The first set of DCI includes independent DL assignments allowing the first CoMP eNB to perform independent scheduling of a PDSCH associated with the first CoMP eNB. A second CoMP eNB constructs a second set of DCI. The second set of DCI is independently constructed by the second CoMP eNB. Furthermore, the second CoMP eNB transmits the second set of DCI to the CoMP UE. The second set of DCI includes independent DL assignments allowing the second CoMP eNB to perform independent scheduling of a PDSCH associated with the second CoMP eNB.

  • Patent number: 9906454
    Abstract: In various example embodiments, a system and method are presented for a bandwidth (BW) management system. The BW management system accepts, on behalf of a receiving host, data packets for a first individual flow at a flow rate sent by a sending host. The bandwidth management system manages bandwidth by traffic classes representing collections of flows associated with nodes in a hierarchical bandwidth tree (HBT). The first individual flow is included within the collection of individual flows associated with one or more of the traffic classes. The BW management system controls the rate at which the sending host is transmitting the data packets for the first individual flow using a sliding window protocol by managing the bandwidth utilization of the nodes to conform to bandwidth limits assigned to the nodes. The BW management system receives the data packets for the first individual flow at an adjusted flow rate based on the sliding window protocol.

  • Patent number: 9894692
    Abstract: For transmitting data between a node (100) of a mobile network and a further node (200), the further node sends downlink data packets to the node (100) of the mobile network. The downlink data packets carry a destination address corresponding to a user equipment (10) connected to the mobile network. For implementing an inband data channel between the node (100) of the mobile network and the further node (200), the further node (200) inserts data destined to the node (100) of the mobile network into at least one of the downlink data packets and marks this downlink data packet as including data destined to the node (100) of the mobile network. The node (100) of the mobile network receives the downlink data packets from the further node (200) and identities, on the basis of the marking, the least one downlink data packet including data destined to the node (100) of the mobile network. The node (100) of the mobile network then extracts the data from the identified downlink data packet.

  • Patent number: 9871732
    Abstract: Enhancing performance in a multicasting system. Flow rates in a multicasting system are monitored as system characteristics change. The multicasting system is operated based on a first mapping between data flows and multicasting groups. Data is disseminated by way of the mapping to subscribers to one or more of the data flows. The flow rate thresholds of satisfied flows are decreased to minimize the difference between the flow rate thresholds and respective target transmission rates of the satisfied flows, as the system's feasible data transmission workload is maintained with respect to subscriber reception rate capacities. The flow rate thresholds of unsatisfied flows are increased to minimize the difference between the flow rate threshold and respective target transmission rates for the unsatisfied flows and to limit occurrences of data transmission delays or losses, as the system's feasible data transmission workload is maintained with respect to subscriber reception rate capacities.

  • Patent number: 9860753
    Abstract: A method and apparatus for allocating bandwidth in a broadband wireless communication system is disclosed. One embodiment uses a self-correcting bandwidth request/grant protocol. The self-correcting bandwidth request/grant protocol utilizes a combination of incremental and aggregate bandwidth requests. CPEs primarily transmit incremental bandwidth requests to their associated base stations, followed by periodic transmissions of aggregate bandwidth requests. The use of periodic aggregate bandwidth requests (that express the current state of their respective connection queues) allows the bandwidth allocation method and apparatus to be “self-correcting”. Another embodiment utilizes an abridged bandwidth request/grant protocol to allocate bandwidth. The abridged bandwidth request/grant protocol system utilizes padding packets to request a reduction in bandwidth allocation to a CPE. A base station modem alerts a base station CPU when the BS modem receives a padding packet from a CPE.

  • Patent number: 9860920
    Abstract: A method of operating a mobile station requesting uplink access from a base station subsystem may include transmitting an access request to the base station subsystem, and delaying looking for a response matching the access request according to a delay interval. A response time window (RTW) may be initiated after the delay interval. During the response time window, the mobile station may look for an assignment message transmitted from the base station subsystem and matching the access request without looking for an assignment message matching the access request during the delay interval.

  • Patent number: 9853800
    Abstract: Method and radio node (500) for controlling a change of communication mode between transmit mode and receive mode according to a Time Division Duplex, TDD, scheme. The radio node has at least two parallel branches (504, 06) for transmission and reception of radio signals, wherein the branches currently operate in a first communication mode. The radio node obtains one or more indication signals (S1A, S1B) generated by one or more of the branches to indicate that the first mode has been turned off. When it is determined that the first communication mode has not been turned off in a faulty branch, e.g. by not receiving an indication signal in time from that branch, the first mode is disabled in the faulty branch, and/or the faulty branch is reported to a supervision center (510). Thereby, it can be discovered when one of the branches is misaligned or otherwise faulty and suitable actions can be taken for repairing or replacing the faulty branch.

  • Patent number: 9825885
    Abstract: Methods and systems for a more efficient transmission of network traffic are provided. According to one embodiment, presence of outbound payload data, distributed across a first and second payload buffer, within a user memory space of a network device that has been generated by a user process is determined by a bus/memory interface or a network interface unit. The payload data is fetched by performing direct virtual memory addressing of the user memory space including mapping virtual addresses of the payload buffers to corresponding physical addresses, including: (i) when the payload buffers are noncontiguous, then retrieving the outbound payload data with reference to multiple buffer descriptors having starting virtual addresses of the payload buffers and (ii) when they are contiguous, then retrieving the outbound payload data with reference to a single buffer descriptor. The outbound payload data is then segmented across one or more TCP packets.
