请参考图1,其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示,无线通信系统是基于蜂窝移动通信技术的通信系统,该无线通信系统可以包括:若干个终端11以及若干个基站12。
其中,终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,终端11可以是物联网终端,如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机,例如,可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如,站(Station,STA)、订户单元(subscriber unit)、订户站(subscriber station)、移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment,UE)。或者,终端11也可以是无人飞行器的设备。或者,终端11也可以是车载设备,比如,可以是具有无线通信功能的行车电脑,或者是外接行车 电脑的无线通信设备。或者,终端11也可以是路边设备,比如,可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中,该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication,4G)系统,又称长期演进(Long Term Evolution,LTE)系统;或者,该无线通信系统也可以是5G系统,又称新空口(new radio,NR)系统或5G NR系统。或者,该无线通信系统也可以是5G系统的再下一代系统。其中,5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network,新一代无线接入网)。或者,MTC系统。
其中,基站12可以是4G系统中采用的演进型基站(eNB)。或者,基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时,通常包括集中单元(central unit,CU)和至少两个分布单元(distributed unit,DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层、无线链路层控制协议(Radio Link Control,RLC)层、媒体访问控制(Media Access Control,MAC)层的协议栈;分布单元中设置有物理(Physical,PHY)层协议栈,本公开实施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中,该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口;或者,该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口,比如该无线空口是新空口;或者,该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中,终端11之间还可以建立E2E(End to End,端到端)连接。比如车联网通信(vehicle to everything,V2X)中的V2V(vehicle to vehicle,车对车)通信、V2I(vehicle to Infrastructure,车对路边设备)通 信和V2P(vehicle to pedestrian,车对人)通信等场景。
在一些实施例中,上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中,网络管理设备13可以是无线通信系统中的核心网设备,比如,该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core,EPC)中的移动性管理实体(Mobility Management Entity,MME)。或者,该网络管理设备也可以是其它的核心网设备,比如服务网关(Serving GateWay,SGW)、公用数据网网关(Public Data Network GateWay,PGW)、策略与计费规则功能单元(Policy and Charging Rules Function,PCRF)或者归属签约用户服务器(Home Subscriber Server,HSS)等。对于网络管理设备13的实现形态,本公开实施例不做限定。
