未来的5G系统,更是会相应地存在以下典型的业务场景:高吞吐量、高容量、高频谱效率的多媒体移动宽带(Mobile Broadband,MBB)业务,例如长期演进语音(Voice over Long Term Evolution,VoLTE)业务;低功耗的海量物联网(Massive MTC)业务;低时延高可靠的物联网(Low-Latency&Ultra-Reliable MTC)业务,例如,V2X业务。在这些场景中,周期性的业务传输将成为一种典型的业务传输方式。
另一方面,随着通信技术的发展,LTE系统已经能够提供多种调度方式,例如,动态调度,静态调度和半静态调度(Semi-Persistent Scheduling,SPS)等。
其中,半静态调度也可以称为半持续调度,即,按照一定的周期,为用户分配资源,从而,在该周期内的资源分配均无需调度信令指示。与动态调度相比,这种调度方式灵活性稍差,但控制信令开销较小,适合突发特征不明显、有保障速率要求的业务,例如,上文中提到的VoLTE业务、V2X业务等。根据需求,不同的业务或不同的业务类型通常需要配置的不同的SPS资源。
现有的技术中,用户在一段时间内通常只传输一种业务类型的业务,针对用户传输的业务类型,网络侧设备通过物理下行控制信道(Physical Downlink Control Channel,PDCCH)为其分配一个SPS资源。当业务传输完毕时,网络侧设备再通过PDCCH释放SPS资源。当用户传输新的业务类
型的业务时,网络侧设备再次发送PDCCH分配新的SPS资源。此外,当某一业务根据需求,其接收周期或发送周期发生变化,或者业务传输中数据包的大小发生变化时,也需要按照上述流程经历SPS资源的释放和重分配的过程。上述过程会造成大量PDCCH资源的占用。
此外,在现有技术的一些特别的情况下,用户除了传输当前的业务外,还可能临时传输其他业务类型的业务。在这种情况下,网络侧设备通常通过PDCCH采用动态调度的方式临时指示当前子帧的SPS资源的配置。由于新的业务仍然为周期性恒定的,下一子帧的SPS资源的配置按照需求,也仍然需要通过PDCCH采用动态调度的方式指示。该方式可以即时解决的SPS资源的配置问题,但是在每个子帧上都进行SPS资源的配置,也会造成大量PDCCH资源的占用。

优选地,本发明各实施例中的网络设备为基站,本发明各实施例中的移动台为用户设备。
此外,本发明的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如,计算机可读介质可以包括,但不限于:磁存储器件(例如,硬盘、软盘或磁带等),光盘(例如,CD(Compact Disk,压缩盘)、DVD(Digital Versatile Disk,数字通用盘)等),智能卡和闪存器件(例如,EPROM(Erasable Programmable Read-Only Memory,可擦写可编程只读存储器)、卡、棒或钥匙驱动器等)。另外,本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于,无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
图1是本发明一个实施例的业务传输的通信系统的示意图。如图1所示,该通信系统100包括网络设备102,网络设备102可包括多个天线例如,天线104、106、108、110、112和114。另外,网络设备102可附加地包括发射机链和接收机链,本领域普通技术人员可以理解,它们均可包括与信号发送和接收相关的多个部件(例如处理器、调制器、复用器、解调器、解复用器或天线等)。
网络设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而,可以理解,网络设备102可以与类似于终端设备116或122的任意数目的终端设备通信。终端设备116和122可以是例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、PDA和/或用于在无线通信系统100上通信的任意其它适合设备。
如图1所示,终端设备116与天线112和114通信,其中天线112和114
