Abstract

Provided are a method and device for configuring a pilot, wherein the method includes: configuring a user pilot according to subcarrier indexes of REs occupied by the user pilot, wherein the subcarrier indexes of the REs occupied by the user pilot are in subcarrier indexes of REs occupied by user data on PUSCH, and include the following pilot parameters: REstart and RBnumber, and further include REset and/or REinterval; and adjusting power of a pilot at a transmitting end and performing pilot resource mapping according to Powerfactor corresponding to the pilot parameters, where Powerfactor=(REset+REinterval)/REset. Through the disclosure, the problem that a pilot design scheme of the PUSCH in the related art is poor on flexibility is solved.

Dependent claims

A method for configuring a pilot, comprising:

configuring a user pilot according to subcarrier indexes of Resource Elements (REs) occupied by the user pilot, wherein the subcarrier indexes of the REs occupied by the user pilot are in subcarrier indexes of REs occupied by user data on Physical Uplink Shared Channel (PUSCH), and comprise the following pilot parameters:
REstart and RBnumber, and further comprise REset and/or REinterval, wherein the REstart is a subcarrier index of the first RE in the REs occupied by symbols of the user pilot;
the RBnumber is a total number of Resource Blocks (RBs) of symbols of user data;
the REset is a minimum number of REs, of which positions are continuous in a frequency-domain, occupied by the user pilot;
and the REinterval is the number of subcarriers in an interval between two REsets, which are closest in the frequency-domain, of the user pilot;
and
adjusting power of a pilot at a transmitting end and performing pilot resource mapping according to Powerfactor corresponding to the pilot parameters, where Powerfactor=(REset+REinterval)/REset.
