Description

Information sending and receiving methods, devices and communication systems Technical Field

[0001] The embodiments of this application relate to the field of communication technology. Background Technology

[0002] Digital mobile communication has evolved through 2G, 3G, 4G, and now 5G, effectively meeting people's needs in voice communication, digital mobile communication, and mobile broadband networking. However, with social and economic development, the demand for Internet of Things (IoT) communication is gradually emerging. To meet the needs of IoT communication, 3GPP (3rd Generation Partnership Project) has defined a series of IoT technology standards, including MTC (Machine-Type Communication), NB-IoT (Narrow Band Internet of Things), and RedCap (Reduced Capability).

[0003] While existing IoT technology standards have met the requirements of low cost, low power consumption, and massive connectivity for IoT terminal devices, there are still many scenarios where IoT communication needs cannot be met using these standards. These include extreme working environments that hinder the maintenance of IoT terminal devices, and the need for extremely small size and low cost terminal devices. How 3GPP can support these IoT terminal device requirements within cellular systems is a problem that needs to be addressed.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application. Summary of the Invention

[0005] The inventors discovered that RFID (Radio Frequency Identification) technology is a widely used communication technology that can identify specific targets and read / write related data in a non-contact manner. The advantages of RFID systems include low tag cost and small size, making them frequently used in various applications such as logistics information collection, retail, libraries, and identity verification. One disadvantage of RFID systems is the limited information reading range (based on the wireless signal communication range) of RFID tags. Using manual handheld tag readers can result in high labor costs, which may be the main expense. Using dedicated RFID gateways to read and manage RFID tags requires significant deployment costs. Furthermore, the simple logical architecture of RFID systems makes it difficult to effectively coordinate with interference in radio wave transmission, resulting in generally low system capacity and spectrum utilization efficiency.

[0006] Compared to RFID systems, 3GPP's 5G systems support tag-based terminal devices, allowing for the reuse of existing base stations and leveraging existing cellular networks to support industry applications based on this type of terminal, thereby effectively reducing deployment and usage costs. 3GPP's 5G systems can provide reliable authentication, network coordination, and accurate and stable terminal device management mechanisms, and can also optimize the network to improve system capacity and spectrum utilization efficiency.

[0007] As a new type of IoT terminal in 5G systems, Ambient IoT devices (AIoT devices) are severely limited in cost. Their capabilities are significantly weaker than those of ordinary smartphones and other IoT devices supported by existing cellular mobile communication systems. For example, AIoT devices have limited processing power and stored energy for communication, and the mechanisms in existing 5G systems for transmitting uplink signals under network control cannot be reused. How AIoT devices can utilize their limited processing power and stored energy to transmit uplink signals under network control is a problem that needs to be solved.

[0049] RFID systems are solutions for the large-scale, low-cost Internet of Things (IoT) terminal devices. RFID systems have wide applications. The advantages of RFID systems include low tag cost and low price. RFID tags are small, with fewer restrictions on the size and material of the items they can be used with, making them easy to apply to various item management and tracking scenarios. Although RFID tags are inexpensive, the deployment and usage costs of RFID systems are higher than wide-area commercial networks. In terms of deployment, RFID systems are typically deployed locally, with dedicated networks, making it difficult to effectively amortize deployment costs. In terms of usage, if a manual handheld tag reader solution is used, labor costs may become the main operating expense and are difficult to reduce; if dedicated RFID ports or gateways are used for reading and management, deployment costs will increase significantly. Furthermore, the simple logical architecture of RFID systems and loose wireless resource management, such as the difficulty in effectively coordinating interference in radio wave transmission, generally result in lower system capacity and spectrum utilization efficiency.

[0050] Compared to existing RFID systems, leveraging existing commercial mobile cellular networks (such as LTE and 5G NR systems) to support industry applications requiring tag-based IoT devices can effectively reduce deployment costs, thereby lowering the barrier to entry for this type of IoT device deployment. Furthermore, existing commercial mobile cellular networks (such as LTE and 5G NR systems) offer significantly better network security and wireless resource management than existing RFID systems. Taking 5G systems as an example, 5G can provide high-security authentication, network coordination, and accurate and stable terminal device management mechanisms, effectively reducing labor costs and thus lowering the overall cost of using this type of IoT. It can also optimize the network to improve system capacity and spectrum utilization efficiency. This reduction in deployment and usage costs can effectively promote the application of tag-based IoT devices in business management and industrial manufacturing, accelerate the digitalization process of related industries, improve production efficiency, and ultimately contribute more effectively to social development.

[0051] The following examples illustrate the scenarios of embodiments of this application, but this application is not limited thereto.

[0052] Figure 1 is a schematic diagram of a communication system according to an embodiment of this application, Figure 2 is another schematic diagram of a communication system according to an embodiment of this application, and Figure 3 is yet another schematic diagram of a communication system according to an embodiment of this application. Figures 1 to 3 schematically illustrate the situation using terminal devices and network devices as examples.

[0053] As shown in Figure 1, network devices can communicate directly with AIoT devices, sending signals directly to or receiving signals directly from AIoT devices. As shown in Figure 2, network devices can also send signals to or receive signals from AIoT devices through intermediate nodes. As shown in Figure 3, network devices can also send signals to AIoT devices or receive signals from AIoT devices via auxiliary nodes with the assistance of auxiliary nodes.

