Method and apparatus for enhancing resource allocation for uplink MIMO communication

摘要

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. An enhanced relative grant channel from the Node B, as well as another E-RGC from a non-serving Node B may be received for each of the plurality of uplink MIMO streams.

1. A method for communicating using multiple-input multiple-output (MIMO) in a wireless network, comprising:
receiving, at a user equipment (UE), one or more scheduling grants from a Node B relating to a plurality of uplink streams of the UE in MIMO on a single carrier; receiving an enhanced relative grant channel (E-RGCH) from the Node B, as well as another E-RGCH from a non-serving Node B, for each or a subset of the plurality of uplink streams; determining a primary transmit power and a primary transport block size (TBS) for a primary stream of the plurality of uplink streams, the primary stream carrying a primary data channel (E-DPDCH) on the single carrier; determining a secondary transmit power and a secondary TBS for a secondary stream of the plurality of uplink streams, the secondary stream carrying a secondary data channel (S-E-DPDCH) on the single carrier; and transmitting scheduling information including a defined headroom for the plurality of streams based on consideration of a power of a secondary dedicated physical control channel (S-DPCCH) and a power of a secondary enhanced dedicated physical control channel (S-E-DPCCH) on the single carrier.
