  • PUCCHs Physical uplink control channels
  • uplink control information (UCI) from multiple PUCCHs is multiplexed into one PUCCH.
  • the multiplexed PUCCH i.e., the PUCCH corresponding to the multiplexing result of multiple PUCCHs
  • the remaining PUCCHs are discarded, i.e., the remaining PUCCHs are not transmitted.
  • PUCCHs include: hybrid automatic repeat request-acknowledgement (HARQ-ACK), scheduling request (SR), and channel state information (CSI) PUCCHs.
  • HARQ-ACK hybrid automatic repeat request-acknowledgement
  • SR scheduling request
  • CSI channel state information
  • the UCI in at least one PUCCH is multiplexed into at least one PUSCH, and the multiplexed PUSCH (i.e., the PUSCH corresponding to the multiplexing result) is transmitted. If the UCI in a PUCCH is multiplexed into a PUSCH, then the PUCCH is not transmitted, that is, the PUCCH is discarded.
  • Time Domain Overlap In related technologies, channel multiplexing of multiple PUCCHs is only considered when they overlap in the time domain. If multiple PUCCHs do not overlap in the time domain, multiplexing is generally not considered. However, this condition does not need to be met for multiplexing between HARQ-ACK PUCCHs. For example, if multiple HARQ-ACK PUCCHs are in one slot, even if they do not overlap in the time domain, these multiple HARQ-ACK PUCCHs will be multiplexed into one HARQ-ACK PUCCH.
  • Multiplexing timeline If multiple channels overlap in time domain and satisfy the multiplexing timeline, then the multiple channels are allowed to be multiplexed into one channel.
  • a timeline that satisfies multiplexing means that, for multiple channels that overlap in the time domain, there are at least max(N1, N2) symbols between the earliest start symbol of these multiple channels and the end of the corresponding channels.
  • the multiplexed timeline is satisfied within a set of overlapping uplink (UL) channels, then that set of UL channels can be multiplexed.
  • UL uplink
  • HARQ-ACK PUCCHs instructed to be sent in the same slot will have their subsequent scheduled HARQ-ACK PUCCHs override those of the preceding scheduled HARQ-ACK PUCCHs.
  • the earlier HARQ-ACK information is placed in the later HARQ-ACK PUCCH for transmission. That is, regardless of whether these scheduled HARQ-ACK PUCCHs overlap in the time domain, the HARQ-ACK information in the same slot is multiplexed in the last scheduled HARQ-ACK PUCCH.
  • override can be performed between HARQ-ACK PUCCHs, meaning that the last scheduled HARQ-ACK PUCCH carries all the HARQ-ACK information.
  • a high-priority channel can cancel a low-priority channel. That is, when the time domains of a high-priority channel and a low-priority channel overlap, the high-priority channel is transmitted, and the low-priority channel is discarded.
  • the original timeline of the high-priority channel such as T1 or T2 needs to be extended by an extra duration to compensate for the time required for the terminal (e.g., UE) to cancel the low-priority channel.
  • CSI preparation timeline Primarily used for preparing CSI reports. In related technologies, the CSI calculation timeline is relatively long and varies depending on the circumstances. For example, semi-static CSI reports and dynamically triggered CSI reports require different processing methods.
  • timelines for signal preparation such as the timeline for PDSCH processing (for preparing HARQ-ACK), the timeline for preparing PUSCH, etc.
  • various types of timelines are satisfied by themselves. As long as multiple channels satisfy their respective types of timelines, the corresponding multiplexing process can be executed.
  • Figure 1 is a schematic diagram of the UE performing multiplexing.
  • the UE receives the physical downlink control channel (PDCCH) 1
  • the UE will receive the physical downlink shared channel (PDSCH) 1, decode it to generate the corresponding HARQ-ACK information, and simultaneously determine that PUCCH 1 is in a slot.
  • the UE needs to perform multiplexing, it needs a timeline, denoted as N1, that is, at least N1 symbols between the end of PDSCH 1 and the beginning of PUCCH 1.
  • the UE prepares PUSCH 2. If the UE needs to perform multiplexing, it needs a timeline, denoted as N2, that is, at least N2 symbols between the end of PDCCH 2 and the beginning of PUSCH 2. Furthermore, the UE discovers that PUSCH2 and PUCCH1 overlap in the time domain and satisfy the multiplexing timeline, so the UE will perform multiplexing between PUCCH1 and PUSCH2. Subsequently, the UE receives PDCCH3, and PDCCH3 schedules PDSCH3. The HARQ-ACK PUCCH of PDSCH3 is PUCCH3, and the HARQ-ACK PUCCH of PDSCH1 is PUCCH1.
  • PUCCH1 i.e., HARQ-ACK PUCCH1
  • PUCCH3 i.e., HARQ-ACK PUCCH3
  • a timeline that satisfies multiplexing means that, for multiple channels that overlap in the time domain, there are at least max(N1, N2) symbols between the earliest start symbol of these multiple channels and the end of the corresponding channels.
