Description

一种小区搜索方法及装置、终端 技术领域
本申请实施例涉及移动通信技术领域,具体涉及一种小区搜索方法及装置、终端。
背景技术
为了满足人们对业务的速率、延迟、高速移动性、能效的追求,以及未来生活中业务的多样性、复杂性,第三代合作伙伴计划(3GPP,3rd Generation Partnership Project)国际标准组织开始研发第五代(5G,5 thGeneration)移动通信技术。
5G移动通信技术的空口部分称为新空口(NR,New Radio),在NR早期部署时,完整的NR覆盖很难达到,所以典型的网络覆盖是长期演进(LTE,Long Term Evolution)覆盖和NR覆盖的结合。此外,为了保护移动运营商前期在LTE上的投资,提出了LTE和NR之间的紧耦合(tight interworking)工作模式。当然,NR小区也可以独立部署。
在NR中,用户设备(UE,User Equipment)的功率等级一般默认为23dBm,为了能够让小区边缘或者信道条件差的环境能够有良好的上行覆盖,提出了26dBm的高功率等级。高功率等级的UE是可以提高上行覆盖,但是也带来的UE的费电和网络的上行干扰问题。

本发明实施例的技术方案主要应用于5G移动通信系统,当然,本发明实施例的技术方案并不局限于5G移动通信系统,还可以应用于其他类型的移动通信系统。以下对5G移动通信系统中的主要应用场景进行说明:
1)eMBB场景:eMBB以用户获得多媒体内容、服务和数据为目标,其业务需求增长十分迅速。由于eMBB可能部署在不同的场景中,例如室内、市区、农村等,其业务能力和需求的差别也比较大,所以必须结合具体的部署场景对业务进行分析。
2)URLLC场景:URLLC的典型应用包括:工业自动化、电力自动化、远程医疗操作、交通安全保障等。
3)mMTC场景:URLLC的典型特点包括:高连接密度、小数据量、时延不敏感业务、模块的低成本和长使用寿命等。
在NR中,终端的功率等级一般默认为23dBm,为了能够让小区边缘或者信道条件差的环境能够有良好的上行覆盖,终端支持26dBm的高功率等级。目前UE支持高功率等级是UE可选的特性,且只在4个频段(band)上支持高功率等级,其他情况都支持默认的功率等级,即23dBm功率等级。
图2为本申请实施例提供的小区搜索方法的流程示意图一,如图2所示,所述小区搜索方法包括以下步骤:
步骤201:终端接收网络设备发送的第一指示信息,所述第一指示信息用于指示所述终端在当前服务小区是否能够使用第二功率等级。
本申请实施例中,所述终端可以是手机、平板电脑、笔记本电脑、台式机等任意可 以与网络进行通信的设备。
本申请实施例中,所述终端的功率等级对应一个功率值,例如默认功率等级为23dBm,高功率等级为26dBm。
本申请实施例中,所述终端在当前服务小区所在的频段上支持第一功率等级和第二功率等级,所述第一功率等级小于所述第二功率等级,举个例子:UE在当前服务小区所在的band上即支持23dBm功率等级也支持26dBm功率等级。
本申请实施例中,终端可以通过网络侧的系统广播消息获取第一指示信息,所述第一指示信息用于指示所述终端在当前服务小区是否能够使用第二功率等级。例如:所述第一指示信息用于指示所述终端在当前服务小区是否能够使用26dBm功率等级。
步骤202:如果所述第一指示信息指示所述终端在当前服务小区能够使用所述第二功率等级,则所述终端优先采用第一功率等级搜索目标小区,其中,所述第一功率等级小于所述第二功率等级。
本申请实施例中,如果所述第一指示信息指示所述终端在当前服务小区能够使用所述第二功率等级,则:在小区重选过程或者小区选择过程中,所述终端优先采用第一功率等级搜索目标小区,进一步,如果所述终端采用所述第一功率等级未搜索到满足小区选择准则的目标小区,则:所述终端采用所述第二功率等级搜索目标小区;如果所述终端采用所述第二功率等级未搜索到满足小区选择准则的目标小区,则:所述终端采用所述第一功率等级或者所述第二功率等级搜索可接受小区进行驻留。
上述方案中,如果所述终端采用所述第一功率等级搜索到满足小区选择准则的目标小区,则:所述终端驻留到所述目标小区;或者,如果所述终端采用所述第二功率等级搜索到满足小区选择准则的目标小区,则:所述终端驻留到所述目标小区。
举个例子,在小区选择过程中,终端采用23dBm功率等级搜索目标小区,如果搜索到满足小区选择准则的目标小区,则驻留到该目标小区,如果未搜索满足小区选择准则的目标小区,则采用26dBm功率等级搜索目标小区。
