    Abstract: Systems, methods, apparatuses, and computer program products for multiport phase tracking reference signal in radio communication. A method may include receiving a radio resource control signaling and/or scheduling information from a network element. The method may also include determining a phase tracking reference signal configuration based on the radio resource control signaling and/or scheduling information. The method may further include carrying out a multiport radio reception or transmission with the network element according to the determined phase tracking reference signal configuration.

    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 a first embodiment, a method may include receiving, by a user equipment, a first physical downlink control channel (PDCCH) configuration from a network entity. The method may further include detecting, by the user equipment, at least one PDCCH based on the first PDCCH configuration. The method may further include transmitting and/or receiving, by the user equipment, at least one signal based on the at least one detected PDCCH.
