Wearable devices may also be called wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0049] FIG1 exemplarily illustrates a communication system 100. The communication system includes a network device 110 and two terminal devices 120. In one embodiment, the communication system 100 may include multiple network devices 110, and each network device 110 may include a different number of terminal devices 120 within its coverage area, which is not limited in this embodiment of the present application.

[0050] It should be understood that in the embodiments of the present application, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system shown in Figure 1 as an example, the communication device may include a network device and a terminal device having a communication function. The network device and the terminal device may be specific devices in the embodiments of the present application and will not be described in detail here. The communication device may also include other devices in the communication system, such as a network controller, a mobility management entity, and other network entities, which are not limited in the embodiments of the present application.

[0051] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0052] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.

[0053] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0054] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0055] To conserve power in terminals, existing communication systems support the DRX (Discontinuous Reception) transmission mechanism. This mechanism uses a semi-static configuration to achieve discontinuous reception of signals in the time domain. When there is no data transmission, power consumption can be reduced by stopping PDCCH (Physical Downlink Control Channel) reception and PDCCH blind detection.

[0056] Configuring DRX involves configuring a DRX cycle for a UE in the RRC_CONNECTED state. As shown in Figure 2, the DRX cycle consists of an active time and an inactive time. During the active time, the UE monitors and receives the PDCCH; during the inactive time (sleep period), the UE does not receive the PDCCH to reduce power consumption.

[0057] In the energy-saving enhancement of NR, the DRX mechanism can also be used in conjunction with the wake-up signal mechanism. Specifically, the terminal receives an indication of an energy-saving wake-up signal before the DRX ON duration. As shown in Figure 2, when the terminal has data transmission in a DRX cycle, the energy-saving wake-up signal "wakes up" the terminal to detect the PDCCH during the DRX ON duration; otherwise, when the terminal has no data transmission in a DRX cycle, the energy-saving wake-up signal does not "wake up" the terminal, and the terminal does not need to detect the PDCCH during the DRX ON duration. Therefore, when the terminal has no data transmission, the terminal can omit the PDCCH detection during the DRX ON duration, thereby achieving energy saving. The time of the terminal before the DRX ON duration is called the inactive time. The time of the terminal during the DRX ON duration is called the active time.

[0058] In the above energy-saving enhancement technology, the energy-saving wake-up signal itself also adopts a waveform and structure similar to that of the PDCCH.

[0059] FIG3 is a schematic flow chart of a transmission method according to an embodiment of the present application. The method can optionally be applied to the system shown in FIG1 , but is not limited thereto. The method includes:

[0060] S310. The terminal device receives first indication information from the network device; wherein the first indication information is used to indicate transmission of a first channel, and the first indication information is carried by a first signal based on sequence modulation.

[0061] Optionally, the first indication information can be used to activate the terminal device to transmit and receive the first channel. Accordingly, upon receiving the first indication information, the terminal device performs transmission and reception on the first channel; upon not receiving the first indication information, the terminal device does not need to perform transmission and reception on the first channel. Transmission and reception of the first channel herein may refer to receiving and / or transmitting the first channel.

[0062] Optionally, the terminal device may transmit and receive the first channel at a predetermined time domain position, or transmit and receive the first channel at a time domain position associated with the first indication information, wherein the first channel may be a control and / or data channel.

[0063] Optionally, the first indication information may include a wake-up indication and a detection indication for the first channel. The first indication information may also include one or more information such as the type, number, resource configuration, and terminal device-related ID (Identifier) ​​of the first channel. In some descriptions, the first indication information may also be referred to as a detection indication channel.

[0064] Illustratively, the first indication information includes at least one of the following: a terminal ID of the terminal device; a group ID associated with the terminal device (e.g., the group ID of the group to which the terminal device belongs); or a cell ID associated with the terminal device (e.g., the ID of the cell to which the terminal device belongs). The inclusion of the terminal device-related ID in the first indication information enables the terminal device to determine that the first indication information is used to schedule the terminal device to transmit and receive on the first channel.

[0065] Corresponding to the above method, FIG4 is a schematic flow chart of a transmission method according to another embodiment of the present application. The method can optionally be applied to the system shown in FIG1 , but is not limited thereto. The method includes:

[0066] S410. The network device sends first indication information to the terminal device; wherein the first indication information is used to indicate transmission of a first channel, and the first indication information is carried by a first signal based on sequence modulation.

[0067] In an embodiment of the present application, the network device sends the first indication information based on sequence modulation, so that the first indication information can be correctly received through simple receiver processing. Therefore, the terminal device can use a terminal receiver with lower power consumption and lower complexity for reception, thereby reducing terminal power consumption and optimizing terminal energy-saving technology.

