Abstract: Methods and techniques are described for supporting satellite wireless by a user equipment (UE) using satellite acquisition information. A UE may obtain (e.g., from an AMF or gNB) acquisition information for satellite cells supporting access to a PLMN. The UE may enter an inactive state with no radio access, may later leave the inactive state, find a preferred satellite cell based on the acquisition information and access the satellite cell (e.g., camp on the cell or connect to the PLMN using the cell). The acquisition information may indicate satellite cells available at one or more predefined times for a known location of the UE or may enable a satellite cell to be found for any UE location at any time. The acquisition information may also provide timing, frequency and other information to enable a UE to access a satellite cell with reduced latency and reduced power consumption.

Abstract: The disclosure relates to a method for transmitting sensor data from multiple sensors to a satellite. In a first phase, which is designated as a registration phase, the satellite registers the sensors in question and allocates each sensor a time window for transmitting the respective sensor data, and in a second phase, which is designated as a transmission phase, the satellite requests the sensor data in the individual sensors in a controlled manner, e.g., according to a list generated by the satellite during the registration phase. Thus, it is possible for satellites to access a ground-based sensor system in an optimized and self-learning manner.

The invention also allows for a flexible and dynamic change of the EPC Nodes dedication based on operator's configuration and policy. Additionally, the invention allows for DCN access restriction control by broadcasting of the supported DCN Types by the RAN Node.

Abstract: A computing device (such as a computer gaming console) uses only a single radio to concurrently communicate with a wireless network access point and wireless client devices such as game controllers or peripherals. To establish and maintain both a high-throughput link with the access point, and a low-latency link with the client device(s), the single Wi-Fi radio of the computing device is configured to periodically switch between a channel used for the high-throughput link and a different channel that is used for the low-latency link—thus implementing a combination of frequency division multiplexing (FDM) and time division multiplexing (TDM). The console may use aspects of the Wi-Fi protocol standard to ensure that periodically switching its single radio between the two channels is accomplished while maintaining reliable communication on both channels.
