is actually performed in FIG. 5 (i.e., a part of the time domain resource of the reference signal in step (420)).

[0178] The "time domain resource originally used to monitor the wake-up signal" illustrated in FIG. 5 includes at least the following two cases.

[0179] Where possible, the "time domain resource originally used to monitor the wake-up signal" illustrated in FIG. 5 is any time domain resource used to monitor the wake-up signal. For example, a terminal device performs continuous monitoring of the wake-up signal on the time domain resource originally used to monitor the wake-up signal illustrated in FIG. 5. Based on Solution 1, the terminal device may stop monitoring the wake-up signal on time domain resource #1 (or no longer monitor the wake-up signal) and continue monitoring the wake-up signal on another time domain resource.

[0180] In other possible cases, the "time domain resource originally used to monitor the wake-up signal" illustrated in FIG. 5 is part of all time domain resources used to monitor the wake-up signal. For example, a terminal device performs duty cycle monitoring of the wake-up signal on the time domain resource originally used to monitor the wake-up signal illustrated in FIG. 5. In another example, a network device sets up a plurality of time domain resources for the wake-up signal, and the plurality of time domain resources include the "time domain resource originally used to monitor the wake-up signal" illustrated in FIG. 5. Based on Solution 1, the terminal device may stop monitoring the wake-up signal on time domain resource #1 (or no longer monitor the wake-up signal) and continue monitoring the wake-up signal on another time domain resource.

[0181] Based on solution means 1, additionally optionally, the method (400) further comprises: a terminal device receives configuration information, wherein the configuration information includes information about a time domain resource of a reference signal.

[0182] For example, configuration information can be carried in radio resource control (RRC) signaling.

[0183] For example, information regarding the time domain resources of a reference signal includes at least one of the following: the start position of the reference signal in the time domain, the end position of the reference signal in the time domain, the time domain length of the reference signal in the time domain (e.g., the amount of time domain units occupied by the reference signal), or the index of the time domain units occupied by the reference signal.

[0184] Solution 2: At least one time domain resource is set or defined, and on at least one time domain resource, the terminal device receives a reference signal and does not monitor a wake-up signal. In this regard, the time domain resource of the reference signal in step (410) is at least one time domain resource.

[0185] In this solution, the terminal device performs measurements on a concentrated time domain resource to reduce the number of switching cycles of the terminal device's main circuit / wake-up circuit (or sleep / wake-up), thereby reducing the power consumption of the terminal device.

[0186] At least one time domain resource may be in the form of a time window, a time domain unit, or a time domain length. This is not limited to the present specification. Two implementation examples are described below using a time window as an example.

[0187] In a first possible embodiment, the time domain resource of the reference signal in step (410) includes at least one time window. In this regard, in step (420), the terminal device receives the reference signal on part or all of the time domain resource within at least one time window. Additionally, the terminal device does not monitor the wake-up signal in at least one time window. Additionally, the network device does not transmit the wake-up signal in at least one time window.

[0188] For example, FIG. 6 is a diagram of solution means 2 applicable to one embodiment of the present application. As illustrated in FIG. 6, a terminal device may receive a reference signal in a time window, and in the process of monitoring a wake-up signal, the terminal device does not monitor the wake-up signal in the time window. Furthermore, it can be seen from FIG. 6 that, in practice, for example, the terminal device receives the reference signal and performs the measurement at two time domain locations within the time window (i.e., the time domain resources of the reference signal actually used for measurement, illustrated in FIG. 6). For example, FIG. 6 illustrates a single time window. It can be understood that, in practice, there may be multiple time windows. Multiple time windows may be discontinuous. For example, multiple time windows may be periodic, that is, the time interval between all two adjacent time windows in multiple time windows may be the same.

[0189] In a second possible embodiment, in step (410), the time domain resource of the reference signal comprises a portion of the time domain resource within at least one time window (for distinction, the portion of the time domain resource is referred to as the first time domain resource). In this regard, in step (420), the terminal device may receive the reference signal on a portion or the whole of the first time domain resource. The first time domain resource is a time domain resource set for the reference signal, that is, the first time domain resource is a time domain resource where the reference signal is transmitted, that is, the network device transmits the reference signal on the first time domain resource. During actual communication, the terminal device may receive the reference signal on a portion of the first time domain resource or receive the signal on the whole of the first time domain resource.