本公开实施例涉及的执行主体包括但不限于:采用5G NR技术进行通信的用户设备和基站等。
本公开实施例的一种应用场景为,如果用户设备的接收机带宽不足以同时覆盖本小区的服务频点与待测相邻小区的服务频点,用户设备可以以一定的测量间隔(Measurement Gap),对相邻小区的参考信号等进行测量。在用户设备对待测相邻小区进行无线信号测量的测量间隔内,用户设备在服务小区进行的正常数据业务收发以及可能的同频测量将中断。在测量间隔结束之后,用户设备将回到服务小区的频点,继续正常的数据业务的收发和可能的同频测量。
如果用户设备的接收机带宽不足以同时覆盖本小区的服务频点与待测小区的服务频点,在SMTC配置的持续时段上,则用户设备与服务小区进行的正常数据业务收发将中断,进行邻小区SSB的监听。在持续时段结束之后,用户设备将回到服务小区的频点,继续正常的数据业务的收发等。
在5G NR中某些业务类型要求低时延,例如超高可靠低时延通信 (URLLC,Ultra Reliable and Low Latency Communication)业务类型。该类业务通常要求发射端在有待传数据时能够尽快获得传输资源,减少业务在发射端缓存中等待的时延,以此降低空口传输时延。当用户设备在测量间隔或/SMTC持续时段内对异频信号进行测量时,用户设备的接收机将不能接收本服务小区的下行信息,如此,使得数据传输出现时延。
如图2所示,本示例性实施例提供一种数据传输方法,可以应用于无线通信的用户设备中,该方法包括:
步骤201:在测量间隔的起始时刻之前的第一时长内,接收DCI;
步骤202:响应于确定DCI调度预定业务传输,启动第一定时器;
步骤203:在第一定时器的定时时长内,保持与服务小区的下行链路通信,其中,下行链路通信包括:传输预定业务。
测量间隔可以是由基站为用户设备配置的周期性的用于进行异频信号测量的测量时段。如果用户设备的接收机带宽不足以同时覆盖服务小区信号频点与异频小区信号频点,用户设备无法同时进行异频小区的异频信号测量和服务小区的数据传输。测量间隔期间用户设备与服务小区进行的正常数据业务收发将中断。从而导致下行数据传输的时延。在测量间隔结束之后,用户设备将回到服务小区的频点,继续正常的数据业务的收发和可能的同频测量。。
异频信号可以是与用户设备当前所在服务小区的中心频率不同的信号;也可以是与用户设备当前占用带宽部分(BWP,Band Width Part)不同的其他BWP的异频小区的信号等;还可以是在SSB测量中,中心频率不同或子载波间隔(SCS,Sub-Carrier Space)不同的异频小区的信号等。异频信号测量可以是对异频信号进行信号质量测量或对异频信号的监听等。
这里,第一时长可以根据预定业务的调度间隔等确定。第一时长可以大于或等于预定业务的两个传输资源的时间间隔。这样在第一时长内,如 果基站正在调度该预定业务,较大可能会出现一次针对针对预定业务的调度。这样用户设备就能判断将会有持续的预定业务的调度。第一时长也不能设置的过长。否则用户设备需要对很多的DCI都启动第一定时器,会增大用户设备的负担。在第一时长内的DCI可以设置定时器,在接收DCI之后的第一定时器定时时长内保持与服务小区的下行链路通信。如此,传输资源与测量间隔可能发生重叠的预定业务可以设置第一定时器,在定时时长内能进行业务数据的传输,减少预定业务传输时延。
预定业务,可以是具有较高优先级的业务,可以是要求较短时延的下行数据业务,如URLLC业务数据。基站可以下发DCI调度预定业务,并由用户设备接收该DCI。这里,可以使用物理层下行控制信息指示调度的下行业务是否为高优先级业务,如果是,则确定该业务为预定业务。
保持与服务小区的下行链路通信可以包括:传输预定业务。也可以包括:用户设备通过下行链路接收服务小区向用户设备发送的下行链路信号,或用户设备监听下行链路上来自服务小区的下行链路信号等。下行链路信号包括但不限于服务小区向用户设备发送的控制指令和下行数据等。
类似地,基站保持与用户设备的下行链路通信可以包括:传输预定业务。也可以包括:服务小区在需要时通过下行链路向用户设备发送的下行链路信号,或服务小区保持与用户设备的下行链路连接。
