Abstract
A data transmission method and a device thereof are provided for tag access. The provided method includes: An answer device receives first signaling sent by a read/write device. The first signaling carries target flag information. The target flag information is used to determine the answer device. First flag information of the answer device matches the target flag information. The answer device determines a first slot, and sends first access information to the read/write device in the first slot. In the provided method, the first slot is determined, to avoid collision of different slots in a same slot in a next round, reduce a collision probability, and improve tag access efficiency.
Claims20
A data transmission method, comprising:
- receiving, by an answer device, first signaling sent by a read/write device, the first signaling carrying target flag information;
- determining, by the answer device, that the target flag information matches a first flag information;
- determining, by the answer device, a first slot based on the target flag information matching the first flag information;
- and
- sending, by the answer device, first access information to the read/write device in the first slot.
A data transmission method, comprising:
- sending, by a read/write device, first signaling to an answer device, the first signaling carrying target flag information, the target flag information is used to determine the answer device;
- and
- receiving, by the read/write device, first access information sent by the answer device if a first flag information of the answer device matches the target flag information.
An answer device, comprising:
- a memory storing instructions;
- and
- at least one processor in communication with the memory, the at least one processor configured, upon execution of the instructions, to perform the following steps:
- receive first signaling sent by a read/write device, the first signaling carrying target flag information;
- determine the target flag information matches a first flag information;
- determine a first slot based on the target flag information matching the first flag information;
- and
- send first access information to the read/write device in the first slot.
A read/write device, comprising:
- a memory storing instructions;
- and
- at least one processor in communication with the memory, the at least one processor configured, upon execution of the instructions, to perform the following steps:
- send first signaling to an answer device, the first signaling carrying target flag information, the target flag information is used to determine the answer device;
- and
- receive first access information sent by the answer device if a first flag information of the answer device matches the target flag information.
