Description

一种全双工传输的控制方法和用户设备以及基站 技术领域
本发明实施例涉及通信领域,尤其涉及一种全双工传输的控制方法和用户设备以及基站。
背景技术
半双工传输只能够进行信号的单向传输,而全双工传输可以同时进行信号的双向传输,因此全双工传输的信号传输效率很高,从物理层角度来看,全双工传输相比于半双工传输,***吞吐量提高一倍,全双工传输也对介质访问控制(英文全称:Media Access Control,英文简称:MAC)的设计产生革新性的影响,从而使得未来无线通信***能获得更高的吞吐量。
在目前的无线通信***例如无线保真(英文名称:Wireless Fidelity,英文简称:WiFi)***、长期演进(英文全称:Long Term Evolution,英文简称:LTE)***中,主要使用的是半双工传输,半双工传输在相同的时频资源上不能同时进行信号的发送和接收。现有技术中描述了一种在WiFi***中使用的全双工传输方法,可以实现在WiFi***中的同一个信道上同时进行信号的发送和接收,由于WiFi传输可以占据整个信道,不需要频率复用,因此资源分配是固定的,用户设备(英文全称:User Equipment,英文简称:UE)准备好传输信号所需要的时间很少,因此WiFi***可以在检测或接收到一些前导码后立即传输信号,从而实现全双工传输。
但是上述全双工传输的解决方案只适用于WiFi***,而无法适用于需要频率复用的LTE***,因为在LTE***中资源分配需要动态决定,UE需要根据得到的传输块尺寸进行速率匹配,相比于WiFi***,LTE***中UE需要更多的时间用于资源配置。在目前的LTE***中的频分双工(英文全称:Frequency Division Dual,英文简称:FDD)模式下,对于上行调度,基站会提前4毫秒向UE发送上行调度信息,对于下行调度,UE需要提前从基站获取调度相关信息,例如信道状态指示(英文全称:Channel State Information,英文简称:CSI)、缓存大小以及调度资源,下行调度信息和下行数据可以在相同的子帧中传输。这种FDD模式下的调度过程可以应用于LTE***实现全双工传输。例如,n为自然数,在第(n-4)个子帧,基站发送上行调度信息用于在 第n个子帧传输上行信道,同时基站也在第n个子帧传输下行调度信息。这样UE在第n个子帧可以同时进行信号的发送和接收。
对于如上描述的LTE***中实现的全双工传输方案中,当基站在第(n-4)个子帧上发送上行调度信息时,仍然不确定是否在第n个子帧对同一个UE会同时存在下行传输,而全双工传输和半双工传输中对上行传输会有不同的传输功率要求,这样基站就不确定在全双工传输中第n个子帧的上行传输是否会面临自干扰取消的问题。因此,第n个子帧的上行信道的功率控制就无法被正确设置,因不精确的功率控制会导致强烈的自干扰,这种自干扰很难被取消,从而使得下行数据不可检测,因此现有技术中LTE***中实现的全双工传输存在***增益很低的问题。
发明内容
本发明实施例提供了一种全双工传输的控制方法和用户设备以及基站,适用于LTE***以及WiFi***中实现全双工传输,并且可以实现在全双工传输时对上行信道的功率控制,提高全双工传输的***增益。

以下分别进行详细说明。
本发明全双工传输的控制方法的一个实施例,可应用于用户设备侧实现在全双工传输中的上行功率控制场景中,请参阅图1所示,本发明一个实施例提供的全双工传输的控制方法,可以包括:
101、用户设备获取第一时间资源单位。
在本发明实施例中以用户设备对第一时间资源单位的全双工传输控制为例,用户设备首先获取第一时间资源单位,对该第一时间资源单位进行检测,检测是否可以从第一时间资源单位中获取到包括指示全双工传输的调度授权信息,具体的,可实现的方式是,用户设备可以检测第一时间资源单位中的时间资源单位头,通过在第一时间资源单位的时间资源单位头中特定的字段信息或者指示位来确定是否包括指示全双工传输的调度授权信息,又如用户设备可以检测第一时间资源单位以外的其他时间资源单位,通过其他时间资源单位对第一时间资源单位的指示信息来确定第一时间资源单位中是否包括指示全双工传输的调度授权信息,又如用户设备可以检测基站发送的信令,用户设备通过基站发送的信令来确定第一时间资源单位中是否包括指示全双工传输的调度授权信息,又如用户设备还可以通过预定义的配置信息来确定第一时间资源单位中是否包括指示全双工传输的调度授权信息。对于包括指示全双工传输的调度授权信息的第一时间资源单位,用户设备可以在上述第一时间资源单位上进行全双工传输,对于不包括指示全双工传输的调度授权信息的第一时间资源单位,用户设备在上述第一时间资源单位上可以进行半双工传输,而不再进行全双工传输。在检测到包括指示全双工传输的调度授权信息的第一时间资源单位之后,用户设备执行后续步骤102。
在本发明的一些实施例中,步骤101中用户设备获取到的时间资源单位是第一时间资源单位,其中,时间资源单位具体可以包括:子帧、帧、时隙、正交频分复用(英文全称:Orthogonal Frequency Division Multiplexing,英文简称:OFDM)符号。即在本发明的一些实施例中描述的一个时间资源单位可以具体为一个子帧,例如,后续实施例中描述的第一时间资源单位具体为第一子帧,第二时间资源单位具体为第二子帧,第三时间资源单位具体可以为第三子帧,第四时间资源单位具体为第四子帧,第五时间资源单位具体可以为第五子帧。在本发明的另一些实施例中描述的一个时间资源单位具体可以为一个帧(即无线帧),例如,后续实施例中描述的第一时间资源单位具体为第一帧,第二时间资源单位具体为第二帧,第三时间资源单位具体可以为第三帧,第四时间资源单位具体为第四帧,第五时间资源单位具体可以为第五帧。或者,一个时间资源单位具体可以为一个时隙,或者一个时间资源单位具体可以为一个OFDM符号。需要说明的是,时间资源单位具体可根据应用场景的需要来选 取为子帧、帧、时隙、OFDM符号,具体不做限定,在本发明实施例中,子帧、帧、时隙、OFDM符号之间的关系在一种可实现的方式中,1个帧=10个子帧=10毫秒(ms)=20个时隙=140个OFDM符号。
在本发明的一些实施例中,步骤101用户设备获取第一时间资源单位,具体可以包括如下步骤:
A1、用户设备在提前于第一时间资源单位的第三时间资源单位上检测是否存在指示在第一时间资源单位或第二时间资源单位上进行传输的上行调度信息,以及在第一时间资源单位或提前于第一时间资源单位的第四时间资源单位上检测是否存在指示在第一时间资源单位或第二时间资源单位上进行传输的下行调度信息,第三时间资源单位和第四时间资源单位是两个不同的时间资源单位;
A2、若在第三时间资源单位上检测到上行调度信息,且第一时间资源单位和第三时间资源单位之间相差的时间资源单位个数满足预置的差值,且在第一时间资源单位或第四时间资源单位上检测到下行调度信息,则确定第一时间资源单位中包括指示全双工传输的调度授权信息;
A3、若在第三时间资源单位上未检测到上行调度信息,或第一时间资源单位和第三时间资源单位之间相差的时间资源单位个数不满足预置的差值,或在第一时间资源单位或第四时间资源单位上未检测到下行调度信息,则确定第一时间资源单位中没有包括指示全双工传输的调度授权信息。
在上述步骤A1至步骤A3的实现方式中,第三时间资源单位为提前于第一时间资源单位的时间资源单位,第四时间资源单位为提前于第一时间资源单位的时间资源单位,并且第三时间资源单位和第四时间资源单位是两个不同的时间资源单位,用户设备在第一时间资源单位之前的第三时间资源单位上检测第三时间资源单位中是否存在上行调度信息,该上行调度信息用于指示在第一时间资源单位或第二时间资源单位上进行传输上行数据信息,例如用户设备检测第三时间资源单位的时间资源单位头来获取是否存在上行调度信息,由于上行调度在信号传输之前需要占用一定的准备时间,因此若需要在第一时间资源单位中进行上行传输,就需要基站在第一时间资源单位之前的一个时间资源单位中发送上行调度信息,本发明实施例中,用户设备检测在第一时间资源单位之前的每个时间资源单位,例如用户设备可以检测在第一时间资源单位之前的 第三时间资源单位,用户设备判断第三时间资源单位中是否存在上行调度信息,若用户设备在第三时间资源单位中检测到基站发送的上行调度信息,则说明用户设备可以在第三时间资源单位之后的某个时间资源单位上进行上行调度传输。
另外,第四时间资源单位为提前于第一时间资源单位的时间资源单位,该第四时间资源单位和第三时间资源单位都在第一时间资源单位之前,但是第四时间资源单位和第三时间资源单位是两个不同的时间资源单位,用户设备在第一时间资源单位或第四时间资源单位上检测是否存在指示在第一时间资源单位或第二时间资源单位上进行传输的下行调度信息,也就是说,用户设备可以判断第一时间资源单位是否包括指示全双工传输的调度授权信息时,用户设备对下行调度信息的检测可以是在本时间资源单位(即第一时间资源单位),也可以在本时间资源单位之前的一个时间资源单位(例如是第四时间资源单位)。该下行调度信息用于指示在第一时间资源单位或第二时间资源单位上进行传输下行数据信息,例如用户设备检测第四时间资源单位的时间资源单位头来获取是否存在下行调度信息,若用户设备在第四时间资源单位中检测到基站发送的下行调度信息,则说明用户设备可以在第四时间资源单位之后的某个时间资源单位上进行下行调度传输。
在上述步骤A1至步骤A3的实现方式中,若满足如下三个条件就说明第一时间资源单位中包括了指示全双工传输的调度授权信息,该三个条件为:1)在第三时间资源单位上检测到了上行调度信息,2)第一时间资源单位和第三时间资源单位之间相差的时间资源单位个数为预置的差值,例如该差值为4个时间资源单位,也就是说,若第一时间资源单位为第n个时间资源单位,n为自然数,若在第n-4个时间资源单位上检测到了上行调度信息,此时第三时间资源单位为第n-4个时间资源单位,第一时间资源单位和第三时间资源单位之间相差的时间资源单位个数为4。3)、第一时间资源单位或第四时间资源单位上检测到了下行调度信息。在同时满足如上的3个条件时,用户设备可以确定第n个时间资源单位包括指示全双工传输的调度授权信息。若不能同时满足上述条件1)、条件2)和条件3),则说明第一时间资源单位中没有包括指示全双工传输的调度授权信息。例如,在第三时间资源单位上未检测到上行调度信息,或者即使在第三时间资源单位上检测到了上行调度信息,但是第一时间 资源单位和第三时间资源单位之间相差的时间资源单位个数不满足预置的差值,或者在第一时间资源单位或第四时间资源单位上没有检测到下行调度信息,在上述情况下都说明第一时间资源单位中不包括指示全双工传输的调度授权信息。
通过步骤A1对于第三时间资源单位的检测,以及对第一时间资源单位或第四时间资源单位的检测可知,若在第三时间资源单位上检测到上行调度信息,且第一时间资源单位和第三时间资源单位之间相差的时间资源单位个数满足预置的差值,且在第一时间资源单位或第四时间资源单位上检测到下行调度信息,在本发明的一些实施例中,步骤A2用户设备在提前于第一时间资源单位的第三时间资源单位上检测是否存在指示在第一时间资源单位或第二时间资源单位上进行传输的上行调度信息之后,本发明实施例提供的全双工传输的控制方法,还可以包括如下步骤:
A4、若下行调度信息中包括的功率偏移为一个预置的特殊定义的偏移值,用户设备根据下行调度信息中包括的功率偏移取消第三时间资源单位中的上行调度信息指示的在第一时间资源单位或第二时间资源单位上进行的上行数据信息传输。
在步骤A4中,下行调度信息为在第一时间资源单位或者第四时间资源单位中传输的信息,若基站在第三时间资源单位中的上行调度信息指示了在第一时间资源单位或第二时间资源单位的上行数据信息传输,在基站需要取消这个上行数据信息传输时,基站可以在该下行调度信息中包括的功率偏移的取值为一个预置的特殊定义的偏移值,使用户设备在检测到这个特殊含义的偏移值之后取消第三时间资源单位中的上行调度信息指示的上行数据传输。则用户设备从第一时间资源单位或第四时间资源单位中检测到功率偏移之后,用户设备发现该功率偏移为一个预置的特殊定义的偏移值,用户设备会取消在第一时间资源单位或者第二时间资源单位中的上行数据信息传输。举例说明,用户设备可以根据功率偏移的取值为一个特殊定义的功率偏移值时,该特殊定义的功率偏移值被用来阻止相同时间资源单位中与下行传输同时进行的上行传输。
在本发明的一些实施例中,步骤101用户设备获取第一时间资源单位,具体可以包括如下步骤:
B1、用户设备在第一时间资源单位上检测是否有对应于提前于第一时间 资源单位的第五时间资源单位的下行数据信息传输的上行反馈信息,并在第一时间资源单位或提前于第一时间资源单位的第四时间资源单位上检测是否存在指示在第一时间资源单位或第二时间资源单位上进行传输的下行调度信息;
