Abstract: Preconfiguration parameters, such as survival time and communication service availability target, are part of the application layer. Methods, systems, and devices can wirelessly communicate those parameters on the Radio Access Network (“RAN”) side. A threshold of survival time can be used for triggering Packet Data Convergence Protocol (“PDCP”) duplication. The parameters can be provided by an Access and Mobility Management Function (“AMF”) to a user equipment (“UE”) device by Quality of Service (“QoS”) information or non-access stratum (“NAS”) signalling. The communicated parameters can be used for establishing priorities of logic channels (“LCH”).

Abstract: The present invention provides a resource allocation method and device. The method includes: sending, by a base station, a resource allocation parameter to a terminal, where the resource allocation parameter includes a starting narrowband index and a resource position, where the starting narrowband index is used for indicating a narrowband resource and/or a wideband resource for the terminal to establish a physical shared channel. The embodiments of the present invention solve the problem in existing art that resource allocation for physical downlink shared channel (PDSCH)/physical uplink shared channel (PUSCH) only considers a bandwidth limitation of a 1.4 MHz narrowband so that a user equipment (UE) cannot support machine type communications (MTC) applications with a higher data rate, achieving an effect of being capable of supporting MTC traffic with a higher data rate.

Abstract: Provided are a data transmission method and device, a base station, a terminal and a readable storage medium. A paging message is sent to the terminal, where the paging message carries a cell radio network temporary identifier (C-RNTI). Then, downlink data is transmitted according to the C-RNTI. In this way, the transmission of the downlink data is indicated by directly carrying the C-RNTI in the paging message.
