    Abstract: Inter-cell coordination and beam-aware scanning with end-to-end UE-BS signaling enhancements for robust HO trigger in a beamforming mmWave network is proposed. From the network and the base station perspective, inter-BS control beam coordination is performed, coupled with neighbor-cell information advertisement to facilitate UE-side beam-aware scanning. Inter-BS CB coordination enables a variety of network planning, pre-determined or random, enhanced with UE-reports and dynamic re-coordination to minimize inter-cell interference. From UE perspective, by utilizing the advertised CB information, UE can learn serving cell and neighbor cell CB pattern for beam-aware scanning. Beam-aware scanning enables power saving fast scanning at the UE with beam-aware HO measurement of neighboring and target cells, which reduces HO latency and avoids unnecessary HO.

    Abstract translation: 提出了在波束成形mmWave网络中用于鲁棒HO触发的端到端UE-BS信令增强的小区间协调和波束感知扫描。 从网络和基站的角度来看，执行BS间控制波束协调，并与邻居小区信息通告相结合，便于UE侧波束感知扫描。 BS间协调使得能够通过UE报告和动态重新协调来增强预定义或随机的各种网络规划，以最小化小区间干扰。 从UE的角度来看，通过利用所通告的CB信息，UE可以学习用于波束感知扫描的服务小区和相邻小区CB模式。 光束感知扫描使得能够在UE处能够快速扫描相邻和目标小区的波束感知HO测量，这降低了HO等待时间并避免了不必要的HO。

    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. The multicast MBMS bearer is associated with a Temporary Mobile Group Identifier (TMGI), and wherein the TMGI is associated with the communication group ID. The UE later enters RRC_IDLE mode and releases a radio bearer of the unicast EPS bearer while keep monitoring the multicast MBMS bearer for the DL multicast traffic.

    Abstract: A method of beam misalignment detection for wireless communication system with beamforming is proposed. To identify a misaligned beam, a relative beam quality degradation is applied by comparing a dedicated beam quality with a reference beam quality. The reference beam favors similar transmission path as the dedicated beam, and has better mobility robustness. In one embodiment, the reference beam is an associated control beam of the dedicated beam. To detect beam misalignment, a first dedicated beam SINR is compared with a second associated control beam SINR.

    Abstract: An effective SCELL activation procedure is proposed to reduce the SCELL activation time. For carrier aggregation, a secondary cell (SCELL) needs to be configured and then activated before a UE can perform normal operation. In a first embodiment, the UE performs measurements on a list of candidate SCELLs before SCELL configuration. In a second embodiment, the UE performs measurements on a configured SCELL with high priority after the SCELL is configured. In a third embodiment, the UE performs deactivated-state SCELL measurements with adaptive SCELL measurement interval based on a configured measurement cycle and a state machine. Small SCELL activation time allows energy saving and network scheduling gain.

    Abstract translation: 提出了一种有效的SCELL激活程序来减少SCELL激活时间。 对于载波聚合，需要配置二次小区（SCELL），然后在UE可以执行正常操作之前激活。 在第一实施例中，UE在SCELL配置之前对候选SCELL的列表进行测量。 在第二实施例中，在配置SCELL之后，UE在配置好的高优先级的SCELL上执行测量。 在第三实施例中，UE基于配置的测量周期和状态机，以自适应SCELL测量间隔执行去激活状态SCELL测量。 小的SCELL激活时间可以节省能源和网络调度增益。

    Abstract: Examples pertaining to measurement resource and report configuration for a communication apparatus supporting device collaboration in mobile communications are described. A user equipment (UE) receives a first report configuration associated with at least a first measurement resource allocated in a first frequency band from a network node. The UE determines information regarding a second measurement resource allocated in a second frequency band which is different from the first frequency band. The UE receives a first radio frequency (RF) signal carrying one or more reference signals on the first measurement resource and receives a second RF signal carrying identical one or more reference signals on the second measurement resource.
