Abstract: A client device, a network access node for management of control channel monitoring capabilities and corresponding methods and computer program are described. The client device transmits a first control message to the network access node to inform the network access node about its CCH monitoring capabilities. The first control message indicates a set of CCH monitoring capabilities supported by the client device; each CCH monitoring capability in the set indicates a first CCH monitoring capability for a first CCH monitoring mode and a second CCH monitoring capability for a second CCH monitoring mode. Based on the first control message, the network access node can determine a CCH monitoring capability from the set of CCH monitoring capabilities for the client device and configure the client device with the determined CCH monitoring capability. Thereby, flexible CCH monitoring which can be adapted to different service requirements and traffic situations is provided.

Abstract: The disclosure provides example communication methods and apparatus. 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: 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.

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: This application provides a communication method, including: A terminal device receives configuration information from a network device. The configuration information is used to configure at least two frequency bands for the terminal device, and the at least two frequency bands include a first frequency band and a second frequency band. The terminal device receives first scheduling information from the network device. The first scheduling information indicates a target resource block (RB) for data transmission. The terminal device performs data transmission with the network device on a same symbol by using a first RB on the first frequency band and a second RB on the second frequency band. There is a first common resource block (CRB) deviation between the first RB and the second RB, and the target RB includes the first RB or the second RB.
