[0033] Embodiments of the present disclosure provide a message processing method, a communication device, a communication system and a storage medium.

[0034] The first aspect provides a message processing method, wherein the method is performed by a first device, and the method comprises: the first device acquiring energy and discontinuously listening to a first message sent by a second device in a time domain; the first message is used at least for the second device triggering initial access of the first device.

[0035] According to the above scheme, after the first device acquires the energy, the first device changes the listening manner of continuously listening to the first message sent by the second device in the time domain. The first device will use discontinuous listening, thereby saving the energy of the first device and reducing the number of times of acquiring energy by the first device.

[0036] In some embodiments of the first aspect, discontinuously listening to the first message sent by the second device in the time domain comprises: after listening to the first message, discontinuously listening to the first message sent by the second device in the time domain.

[0037] According to the above scheme, after the first device acquires the energy, the first device enters discontinuous listening after listening to the first message sent by the second device. In this way, the relevant parameters of discontinuous listening are determined according to the first message listened to, for example, the size of the second time interval for discontinuously listening to the first message.

[0038] In some embodiments of the first aspect, listening to the first message comprises: continuously listening to the first message in a first time interval.

[0039] According to the above scheme, the first device continuously listens to the first message in the first time interval after acquiring the energy. If the first message is listened to in the first time interval, the listening is stopped. If the first message is not listened to in the first time interval, the listening is paused after the first time interval, and the start time of the next listening is determined or the listening is continued until the first message is listened to. In this way, even if the first device does not know the sending interval of the first message sent by the second device, the first message sent by the second device can be listened to as soon as possible.

[0040] In some embodiments of the first aspect, discontinuously listening to the first message sent by the second device in the time domain comprises: discontinuously listening to the first message in a second time interval according to the previous first message listened to.

[0041] According to the above scheme, it is specified how to discontinuously listen to the first message in the time domain, so as to save the energy consumption of the first device.

[0042] In some embodiments of the first aspect, the method further comprises: the sending interval of the first message is determined by a protocol; or the sending interval of the first message is determined according to the first message of the second device listened to.

[0043] According to the above scheme, the manner of acquiring the sending interval by the first device is specified, and in specific implementation, the manner is not limited to the above manner. In this way, the first device can acquire the sending interval in multiple manners, so as to be flexibly selected according to specific needs.

[0044] In some embodiments of the first aspect, the stopping, according to the last listened first message, from listening to the first message in the second time interval comprises: determining whether the second device transmits the first message in one or N next transmission time points according to the last listened first message, N being a positive integer greater than 1; and determining the second time interval according to whether the second device transmits the first message in one or N next transmission time points.

[0045] The above scheme specifically gives the first device listening to the first message transmitted by the second device, and clearly defines how to determine the second time interval according to the last first message.

[0047] The above scheme defines how the first device discontinuously listens to the first message transmitted by the second device in several specific scenarios, which can save the energy consumption of the first device as much as possible, and can also prevent the first device from missing the first message to be listened to.

[0048] In some embodiments of the first aspect, the stopping, according to the last listened first message, from listening to the first message in the second time interval comprises: determining the second time interval according to M indicated by the last first message; M being the number of transmission intervals between the next transmission of the first message by the second device and the last first message, and M being a positive integer.

[0049] In the above scheme, the first device can know the number of transmission intervals between the current transmission of the first message by the second device and the next transmission of the first message, and then the first device can determine the second time interval according to the number of transmission intervals.

[0050] In some embodiments of the first aspect, the determining the second time interval according to M indicated by the last first message comprises: determining the second time interval according to T2=M*P-x2; T2 being the second time interval, x2 being any positive number less than the transmission interval, and P being the transmission interval.

[0051] The second time interval is determined according to M based on the above scheme.

[0052] The second aspect provides a message processing method, wherein the method is performed by a second device, and the method comprises: sending a first message to a first device according to a sending interval; and the first message is used to trigger initial access of the first device.

