Abstract: A time domain resource format configuration method is provided. In addition to configuring time domain resources for an integrated access and backhaul (IAB) node based on a downlink-flexible-uplink time domain resource format, an IAB donor may further configure time domain resources for the IAB node based on an uplink-flexible-downlink time domain resource format, so that the time domain resources can be flexibly configured for the IAB node, to improve utilization and a throughput of the time domain resources in an IAB network.

Abstract: This application provides a method of determining an association between logical channel groups, including: The first backhaul node receives a first buffer status report from a first device, where the first buffer status report is used to determine uplink buffer statuses of one or more first logical channel groups of a MAC entity corresponding to the first backhaul node and the first device. The first backhaul node determines, based on the first logical channel group(s) and a first mapping relationship, one or more second logical channel groups associated with the first logical channel group(s), where a second device is a parent node of the first backhaul node, and the first mapping relationship includes a mapping relationship between the first logical channel group(s) and the second logical channel group(s) of a MAC entity corresponding to the first backhaul node and the second device.

Abstract: A first terminal device has first data to be transmitted on a sidelink and has second data to be transmitted on an uplink. The first terminal device performs medium access control MAC protocol data unit PDU assembly on the first data or does not perform MAC PDU assembly on the first data based on a result of comparison between a transmission priority of the first data and a transmission priority of the second data.

Abstract: 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.

The method includes: a terminal device receiving configuration information sent by a network device, where the configuration information is used to indicate K time sequence relationships, the K time sequence relationships are respectively used for HARQ feedback on K downlink frequency domain resources, and K is a positive integer greater than or equal to 2; and the terminal device sending HARQ feedback information to the network device, where a quantity of downlink control channel monitoring occasions corresponding to the HARQ feedback information is determined based on the K time sequence relationships. According to the foregoing solution, the network device and the terminal device have a unified understanding on the HARQ feedback information. In this way, system robustness is improved.
