Title: METHOD FOR DETERMINING BASIC NUMEROLOGY, TERMINAL, AND NETWORK DEVICE
Abstract:
Disclosed in the present application are a method for determining a basic numerology, a terminal, and a network device. The method comprises: a terminal descrambles a cyclic redundancy check code (CRC) in downlink control information by using at least one first radio network temporary identifier (RNTI), and determines a first RNTI that successfully descrambles the CRC among the at least one first RNTI, as a target RNTI; and according to the target RNTI and a correspondence between the first RNTIs and basic numerologies, the terminal determines a target basic numerology used for transmitting data. In embodiments of the present application, a CRC in downlink control information is scrambled by using a first RNTI, a basic numerology is indicated by means of the first RNTI, and accordingly, it is avoided that an indication domain used for indicating the type of the basic numerology needs to be added in the downlink control information in the prior art, so as to reduce signaling overheads caused by the basic numerology for indicating transmitted data.
