Description

确定保护时隙的方法及设备、终端、存储介质 技术领域
本发明涉及子帧配置技术，尤其涉及一种确定保护时隙的方法及设备、终端、存储介质。
背景技术
第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)长期演进(LTE，Long Term Evolution)系统及其增强LTE(LTE-Advanced)可基于两种制式工作：一种是频分双工(Frequency Division Duplexing，FDD)制式(FDD LTE)，如图1所示，对应帧结构类型1，即下行传输和上行传输承载于成对的频谱(两个不同频带)，下行和上行传输频分双工，从而避免相互之间的频带干扰；另一种是时分双工(Time Division Duplexing，TDD)制式(TD-LTE)，如图2所示，对应帧结构类型2，即下行传输和上行传输承载于同一频点，下行和上行传输同频时分双工，从而避免相互之间的时隙干扰。
随着通信技术的发展，不断地有新的帧结构被提出，例如将TDD和FDD的帧结构进行融合，这种融合的新型的帧结构被提广泛讨论，如下图3所示，在一个子帧中，既包含用于下行传输的下行时隙，也包含用于上行传输的上行时隙，还包括位于上行时隙与下行时隙中间的保护时隙。这种帧结构类似于特殊时隙的配置，但是上下行的持续时间长度可以灵活地配置。另一方面，随着通信技术的发展，未来低时延业务的涌现可能会导致符号的持续时间进一步缩短。
在LTE的特殊子帧中，UpPTS并不用于传输物理上行共享信道(PUSCH，Physical Uplink Shared Channel)数据，而是用来传输物理随机接入信道 (Physical Random Access Channel，PRACH)数据和/或信道探测参考信号(SRS，Sounding Reference Signal)。对于覆盖距离大的小区来说，需要设置为GP时长大的特殊子帧配置，由于UpPTS不用于传输业务数据，因此对于UpPTS区域最多支持2个基本符号(symbol)的配置不会带来上行容量的损失；而在未来的帧结构设计中，考虑到业务种类的多样性，基本符号持续时间长度缩短的情况下，对于覆盖半径大的小区的情况，如果所有UE都需要保持一个大的GP，那么会造成资源的浪费。

具体实施方式
一般来说，LTE系统采用等长的子帧(Sub-frame)结构，例如：每个子帧为1毫秒(ms)，即每个子帧包含两个0.5ms的时隙；10个子帧构成10ms的无线帧(Radio Frame)。与LTE FDD的不同在于，TD-LTE还引入了特殊子帧。特殊子帧由下行导频时隙(DwPTS，Downlink Pilot Time Slot)、保护时隙(GP，Guard Period)和上行导频时隙(UpPTS，Uplink Pilot Time Slot)三部分组成。如图2中标记为S的子帧是下行子帧和上行子帧的过渡子帧。GP用于完成下行到上行的转换，GP的大小与小区覆盖距离有关，其中，小区覆盖距离越大，GP也越大；小区覆盖距离越小，GP也越小。GP的值主要由传输时延和用户设备收发转换时延决定，参见式(0-1)：
GP＝2×传输时延+TRX->Tx   (0-1)；
在式(0-1)中，传输时延为小区覆盖距离光速传播所需要的时间，TRX->Tx是用户设备(UE，User Equipment，又称为终端)从下行接收到上行发送的转换时间，通常是与用户设备的硬件相关的固定的取值。
在LTE系统中，支持多种特殊时隙配置，分别对应不同的DwPTS、GP、UpPTS取值。如下表1所示，特殊子帧的配置通过系统消息(系统信息块(SIB消息)广播给所有UE，所有的UE统一按照基站广播的配置确定特殊子帧DwPTS、GP、UpPTS的持续时长。不同的GP长度可对应不同的小区覆盖距离。在表1中，CP表示循环前缀(Cyclic Prefix，CP)。

