For example, the chip system may include a chip and may also include other discrete devices.

[0050] In some embodiments, the network device may refer to a centralized unit (CU) of a base station, or a distributed unit (DU) of a base station, or a CU control plane (CU-CP) of a base station, or a DU user plane (CU-up) of a base station, etc.

[0051] It should be understood that the term "and / or" used in the embodiments of this application merely describes an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Furthermore, the character " / " used herein indicates that the associated objects are in an "or" relationship.

[0052] The term "at least one" used in the embodiments of the present application refers to one or more.

[0053] The term "plurality" used in the embodiments of the present application refers to two or more.

[0054] The first, second, etc. descriptions appearing in the embodiments of this application are only for illustration and distinction of the description objects. There is no order, nor does it indicate any special limitation on the number of devices in the embodiments of this application, and cannot constitute any limitation on the embodiments of this application.

[0055] It should be noted that the first communication device in this article may refer to a device in A-IoT, and the first communication device in this article may also be referred to as an Internet of Things device, a passive terminal device, a passive device, etc. The second communication device in this article may refer to a network device. For example, the network device may be directly connected to the first communication device for communication. Alternatively, the second communication device in this article may also refer to an intermediate node device. Specifically, the network device and the first communication device have no direct connection, and the intermediate node device refers to a device used to forward data or signals between the network device and the first communication device. That is, the network device is connected to the first communication device through the intermediate node device. Among them, the intermediate node device may also be referred to as an "intermediate node", "temporary node", "auxiliary node", "auxiliary node", etc. Alternatively, the second communication device in this article may also refer to a terminal device, and the terminal device is directly connected to the first communication device for data and / or signal transmission.

[0056] In one A-IoT application scenario, a first communication device can access a second communication device by responding to a query sent by the second communication device. In other words, the second communication device completes an inventory of the surrounding first communication devices by sending query commands and receiving responses from the first communication device.

[0057] Specifically, the second communication device can perform an inventory of the first communication devices in a time-dispersed manner. More specifically, the second communication device can send a query instruction to a group of first communication devices. The query instruction can include a parameter Q, which can be any natural number between 0 and 15. After receiving the query instruction, each first communication device can randomly select a natural number between 0 and (2Q-1) as the time slot for sending a response to the second communication device. If the random number determined by the first communication device is 0, the first communication device immediately sends a response to the second communication device. In addition, after sending the query instruction, the second communication device can also continuously send query repeat instructions. For first communication devices whose determined random number is not 0, each time they receive the query repeat instruction, they can decrement the random number they determined by 1 and send a response to the second communication device when the random number is 0.

[0058] When there are a large number of first communication devices, if the above method is used, it will take a long time to complete the inventory of all first communication devices, that is, it will take a long time to complete the access of all first communication devices. Therefore, this method of dispersing the time has low inventory efficiency or access efficiency.

[0059] In view of this, in the solution of the embodiment of the present application, the second communication device sends a query instruction to the first communication device, and the query instruction includes a first parameter and a second parameter. The first communication device determines the time domain position of its own response based on the first parameter, and determines the frequency domain position of its own response based on the second parameter and / or the reference frequency domain position, and then sends a response to the first communication device at the determined time domain position and frequency domain position. In the above solution, in addition to the first parameter for determining the time domain position, the query instruction also includes a second parameter. The first communication device can determine the frequency domain position of its own response based on the second parameter and / or the reference frequency domain position, thereby enabling different first communication devices to respond at different time and frequency positions. Therefore, the above solution is beneficial to improving the efficiency of multiple first communication devices accessing the second communication device by breaking up the responses sent by the first communication device in the time domain and frequency domain, or in other words, it is beneficial to improving the efficiency of the second communication device in counting the first communication device.

[0060] The second communication device is described in detail below with reference to the accompanying drawings. In the following embodiments, the actions performed by the first communication device can be performed by the first communication device, a device (e.g., a processor, a chip) in the first communication device, or a chip, and the actions performed by the second communication device can be performed by the second communication device, a device (e.g., a processor, a chip) in the second communication device, or a chip, and the application does not limit this. For the convenience of description, the embodiments provided in this application are described by taking the execution entities as the first communication device and the second communication device as an example.

