Frequency hopping design for grant-free transmission in mobile communications
Various solutions for frequency hopping design for grant-free transmission with respect to user equipment and network apparatus in mobile communications are described. An apparatus may receive a frequency hopping pattern from a network node. The apparatus may determine a frequency hopping location according to the frequency hopping pattern. The apparatus may perform an uplink grant-free transmission according to the frequency hopping position. The frequency hopping pattern may comprise user equipment specific information.
