The wireless communication method comprises reporting, to a wireless network node, at least one precoding matrix group of at least one codeword according to a transmission mode, receiving, from the wireless network node, at least one codeword, and performing a transmission based on power ratio of the codeword.
1 . A wireless communication method for a wireless terminal, comprising:
reporting, to a wireless network node, at least one precoding matrix group of at least one codeword according to a transmission mode;
receiving, from the wireless network node, at least one codeword which is reported by the wireless terminal; and
performing a transmission based on power ratio of one of the at least one codeword.
2 . The wireless communication method of claim 1 , wherein the number of antenna ports configured for the transmission or the number of antenna ports configured for sounding reference signal, SRS, resources of the transmission is 4.
3 . The wireless communication method of claim 1 , wherein a coherent capability of antenna ports configured for the transmission is non-coherent or partial-coherent.
4 . The wireless communication method of claim 1 , wherein a codeword is a precoder or a precoding matrix.
5 . The wireless communication method of claim 1 , wherein the at least one precoding matrix group is transmitted by transmitting at least one transmitted precoding matrix indicator (TPMI) group corresponding to the at least one precoding matrix group.
6 . The wireless communication method of claim 1 , wherein each of the at least one precoding matrix group consists of at least one basic TPMI group,
