Claim:
1. A method comprising: receiving control beam transmissions by a radio frequency (RF) receiver of a user equipment (UE) from a base station in a beamforming OFDM network, wherein a pilot signal is transmitted over periodically allocated time-frequency resource blocks associated with a set of beamforming weights of a control beam in a cell; processing pilot symbols carried in a pilot part of a resource block by a radio signal processor of the UE, wherein the pilot part comprises M pilot structures and each pilot structure comprises L OFDM symbols in time domain and R subcarriers in frequency domain, wherein the pilot symbols are inserted once every K subcarriers for R times in each OFDM symbol such that the same pilot symbols are repeated for L times in each pilot structure, and wherein M, L, R, and K are positive integers; and detecting the control beam and the pilot signal by a radio signal detector of the UE based on the control beam transmission, wherein each pilot symbol in each of the m
