Problems solved by technology

For the same user equipment (User equipment, UE), the base station may allocate SR resources and ACK / NACK resources for the UE in the same subframe, if the UE both sends SR signals on the SR resources in the subframe and The ACK / NACK signal is sent on the ACK / NACK resource in the subframe, and the SR signal and the ACK / NACK signal are superimposed, which will increase the peak-to-average ratio and reduce the transmission power efficiency

Abstract

The invention discloses a control information transmission method, terminal and network side equipment and a communication system. The method comprises the steps: the terminal equipment determines a modulation symbol corresponding to the bit combination to be transmitted and a resource for transmitting the determined modulation symbol according to the mapping relationship between the preset bit combination and the modulation symbol, wherein each bit combination corresponds to one modulation symbol to be transmitted on the first resource or one modulation symbol to be transmitted on the secondresource in the mapping relationship; there are at least two bit combinations with different SR bits and at least two bit combinations with different ACK/NACK bits in the bit combination correspondingto the modulation symbol transmitted on at least one of the first resource and the second resource; and the terminal equipment transmits the modulation symbol corresponding to the bit combination tobe transmitted on the determined resource. Therefore, simultaneous data transmission on two resources located in the same subframe is avoided, and thus the peak-to-average ratio is reduced and the transmission power efficiency and the coverage performance are improved.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a control information transmission method, a terminal, a network side device, and a communication system. Background technique [0002] In a typical wireless communication network (such as LTE), an uplink control channel (Physical Uplink ControlChannel, PUCCH) is used to transmit scheduling request (Scheduling Request, SR), ACK / NACK and other uplink control information (Uplink Control Information, UCI). Among them, the time-frequency and code domain resources of the SR are usually configured by high-level signaling sent by the base station, and the ACK / NACK is configured by the Physical Downlink Control Channel (PDCCH) or the Enhanced Physical Downlink Control Channel (EPDCCH) Corresponding time-frequency and code domain resources. For the same user equipment (User equipment, UE), the base station may allocate SR resources and ACK / NACK resources for the UE in the same ...
