Description

一种信道传输方法、电子设备及存储介质 技术领域
本发明涉及无线通信技术领域，尤其涉及一种信道传输方法、电子设备及存储介质。
背景技术
相关技术中，随机接入(Random Access Channel，RACH)包括：第一类随机接入和第二类随机接入。针对第一类随机接入，终端设备与网络设备之间需要执行2次信息交互，即终端设备向网络设备发送消息(Msg)A，网络设备向终端设备发送MsgB。因此，第一类随机接入也称为二步随机接入(2-steps RACH)。针对第二类随机接入，终端设备与网络设备之间需要执行4次信息交互；因此，第二类随机接入也称为四步随机接入(4-steps RACH)。
在第一类随机接入中，由于MsgA中包括Preamble和PUSCH，网络设备需要对PUSCH进行解码；因此，终端设备在什么时频位置检测承载MsgB的信道、或网络设备在什么时频位置传输承载MsgB的信道才能够提高系统的性能，目前尚无有效解决方案。
发明内容
为解决上述技术问题，本发明实施例提供一种信道传输方法、电子设备及存储介质，终端设备确定了检测承载MsgB的信道的时间窗口的起始位置，网络设备确定了传输承载MsgB的信道的时间窗口的起始位置；在所述起始位置开始传输信道或检测信道，能够降低终端设备的功耗，提高网络设备的调度性能。
第一方面，本发明实施例提供一种信道传输方法，包括：终端设备基于网络设备发送的消息确定信道检测的时间窗口的起始位置，所述起始位置位于随机接入信道(Random Access CHannel，RACH)时机或者物理上行共享信道(Physical Uplink Shared CHannel，PUSCH)时机结束后的时间延迟之后；所述时间延迟为至少两个符号，或者所述时间延迟与所述RACH时机与所述PUSCH时机的时域关系相关。
第二方面，本发明实施例提供一种信道传输方法，网络设备确定信道传输的时间窗口的起始位置，所述起始位置位于RACH时机或者PUSCH时机结束后的时间延迟之后；所述时间延迟为至少两个符号，或者所述时间延迟与所述RACH时机与所述PUSCH时 机的时域关系相关。
第三方面，本发明实施例提供一种终端设备，所述终端设备包括：第一处理单元，配置为基于网络设备发送的消息确定信道检测的时间窗口的起始位置，所述起始位置位于RACH时机或者PUSCH时机结束后的时间延迟之后；所述时间延迟为至少两个符号，或者所述时间延迟与所述RACH时机与所述PUSCH时机的时域关系相关。
第四方面，本发明实施例提供一种网络设备，所述网络设备包括：
第二处理单元，配置为确定信道传输的时间窗口的起始位置，所述起始位置位于RACH时机或者PUSCH时机结束后的时间延迟之后；所述时间延迟为至少两个符号，或者所述时间延迟与所述RACH时机与所述PUSCH时机的时域关系相关。
第五方面，本发明实施例提供一种终端设备，包括处理器和用于存储能够在处理器上运行的计算机程序的存储器，其中，所述处理器用于运行所述计算机程序时，执行上述终端设备执行的信道传输方法的步骤。
第六方面，本发明实施例提供一种网络设备，包括处理器和用于存储能够在处理器上运行的计算机程序的存储器，其中，所述处理器用于运行所述计算机程序时，执行上述终端设备执行的信道传输方法的步骤。
第七方面，本发明实施例提供一种存储介质，存储有可执行程序，所述可执行程序被处理器执行时，实现上述终端设备执行的信道传输方法。
第八方面，本发明实施例提供一种存储介质，存储有可执行程序，所述可执行程序被处理器执行时，实现上述网络设备执行的信道传输方法。
本发明实施例提供的信道传输方法，包括：终端设备基于网络设备发送的消息确定信道检测的时间窗口起始位置，或者网络设备确定信道传输的时间窗口的起始位置；所述起始位置位于RACH时机或者PUSCH时机结束后的时间延迟之后；所述时间延迟为至少两个符号，或者所述时间延迟与所述RACH时机与所述PUSCH时机的时域关系相关。一方面，由于所述时间延时为至少两个符号，不仅避免了相关技术中时间延迟为一个符号时，网络设备由于在一个符号内无法完成对Msg A的接收和解码、以及对Msg B进行编码；使得网络设备无法在Msg B的接收窗口的初期发送Msg B，只能在Msg B的接收窗口后期发送Msg B，所导致的对网络设备的调度的限制。而且避免了终端设备过早开启Msg B的接收窗口，而网络设备并不能及时的发送Msg B，造成终端设备的功耗增加。另一方面，由于所述时间延迟与所述RACH时机与所述PUSCH时机的时域关系相关，使得终端设备能够根据RACH时机与所述USCH时机的时域关系，灵活的设 定信道检测的时间窗口的起始位置，进一步提高了系统的性能。

