[0133] FIG. 1a is an architecture schematic diagram of a communication system according to embodiments of the present disclosure.

[0134] As shown in FIG. 1a, the communication system 100 includes a terminal 101 and a node device 102.

[0135] In some embodiments, the terminal 101 can be an Ambient-IoT terminal or referred to as a device. The terminal 101 can not be configured with a battery, and is excited and powered by received electromagnetic signals; or is configured with a battery having a small amount of electrical storage function, and obtains energy of the battery by means of obtaining electromagnetic waves, thermal energy, kinetic energy, and / or the like from the outside world.

[0136] Optionally, the power acquisition and storage capability of the terminal 101 varies according to the type and working mode of the terminal 101. For example, the types of the terminal 101 can include the following:

[0137] Device 1: has the capability of energy storage, but cannot independently generate or amplify signals. For example, the device 1 uses the working mode of backscattering or backscattering communication, and does not have the capability of amplifying downlink (DL) signals and / or uplink (UL) signals.

[0138] Device 2a: has the capability of energy storage, but cannot independently generate signals. For example, the device 2a uses the working mode of backscattering, and can use the stored energy for DL and / or UL signal amplification.

[0139] Device 2b: has the capability of energy storage, and can independently generate signals, for example, has a radio frequency (RF) module that actively transmits signals.

[0140] Among the above types of the terminal 101, the capability of the device 2b is the strongest, and the cost of the terminal is the highest. The capabilities of the devices 1 and 2a are weak, and the cost of the terminal is low. In addition, the devices 1 and 2a need to use the working mode of backscattering, and cannot actively transmit signals, and need other nodes to provide continuous waves (CW) as energy input. The device 2b can actively generate signals in the circuit of the device by using the stored energy, and thus does not need CW. In addition, the power consumption of the working mode of the device 1 or the device 2a is lower than that of the working mode of the device 2b.

[0141] In some embodiments, the terminal 101 includes at least one of a mobile phone, a wearable device, an Internet of Things device, a communication-capable automobile, a smart automobile, a tablet (Pad), a wireless transceiver-equipped computer, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, and the like, but is not limited thereto.

[0142] In some embodiments, in an Ambient-IoT scenario, referring to FIG. 1b, the communication system 100 can further include at least one of a continuous wave node (CWN) 103, an energy source node (ESN) 104, a downlink signal node (DSN) 105, and an uplink receiver (UR) 106.

[0143] The CWN 103 is configured to transmit a CW, and the terminal 101 can transmit uplink information based on backscattering using the CW. The CWN 103 can implement an excitation function for device 1 and device 2a to perform uplink transmission based on backscattering. In addition, the CW can serve as an energy source (ES) to provide energy for the terminal 101, and the terminal 101 can receive the CW and store energy.

[0144] The ESN 104 is configured to provide energy for the terminal 101. For example, the ESN 104 provides functions for device 2a and device 2b, and since device 2a has limited energy storage capability, no ES signal other than the CW can be defined for device 2a. Alternatively, the ES can also be used for device 2a.

[0145] The DSN 105 is configured to transmit downlink information or indication information. The DSN 105 can transmit signaling to the terminal 101 to trigger uplink transmission of the terminal 101.

[0146] The UR 106 is configured to receive uplink information transmitted by the Ambient-IoT terminal 101. For example, the UR 106 receives uplink information transmitted by the terminal 101 based on backscatter communication, or the UR 106 receives uplink information actively transmitted by the terminal 101.

[0147] In some embodiments, the functions of the different nodes described above can be implemented or supported by a device, for example, a device supports the functions of multiple nodes described above or supports the functions of all nodes described above. Alternatively, a device corresponds to only one of the nodes described above. The network can coordinate the behavior of the different nodes, such as the CWN 103, the ESN 104, and the UR 106, to support efficient communication with the terminal 101.

[0148] In some embodiments, based on the nodes described above, four links can be included in the Ambient-IoT communication system, for example, including: a link 1 for transmitting downlink information, a link 2 for receiving uplink information, a link 3 for transmitting a CW, and a link 4 for transmitting an energy signal.

