Description

用于传输下行数据的资源的确定和配置方法、终端和基站
本申请要求在2017年9月11日提交中国专利局、申请号为201710814233.9、发明名称为“用于传输下行数据的资源的确定和配置方法、终端和基站”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域,尤其涉及用于传输下行数据的资源的确定和配置方法、终端和基站。
背景技术
移动互联网正在颠覆传统移动通信业务模式,为用户提供前所未有的使用体验,深刻影响着人们工作生活的方方面面。移动互联网将推动人类社会信息交互方式的进一步升级,为用户提供增强现实、虚拟现实、超高清(3D)视频、移动云等更加丰富的业务体验。移动互联网的进一步发展将带来未来移动流量超千倍增长,推动移动通信技术和产业的新一轮变革。而物联网则扩展了移动通信的服务范围,从人与人通信延伸到人与物、物与物智能互联,使移动通信技术渗透至更加广阔的行业和领域。未来,移动医疗、车联网、智能家居、工业控制、环境监测等将会推动物联网应用爆发式增长,数以千亿的设备将接入网络,实现真正的“万物互联”。同时,海量的设备连接和多样化的物联网业务也会给移动通信带来新的技术挑战。
随着新的业务需求的持续出现和丰富,对未来移动通信系统提出了更高的性能需求,例如更高的峰值速率、更好的用户体验速率、更小的时延、更高的可靠性、更高的频谱效率和更高的能耗效率等,并需要支持更多的用户接入以及使用各种业务类型。为了支持数量巨大的各类终端连接以及不同的 业务类型,上下行资源的灵活配置成为技术发展的一大趋势。未来的系统资源可以根据业务的不同,划分成不同的子带,并在子带上划分长度不同的TTI(Transmission Time Interval,传输时间间隔),以满足多种业务需求。
现有LTE(Long Term Evolution,长期演进)FDD(Frequency Division Duplexing,频分双工)系统使用FS1(Frame Structure Type 1,帧结构类型1),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,每个子帧内由分为两个0.5ms长的时隙。上行和下行数据发送的TTI时长为1ms。
现有LTE TDD(Time Division Duplexing,时分双工)系统使用FS2(Frame Structure Type 2,帧结构类型2),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的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DwPTS(Downlink Pilot Time Slot,下行传输时隙)、GP(Guard Period,保护间隔)和UpPTS(Uplink Pilot Time Slot,上行传输时隙)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SRS(Sounding Reference Symbol,探测参考信号),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中支持的7种上下行子帧配置方式如表1所示。
表1:上下行配置
Figure PCTCN2018097750-appb-000001
现有LTE中控制区域与数据区域的划分如下:
