一种发送上行信息的方法及装置 技术领域
本发明涉及通信技术领域,尤其涉及一种发送上行信息的方法及装置。
背景技术
现有技术中,当UE(User Equipment,用户设备)处于RRC(Radio Resource Control,无线资源控制)连接状态,并且上行失步后,UE会释放分配的上行资源,如PUCCH(Physical Uplink Control Channel,物理上行控制信道)资源、SRS(Sounding Reference Signal,探测参考信号)资源、半静态的PUSCH(Physical Uplink Shared Channel,物理上行共享信道)资源等。UE在上行失步后,除了会给网络侧发送随机接入码之外,不会向网络侧发送任何其他信息,例如,不会发送上行数据;又例如,即使接收到网络侧发送的下行数据,也不执行下行数据的上行HARQ(Hybrid Automatic Repeat Request,混合自动重传请求)反馈。
UE在上行失步后,要发送上行数据,或者进行上行HARQ反馈的话,要先进行随机接入过程,获得上行同步,然后,在上行同步后,再进行上行数据发送,或者上行HARQ反馈。
例如,有上行数据到达UE,由于UE已经上行失步,无法进行上行发送,因此,进行随机接入,完成随机接入后,UE获得上行同步,然后,才可以发送上行数据。同理,有下行数据到达网络侧后,由于UE已经上行失步,无法进行上行发送,即不能对下行数据进行反馈,因此,网络侧触发UE执行随机接入,完成随机接入后,UE获得上行同步,网络侧设备向UE发送下行数据,进而UE对接收到的下行数据进行上行HARQ反馈。
但是,目前UE进行上行同步过程较复杂,因此,存在发送上行数据,或者发送下行数据的上行HARQ反馈的时延较长、效率较低的缺陷。
发明内容
本发明实施例提供了一种发送上行信息的方法及装置,用于解决现有技术中存在的发送上行数据,或者发送下行数据的上行HARQ反馈的时延较长、效率较低的缺陷。

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。
下面结合说明书附图对本发明优选的实施方式进行详细说明,应当理解,此处所描述的优选实施例仅用于说明和解释本发明,并不用于限定本发明,并且在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互组合。
参阅图1A所示,提供一种用户设备,该用户设备包括确定模块10、调整模块11和发送模块12,其中:
确定模块10,用于确定调度信息和定时提前信息,调度信息用于指示用户设备发送上行信息,定时提前信息用于调整用户设备发送上行信息时采用的定时提前量;
调整模块11,用于根据定时提前信息调整定时提前量;
发送模块12,用于根据调度信息,采用调整后的定时提前量发送上行信息。
在该方案中,用户设备不需要通过随机接入过程来获得上行同步,即用户设备不需要通过发送随机接入码就可以确定定时提前信息,减少了用户设备和网络侧设备进行随机接入码的交互,因此,解决了现有技术中存在的发送上行数据,或者发送下行数据的上行HARQ反馈的时延较长、效率较低的 缺陷。
可选的,确定模块10确定调度信息和定时提前信息时,具体为:
确定模块10在第一TTI(Transmission Time Interval,传输时间间隔),确定调度信息和定时提前信息。
可选的,发送模块12根据调度信息,采用调整后的定时提前量发送上行信息时,具体为:
发送模块12根据调度信息,在第二TTI采用调整后的定时提前量发送上行信息;
第二TTI与第一TTI之间间隔N个TTI,N大于或者等于0。
由于用户设备根据该调度命令发送上行信息的时候,在第二TTI就可以采用调整后的定时提前量来发送,用户设备和网络侧设备实现了同步,进而可以使网络侧能准确接收到用户设备发送的调度信息。
由于定时提前信息是对定时提前量调整,因此,进一步的,确定模块10还用于,确定定时提前量。
这样,确定的定时提前信息才是有意义的,如果定时提前量没有确定的话,确定定时提前信息也是没有意义的。
进一步的,还包括接收模块13,用于接收MAC(Media Access Control,接入媒体控制)CE(Control Element,控制元素),或者接收物理层控制信令;
此时,确定模块10确定定时提前信息时,具体为:
确定模块10从MAC CE中获取定时提前信息;或者
用户设备从物理层控制信令中获取定时提前信息。
