- the old and new subcarrier configuration intervals are 16.5 ms. If it is in the slot of 0.5ms, it needs to be expressed as 33 slots, which requires 6 bits. If the sub-region is represented, 5 bits are required, 4 bits represent 16 ms in units of ms, and 1 bit represents a slot of 0.5 ms.
- the number of bits required for the time domain start time indication depends on the maximum time and unit granularity (1 ms, 0.5 ms, etc.) that can be sustained per seed carrier configuration.
- the time domain end position of the interval of the new subcarriers can be indicated in the same manner.
- the wireless communication network supports different CP lengths, so the wireless communication network needs to inform the UE (terminal) of the CP length used for the interval of the new subcarriers.
- the length of the CP can be expressed in a few bits, and the number of bits required depends on the type of CP length available. For example, if the wireless communication network has 5 different CP length types, then 3 bits are needed to indicate the CP length used.
- the above numerical configuration information can be transmitted in an RRC message.
- the change of the value configuration information of the UE may be notified in the DCI message.
- the indication bit of the required starting position of the time in this case can be greatly reduced.
- the change of the configuration information of the next frame value may be indicated in the current frame.
- the change of the numerical configuration information may be indicated several frames (or several slots) in advance.
- the number of frames in advance may be specified by the standard, or may be configured by the wireless communication network, and the DCI may indicate the number of frames or the number of slots advanced to the UE.
- the change of the value configuration information is applicable to all UEs in the wireless communication network, so it is necessary to notify all UEs of the change of the value configuration information, and therefore the changed value may also be included in the broadcast channel or the synchronization signal.
- the configuration information is then detected by all UEs.
- the wireless communication network can provide more flexible multiplexing.
- the indication of the interval of the new subcarrier is the same as that in the fifth embodiment.
- the time domain start position and/or the time domain end position of the interval of the new subcarriers, and the CP length can also be indicated by the method described in Embodiment 5.
- each seed carrier configuration is selected only at the beginning or the end of the frequency domain. Notify the UE as the default frequency domain is fully multiplexed. If there is no blank resource in the frequency domain, then each seed carrier configuration is notified to the UE in the start and end positions of the frequency domain.
- the frequency domain information may also inform the UE in another way, namely the bandwidth of the subband and its corresponding central carrier frequency or (virtual) DC carrier position.
- the frequency domain resources of the interval of each of the subcarriers may also be discontinuous. Therefore, the frequency hopping information or all subband frequency domain information corresponding to the interval of the subcarrier needs to be notified to the UE.
- the transform of the subcarrier configuration is UE level, that is, the subcarrier configuration of some UEs will be transformed, and the other UEs still use the previous subcarrier configuration. In this case, only the affected UEs need to be notified.
- UE1, UE2, UE3 are using the spacing of the subcarriers f 1, f 2, f 3 .
- the configuration information of UE1 is unchanged, and both UE2 and UE3 use the interval f 3 of the subcarriers, and the bandwidth becomes the sum of the bandwidths of the previous two subbands. Therefore, in the first frame, UE1 detects that the subcarrier configuration is unchanged, and UE2 and UE3 detect that the subcarrier configuration will change, and at the same time, detect corresponding numerical configuration information.
- the multiplexing of the multiple subcarrier configurations may also be a predefined set of subcarrier configurations, which may be a time domain multiplexing combination or a frequency domain multiplexing combination of multiple subcarrier configurations, such as Figure 8 and Figure 9.
- the wireless communication network notifies the UE to the UE in advance, and when the subcarrier configuration change occurs, only the identifier or index (collectively referred to as the numeric configuration information number) of the UE subcarrier configuration needs to be notified.
- the UE reads the corresponding subcarrier configuration multiplexing information according to the identifier or index of the subcarrier configuration, and then performs detection on the corresponding resource by using the corresponding subcarrier configuration.
- Such subcarrier transformations may be at the wireless communication network level or may be for certain UEs.
- each configuration change needs to notify all UEs.
