Description

一种时域资源配置方法及接入网设备
本申请要求于2018年9月10日提交中国国家知识产权局、申请号为201811052784.7、申请名称为“一种时域资源配置方法及接入网设备”，以及于2018年9月27日提交中国国家知识产权局、申请号为201811134766.3、申请名称为“一种时域资源配置方法及接入网设备”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。
技术领域
本申请涉及通信领域，尤其涉及一种时域资源配置方法及接入网设备。
背景技术
在时分双工(time division duplex，TDD)系统中，保护间隔(GP，guard period)是为了上下行切换设置的保护间隙。若基站的下行传输系统在发送信号的同时，上行传输系统正在接收信号，由于TDD采用上下行同频传输，则上行传输系统会受到严重的干扰。同时，从发变为收，发射机的功率不是能马上消失的，而是存在一个下降过程，这个时间内是无法工作的；同理，从收变为发也是如此，发射机把功率提上来也是需要时间的，这个时间内也是无法工作的。
GP的长度可以配置，若配置合理，GP可以有效地避免上下行信号之间的干扰。其中，GP配置与小区的半径有关，即GP的配置与小区的覆盖范围有关。长期演进(long term evolution，LTE)系统中，协议TS36.213定义了不同的特殊子帧配置比下GP的长度，对应小区的理论最大覆盖范围是5km～100km，如下述表1所示，可以根据实际应用场景选择不同的GP配置。
Figure PCTCN2019105053-appb-000001
Figure PCTCN2019105053-appb-000002
表1
可以理解的是，DwPTS为下行导频时隙，英文全称为downlink pilot time slot，RTDmax＝GP*(1/30.72us)-17-20，理论最大覆盖距离＝3*10e8*RTDmax/2。
LTE系统中的GP配置为一种小区级的静态配置。例如：现网中95％以上的基站选择特殊子帧配置比为7。为了规避大气波导带来的干扰问题，少量基站选择特殊子帧配置比为5。该GP配置对所有终端设备适用，并且一般情况下不会变化。
在新空口(new radio，NR)系统中，协议支持时域资源的灵活配置，但是如何为终端配置合适的GP资源称为一个亟待解决的问题。

具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，都应当属于本申请保护的范围。
本申请实施例提供的通信系统包括接入网设备和至少一个终端设备，其中该接入网设备可以与该至少一个终端设备通信。例如，如图1所示，接入网设备包括接入网 设备101，至少一个终端设备包括终端设备102和终端设备103，终端设备102与接入网设备101通信，终端设备103与接入网设备101通信。需要说明的是，在如图1所述的通信系统所包含的接入网设备和终端设备仅是一种示例，在本申请实施例中，所述通信系统包含的网元的类型、数量，以及网元之间的连接关系不限于此。
接入网设备可以是接入网侧用于支持终端接入通信系统的设备，例如，可以是LTE系统、下一代(移动通信)(next radio，NR)系统或者授权辅助接入长期演进(authorized auxiliary access long-term evolution，LAA-LTE)系统中的演进型基站(evolutional node B，简称可以为eNB或e-NodeB)宏基站、微基站(也称为“小基站”)、微微基站、接入站点(access point，AP)、传输站点(transmission point，TP)或新一代基站(new generation Node B，gNodeB)等。
终端设备以是一种向用户提供语音或者数据连通性的设备，例如可称为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal)、智能终端等，该终端设备可以经无线接入网(radio access network，RAN)与一个或多个核心网进行通信。例如，终端设备可以是移动电话(或称为“蜂窝”电话)、具有移动终端的计算机等，终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置以及未来NR网络中的终端设备，它们与无线接入网交换语音或数据。对终端设备的说明：本申请中，终端设备还可以包括中继Relay，和基站可以进行数据通信的都可以看为终端设备。
