1. A mobile communication base station for joint sensing and communication, the mobile communication base station comprising:
a baseband processor configurable to transmit and receive sensing and communication signals via one or more channels and further configurable in one or more of a communications-transmit mode, a communications-receive mode, a sense-transmit mode and a sense-receive mode, the baseband processor comprising, for each of the one or more channels:
a carrier mapping-demapping module configured to:
(i) in the communications-transmit mode and the sense-transmit mode, receive a plurality of transmit-OFDM-symbols, map the transmit-OFDM-symbols to a sub-carrier and output a plurality of mapped-transmit-OFDM-symbols, and
(ii) in the communications-receive mode, receive a plurality of mapped-receive-OFDM-symbols, de-map the mapped-receive-OFDM-symbols and output a plurality of receive-OFDM-symbols;
a sense module configured in the sense-receive mode to compare the plurality of mapped-receive-OFDM-symbols with the plurality of transmit-OFDM-symbols from the same channel or a different channel; and determine at least one of a range, velocity, and angle-of-arrival of a sensed object from the comparison; and
wherein the baseband processor further comprises:
a controller coupled to the carrier mapping-demapping module of the one or more channels and configured to control the carrier mapping-demapping module of the one or more channels to:
map the plurality of transmit-OFDM-symbols to a bandwidth part of an available OFDM bandwidth in the sense-transmit mode and the communications-transmit mode.