在现有LTE系统中,一个子帧内的下行控制区域占据的时域资源对于所有终端都是相同的。例如对于PDCCH(Physical Downlink Control Channel,物理下行控制信道)而言,下行控制区域所占的时域资源由广播(broadcasting)信道PCFICH(Physical Control Format Indicator Channel,物理控制格式指示信道)决定,UE(User Equipment,用户设备)需要在PCFICH通知的下行控制区域内接收自己的DCI(Downlink Control Information,下行控制信息);对于EPDCCH(Enhanced Physical Downlink Control Channel,增强物理下行控制信道)而言,下行控制区域在时域上占满整个子帧,UE需要在RRC(Radio Resource Control,无线资源控制)配置的PRB set(Physical Resource Block set,物理资源块集合)内接收自己的DCI。因此在LTE系统中,在一个TTI内,所有终端的下行数据信道具有确定的时域起始位置。
在现有LTE系统中,一个TTI内的下行控制区域与数据区域在资源上是相互独立的。下行控制信道在进行映射时占满下行控制区域的整个时域位置。下行数据信道的时间上的起点位置是确定的,即下行数据信道从该TTI内除控制区域外的第一个OFDM(Orthogonal Frequency Division Multiplexing,正交频分复用)符号开始传输或者在不同频域位置的第一个OFDM符号开始传输。当每个终端的用于传输下行控制信道的控制资源集合独立配置,无法预知其他终端的控制资源集合的占用情况,造成终端的下行控制信道传输占用的资源与其他终端的控制资源集合重叠时,无法确定如何进行处理,从而导致下行数据传输效率较低或者可靠性降低。
发明内容

具体实施方式
为了解决上述技术问题,本发明实施例中的技术方案的总体思路如下:
一种用于传输下行数据的资源的确定和配置方法,基于接收到的基站发送的资源配置信息,确定基站为终端配置的用于接收下行数据的第一资源集合或第一资源集合组的第一时频资源位置;基于接收到的基站发送的用于表征所述第一资源集合的全部资源集合或每个资源集合、或第一资源集合组的 全部资源集合子组或每个资源集合子组能否用于传输下行数据的指示信息,确定用于接收下行数据的第二资源集合或者第二资源集合组的第二时频资源位置,其中,所述第一资源集合组包括至少一个资源集合子组,所述至少一个资源集合子组中包括至少一个资源集合。
本发明实施例中的技术方案,基站为每个终端配置用于接收下行数据的资源集合或资源集合子组,然后基站通过显式信令的方式通知终端配置的资源集合全部资源集合或每个资源集合、或资源集合子组的全部资源集合子组或每个资源集合子组是否可用,使得终端根据该通知确定用于接收下行数据的资源的时频资源位置,从而终端能够在该确定的资源上进行速率匹配。
为了更好的理解上述技术方案,下面将结合说明书附图以及具体的实施方式对上述技术方案进行详细的说明。
如图3所示,本发明实施例一提供了一种确定用于接收下行数据的资源的方法,应用于终端侧,所述方法包括:
S101,基于接收到的基站发送的资源配置信息,确定基站为终端配置的用于接收下行数据的第一资源集合或第一资源集合组的第一时频资源位置;
S102,基于接收到的基站发送的用于表征所述第一资源集合的全部资源集合或每个资源集合、或第一资源集合组的全部资源集合子组或每个资源集合子组能否用于传输下行数据的指示信息,确定用于接收下行数据的第二资源集合或者第二资源集合组的第二时频资源位置,其中,所述第一资源集合组包括至少一个资源集合子组,所述至少一个资源集合子组中包括至少一个资源集合。
对于S101,资源配置信息,可以是接收到的基站发送的高层信令中携带的资源配置信息,根据资源配置信息,终端侧能够获得基站为终端配置的用于接收下行数据的第一资源集合或第一资源集合组的时频资源位置。例如,终端接收到高层信令携带的资源配置信息后,终端就获得了基站为终端配置的用于接收下行数据的资源集合或资源集合子组的时频资源位置。
具体地,第一资源集合或第一资源集合组是基站为终端预留的可能用于 传输下行数据(例如下行控制信道)资源集合或资源集合子组。
