Channel estimation enhancements

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