[0038] The embodiments of the present disclosure provide a channel configuration method and apparatus, a communication device, a communication system, and a storage medium.

[0039] In a first aspect, an embodiment of the present disclosure provides a channel configuration method, which is performed by a network device. The method includes:

[0040] Configure at least one first channel; the first channel is a channel used by the network device to send downlink information to the first device, and the first device is: a passive Internet of Things A-IoT device.

[0041] In the above embodiment, a method for configuring a first channel is provided, wherein the first channel is a channel used by a network device to transmit downlink signals to a first device, and the first device is an A-IoT device. Therefore, it can be seen that the present disclosure specifically provides a method for configuring a "downlink channel from a network device to an A-IoT device," thereby enabling downlink signals between the network device and the A-IoT device, thereby ensuring communication stability and performance of the first device (i.e., the A-IoT device).

[0042] In conjunction with some embodiments of the first aspect, in some embodiments, the downlink transmission performed by the network device to the first device includes at least one of the following:

[0043] Downlink transmission performed directly by the network device to the first device;

[0044] The network device sends downlink data to the first device through the intermediate node.

[0045] In the above embodiment, the specific scenarios of downlink transmission between the network device and the first device are defined so that the method of the present disclosure can be used to configure the downlink channel in the corresponding scenario, so that downlink transmission can be successfully achieved between the network device and the first device in the corresponding scenario, thereby ensuring the communication stability and communication performance of the first device (i.e., A-IoT device).

[0046] In combination with some embodiments of the first aspect, in some embodiments, the downlink sending includes: the network device sending at least one type of downlink information to the first device.

[0047] With reference to some embodiments of the first aspect, in some embodiments, the at least one type of downlink information includes one or more of the following:

[0048] Control information;

[0049] Data information;

[0050] System broadcast information;

[0051] Signaling message.

[0052] In the above embodiment, it is defined which downlink information is specifically sent in the downlink transmission between the network device and the first device, so that the method of the present disclosure can be used to configure a downlink channel for sending the downlink information, so that the corresponding downlink information can be successfully sent between the network device and the first device, thereby ensuring the communication stability and communication performance of the first device (i.e., A-IoT device).

[0053] In conjunction with some embodiments of the first aspect, in some embodiments, configuring at least one first channel includes:

[0054] A first channel is configured, where the first channel is used to send multiple types of downlink information.

[0055] In conjunction with some embodiments of the first aspect, in some embodiments, configuring at least one first channel includes:

[0056] Multiple first channels are configured, each of which is used to send one or more types of downlink information.

[0057] In conjunction with some embodiments of the first aspect, in some embodiments, configuring multiple first channels includes:

[0058] Three first channels are configured, wherein the first first channel is used to send control information and / or signaling messages, the second first channel is used to send data information, and the third first channel is used to send system broadcast information and / or signaling messages.

[0059] In conjunction with some embodiments of the first aspect, in some embodiments, configuring multiple first channels includes:

[0060] Two first channels are configured, wherein a first first channel is used to send control information and / or signaling messages, and a second first channel is used to send data information.

[0061] In combination with some embodiments of the first aspect, in some embodiments, the first first channel is also used to send first information before sending the control information and / or signaling message, and / or the second first channel is also used to send first information before sending the data information; the first information is used to achieve downlink synchronization.

[0062] In conjunction with some embodiments of the first aspect, in some embodiments, configuring multiple first channels includes:

[0063] Two first channels are configured, wherein the first first channel is used to send system broadcast information and / or signaling messages, and the second first channel is used to send at least one of control information, data information, and signaling messages.

[0064] In the above embodiment, a method for configuring a downlink channel between a network device and a first device is provided, so as to successfully configure at least one downlink channel between the network device and the first device, so that the network device can successfully use the configured downlink channel to send downlink information to the first device, thereby ensuring the communication stability and communication performance of the first device (i.e., A-IoT device). In addition, in the above embodiment, since the first device has the characteristic of transmitting a small amount of data, the total amount of data of the various types of downlink information sent to the first device will also be small. On this basis, a first channel can be configured between the network device and the first device, and the first channel can be used to send various types of downlink information without configuring multiple downlink channels. Therefore, on the basis of ensuring the successful transmission of various types of downlink information, channel resources can be saved, communication costs can be reduced, and the complexity of implementation can be reduced.

