Description

Signal sending method, signal receiving method, electronic device and storage medium TECHNICAL FIELD

[0001] The present application relates to the technical field of wireless communication, for example, to a signal sending method, a signal receiving method, an electronic device and a storage medium. BACKGROUND

[0002] In the random access process of the time slot-based ALOHA algorithm or Q-selection algorithm in the passive Internet of Things communication technology, a reader sends a paging signal, and the paging signal indicates a time slot value range of a round to start a random access process of the round. A terminal device randomly selects a time slot value in the time slot value range and stores the time slot value. Then, the base station traverses each time slot value by sending a time slot decrement command. Each time the time slot decrement command is sent, the terminal device triggers the terminal device to decrease the stored time slot value by 1. When the terminal device stored time slot value decreases to 0, the terminal device sends a response signal. However, because the terminal device has very small energy storage, in some network systems, the terminal device often has a power shortage shutdown situation, or the terminal device uses a communication function switch state period switching situation. In the case of shutdown or communication function off, the terminal device cannot receive the paging signal sent by the reader, thereby missing the random access process. SUMMARY

[0024] In the following description, suffixes such as "module", "part", or "unit" used for elements are merely intended for facilitating explanation of the present application, and have no particular meaning by themselves, and thus, "module", "part", or "unit" can be used interchangeably.

[0025] FIG. 1 is a flow chart of a signal sending method according to an embodiment of the present application, which can be applied to a case where a control device receives a paging signal, and the method can be performed by a signal sending device, which can be implemented by a software and / or hardware method, and can be generally integrated in a reader / writer. As shown in FIG. 1, the method according to an embodiment of the present application specifically includes:

[0026] 110, the first node sends a paging signal, wherein the paging signal includes first indication information and first identification information; the first indication information is used to indicate a time domain resource quantity, and the first identification information is used to indicate whether the paging signal is a first paging signal or a second paging signal.

[0027] The first paging signal is a first paging signal in a round of random access procedures, and the second paging signal is an Nth paging signal in a round of random access procedures, wherein N is greater than or equal to 2; the time domain resource quantity indicated by the first indication information in the second paging signal is less than the time domain resource quantity indicated by the first indication information in the first paging signal.

[0028] The first node can send a paging signal to the second node, the paging signal can include first indication information and first identification information, wherein the first indication information is used to indicate the number of time domain resources. The first indication information directly or indirectly indicates the number of time domain resources, and the number of time domain resources can be determined according to the first indication information. The number of time domain resources is used for the second node to determine a time domain resource in the time domain resource range corresponding to the number of time domain resources, and store the time domain resource value, that is, the index or serial number of the time domain resource. For example, the second node determines that the number of time domain resources is S according to the first indication information, and can determine that the time domain resource range corresponding to the number of time domain resources S is time domain resource 0 to S-1, wherein 0 to S-1 represents the index of the time domain resource, which can also be called the time domain resource value or the time domain resource serial number; the second node randomly selects a time domain resource value in the range of time domain resource values 0 to S-1 and stores it.

[0029] In some embodiments of the application, the first identification information is used to indicate that the paging signal is a first paging signal or a second paging signal, the first paging signal is the first paging signal in a round of random access (Random access) process, and the second paging signal is the Nth paging signal in a round of random access process, N is greater than or equal to 2; the number of time domain resources indicated by the first indication information in the second paging signal is less than the number of time domain resources indicated by the first indication information in the first paging signal. Wherein, the random access process is the inventory process.

[0030] The time domain resource is a time domain unit, for example, a time slot (slot) or an access occasion in slot-ALOHA or Q-selection algorithm. The lengths of different time domain resources can be equal or unequal, and the start or end of a time domain resource can be determined according to the first signal or the paging signal. Each first signal or paging signal corresponds to a time domain resource, and each time the first node sends a first signal or a paging signal, it indicates the start of a new time domain resource.

[0031] In some embodiments of the application, sending the paging signal includes: after sending the first paging signal, sending the second paging signal in a round of random access process corresponding to the first paging signal.

[0032] The first node sends the first paging signal to start a round of random access process, and the first node sends the second paging signal in a round of random access process corresponding to the first paging signal.

[0033] On the basis of the application examples, the following at least one is further included: the time domain resource quantity indicated by the first indication information in the first paging signal is the total time domain resource quantity of a round of random access process corresponding to the first paging signal; and the time domain resource quantity indicated by the first indication information in the second paging signal is the time domain resource quantity remaining after the second paging signal in a round of random access process corresponding to the first paging signal.

[0034] On the basis of the application examples, the time domain resource quantity indicated by the first indication information in the second paging signal is equal to K-A-B-1 or K-A-i or K-A; wherein K is the time domain resource quantity indicated by the first indication information in the first paging signal, A is the quantity of the first signals that have been sent before the second paging signal in a round of random access process corresponding to the first paging signal, B is the quantity of the second paging signals that have been sent before the second paging signal in a round of random access process corresponding to the first paging signal, and i represents the i-th second paging signal sent in the round of random access process.