通过前向链路118向终端设备116发送信息,并通过反向链路120从终端设备116接收信息。此外,终端设备122与天线104和106通信,其中天线104和106通过前向链路124向终端设备122发送信息,并通过反向链路126从终端设备122接收信息。
例如,在频分双工(FDD,Frequency Division Duplex)系统中,例如,前向链路118可利用与反向链路120所使用的不同频带,前向链路124可利用与反向链路126所使用的不同频带。
再例如,在时分双工(TDD,Time Division Duplex)系统和全双工(Full Duplex)系统中,前向链路118和反向链路120可使用共同频带,前向链路124和反向链路126可使用共同频带。
被设计用于通信的每个天线(或者由多个天线组成的天线组)和/或区域称为网络设备102的扇区。例如,可将天线组设计为与网络设备102覆盖区域的扇区中的终端设备通信。在网络设备102通过前向链路118和124分别与终端设备116和122进行通信的过程中,网络设备102的发射天线可利用波束成形来改善前向链路118和124的信噪比。此外,与网络设备通过单个天线向它所有的终端设备发送信号的方式相比,在网络设备102利用波束成形向相关覆盖区域中随机分散的终端设备116和122发送信号时,相邻小区中的移动设备会受到较少的干扰。
在给定时间,网络设备102、终端设备116或终端设备122可以是无线通信发送装置和/或无线通信接收装置。当发送数据时,无线通信发送装置可对数据进行编码以用于传输。具体地,无线通信发送装置可获取(例如生成、从其它通信装置接收、或在存储器中保存等)要通过信道发送至无线通信接收装置的一定数目的数据比特。这种数据比特可包含在数据的传输块(或多个传输块)中,传输块可被分段以产生多个码块。
此外,该通信系统100可以是公共陆地移动网络(英文全称可以为:Public Land Mobile Network,英文简称可以为:PLMN)网络或者D2D网络或者M2M网络或者V2V网络或者V2X网络或者其他网络,图1只是举例的简化示意图,网络中还可以包括其他网络设备,图1中未予以画出。
本发明实施例的方案可以应用于现有的蜂窝通信系统,如全球移动通讯(Global System for Mobile Communication,GSM),宽带码分多址(Wideband Code Division Multiple Access,WCDMA),长期演进(Long Term Evolution,
LTE)等系统中,所支持的通信主要是针对语音和数据通信的。通常来说,一个传统基站支持的连接数有限,也易于实现。
下一代移动通信系统将不仅支持传统的通信,还将支持机器对机器(Machine to Machine,M2M)通信,或者MTC通信。根据预测,到2020年,连接在网络上的MTC设备将会达到500到1000亿,这将远超现在的连接数。对M2M类业务,由于其业务种类千差万别,对网络需求存在很大差异。
在LTE系统中,SPS机制重点针对周期性的业务传输,例如最典型的VoLTE业务,制定了半静态调度(SPS)的调度方式,其主要机制是网络侧设备,例如基站,首先通过无线资源控制(Radio Resource Control,RRC)信令,对移动台进行SPS资源的相应配置,例如,配置多组用于SPS的资源分配参数。资源分配参数可以包括传输周期、传输块大小、传输块的位置和个数、发射功率控制参数、混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)进程数等。随后,在需要时通过PDCCH,为移动台实际分配所使用的一组资源分配参数,资源分配参数一旦激活,则周期性有效。在LTE系统中,由于VoLTE业务的数据包大小均为几十个字节,且周期固定,因此采用SPS机制会在一定程度上节省控制信令。
具体如图2所示的SPS工作流程的示意图。在图2中,为移动台分配的资源分配参数中,传输周期为20ms,图中示出了3个传输块(这里传输块的个数仅为示意性的)。当为移动台分配的资源激活后,由于后续不再发送PDCCH,因此传输周期、传输块大小等均无法改变,只能通过释放后再激活的方式重新配置资源。
而在未来的LTE演进以及5G系统中,随着周期性业务的逐渐增多,采用SPS机制的场景也会越来越多,具体可以有但不限于以下几个场景。
