Abstract

The invention provides a transmission method for uplink control information and user equipment. The method is used for transmitting uplink control information through a PUSCH (Physical Uplink Shared Channel). The method comprises the following steps: the user equipment acquires the uplink control information; the user equipment acquires a feedback sub-frame corresponding to the uplink control information; the user equipment maps at least one parameter included in the uplink control information onto an uplink control information resource meta-area of the feedback sub-frame respectively according a priority sequence, wherein the uplink control information resource meta-area is determined at least based on a demodulation reference signal (DM-RS) resource meta-area, and the demodulation reference signal (DM-RS) is positioned on a time slot in the feedback subframe; the user equipment transmits the uplink control information on the feedback sub-frame.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method for transmitting uplink control information and user equipment. Background technique [0002] In the long term evolution system (Long Term Evolution; LTE), in order to realize the effective control and scheduling of the base station on different user equipment (UE) transmissions, the UE needs to feed back some information to the base station through the uplink channel, which is the uplink control information ( Uplink Control Information; UCI), uplink control information UCI includes channel quality indicator (Channel Quality Indicator; CQI), precoding matrix indicator (Precoding matrix indicator; PMI), rank indicator (Rank Indication; RI), hybrid automatic repeat request ( One or any combination of Hybrid Automatic Repeat-request; HARQ) responses. Wherein, the HARQ response includes an acknowledgment (Acknowledgment; ACK) and a negative acknowledgment (...
