Abstract: Embodiments of the present invention provide a communication method for a carrier aggregation system. The communication method includes receiving physical downlink share channel PDSCH information sent by a base station through a subframe n of a secondary cell. If a subframe n of a primary cell is a downlink subframe, an ACK/NACK of the sent PDSCH information is fed back on a subframe m or a subframe p of the primary cell.

Abstract: A method for determining a search space includes determining the number of downlink control information bits of each type of control channel currently required to be monitored by a UE. A temporary search space corresponding to the each type of control channel is determined according to a mapping relationship currently used by the UE. It is determined that an actual search space corresponding to a selected type of control channel is all or a part of CCEs of a union of temporary search spaces corresponding to all or a part of control channels with the same number of the downlink control information bits when the DCI bit number of one or more other control channels is the same as the DCI bit number of the selected type of control channel.

Abstract: A method for aggregation transmission of multi-user downlink data and an apparatus. A network device performs, based on a specific aggregation rule, bit aggregation on downlink data of a terminal device in a terminal device group, performs channel encoding and modulation on data obtained through the bit aggregation, and sends the data to a plurality of terminal devices participating in aggregation transmission. Each terminal device that receives the downlink data obtains, based on the aggregation rule, respective downlink data from the received data obtained through the bit aggregation. According to this method, the network device performs channel encoding on an aggregated bit sequence, thereby increasing a sequence length before encoding, and improving a coding gain.

Abstract: Embodiments of this application provide a communication method and an apparatus, relate to the communication field, and in particular, are applicable to a broadcast system. The method includes: A terminal device receives a first downlink channel from an access network device, where the first downlink channel is scrambled by using a first identifier and is used to carry first data. The terminal device receives a second downlink channel from the access network device, where the second downlink channel is scrambled by using a second identifier and is used to retransmit the first data. The first identifier and the second identifier are identifiers configured by the access network device. This method can implement a feedback retransmission mechanism combining broadcast initial transmission and partial retransmission, to further improve spectral efficiency of a communication system.

Abstract: This application provides a method for transmitting hybrid automatic repeat request HARQ feedback information and a communications apparatus. A terminal device receives downlink data channels. Each of the downlink data channels has a corresponding transmission parameter group, and at least two downlink data channels correspond to different transmission parameter groups. The terminal device determines a first transmission resource based on first information including the transmission parameter groups, and sends, on the first transmission resource, HARQ feedback information corresponding to the downlink data channels, so that a plurality of pieces of HARQ feedback information can be smoothly fed back. This helps improve service transmission reliability.