由于MAC CE里面包含6bit的调整值,因此,为了避免资源浪费,可以优先选择MAC CE携带定时提前信息。
进一步的,还包括接收模块13,用于接收物理层控制信令;
确定模块10确定调度信息时,具体为:
确定模块10从物理层控制信令中获取调度信息。
可选的,上行信息包括上行数据和/或上行HARQ(Hybrid Automatic  Repeat Request,混合自动重传请求)反馈信息。
也就是说,上行信息可以为上行数据,或者,当接收到下行数据时,需要对下行数据进行上行HARQ反馈,此时,上行信息也可以为上行HARQ反馈信息。
上行信息包括上行HARQ反馈信息;
在现有技术中,通常用户设备会在当前TTI接收到下行数据后,在之后的第四个TTI对接收到的下行数据进行上行HARQ反馈,进行上行HARQ反馈所使用的反馈资源通常是根据调度命令所占资源的位置获得的,但是,当用户设备在当前TTI之后的第六个TTI发送上行HARQ反馈信息时,可能与其它用户设备在N+2确定的N+6时刻所使用的反馈资源冲突,因此,为了避免反馈资源发生冲突,此时,确定模块10还用于,确定发送上行HARQ反馈信息时能够采用的反馈资源;
发送模块12根据调度信息,采用调整后的定时提前量发送上行信息时,具体为:
发送模块12根据调度信息,采用调整后的定时提前量,在反馈资源上发送上行信息。
这样,用户设备可以预先确定反馈资源,进而可以避免不同用户设备占用相同的反馈资源,避免了资源冲突。
可选的,确定模块10确定发送上行HARQ反馈信息时能够采用的反馈资源时,具体为:
确定模块10确定资源配置信息,将资源配置信息所对应的资源作为反馈资源。
可选的,资源配置信息包括时域信息、频域信息、码域信息中的至少一种。
为了使得用户设备能够灵活选择是通过本方案来获得上行同步,还是通过随机接入过程来获得上行同步,进一步的,还包括接收模块13,用于接收定时提前量调整指示,定时提前量调整指示用于指示用户设备,能够根据定 时提前信息调整定时提前量。
也就是说,接收模块13接收到定时提前量调整指示之后,才开启根据本方案实现上行同步的功能,如果没有接收到定时提前量调整指示的话,只能通过随机接入过程来实现上行同步。
由于本方案的前提是针对用户设备处于失步状态的场景来描述的,也就是说,本方案在这种场景下才有意义,如果用户设备处于同步状态下,网络侧设备能准确接收到用户设备的上行信息,不需要定时提前量,更不需要定时提前信息,因此,进一步的,确定模块10还用于,确定用户设备处于失步状态。
参阅图1B所示,本发明实施例提供一种用户设备,该用户设备包括处理器100、发射器110,其中:
处理器100,用于确定调度信息和定时提前信息,调度信息用于指示用户设备发送上行信息,定时提前信息用于调整用户设备发送上行信息时采用的定时提前量;
处理器100还用于,根据定时提前信息调整定时提前量;
发射器110,用于根据调度信息,采用调整后的定时提前量发送上行信息。
在该方案中,用户设备不需要通过随机接入过程来获得上行同步,即用户设备不需要通过发送随机接入码就可以确定定时提前信息,减少了用户设备和网络侧设备进行随机接入码的交互,因此,解决了现有技术中存在的发送上行数据,或者发送下行数据的上行HARQ反馈的时延较长、效率较低的缺陷。
可选的,处理器100确定调度信息和定时提前信息时,具体为:
处理器100在第一TTI(Transmission Time Interval,传输时间间隔),确定调度信息和定时提前信息。
可选的,发射器110根据调度信息,采用调整后的定时提前量发送上行信息时,具体为:
发射器110根据调度信息,在第二TTI采用调整后的定时提前量发送上 行信息;
第二TTI与第一TTI之间间隔N个TTI,N大于或者等于0。
由于用户设备根据该调度命令发送上行信息的时候,在第二TTI就可以采用调整后的定时提前量来发送,用户设备和网络侧设备实现了同步,进而可以使网络侧能准确接收到用户设备发送的调度信息。
由于定时提前信息是对定时提前量调整,因此,进一步的,处理器100还用于,确定定时提前量。
这样,确定的定时提前信息才是有意义的,如果定时提前量没有确定的话,确定定时提前信息也是没有意义的。
进一步的,还包括接收器120,用于接收MAC(Media Access Control,接入媒体控制)CE(Control Element,控制元素),或者接收物理层控制信令;
此时,处理器100确定定时提前信息时,具体为:
处理器100从MAC CE中获取定时提前信息;或者
用户设备从物理层控制信令中获取定时提前信息。