这里,小区选择准则包括S准则。
图3为本申请实施例提供的小区搜索方法的流程示意图二,如图3所示,所述小区搜索方法包括以下步骤:
步骤301:终端采用第一功率等级或者第二功率等级进行第一类小区的搜索,所述第一类小区的频率优先级大于当前服务小区的频率优先级,所述第一功率等级小于所述第二功率等级。
本申请实施例中,所述终端可以是手机、平板电脑、笔记本电脑、台式机等任意可以与网络进行通信的设备。
本申请实施例中,所述终端的功率等级对应一个功率值,例如默认功率等级为23dBm,高功率等级为26dBm。
本申请实施例中,所述终端在当前服务小区所在的频段上支持第一功率等级和第二功率等级,所述第一功率等级小于所述第二功率等级,举个例子:UE在当前服务小区所在的band上即支持23dBm功率等级也支持26dBm功率等级。
本申请实施例中,所述方法还包括:所述终端接收网络设备发送的第二指示信息,所述第二指示信息用于指示所述终端是否能够使用第二功率等级进行所述第一类小区的搜索;其中,如果所述第二指示信息指示所述终端能够使用第二功率等级进行所述第一类小区的搜索,则所述终端执行所述采用第一功率等级或者第二功率等级进行第一类小区的搜索的操作。这里,所述第一指示信息可以是网络侧的系统广播消息。
本申请实施例中,所述终端执行所述采用第一功率等级或者第二功率等级进行第一类小区的搜索的操作,可以有如下两种实现方式:
1)所述终端采用第一功率等级进行第一类小区的搜索;如果采用所述第一功率等级未搜索到第一类小区,则所述终端采用第二功率等级进行第一类小区的搜索。
这里,第一类小区是指高优先级小区,高优先级小区的频率优先级大于当前服务小区的频率优先级。举个例子,UE首先按照23dBm功率等级进行高优先级小区搜索,如果找不到,则按照26dBm功率等级进行高优先级小区搜索,如果找到就驻留。
2)所述终端直接采用第二功率等级进行第一类小区的搜索。
举个例子,UE直接采用26dBm功率等级进行高优先级小区搜索,如果找到就驻留。
在一实施方式中,如果所述终端采用所述第二功率等级搜索到第一类小区,则所述终端驻留在所述第一类小区,并采用所述第一功率等级搜索目标小区。进一步,按照第一时间间隔采用所述第一功率等级搜索目标小区,其中,所述第一时间间隔为预定义的或者系统广播配置的。
举个例子,如果UE按照26dBm功率等级搜索到小区并驻留,则UE按照一定时间间隔以23dBm功率等级搜索合适小区并触发小区重选。该时间间隔可以协议规定或者系统广播配置。
上述方案中,如果所述终端采用所述第二功率等级才能够搜索到第一类小区,则 所述终端在触发随机接入过程时,
通过第一前导码或者第一PRACH资源来指示所述终端当前使用的功率等级;或者,
通过MSG3中的比特位来指示所述终端当前使用的功率等级;或者,
通过用于发送MSG3的上行传输资源来指示所述终端当前使用的功率等级。
举个例子:如果UE按照26dBm功率等级才可以驻留当前服务小区,则当UE发起RRC连接建立触发随机接入过程时,通过如下情况指示网络侧终端当前使用的功率等级:
1)通过预留专用的preamble码或者PRACH资源来指示终端当前使用的功率等级;
2)通过MSG3中一个bit指示位来指示终端当前使用的功率等级,例如1表示23dBm功率等级,0表示26dBm功率等级。
3)网络侧分配2个用于传输MSG3的UL Grant,一个UL Grant对应26dBm功率等级,另一个UL Grant对应23dBm功率等级,通过UE选择其中一个UL Grant发送上行MSG3来指示终端当前使用的功率等级。
基于此,网络侧知道UE当前的功率等级后就可以调度正确的调度信息给UE。

接收单元401,用于接收网络设备发送的第一指示信息,所述第一指示信息用于指示所述终端在当前服务小区是否能够使用第二功率等级;
搜索单元402,用于如果所述第一指示信息指示所述终端在当前服务小区能够使用所述第二功率等级,则优先采用第一功率等级搜索目标小区,其中,所述第一功率等级小于所述第二功率等级。
在一实施方式中,在小区重选过程中或者小区选择过程中,如果所述搜索单元402采用所述第一功率等级未搜索到满足小区选择准则的目标小区,则:所述搜索单元402采用所述第二功率等级搜索目标小区;如果所述搜索单元402采用所述第二功率等级未搜索到满足小区选择准则的目标小区,则:所述搜索单元402采用所述第一功率等级或者所述第二功率等级搜索可接受小区进行驻留。