[0149] The link 4 can be controlled by the network, for example, the network can control the ESN 104 to turn on or turn off energy supply to the terminal 101. The energy supplied by the ESN 104 can come from electromagnetic waves or non-electromagnetic waves; at this time, the ESN 104 can better cooperate with network scheduling and other functions, so as to ensure that the terminal 101 is energized while minimizing the impact on the communication of the terminal 101. Alternatively, the ESN 104 is not controlled by the network, or in other words, the terminal 101 flexibly collects energy according to the terminal 101 capability and the energy source in the actual environment, for example, collects electromagnetic wave or non-electromagnetic wave energy without a specific ESN 104 node; at this time, it can be considered that the link 4 does not exist.

[0150] The four links in the embodiments described above involve several nodes such as the DSN 105, the CWN 103, the ESN 104, and the UR 106, which can be independently set respectively, or can be the same node or device, or 2, 3, or 4 of them can be set as one node or device. For example, in some embodiments, the link 4 can be omitted or not exist.

[0151] In some embodiments, the node device 102 is a network device or the DSN 105; alternatively, the node device 102 can include the DSN 105 and the UR 106. The DSN 105 can be a network device or a relay device; alternatively, the node device 102 includes at least one of the CWN 103, the ESN 104, the DSN 105, and the UR 106.

[0152] Optionally, the network device can include at least one of an access network device and a core network device.

[0153] Optionally, the access network device is at least one of a node or device that accesses a terminal to a wireless network, and the access network device can include at least one of an evolved node B (eNB) in a 5G communication system, a next generation eNB (ng-eNB), a next generation node B (gNB), a node B (NB), a home node B (HNB), a home evolved node B (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, an access node in a wireless fidelity (WiFi) system, but is not limited thereto.

[0157] In some embodiments, the technical solutions of the present disclosure can be applied to the Open RAN architecture, at this time, the interfaces between the access network devices or within the access network devices involved in the embodiments of the present disclosure can become internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be realized through software or programs.

[0158] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. It can be known by those skilled in the art that, with the evolution of system architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0159] The following embodiments of the present disclosure can be applied to the communication system 100 shown in FIG. 1a or FIG. 1b, or part of the subject, but are not limited thereto.

[0160] The subjects shown in FIG. 1a or FIG. 1b are illustrative. The communication system can include all or part of the subjects in FIG. 1a or FIG. 1b, or other subjects other than FIG. 1a or FIG. 1b. The number and form of each subject is arbitrary. The connection relationship between each subject is illustrative. Each subject can be connected or not connected.

Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0162] In some possible implementation, in a warehouse inventory process of Ambient IoT or Radio Frequency Identification (RFID), the terminal 101 can include an RFID tag. After receiving a Query signaling, the RFID tag can set a random value counter according to a Q value in the Query signaling, counter <= Q. If the counter = 0, the RFID tag can start to perform backscattering to send uplink information, for example, RN16 (a 16-bit random number) used to temporarily represent a tag ID. If the counter value is not 0, the RFID tag does not send information, and waits to receive or repeat a QueryRep command. The RFID tag decreases the counter value by 1 each time it receives a QueryRep command, until the counter value is reduced to 0, at which time the RFID tag will switch to a reply state and backscatter uplink information. If a confirmation information ACK is further received, it is confirmed that the RFID tag is successfully accessed; otherwise, if an invalid ACK is received, or an ACK with erroneous RN16 is received, or no corresponding command is received within a set time period, the RFID tag considers that the access is unsuccessful.

[0163] In the above process, the network or the node device 102 triggers the decrement process of the random number each time by sending downlink signaling such as the Query signaling or the QueryRep signaling. However, the terminal 101 can miss the downlink signaling, for example, the terminal 101 misses the QueryRep signaling, and thus the random value is not decremented. After the network side sends the QueryRep signaling Q times, it is considered that the random values of all the terminals 101 have been decremented to 0, and it is considered that all the terminals 101 obtain the uplink sending opportunity. However, the terminal 101 that misses the QueryRep signaling has a random value greater than 0, and thus does not obtain the uplink sending opportunity. In addition, in the above process, the network needs to send the downlink signaling such as the Query signaling or the QueryRep signaling multiple times, and thus the resource consumption is large.

