Abstract: A system and method for supporting multicast and broadcast service (MBS) on one or more separate carrier frequencies are provided. The system includes carrier frequency information to indicate that data in an MBS zone resides on a separate carrier, and to direct the subscriber stations to receive MBS data on the separate carrier. The method comprises establishing an MBS MAC connection between a subscriber station and a base station in a MBS zone, processing carrier frequency information to determine whether data associated with the MBS zone resides on a separate carrier, and if so, transmitting the MBS data on the separate carrier.

Abstract: A method for providing a multicast and broadcast service (MBS) in a wireless network, the method comprising: establishing an MBS MAC connection between a mobile station (MS) and a first base station (BS) in an MBS zone; sending a first MBS_MAP message in a first frame, wherein the first MBS_MAP message includes information for locating a second MBS_MAP message in a second frame, but does not specify the location of the second MBS MAP message within the second frame; and sending the second MBS_MAP message in the second frame.

Abstract: The present invention provides a scheduling technique that allows individual nodes in a wireless communication network to independently determine their own communication schedules. The communication nodes in the wireless communication network are associated with one or more compatible communication nodes through substantially non-contending communication links, wherein the communication links within a group of compatible communication nodes are substantially non-interfering. Each node will exchange scheduling information with the various compatible communication nodes, and determine the communication schedule for future communications with those compatible communication nodes. This communication schedule may dictate when information is received from or sent to a compatible communication node during a given transmission opportunity.

Abstract: Protected memory locations or contents are associated with respective corresponding keys. Memory operations that alter the protected memory locations or contents are denied unless the corresponding keys are provided. In one implementation, the keys are stored in a key store on an electronic device and accessible only to a memory access manager that controls access to the protected memory and contents. In order to alter a protected memory location or contents, an electronic device component must first obtain the required key or keys from another source, such as a source from which data to be written to a protected memory location is received, and then provide the or each key to the memory access manager. After a memory operation has been permitted or completed, any keys provided to the memory access manager by an electronic device component are rendered inaccessible, such as by deleting the keys from memory.

Abstract: A high speed Advanced Programmable Interrupt Controller (APIC) system includes a plurality of local units for prioritizing and passing interrupts, an Input/Output (I/O) unit for feeding interrupts to the local units, and a serial link data transmission system for interconnecting the I/O unit and the local units. The I/O unit and each local unit have a parallel I/O interface.
