Abstract:
Apparatus and methods for channel estimation in a Multimedia Broadcast Multicast Service (MBMS) Single Frequency Network (MBSFN) are disclosed. A representative method includes a wireless communication device receiving multiple frames, each frame including multiple subframes, each subframe including multiple symbols. The wireless communication device determines whether subframes include MBMS data or not. For subframes that include MBMS data, the wireless communication device excludes all or certain symbols of the subframes that include MBMS data from a channel estimation process. The wireless communication device determines whether the subframes include MBMS data based at least in part on a channel impulse response and/or a channel energy response for one or more symbols of the subframes.
