收发信息的方法、终端设备及网络设备
相关申请的交叉引用
本申请主张在2018年1月10日在中国提交的中国专利申请号No.201810023325.X的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种收发信息的方法、终端设备及网络设备。
背景技术
未来第五代(5Generation，5G)移动通信系统中，为了提高上下行链路的传输可靠性，对物理下行共享信道(Physical Downlink Shared Channel，PDSCH)和物理上行共享信道(Physical Uplink Shared Channel，PUSCH)引入了重复的机制，即每个PDSCH或PUSCH对应的数据块重复发送，重复次数可以是1、2、4或8次。在终端侧通过将接收到的重复数据合并解调来提高传输可靠性。
5G系统中，为了降低信令开销，提高无线资源利用率，降低基站能耗，新无线(New Radio，NR)提出了将系统信息分为两大类，一类为最小系统信息(minimum SI)，另一类为其他系统信息(other SI)。其中minimum SI包括主系统信息块(Master Information Block，MIB)和剩余最小系统信息(Remaining Minimum SI，RMSI)。此外，Other SI又根据有效范围分为Common SI和Cell specific SI，前者是几个小区Cell之间共享的，需要保持一致，后者是在一个Cell范围内的。
其中，minimum SI以周期性广播的方式发送给终端UE。other SI包含minimum SI以外所有的系统信息，Other SI可以像4G、长期演进(Long Term Evolution，LTE)一样包含多个系统信息块(System Information Block，SIB)。Other SI又称为On-demand SI，是基于UE的需求，由UE向基站请求(request)的。相关技术中已确定，UE通过随机接入(Random Access Channel，RACH) 过程的MSG1或MSG3来请求on demand SI，可以根据基站的配置或SI的类型来确定以MSG1还是以MSG3的方式来发送other SI的请求。基站在收到other SI请求后，对连接态的UE，可以通过专有信号(Dedicated signaling)将on demand SI发送给UE，对于空闲态(idle mode)或非激活态(inactive state)可以通过广播方式发送对应的on demand SI给UE。
LTE和NR都需要通过支持RACH过程来实现多种目的。其中NR通过支持RACH过程实现的目的可为：支持初始的空闲态UE连接到网络；无线资源控制(Radio Resource Control，RRC)重建；切换；下行数据到达但上行失步；上行数据达到但上行失步；UE从非激活态转到激活态；支持辅小区的上行同步获取；等等。
RACH过程可分为竞争的RACH过程和非竞争的RACH过程。竞争的RACH过程分为Message 1至message 4的四步接入，非竞争的RACH过程分为message 1和message 2的两步接入。竞争的RACH过程和非竞争的RACH过程中的message 2都是发送RAR，UE在RAR窗口内监听对应RA-RNTI的RAR。由于竞争的RACH过程存在UE在同样的PRACH资源发送同样的前导码的问题，因此在接收完message 2后UE还需要根据message2里的UL grant发送message 3，并且UE在message3上携带UE的标识，在message 3发送时同时启动竞争解决定时器timer。在竞争解决timer未超时前若接收到基站发送的message 4，则UE竞争解决成功。UE根据message4中携带的UE标识，可判断是不是自身的message4，从而判断是否竞争成功。
虽然5G中，对PDSCH和PUSCH引入了重复的机制，但对于非连接态的RACH过程，由于UE未与网络侧连接，因此UE和网络侧之间无法明确RACH过程中上行信息和下行信息的重复次数。相关技术中，尚未公开如何确定RACH过程中上下行信息的重复次数的方法。

图13为本公开实施例的网络设备的结构示意图之二。
具体实施方式
