Description

Base sequence generation method of uplink signal and communication equipment
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method for generating a base sequence of an uplink signal and a communications device.
Background
With the development of mobile communication service demand, various organizations such as ITU (International telecommunications Union) have started to research New wireless communication systems (i.e., 5G NR, 5Generation New RAT) for future mobile communication systems. A number of different uplink channel transmission formats are proposed in 5G. However, in 5G NR, it is not known how to design a base sequence of length 6 for pilot signal transmission and a base sequence of length 6 for data frequency domain spreading, and therefore, it is necessary to propose a scheme for generating a base sequence of an uplink signal.
Disclosure of Invention
The embodiment of the invention provides a method for generating a base sequence of an uplink signal and communication equipment in terms of a base sequence generation mode of the uplink signal.

indicating the phase of the base sequence.
The method for generating the base sequence of the uplink signal provided by the embodiment of the invention can be applied to mobile communication terminals and network side equipment and is used for generating the base sequence of the uplink signal.
The base sequence may be used to generate different uplink signals, for example, the base sequence may be used as a base sequence with a length of 6 used for pilot signal transmission, or may be used as a base sequence with a length of 6 used for data frequency domain spreading. That is, in the present embodiment, the mobile communication terminal may generate a pilot signal from the base sequence, or may generate a data frequency domain spread signal, which is not limited herein.
It should be noted that the number of groups of the base sequence may be set according to actual needs, for example, in a normal case, the number of groups of the base sequence is 30.
