Description

上行配置方法、上行选择方法及其装置、通信系统 技术领域
本发明涉及通信领域，特别涉及一种上行配置方法、上行选择方法及其装置、通信系统。
背景技术
在未来通信系统中，例如新无线(NR)系统中，为了补偿高频场景部署时的上行覆盖问题，提出了上行覆盖补充的部署方式，即可以配置补充上行(Supplementary Uplink,SUL)，作为常规上行(Normal UL,NUL)或非补充上行(Non-supplementary Uplink,NUL)的辅助。图1是通信系统的一示意图，如图1所示，当一个小区配置了SUL时，该小区将会对应有两个上行载波，一个为SUL，一个为NUL，以及一个下行载波。
对于初始接入到配置了SUL的小区，如果且仅如果测得的下行质量低于一个广播的阈值，终端设备才会选择SUL载波；一旦开始，随机接入过程的所有上行传输将保持在选择的载波上进行。另外，SUL不同于载波聚合的上行。首先，SUL和NUL属于相同小区，而载波聚合的不同上行属于不同小区；其次，终端被调度在SUL或SUL对应的NUL上进行传输，但不会在两个载波上同时传输。例如，当一个小区配置了SUL时，只对小区的两个上行载波中的一个使用配置的上行授权(configured uplink grant)。
应该注意，上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
近年来，基于进一步扩大容量的考虑，长期演进(LTE，Long Term Evolution)技术开始了利用非授权频段传输的研究。从Rel.14(版本14)开始，引入了增强型许可频谱辅助接入(eLAA)，并在eLAA中引入了非授权频段的上行传输机制，同时为了保证和其他在非授权频段工作的技术共存，采用了先听后说(Listen-Before-Talk) 的信道竞争接入机制。
对于基于NR在非授权频段上的接入机制(NR based access to unlicensed spectrum,NR-U)，有以下几种部署场景：
场景A：授权频段上NR与NR-U间的载波聚合(Carrier Aggregation,CA)
场景B：授权频段上LTE与NR-U间的双连接(Dual Connectivity,DC)
场景C：独立的NR-U
场景D：下行在非授权频段上、上行在授权频段上的NR小区
场景E：授权频段上NR与NR-U间的双连接
当使用非授权频段为终端设备提供服务时，由于网络设备和/或终端设备在进行通信前，需要进行监听，即通过LBT机制，确定信道是否空闲。当信道空闲时，网络设备和/或终端设备发送同步块、参考信号、下行控制信息、下行数据和用于信道检测的参考信号等。在网络设备和/或终端设备监听到信道忙碌的情况下，下行/上行传输不能进行，这样网络设备和/或终端设备可能无法完成原定的参考信号的传输。
发明人发现，网络设备和/或终端设备对非授权频段上的参考信号的测量结果不只受到信号传播路径质量的影响，还与LBT成功/失败率相关，即测量结果可能无法真实地反映所测信道的无线链路的好坏，这会对非授权频段上的无线通信产生影响，例如，使得原本应该选择NUL的终端设备错误地选择了SUL。通常，SUL的频率低于NUL，载波效率差。当服务小区中一定数量的终端设备错误地选择了SUL时，服务小区的吞吐量降低。
为了解决上述问题，本发明实施例提供一种上行配置、选择方法及其装置、通信系统。

下面结合附图对本发明实施例进行说明。
实施例1
在现有的授权频段，当服务小区发起随机接入过程，且在服务小区配置了SUL时，可以使用服务小区的下行作为下行路损参考，将下行路损参考的参考信号接收功率(RSRP)的值与阈值进行比较，并根据比较结果选择SUL或NUL；但在非授权频段上，服务小区上发起了随机接入过程时，使用非授权频段的下行载波作为下行路损参考，考虑到网络侧LBT失败的影响，终端设备对下行路损参考的RSRP的测量结果可能比实际的无线链路情况差，这使得原本应该使用NUL的终端错误地选择了SUL。
在本实施例中，提供一种上行选择方法，针对工作在非授权频段的终端设备，不为终端设备配置SUL，即不存在SUL的概念，终端设备不需要进行SUL和NUL之间的选择，从而能够避免终端设备错误的使用不合适的上行载波，提高服务小区的吞吐量。
图2A是本实施例1的上行选择方法流程图，应用于终端设备侧。如图2A所示，该方法包括：
步骤201，终端设备执行随机接入过程；
其中，该终端设备工作在非授权频段时的随机接入过程使用的参数，与该终端设备工作在授权频段时的随机接入过程中使用的参数相同。
在本实施例中，该随机接入过程包括在随机接入信道上发送随机接入前导码，并接收网络设备发送的随机接入响应RAR(终端设备计算RA-RNTI，并根据该RA-RNTI解扰下行控制信道PDCCH，成功解扰时，即能够进一步获取通过下行共享信道承载的RAR)。
在一个实施方式中，该参数相同表示：该终端设备工作在非授权频段时，媒体接入控制层实体使用授权频段上的第一上行载波执行随机接入过程。
在一个实施方式中，该参数为上行载波类型标识时，该参数相同表示：工作在非授权频段的终端设备在计算RA-RNTI时，不考虑上行载波类型标识，或者说，工作 在非授权频段的终端设备在计算随机接入无线网络临时标识RA-RNTI时，计算公式为RA-RNTI＝1+s_id+14×t_id+14×80×f_id，其中，t_id为时域索引，f_id和s_id为频域索引(例如t_id是一个系统帧中物理随机接入信道机会PRACH occasion的第一个时隙的索引，范围为[0,80)，f_id是PRACH occasion的频域索引，范围为[0,8)，s_id是PRACH occasion第一个OFDM符号的索引，范围为[0,14))。其中，工作在授权频段的终端设备在计算RA-RNTI时，计算公式不变，为RA-RNTI＝1+s_id+14×t_id+14×80×f_id+ul_carrier_id，由于没有配置SUL，只有一个UL，终端进行随机接入时使用NUL，即所述第一上行，那么该上行载波类型标识ul_carrier_id为0，相当于参数相同。