本申请实施例中的通信系统可以为各种通信系统，例如：全球移动通信(global system for mobile communications，GSM)系统、码分多址(code division multiple access，CDMA)系统、宽带码分多址(wideband code division multiple access，WCDMA)系统、通用分组无线业务(general packet radio service，GPRS)、长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、通用移动通信系统(universal mobile telecommunication system，UMTS)、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)等。
在新空口(new radio，NR)系统中，接入网设备可以按照下行资源-灵活资源-上行资源的形式为终端配置时域资源。例如，接入网设备可以通过下发时域资源配置信息为终端配置时域资源，该时域资源配置信息可以指示下行资源-灵活资源-上行资源，该时域资源配置信息可以是小区级半静态配置信息、用户级半静态信息和用户级动态信息中的一种或者多种，其中，灵活资源可以用于保护间隔(GP，guard period)的配置，GP可以理解为用于上下行切换之间的保护间隔。GP资源可以称为未知资源或者灵活(Flexible)资源，GP符号可以称为灵活符号。
例如，小区级半静态配置信息配置的时域资源由X，x1，x2，y1和y2这5个参数来定义。如图2所示，为小区级半静态配置信息的示意图。其中X表示配比周期，x1表示配比周期内连续的全下行(D)时隙个数，x2表示x1个全下行时隙后面的下行链路(down link，DL)符号个数；y1表示配比周期内连续全上行(U)时隙个数，y2表示y1个全上行时隙前面的上行链路(up link，UL)符号个数；剩余的符号为未 知(unknown)资源，用户设备(user equipment，UE)级半静态配置信息或用户级动态配置信息进一步将该未知资源配置为下行资源、上行资源或者未知资源，以此来实现动态TDD。
例如，如图3A所示，参考子载波间隔是30kHz，小区级半静态信令可以配置为：X＝2.5ms，x1＝3，x2＝8，y1＝1，y2＝2。那么对于30kHz子载波间隔，2.5ms周期内共5个时隙，其中时隙0、时隙1和时隙2为全D时隙，时隙3的前8个符号为下行符号，时隙3的2个符号为上行符号，时隙3的4个符号为灵活符号，时隙4为全U时隙，时隙3的中间4个符号可以用于GP。
例如，如图3B所示，参考子载波间隔是30kHz，小区级半静态信令可以配置可以配置为：X＝5ms，x1＝7，x2＝6，y1＝2，y2＝4。对于30kHz子载波间隔，5ms周期内共10个时隙，其中前7个时隙，即时隙0、时隙1、时隙2、时隙3、时隙4、时隙5、时隙6为全D时隙；第8个时隙，即时隙7的前6个符号为下行符号，时隙7的后4个符号为上行符号，时隙7的中间4个符号为灵活符号，时隙7的中间4个符号用于GP；最后2时隙，即时隙8和时隙9为全U时隙。
在上述NR技术方案中，GP资源可以通过小区级半静态信令、用户级半静态信令或者用户级动态信息配置。不同终端对GP资源的长度的要求不同，例如，不同终端由于所处的地理位置不同，对GP资源的长度的要求不同。例如，对于大部分近端终端设备来说，因为数据从接入网设备到近端终端设备的所用的时长较短，近端终端设备需要的GP资源的长度短；对于大部分远端终端设备来说，因为数据从接入网设备到远端终端设备的所用的时长较短，近端终端设备需要的GP资源的长度较长。如何为终端配置合适的GP资源是一个亟待解决的问题。
本申请实施例提供了一种方案，可以根据终端的需求，为终端分配GP资源。通过该方案，可以使得终端将GP资源以外的资源用于上行或者下行，提供资源的利用率，例如，对于近端终端设备而言，不需要较多的GP资源，而需要更多的上行时域资源或者下行时域资源，例如，近端终端设备下行多流传输，希望更及时准确的获得信道的信息，需要较多的上行时域资源发送SRS。