[0190] Additionally, the terminal device does not monitor a wake-up signal on a first time domain resource within at least one time window. In other words, in at least one time window, the terminal device monitors a wake-up signal on a time domain resource other than the first time domain resource. Additionally, in at least one time window, the network device does not transmit a wake-up signal on a first time domain resource within at least one time window.

[0191] For example, FIG. 7 is another illustration of solution means 2 applicable to one embodiment of the present application. As illustrated in FIG. 7, in one time window, the first time domain resource includes three locations, and in the process of monitoring the wake-up signal, the terminal device does not monitor the wake-up signal at the three locations. The terminal device may monitor the wake-up signal at other locations within the time window. Additionally, the terminal device may receive a reference signal at three locations, and it can be seen from FIG. 7 that the terminal device actually receives the reference signal at two of the three locations (i.e., the time domain resource of the reference signal actually used for measurement, illustrated in FIG. 7) and performs a measurement based on the reference signal. For example, FIG. 7 illustrates one time window. It can be understood that there may actually be multiple time windows. Also, for example, FIG. 7 illustrates the case where the first time domain resource includes three discontinuous time domain resources. This is not limited in the specification. In fact, the first time domain resource may be continuous, or the first time domain resource may include more or fewer discontinuous time domain resources.

[0192] For the time domain resources originally used to monitor the wake-up signal as resources of the terminal device in FIGS. 6 and 7, refer to the relevant description of Solution 1. Details are not described again in this specification.

[0193] The following describes a relevant solution for at least one time-domain resource (i.e., a time window) mentioned in Solution 2. Below, two implementation examples are described using a time window as an example.

[0194] In a first possible implementation, the time window is set by a network device.

[0195] Based on this method, optionally, the method (400) further comprises: a terminal device receives first instruction information, wherein the first instruction information indicates at least one time window.

[0196] Optionally, the first instruction information comprises at least one start position of a time window, at least one start position of one of at least one time window, at least one end position of a time window, at least one end position of one of at least one time window, at least one length of a time window, at least one length of one of at least one time window, a time interval between two adjacent time windows in at least one time window, or at least one offset. The offset represents the offset between at least one time window and a connected DRX (CDRX). The following briefly describes a few examples.

[0197] Example 1: The first instruction information includes the starting position of at least one time window.

[0198] For example, the first instruction information includes the starting position of the first time window among at least one time window. In this case, the terminal device can learn the starting position of each time window based on the interval between time windows and the starting position of the first time window. The interval between time windows may be predefined or may be included in the first instruction information.

[0199] Example 2: The first instruction information includes an end position of at least one time window.

[0200] Example 2 is similar to Example 1. Details are not described again in this specification.

[0201] Example 3: The first instruction information includes the length of at least one of the time windows.

[0202] For example, it can be assumed that the lengths of the time windows are identical (e.g., predefined or indicated by the first indication information), and accordingly, the first indication information needs to indicate the length of only one time window.

[0203] Example 4: The first instruction information includes an offset.

[0204] For example, the offset includes at least one of the following: an offset between the start position of at least one time window and the start position of the CDRX OnDuration; an offset between the start position of at least one time window and the end position of the CDRX OnDuration; an offset between the start position of at least one time window and the middle position of the CDRX OnDuration; an offset between the start position of any one of at least one time window and the start position of the CDRX OnDuration; an offset between the start position of any one of at least one time window and the end position of the CDRX OnDuration; or an offset between the start position of any one of at least one time window and the middle position of the CDRX OnDuration.

[0205] In a second possible implementation, the time window is predefined.

[0206] Based on this method, optionally, the method (400) further includes: the terminal device determines at least one time window.

[0207] For example, frames with frame_index mode X = 1 or 2, that is, the first two frames out of all X frames, can be predefined as locations where the terminal device can perform measurements during the process of monitoring the wake-up signal, i.e., at least one time window is the first two frames out of all X frames. X is an integer greater than 0, for example, X = 20. "1" and "2" represent the index of the frame, and the index of the frame can alternatively be other values.

