Abstract: Disclosed are methods, apparatus and systems for cell information acquisition and reporting. One method includes receiving a request for configuration information and a synchronization block, determining that the synchronization block is not associated with the configuration information, and transmitting a failure indication in response to the request. Another method includes receiving a request for configuration information and a first synchronization block, determining that the first synchronization block is not associated with the configuration information, and the first synchronization block comprises information related to a second synchronization block that is associated with the configuration information, and determining whether a radio frequency retuning operation can be performed in order to obtain the configuration information.

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).
