1. A method for communicating using multiple-input multiple-output (MIMO) in a wireless network, comprising:
- receiving one or more scheduling grants from a Node B relating to a plurality of uplink streams in MIMO;
determining a primary transmit power and a primary transport block size (TBS) for a primary stream of the plurality of uplink streams;
determining a secondary transmit power and a secondary TBS for a secondary stream of the plurality of uplink streams; and
selecting an enhanced traffic format combination (E-TFC) for transmitting over a configuration of the plurality of uplink streams based on the one or more scheduling grants, wherein the E-TFC has a set of associated states indicating whether a plurality of possible payloads are each supported or blocked over the configuration of the plurality of uplink streams, wherein the determining the primary TBS and the secondary TBS is based in part on the set of associated states,wherein the set of associated states comprise;
a first state indicating whether the E-TFC is supported on the primary stream when both the primary stream and the secondary stream are transmitted;
a second state indicating whether the E-TFC is supported on the secondary stream; and
a third state indicating whether the E-TFC is supported on the primary stream when only the primary stream is transmitted.

Abstract
One or more scheduling grants may be received from a Node B related to a plurality of uplink MIMO streams. A determination may be made as to a primary transport power and a primary transport block size for a primary stream. A secondary transmit power and a secondary transport block size for a secondary stream may also be determined.
