Description

信号资源的指示方法和设备 技术领域
本发明实施例涉及通信技术领域，并且更具体地，涉及信号资源的指示方法和设备。
背景技术
通信系统的物理层设计需要保证用户设备(英文全称:User Equipment，英文缩写:UE)能够准确地进行数据传输，对于上行传输，通信系统的物理层设计包括上行数据信号设计、上行控制信号设计、导频信号的设计、上行信道探测信号的设计等。上行数据信号设计如采用正交频分复用接入(英文全称：Orthogonal Frequency Division Multiple Access，英文缩写:OFDM)信号或SC-FDMA(中文全称：单载波频分多址)信号、导频信号的设计如导频信号的位置和导频信号的密度等。
以3GPP(英文全称：The3rd Generation Partnership Project，中文全称：第三代合作伙伴计划)LTE(英文全称：Long Term Evolution，中文全称：长期演进)系统为例，在上行数据传输的子帧中，一个子帧包括14个符号，其中第4个符号和第11个符号均用来传输DMRS(英文全称：Demodulation Reference Signal，中文全称：解调参考信号)，DMRS用于解调上行数据；14个符号中的一个符号(例如，第14个符号)周期性或按需地用来发送SRS(英文全称：Sounding Reference Signal，中文全称：探测参考信号)，SRS用于测量上行信道质量。
但是，在现有的技术方案中，用户设备传输DMRS和SRS的资源位置是相互独立的，用户设备可能占用了子帧中的3个符号来传输DMRS和SRS，增加额外的系统开销。

可选地，作为另一个实施例，第一参考信号组合占用的资源为第一符号和第二符号，其中第二符号被划分成至少两个资源组，至少两个资源组包括第三资源组和第四资源组。这里，两个符号中只有一个符号划分了资源组。可选地，第一参考信号组合包括DMRS，DMRS占用的资源为第一符号的所有资源以及在第 二符号的第三资源组和第四资源组内。或者，第一参考信号组合包括DMRS，DMRS占用的资源为第一符号的所有资源以及在第二符号的第三资源组内。或者第一参考信号组合包括DMRS和SRS，DMRS占用的资源为第一符号的所有资源，以及SRS占用的资源在第二符号的第三资源组内。等等。
可选地，作为另一个实施例，第一参考信号组合占用的资源为第一符号和第二符号，第一符号和第二符号均被划分成至少两个资源组，第一符号划分的至少两个资源组中包括第一资源组和第二资源组，第二符号划分的至少两个资源组中包括第三资源组和第四资源组。第一参考信号组合包括DMRS，DMRS占用的资源可以在第一资源组和第三资源组内；或者DMRS占用的资源也可以在第一资源组、第二资源组、第三资源组和第四资源组内；或者DMRS占用的资源还可以在第一资源组、第二资源组和第三资源组内。或者，第一参考信号组合包括DMRS和SRS，DMRS占用的资源可以在第一资源组内以及SRS占用的资源在第三资源组内；或者DMRS占用的资源在第一资源组和第二资源组内以及SRS占用的资源在第三资源组内；或者DMRS占用的资源在第一资源组和第三资源组内以及SRS占用的资源在第二资源组内。
可选地，第一符号在子帧的第一时隙上，第二符号在子帧的第二时隙上；第一时隙和第二时隙不同。
可选地，第一符号可以被划分成两个comb资源组，分别是包括奇数子载波的comb资源组和包括偶数子载波的comb资源组。可选地，第一资源组为包括奇数子载波的comb资源组且第二资源组为包括偶数子载波的comb资源组；或者第二资源组为包括奇数子载波的comb资源组且第一资源组为包括偶数子载波的comb资源组。
可选地，第二符号可以被划分成两个comb资源组，分别是包括奇数子载波的comb资源组和包括偶数子载波的comb资源组。可选地，第三资源组为包括奇数子载波的梳型comb资源组且第四资源组为包括偶数子载波的comb资源组；或者第四资源组为包括奇数子载波的comb资源组且第三资源组为包括偶数子载波的comb资源组。
