Abstract: Disclosed are a method and an apparatus for controlling uplink power, so as to solve a problem that in a scenario of double connections, when a terminal performs uplink transmission, there is no corresponding solution to control uplink power. The method in the present invention comprises: a terminal determining uplink information to be sent on an uplink carrier, the uplink information comprising uplink information corresponding to a first base station and uplink information corresponding to a second base station; and the terminal determining, according to at least one group of power control parameters pre-configured for calculating transmit power of an uplink channel bearing the uplink information, transmit power of at least one uplink channel bearing the uplink information, and sending corresponding uplink information on the at least one uplink channel of the uplink carrier according to the transmit power of the at least one uplink channel. It is ensured that the terminal uses more appropriate transmit power on the uplink carrier to send uplink information of different base stations, thereby avoiding power limitation and improving power utilization and transmission efficiency.

Abstract: The technical solutions according to the present disclosure perform configuring the uplink control channel resources for a terminal equipment, by means of a semi-statically configured initial resource and a dynamically configured ACK/NACK Resource Indication (ARI) information which indicates a selection result or offset information. Thereby an uplink control channel resource configuration solution is realized by combining dynamic indication with semi-static indication. The method according to the present disclosure can be achieved in a simple and easy manner, and simultaneously can be used in a Frequency Division Duplexing (FDD) system and a Time Division Duplexing (TDD) system.

Abstract: Disclosed are a method and device for transmitting uplink control information (UCI). By applying technical solutions of embodiments of the present invention, implemented is a method for simultaneously transmitting an ACK/NACK and cycle CSI on a channel resource corresponding to a current subframe: dynamically determining, on the basis of a threshold number of bits simultaneously transmitted with the UCI in the current subframe, also of the maximum number of feedback bits and of the minimum number of feedback bits of the ACK/NACK in the current subframe, ACK/NACK bits and CSI bits simultaneously transmitted in the current frame, thus ensuring that the sum of the bits simultaneously transmitted does not exceed the threshold number of bits simultaneously transmitted with the UCI in the current subframe, preventing as much as possible ACK/NACK merging and CSI discarding, and protecting to the maximum extent the accuracy and completeness of UCI transmission.

Abstract: The present invention provides a method and apparatus for processing uplink control information (UCI) and a method for transmitting the UCI based on a multiple input multiple output system, which processing method comprises: repeating ACK/NACK source bits and/or rank indicator (RI) source bits in the uplink control information to form M groups, with each group corresponding to a code word (S302), wherein M is the total number of code words; carrying out channel encoding on the ACK/NACK source bits and/or RI source bits of each code word to obtain QACK*Li output bits (S304), wherein QACK is the channel encoding output bits corresponding to each layer in a certain code word, L is the total number of layers, and the layer number corresponding to the i-th code word is Li; and multiplexing and interleaving the output bits and the data bits of the corresponding code word (S306). The present invention solves the problems of transmission and channel encoding of the ACK/NACK and/or RI in the multiple input multiple output (MIMO) system, and at the same time takes into account high load situations and backward compatibility.
