技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法、装置及计算机存储介质。
背景技术
在现有的通信系统中，终端通过随机接入过程与小区建立连接并取得上行同步。基于竞争的随机接入过程包括4步(step)，这4步分别为：1、终端向基站发送前导码(Preamble)；2、基站发送针对前导码的随机接入响应；3、终端根据随机接入响应在基站分配的资源上，向基站发送第三条消息(Msg3)，并启动或重启竞争解决定时器，Msg3中携带上行数据；4、基站向终端发送竞争解决消息。若终端在竞争解决定时器运行期间未能接收到竞争解决消息，则返回步骤1继续执行。目前，基于竞争的随机接入过程步骤较多，导致较大的时延，从而不能很好的适应一些对时延比较敏感的场景。

终端中的至少一个上行配置和至少一个随机接入配置之间的对应关系可以是预配置的(例如，协议规定的)，也可以为网络设备向终端发送的。若为后者，该方法还可以包括：21)网络设备向终端发送至少一个上行配置和至少一个随机接入配置之间的对应关系；22)终端从网络设备接收至少一个上行配置和至少一个随机接入配置之间的对应关系。
其中，当终端为空闲态(IDLE mode)或激活态(INACTIVE mode)时，网络设备向终端广播至少一个上行配置和至少一个随机接入配置之间的对应关系；或者，当终端为连接态(CONNECTED mode)时，网络设备向终端发送RRC信令(例如，RRC重配置消息)，RRC信令中包括至少一个上行配置和至少一个随机接入配置之间的对应关系。
至少一个上行配置包括第一上行配置，至少一个随机接入配置包括第一随机接入 配置，第一上行配置和第一随机接入配置具有对应关系。第一上行配置为适用于当前上行数据发送的上行配置，第一随机接入配置为与第一上行配置有对应关系的随机接入配置。不同上行数据或不同通信场景下，第一上行配置的选择不同，在此不做限制。示例性地，基于表1所示的示例，第一上行配置可以为上行配置2，第一随机接入配置可以为随机接入配置2。
一种情况下，所述上行配置包括以下信息中的任意一种或多种信息：调制编码方案(modulation coding scheme，简称MCS)表指示信息、MCS指示信息、时域资源指示信息、频域资源指示信息、传输块大小(transport block size，简称TBS)指示信息、冗余版本(redundancy version，简称RV)指示信息、混合自动重传请求(hybrid automatic repeat request，简称HARQ)进程指示信息、新传或重传指示信息、子载波间隔(subcarrier spacing，简称SCS)指示信息、预编码指示信息、重复发送次数指示信息、重复发送指示信息、解调参考信号(demodulation reference signal，简称DMRS)映射类型指示信息、跳频传输指示信息、捎带信道状态信息(channel state information，简称CSI)指示信息、功率偏置指示信息、波形指示信息、小区的索引信息、带宽部分(bandwidth part，简称BWP)的索引信息。
BWP是指网络设备分配给终端的载波带宽内的部分频域资源。BWP的大小小于或等于终端的带宽能力，即终端支持的最大带宽。且BWP可以是连续的频域资源，例如，BWP可以包括连续的多个子载波，再如，BWP可以包括多个连续的物理资源块(physical resource block，简称PRB)。BWP也可以是不连续的频域资源。其中连续的频域资源，有利于降低资源分配的复杂度，不连续的频域资源有利于离散资源的利用。终端可以支持多个BWP，即网络设备可以为终端配置多个BWP，当配置多个BWP时，BWP之间可以重叠，BWP之间也可以不重叠。此外，不同BWP包括的频域资源的子载波间隔可以相同，也可以不同。
CSI可以是终端向网络设备发送的用于指示下行信道的信道质量的信息。CSI可以是根据下行参考信号获取的。CSI可以包括以下信息中的一种或多种：信道质量指示(channel quality indicator，简称CQI)，用于网络设备确定后续调度采用的调制编码方式；秩指示(rank indication，简称RI)，用于指示物理下行共享信道(physical downlink shared channel，简称PDSCH)的有效的数据层数，以及用于通知网络设备终端当前可以支持的码字数；预编码矩阵指示(precoding matrix indicator，简称PMI)，用于指示码本矩阵的索引(index)；预编码类型指示(precoding type indicator，简称PTI)，信道状态信息参考信号资源指示(channel state information reference signal resource indicator，简称CRI)，同步信号/广播信道块资源指示(synchronization signal/physical broadcast channel block resource indicator，简称SSBRI)，层1-参考信号接收功率(layer1reference signal received power，简称L1-RSRP)等。
