Abstract: Aspects of the disclosure provide a method and an apparatus for transitioning one or a plurality of activated secondary cells (SCells) between a dormancy behavior and an active behavior. For example, the apparatus can include receiving circuitry and processing circuitry. The receiving circuitry can be configured to receive a configuration indicating a number of SCell groups each including at least one of the SCells, and an indication of at least one of the SCell groups to be transitioned between the dormancy behavior and the active behavior. The processing circuitry can be configured to transition the at least one SCell of the at least one SCell group between the dormancy behavior and the active behavior.

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, applied to a UE, to mitigate interference for coexistence of OFDM-based radio access technologies, wherein the method includes receiving a dedicated RRC signal providing LTE CRS configuration information of neighboring LTE cells in one or more LTE carriers and providing the corresponding frequency location and bandwidth of the LTE carriers for an NR serving cell, wherein NR and LTE coexist in the same spectrum; determining the LTE CRS configuration and the corresponding frequency location of LTE CRS based on the received dedicated RRC signal; and performing LTE CRS interference suppression or cancellation in NR downlink (DL) transmission.

Abstract: A method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives, from a base station, one or more BWP configurations for configuring a plurality of BWPs at the UE. The respective one or more BWP parameters of a set of BWP parameters define each respective BWP of the plurality of BWPs. The UE sends a capability indication indicating that the UE is capable of resetting values of one or more parameters of the set of BWP parameters. The UE sends a subset indication indicating that the UE is capable of resetting values of one or more parameters of a subset of BWP parameters from the set of BWP parameters.

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.
