- the CG mechanism is a data transmission mechanism suitable for uplink periodic service transmission.
- resources for uplink data transmission also called CG resources
- DCI downlink control information
- the CG resource may also be referred to as a CG transmission opportunity in the time domain.
- the CG mechanism may sometimes be called a configured scheduling (CS) mechanism or a grant free (GF) mechanism.
- the CG mechanism includes two types: CG Type 1 and CG Type 2.
- CG Type 1 The workflows of these two CG types are introduced respectively below.
- the radio access network device provides CG configuration information, such as CG period information, CG resource information, etc., to the terminal through RRC messages.
- the CG configuration information is also used to activate the CG configuration.
- the terminal can send uplink data to the wireless access network device based on the CG period information and the CG resource information.
- the radio access network device can also instruct the terminal to deactivate the CG configuration by sending DCI to the terminal. After receiving the DCI, the terminal may release the CG resource, or it may also be understood as stopping/suspending uplink data transmission on the CG resource.
- the radio access network device provides CG configuration information, such as CG cycle information, for the terminal through RRC messages.

- the radio access network device may also instruct the terminal to deactivate the CG configuration by sending another DCI to the terminal. After receiving the DCI, the terminal may release the CG resource, or it may also be understood as stopping/suspending uplink data transmission on the CG resource.
- the SPS mechanism is a data transmission mechanism suitable for downlink periodic service transmission.
- resources for downlink data transmission also called SPS resources
- SPS resources can be allocated to the terminal by means of RRC messages or DCI during the downlink data transmission process, so that the terminal can periodically reuse the allocated resources for downlink Data reception.
- the SPS resource may also be referred to as an SPS transmission opportunity in the time domain.
- the radio access network device provides the terminal with SPS configuration information, such as SPS cycle information and/or SPS resource information, etc. through an RRC message.
- the radio access network device further instructs the terminal to activate the SPS configuration through the DCI.
- the terminal may receive downlink data from the radio access network device based on the SPS period information and the SPS resource information.
- the radio access network device may also instruct the terminal to deactivate the SPS configuration by sending another DCI to the terminal. After receiving the DCI, the terminal may release the SPS resource, or it may also be understood as stopping/suspending downlink data reception on the SPS resource.
- XR or video service data usually has a certain frame rate and periodicity, so the CG mechanism and SPS mechanism are also suitable for transmitting such periodic XR or video service data.
- XR data is generally transmitted in the form of picture frames, and the same picture frame can usually be processed into multiple data packets.
- the same picture frame can be divided into multiple Internet protocol (Internet protocol, IP) packets, which are transmitted from the terminal to the base station side of the radio access network (RAN), and then transmitted to the server through the core network for rendering.
- IP Internet protocol
- RAN radio access network
- picture frames usually use source coding for data compression, there is generally a certain dependency between multiple IP packets in one picture frame. As shown in FIG. 7, during the transmission process, if an IP packet transmission error occurs, the entire picture frame cannot be recovered. Only when all IP packets corresponding to the picture frame are successfully transmitted, the picture frame can be correctly restored at the receiving end.
- the terminal generally has a certain terminal capability, and based on the terminal capability, the terminal generally needs a certain amount of processing time to decode and recover downlink data and control information.
- the terminal For example, for receiving downlink data (such as downlink data carried on a physical downlink shared channel (PDSCH)), the terminal generally needs a certain processing time. For example, take the processing time for the terminal to receive downlink data to be 2 time slots as an example.
- the terminal For another example, for receiving control information (such as control information carried on a physical downlink control channel (PDCCH)), the terminal generally requires a certain amount of processing time. For example, take the processing time for the terminal to receive the control information to be 2 time slots as an example.
- PDSCH physical downlink shared channel
- FIG. 8 shows the influence of delay constraint on picture frame transmission under the SPS mechanism.
- FIG. 8 shows 11 time slots between the arrival time of the downlink picture frame and the latest reception time of the picture frame. Since XR data has strict transmission delay requirements, all data of this downlink picture frame must be correctly received by the receiving side (such as the terminal) within these 11 time slots (that is, before the latest reception time of the indicated picture frame) It is possible to satisfy the experience of the user on the receiving side. If the receiving side correctly receives all the data of the downlink picture frame after the indicated latest receiving time of the picture frame, the user's receiving experience will be degraded due to the impact of delay.
- D in the figure represents a downlink time slot, which is used to transmit downlink signals or downlink information
- U represents an uplink time slot, which is used to transmit uplink signals or uplink information.
- the time slot distribution shown in FIG. 8 can be understood as the time slot configuration configured by the radio access network device for the terminal. Among them, the 3rd to 8th downlink time slots belong to the SPS transmission opportunity.
- the retransmission time corresponding to the SPS transmission opportunity may be related to the time slot configuration and terminal capability of the terminal.
- the terminal tries to receive downlink data from the network device at the first SPS transmission opportunity in Figure 8, after the processing time of 2 time slots, it is determined that the reception error is received, and at this time the terminal needs to feed back to the network device An incorrect negative acknowledgment (negative acknowledgment, NACK), so that the network device can retransmit the erroneously received data to the terminal.
