Abstract: Systems and methods for dual-connectivity split-bearer packet management are presented. In one embodiment, a dual-connectivity, split-bearer base station, comprises: at least one centralized unit (CU) comprising a CU-CP) and at least one CU-UP; at least one DU coupled to the at least one CU-UP, wherein the at least one DU is coupled to one or more RUs configured as a first cell group to establish a first radio link for communicating with UE within a wireless coverage area; an eNodeB coupled to the at least one CU-UP, wherein the eNodeB comprises one or more RPs configured as a second cell group to establish a second radio link for communicating with UE within the wireless coverage area; and a traffic split controller configured to selectively direct PDCP packets to either the DU or the eNodeB as a function of packet delay times associated with the DU and the eNodeB.

Abstract: A base station for performing physical cell identifier (PCI) collision detection. The base station includes at least one processor configured to determine whether a PCI in a radio resource control (RRC) re-establishment message is the same as a PCI used by a cell implemented by the base station. The at least one processor is also configured to determine whether a cell radio network temporary identifier (C-RNTI) in the RRC Re-establishment message is outside a reserved range of C-RNTIs for the cell. The at least one processor is also configured to identify a possible PCI collision for the cell when (1) the PCI in the RRC Re-establishment message is the same as a PCI used by the cell; and (2) the C-RNTI in the RRC Re-establishment message is outside the reserved range of C-RNTIs for the cell.

Abstract: A base station includes a plurality of remote units (RUs), each being configured to exchange RF signals with at least one UE. The C-RAN also includes a controller communicatively coupled to the plurality of RUs via a fronthaul interface. The controller is configured to receive a public warning system (PWS) alert message. The controller is also configured to determine a number of bytes, based on a channel bandwidth of a wireless channel used by the base station, for each of a plurality of system information block messages. The plurality of system information block messages are broadcast wirelessly to the at least one UE.

Abstract: A small cell for selecting a physical cell identifier (PCI) includes at least one processor configured to determine a provisioned list of PCI values from a management system. The at least one processor is also configured to sort the PCI values in the provisioned list into a sorted list based on at least one predetermined pattern and modulo X values of the PCI values, where X is a predetermined integer. The at least one processor is also configured to determine an index for each sector implemented by the small cell based on a sector ID for the sector. The at least one processor is also configured to select, for each sector implemented by the small cell, a PCI value from the sorted list based on a sector ID of the sector.

Abstract: A small cell for automatic configuration of an operational parameter includes at least one processor configured to determine a provisioned list of operational parameters. The at least one processor is also configured to sort the provisioned list into a sorted list. The at least one processor is also configured to select the operational parameter from the sorted list based on a BC ID for the small cell, a sector ID for a sector implemented by the small cell, or some combination.