[0035] In one example, the time domain resource quantity indicated by the first indication information in the second paging signal is equal to K-A-B-1, K is the time domain resource quantity indicated by the first indication information in the first paging signal, A is the quantity of the first signals that have been sent before the second paging signal in the round of random access process, and B is the quantity of the second paging signals that have been sent before the second paging signal in the round of random access process.

[0036] Alternatively, the time domain resource quantity indicated by the first indication information in the second paging signal is equal to K-A-i, K is the time domain resource quantity indicated by the first indication information in the first paging signal, A is the quantity of the first signals that have been sent before the second paging signal in the round of random access process, and i represents the i-th second paging signal sent in the round of random access process.

[0037] Alternatively, the time domain resource quantity indicated by the first indication information in the second paging signal is equal to K-A, K is the time domain resource quantity indicated by the first indication information in the first paging signal, and A is the quantity of the first signals that have been sent before the second paging signal in the round of random access process.

[0038] On the basis of the application examples, the following at least one is further included: after sending the paging signal, the first signal is sent, and the first signal triggers the second node to reduce the stored time domain resource value.

[0039] The first node sends the first signal after sending the paging signal, and the first signal triggers the second node to reduce the stored time slot value.

[0040] The second node determines a time domain resource within a time domain resource range, and each time the first signal is received, the stored time domain resource value is reduced until the stored time slot value is reduced to 0, and the second signal is sent; the second signal contains a temporary identifier (ID) or a fixed identifier of the second node; the fixed identifier can be an electronic product code, a unique identifier, or a permanent ID of the second node; the temporary identifier is a temporary identifier of the second node, for example, the temporary identifier contains a random number generated by the second node. In an example, the second signal is a message 1 (Msg1) in an ambient internet of things (Ambient IoT).

[0041] In an example, the first node can detect the second signal sent by the second node after sending each first signal. If the first node correctly decodes the second signal, the second signal is sent. After the second node receives the second signal, the third signal is sent, and the third signal contains the fixed identifier of the second node, which can be an electronic product code, a unique identifier, or a permanent ID of the second node; the first node receives the third signal. Thus, in a time domain resource, the four-step access process of the second node is completed; thereafter, the first node can send the next first signal or a paging signal to start the next time domain resource.

[0042] In another example, the first node can detect the second signal sent by the second node after sending each first signal, and the second signal contains the fixed identifier of the second node, which can be an electronic product code, a unique identifier, or a permanent ID of the second node; the first node receives the second signal. Thus, in a time domain resource, the two-step access process of the second node is completed; thereafter, the first node can send the next first signal or a paging signal to start the next time domain resource.

[0043] In yet another example, the first node can detect the second signal sent by the second node after sending each first signal. If the first node does not correctly decode the second signal (for example, there is no second node sending a signal in the time domain resource, or the first node fails to decode the second signal, etc.), the next first signal or paging signal can be sent to start the next time domain resource.

[0044] In some embodiments, the first paging signal in the paging signal is 1 bit, and the value of the first identification information is 0, and the paging signal is the first paging signal; the value of the first identification information is greater than 0, and the paging signal is the second paging signal.

[0045] In some embodiments of the application, the first identification information is n-bit information, where n is greater than 1. When the value of the first identification information is 0, it indicates that the paging signal is the first paging signal; and when the value of the first identification information is greater than 0, it indicates that the paging signal is the second paging signal.

[0046] FIG. 2 is a flow chart of a signal receiving method according to an embodiment of the application. The embodiment of the application can be applied to the case where a control device receives a paging signal. The method can be executed by a signal receiving apparatus, which can be implemented by software and / or hardware and can be integrated into a terminal device. As shown in FIG. 2, the method according to the embodiment of the application specifically includes the following steps.

[0047] 210. The second node receives a paging signal, where the paging signal includes first indication information and first identification information. The first indication information is used to indicate the number of time domain resources, and the first identification information is used to indicate whether the paging signal is the first paging signal or the second paging signal. The first paging signal is the first paging signal in a round of random access processes, and the second paging signal is the Nth paging signal in a round of random access processes, where N is greater than or equal to 2. The number of time domain resources indicated by the first indication information in the second paging signal is less than the number of time domain resources indicated by the first indication information in the first paging signal.

