具体实施方式
图1是本发明的一个实施例的上行时频资源集合的配置方法的流程图。
在S11中，对已配置上行传输复用模式的用户配置至少一个所述上行时频资源集合，所述上行时频资源集合包括时频资源单元，所述时频资源单元为所述用户在其上进行速率匹配的时频资源。
在S12中，向所述用户发送至少一个指示组，以指示至少一个所述上行时频资源集合。
其中，一个所述上行时频资源集合由至少一个指示组指示，所述指示组包括符号级指示，资源块级指示和子载波级指示；所述上行传输复用模式指所述用户可以与其它一个或多个用户复用相同的时频资源进行上行传输。
通过上述方法，可以避免eMBB用户在上行数据传输时所占用的时频资源与URLLC的上行DMRS的时频资源位置发生冲突，从而保证URLLC用户的可靠性。
在一些实施例中，基站在对所述用户配置至少一个所述上行时频资源集合的同时，对所述上行时频资源集合配置至少一个参考范围，其中，一个上行时频资源集合对应一个参考范围。这里的“同时”并非指基站配置上行时频资源集合和配置参考范围在时刻上要完全相同。
在具体实施中，所述参考范围可以由基站通过RRC信令对所述用户进行配置，或采用默认设置的方式对所述用户进行配置。并且，基站为用户配置所述参考范围与指示组的对应关系，用户在收到指示组后可根据已配置的对应关系，在对应的所述参考范围内根据指示组指示确定所述上行时频资源集合。
在具体实施中，一个eMBB用户可以被配置一个或多个所述参考范围；一个所述参考范围内可以配置有一个或多个所述上行时频资源集合；一个所述时频资源集合可以由一个或多个指示组指示。
具体地，参考图2、图3和图4，图2、图3均为本发明的一个实施例的速率匹配时频资源分布示意图；图4是本发明的一个实施例的上行解调参考信号的端口图样示意图。
在第一实施例中，eMBB用户的工作子载波间隔为15kHz，基站为所述eMBB用户配置为上行传输复用模式，并通过RRC信令对所述eMBB用户进行配置所述上行时频资源集合及参考范围，所述eMBB用户在所述上行时频资源集合包含的时频资源单元上进行速率匹配。
在具体实施中，***中有一个URLLC用户，被标识为第一URLLC用户。参见图2，所述第一URLLC用户被配置为采用免调度类型一(configured grant UL transmission type 1)进行上行传输，子载波间隔为15kHz，且传输资源周期为2符号，在每个所述周期内传输的时频资源位置如下：在频域上为PRB0-PRB2，在时域上为周期内的前两个符号，上行DMRS占一个符号，且所述第一URLLC用户被配置的上行DMRS端口号为上行DMRS配置类型2中的端口1，位于一个PRB内的子载波0，1，6和7四个子载波上。
在本实施例中，基站通过配置第一上行时频资源集合向所述eMBB用户指示第一URLLC用户的上行DMRS的时频资源位置，并同时为该用户配置第一参考范围。所述第一参考范围即为所述上行时频资源的参考范围，在频域上为PRB(physical resource block，物理 资源块)0-PRB9，其中，PRB索引可以为小区级的公共PRB索引，也可以为eMBB用户的激活带宽部分的专用PRB索引。所述参考范围在时域上为所述eMBB用户的工作子载波间隔所对应的一个时隙。所述第一上行时频资源集合由一个指示组来指示，标记为第一指示组。
具体地，在第一指示组中，符号级指示采用第一比特位图进行指示，所述第一比特位图的大小为所述参考范围包含的总符号数，即为14比特，每一比特对应所述参考范围内在时域上的一个符号，即为eMBB用户的工作子载波间隔所对应的一个符号。如图2所示，根据第一URLLC用户上行DMRS的时域传输位置，第一比特位图可以确定为[10101010101010]，在具体实施中，第一比特位图可以从最高有效位(Most Significant Bit，MSB)到最低有效位(Least Significant Bit，LSB)指示时域符号由小到大，或者指示时域符号由大到小，因此第一比特位图也可以为[01010101010101]。
