Embodiment Construction

[0035] figure 1 It is a schematic diagram of transmitting uplink control information between a base station device and a user equipment in the prior art.

[0036] from figure 1 It can be seen from the figure that the resource occupied by the user equipment on the PUCCH channel of the PCell is the time slot Slot PCell_μ The symbols in (n) are the 3rd to 12th symbols.

[0037] If the UCI sent by the user equipment includes HARQ-ACK, the base station device instructs the user equipment to send HARQ-ACK information on the PUCCH according to the processing capability of the user equipment, which can ensure that the user equipment can transmit HARQ-ACK information at t 01 Complete the reception and demodulation of PDSCH at all times, obtain HARQ-ACK, and complete the processing before sending HARQ-ACK; and, the user equipment at t 02 Completing the PUCCH transmission at all times can ensure that the time delay of the HARQ-ACK transmission meets the time delay requirement of downl...

Abstract

The invention discloses an uplink control information transmission method and device. The uplink control information transmission method comprises the following steps: user equipment determining a physical uplink control channel PUCCH corresponding to uplink control information UCI; sending the UCI in a first PUSCH in a first physical uplink shared channel PUSCH set; wherein each PUSCH contained in the first PUSCH set is overlapped with the PUCCH in time. Therefore, the challenge to the processing capability of the user equipment caused by sending the uplink control information on the PUSCH can be effectively avoided, and meanwhile, the downlink data transmission performance can be ensured.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method and device for transmitting uplink control information. Background technique [0002] In a Long Term Evolution (LTE) system, the user equipment reports uplink control information (Uplink Control Information; UCI) to the base station equipment, and the UCI is used as a basis for the base station equipment to schedule downlink data or uplink data transmission of the terminal equipment. For example: the base station device sends downlink service data through a physical downlink shared channel (Physical Downlink Shared Channel; PDSCH); Physical Uplink Shared Channel (PUSCH) feeds back the confirmation ACK or non-confirmation NACK information of the downlink service data of the user equipment, so that the base station equipment determines whether to reschedule the downlink service data or schedule new downlink service data to the user equipment. ...
