Abstract: Aspects of the disclosure provide a method of data transmission that includes determining a transmission time interval for transmission of a transport block and setting a segmentation threshold for the transport block to a first threshold or a second threshold that is less than the first threshold based on the determined transmission time interval. The method includes converting the transport block into one or more outgoing code blocks that each has a size not greater than the determined segmentation threshold and encoding the one or more outgoing code blocks for transmission when communication device is configured to transmit the transport block. The method also includes receiving one or more incoming code blocks that each has a size not greater than the determined segmentation threshold and reconstructing the transport block from the one or more incoming code blocks when communication device is configured to receive the transport block.

Abstract: Apparatus and methods are provided for RRM measurement in the NR network. In one novel aspect, the RRM measurement is configured with one measurement gap for SS block and CSI-RS. In one embodiment, an extended MGL (eMGL) is configured such that the SS block and CSI-RS is measurement within one measurement gap. In another embodiment, the shorter MGL (sMGL) that is shorter than the standard MGL is configured. In another novel aspect, the CSI-RS is allocated adjacent to the SS blocks such that one measurement gap is configured for both the SS block and CSI-RS measurement. In another novel aspect, the CSI-RS measurement is conditionally configured. In yet another novel aspect, the UE decodes the time index of the SS block conditionally.

Abstract: A method of managing bandwidth resources provided by multiple network interfaces is proposed. When one or more network interfaces provide network bandwidth resources, a bandwidth manager manages all available bandwidth resources based on a list of decision criteria. The list of decision criteria includes energy efficiency, network throughput, channel condition, device mobility, and user preference. An application traffic flow distributor dynamically adjusts the amount of traffic flows on different network interfaces according to the joint decision based on the decision criteria. A network interface manager dynamically enables or disables each network interface according to the joint decision based on the decision criteria. Furthermore, a device movement analyzer analyzes and predicts device movement to facilitate accurate decision making of the bandwidth management.

Abstract: A method of channel access procedure and QoS provisioning is proposed. When more than one user equipments (UEs) contend uplink transmission for a given time slot in an unlicensed band, uplink listen-before-talk (LBT) scheme should perform in a proper way to reflect service prioritization. The base station first determines the Channel Access Priority (CAP) for uplink LBT, and then signals such CAP to the UE via PDCCH. Upon receiving the CAP, the UE performs LBT procedure with corresponding CAP before uplink transmission. For example, the CAP can be determined based on QoS class identifier (QCI) of the radio bearer or based on the MAC layer logical channel prioritization (LCP).

Abstract: A flexible and efficient physical downlink control channel (PDCCH) signaling scheme that schedules physical uplink shared channel (PUSCH) transmission over multiple subframes with Hybrid Automatic Retransmission (HARQ) support is proposed. The PDCCH has a downlink control information (DCI) format that schedules PUSCH transmission over multiple subframes. The PUSCH transmission is associated with multiple HARQ processes with non-consecutive HARQ process IDs. Furthermore, the DCI format uses joint signaling to combine HARQ process indexes, new data indication (NDI), and redundancy version (RV) to reduce signaling overhead.

Abstract: LWA (LTE/WLAN Aggregation) is a tight integration at radio level which allows for real-time channel and load aware radio resource management across WLAN and LTE to provide significant user perceived throughput (UPT) improvement. When enabling LWA, packets are routed to a base station (eNB) for performing PDCP functionalities as an LTE PDU. Afterwards, the eNB can dispatch the PDU either delivered over LTE link or WLAN link. The UPT improvement depends on how the eNB dispatches the PDU over LTE link or WLAN link. In one novel aspect, the eNB can acquire channel information, load information, and throughput estimation regarding with WLAN link and LTE link. As a result, the eNB can optimize UPT and LWA PDU dispatching algorithm.

Abstract: A physical random access channel (PRACH) waveform design to satisfy the requirements on the occupied channel bandwidth in eLAA wireless communications network is provided. In one alternative, PRACH comprises multiple segments in the time/frequency domain in one subframe. In another alternative, PRACH comprises multiple segments in the time/frequency domain across two or more subframes by using inter-subframe hopping. In one advantageous aspect, PDCCH triggers the dynamic allocation of the PRACH resource to facilitate the listen-before-talk (LBT) channel access procedure in unlicensed carriers. The aperiodic and dynamic allocation of PRACH resource improves efficiency and PRACH success rate.

Abstract: A method of reporting UE measurement state information in RLF report is provided. A UE performs radio measurements of a serving cell and neighbor cells in a mobile communication network. The UE evaluates a measurement reporting criteria and attempts to access the network to deliver a measurement report if the criteria is met. The UE then detects a radio link failure or a handover failure event and reconnects to the network by performing RRC reestablishment or RRC establishment. Finally, the UE transmits a failure event report to the network. The failure event report comprises UE measurement state information corresponds to the failure event. The UE measurement state information helps the network to determine whether to apply corrective actions to mitigate the failure.
