图1C为一种针对接入连接上波束的配置示意图,图1C示出了周期性转发资源配置(Periodic Fwd Resource Set),包括周期性波束指示(Periodic beam indication)的配置情况。周期转发资源配置可以对多个资源信息进行周期配置,每个资源信息具有各自的标识,如ID。ID可以具有范围,如0-31,最大数量为32个。
每个资源信息包括波束标识和时域信息,波束标识具有范围,如0-63,最大数量为64个。Periodic Fwd Resource#0表示资源信息ID为0的资源信息,Periodic Fwd Resource#1表示资源信息ID为1的资源信息,以此类推。图1B中还示出了周期转发资源配置中的其他信息,如子载波间隔(Sub Carrier Space,SCS)、周期(periodicity)、优先级标志(priority flag)等。
图1D为一种针对接入连接上波束的配置示意图,图1C示出了半静态转发资源配置(Semipersistent Fwd Resource Set),包括半静态波束指示(Semi-persistent beam indication)的配置情况。半静态转发资源配置可以对多个资源信息进行半静态配置,每个资源信息具有各自的标识,如ID。ID可以具有范围,如0-31,最大数量为32个。
每个资源信息包括波束标识和时域信息,波束标识具有范围,如0-63,最大数量为64个。SemiPersistent Fwd Resource#0表示资源信息ID为0的资源信息,SemiPersistent Fwd Resource#1表示资源信息ID为1的资源信息,以此类推。图1D中还示出了半静态转发资源配置中的其他信息,如子载波间隔(Sub Carrier Space,SCS)、周期(periodicity)、优先级标志(priority flag)等。
图1E为一种针对接入连接上波束的配置示意图,图1E示出了非周期性转发资源配置(Aperiodic Fwd Config),包括非周期性波束指示(Aperiodic beam indication)的配置情况。非周期转发资源配置可以对多个资源信息进行非周期配置,每个资源信息具有各自的非周期时域资源标识,如ID。ID可以具有范围,如0-31,最大数量为32个。

由上述图1C至图1E所示,不管是周期波束指示、非周期波束指示还是半静态波束指示的配置中,都只配置了时域资源。波束对应的频域资源并未配置,所有被指示使用的波束在NCR-Fwd全带宽(band)上发送,当前的配置可能会造成干扰,且不够灵活,比如无法支持下图1F中的波束配置。因此,需要对波束指示信令进行增强。
在增强时,对于周期性波束指示,如同步信号和PBCH块(Synchronization Signal and PBCH block,SSB),频域资源大小是固定的。对于非周期波束指示或者半静态波束指示,例如动态调度用户数据,其频域大小是不固定的。由于频域大小的不固定性,很难精确的为每次波束指示分配精确的频率资源,所以需要为不同的波束指示确定合理的频域资源指示方法。
图2A是根据本公开实施例示出的一种波束配置的处理方法的交互示意图。如图2A所示,本公

示例性地,一个RBG可包括2、4、6或8个RB等。
在一些实施例中,频率信息包括索引值;一个索引值指代一个频率信息。
根据频率信息中的索引值即可查找出关联的频率信息,从而确定对应的频域资源,索引值的信息量的大小远小于一个频率信息的信息量的大小,这样即可减小第一信息的信息量,节省了信令开销。

在一些实施例中,频率信息,包含在集合信息中;频率信息指示的频域位置用于资源集合中的各传输资源。
在图1C至图1D中所示的集合信息中增加频域信息,即集合信息中包括频域信息,该频域信息为集合信息中各个资源信息所指示的传输资源共用的频域信息。该频域信息对集合信息内各个资源信息的波束配置有效,通过一个频域信息即可实现对一个集合信息内各个资源的频域信息的配置,在实现对频域资源配置的同时,减少了第一信息的信息量,从而减少了信令的开销。

S2103:发送下行控制信息DCI。
在一些实施例中,接入网设备发送下行控制信息DCI。
在一些实施例中,接入网设备向第一设备发送下行控制信息DCI。
在一些实施例中,当所述DCI用于控制连接时,所述DCI由第一加扰序列加扰;
当所述DCI用于接入连接时,所述DCI由第二加扰序列加扰;
所述第二加扰序列不同于所述第一加扰序列。

