摘要
Embodiments herein relate to a method in a base station (12) for providing feedback to a user equipment (14) for transmissions of a secondary stream out of a primary and a secondary stream of the user equipment (14) in an uplink Multiple Input Multiple Output mode. The base station (12) transmits to the user equipment (14), a preferred transmission rank and an offset for the secondary stream in a channel, wherein the offset is to be used by the user equipment (14) when deciding transport block size of the secondary stream and the preferred transmission rank is to be used by the user equipment (14) when deciding a transmission rank.