下面先对本申请中可能涉及的几个术语进行简单的说明：
小区级半静态配置信息用于指示一个时域资源包括的符号为上行符号、下行符号或者灵活符号，小区级可以理解为该配置信息对小区中的终端有效或者该配置信息可以发送给该小区的终端，半静态可以理解为该配置信息可以通过高层信令下发，该高层信令可以理解为无线资源控制(radio resource control，RRC)层的信令，例如，该高层信令可以是系统消息，接入网设备可以广播系统消息，该系统消息中可以携带小区级半静态配置信息。
用户级半静态配置信息用于指示一个时域资源包括的符号为上行符号、下行符号或者灵活符号，用户级可以理解为该配置信息对特定的终端有效或者该配置信息可以发送给特定终端，半静态可以理解为该配置信息可以通过高层信令下发，高层信令可以理解为无线资源控制(radio resource control，RRC)层的信令，例如该高层信令可以是RRC消息，接入网设备可以向终端发送RRC消息，该RRC消息可以包括终端级半静态配置信息。
用户级动态配置信息用于指示一个时域资源包括的符号为上行符号、下行符号或者灵活符号，用户级可以理解为该配置信息对特定的终端有效或者该配置信息可以发送给特定终端，动态可以理解为该配置信息可以通过物理层信息下发，例如该物理层信令可以是下行控制信息(downlink control information，DCI)，接入网设备可以通过物理下行控制信道(physical downlink control channel，PDCCH)发送该DCI，该DCI可以包括终端级动态配置信息，这里PDCCH可以是组公共(group common，GC)PDCCH。
上述小区级半静态配置信息、用户级半静态配置信息和用户级动态配置信息可以统称为时域资源配置信息。
GP资源，可以称为灵活时域资源或者未知时域资源，GP符号可以称为灵活符号或者未知符。本申请实施例中最大、最小仅仅是一个名称，仅仅为了区分不同名词，并不起限定作用。
下面首先结合图4对本申请实施例提供的技术方案进行说明。图4为本申请实施例提供的一种时域资源的配置方法的示意图。该方法可以用于接入网设备或者接入网设备中的芯片。如图4所示：S401：确定所述终端设备所在小区所需的GP资源。

上面图4中接入网设备可以是接入网设备101，终端设备可以是终端设备102或者终端设备103，便于描述，下面以接入网设备101和终端设备102为例进行介绍。
下面以实施例的方式对本申请技术方案做进一步的说明，如图5A所示，为本申请实施例中时域资源的配置方法的示意图，包括：
S501、接入网设备101确定小区所需的最大GP符号数。
小区所需的最大GP符号数可以理解为保证接入网设备101接收到最远端终端设备的上行信号，最远端终端设备所需的GP符号数，或者，可以理解为保证上下行切换后，接入网设备101能够正确接收最远端终端设备的上行传输信号所需的GP符号数，或者可以理解为所述终端设备与所述接入网设备上下行切换后保证上行同步需要的GP符号数。这里小区可以为接入网设备101提供的1个小区、2个小区或者更多的小区。例如，接入网设备101提供小区1，小区1中终端设备102和终端设备103。最远端终端可以理解为在小区覆盖边缘的终端。
作为第一种实施方式，可以根据小区最大覆盖距离得到确定该最大GP符号数(下面为了表述方便，将小区所需的最大GP符号数称为G_cell)。
作为一种示例，接入网设备101可以根据往返时延(Round Trip Delay，RTD)max＝最大覆盖距离*2/光速得到RTDmax，然后再根据RTDmax＝GP长度-M，得到GP长度，其中，M与终端上下行切换时延和时间提前偏置(TA offset)时延有关，例如，M为终端上下行切换时延和TA offset时延之和，NR中终端上下行切换时延可以是10us，TA offset时延可以是13us，LTE中终端上下行切换时延可以是17us，TA offset时延可以是20us。然后GP长度除以符号的长度可以得到GP符号数目。
例如，下述表2所示，为一种小区最大覆盖距离与最大GP符号数的示例。

表2
在表2所示中，当小区半径<＝1.9km时，对应的最大GP符号数为1符号；当小区半径1.9km<＝7.3km时，对应的最大GP符号数为2符号；当小区半径703<＝12.6时，对应最大的GP符号数为3符号。
