Description

一种数据通信的方法、终端设备及网络设备 技术领域
本发明涉及通信技术领域,尤其涉及一种数据通信的方法、终端设备及网络设备。
背景技术
随着无线通信技术的飞速发展,用户对数据传输速率的需求也越来越高。LTE(Long Term Evolution,长期演进)系统可通过高率、低时延和扁平的网络架构,提供一种高速数据网络,以满足用户不断增长的速率传输需求。
在当前的LTE系统中,终端设备在TTI(Transmission Time Interval,传输时间间隔)内通过上行信道向网络设备发送信息,信息一般包括数据、参考信号和CSI(Channel State Information,信道状态信息)等。其中CSI包括PMI(Precoding Matrix Indicators,预编码矩阵指示)、RI(Rank Indicator,秩指示)和CQI(Channel Quality Indicator,信道质量指示)中的至少一种。网络设备根据终端设备发送的CSI,对终端设备进行下行调度以及下行信息传输。
在当前的LTE系统中,TTI的时长为1ms,为了实现更短的往返时间和更短的数据传输时延,提出了将TTI缩短的技术。然而,在TTI缩短的情况下,终端设备会没有足够的上行传输资源传输信息,进而网络设备无法获取到数据、参考信号,或者CSI,从而就会降低系统的下行容量。
综上所述,在短TTI的场景下,目前发送或者接收上行信息的方法存在网络设备无法接收到部分信息的情况,进而导致系统容量较低的缺陷。

具体实施方式
为了使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明作进一步地详细描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例,都属于本发明保护的范围。
下面对本发明所适用的应用领域、基本技术进行描述,以便更好的理解本发明。
本发明实施例的技术方案,可以应用于各种通信系统,例如:GSM(Global System for Mobile Communication,全球移动通信)系统、CDMA(Code Division Multiple Access,码分多址)系统,WCDMA(Wideband Code Division Multiple Access Wireless,宽带码分多址)系统,GPRS(General Packet Radio Service,通用分组无线业务),LTE(Long Term Evolution,长期演进)系统等。
终端设备(Terminal Device),也可称之为移动终端(Mobile Termina)、移动终端设备等,在此不做具体限定,可以经无线接入网(例如,RAN(Radio Access Network,居民接入网))与一个或多个核心网进行通信,终端设备可以是移动终端,如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动 装置,它们与无线接入网交换语言和/或数据。
网络设备,可以是GSM或CDMA中的基站(BTS,Base Transceiver Station),也可以是WCDMA中的基站(NodeB),还可以是LTE中的演进型基站(eNB或e-NodeB,evolutional Node B),本发明实施例并不进行具体限定。
1ms的TTI在时域上就是一个子帧(subframe),一个subframe由两个时隙(slot)组成。每个slot包括6个或者7个符号(symbol)。在一个slot上的资源格式如图1A所示,其中,一个RB(Resource Block,资源块)(或PRB(Physical Resource Block,物理资源块))是由频域上12个子载波*时域上6个或者7个符号组成,当CP(Cyclic Prefix,循环前缀)为正常CP时,一个RB在时域上取值为7,当CP为扩展CP时,一个RB在时域上取值为6。一个RE(Resource Element,资源元素)是由频域上1个子载波*时域上1个符号组成,一个PRB对由一个subframe上两个slot上相同频域的两个PRB组成。
本发明实施例中,当TTI为1ms时,终端设备会在第n个子帧收到上行信息的指示信息,如上报CSI的指示信息,然后,终端设备在第n+k个子帧发送上行信息,可选的,k可以为4,当k为4时,时序关系如图1B所示。
当TTI为1ms的现有技术中,CSI包括周期CSI和非周期CSI,周期CSI是终端设备周期性的发送CSI,非周期CSI是网络设备通过DCI(Downlink Control Information,下行控制信息)中的CSI指示信息通知终端设备,终端设备会在对应的TTI上发送CSI。非周期CSI仅在PUSCH(Physical uplink Shared Channel,物理上行共享信道)上传输,假设终端仅被分配了一个子帧上的一个PRB对,PUSCH的格式如图1C所示,从图1C可以看出CSI在PUSCH信道中的分布情况,周期CSI可以在PUSCH上传输,也可以在PUCCH(Physical uplink Control Channel,物理上行控制信道)上传输,即如果当前TTI所在子帧本身有PUSCH发送,那么周期CSI就可以在PUSCH或PUCCH上传输,如果当前TTI所在子帧上没有PUSCH发送,那么周期CSI就只能在PUCCH上传输。在现有技术中,如果周期CSI和非周期CSI同时在同一个子帧中碰撞了,那么终端设备只会发送非周期CSI在这个子帧上。
“多个”是指两个或两个以上。“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
下面结合附图对本发明实施例进行详细说明。
参阅图2A所示,本发明实施例中,一种数据通信的流程如下:
步骤200:终端设备在第一时间段上接收第一指示信息,其中,第一时间段的长度为第一时间单元,第一指示信息用于触发终端设备在第二时间段上发送第一信息;

