Abstract

The invention provides a resource allocation method and system based on the Next Generation Broadcasting-Wireless (NGB-W). The method comprises the following steps: selecting the fast Fourier transformation (FFT) and a cyclic prefix (CP); selecting a scattered pilot type of data symbols according to the FFT and the CP; utilizing the number of OFDM symbols and the number of effective subcarriers to indicate structural parameters of NGB-W multiplex frames; allocating resources for signaling according to construction results; when the resource allocation for the signaling is completed, allocating resources for transfer channels (TCHs) according to the construction results; when the resource allocation for the TCHs is completed, allocating resources for filled fields according to the construction results; and when the resource allocation for the filled fields is completed, returning to the step of resource allocation for the signaling, so as to enter a next turn of resource allocation. The method and system provided by the invention can flexibly achieve data multiplexing and resource allocation based on the NGB-W.

Description

technical field [0001] The present invention relates to the field of wireless broadcasting systems, in particular to a resource allocation method and system based on next-generation wireless broadcasting. Background technique [0002] With the development of new broadcast streaming media technology, the real-time data traffic carried by the wireless broadcast transmission channel is getting higher and higher, and has the technical characteristics of high throughput, high concurrency, and low delay; Transmission QOS also proposes different requirements. [0003] The existing domestic wireless broadcasting systems such as DTMB and CMMB are gradually unable to adapt to the development of new media technology, so the NGB_W standard and system to meet the needs of "triple play" began to be jointly formulated by domestic scientific research institutes, universities and other organizations, in order to meet the new requirements Due to the characteristics of wireless air interface ...