作为第二种实施方式，在第一种实施方式的基础上，接入网设备101可以判断是否向该小区的终端设备发送过LTE的上下行子帧配比，若有，接入网设备101根据LTE的上下行子帧配比，确定小区的GP符号数为G3；那么，接入网设备101确定小区的最大GP符号数可以为G_cell＝max{G1，G3}。
作为第三种实施方式，接入网设备101可以判断是否向该小区的终端设备发送过LTE的上下行子帧配比，若有，接入网设备101可以直接根据LTE的上下行子帧配比，确定小区的GP符号数为G3；那么，接入网设备101确定小区的最大GP符号数可以为G_cell＝G3。
可选的，接入网设备101确定小区所需的最大GP符号数后，接入网设备101确定小区所需的最大GP资源。

相应地，终端可以接收小区级半静态配置信息，然后配置GP资源。
S502和S403中的内容可以相互参考。
S503、接入网设备101确定终端设备102所需的最小GP符号数。
终端设备102所需的最小GP符号数可以理解为为保证接入网设备101正确接收来自终端102用户的上行信号，或者，可以理解为保证上下行切换后，接入网设备101能够正确接收终端设备102的上行传输信号所需的GP符号数，或者可以理解为终端设备102与接入网设备101上下行切换后保证上行同步需要的GP符号数。
作为一种实现方式，接入网设备101可以根据终端设备102的上行TA测量结果，确定终端设备102所需的最小GP符号数G2。例如，接入网设备101测量终端设备102发送的上行参考信号，计算该终端设备102的TA测量值TA测量值表示信号从终端设备102到达接入网设备101所需要的单向最小时延，信号从终端设备102到接入网设备101的环回时延为该TA测量值的2倍，可以的，可以再加上终端设备102上下行切换所需要的切换时间和接入网设备101上下行切换所需要的切换时间中的一种或者多种等因素，可以得到保证终端设备102信号环回所需要的最小时间，除以符号长度即可以得到终端设备102所需要的最小GP符号数。
如图5B所示，箭头1代表接入网设备101和终端设备102之间的单向时延，箭头2代表终端设备102的上下行切换所需要的最小时间和接入网设备101的上下行切换所需要的时间，例如接入网设备101的上下行切换所需要的时间可以是时间提前偏置(TA offset)时延。最小GP符号数对应的GP长度可以是2*单向时延(箭头1)+终端设备102的上下行切换所需要的最小时间和接入网设备101的上下行切换所需要的时间(箭头2)。
例如，下述表3所示，为一种终端设备TA测量值与最小GP符号数的示例。

在表3所示中，当TA测量值小于等于21.68us时，终端设备102所需的最小GP符号数为1，当TA测量值大于等于21.68且小于等于57.35时，终端设备102所需的最小GP符号数为2，当TA测量值大于等于57.35且小于等于93.03时，终端设备102所需的最小GP符号数为3。
可选的，在上述实施方式中，初始TA测量值可以通过测量物理随机接入信道(physical random access channel，PRACH)信道中的Preamble序列测量得到。或者，终端设备接入系统后，TA测量值可以通过测量SRS参考信号得到，例如，终端设备在接入系统后，通过测量SRS参考信号可以对初始TA测量值进行调整从而更新TA测量值。
可选的，在上述实施方式中，接入网设备101计算该终端设备102的TA测量值，还可以通过测量物理上行共享信道(physical uplink shared channel，PUSCH)信道上的DMRS(Demodulation RS，解调参考信号)得到。
可选的，接入网设备101确定终端设备102所需的最小GP符号数，可以确定终端设备102所需的最小GP资源。
S503可以与S402相互参考。
S504、接入网设备101根据小区的最大GP符号数和终端设备102所需的最小GP符号数，确定终端设备102新增的上行符号数或者新增的下行符号数。
对于一个终端设备102，接入网设备101可以将最大GP符号数减去最小GP符号数的符号数对应的符号中的部分符号或者全部符号确定为该终端设备102新增的上行符号或者新增的下行符号。
例如，若G_UE小于G_cell，接入网设备101根据系统上下行物理信道和信号物理资源的需求状态，以及最大GP符号数和最小GP符号数确定该终端设备102新增的下行符号或新增的上行符号。
