Description

一种信道处理方法、终端设备及存储介质 技术领域
本申请涉及无线通信技术领域，尤其涉及一种信道处理方法、终端设备及存储介质。
背景技术
相关技术中，在有至少两个下行信道在一定的时间间隔内传输的情况下，终端设备如何接收和/或解调两个下行信道，才能提高下行信道的传输性能，目前尚无有效解决方案。
发明内容
为解决上述技术问题，本申请实施例提供一种信道处理方法、终端设备及存储介质，在有至少两个下行信道在一定的时间间隔内传输的情况下，能够提高下行信道的传输性能。
第一方面，本申请实施例提供一种信道处理方法，包括：终端设备基于第一下行信道与第二下行信道的信道优先级信息，确定不接收和/或不解调所述第一下行信道和所述第二下行信道中的一个下行信道；

具体实施方式
为了能够更加详尽地了解本申请实施例的特点和技术内容，下面结合附图对本申请实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本申请实施例。
在对本申请实施例提供的信道处理方法进行详细说明之前，先对超高 可靠低时延通信(Ultra-Reliable Low Latency Communications，URLLC)业务进行简要说明。
新无线(New Radio，NR)支持多种类型业务，包括：增强移动宽带(eMBB，enhanced Mobile Broadband)、URLLC等。其中，eMBB业务的特征是数据量大、传输速率高，通常采用较大量的物理资源进行传输，对时延不敏感。URLLC业务的特征是数据包的产生具有突发性和随机性，对时延要求高。支持URLLC业务传输的终端设备，通常需要支持UE处理能力2，才能满足URLLC业务的时延需求。
为了保证URLLC业务的性能需求，目前3GPP讨论中考虑支持物理层可识别当前传输的PDSCH/PUSCH所承载的业务类型或业务优先级。当不同优先级的物理信道所占用的资源冲突时，优先保证高优先级的物理信道所承载的信息被传输。具体的，保证URLLC业务对应信息被优先传输。其中，确定物理信道优先级的方法可以包括：
1)通过调度物理信道所使用的DCI格式确定对应物理信道的优先级。
2)通过调度物理信道所使用的DCI采用的无线网络临时标识(Radio Network Tempory Identity，RNTI)确定对应物理信道的优先级。
3)通过调度物理信道所使用的DCI中包括的显示信息域确定对应物理信道的优先级。
4)通过传输调度物理信道所使用的DCI的资源，如控制资源集合(Control-resource set，CORESET)或搜索空间，确定对应物理信道的优先级。
再对于物理下行共享信道(Physical Downlink Shared CHannel，PDSCH)处理时延进行简要说明。
在NR Rel-15系统中，针对PDSCH处理时延，终端设备(User Equipment，UE)在接收到下行控制信息(Downlink Control Information，DCI)格式1_0或DCI 1_1的调度后，终端设备会在对应的时隙接收PDSCH，并向网络设备发送确认/不确认(ACK/NACK)反馈信息。其中，终端设备开始发送ACK/NACK反馈信息的时间不早于ACK/NACK反馈信息对应的PDSCH占用的一个时域符号结束位置之后的T proc,1＝(N 1+d 1,1)(2048+144)·κ2 -μ·T Cms。如果不满足该时间要求，终端设备不发送ACK/NACK反馈信息。其中，N1根据终端设备处理能力有不同的取值。NR Rel-15支持两种UE处理能力，分别为UE处理能力1和UE处理能力2，UE处理能力1对应的N1取值如表1所示，UE处理能力2对应的N1取值如表2所示。在上行传输和/ 或下行传输采用不同的子载波间隔时，N1的取值基于μ得到；其中μ为(μ PDCCH,μ PDSCH,μ UL)中使得T proc,1最大的一个取值，μ PDCCH对应调度PDSCH的PDCCH所使用的载波间隔，μ PDSCH对应PDSCH所使用的子载波间隔，μ UL对应传输ACK/NACK反馈信息所使用的子载波间隔。
针对采用UE处理能力2且μ PDSCH＝1(对应子载波间隔为30kHz)的情况，若调度的目标PDSCH占用的频域资源块数量超过136个时，则终端设备回退为UE处理能力1。终端设备可以跳过解调(skip decoding)所述目标PDSCH起始符号之前10个时域符号之内使用UE处理能力2接收的其他PDSCH。

