Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] figure 1 It is a schematic flowchart of a method for transmitting antenna port configuration information to user equipment in a base station according to an embodiment of the present invention.

[0033] Wherein, the method in this embodiment is mainly realized by a base station; wherein, the base station adopts a multi-dimensional antenna; preferably, the base station belongs to a 3D MIMO (Multiple-Input Multiple-Out-put, multiple input and output) system. Preferably, the network where the base station is located includes LTE-A or a subsequent upgraded network; more preferably, the base station includes an eNB (evolved Node B, evolved base station) in the LTE-A or subsequent upgraded network.

[0034] It should be noted that the base station is only an example, and other existing or future base stations that are applicable to the present invention sho...

Abstract

Provided is a method for transmitting antenna port configuration information to a user equipment in a base station. The base station adopts a multi-dimensional antenna. The method includes the following steps: a, acquiring antenna port configuration information of the base station, the antenna port configuration information being used for indicating configurations of the multi-dimensional antenna of the base station; and b, sending the antenna port configuration information to the user equipment on the basis of an RRC message. According to the solution of the present invention, the base station can send the antenna port configuration information to a specific user equipment in time via the RRC message, the complexity and the calculation amount during PMI searching through the user equipment are reduced, independent and more effective PMI searching can be realized, and the performance of the system is improved.
