Description

基站、用户设备和相关方法Base station, user equipment, and related methods 技术领域Technical field

本发明涉及无线通信技术领域，更具体地，本发明涉及TDD NB-IoT的帧结构设计方案。The present invention relates to the field of wireless communication technologies, and more particularly, to a frame structure design scheme of TDD NB-IoT.

背景技术Background technique

在2015年9月举行的3GPP RAN#69此次全会上，提出了一个新的工作项目(参见非专利文献：RP-151621 New Work Item：NarrowBand IoT(NB-IoT))，我们称之为窄带物联网(Narrowband Internet of Thing，NB-IoT)。在该项目的描述中，NB-IoT的用户设备(User Equipment，UE)将支持上下行180KHz的射频带宽。At the 3GPP RAN #69 plenary session held in September 2015, a new work project was proposed (see Non-Patent Document: RP-151621 New Work Item: NarrowBand IoT (NB-IoT)), which we call narrowband Internet of Things (Narrowband Internet of Thing, NB-IoT). In the description of the project, the User Equipment (UE) of the NB-IoT will support the uplink and downlink 180KHz radio frequency bandwidth.

在2017年6月举行的3GPP RAN#76此次全会上，提出了一个新的工作项目(参见非专利文献：RP-171428 Revised WID on Further NB-IoT enhancements)，其中着重研究TDD场景下的通信流程。At the 3GPP RAN #76 plenary session in June 2017, a new work project was proposed (see Non-Patent Document: RP-171428 Revised WID on Further NB-IoT enhancements), which focuses on communication in TDD scenarios. Process.

在FDD NB-IoT中，NPUSCH支持single-tone与multi-tone两种传输模式。其中在single-tone传输模式下，又同时支持3.75kHz与15kHz子载波间距(subcarrier spacing)的传输方式。针对3.75kHz的NPUSCH传输，专门设计了包含有7个符号的时隙(slot)。其中，该slot的持续时长是2ms，且每个符号的CP长度是256·Ts，符号的时间长度是8192·Ts，slot的末端的保护时间是2304·Ts。In FDD NB-IoT, NPUSCH supports both single-tone and multi-tone transmission modes. Among them, in the single-tone transmission mode, it also supports the transmission mode of 3.75 kHz and 15 kHz subcarrier spacing. For the 3.75 kHz NPUSCH transmission, a slot containing 7 symbols is specifically designed. The duration of the slot is 2 ms, and the CP length of each symbol is 256·Ts, the length of the symbol is 8192·Ts, and the protection time of the end of the slot is 2304·Ts.

Ts是基本时间单位，在不同的通信系统中可能取不同的值。比如在LTE、LTE-A以及LTE-pro等通信系统中，30720·Ts＝1ms。Ts is the basic unit of time and may take different values in different communication systems. For example, in a communication system such as LTE, LTE-A, and LTE-pro, 30720·Ts=1 ms.

在TDD NB-IoT中，需要在考虑到已有的TDD uplink-downlink configuration的具体上下行结构下，设计新的时隙结构。In TDD NB-IoT, a new slot structure needs to be designed under the specific uplink and downlink structure considering the existing TDD uplink-downlink configuration.
