    摘要: Downlink interference alignment schemes are described which provide, among other things, channel state information (CSI) from the UEs using a constant amplitude codebook. By providing only phase information associated the UEs' channel states, instead of both amplitude and phase information, fewer bits can be used to inform the BSs of the UEs effective channels, thereby reducing the bandwidth requirements associated with the transmission of CSI by UEs for downlink interference alignment purposes. According to other embodiments, feedback information can be used to perform user selection scheduling and rate balancing.

    摘要: The auto-correlation properties of a reference signal or pilot pattern, such as a position reference signal (PRS) in a Long Term Evolution communication system, is improved by modifying the currently specified PRS patterns, and/or by PRS pattern shaping. Pattern shaping can result in creation of virtual PRS patterns, for example, by controlling the PRS transmitted or received power used by the correlator. PRS power shaping can be implemented differently according to the location where the PRS power is calculated, e.g., in a network node or in a user equipment.

    摘要: In a mobile communication system, receiving changed information for a service of interest in a next modification period comprises determining in a current modification period whether an alarm bit whose assertion indicates upcoming changed information is unambiguously associated with the service of interest or whether the alarm bit is associated with the service of interest and one or more services that are not of interest. Mappings of all services to alarm bits are analyzed in the present and possibly in one or more upcoming frames during the current modification period and applied in embodiments to reduce the ambiguity and therefore the risk of false indications of changed data for the service of interest.
