Description

一种信息调度方法及相关设备 技术领域
本发明涉及通信技术领域，尤其涉及一种信息调度方法及相关设备。
背景技术
随着物联网(Internet of Things，简称“IoT”)技术的不断发展，机器类型通信(Machine Type Communication，简称“MTC”)，也称机器间通信(Machine To Machine，简称“M2M”)，其涵盖智能抄表、医疗检测、物流检测、工业检测监控、智能社区以及可穿戴设备通信等通信领域，将成为未来通信领域的一项重要应用。对于窄带蜂窝物联网通信(Narrowband Cellular IoT，简称“NB CIoT”)系统，其采用物理下行控制信道(Physical Downlink Control Channel,简称“PDCCH”)来发送下行控制信息，下行控制信息中包含有用户设备(User Equipment，简称“用户设备”)的调度信息，在一个时间(例如一个子帧，一个帧或者一个时隙等)发送的下行控制信息中可以包括有多个用户设备的调度信息，如上行调度配置信息(UL Allocation)、下行调度配置信息(DL Allocation)、随机接入配置信息以及上行传输数据的确认ACK(或非确认NACK)反馈等等。
目前，在实际应用中，每隔一个下行控制信息发送间隔，用户设备接收一次下行控制信息，并检测该下行控制信息上是否存在自己的调度信息，从而在检测到存在自己的调度信息时按照该调度信息中指示的时间和频率去发送或接收数据。具体的，用户设备为获取自己的调度配置信息，先接收整个下行控制信息，并通过循环冗余校验(Cyclic Redundancy Check，简称“CRC”)校验确定该下行控制信息是否被正确接收。当校验成功及确定该下行控制信息被正确接收之后，则进一步通过该用户设备的无线网络临时标识符(Radio Network Temporary Identity，简称“RNTI”)匹配得到该下行控制信息中该RNTI对应的调度信息作为自己的调度信息，以基于该调度信息中指示的时间和频率发送或接收数据。
然而，一个下行控制信息往往包括很多用户设备的调度信息，这就使得该下行控制信息数据包较大。而该下行控制信息中大部分信息对单个用户设备是没有用的，每个用户设备需要的仅是该下行控制信息中的一小部分信息，接收整个下行控制信息就导致增加了用户设备的功率消耗，以及减少了用户设备的待机时间。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清 楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
应当理解的是，本发明实施例的技术方案可以应用于窄带蜂窝物联网通信(Narrowband Cellular IoT，简称“NB CIoT”)系统，或者其他物联网通信系统中。在本发明实施例中，用户设备(User Equipment，简称为“UE”)还可称之为终端(Terminal)、移动台(Mobile Station，简称为“MS”)或移动终端(Mobile Terminal)等。例如，用户设备可以是移动电话(或称为“蜂窝”电话)、具有移动终端的计算机或具有无线信号接收和发射能力的小型设备等，例如，用户设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，或者能够无线接入网络的智能水电表、家用电器、监控仪器等。在本发明实施例中，基站为该物联网通信系统如NB CIoT中的基站，下述实施例中简称为基站进行说明。
请参见图1，是本发明实施例的一种应用场景示意图。如图1所示，在物联网通信系统如NB CIoT系统中的一个基站下，即该基站的小区(Cell)内，可能包括几十个，或几百个用户设备(图1中仅示例性示出其中的3个用户设备即UE1、UE2和UE3)。该基站下的用户设备也叫接入该基站的用户设备。基站按照一定的时间间隔，向小区内的用户设备发送下行控制信息，如发送下行控制信息(Downlink Control Information，简称“DCI”)，则基站两次发送下行控制信息或者用户设备两次接收下行控制信息之间的时间间隔可称为DCI间隔(DCI Interval)。下面结合图2，以基站发送的下行控制信息为DCI为例，对下行控制信息的结构进行说明。如图2所示，DCI有固定为8bit的Len域，该Len用于指示DCI净荷Payload的长度，Len后紧接着为用于承载信息的Payload，其大小为Len中指示的长度*8bit。其中，该Payload中可包括有多个用户设备的调度信息如上行调度配置信息(UL Allocation)、下行调度配置信息(DL Allocation)、随机接入配置信息(RACH Config)以及上行传输数据的确认ACK(或非确认NACK)反馈等等，具体的，该Payload中的具体内容可以参照以下表1：
表1
