    摘要: 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.

    摘要: A method, apparatus and computer program product are provided for reporting low rank feedback information for each transmission point up to a maximum rank per transmission point. In this regard, a method includes determining a transmission rank and a precoding matrix for each of at least two transmission points of a plurality of transmission points. A method also includes determining a joint transmission rank based on at least two of the plurality of transmission points. A method also includes selecting a joint transmission precoding matrix based on the determined precoding matrix for each of the at least two transmission points and the determined joint transmission rank. The method further includes causing channel state information “CSI” to be transmitted to an access point, wherein the CSI describes the selected joint transmission precoding matrix.

    摘要: Examples are described relating to methods, apparatus and computer programs for configuring a user equipment in a cellular wireless network. Certain exemplary methods involve receiving (440), at the user equipment (430), control information regarding one or more of a plurality of channel-state information (CSI) reference signals. The plurality of CSI reference signals are receivable by the user equipment (430) from one or more of a plurality of antenna ports that form part of the cellular wireless network, the plurality of CSI reference signal being associated with corresponding antenna ports. The control information is for use in configuration of the user equipment (430) and is received over a radio communications downlink from a node (410) in the cellular wireless network. If estimation of one or more radio communication channels at the user equipment (430) is configured (450) based on the received control information, improvements in demodulation and CSI feedback are achieved.