[0208] As another example, it may be predefined that the location where the terminal device can perform a measurement during the process of monitoring the wake-up signal is within the CDRX ON period, that is, that at least one time window is the CDRX ON period. Alternatively, the starting location of the CDRX ON period is used as a reference, and a time location of length L (e.g., 20 ms) is the location where the terminal device can perform a measurement during the process of monitoring the wake-up signal, that is, that the starting location of at least one time window is the starting location of the CDRX ON period and length L can be predefined. L is a number greater than 0.

[0209] For information regarding the time window, refer to the description in the first possible embodiment. Details are not described again in this specification.

[0210] Solution 3: A network device sets or pre-defines a time domain resource of a wake-up signal, and a terminal device receives a reference signal on a time domain resource other than the time domain resource of the wake-up signal. In this regard, the time domain resource of the reference signal in step (410) is a time domain resource different from the time domain resource of the wake-up signal, or a time domain resource other than the time domain resource of the wake-up signal. Specifically, when the network device needs to transmit a wake-up signal, the network device transmits the wake-up signal on the time domain resource of the wake-up signal and does not transmit the wake-up signal on a time domain resource other than the time domain resource of the wake-up signal. Correspondingly, the terminal device monitors the wake-up signal on the time domain resource of the wake-up signal and does not monitor the wake-up signal on a different time domain resource. Additionally, when a network device needs to transmit a reference signal (or needs to set a time domain resource of the reference signal), the network device transmits the reference signal on a time domain resource other than the time domain resource of the wake-up signal or sets the time domain resource of the reference signal on a time domain resource other than the time domain resource of the wake-up signal. In response, the terminal device receives the reference signal on a time domain resource other than the time domain resource of the wake-up signal.

[0211] In this solution, the terminal device and the network device align time-domain resource locations for measurement to avoid missing detection of the wake-up signal.

[0212] For example, FIG. 8 is a diagram of solution means 3 applicable to one embodiment of the present application. As illustrated in FIG. 8, it is assumed that a network device sets a time domain resource used to monitor a wake-up signal for a terminal device, and that the terminal device monitors the wake-up signal on the time domain resource of the wake-up signal and does not monitor the wake-up signal on a time domain resource other than the time domain resource of the wake-up signal. When performing a measurement based on a reference signal, the terminal device receives the reference signal used for the measurement on a time domain resource other than the time domain resource of the wake-up signal.

[0213] For example, the time domain resource used to monitor the wake-up signal illustrated in FIG. 8 may be part of all time domain resources used to monitor the wake-up signal. For example, a terminal device monitors the wake-up signal in a duty cycle manner. The time domain resource used to monitor the wake-up signal illustrated in FIG. 8 is a time domain location for periodically monitoring the wake-up signal.

[0214] Based on solution means 3, determining the time domain resource of the reference signal and the time domain resource of the wake-up signal in step (410) may alternatively be replaced by determining the time domain resource of the wake-up signal. After the time domain resource of the wake-up signal is determined, the time domain resource of the reference signal may also be directly determined, that is, the time domain resource of the reference signal is a time domain resource other than the time domain resource of the wake-up signal, or the time domain resource of the reference signal is a time domain resource different from the time domain resource of the wake-up signal. In this case, the "time domain resource of the reference signal" is a location where the reference signal can be received. In other words, the present embodiment of the application does not restrict the transmission of the reference signal at all locations on the "time domain resource of the reference signal" and does not restrict the terminal device to receive the reference signal at all locations. That is, if a network device needs to transmit the reference signal, the network device can transmit the reference signal by using the time domain resource within the "time domain resource of the reference signal"; Alternatively, if the terminal device needs to receive a reference signal, the terminal device may receive the reference signal by using a time domain resource within the "time domain resource of the reference signal".

[0215] In solution 3, the time domain resource of the reference signal may be predefined or set to be a time domain resource other than the time domain resource of the wake-up signal. This is not limited in the present specification. For example, the protocol may define a location where the terminal device performs a measurement other than the time domain resource of the wake-up signal.

