Title:
METHOD AND DEVICE FOR USE IN USER EQUIPMENT AND BASE STATION FOR WIRELESS COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2019/213798
Kind Code:
A1
Abstract:
Disclosed are a method and device for use in user equipment and base station for wireless communication, the method comprising: a user equipment receives first signaling and performs an operation on a first wireless signal, the first signaling being used for indicating a first sub-carrier set and a second sub-carrier set, a frequency domain resource occupied by the first wireless signal comprising the first sub-carrier set and the second sub-carrier set, the difference between central frequency points of any two sub-carriers in the first sub-carrier set being a positive integral multiple of a first sub-carrier interval, and the difference between a central frequency point of at least one sub-carrier in the first sub-carrier set and a central frequency point of a sub-carrier in the second sub-carrier set cannot be divided by the first sub-carrier interval with no reminder. By designing the first sub-carrier set and the second sub-carrier set, the present application improves the spectrum efficiency and the overall system performance during the coexistence of 5G transmission and narrow band Internet of Things transmission.
