Problems solved by technology

[0002] In a communication system, data transmission is required between network equipment and terminal equipment to achieve the purpose of communication. However, when the reliability of data transmission between network equipment and terminal equipment is not high, the transmitted data will be delayed or lost. , so that the terminal device or network device cannot perform corresponding operations according to the received data, and the purpose of communication cannot be achieved

Embodiment 1

[0046] In a possible implementation manner, the determining, based on the DCI and / or high-layer configuration information, determines the time slot for repeated transmission of the PUSCH, including:

[0047] taking the first time slot indicated by the DCI indication and / or the high layer configuration information as the first time slot;

[0048] In the case that the first symbol corresponding to the first time slot satisfies the first condition and the first symbol satisfies the second condition, it is determined that the first time slot is a time slot for repeatedly transmitting the PUSCH, the first time slot is A symbol is a symbol for transmitting the PUSCH indicated by the DCI indication and / or the higher layer configuration information in the symbol corresponding to the first time slot;

[0049] It is determined that the next time slot of the first time slot is the first time slot, until the number of the first time slots in which the PUSCH is repeatedly transmitted is a ...

[0068] In the case that the first symbol corresponding to the first time slot satisfies the first condition and the first symbol satisfies the second condition, it is determined that the first time slot is a time slot for repeatedly transmitting the PUSCH, the first time slot is A symbol is a symbol for transmitting the PUSCH indicated by the DCI indication and / or the higher layer configuration information in the symbol corresponding to the first time slot;

[0069] It is determined that the next time slot of the first time slot is the first time slot, until the number of the first time slots in which the PUSCH is repeatedly transmitted is a ...

Embodiment 3

[0080] In a possible implementation manner, the determining, based on the high-layer configuration information, the time slot for repeated transmission of the PUSCH includes:

[0081] Taking the first time slot indicated by the high layer configuration information as the first time slot;

[0082] In the case that the first symbol corresponding to the first time slot satisfies the first condition and the first symbol satisfies the second condition, it is determined that the first time slot is a time slot for repeatedly transmitting the PUSCH, the first time slot is A symbol is the symbol for transmitting the PUSCH indicated by the high layer configuration information in the symbol corresponding to the first time slot;

[0083] It is determined that the next time slot of the first time slot is the first time slot, until the number of the first time slots in which the PUSCH is repeatedly transmitted is a first preset number.

[0084] Wherein, the PUSCH is a GC-PUSCH other than t...

Abstract

The embodiment of the invention provides a data transmission method and device. The method comprises the following steps: receiving downlink control information (DCI) and / or high-level configuration information; and determining a time slot for repeatedly transmitting a physical uplink shared channel (PUSCH) based on the DCI and / or the high-level configuration information. According to the embodiment of the invention, the data transmission reliability can be improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a data transmission method and device. Background technique [0002] In a communication system, data transmission needs to be performed between network equipment and terminal equipment to achieve the purpose of communication. However, when the reliability of data transmission between network equipment and terminal equipment is not high, the transmitted data will be delayed or lost. , so that the terminal device or the network device cannot perform corresponding operations according to the received data, thus failing to achieve the purpose of communication. SUMMARY OF THE INVENTION [0003] Embodiments of the present application provide a data transmission method and apparatus, which are used to improve the reliability of data transmission. [0004] In a first aspect, an embodiment of the present application provides a data transmission method, which inc...
