Abstract
Facilitating generic feedback to enable reciprocity and over the air calibration for advanced networks (e.g., 4G, 5G, and beyond) is provided herein. Operations of a system can comprise selecting information to include in a channel state information feedback report based on a feedback instance. The operations can also comprise generating the channel state information feedback report as a function of channel statistics of channels. Further, the operations can comprise transmitting the channel state information feedback report to a network device of a communications network.
Claims20
A system, comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
- selecting, based on a feedback instance, first information to include in a channel state information feedback report and second information to exclude from the channel state information feedback report;
- generating the channel state information feedback report as a function of channel statistics of channels and based on facilitating over-the-air calibration at a network device of a communications network without additional feedback overhead for different groups of antennas;
- and
- transmitting the channel state information feedback report to the network device of a communications network, wherein the channel state information feedback report is an on-demand channel state information feedback report.
A method, comprising:
- selecting, by a mobile device comprising a processor, channel state information for inclusion in a feedback report based on a request for the feedback report, wherein the request is received from a network device of a communications network, and wherein the channel state information is selected based on conditions at the mobile device at a time when the request was received;
- generating, by the mobile device, the feedback report with selected channel state information selected based on facilitating over-the-air calibration at the network device without additional feedback overhead for different groups of antennas;
- and
- facilitating, by the mobile device, transmitting the feedback report to the network device in response to the request.
A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
- based on a request for a report received from a network device of a communications network, selecting a format for the report based on mitigation of feedback overhead, wherein content of the report is not preconfigured, and wherein the report comprises channel state information;
- defining a feedback container to send to the network device, wherein the feedback container carries the channel state information, and wherein the content of the feedback container changes based on the content of the report;
- generating the report based on channel statistics currently available and the feedback container, and based on facilitating over-the-air calibration at the network device without additional feedback overhead for different groups of antennas;
- and
- sending the report to the network device in response to the request.
