Abstract

The present application provides a method and device for determining uplink control channel resources, the method includes: in a time slot, when the first uplink resource and the second uplink resource overlap in the time domain, according to a preset rule, from the first uplink resource The number of OFDM symbols included in the resource set is less than or equal to 2 or the first resource is determined from the uplink resources whose format is the first format, and the first uplink information and the second uplink information are sent through the first resource. Uplink information, the method can realize that when the resources carrying HARQ-ACK and the resources carrying CSI overlap in the time domain, the base station and the terminal equipment are provided with determined uplink resources, and the reliability of uplink transmission is improved.

Description

technical field [0001] The present application relates to the communication field, and more specifically, to a method and device for determining uplink control channel resources. Background technique [0002] Currently, when a user equipment (user equipment, UE) is in a radio resource control (radio resource control, RRC) connection state, a base station (gNode B, gNB) will configure multiple physical uplink control channel (physical uplink control channel, PUCCH) resources for the UE set (PUCCH resource set), and each resource set includes multiple PUCCH resources. The UE determines a resource set according to the range of the number of bits of the uplink information to be sent, and after receiving the downlink control information (downlink control information, DCI) sent for scheduling signaling, it will use the uplink resource indication field (PUCCH resource indicator resource field) to determine the resources specifically used to transmit uplink information. [0003] H...