所述至少一个资源集合中的任一资源集合可以包括至少一个频域上的RB(resource block,资源块)以及时域上的至少一个OFDM符号,或者包括至少一个CCE(Control Channel Element,控制信道单元),或者包括至少一个CCE组,或者包括至少一个PRB(physical resource block,物理资源块)组,或者至少一个RE(resource element,资源单元),或者包括至少一个RE组;
所述第一资源集合组包括至少一个资源集合子组,所述至少一个资源集合子组中包括至少一个资源集合;同样,该至少一个资源集合中的任一资源集合可以包括至少一个频域上的RB以及时域上的至少一个OFDM符号,或者包括至少一个CCE,或者包括至少一个CCE组,或者包括至少一个PRB组,或者至少一个RE,或者包括至少一个RE组。此处对于任一资源集合的具体组成仅仅是举例,但并不限定于以上几种组成方式,任一资源集合也可以由其他粒度的资源组成。
其中,至少一个资源集合子组,通过接收到的基站发送的高层信令中携带的用于对至少一个资源集合进行分组的分组信息获得。具体地,例如基站在发送给终端的高层信令中除了携带上述资源配置信息外,如果该资源配置信息中给终端配置的资源是资源集合子组,那么基站可以根据实际需要,对所述至少一个资源集合进行分组,每个资源集合子组内至少包括一个资源集合。该高层信令中可以携带对所述至少一个资源集合进行分组的分组信息。则终端根据接收到的高层信令中携带的资源配置信息和分组信息,就可以获知基站配置资源的时频资源位置。当然,作为另外一种情况,资源配置信息中除了包括基站为终端配置的资源(例如资源集合或资源集合子组)的时频资源位置,也可以包括对于基站为终端配置的资源的分组信息。
在执行完S101之后,执行S102,对于S102,指示信息的携带可以包括以下几种不同的实现方式:
方式1:终端接收到的基站发送的通过组公共PDCCH携带的指示信息; 具体地,所述组公共PDCCH携带的指示信息用于指示一个或者多个slot(时隙)内基站配置的资源集合的全部资源集合或每个资源集合、或资源集合子组的全部资源集合子组或资源集合子组是否可以用于传输数据。
方式2:终端接收到的基站发送的通过调度数据传输的UE专属DCI携带的指示信息;具体地,所述组公共PDCCH携带的指示信息用于指示一个或者多个slot内基站配置的资源集合的全部资源集合、或资源集合子组的全部资源集合子组是否可以用于传输数据。。
对于方式1,指示信息可以包括如下几种实现方式:
方式1a:接收到的基站发送的通过组公共PDCCH携带的用于表征所述第一资源集合的全部资源集合或第一资源集合组的全部资源集合子组能够用于传输下行数据的指示信息;接收到的基站发送的通过组公共PDCCH携带的用于表征所述第一资源集合的全部资源集合或第一资源集合组的全部资源集合子组不能够用于传输下行数据的指示信息;
方式1b:接收到的基站发送的通过组公共PDCCH中携带的用于表征所述第一资源集合中不能够用于传输下行数据的资源集合和能够用于传输下行数据的资源集合的位图指示信息;
方式1c:接收到的基站发送的通过组公共PDCCH中携带的用于表征所述第一资源集合组中不能够用于传输下行数据的资源集合子组和能够用于传输下行数据的资源集合子组的位图指示信息。
对于方式1a,S102具体为:
若接收到的基站发送的用于表征所述第一资源集合的全部资源集合或第一资源集合组的全部资源集合子组能够用于传输下行数据的指示信息,确定用于接收下行数据的第二资源集合或者第二资源集合组的第二时频资源位置,其中,所述第一时频资源位置和所述第二时频资源位置相同;
若接收到的所述基站发送的用于表征所述第一资源集合的全部资源集合或第一资源集合组的全部资源集合子组不能够用于传输下行数据的指示信息,确定用于接收下行数据的第二资源集合或第二资源集合组的第二时频资 源位置,其中,所述第一时频资源位置和所述第二时频资源位置不同。
具体地,假设通过组公共PDCCH携带的指示信息为1bit的指示信息,该指示信息用于指示终端的用于接收下行数据的时频资源。
