具体地，该终端设备可以对不同的信道优先级采用不同的信道编码方式。例如，如果该第一信道的信道优先级为0，则该终端设备可以确定该第一信道的信道编码方式为LDPC；如果该第一信道的信道优先级为1，则该 终端设备确定该第一信道的信道编码方式为Polar码。这样，通过针对不同的信道优先级采用不同的信道编码方式，以得到不同的传输时延和传输可靠性，从而满足不同业务类型的需求。
作为另一个可选实施例，该第一信道的传输方式可以包括该第一信道的传输时长，即该第一信道占用的时域资源的长度，可选地，该时域资源的长度可以指时域资源包含的OFDM符号数，但本发明实施例不限于此。例如，该第一信道为数据信道，当该第一信道的信道优先级为0时，终端设备可以采用时隙来传输该第一信道；当该第一信道的信道优先级为1时，终端设备可以采用迷你时隙来传输该第一信道，其中迷你时隙的长度可以由网络侧配置。在本发明实施例中，可选地，对于传输时延要求较高的业务类型可以配置较高的信道优先级，并且可以采用较短的时域资源来传输，而传输时延要求较低的业务类型可以配置较低的信道优先级，并且可以采用较长的时域资源来传输，从而满足不同的需求。

作为另一个可选实施例，该第一信道的传输方式可以包括该第一信道的MCS。可选地，在本发明实施例中，对于同一指示信息，不用的信道优先级可以对应不同的调制编码方式，也就是说，如果MCS指示信息指示MCS＝k，则在不同的信道优先级下，MCS＝k对应的调制编码方式可以不同。此时，如果该第一信道为数据信道，则该终端设备还可以根据该第一信道的信道优先级，确定用于调度该第一信道的DCI中的MCS指示信息所对应的调制编码方式。
作为一个可选例子，如果该第一信道的信道优先级为0，则MCS指示信息可以对应固定的MCS，可以用于mMTC业务；如果该第一信道的信道优先级为1，则MCS指示信息可以对应调制方式为正交相移键控(Quadrature  Phase Shift Keyin，QPSK)或16正交振幅调制(Quadrature Amplitude Modulation，QAM)的MCS，可以用于URLLC业务以保证可靠性；如果该第一信道的信道优先级为2，则MCS指示信息可以对应调制方式为QPSK、16QAM或64QAM的MCS，可以用于eMBB业务以保证传输效率。例如，MCS指示信息为101，如果该第一信道的信道优先级0，则该MCS指示信息指示的调制方式为QPSK；如果该第一信道的信道优先级为1，则该MCS指示信息指示的调制方式为16QAM；如果该第一信道的信道优先级为2，则该MCS指示信息指示的调制方式为64QAM，但本发明实施例不限于此。
作为另一个可选实施例，该第一信道的传输方式可以包括该第一信道的重传方式，例如是否对该第一信道进行连续多次重复传输和/或重复传输的次数等等。作为一个可选例子，该第一信道为数据信道，如果该第一信道的信道优先级为0，则终端设备可以连续多次重复地传输该第一信道，其中，不同传输对应的冗余版本可以不同；如果该第一信道的信道优先级为1，则终端设备可以仅传输一次该第一信道。这样，对于可靠性要求较高的业务，可以通过多次重复传输的方式来保证传输的可靠性。

作为另一个可选实施例，该第一信道的传输方式可以包括该第一信道的循环前缀(Cyclic Prefix，CP)类型，例如普通CP或扩展CP。例如，该第一信道的信道优先级较低时，可以采用普通CP；该第一信道的信道优先级较高时，可以采用扩展CP，但本发明实施例不限于此。
作为另一个可选实施例，如果该第一信道具体为可以周期性传输的信道，则该第一信道的传输方式可以包括该第一信道的传输周期。例如，如果该第一信道的信道优先级为0，则该第一信道可以具有较短的传输周期；如果该第一信道的信道优先级为1，则该第一信道可以具有较长的传输周期， 但本发明实施例不限于此。
作为另一个可选实施例，如果该第一信道具体为数据信道，则该第一信道的传输方式可以包括该第一信道的传输定时。可选地，该第一信道的传输定时可以包括该第一信道与用于调度该第一信道的DCI之间的时间间隔，即该DCI所占用的时域资源与该第一信道占用的时域资源之间间隔的时域资源单元的数量；或者，该第一信道的传输定时也可以包括该第一信道与对应的ACK/NACK之间的HARQ时序，即该第一信道占用的时域资源与对应的ACK/NACK反馈占用的时域资源之间间隔的时域资源单元数量，其中，这里的该时域资源单元可以为时隙、子帧、迷你时隙或OFDM符号，本发明实施例对此不做限定。
