Abstract

The present invention provides a 5G uplink physical layer channel processing method, device, equipment and product, and relates to the technical field of communications. The method comprises the following steps: removing a cyclic prefix from acquired uplink time domain data, and acquiring a first time domain offset value of the uplink time domain data after removal processing on each preamble symbol; performing first fast Fourier transform on the uplink time domain data subjected to removal processing to obtain first frequency domain data; performing second fast Fourier transform on the corresponding first frequency domain data to obtain time domain data corresponding to the preamble symbol; and performing cyclic shift based on the first time domain data and the first time domain offset value, compensating the first time domain offset value of each preamble symbol, and recovering a correct preamble symbol. According to the invention, the detection time delay of the PRACH channel is reduced, the detection efficiency is improved, and the correctness of PRACH detection is ensured, so that the user perception is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a processing method, device, equipment and product for a 5G uplink physical layer channel. Background technique [0002] At present, the uplink physical layer channels of the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) in the 5th generation mobile communication (5-Generation, 5G) new air interface (New Radio, NR) include three types: [0003] 1. Physical Uplink Share CHannel (PUSCH), used to carry uplink service data; [0004] 2. A physical uplink control channel (Physical Uplink Control Channel, PUCCH), used to carry uplink control signaling; [0005] 3. A physical layer random access preamble channel (Physical Random Access Channel, PRACH), used for sending a preamble. [0006] Wherein, the PUSCH / PUCCH channel has the same uplink time slot structure, which is different from the time slot structure of the PRACH channel. [00...
