- the priority is configured such that the priority of band D is higher than the priority of band A, the priority of band A is higher than the priority of band C, and the priority of band C is higher than the priority of band B (simply described as D>A>C>B), then referring to the definition of criterion 1, since band D has the highest priority, switch from band (i.e., band A and C) is selected as the switching period location. In this case, the information transmission on band A and band C with higher priority is interrupted, while the information transmission on band B with the lowest priority is protected. Band D, which does not transmit data at all, is also protected.

- band D the frequency band pairs involved are band pair 1: A ⁇ B, band pair 2: A ⁇ D.
- the priority is configured as D>A>B, then referring to the definition of criterion 1, since band D has the highest priority, switch from band (i.e. band A) is selected as the switching period location. In this case, the information transmission on A with a higher priority is also interrupted, while the information transmission on B with the lowest priority is protected, and band D, which does not transmit data at all, is also protected, so the spectrum efficiency is low.
- the priority of the frequency domain resources can be used to determine the location of the switching time.
- the specific determination method can be referred to the description in the subsequent embodiments, which will not be repeated here.
- the priority of the frequency domain resources can also be understood as any of the following descriptions: the transmission priority of the information on the frequency domain resources, or the priority of the transmission on the protection frequency domain resources, or the priority of setting the switching time for the frequency domain resources that are not located, or the priority of the frequency domain resources that are not located for the switching time.
- band pair 1 A ⁇ B
- band pair 2 C ⁇ D. If the priority is configured as A>B>D>C (or A>D>B>C), then referring to the definition of criterion 1, since band A has the highest priority, switch to bands (i.e., bands B and D) is selected as the switching period location. In this case, the information transmission of band D with a higher priority is also interrupted, while the information transmission on band C with the lowest priority is protected, so the spectrum efficiency is low.

- the frequency domain resources where the length of the time (such as symbol) that is not scheduled for information transmission on a time unit (such as a time slot) is greater than or equal to the duration of the switching time are third frequency domain resources. It is understandable that since there is no valid transmission on the associated frequency domain resources, or it is described as empty symbols on a time slot of the associated frequency domain resources, or it is described as no information transmission on the associated frequency domain resources, therefore, the associated frequency domain resources are actually a special third frequency domain resource, that is, the associated frequency domain resources also meet the condition 3 as the third frequency domain resources.

- the time difference where no uplink transmission is required or no uplink transmission is performed can be understood as an idle symbol.
- criterion 2 a new criterion is proposed for determining the switching period location for switching between three or more bands, which is referred to as criterion 2 below.
- the description of criterion 2 is as follows:
- the UE determines the switching period location as: the switching-from band(s) or switching-to band(s) where the band with the highest priority is located, except for the associated band. It can also be understood that when determining the frequency domain resource with the highest priority from the frequency domain resources involved in the switching, the associated band is not regarded as the frequency domain resource involved in the switching, or the associated band is not taken into consideration for determination. Then, based on the determined frequency domain resource with the highest priority, the frequency domain resource where the switching time is located is further determined to be the pre-switching frequency domain resource or the post-switching frequency domain resource where the frequency domain resource with the highest priority is located. It should be understood that non-associated frequency domain resources are frequency domain resources other than associated frequency domain resources.

Then, based on the determined frequency domain resource with the highest priority, the frequency domain resource where the switching time is located is further determined as the pre-switching frequency domain resource or the post-switching frequency domain resource where the frequency domain resource with the highest priority is not located.
- the frequency domain resources involved in the switching are a set of at least one first frequency domain resource and at least one second frequency domain resource.
- the UE determines the switching period location on either switching-from band(s) or switching-to band(s)that is involved in the UL Tx switching and is not with the highest priority band except the associated band/the band wherein the switching period will not interrupt the UL transmission in this band.
- the switching time will not interrupt the uplink transmission on the band, which can also be described as the switching time will not affect the uplink transmission on the band.
- the description of criterion 2 can also be: when involving associated bands, if the associated band has the highest priority, it should be excluded when determining the switching period location, that is, the associated band should be excluded from the frequency bands involved in the uplink switching.
- an associated band when it is involved, it should be excluded when determining the switching period location, that is, the associated band should be excluded from the frequency bands involved in uplink switching.
- the frequency domain resources involved in the switching are a set of at least one first frequency domain resource and at least one second frequency domain resource.
