Abstract: Methods, systems, and devices for wireless communications are described, in which a communication device (e.g., a user equipment (UE), a network entity) may perform carrier aggregation, and cross-carrier scheduling provides that a first carrier may provide scheduling information for one or more other carriers, in which the one or more other carriers may have different discontinuous reception (DRX) configurations than the first carrier. One or more DRX-related timers of different DRX groups may be started or restarted based on a control information reception on the first carrier, or on a different carrier of a different DRX group. Additionally, or alternatively, control information transmissions on the first carrier may be provided based on one or more DRX-related timers that are associated with the first carrier, or that are associated with a carrier of another DRX group than the DRX group of the first carrier, or any combinations thereof.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support dynamic uplink control channel grouping. For example, a user equipment (UE) may receive control signaling indicating multiple uplink control channel groups for the UE, where each uplink control channel group of the multiple uplink control channel groups is associated with a different set of uplink control channel resources. Additionally, the UE may select an uplink control channel group for a component carrier (CC) associated with the UE, where the uplink control channel group is selected in accordance with a detected trigger at the UE. Further, the UE may transmit uplink control information for the CC in accordance with the selected uplink control channel group.

Abstract: Systems, methods, and devices for secondary cell activation using temporary reference signals are provided. In one aspect, a method of wireless communication performed by a user equipment (UE), includes receiving, from a base station (BS) via a first cell, an activation command to activate a second cell different from the first cell, and receiving, from the BS via the second cell during an activation period, a first reference signal different from a synchronization signal block (SSB). The method further includes performing a measurement of the first reference signal, and operating in the second cell based on the measurement. In some aspects, using reference signals different from SSBs may reduce the delay associated with activating the secondary cell.

Abstract: A UE may enter a dormant state, e.g., for power savings. The systems, methods, and apparatus described herein may provide ways for the UE to transition between an active state and a dormant state, as well as UE behavior in a dormant state. The apparatus may be a UE configured to receive downlink control information (DCI) comprising an indication of a bandwidth part (BWP) switch for a secondary cell to a dormant BWP and transition the secondary cell from an active state to a dormant state based on the indication of the BWP switch of the secondary cell to a dormant BWP.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a channel state information reference signal for a downlink cell associated with a first physical uplink control channel (PUCCH) group. The UE may report measurement information associated with channel state information reference signal using an uplink cell of a second PUCCH group associated with the first PUCCH group. Numerous other aspects are described.

Abstract: The present disclosure describes various aspects of the implementation and design of Physical Downlink Control Channel (PDCCH) in 5G new radio (NR) applications. Aspects include methods, apparatuses, and computer-readable medium for one or more of multiple PDCCH search spaces, control resource block (CRB), irregular multiple slots or mini-slots grants, or fast control channel signaling for grant-free uplink (UL). For example, different scheduling entities can each have one or two search spaces defined (e.g., common and/or user equipment (UE)-centric search spaces). Also, CRBs can be used as units for PDCCH transmission instead of resource element groups/control channel elements (REGs/CCEs). In addition, irregularities in time domain, frequency domain, or both can be introduced in the granting of resource blocks (RBs) over multiple slots or mini-slots. Moreover, signaling can be used to indicate to a UE configured for grant-free UL the portion of the pool of resources available for grant-free UL.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for radio link monitoring with BWPs and interference measurements using communications systems operating according to new radio (NR) technologies. Certain aspects provide a method for wireless communication. The method generally includes determining one or more bandwidth parts (BWPs) for radio link monitoring (RLM) based on one or more signals; and configuring a user equipment (UE) to monitor the one or more signals on the one or more BWPs within a maximum channel bandwidth.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a modulation and coding scheme (MCS) for an uplink communication of the UE; identify a set of beta values for uplink control information of the uplink communication according to a mapping between the set of beta values and the MCS, wherein the set of beta values is for determination of a number of resource elements or modulation symbols for the uplink control information; and transmit the uplink control information based at least in part on the set of beta values. Numerous other aspects are provided.
