  • Publication number: 20210195632
    Abstract: Techniques (e.g., method, apparatuses, etc.) for permitting communications, e.g., optical communications are described. In one example, a first communication apparatus for the communication with a second communication device may obtain a channel state information from the reception of one or more reference signals and/or beacon signals from one or more frontends of the second apparatus. The first communication apparatus may transform the channel state information from a frequency domain to a time domain, to obtain a time domain channel state information. The first communication apparatus may encode the time domain channel state information. The first communication apparatus may transmit the time domain channel state information to one or more frontends. The first communication apparatus may transmit channel information for association and updated channel information for network coordination in a contention access period and collision-free period, CFP, respectively.

  • Patent number: 9065715
    Abstract: A method for operating a radio communication system involves the use of OFDM and involves a first sending station modulating a first OFDM symbol onto a first carrier frequency and sending the first OFDM symbol to a first receiving station via a first transmission channel using an air interface. The first sending station changes the first carrier frequency during a time used for sending the first OFDM symbol, the change in the first carrier frequency being made independently of a change in transmission characteristics of the first transmission channel over time. A fast frequency hopping system is disclosed.

  • Patent number: 8995917
    Abstract: A method detects a first baseband signal sent by a first sending station via an air interface to a first radio station of a radio communications system. A first receive signal, which contains the first baseband signal superposed with at least a second baseband signal sent by a second sending station to a second radio station, is received by the first radio station. The first radio station uses at least a second receive signal received by the second radio station for detection of the first baseband signal.
