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.

Abstract
A method of configuring a pilot signal includes defining a first pilot signal arrangement and defining a second pilot signal arrangement. Also, the method includes determining, by a communications controller, a first determined pilot signal arrangement in accordance with the first defined pilot signal arrangement, the second defined pilot signal arrangement, and a set of characteristics and transmitting, by the communications controller, the pilot signal having the first determined pilot signal arrangement.
