A method for selecting a transport format in an uplink multiple-input multiple-output system and a related method and a device are used by a user equipment to select a transport format in a case in which the user equipment is in a dual-stream transmission mode of the ULMIMO and inter-stream interference is considered. The method includes: receiving, by the user equipment, a reference E-TFC set and a primary-stream channel quality difference in the dual-stream transmission mode that are sent by a base station; acquiring A ed 2 according to an SG allocated by the base station to the user equipment within a TTI; if transmit power of the primary stream is obtained according to primary-stream transmit power granted by the base station, acquiring E-TFCI 1 according to the primary-stream channel quality difference and the A ed 2 ; if the transmit power of the primary stream is obtained according to remaining transmit power, which is calculated according to a limit value of maximum transmit power of the user equipment, calculating A ed ¹ 2 according to the remaining transmit power; calculating A edm �¢ 1 ¹ 2 according to the primary-stream channel quality difference, the A ed 2 , and the A ed ¹ 2 ; calculating E - TFCI 1 ¹ according to the reference E-TFC set and the A edm �¢ 1 ¹ 2 ; and selecting from the E-TFCI 1 and the E - TFCI 1 ¹ an indicator, which has a smaller value, as an E - TFCI 1 º , and selecting a transmission block size corresponding to the E - TFCI 1 º . |
