A user terminal is disclosed including a first decoding section that decodes a downlink signal for another user terminal from downlink signals for a plurality of user terminals that are non-orthogonal multiplexed over a given radio resource. The user terminal includes a first judgement section that judges whether or not the downlink signal for the other user terminal has been successfully received, based on a decoding result in the first decoding section. The user terminal further includes an interference cancellation section that cancels the decoded downlink signal for the other user terminal from the downlink signals for the plurality of user terminals. The user terminal also includes a second decoding section that decodes a downlink signal for the user terminal, from the downlink signals for the plurality of user terminals, from which the downlink signal for the other user terminal has been canceled in the interference cancellation section.

Some aspects of the disclosure provide for wireless communication systems in which scheduling information is transmitted to a scheduled entity to schedule transmission of uplink feedback control information by the scheduled entity. The feedback control information may be transmitted in short uplink control bursts or long uplink bursts. Selection between short uplink control bursts and long uplink bursts may be based on power headroom at the scheduled entity, interference in the short uplink control burst or the long uplink burst, loading of the short uplink control burst or the long uplink burst or processing capability of the scheduled entity.

Apparatuses, computer readable media, and methods for control field for null data packet feedback report trigger are disclosed. A station is disclosed, the station comprising processing circuitry configured to: decode a media access control (MAC) protocol data unit (MPDU) comprising an A-control field of type null data packet (NDP) feedback report poll comprising a feedback type field and an indication of a resource unit (RU). The processing circuitry further configured to determine whether the station is scheduled to respond to the A-control field of type NDP feedback report poll, and if the station is scheduled to respond to the A-control field of type NDP feedback report poll, configure the station to transmit a response to a feedback type indicated by the value of the feedback type field on the RU. Apparatuses, computer readable media, and methods for short block acknowledgment with NDP are disclosed.

According to one embodiment, a wireless communication device includes: a communicator and controlling circuitry. The communicator is configured to simultaneously communicate a first frame and a second frame, and after the first frame and the second frame are communicated, communicate a third frame indicating acknowledgement of the first frame and a fourth frame indicating acknowledgement of the second frame. The controlling circuitry is configured to control to prevent the third frame and the fourth frame from being simultaneously communicated.

An on-board method for the end-to-end transparent transport of data packets is implemented by a telecommunications system comprising a first, sending station, a second, receiving station, a first, sending satellite, connected directly to the first station, and a second, receiving satellite, connected directly to the second station, the first satellite and second satellite being interconnected via a spaceborne network. The transport method comprises steps allowing an end-to-end transparent adaptive control loop for the adaptive control of the modulation and of the coding of the access links between the first station and the first satellite and between the second station and the second satellite to be implemented.
