Description

一种UE、基站中的调度方法和装置 技术领域
本发明涉及无线通信系统中的传输方案，特别是涉及支持窄带传输的下行调度的方法和装置。
背景技术
在3GPP(3rd Generation Partner Project，第三代合作伙伴项目)RAN(Radio Access Network，无线接入网)#69次全会上，NB-IOT(NarrowBand Internet of Things，窄带物联网)被立项。NB-IOT支持3种不同的操作模式(RP-151621)：
1.独立(Stand-alone)操作，即在GERAN系统使用的频谱上部署。
2.保护带操作，即在LTE(Long Term Evolution，长期演进)载波的保护带中的未使用的资源块上部署。
3.带内操作，即在LTE载波上的资源块上部署。
进一步的，NB-IOT中，UE(User Equipment，用户设备)在上行和下行都支持180kHz(kiloHertz，千赫兹)的RF(Radio Frequency，射频)带宽，即一个PRB(Physical Resource Block，物理资源块)。
3GPP RAN1#83次会议，NB-IOT系统在上行引入了Single-tone(单频)传输和Multi-tone(多频)传输的概念。Single-tone是指UE在上行发送时，只会在一个子载波上进行传输。Multi-tone传输则沿用现在LTE(Long Term Evolution，长期演进)上行SC-FDMA(Single Carrier-Frequency Division Multiple Access，单载波频分多址)的传输方式，即在多个子载波组成的PRB(Physical Resource Block，物理资源块对)上进行传输。单频传输的一个好处就是，UE上行射频实现简单，没有PAPR(Peak to Average Power Ratio，峰值平均功率比)的问题，且实现成本低，并可以保持较低的功耗，以提高终端电池的可用时间。
对于传统的LTE系统，下行HARQ-ACK能够在PHICH(Physical Hybrid ARQ Indicator Channel，物理混合自动重传请求指示信道)或者PDCCH(Physical downlink Control Channel，物理下行控制信道)上传 输。而对于NB-IOT，一个直观的想法是尽可能的减少物理层信道的种类，以降低UE的复杂度。因此，一个可能的方案是HARQ-ACK在物理层数据信道上传输，即不会专门为了HARQ-ACK设计物理信道。基于上述方案，一个需要解决的问题是如何实现在物理层数据信道上传输的数据和HARQ-ACK的共存，即避免二者的碰撞。
发明内容
发明人通过研究发现，如果下行HARQ-ACK和下行数据在一个物理层信道上传输，如何为UE配置下行HARQ-ACK所占用的时频资源和下行数据所占用的时频资源是一个需要解决的问题。一种直观的方案是基站发送两个独立的下行信令分别指示下行HARQ-ACK所占用的时频资源和下行数据所占用的时频资源。上述直观的方案可能会导致过多的信令冗余或者资源浪费。例如下行HARQ-ACK可能仅在下行数据所占用的部分PRB中存在，即下行数据在每个PRB中所占用时频资源是变化的。因此，针对上行数据的调度信令可能需要针对每个PRB分配资源。
本发明针对上述问题提供了解决方案。需要说明的是，在不冲突的情况下，本申请的UE(User Equipment，用户设备)中的实施例和实施例中的特征可以应用到基站中，反之亦然。进一步的，在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。
本发明公开了一种支持窄带通信的UE中的方法，其中，包括如下步骤：
-步骤A.接收第一信令；
-步骤B.在目标时频资源上接收无线信号。
其中，第一信令指示第一时频资源，第一时频资源包括第二时频资源。所述目标时频资源包括所述第一时频资源中且所述第二时频资源之外的时频资源。所述目标时频资源和所述第二时频资源是正交的。第一时频资源在时域上包括T1个子帧，在频域上包括P1个子载波。第二时频资源在时域上包括所述T1个子帧中的T2个子帧。所述T1和所述P1分别是正整数，所述T2小于所述T1。
作为一个实施例，上述方法的本质是，所述UE在第一信令所指示 的第一时频资源中的部分时频资源上发送无线信号。上述方法中，第一信令不需要显式的指示所述目标时频资源，节省了信令开销。
作为一个实施例，所述无线信号对应的传输信道是DL-SCH(Downlink Shared Channel，下行共享信道)。
上述方法中，UE缺省的避免占用第二时频资源发送所述无线信号，即不需要第一信令的配置，进一步节省了第一信令的开销。然而，当第二时频资源空闲时，上述方法无法灵活的利用第二时频资源。作为一种替代方案，下述方法解决了这一问题。
本发明公开了一种支持窄带通信的UE中的方法，其中，包括如下步骤：
-步骤A.接收第一信令；
-步骤B.在目标时频资源上发送无线信号。
其中，第一信令指示第一时频资源，第一时频资源包括第二时频资源。所述目标时频资源包括所述第一时频资源中且所述第二时频资源之外的时频资源。所述第一信令指示所述目标时频资源是否包括所述第二时频资源。第一时频资源在时域上包括T1个子帧，在频域上包括P1个子载波。第二时频资源在时域上包括所述T1个子帧中的T2个子帧。所述T1和所述P1分别是正整数，所述T2小于所述T1。
作为一个实施例，上述方法中，第一信令指示所述目标时频资源是否包括第二时频资源，根据第二时频资源的使用情况确定所述无线信号是否能占用第二时频资源。相比完全不占用第二时频资源，上述方法提高了资源利用效率，代价是轻微增加了第一信令所带来的开销。
作为一个实施例，所述目标时频资源是否包括第二时频资源由第一信令中的一个比特所指示。
作为一个实施例，第一信令是物理层信令。

