INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract A method performed by a User Equipment (UE) includes receiving, through Radio Resource Control (RRC) signaling from a Base Station (BS), an indication indicating a dormancy cell group having at least a first serving cell and a second serving cell, receiving, through Physical Layer (PHY) signaling from the BS, a signal associated with a specific Downlink Control Information (DCI) format indicating a dormant behavior applicable to all serving cells in the dormancy cell group, wherein the signal indicates the dormant behavior via a single bit, applying the dormant behavior to the first serving cell and the second serving cell when the signal indicates that the dormant behavior is to be activated, and not applying the dormant behavior to the first serving cell and the second serving cell when the signal indicates that the dormant behavior is to be deactivated. ## Claims ### Claim 1 A method performed by a User Equipment (UE), the method comprising: receiving, through Radio Resource Control (RRC) signaling, from a Base Station (BS), an indication indicating a dormancy cell group having at least a first serving cell and a second serving cell; receiving, through Physical Layer (PHY) signaling, from the BS, a signal associated with a specific Downlink Control Information (DCI) format indicating a dormant behavior applicable to all serving cells in the dormancy cell group, wherein the signal indicates the dormant behavior via a single bit; applying the dormant behavior to the first serving cell and the second serving cell when the signal indicates that the dormant behavior is to be activated; and forgoing applying the dormant behavior to the first serving cell and the second serving cell when the signal indicates that the dormant behavior is to be deactivated. ### Claim 2 (depends on 1) The method of claim 1, further comprising: receiving, from the BS, a wake up signal indicating the dormant behavior of the dormancy cell group, the wake up signal further including power saving information; applying the dormant behavior to the first serving cell and the second serving cell when the wake up signal indicates that the dormant behavior of the dormancy cell group is to be activated; and forgoing applying the dormant behavior to the first serving cell and the second serving cell when the wake up signal indicates that the dormant behavior of the dormancy cell group is to be deactivated. ### Claim 3 (depends on 2) The method of claim 2, wherein the power saving information includes a physical downlink control channel (PDCCH) monitoring behavior within an on-duration time of a Discontinuous Reception (DRX) mechanism. ### Claim 4 (depends on 2) The method of claim 2, wherein the wake up signal indicates the dormant behavior applicable to the all serving cells in the dormancy cell group via a single bit. ### Claim 5 (depends on 1) The method of claim 1, wherein the dormant behavior further includes at least one of performing Channel State Information (CSI) measurement, performing Automatic Gain Control (AGC), and performing beam management. ### Claim 6 (depends on 1) The method of claim 1, wherein the dormant behavior applicable to the first serving cell is applied on an active Bandwidth Part (BWP) of the first serving cell when the first serving cell is activated. ### Claim 7 (depends on 1) The method of claim 1, wherein the dormancy cell group includes only serving cells that are Secondary Cells (Scells). ### Claim 8 (depends on 1) The method of claim 1, wherein the indication indicates, to the UE, each serving cell of a plurality of serving cells that belongs to the dormancy cell group via a cell index of the serving cell. ### Claim 9 A User Equipment (UE) comprising: one or more non-transitory computer-readable media storing one or more computer-executable instructions; and at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the one or more computer-executable instructions to cause the UE to: receive, through Radio Resource Control (RRC) signaling from a Base Station (BS), an indication indicating a dormancy cell group having at least a first serving cell and a second serving cell; receive, through Physical Layer (PHY) signaling from the BS, a signal associated with a specific Downlink Control Information (DCI) format indicating a dormant behavior applicable to all serving cells in the dormancy cell group, wherein the signal indicates the dormant behavior via a single bit; apply the dormant behavior to the first serving cell and the second serving cell when the signal indicates that the dormant behavior is to be activated; and forgo applying the dormant behavior to the first serving cell and the second serving cell when the signal indicates that the dormant behavior is to be deactivated. ### Claim 10 (depends on 9) The UE of claim 9, wherein the at least one processor is further configured to execute the one or more computer-executable instructions to cause the UE to: receive, from the BS, a wake up signal indicating the dormant behavior of the dormancy cell group, the wake up signal further including power saving information; apply the dormant behavior to the first serving cell and the second serving cell when the wake up signal indicates that the dormant behavior of the dormancy cell group is to be activated; and forgo applying the dormant behavior to the first serving cell and the second serving cell when the wake up signal indicates that the dormant behavior of the dormancy cell group is to be deactivated. ### Claim 11 (depends on 10) The UE of claim 10, wherein the power saving information includes a physical downlink control channel (PDCCH) monitoring behavior within an on-duration time of a Discontinuous Reception (DRX) mechanism. ### Claim 12 (depends on 10) The UE of claim 10, wherein the wake up signal indicates the dormant behavior applicable to the all serving cells in the dormancy cell group via a single bit. ### Claim 13 (depends on 9) The UE of claim 9, wherein the dormant behavior further includes at least one of performing Channel State Information (CSI) measurement, performing Automatic Gain Control (AGC), and performing beam management. ### Claim 14 (depends on 9) The UE of claim 9, wherein the dormant behavior applicable to the first serving cell is applied on an active Bandwidth Part (BWP) of the first serving cell when the first serving cell is activated. ### Claim 15 (depends on 9) The UE of claim 9, wherein the dormancy cell group includes only serving cells that are Secondary Cells (SCells). ### Claim 16 (depends on 9) The UE of claim 9, wherein the indication indicates, to the UE, each serving cell of a plurality of serving cells that belongs to the dormancy cell group via a cell index of the serving cell.
