Device and Method for Adaptive Channel Estimation

A method comprising:

• receiving a Multicast-Broadcast Single-Frequency Network (MBSFN) subframe, the MBSFN subframe having a MBSFN subframe structure including a plurality of Orthogonal Frequency-Division Multiplexing (OFDM) symbols, a first one of the OFDM symbols having a first reference symbol inserted therein, a second one of the OFDM symbols having a second reference symbol inserted therein;
• and
• performing a non-destaggered channel estimation when a rate of change of channel conditions is greater than a predetermined threshold, the non-destaggered channel estimation using a first Channel Impulse Response (CIR) at the first OFDM symbol and a second CIR at the second OFDM symbol.

An integrated circuit, comprising:

• circuitry to receive a subframe from a base station of the access network, the subframe including a plurality of symbols, a first one of the symbols having a first reference symbol inserted therein, a second one of the symbols having a second reference symbol inserted therein;
• and
• circuitry to perform a non-destaggered channel estimation when a rate of change of channel conditions is greater than a predetermined threshold, the non-destaggered channel estimation using a first Channel Impulse Response (CIR) at the first symbol and a second CIR at the second symbol.
