具体实施方式
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
本申请的说明书和权利要求书中的术语“包括”以及它的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外,说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一,例如A和/或B,表示包含单独A,单独B,以及A和B都存在三种情况。说明书以及权利要求中使用的“一项多项组合”表示至少其中之一,例如A、B和C中的一项多项组合表示包含:单独A,单独B,单独C,A和B,A和C、B和C,以及A、B和C的七种情况。

下面介绍几个技术点:
(1)关于辅助上行载波(Supplementary Uplink carrier,SUL carrier)介绍:
在第五代移动通信(Fifth-generation,5G)系统中,对于1个下行载波可以配置2个上行载波,其中1个为辅助上行载波,该辅助上行载波可以配置给主小区(Primary Cell,PCell)或辅小区(Secondary Cell,SCell)。
(2)关于带宽部分(Bandwidth Part)的介绍:
5G新空口(NR)系统支持最大400MHz系统带宽,远大于LTE最大20MHz的系统带宽,以支持更大的系统与用户吞吐量。然而,支持如此之大的系统带宽对于UE的实现将是一个巨大的挑战,不利于低成本UE的实现。因此,5G NR系统也支持动态灵活的带宽分配,将系统带宽划分成多个带宽 部分,以支持窄带UE,或节能模式的UE的接入。
5G NR系统支持6GHz以上的工作频段,可以为数据传输提供更大的吞吐量。高频信号的波长短,同低频段相比,能够在同样大小的面板上布置更多的天线阵元,利用波束赋形技术形成指向性更强、波瓣更窄的多个波束。5G NR系统通过波束扫描技术,为小区内的UE发送广播信号或系统信息。
下面结合附图介绍本公开的实施例。本公开实施例提供的载波状态的控制方法和设备可以应用于无线通信系统中。该无线通信系统可以为5G移动通信技术的系统(以下均简称为5G系统),参考图1,为本公开实施例提供的一种无线通信系统的架构示意图。如图1所示,该无线通信系统可以包括网络侧设备10和用户设备,例如用户设备记做UE 11,UE 11可以与网络侧设备10通信。在实际应用中上述各个设备之间的连接可以为无线连接,为了方便直观地表示各个设备之间的连接关系,图1中采用实线示意。
需要说明的是,上述通信系统可以包括多个UE,网络侧设备和可以与多个UE通信(传输信令或传输数据)。
本公开实施例提供的网络侧设备可以为基站,该网络侧设备可以为通常所用的基站,也可以为演进型基站(evolved node base station,eNB),还可以为5G系统中的网络侧设备(例如下一代基站(next generation node base station,gNB)或发送和接收点(transmission and reception point,TRP))等设备。
本公开实施例提供的用户设备可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer,UMPC)、上网本或者个人数字助理(Personal Digital Assistant,PDA)等。
为使本公开的目的、技术方案和优点更加清楚,下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
参见图2,图中示出了随机接入方法的流程图,该方法的执行主体为UE,具体步骤如下:
步骤201、从两个或两个以上UL的RACH资源中,确定目标RACH资源;
步骤202、根据所述目标RACH资源进行随机接入。
方式一、根据UL的类型、UL的频点、RACH资源的类型、以及测量性能中的一项或多项组合,从两个或两个以上UL的RACH资源中确定目标RACH资源,该UL的类型包括:辅助UL(Supplementary UL)和正常UL(Normal UL),该测量性能是指UL或BWP的测量性能或正常UL对应的下行载波的测量性能。
在本公开实施例中,测量性能包括至少一项:参考信号接收功率(RSRP)、参考信号接收质量(RSRQ)、信号与干扰加噪声比(SINR)和信道质量指示(CQI),当然并不限于此。