作为另一个可选实施例，如果该第一信道具体为数据信道，则该第一信道的传输方式可以包括该第一信道的HARQ合并方式，例如软合并(Chase Combine,CC)或增量冗余(Incremental Redundancy,IR)，等等，本发明实施例对此不做限定。
作为另一个可选实施例，如果该第一信道具体为数据信道，则该第一信道的传输方式可以包括该第一信道的解调参考信号(Demodulation Reference Signal，DMRS)图样。可选地，可以预先定义或配置多个DMRS图样，不同的信道优先级的信道的传输可以采用不同的DMRS图样，以达到不同的信道估计性能。其中，不同的DMRS图样可以具有不同的导频RE密度，其中，该导频RE可以用于承载该DMRS。可选地，对于可靠性要求较高的业务类型，可以通过配置较高的信道优先级使用具有较高的导频RE密度的DMRS图样；对于传输效率要求较高的业务类型，可以通过配置较低的信道优先级使用具有较低的RE密度的DMRS图样，来降低导频开销，从而满足不同业务类型的要求。
作为另一个可选实施例，如果该第一信道具体为上行数据信道，则该第一信道的传输方式可以包括该第一信道的发射功率。可选地，如果该终端设备需要同时向网络设备发送该第一信道和第二信道，并且该第一信道与第二信到的当前发射功率之和大于该终端设备的最大发射功率，则该终端设备可以根据该第一信道的信道优先级，确定该第一信道的目标发射功率，并采用该目标发射功率发射该第一信道，其中，该第一信道的目标发射功率可以小于或等于该第一信道的当前发射功率。可选地，该第一信道的当前发射功率 可以是该终端设备根据约定上行功率控制过程确定的。作为一个可选例子，当该第一信道与终端设备需要同时发送的其他上行信道的发射功率之和大于该终端设备的最大发射功率时，该终端设备可以通过比较该第一信道与该其他上行信道的信道优先级或者比较该第一信道的信道优先级与优先级阈值，来确定是否降低该第一信道的发射功率。例如，如果该第一信道的信道优先级较低，则该终端设备可以降低该第一信道的发射功率。其中，可选地，该第一信道的发射功率可以降低到0，此时，终端设备可以不传输该第一信道，但本发明实施例不限于此。可选地，如果该第一信道的信道优先级较高，则该终端设备可以不降低该第一信道的发射功率，而是仍然采用当前的发射功率。这样，在终端设备的发射功率受限的情况下，可以优先保证高优先级的数据或者业务的传输性能，从而满足高优先级数据和业务的需求。
可选地，该终端设备还可以根据该第一信道的信道优先级，确定该第一信道的最大允许发射功率或者功率提升(power boosting)值，其中，该第一信道的功率提升值可以用于该终端设备确定该第一信道的发射功率。这样，可以通过提高发射功率来优先保证高优先级的数据或者业务的传输性能，从而满足高优先级数据和业务的需求。
作为另一个可选实施例，如果该第一信道具体为上行信道，则该第一信道的传输方式可以包括该第一信道的资源冲突处理方式，即该第一信道的传输与其他信道传输发生资源冲突时的处理方式。这里的资源冲突可以指用于传输该第一信道的物理资源与用于传输其他信道的物理资源出现重叠，也可以指该第一信道与其他信道采用了不同的传输方式(例如采用不同的多址方式或子载波间隔)，且需要在相同的时域资源或频域资源传输，但终端设备的能力不支持这种传输机制，本发明实施例对此不做限定。
可选地，当该第一信道的物理资源与其它信道(例如第三信道)的物理资源冲突时，可以根据该第一信道的信道优先级，确定是否在冲突的该物理资源上传输该第一信道。
可选地，该终端设备可以通过比较该第一信道和与其冲突的其它信道(即第三信道)的信道优先级，确定是否在冲突的该物理资源上传输该第一信道。具体地，如果该第一信道的信道优先级不低于与其存在物理资源冲突的其他信道，终端设备可以在冲突的物理资源上优先传输该第一信道；否则，该终端设备可以在冲突的物理资源上丢弃该第一信道携带的信息，或者对该 第一信道进行速率匹配。这样，可以在出现资源冲突时优先传输对时延、可靠性要求较高的业务，从而满足相应需求。例如，该第一信道为物理上行控制信道(Physical Uplink Control Channel，PUCCH)，当该第一信道与其他PUCCH发生资源冲突时，可以按照各个信道的信道优先级作为信息丢弃的原则，优先传输信道优先级较高的上行控制信道中携带的控制信息，对于无法承载的信道优先级较低的上行控制信道中携带的控制信息可以丢弃，从而可以保证高优先级的控制信道传输。