另一种情况下，所述上行配置包括以下信息中的任意一种或多种信息：MCS表指示信息、MCS指示信息、时域资源指示信息、频域资源指示信息、TBS指示信息。
本申请实施例中提供了上行配置中可能包含的多种信息，增加了上行配置的灵活性，以适应不同的应用场景。
随机接入配置包括以下信息中的任意一种或多种信息：时域资源指示信息、频域 资源指示信息、至少一个前导码索引、根(root)序列指示信息、最大传输次数指示信息、接收窗口长度指示信息、前导码功率攀升步长指示信息、SCS指示信息、退避指示(Backoff indication)的缩放因子指示信息、重复发送次数(repetition)指示信息。
其中，上行配置以及随机接入配置中可能包含的各个信息的含义可参见下文。
202、终端根据第一上行配置和第一随机接入配置的对应关系利用第一上行配置向网络设备发送上行数据并利用第一随机接入配置向网络设备发送前导码。
可选地，上行数据包括终端的控制面数据和终端的用户面数据中的一种或多种。该上行数据可以携带终端的标识，用于网络设备识别该上行数据所属的终端。前导码可用于与网络设备进行上行同步。上行数据和前导码可以包含在同一条消息中，例如，都包含在第一消息(Msg1)中，也可以包含在不同的消息中。
可选地，步骤202在具体实现时包括：31)终端确定上行数据对应的第一上行配置；32)终端根据第一上行配置和第一随机接入配置的对应关系确定第一上行配置对应的第一随机接入配置；33)终端利用第一上行配置向网络设备发送上行数据，且利用第一随机接入配置向网络设备发送前导码。
一种情况下，步骤31)在具体实现时可以包括：所述终端根据信道状态信息或待发送数据的数据量或待发送数据的业务信息确定所述上行数据对应的所述第一上行配置。
其中，上行数据可以为待发送数据的部分或全部数据。
其中，信道状态信息可以为下行路损信息或参考信号接收功率(reference signal received power，简称RSRP)。示例性地，若下行路损小于第一数值，终端选择上行配置2(即第一上行配置为上行配置2)发送上行数据，并根据上行配置2对应的随机接入配置2向网络设备发送前导码；否则，终端选择上行配置1(即第一上行配置为上行配置1)发送上行数据，并根据上行配置1对应的随机接入配置1向网络设备发送前导码。第一数值的计算方式可以为：PCMAX-前导码的目标接收功率(preamble received target power)-上行数据与前导码的功率偏置(data-deltapreamble)-上行配置关联的功率偏置(messagePowerOffset)。其中，PCMAX是指终端发起随机接入的小区的最大发送功率(of the serving cell performing the random access procedure)。
终端计算的待发送数据的数据量包括上行待发送数据的数据量和媒体接入控制(medium access control，简称MAC)字头的字节数，还可以包括MAC控制元素(MAC control elements，简称MAC CE)的字节数。不同的待发送数据的数据量可以对应不同的上行配置，示例性地，若有上行配置1和上行配置2，当待发送数据的数据量超过预设门限，终端选择上行配置2(即第一上行配置为上行配置2)发送上行数据，并根据上行配置2对应的随机接入配置2向网络设备发送前导码；否则，终端选择上行配置1(即第一上行配置为上行配置1)发送上行数据，并根据上行配置1对应的随机接入配置1向网络设备发送前导码。示例性地，若上行配置1关联的MCS1，最多能传输600字节(bytes)数据，上行配置2关联的MCS2，最多能传输1000bytes数据，则预设门限可以设置为600bytes。
待发送数据的业务信息可以为待发送数据的服务质量(quality of service，简称Qos)需求、待发送数据所属的逻辑信道、待发送数据的可靠性要求或待发送数据的时延要 求。不同的业务信息可以和不同的上行配置对应。该情况下，终端可以根据上行数据对应的业务信息确定上行数据对应的上行配置。业务信息和上行配置的对应关系可以由网络设备配置。
