The method comprises: determining a first switching condition, wherein the first switching condition comprises that the number of transmission failures of a specific hybrid automatic repeat request (HARQ) process of a UE is greater than or equal to a first threshold; counting the number of transmission failures of the specific HARQ process of the UE, and switching a transmission mode of the UE from a first transmission mode to a second transmission mode in response to the number of transmission failures meeting the first switching condition. According to the method of the present disclosure, whether to switch a transmission mode is determined by defining, for a UE which has a plurality of HARQ processes, the number of data transmission failures of which one or which several specific HARQ processes to specifically use, and the technical problem of being unable to determine the number of data transmission failures of which one or which several HARQ processes to specifically use in order to determine whether to switch a transmission mode in the prior art is solved.

摘要： The present invention relates to a method and apparatus for determining random access occasion resource information, and a method and apparatus for indicating random access occasion resource information. The method for determining random access occasion resource information comprises: triggering 4-step contention-free random access (CFRA); and when random access occasion RO resource information independently configured for the terminal does not exist in RO configuration information of the CFRA, determining the RO resource information of the triggered 4-step CFRA according to random access occasion RO resource information of the 4-step contention-based random access (CBRA) of the specified version. According to the present invention, the terminal can determine the RO resource information of the triggered 4-step CFRA according to RO resource information of the 4-step CBRA of the specified version. The technical problem that it is difficult for the terminal to judge which version of RO resource information of the 4-step CBRA is used to determine the RO resource information of the 4-step CFRA when the terminal faces RO resource information of the 4-step CBRA of a plurality of versions is avoided.

摘要： Disclosed in embodiments of the present application are a method and apparatus for reporting a multi-carrier aggregation capability, which can be applied to a communication system such as a long-term evolution (LTE) system, a 5th generation (5G) mobile communication system, a 5G new radio (NR) system, or other future novel mobile communication systems. The method comprises: reporting, by means of first signaling, an aggregation bandwidth class or aggregation capability information supported by a terminal device to a network side device, and reporting, by means of second signaling, an aggregation bandwidth class supported by the terminal device to the network side device, wherein the aggregation bandwidth class reported by means of the second signaling is a fallback aggregation bandwidth class of the aggregation bandwidth class reported by means of the first signaling. By means of the embodiments of the present application, the aggregation bandwidth classes supported by the terminal device can be reported according to the first signaling and the second signaling. By means of the mode, the situation that the network side device cannot be compatible with the aggregation bandwidth class comprised in the first signaling can be avoided, such that avoidance of resource waste can be facilitated.