在一个实施方式中，该参数相同表示：工作在非授权频段的终端设备在计算RA-RNTI时，计算公式不变，为RA-RNTI＝1+s_id+14×t_id+14×80×f_id+ul_carrier_id，但对于公式中的上行载波类型标识ul_carrier_id，将该终端设备工作在授权频段时的随机接入过程中选择第一上行载波时的上行载波类型标识的值作为该上行载波类型标识ul_carrier_id的值；其中终端设备工作在授权频段时的随机接入过程中选择第一上行载波时的上行载波类型标识的值即终端设备工作在授权频段时，随机接入过程选择NUL时，ul_carrier_id为0，即工作在非授权频段的终端设备在计算RA-RNTI时的上行载波类型标识的值也为0。
图2B是本实施例1的上行选择方法流程图，应用于终端设备侧。如图2B所示，该方法包括：
步骤201'，终端设备接收网络设备发送的指示信息；该指示信息包含或不包含上行参数相关的指示域UL/SUL indicator；
其中，该终端设备工作在授权频段时，接收到的该指示信息为第一指示信息，该指示域为第一指示域，该第一指示信息包含该第一指示域，该终端设备工作在非授权频段时，接收到的该指示信息为第二指示信息，该指示域为第二指示域，该第二指示信息包含该第二指示域，或者不包含该第二指示域。
在本实施例中，该第二指示信息的格式与该第一指示信息的格式相同或不同，该第二指示信息不包含该第二指示域，或者，该第二指示信息包含该第二指示域，且该第二指示域保留，或该第二指示域与该第一指示域指示的内容不同。
在一个实施方式中，在该第一指示信息和该第二指示信息是用于调度物理下行共 享信道PDSCH的第一下行控制信息时，包括第一指示信息和该第二指示信息的格式相同，都为DCI format 1_0(由C-RNTI加扰)，或者该第二指示信息的格式与该第一指示信息的格式不同(例如第一下行控制信息的格式是DCI format 1_0，第二下行控制信息的格式是新设计的DCI format，或者第一指示信息和第二指示信息使用相同的DCI format，例如DCI format 1_0(相同或不同的RNTI加扰)，但包括的域不同)，该第二指示信息不包含该第二指示域，或者该第二指示信息包含该第二指示域，该第二指示域保留，或者该第二指示域用于非授权频段的随机接入相关的指示。在第一指示信息里包括的随机接入前导码索引的值不全是0，且该终端设备被配置了第二上行时，该第一指示域用于指示发送随机接入前导码的上行载波。
例如，对于工作在授权频段上的小区，在随机接入前导码索引的值不全是0，且该终端设备被配置了SUL时，该第一指示域UL/SUL indicator用于指示该小区哪个上行载波发送随机接入前导码，否则该第一指示域UL/SUL indicator保留。对于工作在非授权频段上的小区，该第二指示域UL/SUL indicator保留。
或者，例如，对于工作在授权频段上的小区，在随机接入前导码索引的值不全是0，且该终端设备被配置了SUL时，该第一指示域UL/SUL indicator用于指示该小区哪个上行载波发送PRACH的，否则该第一指示域UL/SUL indicator保留。对于工作在非授权频段上的小区，该第二指示域UL/SUL indicator用于非授权频段的随机接入相关的指示，例如该相关的指示包括：
1)随机接入签到的信道接入机制的指示；
2)随机接入过程类型的指示，例如2-step或者4step；
3)PRACH资源的时频域指示，例如频域有多个资源还是时域有多个资源；
4)随机接入响应RAR接收相关指示，例如，是否使用扩展的RAR接收窗(在信道负荷比较高的情况下，网络设备可以指示终端设备使用扩展的接收窗，否则使用与授权频段相同的RAR接收窗)。
在一个实施方式中，在该第一指示信息和该第二指示信息是用于指示激活或去激活小区SRS的指示信息，包括第一指示信息和该第二指示信息(媒体接入控制层控制单元MAC CE)的格式相同，或者该第二指示信息的格式与该第一指示信息的格式不同(例如MAC CE的格式不同)，该第二指示信息包含该第二指示域，即SUL域，该第二指示域保留，或者该第二指示信息不包含该第二指示域，该第一指示域用于指 示MAC CE适用于的载波配置的载波类型。该第一指示域的值为第一值时指示MAC CE适用于非授权频段上的小区的上行载波配置。
例如，对于工作在授权频段上的小区，该第一指示域指示该MAC CE适用于NUL载波还是SUL载波配置，对于工作在非授权频段上的小区，该第二指示域保留。即针对现有的SRS激活/去激活MAC CE的SUL域，将该域SUL替换为R，表示保留。
或者，例如，不区分第一指示信息和第二指示信息，该指示信息中的指示域置为1时，指示其适用于SUL载波配置，指示域置为0(第一值)时，指示其适用于NUL载波配置或非授权频段上的小区。
例如，对于非授权频段上的小区，使用不同于授权频段上的小区的指示信息SRS激活/去激活MAC CE，即该第二指示信息的格式与该第一指示信息的格式不同，该第二指示信息中不包括第二域，即SUL域或，第二域原UL域作为保留比特。
在一个实施方式中，在该第一指示信息和该第二指示信息是用于调度PUSCH的第二下行控制信息时，包括第一指示信息和该第二指示信息的格式相同，都为DCI format 0_0(由小区RNTI(C-RNTI)/配置调度的RNTI(CS-RNTI)/调制编码机制小区RNTI(MCS-C-RNTI)进行CRC加扰)，或者该第二指示信息的格式与该第一指示信息的格式不同(例如第一下行控制信息的格式是DCI format 0_0，第二下行控制信息的格式是新设计的DCI format，或者第一指示信息和第二指示信息使用相同的DCI format，例如DCI format 0_0(相同或不同的RNTI加扰)，但包括的域不同)，该第二指示信息不包含该第二指示域，或者，该第二指示域保留。
例如，对于工作在授权频段上的小区配置了SUL的终端设备，该第一指示域UL/SUL指示域为1比特，否则为0比特。对于工作在非授权频段上的小区，该第二指示信息不包含该第二指示域(第二指示信息与第一指示信息格式不同)，或者该第二指示域保留为1比特。