进一步，在第一指示组中，资源块级指示采用第二比特位图进行指示，所述第二比特位图的大小为所述参考范围包含的PRB数，即为10比特，每一比特对应所述参考范围内在频域上的一个PRB。如图2所示，根据第一URLLC用户上行DMRS的频域传输位置，第二比特位图可以确定为[1110000000]，同样地，第二比特位图也可以为[0000000111]。
进一步，在第一指示组中，子载波级指示采用第三比特位图进行指示，所述第三比特位图的大小为一个PRB内包含的子载波数，即为12比特，每一比特对应所述参考范围内在一个PRB内的一个子载波。参考图4，根据第一URLLC用户上行DMRS端口图样，且由于所述第一URLLC用户被配置的上行DMRS端口号为上行DMRS配置类型2中的端口1，第三比特位图可以确定为[110000110000]。
在本实施例中，子载波级指示还可以采用指示上行DMRS配置类型和上行DMRS端口号的及DMRS对应的子载波间隔的方式进 行指示，表示在所述解调参考信号发送端口对应的子载波索引上进行速率匹配，且所述子载波索引由所述用户根据配置的解调参考信号配置类型，解调参考信号端口号及所述解调参考信号对应子载波间隔与所述用户对应的子载波间隔计算确定，具体方式为：用高一位比特来指示上行DMRS配置类型，高一位比特为0表示上行DMRS配置类型1；高一位比特为1表示上行DMRS配置类型2。并用X个比特来指示上行DMRS端口号，在本实施例中，占用一个符号的上行DMRS配置类型2的总端口数为6，即X为6，用中间六位比特指示。并用低两位比特来指示DMRS对应的子载波间隔与eMBB用户子载波间隔的关系，00表示子载波间隔相同，01表示DMRS对应的子载波间隔为eMBB用户子载波间隔的2倍，10表示4倍，11表示8倍。综上，上行DMRS端口号为上行DMRS配置类型2的端口1可以由9比特来表示，即为[101000000]。eMBB用户根据收到的子载波级指示，由高一比特确定为DMRS配置类型2，因此确定端口图样如图4所示，继续根据中间六比特取值010000可以确定DMRS端口号为1，对应DMRS子载波间隔下的子载波索引为0，1，6和7，继续根据低两比特取值00可以确定为DMRS对应的子载波间隔与eMBB用户的子载波间隔相同，因此，eMBB用户可以确定子载波级指示为eMBB用户子载波间隔下一个物理资源块的子载波索引0，1，6和7。
在具体实施中，基站将第一指示组通过RRC信令发送给eMBB用户，用户根据第一指示组可以确定在每个时隙内的符号0，2，4，6，8，10和12，频域PRB0-PRB3上，且在每个PRB内的子载波0，1，6和7上进行速率匹配，即不发送上行数据。
参考图3，***中有另一个URLLC用户，被标识为第二URLLC用户。所述第二URLLC用户被配置为采用免调度类型一进行上行传输，子载波间隔为30kHz，且传输资源周期为7符号，在每个周期内传输的时域资源位置为周期内的前7个符号，每个周期内传输的频域资源位置为两个PRB。因eMBB用户的子载波间隔为15kHz，因此第二URLLC用户的一个符号长度是eMBB用户一个符号长度的一 半，一个PRB的大小是eMBB用户中一个PRB大小的二倍。
在本实施例中，基站通过第二上行时频资源集合向eMBB用户指示第二URLLC用户的上行DMRS的时频资源位置，并同时为所述eMBB用户配置第一参考范围。所述第二上行时频资源集合由一个指示组来指示，标记为第二指示组。
在本实施例中，第二URLLC用户的第一个PRB在所述第一时频参考范围内的对应频域位置PRB3-PRB4，第二个PRB的对应频域位置为PRB5-PRB6。
