Abstract: A base station may make more efficient use of resources by transmitting data in a control region of a slot in addition to a data region. In order to avoid performance loss, the base station may adjust the data transmission in the control region in comparison to a data transmission in a data region and may signal an indication to a UE to assist the UE in receiving the data transmission in the control region. An apparatus for wireless communication at the UE receives the indication from the base station regarding the data transmission in the control region and uses the indication to perform rate matching or demodulation of the data transmission in the control region. The indication may indicate any of a different MCS/rank/TPR, a reduced MCS/rank/TPR, an MCS/rank/TPR delta, a control span for a group of UEs, and a starting symbol for the data transmission. The indication may also indicate that there is no data transmitted on resources in the control region.

Abstract: A pedestrian-located UE monitors selected subframes of a sidelink resource to detect periodic transmissions from other mobile devices to assist it in selecting a free resource for its own sidelink transmissions. The subframe selection is based on a cost metric which takes into account a probability of missing detection of a transmission with periodicity p from another mobile device, an average number of transmissions with periodicity p that are expected from another mobile device within a predefined transmission period of the mobile device, and a number of transmission cycles of the mobile device that need to occur in order to have a single potential collision with each periodic transmission from said at least on other wireless communication. The method provides a trade-off between avoiding future collisions and battery life.

Abstract: Packet loss mitigation may be provided. First, queue control data may be sent to a first container and then a route may be stalled after sending the queue control data. The route may correspond to a data path that leads to the first container. Next, modified queue control data may be received from the first container and the first container may be deleted safely with empty queues, preventing packet loss in response to receiving the modified queue control data.

Abstract: Methods and apparatus for using communications channels corresponding to frequency bands subject to cellular network, e.g., LTE, interference and/or other interference are described. The methods are well suited for use of cable networks where communications over a coax cable or via cable device may be subject to LTE interference. In various embodiments data traffic is classified based on whether the traffic corresponds to a protocol that supports a retry communications mechanism in the event of a communication error, the type of traffic data and/or the priority of the traffic data. In some embodiments data being communicated using a protocol which supports a retry mechanism are routed over channels subject to interference even if, in some cases, the packets correspond to data which has a higher priority or QoS requirements than packets, e.g., best effort packets, which are transmitted using a protocol that does not support a packet retry mechanism.

In addition, devices namely a wireless device, a radio access network node (e.g., Base Station Subsystem), and a core network node (e.g., Serving GPRS Support Node) that implement these techniques are described herein.

Abstract: Servicing a pseudowire communication across multiple Administrative Systems (AS) by components of packet data networks. A first Provider Edge (PE) router of a first AS receives a first Interior Gateway Protocol (IGP) message from a source PE router of the first AS that includes pseudowire data. The first PE router creates a first Border Gateway Protocol Link State (BGP-LS) message that includes the pseudowire data and transmits the first BGP-LS message to a second PE router of a second AS and intended for a destination PE router of the second AS. The first PE router then receives a second BGP-LS message from the second PE router that includes modified pseudowire data. The first PE router creates a second IGP message that includes the modified pseudowire data and transmits the second IGP message to the source PE router.

Abstract: The present disclosure relates to a clustering approach for sensor nodes of a wireless sensor network. This clustering approach, equal distance different members, balances the power burden amongst sensor nodes by deriving an optimal number of sensor nodes at each segment of a length. To this end, the present disclosure describes a linear wireless sensor network wherein the distance between adjacent cluster heads is equal while the number of and distance between sensor nodes in each cluster is different. A power consumption model is derived to aid in the determination of the optimal number of sensor nodes within each cluster. Following evaluation of the cluster approach in comparison with previously described approaches, the present disclosure is observed to improve network longevity and reduce power consumption by deliberately increasing the density of sensor nodes nearest a base station.

Abstract: The present invention discloses a data retransmission method, a device, and a system, and relates to the communications field, so as to resolve a prior-art problem that when a device transmits data by using an unlicensed carrier, the data cannot be retransmitted because a channel needs to be preempted again. A specific solution is as follows: A first device transmits data to a second device by using a first carrier, where the first carrier is an unlicensed carrier. The first device obtains status information of the first carrier, where the status information is used to determine whether the first carrier is available. When the first carrier is unavailable, the first device retransmits the data to the second device by using a second carrier, where the first carrier and the second carrier are different carriers. The present invention is used for data retransmission.

In various embodiments, a measurement gap pattern is determined and provided (via a serving frequency) to a user equipment (UE) in conjunction with frequency identification information identifying at least one target frequency. In accordance with the measurement gap pattern, the UE tunes a receiver to the target frequency and receives a reference signal upon which measurement operations are performed. Additional target frequencies can also be specified for the measurement gap pattern. In other embodiments, the frequency identification information identifies a band of target frequencies, any of which can be measured using the measurement gap pattern. In further embodiments, target frequencies employing overlapping reference signals are grouped into a timing group indicated by the frequency identification information.

Abstract: A pairing scheme may add devices to a mesh network automatically. Assuming that at least one device is already part of the mesh network, this scheme may allow devices that have not been paired yet to be automatically added to the mesh, eliminating manual pairing processes. When a new device is powered on, it may broadcast a connectable advertisement packet. The payload of this packet may be secure and not understood by the recipient device. Rather, only a server may have a copy of the device key, and can thus decrypt the advertising packet. The server sends a packet back with a network key and information, and the device then becomes part of the network.
