- the terminal device can perform transmission switching on these two carriers.
- the information element of the frequency band combination list (uplink handover frequency band combination list) is used to report the radio frequency chain handover capability.
- a frequency band combination list information element contains one or more new frequency band combinations.
- the frequency band combination information element includes frequency band parameters of all frequency bands in the frequency band combination and a feature set (Featureset) combination corresponding to the frequency band combination.
- the band combination information element also includes a band pair list (ie, a first band set list) (supportedBandPairListNR-r16).
- the band pair list contains one or more uplink switching band pairs (ULTxSwitchingBandPair-r16).
- the uplink switching frequency band pair is a frequency band pair that supports dynamic RF chain switching, including two frequency bands (bandIndexUL1-r16 and bandIndexUL2-r16), which means that the terminal device can perform dynamic RF chain switching on the carriers belonging to these two frequency bands. These two frequency bands must be frequency bands in the band combination.
- the uplink switching frequency band pair information element also includes a switching time (uplinkTxSwitchingPeriod-r16), indicating the switching time required for the radio frequency chain to perform dynamic radio frequency chain switching on the carriers belonging to the two frequency bands. Table 1 shows the band combination list information element.

- Table 3 shows the uplink switching frequency band pairs.
- radio frequency chain used herein may refer to a transmit channel (Transmitter, TX), and may be called a radio frequency (radio frequency, RF) transmit channel.
- the transmission channel can work in the following manner, but is not limited to the following manner: the transmission channel can receive the baseband signal from the baseband chip, and perform radio frequency processing (such as up-conversion, amplification and filtering) on the baseband signal to obtain a radio frequency signal , and finally radiate the radio frequency signal into space through the antenna.
- radio frequency processing such as up-conversion, amplification and filtering
- the transmit channel may include an antenna switch, an antenna tuner, a low noise amplifier (Low Noise Amplifier, LNA), a power amplifier (Power Amplifier, PA), a mixer (Mixer), a local oscillator (Local Oscillator, LO) , filter (Filter) and other electronic devices, these electronic devices can be integrated into one or more chips as required.
- the antenna can also sometimes be considered as part of the transmit channel.
- the transmit channels are referred to as radio frequency chains for short.
- the radio frequency chain in this application may also be replaced by an antenna, a radio frequency, a transmission channel, a transmission port, a reception channel or any combination thereof.
- a new information element of the frequency band combination list of R17 is newly created to distinguish it from the information element of the frequency band combination list of R16.
- R17 the enhancement of R17 compared to R16, one is to increase the radio frequency chain of carrier 1, and the other is to change the carrier of the frequency band from one carrier to two continuous carriers.
- both R16 and R17 are aimed at switching between two frequency bands.
- a terminal device supports 2 radio frequency chains on one carrier, it must also support 1 radio frequency chain, and a terminal device supports 2 consecutive carriers on a frequency band, then it must also support 1 carrier on this frequency band.
- a terminal device that supports R17 must support R16, but a terminal device that supports R16 does not necessarily support R17. That is to say, if a terminal device supports R17 radio frequency chain switching, the frequency band pair and frequency band combination supported by the R17 radio frequency chain switching must belong to the frequency band pair and frequency band combination supported by the R16 radio frequency chain switching of the UE terminal device. Therefore, when reporting frequency band pairs and frequency band combinations, if the frequency band pairs and frequency band combinations of R16 have been completely reported, then the frequency band information (for example, frequency band identification (identity, ID)) can be multiplexed by R17 to save signaling overhead. Therefore, the frequency band combination cell of R17 follows the frequency band information of the frequency band combination cell of R16.