在一个实施方式中，在该第一指示信息和该第二指示信息是用于调度PUSCH的第二下行控制信息，即第一指示信息和该第二指示信息的格式相同，都为DCI format0_1(由C-RNTI/CS-RNTI/半持续信道状态信息RNTI(SP-CSI-RNTI)/MCS-C-RNTI进行CRC加扰)时，或者该第二指示信息的格式与该第一指示信息的格式不同时(例如第一下行控制信息的格式是DCI format 0_1，第二下行控制信息的格式是新设计的DCI format)，该第二指示信息不包含该第二指示域。
或者，针对工作在非授权频段的终端设备，该第二指示域为0比特，针对工作在授权频段且被配置了第二上行的终端设备，该第一指示域为1比特，针对工作在授权频段且未被配置第二上行的终端设备，或者针对工作在授权频段且被配置了第二上行且小区仅PUCCH载波被配置于PUSCH传输的终端设备，该第一指示域为0比特；
或者，针对工作在非授权频段的终端设备，该第二指示域为1比特，针对工作在授权频段且被配置了第二上行的终端设备，该第一指示域为1比特，针对工作在授权频段且未被配置第二上行的终端设备，该第一指示域为0比特，针对工作在授权频段且被配置了第二上行且小区仅PUCCH载波被配置于PUSCH传输的终端设备，该第一指示域为0比特。
例如，该第一指示域和第二指示域为该指示域UL/SUL indicator时，针对工作在非授权频段上的小区服务的终端设备，或者工作在授权频段上的小区且未配置SUL的终端设备，或者工作在授权频段上的小区且配置了SUL，但小区仅物理上行控制信道PUCCH载波被配置于物理上行共享信道PUSCH传输的终端设备，该指示域UL/SUL indicator为0比特，针对工作在授权频段上的小区且配置了SUL的终端设备，该指示域UL/SUL indicator为1比特。
或者，例如，该第一指示域和第二指示域为该指示域UL/SUL indicator时，针对工作在授权频段上的小区服务的终端设备，或者工作在授权频段上的小区且配置了SUL，但小区仅物理上行控制信道PUCCH载波被配置于物理上行共享信道PUSCH传输的终端设备，该指示域UL/SUL indicator为0比特，针对工作在授权频段切配置了SUL的终端设备，或者工作在非授权频段上的小区的终端设备，该指示域UL/SUL indicator为1比特，该比特值为0表示NUL或非授权频段上的小区。
或者，例如，对于工作在非授权频段上的小区，该第二指示信息不包含该第二指示域(第二指示信息与第一指示信息格式不同)。
在本实施例中，针对上述图2A-2B中的方法，针对工作在非授权频段的终端设备，网络设备可以不为该终端设备配置第二上行(例如SUL)，即非授权频段上的小区可以看作未配置第二上行的小区。
在一个实施方式中，在参数(例如，FrequencyInfoUL)配置时，例如，在上行频率工作在非授权频段上时，预定义的第一域存在条件描述信息(例如，FDD-OrSUL)描述为该第一域不存在，该第一域可以是频带列表域frequencyBandList、绝对频率位 置A域absoluteFrequencyPointA等，FDD-OrSUL是描述第一域存在的条件。
例如，在FrequencyInfoUL是非授权频段(for a unlicensed band)时，该第一域是不存在(absent)的。或者，该第一域只有在FrequencyInfoUL是成对的上行(对应FrequencyInfoDL的DL)，或者FrequencyInfoUL是SUL时，强制存在，在其他情况下，不存在。
在一个实施方式中，在参数配置时，SRS载波切换参数信息srs-SwitichFromCarrier(表示从哪一个SRS载波进行SRS载波切换)为可选的optional，Need M，或者是条件存在的，例如该条件以Cond IN表示，Cond IN可以描述为在该终端设备工作在授权频段上或被配置了第二上行时，该SRS载波切换参数信息必须存在，否则不存在(mandatory present if SUL is configured or if ul carrier is for licensed band.It is absent otherwise)。
在本实施例中，该方法还可以包括(可选，未图示)：该终端设备向网络设备指示能力信息，该能力信息表示该终端设备是否具备交织能力，其中，该能力可以是针对每个UE(per UE)，也可以是针对每个频率范围(FR，Freqency Range)，即per FR。该终端设备可以支持FR1和FR2，FR1目前是指450M～6GHz，FR2目前是指24250MHz～52600MHz；per FR意味着对于一个终端设备，可能支持FR1上的交织，但不支持FR2上的交织，而per UE意味着对于一个终端设备，如果支持交织，就表示FR1和FR2都支持，否则都不支持。
在本实施例中，该能力信息可以在终端设备能力传递(UE capability transfer)过程中由UECapabilityInformation消息承载；或该能力信息在终端设备辅助信息(UE Assistance Information)过程中由无线链路控制RRC消息UEAssistanceInformation承载。本实施例并不以此作为限制。
在本实施例中，该终端设备可以总是包括该能力信息；或者可以基于网络设备的指示，确定是否传递该能力信息，在网络设备要求的情况下传递，否则不传递。网络设备指示该能力信息是否传递的指示信息可以包括在RRC消息UECapabilityEnquiry或RRC消息RRCReconfiguration消息里，或者包括在系统消息里，例如MIB，SIB1、SIB2或SIB3等。
由于针对工作在非授权频段的上行，包括PUSCH、PUCCH和PRACH的上行波形，可以使用交织机制，以增强给定功率谱密度限制的场景，使得上行发送功率增加， 从而扩大了上行覆盖，则不需要SUL作为补充。
通过上述实施例，通过不使用(不配置)SUL，使终端设备使用频谱效率高的NUL，从而能够避免终端设备错误的使用不合适的上行载波，提高服务小区的吞吐量。另外，对标准的修改小，实现简单，从而节约产品的成本。
实施例2
在现有的授权频段，当服务小区发起随机接入过程，且在服务小区配置了SUL时，可以使用服务小区的下行作为下行路损参考，将下行路损参考的参考信号接收功率(RSRP)的值与阈值进行比较，并根据比较结果选择SUL或NUL；但在非授权频段上，服务小区上发起了随机接入过程时，使用非授权频段的下行载波作为下行路损参考，考虑到网络侧LBT失败的影响，终端设备对下行路损参考的RSRP的测量结果可能比实际的无线链路情况差，这使得原本应该使用NUL的终端错误地选择了SUL。
