Method for assisting in uplink transmission, and base station

摘要

Embodiments of the present invention provide a method for assisting in uplink transmission and a base station. The method for assisting in uplink transmission includes: acquiring, by a first base station, auxiliary uplink control information of a user equipment; sending, by the first base station, the auxiliary uplink control information to a second base station; and performing, by the second base station, uplink data scheduling for the user equipment according to the auxiliary uplink control information. Therefore, a problem in which the second base station cannot acquire or correctly demodulate uplink information sent by the user equipment and consequently cannot schedule uplink data from the user equipment is solved.

1. A method for assisting in uplink transmission, the method comprising:
acquiring, by a first base station, auxiliary uplink control information of a user equipment; sending, by the first base station, the auxiliary uplink control information to a second base station for scheduling uplink data for the user equipment according to the auxiliary uplink control information; determining, by the first base station, at least one of scheduling information, a happy bit, and reference grant information is the auxiliary uplink control information of the user equipment; acquiring, by the first base station, the scheduling information and the happy bit from the user equipment; determining, by the first base station, according to quality of an uplink link from the user equipment to the first base station, the reference grant information that needs to be sent to the user equipment; and sending, by the first base station, timing information to the second base station if
the first base station determines the reference grant information is the auxiliary uplink control information, orthe first base station determines the scheduling information is the auxiliary uplink control information, orthe user equipment separately sends the scheduling information and the first base station determines the scheduling information separately sent by the user equipment is the auxiliary uplink control information.
