摘要： A network sends to a user equipment UE a reference signal configuration, and from receiving it the UE selects a codeword identifying a cooperative multipoint CoMP transmission scheme. There is a CoMP scheme selection codebook from which the UE selects the codeword corresponding to its recommended CoMP scheme. The UE sends to the network that codeword which identifies the CoMP transmission scheme, along with the CSI feedback characterizing the CoMP transmission scheme. From that codeword which the network receives it determines the UE's assumed CoMP transmission scheme, which the network uses to determine how the CSI feedback, received from the UE, was calculated by the UE (for example, joint transmission, or dynamic point selection with or without muting, or coordinating scheduling/beamforming). The network uses this information for selecting a CoMP transmission scheme for downlink CoMP transmissions to the UE.

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： There is provided a mechanism providing a flexible feedback framework operating in different scenarios, such as heterogeneous network deployments. Antenna information are sent from a scheduler element to a UE, the antenna information including information indicating a grouping of one or more antenna in closely spaced antenna groups of one or more transmit points. The UE selects at least one of precoding codewords and amplitude weight parameters for each closely spaced antenna group, and determines information related to a sub-band precoder and a transmit point related combiner. The processing results are indicated to the scheduler by means of sending indices related to a wide-band long-term precoder and a sub-band short-term precoder. The scheduler processes these results for determining a joint precoder.

摘要： Structure of a multi-carrier flexible spectrum wireless cell is determined from received synchronization or broadcast channels of detected individual carriers. The determined structure is used to select an intended carrier for initial access or cell reselection to the flexible spectrum wireless cell. The structure may have carriers compatible with an earlier version (LTE/Release 8) of a communication standard and with a later version (LTE-A/Release 9). The received synchronization channels can inform of: relative positions of the individual carriers in a spectrum band of the multi-carrier structure; relative timing alignments of the received synchronization channels; contents of the received synchronization channels; and/or layer 1 cell-carrier identifiers. The synchronization channels may have a different structure as between the earlier and later versions, and the different structure is used to select the carrier that is compatible with the user equipment making the selection.
