Title:
無認可スペクトルを使用した送信機管理
Document Type and Number:
Japanese Patent JP6479819
Kind Code:
B2
Abstract:
Management of transmitters is disclosed for conditions of transmission uncertainty that arises in operating over non-guaranteed transmission carriers that are required to perform listen-before-talk (LBT) processes and guaranteed transmission carriers that are LBT-exempt. Due to the hardware and software constraints, techniques are described to pre-prepare data and control transmissions or provide the transmitters additional time to prepare for such data and control transmissions based on the results of clear channel assessment (CCA) checks of the non-guaranteed transmission carriers.
