  • Table 1 The configuration of the seven types of uplink and downlink subframes executed in FS2 is shown in Table 1.

技术领域
本公开涉及通信技术领域，特别涉及一种上行传输方法及装置。
背景技术
现有Long Term Evolution Time-Division Duplex LTE FDD(频分双工)系统使用帧结构(frame structure type 1，简称FS1)，其结构如图1所示。在FDD系统中，上行和下行传输使用不同的载波频率，上行和下行传输均使用相同的帧结构。在每个载波上，一个10ms长度的无线帧包含有10个1ms子帧，每个子帧内又分为0.5ms长的时隙，上行和下行数据发送的Transmission Time Interval TTI时长为1ms。
现有Long Term Evolution Time-Division Duplex LTE TDD(时分双工)系统使用帧结构(frame structure type 2，简称FS2)，其结构如图2所示。在TDD系统中，上行和下行传输使用相同的频率上不同子帧或不同时隙。FS2中每个10ms无线帧由两个5ms半帧构成，每个半帧中包含5个1ms长度的子帧。FS2中的子帧分为三类：下行子帧、上行子帧和特殊子帧，每个特殊子帧由下行传输时隙(DwPTS，Downlink Pilot Time Slot)、保护间隔(GP，Guard Period)和上行传输时隙(UpPTS，Uplink Pilot Time Slot)三部分构成。其中，DwPTS可以传输下行导频、下行业务数据和下行控制信令；GP不传输任何信号；UpPTS仅传输随机接入和探测参考信号(SRS，Sounding Reference Symbol)，不能传输上行业务或上行控制信息。每个半帧中包含至少1个下行子帧和至少1个上行子帧，以及至多1个特殊子帧。FS2中执行的7种上下行子帧配置方式如表1所示。

LTE系统的用户平面(User Plane，简称U平面)时延由基站处理时间、帧对齐时间、传输时间间隔(TTI，Transmission Time Interval)时间和终端处理时间四部分构成，其中帧对齐时间为业务到达至业务能够获得空口子帧传输机会之间的等待时间。
以LTE-FDD下行传输为例，由于FDD系统每个子帧均有下行传输机会，帧对齐时间平均为0.5ms。基站处理时间在下行方向时为1ms，上行方向时为1.5ms；终端处理时间在上行方向时为1ms，下行方向时为1.5ms。因此，在不考虑Hybrid Automatic Repeat reQuest HARQ(混合自动重传请求)重传情况下，LTE-FDD下行U平面时延＝基站处理时间1ms+帧对齐时间0.5ms+TTI时间1ms+终端处理时间1.5ms，共4ms。相似的，LTE-FDD系统不考虑HARQ重传情况下的上行U平面延时也为4ms。如图3所示。
对于LTE-TDD系统，基站和终端处理时间以及TTI长度同FDD，如图4和图5所示。帧对齐时间与业务到达的时间和系统所使用的上下行配置有关。以上下行配置#5为例，基站若在子帧#1中完成发送端处理，则最早到子帧#3才能进行发送，则发射到空口子帧的帧对齐时间平均为1.5ms，其余子帧的帧对齐时间平均为0.5ms，故下行数据的平均对齐处理时间为(1.5+8*0.5)/9＝0.6ms。在不考虑HARQ重传情况下，表2和表3分别给出了各TDD上下行配置对应的DL(上行)和UL(下行)U平面时延的平均值。

表3
Figure PCTCN2017070938-appb-000003
上述U平面时延的计算中，基站和终端的处理时间、帧对齐时间都是与TTI长度相关的，如果TTI长度缩短，则U平面的总时延将会缩短。在现有的LTE帧结构基础上，可以考虑缩短TTI为0.5ms甚至于更小，即一个TTI长度为现有LTE帧结构中的一个时隙所包含的符号数，例如常规Cyclic Prefix CP时为7个符号，扩展CP时为6个符号；还可以进一步缩短TTI为小于1个时隙的长度，例如一个或几个符号。