其中,第二时间段与第一时间段之间间隔K个第一时间单元,K为正整数,第二时间段的第一个符号的起始位置与第一子帧的第一个符号的起始位置相同,第一子帧为与第一时间段所在子帧的相邻子帧,或者,为与第一时间段间隔K个第一时间单元的第一时间段所在子帧,或者,为与第一时间段间隔K个第一时间单元的第一时间段所在子帧的相邻子帧。
其中,第一子帧为与第一时间段所在子帧的相邻子帧时,可以如图2B所示,此时,子帧2为第一子帧;
第一子帧为与第一时间段间隔K个第一时间单元的第一时间段所在子帧时,可以如图2C所示,此时,子帧2为第一子帧,或者,也可以如图2D所示,此时,子帧3为第一子帧;
第一子帧为与第一时间段间隔K个第一时间单元的第一时间段所在子帧的相邻子帧时,可以如图2B所示,此时,子帧2为第一子帧,或者,也可以如图2E所示,此时,子帧3为第一子帧。

需要说明的是,终端设备具有在长度为第一时间单元的时间段和长度为第二时间单元的时间段内同时发送信息的能力,可以理解为当长度为第一时间单元的时间段和长度为第二时间单元的时间段发生重叠时,终端设备具有在第二时间单元和第一时间单元上同时发送信息的能力;终端设备被配置在长度为第一时间单元的时间段和长度为第二时间单元的时间段同时发送信息,可以理解为当长度为第一时间单元的时间段和长度为第二时间单元的时间段发生重叠时,终端设备被网络设备配置允许在长度为第一时间单元的时间段和长度为第二时间单元的时间段上同时发送信息。

终端设备在第二时间段之后的第J个第一时间段上发送第二信息,所J为大于或者等于1的正整数。
本发明实例中,终端设备接收第一指示信息和发送第一信息的载波可以为同一载波,也可以为不同载波。因此,本发明实施例中,终端设备在第一时间段上接收第一指示信息时,可选的,可以采用如下方式:

