Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a signal receiving and sending method and device, namely a storage medium. Background Art

[0002] The signal generation and transmission method in the New Radio (NR) system requires the terminal equipment to have the ability to independently generate and send signals. The terminal equipment needs to have a stable power supply to support complex signal processing such as modulation and coding, as well as the electromagnetic wave transmission of RF devices.

[0003] In order to solve the problem that all IoT devices are powered by batteries, which require regular charging or battery replacement, resulting in manpower and material costs, the 3rd Generation Partnership Project (3GPP) has newly defined a type of device - Ambient-Internet of Things (A-IoT).

[0004] However, some A-IoT devices have no or only limited energy storage capacity, no ability to actively communicate, and insufficient energy storage capacity to support their autonomous signal generation and transmission.

[0121] IoT devices are powered by batteries, so they need to be charged or replaced regularly, which results in a lot of manpower and material expenditures. To further reduce the cost of IoT devices and expand their application scope, 3GPP has newly defined A-IoT devices. A-IoT devices rely on wind, light, pressure, wireless signals and other sources in the environment to obtain energy, and are characterized by low energy consumption and low cost.

[0122] The signal generation and transmission methods in the New Radio (NR) system require the NR terminal / user equipment (UE) to have the ability to independently generate and send signals. The terminal equipment needs to have a stable power supply to support complex signal processing processes such as modulation and coding, as well as the electromagnetic wave transmission of RF devices.

[0123] In the NR system, the NR terminal transmits signals based on the scheduling of the base station: the base station sends control information to the NR terminal, instructing the NR terminal on which physical transmission resources to send signals; the NR terminal generates signals according to the specified signal structure and sends signals on the specified time-frequency resources according to the instructions of the base station. The energy required for the NR terminal to generate and send RF signals comes from the battery it carries. Therefore, the transmitted signal and the received signal are independent of each other in energy, and usually have a certain time interval in time, so as to meet the processing time requirements of the complex received signal decoding and transmitted signal generation process.

[0124] However, some A-IoT devices have no or only limited energy storage capacity, no ability to actively communicate, and insufficient energy storage capacity to support their autonomous signal generation and transmission. In other words, the signal structure and signal transmission process in the NR system cannot be directly applied to the communication scenarios of A-IoT devices and cannot meet the communication needs of A-IoT devices. The current communication technology for A-IoT devices in the NR system is still blank.

[0125] In addition, in the NR transmission mechanism, the transmission of reference signals or signaling such as synchronization, positioning, data scheduling, and initial access is independent of each other. In the application scenario of A-IoT devices, there is usually a high device connection density. If the existing mechanism is used, it will cause transmission delay.

[0126] Different A-IoT device types have different energy storage and signal transmission capabilities. If independent signal transmission methods are designed for the three types of devices, time delay and transmission resource overhead will be generated.

[0127] In response to the above-mentioned problems existing in the related technology, the embodiments of the present application provide a signal receiving and sending method, device and storage medium, which triggers the first device to communicate with the second device and / or triggers the first device to perform a first operation through a first signal sent by a second device carrying information corresponding to a first device of at least one device type. The characteristics of devices with limited storage capacity and independent signal generation capacity such as A-IoT devices in terms of energy storage and signal transmission are fully considered, and a communication solution for devices with limited storage capacity and independent signal generation capacity such as A-IoT devices is implemented, which fills the gap in communication technology for A-IoT devices in the current NR system, and at the same time minimizes the complexity of signaling design as well as the resource overhead and delay of signaling transmission.

[0128] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0129] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0130] In the embodiments of the present application, "determine B based on A" means that the factor A should be considered when determining B. It is not limited to "B can be determined based on A alone", but should also include: "determine B based on A and C", "determine B based on A, C and E", "determine C based on A, and further determine B based on C", etc. In addition, it can also include taking A as a condition for determining B, for example, "when A meets the first condition, use the first method to determine B"; for another example, "when A meets the second condition, determine B", etc.; for another example, "when A meets the third condition, determine B based on the first parameter", etc. Of course, it can also be a condition that takes A as a factor in determining B, for example, "when A meets the first condition, use the first method to determine C, and further determine B based on C", etc.

Therefore, the time domain resources occupied by the information corresponding to the first devices of different device types in the first signal may be further informed by the protocol pre-defined or pre-configured method.

[0169] ⑤ Frequency domain resources occupied by the information carried in the first signal. Furthermore, the frequency domain resources occupied by the information corresponding to different device types may be the same or different. Therefore, the frequency domain resources occupied by the information corresponding to the first devices of different device types in the first signal may be further informed by a protocol predefined or preconfigured manner.