[0054] In the above examples, intermediate nodes can be terminal devices, UEs, or network nodes, such as relays, IAB nodes, repeaters, etc., and this application is not limited to these. Intermediate nodes have the function of communicating with the network devices in Figure 2, and at least have the ability to send signals to and / or receive signals from AIoT devices. Auxiliary nodes can be terminal devices, UEs, or network nodes, such as relays, IAB nodes, repeaters, etc., and this application is not limited to these. Auxiliary nodes have the function of communicating with the network devices in Figure 3, and at least have the ability to send signals to and / or receive signals from AIoT devices. The signals sent to and received from AIoT devices as described here conform to the specifications and descriptions of AIoT devices in communication standard protocols.

[0055] In the embodiments of this application, the network device sending signals / information / configurations to the AIoT device, or the AIoT device receiving signals / information / configurations from the network device, can be done in several ways: the network device directly sends the signal to the AIoT device, which then receives it; the network device sends the signal to the AIoT device via an intermediate node, which then receives it; the network device sends the signal to the AIoT device with the assistance of an auxiliary node, which then receives it; or the network device sends the signal to the AIoT device through other methods, which then receives it. Unless otherwise specified, this application is not limited to these methods.

[0056] In the embodiments of this application, the AIoT device sending signals / information to the network device or the network device receiving signals / information from the AIoT device can be done in various ways: the AIoT device sends the signal and the network device receives it directly; the AIoT device sends the signal and the network device receives it via an intermediate node; the AIoT device sends the signal and the network device receives it with the help of an auxiliary node; or the AIoT device sends the signal and the network device receives it through other methods. Unless otherwise specified, this application is not limited to these methods.

[0057] As a new type of IoT terminal in 5G systems, tagged IoT devices are severely constrained by cost. Their hardware capabilities are significantly weaker than traditional terminal devices, such as smartphones and other IoT devices supported by existing cellular mobile communication systems. For example, tagged IoT devices have extremely limited processing power and storage resources, and may not support uplink signal transmission according to the resources configured for network equipment. Existing 5G systems' mechanisms for uplink signal transmission by terminal devices cannot be reused.

[0058] To address at least one of the aforementioned problems or other similar issues, the embodiments of this application will be described below with reference to the accompanying drawings and specific implementation details. The above content can be incorporated as part of the embodiments of this application and combined with one or more of the following embodiments.

[0059] In the embodiments of this application, unless otherwise specified, expressions such as "in the case of," "if," and "when" have the same meaning and can be interchanged; tag-type terminal devices are also referred to as "first devices," "terminals," or "AIoT devices," and network devices are also referred to as "second devices," "networks," or "reading devices." They can be network devices in the examples of Figures 1 to 3, intermediate nodes in the example of Figure 2, or auxiliary nodes in the example of Figure 3. For example, they can be readers or interrogators, etc.

[0060] In the embodiments of this application, uplink / downlink signal transmission and reception can be performed between the first device and the second device. Downlink can also be an R2D link (reader-to-device link) or an R2T link (reader-to-tag link), etc., while uplink can also be a D2R link (device-to-reader link) or a T2R link (tag-to-reader link), etc. This application is not limited to these.

[0061] First aspect of the embodiments

[0062] This application provides an information sending method, which will be described from the perspective of a terminal device.

[0063] Figure 4 is a schematic diagram of an information sending method according to an embodiment of this application. As shown in Figure 4, the method includes:

[0064] 401, The terminal device receives a first signal sent by the network device from a first resource; the first signal includes at least information related to a second resource, the second resource being used to carry a second signal that the network device configures / instructs / expects the terminal device to send;

[0065] 402, the terminal device sends a third signal to the network device in a third resource, wherein the third resource is included in the second resource; or the terminal device does not send information / signals in the second resource or the third resource.

[0066] It is worth noting that Figure 4 above is only an illustrative description of the embodiments of this application, but this application is not limited thereto. For example, the execution order between various operations can be appropriately adjusted, and other operations can be added or some operations can be removed. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description in Figure 4 above.

[0067] In the embodiments of this application, the terminal device is, for example, a tag-type terminal device in the scenarios shown in Figures 1 to 3, which may be referred to as other devices, such as a first device or an IoT device; the network device is, for example, a network device in the scenarios shown in Figures 1 to 3, an intermediate node in the scenario shown in Figure 2, or an auxiliary node in the scenario shown in Figure 3, which may also be referred to as other devices, such as a second device or a reader. For ease of explanation, this application uses a tag-type terminal device as the first device and a network device as the second device as an example for description.

[0068] In the embodiments of this application, unless otherwise specified, the first signal refers to a downlink signal, and the first resource refers to a downlink resource. The second signal refers to an uplink signal configured / indicated / expected by the network device to be sent by the terminal device, and the second resource refers to the uplink resource configured / indicated by the network device to the terminal device. The third signal refers to the uplink signal actually sent by the terminal device, and the third resource refers to the uplink resource actually used by the terminal device.

