INFORMATION RECEIVING METHOD, INFORMATION SENDING METHOD, COMMUNICATION NODE AND STORAGE MEDIUM

This application claims priority to Chinese Patent Application No. 202210044515.6 filed Jan. 14, 2022, the disclosure of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present application relates to the field of communication technology, for example, an information receiving method, an information sending method, a communication node, and a storage medium.

BACKGROUND

In radio-frequency identification (RFID), when a reader/writer sends information to a passive terminal individually, the information requires to carry a temporary identifier (ID) associated with the passive terminal. If the passive terminal determines that the received temporary ID is the same as the temporary ID of the passive terminal, it is determined that the information is valid. The temporary ID is generally a random number up to 16 bits generated by the passive terminal and sent to the reader/writer through uplink information. After confirming that the uplink information of the passive terminal is correctly received, the reader/writer may send commands and information to the passive terminal by using the temporary ID. However, the passive communication technology based on a cellular network has a larger coverage area and is connected to more passive terminals. Thus, because of a large number of passive terminals, different passive terminals in RFID may have the same temporary ID and thus cannot be distinguished from each other. Moreover, passive communication uses single-carrier modulation transmission; therefore, the more the bits in data transmission, the longer the transmission duration.

In an information receiving method, an information sending method, a communication node, and a storage medium provided according to embodiments of the present application, a temporary ID is determined by a resource serial number of a transmission resource used for transmission of first information. The temporary ID helps to identify and distinguish between different terminal devices, thereby preventing a temporary-ID conflict between terminal devices. Moreover, this solution can reduce the bit overhead of a dedicated temporary ID in uplink information, reduce the transmission duration, and improve the recognition efficiency.

The following describes the information receiving method, the information sending method, the communication node, and the technical effects thereof.

FIG. 2 is a flowchart of an information receiving method according to an embodiment. As shown in FIG. 2, the method of this embodiment is applied to a first communication node. In this example, the first communication node (also referred to as a first communication node device) may be a base station, and the second communication node (also referred to as a second communication node device) may be a terminal device. The method includes S110 and S120.

In S110, the first communication node receives first information sent by a second communication node.

In an embodiment, the first information may be uplink response information.

In S120, the first communication node determines a temporary ID of the second communication node according to a resource serial number of a transmission resource used for transmission of the first information, where the temporary ID includes a bit sequence corresponding to the resource serial number, and the resource serial number includes at least one of the following: a round serial number, a slot serial number, a group serial number, a spreading code serial number, or a subchannel serial number.

In an embodiment, the resource serial number satisfies at least one of the following features: The resource serial number includes the round serial number, where the round serial number is determined according to the number of times a slot value range is updated; or the resource serial number includes the slot serial number, where the slot serial number is determined according to a slot in which the first information is correctly received; or the resource serial number includes the group serial number, where the group serial number is determined according to a group where the first information is correctly received; or the resource serial number includes the spreading code serial number, where the spreading code serial number is determined according to a spreading code through which despreading is correctly performed; or the resource serial number includes the subchannel serial number, where the subchannel serial number is determined according to a subchannel where the first information is located.

Based on the previous embodiment, FIG. 3 is a flowchart of another information receiving method according to an embodiment. As shown in FIG. 3, the method includes S100, S110, S120, and S130.

In S100, the first communication node sends second information to the second communication node, where the second information includes configuration information of the transmission resource, and the configuration information of the transmission resource includes at least one of the following: the round serial number, slot configuration information, group configuration information, spreading code configuration information, or subchannel configuration information.

The second information may be command information including the configuration information of the transmission resource. The configuration information of the transmission resource includes at least one of the following: the round serial number, slot configuration information, group configuration information, spreading code configuration information, or subchannel configuration information.

In S110, the first communication node receives first information sent by a second communication node.

In an embodiment, the first information includes any one of the following two forms.

Form one: The first information includes the unique product number of the second communication node.

Form two: The first information includes a random number of n bits or n bits in the unique product number of the second communication node.