- the description of criterion 2 may also be: when the priority of the associated band is the highest, it should be excluded from the frequency domain resource band list involved in the switching to determine the switching period location as switching-from band(s) or switching-to band(s). And/or, when the priority of "frequency domain resources whose information transmission will not be affected by the switching time" is the highest, it should be excluded from the frequency domain resource list involved in the switching to determine the switching period location as switching-from band(s) or switching-to band(s).
- the associated band/the band wherein the switching period will not interrupt the UL transmission in this band is of highest priority, it should be excluded from the band list for determining switching band(s)or switching to band(s)for the switching period location.

Description
本申请要求在2023年04月14日提交中国国家知识产权局、申请号为202310431172.3,发明名称为“确定切换时间位置的方法及相关装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请涉及通信技术领域,尤其涉及一种确定切换时间位置的方法及相关装置。
在第五代移动通信技术(5th-Generation,5G)新空口(new radio,NR)中,进行下行传输时,接入网设备(例如,基站)的功率较大,可以实现很好的下行覆盖。然而,由于终端设备的发射功率有限,在进行上行传输时,上行覆盖可能受限。为了解决5G NR上行覆盖受限的问题,业界提出了辅助上行链路(supplementary uplink,SUL)技术,即在普通上行(normal uplink,NUL)载波(carrier)外配置额外的SUL载波以用于辅助上行传输,从而提高上行覆盖能力和容量。在SUL技术中,终端设备可以在NUL和SUL之间动态选择发送链路,该UL和SUL之间的切换即两频段(band)切换。在两band之间切换时,接入网设备可以通过配置索引(CC index)来指示切换时间(switching period)应该被放置在哪个band上。随着通信技术的发展,期望终端设备能够灵活地在三个甚至更多个band之间动态切换,以提升上行峰值速率,因此存在三个甚至更多个band之间切换的场景。针对这种三个甚至更多个band之间的切换,switching period位置到底在哪个band上,还未提出解决方案。
发明内容
本申请提供了一种确定切换时间位置的方法及相关装置,可在三个甚至更多个频域资源切换的场景下,实现对切换时间位置的确定,有利于提高通信的可靠性,以及最小化对频谱资源的浪费。
第一方面,本申请提供了一种确定切换时间位置的方法,由通信装置执行,该通信装置可以为终端设备或接入网设备,可选的,该通信装置也可以是终端设备或接入网设备中的模块。在该方法中,从至少一个第一频域资源切换至至少一个第二频域资源时,从至少一个第一频域资源和至少一个第二频域资源中,确定切换时间所在的频域资源。其中,该切换时间所在的频域资源为被调度进行信息传输的频域资源中,不具有最高优先级的频域资源,且切换时间所在的频域资源为至少一个第一频域资源或至少一个第二频域资源。可理解的,切换时间为从至少一个第一频域资源切换至至少一个第二频域资源的时间。
切换时间所在的频域资源为至少一个第一频域资源,即:切换时间所在的频域资源为切换前的频域资源。切换时间所在的频域资源为至少一个第二频域资源,即:切换时间所在的频域资源为切换后的频域资源。
可选的,上述“切换时间所在的频域资源为被调度进行信息传输的频域资源中,不具有最高优先级的频域资源,且切换时间所在的频域资源为至少一个第一频域资源或至少一个第二频域资源。”也可以替换为:切换时间所在的频域资源为信息传输会被切换时间影响的频域资源中,不具有最高优先级的频域资源,且切换时间所在的频域资源为切换前的频域资源或切换后的频域资源。这里,本申请中的“影响”也可以理解为干扰,中断或打断等,在此不做限制。
可选的,上述“切换时间所在的频域资源为被调度进行信息传输的频域资源中,不具有最高优先级的频域资源,且切换时间所在的频域资源为至少一个第一频域资源或至少一个第二频域资源。”也可以替换为:“切换时间所在的频域资源满足下述2个条件:条件1:切换时间所在的频域资源为至少一个第一频域资源或至少一个第二频域资源时,切换时间所在的频域资源中不包括具有最高优先级的频域资源;或者,切换时间所在的频域资源为切换前的频域资源时,切换前的频域资源不包括具有最高优先级的频域资源;和/或,切换时间所在的频域资源为切换后的频域资源时,切换后的频域资源不包括具有最高优先级的频域资源。条件2:切换时间所在的频域资源为至少一个第一频域资源或至少一个第二频域资源时,切换时间所在的频域资源的信息传输会被切换时间影响(即信息传输会被切换时间中断或部分中断);或者,切换时间所在的频域资源为切换前的频域资源时,切换前的频域资源中的信息传输会被切换时间影响;和/或,切换时间所在的频域资源为切换后的频域资源时,切换后的频域资源中的信息传输会被切换时间影响。”其中,上述信息传输包括数据信息传输,控制信息传输或者控制信号传输中至少一项。示例性地,信息传输可以为上行信息传输。
可选的,上述“切换时间所在的频域资源为被调度进行信息传输的频域资源中,不具有最高优先级的频域资源,且切换时间所在的频域资源为至少一个第一频域资源或至少一个第二频域资源。”也可以替换为:“确定切换时间所在的频域资源或切换时间所在的频域资源满足下述条件:第一条件:确定出的切换时间所在的频域资源所属的切换前的频率资源或切换后的频率资源不包含具有最高优先级的频域资源;第二条件:确定切换时间所在的频域资源为从信息传输会被切换时间所影响/中断的所述至少一个第一频域资源和所述至少一个第二频域资源中进行确定。”其中,上述“...所属”也理解为“...所在”或者“...所对应”。上述“…不包含”也替换为“...不为”,或者“..不包括”,或者“...不是”,或者“...不属于”等描述,在此不做限制。
在本申请中,针对三个甚至更多个频域资源之间的切换场景,切换时间所在的频域资源为被调度进行信息传输的频域资源中,不具有最高优先级的频域资源,这样有利于最小化对频谱资源浪费,同时还可以提高通信的可靠性。这里,之所以可以最小化对频域资源的浪费,是因为本申请中带宽大的频域资源的优先级大于带宽小的频域资源的优先级,选择切换时间的位置在优先级较低的频域资源上,可以保护优先级高的频域资源上的信息传输,因此,减少了对频域资源的浪费。
在一种可能的实现中,被调度进行信息传输的频域资源不是关联频域资源或不是第三频域资源。其中,第三频域资源上未被调度进行信息传输的时间的时长大于或者等于切换时间的时长。
可选的,被调度进行信息传输的频域资源不是关联频域资源或不是第三频域资源,也可以理解为:被调度进行信息传输的频域资源不包含关联频域资源或不包含第三频域资源,或者,也可以理解为:被调度进行信息传输的频域资源不为关联频域资源或不为第三频域资源,或者,也可以理解为:被调度进行信息传输的频域资源为非关联频域资源。
在该种实现方式下,在进行switching period location判断时,参与优先级比较的频域资源应该排除关联频域资源和/或第三频域资源,即依据在切换中所涉及的除了关联频域资源和/或第三频域资源以外的频域资源中具有最高优先级频域资源,来确定switching period location应该在切换前的频域资源还是切换后的频域资源,有利于最小化对频谱资源浪费,同时还可以提高通信的可靠性。
在一种可能的实现中,当具有最高优先级,且被调度进行信息传输的频域资源属于至少一个第一频域资源时,切换时间所在的频域资源为至少一个第二频域资源。可选的,当具有最高优先级,且被调度进行信息传输的频域资源属于至少一个第二频域资源时,切换时间所在的频域资源为至少一个第一频域资源。
在一种可能的实现中,被调度进行信息传输的频域资源上未被调度进行信息传输的时间的时长小于切换时间的时长。
可选的,上述被调度进行信息传输的频域资源上未被调度进行信息传输的时间的时长小于切换时间的时长也可以理解为:一个时间单元上,被调度进行信息传输的频域资源上未被调度进行信息传输的时间的时长小于切换时间的时长。具体来说,第一时间单元上,被调度进行信息传输的频域资源上未被调度进行信息传输的时间的时长小于切换时间的时长。第二时间单元上,被调度进行信息传输的频域资源上未被调度进行信息传输的时间的时长小于切换时间的时长。
在一种可能的实现中,至少一个第一频域资源对应于第一时间单元,至少一个第二频域资源对应于第二时间单元。其中,被调度进行信息传输的频域资源上,第一时间单元的结束位置与第一时间单元上被调度进行信息传输的结束位置的时间差为第一时长,第一时长小于切换时间的时长;或者,被调度进行信息传输的频域资源上,第二时间单元上被调度进行信息传输的起始位置与第二时间单元的起始位置的时间差为第二时长,第二时长小于切换时间的时长。
可选的,上述第一时间单元早于第二时间单元,且第一时间单元与第二时间单元相邻。

向接入网设备发送能力信息。其中,该能力信息用于指示终端设备支持同时并发的频域资源,和/或,用于指示终端设备不支持同时并发的频域资源。

本申请中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
应理解,说明书通篇中提到的“实施例”意味着与实施例有关的特定特征、结构或特性包括在本申请的至少一个实施例中。因此,在整个说明书各个实施例未必一定指相同的实施例。此外,这些特定的特征、结构或特性可以任意适合的方式结合在一个或多个实施例中。
本申请实施例的技术方案可以应用于各种通信系统,例如:长期演进(long term evolution,LTE)系统、无线保真(wireless-fidelity,WiFi)系统、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)通信系统、第五代(5th generation,5G)系统或新无线(new radio,NR)以及未来的通信系统等,在此不做限制。
请参见图1,图1是一种通信系统的网络架构的示意图。如图1所示,通信系统10包括无线接入网(radio access network,RAN)100和核心网(core network,CN)200。可选的,该通信系统10还可以包括互联网300。RAN 100包括至少一个RAN节点(如图1中的110a和110b,统称为110)和至少一个终端设备(如图1中的120a-120j,统称为120)。RAN 100中还可以包括其它RAN节点,例如,无线中继设备和/或无线回传设备(图1中未示出)等。终端设备120通过无线的方式与RAN节点110相连。RAN节点110通过无线或有线方式与核心网200连接。核心网200中的核心网设备与RAN 100中的RAN节点110可以分别是不同的物理设备,也可以是集成了核心网逻辑功能和无线接入网逻辑功能的同一个物理设备。
RAN 100可以为第三代合作伙伴计划(3rd generation partnership project,3GPP)相关的蜂窝系统,例如,4G、5G移动通信系统、或面向未来的演进系统(例如6G移动通信系统)。RAN 100还可以是开放式接入网(open RAN,O-RAN或ORAN)、云无线接入网络(cloud radio access network,CRAN)、或者无线保真(wireless fidelity,WiFi)系统。RAN 100还可以是以上两种或两种以上系统融合的通信系统。
RAN节点110,有时也可以称为接入网设备,无线接入网设备,RAN实体或接入节点等,构成通信系统的一部分,用以帮助终端设备实现无线接入。通信系统10中的多个RAN节点110可以为同一类型的节点,也可以为不同类型的节点。在一些场景下,RAN节点110和终端设备120的角色是相对的,例如,图1中网元120i可以是直升机或无人机,其可以被配置成移动基站,对于那些通过网元120i接入到RAN 100的终端设备120j来说,网元120i是基站;但对于基站110a来说,网元120i是终端设备。RAN节点110和终端设备120有时都称为通信装置,例如图1中网元110a和110b可以理解为具有基站功能的通信装置,网元120a-120j可以理解为具有终端设备功能的通信装置。
在一种可能的场景中,RAN节点可以是基站(base station)、演进型基站(evolved NodeB,eNodeB)、接入点(access point,AP)、发送接收点(transmission reception point,TRP)、下一代基站(next generation NodeB,gNB)、第六代(6th generation,6G)移动通信系统中的下一代基站、未来移动通信系统中的基站、或WiFi系统中的接入节点等。RAN节点可以是宏基站(如图1中的110a)、微基站或室内站(如图1中的110b)、中继节点或施主节点、或者是CRAN场景下的无线控制器。可选的,RAN节点还可以是服务器,可穿戴设备,车辆或车载设备等。例如,车辆外联(vehicle to everything,V2X)技术中的接入网设备可以为路侧单元(road side unit,RSU)。本申请中的RAN节点的全部或部分功能也可以通过在硬件上运行的软件功能来实现,或者通过平台(例如云平台)上实例化的虚拟化功能来实现。本申请中的RAN节点还可以是能实现全部或部分RAN节点功能的逻辑节点、逻辑模块或软件。
在另一种可能的场景中,由多个RAN节点协作协助终端设备实现无线接入,不同RAN节点分别实现基站的部分功能。例如,RAN节点可以是集中式单元(central unit,CU),分布式单元(distributed unit,DU),CU-控制面(control plane,CP),CU-用户面(user plane,UP),或者无线单元(radio unit,RU)等。CU和DU可以是单独设置,或者也可以包括在同一个网元中,例如基带单元(baseband unit,BBU)中。RU可以包括在射频设备或者射频单元中,例如包括在射频拉远单元(remote radio unit,RRU)、有源天线处理单元(active antenna unit,AAU)或远程射频头(remote radio head,RRH)中。
