本公开涉及通信技术领域，具体而言，涉及资源元素群组捆确定方法、资源元素群组捆映射方法、资源元素群组捆确定装置、资源元素群组捆映射装置、通信装置和计算机可读存储介质。
背景技术
目前，LTE(Long Term Evolution，长期演进)系统与NR(New Radio，新空口)系统可以在相同的频谱共存。LTE系统需要持续发送CRS(Cell-specific Reference Signal，小区传输参考信号)，这对NR系统会造成强烈的干扰。
在相关技术中，终端在检测NR PDCCH(Physical Downlink Control Channel，物理下行控制信道)的过程中，需要以资源元素群组捆REG bundle为粒度进行信道评估，目前REG bundle到REG(Resource Element Group，资源元素群组)的映射方式，是按照先时域后频域的顺序进行REG bundle到REG的映射。
但是由于LTE CRS的存在，相关技术中的终端在存在LTE CRS的RE(Resource Element，资源元素)上不能传输NR PDCCH DMRS(Demodulatin Reference Signal，解调参考信号)，这可能导致在一个REG bundle中，不同REG上用于信道估计的NR PDCCH DMRS对应RE数量不同，从而影响信道估计的准确性。

图1是根据本公开的实施例示出的一种资源元素群组捆确定方法的示意流程图。本实施例所示的资源元素群组捆方法可以由终端执行，所述终端可以与网络侧设备通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置，所述网络侧设备包括但不限于4G、5G、6G等通信系统中的网络侧设备，例如基站、核心网等。
如图1所示，所述资源元素群组捆确定方法可以包括以下步骤：
在步骤S101中，根据控制资源集CORESET中长期演进小区专属参考信号LTE CRS的分布情况，确定资源元素群组捆REG bundle到REG的映射方式；
在步骤S102中，根据所述映射方式在所述CORESET中确定REG bundle。
图2是根据本公开的实施例示出的一种LTE CRS分别示意图。
在一个实施例中，以LTE小区的标识(Cell ID)等于0，LTE CRS支持4个端口为例，分别为天线端口0、天线端口1、天线端口2和天线端口3。每个天线端口对应的LTE CRS分别占用不同的资源，4个天线端口对应的LTE CRS占用的资源叠加在一起作为第一资源。
如图2所示，在一个RB(Resource Block，资源块)中，时域上包含14个符号(例如正交频分复用OFDM符号)，频域上包含12个RE(Resource Element，资源元素)。例如在一个符号上，RE从下到上的编号为RE#0至RE#11，如图2所示，LTE CRS占用的资源包括第1个、第2个、第5个、第8个、第9个和第12个符号上，编号为RE#0、RE#3、RE#6、RE#9的RE。
需要说明的是，LTE CRS可以由LTE网络侧设备发送，但是NR网络侧设备也可以确定LTE CRS占用的资源，例如可以通过与LTE网络侧设备通信确定，例如也可以是基于协议约定确定的。另外，终端也可以确定LTE CRS占用的资源，例如终端可以基于协议约定确定LTE CRS占用的资源。
图3是根据本公开的实施例示出的一种NR PDCCH DMRS与LTE CRS冲突的示意图。如图3所示，在NR中的资源元素组REG(Resource Element Group)中，NR PDCCH DMRS的图案pattern为NR PDCCH DMRS分布在RE#1、RE#5和RE#9。
例如CORESET的持续长度duration为3个时域符号，例如为RB中的前3个符号，那么在NR PDCCH DMRS位于CORESET中时，在RB中前2个符号的RE#9上，NR PDCCH DMRS与LTE CRS冲突，在冲突的RE上就只发送LTE CRS，而不 发送NR PDCCH DMRS。
图4是根据本公开的实施例示出的一种REG bundle到REG的映射示意图。
在图3所示的情况下，由于相关技术中按照先时域后频域的顺序进行REG bundle到REG的映射，也即先从频域上将REG bundle映射到REG，后从时域上将REG bundle映射到REG。
如图4所示，例如REG bundle的大小为3，也即映射3个REG，按照先时域后频域的顺序进行REG bundle到REG的映射时，会先从CORESET的第一个符号开始向REG映射，然后沿着时域继续向REG映射，直至CORESET的最后一个符号。由于CORESET duration为3个符号，在一个RB中可以完整映射一个REG bundle，例如RB#n中前3个符号对应的REG映射了REG bundle#n。以此类推，RB#n+1中前3个符号对应的REG映射了REG bundle#n+1，RB#n+2中前3个符号对应的REG映射了REG bundle#n+2，REG bundle#n+1和REG bundle#n+2图中并未示出。
