Description

Communication methods and communication devices

[0001] This application claims priority to Chinese Patent Application No. 202410577324.5, filed on May 10, 2024, entitled "Communication Method and Communication Device", the entire contents of which are incorporated herein by reference. Technical Field

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

[0003] The terminal device can receive a wake-up signal via a separate low-power circuit, such as a wake-up radio (WUR), while the main receiver can be in sleep mode. When the terminal device detects the wake-up signal via the WUR, it triggers the main receiver to wake up. After the main receiver wakes up, the terminal device can receive data, etc. The network device can indicate the time-domain resources for the wake-up signal to the terminal device, allowing the terminal to receive the wake-up signal based on those resources. Therefore, how to indicate the time-domain resources for the wake-up signal is a question worth considering. Summary of the Invention

[0004] This application provides a communication method and a communication device that can flexibly indicate the time-domain resources of a wake-up signal.

[0005] Firstly, a communication method is provided. This method can be applied to the terminal side; that is, it can be executed by the terminal device or by components of the terminal device (such as a chip, chip system, circuit, or communication module). This application does not limit the scope of the method. The following description mainly uses a terminal device as an example.

[0006] The method may include: receiving configuration information, the configuration information indicating a first pattern and a second pattern, the first pattern indicating a first time unit among X first time units that can be used to transmit a wake-up signal, the second pattern indicating a second time unit among N second time units that applies the first pattern, each of the N second time units including X first time units, where X and N are integers greater than or equal to 1; and monitoring the wake-up signal based on the configuration information.

[0007] Based on the above technical solution, network devices can indicate the time-domain resources for wake-up signals to terminal devices through a first pattern and a second pattern. Specifically, the first pattern indicates to the terminal device whether each of one or more first time units can be used to transmit wake-up signals; that is, the terminal device can use the first pattern to identify the first time units that can be used to transmit wake-up signals from one or more first time units. Furthermore, a second time unit includes X first time units. The second pattern indicates to the terminal device whether each of one or more second time units can use the first pattern; that is, the terminal device can use the second pattern to identify the second time units that apply the first pattern, and thus identify all the first time units that can be used to transmit wake-up signals from the one or more second time units. This method not only allows for flexible indication of the time-domain resources for wake-up signals, but also, by unifying with the RateMatchPattern method, reduces the number of RateMatchPattern sets used by other terminal devices.

[0008] In conjunction with the first aspect, in some implementations of the first aspect, the configuration information includes a first bitmap; the first pattern indicates the first time unit among X first time units that can be used to transmit a wake-up signal, including: the first bitmap indicates the first time unit among X first time units that can be used to transmit a wake-up signal.

[0009] Based on the above technical solution, a bitmap can be used to indicate whether each of the first time units in one or more first time units can be used to transmit a wake-up signal, that is, the first time unit in one or more first time units that can be used to transmit a wake-up signal. The method is simple and easy to implement.

[0010] In conjunction with the first aspect, in some implementations of the first aspect, the configuration information includes a second bitmap, the second pattern indicating the second time units in N second time units where the first pattern is applied, including: the second bitmap indicating the second time units in N second time units where the first pattern is applied.

[0011] Based on the above technical solution, a bitmap can be used to indicate whether each second time unit in one or more second time units uses the first pattern. That is, the second time units in one or more second time units that use the first pattern can greatly save signaling overhead compared to using the first pattern to indicate the first time units in each second time unit that can be used to transmit wake-up signals.

[0012] In conjunction with the first aspect, in some implementations of the first aspect, the configuration information also indicates a first time period; based on the configuration information, monitoring the wake-up signal includes: monitoring the wake-up signal in a first time unit within the first time period that can be used to transmit the wake-up signal.

[0013] In conjunction with the first aspect, in some implementations of the first aspect, the starting positions of the N second time units are associated with the starting position of the first time period, or the starting positions of the N second time units are associated with the system time.

[0014] Based on the above technical solution, the starting positions of the N second time units are associated with the system time or the starting position of the first time period. In this way, the terminal device can determine the starting positions of the N second time units based on the starting position of the system time or the first time period, and then determine the positions of the N second time units, and then determine the position of the time domain resources of the wake-up signal.

[0015] In conjunction with the first aspect, in some implementations of the first aspect, the system time is the system frame number.

[0016] In conjunction with the first aspect, in some implementations of the first aspect, the period of the first time segment is an integer multiple of N.

[0017] In conjunction with the first aspect, in some implementations of the first aspect, the configuration information also indicates at least one of the following: the length of the first time period, the offset of the first time period, the number of first time periods within a period, and the period of the first time period.

[0018] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: receiving indication information indicating information about the synchronization signal block (SSB) associated with the wake-up signal, wherein the number of SSBs associated with the wake-up signal is less than or equal to the number of SSBs actually transmitted in an SSB set.

[0019] Based on the above technical solution, considering that the number of transmit beams for the wake-up signal may differ from the number of transmit beams for the SSB, the network device can indicate the SSB associated with the wake-up signal to the terminal device. This allows for the transmission of the wake-up signal and SSB with different numbers of transmit beams depending on the actual communication situation. Furthermore, the terminal device can determine the SSB associated with the wake-up signal based on the network device's instruction, enabling it to determine the best or better beam direction and thus the reception parameters for the wake-up signal (such as beam direction and timing). In addition, the number of transmit beams for the wake-up signal may be less than or equal to the number of transmit beams for the SSB, which reduces interference at the cell edge and minimizes the resource overhead of the wake-up signal.

[0020] In conjunction with the first aspect, in some implementations of the first aspect, the indication information indicates information about the SSB associated with the wake-up signal, including: the indication information indicates an SSB associated with the wake-up signal in a set of SSBs.

[0021] In conjunction with the first aspect, in some implementations of the first aspect, the SSB associated with the wake-up signal and the wake-up signal have a quasi-co-addressable QCL relationship.

[0022] In conjunction with the first aspect, in some implementations of the first aspect, the indication information is a third bitmap, and the number of bits in the third bitmap is the maximum number of SSBs in an SSB set or the number of SSBs actually transmitted in an SSB set.

[0023] Based on the above technical solution, when the number of bits in the third bitmap is the maximum number of SSBs in an SSB set, the number of bits contained in the third bitmap is fixed, which is simple and easy to implement. When the number of bits in the third bitmap is the number of SSBs actually transmitted in an SSB set, the number of bits contained in the third bitmap can be reduced, thereby reducing the configured signaling overhead.

[0024] In conjunction with the first aspect, in some implementations of the first aspect, monitoring the wake-up signal based on configuration information includes: monitoring the wake-up signal in a first time unit that can be used to transmit the wake-up signal within a first time period; the bit value in the third bitmap is a first value representing the SSB associated with the wake-up signal; the first time period includes K groups of monitoring opportunities MO; each group of MO includes T MOs; T represents the number of bits in the third bitmap with the first value; and K is an integer greater than or equal to 1.

[0025] In conjunction with the first aspect, in some implementations of the first aspect, the wake-up signals transmitted on the T MOs in each group of MOs carry the same information.

[0026] In conjunction with the first aspect, in some implementations of the first aspect, there is a one-to-one correspondence between T MOs and T SSBs, and the wake-up signals transmitted on the T MOs have a QCL relationship with the T SSBs.

[0082] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0083] Before introducing the scheme of this application, the following points should be noted.

