摘要： A wireless communication device (412) replicates, at a Radio Link Control (RLC) layer of a protocol stack of the wireless communication device (412), an original packet associated to a particular service to provide one or more replicate packets. Each of the one or more replicate packets is a replication of the original packet. For each packet from among a set of packets consisting of the original packet and at least one of the one or more replicate packets, the wireless communication device (412) generates a transport block that comprises the packet and transmits the transport block to one or more base stations or transmission/reception points, TRPs, via a physical layer of the protocol stack of the wireless communication device (412).

摘要： Indication of Transmission Configuration Indication (TCI) states for aperiodic Channel State Information-Reference Signal (CSI-RS) with low configuration overhead is provided. More specifically, methods performed by a wireless device(s) and a base station(s) for indicating a configuration parameter(s) for triggering aperiodic CSI-RS are provided. The methods disclosed herein make it possible for triggering aperiodic CSI-RS with multiple options (e.g., any of indicated TCI states and/or Quasi Co-Located relationships). As a result, it is possible to significantly reduce configuration overhead related to indicating aperiodic CSI-RS.

摘要： Performing a superposed transmission in a wireless communications network. The superposed transmission includes a first signal intended for a first wireless device and a second signal intended for a second wireless device that are superposed and transmitted simultaneously by the network node on the same transmission resources. A first ratio and a second ratio of the total transmission power available for the superposed transmission are determined. The first ratio is to be used for the first signal and the second ratio is to be used for the second signal. Information indicating the first and/or second ratio is transmitted to at least the first wireless device and the superposed transmission to the first and second wireless device is performed simultaneously on the same transmission resources by transmitting the first signal using a transmission power according to the first ratio and the second signal using a transmission power according to the second ratio.

摘要： Systems and methods for reliable Medium Access Control (MAC) Control Element (CE) ACK/NACK confirmation are provided. In some embodiments, a method performed by a wireless device includes: being configured with at least one feedback enabled Hybrid Automatic Repeat Request (HARQ) process while the remaining HARQ processes of the wireless device have feedback disabled; receiving an activation/deactivation command requiring feedback, where the receiving uses the at least one feedback enabled HARQ process; and/or transmitting feedback regarding the activation/deactivation command. In this way, the wireless device is enabled to send HARQ ACK/NACK feedback related to critical activation/deactivation MAC CE commands in a Non-Terrestrial Network (NTN). Furthermore, in the presence of large one way delay, this ensures that there is no mismatch between the base station and the wireless device as to when the wireless device can assume the activation/deactivation information in the MAC CE command can takes effect at the wireless device.