[0065] In conjunction with some embodiments of the first aspect, in some embodiments, when the same first channel sends multiple types of downlink information, there is at least one of the following differences between the different types of downlink information:

[0075] In the above embodiment, when multiple types of downlink information are sent using the same first channel, different methods can be used to process the multiple types of downlink information, thereby allowing the first device to distinguish which type of downlink information is specifically sent by the network device, thereby ensuring the accuracy of the downlink transmission. In addition, in the above embodiment, since the processing capability and power consumption of the first device are both low, different types of downlink information can occupy at least one of the time domain resources, frequency domain resources, time domain resource length, and frequency domain resource length, to ensure that different types of downlink information are sent at different locations, thereby avoiding the first device from receiving different types of downlink information at the same time, reducing the complexity of the first device. At the same time, the downlink transmission is adapted to the low processing capability and low power consumption of the first device, ensuring that the downlink transmission can be successfully received by the low processing capability and low power consumption first device, thereby ensuring the communication stability of the first device. In addition, in the above embodiment, considering the high coverage of the first device, each type of downlink information can be made to occupy a continuous integer number of time domain resource units and / or a continuous integer number of frequency domain resource units, thereby improving the coverage of the downlink transmission, so that the downlink transmission can be adapted to the high coverage of the first device, and improving the performance of the downlink transmission.

Moreover, even when a large number of first devices are connected to the network device, no interference will occur between different channels of different first devices, thereby ensuring communication performance. In addition, in the above embodiment, taking into account the high coverage of the first device, each first channel can occupy a continuous integer number of time domain resource units and / or a continuous integer number of frequency domain resource units, so as to improve the coverage of downlink transmission, so that the downlink transmission can adapt to the high coverage of the first device, thereby improving the performance of downlink transmission.

As shown in Figure 1A, the communication system 100 may include a first device and a network device. Optionally, the first device may be an A-IoT device, such as a terminal. The network device may include at least one of an access network device and a core network device.

[0246] In some embodiments, the terminal includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0249] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0250] In some embodiments, the core network device may be a device including one or more network elements, or may be multiple devices or a group of devices, each including all or part of one or more network elements. The network element may be virtual or physical. The core network, for example, includes at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC). Alternatively, the core network device may also be a location management function network element.

[0251] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0252] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1A , or a portion thereof, but are not limited thereto. The entities shown in FIG1A are illustrative only. The communication system may include all or part of the entities shown in FIG1A , or may include other entities other than those shown in FIG1A . The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only.

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0254] Optionally, the aforementioned A-IoT device may also be referred to as, for example, an A-IoT UE, an A-IoT terminal, an A-IoT Tag, etc., and the A-IoT device may not require configuration or replacement of batteries, nor may it generate its own energy. Instead, it may collect energy from the outside world, such as based on signals sent by the surrounding environment or peripheral devices, and may communicate based on the collected energy. Optionally, the A-IoT device may be used in scenarios involving inventorying large quantities of items. For example, the A-IoT device may report an Electronic Product Code (EPC) code to a network device, an intermediate node, or a terminal. Alternatively, the A-IoT device may be used in sensing scenarios such as smart homes and environmental monitoring. For example, when certain trigger conditions are met, the A-IoT device may report data. Alternatively, the A-IoT device may be used in positioning scenarios to find items or locate items within a shopping mall. Alternatively, the A-IoT device may be used in command scenarios to respond to commands sent by a network device.

[0255] Optionally, in some embodiments, the A-IoT device may send signaling and / or data based on backscatter. Among them, for A-IoT devices based on backscatter, there is usually a need for an energy source (continuous wave node, CW node) that provides continuous electromagnetic waves (continuous wave, CW) to provide the A-IoT device with CW for reflection. In addition, the A-IoT device can receive the CW sent by the energy source, and the CW can also be used to charge the A-IoT device to activate the internal receiving and processing module to start working, so that the A-IoT device can encode and modulate the signaling and / or data to be sent, and load the signaling and / or data to be sent onto the reflected wave and send it out, thereby realizing backscatter communication.

