    Abstract: An enhanced connection recovery upon lost RRC connection due to radio link failure (RLF) or handover failure (HOF) is proposed. A UE first establishes an RRC connection in a source cell in a mobile communication network. Later on, the UE detects a failure event and starts an RRC reestablishment procedure in a target cell to restore the RRC connection. In a first novel aspect, a fast NAS recovery process is applied to reduce the outage time in the target cell. In a second novel aspect, context fetching is used to reduce the outage time in the target cell. In a third novel aspect, a loss-less reestablishment procedure is proposed to reduce data loss during the connection recovery.

    Abstract: Methods for rate matching with soft buffer size setting at the transmitter and soft channel bits storage at the receiver for superposition coding are proposed. In the superposition coding scheme, a transport block intended to one UE needs to be decoded by another UE's receiver. However, the soft buffer sizes per code block of the two receivers may not be the same since the size depends on the UE category. The base station can signal the soft buffer size used at the transmitter for rate matching to the UEs for superposition decoding. A UE stores information bits associated with an interfering signal in its soft buffers in accordance with the soft buffer size used at the transmitter for rate matching. As a result, the UE can decode and subtract the interfering signal from the desired signal for superposition coding.

    Abstract: When the codeword level interference cancellation (CW-IC) is used at the receiver in conjunction with the superposition coding scheme at the transmitter, in order to guarantee the success of signal reception, restrictions of scheduling decisions in resource allocation of superposed transport blocks may occur. A method to mitigate the scheduling restrictions is proposed. For a low-geometry UE in NOMA operation, one sub-band is used as the basic scheduling unit. As a result, data in resource blocks scheduled for NOMA operation and data in resource blocks scheduled for other non-NOMA operation correspond to different transport blocks. Therefore, a high-geometric UE only needs to decode the data scheduled for NOMA. The base station does not need to impose additional scheduling restrictions and signaling overhead.
