Abstract: In a radio network having a plurality of first users on channel (FUOCs) and one or more second users on channel (SUOCs), a method and apparatus for a SUOC to select a channel to co-occupy based in part upon the expected impact on the FUOC. The FUOC collects signal parameters associated with the FUOC, such as actual rate, bandwidth, received signal power, and noise power, and uses the signal parameters to calculate the expected impact. In some embodiments, the expected impact is proportional to the ratio of the FUOC's actual rate and the FUOC's possible code rate.

Abstract: Disclosed is a method and system for use of orthogonal coding to manage control channel load. Based on evaluation of downlink air interface load, a base station dynamically toggles use of orthogonal coding of downlink control information (DCI) messages for transmission on a downlink control channel. When downlink load is high, the base station may responsively operate in a state in which the base station orthogonally codes DCI messages to facilitate transmitting multiple DCI messages per set of resource elements on the downlink control channel, possibly boosting transmission power in those resource elements to help facilitate successful transmission. Whereas, when downlink load is not high, the base station may responsively operate in a state in which the base station does not orthogonally code DCI messages and thus sends just one DCI message per set of resource elements.

Abstract: A compute node with multiple transfer processes that share an Infiniband connection to send and receive messages across a network. Transfer processes are first associated with an Infiniband queue pair (QP) connection. Then send message commands associated with a transfer process are issued. This causes an Infiniband message to be generated and sent, via the QP connection, to a remote compute node corresponding to the QP. Send message commands associated with another process are also issued. This causes another Infiniband message to be generated and sent, via the same QP connection, to the same remote compute node. As mentioned, multiple processes may receive network messages received via a shared QP connection. A transfer process on a receiving compute node receives a network message through a QP connection using a receive queue. A second transfer process receives another message through the same QP connection using another receive queue.

Abstract: In one example, techniques of this disclosure may enable a point of local repair (PLR) network device to signal availability of link protection or node protection to a merge point (MP) network device and enable a network device to actively determine whether or not it is a merge point router. Based on whether or not the network device determines it is a MP, the network device may selectively clean up LSP states when there is an upstream link or node failure. The RSVP-TE protocol may be extended to enable a network device to send a tear down message to a downstream router, which may enable the downstream router to conditionally delete locale LSP state information. In some instances, a PLR network device may directly send a tear down message to a MP network device even though the PLR network device may not have a working bypass LSP.

Abstract: A simultaneous transmit and receive (STR) technology is described. The eNB is configured with a downlink centric measurement threshold and an uplink centric measurement threshold which increase overall capacity in the wireless cellular network. A signal measurement command is transmitted from the eNB to the UE instructing the UE to take a signal quality measurement. The signal quality measurement is received from the UE at the eNB. It is determined whether the signal quality measurement is greater than the downlink centric measurement threshold and whether the signal quality measurement is greater than the uplink centric measurement threshold. The downlink centric measurement threshold, the uplink centric measurement threshold, and the DL/UL ratio are configured to increase capacity in the wireless cellular network through selective use of STR.

Abstract: A system for providing communications over a communications network includes a communications interface and a processor. The communications interface communicates over the communications network. The processor directs a communications scheduler to determine at least one metric for a path within the communications network. The processor also selects a data flow for the path and determines whether to transmit a packet in the selected data flow based on the at least one metric. The processor then directs a communications protocol handler to generate the packet for the selected data flow.

Abstract: Methods and apparatuses for a User Equipment (UE) to receive signaling of UE-common Downlink Control Information (DCI) in a set of Physical Resource Blocks (PRBs) over a Transmission Time Interval (TTI) are provided. The UE demodulates UE-common DCI using a Reference Signal (RS) that is scrambled by a UE-common scrambling sequence. The UE may assume that RS having a same precoding is transmitted in the set of PRBs over different TTIs. The UE may determine the scrambling sequence implicitly from an identity of a point transmitting the UE-common DCI or explicitly by higher layer signaling. The UE may determine the PRBs of UE-common DCI transmission by broadcast signaling or by higher layer signaling.

Abstract: A method for communication includes storing packets received from a sending node over a communication link in a receive buffer of a receiving node. The receive buffer includes one or more blocks having a first block size. A first credit count, corresponding to a number of available blocks in the receive buffer, is derived. The first credit count is converted to a second credit count so as to represent an available space in the receive buffer in accordance with a second block size, which is different from the first block size. A transmission rate of the sending node is controlled by publishing the second credit count to the sending node over the communication link.
