## Abstract

Some aspects of this disclosure include apparatuses and methods for implementing mechanisms for downlink control information between an electronic device (for example, a UE) and a network for cell detection and measurement. For example, some aspects relate to an electronic device including a transceiver and a processor communicatively coupled to the transceiver. The processor monitors one or more paging occasions within a discontinuous repetition cycle (DRX) and can make a determination of one or more paging occasions within the DRX to not monitor. Each paging occasion may include a transmission by the network of downlink control information for one or more paging messages.

## Claims

a transceiver configured to wirelessly communicate with a wireless network; and
a processor, communicatively coupled to the transceiver, configured to:
monitor, using the transceiver, at least one of a plurality of paging occasions within a discontinuous repetition cycle (DRX);
determine one or more of the plurality of paging occasions to not monitor, wherein the plurality of paging occasions include a transmission by the wireless network of downlink control information (DCI) for one or more paging messages; and
determine whether to receive, using the transceiver, the at least one of the plurality paging messages based on whether the DCI includes an address associated with the UE.

### Claim 2 (depends on 1)

The UE of claim 1, wherein the processor is further configured to:
define a paging inactivity timer corresponding to a value associated with the at least one of the plurality of paging occasions to monitor; and
perform the monitoring, using the transceiver, of the at least one of the plurality of paging occasions within the DRX based on the paging inactivity timer,
wherein the processor is configured to determine the one or more of the plurality of paging occasions to not monitor is based on a status of the paging inactivity timer and
wherein the value associated with the at least one of the plurality of paging occasions represents at least one of a duration period or a number of monitoring occasions.

### Claim 3 (depends on 1)

The UE of claim 1, wherein the processor is further configured to initialize a paging inactivity timer after receiving, by the transceiver, the DCI, when the DCI is not addressed to an identifier associated with the UE.

### Claim 4 (depends on 3)

The UE of claim 3, wherein the processor is further configured to discontinue monitoring the at least one of the plurality of paging occasions based on the paging inactivity timer.

### Claim 5 (depends on 1)

The UE of claim 1, wherein the processor is configured to receive, from the wireless network, an indicator that includes configuration information for paging occasion monitoring behavior of the UE.

### Claim 6 (depends on 5)

The UE of claim 5, wherein the processor is configured to receive, from the wireless network, the indicator via an information element (IE) transmitted with a paging message, and
wherein the IE indicates whether additional paging occasions should be monitored by the UE.

### Claim 7 (depends on 5)

The UE of claim 5, wherein the processor is further configured to receive, from the wireless network, the indicator using Radio Resource Control (RRC) layer signaling,
wherein the indicator represents an instruction for the UE to discontinue paging occasion monitoring within the DRX based on a detection of a transmission by a base station (BS) and a determination that a paging identifier message transmitted by the BS does not include the address associated with the UE.

### Claim 8 (depends on 7)

The UE of claim 7, wherein the processor is further configured to receive, from the wireless network, a Demodulation Reference Signal (DMRS) signal to detect the transmission by the BS.

### Claim 9

A method, comprising:
