[0122] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated.

It should also be understood that the term "and / or" as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0124] It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present disclosure, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first indication information may also be referred to as the second indication information, and similarly, the second indication information may also be referred to as the first indication information. Depending on the context, the words "if" and "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0125] In some possible implementations, the names of information, etc. are not limited to the names described in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codeword", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0126] The embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be understood as limiting the present disclosure.

[0127] As shown in Figure 1, the method provided in the embodiment of the present disclosure can be applied to a wireless communication system 100, which may include a terminal 101 and a network device 102. It should be noted that the wireless communication system 100 may also include other devices, and this application does not limit the devices included in the wireless communication system 100.

[0128] It should be understood that the above wireless communication system 100 is applicable to both low-frequency scenarios and high-frequency scenarios. Application scenarios of the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for micro wave access (WiMAX) communication systems, cloud radio access networks (CRAN) systems, future fifth-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile networks (PLMN) systems, Internet of Things systems, etc.

[0129] The terminal 101 shown above may be a terminal, an access terminal, a terminal unit, a terminal station, a mobile station (MS), a remote station, a remote terminal, a mobile terminal, a wireless communication device, a terminal agent, an Internet of Things terminal, etc. The terminal 101 may have wireless transceiver capabilities, and may be capable of communicating (e.g., wirelessly communicating) with one or more network devices of one or more communication systems and receiving network services provided by the network devices, where the network devices include but are not limited to the illustrated network device 102.

[0130] Among them, the terminal 101 can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal in a future 5G network, or a terminal in a future evolved PLMN network, etc.

[0131] Terminal 101 may also be an Internet of Things (IoT) terminal. IoT terminals have lower complexity, manufacturing costs, and maintenance costs than conventional terminals. IoT terminals may not require batteries and instead receive power from electromagnetic signals. IoT terminals may also include a battery with a small amount of electrical storage capacity. This battery does not require manual charging, but instead obtains energy from external sources, such as electromagnetic waves, thermal energy, kinetic energy, and so on.

[0132] In the implementation of the present disclosure, different terminals have different capabilities. For example, different terminals have different types and working modes, and their power acquisition and storage capabilities may also be different.

[0133] The capabilities of the first type of terminal include: no energy storage capability, and no independent signal generation or amplification.

[0134] In one example, the first terminal uses a backscattering working mode.

[0135] The capabilities of the second type of terminal include: energy storage capability, and inability to generate independent signals.

[0136] In one example, the second terminal may use a backscattering working mode, and may also use the stored energy to amplify the reflected signal.

[0137] The capabilities of the third type of terminal include: energy storage capability and the ability to independently generate signals.

[0138] In one example, the third type of terminal has a radio frequency (RF) module that actively sends signals.

[0139] Of the three types of terminals mentioned above, the third type offers the strongest capabilities but the highest cost. The first type offers the weakest capabilities but the lowest cost. Furthermore, since the first and second types of terminals can only operate in backscatter mode and cannot actively transmit signals, their supported coverage range is smaller. However, their operating modes consume less power than the third type.

[0140] In one example, terminal 101 is an Ambient-IoT. Ambient-IoT uses backscatter communications technology, which is one of the key technologies for building a green, energy-saving, low-cost, and flexibly deployable future Internet of Things and an important means to achieve "intelligent connectivity of all things."

[0141] Backscatter communication utilizes the principle of RF signal backscattering to develop an extremely low-power modulation and transmission technology. Since a portion of the RF signal is reflected when it reaches the surface of an object, the transmitting node adjusts the matching between the receiving antenna and the impedance according to the intended information, enhancing the reflection of the incident RF signal. It then modulates the acquired sensory data onto the reflected signal to complete the data transmission. This process is similar to that of a reflector. Compared to other communication technologies, backscatter communication does not require complex RF structures, reducing the use of components such as power amplifiers, high-precision crystal oscillators, duplexers, and high-precision filters. It also does not require complex baseband processing, thus simplifying terminal design and significantly reducing terminal node costs.

[0142] In the implementation of the present disclosure, in large-scale cargo inventory (for example, applied in logistics ports), each smallest unit of cargo is attached with an ambient IoT, and the network device determines the arrival of the cargo by detecting the presence of the ambient IoT.

[0143] In the implementation of this disclosure, in scenarios involving massive amounts of cargo identification, when a large number of ambient IoT devices send information to network devices, the probability of network congestion is high, and it takes a considerable amount of time for network devices to obtain the label information of all the goods. In such scenarios, it is necessary to consider how to enable network devices to obtain cargo information in the shortest possible time, thereby reducing information transmission time and improving information transmission speed.

[0144] FIG2 is an interactive schematic diagram of a communication method provided according to an embodiment of the present disclosure. As shown in FIG2 , the method includes the following steps:

[0145] Step S2101 , the network device 102 sends first information to the terminal 101 .

[0146] In some possible implementations, the terminal 101 receives first information.