[0256] Optionally, the energy source may be a separate node, or a base station communicating with the A-IoT device, or an intermediate node (such as a terminal) communicating with the A-IoT device. Optionally, the frequency of the electromagnetic waves emitted by the energy source may be a constant amplitude, and the transmission frequency used by the A-IoT device when reflecting the electromagnetic waves may be the same as the frequency of the electromagnetic waves emitted by the energy source, or the transmission frequency used by the A-IoT device when reflecting the electromagnetic waves may be offset from the frequency of the electromagnetic waves emitted by the energy source, wherein the magnitude of the offset value is related to the hardware characteristics of the A-IoT device. Optionally, the offset value may be a fixed value, or the offset value may be dynamically adjusted.

[0257] Optionally, the above-mentioned A-IoT devices may be of different types, for example, including A-IoT device A (Device A), A-IoT device B (Device B), and A-IoT device C (Device C). Different types of A-IoT devices have different corresponding capabilities.

[0258] Optionally, the A-IoT device A cannot independently generate or amplify signals, but instead uses a backscattering mode to send signaling and / or data. This reduces the supported coverage area while minimizing complexity and cost, and consuming very little power. Furthermore, the modulation and demodulation methods used by the A-IoT device A are relatively simple, such as On-Off Keying (OOK) and Phase-Shift Keying (PSK).

[0259] Optionally, the A-IoT device B has energy storage capabilities but cannot independently generate signals. Instead, it can communicate using backscattering and use the stored energy to amplify uplink and / or downlink signals. Furthermore, the modulation and demodulation methods used by the A-IoT device B are relatively simple, such as OOK or PSK.

[0260] Optionally, the above-mentioned A-IoT device C has energy storage capabilities and can independently generate and send signals. For example, the A-IoT device C can have a wireless radio frequency (RF) module that actively sends signals. In addition, the A-IoT device C can use the stored energy to independently generate and send signals, and amplify the uplink signal and / or downlink signal. Optionally, the A-IoT device C can use a more complex modulation and demodulation method, such as orthogonal frequency division multiplexing (OFDM) and other modulation and demodulation methods. The complexity and cost of the A-IoT device C are both high and the power consumption is large.

[0261] Optionally, in a passive IoT system, the data transmission of an A-IoT device may be of the following three types:

[0262] Example 1: An A-IoT device reports data based on demand from network devices, such as inventory counts.

[0263] Example 2: Triggering an A-IoT device to report based on environmental IoT. For example, when the A-IoT device detects that the temperature of a sensor is higher than the configured threshold, the A-IoT device reports the relevant data.

[0264] Example 3: Periodic data reporting. For example, the network can periodically request data from A-IoT devices to implement periodic environmental IoT data reporting; or the network can trigger the A-IoT devices themselves to implement periodic environmental IoT data reporting.

[0265] Optionally, the above-mentioned A-IoT device can be applicable to a variety of different communication architectures in the communication system, wherein Figures 1B and 1C are schematic diagrams of the communication architecture of the A-IoT device according to the embodiment of the present disclosure. Optionally, as shown in Figure 1B, data can be directly received and sent between the A-IoT device (i.e., the Ambient IoT device in Figure 1B) and the network device (such as a base station (BS)). And, as shown in Figure 1C, data can be indirectly received and sent between the A-IoT device and the network device (such as a base station (BS)) through an intermediate node, wherein the intermediate node can be, for example, a relay, an integrated access backhaul (IAB) device, a terminal, or a repeater.

[0266] However, there is currently no clear configuration method for the downlink channel between "network devices and A-IOT devices". Since A-IOT devices have characteristics such as small memory, low processing power, low power consumption, small amount of transmitted data, high coverage, and support for a large number of A-IOT device connections, the design of the downlink channel in the A-IOT scenario needs to integrate these characteristics to streamline the design of some channels, thereby reducing the complexity of implementation and product complexity.

[0267] FIG2A is an interactive diagram of a channel configuration method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a channel configuration method for a communication system 100, the method comprising:

[0268] Step 2101: The network device configures a first channel.

[0269] Optionally, the first channel may be a channel used by the network device to transmit downlink information to the first device. That is, the first channel may be understood as a downlink channel from the network device to the first device. The first device may, for example, be an A-IoT device. For a detailed description of the A-IoT device, please refer to the description of the embodiment shown in FIG. 2A .