B2、若在第一时间资源单位上检测到对应于第五时间资源单位的下行数据信息传输的上行反馈信息,且第一时间资源单位和第五时间资源单位之间相差的时间资源单位个数满足预置的差值,且在第一时间资源单位或第四时间资源单位上检测到下行调度信息,则确定第一时间资源单位中包括指示全双工传输的调度信息,第四时间资源单位和第五时间资源单位是两个不同的时间资源单位;
B3、若在第一时间资源单位上未检测到上行反馈信息,或第一时间资源单位和第五时间资源单位之间相差的时间资源单位个数不满足预置的差值,或在第一时间资源单位或第四时间资源单位上未检测到下行调度信息,则确定第一时间资源单位中没有包括全双工传输的信息。
在上述步骤B1至步骤B3的实现方式中,第五时间资源单位为提前于第一时间资源单位的时间资源单位,用户设备在第一时间资源单位上检测是否存在上行反馈信息,该上行反馈信息是对应于在第五时间资源单位上传输的下行数据信息的反馈信息,例如用户设备检测第一时间资源单位的时间资源单位头来获取是否存在上行反馈信息,该上行反馈信息可以是确认信息(英文全称:Acknowledgement,英文简称:ACK)或者否认信息(英文全称:Negative Acknowledgement,英文简称:NACK),具体取决于用户设备在第五时间资源单位上接收下行数据信息的接收情况。本发明实施例中,用户设备检测在第一时间资源单位,用户设备判断第一时间资源单位中是否存在上行反馈信息,若用户设备在第一时间资源单位中检测到上行反馈信息,则说明用户设备可以在第一时间资源单位上进行上行调度传输。
另外,第四时间资源单位为提前于第一时间资源单位的时间资源单位,该第四时间资源单位和第五时间资源单位都在第一时间资源单位之前,但是第四时间资源单位和第五时间资源单位是两个不同的时间资源单位,用户设备在第一时间资源单位或第四时间资源单位上检测是否存在指示在第一时间资源单位或第二时间资源单位上进行传输的下行调度信息,也就是说,用户设备可以判断第一时间资源单位是否包括指示全双工传输的调度授权信息时,用户设备 对下行调度信息的检测可以是在本时间资源单位(即第一时间资源单位),也可以在本时间资源单位之前的一个时间资源单位(例如是第四时间资源单位)。该下行调度信息用于指示在第一时间资源单位或第二时间资源单位上进行传输下行数据信息,例如用户设备检测第四时间资源单位的时间资源单位头来获取是否存在下行调度信息,若用户设备在第四时间资源单位中检测到基站发送的下行调度信息,则说明用户设备可以在第四时间资源单位之后的某个时间资源单位上进行下行调度传输。
在上述步骤B1至步骤B3的实现方式中,若满足如下三个条件就说明第一时间资源单位中包括了指示全双工传输的调度授权信息,该三个条件为:1)在第一时间资源单位上检测到了上行反馈信息,2)第一时间资源单位和第五时间资源单位之间相差的时间资源单位个数为预置的差值,例如该差值为2个时间资源单位,也就是说,若第一时间资源单位为第n个时间资源单位,n为自然数,若在第n-2个时间资源单位上检测到了下行数据信息,在第n个时间资源单位上检测到了对应于该下行数据信息的上行反馈信息,此时第五时间资源单位为第n-2个时间资源单位,第一时间资源单位和第五时间资源单位之间相差的时间资源单位个数为2。3)、第一时间资源单位或第四时间资源单位上检测到了下行调度信息。在同时满足如上的3个条件时,用户设备可以确定第n个时间资源单位包括指示全双工传输的调度授权信息。若不能同时满足上述条件1)、条件2)和条件3),则说明第一时间资源单位中没有包括指示全双工传输的调度授权信息。例如,在第一时间资源单位上未检测到上行反馈信息,或者第一时间资源单位和第五时间资源单位之间相差的时间资源单位个数不满足预置的差值,或者在第一时间资源单位或第四时间资源单位上没有检测到下行调度信息,在上述情况下都说明第一时间资源单位中不包括指示全双工传输的调度授权信息。
在本发明的一些实施例中,步骤101用户设备获取第一时间资源单位,具体可以包括如下步骤:
C1、用户设备在第一时间资源单位上检测是否存在上行调度信息和下行调度信息;
C2、若在第一时间资源单位上同时检测到上行调度信息和下行调度信息,则确定第一时间资源单位中包括指示全双工传输的调度授权信息;
C3、若在第一时间资源单位上至多检测到上行调度信息和下行调度信息中的一个调度信息,则确定第一时间资源单位中没有包括指示全双工传输的调度授权信息。
在上述步骤C1至C3的实现方式中,用户设备只需要检测第一时间资源单位即可,具体的,用户设备需要检测第一时间资源单位中是否同时包括上行调度信息和下行调度信息,在步骤C1至C3的实现方式下,全双工传输可以同时调度上下行的传输资源同时实现信号的发送和接收,例如,在物理下行控制信道(英文全称:Physical Downlink Control Channel,英文简称:PDCCH)中通过同时传输的上下行资源分配给用户设备实现全双工传输,在这种方式下,可以通过一个单一的调度授权信息检测出第一时间资源单位是否可用于全双工传输。通过对第一时间资源单位自身的检测来确定第一时间资源单位是否包括上述调度授权信息,例如,用户设备检测第一时间资源单位中是否同时包括上下行调度信息,若在第一时间资源单位中同时检测到了上行调度信息和下行调度信息,则用户设备可以确定第一时间资源单位可以用于全双工传输,若在第一时间资源单位中最多只检测到上行调度信息和下行调度信息中的其中一个,则用户设备确定第一时间资源单位不可以用于全双工传输,即在第一时间资源单位中不包括用于指示全双工传输的调度授权信息。
在前述描述的实施例中,上行调度信息可以为上行授权信息,下行调度信息可以是下行授权信息,其中,上行授权信息和下行授权信息可以是。上行授权信息包括用户设备可以在哪个时间哪个载波上(例如物理资源块)上传输数据,以及采用的MCS,它是PDCCH的内容之一。下行授权信息为基站在每个传输时间间隔(英文全称:Transmission Time Interval,英文简称:TTI)(即一个时间资源单位)动态的给用户设备分配资源,包括物理资源块以及采用的MCS,它是PDCCH的内容之一。另外上行调度信息和下行调度信息也可以预先配置的其它控制信息,只要用户设备侧可以检测上行调度信息和下行调度信息携带的指示内容即可。
