Description

一种数据传输方法、装置及基站设备 技术领域
本申请涉及通信领域,尤其涉及一种数据传输方法、装置及基站设备。
背景技术
TDD(Time Division Duplex,时分双工)系统被广泛应用于移动通信系统中,如5G系统等。在TDD系统中,帧结构被分成DL(DownLink,下行)时隙、UL(UpLink,上行)时隙和S(Special,特殊)时隙。DL时隙包括多个DL符号,在这些DL符号对应的时域资源处理下行数据。UL时隙包括多个UL符号,在这些UL符号对应的时域资源处理上行数据。S时隙包括至少一个F(Flexible,灵活)符号,F符号可以用于DL,即在该F符号对应的时域资源处理下行数据,F符号也可以用于UL,即在该F符号对应的时域资源处理上行数据,F符号也可以用于GP(Guard Period,保护周期),即在该F符号对应的时域资源进行上下行切换的保护。TDD系统可以工作在HD(Half Duplex,半双工)模式中,即在同一个时刻,相同时域资源仅能用于UL或者DL。

本申请提供一种数据传输装置,应用于基站设备,包括:确定模块,用于确定SBFD时频资源和上行时频资源的重合情况;获取模块,用于基于所述重合情况、用户设备的FD能力,从所述SBFD时频资源中选取可用时频资源;传输模块,用于在所述可用时频资源上传输PDSCH对应的下行数据。

由以上技术方案可见,可以在SBFD(Sub-Band Full Duplex,子带全双工)时频资源上传输PDSCH(Physical Downlink Shared Channel,物理下行共享信道)对应的下行数据,从而更加有效的利用SBFD时频资源,提高资源利用率,能够提高网络覆盖和网络容量,同时降低传输时延,如降低下行传输时延。

具体实施方式
在本申请实施例使用的术语仅仅是出于描述特定实施例的目的,而非限制本申请。本申请和权 利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式,除非上下文清楚地表示其它含义。还应当理解,本文中使用的术语“和/或”是指包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解,尽管在本申请实施例可能采用术语第一、第二、第三等来描述各种信息,但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如,在不脱离本申请范围的情况下,第一信息也可以被称为第二信息,类似地,第二信息也可以被称为第一信息。取决于语境,此外,所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
在TDD系统中,帧结构被分成DL时隙、UL时隙和S时隙,DL时隙包括多个DL符号,在这些DL符号对应的时域资源处理下行数据,UL时隙包括多个UL符号,在这些UL符号对应的时域资源处理上行数据,S时隙包括至少一个F符号,F符号可以用于DL,也可以用于UL,还可以用于GP。当前,TDD系统可以工作在HD模式,即在同一个时刻,相同时域资源仅能用于UL或者DL。为了更加灵活的使用时域资源,并提高资源利用率,TDD系统也可以工作在FD(Full-Duplex,全双工)模式,即在同一个时刻,相同时域资源同时用于UL和DL,也就是,在相同时域资源上同时处理上行数据和下行数据。
在TDD系统下,帧结构一旦确定,用户设备就可以按照帧结构进行数据收发,而帧结构被分成DL时隙、UL时隙和S时隙。对于采用HD模式的用户设备,基站设备根据帧结构调度用户设备进行发送或者接收。对于采用FD模式的用户设备,基站设备根据帧结构调度用户设备的发送、接收或同时发送和接收。
综上所述,基站设备可以配置帧结构,并将帧结构通知给用户设备,以使用户设备能够获知帧结构,从而能够正确地进行数据收发。从另一个角度,用户设备获知帧结构之后,还可以获知可能存在的用户设备间干扰,从而可以采用一些干扰消除技术来减轻其它用户设备造成的干扰,提高通信的可靠性。
在一个例子中,在TDD系统下,针对以上行传输为主的帧结构,通常UL时隙配置较多,这就造成DL时隙变少,从而导致下行传输速率受限,并增加下行数据的传输时延,导致下行传输的时延变大,不利用下行业务。
本申请的一个例子中,提出一种数据传输方法,可以在SBFD时频资源上传输PDSCH对应的下行数据,即能够利用上行时隙或者F时隙传输PDSCH对应的下行数据,从而能够提高下行传输速率,减少下行数据的传输时延。

一个例子中,若该重合情况为SBFD时频资源中的第一时隙与上行时频资源中的第二时隙重合,且该第一时隙中的PRB与该第二时隙中的PRB不重合,那么:若FD能力为支持FD模式,上行时频资源上承载的信道类型是PUCCH类型,则可以将SBFD时频资源的第一时隙中的所有PRB选取为可用时频资源。
一个例子中,若该重合情况为SBFD时频资源中的第一时隙与上行时频资源中的第二时隙重合,且该第一时隙中的PRB与该第二时隙中的PRB重合,或者,该第一时隙中的PRB与该第二时隙中的PRB不重合,那么,若上行时频资源上承载的信道类型是PUSCH类型,且FD能力为不支持FD模式,则可以确定上行时频资源上承载的PUSCH对应的数据;若该数据为用于随机接入的数据,则可以确定SBFD时频资源为不可用时频资源。
若该数据为不用于随机接入的数据,则可以确定上行时频资源上承载的PUSCH对应的第一调度类型,并确定SBFD时频资源上承载的PDSCH对应的第二调度类型;若第一调度类型为动态调度,第二调度类型为半静态调度,则确定SBFD时频资源为不可用时频资源;若第一调度类型为半静态调度,第二调度类型为动态调度,则将SBFD时频资源中的所有PRB选取为可用时频资源。
若第一调度类型和第二调度类型均为动态调度,或者,第一调度类型和第二调度类型均为半静态调度,则可以确定上行时频资源上承载的PUSCH对应的第一优先级;确定SBFD时频资源上承载的PDSCH对应的第二优先级;若第一优先级大于第二优先级,则确定SBFD时频资源为不可用时频资源;若第一优先级小于第二优先级,则将SBFD时频资源中的所有PRB选取为可用时频资源。
若第一优先级等于第二优先级,那么:若上行时频资源上承载的PUSCH对应初传数据,且SBFD时频资源上承载的PDSCH对应重传数据,则可以确定SBFD时频资源为不可用时频资源;若上行时频资源上承载的PUSCH对应重传数据,且SBFD时频资源上承载的PDSCH对应初传数据,则可以将SBFD时频资源中的所有PRB选取为可用时频资源;若上行时频资源上承载的PUSCH对应初传数据,且SBFD时频资源上承载的PDSCH对应初传数据,则可以将SBFD时频资源中的所有PRB选取为可用时频资源;若上行时频资源上承载的PUSCH对应重传数据,且SBFD时频资源上承载的PDSCH对应重传数据,则可以将SBFD时频资源中的所有PRB选取为可用时频资源。
