摘要： A method for wireless network communication is provided. The method comprises determining, by a transmitter including a quantity of antennas, a quantity of transmitted layers; mapping a quantity of data symbols to the antennas using a quantity of precoders; generating a quantity of demodulation reference signal (DMRS) antenna ports based on the quantities of the antennas, the transmitted layers, and the precoders; and determining whether to precode at least one of the DMRS antenna ports with the precoders. The method further maps the precoded data symbols and the DMRS antenna ports to a quantity of resource elements. The method then modulates a signal comprising the resource elements and transmits the modulated signal to a receiver. Subsequently, the method estimates a channel received by the receiver over the DMRS antenna ports.

摘要： A method, a codebook, and a Base Station (BS) for precoding are provided. The precoding method includes: obtaining a total uplink power of a User Equipment (UE); if the total uplink power is greater than ¾ of a rated total transmit power of antennas, selecting a codeword from a first codebook with imbalanced power between layers; otherwise, selecting a codeword from the first codebook and a second codebook with balanced power between layers, so as for precoding data to be transmitted according to the selected codeword. Thus, a loss of an antenna performance at a high signal-to-noise ratio is reduced, and the loss of the power amplification of the antenna is reduced if the transmit power of the antenna is restricted.
