1. A method of wireless communication, comprising:

  • transmitting a MIMO uplink utilizing a first stream and a second stream in a dual stream mode;

    receiving HARQ feedback indicating a decoding failure of a packet on the second stream and a decoding success of a packet on the first stream;

    receiving a command to switch from the dual stream mode to a single stream mode;

    determining to only transmit the first stream in response to the command;

    allocating at least some portion of power from the second stream to the first stream when a determination is made to only transmit the first stream; and

    transmitting, on the first stream, a HARQ retransmission corresponding to the decoding failure of the packet on the second stream.
