Abstract: A common CORESET determining method, an apparatus and a non-transitory computer-readable storage medium are provided. The method includes: receiving configuration information, wherein the configuration information indicates where a physical resource block occupied by a first common control resource set is located in a first downlink bandwidth part; determining a frequency domain resource of the first common control resource set based on a frequency domain resource of the first downlink bandwidth part and the physical resource block occupied by the first common control resource set within the first downlink bandwidth part; and monitoring a physical downlink control channel in the first common control resource set before the first downlink bandwidth part configured by a SIB1 takes effect to obtain scheduling control information. According to this application, complexity of determining a frequency domain location of the first control resource set can be reduced.

Abstract: An information indication method is provided, including: A terminal-side device receives first higher layer signaling from a network-side device, where the first higher layer signaling is used to configure N bandwidth parts BWPs, and N is a positive integer. The terminal-side device receives downlink control information from the network-side device, where the downlink control information includes an indication field. When N is less than a maximum quantity of BWPs that can be configured through the first higher layer signaling when the terminal-side device is in a connected mode (for example, an RRC connected mode) or a maximum quantity of BWPs that can be determined by using candidate bit states of the indication field that is used to determine an active BWP and that is in the downlink control information, the indication field indicates a position of the active BWP located in an initial BWP and the N BWPs.

Abstract: The present disclosure relates to channel state information transmission methods and apparatus. One example method includes receiving first higher layer signaling sent by a network device, where the first higher layer signaling is used to indicate a first physical uplink control channel, and the first physical uplink control channel is a channel used to periodically report channel state information (CSI), receiving downlink control information sent by the network device, where the downlink control information is used to schedule a physical downlink shared channel, and sending the CSI by using the first physical uplink control channel and a second physical uplink control channel, or sending the CSI by using a second physical uplink control channel.

Abstract: Embodiments of this application provide a blind detection method. A terminal side device receives first indication information from a network side device, where the first indication information is used to determine at least one of N time units, a first time unit in the N time units corresponds to a type of terminal operation, the terminal operation is not performing a first operation, a second operation, and a third operation, the N time units belong to a same transmission time unit, and any one of the N time units includes at least one symbol, where N is an integer greater than 0. The terminal side device determines the N time units based on the first indication information, and performs the corresponding terminal operation in the first time unit in the N time units.