在LTE系统中，现有的信道传输都是以TTI＝1ms来定义的，即一个TTI即为一个子帧，长度为1ms。UE需要传输上行数据时，将在下行子帧中检测上行调度许可(UpLink grant，简称UL grant)，该UL grant使用预定的下行控制信令(DCI，Downlink Control Information)格式(format)传输，用于通知终端进行上行传输的资源、调制编码(MCS，Modulation and Coding Scheme)等级、冗余版本、发射功率控制(TPC，Transmit Power Control)命令等传输参数，且UL grant与其调度的用于承载上行数据的物理上行共享信道(PUSCH，Physical Uplink Shared CHannel)采用固定的调度时序关系，即在子帧n中发送的UL grant用于调度在子帧n+k中传输的PUSCH，其中k对于FDD固定为4，对于TDD取决于不同的TDD上下行配置。
当采用非1ms的TTI长度时，数据和调度信令都不是以子帧为单位传输了，且可能支持更为灵活的上行和下行传输时间段分配，不同子帧中可能所包含的上行和下行传输时间段长度都会随着相应业务量而发生变化，在一个上行传输时间内，业务传输所使用的TTI长度也可以根据传输需求而动态变化，此时固定的调度时序就不适用了，数据如何传输目前尚无明确方案。
随着移动通信业务需求的发展变化，多个组织对未来移动通信系统都定义了更高的用户面延时性能要求。缩短用户时延性能的主要方法之一是降低TTI长度。当TTI缩短后，如何进行数据传输还没有明确方法。

具体的，目标时间单元可以是当前发送上行调度许可的第一时间单元，例如当发送上行调度许可的时域资源在该第一时间单元中在时间上比较靠前，而被调度的上行传输资源区域在该第一时间单元中在时间上比较靠后时，例如以一个子帧为一个时间单元为例，在子帧n中的第一个符号上发送上行调度许可，而该子帧n中的最后3个符号，即第12、13、14个符号为上行传输资源区域，则终端在第一个符号上检测上行调度许可后，有足够的时间解析处理该上行调度许可，从而获得其在最后3个符号上的调度信息，则该终端可以根据该调度信息，在最后3个符号上的被调度的时频域资源上进行上行传输；目标时间单元还可以是第一时间单元之后的第一个时间单元(假设该时间单元中存在上行传输)或第k个时间单元(假设该时间单元中存在上行传输)，k为大于或等于1的整数，例如当发送上行调度许可的时域资源与被调度的上行传输资源区域在同一个时间单元n中的符号间隔不够多，没有足够处理时间，例如以一个子帧为一个时间单元为例，在子帧n中的第一个符号上发送上行调度许可，而该子帧n中的第3个符号开始即为上行传输资源区域，则终端在第一个符号上检测上行调度许可后，没有足够的时间解析处理该上行调度许可，无法在第3个符号获得调度信息，因此，此时该上行调度许可可以调度终端在子帧n+1或者更靠后的子帧中的上行传输资源区域中进行上行传输；为了满足不同的上下行资源划分情况，可以总是保守的约定目标时间单元为时间单元n之后的第一个时间单元，此时隐含的需要保证该时间单元中必须有上行传输资源，或者，可以通过信令半静态的根据上下行传输资源的划分情况来配置目标时间单元的位置；此外，目标时间单元还可以为第一时间单元开始或者所述第一时间单元之后的满足上行调度许可处理时延的第一个包含上行传输资源的时间单元，即目标时间单元不是固定的，而是根据实际情况动态确定的，例如所述当处理时延满足在当前时间单元n中可以调度其所包含的上行传输资源时，目标时间单元即为当前时间单元n，否则继续向时间单元n之后的时间单元推移，直到找到满足处理时延且包含上行传输资源的时间单元，即为目标时间单元，由于每个时间单元中的上行 传输和下行传输资源的分配可以是相对动态的，可能一个传输时间单元中并不包含上行传输资源，则需要继续往后推移，需要找到满足处理时延且必须包含上行传输资源的时间单元。