- NACK negative acknowledgment

可以理解,图2-图5仅给出了本申请实施例可以适用的几种场景示意,并没有对本申请实施例的适用场景产生限定。
下面结合附图对本申请的技术方案进行说明。
另外为便于理解本申请的技术方案,首先对XR或者视频业务的特点以及配置授权(configured grant,CG)机制和半静态调度(semi-persistent scheduling,SPS)机制进行简要介绍。
对于XR或者视频业务数据,其通常具有一定的帧率和周期性。以图6为例,给出了帧率为60帧每秒(frame per second,FPS)的情况下,XR业务的画面帧在时间上的分布示意图。从图6中可以看出,在60FPS的情况下,每隔1000/60≈16.67ms会出现或到达一个画面帧。
其他可能的帧率还包括30FPS、90FPS以及120FPS。无线接入网设备可以通过多种不同的方式获得XR或视频业务数据的帧率。
例如,无线接入网设备可以通过与数据对应的服务质量(quality of service,QoS)流的配置信息,例如QoS模板(QoS profile),获得XR或视频业务数据的帧率。又例如,无线接入网设备可以通过检测QoS流中数据包的到达时间间隔来获得XR或视频业务数据的帧率。又例如,终端可以通过辅助信息,例如信元UEAssistanceInformation,将上行数据的帧率或者是与帧率有关的信息上报给无线接入网设备。
终端也可以通过多种不同的方式获得XR或视频业务数据的帧率。
例如,终端可以通过与数据对应的QoS流的配置信息,例如QoS规则(QoS rule),获得XR或视频业务数据的帧率。又例如,终端可以通过检测QoS流中数据包的到达时间间隔来获得XR或视频业务数据的帧率。又例如,终端可以通过协议层间的交互,将应用层数据的帧率或者是与帧率有关的信息通知给终端的应用层以下的协议层(例如RRC层)。
CG机制是一种适合于进行上行周期性业务传输的数据传输机制。通过CG机制,可以在上行数据传输过程中,借助RRC消息或下行控制信息(downlink control information,DCI)为终端分配用于上行数据传输的资源(也可以称为CG资源),使得终端可以周期性地重复使用该分配的资源进行上行数据传输。其中,CG资源在时域上也可以被称为CG传输时机。CG机制有时也可以被称为配置调度(configured scheduling,CS)机制或免授权(grant free,GF)机制。
CG机制包括两种类型:CG类型1和CG类型2。下面分别介绍这两种CG类型的工作流程。
●CG类型1:
在CG类型1中,无线接入网设备通过RRC消息为终端提供CG配置信息,例如CG周期信息、CG资源信息等。CG配置信息还用于激活CG配置,终端在收到CG配置信息后,可以基于CG周期信息和CG资源信息向无线接入网设备发送上行数据。
在CG类型1中,无线接入网设备还可以通过向终端发送DCI,指示终端去激活CG配 置。终端在接收到该DCI后,可以释放CG资源,或者也可以理解为停止/暂停在该CG资源上的上行数据发送。
●CG类型2:
在CG类型2中,无线接入网设备通过RRC消息为终端提供CG配置信息,例如CG周期信息等。无线接入网设备进一步通过DCI向终端指示CG资源信息。终端在收到该DCI后,可以基于CG周期信息和CG资源信息向无线接入网设备发送上行数据。上述DCI也可以理解为用于指示并激活了CG资源。
在CG类型2中,无线接入网设备还可以通过向终端发送另一个DCI,指示终端去激活CG配置。终端在接收到该DCI后,可以释放CG资源,或者也可以理解为停止/暂停在该CG资源上的上行数据发送。
SPS机制是一种适合于进行下行周期性业务传输的数据传输机制。通过SPS机制,可以在下行数据传输过程中,借助RRC消息或DCI为终端分配用于下行数据传输的资源(也可以称为SPS资源),使得终端可以周期性地重复使用该分配的资源进行下行数据接收。其中,SPS资源在时域上也可以被称为SPS传输时机。
在SPS机制中,无线接入网设备通过RRC消息为终端提供SPS配置信息,例如SPS周期信息和/或SPS资源信息等。无线接入网设备进一步通过DCI向终端指示激活SPS配置。终端在收到该DCI后,可以基于SPS周期信息和SPS资源信息接收来自无线接入网设备的下行数据。
在SPS机制中,无线接入网设备还可以通过向终端发送另一个DCI,指示终端去激活SPS配置。终端在接收到该DCI后,可以释放SPS资源,或者也可以理解为停止/暂停在该SPS资源上的下行数据接收。
如前所述,对于XR或者视频业务数据,其通常具有一定的帧率和周期性,因此CG机制和SPS机制也适合于传输这种具有周期性的XR或者视频业务数据。
XR数据一般以画面帧的形式进行传输,同一画面帧通常可以被处理为多个数据包。例如,同一画面帧可以被分成多个网际协议(Internet protocol,IP)包,由终端传输到无线接入网(radio access network,RAN)的基站侧,再经过核心网,传输到服务器进行渲染。由于画面帧通常会采用信源编码进行数据压缩,一个画面帧的多个IP包之间一般具有一定的依赖关系。如图7所示,在传输过程中,如果一个IP包传输出错,会导致整个画面帧无法恢复。只有当该画面帧对应的所有IP包都传输成功时,该画面帧才能在接收端被正确恢复。
可见,在XR数据的传输过程中,画面帧中的一部分数据传输出错或者传输超过时延预算时,即便该画面帧的其他数据传输正确,该画面帧也无法被正确接收。因此如何能够高效利用有限的无线资源提高XR数据的传输效率是一个亟待解决的问题。
