Description

A method for sending information CROSS-REFERENCE TO RELATED APPLICATIONS This disclosure is based on Chinese patent application CN202410175173.0 filed on February 7, 2024, entitled “A Method for Sending Information”, and claims the priority of the patent application, and all the contents disclosed therein are incorporated into this disclosure by reference. Technical Field The present disclosure relates to the field of communications, and in particular, to a method for sending information. Background Art For 5G systems, in addition to latency, reliability, and availability, energy efficiency of user equipment (UE) is also crucial. Currently, UEs may need to be charged weekly or daily, depending on individual usage. Typically, UEs consume tens of milliwatts of power in the Radio Resource Control (RRC) idle / inactive state and hundreds of milliwatts in the RRC connected state. Designing for extended battery life is essential for improving energy efficiency and user experience. Power consumption depends on the length of the configured wake-up cycle, such as the paging cycle. In order to meet the battery life requirements, it is expected that the higher-value Extended Discontinuous Reception (eDRX) cycle will be used, resulting in high latency, which is not suitable for service types that require both battery life and low latency. Therefore, the relevant technology considers introducing a low-power wake-up signal (LP-WUS) mechanism, that is, the UE uses a separate receiver to receive a low-power wake-up signal, and uses the low-power wake-up signal to wake up the main wireless device (Main Radio) for data transmission and data reception. When the UE does not detect the low-power wake-up signal, the main receiver is in a deep sleep state, which further reduces the power consumption of the UE. However, there is no definite solution on how to carry information in the low-power wake-up signal. In summary, how to carry information in a low-power wake-up signal has become a technical problem that needs to be solved urgently. Summary of the Invention The embodiments of the present disclosure provide a method for sending information to at least solve the problem of low-power wake-up signals carrying information in related technologies. According to an embodiment of the present disclosure, a method for sending information is provided, the method comprising: sending a target signal carrying target information, wherein the target signal occupies multiple target symbols in the time domain. According to another embodiment of the present disclosure, a computer-readable storage medium is provided, in which a computer program is stored. When the computer program is executed by a processor, the steps of any of the above method embodiments are executed. According to another embodiment of the present disclosure, an electronic device is provided, including a memory and a processor, wherein the memory stores a computer program, and the processor is configured to run the computer program to perform the steps in any one of the above method embodiments.

DETAILED DESCRIPTION Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. The method embodiment provided in the embodiment of the present disclosure can be implemented based on the LP-WUS mechanism in the 5G system. The wake-up signal is an important energy-saving mechanism. By sending a wake-up signal (WUS for short), the UE can detect the WUS signal before the UE paging message arrives when entering any mode of the idle (RRC_IDLE) mode, the inactive (RRC_INACTIVE) mode, and the connected (RRC_CONNECTED) mode, so that the UE turns on the receiver to receive the paging message, thereby avoiding the UE detecting the paging message when there is no UE paging message and consuming a lot of power. At the same time, in the connected (RRC_CONNECTED) mode, the UE can also determine whether there is a scheduling arrival by detecting the WUS signal. When the UE detects the WUS signal, the UE turns on the receiver to receive the physical downlink control channel (PDCCH for short) information, thereby avoiding the UE detecting the PDCCH when there is no UE scheduling information and consuming a lot of power. The method embodiments provided in the embodiments of the present disclosure may be executed in a mobile terminal, a computer terminal, or a similar computing device, and may also be applied to a communication node such as a base station. In one embodiment of the present disclosure, a method for sending information is provided.

As shown in FIG1 , the flow chart includes the following steps: Step S102: Send a target signal carrying target information, wherein the target signal occupies at least one target symbol in the time domain. In this embodiment, the target signal can be generated based on modulation methods such as On-Off Keying (OOK) modulation and Multi-Carrier On-Off Keying (MC-OOK) modulation, and the present disclosure does not impose any restrictions on this.

