Abstract: A method for adaptive coding and modulation. The method includes generating a set of mapping functions and transmitting a tth set of transmit symbols where 1?t?T and T is a maximum number of symbol transmissions. Transmitting the tth set of transmit symbols includes transmitting each transmit symbol in the tth set of transmit symbols. Each transmit symbol is transmitted by a respective transmitter. Transmitting each transmit symbol includes generating a tth set of mapped symbols, generating each transmit symbol from the tth set of mapped symbols, and transmitting each transmit symbol. Generating the tth set of mapped symbols includes applying a mapping functions subset of the set of mapping functions on a respective data vector. Each mapping function in the mapping functions subset depends on a respective mapped symbol in an rth set of mapped symbols where 0?r?T.

Abstract: A method and apparatus is for generating a modulation signal that comprises a resource block. A resource element sequence, Mnp, of M pilot symbols is determined that corresponds to an nth of N subcarriers. A pilot frequency domain sample sequence, rnp, corresponding to the resource element sequence Mnp comprises a quantity, RnNZ, of non-zero magnitude pilot frequency domain samples. RnNZ is determined based on M and an excess bandwidth, ?, of an adjacent subcarrier filter. The resource element sequence Mnp, which has no inter-subcarrier interference, is multiplexed with N?1 resource element sequences to form the resource block. The modulation signal is generated by modulating each subcarrier of the N subcarriers with a corresponding resource element sequence of the N resource element sequences and filtering each of the modulated subcarriers using a subcarrier filter. The resource element sequence Mnp is used during receiving for efficiently determining a channel estimate.

Abstract: Systems, methods, and apparatuses for using band-limited subframes in wireless communication networks are provided. During the band-limited subframes, the macro cell base station may mute its transmission or transmit at a low power over some frequency sub-band, while transmitting at a normal or higher power over other frequency sub-band. Correspondingly, the small cell base station may communicate with UEs within its coverage at the frequency sub-band that the macro cell base station transmits at a low power. The band-limited subframe enables the small cell base station to communicate with the UE with reduced interference, and in the meantime, increases the throughput of macro cell base station as it does not require the macro cell base station to completely mute its transmission during the band-limited subframe.
