Virtual antenna mapping method and network equipment

Abstract

The embodiment of the application discloses a virtual antenna mapping method and network equipment. The virtual antenna mapping method comprises: firstly, receiving a signal through a logic port, determining a cell load of a corresponding cell, then further determining a corresponding virtual antenna mapping relation according to the cell load, and finally, based on the virtual antenna mapping relationship, mapping a signal from a logic port to a physical antenna port for transmission. In the embodiment of the invention, the virtual antenna mapping relation which enables the capacity gain of the network capacity to be maximum can be dynamically determined in real time according to different cell loads, so that the capacity gain is optimal under any cell load.

Description

technical field [0001] The present application relates to the communication field, in particular to a virtual antenna mapping method and network equipment. Background technique [0002] With the development of long-term evolution (Long Term Evolution, LTE) network construction, how to better meet user needs and improve user experience has become the focus of mobile network construction. However, with the growth of LTE users and further increase in business volume, for scenarios where air interfaces such as Physical Resource Block (PRB) resources are limited, 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 capacity of LTE network is generally to adopt Four Transmitter For Six Sectors (4T6S) technology, which can effectively increase the capacity of single station and area, and is one of the effective ways to improve network capacity. 4T6S solutions include analo...

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.
