Abstract: Disclosed are a radio resource configuration method and apparatus, a user equipment and a network element. The radio resource configuration method includes that: a user equipment (UE) receives a message of a radio resource configuration from a first signaling radio bearer (SRB) of a first radio access technology (RAT), where the message carries information of a first configuration, and the first configuration is a configuration of a radio resource of the first RAT; and when the UE fails to configure the radio resource of the first RAT according to the information of the first configuration, the UE sends a response message of the radio resource configuration to indicate that the radio resource configuration of the first RAT fails.

Abstract: Methods, systems, and devices related to mobility robustness in dual connectivity mode are described. In one representative aspect, a method for wireless communication includes receiving, at a master communication node, a first message from a first secondary communication node requesting a change from a first connection to a second connection. The method includes transmitting a second message to the second secondary communication node to request establishing the second connection. The method includes receiving a third message from the mobile device confirming a configuration of the second connection. The method includes receiving a fourth message from the mobile device indicating a failure of the second connection. The method further includes transmitting a fifth message to the first secondary communication node to report that the change from the first connection to the second connection is an improper change.

Abstract: Described are methods, systems and devices for group-based system information (SI) communication to reduce reservations of preambles or RACH resources are the number of SI increase. In some embodiments, SI messages into divided into SI groups, preamble/RACH resources are only reserved for each of the groups, and SI request windows are implemented. In an example, an SI request window precedes each set of SI windows corresponding to a group of SI messages, and an SI request is transmitted only in an SI request window. The disclosed implementation may increase the efficacy of supporting a greater number of users, which may be ubiquitous in 5G implementations.

Abstract: Method, systems and devices for data transmission in a cell having large transmission delay. In particular embodiments, assisting information may be sent from a network device to a communication device. The assisting information may be used to calculate a timing offset to determine a correct transmission time to compensate for propagation delay in large cell with significant propagation delay.
