Description

非授权载波的调度方法、设备和系统、计算机存储介质 技术领域
本发明涉及无线通信技术，尤其涉及一种非授权载波的调度方法、设备和系统、计算机存储介质。
背景技术
截止目前，众所周知长期演进(LTE)是部署在授权载波中运营的。但是随着LTE的演进，LTE部署在非授权载波中的课题也需要进行研究。
非授权载波具有下面的特征：
1、免费/低费用：不需要购买非授权频谱，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部署。
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：可以使用不同的通信标准，但协作难度大，网络拓扑多样。
5、无线接入站点多：用户数量大，但协作难度大，集中式管理开销大。
6、应用多：多种业务可以在其中运营，例如：机器到机器(M2M，Machine to machine)业务、汽车到汽车(V2V，Vehicle to vehicle)业务。
上述特征决定了非授权载波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：非授权载波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。
目前，非授权载波在LTE中的使用主要基于载波聚合(CA，Carrier Aggregation)和双联接(DC，Dual Connectivity)的方式，当以载波聚合方 式进行运营时，LTE授权载波作为主载波，而非授权载波作为辅载波，其中作为辅载波的非授权载波有两种形式：SDL和TDD，其中，在SDL方式中，非收授权载波作为只传输数据的下行载波，在TDD方式中，非授权载波以TDD方式(既有上行传输也有下行传输)进行运营。
当采用TDD方式的非授权载波形式，假设在子帧n，通过LTE授权载波跨载波调度在非授权载波进行上行传输，即非授权载波的上行传输时刻为n+k；当使用传送前侦听(LBT，Listening Before Transmission)机制进行U载波(非授权载波，Unlicensed carrier)资源占用时，若eNB在接近n+k的时刻未成功抢占到U资源，这里，可能的原因包括：主系统的回归导致基站退出当前竞争到的资源，以及其他强干扰系统导致基站传输可靠性降低而退出竞争到的资源等，则产生非授权载波调度定时与载波占用时刻不匹配的问题，若UE仍按照原先的调度定时在非授权载波进行传输时，考虑到其他系统的设备在相同的非授权载波传输，此时UE在n+k时刻的物理上行共享信道(PUSCH)的数据传输性能会受到影响，且同时会降低其他系统设备的数据传输性能。
此外，按照现有的混合自动重传请求(HARQ)协议规定，数据的首传和重传需在相同的载波上，假设使用LBT成功竞争到了n+k时刻的非授权载波，UE在n+k时刻利用非授权载波发送数据，但是，由于信道的影响，数据发生错误，则UE需要在预定义的HARQ定时处进行数据重传，例如：在子帧n+k+m处进行数据重传，这样，若在子帧n+k+m处使用LBT机制未成功竞争到非授权载波，则也会发生上述提到的非授权载波调度定时与载波占用时刻不匹配的问题。
考虑到LTE和其他无线系统在非授权载波共同运营时，公平性是保证两者和谐共存的重要保证，而公平性最主要体现在各无线接入技术不应影响其他无线接入技术的频谱需求和服务性能。
综上分析，为了保证LTE系统和其他无线系统在非授权频谱中的和谐共存，需要解决上述技术问题。

具体实施方式
本发明实施例中，基站在确定需要发送指示调度终止的信令和/或指示调度更新的信令时，在授权载波中发送指示调度终止的信令和/或指示调度更新的信令，UE在授权载波中接收指示调度终止的信令和/或指示调度更新的信令，根据指示调度终止的信令，终止在起始调度资源位置传输数据，和/或，根据指示调度更新的信令，在新的调度资源位置传输数据。
下面通过附图及具体实施例对本发明做进一步的详细说明。
本发明实施例实现一种非授权载波的调度方法，如图1所示，该方法包括以下几个步骤：
步骤101：基站确定需要发送指示调度终止的信令和/或指示调度更新的信令；
具体的，基站通过确定非授权载波调度定时与载波占用时刻不匹配确定需要发送指示调度终止的信令和/或指示调度更新的信令；其中，
所述确定非授权载波调度定时与载波占用时刻不匹配，包括：基站在成功占用非授权载波的前提下发送所述非授权载波的资源授权，但基站在非授权载波调度定时时刻(或调度定时时刻之前)发现所述非授权载波已不再被自身占用(包括主系统的回归导致基站释放当前竞争到的资源，以及其他强干扰系统导致基站传输可靠性降低而释放竞争到的资源等)，或者，基站发送计划占用的非授权载波的资源授权信息，但基站在非授权载波调度定时时刻(或调度定时时刻之前)发现自身不能占用到所述非授权载波。
步骤102：基站在授权载波中发送指示调度终止的信令和/或指示调度更新的信令；
具体的，基站在授权载波中将调度终止指示信息和/或相对于起始调度资源位置的偏置(offset)值发送给UE，所述offset值为基站预先设置的；例如，在n时刻，基站发送非授权载波的资源授权，非授权载波的调度定时处(也可称，原先的调度资源位置)为子帧n+k，n、k均为正整数，若基站在接近n+k的子帧处(接近n+k的子帧为n+k-j的子帧，j取大于等于1的整数)未成功竞争到资源(包括主系统的回归导致基站退出当前竞争到的资源，以及其他强干扰系统导致基站传输可靠性降低而退出竞争到的资源，以下都以未成功竞争到资源进行描述)，即非授权载波调度定时与载波占用时刻不匹配，则基站在授权载波中发送调度终止指示信息和/或相对于 起始调度资源位置的偏置(offset)值给UE，例如：新的调度资源位置相对于起始调度资源位置的offset为m，则UE将在n+k+m的子帧处进行数据传输。