一个例子中,若该重合情况为SBFD时频资源中的第一时隙与上行时频资源中的第二时隙重合,且该第一时隙中的PRB与该第二时隙中的PRB重合,那么:若上行时频资源上承载的信道类型是PUSCH类型,且FD能力为支持FD模式,则可以将SBFD时频资源的第一时隙中的所有PRB选取为可用时频资源。
一个例子中,若该重合情况为SBFD时频资源中的第一时隙与上行时频资源中的第二时隙重合,且该第一时隙中的PRB与该第二时隙中的PRB不重合,那么:若FD能力为支持FD模式,上行时频资源上承载的信道类型是PUSCH类型,则可以将SBFD时频资源的第一时隙中的所有PRB选取为可用时频资源。
由以上技术方案可见,可以在SBFD时频资源上传输PDSCH对应的下行数据,从而更加有效的利用SBFD时频资源,提高资源利用率,能够提高网络覆盖和网络容量,同时降低传输时延,如降低下行传输时延。
以下结合例子,对本申请的上述技术方案进行说明。
在TDD系统下,帧结构按照时隙可以分为UL时隙、DL时隙和S时隙,S时隙中的符号可以被配置成UL符号、DL符号和灵活(F:Flexible)符号,F符号可以用于UL、DL或者GP。其中,PDSCH对应的下行数据可以在DL时隙传输,也可以在S时隙中的DL符号或者F符号传输,但是,PDSCH对应的下行数据无法在UL时隙传输,也无法在S时隙中的UL符号传输。
在TDD系统下,可以在时频资源(如UL时隙、DL时隙和S时隙)中配置SBFD时频资源,在SBFD时频资源上,可以传输与其它时频资源不同方向的数据。比如说,在UL时隙中配置SBFD时频资源,通过SBFD时频资源传输PDSCH对应的下行数据,使得PDSCH对应的下行数据在UL时隙传输。又例如,在S时隙中的UL符号配置SBFD时频资源,通过SBFD时频资源传输PDSCH对应的下行数据,使得PDSCH对应的下行数据在S时隙中的UL符号传输。
在一个例子中,SBFD符号被定义为基站设备和用户设备可以配置有SBFD子带(sub-band)的符号,在这些SBFD符号的SBFD子带上(称为SBFD时频资源),基站设备和用户设备可以进行全双工通信,也就是说,在SBFD时频资源上,可以进行上行传输、下行传输、或者上下行同时传输。SBFD时频资源可以被明确的指示为上行、下行或者Flexible,当SBFD时频资源被指示为Flexible时,可以在SBFD时频资源灵活的调度上行传输或者下行传输。
SBFD时频资源可以配置在DL符号、F符号和UL符号中,配置有SBFD时频资源的时隙也称为SBFD时隙。比如说,在DL时隙的DL符号中配置SBFD时频资源时,DL时隙也称为SBFD时隙。在UL时隙的UL符号中配置SBFD时频资源时,UL时隙也称为SBFD时隙。在S时隙的DL符号、UL符号、或F符号中配置SBFD时频资源时,S时隙也称为SBFD时隙。
对于不具备SBFD能力的用户设备来说,会忽略所有SBFD配置。对于具备SBFD能力的用户设备来说,可以在SBFD时频资源上进行上行传输、下行传输、或者上下行同时传输,后续以具备SBFD能力的用户设备为例。
对于具备SBFD能力的用户设备,一种是支持SBFD能力的半双工用户设备,即可以在SBFD时频资源上进行发送或者接收,但是在同一时刻,仅能进行发送或者接收,称为半双工用户设备。另一种是支持SBFD能力的全双工用户设备,即可以在SBFD时频资源上进行发送和接收,也就是说,在同一时刻,可以在SBFD时频资源上同时进行发送和接收,称为全双工用户设备。
在一个例子中,SBFD时频资源可以为半静态配置的SBFD时频资源,如通过RRC(Radio Resource Control,无线资源控制)信令半静态配置SBFD时频资源。SBFD时频资源也可以为动态配置的SBFD时频资源,如通过DCI(Downlink Control Information,下行控制信息)信令动态配置SBFD时频资源。
在一个例子中,可以在SBFD时频资源传输PDSCH对应的下行数据,比如说,在UL时隙中配置SBFD时频资源,通过SBFD时频资源传输PDSCH对应的下行数据,从而在UL时隙的SBFD时频资源中调度PDSCH。通过明确基站设备和用户设备在SBFD时频资源中对PDSCH的调度策略,可以在TDD系统中实现基于SBFD时频资源的下行传输,提高TDD系统的整体性能。
为了在SBFD时频资源传输PDSCH对应的下行数据,可以根据SBFD时频资源(即PDSCH使用的时频资源)和上行时频资源(即上行数据占用的时频资源)的重合情况、用户设备的FD能力(如支持FD模式或者不支持FD模式),确定PDSCH在SBFD时频资源中的调度策略,使基站设 备和用户设备能够有明确传输机制,实现基站设备和用户设备间基于SBFD时频资源的全双工通信。
在一个例子中,PDSCH中承载的下行数据可以包括但不限于应用数据和下行公共控制信息,下行公共控制信息可以包括但不限于SIB(System Information Block,系统信息块)、寻呼信息、2步随机接入过程中的消息B(MSG-B)、4步随机介入过程中的消息2(MSG2)、4步随机介入过程中的消息4(MSG4)等。其中,基于PDSCH中承载的上述数据,PDSCH传输的可以是初传数据,也可以是基于HARQ(Hybrid Automatic Repeat reQuest,混合自动重传请求)反馈的重传数据,还可以是半静态配置的重复传输数据,对此不作限制。
参见图2所示,为在SBFD时频资源中调度PDSCH的示意图,若SBFD时频资源在DL符号或F符号中,则PDSCH对应的下行数据可以跨SBFD时频资源进行传输,即部分下行数据在SBFD时频资源之内传输,另一部分下行数据在SBFD时频资源之外传输。在图2中,针对时隙0和时隙1,PDSCH对应的下行数据可以在SBFD时频资源之内传输,也可以在SBFD时频资源之外传输。
若SBFD时频资源在UL符号中,则PDSCH对应的下行数据仅能在SBFD时频资源内进行传输,而不能使用SBFD时频资源之外的UL资源。其中,对于动态调度的PDSCH,可以通过DCI在SBFD时频资源中调度PDSCH,而对于SPS(Semi-Persistent Scheduling,半持续调度)的PDSCH,如果SPS调度的PDSCH超出SBFD时频资源范围,则PDSCH仅在SBFD时频资源内发送。在图2中,针对时隙2和时隙3,PDSCH对应的下行数据只能在SBFD时频资源之内传输。
在一个例子中,由于SBFD时频资源会与上行时频资源重合,因此,可以根据SBFD时频资源和上行时频资源的重合情况、用户设备的FD能力、上行时频资源上承载的信号类型或信道类型等信息,综合考虑PDSCH的传输策略。
比如说,可以从SBFD时频资源中选取可用时频资源,并在可用时频资源上传输PDSCH对应的下行数据。或者,可以将SBFD时频资源确定为不可用时频资源,不在SBFD时频资源上传输PDSCH对应的下行数据。
情况一、SBFD时频资源与PRACH上行时频资源的冲突情况,即,SBFD时频资源承载的PDSCH和上行时频资源承载的PRACH发生冲突。
针对PRACH与动态配置的SBFD时频资源的冲突情况。