这里,当用户设备确定DCI用于调度预定业务传输时,用户设备可以通过设置第一定时器方式设置定时时长,在第一定时器定时时长内保持与服务小区的下行链路通信。第一定时器定时时长可以根据用户设备对DCI进行解析的时长、以及预定业务的传输资源时长等确定。可以确保在第一定时器定时时长内,用户设备可以完成对该预定业务数据的接收。在第一定时器定时时长内用户设备不进行异频信号的测量,因此,在第一定时器定时时长内,业务数据的传输可以不受异频信号测量的影响,减小业务数 据的传输的时延。
当基站确定DCI用于调度预定业务传输时,基站可以通过设置第二定时器方式设置定时时长,在第二定时器定时时长内保持与用户设备的下行链路通信。第二定时器定时时长可以根据用户设备对DCI进行解析的时长、以及预定业务的传输资源时长等确定。可以确保在第二定时器定时时长内,用户设备可以完成对该预定业务数据的接收。在第二定时器定时时长内用户设备不进行异频信号的测量。第一定时器可以和第二定时器保持同步状态,如此可以保持用户设备和基站同时保持与对方的下行链路通信。
如图3所示,用户设备在t0时刻接收到用于调度采用第一优先级的PDSCH资源传输的下行数据的DCI1,t0位于测量间隔之前的第一时长T1内,用户设备在t0时刻启动第一定时器,基站在t0时刻启动第二定时器,第一定时器和第二定时器的定时时长可以相同。t0至t1时刻为第一定时器和第二定时器的定时时长。在第一定时器定时时长,即第二定时器定时时长内用户设备和基站保持下行链路通信。如果两个定时器定时时长内有与测量间隔重叠的时间段,在重叠时间端内,用户设备和基站保持下行链路通信进行下行数据的传输。
如图3所示,用户设备在t4时刻接收到用于调度采用第一优先级的PDSCH资源传输的预定业务的DCI2,t4位于测量间隔之前的第一时长T1之前,因此,可以不针对DCI2设置定时器。
如此,在第一定时器定时时长内,用户设备和基站可以不受异频信号测量的影响,完成预定业务的传输,减少由于进行异频信号测量而停止预定业务传输的情况,减少预定业务的传输时延,满足低时延业务传输的需求。
在一个实施例中,数据传输方法还可以包括:响应于确定在第一定时器的定时时长内接收到的下一个DCI,并且确定确定该DCI调度预定业务 传输,重启第一定时器。如果在第一定时器的定时时长内,用户设备继续收到基站调度预定业务的下一个DCI,则用户设备和基站可以针对该DCI重新对第一定时器进行计时。在接收该DCI之后的第一定时器定时时长内保持与服务小区的下行链路通信。
示例性的,如图4所示,用户设备在t0时间点接收到DCI1,并采用第一定时器进行计时,第一定时器定时时长内的t5时间点,用户设备接收到DCI3,则用户设备可以重置第一定时器,以确保DCI3调度的下行数据可以不受测量间隔影响,完成传输。由于第二次计时的结束时间点晚于第一次计时的结束时间点,因此,DCI1调度的下行数据同样可以不受测量间隔影响,完成传输。
在一个实施例中,数据传输方法还可以包括:响应于确定第一定时器停止定时时刻在测量间隔内,并且还未达到测量间隔的结束时刻,在第一定时器停止定时时刻和测量间隔的结束时刻之间进行异频信号测量。
如图5所示,第一定时器停止定时时刻为t1,测量间隔的结束时刻为t7,t1位于测量间隔内,在t1到t7之间仍然属于测量间隔,因此,用户设备可以在t1到t7之间进行异频信号测量。
如此,可以对测量间隔的剩余时间进行异频信号测量,提高测量间隔的剩余时间的利用率。
在一个实施例中,响应于确定第一定时器停止定时时刻在测量间隔内,并且还未达到测量间隔的结束时刻,在第一定时器停止定时时刻和测量间隔的结束时刻之间进行异频信号测量,包括:响应于确定第一定时器停止定时时刻与测量间隔的结束时刻的时间差大于第二时长,在第一定时器停止定时时刻和测量间隔的结束时刻之间进行异频信号测量。
