Description

一种UE、基站中增强的载波聚合中的调度方法和设备 技术领域
本发明涉及CA(Carrier Aggregation，载波聚合)调度的方案，特别是涉及基于LTE(Long Term Evolution，长期演进)系统的CA调度的方案。
背景技术
传统的3GPP(3rd Generation Partner Project，第三代合作伙伴项目)制定的LTE系统R(Release，版本)10中，CA作为关键技术之一被引入，其核心思想是用户设备(UE-User Equipment)能够同时工作在多个载波上，CA能够提高单个UE的峰值速率。LTE CA中，UE被配置一个Pcell(Primary Cell，主服务小区)，一个或者多个Scell(Secondary Cell，辅服务小区)。对于FDD(Frequency Duplex Division，频分双工)LTE，一个服务小区包括{一个下行载波，一个上行载波}中的至少一个下行载波。对于TDD(Time Duplex Division，时分双工)LTE，一个服务小区包括一个载波。LTE R10中，支持CA的UE最多能够被配置5个服务小区，且UE只能在Pcell上发送PUCCH信息。
现有LTE系统中，CA支持跨载波调度，即基站在第一载波发送下行信令调度第二载波上的无线信号传输。基站利用DCI(Downlink Control Information，下行控制信息)中的CIF(Carrier Indicator Field，载波指示域)指示所要调度的目标载波。CIF由位于DCI头部的3个比特指示。
在3GPP RAN(Radio Access Network，无线接入网)第66次全会(Plenary)通过了一个新的研究课题(RP-142286)，即增强CA。增强CA课题中，最大支持的服务小区数上升到32个。
对于增强CA，一个直观的方法是增加CIF的比特数(例如增加到5比特)以确保基站能够调度到任意目标载波。然而，上述直观的方法导致DCI总比特数的增加，进而导致DCI占用更多的空口资源或者是导致DCI接收性能的下降。针对该问题，本发明公开了一种增强的载波聚合中的调度方法和装置。
发明内容
现有的LTE系统中，基站通过高层信令为UE配置服务小区的小区索引(0到7的整数)，所述小区索引是独一无二的且直接对应于DCI中的CIF。发明人通过研究发现，增强CA场景下，受限于PDCCH(Physical Downlink Control Channel，物理下行控制信道)容量的限制，一个载波上可能很难调度过多的载波。因此，当UE被配置了大量载波时，所述大量载波由多个调度载波上的DCI所调度，即一个调度载波只需要传输用于调度部分载波的DCI。
根据上述分析，本发明公开了一种UE中的方法，其中,包括如下步骤：
-步骤A.接收高层信令确定K组配置信息，所述K组配置信息和K个服务小区一一对应，所述配置信息包括第一索引，第二索引，第三索引，工作频带信息
-步骤B.在第一服务小区上接收第一信令，第一信令包括第四索引和调度信息
-步骤C.根据第一组配置信息和第一信令中的第四索引确定第二服务小区，根据第一信令中的调度信息在第二服务小区上传输无线信号。
其中，第一信令是物理层信令，所述传输是接收或者发送，第一服务小区和第二服务小区分别是所述K个服务小区中的一个。第一组配置信息是第一服务小区对应的所述配置信息，第二组配置信息是第二服务小区对应的所述配置信息。所述K组配置信息中的第一索引是独一无二的。第三索引的比特数小于第一索引的比特数。第二组配置信息是所述K组配置信息中满足如下条件的一组所述配置信息：
-.第二索引的值等于第一组配置信息中的第一索引的值；
-.第三索引的值等于第一信令中的第四索引的值。
所述K组配置信息中的第一索引是独一无二的，即第一索引是所述配置信息的识别索引。第二索引对应调度服务小区的第一索引。第三索引对应调度服务小区上的DCI中的第四索引。
上述方法的本质是：被给定DCI所调度的服务小区在所述给定DCI 中的第四索引的值同所述给定DCI的发送服务小区相关。所述给定DCI的第四索引仅需指示所述发送服务小区所调度的服务小区即可，而不需指示UE被配置的所有服务小区，因此降低了指示第四索引所需的比特数。