在本实施例中，提供一种上行选择方法，该方法与实施例1不同之处在于，针对工作在非授权频段的终端设备，仍然可以为终端设备配置SUL，但使用工作在授权频段上的下行作为下行路损参考，使得测得的参考信号接收功率(RSRP)能更准确地反映无线链路情况，从而能够避免终端设备错误的使用不合适的上行载波，提高服务小区的吞吐量。
图3是本实施例2的上行选择方法流程图，应用于工作在非授权频段上的小区服务的终端设备侧。如图3所示，该方法包括：
步骤301，该终端设备确定下行路损参考(downlink loss reference)的参考信号接收功率；
步骤302，该终端设备根据该参考信号功率的值选择第一上行或第二上行；
其中，该下行路损参考的频率在授权频段内。
在本实施例中，在步骤301中，该小区与下行路损参考的关联方法可以是小区级的或者载波级的，即下行路损参考的频率在授权频段内包括：使用工作在授权频段的第一小区的下行作为该下行路损参考，或者使用授权频段的第一载波作为该下行路损参考。
例如，该下行路损参考是授权频段的第一小区的下行时，该第一小区可以是预配 置或预定义或终端设备自主选择的。
在一个实施方式中，该第一小区可以是预定义的，可以预定义该第一小区是该授权频段主小区或者工作在与该非授权频段同一频带内的授权频段上的小区，在授权频段的主小区与非授权频段辅小区载波聚合的情况下，将该授权频段主小区的下行作为非授权频段辅小区(上行)的下行路损参考，或者将任意一个工作在与该非授权频段同一频带内的授权频段上的小区的下行作为非授权频段辅小区(上行)的下行路损参考。终端设备可以直接根据预定义的第一小区的下行作为该下行路损参考。
在一个实施方式中，该第一小区可以是预配置的，可以预配置该第一小区是该授权频段主小区或者特殊小区或者工作在与该非授权频段同一频带内的授权频段上的小区，该方法还可以包括：(未图示)该终端设备接收网络设备发送的配置信息，该配置信息用于指示该下行路损参考，该下行路损参考是授权频段内的一个频率，其中，该配置信息包括工作在授权频段的第一小区标识，根据该第一小区标识隐式的指示该下行路损参考，由于该第一小区工作在授权频段，该终端设备根据配置信息中的第一小区标识即确定该下行路损参考。该终端设备通过广播信息或专用信令接收该配置信息。
在一个实施方式中，该第一小区是工作在与该非授权频段同一频带内的授权频段上的小区，该终端设备可以自主选择工作在与该非授权频段同一频带内的授权频段上的一个小区，将该选择的小区的下行作为下行路损参考。
例如，该下行路损参考是授权频段的第一载波时，该第一载波可以是预配置或预定义或终端设备自主选择的。该第一载波是频分双工FDD下行载波或时分双工TDD载波(上下行公用同一载波)。
在一个实施方式中，该第一载波可以是预定义的，可以预定义该第一载波是与该非授权频段同一频带内的授权频段上的FDD下行载波或TDD载波，将与该非授权频段同一频带内的授权频段上的FDD下行载波或TDD载波作为非授权频段小区(上行)的下行路损参考。终端设备可以直接根据预定义的第一载波作为该下行路损参考。
在一个实施方式中，该第一载波可以是预配置的，可以预配置该第一载波是辅助下行载波SDL，该SDL是授权频段的载波，或者，该方法还可以包括：(未图示)该终端设备接收网络设备发送的配置信息，该配置信息用于指示该下行路损参考，该下行路损参考是授权频段内的一个频率，其中，该配置信息包括授权频段的第一载波标 识，根据该第一载波标识隐式的指示该下行路损参考，由于该第一载波是授权频段上的，该终端设备根据配置信息中的第一载波标识即确定该下行路损参考。例如，可以使用绝对无线频道编号ARFCN指示该第一载波标识，该配置信息可以包含在小区相关的信息元中，例如ServingCellConfig，或者可以包含在信道/参考信号相关的信息元中，例如RACH-ConfigCommon、PUCCH-PowerControl、PUSCH-PowerControl、SRS-Config，本实施例并不以此作为限制，该终端设备通过广播信息或专用信令接收该配置信息。
在一个实施方式中，该第一载波是与该非授权频段同一频带内的授权频段上的FDD下行载波或TDD载波，该终端设备可以自主选择与该非授权频段同一频带内的授权频段上的一个FDD下行载波或TDD载波作为下行路损参考。
在本实施例中，该终端设备的下行路损参考与该小区的其他终端设备的下行路损参考相同或不同。该小区的至少两种类型的上行信道或参考信号的下行路损参考相同或不同。
在一个实施方式中，该下行路损参考适用于一个小区下所有终端设备的上行，其中，可以适用于所有上行，包括所有上行信道和上行参考信号，或者该适用于特定上行，包括所有上行信道和上行参考信号，例如上行控制信道、上行共享信道、探测参考信号和随机接入信道等上行信道和上行参考信号中的至少两个可以有相同或不同的下行路损参考。
在一个实施方式中，该下行路损参考适用于该特定终端设备的上行，其中，可以适用于所有上行，包括所有上行信道和上行参考信号，或者该适用于特定上行，包括所有上行信道和上行参考信号，例如上行控制信道、上行共享信道、探测参考信号和随机接入信道等上行信道和上行参考信号中的至少两个可以有相同或不同的下行路损参考。
在本实施例中，例如在接收配置信息时，如果通过广播信息接收，该下行路损参考适用于一个小区下所有终端设备的上行；如果通过专用信令接收，该下行路损参考适用于该特定终端设备的上行，但本实施例并不以此作为限制。
在本实施例中，在确定作为路损参考的下行后，在步骤301中，可以确定该下行路损参考的参考信号接收功率，具体确定方法可以参考现有技术，例如对下行参考信号进行测量，得到RSRP，因此，该方法还可以包括：(可选，未图示)该终端设备 接收网络设备发送的用于计算路损值的参考信号标识，该参考信号标识(ID)可以是信道状态信息参考信号(CSI-RS，Channel State Information Reference Signal)ID或同步信号块(SSB，Synchronizing Signal Block)ID，其可以包含在测量配置信息中发送，具体可以参考现有技术。