场景1:在MBB业务中,多种周期性业务混和在一起进行传输,例如,VoLTE业务、即时通信心跳数据等等可以混和在一起进行传输。在这些场景中,网络可能触发一种或多种SPS配置或资源分配方式,即分配一组资源分配参数,在需要的时候再对资源分配参数进行更新。
场景2:在低功耗的Massive MTC业务中,网络需要周期性的进行一些数据发送,而移动台同样也需要周期性的进行数据发送,且数据包大小可能发生改变。
场景3:在低时延高可靠的物联网业务中,尤其是V2X业务场景下,无论是车辆还是网络都需要周期性的广播网络中的车辆状态,且数据包大小是可变的。
上述三种场景有可能对应图3所示的业务需求变化。例如,一个业务原来对SPS配置的需求如传输块1至3所示,并且传输周期为T1;业务需求变化后,需求如传输块4至6所示,并且传输周期为T2。应理解,这里传输块的大小和个数仅是示意性的,而非对本发明实施例的限制。
首先,对本发明实施例中半静态调度时使用的资源分配参数集合和资源分配参数进行详细说明。
在本发明实施例中,资源分配参数用于周期性资源调度(或者说,周期性资源分配),或者说,该资源分配参数可以是与周期性资源调度相关的参数。作为示例而非限定,每个资源分配参数集合中的资源分配参数包括以下至少一种:
传输周期、传输块大小、传输块的个数、传输块的位置、上行功率控制参数、调制编码方案(Modulation and Coding Scheme,MCS)和混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)进程数。
具体地说,传输周期可以是指移动台(或网络设备)针对同一业务,连续传输(发送或接收)两次数据或信息等所间隔的时间。作为示例而非限定,该传输周期可以为20ms、10ms或5ms。
需要说明的是,在本发明实施例中,移动台(或网络设备)传输(发送或接收)数据或信息的对象可以是网络设备,也可以是其他移动台等,本发明并未特别限定。当移动台向网络设备发送数据或信息时,该传输周期可以是上行传输周期。当移动台接收网络设备发送的数据或信息时,该传输周期可以是下行传输周期。
在本发明实施例中,传输块大小是指移动台(或网络设备)传输一次数据占用的时频资源块的大小。例如,时域上的M个符号长度,频域上的N个资源块(Resource Block,RB)构成了传输块。
应理解,本发明实施例中的传输块大小可以和业务每次要传输的数据包的大小相对应。优选地,传输块可以承载一次传输的数据包。
在本发明实施例中,传输块的个数是指使用相同的SPS配置进行业务传输时,可以连续传输的次数。传输块的个数也可以以传输业务所使用的连续
的传输时间间隔(Transmission Time Interval,TTI)的数量来表示,本发明实施例对此不作限定。
在本发明实施例中,传输块的位置是指传输块在时域和频域上的位置,例如传输块从哪个符号开始,从哪个RB开始等等。
在本发明实施例中,资源分配参数集合中还可以包括传输业务时,调制信号所使用的调制编码方案MCS。
上行功率控制参数是移动台在一次或多次发送数据或信息等所使用的发射功率的相关参数,作为示例而非限定,在本发明实施例中,该上行功率控制参数可以是移动台能够使用的发射功率的最大值。
目前,普遍使用停等式HARQ协议,因此需要配置相应的HARQ的进程数。在等待某个HARQ进程的反馈信息过程中,可以继续使用其他的空闲进程传输数据包。HARQ的最小RTT(Round Trip Time)定义为一次数据包传输过程的完成时间,包括从一个数据包在发送端开始发送,接收端接收处理后,根据结果反馈ACK/NACK信令,发送端解调处理ACK/NACK信号后,确定下一帧进行重传或传送新数据包的全过程。HARQ的进程数与HARQ的最小RTT时间是紧密相关的。对于频分双工(Frequency Division Duplexing,FDD)来说,其HARQ的进程数等于HARQ的最小RTT时间中包含的子帧数目;对于时分双工(Time Division Duplexing,TDD)来说,其HARQ的进程数为HARQ的最小RTT时间中包含的同一发送方向的子帧数目。
应理解,以上列举的资源分配参数所包括的具体参数仅为示例性说明,本发明并未限定于此,其他与周期性资源调度或周期性资源分配相关的参数均落入本发明的保护范围内。
