    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.

    摘要： An apparatus and method for selecting a beam group and a subset of beams in a communication system are disclosed. The method includes: measuring channel state information (CSI) on a downlink from a base station (920); identifying a selected beam group out of a set of beam groups according to a wideband property of the CSI (930); identifying a selected subset of beams in the selected beam group according to at least one subband (940). Wherein the characteristic of the set of beam groups depends on a transmission rank and the number of beams in the selected subset of beams is equal to the transmission rank. The method further includes: generating encoded feedback information identifying the selected beam group and the selected subset of beams for each subband in a double codebook format (950), transmitting the encoded feedback information to the base station. A computer program product comprising the computer program code which is configured to cause the apparatus to implement above operations is also disclosed.

    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 user equipment UE determines at least one first set SI of physical resource blocks PRBs, and detects downlink signaling within search spaces of set(s) SI. Through that downlink signaling the UE obtains a configuration for a downlink control channel, and that configuration indicates at least one second set S2 of PRBs and at least one search space specific for the UE which lies within S2. The UE utilizes the obtained configuration to monitor at least some of the search spaces of SI and the at least one search space specific for the UE of S2 for further downlink control signaling. Multiple implementations are detailed for how the UE gets SI. This invention is particularly useful for a configurable ePDCCH region in a stand-alone carrier where the UE is not able to get the new configuration from some other carrier such as a PCell whose configuration does not change.