在本实施例中，第二URLLC用户上行DMRS配置为一个符号，且被配置的上行DMRS端口号为上行DMRS配置类型2的端口2，位于30kHz子载波间隔下的一个PRB内的子载波2，3，8和9四个子载波上。
具体地，在第二指示组中，符号级指示采用第一比特位图进行指示，共包含14比特，每一比特对应所述参考范围内在时域上的一个符号，即为eMBB用户的工作子载波间隔所对应的一个符号。因第二URLLC用户的一个传输周期为7符号，且一个时域符号的长度是eMBB用户符号长度的一半，eMBB用户的一个时隙内包含第二URLLC用户的4个传输周期，根据第二URLLC用户的上行DMRS的时域传输位置，第一比特位图可以确定为[10010001001000]。同样地，第一比特位图也可以为[00010010001001]。
进一步，在第二指示组中，资源块级指示采用第二比特位图进行指示，所述第二比特位图的大小为所述参考范围包含的PRB数，即为10比特，每一比特对应所述参考范围内在频域上的一个PRB。如图3所示，根据第二URLLC用户上行DMRS的频域传输位置，第二比特位图可以确定为[0001111000]。
进一步，在第二指示组中，子载波级指示采用第三比特位图进行指示，所述第三比特位图的大小为eMBB用户的子载波间隔下一个 PRB内包含的子载波数，即为12比特，每一比特对应所述参考范围内在一个PRB内的一个子载波。
根据第二URLLC用户的上行DMRS端口图样，其在30kHz子载波间隔下的一个PRB内的子载波索引为：2，3，8，9。考虑到30kHz子载波间隔下的一个PRB大小的为15kHz子载波间隔下的一个PRB大小的两倍，经过折算，第二URLLC用户的第一个PRB内的子载波2、子载波3、子载波8和子载波9对应到第一参考范围内的PRB3中的子载波4、子载波5、子载波6、子载波7和PRB4中的子载波4、子载波5、子载波6、子载波7。所述第二URLLC用户的第二个PRB内子载波2、子载波3、子载波8和子载波9对应到第一参考范围内的PRB5中的子载波4、子载波5、子载波6、子载波7和PRB6中的子载波4、子载波5、子载波6、子载波7。因此第三比特位图指示第一参考范围的一个PRB中的子载波4-7，可以确定为[000011110000]。
在具体实施中，基站将第二指示组通过RRC信令发送给eMBB用户，用户根据第二指示组可以确定在每个时隙内的符号0，3，7和10，频域PRB3-PRB6上，且在每个PRB内的子载波4，5，6和7上进行速率匹配，即不发送上行数据。
在一些实施例中，所述上行时频资源集合可以由基站通过RRC信令与动态指示相结合的方式对所述用户进行配置；所述用户在收到所述动态指示之前，在由RRC信令配置的速率匹配时频资源集合所包含的时频资源单元上进行速率匹配；在收到所述动态指示后，所述用户在所述动态指示所配置的上行时频资源集合所包含的时频资源单元上进行速率匹配。
具体地，结合参考图2，图3和图4，通过以下实施例说明所述上行时频资源集合可以由基站通过RRC信令与动态指示相结合的方式对所述用户进行配置。
在第二实施例中，eMBB用户的工作子载波间隔为15kHz，基站为所述eMBB用户配置为上行传输复用模式，并通过RRC信令与动 态指示相结合的方式为所述eMBB用户配置上行时频资源集合及参考范围。
