Description

传输信息的方法、网络设备和终端设备 技术领域
本申请涉及通信领域，并且更具体地，涉及一种传输信息的方法、网络设备和终端设备。
背景技术
基于包的数据流通常是突发性的，在一段时间内有数据传输，但在接下来的一段较长时间内没有数据传输。在没有数据传输的时候，可以通过停止接收PDCCH(此时会停止PDCCH盲检)来降低功耗，从而提升电池使用时间。这就是非连续接收(Discontinuous Reception，简称为“DRX”)的由来。
DRX的基本机制是为处于无线资源控制连接(RRC_CONNECTED)状态的终端设备配置一个DRX周期(cycle)。如图1所示，DRX cycle由激活期(On Duration)和休眠期(Opportunity for DRX)组成。在“On Duration”时间内，终端设备监听并接收物理下行控制信道(Physical Downlink Control Channel，简称为“PDCCH”)；在“Opportunity for DRX”时间内，终端设备不接收PDCCH以减少功耗。在时域上，时间被划分成一个个连续的DRX Cycle。
为了允许终端设备在HARQ往返时间(Round-Trip Time简称为“RTT”)处于休眠期，减少功耗。长期演进(Long Term Evolution，简称为“LTE”)定义了一个混合自动重传请求往返时间定时器(HARQ RTT Timer)。其中，对FDD而言，对于一个HARQ进程，HARQ RTT Timer的大小固定为8个子帧。对TDD而言，对于一个HARQ进程，HARQ RTT Timer的大小为k+4个子帧，其中k值为下行传输与对应HARQ反馈之间的时间间隔(k值参考TS36.213的Table 10.1.3.1-1)。
但是，随着系统的进一步演进，基站在下行调度的同时指示终端设备反馈应答/非应答(ACK/NACK)的时间点，即从终端设备收到下行数据到终端设备反馈ACK/NACK的时间长度不再固定是4个子帧，而是灵活配置的。此时，固定HARQ RTT Timer达不到预期的效果。

应理解，图2和图3只是示例性结合网络设备和终端设备描述了各个实施例。其中，网络设备可以是用于与终端设备进行通信的设备，网络设备可以包括基站或者具有基站功能的网络侧设备。例如，如图2所示，网络设备可以是LTE系统中的演进型基站(Evolved Node B，eNB或eNodeB)，网络设备还可以是GSM系统或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，或者网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络侧设备等。

图4是本发明实施例的传输信息的方法300的示意性流程图。
310，确定配置信息，用于终端设备确定混合自动重传请求往返时间定时器(HARQ RTT Timer)的时间长度。
具体而言，网络设备确定配置信息，该配置信息用于终端设备确定HARQ RTT Timer的时间长度。
例如，该配置信息包括该HARQ RTT Timer的时间长度中的部分或者全部信息，终端设备根据该配置信息确定该HARQ RTT Timer的时间长度。
又例如，该配置信息只是一个指示信息，在协议中为HARQ RTT Timer配置多个时间长度，终端设备根据该指示信息以及能力信息，在该多个时间长度中选择，等等。在本发明实施例中，该HARQ RTT Timer的时间长度可以包括至少一个时间单元，可选地，该配置信息还可以包括该HARQ RTT Timer的时间单元的长度信息。换句话说，网络设备通过该配置信息不仅可以配置终端设备HARQ RTT Timer的时间长度，还可以配置HARQ RTT Timer的时间单元的信息。可选的，该配置信息只包含数值信息，HARQ RTT Timer的时间单位由终端设备根据场景选择，例如在使能短TTI场景，时间单元为短TTI，即至少一个连续符号的长度，例如短TTI长度为2符号；在非使能短TTI场景，时间单元为子帧。
