1. A method performed by user equipment (UE) in a 5G new radio (NR) in a licensed or an unlicensed spectrum environment, comprising:
receiving configuration information from a base station, wherein the configuration information comprises information for finding downlink control information (DCI);
being polled by receiving the DCI that includes indication of a physical uplink control channel (PUCCH) resource for the UE to transmit a dynamic scheduling request (SR);
finding the DCI based on the configuration information;
finding the PUCCH resource based on a symbol location that is determined relative to a position of a PUCCH resource indicator (PRI) in the DCI; and
transmitting the dynamic SR in a PUCCH message based on the PUCCH resource, wherein uplink grant is performed based on the dynamic SR, wherein transmitting the dynamic SR includes transmitting a listen before talk (LBT) band for the network to identify a resource for the uplink grant.
