Abstract: 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.

Abstract: This application discloses a communication system including a master base station and a secondary base station, both connecting with a terminal. In the communication system, the master base station sends a first message to the secondary base station for allocating transmission resources for one or more flows to be transmitted between the secondary base station and a terminal, wherein the first message carries one or both of: identification information of each flow to be transmitted, and information of a data radio bearer (DRB) associated with each flow to be transmitted, then the secondary base station may determine a mapping relationship between a DRB and an admitted flow according to the first message. Moreover, the master base station sends DRB configuration information to the terminal. Therefore, requirements of 5G communication systems for QoS management of information transmission in a dual connectivity scenario can be met.

Abstract: Embodiments of this application provide a communication method, a terminal and a base station. The method includes: receiving, by a terminal, a scheduling request resource configuration sent by a base station, where the scheduling request resource configuration indicates an uplink resource type or logical channel information; and sending, by the terminal, a scheduling request to the base station via a target scheduling request resource based on the scheduling request resource configuration and uplink data, where the target scheduling request resource indicates a target uplink resource type, and the scheduling request resource configuration includes the target scheduling request resource. In the embodiments of this application, when diversity of the uplink data is considered, the base station configures different scheduling request resources for different service characteristics, and the terminal selects different scheduling request resources for different service characteristics, to improve effectiveness of uplink service transmission.

Abstract: A data transmission, by a terminal device, is described that improves data transmission efficiency while ensuring a transmission latency. The data transmission method includes sending a first transport block to a radio access device for X times by using a shared resource that is configured by the radio access device for at least one terminal, where the terminal is one of the at least one terminal, and X>0. The method further includes determining a dedicated resource allocated by the radio access device to the terminal, and sending the first transport block to the radio access device for Y times by using a target resource. The target resource includes the dedicated resource, and Y≥0.
