Description

确定非竞争随机接入资源的方法、网络设备和终端设备 技术领域
本发明实施例涉及通信领域,并且更具体地,涉及确定非竞争随机接入资源的方法、网络设备和终端设备。
背景技术
随着人们对速率、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(The 3rd Generation Partnership Project,3GPP)国际标准组织开始研发第五代移动通信技术(5-Generation,5G)。在新空口(New Radio,NR)早期部署时,完整的NR覆盖很难获取,所以典型的网络覆盖是广域的长期演进(Long Term Evolution,LTE)覆盖和NR的孤岛覆盖模式。而且由于大量的LTE部署在6吉赫(GHz)以下,可用于5G的6GHz以下频谱很少。因此,NR必须研究6GHz以上的频谱应用,而高频段覆盖有限、信号衰落快。
现有技术中,由于终端设备上行功率受限,而且NR的频谱(频率高,传播损失高)的频率又较高,所以上行覆盖会受限,为了提高上行覆盖,利用LTE频谱(相对频率较低)作为辅助上行频谱(即,存在一个辅助上行链路载波),可以提高上行覆盖。
但是,终端设备没有辅助上行链路(SUL)的场景下,非竞争随机接入资源通过无线资源控制(Radio Resource Control,RRC)或者物理下行链路控制信道(Physical Downlink Control Channel,PDCCH)命令(order)形式配置给终端设备,此时只有一个上行载波,所以终端设备很清楚非竞争随机接入资源的配置情况,进而可以正确选择该非竞争随机接入资源发起随机接入过程。