由于MAC CE里面包含6bit的调整值,因此,为了避免资源浪费,可以优先选择MAC CE携带定时提前信息。
进一步的,还包括接收器120,用于接收物理层控制信令;
处理器100确定调度信息时,具体为:

可选的,上行信息包括上行数据和/或上行HARQ(Hybrid Automatic Repeat Request,混合自动重传请求)反馈信息。
也就是说,上行信息可以为上行数据,或者,当接收到下行数据时,需要对下行数据进行上行HARQ反馈,此时,上行信息也可以为上行HARQ反馈信息。
上行信息包括上行HARQ反馈信息;
在现有技术中,通常用户设备会在当前TTI接收到下行数据后,在之后的第四个TTI对接收到的下行数据进行上行HARQ反馈,进行上行HARQ反 馈所使用的反馈资源通常是根据调度命令所占资源的位置获得的,但是,当用户设备在当前TTI之后的第六个TTI发送上行HARQ反馈信息时,可能与其它用户设备在N+2确定的N+6时刻所使用的反馈资源冲突,因此,为了避免反馈资源发生冲突,此时,处理器100还用于,确定发送上行HARQ反馈信息时能够采用的反馈资源;
发射器110根据调度信息,采用调整后的定时提前量发送上行信息时,具体为:
发射器110根据调度信息,采用调整后的定时提前量,在反馈资源上发送上行信息。

可选的,处理器100确定发送上行HARQ反馈信息时能够采用的反馈资源时,具体为:
处理器100确定资源配置信息,将资源配置信息所对应的资源作为反馈资源。
可选的,资源配置信息包括时域信息、频域信息、码域信息中的至少一种。

也就是说,接收器120接收到定时提前量调整指示之后,才开启根据本方案实现上行同步的功能,如果没有接收到定时提前量调整指示的话,只能通过随机接入过程来实现上行同步。
由于本方案的前提是针对用户设备处于失步状态的场景来描述的,也就是说,本方案在这种场景下才有意义,如果用户设备处于同步状态下,网络侧设备能准确接收到用户设备的上行信息,不需要定时提前量,更不需要定 时提前信息,因此,进一步的,处理器100还用于,确定用户设备处于失步状态。

在该方案中,用户设备不需要通过随机接入过程来获得上行同步,即用户设备不需要通过发送随机接入码就可以确定定时提前信息,也就是说,网络侧设备不需要在接收到随机接入码的时候才向用户设备发送定时提前信息,而是可以实时或者按照一定的周期发送,网络侧设备和用户设备减少了交互随机接入码的过程,因此,解决了现有技术中存在的发送上行数据,或者发送下行数据的上行HARQ反馈的时延较长、效率较低的缺陷。
可选的,发送模块20发送调度信息和定时提前信息时,具体为:
发送模块20在第一传输时间间隔TTI,发送调度信息和定时提前信息。
可选的,接收模块21接收上行信息时,具体为:

这样,用户设备可以预先确定反馈资源,进而可以避免不同用户设备占用相同的反馈资源,避免了资源冲突。
可选的,资源配置信息包括时域信息、频域信息、码域信息中的至少一种。
为了使得用户设备能够灵活选择是通过本方案来获得上行同步,还是通 过现有技术来获得上行同步,进一步的,发送模块20还用于,发送上行定时提前量调整指示,定时提前量调整指示用于指示用户设备,能够根据定时提前信息调整定时提前量。

基于上述方案,本发明实施例中,还提出一种上行信息的发送系统,该系统包括如图1A或者图1B所示的用户设备,及如图2A或者图2B所示的网络侧设备。
基于上述方案,本发明实施例中,还提出另一种上行信息的发送系统, 该系统包括如图3A或者图3B所示的用户设备,及如图4A或者图4B所示的网络侧设备。
基于上述方案,参阅图5A所示,本发明实施例中,上行数据发送的一种流程如下:
步骤500:用户设备确定调度信息和定时提前信息,调度信息用于指示用户设备发送上行信息,定时提前信息用于调整用户设备发送上行信息时采用的定时提前量;
步骤510:用户设备根据定时提前信息调整定时提前量;
步骤520:用户设备根据调度信息,采用调整后的定时提前量发送上行信息。
本发明实施例中,定时提前量用于调整上行信息到达网络侧设备的时间,调整的目的是用于满足网络侧的接收定时要求。
本发明实施例中,定时提前信息所指示的值可以为正值,此时,需要将定时提前量往前调整,定时提前信息所指示的值也可以为负值,此时,需要将定时提前量往后调整,但是,无论定时提前信息所指示的值是正值还是负值,调整后的定时提前量还是正值,也就是说,无论定时提前量根据定时提前信息怎样调整,都要保证用户设备发送的上行信息准确达到网络侧设备,网络侧设备才能准确接收到上行信息。
