  • Patent number: 10231232
    Abstract: Embodiments describe example radio access networks where uplink and downlink communications operate asymmetrically. In one embodiment, an inverse fast Fourier transform and an add cyclic prefix operation is performed on a downlink communications by a baseband unit. In an uplink communication using the same baseband unit, a corresponding fast Fourier transform and a remove cyclic prefix operation are performed at a remote radio unit. This generates different levels of traffic on a physical communication link between the baseband unit and the remote radio unit for uplink and downlink communications with similar characteristics.

  • Patent number: 10064242
    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.

  • Patent number: 9924432
    Abstract: Device-to-device (D2D) communications between user equipment (UE) allows two UEs in a long-term evolution (LTE) network to communicate directly with each other without the need to first send their communications to a network (such as via an evolved node B). In order to communicate in a D2D mode, the UEs first need to discover each other. One method of allowing the UEs to discover each other involves the use of a physical uplink control channel (PUCCH). After a network determines that certain UEs would benefit from D2D communication, the UEs can be set up to send and receive discovery signals using the PUCCH.