102、若从第一时间资源单位中获取到包括指示全双工传输的调度授权信息,用户设备根据用户设备获取到的功率偏移对用于半双工传输的第一上行传输功率进行修正,得到用于全双工传输的第二上行传输功率。
在本发明实施例中,若通过步骤101获取到第一时间资源单位,从第一时 间资源单位中获取到了包括指示全双工传输的调度授权信息,则用户设备确定第一时间资源单位可以用于进行全双工传输,在第一时间资源单位需要进行全双工传输的情况下,全双工传输中上行传输的传输功率可以通过用户设备获取到的功率偏移对用于半双工传输的第一上行传输功率的修正得到,具体的,用户设备可以使用预定义的功率偏移对用于半双工传输的第一上行传输功率进行修正,得到用于全双工传输的第二上行传输功率,或者用户设备可以使用从第一时间资源单位或者预先配置的其它时间资源单位中检测到功率偏移。也就是说,用户设备获取到的功率偏移是用户设备预先定义的功率偏移或者用户设备通过基站发送的调度授权信息获取到的功率偏移,该功率偏移为在全双工传输下对用于半双工传输的第一上行传输功率进行修改的偏移功率值。另外,在本发明实施例中,第一上行传输功率为在不进行下行传输只进行上行传输时用户设备使用的上行传输功率,即该第一上行传输功率是用户设备获取到的用于半双工传输的上行传输功率。
在本发明的一些实施例中,在前述执行步骤A1至A3的实现方式或者执行步骤B1至B3的实现方式中,步骤102用户设备根据用户设备获取到的功率偏移对用于半双工传输的第一上行传输功率进行修正之前,本发明实施例提供的全双工传输的控制方法,还可以包括如下步骤:
D1、用户设备从第三时间资源单位中的上行调度信息中获取到用于半双工传输的第一上行传输功率,或,用户设备从第五时间资源单位中获取到用于半双工传输第一上行传输功率;
D2、用户设备通过预定义的方式获取到功率偏移,或从第一时间资源单位中或第四时间资源单位中获取到功率偏移。
其中,步骤D1中描述了用户设备获取第一上行传输功率的方式,用户设备可以从提前于第一时间资源单位的一个时间资源单位中获取到第一上行传输功率,例如从前述的第三时间资源单位或者第五时间资源单位中获取到。在步骤102中用户设备计算第二上行传输功率时还需要使用到功率偏移,步骤D2中描述了用户设备获取功率偏移的方式,用户设备可以通过预定义的方式获取到,另外基站还可以在第一时间资源单位或第四时间资源单位中发送功率偏移,用户设备还可以从第一时间资源单位或第四时间资源单位中获取到功率偏移。
在本发明的一些实施例中,功率偏移由用户设备通过预定义的方式得到,或者功率偏移由用户设备从第一时间资源单位的下行调度信息中检测得到,或者功率偏移由用户设备从配置的多个时间资源单位中的每个时间资源单位中的调度授权信息中检测得到,配置的多个时间资源单位为所有能检测到全双工传输的授权时间资源单位集合的子集。其中,配置的多个时间资源单位可以是基站指定的多个时间资源单位的集合,则配置的多个时间资源单位为所有能够检测到全双工传输的授权时间资源单位集合的子集,也就是说,配置的多个时间资源单位可以是一个时间资源单位集合,该时间资源单位集合是能够检测到全双工传输的授权时间资源单位集合的一个子集,基站不需要在每个时间资源单位都携带功率偏移,这会增加***开销,而是基站会预先配置在上述时间资源单位集合中的每个时间资源单位上携带功率偏移,用户设备只需要从基站配置的这个时间资源单位集合中的每个时间资源单位中检测功率偏移,而在时间资源单位集合以外用户设备不做功率偏移的检测。
因此,用户设备只检测时间资源单位集合中的每个时间资源单位是否携带有功率偏移,而对于时间资源单位集合以外的时间资源单位则不检测是否携带有功率偏移。因此,本发明实施例中,用户设备只对时间资源单位集合中的所有时间资源单位进行功率偏移的检测,而对于时间资源单位集合以外的时间资源单位,用户设备不需要进行功率偏移的检测,因此用户设备检测是否携带有功率偏移只会针对时间资源单位集合内的时间资源单位,不会产生过多的负荷。
在上述实现场景下,步骤102用户设备根据用户设备获取到的功率偏移对用于半双工传输的第一上行传输功率进行修正之前,本发明实施例提供的全双工传输的控制方法还可以包括如下步骤:
若功率偏移由用户设备通过预定义的方式得到,用户设备通过从第一时间资源单位或提前于第一时间资源单位的一个时间资源单位的调度授权信息中检测到对应的触发信令时,触发功率偏移生效。
在前述描述中若功率偏移是由用户设备通过预定义的方式得到,那么用户设备还需要基站发送的触发信令来触发功率偏移生效,该触发信令被基站携带在第一时间资源单位或者提前于第一时间资源单位的一个时间资源单位的调度授权信息中,用户设备获取到该调度授权信息对应的触发信令时就可以触发 功率偏移生效。
进一步的,在本发明的一些实施例中,功率偏移由用户设备通过预定义的方式得到,具体包括如下步骤:
用户设备接收基站发送的广播信令或者专有信令;
用户设备通过广播信令或者专有信令获取到功率偏移。
其中,功率偏移的预定义方式可以是基站通过广播信令或者专有信令来发送功率偏移,用户设备通过广播信令或者专有信令接收到功率偏移之后,用户设备就可以保存该功率偏移,用于在接收对该功率偏移的触发信令时触发该功率偏移生效,其中,基站发送的专有信令可以是预置的无线资源控制信令,另外专有信令也可是基站和用户设备公知的其它信令。
进一步的,在本发明的一些实施例中,功率偏移由用户设备从第一时间资源单位的调度授权信息中检测得到,或者功率偏移由用户设备从配置的多个时间资源单位中的每个时间资源单位中的调度授权信息中检测得到,具体可以包括如下步骤:
用户设备从调度授权信息中新增加的信息中检测到功率偏移;
或者,用户设备从调度授权信息中重新定义的原有信息中检测到功率偏移。
也就是说,在功率偏移由用户设备检测得到的情况下,基站可以通过如下方式来设置功率偏移,以使用户设备通过从调度授权信息中检测出功率偏移,例如,基站可以在调度授权信息中新增加信息,在新增加的信息中携带功率偏移,则用户设备可以检测调度授权信息中新增加的信息,又如,基站还可以对调度授权信息中的原有信息进行重新定义,则重新定义后的原有信息就可以用于携带功率偏移,因此用户设备可以检测调度授权信息中重新定义的原有信息。
在本发明的一些实施例中,步骤102用户设备根据用户设备获取到的功率偏移对用于半双工传输的第一上行传输功率进行修正,得到用于全双工传输的第二上行传输功率,具体可以包括如下步骤:
用户设备通过如下方式计算用于全双工传输的第二上行传输功率:
PFD=PHD-Poffset