[0270] Optionally, the downlink transmission performed by the network device to the first device may include at least one of the following:

[0271] Downlink transmission performed directly from the network device to the first device; for example, downlink transmission is performed directly between the network device and the A-IoT device as shown in FIG1B ; in this case, the first channel may refer to a downlink channel between the network device and the first device;

[0272] The network device sends downlink information to the first device through the intermediate node; for example, the network device and the A-IoT device shown in Figure 1C send downlink information indirectly through the intermediate node; in this case, the first channel may include: a downlink channel between the network device and the intermediate node, and / or a downlink channel between the intermediate node and the first device.

[0273] Optionally, in some embodiments, the downlink transmission may specifically include: the network device sending at least one type of downlink information to the first device. Optionally, the at least one type of downlink information may include one or more of the following:

[0274] Control information;

[0275] Data information;

[0276] System broadcast information;

[0277] Signaling message.

[0278] Among them, the above-mentioned "control information" may include, for example, uplink scheduling information and / or downlink scheduling information, wherein the uplink scheduling information may be used to schedule uplink resources between the network device and the first device, and the uplink resources may, for example, be: the resources used when the first device sends uplink to the network device; the downlink scheduling information may be used to schedule downlink resources between the network device and the first device, and the downlink resources may, for example, be: the resources used when the network device sends downlink to the first device.

[0279] Optionally, the aforementioned "data information" may be, for example, a command sent by the network device to the first device that requires a response from the first device. The command may include, for example, an inventory command that requires a response from the first device and / or an access command that requires a response from the first device. The inventory command may include, for example, Query, QueryAdjust, QueryRep, ACK, NAK, etc. The access command may include, for example, Req_RN, Read, Write, Kill, Lock, etc.

[0280] Optionally, the above-mentioned "system broadcast information" can be, for example, information used to achieve downlink synchronization of the first device. For example, the "system broadcast information" can be: synchronization signal block (Synchronization Signal Block, SSB), primary synchronization signal (primary synchronization signal, PSS), secondary synchronization signal (secondary synchronization signal, SSS), etc.

[0281] Optionally, the above-mentioned “signaling message” may also be, for example, the above-mentioned control information or system broadcast information. For example, downlink control information (DCI) signaling belongs to both “signaling message” and “control information”.

[0282] In some embodiments, when a network device is configured with a first channel, the first channel can be used to send multiple types of downlink information. For example, the first channel can be used to send all types of downlink information mentioned above, that is, the first channel can be used to send the above-mentioned control information, data information, system broadcast information, signaling messages, etc.

[0283] Optionally, in the above embodiment, since the first device has the characteristic of transmitting a small amount of data, the total data amount of multiple types of downlink information sent to the first device will also be small. On this basis, by configuring a first channel between the network device and the first device, and using the one first channel to send multiple types of downlink information without configuring multiple downlink channels, it is possible to save channel resources, reduce communication costs, and reduce the complexity of implementation while ensuring the successful transmission of multiple types of downlink information.

[0284] Furthermore, in some embodiments, the network device may configure the aforementioned first channel for the first device, and the first device may determine the first channel based on the configuration of the network device.

[0285] Step 2102: The network device uses the first channel to send multiple types of downlink information.

[0286] Optionally, the network device may use the one first channel to send multiple types of downlink information to the first device, and the first device may receive the multiple types of downlink information sent by the network device on the one first channel. For example, the first device may receive control information, data information, system broadcast information, signaling messages, etc. sent by the network device on the one first channel.

[0287] In some embodiments, when multiple types of downlink information are transmitted on the same first channel, the different types of downlink information may differ from each other by at least one of the following:

[0288] The sending format is different;

[0289] The scrambled Radio Network Temporary Identifier (RNTI) is different;

[0290] Different modulation and coding methods;

[0291] The cyclic redundancy check (CRC) length is different;

[0292] The time domain resources occupied are different;

[0293] The occupied frequency domain resources are different

[0294] The length of the time domain resources occupied is different;

[0295] The lengths of the occupied frequency domain resources are different.

[0296] Optionally, if the sending formats of different types of downlink information are different, in some instances, the sending format of the control information may be: downlink channel format 1 (APDSCH format 1); the sending format of the system broadcast information may be: downlink channel format 2 (APDSCH format 2); the sending format of the data information may be: downlink channel format 3 (APDSCH format 3); and the sending format of the signaling message may be: downlink channel format 4 (APDSCH format 4).

