[0034] Embodiments of the present disclosure provide a communication method, a terminal, a network device, and a storage medium.

[0035] In a first aspect, an embodiment of the present disclosure provides a communication method, applied to a terminal, the method comprising:

[0036] Sending first information to the network device through N channels; the N channels are one or more of the M channels; wherein N and M are both integers greater than 0;

[0037] Second information sent by the network device is received, where the second information is used to indicate feedback information of the network device on the N channels with respect to the first information.

[0038] In the above embodiment, the network device sends feedback information to the N channels through which the terminal sends the first information. Compared with sending feedback information to each terminal separately, signaling overhead can be reduced.

[0039] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0040] The second information includes M pieces of feedback information, wherein each piece of feedback information corresponds to one of the M channels.

[0041] In the above embodiment, the network device sends feedback information uniformly for all channels in the resource pool. Compared with sending feedback information for each terminal separately, there is no need to carry the terminal identifier in the feedback information, which can reduce signaling overhead, especially in the usage scenario of massive terminals.

[0042] In combination with some embodiments of the first aspect, in some embodiments, the terminal determines the feedback information of the network device for the first information on the N channels from M feedback information in the second information based on the N channels.

[0043] In the above embodiment, the terminal can accurately extract the feedback information for itself from the second information according to the channel corresponding to the first resource.

[0044] In conjunction with some embodiments of the first aspect, in some embodiments, the M channels include one or more groups, each group including K channels of the M channels, where K is an integer greater than 1 and less than or equal to N;

[0045] The second information includes first feedback information of one or more groups, wherein the first feedback information of each group is used to indicate feedback information of the network device on K channels in each group.

[0046] In the above embodiment, by returning feedback information in a grouped manner, signaling overhead can be saved.

[0047] In combination with some embodiments of the first aspect, in some embodiments, the first feedback information of each group is a logical AND of feedback information of K channels in each group.

[0048] In the above embodiment, the first feedback information of each group is determined by means of logical AND, which can effectively reflect the feedback information of multiple channels in each group while saving signaling overhead.

[0049] In combination with some embodiments of the first aspect, in some embodiments, when the first feedback information of the first group indicates that the network device has not successfully received the K channels of the first group, the second information also includes second feedback information of the first group; wherein the second feedback information of the first group indicates the feedback information of each channel in the first group; wherein the first group is a group in the M channels.

[0050] In the above embodiment, when multiple channels share one feedback information, while sending feedback information for each channel in the resource pool, feedback information on each single channel is also returned for multiple channels corresponding to each feedback information indicating denial. Therefore, the information returned by the network device to the terminal includes information of two granularities, the first being coarse-grained information and the second being fine-grained information. While saving signaling overhead by sharing one feedback information for multiple channels, feedback information of each channel can also be accurately indicated for the channel that failed to receive. This saves signaling overhead while ensuring accurate feedback on the channel that failed to receive.

[0051] In combination with some embodiments of the first aspect, in some embodiments, the terminal determines, based on the N channels, from the second information, first feedback information of the group to which the N channels belong.

[0052] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0053] When the first feedback information of the second group indicates that the network device successfully receives on K channels of the second group, the terminal determines that the network device successfully receives on a channel belonging to the second group among the N channels, where the second group is one group among the N channels.

[0054] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0055] When the first feedback information of the third group indicates that the network device has not successfully received all K channels of the third group, the terminal determines the feedback information of the network device on the channels belonging to the third group among the N channels based on the second feedback information of the third group, where the third group is one group among the N channels.

[0056] In combination with some embodiments of the first aspect, in some embodiments, the first feedback information and the second feedback information in each group are encoded separately.

[0057] In the above embodiment, the non-fixed number of bits of the second feedback information can be used to accurately divide different data and avoid data confusion.

[0058] With reference to some embodiments of the first aspect, in some embodiments, the first feedback information is decoded according to a first method, where the first method corresponds to a method of encoding the first feedback information;

[0059] The second feedback information is decoded according to the first feedback information and a second method, where the second method corresponds to a method of encoding the second feedback information.