其中,PFD为第二上行传输功率,PHD为第一上行传输功率,Poffset为用户设 备获取到的功率偏移。
也就是说,用户设备可以使用功率偏移对第一上行传输功率进行运算,从第一上行传输功率中减去功率偏移,从而可以得到第二行上传输功率,需要说明的是,在本发明的其它实施例中,根据功率偏移对第一上行传输功率的修正还可以采用其它方式,例如根据从第一上行传输功率中减去功率偏移后再乘以一个预置的比例值,或者从第一上行传输功率中减去功率偏移后再减去一个预置的补偿值,都可以计算出用于半双工传输的第二上行传输功率,具体实现可以结合应用场景的需要,此处仅作举例说明。
具体的,以物理上行共享信道(英文全称:Physical Uplink Shared Channel,英文简称:PUSCH)为例,步骤102具体可以包括如下步骤:
通过如下方式计算用于全双工传输的第二上行传输功率:
PFD(n)=PPUSCH(n)-Poffset(n);
其中,第n个时间资源单位为第一时间资源单位,PFD(n)为第二上行传输功率,PPUSCH(n)为PUSCH进行半双工传输的第一上行传输功率,Poffset(n)为用户设备获取到的功率偏移。
具体的,以物理上行控制信道(英文全称:Physical Uplink Control Channel,英文简称:PUCCH)为例,步骤102具体可以包括如下步骤:
通过如下方式计算用于全双工传输的第二上行传输功率:
PFD(n)=PPUCCH(n)-Poffset(n);
其中,第n个时间资源单位为第一时间资源单位,PFD(n)为第二上行传输功率,PPUCCH(n)为PUCCH进行半双工传输的第一上行传输功率,Poffset(n)为用户设备获取到的功率偏移。
在本发明的一些实施例中,步骤102用户设备根据用户设备获取到的功率偏移对用于半双工传输的第一上行传输功率进行修正之后,本发明实施例提供的全双工传输的控制方法,还可以包括如下步骤:
E1、用户设备获取与功率偏移匹配的调制与编码策略(英文全称Modulation and Coding Scheme,英文简称:MCS)偏移;
E2、用户设备根据MCS偏移对用于半双工传输的第一MCS索引进行修正,得到用于全双工传输的第二MCS索引。
其中,本发明实施例中,功率偏移可以和MCS偏移相匹配,即通过一个 功率偏移可以获取到对应于该功率偏移的MCS偏移,MCS可以代表上行信道的质量,根据上行信道采用的MCS可以确定各个控制部分不同的编码速率,也就是决定了各个部分所占用的资源块数目。基站可以将MCS偏移通过显性信令通知给用户设备,用户设备可以通过该显性信令获取到功率偏移,或者用户设备可以通过MCS偏移与功率偏移的匹配关系获取到MCS偏移,用户设备获取到MCS偏移之后,可以根据MCS偏移对第一MCS索引进行修正,得到可用于全双工传输的第二MCS索引。
在本发明的一些实施例中,步骤E1用户设备获取与功率偏移匹配的调制与编码策略MCS偏移,具体可以包括如下步骤:
E11、用户设备通过广播信令或者专有信令接收到MCS偏移;
或者,E12、用户设备通过预定义的功率偏移和MCS偏移的相互匹配关系获取到MCS偏移。
其中,用户设备获取MCS偏移的方式可以是通过广播信令或者专有信令,该广播信令或者专有信令由基站来配置,当基站使用广播信令或者专有信令来发送MCS偏移时,用户设备可以获取到MCS偏移,例如基站配置的专有信令可以是无线资源控制信令。另外,功率偏移和MCS偏移之间有相互匹配关系,可以根据该预定义的相互匹配关系获取到MCS偏移。举例说明,与功率偏移匹配的MCS偏移可以通过显性信令指示或者隐形信令指示。显性信令指示为通知功率偏移时,明确通过额外的比特专门指示MCS偏移。隐性信令指示为通知功率偏移时,不需要通过额外的比特专门指示MCS偏移,而是通过预先定义的相互匹配来获取到MCS偏移。
具体的,以PUSCH为例,步骤E2具体可以包括如下步骤:
通过如下方式计算用于全双工传输的第二MCS索引:
MCSFD(n)=MCSPUSCH(n)-MCSoffset(n);
其中,第n个时间资源单位为第一时间资源单位,MCSFD(n)为第二MCS索引,MCSPUSCH(n)为PUCCH进行半双工传输的第一MCS索引,MCSoffset(n)为用户设备获取到的MCS偏移。
也就是说,用户设备可以使用MCS偏移对第一MCS索引进行运算,从第一MCS索引中减去MCS偏移,从而可以得到第二MCS索引,需要说明的是,在本发明的其它实施例中,根据MCS偏移对第一MCS索引的修正还可 以采用其它方式,例如根据从第一MCS索引中减去MCS偏移后再乘以一个预置的比例值,或者从第一MCS索引中减去MCS偏移后再减去一个预置的补偿值,都可以计算出用于半双工传输的第二MCS索引,具体实现可以结合应用场景的需要,此处仅作举例说明。
103、用户设备按照第二上行传输功率在第一时间资源单位或第二时间资源单位上传输上行信号,第二时间资源单位为在时间上处于第一时间资源单位之后的时间资源单位。
在本发明实施例中,用户设备从第一时间资源单位中获取到包括指示全双工传输的调度授权信息,用户设备获取到用于全双工传输的第二上行传输功率,则第二上行传输功率可以用于在第一时间资源单位或者第一时间资源单位之后的第二时间资源单位传输上行信号。本发明实施例中在第一时间资源单位或者第二时间资源单位进行全双工传输时,可以按照步骤102中确定出的第二上行传输功率进行上行信号的传输,从而使得上行信道的功率控制可以被正确设置,精确的功率控制可以避免自干扰,使得下行数据可以被正常检测,提高LTE***和WiFi***中实现的全双工传输的***增益。
在本发明的一些实施例中,在前述执行步骤A1至A3、步骤B1至B3的实现场景下,步骤103中的上行信号为对第三时间资源单位中的上行调度信息指示在第一时间资源单位或第二时间资源单位上进行传输的上行数据信息,或者,上行信号为第五时间资源单位中的下行数据信息对应的第一时间资源单位的上行反馈信息,其中,上行反馈信息具体可以为确认信息或者否认信息。举例说明如下,以PDSCH为例,用户设备在第五时间资源单位上检测到下行数据信息,根据该下行数据信息,用户设备需要在第一时间资源单位上反馈确认信息或者否认信息,用户设备在反馈确认信息或者否认信息之前,用户设备还可以在第一时间资源单位上检测下行调度信息,若在第一时间资源单位上还检测到下行调度信息,则说明用户设备可以在第一时间资源单位上进行全双工传输,用户设备将确认信息或者否认信息可使用的传输功率调整为前述的第二上行传输功率。
