USER EQUIPMENT AND METHODS FOR CSI MEASUREMENTS WITH REDUCED BANDWIDTH SUPPORT

摘要

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.

1. User equipment (UE) comprising:
transceiver circuitry configured to communicate with an evolved Node-B (eNB); and processing circuitry configured to:
provide reduced bandwidth support of at most six physical resource blocks;configure the transceiver to receive a resource assignment on which to take measurements indicating a narrowband region comprising a reduced bandwidth that is supported by the UE and free from subbands outside of the narrowband region;configure the transceiver to take measurements of downlink transmissions using the assigned resources, the measurements limited to subbands included within the narrowband region;calculate Channel State Information (CSI) based on the measurements; andreport a region-specific wideband CSI that includes at least a region-specific wideband Channel Quality Indicator (CQI) to the eNB.