Figure PCTCN2015082428-appb-000001
需要指出的是，本发明实施例的下行控制信息并不限于上述的DCI，在未来的NB CIoT系统或其他无线物联网通信系统中，该下行控制信息还可能包括其他时隙结构和物理资源单元等内容。小区内的用户设备从基站下发的下行控制信息获取得到自己的调度信息，从而基于该调度信息中指定的时间、频率资源发送或接收数据。
请参见图3，是本发明实施例提供的一种信息调度方法的流程示意图，本发明实施例的所述方法可具体应用于用户设备中，具体的，该信息调度方法可包括以下步骤：
S101：用户设备确定至少一个目标调度组的调度信息在基站发送的下行控制信息中的位置；其中，所述下行控制信息包括多个调度组的调度信息，所述多个调度组由所述基站根据所述基站下的多个用户设备的第一用户标识符对 所述多个用户设备进行分组得到，且所述至少一个目标调度组包括所述用户设备的第一用户标识符对应的第一调度组。
需要说明的是，该下行控制信息中的多个调度组包括基站根据该基站下(即该基站对应的服务小区)的所有用户设备，也即基站所服务的所有用户设备的第一用户标识符对该所有用户设备进行分组得到的调度组，每个用户设备根据自己的第一用户标识符对应该分组中的一个调度组，从而该分组得到的任一调度组包括至少一个用户设备。其中，该多个调度组中的每个调度组的调度信息可具体用于调度该调度组中的至少一个用户设备。本发明实施例以每个调度组的调度信息仅调度该调度组中的一个用户设备为例进行说明。
具体实施例中，该至少一个目标调度组包括该用户设备的第一用户标识符对应的第一调度组，即该用户设备根据自己的第一用户标识符确定的调度组。可选的，该至少一个目标调度组还可以包括该基于基站下的用户设备的第一用户标识符进行分组得到的多个调度组中与预设调度标识对应的第二调度组。进一步可选的，该至少一个目标调度组还可以包括第三调度组，其中，该第三调度组为除根据该第一用户标识符进行分组得到的多个调度组以外的备用调度组，该备用的第三调度组的调度信息为所述基站下接收该下行控制信息的多个用户设备均需接收的调度信息。也就是说，用户设备在接收基站下发的下行控制信息中的至少一个目标调度组的调度信息时，可以仅接收该用户设备的第一用户标识符对应的第一调度组的调度信息，或者接收该第一调度组的调度信息和第二调度组的调度信息，或者接收该第一调度组的调度信息和第三调度组的调度信息，或者接收该第一调度组的调度信息、第二调度组的调度信息以及第二调度组的调度信息，或者在其他实施例中，还可接收其他调度组的调度信息，本发明实施例不做限定。
具体的，该第一用户标识符可包括但不限于无线网络临时标识符(Radio Network Temporary Identity，简称“RNTI”)、集成电路卡识别码(Integrate circuit card identity，简称“ICCID”)、国际移动用户识别码(International Mobile Subscriber Identification Number，IMSI)、临时逻辑链路标识(Temporary Logical Link Identifier，简称“TLLI”)等等。其中，该RNTI可以具体为小区无线网络临时标识符(Cell Radio Network Temporary Identity，简称“C-RNTI”)、 寻呼无线网络临时标识符(Paging Radio Network Temporary Identity，简称“P-RNTI”)或随机接入无线网络临时标识符(Random Access Radio Network Temporary Identity，简称“RA-RNTI”)。
S102：所述用户设备在所述位置所对应的时间段内，通过接收机接收所述下行控制信息中所述至少一个目标调度组的调度信息。
在可选的实施例中，该用户设备在所述位置所对应的时间段外的其他时间，则可关闭所述接收机。具体的，用户设备在接收当前下行控制信息中所述至少一个目标调度组的调度信息时，可开启接收机(具体可以为射频接收机)，从而通过接收机接收该下行控制信息中目标调度组的调度信息，也就是说，在接收该目标调度组的调度信息之前，该接收机可以处于关闭状态，以降低用户设备的功耗，以及用户设备在接收到该下行控制信息中至少一个目标调度组的调度信息之后，也可关闭接收机，从而进一步降低该用户设备功耗。
