Abstract: A contending radio node is configured for attempting contention-based random access. The contending radio node obtains a timing advance sequence that is susceptible to contention. The contending radio node transmits, using the same transmission advancement timing, the timing advance sequence and a contention-resolving identity to a recipient radio node. Responsive to that transmission, the contending radio node receives a response signal that indicates a contention-resolving identity and a timing advance. The contending radio node resolves any contention in its favor when the contention-resolving identity indicated by the response signal corresponds to the contention-resolving identity that the contending radio node transmitted. The contending radio node, responsive to resolving the contention in its favor, adjusts its transmission advancement timing according to the timing advance indicated by the response signal.

Such methods include sending to the UE a further control message for activating the configured set of SP-SRS resources. The further control message includes information identifying an SP-SRS resource of the set of SP-SRS resources to be activated, and an indication of the identified SP-SRS resource's spatial relation with a further resource that is not associated with the particular serving cell. The indication comprising an identity of a further serving cell that is different from the particular serving cell and that is associated with the further resource. Other embodiments include complementary methods for a UE.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may support multiple radio access technologies (RATs). The UE may communicate using both a Long Term Evolution (LTE) connection for control signaling and a New Radio (NR) connection for data signaling in a non-standalone (NSA) mode. However, if the UE uses a data rate below a threshold, the NR connection may be inefficient. To reduce processing overhead, the UE may fall back to using the LTE connection for data communications. For example, the UE may delay or abort adding an NR connection based on the data rate. In some examples, the UE may transmit a fake report or a fake uplink message to trigger dropping an NR connection. Additionally or alternatively, the UE may indicate a preferred mode of operation to the network indicating a preference for communicating data via an LTE connection.

Abstract: Techniques for configuring a network system that includes a cellular network and a Wi-Fi network to support location-based resource allocation are discussed herein. To cover regions with weak cellular signal and/or with densely packed devices (e.g., a stadium during a football game), a network may use both cellular and Wi-Fi networks to provide coverage. In some examples, the system may configure a base station and a user device to enable automatic authentication of the user device to access a new Wi-Fi network. In response to a service request from the user device, the system may determine whether the Wi-Fi network can handle the service or switch a serving connection. The system may also determine whether the Wi-Fi network includes location-based applications that should be rendered at the user device.

Abstract: A wireless access point software application, including multiple software modules, dynamically determines the interference level of each channel. The application determines that a new channel is better suited to serve an RTC/RTE application over the present channel based on the interference levels and a set of interference measure thresholds. The application automatically creates a new basic service set on the new channel and associates the RTC/RTE device running the RTC/RTE application with the new basic service set. The application further refuses to associate the RTC/RTE device with the previous channel when the interference level on the new channel remains low based on a second set of interference measure thresholds. In addition, the application allows additional RTC/RTE devices to join the new basic service set with the first RTC/RTE device when the interference level on the new channel remains low based on the second set of interference measure thresholds.