[0048] In the embodiment of the application, the second node can receive a paging signal sent by the first node, where the paging signal can include first indication information and first identification information. The first indication information is used to indicate the number of time domain resources. The first indication information directly or indirectly indicates the number of time domain resources, and the number of time domain resources can be determined according to the first indication information. The number of time domain resources is used for the second node to determine a time domain resource within the time domain resource range corresponding to the number of time domain resources and store the time domain resource value, where the time domain resource value is the index or serial number of the time domain resource. For example, if the second node determines that the number of time domain resources is S according to the first indication information, it can be determined that the time domain resource range corresponding to the number of time domain resources S is time domain resource 0 to S-1, where 0 to S-1 represents the index of the time domain resource, which can also be referred to as the time domain resource value or the serial number of the time domain resource; and the second node randomly selects a time domain resource value within the range of 0 to S-1 and stores it.

[0049] In some embodiments of the application, the first identification information is used to indicate whether the paging signal is the first paging signal or the second paging signal. The first paging signal is the first paging signal in a round of random access processes, and the second paging signal is the Nth paging signal in a round of random access processes, where N is greater than or equal to 2. The number of time domain resources indicated by the first indication information in the second paging signal is less than the number of time domain resources indicated by the first indication information in the first paging signal. The random access process is an inventory process.

[0050] The time domain resource is a time domain unit, for example, a time slot (slot) or an access occasion in the slot-ALOHA or Q-selection algorithm. The lengths of different time domain resources can be equal or unequal, and the start or end of a time domain resource can be determined according to the first signal or the paging signal. It can be understood that each first signal or paging signal corresponds to a time domain resource, and each time the first node sends a first signal or a paging signal, a new time domain resource starts.

[0051] In some application embodiments, the first identification information in the paging signal indicates that the paging signal is a first paging signal, the number of time domain resources is determined according to the first indication information in the paging signal, a time domain resource is determined within the time domain resource range corresponding to the number of time domain resources, and the time domain resource value of the time domain resource is stored.

[0052] In the embodiment, when the first identification information in the paging signal indicates that the paging signal is a first paging signal, the number of time domain resources S is determined according to the first indication information in the paging signal, so that the time domain resource range corresponding to the number of time domain resources S is time domain resources 0 to S-1, where 0 to S-1 represent the index of the time domain resource, which can also be referred to as the time domain resource value or the time domain resource serial number.

[0053] The time domain resource is determined within the time domain resource range corresponding to the number of time domain resources, including determining a time domain resource value within the range of time domain resource values 0 to S-1 and storing it, for example, randomly selecting a time domain resource value from the time domain resource values 0 to S-1 and storing it.

[0054] The time domain resource is a time domain unit, for example, a time slot (slot) or an access occasion in the slot-ALOHA or Q-selection algorithm. The lengths of different time domain resources can be equal or unequal, and the start or end of a time domain resource can be determined according to the first signal or the paging signal. It can be understood that each first signal or paging signal corresponds to a time domain resource, and each time the first node sends a first signal or a paging signal, a new time domain resource starts.

[0055] In some application embodiments, the first identification information in the paging signal indicates that the paging signal is a first paging signal, the number of time domain resources is determined according to the first indication information in the paging signal, a time domain resource is determined within the time domain resource range corresponding to the number of time domain resources, and the time domain resource value of the time domain resource is stored.

[0056] In the embodiment, the first node transmits the first signal and the second paging signal after transmitting the first paging signal. If the second node receives the paging signal for the first time in the random access process, and the first identification information in the paging signal indicates that the paging signal is the second paging signal, it is indicated that the second node has missed the paging signal transmitted by the first node before the second paging signal, and therefore, the second node determines the time domain resource quantity Z according to the first indication information of the received paging signal for the first time, so as to determine that the time domain resource range corresponding to the time domain resource quantity Z is time domain resources 0 to Z-1, wherein 0 to Z-1 represent the index of the time domain resource, which can also be referred to as the time domain resource value or the time domain resource serial number.

[0057] The method further includes determining a time domain resource in the time domain resource range corresponding to the time domain resource quantity, including: determining a time domain resource value in the range of 0 to Z-1 and storing, for example, randomly selecting a time domain resource value in the range of 0 to Z-1 and storing.

[0058] The time domain resource is a time domain unit, which can be a time slot, a subframe, an orthogonal frequency division multiplexing (OFDM) symbol or a chip length, for example, a time slot (slot) or an access occasion in the slot-ALOHA or Q-selection algorithm. The lengths of different time domain resources can be equal or unequal, and the start or end of a time domain resource can be determined according to the first signal or the paging signal.

[0059] In some embodiments of the application, the method further includes: if the first identification information in the paging signal indicates that the paging signal is the second paging signal, and the paging signal is not the paging signal received by the second node for the first time, reducing the stored time domain resource value.

[0060] If the first identification information in the paging signal received by the second node indicates that the paging signal is the second paging signal, and the paging signal is not the paging signal received by the second node for the first time, the first received paging signal can include the first paging signal or the second paging signal, the stored time domain resource value is reduced, for example, reduced by 1.