[0147] In some possible implementations, the name of the first information is not limited, for example, it is "indication information", "configuration information", etc.; the name of the resource pool is not limited, for example, it is "channel resource pool", "channel resource pool", etc.

[0148] In some possible implementations, when the terminal 101 accesses the network device 102 to perform network registration, the network device 102 sends first information to the terminal 101 .

[0149] In some possible implementations, the first information is used to indicate the channel type and / or channel quantity in the resource pool. Optionally, the network device 102 creates the resource pool.

[0150] In some possible implementations, the first information is used to indicate the channel type in the resource pool. Optionally, the number of channels is determined based on a protocol agreement.

[0151] In some possible implementations, the first information is used to indicate the number of channels in the resource pool. Optionally, the channel type is determined based on a protocol agreement.

[0152] In some possible implementations, the channel type includes at least one of the following: a time domain channel, a frequency domain channel, and a code domain channel.

[0153] In one example, each time domain unit in the time domain is a time domain channel, each frequency domain unit in the frequency domain is a frequency domain channel, and each spreading code in the code domain is a code domain channel.

[0154] In one example, the first information indicates that the resource pool includes N time domain channels, M frequency domain channels, and K code domain channels, where N, M, and K are integers of 0.

[0155] In some possible embodiments, the first information further includes a first value, where the first value is the number of channels in the first resource.

[0156] In some possible embodiments, the first resource is used by the terminal 101 to send information to the network device 102 .

[0157] In some possible embodiments, the first resource includes some channels in a resource pool.

[0158] In some possible embodiments, the channel included in the first resource belongs to a resource pool.

[0159] In one example, the first resource includes n time domain channels, m frequency domain channels and k code domain channels, where n is an integer less than or equal to N, m is an integer less than or equal to M, and k is an integer less than or equal to K.

[0160] Step S2102 , the network device 102 sends first indication information to the terminal 101 .

[0161] In some possible implementations, the first indication information is used to indicate the first mode.

[0162] In some possible implementations, the first method is a method of determining a first resource in a resource pool.

[0163] In one example, the first method is: randomly selecting a first resource in the resource pool.

[0164] In one example, the first method is to determine the first resource in the resource pool according to at least one of a device index of the terminal 101 and a random number. Optionally, the device index of the terminal 101 is a device ID of the terminal.

[0165] In step S2103, the terminal 101 determines the first mode.

[0166] In some possible implementations, the terminal 101 determines the first mode according to the first indication information.

[0167] In some possible implementations, the terminal 101 determines the first mode according to a protocol agreement.

[0168] In some possible implementations, the terminal 101 determines the first mode according to its own communication situation.

[0169] Step S2104: Terminal 101 determines the first resource in the resource pool.

[0170] In some possible implementations, the first resource is used to send the second information to the network device 102 , and the first resource includes at least one channel.

[0171] In some possible implementations, a first resource in a resource pool is determined according to a first approach.

[0172] In some possible implementations, the name of the first resource is not limited, for example, it may be "channel resource".

[0173] Step S2105 , the network device 102 sends second indication information to the terminal 101 .

[0174] In some possible embodiments, the second indication information is used to indicate the second mode.

[0175] In some possible embodiments, the second manner is a manner of sending the second information on the first resource.

[0176] In one example, the second manner is: repeatedly sending the second information on multiple channels of the first resource, wherein the number of repeated transmissions is less than or equal to the first value.

[0177] In one example, the second mode is to send the second information on the first resource at the first code rate. Optionally, the first code rate is less than the second code rate, and the second code rate is the maximum code rate for sending the second information on any channel on the first resource. Optionally, the second code rate is the product of the first code rate and the number of channels in the first resource, that is, second code rate = first code rate * number of channels in the first resource.

[0178] In step S2106, the terminal 101 determines the second method.

[0179] In some possible implementations, the terminal 101 determines the second mode according to the second indication information.

[0180] In some possible implementations, the terminal 101 determines the second mode according to a protocol agreement.

[0181] Step S2107 , the network device 102 sends third indication information to the terminal 101 .

[0182] In some possible implementations, the third indication information is used to indicate a third mode.

[0183] In some possible implementations, the third manner is a distribution manner of the first resource.

[0184] The third method is one of the following:

[0185] Different channels have different time domain positions but the same frequency domain positions and correspond to the same spreading code;

[0186] Different channels have different frequency domain positions but the same time domain positions and correspond to the same spreading code;

[0187] Different channels have the same time domain position and frequency domain position and correspond to different spreading codes.

[0188] In one example, the third manner is: different channels have different time domain positions, the same frequency domain positions, and the same spreading codes corresponding to the different channels.

[0189] In one example, the third manner is: the frequency domain positions of different channels are different, the time domain positions of different channels are the same, and the spreading codes corresponding to different channels are the same.

[0190] In one example, the third manner is: different channels correspond to different spreading codes, the time domain positions of different channels are the same, and the frequency domain positions of different channels are the same.
