1. A method of wireless communication, comprising:
reporting first indication information to a network device through radio resource control (RRC) signaling, wherein the first indication information indicates a first transmitted precoding matrix indicator (TPMI) group, and the first TPMI group is a TPMI group in a TPMI group set;
receiving a first TPMI indicated by the network device; and
reporting second indication information to the network device, wherein the second indication information indicates, through a bitmap, whether a corresponding precoding matrix supports full power transmission by a terminal device upon 2-port transmission,
wherein the TPMI group set comprises at least eight TPMI groups,
wherein the at least eight TPMI groups comprise seven basic TPMI groups and at least one newly added TPMI group,
wherein the newly added TPMI group is obtained based on part or all of elements in the seven basic TPMI groups,
wherein the TPMI group in the TPMI group set comprises part of the seven basic TPMI groups and at least one newly added TPMI group, and
wherein the newly added TPMI group is obtained based on part or all of elements in the seven basic TPMI groups.
