Abstract
A method implemented by an access node includes transmitting, by the access node, a wake up signal (WUS) prior to a control channel occurring within an associated discontinuous reception (DRX) ON period, wherein the WUS is transmitted using a first beam, and transmitting, by the access node, the control channel during the associated DRX ON period, wherein the control channel is transmitted on a control resource set (CORESET) using a second beam, wherein the first and second beams share a common quasi-colocated (QCL) source.

-51. (canceled)
A method implemented by a user equipment (UE), the method comprising:
- determining, by the UE, that a media access control (MAC) entity of the UE will be in Active Time at an expected transmission time of a first wake up signal (WUS), wherein the first WUS indicates if a physical downlink control channel (PDCCH) transmission is expected during a first DRX ON period following the expected transmission time of the first WUS;
- and
- deactivating, by the UE, WUS reception of the UE during the expected transmission time of the first WUS in response to determining that the MAC entity of the UE is in Active Time.
A user equipment (UE) comprising:
- a processor;
- and
- a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
- determine that a media access control (MAC) entity of the UE will be in Active Time at an expected transmission time of a first wake up signal (WUS), wherein the first WUS indicates if a physical downlink control channel (PDCCH) transmission is expected during a first DRX ON period following the expected transmission time of the first WUS;
- and
- deactivate WUS reception of the UE during the expected transmission time of the first WUS in response to determining that the MAC entity of the UE is in Active Time.
A method implemented by an access node, the method comprising:
- determining, by the access node, that a media access control (MAC) entity of a user equipment (UE) will be in Active Time during a predetermined window for transmitting a wake up signal (WUS) prior to a DRX ON period;
- and base thereon
- not transmitting, by the access node, the WUS to the UE during the predetermined window.
