1. A method performed by a wireless communication device, the method comprising:
generating a pilot signal occupying N symbol resources, wherein the pilot signal includes at least one reference signal (RS) port that is determined from a predetermined pool of RS ports, wherein the predetermined pool includes at least N RS ports, wherein N is an integer larger than one; and
transmitting a signal comprising the pilot signal and a data payload to a wireless communication node, wherein the data payload includes information related to the pilot signal and the at least one RS port;
wherein:
each of the RS ports in the predetermined pool has Nz non-zero elements; and
Nz is an integer larger than 0 and less than 4
or:
each of the RS ports in the predetermined pool has Nz non-zero elements;
Nz is an integer larger than 0 and less than 9; and
the Nz non-zero elements of each of the RS ports in the predetermined pool are adjacent in time and/or frequency domain.