[0053] In some embodiments of the second aspect, the first message is used to determine whether the second device sends the first message at one or more next sending time points; or the first message is also used to indicate M; the M is a number of sending intervals between a next sending time point of the second device and a previous sending time point of the first message; and the M is a positive integer.

[0054] In some embodiments of the second aspect, the first message is also used to indicate the sending interval.

Further, a plurality of systems can be combined (for example, LTE and NR can be combined).

[0094] The terminal 101 as illustrated in FIG. 1A can be any device that performs wireless communication for a backscattering transmission mechanism.

[0095] As shown in FIG. IB, the backscatter transmission mechanism can be a wireless communication mechanism using the principle of backscatter of radio frequency signals with a modulation and transmission technology of extremely low power consumption. The reader sends a physical layer signal to the ambient IoT device. The physical layer signal can be various alternating current signals such as pulse signals. In some embodiments, the physical layer signal is used to provide energy for the ambient IoT device to transmit signals. Therefore, the physical layer signal can be referred to as an excitation signal or a trigger signal. Exemplarily, when the excitation signal reaches the ambient IoT device, part of it will be reflected, and the ambient IoT device can adjust the matching between the receiving antenna and the impedance according to the information to be sent, enhance the reflection of the incident excitation signal, and modulate the perception data obtained by itself onto the reflected signal to complete the transmission of data. This process is similar to a mirror, and compared with other communication technologies, backscatter transmission does not require complex radio frequency structures, reduces the use of power amplifiers, high-precision crystal oscillators, duplexers, high-precision filters, and other devices, and does not require complex baseband processing, so it can simplify the design of the ambient IoT device and greatly reduce the cost of the ambient IoT device node. The ambient IoT device is an IoT device that can work in an environment. The environmental energy can include the signal energy of the aforementioned wireless signal, and can also include other environmental capabilities such as geothermal energy and / or light energy.

[0096] Backscatter communication has been widely used in radio frequency identification (RFID) systems, forming many commercial cases. The working principle is that the receiver (generally an RFID reader) sends a radio frequency excitation signal to activate a passive node (generally an RFID electronic tag), and the electronic tag modulates its own information onto the radio frequency signal using backscatter communication. The reader receives the reflection signal of the passive electronic tag and demodulates it to achieve information transmission.

[0097] Currently, FRID technology also has many shortcomings, such as small coverage distance (wireless signals in the communication process will experience double-path fading, so the path loss is large and the effective communication distance is short), single-channel transmission, the need for strict alignment of the tag, no power control, etc. There is a lot of room for improvement in the communication of RFID technology. It is necessary to integrate the third generation partnership project (3GPP) and the Internet of Things (IoT) to develop a new generation of wireless communication technology. rdGeneration Partnership Project, 3GPP) communication technology improves the wireless communication performance of RFID technology in the passive Internet of Things. This new type of Internet of Things device has the characteristics of low memory, low processing power, low power, small data transmission, and mass deployment. Ambient Internet of Things devices can be maintenance-free and have a long service life (e.g., more than 10 years). The new Internet of Things device needs to collect radio waves transmitted by network nodes to obtain energy to drive itself to work. Therefore, before obtaining energy, the Internet of Things device is usually in a "shutdown" state, i.e., a state of disconnection. Therefore, the communication system needs to support a data communication mode with shorter transmission time, lower memory consumption, and more convenient terminal management to complete the data communication process as soon as possible. The network topology architecture of backscatter transmission can include one of the following:

[0098] Topology architecture 1: As shown in FIG. 1C, ambient IoT devices and access network devices directly perform uplink (UL) and downlink (DL) data transmission;

[0099] Topology architecture 2: As shown in FIG. 1D, ambient IoT devices and access network devices indirectly perform DL and UL data transmission; intermediate nodes (or auxiliary nodes) exist for forwarding, for example, the intermediate node can be a relay, integrated access backhaul (IAB), user equipment (UE), repeater (RP).

