Claim of US Patent No. 10,560,933

1. A method performed by a base station of a cellular communications system, the method comprising:transmitting, on a first subset of orthogonal resources and across a cell sector, a common pilot signal;
transmitting, on a second subset of orthogonal resources, a packet data control channel including an allocation to a user equipment of a third subset of orthogonal resources, wherein the packet data control channel is different from the common pilot signal; and
transmitting, within a time slot and on the third subset of orthogonal resources, data to the user equipment using both a first beam and a second beam simultaneously, wherein the first, second, and third subsets of orthogonal resources are respective first, second, and third subsets of tones within an Orthogonal Frequency Division Multiplexing (OFDM) system.