[0061] FIG. 3 is a flowchart of another signal transmission method according to an embodiment of the application. The embodiment of the application can be applied to the case that the control device receives a paging signal. The method can be executed by a signal transmission device, which can be implemented by a software and / or hardware method, and can be integrated into a reader / writer.

[0063] The first indication information is used to indicate the time domain resource quantity. The first indication information directly or indirectly indicates the time domain resource quantity, and the time domain resource quantity can be determined according to the first indication information. The time domain resource quantity is used for the second node to determine a time domain resource in a time domain resource range corresponding to the time domain resource quantity, and store a time domain resource value, that is, an index of the time domain resource. For example, the second node determines that the time domain resource quantity is S according to the first indication information, and then determines that the time domain resource range corresponding to the time domain resource quantity S is time domain resources 0 to S-1, wherein 0 to S-1 represent the index of the time domain resource, which can also be referred to as the time domain resource value or the time domain resource serial number; the second node randomly selects a time domain resource value in the range of 0 to S-1 and stores it. The second identification information can be used to indicate a round of random access process. When two paging signals correspond to different random access processes, the values of the second identification information of the two paging signals can be different.

[0064] In the embodiments of the present application, the first node can send a paging signal to one or more second nodes, and the paging signal can comprise first indication information and second identification information. The first indication information is used to indicate a time domain resource quantity, and a value of the second identification information corresponds to a round of random access process.

[0065] In some embodiments of the present application, the method further comprises: in a round of random access process, sending N paging signals, N being greater than or equal to 2; wherein the time domain resource quantity indicated by the first indication information in the nth paging signal is greater than the time domain resource quantity indicated by the first indication information in the n+1 paging signal, 1≤n≤N-1.

[0066] In a round of random access process, the first node sends N paging signals, and the time domain resource quantity indicated by the first indication information in the paging signal sent first is greater than the time domain resource quantity indicated by the first indication information in the paging signal sent subsequently.

[0067] In some embodiments of the present application, the value of the second identification information corresponds to a round of random access process, and includes at least one of the following: within a round of random access process, the values of the second identification information contained in different paging signals are the same; between two adjacent rounds of random access process, the values of the second identification information contained in different paging signals are different.

[0068] In the embodiments of the present application, the first node sends N paging signals corresponding to a round of random access process, and the values of the second identification information contained in the N paging signals are the same, which can correspond to the above-mentioned round of random access process.

[0069] In some embodiments, the first node sends paging signals corresponding to adjacent two rounds of random access procedures, the paging signals contain second identification information with different values, for example, the first node sends paging signals A, B and C, the paging signals A, B and C correspond to the first round of random access procedures, the second node sends paging signals 1, 2 and 3, the paging signals 1, 2 and 3 correspond to the second round of random access procedures, and the second identification information of the paging signals 1, 2 and 3 can have different values from the paging signals A, B and C.

[0070] On the basis of the above-mentioned embodiments, the method further includes: after sending the paging signal, sending a first signal, the first signal triggering the second node to reduce the stored time domain resource value.

[0071] FIG. 4 is a flowchart of another signal receiving method according to an embodiment of the present application. The embodiment of the present application can be applied to the case where a control device receives a paging signal. The method can be executed by a signal receiving apparatus, which can be implemented by software and / or hardware and can be integrated into a terminal device. As shown in FIG. 4, the method according to the embodiment of the present application specifically includes:

[0072] 410. The second node receives a paging signal, the paging signal including first indication information and second identification information; wherein the first indication information is used to indicate the number of time domain resources, and the value of the second identification information corresponds to a round of random access procedures.

[0073] The first indication information is used to indicate the number of time domain resources. The first indication information directly or indirectly indicates the number of time domain resources, and the number of time domain resources can be determined according to the first indication information. The number of time domain resources is used for the second node to determine a time domain resource within the time domain resource range corresponding to the number of time domain resources, and store the time domain resource value, i.e., the index of the time domain resource. For example, the second node determines that the number of time domain resources is S according to the first indication information, and then determines that the time domain resource range corresponding to the number of time domain resources S is time domain resources 0 to S-1, wherein 0 to S-1 represents the index of the time domain resource, which can also be referred to as the time domain resource value or time domain resource serial number; and the second node randomly selects a time domain resource value within the range of 0 to S-1 and stores it. The second identification information can be used to indicate a round of random access procedures. When two paging signals correspond to different random access procedures, the values of the second identification information of the two paging signals can be different.

[0074] In the embodiment of the present application, the second node can receive a paging signal sent by the first node, and the paging signal can include first indication information and second identification information. The first indication information is used to indicate the number of time domain resources, and the value of the second identification information corresponds to a round of random access procedures.

