    Abstract: For a source stream of input data where FEC scheme(s) have been used to create a repair stream, transmitting by a network node packet(s) comprising data of the source stream or the repair stream packaged as at least part of PDU(s). An ARQ or HARQ process is applied to the PDU(s). The network node receives feedback information as part of the process corresponding to the PDU(s), including positive ACK/NACK response for the PDUs. The retransmissions of the negatively acknowledged PDU(s) are controlled when the FEC scheme is known not to be able to compensate for loss(e)s of packet(s) contained in the PDU(s) indicated as being negatively acknowledged. A UE receives packet(s), determines loss(es), and, in response to a determination the FEC scheme is known to be able to recover from the loss(es), sends at least one ACK for any lost packets that correspond to the one or more loss(es).

    Abstract: Handover failure modes are identified by logging information associated with at least one of a handover failure or a radio link failure. The information identifies whether or not a user equipment was engaged in an exchange of at least one of data traffic or control traffic with a network at the time that the handover failure or radio link failure occurred. The information is stored in a non-transitory computer-readable medium, and the information is reported to the network. The information is reported using a radio link failure or connection failure information signaling message. The severity of the handover failure or radio link failure is evaluated based upon the information.

    Abstract translation: 通过记录与切换故障或无线电链路故障中的至少一个相关联的信息来识别切换故障模式。 该信息识别在切换失败或无线电链路故障发生时用户设备是否参与与网络的数据业务或控制业务中的至少一个的交换。 该信息存储在非暂时的计算机可读介质中，并将信息报告给网络。 使用无线电链路故障或连接故障信息信令消息来报告信息。 基于该信息来评估切换失败或无线电链路故障的严重性。

    Abstract: Embodiments of the present disclosure relate to a method for confirming uplink semi-persistent scheduling deactivation and a terminal device. In example embodiments, an indication of uplink semi-persistent scheduling deactivation is received from a base station while the terminal device stores data available for uplink transmission. Then, confirmation of the deactivation is sent to the base station. Such confirmation of the deactivation may notify the base station that the terminal device has received the indication of the uplink semi-persistent scheduling deactivation and further that the uplink semi-persistent scheduling will be deactivated at the terminal device.
