  • Patent number: 10004078
    Abstract: A network node (600), a wireless device (602) and methods for controlling a radio communication using carrier aggregation. The wireless device (602) sends (6:1) UE capabilities to the network node (600), indicating a maximum capability limit per component carrier and a total maximum capability limit across all component carriers to be used in the radio communication. The network node (600) further selects (6:2) a number of component carriers to be used by the wireless device, and configures (6:3) radio features on the selected component carriers based on the received UE capabilities. The network node (600) then signals (6:4) the selected number of component carriers and the configured radio features to the wireless device (602) for use in the radio communication (6:5). Thereby, the network node (600) can utilize the full capabilities of the wireless device (602) when configuring the radio features while still respecting both the maximum capability limit per carrier and the total maximum capability limit.

  • Patent number: 9984144
    Abstract: A method for classification includes extracting respective classification keys from a collection of data items and receiving a corpus of rules for matching to the classification keys. At least some of the rules include masked bits in addition to the unmasked bits. Rule patterns are extracted from the corpus, defining different, respective sequences of masked and unmasked bits to which one or more of the rules conform. The rule patterns are grouped into extended rule patterns, such that the respective set of unmasked bits in any rule pattern is a superset of the unmasked bits in the extended rule pattern into which it is grouped. Rule entries corresponding to the rules are computed using the extended rule patterns and are stored in a random access memory (RAM). The data items are classified by matching the respective classification keys to the rule entries in the RAM.

  • Patent number: 9979652
    Abstract: The present invention is related to an intermediate node, an end node, and method for avoiding latency in a packet-switched network. According to the invention, the maximum bandwidth per flow is determined locally and transferred from the sending node to the receiving node. At each node, the information is updated if a lower local value is computed. By adjusting the transmission rate based on the maximum bandwidth per flow receiving at the receiving node, the link capacity can be optimally utilized and congestion can be minimized.

  • Patent number: 9961582
    Abstract: A system and method for providing an eNodeB with the flexibility to configure a Channel State Information (CSI) report to match a specific Coordinated Multipoint (CoMP) transmission hypothesis, which is a candidate for a downlink transmission to a User Equipment (UE) is disclosed. A UE receives, from the eNodeB, a configuration message that specifies a CSI report. The CSI report is specified by a particular interference hypothesis and a particular desired signal hypothesis corresponding to data transmission over at least one effective channel characterized by a specific reference signal. The UE estimates interference according to the interference hypothesis, and/or estimates at least one effective channel by performing measurements on the specific reference signal, and determines a CSI report based on the interference estimation and on the estimated effective channel. The UE also transmits the CSI report to the eNodeB.

  • Patent number: 9955461
    Abstract: PUCCH resource determination for HARQ-ACK transmission in response to ePDCCH-scheduled PDSCH or ePDCCH-indicated SPS release in a TDD radio communication system. Downlink control information (DCI) is received in a downlink subframe via an Enhanced Physical Downlink Control Channel (ePDCCH). A resource index for a Physical Uplink Control Channel (PUCCH) resource is determined, based on the lowest enhanced Control Channel Element (eCCE) index of the received DCI, a device-specific offset value, and an index i that identifies the downlink subframe in a pre-determined set of one or more downlink subframes associated with an uplink subframe. The PUCCH resource is determined according to a formula that results in a sequential allocation of PUCCH resources in the uplink subframe with respect to the downlink subframes associated with the uplink subframe, for each of a plurality of sets of ePDCCH resources. HARQ feedback is transmitted in the uplink subframe, in the indexed PUCCH resource.