[0069] According to embodiments of this application, a terminal device sends a third signal to a network device in a third resource, wherein the third resource is included in the second resource; or the terminal device does not send information / signals in either the second or third resource. The third signal actually sent by the terminal device differs from the second signal configured / indicated / expected by the network device, or the terminal device does not send a signal in the second resource. Therefore, the terminal device does not perform uplink transmission according to the network device's configuration / scheduling / instructions. Tag-based terminal devices, based on their limited processing capabilities and stored energy, send uplink signals under the control of the network device.

[0070] In this embodiment, the terminal device can transmit a third signal on a third resource by backscattering a first waveform. The first waveform originates from a network device or a third-party device controlled by the network device, and the terminal device transmits uplink signals or information by backscattering the first waveform. For example, the terminal device adjusts its backscattering circuit to modulate the signal or information to be sent to the network device onto the first waveform, and then backscatters the modulated first waveform.

[0071] In some embodiments, the first waveform may be a continuous waveform (CW), a carrier waveform (CW), a backscattered / backscattering waveform, an uplink waveform, etc., and this application is not limited thereto.

[0072] In some embodiments, the first waveform can be a single-frequency signal waveform with constant envelope or a multi-frequency signal waveform. Furthermore, the first waveform can be continuous or discontinuous on the time axis.

[0073] In some embodiments, the terminal device can transmit a third signal on a third resource using a carrier signal it generates itself. For example, the terminal device modulates the signal or information intended for transmission to the network device onto a carrier signal and then transmits the modulated signal. This carrier signal can be a single-frequency signal waveform with a constant envelope or a multi-frequency signal waveform. Furthermore, the carrier signal can be continuous or discontinuous on the time axis.

[0074] In some embodiments, the first signal includes at least information related to the second resource, which is a signal and / or information sent by the network device to the terminal device, and may carry scheduling information, control information or triggering information for uplink signal or information transmission.

[0075] In addition, the first signal is used to carry at least one of the following: scheduling information / control information / trigger information / configuration information for uplink signal / information transmission, indication information / control information / trigger information for downlink signal / information reception, and data information sent by the network device to the terminal device.

[0076] For example, the first signal includes at least information related to the second resource, such as control, scheduling, or instruction information, commands, or signaling sent by the network device to the terminal device, which can be used to schedule, control, or trigger the terminal device to send the second signal desired by the network device, or to instruct or control the terminal device to receive downlink data.

[0077] For example, information related to the second resource can be carried in layer 1 (PHY layer) control signaling, for example, the network device sends the information to the terminal device through the layer 1 control channel and / or data channel; or, the information can be carried in higher layer control signaling, such as in MAC CE, for example, the network device can send the information to the terminal device in the form of service or protocol data units or sub-units.

[0078] In some embodiments, the information relating to the second resource includes at least one of the following: the start position of the second resource; the end position of the second resource; the duration of the second resource; and the length of the information / payload carried by the second signal. This application is not limited thereto, and may include other information, for example.

[0079] In some embodiments, the time-domain and / or frequency-domain resources used to carry a first signal transmitted by a network device are referred to as first resources; the time-domain and / or frequency-domain resources used to carry a second signal to be transmitted by a terminal device are referred to as second resources. In the embodiments of this application, the first resources and the second resources may be distributed at different positions on the time axis, or the first resources and the second resources may be resources that do not overlap in the time domain, or more than one first resource and / or second resource may be distributed on the time axis in a TDM (time-division multiplexing) manner.

[0080] In some embodiments, the second signal is carried on a second resource. The second signal is a signal and / or information that the terminal device expects to be sent by the network device. In some embodiments, the terminal device sends signals or information on the second resource according to the network device's scheduling / configuration / control, or sends signals or information as expected by the network device. In other embodiments, the terminal device does not send signals or information on the second resource according to the network device's scheduling / configuration / control, or the signals or information it sends are not expected by the network device.

[0081] In some embodiments, the third resource is a time-domain and / or frequency-domain resource used by the terminal device for transmitting the third signal; the third resource is included in the second resource in the time domain and / or frequency domain.

[0082] For example, the third resource is included in the second resource in the time domain, including at least: the duration of the third resource is less than or equal to the duration of the second resource; the start position of the third resource is not earlier than the start position of the second resource; the end position of the third resource is not later than the end position of the second resource; and the length of the information / load carried by the third signal sent by the terminal device is less than or equal to the length of the information / load carried by the second signal configured / indicated by the network device.

[0083] In some embodiments, the third signal carried on the third resource includes at least one of the following: a reference signal or a guiding signal; padding information / signal; NACK information / signal; error / exception information / signal; and at least a portion of the information / load of the second signal. This application is not limited thereto; for example, it may also carry other information / signals.

[0084] In some embodiments, the terminal device sends type indication information to the network device, the type indication information being used to indicate the type of one or more information / signals carried by the third signal.

[0085] For example, the type indication information may be carried at least in the header or subheader of the MAC PDU, or it may be carried in the control or data channel of the physical layer. This type indication information may indicate that the third signal includes one or more of the following: a reference signal or pilot signal, padding information / signals, NACK information / signals, error / abnormal information / signals, or at least a portion of the information / payload of the second signal.

