Abstract
In a multi-standard base station (BS) site, a first (BS) module operates in multi-antenna transmission mode according to a first radio access technology (RAT) by means of multiple transmitter branches. The first BS module determines phase/time compensation information based on UE feedback information representative of precoding matrix index, PMI. The multi-standard BS site performs, for operation according to the first RAT, a first compensation for a relative phase/time error between at least two of the transmitter branches based on the phase/time compensation information. A second BS module operates for transmission according to a second RAT by means of at least two of the multiple transmitter branches. The multi-standard BS site performs, for operation according to the second RAT, a second compensation for a relative phase/time error between at least two of the transmitter branches based on the phase/time compensation information from the first BS module.
