Abstract: Embodiments of the present disclosure relate to the field of communications technologies, and provide an information transmission method and apparatus, to flexibly set a quantity of subframes in subframe aggregation and a redundancy version based on a channel condition. The method includes: sending, by a first device, downlink control information to a second device, where the downlink control information includes subframe aggregation information, and the subframe aggregation information is used by the first device to indicate, to the second device, a quantity of subframes used in subframe aggregation and/or a redundancy version corresponding to at least one of subframes used in subframe aggregation; and receiving, by the first device, uplink information sent by the second device according to the downlink control information. The embodiments of the present disclosure are used for subframe aggregation.

Abstract: Embodiments of the present invention disclose a method and a device for detecting and transmitting information. The method includes: obtaining, by a UE, at least one type of configuration information of an antenna port occupied by a D-PDCCH, which is configured on a base station side; determining, by the UE, a search space of the D-PDCCH; and detecting, by the UE, the D-PDCCH in the search space according to the antenna port configuration information. With the embodiments of the present invention, the UE can detect the D-PDCCH, and therefore data transmission is ensured. Furthermore, a blind detection of a PDCCH by the UE based on time-frequency resources in an existing system is extended to a spatial dimension, that is, an antenna port, thereby increasing the efficiency of resource utilization, so that the D-PDCCH can be detected in the spatial dimension.

Abstract: The present disclosure relates to a method and a device for sending and receiving information. The method includes: determining a frame structure of a serving cell, where a radio frame corresponding to the frame structure includes at least one first special subframe, remaining subframes are downlink subframes, and the first special subframe includes symbols used for uplink transmission and downlink transmission, and a GP; and sending and receiving information in the serving cell based on the frame structure. In the technical solution, because the radio frame structure includes the first special subframe, when spectrum resources are maximally applied to downlink data service transmission, not only performance of massive MIMO is improved, but also the serving cell is enabled to work independently.

Abstract: A terminal device determines a resource of a physical uplink control channel. The physical uplink control channel carries a first encoded bit sequence and a second encoded bit sequence, the first encoded bit sequence is corresponding to first uplink control information, and the second encoded bit sequence is corresponding to second uplink control information. The resource for the physical uplink control channel includes N orthogonal frequency division multiplexing (OFDM) symbol sets. The first encoded bit sequence is carried in an OFDM symbol included in j OFDM symbol sets, the j OFDM symbol sets are a part of or all of of the N OFDM symbol sets, where j is a positive integer less than or equal to N. The terminal device sends, on the resource for the physical uplink control channel, a signal that is generated based on the first uplink control information and the second uplink control information.

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: 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.
