Abstract: A wireless communication network locates User Equipment (UE) that is served by a wireless repeater chain. The wireless repeater chain wirelessly exchanges user data with the UE and wirelessly exchanges the user data with a wireless base station. The wireless base station determines an amount of communication time delay between the UE and the wireless base station over the wireless repeater chain. The wireless base station identifies the wireless repeater in the wireless repeater chain that is wirelessly attached to the UE based on the communication time delay. The wireless base station identifies the geographic location of the UE based on the geographic location of the identified wireless repeater. The wireless base station transfers the geographic location of the UE.

Abstract: An Orthogonal Frequency Division Multiplex (OFDM) data communication system comprises OFDM subsystems. A trusted OFDM subsystem receives trust challenge data and encodes the trust challenge data with a physically-embedded read-only trust key to generate encoded trust data. The trusted OFDM subsystem transfers the encoded trust data. The trusted OFDM subsystem receives user data into a trusted network receive buffer system and transfers a resource request to an access OFDM subsystem. The access OFDM subsystem receives the resource request and allocates and indicates trusted OFDM resource blocks to the trusted OFDM subsystem. The trusted OFDM subsystem schedules the user data using the trusted OFDM resource blocks and transfers the user data from the trusted network receive buffer system to a trusted Common Public Radio Interface (CPRI) transmit buffer system. The trusted OFDM subsystem transfers the user data from the trusted CPRI transmit buffer system to a CPRI communication system.

Abstract: A data communication system compresses packet headers. A transmitter executes state machines to process a data packet and determine if a transmitter state machine is transferring Interdependent Machine Output (IMO) data. The transmitter generates an IMO vector that indicates if any IMO data is in the data packet. If IMO is present, then the transmitter augments the IMO vector to indicate the individual transmitter state machines that transferred the IMO data. The transmitter transfers the data packet with the IMO vector to a receiver. The receiver processes the IMO vector to determine if any IMO data is transferred in the data packet. If IMO data is transferred, then the receiver processes the augmented IMO vector to transfer the IMO data to individual receiver state machine that correspond to the transmitter state machines that transferred the IMO data.

Abstract: Methods and systems are provided for enabling a base station to receive signals and synchronization information from neighboring base stations over a frequency band designated for transmissions to mobile devices. In embodiments, a cancellation signal is used to cancel antenna overload resulting from a base station's own transmission. By negating antenna overload, the base station may listen for synchronization signals output by neighboring base stations over the frequency band designated for transmission to mobile devices, such as a downlink band, for example. In embodiments, synchronization signals are used by the base station and/or a server to detect when synchronization failures occur at the base station and/or neighboring base stations. Synchronization signals from a neighboring base station may be used to re-synchronize a base station that have experience such a failure, in some embodiments.

Abstract: An Orthogonal Frequency Division Multiplex (OFDM) data communication system has an access subsystem that exchanges user data with an access network. The OFDM system has a trusted subsystem that exchanges user data with a trusted network. The trusted subsystem also encodes trust challenge data with a physically-embedded key and transfers the encoded trust challenge data for remote hardware trust validation. The access subsystem allocates OFDM resource blocks to the trusted subsystem and schedules its user data in the remaining OFDM resource blocks. The trusted subsystem schedules its user data in the allocated OFDM resource blocks and determines a Common Public Radio Interface (CPRI) sequence for the user data based on the OFDM scheduling. The access subsystem exchanges its user data with the trusted subsystem. The trusted subsystem exchanges the user data with a CPRI communication system based on the CPRI sequence.

Abstract: Methods and systems are provided for enabling a base station to listen and receive signals from neighboring base stations over a frequency designated for transmission to mobile devices for the detection of a synchronization failure. Embodiments provided herein enable the base station to cancel out its own transmission signal(s), which overloads the base station's own antenna 816 due to proximity. By cancelling out the base station's own signal, the base station listens and receives synchronization signals from one or more neighboring base stations over the frequency designated for transmission in a wireless communications network. A synchronization signal may be used, by the base station or as relayed to a server, to determine if the base station or the neighboring base station has experienced a synchronization failure.

Abstract: A Long-Term Evolution (LTE) communication system to facilitate updating network topology information when a mobile wireless repeater changes its attachment comprises a network topology server, a former macro LTE base station to which the mobile wireless repeater was previously attached, and a new macro LTE base station to which the mobile wireless repeater is presently attached. The network topology is server configured to receive updated attachment information transmitted from the mobile wireless repeater and transfer an attachment scan instruction for delivery to the former macro LTE base station and the new macro LTE base station. The former and new macro LTE base stations are configured to determine network attachment information for one or more network wireless repeaters and transfer the network attachment information for delivery to the network topology server. The network topology server is further configured to receive the network attachment information and update a network topology map.
