Abstract: A method and device for determining the initial positions of a downlink data channel are provided. The method includes: a base station transmits to a terminal a generated indication signaling, and the terminal determines, on the basis of the received indication signaling, the time domain initial positions of the downlink data channel in L downlink TTIs. With the method, when the downlink control channel only appears in a part of the positions in a frequency domain or does not appear at all, and when the downlink control channel does not occupy the complete downlink control area in the time domain or the resources occupied by the downlink control channel in the time domain are variable, the base station can still accurately notify the terminal the time domain initial positions of the downlink data channel.

Abstract: Disclosed in the present application are a method and device for feeding back downlink data. When a processing duration of an UE is shortened, feedback timing information for feeding back downlink data may be adaptively changed. The method comprises: determining a processing capability of an UE, the processing capability referring to a processing duration that the UE takes to process the received downlink data to determine whether said downlink data needs to be retransmitted; according to the determined processing capability, determining the feedback timing information of the UE feeding back the downlink data.

Abstract: Disclosed are an uplink and downlink transmission resource allocation method and device. In this application, a first channel is transmitted on a specified time-frequency resource within a first channel transmitting period according to the first channel transmitting period. The first channel is at least used for notifying allocation information of an uplink transmission resource and a downlink transmission resource within the first channel transmitting period or an effective time period of the first channel, so that dynamic partitioning and notification of the uplink transmission resource and the downlink transmission resource are achieved.

Abstract: The present invention discloses a transmission method and apparatus for feedback information of uplink transmission. The method comprises: a terminal transmitting a physical uplink shared channel (PUSCH) in a special sub-frame m, where m is an integer; the terminal detecting, subsequent to the special frame m, in a sub-frame comprising downlink transmission resources or in a sub-frame m+k, a downlink control channel using an uplink/downlink control information (DCI) format, where k is a positive integer; and the terminal determining, according to the downlink control channel, whether to again transmit the PUSCH transmitted in the special sub-frame m. accordingly, the present invention provides a transmission solution that transmits PUSCH feedback information in a special sub frame, ensuring that the PUSCH transmitted in the special sub frame can normally obtain ACK/NACK feedback information.
