Description

一种上行共享信道资源配置方法及设备
本申请要求于2019年02月14日提交中国国家知识产权局、申请号为201910114852.6、发明名称为“一种上行共享信道资源配置方法及设备”的中国专利申请的优先权，该在先申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，尤其涉及一种上行共享信道资源配置方法及设备。
背景技术
在现有4G和5G定义的基于竞争方式的随机接入过程，终端和基站之间至少需要进行四次信令的交互，称之为4-step RACH。包括以下四次传输：第一次终端向基站发送Msg1，Msg1为终端按照标准38.321或36.321中设定规则选择前导序列，用于基站进行TA估计等；第二次基站向终端发送Msg2，Msg2为Msg1的随机接入响应，其中包含了前导序列标识、TA、终端向基站发送Msg3的上行授权、TC-RNTI等；第三次终端向基站发送Msg3，当终端在Msg2中读取到Msg1对应的前导序列标识时，在发送Msg3，Msg3的内容与触发随机接入过程的事件相关；第四次基站向终端发送Msg4，Msg4为解决竞争冲突的响应，当终端检测到的Msg4中包含对应Msg3中相关的标识信息时，则视为随机接入成功。随着技术的进一步研究，目前为了降低信令开销和随机接入时延，考虑简化基于竞争方式的随机过程，增加一种新的随机接入过程，终端和基站之间至少两次信令的交互即可，称之为2-step RACH。包括一下两次传输：第一次终端向基站发送MsgA，承担4-step RACH中Msg1和Msg3的功能，为前导+PUSCH的传输结构，主要作用在于利用前导和DMRS进行信道和TA估计，不同RACH触发事件下MsgA对应的MAC PDU包含不同的内容，其中MsgA对应的PUSCH资源由基站进行免调度配置，前导序列和所述PUSCH直接存在一定的映射关系，降低资源选择冲突；第二次基站 向终端发送MsgB，承担4-step RACH中Msg2和Msg4的功能，主要用于指示随机接入的TA、C-RNTI分配、上行数据传输的授权以及竞争冲突解决等。由于触发RACH的事件不同，一般对于2-step RACH中MsgA对应PUSCH传输内容的大小也不同，由此MsgA对应的PUSCH所需的物理资源数不同，并且基站在配置所述PUSCH免调度资源时，需考虑不同RACH触发事件下MsgA中对应PUSCH的资源需求。针对2-step RACH，需要设计MsgA对应的PUSCH免调度资源配置解决方案，以满足不同MsgA的传输资源数需求。目前标准技术方案中还未形成对MsgA对应的PUSCH免调度资源配置的解决方案。
因此，本发明提出一种上行共享信道资源配置方法及设备，解决了基站免调度方式下传输MsgA对应的PUSCH物理资源配置问题，通过资源配置的方法满足不同RACH触发事件下MsgA中对应PUSCH的资源需求。

为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
以下结合附图，详细说明本申请各实施例提供的技术方案。
图1为本申请实施例提供的一种上行共享信道资源配置方法的流程图，本实施例提供的一种上行共享信道资源配置方法包括以下步骤：
步骤101：接收资源配置信息。
在步骤101中，接收资源配置信息，所述资源配置信息包括前导序列配置信息和PUSCH配置信息。
在本实施例中，所述资源配置信息的发送设备例如可以是基站。其中的前导序列配置信息、PUSCH配置信息由所述基站配置。所述接收资源配置信息的设备例如可以是终端，所述终端内设置有前导序列与PUSCH配置信息的对应关系，每个前导序列至少有一种与其对应的PUSCH配置信息。当一个前导序列映射到多种PUSCH配置信息时，在所述PUSCH配置信息中按照系统设定的规则选择其中一种PUSCH配置信息。所述PUSCH配置信息包括时域资源配置信息、频域资源配置信息、DMRS配置信息、MCS配置信息、跳频配置信息中至少一种。
作为本申请的另一种实施方式，所述资源配置信息还包括前导序列与PUSCH配置信息的对应关系，所述对应关系可以通过所述基站设置，使每个前导序列至少有一种与其对应的PUSCH配置信息。所述终端通过接收所述资源配置信息获取所述对应关系。
步骤102：发送前导序列和PUSCH承载信息。
在步骤102中，在所述前导序列配置信息和PUSCH配置信息范围内，根据PUSCH承载信息量选定至少一组前导序列和PUSCH资源。发送前导序列和PUSCH承载信息。