当然，以上实施例只是REG bundle的大小为3的情况，若REG bundle的大小为6，那么按照先时域后频域的顺序进行REG bundle到REG的映射时，会先从CORESET的第一个符号开始向REG映射，然后沿着时域继续向REG映射，直至CORESET的最后一个符号。由于CORESET duration为3个符号，所以在一个RB中并不能完整映射一个REG bundle，那么后续可以考虑时域，也即在下一个RB的前3个符号上继续映射REG bundle，从而在2个RB中可以完整映射一个REG bundle。例如在图4所示实施例的情况下，就是RB#n和RB#n+1两个RB的前3个符号上映射一个REG bundle。
基于上述实施例可知，无论REG bundle的大小为多少，按照先时域后频域的顺序进行REG bundle到REG的映射后，REG bundle中前2个符号中NR PDCCH DMRS对应RE数量与REG bundle中第3个符号中NR PDCCH DMRS对应RE数量不同，从而导致REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同，这会导致基于REG bundle进行信道估计的准确性降低。
在一个实施例中，所述映射方式包括以下至少之一：
方式一：按照先时域后频域的顺序进行REG bundle到REG的映射；
方式二：按照先频域后时域的顺序进行REG bundle到REG的映射。
在一个实施例中，所述LTE CRS的分布情况包括以下至少之一：
在所述CORESET中全部时域符号上均分布有LTE CRS；
在所述CORESET中全部时域符号上均未分布LTE CRS；
在所述CORESET中部分时域符号上分布有LTE CRS(另一部分时域符号上未分布有LTE CRS)。
在一个实施例中，基于LTE CRS的分布情况，可以确定沿用已有的映射方式(例如方式一)进行REG bundle到REG的映射是否会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况，如果不会出现这种情况，那么可以基于沿用方式一，如果会出现这种情况，可以改为按照方式二进行映射。
而LTE CRS的分布情况与是否会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况之间的关系可以是预先确定的。例如，在所述CORESET中全部时域符号上均分布有LTE CRS时，或者在所述CORESET中全部时域符号上均未分布LTE CRS时，不会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况(也即REG bundle中不同REG上NR PDCCH DMRS对应RE数量相同)；在所述CORESET中部分时域符号上分布有LTE CRS时，则会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况。
所以终端可以针对会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况时，对应CORESET中LTE CRS的分布情况，确定按照方式二进行映射；针对不会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况时，对应CORESET中LTE CRS的分布情况，确定按照方式一进行映射
因此，根据本公开的实施例，终端可以根据CORESET中LTE CRS的分布情况(例如LTE CRS RE的分布)，确定REG bundle到REG的映射方式，有利于避免REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况。进而根据所述映射方式在所述CORESET中确定REG bundle，根据REG bundle进行信道估计，就可以在REG bundle中每个REG上NR PDCCH DMRS对应RE数量相同的情况下进行信道估计，有利于确保信道估计的准确性。
以上实施例主要描述了有关LTE CRS与NR PDCCH DMRS冲突的情况，LTE CRS与NR PDCCH也会产生冲突。在LTE CRS与NR PDCCH冲突的情况下，可以根据LTE CRS对应RE对NR PDCCH进行打孔，或者根据LTE CRS对应RE对NR PDCCH进行速率匹配(Rate Matching，RM)。
图5是根据本公开的实施例示出的另一种资源元素群组捆确定方法的示意流程图。如图5所示，所述根据控制资源集CORESET中长期演进小区专属参考信号LTE CRS的分布情况，确定资源元素群组捆REG bundle到REG的映射方式包括：
在步骤S501中，在所述CORESET中全部时域符号上均分布有LTE CRS时，确定所述映射方式包括所述方式一。
在一个实施例中，在所述CORESET中全部时域符号上均分布有LTE CRS时，那么每个REG上都存在LTE CRS，而每个REG上与LTE CRS存在冲突的NR PDCCH DMRS对应的RE对应RE数量是相同的，相当于在每个REG上都减少了相同数量的用于传输NR PDCCH DMRS的RE，所以REG bundle中不同REG上NR PDCCH DMRS对应RE数量仍然是相同的，也即不会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况。
