A METHOD FOR TRANSMITTING MULTI-WIRELESS-SCHEMES IQ DATA BETWEEN A BASIC BAND AND A RADIO FREQUENCY UNIT

摘要

A method for transmitting IQ data of a plurality of wireless schemes between a baseband unit and a remote radio unit is provided. The method comprises: dividing an IQ data area of a basic frame into a number of sub-channels; determining a mapping period for mapping IQ data of a wireless scheme to the basic frame and a synchronization period of the wireless scheme, and calculating the number Ni of sub-channels occupied by IQ data in a single carrier sector of the wireless scheme in each basic frame; for each of the plurality of wireless scheme, configuring the number Si of carrier sectors to be transmitted in a link and sub-channels to be occupied; and mapping IQ data of at least one of the plurality of wireless schemes to the sub-channels for transmission. The method allows IQ data of a wireless scheme mismatching with a basic frame structure to be transmitted between a baseband unit and a remote radio unit and IQ data of two or more wireless schemes to be transmitted simultaneously between the baseband unit and the remote radio unit.
