Title:

METHOD AND DEVICE IN RADIO COMMUNICATIONS

Document Type and Number:

WIPO Patent Application WO/2018/095199

Kind Code:

A1

Abstract:

Disclosed are a method and device in radio communications. A base station sends a first radio signal over a first frequency-domain resource in a first time window, and then sends first signaling. The center frequency of the first frequency-domain resource is a first frequency; the first frequency-domain resource comprises X subcarriers; the carrier to which the first frequency-domain resource belongs is a first carrier; the center frequency of the first carrier is a second frequency; the space in frequency domain between the first frequency and the second frequency is related to a subcarrier space of the X subcarriers. The first radio signal is used for determining at least one of the position of the first time window in a time domain and the first frequency. The first signaling is used for determining a corresponding feature ID of a sender of the first radio signal on the first carrier. The method provided in the present invention can independently configure the center frequency of a carrier and the center frequency of a user equipment, thereby reducing the complexity of synchronization while avoiding a waste of resources.