[0084] (1) In this application, "instruction" can include direct instruction, indirect instruction, explicit instruction, implicit instruction, etc. When describing an instruction information as indicating A, it can be understood that the instruction information carries A, carries the identifier of A, carries B which is associated with A, carries the identifier of B which is associated with A, etc. In other words, if the receiving side of an instruction information can determine A based on the instruction information, it can be described as the instruction information indicating A, and the specific method of determination is not limited. When it is understood that the instruction information carries A, "instruction" can be replaced with "includes". In this case, a statement such as "send / receive instruction information, the instruction information indicates A" can be replaced with "send / receive A".

[0085] In this application, the information indicated by the instruction information is called the information to be instructed. In specific implementations, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is a relationship between the other information and the information to be instructed. It can also indicate only a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing instruction overhead to some extent. Furthermore, the information to be instructed can be sent as a whole or divided into multiple sub-information pieces, and the sending period and / or timing of these sub-information pieces can be the same or different.

[0086] (2) In this application, the expression " / " is used to indicate that the objects 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 before and after are in a relationship of either "and" or "or"; for example, A and / or B can mean the following: 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 similar expressions are used to indicate any combination of the listed items; for example, at least one of A, B and / or C can mean the following: 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.

[0087] (3) In this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include direct transmission via the air interface or indirect transmission by other units or modules via the air interface. "Receive information from YY" can be understood as the source of the information being YY, which may include direct reception from YY via the air interface or indirect reception from YY by other units or modules via the air interface. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface. In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via a bus, wiring, or interface.

[0088] (4) In the various embodiments of this application, unless otherwise specified or in case of logical conflict, the terms and / or descriptions of different embodiments are consistent and can be referenced by each other. The technical features of different embodiments can be combined to form new embodiments according to their inherent logical relationship.

[0089] (5) In this application, "first," "second," and "#1," "#2," and "#A" are merely for descriptive convenience and are used to distinguish objects, and are not intended to limit the scope of the embodiments of this application. They are not used to describe the order or sequence of features. It should be understood that such described objects can be interchanged where appropriate in order to describe solutions other than those in the embodiments of this application.

[0090] (6) In this application, "predefined" can mean a standard protocol predefined, or it can mean a pre-agreed or pre-negotiated agreement between devices. Here, "protocol" can refer to a standard protocol in the field of communications, for example, it may include fourth-generation (4G) protocols. th Generation 4G network, fifth generation (5G) network th 5G network protocol, New Radio (NR) protocol, 5.5G network protocol, sixth generation (6G) network protocol th This application does not limit the scope of network protocols (generation, 6G) and related protocols applied in future communication systems.

[0091] (7) In this application, the words “exemplary,” “for example,” etc., are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as an “example” in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the word “example” is intended to present the concept in a concrete manner. In the embodiments of this application, “of,” “corresponding, relevant,” and “corresponding” may sometimes be used interchangeably, and it should be noted that their intended meanings are consistent unless their distinction is emphasized.

A base station can broadly encompass, or be replaced by, various names including: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, access point, transmitting and receiving point (TRP), transmitter point, master station, auxiliary station, motor slide retainer (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, micro base station, relay node, donor node, or a combination thereof. A base station can also refer to a communication module, modem, or chip installed within the aforementioned equipment or apparatus. Base stations can also be mobile switching centers, devices that perform base station functions in D2D, V2X, and M2M communications, network-side devices in 6G networks, and devices that perform base station functions in future communication systems. Base stations can support networks with the same or different access technologies. The embodiments of this application do not limit the specific technologies or device forms used in the network equipment.

[0101] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move depending on the location of the mobile base station. In other examples, a helicopter or drone can be configured as a device to communicate with another base station.

[0102] In some deployments, the network devices mentioned in the embodiments of this application may be devices including CU, or DU, or devices including CU and DU, or devices with control plane CU nodes (central unit-control plane (CU-CP)) and user plane CU nodes (central unit-user plane (CU-UP)) and DU nodes.

[0103] In some deployments, multiple RAN nodes collaborate to assist terminal devices in achieving wireless access, with different RAN nodes each implementing some of the base station's functions. For example, RAN nodes can be CUs, DUs, CU-CPs, CU-UPs, or radio units (RUs). CUs and DUs can be configured separately or included in the same network element, such as a BBU. RUs can be included in radio equipment or radio units, such as RRUs, AAUs, or RRHs.

[0104] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, a radio access network can also be an open radio access network (O-RAN) architecture. In an O-RAN system, CU can also be called an open CU (openCU, O-CU), DU can also be called an open DU (open DU, O-DU), CU-CP can also be called an open CU-CP (open CU-CP, O-CU-CP), CU-UP can also be called an open CU-UP (open CU-UP, O-CU-UP), and RU can also be called an open RU (openRU, O-RU). Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0105] In this embodiment, the device for implementing the functions of a network device can be a network device itself, or a device capable of supporting the network device in implementing those functions, such as a chip system, chip, circuit, or communication module (i.e., a communication module that performs communication functions). This device can be installed within the network device. In this embodiment, the chip system can be composed of chips, or it can include chips and other discrete devices. Furthermore, the device can be configured with program instructions for performing corresponding communication functions. This embodiment only uses a network device as an example to illustrate the device for implementing the functions of a network device, and does not limit the solution of this embodiment.

[0106] Network devices and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. This application does not limit the scenario in which the network devices and terminal devices are located.

[0107] The communication system applicable to the embodiments of this application is briefly described below with reference to Figure 1.

[0108] Referring to Figure 1, as an example, Figure 1 is a schematic diagram of a wireless communication system applicable to an embodiment of this application. As shown in Figure 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 higher) wireless access network or a traditional (e.g., 5G, 4G, 3G, or 2G) wireless 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 wireless access network 100. Network elements in the wireless communication system are connected through interfaces (e.g., NG, Xn) or over-the-air interfaces.

[0109] When network devices and terminal devices communicate, the network device can manage one or more cells, and a cell can include at least one terminal device. A cell can be understood as an area within the wireless signal coverage range of the network device.

[0110] Figure 1 is just a schematic diagram. The wireless communication system may also include other devices, such as core network devices, wireless relay devices and / or wireless backhaul devices, which are not shown in Figure 1.

[0111] To facilitate understanding of the embodiments of this application, the terms used in this application will be briefly explained.

[0112] 1. Wake-up circuit: Also known as a wake-up receiver / radio (WUR), low-power wake-up receiver (LP-WUR), or wake-up module, it can be understood as a single, low-power small circuit, such as the circuit used by a terminal device in the idle state. This low-power small circuit can be implemented using a simple, single small circuit or chip with low power consumption. It is understood that the term "wake-up circuit" is merely a designation for differentiation, and its specific naming does not limit the scope of protection of this application. For example, without loss of generality, a wake-up circuit can also be described as a first circuit (or first module). The following description will uniformly refer to it as a wake-up circuit.

[0113] The signal received by the terminal device through the wake-up circuit can be referred to as being transmitted on the wake-up link. The wake-up link represents a connection relationship between the terminal device and the network device; it is a logical concept, not a physical entity. It is understood that the term "wake-up link" is merely a designation for differentiation, and its specific naming does not limit the scope of protection of this application. For example, without loss of generality, a wake-up link can also be described as a first link. Hereinafter, it will be uniformly referred to as a wake-up link.

[0114] The signal received by the terminal device using the wake-up circuit can be called a wake-up signal (WUS) or a low-power wake-up signal (LP-WUS). It is understood that the term "wake-up signal" is merely a designation for differentiation, and its specific name does not limit the scope of protection of this application. For example, without loss of generality, a wake-up signal can also be called a signal. The following description will consistently use "wake-up signal".

