Abstract: In described embodiments, a relatively optimum, ultra-low latency communication path with communication links operating in accordance herein provide for graded service in a near optimal, ultra-low latency communication system between points A and B. Points A and B are separated geographically over a relatively long distance where the curvature of the earth affects a direct path. Unlike typical systems, to provide the graded service in ultra-low latency networks, the service provider adds delay, or other service degradation, to one or more user connections, which is provided at greater implementation expense (e.g., higher cost to the service provider) in order to provide a lower fee service (e.g., lower cost to the service user) for certain users of the ultra-low latency network.

Abstract: A message (300) that has been transmitted in a mesh network from a source node (102) and intended for reception by a destination node (104) is received by a relay node (125) and also received by a number of other nodes (121, 123). A minimized latency can be obtained by the use of a timer such that the message is relayed by the relay node (125) only if no other node has already relayed the message.

Abstract: An Orthogonal Frequency Division Multiplexing (OFDM) communication network controls Device-to-Device (D2D) scheduling. The OFDM access point wirelessly exchanges wireless communications with a plurality of individual User Equipment (UEs) using scheduled UE resources in a shared resource range. The OFDM access point wirelessly receives a first D2D communication request for a first D2D UE and responsively schedules D2D resources for the first D2D communication request in the shared resource range. The OFDM access point detects D2D interference for one of the plurality of individual UEs and determines that the D2D interference exceeds a D2D interference threshold. The OFDM access point wirelessly receives a second D2D communication request for a second D2D UE and responsively schedules D2D resources for the second D2D communication request in a D2D dedicated resource sub-range.

Abstract: A Forwarding Information Base (FIB) caching system and scheme that selects and generates a minimal number of non-overlapping prefixes for the FIB cache to improve computer-based network communications and operations efficiency, accuracy and speed. Because the cached prefixes do not cover any longer prefixes in the full FIB, the present invention thus avoids cache-hiding issues. The system further comprises a FIB caching updating component that systematically handles cache misses, cache replacement, and routing updates.

Abstract: There lies a challenge to develop a technique of effectively establishing a direct communication link between client devices in a communication network. In some implementations, an associated STA is a client device which is associated with a particular access point (AP). A non-associated STA is a client device which is not associated with the AP. A tunneled probe request may be transmitted by an associated STA through the AP to be broadcast to other associated STAs. In some implementations, an active scan may be combined with a tunneled probe request in order to establish a communication link between an associated STA and a non-associated STA.

Abstract: Methods, systems, and devices for wireless communication are described. Wireless devices may operate in an extended connected discontinuous reception (eDRX) mode to increase energy efficiency and extend battery life. Control signaling may be used to initiate or support the extended sleep cycles associated with eDRX operation. In some cases, a system frame number (SFN) extension may be implemented to record frame cycles and differentiate SFNs that occur in a first frame cycle from SFNs that occur in a second frame cycle. Control techniques to support eDRX operation and maintain network synchronicity and compatibility may also be employed. In some examples, a wireless system may broadcast extended or dedicated system information updates to an eDRX capable device or devices. In some cases, devices may adjust the rate at which radio link monitoring (RLM) measurements are taken to timely determine radio link failures (RLFs) in conjunction with eDRX operation.

Abstract: A method in a wireless device is disclosed. The method comprises sending a scheduling request to a network node, and receiving, from the network node in response to the scheduling request, a grant of uplink resources. The method further comprises determining whether the granted uplink resources are at least equal to or larger than the resources required for transmission of both a buffer status report (BSR) and a sidelink BSR, and upon determining that the granted uplink resources are at least equal to or larger than the resources required for transmission of both the BSR and the sidelink BSR, communicating the BSR and the sidelink BSR to the network node in a single medium access control (MAC) protocol data unit (PDU).

Abstract: A conversation is handed over between an unlicensed data network and a cellular network. Voice conversations and/or video conversations may be seamlessly transitioned between cellular networks and unlicensed data networks (e.g., Wi-Fi), with a small transition time (e.g., less than a couple of seconds). The handover may occur from the unlicensed data network to the cellular network or from the cellular network to the unlicensed data network. During the transition between networks, cached registration data is accessed to speed up the authentication of the computing device switching networks. In some configurations, a user may specify preferences for switching between the unlicensed data and cellular networks. For instance, a user may specify a preference to use Wi-Fi networks before cellular networks or to use cellular networks before using Wi-Fi networks.

A radio frequency chain may be coupled to the output of the radio transceiver and configured to sample adjacent channel interference caused by the radio transceiver.

Abstract: A communication system, a base station, a user equipment (UE), and a timing synchronization method for the base station thereof are provided. The communication system includes a first base station, a second base station and the user equipment. The UE is located within coverage of the first base station and the second base station. The first base station and the second base station respectively measure signal stability of the user equipment so that the second base station selects the user equipment based on the measurements for the stability of the signals. The first base station computes a first timing error for transmitting or receiving message between the first base station and the user equipment then transmits the first timing error to the second base station. The second base station adjusts a timing difference between the first base station and the second base station through the first timing error.

Abstract: A method and system for supporting operation of a scheduler by providing indications of communication device transmit buffer status is provided. The indication of buffer status can be generated by a third-party device which is external to both the communication device and the scheduler. In some embodiments matched local and remote models of the buffer are maintained at the communication device and third-party device (or scheduler), respectively. The communication device monitors locally for drift of the model from the actual buffer status. When a level of mismatch in the model is detected, both the local and remote models are updated to mitigate the mismatch.