[0100] Topology architecture 3: As shown in FIG. 1E, ambient IoT devices and access network devices directly perform DL or UL data reception or transmission; then there is an auxiliary node on the UL or DL, which is responsible for receiving or transmitting UL or receiving DL data. For example, the auxiliary node can be a relay, an integrated access backhaul (IAB) node, a terminal, a network-controlled repeater (NCR).

[0101] Topology architecture 4: As shown in FIG. 1F, ambient IoT devices and UEs directly perform DL and UL data reception and transmission; the UE is responsible for collecting data and forwarding the collected data to the network side.

[0102] Ambient IOT communication (i.e. communication between ambient IOT devices and base stations (topology architecture 1 as shown in FIG. 1C) and UEs (topology architecture 2 as shown in FIG. 1D)) can use spectrum resources in three forms: in-band, guard-band or stand alone.

[0103] In-band is to use the uplink and / or downlink spectrum resources of normal New Radio (NR) communication.

[0104] Guard-band is to use the spectrum resources of the guard band of the DL and / or UL spectrum of normal NR communication.

[0105] Stand alone is to use spectrum resources independent of normal NR communication.

[0106] As shown in FIG. 1G, devices using backscatter transmission mechanism for wireless communication can be divided into three types:

[0107] Device A: no energy storage, cannot independently generate signals and / or amplify signals, and can only perform backscatter transmission.

[0108] Device B: has energy storage, cannot independently generate signals, and can only perform backscatter transmission. The use of stored energy can include amplification of backscatter signals.

[0109] Device C: has energy storage and can independently generate signals, i.e. has active Radio Frequency (RF) components for transmission.

[0110] It should be noted that each device in FIG. 1G has two grids, where the first grid indicates whether the device has the ability to independently generate signals, and the second grid indicates whether the device has the ability to store energy. When the grid of a device is a grid without filling, it means that the device does not have the corresponding ability of the grid; when the grid of a device is a grid with filling, it means that the device has the corresponding ability of the grid.

[0111] In some embodiments, the following constraints are made for ambient IoT devices:

[0112] The first type of device has a peak power consumption of about 1 μW, has energy storage, and an initial sampling frequency offset (SFO) of up to 10X ppm; neither downlink amplification nor uplink amplification is available in the device. The uplink transmission of the device is backscattered on an externally provided carrier;

[0113] The second type of device, with peak power consumption less than or equal to a few hundred μW, has energy storage, and initial SFO up to 10X ppm; the device has downlink amplification and / or uplink amplification. The uplink transmission of the device can be generated internally by the device, or backscattered on an externally provided carrier. Wherein, X is determined by the working group.

[0114] In order to support the data transmission of ambient IoT devices, the following functions need to be supported in the network. One device in the network can support one or more functions. As the function of energy source (Energy Source, ES), only for device B and device C. Downlink transmission (Downlink Transmission, DT) function, send indication information to ambient IoT device, so as to trigger the uplink transmission of ambient IoT device. As the function of continuous wave (Continuous Wave, CW), only for device A and device B. Ambient IoT device realizes uplink transmission by backscattering CW. CW is actually also an ES, and ambient IoT device can receive CW and store energy. Uplink receiver (Uplink Receiver, UR) function, receive the uplink information backscattered by the ambient IoT device, or receive the uplink information actively transmitted by the ambient IoT device. The device performing the above ES, DT, CW or UR function can be UE, repeater or base station, etc. One device can only support one of the above functions. Alternatively, one device can also support multiple functions at the same time. Alternatively, one device can also support all the above functions at the same time.

[0115] The ambient IoT device can also be called a tag, and the device that reads information from the ambient IoT device can also be called an interrogator or a card reader, etc. In different scenarios, the ambient IoT device can transmit information based on different commands of other devices. Fig. 1H shows the interaction between the ambient IoT device and other devices in the inventory scenario, which can specifically include:

[0116] Step 1: The interrogator sends a command, which can include a query command, a query adjustment command or a query repetition command.