可选地，该终端设备也可以通过比较该第一信道的信道优先级与优先级阈值，确定是否在冲突的该物理资源上传输该第一信道。例如，如果该第一信道的信道优先级高于该优先级阈值，则该终端设备可以确定在该冲突的物理资源上传输该第一信道；否则，该终端设备可以丢弃该第一信道承载的信息或对该第一信道进行速率匹配，本发明实施例不限于此。
作为另一个可选实施例，如果该第一信道具体为用于承载UCI的上行数据信道，则该第一信道的传输方式可以包括该第一信道中包含的UCI的传输方式，例如，UCI在该第一信道中的重复传输次数、UCI在该第一信道中占用的资源单元(Resource Element，RE)、和/或UCI的信道编码方式，等等，本发明实施例对此不做限定。
作为另一个可选实施例，如果该第一信道具体为下行信道，则该第一信道的传输方式可以包括该第一信道的假定复用方式，该终端设备可以采用该假定复用方式进行信号检测和/或信道估计，其中，该假定复用方式可以包括单用户多输入多输出(Single User Multiple Input Multiple Output，SU-MIMO)或多用户多输入多输出(Multiple User Multiple Input Multiple Output，MU-MIMO)等等，本发明实施例对此不做限定。例如，该第一信道为下行数据信道，如果该第一信道的信道优先级为0，则该终端设备可以假设该数据信道采用SU-MIMO，该第一信道的DMRS资源上不存在其他DMRS端口；如果该第一信道的信道优先级大于0，终端设备可以假设该第一信道的DMRS资源上可能存在其他复用的DMRS端口。这样，终端设备可以基于不同的假定复用方式采用不同的检测算法，从而提高检测性能。
作为另一个可选实施例，如果该第一信道具体为下行信道，则该第一信道的传输方式可以包括该第一信道译码失败的存储方式，即终端设备未成功译码该第一信道时对该第一信道承载信息的存储方式。具体地，如果当前软 缓存(soft buffer)已不足存储该第一信道承载的信息时，终端设备可以根据该第一信道的信道优先级，确定是否需要优先存储该第一信道承载的信息，其中，可选地，当该第一信道的信道优先级较低时，该终端设备可以丢弃该第一信道承载的信息，但本发明实施例不限于此。
作为另一个可选实施例，如果该第一信道具体为下行数据信道，则该方法200还可以包括：该终端设备根据该第一信道的信道优先级，确定该第一信道对应的ACK/NACK反馈的传输方式和传输优先级中的至少一种。
可选地，该反馈信息的传输方式可以包括是否进行ACK/NACK捆绑(bundling)，是否进行重复传输，等等，本发明实施例对此不做限定。可选地，当该第一信道的ACK/NACK反馈与其他数据信道的ACK/NACK反馈冲突时，该终端设备可以根据该第一信道的信道优先级，确定该第一信道对应的ACK/NACK的传输优先级，并据此确定是否需要传输该第一信道的ACK/NACK。具体地，该终端设备可以比较该第一信道的信道优先级和其它数据信道的信道优先级，或者比较该第一信道的信道优先级和优先级阈值，确定是否传输该第一信道的ACK/NACK。例如，当该第一信道的信道优先级较高时，可以优先丢弃信道优先级较低的数据信道对应的ACK/NACK，这样可以优先保证QoS较高的数据的ACK/NACK的传输，但本发明实施例不限于此。
应理解，在本发明实施例中，该第一信道的传输方式可以包括上述例子中的一种或多种，本发明实施例对此不做限定。
S250，终端设备和网络设备采用确定的该传输方式进行该第一信道的传输。
具体地，如果该第一信道为上行信道，则该终端设备可以采用确定的该传输方式发送该第一信道，相应地，该网络设备可以采用确定的该传输方式接收该第一信道。如果该第一信道为下行信道，则该网络设备可以采用确定的该传输方式发送该第一信道，相应地，该终端设备可以采用确定的该传输方式接收该第一信道。

此外，在本发明实施例中，终端设备可以知道当前待传输的信道的信道优先级，从而采用对应的物理层传输参数进行传输，从而尽量满足信道优先级对应业务的时延、可靠性、吞吐量等需求。
应理解，上述实施例均以该网络设备向该终端设备发送指示信息来告知第一信道的信道优先级，可选地，该终端设备还可以通过其它方式确定该第一信道的信道优先级，本发明实施例对此不做限定。
还应理解，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本发明实施例的实施过程构成任何限定。
