Description

数据传输、数据处理方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种数据传输、数据处理方法及装置。
背景技术
长期演进(Long Term Evolution，简称为LTE)系统的上行链路中，物理上行共享信道(Physical Uplink Shared Channel，简称为PUSCH)的传输方式采用的正交频分多址(Orthogonal Frequency Division Multiple Access，简称为OFDMA)技术。
在LTE R10版本以前，PUSCH上，每个用户使用系统分配的一段连续时频域资源(Resource Element，简称为RE，资源单元)作为自己的数据传输和导频传输频带。其中RE的时域索引是符号索引，频域索引是子载波索引，数据和导频占用不同索引的符号、相同索引的子载波。在LTE R10版本中引入了非连续RB分配模式，在R10协议中，将一段连续的RB称为簇(cluster)，通常在非连续RB分配模式下，支持多个cluster。单组成载波(Component Carriers，简称CC)支持2个cluster。载波聚合下n个CC最大支持2n个cluster。其中，cluster的大小和位置由对应的调度控制信息通过下行信道下发给对应的UE，一个cluster的最小资源块(Resource Block，简称为RB)数与带宽相关。
相关技术中，PUSCH的导频占用的频域REs和数据占用的频域REs相同，在给定的时频域资源上，对于编码后的数据，每个天线端口分别进行RE映射和SC-FDMA信号生成，来实现发射数据的过程。具体发射过程在3GPP TS 36.211V10.1.0中有详细描述，图1是根据相关技术中的LTE上行物理信道发端处理示意图，如图1所示。
相关技术中，单CC上，PUSCH必须在一个或两个连续RB段上发送，对于空闲的总RB数能够满足传输带宽要求，但是空闲的最大两端连续RB段也不满足终端所需RB数的场景，现有技术不能直接进行该数据的调度与发射，即不能最大化的利用系统空闲资源。
针对相关技术中数据传输存在的资源利用率低的问题，目前尚未提出有效的解决方案。

第三接收模块84，设置为接收终端根据该RB资源信息以及预先接收到的当前可用RB资源确定的用于传输数据的RB资源传输的数据。
下面结合可选实施例对本发明实施例进行进一步说明。
本发明可选实施例提供了一种上行链路数据发射方法，图9是根据本发明实施例的上行物理信道发端处理示意图，如图9所示，包括：基站通过下行信道告诉终端当前系统可用的RB资源索引集合，且终端正确解析该信息并反馈给基站。高层给终端分配用于传输数据的调度信息(其中包括RB资源)。终端按照高层分配到的调度信息对要发送的数据进行数据编码。对数据编码后的数据按照天线端口进行RE映射、二次RE映射和SC-FDMA信号生成，其中，二次RE映射与本发明实施例中指出的二次映射相当。
本实施例中，高层给终端分配用于传输数据的调度信息中，RB的索引均是可用的RB资源索引集合中对应的索引。RE映射，是将编码后的数据映射到可用RB资源集合中分配给该终端的RB资源位置。二次RE映射是将可用RB资源集合中每个RB的数据映射到系统的RB资源对应位置。
本可选实施例提供了一种上行链路数据发射装置，包括：可用的RB资源获取模块、调度消息获取模块、数据编码模块、二次RE映射模块以及SC-FDMA信号生成模块，上述模块的功能由本发明实施例的第一接收模块42、确定模块44、数据传输模块46、发送模块82以及第三接收模块84中的部分或全部实现。
可用的RB资源获取模块，终端通过解析下行信道发送过来的数据，得到基站发来的可用RB资源集合的信息。
调度消息获取模块，通过解析下行信道发送过来的数据，得到基站发来的分配给该终端，用于传输数据的RB资源和其他调度参数。
数据编码模块，设置为对发射的数据进行编码。RE映射模块，设置为将编码后的数据映射到可用RB资源集合中分配给该终端的RB资源位置。
