    Abstract: Apparatus and methods are provided for initial access in the multi-beam operation. In one novel aspect, the UE receives multiple response messages and selects one message as the response message. In one embodiment, the UE selects a subset of a configured UL resources, transmits a first message, wherein the first message is transmitted one or more times on each of the selected set of UL resources, receives one or more first-message-response messages from the BS, and selects one response message, wherein the selected response message indicates a corresponding BS RX resource, which is used by the UE for subsequent communication with the BS. In one embodiment, the selection of UL resources is at least based on transmitting spatial characteristics of the BS, the UE or both, which indicates whether the BS/UE is reciprocal, partial reciprocal or non-reciprocal.

    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: 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.
