Abstract: Techniques are described to feedback hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook. For example, a base station can send HARQ-ACK codebook information to a user equipment, schedule retransmission, and transmit a downlink feedback information (DFI) if the user equipment transmits a code block group (CBG) based autonomous transmission. Techniques are also described for a user equipment to improve the feedback HARQ-ACK efficiency for downlink physical downlink shared channel (PDSCH) transmission.

Abstract: Techniques are described for configuring resources for remote interference mitigation (RIM). An example method includes configuring a first sequence for a reference signal (RS) in response to determining that the RS includes information indicative of a first type of status information. The method also includes configuring a second sequence for the RS in response to determining that the RS includes information indicative of a second type of status information, where the RS is transmitted in response to determining an interference and based on the configured first sequence or second sequence.

Abstract: Method, systems and devices for identifying and mitigating remote interference, e.g. a downlink transmission from a remote network device interfering with uplink transmissions of another network device, are described. One example method for identifying remote interference includes determining that an interference type is a remote interference, and transmitting, in response to the determining, a reference signal indicative of a resource that was affected by the remote interference. Another example method for identifying remote interference includes detecting a reference signal in a frame, and determining a resource that was affected by a remote interference based on a position of the reference signal in the frame.

Abstract: The present disclosure provides a data scheduling and transmission method, apparatus and system. The data scheduling method includes: configuring scheduling information according to a predetermined unlicensed-uplink-subframe scheduling mode, where the scheduling information is used for instructing a terminal to transmit uplink data on an unlicensed frequency spectrum; and receiving, according to the scheduling information, the uplink data sent by the terminal. This solves the problem of a reduced uplink data transmission efficiency due to a lack of a technology for reducing signaling overheads and improving an uplink transmission rate on an unlicensed frequency spectrum in the related art, thereby achieving effects of reducing the signaling overheads and improving the uplink transmission rate on the unlicensed frequency spectrum.
