Signaling of power information for mimo transmission in a wireless communication system

A method for wireless communication, comprising:

• determining power information indicative of total power for a designated number of channelization codes with equal power per channelization code;
• and
• sending the power information to a user equipment (UE).

An apparatus for wireless communication, comprising:

• means for determining power information indicative of total power for a designated number of channelization codes with equal power per channelization code;
• and
• means for sending the power information to a user equipment (UE).

An apparatus for wireless communication, comprising:

• at least one processor configured to determine a power offset indicative of total power for a set of 15 orthogonal variable spreading factor (OVSF) codes, regardless of number of available OVSF codes, with equal power per OVSF code, and to send the power offset in a Radio Resource Control (RRC) message to a user equipment (UE);
• and
• a memory coupled to the at least one processor.

An apparatus for wireless communication, comprising:

• at least one processor configured to determine power information indicative of total power for a designated number of resource elements with equal power per resource element, and to send the power information to a user equipment (UE);
• and
• a memory coupled to the at least one processor.

An apparatus for wireless communication, comprising:

• at least one processor configured to receive power information from a Node B, to determine a power per channelization code for a designated number of channelization codes based on the power information, to determine at least one channel quality indicator (CQI) index for at least one transport block based on the power per channelization code, and to send the at least one CQI index to the Node B;
• and
• a memory coupled to the at least one processor.
