Title:
SCHEDULING INFORMATION SENDING METHODS, SCHEDULING INFORMATION RECEIVING METHODS AND APPARATUSES
Document Type and Number:
WIPO Patent Application WO/2022/134061
Kind Code:
A1
Abstract:
The disclosure relates to the technical field of communications, and provided therein are scheduling information sending methods, scheduling information receiving methods and apparatuses. The solution is: receiving channel state information sent by a terminal device; generating scheduling information according to the channel state information, the scheduling information comprising current frequency hopping and adjacent frequency hopping within one time unit, the carrier frequency of the current frequency hopping being located in a coherent bandwidth of the adjacent frequency hopping, and a pilot signal configured on the current frequency hopping or adjacent frequency hopping being used for channel estimation of the current frequency hopping and/or adjacent frequency hopping; and sending the scheduling information to a terminal device. In the present disclosure, when the carrier frequency of the current frequency hopping is located within the coherent bandwidth of the adjacent frequency hopping, the pilot signal configured on the current frequency hopping or adjacent frequency hopping is used for channel estimation of the current frequency hopping and/or adjacent frequency hopping, that is, the current frequency hopping and the adjacent frequency hopping may share a pilot signal, and the amount of pilot signals can be effectively reduced, increasing the transmission of data information, thereby improving coverage performance.
