Abstract

The invention discloses a signaling field of a wireless MIMO communication system. The signaling field comprises a scrambling code initializing subfield for allocating the scrambling code state, a single carrier/orthogonal frequency-division multiplexing subfield for finishing single carrier and orthogonal frequency-division multiplexing transmission, a dynamic bandwidth allocation subfield, a spatial flow allocation subfield and a length subfield for allocating the length of sent data. The invention further provides a frame structure based on the signaling field and a wireless MIMO communication method with the frame structure adopted. The dynamic bandwidth is achieved more easily, and the spectral efficiency is effectively improved. By means of the signaling field and the communication method of the wireless MIMO communication system, multi-user and multi-flow allocation and allocation of a plurality of carrier sending modes are achieved more effectively.

Description
