Abstract
Description

Therefore, before obtaining energy, zero-power terminals are in a "power-off" state, i.e., offline. Furthermore, for zero-power communication systems, network deployment may be in an isolated coverage manner, rather than a full coverage approach, so zero-power terminals will be offline due to the lack of network coverage.

When a zero-power terminal is powered and enters the coverage area of a zero-power network, it will communicate with the network side.

[0064] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies of the embodiments of this application are described below. The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.
[0065] Zero-power communication technology principle
[0066] Zero-power communication employs energy harvesting and backscatter communication technologies. A zero-power communication system consists of network equipment and zero-power terminals, such as... Figure 2 As shown in the diagram, the network device is used to send power signals (i.e., radio waves), downlink communication signals, and receive backscattered signals from the zero-power terminal. As an example, the zero-power terminal includes an energy harvesting module, a backscattered communication module, and a low-power computing module. Furthermore, the zero-power terminal may also have a memory and / or sensors. The memory stores basic information (such as item identification), and the sensors acquire sensor data such as ambient temperature and humidity.
[0067] The following section provides further explanation of the key technologies for zero-power communication.
[0068] (1) Power Harvesting
[0069] Figure 3 It is a schematic diagram of energy harvesting, such as Figure 3 As shown, the energy harvesting module harvests electromagnetic wave energy from space based on the principle of electromagnetic induction, thereby obtaining the energy required to drive the zero-power terminal and enabling the driving of load circuits (such as low-power computing modules and sensors). Therefore, the zero-power terminal does not require a traditional battery, achieving battery-free communication.
[0070] As an example, the energy harvesting module refers to the radio frequency energy harvesting module, which can harvest the energy carried by radio waves in space, thereby realizing the harvesting of electromagnetic wave energy in space.
[0071] (2) Back Scattering
[0072] Figure 4 This is a schematic diagram of backscatter communication, such as... Figure 4 As shown, the zero-power terminal receives wireless signals sent by the network device (i.e., Figure 4 The information transmission process, which modulates the wireless signal (using the carrier wave in the antenna), that is, loading the information to be transmitted onto the wireless signal and radiating the modulated signal from the antenna, is called backscatter communication.
[0073] Backscatter communication and load modulation are inextricably linked; load modulation is a commonly used method for loading information in zero-power terminals. Load modulation adjusts and controls the circuit parameters of the zero-power terminal's oscillation circuit according to the data flow's rhythm, causing a change in the terminal's impedance and / or phase, thus completing the modulation process. Load modulation techniques mainly include resistive load modulation and capacitive load modulation.
[0074] like Figure 5 As shown, in resistive load modulation, a resistor is connected in parallel with the load, called the load modulation resistor. This resistor is switched on or off based on the control of the binary data stream. The switching of the resistor causes a change in the circuit voltage, thus realizing amplitude-shift keying (ASK) modulation, that is, signal modulation is achieved by adjusting the amplitude of the backscattered signal from the zero-power terminal. Similarly, in capacitive load modulation, a capacitor is connected in parallel with the load, called the load modulation capacitor. This capacitor replaces the... Figure 5 The medium-load modulation resistor can change the circuit resonant frequency by switching the capacitor on and off, thus realizing frequency keying modulation (FSK), that is, the signal is modulated by adjusting the operating frequency of the backscattered signal of the zero-power terminal.
[0075] As can be seen, zero-power terminals modulate the incoming signal using load modulation to achieve backscatter communication. Therefore, zero-power terminals have the following significant advantages: First, they do not actively transmit signals, thus eliminating the need for complex RF links such as power amplifiers and RF filters. Second, they do not need to actively generate high-frequency signals, thus eliminating the need for high-frequency crystal oscillators. Third, because they utilize backscatter communication, the transmission process does not consume the terminal's own energy.
[0076] Encoding methods for zero-power communication
[0077] Data transmitted by zero-power terminals can be represented by binary "1" and "0" using different code forms. Radio Frequency Identification (RFID) systems typically use one of the following encoding methods: Non-Return-to-Zero (NRZ) encoding, Manchester encoding, Unipolar RZ encoding, Differential Biphasic (DBP) encoding, Miller encoding, and Differential encoding. Representing binary "1" and "0" using different code forms can also be understood as using different pulse signals to represent 0 and 1. The following explains several numbering methods.
[0078] (1) Reverse Non-Return-to-Zero Encoding
[0079] Inverse non-return-to-zero encoding uses a high level to represent a binary "1" and a low level to represent a binary "0", such as... Figure 6 As shown.
[0080] (2) Manchester encoding
[0081] Manchester encoding is also known as split-phase encoding. In Manchester encoding, the value of a bit is represented by the level change (rising / falling) over half a bit cycle. A negative transition over half a bit cycle represents a binary "1", and a positive transition over half a bit cycle represents a binary "0", such as... Figure 7 As shown.
