Abstract: The application discloses a physical uplink shared channel data transmission method and device. The method comprises: a terminal adjusts or schedules, according to detected downlink control channel data utilizing an uplink DCI format and/or PHICH data in a subframe n, PUSCH data to be transmitted in a special subframe (n+k), wherein k is a predefined value. A base station transmits the downlink control channel data utilizing the uplink DCI format and/or the PHICH data in the subframe n, to adjust or schedule the terminal to transmit the PUSCH data in the special subframe (n+k), wherein k is a predefined value. The application provides a schedule timing definition for transmitting PUSCH data in a special subframe, thereby ensuring normal transmission of the PUSCH data in the special subframe.

Abstract: Embodiments of the present application relate to the technical field of wireless communications, and in particular, to a method, a device and a system for transmitting a data packet, which are used to resolve the problem existing in the prior art that an LTE network structure causes a signaling burden on a backhaul between a radio access network and a core network and causes a transmission delay on the backhaul. In the embodiments of the present application, a control point sends a data packet that is from at least one base station to an access network gateway or a core network gateway; and a data packet that is from the access network gateway or the core network gateway is sent to the at least one base station, the control point being a connection control point of a terminal and a mobility control point of the terminal. In the embodiments of the present invention, a control plane signaling process of a core network of a new network architecture is greatly simplified; therefore, the control delay and traffic pressure on a Backhaul between an access network and a core network are reduced. Under the control of a control point, a transmission mode is flexibly selected at an access network side, so that requirements of different services on aspects of the delay and reliability can be met.
