Abstract: Techniques are described for facilitating an inter-Radio Access Technology (RAT) selection or measurement process for a dual-mode or a multi-mode device. For example, a wireless communication method includes a network node transmitting to a communication node a system information block (SIB) that includes information about Radio Access Technologies (RATs). The information includes any one or more of a first carrier priority value and a first threshold value of a serving frequency associated with a RAT, a second carrier priority value and a second threshold value of a serving cell associated with the RAT, an indicator to indicate existence of one or more additional RATs, carrier information for the one or more additional RATs, and access information to access the one or more additional RATs.

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.