[0170] Among them, the pre-configuration method can be a system message, a radio resource control (Radio Resource Control, RRC) message, a medium access control control element (Medium Access Control Control Element, MAC CE), a downlink control indication (Downlink Control Indication, DCI) and other messages sent by the second device, carrying the above-mentioned relevant content of the first signal.

[0171] The signal receiving method provided in the embodiment of the present application informs the first device of relevant information of the first signal in a predefined or preconfigured manner, such as the signal waveform corresponding to each information carried by the first signal, the occupied time-frequency resources, the order of constituting the first signal, the manner of constituting the first signal, etc., so that different numbers and types of first devices can receive the first signal, further improving the communication solution for devices with limited storage capacity and independent signal generation capability such as A-IoT devices, while reducing the complexity of signaling design as well as the resource overhead and latency of signaling transmission.

[0172] In some embodiments, when the first signal is used to trigger communication between the first device and the second device, the method further includes:

[0173] Based on the first signal, a response signal is sent to the second device, where the response signal includes response information of part or all of the information carried in the first signal.

[0174] Specifically, the first device receives a first signal sent by the second device, and in some cases, needs to provide feedback to the second device, that is, communicate with the second device, specifically including: based on the first signal sent by the second device, sending a response signal to the second device, the response signal including response information of part or all of the information carried in the first signal.

[0175] For example, the first signal carries reporting request information, and the reporting request information indicates that the first device reports data or control information. For example, the first signal contains positioning information, indicating that the first device sends and / or receives a positioning signal. This type of information often requires the first device to provide feedback to the second device, and of course the first device can independently choose whether to carry the corresponding response information in the response signal.

[0176] For example, if the first signal carries reporting request information and synchronization information, the first device can carry the response information of the reporting request information in the response signal, and for the synchronization information, the first device does not need to feed back the response information to the second device, and can complete the synchronization based on the timing information of the second device. For example, if the first signal carries energy collection information and positioning information, the first device can carry the response information of the positioning information in the response signal, and for the energy collection information, the first device can collect the energy of the first signal for subsequent signal processing and transmission, without feeding back the response information to the second device.

[0177] For another example, the first signal carries reporting request information, synchronization information and positioning information, but because the first device has no positioning requirements, the response signal only carries response information to the reporting request information.

[0178] The signal receiving method provided in the embodiment of the present application is that when the first device receives the first signal sent by the second device for triggering communication between the first device and the second device, the first device feeds back a response signal to the second device, wherein the response signal includes response information of part or all of the information carried in the first signal, further improving the communication scheme for devices with limited storage capacity and independent signal generation capability, such as A-IoT devices.

[0179] In some embodiments, sending a response signal to the second device includes:

[0180] The response signal is sent to the second device by at least one of backscattering, uplink transmission and sidelink transmission.

[0181] Specifically, the backscatter communication system usually consists of a reader with RF capability and a tag without RF capability. The reader sends a RF signal to the tag, and the RF signal electromagnetic wave reaches the surface of the tag antenna to form a reflected echo, i.e., a backscatter signal. By changing the impedance of the antenna, the tag can modulate information into the backscatter signal. The reader receives and reads the backscatter signal from the tag, and can obtain the information transmitted by the tag.

[0182] Some A-IoT devices do not have the ability to actively communicate and can only backscatter received signals, carrying information in the backscattered signals. In the A-IoT communication scenario, the tag is the A-IoT device, and the reader can be a base station, NR terminal, etc.

[0183] For the first device that has the ability to generate signals independently, a response signal is sent to the second device by at least one of backscattering, uplink transmission and side transmission, and the response signal is a backscattering signal, an uplink signal or a side transmission signal. For the first device that does not have the ability to generate signals independently, a response signal is sent to the second device by backscattering, and the response signal is a backscattering signal.

[0184] The signal receiving method provided in the embodiment of the present application is based on whether the first device has the ability to independently generate signals, and thus feeds back a response signal to the second device through at least one of backscattering, uplink transmission and side transmission, further improving the communication solution for devices with limited storage capacity and independent signal generation capability such as A-IoT devices.

[0185] In some embodiments, the first signal carries at least one of the following information:

[0187] second indication information used to instruct the first device to receive and / or send a positioning signal;

[0188] third indication information used to instruct the first device to report information;

[0189] information for authenticating the first device;

[0190] Information for verifying the security and integrity of data stored in the first device;

[0191] Activate information of the first device.

[0192] Specifically, in a scenario where a first device communicates with a second device, the first signal carries one or more pieces of information.

[0193] Such information often has an indication function. For example, the first indication information used to instruct the first device to start the initial access process can be called initial access information. For example, the second indication information used to instruct the first device to receive and / or send a positioning signal can be called positioning information. For example, the indication information used to instruct the first device to report information, including reporting data and control information, can be called reporting request information.

