摘要
Techniques for dynamically allocating frequency resources in accordance with wireless access technologies are discussed herein. For example, a base station can determine whether user equipment (UE) requesting communications at the base station are configured to operate in accordance with 4th Generation (5G) radio access technologies and/or in accordance with 5th Generation (5G) radio access technologies. Based on the number of 5G UEs and 4G UEs, a first portion of a frequency resource can be allocated to 5G and a second portion of the frequency resource can be allocated to 4G. In some examples, a first allocation strategy for a first frequency resource (e.g., Band 71) can be used to generate a second allocation strategy for a partially overlapping second frequency resource (e.g., Band 41).

Traditionally, service providers have obtained licenses to conduct wireless communications in a particular range of frequencies, and accordingly, have programmed base stations in a wireless network to use a fixed set of frequency resources. However, numbers of user devices have grown over time, greatly increasing an amount of wireless traffic to be handled by the wireless networks.
In some cases, frequency resources can be utilized in accordance with different radio access technologies. Long-Term Evolution (LTE) is an example of a widely implemented radio access technology that is used in 4th-Generation (4G) communication systems. New Radio (NR) is a newer radio access technology that is used in 5th-Generation (5G) communication systems. Standards for LTE and NR radio access technologies have been developed by the 3rd-Generation Partnership Project (3GPP) for use within cellular communication networks by wireless communication carriers. Note that the terms 4G and LTE are often used interchangeably when referencing certain 4G systems and components. Also, NR radio access technology may at times be referred to as 5G radio access technology. That is, the terms NR and 5G can also be used interchangeably when referencing certain 5G systems and components.
Devices that can communicate in accordance with 5G radio access technologies can often communicate in accordance with 4G radio access technologies. However, legacy devices configured in accordance with 4G radio access technologies often are not compatible with 5G radio access technologies. Accordingly, a portion of a frequency resource must often be dedicated to providing service to 4G devices, which can reduce an availability of resources for devices configured in accordance with 5G radio access technologies.
