    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 network access node selects one chunk of spectrum from a plurality of chunks of spectrum to be a primary chunk for a particular cell; transmits in the primary chunk from a broadcast channel BCH that contains information needed by a terminal to at least perform initial cell access; and uses a synchronization channel SCH to indicate which chunk of the plurality of chunks is the primary chunk. A user equipment receives a SCH in a particular chunk of spectrum; determines from it that one chunk is a primary chunk for a particular cell; tunes its receiver to a BCH in the primary chunk and uses information received on the BCH to obtain initial access to the particular cell. In various embodiments the SCH is only in the primary chunk or the SCH has some indication (e.g., cell ID or relative position of primary chunk) telling which chunk is primary.

    摘要： A first precoding matrix W1 is selected from a first codebook comprising sets of rank specific precoding matrices. The first codebook is characterized by there being fewer precoding matrices associated with higher ranks than associated with lower ranks, and characterized by precoding matrices associated with ranks above a certain rank all being diagonal matrices. The selected first precoding matrix W1 is used to select a rank-specific second precoding matrix W2 from a second codebook, such that the selected first and second precoding matrices form a joint precoder specific to a desired rank. The second codebook is characterized by differently sized precoding matrices associated with each of N total ranks, in which N is an integer greater than one. Information on the joint precoder is reported to a network node over an uplink transmission channel.
