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 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.

Abstract: 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.