- the configured transform may be at the wireless communication network level, notifying all UEs, or only the affected UEs; for example, in the first three In the frame, UE1 using the interval f1 of the subcarrier may consider that the subcarrier configuration has not changed, and UE2 and UE3 using the intervals f2 and f3 of the subcarrier need to be informed of the new configuration information; in the fourth frame, the subcarrier configuration The changes need to be notified to all UEs.
- the UE may obtain information of the subcarrier configuration by blind detection.
- the UE performs blind detection with all possible subcarrier configurations over the entire wireless communication network bandwidth, thereby obtaining information for multiplexing of the current subcarrier configuration.
- the wireless communication network needs to add a small amount of signaling to indicate these locations.
- the physical layer may trigger through the DCI message, and after receiving the DCI message, trigger the UE to start blind detection.
- the technical solution of the present disclosure is applicable not only to scenarios in which different subcarrier configurations are multiplexed in 5G communication, but also to scenarios in which various parameter configurations are multiplexed in future mobile communications.
- What is shown in the schematic of the present disclosure is the frame structure of the downlink transmission, but is also applicable to the uplink transmission.
- the illustration is only a simple diagram, and the guard bands or guard intervals that may be included between the intervals of different subcarriers are not shown, but do not affect the use of the method.

一般来说,UE(终端)在初始接入无线通信网络后,会得到无线通信网络的数值配置(Numerology)信息,例如子载波的间隔大小,子载波的间隔对应的子带带宽等。由于业务存在时效性,因此不同时刻在无线通信网络中传输的业务可能会不同,而不同的子载波的间隔对应的带宽服务于不同的业务,当业务发生变化后,之前的子载波配置就可能不再适用,如果仍然使用初始接入时获得的数值配置信息进行数据传输,将不能适应不同业务的变换。

