Apparatus and method for scheduling in carrier aggregated communication systems based on a transmit-receive-frequency gap band

An apparatus, comprising:

• at least one processor;
• non-transitory memory storing a program of instructions;
• wherein the non-transitory memory storing the program of instructions is configured to, with the at least one processor, configure the apparatus to at least:
• schedule allocation of physical downlink communication channels, at least one physical channel of the physical downlink communication channels being configured for downlink control to respective component carriers per time interval according to a communication service in which communication is performed on an aggregation of component carriers of one or more frequency bands such that component carriers to be used for transmission are separated from component carriers to be used for receiving by a transmit-receive-frequency gap band;
• exclude certain component carriers of the component carriers to be used for transmission from having allocated the at least one physical channel configured for downlink control;
• communicate, on a component carrier which is available, information that the excluded component carriers are not to be monitored;
• allocate a physical channel configured for shared uplink use to a component carrier of the component carriers to be used for receiving;
• allocate a physical channel configured for shared downlink use to a component carrier of the component carriers to be used for transmission;
• and
• allocate, for consecutive time intervals, the at least one physical channel configured for downlink control to available component carriers of the component carriers to be used for transmission,
• wherein not all of the available component carriers of the component carriers to be used for transmission are allocated in the same time interval with maximum transmission power, and
• wherein, in each time interval, the physical downlink communication channels to be allocated for transmission are allocated to the available component carriers of the component carriers to be used for transmission such that, in each frequency band, an overall emission spectrum does not reach beyond the transmit-receive-frequency gap band, so as to prevent any intermodulation interference associated with the overall emission spectrum from extending beyond the transmit-receive-frequency gap band.