[0075] In some embodiments of the application, the method further comprises: when the paging signal is the first paging signal received by the second node, determining the number of time domain resources according to the first indication information in the paging signal, determining a time domain resource within the time domain resource range corresponding to the number of time domain resources, and storing the time domain resource value of the time domain resource.

[0076] When the second node receives the paging signal for the first time, the second node can extract the first indication information in the paging signal and determine the number of time domain resources indicated by the first indication information. The second node can select a time domain resource within the time domain resource range corresponding to the number of time domain resources, and store the time domain resource value of the time domain resource.

[0077] In some embodiments of the application, the method further comprises: when the paging signal is the Lth paging signal received by the second node, and the value of the second identification information in the paging signal is different from the value of the second identification information in the (L-1)th paging signal, determining the number of time domain resources according to the first indication information in the paging signal, determining a time domain resource within the time domain resource range corresponding to the number of time domain resources, and storing the time domain resource value of the time domain resource, where L is an integer greater than or equal to 2.

[0078] In the embodiments of the application, when the second node receives the paging signal for the Lth time, where L is an integer greater than or equal to 2, the second node can compare the value of the second identification information in the received paging signal with the value of the second identification information in the (L-1)th received paging signal. If the values are different, the Lth received paging signal corresponds to a new round of random access process, the number of time domain resources can be determined according to the first indication information in the Lth paging signal, the second node can determine a time domain resource within the time domain resource range corresponding to the number of time domain resources, and store the time domain resource value of the time domain resource.

[0079] In some embodiments of the application, the method further comprises: when the paging signal is the Lth paging signal received by the second node, and the value of the second identification information in the paging signal is the same as the value of the second identification information in the (L-1)th paging signal, reducing the stored time domain resource value, where L is an integer greater than or equal to 2.

[0080] In the embodiments of the application, when the second node receives the paging signal for the Lth time, where L is an integer greater than or equal to 2, the second node can compare the value of the second identification information in the received paging signal with the value of the second identification information in the (L-1)th received paging signal. If the values are the same, the Lth received paging signal has the same round of random access process as the (L-1)th received paging signal, and the stored time domain resource value is reduced.

[0081] In an example embodiment, a signal sending method is provided, which is applied to a first node, and the method comprises: sending a paging signal, the paging signal containing first indication information and first identification information.

[0082] In this embodiment, the first indication information is used to indicate the number of time domain resources. The first indication information directly or indirectly indicates the number of time domain resources, and the number of time domain resources can be determined according to the first indication information. The number of time domain resources is used for the second node to determine a time domain resource within the time domain resource range corresponding to the number of time domain resources, and store the time domain resource value, which is the index of the time domain resource.

[0083] In an example, the second node determines that the number of time domain resources is S according to the first indication information, and can determine that the time domain resource range corresponding to the number of time domain resources S is time domain resources 0 to S-1, where 0 to S-1 represents the index of the time domain resource, which can also be referred to as the time domain resource value or the time domain resource serial number; the second node randomly selects a time domain resource value within the range of time domain resource values 0 to S-1 and stores it.

[0084] In this embodiment, the time domain resource is a time domain unit, such as a time slot (slot) or an access occasion in slot-ALOHA or Q-selection algorithm. The lengths of different time domain resources can be equal or unequal, and the start or end of a time domain resource can be determined according to the first signal or the paging signal. Each first signal or paging signal corresponds to a time domain resource, and each time the first node sends a first signal or a paging signal, it indicates the start of a new time domain resource.

[0085] In an example, the first node sends a first signal after sending the paging signal, and the first signal triggers the second node to reduce the stored time slot value.

[0086] After the second node determines a time domain resource within the time domain resource range, it reduces the stored time domain resource value each time it receives a first signal or a second paging signal, and sends a second signal when the stored time slot value is reduced to 0; the second signal contains a temporary identifier (ID) or a fixed identifier of the second node; the fixed identifier can be an electronic product code, a unique identifier, or a permanent ID of the second node; the temporary identifier is a temporary identifier of the second node, for example, the temporary identifier contains a random number generated by the second node. In an example, the second signal is Message 1 (Msg1) in Ambient Internet of Things (Ambient IoT).

[0087] In one example, after sending each first signal or paging signal, the first node can detect a second signal sent by the second node. If the first node correctly decodes the second signal, the first node sends an acknowledgement of the second signal. After the second node receives the acknowledgement of the second signal, the second node sends a third signal, which contains a fixed identification number of the second node. The fixed identification number can be an electronic product code, a unique identification code, or other permanent ID of the second node. The first node receives the third signal. Thus, in one time domain resource, the four-step access procedure of the second node is completed. After that, the first node can send the next first signal or paging signal to start the next time domain resource.

[0088] In another example, after sending each first signal or paging signal, the first node can detect a second signal sent by the second node. The second signal contains a fixed identification number of the second node. The fixed identification number can be an electronic product code, a unique identification code, or other permanent ID of the second node. The first node receives the second signal. Thus, in one time domain resource, the two-step access procedure of the second node is completed. After that, the first node can send the next first signal or paging signal to start the next time domain resource.