具体实施方式
为了能够更加详尽地了解本发明实施例的特点和技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
在对本发明实施例提供的信道传输方法进行详细说明之前，先对RACH过程进行简要说明。
第二类随机接入的处理流程，如图1所示，包括如下四个步骤：
步骤S101，终端设备通过消息1(message 1，Msg1)向网络设备发送随机接入Preamble。
终端设备在选择的PRACH时域资源上发送选择的Preamble；网络设备根据Preamble能够估算上行Timing以及终端设备传输Msg3所需要的上行授权的大小。
步骤S102，网络设备检测到有终端设备发送Preamble之后，通过Msg2向终端设备发送随机接入响应(Random Access Response,RAR)消息，以告知终端设备在发送 Msg3时可以使用的上行资源信息，为终端设备分配临时的无线网络临时标识(Radio Network Tempory Identity，RNTI)，为终端设备提供time advance command等。
步骤S103，终端设备接收到RAR消息之后，在RAR消息所指定的上行资源中发送Msg3。
其中，Msg3的消息主要用于通知网络设备该RACH过程是由什么事件触发。举例来说，如果是初始随机接入事件，则在Msg3中会携带终端设备ID和establishment cause；如果是RRC重建事件，则在Msg3中会携带连接态的终端设备标识和establishment cause。如果是在RRC连接态，则Msg3中包含一个C-RNTI MAC CE。
同时，Msg3携带的ID可以是的竞争冲突在步骤S104中得到解决。
步骤S104，网络设备向终端设备发送Msg4，Msg4中包括竞争解决消息，同时为终端设备分配上行传输资源。
终端设备接收到网络设备发送的Msg4时，会检测终端设备在Msg3发送的终端设备特定临时标识是否包含在基站发送的竞争解决消息中，若包含则表明终端设备随机接入过程成功，否则认为随机过程失败，终端设备需要再次从第一步开始发起随机接入过程。
其中，发送Msg1的资源信息通过RACH资源配置获得。在Rel-15NR技术中，定义了为接入终端设备配置的RACH资源，包括256种配置。小区使用的RACH资源配置信息在系统消息中指示给接入的终端设备。RACH资源配置包含了前导码格式(preamble format)、周期、无线帧偏移、无线帧内的子帧编号、子帧内的起始符号、子帧内PRACH时隙的个数、PRACH时隙内RACH时机的个数，和RACH时机持续时间；通过RACH资源配置能够确定PRACH资源的时域信息、频域信息和码域信息。
网络设备通过系统消息指示终端设备接收RAR所需要接收的PDCCH的搜索空间的配置信息ra-SearchSpace；终端设备通过在一个RAR时间窗内的该搜索空间中检测对应Msg1的PDCCH，从而接收Msg1对应的RAR。具体的，在RAR时间窗内，承载DCI format 1-0的PDCCH通过RA-RNTI加扰，并发送给对应的发送Msg1的终端设备。其中，通过ra-SearchSpace配置的搜索空间为Type1-PDCCH common search space。RAR时间窗通过高层参数ra-ResponseWindow进行配置。RAR时间窗开始于RACH时机的最后一个符号之后的至少一个符号之后的最近的控制资源集(CORESET)的第一个符号，CORESET是由ra-SearchSpace配置信息配置的CORESET。
RAR时间窗配置信息如下所示：
ra-ResponseWindow ENUMERATED{sl1,sl2,sl4,sl8,sl10,sl20,sl40,sl80},
其中，sl80表示RAR窗口长度为80个slot。RAR时间窗的窗口最长为10ms。