- ID frequency band identification
- the uplink transmission mode (for example, the uplink transmission mode according to R18) may also support more than 2 frequency bands in a frequency band pair. In this case, it is no longer possible to request the correspondence between the frequency band pairs in the R18 frequency band pair list and R16. Thus, the signaling reporting overhead of the R18 cannot be saved.

Description
本公开涉及通信领域,并且更具体地,涉及终端设备能力上报的方法以及相关联的通信装置、介质和芯片。
随着通信技术的发展,已经提出了载波聚合技术(carrier aggregation,CA)。根据载波聚合技术,终端设备被配置多个小区,其中每个小区内包括一个下行载波以及0个到2个上行载波。终端设备可以激活多个小区中的部分小区,但有些终端设备的上行能力受限,最多只能配置和激活2个上行载波。根据已经提出的一种上行传输模式,如果终端设备支持2个上行载波(例如,载波1和载波2),则终端设备可以在这两个载波上进行传输切换,从而提高射频链的利用率。例如,在一种情况下,终端设备可以在载波1上有1个射频链,在载波2上有1个射频链,在另一种情况下,终端设备可以在载波1没有射频链,在载波2上有2个射频链。可以看出,终端设备在载波1最大支持1个射频链,在载波2最大支持2个射频链。终端设备可以在这两个情况之间进行切换,即可以把1个射频链在2个载波之间进行切换,而这两个情况之间切换需要切换时间。这个切换时间可以称之为上行链路切换间隔(uplink switching gap)。终端设备在上行链路切换间隔期间内不希望在2个载波的任何一个上面进行传输。此外,传统的上行传输模式被增强,因此,需要对增强的上行传输模式进行进一步地研究和讨论。
发明内容
本公开的示例实施例提供了在通信***中终端设备能力上报的方案。
在本公开的第一方面,提供了一种用于通信的方法。该方法包括终端设备向网络设备上报关于该终端设备的能力信息。该能力信息包括该终端设备支持的第一频段集合列表和该终端设备支持的第二频段集合列表。该第一频段集合列表包括第一数目的第一频段集合,每个第一频段集合的指示信息包括第二数目的频段的索引以及终端设备在频段之间切换的切换时间。第二频段集合列表指示第三数目的第二频段集合。第二频段集合的指示信息不包括频段索引。第二频段集合中的频段由与第二频段集合对应的多个连续的第一频段集合所包括的频段的索引指示。多个连续的第一频段集合包括第四数目的频段。该第一数目大于该第三数目,该第二数目小于该第四数目。以此方式,可以减少第二频段集合列表的上报量,从而节约信令开销。
在某些实施例中,在该第一频段集合列表中,与该第二频段集合存在对应关系的频段集合被排序在与该第二频段集合不存在对应关系的频段集合之前。在某些实施例中,能力信息还包括第一指示。该第一指示用于指示在该第一频段集合列表中与该第二频段集合存在对应关系的频段集合的数目。以此方式,在不上报频段索引的情况下,更容易确定第二频段集合与多个第一频段集合的对应关系。
在某些实施例中,该第二频段集合的指示信息还包括第一切换时间,该第一切换时间用于该第二频段集合包括的所有频段之间的切换。以此方式,减少了能力信息的上报量。
在某些实施例中,该第二频段集合的指示信息还包括多个切换时间,该多个切换时间分别用于该第二频段集合包括的任意两个频段之间的切换,该多个切换时间中的任何两个切换时间对应的切换频段中的至少一个频段不同。以此方式,终端设备在不同频段之间切换时,可以采用更短的切换时间。不会因为其他载波激活去激活,增加或释放,而改变切换时长。
在某些实施例中,该第二频段集合的指示信息还包括第二切换时间和第三切换时间,其中在该第二频段集合中的频段被分组时,该第二切换时间用于分组内的频段切换,该第三切换时间用于组间的切换。以此方式,终端设备在不同频段之间切换时,可以采用更短的切换时间。
在某些实施例中,该方法还包括:如果该第一切换时间小于与该第二频段集合对应的该多个连续的第一频段集合中的第四切换时间,该终端设备将该第一切换时间应用到与该第四切换时间对应的频段之间的切换。该方法还包括:如果该第一切换时间大于该第四切换时间,该终端设备将该第四切换时间应用到与该第四切换时间对应的频段之间的切换。以此方式,终端设备可以采用更短的切换时间。
在某些实施例中,该方法还包括:该终端设备基于来自该网络设备的配置或基于预先确定的配置来从该多个切换时间确定一个或多个目标切换时间;以及该终端设备将该一个或多个目标切换时间应用到该频段集合包括的频段之间的切换。以此方式,实现了网络设备对切换时间的配置。

在某些实施例中,在该第一频段组合列表中,与该第二频段组合存在对应关系的频段组合被排序在与该第二频段组合不存在对应关系的频段组合之前。在某些实施例中,该能力信息还包括第三指示,该第三指示用于指示在该第一频段组合列表中与该第二频段组合存在对应关系的频段组合的数目。以此方式,在不上报频段索引的情况下,更容易确定第二频段组合列表中的频段组合与第一频段列表中的频段组合的对应关系。
在某些实施例中,如果该终端设备在该第一频段组合列表中的第三频段组合包含第三频段、第四频段和第五频段,并且该终端设备在该第二频段组合列表中支持该第三频段、该第四频段、该第五频段之间的切换,则该第三频段组合的指示信息包括该第三频段的索引、该第四频段的索引、该第五频段的索引,并且第三频段组合对应的至少一组特征集合参数中该第五频段对应的MIMO层数为零。以此方式,实现了第一频段组合列表中的频段组合与第二频段组合列表中的频段组合的一一对应。
在某些实施例中,该第二频段组合所包括的频段集合包括该一个或多个连续的第一频段组合所包括的频段集合。在某些实施例中,该能力信息包括第二指示,该第二指示用于指示该第一频段组合可以作为该第二频段集合。在某些实施例中,该能力信息还包括第三指示,该第三指示用于指示在该第一频段组合列表中与该第二频段组合存在对应关系的频段组合的数目。以此方式,节约信令开销。
在某些实施例中,该第一数目大于或等于N*M,该第二数目为2,该第三数目为M,该第四数目为N,该第二频段集合列表中的第i+1个频段集合对应于该第一频段集合列表中的第i*N+1到第(i+1)*N频段集合,该第一频段集合列表中的第i*N+1到第(i+1)*N频段集合包括的N个频段为该第二频段集合列表中的第i+1个频段集合中包括的频段,其中N为不小于3的整数,i和M为自然数。此方式,可以减少第二频段集合列表的上报量,从而节约信令开销。

在某些实施例中,在该第一频段集合列表中,与该第二频段集合存在对应关系的频段集合被排序在与该第二频段集合不存在对应关系的频段集合之前。在某些实施例中,能力信息还包括第一指示。该第一指示用于指示在该第一频段集合列表中与该第二频段集合存在对应关系的频段集合的数目。以此方式,在不上报频段索引的情况下,更容易确定第二频段集合与多个第一频段集合的对应关系。这样避免基站复杂的判断,有利于基站实现。
在某些实施例中,该第二频段集合的指示信息还包括第一切换时间,该第一切换时间用于该第二频段集合包括的所有频段之间的切换。以此方式,减少了能力信息的上报量。
在某些实施例中,该第二频段集合的指示信息还包括多个切换时间,该多个切换时间分别用于该第二频段集合包括的任意两个频段之间的切换,该多个切换时间中的任何两个切换时间对应的切换频段中的至少一个频段不同。以此方式,终端设备在不同频段之间切换时,可以采用更短的切换时间。不会因为其他载波激活去激活,增加或释放,而改变切换时长。
在某些实施例中,该第二频段集合的指示信息还包括第二切换时间和第三切换时间,其中在该第二频段集合中的频段被分组时,该第二切换时间用于分组内的频段切换,该第三切换时间用于组间的切换。以此方式,终端设备在不同频段之间切换时,可以采用更短的切换时间。
在某些实施例中,该方法还包括:该网络设备向该终端设备发送配置,该配置指示一个或多个目标切换时间。以此方式,实现了网络设备对切换时间的配置。
在某些实施例中,该方法还包括:如果该第二频段集合的指示信息不包括切换时间信息,该网络设备确定与该第二频段集合对应的该多个连续的第一频段集合中的最长切换时间用于该第二频段集合包括的频段之间的切换;或如果该第二频段集合的指示信息不包括切换时间信息,该网络设备确定与该第二频段集合对应的该多个连续的第一频段集合中的多个切换时间分别用于该第二频段集合包括的对应的两个频段之间的切换。以此方式,可以减少能力信息的上报量。