[0117] Step 2: Assuming that the random number is equal to 0, the tag sends the generated random number (RN16) to the interrogator, and if the random number is not equal to 0, the tag does not respond to the interrogator;

[0118] Step 3: The interrogator sends an ACK command carrying the random number;

[0119] Step 4: The tag receives the ACK command, determines the valid random number (is the random number generated by itself) and responds to the interrogator, otherwise it does not respond;

[0120] Step 5: the interrogator sends a repeat sending ACK command carrying a repeated random number;

[0121] Step 6: the tag receives the ACK command, determines a valid random number (the random number generated by itself) to respond to the interrogator, or does not respond otherwise;

[0122] Step 7: the interrogator accesses the tag using the handle as a parameter. Step 8: the tag verifies the handle.

[0123] The above is only an example of communication between an environmental Internet of Things device and other devices, and the specific implementation is not limited to the above example.

[0124] As shown in FIG. 2, the embodiment of the present disclosure provides a message processing method, which is executed by the communication system shown in FIG. 1A. The method can include:

[0125] S2101: The second device sends a first message to the first device.

[0126] In some embodiments, the second device can be an access network device or a user equipment, etc. Illustratively, the second device can be various electronic devices or communication devices which can store power by themselves or are stably connected to a power supply system.

[0127] In some embodiments, the second device sends the first message according to a sending interval. Illustratively, the sending interval can be understood as a sending period of the first message.

[0128] In some embodiments, the second device determines a sending time at which the first message can be sent according to the sending interval, and sends or does not send the first message at the sending time according to needs. The time interval between two adjacent sending times is the sending period. For example, if the second device has a demand to page the first device, the second device can send the first message at the next or multiple sending times, or does not send the first message at the next or multiple sending times. In some embodiments, the second device receives a sending instruction from another device, and sends the first message at the next or multiple sending times, or does not send the first message at the next or multiple sending times.

[0129] In some embodiments, the first message is used to enable the first device to access the second device. Illustratively, the first message can be used for initial access of the first device. Illustratively, the first message can be used for the second device to trigger initial access or random access of the first device.

[0130] In some embodiments, the first message can be a paging message or an initial trigger message.

[0131] In some embodiments, the first device enters a stage of listening to downlink command from the second device after receiving the first message sent by the second device. For example, if the first device is a device to be inventoried in an inventorying scenario, the first device can enter a stage as shown in FIG. 1H after receiving the first message.

[0132] In some embodiments, the first message can be used by the first device to determine whether the second device will send the first message at the next or more sending time.

[0133] In some embodiments, the first message is also used to indicate M. M can be the number of sending intervals. That is, M represents the number of sending intervals between the current sending of the first message by the second device and the next sending of the first message by the second device. The first device determines the number of sending intervals M of the next sending of the first message by the second device. In some embodiments, M can be a natural number, i.e., M can be 0 or a positive integer.

[0134] In some embodiments, the first message is also used to indicate the sending interval.

[0135] For example, the first message can include one or more fields, and different fields can carry different contents. One or more fields predetermined to be carried by the first message can or can not be carried.

[0136] For example, the first message can carry a first field and a second field. The first field can be used to indicate whether the second device will send the first message at the next or more sending time. Alternatively, the first field can be used to indicate the time interval of the next sending of the first message by the second device. For example, the first field can also be an optional field. If the first message does not carry the first field, it can be considered that the second device will send the first message at the next or more sending time. If the first message carries the first field, the sending time of the next sending of the first message by the second device is determined according to the first field, or the sending time of the non-sending of the first message by the second device is determined according to the first field.

[0137] For another example, the second field can be used to indicate the sending interval. Of course, the second field can be an optional field. For example, if the protocol stipulates the sending interval, the second field is an optional field. Alternatively, the second field can indicate a time interval different from the sending interval stipulated by the protocol. In this case, after receiving the first message, the first device finds that the first message includes the second field, and then determines the sending interval of the first message according to the second field, otherwise, the first device determines the time interval of the sending of the first message by the second device according to the protocol stipulation.