[0061] Example 1

[0062] 1 , which is a schematic diagram of signaling interaction in a first communication method according to an embodiment of the present application, may include S11 and S12.

[0063] S11: The second communication device sends a query instruction to the first communication device, where the query instruction includes a first parameter and a second parameter. Correspondingly, the first communication device receives the query instruction.

[0064] In a specific implementation, the second communication device may send a query instruction to multiple first communication devices, and the query instruction may be carried in the public information sent by the second communication device. For example, the second communication device may send the query instruction to multiple first communication devices in a broadcast or multicast manner, but is not limited thereto.

[0065] It should be noted that the embodiments of the present application do not limit the method of query instructions, signaling carrying query instructions, etc.

[0066] Specifically, the query instruction includes a first parameter and a second parameter, and the first parameter and the second parameter can be used to determine the response resource of the first communication device. The response resource may include the time domain position and / or frequency domain position of the first communication device to send the response. For ease of description, the first parameter can be represented as Q in the following text. t , the second parameter can be expressed as Q f .

[0067] The first parameter may be a natural number, and the second parameter may also be a natural number. For example, the first parameter may be a natural number less than or equal to X, and the second parameter may be a natural number less than or equal to Y. X is a positive integer, and Y is a positive integer. The values ​​of X and Y are not limited herein.

[0068] Each first communication device that receives the query instruction may determine a response resource based on the first parameter and the second parameter. Specifically, the time domain location at which the response is sent may be determined based on the first parameter, and the frequency domain location at which the response is sent may be determined based on the reference frequency domain location and / or the second parameter.

[0069] The following describes the specific details of determining a response resource based on the first and second parameters, using a first communications device as an example. That is, the first communications device referred to below may be any first communications device that receives a query instruction. For other first communications devices that receive a query instruction, the methods for determining a response resource can be found in the relevant description regarding determining a response resource herein and will not be further elaborated herein.

[0070] Specifically, the time domain position at which the first communication device sends the response is: The time domain unit with sequence number y in the candidate time domain units, y is 0 to The natural numbers between, that is, And y is a natural number.

[0071] It should be noted that the "serial number" in this article can also be called "index", "identification", "number", etc., and this embodiment does not limit this.

[0072] That is, the first communication device can be in the range of 0 to Randomly determine a natural number y between The time domain unit with the sequence number y+ in the candidate time domain units is used as the time domain position for sending the response. It should be noted that, in other embodiments, y can be 1 to A positive integer between .

[0073] It should be noted that the time domain unit in the embodiment of the present application can be a time slot, a symbol, a subframe, a millisecond, a moment determined by a counter, etc., but is not limited thereto. Among them, the moment determined by the counter can refer to the transition from the current time domain unit to the next time domain unit in response to a counter value update (such as a counter plus 1 or a counter minus 1). If it is a moment determined by a counter, the first communication device can send data or a response after the counter reaches a certain condition (such as the counter value is 0).

[0074] In specific implementation, The candidate time domain units can be continuous in time domain. time domain units. Among them, The starting time domain position of a candidate time domain unit can be the reference time domain position, The starting time domain position of a candidate time domain unit is The time domain unit with sequence number 0 among the candidate time domain units. That is, The time domain unit with sequence number 0 in the candidate time domain units may be the reference time domain position. Specifically, the reference time domain position may be configured by the second communication device or defined by the protocol. For example, the reference time domain position may be the time domain unit where the query instruction is located. For another example, The starting time domain position of a candidate time domain unit may also be a time domain position other than the reference time domain position, and the query instruction may include information for indicating the reference time domain position.

[0075] In other embodiments, The candidate time domain units can also be discontinuous in the time domain. For example, two adjacent candidate time domain units may be separated by L time domain units, where L may be a positive integer.

[0076] In other embodiments, The candidate time domain units can also be A time domain unit controlled by a second communication device. Specifically, the first communication device can update the time based on the first message sent by the second communication device. The first message can be a paging message, an inventory message, a query repetition message, etc. Specifically, each time the first communication device receives the first message once, the first communication device considers that it has entered the next time domain unit from the current time domain unit. Accordingly, the first communication device can use a counter to count the received first messages and send a response when certain conditions are met. The certain conditions depend on x determined by the first communication device. For example, the initial value of the counter can be x above, and each time the first message is received, the value of the counter is reduced by 1. When the value of the counter is 0, the first communication device can send a response.

