FIELD: radio engineering, communication.
SUBSTANCE: invention relates to wireless communication. Methods and apparatus are provided for uplink MIMO transmissions in a wireless communication system. In particular, scheduled uplink transmission power is allocated between a primary stream including an E-DPDCH and a secondary stream including an S-E-DPDCH. Specifically, a ratio between the power of the E-DPDCH and a primary pilot channel DPCCH, as well as a ratio between the power of the S-E-DPCCH and an unamplified power of the S-DPCCH, each corresponds to a first traffic to pilot power ratio. Further, the transport block size for a primary transport block provided on the E-DPDCH is determined based on the first traffic to pilot power ratio, while the transport block size for a secondary transport block provided on the S-E-DPDCH is determined based on a second traffic to pilot power ratio.
EFFECT: higher throughput and spectral efficiency for uplink transmissions.