[0060] In conjunction with some embodiments of the first aspect, in some embodiments, sending the first information to the network device through N channels includes:

[0061] Each of the N channels transmits the first information; the method further comprising:

[0062] When the second information indicates that the feedback information of the first information on any one of the N channels is successfully received by the network device, it is determined that the network device has successfully received the first information.

[0063] In the above embodiment, the terminal repeatedly sends the first information on multiple channels, which can improve the effectiveness of information transmission. When the terminal determines whether the network device has received the information successfully, it only needs to determine the feedback information corresponding to one channel, which can save the processing power of the terminal.

[0064] In conjunction with some embodiments of the first aspect, in some embodiments, sending the first information to the network device through N channels includes:

[0065] The first information is transmitted jointly through the N channels, and different parts of the first information are transmitted on different channels among the N channels; the method further comprising:

[0066] When the second information indicates that the feedback information of the network device regarding the first information on any one of the N channels is not successfully received, it is determined that the network device has not successfully received the first information.

[0067] In the above embodiment, sending different parts of the first information on multiple different channels can improve the flexibility of the sending method. Whether different parts are successfully received can accurately know the feedback information of each part, and different feedback information of different parts can be applied to various possible subsequent processing.

[0068] In a second aspect, an embodiment of the present disclosure provides a communication method, applied to a network device, the method comprising:

[0069] receiving first information sent by a terminal through N channels; the N channels are one or more of the M channels; wherein N and M are both integers greater than 0;

[0070] Second information is sent to the terminal, where the second information is used to indicate feedback information of the network device on the N channels with respect to the first information.

[0071] In combination with some embodiments of the first aspect, in some embodiments, the second information includes M feedback information, wherein each feedback information corresponds to one channel among the M channels.

[0072] In conjunction with some embodiments of the first aspect, in some embodiments, the M channels include one or more groups, each group including K channels of the M channels, where K is an integer greater than 1 and less than or equal to N;

[0073] The second information includes first feedback information of one or more groups, wherein the first feedback information of each group is used to indicate feedback information of the network device on K channels in each group.

[0074] In combination with some embodiments of the first aspect, in some embodiments, the first feedback information of each group is a logical AND of feedback information of K channels in each group.

[0075] In combination with some embodiments of the first aspect, in some embodiments, the first feedback information of the first group indicates that when the network device fails to successfully receive on the K channels of the first group, the second feedback information of the first group is determined, and the second feedback information indicates the feedback information of each channel in the first group.

[0076] In combination with some embodiments of the first aspect, in some embodiments, when the first feedback information of the first group indicates that the network device has not successfully received the K channels of the first group, the second information also includes second feedback information of the first group; wherein the second feedback information of the first group indicates the feedback information of each channel in the first group; wherein the first group is a group in the M channels.

[0077] In combination with some embodiments of the first aspect, in some embodiments, the first feedback information and the second feedback information of each group are independently encoded.

[0078] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0079] encoding the first feedback information according to a first manner, where the first manner corresponds to a manner in which the first feedback information is encoded;

[0080] The second feedback information is encoded according to the first feedback information and a second method, where the second method corresponds to the method of encoding the second feedback information.

[0081] In a third aspect, an embodiment of the present disclosure provides a terminal, including:

[0082] A transceiver module is configured to send first information to the network device through N channels; the N channels are one or more of the M channels; wherein N and M are both integers greater than 0;

[0085] a transceiver module configured to receive first information sent by a terminal through N channels; the N channels are one or more of the M channels; wherein N and M are both integers greater than 0;

[0086] The device is further configured to send second information to the terminal, where the second information is used to indicate feedback information of the network device on the N channels with respect to the first information.

Therefore, the beneficial effects that can be achieved can refer to the beneficial effects of the corresponding methods and will not be repeated here.

[0095] The embodiments of the present disclosure are now further described with reference to the accompanying drawings and specific implementation methods.

[0096] 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. The embodiments described in the following exemplary embodiments are not intended to represent all possible implementations consistent with the present disclosure. Rather, they are merely examples of devices and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0097] The terms used in the embodiments of the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the embodiments of the present disclosure. The singular forms "a," "an," and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise. 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.

[0098] 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".

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] The capabilities of the first type of terminal include: no energy storage capability, and no independent signal generation or amplification.

[0107] In one example, the first terminal uses a backscattering working mode.