[0086] In some embodiments, the terminal device sends an end / termination identifier to the network device, the end / termination identifier being used at least to indicate the end or termination of the third signal in the time domain. The end / termination identifier may indicate the end / termination of one or more of the following information / signals included in the third signal: a reference signal or pilot signal, padding information / signals, NACK information / signals, error / abnormal information / signals, and at least a portion of the information / load of the second signal.

[0087] For example, the end / termination indicator is located in the time domain after the information / signal carried by the third signal; the waveform / pattern carrying the end / termination indicator is different from the waveform / pattern of the information or load carried by the third signal, and / or the waveform / pattern carrying the end / termination indicator is determined at least by a standard predefined method.

[0088] In some embodiments, the terminal device sends length indication information to the network device, the length indication information being used at least to indicate the length of one or more information / signals carried in the third signal.

[0089] For example, the length indication information is carried at least through the header or subheader of the MAC PDU, or carried in the control or data channel of the physical layer. This length indication information may indicate the length or size of one or more of the following information / signals included in the third signal: reference or pilot signal, padding information / signal, NACK information / signal, error / abnormal information / signal, or at least a portion of the information / payload of the second signal.

[0090] In some embodiments, the third signal carries multiple types of information / signals; different types of information / signals are carried on different MAC PDUs or SDUs, or different types of information / signals are carried on the same MAC PDU or SDU.

[0091] In some embodiments, the duration of the information / load carrying at least a portion of the NACK information / signal and / or error / abnormal information / signal and / or second signal, and the duration of the third resource filling the information / signal, is at least the duration of the second resource.

[0092] For example, if the third signal includes two types of information / signals: a NACK message / signal and a padding message / signal, then the duration of the third resource actually used by the terminal device is equal to the duration of the second resource configured by the network device. As another example, if the third signal includes three types of information / signals: a NACK message / signal, an error / abnormality message / signal, and at least a portion of the second signal's information / payload, then the duration of the third resource actually used by the terminal device is equal to the duration of the second resource configured by the network device.

[0093] In some embodiments, at least a portion of the information / load of the NACK information / signal and / or error / abnormal information / signal and / or second signal, and the length of the padding information / signal is at least the length of the information / load carried by the second signal configured by the network device.

[0094] For example, if the third signal includes two types of information / signals: error / abnormal information / signals and padding information / signals, then the length of the information or payload carried in the third signal actually transmitted by the terminal device is equal to the length of the information or payload carried in the second signal configured by the network device. As another example, if the third signal includes four types of information / signals: carrying NACK information / signals, error / abnormal information / signals, at least a portion of the information / payload of the second signal, and padding information / signals, then the length of the information or payload carried in the third signal actually transmitted by the terminal device is equal to the length of the information or payload of the second signal configured by the network device.

[0095] The embodiments of this application have been illustrated above. The following will take the specific information / signal carried by the third signal as an example to illustrate various situations in which the terminal device sends / does not send the third signal.

[0096] In some embodiments, the terminal device does not transmit a third signal on the third resource, or the terminal device does not use the third resource to transmit a third signal.

[0097] For example, the terminal device may fail to receive the first signal sent by the network device, or the terminal device may be unable to execute the command carried by the first signal, or the terminal device may be unable to send the third signal (e.g., insufficient stored power). In these cases, the terminal device will not send the third signal on the third resource. If the network device does not receive the third signal sent by the terminal device on the configured second resource, it can take the next step according to the implementation algorithm, such as the network device retransmitting the first signal.

[0098] In some embodiments, the third signal includes a reference signal or a guiding signal, which is used for channel estimation and / or interference estimation. The reference signal or guiding signal includes a preamble, a midamble, or a postamble. The reference signal or guiding signal is carried in the control channel and / or data channel of the physical layer.

[0099] For example, the terminal device may transmit reference signals or pilot signals only on the third resource configured by the network device, without transmitting information bits; or, the third signal may only include reference signals or pilot signals. The reference signals or pilot signals may be preambles, midambles, or postambles. The network device can use the reference signals or pilot signals to perform channel estimation or interference estimation for subsequent actions, such as scheduling the transmission of the first signal.

[0100] The above has explained the reference signal or pilot signal. The following is a schematic explanation of the padding bit or padding signal.

[0101] In some embodiments, the third signal includes padding information / signals carried in a PDU or SDU at the MAC layer, or the padding information / signals are carried in a control channel and / or a data channel at the physical layer.

[0102] For example, the terminal device sends padding bits or padding signals on a third resource without sending information bits, or the third signal consists only of padding bits or padding signals.

[0103] In some implementations, the padding bits are carried in the PDU or SDU of the MAC layer, and the length of the padding bits is the information or payload length of the second signal configured by the network device; this length can be explicitly configured in the relevant information field of the MAC PDU, or it can be implicitly determined by the aforementioned information or payload length.

[0104] In some implementations, the duration of the transmitted waveform / signal of the fill signal in the time domain is the duration of the second resource.

[0105] In some implementations, the terminal device also sends indication information to the network device, indicating whether the third signal carries padding bits, or indicating the type of information / signal carried by the third signal. For example, in the header or subheader of a MAC PDU, a related information field indicates that the information carried by the MAC PDU is padding bits, or indicates that the type of information / signal carried is padding bits.