可选的，对于上行资源受限的场景，在S504之后，提供了如下两种实施方式：
S5A05-S5A07为上行资源受限的场景的第一种实施方式：
S5A05、接入网设备101确定可增加的上行符号数后，确定该终端设备102更新的时域资源配置信息。
S5A05可以与S404相互参考。
S5A06、向终端设备102发送更新的时域资源配置信息。
例如，接入网设备101可以通过UE级RRC信令发送时域资源配置，所述时域资源配置指示新增的上行符号。
可选的，对于该终端设备102，接入网设备101在所有可用的上行符号资源上进行物理信道和信号的调度选择。
S5A07、接入网设备101可以通知终端设备102在新增的上行符号(y_add1)上发送参考信号，进行IoT测量。
例如，接入网设备101可以通过DCI信令通知终端设备102。
该参考信号如SRS等。接入网设备101对新增上行符号分别进行干扰噪声(interference over thermal，IoT)测量。
S5A08、若IoT测量值大于某一预先设定门限，不进行上行调度。
由于IoT测量值大于某一预先设定门限，说明该上行符号上受到强干扰，接入网设备101在受到强干扰的上行符号资源上不进行上行物理信道和信号的调度。
可选的，在S5A07中，接入网设备101在配置了新增y_add1符号和原始(y2)符号为上行符号后，接入网设备101还可以指示终端设备102在y_add1符号和y2符号发送参考信号，例如通过RRC信令或者DCI信令通知终端设备102在增加的y_add1和y2符号上发送参考信号，该参考信号如SRS等。接入网设备101可以对上行符号y_add1+y2上进行干扰测量；接入网设备101根据实际测量得到的y_add1+y2上行符号上的IoT测量结果，确定终端设备上行实际能使用的上行符号数。对于该终端设备102，接入网设备101在所有可用的上行符号资源上进行物理信道和信号的调度，接入网设备101在受到强干扰的上行符号资源上不进行上行物理信道和信号的调度选择。即对于y_add1来说，未受强干扰的可用的上行符号数y_add2，对于y2来说，未受强干扰的可用的上行符号数y2_update，该终端设备实际可用的上行符号数y2_new＝y2_update+y_add2。
可选的，在S5A07中，接入网设备101在配置了y_add1符号、y2符号和y1时隙为上行时域资源后，接入网设备101还可以指示终端设备在y_add1符号、y2符号和y1时隙发送参考信号，例如接入网设备101可以通过RRC信令或者DCI信令通知终端设备102在y_add1个符号、y2符号和y1时隙上发送参考信号，该参考信号如SRS等。接入网设备101对所有上行符号进行干扰测量；接入网设备101根据实际测量得到的所有上行符号上的IoT测量结果，确定终端设备上行实际能使用的上行符号数。对于该终端设备102，接入网设备101在所有可用的上行符号资源上进行物理信道和信号的调度，接入网设备101在受到强干扰的上行符号资源上不进行上行物理信道和信号的调度选择。
S5B05-S5B07为上行资源受限的场景的第二种实施方式：
S5B05：接入网设备101可以指示终端设备102在新增的上行符号上发送参考信号，进行IoT测量。
例如，接入网设备101可以通过DCI信令指示终端设备102。
该参考信号如SRS等。接入网设备101对增加的可用上行符号y_add1分别进行干扰噪声(interference over thermal，IoT)测量，若IoT测量值大于某一预先设定门限，则说明该可用上行符号上受到强干扰。统计IoT测量值小于预先设定门限的符号数，得到未受强干扰的可用上行符号数y_add2；该终端设备实际可用的上行符号数y2_new＝y2+y_add2；对于该终端设备102，接入网设备101在所有可用上行符号资源上进行物理信道和信号的调度，接入网设备101在受到强干扰的可用上行符号资源上不进行上行物理信道和信号的调度选择。
需要说明的是，接入网设备101对增加的可用上行符号y_add1进行干扰测量，具体的实现方式如下所示：接入网设备101接收所有有用信号、干扰和热噪声的能量，减去解调后的有用信号能量，即可得到干扰和噪声的能量。
S5B06：接入网设备101确定未受干扰的新增的的上行符号数后，确定该终端设备102更新的的时域资源配置信息。
S5B07、接入网设备101向终端设备102发送更新的时域资源配置信息。