所述基站可以通过物理层信令发送调度终止指示信息和/或相对于起始调度资源位置的offset值给UE，比如：所述基站通过物理层下行控制信息(DCI，Downlink Control Information)发送调度终止指示信息和/或相对于起始调度资源位置的offset值给UE。
这样，基站通过物理层DCI发送调度终止指示信息可以是：基站使用DCI中的载波指示比特域(CIF)的保留比特状态指示调度终止，或者，以位图(bitmap)的方式指示调度终止，或者，在DCI中设置专用的比特指示调度终止。
对于基站在时域连续发送UE的多个UL grant的情形，在物理层DCI中以bitmap的方式定义调度进程是否有效的指示，基站通过物理层DCI以bitmap的方式在授权载波中指示无效的调度进程；或者，基站可预先设置不同进程与物理层DCI的不同发送时刻的图样关系，基站根据所述图样关系在进程对应的时刻发送物理层DCI指示所述进程无效。
所述基站在指定时刻在授权载波中发送调度终止的指示和/或相对于起始调度资源位置的offset值，优选的，约定基站在抢占非授权载波资源未成功之后第一个子帧中、且在授权载波中发送调度终止的指示和/或相对于起始调度资源位置的offset值；或者，基站在预定义的与UE进程对应的子帧中、且在授权载波中发送调度终止的指示和/或相对于起始调度资源位置的offset值。
所述基站通过物理层DCI发送相对于起始调度资源位置的offset值给UE，可以是：基站预先建立offset值与比特状态的映射图样，通过DCI中的比特状态来指示offset值或使用bitmap的方式来指示offset值，优选的， 可利用CIF比特域的保留比特状态来指示offset值。
所述offset的取值分为同步HARQ和异步HARQ两种不同情形，对于同步HARQ情形，offset取值至少为以下之一：满足为4的倍数、满足n+4+10*N(N为大于等于0的整数)、满足n+7+10*N(N为大于等于0的整数)、满足n+6+10*N(N为大于等于0的整数)；对于异步HARQ情形，offset取值为M(M为大于等于1的整数)，在异步HARQ情形下发送offset值时，还需要额外的比特来指示通过offset值获得的新调度定时处的进程号，所述额外的比特可通过物理层信令以bitmap的方式携带。
或者，基站在候选非授权载波集合中选择新的非授权载波作为UE的调度载波，在授权载波中将调度终止指示信息和/或从候选非授权载波集合中选择的新的非授权载波的信息发送给UE；例如，在n时刻，基站发送非授权载波的资源授权，非授权载波的调度定时处(也可称，原先的调度资源位置)为子帧n+k、且在非授权载波c1上，若基站在接近n+k的子帧处(接近n+k的子帧为n+k-j的子帧，j取大于等于1的整数)未成功竞争到c1资源，即非授权载波调度定时与载波占用时刻不匹配，则基站从非授权载波集合中选择一个非授权载波c2作为新的调度载波，在授权载波中将调度终止指示信息和/或非授权载波c2的信息发送给UE，UE在调度资源位置n+k处，在非授权载波c2中传输数据。
具体的，基站将调度终止指示信息发送给UE，可以是：基站通过物理层DCI向UE指示原先载波调度终止，优选的，使用DCI中的CIF比特域的保留比特状态来指示原先载波调度终止，或者在DCI中设置专用的比特来指示原先载波调度终止，或者使用约定的RNTI加扰物理层信令来指示原先载波调度终止。
所述候选非授权载波集合为UE特定(UE-specific)形式或小区特定(cell-specific)形式，所述候选非授权载波集合中的候选非授权载波基于基 站或UE的测量结果或其他原则选定；例如，基站基于自身对于非授权载波的测量结果，选择合适的非授权载波作为候选非授权载波，此时，所有UE拥有相同的候选非授权载波集合，按照这种方式配置的候选非授权载波集合为cell-specific形式的，反之，若基于UE反馈的非授权载波的测量结果，为UE配置合适的候选非授权载波集合，所述候选非授权载波集合为UE-specific形式的。
这里，基站或UE对非授权载波的测量为：在给定观测时间内，在非授权载波的给定带宽上基站或UE所观测到的能量的线性平均值，其中，所观测到的能量来自与非授权载波小区同频的其他小区，和/或与基站分属不同系统的站点，和/或非授权载波相邻的频带泄露到当前频带的能量，和/或热噪声产生的能量；此外，所述给定的观测时间优选为单个或多个OFDM符号，所述非授权载波的给定带宽优选为全带宽。
可选的，基站通过物理层DCI将新的非授权载波的信息通知UE，其中，当基站为调度在起始载波上的所有UE配置新的非授权载波时，可通过bitmap的方式描述新的非授权载波，所使用的DCI格式原则上选择易于盲检索的格式，例如：DCI格式对应的比特数唯一，可以是：预定义DCI格式的前M比特(M大于等于1)携带新的非授权载波信息，预先定义候选非授权载波集合中的候选非授权载波与预定义DCI格式的前M比特的映射关系，例如，假设M取5，以00001表示C1载波，00010表示C2载波，00100表示C3载波，基于候选非授权载波数量的变化可以调整预定义DCI格式中的M值。
另外，所述基站还可以利用约定的RNTI加扰DCI来指示原先的非授权载波调度终止，并利用DCI中的CIF比特域的保留比特状态指示新的非授权载波，或者，利用DCI中的CIF比特域的保留比特状态指示原先的非授权载波调度终止，选择DCI中的前M比特(M大于等于1)以bitmap 的方式描述新的非授权载波；其中，所述DCI信息使用约定的RNTI加扰，并在PDCCH或ePDCCH公共检索空间发送，或者在约定资源中发送，其中，利用bitmap的方式描述新的非授权载波时，可同时描述原先的非授权载波，用于指示原先的非授权载波调度终止。
对于候选非授权载波集合为UE-specific的方式，可使用UE分配的C-RNTI加扰DCI，此时，DCI中的CIF比特域为保留比特状态，预定义CIF比特状态101表示原先的非授权载波调度终止，采用bitmap的方式描述新的非授权载波，所述DCI信息在PDCCH或ePDCCH专用检索空间发送，或者在约定资源中发送。