为了更清楚地说明本公开实施例的技术方案，下面将对本公开实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
参见图1所示，本公开实施例提供一种收发信息的方法，应用于终端设备，包括如下步骤：
步骤101：确定RACH过程中终端设备的上行信道或者上下行信道的重复次数。
应说明的是，终端设备的上行信道可为物理上行共享信道(Physical Uplink Shared Channel，PUSCH)、物理上行控制信道(Physical Uplink Control Channel，PUCCH)等。终端设备的下行信道可为物理上行共享信道(Physical Downlink Shared Channel，PDSCH)、物理上行控制信道(Physical Downlink Control Channel，PDCCH)等。上行信道或者下行信道的重复次数例如为1、2、4或8次。
终端设备在确定RACH过程中其上行信道或者上下行信道的重复次数时，可直接根据网络侧通过广播消息发送的指示信息确定。具体的，参见图2所示，步骤101可包括：
步骤1011：接收网络设备发送的指示信息；
步骤1012：根据该指示信息，确定RACH过程中终端设备的上行信道或者上下行信道的重复次数。
其中，该指示信息可用于指示RACH过程中终端设备的上下行信道的重复次数。例如，采用2bit指示信息指示终端设备的PDSCH和PUSCH，以及未来可能的PUCCH和PDCCH的重复次数。
该指示信息可包括第一指示信息和第二指示信息，其中，该第一指示信息用于指示RACH过程中终端设备的上行信道的重复次数，第二指示信息用于指示RACH过程中终端设备的下行信道的重复次数。例如，采用2bit指示信息指示终端设备的PDSCH(或PDCCH)的重复次数，采用2bit指示信息指示终端设备的PUSCH(或PUCCH)的重复次数，即每个信道分别采用Nbit指示信息指示对应的重复次数。
进一步的，当网络侧通过广播消息发送指示信息时，该广播消息中可携带有终端设备的标识信息或者终端设备所在组的标识信息，用于对应终端设备使用广播消息中的指示信息确定重复次数。例如若某UE接收到的广播消息中携带有其标识信息或者其所在组的标识信息，则该UE可使用该广播消息中的指示信息确定对应的重复次数。
进一步的，当网络侧通过广播消息发送指示信息时，该指示信息可包括 在广播消息的如下信息中的至少一项信息中：主系统信息块MIB、系统信息块SIB1、剩余最小系统信息RMSI或其他系统信息OSI。
本公开实施例的适用场景例如为5G、eLTE或者其它有类似配置的场景。
步骤102：在RACH过程中采用所述重复次数发送上行信息，或者发送上行信息和接收下行信息。
需指出的是，若广播消息中的指示信息仅指示了上行信道的重复次数，没有区分上下行，则可采用与上行信道的重复次数一样的重复次数接收下行信息，或者盲检下行信息。该上行信息可为上行控制信号或上行数据，该下行信息可为下行控制信号或下行数据。该上行信息和下行信息可对应于RACH过程中的msg.1、2、3、4、5消息。
本公开实施例的收发信息的方法，通过确定RACH过程中终端设备的上行信道或者上下行信道的重复次数，在RACH过程中采用所述重复次数发送上行信息，或者发送上行信息和接收下行信息，从而能够明确如何确定RACH过程中上下行信息的重复次数。
本公开实施例中，当根据网络侧通过广播消息发送的指示信息确定相应的重复次数时，该指示信息除可采用上述指示重复次数的方式外，还可用于指示不同前导码组使用的重复次数，即指示RACH过程中使用前导码组A中的前导码的终端设备和使用前导码组B中的前导码的终端设备的上行信道或者上下行信道的重复次数。相关技术中对于随机接入的前导码有分组，分别为前导码组A(group A)和前导码组B(group B)。该group A和group B可分别表示不同的路损或者信道状况。
具体的，该指示信息指示不同前导码组使用的重复次数时，可采用分开编码或者联合编码。当采用分开编码时，该指示信息可包括第三指示信息和第四指示信息，其中，该第三指示信息用于指示RACH过程中使用前导码组A中的前导码的终端设备的上下行信道的重复次数，该第四指示信息用于指示RACH过程中使用前导码组B中的前导码的终端设备的上下行信道的重复次数。例如，该第三指示信息可为2bit信息，当为0时对应于1&1次，当为1时对应于2&4次；该第四指示信息可为2bit信息，当为0时对应于2&2次，当为1时对应于4&8次(其中“&”之前对应于上行信道的重复次数，“&” 之后对应于下行信道的重复次数)。
