A cloud-based system for maintaining a distributed cloud spectrum access system (SAS) is disclosed. The system may include one or more processors; and a memory storing instructions that cause the one or more processors to perform the a method including: syncing one or more edge databases at a frontend-SAS with corresponding cloud databases at a backend-SAS; monitoring a connection between the frontend-SAS and the backend-SAS; determining the connection between the frontend-SAS and the backend-SAS has been severed; continuing to operate within an interference headroom; attempting one or more robustness mechanisms to ensure impact to the frontend-SAS is minimized and to reestablish the connection between the frontend-SAS and the backend-SAS; and upon determining the connection is reestablished, reconciling the one or more edge databases at the frontend-SAS with the corresponding cloud databases at the backend-SAS.

Aspects of the present disclosure provide techniques switching a communication link for wireless systems with multiple parents, such as an Integrated Access and Backhaul (IAB) network or other type of network. In some cases, a node determines a partition of a number of desired guard symbols between a first parent node and a second parent node; sends, to the first parent node and to the second parent node, at least one indication of a partitioned number of the desired guard symbols for switching between the first parent node and the second parent node; receives at least one indication of a number of provided guard symbols from the first and second parent nodes; and switches a communication link from the first parent node to the second parent node in accordance with the at least one indication of provided guard symbols by the first parent node and the second parent node.

A user equipment (UE) may establish a wireless connection with a WiFi network, and may perform a measurement associated with a fifth generation (5G) ultra-wideband radio access network. The UE may determine whether the measurement satisfies a signal strength threshold, and may selectively perform a first action or a second action based on whether the measurement satisfies the signal strength threshold. The first action may include providing an indication of an availability of the 5G ultra-wideband radio access network, for display, when the measurement satisfies the signal strength threshold. The second action may include maintaining the wireless connection when the measurement fails to satisfy the signal strength threshold.

A method, performed by a communication device operating in dual connectivity with a master cell group, MCG, and a secondary cell group, SCG, of a wireless communication network includes receiving a message from a network node of the wireless communication network, the message including an instruction to perform a mobility procedure concerning at least one of the MCG or the SCG, determining an SCG state for power saving for the communication device, executing the mobility procedure according to the instruction and the SCG state, and applying the determined SCG state following execution of the mobility procedure.

An apparatus and method for providing handover support information in a mobile communication system are provided. A method for an Base Station (BS) to provide information necessary for measurement report trigger performance to a Mobile Station (MS) after the MS determines neighboring BSs in a mobile communication system includes, in a case where the MS is an active mode MS, providing a Time To Trigger (TTT) independently by a specific neighboring BS to the active mode MS and, in a case where the MS is an idle mode MS, providing a reselection time period (Treselection) independently by the specific neighboring BS to the idle mode MS.

The present invention relates to a method and a device for transmitting a signal of mobility, for transmission or reception of a first radio access technology (RAT)-based signal in a wireless communication system. Specifically, the method comprises the steps of: generating a first RAT-based signal including a message relating to generation of an event; duplicating the message into a second RAT-based signal when the event is associated with a safety service; and transmitting the second RAT-based signal through a resource area associated with the first RAT when the event is associated with the safety service.

A radio node in a network (such as a small cell) that receives predefined handover parameters is described. During operation, the radio node may receive, from a computer (such as a controller), information specifying the predefined handover parameters, where the predefined handover parameters correspond to a density of radio nodes in the network. For example, the radio node may provide, to the computer, information specifying the density of radio nodes in the network. Moreover, the radio node may receive, from the electronic device, information specifying a communication-performance metric associated with the radio node. Next, the radio node may provide, to the electronic device, a recommendation for a handover from the radio node to another radio node in the network based at least in part on the predefined handover parameters, the communication-performance metric and a second communication-performance metric associated with the other radio node.