本发明实施例实现第一种非授权载波的调度方法，如图3所示，该方法包括以下几个步骤：
步骤301：基站在确定需要发送指示调度终止的信令和/或指示调度更新的信令时，在授权载波中发送指示调度终止的信令和/或指示调度更新的信令；
步骤302：UE在授权载波中接收指示调度终止的信令和/或指示调度更新的信令，根据指示调度终止的信令，终止在起始调度资源位置传输数据，和/或，根据指示调度更新的信令，在新的调度资源位置传输数据。
其中，步骤301采用图1所示实施例的步骤，步骤302采用图2所示实施例的步骤，这里不再重复描述。
本发明实施例提供一种基站，如图4所示，该基站包括：确定模块41、信令发送模块42；其中，
确定模块41确定需要发送指示调度终止的信令和/或指示调度更新的 信令，并通知信令发送模块42；信令发送模块42在授权载波中发送指示调度终止的信令和/或指示调度更新的信令。
具体的，确定模块41通过确定非授权载波调度定时与载波占用时刻不匹配确定需要发送指示调度终止的信令和/或指示调度更新的信令，所述确定非授权载波调度定时与载波占用时刻不匹配，包括：基站在成功占用非授权载波的前提下发送所述非授权载波的资源授权，但基站在非授权载波调度定时时刻(或调度定时时刻之前)发现所述非授权载波已不再被自身占用(包括主系统的回归导致基站释放当前竞争到的资源，以及其他强干扰系统导致基站传输可靠性降低而释放竞争到的资源等)，或者，基站发送计划占用的非授权载波的资源授权信息，但基站在非授权载波调度定时时刻(或调度定时时刻之前)发现自身不能占用到该非授权载波。
具体的，信令发送模块42在授权载波中将调度终止指示信息和/或相对于起始调度资源位置的偏置(offset)值发送给UE，所述offset值为基站预先设置的；例如，在n时刻，基站发送非授权载波的资源授权，非授权载波的调度定时处(也可称，原先的调度资源位置)为子帧n+k，n、k均为正整数，若基站在接近n+k的子帧处(接近n+k的子帧为n+k-j的子帧，j取大于等于1的整数)未成功竞争到资源(包括主系统的回归导致基站退出当前竞争到的资源，以及其他强干扰系统导致基站传输可靠性降低而退出竞争到的资源，以下都以未成功竞争到资源进行描述)，即非授权载波调度定时与载波占用时刻不匹配，则信令发送模块42在授权载波中发送调度终止指示信息和/或相对于起始调度资源位置的偏置(offset)值给UE，例如：新的调度资源位置相对于起始调度资源位置的offset为m，则UE将在n+k+m的子帧处进行数据传输。
所述信令发送模块42可以通过物理层信令发送调度终止指示信息和/或相对于起始调度资源位置的offset值给UE，比如：所述信令发送模块42 通过物理层下行控制信息(DCI，Downlink Control Information)发送调度终止指示信息和相对于起始调度资源位置的offset值给UE。
这样，信令发送模块42通过物理层DCI发送调度终止指示信息可以是：信令发送模块42使用DCI中的载波指示比特域(CIF)的保留比特状态指示调度终止，或者，以位图(bitmap)的方式指示调度终止，或者，在DCI中设置专用的比特指示调度终止。
对于基站在时域连续发送UE的多个UL grant的情形，在物理层DCI中以bitmap的方式定义调度进程是否有效的指示，信令发送模块42通过物理层DCI以bitmap的方式在授权载波中指示无效的调度进程；或者，基站预先设置不同进程与物理层DCI的不同发送时刻的所述图样关系，信令发送模块42根据所述图样关系在进程对应的时刻发送物理层DCI指示所述进程无效。
所述信令发送模块42在指定时刻在授权载波中发送调度终止的指示和/或相对于起始调度资源位置的offset值，优选的，约定在抢占非授权载波资源未成功之后第一个子帧中、且在授权载波中发送调度终止的指示和/或相对于起始调度资源位置的offset值；或者，在预定义的与UE进程对应的子帧中、且在授权载波中发送调度终止的指示和/或相对于起始调度资源位置的offset值。
所述信令发送模块42通过物理层DCI发送相对于起始调度资源位置的offset值给UE，可以是：信令发送模块42预先建立offset值与比特状态的映射图样，通过DCI中的比特状态来指示offset值或使用bitmap的方式来指示offset值，优选的，可利用CIF比特域的保留比特状态来指示offset值。
所述offset的取值分为同步HARQ和异步HARQ两种不同情形，对于同步HARQ情形，offset取值至少为以下之一：满足为4的倍数、满足n+4+10*N(N为大于等于0的整数)、满足n+7+10*N(N为大于等于0的 整数)、满足n+6+10*N(N为大于等于0的整数)；对于异步HARQ情形，offset取值为M(M为大于等于1的整数)，在异步HARQ情形下发送offset值时，还需要额外的比特来指示通过offset值获得的新调度定时处的进程号，所述额外的比特可通过物理层信令以bitmap的方式携带。
或者，信令发送模块42在候选非授权载波集合中选择新的非授权载波作为UE的调度载波，在授权载波中将调度终止指示信息和/或从候选非授权载波集合中选择的新的非授权载波的信息发送给UE；例如，在n时刻，基站发送非授权载波的资源授权，非授权载波的调度定时处(也可称，原先的调度资源位置)为子帧n+k、且在非授权载波c1上，若基站在接近n+k的子帧处(接近n+k的子帧为n+k-j的子帧，j取大于等于1的整数)未成功竞争到c1资源，即非授权载波调度定时与载波占用时刻不匹配，则信令发送模块42从非授权载波集合中选择一个非授权载波c2作为新的调度载波，在授权载波中将调度终止指示信息和/或非授权载波c2的信息发送给UE，UE在调度资源位置n+k处，在非授权载波c2中传输数据。
