- downlink time slots and/or downlink symbols often account for more resources, such as the slot structure similar to DDDSU, which will bring the following problems:
- the spectrum utilization efficiency is low.

- the terminal 1 receives downlink control information on a certain time domain resource, and terminal 2 simultaneously transmits PUSCH/PUCCH/SRS on the certain time domain resource, then the terminal 1 The received downlink control information will be interfered by the PUSCH/PUCCH/SRS sent by the terminal 2, which will result in failure to receive the downlink control information and reduce system performance.
- FIG. 7 is another example of a resource format based on full-duplex communication provided by the embodiment of the present application.
- the sending position of SSB and/or CSI-RS usually does not change due to the backward compatibility of the system.
- PUSCH supports The allocation of discrete resources will increase the signaling overhead of DCI, so PUSCH only supports the allocation of continuous resources.
- the resources where the SSB is located and/or the resources where the CSI-RS is located may be different from the time when the network device allocates PUSCH.
- the frequency resources collide, which in turn causes the PUSCH to interfere with the downlink reception of the SSB and/or CSI-RS, degrading the system performance.
- the proportion of downlink services is generally greater than that of uplink services, that is to say, the resources occupied by downlink services are generally more than those occupied by uplink services.

- the terminal device may also determine whether to send or receive the first physical channel based on the first information or the first resource, for example, if the first resource and the first physical channel do not overlapping, the terminal device can send or receive the first physical channel on the resource where the first physical channel is located, and correspondingly, the network device can receive or send the first physical channel