无线通信网络的多载波的间隔复用可以在时域也可以在频域。当无线通信网络的多数值配置是时分复用时,如图1所示,在不同的时间段使用不同的子载波的间隔,而整个频段上的子载波的间隔是一样的。当多数值配置是频分复用时,如图2所示,在频域的不同子频带上使用不同的子载波间隔,而这种配置在时域上是不变的。
一般来说,UE(终端)在初始接入无线通信网络后,会得到无线通信网络的数值配置信息,例如子载波的间隔大小,子载波的间隔对应的子带带宽等。由于业务存在时效性,因此不同时刻在无线通信网络中传输的业务可能会不同,而不同的子载波的间隔对应的带宽服务于不同的业务,当业务发生变化后,之前的子载波配置就可能不再适用,如果仍然使用初始接入时获得

进一步地,所述信息获取模块41用于接收所述无线通信网络节点发送的指示所述终端数值配置信息发生变化的下行控制消息,对多个数值配置信息一一进行检测,从所述多个数值配置信息中检测出变化后的数值配置信息;或接收所述无线通信网络节点发送的指示所述终端数值配置信息发生变化的广播消息或同步信号,对多个数值配置信息一一进行检测,从所述多个数值配置信息中检测出变化后的子载波配置信息;或接收所述无线通信网络节点发送的指示所述终端数值配置信息发生变化的无线资源控制消息,对多个数值配置信息一一进行检测,从所述多个数值配置信息中检测出变化后的数值配置信息。
进一步地,所述装置还包括:对应关系接收模块43,用于接收所述无线通信网络节点下发的多个数值配置信息与多个数值配置信息编号之间的对应关系;所述信息获取模块41用于接收所述无线通信网络节点通过下行控制消息下发的变化后的数值配置信息对应的数值配置信息编号,根据所述数值配置信息编号检测出变化后的数值配置信息;或接收所述无线通信网络节点通过广播消息或同步信号下发的变化后的数值配置信息对应的数值配置信息编号,根据所述数值配置信息编号检测出变化后的数值配置信息;或接收所述无线通信网络节点通过无线资源控制消息下发的变化后的数值配置信息对应的数值配置信息编号,根据所述数值配置信息编号检测出变化后的数值配置
信息。
数值配置信息编号可以是数值配置信息的标识,还可以是数值配置信息的索引。具体地,可以事先建立一个数值配置信息集合,在该集合中包括有多个数值配置信息,每一数值配置信息对应有一数值配置信息编号,事先将数值配置信息集合通知给终端,在数值配置信息发生变化后,只需要将变化后的数值配置信息编号发送给终端,终端直接检索数值配置信息编号即可得到变化后的数值配置信息。
进一步地,所述信息获取模块41用于接收所述无线通信网络节点通过预设消息或信号下发的变化后的数值配置信息。
进一步地,所述装置还包括:变化指示接收模块44,用于接收所述无线通信网络节点下发的数值配置信息变化指示;所述信息获取模块41用于根据所述数值配置信息变化指示判断出数值配置信息发生变化,并从接收到的预设消息或信号中检测出变化后的数值配置信息。数值配置信息变化指示可以用1比特来表示,通过数值配置信息变化指示可以减少终端的检测,使得终端只在发生数值配置信息发生变化后才去进行检测。
进一步地,所述信息获取模块41用于接收所述无线通信网络节点通过下行控制消息下发的变化后的数值配置信息;或接收所述无线通信网络节点通过广播消息或同步信号下发的变化后的数值配置信息;或接收所述无线通信网络节点通过无线资源控制消息下发的变化后的数值配置信息。
其中,通过RRC消息进行通知适用于半静态的子载波配置,通过DCI消息进行通知适用于动态子载波配置。
在一些实施例中,如果多数值配置在时域的复用如图1所示。无线通信网络可用作灵活子载波配置的子载波的间隔是{f1,f2,f3}。假设f2=15kHz,则图1面包含了两个子帧,共2ms。无线通信网络在0.5ms的时候进行了第一次子载波配置的变换,在1ms的时候进行了第二次子载波配置变换。在这种情况下,由于可用的子载波的间隔有3种,因此可以只用2比特指示这三种不同的子载波的间隔。例如:01表示f1,10表示f2,11表示f3。当然也可以用其他的比特组合指示这三种不同的子载波配置。当可用的子载波的间隔的数目增加时,所需的比特数也会相应增加。
为了减少新子载波的间隔(即变化后的子载波的间隔)的时域起始时间的指示比特,时域起始位置可以用旧子载波的间隔(即变化前的子载波的间隔)的持续时长来表示,或者新旧子载波的间隔的相对位置来表示。例如图1中以0.5ms的slot为单位,则f1的起始位置是一个slot。f2的起始位置也是1个slot,因为相对于f1,它们之间的间隔是1个slot。
