  • Publication number: 20210282101
    Abstract: One embodiment is directed to a device for fronthaul communication between a baseband unit (BBU) and a remote unit (RU). A processor of the device is configured to receive, using a first fronthaul interface of the device, fronthaul data originating from said first one of the BBU and the RU. The fronthaul data is formatted according to a first fronthaul protocol when received using the first fronthaul interface. The processor is further configured to format at least some of the fronthaul data received using the first fronthaul interface so as to be formatted according to a second fronthaul protocol thereby producing reformatted fronthaul data and forward, using a second fronthaul interface of the device, the reformatted fronthaul data towards said second one of the BBU and the RU.

  • Publication number: 20200366542
    Abstract: A distributed radio frequency communication system includes a remote radio unit (RRU and a baseband unit (BBU) and facilitates communication between a wireless terminal and a core network. The RRU receives a radio frequency signal from a wireless terminal and convert the radio frequency signal to digital baseband samples using receiver circuitry and an analog-to-digital converter. The RRU then adaptively compresses the digital baseband samples, using adaptive compression circuitry, to create fronthaul uplink information, and sends the fronthaul uplink information over a fronthaul link to the BBU using an adaptive fronthaul protocol. The RRU also receives fronthaul downlink information over a fronthaul link from the BBU using an adaptive fronthaul protocol and generates frequency-domain samples, based on the fronthaul downlink information received.

  • Patent number: 10749721
    Abstract: A distributed radio frequency communication system facilitates communication between a wireless terminal and a core network. The system includes a remote radio unit (RRU) coupled to at least one antenna to communicate with the wireless terminal. The RRU includes electronic circuitry to perform at least a first portion of a first-level protocol of a radio access network (RAN) for communicating between the wireless terminal and the core network. The system also includes a baseband unit (BBU) coupled to the core network, and configured to perform at least a second-level protocol of the RAN. A fronthaul link is coupled to the BBU and the RRU. The fronthaul link utilizes an adaptive fronthaul protocol for communication between the BBU and the RRU. The adaptive fronthaul protocol has provisions for adapting to conditions of the fronthaul link and radio network by changing the way data is communicated over the fronthaul link.

  • Patent number: 10368374
    Abstract: Improvements to signaling procedures for use in physical random access channel (PRACH)-based proximity detection are disclosed. Signaling and signaling processes from a serving base station may trigger a more efficient and reliable transmission of PRACH from related user equipment (UE). At the dynamic power nodes (DPNs) monitoring for such PRACH-based proximity, features are disclosed which establish neighbor lists for more efficient management of detection and proximity activation.

  • Publication number: 20190208575
    Abstract: Methods and systems for facilitating communication between a core network and a wireless terminal in an upper first-level protocol unit (UL1) of a radio access network (RAN) as disclosed. An upper first level protocol unit (UL1) performs a first portion of a first-level protocol of the RAN in a first apparatus and communicates over a fronthaul link with a lower first-level protocol unit (LL1). The LL1 is in a second apparatus separate from the first apparatus. A communication quality parameter for communication between the first apparatus and the LL1 is determined, and a message related to the communication quality parameter is sent by the UL1 to an entity of the RAN other than the LL1.

  • Patent number: 10320550
    Abstract: Techniques for estimating and reporting channel quality indicator (CQI) are disclosed. Neighboring base stations may cause strong interference to one another and may be allocated different resources, e.g., different subframes. A UE may observe different levels of interference on different resources. In an aspect, the UE may determine a CQI for resources allocated to a base station and having reduced or no interference from at least one interfering base station. In another aspect, the UE may determine multiple CQI for resources of different types and associated with different interference levels. For example, the UE may determine a first CQI based on at least one first subframe allocated to the base station and having reduced or no interference from the interfering base station(s). The UE may determine a second CQI based on at least one second subframe allocated to the interfering base station(s).

  • Patent number: 9949248
    Abstract: Methods and apparatus are disclosed for improving blind-decoding and interference suppression associated with interference from non-serving cells in a wireless network, specifically, performing interference suppression on the non-serving cell control channel. Various aspect employ network-assisted blind-decoding of non-serving cell signals at UEs through the coordination, communication, and use of communication restriction conditions. Network aspects may restrict certain communications between eNBs and served UEs, and communicate the restrictions to non-served UE. The non-served UEs can then leverage the restrictions for more efficient blind-decoding of interfering eNB signals and interference cancellation of interfering eNB signals.
