Abstract: A coding scheme determining method and apparatus are provided. In various embodiments, a base station device sends, to a terminal device, higher layer control signaling, physical layer control signaling, or a synchronization signal that carries coding scheme indication information. In some embodiments, a terminal device sends, to a base station device, a capability information report message that carries coding scheme indication information, so that the base station device or the terminal device can clearly and flexibly indicate a coding scheme. At least one information block size IBS greater than or equal to a preset first specified value X is determined, and an IBS is selected from the at least one IBS to code an information block of bits or a code block of the information block of bits. X and a coding scheme are determined by a scenario, information type, and/or service type.

Abstract: The present disclosure discloses a terminal, a base station, a network controller, a system, and a transmission method. The terminal includes: a receiving module, configured to receive configuration information of at least one air interface-specific path sent by a base station, where the air interface-specific path is used to transmit application data corresponding to at least one application; and a sending module, configured to: if the to-be-sent application data is discontinuously transmitted and has a length less than a preset threshold, use the at least one air interface-specific path to send the application data to the base station. According to embodiments of the present disclosure, when a terminal transmits data or signaling that is discontinuous and has a relatively small length, consumption of network signaling resources is reduced, so that a normal network service properly runs.