具体的，基站可根据小区内的各个用户设备的第一用户标识符对小区内的所有用户设备进行分组，并将该下行控制信息划分为与该分组得到的调度组对应数目的调度字段，用于承载该小区内的各调度组的用户设备的调度信息，即每个分组调度组的调度信息在该下行控制信息中对应一个特定的位置，使得用户设备能够基于该特定的位置接收需要的调度信息。以第一用户标识符为IMSI为例，基站可基于基站下的各用户设备的IMSI对用户设备进行分组。假设将该基站小区内的用户设备分为10个调度组，分别对应0-9组，每个用户设备基于IMSI对应的调度组的组号可以取用户设备的IMSI的最后一位，也即：UE_Scheduling_group_No＝IMSI mod 10，该组号相同的用户设备对应同一个调度组，从而划分得到该10个调度组，并可将该调度组对应的组号作为该调度组的调度标识。在需要调度某一用户设备时，基站即可将该需要调度的用户设备的调度信息封装在下行控制信息中与该用户设备对应的调度组即第一调度组对应的位置。用户设备在接收下行控制信息时，则可在该第一调度组的调度信息在该下行控制信息中的位置所对应的时间段内接收该下行控制信息中的该第一调度组的调度信息，即仅需接收该下行控制信息中自己调度组的调度信息即可，而无需接收整个下行控制信息，从而降低了用户设备功耗。
进一步的，在接收到该第一调度组的调度信息之后，所述用户设备还可基 于该用户设备的第二用户标识符对所述第一调度组的调度信息进行校验；若对所述第一调度组的调度信息校验成功，则所述用户设备可将所述第一调度组的调度信息确定为所述用户设备需要的调度信息，从而基于所述第一调度组的调度信息发送或接收数据。其中，该目标调度组的调度信息可具体包括校验码和调度信息(信息部分)。
其中，所述第二用户标识符可包括但不限于RNTI(如C-RNTI、P-RNTI、RA-RNTI)、ICCID、IMSI、TLLI等等，该第一用户标识符与该第二用户标识符可以相同也可以不同，本发明实施例不做限定。
可选的，所述第一调度组的调度信息包括校验码如CRC序列码和第一调度信息，所述CRC序列码是所述基站对所述第一调度信息的第一CRC校验值与所述用户设备的第二用户标识符进行模2相加计算得到的校验序列；所述用户设备基于该用户设备的第二用户标识符对所述第一调度组的调度信息进行校验，可以具体为：所述用户设备对所述第二用户标识符与所述目标调度信息中的CRC序列码进行模2相加计算，得到所述第一CRC校验值；所述用户设备对所述第一调度信息进行CRC校验，得到第二CRC校验值；所述用户设备判断所述第二CRC校验值是否与所述第一CRC校验值相同；若相同，则所述用户设备确定对所述第一调度组的调度信息校验成功。
具体的，如图4所示，该下行控制信息中每个调度组的调度信息可分为两部分：信息部分和校验部分。其中，该信息部分包括需要调度的调度信息(即Scheduling Information，比如下行配置信息DL Allocation)，该校验部分为该调度信息携带的校验码(如基于RNTI对调度信息进行校验得到的CRC序列码，即CRC Masked by RNTI)。下面以基于第二用户标识符如RNTI对第一调度组的调度信息进行校验为例，对校验过程进行详细描述。信息部分如上述的第一调度信息的大小为n1比特，如表1中的下行配置信息DL Allocation中的内容(不包括RNTI)。该信息部分的具体内容可以如表2所示。
表2
Figure PCTCN2015082428-appb-000002
该校验部分为n2比特，其内容也即该CRC序列码为对信息部分的调度信息的CRC校验值(即第一CRC校验值)与该用户设备的RNTI的模2相加值，具体公式如下：
Figure PCTCN2015082428-appb-000003
用户设备在接收到第一调度组的调度信息之后，即可通过该用户设备的RNTI对该接收到的调度信息进行校验，其中，该接收的调度信息中携带有校验码如CRC序列码。具体的，用户设备使用自己的RNTI与该CRC序列码进行模2相加计算，得到该调度信息的CRC校验值即第一CRC校验值。此外，用户设备计算接收到的调度信息的CRC校验值即第二CRC校验值，如果计算得到的第二CRC校验值与上述第一CRC校验值相同，则表示当前接受的调度信息是该用户设备需要的调度信息，该用户设备即可基于该调度信息指示的时间、频率等资源信息接收或发送数据；否则，当两者不同时，则可表明该接收的调度信息不为用户设备所需要的调度信息，即该第一调度组的调度信息不用于调度该用户设备。
可选的，所述第一调度组的调度信息还可包括第一CRC校验值和携带第二用户标识符的第一调度信息，则可将该第一CRC校验值和第二用户标识符作为校验码；所述用户设备基于该用户设备的第二用户标识符对所述第一调度组的调度信息进行校验，还可以具体为：所述用户设备对所述第一调度信息进行CRC校验，得到第二CRC校验值；所述用户设备判断所述第二CRC校验值是否与所述第一调度组的调度信息中的第一CRC校验值相同；若所述第二CRC校验值与所述第一CRC校验值相同，则所述用户设备检测所述用户设备对应的用户标识符是否与所述第二用户标识符相同；若所述用户设备对应的用户标识符与所述第二用户标识符相同，则所述用户设备确定对所述第一调度组的调度信息校验成功。
