Description

一种非授权载波占用时长的管理方法和装置 技术领域
本申请涉及但不限于通信领域,尤其涉及一种非授权载波占用时长的管理方法和装置。
背景技术
截止目前,众所周知LTE(Long Term Evolution,长期演进)是部署在授权载波中运营的。但是随着LTE的演进,在2013年下半年一些公司(例如美国高通公司)提出了:建议研究LTE部署在非授权载波中的课题。但是截止当前仍然未被LTE接受和立项。
高通公司给出的立项理由主要是:随着数据业务的快速增长,在不久的将来,授权频谱将不能再承受如此巨大的数据量。所以建议考虑在非授权频谱中部署LTE,通过非授权频谱来分担授权载波中的数据流量。
另外,非授权频谱也存在很多优势。例如,非授权频谱具有下面的特征:
1、免费/低费用(不需要购买非频谱,频谱资源为零成本);
2、准入要求低,成本低(个人、企业都可以参与部署,设备商的设备可以任意);
3、共享资源(多个不同系统都运营其中时或者同一系统的不同运营商运营其中时,可以考虑一些共享资源的方式,提高频谱效率);
4、无线接入技术多(跨不同的通信标准,协作难,网络拓扑多样);
5、无线接入站点多(用户数量大,协作难度大,集中式管理开销大);
6、应用多(从资料看,多业务被提及可以在其中运营,例如机器到机器(Machine to machine,M2M)、车对车(Vehicle to vehicle,V2V))。
上述的基本特征,决定了非授权频谱可能是无线通信系统一个重要的演进方向,但是同时也存在诸多问题。例如,非授权频谱中将存在各种各样的无线系统,彼此之间难于协调,干扰严重。
如果LTE系统运营在非授权载波,那么LTE基站抢占到非授权载波资源时,占用时长如何与LTE的子帧调度完美结合,避免资源浪费,同时也使得调度的复杂度大大降低以及标准化设计工作量减少,以及在适合LTE的竞争回退机制的约束下,占用时长如何考虑更加合理,都是需要解决的问题。

附图概述

图2为本发明实施例提供的非授权载波占用时长的管理装置的结构图。
本发明的实施方式
下面将结合附图及实施例对本申请作进一步的详细描述。需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互任意组合。
图1为本发明实施例提供的非授权载波占用时长的管理方法的流程图。图1所示方法包括以下步骤:
步骤101、站点执行空闲信道检测(CCA)和/或扩展的空闲信道检测(eCCA)(下面以CCA/eCCA代替之);
步骤102、所述站点根据执行CCA/eCCA成功的子帧或调度单位中的正交频分复用(OFDM)符号位置或子帧位置,确定占用时长的结束位置;或者,所述站点确定占用时长的结束位置为占用最后一个子帧中前3、6、9、10、11、12或14个符号被占用。
LTE部署在非授权载波中,在LTE的研究和演进过程中称为LAA(Licensed-Assisted Access,授权频谱辅助接入)系统。本申请考虑结合LTE基于子帧(1ms时长)为单位的调度规则,定义不同的、合适的非授权载波占用时长的结束点,使得占用时长内最后一个子帧中的数据映射可以重用相关LTE的部分规则,从而减少设计的复杂度和不必要的标准化工作量。
站点占用非授权载波时,根据CCA/eCCA成功的时刻点来决定占用时长。一般地,在非授权载波单次占用最大时长是受限制的,例如在欧洲为13ms,在日本是4ms,不同国家或地区自行规定。由于CCA/eCCA执行成功的时刻点可以是子帧内任意时刻点,如果站点占用整数毫秒(ms)进行占用,那么几乎每次(概率很大)占用时长内最后一个子帧都会是非完整子帧。本申请提出根据CCA/eCCA执行成功的符号位置,确定占用时长内最后一个子帧中包含的OFDM符号数。
可选地,LAA站点执行CCA/eCCA成功时,站点判断所处的OFDM符号位置,此时可以参考与该非授权载波配对使用的主载波(是一个授权载波) 的定时(包括子帧定时、OFDM定时)。对于站点的时长进行确定,此时可以根据负载(下行和/或上行负载)情况,然后确定占用时长(可以是以整数ms为单位进行描述,或者以子帧数进行描述,或者以调度单位(本文所述调度单位包括1ms,即由14个OFDM符号或12个OFDM符号组成;还包括0.5ms,即由7个或6个OFDM符号组成)进行描述),并根据表1中的规则确定最后一个子帧中占用的OFDM符号数量。