[0115] 2. Main Circuit: Also known as the main receiver (MR) or main module, it can be understood as the circuit used by the terminal device during normal data transmission, or the circuit used by the terminal device during data transmission in a connected state. The terminal device consumes a significant amount of power when transmitting data through the main circuit. It is understood that the term "main circuit" is merely a designation for differentiation and does not limit the scope of protection of this application. For example, without loss of generality, the main circuit can also be described as a second circuit (or second module). The following text will uniformly describe it as the main circuit.

[0116] Signals received by a terminal device through the main circuit can be referred to as being transmitted on the main link. The main link represents a connection between the terminal device and the network device; it is a logical concept, not a physical entity. It is understood that the term "main link" is merely a designation for distinction, and its specific naming does not limit the scope of protection of this application. For example, without loss of generality, the main link can also be described as a second link. The following text will uniformly refer to it as the main link.

[0117] In the following text, for the sake of distinction, the signals transmitted by the main circuit of the terminal device will be referred to as data signals.

[0118] Referring to Figure 2, as an example, Figure 2 is a schematic diagram of the main circuit and the wake-up circuit.

[0119] As shown in Figure 2, the terminal device can receive (or detect, or monitor) a wake-up signal through a wake-up circuit, and can receive data signals through the main circuit. Assume the terminal device receives the wake-up signal through the wake-up circuit. If the terminal device does not detect the wake-up signal, it continues to receive it through the wake-up circuit, and the main circuit can be in a closed state (or sleep state). If the terminal device detects the wake-up signal, it triggers the main circuit to wake up, that is, it puts the main circuit into / switches to an open state (or working state, or active state). After the main circuit is turned on, the terminal device can transmit data signals through the main circuit.

[0120] 3. On-Off-Key (OOK) Modulation: This modulates information based on whether a signal is transmitted or not. The corresponding wake-up circuit can use envelope detection to receive the signal. OOK modulation technology can be demodulated using a low-complexity receiver, thus achieving the low-power goal of the wake-up circuit. To ensure power efficiency, the wake-up signal can use OOK modulation. It is understood that other modulation methods can also be used for the wake-up signal; there are no restrictions on this.

[0121] When a signal is modulated using OOK, each bit (i.e., the encoded bit) corresponds to a symbol. Equivalently, a symbol can also be called a chip, or any other name, which is not limited here.

[0122] For example, when a bit is "1", a signal is transmitted within the symbol length (i.e., the signal transmission power within that symbol length is not 0); when a bit is "0", no signal is transmitted within the symbol length (i.e., the signal transmission power within that symbol length is 0). Alternatively, it can be understood that in OOK modulation, transmitting energy represents "1", and not transmitting energy represents "0".

[0123] For example, when the bit is "0", a signal is transmitted within the symbol length (i.e., the signal transmission power within that symbol length is not 0); when the bit is "1", no signal is transmitted within the symbol length (i.e., the signal transmission power within that symbol length is 0). Alternatively, it can be understood that in OOK modulation, transmitting energy represents "0", and not transmitting energy represents "1".

[0124] For ease of description, the following text will primarily use the example of a signal being emitted within the symbol length when the bit is "1" and no signal being emitted within the symbol length when the bit is "0" as an example for illustration.

[0125] Furthermore, for ease of description, if a symbol emits a signal, it is denoted as an ON symbol; if a symbol emits no signal, it is denoted as an OFF symbol. Taking the example that when a bit is "1", a signal is emitted within the length of the symbol; and when a bit is "0", no signal is emitted within the length of the symbol, the ON symbol represents an information bit of "1", and the OFF symbol represents an information bit of "0". The ON symbol can also be called an ON signal, and the OFF symbol can also be called an OFF signal; for consistency, the ON and OFF symbols will be used in the following descriptions.

[0126] Wherein, the signal amplitude of the ON symbol is greater than or equal to a first threshold, and the signal amplitude of the OFF symbol is less than or equal to a second threshold; or, in other words, the signal amplitude of the ON symbol is greater than the signal amplitude of the OFF symbol; or, within a preset time period, the signal amplitude of the ON symbol is greater than the signal amplitude of the OFF symbol; or, within a preset time period, the signal power of the ON symbol is greater than the signal power of the OFF symbol; or, within a preset time period, the signal power of the ON symbol is greater than or equal to the first threshold, and the signal power of the OFF symbol is less than or equal to the second threshold; or, within a preset time period, the signal power of the ON symbol is greater than or equal to the first threshold, and the signal power of the OFF symbol is less than or equal to the second threshold; or, within a preset time period, the signal power of the ON symbol is greater than or equal to the first threshold, and the signal amplitude of the OFF symbol is less than or equal to the second threshold. The signal power of the FF symbol is less than or equal to the second threshold; or, the signal level of the ON symbol is greater than the signal level of the OFF symbol; or, within a preset time period, the signal level of the ON symbol is greater than the signal level of the OFF symbol; or, the signal level of the ON symbol is greater than or equal to the first threshold, and the signal level of the OFF symbol is less than or equal to the second threshold; or, within a preset time period, the signal level of the ON symbol is greater than or equal to the first threshold, and the signal level of the OFF symbol is less than or equal to the second threshold; or, the ON symbol indicates (or corresponds to, or represents) the first bit value, and the OFF symbol indicates (or corresponds to, or represents) the second bit value. Wherein, the first bit value and the second bit value are different. For example, the first bit value is "1", and the second bit value is "0".

[0127] Furthermore, the OOK symbol mentioned below refers to a symbol obtained by OOK modulation. An OOK symbol can be either an ON symbol or an OFF symbol. For example, if the information bit is "1", the OOK symbol obtained by OOK modulation is an ON symbol; if the information bit is "0", the OOK symbol obtained by OOK modulation is an OFF symbol. The OOK symbol can also be called an OOK signal; for consistency, it will be described as an OOK symbol below.

[0128] Referring to Figure 3, as an example, Figure 3 is a waveform diagram of a signal using OOK modulation.

[0129] As an example, suppose that when the bit is "1", a signal is transmitted within the length of the OOK symbol; when the bit is "0", no signal is transmitted within the length of the OOK symbol. Therefore, the waveform shown in Figure 3 can represent the four bits "0100", that is, the first is the OFF symbol, the second is the ON symbol, and the third and fourth are both OFF symbols. As shown in Figure 3, communication systems generally use a certain frequency to transmit, and the transmitted signal needs to be modulated onto the carrier wave. At the receiving end, the receiver detects the envelope (or energy) of the received signal to determine whether the OOK symbol corresponds to a bit "0" or a bit "1", thereby completing demodulation.

[0130] After a signal passes through a channel, it may be distorted due to factors such as channel conditions. Therefore, to determine whether the signal corresponds to a bit "0" or a bit "1", the receiver can compare the received signal level with a threshold. For example, if the received signal level is greater than the threshold, it means the signal corresponds to a bit "1"; if the received signal level is less than the threshold, it means the signal corresponds to a bit "0". However, setting the threshold is difficult. For instance, an inappropriate threshold selection may lead to demodulation errors. To solve this problem, one possible approach is to use Manchester encoding.

