摘要： This application provides a control channel detection method, apparatus, and device. The method includes: A terminal device determines that resources of at least two candidate control channels overlap, where any two of the at least two candidate control channels are located in different search spaces; and the terminal device detects only at least one first candidate control channel in the at least two candidate control channels. This improves control channel detection reliability.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