[0068] Optionally, the sequence in the embodiment of the present application may include a complex (vector) sequence such as a CAZAC sequence (Constant Amplitude Zero Auto Correlation) sequence, a ZC (Zaddoff Chu) sequence, or may include a PN (Pseudo-Noise) sequence, a Gold sequence, an M sequence, a Hadamard sequence, or other real sequences.

[0069] In some embodiments, the first signal includes one or more OFDM (Orthogonal Frequency Division Multiplexing) symbols obtained based on sequence modulation. That is, the modulation method of the first indication information is to modulate the sequence carrying the first indication information onto one or more OFDM symbols. Accordingly, the terminal device can determine the sequence used to carry the first indication information through the one or more OFDM symbols, and then determine the first indication information based on the sequence.

[0070] In some embodiments, the first signal is modulated based on at least one sequence; the at least one sequence includes a first sequence related to the first indication information determined based on a sequence selection method. Accordingly, the terminal device may demodulate the received first signal to obtain at least one sequence, including the first sequence related to the first indication information.

[0071] The sequence selection method refers to selecting a sequence corresponding to a specific bit of information from a sequence set, and using the sequence to carry the specific bit of information. For example, the first indication information includes at least n bits of information, and the first sequence is the first sequence selected from the sequence set corresponding to the n bits of information. Optionally, the sequence set includes 2 n 2 values ​​corresponding to each other n sequences, so that n bits of information can be represented by sequence selection.

[0072] In some embodiments, the first signal includes a first OFDM symbol, and a plurality of subcarriers in the first OFDM symbol are mapped based on a first sequence.

[0073] Exemplarily, if the length of the first sequence is m, the first sequence can be represented as y(1) to y(m), and y(1) to y(m) are directly mapped to a group of continuous subcarriers (m subcarriers) without any pre-transformation. Based on the m subcarriers, a first OFDM symbol can be obtained, that is, a waveform output in the time domain is generated by the modulation method of the OFDM symbol. Optionally, the value of m is one of {2, 4, 6, 8, 12, 16, 24, 36, 48, 60, 72} or other positive integers.

[0074] Figure 5 shows a schematic diagram of sequence modulation in an embodiment of the present application. As shown in Figure 5, the first indication information may include 4 bits of information "1010". The network device obtains the first sequence through sequence selection and directly maps the first sequence to m subcarriers to obtain an OFDM symbol. The network device transmits the first indication information by transmitting the OFDM symbol.

[0075] In some embodiments, the first sequence is a sequence corresponding to the first part of the information in the first indication information; the at least one sequence used to modulate to obtain the first signal also includes a second sequence, and the second sequence corresponds to the second part of the information in the first indication information.

[0076] Exemplarily, the first indication information includes at least two parts of information, wherein the first part of information is n-bit information, and the second part of information is k-bit information (k and n may be equal or different, and both k and n are positive integers). The first sequence is a sequence corresponding to the above n-bit information, used to represent (or carry) the above n-bit information; the second sequence is a sequence corresponding to the above k-bit information, used to represent (or carry) the above k-bit information. The first sequence is mapped to multiple subcarriers to be sent via OFDM symbols; the second sequence may be sent in the same manner or a different manner.

[0077] In some embodiments, the first signal further includes a second OFDM symbol, and the second OFDM symbol is obtained by performing time domain spreading based on the second sequence.

[0078] Optionally, the first signal may include one or more second OFDM symbols, and the network device may perform time-domain spreading on the first OFDM symbol based on the second sequence to obtain one or more second OFDM symbols.

[0079] The above embodiment carries the first indication information containing more bit information by means of time domain spread spectrum, and the correlation between OFMD symbols is strong, which is conducive to the terminal device to correctly demodulate and obtain the first indication information.

[0080] In some embodiments, the first signal further includes a third OFDM symbol concatenated with the first OFDM symbol, and a plurality of subcarriers in the third OFDM symbol are obtained based on the second sequence mapping.

[0081] Exemplarily, the second sequence may be a sequence corresponding to the second portion of information in the first indication information, determined by sequence selection. Similarly, a second sequence of length z (z is a positive integer) may be directly mapped to z subcarriers without pre-transformation to obtain a second OFDM symbol, so as to carry the second sequence, i.e., the second portion of information in the first indication information, through the second OFDM symbol. The first OFDM symbol and the second OFDM symbol are concatenated in the time domain.

[0082] According to the above embodiment, more information bits can be carried based on the sequence modulation method, which is conducive to achieving correct transmission of the first indication information through simple receiver processing.

