US 12,120,666 B2 · Cross-carrier scheduling across different DRX groups

Abstract

Apparatuses and methods for cross-carrier scheduling across different discontinuous reception (DRX) groups. A method includes receiving first information for a first and second sets of values for a first set of DRX timers associated with first and second DRX cell groups, respectively; receiving second information, from a first cell, for scheduling on a second cell; and receiving a physical downlink control channel (PDCCH) on the first cell. The first and second DRX cell groups do not have a common cell. The first and second cells are from the first and second DRX cell groups, respectively. The method further includes determining a first DRX Active time for the first DRX cell group based on the first set of values and the PDCCH reception and determining a second DRX Active time for the second DRX cell group based on the second set of values and the PDCCH reception.

A method comprising:

receiving:
first information for:
a first set of values for a first set of discontinuous reception (DRX) timers associated with a first DRX cell group, and
a second set of values for the first set of DRX timers associated with a second DRX cell group, wherein the first DRX cell group and the second DRX cell group do not have a common cell;
second information for scheduling, from a first cell, on a second cell, wherein:
the first cell is from the first DRX cell group, and
the second cell is from the second DRX cell group;
and
a physical downlink control channel (PDCCH) on the first cell, wherein the PDCCH schedules a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH) on the second cell;
receiving the PDSCH or transmitting the PUSCH on the second cell;
and
determining:
a first DRX Active time for the first DRX cell group based on the first set of values and the PDCCH reception, and
a second DRX Active time for the second DRX cell group based on the second set of values and the PDCCH reception.
