Abstract

Embodiments of the invention disclose a frequency point switching processing method, network devices, a terminal and a computer storage medium. The method comprises that a network device sends a mapping set including identifies and frequency modulating parameters to a terminal; and the network device sends downlink control information in a specific format to the terminal, wherein the downlink control information in the specific format comprises a first identify corresponding to a frequency modulation parameter to be modulated.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a frequency point switching processing method, network equipment, terminal and computer storage medium. Background technique [0002] In a Long Term Evolution (LTE, Long Term Evolution) system, downlink control information (DCI, Downlink Control Information) carried by a physical downlink control channel (PDCCH, Physical Downlink Control Channel) controls data transmission of downlink and uplink shared channels. However, the DCI carried by the PDCCH cannot flexibly switch the uplink and downlink carrier frequencies at the transmission time interval (TTI, Transmission Time Interval) level when scheduling uplink and downlink data transmission. Contents of the invention [0003] In order to solve the existing technical problems, the embodiments of the present invention provide a frequency point switching processing method, network equipment, terminal and computer storage medium...