在本实施例中，所述一组前导序列和PUSCH资源为一个前导序列和与所述前导序列对应的一种PUSCH资源配置。所述前导序列和PUSCH承载信息的发送设备在接收所述资源配置信息后，根据所述PUSCH承载信息量选择所述PUSCH配置信息中的可以满足信息需求的PUSCH资源配置集合，即PUSCH资源配置量不低于PUSCH承载信息量，再根据所述PUSCH配置与所述前导序列的对应关系选择前导序列集合。进一步地在前导序列集合中选择一个前导序列，根据前导序列和PUSCH配置信息的对应关系选择一种PUSCH资源，发送选择的前导序列和PUSCH承载信息。其中选择前导序列和PUSCH资源配置的先后顺序可以在实现过程中可以进行调整，例如设置了前导序列与PUSCH承载信息量范围的对应关系或者PUSCH资源配置量为一种，可以根据PUSCH承载信息量先选择前导序列，再根据前导序列与PUSCH配置信息对应关系选择一种资源配置。
进一步的，所述前导序列和PUSCH承载信息的发送设备例如可以是包括第一配置单元和发送单元的终端。当接收到所述资源配置信息后，由所述第一配置单元根据所述PUSCH承载信息量选择所述资源配置信息中的前导序列配置和PUSCH资源，根据所述PUSCH配置信息与所述前导序列的对应关系选择所述前导序列，根据所述前导序列选择前导序列配置信息。最后将所述前导序列和所述PUSCH承载信息发送至所述发送单元，由所述发送单元发出。
在本实施例提供的上行共享信道资源配置方法的两个步骤中，所述PUSCH配置信息中包括一种或多种PUSCH资源配置。所述PUSCH资源的配置量可以根据PUSCH配置信息的时域资源配置信息、频域资源配置信息、 DMRS配置信息、MCS配置信息、跳频配置信息等计算传输包大小而得出。所述PUSCH承载信息量根据RACH触发事件的需要传输的MAC PDU大小得出。
进一步的，将所述前导序列分组，使每组前导序列对应一种PUSCH承载信息量的范围。根据所述PUSCH承载信息选择的PUSCH资源的配置量包括一种或多种的情况。根据PUSCH配置信息选择PUSCH资源，所述PUSCH资源的配置量为一种，不小于所述PUSCH承载信息量的最大值；或所述PUSCH资源的配置量多于一种，每种所述PUSCH资源的配置量不小于对应的PUSCH承载信息量范围上限。
例如，所述PUSCH配置信息2stepRACH-PUSCH-Config包含多个ResourceConfig_n(n＝1,2,…)，每种ResourceConfig_n(n＝1,2,…)对应一种PUSCH资源的配置量。在所述PUSCH资源的配置量为一种时，所述PUSCH资源的配置量不小于所述PUSCH承载信息量的最大值。所述PUSCH资源的配置量大于一种时，每组前导序列对应一种PUSCH承载信息量的范围。因一个前导序列可以对应一种PUSCH资源的配置量，同时每组前导序列中的一个前导序列对应一种PUSCH承载信息量范围。进一步地，使每种PUSCH资源的配置量对应一种PUSCH承载信息量范围。每种所述PUSCH资源的配置量不小于对应的PUSCH承载信息量范围上限，多种PUSCH承载信息量范围也可以对应相同的PUSCH资源的配置量。
例如，将所述前导序列分为N组，第n(n＝1,2,…,N)组前导序列对应的PUSCH承载信息量范围为[requiredTBsizemin_n,requiredTBsizemax_n],当所述PUSCH承载信息对应的PUSCH承载信息量范围在[requiredTBsizemin_n,requiredTBsizemax_n]之内时，则可以对应选择第n组的前导序列。其中所述前导序列对应PUSCH承载信息量范围包含该范围上下限相同的特殊情况，例如第n组前导序列对应的PUSCH承载信息量范围的上下限相同，即 requiredTBsizemin_n＝requiredTBsizemax_n。此时所述前导序列的分组n(n＝1,2,…,N)与PUSCH承载信息量范围[requiredTBsizemin_n,requiredTBsizemax_n]对应，一个前导序列的分组n(n＝1,2,…,N)对应到一个PUSCH承载信息量。再根据所述前导序列与所述PUSCH资源的配置量范围的对应关系，即前导分组n(n＝1,2,…,N)中的一个或多个前导序列对应一种或多种PUSCH配置信息，获取PUSCH资源的配置量，所述PUSCH资源的配置量的大小不低于所述前导序列对应的PUSCH承载信息量范围上限。
所述PUSCH承载信息量范围可以为配置的范围值，还可以等同于所述前导序列对应的PUSCH资源的配置量范围。
