Abstract: Millimeter-wave (mmWave) band communication is a very promising technology for 5G small cells. In practice, such a new system will coexist with legacy or evolved microwave band systems, such as E-UTRAN LTE macro-cell cellular systems, for a long time to come. Considering the typical scenarios where a macro cell offers umbrella coverage for clusters of small cells, several control plane (C-plane) architectural choices of macro-assisted 5G mmWave systems from both UE and network's perspectives are evaluated. Termed macro-assisted mmWave, an effective end-to-end integration of the futuristic mmWave small cells and microwave macro cells shall promise the benefits of both yet avoid individual limitations. The proposed On-demand Reconfiguration C-Place Architecture (ORCA) for Macro-assisted Millimeter Wave (mmWave) small cells is designed to meet 5G expectations of dense deployment of small cells and UEs and beamformed intermittent Gbps links.

Abstract: Various examples pertaining to reflective quality of service (QoS) control in wireless communications are described. A user equipment (UE) receives from a wireless network control signaling that activates support of reflective QoS by the UE. The UE determines whether a predefined condition exists. The UE then indicates to the wireless network a change in a capability of the UE to support the reflective QoS responsive to the determining indicating that the predefined condition exists. When the UE receives from the wireless network control signaling that activates support of reflective QoS by the UE, the UE deletes one or more UE-derived QoS rules among a plurality of active UE-derived QoS rules each with a respective reflective QoS (RQ) timer running.

Abstract: A user equipment (UE) compares a total amount of data available for transmission, including a total amount of packet data convergence protocol (PDCP) data volume and radio link control (RLC) data volume pending for initial transmission in two associated RLC entities comprising a primary RLC entity and a secondary RLC entity, to a threshold. In response to the total amount of data available for transmission being less than the threshold, the UE indicates an amount of the PDCP data volume to a first medium access control (MAC) entity associated with the primary RLC entity as well as indicating zero to a second MAC entity associated with the secondary RLC entity. In response to the total amount of data available for transmission being greater than or equal to the threshold, the UE indicates the amount of the PDCP data to both the first MAC entity and the second MAC entity.

Abstract: Methods for LTE-WLAN interworking control and management are proposed. In one novel aspect, a terminal equipment (TE) can use an AT command to query the WLAN offloadability of a packet data network (PDN) connection. A mobile termination (MT) can store the WLAN offloadability indication in its memory and return the value to TE upon receiving the AT command. In one example, a new field can be added to an existing AT command.

Abstract: A network-based solution of supporting IP multimedia subsystem (IMS) call setup in a next generation system (5GS) is proposed. During an attach or registration area update procedure, a serving base station sends an indication to a UE indicating whether IMS voice over PS session is supported or not. Upon receipt of the indication that IMS VoPS is supported, the UE triggers an IMS registration procedure. However, when an MO/MT call happens, the network determines that the UE may be in conditions where voice service is not supported because the network is not able to provide a successful IMS VoPS over the current serving cell connected to 5G core network. The network then triggers a RAT change or a EPS fallback procedure such that the UE is handover to a target cell that supports IMS VoPS.

Abstract: Described herein are a method and a mobile communication device that support data preprocessing in a mobile communication system, and in particular, a method and a mobile communication device to report buffer status that can indicate an amount of preprocessed data, for example when using 5G NR technology. An amount of preprocessed data is determined and transmitted to a network element by a user equipment (UE) in a buffer status report (BSR).

Abstract: Methods for LTE-WLAN interworking control and management are proposed. In one novel aspect, a mobile termination (MT) can use an AT command to report the change of a RAN rule and/or a RAN condition match. A terminal equipment (TE) can use the AT command to query a list of matches and current RAN measurement values. A RAN rule match means one or more than one of RAN rules satisfy the threshold provided by the network according to TS36.304 description, or change from satisfied to unsatisfied. A RAN condition match means all RAN rules within a RAN condition are all satisfied according to TS36.604 description, or if any of the RAN condition change from satisfied to unsatisfied. If the reporting is enabled by TE, an unsolicited result code (URC) is sent from MT to TE whenever changes in the current RAN rule or RAN condition match occur.

Abstract: Methods and apparatus are provided to reduce service interruption for intra-RAT and inter-RAT handover procedures. The UE performs a NAS signaling procedure via a NAS signaling connection in a mobile communication network. The UE monitors a radio resource status and determines whether a radio bearer has been or is being established for a RRC connection for data transmission. The UE determines whether to release the NAS signaling connection after completing the NAS signaling procedure based on whether the radio bearer has been established. In one embodiment, the UE monitors a radio resource status and determines whether a radio bearer has been established for a RRC connection for data transmission. The UE determines whether to start a timer upon completing the NAS signaling procedure based on whether the radio bearer has been or is being established.

Abstract: A method to manage call continuity in a network environment including a circuit-switched network and an IP multimedia subsystem (IMS) network is provided. A UE monitors one or more ongoing sessions in an IMS network, and the ongoing sessions contain at least one conference call. The UE detects a network-switching event for the UE to switch from the IMS network to a circuit-switched CS network. The UE then determines the one or more ongoing sessions within the IMS network to be released or transferred to the CS network. Finally, the UE performs a session transfer procedure for transferring the determined sessions.