[0082] Manchester coding, when employing carrier load modulation or backscatter modulation, is typically used for data transmission from zero-power terminals to network devices because it facilitates the detection of data transmission errors. This is because a "no change" state is not allowed within the bit length. When multiple zero-power terminals simultaneously transmit data bits with different values, the received rising and falling edges cancel each other out, resulting in a continuous carrier signal throughout the entire bit length. Since this state is not allowed, network devices can use this error to determine the specific location of collisions.
[0083] (3) Unipolar return-to-zero coding
[0084] In unipolar return-to-zero encoding, a high level during the first half-bit cycle represents a binary "1", while a low level signal throughout the entire bit cycle represents a binary "0", such as... Figure 8 As shown. Unipolar return-to-zero encoding can be used to extract bit synchronization signals.
[0085] (4) Differential biphase coding
[0086] In differential biphase coding, any edge within half a bit cycle represents a binary "0", while the absence of an edge represents a binary "1", such as... Figure 9 As shown. Furthermore, the level is inverted at the beginning of each bit cycle. Therefore, the bit clock is relatively easy to reconstruct for the receiver.
[0087] (5) Miller coding
[0088] Miller encoding uses any edge within half a bit cycle to represent a binary "1", while a constant level in the next bit cycle represents a binary "0". A level alternation occurs at the beginning of a bit cycle, such as... Figure 10 As shown. Therefore, bit ticks are relatively easy to reconstruct for the receiver.
[0089] (6) Differential coding
[0090] In differential coding, each binary "1" to be transmitted causes a change in the signal level, while for a binary "0", the signal level remains unchanged.
[0091] Classification of zero-power terminals
[0092] Based on the energy source and usage method of zero-power terminals, zero-power terminals can be divided into the following types:
[0093] (1) Passive zero-power terminal
[0094] Zero-power terminals do not require an internal battery. When a zero-power terminal is near a network device, it falls within the near-field range of the network device's antenna radiation. Therefore, the terminal's antenna generates an induced current through electromagnetic induction. This induced current drives the terminal's low-power computing module (i.e., low-power chip circuitry) to perform demodulation of forward link signals and modulation of backward link signals. For backscatter links, the zero-power terminal uses backscattering to transmit signals.
[0095] It can be seen that the passive zero-power terminal does not require a built-in battery to drive either the forward or reverse link, making it a truly zero-power terminal.
[0096] Since passive zero-power terminals do not require batteries, their radio frequency circuits and baseband circuits are very simple. For example, they do not require low-noise amplifiers (LNAs), power amplifiers (PAs), crystal oscillators, ADCs, etc. Therefore, they have many advantages such as small size, light weight, low price, and long service life.
[0097] (2) Semi-passive zero-power terminal
[0098] Semi-passive zero-power terminals do not have conventional batteries installed, but they can use an energy harvesting module to collect radio wave energy and store the harvested energy in an energy storage unit (such as a capacitor). After obtaining energy, the energy storage unit can drive the low-power computing module (i.e., low-power chip circuit) of the zero-power terminal to perform tasks such as demodulating the forward link signal and modulating the backward link signal. For the backscatter link, the zero-power terminal uses backscattering to transmit signals.
[0099] It can be seen that the semi-passive zero-power terminal does not require a built-in battery to drive either the forward or reverse link. Although it uses energy stored in a capacitor during operation, the energy comes from the energy of radio waves collected by the energy harvesting module. Therefore, it is also a true zero-power terminal.
[0100] Semi-passive zero-power terminals inherit many advantages of passive zero-power terminals, and therefore have many advantages such as small size, light weight, low price and long service life.
[0101] (3) Active zero-power terminal
[0102] In some scenarios, zero-power terminals can also be active zero-power terminals, which can have a built-in battery. The battery powers the low-power computing module (i.e., low-power chip circuit) of the zero-power terminal, enabling demodulation of forward link signals and modulation of backward link signals. However, for backscatter links, zero-power terminals use backscattering for signal transmission. Therefore, the zero power consumption of this type of terminal is mainly reflected in the fact that the signal transmission of the reverse link does not require the terminal's own power, but instead uses backscattering.
[0103] Active zero-power terminals use a built-in battery to power the radio frequency chip, thereby increasing communication distance and improving communication reliability. Therefore, they are used in scenarios with relatively high requirements for communication distance and latency.
[0104] Cellular Passive Internet of Things
[0105] As industry applications increase, the types and application scenarios of connected devices are also expanding, placing higher demands on the price and power consumption of communication terminals. The application of battery-free, low-cost passive IoT devices has become a key technology for cellular IoT, enriching the types and quantities of network-connected terminals and truly realizing the Internet of Everything. Passive IoT devices can be based on zero-power communication technologies, such as Radio Frequency Identification (RFID), and can be extended to suit cellular IoT.