[0131] Manchester encoding is a biphase encoding method that uses high-low level switching to represent bits "0" or "1". For example, Manchester encoding can encode a raw bit "0" as bit "10" and a raw bit "1" as bit "01". To distinguish them, the encoded bits, such as bits "10" and "01", are called encoded bits. When transmitting a signal, the transmitter can use two OOK symbols to send one bit of original information. If the raw bit "0" is encoded as bit "10" and the raw bit "1" is encoded as bit "01", then the raw bit "0" corresponds to one ON symbol followed by one OFF symbol, and the raw bit "1" corresponds to one OFF symbol followed by one ON symbol. When demodulating the Manchester-encoded signal, the receiver can compare the relative magnitude of the signal power (or signal amplitude) within two adjacent OOK symbols. If the signal power (or signal amplitude) in the preceding OOK symbol is greater than that in the following OOK symbol, the received information bit is considered "0"; otherwise, it is considered "1". In this way, we can avoid using an absolute threshold to make a decision.

[0132] It is understood that the above example of encoding a raw bit "0" as bit "10" and a raw bit "1" as bit "01" is for illustrative purposes only and is not intended to be limiting. For example, a raw bit "0" can be encoded as bit "01" and a raw bit "1" can be encoded as bit "10".

[0133] As an example, a signal can be generated based on an orthogonal frequency division multiplexing (OFDM) transmitter, that is, an OFDM transmitter can be used to modulate the signal.

[0134] One possible approach is to transmit an OOK symbol within the length of an OFDM symbol, or in other words, an OOK symbol occupies one OFDM symbol. For example, to transmit an ON symbol within the length of an OOK symbol, the transmitter can send a specific signal whose contour within the OOK symbol length is as square as possible; to transmit an OFF symbol within the length of an OOK symbol, the transmitter can turn off the signal for the length of an OOK symbol.

[0135] 4. Time-domain monitoring position of wake-up signal: For wake-up signal, its time-domain monitoring position can be defined, such as wake-up signal timing or low-power wake-up signal timing (LP-WUSoccasion, LO).

[0136] A single Loop (LO) may include one or more monitoring occasions (MOs), also known as wake-up signal MOs (LP-WUS MOs). An MO refers to the basic time unit when the wake-up circuit is operating. A wake-up signal may occupy one or more MOs. MOs and OFDM symbols are similar concepts; that is, an MO is a unit (e.g., the smallest unit) of time-domain resource scheduling, meaning a time unit (or time-domain unit) can be one MO. For example, an MO may include one or more OOK symbols, or an MO may include one or more OFDM symbols, etc.

[0137] As an example, an LO includes T*K MOs, where T represents the number of beams and K represents the number of MOs per beam.

[0138] In a protocol, beaming can be represented as a spatial domain filter, spatial parameter, spatial domain setting, spatial setting, quasi-co-location (QCL) information, QCL assumption, QCL indication, etc. Beaming can be indicated by transmission configuration indicator (TCI) state parameters (TCI-state or TCIstate) or by spatial relation parameters. Therefore, in this application, beaming can be replaced by spatial domain filter, spatial filter, spatial parameter, spatial parameter, spatial setting, spatial setting, QCL information, QCL assumption, QCL indication, TCI-state, spatial relation, etc. These terms are also equivalent to each other. Beaming can also be replaced by other beaming terms, which are not limited in this application.

[0139] 5. Rate matching: This refers to the network device configuring or indicating certain time-frequency resources (denoted as time-frequency resource #A) to the terminal device. If the physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) resources scheduled by the terminal device overlap with time-frequency resource #A, then time-frequency resource #A will not be used for PDSCH / PUSCH transmission. In other words, time-frequency resource #A will be "yielded". These "yielded" resources (i.e., time-frequency resource #A) will not be used for the scheduled PDSCH / PUSCH transmission, but will be used for other signal transmissions.

[0140] Currently, network devices can be configured with a maximum of two RateMatchPatternGroups, each containing eight RateMatchPatterns. Each bandwidth part (BWP) or cell can be configured with a maximum of four RateMatchPatterns. Therefore, for a given terminal device, at any given time, a maximum of four RateMatchPatterns are available.

[0141] When the wake-up signal resources share the same frequency domain resources as other NR signals, the wake-up signal and other NR signals are time-division multiplexed (TDM). In this case, the wake-up signal resources are unavailable to terminal devices receiving or transmitting other NR signals (such as PDSCH / PUSCH). Therefore, rate matching can be used to indicate the locations of these unavailable resources to these terminal devices. The wake-up signal resources refer to the resources available for transmitting the wake-up signal. In other words, if a network device needs to send a wake-up signal, it can use some or all of the wake-up signal resources to send the wake-up signal; if there is no service demand, the network device may not send a wake-up signal, that is, it may not use the wake-up signal resources to send the wake-up signal.

[0142] To avoid the resource location of the wake-up signal, terminal devices receiving or transmitting other NR signals (such as PDSCH / PUSCH) may use multiple rateMatchPattern combinations to indicate the resource location of the wake-up signal. However, as mentioned earlier, for a given terminal device, at any given time, there are a maximum of 4 available rateMatchPatterns (or 4 sets). If multiple rateMatchPattern combinations are used to indicate the resource location of the wake-up signal, then for a given terminal device, the number of available rateMatchPatterns for indicating other occupied resources will be less than 3, resulting in a waste of rateMatchPattern sets.

[0143] In view of this, this application proposes to minimize the use of rateMatchPattern sets on other terminal devices by designing the indication method of wake-up signal resources.

[0144] The methods provided by the embodiments of this application will be described in detail below with reference to the accompanying drawings. The embodiments provided by this application can be applied to the scenarios shown in the above figures, and are not limited thereto.

[0145] Referring to Figure 4, as an example, Figure 4 is a schematic diagram of a communication method 400 provided in an embodiment of this application. For ease of description, a terminal device and a network device are used as examples for illustrative purposes. The terminal device can be replaced by a terminal device or a component of a terminal device (e.g., a chip, chip system, circuit, or communication module), and the network device can be replaced by a component of a network device (e.g., a chip, chip system, circuit, or communication module). Furthermore, the steps described below as being performed by a single execution entity can also be divided into steps performed by multiple execution entities, which can be logically and / or physically separated. The method 400 shown in Figure 4 may include the following steps.

[0146] 410. The terminal device receives the configuration information. Accordingly, the network device sends the configuration information.

[0147] The configuration information indicates the first time unit among X first time units that can (or may) be used to transmit the wake-up signal. As an example, the configuration information indicates a first pattern, which specifies the first time unit among X first time units that can be used to transmit the wake-up signal. X is an integer greater than or equal to 1. For ease of description, the first pattern will be used as an example in the following illustration.

[0148] As an example, the first pattern indicates the first time unit among the X first time units that can be used to transmit the wake-up signal, which can also be replaced by: the first pattern indicating whether each of the X first time units can be used to transmit the wake-up signal.

[0149] For example, the first pattern directly indicates the first time unit among X first time units that can be used to transmit the wake-up signal.

[0150] For example, the first pattern directly indicates the first time unit among the X first time units that cannot be used to transmit the wake-up signal (such as denoted as X1 first time units, that is, X1 first time units are not used for the transmission of the wake-up signal). Thus, the first pattern can indirectly indicate the first time unit among the X first time units that can be used to transmit the wake-up signal. That is, the first time unit among the X first time units that can be used to transmit the wake-up signal is: the first time unit other than X1 first time units.

[0151] The first time unit, also known as the first time domain unit, represents the unit of time domain resources. In other words, the time domain resources of the wake-up signal may include one or more first time units. As an example, the unit of the first time unit can be any of the following: OOK symbol, OFDM symbol, slot, mini-slot, partial slot, subframe, radio frame, MO, etc.

[0152] The configuration information can also indicate the second time units among N second time units where the first pattern is applied. As an example, the configuration information indicates a second pattern that specifies the second time units among N second time units where the first pattern is applied. N is an integer greater than or equal to 1. For ease of description, the second pattern will be used as an example in the following illustrations.