[0108] The capabilities of the second type of terminal include: energy storage capability, and inability to generate independent signals.

[0109] In one example, the second terminal may use a backscattering working mode, and may also use the stored energy to amplify the reflected signal.

[0110] The capabilities of the third type of terminal include: energy storage capability and the ability to independently generate signals.

[0111] In one example, the third type of terminal has a radio frequency (RF) module that actively sends signals.

[0112] 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.

[0113] 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."

[0114] 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.

[0115] In the disclosed embodiment, in large-scale cargo inventory (e.g., used 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.

[0116] In the disclosed embodiments, in scenarios involving mass cargo identification, when Ambient-IoT communicates with network devices, the network devices, upon receiving information from Ambient-IoT, must send feedback to Ambient-IoT confirming successful receipt of the information. Because the device ID of the Ambient-IoT sending information to the network device contains a large number of bits—for example, in the EPC standard, each EPC-encoded Ambient-IoT can have 256 bits—the signaling overhead associated with sending feedback based on the terminal ID is significant, necessitating consideration of how to reduce the feedback signaling overhead.

[0117] FIG2A is an interactive schematic diagram of a communication method provided according to an embodiment of the present disclosure. As shown in FIG2A , the method includes the following steps:

[0118] Step S2101: Terminal 101 and network device 102 send first information.

[0119] In some possible embodiments, the terminal 101 sends the first information to the network device 102 through N channels.

[0120] In some possible embodiments, the network device 102 receives the first information through N channels.

[0121] In some possible embodiments, the N channels are one or more of the M channels, and both N and M are integers greater than 0.

[0122] In some possible embodiments, the M channels include at least one of the following: a time domain channel, a frequency domain channel, and a code domain channel.

[0123] In some possible embodiments, M channels correspond to one resource pool.

[0124] In some possible embodiments, the type of channels included in the resource pool includes at least one of the following: a time domain channel, a frequency domain channel, and a code domain channel.

[0125] In some possible embodiments, the terminal 101 sends the first information on each of the N channels.

[0126] In some possible embodiments, the terminal 101 sends the first information jointly through the N channels, and sends different parts of the first information on different channels among the N channels.

[0127] Step S2102: the network device 102 sends the second information.

[0128] In some possible embodiments, the second information is used to indicate feedback information of the network device 102 on the N channels with respect to the first information.

[0129] In some possible embodiments, the second information includes M pieces of feedback information, wherein each piece of feedback information corresponds to one of the M channels.

[0130] In one example, when the resource pool includes 100 channels, the second information includes 100 pieces of feedback information, and each piece of feedback information occupies 1 bit.

[0131] The value of this bit is 1, indicating that the information sent on this channel has been successfully received by the network device 102, i.e., it indicates Acknowledgement (ACK);

[0132] The value of this bit is 0, indicating that the information sent on this channel is not successfully received by the network device 102, that is, it indicates negative acknowledgment (ACK).

[0133] In some possible embodiments, no information is transmitted on at least one of the M channels, and the second information also includes feedback information corresponding to each channel in the at least one channel.

[0134] In one example, the feedback information corresponding to each channel without information transmission is a set value.

[0135] In one example, the setting value is NACK.

[0136] Step S2103: Terminal 101 determines feedback information.

[0137] In some possible embodiments, the terminal 101 determines, based on the N channels, the feedback information of the network device 102 for the first information on the N channels from M pieces of feedback information in the second information.

[0138] In one example, the terminal 101 determines the feedback information of the network device 102 on each of the N channels from the M feedback information in the second information according to the N channels.

[0139] In some possible embodiments, when the terminal 101 sends the first information on each of the N channels, when the second information indicates that the feedback information corresponding to any one of the N channels by the network device 102 is successfully received, it is determined that the network device 102 successfully receives the first information.

[0140] In one example, M is 100, N is 4, the terminal 101 sends the first information on all four channels, and when the second information indicates that the feedback information corresponding to any one of the four channels is ACK, it is determined that the network device 102 successfully receives the first information.

[0141] In some possible embodiments, when the first information is sent jointly through the N channels and different parts of the first information are sent on different channels among the N channels, when the second information indicates that the feedback information corresponding to any one of the N channels of the network device 102 is not successfully received, it is determined that the network device 102 has not successfully received the first information.