The temporary ID includes a bit sequence corresponding to the resource serial number, that is, the temporary ID includes at least one of the following: a bit corresponding to the value of the round serial number, a bit corresponding to the value of the slot serial number, a bit corresponding to the value of the group serial number, a bit corresponding to the value of the spreading code serial number, or a bit corresponding to the value of the subchannel serial number.

In the present application, the first communication node determines the resource serial number in the following manner: When the resource serial number includes the round serial number, one round is counted each time the slot value range is updated, and the number of times the slot value range is updated corresponds to the round serial number. For example, sending of the second information by the first communication node for the first time corresponds to the round serial number 0, sending of the second information by the first communication node for the second time corresponds to the round serial number 1, and sending of the second information by the first communication node for the third time corresponds to the round serial number 2. Then, the round serial number of the second communication node may be determined according to the number of times the slot value range is updated; or each time a new round starts, the first communication node notifies the round serial number to the second communication node.

Specifically, after the first communication node correctly receives the first information sent by the second communication node, the current round serial number is determined as the round serial number of the second communication node.

When the resource serial number includes the slot serial number, if the first communication node correctly receives the first information in a slot, the slot serial number of the second communication node that sends the first information is determined according to the slot. For example, the slot value randomly selected by the second communication node is S, the first information is sent in the slot corresponding to the slot value S, and the first communication node correctly receives the first information in the slot. In this case, it is determined that the slot serial number of the second communication node is S.

When the resource serial number includes the group serial number, the first communication node indicates a second communication node group, and the second communication node in the group sends the first information. If the first communication node correctly receives the first information within the time of the group, it is determined that the second communication node that sends the first information has the group serial number of the group.

When the resource serial number includes the spreading code serial number, the first communication node determines the spreading code serial number of the second communication node according to a spreading code through which despreading is correctly performed. Specifically, the first communication node receives the first information and despreads the first information by using the spreading code in the spreading code set, where the serial number corresponding to the spreading code through which the first information is correctly despreaded is the spreading code serial number of the second communication node. Alternatively, with a given spreading code length, spreading codes are in one-to-one correspondence with spreading code serial numbers, and a spreading code serial number can be determined according to a spreading code.

When the resource serial number includes the subchannel serial number, the first communication node determines the subchannel serial number of the second communication node according to the subchannel where the first information sent by the second communication node is located. Specifically, the first communication node receives the first information, and the subchannel serial number of the second communication node is determined according to the subchannel on the frequency domain occupied by the first information. The subchannel is a transmission frequency band in the frequency domain. The subchannel may be a narrowband or a subcarrier.

In an embodiment, the temporary ID also includes the first information. Specifically, the temporary ID includes the bit sequence corresponding to the resource serial number and the bit sequence of the first information.

In S130, the first communication node sends third information to the second communication node, where the third information includes the temporary ID.

After correctly receiving the first information sent by the second communication node and determining the temporary ID of the second communication node, the first communication node sends the third information including the temporary ID to the second communication node.

In an embodiment, the third information may be confirmation information. The third information is used by the second communication node to determine whether the temporary ID determined by the node matches the received temporary ID. If the temporary ID determined by the node matches the received temporary ID, it is determined that the temporary ID and the third information are valid. If the temporary ID determined by the node does not match the received temporary ID, the first information is sent again by using the updated transmission resource.

In an embodiment, if the first information includes n bits in the unique product number of the second communication node, as shown in FIG. 4, a flowchart of another information receiving method according to an embodiment, the method also includes S140.

In S140, the first communication node receives fourth information sent by the second communication node, where the fourth information includes (N−n) remaining bits in the unique product number of the second communication node, where N denotes the number of bits of the unique product number of the second communication node.

If the first information includes n bits in the unique product number of the second communication node, the fourth information requires to include only (N−n) remaining bits in the unique product number of the second communication node, thereby reducing the bit overhead of a dedicated temporary ID in uplink information, reducing the transmission duration, and improving the recognition efficiency.

FIG. 5 is a flowchart of an information sending method according to an embodiment. As shown in FIG. 5, the method of this embodiment is applied to a second communication node. In this example, the first communication node (also referred to as a first communication node device) may be a base station, and the second communication node (also referred to as a second communication node device) may be a terminal device. The method includes S210 and S220.