本发明实施例中所描述的多于一个与至少两个所表达的意思相同,可以替换使用,在此不做具体限定。
需要说明的是,本发明实施例中,终端设备被配置能够执行某些操作或者具有某些能力时,可以根据接收到的网络设备发送的配置信息来确定的,因此,进一步的,终端设备接收网络设备发送的第一配置信息、第二配置信息和第三配置信息中的至少一种,第一配置信息用于给终端设备仅配置一个上行载波,进一步的,第一配置信息还可以用于指示给终端设备配置多于一个上行载波、第二配置信息用于指示配置终端设备在长度为第一时间单元的时间段和长度为第二时间单元的时间段内同时发送信息的能力,进一步的,第二配置信息还用于指示未配置终端设备在长度为第一时间单元的时间段和长度为第二时间单元的时间段内同时发送信息的能力、第三配置信息用于指示配置终端设备接收信息的时间段的长度与发送信息的时间段的长度不同,进一步的,第三配置信息还用于指示配置终端设备接收信息的时间段的长度与发送信息的时间段的长度相同。
例如,终端设备被配置在长度为第一时间单元的时间段和长度为第二时间单元的时间段内同时发送信息的能力时,可以为终端设备接收网络设备发送的第二配置信息,终端设备根据第二配置信息确定被配置在在长度为第一时间单元的时间段和长度为第二时间单元的时间段同时发送信息的能力。
又例如,终端设备未被配置在长度为第一时间单元的时间段和长度为第二时间单元的时间段内同时发送信息的能力,可以为终端设备未接收到网络 设备发送的第二配置信息。
又例如,终端设备配置终端设备接收信息的时间段的长度与发送信息的时间段的长度不同,可以为终端设备接收第三配置信息,并根据第三配置信息确定被配置在不同长度的时间段上发送信息和接收信息。
又例如,终端设备确定未被配置多于一个的上行载波,可以为终端设备未接收到网络设备发送的第一配置信息时,确定未被配置多于一个的上行载波,或者,终端设备接收网络设备发送的第二配置信息,根据第二配置信息确定未被配置多于一个的上行载波或被配置仅一个的上行载波。
其中,第三配置信息用于指示配置终端设备接收信息的时间段的长度与发送信息的时间段的长度不同,可以指用于指示配置终端设备在第一时间段上接收信息,在第二时间段上发送信息。例如,在第一时间段上接收PDSCH(Physical Downlink Share Channel,物理下行共享信道)信道,即PDSCH信道是以第一时间段的长度发送的;在第二时间段上发送PUSCH信道,即PUSCH信道是以第二时间段的长度发送的。
可选的,PUSCH在1ms TTI上发送,PDSCH在2OFDM符号上接收。
在该实施例中,终端设备在第一时间段上接收第一指示信息,终端设备在第二时间段上发送第一信息,第一时间段的长度为第一时间单元,第二时间段的长度为第二时间单元,第二时间单元的长度大于第一时间单元的长度;这样,虽然终端设备在第一时间单元N上接收第一指示信息,但是,终端设备在大于第一时间单元的长度的第二时间单元M上发送第一信息,避免了终端设备没有足够的上行传输资源传输第一信息,降低系统的容量缺陷。
参阅图3所示,本发明实施例中,一种数据通信的流程如下:

步骤310:网络设备在第一时间段上向终端设备发送第一指示信息,其中,第一时间段的长度为第一时间单元,第一指示信息用于触发终端设备在第二时间段上发送第一信息,第二时间段的长度为第二时间单元,第二时间单元的长度大于第一时间单元的长度;
其中,第二时间段与第一时间段之间间隔K个第一时间单元,K为正整数,第二时间段的第一个符号的起始位置与第一子帧的第一个符号的起始位置相同,第一子帧为与第一时间段所在子帧的相邻子帧,或者,为与第一时间段间隔K个第一时间单元的第一时间段所在子帧,或者,为与第一时间段间隔K个第一时间单元的第一时间段所在子帧的相邻子帧。

需要说明的是,网络设备接收第一信息的前提是,网络设备确定终端设备不具有上行多载波发送能力,和/或网络设备未向终端设备发送配置不多于一个的上行载波的指示信息。
终端设备不具有上行多载波发送能力,可以理解为网络设备根据终端设备上报的能力信息,确定终端设备仅仅具有上行单载波发送能力,即终端设备只具有在一个上行载波上发送信息的能力。
网络设备未向终端设备发送配置不多于一个的上行载波的指示信息,可以理解为终端设备根据指示信息,确定终端设备未被配置在多于一个的上行载波,即终端设备仅被配置了一个上行载波。

又例如,终端设备未被配置在长度为第一时间单元的时间段和长度为第二时间单元的时间段内同时发送信息的能力,可以为终端设备未接收到网络设备发送的第二配置信息。
又例如,终端设备配置终端设备接收信息的时间段的长度与发送信息的时间段的长度不同,可以为终端设备接收第三配置信息,并根据第三配置信息确定被配置在不同长度的时间段上发送信息和接收信息。

在该实施例中,终端设备在第一时间段上接收第一指示信息,终端设备在第二时间段上发送第一信息,第一时间段的长度为第一时间单元,第二时间段的长度为第二时间单元,第二时间单元的长度大于第一时间单元的长度;这样,虽然终端设备在第一时间单元N上接收第一指示信息,但是,终端设备在大于第一时间单元的长度的第二时间单元M上发送第一信息,避免了终端设备没有足够的上行传输资源传输第一信息,降低系统的容量缺陷。