[0153] As an example, the second pattern indicates the second time unit in which the first pattern is applied among N second time units, which can also be replaced by: the second pattern indicates whether the first pattern is applied to each of the N second time units.

[0154] For example, the second pattern directly indicates the second time unit in N second time units where the first pattern is applied.

[0155] For example, the second pattern directly indicates the second time unit among the N second time units that does not apply the first pattern (e.g., denoted as N1 second time units). Thus, the second pattern can indirectly indicate the second time unit among the N second time units that applies the first pattern. That is, the second time unit among the N second time units that applies the first pattern is: the second time unit other than the N1 second time units.

[0156] The second time unit, also known as the second time domain unit, represents the unit of time domain resources. In other words, the time domain resources of the wake-up signal may include one or more second time units. Each of the N second time units includes X first time units. For example, the N second time units include second time unit #1 and second time unit #2. Second time unit #1 includes X first time units, and second time unit #2 includes X first time units. In other words, the number of first time units contained in both second time unit #1 and second time unit #2 is X. As an example, the unit of the second time unit can be any of the following: OOK symbol, OFDM symbol, time slot, mini time slot, partial time slot, subframe, radio frame, MO, unit, etc. The units of the first time units and the units of the second time units may not be bound together. As mentioned above, a second time unit may include X first time units. For example, when the unit of the first time unit is an OFDM symbol, the unit of the second time unit can be an OFDM symbol, or it can be a time slot or a mini time slot, or it can be a unit.

[0157] It is understood that the wake-up signal transmitted in the time unit (such as the first time unit or the second time unit) mentioned in the embodiments of this application is not necessarily the wake-up signal of a specific terminal device, but rather a general wake-up signal. For example, suppose the network device sends a wake-up signal #1 in the first time unit #1. This wake-up signal #1 corresponds to waking up the first subgroup terminal device (or the first terminal device, or the first group of terminal devices) and is not used to wake up the second subgroup terminal device (or the second terminal device, or the second group of terminal devices). However, for the second subgroup terminal device, the resources occupied by the wake-up signal #1 are still "resources used for transmitting wake-up signals (i.e., the first time unit #1)".

[0158] It can also be understood that "time units (such as the first time unit, or the second time unit) are used to transmit wake-up signals" does not imply that a wake-up signal will necessarily be transmitted on that time unit. In other words, "time units are used to transmit wake-up signals" means that the time unit can or can be used to transmit wake-up signals. Whether or not a wake-up signal is transmitted may be related to other factors, such as whether there is a service requirement. For example, "the first time unit is used to transmit wake-up signals" means that the network device can send a wake-up signal on that first time unit. However, if there is no service requirement, the network device may not send a wake-up signal, meaning it will not send a wake-up signal on that first time unit.

[0159] 420. The terminal device monitors the wake-up signal based on the configuration information.

[0160] Specifically, the terminal device can determine the time-domain resource (i.e., the first time unit) of the wake-up signal corresponding to the terminal based on the first and second patterns, and then monitor the wake-up signal at that time-domain resource location. It can be understood that for a given terminal device, monitoring the wake-up signal is sufficient within the first time unit that can be used to transmit the wake-up signal; in other words, the terminal device does not need to monitor the wake-up signal in every first time unit that can be used to transmit the wake-up signal.

[0161] Optionally, the configuration information includes a first bitmap, which indicates the first time unit among X first time units used to transmit the wake-up signal.

[0162] For example, in the first bitmap, each bit corresponds to a first time unit. A bit with a first value indicates that the first time unit is used to transmit a wake-up signal, and a bit with a second value indicates that the first time unit is not used to transmit a wake-up signal. The first and second values ​​are different. For example, the first value is 0 and the second value is 1; or the first value is 1 and the second value is 0.

[0163] For example, X = 14, where X first time units constitute 14 symbols (i.e., X first time units form one time slot, which contains 14 symbols). Assuming the first value is 1 and the second value is 0, if the first bitmap is "00111111111111", it means that the first two first time units (i.e., the first two symbols in one time slot) are not used to transmit the wake-up signal, and the remaining first time units can be used to transmit the wake-up signal.

[0164] Optionally, the configuration information includes a second bitmap, which indicates the second time unit in N second time units where the first pattern is applied.

[0165] For example, in the second bitmap, each bit corresponds to a second time unit. A bit with a first value indicates that the first pattern is applied in the second time unit, and a bit with a second value indicates that the first pattern is not applied in the second time unit. The first and second values ​​are different. For example, the first value is 0 and the second value is 1; or the first value is 1 and the second value is 0.

[0166] For example, N=4, N second time units constitute 4 units, and each second time unit includes X first time units. Assuming the first value is 1 and the second value is 0, if the second bitmap is "1101", it means the first pattern is applied in the first, second, and fourth second time units, but not in the third second time unit. As an example, the third second time unit is not used to transmit a wake-up signal; that is, the X first time units in the third second time unit are not used to transmit a wake-up signal.

[0167] Optionally, the configuration information also indicates a first time period. In this case, in step 420, the terminal device monitors the wake-up signal based on the configuration information, including: the terminal device monitors the wake-up signal in a first time unit within the first time period that can be used to transmit the wake-up signal.

[0168] Here, the first time period represents the time-domain monitoring position of the wake-up signal. As an example, the first time period is LO. In this application, the first time period can be replaced with LO.

[0169] Optionally, the configuration information may also indicate at least one of the following: the length of the first time period, the offset of the first time period, the number of first time periods within a period, and the period of the first time period.

[0170] The length of the first time segment refers to the length of a single first time segment, such as the length of a single Loop (LO). For example, the unit for the length of the first time segment can be any of the following: OOK symbol, OFDM symbol, time slot, mini-time slot, partial time slot, subframe, radio frame unit, MO, etc.

[0171] The offset value of the first time period represents the offset of the first time period relative to a certain reference time (for distinction, this reference time is referred to as reference time #1). In one example, reference time #1 is the system time (such as the system frame number (SFN)). In another example, reference time #2 is the starting position of the paging frame (PF) or paging occasion (PO) associated with the first time period.

[0172] The period of the first time segment, also known as the period of the wake-up signal (periodicityOfLPWUS), represents the period during which the wake-up signal is monitored (or the monitoring period). In other words, it specifies how often a terminal device (or group of terminal devices) monitors the wake-up signal. For example, the period of the first time segment might be the period of idle discontinuous reception (iDRX). Alternatively, the period of the first time segment might be an integer multiple of the iDRX period. Or, the iDRX period might be an integer multiple of the period of the first time segment.

[0173] Optionally, the period of the first time segment is an integer multiple of N. For example, the starting positions of the N second time segments are associated with the starting position of the first time segment, thus ensuring that the period of the first time segment is an integer multiple of N. Here, "associated" means that the starting positions of the N second time segments are related to the starting position of the first time segment; in other words, the starting positions of the N second time segments can be determined based on the starting position of the first time segment, or vice versa. The relationship between the starting positions of the N second time segments and the starting position of the first time segment will be explained in detail later.

[0174] The number of first time periods within a cycle (or a monitoring cycle) indicates the number of first time periods within that cycle. For example, the number of first time periods within a cycle is related to the number of Product Objects (POs). For instance, the number of first time periods within a cycle is equal to the number of POs. Another example is that the number of first time periods within a cycle is an integer multiple of the number of POs. Yet another example is that the number of POs within a cycle is an integer multiple of the number of first time periods.