[0106] Zero-power terminals need to collect energy from the radio waves transmitted by network devices in order to power themselves. Therefore, before acquiring energy, the zero-power terminal is in a "power-off" state, meaning it cannot receive or send signals to the network device.
[0107] Because zero-power terminals have limited power supply, small data transmission volume, and limited processing capabilities, the communication system must be simple and applicable.
[0108] Figure 11 This is the architecture of the zero-power communication system provided in the embodiments of this application. Figure 1 ,like Figure 11 As shown, the system includes at least one of the following: a zero-power terminal, an access network node, a core network node, a data center node, and a service control node; wherein,

[0142] In this embodiment, the interface between the zero-power terminal and the access network node is the first interface. In some alternative embodiments, the first interface may be referred to as the Uu interface.
[0143] In this embodiment, the interface between the access network node and the core network node is a second interface. In some alternative embodiments, the second interface may be referred to as an NG interface.
[0144] It should be noted that the number of the above-mentioned functional nodes in a zero-power communication system can be one or more. For example, the number of zero-power terminals in a zero-power communication system can be one or more, and this application does not limit this.
[0145] Figure 12 This is the architecture of the zero-power communication system provided in the embodiments of this application. Figure 2 ,like Figure 12 As shown, the system includes at least one of the following: a zero-power terminal, a conventional terminal (e.g., a mobile phone), or an access network node. Figure 12 As shown, in scenario 1, the access network node can send a power supply signal and a trigger signal to the zero-power terminal. The zero-power terminal charges itself using the power supply signal and communicates with the access network node based on the trigger signal, sending a reverse reflection signal to the access network node. Scenario 1 is suitable for cellular direct connection communication scenarios. In scenario 2, the zero-power terminal can be considered an additional module of a conventional terminal. The conventional terminal can send a power supply signal and a trigger signal to the zero-power terminal. The zero-power terminal charges itself using the power supply signal and communicates with the conventional terminal based on the trigger signal, sending a wake-up signal to the conventional terminal. After being woken up, the conventional terminal can receive Uu signaling sent by the access network node and can also send data to the access network node. Scenario 2 is suitable for zero-power wake-up communication scenarios. In scenario 3, micro access network nodes (such as micro base stations) send only power supply signals to the zero-power terminal, while macro access network nodes (such as macro base stations) send only trigger signals to the zero-power terminal. The zero-power terminal is powered by the power supply signals and communicates with the macro access network nodes based on the trigger signals. It also sends a reverse reflection signal to the macro access network nodes. Scenario 3 is applicable to cellular direct connection communication scenarios for auxiliary functions.
[0146] from Figure 12It is understood that the access network node that powers the zero-power terminal and the access network node that communicates with the zero-power terminal can be the same or different. For example, in case 1, the access network node that powers the zero-power terminal and the access network node that communicates with the zero-power terminal are the same; in case 3, the access network node that powers the zero-power terminal and the access network node that communicates with the zero-power terminal are different. To improve the coverage and efficiency of power supply, dedicated access network nodes for power supply can be deployed (as in case 3). Alternatively, conventional terminals can be used to power and communicate with the zero-power terminal (as in case 2).
[0147] Based on the above description, zero-power terminals need to collect radio waves to obtain energy before they can operate. Therefore, before obtaining energy, zero-power terminals are in a "power-off" state, i.e., offline. Furthermore, for zero-power communication systems, network deployment may be in an islanded coverage manner, not a full coverage approach, so zero-power terminals will be offline due to lack of network coverage. Due to limited power supply and network coverage, zero-power terminals may frequently be offline. When a zero-power terminal is powered and enters the coverage area of a zero-power network, it will communicate with the network side; how to obtain wireless resources for communication is a problem that needs to be solved.
[0148] Therefore, the following technical solutions are proposed according to embodiments of this application. The technical solutions of the embodiments of this application may be applied to, but are not limited to, [various applications]. Figure 11 or Figure 12 The zero-power communication system shown is illustrated.
[0149] It should be noted that, unless otherwise specified, the "terminal" described in the embodiments of this application refers to a zero-power terminal.
[0150] It should be noted that the "network node" described in the embodiments of this application can be an access point (AP) or a radio access network (RAN) node. This application does not limit the type of network node; any node that can achieve network access can be used as the network node in this application.
[0151] To facilitate understanding of the technical solutions of the embodiments of this application, the technical solutions of this application are described in detail below through specific embodiments. The above-mentioned related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.
[0152] Figure 13 This is a flowchart illustrating the resource configuration method provided in an embodiment of this application, as shown below. Figure 13As shown, the resource allocation method includes the following steps:
[0153] Step 1301: The zero-power terminal receives first configuration information sent by the network node. The first configuration information is used to configure first radio resources and / or second radio resources, wherein the first radio resources are uplink resources and the second radio resources are downlink resources.
