Abstract: This application provides a resource determining method and an apparatus, to mitigate a resource conflict between an LTE-V2X apparatus and an NR-V2X apparatus. In the method, a terminal apparatus may obtain configuration information, first sidelink control information, and second sidelink control information. The first sidelink control information is control information used for E-UTRA radio access, and the second sidelink control information is control information used for NR radio access. The terminal apparatus determines an available time-frequency resource based on the first sidelink control information and the second sidelink control information. Based on the foregoing solution, the terminal apparatus can determine, in a resource pool based on the first sidelink control information and the second sidelink control information, a time-frequency resource that can be used by the terminal apparatus to send sidelink control information and data information, thereby mitigating the resource conflict between the LTE-V2X apparatus and the NR-V2X apparatus.

Abstract: Example quasi co-location information determining methods and apparatus are described. One example method includes determining a quantity X of pieces of quasi co-location QCL information, where X is a positive integer. When it is determined that the quantity X of pieces of QCL information is two, and that DCI corresponding to a current data channel does not indicate QCL information of an antenna port of the data channel, or that an interval between the current data channel and the DCI corresponding to the data channel is less than a threshold, two pieces of default QCL information of the antenna port of the data channel are determined.
