Power saving for downlink control channel monitoring in unlicensed bands

A method for wireless communications at a base station, comprising:

• transmitting, using a first set of resources on a wireless channel for downlink control channel signaling, one or more downlink control channel signals during a first set of one or more downlink control channel monitoring occasions;
• performing a directional listen-before-talk procedure on one or more beams;
• determining that the directional listen-before-talk procedure was successful for a first subset of the one or more beams and that the directional listen-before-talk procedure failed for a second subset of the one or more beams;
• and
• transmitting, to a first UE using a second set of resources comprising the second subset of the one or more beams, a control message comprising an instruction to modify the monitoring of the wireless channel using the first set of resources during a second set of one or more downlink control channel monitoring occasions.

An apparatus for wireless communications at a user equipment (UE), comprising:

• a first interface:
• a second interface;
• and
• a modem coupled to the first interface and the second interface, wherein the modem is configured to:
• monitor, using a first set of resources, a wireless channel for downlink control channel signaling during a first set of downlink control channel monitoring occasions according to a first monitoring pattern;
• obtain over the second interface, using a second set of resources, a control message comprising an instruction to modify the monitoring of the wireless channel using the first set of resources;
• and
• monitor, based at least in part on the control message, the wireless channel for downlink control channel signaling during a second set of downlink control channel monitoring occasions according to a second monitoring pattern.

An apparatus for wireless communications at a base station, comprising:

• a first interface;
• a second interface;
• and
• a modem coupled to the first interface and the second interface, wherein the modem is configured to:
• output via the first interface, using a first set of resources on a wireless channel for downlink control channel signaling, one or more downlink control channel signals during a first set of one or more downlink control channel monitoring occasions;
• perform a directional listen-before-talk procedure on one or more beams;
• determine that the directional listen-before-talk procedure was successful for a first subset of the one or more beams and that the directional listen-before-talk procedure failed for a second subset of the one or more beams;
• and
• output via the first interface, to a first UE using a second set of resources comprising the second subset of the one or more beams, a control message comprising an instruction to modify the monitoring of the wireless channel using the first set of resources during a second set of one or more downlink control channel monitoring occasions.