在本实施例中，在步骤302中，在该小区发起随机接入过程时，在该终端设备未被通知用于随机接入过程的载波，且该小区配置了该第二上行，且该参考信号接收功率小于阈值时，该终端设备选择该第二上行；在该终端设备未被通知用于随机接入过程的载波，且该小区配置了该第二上行，且该参考信号接收功率不小于阈值时，该终端设备选择该第一上行，该阈值可以根据需要确定，本实施例并不以此作为限制。
通过上述实施例，使用工作在授权频段上的下行作为下行路损参考，使得测得的参考信号接收功率(RSRP)能更准确地反映无线链路情况，从而保证终端设备正确地选择上行，实现与授权频段相同的小区吞吐量。并且，该上行选择方法实现简单，对标准影响较小，可以节约产品的成本，尤其是对于连接态的终端设备，该上行选择方法能够达到更好的效果。
实施例3
在现有的授权频段，当服务小区发起随机接入过程，且在服务小区配置了SUL时，可以使用服务小区的下行作为下行路损参考，将下行路损参考的参考信号接收功率(RSRP)的值与阈值进行比较，并根据比较结果选择SUL或NUL；但在非授权频段上，服务小区上发起了随机接入过程时，使用非授权频段的下行载波作为下行路损参考，考虑到网络侧LBT失败的影响，终端设备对下行路损参考的RSRP的测量结果可能比实际的无线链路情况差，这使得原本应该使用NUL的终端错误地选择了SUL。
由于LBT成功/失败与信道负荷相关，当信道负荷小时，LBT成功率高，反之LBT成功率低。因此，在本实施例中，提供一种上行选择方法，该方法与实施例1，2的不同之处在于，仍然可以为终端设备配置SUL，但在上行选择时，考虑信道负荷的影响。
图4是本实施例3的上行选择方法流程图，应用于终端设备侧。如图4所示，该方法包括：
步骤401，终端设备获取信道状态测量量(metric)的信息；
步骤402，根据该测量量的信息选择第一上行或第二上行。
在本实施例中，该信道状态测量量包括以下测量量的至少一种：信道占有率，信道忙率，接收信号强度指示RSSI，LBT失败相关测量测量量，LBT成功相关测量量等。其中，该测量量的信息可以是测量量的测量结果，根据该测量结果可以确定信道/小区负荷的高低级别，或者该测量量的信息可以表征信道/小区负荷高低级别，信道/小区负荷高低级别可以表示为：高、低或者负荷百分比等。
例如，信道占有率表示一段时间内(例如当前子帧的前后1000个子帧时间内)传输或授权了的资源数(例如子信道数)与传输池里配置的资源总数之间的比值；信道忙率表示，通过对配置的传输池中的资源的测量量进行测量，结果高于阈值的资源占总配置资源的比例；LBT失败/成功相关测量测量量表示LBT失败或成功率(次数比)，例如LBT失败率可以是进行LBT后认为信道忙碌不进行传输的次数与LBT总次数的比例，以上信道状态测量量仅为示例，本实施例并不以此作为限制，例如，该信道状态测量量还可以是表示信道占用或媒介竞争的新的测量量等。其中，信道占有率越低、信道忙率越高、RSSI值越大、LBT失败率越大、或LBT成功率越小表示信道/小区负荷越大。
在本实施例中，在步骤401中，该信道状态测量量的测量可以在终端设备侧进行，即该终端设备测量该信道状态测量量，以获取该测量量的信息，或者，该终端设备接收网络设备发送的信道状态测量量相关的参数的值，以获取该信道状态测量量的信息。
在本实施例中，在步骤402中，该终端设备可以将测量量的信息与阈值进行比较，根据比较结果选择第一上行或第二上行。上述第一上行和第二上行可以是小区特定的或者是信道或参考信号特定的。
在本实施例中，终端设备可以根据测量量的信息，或者测量量的信息与RSRP两者结合，选择第一上行或第二上行。
在一个实施方式中，可以将该测量量的信息与各量对应的阈值进行比较，在比较结果满足第一预定条件时，选择第一上行，在比较结果满足第二预定条件时，选择第二上行；或者在比较结果满足第二预定条件时，根据下行路损参考的参考信号接收功率选择第一上行或第二上行。
例如，在测量量为信道忙率时，将获取的信道状态测量量的信息与信道忙率阈值进行比较，在比较结果为大于第一阈值(第一预定条件)时，表示当前信道/小区负荷较高，终端设备选择第一上行，在不大于第一阈值或者不大于第二阈值(第二预定条件)时，表示当前信道/小区负荷较低，终端设备选择第二上行，或者，在不大于第一阈值或者不大于第一阈值且大于第二阈值(第二预定条件)时，根据RSRP选择第一上行或第二上行。例如将测量得到的RSRP与阈值比较，在RSRP小于RSRP阈值时，选择第一上行，在RSRP不小于RSRP阈值时，选择第二上行，其中，第一阈值大于第二阈值，由此，可以保证终端设备正确地选择上行，降低了由于网络侧LBT失败导致参考信号未传输对测量造成的影响，使得终端在高负荷的情况下尽量使用NUL，从而保证了与授权频段相似的吞吐量。该上行选择可以适用于物理接入信道PRACH的选择场景等。
例如，在测量量为信道忙率时，将获取的信道状态测量量的信息与信道忙率阈值进行比较，在比较结果为小于第三阈值(第一预定条件)时，表示当前信道/小区负荷较低，终端设备选择第一上行，在不小于第三阈值或者不小于第四阈值(第二预定条件)时，表示当前信道/小区负荷较高，终端设备选择第二上行，或者，在不小于第三阈值或者不小于第三阈值且小于第四阈值(第二预定条件)时，根据RSRP选择第一上行或第二上行。例如将测量得到的RSRP与阈值比较，在RSRP小于RSRP阈值时，选择第一上行，在RSRP不小于RSRP阈值时，选择第二上行，其中，第三阈值小于第四阈值，由此，可以帮助高负荷终端设备使用第二上行，从而实现负载均衡，提升用户体验，避免由于很多终端设备同时工作在相同非授权频段时，终端设备之间竞争资源，导致可能很长时间无法进行上行通信，无法传输反馈信息以及参考信号等，使整个小区都无法工作的问题。该上行选择可以适用于物理上行控制信道PUCCH，或者配置的授权传输或者半持续调度或SRS传输等场景。
以上仅以测量量为信道忙率为例进行说明，本实施例并不以此作为限制，其他测量量的实施方式与信道忙率类似，或者也可以结合至少两个测量量的信息的比较结果确定信道/小区负荷的高低，此处不再一一赘述。
在一个实施方式中，可以将下行路损参考的参考信号接收功率与其对应的阈值进行比较，在比较结果满足第三预定条件时，将该测量量的信息与各量对应的阈值进行比较，在比较结果满足第四预定条件时，选择第一上行，在比较结果满足第五预定条 件时，选择第二上行。
