Abstract

The embodiment of the invention discloses a method and equipment for transmitting uplink control information. The method comprises the following steps: acquiring multiple first phase rotation coefficients and the first orthogonal code at a terminal equipment side; acquiring multiple second phase rotation coefficients and the second orthogonal code; generating a first group of OFDM symbols carryingthe uplink control information based on multiple first phase rotation coefficients and the first orthogonal code; generating a second group of OFDM symbols carrying the reference information based onmultiple second phase rotation coefficients and the second orthogonal code; and sending the first group of OFDM symbols and the second group of OFDM symbols in the same time slot. The embodiment of the invention further provides corresponding equipment. Through the method disclosed by the embodiment of the invention, the independent transmission of the control information with less information bit can be supported, and the reuse of the existing transmission format on the same resource is realized.

Description

technical field [0001] Embodiments of the present disclosure generally relate to the communication field, and in particular, relate to a method and device for transmitting uplink control information. Background technique [0002] Currently, the MulteFire Alliance is conducting research on enhanced physical uplink control channel (ePUCCH) transmission in uplink subframes in unlicensed frequency bands, so as to support independent (standalone) operation or dual connectivity in unlicensed frequency bands. Different from the conventional Physical Uplink Control Channel (PUCCH), ePUCCH should be based on B-IFDM (Block-Interleaved Frequency Division Multiplexing) to facilitate multiplexing with the Physical Uplink Shared Channel (PUSCH). However, currently there is no suitable transmission method that not only supports independent transmission of certain uplink control information but also supports a high number of user multiplexing. Contents of the invention [0003] In genera...