[0077] The following describes in detail how to determine the frequency domain position for sending the response.

[0078] In one example, the frequency domain position at which the first communications device sends a response is: The frequency domain unit with sequence number x in the candidate frequency domain units, x is 0 to The natural numbers between, that is, And x is a natural number. That is, the first communication device can be in the range of 0 to Randomly determine a natural number x between The frequency domain unit with the sequence number x in the candidate frequency domain units is used as the frequency domain position where the response is sent. It should be noted that in other embodiments, x can be 1 to A positive integer between .

[0079] It should be noted that the frequency domain unit in the embodiment of the present application can be a carrier, a subband, a frequency point, a resource block (RB), etc., but is not limited thereto.

[0080] In specific implementation, The candidate frequency domain units can be continuous in the frequency domain. time domain units. Among them, The starting frequency domain position of a candidate frequency domain unit can be a reference frequency domain position. The starting frequency domain position of a candidate frequency domain unit is The frequency domain unit with sequence number 0 among the candidate frequency domain units. That is, The frequency domain unit with the candidate frequency domain unit number 0 may be a reference frequency domain position. The reference frequency domain position may be configured by the second communication device or defined by a protocol. For example, the reference frequency domain position may be the frequency domain unit where the query instruction is located. For another example, The starting frequency domain position of a candidate frequency domain unit may also be a frequency domain position other than the reference frequency domain position, and the query instruction may include information for indicating the reference frequency domain position.

[0081] In other embodiments, The candidate frequency domain units can also be discontinuous in the frequency domain. frequency domain units. For example, The candidate frequency domain units may be determined according to the frequency domain pattern configured by the second communication device. In an example of a frequency domain pattern, each frequency domain unit is separated by a frequency domain interval of d Hz, where d may be a preset value or a broadcast indication value.

[0082] In another example, the first communications device may determine the frequency domain location for sending the response based on its own capabilities.

[0083] Specifically, if the first communication device has the first capability, the first communication device can determine the frequency domain position of the response based on the second parameter. That is, if the first communication device has the first capability, the first communication device can determine the frequency domain position of the response based on the second parameter. Randomly determine a natural number x between The frequency domain unit with sequence number 0 among the candidate frequency domain units is used as the frequency domain position for sending the response.

[0084] Exemplarily, if the first communication device has the first capability, the frequency domain position of the response is: The frequency domain unit with sequence number x in the candidate frequency domain units, x is 1 to That is, if the first communication device has the first capability, the first communication device can be a natural number between 1 and Randomly determine a natural number x between The frequency domain unit with sequence number x in the candidate frequency domain units is used as the frequency domain position where the response is sent by itself.

[0085] If the first communication device does not have the first capability, the first communication device may send a response at the reference frequency domain position. That is, the first communication device determines the frequency domain position of the response as the reference frequency domain position. Exemplarily, if the first communication device does not have the first capability, the first communication device may send a response at the reference frequency domain position. The frequency domain unit with sequence number 0 among the candidate frequency domain units sends a response.

[0086] Specifically, the first capability may include frequency shifting capability. In one example, the reference frequency domain position is the frequency domain position where the query instruction is located. In this case, if the first communication device does not have the frequency shifting capability, the first communication device may use the frequency domain position where the query instruction is located as the frequency domain position of the response; if the first communication device has the frequency shifting capability, the first communication device may use the frequency domain position where the query instruction is located as the frequency domain position of the response. Randomly determine a natural number x between The frequency domain unit with sequence number x in the candidate frequency domain units is used as the frequency domain position where the response is sent by itself.

[0087] In other embodiments, the capability of the first communication device may also be described as the type of the first communication device. That is, the first communication device may determine the frequency domain position for sending a response based on its own type. For example, for a first communication device of type A, the frequency domain position of the response may be a reference frequency domain position. For first communication devices of type B and type C, the frequency domain position of the response may be a reference frequency domain position. A frequency domain unit between .