通过前述实施例对本发明的描述可知,用户设备首先获取第一时间资源单位,若从第一时间资源单位中获取到包括指示全双工传输的调度授权信息,用户设备接下来根据用户设备获取到的功率偏移对用于半双工传输的第一上行 传输功率进行修正,得到用于全双工传输的第二上行传输功率,用户设备最后按照第二上行传输功率在第一时间资源单位或第二时间资源单位上传输上行信号,第二时间资源单位为在第一时间资源单位之后的时间资源单位。本发明实施例中用户设备可以通过预置的功率偏移确定出第二上行传输功率,因此上行信道的功率控制可以按照用户设备确定进行全双工传输时对第一上行传输功率进行修正得到的第二上行传输功率进行正确设置,因此可以实现精确的功率控制,从而可以避免自干扰,使得下行数据可以被正常检测,提高无线通信***中全双工传输的***增益,本发明提供的方法可以用于LTE***和WiFi***。
前述实施例从用户设备侧介绍本发明提供的全双工传输的控制方法,接下来从基站侧介绍本发明提供的全双工传输的控制方法,请参阅如图2所示,本发明实施例提供的全双工传输的控制方法可以包括如下步骤:
201、基站确定是否在第一时间资源单位中指示用户设备进行全双工传输,得到确定结果。
在本发明实施例中以基站对第一时间资源单位的全双工传输控制为例,基站确定需要进行控制处理的第一时间资源单位,确定是否在第一时间资源单位中指示用户设备进行全双工传输,得到确定结果,该确定结果有两种情况:一种是确定结果为可以在第一时间资源单位中指示用户设备进行全双工传输,在这种情况下可以触发执行步骤202,另一种是确定结果为不可以在第一时间资源单位中指示用户设备进行全双工传输,在这种情况下基站不会在第一子帧指示用户设备进行全双工传输。具体的,可实现的方式是,基站可以通过在第一时间资源单位中的具体传输来确定是否在第一时间资源单位中指示用户设备进行全双工传输,基站可以通过在第一时间资源单位之前的其它时间资源单位中的具体传输来确定是否在第一时间资源单位中指示用户设备进行全双工传输。基站确定是否在第一时间资源单位中指示用户设备进行全双工传输之后,用户设备可以得到基站指示的是否可以进行全双工传输,用户设备进而可以确定是否在第一时间资源单位或第二时间资源单位上进行全双工传输,需要说明的是,若步骤201中基站确定用户设备是否可以在第二时间资源单位中进行全双工传输,则用户设备可以得到基站指示的是否可以进行全双工传输,用户设备进而可以确定是否在第二时间资源单位上进行全双工传输。
在本发明的一些实施例中,步骤201中基站获取到的时间资源单位是第一时间资源单位,其中,时间资源单位具体可以包括:子帧、帧、时隙、OFDM符号。即在本发明的一些实施例中描述的一个时间资源单位可以具体为一个子帧,例如,后续实施例中描述的第一时间资源单位具体为第一子帧,第二时间资源单位具体为第二子帧,第三时间资源单位具体可以为第三子帧,第四时间资源单位具体为第四子帧,第五时间资源单位具体可以为第五子帧。在本发明的另一些实施例中描述的一个时间资源单位具体可以为一个帧(即无线帧),例如,后续实施例中描述的第一时间资源单位具体为第一帧,第二时间资源单位具体为第二帧,第三时间资源单位具体可以为第三帧,第四时间资源单位具体为第四帧,第五时间资源单位具体可以为第五帧。或者,一个时间资源单位具体可以为一个时隙,或者一个时间资源单位具体可以为一个OFDM符号。需要说明的是,时间资源单位具体可根据应用场景的需要来选取为子帧、帧、时隙、OFDM符号,具体不做限定。
在本发明的一些实施例中,步骤201基站确定是否在第一时间资源单位中指示用户设备进行全双工传输,具体可以包括如下步骤:
F1、若基站在提前于第一时间资源单位的第三时间资源单位上传输指示在第一时间资源单位或第二时间资源单位上进行传输的上行调度信息,且基站在第一时间资源单位或提前于第一时间资源单位的第四时间资源单位上传输指示在第一时间资源单位或第二时间资源单位上进行传输的下行调度信息,则基站确定用户设备可以在第一时间资源单位中进行全双工传输,第三时间资源单位和第四时间资源单位是两个不同的时间资源单位;
F2、若基站未在第三时间资源单位上传输上行调度信息,或基站确定第一时间资源单位和第三时间资源单位之间相差的时间资源单位个数不满足预置的差值,或基站在第一时间资源单位或第四时间资源单位上未检测到下行调度信息,则基站确定用户设备不可以在第一时间资源单位中进行全双工传输。
其中,第三时间资源单位为提前于第一时间资源单位的时间资源单位,第四时间资源单位为提前于第一时间资源单位的时间资源单位,并且第三时间资源单位和第四时间资源单位是两个不同的时间资源单位,基站在第一时间资源单位之前的第三时间资源单位上传输上行调度信息,该上行调度信息用于指示在第一时间资源单位或第二时间资源单位上进行传输上行数据信息,第四时间 资源单位为提前于第一时间资源单位的时间资源单位,该第四时间资源单位和第三时间资源单位都在第一时间资源单位之前,但是第四时间资源单位和第三时间资源单位是两个不同的时间资源单位,基站在第一时间资源单位或第四时间资源单位上传输下行调度信息,在满足上述条件时,表示基站确认可以在第一时间资源单位中指示用户设备进行全双工传输。
进一步的,在本发明的一些实施例中,下行调度信息,包括:一个预先配置的特殊定义的偏移值,由用户设备根据下行调度信息中包括的功率偏移取消第三时间资源单位上的上行调度信息指示的在第一时间资源单位或第二时间资源单位上进行的上行数据信息传输。
其中,下行调度信息为在第一时间资源单位或者第四时间资源单位中传输的信息,若基站在第三时间资源单位中的上行调度信息指示了在第一时间资源单位或第二时间资源单位的上行数据信息传输,在基站需要取消这个上行数据信息传输时,基站可以在该下行调度信息中包括的功率偏移的取值为一个预置的特殊定义的偏移值,使用户设备在检测到这个特殊含义的偏移值之后取消第三时间资源单位中的上行调度信息指示的上行数据传输。则用户设备从第一时间资源单位或第四时间资源单位中检测到功率偏移之后,用户设备发现该功率偏移为一个预置的特殊定义的偏移值,用户设备会取消在第一时间资源单位或者第二时间资源单位中的上行数据信息传输。举例说明,用户设备可以根据功率偏移的取值为一个特殊定义的功率偏移值时,该特殊定义的功率偏移值被用来阻止相同时间资源单位中与下行传输同时进行的上行传输。