当采用分开编码时，该指示信息可包括第五指示信息、第六指示信息、第七指示信息和第八指示信息，其中，该第五指示信息用于指示RACH过程中使用前导码组A中的前导码的终端设备的上行信道的重复次数，该第六指示信息用于指示RACH过程中使用前导码组A中的前导码的终端设备的下行信道的重复次数，该第七指示信息用于指示RACH过程中使用前导码组B中的前导码的终端设备的上行信道的重复次数，该第八指示信息用于指示RACH过程中使用前导码组B中的前导码的终端设备的下行信道的重复次数。例如，该第五、第六、第七和第八指示信息可分别为2bit信息。
当采用联合编码时，该指示信息可用于指示RACH过程中使用前导码组A中的前导码的终端设备的上下行信道的重复次数，以及RACH过程中使用前导码组B中的前导码的终端设备的上下行信道的重复次数。例如，该指示信息可为1、2、3或4bit信息，当为3bit信息时，指示的重复次数组合可为如下8种：1&1、1&2、2&2、2&4、2&8、4&4、4&8和8&8(其中“&”之前对应于使用前导码组A中的前导码的终端设备的上下行信道的重复次数，“&”之后对应于使用前导码组B中的前导码的终端设备的上下行信道的重复次数)；当为2bit信息时，指示的重复次数组合可上述8种中的4种，比如较重要的1&1、1&2、2&4和4&8；当为1bit信息时，指示的重复次数组合可上述8种中的2种，比如2&4和4&8。
当采用联合编码时，该指示信息可包括第九指示信息和第十指示信息，其中，该第九指示信息用于指示RACH过程中使用前导码组A中的前导码的终端设备的上行信道的重复次数和RACH过程中使用前导码组B中的前导码的终端设备的上行信道的重复次数，该第十指示信息用于指示RACH过程中使用前导码组A中的前导码的终端设备的下行信道的重复次数和RACH过程中使用前导码组B中的前导码的终端设备的下行信道的重复次数。例如，该第九指示信息可为1、2、3或4bit信息，当为3bit信息时，指示的重复次数组合可为如下8种：1&1、1&2、2&2、2&4、2&8、4&4、4&8和8&8(其中“&”之前对应于使用前导码组A中的前导码的终端设备的上行信道的重复次数，“&”之后对应于使用前导码组B中的前导码的终端设备的上行信道 的重复次数)；当为2bit信息时，指示的重复次数组合可上述8种中的4种，比如较重要的1&1、1&2、2&4和4&8；当为1bit信息时，指示的重复次数组合可上述8种中的2种，比如2&4和4&8；该第十指示信息的指示方式可与第九指示信息的指示方式相同，在此不再赘述。
本公开实施例中，为了更精准确定相应重复次数，终端设备可根据测量性能判定上行信道的重复次数。具体的，参见图3所示，步骤101可包括：
步骤1013：接收网络设备发送的门限信息；其中，该门限信息中包括用于确定RACH过程中终端设备的上行信道的重复次数或次数等级的至少一个测量性能门限值；该次数等级可以按照与重复次数一一对应的方式划分，或者按照重复次数分组的方式划分；可选的，此门限信息可通过广播消息或RRC消息(比如RRC配置消息、RRC重构消息)由网络侧发送给终端设备；
步骤1014：根据该至少一个测量性能门限值，确定RACH过程中终端设备的上行信道的重复次数。
其中，步骤1014中确定的次数等级可是由终端设备根据该至少一个测量性能门限值直接确定，或者是由终端设备根据已确定的次数等级确定，该已确定的次数等级是由终端设备根据该至少一个测量性能门限值确定。此实施例中涉及的测量性能可包括：参考信号接收功率(Reference Signal Receiving Power，RSRP)、RSRQ(Reference Signal Receiving Quality)表示参考信号接收质量、信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)、信道质量指示(Channel Quality Indicator，CQI)等。对应的测量性能门限值可根据实际情况设定，以便根据测量性能门限值精准确定相应的上行信道的重复次数。
对应的，步骤102具体包括：
