  • Patent number: 10887879
    Abstract: Methods and devices are described for encoding and decoding control information that has been modulated based on one or more identifiers of the transmitter and/or receiver. Some embodiments describe scrambling sequence design for multi-mode block discrimination on downlink control information (DCI) blind detection. Separate scrambling masks may be applied to disparate bit fields within a coded DCI message, wherein each of the scrambling masks is derived from a unique identifier associated with either the transmitter or the intended receiver. The scrambling masks may be used by the receiver to perform early termination of the decoding process, to mitigate intercell interference, and to verify that the receiver is the intended receiver.

  • Patent number: 10855593
    Abstract: A local network device of a network switching system determines, based on a first set of received packets that contain markings indicating congestion at one or more other network devices in the network switching system, one or more respective congestion levels of one or more network paths through the network switching system. The local network device selects, based on determined congestion levels, network paths via which a second set of received packets are to be forwarded for load balancing. The local network device alters header information in the second set of received packets, the altered header information to be used by other network devices in the network switching system to make network path selections so that the second set of received packets are subsequently forwarded responsively to the altered header information along the selected network paths within the network switching system.

  • Patent number: 10827375
    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.