RAR时间窗的示意图，如图2所示，RAR时间窗的窗口大小为10个slot，子载波间隔为15kHz。RAR时间窗开始于PRACH occasion的最后一个符号之后的至少一个符号之后的最早的control resource set中的第一个符号，该control resource set是Type1-PDCCH common search space配置的用于接收PDCCH的时频资源。
第一类随机接入的处理流程，如图3所示，包括如下两个步骤：
步骤S201，终端设备向网络设备发送MsgA。
这里，MsgA由Preamble和payload组成。可选地，Preamble与第二类随机接入中的Preamble相同，该Preamble在PRACH资源上传输；payload携带的信息与第二类随机接入中Msg3中的信息相同，比如RRC处于空闲态时的RRC信令，以及RRC处于连接态时的C-RNTI MAC CE，payload可由PUSCH传输。可以理解为，MsgA中包括了第二类随机接入中Msg1和Msg3中的内容。
步骤S202，终端设备接收网络设备发送的MsgB。
可选地，MsgB包括第二类随机接入中Msg2和Msg4的内容；MsgB需要由PDCCH和PDSCH传输。
其中，发送preamble所在的RACH时机和发送PUSCH所在的PUSCH时机之间存在对应关系，该对应关系可以是预定义或者网络设备指示的。RACH时机和PUSCH时机在时间上的先后关系，可以如图4-1所示，RACH时机在先；或者如图4-2所示，PUSCH时机在先。
在第一类随机接入中，终端设备在发送完Msg A之后，需要根据接收的Msg B的结果，确定Msg A是否被网络设备成功接收，以便决定是否进行后续的Msg A的重传。由于Msg A中增加了PUSCH，网络设备除了需要接收Msg A中的preamble，还需要接收并解码PUSCH，根据PUSCH中的内容确定Msg B的内容。按照相关技术中RAR时间窗起始位置的确定方法，网络设备有可能无法完成Msg A的接收和解码、以及对Msg B的编码；导致网络设备无法在Msg B时间窗的初期发送Msg B，而只能在Msg B时间窗的后期才能发送Msg B，限制了网络设备的调度。对于终端设备来说，Msg B时间窗开启的过早，网络设备并不能及时的发送Msg B，造成终端设备的功耗增加。
基于上述问题，本发明提供一种信道传输方法，本申请实施例的信道传输方法可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication， GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统或5G系统等。

在一些实施例中，所述时间延迟为固定值。在具体实施时，所述时间延迟可根据下述中的至少一项确定：对PUSCH的处理时间和对PUSCH的准备时间。由于不同厂商生产的网络设备的处理能力不同，因此，基于终端设备对PDSCH的处理时间和终端设备对PDSCH的准备时间，来确定对PUSCH的准备时间和对PUSCH的处理时间。
终端设备对PDSCH的处理能力，如下表1和表2所示；终端设备对PDSCH的准备能力，如下表3和表4所示；其中，μ＝0,1,2,3分别表示PDSCH或PUSCH的子载波间隔为15KHz，30KHz，60KHz，120KHz。

根据上述表1和表2中定义的PDSCH的处理时间和PUSCH的准备时间，可以用于估计网络设备对于PUSCH的处理时间；为了保证给网络设备足够的处理时间，可以 设置相对保守的固定时间，如20个符号。同样的，根据上述表3和表4中定义的PUSCH的准备时间，可以估计对于PDSCH(即对Msg B)的准备时间；同样为了保证给网络设备足够的准备时间，可以设置相对保守的固定时间，如36个符号。实际上，网络设备的处理能力比终端设备要强，各厂商的设备的处理能力也不同，可定义在RACH时机或者PUSCH时机结束后的N个符号之后的最近的CORESET的第一个符号的起始位置作为Msg B接收窗口的起始位置。N的取值要大于现有的1个符号的固定时间，以便MsgA中PUSCH的接收和解码。N的取值可以是2-M的任意取值，M可以是网络设备对于PUSCH的处理时间和Msg B的准备时间所需要的时间的最大值。举例说明，M可以是20+36＝56个符号。此时，信道检测的时间窗口的起始位置的示意图，如图7所示；N个符号的起始点是RACH时机的结束时间点或者PUSCH时机结束的时间点。