终端一般具有一定的终端能力,终端基于终端能力对解码恢复下行数据和控制信息一般需要一定的处理时间。例如对于下行数据(比如承载在物理下行共享信道(physical downlink shared channel,PDSCH)上的下行数据)的接收而言,终端一般需要一定的处理时间。比如,以终端接收下行数据的处理时间为2个时隙为例。又例如对于控制信息(比如承载在物理下行控制信道(physical downlink control channel,PDCCH)上的控制信息)的接收而言,终端一般也需要一定的处理时间。比如,以终端接收控制信息的处理时间为2个时隙为例。
以图8为例,示出了一种SPS机制下时延约束对画面帧传输的影响。图8中示意出下行的画面帧到达时刻至画面帧最晚接收时刻之间的11个时隙。由于XR数据有着严格的传输时延要求,这一下行画面帧的所有数据必须在这11个时隙内(即示意的画面帧最晚接收时刻之 之前)被接收侧(例如终端)正确接收才有可能满足接收侧用户的体验。倘若接收侧在示意的画面帧最晚接收时刻之后才正确接收完该下行画面帧的所有数据,用户将会因为时延的影响导致接收体验下降。图中的“D”代表下行时隙,用于传输下行信号或下行信息;“U”代表上行时隙,用于传输上行信号或上行信息。图8示意出来的时隙分布可以理解为无线接入网设备为终端配置的时隙配置。其中,第3-8个下行时隙属于SPS传输时机。
SPS传输时机对应的重传时间可以与终端的时隙配置和终端能力有关。
例如,如果终端在图8中的第一个SPS传输时机上尝试接收来自网络设备的下行数据,经过2个时隙的处理时间后,确定接收错误,此时终端需要向网络设备反馈针对该接收错误的否定应答(negative acknowledgment,NACK),以便于网络设备可以向终端重传该错误接收的数据。由于图8中只有第二个“U”时隙能满足终端在2个时隙的处理时间后进行NACK的反馈,因此网络设备可以在画面帧最晚接收时刻前的一个“D”时隙向终端重传该错误接收的数据。图8中以斜线纹示意的SPS传输时机对应的重传时机都是在画面帧最晚接收时刻前的一个“D”时隙。
又例如,如果终端在图8中以点状纹示意的SPS传输时机(第五个或第六个SPS传输时机)上尝试接收来自网络设备的下行数据,经过2个时隙的处理时间后,确定接收错误,此时终端在画面帧最晚接收时刻之前没有机会向网络设备反馈针对该接收错误的NACK。这是由于上述时隙配置和终端能力使得点状纹示意的SPS传输时机对应的重传时间超过了画面帧的最晚接收时刻,导致这一画面帧的部分接收错误的数据无重传机会,从而使得这一画面帧在接收侧无法被正确恢复。
再以图9为例,示出了一种CG机制下时延约束对画面帧传输的影响。如上述示例,以终端接收控制信息的处理时间为2个时隙的终端能力为例。与图8类似的,CG传输时机对应的重传时间也可以与终端的时隙配置和终端能力有关。在图9中,一个画面帧最晚接收时刻前的两个由点状纹示意的CG传输时机上传输错误的该画面帧的上行数据因为时延约束,导致没有重传机会,这是由于图9示意的时隙配置和上述终端能力使得点状纹示意的CG传输时机对应的重传时间超过了画面帧的最晚接收时刻,从而使得这一画面帧在接收侧无法被正确恢复。
本申请中提供了一种数据传输方法,可以通过及时调整在预先配置的部分传输时机上的数据传输,使得预先配置的传输时机可以更好地适配XR数据对传输时延等方面的要求,可以更加高效地利用预先配置的无线资源提高XR数据的传输效率,从而提升用户体验。可以理解,本申请提供的方法并不限制其应用的数据业务类型,XR和或者视频业务数据之外的数据业务类型也同样适用。
图10为本申请实施例提供的一种数据传输方法1000的交互示意图。图10中以无线接入网设备和终端作为该交互示意的执行主体为例来示意该方法,但本申请并不限制该交互示意的执行主体。例如,图10中的无线接入网设备也可以是支持该无线接入网设备实现该方法的芯片、芯片***、或处理器,还可以是能实现全部或部分无线接入网设备功能的逻辑模块或软件;图10中的终端也可以是支持该终端实现该方法的芯片、芯片***、或处理器,还可以是能实现全部或部分终端功能的逻辑模块或软件。如图10所示,该实施例的方法1000可包括1010部分、1020部分、1030部分和1040部分。
1010部分:无线接入网设备向终端发送配置信息,相应地,终端接收该配置信息。该配置信息用于配置多个传输时机。
1020部分:终端和无线接入网设备在一个或多个第一传输时机上进行数据传输,这一个 或多个第一传输时机为上述多个传输时机中的部分传输时机。
1030部分:无线接入网设备向终端发送调整信息,相应地,终端接收该调整信息。该调整信息用于指示在一个或多个第二传输时机上的数据传输,该一个或多个第二传输时机为上述多个传输时机中的部分传输时机,并且该一个或多个第二传输时机不同于上述一个或多个第一传输时机。该调整信息可以包含在DCI中,由PDCCH承载。
1040部分:无线接入网设备在一个或多个第二传输时机上与终端进行数据传输。相应地,终端根据调整信息在一个或多个第二传输时机上与无线接入网设备进行数据传输。
可以理解,在方法1000中,1020部分在1010部分之后执行,1040部分在1030部分之后执行,但并不限定其他部分之间的执行顺序。
如图11A所示,无线接入网设备通过配置信息预先为终端配置多个传输时机,通过调整信息调整其中部分传输时机上的数据传输。在预先配置的传输时机中,被调整信息所调整的传输时机被称为第二传输时机,未被调整信息所调整的传输时机被称为第一传输时机。在第二传输时机上,终端根据调整信息与无线接入网设备进行数据传输。而在第一传输时机上的数据传输则不会受到调整信息的调整。图11A中仅以在第二传输时机的前一个传输时机接收到调整信息为例,但这并不限制接收调整信息的时间。在图11A中,只要接收到调整信息的时间不晚于第二传输时机即可。
