Base station and multicast data transmission processing method

Abstract

Embodiments of the present invention provide a base station and a multicast data sending processing method, wherein the method comprises: obtaining network parameter measurement reports that respectively correspond to multiple user equipments comprising a multicast group and are used for reflecting wireless network communication quality; determining at least one target user equipment among the multiple user equipments according to each of the network parameter measurement reports and sending a notification message to the target user equipment, wherein the notification message is used for instructing the target user equipment to use a feedback channel resource configured for the target user equipment to return feedback information of whether multicast data is successfully received; sending the multicast data to the multiple user equipments comprising the multicast group and receiving the feedback information returned by the target user equipment. The base station and the multicast data sending processing method provided by the embodiments of the present invention implement multicast data receiving feedback at a low feedback channel resource overhead, improving reliability of multicast data transmission.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a base station and a method for sending and processing multicast data. Background technique [0002] The development of mobile broadband applications, especially mobile video, not only meets the multi-service needs of mobile users, but also brings new business opportunities for service providers, and has attracted the attention of the industry. These mobile bandwidth applications require scheduling the same data for multiple User Equipments (UEs for short) at the same time. Compared with general data services, they have the characteristics of large data volume and long duration. [0003] Figure 1a It is a schematic diagram of adopting a unicast scheduling mechanism in the prior art. Such as Figure 1a As shown, in the technical solution using the unicast scheduling mechanism in the prior art, when the base station needs to schedule the same data for multip...

AI Technical Summary

Problems solved by technology

like Figure 1b As shown, in the technical solution using the eMBMS multicast scheduling mechanism in the prior art, when the evolved base station (Evolved Node B, eNodeB for short) sends the same data to multiple UEs on the same resource at the same time, it does not UEs that receive eMBMS multicast data (such as UE1, UE2, UE3, UE4, and UE5) configure feedback channel resources. Therefore, UEs that receive eMBMS multicast data do not feed back the reception status of multicast data to the base station, and the base station cannot know Whether the UE has correctly received the scheduled multicast data

[0005] The reliability of multicast data transmission in the prior art is poor