[0216] Optionally, the time domain resources of the wake-up signal are discontinuous. That is, the wake-up signal comprises multiple time domain units in the time domain, and at least two of the multiple time domain units are discontinuous. For example, the discontinuous time domain resources of the wake-up signal can be combined with solution means 3. Solution means 3 is used as an example. As illustrated in FIG. 8, the time domain resources of the wake-up signal are discontinuous.

[0217] Additionally, optionally, the interval between any two adjacent consecutive time domain resources is 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 within each group of time domain units are consecutive, and the interval between two adjacent groups of time domain units within the M groups of time domain units is the same or different.

[0218] In a possible embodiment, the time domain resource of the wake-up signal is periodic. In this regard, the terminal device can periodically monitor the wake-up signal.

[0219] Additionally, optionally, the method (400) further comprises: the terminal device transmits second instruction information to the network device, wherein the second instruction information indicates the expected time domain resource of the terminal device, i.e., the time domain resource expected by the terminal device for the transmission of a reference signal and indicated by the second instruction information. In this regard, the terminal device may report the expected measurement time to the network device.

[0220] Solution 2 is used as an example. The network device may determine at least one time window based on the measurement time domain resources expected by the terminal device in the second instruction information. In this way, the set at least one time window can better satisfy the requirements of the terminal device.

[0221] The foregoing describes the means of resolving the time domain resources of the wake-up signal and the time domain resources of the reference signal. It should be noted that regarding the time domain resources of other signals monitored (or received) by the wake-up circuit, the method (400) also refers to the relevant design of the time domain resources of the wake-up signal.

[0222] For example, the method (400) may also be modified as follows: In step (410), the terminal device determines the time domain resource of the reference signal and the time domain resource of the first type signal. In step (420), the terminal device receives the reference signal on part or all of the time domain resource of the reference signal. In step (430), the terminal device monitors (or receives) the first type signal on the time domain resource of the first type signal. The first type signal includes a wake-up signal and / or a synchronization signal (e.g., LP-SS).

[0223] In another example, the method (400) may also be modified as follows: In step (410), the terminal device determines the time domain resource of the type 2 signal and the time domain resource of the type 1 signal. In step (420), the terminal device receives the type 2 signal on part or all of the time domain resource of the type 2 signal. In step (430), the terminal device monitors (or receives) the type 1 signal on the time domain resource of the type 1 signal. The type 1 signal includes a wake-up signal and / or a synchronization signal (e.g., LP-SS), and the type 2 signal includes a reference signal.

[0224] Type 1 signals and Type 2 signals are described in detail below.

[0225] Optionally, the terminal device transmits capability information to a network device, wherein the capability information indicates whether the Type 1 signal and the Type 2 signal can be received simultaneously (or whether the simultaneous reception of the Type 1 signal and the Type 2 signal can be supported). The ability of the terminal device to transmit capability information to the network device may be used in combination with the method (400) or independently. This is not limited in the specification. For example, when used in combination, the indication information may indicate that the terminal device cannot receive the Type 1 signal and the Type 2 signal simultaneously. In this way, if the terminal device cannot receive the Type 1 signal and the Type 2 signal simultaneously, the terminal device may receive a reference signal and monitor a wake-up signal in the manner described in the method (400).

[0226] Optionally, the terminal device includes a first module and a second module. The indication information indicating whether the first type signal and the second type signal can be received simultaneously may alternatively be replaced as follows: the indication information indicates whether the first module (e.g., a wake-up circuit) and the second module (e.g., a main circuit) can receive the signals simultaneously. Refer to the foregoing description for the first module and the second module. Details are not described again in this specification. The wake-up circuit and the main circuit are described below as examples.

[0227] Optionally, OOK modulation is used for the Type 1 signal, and non-OOK modulation is used for the Type 2 signal. For example, the modulation scheme for the Type 2 signal is OFDM or DFT-s-OFDM.

[0228] Optionally, the first type signal includes a wake-up signal and / or a synchronization signal (e.g., LP-SS).

[0229] Optionally, the Type 2 signal is a signal different from the wake-up signal and the synchronization signal. The Type 2 signal may represent various downlink signals, for example, in an NR system. For example, the Type 1 signal includes one or more of an SSB, PDCCH, physical downlink shared channel (PDSCH), CSI-RS, phase tracking reference signal (PTRS), positioning reference signal (PRS), and demodulation reference signal (DMRS).