  • the timeline that satisfies override is that, for HARQ-ACK PUCCH1 and HARQ-ACK PUCCH2 scheduled in the same slot, the earliest start symbol of the first scheduled HARQ-ACK PUCCH1 and the last symbol of the PDCCH3 corresponding to the second scheduled HARQ-ACK PUCCH3 satisfy at least N3 symbols.
  • one processing procedure and the corresponding result is: PUCCH1 and PUSCH2 are multiplexed, the HARQ-ACK information of PDSCH1 is multiplexed in PUSCH2, the HARQ-ACK information of PDSCH3 is carried in PUCCH3, and PUCCH1 is discarded.
  • Another processing procedure and its corresponding result is as follows: multiplexing is performed between PUCCH1 and PUSCH2, but the UE then terminates this multiplexing. Then, the UE multiplexes the HARQ-ACK information of PDSCH1 in PUCCH3, and the HARQ-ACK of PDSCH3 is also carried in PUCCH3. PUCCH1 is discarded, and PUSCH2 is sent, but PUSCH2 does not carry the HARQ-ACK information of PDSCH1.

Alternatively, the first node may multiplex the multiple first channels based on a signaling instruction. For example, the first node may multiplex the multiple first channels after receiving a signaling instruction.

Similarly, after the second symbol set (symbols 7-13 in the same slot) is multiplexed through several other first channels, the first channel of the multiplexed result is transmitted from the second symbol set.

具体实施方式
下面将结合本公开中的附图，对本公开中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
需要说明的是，在本公开中，“示例性的(地)”或者“例如”等词用于描述例子、例证或说明。本公开中通过“示例性的(地)”或者“例如”等词描述的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的(地)”或者“例如”等词旨在以具体方式呈现相关概念。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，通过“第一”、“第二”等术语限定的特征可以明示或者隐含地包括一个或者更多个该特征。
在本公开的描述中，除非另有说明，“/”表示“或”的意思，例如，A/B可以表示A或B。本文中的“和/或”仅仅是用于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：仅A，A和B，仅B。此外，“至少一个”是指一个或多个，“多个”是指两个或两个以上。为了便于理解，首先对本公开实施例涉及的相关概念进行简单介绍。
1、信道复用类型。
(1)多个上行物理控制信道(physical uplink control channe，PUCCH)之间的复用。例如，将多个PUCCHs里的上行控制信息(uplink control information，UCI)信息复用到一个PUCCH里。被复用的PUCCH(也即多个PUCCHs之间的复用结果对应的PUCCH)被传输(例如，被发送到基站)，其余的PUCCH被丢弃，也即其余的PUCCH不执行发送。PUCCH包括：混合自动重传请求确认(hybrid automatic repeat request–acknowledgement，HARQ-ACK)、调度请求(scheduling request，SR)以及信道状态信息(channel state information，CSI)PUCCH。
(2)至少一个PUCCH和至少一个物理上行共享信道(physical uplink shared channel，PUSCH)之间的复用。例如，将至少一个PUCCH里的UCI复用在至少一个PUSCH里，被复用的PUSCH(也即复用结果对应的PUSCH)被传输。若一个PUCCH里的UCI被复用到了PUSCH里，则该PUCCH不被传输，也即该PUCCH被丢弃。
2、相关技术中，PUCCH之间复用、以及PUCCH与PUSCH之间复用的条件。
(1)时域重叠。在相关技术中，多个PUCCHs在时域重叠时，才考虑对多个PUCCHs进行信道复用。若多个PUCCHs在时域上不重叠，则一般不考虑复用。但是，HARQ-ACK PUCCH之间的复用无需满足这种情况。例如，若多个HARQ-ACK PUCCH在一个时隙(slot)内，即使多个HARQ-ACK PUCCH在时域上不重叠，这多个HARQ-ACK PUCCH也会被复用在一个HARQ-ACK PUCCH里。
(2)满足各种timeline。示例性地，如下是本公开实施例给出的部分timeline的示例。
a、复用的timeline：多个信道之间若时域重叠，且满足复用的timeline，则允许该多个信道复用到一个信道里。
满足复用的timeline是指，对于时域重叠的多个信道，该多个信道中的最早起始符号与该多个信道对应的信道的末尾之间满足至少max(N1，N2)个符号。
例如，复用的timeline被满足在一组重叠的上行(uplink，UL)信道，则该组UL信道可以执行复用。
b、override的timeline：被指示在同一个slot里发送的HARQ-ACK PUCCH，后调度的HARQ-ACK PUCCH会覆写(override)前面调度的HARQ-ACK PUCCH。也即，前面的HARQ-ACK信息被放置在后面的HARQ-ACK PUCCH里发送。也就是说，无论这些被调度的HARQ-ACK PUCCH是否时域重叠，同一slot里的HARQ-ACK信息被复用在最后调度的HARQ-ACK PUCCH中。
例如，override的timeline被满足，HARQ-ACK PUCCH之间就可以执行override，即最后被调度的HARQ-ACK PUCCH承载所有的HARQ-ACK信息。
c、取消的timeline：一个高优先级的信道能取消一个低优先级的信道，也即，当高优先级的信道与低优先级的信道时域重叠后，高优先级的信道被传输，低优先级的信道被丢弃。这里，高优先级的信道的原有timeline，例如T1或T2需要增加一个额外时长，以补偿终端(例如，UE)取消低优先级的信道所需要的时间。
d、CSI准备的timeline：主要用于准备CSI报告，相关技术里CSI计算的timeline相对时长比较长，并且会根据不同情况有所变化。例如，半静态CSI报告与动态触发的CSI报告就需要不同的处理方法。
e、其他各种信号准备的timeline，例如，PDSCH处理的timeline(为准备HARQ-ACK)，准备PUSCH的timeline等。
在一些实施例中，在相关技术中，各种类型的timeline是各自满足的，只要多个信道之间满足各自类型的timeline，即可执行对应的复用流程。
3、用户设备(user equipment，UE)处理信道复用的时序。
相关技术中，UE是按照时间顺序依次处理和执行复用的。例如，UE接收到对应的信令后，就会立即执行对应的复用处理，而不会有一个等待。示例性地，图1为UE执行复用的示意图。如图1所示，例如，物理下行控制信道(physical downlink control channel，PDCCH)1被UE接收后，UE会接收物理下行共享信道(physical downlink shared channel，PDSCH)1，并解码产生对应的HARQ-ACK信息，同时确定PUCCH1在一个slot里。若UE需要执行复用，则需要一个timeline，记为N1，即PDSCH1末尾到PUCCH1起始之间至少N1个符号。随后，PDCCH2被UE接收后，UE准备PUSCH2。若UE需要执行复用，则需要一个timeline，记为N2，即PDCCH2末尾到PUSCH2起始之间至少N2个符号。进一步地，UE发现PUSCH2与PUCCH1在时域重叠且满足复用的timeline，所以UE会执行PUCCH1和PUSCH2之间的复用。随后，UE接收到PDCCH3，且PDCCH3调度了PDSCH3，PDSCH3的HARQ-ACK PUCCH是PUCCH3，PDSCH1的HARQ-ACK PUCCH是PUCCH1，且PUCCH1(也即HARQ-ACK PUCCH1)和PUCCH3(也即HARQ-ACK PUCCH3)被指示到同一slot里，且满足override的timeline，所以，UE会执行PUCCH1和PUCCH3之间的override，PUCCH1里的HARQ-ACK信息被放在PUCCH3里发送，PUCCH1被丢弃。
满足复用的timeline是指，对于时域重叠的多个信道，该多个信道中的最早起始符号与该多个信道对应的信道的末尾之间满足至少max(N1，N2)个符号。
满足override的timeline是指，被指示在同一个slot里的HARQ-ACK PUCCH1和HARQ-ACK PUCCH2，先被调度的HARQ-ACK PUCCH1的最早起始符号与后被调度的HARQ-ACK PUCCH3对应的PDCCH3的末尾符号之间满足至少N3个符号。
在上述过程中，复用的timeline和override的timeline分别满足，但是UE处理过程是存在歧义的。
例如，一种处理过程和对应的结果是：PUCCH1和PUSCH2之间复用，PDSCH1的HARQ-ACK信息被复用在PUSCH2里，PDSCH3的HARQ-ACK信息被承载PUCCH3中，PUCCH1被丢弃。