在可选的实施例中，某些场景下，基站可能需要调度同一调度组下的多个用户设备，比如同一个调度组中的多个用户设备可能在同一时刻请求发送数据(比如多个智能电表可能同时请求发送本次计数)，因此，若基于预设的第二用户标识符对所述第一调度组的调度信息校验失败，则可表明该第一调度组中的调度信息不为该用户设备所需要的调度信息。此时，则可根据预设的DCI Interval，在基站下一次发送DCI时，再接收该第一调度组中的调度信息，并校验该调度信息是否为该用户设备所需要的调度信息，以便于在确定为该用户设备所需要的调度信息时，基于该调度信息接收或发送数据。
进一步的，在可选的实施例中，所述至少一个目标调度组包括用户设备对应的第一调度组，此外，该至少一个目标调度组还可包括基于第一用户标识符分组得到的多个调度组中与预设调度标识对应的第二调度组，也即，该用户设备需要接收该第一调度组的调度信息以及该第二调度组的调度信息。其中，所述多个调度组中每一个调度组对应一个调度标识，所述第二调度组中包括的至少一个用户设备在当前不需要被调度，此时所述第二调度组可被用于调度所述用户设备，即所述第二调度组为所述下行控制信息中未有属于该调度组的用户设备需要被调度的调度组。该第二调度组可以为该多个调度组中的一个或多个调度组。
具体的，当同一调度组下的多个用户设备需要被调度时，比如同一个调度组中的多个用户设备可能在同一时刻请求发送数据，此时，对于该需要调度的多个用户设备中的任一用户设备，基站可能会在下行控制信息中该第一调度组对应的位置发送该用户设备的调度信息，还可能在该下行控制信息中该第二调度组对应的位置发送该用户设备的调度信息。则该用户设备接收的该下行控制信息中的第一调度组中的调度信息则可能不为该用户设备自己需要的调度信息，该用户设备需要的调度信息可能在用户设备与基站预先协商好的其他调度组，比如该下行控制信息中预设调度标识对应的第二调度组。具体的，该预设调度标识对应的第二调度组可以是根据该第一调度组的调度标识获得的，如将该第一调度组的前M个调度组或后M个调度组作为该第二调度组，或者该M个调度组的位置还可以均匀分布于整个下行控制信息中，具体可由用户设备和基站预先协商得到，本发明实施例不做限定。则该用户设备可分别接收该下行控制信息中第一调度组的调度信息及第二调度组的调度信息，并在接收完成后 关闭接收机，以降低功耗。其中，M为大于0的整数。
进一步可选的，所述预设调度标识可以是所述用户设备根据预设算法计算出的，所述预设算法是所述用户设备与所述基站预先协商确定的。具体的，用户设备可使用一个基站和用户设备预先协商好的函数或公式来计算这个预设调度标识，如：
position＝func(UEID,Para1,Para2...)
其中，用户设备ID(UEID)是当前用户设备的用户标识符，可以是RNTI、IMSI等等，也可以是用户设备的第一用户标识对应的调度组即第一调度组的调度组号；Para1，Para2，表示可能的其他参数(可以不使用，即取0)，如可包括当前帧的帧号、时隙符号等等。Func表示采用的具体函数，可以是哈希函数或其他公式等。
进一步的，所述用户设备可基于所述第二户标识符对所述第二调度组的调度信息进行校验；若对所述第二调度组的调度信息校验成功，则所述用户设备将所述第二调度组的调度信息确定为所述用户设备需要的调度信息，并基于所述第二调度组的调度信息发送或接收数据。可选的，该对第二调度组的调度信息的校验操作可以是对第一调度组的调度信息校验失败，即确定得到该第一调度组的调度信息不为用户设备需要的调度信息之后再触发执行的。其中，该基于第二用户标识符对第二调度组的调度信息的校验操作与该基于第二用户标识符对该第一调度组的调度信息的校验操作类似，此处不再赘述。
进一步的，在可选的实施例中，所述至少一个目标调度组还包括第三调度组，所述第三调度组中的调度信息为所述基站下接收所述下行控制信息的多个用户设备均需接收的调度信息，即该用户设备还需要接收下行控制信息中该第三调度组的调度信息。具体的，该第三调度组为该下行控制信息如DCI中的备用调度组，如图5所示，除了N个调度组scheduling group(该N为根据第一用户标识符进行分组确定出的调度组数目)之外，每个下行控制信息如DCI消息中还可包括一定数目如1～2个备用的scheduling group(图5中仅示出一个备用的调度组，即backup group 0)，每次通过DCI发送调度信息时，如果某个调度组中有多余的用户设备需要被调度，多出用户设备的调度信息将置于下行控制信息中备用的scheduling group对应的位置发送。即小区中接收DCI 的多个用户设备(某些情况下，小区中的部分用户设备不会接收DCI，如有的用户设备处于休眠状态，则不会接收DCI，则可将该小区中除该不接收DCI的用户设备以外的其他用户设备作为该接收DCI的多个用户设备)除了接收用户设备自己的调度组及第一调度组的调度信息外，还都将接收该备用的第三调度组的调度信息。