on the resource where the first physical channel is located For another example, if the first resource overlaps with the first physical channel, the terminal device may not send (that is, cancel sending) or not receive (that is, cancel receiving) the first physical channel. correspondingly, the network device also cancels receiving or sending the first physical channel.

- the terminal device usually, for the first physical channel, the terminal device only needs to determine the resource where the first physical channel is located, and the terminal device does not care about not being used to send or receive the first physical channel.
- this application newly introduces the concept of the first information to solve the interference problem of the signal received on the first resource.

因此,本领域亟需一种能够降低接收干扰的无线通信方法,以提升系统性能。

为了便于理解本申请提供的方案,下面对灵活时分双工(Time Division Duplexing,TDD)的相关内容进行说明。
灵活TDD可以采用灵活的时隙结构,即在一个时隙中可以包括下行(DL)符号、灵活(Flexible)符号和上行(UL)符号,其中灵活符号的符号方向是未定的,可以通过其他信令将其改变成下行符号或上行符号。此外,NR定义了多种灵活时隙结构,包括全下行时隙、全上行时隙、全灵活时隙,以及不同下行符号、上行符号、灵活符号个数的时隙结构。
网络设备可通过半静态上下行配置和/或动态上下行配置为终端配置灵活的时隙结构。
具体地,半静态上下行配置包括时分双工上下行公共配置(tdd-UL-DL-ConfigurationCommon)和时分双工上下行专用配置(tdd-UL-DL-ConfigurationDedicated),时分双工上下行公共配置是小区级别的时隙结构配置,时分双工上下行专用配置是用户专用(UE specific)的时隙结构的配置。
其中,时分双工上下行公共配置或时分双工上下行专用配置的配置参数包括但不限于:参考子载波间隔μ
ref、周期P、下行时隙数d
slots、下行符号数d
sym、上行时隙数u
slots、上行符号数u
sym。由于参考 子载波间隔μ
ref可用于确定时隙的长度,因此可根据参考子载波间隔μ
ref和周期P确定周期P内包括的时隙个数总数S,该S个时隙中的前d
slots个时隙表示全下行时隙,最后一个全下行时隙的下一个时隙中的前d
sym个符号表示下行符号;该S个时隙中的最后u
slots个时隙表示全上行时隙,第一个全上行时隙的前一个时隙中的最后u
sym个符号表示上行符号;该周期P中的其余的符号表示灵活符号。
图2是本申请实施例提供的基于灵活TDD的时隙格式的示意图。
如图2所示,若μ
ref=15KHz,P=5ms,则终端设备可根据μ
ref和周期P确定该周期P内包括的时隙个数总数为4,d
slots=1,d
sym=2,u
slots=1,u
sym=6。当然,图2所示的数值仅为本申请的示例,不应理解为对本申请的限制。
此外,动态上下行配置包括时隙格式指示(Slot Format Indicator,SFI),SFI可以动态指示每个时隙的时隙格式。SFI只能配置通过半静态上下行配置所配置的灵活符号的方向,例如图2所示的灵活符号,不能改变半静态配置信息配置为上行符号和下行符号的方向,例如,图2所示的上行符号和下行符号。
灵活TDD的好处在于可以动态适配网络的上下行业务,降低时延,具有良好的前向兼容性。