由于基站设备明确知道PRACH上行时频资源的位置,为了保证用户设备能够正常使用PRACH发送接入前导,完成用户设备的初始接入,基站设备需要避免在PRACH占用的上行时频资源中动态配置SBFD时频资源。从用户设备的角度,用户设备也不期待在与PRACH重合的上行时频资源上被动态配置SBFD时频资源。其中,PRACH上行时频资源(符号)对应的上行数据可以包括RACH机会(RO:RACH Occasion)和RO之前可能存在的GP符号。
针对PRACH与半静态配置的SBFD时频资源的冲突情况。
对于半双工用户设备,在用户设备未接入网络时,用户设备需要随时准备接入网络,所以PRACH上行时频资源不能被占用,不能在与PRACH上行时频资源冲突的SBFD时频资源中发送PDSCH对应的下行数据,如SIB1等。对于动态调度的PDSCH,可以通过动态调度避免在冲突的SBFD时频资源上发送PDSCH对应的下行数据。对于半持续调度的PDSCH,基站设备在与PRACH上行时频资源冲突的SBFD时频资源不发送PDSCH对应的下行数据,用户设备也不会在与PRACH上行时频资源冲突的SBFD时频资源中接收下行数据。
对于半双工用户设备,在用户设备接入网络的过程中,PRACH上行时频资源(即RO资源)在MSG 1(4步RACH)或者MSG A(2步RACH)中使用,PDSCH在MSG 2、MSG 4(4步RACH)或者MSG B(2步RACH)中使用,即PRACH和PDSCH不同时使用。但是,考虑到PRACH上行时频资源是多个用户共享,在与PRACH上行时频资源冲突的SBFD时频资源,向一个用户设备发送PDSCH对应的下行数据时,会影响其它用户设备接收PRACH,因此,在与PRACH上行时频资源冲突的SBFD时频资源不发送PDSCH对应的下行数据。
对于半双工用户设备,在用户设备接入网络后不再需要PRACH上行时频资源,但是,其它未接入网络的用户设备可能在PRACH上行时频资源上发起随机接入,在与PRACH上行时频资源冲突的SBFD时频资源,向一个用户设备发送PDSCH对应的下行数据时,会影响其它用户设备接收PRACH,因此,在与PRACH上行时频资源冲突的SBFD时频资源不发送PDSCH对应的下行数据。
综上所述,对于半双工用户设备,考虑到PRACH的重要性,当SBFD时频资源与PRACH上行时频资源有重合时,在任意与PRACH符号重合的SBFD符号中,基站设备不会发送PDSCH对应的下行数据,即不会发送动态调度PDSCH对应的下行数据,也不会发送半静态调度PDSCH对应的下行数据,相应地,用户设备也不在SBFD时频资源中接收PDSCH对应的下行数据。
对于半双工用户设备,即不支持FD模式,上行时频资源上承载的信道类型是PRACH类型时,若SBFD时频资源中的第一时隙与PRACH上行时频资源中的第二时隙重合,无论第一时隙中的PRB与第二时隙中的PRB重合,还是第一时隙中的PRB与第二时隙中的PRB不重合,均确定SBFD时频资源为不可用时频资源,即不在SBFD时频资源发送PDSCH对应的下行数据。若SBFD时频资源中的第一时隙与PRACH上行时频资源中的第二时隙不重合,确定SBFD时频资源为可用时频资源,即在SBFD时频资源发送PDSCH对应的下行数据。
将SBFD时频资源中的时隙称为第一时隙,将PRACH上行时频资源中的时隙称为第二时隙,若第一时隙和第二时隙相同,则SBFD时频资源中的第一时隙与PRACH上行时频资源中的第二时隙重合,若第一时隙和第二时隙不同,则SBFD时频资源中的第一时隙与PRACH上行时频资源中的第二时隙不重合。
针对PRACH与半静态配置的SBFD时频资源的冲突情况。
对于全双工用户设备,若PRACH上行时频资源与SBFD时频资源重合,如PRACH上行时频资源中的PRB与SBFD时频资源中的PRB重合(部分重合或者完全重合),参见图3所示,为部分重合的示意图,F表示灵活时隙,可以用于上行或者下行,DL表示下行时隙,UL表示上行时隙。在图3中,时隙4中的PRACH上行时频资源与SBFD时频资源有部分重合,阴影部分表示与PRACH上行时频资源重合的SBFD时频资源,即阴影部分表示重合部分的PRB。
在进行随机接入之前,用户设备需要通过PDSCH接收SIB1,获得PRACH配置信息,并基于PRACH配置信息进行随机接入。基站设备在与PRACH上行时频资源重合的SBFD时频资源发送SIB1时,SIB1会对PRACH前导的检测性能造成影响,用户设备在发送PRACH前导时也会对其接收SIB1造成影响。
由于PRACH前导和SIB1都是重要信息,因此,需要避免在PRACH上行时频资源上调度SIB1,从而避免对二者造成干扰。当然,在基站设备通过PDSCH传输其它下行数据时,也需要避免对PRACH前导的传输造成影响。
综上所述,PRACH上行时频资源中的PRB与SBFD时频资源中的PRB有重合时,用户设备不期待在重合的SBFD时频资源上调度任何PDSCH,对于半持续调度的PDSCH,基站设备不在重合的SBFD时频资源上发送PDSCH,相应地,用户设备也不期待在重合的SBFD时频资源上接收PDSCH。
综上可以看出,对于全双工用户设备,即支持FD模式,上行时频资源上承载的信道类型是PRACH类型时,若SBFD时频资源中的第一时隙与PRACH上行时频资源中的第二时隙重合,且第一时隙中的PRB与第二时隙中的PRB重合,则可以确定SBFD时频资源为不可用时频资源,即不在SBFD时频资源发送PDSCH对应的下行数据。若SBFD时频资源中的第一时隙与PRACH上行时频资源中的第二时隙不重合,则可以确定SBFD时频资源为可用时频资源。
对于全双工用户设备,若PRACH上行时频资源与SBFD时频资源不重合,如PRACH上行时频资源中的PRB与SBFD时频资源中的PRB不重合,参见图4所示,为在相同符号的时频资源不重合的示意图,与重合情况不同的是,PRB不重合时仅存在子带间干扰,相比子带内干扰,子带间干扰会更小。
基于此,可以采用如下方案进行处理:方案一、在与PRACH符号重合的SBFD符号的任何时频资源都不发送PDSCH对应的下行数据。方案二、在所有SBFD时频资源中发送PDSCH对应的下行数据。对于动态调度的PDSCH和PDSCH重复传输,基站设备可以确定是否在SBFD时频资源中调度PDSCH,并将调度信息通过DCI发送给用户设备,而用户设备根据调度信息进行PDSCH的接收。对于半持续调度,如果SBFD时频资源与PRACH上行时频资源不存在任何时频资源的重合,则基站设备在SBFD时频资源发送PDSCH对应的下行数据,而用户设备在SBFD时频资源接收PDSCH对应的下行数据。
综上可以看出,对于全双工用户设备,即支持FD模式,上行时频资源上承载的信道类型是 PRACH类型时,若SBFD时频资源中的第一时隙与PRACH上行时频资源中的第二时隙重合,且第一时隙中的PRB与第二时隙中的PRB不重合,则:将SBFD时频资源的第一时隙中的所有PRB选取为可用时频资源,并在SBFD时频资源发送PDSCH对应的下行数据,即在所有SBFD时频资源中发送PDSCH对应的下行数据(方案二)。或者,可以确定SBFD时频资源为不可用时频资源,即不在SBFD时频资源发送PDSCH对应的下行数据(方案一)。