可选地，该HARQ RTT Timer的时间单元的长度为一个子帧的长度，或者为至少一个连续符号的长度。即终端设备通过网络设备发送该配置信息，可以确定该HARQ RTT Timer的时间长度的时间单元的长度为一个子帧的长度，或者为至少一个连续符号的长度。
例如，该HARQ RTT Timer的时间单元的长度为2个连续符号的长度、5个连续符号的长度或者7个连续符号的长度。
又例如，该HARQ RTT Timer的时间单元的长度可以是传输时间间隔(Transmission Time Interval，简称为“TTI”)的长度。
可选地，LTE中基本TTI是1ms，最小传输时间间隔也是1ms，即该HARQ RTT Timer 的时间单元也是1ms。当终端设备进入短TTI模式时，TTI长度可以是一个或多个符号长度，此时HARQ RTT Timer的时间单元也是短TTI的长度，即一个或多个符号长度。
应理解，在本发明实施例中，该HARQ RTT Timer的时间单元的长度可以是一个子帧的长度，也可以是一个PDCCH子帧的长度，也可以是多个子帧或者多个PDCCH子帧的长度；该HARQ RTT Timer的时间单元的长度可以是多个连续的符号，也可以是非连续的符号。本申请对此不作限定。
因此，本申请提供的传输信息的方法，通过配置信息，使得终端设备的HARQ RTT Timer的时间长度以时间单元为单位，能够在保证数据传输时延的要求下，降低功耗。
还应理解，本发明实施例中的HARQ RTT Timer的时间单元信息可以和该配置信息关联，也可以在协议中进行规定。本申请对此不作限定。
例如，在使能短TTI场景，时间单元为短TTI，即至少一个连续符号的长度。可选地，短TTI长度为2符号。
又例如，在非使能短TTI场景，时间单元为子帧。
应理解，本发明实施例中的使能短TTI场景，可以是连续的一段时间内数据传输采用短TTI场景，可以由网络设备进行配置，也可以通过协议进行规定。
还应理解，该配置信息可以配置HARQ RTT Timer的时间单元的长度，也可以配置其它定时器的时间单元的长度。本申请对此不作限定。
例如，当HARQ RTT Timer超时后启动drx-RetransmissionTimer，如果该Drx-Retransmiss ionTimer仍然以子帧为单位进行设置，则有可能会导致激活时间过长从而费电，因此，该Drx-RetransmissionTimer也可以短TTI为时间单元进行配置。
又例如，On Duration Timer，Inactivity Timer等等。
还应理解，该配置信息可以配置HARQ RTT Timer的时间单元的长度，其它定时器可以继续以子帧为单位的长度。本申请对此不作限定。可选的，以上DRX相关Timer的时间单位由终端设备根据场景选择，例如在使能短TTI场景，时间单元为短TTI，即至少一个连续符号的长度；在非使能短TTI场景，时间单元为子帧。
例如，终端设备在一个无线帧中间的某个子帧接收到调度命令(如新传上行或新传下行调度命令)，可以启动或重启Inactivity Timer。可选的，该Inactivity Timer以2个符号为长度单元，总长为16个符号长度，超时时刻可能不是一个子帧的最后一个符号。此时超时时刻可以规定为在所在子帧的结束时刻超时，或者在所在子帧的起始时刻超时，即在时间上向前或后的一个子帧对齐。可选的，在启动或重启Inactivity Timer时，如果启动/重启该Inactivity Timer后超时的子帧位置，与不启动/不重启该Inactivity Timer后超时的子帧位置为同一个子帧，则可以不启动或不重启该Inactivity Timer。
应理解，本申请提供的方法，可以通过配置信息指示终端设备启动HARQ RTT Timer，也可以指示终端设备不启动HARQ RTT Timer。本申请对此不作限定。
例如，当配置信息关联的时间单元的长度小于和/或等于特定值时，将HARQ RTT Timer禁止掉，例如1ms。即在接收到下行调度命令或者发送上行数据的子帧直接启动Drx-RetransmissionTimer；或者将HARQ RTT Timer和Drx-RetransmissionTimer都禁止掉，通过其它Timer如Inactivity Timer来保证终端设备接收重传调度命令。本申请对此不作限定。
