Problems solved by technology

[0004] The existing technology is aimed at intra-site carrier aggregation, that is, PCell and SCell belong to the same base station, there is no delay in data and information exchange, and the RLC layer performs grouping according to the application data of the MAC layer, without considering the impact of delay
[0005] It can be seen that the following technical problems exist in the prior art. During inter-site carrier aggregation, PCell and SCell do not belong to the same base station, and data and information are transmitted between PCell and SCell in different base stations. The scheduling of the MAC layer on the SCell side There is a delay effect, which reduces the user experience

Embodiment Construction

[0129] In the embodiment of the present invention, by providing a method and device for obtaining and sending data, based on the size of the first data amount applied by the secondary serving cell SCell to the primary serving cell PCell, it is determined that the RLC layer of the primary serving cell PCell needs to forward the data to the primary serving cell PCell. The size of the second data amount of the secondary serving cell SCell, wherein, the primary serving cell PCell and the secondary serving cell SCell belong to different base stations; according to preset rules, it is determined that the primary serving cell PCell needs to be forwarded to the The preset size of each RLC PDU of the secondary serving cell SCell; based on the size of the second data volume and the preset size of each RLC PDU, obtain the information that the primary serving cell PCell needs to forward to the secondary service M RLC PDUs in the cell; and periodically or event-transferred to the RLC layer ...

Abstract

The invention provides a method and device for obtaining and issuing data. The method for obtaining the data is characterized by, according to the size of a first data volume applied by a secondary cell SCell to a primary cell PCell, determining the size of a second data volume needing to be forwarded by an RLC layer of the primary cell PCell to the secondary cell SCell, wherein the primary cell PCell and the secondary cell SCell belong to different base stations; determining a preset size of each RLC PDU, needing to the forwarded to the secondary cell SCell, of the primary cell PCell; based on the size of the second data volume and the preset size of each RLC PDU, obtaining M RLC PDUs, needing to the forwarded to the secondary cell, of the primary cell PCell; and transmitting the M RLC PDUs to the RLC layer at the SCell side through an X2 port in a periodic or event manner.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a device for obtaining and sending data. Background technique [0002] In an LTE (Long Term Evolution, long-term evolution) system, a serving cell is a cell that provides a data transmission service for a UE, and each UE has at most one serving cell. After Rel-10 introduces CA (Carrier Aggregation, Carrier Aggregation) technology, UE can have multiple serving cells at the same time, that is, the system aggregates two or more available carriers together to form a larger transmission bandwidth. High transmission rate provides users with a better service experience. Therefore, the cells serving the UE are divided into two categories: PCell / PCC (Primary Cell / Primary Component Carrier, primary serving cell / primary component carrier) and SCell / SCC (Secondary Cell / Secondary Component Carrier, secondary serving cell / secondary member Carrier)). Among them, the PCell inherits the ...