[0106] In some implementations, the padding signal is carried in a Layer 1 channel, such as a data channel. The duration of the padding signal in the time domain is the duration of the second resource. The waveform of the padding signal is distinct from the waveform of the information or payload carried in the third signal.

[0107] For example, signals can be distinguished by their pattern; for instance, the distribution of high and low levels over a given duration, or the proportion of high and low levels, can differentiate a signal from other information / load. Another example is the signal sequence; the waveform of the filler signal can be determined at least in a predefined manner. For example, communication standards define the waveform of the filler signal.

[0108] The above has explained the padding bits or padding signals. The following is a schematic explanation of the NACK information / signal.

[0109] In some embodiments, the third signal includes NACK information / signal, which is carried in a PDU or SDU at the MAC layer, or the NACK information / signal is carried in a control channel and / or data channel at the physical layer.

[0110] For example, a terminal device sends a third signal to a network device on a third resource, the third signal including at least a NACK message / signal. The NACK message / signal is used to indicate at least that the terminal device failed to successfully receive a first signal sent by the network device, or that the terminal device cannot execute the command carried by the first signal, or that the terminal device cannot send a second signal as expected by the network device, for example, due to insufficient stored power.

[0111] The third resource used to carry NACK information / signals is included within the second resource. For example, the duration of the third resource carrying NACK information / signals is shorter than the duration of the second resource. Another example is that, on the timeline, the start position of the third resource carrying NACK information / signals is no earlier than the start position of the second resource, and the end position of the third resource is no later than the end position of the second resource. Yet another example is that the length of the NACK information is less than the size of the information / payload carried by the second signal configured in the network device.

[0112] In some implementations, the NACK information / signal is carried in a MAC PDU or SDU, or via a Layer 1 control channel or data channel. For example, the NACK information / signal is represented using 1 bit.

[0113] In some implementations, the terminal device also sends indication information to the network device, indicating whether the third signal carries or contains NACK information / signal, or indicating the type of information / signal carried by the third signal. For example, indicating that the type of information / signal carried by the third signal is NACK information / signal.

[0114] For example, in the header or subheader of a MAC PDU, the relevant information fields indicate that the information carried by the MAC PDU is NACK information / signal, or that the type of information carried is NACK information / signal.

[0115] In some implementations, the waveform carrying the NACK information / signal is distinct from the waveform carrying the information or payload of a third signal. The waveform of the NACK information / signal can be determined at least in a predefined manner. For example, the communication standard predefines the waveform.

[0116] In some implementations, the time-domain location of the third resource carrying NACK information / signals is determined by network device configuration or a predetermined method. For example, the starting position of the third resource carrying NACK information / signals may be located at the starting position of the second resource.

[0117] In some implementations, the terminal device also sends a third signal end identifier to the network device to indicate the end / termination of the third signal transmission. For example, the terminal device sends a postamble or terminator to the network device to indicate the end of the third signal. The third signal end identifier is located in the time domain after the third resource carrying the NACK information / signal.

[0118] The waveform pattern of the third signal end marker can be determined in a predefined way, such as by communication standards. The network device detects this end marker to determine when to stop receiving the third signal. Using this implementation, even if the duration of the third resource is less than the end time of the second resource, the network device can still determine the end time of the third signal and not receive signals after the third resource, thereby reducing processing latency and power consumption without affecting reception performance.

[0119] In some implementations, the terminal device also sends padding bits or padding signals to the network device on a third resource, or the third signal includes NACK information / signal and padding bits / signal. For example, the number of NACK information bits plus the number of padding bits is the size of the information / payload carried by the second signal configured by the network device, or the duration of the third resource carrying NACK information + padding bits is the duration of the second resource configured by the network device. In some implementations, the padding bits are carried in a MAC PDU or SDU.

[0120] In some implementations, the NACK information bits and padding bits are carried in different MAC PDUs or SDUs. The terminal device also indicates the type of information carried by the PDU or SDU through the header or subheader of the MAC PDU, or the corresponding information fields of the header / subheader, such as padding bits or NACK information. The terminal device can also explicitly indicate the length of the padding bits through the header or subheader of the MAC PDU, or the corresponding information fields of the header / subheader; alternatively, the terminal device can implicitly indicate the length of the padding bits through the size of the information / payload carried by the second signal and the length of the NACK information / signal.

[0121] In other implementations, the NACK information bits and padding bits are carried in the same MAC PDU or SDU. The terminal device also indicates, through the header or subheader of the MAC PDU, or the corresponding information fields of the header / subheader, that the information carried by the PDU or SDU is NACK information + padding bits, or indicates that the type of information carried is NACK information + padding bits. The terminal device also indicates the length information of the NACK information and / or padding bits through the header or subheader of the MAC PDU, or the corresponding information fields of the header / subheader.

[0122] In some implementations, the padding signal is carried in a Layer 1 channel, such as a control channel and / or a data channel. The duration of the third resource carrying the NACK signal plus the padding signal is the duration of the second resource configured by the network device.

