  • Patent number: 10999861
    Abstract: Methods, systems, and devices for wireless communications are described for identifying a modulation and coding scheme (MCS) independently of a channel quality indicator (CQI) table that is configured at a user equipment (UE). A rate matching parameter may be determined based on one or more of the MCS or CQI table, which may be used for dimensioning a soft buffer that is used to store received transmissions for decoding. The MCS field may be a six-bit field and may indicate an MCS that exceeds a highest MCS associated with the CQI table. The base station may activate a semi-persistent scheduling (SPS) configuration at the UE through an activation command, and the UE may verify that SPS is activated based on information in a number of different fields of control information which may include the MCS field.

  • Patent number: 10958595
    Abstract: A system includes a cut-through bridge including a plurality of stages within a controller for communication packet transmission to transfer data and one or more control signals successively between the stages. The system also includes a control signal interceptor within the controller operable to intercept control signals between a first stage and a second stage of the cut-through bridge. The control signal interceptor is further operable to generate a forced valid control signal for each of the control signals regardless of an error condition of the control signals. The control signal interceptor outputs the forced valid control signal for each of the control signals to the second stage of the cut-through bridge. The forced valid control signal for each of the control signals is propagated through one or more successive stages of the cut-through bridge to an end stage to prevent an invalid state at the end stage.