[0083] In some embodiments, the first channel is transmitted based on coded modulation.

[0084] Optionally, the network device may perform channel coding on the original information of the first channel to form a coded bit sequence, then modulate the bit sequence onto multiple modulation symbols, map the multiple modulation symbols onto subcarriers of an OFDM symbol, and send them through the OFDM symbol.

[0085] In some embodiments, the first channel may be used to carry control information and / or data information. For example, the first channel may include a control channel for carrying control information and / or a data channel for carrying data information, or the first channel may include a joint channel for carrying both control information and data information. The control channel is, for example, a PDCCH or a PUCCH (Physical Uplink Control Channel). The data channel is, for example, a PDSCH (Physical Downlink Shared CHannel) or a PDCCH.

[0086] Figure 6 is a schematic diagram of an application example of the transmission method in an embodiment of the present application. In Figure 6, the first channel includes a control channel as an example for illustration, and the first indication information is used to indicate that there is a transmission of the control channel. The first indication information is sent according to the control indication period. In each period, if the first indication information is received, the terminal device detects the control channel in one or more time slots associated with the period (two time slots are used as an example for illustration in Figure 6), and transmits the data channel according to the control channel; if the first indication information is not received, the terminal device does not detect the control channel in one or more time slots associated with the period, and thus there is no data channel transmission. As shown in Figure 6, the terminal device receives the first indication information within the control indication period, and therefore detects the control channel PDCCH on the nth time slot (slot n) and the n+1th time slot (slot n+1) associated with the control indication period, and transmits the data channel according to the PDCCH.

[0087] Figure 7 is a schematic diagram of another application example of the transmission method in an embodiment of the present application. In Figure 7, the first channel includes a control and data joint channel (i.e., a channel containing control information and data information) as an example for illustration, and the first indication information is used to indicate the transmission of the control and data joint channel. The first indication information is sent according to the control indication period. In each period, if the first indication information is received, the terminal device detects the control and data joint channel in one or more time slots associated with the period (two time slots are used as an example for illustration in Figure 7) to receive control information and data information; if the first indication information is not received, the terminal device does not detect the control and data joint channel in one or more time slots associated with the period. As shown in Figure 7, the terminal device receives the first indication information in the control indication period, and therefore detects the control and data joint channel on the nth time slot (slot n) and the n+1th time slot (slot n+1) associated with the control indication period to obtain control information and data information.

[0088] In some embodiments, the first channel is associated with first resource information. Here, the first resource information is a resource associated with the first channel, and the terminal device can use a configuration corresponding to the first resource information to perform transmission and reception of the first channel.

[0089] Optionally, the first indication information may indicate first resource information associated with the first channel, so that the terminal device can determine the first resource information. Alternatively, the association between the first channel and the first resource information is preconfigured, and the terminal device can determine the first resource information when determining to transmit or receive the first channel based on the first indication information.

[0090] In some embodiments, the first resource information includes at least one of the following information A to G, or in other words, the first resource information includes information of at least one dimension of the following information A to G:

[0091] A. Time information;

[0092] The time information may include the time domain position of the transceiver channel, or the time interval of the transceiver channel. For example, the time interval for transmitting and receiving the PDCCH or PDSCH in units of slots may be once per slot, once every two slots, once every four slots, or once every eight slots.

[0093] B. frequency domain information of the first channel;

[0094] The frequency domain information may include bandwidth. Taking RB (Resource Block) units as an example, the bandwidth of the first channel is x RBs, where the number x of RBs may be one of {12, 25, 50, 100}.

[0095] C. Airspace information;

[0096] The information is, for example, the number of antennas for transmitting and receiving channels or the number of channel layers.

[0097] D. Control the amount of information;

[0098] The amount of control information may be the amount of control information in a control channel, or the amount of control information in a joint control and data channel.

[0099] E. Data throughput;

[0100] The data throughput may be the amount of control information in a control channel, or the amount of control information in a joint control and data channel.

[0101] F. Measure throughput;

[0102] The measured throughput may include the amount of measurement that the terminal device needs to perform and / or report measurement.

[0103] G. Computational throughput of terminal devices.

[0104] The computing throughput of the terminal device may include the number of floating-point operations (FLOPs) per unit time of the terminal device, etc.

[0105] It should be noted that the first resource information includes at least one of information A to G, indicating that the first channel can be associated with only one of specific time information, frequency domain information, spatial domain information, control information volume, data throughput, measurement throughput, and computation throughput, or can be associated with a combination of multiple information from information A to G. For example, the first channel can be associated with specific time information, frequency domain information, and spatial domain information. For another example, the first channel can be associated with a certain amount of control information, data throughput, and measurement throughput. In actual applications, the first resource information associated with the first channel information can be set based on scenario requirements or system agreements.

