  • Patent number: 10756849
    Abstract: A system and method for efficiently transporting data in a computing system are contemplated. In various embodiments, a computing system includes a source, a destination and multiple lanes between them for transporting data. Multiple receivers in the destination has a respective termination resistor connected to a single integrating capacitor, which provides a reference voltage to the multiple receivers. The receivers reconstruct the received data by comparing the corresponding input signals to the reference voltage. The source includes a table storing code words. The source maps a generated data word to a code word, which is sent to the destination. The destination maps the received code word to the data word. The values of the code words are selected to maintain a nearly same number of Boolean ones on the multiple lanes over time as a number of Boolean zeroes.

  • Patent number: 10673591
    Abstract: Pilot tones are included within symbols (e.g., orthogonal frequency division multiplexing (OFDM) symbols) transmitted between wireless communication devices. The pilot tones occupy fewer than all tone locations in any given symbol, and the pilot tones occupy different respective locations within different symbols. Generally, these traveling pilots are assigned to different respective tone locations in different symbols. In total, the pilot tones did not cover every single tone location within the symbols used to convey information between devices. Considering for example, when pilots occupy fewer than all tone locations, even among multiple symbols, a device may perform interpolation to generate a pilot tone estimate corresponding to a tone location not occupied by pilot tone within any symbol. Also, power or magnitude of the pilot tones themselves may be boosted or amplified relative to power magnitude of other tones within such symbols.

  • Patent number: 10651917
    Abstract: Transmission configuration indication (TCI) states may be used to indicate beam switching for data beams and/or control beams. A total set of TCI states may be divided into subsets of TCI states. TCI states conveyed via downlink control information (DCI) may thus act as beam switching indications depending on which subset a conveyed TCI state resides. A base station may transmit an indication that such DCI based control beam switching is enabled. Based on whether TCI state (e.g., included in DCI) belongs to a first subset of TCI states or a second subset of TCI states, a wireless device (e.g., that receives the DCI) may trigger a beam switching operation. Beam switching operations may include data beam switching or both data beam switching and control beam switching. The UE may then receive a downlink control channel and a downlink data channel based on the triggered beam switching operation.