[0123] In some implementations, the temporal location of the third resource carrying the padding signal is determined by the network device configuration or by a predefined method. For example, the padding signal may be located after the NACK signal.

[0124] In some embodiments, the terminal device further sends indication information to the network device indicating that the signal carried by the third signal is a NACK signal plus a padding signal, or that the signal type is a NACK signal plus a padding signal. This indication information is carried at least through a Layer 1 control channel. In other embodiments, the terminal device further sends indication information to the network device indicating the length of the NACK signal and / or padding signal carried by the third signal. This indication information is carried at least through a Layer 1 control channel.

[0125] The above explains NACK information / signals (including NACK information / signals + padding bits / signals). The following is a schematic explanation of error / abnormal information / signals.

[0126] In some embodiments, the third signal includes error / abnormal information / signal, which is carried in a PDU or SDU at the MAC layer, or the error / abnormal information / signal is carried in a control channel and / or data channel at the physical layer.

[0127] For example, a terminal device sends a third signal to a network device on a third resource. The third signal includes at least error / abnormal information / signals. The error / abnormal information / signals are at least related to the reason why the terminal device failed to successfully receive the first signal sent by the network device, for example: the terminal device has insufficient power to demodulate and decode the first signal; or, the error / abnormal information / signals are at least related to the reason why the terminal device cannot execute the command carried in the first signal, for example: the command requires reading or writing to memory, but the memory is locked; or, the error / abnormal information / signals are at least related to the reason why the terminal device cannot send a second signal as expected by the network device, for example: the terminal device has insufficient power to send the second signal as required by the network device.

[0128] In some implementations, the error / abnormal information can be identified using error / abnormal codes or encoding. In some implementations, the communication standard uses one or more bits to predefine error / abnormal codes or encoding. For example, a 3-bit predefined error or abnormal code can be used: 000 indicates insufficient power, 001 indicates memory lock. The above is only an example and this application is not limited thereto.

[0129] A third resource for carrying error / abnormal information / signals is included within the second resource. For example, the duration of the third resource carrying error / abnormal information / signals is shorter than the duration of the second resource. As another example, on the timeline, the start position of the third resource carrying error / abnormal information / signals is no earlier than the start position of the second resource; the end position of the third resource is no later than the end position of the second resource. As yet another example, the length of the error / abnormal information is less than the size of the information / payload carried by the second signal configured in the network device.

[0130] In some implementations, the error / abnormal information / signal is carried in a MAC PDU or SDU, or through a Layer 1 control channel or data channel.

[0131] In some implementations, the terminal device also sends indication information to the network device, indicating whether the third signal carries or contains error / abnormal information / signals, or indicating the type of information / signals carried by the third signal. For example, indicating that the type of information / signals carried by the third signal is error / abnormal information / signals.

[0132] In some implementations, the header or subheader of the MAC PDU indicates, through relevant information fields, that the information carried by the MAC PDU contains error / abnormal information, or that the type of information carried is error / abnormal information / signal.

[0133] In some implementations, the waveform carrying error / abnormal information is distinct from the waveform carrying information or load in a third signal. The waveform of the error / abnormal information / signal can be determined at least in a predefined manner. For example, communication standards predefine the waveform.

[0134] In some implementations, the temporal location of the third resource carrying error / abnormal information / signals is determined through network device configuration or a predefined method. For example, the starting position of the third resource carrying error / abnormal information / signals may be located at the starting position of the second resource.

[0135] In some implementations, the terminal device also sends length information of the error / abnormal information to the network device. In some implementations, the length of the error / abnormal information carried by the MAC PDU is indicated by a related information field in the header or subheader of the MAC PDU. In other implementations, the length information is carried through a Layer 1 control channel or data channel.

[0136] In some implementations, the terminal device also sends a third signal end identifier to the network device to indicate the end / termination of the third signal transmission. For example, the terminal device sends a postamble or terminator to the network device to identify the end of the third signal. The position and waveform of the end identifier in the time domain can be referred to the description of the previous embodiments, and will not be repeated here.

[0137] In some implementations, the terminal device also sends padding bits or padding signals to the network device on a third resource, or the third signal includes error / abnormal information / signals and padding bits / signals. The number of error / abnormal information bits plus the number of padding bits is the size of the information / payload carried by the second signal configured by the network device, or the duration of the third resource carrying the error / abnormal information plus padding bits is the duration of the second resource configured by the network device.

[0138] In some implementations, the padding bits are carried in a MAC PDU or SDU.

[0139] In some implementations, error / exception information bits and padding bits are carried in different MAC PDUs or SDUs. The terminal device also indicates the type of information carried by the PDU or SDU through the header or subheader of the MAC PDU, or the corresponding information fields of the header / subheader, such as padding bits or error / exception information bits. The terminal device also explicitly or implicitly indicates the length information of the padding bits, as described in the foregoing embodiments, which will not be repeated here.

[0140] In other implementations, error / exception information bits and padding bits are carried in the same MAC PDU or SDU. The terminal device also indicates, through the header or subheader of the MAC PDU, or the corresponding information fields of the header / subheader, that the information carried by the PDU or SDU is error / exception information + padding bits, or indicates that the type of information carried is error / exception information + padding bits. The terminal device also indicates the length information of the error / exception information and / or padding bits through the header or subheader of the MAC PDU, or the corresponding information fields of the header / subheader.

