Abstract: Described are methods for dealing with phase noise, e.g., common phase error and/or inter-carrier interference, in communication systems, and apparatuses for the same. A method can include at least: transmitting one or more reference signals (in-band signals within a channel); and mapping the reference signals to radio resources in the channel for transmission of the reference signals. An amount of the radio resources may depend on, e.g., information about a modulation and coding scheme used for transmission. An associated method can include at least: receiving one or more reference signals, and mapping the reference signals to radio resources in the channel for reception of the reference signals; receiving information about a modulation and coding scheme to be used, an amount of the radio resources depending on, e.g., information about the modulation and coding scheme used for reception; and using the reference signals to compensate for phase noise.

Abstract: One embodiment is directed to a method comprising generating at least one symbol of a subframe for control information based on a first subcarrier spacing; generating at least one data symbol of the subframe based on a second subcarrier spacing; and transmitting the subframe comprising the at least one symbol for control information and at least one data symbol. Another embodiment is directed to a method comprising receiving a subframe comprising at least one symbol for control information and at least one data symbol; decoding the at least one symbol for control information based on a first subcarrier spacing; and obtaining from the decoded at least one symbol information regarding a second subcarrier spacing used on the at least one data symbol.

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: Various communication systems may benefit from new slot formats to support dynamic allocation between SC and CP-OFDMA. In accordance with some embodiments, a method may include transmitting, by a network entity, at least one physical downlink slot containing at least one physical downlink shared channel (PDSCH) and at least one physical downlink control channel (PDCCH). The at least one PDCCH is associated with at least one subcarrier waveform without a cyclic prefix (CP). The at least one PDSCH is associated with at least one CP-orthogonal frequency division multiplexing (OFDM) or single carrier (SC) waveform.

Abstract: This document discloses a solution for reducing peak-to-average power ratio in a radio device. According to an aspect, an apparatus includes circuitry configured for performing: acquiring a block of modulated symbols to be transmitted over a radio interface; transforming the block of modulated symbols from a time domain into a frequency domain for sub-carrier mapping; performing a time-domain peak detection procedure on the block of modulated symbols before said transforming; upon detecting at least one peak in the block of modulated symbols during the time-domain peak detection procedure, computing a peak correction signal for the block of modulated symbols and allocating the peak correction signal to one or more sub-carriers dedicated to the peak correction signal in the sub-carrier mapping; and upon detecting no peak in the block of modulated symbols during the time-domain peak detection procedure, omitting said computing and said allocating.
