Abstract: A C-RAN includes a plurality of remote units; and a central unit communicatively coupled to the remote units via a fronthaul network. The central unit is configured to determine sets of data to be sent to respective subsets of remote units across the fronthaul network. The central unit is also configured to determine a mapping of each of the sets of data to a respective one of the subsets of remote units. The central unit is also configured to, for each of the sets of data, if at least one of the multicast groups wholly contains the respective subset of remote units mapped to that set of data, transmit that set of data to the respective subset of remote units over the fronthaul network by multicasting that set of data to the multicast group that best matches the respective subset of remote units mapped to that set of data.

Abstract: One embodiment is directed to adaptive predictive uplink receive chain processing that involves determining predicted data for one or more early data symbols of a slot based on first baseband IQ data received for the slot. The predicted data for the early data symbols of the slot comprises a predicted version of data used at some point in performing a first portion of uplink receive processing for the early data symbols. The first portion of the uplink receive processing for the early data symbols of the slot is performed using the predicted data. Actual data corresponding to the predicted data is determined based on at least second baseband IQ data received for the slot. In connection with performing a remaining portion of the uplink receive processing for the early data symbols, the preliminary output data for the early data symbols of the slot are adapted based on the actual data.

Abstract: A C-RAN includes a plurality of remote units; a central unit communicatively coupled to the remote units via a fronthaul network; and an entity coupled to the fronthaul network configured to perform deep packet inspection. The central unit is configured to determine sets of data to be sent to respective subsets of remote units across the fronthaul network and determine a mapping of each of the sets of data to a respective one of the subsets of remote units. The central unit is also configured to add a respective indicator, based on the mapping, to packets for each set of data, wherein each respective indicator indicates each remote unit that the respective packet and set of data is intended for. The central unit is also configured to transmit the packets for the sets of data, each with the respective indicator, to the entity over the fronthaul network.

Abstract: Among other things, a communication system comprising at least one remote unit and at least one controller is described. The at least one remote unit exchanges radio frequency (RF) signals with mobile devices. Each RF signal comprises information destined for, or originating from, one of the mobile devices. The controller is communicatively coupled to the at least one remote unit and comprises a real-time scheduler for assigning airlink resources to the mobile devices for the information. The at least one controller and the at least one remote unit are configured so that the physical layer functions for an air interface are split between the controller and the at least one remote unit. The at least one controller and the at least one remote unit are configured so that the split of the physical layer functions for at least some of a first channel of the air interface differs from the split of the physical layer functions for a second channel of the air interface.

Abstract: A communication system includes remote units, a UTC or GPS reference timing source, and a controller. The controller includes one or more modems and is connected to an external network, at least one of the modems being a baseband modem and being configured to pass first data corresponding to the information. The controller is separated from the remote units by an intermediate network over which second data corresponding to the information is transmitted in frames between the controller and the remote units. The second data includes baseband data. A controller clock is synchronized with the reference timing source and provides timing information to the controller. A remote unit clock is synchronized with the controller clock and provides timing information to a remote unit, the controller and the remote unit being configured to transmit time stamp messages to synchronize the controller clock and the remote unit clock.
