A method for reducing power consumption of a terminal that communicates with a base station in a mobile communication system using a multi-carrier structure composed of a primary component carrier and at least one secondary component carrier comprises: receiving a discontinuous reception (DRX) parameter group for multi carriers from the base station; and setting the multi carriers to the same parameter value, by using the received parameter group. The method for reducing power consumption of the terminal further comprises: performing a downlink control channel receive operation on each carrier according to a DRX cycle. As the base station in the mobile communication system using the multi-carrier structure simplifies the DRX process for reducing power consumption of a terminal by reducing signaling load for the multi-carrier control of the terminal, it becomes possible to reduce power consumption of the terminal.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment or a base station may determine that a condition for entering a reduced monitoring state is satisfied, wherein the reduced monitoring state uses at least one of: a diminished radio frequency chain configuration, a diminished channel monitoring configuration, a restriction on receiving or transmitting a shared channel or a control channel, or a combination thereof; and communicate using the reduced monitoring state. Numerous other aspects are provided.

A method performed by a user equipment (UE) in a wireless communication system is provided. The method comprises: receiving, from a base station, higher layer signaling comprising a power saving offset (PS-offset) indicating a first start time when the UE starts, prior to a second start time of a drx-onDuration timer, monitoring physical downlink channel (PDCCH) for downlink control information (DCI) notifying power saving information outside a discontinuous reception (DRX) active time and parameters indicating a search space; identifying at least one PDCCH monitoring occasion for the DCI based on the PS-offset and the parameters indicating the search space; and monitoring the DCI on the at least one PDCCH monitoring occasion.

A communications device is configured to receive in a wireless communications systems using discontinuous reception. The communications device is configured to receive by determining a valid number of search spaces from which a wake-up signal, WUS, can be validly received during a power saving monitoring period. The valid number of search spaces is one or more of a plurality of search spaces of a downlink physical control channel of a wireless access interface provided by a wireless communications network for a WUS. The power saving monitoring period can be monitored by a receiver of the communications device in a low power state, the WUS being decodable with more relaxed processing requirements, and the WUS indicating that the receiver of the communications device should be powered up to a higher power state to receive signals in a discontinuous receiving on, DRX_ON, period.

If a secure element accesses a resource that is separate from the secure element, conducting a secure transaction can be inefficient in terms of power or time. Power usage is inefficient if the resource is never permitted to sleep, and transaction time is inefficient if the resource is permitted to sleep, and the user experiences a delay. To enable dual efficiency, a resource entity is permitted to be powered down. The resource entity is then powered up speculatively by an activation controller. The activation controller predicts an upcoming secure transaction based on sensor output, such as a position fix or a detected electromagnetic field. Based on monitored sensor output, the activation controller issues an activation signal to power up the secure element or the resource entity prior to initiation of the upcoming secure transaction. Thus, power can be conserved without introducing a transaction-processing latency.
