Embodiment Construction

[0077] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0078] The relevant concepts mentioned in the present invention will be described below firstly.

[0079] In 5G NR, PUSCH mapping type A refers to start from OFDM symbol 0 in a slot, length 3-14 OFDM symbols, DMRS (Demodulation Reference Signal, demodulation reference signal) on OFDM symbol 2, PUSCH uses K times For repeated transmission, K is 1, 2, 4, 8, and only one PUSCH repetition can be transmitted in each time slot. For example, if K=4, the PUSCH is transmitted in 4 consecutive time slots. For the first type of uplink scheduling-free transmission scheme, information such as the starting time slot, the number of OFDM symbols occupied in the time slot, and the location of frequency domain resources are notified to the terminal by RRC (Radio Reso...

Abstract

The invention provides a data transmission method and device, and relates to the technical field of communication. The data transmission method is applied to the data transmission device, and comprises the steps of determining a used transmission type during data transmission, the transmission type comprising one of single transmission of target data in one time slot and multiple repeated transmission of the target data in one time slot; when the transmission type is that repeated transmission of the target data is carried out for multiple times in one time slot, determining the number of times of repeated transmission of the target data in each time slot; and transmitting the target data according to the number of times of repeated transmission of the target data in each time slot. According to the scheme, repeated data transmission on one time slot is realized, the network communication process is perfected, and the flexibility of network communication is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and device. Background technique [0002] With the development and change of mobile communication service requirements, many organizations such as 3GPP (3rd Generation Partnership Project, the Third Generation Partnership Project) have begun to study new wireless communication systems (ie, 5G NR (5Generation New Radio Access) for future mobile communication systems. Technology, that is, the 5th generation new wireless access type)). In the 5G NR system, in order to reduce delay, increase reliability, and reduce control signaling overhead, the first type of uplink scheduling-free transmission scheme and the second type of uplink scheduling-free transmission scheme have emerged. [0003] In the 5G NR system, for the resource allocation of the uplink data transmission PUSCH (Physical Uplink Shared Channel, that is, the physical uplink share...
