Abstract
Architectures and techniques are provided for intelligently selecting a modulation coding scheme (MCS) table that is to be used for a connection between an access point (e.g., a distributed unit) and a user equipment (UE). Based on an initial signal-to-noise ratio (SNR) value between the access point and UE and data points determined from previous connections involving the access point or a given cell of the access point an adaptive access point-specific SNR threshold can be determined. This SNR threshold can evolve over time based on the collected data and can be used to choose a particular MCS table for subsequent connections.
Claims20
A device, comprising:
- at least one processor;
- and
- at least one memory that stores executable instructions that, when executed by the at least one processor, facilitate performance of operations, comprising:
- in response to a user equipment (UE) connecting to a distributed unit (DU) for wireless service, determining an initial signal-to-noise ratio (SNR) value for a connection between the UE and the DU;
- comparing the initial SNR value to an adaptive SNR threshold value that is determined as a function of previous connections involving the DU;
- in response to the initial SNR value being determined to be less than the adaptive SNR threshold value, selecting a first modulation coding scheme (MCS) table to be used for the connection between the DU and the UE;
- and
- in response to the initial SNR value being determined to be greater than or equal to the adaptive SNR threshold value, selecting a second MCS table, different than the first MCS table, to be used for the connection between the DU and the UE.
A method, comprising:
- in response to a user equipment (UE) connecting to a distributed unit (DU) for wireless service, determining, by a device comprising at least one processor, an initial signal-to-noise ratio (SNR) value that exists for a connection between the UE and the DU;
- comparing, by the device, the initial SNR value to an adjustable SNR threshold value that is determined as a function of previous connections involving the DU;
- in response to the initial SNR value being less or equal to than the configurable SNR threshold value, choosing, by the device, a first modulation coding scheme (MCS) table to be used for the connection between the DU and the UE;
- and
- in response to the initial SNR value being greater than the configurable SNR threshold value, choosing, by the device, a second MCS table, different than the first MCS table, to be used for the connection between the DU and the UE.
A non-transitory computer-readable medium comprising instructions that, in response to execution, cause a system comprising a processor to perform operations, comprising:
- in response to a user equipment (UE) connecting to a distributed unit (DU) for wireless service, determining an initial signal-to-noise ratio (SNR) value that exists for a connection between the UE and the DU;
- comparing the initial SNR value to an adaptive SNR threshold value that is determined as a function of previous connections involving the DU;
- in response to the initial SNR value being less than the adaptive SNR threshold value, selecting a first modulation coding scheme (MCS) table to be used for the connection between the DU and the UE;
- and
- in response to the initial SNR value being greater than the adaptive SNR threshold value, selecting a second MCS table, different than the first MCS table, to be used for the connection between the DU and the UE.
