  • Unlicensed spectrum is the spectrum that can be used for radio equipment communication divided by countries and regions. This spectrum is generally considered as shared spectrum, that is, communication equipment in different communication systems can meet the regulatory requirements set by the country or region on the spectrum. Using this spectrum does not require applying for a proprietary spectrum license from the government. In order to allow various communication systems that use unlicensed spectrum for wireless communication to coexist friendly on this spectrum, some countries or regions have stipulated regulatory requirements that must be met when using unlicensed spectrum. For example, in Europe, communication devices follow the principle of Listen Before Talk (LBT), that is, communication devices need to perform channel listening before sending signals on channels with unlicensed spectrum.
  • LBT Listen Before Talk
  • the communication device can send signals; if the channel monitoring result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot send signals. And in order to ensure fairness, in a transmission, the communication device uses the channel of the unlicensed spectrum for signal transmission time not to exceed the maximum channel occupation time (MCOT, Maximum Channel Occupation Time). For another example, in order to avoid subband interference to signals transmitted on the unlicensed spectrum channel, and to improve the detection accuracy of the communication device when detecting the unlicensed spectrum channel, the signal transmitted on the unlicensed spectrum channel needs Occupy at least a certain percentage of the channel bandwidth.
  • MCOT Maximum Channel Occupation Time

Description

一种随机接入方法及装置、通信设备 技术领域
本申请实施例涉及移动通信技术领域,具体涉及一种随机接入方及装置、通信设备。
背景技术
随着无线通信技术的发展,基于长期演进(LTE,Long Term Evolution)系统的授权辅助接入系统(LAA-LTE,Licensed-Assisted Access-Long Term Evolution)以载波聚合(CA,Carrier Aggregation)结构为基础,以授权频谱上的载波为主载波,以免授权频谱上的载波为辅载波向终端设备提供服务。在LAA-LTE系统中,主载波可以用于保证终端设备的初始接入以及一些关键业务的传输性能,而免授权频谱上的辅载波可用来对终端设备的非关键的大数据业务进行传输,从而达到平衡LTE小区负载的目的。在LAA-LTE系统中,随机接入信道(RACH,Random Access Channel)过程在主载波上进行,因此RACH功能没有针对免授权(Unlicensed)频谱进行优化。
随着移动网络的发展,免授权频谱被应用在新无线(NR,New Radio)系统中,NR Unlicensed(简称为NR-U)需要支持LAA的方式,同时还有独立布网(SA,Stand-Alone)的工作方式。对于SA的工作方式,RACH过程需要在Unlicensed频谱上完成,如何针对Unlicensed频谱对RACH功能进行优化是有待解决的问题。

具体实施方式
为便于理解本申请实施例的技术方案,以下对本申请实施例涉及到的相关技术进行说明。
1)免授权频谱
免授权频谱是国家和地区划分的可用于无线电设备通信的频谱,该频谱通常被认为是共享频谱,即不同通信系统中的通信设备只要满足国家或地区在该频谱上设置的法规要求,就可以使用该频谱,不需要向政府申请专有的频谱授权。为了让使用免授权频谱进行无线通信的各个通信系统在该频谱上能够友好共存,一些国家或地区规定了使用免授权频谱必须满足的法规要求。例如,在欧洲地区,通信设备遵循先听后说(LBT,Listen Before Talk)原则,即通信设备在免授权频谱的信道上进行信号发送前,需要先进行信道侦听,只有当信道侦听结果为信道空闲时,该通信设备才能进行信号发送;如果通信设备在免授权频谱的信道上的信道侦听结果为信道忙,该通信设备不能进行信号发送。且为了保证公平性,在一次传输中,通信设备使用免授权频谱的信道进行信号传输的时长不能超过最大信道占用时间(MCOT,Maximum Channel Occupation Time)。又例如,为了避免对在免授权频谱信道上传输的信号造成子带干扰,也为了提高通信设备在对免授权频谱的信道进行检测时的检测准确性,在免授权频谱信道上传输的信号需要至少占用该信道带宽的一定比例,例如,5GHz频段为信号占用信道带宽的80%,60GHz频段为信号占用信道带宽的70%。又例如,为了避免在免授权频谱的信道上传输的信号的功率太大,影响该信道上的其他重要信号,例如雷达信号等的传输,法规规定了通信设备使用免授权频谱的信道进行信号传输时的最大功率谱密度。
2)网络架构
本申请实施例可以应用于各种通信系统,例如:全球移动通讯(GSM,Global System of Mobile communication)系统、码分多址(CDMA,Code Division Multiple Access)系统、宽带码分多址(WCDMA,Wideband Code Division Multiple Access)系统、通用分组无线业务(GPRS,General Packet Radio Service)、通用移动通信系统(UMTS,Universal Mobile Telecommunication System)、LTE系统及LTE系统的演进系统,例如先进的长期演进(LTE-A,Advanced long term evolution)系统、NR系统及NR系统 的演进系统,例如免授权频谱上的NR(NR-U,NR-based access to Unlicensed spectrum)系统、或下一代通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如,设备到设备(D2D,Device to Device)通信,机器到机器(M2M,Machine to Machine)通信,机器类型通信(MTC,Machine Type Communication),以及车辆间(V2V,Vehicle to Vehicle)通信。
本申请实施例中的通信系统可以应用于CA场景,也可以应用于SA布网场景。
示例性的,本申请实施例应用的通信系统100如图1所示。该通信系统100可以包括网络设备110,网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域内的终端设备进行通信。可选地,该网络设备110可以是GSM系统或CDMA系统中的基站(Base Transceiver Station,BTS),也可以是WCDMA系统中的基站(NodeB,NB),还可以是LTE系统中的演进型基站(Evolutional Node B,eNB或eNodeB),或者是云无线接入网络(Cloud Radio Access Network,CRAN)中的无线控制器,或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)中的网络设备等。

