Abstract

The embodiment of the invention relates to the technical field of wireless communication, in particular to a signal detection method and device of a PUCCH. The signal detection method and device are used for detecting PUCCH format3 signals. The signal detection method includes the following steps that the equivalent noise power value and the equivalence signal power value of the PUCCH are determined according to received signals on a PUCCH pilot symbol; when the specific value of the equivalence signal power value and the equivalent noise power value is no smaller than a preset threshold value, the PUCCH signals are determined to be detected. Due to the fact that modulation information is not borne on sub-carriers of the PUCCH format3 pilot symbol, the PUCCH format3 signals can be detected with the signal detection method and device of the PUCCH.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a PUCCH signal detection method and equipment. Background technique [0002] In order to meet the requirements of LTE-A (Long Term Evolution-Advanced, long-term evolution upgrade) with a peak downlink speed of 1Gbps and an uplink peak speed of 500Mbps, a maximum transmission bandwidth of 100MHz needs to be provided. Based on this, a carrier aggregation solution is proposed, which aggregates two or more carrier units together to support a larger transmission bandwidth. [0003] When in the carrier aggregation scenario, UE (User Equipment, user equipment) usually needs to feed back more than 2 bits of ACK / NACK (Acknowledgment / Negative Acknowledgment, confirmation / negative confirmation) information. For this situation, LTE-A introduces PUCCH format3 (PUCCH format 3; PUCCH: Physical Uplink ControlChannel, physical uplink control channel) transmission format. ...
