  • METHOD AND APPARATUS FOR DETECTING UNRELIABLE UPLINK CONTROL INFORMATION
    Publication number: 20240114514
    Abstract: A method of operating a network node in a communications network that includes a communication device is provided. The method can include receiving uplink control information, UCI, from the communication device. The method can further include determining whether the UCI is reliable based on a maximum distance and a threshold value.

  • Dynamic downlink power allocation for supporting higher order modulation
    Patent number: 10397878
    Abstract: A method and network entity for enabling higher order modulation (HOM) mode support for HOM capable wireless devices. The method includes determining a legacy mode power offset value for HOM mode capable wireless devices in legacy modulation mode and calculating a power headroom value for sending downlink data to the HOM mode capable wireless devices. When the power headroom value exceeds a threshold value, the HOM mode support for the HOM mode capable wireless devices is enabled using the identified legacy mode power offset value. When the power headroom value does not exceed the threshold value, and a HOM mode power offset value is available, the HOM mode power offset value being less than the legacy modulation mode power offset value, the HOM mode support for the HOM mode capable wireless devices is enabled using the HOM mode power offset value.

  • Method and system for wireless communication channel estimation
    Patent number: 9071473
    Abstract: A method and system for selecting an algorithm for channel estimation in a wireless communication system are disclosed. According a parameter indicative of an accuracy of a channel estimation algorithm is determined. A selection between a first channel estimation algorithm and a second channel estimation algorithm is made based on the determined parameter.
