Description

Network capacity expansion method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a network capacity expansion method and device.

Background

The network capacity expansion is an important measurement index of a newly built base station, and the network capacity expansion criterion is accurate and reasonable, so that the network construction can be effectively guided, and the user perception reduction caused by untimely capacity expansion can be avoided. At present, a large-scale antenna technology (Massive MIMO) is adopted in a 5G network, wireless resources mainly based on network capacity expansion comprise time domain resources and frequency domain resources, and when the 5G network allocates resources for users, the users with service requirements are firstly paired to form a plurality of empty groups. The users included in the same null packet may be spatially separated, i.e., separated by different beams. Thus, different users within the same null packet may use the same time domain resources and frequency domain resources, but the beams are different. Users within different null packets must separate time domain resources from frequency domain resources. In the process of pairing users, the users need to meet certain conditions at the same time to trigger pairing, such as good channel quality, low correlation among users and large data packet, so that the users can be paired more easily.

However, in the prior art, the network capacity expansion is mainly performed based on time domain resources and frequency domain resources, and in this case, the effect of performing the network capacity expansion does not reach the optimal capacity expansion effect. Therefore, the current network capacity expansion scheme has poor effect and low utilization rate of resources.

Detailed Description

The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

In the description of the present invention, "/" means "or" unless otherwise indicated, for example, A/B may mean A or B. "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. Further, "at least one", "a plurality" means two or more. The terms "first," "second," and the like do not limit the number and order of execution, and the terms "first," "second," and the like do not necessarily differ.

The current 5G network adopts a large-scale antenna technology, and the wireless resources not only comprise time domain resources and frequency domain resources, but also comprise abundant airspace resources. For example, the 64TR device 3.5G frequency point 100M bandwidth cell, the corresponding resources include the following frequency domain resources: the number of the uplink and downlink available PRBs is 273; airspace resource: the maximum number of downlink layers of the cell is 16, and the maximum number of uplink layers of the cell is 8; time domain resources: depending on the statistics period, if 1 hour is counted, the time domain is 1 hour. In MU MIMO technology, when allocating resources for users, a 5G network first "pairs" all users with service requirements to form a plurality of null packets. Users under the same null packet may be spatially isolated, i.e., separated by different beams. Thus, different users under the same null packet may use the same time domain resources and frequency domain resources, but the beams are different. Users under different null packets must be separated by time domain resources and frequency domain resources. The user needs to meet certain conditions at the same time to trigger pairing, such as channel quality, correlation, packet size, etc. The users with good channel quality, low correlation among users and large data packet are more easily paired.

Some network management KPI indicators in 5G networks include:

cell uplink/downlink average scheduling layer number: and in the statistical period, the number of layers called by the uplink/downlink average of the cell is calculated. The index counts the number of cell scheduling layers of time domain and frequency domain double average. The statistical formula is:

wherein M is the average scheduling layer number of uplink/downlink of the cell, and P _n For the number of PRBs of N layers occupied by the uplink/downlink traffic channel of the cell, m is the maximum number of layers occupied by the uplink/downlink traffic channel of the cell, N is the total number of PRBs occupied by the uplink/downlink traffic channel of the cell, i.e., n=p ₁ +P ₂ +P ₃ +...+P _n 。

Average occupancy of cell downlink PDSCH PRBs: and in the cell counting period, the ratio of the total occupied number of the cell downlink PDSCH channels PRB of the gNB to the total available number of the cell downlink PDSCH channels PRB.

Average occupancy of cell uplink PUSCH PRB: and in the cell counting period, the ratio of the total occupied number of the gNB cell uplink PUSCH channel PRB to the total available number of the cell uplink PUSCH channel PRB.