[0138] It is worth noting that in the embodiments of the present disclosure, the first message is a general indication of a certain type of message, and is mainly used for the message for enabling the first device to access, and is not a specific indication of a certain message. For example, the first message can be a message for enabling the first device to initially access or randomly access.

[0139] S2102: The first device discontinuously monitors the first message sent by the second device.

[0140] In some embodiments, the first device can include, but is not limited to, the aforementioned environmental Internet of Things device.

[0141] In some embodiments, the first device obtains energy and discontinuously monitors the first message sent by the second device in the time domain. The first device can obtain energy in various ways, such as obtaining solar energy or geothermal energy or environmental energy based on communication signal transmission. Here, the first device obtains energy to provide the energy consumption required for the operation of the first device.

[0142] In some embodiments, the first device obtains energy and discontinuously monitors the first message sent by the second device in the time domain.

[0143] In some embodiments, after the first device obtains energy, the first device monitors the first message sent by the second device with the energy. In the embodiments of the present disclosure, in order to save the energy of the first device and reduce the number of energy charging and discharging of the first device, the first device discontinuously monitors the first message sent by the second device in the time domain, rather than continuously monitors the first message sent by the second device.

[0144] In some embodiments, after monitoring the first message sent by the second device, the first device discontinuously monitors the first message sent by the second device in the time domain.

[0145] In some embodiments, after the first device monitors the first message sent by the second device, the first device discontinuously monitors the first message sent by the first device in the time domain. For example, after the first device obtains energy and monitors the first message sent by the second device, the first device discontinuously monitors the first message sent by the first device in the time domain.

[0146] In some embodiments, the first device discontinuously monitors the first message in the time domain according to the sending interval of the first message. For example, the monitoring of the first message is stopped in part or all of the time between two sending intervals. In some embodiments, if the sending interval of the first message sent by the second device is not agreed in the protocol, or if the sending interval of the first message sent by the second device may change although the sending interval of the first message sent by the second device is agreed in the protocol, the first device discontinuously monitors the first message sent by the first device in the time domain after obtaining energy and after monitoring the first message sent by the second device.

[0147] In some embodiments, if the protocol specifies the transmission interval of the first message transmitted by the second device and the starting time of the first message, or the first device determines the preconfigured transmission interval and the configured starting time to listen to the first message, the first device can start to listen to the first message before the next transmission time according to the time information of the current time and the transmission time corresponding to the expected transmission interval after obtaining the energy. In this scenario, even if the first device is listening to the first message of the second device, it can also be discontinuous listening.

[0148] In some embodiments, the first device listening to the first message includes continuously listening to the first message in the first time interval. In some embodiments, the first device continuously listens to the first message in the first time interval, and after the first device listens to the first message in the first time interval, the first device stops continuously listening to the first message in the first time interval, and the first device obtains energy.

[0149] In some embodiments, the first device continuously listens to the first message transmitted by the second device in the first time interval after the first device obtains energy until the first time interval stops, or until the first device listens to the first message.

[0150] In some embodiments, the first time interval can be set according to the transmission interval of the first message. In this case, the first device can know the possible transmission interval of the first message transmitted by the second device in advance. For example, the protocol specifies multiple alternative possible transmission intervals, the first device knows the alternative transmission intervals specified by the protocol, but does not know the specific transmission interval used by the second device, in which case the first time interval can be set according to the maximum time interval in the alternative transmission intervals. If the first device knows the transmission interval of the first message transmitted by the second device after obtaining the energy, it is preferred to set the first time interval to be greater than the transmission interval of the first message, so that the first device can listen to the first message as soon as possible after obtaining the energy.

[0151] For example, the first device continuously listens to the first message transmitted by the second device in the first time interval after obtaining the energy, and after listening to the first message, the first device stops continuously listening to the first message in the first time interval and enters a discontinuous listening state.

