    摘要： Communications may be performed in a communications system using multi-dimensional antenna configurations. A WTRU may receive communications from a base station via one or more channels. The communications may be performed using multiple component codebooks. The WTRU may send channel state information (CSI) feedback for each component codebook to the base station for consideration when performing communications with the WTRU. The WTRU may determine the CSI feedback for each component codebook based on channel measurements. The component codebooks may include a horizontal component codebook and/or a vertical component codebook. The WTRU may send the CSI feedback for each component codebook to the base station independently or in the form of a composite codebook. The WTRU may determine a composite codebook a function of the component codebooks.

    摘要： Systems, methods, and instrumentalities are disclosed for downlink resource allocation associated with a shared frequency band. A WTRU may receive resource allocation information associated with a component carrier and at least one carrier segment. The component carrier and the least one carrier segment may each comprise a plurality of resource block groups (RBG). At least two bitmaps may be associated with the resource allocation information. A size of a resource block group (RBG) of the component carrier and the at least one carrier segment may be based on a combined number of resource blocks (RB) of the component carrier and the one or more carrier segments divided by a 3GPP Rel-8/Rel-10 RBG size of the component carrier. The WTRU may determine at least one RBG allocated to the WTRU using the resource allocation information and may receive and decode the at least one RBG allocated to the WTRU.

    摘要： Reference signals configured for use with extension carriers and/or carrier segments are described. Reference signals for extension carriers and/or carrier segments may include demodulation reference signals (e.g., user equipment-specific reference signals), cell-specific reference signals, and channel-state information reference signals. Methods, systems and apparatuses for configuring extension carriers and/or carrier segments with one or more of the reference signals (e.g., positioning one or more reference signal symbols in extension carriers and/or carrier segments) are described.

    摘要： ePDCCH may be provided. For example, a WTRU may receive a configuration for monitoring an ePDCCH resource. Based on the configuration, the WTRU may be configured to monitor and may monitor the ePDCCH resource on a particular subframe. Additionally, a WTRU may derive an aggregation level for a subframe associated with an aggregation level number NAL. The WTRU may transmit or monitor an ePDCCH using the aggregation level associated with the NAL for the subframe. A WTRU may also receive a reference signal. The WTRU may then determine the type of reference signal received. The WTRU may perform a demodulation of the PDSCH or ePDCCH using a demodulation timing based on the determined type. The ePDCCH or PDSCH may also be monitored or received by identifying a demodulation reference timing implicitly based on a location of one or more ePDCCH resources where the WTRU may receive DCI.
