    Abstract: Provided are a data transmission method and apparatus and a computer storage medium. The method may include: a source Distributed Unit (DU) reports a packet data convergence protocol (PDCP) transmission state report to a source Centralized Unit (CU), where the PDCP transmission state report enables the CU to determine which PDCP protocol data unit (PDU) data is not successfully received by a UE; and the PDCP PDU data which is not successfully received by the UE are retransmitted to the UE via a target DU.

    Abstract: A method for carrying out data integrity protection on a communication network. According to an implementation, a wireless communication device indicates, to a wireless network, the maximum data rate up to which integrity protection is supported for user plane data. A network node (e.g., a node of the core network, such as an SMF) receives this information and determines whether or not to enable integrity protection for user plane data based on the information (possibly in conjunction with other information such as the minimum data rate to be supported, etc.). The network node then communicates the decision to enable or disable integrity protection to a RAN node (e.g., a wireless base station).

    Abstract: Some techniques for efficiently indicating a mapping relationship from physical random access channel preambles and/or random access resource specific to one or more system information blocks in a wireless communication network are described. One example method includes transmitting, from a network node, a message that identifies a number of random access preambles that are reserved for transmissions of system information requests by mobile devices.