[0297] Optionally, if the scrambled RNTIs between different types of downlink information are different, in some instances, the scrambled RNTI of the control information may be: Cell Radio Network Temporary Identifier (C-RNTI); the scrambled RNTI of the system broadcast information may be: System Information-radio network temporary identifier (SI-RNTI); the scrambled RNTI of the data information may be: Modulation Coding Scheme Cell Radio Network Temporary Identifier (MCS-C-RNTI); the scrambled RNTI of the signaling message may be: Temporary Radio Network Temporary Identifier (T-RNTI).

[0298] Optionally, if the modulation and coding methods of different types of downlink information are different, in some instances, the modulation and coding method of the control information may be: PSK modulation and coding method; the modulation and coding method of the system broadcast information may be: PSK modulation and coding method; the modulation and coding method of the data information may be: Amplitude Shift Keying (ASK) modulation and coding method; and the modulation and coding method of the signaling message may be: ASK modulation and coding method.

[0299] Optionally, if the CRC lengths of different types of downlink information are different, in some instances, the CRC length of the control information can be: 16; the CRC length of the system broadcast information can be: 16; the CRC length of the data information can be: 24; and the CRC length of the signaling message can be: 24.

[0300] Optionally, in some embodiments, the above-mentioned time domain resources may include, for example, at least one of symbols, time slots, subframes, milliseconds, seconds, etc., and the above-mentioned frequency domain resources may include, for example, at least one of subcarriers, resource blocks (RB), bandwidth, etc.

[0301] And, optionally, if the lengths of the time domain resources occupied and the lengths of the frequency domain resources occupied by different types of downlink information are different, then in some instances, the frequency domain resources occupied and the time domain resources occupied by the control information can be: 1 subcarrier and 2 time slots, respectively; the frequency domain resources occupied and the time domain resources occupied by the system broadcast information can be: 6 subcarriers and 1 time slot, respectively; the frequency domain resources occupied and the time domain resources occupied by the data information can be: 12 subcarriers and 4 time slots, respectively; the frequency domain resources occupied and the time domain resources occupied by the signaling message can be: 12 subcarriers and 4 time slots, respectively.

[0302] Furthermore, in some embodiments, each type of downlink information may occupy a continuous integer number of time domain resource units, and / or each type of downlink information may occupy a continuous integer number of frequency domain resource units. Optionally, the time domain resource unit may include, for example, at least one of a symbol, a time slot, a subframe, a millisecond, a second, etc., and the frequency domain resource unit may include, for example, at least one of a subcarrier, an RB, a bandwidth, etc. For example, in some embodiments, each type of downlink information occupies a continuous integer number of time domain resource units, which may be reflected as follows: control information occupies N continuous time slots; system broadcast information occupies M continuous time slots; data information occupies X continuous time slots; signaling messages occupy Y continuous time slots. Wherein, N, M, X, and N are different positive integers.

[0303] As can be seen from the above, when multiple types of downlink information are sent using the same first channel, different methods can be used to process the multiple types of downlink information, thereby allowing the first device to distinguish which type of downlink information is specifically sent by the network device, thereby ensuring the accuracy of the downlink transmission. In addition, in the above embodiment, since the processing capability and power consumption of the first device are both low, different types of downlink information can occupy at least one of the time domain resources, frequency domain resources, time domain resource length, and frequency domain resource length, to ensure that different types of downlink information are sent at different locations, thereby avoiding the first device from receiving different types of downlink information at the same time, reducing the complexity of the first device. At the same time, the downlink transmission is adapted to the low processing capability and low power consumption of the first device, ensuring that the downlink transmission can be successfully received by the low processing capability and low power consumption first device, thereby ensuring the communication stability of the first device. In addition, in the above embodiment, considering the high coverage of the first device, each type of downlink information can be made to occupy a continuous integer number of time domain resource units and / or a continuous integer number of frequency domain resource units, thereby improving the coverage of the downlink transmission, so that the downlink transmission can be adapted to the high coverage of the first device, and improving the performance of the downlink transmission.

[0304] In the above embodiment, a method for configuring a first channel is provided, wherein the first channel is a channel used by a network device to transmit downlink signals to a first device, and the first device is an A-IoT device. Therefore, it can be seen that the present disclosure specifically provides a method for configuring a "downlink channel from a network device to an A-IoT device," thereby enabling downlink signals between the network device and the A-IoT device, thereby ensuring communication stability and performance of the first device (i.e., the A-IoT device).