例如，另一种处理过程和对应的结果是：PUCCH1和PUSCH2之间执行复用，但是UE又终止该复用。然后，UE将PDSCH1的HARQ-ACK信息承载在PUCCH3进行复用，PDSCH3的HARQ-ACK也被承载在PUCCH3里。PUCCH1被丢弃，PUSCH2被发送，但PUSCH2没有承载PDSCH1的HARQ-ACK信息。
需说明的是，上述介绍满足不同的timeline时，都使用了不同的N值来表示。通常，该N值是基于符号数量定义的，或者，也可以基于该N值换算得到实际时长。在相关技术中，不同的N值已被定义，同时也给出了基于该N值计算得到的时长。所以，下述与各种timeline相关的N值均能基于符号数被定义，或者可以基于N值换算得到实际时长。
本公开实施例提供的方法可以适用于多种通信系统并存的场景。通信系统可以为第五代(5th generation，5G)通信系统、无线局域网(wireless fidelity，Wi-Fi)系统、第三代合作伙伴计划(third generation partnership project，3GPP)相关的通信系统、未来演进的通信系统(如：第六代(6th generation，6G)通信系统等)、或多种系统融合的系统等，本公开实施例对此不予限制。
本公开实施例中通信网络(包括但不限于第三代(3th generation，3G)、4G、5G以及未来移动通信网络)的网络架构可以至少包括第一节点和第二节点。在本示例中，第一节点可以是终端侧设备(例如，包括但不限于终端)，第二节点可以是网络侧设备(例如，包括但不限于基站)。
示例性地，以第一节点为终端，第二节点为基站为例。如图2所示，为本公开实施例提供的一种通信系统的示意图。该通信系统包括终端110和基站120。终端110与基站120通信连接。
在一些实施例中，基站120可以为一个或多个，终端110也可以为一个或多个，本公开实施例不对数量进行限定。
终端110，用于响应于多个第一信道将在一个调度单元里被传输，基于预定义的第一时间线对多个第一信道进行复用，或者，基于信令指示对多个第一信道进行复用。
在一些实施例中，第一信道包括以下至少一项：至少一个上行共享信道、至少一个上行控制信道。
在一些实施例中，调度单元包括以下至少一项：时隙、子时隙、预定义正交频分复用(orthogonal frequency division multiplexing，OFDM)数量的符号集合。
在一些实施例中，一个时隙包括14个符号。一个子时隙中包括的符号数量小于14，示例性地，一个子时隙可以包括2个符号，或者包括7个符号。
在一些实施例中，第一时间线为多个第一信道中的最早起始符号之前间隔第一预设时长的时间，或者，第一时间线为调度单元的起始符号之前间隔第二预设时长的时间。第一预设时长为第一数量的正交频分复用(OFDM)符号或者绝对时长。示例性地，第一预设时长可以表示为N4。第二预设时长为第二数量的OFDM符号或者绝对时长。示例性地，第二预设时长可以表示为N5。
在一些实施例中，终端110与基站120约定，终端110对一个调度单元里的多个第一信道进行复用，应该从第一时间线对应的时间位置处开始。或者，终端110对一个调度单元里的多个第一信道进行复用，最早时间位置应该为第一时间线对应的时间位置。或者，终端110想要对一个调度单元里的多个第一信道进行复用，则终端110执行该复用的最早时间位置是第一时间线对应的时间位置。
在一些实施例中，第一时间线是一个时间窗。此时，多个第一信道被执行复用的最早时间位置在时间窗中。作为一个示例，时间窗的终止时间为多个第一信道中的最早起始符号之前至少间隔第一预设时长的时间，时间窗的起始时间为时间窗的终止时间之前间隔第三预设时长的时间。作为另一个示例，时间窗的终止时间为调度单元的起始时间之前至少间隔第二预设时长的时间，时间窗的起始时间为时间窗的终止时间之前间隔第三预设时长的时间。第三预设时长为第三数量的OFDM符号或者绝对时长。
在一些实施例中，第一时间线在第二时间与第三时间之间。此时，多个第一信道被执行复用的最早时间位置在第二时间对应的时间位置与第三时间对应的时间位置之间。作为一个示例，第二时间为多个第一信道中的最早起始符号之前至少间隔第一预设时长的时间，第三时间为第二时间之前间隔第三预设时长的时间。作为另一个示例，第二时间为调度单元的起始时间之前至少间隔第二预设时长的时间，第三时间为第二时间之前间隔第三预设时长的时间。
在一些实施例中，终端110还可以接收第二信道，并在第二信道里的信令指示被设置为开始执行复用的情况下，对调度单元里截至当前的多个第一信道进行复用。
在一些实施例中，第二信道包括下行控制信道，第二信道中的信令指示被承载在下行控制信道中的下行控制信息里。
示例性地，终端110可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端、增强现实(Augmented Reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本公开的实施例对应用场景不做限定。终端有时也可以称为用户、UE、接入终端、UE单元、UE站、移动站、移动台、远方站、远程终端、移动设备、UE终端、信道复用设备、UE代理或UE装置等，本公开实施例对此并不限定。
基站120，用于响应于多个第一信道将在一个调度单元里被接收，确定多个第一信道基于预定义的第一时间线或者基于信令指示被复用。
在一些实施例中，基站120在第一时间线之后，不再在调度单元中调度额外(新)的第一信道。也就是说，终端110不期望在第一时间线之后，再有额外(新)的第一信道被调度在该调度单元中。该额外的第一信道的优先级与该多个第一信道的优先级相同。示例性地，该额外的信道包括以下至少一项：PUCCH、承载UCI的PUSCH。
在一些实施例中，如果第一时间线是一个时间窗，则基站120在时间窗的起始位置之后，不再在调度单元中调度额外(新)的第一信道。也就是说，如果第一时间线是一个时间窗，则终端110不期望在时间窗的起始位置之后，再有额外(新)的第一信道被调度在该调度单元中。该额外的第一信道的优先级与该多个第一信道的优先级相同。示例性地，该额外的信道包括以下至少一项：PUCCH、承载UCI的PUSCH。
在一些实施例中，如果第一时间线是在第二时间与第三时间之间，则基站120在第三时间的位置之后，不再在调度单元中调度额外(新)的第一信道。也就是说，如果第一时间线是在第二时间与第三时间之间，则终端110不期望在第三时间的位置之后，再有额外(新)的第一信道被调度在该调度单元中。该额外的第一信道的优先级与该多个第一信道的优先级相同。示例性地，该额外的信道包括以下至少一项：PUCCH、承载UCI的PUSCH。
示例性地，基站120可以是长期演进(long term evolution，LTE)、长期演进增强(long term evolution advanced，LTEA)中的基站或演进型基站(evolutional node B，eNB或eNodeB)、5G网络中的基站设备、或者未来通信系统中的基站等，基站可以包括各种宏基站、微基站、家庭基站、无线拉远设备、可重构智能表面(reconfigurable intelligent surfaces，RISs)、路由器、中继、无线保真(wireless fidelity，WIFI)设备等各种网络侧设备。
需说明的是，上述场景是为了更加清楚地说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定。本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
在通信系统中，相关技术中各种类型的timeline(如复用的timeline、override的timeline、取消的timeline等)是独立满足的，没有统一协调，通信系统中的通信节点仅考虑信道复用时是否满足对应的timeline，而不协调这些timeline。因此，相关技术中多个信道之间的复用是存在问题的，如果同时出现多种情况的信道复用，只要每种情况的信道复用满足各自的timeline，通信节点即可按时间顺序执行对应的复用流程，这会使得多个信道之间的复用规则较为复杂，且复用过程容易产生歧义。针对上述问题，本公开实施例主要从时间线设置的角度考虑，简化多个信道之间的复用规则或过程。
参见图3，为根据本公开实施例的一种信道复用方法的流程图。如图3所示，本公开实施例提供的信道复用方法应用于第一节点，包括以下：S101，响应于多个第一信道将在一个调度单元里被传输，基于预定义的第一时间线对多个第一信道进行复用，或者，基于信令指示对多个第一信道进行复用。
在一些实施例中，多个第一信道包括以下至少一项：至少一个上行共享信道、至少一个上行控制信道。作为一个示例，多个第一信道可以包括信道组，该信道组包含至少一个PUCCH和至少一个PUSCH。PUSCH可以是包含UL数据的PUSCH，或者是包含UCI的PUSCH。作为另一个示例，多个第一信道可以包括多个PUCCHs，例如，包括：包含UCI的PUCCHs。作为又一个示例，多个第一信道可以包括多个PUSCHs，例如，包括：包含UCI的PUSCH、包含UL数据的PUSCH。
在一些实施例中，多个第一信道之间是时域重叠的，或者多个第一信道之间有一部分第一信道是时域重叠的，或者，多个第一信道之中至少有两个第一信道是时域重叠的。
在一些实施例中，若多个第一信道将在一个调度单元里被传输，则第一节点(例如，UE)可以基于预定义的第一时间线对多个第一信道进行复用。示例性地，第一节点可以在预定义的第一时间线的时间位置处，才开始对多个第一信道进行复用。或者，第一节点还可以基于信令指示对多个第一信道进行复用。示例性地，第一节点可以在接收到信令指示后，对多个第一信道进行复用。
可以理解的是，在一些实施例中，对应多个信道之间的复用，若多个信道之间满足多种类型的timeline，但由于每种情况仅仅考虑各自对应的timeline是否满足，而不协调这些timeline，因此信道之间的复用规则比较复杂。本公开实施例提供的方法在多个第一信道将在一个调度单元里被传输的情况下，第一节点通过预定义的第一时间线或者信令指示对多个第一信道进行复用，可以有效地协调不同类型的信道复用，减少不同信道复用规则之间的冲突和歧义，避免因规则不协调导致的通信中断或错误，进而保障信息传输的稳定性。并且，基于第一时间线或者信令指示对多个第一信道进行复用，可以简化第一节点对信道复用规则的管理，使得第一节点等其他通信节点更容易理解和执行复用。
此外，预定义的第一时间线或信令指示为信道复用提供了更多的灵活性，可以基于实际的通信需求调整第一时间线或者信令指示，进而合理地分配通信资源，提高资源的利用率。
在一些实施例中，调度单元包括以下至少一项：时隙、子时隙、预定义OFDM数量的符号集合。
在一些实施例中，一个时隙包括14个符号。一个子时隙中包括的符号数量小于14。示例性地，一个子时隙可以包括2个符号，或者包括7个符号。
在一些实施例中，如果子时隙被配置，则时隙包含的符号数量等于子时隙的符号数量。示例性地，若子时隙被配置为4个符号，则此时时隙包含的符号数量也为4个符号。
在一些实施例中，上述预定义OFDM数量的符号集合可以为预定义的。可以预定义符号集合包含的符号数量，以及符号集合中符号的位置(或索引)。
作为一个示例，第二节点和第一节点可以预定义一个slot里的符号0-符号6为一个符号集合，符号7-符号13为另一个符号集合。这样，一个slot里存在两个符号集合，第一节点在每个符号集合内都可以对多个第一信道进行复用。
作为另一个示例，第二节点和第一节点可以预定义一个slot里的符号0-符号14为一个符号集合。