例如，将测量的RSRP与RSRP阈值进行比较，在RSRP小于RSRP阈值或者小于RSRP第一阈值且大于RSRP第二阈值(第三预定条件，RSRP第一阈值大于RSRP第二阈值)时，在测量量为信道忙率时，将获取的信道状态测量量的信息与信道忙率阈值进行比较，在比较结果为大于第五阈值(第四预定条件)时，表示当前信道/小区负荷较高，终端设备选择第一上行，在比较结果是不大于第五阈值(第五预定条件)时，表示当前信道/小区负荷较低，终端设备选择第二上行，在RSRP不小于RSRP阈值或者不小于RSRP第一阈值时，终端设备选择第一上行，在RSRP不大于RSRP第二阈值时，终端设备选择第二上行，由此，可以保证终端设备正确地选择上行，降低了由于网络侧LBT失败导致参考信号未传输对测量造成的影响，使得终端在高负荷的情况下尽量使用NUL，从而保证了与授权频段相似的吞吐量。该上行选择可以适用于物理接入信道PRACH的选择场景等。
例如，测量的RSRP与RSRP阈值进行比较，在RSRP大于RSRP阈值(第三预定条件)时，在测量量为信道忙率时，将获取的信道状态测量量的信息与信道忙率阈值进行比较，在比较结果为大于第六阈值(第五预定条件)时，表示当前信道/小区负荷较高，终端设备选择第二上行，在比较结果是不大于第六阈值(第四预定条件)时，表示当前信道/小区负荷较低，终端设备选择第一上行，在RSRP不大于RSRP阈值时，终端设备选择第二上行，由此，可以帮助高负荷终端设备使用第二上行，从而实现负载均衡，提升用户体验，避免由于很多终端设备同时工作在相同非授权频段时，终端设备之间竞争资源，导致可能很长时间无法进行上行通信，无法传输反馈信息以及参考信号等，使整个小区都无法工作的问题。该上行选择可以适用于物理上行控制信道PUCCH，或者配置的授权传输或者半持续调度或SRS传输等场景。
以上仅以测量量为信道忙率为例进行说明，本实施例并不以此作为限制，其他测量量的实施方式与信道忙率类似，或者也可以结合至少两个测量量的信息的比较结果确定信道/小区负荷的高低，此处不再一一赘述。
在一个实施方式中，可以将下行路损参考的参考信号接收功率与其对应的阈值进行比较，并将该测量量的信息与各量对应的阈值进行比较，在比较结果满足第六预定条件时，选择第一上行；或者在比较结果满足第七预定条件时，选择第二上行。
例如，测量的RSRP与RSRP阈值进行比较，在测量量为信道忙率时，将获取的 信道状态测量量的信息与信道忙率阈值进行比较，在比较结果为表示当前信道/小区负荷较高且RSRP大时，终端设备选择第一上行，否则选择第二上行；或者在比较结果为表示当前信道/小区负荷较低且RSRP小时，终端设备选择第二上行，否则选择第一上行，由此，可以保证终端设备正确地选择上行，降低了由于网络侧LBT失败导致参考信号未传输对测量造成的影响，使得终端在高负荷的情况下尽量使用NUL，从而保证了与授权频段相似的吞吐量。该上行选择可以适用于物理接入信道PRACH的选择场景等。
例如，测量的RSRP与RSRP阈值进行比较，在测量量为信道忙率时，将获取的信道状态测量量的信息与信道忙率阈值进行比较，在比较结果为表示当前信道/小区负荷较高且RSRP小时，终端设备选择第二上行，否则选择第一上行；或者在比较结果为表示当前信道/小区负荷较低且RSRP大时，终端设备选择第一上行，否则选择第二上行，由此，可以帮助高负荷终端设备使用第二上行，从而实现负载均衡，提升用户体验，避免由于很多终端设备同时工作在相同非授权频段时，终端设备之间竞争资源，导致可能很长时间无法进行上行通信，无法传输反馈信息以及参考信号等，使整个小区都无法工作的问题。该上行选择可以适用于物理上行控制信道PUCCH，或者配置的授权传输或者半持续调度或SRS传输等场景。
在本实施例中，在仅根据测量量的信息选择的上行和仅根据RSRP选择的上行不同时，可以由终端设备确定选择哪个上行，例如，通过预定义的方式等，本实施例并不以此作为限制。
在本实施中，该上行选择方法可以是强制(mandatory)的；也可以是可选的(optional)，例如，由网络设备配置(包括显式配置或隐式配置)、或终端设备自己决定是否应用该方法。网络设备可以通过高层信令、媒体接入控制层的控制单元MAC CE和物理层控制信令的至少一种进行该显示配置，还可以是将某个测量量的阈值指示给终端设备，当其测量结果高于或低于该阈值时，应用该方法。隐式配置可以是网络设备广播或配置了该方法中的参数时，隐式的指示应用该方法；也可以是在满足应用条件时应用该方法，例如，该应用条件是该终端设备使用未授权频段时，此处不再一一举例。
在本实施例中，该方法还可以包括：(可选，未图示)该终端设备接收网络设备发送的用于指示应用该方法的指示信息。
在本实施例中，该方法还可以包括：(可选，未图示)该终端设备接收网络设备发送的阈值配置信息，该阈值配置信息用于配置信道状态测量量的阈值，其中该信道状态测量量的阈值用于该终端设备判断是否应用该上行选择方法，或者在应用该上行选择方法时，该信道状态测量量的阈值用于终端设备判断选择第一上行或第二上行，另外，该阈值的数量和大小可以根据需要确定，本实施例并不以此作为限制，另外，可以为不同类型的信道状态测量量配置与其对应的至少一个阈值。
通过上述实施例，考虑信道状态测量量来确定使用SUL还是使用NUL，由此，可以保证终端设备正确地选择上行，降低了由于网络侧LBT失败导致参考信号未传输对测量造成的影响，使得终端在高负荷的情况下尽量使用NUL，从而保证了与授权频段相似的吞吐量。另外，可以帮助高负荷终端设备使用第二上行，从而实现负载均衡，提升用户体验，避免由于很多终端设备同时工作在相同非授权频段时，终端设备之间竞争资源，导致可能很长时间无法进行上行通信，无法传输反馈信息以及参考信号等，使整个小区都无法工作的问题。
实施例4
本实施例4还提供一种上行配置方法。对应于实施例1中的终端设备侧的上行选择方法，内容相同之处不再重复说明。
图5A是本实施例6的上行配置方法示意图，应用于网络设备侧。如图5A所示，该方法包括：
步骤501，网络设备不为工作在非授权频段上的小区中的终端设备配置第二上行；即非授权频段上的小区可以看作未配置第二上行的小区。
