Abstract

The invention discloses an uplink control information transmission method, terminal equipment and network side equipment. The method comprises the following steps: according to bit information of uplink control information UCI to be transmitted, generating a signal sequence bearing the bit information; and mapping the signal sequence to an orthogonal frequency division multiplexing (OFDM) symbol of an uplink control channel (PUCCH) resource for transmission.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for transmitting uplink control information, a terminal device and a network side device. Background technique [0002] In the R-15 protocol, for uplink control information with more than 2 bits, RM code is used for channel coding, and format 2, format 3 and format 4 are used on the Physical Uplink Control Channel (PUCCH) of 5GNR format for transmission. In this manner, a demodulation reference signal (Demodulation Reference Signal, DMRS) is introduced for channel estimation, and the receiving end performs channel estimation according to the DMRS, and restores transmitted UCI information according to the estimated channel. [0003] In related technologies, the receiving end needs to perform channel estimation according to the DMRS, and restore the UCI information transmitted by the UE according to the estimated channel, and the reception complexity is relatively high. ...
