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.

Abstract: Mitigating interference in such potential interference areas of a wireless communication network includes determining that a first sector associated with a first wireless air interface and configured with a first subcarrier spacing is facing a second sector associated with a second wireless air interface and configured with a second subcarrier spacing, wherein the first and second subcarrier spacings are different, and assigning resources towards the second sector in a different order than resources assigned to the first sector.

Abstract: Disclosed are methods and systems for selecting and configuring a distribution of multiple-input multiple-output (MIMO) layers among one or more carriers. For a first candidate distribution, a base station may determine a first total throughput of communications between the base station and a user equipment device (UE). And for a second candidate distribution, the base station may determine a second total throughput of communications between the base station and the UE. Then, the base station may determine that the first total throughput is higher than the second total throughput and may responsively configure MIMO service of the UE with MIMO communication on at least two layers distributed across one or more carriers in accordance with the first distribution.

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 database is maintained that maps source cell regions to channel condition on the neighbor cell(s) coverage. The database also tracks whether the neighbor cell has better, weaker, or similar signal strength than the source cell. The channel condition and bitrate requirement of each wireless device being served by the source cell are also tracked. Once a particular neighbor cell has been selected for traffic offload (i.e., handover of one or more wireless devices), the source cell uses the database to select which wireless devices should send measurement reports. Those wireless devices with channel conditions that are mapped in the database to the target cell's coverage are designated for possible selection. Among these wireless devices, either the wireless devices with the highest or lowest bitrate requirements are selected to provide measurement reports for the target cell.