由于用户设备接收机在服务小区信号频点和异频小区信号频点之间相互切换时,需要一定的切换时间,这是用户设备用于一次频点切换的时长。 因此,当第一定时时长的结束时间点与测量间隔的结束时间点小于两倍的该异频切换时间时,用户设备在测量间隔的结束后无法及时切换回服务小区频点,即无法及时切换回服务小区进行通信,由此导致无用的切换操作,甚至延误在服务小区的下行链路通信。因此,尽可能的避免以上情况,基站可以至少基于切换时间来配置第二时长。第二时长可以大于或等于两倍的该异频切换时间。在一个具体实施例中,基站可以基于除用户设备的频点切换时间之外的其他因素来配置该时长阈值。例如,该其他因素包括:系统的资源配置状态、基站的全局配置、信道质量等。第二时长大于或等于两倍的该异频切换时间,为用户设备是否可以进行两次异频切换提供了衡量基础。一方面,可以有效利用测量间隔的剩余时段进行异频信号测量,另一方面可以减少用户设备无法及时切换回服务小区的情况,减少无效异频切换。
如果第一定时时长的结束时间点距离测量间隔的结束时间点大于第二时长,则用户设备可以在第一定时时长结束后进行异频信号测量,直到在测量间隔结束时间点切换回服务小区。
示例性的,如图5所示,第一定时时长的结束时间点t1位于用户设备进行异频信号测量的测量间隔之内,并且t1到测量间隔的结束时间点t7大于第二时长T2,如果在t1到t7之间进行异频信号测量,由于用户设备需要进行两次频点切换,考虑到异频信号测量占用的时间以及用户设备的异频切换时长,用户设备可以在t7时间点起切换到服务小区频点进行下行链路通信,因此,则用户设备在t1至t7时间段内可以进行异频信号测量。
如此,可以对测量间隔的剩余时间进行异频信号测量,提高测量间隔的剩余时间的利用率。
在一个实施例中,数据传输方法还可以包括:响应于确定第一定时器停止定时时刻与测量间隔的结束时刻的时间差小于或等于第二时长时,在 第一定时器停止定时时刻和测量间隔的结束时刻之间保持与服务小区的下行链路通信。
当第一定时时长的结束时间点与测量间隔的结束时间点小于或等于第二时长时,用户设备在测量间隔的结束后无法及时切换回服务小区频点,即无法及时切换回服务小区进行通信,由此导致无用的切换操作,甚至延误在服务小区的下行链路通信。
如果第一定时时长的结束时间点距离测量间隔的结束时间点小于等于第二时长,用户设备可以保持与服务小区的下行链路通信。第二时长可以由基站通过高层信令设置。
示例性的,如图5所示,第一定时时长的结束时间点t1位于用户设备进行异频信号测量的测量间隔之内,并且t1到测量间隔的结束时间点t7小于或等于第二时长T2,如果在t1到t7之间进行异频信号测量,由于用户设备需要进行两次频点切换,考虑到异频信号测量占用的时间以及用户设备的异频切换时长,可以确定用户设备无法在t7时间点起切换到服务小区频点进行下行链路通信,因此,则用户设备在t1至t7时间段内可以保持在服务小区上接收下行信息,不进行异频信号测量。
如此,可以减少在测量间隔结束后无法及时切换到服务小区频点进行下行链路通信的情况。提高传输时段下行数据接收可靠性。同时,可以减少无效的频点切换。
在一个实施例中,第二时长大于或等于用户设备进行两次异频切换的时长。
用户设备从服务小区接收的下行数据切换到在异频小区频点进行异频信号测量,再切换到服务小区进行的下行链路通信,用户设备接收机需要从服务小区信号频点转换到异频小区频点并再次切换到服务小区频点,用户设备需要对接收机进行配置等处理。因此,第二时长可以大于或等于两 倍的用户设备的异频切换时长。
在一个实施例中,第一定时器的定时时长大于或等于解析DCI的时长与预定业务的传输资源时长中的较大者。
用户设备从接收DCI到完成预定业务的传输,所需的时间可以包括以下之一:解析DCI的时间;预定业务的传输时间。因此,可以设置第一定时时长大于或等于解析DCI的时长与预定业务的传输资源时长中的较大者。
如此,可以是用户设备可以在第一定时时长内完成预定业务的传输。
在一个实施例中,第一时长大于或等于预定业务的两个传输资源的时间间隔。
第一时长可以大于或等于预定业务的两个传输资源的时间间隔,这样在第一时长内,如果基站正在调度该预定业务,较大可能会出现一次针对预定业务的调度。这样用户设备就能判断将会有持续的预定业务的调度。第一时长也不能设置的过长。否则用户设备需要对很多的DCI都启动第一定时器,会增大用户设备的负担。在第一时长内的DCI可以设置定时器,在接收DCI之后的第一定时器定时时长内保持与服务小区的下行链路通信。
在一个实施例中,数据传输方法还可以包括:
接收指示信息,其中,指示信息,用于指示第一时长和/或第一定时器的定时时长。
这里,基站可以根据自身配置的预定业务的PDSCH资源周期等确定第一时长和/或第一定时器的定时时长,并通过指示信息发送给用户设备。