作为又一个示例，第二节点和第一节点可以预定义多个slot里的符号组成一个符号集合。
作为又一个示例，第二节点和第一节点可以预定义一个slot里的符号1-符号10是一个符号集合，符号11-符号13为另一个符号集合。
可以理解的是，本公开实施例提供的方法可以基于不同的通信需求和场景，预先定义不同大小的符号集合，以适应不同的数据传输速率和信道条件。通过预定义不同大小的符号集合，可以更精细地调整信道的带宽和功率分配，增加了灵活性的同时，还可以优化整体的资源利用效率。
在一些实施例中，上述预定义OFDM数量的符号集合还可以是基于信令配置的。用于配置符号集合的信令可以指示符号集合包含的符号数量，以及符号集合中符号的位置(或索引)。
作为第一个示例，用于配置符号集合的信令可以指示一个slot中包含的一个或多个符号集合。作为另一个示例，用于配置符号集合的信令可以指示一个或多个符号集合。作为又一个示例，用于配置符号集合的信令还可以指示多个slot的符号组成一个符号集合。
可以理解的是，本公开实施例提供的方法中符号集合的大小可以基于信令配置，基站可以基于实时的信道状况和网络负载动态地调整符号集合的大小，以优化数据传输的性能，提高传输的可靠性和效率。
可以理解的是，一个slot可以包含多个符号集合，每个符号集合都可以独立执行信道复用，从而可以增加信道在一个slot里传输的机会。例如，第一个符号集合(一个slot里的符号0-符号6)通过多个第一信道复用后，复用结果的第一信道从第一个符号集合里被传输。第二个符号集合(该slot的符号7-符号13)通过另外的多个第一信道复用后，复用结果的第一信道从第二个符号集合被传输。这样就有2次信道传输机会，且由于第一个符号集合里的符号是该slot靠前的符号，第一次的传输时间能被提前，实现了更小的执行复用的颗粒度，提高了数据传输的效率和资源利用率。
在一些实施例中，上述用于配置符号集合的信令可以通过不同的信令传输。
作为一个示例，用于配置符号集合的信令可以通过RRC(Radio Resource Control，无线资源控制)信令被传输。示例性地，用于配置符号集合的信令可以在PUCCH相关的配置参数(PUCCH-config)/PUSCH相关的配置参数(PUSCH-config)里，且该PUCCH-config提供PUCCH资源配置和PUCCH资源集合配置，PUSCH-config提供PUSCH资源配置和PUSCH资源集合配置。
作为另一个示例，用于配置符号集合的信令可以通过PDCCH里的DCI(Downlink Control Information，下行控制信息)被传输，例如，用于配置符号集合的信令可以被传输在调度PDSCH的DCI里。
在一些实施例中，在一个调度单元(例如，一个符号集合)里，第一时间线为多个第一信道中的最早起始符号之前间隔第一预设时长的时间。
在一些实施例中，第一预设时长为第一数量的正交频分复用(OFDM)符号或者绝对时长。也就是说，可以将第一数量的OFDM符号换算为绝对时长来表示第一预设时长。示例性地，第一数量可以为5，第一预设时长可以表示为N4。
示例性地，图4为第一时间线的示意图。如图4所示，多个第一信道包括：PUCCH1、PUSCH2和PUCCH3。PUCCH1对应的下行信道为PDCCH1，且PDCCH1调度了PDSCH1。PUCCH2对应的下行信道为PDCCH2。PUCCH3对应的下行信道为PDCCH3，且PDCCH3调度了PDSCH3。N1是解码PDSCH1和PDSCH3准备HARQ-ACK的时长。N2是准备PUSCH2的时长。N3是同一时隙里的HARQ-ACK PUCCH之间执行override的时长。从图4中可以看出，多个第一信道中的最早起始符号为PUSCH2的起始符号，则第一时间线为PUSCH的起始符号之前间隔N4的时间。
在一些实施例中，N4的值可以被配置。示例性地，N4的值可以被第二节点(例如，基站)配置。例如，第二节点可以基于时域重叠的复用传输的时间要求(例如，复用的timeline)、覆写的复用传输的时间要求(例如，override的timeline)、上行共享信道的准备时长(例如，准备PUSCH的时长)、下行共享信道的处理时长(例如，处理PDSCH的时长)、信道状态信息的准备时长(例如，准备CSI的时长)等，从中选择最大的时长作为N4的值。
可以理解的是，本公开实施例提供的方法中，第一预设时长N4可以被灵活配置，提高了信道复用的灵活性。
在一些实施例中，在一个调度单元(例如，一个符号集合)里，第一时间线为调度单元的起始符号之前间隔第二预设时长的时间。
在一些实施例中，第二预设时长为第二数量的OFDM符号或者绝对时长。也就是说，可以将第二数量的OFDM符号换算为绝对时长来表示第二预设时长。示例性地，第二数量可以为6，第二预设时长可以表示为N5。
示例性地，图5为第一时间线的示意图。如图5所示，多个第一信道包括：PUCCH1、PUSCH2和PUCCH3。PUCCH1对应的下行信道为PDCCH1，且PDCCH1调度了PDSCH1。PUCCH2对应的下行信道为PDCCH2。PUCCH3对应的下行信道为PDCCH3，且PDCCH3调度了PDSCH3。N1是解码PDSCH1和PDSCH3准备HARQ-ACK的时长。N2是准备PUSCH2的时长。N3是同一时隙里的HARQ-ACK PUCCH之间执行override的时长。从图5中可以看出，第一时间线为调度单元的起始符号之前间隔N5的时间。
在一些实施例中，N5的值可以被配置。示例性地，N5的值可以被第二节点(例如，基站)配置。例如，第二节点可以基于时域重叠的复用传输的时间要求(例如，复用的timeline)、覆写的复用传输的时间要求(例如，override的timeline)、上行共享信道的准备时长(例如，准备PUSCH的时长)、下行共享信道的处理时长(例如，处理PDSCH的时长)、信道状态信息的准备时长(例如，准备CSI的时长)等，从中选择最大的时长作为N5的值。
可以理解的是，本公开实施例提供的方法中，第二预设时长N5可以被灵活配置，提高了信道复用的灵活性。
在一些实施例中，第一时间线对应的时间位置作为多个第一信道被执行复用的最早时间位置。示例性地，第二节点与第一节点约定，第一节点对调度单元(例如，一个时隙)里的多个第一信道执行复用，应该从第一时间线对应的时间位置开始。或者，第一节点对调度单元里的多个第一信道执行复用的最早时间位置为第一时间线对应的时间位置。
在一些实施例中，第二节点在第一时间线对应的时间位置之后，不再在调度单元中调度额外的信道，也就是说，第一节点不期望在第一时间线对应的时间位置之后，再有额外的信道被调度在调度单元中。该额外的信道的优先级与多个第一信道的优先级相同。示例性地，该额外的信道至少包含PUCCH，或者承载UCI的PUSCH。
在一些实施例中，第一时间线用于指示第一节点执行多个第一信道之间的复用时，最早应该从第一时间线对应的时间位置处开始。或者，第一时间线用于指示：第一节点不期望在该第一时间线对应的时间位置之后，与多个第一信道具有相同优先级的信道被调度在调度单元里。
可以理解的是，本公开实施例提供的方法通过预定义的第一时间线，可以明确第二节点在第一时间线对应的时间位置之前进行更有效的资源调度，而避免在第一时间线之后还需要调度和处理额外的复用。
在一些实施例中，满足第一时间线，是指在调度单元里的多个第一信道之前执行复用，该第一时间线能够为第一节点提供足够的时间来执行该复用。也就是说，第一时间线对应的时间位置与多个第一信道中的最早起始符号之间的时间间隔大于或等于第一节点执行该复用所需要的时长。
在一些实施例中，多个第一信道对应的信道(也即能够触发终端调度多个第一信道的第二信道，例如PUCCH对应的PDSCH)或信号的最晚结束位置不在第一时间线对应的时间位置之后。也就是说，多个第一信道对应的信道(也即第二信道)或信号的最晚结束位置在第一时间线对应的时间位置之前。
在一些实施例中，上述第二信道包括下行控制信道，第二信道中的信令指示被承载在下行控制信道中的下行控制信息里。
在一些实施例中，第一节点不期望被执行复用的多个第一信道对应的信道不满足第一时间线。
可以理解的是，本公开实施例提供的方法中，通过确定第一时间线对应的时间位置，可以为第一节点提供一个清晰的复用执行的期限，减少了关于执行复用的不确定性和歧义。
在一些实施例中，第一时间线是一个时间窗。时间窗的终止时间为多个第一信道中的最早起始符号之前至少间隔第一预设时长N4的时间，时间窗的起始时间为时间窗的终止时间之前间隔第三预设时长的时间。N4为执行该多个第一信道所需要的时长。时间窗的长度能被配置或预定义。
在一些实施例中，时间窗的终止时间在第一时间线对应的时间位置上，该第一时间线对应的时间位置被作为时间窗的最晚结束位置。也就是说，时间窗的终止时间不能在第一时间线对应的时间位置之后。
在一些实施例中，第一时间线对应的时间位置为多个第一信道中的最早起始符号之前间隔第一预设时长的时间。将第一时间线对应的时间位置向前间隔第三预设时长，这样即可形成一个执行复用的时间窗(也可以叫做时间段)。第三预设时长为第三数量的OFDM符号或者绝对时长。也就是说，可以将第三数量的OFDM符号换算为绝对时长来表示第三预设时长。示例性地，第三数量可以为6，第三预设时长可以表示为W。
示例性地，图6为时间窗的示意图。如图6所示，多个第一信道包括：PUCCH1、PUSCH2和PUCCH3。PUCCH1对应的下行信道为PDCCH1，且PDCCH1调度了PDSCH1。PUCCH2对应的下行信道为PDCCH2。PUCCH3对应的下行信道为PDCCH3，且PDCCH3调度了PDSCH3。N1是解码PDSCH1和PDSCH3准备HARQ-ACK的时长。N2是准备PUSCH2的时长。N3是同一时隙里的HARQ-ACK PUCCH之间执行override的时长。从图6中可以看出，多个第一信道中的最早起始符号为PUSCH2的起始符号，则第一时间线为PUSCH的起始符号之前间隔N4的时间。此时，将第一时间线对应的时间位置向前间隔W，即可确定执行复用的时间窗。多个第一信道被执行复用最早从时间窗里开始，例如，时间窗的起始位置是最早执行该复用的位置。
在一些实施例中，调度单元可以为一个符号集合。可以将多个第一信道中的最早起始符号向前间隔N4时长的时间确定为该符号集合里多个第一信道对应的第一时间线。第一时间线对应的时间位置向前W时长，这样即可形成一个执行复用的时间窗(段)。
在一些实施例中，W的值可以被配置。示例性地，W的值可以被第二节点(例如，基站)配置。
在一些实施例中，第二节点配置第三预设时长W，时间窗的终止时间可以早于一个调度单元(例如，一个符号集合)中多个第一信道中的最早起始符号之前间隔第一预设时长的时间。示例性地，图7为时间窗的示意图。如图7所示，多个第一信道包括：PUCCH1、PUSCH2和PUCCH3。PUCCH1对应的下行信道为PDCCH1，且PDCCH1调度了PDSCH1。PUCCH2对应的下行信道为PDCCH2。PUCCH3对应的下行信道为PDCCH3，且PDCCH3调度了PDSCH3。N1是解码PDSCH1和PDSCH3准备HARQ-ACK的时长。N2是准备PUSCH2的时长。N3是同一时隙里的HARQ-ACK PUCCH之间执行override的时长。将时间窗的终止时间向前间隔W，即可确定执行复用的时间窗。从图7中可以看出，时间窗的起始时间不在多个第一信道对应的信道(也即第二信道)中，任意一个第二信道的终止符号之后间隔N1或N2的时间。
可以理解的是本公开实施例提供的方法中，第三预设时长W可以被灵活配置，提高了信道复用的灵活性。
