<p>The invention discloses a wireless transmission method of using efficient high performance frame structure in wideband TDD system, including: one subframe of fixed time is divided into N+1 basic time slots and three special time slots, wherein one basic time slot is utilized for transferring cell broadcast or call information, and N basic time slots are utilized for up-transferring and down-transferring the service information; when it is required to raise data transmission capability of signal time slot , some basic time slots of N basic time slots are merged into one extended time slots , and the extended time slots are utilized for transferring high rate service corresponding to the length of the extended time slots. The invention provides a developing direction of TDD system beyond 3G, and uses the frame structure to complete the wireless transmission. It can provide the service of different data rates only by changing the length of the basic time slots, making the basic time slots merged into the extended time slots of different times and using different modulation modes and spread frequency coefficients. When the system bandwidth is 5, 10 and 20MHz separately, and at the same time the invention can satisfy the need of data transmission capability of each rate in 100Mbps.</p> |
