Abstract: Techniques for selecting a wireless connection based on network metrics are discussed herein. For example, user equipment (UE) can be connected to a Wi-Fi network. The UE may test the Wi-Fi connection to determine metrics associated with the Wi-fi connection. The UE may compare the metrics to a speed and/or bandwidth threshold. If the Wi-fi connection speed is below a threshold, the UE may determine metrics associated with a cellular connection to determine whether to switch to a different cellular connection. If a first metric of the candidate cellular connection is above a threshold (e.g., a power level threshold), the UE can determine a speed or bandwidth of the connection. If the speed or bandwidth is above a threshold, the UE can attach to the cellular connection and can send and/or receive data using the newly established connection.

Abstract: Bi-directional tunnel probing in a network may be extended to multi-realm networks, providing bi-directional probing in a multi-realm network. Bi-directional probing uses probe packets with a forward tunnel label, a reverse tunnel label, and an IP packet header. Bi-directional probing in a multi-realm network uses a forward tunnel label, an SID, a reverse tunnel label, and an IP packet header. Penultimate hop popping strips the outermost labels in a specific order. The SID gets the probe packet back into the originating realm, and the reverse tunnel label returns the probe packet along the reverse direction of the tunnel. No SID is needed for intra-realm probing, and the IP packet header is used to return the probe packet if the reverse tunnel label is absent.

Abstract: New reverse direction (RD) protocols for EHT devices during reserved target wait time (R-TWT) service periods (SPs). In this protocol the R-TWT scheduling AP does not have to trigger the RD initiator when it performs as the RD responder, and can trigger TB PPDU(s). In addition, the RD initiator is enabled to inform the RD initiator to inform its non-AP peer STA about the R-TWT information in the transmitted RD PPDU. The RD initiator is enabled to send a new MU RD PPDU to both the R-TWT scheduling AP and the non-AP peer STA, which allows the AP to quickly takeover scheduling if the non-AP peer STA is a non-RTWT member and has limited access the in current ongoing R-TWT SP.