[0154] Step 1302: The zero-power terminal uses the first radio resource to send uplink data, and / or uses the second radio resource to receive an acknowledgment message for the uplink data.
[0155] In this embodiment of the application, when the zero-power terminal enters the network coverage area of the network node and is powered (which can be understood as the zero-power terminal being in a "power-on" state), it can communicate with the network node.
[0156] In this embodiment, a network node sends first configuration information to a zero-power terminal, and the zero-power terminal receives the first configuration information sent by the network node. Here, the network node configures a first radio resource and / or a second radio resource using the first configuration information, wherein the first radio resource is an uplink resource and the second radio resource is a downlink resource. The first radio resource is used by the zero-power terminal to send uplink data, and the second radio resource is used by the zero-power terminal to receive acknowledgment messages for the uplink data. After obtaining the first configuration information, the zero-power terminal uses the first radio resource to send uplink data and / or uses the second radio resource to receive acknowledgment messages for the uplink data. Correspondingly, the network node receives the uplink data sent by the zero-power terminal using the first radio resource and / or sends acknowledgment messages for the uplink data to the zero-power terminal using the second radio resource.
[0157] The following explains the specific implementation of the first configuration information.
[0158] It should be noted that the description of "uplink signal" in the embodiments of this application can also be replaced with "uplink sequence" or "uplink signal sequence".
[0159] Option 1
[0160] In this embodiment, the zero-power terminal sends a first uplink signal to the network node on a third radio resource, and correspondingly, the network node receives the first uplink signal sent by the zero-power terminal on the third radio resource, wherein the third radio resource is an uplink resource. The network node sends a first response message to the zero-power terminal on a fourth radio resource, and correspondingly, the zero-power terminal receives the first response message sent by the network node on the fourth radio resource, wherein the first response message carries the first configuration information, and the fourth radio resource is a downlink resource.
[0161] In some alternative implementations, before the zero-power terminal sends a first uplink signal to the network node on a third radio resource, the method further includes:
[0162] The network node sends network system information to the zero-power terminal, and correspondingly, the zero-power terminal receives the network system information sent by the network node. The network system information includes second configuration information, which is used for at least one of the following:
[0163] Configure or generate at least one uplink signal;
[0164] Configure at least one third wireless resource;
[0165] Configure at least one fourth wireless resource;
[0166] The third radio resource is used to transmit uplink signals, and the fourth resource is used to receive response messages.
[0167] In the above scheme, each of the at least one uplink signal is associated with a signal identifier.
[0168] In the above scheme, each of the at least one third radio resources is associated with a resource identifier.
[0169] In the above scheme, each of the at least one fourth radio resource is associated with a resource identifier.
[0170] In some optional embodiments, a first correspondence exists between the at least one third radio resource and the at least one fourth radio resource, wherein the first correspondence includes at least one of the following: a relationship where one third radio resource corresponds to one fourth radio resource, or a relationship where multiple third radio resources correspond to one fourth radio resource. Optionally, the first correspondence may be given in the network system information.
[0171] Here, the relationship of "one third radio resource corresponding to one fourth radio resource" can also be understood as a "one-to-one relationship". The relationship of "multiple third radio resources corresponding to one fourth radio resource" can also be understood as a "many-to-one relationship".
[0172] As an example: Figure 14 A one-to-one mapping relationship between third and fourth radio resources is given, where one third radio resource corresponds to one fourth radio resource. Figure 15 A many-to-one mapping relationship between third and fourth radio resources is given, where 3 third radio resources correspond to 1 fourth radio resource.
[0173] It should be noted that the correspondence between the third and fourth radio resources must satisfy the following conditions: a third radio resource has only one corresponding fourth radio resource, and a fourth radio resource may have one or more corresponding third radio resources.
[0174] In the above scheme, one third radio resource and one fourth radio resource with a one-to-one correspondence can be called a radio resource pair. In other words, there is a one-to-one correspondence between the third radio resource and the fourth radio resource in a radio resource pair.
[0175] In this embodiment, after obtaining the second configuration information, the zero-power terminal selects the first uplink signal and / or selects a third radio resource for transmitting the first uplink signal based on the second configuration information, and then transmits the selected first uplink signal on the selected third radio resource. Subsequently, the zero-power terminal receives a first response message sent by a network node. The first response message carries the first configuration information. Further, optionally, the first response message also carries at least one of the following: a first signal identifier, a first resource identifier, and a first time advance (TA) amount; wherein the first signal identifier is the signal identifier of the first uplink signal; the first resource identifier is the resource identifier of the third radio resource used to transmit the first uplink signal; and the first TA amount is the TA amount by which the zero-power terminal transmits the uplink data.
[0176] Here, the first signal identifier and / or the first resource identifier are used by the zero-power terminal to determine whether the first wireless resource and / or the second wireless resource configured in the first configuration information is a wireless resource allocated to itself.