Figure PCTCN2019101166-appb-000002
表2
针对采用UE处理能力2且μ PDSCH＝1(对应子载波间隔为30kHz)的情况，若调度的目标PDSCH占用的频域资源块数量超过136个时，则终端设备回退为UE处理能力1。终端设备可以跳过解调(skip decoding)所述目标PDSCH起始符号之前10个时域符号之内使用UE处理能力2接收的其他PDSCH。举例来说，在特定时间间隔内传输至少两个下行信道的示意图，如图1所示，在特定的时间间隔内传输三个下行信道，分别是PDSCH0、PDSCH1和PDSCH2，以特定的时间间隔为10个时域符号为例，在采用 30KHz的子载波间隔传输PDSCH时，当一个承载eMBB业务对应的数据包的PDSCH2被调度，且PDSCH2占用的资源块(Resourc Block，RB)个数大于136个，则终端设备将不对PDSCH2之前的10个时域符号内采用UE处理能力2接收的PDSCH(PDSCH1和PDSCH0)解码。若PDSCH2之前的10个时域符号内的PDSCH承载的是URLLC业务对应的数据，则会影响URLLC业务的传输性能。
基于上述问题，本申请提供一种信道处理方法，本申请实施例的信道处理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)系统、先进的长期演进(advanced long term evolution，LTE-A)系统、新无线(new radio，NR)系统、NR系统的演进系统、非授权频段上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、非授权频段上的NR(NR-based access to unlicensed spectrum，NR-U)系统、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、无线局域网(wireless local area networks，WLAN)、无线保真(wireless fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(device to device，D2D)通信，机器到机器(machine to machine，M2M)通信，机器类型通信(machine type communication，MTC)，以及车辆间(vehicle to vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。

通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(device to device，D2D)通信，机器到机器(machine to machine，M2M)通信，机器类型通信(machine type communication，MTC)，以及车辆间(vehicle to vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。

