Abstract:
Various embodiments of a scheme of dynamic activation and release of carrier aggregation in an LTE-Advanced system are provided. When transmission need of an LTE-Advanced user is large and the user is within coverage of at least one secondary component carrier, carrier aggregation is activated while a certain amount of resource of each component carrier is preserved to support carrier aggregation. This avoids unnecessary activation and waste due to signaling cost. When the primary component carrier of an LTE-Advanced user has sufficient resource to satisfy transmission need of the user or when the user is not within coverage of at least one secondary component carrier, carrier aggregation is released. This minimizes complex measurement and cost of controlling signals due to multi-carrier scheduling.
Abstract:
Techniques generally described are related to a method to adjust data transmission from a core network to a base station. The method may include measuring, by the base station, a first air-interface data rate for transmission of mobile data to a mobile device during a first transmission period. The method may include estimating, by the base station based on the first air-interface data rate, a second air-interface data rate for transmission of the mobile data to the mobile device during a second transmission period subsequent to the first transmission period. The method may further include generating, by the base station, a first threshold and a second threshold for a cache based on the second air-interface data rate.
Abstract:
In an example embodiment, one or more scheduler of base stations may be configured to schedule resource blocks on a frequency band of two adjacent cells to eliminate crossed timeslots interference by selecting different starting points on the frequency band.

Abstract:
Frequency spectrum resources available to a node of a wireless communication network may be allocated for either an uplink or downlink channel by a scheduler module. The scheduler module may schedule a specific frequency spectrum resource based at least in part on whether the frequency spectrum resource has been assigned to a downlink resource pool, an uplink resource pool, or a shared resource pool. Assignment of frequency spectrum resources to the downlink resource pool, the uplink resource pool, or the shared resource pool may be based on suitability of each frequency spectrum resource for uplink channel or downlink channel.

Abstract:
In a heterogeneous cellular communication network, a macro cell equipped with a base station may be configured to support one or more macro user equipment (UE) and one or more micro cells, each of which further serves as proxies of one or more micro UE for wireless communications between the micro UE and the macro cell. The base station may be configured to assign a first cell ID to the macro cell and other cell IDs that have a mathematical distinction from the first cell ID to the micro cells.