在某些实施例中,该能力信息还包括:与该第一频段集合列表相关联的第一频段组合列表以及与该第二频段集合列表相关联的第二频段组合列表。该第一频段组合列表指示第五数 目的第一频段组合。第二频段组合列表指示第六数目的第二频段组合。第二频段组合与该第一频段组合列表中的一个或多个连续的第一频段组合对应。第五数目大于或等于该第六数目。第二频段组合的指示信息不包括频段索引。第二频段组合中的频段由与一个或多个连续的第一频段组合所包括的频段的索引指示。以此方式,可以减少第二频段组合列表的上报量,从而节约信令开销。
在某些实施例中,在该第一频段组合列表中,与该第二频段组合存在对应关系的频段组合被排序在与该第二频段组合不存在对应关系的频段组合之前。在某些实施例中,该能力信息还包括第三指示,该第三指示用于指示在该第一频段组合列表中与该第二频段组合存在对应关系的频段组合的数目。以此方式,在不上报频段索引的情况下,更容易确定第二频段组合列表中的频段组合与第一频段列表中的频段组合的对应关系。
在某些实施例中,如果该终端设备在该第一频段组合列表中的第三频段组合包含第三频段、第四频段和第五频段,并且该终端设备在该第二频段组合列表中支持该第三频段、该第四频段、该第五频段之间的切换,则该第三频段组合的指示信息包括该第三频段的索引、该第四频段的索引、该第五频段的索引,并且第三频段组合对应的至少一组特征集合参数中该第五频段对应的MIMO层数为零。以此方式,实现了第一频段组合列表中的频段组合与第二频段组合列表中的频段组合的一一对应。

在本公开中使用的术语“终端设备”指能够与网络设备之间或者彼此之间进行有线或无线通信的任何终端设备。本申请实施例涉及到的终端设备还可以称为终端,可以是一种具有无线收发功能的设备,其可以部署在陆地上,包括室内或室外、手持或车载;也可以部署在水面上(如轮船等);还可以部署在空中(例如飞机、气球和卫星上等)。终端设备可以是用户设备(User Equipment,UE),其中,UE包括具有无线通信功能的手持式设备、车载设备、可穿戴设备或计算设备。示例性地,UE可以是手机(Mobile Phone)、平板电脑或带无线收发功能的电脑。终端设备还可以是虚拟现实(Virtual Reality,VR)终端设备、增强现实(Augmented Reality,AR)终端设备、工业控制中的无线终端、无人驾驶中的无线终端、远程医疗中的无线终端、智能电网中的无线终端、智慧城市(Smart City)中的无线终端、智慧家庭(Smart Home)中的无线终端等等。本申请实施例中,用于实现终端的功能的装置可以是终端;也可以是能够支持终端实现该功能的装置,例如芯片***,该装置可以被安装在终端中。本申请实施例中,芯片***可以由芯片构成,也可以包括芯片和其他分立器件。本申请实施例提供的技术方案中,以用于实现终端的功能的装置是终端,以终端是UE为例,描述本申请实施例提供的技术方案。
在本公开中使用的术语“网络设备”是可以用于与终端设备通信的实体或节点。本申请实施例涉及到的网络设备包括接入网设备,例如基站(Base Station,BS),BS可以是一种部署在无线接入网中能够和终端进行无线通信的设备。其中,基站可能有多种形式,比如宏基站、微基站、中继站和接入点等。示例性地,本申请实施例涉及到的基站可以是5G中的基站或LTE中的基站,其中,5G中的基站还可以称为发送接收点(Transmission Reception Point,TRP)或gNB。本申请实施例中,用于实现网络设备的功能的装置可以是网络设备;也可以是能够支持网络设备实现该功能的装置,例如芯片***,该装置可以被安装在网络设备中。在本申请实施例提供的技术方案中,以用于实现网络设备的功能的装置是网络设备,以网络设备是基站为例,描述本申请实施例提供的技术方案。

如上所述,根据已经提出的一种上行传输模式,如果终端设备支持2个上行载波(例如,载波1和载波2),则终端设备可以在这两个载波上进行传输切换。例如,当前协议中版本16(Release 16,R16)的终端设备的能力中与射频链切换的能力上报是用了频段组合列表(上行切换频段组合列表)信元。一个频段组合列表信元包含一个或多个新的频段组合。频段组合信元包含这个频段组合中的所有频段的频段参数和这个频段组合对应的特征集合 (Featureset)组合。频段组合信元还包括频段对列表(即,第一频段集合列表)(supportedBandPairListNR-r16)。频段对列表包含一个或多个上行切换频段对(ULTxSwitchingBandPair-r16)。上行切换频段对为支持动态射频链切换的频段对,包含两个频段(bandIndexUL1-r16和bandIndexUL2-r16),即表示终端设备可以在属于这两个频段的载波上进行动态射频链切换。这两个频段必须是频段组合中的频段。上行切换频段对信元中还包含切换时间(uplinkTxSwitchingPeriod-r16),表示射频链在属于这两个频段的载波上进行动态射频链切换时需要的切换时间。表1示出了频段组合列表信元。表2示出了频段组合信元,其中表2中的uplinkTxSwitching-OptionSupport-r16表示所支持的模式,该模式可以为切换模式,或者并发模式,或者两者都支持,uplinkTxSwitching-PowerBoosting-r16表示功率提升字段。表3示出了上行切换频段对。

表3
本文中使用的术语“射频链”可以指代发射通道(Transmitter,TX),可以称为射频(radio frequency,RF)发射通道。在本公开中,发射通道可以是按照如下方式工作的,但不仅限于如下方式:发射通道可接收来自基带芯片的基带信号,对基带信号进行射频处理(如上变频、放大和滤波)以得到射频信号,并最终通过天线将该射频信号辐射到空间中。具体地,发射通道可以包括天线开关,天线调谐器,低噪声放大器(Low Noise Amplifier,LNA),功率放大器(Power Amplifier,PA),混频器(Mixer),本地振荡器(Local Oscillator,LO)、滤波器(Filter)等电子器件,这些电子器件可以根据需要集成到一个或多个芯片中。天线有时也可以认为是发射通道的一部分。在本公开中,发射通道均简称为射频链。可选的,本申请中射频链也可以替换为天线、射频、发射通道、发送端口、接收通道或者它们的任意组合。
进一步地,当前协议终端设备的能力中版本(R17)射频链切换的能力上报是新建了一个R17的频段组合列表信元,以与R16的频段组合列表信元进行区分。考虑到R17相比R16的增强一个是增加了载波1的射频链,另外一个是频段的载波从一个载波变为两个连续载波。也就是说,无论R16还是R17针对的都是2个频段之间的切换。同时考虑如果一个终端设备 在一个载波上支持2个射频链,那么必然也支持1个射频链,一个终端设备在一个频段上支持2个连续载波,那么也必然支持在这个频段上支持1个载波,反过来不一定成立。所以支持R17的终端设备必然支持R16,而支持R16的终端设备不一定支持R17。也就是说,如果一个终端设备支持R17的射频链切换,那么这个R17射频链切换支持的频段对和频段组合必然属于这个UE终端设备的R16射频链切换支持的频段对和频段组合。所以上报频段对和频段组合的时候,如果已经完全上报了R16的频段对和频段组合,那么其中的频段信息(例如,频段标识(identity,ID))可以来被R17复用,以节省信令开销。所以,R17的频段组合信元沿用了R16的频段组合信元的频段信息。
无论是根据R16还是R17的上行传输模式,只能支持一个频段对中包含2个频段的上报情况。然而,上行传输模式(例如,根据R18的上行传输模式)还可能支持一个频段对中包含2个以上的频段。在此情况下,无法再要求R18频段对列表中的频段对与R16的对应。进而无法节省R18的信令上报开销。因此,在终端设备支持在2个以上的频段上进行动态切换时,如何低开销的上报频段组合和频段对是亟待解决的。
此外,当前协议中终端设备在两个频段间进行切换时的切换时间是针对每个频段对上报的,不同频段对可以上报不同的切换时间。但是,由于传输模式可以支持一个频段对中包含2个以上的频段,因此终端设备在3个频段或者4个频段上的切换时间都有可能是不同的,如果只上报一个切换时间,则会造成时频资源的浪费。因此,在终端设备支持在2个以上的频段上进行动态切换时,如何上报终端设备在频段对上的切换时间也值得进一步研究。
针对上述问题以及其他潜在的问题,本公开的实施例涉及终端设备能力上报。终端设备向网络设备上报关于该终端设备的能力信息。该能力信息包括该终端设备支持的第一频段集合列表以及该终端设备支持的第二频段集合列表。该第一频段集合列表包括第一数目的第一频段集合。每个第一频段集合的指示信息包括第二数目的频段的索引以及该终端设备在频段之间切换的切换时间。该第二频段集合列表包括第三数目的第二频段集合。第二频段集合的指示信息不包括频段索引。该第二频段集合中的频段由与所述第二频段集合对应的多个连续的第一频段集合所包括的频段的索引指示。这些多个连续的第一频段集合包括第四数目的频段。第一数目大于第三数目。第二数目小于第四数目。以此方式,可以减少第二频段集合列表的上报量,从而节约信令开销。
图1示出了可以在其中实现本公开的实施例的通信环境100的示意图。通信环境100包括终端设备110-1、终端设备110-2、......、终端设备110-N,其可以统称为“终端设备110”,其中N为任意正整数。作为通信网络的一部分的通信环境100还包括网络设备120。终端设备110可以与网络设备120彼此通信。终端设备110还可以接收来自核心网设备的消息。本文中使用的术语“实体”是指可以实现特定功能的网元。如图1所示,终端设备110与网络设备120进行通信(即,通过Uu链路)。本文中使用的术语“上行链路(Uplink,UL)数据”指代由终端设备向网络设备发送的数据。本文中使用的术语“下行链路(Downlink,DL)数据”指代由网络设备向终端设备发送的数据。
