Abstract
The present disclosure provides methods and apparatuses for performing channel estimation in a wireless environment using a Primary Physical Common Control Channel (P-CCPCH) to aid in channel estimation. For example, according to an example method provided by the present disclosure, a user equipment (UE) may receive a pilot signal and a Primary Physical Common Control Channel (P-CCPCH) signal from a network entity. In an aspect, the P-CCPCH signal may include initial broadcast channel (BCH) data layered thereon. Furthermore, the UE may predict estimated P-CCPCH data based on the initial BCH data. Additionally, in an aspect, the UE may estimate a channel based on at least the estimated P-CCPCH data and the pilot signal. As such, more reliable channel estimation is possible in wireless systems, such as at UE locations at the geographical periphery of a network entity serving area.