[0141] In some implementations, the padding signal is carried in a Layer 1 channel, such as a control channel and / or a data channel. The duration of the third resource carrying the error / abnormal signal plus the padding signal is the duration of the second resource configured by the network device.

[0142] In some implementations, the temporal location of the third resource carrying the padding signal is determined by the network device configuration or by a predefined method. For example, the padding signal may be located after an error / abnormal signal.

[0143] In some embodiments, the terminal device further sends indication information to the network device, indicating that the signal carried by the third signal is an error / abnormal signal plus a padding signal, or that the signal type is an error / abnormal signal plus a padding signal. This indication information is carried at least through a Layer 1 control channel. In other embodiments, the terminal device further sends indication information to the network device, indicating the length of the error / abnormal signal and / or padding signal carried by the third signal. This indication information is carried at least through a Layer 1 control channel.

[0144] The above has explained the error / abnormal information / signal (including error / abnormal information / signal + padding bits / signal). The following is an illustrative explanation of at least a portion of the information / load of the second signal.

[0145] In some embodiments, the third signal includes at least a portion of the information / load of the second signal, wherein at least a portion of the information / load of the second signal is carried in a PDU or SDU of the MAC layer, or wherein at least a portion of the information / load of the second signal is carried in a control channel and / or a data channel of the physical layer.

[0146] For example, a terminal device sends a third signal to a network device on a third resource. This third signal at least includes a portion of the second signal, or the third signal carries a portion or incomplete portion of the second signal that the network device expects the terminal device to send. For instance, due to insufficient stored energy, the terminal device sends a portion or incomplete portion of the second signal to the network device based only on scheduling information / control information / trigger information / configuration information carried in the first signal.

[0147] The third resource used to carry a portion of the second signal is included within the second resource. For example, the duration of the third resource carrying a portion of the second signal is shorter than the duration of the second resource. As another example, on the timeline, the start position of the third resource carrying the second signal is no earlier than the start position of the second resource; the end position of the third resource is no later than the end position of the second resource. As yet another example, the length of the portion of the second signal carried in the third resource is less than the size of the information / payload carried by the second signal configured in the network device.

[0148] In some implementations, the terminal device also sends indication information to the network device, indicating whether the third signal carries (or contains) a portion of the second signal or an incomplete second signal, or indicating the type of information / signal carried by the third signal. For example, indicating that the type of information / signal carried by the third signal is a portion of the second signal or an incomplete second signal.

[0149] In some implementations, the header or subheader of the MAC PDU indicates, through a relevant information field, that the information carried by the MAC PDU is a partial second signal, or that the type of information carried is a partial second signal.

[0150] In some implementations, the terminal device also sends partial length information of the second signal to the network device. In some implementations, the length of the partial second signal carried by the MAC PDU is indicated by a related information field in the header or subheader of the MAC PDU. In other implementations, the length information is carried through a Layer 1 control channel or data channel.

[0151] In some implementations, the terminal device also sends a third signal end identifier to the network device to indicate the end / termination of the third signal transmission. For example, the terminal device sends a postamble or terminator to the network device to identify the end of the third signal. The position and waveform of the end identifier in the time domain can be referred to the description of the foregoing embodiments, and will not be repeated here.

[0152] In some implementations, the terminal device also sends padding bits or padding signals to the network device on a third resource, or the third signal includes a portion of the second signal and padding bits / signals. The number of bits in the portion of the second signal plus the number of padding bits is the size of the information / payload carried by the second signal configured by the network device, or the duration of the third resource carrying the portion of the second signal plus padding bits is the duration of the second resource configured by the network device.

[0153] In some implementations, the padding bits are carried in a MAC PDU or SDU.

[0154] In some implementations, a portion of the second signal and the padding bits are carried in different MAC PDUs or SDUs. The terminal device also indicates the type of information carried by the PDU or SDU through the header or subheader of the MAC PDU, or the corresponding information field of the header / subheader, such as padding bits or a portion of the second signal. The terminal device also explicitly or implicitly indicates the length information of the padding bits, as can be seen in the foregoing embodiments, which will not be repeated here.

[0155] In other embodiments, a portion of the second signal and padding bits are carried in the same MAC PDU or SDU. The terminal device also indicates, through the header or subheader of the MAC PDU, or the corresponding information fields of the header / subheader, that the information carried by the PDU or SDU is a portion of the second signal plus padding bits, or indicates that the type of information carried is a portion of the second signal plus padding bits. The terminal device also indicates the length information of the information / payload bits and / or padding bits through the header or subheader of the MAC PDU, or the corresponding information fields of the header / subheader.

[0156] In some implementations, the padding signal is carried in a Layer 1 channel, such as a control channel and / or a data channel. The duration of the third resource carrying the second signal plus the padding signal is the duration of the second resource configured by the network device.

[0157] In some implementations, the temporal location of the third resource carrying the padding signal is determined by the network device configuration or by a predefined method. For example, the padding signal may be located after a portion of the second signal.

