A system and method for optimizing the end-to-end latency transfer rates over an air interface employing a Multi-hop Relays (MHR). The present system and method provides fast signaling process when no Downlink/Uplink Bandwidth allocation changes are employed, thereby bypassing PHY/MAC/IP Stack processing. The solution is intended for the new generation of 5G millimeter band multi-hop relays.

System and method for fast relay for bandwidth allocation signaling

Systems and methods implement Data-Over-Cable Service Interface Specification (DOCSIS) time protocol (DTP) calibration. A testing laboratory measures a DTP timing error for a test configuration representative of a DOCSIS network to determine DTP calibration data. The DTP calibration data is stored in association with a DTP calibration testing setup of the DOCSIS network in a DTP calibration platform. An operational cable modem termination system (CMTS) conforming to the DTP calibration testing setup retrieves and applies the DTP calibration data from the DTP calibration platform based on the DTP calibration testing setup.

DTP calibration platform

Systems and methods disclosed herein provide an inter-node interface for communication between client nodes, such as modems, in a local communication network (LCN), where local data does not pass through a network hub or mobile core. To improve signal strength, SINR and handoff speeds in the LCN, the disclosed systems and methods also enable a client node within the LCN to self-direct simultaneous transmission of a common data packet by a plurality of client nodes, without employing components of the Xhaul transport system for coordination.

Enabling inter-node communication using local communication networks

Systems and methods presented herein provide for reducing latency in wireless service through a communication link comprising a Modem Termination System (MTS) and a modem. The communication link is coupled with a virtualized wireless link. In one embodiment, a method includes transferring a buffer status report (BSR) from a user equipment (UE) through the communication link to a control portion of the virtualized wireless link, generating a wireless grant to allow the data of the UE through virtualized wireless link, and generating a backhaul grant for the UE to transfer data through the communication link based on the wireless grant information.

A converged small cell communication system includes a mobile network core, a data over cable service interface specification (DOCSIS) core, and a common policy platform for managing a service flow of a user equipment within a communication vicinity of the small cell communication system. The mobile network core includes a policy engine and a packet data network gateway (PGW). The DOCSIS core includes a packetcable multimedia (PCMM) unit having a policy server and an application manager, and a cable modem termination system (CMTS).

Systems and methods presented herein provide for multichannel communications. In one embodiment, a communication system includes a plurality of traffic channels operable to link to a UE via one or more communication networks. The communication system also includes a traffic processor operable to receive a request for data from the UE, to evaluate the traffic channels based on the requested data, to select a first and a second of the traffic channels based on the evaluation, and to convey the data over the first and second traffic channels to the UE.

Beamforming for adapting wireless signaling beams in an adaptive and agile manner is contemplated. The beamforming may be characterized by adaptively constructing beam form parameters to provide wireless signaling in a manner that maximizes efficiency and bandwidth according to device positioning relative to a responding base station.

Efficient adaptable wireless network system with agile beamforming

One embodiment is a method and includes receiving at a termination element of a first network a bandwidth report ('BWR'), in which the BWR includes information regarding a data transmission opportunity over a second network for at least one endpoint data; scheduling a first network transmission opportunity for the at least one endpoint data using information derived from the received BWR; and receiving from a first network forwarding device the at least one endpoint data in accordance with the scheduled first network transmission opportunity.

Techniques for wireless access and wireline network integration

A system and method for reducing latency in a wireless-to-wired backhaul environment, such as a LTE-Backhaul environment. In the LTE-Backhaul embodiment, the system and method rely on a modification to the eNodeB (eNB). This modification causes the eNB to generate a bandwidth report (BWR) upon receipt of a buffer status report (BSR) associated with an RRC encapsulated NSA signaling. The BWR provides a notification to the backhaul system that SCTP signaling, which is associated with the RRC encapsulated NSA signaling, is forthcoming. In addition, the present system and method provides for a periodic transmission of a grant (e.g., a MAP in a DOCSIS embodiment) in the backhaul portion. The backhaul grant provides for the modem to immediately forward the BWR to the modem termination system (MTS) upon receipt of the BWR such that the MTS may prepare a grant for the forth coming SCTP signaling.

System and method for pipelining LTE signaling

A method for transmitting data through a multi-media communication network includes converting transmission entities into data symbols at a first communication device, transmitting the data symbols from the first communication device to a second communication device through at least two different types of communication media using only lower PHY layers of the at least two different types of communication media, and converting the data symbols into transmission entities at the second communication device. A network implementing a universal data link includes a first communication device configured to convert transmission entities into data symbols, a second communication device configured to convert the data symbols into transmission entities, at least a first communication medium and a second communication medium communicatively coupled between the first communication device and the second communication device, and a first physical-layer translator configured to translate data symbols without converting the data symbols into transmission entities.

One wireless telecommunications system includes a Mobile Central Office (MCO) for capacity sharing via a master scheduling system. The MCO is communicatively coupled to a plurality of wireless base stations, each being operable to handle a session from a wireless device and to handoff the session to another wireless base station when the wireless device moves into a range of the other base station. Each of the wireless base stations is operable to convey capacity information to the master scheduling system through the MCO, and to acquire capacity from one or more wireless base stations of another MCO when directed by the master scheduling system.