在本公开实施例中,选择低频点可增强覆盖,或者选择当前工作频点相同的频点可以避免UE的射频调整(RF tuning/retuning)。
方式二、根据RACH目的或RACH原因,从两个或两个以上UL的RACH资源中确定目标RACH资源。
例如:根据RACH目的或RACH原因,将两个或两个以上UL的RACH资源中的正常UL或者SUL的RACH资源确定为目标RACH资源;或者根据RACH目的或RACH原因,将两个或两个以上UL的RACH资源中的专用RACH资源确定为目标RACH资源。
上述RACH目的或RACH原因包括但不限于:支持初始空闲态(idle)UE连接到网络;无线资源控制(RRC)重建;切换(Handover);下行数据到达但上行失步;上行数据到达但上行失步;UE从非激活(inactive)态转到激活(active)态;支持辅小区(Scell)的上行同步获取。
这样,UE能够从两个或两个以上UL的RACH资源中,确定目标RACH资源;再根据目标RACH资源进行随机接入,提高随机接入的灵活性。
参见图3,图中示出了随机接入方法的流程图,该方法的执行主体为UE,包括步骤步骤301和302。
步骤301、根据UL类型、UL的频点、RACH资源的类型、以及测量性能中的一项或多项组合,从两个或两个以上UL的RACH资源中确定目标RACH资源;
在本公开实施例中,所述UL的类型包括:辅助UL和正常UL。
在本公开实施例中,该测量性能是指UL或BWP的测量性能或正常UL对应的下行载波的测量性能,该测量性能包括至少一项:参考信号接收功率(RSRP)、参考信号接收质量(RSRQ)、信号与干扰加噪声比(SINR)和信道质量指示(CQI),当然并不限于此。
步骤302、根据所述目标RACH资源进行随机接入。
在本公开实施例中,如果激活的BWP配置了RACH资源,可根据以下原则之一,从两个或两个以上UL的RACH资源中确定目标RACH资源:
原则一、UL的类型为正常上行(正常UL)或者辅助上行(Secondary UL,SUL),即正常UL优先或SUL优先。
以正常UL优先为例:只要正常UL激活的BWP配置有RACH资源,则优先选择正常UL激活的BWP上的RACH资源。
具体地,正常UL激活的BWP配置有专用(Dedicated)或者普通(common)RACH,SUL配置有专用或者普通RACH资源(无论是SUL配置有BWP,且某个BWP上配置有专用或者普通RACH资源,还是SUL没有配置BWP,RACH资源直接在SUL上配置),优先选择正常UL激活的BWP上配置的RACH资源。如果根据正常UL优先的原则从两个或两个以上UL的RACH资源中确定目标RACH资源,能够防止UE经常射频重调(RF Retuning),节省功耗和时延。
以SUL优先为例:如果根据SUL优先的原则从两个或两个以上UL的RACH资源中确定目标RACH资源,能够卸载正常UL上的RACH资源,节省正常UL的资源,降低正常UL的RACH资源冲突的概率。

这样,UE能够从两个或两个以上UL的RACH资源中,确定目标RACH资源;再根据目标RACH资源进行随机接入,提高随机接入的灵活性。
参见图4,图中示出了一种随机接入方法的流程,该方法的执行主体为UE,具体步骤如下:
步骤401、确定随机接入的目标UL和/或目标BWP;
步骤402、根据所述目标UL和/或目标BWP,在RACH过程中切换UL和/或切换BWP。
场景一、在同一次RACH attempt过程中:
根据UL类型、UL的频点、RACH资源的类型、以及测量性能中的一项或多项组合,确定同一次随机接入尝试(RACH attempt)过程的目标UL和/或目标BWP,其中,所述测量性能是指UL或BWP的测量性能或正常UL对应的下行载波的测量性能;或者根据网络侧设备的配置确定同一次RACH attempt过程的目标UL和/或目标BWP。
示例1:UE通过消息1(msg1)发送当前使用的UL,UE根据UL类型、UL的频点、RACH资源的类型、以及测量性能中的一项或多项组合,或者根据系统广播消息或者通过释放消息确定目标UL。
例如:UE从连接态进入idle或者inactive态时,通过释放(release)消息通知UE使用哪个UL进行RACH。

在本公开实施例中,可选地,消息2能够显式指示或隐式指示目标UL,例如,消息2中包含指示目标UL的指示位,或者消息2的格式、时域、频域或波束位置隐式指示目标UL。