在本发明以下的实施例中，用户设备接入小区时，读取到的是小区专属(cell specific)的GP的时间长度配置；之后基站根据用于表征用户设备的位置的信息，例如基于用户设备的位置信息或时间提前量(TA，Timing Advance)信息等，为UE配置UE专属的GP长度；基站基于UE专属的GP长度动态地调整子帧中上行或下行业务的持续时长；基站将配置的业务的持续时长或者GP的长度通知给UE；UE根据基站的配置进行相应的上下行的传输。
下面结合附图和具体实施例对本发明的技术方案进一步详细阐述。
实施例一
为了解决前述的实施例，本发明实施例提供一种确定保护时隙的方法，该方法应用于网络侧，例如网络设备(基站)，该方法所实现的功能可以通过网络设备中的处理器调用程序代码来实现，当然程序代码可以保存在计 算机存储介质中，可见，该网络设备至少包括处理器和存储介质。
图4为本发明实施例一确定保护时隙的方法的实现流程示意图，如图4所示，该方法包括：
步骤S401，网络侧根据用于表征用户设备UE的位置的信息为所述UE确定GP的时间长度；
步骤S402，所述网络侧基于所述UE的GP的时间长度确定子帧中上行或下行业务的持续时长；
步骤S403，所述网络侧将以下信息至少之一通知给所述UE：所述上行业务的持续时长、所述下行业务的持续时长、所述GP的时间长度。
在本发明其他实施例中，所述网络侧基于所述UE的GP的时间长度确定子帧中上行或下行业务的持续时长，包括：所述网络侧基于所述UE的GP的时间长度确定子帧中上行时隙的时间长度或下行时隙的时间长度；对应地，所述网络侧将所述上行时隙的时间长度或下行时隙的时间长度或者所述GP的时间长度通知给所述UE。
这里，所述网络侧基于所述UE的GP的时间长度确定子帧中上行时隙的时间长度或下行时隙的时间长度，包括：所述网络侧确定下行时隙的时间长度相同且下行时隙的时序对齐；所述网络侧根据所述GP的时间长度、子帧的总时间长度、下行时隙的时间长度确定上行时隙的时间长度。
这里，所述网络侧基于所述UE的GP的时间长度确定子帧中上行时隙的时间长度或下行时隙的时间长度，包括：所述网络侧确定上行时隙的时间长度相同且上行时隙的时序对齐；所述网络侧根据所述GP的时间长度、子帧的总时间长度、上行时隙的时间长度确定下行时隙的时间长度。
在本发明其他实施例中，所述网络侧根据用于表征所述UE的位置的信息为所述UE确定GP的时间长度，包括：所述网络侧根据所述UE的位置信息或时间提前量信息或测量反馈信息确定所述GP的时间长度。
在本发明其他实施例中，所述GP的时间长度采用持续符号个数来或比 例来表示。这里，所述方法还包括：根据通信标准确定所述比例或者根据自定义的规则确定所述比例。
在本发明其他实施例中，所述网络侧将以下信息至少之一通知给所述UE，包括：
所述网络侧通过控制信道中增加N比特动态指示，所述N比特用于携带以下信息至少之一：所述上行业务的持续时长、所述下行业务的持续时长、所述GP的时间长度；或者，所述网络侧通过半静态信令指示给UE，所述半静态信令中携带以下信息至少之一：所述上行业务的持续时长、所述下行业务的持续时长、所述GP的时间长度。
本发明实施例中：网络侧根据用于表征UE的位置的信息为所述UE确定GP的时间长度；所述网络侧基于所述UE的GP的时间长度确定子帧中上行或下行业务的持续时长；所述网络侧将以下信息至少之一通知给所述UE：所述上行业务的持续时长、所述下行业务的持续时长、所述GP的时间长度；如此，能够动态地调整上行或者下行传输的持续时长，从而达到资源的充分利用，进而避免资源浪费。
实施例二
在本发明实施例中，保持子帧的下行时序对齐，根据GP的长度动态调整上行时序。例如，在子帧中被调度下行传输的UE保持下行传输在时序上的对齐，而上行传输在基站端看到的是不对齐的，不同的UE的上行传输持续的时间长度则不同，根据基站为UE配置的GP的长度预留出相应GP长度，从而能够实现资源更有效的利用。