在不同系统中,CU(或CU-CP和CU-UP)、DU或RU也可以有不同的名称,但是本领域的技术人员可以理解其含义。例如,在ORAN系统中,CU也可以称为O-CU(开放式CU),DU也可以称为O-DU,CU-CP也可以称为O-CU-CP,CU-UP也可以称为O-CU-UP,RU也可以称为O-RU。为描述方便,本申请中以CU,CU-CP,CU-UP、DU和RU为例进行描述。本申请中的CU(或CU-CP、CU-UP)、DU和RU中的任一单元,可以是通过软件模块、硬件模块、或者软件模块与硬件模块结合来实现。
终端设备也可以称为终端,终端设备可以广泛应用于各种场景,例如,设备到设备(device-to-device,D2D)、车物(vehicle to everything,V2X)通信、机器类通信(machine-type communication,MTC)、物联网(internet of things,IOT)、虚拟现实、增强现实、工业控制、自动驾驶、远程医疗、智能电网、智能家具、智能办公、智能穿戴、智能交通、智慧城市等。终端设备包括向用户提供语音和/或数据连通性的设备,
例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的处理设备。该终端设备可以经无线接入网与核心网进行通信,该终端设备可以包括用户设备(user equipment,UE)、无线终端设备、移动终端设备、设备到设备通信(device-to-device,D2D)终端设备、车到一切(vehicle to everything,V2X)终端设备、机器到机器/机器类通信(machine-to-machine/machine-type communications,M2M/MTC)终端设备、物联网(internet of things,IoT)终端设备、订户单元、订户站,移动站、远程站、接入点(access point,AP)、远程终端、接入终端、用户终端、用户代理、或用户装备等。例如,可以包括移动电话(或称为“蜂窝”电话),具有移动终端设备的计算机,便携式、袖珍式、手持式、计算机内置的移动装置等。例如,个人通信业务(personal communication service,PCS)电话、无绳电话、会话发起协议(session initiation protocol,SIP)话机、无线本地环路(wireless local loop,WLL)站、个人数字助理(personal digital assistant,PDA)、等设备;还可以包括受限设备,例如功耗较低的设备,或存储能力有限的设备,或计算能力有限的设备等。此外,该终端设备也可以为车载终端,例如,集成在车辆中的车载盒子(telematics box,T-Box)、域控制器(domain controller,DC)、多域控制器(multi domain controller,MDC)或车载单元(onboard unit,OBU)。可选的,该终端设备还可以是手机、平板电脑、带无线收发功能的电脑、可穿戴设备、车辆、无人机、直升机、飞机、轮船、机器人、机械臂、智能家居设备等。本申请的实施例对终端的设备形态不做限定。
需要说明的是,本申请中的终端设备可以支持三个甚至更多个band(或载波)。以下本申请主要以三个或四个band之间的切换作为示例进行说明。
应当理解的是,本申请实施例中的终端设备可以是上述任意一种设备或芯片,具体此处不做限定。无论作为设备还是作为芯片,该终端设备都可以作为独立的产品进行制造、销售或者使用。在本实施例以及后续实施例中,仅以终端设备为例进行介绍。
应当理解的是,本申请实施例中用于实现接入网设备的功能的装置可以是接入网设备本身,也可以是能够支持接入网设备实现该功能的装置,例如芯片系统或可实现接入网设备功能的组合器件、部件,该装置可以被安装在接入网设备中。本申请实施例中,芯片系统可以由芯片构成,也可以包括芯片和其他分立器件。在本实施例以及后续实施例中,仅以接入网设备为例进行介绍。
需要说明的是,在5G NR中,进行下行传输时,接入网设备的功率较大,可以实现很好的下行覆盖。然而,由于终端设备的发射功率有限,在进行上行传输时,上行覆盖可能受限。为了解决5G NR上行覆盖受限的问题,业界提出了SUL技术,即在UL载波外配置额外的SUL载波以用于辅助上行传输,由于SUL采用的是频点较低的频段,例如1.8G频段,信号损耗较小,因此可以提高上行覆盖能力和容量。终端设备可以在NUL和SUL之间动态选择发送链路,但是在同一个时刻,终端设备只能选择其中的一条发送,不能同时在两条上行链路上进行发送,这个称之为SUL与NUL之间的切换,NUL和SUL之间的切换为两频段(band)切换。
示例性地,请参见图2,图2是本申请实施例提供的共站址和异站址的上行射频链切换的场景示意图。如图2中(a)为共站址的上行射频链切换场景,(b)为异站址的上行射频链切换场景。其中,终端设备可以支持两个上行载波(uplink carrier,UL carrier)(例如,载波001和载波002,其中,载波001可以是NUL载波,载波002可以是SUL载波),并且,终端设备在该两个上行载波能够进行上行射频链切换。
随着通信技术的发展,终端设备可能支持三个甚至更多个band,并且,能够在该至少三个band上进行上行射频链切换。一个band可以包含至少一个载波。其中,该终端设备支持的至少三个上行载波可以是SUL场景中的载波。例如,至少三个上行载波中有一个NUL载波(例如,主上行载波(primary uplink carrier,primary UL carrier)或辅上行载波(secondary uplink carrier,secondary UL carrier))和至少一个SUL载波;或者,至少三个上行载波中有至少一个NUL载波(例如,主上行载波或辅上行载波)和一个SUL载波。可选的,该终端设备支持的至少三个上行载波也可以是载波聚合(carrier aggregation,CA)场景中的载波。例如,一个主载波(primary component carrier,PCC)和至少一个辅载波(secondary component carrier,SCC),在此不做限制。
需要说明的是,在至少三个上行载波上支持上行射频链切换,可以理解为,该至少三个上行载波中的每两个上行载波之间的射频链均可以实现切换。例如,终端设备支持在载波A、载波B和载波C上进行上行射频链切换,则该终端设备可以在载波A和载波B之间进行上行射频链切换,并且,可以在载波A和载波C之间进行上行射频链切换,并且,可以在载波B和载波C之间进行上行射频链切换。
下面对本申请实施例涉及的相关技术特征进行解释说明。需要说明的是,这些解释是为了让本申请实施例更容易被理解,而不应该视为对本申请所要求的保护范围的限定。
1、上行射频链切换(Uplink Tx Switch)
上行射频链切换指终端设备将射频链从某一个band(或载波)切换至另一个band(或载波),以支持在该另一个band(或载波)上进行上行传输。在进行上行射频链切换的这段时间称为上行射频链切换期间,也被称为切换时间(switching period),还可以称为switching time,或switching gap等,在此不做限制。切换时间用于射频链的调整(tuning)或重调整(retuning)。切换时间的位置(switching period location)即switching period位于哪个band或载波。
需要说明的是,一个band(载波)上可以有1个射频链传输(即1Tx或1T),或者,一个band(或载波)上也可以同时有两个射频链传输(即2Tx或2T)。示例性地,在band A上有1个射频链传输可以表示为A1T,在band A上有两个射频链传输可以表示为A 2T。
对于一个终端设备而言,其最多可以同时支持两个射频链,该1个或者两个射频链可以通过1个端口(port)传输,即1Tx可以对应发生在1端口(port)上,或者,2Tx也可以对应发生在1个port上,具体根据实际配置确定,在此不做限制。
可选的,切换时间的起始位置与结束位置之间的时长,可以描述为切换时间的时长。示例的,切换时间的时长可以是终端设备通过能力信息上报的,或者,通过协议预定义的,或者,可以是预配置的,或者,也可以是接入网设备指示给终端设备的,或者,也可以是接入网设备基于终端设备的能力信息指示给终端设备的,对此不做限定。一般来说,不同的频段对可以对应不同的切换时间的时长。
示例性地,以切换时间占据4个符号为例,对应的切换时间的时长为140us,频域资源的子载波间隔为30KHz。可选的,切换时间的时长还可以是35us,210us,或280us中任意值。可选的,切换时间的时长不限定为上述列举的值,其还可以是其他值,在此不做限制。
2、CA
CA是将至少两个成员载波(component carrier,CC)(也被称为载波单元)聚合在一起以支持更大的传输带宽。其中,PCC对应的小区为主小区(primary cell,Pcell),该主小区是终端设备进行初始连接建立的小区;或者,进行无线资源控制(radio resource control,RRC)连接重建的小区;或者,在切换(handover)过程中指定的小区。Pcell负责与UE之间的RRC通信。SCC对应的小区为辅小区(secondary cell,Scell),该辅小区是在RRC连接重配置时添加/修改/释放的,用于提供额外的无线资源。
3、发射通道(transmitter,TX)
TX是一个物理概念,也可以称为射频(radiofrequency,RF)发射通道或射频链(radio frequency chain,RF Chain)或发送链(transmission chain)等。在本申请中,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:发射通道可以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。本申请中均简称为射频链。可选的,本申请中射频链也可以替换为Tx、T、天线、射频、发射通道、发送端口、射频链数量、传输层数、传输的最大层数、传输支持的最大层数、接收通道或者它们的任意组合。可选的,本申请中的射频链切换,可以替换为上行射频链切换,也可以替换为动态上行射频链切换。
4、频段(band)
band原本指电磁波的频率范围,在通信领域指能够用于通信的电磁波频段。一般地,一个band包括一个或多个载波(carrier)。本申请中,终端设备向接入网设备上报一个或多个band,接入网设备会从前述一个或多个band中选一个或多个载波配置给该终端设备,该终端设备采用前述接入网设备配置的载波进行通信。
5、频段对(band pair)
band pair指两个能够进行射频链切换的频段组合。一般地,一个频段对中包含两个band,代表该两个band可以进行上行射频链切换。例如,频段对为{A,B},表示频段对包含band A和band B这两个频段,并且,band A和band B能够进行上行射频链切换。也就是说,band A上的上行射频链可以切换到band B上,并且,band B上的上行射频链可以切换到band A上。
6、关联band(associated band)
关联band是用于解决传输模糊性的。当两个射频链目前分别位于band A和B,且下一个传输是band C上的1port传输时,如果RRC信令uplinkTxSwitching-DualUL-TxState指示的是1T,那么将会有一个射频链被切换到band C。这种情况下,由于不清楚到底切换的是band A还是band B的射频链,3gpp标准定义了关联band。即,对于任何一个band,通过RRC信令配置其关联band,当调度该一个band上的1port传输时,如果RRC信令uplinkTxSwitching-DualUL-TxState指示的是1T,那么除了该band上的1port传输,还有1T在其关联band上。
对于三个band,四个band或更多band切换中的每个band(即传输band),都有其对应的关联band。除了一个射频链在传输band上,另一个射频链总是在对应的关联band上。也就是说,当切换涉及2T切换为1T时,需要引出关联band用于确定频域资源对。
举例来说,以band A,band B,band C和band D为例,每个传输band的关联band可以被配置为band A的关联band是band B,band B的关联band是band A,band C的关联band是band A,band D的关联band是band C。例如,当band C的1port传输被调度时,如果在之前的slot上射频链为band A和band B上各1T,鉴于band A是band C的关联band,那么band B上的射频链被切换到band C上,而band A上的维持不变,从而使得在当前的slot上射频链为band C和band A上各1T。又例如,当band D的1port传输被调度时,如果在之前的slot上射频链为band A和B1T上各1T,鉴于band C是band D的关联band,那么band A上的射频链被切换到band D上,而band B上的被切换到band C上,或者,band B上的射频链被切换到band D上,而band A上的被切换到band C上,从而使得在当前的slot上射频链为band C和band D上各1T。上述定义关联band的前提都是假设两个band上的同时传输能被终端设备支持。
可理解,以下本申请中的band A可以简称为A,band B可以简称B,band C可以简称为C,band D可以简称为D。
需要说明的是,在两band之间切换时,接入网设备可以通过配置索引(CC index)来指示切换时间(switching period)应该被放置在哪个band上,即指示切换时间的位置(switching period location)。随着通信技术的发展,终端设备可能支持三个甚至更多个上行载波,因此可能存在三个甚至更多个band之间的切换,当涉及三个甚至更多个band之间切换时,通过配置CC index来指示switching period location的方式不再适用,因此需要提出新的方案来确定switching period位置到底在哪个band上,以提高通信的可靠性。
在一些实现方式中,当三个甚至更多个band之间的切换时,针对switching period location具体应该在哪个band或哪个载波上,提出了一种准则,为方便区分,以下称为准则1。对该准则1描述如下:对于一次切换涉及的所有bands,UE确定switching period location为不是最高优先级band所在的switching-from band(s)或switching-to band(s)。即,The UE determines the switching period location on either switching-from band(s)or switching-to band(s)that is involved in the UL Tx switching and is not with the highest priority band.
