Abstract: A new access channel protocol for use in cellular systems such as CDMA whereby the data transfer efficiency of an access message is increased by removing the requirement that a preamble frame and a message capsule frame have equal times of duration. With such removal, the BTS must inform listening MSs as to the time duration of the frames in each of the preamble and the message portions of the access channel time slot in addition to previously supplied information as to the number of frames in each portion. When unequal frame duration times are allowed, each portion of the access channel may be more nearly optimized to the actual time required to perform the functions of synchronization and message detection.

Abstract: A system and method that codes and interleaves data onto separate channels for transmission in a wireless multicarrier system. The multicarrier wireless transmission system has an input terminal for receiving a plurality of user data bits. The system adds error-correcting bits to the user data bits. The system then arranges and stores the combination of error-correcting bits, collectively coded symbols, in a two dimensional matrix. The system arranges the coded symbols by writing them into the matrix according to columns, from left to right. The system then retrieves the symbols from the matrix according to rows, from top to bottom. The system then transmits the retrieved symbols on different carrier frequencies such that consecutive symbols are each transmitted on a different carrier frequency.

Abstract: A synchronous discontinuous transmission medium access control (SDTX-MAC) method and apparatus for more efficiently using existing uplink channels by sharing these uplink channels between multiple terminals engaged in bursty data transmission. This is accomplished by assigning each mobile terminal an individual time slot and by not requiring each mobile terminal to broadcast its identity. This results in a reduction in the number of receivers on each base station and a reduction in the length of the synchronization message.

Abstract: The User Equipment (UE) initiates initial access by transmitting an uplink reference signal on at least one UE beam. Each Base Station (BS) carries out a spatial search of any detected uplink reference signals, estimates the Angle of Arrival (AoA) of the uplink reference signals, forms a dedicated downlink beam pointed toward the UE at the estimated AoA, and sends an acknowledgement for the uplink reference signal on the dedicated downlink beam. The UE carries out a spatial search of the received acknowledgement, and identifies the UE beam angular pointing position, from which receives the acknowledgement with the highest signal quality, as the UE beam boresight toward the BS. The UE sends a connection setup request message to the BS on the identified UE beam boresight. The uplink reference signals and acknowledgements may comprise of only a single preamble, effectively carrying one bit of information, or carry a small payload.

Abstract: A hybrid satellite-mesh network including a ground segment, a mobile segment and a satellite segment provides high bandwidth communication between mobile platforms and the Internet. The satellite segment is used only when mesh network communication links between mobile segment nodes and ground segment nodes are unavailable. Mobile segment nodes can function in either an access terminal mode or an access point mode to communicate with other mobile segment nodes according to a routing algorithm in a mesh portion of the network. Mobile segment nodes employ adaptive frequency reuse, link level date rate adaptation, link level power control and adaptive beam forming antennas.

Abstract: A method for air to ground communication interference mitigation within an aircraft equipped with a multi-beam array antenna includes adjusting a modulation symbol interleaving and/or forward error correction of an aircraft receiver interface in response to detected interference from an interferer. The method further includes reducing a data rate of the aircraft receiver interface when the adjusting of the modulation symbol interleaving and/or forward error correction does not mitigate the detected interference. Another method for interference mitigation may include performing antenna beam-steering away from a geographic (GEO) arc during an aircraft turn. This method further includes reducing an aircraft transmitter transmit power when a signal quality of a forward link is within a predetermined range of a signal quality threshold.

Abstract: Reverse link data rate indications in wireless communication systems are defined with low identification overhead. Existence of a pilot signal is leveraged in order to reduce the overhead for identifying and selecting the reverse link data rate. At least two distinguishable pilot signals are defined, in which, based on the particular pilot signal present in the transmitted frame, at least one rate set from the multiple available rate sets can be determined. Reverse rate information in the transmitted frame is then used to identify which specific data rate within the determined rate set is used. Based on the identified data rate, the receiver may then decode the payload data in the transmitted frame.