情况二、SBFD时频资源与SRS上行时频资源的冲突情况,即,SBFD时频资源承载的PDSCH和上行时频资源承载的SRS发生冲突。
在一个例子中,SRS用于上行波束管理、预编码、天线切换等功能,SRS是通过RRC信令半静态配置,SRS可以被配置成周期性、半持续性和非周期性。对于周期性的SRS,在配置完成时即被激活,对于半持续性的SRS,需要通过MAC CE进行激活,对于非周期性的SRS,需要通过DCI进行激活。
当存在激活的SRS与SBFD时频资源重合的情况时,可以根据用户设备的FD能力,确定PDSCH在SBFD时频资源中的传输策略。
对于半双工用户设备,需要明确用户设备在与SRS重合的SBFD时频资源中如何处理PDSCH。如果PDSCH是动态调度,那么,基站设备不在SRS上行时频资源(如SRS所占用符号以及SRS符号之前的至少一个符号(用于GP)等)中调度PDSCH以及PDSCH重复传输,用户设备不期待在SRS上行时频资源中接收PDSCH和PDSCH重复传输。此外,如果PDSCH和PDSCH重复传输是SPS,PDSCH的时频资源是在SPS激活过程中通过DCI发送给用户设备,那么,基站设备在为PDSCH以及PDSCH重复传输分配时频资源时,不在SRS上行时频资源中为PDSCH以及PDSCH重复传输分配时频资源,用户设备也不在SRS上行时频资源中接收PDSCH和PDSCH重复数据。
综上可以看出,对于半双工用户设备,上行时频资源上承载的信号类型是SRS类型时,若SBFD时频资源中的第一时隙与SRS上行时频资源中的第二时隙重合,无论第一时隙中的PRB与第二时隙中的PRB重合,还是第一时隙中的PRB与第二时隙中的PRB不重合,均确定SBFD时频资源为不可用时频资源,即不在SBFD时频资源发送PDSCH对应的下行数据。若SBFD时频资源中的第一时隙与SRS上行时频资源中的第二时隙不重合,确定SBFD时频资源为可用时频资源,即在SBFD时频资源发送PDSCH对应的下行数据。
对于全双工用户设备,若SRS上行时频资源与SBFD时频资源不重合,如SRS上行时频资源中的PRB与SBFD时频资源中的PRB不重合,比如说,在同一个符号中占用不同的PRB资源,或者,在不同符号中占用相同的PRB资源,那么,基站设备可以在SBFD时频资源中发送PDSCH对应的下行数据,用户设备可以在相应的SBFD时频资源上接收PDSCH对应的下行数据。
综上可以看出,对于全双工用户设备,上行时频资源上承载的信号类型是SRS类型时,若SBFD时频资源中的第一时隙与SRS上行时频资源中的第二时隙重合,第一时隙中的PRB与第二时隙中的PRB不重合,则将SBFD时频资源的第一时隙中的所有PRB选取为可用时频资源,在SBFD时频资源发送PDSCH对应的下行数据,即在所有SBFD时频资源中发送PDSCH对应的下行数据。若SBFD时频资源中的第一时隙与SRS上行时频资源中的第二时隙不重合,确定SBFD时频资源为可用时频资源,在SBFD时频资源发送PDSCH对应下行数据。
对于全双工用户设备,若SRS上行时频资源与SBFD时频资源重合,如SRS上行时频资源中的PRB与SBFD时频资源中的PRB重合,参见图5所示,为SBFD时频资源中的PRB与SRS上行时频资源中的PRB重合的示意图,SBFD时频资源占据#190-#193等PRB,而SRS上行时频资源占据符号#12-符号#13中的272个PRB,SRS上行时频资源在每个PRB中占据RE#0,#5,#9。
对于动态调度的PDSCH,PDSCH占用的时频资源由基站设备通过DCI发送给用户设备,当PDSCH在与SRS重合的SBFD时频资源上传输时,可以采用如下方案:方案一:基站设备不在与SRS重合的SBFD时频资源中调度PDSCH,用户设备也不在与SRS重合的SBFD时频资源中接收PDSCH对应的下行数据。
在方案一中,基站设备可以判断与SRS重合的SBFD时频资源,在其余未重合的时频资源上调度PDSCH,并将PDSCH使用的时频资源通过DCI发送给用户设备,用户设备根据调度信息接收PDSCH对应的下行数据。
综上可以看出,对于全双工用户设备,上行时频资源上承载的信号类型是SRS类型时,若 SBFD时频资源中的第一时隙与SRS上行时频资源中的第二时隙重合,第一时隙中的PRB与第二时隙中的PRB重合,则将SBFD时频资源的第一时隙中的目标PRB选取为可用时频资源,在可用时频资源发送PDSCH对应的下行数据,即在SBFD时频资源的部分时频资源发送PDSCH对应的下行数据,而不是在SBFD时频资源的所有时频资源发送PDSCH对应的下行数据。其中,目标PRB可以为SRS上行时频资源中未占用符号中的PRB,即从SBFD时频资源排除SRS上行时频资源占用的符号,在剩余符号的PRB发送PDSCH对应的下行数据,不在SRS上行时频资源占用的符号发送PDSCH对应的下行数据。
在一个例子中,对于PDSCH重复传输,可能出现某些PDSCH重复传输对应的时频资源与SRS上行时频资源不重合,但其它PDSCH重复传输对应的时频资源与SRS上行时频资源重合的情况,该情况下可以采用如下方式:
方式A、基于与SRS上行时频资源重合的SBFD时频资源,基站设备保证所有在SBFD时频资源传输的PDSCH(如多个PDSCH重复传输)不会与SRS上行时频资源冲突,即所有PDSCH重复传输使用的均是SRS上行时频资源未占用符号中的PRB。用户设备根据基站设备的调度信息接收PDSCH重复传输。
在方式A中,针对PDSCH初传和每个PDSCH重复传输(即PDSCH对应的每个重复传输的下行数据),可以从SBFD时频资源的第一时隙中选取目标PRB,目标PRB可以为SRS上行时频资源未占用符号中的PRB,也就是说,将SRS上行时频资源未占用符号中的PRB作为目标PRB参与PDSCH重复传输。然后,可以将目标PRB选取为可用时频资源,并在可用时频资源上传输PDSCH对应的重复传输,或者,在可用时频资源上传输PDSCH初传对应的下行数据。
方式B、基站设备根据实际数据大小配置PDSCH传输所用的时频资源,对于与SRS上行时频资源重合的SBFD时频资源上的PDSCH,在SBFD时频资源的与SRS上行时频资源未重合的资源上传输PDSCH对应的下行数据。比如说,针对PDSCH初传和多个PDSCH重复传输,可以使用SRS上行时频资源未占用的PRB。SRS上行时频资源未占用的PRB可以为SRS上行时频资源未占用符号中的PRB,也可以为SRS上行时频资源已占用符号的PRB。
参见图6所示,为PDSCH重复传输与SRS上行时频资源重合的示意图,PDSCH初传在时隙3中,而PDSCH重复传输在时隙4中与SRS上行时频资源重合,在该情况下,在时隙3中正常传输PDSCH对应的所有下行数据,但是,在时隙4的PDSCH重复传输过程中,只能在未重合的SBFD时频资源中传输部分下行数据。同理,如果PDSCH初传的时频资源与SRS上行时频资源重合,则PDSCH初传对应的下行数据仅在未重合的SBFD时频资源中传输。