例如，接入网设备101可以通过UE级RRC信令发送时域资源配置信息。
可选的，对于该终端设备102，接入网设备101在所有可用的上行符号资源上进行物理信道和信号的调度选择。可选的，接入网设备101不下发UE级RRC信令，直接通过DCI信令，在强干扰的可用上行符号上不进行上行信道和信号的资源分配。S5B07可以与S404相互参考。
可选的，对于下行受限的场景，本申请实施例提供了如下实施方式：
S5C05：接入网设备101向终端102发送时域资源配置信息，该时域资源配置信息可以指示可用时域资源为下行时域资源。
该时域资源配置信息可以是用户级配置信息，例如用户级半静态配置信息或者用户级动态配置信息。
可用时域资源为最大GP资源中除了最小GP资源以外的部分或者全部资源。
S5C05可以与S404相互参考。
例如，对于终端设备102的下行资源受限场景：上行原有的可用符号数不变，接入网设备101确定该终端设备102可增加的下行符号数x_add＝G_cell–G_UE；该终端设备102实际可用的下行符号数x2_new＝x2+x_add。
例如，对于终端设备102的上行资源受限场景：接入网设备101根据最大GP符号数和最小GP符号数，确定该终端设备102实际可用的下行符号数，具体可以包括：
相应地，对于该终端设备102，接入网设备101在所有可用的下行符号资源上进行下行物理信道和信号的调度选择。
在本申请实施例中，接入网设备101根据当前系统上下行物理信道和信号物理资源的需求状态，以及上行IoT测量结果，确定该终端设备实际可用的下行资源或上行资源。有效利用资源的同时，避免邻区接入网设备101、远端接入网设备101干扰和上下行之间的干扰问题；接入网设备101向终端设备102通知可用的上行符号数或者可用的下行符号数；实现UE级半静态或动态配置的GP和灵活动态的上下行资源分配。
下面结合图6做进一步的说明，图6为本申请实施例中时域资源的配置方法的示意图，如图6所示：
S601：接入网设备101确定小区所需最大的GP符号数。
需要说明的是，步骤S601是可选的步骤。
S602：接入网设备101确定终端设备102所需的最小GP符号数。
步骤S601-S602可以参考上述图5A所示实施例中的步骤S501和S503，此处不再赘述。
S602后，作为第一种实施方式：

该时域资源配置信息可以是用户级半静态或者用户级动态时域资源配置信息，指示最小GP资源。
可选的，该时域资源配置信息可以将目标时域资源配置成上行时域资源或者下行时域资源。
其中，目标时域资源可以是最大GP符号数资源-最小GP符号数资源中的部分或者全部时域资源。
可选的，S6A04：接入网设备101在该上行时域资源上检测得到IoT测量值。
可选的，S6A05：当IoT测量值超过阈值，则接入网设备101在超过阈值的上行时域资源上不进行资源分配。
S602后，作为第二种实施方式：
S6B03：接入网设备101在目标时域资源上进行IoT测量，得到IoT测量值。
其中，目标时域资源可以是最大GP符号数资源-最小GP符号数资源中的部分或者全部时域资源。对于目标时域资源，接入网设备101进行检测干扰，得到IoT测量值，当IoT测量值超过阈值时，接入网设备101确定IoT测量值大于阈值的时域资源，IoT测量值大于阈值的时域资源为受到干扰的资源。
S6B04：接入网设备101向终端设备102发送时域资源配置信息。
该时域资源配置信息可以是用户级半静态或者用户级动态的时域资源配置信息，指示GP资源，其中，该GP资源为最小GP资源+[(最大GP资源-最小GP资源)中受到干扰的资源]。
下面结合图7和图8中的具体的示例作进一步的说明。
如图7所示，为本申请实施例中上下行资源的配置方法的另一个实施例示意图，包括：
701、如果接入网设备101未向小区的终端设备发送过LTE的上下行子帧配比，那么基站根据小区最大覆盖距离，确定小区所需要的最大GP符号数G1。
假设小区最大覆盖距离为14km，小区所需要的最大GP符号数G1＝4符号。
702、接入网设备101根据小区所需要的最大GP符号数G1，确定上下行时域资源配置信息。
以C-band频段NR系统为例来进行说明，该频段所使用的子载波间隔为30kHz，上下行时隙配比周期为2.5ms，则X＝2.5ms。接入网设备101根据上下行业务量确定x1＝3，y1＝1；接入网设备101还根据上行物理信道和信号所需要的资源，如SRS或上行控制信道(physical uplink control channel，PUCCH)，确定上行符号数y2＝2。