在一个实施例中,异频信号测量包括:
在异频小区上进行的参考信号测量;
和/或,
在异频小区上进行的同步信号块SSB监听。
用户设备在异频小区上进行异频信号测量的测量间隔,包括:用户设备在异频小区上进行参考信号测量的测量间隔;和/或,用户设备在异频小区上进行同步信号块SSB监听的持续时段。
这里,参考信号测量可以是用户设备进行移动性测量时测量的异频小区的参考信号。用户设备可以间隔性测量异频小区的参考信号。基站可以为用户设备配置周期性的测量间隔。
基站可以为用户设备配置周期性的持续时段用来监听异频小区的SSB。
在一个实施例中,确定DCI调度预定业务传输,包括以下至少之一:
基于DCI中预定信息域的指示信息,确定DCI调度预定业务传输;
基于DCI的格式,确定DCI调度预定业务传输;
基于DCI的循环冗余码校验CRC加扰采用的无线网络临时标识RNTI,确定DCI调度预定业务传输。
用户设备可以通过DCI预定信息域中的指示信息,DCI的格式和/或DCI的CRC加扰使用的RNTI的不同,来判断收到的DCI是否用于调度预定业务的传输。例如:针对预定业务,如URLLC业务数据,可以使用的是一种更紧凑的DCI格式,而采用非预定业务可以使用比特数相对较大的DCI格式。又例如:用于调度URLLC下行数据的DCI的CRC加扰使用的RNTI与调度其他业务使用的RNTI不同。
如此,用户设备可以有效区分调度不同下行数据的DCI,提到DCI区分效率。
在一个实施例中,第一定时器停止定时,包括:
第一定时器在第一定时器超时时停止定时,或,第一定时器在测量间隔的结束时刻停止定时。
这里,第一定时器停止定时条件可以包括:第一定时器超时。也可以是当前测量间隔结束时,第一定时器停止定时。
如图6所示,本示例性实施例提供一种于数据传输方法,可以应用于无线通信的基站中,该方法包括:
步骤601:在测量间隔的起始时刻之前的第一时长内,发送DCI;
步骤602:响应于确定DCI调度预定业务传输,启动第二定时器;
步骤603:在第二定时器的定时时长内,保持与服务小区的下行链路通信,其中,下行链路通信包括:传输预定业务。
测量间隔可以是由基站为用户设备配置的周期性的用于进行异频信号测量的测量时段。如果用户设备的接收机带宽不足以同时覆盖服务小区信号频点与异频小区信号频点,用户设备无法同时进行异频小区的异频信号测量和服务小区的数据传输。测量间隔期间用户设备与服务小区进行的正常数据业务收发将中断。从而导致下行数据传输的时延。在测量间隔结束之后,用户设备将回到服务小区的频点,继续正常的数据业务的收发和可能的同频测量。
异频信号可以是与用户设备当前所在服务小区的中心频率不同的信号;也可以是与用户设备当前占用带宽部分(BWP,Band Width Part)不同的其他BWP的异频小区的信号等;还可以是在SSB测量中,中心频率不同或子载波间隔(SCS,Sub-Carrier Space)不同的异频小区的信号等。异频信号测量可以是对异频信号进行信号质量测量或对异频信号的监听等。
这里,第一时长可以根据预定业务的调度间隔等确定。第一时长可以大于或等于预定业务的两个传输资源的时间间隔。这样在第一时长内,如果基站正在调度该预定业务,较大可能会出现一次针对预定业务的调度。这样用户设备就能判断将会有持续的预定业务的调度。第一时长也不能设置的过长。否则用户设备需要对很多的DCI都启动第一定时器,会增大用 户设备的负担。在第一时长内的DCI可以设置定时器,在接收DCI之后的第一定时器定时时长内保持与服务小区的下行链路通信。如此,传输资源与测量间隔可能发生重叠的预定业务可以设置第一定时器,在定时时长内能进行业务数据的传输,减少预定业务传输时延。
预定业务,可以是具有较高优先级的业务,可以是要求较短时延的下行数据业务,如URLLC业务数据。基站可以下发DCI调度预定业务,并由用户设备接收该DCI。这里,可以使用物理层下行控制信息指示调度的下行业务是否为高优先级业务,如果是,则确定该业务为预定业务。
保持与服务小区的下行链路通信可以包括:传输预定业务。也可以包括:用户设备通过下行链路接收服务小区向用户设备发送的下行链路信号,或用户设备监听下行链路上来自服务小区的下行链路信号等。下行链路信号包括但不限于服务小区向用户设备发送的控制指令和下行数据等。