[0089] In yet another example, after sending each first signal or paging signal, the first node can detect a second signal sent by the second node. If the first node does not correctly decode the second signal (for example, there is no second node sending a signal in the time domain resource, or the first node fails to decode the second signal, etc.), the first node can send the next first signal or paging signal to start the next time domain resource.

[0090] In this embodiment, the first identification information is used to indicate whether the paging signal is a first paging signal or a second paging signal. The first paging signal is the first paging signal in a round of random access procedure, and the second paging signal is the Nth paging signal in a round of random access procedure, where N is greater than or equal to 2. The number of time domain resources indicated by the first indication information in the second paging signal is less than the number of time domain resources indicated by the first indication information in the first paging signal. The random access procedure is an inventory procedure.

[0091] In this embodiment, sending a paging signal includes: after sending a first paging signal, sending a second paging signal in a round of random access procedure corresponding to the first paging signal.

[0092] That is, the first node sends a first paging signal to start a round of random access procedure, and the second node receiving the first paging signal determines a time domain resource (for example, randomly selects a time domain resource) within the time domain resource range indicated by the first paging signal, and sends a second signal based on the selected time domain resource. In this round of random access procedure, the first node can send a second paging signal to make the second node satisfying the first condition determine a time domain resource (for example, randomly select a time domain resource) within the time domain resource range indicated by the second paging signal, and send a second signal based on the selected time domain resource; the second paging signal makes the second node satisfying the second condition reduce the stored time domain resource value, for example, reduce 1.

[0093] The first condition includes that the paging signal is the first paging signal received by the second node in the random access procedure; and the second condition includes that the paging signal is the non-first paging signal received by the second node in the random access procedure. Wherein, whether the paging signal is the first paging signal or the second paging signal is determined according to the first identification information in the paging signal.

[0094] In this way, the first node can send more paging signals in a round of random access procedure, increase the probability of the second node receiving the paging signal, and make more second nodes or the missed second nodes receive the paging signal and access the network, thereby improving the random access efficiency.

[0095] In one example, the first identification information is 1-bit information, the paging signal is the first paging signal when the first identification information value is 0, and the paging signal is the second paging signal when the first identification information value is 1; or, the paging signal is the first paging signal when the first identification information value is 1, and the paging signal is the second paging signal when the first identification information value is 0.

[0096] In another example, the first identification information is n-bit information, and n is greater than 1. When the value of the first identification information is 0, it indicates that the paging signal is the first paging signal, and when the value of the first identification information is greater than 0, it indicates that the paging signal is the second paging signal.

[0097] In this embodiment, the number of time domain resources indicated by the first indication information in the first paging signal is the total number of time domain resources of a round of random access procedure corresponding to the first paging signal. The number of time domain resources indicated by the first indication information in the second paging signal is equal to the number of time domain resources remaining in a round of random access procedure corresponding to the first paging signal.

[0098] In one example, the first indication information in the second paging signal indicates that the number of time domain resources is equal to K-A-B-1, K is the number of time domain resources indicated by the first indication information in the first paging signal, A is the number of first signals that have been sent before the second paging signal in the round of random access process, and B is the number of second paging signals that have been sent before the second paging signal in the round of random access process.

[0099] Alternatively, the first indication information in the second paging signal indicates that the number of time domain resources is equal to K-A-i, K is the number of time domain resources indicated by the first indication information in the first paging signal, A is the number of first signals that have been sent before the second paging signal in the round of random access process, and i represents the i-th second paging signal sent in the round of random access process.

[0100] For example, the first node sends a first paging signal, and the first indication information in the first paging signal indicates that the number of time domain resources is S; after the first paging signal, the first node sends a first signal; after the first node sends a first signal a, the first node sends a first second paging signal in the round of random access process, and the first indication information in the second paging signal indicates that the number of time domain resources is S-a-1; after the first second paging signal, the first node sends b second paging signals, and the first node sends a second second paging signal in the round of random access process, and the first indication information in the second paging signal indicates that the number of time domain resources is S-(a+b)-2.

[0101] In the embodiment, the first node receiving the signal sent by the second node indicates that the first node correctly decodes the signal or detects the signal. The signal sent by the second node can be a second signal or other possible signals.

[0102] In one example, the paging signal is a paging message in Ambient Internet of Things (Ambient IoT).

[0103] In one example, the second signal is a Message 1 (Msg1) in Ambient IoT.

[0104] In some embodiments, the second node receiving the signal sent by the first node indicates that the second node correctly decodes the signal or detects the signal. The signal sent by the first node can be a paging signal, a first signal, or other possible signals.