所述时间延迟为固定值时，终端设备在确定信道检测的时间窗口的起始位置之前，需要接收网络设备发送的消息，基于网络设备发送的消息，确定RACH时机或者PUSCH时机；以及基于网络设备发送的消息确定Type1-PDCCH common search space。再将RACH时机或者PUSCH时机结束后的时间延迟之后的第一个CORESET的第一个符号的起始位置作为信道检测的时间窗口的起始位置。终端设备基于所述起始位置检测MsgB。这里，通过设置固定的时间延迟，不仅能够满足网络设备对PUSCH的处理时间和对PDSCH的准备时间，而且能够降低终端设备的功耗、降低网络设备和终端设备的实现复杂度。
在另一些实施例中，所述时间延迟为可变值。在具体实施时，所述时间延迟根据PDCCH的子载波间隔或者PUSCH的子载波间隔确定；其中，所述PDCCH为在Type-1-PDCCH common search space发送的PDCCH。如上述表1至表4所示，μ＝0,1,2,3分别表示子载波间隔为15KHz，30KHz，60KHz，120KHz。对于不同的μ，可以对应不同的时间延时。例如，μ＝0,1,2,3分别对应时间延时N1，N2，N3，N4个符号。其中，N4>＝N3>＝N2>＝N1。同样，N1，N2，N3，N4的取值考虑了网络设备对于PUSCH的处理时间和Msg B的准备时间所需要的时间；可规定N1，N2，N3，N4分别的取值。一种方式是，N1，N2，N3，N4的取值直接参考现有标准中定义的终端设备的PDSCH processing capability 1中定义的μ＝0,1,2,3时的PDSCH处理时间，用于确定网络设备对于PUSCH的处理时间，或者直接作为N1，N2，N3，N4的取值。同样的，N1，N2，N3，N4的取值直接参考现有标准中定义的终端设备的PUSCH preparation time for PUSCH timing capability 1中定义的μ＝0,1,2,3时的PUSCH的准备时间，用于确定网络 设备对于PDSCH的处理时间，或者直接作为N1，N2，N3，N4的取值。
所述时间延迟为可变值时，终端设备在确定信道检测的时间窗口起始位置之前，需要接收网络设备发送的消息，基于网络设备发送的消息，确定RACH时机或者PUSCH时机；以及基于网络设备发送的消息确定PDCCH。再确定PDCCH的子载波间隔或者PUSCH的子载波间隔，基于PDCCH的子载波间隔或者PUSCH的子载波间隔确定时间延迟。最后将RACH时机或者PUSCH时机结束后的时间延迟之后的第一个CORESET的第一个符号的起始位置作为信道检测的时间窗口的起始位置。终端设备基于所述起始位置检测MsgB。这里，由于针对不同的子载波间隔，可以确定不同的时间延迟，使得时间延迟与不同的子载波间隔的设置更加匹配；当时间延迟为可变值时，能够增加时间延时配置的灵活性；如此，不仅满足了网络设备的处理时间，而且减少了终端设备接收MsgB的延时。
在又一些实施例中，所述RACH时机与所述PUSCH时机的时域关系由所述终端设备根据所述网络设备发送的消息确定，或者预先设定。其中，所述RACH时机与所述PUSCH时机的时域关系包括下述中的至少一项：所述RACH时机与所述PUSCH时机在时间上的先后关系，以及所述RACH时机与所述PUSCH时机的时间差。所述RACH时机与所述PUSCH时机在时间上的先后关系，可以是RACH时机在先，或者PUSCH时机在先。根据RACH时机和PUSCH时机在时间上的先后关系不同，用于确定信道检测的时间窗口的起始位置的时间延迟也不同。如果从RACH时机结束时间点算起，所需要的时间延时对于RACH时机和PUSCH时机在时间上的先后关系来说也是不同的。例如，当PUSCH时机在RACH时机之前，则当RACH时机结束时，网络设备已经完成了PUSCH的解调，或者已经完成的PSUCH的接收；，那么网络设备需要的处理时间就会降低，此时所述的时间延时就会变小。相反，当PUSCH时机在RACH时机之后，则当RACH时机结束时，网络设备还需要进一步完成PUSCH的接收和解调，那么网络设备需要的处理时间就会增大，此时所述的时间延时就会增大。其中，PUSCH时机在RACH时机之前时的时间延迟示意图，如图8所示；RACH时机在PUSCH时机之前时的时间延迟示意图，如图9所示。