在方式B中,针对PDSCH初传和每个PDSCH重复传输,可以从SBFD时频资源的第一时隙中选取目标PRB,目标PRB可以为SRS上行时频资源未占用的PRB,也就是说,可以将SRS上行时频资源未占用的PRB作为目标PRB参与PDSCH初传或者PDSCH重复传输。然后,可以将目标PRB选取为可用时频资源,并在可用时频资源上传输PDSCH对应的下行数据。
在一个例子中,对于基于HARQ反馈的PDSCH重传,需要DCI进行调度。如果与SRS上行时频资源不重合的SBFD时频资源足够PDSCH重传,则基站设备在SBFD时频资源中调度PDSCH重传,用户设备按照调度信息接收PDSCH重传对应的下行数据。如果与SRS上行时频资源不重合的SBFD时频资源不足以发送PDSCH重传对应的下行数据,那么,基站设备可以不在SBFD时频资源中调度PDSCH重传,用户设备也不会在SBFD时频资源中接收PDSCH重传对应的下行数据。或者,基站设备在SBFD时频资源中调度PDSCH重传,但是,基站设备根据可用的资源大小,仅发送部分PDSCH重传数据,而用户设备也根据调度信息在未重合的SBFD时频资源中接收PDSCH重传数据。
方案二:PDSCH对应的下行数据在SBFD时频资源中围绕SRS做速率匹配,在方案二中,基站设备在与SRS上行时频资源重合的SBFD时频资源中调度PDSCH,但是,PDSCH对应的下行数据在SRS上行时频资源未占用的所有RE中发送。参见图5所示,在符号#12-符号#13中除RE#0,#5,#9之外的所有RE,均可以用于传输PDSCH对应的下行数据,可以在这些RE进行速率匹配。
综上可以看出,对于全双工用户设备,上行时频资源上承载的信号类型是SRS类型时,若SBFD时频资源中的第一时隙与SRS上行时频资源中的第二时隙重合,第一时隙中的PRB与第二时隙中的PRB重合,则可以从SBFD时频资源的第一时隙中选取目标PRB,目标PRB包括SRS上行时频资源中未占用的第一RE资源和已占用的第二RE资源,将目标PRB的第一RE资源选取为可 用时频资源,在可用时频资源发送PDSCH对应的下行数据,即,在SBFD时频资源的目标PRB的部分时频资源发送PDSCH对应的下行数据。
其中,目标PRB可以为SRS上行时频资源中已占用的PRB,即SRS上行时频资源已占用目标PRB的部分RE,可以从目标PRB中排除SRS上行时频资源占用的RE,在剩余RE资源发送PDSCH对应的下行数据。
在一个例子中,对于SRS占用的上行时频资源的位置,基站设备会通过RRC信令配置给用户设备,对于半持续性的SRS,基站设备通过MAC CE命令对SRS进行激活,对于非周期性的SRS,基站设备通过DCI命令对SRS进行激活,因此,基站设备根据有效的SRS资源位置对PDSCH做速率匹配,用户设备也根据SRS资源的配置,围绕SRS对PDSCH做解速率匹配。
比如说,在一个BWP内,用户设备可以被配置一个或者多个周期性、半持续性或者非周期性的SRS资源集合,每个资源集合中可以最多包含16个SRS资源。其中,对于周期性的SRS来说,所有被srs-ResourceSetToAddModList和srs-ResourceToAddModList配置的SRS的RE资源,这些RE资源均不能够被PDSCH使用。对于半持续性的SRS来说,所有被srs-ResourceSetToAddModList和srs-ResourceToAddModList配置、并被MAC CE激活的SRS的RE资源,这些RE资源均不能够被PDSCH使用。对于非周期性的SRS资源来说,所有被srs-ResourceSetToAddModList和srs-ResourceToAddModList配置、并被DCI激活的SRS的RE资源,这些RE资源均不能够被PDSCH使用。
同理,对于在与SRS上行时频资源重合的SBFD时频资源中传输的PDSCH重复传输和基于HARQ反馈的PDSCH重传,均需要在SRS重合的SBFD时频资源中,按照如上方案围绕SRS做速率匹配,在此不再重复赘述。
从用户设备的角度,对于单次PDSCH传输和基于HARQ反馈的PDSCH传输,采用哪一种方案(方案一或者方案二)可以在动态调度过程中确定。如果用户设备判断动态调度的PDSCH所占用的SBFD时频资源未与SRS上行时频资源重合,则可以确定是方案一,否则可以确定是方案二,用户设备可以围绕SRS对PDSCH进行解速率匹配。对于PDSCH重复传输,用户设备无法根据PDSCH重复传输的参数判断采用哪种方案,因此可以有专门的指示参数。
其中,PDSCH重复传输的个数是通过RRC参数pdsch-AggregationFactor(聚合因子)或者RepetitionSchemeConfig(重复方案配置)-r16配置,因此,在与SRS上行时频资源重合的SBFD时频资源中进行PDSCH重复传输时,也通过RRC参数来指示采用哪个方案。
比如说,当通过pdsch-AggregationFactor配置来指示采用方案一还是方案二时,可以引入一个新的参数pdsch-AggregationMultiplexingWithSRSInSbfd:pdsch-AggregationMultiplexingWithSRSInSbfd ENUMERATED{noTx,rm}option,可以将这个参数称为pdsch重复传输与srs复用方式的指示参数。如果pdsch-AggregationFactor未配置,那么pdsch-AggregationMultiplexingWithSRS InSbfd也不配置。如果pdsch-AggregationFactor配置,那么pdsch-Aggregation MultiplexingWithSRSInSbfd就用于指示采用方案一还是方案二。比如说,从两个选项(noTx、rm)中选择其中一个,noTx表示不传,该选项对应方案一,即采用方案一处理,rm表示做速率匹配,该选项对应方案二,即采用方案二处理。
比如说,当通过RepetitionSchemeConfig-r16配置来指示采用方案一还是方案二时,可以引入一个新的参数RepetitionMultiplexingWithSRS:Repetition MultiplexingWithSRS ENUMERATED{noTx,rm}option,可以将这个参数称为pdsch重复传输与srs复用方式的指示参数。如果RepetitionScheme Config-r16未配置,那么RepetitionMultiplexingWithSRS也不配置。如果Repetition SchemeConfig-r16配置,那么,RepetitionMultiplexingWithSRS就用于指示采用方案一还是方案二。比如说,从两个选项(noTx、rm)中选择其中一个,noTx表示不传,该选项对应方案一,rm表示做速率匹配,该选项对应方案二。
