Embodiment 1

[0083] If the data resource is a time-domain resource occupied by data, in the embodiment of the present invention, determining the data resource corresponding to the preamble in the uplink data transmission according to the correspondence between the preamble and the data resource stipulated in the protocol includes:

[0084] According to the corresponding relationship between the preamble group and the time domain resource occupied by the data specified in the protocol, and the preamble in the uplink data transmission, determine the time domain resource occupied by the data corresponding to the preamble in the uplink data transmission, wherein each preamble The code group includes at least one preamble;

[0085] The sending uplink data using the determined data resources includes:

[0086] sending the uplink data carried by using the determined time domain resources.

[0087] In the embodiment of the present invention, users can implement data resource multiplexing among us...

Embodiment 2

[0093] If the data resource is a frequency domain resource occupied by data, in the embodiment of the present invention, determining the data resource corresponding to the preamble in the uplink data transmission according to the correspondence between the preamble and the data resource stipulated in the protocol includes:

[0094] According to the corresponding relationship between the preamble group and the frequency domain resource occupied by the data specified in the protocol, and the preamble in the uplink data transmission, determine the frequency domain resource occupied by the data corresponding to the preamble in the uplink data transmission, wherein each preamble The code group includes at least one preamble;

[0095] The sending uplink data using the determined data resources includes:

[0096] sending the uplink data carried by using the determined frequency domain resources.

[0097] In the embodiment of the present invention, data resource reuse between users c...

Embodiment 3

[0103] If the data resource is a data DMRS, in the embodiment of the present invention, according to the corresponding relationship between the preamble and the data resource specified in the protocol, determining the data resource corresponding to the preamble in the uplink data transmission includes:

[0104] Determine the DMRS corresponding to the preamble in the uplink data transmission according to the corresponding relationship between the preamble group and the data DMRS stipulated in the protocol, and the preamble in the uplink data transmission, wherein each preamble group includes at least one preamble ;

[0105] The sending uplink data using the determined data resources includes:

[0106] sending the uplink data modulated by the determined DMRS code.

[0107] In the LTE system, two users can send data signals on the same resource, and the DMRSs of the two users need to be orthogonal. However, the probability of two users using the same resource is small, so there...

Abstract

The invention discloses a data transmission method, device and system. The method comprises the steps of: for uplink data transmission of random access, according to a corresponding relationship of preambles and data resources, which is regulated by a protocol, determining a data resource corresponding to a preamble in the uplink data transmission, wherein different preambles correspond to different data resources; and sending the preamble and uplink data adopting the determined data resource. In the embodiment of the invention, the protocol regulates the corresponding relationship of the preambles and the data resources, for the uplink data transmission of random access, the data resource corresponding to the preamble in the uplink data transmission can be determined, and different preambles correspond to different data resources, and thus, different users can be guaranteed to adopt different data resources to bear the uplink data so as to implement multiplexing of a data part among multiple users.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a data transmission method, device and system. Background technique [0002] With the rapid development of wireless communication technology, terminals (UEs) have entered thousands of households. With the popularity of UEs, UEs have become an indispensable electronic product in people's lives. At present, UE already has a variety of functions. People use the terminal to play games, watch videos, grab red envelopes, rush to buy flash sales within a limited time, etc., which facilitate people's lives. With the popularization and wide application of UEs, users put forward higher and higher requirements for UEs, especially higher requirements for the time delay of data transmission between UEs and base stations (gNBs). [0003] In the existing LTE system, the random access process of the UE adopts a four-step mechanism, such as figure 1 As shown, the four-step ...