另一种情况下，步骤31)在具体实现时可以包括：终端根据信道状态信息、待发送数据的数据量和待发送数据的业务信息中的多个信息确定上行数据对应的上行配置。
示例性地，当信道状态信息为下行路损信息时，终端还可以根据待发送数据的数据量和下行路损信息确定所述上行数据对应的上行配置。示例性地，若上行配置1关联的MCS1，最多能传输600bytes数据，上行配置2关联的MCS2，最多能传输1000bytes数据。如果待发送数据的数据量超过600bytes、且下行路损小于第一数值，终端选择上行配置2(即第一上行配置为上行配置2)发送上行数据，并根据上行配置2对应的随机接入配置2向网络设备发送前导码；否则，终端选择上行配置1(即第一上行配置为上行配置1)发送上行数据，并根据上行配置1对应的随机接入配置1向网络设备发送前导码。第一数值的计算方式参见上文，在此不再赘述。
本申请实施例中提供了多种确定第一上行配置的方式，以适应不同的应用场景。
步骤202或步骤33)中，终端可以利用第一上行配置中包含的信息对上行数据作第一处理并向网络设备发送上行数据，第一上行配置中包含的信息不同时，第一处理也不同，具体可参见下文。
前导码可以在物理随机接入信道(physical random access channel，简称PRACH)上发送，上行数据可以在物理上行共享信道(physical uplink shared channel，简称PUSCH)上发送。
其中，参见图3，承载上行数据的时频资源和承载前导码的时频资源之间的位置关系可以为情况1至情况3中的任意一种情况：
情况1、承载上行数据的时域资源和承载前导码的时域资源连续，承载上行数据的频域资源和承载前导码的频域资源可以相同也可以不同。
情况2、承载上行数据的时域资源和承载前导码的时域资源不连续，承载上行数据的频域资源和承载前导码的频域资源可以相同也可以不同。
情况3、承载上行数据的时域资源和承载前导码的时域资源在相同时隙(slot)，承载上行数据的频域资源和承载前导码的频域资源不同。
203、网络设备从终端接收前导码，并根据第一上行配置和第一随机接入配置的对应关系利用第一随机接入配置对应的第一上行配置对上行数据进行处理(记为第二处理)。
步骤203在具体实现时可以包括：41)网络设备从终端接收前导码；42)网络设备根据前导码确定第一随机接入配置；43)网络设备根据第一上行配置和第一随机接入配置的对应关系确定第一随机接入配置对应的第一上行配置；44)网络设备根据第一上行配置对上行数据进行第二处理。

步骤203或步骤44)中，网络设备可以利用第一上行配置中包含的信息对上行数据作第二处理，第一上行配置中包含的信息不同时，第二处理也不同，具体可参见下文。
在步骤203之后，该方法还可以包括：51)网络设备向终端发送上行数据的响应消息，响应消息包括第一指示信息和/或第二指示信息，第一指示信息用于指示响应消息是否包括上行授权域，第二指示信息用于指示响应消息是否包括竞争解决域；52)终端从网络设备接收上行数据的响应消息。当上行数据和前导码都包含在第一消息中时，该响应消息也可以称为第一消息的响应消息。
第一指示信息和第二指示信息可以位于响应消息中的预留比特中或响应消息的MAC字头中的预留比特中。
其中，当第一指示信息用于指示响应消息包括上行授权域时，响应消息中可以包括上行授权(UL grant)，终端可以在响应消息中获取上行授权(UL grant)。当第二指示信息指示响应消息中包括竞争解决域时，响应消息中可以包括竞争解决信息，终端可以在响应消息中获取竞争解决信息，竞争解决信息用于通知终端随机接入完成。竞争解决信息可以为从终端接收的信息的部分内容，例如，可以包括终端的标识信息。或者，可以采用终端标识解扰的方式来确定竞争解决。例如响应消息为下行控制信息(downlink control information，简称DCI)时，网络设备使用终端标识，例如小区无线网络临时标识(cell radio network temporary identifier，简称C-RNTI)对DCI的循环冗余校验(cyclic redundancy check，简称CRC)信息进行加扰；终端对CRC进行解扰，然后使用这个解扰之后的CRC信息，去检验DCI，检验无传输错误，则该DCI是发送给该终端的，竞争解决成功。再如，响应消息为MAC CE时，可以对指示MAC CE资源位置的DCI的CRC信息进行加扰。该终端的标识信息可以是网络设备发送给终端的，可以由接入网设备分配也可以由核心网设备分配；或者可以是终端生成的，例如终端生成的随机值。