需要说明的是,在本发明实施例中,一个资源分配参数集合所包括的资源分配参数的种类并未特别限定,例如,一个资源分配参数集合可以包括以上列举的全部资源分配参数,或者一个资源分配参数集合可以包括以上列举的部分资源分配参数,并且,后述“N个资源分配参数集合”中的每个资源分配参数集合所包括的资源分配参数的种类和数量可以相同也可以相异,本发明并未特别限定。
图4示出了本发明一个实施例的用于传输业务的方法400的示意性流程图。方法400执行于网络设备和移动台之间,可以包括以下步骤。
S401,网络设备向移动台发送第二控制信令,第二控制信令用于指示N个资源分配参数集合,该N个资源分配参数集合包括第一资源分配参数集合和第二资源分配参数集合。相应地,移动台接收网络设备发送的第二控制信令。
其中,第一资源分配参数集合和第二资源分配参数集合均是网络设备为移动台分配的用于进行SPS的资源分配参数集合,第一资源分配参数集合和第二资源分配参数集合均包括至少一个资源分配参数。
第二控制信令可以是高层控制信令。优选地,第二控制信令为无线资源控制(Radio Resource Control,RRC)信令。
在一个优选的实施例中,网络设备和移动台中存储有相互协商好的多套SPS配置(多个资源分配参数集合)和多个索引标识之间的一一对应关系,其中,多个资源分配参数集合和多个索引标识之间的一一对应关系中包括N个资源分配参数集合和N个索引标识之间的一一对应关系。即,网络设备和移动台存储有N个资源分配参数集合和N个索引标识之间的一一对应关系。第二控制信令包括N个索引标识时,就可以指示N个资源分配参数集合。后续,第三控制信令和第一控制信令分别指示第一资源分配参数集合和第二资源分配参数集合时,也可以通过索引标识指示。
应理解,在本发明实施例中,第二控制信令指示的资源分配参数集合中可以只包括上文中列举的资源分配参数的部分参数。剩余的部分参数的具体内容则通过S405中的第一控制信令下发。
应理解,S401不是必需的,网络设备和移动台中可以不存储多个资源分配参数集合和多个索引标识之间的一一对应关系,后续网络设备直接向移动台发送资源分配参数集合的具体内容,或者直接向移动台发送各个资源分配参数的具体内容(而不通过索引指示),本发明实施例对此不作限定。
S402,网络设备向移动台发送第三控制信令,该第三控制信令用于指示该移动台以半静态调度SPS的方式,使用第一资源分配参数集合传输业务。相应地,移动台接收网络设备发送的第三控制信令。
具体而言,第三控制信令用于指示移动台以SPS的方式,使用第一资源分配参数集合传输当前的业务,即传输第一业务。
应理解,S402也不是必需的,即本发明实施例对移动台如何进入SPS方式传输数据不作限定。
S403,移动台以半静态调度SPS的方式,使用第一资源分配参数集合传输当前的业务。即,移动台使用第一资源分配参数集合传输当前的第一业务。
S404,当移动台当前传输的业务的需求发生变化时,网络设备根据移动台的业务需求的变化,确定第二资源分配参数集合。
具体而言,网络设备根据移动台的业务需求的变化,确定第二资源分配参数集合包括以下几种情况。
第一种情况针对当前正在传输的业务的需求变化,具体而言可以为:网络设备根据当前正在传输的第一业务的需求的变化,确定用于传输需求变化后的第一业务的第二资源分配参数集合。相应地,在S405中网络设备向移动台发送的第一控制信令,用于指示移动台以SPS的方式,使用第二资源分配参数集合替代第一资源分配参数集合传输需求变化后的第一业务。
具体的例子可以如图5所示,需求变化前,第一业务通过传输块1、2和3进行传输。需求变化可以是数据包大小变大并且传输周期缩短。需求变化后,第一业务通过传输块4、5和6进行传输。
第二种情况针对新增业务,具体而言可以为:网络设备根据新增的第二业务的需求和当前正在传输的第一业务的需求,确定用于传输第一业务和第二业务的第二资源分配参数集合。相应地,第一控制信令用于指示移动台以SPS的方式,使用第二资源分配参数集合替代第一资源分配参数集合,传输第一业务和第二业务。
具体的例子可以如图6所示,需求变化前,第一业务通过传输块1、2和3进行传输。需求变化可以是新增的第二业务。需求变化后,网络设备根据需求,确定通过传输块4、5和6传输第一业务和第二业务。
