Abstract: A radio resource scheduling method and a related device are provided. In the method: a terminal determines a channel status of a channel according to at least one of first status information that is of the channel and that is indicated by a secondary eNodeB or second status information that is of the channel and that is obtained by the terminal. The terminal sends, to a master eNodeB, a first notification message configured to indicate the channel status, so that the master eNodeB performs radio resource scheduling for the terminal according to the first notification message. When the secondary eNodeB has not yet performed scheduling for the terminal, the master eNodeB allocates more radio resources to the terminal, and can obtain more chances for allocating a radio resource.

Abstract: The present invention provides a channel monitoring method and device. The method includes: receiving, by user equipment (UE), a first notification message sent by a base station, where the first notification message includes usage information of a frequency resource of a second carrier; determining, by the UE according to the first notification message, whether the frequency resource of the second carrier is in an available state; and if the UE determines that the frequency resource of the second carrier is in the available state, monitoring a PDCCH corresponding to the second carrier; otherwise, stopping monitoring a PDCCH corresponding to the second carrier, where the second carrier is a carrier on which the UE operates on a discontinuously occupied frequency resource. According to the foregoing method, the UE can properly use an unlicensed frequency to communicate with the base station, and meanwhile reduce power consumption of the UE.

Abstract: Embodiments of this disclosure provide a communication method and a related device. In certain embodiments, the method includes determining, by a network device, a first resource set, the resources included in the first resource set are periodic. At a same transmission moment, the first resource set serves only one terminal device or one terminal device group, the terminal device group including a plurality of terminal devices. At different transmission moments, resources used for co-directional transmission in the first resource set occupy a same frequency domain position on a same carrier. The method includes sending, by the network device, resource configuration information to the terminal device by using higher layer signaling. The resource configuration information is used to indicate the first resource set.

Abstract: Embodiments of the present disclosure provide a method for transmitting a service in a wireless communication network. The service is transmitted by a terminal device to a base station. The terminal device receives from the base station, information of a correspondence between a data radio bearer (DRB) and a radio interface technology supported in a frequency range of a cell. The frequency range is one of N frequency ranges, wherein N≥2. The terminal device also receives characteristic information of the radio interface technology, which includes a subcarrier spacing. The terminal device transmits the service on the DRB within the frequency range using the subcarrier spacing of the radio interface technology.
