Abstract: A generation node B (gNB) configured for aperiodic channel state information reference signal (CSI-RS) triggering and transmission may encode signalling for transmission to a user equipment (UE). The signalling to indicate an aperiodic Triggering Offset (aperiodicTriggeringOffset). The aperiodic Triggering Offset may comprise a slot offset. The gNB may encode a downlink control information (DCI) for transmission that may trigger transmission of a CSI-RS in one or more aperiodic CSI-RS resource set(s) (i.e., in one or more slots (n)). The DCI triggers transmission of the aperiodic CSI-RS within a triggered slot with the slot offset (i.e., the aperiodicTriggeringOffset). The gNB may transmit the CSI-RS in resource elements of the triggered slot in accordance with the slot offset, when CSI-RS resources are available in the slot at the slot offset. The gNB may postpone transmission of the aperiodically triggered CSI-RS to a first available downlink slot when the CSI-RS resources are not available in the triggered slot at the slot offset.

Abstract: An enhanced NodeB (eNB), user equipment (UE) and method of Channel State Information (CSI) measurement and reporting using reduced bandwidth are generally described herein. The UE is preconfigured with a resource configuration information or the configuration information is transmitted to the UE from the eNB. The configuration information indicates a narrowband region on which to monitor for and receive physical downlink control and data channels and perform measurements for CSI computation. The region has a reduced bandwidth that is supported by the UE and is free from subbands outside of the region. The UE takes measurements of downlink transmissions using the assigned resources. The measurements are limited to subbands included within the region. The UE calculates the CSI based on an unrestricted time interval within subframes of the region and a restricted frequency interval free from physical resource blocks outside the region. The UE reports a region-specific wideband CSI that includes at least a region-specific wideband Channel Quality Indicator to the eNB.

Abstract: Wireless device, method, and computer readable media are disclosed for determining which channel status information (CSI) report of a user equipment (UE) to drop from a physical uplink control channel (PUCCH) packet. The method may include determining that a first CSI report and a second CSI report are to be sent in the PUCCH, where the first CSI report has a first reporting type and a first CSI sub-frame set, and the second CSI report has a second reporting type and a second CSI sub-frame set. The method may include determining to drop the first CSI report if the first CSI sub-frame set has a second lower priority than the second CSI sub-frame set. The determination to drop may be further based on a CSI processor index, serving cell index, and the CSI report priority.
