Description

物理信道的资源映射方法、终端设备和网络设备 技术领域
本申请涉及通信领域，具体地，涉及一种物理信道的资源映射方法、终端设备和网络设备。
背景技术
通常，通信设备使用非授权频谱需遵循“先听后说(LBT)”原则，即通信设备在非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；如果通信设备在非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。
在工作于非授权频谱的新空口NR-U(NR based access to Unlicensed spectrum)系统中，终端设备的初始接入过程可以通过检测发现信号传输窗口(Discovery burst transmission window)中的同步信号块(Synchronization Signal/PBCH Block，SSB或SS/PBCH block)来完成。发现信号传输窗口是周期出现的，其中可包括多个用于SSB传输的候选位置。网络设备在发现信号传输窗口内发送SSB时，可以进行多次LBT尝试，并且在LBT成功后，可以通过该多个候选SSB位置中的至少一个候选位置进行SSB传输。
在实际应用中，在不同的发现信号传输窗口内，网络设备可根据LBT结果从发现信号传输窗口内的候选SSB位置中选择获得信道使用权的候选SSB位置来传输SSB，网络设备也可通过指示信息指示终端设备可能用于SSB传输的候选SSB位置。其中，实际用于SSB传输的候选SSB位置的数量小于或等于可能用于SSB传输的候选SSB位置数量。这里，如何对发现信号传输窗口中的候选SSB位置进行物理信道的资源映射，是目前需要研究的问题。

