    Abstract: A downlink transmission method and a corresponding base station and terminal are provided. In some feasible implementations, a base station sends downlink control information to a terminal in a subframe n+k, where the downlink control information includes indication information and a HARQ process identification, the indication information is used to indicate a location of at least one OFDM symbol in data that is sent by the base station to the terminal in a subframe n, the HARQ process identification in the downlink control information is the same as a HARQ process identification in the subframe n, and both n and k are natural numbers; and the base station transmits, in the subframe n+k, at least data that is sent to the terminal and that is on the at least one OFDM symbol that is in the subframe n and that is indicated by the indication information.

    Abstract: Embodiments of the present disclosure provide a message feedback method and apparatus for carrier aggregation. The method includes: receiving, by a terminal in a first downlink subframe on a carrier aggregation group, a data packet sent by a base station, where the carrier aggregation group includes a first carrier and a second carrier; determining a first timing, based on a subframe configuration for the carrier aggregation group and a mapping relationship between subframe configurations for carrier aggregation groups and timings; determining a first uplink subframe from subframes on the carrier aggregation group based on the first timing; and sending, to the base station, a feedback message in the first uplink subframe. In this way, the first uplink subframe is determined on the entire carrier group for sending the feedback message, and a selectable range is larger.

    Abstract: Embodiments of the present disclosure provide example methods and apparatuses for transmitting pattern information. One example method for transmitting pattern information includes obtaining pattern information and sending the pattern information to UE. The first pattern information indicates that the spectrum of the first cell is allocated to the first RAT in a first plurality of sub-frames and that the spectrum of the first cell is allocated to the second RAT in a second plurality of sub-frames. The first pattern information enables at least one of the UE to select any sub-frame in the first plurality of sub-frames to measure a CRS if the UE RAT pattern corresponds to the first RAT or the UE to select any sub-frame in the second plurality of sub-frames to measure the CRS if the UE RAT pattern corresponds to the second RAT.

    Abstract: This disclosure relates to the mobile communications field, and in particular, to data transmission technologies in the mobile communications field. In a data transmission method, a base station allocates, to a terminal, some of time domain symbols that are used for data transmission and that are in a scheduling period of the terminal, and the terminal performs data transmission based on the allocated time domain symbols. According to the method, time domain symbols in the scheduling period that originally belong to the terminal are punctured, a resource waste caused when the terminal occupies all time domain symbols that are used for data transmission and that are in the scheduling period during scheduling each time can be avoided, so that radio resources can be flexibly allocated based on requirements on delays and bandwidth, thereby improving resource utilization.

    Abstract: Embodiments of the present application provide a data transmission method. The method includes: sending, by user equipment, uplink data to a base station by using an uplink user equipment relay; and receiving, by the user equipment, downlink data from the base station, or receiving, by the user equipment, downlink data from the base station by using a downlink user equipment relay. Uplink transmission and downlink transmission are separately performed in different transmission paths, so as to reduce impact of a fault of a user equipment relay on a network, and improve network reliability.