进一步的，所述用户设备还可基于所述第二户标识符对所述第三调度组的调度信息进行校验；若对所述第三调度组的调度信息校验成功，则所述用户设备将所述第三调度组的调度信息确定为所述用户设备需要的调度信息，并基于所述第三调度组的调度信息发送或接收数据。可选的，该对第三调度组的调度信息的校验操作可以是对第一调度组的调度信息校验失败，即确定得到该第一调度组的调度信息不为用户设备需要的调度信息之后再触发执行的。其中，该基于第二用户标识符对第三调度组的调度信息的校验操作与该基于第二用户标识符对该第一调度组的调度信息的校验操作类似，此处不再赘述。
进一步可选的，该至少一个目标调度组还可包括该第一调度组、第二调度组以及第三调度组，即用户设备需要接收下行控制信息中该三个调度组的调度信息，并校验该三个调度组的调度信息中是否为自己需要的调度信息。具体的，可先校验该第一调度组的调度信息是否为需要的调度信息，在校验失败时选择校验第二或第三调度组的调度信息，比如校验第二调度组的调度信息，校验失败时再校验第三调度组的调度信息。当对某一调度组的调度信息校验成功时，则可将该调度信息确定为需要的调度信息，而无需再校验未校验的调度组的调度信息。例如，当对该第一调度组的调度信息校验成功时，该用户设备即可将该第一调度组的调度信息确定为需要的调度信息，以基于该第一调度组的调度信息发送或接收数据，而无需再校验第二和第三调度组的调度信息。
具体实施例中，所述用户设备确定每一个目标调度组的调度信息在基站发送的下行控制信息中的位置，可以具体为：用户设备获取目标调度组的调度标识、基站发送的下行控制信息中每一个调度组的调度信息的长度值和所述下行控制信息的位置信息；所述用户设备以所述目标调度组的调度标识、所述长度值以及所述下行控制信息的位置信息为依据，计算所述目标调度组的调度信息在所述下行控制信息中的目标偏移量；所述用户设备将所述目标偏移量指示的 位置作为所述目标调度组的调度信息在所述下行控制信息中的位置。进一步的，所述用户设备在所述位置所对应的时间段内，通过接收机接收所述下行控制信息中所述目标调度组的调度信息，可以具体为：所述用户设备通过接收机，并在所述目标偏移量指示的位置所对应的时间段内接收所述下行控制信息中所述目标调度组的调度信息。其中，该目标调度组的调度标识可具体为该目标调度组对应的调度组号。该下行控制信息的位置信息可具体包括该下行控制信息占用的频率、发送时间等等。
作为一种可选的实施方式，该下行控制信息中各个调度组的调度信息可以在时间资源上，即所述下行控制信息中各个调度组的调度信息可以是所述基站以时分复用的方式发送的。如图6所示，将该下行控制信息如DCI中包括N个调度组的调度信息，其中每个调度组的调度信息依次级联，则可获取得到当前DCI的整体下行调度信息，并以时分复用的方式发送给基站下接收该DCI的多个用户设备，该每个调度组的调度信息是在时间上连续映射的。其中，该下行控制信息的位置信息所指示的位置为所述下行控制信息的发送时间。
作为一种可选的实施方式，该下行控制信息中各个调度组的调度信息可以在频率资源上，即所述下行控制信息中各个调度组的调度信息还可以是所述基站以频分复用的方式发送的。如图7所示，假设有基站内有10(N＝10)个调度组，调度组1的调度信息映射到信道Channel l上，调度组2调度信息映射到Channel l+1上……以此类推。用户设备可以根据自己的调度标识如调度组号，确定自己的调度信息发送的Channel和偏移量，并在该信道下该偏移量指示的位置所对应的时间段内接收需要的调度组的调度信息。其中，该下行控制信息的位置信息所指示的位置为发送所述下行控制信息的频率或载波的位置。
作为一种可选的实施方式，该下行控制信息中各个调度组的调度信息也可以在时频资源上，即所述下行控制信息中各个调度组的调度信息还可以是所述基站以频分复用和时分复用相结合的方式发送的。如图8所示，假设有基站内有10(N＝10)个调度组，调度组1和调度组2的调度信息分别连续映射到Channel l上，调度组3和调度组4的调度信息分别连续映射到Channel l+1上……以此类推。用户设备可以根据自己的调度组号，确定自己的调度信息发送的信道Channel和偏移量，并只接收该信道下该偏移量指示的位置的调度组 的调度信息。
具体的，以下行控制信息以时分复用的方式发送给用户设备为例，用户设备可以根据自己的第一用户标识符如IMSI确定得到该用户设备所属的调度组的调度组号即调度标识，从而确定得到下行控制信息中该目标调度组的调度信息对应的位置。例如，假设调度组1(下行控制信息中的第一个调度组)距离下行控制信息起始位置的的比特偏移量为offset1，单个调度组的长度为n1+n2，则目标调度组如第i(i为小于或等于N的整数，且i大于0)个调度组距离该下行控制信息起始位置的比特偏移量即目标偏移量为offseti＝offset1+(i-1)*(n1+n2)。用户设备在接收调度信息时，只需要到offset_i的位置上接收n1+n2长度的消息即可，从而接收到该目标调度组的调度信息。在接收该目标调度组的调度信息之前以及之后的其他时刻，用户设备可以将自己的接收机关闭，以减少电源消耗。