具体的，本公开的第一实施例中所指的终端具体为需要进行上行传输的终端，步骤11中，目标终端检测上行调度许可时可多个目标终端同时进行检索，并分别解析得到的上行调度许可，从而获取各自的调度信息。需要说明的是，由于一个上行调度许可中可携带一个或者多个终端的调度信息，故通过终端标识(即UE ID)与来标识不同终端的调度信息。一般的，当一个上行调度许可调度多个终端时，这多个终端共享相同的时频域资源进行上行传输，通过空间信道的正交性即Multi-User Multiple-Input Multiple-Output MU-MIMO方式区分各自的传输信息。调度信息具体为指示目标终端在目标时间单元中进行上行传输的时域和频域资源大小和位置，例如时域上占用几个符号，频域上占用多少带宽(如多少个Single Carrier SC或多少个资源单元RU，RU被定义为在时域上占用X1个符号、频域上占用X2个子载波的资源区域，所述X2个子载波在频域上连续或不连续，X1和X2均为大于等于1的整数)，还可以包括调制编码信息、功率控制信息等。
终端解析检测到的上行调度许可得到自身的调度信息后，根据所述调度信息在对应的资源上传输上行信息。
进一步的，由于基站一次会在同一个目标时间单元中调度多个终端在不同的资源上进行上行传输，则就会在第一时间单元中发送多个上行调度许可，故终端检测到的上行调度许可中可能包含该目标终端的调度信息，也可能不包含该目标终端的调度信息，故本公开的第一实施例中步骤12包括：步骤121，解析所述上行调度许可的附带信息，确定所述上行调度许可是否包含所述终端的调度信息；步骤122，若所述上行调度许可包含所述终端的调度信息，从所述上行调度许可中获取所述终端在所述目标时间单元中的调度信息。
具体的，附带信息可以为上行调度许可中的预设信息域，所述预设信息域用于指示所述上行调度许可所调度的终端标识，当所述上行调度许可调度多个终端时，所述预设信息域中包括多个被调度终端的标识；此时，终端在检测到一个上行调度许可时，需要进一步解析其中的预设信息域，读取终端 标识，如果读取到与自身一致的终端标识，则说明该上行调度许可中包含自身的调度信息，可以进一步读取自身的调度信息，否则，说明不包含，继续检测下一个上行调度许可，重复上述方式判断是否包含自身调度信息。如果该上行调度许可调度一组终端，则其预设信息域中包含该组终端的标识信息。
具体的，附带信息还可以是上行调度许可的加扰信息。此时，终端在检测到一个上行调度许可时，需要进一步解析其加扰信息。例如使用与终端标识相对应的加扰序列进行相应的解扰。如果正确，则说明该上行调度许可包含该终端的调度信息，可以进一步读取自身的调度信息。否则，说明不包含，继续检测下一个上行调度许可，重复上述方式判断是否包含自身调度信息。如果该上行调度许可调度一组终端，则其加扰序列是对应该组终端的序列，具体对应关系为预先约定或者配置的。
具体的，附带信息还可以为在上行调度许可之前附带的第一预设序列，所述第一预设序列与终端标识相对应，且对应关系为预先约定或者预先配置的，不同序列之间相互正交。此时，终端在检测上行调度许可之前，先检测第一预设序列，如果检测到与自身对应的第一预设序列，再进一步检测并解析与在该序列之后的上行调度许可，可直接认为该许可中包含自身的调度信息。或者进一步通过上述读取预设信息域或识别加扰序列的方式判断该上行调度许可是否包含自身调度信息。如果没有检测到第一预设序列，则跳过该搜索部分不做上行调度许可的检测。当划分了多个搜索部分时，可以继续在下一个搜索部分重复上述进行检测。此时，附带信息相当于是用于指示目标终端的分组情况，协助目标终端判断当前上行调度许可是否包含该目标终端的调度信息。该种情况下，目标终端需要预先知道自己的分组状态，以便于判断自己所在分组的调度信息是否保存于其检测到的上行调度许可，减少终端对上行调度许可的盲检，提高检测效率。需要说明的是，将目标终端按照一定规则进行分组仅为本公开的一较佳实施例，不限于此形式，其他的指示信息也同样适用于本公开。
进一步的，为了更清楚的描述本公开的第一实施例，所述目标时域资源为所述第一时间单元中的预设符号位置，所述预设符号位置包括一个或多个符号。
具体的，所述预设符号位置为第a个或倒数第a个符号，a为大于或等于1的整数；或者所述预设符号位置为第a个符号或倒数第a个符号开始的连续K1个符号，a为大于或等于1的整数，K1为大于或等于1的整数。
当所述第一时间单元中包含1个下行传输资源区域时，所述预设符号位置为所述下行传输资源区域中的第一个或最后一个符号；或者所述预设符号位置为所述下行传输资源区域中的第一个符号开始的连续K1个符号或最后K1个符号，K1为大于或等于1的整数。