下面举例来说明，如图5所示，5个UE(UE1至UE5)的下行传输的时序的两端都是对齐的，因为下行传输的时间长度是相同的；而UE1至UE5的GP的时序在一端是对齐的，由于UE1至UE5的GP的时间长度是不一样的，所以UE1至UE5的CP的时序在另一端不是对齐的。对于上行传输， 上行传输的时序在一端是对齐的，由于上行传输的时间长度各不相同，所以上行传输的时序在另一端不是对齐的。从以上描述可以看出，根据基站为UE1至UE5配置的GP的长度预留出相应GP长度，从而能够实现资源更有效的利用。
下面基于图5所示的实施例，来提供一种确定保护时隙的方法，该方法包括：
步骤S501，UE在接入小区时从网络侧获取一个广播的保护时隙长度；
这里，在UE接入小区时，网络侧向UE发送保护时隙长度，在实现的过程中可以通过广播消息来实现，需要说明的是，在步骤S501中的所述广播的保护时隙长度实际上是一个由基站配置的作为一个默认的保护时隙长度。UE接收到广播的保护时隙后，如果UE不想对保护时隙长度更改的话，那么就可以采用默认的保护时隙长度。如果UE想对保护时隙长度更改的话，那么即可以进入步骤S502。需要说明的是，是否对保护时隙长度做出更改可以根据设置的规则来确定，或者根据UE的上行业务来确定。
这里，保护时隙的长度可以采用持续符号个数来描述，也可以采用比例(又称为配比)来描述，因为上行时隙、下行时隙和GP组成的子帧的总的时间长度是固定的。在实施的过程中，所述网络侧可以包括基站，当然对于本领域的技术人员来说，网络侧还可以采用其他的网元来实现，这里不再赘述。下面以保护时隙的长度采用配比来举例，该配比可以由基站确定，例如，基站可以基于最大的GP需求来确定保护时隙的长度，例如基站根据小区覆盖距离确定保护时隙的长度。
步骤S502，网络侧根据UE的位置信息，判断出UE需要预留的保护时隙大小；
这里，UE的位置信息不一定是精确的位置信息，UE的位置信息可以采用UE的测量反馈信息或者UE的时间提前量(TA)信息，因此，网络侧可以基于UE的测量反馈信息来确定预留的保护时隙的大小等，网络侧也 可以利用现有的TA确定方法确定出TA的值，从而判断出UE当前位置所需要的GP的大小。
这里，所述测量反馈信息可以是UE测量上行导频和下行导频的信息。
步骤S503，网络侧为UE配置GP时长或者下行、GP、上行三者的比例；
这里，GP时长可以以符号个数等为计量；下行、GP、上行配比可以来自现有的LTE的配比，也可以是新定义的配比。
步骤S504，网络侧通过下发信令指示给UE其GP时长或者下行、GP、上行三者的比例。
在实现的过程中，通过控制信道中增加N比特动态指示；或者，通过半静态信令如RRC信令指示给UE。
步骤S505，UE在上行传输时按照网络侧的配置实时确定上行传输时域持续时长。
这里，所述UE在接入小区后，所述终端侧接收所述网络侧发送的以下信息至少之一：上行业务的持续时长、GP的时间长度；所述UE根据所述信息确定用于发送上行业务的上行时隙的持续时长；所述终端侧根据所述上行业务的持续时长发送上行业务。
本发明实施例中，针对每一UE，网络侧根据UE对保护时隙长度的需求，动态地调整每个UE的保护时隙长度，因此，对于小区内不同的UE可以采用不同的保护时隙长度。
实施例三
在本发明实施例中，保持子帧的上行时序对齐，根据所调度频域位置对应的上行调度用户设备的GP的长度动态调整下行的调度时长(时间长度)。例如，在子帧中上行传输在时序上的对齐，而下行传输是不对齐的，不同的UE的下行传输持续的时间长度则不同，根据基站为UE配置的GP 的长度预留出相应GP长度，从而能够实现资源更有效的利用。
下面举例来说明，如图6所示，4个UE(UE1至UE4)的上行传输的时序的两端都是对齐的，因为上行传输的时间长度是相同的；而UE1至UE4的GP的时序在一端是对齐的，由于UE1至UE4的GP的时间长度是不一样的，所以UE1至UE4的CP的时序在另一端不是对齐的。对于下行传输，下行传输的时序在一端是对齐的，由于下行传输的时间长度各不相同，所以下行传输的时序在另一端不是对齐的。从以上描述可以看出，根据基站为UE1至UE4配置的GP的长度预留出相应GP长度，从而调整下行的调度时长，进而能够实现资源更有效的利用。