In S210, the second communication node sends first information to a first communication node.

In an embodiment, the first information may be uplink response information.

In S220, the second communication node determines a temporary ID of the second communication node according to a resource serial number of a transmission resource used for transmission of the first information, where the temporary ID includes a bit sequence corresponding to the resource serial number, and the resource serial number includes at least one of the following: a round serial number, a slot serial number, a group serial number, a spreading code serial number, or a subchannel serial number.

In an embodiment, the resource serial number includes the round serial number, where the round serial number is notified by the first communication node or determined according to the number of times a slot value range is updated.

In an embodiment, the resource serial number includes the slot serial number, where the slot serial number is randomly selected by the second communication node.

In an embodiment, the resource serial number includes the group serial number, where the group serial number is randomly selected by the second communication node; or the group serial number is the serial number of a fixed group of the second communication node; or the group number is determined according to the unique product number of the second communication node.

The operation of determining group number according to the unique product number of the second communication node includes that the second communication node can acquire group indication information, and when the group indication information is the same as a segment of identification bits in the unique product number of the second communication node, the second communication node determines the group serial number as a group serial number corresponding to the group indication information.

When the resource serial number includes the spreading code serial number, the spreading code serial number is randomly selected by the second communication node; or the spreading code serial number is the serial number of a fixed spreading code of the second communication node.

Specifically, if the spreading code serial number is randomly selected by the second communication node, then the second communication node can acquire spreading code length indication information, where the spreading code length indication information indicates a spreading code length, and the spreading code serial number is a serial number of a spreading code randomly selected from a spreading code set corresponding to the spreading code length; or the second communication node can acquire repetition number indication information, where the repetition number indication information indicates the number of repetitions, the number of repetitions determines a spreading code length, and the spreading code serial number is the serial number of a spreading code randomly selected from a spreading code set corresponding to the spreading code length.

In an embodiment, the resource serial number includes the subchannel serial number, where the subchannel serial number is randomly selected by the second communication node; or the subchannel serial number is the serial number of a fixed subchannel of the second communication node.

Based on the previous embodiment, FIG. 6 is a flowchart of another information sending method according to an embodiment. As shown in FIG. 6, the method includes S200, S210, S220, S230, and S240.

In S200, the second communication node receives second information sent by the first communication node, where the second information includes configuration information of the transmission resource, and the configuration information of the transmission resource includes at least one of the following: the round serial number, slot configuration information, group configuration information, spreading code configuration information, or subchannel configuration information.

In S210, the second communication node sends the first information to the first communication node.

After receiving the second information sent by the first communication node, the second communication node sends the first information to the first communication node according to the configuration information of the transmission resource.

When the configuration information of the transmission resource includes the slot configuration information, the slot value range can be determined according to the slot configuration information. That is, after receiving the second information, the second communication node randomly selects a slot value in the determined slot value range and sends the first information in the slot corresponding to the selected slot value.

When the configuration information of the transmission resource includes the group configuration information, the group is a second communication node group, and the group configuration information includes the following modes:

Manner A1: The group configuration information is a piece of group indication information, second communication nodes matching the group indication information belong to one group, and a second communication node in the group sends the first information. That is, after receiving the second information, if the group serial number of the second communication node matches the group indication information, the second communication node sends the first information within the period of the group. The group serial number of the second communication node may be determined by a segment of identification bits included in the second communication node or may be a fixed group serial number.

Mode A2: The group configuration information indicates the number T of groups and is used for dividing second communication nodes into T groups. That is, after receiving the second information, the second communication node randomly selects a group from the T groups and sends the first information within the period of the selected group.

The period of the group includes that each time the first communication node sends the group indication information, the period of the previous group ends, or the period of the next group starts, and the period between two adjacent pieces of group indication information is the period of one group.

When the configuration information of the transmission resource includes the spreading code configuration information, the spreading code length may be determined according to the spreading code configuration information. That is, after receiving the second information, the second communication node determines the spreading code length and sends the first information by using the spreading code corresponding to the spreading code length.