因此，可以沿用相关技术中的映射方式，也即方式一，按照先时域后频域的顺序进行REG bundle到REG的映射，在确保REG bundle中不同REG上NR PDCCH DMRS对应RE数量相同的基础上，可以减少对现有协议的调整。
图6是根据本公开的实施例示出的又一种资源元素群组捆确定方法的示意流程图。如图6所示，所述根据控制资源集CORESET中长期演进小区专属参考信号LTE CRS的分布情况，确定资源元素群组捆REG bundle到REG的映射方式包括：
在步骤S601中，在所述CORESET中全部时域符号上均未分布LTE CRS时，确定所述映射方式包括所述方式一。
在一个实施例中，在所述CORESET中全部时域符号上均未分布有LTE CRS时，那么每个REG上都不存在LTE CRS，而每个REG上原本NR PDCCH DMRS对应的RE对应RE数量就是相同的，所以REG bundle中不同REG上NR PDCCH DMRS对应RE数量也就是相同的，那么不会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况。
因此，可以沿用相关技术中的映射方式，也即方式一，按照先时域后频域的顺序进行REG bundle到REG的映射，在确保REG bundle中不同REG上NR PDCCH DMRS对应RE数量相同的基础上，可以减少对现有协议的调整。
图7是根据本公开的实施例示出的又一种资源元素群组捆确定方法的示意流程图。如图7所示，所述根据控制资源集CORESET中长期演进小区专属参考信号LTE  CRS的分布情况，确定资源元素群组捆REG bundle到REG的映射方式包括：
在步骤S701中，在所述CORESET中部分时域符号上分布有LTE CRS时，确定所述映射方式包括所述方式二。
在一个实施例中，在所述CORESET中部分时域符号上分布有LTE CRS时，另一部分时域符号上未分布有LTE CRS，那么在分布有LTE CRS的时域符号对应的REG上，减少了用于传输NR PDCCH DMRS的RE对应RE数量，而在未分布有LTE CRS的时域符号对应的REG上，并未减少用于传输NR PDCCH DMRS的RE对应RE数量，从而REG bundle中在分布有LTE CRS的时域符号对应的REG上和未分布有LTE CRS的时域符号对应的REG上，NR PDCCH DMRS对应RE数量不同，也即会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况。
因此，可以采用方式二，按照先频域后时域的顺序进行REG bundle到REG的映射，以确保REG bundle中不同REG上NR PDCCH DMRS对应RE数量相同，进而确保良好的信道估计效果。
图8是根据本公开的实施例示出的另一种REG bundle到REG的映射示意图。
在一个实施例中，在所述CORESET中部分时域符号上分布有LTE CRS时，例如以图3所示实施例为例，CORESET的前2个符号上分布有LTE CRS，CORESET的第3个符号上未分布有LTE CRS，那么可以按照先频域后时域的顺序进行REG bundle到REG的映射。
如图8所示，例如REG bundle的大小为3，也即一个REG bundle映射3个REG，CORESET在频域上对应3个RB。
按照先频域后时域的顺序进行REG bundle到REG的映射，可以从RB#n的第一个符号上开始，沿着频域将REG bundle映射到REG，那么REG bundle#n可以映射到RB#n第一个符号对应的REG、RB#n+1第一个符号对应的REG和RB#n+2第一个符号对应的REG；
以此类推，REG bundle#n+1可以映射到RB#n第二个符号对应的REG、RB#n+1第二个符号对应的REG和RB#n+2第二个符号对应的REG，REG bundle#n+2可以映射到RB#n第三个符号对应的REG、RB#n+1第三个符号对应的REG和RB#n+2第三个符号对应的REG。其中REG bundle#n+1和REG bundle#n+2并未在图8中标出。
可见，在CORESET中部分时域符号上分布有LTE CRS时，按照先频域后时 域的顺序进行REG bundle到REG的映射，例如图8所示，一个REG bundle包含3个REG，REG bundle中每个REG上NR PDCCH DMRS对应RE数量相同，从而可以确保良好的信道估计效果。
图9是根据本公开的实施例示出的又一种资源元素群组捆确定方法的示意流程图。如图9所示，所述根据控制资源集CORESET中长期演进小区专属参考信号LTE CRS的分布情况，确定资源元素群组捆REG bundle到REG的映射方式包括：
在步骤S901中，在所述CORESET中部分时域符号上分布有LTE CRS时，确定分布有LTE CRS的第一部分时域符号，以及未分布有LTE CRS的第二部分时域符号；