在本申请的实施例中，例如将前导序列分为A和B两组，其中B组对应的PUSCH承载信息量超过一个配置值ra-MsgASizeGroupA，A组对应的PUSCH承载信息量范围为未超过ra-MsgASizeGroupA，B组对应的PUSCH承载信息量范围为超过ra-MsgASizeGroupA，则当UE发起随机接入时，如果需求的PUSCH承载信息量超过ra-MsgASizeGroupA，则选择B组对应的前导序列，否则选择A组对应的前导序列。
由于一个前导序列对应了一种PUSCH资源配置，进一步对应所述PUSCH资源的配置量，相应的一组前导序列对应的PUSCH资源承载信息量范围可以对应为该组前导序列对应的PUSCH资源配置量范围。假设A组中前导序列对应的PUSCH资源的配置量范围为范围1，B组前导序列对应的PUSCH资源的配置量范围为范围2。当UE发起随机接入时，如果需求的PUSCH承载信息量在范围1中，则选择A组中前导序列对应的PUSCH资源的配置量。如果如果需求的PUSCH承载信息量在范围2中，则选择B组中前导序列对应的PUSCH资源的配置量。

在步骤202中，在所述前导序列配置信息和PUSCH配置信息范围内，根据PUSCH承载信息量选定至少一组前导序列和PUSCH资源。发送前导序列和PUSCH承载信息。
步骤203：对所述前导序列和PUSCH承载信息进行检测。
在步骤203中，对所述前导序列和PUSCH承载信息进行检测。所述前导序列和PUSCH承载信息的接收设备例如可以是包括第二配置单元和接收检测单元的基站。
所述基站在接收到所述前导序列和PUSCH承载信息后，通过所述第二配置单元向所述接收检测单元配置基站发送检测所需要的资源配置信息，包括所述前导序列配置信息、PUSCH配置信息。进一步的，还包括前导序列与所述PUSCH配置信息的对应关系。所述接收检测单元首先根据所述前导序列配置信息对所述前导序列进行检测，再根据所述前导序列与所述PUSCH配置信息的对应关系确定PUSCH资源，包括所述PUSCH的资源位置、DMRS配置、MCS配置等。最后根据所述PUSCH资源对所述PUSCH承载信息进行检测，将检测出的传输包递交给MAC层。
图3为另一种包括检测步骤的上行共享信道资源配置方法流程图，本实施例提供的上行共享信道资源配置方法包括以下步骤：
步骤301：发送资源配置信息。
在步骤301中，发送资源配置信息，所述资源配置信息包括前导序列配置信息和PUSCH配置信息。
在本实施例中，所述资源配置信息的发送设备例如可以是基站。其中的前 导序列配置信息、PUSCH配置信息由所述基站配置。所述接收资源配置信息的设备例如可以是终端，所述终端内设置有前导序列与PUSCH配置信息的对应关系，每个前导序列至少有一种与其对应的PUSCH配置信息。当一个前导序列映射到多种PUSCH配置信息时，在所述PUSCH配置信息中按照系统设定的规则选择其中一种PUSCH配置信息。所述PUSCH配置信息包括时域资源配置信息、频域资源配置信息、DMRS配置信息、MCS配置信息、跳频配置信息中至少一种。
进一步地，所述PUSCH配置信息由所述基站的资源池提供。例如可以将所述PUSCH配置信息命名为：2stepRACH-PUSCH-Config，其可设置为2stepRACH-PUSCH-Config：{ResourceConfig1，ResourceConfig2，…}，其中ResourceConfig_n(n＝1，2，…)对应一种PUSCH配置资源，每种PUSCH资源信息可包括且不限于如PUSCH配置信息表所示的时域资源配置信息、频域资源配置信息、DMRS配置信息、MCS配置信息、跳频配置信息。
进一步地，如果所述基站和/或所述资源配置信息的接收设备已经设定了所述PUSCH配置信息中的部分配置信息，则所述设定后的配置信息无需在PUSCH配置信息中体现，或者如PUSCH配置信息表所示将配置信息设置为可选项。例如资源池中的MCS固定为一种调制方式，则可以删除PUSCH配置信息表中的mcsAndTBS配置项，或将该项设置为可选项，即根据系统需求配置该配置项。

在本实施例中，所述PUSCH配置信息除上述PUSCH配置信息表的表达方式之外还可以采用其他等效的表述方式，即达到配置发送所述前导序列和PUSCH承载信息对应的时域资源配置信息、频域资源配置信息、DMRS配置信息、MCS配置信息、跳频配置信息等的目的。当两种PUSCH资源所包含的其中一种配置信息不同时，视为两种配置。以PUSCH配置信息表中给出的ResourceConfig_n(n＝1,2,…)为例，假设ResourceConfig_1和ResourceConfig_2的DMRS端口配置不同而其他配置信息均相同，则ResourceConfig_1和ResourceConfig_2为两种PUSCH资源。
