Abstract: A multi-protocol network and methods for operating the same are provided. The method begins with establishing a wireless-connection between a first transceiver in a first device and a second-transceiver in a second device using a wireless-protocol. First, wired-protocol packets and non-packet data are received and converted in the first device to second-packets compatible with the wireless-protocol by inserting synchronization-bits non-packet data in a preamble. This is initiated by sensing arrival of the preamble without waiting for a start of data. The second-packets are transmitted from the first transceiver to the second, and converted to third-packets compatible with the wired-protocol by removing the synchronization-bits. Latency is improved by initiating/starting a packet to the wired controller before a data portion of the packet is received. The number of synchronization bits is selected so the second-packets are aligned and synchronized with wireless-protocol packets.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a control node may receive, from a movable relay node, a capability message indicating a set of operational parameters for the movable relay node. The control node may determine a location for the movable relay node based on the capability message and may transmit, to the movable relay node, a location message indicating the determined location. The movable relay node may change locations or reconfigure one or more relay devices (e.g., reconfigurable intelligent surfaces) of the movable relay node based on the location message. Accordingly, the control node may use the movable relay node to relay messages between the control node and a second node, which may increase the likelihood of successful communications between the control node and the second node.

Abstract: A method of improving user experience for initial IP Multimedia Subsystem (IMS) registration is proposed. When a UE boots up or leaves flight mode, the processor of the UE determines a period Tn of time for IMS PDN initial setup on a single Access-Stratum Network, starting from sending IMS PDN setup request. Upon expiration of Tn, the UE aborts the IMS PDN set up request, and performs IMS PDN set up on another Access-Stratum Network. As a result, it allows the UE to rapidly use IMS service when boots up or leaves flight mode.
