  • Patent number: 11089558
    Abstract: A resynchronization signal (RSS) may extend across multiple physical resource blocks (PRBs) or subframes, which may cause the RRS to be scheduled to overlap with other downlink transmissions. Methods, systems, and devices for wireless communications are described for management of RSS and one or more other transmission types that may have overlapping wireless resources with the RSS. If one or more other downlink transmissions are scheduled for resources that overlap with resources scheduled for an RSS transmission, the UE may receive the RSS transmission or the one or more other downlink transmissions, or a combination thereof, based on a prioritization of the transmission types of the one or more other downlink transmissions relative to RSS.

  • Patent number: 11039497
    Abstract: A core network receives data from at least one of an AF, a DN, or a UE. A UPF having small data capability processes the data for transport with a low overhead and without initiating a bearer set up protocol. The data may be transported between the UE and the UPF as an RRC payload over a NAS protocol. The data may be received from an AF or DN external to the core network and may be processed to transport the data to the UE based as an RRC payload. The data may be received as uplink data from a UE, e.g., in an RRC payload. The UPF may process the RRC payload to obtain the data and may transport the data to the AF or DN. The UPF may perform IP header compression, data encryption, and/or buffering of data for a UE in an idle mode.

  • Patent number: 11039372
    Abstract: Methods, systems, and devices for wireless communication are described. A wireless communications system may support techniques for efficient communication between a user equipment (UE) and different entities (or functions) of a core network. Specifically, the UE may interact with a single entity (or function) of a core network (e.g., an access and mobility management function (AMF)), and messages intended for other entities (or functions) may be routed appropriately by this entity. For example, an AMF may receive a message from a UE intended for another entity (or function) of the core network, and the AMF may transmit (or route) the message to the entity (or function). Similarly, the AMF may receive a message from another entity (or function) of the core network, and the AMF may transmit (or route) the message to the UE.

  • Patent number: 11038819
    Abstract: Technologies for distributing network packet workload are disclosed. A compute device may receive a network packet and determine network packet extrinsic entropy information that is based on information that is not part of the contents of the network packet, such as an arrival time of the network packet. The compute device may use the extrinsic entropy information to assign the network packet to one of several packet processing queues. Since the assignment of network packets to the packet processing queues depend at least in part on extrinsic entropy information, similar or even identical packets will not necessarily be assigned to the same packet processing queue.