下面结合图2A-2D进行举例说明，在图2A-2D的子帧结构的示意图中，均描绘了一个子帧包括14个符号，14个符号中的第1个符号至第7个符号在子帧的时隙0上，第8个符号至第14个符号在子帧的时隙1上。第一参考信号组合占用的资源为子帧中的第4个符号和/或第11个符号，其中第4个符号被划分 成2个comb资源组，分别是包括偶数子载波的comb资源组comb0和包括奇数子载波的comb资源组comb1，以及第11个符号被划分成2个comb资源组，分别是包括偶数子载波的comb资源组comb0和包括奇数子载波的comb资源组comb1。
例如，如图2A所示，第一参考信号组合包括DMRS和SRS，DMRS和SRS占用的资源为一个子帧中的一个符号(如第4个符号)。可选地，DMRS占用的资源在第4个符号的资源组comb0内且SRS占用的资源在第4个符号的资源组comb1内。
又例如，如图2B所示，第一参考信号组合仅包括DMRS的情况，DMRS占用的资源为一个子帧中的一个符号(如第11个符号)。可选地，DMRS占用的资源在第11个符号的资源组comb0内；或者，DMRS占用的资源在第11个符号的资源组comb1内；或者，DMRS占用的资源在第11个符号的资源组comb0和comb1内。

再例如，如图2D所示，第一参考信号组合仅包括DMRS的情况，DMRS占用的资源为一个子帧中的两个符号(如第4个符号和第11个符号)。可选地，DMRS占用的资源在第4个符号的两个资源组中任一资源组(comb0或comb1)和第11个符号的资源组的两个资源组中任一资源组(comb0或comb1)；或者，DMRS占用的资源在第4个符号的两个资源组和第11个符号的任一资源组(comb0或comb1)内；或者，DMRS占用的资源在第11个符号的两个资源组和第4个符号的任一资源组(comb0或comb1)内。
应理解，上述例子仅仅是示例性的，而非要限制本发明的范围，如第一参考信号组合占用的资源可以是子帧的14个符号中的任意一个或任意两个符号，两个符号可以在子帧的相同时隙上，也可以分别在子帧的不同时隙上。还应理解，本发明实施例对于符号的分组方式也不作限定，两个符号中可以有一个符 号被划分成至少两个资源组，也可以是两个符号均被划分成至少两个资源组。
可选地，作为另一个实施例，在步骤101之前，网络侧设备可以根据预定义的参考信号组合资源配置信息确定第一指示信息。其中参考信号组合资源配置信息包括第一参考信号组合占用的资源和第一指示信息相应的索引(如码点(Code Point))的对应关系。
具体地，网络侧设备预先设计至少一个参考信号组合，并配置至少一个参考信号组合中各个参考信号组合占用的资源，至少一个参考信号组合占用的资源为一个子帧中的一个符号或2个符号，至少一个参考信号组合包括上述第一参考信号组合。在网络侧设备中存储有预定义的参考信号组合资源配置信息，预定义的参考信号组合资源配置信息包括至少一个参考信号组合中各个参考信号组合占用的资源以及相应的索引。可选地，网络侧设备可以将预定义的参考信号组合资源配置信息发送给用户设备，或者，可以在用户设备中均预先设置预定义的参考信号组合资源配置信息。用户设备和网络侧设备可以预先约定对至少一个参考信号组合中各个参考信号组合占用的资源进行索引编号。预定义的参考信号组合资源配置信息中参考信号组合的个数对应第一指示信息的比特位数。
例如，预定义的参考信号组合资源配置信息中包括16个参考信号组合，第一指示信息为4个比特位的指示信息，第一参考信号组合为16个参考信号组合中的一个，预定义的参考信号组合资源配置信息以表格形式可以表示如下：
表1预定义的参考信号组合资源配置信息
索引 第一符号 第二符号
0 DMRS(第一资源组) DMRS(第三资源组)
1 DMRS(第一资源组) DMRS(第四资源组)
2 DMRS(第二资源组) DMRS(第三资源组)
3 DMRS(第二资源组) DMRS(第四资源组)
4 DMRS(第一资源组) SRS(第三资源组)
5 DMRS(第一资源组) SRS(第四资源组)
6 DMRS(第二资源组) SRS(第三资源组)
7 DMRS(第二资源组) SRS(第四资源组)
8 SRS(第一资源组) DMRS(第三资源组)
9 SRS(第一资源组) DMRS(第四资源组)
10 SRS(第二资源组) DMRS(第三资源组)
11 SRS(第二资源组) DMRS(第四资源组)
12 DMRS(第一资源组) NULL
13 DMRS(第二资源组) NULL
14 NULL DMRS(第三资源组)