图5B所描述的是定时提前量不需要调整的示意图、图5C所描述的是定时提前量需要往前调整的示意图、图5D所描述的是定时提前量需要往后调整的示意图,其中,图5C所描述的场景为定时提前信息所指示的值为正值,图5D所描述的场景为定时提前信息所指示的值为负值。
本发明实施例中,用户设备确定调度信息和定时提前信息时,可选的,可以采用如下方式:
用户设备在第一TTI,确定调度信息和定时提前信息。
其中,用户设备在确定调度信息和定时提前信息时,可以是通过一个消息来确定的,也可以是通过两个消息来确定的,也就是说,调度信息和定时 提前信息可以携带在同一个消息中,也可以分别携带在不同的消息中,在此不做具体限定。
本发明实施例中,用户设备根据调度信息,采用调整后的定时提前量发送上行信息时,可选的,可以采用如下方式:
用户设备根据调度信息,在第二TTI采用调整后的定时提前量发送上行信息;
第二TTI与第一TTI之间间隔N个TTI,N大于或者等于0。
由于用户设备根据该调度命令发送上行信息的时候,在第二TTI就可以采用调整后的定时提前量来发送,用户设备和网络侧设备实现了同步,进而可以使网络侧能准确接收到用户设备发送的调度信息。
由于定时提前信息是对定时提前量调整,因此,进一步的,用户设备根据定时提前信息调整定时提前量之前,还包括:
用户设备确定定时提前量。
这样,确定的定时提前信息才是有意义的,如果定时提前量没有确定的话,确定定时提前信息也是没有意义的。
本发明实施例中,用户设备确定定时提前信息时,可选的,可以采用如下方式:
用户设备接收MAC CE,从MAC CE中获取定时提前信息;或者
用户设备接收物理层控制信令,从物理层控制信令中获取定时提前信息。
由于MAC CE里面包含6bit的调整值,因此,为了避免资源浪费,可以优先选择MAC CE携带定时提前信息。
当定时提前信息携带在MAC CE中时,用户设备会在接收到MAC CE的TTI之后的第6个TTI开始应用定时提前信息,或者说,开始应用根据定时提前信息调整后的定时提前量,具体的,比如,接收到MAC CE的TTI的编号为N,则可以在TTI的编号为N+6开始应用该定时提前信息,或者说,开始应用根据定时提前信息调整后的定时提前量,因此,可选的,N为6。
或者,当定时提前信息携带在物理层控制信令中时,通常,用户设备会 在确定定时提前信息的TTI之后的第4个TTI开始应用该定时提前信息,或者说,开始应用根据定时提前信息调整后的定时提前量,具体的,比如,确定定时提前信息的TTI的编号是N,则可以在TTI的编号为N+4开始应用该定时提前信息,或者说,开始应用根据定时提前信息调整后的定时提前量,因此,可选的,N为6。
当然,也可以在其它TTI开始应用定时提前信息,或者说,开始应用根据定时提前信息调整后的定时提前量,本发明不作限制。
本发明实施例中,可选的,用户设备确定调度信息时,可以采用如下方式:
用户设备接收物理层控制信令,从物理层控制信令中获取调度信息。
本发明实施例中,可选的,调度信息通常由用户标识C-RNTI(Cell-Radio Network Temporary Identity,小区无线网络临时标识)来加掩,携带的内容包括分配给用户设备的物理资源、调制编码方式、新数据指示等信息。
可选的,调度信息可以是上行授权,用于指示用户设备进行上行数据发送,也可以是下行指派,用于指示用户设备进行下行数据接收。
本发明实施例中,可选的,上行信息包括上行数据和/或上行HARQ反馈信息。
本发明实施例中,可选的,上行信息包括上行HARQ反馈信息;
在现有技术中,通常用户设备会在当前TTI接收到下行数据后,在之后的第四个TTI对接收到的下行数据进行上行HARQ反馈,进行上行HARQ反馈所使用的反馈资源通常是根据调度命令所占资源的位置获得的,但是,当用户设备在当前TTI之后的第六个TTI发送上行HARQ反馈信息时,可能与其它用户设备在N+2确定的N+6时刻所使用的反馈资源冲突,因此,为了避免反馈资源发生冲突,因此,用户设备发送上行信息之前,还包括如下操作:
用户设备确定发送上行HARQ反馈信息时能够采用的反馈资源;
此时,用户设备根据调度信息,采用调整后的定时提前量发送上行信息时,可选的,可以采用如下方式:
用户设备根据调度信息,采用调整后的定时提前量,在反馈资源上发送上行信息。
这样,用户设备可以预先确定反馈资源,进而可以避免不同用户设备占用相同的反馈资源,避免了资源冲突。
本发明实施例中,可选的,用户设备确定发送上行HARQ反馈信息时能够采用的反馈资源时,可以采用如下方式:
用户设备确定资源配置信息,将资源配置信息所对应的资源作为反馈资源。
本发明实施例中,可选的,资源配置信息包括时域信息、频域信息、码域信息中的至少一种。
为了使得用户设备能够灵活选择是通过本方案来获得上行同步,还是通过随机接入过程来获得上行同步,进一步的,用户设备根据调度信息,采用调整后的定时提前量发送上行信息之前,还包括如下操作:
用户设备接收定时提前量调整指示,定时提前量调整指示用于指示用户设备,能够根据定时提前信息调整定时提前量。
也就是说,用户设备接收到定时提前量调整指示之后,才开启根据本方案实现上行同步的功能,如果没有接收到定时提前量调整指示的话,只能通过随机接入过程来实现上行同步,只能根据随机接入过程获得的调整值对定时提前量进行调整。
由于本方案的前提是针对用户设备处于失步状态的场景来描述的,也就是说,本方案在这种场景下才有意义,如果用户设备处于同步状态下,网络侧设备能准确接收到用户设备的上行信息,不存在定时提前量,更不存在定时提前信息,因此,进一步的,用户设备确定定时提前量之前,还包括如下操作:
用户设备确定用户设备处于失步状态。
其中,用户设备确定定时提前信息时,可以开启对齐定时器,此时,用户设备确定处于失步状态时,可以通过如下方式来确定:
用户设备确定对齐定时器未超时时,确定用户设备处于失步状态。
在该方案中,用户设备不需要通过随机接入过程来获得上行同步,即用户设备不需要通过发送随机接入码就可以确定定时提前信息,减少了用户设备和网络侧设备进行随机接入码的交互,因此,解决了现有技术中存在的发送上行数据,或者发送下行数据的上行HARQ反馈的时延较长、效率较低的缺陷。
基于上述方案,参阅图6所示,本发明实施例中,上行数据发送的另一种流程如下:
步骤600:网络侧设备发送调度信息和定时提前信息,调度信息用于指示用户设备发送上行信息,定时提前信息用于调整用户设备发送上行信息时采用的定时提前量;
步骤610:网络侧设备接收上行信息,上行数据是根据调度信息和定时提前信息发送的。
本发明实施例中,定时提前量用于调整上行信息到达网络侧设备的时间,调整的目的是用于满足网络侧的接收定时要求。
本发明实施例中,定时提前信息所指示的值可以为正值,此时,需要将定时提前量往前调整,定时提前信息所指示的值也可以为负值,此时,需要将定时提前量往后调整,但是,无论定时提前信息所指示的值是正值还是负值,调整后的定时提前量还是正值,也就是说,无论定时提前量根据定时提前信息怎样调整,都要保证用户设备发送的上行信息准确达到网络侧设备,网络侧设备才能准确接收到上行信息。
图5B所描述的是定时提前量不需要调整的示意图、图5C所描述的是定时提前量需要往前调整的示意图、图5D所描述的是定时提前量需要往后调整的示意图,其中,图5C所描述的场景为定时提前信息所指示的值为正值,图5D所描述的场景为定时提前信息所指示的值为负值。
本发明实施例中,网络侧设备发送调度信息和定时提前信息时,可选的,可以采用如下方式:
网络侧设备在第一传输时间间隔TTI,发送调度信息和定时提前信息。
其中,网络侧设备在发送调度信息和定时提前信息时,可以是通过一个消息来发送的,也可以是通过两个消息来发送的,也就是说,调度信息和定时提前信息可以携带在同一个消息中,也可以分别携带在不同的消息中,在此不做具体限定。
本发明实施例中,网络侧设备接收上行信息时,可选的,可以采用如下方式:
网络侧设备在第二TTI接收上行信息;
第二TTI与第一TTI之间间隔N个TTI,N大于或者等于0。由于定时提前信息是对定时提前量调整,因此,进一步的,网络侧设备接收上行信息之前,还包括如下操作:
网络侧设备发送定时提前量。
这样,用户设备确定的定时提前信息才是有意义的,如果定时提前量没有确定的话,确定定时提前信息也是没有意义的。
本发明实施例中,网络侧设备发送定时提前信息时,可选的,可以采用如下方式:
网络侧设备发送MAC CE,MAC CE中携带定时提前信息;或者
网络侧设备发送物理层控制信令,物理层控制信令中携带定时提前信息。
由于MAC CE里面包含6bit的调整值,因此,为了避免资源浪费,可以优先选择MAC CE携带定时提前信息。
本发明实施例中,网络侧设备发送调度信息时,可选的,可以采用如下方式:
网络侧设备发送物理层控制信令,物理层控制信令中携带调度信息。