第三种情况也针对新增业务,具体而言可以为:网络设备根据新增的第二业务的需求,确定用于传输第二业务的第二资源分配参数集合;网络设备确定仍使用第一资源分配参数集合传输第一业务。相应地,第一控制信令用于指示移动台以SPS的方式,使用第一资源分配参数集合传输第一业务,使用第二资源分配参数集合传输第二业务。
具体的例子可以如图7所示,需求变化前,第一业务通过传输块1、2和3进行传输。需求变化可以是新增的第二业务。需求变化后,网络设备根据需求,确定通过传输块4、5和6传输第一业务,通过传输块7、8和9传输第二业务。其中,传输块4、5和6与传输块1、2和3对应的资源分配参
数集合均为第一资源分配参数集合,即,仍使用第一资源分配参数集合传输第一业务;传输块7、8和9对应的资源分配参数集合为不同于传输块1至6的资源分配参数集合,即,使用第二资源分配参数集合传输第二业务。
S405,网络设备向移动台发送第一控制信令,第一控制信令用于指示移动台以SPS的方式,使用第二资源分配参数集合替代第一资源分配参数集合传输需求变化后的业务,或者使用第二资源分配参数集合和第一资源分配参数集合传输需求变化后的业务。相应地,移动台接收网络设备发送的第一控制信令。
应理解,在移动台接收第二控制信令,并已经获取第二控制信令指示的资源分配参数集合和索引标识的一一对应关系的情况下,第二控制信令指示的资源分配参数集合中可以只包括上文中列举的资源分配参数的部分参数(例如,传输块大小和传输块的位置等参数)。第一控制信令通过相应的索引标识指示该部分参数,剩余的部分参数的具体内容则通过第一控制信令直接下发。
具体地,例如,第一控制信令一部分可以包括指示第二资源分配参数集合(其中包括传输块大小和传输块的位置等参数)的索引标识,另一部分还可以包括上文中列举的资源分配参数的其他参数的具体内容。
本发明中,资源分配参数集合中参数的设置、索引标识的设置和各控制信令的设置可以非常灵活,而不限于本发明实施例中所例举的形式。

该过程中移动台可以释放第一资源分配参数集合。应理解,本实施例网络设备不需要向移动台发送一条PDCCH指示释放第一资源分配参数集合,再发送一条PDCCH指示配置第二资源分配参数集合,而是直接由第二资源分配参数集合替代第一资源分配参数集合,可以节省信令开销。
针对第二种情况,第二资源分配参数集合是网络设备根据新增的第二业
务的需求和当前正在传输的第一业务的需求确定的,第一控制信令用于指示移动台以SPS的方式,使用第二资源分配参数集合替代述一资源分配参数集合传输需求变化后的业务。

在第三种情况下,第一控制信令中可以包括第一信息域和第二信息域,第一信息域用于承载第一资源分配参数集合的信息,第二信息域用于承载第二资源分配参数集合的信息。具体地,例如,使用RNTI1携带第一业务的SPS配置(第一资源分配参数集合),使用SPS-RNTI2携带第二业务的SPS配置(第二资源分配参数集合)。再如,使用Index1指示第一业务的SPS配置(第一资源分配参数集合),使用Index2指示第二业务的SPS配置(第二资源分配参数集合),等等,本发明对具体的指示和承载方式不作限定。对于移动台而言,移动台在接收到第一控制信令后,在第一信息域和第二信息域分别指示的第一资源分配参数集合和第二资源分配参数集合对应的资源上均进行数据的传输(发送或接收)。
在本发明实施例中,第三控制信令可以通过索引标识(例如第一索引标识)指示第一资源分配参数集合。第一控制信令可以通过索引标识(例如第二索引标识)指示第二资源分配参数集合。
应理解,本发明的传输包括上行传输和下行传输,即包括移动台发送和移动台接收。
应理解,本发明实施例的方法也可以称作是一种对SPS的重配置的方法。
还应理解,本发明实施例的索引标识,例如N个索引标识中的任意一个索引标识、第一索引标识和第二索引标识可以为编号或无线网络临时标识(Radio Network Tempory Identity,RNTI)。即,将编号或RNTI用于携带表示资源分配参数集合(例如N个资源分配参数集合中的任意一个资源分配参数集合、第一资源分配参数集合和第二资源分配参数集合)的索引标识。
还应理解,本发明实施例中,优选地,第三控制信令和/或第一控制信令可以为物理下行控制信道PDCCH。此外,第三控制信令和/或第一控制信令还可以为其他物理控制信道,例如增强的物理下行控制信道(Enhanced PDCCH,E-PDCCH)等,本发明实施例对此不作限定。
