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: Technologies and implementations for resource allocation for Voice over Internet Protocol are generally disclosed.

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 an LTE system, to maintain synchronization between different user equipment, a base station may consider one or more factors including the delay in transferring a timing advance command, an amount of time for the user equipment to process the timing advance command, and a period of time for repeated retransmissions of the timing advance command.

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: Technologies are generally described for methods and systems effective to provide an indication of a location of a first vehicle. In some examples, a processor may receive a request for the location of the first vehicle that includes an identification of the first vehicle. The processor may search for the identification of the first vehicle in a memory associated with a second vehicle. Based on a result of the search, the processor may retrieve location data relating to the location of the first vehicle. The processor may transform the location data into the indication of the location of the first vehicle.