表1
Figure PCTCN2016082347-appb-000001
需要注意的是:对于CCA/eCCA成功时刻位于第4个至第6个OFDM符号时,最后一个子帧中占用的OFDM符号数还可以对应为0或2。
可选地,LAA站点执行CCA/eCCA成功时,站点判断所处的OFDM符号位置,此时可以参考与该非授权载波配对使用的主载波(是一个授权载波) 的定时(包括子帧定时、OFDM定时)。对于站点的时长进行确定,此时可以根据负载(下行和/或上行负载)情况,然后确定占用时长(可以是以整数ms为单位进行描述,或者以子帧数进行描述,或者以调度单位进行描述),并根据表2中的规则确定最后一个子帧中占用的OFDM符号数量。
在最终的占用总时长不超过管制或协议规定的单次占用最大时长的情况下,表2给出就近原则来产生最后一个子帧的符号数据。
表2
Figure PCTCN2016082347-appb-000002
需要注意的是:表1和表2都是针对标准循环前缀(CP,Cyclic Prefix) 的情况,对于扩展CP也可以采用类似的处理方式。当按照表2中确定的占用时长超过管制最大时长时,站点不再按照表2执行,而是按照表1执行,其他情况按照表2执行。
对于占用的最后一个子帧中有2个或3个OFDM符号(最后一个子帧的前2个或前3个符号被占用)的情况,对于占用站点进一步使用该符号的方法描述如下(以后一个子帧为部分子帧,前一个子帧为完整子帧为例,反之也可以使用):
方式一
站点将子帧n和子帧n+1中的部分OFDM符号合并作为超子帧使用时,站点超子帧选择计算数据映射的NPRB取值的折算因子的计算方法如下:考虑到子帧n+1中会存在控制域,但是不再承载下行控制信息,所以,为控制域预留1个OFDM符号,完整子帧中一般使用2个符号作为控制域,因此,计算公式为:当子帧n+1中有2个符号被用于数据传输时,则超子帧的折算因子为:(12+2)/12(其中,12为设定完整子帧的情况下对应的因子,2为新增加OFDM符号,类似的原理被使用在下面的情况);当子帧n+1中有3个符号被用于数据传输时,则超子帧的折算因子为:(12+3)/12。因此,超子帧的折算因子的范围为:1+1/6~1+1/4;可选为1.2。
或者,当站点独立使用子帧n+1中的部分OFDM符号进行数据传输时,计算原理同上,站点选择计算数据映射的NPRB取值的折算因子的范围为1/6~1/4,可选为0.2。由于实际无线链路中的信道质量测量并不能毫无误差的反应,所以,仿真验证后,1/6和1/4的情况下,性能比较接近,为了简单,减少信令开销,综合后给出统一的折算因子为0.2,或者对应超子帧的折算因子为1.2。
方式二
站点将子帧n和子帧n+1中的部分OFDM符号合并作为超子帧使用时,站点超子帧选择计算数据映射的NPRB取值的折算因子根据以下方式确定:
子帧n+1中有2个或3个且不用于控制域的OFDM符号被合并作为超子帧使用时,当子帧n中PDCCH占用1个符号,数据映射的NPRB取值的折算 因子为:1.23(计算方法为:(12+3)/(13));子帧n中PDCCH占用2个符号时,数据映射的NPRB取值的折算因子为:1.25(计算方法为:(12+3)/(12));子帧n中PDCCH占用3个符号时,数据映射的NPRB取值的折算因子为:1.27(计算方法为:(12+3)/(11))。
由于实际无线链路中的信道质量测量并不能毫无误差的反应,所以,仿真验证后,1.23、1.25和1.27的对应的情况下,性能比较接近,为了简单,减少信令开销,综合后,不管子帧n中PDCCH占用的符号数,数据映射的NPRB取值的折算因子均为:1.25。
方式三
站点将子帧n和子帧n+1中的部分OFDM符号合并作为超子帧使用时,站点超子帧选择计算数据映射的NPRB取值的折算因子根据以下方式确定:
子帧n+1中有2个或3个OFDM符号且包括控制域被合并作为超子帧使用时,当子帧n中PDCCH占用1个OFDM符号时,数据映射的NPRB取值的折算因子为:1.15(计算方式为(13+2)/13);当子帧n中PDCCH占用2个符号时,数据映射的NPRB取值的折算因子为:1.16(计算方式为(12+2)/12);子帧n中PDCCH占用3个符号时,数据映射的NPRB取值的折算因子为:1.18(计算方式为(11+2)/11)。
由于实际无线链路中的信道质量测量并不能毫无误差的反应,所以,仿真验证后,1.15、1.16和1.18的对应的情况下,性能比较接近,为了简单,减少信令开销,综合后,不管子帧n中PDCCH占用的符号数,数据映射的NPRB取值的折算因子均为:1.16。
占用时长的指示或者占用结束位置的确定通过如下方式实现:
LAA站点(包括基站和UE)能够通过检测(盲检约定的序列来间接确定)或接收信令确定LAA站点占用非授权载波的起始位置(包括按照OFDM符号进行描述,或描述为时刻点,或描述为随机回退值,或者是LAA站点开始发送数据的时刻点等),然后LAA站点能够通知占用的完整子帧数量(其中包括或不包括最后一个部分子帧,下面按照不包括最后一个部分子帧为例, 以减少信令开销;如果包括,处理过程是类似的),然后LAA站点或接收端根据表1和/或表2的方式再结合通知占用的完整子帧数量,就可以推算出LAA站点占用的结束时刻点(最后一个子帧的占用的符号)。
例如,LAA站点计划占用5ms(一个子帧为1ms,包括14个OFDM符号),站点在子帧n中执行CCA/eCCA成功,获得使用权,并从成功时刻点(UE可以检测出来或者站点明确通知UE)算作占用时长起点,假设站点在子帧n的第7个OFDM符号中执行CCA/eCCA成功,那么接收端和该站点根据表1和/或表2可以确定占用时长内最后一个子帧中有几个OFDM符号被占用。此时LAA站点通知占用的完整子帧数量即可,例如完整子帧为4个,分别为子帧n+1、n+2、n+3、n+4;之后还有一个子帧n+5,但是子帧n+5只占用了部分OFDM符号。
子帧的定时根据该非授权载波配对的主载波来确定。
通知完整子帧数量的信令能够在非授权载波或授权载波中发送,且占用期间的每一个子帧均可以发送(此时占用时长采用递减描述方式描述,例如描述该子帧之后(包括或不包括当前子帧)还剩余几个完整子帧)。
接收端,接收通知占用起始点的信令,或者通过盲检获得,接收完整子帧占用的信令,根据表1和/或表2获知最后一个非完整子帧中占用的符号数,然后根据起始点、完整子帧数、最后一个子帧占用的符号,最后确定LAA站点占用的时长。
占用完整子帧的数量通过DCI(Downlink Control Information,下行控制信息)来发送,且可以放置在PDCCH或ePDCCH(enhanced Physical Downlink Control Channel,增强物理下行控制信道)公共检索区域或UE专用检索区域。且使用约定公共RNTI(Radio Network Temporary Identifier,无线网络临时标识)加扰或UE的RNTI加扰。如果站点占用的时长为管制或协议规定的最大时长时,完整子帧的数量可以不发送,接收端和发送端认为按照最大时长占用。
本实施例还提供一种接收端接收结束方式的确定方法,当站点使用非授权载波传输数据时,接收端通过检测信道从忙变为闲的时刻,将该时刻作为接收数据的结束时刻。
例如,在站点占用非授权载波的时长内的最后一个子帧时,经常出现站点仅仅占用了该子帧的部分符号。当站点使用该子帧为接收端发送数据,但是接收端并未获知站点占用非授权的时长在哪里结束,当接收端确定自己被调度时(例如接收到控制信令),但是并不知道数据信道结束的具体符号位置,接收端接收该子帧的信号,并将信道(该非授权载波)从忙变为闲的时刻作为一个该子帧的结束时刻点,接收端的数据被传输在该子帧内且在该时刻点之前。
其中,信道从忙变为闲是指:执行CCA/eCCA时,检测到的信道信号能量从高变为低于门限。
接收端使用上述方式可以确定自己的数据在该子帧的符号位置,从而解码。