需要说明的是，若基于第一用户标识符对基站下的多个用户设备进行分组得到的N个调度组中某些调度组在当前下行控制信息如DCI中并没有用户设备需要被调度，那么该组调度信息的位置仍将保留，但该位置上将不发送调度信息比特，如图9所示，以时分复用的方式发送DCI为例，调度组2没有用户设备被调度，则该DCI中调度组2的位置没有调度信息比特数。
在本发明实施例中，基于基站下的多个用户设备的第一用户标识符对所述多个用户设备进行分组得到的多个调度组，用户设备能够通过确定至少一个目标调度组的调度信息在基站发送的下行控制信息中的位置，实现接收该位置对应的时间段的该目标调度组的调度信息，比如仅接收该用户设备的第一用户标识符确定的第一调度组的调度信息，或者还同时接收预设调度标识对应的第二调度组或第三调度组的调度信息，即仅需接收该下行控制信息中的部分调度信息，而无需再接收整个下行控制信息，这就使得降低了用户设备功耗。进一步的，该用户设备在接收该目标调度组的调度信息的时间段以外的其他时间还可关闭接收机，使得能够进一步降低功耗，并提升了该用户设备的待机时间。
请参见图10，是本发明实施例提供的另一种信息调度方法的流程示意图，本发明实施例的所述方法可具体应用于基站中，具体的，该信息调度方法可包 括以下步骤：
S201：基站生成需要调度的用户设备的调度信息。
S202：所述基站确定所述用户设备对应的目标调度组，并将所述用户设备的调度信息封装于下行控制信息中所述目标调度组对应的位置，其中，所述下行控制信息包括多个调度组的调度信息，所述多个调度组由所述基站根据所述基站下的多个用户设备的第一用户标识符对所述多个用户设备进行分组得到且任一调度组包括至少一个用户设备。
需要说明的是，该下行控制信息中的多个调度组包括基站根据该基站下(即该基站对应的服务小区)的所有用户设备，也即基站所服务的所有用户设备的第一用户标识符对该所有用户设备进行分组得到的调度组，每个用户设备根据自己的第一用户标识符对应该分组中的一个调度组，从而该分组得到的任一调度组包括至少一个用户设备。其中，该多个调度组中的每个调度组的调度信息可具体用于调度该调度组中的至少一个用户设备。本发明实施例以每个调度组的调度信息仅调度该调度组中的一个用户设备为例进行说明。
可选的，该目标调度组可以是该需要调度的用户设备的第一用户标识符对应的第一调度组，即该用户设备根据自己的第一用户标识符进行分组确定的调度组；或者，该目标调度组还可以是该下行控制信息中根据第一用户标识符进行分组得到的多个调度组中预设调度标识对应的第二调度组；或者，该目标调度组还可以是该下行控制信息中的第三调度组，其中，该第三调度组为该下行控制信息中除根据该第一用户标识符进行分组得到的多个调度组以外的备用调度组，该备用的第三调度组的调度信息为所述基站下接收该下行控制信息的多个用户设备均需接收的调度信息。
其中，所述第一用户标识符可以具体为RNTI(如C-RNTI、P-RNTI、RA-RNTI)、ICCID、IMSI或TLLI等等，本发明实施例不做限定。
S203：所述基站向所述基站下的用户设备发送所述下行控制信息。
具体实施例中，所述基站确定所述用户设备对应的目标调度组，并将所述用户设备的调度信息封装于下行控制信息中所述目标调度组对应的位置，可以具体为：所述基站基于所述用户设备的第二用户标识符对所述用户设备的调度信息进行校验，并生成所述校验后的校验码；所述基站确定所述用户设备对应 的目标调度组，并将携带所述校验码的调度信息封装于下行控制信息中所述目标调度组对应的位置。
其中，所述第二用户标识符可以具体为RNTI(如C-RNTI、P-RNTI、RA-RNTI)、ICCID、IMSI或TLLI等等，且该第二用户标识符与该第一用户标识符可以相同也可以不同，本发明实施例不做限定。
具体实施例中，所述基站确定所述用户设备对应的目标调度组，并将携带所述校验码的调度信息封装于下行控制信息中所述目标调度组对应的位置，可以具体为：所述基站将所述用户设备的第一用户标识符对应的第一调度组确定为所述用户设备对应的目标调度组，并将携带所述校验码的调度信息封装于下行控制信息中所述第一调度组对应的位置。
具体的，基站可根据小区内的各个用户设备的第一用户标识符对小区内的所有用户设备进行分组，并将该下行控制信息划分为与该分组得到的调度组对应数目的调度字段，用于承载该小区内的各调度组的用户设备的调度信息，即每个分组调度组的调度信息在该下行控制信息中对应一个特定的位置，使得用户设备能够基于该特定的位置接收需要的调度信息。以第一用户标识符为IMSI为例，基站可基于基站下的各用户设备的IMSI对用户设备进行分组。假设将该基站小区内的用户设备分为10个调度组，分别对应0-9组，每个用户设备基于IMSI对应的调度组的组号可以取用户设备的IMSI的最后一位，也即：UE_Scheduling_group_No＝IMSI mod 10，该组号相同的用户设备对应同一个调度组，从而划分得到该10个调度组，并可将该调度组对应的组号作为该调度组的调度标识。在当前需要调度某一用户设备时，基站即可将该需要调度的用户设备的调度信息封装在下行控制信息中与该用户设备对应的调度组即第一调度组对应的位置。小区内的用户设备在接收下行控制信息时，则可在该第一调度组的调度信息在该下行控制信息中的位置所对应的时间段内接收该下行控制信息中的该第一调度组的调度信息，即仅需接收该下行控制信息中自己调度组的调度信息即可，而无需接收整个下行控制信息，从而降低了用户设备功耗。
