Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. A cellular base station, comprising:
one or more antennas;
transceiver circuitry; and
at least one processor communicatively coupled to the transceiver circuitry and configured to cause the cellular base station to:
encode, for transmission to a user equipment (UE), downlink control information (DCI) scheduling a transmission including uplink shared channel (UL-SCH) data;
receive, from the UE, the transmission including UL-SCH data;
extract, from the transmission, uplink control information (UCI) multiplexed with the UL-SCH data from orthogonal frequency division multiplexing (OFDM) symbols in a time domain and in one or more physical resource blocks (PRBs) in a frequency domain, wherein the OFDM symbols and one or more PRBs include a plurality of time-frequency resource elements (REs);
wherein the transmission includes:
demodulation reference signals (DMRS) mapped to REs in a set of OFDM symbols of the transmission, wherein the set of OFDM symbols is according to the DCI;
first UCI mapped to REs of the OFDM symbols, wherein mapping of the first UCI depends on a position of the DMRS, wherein said mapping includes the first UCI mapped to REs first in the frequency domain and then in the time domain; and
the UL-SCH data mapped to REs of the one or more PRBs first in the frequency domain and then in the time domain after mapping the first UCI.