15 NULL DMRS(第四资源组)
其中，第一符号和第二符号表示帧结构中两个符号，第一符号和第二符号均被划分成至少两个资源组，第一符号划分的至少两个资源组中包括第一资源组和第二资源组，第二符号划分的至少两个资源组中包括第三资源组和第四资源组，NULL表示资源空闲。
当基站确定某个用户设备(用户设备1)的第一参考信号组合包括DMRS和SRS，DMRS占用的资源在第一符号的第一资源组内且SRS占用的资源在第二符号的第四资源组内，在表1所示的预定义的参考信号组合资源配置信息中包括的对应关系中索引为5，基站可以向用户设备1发送包括4个比特位的第一指示信息“0101”(预先约定第一指示信息0101对应索引5)。当基站确定另一个用户设备(用户设备2)的第二参考信号组合包括DMRS和SRS，DMRS占用的资源在第二符号的第三资源组内且SRS占用的资源在第一符号的第二资源组内，在表1所示的预定义的参考信号组合资源配置信息中包括的对应关系中索引为10，基站可以向用户设备2发送包括4个比特位的第一指示信息“1010”(预先约定第一指示信息1010对应索引10)。
可选地，可以限制SRS(或者DMRS)占用的资源在两个符号的某个符号上；或者，限制SRS(或者DMRS)占用的资源在某个类型的资源组(如包括奇数子载波的comb资源组或者包括偶数子载波的comb资源组，也表示采用相同的频率位置)上；或者限制SRS(或者DMRS)占用的资源仅在两个符号中的某个符号的某个资源组上；或者限制DMRS占用的资源需占满某个符号的所有资源；或者限制SRS(或者DMRS)占用的资源仅在时隙0或时隙1上。等等。因此，通过限制SRS或者DMRS占用的资源出现的位置能够相应地减少第一指示信息中比特位的数目。
例如，限制SRS占用的资源在第一符号的第二资源组内，或者在第二符号的第四资源组内，预定义的参考信号组合资源配置信息中包括12个参考信号组合，第一指示信息为4个比特位的指示信息，第一参考信号组合为12个参考信 号组合中的一个，预定义的参考信号组合资源配置信息以表格形式可以表示如下：

索引 第一符号 第二符号
0 DMRS(第一资源组) DMRS(第三资源组)
1 DMRS(第一资源组) DMRS(第四资源组)
2 DMRS(第二资源组) DMRS(第三资源组)
3 DMRS(第二资源组) DMRS(第四资源组)
4 DMRS(第一资源组) SRS(第四资源组)
5 DMRS(第二资源组) SRS(第四资源组)

8 DMRS(第一资源组) NULL
9 DMRS(第二资源组) NULL
10 NULL DMRS(第三资源组)
11 NULL DMRS(第四资源组)
进一步地，还可以限制SRS占用的资源仅在第二符号的第四资源组内，此时，预定义的参考信号组合资源配置信息中包括8个参考信号组合，第一指示信息为3个比特位的指示信息，第一参考信号组合为8个参考信号组合中的一个，预定义的参考信号组合资源配置信息以表格形式可以表示如下：
表3预定义的参考信号组合资源配置信息
索引 第一符号 第二符号
0 DMRS(第一资源组) DMRS(第三资源组)
1 DMRS(第一资源组) DMRS(第四资源组)
2 DMRS(第二资源组) DMRS(第三资源组)
3 DMRS(第二资源组) DMRS(第四资源组)
4 DMRS(第一资源组) SRS(第四资源组)
5 DMRS(第二资源组) SRS(第四资源组)

7 DMRS(第二资源组) NULL
或者，
表4预定义的参考信号组合资源配置信息
Figure PCTCN2014085906-appb-000010
再进一步地，还可以限制当DMRS占用的资源为一个子帧中的2个符号时，DMRS占用的资源采用两个符号的相同的频率位置，例如，第一符号的第一资源组和第二符号的第三资源组均为包括偶数子载波的comb资源组comb0，第一符号的第二资源组和第二符号的第四资源组均为包括奇数子载波的comb资源组comb1。预定义的参考信号组合资源配置信息中包括6个参考信号组合，第一指示信息为3个比特位的指示信息，第一参考信号组合为6个参考信号组合中的一个，预定义的参考信号组合资源配置信息以表格形式可以表示如下：
表5预定义的参考信号组合资源配置信息
索引 第一符号 第二符号
