Embodiment 1

[0038] Embodiments of the present invention provide a device type selection method, such as Figure 4 Shown include:

[0039] S101. Obtain the typical channel simulation data under the first mobile communication technology and the historical CQI under the second mobile communication technology in the specified area; wherein, the typical channel simulation data is based on the specified channel model according to the typical scene under the first mobile communication technology The typical scene obtained by the simulation includes at least one of dense urban areas, suburban areas, and open areas.

[0040] It should be noted that in actual applications, when obtaining typical channel simulation data of 5G SINR, it is necessary to perform user point simulation on the same device type under the same typical scenario, the same station height, and the same station distance. Thus, the typical channel simulation data of 5G for this device type can be obtained.

[0041] Exemplarily, ...

Embodiment 2

[0104] An embodiment of the present invention provides an equipment type selection device 10, such as Figure 10 Shown include:

[0105] The obtaining unit 101 is configured to obtain typical channel simulation data under the first mobile communication technology and historical CQI under the second mobile communication technology in a specified area; wherein, the typical channel simulation data is obtained by analyzing typical scenarios under the first mobile communication technology according to The specified channel model is simulated, and typical scenarios include at least one of dense urban areas, suburban areas, and open areas;

[0106] The processing unit 102 is configured to determine the cumulative distribution function of the SINR under the first mobile communication technology according to the typical channel simulation data obtained by the obtaining unit 101;

[0107] The processing unit 102 is further configured to determine the median SINR value of each device ty...

Abstract

Embodiments of the present invention provide a device type selection method and device, which relate to the field of communication technology and solve the problem of how to replace the equipment in the base station area with suitable AAU equipment according to the user requirements in the base station area. The method includes, obtaining typical channel simulation data under the first mobile communication technology and internal historical CQI in a specified area; according to the typical channel simulation data, determining the cumulative distribution function of the SINR; according to the cumulative distribution function, determining the SINR of each equipment type bit value; determine the SINR interval according to the median value of the SINR, and match the SINR interval with the device type to determine the corresponding relationship between the SINR interval and the device type; Target SINR: Determine the type of equipment deployed in the specified area according to the first target SINR and the corresponding relationship.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a device type selection method and device. Background technique [0002] The fifth-generation mobile communication technology (English full name: 5th-generation, abbreviation: 5G), as a brand-new next-generation communication system, has made a comprehensive breakthrough from the equipment level. First, the number of antenna arrays has been changed from long-term evolution (English full name: longterm evolution, 32 for short: LTE) are upgraded to 128 and 192 for new air interfaces (English full name: new radio, abbreviated as: NR). Secondly, if figure 1 The radio frequency remote unit (full name in English: Active Antenna Unit, referred to as: AAU) equipment transmits and receives the number of channels also by LTE 2 transmit (full name in English: transmit, referred to as: T) 2 receive (full name in English: receive, referred to as : R) upgrade to 8T8R, 16T16R, 3...