通信环境100可以包括任何合适数目的设备和小区。在通信环境100中,终端设备110和网络设备120可以彼此通信数据和控制信息。应当理解,图1所示的多种设备的数目及其连接是为了说明的目的而给出的,没有提出任何限制。通信环境100可以包括适合于实现本公开的实施例的任何合适数目的设备和网络。
通信环境100中的通信可以根据任何适当的通信协议来实现,包括但不限于第一代蜂窝 通信协议(1G)、第二代蜂窝通信协议(2G)、第三代蜂窝通信协议(3G),***蜂窝通信协议(4G)和第五代蜂窝通信协议(5G)等之类的无线局域网通信协议,例如电气和电子工程师协会(IEEE)802.11等,和/或当前的任何其他协议已知或将来会发展。此外,通信可以利用任何适当的无线通信技术,包括但不限于:码分多址(Code Division Multiple Access,CDMA)、频分多址(Frequency Division Multiple Access,FDMA)、时分多址(Time Division Multiple Access,TDMA)、频分双工(Frequency Division Duplex,FDD)、时分双工(Time Division Duplex,TDD)、多输入多输出(Multi-Input Multi-Output,MIMO)、正交频分多路(Orthogonal Frequency Division Multiplexing OFDM)、离散傅立叶变换扩展OFDM(Discrete Fourier Transform-spread-OFDM,DFT-s-OFDM)和/或当前已知或将在其中开发的任何其他技术未来。
如图2A至图2C所示,终端设备110-1被基站配置了至少三个载波,即,载波201、载波202以及载波203。终端设备110-1可以在载波201、载波202以及载波203进行射频链切换,并且在这3个载波上的总射频链数量为2。在某些实施例中,每次射频链切换可以涉及2个载波。例如,如图2A所示,终端设备110-1将2个射频链从载波203切换到载波202,和/或从载波202切换到载波201。在其他实施例中,射频链切换可以涉及3个载波。如图2B所示,终端设备110-1将1个射频链载波203切换到载波202以及将另一个射频链载波从载波201切换到载波202。在某些实施例中,射频链切换可以只切换1个射频链。如图2C所示,终端设备110-1将1个射频链载波201切换到载波202。可以理解,图2A至图2C所示的射频链切换仅为示例性的,而非限制性的。本公开示例实施例可以应用于如图2A至图2C所示的场景中。本公开示例实施例也可以应用于未示出的其他场景中。
下文将参考附图来具体讨论本公开的示例实施例。为便于讨论,将参考图1的示例通信环境来描述根据本公开示例实施例的终端设备的能力上报的流程以及通信实体间信令交互。应理解,本公开的示例实施例可以类似应用于其他通信环境中。
在某些实施例中,网络设备230向终端设备110-1发送(3010)针对该终端设备能力查询的请求。本文中使用的术语“终端设备的能力”或“UE能力(UE capability)”可以指代终端设备支持哪些功能。蜂窝无线通信***依赖基站和终端设备之间准确高效地协调互通,其中终端设备的能力就是基站和终端设备之间协调的重要一环。基站知道终端设备能力之后才能对终端设备做出正确的调度。如果终端设备支持某个功能,那么基站可以给该终端设备配置该功能。如果终端设备不支持某个功能,那么基站便不可以给该终端设备配置该功能。
在接收到上述请求后,终端设备110-1可以解析该请求以获得终端设备能力上报需求信息。例如,针对该终端设备能力查询的请求可以包括用于指示终端设备110-1网络设备230想知道哪些终端设备能力。终端设备能力上报需求信息还可以包括以下一项或多项:网络设备支持的最高协议版本、需要终端设备上报的频段范围、以及网络设备功能项标志位。
终端设备110-1向网络设备120上报(3020)该终端设备的能力信息。终端设备的能力信息可以包括不同级别的能力。例如,终端设备的能力信息可以包括终端设备特定的能力。每个终端设备可以有不同的能力,这种终端设备能力适用于终端设备支持的所有载波和载波组合。在某些实施例中,终端设备的能力信息可以包括频段组合(Band Combination,BC)级别的终端设备能力。在其他实施例中,终端设备的能力信息也可以根据协议栈分层来上报。
上报的能力信息包括终端设备110-1支持的第一频段集合列表。仅为了解释说明的目的,在下文中,第一频段集合列表中包括的频段集合被称为“第一频段集合”。该第一频段集合列 表包括第一数目的第一频段集合。每个第一频段集合的指示信息包括第二数目的频段的索引、以及在频段之间切换的切换时间。上报的能力信息还包括终端设备110-1支持的第二频段集合列表。仅为了解释说明的目的,在下文中,第二频段集合列表中包括的频段集合被称为“第二频段集合”。该第二频段集合列表指示第三数目的第二频段集合。每个第二频段集合分别对应于多个连续的第一频段集合。第二频段集合中的频段由与该第二频段集合对应的多个连续的第一频段集合所包括的频段的索引指示。也就是说,每个第二频段集合的指示信息不包括频段的索引。换言之,第二频段集合列表包含的频段的索引在第一频段集合列表中对应的频段集合中。在某些实施例中,第一频段集合列表中包含的所有频段集合的指示信息均包含2个频段和一个切换时间。第一频段集合列表中的集合数量大于等于N*M,其中N大于等于3,其中M为第二频段集合列中的频段集合数量。第一频段集合列表中的第i*N+1到第(i+1)*N个频段集合对应于第二频段集合列中的第i+1个频段集合。第一频段集合列表中的第i*N+1到第(i+1)*N频段集合只包含N个频段,这N个频段为第二频段集合列中的第i+1个频段集合中的频段。
可以理解,第一频段集合列表以及第二频段集合列表可以是根据其他协议版本的频段集合列表。仅为了说明的目的,在本公开的实施例中,以根据R16的频段集合列表为例来描述第一频段集合列表,并且以根据R18的频段集合列表为例来描述第二频段集合列表。
如果终端设备110-1支持R18的频段集合,那么终端设备110-1也支持该频段集合回退的R16和/或R17的频段集合。仅作为示例,频段组合可以包含3个频段:频段A,频段B,频段C。可以理解,频段组合还可以包括其他数目的频段。支持R16但不支持R18的终端设备可以上报频段A+频段B,也可以上报频段A+频段C,可以不上报频段B+频段C。但是支持R18的终端设备如果支持频段A+频段B+频段C,那么终端设备能力中关于R16的频段集合的参数需要上报3个频段集合都支持,也就是频段A+频段B,频段A+频段C和频段B+频段C必须都支持。
在某些实施例中,第二频段集合可以包括3个频段。此时,第二频段集合对应3个第一频段集合。以下参照图4来描述本公开的某些实施例。如图4所示,上报的能力信息中第二频段集合列表中的频段集合的数量与第一频段集合列表中的频段集合的数量存在对应关系。第二频段集合列表(420)中的第一个频段集合对应于第一频段集合列表(410)中的前三个频段集合。在此情况下,该第一频段集合列表中的每个第一频段集合包括2个频段。此时,第一频段集合列表可以包括如下第一频段集合:频段A+频段B、频段B+频段C、频段A+频段C、以及频段C+频段D。如图4所示,第一频段集合列表中的第一频段集合的指示信息可以包括:频段A和频段B之间的切换时间为35us,频段B和频段C之间的切换时间为35us,频段A和频段C之间的切换时间为140us,以及频段C和频段D之间的切换时间为140us。第一频段集合列表中与第二频段集合列表存在对应关系的频段集合可以被排序在与第二频段集合列表不存在对应关系的频段集合之前。这里,存在对应关系的频段集合包含的频段是第二频段集合列表中的频段集合所包括的频段的子集。以此方式,减少了能力信息的上报量。
表4示出了第一频段集合列表的信元的示例。
表4
从表4可以看出,第一频段集合列表包括4个第一频段集合,并且每个第一频段集合包括2个频段。第一频段集合列表中的第一个频段集合的指示信息包括频段索引A和B,切换时间35us。第二个频段集合的指示信息包括频段索引B和C,切换时间35us。第三个频段集合的指示信息包括频段索引A和C,切换时间140us。第四个频段集合的指示信息包括频段索引C和D,切换时间140。
如图4所示,第二频段集合列表包括1个第二频段集合。该第二频段集合包括3个频段,频段A、频段B以及频段C。该第二频段集合对应于第一频段集合列表中的前3个频段集合,即,频段A+频段B、频段B+频段C、频段A+频段C。表5示出了第二频段集合列表的信元的示例。可以理解,表5中所示的信元只示出了频段索引和切换时间的相关信息,第二频段集合列表的信元还可以包括在表5中未示出的其他信息。
表5
从表5可以看出,第二频段集合列表包括1第二个频段集合。该第二频段集合的切换时间为140us。第二频段集合列表不包括该第二频段集合所包括的3个频段的索引。这3个频段由第一频段集合列表中与该第二频段集合对应的频段集合所包括的频段的索引指示。也就是说,这3个频段由第一频段集合列表中前3个频段集合包括的频段索引A、B和C来指示。以此方式,第二频段集合列表可以沿用第一频段集合列表中的频段索引,从而不用上报频段的索引,由此减少上报的能力信息中的信令。可以理解,图4、表4和表5中示出的频段集合数目、频段数据、频段索引以及切换时间均为示例性的,而非限制性的。