下面结合图5至图7分别以下行HARQ RTT Timer和上行HARQ RTT Timer为例，对终端设备通过该配置信息确定HARQ RTT Timer的具体实现进行说明。
在本申请的一个实施例中，该HARQ RTT Timer为下行HARQ RTT Timer。
下行数据的HARQ重传一般采用异步方式，即终端设备接收网络设备的初传数据与重传数据之间没有固定的timing关系。LTE定义的HARQ RTT Timer，允许终端设备从前一次下行传输算起，并在该HARQ RTT Timer超时后，才开始监听下行重传数据的PDCCH。下行传输可以是基于动态调度，即终端设备通过监听PDCCH获得本次数据传输的调度信息；也可以是基于半静态调度，即网络设备周期地在固定时频资源上向终端设备发送数据。
例如，在FDD系统中，HARQ RTT Timer的大小固定为8个子帧。
图5是FDD系统中的下行HARQ RTT Timer的示意性结构图。
如图5所示，当子帧1有下行数据到达时，从子帧1开始启动HARQ RTT Timer，即终端设备处于非激活时间不进行PDCCH盲检；终端设备在子帧5反馈NACK，HARQ RTT Timer在子帧8超时后，从子帧9开始启动drx-Retransmission Timer，即终端设备处于激活时间，开始盲检PDCCH；终端设备在下一个无线帧的子帧3位置收到下行重传调度信息。
换句话说，在FDD系统中默认的下行HARQ时序关系是：网络设备在子帧n初传下行数据，终端设备在子帧n+4进行反馈，网络设备最早可以在子帧n+8重传下行数据。即下行HARQ RTT Timer在FDD中固定为8个子帧。其中，包括从终端设备收到下行数据到终端设备反馈ACK/NACK的4个子帧，和从终端设备反馈后到下行重传调度的4个子帧。
但是，随着系统的进一步演进，固定的下行HARQ RTT Timer不再适用。例如，灵活HARQ场景，即基站在下行调度中，同时指示终端设备反馈ACK/NACK的时间点，即从终端设备收到下行数据到终端设备反馈ACK/NACK的时间长度不再固定是4个子帧，而是灵活配置的，此时HARQ RTT Timer的长度需要同步调整，才能达到预期的降低功耗的效果。
本发明实施例提供的传输信息的方法，通过配置信息为终端设备灵活配置下行HARQ RTT Timer，能够进一步降低功耗。
图6是本发明实施例的传输信息的下行HARQ RTT Timer示意性结构图。
如图6所示，在本申请的下行灵活HARQ中，下行初传和终端设备反馈的时间间隔(T2)是一个变量，不再固定为4个子帧。同样，从终端设备反馈到下行重传的最短时间间隔(T3)也不一定是4个子帧。HARQ RTT Timer的时间长度(T1)为T2+T3。该下行HARQ RTT Timer超时后，启动DRX-重传定时器，开始检测PDCCH，以获得可能的下行重传数据。
可选地，终端设备根据该配置信息，确定该HARQ RTT Timer的时间长度；终端设备根据接收下行初传数据的子帧位置，以及该HARQ RTT Timer的时间长度运行该HARQ RTT Timer。
需要说明的是，本发明实施例中的时间间隔为两个时刻之间的间隔，是两个时刻的相对值，例如，子帧n和子帧n+k的时间间隔为k个子帧。
具体而言，如图6所示，网络设备在子帧1初传下行数据，终端设备在子帧5向网络设备发送反馈信息，则下行初传和终端设备反馈的时间间隔表示子帧1和子帧5之间的间隔，为4个子帧。
应理解，本申请中的时间间隔可以以一个子帧为粒度，也可以以多个子帧为粒度，还可以以一个或者多个符号长度为粒度，还可以以TTI长度为粒度。还应理解，本申请中 的时间间隔也可以为其它形式。例如，子帧n和子帧n+k的时间间隔为k个子帧，其中，该k个子帧可以包括子帧n，但不包括子帧n+k。本申请对此不作限定；又例如，子帧n和子帧n+k的时间间隔为k个子帧，其中，该k个子帧可以包括子帧n+k，但不包括子帧n。
本申请提供的传输信息的方法，网络设备通过该配置信息，为终端设备动态配置下行HARQ RTT Timer的时间长度，能够在保证数据传输时延的要求下，降低功耗。
