Method and apparatus for control channel design for data transmission on unlicensed spectrum

Abstract

The present application relates to method and apparatus for downlink control channel design for data transmission on unlicensed spectrum. One embodiment of the present disclosure provides a method comprising: dividing a carrier bandwidth into a plurality of bandwidth portions, wherein each of the plurality of bandwidth portions includes a control region for transmitting control channel; performing a channel access test for each of the plurality of bandwidth portions; determining a first bandwidth portion from the plurality of bandwidth portions according to channel access test results of the plurality of bandwidth portions; transmitting a first control channel in a first control region of the first bandwidth portion, wherein the first control channel is used for scheduling a data transmission in one or more bandwidth portions of the plurality of bandwidth portions.