在其他实施例中,第二频段集合可以包括4个频段。此时,第二频段集合对应6个第一频段集合。在此情况下,第二频段集合列表中的位于第一个的频段集合可以对应于第一频段集合列表中的前六个频段集合。例如,第一频段集合列表可以包括如下频段第一集合:频段A+频段B、频段A+频段C、频段A+频段D、频段B+频段C、频段B+频段D、以及频段C+ 频段D。第二频段集合列表可以包括1个第二频段集合。该第二频段集合包括4个频段,频段A、频段B、频段C以及频段D。类似地,在这种情况下,第二频段集合列表不包括该第二频段集合所包括的4个频段的索引。这4个频段由第一频段集合列表中与该频段集合对应的频段集合所包括的频段的索引指示。也就是说,这4个频段由第一频段集合列表中的前6个频段集合包括的频段索引A、B、C和D来指示。
在另一些实施例中,第二频段集合列表中既存在包括3个频段的频段集合,又存在包括4个频段的频段集合,并且不同频段集合中的频段无重叠。在此情况下,第一频段集合列表中的第一频段集合可以以特定的顺序被排序。例如,作为示例,第二频段集合列表中位于第一个的第二频段集合包括3个频段,位于第二个的第二频段集合包括4个频段。在此情况下,在一些实施例中,在第一频段集合列表中,与上述位于第一个的第二集合对应的频段集合可以被排序在与上述位于第二个的第二频段集合对应的频段集合之前。作为另一个示例,第二频段集合列表中位于第一个的第二频段集合包括4个频段,位于第二个的第二频段集合包括3个频段。在此情况下,在一些实施例中,在第一频段集合列表中,与上述位于第一个的第二集合对应的频段集合可以被排序在与上述位于第二个的第二频段集合对应的频段集合之前。仅作为又一示例,第二频段集合列表中位于第一个的第二频段集合包括4个频段,位于第二个的第二频段集合包括3个频段,位于第三个的第二频段集合包括3个频段。在此情况下,在一些实施例中,在第一频段集合列表中,与上述位于第一个的第二集合对应的频段集合可以被排序在与上述位于第二个的第二频段集合对应的频段集合之前,并且与上述位于第二个的第二频段集合对应的频段集合被排序在与上述位于第三个的第二频段集合对应的频段集合之前。以此方式,减少了能力信息的上报量。
在某些实施例中,网络设备120可以根据第一频段集合列表中的频段集合的数目、频段索引以及第二频段集合列表中的频段集合的数目来确定终端设备110-1第二频段集合列表中的第二频段集合包括3个频段还是4个频段。例如,如果第二频段集合列表包括2个第二频段集合,且第一频段集合列表包括的频段集合的数目大于等于6小于9个,网络设备120可以确定第二频段集合列表所包括的2个第二频段集合支持3个频段。在其他实施例中,如果第二频段集合列表包括2个第二频段集合,且第一频段集合列表包括的频段集合的数目为9个,网络设备120可以确定(1)第二频段集合列表中的一个第二频段集合支持3个频段而另一个第二频段集合支持4个频段,或者(2)第二频段集合列表所包括的2个第二频段集合支持3个频段。网络设备120可以进一步根据第一频段集合列表中的频段集合所包括的频段索引来确定上述情况(1)或(2)。例如,网络设备120可以根据第一频段集合列表中连续的6个或连续的3个频段集合中的频段情况进行判断,例如,可以是以i*3为起点的连续的6个或连续的3个频段集合中的频段情况进行判断,i为自然数。例如,网络设备120可以根据前6个或前3个频段集合中的频段情况进行判断。作为示例,如果第一频段集合列表中的包括的频段集合为:频段A+频段B、频段B+频段C、频段A+频段C、频段D+频段E、频段E+频段F、频段F+频段D、频段H+频段J、频段J+频段K、频段G+频段K,则网络设备120可以确定第二频段集合列表包括两个包含3个频段的频段集合,即,频段A+频段B+频段C,频段D+频段E+频段F。作为另一示例,如果第一频段集合列表中的包括的频段集合为:频段A+频段B、频段A+频段C、频段A+频段D、频段B+频段C、频段B+频段D、频段C+频段D、频段G+频段E、频段E+频段F、频段F+频段G,则网络设备120可以确定第二频段集合列表包括一个包含4个频段的频段集合和另一个包含3个频段的频段集合,即,频段A+ 频段B+频段C+频段D,频段G+频段E+频段F。以此方式,减少了上报量。
在其他实施例中,上报的能力信息还可以包括第一指示。该第一指示用于指示在第一频段集合列表中与第二频段集合存在对应关系的频段集合的数目。这里,存在对应关系的频段集合包含的频段是第二频段集合列表中的频段集合所包括的频段的子集。例如,在某些实施例中,第一指示可以指示第一频段集合列表中的P个第一频段集合对应于第二频段集合列表中的第二频段集合。作为示例,如果第一频段集合列表有12个第一频段集合,P的值为9,第二频段集合列表中有2个频段集合,则第二频段集合列表包括一个包含4个频段的频段集合和另一个包含3个频段的频段集合。并且,如果第一频段集合列表中与包括4个频段的第二频段集合相关联的第一频段集合可以被排序在包括3个频段的第二频段集合相关联的第一频段集合之前,则网络设备120可以确定第二频段集合列表中位于第一个的第二频段集合包括4个频段,位于第二个的第二频段集合包括3个频段。在某些实施例中,第二频段集合列表中包括4个频段的第二频段集合被排序在包括3个频段的第二频段集合之前。在此情况下,如果第一频段集合列表有12个第一频段集合,P的值为9,第二频段集合列表中有2个频段集合,则第二频段集合列表包括一个包含4个频段的频段集合和另一个包含3个频段的频段集合,网络设备120可以确定第二频段集合列表中位于第一个的第二频段集合包括4个频段,位于第二个的第二频段集合包括3个频段。在此情况下,相应的第一频段集合列表中,前6个第一频段集合对应那个包含4个频段的频段集合,第7到第9个第一频段集合对应那个包含3个频段的频段集合。备选地,网络设备120可以根据第一频段集合列表中的第一频段集合所包括的频段来确定第二频段集合列表中的集合。例如,如果第一频段集合列表中的包括的频段集合为:如果是频段A+频段B、频段A+频段C、频段A+频段D、频段B+频段C、频段B+频段D、频段C+频段D、频段G+频段E、频段E+频段F、频段F+频段G,则网络设备120可以确定第二频段集合列中位于第一个的频段集合包含4个频段,位于第二个的频段集合包含3个频段,即,频段A+频段B+频段C+频段D,频段G+频段E+频段F。作为另一示例,如果第一频段集合列有12个第一频段集合,P的值为9,第二频段集合列表中有3个频段集合,则第二频段集合列表包括3个频段集合并且每个频段集合包含3个频段。
在某些实施例中,当第二频段集合列表中既存在包括3个频段的第二频段集合又存在包括4个频段的第二频段集合时,第一指示可以指示第一频段集合列表中的P个第一频段集合对应于第二频段集合列表中、包括3个频段的第二频段集合。这意味着第二频段集合列表中剩余的第二频段集合包括4个频段。作为示例,如果第一频段集合列表中有12个第一频段集合,P的值为3,第二频段集合列表中有2个频段集合,并且第一频段集合列表中与包括3个频段的第二频段集合相关联的第一频段集合被排序在包括4个频段的第二频段集合相关联的第一频段集合之前,则第一频段集合中的前3个第一频段集合与包括3个频段的第二频段集合相关联。由此,网络设备120可以确定第二频段集合列表中位于第一个的第二频段集合包括3个频段,位于第二个的第二频段集合包括6个频段。在此情况下,网络设备120还可以确定第一频段集合列表中余下3个的第一频段集合不与第二频段集合列表中的第二频段集合存在对应关系。反之亦然。即,当第二频段集合列表中既存在包括3个频段的第二频段集合又存在包括4个频段的第二频段集合时,第一指示可以指示第一频段集合列表中的P个第一频段集合对应于第二频段集合列表中、包括4个频段的第二频段集合。这意味着第二频段集合列表中剩余的第二频段集合包括3个频段。这样避免基站复杂的判断,有利于基站实现。
在又一些实施例中,第一指示可以指示第二频段集合列表中的第二频段集合的数量。例 如,第一指示可以指示第二频段集合列表中有Q个第二频段集合。作为示例,如果第一频段集合列有12个第一频段集合,Q的值为1,并且第一频段集合列表中与包括4个频段的第二频段集合相关联的第一频段集合可以被排序在包括3个频段的第二频段集合相关联的第一频段集合之前,则网络设备120可以确定第二频段集合列表中包括一个第二频段集合,并且该第二频段集合包括4个频段。备选地,在此情况下,如果第一频段集合列有12个第一频段集合,Q的值为1,并且终端设备不支持包括4个频段的第二频段集合,则网络设备120可以确定第二频段集合列表中包括一个第二频段集合,并且该第二频段集合包括3个频段。备选的,第一指示可以指示Q,Q可以表示第二频段集合列表中包括3个频段的第二频段集合的数量,或包括4个频段的第二频段集合的数量。例如,当第二频段集合列表中既可能存在包括3个频段的第二频段集合又可能存在包括4个频段的第二频段集合时,若Q表示包括4个频段的第二频段集合的数量,且第二频段集合列表中有两个第二频段集合,Q的值为1,则网络设备120就能确定第二频段集合列表中第一个第二频段集合为包含4个频段的第二频段集合,第二个第二频段集合为包含3个频段的第二频段集合。进一步的,网络设备120可以确定第一频段集合列表中前6个第一频段集合对应第一个第二频段集合,第7到第9个第一频段集合对应第二个第二频段集合。这样便于基站判断终端设备的上报情况,简化基站实现。
备选地,第一指示可以指示第一频段集合列表中的P个第一频段集合对应于第二频段集合列表中的Q个第二频段集合。作为另一个示例,如果第一频段集合列表中有12个第一频段集合,P的值为6,第二频段集合列表中有至少2个频段集合,Q的值为1,则第一频段集合中的前6个第一频段集合与包括4个频段的第二频段集合相关联。由此,网络设备120可以确定第二频段集合列表中位于第一个的第二频段集合包括4个频段,其余的第二频段集合包括3个频段。这意味着第二频段集合列表中剩余的第二频段集合包括3个频段。这样避免基站复杂的判断,有利于基站实现。