[0177] For example, a zero-power terminal uses resource 1 to send uplink signal 1. After receiving uplink signal 1 on resource 1, a network node sends a first response message to the zero-power terminal. The first response message carries the resource identifier of resource 1 and / or the signal identifier of uplink signal 1, and optionally, also carries a first TA quantity. After receiving the first response message, the zero-power terminal compares the resource identifier and / or signal identifier carried in the first response message with the resource identifier and / or signal identifier of the resource 1 it is using and / or the signal identifier of uplink signal 1. If they match, it determines that the first radio resource and / or the second radio resource configured in the first configuration information in the first response message are radio resources allocated to it.
[0178] In some alternative implementations, the first configuration information is used to configure a first radio resource and / or a second radio resource. Based on this, the zero-power terminal uses the first radio resource configured in the first configuration information to transmit uplink data; and / or, the zero-power terminal uses the second radio resource configured in the first configuration information to receive an acknowledgment message for the uplink data.
[0179] Optionally, in the above scheme, the uplink data and / or the confirmation message carry the terminal identifier of the zero-power terminal.
[0180] In some optional implementations, the zero-power terminal determines whether its own terminal identifier is carried in the confirmation message; if the confirmation message carries its own terminal identifier, the zero-power terminal determines that the uplink data transmission was successful; if the confirmation message does not carry its own terminal identifier, the zero-power terminal determines that the uplink data transmission failed. Further, optionally, if the zero-power terminal determines that the uplink data transmission failed, the zero-power terminal retransmits the uplink data. Here, when the zero-power terminal retransmits the uplink data, it may change the first radio resource used and / or increase the transmission power of the first radio resource.
[0181] Option 2
[0182] In this embodiment, the zero-power terminal sends a first uplink signal to the network node on a third radio resource, and correspondingly, the network node receives the first uplink signal sent by the zero-power terminal on the third radio resource, wherein the third radio resource is an uplink resource. The network node sends a broadcast message, and correspondingly, the zero-power terminal receives the broadcast message sent by the network node, the broadcast message carrying the first configuration information.
[0183] In some alternative implementations, before the zero-power terminal sends a first uplink signal to the network node on a third radio resource, the method further includes:
[0184] The network node sends network system information to the zero-power terminal, and correspondingly, the zero-power terminal receives the network system information sent by the network node. The network system information includes second configuration information, which is used for at least one of the following:
[0185] Configure or generate at least one uplink signal;
[0186] Configure at least one third wireless resource;
[0187] Configure at least one fourth wireless resource;
[0188] The third radio resource is used to transmit uplink signals, and the fourth resource is used to receive response messages.
[0189] In the above scheme, each of the at least one uplink signal is associated with a signal identifier.
[0190] In the above scheme, each of the at least one third radio resources is associated with a resource identifier.
[0191] In the above scheme, each of the at least one fourth radio resource is associated with a resource identifier.
[0192] In some optional embodiments, a first correspondence exists between the at least one third radio resource and the at least one fourth radio resource, wherein the first correspondence includes at least one of the following: a relationship where one third radio resource corresponds to one fourth radio resource, or a relationship where multiple third radio resources correspond to one fourth radio resource. Optionally, the first correspondence may be given in the network system information.
[0193] Here, the relationship of "one third radio resource corresponding to one fourth radio resource" can also be understood as a "one-to-one relationship". The relationship of "multiple third radio resources corresponding to one fourth radio resource" can also be understood as a "many-to-one relationship".
[0194] As an example: Figure 14 A one-to-one mapping relationship between third and fourth radio resources is given, where one third radio resource corresponds to one fourth radio resource. Figure 15 A many-to-one mapping relationship between third and fourth radio resources is given, where 3 third radio resources correspond to 1 fourth radio resource.
[0195] It should be noted that the correspondence between the third and fourth radio resources must satisfy the following conditions: a third radio resource has only one corresponding fourth radio resource, and a fourth radio resource may have one or more corresponding third radio resources.
[0196] In the above scheme, one third radio resource and one fourth radio resource with a one-to-one correspondence can be called a radio resource pair. In other words, there is a one-to-one correspondence between the third radio resource and the fourth radio resource in a radio resource pair.
[0197] In this embodiment, after obtaining the second configuration information, the zero-power terminal selects the first uplink signal and / or selects a third radio resource for transmitting the first uplink signal based on the second configuration information, and then transmits the selected first uplink signal on the selected third radio resource. Subsequently, the zero-power terminal receives a broadcast message sent by a network node. The broadcast message carries the first configuration information.
[0198] In some alternative implementations, the first configuration information is used to configure at least one first radio resource group and / or at least one second radio resource group.
[0199] In some alternative implementations, the at least one first radio resource group and the at least one second radio resource group have a corresponding relationship; or, each first radio resource in the at least one first radio resource group and each second radio resource in the at least one second radio resource group have a corresponding relationship.
