    Abstract: A method of power headroom reporting in adaptive TDD systems is proposed. A UE obtains configuration information from a base station in an adaptive TDD system. Each radio frame comprises a plurality of subframes, which are configured into two or more subframe sets. The UE determines a power headroom reporting (PHR) triggering condition. The UE performs PHR for at least one of the configured two or more subframe sets upon satisfying the triggering condition. In one embodiment, the UE sends PH values for all subframe sets in the same PH reporting subframe. In another embodiment, the UE sends PH values for different subframe sets in different PHR reporting subframes.

    Abstract: A method of network-based positioning using sounding reference signal (SRS) is proposed. An eNodeB configures a number of parameters of a periodic SRS transmission for a user equipment (UE). The eNodeB then transmits SRS configuration data for SRS measurements performed by a location measurement unit (LMU). The SRS configuration data includes cell-specific SRS bandwidth configuration and UE-specific SRS bandwidth configuration. The SRS configuration data may further include a number of antenna ports for SRS transmission, SRS frequency hopping bandwidth configuration, information on whether SRS sequence-group hopping is enabled, and ΔSS when SRS sequence hopping is enabled. Upon receiving the SRS configuration data, the LMU is able to perform timing measurements over the received SRS signals from the UE. In one embodiment, the LMU detects SRS dropping to avoid performance degradation of the network-based positioning.

    Abstract: A new design for physical downlink control channel (PDCCH) is proposed for the next generation 5G new radio systems. A UE receives the configuration of a default control resource set (CORESET) in MIB/SIB from its serving base station. The default CORESET contains both common search space and UE-specific search space for candidate PDCCH transmission. A PDCCH in a default CORESET is mapped to physical resource in a distributed or localized manner. Specifically, various REG-to-CCE mapping rules are proposed to improve frequency diversity gain, or frequency selectivity gain, or to reduce latency of PDCCH processing. Further, to facilitate analog beamforming in mmWave systems, the default CORESET is transmitted in a synchronization signal (SS) block associated with a corresponding analog beam direction.

    Abstract: Apparatus and methods are provided for narrow band power saving framework. In one novel aspect, the UE configured with multiple BWPs is configured with a plurality of UE states each associated with one or more configured BWP, and transitions to or from a power-saving state upon detecting one or more transitioning conditions. In one embodiment, the UE transitions to and from the power-saving state upon detecting a switching signal. In another novel aspect, the UE with multiple BWPs is further configured with a leader BWP set for a leader cell, and one or more sets of follower BWP sets for corresponding follower cells of the UE, bundles each leader cell UE state with corresponding follower UE state for each follower cell, and transitions from a corresponding follower cell power saving state automatically for the one or more follower cells upon the leader cell UE state transition.
