Patent ID: 8675508

Claim:
A method for transmitting a plurality of data streams from a primary station to a secondary station on a plurality of transmission beams, said method comprising: at the secondary station measuring the channel quality corresponding to each transmission beam, and signaling, via two slots of three slots of feedback information (FBI) bits of a high-speed dedicated shared channel subframe, at a first rate to the primary station in a first indicator a channel quality information (CQI) report representative of the quality of the beams, and signaling, via a third slot of the three slots of the feedback information (FBI) bits of the high-speed dedicated shared channel subframe, at a second rate, greater than the first rate, in a second indicator a number of data streams that can be transmitted on the transmission beams, wherein the second indicator (i) only indicates a number of available data streams that can support a codeword, (ii) enables rapid adjustment of a number of simultaneously transmitted codewords without requiring channel quality information to be transmitted every subframe, and (iii) permits a flexible control of a number of codewords allocated to the plurality of data streams; and at the primary station transmitting the data streams on the basis of the first and second indicators.