当所述第一时间单元中包含多个下行传输资源区域时，所述预设符号位置为第一个或最后一个下行传输资源区域中的第一个或最后一个符号，或第一个或最后一个下行传输资源区域中的第一个符号开始的连续K1个符号或最后K1个符号，K1为大于或等于1的整数。
其中，所述下行传输资源区域为所述第一时间单元中的预先划分的用于下行传输的资源区域。其中，一个时间单元中可以包括一个或者多个下行传输资源区域，每个区域在时域上为连续的P个符号、频域上占用全部或者部分系统带宽，多个区域之间不连续；该下行传输资源区域的换分是预先通知给终端的，不同时间单元中的划分可以相同或者不同。
综上，所述目标时域资源为时间单元n中的第a个或倒数第a个符号，a为大于或等于1的整数。可选地，所述目标时域资源为时间单元n中的第a个符号或倒数第a个符号开始的连续K1个符号，K1为大于或等于1的整数。可选地，当时间单元n中包含多个下行传输资源区域时，所述目标时域资源为时间单元n中的第一个或最后一个下行传输资源区域中的第一个或最后一个符号，或第一个或最后一个下行传输资源区域中的第一个符号开始的连续K1个符号或最后K1个符号，K1为大于或等于1的整数。可选地，当时间单元n中仅包含1个下行传输资源区域时，所述目标时域资源为时间单元n中的下行传输资源区域中的第一个或最后一个符号，或时间单元n中的下行传输资源区域中的第一个符号开始的连续K1个符号或最后K1个符号，K1为大于或等于1的整数。
具体的，所述目标频域资源为频域上的预设子载波位置或者预设资源单元位置。所述预设子载波位置包括一个或多个子载波。所述预设资源单元位 置包括一个或多个资源单元。其中，所述资源单元为在时域上占用X1个符号、频域上占用X2个子载波的资源区域，所述X2个子载波在频域上连续或不连续，X1和X2均为大于等于1的整数。
可选地，所述目标频域资源在频域上连续；或者所述目标频域资源在频域上按照预定颗粒度均匀分布在系统带宽内或下行传输所对应的带宽内；或者所述目标频域资源在频域上分布在系统带宽内或下行传输所对应的带宽内的最高频位置或最低频位置或中心频域位置。
进一步的，所述目标时域资源和/或所述目标频域资源为预先约定的1个或多个资源；或者为高层信令/广播信息等信令通知的1个资源，该资源为在预先定义的多个资源中选择的一个资源。当为多个资源时，终端需要在多个资源上检测UL grant，并根据UL grant中的特定信息域或UL grant加扰方式或在UL grant之前发送的特定序列确定该UL grant是否为该终端的。基站则自主选择在其中一个位置发送一个或一组终端的UL grant，在另一个位置发送另一个或一组终端的UL grant，在此不具体限定其基站的发送UL grant的位置。当系统中定义的可以传输UL grant的资源较多时，为了减少终端盲检UL grant的次数及时间，可以预先配置或者通知一个或有限几个目标时域资源和目标频域资源。则目标终端可直接在确定的一个或有限的几个目标时域资源和目标频域资源上进行UL grant的检索。具体的其交互包括：网络侧通过高层信令/广播信息通知目标终端，在此不进行具体限定。
进一步的，本公开的第一实施例中，所述上行传输方法还包括：在所述目标时间单元中的被调度的时域资源和频域资源上进行上行传输时携带第二预设序列，所述第二预设序列与所述终端的标识相关，使得其他终端和/或基站能够根据所述第二预设序列对所述终端进行干扰测量。

综上，本公开的第一实施例对目标终端侧的上行传输方法进行详细描述，具体为在一个时间单元中的特定时域和频域资源上检测UL grant，所述UL grant用于调度特定时间单元中的上行传输资源区域中的上行传输；K大于或者等于1。该上行传输方法便于网络侧对终端协调调度，减少终端对上行调度信令的盲检，提高传输效率。

下面结合几个具体的例子对本公开的上行传输方法进行描述。
第一例
以1ms(即一个LTE子帧)为一个时间单元，一个时间单元中发送的UL grant用于调度该时间单元中的上行传输时间段上的上行传输，约定或配置在一个时间单元中第一个符号上的特定频域位置(例如中间或低频或高频频域位置上的K2个SC或RE或RU，或分散在下行传输带宽内的K2个SC或RE或RU)上传输UL grant。如图8所示，基站在一个时间单元中的第一个符号上的特定频域位置发送了UL grant，期待在该时间单元中进行上行传输的每个目标终端，则在该时间单元中的第一个符号上的特定频域位置检测UL grant，得到该UL grant之后，进一步解析该UL grant，根据其中用于标识终端的比特域，获取该终端对应的调度信息，从而在被调度的时频域资源上进行上行传输。
