  • Patent number: 10660055
    Abstract: In one aspect of the teachings herein, a transmitter transmits synchronization signals according to one or more defined transmission characteristics that enable a receiver to distinguish the type of transmitter and/or the type of carrier used to convey the synchronization signals. Different types of transmitters reuse at least some of the same synchronization signal sequences and generation algorithms, but use different transmission parameters to impart one or more recognizable characteristics to the transmitted synchronization signals. In turn, an appropriately configured receiver “knows” which characteristics are associated with which transmitter and/or carrier types. For example, wireless devices operating in a wireless communication network transmit device-generated synchronization signals that reuse at least some of the same sequences used by network base stations for the transmission of network synchronization signals.

  • Patent number: 10643465
    Abstract: A framework for precision traffic analysis estimates dilemma zone activity to dynamically adjust phase cycle timing for improved efficiency of traffic flow at a roadway intersection. The framework identifies a traffic detection area at or near a traffic intersection, and detects objects in the traffic detection area from sensors located proximate to the traffic intersection. The framework then correlates lapsed phase cycle times for the traffic signal with associations between object characteristics and known speed characteristics for the roadway for a determination of whether there is dilemma zone activity for the remainder of that phase cycle. The framework then determines whether to adjust a timing of the current phase cycle.

  • Patent number: 10645624
    Abstract: Various embodiments are generally directed to improved channel quality information feedback techniques. In one embodiment, for example, an evolved node B (eNB) may comprise a processor circuit, a communication component for execution by the processor circuit to receive a channel quality index for a physical downlink shared channel (PDSCH), the channel quality index associated with a defined reference resource, and a selection component for execution by the processor circuit to select a modulation and coding scheme (MCS) for transmission over the PDSCH of user equipment (UE) data in one or more resource blocks, the selection component to compensate for a difference between a cell-specific reference signal (CRS) overhead of the defined reference resource and a CRS overhead of the one or more resource blocks when selecting the MCS. Other embodiments are described and claimed.

  • Patent number: 10638289
    Abstract: Some services offered by M2M service layers will have contact information that will be used in order to interact with applications. For example, a service layer may need to send notification messages to an application. To do this, the service layer relies on stored contact information to know how to reach the application. If the device hosting the application moves and the application changes its contact information, then the contact information that is in the service layer is stale. As a result, these services will be inefficient, or in some cases, fail altogether. Embodiments described herein provide systems and methods to enable mechanisms to update stale contact information in M2M service layers.

  • Patent number: 10637606
    Abstract: The present specification provides an operation method of a base station for transmitting and receiving a signal using non-orthogonal multiple access (NOMA) in a wireless communication system. The method comprises the steps of: setting a first modulation scheme and a first transmission power for a first signal to be transmitted to a first user equipment; setting a second modulation scheme and a second transmission power for a second signal to be transmitted to a second user equipment; overlapping the first signal and the second signal; and transmitting a signal obtained by overlapping, wherein the transmission of the overlapped signal uses an overlapping constellation defined in advance or configured by a predetermined notation.

  • Patent number: 10630762
    Abstract: A technology is described for emulating a multicast network. An example method may include receiving a data transaction request at a data store service. The data transaction request may contain a network packet for multicast distribution to destination clients, and the data transaction request may be received from a source client having a multicast conversion driver configured to convert the network packet into a data transaction request format. A determination may be made that the data transaction request is a multicast request to distribute the network packet to the destination clients. Having determined that the data transaction request is a multicast request, destination clients that are subscribed to receive the multicast group communication may be determined. A data record containing the network packet may be distributed to the destination clients, where the destination clients have the multicast conversion driver configured to convert the data record to the network packet.

  • Patent number: 10631298
    Abstract: A data transmission method is provided. The method comprises: reserving a first channel and a second channel, where the first channel is used for transmitting data and the second channel is used for transmitting ACKs; sending data to a receiving end on the first channel that is reserved; receiving an ACK that is sent by the receiving end and corresponds to the data on the second channel that is reserved and determining whether the data needs to be cached based on information carried in the ACK; and if the information carried in the ACK indicates that the receiving end has correctly received the data, clearing the data that is cached by a sending end. Through separate transmission of the data and the ACK, an efficiency problem of the sending end in providing MAC in a wireless system in a condition of a limited cache capacity is resolved.

  • Patent number: 10623955
    Abstract: A method and apparatus for providing fallback data services over a Wi-Fi network is described. A request to enable access to new data sessions for wireless terminals in a zone covered by a Wi-Fi network node is received upon failure of 3GPP radio in that zone. When a request for a new data session from a WT is received, the MAC address of the WT is added to a list of authorized users. The MAC address of the WT is sent to Wi-Fi network nodes of adjacent zones such that the WT can have continuous service as it moves between zones. When a Wi-Fi network node currently serving the WT receives an indication that the WT data session is terminated, a message is sent from the Wi-Fi network node currently serving the WT, to nodes of adjacent zones to remove the MAC address of the WT from the list of authorized users.