当定时提前信息携带在MAC CE中时,用户设备会在接收到MAC CE的TTI之后的第6个TTI开始应用定时提前信息,或者说,开始应用根据定时提前信息调整后的定时提前量,具体的,比如,接收到MAC CE的TTI的编号为N,则可以在TTI的编号为N+6开始应用该定时提前信息,或者说,开始应用根据 定时提前信息调整后的定时提前量,因此,可选的,N为6。
或者,当定时提前信息携带在物理层控制信令中时,通常,用户设备会在确定定时提前信息的TTI之后的第4个TTI开始应用该定时提前信息,或者说,开始应用根据定时提前信息调整后的定时提前量,具体的,比如,确定定时提前信息的TTI的编号是N,则可以在TTI的编号为N+4开始应用该定时提前信息,或者说,开始应用根据定时提前信息调整后的定时提前量,因此,可选的,N为6。
当然,也可以在其它TTI开始应用定时提前信息,或者说,开始应用根据定时提前信息调整后的定时提前量,本发明不作限制。
本发明实施例中,可选的,上行信息包括上行数据和/或上行HARQ反馈信息。
本发明实施例中,可选的,上行信息包括上行HARQ反馈信息;
在现有技术中,通常用户设备会在当前TTI接收到下行数据后,在之后的第四个TTI对接收到的下行数据进行上行HARQ反馈,进行上行HARQ反馈所使用的反馈资源通常是根据调度命令所占资源的位置获得的,但是,当用户设备在当前TTI之后的第六个TTI发送上行HARQ反馈信息时,可能与其它用户设备在N+2确定的N+6时刻所使用的反馈资源冲突,因此,为了避免反馈资源发生冲突,因此,网络侧设备接收上行信息之前,还包括如下操作:
网络侧设备发送资源配置信息,资源配置信息所对应的资源为反馈资源,反馈资源是发送上行HARQ反馈信息时能够采用的资源。
这样,用户设备可以预先确定反馈资源,进而可以避免不同用户设备占用相同的反馈资源,避免了资源冲突。
可选的,资源配置信息包括时域信息、频域信息、码域信息中的至少一种。
为了使得用户设备能够灵活选择是通过本方案来获得上行同步,还是通过随机接入过程来获得上行同步,进一步的,接网络侧设备接收上行信息之 前,还包括如下操作:
网络侧设备发送上行定时提前量调整指示,定时提前量调整指示用于指示用户设备,能够根据定时提前信息调整定时提前量。
也就是说,用户设备接收到定时提前量调整指示之后,才开启根据本方案实现上行同步的功能,如果没有接收到定时提前量调整指示的话,只能通过随机接入过程来实现上行同步,只能根据随机接入过程获得的调整值对定时提前量进行调整。
在该方案中,用户设备不需要通过随机接入过程来获得上行同步,即用户设备不需要通过发送随机接入码就可以确定定时提前信息,也就是说,网络侧设备不需要在接收到随机接入码的时候才向用户设备发送定时提前信息,而是可以实时或者按照一定的周期发送,网络侧设备和用户设备减少了交互随机接入码的过程,因此,解决了现有技术中存在的发送上行数据,或者发送下行数据的上行HARQ反馈的时延较长、效率较低的缺陷。
基于上述方案,参阅图7A所示,本发明实施例中,随机接入的一种流程如下:
步骤700:用户设备接收调度信息,调度信息中携带上行资源信息,上行资源信息用以指示发送上行信息时所能够采用的资源,调度信息用于指示用户设备发送上行信息;
步骤710:用户设备确定处于失步状态时,采用上行资源发送随机接入码;
步骤720:用户设备接收随机接入响应,随机接入响应是根据随机接入码发送的。
本发明实施例中,用户设备采用上行资源发送随机接入码时,可选的,可以采用如下方式:
用户设备采用至少一个目标物理资源块发送随机接入码;
其中,为了明确发送随机接入码时使用的目标物理资源块,减少网络侧设备检测随机接入码的复杂度,可选的,目标物理资源块可以为如下形式:
目标物理资源块为资源中频域位置小于第一频域位置预设门限值,或者 编号小于第一编号预设门限值的物理资源块;或者
目标物理资源块为资源中频域位置大于第二频域位置预设门限值,或者编号大于第二编号预设门限值的物理资源块;或者
目标物理资源块为预设的。
其中,目标物理资源块为资源中频域位置小于第一频域位置预设门限值,或者编号小于第一编号预设门限值的物理资源块时,可选的,目标物理资源块也可以为资源中最低频域位置的物理资源块,或者最小编号的物理资源块。
同理,目标物理资源块为资源中频域位置大于第二频域位置预设门限值,或者编号大于第二编号预设门限值的物理资源块时,可选的,目标物理资源块也可以为资源中最高频域位置的物理资源块,或者最大编号的物理资源块。
本发明实施例中,用户设备采用上行资源发送随机接入码之前,还包括如下操作:
用户设备确定随机接入资源信息,随机接入资源信息包括至少一个随机接入码。
可选的,至少一个随机接入码属于同一组;