可选地,终端设备120之间可以进行终端直连(Device to Device,D2D)通信。
可选地,5G系统或5G网络还可以称为新无线(New Radio,NR)系统或NR网络。
图1示例性地示出了一个网络设备和两个终端设备,可选地,该通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备,本申请实施例对此不做限定。
可选地,该通信系统100还可以包括网络控制器、移动管理实体等其他网络实体,本申请实施例对此不作限定。
应理解,本申请实施例中网络/系统中具有通信功能的设备可称为通信设备。以图1示出的通信系统100为例,通信设备可包括具有通信功能的网络设备110和终端设备120,网络设备110和终端设备120可以为上文所述的具体设备,此处不再赘述;通信设备还可包括通信系统100中的其他设备,例如网络控制器、移动管理实体等其他网络实体,本申请实施例中对此不做限定。
应理解,本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
3)RACH过程
3.1)RACH过程可以由以下事件触发:
RRC空闲下的初始接入;
RRC连接重建过程;
切换过程;
在上行同步状态非同步的情况下,在RRC连接态下有下行或上行数据到达;
从RRC非激活态转变为其他状态,例如RRC激活态;

逻辑信道没有配置相应调度请求配置且该逻辑信道触发了调度请求。
3.2)RACH过程的形式

(2)非竞争的RACH(CF-RACH,Contention-Free RACH)过程,参照图2(b)。
对于NR Unlicensed,需要支持LAA的方式,同时还有SA的工作方式;对于SA的工作方式,RACH过程需要在Unlicensed频谱上完成,因此,RACH功能需要针对Unlicensed频谱的要求做进一步优化,同时也需要满足Unlicensed频谱的接入要求,比如LBT。
对于NR工作在Unlicensed频谱,支持如下场景:NR授权频谱(主载波)和NR非授权频谱(辅载波)的载波聚合、LTE授权频谱(主载波)和NR非授权频谱(辅载波)的双连接架构、NR非授权频谱的SA架构、一个NR小区包括下行非授权频谱和上行授权频谱、NR授权频谱(主载波)和NR非授权频谱(辅载波)的双连接架构。
对于SA架构的NR非授权频谱(NR-U),UE需要在非授权频谱上进行RACH过程,RACH在非授权频谱上如何工作,比如如何确定接入信道需要定义。
4)信道接入优先等级(Channel Access Priority Class)
LAA定义了两种接入类型,分别为Type1和Type2;其中,
对于Type1这种接入类型,终端可以根据业务类型选择不同的信道接入优先等级。对Type1的接入方式,进一步有如下表1所示的四种信道接入优 先等级:
信道接入优先等级(p) QCI(QoS Class Identifier)
1 1,3,5,65,66,69,70
2 2,7
3 4,6,8,9
4 -
表1
对于Type2这种接入类型,终端在传输物理上行共享信道(PUSCH,Physical Uplink Shared Channel)之前需要固定侦听25us的时间。