[0175] It is understandable that if at least one of the following is predefined or defaulted: the length of the first time period, the offset of the first time period, the number of first time periods within a period, and the period of the first time period, then the period of the first time period may not be included in the configuration information to save signaling overhead. For example, the period of the first time period can be predefined or defaulted to iDRX. As another example, the number of first time periods within a period can be predefined or defaulted to the number of POs.

[0176] As an example, the configuration information can be shown below. Parameters marked with square brackets indicate that they do not need to be explicitly configured separately, but rather their values ​​are determined in a predefined or default manner.

[0177] Based on this, it can be seen that the configuration information of the wake-up signal (such as the time-domain resources of the wake-up signal) is similar to the signaling structure of rateMatchPattern. Therefore, regardless of how the time-domain resources of the wake-up signal are configured, for other terminal devices (such as terminal devices receiving or transmitting NR signals), a single rateMatchPattern can be used to indicate the same set of resources for rate matching, meaning that there is no need to increase the number of rateMatchPattern sets. The meaning of the above parameters is explained below.

[0178] 1. “symbols” can represent the first pattern, that is, “symbols” can indicate the first time unit among X first time units used to transmit the wake-up signal.

[0179] As shown above, as an example, the X first time units can be one time slot or two time slots. One time slot includes 14 symbols, and two time slots include 28 symbols. For example, when the X first time units constitute one time slot, the first pattern can be a 14-bit bitstring. This 14-bit bitstring indicates which symbols in one time slot (i.e., among the 14 symbols) can be used to transmit the wake-up signal. In other words, the first pattern indicates whether each symbol in one time slot (i.e., among the 14 symbols) can be used to transmit the wake-up signal. As another example, when the X first time units constitute two time slots, the first pattern can be a 28-bit bitstring. This 28-bit bitstring indicates which symbols in two time slots (i.e., among the 28 symbols) can be used to transmit the wake-up signal. In other words, the first pattern indicates whether each symbol in two time slots (i.e., among the 28 symbols) can be used to transmit the wake-up signal.

[0180] 2. “periodicityAndPattern” can represent a second pattern, that is, “periodicityAndPattern” can indicate the second time unit in N second time units where the first pattern is applied.

[0181] As an example, `periodicityAndPattern` can indicate whether the first pattern is applied to each unit position within a period of length {1, 2, 4, 5, 8, 10, 20, or 40} units (i.e., 1 to 80 time slots). The above "n2" represents 2 units, where a unit may include 1 or 2 time slots. For example, if "symbols" indicates the symbols used to transmit the wake-up signal in 1 time slot (i.e., 14 symbols), then a unit includes 1 time slot, and correspondingly, n2 represents 2 time slots; if "symbols" indicates the symbols used to transmit the wake-up signal in 2 time slots (i.e., 28 symbols), then a unit includes 2 time slots, and correspondingly, n2 represents 4 time slots. n4, n5, n8, n10, n20, and n40 are similar and will not be elaborated upon here.

[0182] 3. "LengthOfOneLO" represents the length of a first time interval. "NumberOfLO" represents the number of first time intervals within a period. "PeriodicityOfLPWUS" represents the period of the first time interval. For details on these parameters, please refer to the previous explanations; they will not be repeated here.

[0183] To facilitate understanding, two diagrams are provided below for illustration.

[0184] Referring to Figure 5, as an example, Figure 5 is a schematic diagram of the time-domain resources of the wake-up signal according to an embodiment of this application. Assume that X first time units constitute one time slot, i.e., one second time unit includes one time slot; N=4, and four second time units comprise a total of four time slots. As shown in Figure 5, specifically, the first symbol (i.e., "symbols") = oneSlot(001111111111111), which indicates that in one time slot of 14 symbols, the first two symbols are not used to transmit the wake-up signal, and the latter 12 symbols can be used to transmit the wake-up signal. Furthermore, the second pattern (i.e., "periodicityAndPattern") = n4 (1101), which represents a period of 4 units (one unit includes one time slot, so 4 units include 4 time slots). In the 4 units, the time units that can be used to transmit wake-up signals are determined in the first, second, and fourth units according to the principle that "the first two symbols are not used to transmit wake-up signals, and the last 12 symbols can be used to transmit wake-up signals". As an example, in the third unit, all resources are not used to transmit wake-up signals. In addition, in the example shown in Figure 5, LengthOfOneLO is 4 time slots, and the period values ​​of LengthOfOneLO and periodicityAndPattern are the same, so a set of "periodic resources" appears in each LO (i.e., the first time period).

[0185] Referring to Figure 6, as an example, Figure 6 is another schematic diagram of the time-domain resources of the wake-up signal proposed according to an embodiment of this application. Assume that X first time units constitute one time slot, i.e., one second time unit includes one time slot; N = 2, and two second time units together include two time slots. As shown in Figure 6, specifically, “symbols” = oneSlot(001111111111111), which indicates that in one time slot of 14 symbols, the first two symbols are not used to transmit the wake-up signal, and the last 12 symbols can be used to transmit the wake-up signal. Further, periodicityAndPattern = n2(10), which indicates that the period is 2 units (one unit includes one time slot, therefore two units include two time slots). In the two units, in the first unit, the time units that can be used to transmit the wake-up signal are determined according to the method of “the first two symbols are not used to transmit the wake-up signal, and the last 12 symbols can be used to transmit the wake-up signal”. As an example, in the second unit, all resources are not used to transmit the wake-up signal. Furthermore, in the example shown in Figure 6, LengthOfOneLO is 4 time slots, and LengthOfOneLO is twice the period value of periodicityAndPattern. Therefore, in each LO (i.e. the first time period), there are 2 sets of "periodic resources", as shown in the first period and the second period in Figure 6.

[0186] Figures 5 and 6 above are merely specific examples, and the embodiments of this application are not limited thereto.

[0187] Optionally, the starting positions of the N second time units are associated with a reference time (referred to as reference time #2 for distinction). "Associated" means that the starting positions of the N second time units can be determined based on the reference time #2, such as the starting positions of the N second time units being the reference time #2, or the starting positions of the N second time units being the sum of the reference time #2 and an offset.

[0188] The first possible implementation is to use time #2 as the starting position of the first time period (e.g., LO).

[0189] Based on this method, the starting positions of the N second time units are associated with the starting position of the first time period. For example, the starting positions of the N second time units are the same as the starting position of the first time period. As shown in Figure 5, the starting positions of the N second time units (e.g., the starting position of periodicityAndPattern) are the same as the starting position of the first time period (e.g., the starting position of LO).

[0190] Specifically, taking the first time period as LO as an example, based on this implementation method, for a certain terminal device, when the terminal device determines the available time domain resources of the wake-up signal in its corresponding LO, it determines the starting position of its corresponding LO according to the configuration parameters of the LO; then, taking its corresponding LO starting position as a reference position, it determines the available time domain resources of the wake-up signal according to the first pattern and the second pattern, and then monitors the wake-up signal on the available time domain resources.

[0191] The second possible implementation uses the system time as the reference time #2. For example, the system time is SFN; specifically, SFN = 0 can be used as the reference time #2.