又如图11B所示,无线接入网设备通过配置信息预先为终端配置多个传输时机,并且这些传输时机是周期性出现的。上述调整信息可以调整一个周期内的第二传输时机上的数据传输,而不影响后续周期中的数据传输。如在图11B中,终端在图中的第一个周期内收到调整信息,因此该调整信息调整的是这个周期内的最后两个传输时机,从而这个周期内的最后两个传输时机为第二传输时机,而这个周期内的其他传输时机以及后续周期内的传输时机仍然是第一传输时机,所以这个调整信息所指示的调整也可以理解成一种临时的调整,“临时”的含义是指,该调整信息对接收到调整信息的周期内的传输时机起调整作用,对接收到调整信息的周期外的传输时机不起调整作用。
在方法1000中,配置信息可以预先配置多个传输时机用于周期性的数据传输。调整信息可以根据实际数据传输的需要,及时调整预先被配置的多个传输时机中的部分传输时机上的数据传输,使得预先配置的传输时机可以更好地适配数据(如XR数据)对传输时延等方面的要求,可以更加高效地利用预先配置的无线资源提高数据的传输效率,从而提升用户体验。
图12为方法1000的一种具体实施方法1200的交互示意图,方法1200可以理解为在SPS机制下方法1000的具体实现。方法1200中包括1210部分、1220部分、1230部分和1240部分,分别对应于方法1000中1010部分、1020部分、1030部分和1040部分。
1210部分:无线接入网设备向终端发送SPS配置信息,相应地,终端接收该SPS配置信息。该SPS配置信息用于配置多个SPS传输时机。即,方法1000中的配置信息为SPS配置信息,传输时机为SPS传输时机。SPS配置信息可以由RRC消息承载,通过该SPS配置信息,终端能够知道SPS传输时机在时域上的位置。
1220部分:终端在一个或多个第一SPS传输时机上与无线接入网设备进行数据传输,这一个或多个第一SPS传输时机为多个SPS传输时机中的部分SPS传输时机。即,方法1000中的第一传输时机为第一SPS传输时机。具体而言,在SPS机制下,无线接入网设备在一个或多个第一SPS传输时机上向终端发送下行数据,相应地,终端在这一个或多个第一SPS传输时机上接收来自无线接入网设备的下行数据。
在方法1200中,可选地,还包括1250部分:无线接入网设备向终端发送第一激活信息, 该第一激活信息用于激活在一个或多个第一SPS传输时机上的数据传输。相应地,终端接收来自无线接入网设备的第一激活信息,并且在1220部分中,终端根据第一激活信息在一个或多个第一SPS传输时机上与无线接入网设备进行数据传输。该第一激活信息可理解为用于对由SPS配置信息预先配置的SPS传输时机的激活。该第一激活信息可以包含在DCI中,由PDCCH承载。
可以理解,在没有1230部分中的调整信息的情况下,SPS配置信息所配置的一个或多个SPS传输时机均为第一SPS传输时机,即在没有收到1230部分中的调整信息的情况下,终端将依据第一激活信息在配置信息所预先配置的一个或多个SPS传输时机上与无线接入网设备进行数据传输。
可选地,第一激活信息由第一无线网络临时标识(radio network temporary identifier,RNTI)加扰,前述调整信息由第二RNTI加扰。
在一种可能的设计中,第一RNTI与第二RNTI不同,此时终端可以通过RNTI区分出第一激活信息和调整信息。可选地,第一RNTI为配置调度RNTI(configured scheduling RNTI,CS-RNTI),第二RNTI为不同于CS-RNTI的另一个RNTI,例如第二RNTI可被称为CS-RNTI-Type2,也可以是其他不同于CS-RNTI的RNTI,本申请对此不做限定。
在另一种可能的设计中,第一RNTI与第二RNTI相同,且调整信息与第一激活信息均包括第一字段,其中调整信息中的第一字段被设置为预定值,此时终端可以通过第一字段区分出第一激活信息和调整信息,即当终端发现第一字段被设置为预定值时,可以识别出该信息为前述的调整信息。可选地,第一RNTI和第二RNTI都是CS-RNTI。可选地,第一字段可以是DCI中的冗余版本(redendancy version,RV)字段,预定值可以是0以外的保留值。
1230部分:无线接入网设备向终端发送调整信息,相应地,终端接收该调整信息。该调整信息用于指示在一个或多个第二SPS传输时机上的数据传输,该一个或多个第二SPS传输时机为上述多个SPS传输时机中的部分SPS传输时机,并且该一个或多个第二SPS传输时机不同于上述一个或多个第一SPS传输时机。即,方法1200中的第二传输时机为第二SPS传输时机。
1240部分:无线接入网设备在一个或多个第二SPS传输时机上与终端进行数据传输。相应地,终端根据调整信息在一个或多个第二SPS传输时机上与无线接入网设备进行数据传输。具体而言,在SPS机制下,无线接入网设备在一个或多个第二SPS传输时机上向终端发送下行数据,相应地,终端在这一个或多个第二SPS传输时机上接收来自无线接入网设备的下行数据。
在方法1200中,无线接入网设备可以通过调整信息及时调整终端在预先配置的部分SPS传输时机上的数据传输,使得预先配置的SPS传输时机可以更好地适配数据对传输时延等方面的要求,可以更加高效地利用预先配置的SPS资源提高数据的传输效率,从而提升用户体验。同时,该方法也不影响预先配置的其他SPS传输时机上的数据传输,在提升用户对数据接收体验的同时,也尽可能降低对其他数据传输的影响。
以图13为例,终端接收了来自无线接入网设备的SPS配置信息后,可以知道SPS传输时机的周期,以及SPS传输时机在周期内的时域分布,从而可以知道SPS传输时机在时域上的位置(如图中有底纹示意的)。随后终端收到来自无线接入网设备的第一激活信息,从而激活了在预先配置的SPS传输时机上进行数据传输。终端在图13中示意的SPS传输时机的周期内接收到了调整信息,该调整信息用于调整该周期内最后两个SPS传输时机的数据传输。因此,除了图13示意的SPS传输时机的周期内的最后两个SPS传输时机是第二SPS传输时 机以外,其他的SPS传输时机是第一SPS传输时机。终端在第一SPS传输时机上可依据第一激活信息接收来自无线接入网设备的下行数据,在第二SPS传输时机上则依据调整信息接收来自无线接入网设备的下行数据。
