Description

用户设备、基站及其功率控制方法 技术领域
本发明涉及无线通信技术领域，更具体地，本发明涉及短时传输时间间隔(Short Transmission Time Interval，sTTI)下的功率控制方法，以及基站和用户设备。
背景技术
现代无线移动通信系统呈现出两个显著特点，一是宽带高速率，比如第四代无线移动通信系统的带宽可达100MHz，下行速率高达1Gbps；二是移动互联，推动了移动上网、手机视频点播、在线导航等新兴业务。这两个特点对无线移动通信技术提出了较高要求，主要有：超高速率无线传输、区域间干扰抑制、移动中可靠传输信号、分布式/集中式信号处理等等。
在2016年6月举行的3GPP RAN 72全会上，提出了一个新的工作项目(参见非专利文献：RP-161044：New WID for LTE：Latency reduction by processing time reduction)。在该项目的前期研究(study item，SI)中，Latency Reduction技术将在上行和下行同时支持短时TTI(short TTI，sTTI)，其中1个sTTI包含的OFDM的数目小于14，其可以包含2个OFDM符号或7个OFDM符号，或者是其他小于14的数目。该项目支持的下行信道有短时物理下行控制信道(Short Physical Downlink Control Channel，sPDCCH)和短时物理下行共享信道(Short Physical Downlink Shared Channel，sPDSCH)，支持的上行信道有短时物理上行控制信道(Short Physical Uplink Control Channel，sPUCCH)和短时物理上行共享信道(Short Physical Uplink Shared Channel，sPUSCH)，其中sPDCCH、sPDSCH、sPUCCH以及sPUSCH都是以sTTI作为传输时间间隔的物理信道。sPDCCH用于 传输下行控制信息，sPDSCH用于传输下行数据信息，sPUCCH用于传输上行控制信息，sPUSCH用于传输上行数据信息。
同时，很多公司提出希望UE同时支持Latency reduction的sTTI和LTE/LTE-A的TTI，其中LTE/LTE-A的TTI时间长度为1ms包含有14个OFDM符号。本发明中，TTI指的是LTE/LTE-A的持续周期为1ms且包含14个OFDM符号的子帧(subframe)或者传输时间间隔；sTTI指的是持续周期小于1ms且包含小于14个OFDM符号的子帧(subframe)或者传输时间间隔，其可以包含2个OFDM符号或7个OFDM符号，或者是其他小于14的数目。
UE在latency reduction模式下可以同时支持sTTI和TTI的传输，此时UE有可能同时支持PUCCH，PUSCH，sPUCCH和sPUSCH，或者支持以上四种不同信道的任意子集。此时，如何设计sPUCCH以及sPUSCH的功率将会是一个不可回避的问题。
因此，本发明解决的问题是：UE同时支持sTTI和TTI时，如何分配sPUCCH以及sPUSCH的功率。
发明内容
为解决上述问题中的至少一些，本发明的实施例提供了一种用户设备、一种基站及其对应的功率控制方法。
根据一个方案，提供了一种用户设备，包括：接收机，用于从基站接收配置信息，所述配置信息指示用户设备在短时传输时间间隔sTTI上传输的信道类型以及所述用户设备在传输时间间隔TTI上传输的信道类型；以及功率计算单元，用于根据接收到的配置信息计算向短物理上行控制信道sPUCCH和/或短物理上行共享信道sPUSCH分配的功率。
根据另一方案，提供了一种基站，包括：配置信息生成器，用于生成配置信息，所述配置信息指示用户设备在短时传输时间间隔sTTI上传输的信道类型以及所述用户设备在传输时间间隔上传输的信道类型；发射机，用于向所述用户设备发送所述配置信息。
根据另一方案，提供了一种功率控制方法，包括：从基站接收配置信息，所述配置信息指示用户设备在短时传输时间间隔sTTI上传输的信道类型以及所述用户设备在传输时间间隔TTI上传输的信道类型；以及根据接收到的配置信息计算向短物理上行控制信道sPUCCH和/或短物理上行共享信道sPUSCH分配的功率。
根据又一方案，提供了一种功率控制方法，包括：生成配置信息，所述配置信息指示用户设备在短时传输时间间隔sTTI上传输的信道类型以及所述用户设备在传输时间间隔上传输的信道类型；向所述用户设备发送所述配置信息。
上述方案解决了UE同时支持sTTI和TTI时，如何分配sPUCCH以及sPUSCH的功率的问题。
