Abstract: A method includes receiving a higher-layer signal from a base station, wherein the higher-layer signal enables the use of 2-stage DCI based cross-carrier scheduling and provides mapping between a scheduling serving cell and one or more scheduled serving cells; receiving a first-stage DCI carried in a PDCCH in a slot in the scheduling serving cell, wherein the first-stage DCI provides the information related to the corresponding second-stage DCI; receiving a second-stage DCI corresponding to the first-stage DCI in a specific set of resource elements in the same slot in the same scheduling cell as the first-stage DCI-based on the information provided in the first-stage DCI, wherein the second-stage DCI provides scheduling information for the scheduled serving cells; and performing data reception or transmission over the scheduled serving cells based on the received 2-stage DCI.

Abstract: Various solutions for network power saving with respect to user equipment and network apparatus in mobile communications are described. An apparatus may receive a power saving indication. The apparatus may obtain power saving information according to the power saving indication. The power saving indication may comprise at least one of a discontinuous reception (DRX) switch indicator for switching between a user equipment (UE)-specific-DRX (U-DRX) and a group-specific-DRX (G-DRX), an energy saving mode (EMS) indication, a list of synchronization signal block (SSB) or channel state information-reference signal (CSI-RS) resources, and a set of transmission configuration indication (TCI)I states or RS resource indexes.

Abstract: A method includes receiving a higher-layer signal from a base station, wherein the higher-layer signal enables the use of 2-stage DCI based cross-carrier scheduling and provides mapping between a scheduling serving cell and one or more scheduled serving cells; receiving a first-stage DCI carried in a PDCCH in a designated time interval in the scheduling serving cell, wherein the first-stage DCI provides the information related to the corresponding second-stage DCI; receiving a second-stage DCI corresponding to the first-stage DCI in a specific set of resource elements in the same designated time interval in the same scheduling cell as the first-stage DCI-based on the information provided in the first-stage DCI, wherein the second-stage DCI provides scheduling information for the scheduled serving cells; and performing data reception or transmission over the scheduled serving cells based on the received 2-stage DCI.

Abstract: A method includes receiving a first higher-layer signal from a base station, wherein the first higher-layer signal enables the use of single PDCCH scheduling PDSCH(s) in two or more serving cells; receiving a second higher-layer signal from the base station, wherein the second higher-layer signal enables the use of cross-carrier HARQ management within the serving cells; receiving DCI in one of the serving cells to obtain the scheduling information of PDSCH(s) in the serving cells; receiving the scheduled PDSCH(s) in the serving cells based on the received DCI to obtain downlink transport blocks carried in the scheduled PDSCH(s); and sending downlink transport blocks to a HARQ entity of the serving cell indicated in the DCI carried in a PDCCH for HARQ management based on a HARQ process number indicated in the DCI carried in the PDCCH.
