Claim of US Patent No. 10,117,250

1. A User Equipment (UE) comprising:a receiver configured to receive, from a base station, downlink control information comprising uplink resource allocation information, wherein the downlink control information indicates a frequency block count;
a transmitter configured to transmit, to the base station, one of:
(1) a first reference signal generated using a first reference signal sequence having a first sequence length corresponding to a first transmit bandwidth allocated by the uplink resource allocation information, wherein the first transmit bandwidth comprises a set of one or more consecutive resource blocks, if the frequency block count is one, and
(2) a second reference signal generated using a second reference signal sequence having a second sequence length corresponding to a second transmit bandwidth allocated by the uplink resource allocation information, wherein the second transmit bandwidth comprises two sets of one or more resource blocks, wherein each of the two sets of one or more resource blocks comprises one or more consecutive resource blocks, wherein the two sets of one or more resource blocks are separated in frequency, if the frequency block count is more than one.