[0230] Optionally, capability information is per band or capability information is associated with a band; capability information is per band combination or capability information is associated with a band combination. In this regard, different bands or band combinations may have respective capability information, and capability information may be reported for different bands or band combinations. Band combinations may alternatively be replaced by other descriptions, e.g., band groups. The designation does not limit the scope of protection of the embodiments of this application. Descriptions below are provided with reference to two cases.

[0231] In the first possible case, the capability information is per band combination, or the capability information is associated with the band combination.

[0232] For example, capability information and bandwidth combinations may exist in the form of a table, function, text, or string, and may be stored or transmitted, for example. Table 1 is an example of presenting capability information and bandwidth combinations in the form of a table.

[0233] Band combination Ability Information Band #1 and Band #2 Type 1 signal and Type 2 signal can be received simultaneously. Band #3 and Band #4 Type 1 signal and Type 2 signal cannot be received simultaneously.

[0234] Table 1 is used as an example. When the wake-up circuit and main circuit of a terminal device operate in band #1 and band #2, respectively, for example, when the wake-up circuit operates in band #1 and the main circuit operates in band #2, or for another example, when the wake-up circuit operates in band #2 and the main circuit operates in band #1, the terminal device can receive the Type 1 signal and the Type 2 signal simultaneously; that is, the terminal device can receive signals simultaneously through the main circuit and the wake-up circuit. When the wake-up circuit and main circuit of a terminal device operate in band #3 and band #4, respectively, for example, when the wake-up circuit operates in band #3 and the main circuit operates in band #4, or for another example, when the wake-up circuit operates in band #4 and the main circuit operates in band #1, the terminal device cannot receive the Type 1 signal and the Type 2 signal simultaneously; that is, the terminal device cannot receive signals simultaneously through the main circuit and the wake-up circuit.

[0235] That the main circuit operates in Band 1 indicates that the frequency at which a signal is received through the main circuit is Band 1. Similarly, that the wake-up circuit operates in Band 2 indicates that the frequency at which a signal is received through the wake-up circuit is Band 2. This is not explained below.

[0236] It may be understood that Table 1 is an example for illustrative purposes. This is not limited to the present specification. For example, more band combinations may be included. For other examples, band combinations may include more bands.

[0237] In this case, the capability information reported by the terminal device may be capability information for a single band combination or capability information for some band combinations. Table 1 is used as an example. The terminal device may report capability information associated with a band combination of Band #1 and Band #2 and / or the terminal device may report capability information associated with a band combination of Band #3 and Band #4. Additionally, the reported capability information may include capability information and information about the associated band combination (e.g., an identifier of the associated band combination); or may include capability information directly. In this case, the network side (e.g., a network device) may be presumed by default to know which band combination is associated with the capability information.

[0238] In a second possible case, the capability information is band-specific or the capability information is band-associated. In this case, the main circuit and the wake-up circuit may be predefined or assumed by default to operate in the same band.

[0239] For example, capability information and bandwidths may exist in the form of tables, functions, text, or strings, and may be stored or transmitted, for example. Table 2 is an example of presenting capability information and bandwidths in the form of a table.

[0240] treason Ability Information Band #1 Type 1 signal and Type 2 signal can be received simultaneously. Band #2 Type 1 signal and Type 2 signal can be received simultaneously. Band #3 Type 1 signals and Type 2 signals cannot be received simultaneously.

[0241] Table 2 is used as an example. When the terminal device operates in Band #1 or Band #2, that is, when the frequency of the signal is in Band #1 or Band #2, the terminal device can receive the Type 1 signal and the Type 2 signal simultaneously, that is, the terminal device can receive the signals simultaneously through the main circuit and the wake-up circuit. When the terminal device operates in Band #3, that is, when the frequency of the signal is in Band #3, the terminal device cannot receive the Type 1 signal and the Type 2 signal simultaneously, that is, the terminal device cannot receive the signals simultaneously through the main circuit and the wake-up circuit.