[0305] The channel configuration method involved in the embodiments of the present disclosure may include at least one of steps 2101 and 2102. For example, step 2101 may be implemented as an independent embodiment, step 2102 may be implemented as an independent embodiment, step 2103 may be implemented as an independent embodiment, and step 2101+step 2102 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0306] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0307] FIG2B is an interactive diagram of a channel configuration method according to an embodiment of the present disclosure. As shown in FIG2B , the embodiment of the present disclosure relates to a channel configuration method for a communication system 100, the method comprising:

[0308] Step 2201: The network device configures multiple first channels.

[0309] For a detailed introduction to the first channel, please refer to the above embodiment description.

[0310] Furthermore, when the network device is configured with multiple first channels, each first channel can be used to send one or more types of downlink information.

[0311] Optionally, in some embodiments, the network device may be configured with three first channels, wherein the first first channel may be used to send control information and / or signaling messages, the second first channel may be used to send data information, and the third first channel may be used to send system broadcast information and / or signaling messages.

[0312] In some other embodiments, the network device may be configured with two first channels, wherein the first first channel may be used to send control information and / or signaling messages, and the second first channel may be used to send data information. Wherein, when the network device is configured with the aforementioned two first channels, there is no channel for sending system broadcast information, which will cause the loss of system broadcast information. Since the system broadcast information is used to achieve downlink synchronization, if the system broadcast information is missing, it may make the first device unable to achieve downlink synchronization. Based on this, in some embodiments, the first first channel may also be used to send the first information before sending the control information and / or signaling message, and / or, the second first channel may also be used to send the first information before sending the data information. Wherein, the first information can be used to achieve downlink synchronization, thereby compensating for the defect that "the first device cannot achieve downlink synchronization due to the lack of system broadcast information". Optionally, the first information may be, for example, a preamble and / or a frame synchronization (frame-sync). For example, the preamble may be a high-low pulse with a duration of t1, and the frame-sync may be a high-low pulse with a duration of t2, where t1 is not equal to t2; or, the preamble may be an OFDM symbol with a duration of t1, and the frame-sync may be an OFDM symbol with a duration of t2, where t1 is not equal to t2.

[0313] In some further embodiments, the network device may be configured with two first channels, wherein the first first channel may be used to send system broadcast information and / or signaling messages, and the second first channel may be used to send at least one of control information, data information, and signaling messages.

[0314] It should be noted that, in some embodiments, the above-mentioned first channel for sending control information and / or signaling messages can be called, for example, a downlink control channel; the above-mentioned first channel for sending data information can be called, for example, a downlink data channel; the above-mentioned first channel for sending system broadcast information and / or signaling messages can be called, for example, a downlink broadcast channel.

[0315] Optionally, in some embodiments, different first channels may have at least one of the following differences:

[0316] The time domain resources occupied are different;

[0317] The occupied frequency domain resources are different

[0318] The length of the time domain resources occupied is different;

[0319] The lengths of the occupied frequency domain resources are different.

[0320] For detailed introduction of time domain resources, frequency domain resources, time domain resource length, and frequency domain resource length, please refer to the description of the above embodiments.

[0321] And, for example, the different time domain resources occupied by different first channels can be reflected as follows: the time domain resources of the downlink control channel and the downlink data channel are located in different time slots or subframes, and the time domain resources of the downlink control channel and the downlink broadcast channel are located in different time slots or subframes.

[0322] Furthermore, in some embodiments, each first channel may occupy a consecutive integer number of time domain resource units, and / or each first channel may occupy a consecutive integer number of frequency domain resource units. For detailed descriptions of occupying consecutive integer number of time domain resource units and occupying consecutive integer number of frequency domain resource units, please refer to the above embodiments.

[0323] Based on the above content, taking into account the characteristics of the network device supporting a large number of first device connections, it is possible to make the time domain resources, frequency domain resources, time domain resource length, and frequency domain resource length occupied by different first channels of the network device and different first devices different, thereby avoiding position duplication between the first channels corresponding to different first devices, avoiding interference between different first channels, and even when a large number of first devices are connected to the network device, no interference will occur between different channels of different first devices, thereby ensuring communication performance. In addition, in the above embodiment, taking into account the high coverage of the first device, each first channel can occupy a continuous integer number of time domain resource units and / or a continuous integer number of frequency domain resource units, so as to improve the coverage of downlink transmission, so that the downlink transmission can adapt to the high coverage of the first device, and improve the performance of downlink transmission.

