8 . The terminal equipment according to claim 1 , wherein,
the processor is further configured to determine, when the first PUSCH can be transmitted by the physical layer of the terminal equipment, whether to obtain a PDU for the first PUSCH, by the media access control (MAC) layer.
9 . The terminal equipment according to claim 8 , wherein
the processor is further configured to obtain, when an uplink grant with which the first PUSCH associates is considered as a prioritized uplink grant, a PDU for the first PUSCH, by the MAC layer of the terminal equipment.
