Abstract: A method of a user equipment (UE) in a wireless communication network and a UE are provided. The method includes receiving, from the network, at least one downlink (DL) transmission, determining, by the UE, channel resource information reference signal (CSI-RS) occasions in the at least one DL transmission, determining, by the UE, whether a power of each of the CSI-RS occasions is the same, and averaging, by the UE, corresponding measurements when the power of each of the CSI-RS occasions is determined to be the same.

Abstract: A method for performing PDCCH monitoring of component carriers (CCs) in a carrier aggregation scheme that aggregates a first CC and a second CC. In some embodiments, the method includes: calculating a first monitoring occasion start time for a monitoring occasion of the first CC, wherein the first monitoring occasion start time is expressed as a first symbol-index value; calculating a second monitoring occasion start time for a monitoring occasion of the second CC, wherein the second monitoring occasion start time is expressed as a second symbol-index value; and generating a schedule for the monitoring occasion of the first CC and the monitoring occasion of the second CC based on an ascending order of the first monitoring occasion start time and the second monitoring occasion start time.

Abstract: A method for monitoring capability reporting. In some embodiments, the method includes: receiving, by a network, from a user equipment (UE), a physical downlink control channel (PDCCH) monitoring capability, the PDCCH monitoring capability including: a span pattern requirement specifying one or more restrictions on lengths and separations, and a minimum time separation requirement, the minimum time separation requirement specifying a minimum time separation between downlink control informations (DCIs). The method may further include generating, by the network, in response to the PDCCH monitoring capability, a first monitoring occasion (MO) pattern.