[0194] For another example, information for authenticating the identity of the first device may be referred to as authentication information. For example, information for verifying the security and integrity of data stored in the first device may be referred to as integrity verification information. For example, information for activating the first device may wake up the first device from a non-working state or a state with lower power consumption to start sending and receiving data.

[0195] Optionally, the first signal also carries at least one of the following information: identification (ID) information of the first device; group identification information of the group to which the first device belongs. The first signal carries the identification information of the first device, or the identification information of the target device, which may be an ID number, indicating that the first device corresponding to the identification information needs to receive and / or respond to the first signal. The first signal carries the group identification information, indicating that all first devices in the identification group need to receive and / or respond to the first signal.

[0196] The signal receiving method provided in the embodiment of the present application, in a scenario where the first device and the second device need to communicate, carries information related to various mechanisms such as data transmission, initial access, mobility management, and positioning in the first signal, further improving the communication solution for devices with limited storage capacity and independent signal generation capabilities such as A-IoT devices, while reducing the complexity of signaling design as well as the resource overhead and latency of signaling transmission.

[0197] In some embodiments, sending a response signal to the second device includes:

[0201] The response signal is sent on discontinuous time domain resources and discontinuous frequency domain resources.

[0202] Specifically, the first device sends a response signal to the second device, and the transmission resources used by the response signal may be continuous / discontinuous in the frequency domain / time domain.

[0203] When continuous time domain resources are used, one or more information included in the response signal may be transmitted in the time domain in different orders.

The three response information are divided into two sub-segments in the time domain for transmission. The two sub-segments respectively include one response information {1} and two response information {2,3}.

[0205] When continuous frequency domain resources are used, one or more information included in the response signal may be transmitted in the frequency domain in different orders.

The information sequence can also be {2, 1}.

[0206] When discontinuous frequency domain resources are used, one or more information included in the response signal may be transmitted in the frequency domain in different orders and combinations. Figure 5is a schematic diagram of a discontinuous response signal in the time domain provided by an embodiment of the present application, such as Figure 5 As shown, the response signal includes three different response information: response 1 and response 2. The two response information are divided into two sub-segments in the time domain for transmission. The two sub-segments respectively include one response information {1} and one response information {2}.

[0207] The signal receiving method provided in the embodiment of the present application supports the first device to feedback a response signal on continuous / discontinuous time domain / frequency domain resources in a communication scenario with the second device, further improving the communication solution for devices with limited storage capacity and independent signal generation capabilities such as A-IoT devices, while providing a certain flexibility for the scheduling of transmission resources.

[0208] In addition to the scenario where the first device communicates with the second device and feeds back a response signal to the second device, there is another scenario where, after receiving the first signal, the first device performs a first operation based on the information carried in the first signal and does not provide any feedback to the second device, such as synchronization, energy storage, etc. In actual implementation, the first signal may often carry a variety of information, including both information that needs to be fed back by the first device and information that does not need to be fed back by the first device.

The first device completes synchronization with the second device based on such information carried in the first signal. The synchronization in the embodiment of the present application can be fine synchronization or coarse synchronization.

[0212] In some embodiments, the first operation includes:

[0213] The energy of the first signal is acquired based on the fifth indication information carried in the first signal and used to indicate the energy of the first signal and / or the sixth indication information used to instruct the first device to acquire the energy of the first signal.

[0214] Specifically, corresponding to the energy storage scenario, the first signal carries at least fifth indication information for indicating the energy of the first signal and / or sixth indication information for instructing the first device to obtain the energy of the first signal. Based on the fifth indication information and / or the sixth indication information, the first device obtains the energy of the first signal.

[0298] receiving the response signal on discontinuous time domain resources and continuous frequency domain resources; or,

[0299] The response signal is received on discontinuous time domain resources and discontinuous frequency domain resources.

[0300] Specifically, the second device receives a response signal sent by the first device, and the transmission resources used by the response signal may be continuous / discontinuous in the frequency domain / time domain.

[0301] When continuous time domain resources are used, one or more information contained in the response signal can be transmitted in the time domain in different orders. Figure 2 .

[0302] When discontinuous time domain resources are used, one or more information contained in the response signal can be transmitted in the time domain in different orders and combinations. Figure 3 .

[0303] When continuous frequency domain resources are used, one or more information contained in the response signal can be transmitted in the frequency domain in different orders. Figure 4 .

[0304] When discontinuous frequency domain resources are used, one or more information contained in the response signal can be transmitted in the frequency domain in different orders and combinations. Figure 5 .

[0305] In a scenario where transmission resources are discontinuous, multiple response information contained in the response signal can be divided into different sub-segments. A sub-segment contains one or more response information. The transmission order of different sub-segments can be changed, and the transmission order of different response information in a sub-segment can also be changed.

