Abstract: Techniques for performing sidelink discovery with user equipment (UE) to UE relay are provided. An initiating UE initiates a sidelink discovery solicitation message toward relay UEs and responding UEs. A relay UE can facilitate the discovery between two or more UEs by monitoring for sidelink discovery solicitation messages and sidelink discovery solicitation responses. A responding UE in receipt of a sidelink solicitation message responds toward a relay UE and/or initiating UE via communication method that may depend on various factors. The communication method may include non-unicast communication, such as broadcast or multicast, to reduce signaling overhead in comparison to unicast communication methods.

Abstract: An SL UE that detects a resource conflict associated with a transmitting UE may be able to indicate this resource conflict by transmitting inter-UE coordination information over a PSFCH resource determined based on a group member ID of the transmitting UE. This may be different from transmitting HARQ feedback via a PSFCH resource determined based on a group member ID of the detecting UE.

Abstract: Embodiments concern managing traffic in a radio device. While classifying user-plane packets from multiple applications according to quality of service requirements, a specific user-plane packet is classified as/determined to be a predetermined special-type packet (e.g., the special-type packets establish a new TCP/IP connection for a newly activated application). Based on that, that specific user-plane packet is mapped to a pre-defined radio bearer associated with a preconfigured priority, for example a highest priority among all bearers to which any of these user-plane packets from the multiple applications are mapped. Then all the mapped user-plane packets are scheduled for transmission according to their respective priorities. For example, the specific user-plane packet could be a SDU having a SYN, SYN-ACK or ACK, and the network convergence sub-layer (NCS) constructs a L2 NCS PDU using a designated format with the SDU in the payload and context information in the header.

Abstract: Various communication systems may benefit from improved network management. A method may include receiving an indication of a subset of a cluster of local cells at an ultra-reliable, low latency communications user equipment using multi-connectivity. The method may also include receiving rules for radio performance monitoring, wherein the rules include a packet error rate threshold for individual radio links of the multi-connectivity. In addition, the method may include determining based on the rules and the radio performance monitoring whether to skip the monitoring of one or more cells of the subset of local cells. The skip may be short-term or long term. Further, the method may include communicating to the subset a report based on the radio performance monitoring and whether to skip the monitoring of one or more cells of the subset of local cells.

Abstract: A method is provided including configuring, by a network node, a set of resources to be used by at least one user equipment for transmitting a first type of uplink data; receiving from the at least one user equipment information that indicates that at least one resource in the set of resources comprises a second type of uplink data different than the first type of uplink data; and decoding data received on the at least one resource based on the information.

Abstract: There is provided an improved solution for performing beacon broadcasting in a device-to-device communication network. The solution comprises selecting, by a node capable of entering a device-to-device communication network, a channel for broadcasting wherein the selection is based on at least one of the following: the characteristics of the node and the state of the node; and causing a broadcast of information related to at least part of the properties of the node on the selected channel.

Abstract: A user equipment (UE) selects first and second radio resources from respective first and second pools of radio resources. In one example these are primarily allocated for contention-free and scheduling-based channel access, respectively. Content to duplicate in parallel communications is selected based at least on a characteristic of uplink data waiting to be sent (such as size) and/or on the selected first and second radio resources (such as timing difference between them). The UE transmits the selected content on each of the selected first and second radio resources. In the examples the content to duplicate was selected from among the uplink data to send and a scheduling request message. In various embodiments one of these transmissions indicates it's a duplicate, and the duplicated scheduling request message is transmitted on the first resource with the uplink data. These teachings are particularly useful for URLLC data.

Abstract: Various communication systems may benefit from minimization of service interruption. For example, certain wireless communication systems may benefit from support for minimization of service interruption with device-to-device-based user-equipment-to-network relay. A method can include determining that a layer 3 relay is selected for a remote user equipment. The method can also include sending an indication to a serving access node about the relay selection.