在方法1200的一种可能的实施方式中,第一激活信息包括第一调制编码方案(modulation and coding scheme,MCS)信息,调整信息包括第二MCS信息。其中,第一MCS信息指示一个或多个第一SPS传输时机中每个第一SPS传输时机的MCS,第二MCS信息指示一个或多个第二SPS传输时机中每个第二SPS传输时机的MCS。可选地,第二MCS信息指示的MCS低于第一MCS信息指示的MCS。例如,第二MCS信息指示的调制阶数低于第一MCS信息指示的调制阶数。又例如,第二MCS信息指示的码率低于第一MCS信息指示的码率。再例如,第二MCS信息指示的调制阶数低于第一MCS信息指示的调制阶数,并且第二MCS信息指示的码率低于第一MCS信息指示的码率。该实施方式可理解为:当画面帧的最晚接收时刻Tlatest1、第二SPS传输时机的时刻Tsecond1和第二SPS传输时机对应的重传时间Tretrans1满足Tlatest1–Tsecond1<Tretrans1时,无线接入网设备向终端发送的调整信息所包含的第二MCS信息指示的MCS低于第一激活信息中第一MCS信息指示的MCS。可选地,第二SPS传输时机对应的重传时间Tretrans1与终端的时隙配置和终端能力有关。关于SPS传输时机对应的重传时间与终端的时隙配置和终端能力有关的描述可以参考前面对于图8的描述,此处不再赘述。
在该实施方式中,第一SPS传输时机上传输的数据和第二SPS传输时机上传输的数据可以属于同一个画面帧。在第二SPS传输时机包含充足的SPS资源,并且该画面帧的最晚接收时刻Tlatest1、第二SPS传输时机的时刻Tsecond1和第二SPS传输时机对应的重传时间Tretrans1满足Tlatest1–Tsecond1<Tretrans1时,通过上述调整信息向终端指示在第二SPS传输时机上采用更低的MCS,提升第二SPS传输时机上数据传输的可靠性,以降低第二SPS传输时机上传输数据的重传概率,从而尽可能降低数据传输的时延,提升用户对数据的接收体验。
本申请中传输时机对应的重传时间(例如第二SPS传输时机对应的重传时间或第二CG传输时机对应的重传时间)可以理解为,重传该传输时机上的数据需要等待的时间间隔或最短时间间隔。本申请中画面帧的最晚接收时刻可以理解为,接收侧(例如终端)在不晚于这个最晚接收时刻完成画面帧数据的接收,能成功恢复出该画面帧;如果在这个时刻之后完成画面帧数据的接收,将无法成功恢复出该画面帧。
仍以图13为例,在图中示意的SPS传输时机的周期内共有6个SPS传输时机,以SPS配置信息配置的每个第一SPS传输时机可以传输10000比特的数据、传输的画面帧共有50000比特的数据为例。图13中还示意了画面帧的最晚接收时刻Tlatest1、第二SPS传输时机的时刻Tsecond1以及第二SPS传输时机对应的重传时间Tretrans1。无线接入网设备在SPS传输时机的周期内的前四个第一SPS传输时机上共传输了40000比特的数据。以图8示意的情况为例,对于SPS传输时机的周期内的最后两个SPS传输时机,由于画面帧要求的时延约束的影响,使得Tlatest1–Tsecond1<Tretrans1,并且这两个SPS传输时机的资源足以承载该画面帧剩余的10000比特,因此无线接入网设备可以向终端发送调整信息,指示终端在这两个第二SPS传输时机上的数据传输会临时降低MCS,例如降低MCS后每个第二SPS传输时机上可以承载5000比特的数据,从而可以提升这两个第二SPS传输时机上数据传输的可靠性,降低这两个第二SPS传输时机上传输数据的重传概率,以尽可能避免需要重传但无法在规定时间内完成重传而导致的整个画面帧的接收失败。
在方法1200的另一种可能的实施方式中,除了包含前述的第一MCS信息,第一激活信息还包括第一频域资源分配(frequency domain allocation assignment,FDRA)信息;除了包含前述的第二MCS信息,调整信息还包括第二FDRA信息。其中,第一FDRA信息指示一个或多个第一SPS传输时机中每个第一SPS传输时机的频域资源,第二FDRA信息指示一个或多个第二SPS传输时机中每个第二SPS传输时机的频域资源。可选地,第二MCS信息指示的MCS低于第一MCS信息指示的MCS;第二FDRA信息指示的频域资源多于第一FDRA信息指示的频域资源。该实施方式可理解为:当画面帧的最晚接收时刻Tlatest1、第二SPS传输时机的时刻Tsecond1和第二SPS传输时机对应的重传时间Tretrans1满足Tlatest1–Tsecond1<Tretrans1时,无线接入网设备向终端发送的调整信息所包含的第二MCS信息指示的MCS低于第一激活信息中第一MCS信息指示的MCS,并且调整信息所包含的第二FDRA信息指示的频域资源多于第一激活信息中第一FDRA信息指示的频域资源。可选地,第二SPS传输时机对应的重传时间Tretrans1与终端的时隙配置和终端能力有关。关于SPS传输时机对应的重传时间与终端的时隙配置和终端能力有关的描述可以参考前面对于图8的描述,此处不再赘述。