上述通过从一次切换涉及的所有bands中确定出最高优先级band,并将最高优先级band不在的switching-from band(s)或switching-to band(s)作为switching period location方式虽然简单,但是在一些特定切换场景下会导致频谱效率降低。
例如,对于如图3所示的切换场景:A+C→B,本申请中,“→”表示切换,A和C为切换前的band,B为切换后的band。如果所调度的band B是1port传输,且uplinkTxSwitching-DualUL-TxState被配置为1T,那么需要考虑band B的关联band D来进行切换,即涉及的频段对为band pair 1:A→B,band pair 2:C→D。如果优先级配置为band D的优先级高于band A的优先级,band A的优先级高于band C的优先级,band C的优先级高于band B的优先级(简述为D>A>C>B),那么参照准则1的定义,由于band D优先级最高,因此选择switch from band(即band A和C)作为switching period location。这种情况下,由于中断了具有较高优先级的band A和band C上的信息传输,而保护了最低优先级的band B上的信息传输,也保护了根本不传数据的band D,这是因为band D只是关联band,其上并没有调度信息传输,因此频谱效率较低。
又例如,对于如图4所示的切换场景:A 2T→B,如果所调度的band B是1port传输,且uplinkTxSwitching-DualUL-TxState被配置为1T,那么同样需要考虑band B的关联band D来进行切换,即涉及的频段对为band pair 1:A→B,band pair 2:A→D。如果优先级配置为D>A>B,那么参照准则1的定义,由于band D优先级最高,因此选择switch from band(即band A)作为switching period location。这种情况下,同样中断了具有较高优先级的A上的信息传输,而保护了最低优先级的B上的信息传输,也保护了根本不传数据的band D,因此使得频谱效率较低。
本申请中,频域资源的优先级可以用于确定切换时间的位置,具体确定方式可参见后续各个实施例中的描述,在此不进行赘述。可选的,频域资源的优先级也可以理解为以下任一种描述:信息在频域资源上的传输优先级,或者保护频域资源上传输的优先级,或者不在频域资源的设置切换时间的优先级,或者不为切换时间的位置所在的频域资源的优先级。
再例如,对于如图5所示的切换场景:band pair 1:A→B,band pair 2:C→D。如果优先级配置为A>B>D>C(或者A>D>B>C),那么参照准则1的定义,由于band A优先级最高,因此选择switch to bands(即band B和D)作为switching period location。这种情况下,也是中断了具有较高优先级的band D的信息传输,而保护了最低优先级的band C上的信息传输,因此频谱效率较低。
基于此,本申请提出了一种确定切换时间位置的方法,该方法对于三个甚至更多个band之间的切换,可以确定出切换时间所在的位置,最小化对频谱资源浪费,有利于提高通信的可靠性。
需要说明的是,本申请实施例中的“根据……”和“基于……”的描述可以相互替换。应理解,“包含”是集合与集合之间的关系,“属于”是元素与集合之间的关系。其中“X包含于Y”可以替换描述为:“Y包括X”,或者,“Y包含X”,例如X={1,2},Y={1,2,3},这种集合X中的每一个元素都能在集合Y中找到,就称集合X包含于集合Y,或者,集合Y包括X,或者,Y包含X。又例如X={1,2},那么元素1就属于集合X。可选的,在本申请实施例中,X包括于Y,X包含于Y,Y包括X,Y包含X,或者X属于Y,X位于Y这几种描述之间也可以相互替换。
本申请实施例中,信息传输包括控制信道信息传输,数据信道信息传输,或参考信号信息传输。其中,参考信号包含探测参考信号(sounding reference signal,SRS),解调参考信号(demodulation reference signal,DMRS),或信道状态信息参考信号(channel state information reference signal,CSI-RS)等中至少一项。“被调度进行信息传输”可以理解为:有信息传输,或存在信息传输。相应地,“未被调度进行信息传输”也可以理解为:没有信息传输,或不存在信息传输,或空符号。“没有信息传输”即正交频分符号被空置,或正交频分符号上没有信息传输。被调度进行信息传输包含:被配置(configured)进行信息传输或被授权(granted)进行信息传输。其中,被配置可以为无线资源控制(radio resource control,RRC)信令配置。被授权可以为下行控制信息(downlink control information,DCI)授权。本申请中的“传输”可以是“发送”,也可以是“接收”。
应理解,本申请中被调度进行信息传输,未被调度进行信息传输,或存在未被调度进行信息传输是针对一个时间单元而言的。例如,针对一个slot。
本申请中,“被调度进行信息传输的频域资源”是一个固定搭配,其中,并非任何存在信息传输的频域资源都可以被称为“被调度进行信息传输的频域资源”,“被调度进行信息传输的频域资源”需要满足以下条件①:被调度进行信息传输的频域资源上未被调度进行信息传输的时间的时长小于切换时间的时长,或者,一个时间单元(例如时隙)上未被调度进行信息传输的时间(例如符号)的长度小于切换时间的时长的频域资源为被调度进行信息传输的频域资源,或者,一个时间单元上被调度进行信息传输的时间的长度大于第三时长,其中第三时长=一个时间单元的长度-切换时间的时长。
举例来说,如图6所示,假设band A的一个slot上未被调度进行信息传输的时间(即空符号)的长度为3个符号(如图6中的符号11~符号13),被调度进行信息传输的时间(即有信息传输的符号)的长度为11个符号(如图6中的符号0~符号10),其中切换时间的时长的4个符号,由于未被调度进行信息传输的时间的长度(即3个符号)小于切换时间的时长(即4个符号),其满足条件①,因此,band A为被调度进行信息传输的频域资源。
再举例来说,如图7所示,假设band B的一个slot上未被调度进行信息传输的时间(即空符号)的长度为4个符号(如图7中的符号10~符号13),被调度进行信息传输的时间(即有信息传输的符号)的长度为10个符号(如图7中的符号0~符号9),其中切换时间的时长的4个符号,由于未被调度进行信息传输的时间的长度(即4个符号)等于切换时间的时长(即4个符号),其不满足条件①,因此,band A不为被调度进行信息传输的频域资源。
本申请中,时间单元可以理解为子帧(subframe),或时隙(slot),或迷你子帧(mini-subframe),或迷你时隙(mini-slot),或子时隙(sub-slot),或符号(symbol/OFDM symbol)等。作为示例,本申请主要以一个时间单元为一个时隙为例进行说明。
本申请中,“存在未被调度进行信息传输的时域资源的频域资源”是一个固定搭配,可选的,“存在未被调度进行信息传输的时域资源的频域资源”也可以描述为“存在未被调度进行信息传输的时域资源对应/所在的频域资源”。其中,“存在未被调度进行信息传输的时域资源的频域资源”需要满足以下条件②:存
在未被调度进行信息传输的时域资源的频域资源是关联频域资源或第三频域资源。其中第三频域资源上未被调度进行信息传输的时间的时长大于或者等于切换时间的时长,也就是说,第三频域资源满足如下条件③:一个时间单元(例如时隙)上未被调度进行信息传输的时间(例如符号)的长度大于或者等于切换时间的时长的频域资源为第三频域资源。可理解的,由于关联频域资源上无有效发送,或描述为关联频域资源的一个时隙上皆为空符号,或描述为关联频域资源上没有任何信息传输,因此,关联频域资源其实是一种特殊的第三频域资源,即关联频域资源也满足作为第三频域资源的条件③。
举例来说,如图8所示,假设band A的一个slot上未被调度进行信息传输的时间的时长为5个符号(如图8中符号9~符号13),被调度进行信息传输的时间的时长为9个符号(如图8中符号0~符号8),其中切换时间的时长的4个符号,由于未被调度进行信息传输的时间的时长(即5个符号)大于切换时间的时长(即4个符号),其满足条件③,因此,band A为第三频域资源,同时band A也为“存在未被调度进行信息传输的时域资源的频域资源。
又举例来说,如图9所示,假设band B上无有效发送,或描述为band B一个slot上皆为空符号,或描述为band B上没有任何信息传输,因此,band B为关联band,同时band B也为“存在未被调度进行信息传输的时域资源的频域资源”。
需要说明的是,本申请实施例中至少一个第一频域资源对应于第一时间单元,至少一个第二频域资源对应于第二时间单元。第一时间单元早于第二时间单元,且第一时间单元与第二时间单元相邻(即第一时间单元和第二时间单元为相邻时间单元)。例如,如图10所示,假设至少一个第一频域资源为band A和band C,至少一个第二频域资源为band B和band D。其中,band A和band C对应于第一时间单元,band B和band D对应与第二时间单元。
可选的,上述“被调度进行信息传输的频域资源”还可以理解为:被调度进行信息传输的频域资源上,第一时间单元的结束位置与第一时间单元上被调度进行信息传输的结束位置的时间差为第一时长,该第一时长小于切换时间的时长。也就是说,在第一时间单元的第一时长的时域资源上,未被调度进行信息传输。
举例来说,如图11所示,假设第一时间单元为slot1,第二时间单元为slot2,每个slot包括14个符号(即符号0~符号13),切换时间的时长为4个符号。其中band A的slot1的结束位置为符号13,若slot1上被调度进行信息传输的结束位置为符号10,由于13-10=3<4,因此band A为被调度进行信息传输的频域资源。也可以理解为:切换时间在band A上时,切换时间所在的band A的信息传输会被切换时间影响。其中,一个符号上的信息传输会被切换时间中断。
可选的,上述“被调度进行信息传输的频域资源”还可以理解为:被调度进行信息传输的频域资源上,第二时间单元上被调度进行信息传输的起始位置与第二时间单元的起始位置的时间差为第二时长,该第二时长小于切换时间的时长。也就是说,在第二时间单元的第二时长的时域资源上,未被调度进行信息传输。
举例来说,如图12所示,假设第一时间单元为slot1,第二时间单元为slot2,每个slot包括14个符号(即符号0~符号13),切换时间的时长为4个符号。其中band A的slot2的起始位置为符号0,若slot2上被调度进行信息传输的起始位置为符号3,由于3-0=3<4,因此band A为被调度进行信息传输的频域资源。也可以理解为:切换时间在band A上时,切换时间所在的band A的信息传输会被切换时间影响。其中,三个符号上的信息传输会被切换时间中断。
