Abstract: A slot resource configuration method in wireless communication and a device are provided, to resolve a problem of how to configure a flexible resource included in a new slot structure. In this method, user equipment-specific downlink control information (UE-specific DCI) sent by a base station is received, where the UE-specific DCI indicates a use configuration status of a flexible resource in at least one slot; and the flexible resource is configured according to the use configuration status. This method implements configuration of a flexible resource, so that the flexible resource can be used for communication, thereby improving slot resource usage.

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: A communication method and apparatus are provided, so that a terminal device determines whether DCI obtained through monitoring is repeatedly transmitted on a PDCCH or individually transmitted on a PDCCH. A network device determines first configuration information based on a first condition, and sends the first configuration information to a first terminal device. The first configuration information includes information indicating the first terminal device to monitor a PDCCH candidate based on a span, and includes configuration information of a first PDCCH candidate and a second PDCCH candidate.

Abstract: The disclosure provides example communication methods and apparatuses. One example method includes determining a highest-priority CORESET, so that a terminal device monitors a PDCCH on the highest-priority CORESET. A highest-priority CORESET is determined in M CORESETs belonging to T CORESETs based on one or more of cell identifiers, quasi co-location properties, search space set types, and search space set identifiers that are associated with the M CORESETs in a time unit, and a PDCCH is monitored on the highest-priority CORESET.

Abstract: A terminal device receives a first message, and parses the first message. The first message includes a configuration that is related to PDCCH repetition transmission, and the configuration is related to the PDCCH repetition transmission is for determining M groups of PDCCH candidate sequences. Each group of PDCCH candidate sequences includes K PDCCH candidates, the K PDCCH candidates are for sending same downlink control information, and the K PDCCH candidates included in each group of PDCCH candidate sequences are separately located on different symbols. A PDCCH candidate in the M groups of PDCCH candidate sequences meets a first condition.