In an exemplary embodiment, the target information may be carried by OOK symbols or MC-OOK symbols, or may be carried by OFDM symbols, wherein each OFDM symbol may be divided into one or more OOK symbols or MC-OOK symbols. In some embodiments, the target information includes at least one of the following: first category information; second category information, wherein the second category information is part of the first category information; third category information, wherein the third category information is part of the first category information that is different from the second category information; fourth category information, wherein the fourth category information is information different from the first category information; first indication information.

Among them, CRC is an algorithm used to detect or verify whether there is an error in data or information transmission. The main function of the padding information is to ensure that the length of the data packet meets specific requirements. In wireless communication protocols, the size and format of the data packet must meet specific standards to ensure that the data can be transmitted and parsed correctly. When the size of a data packet does not meet the standard, padding information is required to increase the length of the data packet to the required length. The padding information can be specific characters or binary data used to occupy excess space in the data packet. The present disclosure does not limit the specific content of this padding information. In this embodiment, the first indication information is used to indicate at least one of the following: Position information of the second number of target symbols within the first number of target symbols; the size of the payload of the first type of information; the size of the payload of the second type of information; value information of the second quantity; The number of bits or elements contained in a set of information; The number of states corresponding to the bits or elements contained in one of the information sets; the number of third sequences required for the states corresponding to the bits or elements contained in one of the information sets; Whether the second type of information or the sixth type of information contains cyclic redundancy check (CRC) information and / or padding information; whether the second type of information or the sixth type of information is sent repeatedly; the number of times the second type of information or the sixth type of information is repeatedly sent; whether the second type of information or the sixth type of information is sent by frequency hopping; a frequency hopping transmission pattern of the second type of information or the sixth type of information.

In this embodiment, the size of the payload of the wake-up signal information is the number of bits that carry the wake-up signal information. Exemplarily, the size may be 8 bits, 16 bits, 24 bits, or a larger payload. Furthermore, the size of the payload can be determined by the length of the Low Power Synchronization Signal (LP-SS) or the Low Power Preamble (LP-Preamble). For example, when the LP-SS or LP-Preamble length is 16 OOK symbols, the corresponding wake-up information payload is 8 bits; when the LP-SS or LP-Preamble length is 32 OOK symbols, the corresponding wake-up information payload is 24 bits.

Furthermore, an OFDM symbol may include multiple OOK symbols or MC-OOK symbols. Exemplarily, if the target symbol is an OOK symbol or a MC-OOK symbol, the second type of signal occupies a second number of OOK symbols or MC-OOK symbols in the time domain. If the target symbol is an OFDM symbol, the second type of signal occupies a second number of OFDM symbols in the time domain. In some embodiments, the first type of signal includes at least one of the following: a first signal, a second signal, and a third signal.

For a vector X, FFTSHIFT(X) swaps the left and right halves of X or the top and bottom halves of X. For a matrix X, FFTSHIFT(X) swaps the first and third quadrants, or the second and fourth quadrants. Step S204: Data information DK Fill the K subcarriers in the frequency domain; when the overall frequency domain bandwidth of the system includes N subcarriers, an N-point Inverse Discrete Fourier Transform (IDFT) or N-point Inverse Fast Fourier Transform (IFFT) operation is performed on the filling data on the N subcarriers to obtain the time domain data T of N sampling points.

Example 1 Taking the LP-WUS signal as an example, the transmission of LP-WUS will occupy at least one OFDM symbol, and the data information carried during transmission Length L B It is 16 bits and can be expressed as: Among them, b0, b1, b2, b3, b4, b5, b6, b7 are the source information bits, and b8, b9, b 10 ,b 11 ,b 12 ,b 13 ,b 14 ,b 15 is the CRC bit. In this embodiment, the data information can be The first number of target symbols can be data information. The second number of target symbols is the OOK symbols or OFDM symbols occupied by the first 8 bits of source information. In this embodiment, the first processing process is performed on each bit bi in the first type of information, so that the first type of information can be converted into the fifth type of information. For example, the first processing step may use Manchester encoding.
