  • a terminal device may determine uplink resources through instructions from a network device.
  • terminal devices can determine which logical channels (LCH) data and/or MAC CE are carried on a resource through the logical channel prioritization (LCP) process. For data on different LCHs, resources are allocated to different LCHs based on the priority of the LCH. Generally speaking, terminal devices will prioritize the allocation of resources to high-priority LCHs. Since the uplink resources indicated by the network device for a certain terminal device are generally limited, this may result in that some data associated with LCHs with lower priority may not be transmitted on the current uplink resources. However, the data associated with the LCH with lower priority does not necessarily mean that the data can be sent later, which means that in the above implementation, it is possible that the data associated with the LCH with lower priority is not transmitted, resulting in the failure of the data to be transmitted.
