Summary:To provide a timing advance design for an enhanced component carrier.SOLUTION: Methods, systems, and devices for wireless communication are described. A base station may establish a transmission gap between downlink (DL) transmission and uplink (UL) transmissions on a shared radio frequency (RF) spectrum band using time division duplex (TDD). Length of the gap may be based at least in part on maximum allowed length of a filler signal corresponding to a coverage area of the base station. To reserve a shared band, a user device (UE) may communicate the filler signal for length of time that is based at least in part on the maximum allowed length and geographic distance between the UE and the base station. The UE farther from the base station transmits the filler signal of shorter length before sending UL transmission, so that the UL transmission from a different UE arrives at the same time at the base station regardless of the geographic distance between the UEs.SELECTED DRAWING: Figure 2 【課題】拡張コンポーネントキャリアのためのタイミングアドバンス設計を提供する。【解決手段】ワイヤレス通信のための方法、システム、およびデバイスについて説明する。基地局は、時分割複信(TDD)を使用する共有無線周波数(RF)スペクトル帯域上でダウンリンク(DL)送信とアップリンク(UL)送信との間の送信ギャップを確立し得る。ギャップの長さは、基地局のカバレージエリアに対応するフィラー信号の最大許容長さに少なくとも部分的に基づき得る。共有帯域を確保するために、ユーザ機器(UE)は、最大許容長さおよびUEと基地局との間の地理的距離に少なくとも部分的に基づく時間の長さの間に、フィラー信号を通信し得る。基地局から遠いUEは、UL送信を送る前に、より短い長さのフィラー信号を送信し、その結果、異なるUEからのUL送信は、UE間の地理的距離にかかわらず、基地局に同時に到着する。【選択図】図2
