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.
