Abstract: Techniques to achieve near zero millisecond mobility of wireless terminals are described. In one example method, a wireless terminal receives a radio resource control message from a source node. The message indicates the use of a simultaneous connectivity mobility of the wireless terminal during a mobility procedure from the source node to a target node. The wireless terminal performs the mobility procedure based on the control message.

Abstract: Methods and systems for handling UE associated information in non-terrestrial networks are disclosed. In one embodiment, a method performed by a satellite head station, includes: translating a first uplink (UL) tunnel address associated with a core network to a second UL tunnel address associated with the satellite head station, wherein the first and second UL tunnel addresses are each associated with a packet data unit (PDU) session established between the core network and a user equipment device (UE); transmitting the second UL tunnel address to a first satellite base station; and receiving UL data associated with the PDU session from the first satellite base station, wherein a UL tunnel address destination associated with the received UL data is set as the second UL tunnel address.

Abstract: A wireless terminal receives a network identifier in a message received on a broadcast channel. The wireless terminal determines that a mobile network code in the network identifier corresponds to a non-terrestrial network. The wireless terminal updates a tracking area list of the wireless terminal by adding or deleting a tracking area identifier corresponding to the non-terrestrial network to the tracking area list.

Abstract: A wireless terminal determines a tracking area code (TAC) from a geographic position of the wireless terminal. From the TAC, the wireless terminal determines the tracking area identity based on an indication from the network-side regarding whether or not geographic position based tracking area identity determination is to be used or not. In some implementations, the network-side is a satellite cell that is configured to provide wireless connectivity to the wireless terminal.

Abstract: Provided are a method and device for requesting system information, a storage medium and a terminal. The method includes that: a terminal performs a cell reselection in the case where the terminal initiates a system information request procedure but has not successfully completed the system information request procedure, the terminal resets an MAC layer or a relevant parameter of an RACH procedure, and the terminal acquires required SI according to an RRC configuration of a reselected cell. When the terminal initiates the system information request procedure, the terminal may immediately reset the MAC layer or the relevant parameter of the RACH procedure after triggering the cell reselection, so as to terminate the current system information request procedure, and acquire the required SI again in the reselected cell.

Abstract: Techniques are described to adjust transmission rates. For example, in a dual-connectivity system, a first communication node can be in communication with a first network node and a second network node. The first communication node may receive from a first network node a first message that includes a recommended bit rate for an ongoing communication between the first communication node and a second communication node. In some embodiments, the first communication node can, in response to receiving the first message, send an acknowledgment or a non-acknowledgment indicator to the first network node indicating that the first communication node accepts or rejects the recommended bit rate.