针对不同连接的DCI的加扰序列不同,方便第一设备根据解扰序列确定出当前接收到的DCI针对的连接,从而减少信令开销。

由于周期性的波束配置和半静态的波束配置,其频域信息一旦配置就和波束信息进行绑定了,无须DCI调度就可以按照配置信息执行即可。
由于非周期性的波束配置也可以称之为动态的波束配置。动态的波束配置是针对临时或突发的传输需求的波束配置,因此具有不定时性。在通过RRC消息完成频域信息配置之后,通过DCI针对已配置的频域信息和波束进行调度,如此,被调度的波束用于非周期性的传输。
示例性地,DCI携带有第一信息中某个波束的波束标识,则说明DCI调度该波束。
又示例性地,DCI包括比特位图,比特位图中一个比特可对应于一个波束或者一个波束组合,比特位图中为第一取值的比特对应的波束被调度,其他波束未被调度,从而通过DCI实现对第一信息配置的多个波束中的一个或多个波束的到动态调度。
使用DCI进行波束调度,具有动态性好以及及时性高的特点。

在图1D的基础上,在各个资源信息中增加频域信息,资源信息中包括频域信息、时域信息以及波束标识,各个资源信息对通过各自包含的频域信息指示频域位置。提高了对接入连接的半静态波束的频域位置的准确度,减少各个资源信息对应波束的频域位置之间的干扰,提高信号的传输质量,同时增加半静态波束配置的灵活性。

在一些实施例中,频率信息包括索引值;一个索引值指代一个频率信息。

上述步骤S4101至S4102可用于针对非周期性的波束配置。
由于非周期性的波束配置也可以称之为动态的波束配置。动态的波束配置是针对临时或突发的传输需求的波束配置,因此具有不定时性。在通过RRC消息完成频域信息配置之后,通过DCI针对已配置的频域信息和波束进行调度,如此,被调度的波束用于非周期性的传输。

在一些实施例中,对于NCR的接入连接的波束位置,支持频域资源指示。
在一些实施例中,频域资源(frequency resource)的指示内容包括以下至少之一:
选项1:直接指示频率资源信息,指示内容至少包括其一:
{参考频点,RB偏移量,RB长度}。
在一些实施例中,考频点可以是缺省的,此时中心频率为预定义的值,比如NCR-MT所在小区的中心频率。
在一些实施例中,RB偏移量和RB长度也可以理解为频率位置(frequency location)和带宽(bandwidth)。
在一些实施例中,RB偏移量和RB长度可以通过RRC表格定义,在波束位置配置(beam indication configuration)中直接通过表格中的索引值index指示。

在一些实施例中,基站通过RRC消息为非周期波束指示配置了多组频率资源,比如通过参数AperiodicFwdFreqResource(参考图1E)进行配置,每组都包括{参考频点,RB偏移量,RB长度}且对应一个ID,基站通过DCI指示非周期波束时,在DCI中包括该ID。
在一些实施例中,基站通过RRC为周期/半静态波束指示配置频率资源,直接在RRC参数中包含:参考频点,RB偏移量和RB长度。
选项2:复用现有协议中UE/NCR-MT使用的频域资源定义,如BWP和分量载波(CC)。
例如,基站为NCR-MT配置了4个专用BWP,此时控制信息(side control information)通过DCI format 2-8承载,DCI format 2-8在BWP#2上传输,在DCI中指示波束的频域资源是BWP#1。
例如,基站为NCR-MT配置了3个服务小区,在接入连接的周期波束资源配置(access link
periodic forwarding resource set configuration)中指示波束的频域资源是CC#2。
在一些实施例中,在基站进行频域配置之前,需要提前知道NCR的频域能力,获取该信息可以通过以下两种方式之一:
方式1:网络通过操作维护管理设备(Operation Administration and Maintenance,OAM)向NCR和基站指示NCR-Fwd和/或NCR-MT的频率能力。
方式2:NCR通过UE能力向基站上报自己的频率能力。
上述频域资源指示内容,选项2的方法适用于支持与接入网设备进行带内通信的NCR,无法用于支持带外通信的NCR,而选项1的方法可以适用于同时支持与接入网设备进行带内通信和带外通信的NCR。
上述方法也可以应用于RIS等设备。
