Abstract: Example embodiments of the present disclosure relate to logical channel prioritization. A method includes obtaining an uplink grant from a network device, the uplink grant indicating uplink resources for transmission to the network device and selecting a logical channel prioritization setting from a plurality of logical channel prioritization settings based on a predetermined policy related to the uplink grant, the logical channel prioritization settings defining different sets of prioritization parameters for uplink data in at least one logical channel and uplink control information in occupying the uplink resources. The method further includes generating, based on the logical channel prioritization setting, a packet data unit including at least one of the uplink control information or at least one part of the uplink data for transmission to the network device using the uplink resources. In this way, adaptive and dynamic prioritization across logical channels can be achieved at the terminal device.

Abstract: Systems, methods, apparatuses, and computer program products for radio link capability exposure for ultra-reliable low-latency communications (URLLC) and time sensitive communications (TSC). A method may include receiving, from a core network element, configuration of a reliability threshold for sending a failure report and/or a radio link capability report. The method may also include, when the reliability threshold is reached, sending a failure report to the core network element indicating that a required reliability cannot be fulfilled. The method may further include receiving instructions, from the core network element, to perform an action to address the unfulfilled reliability.

Abstract: The present disclosure relates generally to the field of wireless communications and, in particular, to techniques for issuing criteria-based retransmission grants for pending Media Access Control (MAC) Protocol Data Units (PDUs) generated and buffered in a user equipment (UE) in a wireless communication network. In particular, the UE is configured with at least one criterion for determining which of the pending MAC PDUs stored in the UE (e.g., in the HARQ buffers) could be transmitted by using radio resources of a retransmission grant issued by a network node. In other words, the UE should determine whether at least one of the pending MAC PDUs meets the at least one criterion. The at least one criterion may be signalled to the UE either in the retransmission grant or independently from the retransmission grant. If none of the pending MAC PDUs meets the at least one criterion, it is also allowed to apply the at least one criterion to a new MAC PDU, thereby making it possible to use the retransmission grant issued by the network node as a new transmission grant (provided that the new MAC PDU meets the at least one criterion). Thus, by using such a retransmission grant, it is possible to provide efficient MAC PDU recovery and resource usage.