应理解，本文中术语“系统”和“网络”在本文中常可互换使用。本文中术语“和/或”用来描述关联对象的关联关系，例如表示前后关联对象可存在三种关系，举例说明，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。本文中字符“/”一般表示前后关联对象是“或”的关系。
为了清楚地阐述本申请实施例的思想，首先对通信系统中资源传输及映射进行简要描述。本申请实施例包括以下内容中的至少部分内容。
在本领域，关于NR-U系统中的SSB传输，在非授权频谱上的载波上，发现信号传输窗口的长度和/或发现信号传输窗口的周期可以是网络设备配置的。例如，对于一个服务小区，终端设备可以通过网络设备的指示信息(例如DiscoveryBurst-WindowLength-r16)来确定发现信号传输窗口的长度。可选地，指示信息指示的发现信号传输窗口的长度可以为0.5ms、1ms、2ms、3ms、4ms或5ms。如果终端设备未被网络设备配置发现信号传输窗口的长度，例如终端设备未被提供该指示信息，终端设备可以假设发现信号传输窗口的长度为一个半帧即5ms。通常，一个时隙中可以包括2个候选SSB位置，在候选SSB位置上发送的SSB的索引可以认为是候选SSB索引。在一个半帧(5ms)内可以包括的候选SSB位置的最大个数和子载波间隔相关。可选地，发现信号传输窗口的周期和SSB的周期相同。
图2给出了一个半帧内候选SSB位置的示意图，如果SSB的子载波间隔是15kHz，那么候选SSB位置的最大个数为10个，在该半帧内候选SSB位置上发送的候选SSB索引在时域上分别为从0到9；如果SSB的子载波间隔是30kHz，那么候选SSB位置的最大个数为20个，在该半帧内候选SSB位置上发送的候选SSB索引在时域上分别为 从0到19。可选地，该半帧可以为无线帧中的前半帧(前5ms)或后半帧(后5ms)。
可选地，终端设备可以根据SSB位置的准共址(Quasi co-location，QCL)关系指示信息(SSB position QCL relationship)来确定具有相同QCL假设的候选SSB位置，可将该SSB位置的QCL关系指示信息记为Q，或者说，终端设备可以根据Q来确定具有相同QCL假设的SSB索引，或者说，终端设备可以根据Q来确定SSB索引。其中，Q可以是网络设备指示的或预设的。可选地，Q用于指示一个发现信号传输窗口内网络设备可以发送的最大的SSB个数。可选地，Q的取值可以为1、2、4或8。可选地，SSB索引＝mod(候选SSB索引，Q)。例如，如果Q取值为4，在候选SSB位置10上发送的SSB的候选SSB索引为10，因此可以认为在该候选SSB位置10上发送的SSB的SSB索引为：mod(10,4)＝2。可选地，SSB索引＝mod(PBCH的DMRS序列索引，Q)。例如，如果Q取值为4，终端设备接收到一个SSB，该SSB中的PBCH的DMRS序列索引为5，那么终端设备可以认为该接收到的SSB的SSB索引为：mod(5,4)＝1。
终端设备可以通过网络设备的指示信息(例如ssb-PositionsInBurst)来确定实际发送的SSB。该指示信息可对应一个位图bitmap，其中，该bitmap中的第1个比特对应SSB索引0，该bitmap中的第2个比特对应SSB索引1，等等，以此类推。作为示例，如果该比特为0，用于指示该比特对应的SSB未被传输，如果该比特为1，用于指示该比特对应的SSB被传输。可选地，该指示信息对应的bitmap的长度为8。可选地，终端设备可以假设该bitmap中大于Q的比特位置为0。
终端设备应期望小区公共配置参数ServingCellConfigCommon中的ssb-PositionsInBurst提供的配置信息与系统消息SIB1中的ssb-PositionsInBurst提供的配置信息相同。例如，假设一个服务小区上ssb-PositionsInBurst对应的bitmap为[10100000]，Q取值为4，那么说明该服务小区上发送的SSB索引为SSB 0和SSB 2。如果SSB的子载波间隔是30kHz，发现信号传输窗口长度为5ms，如图2所示，那么可以用于SSB传输的候选SSB位置包括候选SSB位置0、2、4、6、8、10、12、14、16、18。在一个示例中，如果网络设备在候选SSB位置6处LBT成功，那么网络设备实际用于SSB传输的候选SSB位置包括候选SSB位置6和8，或者说，网络设备发送的候选SSB索引为SSB6和SSB8。在该发现信号传输窗口中，如果网络设备获得的信道占用中还包括候选SSB位置10、12、14、16、18，那么该候选SSB位置10、12、14、16、18不用于SSB发送。
基于此，对NR-U系统中发现信号传输窗口中的候选SSB位置的物理信道资源映射过程，本申请实施例提供一种物理信道的资源映射方法，应用于终端设备，参考图3，该方法包括：
S101，终端设备获取第一指示信息，所述第一指示信息用于指示第一时频资源集合；并且，第二时频资源集合包括第一物理信道对应的资源，所述第一物理信道对应于第一下行控制信息(Downlink Control Information，DCI)格式；第三时频资源集合包括所述第一时频资源集合与所述第二时频资源集合中重叠的资源；
S102，所述终端设备根据所述第一指示信息和/或所述第一DCI格式，确定所述第三时频资源集合是否用于传输所述第一物理信道。
可选地，在本申请的实施例中提到的“指示”可以是直接指示或间接指示，也可以是表示具有关联关系。例如上述的第一指示信息用于指示第一时频资源集合包括第一指示信息直接指示第一时频资源集合，或第一指示信息间接指示第一时频资源集合，或第一指示信息和第一时频资源集合相关联。
相应地，本申请实施例还提供一种物理信道的资源映射方法，应用于网络设备，参考图4，该方法包括：
S201，网络设备发送第一指示信息，所述第一指示信息用于指示第一时频资源集合；并且，第二时频资源集合包括第一物理信道对应的资源，所述第一物理信道对应于第一下行控制信息DCI格式；第三时频资源集合包括所述第一时频资源集合与所述第二时频资源集合中重叠的资源；其中，所述第一指示信息和/或所述第一DCI格式用于所述终端设备确定所述第三时频资源集合是否用于传输所述第一物理信道。
在本申请的实施例中可以认为所述的第一时频资源集合与所述的第二时频资源集合中重叠的资源为第三时频资源集合。对于该第三时频资源集合，本申请实施例的终端设备根据第一指示信息和/或第一DCI格式，来确定该第三时频资源集合是否用于传输第一物理信道，该第一DCI格式对应于该第一物理信道。由于本申请实施例并不是总是假设第一指示信息指示的资源不用于第一物理信道的传输，而是可以根据对应于该第一物理信道的第一DCI格式确定部分情况下可用于传输的时频资源，如重叠的第三时频资源集合，例如网络设备可调度该第三时频资源集合中的资源用于该第一物理信道的传输，因此本申请实施例能够在一定程度上提高资源的传输效率。