该指示信息为1或0,1用于表征所述第一资源集合的全部资源集合或第一资源集合组的全部资源集合子组能够用于传输下行数据,0用于表征所述第一资源集合的全部资源集合或第一资源集合组的全部资源集合子组不能够用于传输下行数据。
若基站为终端配置的预留的资源为第一资源集合(或第一资源集合组),且终端接收到的指示信息为1,则终端确定用于接收下行数据的资源为第一资源集合(或第一资源集合组)。
若基站为终端配置的预留的资源为第一资源集合(或第一资源集合组),且终端接收到的指示信息为0,则终端确定用于接收下行数据的资源为除第一资源集合(或第一资源集合组)的其他资源集合(或资源集合子组)。
然后,终端在确定后的资源集合(或资源集合子组)进行速率匹配。
对于方式1b和方式1c,组公共PDCCH中携带的指示信息,通过bitmap(位图)的方式指示传输下行数据的资源位置,该指示信息为位图指示信息。则S102具体为:
若接收到的基站发送的用于表征所述第一资源集合中不能够用于传输下行数据的资源集合和能够用于传输下行数据的资源的位图指示信息,基于所述位图指示信息,确定用于接收下行数据的第二资源集合的第二时频资源位置,其中,所述第二时频资源位置包括所述第一资源集合中能够用于传输下行数据的资源集合的时频资源位置;
若接收到的基站发送的用于表征所述第一资源集合组中不能够用于传输下行数据的资源集合子组和能够用于传输下行数据的资源集合子组的位图指示信息,基于所述位图指示信息,确定用于接收下行数据的第二资源集合组的第二时频资源位置,其中,所述第二时频资源位置包括所述第一资源集合组中能够用于传输下行数据的资源集合子组的时频资源位置。
具体地,位图指示信息具体例如是bitmap,该bitmap的数据长度由基站通过高层信令为终端配置的资源集合的个数或者资源集合子组的数目确定。例如,基站通过高层信令为终端配置的资源集合的个数或者资源集合子组的数目为Q,则所述bitmap由Q bit组成,每一个bit对应于一个资源集合或者一个资源集合子组。例如bitmap的状态为8位01 000 100,其指示基站通过高层信令为终端配置的第一资源集合(或第一资源集合组)为{1,2,3,4,5,6,7,8},设置bitmap的最高位指示编号为1的资源集合,以此类推,bitmap的最低位指示编号为8的资源集合,1表示该资源集合可用,0表示该资源集合不可用,则bitmap的状态表示,终端可以使用编号为2的资源集合和编号为6的资源集合接收下行数据。
进一步的,终端没有成功接收到所述组公共PDCCH或者由基站配置不需要检测接收组公共PDCCH时,终端按照特定的行为接收数据。具体的,可以认为高层信令配置的所有资源集合或者所有资源集合子组均用于传输下行数据;或者,认为高层信令配置的所有资源集合或者所有资源集合子组均不能用于传输下行数据。
对于方式2,指示信息的实现方式如下:
接收到的基站发送的通过调度数据传输的UE专属DCI携带的用于表征所述第一资源集合或第一资源集合组的全部资源集合能够用于传输下行数据的指示信息;
接收到的基站发送的通过调度数据传输的UE专属DCI携带的用于表征所述第一资源集合或第一资源集合组的全部资源集合不能够用于传输下行数据的指示信息。
对于方式2,S102具体为:
若接收到的基站发送的用于表征所述第一资源集合的全部或第一资源集合组的全部资源集合能够用于传输下行数据的指示信息,确定用于接收下行数据的第二资源集合或者第二资源集合组的第二时频资源位置,其中,所述第一时频资源位置和所述第二时频资源位置相同;
若接收到的所述基站发送的用于表征所述第一资源集合的全部或第一资源集合组的全部资源集合不能够用于传输下行数据的指示信息,确定用于接收下行数据的第二资源集合或第二资源集合组的第二时频资源位置,其中,所述第一时频资源位置和所述第二时频资源位置不同。