二次RE映射模块，设置为将分配给该终端的RB资源上的数据，映射到系 统的RB资源的对应位置。
SC-FDMA信号生成模块，设置为将系统的RB数据生成IQ数据。
通过本可选实施例，PUSCH可以更加灵活的在RB上进行数据发送，解决了相关技术中PUSCH的RB资源利用率低的问题。
实施例一
本优选实施例以一个应用了本发明提出的上行链路数据发射方法和装置的LTE系统为例进行说明。
假设系统的配置的系统带宽是5MHz，共有25个RB(每个RB有对应的索引，最小值为0，最大值为24)用于数据的传输。在一次下行数据传输中，基站通过下行信道通知终端可用的RB资源索引集合，记作Valid_RBset＝{0,1,2,3,4,5,6,7,8,9,15,16,17,18,20,21,22,23,24}，表示系统RB中，Valid_RBset内的索引都是可用的，否则不可用。Valid_RBset中每个值的索引记作Valid_RBsetIdx＝{0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18}。其中，Valid_RBset中的值表示该索引对应的系统RB可以用于数据传输，否则不可用于数据传输。在该Valid_RBset生效后，终端的所有发射过程都将按照该Valid_RBset进行二次RE映射。
在该Valid_RBset生效后，在一次下行数据传输中，基站通过下行信道通知终端在PUSCH上进行上行数据发射的调度消息，其中的RB索引均是Valid_RBsetIdx中的值，其中为RB起始位置为5，RB数为10，则该终端分配到的RB资源对应的Valid_RBsetIdx中的值是S1＝{5,6,7,8,9,10,11,12,13,14}，对应的Valid_RBset中的值是S2＝{5,6,7,8,9,15,16,17,18,20}。
数据编码后的数据做RE映射时，需要将编码后的数据映射到Valid_RBsetIdx集合的子集S1中。二次RE映射，需要将S1中对应的数据映射到Valid_RBset的对应位置，即S2中。
数据编码和SC-FDMA信号生成两个过程和现有LTE中的方案一致。
实施例二
本可选实施例以一个应用了本发明提出的上行链路数据发射方法和装置的LTE系统为例进行说明。
假设系统的配置的系统带宽是5MHz，共有25个RB(每个RB有对应的索引，最小值为0，最大值为24)用于数据的传输。在一次下行数据传输中，基站通过下行信道通知终端可用的RB资源索引，记作Valid_RBset＝{2,3,4,5,6,9,15,16,17,18,20,21,22,23,24}，表示系统RB中，Valid_RBset内的索引都是可用 的，否则不可用。Valid_RBset中每个值的索引记作Valid_RBsetIdx＝{0,1,2,3,4,5,6,7,8,9,10,11,12,13,14}。其中，Valid_RBset中的值表示该索引对应的系统RB可以用于数据传输，否则不可用于数据传输。在该Valid_RBset生效后，终端的所有发射过程都将按照该Valid_RBset进行二次RE映射。
在该Valid_RBset生效后，在一次下行数据传输中，基站通过下行信道通知终端在PUSCH上进行上行数据发射的调度消息，其中的RB索引均是Valid_RBsetIdx中的值，其中RB资源是在两个cluster上，第一个cluster对应的RB起始位置为2，RB数为4，第二个cluster对应的RB资源起始位置为8，RB数为6，则该终端分配到的RB资源对应的Valid_RBsetIdx中的值是S1＝{2,3,4,5,8,9,10,11,12,13}，对应的Valid_RBset中的值是S2＝{4,5,6,9,17,18,20,21,22,23}。
数据编码后的数据做RE映射时，需要将编码后的数据映射到Valid_RBsetIdx集合的子集S1中。二次RE映射，需要将S1中对应的数据映射到Valid_RBset的对应位置，即S2中。
数据编码和SC-FDMA信号生成两个过程和LTE R10及以后版本中的方案一致。