在一些实施例中，第一时间线是一个时间窗。时间窗的终止时间为调度单元的起始时间之前至少间隔第二预设时长N5的时间，时间窗的起始时间为时间窗的终止时间之前间隔第三预设时长的时间。
在一些实施例中，时间窗的终止时间在第一时间线对应的时间位置上，该第一时间线对应的时间位置被作为时间窗的最晚结束时间。也就是说，时间窗的终止时间不能在第一时间线对应的时间位置之后。
在一些实施例中，第一时间线对应的时间位置为调度单元的起始符号之前间隔第二预设时长的时间。将第一时间线对应的时间位置向前间隔第三预设时长，这样即可形成一个执行复用的时间窗(也可以叫做时间段)。
在一些实施例中，调度单元可以为一个符号集合。可以将调度单元(例如，一个符号集合)起始符号向前间隔N5时长的时间确定为该符号集合里多个第一信道的第一时间线。第一时间线对应的时间位置向前W时长，这样即可形成一个执行复用的时间窗(段)。
示例性地，图8为时间窗的示意图。如图8所示，多个第一信道包括：PUCCH1、PUSCH2和PUCCH3。PUCCH1对应的下行信道为PDCCH1，且PDCCH1调度了PDSCH1。PUCCH2对应的下行信道为PDCCH2。PUCCH3对应的下行信道为PDCCH3，且PDCCH3调度了PDSCH3。N1是解码PDSCH1和PDSCH3准备HARQ-ACK的时长。N2是准备PUSCH2的时长。N3是同一时隙里的HARQ-ACK PUCCH之间执行override的时长。从图8中可以看出，调度单元的起始符号间隔第二预设时长的时间点即为第一时间线对应的时间位置。将第一时间线对应的时间位置向前间隔W，即可确定执行复用的时间窗。
在一些实施例中，时间窗的终止时间在第一时间线对应的时间位置上，该第一时间线对应的时间位置被作为时间窗的最晚结束时间。也就是说，时间窗的终止时间不能在第一时间线对应的时间位置之后。
在一些实施例中，第二节点配置第三预设时长W，时间窗的终止时间可以早于调度单元(例如，一个符号集合)的起始符号之前间隔第二预设时长的时间。示例性地，图9为时间窗的示意图。如图9所示，多个第一信道包括：PUCCH1、PUSCH2和PUCCH3。PUCCH1对应的下行信道为PDCCH1，且PDCCH1调度了PDSCH1。PUCCH2对应的下行信道为PDCCH2。PUCCH3对应的下行信道为PDCCH3，且PDCCH3调度了PDSCH3。N1是解码PDSCH1和PDSCH3准备HARQ-ACK的时长。N2是准备PUSCH2的时长。N3是同一时隙里的HARQ-ACK PUCCH之间执行override的时长。从图9中可以看出，时间窗的起始时间不在多个第一信道对应的信道(也即第二信道)中，任意一个第二信道的终止符号之后间隔N1或N2的时间。将时间窗的终止时间向前间隔W，即可确定执行复用的时间窗。
在一些实施例中，上述时间窗的起始时间和终止时间可以灵活配置。示例性地，时间窗的终止时间可以被配置在第一时间线对应的时间位置之前。也就是说，时间窗的终止时间可以被配置在第一时间线对应的时间位置之前的任意位置。
可以理解的是，本公开实施例提供的方法中，第一时间线是一个时间窗，可以限制复用操作的时间窗口，使得资源调度更加精准和快速，提高频谱资源的利用效率。此外，由于时间窗的终止时间可以被配置在第一时间线对应的时间位置之前的任意位置，因此可以基于通信系统的需求和实际的资源分配，对时间窗的终止时间进行配置，提高了系统的灵活性。
在一些实施例中，多个第一信道被执行复用的最早时间位置在时间窗中。示例性地，第二节点与第一节点约定，第一节点对调度单元(例如，一个时隙)里的多个第一信道执行复用，应该从时间窗里开始。或者，第一节点对调度单元里的多个第一信道执行复用的最早时间位置在该时间窗里。
在一些实施例中，第二节点在时间窗的起始时间开始之后，不再在调度单元中调度额外(新)的第一信道，也就是说，第一节点不期望在时间窗的起始时间之后，再有额外(新)的第一信道被调度在调度单元中。该额外(新)的第一信道的优先级与多个第一信道的优先级相同。示例性地，该额外(新)的第一信道至少包含PUCCH，或者承载UCI的PUSCH。
可以理解的是，本公开实施例提供的方法中，第二节点在时间窗的起始时间开始之后，不再在调度单元中调度额外的信道(额外的信道是指新的第一信道)，可以避免在时间窗的起始时间开始之后，出现资源分配上的冲突，保障信道复用不会与其他的操作相重叠，进而保障信道复用的稳定性。
在一些实施例中，第一时间线在第二时间与第三时间之间。第二时间为多个第一信道中的最早起始符号之前至少间隔第一预设时长的时间，第三时间为第二时间之前间隔第三预设时长的时间。
在一些实施例中，第一时间线在第二时间与第三时间之间，第二时间为调度单元的起始时间之前至少间隔第二预设时长的时间，第三时间为第二时间之前间隔第三预设时长的时间。
在一些实施例中，多个第一信道被执行复用的最早时间位置在第二时间对应的时间位置与第三时间对应的时间位置之间。
在一些实施例中，如图10所示，上述基于信令指示对多个第一信道进行复用，例如，可实现为：S201和S202。
在S201中，接收第二信道。
在一些实施例中，第二信道包括下行控制信道。示例性地，第二信道可以是触发第一信道(例如，PUCCH、PUSCH)的PDCCH。
在一些实施例中，多个第一信道可以时域重叠，或者在时域上不重叠。
在S202中，在第二信道里的信令指示被设置为开始执行复用的情况下，对调度单元里截至当前的多个第一信道进行复用。
在一些实施例中，第二信道中的信令指示被承载在下行控制信道中的下行控制信息里。示例性地，若第二信道为PDCCH，则第二信道中的信令指示可以被承载在PDCCH的DCI中。
示例性地，第二节点通过PDCCH调度PDSCH，或者通过PDCCH调度PUSCH时，可以在PDCCH的DCI中引入一个信令指示。该信令指示用于指示第一节点在接收到该信令指示后，是否对调度单元里的多个第一信道进行复用。多个第一信道包括以下至少一项：PUCCH、PUSCH。PUSCH可以是承载UCI的PUSCH。第一节点从PDCCH中接收DCI，并根据DCI中的信令指示，确定开始执行，或者不执行多个第一信道之间的复用。当信令指示被设置为开始执行复用时，第一节点对调度单元里截止当前的多个第一信道进行复用。
在一些实施例中，上述DCI可以是没有调度DL(Downlink，下行)数据或UL数据的DCI。
在一些实施例中，若第二信道中的信令指示(也即第二信道中的DCI中的信令指示)被设置为开始执行复用，则第一节点对调度单元里截至当前的多个第一信道进行复用。或者，第一节点对调度单元里截至当前的多个第一信道进行复用，且不期望之后在调度单元里再被调度新的第一信道并与该多个第一信道中的任意一个或多个信道之间执行复用。
可以理解的是，为了简化信道复用的规则，需要第一节点(例如，UE)和第二节点(例如，基站)对执行复用的时机的理解保持一致。本公开实施例提供的方法通过基于信令指示确定对多个第一信道进行复用，可以防止多个第一信道开始执行复用之后，第二节点又调度新的第一信道，且该新的第一信道与原有的多个第一信道在时域重叠而再执行复用。从而，简化多个第一信道之间的复用规则，减少多个信道之间的复用歧义，降低复用的复杂性。
在一些实施例中，如图11所示，上述基于信令指示对多个第一信道进行复用，还包括：S203。
在S203中，在第二信道里的信令指示被设置为不开始执行复用的情况下，对调度单元里截至当前的多个第一信道不进行复用。
在一些实施例中，若第二信道里的信令指示(例如，第二信道中的DCI内的信令指示)被设置为不开始执行复用，则第一节点需要等待第二节点进一步的指示。
在一些实施例中，第一节点基于信令指示的取值，确定开始执行复用，或者不执行多个第一信道之间的复用。示例性地，信令指示为0时，表示不开始进行复用；信令指示为1时，表示开始执行复用。
示例性地，图12为信令指示的示意图。如图12所示，信令指示为0，表示对调度单元里截至当前的多个第一信道不进行复用。信令指示为1，表示对调度单元里截至当前的多个第一信道进行复用。第二节点根据规划的调度需求，在PDCCH1的DCI中将信令指示设置为0，表示不期望第一节点对调度单元里截至当前的多个第一信道进行复用。第二节点在PDCCH2的DCI中将信令指示设置为0，表示不期望第一节点对调度单元里截至当前的多个第一信道进行复用。第二节点在PDCCH3的DCI中将信令指示设置为1，表示要求第一节点对调度单元里截至当前的多个第一信道进行复用。第二节点在PDCCH3后，不会再在调度单元里调度额外的信道。
第一节点接收到PDCCH1后，基于信令指示为0，第一节点暂不开始对调度单元里截至当前的多个第一信道进行复用。第一节点接收到PDCCH2后，基于信令指示为0，第一节点仍然暂不开始对调度单元里截至当前的多个第一信道进行复用。第一节点接收到PDCCH3后，基于信令指示为1，第一节点开始对调度单元里截至当前的多个第一信道进行复用。
在一些实施例中，第一节点还可以基于是否存在信令指示，确定开始执行复用，或者不开始执行多个第一信道之间的复用。作为一个示例，若信令指示存在于上述DCI中(也即信令指示存在于第二信道中)，则表示第一节点在接收到DCI之后对调度单元里截至当前的多个第一信道不进行复用。若DCI中不存在信令指示(也即第二信道中不包括信令指示)，则表示第一节点在接收到DCI之后对调度单元里截至当前的多个第一信道进行复用。作为另一个示例，若信令指示存在于上述DCI中(也即信令指示存在于第二信道中)，则表示第一节点在接收到DCI之后对调度单元里截至当前的多个第一信道进行复用。若DCI中不存在信令指示(也即第二信道中不包括信令指示)，则表示第一节点在接收到DCI之后对调度单元里截至当前的多个第一信道不进行复用。
可以理解的是，本公开实施例提供的方法中，通过基于信令指示的取值，确定是否开始执行复用，可以为第一节点提供一个清晰的执行复用的信号，简化了第一节点的决策过程，减少了因复用时机不确定而产生的歧义。此外，基站可以根据实时的网络状态和需求，通过信令灵活地控制复用过程，提高网络资源调度的效率。
在一些实施例中，第一节点不期望DCI所在的PDCCH在多个第一信道中的最早起始符号之前间隔第一预设时长的时间之后被接收。也就是说，上述DCI所在的PDCCH应该被传输在多个第一信道中的最早起始符号之前间隔第一预设时长的时间之前。也即，上述DCI所在的PDCCH应该在第一时间线对应的时间位置之前被传输，或者不能在第一时间线对应的时间位置之后被传输。此时，第一时间线为多个第一信道中的最早起始符号之前间隔第一预设时长的时间。
在一些实施例中，第一节点不期望DCI所在的PDCCH在调度单元的起始符号之前间隔第二预设时长的时间之后被接收。也就是说，DCI所在的PDCCH应该被传输在调度单元的起始符号之前间隔第二预设时长的时间之前。也即，DCI所在的PDCCH应该在第一时间线对应的时间位置之前被传输，或者不能在第一时间线对应的时间位置之后被传输。此时，第一时间线为调度单元的起始符号之前间隔第二预设时长的时间。
在一些实施例中，第二节点和第一节点可以预先定义，若第一节点直到第一时间线对应的时间位置处仍未接收到指示开始执行复用的信令指示，则第一节点基于第一时间线对调度单元里截至当前的多个第一信道进行复用。
可以理解的是，本公开实施例提供的方法，通过预先定义：若第一节点直到第一时间线对应的时间位置处仍未接收到指示开始执行复用的信令指示，则第一节点基于第一时间线对调度单元里截至当前的多个第一信道进行复用，可以防止DCI漏检，即第二节点发送了该DCI，但是UE并未收到。此外，本公开实施例提供的方法，即使在DCI传输可能失败的情况下，第一节点也可以基于第一时间线及时进行复用，保证了数据传输的连续性和及时性。而且，通过在第一时间线后自动执行复用，减少了因等待DCI而导致的数据重传，从而提高了频谱资源的利用率。