具体的，信令发送模块42将调度终止指示信息发送给UE，可以是：信令发送模块42通过物理层DCI向UE指示原先载波调度终止，优选的，使用DCI中的CIF比特域的保留比特状态来指示原先载波调度终止，或者在DCI中设置专用的比特来指示原先载波调度终止，或者使用约定的RNTI加扰物理层信令来指示原先载波调度终止。
所述候选非授权载波集合为UE-specific形式或cell-specific形式，所述候选非授权载波集合中的候选非授权载波基于基站或UE的测量结果或其他原则选定；例如，基站基于自身对于非授权载波的测量结果，选择合适的非授权载波作为候选非授权载波，此时，所有UE拥有相同的候选非授权载波集合，按照这种方式配置的候选非授权载波集合为cell-specific形式的，反之，若基于UE反馈的非授权载波的测量结果，为UE配置合适的候选非 授权载波集合，所述候选非授权载波集合为UE-specific形式的。
这里，基站或UE对非授权载波的测量为：在给定观测时间内，在非授权载波的给定带宽上基站或UE所观测到的能量的线性平均值，其中，所观测到的能量来自与非授权载波小区同频的其他小区，和/或与基站分属不同系统的站点，和/或非授权载波相邻的频带泄露到当前频带的能量，和/或热噪声产生的能量；此外，所述给定的观测时间优选为单个或多个OFDM符号，所述非授权载波的给定带宽优选为全带宽。
可选的，信令发送模块42通过物理层DCI将新的非授权载波的信息通知UE，其中，当信令发送模块42为调度在起始载波上的所有UE配置新的非授权载波时，可通过bitmap的方式描述新的非授权载波，所使用的DCI格式原则上选择易于盲检索的格式，例如：DCI格式对应的比特数唯一，可以是：预定义DCI格式的前M比特(M大于等于1)携带新的非授权载波信息，预先定义候选非授权载波集合中的候选非授权载波与预定义DCI格式的前M比特的映射关系，例如，假设M取5，以00001表示C1载波，00010表示C2载波，00100表示C3载波，基于候选非授权载波数量的变化可以调整预定义DCI格式中的M值。
另外，所述信令发送模块42还可以利用约定的RNTI加扰DCI来指示原先的非授权载波调度终止，并利用DCI中的CIF比特域的保留比特状态指示新的非授权载波，或者，利用DCI中的CIF比特域的保留比特状态指示原先的非授权载波调度终止，选择DCI中的前M比特(M大于等于1)以bitmap的方式描述新的非授权载波；其中，所述DCI信息使用约定的RNTI加扰，并在PDCCH或ePDCCH公共检索空间发送，或者在约定资源中发送，其中，利用bitmap的方式描述新的非授权载波时，可同时描述原先的非授权载波，用于指示原先的非授权载波调度终止。
对于候选非授权载波集合为UE-specific的方式，信令发送模块42可使 用UE分配的C-RNTI加扰DCI，此时，DCI中的CIF比特域为保留比特状态，预定义CIF比特状态101表示原先的非授权载波调度终止，采用bitmap的方式描述新的非授权载波，所述DCI信息在PDCCH或ePDCCH专用检索空间发送，或者在约定资源中发送。
对于基站在时域连续发送UE的多个UL grant的情形，在物理层DCI中以bitmap的方式定义调度进程是否有效的指示，信令发送模块42通过物理层DCI以bitmap的方式在授权载波中指示无效的调度进程；或者，基站预先设置不同进程与物理层DCI的不同发送时刻的所述图样关系，信令发送模块42根据所述图样关系在进程对应的时刻发送物理层DCI指示所述进程无效。
或者，预先设置一个与PDCCH或ePDCCH对应的调度终止信道，所述调度终止信道用于发送调度终止的指示，信令发送模块42在授权载波中通过所述调度终止信道将调度终止的指示和/或指示调度更新的信令发送给UE。
具体的，所述调度终止信道可通过预留部分PHICH资源或物理层DCI实现。
其中，第一种方式，信令发送模块42通过预留的PHICH资源发送调度终止的指示和/或指示调度更新的信令，所述信令发送模块42在配置非授权载波时，将预留PHICH资源的参数和非授权载波的参数一起配置，且配置成预留PHICH资源参数和非授权载波具有映射关系；
信令发送模块42在指定时刻在授权载波中发送调度终止的指示和/或指示调度更新的信令，优选的，在抢占非授权载波资源未成功之后第一个子帧时刻的预留PHICH资源中、且授权载波中发送调度终止的指示和/或指示调度更新的信令；或者，在预定义的与UE进程对应的子帧时刻的预留PHICH资源中、且授权载波中发送调度终止的指示和/或指示调度更新的信 令。
另外，第二种方式，信令发送模块42通过物理层DCI发送调度终止的指示和/或指示调度更新的信令；这里，所使用的DCI原则上选择易于盲检索的格式，例如：DCI格式对应的比特数唯一；又例如，当使用DCI 3A时，设置约定的比特状态来指示调度终止和/或指示调度更新的信令；所述DCI可以使用约定的RNTI加扰，并在PDCCH或ePDCCH公共检索空间发送，或者在约定资源中发送。
所述通过物理层DCI发送调度终止的指示和/或指示调度更新的信令还包括：以bitmap的方式描述调度终止的非授权载波和/或新的非授权载波的信息，这里，所使用的DCI原则上选择易于盲检索的格式，例如：DCI格式对应的比特数唯一，比如：预定义DCI格式的前M比特(M大于等于1)携带调度终止的指示和/或新的非授权载波的信息，并预先定义非授权载波与所述M比特的映射关系。所述DCI可以使用约定的RNTI加扰，并在PDCCH或ePDCCH公共检索空间发送，或者在约定资源中发送。
所述通过物理层DCI信令发送调度终止的指示和/或指示调度更新的信令还包括：使用DCI中CIF比特域的保留状态来指示调度终止和/或指示调度更新的信令，或者，在DCI中设置专用的比特来指示调度终止和/或指示调度更新的信令；所述DCI可以使用C-RNTI加扰，并在PDCCH或ePDCCH专用检索空间发送，或者在约定资源中发送。