在该实施方式中,第一SPS传输时机上传输的数据和第二SPS传输时机上传输的数据可以属于同一个画面帧。在第二SPS传输时机包含的资源不足,并且该画面帧的最晚接收时刻Tlatest1、第二SPS传输时机的时刻Tsecond1和第二SPS传输时机对应的重传时间Tretrans1满足Tlatest1–Tsecond1<Tretrans1时,通过为第二SPS传输时机分配更多的资源,提升第二SPS传输时机上数据传输的可靠性,以降低第二SPS传输时机上传输数据的重传概率,从而尽可能降低数据传输的时延,提升用户对数据的接收体验。
以图14A为例,在图中示意的SPS传输时机的周期内共有5个SPS传输时机,以SPS配置信息配置的每个第一SPS传输时机可以传输10000比特的数据、传输的画面帧共有50000比特的数据为例。图14A中还示意了画面帧的最晚接收时刻Tlatest1、第二SPS传输时机的时刻Tsecond1以及第二SPS传输时机对应的重传时间Tretrans1。无线接入网设备在SPS传输时机的周期内的前四个第一SPS传输时机上共传输了40000比特的数据。对于SPS传输时机的周期内的最后一个SPS传输时机,以类似与图8描述的原因为例,由于画面帧要求的时延约束的影响,使得Tlatest1–Tsecond1<Tretrans1。此时如果通过调整信息降低了这个第二SPS传输时机上的MCS,会导致该第二SPS传输时机上可以承载的比特数减少,无法承载完剩余的10000比特。因此,此时除了包含前述用于降低第二SPS传输时机上MCS的第二MCS信息以外,调整信息还包含第二FDRA信息,用于临时增加第二SPS传输时机上的频域资源,使得第二SPS传输时机上MCS降低的同时依然能够承载完剩余的10000比特。同时,由于MCS的降低,可以提升这个第二SPS传输时机上数据传输的可靠性,降低这个第二SPS传输时机上传输数据的重传概率,以尽可能避免需要重传但无法在规定时间内完成重传而导致的整个画面帧的接收失败。
在方法1200的另一种可能的实施方式中,除了向终端发送上述包括第一MCS信息的第一激活信息和包括第二MCS信息的调整信息,方法1200还包括:无线接入网设备向终端发送第一调度信息,该第一调度信息用于调度在前述多个SPS传输时机以外的时域资源上的数据传输;在上述多个SPS传输时机以外的时域资源上与该终端进行数据传输。相应地,终端接收该第一调度信息,并根据第一调度信息在上述多个SPS传输时机以外的时域资源上与无线接入网设备进行数据传输。在SPS传输时机以外的时域资源上的数据传输也可以称为非SPS的数据传输。
在该实施方式中,第一SPS传输时机上传输的数据和第二SPS传输时机上传输的数据可以属于同一个画面帧。在上述第二SPS传输时机包含的资源不足,并且该画面帧的最晚接收时刻Tlatest1、第二SPS传输时机的时刻Tsecond1和第二SPS传输时机对应的重传时间Tretrans1满足Tlatest1–Tsecond1<Tretrans1时,通过额外调度SPS传输时机以外的资源用于该画面帧数据的传输,从而尽可能降低数据传输的时延,提升用户对数据的接收体验。
以图14B为例,在图中示意的SPS传输时机的周期内共有5个SPS传输时机,以SPS配置信息配置的每个第一SPS传输时机可以传输10000比特的数据、传输的画面帧共有50000比特的数据为例。图14B中还示意了画面帧的最晚接收时刻Tlatest1、第二SPS传输时机的时刻Tsecond1以及第二SPS传输时机对应的重传时间Tretrans1。无线接入网设备在SPS传输时机的周期内的前四个第一SPS传输时机上共传输了40000比特的数据。对于SPS传输时机的周期内的最后一个SPS传输时机,以类似与图8描述的原因为例,由于画面帧要求的时延约束的影响,使得Tlatest1–Tsecond1<Tretrans1。此时如果通过调整信息降低了这个第二SPS传输时机上的MCS,会导致该第二SPS传输时机上可以承载的比特数减少,例如减少到5000比特。因此,此时除了向终端发送包含第二MCS信息的调整信息以外,无线接入网设备还向终端发送第一调度信息,用于调度SPS传输时机以外的时域资源(图中横向条纹所示意的),使得该额外调度的时域资源上能够承载完剩余的5000比特。由于第二SPS传输时机上MCS的降低,可以提升这个第二SPS传输时机上数据传输的可靠性,降低这个第二SPS传输时机上传输数据的重传概率,以尽可能避免需要重传但无法在规定时间内完成重传而导致的整个画面帧的接收失败。
在方法1200中,可选地,还包括:无线接入网设备向终端发送SPS去激活信息,该SPS去激活信息用于去激活SPS的配置。终端接收SPS去激活信息,并基于该SPS去激活信息停止/暂停在SPS传输时机上的下行数据接收。SPS去激活信息可包含在DCI中,通过PDCCH承载。
图15为方法1000的另一种具体实施方法1500的交互示意图,方法1500可以理解为在CG机制下方法1000的具体实现。方法1500中包括1510部分、1520部分、1530部分和1540部分,分别对应于方法1000中1010部分、1020部分、1030部分和1040部分。
1510部分:无线接入网设备向终端发送CG配置信息,相应地,终端接收该CG配置信息。该CG配置信息用于配置多个CG传输时机。即,方法1000中的配置信息为CG配置信息,传输时机为CG传输时机。CG配置信息可以由RRC消息承载,通过该CG配置信息,终端能够知道CG传输时机在时域上的位置。
1520部分:终端在一个或多个第一CG传输时机上与无线接入网设备进行数据传输,这一个或多个第一CG传输时机为多个CG传输时机中的部分CG传输时机。即,方法1000中的第一传输时机为第一CG传输时机。具体而言,在CG机制下,终端在这一个或多个第一CG传输时机上向无线接入网设备发送上行数据,相应地,无线接入网设备在这一个或多个第一CG传输时机上接收来自终端的上行数据。