然而,虽然灵活TDD的灵活时隙和/或灵活符号的方向可以被灵活配置为上行方向或下行方向,但是如果一个灵活符号被指示为下行符号,此时,网络设备和终端设备采用半双工的工作方式时,终端设备在下行符号上只能执行接收操作,网络设备在下行符号上只能执行发送操作;如果一个灵活符号被指示为上行符号,此时,网络设备和终端设备采用半双工的工作方式时,终端设备在上行符号上只能执行发送操作,也即是说,网络设备在上行符号或下行符号上不能同时进行收发操作。
此外,由于系统中的业务的非对称性,下行业务的比例一般大于上行业务,因此在灵活TDD的上下行配置或指示的时隙结构中,下行时隙和/或下行符号经常会占比较多的资源,如与DDDSU类似的时隙结构,这会带来以下问题:
1、由于上行资源较少,导致的上行覆盖受限。
2、由于上行资源较少,需要等到有上行时隙和/或符号时才能发送下行数据的反馈信息或上行数据,进而导致的上行反馈和/或上行调度的时延增大。例如,如图3所示,当有下行数据的上行HARQ-ACK需要反馈时,用于传输下行数据的下行符号和用于反馈上行HARQ-ACK的上行符号之间的反馈延迟过大;当有上行数据需要调度时,上行数据到达所在的符号和用于传输上行数据的上行符号之间的对准时延过大。
3、由于上下行时间的分割,导致的频谱利用效率较低。例如,对于一个下行符号的所有频域资源,即使下行数据没有占满该符号对应的所有频域资源,剩余的频域资源也无法用于传输上行数据或下行数据的反馈信息。
本申请可以通过全双工通信方式克服上述问题,全双工通信的核心概念为在同一时间上同时进行收发操作。全双工通信方式可包括基站全双工+终端半双工的通信方式、基站全双工+终端全双工的通信方式等不同的工作方式,下面结合附图对全双工通信的相关内容进行说明。
图4至图6是本申请实施例提供的基于全双工通信的资源格式的示例。
如图4所示,假设一个方块所在的时域资源代表1个时隙,则基于全双工通信的资源格式包括4个时隙,从左到右的第2个时隙同时包括上行资源和下行资源,也即是说,网络设备和终端设备可以在所述第2个时隙上同时进行收发操作。如图5所示,假设一个方块所在的时域资源代表1个时隙,则基于全双工通信的资源格式包括5个时隙,从左到右的前4个时隙同时包括上行资源和下行资源,也即是说,网络设备和终端设备可以在所述前4个时隙上同时进行收发操作。如图6所示,基于全双工通信的资源格式包括上行资源和下行资源,网络设备和终端设备可以在上行资源和下行资源重叠的时域资源上同时进行收发操作。
在实际通信过程中,终端设备需要接收很多下行参考信号和/或下行物理信道,以辅助终端设备进行同步、控制信息的接收以及信道测量等过程,例如,同步信号和/或物理广播信道块(Synchronization Signal/PBCH Block,SSB)、控制资源集(Control Resource Set,CORESET)上承载的信道、信道状态信息参考信号(Channel State Information Reference Signal,CSI-RS)、小区参考信号(Cell Reference Signal,CRS)。
此外,终端设备也需要发送很多上行参考信号或上行物理信道等,以辅助网络设备实现对终端设备的调度等操作,例如,探测参考信号(Sounding Reference Signal,SRS)、承载有调度请求(Scheduling Request,SR)、混合自动重传请求确认(Hybrid Automatic Repeat Request-ACK,HARQ-ACK)、信道状态信息(Channel State Information,CSI)的物理上行控制信道(Physical Uplink Control Channel,PUCCH)。
上述类型的信号和/或信道在系统中扮演着非常重要的角色,通常情况下,这种类型的信号和/或信 道是通过高层信令或者协议预定义的周期进行传输的。
然而,通过下行控制信息(Downlink Control Information,DCI)进行数据的上行授权调度或下行授权调度时,通常情况下,只会对整块时频资源进行分配,以节省DCI的开销,此时,当基站或终端全双工通信时,如果DCI分配的资源上同时接收上述类型的信号和/或信道,发送的数据会对这种类型的信号或信息的接收产生干扰,降低了系统性能。
例如,以用于下行测量或下行同步的参考信号为例,若终端1在某一时域资源上接收用于下行测量或下行同步的参考信号时,终端2在所述某一时域资源上同时发送PUSCH/PUCCH/SRS,则所述终端1收到的参考信号会受到来自所述终端2发送的PUSCH/PUCCH/SRS的干扰,进而导致下行测量不准确或下行同步失败,降低了系统性能。再如,以下行控制信息为例,若终端1在某一时域资源上接收用于下行控制信息时,终端2在所述某一时域资源上同时发送PUSCH/PUCCH/SRS,则所述终端1收到的下行控制信息会受到来自所述终端2发送的PUSCH/PUCCH/SRS的干扰,进而导致下行控制信息接收失败,降低了系统性能。