The method for determining the spreading code length according to the spreading code configuration information includes that the spreading code configuration information is spreading code length indication information for indicating the spreading code length; or the spreading code configuration information is repetition number indication information for indicating the number of data transmission repetitions, and the spreading code length is determined according to the number of repetitions, where the number of repetitions is an integer multiple of the spreading code length, and the number of repetitions corresponds to the spreading code length.

Accordingly, the first information may be sent by using the spreading code corresponding to the spreading code length in one of the following manners:

Manner B1: The second communication node randomly selects a spreading code from the spreading code set corresponding to the spreading code length and sends the first information based on the selected spreading code.

Manner B2: The second communication node has a fixed spreading code. Specifically, one second communication node includes N spreading code lengths, each spreading code length corresponds to a fixed spreading code, and after determining the spreading code length, the second communication node sends the first information based on the corresponding spreading code.

Manner B3: The second communication node randomly generates a spreading code with the spreading code length and sends the first information based on the generated spreading code.

When the configuration information of the transmission resource includes the subchannel configuration information, N subchannel serial numbers may be determined according to the subchannel configuration information. That is, after receiving the second information, the second communication node randomly selects a subchannel serial number from the N subchannel serial numbers and sends the first information on the subchannel corresponding to the selected subchannel serial number.

In an embodiment, the first information includes any one of the following two forms.

Form one: The first information includes the unique product number of the second communication node.

Form two: The first information includes a random number of n bits or n bits in the unique product number of the second communication node.

In the present application, the method for determining the resource serial number by the second communication node may include that when the resource serial number includes the round serial number, the round serial number is notified by the first communication node or determined by the number of updates of the slot value range. Each time the slot value range is updated, the round serial number is increased by 1. That is, when sending the first information, the second communication node determines that the current round serial number is the round serial number of the second communication node.

When the resource serial number includes the slot serial number, the second communication node selects a slot value from the slot value range. The selected slot value is the slot serial number of the second communication node.

When the resource serial number includes the group serial number, the second communication node has a fixed group serial number, or the second communication node randomly selects a group serial number, or the group number is determined by the unique product number of the second communication node.

The operation of determining the group number according to the unique product number of the second communication node includes that the second communication node can acquire group indication information, and when the group indication information is the same as a segment of identification bits in the unique product number of the second communication node, the second communication node determines the group serial number as a group serial number corresponding to the group indication information.

When the resource serial number includes the spreading code serial number, the spreading code length is determined according to the second information. In this case, the second communication node has a fixed spreading code with the spreading code length, or a spreading code is randomly selected from the spreading code set corresponding to the spreading code length, or a spreading code with the spreading code length is randomly generated. With a given spreading code length, spreading codes are in one-to-one correspondence with spreading code serial numbers, and a spreading code serial number can be determined according to a spreading code.

The method for determining the spreading code length according to the second information includes that the second information includes spreading code length indication information for indicating the spreading code length; or the second information includes repetition number indication information for indicating the number of data transmission repetitions, and the spreading code length is determined according to the number of repetitions, where the number of repetitions is an integer multiple of the determined spreading code length, and the number of repetitions corresponds to the spreading code length.

When the resource serial number includes the subchannel serial number, the second communication node has a fixed subchannel, or the second communication node randomly selects a subchannel from C subchannels.

In S230, the second communication node receives third information sent by the first communication node, where the third information includes the temporary ID determined by the first communication node.

In S240, the second communication node determines whether the temporary ID included in the third information matches the temporary ID of the second communication node.

In an embodiment, the first communication node may send the third information to the corresponding second communication node based on the temporary ID determined by the first communication node, where the third information sent by the first communication node includes the temporary ID determined by the first communication node.

The third information may be confirmation information about the temporary ID. After receiving the third information, the second communication node determines whether the temporary ID determined by the first communication node matches the temporary ID determined by the second communication node. If the matching is successful, the second communication node determines that the temporary ID is valid. If the matching fails, the second communication node may resend the first information by using an updated transmission resource.