在一些实施例中，对于一个调度单元里的多个第一信道，若第二信道中的DCI被第一节点接收，且DCI中的信令指示被设置为开始执行复用，则第一节点不期望再接收下一个DCI，且该下一个DCI中的信令指示被设置为对调度单元里截至当前的多个第一信道进行复用。
在一些实施例中，对于一个调度单元里的多个第一信道，若第二信道中的DCI被第一节点接收，且DCI中的信令指示被设置为开始执行复用，则第一节点可以再接收下一个DCI，且该下一个DCI中的信令指示被设置为对调度单元里的多个第一信道进行复用。若该下一个DCI在调度单元中没有触发新的第一信道，第一节点则考虑该下一个DCI仍然是指示第一节点对调度单元里截至当前的多个第一信道进行复用。或者，该下一个DCI所触发的新的第一信道在另一个调度单元里。
在一些实施例中，第二节点和第一节点可以预先定义，若第一节点第一次接收到信令指示，且该信令指示被设置为开始执行复用，则第一节点对调度单元里截至当前的多个第一信道进行复用。之后，若第一节点继续接收DCI，且该DCI里的信令指示被设置为开始执行复用，则第一节点对之前一次执行复用后的复用结果对应的第一信道和截至当前调度单元里已有的但未参与复用的第一信道之间执行复用。复用结果对应的第一信道是指，多个第一信道被复用后的信道。
在一些实施例中，第二节点和第一节点可以预先定义，若第一节点第一次接收到信令指示，且该信令指示被设置为开始执行复用，则第一节点对调度单元里截至当前的多个第一信道进行复用。之后，第一节点第二次接收到DCI，且该DCI里的信令指示被设置为开始执行复用，则第一节点对第一次DCI之后且截至当前的多个第一信道进行复用。
基于本公开实施例提供的信道复用方法，在多个第一信道将在一个调度单元里被传输的情况下，第一节点通过预定义的第一时间线或者信令指示对多个第一信道进行复用，可以有效地协调不同类型的信道复用，减少不同信道复用规则之间的冲突和歧义，避免因规则不协调导致的通信中断或错误，进而保障信息传输的稳定性。并且，基于第一时间线或者信令指示对多个第一信道进行复用，可以简化第一节点对信道复用规则的管理，使得第一节点等其他通信节点更容易理解和执行复用。
此外，预定义的第一时间线或信令指示为信道复用提供了更多的灵活性，可以基于实际的通信需求调整第一时间线或者信令指示，进而合理地分配通信资源，提高资源的利用率。
参见图13，为根据本公开实施例的一种信道复用方法的流程图。如图13所示，本公开实施例提供的信道复用方法应用于第二节点，包括以下：S301，响应于多个第一信道将在一个调度单元里被接收，确定多个第一信道基于预定义的第一时间线或者基于信令指示被复用。
在一些实施例中，多个第一信道中包括以下至少一项：至少一个上行共享信道、至少一个上行控制信道。
需说明的是，多个第一信道的内容可参考上述S101中的描述，本公开实施例在此不再赘述。
在一些实施例中，调度单元包括以下至少一项：时隙、子时隙、预定义OFDM数量的符号集合。
需说明的是，调度单元的内容可参考上述S101中的描述，本公开实施例在此不再赘述。
可以理解的是，本公开实施例提供的信道复用方法，在多个第一信道将在一个调度单元里被接收的情况下，第二节点确定多个第一信道基于预定义的第一时间线或者基于信令指示被复用，可以有效地协调不同类型的信道复用，减少不同信道复用规则之间的冲突和歧义，避免因规则不协调导致的通信中断或错误，进而保障信息传输的稳定性。并且，确定多个第一信道基于预定义的第一时间线或者基于信令指示被复用，可以简化第二节点对信道复用规则的管理，使得第二节点更容易理解复用规则。
此外，预定义的第一时间线或信令指示为信道复用提供了更多的灵活性，可以基于实际的通信需求调整第一时间线或者信令指示，进而合理地分配通信资源，提高资源的利用率。
在一些实施例中，预定义的第一时间线为多个第一信道中的最早起始符号之前间隔第一预设时长的时间。
在一些实施例中，第一预设时长为第一数量的OFDM符号或者绝对时长。
需说明的是，第一时间线的内容和第一预设时长的内容可参考上述实施例中的描述，本公开实施例在此不再赘述。
在一些实施例中，预定义的第一时间线为调度单元的起始符号之前间隔第二预设时长的时间。
在一些实施例中，第二预设时长为第二数量的OFDM符号或者绝对时长。
需说明的是，第一时间线的具容和第二预设时长的内容可参考上述实施例中的描述，本公开实施例在此不再赘述。
在一些实施例中，第一时间线对应的时间位置作为多个第一信道被执行复用的最早时间位置。
可以理解的是，本公开实施例提供的方法中，通过确定第一时间线对应的时间位置，可以为第一节点提供一个清晰的复用执行的期限，减少了关于执行复用的不确定性和歧义。此外，通过预定义的第一时间线，可以使得第二节点明确在第一时间线对应的时间位置之前进行更有效的资源调度，而避免在第一时间线之后还需要调度和处理额外的复用。
在一些实施例中，预定义的第一时间线是一个时间窗，时间窗的终止时间为多个第一信道中的最早起始符号之前至少间隔第一预设时长的时间，时间窗的起始时间为时间窗的终止时间之前间隔第三预设时长的时间。
在一些实施例中，预定义的第一时间线在一个时间窗中，时间窗的终止时间为调度单元的起始时间之前至少间隔第二预设时长的时间，时间窗的起始时间为时间窗的终止时间之前间隔第三预设时长的时间。
在一些实施例中，多个第一信道被执行复用的最早时间位置在时间窗中。
需说明的是，时间窗的内容可参考上述实施例中对时间窗的描述，本公开实施例在此不再赘述。
可以理解的是，本公开实施例提供的方法中，第一时间线是一个时间窗，可以限制复用操作的时间窗口，使得资源调度更加精准和快速，提高频谱资源的利用效率。此外，由于时间窗的终止时间可以被配置在第一时间线对应的时间位置之前的任意位置，因此可以基于通信系统的需求和实际的资源分配，对时间窗的终止时间进行配置，提高了系统的灵活性。
在一些实施例中，预定义的第一时间线在第二时间与第三时间之间，第二时间为多个第一信道中的最早起始符号之前至少间隔第一预设时长的时间，第三时间为第二时间之前间隔第三预设时长的时间。
在一些实施例中，预定义的第一时间线在第二时间与第三时间之间，第二时间为调度单元的起始时间之前至少间隔第二预设时长的时间，第三时间为第二时间之前间隔第三预设时长的时间。
在一些实施例中，多个第一信道被执行复用的最早时间位置在第二时间对应的时间位置和第三时间对应的时间位置之间。
在一些实施例中，如图14所示，上述确定多个第一信道基于信令指示被复用，可实现为：S401和S402。
在S401中，向第一节点发送第二信道。
在一些实施例中，第二信道包括下行控制信道，第二信道中的信令指示被承载在下行控制信道中的下行控制信息里。
在S402中，在第二信道里的信令指示被设置为开始执行复用的情况下，确定调度单元里截至当前的多个第一信道被执行复用。
需说明的是，上述S401和S402的内容，可参考上述S201和S202的描述，本公开实施例在此不再赘述。
可以理解的是，为了简化信道复用的规则，需要第一节点(例如，UE)和第二节点(例如，基站)对执行复用的时机的理解保持一致。本公开实施例提供的方法，通过基于信令指示确定对多个第一信道进行复用，可以防止多个第一信道开始执行复用之后，第二节点又调度新的信道，且该新的信道与原有的多个第一信道在时域重叠。从，而简化多个第一信道之间的复用规则，减少多个信道之间的复用歧义，降低复用的复杂性。
在一些实施例中，如图15所示，上述确定多个第一信道基于信令指示被复用，还包括：S403。
在S403中，在第二信道里的信令指示被设置为不开始执行复用的情况下，确定调度单元里截至当前的多个第一信道不被执行复用。
需说明的是，上述S403的内容，可参考上述S203的描述，本公开实施例在此不再赘述。
在一些实施例中，在相关技术中，一个传输的所有传输时机或重复(repetition)都是在相同的符号类型里，所以，这些传输时机或重复所面对的信道环境也是相同或接近的，因此一套传输参数就可以适用于所有传输时机或重复。但是，由于子带全双工(subband full duplex，SBFD)技术的引入，导致两种符号类型出现，即SBFD符号和非子带全双工(non-subband full duplex，non-SBFD)符号，在传输时，不同符号类型对应的干扰以及信道环境是不同的。
如果一个传输(可以是DL传输或UL传输，下述以UL传输为例进行说明)的不同重复或传输时机是在不同的slot里，且在对应的slot里仅能使用SBFD或non-SBFD符号。例如，一个传输是SRS、PUCCH或PUSCH，且该传输能被传输在不同slot里的SBFD符号和non-SBFD符号里。作为一个示例，周期性的探测参考信号(sounding reference signal，SRS)、PUCCH或PUSCH的不同的传输时机分别在不同的slot里，且在对应的slot里只能使用SBFD符号或者non-SBFD符号，例如周期为4个slot的传输，第一个传输时机在slot 1里且使用SBFD符号，第二个传输时机在slot 5里且使用non-SBFD符号。作为另一个示例，对于带有重复的SRS、PUCCH或PUSCH，不同的重复分别在不同的slot里，且在对应的slot里只能使用SBFD符号或non-SBFD符号。例如，带有4次重复的传输，第一次重复被执行在slot 1里且使用SBFD符号，第二次重复在slot 2里且使用non-SBFD符号，第三次传输时机在slot 3里且使用non-SBFD符号，第四次传输时机在slot 4里且使用non-SBFD符号。
由于信道环境的不同，所以该一个传输的不同重复或传输时机需要不同的传输参数。传输参数包括以下至少一项：空间参数、功率控制参数、传输配置指示符状态(transmission configuration indicator state，TCI-State)、传输配置指示符上行状态(transmission configuration indicator ul state，TCI-UL-State)、编码调制等级、频域资源、时域资源、控制相关参数。下述将给出方法来提供传输参数。进一步，针对一个带有重复的传输，下述也将基于提供的不同传输参数，提供不同重复的发送规则。
在一些实施例中，空间参数包括：UE发送/接收时的使用的波束相关信息和/或预编码信息。
在一些实施例中，功率控制参数包括：影响UE发送/接收的相关的参数。例如，与闭环功率控制相关的参数、与开环功率控制相关的参数、步进功率调整的参数。
在一些实施例中，TCI-State用于描述DL信号之间的准共址(quasi co-location，QCL)关系。
在一些实施例中，TCI-UL-State用于描述用于UL信号传输的TCI-State。
在一些实施例中，基站配置第一传输参数集合和第二传输参数集合，且配置第一传输参数集合和第二传输参数集合分别与SBFD符号关联，也配置第三传输参数集合和第四传输参数集合，且配置第三传输参数集合和第四传输参数集合分别与non-SBFD符号关联。
对于一个带有n次重复的传输，该n次重复传输分别在不同的slot里。该n次重复传输能被区分为两部分，即n＝n1+n2，n1的范围为0,1,2,3，...,n。n2的范围为0,1,2,3,...,n。n1表示该传输有n1次重复是在SBFD符号里，n2表示该传输有n2次重复是在non-SBFD符号里。
