Embodiment Construction

[0030] In view of the fact that in the existing NGB-W system, due to the uneven distribution of the number of unit words in each time sub-slice, time slicing and resource mapping still need to be performed, the inventors of the present invention have improved the existing technology , a method for time slicing and resource mapping of data in type 2 physical layer pipes in the NGB-W system is proposed, which can successfully complete all type 2 physical layer pipes corresponding to the current NGB-W frame Time slicing of data and resource mapping of data in all type 2 physical layer pipes in the current NGB-W frame. Compared with the prior art, the invention can effectively improve the flexibility of the NGB-W system of the next generation broadcasting and television wireless network to implement time slicing and resource mapping of data units carried by type 2 physical layer pipes.

Abstract

The present invention provides a method for time slicing and resource mapping of type 2 physical layer pipeline data in the next-generation broadcast television wireless network NGB-W system, which is characterized in that it includes: The unit words in the type 2 physical layer pipeline are mapped to multiple time sub-slices in the current NGB-W frame, and complete the time slicing of data in all type 2 physical layer pipelines corresponding to the current NGB-W frame; Map unit words in all type 2 physical layer pipes in the current NGB‑W frame to OFDM data bearing units, and complete resource mapping of data in all type 2 physical layer pipes in the current NGB‑W frame. Compared with the prior art, the time slicing and resource mapping method of the present invention can realize that after time interleaving, type 2 physical layer pipelines are mapped to the corresponding frame in the case where the number of unit words cannot be divisible by the number of time sub-slices, Perform time slicing and resource mapping on the data of type 2 physical layer pipelines.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for performing time slicing and resource mapping on data units carried by type 2 physical layer pipes in a next-generation radio and television wireless network system. Background technique [0002] Next Generation Broadcasting networks-Wireless (NGB-W) is an integral part of the next-generation broadcasting network. proposed for development. The NGB-W system realizes the integration of broadcasting and two-way communication networks, and is currently a hot topic in the communication industry. Because of its technical rationality and broad market prospects, it has attracted extensive attention from academia and industry. [0003] In the NGB-W system, in order to realize multi-service transmission, the NGB-W standard considers introducing the PLP (Physical Layer Pipes, physical layer pipe) technology adopted by the DVB-T2 standard when realizing multi-service transmis...
