Embodiment Construction

[0203] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0204] With the development and change of mobile communication service requirements, organizations such as ITU and 3GPP have begun to study new wireless communication systems (such as 5G NR, 5Generation New RAT). A new frame structure is defined in a new wireless communication system, which supports different baseband parameters (numerology, including parameters such as subcarrier spacing, etc.). For different baseband parameters, it is defined that th...

Abstract

The invention provides a PUCCH transmission method, a mobile communication terminal and network side equipment, and the method comprises the steps: determining a target CS parameter corresponding to each symbol according to an initial cyclic shift CS parameter and a random value at least associated with the symbol number; And sending the PUCCH according to the target CS parameter. According to theembodiment of the invention, at least the random value associated with each symbol number is added on the basis of the initial CS parameter for calculation, so that the target CS parameter corresponding to each symbol can be obtained to be different, and the CS values of NR PUCCHs with different lengths on each symbol are determined. Therefore, according to the embodiment of the invention, CS values on different symbols can be ensured to be different as much as possible to achieve RANDOMIZATION OF INTERFERENCE, The transmission performance of the PUCCH is improved, it is ensured that the CS value obtaining modes of the NR PUCCHs with different lengths on the same symbol are the same, the multiplexing transmission of the NR PUCCHs with different lengths in the same RB is supported, and therefore the system PUCCH resource cost is reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a PUCCH transmission method, a mobile communication terminal and network side equipment. Background technique [0002] With the development and change of mobile communication service requirements, organizations such as ITU (International Telecommunication Union, International Telecommunication Union) and 3GPP have begun to study new wireless communication systems (such as 5G NR, 5Generation New RAT). The new wireless communication system defines a PUCCH (Physical Uplink Control Channel) that can occupy 4 to 14 symbols for transmission. The PUCCH may or may not use a frequency hopping structure in a slot. Use a frequency hopping structure. A format in NR PUCCH can be used to carry 1 or 2 bits of information transmission. This format can use BPSK (Binary Phase Shift Keying) or QPSK (Quadrature Phase Shift Keying, four-phase phase shift keying) modulation to obtai...
