Methods and apparatuses for a pdcch monitoring enhancement mechanism for xr traffic

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

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the UE to:
• receive first configuration information from a network node, wherein the first configuration information includes at least one of:
• configuration information regarding a first search space set group (SSSG), configuration information regarding a second SSSG, one or more groups of configuration information regarding discontinuous reception (DRX) for one or more serving cells in one or more DRX groups, or configuration information of SSSG applying associated with DRX operation of the UE;
• and
• start monitoring a physical downlink control channel (PDCCH) transmission according to search space sets within the first SSSG at a first time point for the one or more serving cells within the one or more DRX groups based on the configuration information of applying SSSG.

A method performed by a user equipment (UE), the method comprising:

• receiving first configuration information from a network node, wherein the first configuration information includes at least one of:
• configuration information regarding a first search space set group (SSSG), configuration information regarding a second SSSG, one or more groups of configuration information regarding discontinuous reception (DRX) for one or more serving cells in one or more DRX groups, or configuration information of applying SSSG associated with DRX operation of the UE;
• and
• starting a monitoring of a physical downlink control channel (PDCCH) transmission according to search space sets within the first SSSG at a first time point for the one or more serving cells within the one or more DRX groups based on the configuration information of applying SSSG.

A method performed by a network node, the method comprising:

• transmitting first configuration information to a user equipment (UE) for one or more serving cells in one or more discontinuous reception (DRX) groups, wherein the first configuration information includes at least one of:
• configuration information regarding a first search space set group (SSSG),
• configuration information regarding a second SSSG,
• one or more groups of configuration information regarding DRX, or
• configuration information of applying SSSG associated with DRX operation of the UE, wherein the configuration information of applying SSSG is used to enable the UE to start monitoring a physical downlink control channel (PDCCH) transmission according to search space sets within the first SSSG at a first time point for the one or more serving cells within the one or more DRX groups.
