    Abstract: This application provides a resource mapping method, a network device, and a terminal device. The method includes: generating, by a network device, control information, where the control information is used to indicate at least one type of the following information: at least one bandwidth region in which at least one frequency domain resource unit is located, a granularity of the frequency domain resource unit, and a location of the frequency domain resource unit in the bandwidth region; and sending, by the network device, the control information to a terminal device. The frequency domain resource unit is a scheduling unit of a frequency domain resource used when the network device and the terminal device transmit a data channel. The granularity of the resource unit corresponds to a granularity of a resource unit used when the network device and the terminal device transmit a control channel.

    Abstract: Embodiments provide resource scheduling method, user equipment, and an access network device. The method includes: receiving, by user equipment over a first control channel, first indication information corresponding to a transport block, where time-frequency resources occupied by a data channel in which the transport block is located include a first resource set and a second resource set, and the first indication information is used to indicate the first resource set and a time-frequency resource of a second control channel; receiving, by the user equipment, second indication information over the second control channel, where the second indication information is used to indicate the second resource set; and determining, by the user equipment, the transport block based on the first resource set and the second resource set. This can reduce control signaling overheads and improve flexibility of control channel resource scheduling.

    Abstract: Embodiments of the present invention provide a resource mapping method and an apparatus, and relate the communications field, so as to flexibly implement resource mapping of a channel or a signal. First information is obtained. The first information is used to indicate a cyclic shift start resource block location or a cyclic shift end resource block location for resource mapping of a first channel or a first signal in a resource block cyclic shift manner in a bandwidth used by user equipment. A resource mapping location of the first channel or the first signal in the bandwidth used by the user equipment is determined according to the resource block cyclic shift manner and the first information. The first channel or the first signal is received or sent at the resource mapping location. The resource mapping method and the apparatus are used to map a resource.