[0158] In some embodiments, the terminal device further sends indication information to the network device, indicating that the signal carried by the second signal is a partial second signal plus a padding signal, or that the signal type is a partial second signal plus a padding signal. The indication information is carried at least through a Layer 1 control channel. In other embodiments, the terminal device further sends indication information to the network device, indicating the length of the partial second signal and / or padding signal carried by the third signal. The indication information is carried at least through a Layer 1 control channel.

[0159] The information included in the third signal has been explained above. The following is a schematic explanation of the combination of this information.

[0160] For example, a terminal device sends a third signal to a network device on a third resource. The third signal includes at least a NACK message / signal and an error / abnormal message / signal, or a NACK message / signal and a portion of a second signal, or an error / abnormal message / signal and a portion of a second signal, or a NACK message / signal, an error / abnormal message / signal, and a portion of a second signal.

[0161] The third resource used to carry the third signal (the aforementioned information / signal) is included within the second resource. For example, the duration of the third resource carrying the third signal is shorter than the duration of the second resource. As another example, on the timeline, the start position of the third resource carrying the aforementioned information / signal is no earlier than the start position of the second resource; the end position of the third resource is no later than the end position of the second resource. As yet another example, the length of the information / payload carried in the third signal is less than or equal to the size of the information / payload carried by the second signal configured in the network device.

[0162] In some implementations, the terminal device also sends indication information to the network device, indicating the type of the third signal bearer information / signal, such as the bearer information / signal type being NACK information / signal and error / abnormal information / signal, or NACK information / signal and part of a second signal, or error / abnormal information / signal and part of a second signal, or NACK information / signal, error / abnormal information / signal and part of a second signal. In some implementations, the type of information carried by the MAC PDU is indicated by a related information field in the header or subheader of the MAC PDU.

[0163] In some implementations, the terminal device also sends length information of the third signal to the network device. In some implementations, the length of the third signal carried by the MAC PDU is indicated by a related information field in the header or subheader of the MAC PDU. In other implementations, the length information is carried through a Layer 1 control channel or data channel.

[0164] In some implementations, the terminal device also sends a third signal end identifier to the network device to indicate the end / termination of the third signal transmission. For example, the terminal device sends a postamble or terminator to the network device to identify the end of the third signal. The time-domain position and waveform of the end identifier can be referred to the description of the foregoing embodiments, and will not be repeated here.

[0165] In some implementations, the terminal device also sends padding bits or padding signals to the network device on a third resource. For example, the third signal may include NACK information / signals and error / abnormal information / signals along with padding bits / signals; or, NACK information / signals and a portion of the second signal along with padding bits / signals; or, error / abnormal information / signals and a portion of the second signal along with padding bits / signals; or, NACK information / signals and error / abnormal information / signals and a portion of the second signal along with padding bits / signals. The number of bits in the aforementioned information / signals plus the number of padding bits represents the size of the information / payload carried by the second signal configured by the network device, or the duration of the third resource carrying the aforementioned information / signals plus padding bits represents the duration of the second resource configured by the network device.

[0166] In some implementations, the padding bits are carried in a MAC PDU or SDU.

[0167] In some implementations, the bits carrying the aforementioned information / signal and the padding bits are carried in different MAC PDUs or SDUs. The terminal device also indicates the type of information carried by the PDU or SDU through the header or sub-header of the MAC PDU, or the corresponding information field of the header / sub-header, for example, the type is padding bits or one of the aforementioned information / signals. The terminal device also explicitly or implicitly indicates the length information of the padding bits, as can be referred to in the foregoing embodiments, and will not be repeated here. The terminal device also indicates the length information of the padding bits through the header or sub-header of the MAC PDU, or the corresponding information field of the header / sub-header.

[0168] In other embodiments, the bits of the aforementioned information / signal and the padding bits are carried in the same MAC PDU or SDU. The terminal device also indicates, through the header or subheader of the MAC PDU, or the corresponding information field of the header / subheader, that the information carried by the PDU or SDU is one of the aforementioned information / signals plus padding bits, or indicates that the type of information carried is one of the aforementioned information plus padding bits. The terminal device also indicates, through the header or subheader of the MAC PDU, or the corresponding information field of the header / subheader, the length information of one of the aforementioned information / signals and / or the padding bits.

[0169] In some implementations, the padding signal is carried in a Layer 1 channel, such as a control channel and / or a data channel. The duration of the third resource carrying one of the aforementioned information / signals plus the padding signal is the duration of the second resource configured by the network device.

[0170] In some implementations, the temporal location of the third resource carrying the padding signal is determined by the network device configuration or by a predefined method. For example, the padding signal may be located after one of the aforementioned information / signals.

[0171] In some embodiments, the terminal device also sends indication information to the network device to indicate the signal type carried by the third signal. For example, the indication information is carried at least through a Layer 1 control channel. In other embodiments, the terminal device also sends indication information to the network device to indicate the length of one of the aforementioned information / signals and / or the padding signal. The indication information is carried at least through a Layer 1 control channel.

[0172] The above illustrations illustrate various combinations of information / signals in this application. This application is not limited to these; combinations of information not explicitly given in the above embodiments can also be used. These contents can be reasonably deduced and are therefore all within the scope of the embodiments of this application.