对于上述各参数来说,如果RepetitionSchemeConfig-r16被配置,那么,pdsch-AggregationFactor不再被配置,如果RepetitionMultiplexingWithSRS被配置,那么,pdsch-AggregationMultiplexingWithSRSInSbfd不再被配置。
在一个例子中,对于半持续调度(SPS)的PDSCH,PDSCH所占用的时频资源会在半静态配置被激活时通过DCI发送给用户设备,因此,上述方式也可以用于SPS PDSCH、SPS PDSCH重复传输、基于HARQ反馈的重传。
情况三、SBFD时频资源与PUCCH上行时频资源的冲突情况,即,SBFD时频资源承载的PDSCH和上行时频资源承载的PUCCH发生冲突。
在一个例子中,PUCCH用于传输SR(Scheduling Request,调度请求)、HARQ反馈以及CSI(Channel State Information,信道状态信息)上报。PUCCH分为多个格式,分别是PUCCH格式0/1/2/3/4,PUCCH格式0/2是短PUCCH,长度是1个或2个符号,PUCCH格式1/3/4是长PUCCH,长度从4-14个符号不等。当存在PUCCH上行时频资源与SBFD时频资源重合的情况时,可以根据用户设备的FD能力,确定PDSCH在SBFD时频资源中的传输策略。
对于半双工用户设备,需要明确用户设备在与PUCCH重合的SBFD时频资源中如何处理PDSCH。如果PDSCH是动态调度,那么,基站设备不在PUCCH上行时频资源(如PUCCH所占用符号及PUCCH之前的至少一个符号(用于GP)等)中调度PDSCH和PDSCH重复传输,用户设备不期待在PUCCH上行时频资源中接收PDSCH和PDSCH重复传输。如果PDSCH是半持续调度,那么,基站设备不在PUCCH上行时频资源中调度PDSCH和PDSCH重复传输,用户设备不期待在PUCCH上行时频资源中接收PDSCH和PDSCH重复传输。
综上可以看出,对于半双工用户设备,上行时频资源上承载的信道类型是PUCCH类型时,若SBFD时频资源中的第一时隙与PUCCH上行时频资源中的第二时隙重合,无论第一时隙中的PRB与第二时隙中的PRB重合,还是第一时隙中的PRB与第二时隙中的PRB不重合,均确定SBFD时频资源为不可用时频资源,即不在SBFD时频资源发送PDSCH对应的下行数据。若SBFD时频资源中的第一时隙与PUCCH上行时频资源中的第二时隙不重合,确定SBFD时频资源为可用时频资源,即在SBFD时频资源发送PDSCH对应的下行数据。
对于全双工用户设备,若PUCCH上行时频资源与SBFD时频资源不重合,如PUCCH上行时频资源中的PRB与SBFD时频资源中的PRB不重合,比如说,在同一个符号中占用不同的PRB资源,或者,在不同符号中占用相同的PRB资源,那么,基站设备可以在SBFD时频资源中发送PDSCH对应的下行数据,用户设备可以在相应的SBFD时频资源上接收PDSCH对应的下行数据,也就是说,用户设备可以在发送PUCCH的同时,接收PDSCH对应的下行数据。
综上可以看出,对于全双工用户设备,上行时频资源上承载的信道类型是PUCCH类型时,若SBFD时频资源中的第一时隙与PUCCH上行时频资源中的第二时隙重合,第一时隙中的PRB与第二时隙中的PRB不重合,则将SBFD时频资源的第一时隙中的所有PRB选取为可用时频资源,在SBFD时频资源发送PDSCH对应的下行数据,即在所有SBFD时频资源中发送下行数据。若SBFD时频资源中的第一时隙与PUCCH上行时频资源中的第二时隙不重合,确定SBFD时频资源为可用时频资源,在SBFD时频资源发送PDSCH对应下行数据。
对于全双工用户设备,若PUCCH上行时频资源与SBFD时频资源重合,如PUCCH上行时频资源中的PRB与SBFD时频资源中的PRB重合,参见图7所示,为SBFD时频资源中的PRB与PUCCH上行时频资源中的PRB重合的示意图,显然,SBFD时频资源占据#190-#193等PRB,而PUCCH上行时频资源(如PUCCH格式3)占据符号#10-符号#13中的16个PRB。
对于动态调度的PDSCH,PDSCH占用的时频资源由基站设备通过DCI发送给用户设备,当PDSCH在与PUCCH重合的SBFD时频资源上传输时,可以采用如下方案:方案一:基站设备不在与PUCCH重合的SBFD时频资源中调度PDSCH,用户设备也不在与PUCCH重合的SBFD时频资源中接收PDSCH对应的下行数据。在方案一中,基站设备可以判断与PUCCH重合的SBFD时频资源,在其余未重合的时频资源上调度PDSCH,并将PDSCH使用的时频资源通过DCI发送给用户设备,用户设备根据调度信息接收PDSCH对应的下行数据。
综上可以看出,对于全双工用户设备,上行时频资源上承载的信道类型是PUCCH类型时,若SBFD时频资源中的第一时隙与PUCCH上行时频资源中的第二时隙重合,第一时隙中的PRB与第二时隙中的PRB重合,则将SBFD时频资源的第一时隙中的目标PRB选取为可用时频资源,在可用时频资源发送PDSCH对应的下行数据,即在SBFD时频资源的部分时频资源发送PDSCH对应的下行数据。其中,目标PRB可以为PUCCH上行时频资源中未占用符号中的PRB,即从SBFD时频资源排除PUCCH上行时频资源占用的符号,在剩余符号的PRB发送PDSCH对应的下行数据,不在PUCCH上行时频资源占用的符号发送PDSCH对应的下行数据。
在一个例子中,对于PDSCH重复传输,可能出现某些PDSCH重复传输对应的时频资源与PUCCH上行时频资源不重合,但其它PDSCH重复传输对应的时频资源与PUCCH上行时频资源重 合的情况,该情况下可以采用如下方式:
方式A、基于与PUCCH上行时频资源重合的SBFD时频资源,基站设备保证所有在SBFD时频资源传输的PDSCH(如多个PDSCH重复传输)不会与PUCCH上行时频资源冲突,即所有PDSCH重复传输使用的均是PUCCH上行时频资源未占用符号中的PRB。用户设备根据基站设备的调度信息接收PDSCH重复传输。在方式A中,针对PDSCH初传和每个PDSCH重复传输(即PDSCH对应的每个重复传输的下行数据),可以从SBFD时频资源的第一时隙中选取目标PRB,目标PRB可以为PUCCH上行时频资源未占用符号中的PRB,即将PUCCH上行时频资源未占用符号中的PRB作为目标PRB参与PDSCH重复传输。然后,可以将目标PRB选取为可用时频资源,并在可用时频资源上传输PDSCH对应的重复传输,或者,在可用时频资源上传输PDSCH初传对应的下行数据。
方式B、基站设备根据实际数据大小配置PDSCH传输所用的时频资源,对于与PUCCH上行时频资源重合的SBFD时频资源上的PDSCH,在SBFD时频资源的与PUCCH上行时频资源未重合的资源上传输PDSCH对应的下行数据。比如说,针对PDSCH初传和多个PDSCH重复传输,可以使用PUCCH上行时频资源未占用的PRB。PUCCH上行时频资源未占用的PRB可以为PUCCH上行时频资源未占用符号中的PRB,或PUCCH上行时频资源已占用符号的PRB。
