A virtual antenna mapping method and network device

Abstract

The embodiment of the present application discloses a virtual antenna mapping method and network device: first, a signal is received through a logical port, and the cell load of the corresponding cell is determined, then the corresponding virtual antenna mapping relationship is further determined according to the cell load, and finally, based on The virtual antenna mapping relationship maps signals from logical ports to physical antenna ports for transmission. In this embodiment of the present application, a virtual antenna mapping relationship that maximizes the capacity gain of the network capacity can be dynamically determined in real time according to different cell loads, so that the capacity gain is optimal no matter what cell load is used. .

Description

technical field [0001] The present application relates to the field of communications, and in particular, to a virtual antenna mapping method and network device. Background technique [0002] With the development of Long Term Evolution (Long Term Evolution, LTE) network construction, how to better meet user requirements and improve user experience has become the focus of mobile network construction. However, with the growth of LTE users and the further improvement of business volume, for scenarios with limited air interface such as Physical Resource Block (PRB) resources, LTE networks often need to be expanded to increase network capacity to meet more users and more business volume needs. [0003] At present, the way to expand the LTE network is generally to use the Four Transmitter For Six Sectors (4T6S) technology, which can effectively increase the capacity of a single station and a region, and is one of the effective ways to improve the network capacity. 4T6S solutions...

Problems solved by technology

[0004] However, the capacity gain of the 4T6S solution is affected by the load of the cell: when the load of the cell is higher, the capacity gain is greater, which means that the throughput of the cell is higher and the corresponding network capacity is larger; When the cell load is low, due to the influence of inter-sector interference, the capacity gain is small, and even the capacity gain is better than the traditional Four Transmitter Four Receiver (4T4R) scheme or the virtual four-antenna transmission and four-antenna reception ( Virtual Four Transmitter Four Receiver, V4T4R) scheme is still low

And the lower the cell load, the smaller the capacity gain. That is to say, although the 4T6S solution can increase the network capacity by increasing the capacity gain, the capacity gain is seriously affected by the cell load.
