摘要： A time domain resource indication method includes sending, by a first node, first time domain resource configuration information to at least one second node. The first time domain resource configuration information is used by the at least one second node to determine second time domain resource configuration information sent by the at least one second node to at least one third node. The first time domain resource configuration information indicates first time domain resources of a link between the first node and the at least one second node. The second time domain resource configuration information indicates second time domain resources of a link between the at least one second node and the at least one third node.

摘要： A carrier scheduling method and apparatus. The method comprises determining search spaces of downlink control channels corresponding to at least two first transmission time units on a first carrier, where the at least two first transmission time units are scheduled in one second transmission time unit on a second carrier, and the downlink control channels are in a one-to-one correspondence with the first transmission time units; and obtaining, in the search spaces, the downlink control channels corresponding to the at least two first transmission time units. In this application, a plurality of transmission time units on another carrier are scheduled in a cross-carrier manner, thereby improving transmission resource utilization.

摘要： Embodiments of this application provide an information transmission method and a device. The method includes: sending, by a first device, M signals to a second device through N ports, where N and M are integers, and M≥N≥2; and receiving, by the first device, measurement information sent by the second device, where the measurement information is determined by the second device based on the M signals, and the measurement information is used to indicate a relationship between the N ports. Therefore, in the embodiments of this application, the relationship between the ports is determined by using characteristics of the ports on a side of the second device, so that the first device can relatively accurately determine the relationship between the ports, and the first device can perform appropriate communication management on the plurality of ports. This improves performance of transmission between the first device and the second device.

摘要： The application relates to a user equipment configured to communicate using a first signal or channel via a first resource with a first device and using a second signal or channel via a second resource with a second device. The user equipment is configured to: measure the first signal or channel in the first resource for a beam or link failure detection; and, in response to a detected failure in the first resource, transmit the second signal or channel via the second resource to the second device for a failure recovery request. The first device can be a further user equipment and the second device can be a base station, wherein the first resource is a sidelink resource between the user equipment and the further user equipment and the second resource is an uplink resource between the user equipment and the base station.