可选的,上述“存在未被调度进行信息传输的时域资源的频域资源”还可以理解为:被调度进行信息传输的频域资源上,第一时间单元的结束位置与第一时间单元上被调度进行信息传输的结束位置的时间差为第一时长,该第一时长大于或等于切换时间的时长。也就是说,在第一时间单元的第一时长的时域资源上,未被调度进行信息传输。
举例来说,如图13所示,假设第一时间单元为slot1,第二时间单元为slot2,每个slot包括14个符号(即符号0~符号13),切换时间的时长为4个符号。其中band A的slot1的结束位置为符号13,若slot1上被调度进行信息传输的结束位置为符号9,由于13-9=4,因此band A为未被调度进行信息传输的频域资源。也可以理解为:切换时间在band A上时,切换时间所在的band A的信息传输不会被切换时间影响。其中,4个空置符号的时长可以满足切换时间。
可选的,上述“存在未被调度进行信息传输的时域资源的频域资源”还可以理解为:被调度进行信息传输的频域资源上,第二时间单元上被调度进行信息传输的起始位置与第二时间单元的起始位置的时间差为第二时长,该第二时长大于或等于切换时间的时长。也就是说,在第二时间单元的第二时长的时域资源上,未被调度进行信息传输。
举例来说,如图14所示,假设第一时间单元为slot1,第二时间单元为slot2,每个slot包括14个符号(即符号0~符号13),切换时间的时长为4个符号。其中band A的slot2的起始位置为符号0,若slot2上被调度进行信息传输的起始位置为符号5,由于5-0=5>4,因此band A为未被调度进行信息传输的频域资源。也可以理解为:切换时间在band A上时,切换时间所在的band A的信息传输不会被切换时间影响。其中,5个空置符号的时长可以满足切换时间。
本申请实施例中,“在切换时间,从…切换至…”也可以理解为:“切换时间用于从…切换至…”。本申请实施例中,“在切换时间”也可以理解为,“在切换时间内”,或“在切换时间上”,或“经过/通过切换时间”。
本申请实施例中的“组”或“组合”的描述可以理解为:“对”。例如,“频域资源组”和“频域资源对”的描述可以相互替换。需要说明的是,本申请实施例中涉及的频域资源可以理解为频段(band)或载波(carrier)。作为一个示例,频域资源理解为频段时,子频域资源可以为载波。例如以下图15,图19以及图21所示实施例中的频域资源可以理解为频段或载波,图18和图23所示实施例中的频域资源应理解为频段,子频域资源理解为载波。
此外,本申请实施例中,switch from即切换前/切换自,例如切换前的频域资源即切换自频域资源或从该频域资源切换。switch to即切换后/切换至,例如切换后的频域资源即切换至频域资源或切换到该频域资源。对应的,switch from band/CC即切换前band/CC或者切换自band/CC,switch to band/CC即切换后band/CC或者切换至band/CC。一个频域资源组或一个频域资源对包含一个switch from band/CC和一个switch to band/CC。
本申请实施例中具有第一射频链发送能力可以理解为:具有不同频域资源对的射频链独立发送的能力,或者,具有高级能力(即UE indicates true in the capability[tx-on-non-affected-band]),或者,具有高级的射频链发送能力。射频链独立发送的含义为一条射频链的发送不受另一条射频链切换的影响。即,该另一条射频链在切换期间时,该一条射频链仍能发送。例如,在一条射频链1在切换期间,另外一条射频链2也能进行发送。
本申请实施例中的具有第二射频链发送能力可以理解为:具有不同频域资源对的射频链非独立发送的能力,或者,不具有高级能力(即UE does not indicates True in the capability[tx-on-non-affected-band]),或者,不具有高级的射频链发送能力。射频链非独立发送的含义为一条射频链的发送受另一条射频链切换的影响。即,该另一条射频链在切换期间时,该一条射频链不能发送,也会中断信息传输。也就是说,两个射频链不能独立工作,需要受对方影响。例如,一条射频链1在切换期间,另外一条射频链2不能进行发送,也即需要等射频链1切换完,射频链2才能进行发送。
本申请中,不具有最高优先级的频域资源,也可以理解为:具有最低优先级的频域资源。即,当确定切换时间所在的频域资源时,排除最高优先级的频域资源所在的切换前频域资源或切换后频域资源,也可以理解为:当确定切换时间所在的频域资源时,设置最低优先级的频域资源所在的切换后频域资源或切换前频域资源,作为切换时间所在的频域资源。本申请中,最高优先级,可以理解为较高优先级。最低优先级,可以理解为较低优先级。
需要说明的是,本申请中需要确定切换时间所在的频域资源的前提条件是,网络设备调度的第一时间单元上的信息传输与第二时间单元上的信息传输之间的不需要进行上行传输或者不进行上行传输的时域范围或时间差(gap)小于终端设备需要的切换时间。不需要进行上行传输或者不进行上行传输的时间差可以理解为空置符号。这些不需要进行上行传输或者不进行上行传输的时间差为连续空置符号。
下面对本申请提供的确定切换时间位置及相关装置进行详细介绍:
需要说明的是,本申请实施例针对三个甚至更多个band之间的切换,关于switching period location的确定方式,提出了一种新的准则,以下称为准则2,对该准则2的描述如下:
UE确定switching period location为:除了关联band以外,不是最高优先级的band所在的switching-from band(s)或switching-to band(s)。也可以理解为,当从涉及在切换中的频域资源中确定具有最高优先级的频域资源时,将关联band不作为涉及在切换中的频域资源,或者不把关联band考虑在内进行确定。然后,基于该确定出的具有最高优先级的频域资源,进一步确定切换时间所在的频域资源为非该具有最高优先级的频域资源所在的切换前频域资源或切换后频域资源。应理解,非关联频域资源,即除了关联频域资源以外的频域资源。
和/或,UE确定switching period location为:除了信息传输不会被切换时间影响的band以外,不是最高
优先级的band所在的switching-from band(s)或switching-to band(s)。也可以理解为,当从涉及在切换中的频域资源中确定具有最高优先级的频域资源时,将“信息传输不会被切换时间影响的频域资源”不作为涉及在切换中的频域资源,或者不把“信息传输不会被切换时间影响的频域资源”考虑在内进行确定。然后,基于该确定出的具有最高优先级的频域资源,进一步确定切换时间所在的频域资源为非该具有最高优先级的频域资源所在的切换前频域资源或切换后频域资源。
其中,涉及在切换中的频域资源为至少一个第一频域资源与至少一个第二频域资源的集合。
即,The UE determines the switching period location on either switching-from band(s)or switching-to band(s)that is involved in the UL Tx switching and is not with the highest priority band except the associated band/the band wherein the switching period will not interrupt the UL transmission in this band.
可选的,切换时间不会中断该band上的上行传输也可以描述为切换时间不会影响该band上的上行传输。
可选的,对该准则2的描述也可以为:当涉及关联band时,如果关联band具有最高优先级,则在确定switching period location时,应将其排除,即将该关联band从涉及在上行切换的频段之中排除。
和/或,当涉及关联band时,则在确定switching period location时,应将其排除,即将该关联band从涉及在上行切换的频段之中排除。
和/或,当涉及“信息传输不会被切换时间影响的频域资源”时,如果该频域资源具有最高优先级,则在确定switching period location时,应将其从涉及在上行切换的频段之中排除。
和/或,当涉及“信息传输不会被切换时间影响的频域资源”时,则在确定switching period location时,应将其从涉及在上行切换的频段之中排除。
其中,涉及在切换中的频域资源为至少一个第一频域资源与至少一个第二频域资源的集合。
即,When associated bands/the band wherein the switching period will not interrupt the UL transmission in this band involved,(if the associated band/the band wherein the switching period will not interrupt the UL transmission in this band is of the highest priority),it should be excluded from the band(s)that is involved in the UL Tx switching,when determining the switching period location.
可选的,对该准则2的描述也可以为:当关联band的优先级最高时,应从涉及在切换中的频域资源频段列表中排除,以确定switching period location为switching-from band(s)或switching-to band(s)。和/或,当“信息传输不会被切换时间影响的频域资源”的优先级最高时,应从涉及在切换中的频域资源列表中排除,以确定switching period location为switching-from band(s)或switching-to band(s)。
即,When the associated band/the band wherein the switching period will not interrupt the UL transmission in this band is of highest priority,it should be excluded from the band list for determining switching band(s)or switching to band(s)for the switching period location.
