The UE further includes a processor configured to configure the transceiver to operate in a first state associated with a reception of a first DCI format in a first search space set in response to an AR reception outcome, and to operate in a second state associated with a reception of a second DCI format in a second search space set. A BS includes a transceiver configured to transmit an AR via a DCI format in a PDCCH. The BS includes a processor configured to configure the transceiver to operate in a first state associated with a transmission of a first DCI format in a first search space set, and to operate in a second state associated with a transmission of a second DCI format in a second search space set.

Abstract: Apparatuses and methods for dynamic adaptation on periodic or semi-persistent uplink transmissions are provided. A method of user equipment (UE) in a wireless communication system includes receiving a set of configurations from a higher layer, identifying, from the set of configurations, a first set of configurations indicating resources for a periodic or semi-persistent uplink transmission, and identifying, from the set of configurations, a second set of configurations for a physical downlink control channel (PDCCH) including a downlink control information (DCI) format, wherein the DCI format includes adaptation information. The method further includes performing the periodic or semi-persistent uplink transmission based on the first set of configurations, receiving the PDCCH including the DCI format based on the second set of configurations, identifying, based on the adaptation information, a third set of configurations indicating the resources for the periodic or semi-persistent uplink transmission, and performing the periodic or semi-persistent uplink transmission based on the third set of configurations.

Abstract: A user equipment (UE), a base station (BS), and a method for managing UE operation in C-DRX. The UE includes a transceiver configured to receive configurations for a drx-onDurationTimer, search space sets for reception of a PDCCH, a first set of CSI-RS resources, SS/PBCH blocks, and a PUCCH resources; and the PDCCH that provides a DCI format including a field indicating whether or not to start the drx-onDurationTimer. A processor is configured to determine an indication by the field to not start the drx-onDurationTimer, and determine reception occasions for the first set of CSI-RS resources during the ON duration. The transceiver is configured to receive the first set of CSI-RS resources or the SS/PBCH blocks during at least one of the reception occasions. The processor is also configured to determine a CSI report based on a reception occasion, which can be transmitted using the PUCCH resource during the ON duration.