可选地，响应消息还包括：定时提前命令(timing advance command)和/或随机接入前导标识(random access preamble index，简称RAPID)。
可选地，响应消息可以承载于DCI或MAC CE中。
可选地，响应消息还可以包括HARQ反馈，该HARQ反馈用于指示上行数据是否被网络设备成功解码，响应消息的HARQ反馈的时频资源位置可以通过随机接入配置关联的时域资源或频域资源或Preamble资源映射出一个位置，用于接收响应消息中的HARQ反馈。
可选地，该方法还包括：61)终端向网络设备发送上行数据对应的上行控制信息；62)网络设备从终端接收上行数据对应的上行控制信息。该情况下，步骤203在具体实现时可以包括：网络设备从终端接收前导码，网络设备根据第一上行配置和第一随机接入配置的对应关系利用上行控制信息和第一随机接入配置对应的第一上行配置对上行数据进行第二处理。
其中，上行控制信息包括以下信息中的任意一种或多种信息：RV指示信息、HARQ进程指示信息、新传或重传指示信息、SCS指示信息、预编码指示信息、重复发送次数指示信息、重复发送指示信息、DMRS映射类型指示信息、跳频传输指示信息、捎 带CSI指示信息、功率偏置指示信息、波形指示信息、新传时所处的小区的索引信息、新传时所处的BWP的索引信息、新传时HARQ进程的信息。
该情况下，上行配置可以包括MCS表指示信息、MCS指示信息、时域资源指示信息、频域资源指示信息和TBS指示信息中的任意一种或多种信息。
本申请实施例中将用于指示发送上行数据的一种或多种信息(或称为参数)包含在上行数据对应的上行控制信息中，从而使得终端更加灵活的发送上行数据。
网络设备可以利用上行控制信息中包含的信息对上行数据作第二处理，上行控制信息中包含的信息不同时，第二处理也不同，具体可参见下文。
该情况下，上行配置既可以指示发送上行数据的参数，也可以指示发送上行控制信息的参数。此时，上行配置关联的时域资源指示信息可以包括用于传输上行数据和/或上行控制信息的时域资源指示信息，频域资源指示信息可以包括用于传输上行数据和/或上行控制信息的频域资源指示信息。当然，发送上行数据的参数和发送上行控制信息的参数也可以包含在不同的上行配置中，本申请实施例对此不作具体限定，本文中以上行数据和上行控制信息对应同一上行配置为例进行说明。
其中，上行控制信息、上行数据和前导码可以包含在同一条消息中，例如，都包含在第一消息(Msg1)中，也可以包含在不同的消息中。
其中，承载上行数据的时频资源、承载上行控制信息的时频资源和承载前导码的时频资源之间的位置关系可以为情况4至情况6中的任意一种情况：
情况4、承载上行数据的时域资源、承载上行控制信息的时域资源和承载前导码的时域资源连续，承载上行数据的频域资源、承载上行控制信息的频域资源和承载前导码的频域资源中的任意两个资源可以相同也可以不同。
情况5、承载上行数据的时域资源、承载上行控制信息的时域资源和承载前导码的时域资源不连续，承载上行数据的频域资源、承载上行控制信息的频域资源和承载前导码的频域资源中的任意两个资源可以相同也可以不同。
情况6、承载上行数据的时域资源、承载上行控制信息的时域资源和承载前导码的时域资源在相同时隙(slot)，承载上行数据的频域资源、承载上行控制信息的频域资源和承载前导码的频域资源中的任意两个资源不同。
本申请实施例提供的方法，由于终端和网络设备上均配置有上行配置和随机接入配置之间的对应关系，因此，终端可以在随机接入过程中，发送上行数据，减少基于竞争的随机接入过程的步骤，降低随机接入过程的时延，从而提高对时延敏感场景的适应能力。并且，终端通过2步就可以实现基于竞争的随机接入，简化终端的随机接入流程，降低终端与网络设备之间的信令开销。同时，终端针对不同的TBS的上行数据可以选择不同的上行配置进行处理，可以支持多种TBS的TB的传输。
为了使得本申请实施例中的方案更加的清楚，以下对本申请实施例中的上行配置和上行控制信息中可能包含的各个信息的含义以及各个信息对应的第一处理和第二处理作具体说明。其中，一个信息对应的第一处理是指终端使用该信息时的处理动作，一个信息对应的第二处理是指网络设备使用该信息时的处理动作。

实施例2
参见图5，该方法包括：
501、终端从网络设备接收至少一个随机接入配置和至少一个上行配置。
其中，至少一个随机接入配置和至少一个上行配置存在对应关系。关于该对应关系的相关描述可参见上文。