[0142] In one example, M is 100, N is 4, the terminal 101 sends the first part of the first information on the first two channels of the four channels, and sends the second part of the first information on the last two channels of the four channels. When the second information indicates that the feedback information corresponding to any one of the four channels is NACK, it is determined that the network device 102 has not successfully received the first information.

[0143] The communication method involved in the embodiment of the present disclosure may include at least one of steps S2101 to S2103. For example, step S2102 and step S2103 may be implemented as independent embodiments, but are not limited thereto.

[0144] FIG2B is an interactive schematic diagram of a communication method provided according to an embodiment of the present disclosure. As shown in FIG2B , the method includes the following steps:

[0145] Step S2201: Terminal 101 sends first information to network device 102.

[0146] The optional implementation of step S2201 can refer to the optional implementation of step S2101 in Figure 2A and other related parts in the embodiment involved in Figure 2A, which will not be repeated here.

[0147] In step S2202 , the network device 102 performs a logical AND operation.

[0148] In some possible embodiments, the M channels include one or more groups, wherein each group includes K channels of the M channels, where K is an integer greater than 1 and less than or equal to N.

[0149] In some possible embodiments, the K channels in each group are determined by the network device 102 itself and are independent of the terminal 101 .

[0150] In one example, the value of M is 100, the value of K is 4, and the second information includes 25 (ie, 100 / 4) groups, each group includes 4 channels, and each group corresponds to the logical AND operation result of the feedback information of the 4 channels.

[0151] In one example, the feedback information of the four channels corresponding to a group is ACK, ACK, ACK, and NACK in sequence, and the logical AND operation result of the feedback information of the four channels is the logical AND operation result of ACK, ACK, ACK, and NACK, that is, NACK.

[0152] In some possible embodiments, the N channels used by the terminal 101 network device 102 to send the first information are part of the K channels in a group, or the N channels used by the terminal 101 network device 102 to send the first information include all channels in at least one group.

[0153] In some possible embodiments, the network device 102 performs a logical AND operation on the feedback information of the K channels in each packet, and uses the result of the logical AND operation as the first feedback information of the packet.

[0277] Step S6101: Send first information to the network device 102 via a first resource.

[0278] In some possible embodiments, the first resource is part of a resource pool, and the resource pool includes multiple channels.

[0279] In some possible embodiments, the type of channels included in the resource pool includes at least one of the following: a time domain channel, a frequency domain channel, and a code domain channel.

[0280] Step S6102: Receive second information for feedback sent by the network device 102.

[0281] In one example, there are a total of 100 channels in the resource pool, the feedback information has 100 bits, and each bit corresponds to the feedback information of one channel.

[0282] In some possible embodiments, the bit corresponding to a channel is 0, indicating that the information sent on this channel is not correctly received by the network device 102, that is, NACK; the bit corresponding to a channel is 1, indicating that the information sent on this channel is correctly received by the network device 102, that is, ACK.

[0288] In one example, there are a total of 100 channels in the resource pool. Every 4 channels are combined into a group to perform a logical AND operation to obtain 1 bit of feedback information. The total amount of feedback information is 25 bits.

[0289] In some possible embodiments, each logical AND operation result is a NACK feedback result, and the feedback result of each channel corresponding to the feedback result is determined.

[0290] In one example, there are 100 channels in the resource pool. Four channels are grouped together and logically ANDed to obtain 1 bit of feedback information, resulting in a total of 25 bits of feedback information. For each of the four channels where the logical ANDed result is a NACK, 4 bits are used to indicate the ACK / NACK information for each of these four channels.

[0291] In some possible embodiments, the feedback information includes two parts. The first part is the result of a logic AND operation; the second part is the number of bits corresponding to multiple channels for which the result of the logic AND operation is NACK.

[0292] In one example, the first part has X logical AND operations whose results are NACK, each logical AND operation corresponds to n channels, and the second part has n×X bits.

[0293] In some possible embodiments, the first part and the second part are encoded independently.

[0294] The number of bits in the second part is not fixed and is determined based on the information in the first part.

[0295] In some possible embodiments, the terminal 101 first completes decoding of the first part, and then uses the feedback information of the first part to decode the second part.