[0324] In addition, for other introductions to step 2201, please refer to the description of the above embodiment.

[0325] Step 2202: The network device uses the multiple first channels to send multiple types of downlink information.

[0326] Optionally, the network device may use the multiple first channels to send multiple types of downlink information to the first device, and the first device may receive the multiple types of downlink information.

[0327] In some embodiments, when the network device is configured with three first channels, the network device can send control information and / or signaling messages on the first first channel, send data information on the second first channel, and send system broadcast information and / or signaling messages on the third first channel; and the first device can perform at least one of the following: receiving control information and / or signaling messages sent by the network device on the first first channel, receiving data information sent by the network device on the second first channel, and receiving system broadcast information and / or signaling messages sent by the network device on the third first channel.

[0328] In some other embodiments, when the network device is configured with two first channels, the network device can send control information and / or signaling messages on the first first channel and send data information on the second first channel; and the first device can perform at least one of the following: receive control information and / or signaling messages sent by the network device on the first first channel; receive data information sent by the network device on the second first channel. Further, in some embodiments, before the network device sends control information and / or signaling messages on the first first channel, it can also send first information on the first first channel, and / or, before sending data information on the second first channel, it can also send first information on the second first channel. In addition, the first device can also receive the first information sent by the network device before the control information and / or signaling messages on the first first channel; and / or, receive the first information sent by the network device before the data information on the second first channel. For other introductions to the first information, please refer to the description of the above embodiments.

[0329] In some further embodiments, when the network device is configured with two first channels, the network device can send system broadcast information and / or signaling messages on the first first channel, and send at least one of control information, data information, and signaling messages on the second first channel; and the first device can perform at least one of the following: receive system broadcast information and / or signaling messages sent by the network device on the first first channel; receive at least one of control information, data information, and signaling messages sent by the network device on the second first channel.

[0330] When the network device sends multiple types of downlink information on the same first channel, or when the first device receives multiple types of downlink information on the same first channel, the different types of downlink information may differ from each other, and each type of downlink information may occupy a consecutive integer number of time domain resource units and / or each type of downlink information may occupy a consecutive integer number of frequency domain resource units. For a detailed description of this part, please refer to the above embodiment description.

[0331] In the above embodiment, a method for configuring a first channel is provided, wherein the first channel is a channel used by a network device to transmit downlink signals to a first device, and the first device is an A-IoT device. Therefore, it can be seen that the present disclosure specifically provides a method for configuring a "downlink channel from a network device to an A-IoT device," thereby enabling downlink signals between the network device and the A-IoT device, thereby ensuring communication stability and performance of the first device (i.e., the A-IoT device).

[0442] Figure 5 is an interactive diagram of a channel configuration method according to an embodiment of the present disclosure. As shown in Figure 5, the embodiment of the present disclosure relates to a channel configuration method for a communication system including a first device and a network device. The method includes at least one of the following:

[0443] Step 5101: The network device configures at least one first channel;

[0444] Step 5102: The network device sends downlink information on at least one first channel.

[0445] Step 5103: The first device receives downlink information sent by the network device on at least one first channel.

[0446] Optional implementations of steps 5101 to 5103 may refer to the description of the above embodiment.

[0447] In some embodiments, the above method may include the method described in the above embodiments of the communication system side, the first device side, the network device side, etc., which will not be repeated here.

[0448] The channel configuration method involved in the embodiment of the present disclosure may include at least one of steps 5101 to 5103. For example, step 5101 may be implemented as an independent embodiment, and step 5102 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0449] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0450] The following is an exemplary introduction to the above method.

[0451] The present disclosure proposes a streamlined design of a downlink channel in an A-IOT scenario, which can reduce the complexity of implementation and product complexity.

[0452] Optional example 1: Only one downlink channel is defined, and control information, data information, system broadcast information, signaling messages, etc. can be transmitted on this downlink channel, and different downlink channel formats are used to send different information.

[0453] Embodiment 1: The downlink channel may have multiple transmission formats. For example, downlink channel format 1 (APDSCH format 1) is used to transmit control information, which can be divided into uplink scheduling information or downlink scheduling information. Format 2 (APDSCH format 2) is used to transmit system broadcast information. Format 3 (APDSCH format 3) is used to transmit data. Format 4 (APDSCH format 4) is used to transmit signaling messages.