在步骤S902中，确定所述第一部分时域符号在所述CORESET中对应的第一子CORESET，以及所述第二部分时域符号在所述CORESET中对应的第二子CORESET；
在步骤S903中，在所述第一子CORESET中确定所述映射方式包括所述第一方式，在所述第二子CORESET中确定所述映射方式包括所述第一方式。
在一个实施例中，在所述CORESET中部分时域符号上分布有LTE CRS时，另一部分时域符号上未分布有LTE CRS，那么在分布有LTE CRS的时域符号对应的REG上，减少了用于传输NR PDCCH DMRS的RE对应RE数量，而在未分布有LTE CRS的时域符号对应的REG上，并未减少用于传输NR PDCCH DMRS的RE对应RE数量，从而REG bundle中在分布有LTE CRS的时域符号对应的REG上和未分布有LTE CRS的时域符号对应的REG上，NR PDCCH DMRS对应RE数量不同，也即会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况。
在这种情况下，除了可以采用方式二进行映射，还可以通过方式一进行映射，但是在映射前需要先对CORESET进行一些操作。
在一个实施例中，可以先在所述CORESET中部分时域符号上分布有LTE CRS时，确定分布有LTE CRS的第一部分时域符号，以及未分布有LTE CRS的第二部分时域符号。
然后确定所述第一部分时域符号在所述CORESET中对应的第一子CORESET，以及所述第二部分时域符号在所述CORESET中对应的第二子CORESET。相当于将分布有LTE CRS的时域符号在原CORESET对应的资源划分为一个子CORESET，未分 布有LTE CRS的时域符号在原CORESET对应的资源划分为另一个子CORESET。
最后在所述第一子CORESET中确定所述映射方式包括所述第一方式，在所述第二子CORESET中确定所述映射方式包括所述第一方式。
对于第一子CORESET，由于第一子CORESET中全部时域符号上均分布有LTE CRS时，那么每个REG上都存在LTE CRS，而每个REG上与LTE CRS存在冲突的NR PDCCH DMRS对应的RE对应RE数量是相同的，相当于在每个REG上都减少了相同数量的用于传输NR PDCCH DMRS的RE，所以REG bundle中不同REG上NR PDCCH DMRS对应RE数量仍然是相同的，那么在第一子CORESET内，不会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况。
对于第二子CORESET，由于第二子CORESET中全部时域符号上均未分布有LTE CRS时，那么每个REG上都不存在LTE CRS，而每个REG上原本NR PDCCH DMRS对应的RE对应RE数量就是相同的，所以REG bundle中不同REG上NR PDCCH DMRS对应RE数量也就是相同的，那么在第二子CORESET内，不会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况。
因此，针对第一子CORESET，可以沿用第一方式，按照先时域后频域的顺序进行REG bundle到REG的映射；针对第二子CORESET，也可以沿用第一方式，按照先时域后频域的顺序进行REG bundle到REG的映射。在确保REG bundle中不同REG上NR PDCCH DMRS对应RE数量相同的基础上，可以减少对现有协议的调整。
图10是根据本公开的实施例示出的又一种REG bundle到REG的映射示意图。
在一个实施例中，在所述CORESET中第一部分时域符号上分布有LTE CRS时，第二部分时域符号上未分布有LTE CRS，例如以图3所示实施例为例，CORESET的前2个符号上分布有LTE CRS，CORESET的第3个符号上未分布有LTE CRS，那么如图10所示，可以将前2个符号在所述CORESET对应的资源划分为第一子CORESET，将第3个符号在所述CORESET对应的资源划分为第二子CORESET。
进而可以在所述第一子CORESET中确定所述映射方式包括所述第一方式，在所述第二子CORESET中确定所述映射方式包括所述第一方式。
需要说明的是，由于REG bundle的大小与CORESET是存在对应关系的，例如具体与CORESET duration存在对应关系，因此，将原CORESET划分为第一子CORESET和第二子CORESET后，第一子CORESET对应的REG bundle的大小与第 二子CORESET对应的REG bundle的大小可以是不同的，当然也可以是相同的。
例如在图10所示实施例中，第一子CORESET的CORESET duration为2个符号，那么对应的REG bundle大小可以为2，也即一个REG bundle映射到2个REG；第二子CORESET的CORESET duration为1个符号，那么对应的REG bundle大小可以为3，也即一个REG bundle映射到3个REG。
