Method, device, and system for power saving in wireless networks

A method performed by a wireless communication node in a wireless network, comprising:

• transmitting, to a UE in the wireless network, a configuration message comprising configuration information associated with a Physical Downlink Control Channel (PDCCH) monitoring behavior set;
• and
• transmitting, to a UE in the wireless network, a control message indicating a PDCCH monitoring behavior in the PDCCH monitoring behavior set, wherein the control message triggers the UE to determine a PDCCH monitoring behavior based on the control message, the control message indicates the PDCCH monitoring behavior in the PDCCH monitoring behavior set via a field in the control message;
• wherein the method further comprises determining a bit width of the field;
• the control message is transmitted via a first serving cell in a serving cell group;
• the control message triggers the UE to apply a first PDCCH monitoring behavior in the first serving cell according to the field, wherein in response to a bit-width of the field being larger than a target bit-width required for indicating a PDCCH monitoring behavior for a second serving cell, a target field is obtained by truncating the field to the target bit-width;
• and the second PDCCH monitoring behavior is applied in the second serving cell according to the target field;
• and
• the control message triggers the UE to apply a second PDCCH monitoring behavior in the second serving cell in the serving cell group according to the field, wherein in response to a bit-width of the field being less than a target bit-width required for indicating a PDCCH monitoring behavior for the second serving cell, 0 is prepended or appended to the field to obtain a target field with the target bit-width, and the second PDCCH monitoring behavior is applied in the second serving cell according to the target field.

A device for wireless communication comprising a memory for storing computer instructions and a processor in communication with the memory, wherein, when the processor executes the computer instructions, the processor is configured to implement the following:

• receiving, from a wireless communication node in a wireless network, a configuration message comprising configuration information associated with a Physical Downlink Control Channel (PDCCH) monitoring behavior set;
• receiving, from the wireless communication node, a control message indicating a PDCCH monitoring behavior in the PDCCH monitoring behavior set;
• and
• determining a PDCCH monitoring behavior based on the control message, wherein the control message indicates the PDCCH monitoring behavior in the PDCCH monitoring behavior set via a field in the control message;
• wherein the processor is configured to further implement determining a bit width of the field;
• wherein the control message is received from a first serving cell in a serving cell group, and
• the processor is configured to further implement;
• applying a first PDCCH monitoring behavior in the first serving cell according to the field;
• and
• applying a second PDCCH monitoring behavior in a second serving cell in the serving cell group according to the field;
• wherein the processor is configured to implement applying the second PDCCH monitoring behavior in the second serving cell in the serving cell group according to the field by one of the following:
• in response to a bit-width of the field being larger than a target bit-width required for indicating a PDCCH monitoring behavior for the second serving cell:
• obtaining a target field by truncating the field to the target bit-width;
• and applying the second PDCCH monitoring behavior in the second serving cell according to the target field;
• or
• in response to a bit-width of the field being less than a target bit-width required for indicating a PDCCH monitoring behavior for the second serving cell:
• prepending or appending 0 to the field to obtain a target field with the target bit-width;
• and applying the second PDCCH monitoring behavior in the second serving cell according to the target field.