可选地，该配置信息包括第一时间间隔，该第一时间间隔表示第一时刻至第二时刻之间的间隔，该第一时刻为该网络设备初传第一下行数据的时刻，该第二时刻为该网络设备重传该第一下行数据的最早的时刻。
具体地，网络设备通过该配置信息为终端设备配置HARQ RTT Timer。即终端设备根据该配置信息可以直接将该第一时间间隔确定为该下行HARQ RTT Timer的时间长度。
例如，如图6所示，该第一时间间隔为子帧1到子帧8之间的间隔，即该第一时间间隔为7个子帧，终端设备根据该第一时间间隔和第一时刻，确定HARQ往返定时器的时间为子帧1到子帧7。
可选地，该配置信息包括该第二时间间隔，该第二时间间隔表示第一时刻至第三时刻之间的间隔，该第一时刻为该网络设备初传该第一下行数据的时刻，该第三时刻为该终端设备发送该第一下行数据的非应答NACK反馈信息的时刻。
具体地，终端设备根据该第二时间间隔，确定该下行HARQ RTT Timer的时间长度。例如，终端设备可以根据网络设备配置的第二时间间隔和静态/半静态配置的第三时间间隔，或协议规定的固定第三时间间隔，或按预定规则确定第三时间间隔，例如第三时间间隔等于第二时间间隔，确定该下行HARQ RTT Timer的时间长度。
可选地，该配置信息还包括第三时间间隔，该第三时间间隔表示该第三时刻至该第二时刻之间的间隔，该第三时刻为该终端设备发送该第一下行数据的非应答NACK反馈信息的时刻，该第二时刻为该网络设备重传该第一下行数据的最早的时刻。
具体地，终端设备根据该第三时间间隔，确定该下行HARQ RTT Timer的时间长度。例如，终端设备可以根据网络设备配置的第二时间间隔和网络设备配置的第三时间间隔，确定该下行HARQ RTT Timer的时间长度。
例如，如图6所示，该第二时间间隔为子帧1到子帧5之间的间隔，即该第一时间间隔为4个子帧；该第三时间间隔为子帧5到子帧8之间的间隔，即该第一时间间隔为3个子帧；终端设备根据该第二时间间隔、第三时间间隔和第一时刻，确定HARQ往返定时器的时间为子帧1到子帧7。
因此，本申请提供的传输信息的方法，网络设备通过该配置信息，为终端设备动态配置下行HARQ RTT Timer的时间长度，能够在保证数据传输时延的要求下，降低功耗。
上述配置信息，可以包括第一时间间隔、第二时间间隔、第三时间间隔的一个或多个。
应理解，在本发明实施例中，该第一时间间隔、该第二时间间隔或者该第三时间间隔可以由网络设备动态配置，例如，下行控制信道(DCI)信息；也可以半静态配置，例如，无线资源控制(RRC)信息；也可以通过媒体接入控制层控制元素MAC CE配置；也可以通过协议进行固定配置或指示计算规则，本申请对此不作限定。
在本申请的另一个实施例中，该HARQ RTT Timer为上行HARQ RTT Timer。
现有LTE系统中，HARQ协议在时域上可以分为同步(synchronous)和异步(asynchronous)两类。其中，同步上行HARQ意味着终端设备只能在前一次传输之后的固定时刻重传数据，即终端设备按照协议规定在固定时刻向基站发送重传数据，上行重传无需基站发送调度命令。例如，在FDD系统中，终端设备在子帧n向基站发送初传数据，基站在子帧n+4向终端设备反馈NACK，则在无需基站调度的情况下终端设备在子帧n+8向基站发送重传数据。
然而，异步上行HARQ意味着重传可以发生在任一时刻，即当终端设备向网络设备反馈NACK后，并不会在固定子帧发送重传数据，而是需要先接收网络设备通过PDCCH发送的重传调度信息，在获得调度信息后终端设备才会向基站发送重传数据。
本发明实施例提供的传输信息的方法，通过配置信息为终端设备灵活配置上行HARQ RTT Timer，能够进一步降低功耗。
图7是本发明实施例的传输信息的上行HARQ RTT Timer示意性结构图。
如图7所示，终端设备在子帧1接收上行初传调度，调度信息中指示在子帧n+4发送上行初传数据。子帧1启动上行HARQ RTT Timer。该上行HARQ RTT Timer在子帧8超时，在子帧9启动DRX-重传定时器，尝试获得可能的上行重传调度信息；如图终端设备在下一帧子帧0接收到上行重传调度信息，调度信息中指示在子帧n+3发送重传数据，则终端设备在下一帧的子帧3发出上行重传数据。