Alternatively, the third information may also be other command information for the second communication node corresponding to the temporary ID, where the command information includes the temporary ID. After receiving the command information, the second communication node determines whether the received temporary ID matches the temporary ID of the second communication node. If the matching is successful, the second communication node determines that the temporary ID is valid. If the matching fails, the second communication node determines that the temporary ID is invalid. In this manner, the first communication node can send information to a single second communication node individually.

In an embodiment, if the first information includes n bits in the unique product number of the second communication node, as shown in FIG. 7, a flowchart of another information sending method according to an embodiment, the method also includes S250.

In S250, if the temporary ID included in the third information matches the temporary ID of the second communication node, the second communication node sends fourth information to the first communication node, where the fourth information includes (N−n) remaining bits in the unique product number of the second communication node, where N denotes the number of bits of the unique product number of the second communication node.

If the first information already includes n bits in the unique product number of the second communication node, the fourth information requires to include only (N−n) remaining bits in the unique product number of the second communication node, thereby reducing the bit overhead of a dedicated temporary ID in uplink information, reducing the transmission duration, and improving the recognition efficiency.

An embodiment of the present application provides an information sending method. The method is applied to a second communication node. The information sending method includes receiving a command sent by a first communication node, where the command includes configuration information of a transmission resource, and the configuration information of the transmission resource includes at least one of the following: slot configuration information, group configuration information, spreading code configuration information, or subchannel configuration information; and sending first information to the first communication node according to the configuration information of the transmission resource.

Specifically, when the configuration information of the transmission resource includes the group configuration information, the second communication node determines the number N of groups according to the group configuration information and randomly selects a value from the N values, where the selected value is the serial number of the selected group. Thus, one second communication node set may be divided into N groups. The second communication node whose group serial number is 0 sends the first information by using a slot, a spreading code, or a subchannel.

In an embodiment, a group count value decrement command sent by the first communication node is received. The group count value decrement command indicates that the group count value of the second communication node is reduced by 1. If the group count value of the second communication node is 0, the first information is sent by using a slot, a spreading code, or a subchannel.

Specifically, when the configuration information of the transmission resource includes the slot configuration information, the second communication node determines the slot value range according to the slot configuration information and randomly selects a slot value from the slot value range. The second communication node whose slot value is 0 sends the first information.

In an embodiment, a slot decrement command sent by the first communication node is received. The slot decrement command indicates that the slot count value of the second communication node is reduced by 1. If the slot count value of the second communication node is 0, the first information is sent.

Specifically, when the configuration information of the transmission resource includes the spreading code configuration information, the second communication node determines the spreading code length according to the spreading code configuration information. Each second communication node has a fixed spreading code with the spreading code length. The second communication node sends the first information based on the spreading code with the spreading code length. Alternatively, the second communication node receives the spreading code configuration information, determines the spreading code length, randomly selects a spreading code from the spreading code set corresponding to the spreading code length, and sends the first information based on the selected spreading code.

Specifically, when the configuration information of the transmission resource includes the subchannel configuration information, the second communication node determines a subchannel set according to the subchannel configuration information, randomly selects a subchannel from the subchannel set, and sends the first information on the selected subchannel.

An embodiment of the present application provides a confirmation method of a temporary ID. The method includes determining the temporary ID of the second communication node according to the resource serial number of a transmission resource used for transmission of the first information by the second communication node. The resource serial number includes at least one of the following: a round serial number, a slot serial number, a group serial number, a spreading code serial number, or a subchannel serial number. The temporary ID includes the bit sequence corresponding to the resource serial number. The bit sequence corresponding to the resource serial number is a binary bit equivalent to the value of the resource serial number.

In an embodiment, if the resource serial number is the slot serial number, the temporary ID includes the bit sequence corresponding to the slot serial number; if the resource serial number is the spreading code serial number, the temporary ID includes the bit sequence corresponding to the spreading code serial number; if the resource serial number is the subchannel serial number, the temporary ID includes the bit sequence corresponding to the subchannel serial number; and if the resource serial number includes two or more of the round serial number, the slot serial number, the group serial number, the spreading code serial number, and the subchannel serial number, the temporary ID includes bit sequences in one-to-one correspondence with the two or more serial numbers. Examples are as follows:
