  • Publication number: 20150264594
    Abstract: Methods, apparatuses, and systems are described related to interference averaging to generate feedback information and interference averaging to demodulate receives signals. In embodiments, an evolved Node B (eNB) may transmit interference averaging information to a user equipment (UE) including a time domain averaging indicator indicating a time domain averaging window to be used by the UE for averaging interference measurements in a time domain or a frequency domain averaging indicator to indicate a frequency domain averaging window to be used by the UE for averaging interference measurements in a frequency domain. Additionally, or alternatively, the eNB may transmit an interference resource group (IRG) indicator to the UE to indicate an IRG over which the UE is to perform interference averaging to facilitate demodulation of signals received by the UE from the eNB.

  • Patent number: 9106386
    Abstract: Coordinated Multipoint (CoMP) involves multiple transmission points or cells coordinating their individual transmissions so that a target user equipment (LTE) experiences enhanced signal reception and/or reduced interference. In order to optimally implement downlink CoMP, a serving cell needs to obtain channel state information (CSI) for the downlink channels from the multiple transmission points to the UE. This disclosure deals with radio resource control (RRC) signaling for configuring the UE to obtain and report CSI for those downlink channels.

  • Patent number: 9094855
    Abstract: Technology for enabling radio resource management (RRM) measurements in coordinated multi-point (CoMP) transmission and reception is disclosed. One method comprises sending, from an evolved node B (eNB) to a user equipment (UE), an information element (IE) containing a list of measurement objects that define configurations of channel state information reference signal (CSI-RS) based RRM measurements. The eNB can analyze the CSI-RS based RRM measurements in a CoMP Resource Management (CRM) Set, wherein each CSI-RS based RRM measurement corresponds to a transmission point in a set of transmission points which may be used for downlink transmissions to the UE. The eNB can select a CoMP Measurement Set based on the CSI-RS based RRM measurements reported by the UE, comprising at least one of the set of transmission points for which fast channel state information (CSI) feedback will be reported to the eNB from the UE.
