Abstract
A system can collect respective measurements from respective user equipment that are in communication with a cell of a broadband cellular network. The system can determine a group of precoding matrices based on the respective measurements. The system can, before a user equipment attaching to the cell, select a precoding matrix from the group of precoding matrices for initial downlink transmission with the user equipment. The system can communicate with the user equipment based on the precoding matrix.
Claims20
A system, 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:
- collecting respective measurements from respective user equipment that are in communication with a cell of a broadband cellular network;
- determining a group of precoding matrices based on the respective measurements;
- before a user equipment attaching to the cell, selecting a precoding matrix from the group of precoding matrices for initial downlink transmission with the user equipment;
- and
- communicating with the user equipment based on the precoding matrix.
A method, comprising:
- collecting, by a system comprising at least one processor, respective measurements from respective user equipment that are in communication with a cell of a broadband cellular network;
- determining, by the system, a group of precoding matrices based on the respective measurements;
- before a user equipment attaches to the cell, selecting a precoding matrix from the group of precoding matrices;
- and
- based on the user equipment being determined to have attached to the cell, communicating with the user equipment using the precoding matrix.
A non-transitory computer-readable medium comprising instructions that, in response to execution, cause a system comprising at least one processor to perform operations, comprising:
- collecting respective measurements from respective devices that are in communication with a cell of a broadband cellular network;
- determining a group of precoding matrices based on the respective measurements;
- and
- communicating with a device for initial downlink transmission using a precoding matrix that is selected from the group of precoding matrices before the device attaches to the system.
