Power saving for time-domain scheduling of downlink data

A wireless device comprising:

• one or more processors;
• and
• one or more memories storing instructions that, when executed by the one or more processors, cause the wireless device to:
• receive configuration parameters indicating a minimum scheduling offset value of a bandwidth part (BWP) of a cell, wherein the minimum scheduling offset value is a minimum value of one or more possible scheduling offset values, in a time domain, between downlink control information (DCI) and a downlink data channel schedulable by the DCI;
• receive a first DCI comprising:
• a BWP index of the BWP;
• and
• a field indicating whether to apply the minimum scheduling offset value, wherein the field being a first value indicates to apply the minimum scheduling offset value, and wherein the field being a second value indicates not to apply the minimum scheduling offset value;
• receive a second DCI indicating a scheduling offset value between the second DCI and a downlink data channel scheduled by the second DCI, wherein the scheduling offset value is greater than, or equal to, the minimum scheduling offset value based on the field;
• and
• apply the scheduling offset value to determine a duration of micro-sleep after receiving the second DCI and responsive to the field being the first value.

A base station comprising:

• one or more processors;
• and
• one or more memories storing instructions that, when executed by the one or more processors, cause the base station to:
• transmit configuration parameters indicating a minimum scheduling offset value of a bandwidth part (BWP) of a cell, wherein the minimum scheduling offset value is a minimum value of one or more possible scheduling offset values, in a time domain, between downlink control information (DCI) and a downlink data channel schedulable by the DCI;
• transmit a first DCI comprising:
• a BWP index of the BWP;
• and
• a field indicating whether to apply the minimum scheduling offset value, wherein the field being a first value indicates to apply the minimum scheduling offset value, and wherein the field being a second value indicates not to apply the minimum scheduling offset value;
• and
• transmit a second DCI indicating a scheduling offset value between the second DCI and a downlink data channel scheduled by the second DCI, wherein the scheduling offset value is greater than, or equal to, the minimum scheduling offset value based on the field,
• wherein the field being the first value and the scheduling offset value being greater than, or equal to, the minimum scheduling offset value is an indication to apply the scheduling offset value to determine a duration of micro-sleep.
