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.

Abstract: The present invention relates to a method and an apparatus for supporting user equipment in task execution, which are used to resolve a problem that a result of measurement and/or synchronization performed by user equipment is erroneous. In the method, a first network-side device acquires duration of a cell working state, where the duration of the cell working state includes duration for which a cell performs signal sending and/or duration for which the cell does not perform signal sending; and the first network-side device determines a time for user equipment to perform measurement and/or synchronization, where the time for the user equipment to perform measurement is within a range of duration for which a to-be-measured cell performs signal sending, and the time for the user equipment to perform synchronization is within a range of duration for which a serving cell performs signal sending.

Abstract: This application provides a data transmission method and an apparatus, in which two radio access network devices share a resource. A first radio access network device determines a resource occupation status corresponding to a different status of a second access network device on a shared resource. The first radio access network device indicates the resource occupation status to a terminal device served by the first radio access network device. The terminal device determines an available resource in a shared carrier based on the resource occupation status, and communicates with the first access network device using the available resource. The first radio access network device can perform communication on the shared resource regardless of a status of the second radio access network device on the shared resource, so that the two radio access network devices flexibly and efficiently coexist in the shared carrier. This improves utilization of the shared resource.
