Abstract
In accordance with particular embodiments, there is disclosed herein a method performed by a wireless device for measurement reporting. The method includes detecting a first number of beams. The method also includes measuring one or more characteristics of a second number of beams. The second number of beams comprises one or more beams of the first number of beams. The method additionally includes generating a measurement report that includes beam measurement information derived from the measurement of the one or more characteristics of the second number of beams. The method further includes transmitting the measurement report with the beam measurement information to a network node.
Claims16
A method for measurement reporting comprising:
- generating at a network node a message comprising a beam reporting configuration specifying how a wireless device is to construct a measurement report;
- receiving at the wireless device the message comprising the beam reporting configuration;
- measuring, at the wireless device, one or more characteristics of a first number of beams;
- generating, at the wireless device, layer 1 cell quality value by processing at least some of the one or more characteristics;
- upon the beam reporting configuration specifying only layer 1 processing:
- generating, at the wireless device, a measurement report comprising the cell quality value;
- and
- discarding, at the wireless device, the one or more characteristics after layer 1 processing;
- upon the beam reporting configuration specifying layer 3 processing in addition to layer 1 processing:
- selecting, at the wireless device, one or more beams to be included in the measurement report;
- generating, at the wireless device, layer 3 beam measurement information for the selected one or more beams based on at least some of the one or more characteristics;
- and
- generating, at the wireless device, a measurement report comprising the cell quality value and the beam measurement information;
- transmitting to the network node the measurement report;
- receiving, at the network node, the measurement report;
- and
- modifying, at the network node, one or more network configuration parameters based on the received measurement report.
A system for measurement reporting comprising:
- a network node configured to generate a message comprising a beam reporting configuration specifying how a wireless device is to construct a measurement report;
- and
- a wireless device configured to communicate with the network node, wherein the wireless device is further configured to:
- receive the message comprising the beam reporting configuration;
- measure one or more characteristics of a first number of beams;
- generate a layer 1 cell quality value by processing at least some of the one or more characteristics;
- upon the beam reporting configuration specifying only layer 1 processing:
- generate a measurement report comprising the cell quality value;
- and
- discard the one or more characteristics after layer 1 processing;
- upon the beam reporting configuration specifying layer 3 processing in addition to layer 1 processing:
- select one or more beams to be included in the measurement report;
- generate layer 3 beam measurement information for the selected one or more beams based on at least some of the one or more characteristics;
- and
- generate a measurement report comprising the cell quality value and the beam measurement information;
- transmit to the network node the measurement report;
- wherein the network node is further configured to:
- receive the measurement report;
- and
- modify one or more network configuration parameters based on the received measurement report.