在某些实施例中,第一频段集合所在的频段组合可以作为第二频段集合。换言之,第一频段集合相关联的频段组合可以作为第二频段集合。这里,频段集合与频段组合相关联可以意味着该频段集合属于该频段组合。在此情况下,终端设备110-1上报的能力信息中的频段组合可以包括第二指示信息,以用于指示该频段组合是否支持第二频段集合列表。这样减少了上报量。
第二频段集合的指示信息还可以包括频段之间的切换时间。在某些实施例中,第二频段集合的指示信息包括第一切换时间。该第一切换时间用于该第二频段集合中的所有频段之间的切换。仅作为示例,如果该第二频段集合包括频段A、频段B和频段C,并且第一切换时间为140us,则终端设备110-1将140us应用到频段A和频段B之间、频段A和频段C之间、以及频段B和频段C之间的切换。可选地,在此情况下,如果终端设备110-1在频段A、频段B和频段C之间进行切换,则终端设备110-1将140us应用到上述三个频段之间的切换。在另一些实施例中,如果第一频段集合列表中与该第二频段集合对应的多个连续的第一频段集合中存在小于第一切换时间的切换时间,则终端设备110-1可以对相应的频段应用该切换时间。例如,该第二频段集合对应于第一频段集合列表中的3个第一频段集合:频段A+频段B、频段B+频段C、频段A+频段C。第一频段集合的指示信息还包括:频段A和频段B之间的切换时间为35us、频段B和频段C之间的切换时间为35us、频段A和频段C之间的切换时间为210us。在此情况下,终端设备110-1可以将35us应用到频段A和频段B之间的切换,将35us应用到频段B和频段C之间的切换,以及将140us(即,第一切换时间)应用到 频段A和频段C之间的切换。可选地,在此情况下,如果终端设备110-1在频段A、频段B和频段C之间进行切换,则终端设备110-1将140us应用到上述三个频段之间的切换。以此方式,减少了能力信息的上报量。
在其他实施例中,第二频段集合的指示信息包括多个切换时间。该多个切换时间分别用于该第二频段集合包括的任意两个频段之间的切换。该多个切换时间中的任何两个切换时间对应的切换频段中的至少一个频段不同。仅作为示例,如果该第二频段集合包括频段A、频段B和频段C,并且多个切换时间分别为35us、140us和210us,则终端设备110-1可以将35us应用到频段A和频段B之间的切换,将140us应用到频段A和频段C之间的切换,以及将210us应用到频段B和频段C之间的切换。备选地,如果终端设备110-1在频段A、频段B和频段C之间进行切换,则终端设备110-1将210us应用到上述三个频段之间的切换。可以理解,上述切换时间和第二频段集合的对应关系仅为示例性的,而非限制性的。在某些实施例中,网络设备120可以向终端设备110-1发送(3040)配置。该配置指示上述多个切换时间中的一个或多个。在此情况下,终端设备110-1可以基于该配置来从上述多个切换时间确定所指示的一个或多个切换时间。备选地,终端设备110-1还可以基于预先确定的配置来从上述多个切换时间确定所指示的一个或多个切换时间。例如,如果预先确定的配置指示采用时间最长的切换时间并且上述多个切换时间包括35us、140us和210us,则终端设备110-1可以将210us应用到频段之间的切换。应注意,实际调度或者配置时预留的切换时间或准备时间不能超过终端设备能力。以此方式,当射频链在不同频段之间切换时,终端设备110-1可以采用更短的切换时间。不会因为其他载波激活/去激活,增加或释放,而改变射频链的切换时长。
在另一些实施例中,如果第二频段集合的指示信息不包括切换时间信息,则网络设备120可以确定第一频段集合列表中与该第二频段集合对应的多个连续的第一频段集合中的最长切换时间用于该第二频段集合包括的频段之间的切换。换言之,终端设备110-1在第二频段集合的指示信息中不上报切换时间,并且隐式地指示第一频段集合列表种上报的最长切换时间用于该频段集合包括的频段之间的切换。仅作为示例,该第二频段集合包括频段A、频段B和频段C,并且该第二频段集合对应于第一频段集合列表中的3个第一频段集合:频段A+频段B、频段B+频段C、频段A+频段C。第一频段集合的指示信息还包括:频段A和频段B之间的切换时间为35us、频段B和频段C之间的切换时间为35us、频段A和频段C之间的切换时间为140us。在此情况下,终端设备110-1将140us应用到频段A和频段B之间、频段A和频段C之间、以及频段B和频段C之间的切换。可选地,在此情况下,如果终端设备110-1在频段A、频段B和频段C之间进行切换,则终端设备110-1将140us应用到上述三个频段之间的切换。这样减少了上报量,降低了调度复杂度。
在其他实施例中,如果第二频段集合的指示信息不包括切换时间信息,则网络设备120可以确定第一频段集合列表中与该第二频段集合对应的多个连续的第一频段集合中的多个切换时间分别用于该第二频段集合包括的对应的两个频段之间的切换。换言之,终端设备110-1在第二频段集合的指示信息中不上报切换时间,并且隐式地指示复用第一频段集合列表中的切换时间。仅作为示例,该第二频段集合包括频段A、频段B和频段C,并且该第二频段集合对应于第一频段集合列表中的3个频段集合:频段A+频段B、频段B+频段C、频段A+频段C。第一频段集合的指示信息还包括:频段A和频段B之间的切换时间为35us、频段B和频段C之间的切换时间为35us、频段A和频段C之间的切换时间为140us。在此情况下,终 端设备110-1可以将35us应用到频段A和频段B之间的切换,将140us应用到频段A和频段C之间的切换,以及将35us应用到在频段B和频段C之间的切换。可选地,在此情况下,如果终端设备110-1在频段A、频段B和频段C之间进行切换,则终端设备110-1将最长的切换时间(即,140us)应用到上述三个频段之间的切换。这样减少了上报量,使得终端可以采用更短的切换时间。
在其他实施例中,第二频段集合列表中的第二频段集合内的频段可以被分组。在此情况下,终端设备110-1可以在第二频段集合的指示信息中上报两个切换时间,一个用于分组内的频段之间切换(即,第二切换时间),另一个用于组间的频段之间切换(即,第三切换时间)。仅作为示例,该第二频段集合包括频段A、频段B和频段C,并且频段A和频段B被分到一组。第二切换时间为35us,第三切换时间为140us。在此情况下,终端设备110-1可以将35us应用到频段A和频段B之间的切换,将140us应用到射频链在频段A和频段C之间以及频段B和频段C之间的切换。减少了切换时间上报量。
在某些实施例中,第二频段集合的指示信息还可以包括上行射频链切换期间第六频段上的下行中断情况。第六频段为第二频段集合所在频段组合的频段。下行中断情况可以指示在上行切换期间,第六频段是否会产生下行中断。在其他实施例中,第二频段集合的指示信息也可以不上报下行中断情况。在此情况下,第一频段集合列表中的第一频段集合的指示信息中的下行中断情况可以被沿用。在某些实施例中,如果上报第二频段集合的终端设备在切换时只涉及两个频段,则对应的第一频段集合的指示信息中的下行中断情况可以被沿用。例如,第二频段集合列表中的第二频段集合包括频段A+频段B,并且第二频段集合的指示信息不包括下行中断情况,该第二频段集合对应的第一频段集合列表中的第一频段集合包括频段A+频段B,第一频段集合的指示信息指示在第六频段上不产生下行中断,。在此情况下,网络设备120可以确定终端设备110-1根据第二频段集合在频段A和频段B之间进行切换时,第六频段上没有下行中断。在另一些实施例中,如果上报第二频段集合的终端设备在切换时涉及三个或三个以上频段,则与该第二频段集合对应的多个第一频段集合的指示信息中的下行中断情况可以被沿用。如果这些个第一频段集合的指示信息中至少一个指示在第六频段上产生下行中断,则网络设备120可以确定终端设备110-1在频段A、频段B和频段C之间进行切换时,在第六频段上存在下行中断。作为示例,第二频段集合包括频段A、频段B和频段C。该第二频段集合对应于第一频段集合列表中的3个第一频段集合:频段A+频段B、频段B+频段C、频段A+频段C。第一频段集合的指示信息还包括:频段A和频段B之间的切换在频段A、B和C上都没有下行中断、频段B和频段C之间的切换在频段A、B和C上都没有下行中断、频段A和频段C之间的切换在频段A、B和C上都没有下行中断。在此情况下,网络设备120可以确定终端设备110-1在频段A、频段B和频段C之间进行切换时,在频段A、B和C上都不存在下行中断。作为另一示例,如果第一频段集合的指示信息还包括:频段A和频段B之间的切换在频段A、B和C上都没有下行中断、频段B和频段C之间的切换在频段A、B和C上都没有下行中断、频段A和频段C之间的切换在频段C上有下行中断,则网络设备120可以确定终端设备110-1在频段A、频段B和频段C之间进行切换时,在频段C上存在下行中断,在频段A和频段B上不产生下行中断。
终端设备110-1上报的能力信息还可以包括与第一频段集合列表相关联的第一频段组合列表以及与第二频段集合相关联的第二频段组合列表。仅为了解释说明的目的,在下文中,第一频段组合列表中包括的频段集合被称为“第一频段组合”,第二频段组合列表中包括的频 段集合被称为“第二频段组合”。该第一频段组合列表指示第五数目的第一频段组合,并且该第二频段组合列表指示第六数目的第二频段组合。第二频段组合列表中的第二频段组合与第一频段组合列表中的一个或多个频段组合存在对应关系。这里,第一频段组合中存在对应关系的第一频段组合包含的频段是第二频段组合列表中的第二频段组合所包括的频段的子集或全部。在某些实施例中,该第二频段组合列表中包括的每个第二频段组合所包括的频段为与该第二频段组合对应的一个或多个连续的第一频段组合所包括的频段。仅作为示例,如果第一频段组合列表中的频段组合包含频段A+频段B+频段D,频段A+频段C+频段D,频段B+频段C+频段D,第二频段组合列表只包含一个频段组合,并且该频段组合与上述多个频段组合存在对应关系。此时,第二频段组合列表中的该频段组合包含的频段为上述多个频段组合所包含的频段,即,频段A+频段B+频段C+频段D。每个第二频段组合的指示信息不包括频段的索引。换言之,第二频段组合列表包含的频段的索引在第一频段组合列表中对应的频段组合中。