图7是本申请实施例提供的基于全双工通信的资源格式的另一示例。
如图7所示,假设网络设备采用全双工通信的资源格式,由于要保证系统的后向兼容性,因此SSB和/或CSI-RS的发送位置通常不会发生改变,此外,由于PUSCH支持离散资源的分配时,会增加DCI的信令开销,因此PUSCH仅支持连续资源的分配,基于此,SSB所在的资源和/或CSI-RS所在的资源有可能会和网络设备为PUSCH分配的时频资源发生冲突,进而导致PUSCH对SSB和/或CSI-RS的下行接收产生干扰,降低了系统性能。例如,结合图7来说,当对前4个时隙进行资源分配时,SSB所在的资源和CSI-RS所在的资源均和网络设备为PUSCH分配的时频资源发生了冲突,导致PUSCH对SSB和/或CSI-RS的下行接收产生干扰,降低了系统性能。
与此同时,由于系统中的业务的非对称性,下行业务的比例一般大于上行业务,也即是说,下行业务占据的资源一般比上行业务占据的资源多,此时,很有可能会导致下行业务所在的资源和要发送的PUCCH(如SR HARQ-ACK或者CSI report)发生冲突,进而降低了系统性能。结合图7来说,当第1个时隙的上行资源上有配置的PUCCH(如SR HARQ-ACK或者CSI report)需要发送时,若图7所示的PDSCH为大包业务时,PDSCH需要占据整个带宽,甚至整个第一个时隙的资源,此时,很有可能会导致PDSCH所在的资源和要发送的PUCCH(如SR HARQ-ACK或者CSI report)发生冲突,降低了系统性能。
基于此,本申请实施例提供了一种无线通信方法、终端设备和网络设备,能够降低发送的物理信道对特定资源上接收的信号或信息产生干扰,进而能够提升系统性能。
图8示出了根据本申请实施例的无线通信方法200的示意性流程图,所述方法200可以由终端设备和网络设备交互执行。图8中所示的终端设备可以是如图1所示的终端设备,图8中所示的网络设备可以是如图1所示的接入网设备。
如图8所示,所述方法200可包括以下部分或全部内容:
S210,终端设备接收网络设备发送的第一信息,所述第一信息用于配置或指示第一资源,所述第一资源不用于发送或接收第一物理信道。
换言之,网络设备向终端设备发送所述第一信息,以向终端设备配置或指示第一资源。相应的,终端设备收到所述第一信息后,可基于所述第一信息配置或指示的第一资源发送或接收所述第一资源上的信号或信道,并基于所述第一信息配置或指示的第一资源确定是否发送或是否接收第一物理信道。
换言之,所述第一资源用于辅助所述第一物理信道的发送或接收。
具体来说,终端设备还可以基于所述第一信息或所述第一资源,发送或接收所述第一物理信道。例如,所述终端设备可基于所述第一信息或所述第一资源,采用资源映射的方式发送所述第一物理信道,即所述终端设备将所述第一物理信道映射在所述第一物理信道所在的除所述第一资源之外的资源上,所述第一物理信道所在的资源可以是网络设备通过RRC信令配置或者物理层控制信息指示的。当然,所述终端设备也可基于所述第一信息或所述第一资源,确定是否发送或是否接收所述第一物理信道,例如,若所述第一资源和所述第一物理信道不重叠,则所述终端设备可以在所述第一物理信道所在的资源上发送或接收所述第一物理信道,相应的,网络设备可以在所述第一物理信道所在的资源上接收或发送所述第一物理信道,再如,若所述第一资源和所述第一物理信道重叠,则所述终端设备可以不发送(即取消发送)或不接收(即取消接收)所述第一物理信道,相应的,网络设备也取消对所述第一物理信道的接收或发送。
本实施例中,通过引入第一信息,并将所述第一信息设计为用于配置或指示不用于发送或接收第一物理信道的第一资源,有利于终端设备避开所述第一资源发送或接收所述第一物理信道,甚至有利于终端确定是否取消所述第一物理信道的发送或接收,进而,能够降低所述第一物理信道对在第一资源上接 收的信号或信道产生干扰,提升了系统性能。例如,所述终端设备发送所述第一物理信道时,可以降低所述第一物理信道对所述终端设备在所述第一资源上接收的信号或信道产生的干扰,再如,所述终端设备接收所述第一物理信道时,可以降低所述第一物理信道对所述网络设备在所述第一资源上接收的信号或信道产生干扰,也即是说,本申请实施例提供的无线通信方法,能够降低发送的物理信道对特定资源上接收的信号或信息产生干扰,进而能够提升系统性能。
需要说明的是,通常情况下,针对第一物理信道,终端设备仅需要确定出所述第一物理信道所在的资源即可,所述终端设备并不关心不用于发送或接收所述第一物理信道的资源,本申请通过新引入所述第一信息的概念以解决在所述第一资源上接收的信号的干扰问题。