[0164] Embodiments of the present disclosure provide a method for sending and receiving uplink information, which avoids the above problems of missing and large resource consumption.

[0165] FIG. 2 is an interaction diagram of a method for sending and receiving uplink information according to an embodiment of the present disclosure. As shown in FIG. 2, the present disclosure relates to a method for sending and receiving uplink information, and the above method includes:

[0166] In step S2101, the node device 102 sends first indication information to the terminal 101.

[0167] In some embodiments, the node device 102 can be a network device such as a base station, or a relay device such as a relay UE. Alternatively, the node device 102 can be the DSN 105 shown in FIG. 1b, or include one or more nodes shown in FIG. 1b.

[0168] In some embodiments, the terminal 101 is an Ambient IoT terminal.

[0169] In some embodiments, the first indication information can also be referred to as first downlink signaling, which is signaling for starting the first terminal 101 reporting process in the inventory process. For example, the first indication information is Query signaling.

[0170] In some embodiments, the first indication information is used to indicate a parameter value of the time domain channel resource, which is the Q value.

[0171] Optionally, the first indication information indicates that there are at most Q time domain channel resources.

[0172] In some embodiments, the terminal 101 receives the first indication information to learn the available time domain channel resources, or to determine the uplink transmission opportunity.

[0173] In some embodiments, the node device 102 can send a synchronization signal in a periodic or semi-persistent manner to provide time information for the terminal 101, so as to facilitate the terminal 101 to achieve time synchronization.

[0174] Step S2102, the terminal 101 generates a random number (counter) according to the first indication information.

[0175] In some embodiments, the random number is generated according to the parameter value. For example, 0≤initial value of the random number generated by the terminal 101≤third value, and the third value is determined according to the parameter value.

[0176] Optionally, the third value is the parameter value Q.

[0177] Optionally, the third value is 2 Q -1.

[0178] In an example, if the generated random number or the initial value of the random number is 0, the terminal 101 can directly execute step S2104.

[0179] In another example, if the generated random number or the initial value of the random number is not 0, the terminal 101 can execute step S2103.

[0180] Step S2103, the terminal 101 reduces the random number by a first value every first time length from the generated random number.

[0181] In some embodiments, the first value is 1 in the inventory process.

[0182] In some embodiments, the first time length is configured by the node device 102 or defined by a protocol.

[0183] Optionally, the first time length is configured by the first indication information.

[0184] In some embodiments, the random number is decremented once every first time length, starting from the generation of the random number, such as the initial value of the random number. For example, after the first first time length, the random number becomes (initial value-1); after the second first time length, the random number becomes (initial value-2), and so on, until the random number is reduced to the second value.

[0185] In some embodiments, when the random number is reduced to the second value, the terminal 101 performs step S2104.

[0186] Step S2104, when the random number is reduced to the second value, the terminal 101 sends uplink information to the node device 102.

[0187] In some embodiments, the node device 102 includes the UR 106.

[0188] In some embodiments, the second value can be 0, for example, when the random number is reduced to 0, the terminal 101 sends the uplink information.

[0189] In some embodiments, the terminal 101 sends the uplink information on the time domain channel resource with a time length of the second time length.

[0190] Optionally, the time domain channel resource on which the terminal 101 sends the uplink information is a time domain channel resource with a starting time of the time when the random number is reduced to 0 and a duration of the second time length.

[0191] In some embodiments, the second time length is configured by the node device 102 or defined by a protocol.

[0192] Optionally, the second time length is sent by the first indication information.

[0193] In some embodiments, the node device 102 receives the uplink information.

[0194] In some embodiments, the uplink information sent by the terminal 101 does not require feedback response of the node device 102; or, requires feedback response of the node device 102, such as step S2105.

[0195] In some embodiments, the second time length includes the time length of the terminal 101 sending the uplink information.

[0196] In some embodiments, the second time length includes a maximum duration for the terminal 101 to send uplink information. Alternatively, the second time length includes a maximum duration and a maximum interval, where the maximum interval is a maximum interval between a feedback response and corresponding uplink information.