[0106] It can be understood that the above information is related to the processing capability of the terminal device. For example, the processing capability of the terminal device may include the time interval at which the terminal device can receive and send the first channel, the bandwidth of the first channel that the terminal device can receive and send, the number of antennas of the terminal device or the number of channel layers, the amount of control information or data throughput of the first channel that the terminal device can receive and send uplink or downlink, the amount of measurement and reported measurement that the terminal device can perform, and the computing throughput of the terminal device. In this way, when the first channel is associated with the first resource information, the first channel is also associated with the terminal processing capability corresponding to the first resource information. In some embodiments, the first indication information is also used to instruct the terminal device to switch to use the processing capability corresponding to the first resource information.

[0107] Optionally, the terminal device may support multiple processing capabilities (or processing cores). Among them, a small processing capability corresponds to a lower capability item in at least one dimension, for example, the time interval at which the terminal device can send and receive the first channel is longer or the bandwidth of the first channel that the terminal device can send and receive is smaller; a large processing capability corresponds to a higher capability item in at least one dimension, for example, the amount of control information of the first channel that the terminal device can send and receive is larger or the measurement throughput related to the first channel that the terminal device can perform is larger. When the first channel is associated with the first resource information, the terminal device switches to use the processing capability corresponding to the first resource information among the multiple processing capabilities it supports.

[0108] In some embodiments, the terminal device supports a first processing capability and a second processing capability, and the first processing capability includes the second processing capability. In other words, the plurality of processing capabilities supported by the terminal device include the first processing capability and the second processing capability. The first processing capability and the second processing capability may overlap.

[0109] Figure 8 is a schematic diagram of the processing capabilities of a terminal device in an embodiment of the present application. As shown in Figure 8, the terminal device supports at least one large processing core and one small processing core, wherein the capabilities of the small processing core are included in the large processing core. The first indication information can be used to instruct the terminal device to switch to using one of the processing cores, or to activate one of the processing cores. Optionally, the first indication information may include an indication of the first channel, and an indication of the first resource information associated with the processing core or the processing core. Alternatively, the first indication information may include an indication of the first channel, wherein the first channel has been associated with the first resource information, and the terminal device can determine the processing core that needs to be switched based on the first indication information.

[0110] In related technologies, terminals are designed to support extremely high peak rates. Therefore, they require high-performance capabilities. The LTE standard defines a maximum single-carrier bandwidth of 20 MHz (megahertz), with larger bandwidths achieved through multi-carrier aggregation. 5G NR ultimately defines a maximum carrier bandwidth of 100 MHz for frequency bands below 6 GHz (gigahertz), which is already five times that of LTE. The maximum carrier bandwidth for millimeter-wave frequency bands is 400 MHz. The MIMO (Multiple Input Multiple Output) antenna size required for NR has also been further increased. The reference antenna configuration for LTE terminals is one transmit and two receive antennas, while NR Release 15 requires two transmit and four receive antennas for frequencies above 2500 MHz. NR Releases 15 and 16 also lack support for half-duplex, requiring data processing in all uplink and downlink slots. However, in terms of processing capacity and speed, some NR application scenarios, such as the Internet of Things, industrial automation, and wearable devices, do not require such high processing capabilities. These scenarios require communication hardware with a small size and low power consumption. Lightweight capabilities are a hallmark of these terminals. Based on such considerations, NR R17 introduced a compact terminal standard with reduced capabilities. The compact terminal standard reduces some of the mandatory capabilities of NR R15 / 16. Corresponding terminal function groups are defined for such capabilities. The compact terminal standard also further optimizes terminal identification, access processes, and power consumption in measurements to adapt to relevant application scenarios. The design of such a compact terminal can significantly reduce the complexity of terminal hardware. At the same time, it can also reduce the energy consumption of the terminal accordingly, thereby achieving energy saving. However, the introduction of compact terminals often customizes the terminal transceiver according to fixed capability specifications, and the transceiver cannot be designed in a modular manner, nor can some transceivers be switched on and off modularly according to data capacity. By adopting the above embodiment, the terminal device can adaptively turn on and off the transceiver partially according to performance requirements such as data throughput, and by defining the minimum processing core that is generally supported, it is ensured that terminals of different capability types can universally access the network. When the terminal requires a larger data throughput, it switches to a larger processing core. This allows the terminal's transceiver to be customized without fixed capacity specifications. The terminal's transceiver can be designed in a modular manner. Ultimately, the terminal can also modularly switch some transceivers based on data capacity, achieving dynamic energy saving.

