Problems solved by technology

[0003] Unicast refers to the establishment of a separate information transmission path between the sending end and the receiving end. There is a "one-to-one" communication mode between the sending end and the receiving end. When multiple receiving ends need to receive the same business data, the sending end needs to Sending one by one, sending data streams for each receiving end, it is easy to cause network congestion and waste resources

Abstract

The invention provides a data transmission method and device in a wireless communication system, and the method comprises the steps: carrying out media stream receiving group division on all terminals served by a base station, wherein the media stream receiving groups are all terminals which are served by the base station and need to receive the same media data stream; dynamically monitoring the terminal number of the media stream receiving group, adjusting a data sending mode in real time according to the terminal number of the media stream receiving group, and dynamically selecting to use a broadcast mode or a unicast mode to transmit downlink data. Through the data transmission method and device provided by the invention, the bandwidth can be saved, the efficiency can be improved, and efficient wireless communication can be realized.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for data transmission in a wireless communication system. Background technique [0002] The rapid development of wireless communication technology and mobile multimedia services has sharply increased the demand for wireless resources. Traditional broadcasting system scenarios need to implement two-way links to meet the needs of end users. With the rapid growth of multimedia services, the load on mobile networks is increasing day by day. , limited air interface resources need to carry a huge amount of data. [0003] Unicast refers to the establishment of a separate information transmission path between the sending end and the receiving end. There is a "one-to-one" communication mode between the sending end and the receiving end. When multiple receiving ends need to receive the same business data, the sending end needs to Sending one by o...