[0152] In some embodiments, the first time interval can also be a randomly set time interval. In this case, the first device can randomly generate the first time interval, without knowing the possible time interval of the first message sent by the second device, but considering that the communication can not be urgent. If no first message is heard within the set first time interval, the first device stops listening for a period of time, and then sets a first time interval again to continue listening until the first message sent by the second device is heard. Alternatively, if no first message is heard within the set first time interval, the first device extends the first time interval to continue listening until the first message is heard.

[0153] In some embodiments, the sending interval of the first message is determined according to a protocol, or is determined according to the first message of the second device heard. That is, there are at least two ways for the first device to determine the sending interval, which are as follows:

[0154] Method one: the sending interval of the first message is determined according to a protocol.

[0155] Method two: the sending interval of the first message is determined according to the first message of the second device heard.

[0156] Exemplarily, the sending interval is determined according to the first message of the second device heard. The sending interval is determined according to the previous first message of the second device heard. In some embodiments, if the first message sent by the second device includes a specific time point (for example, a first time point) at which the second device will send the first message next time, the first device directly stops listening for the first message between the current time point and a second time point, and starts listening for the first message between the second time point and the first time point. The second time point is later than the current time point and earlier than the first time point. In this case, the energy consumption of the first device for continuous listening can be reduced as much as possible. In some embodiments, the first device acquires energy and discontinuously listens for the first message sent by the second device in the time domain after the first message sent by the second device is heard.

[0157] In some embodiments, according to the previous first message heard, the first device stops listening for the first message within a second time interval. Exemplarily, the first device determines the time period for stopping listening in the discontinuous listening state according to the previous first message heard. The time period for stopping listening is the second time interval.

[0158] In some embodiments, according to the previous first message heard, the first device determines whether the second device will send the first message at one or N sending time points in the future, N being a positive integer greater than 1; and determines the second time interval according to whether the second device will send the first message at the one or N sending time points in the future.

[0159] In some embodiments, the second device transmits the first message at a next transmission time, and determines that the second time interval is less than the transmission interval.

[0160] In some embodiments, the second device does not transmit the first message at a next transmission time, and determines that the second time interval is less than twice the transmission interval. Exemplarily, in this case, the second time interval will also be greater than the transmission interval, so that the energy consumption of the first device can be possibly saved.

[0161] In some embodiments, the second device does not transmit the first message at N next transmission times, and determines the second time interval according to T2= (N+1) *P-x1; the T2 is the second time interval; and the x1 is any positive number less than the transmission interval.

[0162] In some embodiments, N can be a positive integer, or N can be a positive integer greater than or equal to 2.

[0163] In some embodiments, T2>N*P. If T2>N*P, the first device can be prevented from missing the first message that needs to be listened to, and the success rate of the first device listening to the first message can be ensured.

[0164] In some embodiments, the second time interval is determined according to M indicated by a previous first message; the M is the number of transmission intervals between the next transmission of the first message by the second device and the previous first message, and the M is a positive integer. In this case, the second time interval is determined according to M indicated by the previous first message, including: determining the second time interval according to T2=M*P-x2; the T2 is the second time interval, the x2 is any positive number less than the transmission interval, and the P is the transmission interval.

[0165] In some embodiments, T2>M*P. If T2>M*P, the first device can be prevented from missing the first message that needs to be listened to, and the success rate of the first device listening to the first message can be ensured.

[0166] As shown in FIG. 3, the embodiment of the disclosure provides a message processing method, wherein the method is performed by a first device. The method can include:

[0167] S3101: acquiring energy;

[0168] S3102: discontinuously listening to a first message in a time domain.

[0169] In some embodiments, the first device discontinuously listens to the first message transmitted by a second device in a time domain.

[0170] In some embodiments, the first device acquires energy and discontinuously monitors the first message sent by the second device in time domain. Illustratively, after the first device acquires energy, the first device discontinuously monitors the first message sent by the second device in time domain.

[0171] In some embodiments, the first message is used for enabling the first device to access. Illustratively, the first message is used for enabling initial access of the first device.