[0105] In one example implementation, a signal receiving method is provided, applied to a second node, and the method comprises:

[0106] 1. receiving a paging signal, the paging signal comprising first indication information and first identification information.

[0107] In the embodiment, the first indication information indicates a quantity of time domain resources; and the first identification information indicates whether the paging signal is a first paging signal or a second paging signal. The first paging signal is a first paging signal in a round of random access processes, and the second paging signal is an Nth paging signal in a round of random access processes, where N is greater than or equal to 2. The random access process is a check process.

[0108] 2. In a case where the first identification information in the paging signal indicates that the paging signal is the first paging signal, a quantity of time domain resources is determined according to the first indication information in the paging signal, and a time domain resource is determined in a time domain resource range corresponding to the quantity of time domain resources.

[0109] In the embodiment, in a case where the first identification information in the paging signal indicates that the paging signal is the first paging signal, a random access is performed according to the quantity of time domain resources indicated by the first indication information in the paging signal, that is, a time domain resource is determined in a time domain resource range corresponding to the quantity of time domain resources, and a second signal is sent on the time domain resource.

[0110] In the embodiment, in a case where the first identification information in the paging signal indicates that the paging signal is the first paging signal, a quantity of time domain resources S is determined according to the first indication information in the paging signal, so that a time domain resource range corresponding to the quantity of time domain resources S is time domain resources 0 to S-1, where 0 to S-1 represent indexes of the time domain resources, which can also be referred to as time domain resource values or time domain resource serial numbers.

[0111] The determination of a time domain resource in the time domain resource range corresponding to the quantity of time domain resources includes determining a time domain resource value in a range of 0 to S-1 and storing it, for example, randomly selecting a time domain resource value in the range of 0 to S-1 and storing it.

[0112] The time domain resource is a time domain unit, which can be a time slot (slot), a subframe, an orthogonal frequency division multiplexing (OFDM) symbol or a chip time length, for example, a time slot (slot) or an access occasion in a slot-ALOHA or Q-selection algorithm. The time lengths of different time domain resources can be equal or unequal, and the start or end of a time domain resource can be determined according to the first signal or the paging signal.

[0113] 3. sending a second signal based on the determined time domain resource.

[0114] In the embodiment, the sending of the second signal based on the determined time domain resource comprises: sending the second signal on the time domain resource corresponding to the time domain resource value determined by the second node.

[0115] In one example, the sending of the second signal based on the determined time domain resource comprises: if the second node receives the first paging signal and the time domain resource value determined within the time domain resource range is greater than 0, receiving the first signal and / or the second paging signal sent by the first node, and reducing the stored time domain resource value (for example, reducing the stored time domain resource value by 1) each time the first signal or the second paging signal is received, until the stored time domain resource value is reduced to 0, and then sending the second signal; if the second node receives the first paging signal and the time domain resource value determined within the time domain resource range is equal to 0, sending the second signal.

[0116] In the embodiment, the second node has received the first paging signal; and in a round of random access process corresponding to the first paging signal, if the first node sends the second paging signal, the second node reduces the stored time domain resource value each time the second paging signal is received, for example, reduces the stored time domain resource value by 1.

[0117] In the embodiment, the second signal contains a temporary identifier (ID) or a fixed identifier of the second node; the fixed identifier can be an electronic product code, a unique identifier, or a permanent ID of the second node; the temporary identifier is a temporary identifier of the second node, for example, the temporary identifier contains a random number generated by the second node.

[0118] In one example, the second signal is a Message 1 (Msg1) in Ambient IoT.

[0119] In some embodiments, the reception of the signal sent by the first node by the second node means that the second node correctly decodes the signal or detects the signal. The signal sent by the first node can be a paging signal, a first signal, or other possible signals.

[0120] In one example implementation, another signal receiving method is provided, applied to a second node, and the method comprises:

[0121] 1. Receiving a paging signal, the paging signal containing first indication information and first identification information.

[0122] In the embodiment, the first indication information indicates the number of time domain resources; and the first identification information indicates whether the paging signal is a first paging signal or a second paging signal. The first paging signal is the first paging signal in a round of random access process, and the second paging signal is the Nth paging signal in a round of random access process, where N is greater than or equal to 2. The random access process is a check-in process.

[0123] 2. If the first identification information in the paging signal indicates that the paging signal is the second paging signal, and the paging signal is the first paging signal received by the second node in the random access procedure, determining a time domain resource quantity according to the first indication information in the paging signal, and determining a time domain resource in a time domain resource range corresponding to the time domain resource quantity.

[0124] In the embodiment, if the first identification information in the paging signal indicates that the paging signal is the second paging signal, and the paging signal is the first paging signal received by the second node in the random access procedure, performing random access according to the time domain resource quantity indicated by the first indication information in the paging signal, i.e., determining a time domain resource in a time domain resource range corresponding to the time domain resource quantity, and transmitting the second signal on the time domain resource.