场景二、在同一个RACH过程中的RACH preamble重传过程中:
方式一、根据UL类型、UL的频点、RACH资源的类型、以及测量性能中的一项或多项组合,选择UL和/或BWP;根据当前使用的UL和/或BWP,以及选择的UL和/或BWP,确定RACH过程中RACH前导码(Preamble)重传过程的目标UL和/或目标BWP。
方式二、根据网络侧设备的配置,选择UL和/或BWP;根据当前使用的UL和/或BWP,以及选择的UL和/或BWP,确定RACH过程中RACH Preamble重传过程的目标UL和/或目标BWP。
示例1:在每次的RACH preamble重传时,使用当前使用的UL和当前使用的BWP。
即,在RACH Preamble重传时,将当前使用的UL确定为目标UL,或将当前使用的UL和当前使用的BWP确定为目标UL和目标BWP。
具体地,在每次的RACH preamble重传时,按照现有规则对输出功率爬升计数器(POWER_RAMPING_COUNTER)和前导码传输计数器(PREAMBLE_TRANSMISSION_COUNTER)进行累加。
示例2:在RACH Preamble重传时,将当前使用的UL和选择的BWP确定为目标UL和目标BWP。

a、按照现有
规则分别对POWER_RAMPING_COUNTER和PREAMBLE_TRANSMISSION_COUNTER进行累加(例如增加1);
b、POWER_RAMPING_COUNTER进行累加,以及PREAMBLE_TRANSMISSION_COUNTER进行累加;
c、POWER_RAMPING_COUNTER不进行累加,以及PREAMBLE_TRANSMISSION_COUNTER不进行累加;
d、当在目标BWP上进行重传时,与所述目标BWP对应的POWER_RAMPING_COUNTE和/或对应的PREAMBLE_TRANSMISSION_COUNTER进行累加(例如增加1)。
需要说明的是,每个BWP都对应一套RACH过程的计数器POWER_RAMPING_COUNTER和PREAMBLE_TRANSMISSION_COUNTER。
可选地,当切换BWP时,将RACH Preamble重传直接停止,在目标BWP上重新开始RACH Preamble重传;或者
当切换BWP时,将RACH Preamble重传直接挂起,在目标BWP上重新开始RACH Preamble重传;当切换回到之前的BWP时,使用上一次RACHPreamble重传的参数继续RACH Preamble重传。
示例3:在每次的RACH Preamble重传时,使用重新选择的UL和BWP:
即,在RACH Preamble重传时,将选择的UL和选择的BWP确定为目标UL和目标BWP。
可选地,当切换UL时,RACH过程的计数器POWER_RAMPING_COUNTER和PREAMBLE_TRANSMISSION_COUNTER进行以下任意一种方式处理:
a、按照现有规则分别对POWER_RAMPING_COUNTER和PREAMBLE_TRANSMISSION_COUNTER进行累加(例如增加1);
b、POWER_RAMPING_COUNTER不进行累加,以及PREAMBLE_TRANSMISSION_COUNTER进行累加;
c、POWER_RAMPING_COUNTER不进行累加,以及PREAMBLE_TRANSMISSION_COUNTER不进行累加;
d、当在目标UL上重传时,对与所述目标UL对应的POWER_RAMPING_COUNTE和/或PREAMBLE_TRANSMISSION_COUNTER进行累加(例如增加1)。
需要说明的是,每个UL都对应一套RACH过程的计数器POWER_RAMPING_COUNTER和PREAMBLE_TRANSMISSION_COUNTER。
可选地,当切换UL时,将RACH Preamble重传直接停止,在目标UL上重新开始RACH Preamble重传;或者当切换UL时,将RACH Preamble重传直接挂起,在目标UL上重新开始RACH Preamble重传;当切换回到之前的UL时,使用上一次RACH Preamble重传的参数继续RACH Preamble重传。
这样,UE确定随机接入的目标UL和/或目标BWP;再根据目标UL和/或目标BWP,在RACH过程中切换UL和/或切换BWP,提高随机接入的灵活性。