作为一个实施例，第二组配置信息存在且唯一。作为一个实施例，所述K是大于5的正整数。作为一个实施例，所述工作频带信息是以下之一：
-.一个载波的中心频点和带宽，或者一个载波的上频点和下频点。所述一个载波用于下行传输，或者同时用于下行和上行传输。
-.两个载波各自的中心频点和带宽，或者两个载波各自的上频点和下频点。所述两个载波分别用于下行传输和上行传输。
作为一个实施例，所述K个服务小区是活动的(Active)。作为一个实施例，所述高层信令是RRC(Radio Resource Control，无线资源控制)信令。作为一个实施例，第二服务小区是第一服务小区。
具体的，根据本发明的一个方面，第二组配置信息还包括第五索引，第一信令是用于调度下行信号的物理层信令，所述传输是接收，第二服务小区的关联PUCCH位于第三服务小区上，第三服务小区是所述K个服务小区中的一个，第三服务小区的配置信息是第三组配置信息，第三组配置信息是所述K组配置信息中第一索引的值等于第二组配置信息的第五索引的值的那组配置信息。
第二服务小区的关联PUCCH是指：第二服务小区上承载的下行无线信号对应的HARQ_ACK所占用的PUCCH，以及反映第二服务小区的CSI(Channel Status Information，信道状态指示)所占用的PUCCH。作为一个实施例，所述CSI包括{PTI(Precoding Type Indicator，预编码类型指示)，RI(Rank Indicator，秩指示)，PMI(Precoding Matrix Indicator，预编码矩阵指示)，CQI(Channel Quality Indicator，信道质量指示)}中的一种或者多种。
作为一个实施例，所述K组配置信息都包括第五索引。作为一个实施例，第三服务小区是第二服务小区。作为一个实施例，第三服务小区是第一服务小区。
具体的，根据本发明的一个方面，第四索引由第一信令中的3个比 特指示。
作为一个实施例，第四索引重用第一信令中的CIF比特。
具体的，根据本发明的一个方面，第一索引和第二索引分别由5个比特指示。
作为一个实施例，第三索引诱3个比特指示。
本发明公开了一种基站中的方法，其中，包括如下步骤：
-步骤A.发送高层信令指示K组配置信息，所述K组配置信息和K个服务小区一一对应，所述配置信息包括第一索引，第二索引，第三索引，工作频带信息
-步骤B.在第一服务小区上发送第一信令，第一信令包括第四索引和调度信息
-步骤C.根据第一信令中的调度信息在第二服务小区上操作无线信号，第二服务小区由第一组配置信息和第一信令中的第四索引指示。
其中，第一信令是物理层信令，所述操作是发送或者接收，第一服务小区和第二服务小区分别是所述K个服务小区中的一个。第一组配置信息是第一服务小区对应的所述配置信息，第二组配置信息是第二服务小区对应的所述配置信息。所述K组配置信息中的第一索引是独一无二的。第三索引的比特数小于第一索引的比特数。第二组配置信息是所述K组配置信息中满足如下条件的一组所述配置信息：
-.第二索引的值等于第一组配置信息中的第一索引的值；
-.第三索引的值等于第一信令中的第四索引的值。

对于基站N1，在步骤S11中，发送高层信令指示K组配置信息，所述K组配置信息和K个服务小区一一对应，所述配置信息包括第一索引，第二索引，第三索引，工作频带信息。在步骤S12中，在第一服务小区上发送第一信令，第一信令包括第四索引和调度信息。在步骤S13中，根据第一信令中的调度信息在第二服务小区上发送第一无线信号。在步骤S14中，根据第一信令中的调度信息在第二服务小区上接收第二无线信号。
对于UE U2，在步骤S21中接收所述高层信令，在步骤S22中接收第一信令。在步骤S23中，根据第一组配置信息和第一信令中的第四索引确定第二服务小区，根据第一信令中的调度信息在第二服务小区上接收无线信号。在步骤S24中，根据第一组配置信息和第一信令中的第四索引确定第二服务小区，根据第一信令中的调度信息在第二服务小区上发送无线信号。
实施例1中，第一信令是物理层信令，第一服务小区和第二服务小区分别是所述K个服务小区中的一个。第二服务小区由第一组配置信息和第一信令中的第四索引指示。第一组配置信息是第一服务小区对应的所述配置信息，第二组配置信息是第二服务小区对应的所述配置信息。所述K组配置信息中的第一索引是独一无二的。第三索引的比特数小于第一索引的比特数。第二组配置信息是所述K组配置信息中满足如下条件的一组所述配置信息：

