Problems solved by technology

[0004] In the process of MeNB allocating downlink data, if the amount of data allocated to the distribution node is too much, it may cause congestion of data packets at the distribution node, resulting in increased packet delay or even packet loss
Conversely, if the amount of data allocated to the distribution node is too small, it may lead to waste of resources and no gain

Embodiment Construction

[0138] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0139] combine figure 1 , exemplarily describes a dual-link network scenario, the user equipment UE is within the service range of the base station and the distribution node at the same time, and can receive data through the distribution node and the base station.

[0140] It should be noted that, the base station is usually a macro evolved base station MeNB, and the offloading node may be a small evolved base station (English: Small cell evolved Node B, SeNB for s...

Abstract

Provided are a method for sending data and a base station, so that when the base station distributes data to an offload node, the data can be distributed more reasonably to the offload node and at the same time, the throughput of a UE is increased. The method comprises: a base station acquires a backhaul link time between the base station and the offload node; the base station determines to send a first volume of data within the backhaul link time; the base station distributes a second volume of data and a third volume of data to the base station and the offload node respectively, wherein a sum of the second volume and the third volume is a difference value between a volume of data to be sent to a user equipment (UE) and the first volume of data; the base station sends the third volume of data to the offload node; and the base station sends the first volume of data and the second volume of data to the UE. The method is applicable to the technical field of communications.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data sending method and a base station. Background technique [0002] In order to improve the throughput of the network system and increase the data transmission rate, a new type of network scenario is proposed in the prior art, such as figure 1 As shown, in this network scenario, for the data carried by the same UE, all or part of the data can be transmitted to the user equipment (English: User Equipment, referred to as: UE), or all or part of the data can be transmitted to the user equipment through the distribution node, that is, the user equipment can be served by the macro cell served by the macro-evolved base station and the small cell served by the distribution node at the same time, and the UE has dual Link. Compared with the same bearer being only established on one evolved base station (English: evolved Node B, eNB for short), this improves the data t...