具体地,假设通过调度数据传输的UE专属DCI携带的指示信息为1bit的指示信息,该指示信息可以通过1bit的bitmap(位图)的方式或者其他方式来指示终端的用于接收下行数据的时频资源。
该指示信息为1或0,1用于表征所述第一资源集合的全部资源集合或第一资源集合组的全部资源集合子组能够用于传输下行数据,0用于表征所述第一资源集合的全部资源集合或第一资源集合组的全部资源集合子组不能够用于传输下行数据。
若基站为终端配置的预留的资源为第一资源集合(或第一资源集合组),且终端接收到的指示信息为1,则终端确定用于接收下行数据的资源为第一资源集合(或第一资源集合组)。
若基站为终端配置的预留的资源为第一资源集合(或第一资源集合组),且终端接收到的指示信息为0,则终端确定用于接收下行数据的资源为除第一资源集合(或第一资源集合组)的其他资源集合(或资源集合子组)。
为了更好的理解本实施例,基于指示信息的上述几种实现方式对确定用于接收下行数据的资源的方法的实现方式进行具体的举例说明。
实现方式1:假设系统中一共有3个UE,即UE1,UE2,UE3。其中基站为UE1配置了三个CORESET(C1,C2,C3),基站为UE2配置了两个CORESET,基站为UE3配置了4个CORESET。且假设终端UE1,UE2,UE3组成一个UE组,可以接收同一个组公共PDCCH。基站为每个终端配置其下行控制信道对应的CORESET后,还要通过高层信令配置可能用于传输其他终端控制信道的资源集合,基站为终端配置的第一资源集合可以为一个或多个CORESET,也可以是相比于CORESET更小的资源粒度,例如,PRB或者PRB group或者CCE或者CCE group等,基站为终端配置的第一资源集合组 可以包括一个或多个资源集合子组,任一资源集合子组可以包括一个或多个CORESET,同样,也可以是相比于CORESET更小的资源粒度。本发明并不做限定。本实施例中,假设所述资源集合为不同终端的不同CORESET。
本实施例以UE1的角度为例说明本发明的相关技术方案。UE1接收高层信令,接收高层信令中携带的资源集合配置信息,在此例中,基站通过高层信令为UE1配置了9个资源集合,且此处资源集合为不同终端的CORESET。调度UE1数据信道的下行控制信道在CORESET1内传输,且其数据区域内包含了多个其他终端的CORESET。基站在对数据进行接收之前,根据组公共PDCCH中携带的指示信息,确定哪些高层信令配置的CORESET可以用于传输数据。所述指示信息为长度为9bit的bitmap,其中每个信息为对应于特定的CORESET。如图4所示,例如bitmap的最高位指示如图4所示编号为1的CORESET是否用于下行数据传输,第二位指示如图4所示编号为2的CORESET是否用于下行数据传输,以此类推,最低位指示如图4所示编号为9的CORESET是否用于下行数据传输。以下图为例,bitmap的状态为001011101,即CORESET{3 5 6 7 9}的资源可用于下行数据传输,CORESET{12 4 8}不能用于下行数据传输,PDSCH(PDSCH(Physical Downlink Shared CHannel,物理下行共享信道)需要根据这4个CORESET进行速率匹配。
进一步的,此例中RRC为同一终端组中每个终端配置的预留资源集合应当是相同的,且编号应当采用统一的方式,例如,按照先频域后时域的方式进行编号。当然,并不排斥其他编号方式。
进一步的,所述组公共PDCCH携带的指示信息指示一个或者多个slot内高层配置的资源集合是否用于传输数据。同样,多个slot的每个slot中的资源集合的时频资源位置可以是相同的,也可以是不同的。
实现方式2:
如实现方式1所述。假设系统中一共有3个UE,即UE1,UE2,UE3。其中基站为UE1配置了三个CORESET(C1,C2,C3),基站为UE2配置了两个CORESET,基站为UE3配置了4个CORESET。且假设终端UE1,UE2, UE3组成一个UE组,可以接收同一个组公共PDCCH。在本实施例中,基站选择部分CORESET配置给每个终端作为预留的资源集合,并通过组公共PDCCH携带的指示信息进行指示,其中,指示信息为1或0,1用于表征预留的资源集合的全部资源集合能够用于传输下行数据,0用于表征预留的资源集合的全部资源集合不能够用于传输下行数据。例如,以图4为例,基站选择CORESET{1 3 5 7 9}作为预留资源,并将每个CORESET的时频域资源信息通过RRC signaling通知给终端,进一步通过组公共PDCCH进行指示(指示信息为1或0)。
实现方式3:
如实现方式1所示,假设系统中一共有3个UE,即UE1,UE2,UE3。基站通过高层信令的方式,为UE1,UE2,UE3分别配置相同的预留资源集合,例如给UE1,UE2,UE3分别配置了第一资源集合,第一资源集合8个资源集合{1 2 3 4 5 6 7 8}。在此例中,每个资源集合(可以是CORESET)可以包括至少一个PRB group,或者包括至少一个CCE group,或者以至少一个其他粒度的资源,且每个资源集合所包括的CCE group或者PRB group的数目与用于传输下行控制信道的CORESET所占的资源大小无关。并进一步通过组公共PDCCH上承载的速率匹配指示信息(如实现方式1中的bitmap)哪些资源集合可用于数据传输。
实现方式4:
假设系统中存在3个UE。基站通过高层信令为每个终端配置的第一资源集合包括一个或者多个预留资源集合。基站通过组公共PDCCH上携带的指示信息,指示所述高层信令配置的资源集合是否可以用于传输下行数据。在此实施例中,组公共PDCCH携带的指示信息由1bit信息组成,当所述指示bit状态为1时,代表高层信令配置的所有资源集合均可用于传输下行数据;当所述指示bit状态为0时,代表高层信令配置的所有资源集合均不能用于传输下行数据。若指示信息为0,则终端需要确定除所述资源集合的其他能够用于传输下行数据的资源集合,然后进行速率匹配。在此例中,基站为高层信令 为每个终端配置的预留资源集合可以是相同的,也可以是不同的,如图5所示。
另外,本实现方式中的资源集合的含义如实现方式1-3。即可以是CORESET,也可以是其他资源粒度组成的资源集合,在此不做限制。
实现方式5:假设系统中存在3个UE。基站通过高层信令为每个终端配置的第一资源集合包括一个或者多个预留资源集合。基站通过调度UE数据传输的DCI上携带的指示信息,指示所述高层信令配置的资源集合是否可以用于传输数据。在此实施例中调度DCI中携带的指示信息由1bit信息组成,当所述指示bit状态为1时,代表高层信令配置的第一资源集合的所有资源集合均可用于传输数据;当所述指示bit状态为0时,代表高层信令配置的第一资源集合的所有资源集合均不能用于传输数据。若指示信息为0,则终端需要确定除第一资源集合的其他能够用于传输下行数据的资源集合,PDSCH需要在重新确定的资源集合上进行速率匹配。在此例中,基站为高层信令为每个终端配置的预留资源集合可以是相同的,也可以是不同的,如图5所示。
另外,本实现方式中的资源集合的含义如实现方式1-3。即可以是CORESET,也可以是其他资源粒度组成的资源集合,在此不做限制。
对于资源集合子组的实现方式,一资源集合子组可以包括至少一个资源集合子组,一资源集合子组包括至少一个资源集合。对于资源集合子组的指示方式与资源集合的指示方式相同,例如对于资源集合子组中的编号为1-8的资源集合子组{1 2 3 4 5 6 7 8},可以通过bitmap 00101110来指示资源集合子组中的哪些资源组可用,例如bitmap的最高位指示编号为1的CORESET是否用于下行数据传输,第二位指示编号为2的CORESET是否用于下行数据传输,以此类推,最低位指示编号为8的CORESET是否用于下行数据传输,其中1表示可用,0表示不可用,bitmap指示编号为{3 5 6 7}的资源可用于下行数据传输,CORESET{1 2 4 8}不能用于下行数据传输。资源集合子组的实现方式与上述资源集合的实现方式原理相同,在此不再赘述。