[0200] In the above scheme, one first radio resource and one second radio resource with a one-to-one correspondence can be called a radio resource pair. In other words, there is a one-to-one correspondence between the first radio resource and the second radio resource in a radio resource pair.
[0201] In some alternative implementations, each of the at least one first radio resource group is associated with a signal identifier and / or a resource identifier. Based on this, the zero-power terminal determines the associated first radio resource group from the at least one first radio resource group based on the signal identifier of its own transmitted first uplink signal and / or the resource identifier of a third radio resource used to transmit the first uplink signal; the zero-power terminal then selects a first radio resource from the associated first radio resource group to transmit uplink data.
[0202] In some alternative implementations, the zero-power terminal selects a first radio resource in the associated first radio resource group to send uplink data based on its own terminal identifier.
[0203] As an example: the zero-power terminal determines the number of the selected first wireless resource based on the following formula:
[0204] UE ID mod N=k;
[0205] Wherein, UE ID is the terminal identifier of the zero-power terminal, N is the number of first radio resources in the associated first radio resource group, k is the number of the selected first radio resource in the associated first radio resource group, and mod is the modulo operation.
[0206] In some alternative implementations, the zero-power terminal uses a second radio resource corresponding to the first radio resource used to send uplink data to receive the acknowledgment message for the uplink data.
[0207] Optionally, in the above scheme, the uplink data and / or the confirmation message carry the terminal identifier of the zero-power terminal.
[0208] In some optional implementations, the zero-power terminal determines whether its own terminal identifier is carried in the confirmation message; if the confirmation message carries its own terminal identifier, the zero-power terminal determines that the uplink data transmission was successful; if the confirmation message does not carry its own terminal identifier, the zero-power terminal determines that the uplink data transmission failed. Further, optionally, if the zero-power terminal determines that the uplink data transmission failed, the zero-power terminal retransmits the uplink data. Here, when the zero-power terminal retransmits the uplink data, it may change the first radio resource used and / or increase the transmission power of the first radio resource.
[0209] Option 3
[0210] In this embodiment of the application, the network node sends network system information to the zero-power terminal, and correspondingly, the zero-power terminal receives the network system information sent by the network node, wherein the network system information carries the first configuration information.
[0211] In some alternative implementations, the first configuration information is used to configure at least one first radio resource and / or at least one second radio resource.
[0212] In some alternative implementations, the at least one first wireless resource and the at least one second wireless resource have a corresponding relationship.
[0213] In the above scheme, one first radio resource and one second radio resource with a one-to-one correspondence can be called a radio resource pair. In other words, there is a one-to-one correspondence between the first radio resource and the second radio resource in a radio resource pair.
[0214] In this embodiment of the application, after the zero-power terminal obtains the first configuration information, it selects a first wireless resource from the at least one first wireless resource to send uplink data based on the first configuration information.
[0215] In some alternative implementations, the zero-power terminal selects a first radio resource from the at least one first radio resource to transmit uplink data based on its own terminal identifier.
[0216] As an example: the zero-power terminal determines the number of the selected first wireless resource based on the following formula:
[0217] UE ID mod M=j;
[0218] Wherein, UE ID is the terminal identifier of the zero-power terminal, M is the number of the first radio resources in the at least one first radio resource, j is the number of the selected first radio resource in the at least one first radio resource, and mod is the modulo operation.
[0219] In some alternative implementations, the zero-power terminal uses a second radio resource corresponding to the first radio resource used to send uplink data to receive the acknowledgment message for the uplink data.
[0220] Optionally, in the above scheme, the uplink data and / or the confirmation message carry the terminal identifier of the zero-power terminal.
[0221] In some optional implementations, the zero-power terminal determines whether its own terminal identifier is carried in the confirmation message; if the confirmation message carries its own terminal identifier, the zero-power terminal determines that the uplink data transmission was successful; if the confirmation message does not carry its own terminal identifier, the zero-power terminal determines that the uplink data transmission failed. Further, optionally, if the zero-power terminal determines that the uplink data transmission failed, the zero-power terminal retransmits the uplink data. Here, when the zero-power terminal retransmits the uplink data, it may change the first radio resource used and / or increase the transmission power of the first radio resource.
[0222] It should be noted that in the technical solutions of this application embodiment, "uplink data confirmation message" can also be replaced with "downlink data", and the solution of replacing with "downlink data" is also applicable to this application.
[0223] The technical solutions of the embodiments of this application are illustrated below with specific application examples.
[0224] Application Example 1
[0225] When a zero-power terminal enters the coverage area of a zero-power network and receives power, it receives network system information sent by network nodes.
[0226] The network system information includes second configuration information, which is used for at least one of the following: configuring or generating at least one uplink signal; configuring at least one uplink radio resource (i.e., a third radio resource); and configuring at least one downlink radio resource (i.e., a fourth radio resource).