因此，在第一CORESET中，按照第一方式，按照先时域后频域的顺序进行REG bundle到REG的映射，可以先将REG bundle映射到第一子CORESET在RB#n中第一符号对应的REG上，然后映射到第一子CORESET的第二符号对应的REG上。由于在第一CORESET中REG bundle大小为2，在第一子CORESET的RB#n中可以映射一个REG bundle#n(包含2个REG)。以此类推，在第一子CORESET的RB#n+1中可以映射一个REG bundle#n+1，在第一子CORESET的RB#n+2中可以映射一个REG bundle#n+2。
在第二CORESET中，按照第一方式，按照先时域后频域的顺序进行REG bundle到REG的映射，可以先将REG bundle映射到第二子CORESET在RB#n中第一符号对应的REG上，然后映射到第一子CORESET的第二符号对应的REG上。由于第二子CORESET中仅存在一个符号，而且在第一CORESET中REG bundle大小为3，所以在第一子CORESET的RB#n、RB#n+1、RB#n+2的第一符号上可以映射一个REG bundle#m(包含3个REG)。
可见，在CORESET中部分时域符号上分布有LTE CRS时，通过对原CORESET进行划分，在第一子CORESET中和第二子CORESET中，分别按照先时域后频域的顺序进行REG bundle到REG的映射，例如图10所示，在第一子CORESET内的REG bundle中每个REG上NR PDCCH DMRS对应RE数量相同，在第二子CORESET内的REG bundle中每个REG上NR PDCCH DMRS对应RE数量也相同，从而可以确保良好的信道估计效果。
在一个实施例中，所述根据所述映射方式在所述CORESET中的REG上确定REG bundle包括：
根据所述第一方式在所述第一子CORESET中的REG上确定第一REG bundle；
根据所述第一方式在所述第二子CORESET中的REG上确定第二REG bundle。
由于原CORESET划分为第一子CORESET和第二子CORESET，相当于形成 了两个CORESET，所以对于终端而言，需要在两个子CORESET中分别确定REG bundle。具体可以根据所述第一方式在所述第一子CORESET中的REG上确定第一REG bundle；根据所述第一方式在所述第二子CORESET中的REG上确定第二REG bundle。
需要说明的是，对于原CORESET的划分方式和划分后每个子CORESET对应REG bundle的大小，对于终端和网络侧设备而言，可以基于协议预先确定，也可以是网络侧根据需要确定的，然后指示给终端的，例如通过系统信息、寻呼信令指示给终端。
图11是根据本公开的实施例示出的一种资源元素群组捆映射方法的示意流程图。本实施例所示的资源元素群组捆映射方法可以由网络侧设备执行，所述网络侧设备包括但不限于4G基站、5G基站、6G基站等通信系统中的基站。所述基站可以与作为用户设备的终端进行通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置。
如图11所示，所述资源元素群组捆映射方法可以包括以下步骤：
在步骤S1101中，根据控制资源集CORESET中长期演进小区专属参考信号LTE CRS的分布情况，确定资源元素群组捆REG bundle到REG的映射方式；
在步骤S1102中，根据所述映射方式在所述CORESET中映射REG bundle。
在一个实施例中，所述映射方式包括以下至少之一：
方式一：按照先时域后频域的顺序进行REG bundle到REG的映射；
方式二：按照先频域后时域的顺序进行REG bundle到REG的映射。
在一个实施例中，所述LTE CRS的分布情况包括以下至少之一：
在所述CORESET中全部时域符号上均分布有LTE CRS；
在所述CORESET中全部时域符号上均未分布LTE CRS；
在所述CORESET中部分时域符号上分布有LTE CRS(另一部分时域符号上未分布有LTE CRS)。
在一个实施例中，基于LTE CRS的分布情况，可以确定沿用已有的映射方式(例如方式一)进行REG bundle到REG的映射是否会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况，如果不会出现这种情况，那么可以基 于沿用方式一，如果会出现这种情况，可以改为按照方式二进行映射。
而LTE CRS的分布情况与是否会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况之间的关系可以是预先确定的。例如，在所述CORESET中全部时域符号上均分布有LTE CRS时，或者在所述CORESET中全部时域符号上均未分布LTE CRS时，不会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况(也即REG bundle中不同REG上NR PDCCH DMRS对应RE数量相同)；在所述CORESET中部分时域符号上分布有LTE CRS时，则会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况。
