Control Information Monitoring Framework for Cellular Communication

A wireless device, comprising:

• a radio;
• and
• a processor operably coupled to the radio and configured to cause the wireless device to:
• receive, from a base station:
• a first control information monitoring configuration including a first periodic pattern comprising a first one or more slots for monitoring during respective periods of the first periodic pattern;
• and
• a second control information monitoring configuration including a second periodic pattern comprising a second one or more slots for monitoring during respective periods of the second periodic pattern, wherein the second periodic pattern has a different periodicity than the first periodic pattern,
• monitor a control channel for control information from the base station according to the first periodic pattern based on the first control information monitoring configuration, wherein according to the first periodic pattern, the wireless device monitors the control channel in a portion of each slot of the first one or more slots during the respective periods of the first periodic pattern;
• trigger, in response to receiving first control information during said monitoring of the control channel according to the first periodic pattern, control channel monitoring according to the second periodic pattern based on the second control information monitoring configuration, instead of monitoring the control channel according to the first periodic pattern, wherein said control channel monitoring according to the second periodic pattern includes monitoring the control channel for control information in a portion of each slot of the second one or more slots during the respective periods of the second periodic pattern;
• and
• monitor the control channel for control information from the base station according to the second periodic pattern.

An apparatus, comprising:

• a processor configured to cause a wireless device to:
• receive, from a base station:
• a first control information monitoring configuration including a first periodic pattern comprising a first one or more slots for monitoring during respective periods of the first periodic pattern;
• and
• a second control information monitoring configuration including a second periodic pattern comprising a second one or more slots for monitoring during respective periods of the second periodic pattern, wherein the second periodic pattern has a different periodicity than the first periodic pattern,
• monitor a control channel for control information from the base station according to the first periodic pattern based on the first control information monitoring configuration, wherein according to the first periodic pattern, the wireless device monitors the control channel in a portion of each slot of the first one or more slots during the respective periods of the first periodic pattern;
• trigger, in response to receiving first control information during said monitoring of the control channel according to the first periodic pattern, control channel monitoring according to the second periodic pattern based on the second control information monitoring configuration, instead of monitoring the control channel according to the first periodic pattern, wherein said control channel monitoring according to the second periodic pattern includes monitoring the control channel for control information in a portion of each slot of the second one or more slots during the respective periods of the second periodic pattern;
• and
• monitor the control channel for control information from the base station according to the second periodic pattern.

A method, comprising:

• at a base station:
• providing, to a wireless device:
• a first control information monitoring configuration including a first periodic pattern comprising a first one or more slots for monitoring during respective periods of the first periodic pattern;
• and
• a second control information monitoring configuration including a second periodic pattern comprising a second one or more slots for monitoring during respective periods of the second periodic pattern, wherein the second periodic pattern has a different periodicity than the first periodic pattern;
• providing, to the wireless device, first control information during a third slot of the first one or more slots according to the first periodic pattern based on the first control information monitoring configuration;
• and
• providing, to the wireless device, in response to providing the first control information during the third slot, second control information according to the second periodic pattern based on the second control information monitoring configuration, wherein providing the second control information according to the second periodic pattern includes providing the second control information during a fourth slot of the second one or more slots, wherein the fourth slot is subsequent to the third slot.
