摘要： PROBLEM TO BE SOLVED: To provide techniques to seamlessly switch reception between multimedia programs and stream. SOLUTION: For continued decoding, a wireless device continues to receive, decode, decompress and display a current program, even after a new program has been selected, until overhead information needed to decode the new program is received. After receiving the overhead information, the wireless device decodes the new program but continues to decompress the current program. The wireless device decompresses the new program after decoding this program. For early decoding, the wireless device receives a user input and identifies a program with potential for user selection. The wireless device initiates decoding of the identified program, prior to the selection of the identified program, so that the identified program can be decompressed and displayed earlier if it is subsequently selected.

摘要： PROBLEM TO BE SOLVED: To provide a technique for transmitting variable transmission in a wireless communication system. SOLUTION: Physical channels to be sent in a super-frame are identified and allocated to time slots in the super-frame. The coding and modulation for each physical channel are selected based on its capacity. The data for each physical channel is selectively encoded based on an outer code rate, e.g., for a Reed-Solomon code, and further encoded based on an inner code rate, e.g., for a Turbo code. The encoded data for each physical channel is mapped to modulation symbols based on a selected modulation scheme. The modulation symbols for each physical channel are further processed (e.g., OFDM modulated) and multiplexed onto the time slots allocated to the physical channel. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method for performing local transmission and wide area transmission in a wireless broadcast communication network. SOLUTION: In order to perform broadcast communications of transmission of different type having a hierarchy with different communication-possible range in a wireless broadcast communication network, each base station processes data for the wide area transmission according to a first mode (or coding scheme and modulation scheme) (S812), and processes data for the local transmission according to a second mode (S813). Based on each desired communication-possible range for the wide area transmission and the local transmission, each of the first mode and the second mode is selected. In the same way, each base station multiplexes the data for the local transmission with the data for the wide area transmission without overlapping partially, and carries out broadcast communication for the multiplexed data.

摘要： PROBLEM TO BE SOLVED: To facilitate the efficient reception of each data stream by transmitting overhead information. SOLUTION: A base station transmits many data streams on many data channels (MLC). The MLCs are transmitted at different times and on different frequency sub-bands. The overhead information represents a time-frequency position of each MLC, and is sent as "composite" overhead information and "embedded" overhead information. The composite overhead information represents the time-frequency positions of all the MLCs and is periodically sent in each superframe. A radio device receives the composite overhead information, determines the time-frequency position of each MLC and receives each MLC at the represented time-frequency position. The embedded overhead information of each MLC represents the time-frequency position of an MLC in the next superframe and is transmitted together with a payload of the MLC in the current superframe.

摘要： PROBLEM TO BE SOLVED: To provide a system and method for modulation diversity. SOLUTION: The system and method for modulation diversity uses interleaving. Code bits are placed into groups and are then shuffled within each group. An interleaver uses a bit-interleaver solely to achieve m-ary modulation diversity and uses a two-dimension interleaved interlace table and a run-time slot-to-interlace mapping to achieve frequency diversity which provides better interleaving performance without the need for explicit symbol interleaving.