对于基站在时域连续发送UE的多个UL grant的情形，在物理层DCI中以bitmap的方式定义调度进程是否有效的指示，信令发送模块42通过物理层DCI以bitmap的方式在授权载波中指示无效的调度进程；或者，基站预先设置不同进程与物理层DCI的不同发送时刻的所述图样关系，信令发送模块42根据所述图样关系在进程对应的时刻发送物理层DCI指示所述进程无效。
具体的，信令发送模块42在指定时刻在授权载波中发送调度终止的指示和/或指示调度更新的信令，优选的，约定在抢占非授权载波资源未成功之后第一个子帧中、且在授权载波中发送调度终止的指示和/或指示调度更新的信令；或者，在预定义的与UE进程对应的子帧中、且在授权载波中发送调度终止的指示和/或指示调度更新的信令。
具体的，通过调度终止信道发送的调度终止的指示具体含义至少包括：中止本次调度，后续若竞争到资源则继续调度；或者，终止本次调度，后续不再继续调度。

下面结合实施例来详细说明本发明的具体应用。
实施例一
本实施例为同步HARQ下基于相对于起始调度资源位置的offset实现非授权载波的调度方法的实例。
本实施例中，假设基站和UE都为FDD制式，在子帧n时刻，基站竞争到非授权载波C1，并发送UE在该载波C1上传输的上行授权，依据FDD的定时关系，UE应在子帧n+4进行上行传输，若基站在接近n+4的子帧处(例如n+k处,k取大于等于1且小于4)未成功竞争到非授权载波C1资源(包括主系统的回归导致基站退出当前竞争到的资源，以及其他强干扰系统导致基站传输可靠性降低而退出竞争到的资源，以下都以未成功竞争到资源进行描述)，则在n+k+1时刻，基站通过物理层DCI通知新的调度资源位置相对于起始调度资源位置的offset，例如使用DCI中的CIF比特域的保留比特状态来指示所述offset，这里，可以预先定义CIF比特域的保留比特状态和offset值的映射关系，例如保留状态101，对应offset值为4，110对应offset值为8，111对应offset值为12，本实施例中假设DCI中CIF指示为110，同时，使用DCI中的CIF保留比特状态可隐含表示原先调度终止。
对于基站在时域连续发送特定UE的多个UL grant的情形，对于本实施例来说，假设基站给UE在子帧n时刻和n+1时刻连续发送了2个UL grant，为了进行区分，基站在DCI中可以利用CIF之外的可用比特以bitmap的方式定义调度进程是否有效的指示，例如，用8比特来表述不同UL进程是否有效，或者基站预定义不同进程对应的DCI的不同发送时刻，例如，预定义在子帧n发送UL grant的进程，在n+k+1时刻发送所述进程是否有效的DCI指示信令，预定义在子帧n+1发送UL grant的进程，在n+k+2时刻发送进程是否有效的DCI，且本实施例中用到的物理层DCI在基站的授 权载波上发送。
UE在约定的时刻在授权载波中接收相关DCI，优选的，UE在获取资源授权时刻(本实施例中给出的n时刻)至通过原先调度定时确定的传输时刻(本实施例中给出的n+4时刻)这段时间内监听是否有所述DCI传输；或者，UE基于预定义进程和所述DCI接收时刻的图样关系，在对应子帧(本实施例中给出的n+k+1及n+k+2时刻)监听是否有所述DCI传输，依据DCI中解析出的信息，优选的，利用DCI中CIF比特域的保留比特状态，或者利用在DCI中设置的专用比特，获知原先调度终止，并利用CIF比特域的不同的保留比特状态，或者利用DCI中预定义的bitmap映射关系获得相对于起始调度资源位置的offset值，UE在起始调度资源位置处不传输数据，在通过offset值获得的新的调度资源位置传输数据。对于本实施例，UE在原先的调度资源位置n+4子帧停止发送上行数据，等待n+16处的C1载波的竞争情况确定是否发送上行数据。
具体的，对于UE对应多个UL grant的情形，UE对于接收到的DCI信令的处理至少包括以下之一：
接收到DCI，UE对应的后续UL grant全部被终止，例如：本实施例中，UE收到在n+k+1时刻收到的DCI，则对子帧n时刻和n+1时刻连续发送的2个UL grant全部终止；
UE基于DCI中的比特指示确定相应进程的UL grant被终止(利用DCI中预定义的比特状态来指示)；
UE基于预定义的进程和DCI的接收时刻图样关系，在对应时刻接收DCI，确定对应进程的UL grant是否被终止，例如，对于预定义在子帧n发送UL grant的进程，UE在n+k+1时刻接收是否有指示所述进程无效的DCI，对于预定义在子帧n+1发送UL grant的进程，UE在n+k+2时刻接收是否有指示所述进程无效的DCI。
实施例二
本实施例为异步HARQ模式下基于相对于起始调度资源位置的offset实现非授权载波的调度方法的实例。
对于异步HARQ情形，由于offset值并没有规律，故需通知新调度资源位置处的进程号。
假设基站和UE都为FDD制式，在子帧n时刻，基站竞争到非授权载波C1，并发送UE在所述载波C1上传输的上行授权，为基站调度对时延要求比较严格的业务对应的offset发送次数上限为2，依据FDD的定时关系，UE应在子帧n+4进行上行传输，若基站在接近n+4的子帧处(例如n+k处,k取大于等于1且小于4)未成功竞争到非授权载波C1资源，则在n+k+1时刻，基站通过物理层DCI通知新的调度资源位置相对于起始调度资源位置的offset，所述DCI重用现有的DCI格式，并使用UE分配的C-RNTI加扰，此时，所述DCI中的CIF比特域利用保留比特状态表示原先调度无效，例如，预定义CIF比特域的保留比特状态101表示原先调度无效，本实施例中使用DCI Format0通过bitmap的方式来描述新的调度资源位置，将DCI Format0中5个bit设置为描述新的调度资源位置的信令，3个比特描述新的调度资源位置的进程号，其余比特继续保留发送，预先定义CIF比特域的保留比特状态和offset值的映射关系，例如00001，对应offset值为5，00010对应offset值为6，00011对应offset值为7，以此类推；本实施例中，DCI中CIF指示为101，使用的5个描述新的调度资源位置的比特状态为：00001，描述HARQ进程号的比特状态为010，所述DCI对应的PDCCH在专用搜索空间发送。