在RACH过程中采用确定的重复次数发送上行信息，和盲检下行信息。
需要说明的是，由于此实施例中网络侧不知道终端设备使用重复次数，因此对应的，在终端设备发送上行信息时，网络侧直接盲检上行控制信号或者上行数据。
进一步，为了实现终端设备和网络侧之间同步使用的重复次数，在根据测量性能门限值确定上行信道的重复次数的前提下，终端设备还可接收网络 设备发送的指示信息，该指示信息用于指示RACH过程中使用前导码组A中的前导码的终端设备和使用前导码组B中的前导码的终端设备的上行信道或者上下行信道的重复次数，以便终端设备选择已确定的上行信道的重复次数对应的前导码组中的前导码进行随机接入，而网络侧根据终端设备使用的前导码所在的前导码组判定终端设备使用的重复次数。具体的，在图3所示的实施例的基础上，参见图4所示，步骤102之前，所述方法还可包括：
步骤103：接收网络设备发送的指示信息；其中，该指示信息用于指示RACH过程中使用前导码组A中的前导码的终端设备和使用前导码组B中的前导码的终端设备的上行信道或者上下行信道的重复次数；此步骤103可处于步骤1013和步骤1014之前或之后；
步骤104：根据所述指示信息，选择上行信道的重复次数对应的前导码组中的前导码。
对应的，步骤102具体为：
在RACH过程中利用选择出的前导码，并采用上行信道的重复次数发送上行信息，和接收下行信息。
需要说明的是，此实施例中，网络侧可根据判定出的终端设备使用的重复次数(借助终端设备使用的前导码所在的前导码组)发送下行信息，和接收上行信息。这样，可实现终端设备和网络侧之间同步使用的重复次数。
本公开实施例中，为了实现终端设备和网络侧之间同步使用的重复次数，在根据测量性能门限值确定上行信道的重复次数的前提下，终端设备还可接收网络设备发送的PRACH资源配置信息，该PRACH资源配置信息中包括对应于不同上下行信道的重复次数或次数等级的PRACH资源分组，以便终端设备选择已确定的上行信道的重复次数对应的PRACH资源进行随机接入，而网络侧根据终端设备使用的PRACH资源判定终端设备使用的重复次数。
可选的，该PRACH资源配置信息可通过广播消息或RRC消息(比如RRC配置消息、RRC重构消息)由网络侧发送给终端设备。PRACH资源按照上下行信道的重复次数或次数等级进行划分，可包括前导码码字资源、时域资源、频域资源、空域资源beam、带宽部分bandwidth part(BWP)资源等。
具体的，在图3所示的实施例的基础上，参见图5所示，步骤102之前， 所述方法还可包括：
步骤105：接收网络设备发送的PRACH资源配置信息，其中，该PRACH资源配置信息中包括对应于不同上下行信道的重复次数或次数等级的PRACH资源分组；此步骤105可处于步骤1013和步骤1014之前或之后；
步骤106：选择确定的上行信道的重复次数对应的PRACH资源。
对应的，步骤102具体为：
在RACH过程中利用选择出的PRACH资源，并采用上行信道的重复次数发送上行信息，和接收下行信息。
需要说明的是，此实施例中，网络侧可根据判定出的终端设备使用的重复次数(借助终端设备使用的PRACH资源)发送下行信息，和接收上行信息。这样，可实现终端设备和网络侧之间同步使用的重复次数。
本公开实施例中，当网络侧例如基站不广播重复次数时，终端设备可将预设重复次数中的最大重复次数确定为RACH过程中其上行信道的重复次数。具体的，步骤101可包括：
终端设备将预设重复次数中的最大重复次数确定为RACH过程中其上行信道的重复次数。
对应的，步骤102可包括：
在RACH过程中终端设备采用该上行信道的重复次数发送上行信息，和盲检下行信息。
此外，本公开实施例中，终端设备还可根据预设方式，确定RACH过程中其上下行信道的重复次数。其中，该预设方式为如下方式中任意一种：
终端设备在RACH过程之前的连接态配置的重复次数；
在RACH过程之前通过RRC信令为终端设备配置的重复次数，包括用于至少一项如下消息的重复次数：msg.1、2、3、4、5；
预定义的或者默认的重复次数；此预定义的或者默认的重复次数可以是协议约定，或者网络侧预先配置。
需要说明的是，若上述指示信息包括在广播消息的OSI中，则在获取OSI之前，RACH过程可采用上述预设方式确定上下行信道的重复次数。
参见图6所示，本公开实施例还提供了一种收发信息的方法，应用于网 络设备，包括如下步骤：
