Abstract: This application provides a resource configuration method, a terminal, and a network device. The method includes: determining a second frequency domain resource based on a physical random access channel frequency domain resource used by a terminal to send a random access preamble, where the second frequency domain resource is used to transmit at least one of physical signal information or physical channel information. In embodiments of this application, when the network device configures a plurality of uplink frequency domain resources used to send a random access message 3, the terminal may determine a to-be-used uplink frequency domain resource according to the method provided in this application.

Abstract: Various embodiments provide a frequency hopping processing method and a device. In those embodiments, a symbol used to transmit a demodulation reference signal of a shared channel can be determined by a communications device. A time domain frequency hopping location of the shared channel based on the symbol used to transmit the demodulation reference signal can be determined by the communications device. In this way, frequency hopping processing of a shared channel in an NR network is implemented.

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.