类似地,基站保持与用户设备的下行链路通信可以包括:传输预定业务。也可以包括:服务小区在需要时通过下行链路向用户设备发送的下行链路信号,或服务小区保持与用户设备的下行链路连接。
这里,当用户设备确定DCI用于调度预定业务传输时,用户设备可以通过设置第一定时器方式设置定时时长,在第一定时器定时时长内保持与服务小区的下行链路通信。第一定时器定时时长可以根据用户设备对DCI进行解析的时长、以及预定业务的传输资源时长等确定。可以确保在第一定时器定时时长内,用户设备可以完成对该预定业务数据的接收。在第一定时器定时时长内用户设备不进行异频信号的测量,因此,在第一定时器定时时长内,业务数据的传输可以不受异频信号测量的影响,减小业务数据的传输的时延。当基站确定DCI用于调度预定业务传输时,基站可以通过设置第二定时器方式设置定时时长,在第二定时器定时时长内保持与用户设备的下行链路通信。第二定时器定时时长可以根据用户设备对DCI进 行解析的时长、以及预定业务的传输资源时长等确定。可以确保在第二定时器定时时长内,用户设备可以完成对该预定业务数据的接收。在第二定时器定时时长内用户设备不进行异频信号的测量。第一定时器可以和第二定时器保持同步状态,如此可以保持用户设备和基站同时保持与对方的下行链路通信。
如图3所示,基站在t0时刻发送用于调度采用第一优先级的PDSCH资源传输的下行数据的DCI1,t0位于测量间隔之前的第一时长T1内,用户设备可以在t0时刻设置第一定时器,基站在t0时刻启动第二定时器,第一定时器和第二定时器的定时时长可以相同。t0至t1时刻为第一定时器和第二定时器的定时时长。在第一定时器定时时长,即第二定时器定时时长内用户设备和基站保持下行链路通信。如果两个定时器定时时长内有与测量间隔重叠的时间段,在重叠时间端内,用户设备和基站保持下行链路通信进行下行数据的传输。
如图3所示,基站在t4时刻发送用于调度采用第一优先级的PDSCH资源传输的预定业务的DCI2,t4位于测量间隔之前的第一时长T1之前,因此,可以不针对DCI2设置定时器。
如此,在第二定时器定时时长内,用户设备和基站可以不受异频信号测量的影响,完成预定业务的传输,减少由于进行异频信号测量而停止预定业务传输的情况,减少预定业务的传输时延,满足低时延业务传输的需求。
在一个实施例中,数据传输方法还包括:
响应于确定第二定时器停止定时时刻在测量间隔内,并且还未达到测量间隔的结束时刻,并且第二定时器停止定时时刻与测量间隔的结束时刻的时间差小于或等于第二时长,在第二定时器停止定时时刻和测量间隔的结束时刻之间保持与用户设备的下行链路通信。
由于用户设备接收机在服务小区信号频点和异频小区信号频点之间相互切换时,需要一定的切换时间,这是用户设备用于一次频点切换的时长。因此,当第二定时时长的结束时间点与测量间隔的结束时间点小于两倍的该异频切换时间时,用户设备在测量间隔的结束后无法及时切换回服务小区频点,即无法及时切换回服务小区进行通信,由此导致无用的切换操作,甚至延误在服务小区的下行链路通信。因此,尽可能的避免以上情况,基站可以至少基于切换时间来配置第二时长。第二时长可以大于或等于两倍的该异频切换时间。在一个具体实施例中,基站可以基于除用户设备的频点切换时间之外的其他因素来配置该时长阈值。例如,该其他因素包括:系统的资源配置状态、基站的全局配置、信道质量等。第二时长大于或等于两倍的该异频切换时间,为用户设备是否可以进行两次异频切换提供了衡量基础。一方面,可以有效利用测量间隔的剩余时段进行异频信号测量,另一方面可以减少用户设备无法及时切换回服务小区的情况,减少无效异频切换。当第二定时时长的结束时间点与测量间隔的结束时间点小于或等于第二时长时,用户设备在测量间隔的结束后无法及时切换回服务小区频点,即无法及时切换回服务小区进行通信,由此导致无用的切换操作,甚至延误在服务小区的下行链路通信。
因此,如果第二定时时长的结束时间点距离测量间隔的结束时间点小于等于第二时长,用户设备可以保持与服务小区的下行链路通信。第二时长可以由基站通过高层信令设置。
在一个实施例中,第二时长大于或等于用户设备进行两次异频切换的时长。
用户设备从服务小区接收的下行数据切换到在异频小区频点进行异频信号测量,再切换到服务小区进行的下行链路通信,用户设备接收机需要从服务小区信号频点转换到异频小区频点并再次切换到服务小区频点,用 户设备需要对接收机进行配置等处理。因此,第二时长可以大于或等于两倍的用户设备的异频切换时长。
