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 present invention provides a PUCCH transmission method, a mobile communication terminal and a network side device, the method comprising: determining the target CS parameter corresponding to each symbol according to the initial cyclic shift CS parameter and at least a random value associated with the symbol number; The target CS parameter is sent on PUCCH. Since the embodiment of the present invention adds at least a random value associated with each symbol number on the basis of the initial CS parameters for calculation, it can be obtained that the target CS parameters corresponding to each symbol are different, and then it is determined that NR PUCCHs of different lengths are CS value on each symbol. Therefore, in the embodiment of the present invention, it is possible to ensure that the CS values ​​on different symbols are as different as possible to achieve interference randomization, improve the transmission performance of PUCCH, and ensure the CS values ​​of NR PUCCHs with different lengths on the same symbol The acquisition methods are the same, and are used to support multiplexed transmission of NR PUCCHs with different lengths in the same RB, so as to reduce system PUCCH resource overhead.

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...
