Abstract: Wireless network methods and apparatuses that may determine and provide, in real-time, the geographical locations of mobile stations of the wireless network are described herein. In one implementation, in order to determine the location of a mobile station (MS), the MS may obtain from a navigation service a decryption key to decrypt encrypted location information of multiple base station's (BS's) in its local area. The encrypted location information of the BS may then be decrypted and based at least in part on the recovered location information of the BS, determine the location of the MS. In another implementation, in order to determine and provide the location of an MS of a wireless network, a combination of location agents, location controller, and a location server may be employed to determine and provide the current location of the MS to requesting authorized clients.

Abstract: A system and method for multiplexing subchannels in an OFDMA network is provided. The subchannels can be multiplexed by splitting the subchannels in the frequency domain. Alternatively, the subchannels can be code division multiplexed using N orthogonal spreading codes. The subchannel multiplexing increases system capacity for low-rate services, such as voice-based services.

Abstract: A system and method for configuring component carriers in carrier aggregation is disclosed. The method comprises communicating a carrier aggregation capability for a selected UE to an enhanced Node B (eNode B) configured to provide service for a plurality of UEs. A plurality of component carriers at the eNode B can be configured for the selected UE based on the carrier aggregation capability of the selected UE. A component carrier configuration message is broadcast from the eNode B containing component carrier configuration information that is common to the plurality of UEs. Specific configuration information that is specific to the selected UE is communicated using dedicated communication signaling. Selected configured component carriers are then activated by the eNode B for the selected UE. Activation can be based on the UE's quality of service needs, bandwidth needs, and strength of signal for the component carriers.
