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 present application discloses a method and device for transmitting uplink control information, including: the user equipment determines the physical uplink control channel PUCCH corresponding to the uplink control information UCI; the first PUSCH in the first physical uplink shared channel PUSCH set sends the UCI ; Wherein, each PUSCH included in the first PUSCH set overlaps with the PUCCH in time. In this way, 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 at the same time, the performance of downlink data transmission can be guaranteed.

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. ...