在一个实施方式中，在参数(例如，FrequencyInfoUL)配置时，例如，在上行频率工作在非授权频段上时，预定义的第一域存在条件描述信息(例如，FDD-OrSUL)描述为该第一域不存在，该第一域可以是频带列表域frequencyBandList、绝对频率位置A域absoluteFrequencyPointA等，FDD-OrSUL是描述第一域存在的条件。
例如，在FrequencyInfoUL是非授权频段(for a unlicensed band)时，该第一域是不存在(absent)的。或者，该第一域只有在FrequencyInfoUL是成对的上行(对应FrequencyInfoDL的DL)，或者FrequencyInfoUL是SUL时，强制存在，在其他情况下，不存在。
在一个实施方式中，在参数配置时，SRS载波切换参数信息srs-SwitichFromCarrier(表示从哪一个SRS载波进行SRS载波切换)为可选的optional，Need M，或者是条件存在的，例如该条件以Cond IN表示，Cond IN可以描述为在该终端设备工作在授权频段上或被配置了第二上行时，该SRS载波切换参数信息必须存在，否则不存在(mandatory present if SUL is configured or if ul carrier is for licensed band.It is absent otherwise)。
在本实施例中，该方法还可以包括：(可选，未图示)网络设备为工作在授权频段上的小区中的终端设备配置第二上行，和/或网络设备为工作在非授权频段上的小区中的终端设备配置第一上行，和/或网络设备为工作在授权频段上的小区中的终端设备配置第一上行。
图5B是本实施例6的上行配置方法示意图，应用于网络设备侧。如图5B所示，该方法包括：
步骤501'，网络设备向终端设备发送指示信息；该指示信息包含或不包含上行参数相关的指示域；
其中，该网络设备工作在授权频段时，发送的该指示信息为第一指示信息，该指示域为第一指示域，该第一指示信息包含该第一指示域，该网络设备工作在非授权频段时，发送的该指示信息为第二指示信息，该指示域为第二指示域，该第二指示信息包含该第二指示域，或者不包含该第二指示域。该第一指示信息，第二指示信息，第一指示域，第二指示域的具体实施方式可以参考实施例1中步骤201'，此处不再赘述。
在本实施例中，该方法还可以包括(可选，未图示)，网络设备接收终端设备在配置的上行上发送的信令和/或数据和/或信号。
通过上述实施例，通过不使用(不配置)SUL，使终端设备使用频谱效率高的NUL，从而能够避免终端设备错误的使用不合适的上行载波，提高服务小区的吞吐量。另外，对标准的修改小，实现简单，从而节约产品的成本。
实施例5
本实施例5还提供一种信息配置方法。对应于实施例2中的终端设备侧的上行选择方法，内容相同之处不再重复说明。
图6是本实施例5的信息配置方法示意图，应用于工作在非授权频段上的小区服 务的网络设备侧。如图6所示，该方法包括：
步骤601，该网络设备广播该小区的信息；
步骤602，该网络设备发送配置信息，该配置信息指示授权频段内的下行路损参考。
在本实施例中，该小区的信息包括系统帧号(system frame number，SFN)、子载波间隔(subcarrier spacing，SCS)等，具体可以参考现有技术，此处不再赘述。
在本实施例中，该配置信息包括工作在授权频段的第一小区标识或第一载波标识，根据该第一小区标识或第一载波标识隐式的指示该下行路损参考，由于该第一小区或第一载波工作在授权频段，工作在非授权频段上的小区服务的终端设备根据配置信息中的第一小区标识或第一载波标识即确定该下行路损参考是授权频段内的一个频率。该网络设备通过广播信息或专用信令发送该配置信息。该配置信息的具体实施方式可以参考实施例2，此处不再赘述。
通过上述实施例，终端设备根据该配置信息确定使用工作在授权频段上的下行作为下行路损参考，使得测得的参考信号接收功率(RSRP)能更准确地反映无线链路情况，从而保证终端设备正确地选择上行，实现与授权频段相同的小区吞吐量。并且，该上行选择方法实现简单，对标准影响较小，可以节约产品的成本，尤其是对于连接态的终端设备，该上行选择方法能够达到更好的效果。
实施例6
本实施例6还提供一种信息配置方法。对应于实施例3中的终端设备侧的上行选择方法，内容相同之处不再重复说明。
图7是本实施例6的信息配置方法示意图，应用于网络设备侧。如图7所示，该方法包括：
步骤701，网络设备向终端设备发送阈值配置信息，该阈值配置信息用于配置信道状态测量量的阈值，其中，该信道状态测量量的阈值用于该终端设备判断选择第一上行或第二上行。
在本实施例中，该阈值配置信息，该第一上行、第二上行、信道状态测量量的含义请参考实施例3，此处不再赘述。
在本实施例中，该方法还可以包括(可选)：
步骤702，网络设备向该终端设备发送该信道状态测量量相关的参数的值。
在本实施例中，并不限定步骤701和步骤702执行的先后顺序。
通过上述实施例，考虑信道状态测量量来确定使用SUL还是使用NUL，由此，可以保证终端设备正确地选择上行，降低了由于网络侧LBT失败导致参考信号未传输对测量造成的影响，使得终端在高负荷的情况下尽量使用NUL，从而保证了与授权频段相似的吞吐量。另外，可以帮助高负荷终端设备使用第二上行，从而实现负载均衡，提升用户体验，避免由于很多终端设备同时工作在相同非授权频段时，终端设备之间竞争资源，导致可能很长时间无法进行上行通信，无法传输反馈信息以及参考信号等，使整个小区都无法工作的问题。
实施例7
本实施例7还提供一种上行选择装置。由于该装置解决问题的原理与实施例1的方法类似，因此其具体的实施可以参考实施例1的方法的实施，内容相同之处不再重复说明。
图8A是本实施例9的上行选择装置示意图。应用于终端设备，如图8A所示，装置810包括：
处理单元811，其用于执行随机接入过程；
其中，该终端设备工作在非授权频段时，处理单元811执行随机接入过程使用的参数，与该该终端设备工作在授权频段时，处理单元811执行随机接入过程中使用的参数相同。
在本实施例中，该处理单元811的实施方式可以参考步骤201，此处不再赘述。
在一个实施方式中，该参数为上行载波时，该参数相同表示：终端设备工作在非授权频段时，处理单元811使用授权频段上的第一上行载波执行随机接入过程。
