Abstract: A beam plan that defines beams generated by a satellite that satisfy a set of communication service requirements is obtained. Fade condition information that indicates an amount of fade at particular geographic areas for one or more of the beams is obtained. A modification to the beam plan that mitigates the amount of fade at the particular geographic areas for the one or more of the beams is determined. The beam plan is modified based on the determined modification.

Abstract: A communication device detects sound with a microphone to produce a sound signal representative of the sound and searches the sound signal for unique inaudible sound signatures associated with a group identifier. Each sound signature identifies a respective communication device. Each sound signature is in an audible frequency band but masked to be imperceptible. If any of the sound signatures are determined to be present in the sound signal, the communication device selects one based on predetermined criteria associated with the group identifier.

Abstract: A subscription system includes a national subscription server capable of tracking which local stations subscribe to particular radio station music formats, for example AC middays, Top 40 afternoons, morning programs, or overnight Contemporary AC. A local music scheduler can query the subscription server for a log of nationally scheduled content to fill one or more dayparts of a local broadcast schedule. The subscription system can determine where to obtain the requested log, and provide the log to the local scheduler for insertion into a particular daypart of the local clock, while leaving the remaining dayparts free for local scheduling. Trusted subscribers can also be permitted to alter portions of log of nationally scheduled items. Inserting the log of nationally scheduled items into the local clock provides local awareness of both local and national media items scheduled for broadcast.

Abstract: The available transmission resources on a downlink-shared channel are divided into resource blocks, each resource block comprising a predetermined number of sub-carriers during a predetermined time period. The resource blocks are subdivided into localized resource blocks and distributed resource blocks. A user requiring sufficient resources can be allocated a plurality of said localized resource blocks. A user who would require only a small number of said localized resource blocks can instead be allocated summits of a plurality of said distributed resource blocks.

Abstract: Disclosed in the present invention are a method, an apparatus and a system for interference management. In the embodiments of the present invention, a Home NodeB (HNB) registers in a macro cell in advance, so that a NodeB Controller (NBC) knows the information of a potential interference source HNB beforehand.

The solution can avoid the situation in the prior art that the interference management is performed necessarily with a cell identity of the interference source HNB obtained by the terminal. With the application of the solution, the interference management to the HNB can be performed timely and effectively and the interference experienced by the terminal from the HNB is reduced.

Abstract: To effectively and efficiently provide control information, a broadcast pointer channel (BPCH) may be used to identify the type and perhaps relative location of control information that is being provided in a given frame structure, such as a sub-frame, frame, or superframe. A sub-frame (or like framing entity, such a frame or superframe) may have a BPCH and a corresponding system control information segment in which control information may reside. The system control information segment may have any number of control information blocks, wherein each control information block that is present may correspond to a particular type of control information. The BPCH is used to identify the type of control information that is present in a corresponding system control information segment, and if needed or desired, the relative locations of the various control information.