上面描述了所述RACH时机与所述PUSCH时机在时间上的先后关系对时间延迟的影响；下面说明所述RACH时机与所述PUSCH时机的时间差对时间延迟的影响。举例来说，所述PUSCH时机在所述RACH时机之后时，所述RACH时机与所述PUSCH时机的时间差越大，所述时间延迟就越大，所述时间延迟为固定时延和所述RACH时机与 所述PUSCH时机的时间差之和；此时，所述起始位置位于RACH时机结束之后。其中，固定时延为至少一个符号。
在具体实施时，终端设备在确定信道检测的时间窗口的起始位置之前，需要接收网络设备发送的消息，基于网络设备发送的消息，确定RACH时机或者PUSCH时机；以及基于网络设备发送的消息确定Type1-PDCCH common search space、以及所述RACH时机与所述PUSCH时机的时域关系。终端设备根据所述RACH时机与所述PUSCH时机的时域关系确定时间延迟；最后将RACH时机或者PUSCH时机结束后的时间延迟之后的第一个CORESET的第一个符号的起始位置作为信道检测的时间窗口的起始位置。终端设备基于所述起始位置检测MsgB。这里，针对RACH时机与PUSCH时机的时域关系，可以确定不同的时间延时，便于更加灵活的设置时间延迟；使得时间延迟与RACH时机与PUSCH时机的时域关系更加匹配。如此，不仅满足了网络设备的处理时间，而且减少了终端设备接收MsgB的延时。
还有一些实施例中，时间延迟由网络设备通过指示信息指示给终端设备。如网络设备的生成厂商根据网络设备需要的时间延迟来配置实际的时间延迟。可选地，所述指示信息可以承载在系统消息中，如系统消息中与RACH相关的配置信息。
在具体实施时，终端设备在确定信道检测的时间窗口的起始位置之前，需要接收网络设备发送的消息，基于网络设备发送的消息，确定RACH时机或者PUSCH时机；以及基于网络设备发送的消息确定Type1-PDCCH common search space和时间延迟。将RACH时机或者PUSCH时机结束后的时间延迟之后的第一个CORESET的第一个符号的起始位置作为信道检测的时间窗口的起始位置。终端设备基于所述起始位置检测MsgB。
这里，网络设备可以灵活的设置和指示时间延迟，能够最优化的确定信道检测的时间窗口的起始位置；并且在所述起始位置之前不需要检测PDCCH，减少终端设备的功耗。
本发明实施例除了上述几种独立确定信道检测的时间窗口的起始位置的方案外，基于上述确定信道检测的时间窗口的起始位置的方案的相互组合，也能够确定信道检测的时间窗口的起始位置。
作为一个示例，在所述时间延迟为固定时间延迟的基础上，进一步根据RACH时机与PUSCH时机的时域关系计算得到时间延迟。例如，当PUSCH时机在RACH时机之后，时间延迟＝固定时间延迟N1+PUSCH时机与RACH时机之间的时间差；当PUSCH 时机在RACH时机之前，时间延时＝固定时间延迟N2。
作为另一个示例，在定义的一个与子载波间隔相关的时间延迟的基础上，进一步根据RACH时机与PUSCH时机的时域关系，计算得到所述时间延迟。例如，当PUSCH时机在RACH时机之后，时间延时＝子载波间隔对应的时间延迟N1+PUSCH时机与RACH时机之间的时间差；当PUSCH时机在RACH时机之前，时间延迟＝子载波间隔对应的时间延迟N2。
作为再一个示例，不同的子载波间隔情况下，网络设备指示不同的时间延迟。或者，对于不同的子载波间隔，网络设备指示的时间延迟的取值范围不同。
作为又一个示例，网络设备配置了RACH时机与PUSCH时机的时域关系，网络设备对应的指示不同的时间延迟。或者，对于RACH时机与PUSCH时机之间不同的时域关系，网络设备指示的时间延迟的取值范围不同。

需要说明的是，本发明实施例所述的信道传输方法可以应用于2步RACH(第一类随机接入)中承载MsgB的信道，如PDCCH。网络设备发送给终端设备的消息为系统消息，或者无线资源控制(Radio Resource Control，RRC)消息。