对于基站在时域连续发送特定UE的多个UL grant的情形，对于本实施例来说，假设基站给UE在子帧n时刻和n+1时刻连续发送了2个UL grant，为了进行区分，基站在DCI中可以利用CIF之外的可用比特以bitmap 的方式定义调度进程是否有效的指示，例如，用8比特表述不同进程是否有效，或者基站预定义不同进程对应的DCI的不同发送时刻，例如，预定义在子帧n发送UL grant的进程，在n+k+1时刻发送指示所述进程是否有效的DCI，预定义在子帧n+1发送UL grant的进程，在n+k+2时刻发送指示所述进程是否有效的DCI，且本实施例中用到的物理层DCI在基站的授权载波上发送。
在接收端，UE在约定的时刻在授权载波中接收相关DCI，优选的，UE在获取资源授权时刻(本实施例中给出的n时刻)至通过原先调度定时确定的传输时刻(本实施例中给出的n+4时刻)这段时间内监听是否有DCI传输；或者，UE基于预定义进程和所述信令接收时刻的图样关系，在对应子帧(本实施例中给出的n+k+1及n+k+2时刻)监听是否有DCI传输，随后，UE依据所述DCI中解析出的CIF信息确定原先调度无效，并通过预定义的比特状态和offset的映射关系，确定需要在起始调度资源位置偏移5个子帧的位置进行新的传输，利用预定义的HARQ域的状态解析出新的调度资源位置处对应的进程号为2；UE在原先的调度资源位置(n+4子帧)停止发送上行数据，等待n+10处的C1载波的竞争情况确定是否发送上行数据。
具体的，对于UE对应多个UL grant的情形，UE对于接收到的DCI的处理至少包括以下之一：
接收到DCI，UE对应的后续UL grant全部被终止，例如，本实施例中，UE收到在n+k+1时刻收到的DCI，则对子帧n时刻和n+1时刻连续发送的2个UL grant全部终止；
UE基于DCI中的比特指示确定相应进程的UL grant被终止(利用DCI中预定义的比特状态来指示)；
UE基于预定义的进程和DCI的接收时刻图样关系，在对应时刻接收DCI，确定对应进程的UL grant是否被终止，例如，对于预定义在子帧n 发送UL grant的进程，UE在n+k+1时刻接收是否有指示所述进程无效的DCI，对于预定义在子帧n+1发送UL grant的进程，UE在n+k+2时刻接收是否有指示所述进程无效的DCI。
实施例三
本实施例基于新的非授权载波的进行传输的避让策略(Cell-specific方式)。
假设基站和UE都为FDD制式。
在发送端，基站基于自身对于非授权载波的测量结果，选择合适的非授权载波作为候选非授权载波，通过这种方式形成候选非授权载波集合，假设基站基于载波聚合的方式管理、使用非授权载波，其中作为主载波的是授权载波，而作为辅载波的为非授权载波，在子帧n处，基站配置的候选非授权载波集合为S1：{C1,C2,C3}，基站从S1中选择为C1作为UE的调度载波，并通知给UE，按照FDD的调度定时，UE应在n+4处的非授权载波C1上传输上行数据，若基站在接近n+4的子帧处(例如n+k处，k取大于等于1且小于4)未成功竞争到C1资源，此时候选非授权载波集合变为S2：{C2，C3}，基站需要通知UE在n+4处终止在C1中的传输，而改为在S2中选择一个载波C2作为新的调度载波，对于该信令的发送时刻可参考实施例一中的发送时刻，基站利用物理层DCI中bitmap的方式表示上述信息，例如，重用现有DCI 1C，利用约定的RNTI加扰，预定义DCI 1C的前5比特携带新的非授权载波的信息，这里需要预先定义候选非授权载波集合中的候选非授权载波与预定义的比特的映射关系，例如：00001表示C1载波，00010表示C2载波，00100表示C3载波；基于候选非授权载波数量的变化可以调整预定义DCI 1C中的bitmap比特长度；对于本实施例，基站在DCI 1C中发送的比特为00010，其余比特作为保留比特，仍然需要发送，利用约定的RNTI对DCI 1C进行加扰后在PDCCH或ePDCCH公共搜索空间发送，基站预先 将候选非授权载波集合信息及候选非授权载波集合中的候选非授权载波与预定义的比特的映射关系通知给UE；可选的，基站在bitmap中可加入原先调度的载波的指示信息，例如bitmap为0000100010，表示原先调度的C1载波无效，应在新的非授权载波C2中传输；可选的，对于基站在时域连续发送特定UE的多个UL grant的情形，对于本实施例来说，假设基站给该UE在子帧n时刻和n+1时刻连续发送了2个UL grant，为了进行区分，基站在DCI中以bitmap的方式定义调度进程是否有效的指示，例如，用8比特来表述不同UL进程是否有效，或者基站预定义不同进程对应的DCI的不同发送时刻，例如，预定义在子帧n发送UL grant的进程，在n+k+1时刻发送指示所述进程是否有效的DCI，预定义在子帧n+1发送UL grant的进程，在n+k+2时刻发送指示所述进程是否有效的DCI，且本实施例中用到的物理层DCI在基站的授权载波上发送。
在接收端，UE在约定的时刻在授权载波中接收相关DCI信息，优选的，UE在获取资源授权时刻(本实施例中给出的n时刻)至通过原先调度定时确定的传输时刻(本实施例中给出的n+4时刻)这段时间内监听是否有DCI传输；或者，UE基于预定义进程和DCI接收时刻的图样关系，在对应子帧(本实施例中给出的n+k+1及n+k+2时刻)监听是否有DCI传输，随后，UE利用约定的RNTI在公共搜索空间正确检测出DCI 1C，获知原先调度载波不可用，基于DCI 1C中的5bit状态信息，结合候选非授权载波集合中的候选非授权载波与预定义的比特的映射关系确定新的非授权载波为C2，在子帧n+4处，UE在新的非授权载波C2中传输数据。其他的，对于UE对应多个UL grant的情形，UE的处理可参考实施例一中的方式。