在一个实施例中,第二定时器的定时时长大于或等于用户设备解析DCI的时长与预定业务的传输资源时长中的较大者。
用户设备从接收DCI到完成预定业务的传输,所需的时间可以包括以下之一:解析DCI的时间;预定业务的传输时间。因此,可以设置第二定时时长大于或等于解析DCI的时长与预定业务的传输资源时长中的较大者。
如此,可以是用户设备可以在第一定时时长内完成预定业务的传输。
在一个实施例中,第一时长大于或等于预定业务的两个传输资源的时间间隔。
第一时长可以大于或等于预定业务的两个传输资源的时间间隔,这样在第一时长内,如果基站正在调度该预定业务,较大可能会出现一次针对针对预定业务的调度。这样用户设备就能判断将会有持续的预定业务的调度。第一时长也不能设置的过长。否则用户设备需要对很多的DCI都启动第一定时器,会增大用户设备的负担。在第一时长内的DCI可以设置定时器,在接收DCI之后的第一定时器定时时长内保持与服务小区的下行链路通信。
在一个实施例中,数据传输方法还可以包括:
发送指示信息,其中,指示信息,用于指示第一时长和/或第二定时器的定时时长。
这里,基站可以根据自身配置的预定业务的PDSCH资源周期等确定第一时长和/或第一定时器的定时时长,并通过指示信息发送给用户设备。
在一个实施例中,发送DCI,包括以下至少之一:
在DCI的预定信息域内,配置与预定业务对应的指示信息,
和/或,
使用与预定业务对应DCI格式,
和/或,
为DCI配置的循环冗余码校验CRC加扰与预定业务对应的无线网络临时标识RNTI;
发送DCI。
基站可以在DCI预定信息域中设置指示信息来指示DCI用于调度预定业务,用户设备可以通过DCI预定信息域中的指示信息,来判断收到的DCI是否用于调度预定业务的传输。
基站可以采用不同的DCI格式指示DCI所调度的不同的业务,用户设备可以通过DCI的格式来判断收到的DCI是否用于调度预定业务的传输。
基站还可以采用在DCI的CRC加扰中使用的不同的无线网络临时标识(RNTI,Radio Network Tempory Identity)指示DCI所调度的不同的业务,用户设备可以通过RNTI来判断收到的DCI是否用于调度预定业务的传输。
例如:针对预定业务,如URLLC业务数据,可以使用的是一种更紧凑的DCI格式,而采用非预定业务可以使用比特数相对较大的DCI格式。又例如:用于调度URLLC下行数据的DCI的CRC加扰使用的RNTI与调度其他业务使用的RNTI不同。
如此,用户设备可以有效区分调度不同下行数据的DCI,提到DCI区分效率。
以下结合上述任意实施例提供一个具体示例:
用户设备可以通过DCI的格式,或者DCI的CRC加扰使用的RNTI的不同,来判断收到的DCI是用于调度采用第一优先级的PDSCH资源传输的下行数据,还是用于调度采用第二优先级的PDSCH资源传输的下行数据。例如:针对采用第一优先级的PDSCH资源传输的下行数据,如URLLC 业务数据,可以使用的是一种更紧凑的DCI格式,而采用第二优先级的PDSCH资源传输的下行数据可以使用比特数相对较大的DCI格式。又例如:用于调度URLLC下行数据的DCI的CRC加扰使用的RNTI与调度其他业务使用的RNTI不同。
如图7所示,只有在距离当前测量间隔起始时间点T1内,用户设备收到调度URLLC业务的DCI1时,用户设备启动定时器1进行计时。如果是在T1时段之前收到的DCI2,则用户设备不会启动定时器1。
T1和/或定时器1的时长由基站通过高层信令设置。基站可以通过无线资源控制(RRC,Radio Resource Control)层信令、MAC层信令配置T1和/或定时器1的时长。如果在定时器1内,用户设备继续收到基站调度URLLC数据的DCI3,则重新开始定时器1。
定时器1结束的条件:当定时器1超时,或者当前测量间隔结束时,定时器1就结束了。
当定时器1结束时,如果当前的测量间隔还没有结束,则用户设备可以进入测量间隔进行异频信号测量。
考虑到用户设备进行异频测量时,需要进行频点的转换,因而需要一定的转换时延。一种可能的方案是:如果定时器1结束的时刻,距离用户设备当前的测量间隔结束时间点大于T2,则用户设备将在测量间隔剩余时间进行异频信号测量。如果小于T2,则用户设备应该保持在服务小区的频点上接收下行信息。T2的时长由基站通过高层信令设置。
