    摘要: A method of operating a wireless communication device or a radio access node comprises addressing multi-subcarrier system resources using at least one of multiple different numerologies available within a single carrier, wherein the multiple different numerologies comprise a first numerology having resource blocks with a first bandwidth and a first subcarrier spacing, Δf1, and a second numerology having RBs with a second bandwidth and a second subcarrier spacing, Δf2, which is different from Δf1, and wherein the first numerology is aligned in the frequency domain relative to a frequency reference, Fref, according to m*Δf1+Fref and the second numerology is aligned in the frequency domain relative to the frequency reference, Fref, according to n*Δf2+Fref, where m and n are integers. The method further comprises transmitting and/or receiving information within the single carrier according to the at least one of the multiple different numerologies.

    摘要: Certain aspects of the present disclosure relate to methods and apparatus for mitigating resource conflicts between ultra low latency (ULL) and legacy transmissions. A base station may determine a region of a subframe having overlapping resource allocations for a first device of a first type (e.g., ULL device) and a second device of a second type (e.g., legacy device), wherein the first device of the first type has a capability to perform certain procedures with low latency relative to the second device of the second type that lacks the capability. The base station may modulate data from the region of the subframe for transmission to the first and the second devices, using a hierarchical modulation scheme.

    摘要: A communication device is configured to perform symbol mapping of bits to generate modulation symbols using one or more modulations. The device may employ a blended modulation composed of bit labels or symbols having different numbers of bits per symbol and different modulations. For example, the device may symbol map bit labels/symbols having first number of bits per symbol to first modulation, and the device may symbol map labels/symbols having second number of bits per symbol to second modulation. The device may be configured to perform forward error correction (FEC) or error correction code (ECC) and coding of information bits to generate coded bits that subsequently undergo symbol mapping. The device may be configured to operate based on different operational modes based on substantially uniform steps of rates, or bits per symbol, and energy per bit or symbol to noise spectral density ratio (Eb/N0 or Es/N0).

    摘要: A demapping scheme, having a low computational cost, suitable for any transmission in which only exhaustive demapping can guarantee good performance. The scheme, proposed in this document, can be used in any transmission based on no differential modulation. For example the proposed scheme can be directly applied to a transmission on flat fading AWGN channels or to a transmission on frequency selective channels after equalization or on each sub-carrier of an OFDM System. The proposed solution can be applied for the demapping of any communication system. The proposed scheme can be used for rotated and un-rotated constellation.
