摘要： A method may include determining, by the network node for a flow, a plurality of reliability targets, wherein each reliability target of the plurality of reliability targets is associated with a different number of consecutive packet transmission errors for the flow and/or associated with a different value or range of values of a remaining survival time for the flow; determining, by the network node for a flow, a number of consecutive packet transmission errors or a remaining survival time for the flow; and determining, by the network node, a reliability target of the plurality of reliability targets, for a next packet transmission for the flow based on at least one of the number of consecutive packet transmission errors or the remaining survival time for the flow.

摘要： 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.

摘要： Various communication systems may benefit from inter-operator device-to-device operation. For example, communication systems of the third generation partnership project (3GPP) long term evolution (LTE) advanced (LTE-A) release12/13 (Rel-12/13) or future releases may use such operation with respect to D2D communications. A method can include preparing, at a network element operated by an operator, radio resource information related to one or more operators other than the operator. The method can also include broadcasting, by the network element, the radio resource information. The radio resource information can be configured to permit a user equipment served by the network element to perform device-to-device discovery and/or communication with another user equipment served by at least one of the one or more operators.

摘要： According to an example embodiment, a method may include receiving, by a user device in a wireless network, an uplink grant, the uplink grant indicating granted resources having a priority level; determining, by the user device, whether or not information to be transmitted has a priority level that matches the priority level of the granted resources; and transmitting, by the user device, the information via at least a portion of the granted resources, and an indication of whether or not a priority level of the information matches a priority level of the granted resources.

摘要： The use of PUCCH resources can be more efficient such as by sharing PUCCH resources between URLLC UEs and non-URLLC UEs in a controllable way enhanced with a smart deterministic downlink polling when needed. A method comprises receiving, by a user equipment from a network node of a communication network, information comprising a given physical uplink control channel resource instance allocated to the user equipment, wherein the physical uplink control channel resource instance is allocated to more than one user equipment including the user equipment; signaling the network node using an allocated physical uplink control channel resource instance in a given sub-frame; and, receiving polling form the network node, wherein the polling comprises an uplink grant.

摘要： This document discloses a solution for assisting transmissions in a wireless network. According to an aspect, a method comprises: monitoring, by a wireless device, a radio resource for a data packet transmitted by a source device to a sink device and capturing the data packet from the radio resource; decoding the data packet by the wireless device; determining, by the wireless device, that the sink device failed in decoding the data packet and that the wireless device is an assisting transmitter for retransmission of the data packet; and upon said determining, determining by the wireless device a radio resource for the retransmission and performing the retransmission of the data packet in the determined radio resource and together with the source device.

摘要： A method, apparatus and computer program in which an apparatus exchanges wirelessly information with a public land mobile network. The apparatus detects a wireless device to device discovery initiation instruction from the public land mobile network and responsively: sends one or more wireless discovery signal transmissions for a peer device or to monitor wireless discovery signal transmissions sent by a peer device; and directly communicates wirelessly with a peer device that indicates having received the wireless discovery signal transmission or from which the apparatus has detected a wireless discovery signal transmission in result of the monitoring of wireless discovery signal transmissions.
