Abstract: Provided are apparatuses and methods for detecting neighboring cells in a communication network based on Transmission Parameter Signaling (TPS) bits received in a signaling frame. In one example, a signaling frame contains a field of TPS bits that indicate a type of the signaling frame. The type of the signaling frame may indicate the information carried in the signaling frame as information of a current cell or a neighboring cell. The signaling frame may further include information from a neighboring cell in the same network or a different network as the current cell. The signaling frame may further be arranged in a superframe in which the a plurality of frames are transmitted to a receiver in a certain sequence. Each frame in a superframe or a sequence of frames may include a parameter for defining the location of the frame.

Abstract: Embodiments are directed to defining hierarchical digital broadcast transport streams as separate cells, which reduces the signaling in OSI layer 1, and removing use of sub-cells so that the coverage area of a transposer may be treated as a cell. In accordance with at least one embodiment, each hierarchical DVB-H stream (i.e., the HP stream and the LP stream) has its own separate dedicated “current signal” frame. This allows the streams to be independent of each other (even to belong to different networks). Furthermore, in accordance with the hierarchical signal arrangement, a cell can be uniquely identified by its network_id and cell_id. In accordance with at least one embodiment, frequency may be used as an additional identifier thereby allowing a first cell to be transposed to a sub-cell.

A cellular transmitter is operated in an apparatus. In the same apparatus, the digital broadband broadcast transmission transmitted by the digital broadband broadcast transmitter is received, and the received digital broadband broadcast transmission is time deinterleaved.

The apparatus further includes a controller configured to disregard a signal in response to determining that the signal does not carry time-sliced elementary streams.

Abstract: Services and service components in a broadcast network may be mapped to disparate physical layer transmission channels (PLPs) using logical layer pipes (LLPs). The use of LLPs allows different service components of a single service to be mapped to physical layer transmission channels (PLPs). Accordingly, service components may be shared among different services. Additionally or alternatively, different functions (e.g., different error detection or correction protocols) may be applied to each service components of a service. A receiver may identify services, service components and corresponding PLPs based on LLP identifiers. The receiver may then access and receive desired services and service components through the identified PLPs.

Abstract: A system and method for dynamically dividing the capacity of a fixed time division multiplexing (TDM) frame between physical channels for data transmission. According to various embodiments, a time frequency frame is divided into a plurality of subframes, and each of the plurality of subframes are divided into a plurality of corresponding slots. The plurality of slots are then selectively time shifted such that a defined time shift exists between corresponding slots in each subframe within the time frequency frame. For any slots or slot portions which have been selectively shifted beyond the end of the time frequency frame, such slots or slot portions are cyclically shifted to the beginning of the frame. Service data is then written into the slots of the time frequency frame, and the frame containing the service data can then be transmitted. Initialization and service access processes for a receiver are also provided.
