Claim of US Patent No. 10,560,942

1. A method of providing reference signals with a base station in a wireless telecommunication network, the method comprising:receiving an indication of a frequency offset for each sub-band of a plurality of non-contiguous sub-bands of an allocated frequency band;
determining, based at least in part on the indication of the frequency offset for each sub-band of the plurality of non-contiguous sub-bands, one or more symbols of one or more resource blocks during which a first reference signal is to be transmitted on the allocated frequency band, the allocated frequency band being centered at a center frequency and having a minimum frequency and a maximum frequency; and
transmitting, with the base station and during the determined one or more symbols, the first reference signal on a first portion of the allocated frequency band such that a power of the first reference signal occupies the plurality of non-contiguous sub-bands of the allocated frequency band, the plurality of non-contiguous sub-bands of the allocated frequency band having a total bandwidth of less than a bandwidth of the allocated frequency band.