为了降低用户设备发送随机接入码时的冲突,此时,用户设备采用上行资源发送随机接入码时,可选的,可以采用如下方式:
用户设备从至少一个随机接入码中选择一个随机接入码,并采用上行资源发送选择出的一个随机接入码。
可选的,至少一个随机接入码包括至少一个专用随机接入码;
为了降低用户设备发送随机接入码时的冲突,此时,用户设备采用上行资源发送随机接入码时,可以采用如下方式:
用户设备从至少一个专用随机接入码中选择一个专用随机接入码,并采用上行资源发送选择出的一个专用随机接入码。
为了能够复用现有随机接入信道资源,不需要在上行资源上引入随机接入信道资源,减少复杂度,进一步的,随机接入资源信息还包括随机接入信道资源信息;
如图7B所示,方法还包括:用户设备确定处于失步状态时,采用随机接入信道资源发送随机接入码,随机接入信道资源为随机接入信道资源信息所指示的信道资源。
可选的,用户设备采用随机接入信道资源发送随机接入码时,采用如下方式:
用户设备采用上行资源所在TTI的随机接入信道资源,发送随机接入码;和/或
用户设备采用上行资源发送随机接入码;和/或
用户设备采用上行资源所在TTI之后的随机接入信道资源,发送随机接入码。
可选的,随机接入信道资源信息为随机接入信道的时频信息和/或频域位置信息,或者,为用于指示随机接入信道的时频信息和/或频域位置信息的信息。
由于发起随机接入过程的目的是获得上行同步,而上行同步的目的是网络侧设备能准确接收用户设备发送的上行信息,因此,进一步的,用户设备接收随机接入响应之后,还包括如下操作:
用户设备根据随机接入响应发送上行信息。
用户设备在接收到调度信息后,如果用户设备处于失步状态时,是不能发送上行信息的,但是,调度信息中携带上行资源信息,因此,存在上行资源信息所指示的资源浪费的情况,在该方案中,可以采用该上行资源信息所指示的资源来发送随机接入码,发起随机接入过程,实现上行同步,这样,可以避免资源浪费,提高资源的利用率。
同时,由于现有技术中时上行数据到达用户设备时,用户设备才发起随机接入过程,而本方案中,在接收到调度命令时,就发起随机接入过程,当上行数据或者下行数据到达用户设备时,用户设备就可以发送数据,或者进行上行HARQ反馈,因此,本方案还可以解决现有技术中存在的发送上行数据,或者发送下行数据的上行HARQ反馈的时延较长、效率较低的缺陷。
基于上述方案,参阅图8所示,本发明实施例中,随机接入的另一种流程如下:
步骤800:网络侧设备发送调度信息,调度信息中携带上行资源信息,上行资源信息用以指示发送上行信息时所能够采用的资源,调度信息用于指示用户设备发送上行信息;
步骤810:网络侧设备接收随机接入码,随机接入码根据上行资源发送的;
步骤820:网络侧设备根据随机接入码发送随机接入响应。
本发明实施例中,可选的,网络侧设备接收随机接入码之前,还包括如下操作:
网络侧设备发送随机接入资源信息,随机接入资源信息包括至少一个随机接入码。
本发明实施例中,可选的,至少一个随机接入码属于同一组;
为了降低随机接入冲突,本发明实施例中,可选的,网络侧设备接收随机接入码时,可以采用如下方式:
网络侧设备接收至少一个随机接入码中的一个随机接入码。
本发明实施例中,可选的,至少一个随机接入码包括至少一个专用随机接入码;
为了降低随机接入冲突,此时,网络侧设备接收随机接入码时,可选的,可以采用如下方式:
网络侧设备接收至少一个专用随机接入码中的一个专用随机接入码。
为了能够复用现有随机接入信道资源,不需要在上行资源上引入随机接入信道资源,减少复杂度,可选的,随机接入资源信息包括随机接入信道资源信息。
本发明实施例中,可选的,随机接入信道资源信息为随机接入信道的时频信息和/或频域位置信息,或者,为用于指示随机接入信道的时频信息和/或频域位置信息的信息。
由于发起随机接入过程的目的是获得上行同步,而上行同步的目的是网 络侧设备能准确接收用户设备发送的上行信息,因此,进一步的,网络侧设备根据随机接入码发送随机接入响应之后,还包括如下操作:
网络侧设备接收上行信息。
用户设备在接收到网络侧设备发送的调度信息后,如果用户设备处于失步状态时,是不能发送上行信息的,但是,调度信息中携带上行资源信息,因此,存在上行资源信息所指示的资源浪费的情况,在该方案中,网络侧设备接收到的随机接入码可以采用该上行资源信息所指示的资源来发送,发起随机接入过程,实现上行同步,这样,可以避免资源浪费,提高资源的利用率。