0 DMRS(comb0) DMRS(comb0)
1 DMRS(comb1) DMRS(comb1)
2 DMRS(comb0) SRS(comb1)
3 DMRS(comb1) SRS(comb1)
4 DMRS(comb0) NULL
5 DMRS(comb1) NULL
优选地，在本发明实施例中，预定义的参考信号组合资源配置信息包括4个参考信号组合，第一指示信息为2个比特位的指示信息，第一参考信号组合 为4个参考信号组合中的一个，预定义的参考信号组合资源配置信息可以以表格形式示意性地表示如下：
表6预定义的参考信号组合资源配置信息
Figure PCTCN2014085906-appb-000011
或者，
表7预定义的参考信号组合资源配置信息
Figure PCTCN2014085906-appb-000012
可选地，在上述表1至表7中，第一符号在子帧的第一时隙上，第二符号在子帧的第二时隙上，第一时隙和第二时隙不同，如第一时隙为时隙0，第二时隙为时隙1；或者，第一时隙为时隙1，第二时隙为时隙0。
可选地，在上述表1至表7中，第一资源组为包括奇数子载波的梳型comb资源组且第二资源组为包括偶数子载波的comb资源组，或者第二资源组为包括奇数子载波的comb资源组且第一资源组为包括偶数子载波的comb资源组。或者第三资源组为包括奇数子载波的comb资源组且第四资源组为包括偶数子载波的comb资源组，或者第四资源组为包括奇数子载波的comb资源组且第三资源组为包括偶数子载波的comb资源组。
以表7为例，当基站确定用户设备1的第一参考信号组合包括DMRS和SRS，DMRS占用的资源在第一符号的第一资源组内且SRS占用的资源在第二符号的第三资源组内，在表7所示的预定义的参考信号组合资源配置信息中包括的对应关系中索引为1，基站可以向用户设备1发送包括2个比特位的第一指示信息“01”(预先约定第一指示信息01对应索引1)。当基站确定用户设备2的第二参考信号组合包括DMRS，DMRS占用的资源在第一符号的第二资源组和第二符号的第四资源组内，在表7所示的预定义的参考信号组合资源配置信息中包括的对应关系中索引为2，基站可以向用户设备2发送包括2个比特位的第一指示信息“10”(预先约定第一指示信息10对应索引2)。
假设第一符号在子帧的时隙0上(如子帧的第4个符号)，第二符号在子帧的时隙1上(如子帧的第11个符号)，第一资源组和第三资源组为包括偶数子载波的comb资源组comb0，第二资源组和第四资源组为包括奇数子载波的comb资源组comb1。后续用户设备1在传输上行数据子帧的第4个符号的资源组comb0上传输DMRS，在第11个符号的资源组comb0上传输SRS；用户设备2在传输上行数据子帧的第4个符号的资源组comb1上以及在第11个符号的资源组comb1上传输DMRS。这样，子帧中的第11个符号通过频分复用来区分用户设备1传输的SRS和用户设备2传输的DMRS，使得SRS不会占用子帧中的第3个符号，从而有效地减少系统可能占用的资源，避免额外的系统开销，并且由于SRS所占用的符号不能被用户设备用来传输数据，因此，减少系统开销的同时还能够提高资源利用率。
应理解，上述预定义的参考信号组合资源配置信息的例子及表示形式、索引与参考信号组合的对应关系以及索引与第一指示信息的对应关系等等仅仅是示例性的，而非要限制本发明的范围。
需要指出的是，两个符号中也可以只有一个符号被划分成至少两个资源组，本发明实施例对此并不限定。具体地，可以预先约定两个符号中的某个符号(如第一符号)由DMRS占用且DMRS占用该符号的所有资源，第二符号被划分成至少两个资源组。以预定义的参考信号组合资源配置信息包括4个参考信号组合，第一指示信息为2个比特位的指示信息为例，第一参考信号组合为4个参考信号组合中的一个，预定义的参考信号组合资源配置信息可以以表格形式示意性地表示如下：
表8预定义的参考信号组合资源配置信息
Figure PCTCN2014085906-appb-000013
通过上述方案，参考信号组合能够使得DMRS和SRS相互关联，通过第一指示信息来指示参考信号组合中的信号所占用的资源，参考信号组合占用的资源不超过一个子帧中的两个符号。这样，有效地减少系统可能占用的资源，避免额外的系统开销。另外，本发明实施例通过优化参考信号组合占用资源的情况，限制参考信号组合个数，从而相应地减少了第一指示信息采用的比特数目。
