Abstract: A resource configuration method and an apparatus are provided. The resource configuration method includes: receiving, by user equipment, configuration information sent by a network device, where the configuration information is used to indicate at least one time interval and at least one time-frequency resource unit within the time interval, and the time-frequency resource unit includes a first time-frequency resource subunit and/or a second time-frequency resource subunit; and reconfiguring, by the user equipment, a resource mapping manner and/or a rate matching manner based on the configuration information, so that no downlink receiving or uplink sending is performed by the user equipment on the first time-frequency resource subunit, and adjusting a timing offset of the second time-frequency resource subunit to perform downlink receiving or uplink sending on the second time-frequency resource subunit obtained by adjusting the timing offset. Resource utilization can be improved while ensuring that the user equipment correctly receives data.

Abstract: An embodiment of this application provides a downlink control information transmission method and an apparatus. The method includes: receiving first downlink control information DCI in search space of a first carrier bandwidth part BWP, where if a frequency domain resource allocation type of the first BWP is a type 0, an Lf-bit frequency domain resource allocation indication in the first DCI is an Lf-bit bitmap, and bits in the Lf-bit bitmap in descending order are respectively corresponding to resource block groups RBG 0 to RBG (Lf−1) in a second BWP; and for one bit in the Lf-bit bitmap, when a value of the bit is t1, an allocated resource includes one RBG corresponding to the bit.

Abstract: A resource determining method is provided. The method includes: determining a time domain position and a resource unit type of a first time domain resource unit based on first configuration information; determining a time domain position of a second time domain resource unit based on the time domain position of the first time domain resource unit, where the time domain position of the second time domain resource unit is at a time domain position which is different from the time domain position of the first time domain resource unit and is within a preset time period; and receiving second configuration information from a network-side device, and determining a resource unit type of the second time domain resource unit based on the second configuration information. Thus, subframe types of various subframes in D-TDD can be determined.