在某些场景下，基站可能需要调度同一调度组下的多个用户设备，比如同一个调度组中的多个用户设备可能在同一时刻请求发送数据(比如多个智能电 表可能同时请求发送本次计数)，此时，该基站可按照预先设置的调度组分配规则为各调度用户设备分配调度组。
可选的，该下行控制信息中每个调度组的调度信息可仅用于调度该调度组中的一个用户设备。也就是说，当该DCI中的同一个调度组存在多个用户设备需要被调度时，该调度组的调度信息仅调度其中一个用户设备，其他的用户设备调度信息则可延迟到下一个DCI Interval进行发送，或下下个DCI Interval发送，即每次DCI中的该调度组的调度信息用于调度其中一个用户设备，直到完成所有的需要被调度的用户设备的信息调度。进一步的，可以预先为同一调度组的用户设备分配优先级，当某一调度组中有多个用户设备需要被调度时，该多个用户设备中优先级最高将最先被调度。若该多个用户设备的优先级相同，则基站当前可从该多个用户设备中随机选择一个用户设备来调度。
可选的，所述基站确定所述用户设备对应的目标调度组，并将携带所述校验码的调度信息封装于下行控制信息中所述目标调度组对应的位置，还可以具体为：所述基站将所述多个调度组中与预设调度标识对应的第二调度组确定为所述用户设备对应的目标调度组，并将携带所述校验码的调度信息封装于下行控制信息中所述第二调度组对应的位置；其中，所述多个调度组中每一个调度组对应一个调度标识，所述第二调度组中包括的至少一个用户设备在当前不需要被调度，此时所述第二调度组被用于调度所述用户设备。
具体的，当同一个调度组存在多个用户设备需要被调度时，还可以将该需要调度的用户设备的调度信息封装于当前DCI中预设调度标识对应的第二调度组所对应的位置。具体的，该预设调度标识对应的第二调度组可以是根据该第一调度组的调度标识获得的，比如该预设调度标识可以为该第一调度组的前M个调度组的调度标识或后M个调度组的调度标识，即可将该用户设备的调度信息封装于该第一调度组的前M个调度组或后M个调度组中没有自己调度组的用户设备需要调度，即空置的调度组中。或者该M个调度组的位置还可以均匀分布于整个DCI中，具体可由用户设备和基站预先协商得到，本发明实施例不做限定。其中，M为大于0的整数。
具体的，该预设调度标识可以是基站根据预设算法计算出的，所述预设算法是所述用户设备与所述基站预先协商确定的。即基站可使用一个基站和用户设备预先协商好的函数或公式来计算这个调度标识，如：
position＝func(UEID,Para1,Para2...)
其中，用户设备ID(UEID)是当前用户设备的用户标识符，可以是RNTI、IMSI等等，也可以是用户设备自己的调度组即第一调度组的调度组号；Para1，Para2，表示可能的其他参数(可以不使用，即取0)，如可包括当前帧的帧号、时隙符号等等。Func表示采用的具体函数，可以是哈希函数或其他公式等。
进一步可选的，该目标调度组还可以是第三调度组，所述基站确定所述用户设备对应的目标调度组，并将携带所述校验码的调度信息封装于下行控制信息中所述目标调度组对应的位置，还可具体为：所述基站将第三调度组确定为所述用户设备对应的目标调度组，并将携带所述校验码的调度信息封装于下行控制信息中所述第三调度组对应的位置，所述第三调度组中的调度信息为所述基站下接收所述下行控制信息的多个用户设备均需接收的调度信息。
具体的，该第三调度组为该下行控制信息如DCI中的备用调度组，如图5所示，除了N个调度组scheduling group之外，该DCI消息中还可包括一定数目如1～2个备用的scheduling group(如图5所示的backup group 0)。当同一个调度组存在多个用户设备需要被调度时，基站还可以将该需要调度的用户设备的调度信息封装于当前DCI中备用的第三调度组对应的位置。该基站对应的服务小区中接收DCI的多个用户设备(某些情况下，小区中的部分用户设备不会接收DCI，如有的用户设备处于休眠状态，则不会接收DCI，则可将该小区中除该不接收DCI的用户设备以外的其他用户设备作为该接收DCI的多个用户设备)除了接收用户设备自己的调度组的调度信息外，还都将接收该备用的第三调度组的调度信息。
可选的，所述基站基于该用户设备的第二用户标识符对所述用户设备的调度信息进行校验，并生成所述校验后的校验码，可以具体为：所述基站对所述用户设备的调度信息进行循环冗余校验CRC，得到第一CRC校验值；所述基站基于预设的第二用户标识符，对所述第二用户标识符与所述第一CRC校验值进行模2相加计算，得到CRC序列码，并将所述CRC序列码作为对所述用户设备的调度信息进行校验后的校验码。
