1. A user equipment (UE) for wireless communication, comprising:
- a communication interface configured to receive an indication of a traffic-to-pilot ratio (TPR) for demodulation reference signals (DMRSs) from a base station based on at least a rate associated with the UE; and
a processing circuit coupled to the communication interface and configured to process one or more pilots received from the base station based on at least the TPR.

Abstract
The disclosure relates in some aspects to techniques for improved channel estimation. For example, a device can specify a pilot structure where pilot density differs over time. As another example, a device can indicate that a pilot from a prior transmission time interval (TTI) can be used for channel estimation. As another example, a device can employ frequency domain physical resource block (PRB) bundling with the bundling information signaling. As yet another example, a device can use an adjustable traffic-to-pilot ratio (TPR) for throughput optimization. Other aspects, embodiments, and features are also discussed and claimed.
