The invention provides a method for changing up and down TDD (Time Division Duplexing) configuration. The method comprises the steps that user equipment measures interference of user equipment in an adjacent cell to the user equipment and reports the interference situation to a base station, and the base station changes the current up and down TDD configuration according to the interference situation reported by the user equipment and the current up and down service requirements. The method meets the requirement of the dynamically changing up and down service load under the condition that the serious interference between the adjacent cells is not caused.

The invention discloses a method which aims at implementing capacity planning over different machine types to OLTP applications and includes: executing flexibility evaluation of the OLTP application to determine whether the OLTP application has flexibility problem; if the method determines that the OLTP application does not have flexibility problem, a performance comparison test is executed amongdifferent machine types to acquire the running performances of the different machine types; computing performance ratio among the different machine types according to the acquired running performances of the different machine types; acquiring the performance values of various machine types in different series, which is necessarily based on the performance ratios among different machine types acquired from the performance comparison test, and the acquired performance values are input into a parameter database for capacity planning, consequently a new parameter database for capacity planning isformed, and performance comparison and performance prediction can be implemented over different machine types; furthermore, the new parameter database for capacity planning can be used by a modeling method for capacity planning and a capacity planning tool to implement capacity planning over different machine types which aims at the OLTP application.

A time division duplex wireless communication system based on Code Spreading-Orthogonal Frequency Division Multiple Access (CS-OFDMA) and a smart antenna includes: an antenna array and multichannel transceiver, a space processor, a demodulator, an L2 processor and a modulator. The CS-OFDMA system provided by the present invention combines synchronous CDMA technique and OFDMA technique, overcomes the severe ISI caused by spectrum-spreading by the conventional CDMA system while transmitting wideband data, effectively counteracts frequency-selective fading and inter-cell interference, and is beneficial to reliable transmission of narrowband voice and wideband data and also beneficial to co-frequency networking.
