A UE may receive, from a base station, a first and second configurations of first and second periodic resources, receive, from the base station, a metric for switching between the first and second configurations, and switching from the first configuration to the second configuration based on the metric received from the base station. The first and second configurations may be CG of uplink resources for uplink channels. The first and second configurations may indicate SPS resources for downlink channels. The base station may determine the metric based on at least one measurement of signal at the base station or scheduling requirements.
