摘要： This application discloses an information transmission method in a communication system. According to the method, a master base station sends a request message to a secondary base station for requesting to transfer one or more flows from the master base station to the secondary base station for transmission to a terminal device. The request message carries one or both of identification information of each flow, and information of a data radio bearer (DRB) associated with each flow. The master base station receives a response message from the secondary base station, indicating whether each of the one or more flows is admitted or rejected by the secondary base station. Based on the identification information of the flows, DRBs are mapped to the flows. QoS management of information transmission is more refined, and requirements of 5G communication systems for QoS management of information transmission in a dual connectivity scenario can be met.

摘要： The present invention provides a information processing method at a terminal or a base station. The method at the terminal includes: receiving scheduling information of a physical downlink shared channel (PDSCH) carrying system information, the scheduling information of the PDSCH carried in a master information block (MIB) or downlink control information on an enhanced physical downlink control channel (EPDCCH) sent from the base station, wherein the scheduling information of the PDSCH is used for determining at least one kind of transmission information of the PDSCH; determining the transmission information of the PDSCH according to the scheduling information of the PDSCH. In this way, an extra overhead of a control instruction when a PDCCH is used to schedule a SIB in the prior art is reduced.

摘要： Example configuration methods and apparatus are described. An example communications system includes a master node and a secondary node that jointly provide a service for a terminal. One example method includes generating configuration information for a signaling radio bearer (SRB) by the secondary node, where the SRB is used to transmit a radio resource control (RRC) message between the secondary node and the terminal. The secondary node sends the configuration information for the SRB to the master node, so that the configuration information for the SRB is sent to the terminal through the master node. The secondary node receives a result of configuring the SRB by the terminal by using the configuration information for the SRB. In this way, the SRB can be established on the secondary node, and used for RRC message transmission between the secondary node and the terminal.