[0306] The signal receiving method provided in the embodiment of the present application supports the first device to feedback a response signal on continuous / discontinuous time domain / frequency domain resources in a communication scenario with the second device, further improving the communication solution for devices with limited storage capacity and independent signal generation capabilities such as A-IoT devices, while reducing signaling transmission delay and providing a certain flexibility for the scheduling of transmission resources.

[0307] In addition to the scenario where the first device communicates with the second device and feeds back a response signal to the second device, there is another scenario where, after receiving the first signal, the first device performs a first operation based on the information carried in the first signal and does not provide any feedback to the second device, such as synchronization, energy storage, etc. In actual implementation, the first signal may often carry a variety of information, including both information that needs to be fed back by the first device and information that does not need to be fed back by the first device.

[0308] In some embodiments, the first signal carries timing information of the second device and / or fourth indication information for instructing the first device to obtain the timing information, and the first operation includes synchronization with the second device.

[0309] Specifically, for the synchronization scenario, the first signal carries at least the timing information of the second device, and / or fourth indication information for instructing the first device to obtain the timing information of the first device. The first device completes synchronization with the second device based on such information carried in the first signal. The synchronization in the embodiment of the present application may be fine synchronization or coarse synchronization.

[0310] In some embodiments, the first signal carries fifth indication information for indicating energy of the first signal and / or sixth indication information for instructing the first device to acquire energy of the first signal, and the first operation includes acquiring energy of the first signal.

[0311] Specifically, corresponding to the energy storage scenario, the first signal carries at least fifth indication information for indicating the energy of the first signal and / or sixth indication information for instructing the first device to obtain the energy of the first signal, so that the first device obtains the energy of the first signal based on the fifth indication information and / or the sixth indication information.

[0312] The first signal is a radio frequency signal. When the first device has energy storage capability, the energy of the radio frequency signal is obtained and can be used for subsequent signal transmission and reception.

[0313] Optionally, no matter whether the first device needs to feed back the first signal to the second device or does not need to feed back the first signal, the first signal may also carry at least one of the following information: identification information of the first device; group identification information of the group to which the first device belongs. The first signal carries the identification information of the first device, or the identification information of the target device, and the identification information may be an ID number, indicating that the first device corresponding to the identification information needs to receive and / or respond to the first signal. The first signal carries the group identification information, indicating that all first devices in the identification group need to receive and / or respond to the first signal.

[0314] The signal sending method provided in the embodiment of the present application supports the case where the first signal carries information that does not require feedback from the first device, and the first device independently indicates the corresponding operation according to the information carried in the first signal. This further improves the communication scheme for devices with limited storage capacity and independent signal generation capabilities such as A-IoT devices in scenarios such as synchronization and energy storage, while reducing the complexity of signaling design as well as the resource overhead and latency of signaling transmission.

[0315] In some embodiments, sending the first signal to the first device includes:

[0316] The first signal is sent to the first device in the form of a bit stream.

[0317] Specifically, the first signal may be in the form of a bit stream. Different bit fields correspond to different information, which together constitute a sequence of information carried in the first signal.

[0318] In some embodiments, sending the first signal to the first device includes:

[0319] sending the first signal on continuous time domain resources and continuous frequency domain resources; or,

[0320] sending the first signal on continuous time domain resources and discontinuous frequency domain resources; or,

[0321] sending the first signal on discontinuous time domain resources and continuous frequency domain resources; or,

[0322] The first signal is sent on discontinuous time domain resources and discontinuous frequency domain resources.

[0323] Specifically, the transmission resources used to send the first signal may be continuous / discontinuous in the frequency domain / time domain.

[0324] When continuous time domain resources are used, one or more information contained in the first signal may be transmitted in the time domain in different orders. Figure 6 .

[0325] When discontinuous time domain resources are used, one or more information contained in the first signal can be transmitted in the time domain in different orders and combinations. Figure 7 .

[0326] When continuous frequency domain resources are used, one or more information contained in the first signal may be transmitted in the frequency domain in different orders. Figure 8 .

[0327] When discontinuous frequency domain resources are used, one or more information contained in the first signal can be transmitted in the frequency domain in different orders and combinations. Fig. 9 .

[0328] In a scenario where transmission resources are discontinuous, the multiple information contained in the first signal can be divided into different sub-segments. A sub-segment contains one or more information. The transmission order of different sub-segments can be changed, and the transmission order of different information in a sub-segment can also be changed.

[0329] The signal sending method provided in the embodiment of the present application supports the first device to receive signals on continuous / discontinuous time domain / frequency domain resources, further improves the communication solution for devices with limited storage capacity and independent signal generation capabilities such as A-IoT devices, and at the same time provides a certain flexibility for the scheduling of transmission resources.