在某些实施中,第一频段组合列表中的第一频段组合与第二频段组合列表中的第二频段组合可以是一一对应的,即第五数目等于第六数目。在此情况下,如果第一频段组合列表中的一个或多个第一频段组合在第二频段组合列表中不支持,则对应的第二频段集合列表可以为空。备选地,对应的第二频段组合列表中的至少一个域可以为空,例如可以为切换模式为空和/或下行中断字段为空和/或功率提升字段为空。以此方式,终端设备以比较简单的方式进行能力信息的上报,降低终端设备实现复杂度。
在某些实施例中,第一频段组合列表中包括3个第一频段组合:频段A+频段B、频段B+频段C和频段C+频段D,而第一频段组合列表中并不支持上报频段A+频段B+频段C。如果终端设备110-1支持在3个频段上支持射频链的切换,则第二频段组合列表中可以包括一个第二频段组合:频段A+频段B+频段C,并且该第二频段组合的指示信息不包括频段的索引,即,不包括频段索引A、B和C。第二频段组合列表包含的频段的索引在第一频段组合列表中对应的频段组合中。此时,第一频段组合列表中的第一频段组合与第二频段组合列表中的第二频段组合的对应关系可以是一对N的关系,即第五数目大于第六数目。例如,第一频段组合列表中的第一频段组合的数目可以是第二频段组合列表中的第二频段组合的数目的N倍。例如,第二频段组合列表中的第k个第二频段组合对应于第一个频段组合列表中的第(k-1)*N+1到k*N的第一频段组合,第一个频段组合列表中的第K*N+1个及之后的第一频段组合不与第二频段组合列表相对应,这里K为第二频段组合列表中的第二频段组合的数量。在某些实施例中,第一频段组合列表中与第二频段组合列表存在对应关系的(相关联的)频段组合可以被排序在与第二频段组合列表不存在对应关系的频段组合之前。备选地,第一频段组合列表中与第二频段组合列表存在对应关系的频段组合可以被排序在与第二频段组合列表不存在对应关系的频段组合之后。例如,如果第二频段组合列表中第二频段组合的数量为K,第一频段组合列表中第一频段组合的数量为L,并且第k个第二频段组合对应于第一个频段组合列表中的第L-(K-k+1)*N+1到L-(K-k)*N的第一频段组合,则第一个频段组合列表中的第L-(K-k+1)*N个及之前的第一频段组合不与第二频段组合列表相对应。以此方式,第二频段组合不用上报频段索引,减少了第二频段组合的上报量。
在另一些实施例中,第二频段组合列表中的第二频段组合可以对应于第一频段组合列表中的N个第一频段组合,第二频段组合列表中的第二频段组合还可以对应于第一频段组合列表中的M个第一频段组合。仅作为示例,第二段组合列表中的第二频段组合可以对应于第一 频段组合列表中的3个第一频段组合,第二频段组合列表中的第二频段组合还可以对应于第一频段组合列表中的4个第一频段组合。在某些实施例中,网络设备120可以根据第一频段组合列表中的第一频段组合的数目以及第二频段组合列表中的第二频段组合的数目来确定终端设备110-1第二频段组合列表中的频段信息。作为示例,如果第一频段组合列表有6个第一频段组合,第二频段组合列表中有1个第二频段组合,并且第一频段组合列表中包括的频段组合为:频段A+频段B、频段A+频段C、频段B+频段C、频段B+频段D、频段C+频段D,频段D+频段E,则网络设备120可以确定第二频段集合列表包括1个第二频段组合为频段A+频段B+频段C。以此方式,第二频段组合不用上报频段索引,从而减少了第二频段组合的上报量。
在另外的实施例中,终端设备110-1上报的能力信息可以包括第三指示。该第三指示用于指示在第一频段组合列表中与第二频段组合存在对应关系的频段组合的数目。这里,存在对应关系的第一频段组合包含的频段是第二频段组合列表中的第二频段组合所包括的频段的子集或全部。备选的,第三指示可以用于指示在第二频段组合列表中与第一频段组合存在对应关系的频段组合的数目。备选的,第三指示可以用于指示在第一频段组合列表中的X个第一频段组合与第二频段组合中Y个第二频段组合存在对应关系。以此方式,能力信息中的第二频段组合不用上报频段索引,减少了第二频段组合的上报量。
在其他实施例中,第一频段组合列表中的第一频段组合与第二频段组合列表中的第二频段组合可以是一一对应的,第二频段组合列表中的第二频段组合也可以对应于第一频段组合列表中的N个第一频段组合。此时,第一频段组合列表中的第一频段组合可以以特定的顺序被排序。例如,在第一频段组合列表中,与第二频段组合列表中的第二频段组合一一对应的第一频段组合可以被排序在与第二频段组合列表中的第二频段组合多一对应的第一频段组合之前。备选地,在第一频段组合列表中,与第二频段组合列表中的第二频段组合一一对应的第一频段组合可以被排序在与第二频段组合列表中的第二频段组合多一对应的第一频段组合之后。此时,终端设备110-1上报的能力信息中的第三指示可以指示第一频段组合列表中的第一频段组合哪些频段组合是一对一,哪些是多对一,或者哪些是不对应的。仅作为示例,如果第三指示包括N和M两个数字,则N可以指示前N个第一频段频段组合与第二频段组合是一一对应的,M可以指示随后的M个第一频段组合与第二频段组合是多一对应的。例如,如果第一频段组合列表包括4个第一频段组合,N的值为1,M的值为3,第二频段组合列表中有两个频段组合,则网络设备120可以确定第一频段组合列表中的位于第一位的第一频段组合与第二频段组合是一一对应的,第二至四个第一频段组合与第二频段组合是多一对应的。在此情况下,仅作为示例,如果第一频段组合列表包括如下频段组合:频段E+频段F+频段G、频段A+频段B、频段A+频段C、频段B+频段C,则第二频段组合列表包括两个频段组合,即,频段E+频段F+频段G和频段A+频段B+频段C。以此方式,能力信息中的第二频段组合不用上报具体的频段索引,减少了第二频段组合的上报量。
作为另一示例,终端设备110-1上报的能力信息中的第三指示可以指示第二频段组合列表中的第二频段组合哪些频段组合是一对一,哪些是一对多。仅作为示例,如果第三指示包括P和Q两个数字,则P可以指示前P个第二频段组合与第一频段组合是一一对应的,Q可以指示随后的Q个第二频段组合与第一频段组合是一多对应的。例如,如果第一频段组合列表包括4个第一频段组合,P的值为1,Q的值为1,则网络设备120可以确定第二频段组合列表中的位于第一位的第二频段组合与第一频段组合是一一对应的,位于第二位的第二频段 组合与第一频段组合是一多对应的。在此情况下,仅作为示例,如果第一频段组合列表包括如下频段组合:频段E+频段F+频段G、频段A+频段B、频段A+频段C、频段B+频段C,则第二频段组合列表包括两个频段组合,即,频段E+频段F+频段G和频段A+频段B+频段C。以此方式,第二频段组合不用上报频段索引,减少了第二频段组合的上报量。
在其他实施例中,第三指示可以用于指示在第一频段组合列表中的X个第一频段组合与第二频段组合中Y个第二频段组合存在对应关系。作为示例,如果第一频段组合列表包括4个第一频段组合,X的值为3,Y的值为1,则网络设备120可以确定第一频段组合列表中的第一至第三个第一频段组合与第二频段组合列表中的第一个第二频段组合是对应的。可选的,余下的第二频段组合与第一频段组合的对应关系可以由包括在能力信息中的X2和Y2的值提供或者是一对一的关系。例如,X2个第一频段组合与余下的第二频段组合中Y2个第一频段组合存在对应关系。以此方式,不用在第二频段组合列表中上报频段的索引,从而减少了能力信息的上报量。
在某些实施例中,第二频段组合所包括的频段集合包括与第二频段组合对应的一个或多个连续的第一频段组合所包括的频段集合。例如,第二频段组合列表中的第二频段组合与第一频段组合列表中N个第一频段组合对应,则第二频段组合的第i个频段集合分别对应上述N个第一频段组合中的第i个频段集合。换言之,第i个频段集合中的频段为N个第一频段组合中的第i个频段集合中的频段。如果终端设备110-1上报第一频段组合列表中的频段组合包含频段A+频段B,频段A+频段C,频段B+频段C,这三个频段组合中包含的频段集合分别为,频段A+频段B,频段A+频段C,频段B+频段C。第二频段组合列表只包含一个频段组合,这个频段组合对应第一频段组合列表中前3个第一频段组合。此时,第二频段组合列表中的该频段组合包含的频段为频段A+频段B+频段C,该频段组合中的频段集合包括的频段为A+频段B+频段C,并且该频段组合的指示信息不包括这些频段的索引。以此方式,减少能力信息上报量。
在其他实施例中,如果终端设备110-1在第一频段组合列表中的第三频段组合包含第三频段、第四频段和第五频段,并且终端设备110-1在第二频段组合列表中支持第三频段、第四频段、第五频段之间的切换,则该第三频段组的指示信息合包括第三频段的索引、第四频段的索引、第五频段的索引。第三频段组合对应的至少一组特征集合参数中第五频段对应的MIMO层数为零。本文中使用的术语“MIMO层数”可以指代空间同时传输的数据流的数目。换句话说,允许支持R18的终端设备110-1上报的频段组合对应的特征集合参数中部分频段对应的最大MIMO层数为0。例如,如果终端设备110-1在R16上报支持频段A+频段B之间动态切换但不支持此时上报的频段组合为频段A+频段B+频段C,也就是说不支持在A+B之间动态切换时还支持频段C传输,在R18上报支持频段A+频段B+频段C之间动态切换,那么终端设备110-1可以在R16上报支持的频段组合包括频段A+频段B+频段C,这样R16的频段组合和R18的频段组合就可以一一对应了。此时,在R16的频段组合对应的特征集合参数中至少一组参数中频段C对应的MIMO层数0。例如,R16的频段组合对应的特征集合参数中的MIMO层数可以包括以下一组或多个组1+2+0,或2+2+0,或2+1+0,以此表示终端设备110-1不同时支持频段A+频段B+频段C。在R18的频段组合对应的特征集合参数中有一组参数为MIMO层数为2+2+2,或1+2+2,或2+1+1(或者其他2和或1的组合),以此表示终端设备110-1支持在频段A+B+C上进行动态切换。以此方式,终端设备以更简单的方式进行能力信息的上报,降低UE实现复杂度。
