相关申请的交叉引用
本申请主张在2018年5月17日在中国提交的中国专利申请号No.201810474321.3的优先权以及在2018年8月8日在中国提交的中国专利申请号No.201810896769.4的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,特别是指一种信息上报方法、数据传输方法、用户设备及网络侧设备。
背景技术
窄带物联网(Narrow Band Internet of Things,NB-IOT)系统中,用户设备(User Equipment,UE)根据参考信号接收功率(Reference Signal Receiving Power,RSRP)确定覆盖范围(有三种覆盖范围:正常覆盖,扩展覆盖和极限覆盖),并根据对应的覆盖范围确定发送上行数据的重传次数(Msg1)。网络侧设备根据用户设备发送上行数据采用的重传次数获知UE所处的覆盖范围,并配置相应的重传次数发送下行数据(Msg2)。
由于RSRP不能反映UE的受干扰情况,采用的重传次数存在不能满足数据正确传输的可能。比如,用户设备根据RSRP确定采用的上行重传次数为64,网络侧设备也会相应的采用重传次数进行下行数据传输(比如,重传次数=64)。但如果用户设备受到的干扰较为严重,重传次数64很可能导致用户设备无法正确解调下行数据,影响通信系统性能。

本公开的技术方案中,用户设备采用隐性上报、和/或显性上报,和/或隐性上报+显性上报等方式向网络侧设备上报重传次数信息。
关于显性上报方式,用户设备通过信令中的比特承载重传次数或重传次数范围。具体地,有如下两种场景,每种场景下有几种上报方式:
场景一:用户设备上报给网络侧设备的重传次数信息通过2比特承载
方式一:用户设备上报给网络侧设备下行解调需要的重传次数,用户设备上报的信令内容通过2比特承载。
其中,网络侧设备事先通过无线资源控制(Radio Resource Control,RRC)信令通知用户设备重传次数与比特信息的映射关系,用户设备根据自身的信道情况(SINR)确定解调下行数据需要的重传次数。用户设备根据网络侧设备下发的重传次数与比特信息的映射关系,将需要的重传次数上报给网络侧设备。
具体地,本实施例的技术方案包括以下步骤:
步骤一:网络侧设备通过RRC信令通知用户设备重传次数与比特信息的映射关系(例如,11对应重传次数16,10对应重传次数32;01对应重传次数64;00预留);
步骤二:用户设备根据自身的信道情况(SINR)确定下行解调需要的重传次数(例如,用户设备完成下行解调需要的重传次数是64);
步骤三:用户设备通过信令将重传次数上报给网络侧设备(例如:用户设备上报的信令内容是01,则代表需要的重传次数是64)。
方式二:
用户设备上报网络侧设备下行解调需要的重传次数信息。上报的信息内容是:用户设备完成下行数据解调需要的重传次数与发送Msg1采用的重传 次数的倍数关系,具体有如下几种上报内容:
上报内容1:用户设备数据解调需要的重传次数是Msg1采用的重传次数范围的2倍(或1/2);
上报内容2:用户设备数据解调需要的重传次数是Msg1采用的重传次数范围的4倍(或1/4);
上报内容3:用户设备数据解调需要的重传次数是Msg1采用的重传次数范围8倍(或1/8);
上报内容通过2比特指示。例如,11对应上报内容1;10对应上报内容2;01对应上报内容3;00预留。
方式三:
用户设备上报网络侧设备下行解调需要的重传次数信息。上报的信息内容是:用户设备完成下行数据解调需要的重传次数与发送Msg1采用的重传次数的大小关系,具体有如下几种上报内容:
上报内容1:用户设备数据解调需要的重传次数小于Msg1采用的重传次数范围,此时重传次数仍然属于根据RSRP确定的覆盖范围(例如,用户设备根据RSRP判断当前处于的覆盖范围是正常覆盖,正常覆盖对应的重传次数为{1,2,4,8},用户设备发送Msg1采用的重传次数是8,但是实际用户设备可以根据更小的重传次数完成数据接收,比如重传次数=4);
上报内容2:用户设备数据解调需要的重传次数大于Msg1采用的重传次数范围,此时重传次数仍然属于根据RSRP确定的覆盖范围;(例如,用户设备根据RSRP判断当前处于覆盖范围是扩展覆盖,扩展覆盖对应的重传次数为{16,32,64,128},用户设备发送Msg1采用的重传次数是32,但是实际用户设备需要更大的重传次数才可以完成数据接收,比如重传次数=64);