在一些实施例中，n1和n2的取值可以根据该传输n次重复所在的符号类型确定。也就是说，可以根据SBFD子带在时域的配置图样确定。
对于该一个传输的n次重复，与SBFD符号关联的n1次重复使用相同的频域资源1(或时域资源1)，与non-SBFD符号关联的n2次重复使用相同的频域资源2(或时域资源2)。频域资源1与频域资源2可以相同，也可以不同。
在一些实施例中，对于一个周期的传输，例如，半持续调度(Semi-Persistent Scheduling，SPS)PDSCH，或半静态PUSCH，不同的周期处的传输时机在不同的slot里。这些传输时机(记为n个传输时机)能被区分为两部分组成，即n＝n1+n2。n1表示n1个传输时机是在SBFD符号里，n2表示n2个传输时机是在non-SBFD符号里。
在一些实施例中，n1和n2的取值可以根据该传输的周期位置所在的符号类型确定。也就是说，可以根据SBFD子带在时域的配置图样确定。
对于n次的传输时机，与SBFD符号关联的n1次传输时机使用相同的时频资源1，与non-SBFD符号关联的n2次传输时机使用相同的时频资源2。时频资源1与时域资源2可以相同，也可以不同。
在一些实施例中，对于一个传输的n次重复(或n次传输时机)，应该满足以下规则1至规则3中的至少一项。
规则1
在(n1个slot里的)SBFD符号里n1次重复(或n1次传输时机)里的第一次重复(或第一次传输时机)使用第一传输参数集合，第二次重复(或第二次传输时机)使用第二传输参数集合，并且交替执行，直到n1次重复(或n1次传输时机)被执行。
在(n2个slot里的)non-SBFD符号里n2次重复(或n2次传输时机)里的第一次重复(或第一次传输时机)使用第三传输参数集合，第二次重复(或第二次传输时机)使用第四传输参数集合，并且交替执行，直到n2次重复(或n2次传输时机)被执行。
下面以n次重复为例进行说明，针对n次传输时机，只需要将下述的“重复”替换为“传输时机”即可。
在一些实施例中，图16为UL传输示意图。如图16所示，包括DL slot和UL slot，以及包括UL子带和DL子带，SBFD子带被配置在DL符号或者F符号(例如，UL符号)里。DL slot在图16中简称为“D”，UL slot在图16中简称为“U”。一个被配置重复4次的上行传输(四次重复分别记作rep1、rep2、rep3、rep4)，其第一次重复rep1被配置或指示在第4个slot里，然后结合SBFD子带图样以及后续slot的确定规则，UE确定后续的重复分别在第5、第6和第7个slot里。rep1和rep2的重复在non-SBFD符号里，对应于n2。rep3和rep4的重复在SBFD符号里，对应于n1。即，与SBFD符号对应的n1等于2，与non-SBFD符号对应的n2等于2。
根据规则1，对于n1对应的重复，交替应用第一传输参数集合和第二传输参数集合。例如，如图16所示，rep3使用第一传输参数集合，rep4使用第二传输参数集合。
根据规则1，对于n2对应的重复，交替应用第三传输参数集合和第四传输参数集合。例如，如图16所示，rep1使用第三传输参数集合，rep2使用第四传输参数集合。
需说明的是，SBFD子带被配置在DL符号或者F符号(例如，UL符号)里，被配置了SBFD子带的符号记为SBFD符号，未被配置SBFD子带的符号记为non-SBFD符号。如果一个UL传输在non-SBFD符号里，是指该UL传输被传输在未配置SBFD子带的UL符号或者F符号(例如，UL符号)里。如果一个DL传输被传输在non-SBFD符号里，是指该DL传输被传输在未配置SBFD子带的DL符号或者F符号(例如，UL符号)里，下述不再赘述。

根据规则1，对于n1对应的重复，交替应用第一传输参数集合和第二传输参数集合。例如，如图17所示，rep3使用第一传输参数集合，rep4使用第二传输参数集合。
根据规则1，对于n2对应的重复，交替应用第三传输参数集合和第四传输参数集合。例如，如图17所示，rep1使用第三传输参数集合，rep2使用第四传输参数集合。
在一些实施例中，图18为UL传输示意图。如图18所示，包括DL slot和UL slot，以及包括UL子带和DL子带，SBFD子带被配置在DL符号或者F符号(例如UL符号)里。DL slot在图18中简称为“D”，UL slot在图18中简称为“U”。一个被配置重复8次的上行传输(八次重复分别记作rep1、rep2、rep3、rep4、rep5、rep6、rep7、rep8)，其第一次重复rep1被配置或指示在第4个slot里，然后结合SBFD子带图样以及后续slot的确定规则，UE确定后续的重复分别在第5、第6、第7、第8、第9、第10和第11个slot里。rep1、rep2、rep6和rep7的重复在non-SBFD符号里，对应于n2。rep3、rep4、rep5和rep8的重复在SBFD符号里，对应于n1。即，与SBFD符号对应的n1等于4，与non-SBFD符号对应的n2等于4。
根据规则1，对于n1对应的重复，交替应用第一传输参数集合和第二传输参数集合。例如，如图18所示，rep3使用第一传输参数集合，rep4使用第二传输参数集合，rep5使用第一传输参数集合，rep8使用第二传输参数集合。
根据规则1，对于n2对应的重复，交替应用第三传输参数集合和第四传输参数集合。例如，如图18所示，rep1使用第三传输参数集合，rep2使用第四传输参数集合，rep6使用第三传输参数集合，rep7使用第四参数集合。
在一些实施例中，UE和基站约定：如果n1对应的重复只有一个，则该重复使用第一传输参数集合；如果n2对应的重复只有一个，则该重复使用第三传输参数集合。
在一些实施例中，图19为DL传输示意图。如图19所示，包括DL slot和UL slot，以及包括UL子带和DL子带，SBFD子带被配置在DL符号或者F符号(例如UL符号)里。DL slot在图19中简称为“D”，UL slot在图19中简称为“U”。一个被配置重复8次的下行传输(八次重复分别记作rep1、rep2、rep3、rep4、rep5、rep6、rep7、rep8)，其第一次重复rep1被配置或指示在第3个slot里，然后结合SBFD子带图样以及后续slot的确定规则，UE确定后续的重复分别在第4、第6、第7、第8、第9、第11和第12个slot里。rep1、rep2和rep6的重复在non-SBFD符号里，对应于n2。rep3、rep4、rep5、rep7和rep8的重复在SBFD符号里，对应于n1。即，与SBFD符号对应的n1等于5，与non-SBFD符号对应的n2等于3。
根据规则1，对于n1对应的重复，交替应用第一传输参数集合和第二传输参数集合。例如，如图19所示，rep3使用第一传输参数集合，rep4使用第二传输参数集合，rep5使用第一传输参数集合，rep7使用第二传输参数集合，rep8使用第一传输参数集合。
根据规则1，对于n2对应的重复，交替应用第三传输参数集合和第四传输参数集合。例如，如图19所示，rep1使用第三传输参数集合，rep2使用第四传输参数集合，rep6使用第三参数集合。
在一些实施例中，基站与UE约定：如果n1对应的重复只有一个，则该重复使用第一传输参数集合；如果n2对应的重复只有一个，则该重复使用第三传输参数集合。
规则2
在(n1个slot里的)SBFD符号里n1次重复(或n1次传输时机)里的连续m次重复(或m次传输时机)使用第一传输参数集合，之后连续m次重复(或m次传输时机)使用第二传输参数集合，并交替执行直到n1次重复(或n1次传输时机)被执行。
在(n2个slot里的)non-SBFD符号里n2次重复(或n2次传输时机)里的连续m次重复(或m次传输时机)使用第三传输参数集合，之后连续m次重复(或m次传输时机)使用第四传输参数集合，并交替执行直到n2次重复(或n2次传输时机)被执行。m可以被基站配置，或m可以在基站与UE之间预定义。m的范围可以预定义为{1,2}。
在一些实施例中，m与传输的重复次数有关联，例如，重复次数小于等于4时，m＝1；重复次数大于4时，m的取值1或2。
下面以m次重复为例进行说明，针对m次传输时机，只需要将下面的“重复”替换为“传输时机”即可。
在一些实施例中，图20为UL传输示意图。如图20所示，包括DL slot和UL slot，以及包括UL子带和DL子带，SBFD子带被配置在DL符号或者F符号(例如，UL符号)里。DL slot在图20中简称为“D”，UL slot在图20中简称为“U”。一个被配置重复8次的上行传输(八次重复分别记作rep1、rep2、rep3、rep4、rep5、rep6、rep7、rep8)，其第一次重复rep1被配置或指示在第4个slot里，然后结合SBFD子带图样以及后续slot的确定规则，UE确定后续的重复分别在第5、第6、第7、第8、第9、第10和第11个slot里。rep1、rep2、rep6和rep7的重复在non-SBFD符号里，对应于n2。rep3、rep4、rep5和rep8的重复在SBFD符号里，对应于n1。即，与SBFD符号对应的n1等于4，与non-SBFD符号对应的n2等于4。这里假设m被配置为2。
根据规则2，对于n1对应的重复，每连续m个重复交替应用第一传输参数集合和第二传输参数集合。例如，如图20所示，rep3和rep4使用第一传输参数集合，rep5和rep8使用第二传输参数集合。
根据规则2，对于n2对应的重复，每连续m个重复交替应用第三传输参数集合和第四传输参数集合。例如，如图20所示，rep1和rep2使用第三传输参数集合，rep6和rep7使用第四传输参数集合。
在一些实施例中，图21为DL传输示意图。如图21所示，包括DL slot和UL slot，以及包括UL子带和DL子带，SBFD子带被配置在DL符号或者F符号(例如，UL符号)里。DL slot在图21中简称为“D”，UL slot在图21中简称为“U”。一个被配置重复8次的下行传输(八次重复分别记作rep1、rep2、rep3、rep4、rep5、rep6、rep7、rep8)，其第一次重复rep1被配置或指示在第3个slot里，然后结合SBFD子带图样以及后续slot的确定规则，UE确定后续的重复分别在第4、第6、第7、第8、第9、第11和第12个slot里。rep1、rep2和rep6的重复在non-SBFD符号里，对应于n2。rep3、rep4、rep5、rep7和rep8的重复在SBFD符号里，对应于n1。即，与SBFD符号对应的n1等于5，与non-SBFD符号对应的n2等于3。这里假设m被配置为2。

在一些实施例中，基站与UE约定：如果n1对应的重复只有一个，则该重复使用第一传输参数集合；如果n2对应的重复只有一个，则该重复使用第三传输参数集合。
规则3
如果UE具有多个面板，例如，面板1和面板2，则上述的规则1和规则2能被改进。每个面板可以独立用于发送或接收。
改进包括对于规则1的改进。对于n1次的重复(或传输时机)在SBFD符号里，第一次重复(或第一次传输时机)同时使用第一传输参数集合和第二传输参数集合(分别基于面板1和面板2)，第二次重复(或第二次传输时机)同时使用第一传输参数集合和第二传输参数集合(分别基于面板1和面板2)，直到n1次重复(或n1次传输时机)被执行。在n2次重复(或n2次传输时机)在non-SBFD符号里，第一次重复(或第一次传输时机)同时使用第三传输参数集合和第四传输参数集合(分别基于面板1和面板2)，第二次重复(或第二次传输时机)同时使用第三传输参数集合和第四传输参数集合(分别基于面板1和面板2)，直到n2次重复(或n2次传输时机)被执行。如果UE具有面板1和面板2，则可以通过面板1和面板2分别执行发送。如果基站具有面板1和面板2，则可以通过面板1和面板2分别执行发送。