参见图8所示,为PDSCH重复传输与PUCCH上行时频资源重合的示意图,PDSCH初传在时隙3中,而PDSCH重复传输在时隙4中与PUCCH上行时频资源重合,在该情况下,在时隙3中正常传输PDSCH对应的所有下行数据,但是,在时隙4的PDSCH重复传输过程中,只能在未重合的SBFD时频资源中传输部分下行数据。同理,如果PDSCH初传的时频资源与PUCCH上行时频资源重合,则PDSCH初传对应的下行数据仅在未重合的SBFD时频资源中传输。
在方式B中,针对PDSCH初传和每个PDSCH重复传输,可以从SBFD时频资源的第一时隙中选取目标PRB,目标PRB可以为PUCCH上行时频资源未占用的PRB,也就是说,可以将PUCCH上行时频资源未占用的PRB作为目标PRB参与PDSCH初传或者PDSCH重复传输。然后,可以将目标PRB选取为可用时频资源,并在重可用频资源上传输PDSCH对应的下行数据。
在一个例子中,对于基于HARQ反馈的PDSCH重传,需要DCI进行调度。如果与PUCCH上行时频资源不重合的SBFD时频资源足够PDSCH重传,则基站设备在SBFD时频资源中调度PDSCH重传,用户设备按照调度信息接收PDSCH重传对应的下行数据。如果与PUCCH上行时频资源不重合的SBFD时频资源不足以发送PDSCH重传对应的下行数据,那么,基站设备可以不在SBFD时频资源中调度PDSCH重传,用户设备也不会在SBFD时频资源中接收PDSCH重传对应的下行数据。或者,基站设备在SBFD时频资源中调度PDSCH重传,但是,基站设备根据可用的资源大小,仅发送部分PDSCH重传数据,而用户设备也根据调度信息在未重合的SBFD时频资源中接收PDSCH重传数据。
方案二:PDSCH对应的下行数据在SBFD时频资源中围绕PUCCH做速率匹配,在方案二中,基站设备在与PUCCH上行时频资源重合的SBFD时频资源中调度PDSCH,但是,PDSCH对应的下行数据在PUCCH上行时频资源未占用的所有PRB中发送。与SRS不同的是,PDSCH围绕SRS做RE级别的速率匹配,而PDSCH围绕PUCCH做PRB级别的速率匹配。参见图7所示,符号#10-符号#13中除PRB#0-#15之外的所有PRB都可以用于PDSCH传输。综上可以看出,对于全双工用户设备,上行时频资源上承载的信道类型是PUCCH类型时,若SBFD时频资源中的第一时隙与PUCCH上行时频资源中的第二时隙重合,第一时隙中的PRB与第二时隙中的PRB重合,则可以从SBFD时频资源的第一时隙中选取目标PRB,目标PRB为PUCCH上行时频资源中未占用的PRB,将目标PRB选取为可用时频资源,在可用时频资源发送PDSCH对应的下行数据。
在一个例子中,对于PUCCH占用的时频资源的位置,基站设备通过RRC信令配置给用户设备,基站设备可以根据有效的PUCCH资源位置对PDSCH做速率匹配,用户设备根据PUCCH的配置,围绕PUCCH时频资源对PDSCH做解速率匹配。同理,对于在与PUCCH上行时频资源重合的SBFD时频资源中传输的PDSCH重复传输和基于HARQ反馈的PDSCH重传,均需要在PUCCH重合的SBFD时频资源中,按照如上方案围绕PUCCH做速率匹配,在此不再赘述。
从用户设备的角度,对于单次PDSCH传输和基于HARQ反馈的PDSCH传输,采用哪一种方案(方案一或者方案二)可以在动态调度过程中确定。如果用户设备判断动态调度的PDSCH所占用的SBFD时频资源未与PUCCH上行时频资源重合,则可以确定是方案一,否则可以确定是方案二,用户设备可以围绕PUCCH对PDSCH进行解速率匹配。对于PDSCH重复传输,用户设备 无法根据PDSCH重复传输的参数判断采用哪种方案,因此可以有专门的指示参数。
其中,PDSCH重复传输的个数通过RRC参数pdsch-AggregationFactor或者RepetitionSchemeConfig-r16配置,因此,在与PUCCH上行时频资源重合的SBFD时频资源中进行PDSCH重复传输时,也通过RRC参数来指示采用哪个方案。
比如说,当通过pdsch-AggregationFactor配置来指示采用方案一还是方案二时,可以引入新的参数pdsch-AggregationMultiplexingWithPUCCHInSbfd:pdsch-AggregationMultiplexingWithPUCCHInSbfd ENUMERATED{noTx,rm}option,可以将这个参数称为pdsch重复传输与pucch复用方式的指示参数。如果pdsch-AggregationFactor未配置,pdsch-AggregationMultiplexingWithPUCCH InSbfd也不配置。如果pdsch-AggregationFactor配置,那么pdsch-Aggregation MultiplexingWithPUCCHInSbfd就用于指示采用方案一还是方案二。比如说,从两个选项(noTx、rm)中选择一个,noTx表示不传,该选项对应方案一,即采用方案一处理,rm表示做速率匹配,该选项对应方案二,即采用方案二处理。
比如说,当通过RepetitionSchemeConfig-r16配置来指示采用方案一还是方案二时,可以引入一个新的参数RepetitionMultiplexingWithPUCCH:Repetition MultiplexingWithPUCCH ENUMERATED{noTx,rm}option,可以将这个参数称为pdsch重复传输与pucch复用方式的指示参数。如果Repetition SchemeConfig-r16未配置,RepetitionMultiplexingWithPUCCH也不配置。如果Repetition SchemeConfig-r16配置RepetitionMultiplexingWithPUCCH就用于指示采用方案一还是方案二。比如说,从两个选项(noTx、rm)中选择其中一个,noTx表示不传,该选项对应方案一,rm表示做速率匹配,该选项对应方案二。
对于上述各参数来说,如果RepetitionSchemeConfig-r16被配置,那么,pdsch-AggregationFactor不再被配置,如果RepetitionMultiplexingWithPUCCH被配置,那么,pdsch-AggregationMultiplexingWithPUCCHInSbfd不再被配置。
在一个例子中,对于半持续调度(SPS)的PDSCH,PDSCH所占用的时频资源会在半静态配置被激活时通过DCI发送给用户设备,因此,上述方式也可以用于SPS PDSCH、SPS PDSCH重复传输、基于HARQ反馈的重传。
情况四、SBFD时频资源与PUSCH上行时频资源的冲突情况,即,SBFD时频资源承载的PDSCH和上行时频资源承载的PUSCH发生冲突。
