To prevent a client device from being stranded, a steering controller of an access point device can provide an improved network environment or performance by steering a target client device to a basic service set (BSS) of a network device that is different from the current BSS of the target client device based on a first or a poor link quality threshold where non-associated client (NAC) link quality parameters for NAC network devices within the network environment, such as a mesh network, is not available. The steering controller can select or identify a candidate BSS and then send a steering query to the target client device. The steering controller can receive a response from the target client device that indicates whether the steering to the candidate BSS was successful or accepted by the targeted client device.

Embodiments herein relate to for example a method performed by a radio network node for handling a communication of a user equipment, UE, in a wireless communication network. The radio network node transmits a handover command for handing over the UE, from a source cell to a target cell, wherein a security parameter for encrypting data communicated between the radio network node and the UE is retained during the handover. Furthermore, the radio network node maintains a sequence number status for reception and/or transmission of a signalling radio bearer of the UE during the handover from the source cell to the target cell, and/or at a fallback from the target cell to the source cell, when the UE triggers the fallback to the source cell.

A method and system for performing handover in a third generation (3G) long term evolution (LTE) system are disclosed. A source evolved Node-B (eNode-B) makes a handover decision based on measurements and sends a handover request to a target eNode-B. The target eNode-B sends a handover response to the source eNode-B indicating that a handover should commence. The source eNode-B then sends a handover command to a wireless transmit/receive unit (WTRU). The handover command includes at least one of reconfiguration information, information regarding timing adjustment, relative timing difference between the source eNode-B and the target eNode-B, information regarding an initial scheduling procedure at the target eNode-B, and measurement information for the target eNode-B. The WTRU then accesses the target eNode-B and exchanges layer 1/2 signaling to perform downlink synchronization, timing adjustment, and uplink and downlink resource assignment based on information included in the handover command.

A method for operating a relay node during a handoff from a first controller to a second controller includes receiving a first instruction from the first controller to discontinue using a first set of wireless backhaul link resources allocated to the relay node by the first controller and to temporarily use a second set of wireless backhaul link resources dedicated by the second controller. The method also includes receiving a second instruction from the second controller to discontinue using the second set of wireless backhaul link resources and to begin using a third set of wireless backhaul link resources allocated to the relay node by the second controller.

Various embodiments are generally directed to improved channel quality information feedback techniques. In one embodiment, for example, an evolved node B (eNB) may comprise a processor circuit, a communication component for execution by the processor circuit to receive a channel quality index for a physical downlink shared channel (PDSCH), the channel quality index associated with a defined reference resource, and a selection component for execution by the processor circuit to select a modulation and coding scheme (MCS) for transmission over the PDSCH of user equipment (UE) data in one or more resource blocks, the selection component to compensate for a difference between a cell-specific reference signal (CRS) overhead of the defined reference resource and a CRS overhead of the one or more resource blocks when selecting the MCS. Other embodiments are described and claimed.

A user equipment (UE) of re-organizing a timing advance group (TAG) is provided. The UE includes: a receiving unit for receiving, from a serving base station, secondary serving cell (SCell) configuration information which includes a first field and a second field, the first field including an ScellIndex of an SCell to indicate a removal of the SCell, the second field including at least one of the ScellIndex to indicate an addition of the SCell and a TAG ID indicating a TAG of the SCell, and a radio resource control (RRC) processing unit for performing the addition of the SCell after performing the removal of the SCell from one or more SCells configured in the UE, and for reorganizing the TAG by including the SCell in the TAG.

A network node, a wireless device and methods for use in a Random Access, RA, procedure with wireless devices in a cell of the network node. The method of the network node comprises receiving, from at least two wireless devices, a RA message having an RA preamble; transmitting an RA Response, RAR, to the wireless devices, the RAR having a TC-RNTI and an RA preamble identifier identifying the received RA preamble; and receiving, from each of wireless the devices, a connection request message having a respective S-TMSI. For a wireless device previously connected to the network node in the same cell, a connection setup message addressed to a C-RNTI previously assigned to the wireless device is transmitted. For a wireless device not previously connected to the network node in the same cell, a connection setup message addressed to the TC-RNTI is transmitted.

The present disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure provides a method of de-activating a local internet protocol access (LIPA) bearer supporting local breakout in a dual-connectivity architecture. When a master eNodeB (MeNB) determines to change a secondary eNodeB (SeNB) serving a user equipment (UE) or hand the UE over from the MeNB to an eNB, the MeNB may trigger a LIPA bearer de-activation process, and then trigger the process of change the SeNB serving the UE or hand the UE over from the MeNB to the eNB. Various examples also provide another method and an apparatus for de-activating a LIPA bearer, for bearer switch, for establishing a LIPA bearer. The methods and apparatus can establish, switch and correctly release local breakout bearer in a dual-connectivity architecture, so as to reduce the load of a core network of an operator.

A User Equipment (UE) registers with a Long Term Evolution (LTE) network. The UE registers with an Internet Multimedia Subsystem (IMS) over the LTE network. The UE registers with a Wireless Fidelity (WIF) network. The UE receives a status request from the LTE network responsive to a Session Initiation Protocol (SIP) invite for the UE received at the IMS. The UE transfers a status response to the LTE network that indicates the WIFI network responsive to the status request. The UE receives the SIP invite from the IMS over the WIFI network. The UE exchanges user data for the media session over the WIFI network.

An apparatus of a base station (BS) of a radio access network (RAN) comprises memory and processing circuitry. The processing circuitry includes a central unit (CU) portion and a distributed unit (DUI) portion that implement a BS multi-layer protocol stack divided between the CU portion and the DU portion. The processing circuitry initiates a handover to change a serving cell of user equipment (UE). The handover includes a change in a portion of logical layers of the BS multi-layer protocol stack, and the processing circuitry encodes an information element for transmission to the UE indicating logical layers of a UE multi-layer protocol stack implemented in the UE to be reset by the UE in association with the handover.
