Abstract

The invention discloses a transmission method and a device for transmitting the uplink control information. The method comprises the steps of according to a PUCCH structure, numbering the PUCCH resource loaded on an available resource block (RB) in a PUCCH narrow band; and transmitting the UCI according to the numbered PUCCH resource. The PUCCH structure includes but not limited to a 1x structure and a 2x structure, wherein the 1x structure and the 2x structure are in PUCCH format. According to the technical scheme of the invention, all 1x structures and all 2x structures, designed in PUCCH format and loaded on all available resource blocks in the PUCCH narrow band, are numbered respectively according to the above 1x structure and the above 2x structure. Meanwhile, according to the uniformly numbered 1x and 2x structures in the PUCCH format, the UCI is transmitted, so that the same resource region in the PUCCH narrow band can be shared by the 1x and 2x resources in the PUCCH format. Therefore, unnecessary PUCCH resource cavities are reduced to a certain extent. Moreover, the UCI transmission efficiency within the range of the PUCCH narrow band is improved. As a result, the efficient transmission of the UCI in the newly introduced PUCCH narrow band in the uplink transmission can be realized.

Description

Technical field [0001] The present invention relates to long-term evolution (LTE) technology, in particular to a method and device for realizing uplink control information (UCI, UplinkControlInformation) transmission. Background technique [0002] Machine type communication (MTC, MachineTypeCommunication) or machine-to-machine (M2M, MachinetoMachine) user equipment (UE, UserEquipment) is the main application form of the Internet of Things at this stage. Low power consumption / low cost is an important guarantee for its large-scale application. [0003] At present, the M2M equipment deployed on the market is mainly based on the Global System of Mobile Communication (GSM) system. In recent years, due to the higher spectral efficiency of the Long Term Evolution (LTE) system, and more and more mobile operators have determined LTE as the evolution direction of the future broadband wireless communication system, therefore, LTE-based M2M multiple types of data services It will also be mor...