[0197] Optionally, the maximum duration can be configured by the network or defined by a protocol.

[0198] In an example, the maximum duration defined by a protocol or configured by the network is T2, and the second time length is denoted as T1. In this example, T1 = T2, if the uplink information does not require a feedback response.

[0199] In another example, the maximum duration defined by a protocol or configured by the network is T2, and the second time length is denoted as T1. In this example, T1 = T2 + T3, if the uplink information requires a feedback response, and the maximum interval for each node device 102 to provide the feedback response is T3.

[0200] In some embodiments, the first time length is greater than or equal to the second time length. For example, the first time length is denoted as T4, and the second time length is denoted as T1, where T4 >= T1. In an example, T4 = T1.

[0201] In some embodiments, the terminal 101 can communicate based on a backscattering method. Backscattering or backscatter communication is a modulation and transmission technology with extremely low power consumption based on the principle of backscattering of radio frequency signals, and is a means to realize the Internet of Everything. In backscatter communication, a radio frequency signal such as an electromagnetic wave is received by the terminal 101, and the internal circuit of the terminal 101 modulates the information to be transmitted by means of load impedance modulation or the like on the basis of the incident electromagnetic wave, and then sends out the modulated electromagnetic wave carrying information. There are various ways to modulate information, such as amplitude shift keying (ASK), frequency shift keying (FSK), or phase shift keying (PSK).

[0202] In some embodiments, for a terminal 101 using a backscattering method, the workflow can include that the network device sends a downlink instruction (such as a Query signaling or a QueryRep signaling) to the terminal 101, and the terminal 101 sends a corresponding response to the network device or performs a corresponding operation after receiving the downlink instruction.

[0203] In some embodiments, the terminal 101 needs a source of energy, such as the CWN 104, to provide a CW for reflection while sending uplink information or data (i.e., link 3 is needed). The CW is generally constant amplitude. The frequency of the electromagnetic wave reflected by the terminal 101 can be the same as the frequency of the CW or can have some offset, and the size of the offset is related to the hardware characteristics of the terminal 101. For example, the offset can be a fixed value, or, if the hardware of the terminal 101 supports it, the offset can also support multiple fixed values, or can be a dynamically adjustable value.

[0204] In some embodiments, for an Ambient-IoT terminal 101, one way of utilizing frequency resources is to divide the available spectrum into multiple sub-channels, each of which occupies a fixed bandwidth, and the sub-channels are orthogonal in the frequency domain. The terminal 101 can be instructed by the network to use one or more sub-channels to transmit data, or can select one or more sub-channels to transmit data through some algorithm. For a terminal 101 that uses backscattering, the operating bandwidth of its antenna is relatively wide, such as tens of megahertz (Mhz). If the CWN 103 transmits a CW at multiple frequency points within the operating bandwidth of the terminal 101, the terminal 101 will receive the CW at multiple frequency points and backscatter the multiple CWs, i.e., the terminal 101 does not have the ability to reflect only the CW of the selected specific sub-channel. The uplink sub-channel that the terminal 101 can use to send uplink actually depends on the frequency of the CW and the ability of the offset.

[0205] In step S2105, the node device 102 sends feedback response information to the terminal 101.

[0206] In some embodiments, the feedback response information indicates whether the node device 102 has received the uplink information.

[0207] In some embodiments, the node device 102 is a node, such as the UR 106, that needs to receive uplink information. The feedback response information corresponds to the uplink information.

[0208] In some embodiments, the feedback response information can include acknowledgement information (ACK) or negative information (NACK).

[0209] In some embodiments, the feedback response information can be sent on the time domain channel resource on which the above-mentioned uplink information is located.

[0210] In some embodiments, the terminal 101 receives the feedback response information on the time domain channel resource on which the above-mentioned uplink information is located, i.e., the time domain channel resource of the second time length.

[0211] At step S2106, the node device 102 sends the second indication information to the terminal 101.

[0212] In some embodiments, the second indication information is used to indicate at least one of:

[0213] suspending the decreasing of the random number by the first value;

[0214] resuming the decreasing of the random number by the first value;

[0215] adjusting a parameter value of the time-domain channel resource;

[0216] terminating the sending of the uplink information;

[0217] regenerating the random number.