如图6所示,本发明实施例二提供了配置用于传输下行数据的资源的方 法,应用于基站侧,所述方法包括:
S201,将资源配置信息发送给终端,使得所述终端获得用于接收下行数据的第一资源集合或第一资源集合组的第一时频资源位置;
S202,将用于表征所述第一资源集合的全部资源集合或每个资源集合、或第一资源集合组的全部资源集合子组或每个资源集合子组能否用于传输下行数据的指示信息发送给终端,使得所述终端根据所述指示信息确定用于接收下行数据的第二资源集合或者第二资源集合组的第二时频资源位置,其中,所述第一资源集合组包括至少一个资源集合子组,所述至少一个资源集合子组中包括至少一个资源集合。
具体地,资源配置信息,可以是基站发送的高层信令中携带的资源配置信息,根据资源配置信息,终端侧能够获得基站为终端配置的用于接收下行数据的第一资源集合或第一资源集合组的时频资源位置。例如,终端接收到高层信令携带的资源配置信息后,终端就获得了基站为终端配置的用于接收下行数据的资源集合或资源集合子组的时频资源位置。
具体地,第一资源集合或第一资源集合组是基站为终端预留的可能用于传输下行数据(例如下行控制信道)资源集合或资源集合子组。
所述至少一个资源集合中的任一资源集合可以包括至少一个频域上的RB以及时域上的至少一个OFDM符号,或者包括至少一个CCE,或者包括至少一个CCE组,或者包括至少一个PRB组,或者至少一个RE,或者包括至少一个RE组;
所述第一资源集合组包括至少一个资源集合子组,所述至少一个资源集合子组中包括至少一个资源集合;同样,该至少一个资源集合中的任一资源集合可以包括至少一个频域上的RB以及时域上的至少一个OFDM符号,或者包括至少一个CCE,或者包括至少一个CCE组,或者包括至少一个PRB组,或者至少一个RE,或者包括至少一个RE组。此处对于任一资源集合的具体组成仅仅是举例,但并不限定于以上几种组成方式,任一资源集合也可以由其他粒度的资源组成。
其中,至少一个资源集合子组,通过接收到的基站发送的高层信令中携带的用于对至少一个资源集合进行分组的分组信息获得。具体地,例如基站在发送给终端的高层信令中除了携带上述资源配置信息外,如果该资源配置信息中给终端配置的资源是资源集合子组,那么基站可以根据实际需要,对所述至少一个资源集合进行分组,每个资源集合子组内至少包括一个资源集合。该高层信令中可以携带对所述至少一个资源集合进行分组的分组信息。则终端根据接收到的高层信令中携带的资源配置信息和分组信息,就可以获知基站配置资源的时频资源位置。当然,作为另外一种情况,资源配置信息中除了包括基站为终端配置的资源(例如资源集合或资源集合子组)的时频资源位置,也可以包括对于基站为终端配置的资源的分组信息。
在执行完S201之后,执行S202,对于S202,指示信息的携带可以包括以下几种不同的实现方式:
方式1:基站发送给终端的通过组公共PDCCH携带的指示信息;具体地,所述组公共PDCCH携带的指示信息用于指示一个或者多个slot内基站配置的资源集合的全部资源集合或每个资源集合、或资源集合子组的全部资源集合子组或资源集合子组是否可以用于传输数据。
方式2:基站发送给终端的通过调度数据传输的UE专属DCI携带的指示信息;具体地,所述组公共PDCCH携带的指示信息用于指示一个或者多个slot内基站配置的资源集合的全部资源集合、或资源集合子组的全部资源集合子组是否可以用于传输数据。
对于方式1,指示信息可以包括如下几种实现方式:方式1a:通过组公共PDCCH携带的用于表征所述第一资源集合或第一资源集合组的全部资源集合能够用于传输下行数据的指示信息;
通过组公共PDCCH携带的用于表征所述第一资源集合或第一资源集合组的全部资源集合不能够用于传输下行数据的指示信息。
