- the network entity may transmit multiple ML models, or indications of the multiple ML models, to the UE, and the UE may select an ML model from among the multiple ML models based at least in part on a selection rule.
- the selection rule may involve, for example, a battery level of the UE, an indication from a network entity, or a selection algorithm.
- the UE may then use the ML model to predict a beam.
- the UE may subsequently select and use the predicted beam for communication.

For example, using an ML model associated with one or more capabilities of a UE for beam prediction may enable quicker beam selection. Beam selection by beam prediction may be quicker than beam selection involving multiple beam measurements. Furthermore, using the ML model associated with the one or more capabilities of the UE may enable more efficient use of UE resources for beam selection, because the ML model may be selected to utilize UE resources without straining the UE resources.

- FIG. 6 is a diagram illustrating an example of beam prediction at a UE, in accordance with the present disclosure.
- a network entity may configure a UE (for example, the UE 120) with an ML model configuration to execute ML models at the UE 120.

- the UE 120 may use an ML model to predict a beam to use for communication
- the UE 120 may be configured with an ML model that has too much or not enough complexity for the UE 120. For example, if an ML model involves too many computations for the processing capability of the UE 120, the UE 120 may not be able to obtain a beam prediction in a reasonable amount of time. As a result, latency is introduced and the beam selection may be suboptimal. This may waste battery power, processing resources and signaling resources.

- the UE 120 may use the ML model to predict a beam.
- the UE 120 may select and use the beam for communication.
- the described techniques can be used to reduce latency, conserve power at the UE 120, and improve beam selection. Quicker and more accurate beam selection improves communications and conserves processing resources and signaling resources.

- an output of an ML model may be a beam ID for a preferred beam (for example, a beam with a greatest signal strength) at a future time or other related metrics at a future time.
- a preferred beam for example, a beam with a greatest signal strength
- the UE 120 may conserve reference signal resources because reference signals are transmitted less frequently for beam tracking and channel estimation.

- the FC layer neural network (24, 96) may be followed by a rectified linear unit (ReLU) function, an FC layer (96, 48) , and a softmax layer to output a predicted probability distribution of the preferred narrow refined beam ID.
- the parameter size may be (25 ⁇ 96) + (97 ⁇ 48) , which is about 7000 parameters.
- the multiplication before the softmax layer may be (24 ⁇ 96) + (96 ⁇ 48) , or a little less than 7000 parameters. There may be additional computations due to the ReLU function.
- an ML model may be a convolutional neural network (CNN) that uses convolution layers.
- a convolution layer may perform the function of pattern detection.
- An FC layer neural network may perform classification by combining different types of patterns detected by convolution layers.
- a CNN may be a convolution transposition (for example, with 10 channels and 4 kernels) that uses an ReLU function for a matrix transpose and a convolution (for example, with 48 channels and 10 kernels) with a softmax output layer.
- Some ML models may have fewer parameters but with less effective performance. Other models may have better performance but with a larger parameter size. Another factor may be the computational complexity during the inference determination or the online training. Even for the same ML model, when implemented at the UE 120, the trained parameter set and the model structure may be modified for better inference efficiency at the UE 120.
- parameters may be quantized with different bit widths or pruned. Some parameters in dense connected NNs may be omitted in inference. Different levels of quantization or pruning may lead to different performance degradations. Therefore, by selecting ML models based at least in part on the UE capabilities, ML model performance and beam prediction improve.
