Abstract
Systems, devices, apparatuses, and methods, including computer programs encoded on storage media, define beam measurement and reporting enabling to predict best beams using an ML model. A UE (102) receives (308), from a network entity (104), a configuration for a measurement report using a beam quality quantization procedure. The measurement report corresponds to at least one of: a CSI report, an L1-RSRP report, or an L1-SINR report that are each based on a beam measurement that uses one or more CSI-RSs as a CMR. The UE (102) receives (312), from the network entity (104), the one or more CSI-RSs for the beam measurement and transmits (316), to the network entity (104), the measurement report. The measurement report is based on the beam measurement and the beam quality quantization procedure.
Claims20
A method of wireless communication at a user equipment (UE), comprising:
- receiving, from a network entity, a configuration for a measurement report using a beam quality quantization procedure, the measurement report comprising at least one of:
- a channel state information (CSI) report,
- a layer 1 reference signal received power (L1-RSRP) report, or
- a layer 1 signal-to-interference plus noise ratio (L1-SINR) report that are each based on a beam measurement that uses one or more channel state information-reference signals (CSI-RSs);
- receiving, from the network entity, the one or more CSI-RSs for the beam measurement;
- and
- transmitting, to the network entity, the measurement report, the measurement report being-based on the beam measurement and the beam quality quantization procedure.
A method of wireless communication at a network entity, comprising:
- transmitting, to a user equipment (UE), a configuration for a measurement report that uses a beam quality quantization procedure, the configuration directing the UE to include, in the measurement report, at least one of:
- a channel state information (CSI) report,
- a layer 1 reference signal received power (L1-RSRP) report, or
- a layer 1 signal-to-interference plus noise ratio (L1-SINR) report that are each based on one or more channel state information-reference signals (CSI-RSs);
- transmitting, to the UE, the one or more CSI-RSs;
- and
- receiving, from the UE, the measurement report, the measurement report based on the beam quality quantization procedure and the one or more CSI-RSs.
An apparatus for wireless communication comprising:
- a transceiver;
- a memory;
- and
- a processor coupled to the memory and the transceiver, the apparatus-being processor being configured to:
- receive, from a network entity, a configuration for a measurement report using a beam quality quantization procedure, the measurement report comprising at least one of:
- a channel state information (CSI) report,
- a layer 1 reference signal received power (L1-RSRP) report, or
- a layer 1 signal-to-interference plus noise ratio (L1-SINR) report that are each based on a beam measurement that uses one or more channel state information-reference signals (CSI-RSs);
- receive, from the network entity, the one or more CSI-RSs for the beam measurement;
- and
- transmit, to the network entity, the measurement report, the measurement report based on the beam measurement and the beam quality quantization procedure.
