Abstract: To facilitate LWA PDCP setting/scheduling, a method of providing dynamic PDCP status report polling is proposed. To enhance scheduling efficiency, the transmitter (can be eNB from DL or UE for UL) can dynamically poll PDCP status report for LWA behavior. The polling can be done by a standalone PDCP control PDU or use reserved bit in PDCP data PDU. The triggering condition for PDCP status polling includes: PDCP without poll time exceeds a first threshold, PDCP without poll bytes exceeds a second threshold, PDCP without poll PDU numbers exceeds a third threshold, a data buffer is empty, and when LWA is deactivated.

Abstract: A communications apparatus includes a radio transceiver and a processor. The radio transceiver receives a plurality of feedback messages from a peer device. The feedback messages are transmitted by the peer device to indicate a result of UL data transmission. The processor analyzes content of the feedback messages to determine a preferred retransmission type of the peer device and records the preferred retransmission type of the peer device in a memory device. When the radio transceiver receives a first UL grant message indicating transmission of a first UL data and the processor determines that a forthcoming first feedback message corresponding to the transmission of the first UL data is unable to be received, the processor determines whether to retransmit the first UL data according to the preferred retransmission type of the peer device.

Abstract: Various solutions for maintaining a radio resource control (RRC) connection with respect to user equipment and network apparatus in mobile communications are described. An apparatus may establish an RRC connection with a network node. The apparatus may transmit a layer 2 packet to maintain the RRC connection after a period of time without data transmission. The apparatus may transmit uplink data via the RRC connection without re-establishing the RRC connection.

Abstract: A communications apparatus includes a first radio frequency (RF) signal processing device, a first baseband signal processing device and a processor. The first RF signal processing device transceives a plurality of RF signals to and from a peer communications apparatus to communicate with the peer communications apparatus in compliance with a first Radio Access Technology (RAT) and processing the RF signals. The first baseband signal processing device processes a plurality of baseband signals corresponding to the RF signals. The processor obtains an uplink scheduling indicating a predetermined time assigned by the peer communications apparatus to transmit uplink data from the baseband signals, determines whether to transmit the uplink data at the predetermined time according to a gap-creation criterion, and transmits padding instead of the uplink data to the peer communications apparatus at the predetermined time when the gap-creation criterion is satisfied.