[0125] In the embodiment, the first node transmits the first signal and the second paging signal after transmitting the first paging signal. If the second node receives the paging signal for the first time in the random access procedure, and the first identification information in the paging signal indicates that the paging signal is the second paging signal, it means that the second node has missed the paging signal transmitted by the first node before the second paging signal. Therefore, the second node determines the time domain resource quantity Z according to the first indication information of the first received paging signal, so that the time domain resource range corresponding to the time domain resource quantity Z is time domain resources 0 to Z-1, where 0 to Z-1 represent the index of the time domain resource, which can also be referred to as the time domain resource value or the time domain resource serial number.

[0126] Determining a time domain resource in the time domain resource range corresponding to the time domain resource quantity includes determining a time domain resource value in the range of 0 to Z-1 and storing it, for example, randomly selecting a time domain resource value from 0 to Z-1 and storing it.

[0127] The time domain resource is a time domain unit, which can be a time slot (slot), a subframe, an orthogonal frequency division multiplexing (OFDM) symbol, or a chip length, etc. For example, a time domain resource is a time slot (slot) or an access occasion in the slot-ALOHA or Q-selection algorithm. The lengths of different time domain resources can be equal or unequal, and the start or end of a time domain resource can be determined according to the first signal or the paging signal.

[0128] 3. Transmitting the second signal based on the determined time domain resource.

[0129] In the embodiment, transmitting the second signal based on the determined time domain resource includes transmitting the second signal on the time domain resource corresponding to the time domain resource value determined by the second node.

[0130] In one example, the sending the second signal based on the determined time domain resource comprises: if the second node receives the first paging signal and the determined time domain resource value within the time domain resource range is greater than 0, receiving the first signal and / or the second paging signal sent by the first node, and each time the first signal or the second paging signal is received, the stored time domain resource value is reduced (for example, the stored time domain resource value is reduced by 1), and until the stored time domain resource value is reduced to 0, the second signal is sent; if the second node receives the first paging signal and the determined time domain resource value within the time domain resource range is equal to 0, the second signal is sent.

[0131] In the embodiment, the second node has received one second paging signal; then, each time the second node receives the second paging signal, the stored time domain resource value is reduced, for example, the stored time domain resource value is reduced by 1.

[0132] In the embodiment, the second node has received one second paging signal; then, if the second node receives the first paging signal, the number of time domain resources is determined according to the first indication information in the first paging signal, a time domain resource is determined within the time domain resource range corresponding to the number of time domain resources, and the second signal is sent based on the determined time domain resource.

[0133] In the embodiment, the second signal contains a temporary identifier (ID) or a fixed identifier of the second node; the fixed identifier can be an electronic product code, a unique identifier, or a permanent ID of the second node; the temporary identifier is a temporary identifier of the second node, for example, the temporary identifier contains a random number generated by the second node. In one specific example, the second signal is a Message 1 (Msg1) in Ambient IoT.

[0134] In some embodiments, the reception of the signal sent by the first node by the second node indicates that the second node correctly decodes the signal or detects the signal. The signal sent by the first node can be a paging signal, a first signal, or other possible signals.

[0135] In one example implementation, a signal receiving method is applied to a second node, and the method comprises: receiving a paging signal, the paging signal containing first indication information and first identification information.

[0136] In the embodiment, the first indication information indicates the number of time domain resources; and the first identification information indicates whether the paging signal is a first paging signal or a second paging signal. The first paging signal is the first paging signal in a round of random access process, and the second paging signal is the Nth paging signal in a round of random access process, where N is greater than or equal to 2. The random access process is a check-in process.

[0137] In the embodiment, if the first identification information in the paging signal indicates that the paging signal is the second paging signal, and the paging signal is not the first time the second node receives in the random access procedure, the stored time domain resource value is reduced.

[0138] This is because, in the case that the first identification information in the paging signal indicates that the paging signal is the second paging signal, and the paging signal is not the first time the second node receives in the random access procedure, the second node has received the first paging signal or other second paging signals before the paging signal, and the second node has determined a time domain resource from the time domain resource range in the round of random access procedure in which the paging signal is located. Therefore, after the second node receives the second paging signal, the stored time domain resource value is reduced, and the second node does not need to determine a time domain resource from the time domain resource range again.

[0139] In the embodiment, if the second node receives the first paging signal, the number of time domain resources is determined according to the first indication information in the first paging signal, a time domain resource is determined in the time domain resource range corresponding to the number of time domain resources, and the second signal is sent based on the determined time domain resource.

[0140] In some embodiments, the second node receiving the signal sent by the first node indicates that the second node correctly decodes the signal or detects the signal. The signal sent by the first node can be a paging signal, a first signal, or other possible signals.