[0192] Referring to Figure 7, as an example, Figure 7 is another schematic diagram of the temporal resources of the wake-up signal according to an embodiment of this application. In Figure 7, each shaded square represents the location of a set of temporal resources indicated by the first pattern and the second pattern. The locations of the temporal resources used for the wake-up signal within each shaded square are the same, that is, each shaded square represents the location of a periodically occurring temporal resource indicated by the first pattern and the second pattern. Figure 7 is similar to Figure 5, except that in the example shown in Figure 7, the location of the first time period configured by the network device is shown as a dashed box. In this example, for a certain terminal device, the temporal resource location of the wake-up signal to be monitored by the terminal device can be the time unit that can be used to transmit the wake-up signal within the dashed box corresponding to the terminal device, that is, the time unit that can be used to transmit the wake-up signal within the dashed box corresponding to the terminal device, determined by the first pattern and the second pattern. In other words, the temporal resource location of the wake-up signal to be monitored by the terminal device is the intersection between the dashed box corresponding to the terminal device and the time unit that can be used to transmit the wake-up signal indicated by the first pattern and the second pattern.

[0193] Specifically, taking the first time period as LO as an example, based on this implementation method, for a certain terminal device, the system time (e.g., SFN=0) is used as a reference position, and the potential available time domain resources for the wake-up signal are determined according to the first pattern and the second pattern; then, the corresponding LO time window is determined according to the LO configuration parameters; the intersection of the two is the available time domain resources for the wake-up signal; then the terminal device monitors the wake-up signal on the available time domain resources.

[0194] The above example primarily illustrates the use of time-domain resources for the wake-up signal, but the embodiments of this application are not limited to this. For example, frequency-domain resources for the wake-up signal can also refer to the above method. For instance, a pattern (such as pattern #1) can indicate the first frequency-domain units among N first frequency-domain units that can (or may) be used to transmit the wake-up signal; another pattern (such as pattern #2) can indicate the second frequency-domain units among N second frequency-domain units that apply pattern #1. Each of the N second frequency-domain units includes X first frequency-domain units. Alternatively, another approach is that all frequency-domain resources corresponding to the wake-up signal may or may not be used for wake-up signal transmission. For example, within the time units indicated by the first and second patterns that can be used to transmit the wake-up signal, all frequency-domain resources can be used for wake-up signal transmission; within the time units indicated by the first and second patterns that are not used to transmit the wake-up signal, all frequency-domain resources are not used for wake-up signal transmission.

[0195] As mentioned earlier, a Loop (LO) includes T*K Mobile Origin (MO), where T represents the number of beams and K represents the number of MOs per beam. In the idle or inactive state, the number of beams is often represented by the number of synchronization signal blocks (SSBs). If an SSB burst set contains Z SSBs (also called candidate SSBs), then it can be considered that there are Z beam directions.

[0196] The number of SSBs in a set (i.e., the value of Z) can be predefined by the protocol. As an example, the number of SSBs in a set is related to the sub-carrier space (SCS) and / or the carrier frequency. In other words, the number of SSBs in a set may be different for different SCS and / or different carrier frequencies.

[0197] For example, for a half-frame containing an SSB, the index value of the first OFDM symbol of the candidate SSB is determined according to the SSB's SCS, with the following specific rules (where index value 0 corresponds to the first OFDM symbol of the first slot in the half-frame):

[0198] For Case A-SCS at 15kHz: the index value of the first OFDM symbol of each candidate SSB is {2,8}+14·n. Specifically, for channel access on unshared spectrum (i.e., licensed spectrum): when the carrier frequency is less than or equal to 3GHz, n = 0,1; when the carrier frequency is greater than 3GHz, n = 0,1,2,3. For channel access on shared spectrum (i.e., unlicensed spectrum), n = 0,1,2,3,4.

[0199] Case B-SCS is 30kHz: The index value of the first OFDM symbol of each candidate SSB is {4,8,16,20}+28·n. Where n=0 when the carrier frequency is less than or equal to 3GHz; and n=0 or 1 when the carrier frequency is greater than 3GHz.

[0200] Case C-SCS is 30kHz: The index value corresponding to the first OFDM symbol of each candidate SSB is {2,8}+14·n.

[0201] For channel access in the unshared spectrum (i.e., for licensed spectrum):

[0202] 1) For paired spectrum (i.e. FDD band), when the carrier frequency is less than or equal to 3GHz, n = 0, 1; when the carrier frequency is within FR1 and greater than 3GHz, n = 0, 1, 2, 3.

[0203] 2) For unpaired spectrum (i.e. TDD band), when the carrier frequency is less than or equal to 1.88 GHz, n = 0, 1; when the carrier frequency is within FR1 and greater than or equal to 1.88 GHz, n = 0, 1, 2, 3.

[0204] For channel access in shared spectrum (i.e., unlicensed spectrum), n = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

[0205] Case D-SCS is 120kHz: The index value of the first OFDM symbol of each candidate SSB is {4,8,16,20}+28·n. The carrier frequency is within FR2, n=0,1,2,3,5,6,7,8,10,11,12,13,15,16,17,18.

[0206] Case E-SCS is 240kHz: The index value of the first OFDM symbol of each candidate SSB is {8,12,16,20,32,36,40,44}+56·n. The carrier frequency is within FR2, n=0,1,2,3,5,6,7,8.

[0207] Case F-SCS is 480kHz: The index value corresponding to the first OFDM symbol of each candidate SSB is {2,9}+14·n. The carrier frequency is within FR2, n=0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31.

[0208] Case G-SCS is 960kHz: The index value corresponding to the first OFDM symbol of each candidate SSB is {2,9}+14·n. The carrier frequency is within FR2, n=0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31.

[0209] The above examples are for illustrative purposes only, and the embodiments of this application are not limited thereto.

[0210] In existing standards, a PO can contain Z MOs, and these Z MOs can have a one-to-one QCL relationship with Z SSBs. In other words, the signals on these Z MOs have a one-to-one QCL relationship with the Z SSBs. Here, the QCL relationship means that two signals have certain identical spatial parameters. In the embodiments of this application, it mainly means that the two signals have the same transmit beam (or transmit beam).

[0211] However, in the wake-up signal scenario, the number of beams associated with the wake-up signal may be different from the number of beams associated with the SSB, and the transmitted beam may be a horizontal beam or a vertical beam.

[0212] Referring to Figure 8, which is a schematic diagram of the beam as an example, when the beam (i.e., the transmit beam) of the network side is a horizontal beam, the beam is shown in Figure 8(a); when the beam (i.e., the transmit beam) of the network side is a vertical beam, the beam is shown in Figure 8(b) or Figure 8(c).

[0213] Wake-up signals typically use OOK modulation, which can result in poor coverage and weak anti-interference capabilities. Therefore, to reduce interference, when network devices use vertical beams to send wake-up signals, they may choose not to send the wake-up signal at the cell edge. As shown in Figure 8(c), at the cell edge, the network device does not send the wake-up signal. This results in a different number of beams associated with the wake-up signal compared to the number of beams associated with the SSB, with the wake-up signal associated with fewer beams than the SSB. Based on this, embodiments of this application also propose that the network device indicate the relevant information of the beams associated with the wake-up signal to the terminal device. The following detailed description is provided in conjunction with method 900. Method 900 and the preceding method 400 can be used individually or in combination, without limitation.

[0214] Referring to Figure 9, as an example, Figure 9 is a schematic diagram of a communication method 900 provided in an embodiment of this application. For ease of description, a terminal device and a network device are used as examples for illustrative purposes. The terminal device can be replaced by a terminal device or a component of a terminal device (e.g., a chip, chip system, circuit, or communication module), and the network device can be replaced by a component of a network device (e.g., a chip, chip system, circuit, or communication module). Furthermore, the steps described below as being performed by a single execution entity can also be divided into steps performed by multiple execution entities, which can be logically and / or physically separated. The method 900 shown in Figure 9 may include the following steps.

[0215] 910, the terminal device receives the indication information (for distinction, this indication information is referred to as indication information #1). Accordingly, the network device sends the indication information #1.

