  • Patent number: 11489710
    Abstract: A method is used for frequency offset estimation in a wireless communication network that employs time based scheduling of packets. The method is performed by a packet receiver in the wireless communication network. The method includes receiving a packet from a packet transmitter. The packet includes a preamble that is composed of samples of a single orthogonal frequency-division multiplexing symbol. The preamble has a cyclic prefix (CP) defined by a repetition of samples from an end-portion of the preamble and the preamble, except for the CP, is free from any repeated sequence of samples. The method also includes determining a sequence of similarity measure values between the CP of the preamble and the end-portion of the preamble, applying a low-pass filter to the sequence of similarity measure values, resulting in a filtered sequence of similarity measure values, and performing frequency offset estimation on the filtered sequence of similarity measure values.

  • Patent number: 11349550
    Abstract: An integrated terrestrial/non-terrestrial network may allow for enhanced network coverage. However, there are control and management challenges associated with an integrated terrestrial/non-terrestrial network because the network and user equipments (UEs) are no longer confined to only using conventional cellular communication via terrestrial transmit-and-receive points (T-TRPs). One challenge is how to perform beam management. In some embodiments, methods and systems are disclosed in which an indication of angular direction (e.g. beam direction) is provided by the T-TRP. The indication of angular direction may be used by a UE for communicating with a non-terrestrial TRP (NT-TRP), e.g. using beamforming. However, the methods are not limited to integrated terrestrial/non-terrestrial networks or the involvement of NT-TRPs, but apply more generally to indicating angular direction for directional communication.
