Abstract: A method of supporting group communication over LTE MBMS is provided. A UE first establishes a unicast Evolved Packet Service (EPS) bearer in an LTE network for group communication. The UE belongs to a communication group having a communication group ID. The UE receives access information from the network for monitoring downlink (DL) multicast traffic of the DL group communication based on a multicast decision. The UE is then ready for monitoring a multicast Multimedia Broadcast Multicast Service (MBMS) bearer for receiving the DL multicast traffic. In one embodiment, The UE requests to switch the DL multicast traffic from the multicast MBMS bearer to the unicast EPS bearer upon detecting that the UE is approaching an MBMS coverage boundary. In another embodiment, the UE transmits an indication of preferred target cells to the network before performing a handover and thereby maintaining multicast service continuity of the group communication.
Abstract translation: 提供了一种通过LTE MBMS支持群组通信的方法。 UE首先在用于组通信的LTE网络中建立单播演进分组业务（EPS）承载。 UE属于具有通信组ID的通信组。 UE从网络接收基于多播决定的DL组通信的下行链路（DL）组播流量的接入信息。 然后，UE准备监视用于接收DL多播业务的组播多媒体广播多播服务（MBMS）承载。 在一个实施例中，当UE正在接近MBMS覆盖边界时，UE请求将DL组播业务从组播MBMS承载切换到单播EPS承载。 在另一个实施例中，UE在执行切换之前向网络发送优选目标小区的指示，从而保持组通信的多播服务连续性。

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 user plane (U-plane) architectural choices of macro-assisted 5G mmWave systems from both UE and network's perspectives are evaluated. The proposed On-demand Reconfiguration U-Plane Architecture (ORUA) 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: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives a radio bearer configuration. The UE also configures, based on the received radio bearer configuration, a radio bearer including a first logical channel on a first carrier and a second logical channel on a second carrier. The UE further determines whether to activate the radio bearer to perform duplication. In response to a determination to activate the radio bearer to perform duplication, the UE communicates a first packet on the first logical channel and communicates a duplicated first packet on the second logical channel.

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: AT commands are used for controlling Mobile Termination (MT) functions and GSM/UMTS network services from a Terminal Equipment (TE) through Terminal Adaptor (TA). 3GPP introduces multiple backoff timers and barring to solve network congestion problem. However, a TE does not know the timer value and the barring status. In accordance with one novel aspect, a new AT command interface that can respond timer value and barring status to the TE is proposed. It reduces wasteful retries and saves power consumption of the TE. Through the new AT command interface, the TE can query backoff timer status. Via unsolicited result code (URC), the MT can detect backoff timer status change and report updated backoff timer status to the TE.

Abstract: A method for reducing power consumption when a communications apparatus establishes voice communications with another communications apparatus includes estimating a voice quality perceived by a user of the another communications apparatus; determining whether the estimated voice quality is higher than a predetermined threshold; and adjusting at least one parameter utilized for processing a plurality of voice packets to be transmitted to the another communications apparatus according to the estimated voice quality to reduce the power consumption when the estimated voice quality is higher than the predetermined threshold.

Abstract: A method of control Maximum Transmission Unit (MTU) reporting and discovery using AT commands is proposed. In communications networks, the MTU of a communication protocol of a layer is the size (in bytes or octets) of the largest protocol data unit that the layer can pass onwards. In an IP network, IP packets may be fragmented if the supported MTU size is smaller than the packet length. In accordance with one novel aspect, the packet data protocol (PDP) context of a packet data network (PDN) connection comprises MTU information. By introducing MTU information to the PDP contexts, TE can use AT commands to query MTU parameters from the network and thereby avoid fragmentation. TE can also use AT command to set MTU parameters and thereby control MTU discovery.

Abstract: Methods for enhanced UE data transmission for power consumption optimization are disclosed. A UE detects UE conditions and determines a UE traffic characteristic. The UE performs power consumption optimization based on the traffic characteristic. In one novel aspect, based on the UE condition, the UE determines that the traffic characteristic is low priority traffic or mobile originated only traffic. In one embodiment, the UE aligns prescheduled low priority data transmission with mobility management messages, or group multiple low priority prescheduled data transmission together. In another embodiment, the UE reduces NAS retry process upon detecting application triggered low priority traffic. In another embodiment, the UE turns off RF module until next data transmission for MO only traffic. In another novel aspect, the UE detects and sends UE conditions to the network. The network determines a UE traffic characteristic and performs power consumption optimization accordingly.

Abstract: Aspects of the disclosure provide a processing circuit in an electronic apparatus and a method to switch the electronic apparatus during an inter-system handover (HO) process from a source network system to a target network system. The processing circuit can include an inter-system HO signal processing module and a mapping module. The inter-system HO signal processing module can be configured to obtain a mapping relationship between a set of source bearers associated with the source network system and a first set of target bearers associated with the target network system based on quality of service (QoS) characteristics associated with the set of source bearers and the first set of target bearers. The mapping module can be configured to obtain a second set of target bearers based on resources allocated to the first set of target bearers by the target network system and to obtain a third set of target bearers that is based on the first and second set of target bearers.
