    摘要: A plurality of substantially static input parameters are provided, and a plurality of signalled input parameters are also provided. From the substantially static input parameters and the plurality of signaled input parameters, an output parameter is determined that is indicative of a number of control symbols per transmission time interval for an amount of control signaling bits. The output parameter relates to a modulation and coding scheme for an uplink.