[0172] In some embodiments, the optional real-time manner of S3102 can refer to any optional implementation manner of S2102 of the corresponding embodiment of FIG. 2.

[0173] As shown in FIG. 4, the embodiment of the present disclosure provides a message processing method, wherein the method is performed by a second device. The method can include:

[0174] S4101: determining a sending interval;

[0175] Illustratively, the second device determines the sending interval according to a protocol.

[0176] Illustratively, the second device determines the sending interval according to a data acquisition requirement or a paging requirement.

[0177] It is worth noting that the step of determining the sending interval is an optional step. For example, the second device can use a default sending interval when sending the first message, and the step can be skipped.

[0178] S4102: sending a first message.

[0179] In some embodiments, the second device sends the first message according to the sending interval.

[0180] In some embodiments, the second device determines a sending time according to the sending interval. The first message is sent at one or more sending times.

[0181] In some embodiments, the second device sends the first message to the first device.

[0182] In some embodiments, the first message is used for enabling the first device to access. Illustratively, the first message is used for enabling the first device to access the second device. Illustratively, the first message is used for triggering initial access or re-access of the first device to the second device.

[0183] In some embodiments, the first message is further used for the first device to determine whether the second device sends the first message at the next one or more sending times.

[0184] In some embodiments, the first message includes M. M indicates the number of sending intervals between adjacent two times of sending the first message by the second device.

[0185] In some embodiments, the first message is further used to indicate the sending interval.

[0186] In some embodiments, the sending time at which the first message can be sent is determined according to the sending interval, and at the corresponding sending time, the first message is sent or not sent according to the demand.

[0187] The optional real-time manner of S4102 can refer to any optional implementation manner of S2101 of the corresponding embodiment of FIG. 2.

[0188] In some cases, after the environment capable Internet of Things device or the like acquires power, it needs to listen to a paging message, and determines whether to be triggered to access the network through the listening to the paging message. If the device maintains listening to the message after acquiring power, it will waste the power of the device and make the device frequently discharge and charge.

[0189] In the embodiments of the present disclosure, the device can also perform discontinuous listening to the paging message after charging, so as to save the power of the device as much as possible, reduce the number of charging and discharging, and improve the working performance of the device. Exemplarily, the paging message here is one of the first messages.

[0190] The network side (reader side) issues a paging message at a time domain position determined according to a paging cycle, for example, assuming that the sending interval is 10 ms. The position of the first paging time is determined based on the implementation of the network side, for example, the network side determines randomly. However, the next paging time at which the paging message can be sent is determined according to 10 ms. Exemplarily, the network side can correspond to the second device. The paging time here can correspond to the sending time. The paging cycle can correspond to the sending interval.

[0191] As shown in FIG. 5, after the device is charged, it starts to listen to the paging message, and the time window for listening to the paging message is greater than or equal to the time interval at which the network side issues the paging message, for example, 12 ms. In this way, it is ensured that the device can listen to a paging time. Exemplarily, after the device 1 acquires energy, it continuously listens to the paging message in the time window 1, and after listening to a paging message, it starts to perform discontinuous listening to the subsequent paging message according to the listened paging message. After the device 2 acquires energy, it continuously listens to the paging message in the time window 2, and after listening to a paging message, it performs discontinuous listening to the subsequent paging message according to the listened paging message. Exemplarily, the paging time here corresponds to the sending time.

[0192] Option 1: If the device listens to a paging message, the device stops listening to the paging message. If it is indicated that no paging message is sent at the next paging time, the device starts a timer, and the length of the timer is less than 2 times the length of the paging interval time, for example, if the sending period (i.e., the sending interval) of the paging message is 10 ms, the length of the timer can be set to 18 ms. During the running of the timer, the device does not listen to the network. When the timer expires, the device starts to listen to the paging message again.

[0193] Option 2: If the device listens to a paging message, the device stops listening to the paging message. If it is indicated that a paging message is sent at the next paging time, the device starts a timer. The length of the timer is less than the paging period, for example, 8 ms. During the running of the timer, the device does not listen to the network. When the timer expires, the device starts to listen to the paging message again.