在本发明的一些实施例中,步骤201基站确定是否在第一时间资源单位中指示用户设备进行全双工传输,具体可以包括如下步骤:
G1、若基站在第一时间资源单位上传输对应于提前于第一时间资源单位的第五时间资源单位的下行数据信息传输的上行反馈信息,且基站在第一时间资源单位或提前于第一时间资源单位的第四时间资源单位上传输指示在第一时间资源单位或第二时间资源单位上进行传输的下行调度信息,则基站确定用户设备可以在第一时间资源单位中进行全双工传输,第四时间资源单位和第五时间资源单位是两个不同的时间资源单位;
G2、若基站未在第一时间资源单位上传输上行反馈信息,或基站确定第一时间资源单位和第五时间资源单位之间相差的时间资源单位个数不满足预 置的差值,或基站在第一时间资源单位或第四时间资源单位上未检测到下行调度信息,则基站确定用户设备可以在第一时间资源单位中进行全双工传输。
其中,第五时间资源单位为提前于第一时间资源单位的时间资源单位,第四时间资源单位为提前于第一时间资源单位的时间资源单位,并且第五时间资源单位和第四时间资源单位是两个不同的时间资源单位,基站在第一时间资源单位之前的第五时间资源单位上传输下行数据信息,基站在第一时间资源单位上传输与该下行数据信息对应的上行反馈信息,第四时间资源单位为提前于第一时间资源单位的时间资源单位,该第四时间资源单位和第五时间资源单位都在第一时间资源单位之前,但是第四时间资源单位和第三时间资源单位是两个不同的时间资源单位,基站在第一时间资源单位或第四时间资源单位上传输下行调度信息,在满足上述条件时,表示基站确认可以在第一时间资源单位中指示用户设备进行全双工传输。
在本发明的一些实施例中,步骤201基站确定是否在第一时间资源单位中指示用户设备进行全双工传输之前,本发明实施例提供的全双工传输的控制方法还包括如下步骤:
H1、基站向用户设备发送广播信令或者专有信令,广播信令或者专有信令包括:基站配置的功率偏移和/或MCS偏移。
其中,功率偏移的预定义方式可以是基站通过广播信令或者专有信令来发送功率偏移和/或MCS偏移,基站通过广播信令或者专有信令发送功率偏移和/或MCS偏移之后,用户设备通过广播信令或者专有信令可以接收到该功率偏移和/或MCS偏移,然后就可以保存该功率偏移和/或MCS偏移,用于在接收对该功率偏移和/或MCS偏移的触发信令时触发该功率偏移和/或MCS偏移生效,其中,基站发送的专有信令可以是预置的无线资源控制信令,另外专有信令也可是基站和用户设备公知的其它信令。
在本发明的一些实施例中,步骤201基站确定是否在第一时间资源单位中指示用户设备进行全双工传输之前,本发明实施例提供的全双工传输的控制方法还包括如下步骤:
I1、基站在第一时间资源单位的调度授权信息中新增加信息用于携带功率偏移,或,基站在第一时间资源单位的调度授权信息中重新定义的原有信息中携带功率偏移,或,基站在配置的多个时间资源单位中的每个时间资源单位中 的调度授权信息中新增加信息用于携带功率偏移,或,基站在配置的多个时间资源单位中的每个时间资源单位中的调度授权信息中重新定义的原有信息中携带功率偏移。
也就是说,在功率偏移由基站发送给用户设备的实现方式中,基站可以通过如下方式来设置功率偏移,以使用户设备通过从调度授权信息中检测出功率偏移,例如,基站可以在调度授权信息中新增加信息,在新增加的信息中携带功率偏移,则用户设备可以检测调度授权信息中新增加的信息,又如,基站还可以对调度授权信息中的原有信息进行重新定义,则重新定义后的原有信息就可以用于携带功率偏移,因此用户设备可以检测调度授权信息中重新定义的原有信息。
202、若确定结果为可以在第一时间资源单位中指示用户设备进行全双工传输,基站在第一时间资源单位向用户设备发送包括指示用户设备进行全双工传输的调度授权信息。
在本发明实施例中,通过步骤201得到的确定结果可知,若确定结果为可以在第一时间资源单位中指示用户设备进行全双工传输,则说明基站可以在第一时间资源单位指示用户设备进行全双工传输,具体的,基站可以在第一时间资源单位向用户设备发送包括指示用户设备进行全双工传输的调度授权信息。由用户设备在第一时间资源单位对上述调度授权信息进行检测。
203、基站接收用户设备在获取到所述调度授权信息指示全双工传输之后按照对用于半双工传输的第一上行传输功率修正后得到的第一时间资源单位或者第二时间资源单位上传输的上行信号,第二时间资源单位为在时间上处于第一时间资源单位之后的时间资源单位。
在本发明实施例中,用户设备在第一时间资源单位获取到基站指示该用户设备可以进行全双工传输时,用户设备根据获取到的功率偏移对用于半双工传输的第一上行传输功率进行修正,得到用于全双工传输的第二上行传输功率,用户设备在第一时间资源单位或者第二时间资源单位进行全双工传输时,可以按照修正第一上行传输功率得到的第二上行传输功率进行上行信号的传输,基站可以接收用户设备在第一时间资源单位或者第二时间资源单位上传输的上行信号。由于用户设备使用的第二上行传输功率是按照用户设备是否进行全双工传输进行设置的,因此通过第二上行传输功率可以实现精确的功率控制,从 而可以避免自干扰,使得下行数据可以被正常检测,提高LTE***和WiFi***中实现的全双工传输的***增益。
通过前述实施例对本发明的描述可知,基站确定是否可以在第一时间资源单位中指示用户设备进行全双工传输,得到确定结果,若确定结果为可以在第一时间资源单位中指示用户设备进行全双工传输,基站在第一时间资源单位向用户设备发送包括指示用户设备进行全双工传输的调度授权信息,基站接收用户设备在获取到调度授权信息指示全双工传输之后按照对用于半双工传输的第一上行传输功率修正后得到的第二上行传输功率在第一时间资源单位或者第二时间资源单位上传输的上行信号,第二时间资源单位为在时间上处于第一时间资源单位之后的时间资源单位。本发明实施例中用户设备可以通过预置的功率偏移确定出第二上行传输功率,因此上行信道的功率控制可以按照用户设备确定进行全双工传输时对第一上行传输功率进行修正得到的第二上行传输功率进行正确设置,因此可以实现精确的功率控制,从而可以避免自干扰,使得下行数据可以被正常检测,提高无线通信***中全双工传输的***增益,本发明提供的方法可以用于LTE***和WiFi***。
为便于更好的理解和实施本发明实施例的上述方案,下面举例相应的应用场景来进行具体说明。
