摘要： A cellular communication system includes base stations supporting macro cells and with unique cell scrambling codes within a region. The system further includes access points supporting underlay cells and with shared cell scrambling codes within the region. One or more of the access points or base stations comprise transmit means for transmitting an indication of at least a first shared scrambling code to a remote station. The shared scrambling code is shared by a plurality of access points. The remote station is arranged to receive the first shared scrambling code and to determine if a first signal using the first shared scrambling code is received. If the first signal is detected, a handover controller initiates a handover of the remote station to at least a first access point of the plurality of access points sharing the first shared scrambling code.

摘要： A cellular communication system comprises an access point (101) which supports an underlay cell of a first cell on an underlay frequency using another frequency. A proximity detector (113) detects user equipment (109) in response to a wireless transmission therefrom, which uses a different transmission technology from a transmission of the cellular communication system. In response to the proximity detection, the access point (101) temporarily transmits a pilot signal on the first cell frequency. The user equipment (109) is then switched to the access point (109) and the underlay frequency in response to a detection indication from the user equipment (109) indicating that the pilot signal has been detected. Following the switch the access point (101) terminates the transmission of the pilot signal.

摘要： A network for a cellular communication system comprises access points (105-109) supporting cells within a region (113). Each access point (105-109) has an individual proxy address of a proxy address space which is a local address space of an address proxy (101) and a common network address of a network address space which is a network wide address space. A gateway access point (103) covers an entry point to the region (113) and detects a remote station entering the region. It then determines an access point (105) in the region to which the remote station is handed over and transmits a binding message to the address proxy (101) with an indication of the access point (105). In response to receiving the binding message, the address proxy (101) establishes a binding between the common network address and the proxy address of the access point (105). Data for the remote station is then forwarded to the access point (105) using the binding.

摘要： A random intrinsic chip ID generation employs a retention fail signature. A 1st and 2nd ID are generated using testing settings with a 1st setting more restrictive than the 2nd, creating more fails in the 1st ID bit string that includes 2nd ID bit string. A retention pause time controls the number of retention fails, adjusted by a BIST engine, wherein the fail numbers satisfy a predetermined fail target. Verification confirms whether the 1st ID includes the 2nd ID bit string, the ID being the one used for authentication. Authentication is enabled by a 3rd ID with intermediate condition such that 1st ID includes 3rd ID bit string and 3rd ID includes 2nd ID bit string. The intermediate condition includes a guard-band to eliminate bit instability problem near the 1st and 2nd ID boundary. The intermediate condition is changed at each ID read operation, resulting in a more secure identification.

摘要： A structure and method for forming isolation and a buried plate for a trench capacitor is disclosed. Embodiments of the structure comprise an epitaxial layer serving as the buried plate, and a bounded deep trench isolation area serving to isolate one or more deep trench structures. Embodiments of the method comprise angular implanting of the deep trench isolation area to form a P region at the base of the deep trench isolation area that serves as an anti-punch through implant.
