Handling mismatch of control spans between serving cell and interfering cells for control and data channel interference cancellation

摘要

The following is directed to control and data channel interference cancellation between a serving cell and interfering cell. A first symbol of a subframe is processed to determine a control span of a serving cell and a control span of an interfering cell. The interference is then cancelled based on the determined control spans.

主权项

1. A method of wireless communication, comprising:
processing, at a user equipment (UE), a first symbol of a subframe of an interfering cell to determine a control span of the interfering cell, the first symbol processed by decoding a physical control format indicator channel (PCFICH) of the interfering cell; estimating a traffic to pilot ratio for resource element groups in the first symbol; performing control channel interference cancellation for resource element groups in the first symbol based on the estimated traffic to pilot ratio; and performing interference cancellation for at least one of a remaining control symbol, a data channel, or a combination thereof, based at least in part on a difference between the control span of the interfering cell and a control span of a serving cell.
