    Abstract: Orthogonal DMRS ports with resource block reuse in a single cell is provided. ABS comprises: a BBE and RUs. The BS transmits user data to each of a plurality of UEs on a PDSCH using a PRB allocation for the cell. The PRB and cell are the same for all UEs. The PRB comprises DMRS symbols. The BS transmits user data to each UE on the PDSCH using a respective non-intersecting subset of the RUs. No RU transmits user data on the PDSCH using the PRB to more than one UE. The BBE: determines non-intersecting sets of DMRS ports; assigns one set to each UE; and causes the BS to transmit UE-specific DMRS to UE on the DMRS ports in the set assigned to that UE using only a respective non-intersecting subset of RUs used for transmitting user data to that UE on the PDSCH using the PRB.

    Abstract: Systems and methods for automatic X2-U/Xn-U link selection are provided herein. In one example, a method includes determining whether a local communication link between a first base station (FBS) and a second base station (SBS) is possible. In response to determining that the local communication link is possible, the method includes sending a request, including a local IP address for a FBS BBU, to the SBS for an address suitable for establishing a communication link. The method includes determining whether to include a local IP address for an SBS BBU in a response to the request. In response to determining to include the local IP address for the SBS, the method includes sending the response, including the local IP address for the SBS BBU to the FBS. The method includes establishing the local communication link between the FBS and SBS using the local IP addresses without using a security gateway.

    CPC classification number: H04J3/0667

    Abstract: One embodiment is directed to a technique for in-band signaling of time stamp information where a kernel driver executing in kernel space modifies a received timing message (for example, a Precision Time Protocol (PTP) Delay Request message) to include timing information associated with the time the timing message was received by a network interface. This is done so that an application running in the user space can obtain the timing information from the modified timing message and reconstruct a timestamp for the received timing message (for example, a PTP T4 timestamp) for use in implementing at least a part of a packet-based synchronization protocol (for example, the PTP).

    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.