[0111] In some embodiments, the first indication information is further used to instruct the terminal device to adjust configuration parameters of the first channel and / or measurement parameters related to the first channel.

[0112] Accordingly, in some embodiments, the transmission method further includes:

[0113] The terminal device adjusts the configuration parameters of the channel transmission within the first time window based on the processing capability corresponding to the first resource information; wherein the length of the first time window is related to the configuration parameters before adjustment.

[0114] Exemplarily, the configuration parameters may include parameters of the receiving or transmitting channel, such as a time interval, bandwidth (e.g., number of RBs), etc. Based on the processing capability corresponding to the first resource information, the terminal device adjusts the time interval and bandwidth for transmitting and receiving the first channel to match the processing capability in a first time window after receiving the first indication information. The first time window is, for example, k time slots, where the value of k is determined based on the bandwidth and time interval of the transmitting and receiving channel before the conversion.

[0115] In some embodiments, the transmission method further comprises:

[0116] The terminal device adjusts the measurement parameters related to the first channel based on the processing capability corresponding to the first resource information.

[0117] Exemplarily, the measurement parameter may include measurement parameters when the terminal device performs measurement related to the first channel, such as measurement bandwidth (such as the number of RBs), time interval, etc. The first indication information triggers corresponding measurement adaptive adjustment while indicating the switching of processing capability.

[0118] In some embodiments, the transmission method further comprises:

[0119] The terminal device transmits and receives the first channel at one or more time-frequency positions associated with the time-frequency position of the first indication information.

[0120] Optionally, the time-frequency position of the first indication information may be understood as the time-frequency position at which the first indication information is sent or received.

[0121] According to the above embodiment, the time-frequency position of transmitting and receiving the first channel is associated with the time-frequency position of the first indication information. Optionally, the frequency of transmitting and receiving the first channel can be associated with the frequency of the first indication information, for example, the frequency is the same or similar; and / or the time or time domain position of transmitting and receiving the first channel can be associated with the first indication information, for example, the time of transmitting and receiving the first channel is determined based on the time domain position of the first indication information and a first time interval, where the first time interval can be pre-configured, for example, a network configuration or a default configuration.

[0122] In some embodiments, the control information and data information in the first channel are mapped onto a group of related OFDM symbols when transmitted.

[0123] For example, when the first channel includes control information and data information, that is, when the first channel is a joint control and data channel, the control information and the data information can be carried by associated OFDM symbols. Optionally, the network device can perform channel coding on the control information and the data information and map them to a group of related OFDM symbols, so that the terminal device can accurately obtain the control information and the data information based on the correlation of the OFDM symbols.

[0124] In some embodiments, the relevant OFDM symbols include consecutive OFDM symbols in the time domain. Optionally, control information is mapped to the preceding OFDM symbol in the time domain, and data information is mapped to the following OFDM symbol in the time domain. The control information can provide scheduling information such as the time-frequency domain resources, modulation method, and number of layers occupied by the data information, thereby enabling the terminal device to accurately receive the data information.

[0125] In some embodiments, the control information and data information in the first channel are mapped to frequency-domain adjacent subcarriers on a group of related OFDM symbols when being transmitted.

[0126] According to this embodiment, the control information and data information in the first channel are correlated in the time domain and adjacent in the frequency domain. Therefore, the channel responses of the control information and the data information can be consistent or close. This characteristic can be used for channel estimation, which is beneficial to saving resource overhead.

[0127] As can be seen, the wake-up signal received by terminal devices in the related art uses a PDCCH structure, which is still relatively energy-consuming. Furthermore, without multi-level processing capabilities, the terminal can only report a fixed processing capability, and the terminal's processing capability remains unchanged after accessing the network. However, according to embodiments of the present application, the introduction of sequence-modulated first indication information allows reception using a terminal receiver with lower power consumption and complexity, thereby determining whether it is necessary to activate a more power-consuming control / data receiver. This operation can effectively optimize terminal power consumption. In some embodiments, the sequence-modulated first indication information can also be used to allow the terminal to adaptively turn on and off parts of the transceiver based on performance requirements such as data throughput. By defining a universally supported minimum processing core, terminals of different capability types can universally access the network. When a terminal requires higher data throughput, it switches to a larger processing core. Such terminals no longer need to customize their transceivers according to fixed capability specifications. Terminal transceivers can be designed in a modular manner. Ultimately, the terminal can also modularly turn on and off parts of the transceiver based on data capacity, achieving dynamic energy conservation.