上报内容3:用户设备数据解调需要的重传次数大于Msg1采用的重传次数范围,此时重传次数超过根据RSRP确定的覆盖范围(例如,用户设备根据RSRP判断当前处于覆盖范围是扩展覆盖,扩展覆盖对应的重传次数为{16,32,64,128},但由于较强干扰的存在,用户设备成功完成数据解调需要的重传次数是256,对于这种场景,用户设备需要通过信令上报网络);
上报内容通过2比特指示。例如,11对应上报内容1;10对应上报内容 2;01对应上报内容3;00预留。
具体地,本实施例的技术方案包括以下步骤:
步骤一:用户设备根据接收信号强度和受干扰情况(SINR),确定数据解调需要的重传次数;
步骤二:用户设备通过信令上报解调需要的重传次数与发送Msg1采用的重传次数的大小关系,该信令内容通过2比特承载;
步骤三:网络侧设备确定发送下行数据采用的重传次数。
方式四:用户设备上报网络侧设备重传次数范围,用户设备通过下行信道质量(SINR)确定完成数据接收需要的重传次数范围。
上报内容通过2比特指示。例如,11对应重传次数范围1,该重传次数范围内的数据解调需要的解调门限是SINR≥X;10对应重传次数范围2,该重传次数范围内的数据解调需要的解调门限是Y≤SINR<X;01对应重传次数范围3,该重传次数范围内的解调门限是SINR≤Y。
具体地,本实施例的技术方案包括以下步骤:
步骤一:用户设备根据接收信号强度和受干扰情况(SINR),确定解调需要的重传次数范围;
如果用户设备解调门限SINR≥X,那么用户设备解调需要的重传次数属于重传次数范围1;
如果用户设备解调门限Y≤SINR<X,那么用户设备解调需要的重传次数属于重传次数范围2;
如果用户设备解调门限SINR≤Y,那么用户设备解调需要的重传次数属于重传次数范围3。
步骤二:用户设备通过信令上报网络侧设备下行解调需要的重传次数范围。该信令内容通过2比特承载;
步骤三:网络侧设备确定发送下行数据采用的重传次数。
方式五:
用户设备上报网络侧设备实际所处的覆盖范围,用户设备通过下行信道质量(SINR)确定实际所处的覆盖范围(包括:正常覆盖,扩展覆盖,极限覆盖)。
上报内容通过2比特指示。例如,11对应极限覆盖;10对应扩展覆盖;01对应正常覆盖。
如果SINR≥X,那么用户设备处于正常覆盖;如果Y≤SINR<X,那么用户设备处于极限覆盖;如果SINR≤Y,那么用户设备处于扩展覆盖。X和Y是SINR门限,用于判断用户设备所处的覆盖范围。
具体地,本实施例的技术方案包括以下步骤:
步骤一:用户设备根据接收信号强度和受干扰情况(SINR),确定所处的覆盖范围(该覆盖范围可能与通过RSRP确定的覆盖范围不同);
如果SINR≥X,那么用户设备处于正常覆盖;
如果Y≤SINR<X,那么用户设备处于扩展覆盖;
如果SINR≤Y,那么用户设备处于极限覆盖。
步骤二:用户设备通过信令上报网络侧设备所处的覆盖范围。该信令内容通过2比特承载;
步骤三:网络侧设备确定发送下行数据采用的重传次数。
方式六:
在只有2比特承载用户设备上报给网络侧设备的重传次数,如果无法确定比特信息与重传次数的对应关系,协议明确规定在此场景用户设备不上报重传次数信息。
场景二:用户设备上报给网络侧设备的重传次数信息通过4比特承载
方式一:
用户设备上报网络侧设备下行解调需要的重传次数,用户设备通过下行信道质量(SINR)确定解调需要的重传次数。
重传次数一共有12种选项,需要4比特指示。例如,1111对应的重传次数=2048,1110对应的重传次数=1024,以此类推。
具体地,本实施例的技术方案包括以下步骤:
步骤一:用户设备根据接收信号强度和受干扰情况(SINR),确定数据解调需要的重传次数;
步骤二:用户设备通过信令上报网络侧设备重传次数。该信令内容通过4比特承载;
步骤三:网络侧设备确定发送下行数据采用的重传次数。
另外,上述几种方式中提到的比特信息与重传次数/重传次数范围/用户设备所处的覆盖范围/与发送MSG1采用的重传次数的大小关系的映射关系可以通过如下方法在用户设备与网络侧设备之间实现一致:
方法一:比特信息与重传次数/重传次数范围/用户设备所处的覆盖范围的映射关系通过系统消息下发(比如,系统信息块1(System Information Block1,SIB1));
方法二:比特信息与重传次数/重传次数范围/用户设备所处的覆盖范围的映射关系固定写入标准中。
关于隐性上报,用户设备通过发送上行数据(比如Msg 3)采用的加扰方式、调制编码方式等来隐性的指示重传次数或者重传次数范围。
关于显性+隐性上报,用户设备通过发送上行数据(比如Msg 3)采用的加扰方式、调制编码方式等来隐性的指示部分比特,同时结合上报内容承载的指示重传次数/重传次数范围的比特。