针对准则2,请参见图15,图15是本申请实施例提供的确定切换时间位置的一流程示意图。如图15所示,该确定切换时间位置包括如下步骤S1501。图15所示的方法执行主体可以为终端设备或接入网设备。或者,图15所示的方法执行主体可以为终端设备或接入网设备中的芯片。其中:
S1501、从至少一个第一频域资源切换至至少一个第二频域资源时,从至少一个第一频域资源和至少一个第二频域资源中,确定切换时间所在的频域资源。其中,切换时间所在的频域资源为被调度进行信息传输的频域资源中,不具有最高优先级的频域资源,且切换时间所在的频域资源为至少一个第一频域资源或至少一个第二频域资源。
应理解,切换时间为从至少一个第一频域资源切换至至少一个第二频域资源的时间。需要说明的是,本申请实施例中不同频域资源对的切换时间的时长可以不同。本申请中,该至少一个第一频域资源和至少一个第二频域资源中包括至少两个频域资源对,任意一个频域资源对中包括两个频域资源。可选的,频域资源对也可以描述为频段对(band pair)。可选的,至少两个频域资源对中包括至少三个频域资源,也就是说,第一频域资源的数量和第二频域资源的数量之和大于或者等于3。
应理解,本申请实施例中至少一个第一频域资源为切换前的频域资源(switching-from band(s)),至少一个第二频域资源为切换后的频域资源(switching-to band(s)),再换句话说,本申请将切换前的频域资源描述为至少一个第一频域资源,将切换后的频域资源描述为至少一个第二频域资源,如有需要,不同描述方式之间可以相互替换。可理解的,至少一个第一频域资源和至少一个第二频域资源为本次切换涉及的所有频域资源,由至少一个第一频域资源和至少一个第二频域资源组成的频域资源集合以下描述为第二频域
资源集合。由至少一个第一频域资源和至少一个第二频域资源中被调度进行信息传输的频域资源组成的频域资源集合以下描述为第一频域资源集合。也就是说,第一频域资源集合为第二频域资源集合的子集,或者理解为第一频域资源集合中包括的频域资源为从第二频域资源集合中排除关联频域资源和/或第三频域资源之后,被保留下来的频域资源。可选的,本申请中的至少一个第一频域资源和至少一个第二频域资源为终端设备支持进行切换的频域资源。
可选的,上述从至少一个第一频域资源切换至至少一个第二频域资源时,从至少一个第一频域资源和至少一个第二频域资源中,确定切换时间所在的频域资源,也可以替换描述为以下5种描述方式中的任一种:
①从至少一个第一频域资源切换至至少一个第二频域资源时,基于至少一个第一频域资源和至少一个第二频域资源中具有最高优先级,且被调度进行信息传输的频域资源,确定切换时间所在的频域资源。
②从至少一个第一频域资源切换至至少一个第二频域资源时,基于至少一个第一频域资源和至少一个第二频域资源中被调度进行信息传输的频域资源中具有最高优先级的频域资源,确定切换时间所在的频域资源。
③从至少一个第一频域资源切换至至少一个第二频域资源时,基于至少一个第一频域资源和至少一个第二频域资源中信息传输会被切换时间中断的频域资源,确定具有最高优先级的频域资源。
④从至少一个第一频域资源切换至至少一个第二频域资源时,基于至少一个第一频域资源和至少一个第二频域资源中具有最高优先级且信息传输会被切换时间中断的频域资源,确定切换时间所在的频域资源。
⑤从至少一个第一频域资源切换至至少一个第二频域资源时,确定第一频域资源集合,并根据第一频域资源集合中具有最高优先级的频域资源,从至少一个第一频域资源和至少一个第二频域资源中确定切换时间所在的频域资源。其中,第一频域资源集合中包括的频域资源为被调度进行信息传输的频域资源。且第一频域资源集合中包括的频域资源为涉及在切换中的频谱资源。其中,第一频域资源集合可以理解为是根据第二频域资源集合确定的,即确定第二频域资源集合,基于第二频域资源集合确定第一频域资源集合。其中,第二频域资源集合中包括的频域资源为该至少一个第一频域资源和至少一个第二频域资源,第一频域资源集合为第二频域资源集合的子集。可理解的,属于第二频域资源集合且不属于第一资源集合的频域资源为存在未被调度进行信息传输的时域资源的频域资源,有关“存在未被调度进行信息传输的时域资源的频域资源”的理解参见前述解释,在此不再赘述。
可选的,切换时间所在的频域资源为被调度进行信息传输的频域资源中,不具有最高优先级的频域资源,且切换时间所在的频域资源为至少一个第一频域资源或至少一个第二频域资源。也可以替换为:“切换时间所在的频域资源”满足下述2个条件:
条件1:切换时间所在的频域资源为至少一个第一频域资源或至少一个第二频域资源时,切换时间所在的频域资源中不包括具有最高优先级的频域资源。
条件2:切换时间所在的频域资源为至少一个第一频域资源或至少一个第二频域资源时,切换时间所在的频域资源的信息传输会被切换时间影响(即信息传输会被切换时间中断或部分中断)。
本申请中,切换时间所在的频域资源为至少一个第一频域资源可以替换为:切换时间所在的频域资源为切换前的频域资源;切换时间所在的频域资源为至少一个第二频域资源可以替换为:切换时间所在的频域资源为切换后的频域资源。
切换时间所在的频域资源为至少一个第一频域资源,即切换时间所在的频域资源属于或位于至少一个第一频域资源;切换时间所在的频域资源为至少一个第二频域资源,即切换时间所在的频域资源属于或位于至少一个第二频域资源。
切换时间所在的频域资源中不包括,也可以理解为至少一个第一频域资源中/至少一个第二频域资源中的频域资源不为,或者至少一个第一频域资源中/至少一个第二频域资源中的任一频域资源不为。可选的,当具有最高优先级,且被调度进行信息传输的频域资源属于至少一个第一频域资源时,切换时间所在的频域资源为至少一个第二频域资源。也就是说,当具有最高优先级,且被调度进行信息传输的频域资源位于切换前时,切换时间所在的频域资源为切换后的频域资源。可选的,当具有最高优先级,且被调度进行信息传输的频域资源属于至少一个第二频域资源时,切换时间所在的频域资源为至少一个第一频域资源。也就是说,当具有最高优先级,且被调度进行信息传输的频域资源位于切换后时,切换时间所在的频域资源为切换前的频域资源。
可选的,上述被调度进行信息传输的频域资源可以理解为:被调度进行信息传输的频域资源上未被调度进行信息传输的时间的时长小于切换时间的时长。应理解,本申请中的被调度进行信息传输,是针对一个时间单元而言的。有关“被调度进行信息传输的频域资源”的理解参见前述解释,在此不再赘述。
可选的,上述被调度进行信息传输的频域资源还可以理解为:被调度进行信息传输的频域资源不是关联频域资源和/或不是第三频域资源。其中,第三频域资源上未被调度进行信息传输的时间的时长大于或者等于切换时间的时长。也就是说,当至少一个第一频域资源和至少一个第二频域资源中包括关联频域资源,关联频域资源被排除之后的剩余频域资源为被调度进行信息传输的频域资源。当至少一个第一频域资源和至少一个第二频域资源中包括第三频域资源时,第三频域资源被排除之后的剩余频域资源为被调度进行信息传输的频域资源。当至少一个第一频域资源和至少一个第二频域资源中既包括关联频域资源,又包括第三频域资源时,关联频域资源和第三频域资源皆被排除之后的剩余频域资源为被调度进行信息传输的频域资源。
为方便理解图15所示实施例,以下结合具体的示例进行说明。
示例1,如图16所示的切换场景:A+C→B,如果所调度的band B是1port传输,且uplinkTxSwitching-DualUL-TxState被配置为1T,那么需要考虑band B的关联band D来进行切换,即涉及的频段对为band pair 1:A→B,band pair 2:C→D。如果优先级配置为D>A>C>B,那么参照准则2的定义,虽然band D的优先级最高,但由于band D为关联band,因此,需要排除band D,从剩余band(即band A,C和B)中确定具有最高优先级的band,其中,band A具有最高优先级,因此选择switch to band(即band B和D)作为switching period location。
示例2,如图17所示的切换场景:A 2T→B,如果所调度的band B是1port传输,且uplinkTxSwitching-DualUL-TxState被配置为1T,那么同样需要考虑band B的关联band D来进行切换,即涉及的频段对为band pair 1:A→B,band pair 2:A→D。如果优先级配置为D>A>B,那么参照准则2的定义,虽然band D的优先级最高,但是band D为关联band,因此,需要排除band D,剩余band(即band A和B)中确定具有最高优先级的band,其中,band A具有最高优先级,因此选择switch to band(即band B和D)作为switching period location。
可选的,图15所示的实施例中,同一优先级的频域资源的数量可以为一个,或者,同一优先级的频域资源的数量也可以为多个。例如,被调度进行信息传输的频域资源中具有最高优先级频域资源的数量可以为1个。又例如,当被调度进行信息传输的频域资源中具有最高优先级频域资源的数量为多个时,该多个具有最高优先级频域资源要么全部位于切换前,要么全部位于切换后。
在本申请实施例中,针对三个甚至更多个频域资源之间的切换场景,在进行switching period location判断时,参与优先级比较的频域资源应该排除关联频域资源和/或第三频域资源。即依据在切换中所涉及的除了关联频域资源和/或第三频域资源以外的频域资源中具有最高优先级频域资源,来确定switching period location应该在切换前的频域资源还是切换后的频域资源,有利于最小化对频谱资源浪费,同时还可以提高通信的可靠性。
本申请还提供图18所示的实施例。可选的,图18所示的实施例可以与图15所示实施例结合,例如,在图15实施例的基础上进一步包括如下步骤:
S1801、终端设备向接入网设备发送能力信息。相应地,接入网设备接收来自终端设备的能力信息。
其中,能力信息用于指示终端设备支持同时并发的频域资源,例如能力信息指示band A和band B,即band A和band B支持同时并发。或者,能力信息也可以指示的是终端设备不支持同时并发的频域资源,例如能力信息指示band A和band B,即band A和band B不支持同时并发。或者,能力信息用于指示终端设备支持的关联频域资源,例如能力信息指示band A的关联频域资源为band B。或者,能力信息用于指示终端设备支持的频域资源和终端设备支持的频域资源的关联频域资源,例如能力信息指示band A和band A的关联频域资源band B。
可选的,能力信息还用于指示期望同时并发的频域资源中的一个频域资源的优先级高于另一个作为关联频域资源的频域资源的优先级,例如,能力信息指示band A和band A的关联频域资源band B,且band A的优先级高于band B。
本申请中,某频域资源的优先级可以理解为该频域资源不被配置switching period location的优先级。相应的,优先级最高的某频域资源可以理解为switchingperiod location不倾向于被配置在该频域资源上的。优先级最低的某频域资源也可以理解为switchingperiod location倾向于被配置在该频域资源上的。
可选的,某频域资源的优先级也可以理解为该频域资源被配置switching period location的优先级。相应的,优先级最高的某频域资源可以理解为switchingperiod location倾向于被配置在该频域资源上的。优先级最低的某频域资源也可以理解为switchingperiod location不倾向于被配置在该频域资源上的。对于这种方案,本申请中实施例中的优先级最高,可以相应替换为优先级最低。
可选的,能力信息还用于指示终端设备支持的射频链发送能力,这里射频链发送能力包括第一射频链发送能力或第二射频链发送能力。
