Patent ID: 8514820

Claim:
A method, comprising: determining a slot format for transmitting feedback information for a plurality of serving cells via high speed dedicated physical control channel (HS-DPCCH) based on a number of configured secondary serving cells and whether multiple input multiple-output (MIMO) is configured in the plurality of serving cells; sending the feedback information in accordance with the determined slot format, wherein when the plurality of serving cells comprises a primary serving cell and two enabled secondary serving cells, and the two enabled secondary serving cells comprises an active secondary serving cell and a deactivated secondary serving cell, hybrid automatic repeat request (HARQ) feedback for the primary serving cell and HARQ feedback for the active secondary serving cell is jointly encoded to form a jointly coded HARQ feedback, wherein the jointly encoded HARQ feedback is sent in a first portion of a time slot allocated for HARQ feedback transmission, and the jointly encoded HARQ feedback is repeated in a second portion of the time slot allocated for HARQ feedback transmission.
