Abstract: The invention relates to a control channel signal for use in a mobile communication system providing at least two different scheduling modes. Further the invention relates to a scheduling unit for generating the control channel signal and a base station comprising the scheduling unit. The invention also relates to the operation of a mobile station and a base station for implementing a scheduling mode using the control channel signal. In order to facilitate the use of different scheduling schemes for user data transmission while avoiding an additional flag for indicating the scheduling mode in the control signaling, the invention proposes the use of code points in existing control channel signal fields. Further, the invention proposes a specific scheduling mode for use in combination with the proposed control channel signal. According to this scheduling mode control channel information is only provided for retransmissions, while initial transmissions are decoded using blind detection.

Abstract: When a base station is capable of using multiple different types of waveforms for a downlink communication to a UE, the UE may waste processing resources attempting to receive and/or process the downlink communication. For example, the UE may cycle through various possible types of waveforms in an attempt to process the downlink communication. Techniques described herein use waveform signaling for downlink communications to notify the UE of a type of waveform being used for a downlink communication, thereby conserving UE resources (e.g., processing resources, memory resources, RF resources, and/or the like) that would otherwise be wasted attempting to process the downlink communication using multiple types of waveforms.

Abstract: Methods and apparatuses are disclosed for providing control and data information in communication systems. A method performed by a user equipment (UE) in a wireless communication system includes identifying first offset information; determining a size of uplink data for the UE; and transmitting, to a base station in the wireless communication system, the uplink data with at least one of acknowledgement/non-acknowledgment (ACK/NACK) information and channel quality indicator (CQI) information on a physical uplink shared channel (PUSCH). A number of ACK/NACK repetition is determined based on the first offset information and the size of the uplink data.

Abstract: The invention relates methods for triggering channel quality feedback for at least one of plural component carriers of a communication system available for downlink transmission. The invention suggests a mechanism for triggering channel quality feedback from a terminal where the downlink control signaling overhead for the selection of component carrier(s) to be reported on is minimized. One aspect of the invention is a new interpretation of a predetermined format for dedicated control information comprising a CQI request flag, which is depending on the status of the CQI request flag. In case the CQI request flag is set at least one further bit of the dedicated control information is interpreted as information indicative of the one or more component carriers available for downlink transmission to the terminal and the terminal is providing channel quality feedback on the channel quality experienced on the indicated component carrier or component carriers.

Abstract: Techniques are disclosed relating to channel quality reporting for full-duplex (FD) wireless communications. In some embodiments an apparatus (e.g., a mobile device) is configured to receive a reference signal in a wireless communication and determine one or more signal quality indicators for FD communications based on a measured SINR of the reference signal and one or more self-interference cancelation levels. The apparatus may determine the one or more self-interference cancelation levels based on the transmit power of signals transmitted by the apparatus and residual power after SIC. The SIC levels may include both analog and digital SIC levels, which may be separately determined. One or more modulation and coding schemes may be determined based on the effective SINR. In some embodiments, multiple effective SINRs are determined for multiple different transmission modulation orders used by the apparatus.