可选的,能力信息还可以用于指示在确定切换时间位置时,以switch to所在的最高优先级band作为判断依据,即切换时间所在的频域资源为switch from。可选的,能力信息还可以用于指示在确定切换时间位置时,以switch from所在的最高优先级band作为判断依据,即切换时间所在的频域资源为switch to。
可选的,能力信息还可以用于指示在确定切换时间位置时,依据子频域资源的优先级(sub-priority level)作为判断依据。
需要说明的是,S1801为可选步骤。
S1802、接入网设备向终端设备发送第一配置信息。相应地,终端设备接收来自接入网设备的第一配置信息。
其中,第一配置信息用于配置至少一个第一频域资源和至少一个第二频域资源的优先级信息,该至少一个第一频域资源和至少一个第二频域资源中的频域资源的优先级不同。或者,第一配置信息用于配置频域资源的优先级信息。可选的,优先级信息可以为数值,或者索引。可选的,优先级信息还可以为一个列表。在该列表中,前后顺序代表了优先级高低。例如,优先级信息为True的频段:A,B,C。优先级信息为False的频段:D。那么优先级最低的为A,依次B,依次C,即:频域资源的优先级为A<B<C。优先级最高的为D。基于该优先级信息(或按照该优先级顺序),这些频段不被配置switching period location。又例如,优先级信息为True的频段:A,B,C。优先级信息为False的频段:D。那么优先级最低的为C,依次B,依次A。优先级最高的为D。基于该优先级信息(或按照该优先级顺序),这些频段不被配置switching period location。又例如,优先级信息为False的频段:A,B,C。优先级信息为True的频段:D。那么优先级最高的为A,依次B,依次C。优先级最低的为D。基于该优先级信息(或按照该优先级顺序),这些频段不被配置switching period location。又例如,优先级信息为False的频段:A,B,C。优先级信息为True的频段:D。那么优先级最高的为C,依次B,依次A。优先级最低的为D。基于该优先级信息(或按照该优先级顺序),这些频段不被配置switching period location。
可选的,接入网设备还可以根据接收到的能力信息向终端设备发送第一配置信息。
S1803、接入网设备向终端设备发送第二配置信息。相应地,终端设备接收来自接入网设备的第二配置信息。
其中,第二配置信息用于配置频域资源的关联频域资源。或者,第二配置信息用于配置至少一个第一频域资源和至少一个第二频域资源中任意一个频域资源的关联频域资源。其中,配置的第四频域资源的优先级高于第四频域资源的关联频域资源的优先级,第四频域资源为至少一个第一频域资源和至少一个第二频域资源中的一个频域资源。
可选的,接入网设备还可以根据接收到的能力信息向终端设备发送第二配置信息。

可选的,上述S1802和S1803执行顺序不受限制。
在本申请实施例中,在接入网设备进行优先级配置时便配置关联频域资源的优先级不会高于被其关联的频域资源,从而可以有效避免后续根据最高优先级频域资源所确定的switching period location是参考关联频域资源所做的决定,这样可最小化对频谱资源浪费,有利于提高通信的可靠性。
请参见图19,图19是本申请实施例提供的确定切换时间位置的另一流程示意图。如图19所示,该确定切换时间位置包括如下步骤S1901~S1902。图19所示的方法执行主体可以为终端设备或接入网设备。
或者,图19所示的方法执行主体可以为终端设备或接入网设备中的芯片。其中:
S1901、从至少一个第一频域资源切换至至少一个第二频域资源时,若终端设备具有第一射频链发送能力,则根据一个频域资源对中频域资源的优先级,确定第一切换时间所在的频域资源。
在一种实现中,从至少一个第一频域资源切换至至少一个第二频域资源时,需要根据终端设备的射频
链发送能力,确定切换时间所在的频域资源。示例性地,若终端设备具有第一射频链发送能力,则根据一个频域资源对中频域资源的优先级,确定第一切换时间所在的频域资源。也就是说,当终端设备具有第一射频链发送能力时,切换时间所在频域资源的确定只参照本次切换所涉及的一个频域资源对中所包含的两个频域资源的优先级进行选择,不参照此次切换所涉及的所有频域资源进行选择。再换句话说,对于具有第一射频链发送能力的终端设备而言,让各频域资源对各自切各自的,而不是根据所有频域资源对中最高优先级一方来确定。为方便描述,后续将该种切换时间位置确定方式称为准则3.1。
基于准则3.1,第一切换时间所在的频域资源为一个频域资源对中,不具有最高优先级的频域资源,或者描述为,第一切换时间所在的频域资源不为一个频域资源对中,具有最高优先级的频域资源。一个频域资源对中包括两个频域资源,至少一个第一频域资源切换和至少一个第二频域资源包括至少两个频域资源对。
可选的,第一切换时间为一个频域资源对中频域资源切换的时间。示例性地,不同频域资源对中频域资源切换的时间的时长可以不同。
举例来说,如图20所示的切换场景:band pair 1:A→B,band pair 2:C→D。如果优先级配置为A>B>D>C(或者A>D>B>C),那么根据上述定义的准则3.1,在band pair 1中,由于band A的优先级最高,因此UE选择band B作为switching period location。在band pair 2中,由于band D的优先级最高,因此UE选择band C作为switching period location。其中,band pair1中切换时间为切换时间1,band pair 2中切换时间为切换时间2,切换时间1的时长小于切换时间2的时长。
可选的,上述准则3.1还需要在满足某个条件时才适用。该条件可以为具有最高优先级的频域资源不位于切换后(即最高优先级的频域资源位于切换前)。也就是说,在另一种实现中,上述若终端设备具有第一射频链发送能力,则根据一个频域资源对中频域资源的优先级,确定第一切换时间所在的频域资源,也可以理解为:当具有最高优先级的频域资源不位于切换后(即最高优先级的频域资源位于切换前),且终端设备具有第一射频链发送能力时,根据一个频域资源对中频域资源的优先级,确定第一切换时间所在的频域资源。为方便描述,后续将该种切换时间位置确定方式称为准则3.2,也就是说,准则3.2进一步规定了准则3.1的适用条件,只有满足该适用条件时,准则3.1才适用。再换句话说,当不满足该适用条件时,准则3.1不适用,而适用准则2。这里,适用条件可以为具有最高优先级的频域资源不位于切换后(即最高优先级的频域资源位于切换前)。
需要说明的是,基于准则3.2来确定切换时间位置,可简化实现复杂度,这里,之所以可以简化实现复杂度是因为如果需要结合终端设备的射频发射能力来决定切换时间的位置,参与切换时间位置判定的条件更多。通常来说,选择在一个slot的末尾一个或多个符号上进行射频链的调整或重调整,相对于选择在一个slot的起始一个或多个符号上进行射频链的调整或重调整更容易,终端设备更容易实现。因此,假设有slot1和slot2,且slot1位于slot2之前,当最高优先级的频域资源位于切换后,而终端设备需要选择在slot1的末尾一个或多个符号上进行射频链的调整或重调整时,可以采用准则3.2来确定切换时间位置。而当最高优先级的频域资源位于切换前,而终端设备需要选择在slot2的起始一个或多个符号上进行射频链的调整或重调整时,可以采用准则3.1来确定切换时间位置,即结合终端设备的射频链能力进行判定,以减少终端设备复杂度。
举例来说,请一并参见图20所示的切换场景,由于最高优先级的频域资源为band A,且band A位于切换前,因此适用准则3.2,根据准则3.2,在band pair 1中,由于band A的优先级最高,因此UE选择band B作为switching period location。在band pair 2中,由于band D的优先级最高,因此UE选择band C作为switching period location。
可理解的,有关第一射频链发送能力的理解参见前述相关描述,在此不再赘述。
S1902、从至少一个第一频域资源切换至少一个第二频域资源时,若终端设备具有第二射频链发送能力,则从至少一个第一频域资源和至少一个第二频域资源中,确定第二切换时间所在的频域资源。
其中,第二切换时间所在的频域资源为被调度进行信息传输的频域资源中,不具有最高优先级的频域资源,且第二切换时间所在的频域资源为至少一个第一频域资源或至少一个第二频域资源。也就是说,当终端设备具有第二射频链发送能力时,切换时间所在的频域资源的确定适用准则2。再换句话,当终端设备具有第二射频链发送能力时,切换时间所在频域资源的确定需要参照该切换所涉及的所有频域资源对中所有被调度进行信息传输的band中具有最高优先级的band进行选择,而不能参照每个频域资源对涉及的两个band进行选择。为方便描述,后续将这里S1902描述的切换时间位置确定方式称为准则3.3。准则
3.3与准则2的区别在于,准则3.3进一步规定了准则2的适用条件,该适用条件为终端设备具有第二射频链发送能力。
举例来说,请一并参见图5所示的切换场景,假设终端设备具有第二射频链发送能力,那么根据准则3.3,由于band A优先级最高,因此选择switch to bands(即band B和D)作为switching period location。
又举例来说,请一并参见图16所示的切换场景,假设终端设备具有第二射频链发送能力,那么根据准则3.3,虽然band D的优先级最高,但由于band D为关联band,因此,需要排除band D,从剩余band(即band A,C和B)中确定具有最高优先级的band,其中,band A具有最高优先级,因此选择switch to band(即band B和D)作为switching period location。
再举例来说,请一并参见图17所示的切换场景,假设终端设备具有第二射频链发送能力,那么根据准则3.3,虽然band D的优先级最高,但是band D为关联band,因此,需要排除band D,剩余band(即band A和B)中确定具有最高优先级的band,其中,band A具有最高优先级,因此选择switch to band(即band B和D)作为switching period location。
其中,第二切换时间为从至少一个第一频域资源切换至至少一个第二频域资源的时间。可选的,至少一个第一频域资源切换至至少一个第二频域资源包括的至少两个频域资源对中,不同频域资源对的第二切换时间的时长可以不同。
可理解的,有关第二射频链发送能力的理解参见前述相关描述,在此不再赘述。
在本申请实施例中,结合终端设备的射频发送能力来确定切换时间的位置,实现方式灵活,有利于减小对信息传输的影响,除此之外,还提高了通信的可靠性。
请参见图21,图21是本申请实施例提供的确定切换时间位置的另一流程示意图。如图21所示,该确定切换时间位置包括如下步骤S2101。图21所示的方法执行主体可以为终端设备或接入网设备。或者,图21所示的方法执行主体可以为终端设备或接入网设备中的芯片。其中:
S2101、从至少一个第一频域资源切换至至少一个第二频域资源时,从至少一个第一频域资源和至少一个第二频域资源中,确定切换时间所在的频域资源。其中,切换时间所在的频域资源基于至少一个第一频域资源和至少一个第二频域资源中的目标频域资源确定,目标频域资源为至少一个第一频域资源和至少一个第二频域资源中的多个最高优先级的频域资源中的一个,多个最高优先级的频域资源中的一部分最高优先级的频域资源包含于至少一个第一频域资源,多个最高优先级的频域资源中的另一部分最高优先级的频域资源包含于至少一个第二频域资源。
