    摘要： Systems and methods described herein are provided for beamforming and uplink control and data transmission techniques. Such techniques enable a UE to maintain at least one beam process for operation with multiple beams and/or points. A beam process may be indicated for transmission or reception over a downlink or uplink physical channel. Power, timing, and channel state information may be specific to a beam process. A beam process may be established as part of a random access procedure in which resources may be provisioned in random access response messages. Techniques are provided to handle beam process failures, to use beam processes for mobility, and to select beams using open-loop and closed-loop selection procedures.

    摘要： A system and methods for performing phased reconfiguration in a wireless communications system are disclosed. A wireless transmit/receive unit (WTRU) may perform a phased reconfiguration from a source cell to a target cell. The WTRU may be connected to the source cell and may execute a first set of functions towards the source cell. The WTRU may monitor for a first set of preconfigured trigger conditions and a second set of preconfigured trigger conditions. The WTRU may commence a second set of functions towards the target cell based on detection of at least one of the first set of preconfigured trigger conditions while continuing to execute the first set of functions towards the source cell. The WTRU may cease to perform at least a subset of the first set of functions towards the source cell based on detection of at least one of the second set of preconfigured trigger conditions.

    摘要： Systems and method are specified to improve the reception of UL transmission, for example in power or coverage limited situations. A WTRU may modify procedures to increase the available signal energy for reception at an eNB and/or to make more efficient use of the available signal energy at the receiver for processing UL transmissions. Example methods for increasing UL link coverage may include modifying HARQ timing (e.g., shorter HARQ), using longer TTIs, use of dedicated PUSCH allocations, use of new PUSCH modulations, enhanced reference signal design, UL macro diversity reception for PUSCH, utilizing protocol reduction techniques, ensuring in-order packet delivery, and/or utilizing a configuration for coverage limited/power limited modes of operation. The proposed methods may be applied individually or in any combination.

    摘要： Systems and methods are contemplated for reconfiguration of one or more MAC instances while the WTRU is operating using dual- or multi-MAC instance connectivity. For example, upon reception of RRC reconfiguration information that modifies one or more secondary MAC instances, the WTRU may transmit a reconfiguration complete message to a Macro eNB (MeNB) and may synchronize to small-cell or secondary eNB (SeNB), for example if triggered by one or more of an RRC flag, a physical downlink control channel (PDCCH) order (MeNB/SeNB), MAC activation information, etc. For example, the WTRU may synchronize to the SeNB for specific type(s) of RRC reconfigurations, but not other type(s) of RRC reconfigurations. Although examples may be described in terms of dual connectivity, the WTRU may establish connectivity and perform mobility procedures with more than two radio access network (RAN) nodes (e.g., eNBs), and the embodiments described may be equally applicable to those scenarios.
