CONTROL INFORMATION RECEPTION METHOD AND USER EQUIPMENT, AND CONTROL INFORMATION RECEPTION METHOD AND BASE STATION

摘要

Provided are method and device for transmitting/receiving control information. A downlink grant can comprise information indicating whether or not an uplink grant is transmitted in the same subframe. If the information indicates that an uplink grant exists, a user equipment attempts detection of the uplink grant in the same subframe in which the downlink grant is received. If not, the user equipment does not attempt detection of the uplink grant. For low latency, the subframe can be shorter than an existing subframe.
