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.

Abstract: A method of UE power profile adaptation to traffic and UE power consumption characteristics based on power profile is proposed. In one preferred embodiment, hybrid of bandwidth part (BWP) and power profile is proposed. UE is configured with multiple BWPs and each BWP includes a set of power profiles. Two types of adaptation triggering can be used, a first type of trigger is based on power saving signals sent from the network, and the second type of trigger is based on timers. When the traffic characteristic for UE changes, the network can send a power saving signal to UE to trigger power profile adaptation, e.g., BWP+power profile switching. When traffic has been digested and becomes sporadic, then power profile adaptation can be triggered based on timers, e.g., a timer for BWP adaptation and another timer for power profile adaptation.

Abstract: Various solutions with respect to cross-slot scheduling for power saving in mobile communications are described. An apparatus receives, from a wireless network, a control signaling. According to the control signaling, the apparatus changes an aspect of a power profile of at least one bandwidth part (BWP) of a plurality of BWPs without causing data interruption regarding data transmission or reception by the apparatus. The apparatus also receives, from the wireless network, an indication. According to the indication, the apparatus adapts a new minimum applicable value of at least one of a downlink scheduling offset (K0), an uplink scheduling offset (K2), and an aperiodic channel state information reference signal (CSI-RS) triggering offset for an active DL BWP or an active UL BWP of the plurality of BWPs.

Abstract: A method of dynamically adapt to a minimum applicable scheduling offset value for a UE operated with bandwidth part (BWP) and cross-slot scheduling in a mobile communication network is proposed. At higher layer (L2 RRC layer), the UE receives RRC configuration for a set of minimum applicable scheduling offset values (K0/K2) for downlink/uplink cross-slot scheduling. At lower layer (L1 physical layer), the UE dynamically determines an active minimum K0/K2 value for an active DL BWP or UL BWP based on 1) a one-bit DCI indicator over PDCCH; or based on 2) an active BWP change due to timeout.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE attempts to detect a trigger event. The UE determines values of a first set of power configuration parameters when the trigger event is detected, wherein a change in a value of each power configuration parameter in the first set of power configuration parameters affects power consumption of the first UE. The UE transmits or receives signals in accordance with the values of the first set of power configuration parameters.