如果当前系统中不存在已有LTE的时隙配比，故实际小区需要配置的GP符号数G_cell＝G1＝4符号。那么，对应的下行符号数x2＝14-y2-G_cell＝8。
可以理解的是，也可以是接入网设备101根据下行物理信道和信号需要的资源，确定下行符号数x2＝8；接入网设备101再根据小区最大覆盖距离，确定小区所需要的最大GP符号数G1＝4，如果当前系统中无存量LTE，则G_cell＝G1＝4；那么对应的上行符号数y2＝14-x2-G_cell＝2。
703、接入网设备101通过小区级RRC信令，向小区内的所有终端设备发送上下行时域资源配置信息。
接入网设备101可以通过系统消息块(system information block，SIB1)消息通知小区内的所有终端设备上下行时域资源配置信息，即当前时隙配比信息为：X＝2.5ms，x1＝3，x2＝8，y1＝1，y2＝2。如图8所示，图8为终端设备当前时隙配比的一个示意图。
704、接入网设备101根据终端设备的上行TA测量结果，确定终端设备所需的最小GP符号数。
接入网设备101对某个终端设备的上行物理信道和信号进行IoT测量，如对物理随机接入信道(physical random access channel，PRACH)信道和SRS进行IoT测量，根据IoT测量结果更新该终端设备的TA测量值，根据TA测量值和GP符号的对应关系确定终端设备所需要的最小GP符号数G2。
例如：该终端设备实际TA测量值为50us，根据上述表3所示，则对应最小GP符号数G2＝2符号。那么终端设备所需要配置的GP符号数G_UE＝G2＝2，即2符号。
705、接入网设备101根据当前系统上下行物理信道和信号物理资源需求的状况确定增加上行资源。
接入网设备101根据当前系统上下行物理信道和信号物理资源需求的状况，确定增加上行资源。如当前系统下近点用户SRS资源受限，接入网设备101确定增加上行可用资源，则下行符号数x2固定为8，增加上行可用符号数y_add＝2符号.
706、接入网设备101通过DCI信令，在增加上行资源的符号上发送参考信号，进行IoT测量，得到IoT测量值。
例如：接入网设备101通过DCI信令通知终端设备在时隙(Slot)#3上符号#10和#11以及#12，#13上发送SRS信号。接入网设备101对Slot#3上符号#10～13符号进行IoT测量。
707、接入网设备101根据IoT测量值，确定用于终端设备实际可用的上行符号数。
若这4个符号上的IoT均小于某一门限，则确定这4个符号上均可用于该终端设备的上行发送，该终端设备上行实际可用的符号数为4。若符号#10上的IoT大于某一门限，则只有符号#11～13可用于该终端设备的上行发送，该该终端设备上行实际可用的符号数为3，如上图8所示。
708、接入网设备101向终端设备发送实际可用的上行符号数的指示信息。
接入网设备101通过UE级RRC信令或DCI信令，通知终端设备用于上行传输及下行传输的符号数(如x2＝8，y2_new＝4)，从而使得终端设备确定实际使用到的GP符号数和GP位置。
在本申请实施例中，接入网设备101通过测量得到的TA值和上行IoT测试值，确定终端设备实际所需要的GP符号数及可用的上行符号数，通过小区级SIB1信令和UE级RRC信令相结合的方式，实现UE级GP符号数和上行符号数的半静态或动态配置，实现系统资源的有效利用，提升系统性能。在现有技术中，GP符号个数和位置以及上行符号数目是静态配置的。与现有技术相比，在本申请实施例中，近点终端设备上行符号数增加到4，增加了上行SRS可用资源，有利于系统性能的提升。
如图9所示，为本申请实施例中上下行资源的配置方法的另一个实施例示意图，包括：
901、接入网设备101根据小区最大覆盖距离，确定小区所需要的最大GP符号数 G1。
假设小区最大覆盖距离为14km，小区所需要的最大GP符号数G1＝4符号。
902、如果接入网设备101已向小区的终端设备发送过LTE的上下行子帧配比，则接入网设备101根据LTE的上下行子帧配比，确定小区的GP符号数为G3。
如果当前系统中存在已有LTE的时隙配比，且已有LTE的时隙配比中GP符号数G3配置为4。
