    Abstract: A system and a method is disclosed for selecting at least one vertical precoding vector of a three-dimensional Multiple Input Multiple Output (3D-MIMO) configuration based on Channel State Information-Reference Signal (CSI-RS) information that is feedback from a wireless terminal device to an evolved Node B (eNB). The 3D-MIMO CSI-RS process is configured for a plurality of CSI-RS ports in which the plurality of CSI-RS ports that are grouped into a plurality of CSI-RS port groups and in which corresponds to the 3D arrangement of antennas. CSI configuration information for the different CSI-RS port groups can be a time-domain-based CSI-RS process, a frequency-domain-based CSI-RS process, a code-domain-based CSI-RS process, or a combination thereof. CSI-RS information is measured for each CSI-RS group and feedback for selection of the at least one vertical precoding vector.

    Abstract: Embodiments of a mobile device transmitter and methods for transmitting signals in different signal dimensions are generally disclosed herein. The mobile device transmitter comprises a mapper to map a block of two or more input modulation symbols to different signal dimensions comprising two or more spatial dimensions, and linear transform circuitry to perform a linear transform on the block of mapped input modulation symbols to generate a block of precoded complex-valued output symbols such that each output symbol carries some information of more than one input modulation symbol. The mobile device also comprises transmitter circuitry to generate time-domain signals from the blocks of precoded complex-valued output symbols for each of the spatial dimensions for transmission using the two or more antennas. The precoded complex-valued output symbols are mapped to different signal dimensions comprising at least different frequency dimensions prior to transmission.

    Abstract: Technology to provide physical uplink control channel (PUCCH) resource allocation in time division duplex (TDD) for a hybrid automatic retransmission request-acknowledge (HARQ-ACK) transmission in a subframe n is disclosed. In an example, a user equipment (UE) can include first circuitry configured to detect a downlink control channel within a prior specified subframe that is received in time before the subframe n. The UE can include second circuitry configured to: determine that the downlink control channel detected within the prior specified subframe is one of a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (EPDCCH); and determine one of a legacy PUCCH resource for the HARQ-ACK transmission when the downlink control channel detected within the prior specified subframe is the PDCCH or an enhanced PUCCH resource for the HARQ-ACK transmission when the downlink control channel detected within the prior specified subframe is the EPDCCH.
