摘要： A network infrastructure for a wireless communication system is disclosed. The infrastructure comprises a fronthaul network, an RRH pool, a radio service chain (RSC). The RSC is coupled to the fronthaul network and the RRH pool for allocating the RRH resources. The RSC comprises an orchestrator and a remote radio head (RRH) controller. The orchestrator is used for receiving a radio resource request from the at least one C-RAN and converting the radio resource request into a RRH specific command. The RRH controller is used for slicing the RRH resources to create virtual RRHs according to the radio resource request.

摘要： Embodiments relate to providing simultaneous digital and analog services in optical fiber-based distributed radio frequency (RF) antenna systems (DASs), and related components and methods. A multiplex switch unit associated with a head-end unit of a DAS can be configured to receive a plurality of analog and digital downlink signals from one or more sources, such as a service matrix unit, and to assign each downlink signal to be transmitted to one or more remote units of the DAS. In one example, when two or more downlink signals are assigned to be transmitted to the same remote unit, a wave division multiplexer/demultiplexer associated with the multiplex switch unit can be configured to wave division multiplex the component downlink signals into a combined downlink signal for remote side transmission and to demultiplex received combined uplink signals into their component uplink signals for head-end side transmission.

摘要： Described are techniques for limiting bandwidth requirements for user equipment UE data sent on a front haul link between a remote radio head RRH and a baseband unit BBU. For a given UE a subset of a plurality of beams is selected based on received energies of the plurality of beams, and for the given UE only data from the selected subset of beams transmitting on a front haul link. Multiple techniques are detailed for how the subset is selected, including (when UE allocation information is available) averaged received beam energy, total received beam energy, maximum received beam energy and also (when UE allocation information is not available). For further bandwidth reduction a special data compression technique uses the received energies of each beam to select a minimum gain offset value after dividing the data into I and Q components.

摘要： Automated control of simulcast ratios based on network traffic data provides efficient network capacity management. In one aspect, a remote switching matrix can be utilized at a venue to couple remote transceiver units (RTUs) with different antenna ports, for example, of one or more multi-beam antennas deployed at the venue. A simulcast ratio that can be utilized to support traffic demand at the venue can be determined and implemented by creating dynamic connections between the RTUs and the antenna ports. In one aspect, the simulcast ratio can be modified based on changes in network traffic at the venue that are monitored via self-organizing network devices. In addition, one or more antenna beams of the multi-beam antennas are remotely steered or rotated based on a location of the traffic.

摘要： 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.

摘要： Techniques are disclosed relating to signaling and frame structure for massive MIMO communication systems. In some embodiments, an apparatus is configured to receive an uplink pilot symbol from a mobile device over a first channel and receive uplink data from the mobile device over the first channel, where the uplink data is included in one or more orthogonal frequency division multiplexing (OFDM) symbols at a symbol rate. In these embodiments, the apparatus is configured to, determine channel information based on the pilot symbol, precode downlink data based on the channel information, and transmit the precoded downlink data to the mobile device. In these embodiments, a transition interval between receiving the uplink pilot symbol and beginning to transmit the precoded downlink data corresponds to less than five OFDM symbols at the symbol rate. This may facilitate reciprocity-based precoding for fast-moving mobile devices, in some embodiments.
