Abstract

The invention provides a parameter configuration method and device, a parameter receiving method and device and a storage medium, and the parameter configuration method comprises the steps: configuring a reference pilot frequency sequence parameter; reference pilot frequency pseudo-random sequence initial values corresponding to M reference pilot frequency groups are determined according to the reference pilot frequency sequence parameters, the reference pilot frequency pseudo-random sequence initial values are used for generating pilot frequency pseudo-random sequences of the corresponding reference pilot frequency groups, M is a positive integer, and the reference pilot frequency groups at least correspond to one reference pilot frequency port. By adopting the technical scheme, the problem that the PAPR of the reference signal is too high due to the same pilot frequency sequence in the related technology is at least solved, and the PAPR of the reference signal is effectively reduced.

Description

[0001] This application is a divisional application of the Chinese patent application with the application number "201811247396.4", the application date is "October 24, 2018", and the title is "Parameter configuration, parameter receiving method and device, and storage medium". technical field [0002] The present invention relates to the communication field, in particular, to a parameter configuration, a parameter receiving method and device, and a storage medium. Background technique [0003] At present, the wireless communication system has changed from the fourth-generation Long Term Evolution (LTE for short), the long-term evolution upgrade technology (LTE-A, LTE-Advanced), to the current fifth-generation new wireless access technology (NR, New RAT, New Radio Access Technology) development and evolution. In these systems, reference signals need to be sent to estimate channel state information (Channel-State Information, CSI), such as downlink channel state information r...
