Abstract
A method performed by a transmitting station for assisting a receiving station in mitigating effects of a narrowband interference affecting the receiving station in a wireless communications network. The transmitting station determines (503) a likelihood of presence of the narrowband interference. When the likelihood of presence of the narrowband interference exceeds a threshold of the likelihood, the transmitting station sends (505) to the receiving station a recommendation to avoid smoothing of the channel estimates of the receiving station. The recommendation indicates a high likelihood of presence of the narrowband interference.
Claims34
A method performed by a transmitting station for assisting a receiving station in mitigating effects of a narrowband interference affecting the receiving station in a wireless communications network, the method comprising:
- determining a likelihood of a presence of the narrowband interference;
- determining whether the determined likelihood of the presence of the narrowband interference exceeds a threshold;
- and
- as a result of determining that the determined likelihood of the presence of the narrowband interference exceeds the threshold, sending to the receiving station a recommendation to avoid smoothing of the channel estimates of the receiving station, which recommendation indicates a high likelihood of presence of the narrowband interference.
A transmitting station for assisting a receiving station in mitigating effects of a narrowband interference affecting the receiving station in a wireless communications network, which transmitting station is configured to:
- determine a likelihood of presence of the narrowband interference, and
- when the likelihood of presence of the narrowband interference exceeds a threshold of the likelihood, send to the receiving station a recommendation to avoid smoothing of the channel estimates of the receiving station, which recommendation indicates a high likelihood of presence of the narrowband interference.
A method performed by a receiving station for mitigating effects of a narrowband interference affecting the receiving station in a wireless communications network, the method comprising:
- obtaining an indication of a high likelihood of presence of the narrowband interference;
- and
- based on the obtained indication, performing one or more of:
- adjusting a soft information related to a user data bit and avoiding smoothing of the channel estimates of the receiving station based on the indication.
(canceled)
A receiving station for mitigating effects of a narrowband interference affecting the receiving station in a wireless communications network, the receiving station is being configured to:
- obtain an indication of a high likelihood of presence of the narrowband interference, and
- based on the indication, adjust a soft information related to a user data bit and/or avoid smoothing of the channel estimates of the receiving station based on the indication.
