Abstract: A precoding processing method and user equipment are disclosed. The precoding processing method includes: selecting a codebook vector for performing precoding processing for data among a codebook set of Nt antennas, where the codebook set includes a first codebook vector   [ A B ] of a uniform linear array and a second codebook vector   [ A - B ] generated according to the first codebook vector, where A is a (Nt/2)×1 vector composed of a first half of elements of the first codebook vector, B is a (Nt/2)×1 vector composed of a last half of elements of the first codebook vector, and Nt is a positive even number; and sending an index number of the codebook vector to a base station, whereupon the base station uses the codebook vector corresponding to the index number to perform precoding processing for the data to be transmitted by the antennas. Embodiments of the present invention make the codebook set compatible with two types of antenna configuration modes.

Abstract: In a control channel resource transmission method, user equipment (UE) obtains a configuration parameter in a candidate control channel set according to a preset protocol and/or higher-layer signaling sent by a base station, where the higher-layer signaling is used to notify the configuration parameter. The UE determines an antenna port according to the obtained configuration parameter, and then receives, through the antenna port, a control channel or a control channel element sent by the base station. The base station determines the antenna port according to the same configuration parameter as that of the user equipment, and sends, by using the antenna port, the control channel or the control channel element to the user equipment.
