Abstract: In a heterogeneous network, enhanced handover and reestablishment procedures are proposed within a local area network. The enhanced procedures are more efficient, e.g., with less signaling and less data interruption than the legacy mobility mechanism. In a local area network, a UE is served by an anchor eNB in macro cell layer and one or more drift eNBs in small cell layer. When the UE moves within the local area network, the UE anchor does not need to change. For cell change within the same anchor, the enhanced procedures reduces signaling overhead and data interruption time.

Abstract: Methods to manage multiple component carriers (CCs) efficiently in a mobile network with carrier aggregation (CA) enabled are proposed. For CC activation/deactivation, a single LCID value is used to represent both activation and deactivation command. A single command with multiple instructions is provided to activate and/or deactivate multiple CCs. In addition, unnecessary re-activation or re-inactivation of a CC is prevented, and explicit feedback for activation/deactivation is considered. For scheduling mechanism, a novel buffer status reporting (BSR) procedure is provided, where only one BSR is calculated after preparing all the transport blocks (TB) within one transmission time interval (TTI). Novel power headroom reporting (PHR) format and trigger are also provided. For DL-UL linking, various linking types are created based on whether there is carrier indicator field (CIF) in DL grant or UL grant. The various linking types are used in different applications to improve scheduling flexibility and load balancing.

Abstract: A method and apparatus for transmitter assisted Quality of Service (QoS) measurement. Time information is generated by the transmitter and transmitted along with a data transmission. A receiving device determines a QoS measurement based upon the time information and the received data. The time information indicates when the data was made available for transmission, which data transmission blocks belong to a single data transmission, and when a transmitter buffer was emptied. The QOS measurements are performance measurement such as, latency measurements and throughput measurements. The time information indicates a time reference relative to the timing of a wireless interface. The time reference is a System Frame Number (SFN), a Connection Frame Number (CFN), a relative count of frame numbers, a count of sub-frames, or a count of Time Transmission Intervals (TTIs). An aggregated QOS measurement is generated based upon the QOS measurement.

Abstract: A method for scheduling request triggering based on traffic condition is provided. The method supports detecting a traffic condition, determining a modified scheduling request (SR) trigger based on the traffic condition and transmitting a scheduling request to a base station based on the modified SR trigger. In one embodiment, the modified SR trigger is a data buffer or a data generation rate exceeding a threshold. In one embodiment, the threshold is related to a prioritized Bit Rate (PBR) or a bucket Size Duration (BSD) or both. In another embodiment, the threshold is configured by the base station based on a size of the smallest grant under the traffic condition. In one embodiment, the threshold is updated when DRX state changes. In another embodiment, during DRX sleep state, the SR period is longer or SR is stopped.

Abstract: Apparatus and methods are provided for efficient bandwidth adaptation for wideband carrier. In one novel aspect, the UE starts a BWP timer upon detecting one or more BWP timer starting triggering events, resets the BWP timer upon detecting BWP resetting triggering events, and switches to the default BWP upon expiration of the BWP timer. The BWP timer starting triggering events comprises decoding a command to switch away from the default BWP, the detection of end of DL data transmission in DRX mode. In another novel aspect, the UE only decodes the DCI indication for active BWP switching in the first three OFDM symbols of a subframe or a slot. In yet another novel aspect, when the SPS is configured for the serving cell for a UE with multiple BWPs, the SPS is configured for all the BWPs accordingly.

Abstract: Methods and apparatus are provided for the RRC message segmentation. In one novel aspect, the UE obtains the size Z of the RRC message and the size limit L of the underlying transmission at layer S of the UE protocol stack, wherein the layer S either the RRC layer, the PDCP layer, or a sublayer between an RRC layer and a PDCP layer. The UE triggers RRC message segmentation upon detecting Z is greater than L. In another embodiment, the layer R of the protocol stack of the UE receives, in order, a sequence of chunks of an RRC message, reassembles of the RRC message, wherein the layer R is selected from a same layer as the layer S and a layer higher than the layer S. In one novel aspect, the size limitation L is either predefined or obtained through network notification or UE inquiry.

Abstract: Method and user equipment (UE) are provided for early evaluation termination. In particular, a UE can receive a downlink (DL) reference signal (RS) from a network. The UE can measure the DL RS to derive a measurement. Then, the UE can adjust a time value or a count value based on the measurement.

The count value is configured by the network for triggering beam failure recovery or random access procedure.
