LOCAL AND GLOBAL TRANSMISSION IN WIRELESS BROADCAST NETWORKS Russian patent published in 2008 - IPC H04H20/00 

FIELD: communications.

SUBSTANCE: in different types of broadcasts, with different levels of coverage in a wireless broadcast network, each base station processes data for global transmission in accordance with the first mode (or coding and modulation scheme) for generating data symbols for global transmission and processes data for local transmission in accordance with the second mode for generating data symbols for local transmission. The first and second modes are selected based on the desired coverage for the global and local transmission, respectively. The base station also generates control signals and additional service information for local and global transmission. Data, control signals and additional service information for local and global transmission are multiplexed in their transmission intervals, which can be different sets of frequency sub-ranges, time segments or different groups of sub-ranges in different time segments. More than two types of transmissions can also be multiplexed and transmitted.

EFFECT: design of a wireless broadcast network, which can efficiently transmit different types of information with various fields of coverage.