相关技术中，SBFD子带被引入，参考3GPP中的内容，本公开实施例基于DL符号里配置的SBFD子带，提供一种宽带(wideband)资源块组(precoding resource block Group，PRG)的确定方法。在被配置SBFD子带的DL符号(记为SBFD符号)里，由于部分频域资源(记为UL子带)被用于UL传输，剩余的频域资源(记为DL子带)用于DL传输，而在相关技术里一个DL符号的所有频域资源被用于DL传输。所以，相关技术的定义宽带PRG的确定方法不适用于SBFD符号里的宽带PRG确定。
在一些实施例中，在SBFD子带配置中，会有多种配置图样，包括“DU”、“UD”或“DUD”等。D表示下行子带，U表示上行子带。
作为一个示例，图22为SBFD子带配置的示意图。如图22所示，SBFD子带被配置在DL子带和UL子带中，SBFD子带的配置图样“DU”。DL子带和UL子带之间有一条防护子带(guard band)。
作为另一个示例，图23为SBFD子带配置的示意图。如图23所示，SBFD子带依次被配置在DL子带、UL子带和DL子带中，SBFD子带的配置图样“DUD”。DL子带与UL子带之间有一条防护子带。
在一些实施例中，基站与UE约定，如果一个PDSCH的物理资源块(physical resource block，PRB)被调度在SBFD符号里，则采用下面的方式来确定采用wideband PRG或不采用wideband PRG为该PDSCH。示例性地，改进包括下面至少之一：针对BWP(Bandwidth Part，部分带宽)size(记为)的改进、针对被调度的PRBs(记为scheduled PRBs)的改进、针对判断条件的改进。上述3个方面的改进能够组合使用来确定PRG的size或确定wideband PRG。
在一些实施例中，针对BWP size(记为)的改进包括以下至少一项：针对“DU”或“UD”的SBFD图样。BWP的size(size以PRB描述size)改进可以包含以下至少一项：BWP的size为UE的DL BWP的size，虽然PDSCH被传输在DL子带，但是仍然使用DL BWP的size确定PRG的size；BWP的size改为DL BWP里除去UL子带和频域间隔(gap)(如有)之外剩余的带宽对应的size；BWP的size改为DL子带的size，示例性地，DL子带包括可用PRB和不可用PRB，可用PRB是DL BWP域DL子带在频域交集得到的PRBs，或者可用PRB是被配置为从DL子带里除了可用PRB外，剩余的PRB是不可用PRB；BWP的size改为DL子带里可用PRB对应的size，例如，仅包括可用PRB。可用PRB已被预先定义。
针对“DUD”的SBFD图样，BWP的size包括以下至少一项：BWP的size为UE的DL BWP的size，虽然PDSCH被传输在DL子带，但是仍然使用DL BWP的size确定PRG的size；BWP的size改为DL BWP里除去UL子带和频域gap(如有)之外剩余的带宽对应的size；BWP的size改为DL子带1和DL子带2的size之和(即DL子带的size)，例如，这里的DL子带包括可用PRB和不可用PRB，例如，被调度的PRBs分别在DL子带1和DL子带2里，且在每个DL子带里是连续的；BWP的size改为DL子带1和DL子带2的可用PRB之和对应的size，例如，DL子带1和DL子带2里的可用PRB之和对应的size，例如，被调度的PRBs分别在DL子带1的可用PRB里和DL子带2的可用PRB里，且在每个DL子带里是连续的；BWP的size改为DL子带1的size，例如，这里的DL子带1包括可用PRB和不可用PRB，例如，被调度的PRBs连续且仅在DL子带1里，则BWP的size改为DL子带1的size；BWP的size改为DL子带1里的可用PRB的size，例如，被调度的PRBs连续且仅在DL子带1里，则BWP的size改为DL子带1里的可用PRB的size；BWP的size改为DL子带2的size，例如，这里的DL子带2包括可用PRB和不可用PRB，例如，被调度的PRBs连续且仅在DL子带2里，则BWP的size改为DL子带2的size；BWP的size改为DL子带2里的可用PRB的size，例如，被调度的PRBs连续且仅在DL子带2里，则BWP的size改为DL子带2里的可用PRB的size。
针对被调度的PRB(即the scheduled PRBs)的改进(不区分SBFD图样)包括以下至少一项：被调度的PRB为DCI里的频域资源分配域为UE分配的资源，它能包括可用PRB、不可用PRB以及落入UL子带和频域gap里的PRB。例如，被分配的PRBs中的一些PRBs落入UL子带里，这些PRBs也算作被调度PRB在确定被调度的PRB的size时。
被调度的PRB为DCI里的频域资源分配域为UE分配的资源，但从为UE分配的资源中除去不可用PRB和落入UL子带和频域gap里的PRB，或者说，被调度的PRB是DCI里的频域资源分配域为UE分配的资源中仅在可用PRB里的PRB。例如，被分配的PRBs中的一些PRBs落入UL子带里，则这些PRBs不算作被调度PRB在确定被调度的PRB的size时。例如，被分配的PRBs中仅仅落入DL子带里的PRB被算作被调度的PRB在确定被调度的PRB的size时。
被调度的PRB为DCI里的频域资源分配域为UE分配的资源，它能包括可用PRB、不可用PRB，但不包括落入UL子带和频域gap里的PRB。例如，只要被分配的资源落入DL子带里，则该资源就算作被调度的PRB(不管是否是可用PRB)在确定被调度的PRB的size时。
被调度的PRB与用于确定该PDSCH的TBS(Transmission Block Size)(TBS表示传输块(Transmission Block，TB)的大小)的PRB数量相同。作为一个示例，基于DCI里的频域资源分配域为UE分配的资源，该资源被用于传输该UE的一个TB，UE确定该TB的size基于被分配的资源。该资源包括可用PRB、不可用PRB以及落入UL子带和频域gap里的PRB。同时，该资源被用于确定PRG的size。作为另一个示例，基于DCI里的频域资源分配域为UE分配的资源，该资源被用于传输该UE的一个TB，UE确定该TB的size基于被分配的资源中仅仅位于DL子带里的可用PRB。同时，UE确定该PRG的size基于被分配的资源中仅仅位于DL子带里的可用PRB。作为又一个示例，基于DCI里的频域资源分配域为UE分配的资源，该资源被用于传输该UE的一个TB。UE确定该TB的size基于被分配的资源，该资源包括可用PRB和不可用PRB但不包括落入UL子带和频域gap里的PRB。同时，该资源被用于确定PRG的size。
在一些实施例中，如果为“DU”或“UD”图样，上述的用于被调度的PRBs是连续的。
在一些实施例中，如果为“DUD”的SBFD图样，上述的用于被调度的PRBs是连续的在每个DL子带里。
在一些实施例中，针对判断条件的改进(不区分SBFD)包括以下至少一项：在相关的wideband PRG确定时，采用的判断条件是被调度的PRB数量大于DL BWP的PRB数量的一半，则确定为wideband PRG，或者则确定PRG的size是wideband。改进的判断条件包括以下至少一项：被调度的PRB数量大于BWP的PRB数量的一半。
对于被调度的PRB仅在一个DL子带里，如果被调度的PRB数量大于DL子带的PRB数量的一半，则确定为wideband PRG。DL子带是该被调度的PRB所在的DL子带，或者是两个DL子带的PRB之和。
对于被调度的PRB仅在一个DL子带里，如果被调度的PRB数量大于DL可用PRB数量的一半，则确定为wideband PRG。DL可用PRB是该被调度的PRB所在的DL子带里的DL可用PRB，或者是两个DL子带的DL可用PRB之和。
对于被调度的PRB同时在2个DL子带里，如果被调度的PRB数量大于DL子带的PRB数量的一半，则确定为wideband PRG。DL子带是两个DL子带的PRB数量之和。
对于被调度的PRB同时在2个DL子带里，如果被调度的PRB数量大于DL可用PRB数量的一半，则确定为wideband PRG。DL可用PRB是两个DL子带的可用PRB数量之和。
对于被调度的PRB同时在2个DL子带里，则在DL子带1里，被调度的PRB中落入DL子带1里的PRB的数量大于DL子带1里PRB数量的一半(或大于DL子带1里可用PRB数量的一半)，则在DL子带1里，确定为wideband PRG；在DL子带2里，被调度的PRB中落入DL子带2里的PRB的数量大于DL子带2里PRB数量的一半(或大于DL子带2里可用PRB数量的一半)，则在DL子带2里，确定为wideband PRG；DL子带1和DL子带2单独确定是否满足widwband PRG，且DL子带1和DL子带2可以使用相同或不同的预编码。
在一些实施例中，改进的判断条件还可以包括以下至少一项：基站与UE约定，根据被调度的PRB的分布情况，例如，被调度的PRB仅在一个DL子带里，或者被调度的PRB同时在两个DL子带里，来判断是wideband PRG。该改进的判断条件包括下述至少之一：对于被调度的PRB，如果同时在2个DL子带里，则基于两个DL子带里的PRB数量来确定wideband PRG；对于被调度的PRB，如果仅在1个DL子带里，则基于该DL子带里的PRB数量来确定wideband PRG；对于被调度的PRB，如果同时在2个DL子带里，则基于两个DL子带里的可用PRB数量来确定wideband PRG；对于被调度的PRB，如果仅在1个DL子带里，则基于该DL子带里的可用PRB数量来确定wideband PRG；对于被调度的PRB，如果同时在2个DL子带里，则基于DL BWP的PRB数量来确定wideband PRG；对于SBFD图样是“DU”，则基于DL BWP的PRB数量来确定wideband PRG；对于SBFD图样是“DU”，则基于该DL子带里的PRB数量来确定wideband PRG；对于SBFD图样是“DU”，则基于该DL子带里的可用PRB数量来确定wideband PRG；对于SBFD图样是“DUD”，则基于该两个DL子带里的PRB数量之和来确定wideband PRG；对于SBFD图样是“DUD”，则基于该两个DL子带里的可用PRB数量来确定wideband PRG；对于SBFD图样是“DUD”，则基于DL BWP PRB数量来确定wideband PRG。

基于本公开实施例提供的信道复用方法，在多个第一信道将在一个调度单元里被接收的情况下，第二节点确定多个第一信道基于预定义的第一时间线或者基于信令指示被复用，可以有效地协调不同类型的信道复用，减少不同信道复用规则之间的冲突和歧义，避免因规则不协调导致的通信中断或错误，进而保障信息传输的稳定性。并且，确定多个第一信道基于预定义的第一时间线或者基于信令指示被复用，可以简化第二节点对信道复用规则的管理，使得第二节点更容易理解复用规则。
此外，预定义的第一时间线或信令指示为信道复用提供了更多的灵活性，可以基于实际的通信需求调整第一时间线或者信令指示，进而合理地分配通信资源，提高资源的利用率。
