  • Patent number: 10674426
    Abstract: A method may be provided to operate a CU node that is coupled with first and second DU nodes. Communication is provided between the CU node and a mobile communication device through the first DU node over a first radio link. A message is received at the CU node from the first DU node that the radio link is temporarily unavailable. Responsive to receiving the message, communication between the CU node and the mobile communication device through the first DU node is suspended, wherein configuration of the first DU node to serve the mobile communication device using the first radio link is maintained. While suspending communication between the CU node and the mobile communication device through the first DU node, communication may be provided between the CU node and the mobile communication device through the second DU node over a second radio link.

  • Patent number: 10673759
    Abstract: Systems, devices, and techniques for providing content via a bandwidth-conserved connection to a client device is described herein. Content can be encoded at reduced rate in response to being presented with a bandwidth-conserved connection. When the encoded content is received at a network provider, the network provider can determine a transmission pattern to transmit the encoded content to the client device. The transmission pattern can include transmission periods where the encoded content is transmitted at a maximum transmission rate, followed by periods where no encoded content is transmitted. Thus, although an instantaneous transmission rate approaches a maximum transmission rate of a network, the average transmission bandwidth provided to the client device can be limited, thereby reducing congestion in the network. Further, a radio element of the client device can enter a low power state when no encoded content is to be transmitted, thereby reducing power consumption at the client device.

  • Patent number: 10666564
    Abstract: Entropy in routing tables may be increase to perform packet forwarding. Hash tables that store forwarding routes may be divided into multiple hash table segments. Forwarding routes may be stored across the hash table segments in different route segments. When looking up route segments to identify a forwarding route for a destination address of a network packet, digest values generated for previous route segments may be used to determine hash key values to identify hash table entries in a different hash table segment. The forwarding route may be identified according to the hash table entries located based on the digest values for previous route segments.

  • Patent number: 10660075
    Abstract: Embodiments of the present disclosure provide a channel state information (CSI) sending method, a CSI receiving method, a terminal, and a base station. The terminal selects a target CSI process from N CSI processes. The terminal sets a CSI reporting mode corresponding to the target CSI process, and sends, based on the CSI reporting mode, a CSI corresponding to the CSI process. The terminal can set a CSI reporting mode corresponding to a CSI process, and send, based on the set CSI reporting mode, a CSI corresponding to the CSI process. However, in the prior art, only the base station configures a CSI reporting mode corresponding to each CSI process. Therefore, flexibility is increased.

  • Patent number: 10652900
    Abstract: Embodiments herein relate to a method performed by a network node for enabling channel estimation in a wireless communications network. The wireless communications network includes at least a first and a second Access Point, AP, having overlapping cells using contention-based transmission resources of the same frequency. The first network node controls the first AP to transmit information indicating that wireless devices served by the first AP are not to contend for the contention-based transmission resources when the second AP is transmitting a Null Data Packet, NDP. Then, the first network node controls the second AP to transmit a NDP. Embodiments of the first network node are also described. Embodiments herein also relate to a method performed by a wireless device for enabling channel estimation in a wireless communications network, and embodiments of the wireless device.

  • Patent number: 10645727
    Abstract: A transmitting device may determine that a first neighbor device is communicating with a second neighbor device based on a signal received from the first device (e.g., a request-to-send (RTS) signal) during a listen-before-talk (LBT) period. The transmitting device may also identify a direction of the second neighbor device (e.g., based on signals received during a previous LBT period), and determine the amount of interference that a directional transmission may cause at the second neighbor device. The determination may be based on whether the transmission direction (i.e., a beam direction of a directional transmission) is in a same direction as the second neighbor device. If the interference level is below a threshold, the transmitting device may perform the transmission despite receiving the signal during the LBT period. If the interference level is above the threshold, the transmitting device may refrain from transmitting.

  • Patent number: 10638377
    Abstract: A secondary base station (2) receives an SeNB addition request message (302) from a second master base station (3) while providing a radio terminal (4) with a secondary cell group (SCG) for DC in cooperation with a first master base station (1). If the SeNB addition request message (302) explicitly or implicitly indicates that a master base station in DC for the radio terminal (4) is to be changed from the first master base station (1) to the second master base station (3), the secondary base station (2) considers that the SeNB addition request message (302) requests modification of the SCG that has already been configured. It is thus, for example, possible to contribute to performing a procedure for changing a master base station in Dual Connectivity (DC) by using existing inter-base station interface procedures and inter-base station signaling messages.

  • Patent number: 10602565
    Abstract: Method performed by a first communication device (511) for performing one or more actions to resolve a state mismatch between the first communication device (511) and a second communication device (512) operating in a communications network (500). The first communication device (511) searches (601, 704) for one or more transmissions from the second communication device (512) that are indicative of a state mismatch between the first communication device (511) and the second communication device (512). Upon detection of the one or more transmissions, the first communication device (511) performs (602, 705) one or more actions to resolve the state mismatch. The performing (602, 705) of the one or more actions is according to one of: a) a current state of the second communication device (512) and b) a transition to a state different from a current state of the first communication device (511).

  • Patent number: 10594755
    Abstract: A network system and the method is described that splits media identification logic and media classification and/or general data session processing/management logic into separate controllers (e.g., between the local controllers and a service controller). By separating media identification logic and media classification logic (or general media processing/management logic), the system and method allows for greater flexibility and scalability in a network system employing a service controller. In particular, by allowing the local controllers to perform media identification and to construct a single packet that characterizes/describes a media session, the system avoids the need to transmit multiple data packets of a media session to the service controller for classification of the session.
