Abstract: A quantity of antennas included in the antenna assembly is greater than a quantity of receive antennas supported by customer premises equipment (CPE). Therefore, when a network changes, the CPE may select, from a plurality of antennas included in the antenna assembly, a quantity of antennas with relatively good data transmission performance as receive antennas, where the quantity is the same as the quantity of receive antennas supported by the CPE. That is, the CPE may not need to adjust directions of antennas, but select, from a redundant quantity of set antennas, antennas with relatively good receiving performance to ensure that the CPE is aligned with a direction with relatively good signal quality.

Abstract: The present invention provides a data transmission method, a remote radio unit RRU, and a baseband unit BBU. The method includes: receiving, by the RRU, stream data sent by the BBU, where the stream data is obtained after the BBU performs resource mapping processing on to-be-transmitted downlink data; performing, by the RRU, stream to antenna mapping processing on the stream data; and sending, by the RRU, mapping-processed data to user equipment by using an antenna. In the data transmission method of embodiments of the present invention, service stream data is transmitted between the BBU and the RRU. This can reduce data traffic between the BBU and the RRU, so as to reduce fronthaul data bandwidth between the BBU and the RRU.
