Abstract
Methods, apparatus and computer program products provide channel state information (CS1) measurement and reporting for a segment carrier in certain situations. An apparatus such as a base station may determine whether CSI is needed for a channel of a segment carrier comprising a segment portion and a contiguous bandwidth extension of a backward compatible carrier utilized by a base station for wireless communications with a mobile terminal. In response to determining that CSI is needed, the apparatus configures the mobile terminal to communicate channel state information from the mobile terminal to the base station. In other embodiments, an apparatus such as a mobile terminal is configured to receive configuration data indicating whether CSI is to be measured by the mobile terminal, and measuring the CSI and communicating the CSI to the base station in response to the configuration data.
