A communication apparatus includes an acquisition unit to acquire, from a base station apparatus being connected, switching information including information used for wireless communication with a movably configured base station apparatus to be a switching destination candidate, a determination unit to determine whether or not to switch a base station apparatus to be a connection destination, and a connection unit to, upon determining by the determination unit to switch the base station apparatus to be the connection destination, execute connection to the base station apparatus to be the switching destination candidate on a basis of the switching information.

A communication device is disclosed including a communication unit configured to receive a message including an SCG configuration, wherein the communication unit transmits a message, which does not include the SCG configuration, to another communication device and causes the another communication device to perform full configuration. In other aspects, another communication device and a communication method are also disclosed.

This disclosure provides systems, methods, apparatuses and computer-readable medium for wireless communication. In some aspects, a user equipment (UE) may receive, from a first base station (BS) associated with a fifth generation New Radio (5G NR) radio access technology (RAT), a command of mobility from the 5G NR RAT to a second RAT. The UE may determine that the command of mobility is for voice fallback. The UE may transmit, to a second BS associated with the second RAT and based at least in part on determining that the command of mobility is for voice fallback, a radio resource control (RRC) connection request communication for attempting to communicatively connect with the second BS for voice fallback.

A base station determines a window of time for arrival of uplink signals, wherein the window of time includes a start based on a first expected time of arrival for a first uplink signal from a first UE and an end based on a second expected time of arrival for a second uplink signal from a second UE. The base station detection detects a false base station, such as a L1 man-in-the-middle false base station, based on an uplink signal being received outside of the determined window of time for the arrival of uplink signals.

Aspects of the disclosure relate to configuring, restricting, and/or setting bandwidth part (BWP) or frequency locations for switching from source to target cells in a Layer 1 (L1)/Layer 2 (L2)-Centric Inter-Cell Mobility communication systems. Switching may be allowed for either same, overlapping, or non-overlapping BWPs within an intra-frequency bandwidth shared by the source and target cells.

A cell site configured to perform group user equipment (UE) handoffs. The cell site comprises an application stored in a non-transitory memory that when executed by a processor of the cell site determines that a first UE is to be handed-off, determines that the first UE is a member of a UE group, wherein the UE group comprises the first UE and at least one other different UE, determines radio resources consumed by the UE group, identifies a second cell site that has sufficient idle radio resources to provide the radio resources consumed by the UE group, and sends a handoff message via the radio transceiver to the second cell site, wherein the handoff message identifies each of the UEs that are members of the UE group, whereby the plurality of UEs that are members of the UE group are handed-off as a group to the second cell site.
