Channel estimation in wireless networks

摘要

Aspects of the present disclosure generally relate to wireless communications and, more particularly, to performing channel estimation with modifications for improved system performance. Aspects generally include receiving, at a user equipment (UE), reference signals from a base station in a current subframe, and performing channel estimation, wherein the channel estimation is based at least in part on the reference signals received in the current subframe, a mobility characteristic of the UE, and a configuration of subframes prior to the current subframe.

主权项

1. A method for wireless communications, comprising:
receiving, at a user equipment (UE), reference signals from a base station in a current subframe; and performing channel estimation, wherein the channel estimation is based at least in part on the reference signals received in the current subframe, a Doppler estimation of the UE, and a configuration of subframes prior to the current subframe, wherein the Doppler estimation is adjusted based at least in part on a number of subframes prior to the current subframe in which transmission of downlink reference signals is limited or non-existent.