方式1b:通过组公共PDCCH中携带的用于表征所述第一资源集合中不能够用于传输下行数据的资源集合和能够用于传输下行数据的资源集合的位 图指示信息;
方式1c:通过组公共PDCCH中携带的用于表征所述第一资源集合组中不能够用于传输下行数据的资源集合子组和能够用于传输下行数据的资源集合子组的位图指示信息。
对于方式1a,S202具体为:
将用于表征所述第一资源集合的全部或第一资源集合组的全部资源集合不能够用于传输下行数据的指示信息发送给终端,使得所述终端根据所述指示信息确定用于接收下行数据的第二资源集合或者第二资源集合组的第二时频资源位置,其中,所述第一时频资源位置和所述第二时频资源位置不同;
将用于表征所述第一资源集合的全部或第一资源集合组的全部资源集合能够用于传输下行数据的指示信息发送给终端,使得所述终端根据所述指示信息确定用于接收下行数据的第二资源集合或者第二资源集合组的第二时频资源位置,其中,所述第一时频资源位置和所述第二时频资源位置相同。
具体地,假设通过组公共PDCCH携带的指示信息为1bit的指示信息,该指示信息用于指示终端的用于接收下行数据的时频资源。
该指示信息为1或0,1用于表征所述第一资源集合的全部资源集合或第一资源集合组的全部资源集合子组能够用于传输下行数据,0用于表征所述第一资源集合的全部资源集合或第一资源集合组的全部资源集合子组不能够用于传输下行数据。
若基站为终端配置的预留的资源为第一资源集合(或第一资源集合组),且终端接收到的指示信息为1,则终端确定用于接收下行数据的资源为第一资源集合(或第一资源集合组)。
若基站为终端配置的预留的资源为第一资源集合(或第一资源集合组),且终端接收到的指示信息为0,则终端确定用于接收下行数据的资源为除第一资源集合(或第一资源集合组)的其他资源集合(或资源集合子组)。
然后,终端在确定后的资源集合(或资源集合子组)进行速率匹配。
对于方式1b和方式1c,组公共PDCCH中携带的指示信息,通过bitmap (位图)的方式指示传输下行数据的资源位置,该指示信息为位图指示信息。则S202具体为:
将用于表征所述第一资源集合中不能够用于传输下行数据的资源集合和能够用于传输下行数据的资源的位图指示信息发送给终端,使得所述终端根据所述指示信息确定用于接收下行数据的第二资源集合或者第二资源集合组的第二时频资源位置,其中,所述第二时频资源位置包括所述第一资源集合中能够用于传输下行数据的资源集合的时频资源位置;
将用于表征所述第一资源集合组中不能够用于传输下行数据的资源集合子组和能够用于传输下行数据的资源集合子组的位图指示信息发送给终端,使得所述终端根据所述指示信息确定用于接收下行数据的第二资源集合或者第二资源集合组的第二时频资源位置,其中,所述第二时频资源位置包括所述第一资源集合组中能够用于传输下行数据的资源集合子组的时频资源位置。
具体地,位图指示信息具体例如是bitmap,该bitmap的数据长度由基站通过高层信令为终端配置的资源集合的个数或者资源集合子组的数目确定。例如,基站通过高层信令为终端配置的资源集合的个数或者资源集合子组的数目为Q,则所述bitmap由Q bit组成,每一个bit对应于一个资源集合或者一个资源集合子组。例如bitmap的状态为8位01 000 100,其指示基站通过高层信令为终端配置的第一资源集合(或第一资源集合组)为{1,2,3,4,5,6,7,8},设置bitmap的最高位指示编号为1的资源集合,以此类推,bitmap的最低位指示编号为8的资源集合,1表示该资源集合可用,0表示该资源集合不可用,则bitmap的状态表示,终端可以使用编号为2的资源集合和编号为6的资源集合接收下行数据。
进一步的,终端没有成功接收到所述组公共PDCCH或者由基站配置不需要检测接收组公共PDCCH时,终端按照特定的行为接收数据。具体的,可以认为高层信令配置的所有资源集合或者所有资源集合子组均用于传输下行数据;或者,认为高层信令配置的所有资源集合或者所有资源集合子组均不能 用于传输下行数据。