应理解，在本申请的上行灵活HARQ中，上行初传调度和上行初传的时间间隔(T3)是一个变量，上行初传和终端设备反馈的时间间隔(T4)也可能是一个变量。HARQ RTT Timer的时间长度为该T3+T4的时间长度，同样也是一个变量。需要注意的是，对于半静态调度的上行传输，终端设备可以周期地在预配置的时频资源上发送数据，无需PDCCH调度。此时HARQ RTT Timer的时间长度为T4的长度。
因此，本申请提供的传输信息的方法，网络设备通过该配置信息，为终端设备动态配置上行HARQ RTT Timer的时间长度，能够在保证数据传输时延的要求下，降低功耗。
可选地，该配置信息包括第四时间间隔，该第四时间间隔表示第四时刻至第五时刻之间的间隔，该第四时刻为该终端设备开始接收第一上行数据的上行初传调度信息的时刻，该第五时刻为该终端设备最早开始接收该第一上行数据的上行重传调度信息的时刻。
具体地，网络设备通过该配置信息为终端设备配置上行HARQ RTT Timer。例如，如图7所示，终端设备根据该配置信息可以直接将该第四时间间隔确定为该上行HARQ RTT Timer的时间长度。
可选地，该配置信息包括该第五时间间隔，该第五时间间隔表示第四时刻至第六时刻之间的间隔，该第四时刻为该终端设备开始接收第一上行数据的上行初传调度信息的时刻，该第六时刻为该终端设备开始传输该第一上行数据的时刻。
具体地，终端设备根据该第五时间间隔，确定该上行HARQ RTT Timer的时间长度。例如，终端设备可以根据网络设备配置的第五时间间隔和静态/半静态配置的第六时间间隔，或协议规定的固定第六时间间隔，或按预定规则确定第六时间间隔，例如第六时间间隔等于第五时间间隔，确定该上行HARQ RTT Timer的时间长度。
可选地，该配置信息还包括第六时间间隔，该第六时间间隔表示该第六时刻至第五 时刻之间的间隔，该第六时刻为该终端设备初传该第一上行数据的时刻，该第五时刻为该终端设备接收该第一上行数据的上行重传调度信息的最早的时刻。
具体地，终端设备根据该第六时间间隔，确定该上行HARQ RTT Timer的时间长度。例如，终端设备可以根据网络设备配置的第五时间间隔和网络设备配置的第六时间间隔，确定该上行HARQ RTT Timer的时间长度。
因此，本申请提供的传输信息的方法，网络设备通过该配置信息，为终端设备动态配置上行HARQ RTT Timer的时间长度，能够在保证数据传输时延的要求下，降低功耗。
应理解，在本发明实施例中，该第四时间间隔、该第五时间间隔或者该第六时间间隔可以由网络设备动态配置，例如，上行控制信道(DCI)信息；也可以半静态配置，例如，无线资源控制(RRC)信息；也可以通过媒体接入控制层控制元素MAC CE配置；也可以通过协议进行固定配置或指示计算规则，本申请对此不作限定。
因此，本申请提供的传输信息的方法，网络设备通过该配置信息，为终端设备动态配置HARQ RTT Timer的时间长度，能够在保证数据传输时延的要求下，降低功耗。
需要注意的是，本发明实施例下行HARQ中的第二时刻为网络设备重传该第一下行数据的最早的时刻；上行HARQ中的第五时刻为终端设备接收该第一上行数据的上行重传调度信息的最早的时刻。网络在确定配置信息的过程中，需要确定下行HARQ中的第二时刻，和/或上行HARQ中的第五时刻。该第二时刻和/或第五时刻可以是网络设备为终端设备预配置的可能的最早时刻，用于保证数据的传输时延较小。
可选地，网络设备根据该终端设备的能力信息，确定该下行HARQ中的第二时刻，或者该上行HARQ中的第五时刻。
具体而言，在灵活HARQ中，网络设备可以指定终端设备执行相关动作的时间。例如，在收到上行调度几个时间单元后发送上行数据，或者在收到下行数据几个时间单元后反馈ACK/NACK。这个时间指示，一方面需要考虑资源使用情况，另一方面也受到终端设备处理能力的限制，比如终端设备的最短的处理时间。
例如，在下行数据传输场景中，基站向终端设备指示下行调度，并在相同时间单元内向终端设备发送数据。终端设备的处理包括PDCCH盲检测和PDSCH的解调，并判断本次解调是否成功，并生成相应的ACK/NACK信号用于通知基站。基站指示终端设备在收到下行数据后反馈ACK/NACK的时间间隔，应该至少大于终端设备的处理时延。