在一个实施方式中，该参数为上行载波类型标识时，该参数相同表示：
终端设备工作在非授权频段时，处理单元811在计算RA-RNTI时，不考虑上行载波类型标识，或者计算公式为RA-RNTI＝1+s_id+14×t_id+14×80×f_id，或者在该终端设备工作在授权频段时，处理单元811将执行随机接入过程中选择第一上行载波时的上行载波类型标识的值作为该上行载波类型标识的值；其中，t_id为时域索引，f_id和s_id为频域索引。
图8B是本实施例9的上行选择装置示意图。应用于终端设备，如图8B所示，装置820包括：
接收单元821，其用于接收网络设备发送的指示信息；该指示信息包含或不包含上行参数相关的指示域；
其中，该终端设备工作在授权频段时，接收单元821接收到的该指示信息为第一指示信息，该指示域为第一指示域，该第一指示信息包含该第一指示域，该终端设备工作在非授权频段时，接收单元821接收到的该指示信息为第二指示信息，该指示域为第二指示域，该第二指示信息包含该第二指示域，或者不包含该第二指示域。
该第一指示信息，第二指示信息，第一指示域，第二指示域的具体实施方式可以参考实施例1中步骤201'，此处不再赘述。
在本实施例中，针对上述图8A-8B中的装置，针对工作在非授权频段的终端设备，网络设备可以不为该终端设备配置第二上行(例如SUL)，即非授权频段上的小区可以看作未配置第二上行的小区。
在一个实施方式中，在参数(例如，FrequencyInfoUL)配置时，例如，在上行频率工作在非授权频段上时，预定义的第一域存在条件描述信息(例如，FDD-OrSUL)描述为该第一域不存在，该第一域可以是频带列表域frequencyBandList、绝对频率位置A域absoluteFrequencyPointA等，FDD-OrSUL是描述第一域存在的条件。
例如，在FrequencyInfoUL是非授权频段(for a unlicensed band)时，该第一域是不存在(absent)的。或者，该第一域只有在FrequencyInfoUL是成对的上行(对应FrequencyInfoDL的DL)，或者FrequencyInfoUL是SUL时，强制存在，在其他情况下，不存在。
在一个实施方式中，在参数配置时，SRS载波切换参数信息srs-SwitichFromCarrier(表示从哪一个SRS载波进行SRS载波切换)为可选的optional，Need M，或者是条件存在的，例如该条件以Cond IN表示，Cond IN可以描述为在该终端设备工作在授权频段上或被配置了第二上行时，该SRS载波切换参数信息必须存在，否则不存在(mandatory present if SUL is configured or if ul carrier is for licensed band.It is absent otherwise)。
在本实施例中，该装置还可以包括(可选，未图示)：指示单元，其用于向网络设备指示能力信息，该能力信息表示该终端设备是否具备交织能力，其中，该能力可 以是针对每个UE(per UE)，也可以是per FR。
由于针对工作在非授权频段的上行，包括PUSCH、PUCCH和PRACH的上行波形，可以使用交织机制，以增强给定功率谱密度限制的场景，使得上行发送功率增加，从而扩大了上行覆盖，则不需要SUL作为补充。
通过上述实施例，通过不使用(不配置)SUL，使终端设备使用频谱效率高的NUL，从而能够避免终端设备错误的使用不合适的上行载波，提高服务小区的吞吐量。另外，对标准的修改小，实现简单，从而节约产品的成本。
实施例8
本实施例8还提供一种上行选择装置。由于该装置解决问题的原理与实施例2的方法类似，因此其具体的实施可以参考实施例2的方法的实施，内容相同之处不再重复说明。

在本实施例中，该小区与下行路损参考的关联方法可以是小区级的或者载波级的，即下行路损参考的频率在授权频段内包括：使用工作在授权频段的第一小区的下行作为该下行路损参考，或者使用授权频段的第一载波作为该下行路损参考。

在本实施例中，例如在接收配置信息时，如果通过广播信息接收，该下行路损参考适用于一个小区下所有终端设备的上行；如果通过专用信令接收，该下行路损参考适用于该特定终端设备的上行，但本实施例并不以此作为限制。
在本实施例中，在确定作为路损参考的下行后，确定单元901可以确定该下行路损参考的参考信号接收功率，具体确定方法可以参考现有技术，例如对下行参考信号进行测量，得到RSRP，因此，该装置还可以包括：第二接收单元(可选，未图示)，该第二接收单元还可以用于接收网络设备发送的用于计算路损值的参考信号标识，该参考信号标识(ID)可以是信道状态信息参考信号(CSI-RS，Channel State Information Reference Signal)ID或同步信号块(SSB，Synchronizing Signal Block)ID，其可以包含在测量配置信息中发送，具体可以参考现有技术。
在本实施例中，选择单元902在该小区发起随机接入过程时，在该终端设备未被通知用于随机接入过程的载波，且该小区配置了该第二上行，且该参考信号接收功率 小于阈值时，选择该第二上行；在该终端设备未被通知用于随机接入过程的载波，且该小区配置了该第二上行，且该参考信号接收功率不小于阈值时，选择该第一上行，该阈值可以根据需要确定，本实施例并不以此作为限制。
通过上述实施例，使用工作在授权频段上的下行作为下行路损参考，使得测得的参考信号接收功率(RSRP)能更准确地反映无线链路情况，从而保证终端设备正确地选择上行，实现与授权频段相同的小区吞吐量。并且，该上行选择方法实现简单，对标准影响较小，可以节约产品的成本，尤其是对于连接态的终端设备，该上行选择方法能够达到更好的效果。

通过上述实施例，考虑信道状态测量量来确定使用SUL还是使用NUL，由此，可以保证终端设备正确地选择上行，降低了由于网络侧LBT失败导致参考信号未传输对测量造成的影响，使得终端在高负荷的情况下尽量使用NUL，从而保证了与授权频段相似的吞吐量。另外，可以帮助高负荷终端设备使用第二上行，从而实现负载均衡，提升用户体验，避免由于很多终端设备同时工作在相同非授权频段时，终端设备之间竞争资源，导致可能很长时间无法进行上行通信，无法传输反馈信息以及参考信号等，使整个小区都无法工作的问题。
