Abstract: A network device sends indication information to a terminal device, to indicate a reference position of a starting symbol of a data channel. The network device sends a physical downlink control channel to the terminal device. Then the network device sends the data channel to the terminal device, or the network device receives the data channel from the terminal device.

Abstract: Embodiments of the present application provide a method for acquiring information of access resources, a terminal device, and a base station. A terminal device detects a synchronization signal of a cell to be accessed by the terminal device. The terminal device further receives a broadcast channel of the cell on a broadcast channel resource. The terminal device then determines a resource on which the cell is located according to resource indication information carried in the broadcast channel. The broadcast channel resource corresponds to an actual access resource, and the synchronization signal is detected on the actual access resource. The actual access resource is one of a plurality of candidate access resources of the cell. The resource indication information indicates a location relationship between the actual access resource and the resource on which the cell is located.

Abstract: This application provides a method to improve resource utilization efficiency of an uplink control channel that carries feedback information. A terminal device receives one or more downlink channels carried in one or more first time units, the first time units belonging to in a time unit set; determines a second time unit for carrying feedback information corresponding to the downlink channels according to a first association relationship between the time unit set and the second time unit; determines a first codebook; and sends uplink control information including the first codebook in the second time unit. When one of the downlink channels is received in first time units that belong to a subset of the time unit set, and there is a second association relationship between the subset of the time unit set and the second time unit, the first codebook includes only feedback information corresponding to the downlink channel carried in the first time units in the subset.

Abstract: This application discloses communication methods and communication apparatuses. A terminal device receives indication information from a network device. The indication information includes one or more indication parameters. The terminal device obtains one or more pieces of configuration information based on the indication parameters. The terminal device performs uplink or downlink data transmission according to the one or more pieces of configuration information. Each pieces of configuration information includes information of a starting location and information of a quantity of time domain symbols in a slot that are occupied by uplink data or downlink data. Each piece of configuration information is selected from a first set of configuration information or a second set of configuration information. The first set of configuration information corresponds to a first mapping type of a physical downlink shared channel (PDSCH) and the second set of configuration information corresponds to a second mapping type of the PDSCH.

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.
