    Abstract: A method of operating a distributed MIMO system is disclosed. The distributed MIMO system is configured to serve a plurality of wireless communication devices (u1, . . . , uN). The distributed MIMO system comprises a number of access points (A1, . . . , AK), each comprising a time circuit (180) configured to keep track of a local time of the access point (A1, . . . , AK). The method comprises performing (210) an intra-group synchronization procedure for a group (G1) of at least three access points (A1-A3). The intra-group synchronization procedure comprises, for each access point (Ai) in the group (G1), transmitting (Ti), from that access point (Ai), a synchronization signal and obtaining (Oi) a transmission time indicator indicating a transmission time of that synchronization signal in the local time of that access point (Ai).

  • Patent number: 11563641
    Abstract: A traffic shifting system is described to shift traffic away from one or more network devices or interfaces. The system ensures that traffic can be safely shifted off of a network device before the shifting occurs. The method is described as broken into several phases, such as a discovery phase, a pre-check phase, a shifting phase, and a post-shift phase. Before shifting occurs, the discovery phase is used to obtain network topology and configuration information. In the pre-check phase, that information is interrogated so that a shifting can be performed without negatively impacting the network. If the pre-check phase is passed, then the network shifting can occur through adjustment of configuration parameters, such as a cost parameter associated with an interface on any devices for which traffic is being shifted. Finally, in the post-shift phase, checks are performed to ensure traffic is shifting away from the network device.

  • Patent number: 11546848
    Abstract: Methods and techniques are described for initiating a periodic and triggered location in a target UE. After an LCS Client requests initiation of periodic and triggered location reporting from the UE, two intermediate responses are returned by a network. A first response indicates that the periodic and triggered location request has been received and accepted by the network. A second response indicates that periodic and triggered location has been activated in the UE. Additionally, a periodic and triggered location request may include a maximum event sampling interval and a maximum reporting interval and one or more location triggers. The maximum event sampling interval can limit UE power consumption and the maximum reporting interval can detect when periodic and triggered location is no longer active in a UE. The location triggers may include periodic reporting, reporting using area events or reporting based on UE motion.

  • Patent number: 11528230
    Abstract: According to the present invention, in order to allow enhancement in the transmitting efficiency of a transmission system using link aggregation, if the bandwidth usage rates of the physical links constituting the LAG are imbalanced, identification information of a factor packet that serves as a factor for the imbalance is estimated on the basis of a distribution rule and the second information about a data amount. In addition, the factor packet is distributed to physical links to which the factor packet is distributed, and a packet that is not the factor packet is distributed according to the distribution rule, which is based on, for each of the physical links constituting the LAG, a remaining bandwidth obtained by subtracting the usage bandwidth of the factor packet distributed to said physical link from the maximum available bandwidth of said physical link.
