Abstract
Systems, methods, and computer-readable media herein modify the configuration of one or more antenna elements of an antenna array based on signal quality information associated with one or more UE devices. The signal quality information of the UE devices can be analyzed by a base station and the base station can respond to the change in signal quality of the UE devices by modifying one or more antenna elements from a first mapping to a second mapping to improve the quality of transmissions between the UE devices and a base station.
Claims6
A method for dynamically assigning one or more antenna elements of an antenna array, the method comprising:
- transmitting, from a base station, a first set of reference signals using a first set of antenna elements in a first mapping;
- receiving a first message from a user equipment (UE) comprising a signal to interference noise ratio (SINR) value of the first set of reference signals;
- and
- in response to receiving the first message, transmitting, from the base station, a second set of reference signals using a second set of antenna elements in a second mapping, the second mapping being different than the first mapping;
- transmitting a second set of reference signals to the UE using the second set of antenna elements in the second mapping, the second set of antenna elements comprising a greater number antenna elements than the first set of antenna elements;
- and
- receiving, from the UE, a second message indicating that the SINR value of the second set of reference signals is an improvement to the SINR value of the first set of reference signals.
A system for dynamic assignment of one or more antenna elements of an antenna array, the system comprising:
- a plurality of antenna elements;
- and
- one or more computer processing components configured to perform operations comprising:
- transmitting a first set of reference signals to a user equipment (UE) using a first set of antenna elements in a first mapping;
- receiving a first message from the UE comprising a signal to interference noise ratio (SINR) value of the first set of references signals;
- in response to receiving the first message, communicating a radio configuration message to the UE using a second set of antenna elements in a second mapping;
- transmitting a second set of reference signals to the UE using the second set of antenna elements in the second mapping, the second set of antenna elements comprising a greater number antenna elements than the first set of antenna elements;
- and
- receiving, from the UE, a second message indicating that the SINR value of the second set of reference signals is an improvement to the SINR value of the first set of reference signal.
One or more non-transitory computer-readable media having computer-executable instructions embodied thereon that, when executed, perform a method for configuring one or more antenna elements of an antenna array, the method comprising:
- transmitting a first set of reference signals to a user equipment (UE) using a first set of antenna elements in a first mapping;
- receiving a first measurement report from the UE comprising a signal to interference noise ratio (SINR) value of the first set of references signals;
- in response to receiving the first message, communicating a radio configuration message to the UE using a second set of antenna elements in a second mapping;
- transmitting a second set of reference signals to the UE using the second set of antenna elements in the second mapping, the second set of antenna elements comprising a greater number antenna elements than the first set of antenna elements;
- and
- receiving, from the UE, a second message indicating that the SINR value of the second set of reference signals is an improvement to the SINR value of the first set of reference signal.