同时,由于现有技术中时上行数据到达用户设备时,用户设备才发起随机接入过程,而本方案中,在接收到调度命令时,就发起随机接入过程,当上行数据或者下行数据到达用户设备时,用户设备就可以发送数据,或者进行上行HARQ反馈,因此,本方案还可以解决现有技术中存在的发送上行数据,或者发送下行数据的上行HARQ反馈的时延较长、效率较低的缺陷。
另外,在通信系统中,更大的传输带宽是提升系统中数据的传输速率的重要因素,因此,为了增加传输带宽,提出了CA(Carrier Aggregation,,载波聚合)技术,载波聚合是将至少两个载波聚合在一起以支持更大的传输带宽。在LTE R13 CA增强项目中同意引入PUCCH(Physical Uplink Control Channel,物理上行控制信道)在Scell(Secondary Cell,辅小区)上发的概念。
在这个Scell上承载的PUCCH可以承载ACK(Acknowledgement,确认),CSI(Channel State Indicator,信道状态指示),以及SR(scheduling request,调度请求)的发送。即使PUCCH在Scell上发,这个Scell也可以被去激活。
这样就存在一种情况:当用户设备在Scell上和Pcell(Primary Cell,主小区)上都被配置了SR时,如果触发了SR,但此时Scell被去激活,用户设备不能在Scell上发送SR。同时,如果Pcell配置的SR的周期很长,就会导致用户设备不得不等到Pcell上的SR资源到来才能在Pcell上发送SR,以请求上行资源,因此上行发送数据延迟较大。
参阅图9所示,为了减少用户设备发送上行数据时延,提出了如下一种上行数据的发送方法,具体过程如下:
该过程的应用场景如下:用户设备确定配置信令,该配置信令中包括为Pcell配置的SR资源,并应用网络的配置信令配置的SR资源。
步骤900:用户设备确定有上行数据或BSR(Buffer Status Report,缓存状态报告)需要发送或或触发SR;
步骤910:用户设备确定符合预设条件时,在Pcell上触发随机接入过程。
通过上述方案,可以避免由于Scell上SR资源不可用,而用户设备能够采用的PCell上的有效SR资源比较晚时,上行数据或BSR可能会被延迟。
用户设备确定符合预设条件,可选的,可以采用如下方式:
用户设备判断有上行数据或者BSR需要发送的时刻,或者触发SR时刻,与用户设备能够采用的Pcell上的有效的SR资源的时刻的时间间隔大于时间阈值。
可选的,时间阈值可以为20ms,30ms等。
需要说明的时,如果时间间隔小于或者等于时间阈值时,就不发起随机接入过程,而是通过配置的SR资源来请求发送上行数据的上行资源。
也就是说,通过对时间间隔的判断,可以选择通过随机接入过程,或者通过SR资源来请求上行资源,以减少上行数据或BSR时延。
用户设备确定符合预设条件,可选的,可以采用如下方式:
用户设备判断SR资源的周期大于时间阈值。
可选的,时间阈值可以为20ms,40ms等。
用户设备确定符合预设条件,可选的,可以采用如下方式:
用户设备判断有上行数据或者BSR需要发送,或者触发SR。
需要说明的是,上述过程是说配置了SR资源,但是是通过随机接入过程来请求上行资源,是基于用户设备判断有上行数据的时刻,或者BSR需要发送的时刻,或者触发SR,Scell没有有效的SR资源。
其中,没有有效的SR资源是指如下至少一种情况:
SR资源没有配置在Scell上,或者,在Scell上配置了SR资源但是Scell被去激活,或者,在Scell上配置了SR资源但是Scell上行失步。
用户设备通过在Pcell上触发随机接入过程,可以避免由于Scell上的SR资源不可用,而PCell上配置的有效SR资源比较晚时,上行数据或BSR可能会被延迟。进一步的,为了避免资源浪费,用户设备确定符合预设条件之后,还要进一步判断上行数据的数据量是否达到数据量阈值,在达到数据量阈值时,才在Pcell上发起随机接入过程。
可选的,数据量阈值为1000Bytes、3000Bytes等。
通过对上行数据的数据量的判断,可以减少上行数据或BSR的开销。
可选的,用户设备在执行步骤910之前,还包括如下操作:
随机接入过程配置指示,该指示用于开启用户设备确定符合预设条件时,在Pcell上触发随机接入过程的功能。
也就是说,在接收到随机接入过程配置指示之后,如果用户设备确定符合预设条件时,才在Pcell上触发随机接入过程;如果没有接收到随机接入过程配置指示,即使用户设备确定符合预设条件时,也不会在Pcell上触发随机接入过程。
