Techniques and apparatuses for control channel monitoring using a wakeup signal

A method of wireless communication, comprising:

• identifying, by a base station, a wakeup signal resource associated with a user equipment (UE) based at least in part on a control channel search space resource associated with the UE, wherein the wakeup signal resource maps to the control channel search space resource and precedes the control channel search space resource;
• determining, by the base station, that a control channel search space, associated with the control channel search space resource, is to include control information associated with the UE;
• and
• transmitting, by the base station, a wakeup signal in the wakeup signal resource based at least in part on determining that the control channel search space is to include control information associated with the UE, wherein the wakeup signal indicates whether the UE is to initiate a wakeup procedure to monitor the control channel search space resource of sleep during the control channel search space resource.

A user equipment (UE) for wireless communication, comprising:

• memory;
• and
• one or more processors coupled to the memory, the memory and the one or more processors configured to:
• identify a wakeup signal resource associated with the UE based at least in part on a control channel search space resource associated with the UE, wherein the wakeup signal resource maps to the control channel search space resource and precedes the control channel search space resource;
• monitor the wakeup signal resource for an indication of whether to monitor the control channel search space resource;
• and
• monitor the control channel search space resource when the monitoring of the wakeup signal resource indicates that the control channel search space resource is to be monitored.

A base station for wireless communication, comprising:

• memory;
• and
• one or more processors coupled to the memory, the memory and the one or more processors configured to:

• determine that a control channel search space, associated with the control channel search space resource, is to include control information associated with the UE;
• and
• transmit a wakeup signal in the wakeup signal resource based at least in part on determining that the control channel search space is to include control information associated with the UE, wherein the wakeup signal indicates whether the UE is to initiate a wakeup procedure to monitor the control channel search space resource of sleep during the control channel search space resource.