[0227] Here, each of the at least one uplink signal is associated with a signal identifier. A signal identifier is used to uniquely identify an uplink signal.
[0228] Here, each of the at least one uplink radio resource is associated with a resource identifier. The uplink radio resource is used to transmit uplink signals.
[0229] Here, each of the at least one downlink radio resource is associated with a resource identifier. The downlink resource is used to receive response messages.
[0230] In the above scheme, there can be a one-to-one correspondence between the downlink resources used to receive response messages and the uplink resources used to send uplink signals (e.g., Figure 14 As shown), or a many-to-one correspondence (such as...). Figure 15 (As shown). Optionally, this mapping relationship will be configured in the network system information.
[0231] When the zero-power terminal actively sends data to the network side or the network side triggers the zero-power terminal to report data, the zero-power terminal, based on the second configuration information, selects a first uplink signal and / or uplink resources for sending the first uplink signal, and then sends the first uplink signal on the selected radio resources. The zero-power terminal receives a first response message sent by the network node.
[0232] The first response message includes first configuration information, which is used to configure an uplink resource (i.e., a first radio resource) and / or a downlink resource (i.e., a second radio resource). The uplink resource is used to transmit uplink data, and the downlink resource is used to receive acknowledgment messages for uplink data. Optionally, the first response message further includes a signal identifier for a first uplink signal and / or a resource identifier for the uplink resource used to transmit the first uplink signal. This signal identifier and / or resource identifier is used by the zero-power terminal to identify whether the uplink resource and / or downlink resource configured in the first configuration information are resources allocated to it. Specifically, the zero-power terminal compares the signal identifier of its own first uplink signal and / or the resource identifier of the radio resource used to transmit the first uplink signal with the signal identifier and / or resource identifier carried in the first response message. If they match, the zero-power terminal considers the uplink resource and / or downlink resource configured in the first configuration information to be resources allocated to it; if they do not match, the zero-power terminal considers the uplink resource and / or downlink resource configured in the first configuration information to be resources not allocated to it. Further, optionally, the first response message also includes an uplink transmission TA amount (i.e., a first TA amount), used to indicate the amount of TA that the zero-power terminal transmits uplink data.
[0233] As an example, Figure 16 and Figure 17 The content of the first response message is given, in which, Figure 16 The first response message includes a signal identifier, a resource identifier, an uplink grant (UL grant), and a downlink grant (DL grant). The uplink grant is used to determine uplink resources, and the downlink grant is used to determine downlink resources. Figure 17 The first response message includes a signal identifier, a resource identifier, a TA (Transmission Action), an uplink grant (UL grant), and a downlink grant (DL grant). The uplink grant is used to determine uplink resources, and the downlink grant is used to determine downlink resources. It should be noted that... Figure 16 and Figure 17 This is for illustrative purposes only, and the position and length of each field can be adjusted accordingly.
[0234] In one scenario, if the zero-power terminal does not receive the first response message or the response message received by the zero-power terminal is not its own response message, then the zero-power terminal can continue to select uplink resources and uplink signals to send.
[0235] In this embodiment, after receiving a first response message, the zero-power terminal sends uplink data on the uplink resources configured in the first response message, wherein the uplink data includes the terminal identifier of the zero-power terminal. After receiving the uplink data, the network node sends an acknowledgment message for the uplink data on the downlink resources configured in the first response message, wherein the acknowledgment message includes the terminal identifier of the zero-power terminal. After receiving the acknowledgment message on the downlink resources configured in the first response message, the zero-power terminal determines whether the uplink data transmission was successful based on whether the terminal identifier included in the acknowledgment message is its own terminal identifier. Specifically, if the terminal identifier included in the acknowledgment message is its own terminal identifier, the uplink data transmission is determined to be successful; if the terminal identifier included in the acknowledgment message is not its own terminal identifier, the uplink data transmission is determined to have failed. Further, if the uplink data transmission is successful, the zero-power terminal's data transmission process ends; if the uplink data transmission fails, the zero-power terminal retransmits the uplink data.
[0236] Application Example 2
[0237] When a zero-power terminal enters the coverage area of a zero-power network and receives power, it receives network system information sent by network nodes.
[0238] The network system information includes second configuration information, which is used for at least one of the following: configuring or generating at least one uplink signal; configuring at least one uplink radio resource (i.e., a third radio resource); and configuring at least one downlink radio resource (i.e., a fourth radio resource).
[0239] Here, each of the at least one uplink signal is associated with a signal identifier. A signal identifier is used to uniquely identify an uplink signal.
[0240] Here, each of the at least one uplink radio resource is associated with a resource identifier. The uplink radio resource is used to transmit uplink signals.
[0241] Here, each of the at least one downlink radio resource is associated with a resource identifier. The downlink resource is used to receive response messages.