UE在新的非授权载波中传输数据时，重用原先调度中指示的资源位置、MCS、进程号等参数；或者，对于新调度载波中可能出现的资源冲突，基站在利用物理层信令通知新的调度载波时，也需携带新的传输参数，例 如，利用上述DCI 1C中的部分保留比特来传递所述传输参数，UE在新的载波中利用新的传输参数进行数据传输。
实施例四
假设基站和UE都为FDD制式。
在发送端，基站基于自身对于非授权载波的测量结果，选择合适的非授权载波作为候选非授权载波，通过这种方式形成候选非授权载波集合，假设基站基于载波聚合的方式管理、使用非授权载波，其中作为主载波的是授权载波，而作为辅载波的为非授权载波，在子帧n处，基站配置的候选非授权载波集合为S1：{C1,C2,C3}，基站从S1中选择为C1作为UE的调度载波，并通知给UE，按照FDD的调度定时，UE应在n+4处的非授权载波C1上传输上行数据，若基站在接近n+4的子帧处(例如n+k处，k取大于等于1且小于4)未成功竞争到C1资源，此时候选非授权载波集合变为S2：{C2，C3}，基站需要通知UE在n+4处终止在C1中的传输，而改为在S2中选择一个载波C2作为新的调度载波，对于该信令的发送时刻可参考实施例一中的发送时刻，基站利用物理层DCI中CIF表示新的非授权载波的信息，并利用约定的RNTI加扰表示原先调度载波无效，预定义候选非授权载波集合中的载波与CIF比特的映射关系，例如：001表示C1载波，010表示C2载波，011表示C3载波；对于本实施例，基站在DCI Format0中发送的CIF比特010，其余比特作为保留比特，仍然需要发送，利用约定的RNTI对DCI Format0进行加扰后在PDCCH或ePDCCH公共搜索空间发送；关于CIF比特之外的比特，除作为保留比特发送外，也可使用bitmap的方式指示新的调度载波，例如，利用CIF域的保留比特状态，指示原先调度无效，选择DCI中的前M比特(M大于等于1)以bitmap的方式描述新的调度载波，预先定义候选非授权载波集合中的载波与预定义的比特的映射关系，此时，所述DCI使用约定的RNTI加扰，并在PDCCH或ePDCCH 公共检索空间发送，或者在约定资源中发送，当利用bitmap的方式描述新的调度载波时，可包括原先调度的载波指示。
可选的，对于基站在时域连续发送特定UE的多个UL grant的情形，对于本实施例来说，假设基站给该UE在子帧n时刻和n+1时刻连续发送了2个UL grant，为了进行区分，基站在DCI中以bitmap的方式定义调度进程是否有效的指示，例如，用8比特来表述不同UL进程是否有效，或者基站预定义不同进程对应的DCI的不同发送时刻，例如，预定义在子帧n发送UL grant的进程，在n+k+1时刻发送指示所述进程是否有效的DCI指示信令，预定义在子帧n+1发送UL grant的进程，在n+k+2时刻发送指示所述进程是否有效的DCI且本实施例中用到的物理层DCI在基站的授权载波上发送。
在接收端，UE在约定的时刻在授权载波中接收相关DCI信息，优选的，UE在获取资源授权时刻(本实施例中给出的n时刻)至通过原先调度定时确定的传输时刻(本实施例中给出的n+4时刻)这段时间内监听是否有DCI传输；或者，UE基于预定义进程和DCI接收时刻的图样关系，在对应子帧(本实施例中给出的n+k+1及n+k+2时刻)监听是否有DCI传输，随后，UE利用约定的RNTI在公共搜索空间正确检测出DCI Format0，可获知原先调度载波不可用，基于DCI Format0中的CIF状态信息，可确定新的调度载波为C2，在子帧n+4处，UE在新的调度载波C2中传输数据，或者UE利用预定的RNTI在公共搜索空间正确检测出DCI Format0，基于DCI Format0中的CIF预留状态可获知原先调度载波不可用，基于DCI中的bitmap指示信息可确定新的调度载波为C2，在子帧n+4处，UE在新的调度载波C2中传输数据。其他的，对于UE对应多个UL grant的情形，UE的处理可参考实施例一中的方式。
UE在新的非授权载波中传输数据时，重用原先调度中指示的资源位 置、MCS、进程号等参数，或者，对于新调度载波中可能出现的资源冲突，基站在利用物理层信令通知新的调度载波时，也需携带新的传输参数，例如，利用上述DCI Format0中的部分保留比特来传递所述传输参数，可采用类似DCI3/3A的方式区分不同的UE的传输参数，UE在新的载波中利用新的传输参数进行数据传输。
实施例五
本实施例基于新的非授权载波的进行传输的避让策略(UE-specific方式)。
假设基站和UE都为FDD制式。
在发送端，基站基于UE反馈的非授权载波的测量结果，为UE配置选配置多个合适的非授权载波形成候选非授权载波集合，非授权载波集合随着UE的反馈结果不同而变化；假设基站基于载波聚合的方式管理使用非授权载波，其中作为主载波的是授权载波，而作为辅载波的为非授权载波，系统可用的非授权载波有：C1、C2、C3、C4、C5，在子帧n处，基站为UE1配置的候选非授权载波集合为S1：{C1,C2,C3}，为UE2配置的候选非授权载波集合为S1：{C2,C3,C5}，基站从S1中选择C1作为UE1的调度载波，并通知给UE1，按照这种FDD的调度定时，UE1应在n+4处的非授权载波C1上传输上行数据，若基站在接近n+4的子帧处(例如n+k处，k取大于等于1且小于4)未成功竞争到C1资源，此时基站维护的UE1的候选非授权载波集合变为S^1：{C2，C3}，基站需要通知UE1在n+4处终止在C1中的传输，而改为在S2中选择一个载波C2作为新的调度载波，对于该信令的发送时刻可参考实施例一中的发送时刻，基站重用现有的DCI格式，使用UE分配的C-RNTI加扰，此时DCI中的CIF比特域利用保留比特状态表示原先调度无效，例如，预定义CIF比特状态101表示原先调度无效，并采用bitmap的方式描述被调度的新的载波，例如，重用现有DCI Format0， 利用C-RNTI加扰，预定义DCI Format0中的CIF域为101，DCI Format0的除CIF之外的前8比特新调度的载波信息，这里需要预先定于候选非授权载波集合中的载波与预定义的比特的映射关系，例如：00000001表示C1载波，00000010表示C2载波，00000100表示C3载波，对于本实施例，基站在DCI Format0中发送的比特为00000010，其余比特作为保留比特，利用UE1的C-RNTI对DCI进行加扰后在PDCCH或ePDCCH专用搜索空间发送，基站预先将候选非授权载波集合信息及候选非授权载波集合中的载波与预定义的比特的映射关系通知给UE1。