[0088] It should be noted that the first communication device of type A may refer to a first communication device that completes communication through backscattering, does not have energy storage capabilities, and does not generate independent signals. The first communication device of type B may be a first communication device that completes communication through backscattering, does not generate independent signals, but has energy storage capabilities. The first communication device of type C may be a first communication device that has energy storage capabilities and can independently generate signals. Alternatively, the first communication device of type A is a first communication device that uses backscattering to communicate with an energy consumption of 1 microwatt (or less than 1 microwatt or several microwatts), and the first communication device of type B / C is a first communication device that uses backscattering or actively sends signals with an energy consumption of hundreds of microwatts.

[0089] As described above, after receiving the query instruction, the first communication device can determine the time domain position and frequency domain position at which it sends the response.

[0090] S12: The first communication device sends a response to the second communication device, where the time domain position of the response is determined based on the first parameter, and the frequency domain position of the response is determined based on the reference frequency domain position and / or the second parameter.

[0091] Specifically, each first communication device may send a response to the second communication device on its own response resource to respond to the query instruction.

[0092] Exemplarily, each first communication device may generate a random number based on a specific encoding method, and the response sent may include the generated random number. For example, the random number may be RN16. The specific encoding method may be agreed upon by the protocol or configured by the second communication device.

[0093] Refer to Figure 2, which is a schematic diagram of a response resource in an embodiment of the present application.

[0094] In the solution shown in FIG2 , the query instruction sent by the second communication device includes a first parameter and a second parameter, wherein the first parameter Q t =3, the second parameter Q f = 2. As shown in FIG2 , assuming that eight first communication devices receive a query instruction, the above solution can be used to disperse the eight first communication devices in the time domain and frequency domain, so that the eight first communication devices send responses on the eight response resources shown in FIG2 .

[0095] From the above, in the scheme of embodiment one, the second communication device sends a query instruction, and the first parameter and the second parameter in the query instruction are used to determine the response resource. Each first communication device that receives the query instruction determines the time domain position of the response based on the first parameter, and determines the frequency domain position of the response based on the reference frequency domain position and / or the second parameter. The response sent by the first communication device can be scattered in the time domain and the frequency domain, which is conducive to improving the efficiency of multiple first communication devices accessing the second communication device.

[0096] For more details about the first embodiment, please refer to the relevant descriptions of other embodiments in this document, which will not be repeated here.

[0097] Example 2

[0098] 3, which is a schematic diagram of signaling interaction in a second communication method according to an embodiment of the present application, the method shown in FIG3 may include steps S31 to S33.

[0099] S31: The second communication device sends a query instruction to the first communication device. Correspondingly, the first communication device receives the query instruction.

[0100] S32: The first communication device sends a response to the second communication device, and the second communication device receives the response accordingly.

[0101] For the specific contents of S31 and S32, please refer to the above description of S11 and S12, which will not be repeated here.

[0102] S33: The second communication device sends feedback information to the first communication device, where the feedback information indicates the reception status of the response. Correspondingly, the first communication device receives the feedback information.

[0103] Specifically, after receiving the response, the second communication device may send feedback information to the first communication device to indicate to the first communication device that the response sent by the first communication device has been received. Exemplarily, the second communication device may send feedback information in each time domain unit in which a response is received. The feedback information may be used to indicate the response reception status in that time domain unit. The second communication device may send feedback information in a reference frequency domain position, but is not limited thereto.

[0104] In a specific implementation, the second communication device may send the feedback information by broadcasting, multicasting, or the like.

[0105] Taking a first communication device as an example, combined with the solution of embodiment 1, it is assumed that the time domain position of the first communication device sending the response is The first communication device receives the feedback information on the time domain unit with sequence number y among the candidate time domain units. Specifically, the first communication device may occupy a portion of the time domain resources of the time domain unit with sequence number y to send the response, and receive the feedback information on another portion of the time domain resources of the time domain unit with sequence number y.

[0106] Furthermore, the feedback information may include a reception status of a response sent by at least one first communication device in the time domain unit with sequence number y. Each first communication device may determine the reception status of the response sent by itself from the feedback information.