[0242] It may be understood that Table 2 is an example for illustrative purposes. This is not limited to the specification. For example, more bands may be included. As another example, bands in which the Type 1 signal and the Type 2 signal can be received simultaneously may be listed together, and bands in which the Type 1 signal and the Type 2 signal cannot be received simultaneously may be listed together.

[0243] In this case, the capability information reported by the terminal device may be capability information of a band (e.g., a band supported by the terminal device) or capability information of a sub-band (e.g., a sub-band supported by the terminal device). Table 2 is used as an example. The terminal device may report capability information associated with at least one of band #1, band #2, or band #3. Additionally, the reported capability information may include capability information and information about the associated band (e.g., an identifier of the associated band); may include capability information directly, in which case the network side (e.g., a network device) may be presumed by default to know which band is associated with the capability information; or may include information about the band directly, in which case the network side may be presumed by default to know the capability information of the band.

[0244] In the foregoing, it may be understood that bands and band combinations have been described by example. This is not limited to the present specification. For example, a band may also be replaced with other frequency domain units.

[0245] In embodiments of the present application, it may be understood that "receiving" may alternatively be replaced with "detecting," "reading," or "monitoring." For example, "receiving a reference signal" may alternatively be replaced with "detecting a reference signal," "reading a reference signal," or "monitoring a reference signal."

[0246] In some of the embodiments described above, it may be further understood that the main circuit and the wake-up circuit are primarily used as examples for illustrative purposes. The present application is not limited thereto. For example, "wake-up circuit" may alternatively be replaced with "first module," "wake-up link," "in a first state," or "in a first mode." For example, "the terminal device receives a signal through the wake-up circuit" may alternatively 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." "Main circuit" may alternatively be replaced with "second module," "main link," "in a second state," or "in a second mode." For example, "the terminal device receives a signal through the main circuit" can be alternatively replaced with "the terminal device receives a signal through the second module, or the terminal device receives a signal on the main link."

[0247] In some of the embodiments described above, it may be more understood that "transmission" is referred to. Unless otherwise specified, transmission includes receiving and / or transmitting. For example, performing the transmission of a signal may include receiving the signal and / or transmitting the signal.

[0248] In the embodiments of the present application, it may be further understood that the interaction between the terminal device and the network device is used primarily as an example for illustrative purposes. The present application is not limited thereto. The terminal device may be replaced by a receiving device, and the receiving device may be a terminal device or a network device. The network device may be replaced by a transmitting device, and the transmitting device may be a terminal device or a network device. For example, the "terminal device" may be replaced by a "first terminal device," and the "network device" may be replaced by a "second terminal device."

[0249] In some of the embodiments described above, it may be further understood that signal transmission is referred to as a plurality of times. For example, A transmits a signal to B. Transmitting a signal by A to B may include A transmitting the signal directly to B, or A transmitting the signal to B through another device or network element. This is not limited in this specification.

[0250] In some of the embodiments described above, the prior definition is mentioned multiple times, which may be understood to refer to a prior definition in a standard protocol or to refer to prior consultation or prior negotiation between devices.

[0251] It may be further understood that in the embodiments of the present application, some optional features may be independent of other features in some scenarios or may be combined with other features in some scenarios. This is not limited to this.

[0252] In the aforementioned method embodiments, it may be further understood that the method and operation implemented by the terminal device may alternatively be implemented by a component of the terminal device (e.g., a chip or circuit). Additionally, the method and operation implemented by the network device may alternatively be implemented by a component of the network device (e.g., a chip or circuit). This is not limited to this.

[0253] The foregoing details describe the methods provided in the embodiments of the present application with reference to FIGS. 4 through 8. Hereinafter, the apparatuses provided in the embodiments of the present application are described in detail with reference to FIGS. 9 through 11. It should be understood that the description of the apparatus embodiments corresponds to the description of the method embodiments. Accordingly, for details not described in detail, reference is made to the method embodiments described above. For the sake of brevity, details are not described again in this specification.

[0254] For example, FIG. 9 is a drawing of a communication device (900) according to one embodiment of the present application. The device (900) includes a transceiver unit (910) and a processing unit (920). The transceiver unit (910) may be configured to implement a corresponding communication function.