此外,由于所述第一物理信道支持离散资源的分配时,会增加DCI的信令开销,而所述第一物理信道仅支持连续资源的分配,会导致所述第一物理信道会和不用于发送或接收所述第一物理信道(即数据)的资源发生重叠;本申请中,即使所述第一物理信道仅支持连续资源的分配,在终端设备明确不用于发送或接收所述第一物理信道的第一资源后,有利于终端设备避开所述第一资源发送或接收所述第一物理信道,甚至有利于终端确定是否取消所述第一物理信道的发送或接收,进而,能够降低甚至避免所述第一物理信道对在第一资源上接收的信号或信道产生干扰,提升了系统性能。
需要说明的是,本申请实施例涉及的所述第一资源旨在说明不可用于(或不能被用于)发送或接收所述第一物理信道,也即是说,不可用于发送所述第一物理信道的资源都可以是所述第一资源,此外,本申请对所述第一资源的类型和资源位置不作限定。
例如,网络设备为所述第一物理信道分配的资源可以包括所述第一资源,也可以不包括所述第一资源。或者说,网络设备为所述第一物理信道分配的资源和所述第一资源可以完全重叠或部分重叠,也可以不重叠。示例性地,若网络设备为所述第一物理信道分配的资源包括所述第一资源,或所述网络设备为所述第一物理信道分配的资源与所述第一资源完全重叠或部分,则说明所述第一资源上接收的信号或信道会收到所述第一物理信道的干扰,此时,所述第一资源不用于发送或接收第一物理信道。当然,若网络设备为所述第一物理信道分配的资源不包括所述第一资源,或所述网络设备为所述第一物理信道分配的资源与所述第一资源不重叠,则网络设备为所述第一物理资源分配的资源上可以接收或发送所述第一物理信道,所述第一资源上也可以发送所述第一资源上的信号,即所述第一物理信道的传输和所述第一资源上的信号或信道的传输互不影响。
再如,所述第一资源可包括不用于发送PUSCH的资源和/或不用于接收PDSCH的资源。
再如,所述第一资源为上行资源或下行资源,所述第一资源为下行资源可以理解为:所述第一资源用于网络设备的下行发送或所述第一资源不可用于终端设备的上行发送,所述第一资源为上行资源可以理解为:所述第一资源用于网络设备的上行接收或所述第一资源不可用于终端设备的下行接收。
需要说明的是,所述第一资源可以是针对某一子频带的上行资源或下行资源。
图9是本申请实施例提供的不用于发送或接收第一物理信道的第一资源的示例。
如图9所示,假设网络设备基于全双工的通信方式,终端设备基于半双工的通信方式,从系统的角度来说,时隙1~4的子频带(subband)1和子频带3为下行资源,时隙1~4的子频带2为上行资源,由于终端设备时基于半双工的通信方式,因此终端设备在同一时刻只能执行接收操作或发送操作,也即是说,从终端设备的角度来看,时隙1~4是上行资源或者时隙1~4是下行资源。例如有可能终端1看到的是上行资源,例如终端1被调度在子频带2发送PUSCH和/或PUCCH,而终端2看到的是下行资源,例如终端2在子频带1和/或子频带3调度接收PDSCH等下行信息,但是不管终端1还是终端2,是不能在子频带1和/或子频带3上执行发送操作,也不能在子频带2上执行接收操作。
结合所述第一资源来说,若所述第一资源为下行资源,则所述第一资源为时隙1~4的子频带(subband)1和子频带3上的资源,若所述第一资源为上行资源,则所述第一资源为时隙1~4的子频带2上的资源。
应当理解,在其他可替代实施例中,本申请涉及的子频带也可替换为频段或频点等,本申请对此不作具体限定。
还需要说明的是,本申请涉及的术语“指示”可以是直接指示,也可以是间接指示,还可以是表示具有关联关系。举例说明,A指示B,可以表示A直接指示B,例如B可以通过A获取;也可以表示A间接指示B,例如A指示C,B可以通过C获取;还可以表示A和B之间具有关联关系。结合本申请来说,A表示所述第一信息,B表示所述第一资源。此外,术语“指示”可以实现为通过物理层的控制信息指示。类似的,本申请涉及的术语“配置”可以实现为通过高层信令配置,所述高层信令包括但不限于SIB、RRC以及MAC等。
在一些实施例中,所述第一资源不用于发送或接收第一物理信道包括:所述终端设备不期望所述第一物理信道和所述第一资源重叠,或者,在所述第一物理信道和所述第一资源重叠的情况下,所述终端 设备不期望发送或接收所述第一物理信道。
需要说明的是,本申请中,所述第一物理信道和所述第一资源重叠可以理解为:所述第一物理信道所在的资源和所述第一资源部分重叠或完全重叠,或网络设备为所述第一物理信道分配的资源和所述第一资源部分重叠或完全重叠。所述终端设备不期望(UE does not expect)发送或接收所述第一物理信道也可以理解为:所述终端设备不被要求(UE is not required)发送或接收所述第一物理信道。若所述终端设备不期望发送所述第一物理信道,相应的,网络设备可以尝试或不尝试接收所述第一物理信道;若所述终端设备不期望发送所述第一物理信道,相应的,网络设备也可以尝试或不尝试发送所述第一物理信道。所述终端设备不期望发送或接收所述第一物理信道,可包括:所述终端设备不期望在所述第一物理信道所在的资源上发送或接收所述第一物理信道,或所述终端设备不期望在所述第一资源上发送或接收所述第一物理信道。
