Abstract
A transmitter adapted for massive multiple-input multiple-output (M-MIMO) operation includes a first set of power amplifiers (PAs) that amplifies a first signal to produce an amplified first signal, and a second set of PAs that amplifies a second signal to produce an amplified second signal, wherein PAs in the first set of PAs are different from PAs in the second set of PAs. The transmitter includes an antenna array operatively coupled to the first set of PAs and the set of second PAs, the antenna array including a plurality of transmit antennas, wherein the antenna array transmits one or more of the amplified signals.

20. A method for operating a transmitter, the method comprising:
-
determining, by the transmitter, which one of a first signal and a second signal is to be transmitted during a first time interval; amplifying, by the transmitter, the first signal with a first set of power amplifiers (PAs) to produce an amplified first signal in response to determining that the first signal is to be transmitted during the first time interval, thereby producing an amplified first signal; amplifying, by the transmitter, the second signal with a second set of PAs to produce an amplified second signal in response to determining that the second signal is to be transmitted during the first time interval; and transmitting, by the transmitter, one of the amplified first signal and the amplified second signal during the first time interval. - View Dependent Claims (21, 22, 23, 24, 25)