可选地，所述的SSB位置的QCL关系指示信息可通过PBCH发送。
可选地，所述的SSB位置的QCL关系指示信息可通过高层配置参数发送。
可选地，第一指示信息包括SSB位置的指示信息和/或SSB位置的准共址QCL关系指示信息，第一时频资源集合包括发现信号传输窗口内的候选同步信号块SSB位置对应的资源，第一指示信息指示第一时频资源集合，包括：SSB位置的指示信息和/或SSB位置的准共址QCL关系指示信息用于指示发现信号传输窗口内的候选同步信号块SSB位置对应的资源。如图5所示，SSB的子载波间隔是30kHz，发现信号传输窗口长度为5ms。假设SSB位置的指示信息为[11000000]，SSB位置的准共址QCL关系指示信息Q为4，那么可能用于SSB传输的候选SSB位置包括候选SSB位置0、1、4、5、8、9、12、13、16、17，也就是说，第一时频资源集合包括候选SSB位置0、1、4、5、8、9、12、13、16、17对应的资源。
可选地，第一DCI格式可以指示第二时频资源集合。例如，第一DCI格式中包括资源分配信息，该资源分配信息用于指示第一物理信道对应的时域资源和/或频域资源。终端设备在收到第一DCI格式后，可以根据第一DCI格式确定第二时频资源集合。
可选地，第三时频资源集合包括第一时频资源集合与第二时频资源集合中重叠的资 源，包括：终端设备可以根据第一时频资源集合和第二时频资源集合，确定重叠的资源属于第三时频资源集合。可选地，如果第三时频资源集合在时域上的单位为符号，在频域上的单位为RB，则如果第三时频资源集合包括第一符号上的第一RB，那么第一符号上的第一RB中的至少一个RE为重叠的资源。

可选地，在本申请的实施例中，所述的第一DCI格式包括DCI格式0_1或者DCI格式0_2，所述第一物理信道包括PUSCH。
可选地，如果该DCI格式1_1中包括所述第二指示信息，终端设备可根据所述第二指示信息确定所述第三时频资源是否用于传输所述第一物理信道；如果该DCI格式1_1中不包括所述第二指示信息，所述终端设备根据所述第一指示信息确定所述第三时频资源是否用于传输所述第一物理信道或所述终端设备根据所述第一指示信息确定所述第三时频资源不用于传输所述第一物理信道。

在本申请的一种实施例方式中，如果第一物理信道包括CRC扰码为SI-RNTI的PDCCH调度的PDSCH，且该PDCCH对应的DCI携带的系统信息指示为第四状态，则所述终端设备确定所述第二时频资源集合用于传输所述第一物理信道。可选地，所述的第四状态包括指示为“0”，或者说，系统信息指示SIB1。应理解，在步骤S101提到的终端设备接收网络设备发送的第一指示信息之前，终端设备就可能收到包括SIB1信息的PDSCH，由于这时候没有收到第一指示信息，因此在此情况下，所述终端设备可以不考虑速率匹配设置，而是将分给第一物理信道传输的资源都用于物理信道传输。
在本申请的各种实施方式或实施例中，可选地，所述第三时频资源集合在时域上包括整数个符号，且在频域上包括整数个资源块RB。因此，本申请实施例中可用于传输所述第一物理信道的资源在频域上是以RB为单位的。可选地，如果第一时频资源集合和第二时频资源集合中重叠的资源包括第一符号上的第一RE，那么第三时频资源集合中包括该第一符号上的第一RB，其中该第一RB中包括该第一RE。

另一方面，对于DCI格式1_1或DCI格式1_2调度的第一PDSCH，如果DCI格式1_1或DCI格式1_2中不包括第一速率匹配指示信息，那么终端设备根据第一指示信息指示的第一候选SSB位置进行速率匹配，即终端设备假设第一候选SSB位置对应的资源不用于第一PDSCH传输；否则，终端设备不根据第一指示信息指示的第一候选SSB位置进行速率匹配，或者说，终端设备根据第一速率匹配指示信息进行速率匹配。
以下描述基于本申请的至少部分实施例可采取的多种物理信道资源映射方式，其中，终端设备可获取第一指示信息例如ssb-PositionsInBurst，并可根据第一指示信息和/或DCI格式进行第一物理信道的资源映射。