图3是本发明另一个实施例的信号资源的指示方法的流程图。图3的方法由用户设备执行。并且与图1的方法相对应，因此将适当省略与图1的实施例重复的描述。

优选地，预定义的参考信号组合资源配置信息包括4个参考信号组合，第一指示信息为2个比特位的指示信息，第一参考信号组合为4个参考信号组合中的一个。
例如，预定义的参考信号组合资源配置信息如上述表6所示，当用户设备接收到基站发送的第一指示信息为“01”(预先约定第一指示信息01对应索引1)，用户设备通过预定义的参考信号组合资源配置信息中索引和参考信号组合的对应关系确定用户设备传输的第一参考信号组合，用户设备确定索引1对应的第一参考信号组合包括DMRS和SRS，DMRS占用的资源在第一符号的第一资源组和第二资源组内且SRS占用的资源在第二符号的第三资源组内。从表6可以看出，第二符号的第四资源组可以由其它用户设备用来传输DMRS或SRS，第二符号采用频分复用来区分SRS和DMRS，或者区分不同用户设备传输的SRS，使得SRS不会占用子帧中的第3个符号，从而有效地减少系统可能占用的资源，避免额外的系统开销，并且由于SRS所占用的符号不能被用户设备用来传输数据，因 此，减少系统开销的同时还能够提高资源利用率。
又例如，预定义的参考信号组合资源配置信息如上述表7所示，当用户设备接收到基站发送的第一指示信息为“01”(预先约定第一指示信息01对应索引1)，用户设备通过预定义的参考信号组合资源配置信息中索引和参考信号组合的对应关系确定用户设备传输的第一参考信号组合，用户设备确定索引1对应的第一参考信号组合包括DMRS和SRS，DMRS占用的资源在第一符号的第一资源组内且SRS占用的资源在第二符号的第三资源组内。进一步地，假设第一符号在子帧的时隙0上(如子帧的第4个符号)，第二符号在子帧的时隙1上(如子帧的第11个符号)，第一资源组和第三资源组为包括偶数子载波的comb资源组comb0，第二资源组和第四资源组为包括奇数子载波的comb资源组comb1。后续用户设备1在传输上行数据子帧的第4个符号的资源组comb0上传输DMRS，在第11个符号的资源组comb0上传输SRS。因此，第11个符号的资源组comb1可以由其它用户设备用来传输DMRS，即子帧中的第11个符号通过频分复用来区分SRS和DMRS，使得SRS不会占用子帧中的第3个符号，从而有效地减少系统可能占用的资源，避免额外的系统开销，并且由于SRS所占用的符号不能被用户设备用来传输数据，因此，减少系统开销的同时还能够提高资源利用率。
再例如，预定义的参考信号组合资源配置信息如上述表8所示，当用户设备接收到基站发送的第一指示信息为“01”(预先约定第一指示信息01对应索引1)，用户设备通过预定义的参考信号组合资源配置信息中索引和参考信号组合的对应关系确定用户设备传输的第一参考信号组合，用户设备确定索引1对应的第一参考信号组合包括DMRS和SRS，DMRS占用的资源在第一符号的所有资源内且SRS占用的资源在第二符号的第三资源组内。从表8可以看出，第二符号的第四资源组可以由其它用户设备用来传输DMRS或SRS，第二符号采用频分复用来区分SRS和DMRS，或者区分不同用户设备传输的SRS，使得SRS不会占用子帧中的第3个符号，从而有效地减少系统可能占用的资源，避免额外的系统开销，并且由于SRS所占用的符号不能被用户设备用来传输数据，因此，减少系统开销的同时还能够提高资源利用率。
当然，当采用其它预定义的参考信号组合资源配置信息时，同一个符号也可以采用频分复用来区分不同用户设备传输的SRS。应理解，本发明实施例对此并不限定。
还应理解，上述预定义的参考信号组合资源配置信息的例子及表示形式、 索引与参考信号组合的对应关系以及索引与第一指示信息的对应关系等等仅仅是示例性的，而非要限制本发明的范围。
通过上述方案，参考信号组合能够使得DMRS和SRS相互关联，通过第一指示来确定参考信号组合中的信号所占用的资源，参考信号组合占用的资源不超过子帧中的两个符号，这样，有效地减少系统可能占用的资源，避免额外的系统开销。另外，本发明实施例通过优化参考信号组合占用资源的情况，限制参考信号组合个数，从而相应地减少了第一指示信息采用的比特数目。