[0242] In the above scheme, there can be a one-to-one correspondence between the downlink resources used to receive response messages and the uplink resources used to send uplink signals (e.g., Figure 14 As shown), or a many-to-one correspondence (such as...). Figure 15 (As shown). Optionally, this mapping relationship will be configured in the network system information.
[0243] When a zero-power terminal actively sends data to the network side or is triggered by the network side to report data, the zero-power terminal selects a first uplink signal and / or uplink resources for sending the first uplink signal based on the second configuration information, and then sends the first uplink signal on the selected radio resources. After receiving the first uplink signal sent by the zero-power terminal, the network node sends the first configuration information. Optionally, the network node can send the first configuration information via broadcast message.
[0244] The first configuration information is used to configure at least one uplink resource (i.e., a first radio resource) group and / or at least one downlink resource (i.e., a second radio resource) group, or the first configuration information is used to configure at least one radio resource pair, each radio resource pair including one corresponding uplink resource and one downlink resource. The uplink resource is used to transmit uplink data, and the downlink resource is used to receive acknowledgment messages for uplink data. Here, each uplink resource group is associated with a signal identifier and / or a resource identifier.
[0245] In this embodiment, after obtaining the first configuration information, the zero-power terminal determines the associated uplink resource group based on the signal identifier of its own first uplink signal and / or the resource identifier of the uplink resource used to send the first uplink signal. Then, the zero-power terminal selects an uplink resource from the uplink resource group to send uplink data based on its own terminal identifier. For example, the zero-power terminal determines the number of the selected uplink resource based on the following formula: UE ID mod N = k; where UE ID is the terminal identifier of the zero-power terminal, N is the number of uplink resources in the associated uplink resource group, k is the number of the selected uplink resource in the associated uplink resource group, and mod is the modulo operation. The uplink data includes the terminal identifier of the zero-power terminal. After receiving the uplink data, the network node sends an acknowledgment message for the uplink data on the downlink resource (optionally, it can be the downlink resource corresponding to the uplink resource used to send the uplink data). The acknowledgment message includes the terminal identifier of the zero-power terminal. After receiving the acknowledgment message on the downlink resource, the zero-power terminal determines whether the uplink data was successfully sent based on whether the terminal identifier included in the acknowledgment message is its own terminal identifier. Specifically, if the terminal identifier contained in the confirmation message is its own terminal identifier, then the uplink data transmission is determined to be successful; if the terminal identifier contained in the confirmation message is not its own terminal identifier, then the uplink data transmission is determined to have failed. Furthermore, if the uplink data transmission is successful, the zero-power terminal's data transmission process ends; if the uplink data transmission fails, the zero-power terminal retransmits the uplink data.
[0246] Application Example 3
[0247] When a zero-power terminal enters the coverage area of a zero-power network and receives power, it receives network system information sent by network nodes.
[0248] The network system information includes first configuration information, which is used to configure at least one uplink resource (i.e., a first radio resource) and / or at least one downlink resource (i.e., a second radio resource), or the first configuration information is used to configure at least one radio resource pair, each radio resource pair including one corresponding uplink resource and one corresponding downlink resource. The uplink resource is used to transmit uplink data, and the downlink resource is used to receive acknowledgment messages for uplink data.
[0249] In this embodiment, after obtaining the first configuration information, the zero-power terminal selects an uplink resource to transmit uplink data. Optionally, the zero-power terminal selects an uplink resource from at least one uplink resource based on its own terminal identifier. For example, the zero-power terminal determines the selected uplink resource number based on the following formula: UE ID mod M = j; where UE ID is the terminal identifier of the zero-power terminal, M is the number of uplink resources included in the at least one uplink resource, j is the number of the selected uplink resource in the at least one uplink resource, and mod is the modulo operation. The uplink data includes the terminal identifier of the zero-power terminal. After receiving the uplink data, the network node sends an acknowledgment message for the uplink data on a downlink resource (optionally, it can be the downlink resource corresponding to the uplink resource used to transmit the uplink data). The acknowledgment message includes the terminal identifier of the zero-power terminal. After receiving the acknowledgment message on the downlink resource, the zero-power terminal determines whether the uplink data transmission was successful based on whether the terminal identifier included in the acknowledgment message is its own terminal identifier. Specifically, if the terminal identifier contained in the confirmation message is its own terminal identifier, then the uplink data transmission is determined to be successful; if the terminal identifier contained in the confirmation message is not its own terminal identifier, then the uplink data transmission is determined to have failed. Furthermore, if the uplink data transmission is successful, the zero-power terminal's data transmission process ends; if the uplink data transmission fails, the zero-power terminal retransmits the uplink data.
[0250] The technical solution of this application embodiment clarifies the method for a zero-power terminal to apply for and select wireless resources for data transmission, enabling the zero-power terminal to access the network for data transmission.
