Title:
TIME DIVISION DUPLEXING COMMUNICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/228035
Kind Code:
A1
Abstract:
Disclosed are a time division duplexing communication method and apparatus, which relate to the technical field of communications, and solve the problem in the prior art of a relatively low data transmission efficiency caused by a lower speed of TDD switching and the inability to support coexistence and switching of multiple sub-carrier interval types under a 5G scenario. A specific solution is: a radio frequency device acquiring a first graph index and a first sub-carrier interval type sent by a baseband device, wherein the first graph index is used for indexing a first graph type corresponding to each orthogonal frequency division multiplexing (OFDM) symbol in a time slot; the radio frequency device configuring a first time slot on the basis of the first graph index and the first sub-carrier interval type, wherein the first time slot is a time slot corresponding to the first sub-carrier interval type, and uplink and downlink indications in the first time slot are switched by taking an orthogonal frequency division multiplexing (OFDM) symbol in the first time slot as a conversion point; and the radio frequency device performing data transmission on the basis of the first time slot.
