Abstract: The present disclosure describes methods, user equipment, and base stations for sending feedback information. One example method includes: sending scheduling information on a downlink control channel to user equipment, wherein the downlink control channel is in a downlink subframe which belongs to a preconfigured downlink subframe set, and the scheduling information is used for scheduling downlink data; determining an uplink subframe for receiving feedback information corresponding to the downlink data, wherein the preconfigured downlink subframe set is a set of downlink subframes that are associated with the uplink subframe and that are of all carriers configured for the user equipment by the base station; sending PUCCH resource indication information to the user equipment for indicating a PUCCH resource.

Abstract: This application discloses a method for a hybrid automatic repeat request (HARQ) feedback of downlink data. A terminal receives downlink data of a physical downlink shared channel (PDSCH) and downlink data of a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (EPDCCH) from a base station. Then the terminal sends a hybrid automatic repeat request (HARQ) feedback codebook to the base station. A size of the HARQ feedback codebook is based on a state of a semi-persistent scheduling (SPS) PDSCH transmission and a total downlink assignment indicator in the downlink data of the PDCCH or the EPDCCH, and the HARQ feedback codebook comprises a HARQ bit for the SPS PDSCH transmission.

Abstract: A terminal receives downlink scheduling information of a downlink subframe F(i, j), where a set M of preconfigured downlink subframes in which the downlink subframe F(i, j) is located is divided into N subsets of preconfigured downlink subframes, a bit quantity of a hybrid automatic repeat request-acknowledgement HARQ-ACK that needs to be fed back for each downlink subframe in one subset of preconfigured downlink subframes is a predetermined value, and bit quantities of HARQ-ACKs that need to be fed back for any downlink subframes in different subsets of preconfigured downlink subframes are different. The terminal generates a HARQ-ACK codebook according to a receiving status of downlink data. And the terminal generates uplink control information after encoding the HARQ-ACK codebook; and a sending module sends the uplink control information.

Abstract: An apparatus for band-limited frequency division multiplexing for uplink transmission to a base station or access point, particularly from an IoT device, comprises a signal modulator to transmit a signal over a set of contiguous equally spaced frequency sub-carriers ranging from a lowest frequency sub-carrier via intermediate sub-carriers to a highest frequency sub-carrier. The signal modulator contains a filter to apply asymmetric filtering over the range of the frequency sub-carriers, thereby to reduce a peak-to-average power ratio of the transmitted signal.

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: The present disclosure relates to a method and an apparatus for sending and receiving a downlink data block of a packet data service. A network side adds indication information of downlink data modulation modes to a downlink data block, where the downlink data block includes first information and second information; the network performs symbol mapping processing on the first information by using a first modulation mode to obtain a first modulated signal; the network performs symbol mapping processing and data pre-processing on the second information by using a second modulation mode to obtain a second modulated signal; the network combines these two modulated signals to obtain an aggregate modulated signal; and the network sends the aggregate modulated signal. With the present disclosure, throughput of downlink data is increased while a USF compatibility between more types of low-capability mobile terminals is considered.
