摘要：
The present invention relates to a method for downlink common pilot configuration for a base station serving a first set of User Equipments UEs and a second set of UEs, wherein the first set of UEs consists of 4-branch MIMO capable UEs and the second set of UEs consists of 4-branch MIMO mode incapable UEs, The method comprises the steps of determining (S410) information related to the UEs served by the Base Station BS; and configuring (S420) transmission of at least one common pilot from the BS to the served UEs based on the determined UE related information.In an example 4-branch MIMO system, at most 4 common pilots are configurable to be transmitted, and the at least one common pilot is two common pilots newly introduced into a legacy system. The present invention also relates to a base station configured for performing the method for downlink common pilot configuration and a computer readable storage medium. (Figure 4b)