在一些实施例中,所述第一物理信道为物理上行共享信道PUSCH。
可选的,所述第一资源包括以下中的至少一项:
SSB所在的资源、CORESET、CSI-RS所在的资源、CRS所在的资源。
本实施例中,将所述第一资源设计为包括SSB所在的资源、CORESET、CSI-RS所在的资源、CRS所在的资源中的至少一项,相对终端设备来说,可以降低所述第一物理信道对SSB、CORESET上承载的信道、CSI-RS或CRS的接收干扰,具体地,降低对SSB的接收干扰可以提高下行同步性能,降低对CORESET上承载的信道的接收干扰可以提高PDCCH的可靠性,降低对CSI-RS的干扰可以提高CSI报告的准确度,降低对对CRS的干扰,可以有效保证NR和LTE共存;与此同时,对网络设备来说,还可以降低所述SSB、CORESET上承载的信道、CSI-RS或CRS对所述第一物理信道的接收干扰。
在一些实施例中,所述第一物理信道为PDSCH。
可选的,所述第一资源包括以下中的至少一项:

本实施例中,将所述第一资源设计为包括第一PUCCH所在的资源、SRS资源中的至少一项,相对网络设备来说,可以降低所述第一物理信道对所述第一PUCCH或SRS的接收干扰;与此同时,相对终端设备来说,可以降低所述第一PUCCH或SRS对所述第一物理信道的接收干扰。
可选的,所述第一PUCCH所在的资源包括以下中的至少一项:
调度请求SR所在的资源、混合自动重传请求确认HARQ-ACK所在的资源、信道状态信息CSI所在的资源。
在一些实施例中,所述第一资源不用于发送或接收第一物理信道包括:所述第一资源不用于发送或接收所述第一物理信道由协议预定义。
换言之,可以通过协议预定义的方式约定所述第一信息指示或配置的第一资源不用于发送或接收所述第一物理信道。
示例性地,可以通过协议预定义的方式约定所述第一信息指示或配置的至少一个第一信号所在的资源不用于发送或接收所述第一物理信道。再如,可以通过协议预定义的方式约定所述第一信息指示或配置的至少一个第一信道所在的资源不用于发送或接收所述第一物理信道。也即是说,只要终端设备确定出所述至少一个第一信号所在的资源和/或所述至少一个第一信道所在的资源,所述终端设备可以将所述至少一个第一信号所在的资源和/或所述至少一个第一信道所在的资源直接确定为不用于发送或接收所述第一物理信道的第一资源。可选的,若所述第一物理信道为PUSCH,所述至少一个第一信号包括以下中的至少一项:CSI-RS、CRS;和/或,所述至少一个第一信道包括以下中的至少一项:SSB、CORESET上承载的信道。可选的,若所述第一物理信道为PDSCH,则所述至少一个第一信号包括SRS;和/或,所述至少一个第一信道包括第二PUCCH。可选的,所述第二PUCCH上承载的信息包括以下中的至少一项:SR、HARQ-ACK、CSI。
需要说明的是,在本申请实施例中,所述"协议预定义"可以通过在设备(例如,包括终端设备和网络设备)中预先保存相应的代码、表格或其他可用于指示相关信息的方式来实现,本申请对于其具体的实现方式不做限定。比如协议预定义的可以是通信领域的标准协议预定义的,本申请对标准协议的类型不作具体限定。例如可以包括LTE协议、NR协议以及应用于未来的通信系统中的相关协议,本申请对此不做具体限定。
在一些实施例中,所述第一资源包括至少一个第一速率匹配图样指示的资源。
示例性地,若所述第一速率匹配图样中第一比特位的取值为第一取值,则所述第一比特位对应的资源属于所述第一速率匹配图样指示的资源,即所述第一比特位对应的资源属于所述第一资源;若所述第一比特位的取值为第二取值,则所述第一比特位对应的资源不属于所述第一速率匹配图样指示的资源,即所述第一比特位对应的资源不属于所述第一资源。可选的,所述第一取值为0且所述第二取值为1。 可选的,所述第一取值为1且所述第二取值为0。
当然,在其他可替代实施例中,所述至少一个第一速率匹配图样也可称为至少一个比特位图。

示例性地,所述第一信息包括第二字段,所述第二字段的取值用于指示所述至少一个第一速率匹配图样的索引。也即是说,若所述第二字段的取值不同,则表示不同的所述至少一个第一速率匹配图样,或者说表示索引不同的所述至少一个第一速率匹配图样。
应当理解,本申请涉及的所述至少一个第一速率匹配图样的索引可以是一个索引,也可以是多个索引,本申请对此不作限定。例如,所述至少一个第一速率匹配图样的索引可以是一个索引,相当于,通过一个索引唯一性标识所述至少一个第一速率匹配图样所形成的组合,再如,所述至少一个第一速率匹配图样的索引可以包括每一个第一速率匹配图样的索引。
