1. A method for SCS configuration between channel, applied to a network side device and comprising:
transmitting configuration information to a terminal, wherein the configuration information is used to indicate subcarrier space (SCS) configuration information of a channel on a same bandwidth part (BWP), and different channels have different SCS configuration information or a same channel has different SCS configuration information in different cases; wherein
in a case that a physical downlink control channel (PDCCH) and a PDCCH have different SCS configuration information, the transmitting the configuration information to the terminal comprises:
transmitting at least two pieces of SCS configuration information to the terminal through system information or radio resource control (RRC) signaling; wherein
the method further comprises:
transmitting at least one selection rule to the terminal through system information or RRC signaling, a selection rule being used to determine SCS of a target PDCCH according to the at least two pieces of SCS configuration information; wherein
the selection rule comprises at least one of:
determining SCS configuration information of the target PDCCH according to the type of the search space of the target PDCCH;
determining SCS control information of the target PDCCH according to a downlink control information (DCI) format monitored on the search space of the target PDCCH; or
determining SCS configuration information of the target PDCCH according to an aggregation level (AL) monitored in the search space of the target PDCCH.