图3是本发明实施例的网络设备的示意性框图。

图5是本发明实施例的终端设备的示意性框图。
图6是本发明实施例的另一终端设备的示意性框图。
具体实施方式
图1是本发明实施例的应用场景的示例。
如图1所示,终端设备可以具有一个下行载波和两个上行载波(如图1 所示,第一上行载波和第二上行载波)。具体的,该第一上行载波和下行载波可以是NR高频带上的载波,该第二上行载波可以是LTE低频带上的载波。应理解,图1所示的终端设备具有两个上行载波仅为示例性描述,本发明实施例不作具体限定。例如,该终端设备也可以支持三个上行载波等等。
应理解,引入第二上行载波的动机是为了提高NR高频带的上行覆盖。
具体地,由于终端设备上行功率受限,而且NR的频谱(频率高,传播损失高)的频率又较高,所以NR的上行覆盖会受限,为了提高上行覆盖,本发明实施例中,提出了一种传输数据的方法。通过利用LTE频谱(相对频率较低)作为辅助上行载波,能够提高上行覆盖效果。
例如,第一上行载波和第二上行载波组合可以类似于LTE中的载波聚合(CA),只是没有配对的下行。即,从频带(band)组合的角度看,第二上行载波是个只有上行没有配对下行的小区,但是它的上行受控于某个下行载波,也就是当配置了第二上行载波,第二上行载波就是一个没有下行的辅助服务小区(SCell),对于第二上行载波的控制依赖于主服务小区(PCell)。
应理解,本发明实施例可以适用于任何包括多个上行的通信系统。例如,该第一通信系统和该第二通信系统可以是各种通信系统,例如:全球移动通讯(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)等。
此外,本发明结合网络设备(该第一网络设备至第四网络设备)和终端设备描述了各个实施例。
其中,网络设备可以指网络侧的任一种用来发送或接收信号的实体。例如,可以是机器类通信(MTC)的用户设备、GSM或CDMA中的基站(Base Transceiver Station,BTS)、WCDMA中的基站(NodeB)、LTE中的演进型基站(Evolutional Node B,eNB或eNodeB)、5G网络中的基站设备等。
终端设备可以是任意终端设备。具体地,终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network)进行通信,也可称为接入终端、用户设备(User Equipment,UE)、用户单元、 用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。例如,可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及5G网络中的终端设备等。
结合非竞争随机接入过程可以发现,在非辅助上行链路(SUL)场景下,非竞争随机接入资源通过RRC或者PDCCH order形式配置给UE,此时只有一个上行载波,所以UE很清楚非竞争随机接入资源的配置情况,进而可以正确选择该非竞争随机接入资源发起随机接入过程。但是在SUL场景下,存在至少两个上行链路(UL)载波,所以现有配置方式,终端设备不知道使用哪个上行载波的资源。
因此,本发明实施例中,提出了一种确定非竞争随机接入资源的方法。使得终端设备存在至少两个上行链路(UL)载波时,能够确定非竞争随机接入资源。
下面结合图2对本发明实施例的竞争随机接入进行说明。
图2是本发明实施例的非竞争随机接入的方法的示意性流程图。
210,网络设备生成指示信息
220,网络设备向终端设备发送该指示信息
230,终端设备根据该指示信息进行随机接入
具体而言,网络设备生成指示信息,该指示信息指示终端设备用于非竞争随机接入的第一上行载波上的第一资源和/或第二上行载波上的第二资源,该第一上行载波的频点和该第二上行载波的频点不同;该网络设备向该终端设备发送指示信息。以便该终端设备根据接收到的该指示信息进行随机接入。
下面针对指示信息的具体内容进行示例性说明:
在一个实施例中,该指示信息可以包括该网络设备已经为终端设备选择的载波资源。换句话说,该网络设备直接向该终端设备指示该网络设备选择的载波资源。
例如,该指示信息可以包括:该第一上行载波的标识信息和用于指示该第一资源的信息。
又例如,该指示信息可以包括:该第二上行载波的标识信息和用于指示该第二资源的信息。
本发明实施例中,由于该载波资源由该网络设备选择。可选地,该网络设备生成指示信息之前,该网络设备接收该终端设备发送的信道质量测量报告;进而,该网络设备根据该信道质量测量报告,确定该终端设备用于非竞争随机接入的上行载波;并根据该终端设备用于非竞争随机接入的上行载波,生成该指示信息。
应理解,该信道质量测量报告包括但不限于:
该第一上行载波对应的小区的参考信号接收功率(Reference Signal Receiving Power,RSRP)和/或参考信号接收质量(Reference Signal Receiving Quality,RSRQ),以及该第二上行载波对应的小区的RSRP和/或RSRQ。
具体而言,该网络设备配置一套非竞争随机接入资源给该终端设备,并指示该套非竞争随机接入资源属于那个UL载波。具体地,网络设备可以根据该终端设备上报的测量结果报告来选择该终端设备发起非竞争随机接入资源的UL载波。例如,切换场景下,网络设备知道信号质量,此时,终端设备当前所在小区需要将该终端设备对目标小区的测量结果(例如,RSRP/RSRQ)发送给目标小区,用于目标小区选择UL载波。本发明实施例中,网络设备为终端设备配置专用随机接入资源时,可以参考该测量结果为终端设备配置专用随机接入资源。
在另一个实施例中,该指示信息可以包括每个上行载波上的资源。换句话说,该网络设备直接向该终端设备指示该终端设备可用的所有上行载波的资源,由该终端设备最终选择用于进行非竞争随机接入的资源。
例如,该指示信息可以包括:该第一上行载波的标识信息、该第二上行载波的标识信息、用于指示该第一资源的信息以及用于指示该第二资源的信息。
具体地,网络设备为该终端设备配置的每套非竞争随机接入资源都配有对应的UL载波号,指示该非竞争随机接入资源属于那个UL载波,进而,使得终端设备能够知道非竞争随机接入资源与UL载波的对应关系。例如,该终端设备可以根据RSRP测量结果选择非竞争随机接入资源,并发起随机接入过程。例如,当RSRP测量结果大于一定门限时,UE可以选择NR UL对应的非竞争随机接入资源。否则UE只能选择SUL对应的非竞争随机接入 资源。
进一步地,该指示信息还可以包括:
该第一资源对应的优先级信息和/或该第二资源对应的优先级信息。
由此,网络设备在配置两套非竞争随机接入资源时,每套非竞争随机接入资源配置一个优先级指示,指示该终端设备在测量信号条件允许的情况下(例如,RSRP大于一定门限),优先使用的一套非竞争随机接入资源。
可选地,该网络设备生成指示信息之前,该网络设备根据以下信息中的至少一项,确定该第一资源对应的优先级信息和/或该第二资源对应的优先级信息:
该第一上行载波的处理负荷、该第二上行载波的处理负荷、该第一上行载波的物理随机接入信道(Physical Random Access Channel,PRACH)资源的负荷情况和该第二上行载波的PRACH资源的负荷情况。
换句话说,该指示信息中该第一资源对应的优先级信息和/或该第二资源对应的优先级信息可以基于两个上行载波的处理负荷以及两个载波的PRACH资源的负荷情况来设置。
应理解,本发明实施例中,该终端设备用于非竞争随机接入的资源包括但不限于:前导码的标识信息和用于发送前导码的PRACH资源。
下面对本发明实施例中指示信息的传输方式进行示例说明:
在一个实施例中,该网络设备向该终端设备发送无线资源控制(Radio Resource Control,RRC)信令,该RRC信令包括该指示信息。也就是说,该指示信息携带在RRC信令中发送给终端设备。
在另一个实施例中,该网络设备向该终端设备发送物理下行链路控制信道(Physical Downlink Control Channel,PDCCH)命令(order),该PDCCH order包括该指示信息。也就是说,该指示信息携带在PDCCH order中发送给终端设备。
