  • Patent number: 10244562
    Abstract: Systems and methods for providing random access in a cellular communications network are disclosed. In general, the cellular communications network is an Orthogonal Frequency Division Modulation (OFDM) based cellular communications network (e.g., a 3 GPP LTE cellular communications network) or similar multi-subcarrier based cellular communications network. Random access is performed using a Physical Random Access Channel (PRACH) including subcarriers having a subcarrier frequency spacing that is equal to a subcarrier frequency spacing in one or more other channels of the uplink (e.g., a Physical Uplink Shared Channel (PUSCH)). As a result, the subcarriers in the PRACH are orthogonal to the subcarriers in the other channel(s) of the uplink, which in turn reduces, or substantially eliminates, interference between the PRACH subcarriers and the subcarriers of the other channel(s) of the uplink.

Across the various OFDM/A frame structures, the ratio of pilot sub-carriers to data sub-carriers across resource units (RUs) of decreases as the total number of sub-carriers across the RUs increases. In addition, some of the OFDM/A frame structures include different total number of sub-carriers yet same number of pilot sub-carriers.

  • Patent number: 9577755
    Abstract: A hybrid communications system implements different communication technologies to communicate data and information for particular communications directions in different portions of the system. Power line communications (PLC) signaling is used to deliver data and information from a gateway device to a light access point. Visible light communications (VLC) signaling is used to communicate data and information from the light access point to a user equipment (UE) device. Wireless radio signaling, wireless infrared (IR) signaling, or a combination of wireless IR signaling and PLC signaling is used to communicate data/information from the UE device to the gateway device. To efficiently control the VLC communications channel between the light access point and UE device, the UE device measures the VLC channel, e.g., calculating SNRs on a per VLC tone basis, and communicating VLC channel quality feedback information to the gateway device, which is forwarded to the light access point.
