Abstract: Example embodiments presented herein are directed towards a Policy and Charging Rules Function (PCRF) node, a network node and a wireless device, as well as corresponding methods therein, for monitoring an ability of a wireless device to receive downlink data. The example embodiments presented herein provide a means of notifying an application server of when a wireless device is reachable. Thus, by knowing when the wireless device is reachable, the application server may avoid sending communication request to the wireless device when the device is unavailable. Thus, unnecessary signaling may be avoided.

Abstract: Computing nodes are coupled via a network to communicate as a tree structure that performs a distributed computation. The nodes include a root node, intermediate nodes, and leaf nodes. At least some of the nodes obtain redundant results that are communicated together with a final result to the root node. The root node compares the redundant results to the final result to verify the final result.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may determine separate uplink (UL) power limitations for multiple transmission time interval (TTI) durations based on distinct power control parameters. In some cases, an adjustment factor or a power backoff may be applied to communications using one TTI duration to ensure that total transmit power does not exceed a threshold. The UE and the serving base station may also identify one or more demodulation reference signal (DMRS) windows. UL data transmissions may be demodulated based on a DMRS sent during the same window. Transmit power control (TPC) commands may be applied at the beginning of each window. However, if an UL transmission is scheduled at the beginning of the window, the UE may wait until a DMRS transmission or until no more transmissions are scheduled for the window before applying the TPC adjustment.

Abstract: A relaying apparatus in a communication network has ports and a memory storing an address table where addresses of apparatuses connected to the respective ports are registered. The ports include a first and second particular ports to be connected in the communication network permitting a broadcast frame having been transmitted via the first particular port to be received via the second particular port. Upon receiving the broadcast frame via the second particular port, the relaying apparatus makes a determination whether or not a transmission-source address of the received broadcast frame is registered to a port other than the first and second particular ports in the address table. The relaying apparatus cancels the received broadcast frame when making the determination affirmatively.