[0107] In one example, the feedback information may include Information bit groups, wherein each information bit group includes multiple information bits. One information bit group may correspond to one first communication device. In combination with the solution of embodiment 1, the frequency domain position at which the first communication device sends a response is The first communication device can select the frequency domain unit with the sequence number x in the candidate frequency domain units according to The x+1th information bit group in the information bit groups determines the response reception status. That is, each first communication device can determine the information bit group corresponding to itself in the feedback information according to the sequence number of the frequency domain position where it sends the response.

[0108] Exemplarily, an information bit group may carry a random number included in a response sent by a first communications device. For a first communications device that sends a response on a frequency domain unit numbered x, if the first communications device decodes the random number it sent from the x+1th information bit group, it may be determined that the response was successfully received. If the first communications device fails to decode the random number it sent from the x+1th information bit group, it may be determined that the response was unsuccessfully received.

[0109] In conjunction with Figure 2, it is assumed that the first communication device 1 sends a response on time slot 1 and f0, and the first communication device 2 sends a response on time slot 1 and f3. Correspondingly, the second communication device receives responses on f0 and f3 respectively on time slot 1. That is, the second communication device receives two responses sent by the first communication device on time slot 1. Further, the second communication device can send feedback information on time slot 1. The feedback information may include information bit groups, then The first information bit group in the information bit groups may be used to indicate the reception status of the response sent by the first communication device 1. The fourth information bit group in the information bit groups can be used to indicate the reception status of the response sent by the first communication device 2.

[0110] In another example, the feedback information may include information bits, wherein one information bit may correspond to one first communication device. Taking one first communication device as an example, the frequency domain position at which the first communication device sends a response is The first communication device can select a frequency domain unit with a sequence number of x from the candidate frequency domain units. The x+1th information bit among the information bits determines the response reception status.

[0111] For example, for the first communication device that sends a response on the frequency domain unit with sequence number x, if the value of the x+1th information bit is 1, it may indicate that the response sent by the first communication device is received successfully; if the value of the x+1th information bit is 0, it may indicate that the response sent by the first communication device is received unsuccessfully.

[0112] In conjunction with Figure 2, assume that first communication device 1 sends a response in time slot 1 and f0, and first communication device 2 sends a response in time slot 1 and f3. Correspondingly, the second communication device receives responses at f0 and f3 in time slot 1. Furthermore, the second communication device can send feedback information in time slot 1. The feedback information can include four information bits. The first of the four information bits can be used to indicate the reception status of the response sent by first communication device 1, and the fourth information bit can be used to indicate the reception status of the response sent by first communication device 2. Assuming the feedback information is 1001, it can indicate that the responses sent by first communication device 1 and first communication device 2 were both successfully received.

[0113] In another example, the feedback information may include indication information, and the indication information may be used to indicate the type of the feedback information. The type of the feedback information may include a first type and a second type. The first type of feedback information includes information bit groups, and one information bit group corresponds to one first communication device, that is, one information bit group can be used to indicate the reception status of the response sent by one first communication device; the second type of feedback information may include information bits, wherein one information bit corresponds to one first communication device, that is, one information bit can be used to indicate a reception status of a response sent by one first communication device.

[0114] Exemplarily, when the number of received responses is small, the second communication device may send first type of feedback information; when the number of received responses is large, the second communication device may send second type of feedback information.

[0115] From the above, in the solution of the second embodiment, the query instruction includes the second parameter Q f , Q fThe second communication device sends feedback information on the time domain unit where the response is received to indicate the reception status of each response on the time domain unit. The feedback information includes An information bit group, one information bit group is used to indicate the reception status of a response sent by a first communication device, or the feedback information includes information bits, one information bit is used to indicate the reception status of the response sent by a first communication device. The frequency domain unit with sequence number x in the candidate frequency domain units sends a response, then the first communication device The x+1th information bit group in the information bit groups or according to The x+1th information bit among the information bits determines the reception status of the response sent by itself. Using the above solution, when multiple first communication devices send responses at the same time domain position, the response reception status of each first communication device can be accurately indicated through feedback information, which is conducive to solving the problem of downlink collision.

[0116] It should be noted that the "x+1th information bit group" in this document may also be referred to as the information bit group with sequence number x, and the "x+1th information bit" in this document may also be referred to as the information bit with sequence number x.