针对终端设备确定下行信道对应的终端设备处理能力的实现方式至少包括下述方式：
在一些实施例中，终端设备根据下行信道的优先级信息确定所述下行信道对应的终端设备处理能力；如高优先级的下行信道对应的终端设备处理能力级别，高于低优先级的下行信道对应的终端设备处理能力级别；所述终端设备在高级别的终端设备处理能力下的物理信道处理时间小于在低级别的终端设备处理能力下的物理信道处理时间。举例来说，第一下行信道的优先级高于第二下行信道的优先级，则终端设备确定第一下行信道对应第二终端设备处理能力，第二下行信道对应第一终端设备处理能力。其中，终端设备在第二终端设备处理能力下的物理信道处理时间小于在低级别的终端设备处理能力下的物理信道处理时间；即第二终端设备处理能力级别高于第一终端设备处理能力级别。
在另一些实施例中，终端设备根据下行信道的传输参数确定所述下行信道对应的终端设备处理能力。其中，所述传输参数可以包括下述中的至少一种：子载波间隔、时域长度、调制编码等级、传输块大小、物理资源块数量、和预编码方式。举例来说，在所述传输参数中的：子载波间隔、时域长度、调制编码等级、传输块大小、和物理资源块数量的值越大的情况下，所述终端设备确定所述下行信道对应高级别的终端设备处理能力。在所述传输参数包括预编码方式时，可以根据预设的预编码方式与终端设备处理能力的对应关系，确定下行信道对应的终端设备处理能力。需要说明的是，上述仅针对传输参数包括的内容进行示例，并不对传输参数包括的内容进行限定；任何能够表征信道传输性能的参数均在本申请传输参数的范围之内。
在又一些实施例中，若终端设备根据优先级信息确定基于第二终端设备处理能力接收和/或解调下行信道的情况下，若所述下行信道中的传输参 数满足第一条件，则所述终端设备确定基于所述第一终端设备处理能力接收和/或解调所述下行信道。可选地，所述第一条件包括：子载波间隔为30KHz和下行信道占用的RB大于136个。举例来说，网络设备配置终端在某特定载波上基于第二终端设备处理能力接收和/或解调下行信道。若网络设备当前调度的PDSCH采用30kHz子载波，且调度带宽超过136RB，则终端设备基于第一终端设备处理能力接收和/或解调该PDSCH；否则采用第二终端设备处理能力接收和/或解调该PDSCH。若终端设备已经确定基于第二终端设备处理能力接收和/或解调下行信道，但是，终端设备判断传输参数满足第一条件，则终端设备进行能力回退，即终端设备由采用高级别的第二终端设备处理能力回退为采用低级别的第一终端设备处理能力进行信道处理。
还有一些实施例中，若终端设备基于传输参数确定所述第二终端设备处理能力接收和/或解调下行信道的情况下，若所述下行信道的优先级信息对应所述第一终端设备处理能力，则所述终端设备确定基于所述第一终端设备处理能力接收和/或解调下行信道。
需要说明的是，本申请实施例中，所述信道的优先级信息至少包括下行信道所承载的业务的优先级信息。举例来说，第一PDSCH承载URLLC业务对应的数据，第二PDSCH承载eMBB业务对应的数据，URLLC业务的优先级高于eMBB业务的优先级，则第一PDSCH的优先级高于第二PDSCH的优先级。或者，下行信道自身存在优先级；举例来说，第一PDSCH自身的优先级高于第二PDSCH自身的优先级，则无论第一PDSCH和第二PDSCH承载的数据类型是什么，第一PDSCH的优先级都高于第二PDSCH的优先级。
下面针对不同的场景，对第一下行信道与第二下行信道之间的时间间隔小于或等于时间间隔阈值的情况下，终端设备如何接收和/或解调两个下行信道进行举例说明。
在一些场景下，终端设备在目标时域资源上基于第二终端设备处理能力接收并解调第一PDSCH，第一PDSCH的信道优先级高于第二PDSCH的信道优先级，终端设备需要基于第一终端设备处理能力接收第二PDSCH；其中，终端设备在所述第二终端设备处理能力下的物理信道处理时间小于在所述第一终端设备处理能力下的物理信道处理时间。在所述第一PDSCH的结束符号之后的时间间隔阈值内，终端设备不接收和/或不解调第二PDSCH；终端设备接收和/或解调第一PDSCH，即终端设备接收和/或解调 高优先级的下行信道。在该场景下，所述第二下行信道的起始符号与所述第一下行信道的结束符号之间的时间间隔小于所述时间间隔阈值；或者，所述第二下行信道的结束符号与所述第一下行信道的结束符号之间的时间间隔小于所述时间间隔阈值。
其中，终端设备不接收和/或不解调第二PDSCH可以包括下述两种情况：第一种情况为，终端设备不期待接收和/或不期待解调第二PDSCH，即网络设备有调度限制，即不调度第二PDSCH。第二种情况为，不限制网络设备对第二PDSCH的调度，终端设备不接收和/或不解调第二PDSCH；即网络设备可以进行第二PDSCH的调度，但是，终端设备不接收和/或不解调第二PDSCH。
针对该场景进行如下举例说明：若第一PDSCH承载URLLC业务的数据，终端设备基于第二终端设备处理能力接收和/或解调第一PDSCH，网络设备在时间间隔阈值内调度第二PDSCH，第二PDSCH承载eMBB业务的数据，且第二PDSCH信道占用的RB大于136个，第二PDSCH对应的子载波间隔为30MHz；则终端设备不接收和/或不解调第二PDSCH。与已有方案中终端设备放弃解调第一PDSCH、接收和/或解调第二PDSCH相比较，能够保证对时延要求高的URLLC业务不受对时延要求低的eMBB业务的影响。
在另一些场景下，终端设备确定需要在目标时域资源上接收第二PDSCH，所述第二PDSCH需要终端设备基于第一终端设备处理能力接收；若终端设备在第二PDSCH起始符号之前的时间间隔阈值内没有接收和/或解调第一PDSCH，则终端设备接收和/或解调第二PDSCH。其中，终端设备没有接收和/或解调第一PDSCH，可以为网络设备没有发送第一PDSCH。
在又一些场景下，终端设备在目标时域资源上基于第二终端设备处理能力接收但并未解调第一PDSCH，第二PDSCH的信道优先级高于第一PDSCH的信道优先级；则终端设备接收并解调第二PDSCH，并放弃对第一PDSCH的解调。即终端设备接收和/或解调优先级高的第二PDSCH。或者，若所述第一PDSCH的信道优先级等于所述第二PDSCH的信道优先级，则终端设备解调传输时间在前的第一PDSCH，不接收和/或不解调传输时间在后的第二PDSCH。或者，若所述第一PDSCH的信道优先级等于所述第二PDSCH的信道优先级，则终端设备接收和/或解调传输时间在后的第二PDSCH，不解调传输时间在前的第一PDSCH。如此，在优先级相同的两个PDSCH被调度传输时，通过接收和/或解调传输时间在后的PDSCH，保证 了在后传输的PDSCH的传输性能。或者，若所述第一PDSCH的信道优先级等于所述第二PDSCH的信道优先级，则终端设备接收和/或解调传输时间在前的第二PDSCH，不解调传输时间在后的第二PDSCH。如此，在优先级相同的两个PDSCH被调度传输时，通过接收和/或解调传输时间在前的PDSCH，保证了在前传输的PDSCH的传输性能。在该场景下，所述第二下行信道的起始符号与所述第一下行信道的结束符号之间的时间间隔小于所述时间间隔阈值，或者所述第二下行信道的结束符号与所述第一下行信道的结束符号之间的时间间隔小于所述时间间隔阈值。
还有一些场景下，终端设备确定需要在目标时域资源上接收第二PDSCH，所述第二PDSCH需要基于第一终端设备处理能力被终端设备接收，第二PDSCH的优先级高于第一PDSCH的优先级，则终端设备不解调第一PDSCH，终端设备接收和/或解调第二PDSCH；即终端设备接收和/或解调优先级高的下行信道。若第一PDSCH的优先级等于第一PDSCH的优先级，则终端设备接收和/或解调传输时间在后的第二PDSCH，不解调传输时间在前的第一PDSCH。如此，在优先级相同的两个PDSCH被调度传输时，通过接收和/或解调传输时间在后的PDSCH，保证了在后传输的PDSCH的传输性能。或者，若所述第一PDSCH的信道优先级等于所述第二PDSCH的信道优先级，则终端设备接收和/或解调传输时间在前的第二PDSCH，不解调传输时间在后的第二PDSCH。如此，在优先级相同的两个PDSCH被调度传输时，通过接收和/或解调传输时间在前的PDSCH，保证了在前传输的PDSCH的传输性能。在该场景下，所述第一下行信道的结束符号与所述第二下行信道起始符号之间的时间间隔小于所述时间间隔阈值，或者所述第一下行信道的起始符号与所述第二下行信道起始符号之间的时间间隔小于所述时间间隔阈值。