在一些可行的实施方式中,当至少一个第一频域资源和至少一个第二频域资源中包括多个最高优先级的频域资源时,该多个最高优先级的频域资源中的一部分最高优先级的频域资源位于切换前,另一部分最高优先级的频域资源位于切换后。例如,假设至少一个第一频域资源和至少一个第二频域资源中具有两个最高优先级的频域资源,那么该两个最高优先级的频域资源中的一个最高优先级的频域资源属于至少一个第一频域资源,两个最高优先级的频域资源中的另一个最高优先级的频域资源属于至少一个第二频域资源。其中,上述至少一个第一频域资源为切换前的频域资源,至少一个第二频域资源为切换后的频域资源。可选的,该多个最高优先级的频域资源为被调度进行信息传输的频域资源,或者,该多个最高优先级的频域资源不为关联频域资源或第三频域资源。
可选的,上述目标频域资源为至少一个第一频域资源和至少一个第二频域资源中的多个最高优先级的频域资源中的一个可以理解为:目标频域资源属于切换前的频域资源,或者,目标频域资源属于切换后的频域资源。可选的,也描述为:目标频域资源位于切换前,或者,目标频域资源位于切换后。
可理解的,上述切换时间所在的频域资源为目标频域资源不在的那一方。例如,假设目标频域资源位于切换前,那么切换时间所在的频域资源为切换后的频域资源(即切换时间所在的频域资源为至少一个第二频域资源)。又假设目标频域资源位于切换后,那么切换时间所在的频域资源为切换前的频域资源(即切换时间所在的频域资源为至少一个第一频域资源)。为方便描述,后续将这种切换时间的位置确定方式称为准则4.1。需要说明的是,上述准则4.1可以是终端设备作为能力上报的,或者是协议规定的,或者是接入网设备配置的,或者,也可以是预配置的等,在此不做限制。
为方便理解,后续本申请主要以多个最高优先级的频域资源的数量为两个为例进行说明,即至少一个第一频域资源和至少一个第二频域资源中具有两个最高优先级的频域资源,其中一个最高优先级的频域资源位于切换前,另一个最高优先级的频域资源位于切换后。基于此,上述准则4.1可以定义为:当存在两个最高优先级band,且分别位于两个频域资源对的切换前的频域资源和切换后的频域资源时,可以规定以
switch to所在的最高优先级band作为判断依据,即优选切换时间所在的频域资源为switch from,这样终端设备用于切换时间的为一个slot的末尾一个或者多个符号,有利于终端设备进行处理,减少对传输在一个slot的前面多个符号上的参考信号的中断。可选的,也可以规定以switch from所在的最高优先级band作为判断依据,即切换时间所在的频域资源为switch to,这样终端设备用于切换时间的为一个slot的起始一个或者多个符号,在进行不是从一个slot的起始符号开始就被调度进行上行信息传输的场景,有利于终端设备减少符号上的传输中断。
举例来说,如图22所示的切换场景:band pair 1:A→B,band pair 2:C→D,其中优先级配置为A=D>B>C,那么参照上述定义,如图22中(a),若优先以switch to所在的最高优先级band作为判断依据(即优选切switch from),因此选择switch from band(即band A和C)作为switching period location。可选的,如图22中(b),若优先以switch from所在的最高优先级band作为判断依据(即优选切switch to),因此选择switch from band(即band B和D)作为switching period location。
在另一些可行的实施方式中,也可以规定同一优先级的频域资源只有一个,当至少一个第一频域资源和至少一个第二频域资源中具有一个最高优先级的频域资源时,切换时间所在的频域资源为被调度进行信息传输的频域资源中,不具有最高优先级的频域资源,且切换时间所在的频域资源为至少一个第一频域资源或至少一个第二频域资源。也就是说,当规定同一优先级的频域资源的数量只有一个时,切换时间位置的确定方式可参见准则2。
在本申请实施例中,通过定义准则4.1,解决了多个频域资源同为最高优先级时,switching period location的判断冲突。
请参见图23,图23是本申请实施例提供的确定切换时间位置的另一流程示意图。如图23所示,该确定切换时间位置包括如下步骤S2301。图23所示的方法执行主体可以为终端设备或接入网设备。或者,图23所示的方法执行主体可以为终端设备或接入网设备中的芯片。其中:
S2301、从至少一个第一频域资源切换至至少一个第二频域资源时,根据至少一个第一频域资源切换和至少一个第二频域资源中具有最高优先级的频域资源和具有最高优先级的频域资源中包括的多个子频域资源的优先级,确定切换时间所在的频域资源。
其中,切换时间所在的频域资源为至少一个第一频域资源或至少一个第二频域资源,具有最高优先级的频域资源属于至少一个第一频域资源,且属于至少一个第二频域资源。切换时间所在的频域资源为至少一个第一频域资源或至少一个第二频域资源。切换时间为从至少一个第一频域资源切换至至少一个第二频域资源的时间。可选的,该具有最高优先级的频域资源为被调度进行信息传输的频域资源。需要说明的是,切换前的具有最高优先级的频域资源中的子频域资源与切换后的具有最高优先级的频域资源中的子频域资源不同。
示例性地,具有最高优先级的频域资源中包括的多个子频域资源的优先级关系可以为:多个子频域资源中带宽大的子频域资源的优先级高于带宽小的子频域资源的优先级。可选的,当多个子频域资源的带宽相等时,频点较高的子频域资源的优先级高于频点较低的子频域资源的优先级,或者,频点较低的子频域资源的优先级高于频点较高的子频域资源的优先级。应理解,若频点较高的子频域资源的优先级高于频点较低的子频域资源的优先级,则可以最大化频谱资源使用率,这是因为频点较高的频段带宽较大。应理解,若频点较低的子频域资源的优先级高于频点较高的子频域资源的优先级,则可以减少对于覆盖性能较好的频段的中断,这是因为频点较低的频段衰减较小。其中,上述频点即中心频点。
举个例子,假设具有最高优先级的频域资源中包括的多个子频域资源分别为CC1和CC2,其中若CC1的带宽大于CC2的带宽,则CC1的优先级高于CC2的优先级。在一种实现中,若CC1的带宽等于CC2的带宽,且CC1的中心频点高于CC2的中心频点,则CC1的优先级高于CC2的优先级。可选的,在另一种实现中,若CC1的带宽等于CC2的带宽,且CC1的中心频点高于CC2的中心频点,则CC2的优先级高于CC1的优先级。为方便理解,后续主要以频点较高的子频域资源的优先级高于频点较低的子频域资源的优先级为例进行示意性说明。
可理解的,上述根据至少一个第一频域资源切换和至少一个第二频域资源中具有最高优先级的频域资源和具有最高优先级的频域资源中包括的多个子频域资源的优先级,确定切换时间所在的频域资源可以理解为:
切换时间所在的频域资源为第五频域资源不在的那一方,即第五频域资源不在的切换前频域资源或切换后频域资源。其中第五频域资源为被调度进行信息传输的频域资源中具有最高优先级的频域资源,且第五频域资源中的子频域资源为该多个子频域资源中具有最高优先级的子频域资源。也就是说,可以规定当基于频域资源的优先级无法确定出切换时间所在的频域资源时,可以进一步以优先级高的子频域资源所在的最高优先级频域资源作为判断依据,即选择优先级低的子频域资源所在的最高优先级频域资源所属的一方作为切换时间所在的频域资源。为方便描述,后续将这种切换时间的位置确定方式称为准则5.1。
在一种实现中,至少一个第一频域资源和至少一个第二频域资源中具有两个最高优先级的频域资源。基于此,上述具有最高优先级的频域资源属于至少一个第一频域资源,且属于至少一个第二频域资源,可以理解为:两个最高优先级的频域资源中的一个最高优先级的频域资源属于至少一个第一频域资源,两个最高优先级的频域资源中的另一个最高优先级的频域资源属于至少一个第二频域资源。也就是说,一个最高优先级的频域资源位于切换前,一个最高优先级的频域资源位于切换后。
举例来说,如图24所示的切换场景:band pair 1:A→B,band pair 2:C→D,其中优先级配置为A=D>B>C,那么参照准则5.1的定义,band A的优先级和band D的优先级最高,且band A和band D分别位于切换前和切换后,其中,band A中包括CC1,band D中包括CC2,CC1的带宽100M大于CC2的带宽60M,因此,CC1的优先级高于CC2的优先级。以优先级高的子频域资源所在的最高优先级band作为判断依据,因此选择switch from band(即band B和D)作为switching period location。
在另一种实现中,至少一个第一频域资源和至少一个第二频域资源中具有一个最高优先级的频域资源。具有最高优先级的频域资源属于至少一个第一频域资源,且属于至少一个第二频域资源,可以理解为:该一个最高优先级的频域资源属于至少一个第一频域资源,且属于至少一个第二频域资源。也就是说,该一个最高优先级的频域资源既位于切换前,同时也位于切换后。可选的,在又一种实现中,也可以规定同一优先级频域资源中只有一个CC。
举例来说,如图25所示的切换场景:band pair 1:A→B,band pair 2:C→A,其中优先级配置为A>B>C,那么参照准则5.1的定义,band A的优先级最高,band A既位于切换前,又位于切换后,其中,band A中包括CC1和CC2,CC1的带宽100M大于CC2的带宽60M,因此,CC1的优先级高于CC2的优先级。以优先级高的子频域资源所在的最高优先级band作为判断依据,因此选择switch from band(即band B和A)作为switching period location。
又举例来说,如图26所示的切换场景:band pair 1:A→B,band pair 2:C→A,其中优先级配置为A>B>C,那么参照准则5.1的定义,band A的优先级最高,band A既位于切换前,又位于切换后,其中,band A中包括CC1和CC2,CC1的带宽等于CC2的带宽,其中CC1的频点为2.1GHz,CC2的中心频点为2.6GHz,因此,CC2的优先级高于CC1的优先级。以优先级高的子频域资源所在的最高优先级band作为判断依据,因此选择switch from band(即band B和A)作为switching period location。
在本申请实施例中,通过定义准则5.1,解决了同一band下不同CC位于switch from/to,且只配了band优先级时,或者,多个频域资源同为最高优先级时,switching period location的判断冲突,也保证了各CC间切换时能参考CC优先级进行switching period location的判定。
在本申请的各个实施例,可以单独作为一个实施例,如果没有特殊说明以及逻辑冲突,不同的实施例之间的术语和/或描述具有一致性、且可以相互引用,不同的实施例中的技术特征根据其内在的逻辑关系可以组合形成新的实施例。
可选的,在本申请中,假设切换场景为从band A和band C切换至band B和band D,那么到底band B和band D中哪个与band A组成一个band pair,哪个与band C组成另一个band pair,可以遵循下述规则:选择最低优先级的band与最高优先级的band组成一个band pair进行切换。示例性地,如果切换时间所在的频域资源为切换后的频域资源,且band A在band A,B,C和D中具有最高优先级,那么就选择band B和band D中具有最低优先级的band与band A组成一个band pair进行切换。例如假设band B的优先级低于band D的优先级,那么就选择band B和band A组成一个band pair进行切换,选择band D和band C组成另一个band pair进行切换。再示例性地,如果切换时间所在的频域资源为切换前的频域资源,且band B在band A,B,C和D中具有最高优先级,那么就选择band A和band C中具有最低优先级的band与band B组成一个band pair进行切换,例如假设band A的优先级低于band C的优先级,那么就选择band B和band A组成一个band pair进行切换,选择band D和band C组成另一个band pair进行切换。
