Abstract: A first channel for carrying Layer 2 messages carries data that will not be retransmitted and for which decoding-related information need not be retained by the receiving node in the event of an unsuccessful decoding of the data, while a second channel carries data that will be retransmitted in the event that a negative acknowledgement is received by the transmitting node. In an example method, first and second subsets of Layer 2 messages are received on first and second physical data channels, respectively. Decoding-related information for unsuccessfully decoded messages in the first subset is retained for use with subsequent retransmissions, while decoding-related information for unsuccessfully decoded messages in the second subset is discarded without waiting for retransmissions. Acknowledgements or negative acknowledgements are sent for messages in the first subset, but may or may not be sent for messages in the second subset, in various embodiments.

Abstract: Systems and methods of using a packet order work (POW) scheduler to assign packets to a set of scheduler queues for supplying packets to parallel processing units. A processing unit and the associated scheduler queue is dedicated to a specific flow until a queue-reallocation event, which may correspond to the associated scheduler queue being idle for at least a certain interval as indicated by its age counter, or the queue being the LRU, when a new flow arrives. In this case, the scheduler queue and the associated processing unit may be reallocated to the new flow and disassociated with the previous flow. As a result, dynamic packet workload balancing can be advantageously achieved across the multiple processing paths.

The apparatus may be configured to select one of the first and second signal processing circuitry based on the complexity of input problems, the amount of transmission resources assigned to the apparatus, etc. In some embodiments, intermediate results of from the second signal processing circuitry are used as inputs to an operation performed by the first signal processing circuitry.

Abstract: A user equipment (UE) provides feedback about channel conditions. From a set of primary sub-bands subject to channel state information reporting by the UE, there is identified one or more of the primary sub-bands for reporting channel quality with a finer frequency-domain granularity than other primary sub-bands of the set (202). The one or more is less than all primary sub-bands in the set. In various embodiments, either the UE or the network can select which are the primary sub-bands to be identified for the finer granularity reporting, and the selection can be for example the best primary sub-bands or those with the highest variance in a measure of channel quality or random (206). Then for each of the identified primary sub-bands, the UE measures and reports the channel quality with the finer frequency-domain granularity for each secondary sub-band whose frequency lay within the respective identified primary sub-band.

Abstract: A method for communication includes, in a first network switch that is part of a communication network having a topology, detecting a compromised ability to forward a flow of packets originating from a source endpoint to a destination endpoint. In response to detecting the compromised ability, the first network switch identifies, based on the topology, a second network switch that lies on a current route of the flow, and also lies on one or more alternative routes from the source endpoint to the destination endpoint that do not traverse the first network switch. A notification, which is addressed individually to the second network switch and requests the second network switch to reroute the flow, is sent from the first network switch.

Abstract: A method and user node for maintaining a connection with a network node when operating in a multi-carrier mode using a first filter configuration to receive multiple frequency carriers simultaneously for downlink communication. The user node applies a mode switching scheme comprising first intervals for the multi-carrier mode and second intervals for a single carrier mode using a second filter configuration to receive a single carrier for the downlink communication. In this case, the user node switches temporarily from the multi-carrier mode to operate in the single carrier mode during the second intervals according to the mode switching scheme. Thereby the user node is enabled to maintain the connection by receiving messages and/or control signalling from the network node over the single frequency carrier during the second intervals, for example when the multi-carrier mode is highly disturbed by interference.

Abstract: There is provided a method in a packet based network system for node-to-node transmission of data packets comprising timing packets and non-timing packets, which is directed to a mechanism for providing a delay variation compensation in a timing system or timing sensitive signal transport in a packet based network without participating in the timing signaling of the timing packets or timing sensitive packets themselves. The method comprises associating the data packets with different levels of transmission priority Pr, Pl, assigning highest (or highest available) transmission priority Pr to the timing packets, separately queuing the timing packets in different buffers 401, 402, and providing first opportunity transmission of the timing packets regardless of transmission priority level of non-timing packets waiting to be transmitted. The advantage of the method is that timing-sensitive traffic thereby experiences reduced buffer delay variations.

Abstract: Methods, systems, and computer readable media can be operable to facilitate the use of a station as a proxy for scanning one or more wireless channels. Upon a determination that a currently utilized wireless channel has become impaired, an access point may identify one or more idle wireless stations and may request that the one or more idle wireless stations perform a scan of one or more other wireless channels. The identified wireless station(s) may perform a scan of one or more other wireless channels and may provide an indication of the current level of congestion on each respective wireless channel to the access point. Based on the indication of the current congestion levels of each wireless channel, the access point may determine whether a more advantageous channel is available. If a more advantageous channel is available, the access point may tune to the more advantageous channel.

Abstract: An apparatus, such as a network element, comprises a receiver to receive a plurality of packets. A memory stores instructions and forms a first and second set of virtual queues to store the plurality of packets. A processor having one or more cores with one or more packet classifiers provides a classification of a packet in the plurality of packets. The processor in communication with the memory executes instructions to transfer the packet from the receiver to a virtual queue in the first set of virtual queues based on the classification. The processor also transfers the packet from the virtual queue to a transmitter based on a demand rate value and supply rate value associated with the virtual queue.
