Abstract: Systems and methods disclosed herein describe a centralized-processing cloud-based RAN (C-RAN or cloud-RAN) architecture that offers reduced front-haul data-rate requirements compared to common-public-radio-interface (CPRI) based C-RAN architectures. Base-band physical-layer processing can be divided between a BBU Pool and an enhanced RRH (eRRH). A frequency-domain compression approach that exploits LTE signal redundancy and user scheduling information can be used at the eRRH to significantly reduce front-haul data-rate requirements. Uniform scalar quantization and variable-rate Huffman coding in the frequency-domain can be applied in a compression approach based on the user scheduling information wherein a lossy compression is followed by a lossless compression.

Abstract: Technology for performing device-to-device (D2D) discovery is disclosed. A user equipment (UE) can identify a D2D discovery resource that is M subframes in a time domain, wherein M is a positive integer greater than one. The UE can generate K demodulation reference signal (DMRS) sequences to be transmitted from the UE for each subframe in the D2D discovery resource, wherein K is a positive integer greater than two. The UE can apply a predetermined orthogonal cover code (OCC) to each DMRS sequence. The predetermined OCC can be selected based on a value of M and a value of K. The UE can transmit the K DMRS sequences for each of the M subframes of the D2D discovery resource.

Abstract: Technology for a base station operable to encode guard interval (GI) discrete Fourier transform (DFT) spread orthogonal frequency-division multiplexing (OFDM) (GI-DFT-s-OFDM) data symbols for transmission to a user equipment (UE) is disclosed. The base station can identify GI-DFT-s-O 5 FDM data symbols for transmission to the UE. The base station can encode the GI-DFT-s-OFDM data symbols for transmission to the UE in a subframe. The subframe can be in accordance with a flexible subframe structure that begins with a demodulation reference signal (DMRS) sequence followed by a GI sequence in a first symbol of the subframe. The subframe can further comprise one or 10 more subsequent symbols in the subframe that each include a GI-DFT-s-OFDM data symbol followed by a GI sequence.