[0218] Optionally, after receiving the second indication information, the terminal 101 can suspend the decreasing behavior of the random number.

[0219] Optionally, after receiving the second indication information, the terminal 101 can resume the decreasing behavior of the random number.

[0220] Optionally, the parameter value of the time-domain channel resource can be a Q value. After receiving the second indication information, the terminal 101 can regenerate the initial value of the random number.

[0221] Optionally, the second indication information can also indicate a new second time length T1 and / or a first time length T4. After receiving the second indication information, the terminal 101 can perform the decreasing behavior of the random number or perform the uplink sending according to the re-indicated T1 or T4 value.

[0222] Optionally, after receiving the second indication information, the terminal 101 can terminate the decreasing behavior of the random number and terminate the inventory process.

[0223] In some embodiments, the second indication information is used to control the communication of the terminal 101, such as the inventory process. For example, during the decreasing process of the random number, the node device 102 controls the terminal 101 to suspend, resume, adjust parameters, terminate, or restart, etc. through the second indication information.

[0224] In some embodiments, the node device 102 can send multiple control instructions through one signaling, or send the control instructions through different signalings respectively.

[0279] FIG. 4b is a flow diagram illustrating a method of receiving uplink information according to an embodiment of the present disclosure. As shown in FIG. 4b, the present disclosure relates to a method of receiving uplink information, which is performed by a node device 102, and the above method includes:

[0280] Step S4201, receiving the uplink information.

[0281] In some embodiments, the implementation of step S4201 can refer to the implementation of step S2104 in FIG. 2, which will not be repeated here.

[0282] The embodiments of the present disclosure propose an inventory method in an ambient IoT network. In the inventory process, the counter of the Device is decremented by itself according to the time interval configured by the network or defined by the protocol, avoiding the problems of missed detection and high resource overhead.

[0283] Optionally, the Device corresponds to the terminal 101 of the foregoing embodiments.

[0284] Optionally, in the embodiments of the present disclosure, the Device can obtain and maintain timing information. For example, the network needs to send a period or a semi-persistent synchronization signal.

[0285] To facilitate understanding of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure can include the following steps Step1-Step4:

[0286] Step1: The Device receives the first downlink signaling.

[0287] The first downlink signaling is used to start the first signaling (such as query) that starts the reporting process of the Device in the inventory process; and indicates the time domain channel resource parameter value Q of the Device, indicating that there are at most Q time domain channel resources.

[0288] Step2: The Device generates a counter initial value according to the first downlink signaling, 0 <= the initial value <= Q.

[0289] Step3: If the counter value of the Device is 0, the Device can send uplink information on the first time domain channel resource.

[0290] Optionally, if it is necessary to receive the acknowledgement information of the network node, the device receives the acknowledgement information on the first time domain signal resource. The acknowledgement information includes ACK or NACK, indicating whether the network node has received the uplink information of the Device.

[0291] The first time domain channel resource is a time domain channel with a time length of T1.

[0292] The time length of T1 is configured by the network or defined by the protocol. T1 can be configured by the first downlink signaling in Step1.

[0293] Wherein, the time length of T1 contains the time length of the device sending uplink information. In the case that the network node needs to send an acknowledgement, it also contains the time length of the network node sending an acknowledgement (including the interval between it and the uplink information).

[0294] Wherein, if the maximum time length of the device sending uplink information is T2 and the maximum time length of the network node sending an acknowledgement (including the interval between it and the uplink information) is T3, which are defined by the protocol or configured by the network, a possible embodiment is T1 = T2 + T3; another embodiment, in the case that no acknowledgement is needed, T1 = T2.

[0295] Step 4: If the counter value of the device is not 0, the device reduces the counter value by 1 every T4 time length, and when the counter is reduced to 0, it proceeds to Step 3.

[0296] Wherein, the time length of T1 is configured by the network or defined by the protocol. T1 can be configured by the first downlink signaling in Step 1.

[0297] Wherein, T4 >= T1. One embodiment is T4 = T1.
