    摘要： 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.

    摘要： Embodiments of a transmitter and methods for puncturing bits are generally described herein. Other embodiments may be described and claimed. In some embodiments, a multicarrier transmitter performs bit puncturing for pilot subcarriers in two operations. The first operation may uniformly removes bits from an encoded bit stream to achieve a predetermined code rate reserving space for pilot subcarriers of a predetermined number of antennas. The second operation may remove bits from each spatial data stream after interleaving in a manner to achieve approximately equal spacing between the punctured bits before interleaving. In this way, a conventional interleaver may be used. The second operation reserves space for pilot subcarriers when a greater number of antennas than the predetermined number are used.

    摘要： A multi-antenna transmitter is configured for orthogonal frequency division multiplexed (OFDM) communications. The multi-antenna transmitter includes circuitry to receive an input bit sequence for code block segmentation including adding filler bits based on a selected code block size, a encoder to encode the bit sequence and an interleaver configurable to perform interleaving operations on blocks of bits of various code block sizes of the bit sequence. A controller is to select the code block size for the interleaver and OFDM transmitter circuitry to transmit OFDM symbols on subcarriers utilizing more than one antenna. The OFDM symbols are generated at least in part from the interleaved blocks.

    摘要： An adaptive interleaver for wideband orthogonal frequency division multiplexed (OFDM) communications permutes a variable number of coded bits per OFDM symbol (Ncbps). The variable number of coded bits is calculated based on individual subcarrier modulation assignments for orthogonal subcarriers of a wideband channel. The interleaver matrix size may be based on the variable number of coded bits per OFDM symbol and the number of subchannels that comprise the wideband channel. The interleaver may add padding bits to the interleaver matrix to fill any remaining positions, and after performing an interleaving operation, the interleaver may prune the padding bits to provide a sequence of interleaved bits for subsequent modulation on the orthogonal subcarriers. A receiver may include an adaptive deinterleaver to reverse the process.