所以网络侧设备针对会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况时，对应CORESET中LTE CRS的分布情况，确定按照方式二进行映射；针对不会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况时，对应CORESET中LTE CRS的分布情况，确定按照方式一进行映射
因此，根据本公开的实施例，网络侧设备可以根据CORESET中LTE CRS(具体可以是对应RE)的分布情况，确定REG bundle到REG的映射方式，有利于避免REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况。进而根据所述映射方式在所述CORESET中映射REG bundle，根据REG bundle进行信道估计，就可以在REG bundle中每个REG上NR PDCCH DMRS对应RE数量相同的情况下进行信道估计，有利于确保信道估计的准确性。
以上实施例主要描述了有关LTE CRS与NR PDCCH DMRS冲突的情况，LTE CRS与NR PDCCH也会产生冲突。在LTE CRS与NR PDCCH冲突的情况下，可以根据LTE CRS对应RE对NR PDCCH进行打孔，或者根据LTE CRS对应RE对NR PDCCH进行速率匹配。
图12是根据本公开的实施例示出的另一种资源元素群组捆映射方法的示意流程图。如图12所示，所述根据控制资源集CORESET中长期演进小区专属参考信号LTE CRS的分布情况，确定资源元素群组捆REG bundle到REG的映射方式包括：
在步骤S1201中，在所述CORESET中全部时域符号上均分布有LTE CRS时，确定所述映射方式包括所述方式一。
在一个实施例中，在所述CORESET中全部时域符号上均分布有LTE CRS时，那么每个REG上都存在LTE CRS，而每个REG上与LTE CRS存在冲突的NR PDCCH  DMRS对应的RE对应RE数量是相同的，相当于在每个REG上都减少了相同数量的用于传输NR PDCCH DMRS的RE，所以REG bundle中不同REG上NR PDCCH DMRS对应RE数量仍然是相同的，也即不会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况。
因此，可以沿用相关技术中的映射方式，也即方式一，按照先时域后频域的顺序进行REG bundle到REG的映射，在确保REG bundle中不同REG上NR PDCCH DMRS对应RE数量相同的基础上，可以减少对现有协议的调整。
图13是根据本公开的实施例示出的又一种资源元素群组捆映射方法的示意流程图。如图13所示，所述根据控制资源集CORESET中长期演进小区专属参考信号LTE CRS的分布情况，确定资源元素群组捆REG bundle到REG的映射方式包括：
在步骤S1301中，在所述CORESET中全部时域符号上均未分布LTE CRS时，确定所述映射方式包括所述方式一。
在一个实施例中，在所述CORESET中全部时域符号上均未分布有LTE CRS时，那么每个REG上都不存在LTE CRS，而每个REG上原本NR PDCCH DMRS对应的RE对应RE数量就是相同的，所以REG bundle中不同REG上NR PDCCH DMRS对应RE数量也就是相同的，那么不会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况。
因此，可以沿用相关技术中的映射方式，也即方式一，按照先时域后频域的顺序进行REG bundle到REG的映射，在确保REG bundle中不同REG上NR PDCCH DMRS对应RE数量相同的基础上，可以减少对现有协议的调整。
图14是根据本公开的实施例示出的又一种资源元素群组捆映射方法的示意流程图。如图14所示，所述根据控制资源集CORESET中长期演进小区专属参考信号LTE CRS的分布情况，确定资源元素群组捆REG bundle到REG的映射方式包括：
在步骤S1401中，在所述CORESET中部分时域符号上分布有LTE CRS时，确定所述映射方式包括所述方式二。
在一个实施例中，在所述CORESET中部分时域符号上分布有LTE CRS时，另一部分时域符号上未分布有LTE CRS，那么在分布有LTE CRS的时域符号对应的REG上，减少了用于传输NR PDCCH DMRS的RE对应RE数量，而在未分布有LTE CRS的时域符号对应的REG上，并未减少用于传输NR PDCCH DMRS的RE对应RE 数量，从而REG bundle中在分布有LTE CRS的时域符号对应的REG上和未分布有LTE CRS的时域符号对应的REG上，NR PDCCH DMRS对应RE数量不同，也即会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况。