在本实施例中，基站通过RRC信令与动态指示相结合的方式对所述用户配置上行时频资源集合，且所述动态指示为通过MAC控制单元(MAC Control Element，MAC CE)对用户指示至少一个上行时频资源集合。如图2、图3所示，基站通过RRC信令为eMBB用户配置两个上行时频资源集合，标记为第一上行时频资源集合和第二上行时频资源集合，并同时为所述eMBB用户配置第一参考范围。所述第一上行时频资源集合和第二上行时频资源集合分别由第一指示组和第二指示组指示，所述第一指示组和第二指示组均包括第一比特位图、第二比特位图和第三比特位图。所述第一参考范围在频域上为PRB0-PRB9，其中，PRB索引可以为小区级的公共PRB索引，也可以为eMBB用户的激活带宽部分的专用PRB索引。所述参考范围在时域上为所述eMBB用户的工作子载波间隔所对应的一个时隙。
由上述第一实施例可知，所述第一指示组的第一比特位图为[10101010101010]，第二比特位图为[1110000000]，第三比特位图为[110000110000]。所述第二指示组的第一比特位图为[10010001001000]，第二比特位图为[0001111000]，第三比特位图为[000011110000]。
同样地，在具体实施中，所述各比特位图均可以从最高有效位到最低有效位指示时域符号由小到大，或者指示时域符号由大到小，具体细节在此不再赘述。
在本实施例中，eMBB用户在未收到任何MAC CE指示之前，在由RRC信令配置的第一上行时频资源集合和第二上行时频资源集合所包含的时频资源单元上进行速率匹配。
在第一时刻，所述eMBB用户收到MAC CE指示，仅指示了第一上行时频资源集合，因此，在第一时刻之后，所述eMBB用户将在第一上行时频资源集合所包含的时频资源单元上进行速率匹配。在第 二时刻，所述eMBB用户收到一个新的MAC CE指示，仅指示了第二上行时频资源集合，因此，在第二时刻之后，所述eMBB用户将在第二上行时频资源集合所包含的时频资源单元上进行速率匹配。
在第三实施例中，eMBB用户的工作子载波间隔为15kHz，基站为所述eMBB用户配置为上行传输复用模式，并通过RRC信令与动态指示相结合的方式为所述eMBB用户配置上行时频资源集合及参考范围。
在本实施例中，基站通过RRC信令与动态指示相结合的方式对所述eMBB用户配置上行时频资源集合，且所述动态指示为通过下行控制信息(Downlink Control Information，DCI)对用户指示至少一个上行时频资源集合。如图2、图3所示，基站通过RRC信令为eMBB用户配置两个上行时频资源集合，标记为第一上行时频资源集合和第二上行时频资源集合，并同时为所述eMBB用户配置第一参考范围。所述第一上行时频资源集合和第二上行时频资源集合分别由第一指示组和第二指示组指示，所述第一指示组和第二指示组均包括第一比特位图、第二比特位图和第三比特位图。所述第一参考范围在频域上为PRB0-PRB9，其中，PRB索引可以为小区级的公共PRB索引，也可以为eMBB用户的激活带宽部分的专用PRB索引。所述参考范围在时域上为所述eMBB用户的工作子载波间隔所对应的一个时隙。

同样地，在具体实施中，所述各比特位图均可以从最高有效位到最低有效位指示时域符号由小到大，或者指示时域符号由大到小，具体细节在此不再赘述。
在本实施例中，eMBB用户在未收到任何DCI指示之前，在由 RRC信令配置的第一上行时频资源集合和第二上行时频资源集合所包含的时频资源单元上进行速率匹配。
在第一时刻，所述eMBB用户收到一个DCI指示，所述DCI指示包含两个信息比特，当所述两个比特为10时，DCI仅指示了第一上行时频资源集合，因此，在第一时刻之后，所述eMBB用户将在第一上行时频资源集合所包含的时频资源单元上进行速率匹配。在第二时刻，所述eMBB用户收到一个新的DCI指示，为01，仅指示了第二上行时频资源集合，因此，在第二时刻之后，所述eMBB用户将在第二上行时频资源集合所包含的时频资源单元上进行速率匹配。
在具体实施中，可以为发送所述上行时频资源集合的DCI指示新设计一个DCI格式或复用现有DCI格式，且对该DCI的监听周期可以由基站来配置。
