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.

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Accordingly, the embodiments herein provide a method for Management data analytic service (MDAS) server (100) assisted handover optimization in a wireless network (1000). The method includes periodically collecting data from a plurality of target gNBs in the wireless network (1000), and generating an analytical report for each target gNB (300) of the plurality of target gNBs based on the collected data. Further, the method includes receiving a request for the analytical report of the at least one target gNB (300) for handover from a source gNB (200), sending the analytical report to the source gNB (200). Further, the includes performing at least one corrective action suggested by the analytical report to optimize at least one target gNB (300) for handover.

Methods, systems, and storage media are provided for exiting conditional handovers and for estimating a user equipment mobility state. Other embodiments may be described and/or claimed.

Certain aspects of the present disclosure are directed to a method for wireless communication. The method generally includes receiving at least one first packet of a sequence of packets from a source cell, the at least one first packet being dependent on at least one second packet of the sequence of packets for decoding, performing a handover from the source cell to a target cell, determining that the at least one second packet of the sequence of packets was not received from the source cell, generating a message requesting a retransmission from the target cell for the at least one first packet and the at least one second packet based on the determination, and transmitting the message to the target cell.

Provided are a cell reselection method and apparatus, an information transmission method and apparatus, a communication device, and a storage medium. The cell reselection method is applied to a terminal, and comprises: receiving first priority information of a frequency point and a network slice combination supported by the frequency point; and performing cell reselection according to the first priority information.

The present disclosure relates to a base station apparatus and a method of operating a base station apparatus capable of improving accuracy of beam steering (steerability) in performing beamforming using an antenna based on multiple input multiple output (MIMO).

A method is provided for transmitting Acknowledgement/Negative Acknowledgement (ACK/NACK) information in a wireless communication system. A User Equipment (UE) configures a Physical Uplink Control Channel (PUCCH) format 3 for transmission of the ACK/NACK information. The UE transmits the ACK/NACK information for downlink transmission in a downlink subframe set including M downlink subframes in one uplink subframe, wherein M>1. A plurality of serving cells are configured for the UE and include one Primary Cell (PCell) and at least one Secondary Cell (SCell). The UE transmits the ACK/NACK information using a PUCCH format 1b when a first condition is met that comprises a condition in case where the ACK/NACK information corresponds to one Physical Downlink Shared Channel (PDSCH) without a corresponding Physical Downlink Control Channel (PDCCH) received only on the PCell in the downlink subframe set and the ACK/NACK information corresponds to an additional PDSCH indicated by detection of one corresponding PDCCH.

Aspects of the present disclosure provide techniques for inter-donor topology discovery in an Integrated Access and Backhaul (IAB) network during migration of an IAB-node. A method that may be performed by a first IAB-donor includes establishing a first signaling connection with an IAB-node, receiving an indication that the IAB-node has a second signaling connection with a second IAB-donor, and in response to receiving the indication: transferring, to the second IAB-donor, information related to the IAB-node, re-establishing traffic between the first IAB-donor and the IAB-node via a topology of the second IAB-donor, or any combination thereof.

A terminal device includes: transmission circuitry that transmits a connection request to a first access point in order to connect, by a wireless link, to one of the first access point or a second access point each having a superframe in an initial state in which a control channel period is longer than a data channel period; and reception circuitry that receives, as a connection response, information indicating the second access point as information on a connection destination access point from the first access point after the connection request is transmitted.

Presented herein are techniques to support handovers in hybrid cell configuration environments. In one example, a method may include determining that a user equipment (UE) is connected to a first shared cell or a first unique cell of a radio access network; and causing a handover for the UE to a second shared cell or a second unique cell of the radio access network based on whether the UE is connected to the first shared cell or the first unique cell, wherein the handover is performed between one of the first shared cell and the second shared cell or the first unique cell and the second unique cell.
