摘要： Example communication methods and apparatus are described. One example method includes: when a terminal side device determines that first downlink control information (DCI) meets a first condition, the terminal side device uses a quantity of physical downlink control channel (PDCCH) candidates that are located in a first time unit and that are in a search space set corresponding to the first DCI as a first quantity of times of monitoring. In the first time unit, the terminal side device monitors, in the search space set corresponding to the first DCI based on the first quantity of times of monitoring, a PDCCH carrying the first DCI.

摘要： The present disclosure relates to handling latency-sensitive traffic, in Ultra-Reliable Low Latency Communication (URLLC) for example, during measurement gaps. Latency-sensitive traffic is detected at a user equipment (UE), and transmission or reception associated with the latency-sensitive traffic is performed at the UE during a time period in which a measurement gap has been configured for the UE to perform measurement of received signal strength. The transmission or reception may be performed instead of or in addition to the measurement. Other embodiments that involve shortening measuring times and shortening or avoiding switching times associated with communication resource switching, for example, are also disclosed.

摘要： Embodiments of the present invention provide a method for transmitting uplink control information and an apparatus, applicable to a multi-carrier system. A user terminal receives physical layer signaling from a network device, where the physical layer signaling includes first indication information. The user terminal determines, according to the first indication information, a bit quantity of periodic CSI that can be sent on a channel resource or a piece quantity of periodic CSI that can be sent on a channel resource. The user terminal determines, according to the bit quantity or the piece quantity of the periodic CSI that can be sent, to-be-sent periodic CSI from periodic CSI corresponding to multiple downlink carriers. The user terminal sends HARQ-ACK information and the to-be-sent periodic CSI on the channel resource.
