1. A method comprising:

  • transmitting, by a base station, a pilot configuration indicating a pilot signal arrangement, the pilot signal arrangement having been selected from a set of pre-defined pilot signal arrangements according to at least one of a transmission time interval (TTI) length, a mobility of a user equipment (UE), or a modulation and coding scheme (MCS) level over which the UE transmits or receives wireless signals,the pilot signal arrangement having a time domain pilot density defined by a number of pilot symbols of the pilot signal arrangement used within the TTI length, and the time domain pilot density depending on the MCS level; and

    communicating, by the base station with the UE, using a pilot signal according to the pilot signal arrangement,wherein the time domain pilot density of the pilot signal arrangement is a function of the TTI length.