[0216] The indication information #1 indicates the SSB information associated with the wake-up signal. "Associated" can mean having a QCL relationship, that is, the SSB associated with the wake-up signal and the wake-up signal have a QCL relationship. Specifically, if the wake-up signal is associated with an SSB, then the wake-up signal and the SSB have a QCL relationship, meaning that the transmission beam of the wake-up signal and the transmission beam of the SSB are the same.

[0217] Optionally, the information of the SSB associated with the wake-up signal includes at least one of the following: the number of SSBs associated with the wake-up signal, the index of the SSBs associated with the wake-up signal, and the transmission beam of the SSBs associated with the wake-up signal.

[0218] The number of SSBs associated with the wake-up signal is less than or equal to the number of SSBs actually transmitted in an SSB set. As an example, the number of SSBs actually transmitted in an SSB set is determined based on at least one of the following: SCS, carrier frequency, and SSB positions in the set (ssb-PositionsInBurst). Specifically, network devices can configure ssb-PositionsInBurst to indicate which SSBs are actually transmitted among the candidate SSBs included in an SSB set. Therefore, for terminal devices, the number of SSBs included in an SSB set can be determined based on the SCS and / or carrier frequency, and optionally ssb-PositionsInBurst.

[0219] Optionally, indication information #1 may indicate an SSB in a set of SSBs that is associated with a wake-up signal.

[0220] One possible implementation is that the indication information #1 is implemented through a bitmap (referred to as the third bitmap for distinction). That is, the third bitmap indicates the SSB associated with the wake-up signal in a set of SSBs.

[0221] As an example, the number of bits in the third bitmap is either the maximum number of SSBs (or the number of candidate SSBs) in an SSB set or the number of SSBs actually transmitted in an SSB set. The number of bits in the third bitmap (i.e., the maximum number of SSBs in an SSB set) can be determined based on the SCS and / or carrier frequency, for example, referring to Cases A-G above. The number of SSBs actually transmitted in an SSB set can be determined based on the SCS and / or carrier frequency, or based on the SCS and / or carrier frequency, and further based on ssb-PositionsInBurst.

[0222] Two examples are given below.

[0223] Example 1: The number of bits in the third bitmap is the maximum number of SSBs in an SSB set.

[0224] In this example, each bit in the third bitmap corresponds to one SSB in a set of SSBs. The first value of the bit indicates that the SSB is associated with the wake-up signal, and the second value indicates that the SSB is not associated with the wake-up signal. The first and second values ​​are different. For example, the first value is 0 and the second value is 1; or the first value is 1 and the second value is 0.

[0225] For example, assuming the first value is 1 and the second value is 0, if the third bitmap is "0011", it means that the first two SSBs are not associated with the wake-up signal, and the last two SSBs are associated with the wake-up signal.

[0226] Example 2: The number of bits in the third bitmap is the number of SSBs actually transmitted in an SSB set.

[0227] This assumes that the actual number of SSBs transmitted in an SSB set is A, where A is an integer greater than or equal to 1, and A is less than or equal to the maximum number of SSBs in the SSB set. In this example, each bit in the third bitmap corresponds to one of the A SSBs. The first value of the bit indicates that the SSB is associated with the wake-up signal, and the second value indicates that the SSB is not associated with the wake-up signal. For a specific example, please refer to the description in Example 1.

[0228] Optionally, the terminal device receives indication information (referred to as indication information #2 for distinction). Accordingly, the network device sends indication information #2. Indication information #2 may indicate the information of the SSB actually transmitted in a set of SSBs. Indication information #2, for example, is ssb-PositionsInBurst as described above.

[0229] One possible implementation is that the indication information #2 is implemented using a bitmap (referred to as the fourth bitmap for distinction). That is, the fourth bitmap indicates the actual SSB transmitted within a set of SSBs.

[0230] The number of bits in the fourth bitmap can be the maximum number of SSBs (or the number of candidate SSBs) in an SSB set. The number of bits in the fourth bitmap (i.e., the maximum number of SSBs in an SSB set) can be determined based on the SCS and / or carrier frequency, for example, referring to Case A-Case G above.

[0231] For example, in the fourth bitmap, each bit corresponds to one SSB in a set of SSBs. The first value of a bit indicates that the SSB will be sent, and the second value indicates that the SSB will not be sent. The first and second values ​​are different. For example, the first value can be 0 and the second value can be 1; or the first value can be 1 and the second value can be 0.

[0232] 920, based on indication information #1, the terminal device monitors the wake-up signal.

[0233] Specifically, the terminal device can monitor the wake-up signal of the terminal device based on the indication information #1.

[0234] Optionally, the first time period includes K groups of MOs, each group of MOs includes T MOs, where T represents the number of bits in the third bitmap that take the first value, and K is an integer greater than or equal to 1. Based on this, the first time period includes K*T MOs. Further optionally, the wake-up signals transmitted on the T MOs in each group of MOs carry the same information.

[0235] Optionally, there is a one-to-one correspondence between T MOs and T SSBs, and the wake-up signals transmitted on the T MOs have a QCL relationship with the T SSBs. Taking a certain MO (e.g., denoted as MO#1) as an example, MO#1 corresponds to SSB#1, and the wake-up signal transmitted on MO#1 has a QCL relationship with SSB#1. That is, the transmission beam of the wake-up signal sent by the network device on MO#1 is the same as the transmission beam of the network device sending SSB#1.

[0236] It is understood that in various embodiments of this application, "monitoring" can also be replaced with "detecting" or "reading". For example, "monitoring wake-up signal" can also be replaced with "detecting wake-up signal" or "reading wake-up signal".

[0237] It is also understood that in the above embodiments, the repeated mention of "time unit for transmitting wake-up signal" or "time unit for transmitting wake-up signal" indicates that the time unit can or can be used to transmit wake-up signal, but does not limit the transmission of wake-up signal to that specific time unit. In other words, if the network device needs to send a wake-up signal, the network device can send the wake-up signal in the time unit that can be used to transmit the wake-up signal; if the network device does not send a wake-up signal (e.g., there is no service requirement, or it is not necessary to wake up the terminal device), then the wake-up signal will not be sent in the time unit that can be used to transmit the wake-up signal.

[0238] It is also understood that in some of the above embodiments, the term "transmission" is used, and unless otherwise specified, transmission includes receiving and / or sending. For example, transmitting a signal may include receiving a signal and / or sending a signal.

[0239] It is also understood that in the various embodiments of this application, if the terminal device learns that it has been woken up, such as by learning that it has been woken up based on a wake-up signal, the terminal device can immediately access the network device, or the terminal device can access the network device at intervals, without restriction.

[0240] It is also understood that in some of the above embodiments, the main circuit and wake-up circuit are mainly used as examples for illustrative purposes, and this application is not limited thereto. For example, "wake-up circuit" can also be replaced with "first module", or "wake-up link", or "in a first state", or "in a first mode". For example, "the terminal device receives a signal using 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". "Main circuit" can also be replaced with "second module", or "main link", or "in a second state", or "in a second mode". For example, "the terminal device receives a signal using 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".

[0241] It is also understood that, in the various embodiments of this application, the interaction between a terminal device and a network device is mainly used as an example for illustrative purposes. This application is not limited thereto. The terminal device can be replaced by a receiving device, which can be either a terminal device or a network device; the network device can be replaced by a sending device, which can be either a terminal device or a network device. For example, "terminal device" can be replaced by "first terminal device," and "network device" can be replaced by "second terminal device."