下面基于图6所示的实施例，来提供一种确定保护时隙的方法，该方法包括：
步骤S601，UE在接入小区时从网络侧获取一个广播的保护时隙长度；
这里，所述步骤S601请参见步骤S501。
这里，保护时隙的长度可以采用持续符号个数来描述，也可以采用比例(又称为配比)来描述，因为上行时隙、下行时隙和GP组成的子帧的总的时间长度是固定的。在实施的过程中，所述网络侧可以包括基站，当然对于本领域的技术人员来说，网络侧还可以采用其他的网元来实现，这里不再赘述。下面以保护时隙的长度采用配比来举例，该配比可以由基站确定，例如，基站可以基于最大的GP需求来确定保护时隙的长度，例如基站根据小区覆盖距离确定保护时隙的长度。
步骤S602，网络侧根据需要在当前子帧进行上行调度的UE的信息，先对上行UE进行物理资源调度分配；
步骤S603，网络侧根据当前子帧中被调度了上行传输UE的位置信息，判断出需要为这些上行UE预留的保护时隙大小；
这里，UE的位置信息不一定是精确的位置信息，UE的位置信息可以采用UE的测量反馈信息或者UE时间提前量(TA)信息，因此，网络侧 可以基于UE的测量反馈信息来确定预留的保护时隙的大小等，网络侧也可以利用现有的TA确定方法确定出TA的值，从而判断出UE当前位置所需要的GP的大小。
步骤S604，网络侧在调度当前子帧的下行数据时，根据相同频带上已经调度的上行UE对GP的要求确定下行UE的持续符号个数；
这里，所述对GP的要求即为网络侧为GP预留的时间长度大小。
这里，下行可以是任意个数的持续符号个数，也可以对应某些配比；当相同频带对应多个上行用户设备的调度时，按照GP时隙的长度要求最大的那个上行UE的GP长度为准。
步骤S605，网络侧通过信令指示给下行UE其时域持续时长；
这里，在实现的过程中，可以通过下行控制信息中增加N比特指示来实现，例如这N比特用于指示几种配置中的一种，或者指示时域持续符号个数。由于下行UE在子帧内的持续时长(时间长度)取决于相同频带调度的上行用户设备的情况，而每个子帧对应的上行子帧的调度情况可能不同，因此动态的指示在下行时长可变的情况下，更适用。
步骤S606，UE在下行传输时，按照网络侧的配置确定当前子帧传输时域持续时长以接收基站发送的下行业务。
这里，所述UE在接入小区后，终端侧在接入小区后，所述UE接收所述网络侧发送的以下信息至少之一：上下行业务的持续时长、GP的时间长度；所述UE根据所述信息确定用于接收下行业务的持续时长；所述UE根据下行业务的持续时长接收下行业务。
在实施例一中上行时隙的时间长度可变，在实施例二中下行时隙的时间长度可变，至于是上行时隙的时间长度可变还是下行时隙的时间长度可变，可以由基站进行广播通知或者根据子帧的传输情况决定，例如当前子帧的上行时隙只传输控制信息和测量信息相关的内容，而业务信息只有下行的传输，则可以固定为保持上行时隙的时序对齐，下行时隙的时间长度 根据GP的时间长度进行动态调整；相反地，如果当前子帧为上行业务信道传输模式，即下行传输中只包含下行控制信息等而不包含业务信息，则可以采用保持下行时隙的时间长度固定，上行时隙的时间长度根据GP的时间长度进行动态调整。
在本发明以上的实施例中，基站根据用户设备的位置信息，例如基于用户设备的TA信息等，为UE配置UE专属的GP长度。基站基于UE专属的GP长度，动态的调整子帧中上行或下行业务的持续时长。基站将配置的业务的持续时长或者GP的长度通知给UE；UE根据基站的配置，进行相应的上下行的传输。
与现有技术相比，本发明实施例具有如下的优点：根据UE的位置信息，确定调度用户设备进行上行传输时需要预留的GP长度，从而动态的调整上行或者下行传输的持续时长，达到资源的充分利用，避免资源浪费。
