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.

Dependent claims

A user equipment (UE) comprising:

a transceiver configured to:
receive configurations for (i) a drx-onDurationTimer corresponding to an ON duration of a discontinuous reception (DRX) cycle, (ii) search space sets for reception of a physical downlink control channel (PDCCH) prior to the ON duration of the DRX cycle, (iii) a first set of channel state information reference signal (CSI-RS) resources, (iv) synchronization signals/physical broadcast channel (SS/PBCH) blocks, and (v) a physical uplink control channel (PUCCH) resource, and
receive the PDCCH, wherein the PDCCH provides a DCI format that includes a field indicating whether or not to start the drx-onDurationTimer;
and
a processor operably connected to the transceiver, the processor 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,
wherein the transceiver is further configured to receive the first set of CSI-RS resources or the SS/PBCH blocks during at least one of the reception occasions,
wherein the processor is further configured to determine a CSI report based on a reception occasion from the at least one of the reception occasions, and
wherein the transceiver is further configured to transmit a PUCCH with the CSI report using the PUCCH resource during the ON duration.
