Abstract

This invention discloses a method for signal emitting and receiving based on time-division duplex, setting many antennas at the basestation side and mobile station side separately, the said antennas are designed on the principle that noises received on each antenna are mutual independent, thus, the mobile station measures received signals on its own side receive antennas and selects one as the up-line emitting antenna to take it as the emitting antenna at the next up-line emitting time. The base station selects one antenna as the downstream emitting antenna from multiantenna at its side receiving signals from the mobile stations and emits signals to the mobile at the next time, increasing transmission efficiency of high speed data and getting the maximum high S / N ratio.

Description

technical field

[0001] The present invention relates to signal transmission and reception methods in a wireless communication system. Background technique

[0002] Wireless communication provides the means for people to connect with each other and obtain information anytime and anywhere, so it has been rapidly popularized in recent years. However, in the current wireless environment, due to the requirement of mobility, the directional transmission of wireless signals has certain limitations, which inevitably causes mutual interference between wireless communications of different users. In order to ensure the normal progress of various wireless communications, the use of wireless spectrum is generally subject to strict restrictions and management. In this way, wireless communication cannot have a large bandwidth like wired communication. Therefore, based on the limited available wireless spectrum, how can Increasing the information transmission capability of the wireless com...