进一步地,还可以用大小时间颗粒度结合的方式减小指示比特。指示比特可以分为两个区域,一个指示大颗粒度的时间,另一个指示小颗粒度的时间。例如,新旧两种子载波配置间隔是16.5ms。如果以0.5ms的slot为单位,则需要表示为33个slot,需要6比特。如果分区域表示,则需要5比特,4比特以ms为单位表示16ms,1比特表示0.5ms的slot。时域起始时间指示所需要的比特数取决于每种子载波配置可以持续的最长时间和单位的颗粒度大小(1ms,0.5ms等等)。新的子载波的间隔的时域结束位置可用同样的方式去指示。
无线通信网络支持不同CP长度,因此无线通信网络需要通知UE(终端)新子载波的间隔使用的CP长度。CP长度可以用几比特表示,需要的比特数取决于可用的CP长度类型。例如,无线通信网络有5种不同的CP长度类型,则需要3比特去指示使用的CP长度。
对于半静态指示,上述数值配置信息可以在RRC消息中传输。对于动态指示,可以在DCI消息中通知UE数值配置信息的变化。这种情况下需要的时间起始位置的指示比特可以大大减小。可以在当前帧指示下一帧数值配置信息的变化,如果无线通信网络处理或者调度准备时间不够,则可以提前几帧(或者几个slot)指示数值配置信息的变化。提前的帧数可以是标准规定的,也可以是无线通信网络配置的,DCI只要指示给UE提前的帧数或者slot数就可以。
对于时分复用的情况,数值配置信息的变化适用于无线通信网络下的所有UE,因此需要将数值配置信息的变化通知给所有UE,因此也可以在广播信道或者同步信号中包含变化后的数值配置信息,然后由所有UE检测。
在一些实施例中,如果多种子载波配置在频域复用且支持半静态或者动态变换,如图7所示,则无线通信网络可以提供更灵活的复用。
如图7所示,假设也只有三种可用作灵活子载波配置的子载波的间隔{f1,f2,f3}。因此新子载波的间隔的指示同实施例五。此外,新子载波的间隔的时域起始位置和/或时域结束位置,CP长度也可以使用实施例五所述的方式去指示。
对于新子载波的间隔的频域信息,如果是无线通信网络级的变换,即需要通知无线通信网络下的所有UE,则每种子载波配置在频域的起始位置或者结束位置只选其一通知给UE即可,因为默认频域是被全部复用的。若频域有空白资源不用,则此时每种子载波配置在频域的起始位置和结束位置都要通知给UE。该频域信息也可以用另外一种方式告知UE,即子带的带宽和其对应的中心载频或者(虚拟)直流载波位置。此外,每种子载波的间隔的频域资源也可以是不连续的,因此跳频信息或者该子载波的间隔对应的所有子带频域信息都需要通知给UE。
对于频分复用的情况,如果子载波配置的变换是UE级别的,也就是说,一些UE的子载波配置会发生变换,而其他UE还是使用之前的子载波配置。这种情况下,只需要通知受影响的UE。如图7所示,假设UE1,UE2,UE3分别使用子载波的间隔f1,f2,f3。1ms后,UE1的配置信息不变,而UE2和UE3都使用子载波的间隔f3,带宽则变为之前两者子带带宽之和。因此,在第一帧里面,UE1检测到子载波配置不变,而UE2和UE3检测到子载波配置将发生变化,同时去检测相应的数值配置信息。
在一些实施例中,多种子载波配置的复用也可以是预定义的一些子载波配置集合,这些预定义的配置可以是多种子载波配置的时域复用组合或者频域复用组合,如图8和图9所示。在这种情况下,无线通信网络事先将这些集合通知给UE,在发生子载波配置变化时,只需要通知给UE子载波配置的标识或者索引(统称为数值配置信息编号)即可。UE根据子载波配置的标识或者索引读取相应的子载波配置复用信息,然后在相应的资源上用对应的子载波配置做检测。
这种子载波变换可以是无线通信网络级的,也可以是针对某些UE的。例如图8中每次配置变换都需要通知所有UE。在图9中,配置的变换可以是无线通信网络级的,通知所有UE,也可以只通知受影响的UE;例如在前三
帧里面,使用子载波的间隔f1的UE1可以认为子载波配置没有变,而使用子载波的间隔f2和f3的UE2和UE3则需要被告知新的配置信息;在第四帧里面,子载波配置的改变需要通知所有UE。
在一些实施例中,为了减少信令传输的开销,UE可以通过盲检得到子载波配置的信息。UE在整个无线通信网络带宽上用所有可能的子载波配置进行盲检,从而得到当前子载波配置复用的信息。此外,为了减少UE盲检的次数,可以限制子载波配置的变换为周期性的或者预定义的位置(即数值配置信息发生变化的时间点),则UE只需要在这些位置盲检即可。同时,无线通信网络需要增加少量信令去指示这些位置。
对于周期性或者预定义位置的子载波配置变换,可以通过RRC消息去配置,也可以把这些信息包含在广播信道或者同步信号中。对于非周期的子载波配置变换,可以在物理层通过DCI消息进行触发,在接收DCI消息后,触发UE开始盲检。