在一个例子中,PUSCH用于传输上行数据,PUSCH有两种类型:动态调度(DG:Dynamic Grant)的PUSCH和免授权调度(Configured Grant:CG)的PUSCH。当存在PUSCH上行时频资源与SBFD时频资源重合的情况时,可以根据用户设备的FD能力,确定PDSCH在SBFD时频资源中的传输策略。
对于全双工用户设备,由于全双工用户设备可以同时处理上行数据和下行数据,因此,不需要考虑PDSCH与PUSCH的冲突,用户设备可以在发送PUSCH对应的上行数据的同时,接收PDSCH对应的下行数据。
综上可以看出,对于全双工用户设备,上行时频资源上承载的信道类型是PUSCH类型时,若SBFD时频资源中的第一时隙与PUSCH上行时频资源中的第二时隙重合,无论第一时隙中的PRB与第二时隙中的PRB重合,还是第一时隙中的PRB与第二时隙中的PRB不重合,均确定SBFD时频资源为可用时频资源,并在SBFD时频资源上发送PDSCH对应的下行数据。若SBFD时频资源中的第一时隙与PUSCH上行时频资源中的第二时隙不重合,则确定SBFD时频资源为可用时频资源,并在SBFD时频资源发送PDSCH对应的下行数据。
对于半双工用户设备,由于半双工用户设备只能在时频资源上进行发送或者接收,即同一时刻,仅能进行发送或者接收,因此,需要考虑PDSCH与PUSCH的冲突,明确在与不同类型PUSCH重合的SBFD时频资源中如何处理PDSCH。其中,若SBFD时频资源中的第一时隙与PUSCH上行时频资源中的第二时隙不重合,则可以确定SBFD时频资源为可用时频资源,并在SBFD时频资源发送PDSCH对应的下行数据。若SBFD时频资源中的第一时隙与PUSCH上行时频资源中的第二时隙重合,无论第一时隙中的PRB与第二时隙中的PRB重合,还是,第一时隙中的PRB与第二时隙中的PRB不重合,那么:
首先,用于随机接入的PUSCH的优先级高于PDSCH的优先级。其次,动态调度的优先级 高于半静态调度的优先级,比如说,动态调度PDSCH的优先级高于免授权调度PUSCH的优先级,动态调度PUSCH的优先级高于半持续调度PDSCH的优先级。然后,如果调度类型相同,即PUSCH和PDSCH都是动态调度或者半静态调度,则根据PHY信道优先级或MAC信道优先级进行处理。然后,如果PHY信道优先级或MAC信道优先级相同,则根据PUSCH和PDSCH上承载的是初传数据还是重传数据,确定PUSCH的优先级和PDSCH的优先级。
综上可以看出,对于半双工用户设备,PUSCH上行时频资源上承载的信道类型是PUSCH类型时,可以采用如下方式进行处理:
首先,确定PUSCH上行时频资源上承载的PUSCH对应的数据;若该数据为用于随机接入的数据,则确定SBFD时频资源为不可用时频资源。在该情况下,可以通过PUSCH上行时频资源传输PUSCH对应的上行数据,不通过SBFD时频资源传输PDSCH对应的下行数据。其中,若PUSCH对应的数据为:由RAR调度的PUSCH(MSG3)、MAG A之后的PUSCH机会,则数据为用于随机接入的数据。由RAR调度的PUSCH表示类型1的随机接入过程中的消息3(MSG3),PRACH之后的PUSCH机会表示类型2的随机接入过程中紧跟着PRACH的PUSCH。
然后,若PUSCH对应的数据为不用于随机接入的数据,则可以确定PUSCH上行时频资源上承载的PUSCH对应的第一调度类型,并确定SBFD时频资源上承载的PDSCH对应的第二调度类型。其中,若第一调度类型为动态调度,第二调度类型为半静态调度,则可以确定SBFD时频资源为不可用时频资源;在该情况下,可以通过PUSCH上行时频资源传输PUSCH对应的上行数据,不通过SBFD时频资源传输PDSCH对应的下行数据。或者,若第一调度类型为半静态调度,第二调度类型为动态调度,则可以将SBFD时频资源中的所有PRB选取为可用时频资源;在该情况下,可以通过SBFD时频资源传输PDSCH对应的下行数据,不通过PUSCH上行时频资源传输PUSCH对应的上行数据。
然后,若第一调度类型和第二调度类型均为动态调度,或者,第一调度类型和第二调度类型均为半静态调度,则可以确定PUSCH上行时频资源上承载的PUSCH对应的第一优先级,并确定SBFD时频资源上承载的PDSCH对应的第二优先级。第一优先级可以为PHY信道优先级,且第二优先级可以为PHY信道优先级,或者,第一优先级可以为MAC信道优先级,且第二优先级可以为MAC信道优先级。其中,若第一优先级大于第二优先级,则可以确定SBFD时频资源为不可用时频资源;在该情况下,可以通过PUSCH上行时频资源传输PUSCH对应的上行数据,不通过SBFD时频资源传输PDSCH对应的下行数据。或者,若第一优先级小于第二优先级,则可以将SBFD时频资源中的所有PRB选取为可用时频资源;在该情况下,可以通过SBFD时频资源传输PDSCH对应的下行数据,不通过PUSCH上行时频资源传输PUSCH对应的上行数据。
然后,若第一优先级等于第二优先级,那么:若PUSCH上行时频资源上承载的PUSCH对应初传数据,且SBFD时频资源上承载的PDSCH对应重传数据,则可以确定SBFD时频资源为不可用时频资源;在该情况下,可以通过PUSCH上行时频资源传输PUSCH对应的上行数据,不通过SBFD时频资源传输PDSCH对应的下行数据。若PUSCH上行时频资源上承载的PUSCH对应重传数据,且SBFD时频资源上承载的PDSCH对应初传数据,则可以将SBFD时频资源中的所有PRB选取为可用时频资源;在该情况下,可以通过SBFD时频资源传输PDSCH对应的下行数据,不通过PUSCH上行时频资源传输PUSCH对应的上行数据。若PUSCH上行时频资源上承载的PUSCH对应初传数据,且SBFD时频资源上承载的PDSCH对应初传数据,则可以将SBFD时频资源中的所有PRB选取为可用时频资源;在该情况下,可以通过SBFD时频资源传输PDSCH对应的下行数据,不通过PUSCH上行时频资源传输PUSCH对应的上行数据。若PUSCH上行时频资源上承载的PUSCH对应重传数据,且SBFD时频资源上承载的PDSCH对应重传数据,则可以将SBFD时频资源中的所有PRB选取为可用时频资源;在该情况下,可以通过SBFD时频资源传输PDSCH对应的下行数据,不通过PUSCH上行时频资源传输PUSCH对应的上行数据。
在一个例子中,可以通过表1表示上述调度策略,在表1中,示出了PDSCH和不同类型PUSCH在SBFD时频资源冲突时的调度策略。
表1

由以上技术方案可见,可以在SBFD时频资源上传输PDSCH对应的下行数据,从而更加有效的利用SBFD时频资源,提高资源利用率,能够提高网络覆盖和网络容量,同时降低传输时延,如降低下行传输时延。在上述方案中,确定了PDSCH在与PRACH、SRS、PUCCH和PUSCH等冲突时的SBFD时频资源上的调度机制。对于不同能力的用户设备,在SBFD时频资源中调度PDSCH的机制不同。可以明确基站设备和用户设备在SBFD时频资源与其它资源冲突时对PDSCH的调度机制,避免基站设备和用户设备在此情况下产生行为模糊性,保证基站设备和用户设备在全双工模式下都能正常进行PDSCH的传输。