其中，第二信令指示第三时频资源，第二时频资源是第三时频资源中的一部分。所述第二信令是高层信令。

作为一个实施例，第三时频资源是预留给UL-SCH(Uplink Shared Channel，上行共享信道)对应的下行HARQ-ACK的时频资源。
作为一个实施例，第二信令是高层信令，第三时频资源在时域上是周期性的。
作为该实施例的一个子实施例，第三时频资源在时域上分布在正整数个时间窗中。其中，所述时间窗在时域上占用M个连续的毫秒(ms)，且所述正整数个时间窗在时域上是周期分布的。
作为一个实施例，第二信令是高层信令。
作为一个实施例，第二信令是小区公共信令。
作为一个实施例，第二信令是RRC(Radio Resource Control，无线资源控制)公共信令。
作为一个实施例，第二信令是RRC专属信令。
作为一个实施例，第二信令是物理层信令。
具体的，根据本发明的一个方面，其特征在于，所述步骤A还包括如下步骤：

作为一个实施例，所述确定第二时频资源是指UE缺省的确定第二时频资源所占用的时域和频域资源的位置。

作为该子实施例的一个附属实施例，第二时频资源在第一时频资源中的位置是固定。
作为一个实施例，上述方面中，第二时频资源在第一时频资源中的位置是固定，且UE通过固定的DL HARQ-ACK的时序关系，获取上行数据传输对应的下行反馈的发送起始子帧，此方法的好处在于，对于发送上行数据后等待HARQ-ACK反馈的用户，不需要额外的信令指示所述等待的HARQ-ACK所在的时频资源位置。
具体的，根据本发明的一个方面，其特征在于，所述步骤A还包括如下步骤A2，所述步骤B还包括如下步骤B1：
-步骤A2.发送上行信号；
-步骤B1.接收第一HARQ-ACK，第一HARQ-ACK指示所述上行信号是否被正确译码。

具体的，根据本发明的一个方面，其特征在于，第一信令是物理层信令，第一信令包括所述无线信号的调度信息。第一信令指示所述目标时频资源不包括第二时频资源且所述无线信号采用速率匹配的方案避免占用第二时频资源。
作为一个实施例，上述方面中，由于第一信令指示所述目标时频资源是否包括第二时频资源，所述UE能够采用速率匹配的方式对所述无线信号执行资源映射，避免使用打孔(Puncturing)的方式执行资源映射。相比打孔，速率匹配对应更好的接收性能。
