The disclosure provides a method for beam footprint handover, a method for receiving information, a method for transmitting information, a terminal and a base station. The method for beam footprint handover performed by a terminal comprises the following steps: receiving a first signaling, wherein the first signaling is used for instructing the terminal to hand over from a first beam footprint to a second beam footprint; handing over from the first beam footprint to the second beam footprint in response to the first signaling; wherein a beam footprint is a coverage range of the downlink beamforming signals, the first beam footprint and the second beam footprint belong to a same cell, and downlink signals in the first beam footprint are transmitted with the first beam, while downlink signals in the second beam footprint are transmitted with the second beam.

Apparatus and methods are provided for TA maintenance and acquisition for mobility with inter-cell beam management. In one novel aspect, the source TAG is maintained with the associated TAT running when cell switch is performed to switch from the source cell to a target cell and skips the RA procedure when a valid target TAG exists. In one embodiment, the target TAG is valid when there is the target TAG exists and a TAT of the target TAG is running. The UE performs a RA to the target when the UE determines that there is no TAG associated with the target or when a TAT of the target TAG expires. The source cell and the target cell belong to the same cell group or different cell group. In one embodiment, the UE performs a partial MAC reset and maintaining a TAT associated with the source cell.

Methods and apparatuses for methods and apparatuses for facilitating serving cell changes based on signaling related to beam management procedures in a wireless communications network. A user equipment (UE) comprises a transceiver and a processor operably coupled to the transceiver. The transceiver is configured to receive a transmission configuration indicator (TCI) state identifier (ID) associated with a target serving cell, receive a cell switch command, and transmit, in response to reception of the cell switch command, a channel conveying a positive hybrid automatic repeat request acknowledgement (HARQ-ACK). The processor is configured to perform, based on the cell switch command, a cell switch at a time, wherein the time corresponds to a slot that starts after a cell switch application time from a last symbol of the channel conveying the positive HARQ-ACK.

Provided is a method for performing a random access procedure by a terminal in a wireless communication system. The method comprises the steps of: selecting a first beam having a quality equal to or higher than a preconfigured threshold value; transmitting a random access preamble to a base station via the first beam; adjusting the threshold value when it is determined that the random access procedure has failed; and reselecting a second beam having a quality equal to or higher than the adjusted threshold value.

Methods, systems, and devices for wireless communications are described that provide for user equipment (UE) camping in a virtual cell. A UE may camp in a virtual cell and may be in an idle mode or an inactive mode in the virtual cell. The UE may transition out of the idle or inactive mode and switch from camping in the virtual cell to connecting to a physical cell encompassed by the virtual cell through reselection, redirection, and handover procedures. The virtual cell may include a central unit and multiple distributed units, which may be configured in various physical implementations. Additionally, the virtual cell may be limited to broadcast only or selective unicast signaling.

Methods and systems are provided for dynamically reallocating user devices between two or more radio access technologies based on a current frequency allocation. It is determined that a quantity of user devices using a first radio access technology at a base station is above a threshold. A current frequency allocation is then determined between the first radio access technology and a second radio access technology. Based on the quantity of user devices using the first radio access technology being above the threshold and the current frequency allocation, one or more user devices from the quantity of user devices are reallocated from the first radio access technology to the second radio access technology.

Systems and method are directed towards provisioning multiple cloud cores for new wireless services. An order for the new wireless service for a customer device is received and a customer identifier associated with the order is determined. A first service and a second service are identified for the order based on the customer identifier. The first service is different from the second service. A first cloud core is provisioned for the first service. And a second cloud core is provisioned for the second service. The second cloud core executes separately from the first cloud core.