-.第三索引的值等于第一信令中的第四索引的值。
作为实施例1的子实施例1，第一信令是用于调度下行无线信号的DCI， 即第一信令的DCI格式是格式{1，1A，1B，1C，1D，2，2A，2B，2C，2D}中的一种或者新定义的DCI格式，F1方框标识的步骤(即步骤S13，S23)存在，而F2方框标识的步骤(即步骤S14，S24)不存在。
作为实施例1的子实施例2，第一信令是用于调度上行无线信号的DCI，即第一信令的DCI格式是格式{0，4}中的一种或者新定义的DCI格式，F1方框标识的步骤(即步骤S13，S23)不存在，而F2方框标识的步骤(即步骤S14，S24)存在。
作为实施例1的子实施例3，所述高层信令是RRC信令。
作为实施例1的子实施例4，第四索引由第一信令中的3个比特指示。
实施例2
实施例2示例了调度信令和PUCCH的分布示意图，如附图2所示。附图2中，标识A和C的箭头指示下行调度信令，标识B和D的箭头指示PUCCH传输。
基站发送高层信令给目标UE，所述高层信令指示(K1+K2)组配置信息，所述(K1+K2)组配置信息和(K1+K2)个服务小区一一对应，所述配置信息包括第一索引，第二索引，第三索引，工作频带信息。所述(K1+K2)个服务小区对应附图2中的服务小区#1～#(K1+K2)。对于服务小区#1～#(K1+K2)，对应的配置信息的第一索引分别是0，1，...，K1+K2-1。
对于所述目标UE，服务小区#1～#K1对应的配置信息的第二索引均为0(等于服务小区#1的配置信息的第一索引)，即服务小区#1～#K1都由服务小区#1上所承载的下行信令所调度，如箭头A(1_1)，A(1_2)，...，A(1_K1)所示。
对于所述目标UE，服务小区#(K1+1)～#(K1+K2)对应的配置信息的第二索引均为K1(等于服务小区#K1的配置信息的第一索引)，即服务小区#(K1+1)～#(K1+K2)都由服务小区#K1上所承载的下行信令所调度，如箭头C(1_1)，C(1_2)，...，C(1_K2)所示。
基站在服务小区#1发送第一信令给所述目标UE，第一信令包括第四索引和调度信息。所述目标UE在所述(K1+K2)组配置信息中搜索第二索引等于0且第三索引等于第一信令中的第四索引的配置信息，相应的服务小区即是第一信令的所要调度的目标服务小区-第二服务小区。
考虑到服务小区#1上的控制信令只能调度服务小区#1～#K1，第四索引只要能区分K1个服务小区即可(而用不着区分K1+K2个服务小区)，因此第四索引的指示比特数小于第一索引的指示比特数。
作为实施例2的子实施例1，所述配置信息还包括第五索引，第五索引指示关联PUCCH所属的服务小区。服务小区#1～#K1对应的配置信息的第五索引均为0(等于服务小区#1的配置信息的第一索引)，即服务小区#1～#K1的关联PUCCH都位于服务小区#1上，如箭头B(1_1)，B(2_1)，...，B(K1_1)所示。目标服务小区的关联PUCCH用于承载：
-.针对所述目标服务小区上接收到的下行物理层数据的HARQ_ACK
-.针对所述目标服务小区上的CSI(基于所述目标服务小区所承载的下行RS进行测量而得到)。
作为实施例2的子实施例2，所述配置信息还包括第五索引，第五索引指示关联PUCCH所属的服务小区。服务小区#(K1+1)～#(K1+K2)对应的配置信息的第五索引均为K1+1(等于服务小区#K1+2的配置信息的第一索引)，即服务小区#(K1+1)～#(K1+K2)的关联PUCCH都位于服务小区#K1+2上，如箭头D(1_2)，D(2_2)，...，D(K2_2)所示。

实施例3中，第一信令是物理层信令，所述传输是接收或者发送(如果是发送，第一处理模块203上的双向箭头为向左的输出箭头；如果是接收，第一处理模块203上的双向箭头为向右的输入箭头)，第一服务小区和第二服务小区分别是所述K个服务小区中的一个。第一组配置信息是第一服务小区对应的所述配置信息，第二组配置信息是第二服务小 区对应的所述配置信息。所述K组配置信息中的第一索引是独一无二的。第三索引的比特数小于第一索引的比特数。第二组配置信息是所述K组配置信息中满足如下条件的一组所述配置信息：
