Systems/methods of carrier aggregation

摘要

Various embodiments of carrier aggregation are provided that increase communications capacity and throughput. According to some embodiments, a transmitter is configured with a plurality of transmitter chains and, responsive to an aggregate bandwidth and/or frequency content of an overall signal that is to be transmitted by the transmitter, the overall signal is segmented into a plurality of components, each one of which comprises a bandwidth that is smaller than the bandwidth of the overall signal, and is thus transmitted by the plurality of transmitter chains of the transmitter. Accordingly, each component of the plurality of components of the overall signal is processed by a respective transmitter chain of the plurality of transmitter chains. Systems/methods of spatial multiplexing are also provided further increasing network capacity and throughput.

1. A communications method performed by a transmitter that comprises a plurality of transmitter chains, the communications method comprising:
transmitting an overall signal by the transmitter to a receiver by using a first transmitter chain of the plurality of transmitter chains and a second transmitter chain of the plurality of transmitter chains to transmit respective first and second different components of the overall signal over respective first and second mutually exclusive frequencies to the receiver; wherein the communications method further comprises exceeding by the overall signal a limit associated with a subsystem of the transmitter, refraining from transmitting the overall signal via said subsystem of the transmitter, and transmitting a plurality of components of the overall signal via the plurality of transmitter chains thus transmitting the overall signal.