又例如，在上行数据传输场景中，在收到上行调度后，终端设备需要按照调度要求进行数据组包和生成，这个处理时间同样是基站调度的下限。
可选地，网络设备在确定配置信息之前，该方法300还包括：获取该终端设备的能力信息。
可选地，该能力信息用于指示该终端设备处理数据的时延的信息。
图8是根据本发明实施例的终端设备的处理时延的示意性结构图。
如图8所示，时间单元为2个符号的场景中，终端设备向基站上报下行数据的处理时延为3.6个TTI，即网络设备指示终端设备可以在第n+4个时间单元反馈ACK/NACK。
可选地，该能力信息包括以下信息中的至少一项：该终端设备接收下行数据和该终端设备发送该下行数据的反馈信息的最小处理时延；该终端设备接收上行初传调度信息和该终端设备发送上行数据之间的最小处理时延；该终端设备接收上行重传调度信息和该终 端设备发送上行数据之间的最小处理时延。
可选地，在终端设备上报处理时延时，可以直接上报具体的时延值，也可以将具体的时延值根据预设表格，换算成相应的索引，并将索引进行上报。本申请对此不作限定，
例如，一种可能的表格如下：
表1终端设备处理时延预设表格
Figure PCTCN2017112935-appb-000001
其中，表中的TTI表示时间单元，应理解，表1只是示例性的，本发明实施例对表中的数值不作具体限定。例如，表1中处理时延值范围的取值可以根据实际情况而定。又例如，表1中的处理时延值范围还可以为不包含左侧边界值，包含右侧边界值等。本申请对此不作限定。
因此，本发明实施例提供的传输信息的方法，网络设备通过终端设备上报的该终端设备的能力信息，能够更快或更准确的确定该配置信息。
上面结合4至图8详细说明了网络设备确定该配置信息的实现方式，下面对网络设备向终端设备发送该配置信息的实现方式，以及终端设备根据该配置信息确定该HARQ RTT Timer的时间长度的具体实现进行说明。
如图4所示，本申请提供的传输信息的方法还包括：

应理解，在本发明实施例中，网络设备可以通过RRC信息，或者DCI信息，或者该MAC CE信息向终端设备发送该配置信息，也可以通过其它方式向终端设备发送该配置信息，例如，在协议中规定该配置信息。本发明对此不作限定。

可选地，如图6所示，该配置信息可以包括第二时间间隔和第三时间间隔，终端设备根据该第二时间间隔和第三时间间隔能够计算出下行HARQ RTT Timer的时间长度，以下称为估算长度。
应理解，终端设备根据该配置信息计算该估计长度，该配置信息可以包括第二时间间隔和第三时间间隔，也可以只包括第二时间间隔或者第三时间间隔。
例如，该配置信息只包括第二时间间隔，该第三时间间隔可以通过静态/半静态进行预配置，也可以通过协议进行规定，也可以按预定规则进行确定，例如第三时间间隔等于第二时间间隔等等。
可选地，如图6所示，该配置信息可以只包括第一时间间隔，终端设备直接将该第一时间间隔确定为下行HARQ RTT Timer的时间长度，以下称为预配长度。
又例如，如图6所示，该配置信息可以同时包括第一时间间隔、第二时间间隔和第三时间间隔。终端设备在估算长度和预配长度中，确定满足第一准则的时间间隔为该下行HARQ RTT Timer的时间长度。
可选地，该第一准则可以是终端设备在估算长度和预配长度中，选择较长的时间长度为该下行HARQ RTT Timer的时间长度，该第一准则也可以是终端设备在估算长度和预配长度中，选择较短的时间长度为该下行HARQ RTT Timer的时间长度。
应理解，终端设备根据该配置信息，可以使用估算长度，也可以使用预配长度，具体使用哪一种可以由终端设备自己计算确定，也可以由网络设备指示，也可以在协议中规定。
还应理解，本发明实施例中的第一准则可以是根据估算长度和预配长度的具体数值进行选择的准则，也可以其它准则。该第一准则可以由网络设备配置并通知给终端设备，也可以是在协议中规定。本申请对此不作限定。
还应理解，终端设备也可以通过上述方法确定下行HARQ RTT Timer的时间长度，也可以根据上述方法确定上行下行HARQ RTT Timer的时间长度，为避免重复描述，本申请在此不再赘述。
因此，本申请提供的传输信息的方法，终端设备通过网络设备发送的配置信息，能够更准确的确定HARQ RTT Timer的时间长度。
