Abstract: Provided is a technology related to a terminal apparatus, a base station apparatus, a method, and an integrated circuit capable of reducing complexity of protocol processing, reducing deterioration of phone call quality, and efficiently performing communication. A terminal apparatus for communicating with a base station apparatus includes: a reception unit configured to receive an RRC message from the base station apparatus; and a processing unit configured to configure a packet loss prohibit timer according to a packet loss rate report prohibit timer field included in the RRC message and configured to, based on reception of a report of a packet loss rate from a higher layer and a fact that a packet loss rate report prohibit timer is not running, create a packet loss rate report content, start the packet loss rate report prohibit timer, and perform transmission to the base station apparatus.

Abstract: The present disclosure provides a technology pertaining to a terminal device, a base station device, a method and an integrated circuit which can reduce the complexity of protocol processing and perform efficient communications. The terminal device includes: a receiving unit which receives an RRC connection reconfiguration message from the base station device; and a processing unit, wherein, when information for indicating that full configuration is applied is included in the RRC connection reconfiguration message, on the basis of the terminal device performing an E-UTRA/5GC or NGEN-DC, performs an RLC entity re-establishment, an NR PDCP entity release, an RLC entity release, a logical channel release, and a DRB identifier on a DRB which corresponds to each DRB identifier set by the terminal device release, and performs an SDAP entity notification, which corresponds to the DRB, of a release of the DRB.

Abstract: A mobile node (MN) 100 selects an AP 302 in a subnetwork 300 as the next AP to which it is wirelessly connected, while it is present within a cell 203 corresponding to a subnetwork 200 and wirelessly connected to an AP 202 in the subnetwork 200. The MN 100 transmits data indicating a request for BETH and the next AP to which it is wirelessly connected to an AR 201 via L3 level communication, while the MN 100 is present within the cell 203. The AR 201 implements establishment of a BET between an AR 301 in the subnetwork 300 and itself. As a result, the MN 100 can still use a care of address adapted to the subnetwork 200 even after it is wirelessly connected to the subnetwork 300.

Abstract: A method, and associated apparatus, facilitates handover of communications with a mobile Bluetooth device operable to communicate packet data with other Bluetooth devices. Handover of communications is effectuated between fixed-infrastructure access points or other mobile Bluetooth devices formed in a scatternet. The device to which communications are to be handed-over becomes a slave to the Bluetooth device with which communications are ongoing, thereby to permit time synchronization thereto.

Abstract: Apparatus, and an associated method, for utilizing a Bluetooth-compatible access point and mobile stations of a WLAN (Wireless Local Area Network) system. A manner is provided by which to increase the number of mobile stations capable of communicating with an access point at any particular time during operation of the WLAN system. Limitations associated with a maximum of communication devices capable of forming a single piconet are obviated as additional piconets are defined, as required, to accommodate increased numbers of mobile stations to communicate with the access point of the WLAN system.
