Abstract: Embodiments provide methods and devices for data transmission and assignment of uplink control channel resources in an uplink FDD carrier, for enabling a terminal device to provide HARQ feedback for data transmitted in the downlink using carrier aggregation of a downlink FDD carrier and at least one TDD carrier. A method includes associating each downlink subframe in the downlink FDD carrier with an uplink control channel subframe in the uplink FDD carrier, associating each downlink subframe and special subframe in the TDD carrier with an uplink control channel subframe in the uplink FDD carrier, assigning uplink control channel resources in the uplink FDD carrier to the terminal device according to the associations, and transmitting data on said downlink FDD carrier and/or TDD carrier, to be received by the terminal device.

Abstract: A data transmission method and an apparatus are provided. In this solution, one contention resource group may be divided into a plurality of terminal device groups, and terminal devices with a same DMRS may exist in two different terminal device groups. Even when terminal devices with a same DMRS exist in two different terminal device groups, interference can still be avoided. Therefore, according to embodiments of the present invention, a quantity of connected terminal devices in one contention resource group is increased while good communication quality is obtained.

Abstract: The present invention relates to the field of mobile communications technologies, and in particular, to a method for sending and receiving information. The user equipment in embodiments of the present invention may determine a frame structure of a serving cell, where in addition to an uplink subframe and a downlink subframe, the frame structure in the embodiments of the present invention further includes a first subframe, and the first subframe includes a first symbol used for downlink transmission, a first GP, and a second symbol used for uplink transmission. More symbols used for downlink transmission and more symbols used for uplink transmission than those in a frame structure in the prior art are introduced by introducing the first subframe, thereby improving downlink transmission and effectively reducing a value of k, that is, reducing a service delay in feeding back a HARQ-ACK.
