Abstract: Current frame structures in Long-Term Evolution (LTE) and New Radio (NR) are not designed to accommodate full duplex (FD) communication. Embodiments are disclosed in which frame structures are provided that support FD communication and frequency division duplex (FDD) communication and time division duplex (TDD) communication. In some embodiments, there is defined two separate and independent frame structures: a frame structure for reception (e.g. a downlink frame structure) and a frame structure for transmission (e.g. an uplink frame structure).

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.