[0194] Option 2:

[0195] The network side (reader side) sends the paging message according to the position of the period, for example, the sending interval of the paging message is 10 ms. The time position of the first paging time is determined based on the network side implementation, but the time position of each time at which the paging message can be sent is determined according to 10 ms.

[0196] The device starts to listen to the paging message after being charged. The time window in which the device listens to the paging message is greater than or equal to the time interval in which the network side sends the paging message, for example, 12 ms. In this way, it is ensured that the device can listen to a paging time.

[0197] Option 1: If the device listens to a paging message, the device stops listening to the paging message. If it is indicated that no paging message is sent at the next paging time, the device starts a timer, and the length of the timer is less than 2 times the length of the paging interval time, for example, if the sending period (i.e., the sending interval) of the paging message is 10 ms, the length of the timer can be set to 18 ms. During the running of the timer, the device does not listen to the network. When the timer expires, the device starts to listen to the paging message again.

[0198] The disclosure embodiments can enable the device to perform discontinuous paging reception after being charged, and thus save power as much as possible, reduce the number of charging and discharging, and improve the working performance of the device.

[0199] In the embodiments of the disclosure, part or all of the steps, and optional implementation manners thereof, can be combined with part or all of the steps in other embodiments, or can be combined with optional implementation manners of other embodiments.

[0200] In the embodiments of the present disclosure, part or all of the steps, and optional implementation manners thereof, can be combined with part or all of the steps in other embodiments, or combined with optional implementation manners of other embodiments.

[0201] The embodiments of the present disclosure further provide a device for implementing any of the above methods, for example, providing a device, the device comprising units or modules for implementing the steps performed by the UE in any of the above methods. For another example, another device is provided, comprising units or modules for implementing the steps performed by the network device (for example, an access network device, or a core network device, etc.) in any of the above methods.

[0202] It should be understood that the division of units or modules in the above device is only a logical functional division, and all or part of them can be integrated into one physical entity, or physically separated. In addition, the units or modules in the device can be implemented in the form of processor calling software: for example, the device includes a processor, the processor is connected with a memory, the memory stores instructions, and the processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules of the device, wherein the processor is, for example, a general processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory in the device or a memory outside the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuit, and the functions of part or all of the units or modules can be implemented by the design of hardware circuit, and the hardware circuit can be understood as one or more processors; for example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC), and the functions of part or all of the units or modules are implemented by the design of the logical relationship between the elements in the circuit; for another example, in another implementation, the hardware circuit is a programmable logic device (PLD), and taking a field programmable gate array (FPGA) as an example, it can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by a configuration file, so as to implement the functions of part or all of the units or modules. All units or modules of the above device can be implemented in the form of processor calling software, or all units or modules can be implemented in the form of hardware circuit, or part of the units or modules can be implemented in the form of processor calling software, and the remaining part can be implemented in the form of hardware circuit.

[0203] In the embodiments of the present disclosure, the processor is a circuit with signal processing capability. In one implementation, the processor can be a circuit with instruction reading and running capability, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), a digital signal processor (DSP), and the like. In another implementation, the processor can implement certain functions through a logical relationship of a hardware circuit, and the logical relationship of the hardware circuit is fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In the reconfigurable hardware circuit, the processor loads a configuration document to implement the configuration of the hardware circuit. It can be understood that the processor loads an instruction to implement the functions of the above part or all units or modules. In addition, the hardware circuit can also be designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), and the like.

[0204] As shown in FIG. 6A, the embodiments of the present disclosure provide a first device, comprising:

[0205] The processing module 6101 is configured to enable the first device to acquire energy and discontinuously monitor a first message sent by a second device in a time domain; and the first message is used at least for the second device to trigger initial access of the first device.

[0206] In some embodiments, the first device further comprises a sending module and a receiving module. The sending module and / or the receiving module can correspond to a network interface and / or a transceiving antenna of the first device.
