Abstract: There is provided applying minimum radio frequency performance requirements to uplink transmission, when there are multiple possible multiple sets of minimum radio frequency performance requirements. A network node determines a condition for applying a first set of minimum radio frequency performance requirements or a second set for minimum radio frequency performance requirements by a device for uplink transmissions in a given radio technology. The network node transmits an indication to the device indicating whether the first set or the second set of requirements can be applied for subsequent uplink transmissions.

Abstract: An inter-carrier interference method comprises: receiving one or more OFDM signal comprising plural blocks of OFDM subcarriers of a first type and plural blocks of OFDM subcarriers of a second type, wherein the frequencies of the subcarriers of each block of OFDM subcarriers of the first type are contiguous and wherein the plural blocks of subcarriers of the first type are distributed amongst the plural blocks of subcarriers of the second type; for each of the plural blocks of subcarriers of the first type, estimating inter-carrier interference components; estimating inter-carrier interference components for the subcarriers of the second type using the inter-carrier interference components estimated for the plural blocks of subcarriers of the first type; and compensating for inter-carrier interference in the plural blocks of subcarriers of the second type using the inter-carrier interference components estimated for the sub-carriers of the second type, thereby to generate plural compensated blocks of subcarriers of the second type.

Abstract: According to an aspect, there is provided a waveform processing device. Said waveform processing device comprises means for performing the following. Upon receiving one or more input signals, each of which corresponds to a different subband, the waveform processing device segments each of the one or more input signals to a subband-specific set of parallel signal blocks. Then, the waveform processing device filters each subband-specific set by applying at least a first time window function, a transform-plane window function and a second time window function in this order. Finally, the waveform processing device concatenates filtered signals to an output signal.
