Problems solved by technology

However, in the above method, once the PUCCH format 3 resource reserved semi-statically is allocated to a certain UE, the resource will be occupied by the UE regardless of whether the UE needs to transmit periodic CSI and HARQ-ACK at the same time. The resource overhead of transmitting uplink control information is too large, and the resource utilization rate is low

Abstract

The invention discloses a method, user equipment and a base station for transmitting uplink control information. The method comprises receiving a physical downlink control channel sent from the base station, wherein the physical downlink control channel comprises indication information used for indicating physical uplink control channel resources used for transmitting the uplink control information; acquiring the physical uplink control channel resources used for transmitting the uplink control information in a first resource group and or a second resource group which are configured in a semi-static state according to whether period channel state information included in the indication information and the uplink control information or not; and sending the uplink control information to the base station on a physical uplink control channel corresponding to the physical uplink control channel resources. The method, the user equipment and the base station for transmitting the uplink control information can transmit the uplink control information, reduce resource expenses of the physical uplink control channel in transmission of the uplink control information and improve the resource utilization rate.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for transmitting uplink control information in the communication field, a user equipment and a base station. Background technique [0002] The Long Term Evolution-Advanced (LTE-A for short) system is a 3rd Generation Partnership Project (3GPP for short) Long Term Evolution (LTE-A for short) system. ) system further evolution and enhanced system. In the LTE-A system, in order to meet the peak data rate requirements of the International Telecommunication Union for the fourth-generation communication technology, the Carrier Aggregation (CA) technology, also known as the Spectrum Aggregation technology, is introduced. Or bandwidth extension (Bandwidth Extension) technology. In carrier aggregation, the spectrums of two or more component carriers are aggregated together to obtain a wider transmission bandwidth. The spectrums of each component carrier can be adjacent continu...