可以理解,在没有1530部分中的调整信息的情况下,CG配置信息所配置的一个或多个CG传输时机均为第一CG传输时机,即在没有收到1530部分中的调整信息的情况下,终端将依据第二激活信息在配置信息所预先配置的一个或多个CG传输时机上与无线接入网设备进行数据传输。
如前所述,CG机制包括CG类型1和CG类型2。
在CG类型1中,1510部分中的CG配置信息不仅用于配置多个CG传输时机,还用于 激活CG配置,即终端根据CG配置信息在一个或多个第一CG传输时机上与无线接入网设备进行数据传输。
在CG类型2中,方法1500中还可选地包括1550部分:无线接入网设备向终端发送第二激活信息,该第二激活信息用于激活在一个或多个第一CG传输时机上的数据传输。相应地,终端接收来自无线接入网设备的第二激活信息,并且在1520部分中,终端根据第二激活信息在一个或多个第一CG传输时机上与无线接入网设备进行数据传输。该第二激活信息可理解为用于对由CG配置信息预先配置的CG传输时机的激活。该第二激活信息可以包含在DCI中,由PDCCH承载。
可选地,第二激活信息由第三RNTI加扰,前述调整信息由第四RNTI加扰。
在一种可能的设计中,第三RNTI与第四RNTI不同,此时终端可以通过RNTI区分出第二激活信息和调整信息。可选地,第三RNTI为CS-RNTI,第四RNTI为不同于CS-RNTI的另一个RNTI,例如第四RNTI可被称为CS-RNTI-Type2,也可以是其他不同于CS-RNTI的RNTI,本申请对此不做限定。
在另一种可能的设计中,第三RNTI与第四RNTI相同,且调整信息与第二激活信息均包括第二字段,其中调整信息中的第二字段被设置为预定值,此时终端可以通过第二字段区分出第二激活信息和调整信息,即当终端发现第二字段被设置为预定值时,可以识别出该信息为前述的调整信息。可选地,第三RNTI和第四RNTI都是CS-RNTI。可选地,第二字段可以是DCI中的RV字段,预定值可以是0以外的保留值。
1530部分:无线接入网设备向终端发送调整信息,相应地,终端接收该调整信息。该调整信息用于指示在一个或多个第二CG传输时机上的数据传输,该一个或多个第二CG传输时机为上述多个CG传输时机中的部分CG传输时机,并且该一个或多个第二CG传输时机不同于上述一个或多个第一CG传输时机。即,方法1500中的第二传输时机为第二CG传输时机。
1540部分:无线接入网设备在一个或多个第二CG传输时机上与终端进行数据传输。相应地,终端根据调整信息在一个或多个第二CG传输时机上与无线接入网设备进行数据传输。具体而言,在CG机制下,终端在这一个或多个第二CG传输时机上向无线接入网设备发送上行数据,相应地,无线接入网设备在这一个或多个第二CG传输时机上接收来自终端的上行数据。
在方法1500中,无线接入网设备可以通过调整信息及时调整终端在预先配置的部分CG传输时机上的数据传输,使得预先配置的CG传输时机可以更好地适配数据对传输时延等方面的要求,可以更加高效地利用预先配置的CG资源提高数据的传输效率,从而提升用户体验。同时,该方法也不影响预先配置的其他CG传输时机上的数据传输,在提升用户对数据接收体验的同时,也尽可能降低对其他数据传输的影响。
以图16为例,终端接收了来自无线接入网设备的CG配置信息后,可以知道CG传输时机的周期,以及CG传输时机在周期内的时域分布,从而可以知道CG传输时机在时域上的位置(如图中有底纹示意的)。终端根据该CG配置信息,或者随后终端收到来自无线接入网设备的第二激活信息,激活在预先配置的CG传输时机上进行数据传输。终端在图16中示意的CG传输时机的周期内接收到了调整信息,该调整信息用于调整该周期内最后两个CG传输时机的数据传输。因此,除了图16示意的CG传输时机的周期内的最后两个CG传输时机是第二CG传输时机以外,其他的CG传输时机是第一CG传输时机。终端在第一CG传输时机上根据CG配置信息或第二激活信息向无线接入网设备发送上行数据,在第二CG传输时 机上则依据调整信息向无线接入网设备发送上行数据。

在上述的CG类型1或CG类型2的实施方式中,第一CG传输时机上传输的数据和第二CG传输时机上传输的数据可以属于同一个画面帧。在第二CG传输时机包含充足资源,并且该画面帧的最晚接收时刻Tlatest2、第二CG传输时机的时刻Tsecond2和第二CG传输时机对应的重传时间Tretrans2满足Tlatest2–Tsecond2<Tretrans2时,通过上述调整信息向终端指示在第二CG传输时机上采用更低的MCS,提升第二CG传输时机上数据传输的可靠性,以降低第二CG传输时机上传输数据的重传概率,从而尽可能降低数据传输的时延,提升用户对数据的接收体验。
仍以图16为例,在图中示意的CG传输时机的周期内共有6个CG传输时机,以CG配置信息配置的每个第一CG传输时机可以传输10000比特的数据、传输的画面帧共有50000比特的数据为例。图16中还示意了画面帧的最晚接收时刻Tlatest2、第二CG传输时机的时刻Tsecond2以及第二CG传输时机对应的重传时间Tretrans2。无线接入网设备在CG传输时机的周期内的前四个第一CG传输时机上共传输了40000比特的数据。以图9示意的情况为例,对于CG传输时机的周期内的最后两个CG传输时机,由于画面帧要求的时延约束的影响,使得Tlatest2–Tsecond2<Tretrans2,并且这两个CG传输时机的资源足以承载该画面帧剩余的10000比特,因此无线接入网设备可以向终端发送调整信息,指示终端在这两个第二CG传输时机上的数据传输会临时降低MCS,例如降低MCS后每个第二CG传输时机上可以 承载5000比特的数据,从而可以提升这两个第二CG传输时机上数据传输的可靠性,降低这两个第二CG传输时机上传输数据的重传概率,以尽可能避免需要重传但无法在规定时间内完成重传而导致的整个画面帧的接收失败。
