Abstract

The invention provides a DCI analysis method and device in a 5G NR system. The method comprises the steps of acquiring DCI classification information and DCI field analysis information according to received network configuration signaling; dividing the obtained group of DCI loads into different sets according to the DCI classification information and a preset set division rule; filtering the DCI in each set by comparing the DCI reliability; and analyzing the filtered DCI according to the DCI field analysis information. Part of invalid DCI can be filtered out by classifying and filtering DCI, the load of subsequent DCI analysis is reduced, variable-length field judgment is reduced, multiple judgment logics in the DCI analysis process are further reduced, the DCI analysis process can be accelerated, the DCI field information analysis speed of a 5G system is higher, the error rate is lower, and therefore, the problem of rapid and efficient analysis of DCI in a 5G NR system is solved.

Description

technical field [0001] Embodiments of the present invention relate to 5G communication technologies, and in particular to a DCI analysis method and device in a 5G NR system. Background technique [0002] 5G NR is a global 5G standard based on a new air interface design based on OFDM. In the 5G NR cellular mobile communication system, the design of the physical layer downlink channel is similar to that of LTE, and its downlink control channel is also PDCCH (PhysicalDownlink Control Channel), which is used to carry and transmit downlink control information DCI (Downlink ControlInformation). The base station on the network side schedules the transmission of a PDSCH (Physical Downlink Shared Channel) and a PUSCH (Physical Uplink Shared Channel) by transmitting downlink control information. In addition, PDCCH has the following functions: activate or deactivate configurable PUSCH; activate or deactivate the transmission of semi-persistent scheduling PDSCH; notify one or more user...