具体的，如图4所示，每个调度组的调度信息可以分为信息部分和校验部分，该信息部分包括需要调度的调度信息(即Scheduling Information，比如下行配置信息DL Allocation)，该校验部分为该调度信息携带的校验码如CRC 序列码。其中，该CRC序列码为对该信息部分的调度信息的CRC校验值与该调度信息对应的用户设备的RNTI进行模2相加计算得到的值，即该CRC序列码计算公式为：
Figure PCTCN2015082428-appb-000004
从而计算得到该调度信息对应的CRC序列码，并将携带该CRC序列码的调度信息封装于下行控制信息中的目标调度组中发送给用户设备，使得用户设备能够基于自己的RNTI对该目标调度组中携带CRC序列码的调度信息进行校验，以根据该校验的校验结果确定该目标调度组的调度信息是否为该用户设备自己的调度信息。该用户设备对该目标调度组如第一调度组的调度信息的校验可具体参照图3对应实施例的相关描述，此处不再赘述。
进一步可选的，所述基站基于预设的第二用户标识符对所述用户设备的调度信息进行校验，并生成所述校验后的校验码，还可以具体为：所述基站对所述用户设备的调度信息进行CRC校验，得到第一CRC校验值；所述基站将所述第一CRC校验值和预设的第二用户标识符作为对所述用户设备的调度信息进行校验后的校验码。具体的，该需要调度的调度信息对应的校验码还可以包括对该调度信息的CRC校验值(即第一CRC校验值)和该被调度的用户设备的第二用户标识符如RNTI，则该基站可将携带该第一CRC校验值和RNTI的调度信息封装于下行控制信息中的目标调度组对应的位置，并将该下行控制信息发送给用户设备，使得所述用户设备能够根据该调度信息携带的第一CRC校验值和RNTI对该接收的调度信息进行校验。具体的，用户设备可对该接收的目标调度组的调度信息进行CRC校验，得到第二CRC校验值，并判断该第二CRC校验值是否与该调度信息携带的第一CRC校验值相同，以及判断该用户设备对应的RNTI是否与调度信息携带的RNTI相同；当CRC校验值和该RNTI均相同时，则可确认校验成功，用户设备可将该调度信息作为自己的调度信息。
进一步的，所述基站向所述基站下的用户设备发送所述下行控制信息，可以具体为：所述基站在所述下行控制信息的位置向所述基站下的用户设备发送所述下行控制信息。
作为一种可选的实施方式，该下行控制信息中各个调度组的调度信息可以在时间资源上，即所述下行控制信息中各个调度组的调度信息可以是所述基站 以时分复用的方式发送的。如图6所示，将该下行控制信息包括N个调度组的调度信息，其中每个调度组的调度信息依次级联，则基站可获取得到当前DCI的整体下行调度信息，并以时分复用的方式发送给基站下接收该DCI的多个用户设备，该每个调度组的调度信息是在时间上连续映射的。其中，所述下行控制信息的位置为所述下行控制信息的发送时间。
作为一种可选的实施方式，该下行控制信息中各个调度组的调度信息可以在频率资源上，即所述下行控制信息中各个调度组的调度信息还可以是所述基站以频分复用的方式发送的。如图7所示，假设有基站内有10(N＝10)个调度组，调度组1的调度信息映射到Channel l上，调度组2调度信息映射到Channel l+1上……以此类推。从而该基站可以以频分复用的方式将该下行控制信息发送给小区内的用户设备。其中，所述下行控制信息的位置为发送所述下行控制信息的频率或载波的位置。
作为一种可选的实施方式，该下行控制信息中各个调度组的调度信息也可以在时频资源上，即所述下行控制信息中各个调度组的调度信息还可以是所述基站以频分复用和时分复用相结合的方式发送的。如图8所示，假设有基站内有10(N＝10)个调度组，调度组1和调度组2的调度信息分别连续映射到Channel l上，调度组3和调度组4的调度信息分别连续映射到Channel l+1上……以此类推。从而该基站可以以时分复用和频分复用相结合的方式将该下行控制信息发送给小区内的用户设备。
需要说明的是，若基于第一用户标识符对基站下的所有用户设备进行分组得到的N个调度组中某些调度组在当前下行控制信息如DCI中并没有用户设备需要被调度，那么该组调度信息的位置仍将保留，但该位置上将不发送调度信息比特，如图9所示，以时分复用的方式发送DCI为例，调度组2没有用户设备被调度，则该DCI中调度组2的位置没有调度信息比特数。
在本发明实施例中，基于基站根据基站下的多个用户设备的第一用户标识符对所述多个用户设备进行分组得到的多个调度组，基站能够为小区内的需要调度用户设备分配调度组，从而将该需要调度的用户设备的调度信息封装于下行控制信息中为该用户设备分配的调度组对应的位置，并将该下行控制信息发送给用户设备，使得小区内的用户设备仅需接收该下行控制信息的部分调度组 的调度信息即可，而无需接收整个下行控制信息，使得降低了用户设备功耗，并提升了用户设备的待机时间。