图5给出了一种示例的通信方法500的流程的示意图。方法500实现在终端设备处,例如,终端设备110-1。
在某些实施例中,终端设备110-1从网络设备120接收针对该终端设备能力查询的请求。在接收到上述请求后,终端设备110-1可以解析该请求以获得终端设备能力上报需求信息。例如,针对该终端设备能力查询的请求可以包括用于指示终端设备110-1网络设备230想知道哪些终端设备能力。终端设备能力上报需求信息还可以包括以下一项或多项:网络设备支持的最高协议版本、需要终端设备上报的频段范围、以及网络设备功能项标志位。
在框510处,终端设备110-1向网络设备120上报该终端设备的能力信息。终端设备的能力信息可以包括不同级别的能力。例如,终端设备的能力信息可以包括终端设备特定的能力。每个终端设备可以有不同的能力,这种终端设备能力适用于终端设备支持的所有载波和载波组合。在某些实施例中,终端设备的能力信息可以包括频段组合(Band Combination,BC)级别的终端设备能力。在其他实施例中,终端设备的能力信息也可以根据协议栈分层来上报。
上报的能力信息包括终端设备110-1支持的第一频段集合列表。该第一频段集合列表包括第一数目的第一频段集合。每个第一频段集合的指示信息包括第二数目的频段的索引、以及在频段之间切换的切换时间。上报的能力信息还包括终端设备110-1支持的第二频段集合列表。该第二频段集合列表指示第三数目的第二频段集合。每个第二频段集合分别对应于多个连续的第一频段集合。第二频段集合中的频段由与该第二频段集合对应的多个连续的第一频段集合所包括的频段的索引指示。也就是说,每个第二频段集合的指示信息不包括频段的索引。换言之,第二频段集合列表包含的频段的索引在第一频段集合列表中对应的频段集合中。在某些实施例中,第一频段集合列表中包含的所有频段集合的指示信息均包含2个频段和一个切换时间。第一频段集合列表中的集合数量大于等于N*M,其中N大于等于3,其中M为第二频段集合列中的频段集合数量。第一频段集合列表中的第i*N+1到第(i+1)*N个频段集合对应于第二频段集合列中的第i+1个频段集合。第一频段集合列表中的第i*N+1到第(i+1)*N频段集合只包含N个频段,这N个频段为第二频段集合列中的第i+1个频段集合中的频段。已经参照图3描述了第一频段集合列表和第二频段集合列表,为了简要的目的,在此不再赘述。
终端设备110-1上报的能力信息中的第二频段集合的指示信息还可以包括针对每个频段集合的频段之间的切换时间。在某些实施例中,第二频段集合的指示信息包括第一切换时间。该第一切换时间用于该第二频段集合中的所有频段之间的切换。在其他实施例中,第二频段集合的指示信息包括多个切换时间。该多个切换时间分别用于该第二频段集合包括的任意两个频段之间的切换。该多个切换时间中的任何两个切换时间对应的切换频段中的至少一个频段不同。
在某些实施例中,在框520处,终端设备110-1可以从网络设备120接收配置。该配置指示上述多个切换时间中的一个或多个。在此情况下,终端设备110-1可以基于该配置来从上述多个切换时间确定所指示的一个或多个切换时间。备选地,终端设备110-1还可以基于预先确定的配置来从上述多个切换时间确定所指示的一个或多个切换时间。例如,预先确定的配置可以指示采用时间最长的切换时间。应注意,实际调度或者配置时预留的切换时间或准备时间不能超过终端设备能力。以此方式,当射频链在不同频段之间切换时,终端设备110-1可以采用更短的切换时间。不会因为其他载波激活/去激活,增加或释放,而改变射频链的切 换时长。在另一些实施例中,第二频段集合的指示信息不包括切换时间信息。在其他实施例中,第二频段集合列表中的第二频段集合内的频段可以被分组。在此情况下,终端设备110-1可以在第二频段集合的指示信息中上报两个切换时间,一个用于分组内的频段之间切换(即,第二切换时间),另一个用于组间的频段之间切换(即,第三切换时间)。已经参照图3描述了切换时间,为了简要的目的,在此不再赘述。
终端设备110-1上报的能力信息还可以包括与第一频段集合列表相关联的第一频段组合列表以及与第二频段集合相关联的第二频段组合列表。该第一频段组合列表包括第五数目的第一频段组合,并且该第二频段组合列表包括第六数目的第二频段组合。第二频段组合列表中的第二频段组合与第一频段组合列表中的一个或多个频段组合存在对应关系。这里,第一频段组合中存在对应关系的第一频段组合包含的频段是第二频段组合列表中的第二频段组合所包括的频段的子集或全部。在某些实施例中,该第二频段组合列表中包括的每个第二频段组合所包括的频段为与该第二频段组合对应的一个或多个连续的第一频段组合所包括的频段。在某些实施中,第一频段组合列表中的第一频段组合与第二频段组合列表中的第二频段组合可以是一一对应的,即第五数目等于第六数目。在某些实施中,第一频段组合列表中的第一频段组合与第二频段组合列表中的第二频段组合的对应关系可以是一对N的关系,即第五数目大于第六数目。已经参照图3描述了第一频段组合列表和第二频段组合列表,为了简要的目的,在此不再赘述。
图6给出了一种示例的通信方法600的流程的示意图。方法600实现在网络设备处,例如,网络设备120。
在某些实施例中,网络设备120向终端设备110-1发送针对该终端设备能力查询的请求。针对该终端设备能力查询的请求可以包括用于指示终端设备110-1网络设备230想知道哪些终端设备能力。终端设备能力上报需求信息还可以包括以下一项或多项:网络设备支持的最高协议版本、需要终端设备上报的频段范围、以及网络设备功能项标志位。
在框610处,网络设备120从终端设备110-1接收该终端设备的能力信息。终端设备的能力信息可以包括不同级别的能力。例如,终端设备的能力信息可以包括终端设备特定的能力。每个终端设备可以有不同的能力,这种终端设备能力适用于终端设备支持的所有载波和载波组合。在某些实施例中,终端设备的能力信息可以包括频段组合(Band Combination,BC)级别的终端设备能力。在其他实施例中,终端设备的能力信息也可以根据协议栈分层来上报。
上报的能力信息包括终端设备110-1支持的第一频段集合列表。该第一频段集合列表包括第一数目的第一频段集合。每个第一频段集合的指示信息包括第二数目的频段的索引、以及在频段之间切换的切换时间。上报的能力信息还包括终端设备110-1支持的第二频段集合列表。该第二频段集合列表指示第三数目的第二频段集合。每个第二频段集合分别对应于多个连续的第一频段集合。第二频段集合中的频段由与该第二频段集合对应的多个连续的第一频段集合所包括的频段的索引指示。也就是说,每个第二频段集合的指示信息不包括频段的索引。换言之,第二频段集合列表包含的频段的索引在第一频段集合列表中对应的频段集合中。在某些实施例中,第一频段集合列表中包含的所有频段集合的指示信息均包含2个频段和一个切换时间。第一频段集合列表中的集合数量大于等于N*M,其中N大于等于3,其中M为第二频段集合列中的频段集合数量。第一频段集合列表中的第i*N+1到第(i+1)*N个频段集合对应于第二频段集合列中的第i+1个频段集合。第一频段集合列表中的第i*N+1到第 (i+1)*N频段集合只包含N个频段,这N个频段为第二频段集合列中的第i+1个频段集合中的频段。已经参照图3描述了第一频段集合列表和第二频段集合列表,为了简要的目的,在此不再赘述。
终端设备110-1上报的能力信息中的第二频段集合的指示信息还可以包括针对每个频段集合的频段之间的切换时间。在某些实施例中,第二频段集合的指示信息包括第一切换时间。该第一切换时间用于该第二频段集合中的所有频段之间的切换。在其他实施例中,第二频段集合的指示信息包括多个切换时间。该多个切换时间分别用于该第二频段集合包括的任意两个频段之间的切换。该多个切换时间中的任何两个切换时间对应的切换频段中的至少一个频段不同。
在某些实施例中,在框620处,网络设备120可以向终端设备110-1发送配置。该配置指示上述多个切换时间中的一个或多个。在此情况下,终端设备110-1可以基于该配置来从上述多个切换时间确定所指示的一个或多个切换时间。应注意,实际调度或者配置时预留的切换时间或准备时间不能超过终端设备能力。以此方式,当射频链在不同频段之间切换时,终端设备110-1可以采用更短的切换时间。不会因为其他载波激活/去激活,增加或释放,而改变射频链的切换时长。
在另一些实施例中,如果第二频段集合的指示信息不包括切换时间信息,则网络设备120可以确定第一频段集合列表中与该第二频段集合对应的多个连续的频第一段集合中的最长切换时间用于该第二频段集合包括的频段之间的切换。换言之,终端设备110-1在第二频段集合的指示信息中不上报切换时间,并且隐式地指示第一频段集合列表种上报的最长切换时间用于该频段集合包括的频段之间的切换。在其他实施例中,如果第二频段集合的指示信息不包括切换时间信息,则网络设备120可以确定第一频段集合列表中与该第二频段集合对应的多个连续的第一频段集合中的多个切换时间分别用于该第二频段集合包括的对应的两个频段之间的切换。换言之,终端设备110-1在第二频段集合的指示信息中不上报切换时间,并且隐式地指示复用第一频段集合列表中的切换时间。在其他实施例中,第二频段集合列表中的第二频段集合内的频段可以被分组。在此情况下,终端设备110-1可以在第二频段集合的指示信息中上报两个切换时间,一个用于分组内的频段之间切换(即,第二切换时间),另一个用于组间的频段之间切换(即,第三切换时间)。已经参照图3描述了切换时间,为了简要的目的,在此不再赘述。
