1. A user equipment (UE) apparatus comprising: at least one processor;
and at least one memory storing instructions that, when executed by the at least one processor, cause the UE apparatus at least to:
receive first configuration information from a network node, the first configuration information including information on a discontinue reception (DRX) cycle and a notification to monitor a physical downlink control channel (PDCCH) transmission carrying a wake-up indication, wherein the network node is one of a base station or a remote radio head,
wherein the first configuration information includes a location in a Downlink Control Information (DCI) format 2-6 of a wake-up indication bit is in indicated by a PSPositionDCI2-6, where:
the UE apparatus does not start a drx-onDuration Timer for a next DRX cycle when a value of a ‘PDCCH monitoring’ bit is ‘0’, and the UE apparatus starts a drx-onDuration Timer for a next DRX cycle when a value of the ‘PDCCH monitoring’ bit is ‘1’;
receive second configuration information from the network node, the second configuration information including:
configuration information for secondary cells (SCells) that are associated with the network node, and
a rule set, the rule set notifying the UE apparatus of which of one or more serving cells is active based on the network node at least one of assuming or knowing that the UE apparatus has not been able to receive a downlink control information of power saving (DCP);
first determine an overlap occurrence using the DRX cycle, the overlap occurrence occurring due to one or more portions of the DRX cycle overlapping with at least one first bandwidth part (BWP) active-time of a BWP of the PDCCH, wherein the first determining further includes:
monitoring for the wake-up indication on the active BWP during at least one first BWP active-time, and
second determine an on-duration of the DRX cycle coincides at least in part with the at least one first BWP active-time during the one or more portions of the DRX cycle, wherein the active BWP is one singular active BWP of the PDCCH, wherein during the monitoring for the wake-up indication, the UB apparatus is not required to monitor an entire downlink frequency of the PDCCH, wherein the wake-up indication is the DCP, the DCP being a notification for the UE apparatus to monitor the active BWP during at least one second BWP active-time,
wherein the DCP includes downlink control information with cyclic redundancy check scrambled by power saving radio network temporary identity;
activate the one or more serving cells, following the determining of the overlap occurrence, wherein each of the one or more serving cells is an SCell, wherein the SCell of the one or more serving cells is selected so that the selection is based on a serving cell index, wherein the SCell is selected so that it is at least one of a lowest index serving cell, a highest index serving cell, or in a case where multiple are selected the selection starts from the lowest index or the highest index;
conduct an operation of data communications with the network node using the one or more serving cells that are activated, wherein the operation includes conducting a random access channel (RACH) procedure; and
third determine to cease monitoring of the active BWP during the one or more portions of the DRX cycle,
wherein the activating including includes the UE apparatus commanding the one or more SCells to switch from a dormant state to a non-dormant state.