因此，可以采用方式二，按照先频域后时域的顺序进行REG bundle到REG的映射，以确保REG bundle中不同REG上NR PDCCH DMRS对应RE数量相同，进而确保良好的信道估计效果。
图15是根据本公开的实施例示出的又一种资源元素群组捆映射方法的示意流程图。如图15所示，所述根据控制资源集CORESET中长期演进小区专属参考信号LTE CRS的分布情况，确定资源元素群组捆REG bundle到REG的映射方式包括：
在步骤S1501中，在所述CORESET中部分时域符号上分布有LTE CRS时，确定分布有LTE CRS的第一部分时域符号，以及未分布有LTE CRS的第二部分时域符号；
在步骤S1502中，确定所述第一部分时域符号在所述CORESET中对应的第一子CORESET，以及所述第二部分时域符号在所述CORESET中对应的第二子CORESET；
在步骤S1503中，在所述第一子CORESET中确定所述映射方式包括所述第一方式，在所述第二子CORESET中确定所述映射方式包括所述第一方式。
在一个实施例中，在所述CORESET中部分时域符号上分布有LTE CRS时，另一部分时域符号上未分布有LTE CRS，那么在分布有LTE CRS的时域符号对应的REG上，减少了用于传输NR PDCCH DMRS的RE对应RE数量，而在未分布有LTE CRS的时域符号对应的REG上，并未减少用于传输NR PDCCH DMRS的RE对应RE数量，从而REG bundle中在分布有LTE CRS的时域符号对应的REG上和未分布有LTE CRS的时域符号对应的REG上，NR PDCCH DMRS对应RE数量不同，也即会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况。
在这种情况下，除了可以采用方式二进行映射，还可以通过方式一进行映射，但是在映射前需要先对CORESET进行一些操作。
在一个实施例中，可以先在所述CORESET中部分时域符号上分布有LTE CRS时，确定分布有LTE CRS的第一部分时域符号，以及未分布有LTE CRS的第二部分时域符号。
然后确定所述第一部分时域符号在所述CORESET中对应的第一子CORESET，以及所述第二部分时域符号在所述CORESET中对应的第二子CORESET。相当于将分布有LTE CRS的时域符号在原CORESET对应的资源划分为一个子CORESET，未分布有LTE CRS的时域符号在原CORESET对应的资源划分为另一个子CORESET。
最后在所述第一子CORESET中确定所述映射方式包括所述第一方式，在所述第二子CORESET中确定所述映射方式包括所述第一方式。
对于第一子CORESET，由于第一子CORESET中全部时域符号上均分布有LTE CRS时，那么每个REG上都存在LTE CRS，而每个REG上与LTE CRS存在冲突的NR PDCCH DMRS对应的RE对应RE数量是相同的，相当于在每个REG上都减少了相同数量的用于传输NR PDCCH DMRS的RE，所以REG bundle中不同REG上NR PDCCH DMRS对应RE数量仍然是相同的，那么在第一子CORESET内，不会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况。
对于第二子CORESET，由于第二子CORESET中全部时域符号上均未分布有LTE CRS时，那么每个REG上都不存在LTE CRS，而每个REG上原本NR PDCCH DMRS对应的RE对应RE数量就是相同的，所以REG bundle中不同REG上NR PDCCH DMRS对应RE数量也就是相同的，那么在第二子CORESET内，不会出现REG bundle中不同REG上NR PDCCH DMRS对应RE数量不同的情况。
因此，针对第一子CORESET，可以沿用第一方式，按照先时域后频域的顺序进行REG bundle到REG的映射；针对第二子CORESET，也可以沿用第一方式，按照先时域后频域的顺序进行REG bundle到REG的映射。在确保REG bundle中不同REG上NR PDCCH DMRS对应RE数量相同的基础上，可以减少对现有协议的调整。
在一个实施例中，所述根据所述映射方式在所述CORESET中的REG上确定REG bundle包括：
根据所述第一方式在所述第一子CORESET中的REG上映射第一REG bundle；
根据所述第一方式在所述第二子CORESET中的REG上映射第二REG bundle。
由于原CORESET划分为第一子CORESET和第二子CORESET，相当于形成了两个CORESET，所以对于终端而言，需要在两个子CORESET中分别确定REG bundle。具体可以根据所述第一方式在所述第一子CORESET中的REG上确定第一REG bundle；根据所述第一方式在所述第二子CORESET中的REG上确定第二REG  bundle。
需要说明的是，对于原CORESET的划分方式和划分后每个子CORESET对应REG bundle的大小，对于终端和网络侧设备而言，可以基于协议预先确定，也可以是网络侧根据需要确定的，然后指示给终端的，例如通过系统信息、寻呼信令指示给终端。
