Problems solved by technology

[0005] At present, regarding the repeated transmission of uplink data, only the scheme of repeated transmission of corresponding time-domain symbols in different time slots has been formulated, and the scheme of repeated transmission in a single time slot has relatively large restrictions. In the event of a conflict, the entire uplink data transmitted repeatedly will be discarded, which is undoubtedly a great waste of network resources

[0053]This embodiment provides a repeated transmission method, please refer to figure 1 , the repeated transmission method includes:

[0054] S101. Determine each transmission opportunity TO of the uplink data to be repeatedly transmitted;

[0055] S102. Among all the TOs of the uplink data to be repeatedly transmitted, when at least one TO does not conflict with the configured frame structure transmission direction, perform repeated transmission of the uplink data on the TO.

[0056] In some embodiments, performing repeated transmission of uplink data on the TO may include:

[0057] The uplink data that will be repeatedly transmitted is transmitted from the earliest TO in the time domain that does not conflict with the configured frame structure transmission direction. The transmission direction of the configured frame structure may include uplink U, downlink D, and flexibly configured F direction; for the uplink data repeatedly transmitted in each embodiment of the present...

[0099] This embodiment provides a repeated transmission method, please refer to figure 2 , the repeated transmission method includes:

[0100] S201. Determine each TO of the uplink data to be repeatedly transmitted;

[0101] S202. Among all the TOs of the uplink data to be repeatedly transmitted, when at least one TO does not conflict with the configured frame structure transmission direction, receive the uplink data for repeated transmission through the TO.

[0102] In some embodiments, receiving repeatedly transmitted uplink data through the TO includes: when at least one time-domain symbol in the TO collides with the configured transmission direction of the frame structure, performing rate matching on non-conflicting time-domain symbols in the TO.

[0103] In some embodiments, performing rate matching on non-conflicting time-domain symbols in the TO includes: the modulation order in the MCS parameter configured by RRC is unchanged, and a new code rate is calculated accord...

[0117] This embodiment provides a repeated transmission method. According to the first stage of 5G standards, for a certain TB, the first transmission of the terminal can only be at the time domain position corresponding to RV=0. The following are all described by taking the number of repetitions K=4 as an example.

[0118] RV pattern={0231}, such as image 3 As shown, when TO#1~TO#4 correspond to RV index = 0, 2, 3, 1 respectively, and the time domain symbol where TO#1 is located collides with the dynamic SFI, then it needs to be deferred to the TO that can transmit PUSCH , and RV index=0 is also extended to the TO. That is, RV index=0 on TO#1 is extended to TO#2. Then the terminal sends TB to start the first transmission on TO#2.

[0119] RV pattern={0303}, such as Figure 4 As shown, when TO#1~TO#4 correspond to RV index = 0, 3, 0, 3 respectively, and the time domain symbols where TO#1~TO#3 are located all collide with dynamic SFI, then TO#1 needs to be The correspond...

Abstract

The embodiment of the invention provides a repeated transmission method and device, network equipment and a storage medium. The method comprises the following steps: determining each transmission opportunity TO of uplink data to be repeatedly transmitted; when at least one TO in all the TOs of the uplink data to be repeatedly transmitted does not conflict with the transmission direction of the configured frame structure, repeatedly transmitting the uplink data on the TO, so that the uplink data is repeatedly transmitted, the uplink data which is repeatedly transmitted is prevented from being directly discarded when a conflict exists, network resources are saved, and user experience is ensured.
