中文摘要 | 載波叢聚(carrier aggregation)是無線通訊系統中增加服務頻寬的方法。此功能允許基地台利用多個分量載波(component carrier, CC)的無線資源來同時服務用戶端以有效地增加可使用的頻譜資源。同時,一個具有載波叢聚存取能力的用戶端可以同時於多個分量載波上執行接收及 (/或)傳送的功能。為了增進上行資源的使用效率以及相容於相鄰頻帶舊系統的運行以避免鄰頻干擾,一個使用分時多工 (time-division duplex, TDD)的基地站台中的多個分量載波可以被指派分別使用不同的上傳下傳規則(UL-DL configuration)。本文中,我們將提出在具有上述特性的分時多工無線通訊系統中,用戶端如何正確且有效率的回傳混合式自動重傳請求 (Hybrid Automatic Repeat Request, HARQ)訊息的的方法。 |
英文摘要 | Carrier aggregation (CA) is a mechanism to increase the bandwidth of a wireless communication system. This feature allows scalable expansion of effective bandwidth delivered to a user terminal through concurrent utilization of radio resources across multiple component carriers (CCs). A UE with reception and/or transmission capabilities for CA can simultaneously receive and/or transmit on multiple CCs corresponding to multiple serving cells. In order to improve UL capacity/coverage and to keep compatibility with legacy TDD systems on the same or adjacent band, it is possible to use other TDD configuration on other CCs. In this paper, we present our view on designing the method for Hybrid Automatic Repeat Request (HARQ) report while the UE is served by a TDD system with CA function and each CC may have different UL-DL configuration. |