本发明实施例中分别以上下行授权调度作为基础,实现有效的全双工功率控制操作的解决方案。对于能够进行全双工传输的用户设备,引入一个功率偏移(以下简称Poffset),功率偏移被用来定义用于半双工传输的第一上行传输功率PPUSCH(或PPUCCH)和用于全双工传输的第二上行传输功率PFD之间的功率差值,具体的,以第一时间资源单位为第n个时间资源单位为例,其中,
对于PUSCH,存在PFD(n)=PPUSCH(n)-Poffset(n);
对于PUCCH,存在PFD(n)=PPUCCH(n)-Poffset(n)。
其中,n指的是需要修改上行传输功率的时间资源单位,举例说明,n可以指的是一个需要修改上行传输功率的子帧。
本发明实施例中,用户设备获取到的功率偏移可以是被预定义的或者在调度授权信息中指示。具体的,对于预定义的功率偏移,如果在相同时间资源单位检测到既用于上行调度又用于下行调度的调度信令,则该功率偏移被触发使 用于对第一上行传输功率的修正。
在本发明的一些实施例中,在第一时间资源单位的调度授权信息中用于功率偏移的指示可以是一个偏移值,或者在第一时间资源单位中通过1个比特(英文:bit)触发应用一个预定义的偏移值的生效。本发明的一些实施例中中还可以对功率偏移取一个特殊含义的偏移值,用户设备通过该特殊含义的功率偏移取值来取消一个已经调度的上行传输。
在本发明的一些实施例中,功率偏移的检测可以在一些定义的时间资源单位集合中执行,其中功率偏移可以被发送作为额外的比特,或者功率偏移可以凭借重新解释一个通常下行授权中的一些特定值得到。对于时间资源单位集合以外的时间资源单位,通常的下行上行授权都可以被分别检测。
在本发明的一些实施例中,调度授权和功率控制可应用于同一个时间资源单位,例如目前的第一时间资源单位,调度授权和功率控制也可以分别应用于两个时间资源单位,例如调度授权在第一时间资源单位中实现,而功率控制在第二时间资源单位中实现。
在本发明的一些实施例中,调整PUSCH传输功率的功率偏移可以隐含匹配于一个MCS偏移,或者基站发信令通知功率偏移时,同时显性信令通知一个MCS偏移。具体的,MCS偏移的具体使用与功率偏移相类似,例如:对于PUSCH,MCSFD(n)=MCSPUSCH(n)-MCSoffset(n)。
接下来以第一时间资源单位为第n时间资源单位为例,本发明实施例中可以采用多种方法使得一个用户设备获知在第n个时间资源单位上是否存在全双工传输。例如,一个上行授权在第n-4个时间资源单位被发送,接着一个下行授权在第n时间资源单位被发送。基于下行和上行的调度时刻,用户设备可以知道在第n个时间资源单位既有下行调度又有上行调度。又如,可以在一个单一的调度授权中同时指示在第n个时间资源单位的的上行调度和下行调度。接下来对上下行的调度检测不在同一个时间资源单位为例进行说明。
在本发明的一种实现方式中,通过配置功率偏移,用户设备可以基于第n个时间资源单位是否有全双工传输来调整第二上行传输功率,是否有全双工传输可以通过调度授权检测获知。接下来以时间资源单位具体为子帧为例,例如,如图3-a所示,第n-t1个子帧为调度授权A,第n-t2个子帧为调度授权B,当调度授权A和B都被检测到时,用户设备从基于上行授权A中的功率控制命 令中得到用于半双工传输的第一上行传输功率,使用预定义的功率偏移对该第一上行传输功率进行修正,得到第二上行传输功率。并且对于PUSCH传输,也将基于MCS偏移用于对第一MCS索引的修正。MCS偏移可以通过与功率偏移的相互匹配关系得到,例如MCSoffset=f(Poffset),或者MCS偏移也可以被显性信令通知给用户设备。
在本发明的另一种实现方式中,用户设备将基于在下行授权B中检测到的功率偏移用于调整第一上行传输功率。在图3-a中,在下行授权B中可以有1比特的字段,如果该字段是1的话,用户设备将应用一个固定的功率偏移;或者在下行授权B中有一个或多个比特,可用于指示功率偏移的具体取值。基于这个下行授权B中的功率偏移,及上行授权A中的第一上行传输功率,用户设备可得到用于全双工传输的第二上行传输功率。
在本发明的一些实施例中,对于在下行授权B中传输的功率偏移,一个特殊取值的功率偏移可以被用来阻止相同子帧中与PDSCH同时传输的PUSCH传输。
在本发明的一些实施例中,功率偏移在下行授权B指示可以导致一个更大的下行控制信息(英文全称:Downlink Control Information,英文简称:DCI)的尺寸,为了减少这种负荷,这种大的DCI不需要在每个子帧中都被检测,而只在定义的子帧集合中进行检测,而子帧集合以外的子帧只检测上行调度或者下行调度。
尽管在图3-a所示的例子中,第n个子帧的下行授权是提前t2ms发送的,t2可以被设置为0以避免时延,在这种情形下,用户设备可以被配置总是发送一个简短的PUSCH,该PUSCH在每个子帧的下行授权检测之后发送。
请参阅如图3-b所示,仍以时间资源单位具体为子帧为例,如果用户设备在第n-t1个子帧检测到PDSCH D,需要在第n个子帧反馈ACK或NACK。反馈前,用户设备也尽力检测相同第n个子帧上的潜在的下行调度。例如,如果收到第n个子帧的下行授权,比如在第n-t2个的下行授权E,或者第n个子帧的下行授权F,意味着ACK/NACK将在下行接收时同时发送ACK或NACK。在这种情况下,用户设备将根据预定义的功率偏移调整ACK或NACK的传输功率,或者基于下行调度的E或F中的功率偏移进行调整。注意到,如果下行预调度未被配置,并且用户设备在上行传输前需要在相同子帧上检测下行授 权,ACK或NACK需要被以简短的格式发送,允许下行授权有足够的检测时间。
需要说明的是,全双工传输是否应用功率控制可以是用户设备特定的配置,也可以被PDCCH动态的激活/去激活,例如可以通过无线资源控制协议(英文全称:Radio Resource Control,英文简称:RRC)信令配置,通过下行授权中的1个比特来通知是否应用这种规则。
通过如上对本发明的举例说明可知,本发明实施例提供的方法能够用于全双工传输的更精确地功率控制。
需要说明的是,对于前述的各方法实施例,为了简单描述,故将其都表述为一系列的动作组合,但是本领域技术人员应该知悉,本发明并不受所描述的动作顺序的限制,因为依据本发明,某些步骤可以采用其他顺序或者同时进行。其次,本领域技术人员也应该知悉,说明书中所描述的实施例均属于优选实施例,所涉及的动作和模块并不一定是本发明所必须的。
