Problems solved by technology

In a large-scale antenna system, due to the large number of multiplexed users at the same time, according to the current standard, a large number of control signaling PDCCHs are required, which consumes a lot of resources and seriously affects resource utilization efficiency.
1 PDCCH can be composed of 1/2/4/8 CCEs, and each CCE occupies 36 REs. Assume that 1 PDC

Abstract

The invention discloses a control signaling transmission method of a large-scale antenna system, a base station, a terminal and a system. The method comprises the steps that user terminals in an activation state are divided into one or more user terminal groups, and user terminals in each user terminal group is numbered; when control signaling is sent, a group of physical downlink control channel G-PDCCH signaling is sent to each user terminal group, wherein the G-PDCCH signaling comprises user terminal grouping index, user terminal scheduling instruction and user terminal scheduling information. According to the control signaling transmission method of the large-scale antenna system, the base station, the terminal and the system, the overhead of control signaling can be significantly reduced; the consumption of resources is reduced; and the utilization rate of resources is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method for sending control signaling of a large-scale antenna system, a base station, a terminal and a system. Background technique [0002] With the rapid development of mobile communication technology, it is estimated that by 2020, mobile data traffic will increase by 500-1000 times compared to 2010. The 5G system needs to increase the network capacity accordingly to meet the explosive growth demand of data services. High-bandwidth applications such as ultra-high-definition video, video conferencing, massive data sharing, and 3D games place higher demands on communication rates. The 5G system needs to support higher data rates to support future large-bandwidth services, and provide and guarantee a higher and fairer rate experience for each user in the network. Higher efficiency: Future networks will face conflicts between a surge in capacity demand and a...