[0454] 1. The data sent can be commands that require AIOT devices to respond, such as inventory commands: Query, QueryAdjust, QueryRep, ACK, NAK, access commands, such as Req_RN, Read, Write, Kill, Lock

[0455] 2. Exemplarily, different downlink channel formats use different RNTIs for scrambling. Exemplarily, downlink channel format 1 uses C-RNTI for scrambling, downlink channel format 2 uses SI-RNTI for scrambling, format 3 uses MCS-C-RNTI for scrambling, and format 4 uses T-RNTI for scrambling.

[0456] 3. For example, different downlink channel formats use different modulation and coding methods. For example, downlink channel format 1 (APDSCH format 1) is used to send control information and can use PSK modulation. Downlink channel format 3 (APDSCH format 3) is used to send data and can use ASK modulation. Format 2 (APDSCH format 2) is used to send system broadcast information and can use PSK modulation, etc.

[0457] 4. For example, different downlink channel formats may use different CRC lengths. For example, formats 1 and 2 use a CRC length of 16, while format 3 downlink channels use a CRC length of 24.

[0458] 3. Exemplarily, different downlink channel formats occupy different amounts of time domain resources (symbols, time slots, subframes, milliseconds, seconds, etc.) and frequency domain resources (such as subcarriers, RBs, bandwidth, etc.). Exemplarily, downlink channel format 1 occupies 1 subcarrier and 2 time slots, downlink channel format 2 occupies 6 subcarriers and 1 time slot, and downlink channel format 3 occupies 12 subcarriers and 4 time slots.

[0459] 4. Exemplarily, each downlink channel format occupies a continuous integer number of time domain resource units in the time domain. For example, downlink channel format 1 occupies n consecutive time slots, downlink channel format 2 occupies M consecutive time slots, downlink channel format 3 occupies X consecutive time slots, and downlink channel format 4 occupies Y consecutive time slots.

[0460] Optional Example 2: Define multiple downlink channels, each of which transmits one or more specific downlink information.

[0461] Example 1: Define downlink control channel, downlink data channel, downlink broadcast channel, etc. Each channel can only transmit one specific information

[0462] 1. The downlink control channel only transmits control information, the downlink data channel only transmits data information, and the downlink broadcast channel only transmits system broadcast information.

[0463] 2. Different downlink channels occupy different time-frequency resources. For example, the time domain resources of the downlink control channel and the downlink data channel are located in different time slots / subframes. (Considering that AIOT has low latency requirements, control and data are not located in one time slot, AIOT does not need strong processing capabilities, which can reduce the complexity of the terminal.) For example, the time domain resources of the downlink control channel and the downlink broadcast channel are located in different time slots / subframes (i.e., the downlink control channel and the downlink broadcast channel will not be located in the same time slot / subframe).

[0464] 3. Downlink control channels, data channels, and broadcast channels can occupy an integer number of time slots in the time domain (longer time in the time domain can improve coverage, and AIOT has relatively high coverage requirements)

[0465] Embodiment 2: Only a downlink control channel and a downlink data channel are defined, and each channel can only transmit one specific information.

[0466] 1. Downlink broadcast channels are not defined. Downlink synchronization is achieved by adding a preamble or frame-sync before sending downlink signaling / data.

[0467] 2. Exemplarily, the preamble is a high-low pulse with a duration of t1, the frame-sync is a high-low pulse with a duration of t2, and t1 is not equal to t2; Exemplarily, the preamble is an OFDM symbol with a duration of t1, the frame-sync is an OFDM symbol with a duration of t2, and t1 is not equal to t2;

[0468] Example 3: Only the downlink broadcast channel and the first downlink channel are defined. The first downlink channel can transmit control information and data information.

[0469] 1. Control information and data information transmitted on the first channel are transmitted using different channel formats. For example, control information is transmitted using first downlink channel format 1, and data information is transmitted using first downlink channel format 2. Information in first downlink channel format 1 and first downlink channel format 2 is scrambled using different RNTIs, or scrambled using CRCs of different lengths, or using different modulation and coding schemes.

[0470] 2. Exemplarily, different first downlink channel formats occupy different amounts of time domain resources (symbols, time slots, subframes, milliseconds, seconds, etc.) and frequency domain resources (such as subcarriers, RBs, bandwidth, etc.).