在CG类型1的一种可能的实施方式中,除了包含前述的第三MCS信息,CG配置信息还包括第三FDRA信息;除了包含前述的第四MCS信息,调整信息还包括第四FDRA信息。其中,第三FDRA信息配置一个或多个第一CG传输时机中每个第一CG传输时机的频域资源,第四FDRA信息指示一个或多个第二CG传输时机中每个第二CG传输时机的频域资源。可选地,第四FDRA信息指示的频域资源多于第三FDRA信息配置的频域资源。

在上述的CG类型1或CG类型2的实施方式中,第一CG传输时机上传输的数据和第二CG传输时机上传输的数据可以属于同一个画面帧。在第二CG传输时机包含的资源不足,并且该画面帧的最晚接收时刻Tlatest2、第二CG传输时机的时刻Tsecond2和第二CG传输时机对应的重传时间Tretrans2满足Tlatest2–Tsecond2<Tretrans2时,通过为第二CG传输时机分配更多的资源,提升第二CG传输时机上数据传输的可靠性,以降低第二CG传输时机上传输数据的重传概率,从而尽可能降低数据传输的时延,提升用户对数据的接收体验。
以图17A为例,在图中示意的CG传输时机的周期内共有5个CG传输时机,以CG配置信息配置的每个第一CG传输时机可以传输10000比特的数据、传输的画面帧共有50000比特的数据为例。图17A中还示意了画面帧的最晚接收时刻Tlatest2、第二CG传输时机的时刻Tsecond2以及第二CG传输时机对应的重传时间Tretrans2。无线接入网设备在CG传输时机的周期内的前四个第一CG传输时机上共传输了40000比特的数据。对于CG传输时机的周期内的最后一个CG传输时机,以类似与图9描述的原因为例,由于画面帧要求的时延约束的影响,使得Tlatest2–Tsecond2<Tretrans2。此时如果通过调整信息降低了这个第二CG传输时机上的MCS,会导致该第二CG传输时机上可以承载的比特数减少,无法承载完剩余的10000比特。因此,此时除了包含前述用于降低第二CG传输时机上MCS的第四MCS信息/第六MCS信息以外,调整信息还包含第四FDRA信息/第六FDRA信息,用于临时增加第二CG传输时机上的频域资源,使得第二CG传输时机上MCS降低的同时依然能够承载完剩余的10000比特。同时,由于MCS的降低,可以提升这个第二CG传输时机上数据传输的可 靠性,降低这个第二CG传输时机上传输数据的重传概率,以尽可能避免需要重传但无法在规定时间内完成重传而导致的整个画面帧的接收失败。
在CG类型1的一种可能的实施方式中,除了向终端发送上述包括第三MCS信息的CG配置信息和包括第四MCS信息的调整信息,方法1500还包括:无线接入网设备向终端发送第二调度信息,该第二调度信息用于调度在上述多个CG传输时机以外的时域资源上的数据传输;在上述多个CG传输时机以外的时域资源上与该终端进行数据传输。相应地,终端接收该第二调度信息,并根据第二调度信息在上述多个CG传输时机以外的时域资源上与无线接入网设备进行数据传输。本申请中,在CG传输时机以外的时域资源上的数据传输也可以称为非CG的数据传输。
在CG类型2的一种可能的实施方式中,除了向终端发送上述包括第五MCS信息的第二激活信息和包括第六MCS信息的调整信息,方法1500还包括:无线接入网设备向终端发送第三调度信息,该第三调度信息用于调度在上述多个CG传输时机以外的时域资源上的数据传输;在上述多个CG传输时机以外的时域资源上与该终端进行数据传输。相应地,终端接收该第三调度信息,并根据第三调度信息在上述多个CG传输时机以外的时域资源上与无线接入网设备进行数据传输。
在上述的CG类型1或CG类型2的实施方式中,第一CG传输时机上传输的数据和第二CG传输时机上传输的数据可以属于同一个画面帧。在上述第二CG传输时机包含的资源不足,并且该画面帧的最晚接收时刻Tlatest2、第二CG传输时机的时刻Tsecond2和第二CG传输时机对应的重传时间Tretrans2满足Tlatest2–Tsecond2<Tretrans2时,通过额外调度CG传输时机以外的资源用于该画面帧数据的传输,从而尽可能降低数据传输的时延,提升用户对数据的接收体验。
以图17B为例,在图中示意的CG传输时机的周期内共有5个SPS传输时机,以CG配置信息配置的每个第一CG传输时机可以传输10000比特的数据、传输的画面帧共有50000比特的数据为例。图17B中还示意了画面帧的最晚接收时刻Tlatest2、第二CG传输时机的时刻Tsecond2以及第二CG传输时机对应的重传时间Tretrans2。无线接入网设备在CG传输时机的周期内的前四个第一CG传输时机上共传输了40000比特的数据。对于CG传输时机的周期内的最后一个CG传输时机,以类似与图9描述的原因为例,由于画面帧要求的时延约束的影响,使得Tlatest2–Tsecond2<Tretrans2。此时如果通过调整信息降低了这个第二CG传输时机上的MCS,会导致该第二CG传输时机上可以承载的比特数减少,例如减少到5000比特。因此,此时除了向终端发送包含第二MCS信息的调整信息以外,无线接入网设备还向终端发送第二调度信息/第三调度信息,用于调度CG传输时机以外的时域资源(图中横向条纹所示意的),使得该额外调度的时域资源上能够承载完剩余的5000比特。由于第二CG传输时机上MCS的降低,可以提升这个第二CG传输时机上数据传输的可靠性,降低这个第二CG传输时机上传输数据的重传概率,以尽可能避免需要重传但无法在规定时间内完成重传而导致的整个画面帧的接收失败。
在方法1500中,可选地,还包括:无线接入网设备向终端发送CG去激活信息,该CG去激活信息用于去激活CG的配置。终端接收CG去激活信息,并基于该CG去激活信息停止/暂停在CG传输时机上的上行数据发送。CG去激活信息可包含在DCI中,通过PDCCH承载。
