Publication number: 20220190891Abstract: Systems and methods for decoding a transmission are provided. In some embodiments, a method performed by a wireless device comprises determining a plurality of Machine-Type Communications (MTC) Physical Downlink Control Channel (MPDCCH) transmission candidates to monitor. For at least one candidate of the plurality of MPDCCH transmission candidates, the method includes determining whether the candidate belongs to a first group of candidates or a second group of candidates. If the candidate belongs to the first group of candidates, the method includes attempting to decode the MPDCCH transmission using a Channel State Information (CSI)-based precoding scheme. If the candidate belongs to the second group of candidates, the method includes attempting to decode the MPDCCH transmission using a predetermined precoding scheme. This may allow a more robust precoding technique and can be considered as technique with a fallback solution for the cases in which the CSI is either missed or not reliable.Type: ApplicationFiled: January 31, 2020Publication date: June 16, 2022Inventors: Saeedeh Moloudi, Anders Wallén
