Abstract: A method and system for Air-To-Ground communications allowing integration of the aircraft communication with a terrestrial cellular communications network. The solution is carried out in the aircraft so any existing standard terrestrial cellular communication network may be used without requiring any modification. The constraints due to the special aircraft conditions (speed and height) are efficiently solved, allowing broad interoperability with the cellular communications network, satisfying the increasing high speed data demand. Specifically, in order to solve the handover constraints the aircraft antenna will create at least two radiation patterns: one for maintaining the current connection with the serving base station and another one or more to search the next suitable best station for handover.

An example method generally includes determining one or more narrowband regions partitioned from wider system bandwidth for communicating with a base station, determining resources, within the one or more narrowband regions of a first subframe, for transmission of sounding reference signals (SRS) by the UE, deciding whether or not to transmit SRS on the determined resources of the first subframe, and transmitting or not transmitting the SRS on the determined resources of the first subframe based on the decision.

Abstract: Methods, systems, and devices for wireless communication are described. Data may be received during transmission time intervals (TTIs) that have a short duration relative to other TTIs. The short-duration TTIs may occur within or overlap a longer duration TTI, such as a subframe. Feedback responsive to the data may be generated and assigned for transmission during an uplink TTI according to a feedback timing or delay, which may be selected to reduce latency or balance the payload size of uplink messages sent during the assigned uplink TTI. Data and feedback assignments in short-duration TTIs may be configured based on a time division duplexing (TDD) configuration for some TTIs (e.g., subframes). TTIs that are a Long Term Evolution (LTE) subframe, an LTE slot, and a duration of two LTE symbol periods may be supported. Portions of special TTIs may be used for transmissions according to shorter-duration TTIs.

Further, synchronization broadcast transmission including the at least one SSB is generated, and the generated synchronization broadcast transmission is transmitted at the at least one candidate transmission location in a beam sweeping manner.

In one example, an initial sidelink communication is transmitted which includes an indication of resources reserved for a subsequent sidelink communication. A transmission restriction is applied for the subsequent sidelink communication based on a transmission characteristic associated with transmitting the initial sidelink communication. The subsequent sidelink communication is then transmitted according to the transmission restriction.

Abstract: An automated registration service supported on an application server that interoperates with an IMS (IP Multimedia Subsystem) core network is configured to dynamically register and deregister devices that are all associated with one or more commonly-utilized phone numbers. The service may assign the phone number to registered devices and, in contrast, un-assign the phone number from deregistered devices. The registration and deregistration of the devices may occur based on the amount of interaction with the device and other real-time contextual information. Furthermore, the automated registration service intelligently determines which registered devices to forward incoming video and/or audio calls to based on various contextual information, including the capabilities of device, identified location of a user, user preferences, etc. By intelligently selecting which devices should receive an incoming call, unnecessary use of bandwidth, data, and resources (e.g., battery power) can be reduced.

Abstract: Techniques are described for providing fast reroute for traffic in EVPN-VXLAN. For example, a backup PE device of an Ethernet segment is configured with an additional tunnel endpoint address (“reroute tunnel endpoint address”) for a backup path associated with a second split-horizon group that is different than a tunnel endpoint address and first split-horizon group for another path used for normal traffic forwarding. The backup PE device sends the reroute tunnel endpoint address to a primary PE device of the Ethernet segment, which uses the reroute tunnel endpoint address to configure a backup path to the backup PE device over the core network. For example, the primary PE device may install the reroute tunnel endpoint address within its forwarding plane and one or more operations to cause the primary PE device to encapsulate a VXLAN header including the reroute tunnel endpoint address when rerouting the packet along the backup path.

Abstract: A transmitting device maps complex valued symbols in sequence to physical resource blocks for a sidelink transmission. The transmitting device reserves a first symbol of a subframe, where resource elements in the first symbol of the subframe are not considered in mapping the complex valued symbols to the physical resource blocks for the sidelink transmission. The transmitting device transmits the sidelink transmission after mapping the complex valued symbols to the physical resource blocks. A receiving device receives the sidelink transmission and decodes the sidelink transmission to determine complex valued symbols that are mapped in sequence to physical resource blocks of the sidelink transmission, where the complex valued symbols are not mapped to resource elements in a first symbol of a subframe.

Abstract: A data modulation and device and demodulation device for the multicarrier system are provided. The data modulation method includes: performing different cyclic shifting on data sequences of L continuous symbols respectively, L?2; and modulating the cyclically shifted data sequences by use of a waveform function, an independent variable range of the waveform function being greater than or equal to a symbol interval of the L modulated symbols. The technical solution solves the technical problems in which the related art is not compatible with a LTE system or effectively suppressing out-of-band leakage or flexibly adjusting a symbol interval to adapt to different channel environments and exhibits poor demodulation performance, thus achieving effective suppression of the out-of-band leakage, having higher compatibility with the LTE system and improving demodulation performance and flexibility of adjusting a symbol interval by simple cyclic shifting.
