Abstract

Method and apparatus are provided for increasing transmit power in a sub-terahertz (sub-THz) communication system. An apparatus can determine a plurality of component carriers in a single frequency band. The single frequency band comprises an intra-band. The apparatus can configure a plurality of antenna arrays to serve the plurality of component carriers. The apparatus can transmit an output signal on the plurality of component carriers via the plurality of antenna arrays simultaneously.

Claims (23)

1 . A method, comprising:

determining, by an apparatus, a plurality of component carriers in a single frequency band, wherein each component carrier occupies a sub-band of the single frequency band;

configuring, by the apparatus, a plurality of antenna arrays to serve the plurality of component carriers based on corresponding maximum transmit power of each antenna array and a regulatory maximum transmit power for the single frequency band, wherein each of the plurality of antenna arrays comprises one or more power amplifiers such that an aggregate transmit power contributed by the plurality of antenna arrays for transmissions on the plurality of component carriers does not exceed the regulatory maximum transmit power; and

transmitting, by the apparatus, an output signal on the plurality of component carriers via the plurality of antenna arrays simultaneously.

2 . The method of claim 1 , wherein the single frequency band comprises an intra-band.

3 . The method of claim 1 , wherein one of the antenna arrays is configured to serve one of the component carriers.

4 . The method of claim 1 , wherein multiple antenna arrays are configured to serve one of the component carriers.

5 . The method of claim 1 , wherein one of the antenna arrays is configured to serve multiple component carriers.

6 . The method of claim 1 , wherein the antenna arrays are configured to transmit the output signal on a plurality of non-overlapped frequency ranges within the single frequency band.

7 . The method of claim 1 , wherein each of the antenna arrays are configured to transmit the output signal by an orthogonal frequency division multiplexing (OFDM) modulation.

8 . The method of claim 1 , wherein each of the antenna arrays are configured to transmit the output signal by a filter bank multi-carrier (FBMC) modulation.

9 . An apparatus comprising:

a processor that:

determines a plurality of component carriers in a single frequency band, wherein each component carrier occupies a sub-band of the single frequency band; configures a plurality of antenna arrays to serve the plurality of component carriers based on corresponding maximum transmit power of each antenna array and a regulatory maximum transmit power for the single frequency band, wherein each of the plurality of antenna arrays comprises one or more power amplifiers such that an aggregate transmit power contributed by the plurality of antenna arrays for transmissions on the plurality of component carriers does not exceed the regulatory maximum transmit power; and

a plurality of antenna arrays, each comprises one or more power amplifiers that:

transmit an output signal on the plurality of component carriers via the plurality of antenna arrays simultaneously.

10 . The apparatus of claim 9 , wherein the single frequency band comprises an intra-band.

11 . The apparatus of claim 9 , wherein the processor configures one of the antenna arrays to serve one of the component carriers.

12 . The apparatus of claim 9 , wherein the processor configures multiple antenna arrays to serve one of the component carriers.

13 . The apparatus of claim 9 , wherein the processor configures one of the antenna arrays to serve multiple component carriers.

14 . The apparatus of claim 9 , wherein the antenna arrays transmit the output signal on a plurality of non-overlapped sub-bands within the single frequency band.

15 . The apparatus of claim 9 , wherein each of the antenna arrays transmits the output signal by an orthogonal frequency division multiplexing (OFDM) modulation.

16 . The apparatus of claim 9 , wherein each of the antenna arrays transmits the output signal by a filter bank multi-carrier (FBMC) modulation.