第二例
以1ms(即一个LTE子帧)为一个时间单元，一个时间单元中发送的UL grant用于调度下一个时间单元中的上行传输时间段上的上行传输，约定或配置在一个时间单元中第一个符号上的特定频域位置(例如中间或低频或高频频域位置上的K2个SC或RE或RU，或分散在下行传输带宽内的K2个SC 或RE或RU)上传输UL grant。如图9所示，基站在一个时间单元中的第一个符号上的特定频域位置发送了UL grant，期待在下一个时间单元中进行上行传输的每个目标终端，则在当前时间单元中的第一个符号上的特定频域位置检测UL grant，得到该UL grant之后，进一步解析该UL grant，根据其中用于标识终端的比特域，获取该终端对应的调度信息，从而在下一个时间单元中的被调度的时频域资源上进行上行传输。
第三例
以1ms(即一个LTE子帧)为一个时间单元，一个时间单元中发送的UL grant用于调度下一个时间单元中的上行传输时间段上的上行传输，约定或配置在一个时间单元中最后一个符号上或最后一个下行传输时间段内的最后一个符号上的特定频域位置(例如中间或低频或高频频域位置上的K2个SC或RE或RU，或分散在下行传输带宽内的K2个SC或RE或RU)上传输UL grant。如图10所示，基站在一个时间单元中的最后一个符号上的特定频域位置发送了UL grant，期待在下一个时间单元中进行上行传输的每个终端，则在当前时间单元中的最后一个符号上的特定频域位置检测UL grant，得到该UL grant之后，进一步解析该UL grant，根据其中用于标识终端的比特域，获取该终端对应的调度信息，从而在下一个时间单元中的被调度的时频域资源上进行上行传输。
第四例
以1ms(即一个LTE子帧)为一个时间单元，一个时间单元中发送的UL grant用于调度下一个时间单元中的上行传输时间段上的上行传输，包括所有在该上行传输资源上进行传输的终端的上行传输，约定或配置在一个interval中最后一个下行传输时间段内的第一个符号上的特定频域位置(例如中间或低频或高频频域位置上的K2个SC或RE或RU，或分散在下行传输带宽内的K2个SC或RE或RU)上传输UL grant。如图11所示，基站在一个interval中最后一个下行传输时间段内的第一个符号上的特定频域位置发送了UL grant，期待在下一个时间单元中进行上行传输的每个终端，则在当前时间单元中最后一个下行传输时间段内的第一个符号上的特定频域位置检测UL grant，得到该UL grant之后，进一步解析该UL grant，根据其中用于标识终 端的比特域，获取该终端对应的调度信息，从而在下一个时间单元中的被调度的时频域资源上进行上行传输。
上述实例中，如果在一个时间单元中的被调度终端数量较多，而被调度的上行传输资源不足够支持每个终端在独立的时频域资源上进行上行传输，还可以预先对终端进行分组。一个终端组中的终端的调度信息在一个UL grant中发送，不同终端组的调度信息在不同的UL grant中发送，不同UL grant通过其中的终端标识域或者附加序列或者加扰序列来区分与终端组的对应关系。终端侧通过盲检端标识域或附加信息或加扰序列来确定哪个UL grant包含自身的调度信息，具体实现方式与上述过程类似，不再赘述。
进一步，如果终端传输上行信息的同时还携带发送特定序列，该序列可以被该终端所在小区A中的其他终端检测到，用于辅助与该终端的传输同步，从而进一步进行终端间通信。该序列还可以被邻小区中的终端和/或基站检测到，用于识别该小区A中哪些终端在哪些资源上存在上行信息传输，并进一步通过该序列测量得到信号能力大小，从而得到小区A中的终端相对于自身的干扰大小，为其后续针对该终端的上行数据对其的干扰做干扰协调和干扰消除提供先验信息。
综上，本公开实施例给出一种在一个时间单元中的特定位置传输UL grant，用来集中调度当前或者后续一个时间单元中的所有终端进行上行传输的方法，便于网络侧对终端协调调度，减少终端对上行调度信令的盲检，提高传输效率。