可选的，对于基站在时域连续发送UE1的多个UL grant的情形，对于本实施例来说，假设基站给UE1在子帧n时刻和n+1时刻连续发送了2个UL grant，为了进行区分，基站在DCI中以bitmap的方式定义调度进程是否有效的指示，例如，用8比特来表述不同UL进程是否有效，或者基站预定义不同进程对应的DCI的不同发送时刻，例如，预定义在子帧n发送UL grant的进程，在n+k+1时刻发送指示所述进程是否有效的DCI，预定义在子帧n+1发送UL grant的进程，在n+k+2时刻发送综上所述进程是否有效的DCI，且本实施例中用到的物理层DCI信令在基站的授权载波上发送。
在接收端，UE1在约定的时刻在授权载波中接收相关DCI信息，优选的，UE在获取资源授权时刻(本实施例中给出的n时刻)至通过原先调度定时确定的传输时刻(本实施例中给出的n+4时刻)这段时间内监听是否有DCI传输；或者，UE基于预定义进程和所述信令接收时刻的图样关系，在对应子帧(本实施例中给出的n+k+1及n+k+2时刻)监听是否有DCI传输，随后，UE1利用RNTI在专用搜索空间正确检测出DCI Format0，通过CIF的状态可获知原先调度载波不可用，并基于DCI中的8bit状态信息，结合候选非授权载波集合中的载波与预定义的比特的映射关系确定新的调度载波为C2，在子帧n+4处，UE在新的调度载波C2中传输数据。其他的， 对于UE对应多个UL grant的情形，UE的处理可参考实施例一中的方式。
UE在新的非授权载波中传输数据时，重用原先调度中指示的资源位置、MCS、进程号等参数，或者，对于新调度载波中可能出现的资源冲突，基站在利用物理层信令通知新的调度载波时，也需携带新的传输参数，例如，上述DCI为UE-specific，仅使用了CIF域和指示新载波的比特，可使用部分保留比特来传递所述UE-specific的传输参数，UE在新的载波中利用新的传输参数进行数据传输。
实施例六
假设基站和UE都为FDD制式，在子帧n时刻，基站竞争到非授权载波C1，并发送UE在该载波C1上传输的上行授权，依据FDD的定时关系，UE应在子帧n+4进行上行传输，若基站在接近n+4的子帧处(例如n+k处，k取大于等于1且小于4)未成功竞争到非授权载波C1资源，则在n+k+1时刻，基站通过预先定义的终止信道指示原先调度终止，UE应停止在原先的调度定时处(n+4子帧)进行传输，此处预定义的终止信道为预留的PHICH信道，例如基站可以预留某些上行RB不被调度和/或预留某些DMRS循环移位不使用，利用这些预留参数，预留某些PHICH资源组或者预留PHICH资源组内的某些PHICH资源，基站调度UE时避开预留PHICH资源对应的上行起始PRB索引和DMRS索引组合；基站在配置非授权载波时，将预留PHICH资源的参数和非授权载波的参数一起配置，且预留PHICH资源参数和配置的非授权载波存在映射关系，基站在预留PHICH资源中传递原先调度终止的指示信息。
可选的，对于基站在时域连续发送特定UE的多个UL grant的情形，对于本实施例来说，假设基站给该UE在子帧n时刻和n+1时刻连续发送了2个UL grant，为了进行区分，基站在预定义的和UE进程对应的子帧时刻的预留PHICH资源中发送指示进程是否无效的DCI，例如，预定义在子 帧n发送UL grant的进程，在n+k+1时刻的预留PHICH资源发送指示所述进程的是否无效的DCI，预定义在子帧n+1发送UL grant的进程，在n+k+2时刻的预留PHICH资源发送指示所述进程是否无效的DCI，且本实施例中用到的物理层DCI在基站的授权载波上发送。
接收端，UE获取非授权载波关联的预留PHICH资源的参数，在获取资源授权时刻(本实施例中给出的n时刻)至通过原先调度定时确定的传输时刻(本实施例中给出的n+4时刻)这段时间内监听是否有原先调度终止指示传输；或者，UE基于预定义进程和所述信令接收时刻的图样关系，在对应子帧(本实施例中给出的n+k+1及n+k+2时刻)监听是否有原先调度终止指示传输，若接收到原先调度终止指示，UE可获知原先调度载波不可用，UE在n+4子帧处停止发送上行数据。
具体的，对于UE对应多个UL grant的情形，UE对于接收到的终止信道传输的原先调度终止指示的处理至少包括以下之一：
接收到原先调度终止指示，UE对应的后续UL grant全部被终止，例如，本实施例中，UE在n+k+1时刻的预留PHICH资源收到原先调度终止指示，则对子帧n时刻和n+1时刻连续发送的2个UL grant全部终止；
UE基于预定义的进程和所述终止信道传输的原先调度终止指示的接收时刻图样关系，在对应时刻接收所述原先调度终止指示，确定对应进程的UL grant是否被终止，例如，对于预定义在子帧n发送UL grant的进程，UE在n+k+1时刻的预留PHICH资源接收指示所述进程是否无效的原先调度终止指示，对于预定义在子帧n+1发送UL grant的进程，UE在n+k+2时刻的预留PHICH资源接收指示所述进程是否无效的原先调度终止指示。
