Abstract: A method and system to help facilitate efficient use of frequency spectrum. A base station will provide service on two carriers that partially overlap with each other in frequency. To facilitate this, the base station could shift the frame timing of one carrier in relation to the other carrier, so as to minimize or avoid overlap of the carriers' downlink control channels. Further, the base station could control service on each carrier in a manner that helps avoid resource conflicts within the overlapping frequency region.

Abstract: A base station of a radio access network (RAN) and a multiband mobile station are configured for wireless communication in a plurality of frequency bands. The RAN selects a configuration of uplink and downlink frequencies for a radio connection between the base station and multiband mobile station. The uplink and downlink frequencies in the selected configuration are in different frequency bands. The RAN may select a frequency band for the uplink frequency based, at least in part, on a distance between the multiband mobile station and the base station. That RAN may select a frequency band for the downlink frequency based, at least in part, on respective downlink loads at the base station for the first, second, and third frequency bands.

Abstract: When access nodes provide collocated service on overlapping carriers with different subcarrier spacing than each other, at least one of the access nodes could be configured to cluster its respective allocation of air-interface resources at an end of the frequency-overlap region, and a single guard band could then separate that clustered resource allocation from the remainder of the frequency-overlap region in which the other access node could allocate resources. In an example implementation for instance, the access nodes could be configured to cluster their respective concurrent allocation of resources at different respective ends of the frequency-overlap region so as to help maximize frequency width between transmission in the frequency-overlap region on one of the carriers with one subcarrier spacing and transmission in the frequency-overlap region on the other carrier with the other subcarrier spacing.