903、接入网设备101根据G1和G3确定小区的最大GP符号数G_cell＝max{G1，G3}。
如果当前系统中存在已有LTE的时隙配比，且已有LTE的时隙配比中GP符号数G3配置为4，则接入网设备101为小区配置的实际GP符号数G_cell＝max{G1，G3}＝4符号。
904、接入网设备101根据小区最大GP符号数G_cell，确定上下行时域资源配置信息。
以C-band频段NR系统为例来进行说明，该频段所使用的子载波间隔为30kHz，上下行时隙配比周期5ms，则X＝5ms。接入网设备101根据上下行业务量确定x1＝7，y1＝2。接入网设备101还根据上行物理信道和信号所需要的资源，如SRS或PUCCH，确定上行符号数y2＝4。那么，对应的下行符号数x2＝6。
905、接入网设备101通过小区级RRC信令，向小区内的所有终端设备发送上下行时域资源配置信息。
接入网设备101可以SIB1消息通知小区内的所有终端设备上下行时域资源配置信息，即当前时隙配比信息为：X＝5ms，x1＝7，x2＝6，y1＝2，y2＝4，如图10所示，图10为终端设备当前时隙配比的一个示意图。
906、接入网设备101根据终端设备的上行TA测量结果，确定终端设备所需的最小GP符号数。
接入网设备101对某个终端设备的上行物理信道和信号进行IoT测量，如对PRACH信道和SRS进行IoT测量，根据IoT测量结果更新该终端设备的TA测量值，根据TA测量值和GP符号的对应关系确定终端设备所需要的最小GP符号数G2。
例如：该终端设备如果实际TA测量值为50us，根据上述表3所示，则对应最小GP符号数G2＝2符号。那么终端设备所需要配置的GP符号数为G_UE＝G4＝2，即2符号。
907、接入网设备101根据当前系统上下行物理信道和信号物理资源需求的状况确定增加下行资源。
接入网设备101根据当前系统上下行物理信道和信号物理资源需求的状况，确定增加下行资源。则上行符号数y2固定为4，该终端设备下行实际可用符号数x2_new＝x_add+x2＝4+6＝10。
908、接入网设备101向终端设备发送可用的下行符号数的指示信息。
接入网设备101通过UE级RRC信令或DCI信令，通知终端设备用于上行传输及下行传输的符号数(如x2_new＝10，y2＝4)，从而使得终端设备确定实际使用到的GP符号数和GP位置。
在本申请实施例中，接入网设备101通过测量得到的TA值，确定终端设备实际所需要的GP符号数及可用的下行符号数，通过小区级SIB1信令和UE级RRC信令相结合的方式，实现UE级GP符号数和下行符号数的半静态或动态配置，实现系统资源的有效利用，提升系统性能。在现有技术中，GP符号个数和位置以及上行符号数目是静态配置的。与现有技术相比，在本申请实施例中，近点终端设备下行可用符号数增加，增加了下行PDSCH可用资源，有利于系统性能的提升。
在上述实施例中，GP的配置除了覆盖距离，还需要考虑来自相邻接入网设备或者远端接入网设备的干扰。相邻接入网设备或远端接入网设备的信号需要保证在GP保护范围内，这样相邻接入网设备或者远端接入网设备的下行信号才不会干扰到本接入网设备的上行信号。
此外，当相邻接入网设备或者远端接入网设备的时钟同步出现故障或不可用时，会导致此类接入网设备同步丢失，和周边接入网设备间出现时钟偏差。各个接入网设备的发送、接收时刻不对齐，来自相邻接入网设备或者远端接入网设备的下行信号到达终端设备(user equipment，UE)侧时间点超过GP范围，就会干扰终端设备上行接收，影响系统性能。
在低空大气波导效应下，当远端接入网设备达到一定的高度时，远端接入网设备的大功率下行信号可以产生远距离传输到达近端接入网设备。由于远距离传输时间超过上下行保护间隔，远端接入网设备的下行信号在近端接入网设备的接收时隙被近端接入网设备收到，从而干扰了近端接入网设备的上行信号接收，产生干扰，影响系统性能。
考虑到接入网设备间的干扰场景，造成干扰的原因可能是接入网设备之间的定时偏差，也可能是远端接入网设备的传播干扰。所有接入网设备可以持续监测接收符号上的干扰水平，如果发现接入网设备之间干扰存在，则通过调整信道配置、GP配置，来避让干扰的问题。
本申请提出了一种方案可以针对不同终端设备配置不同的GP长度，例如可以根据干扰检测状况对不同终端设备配置不同的GP长度。利用本申请的方案，可以实现上下行资源的灵活调度，有效规避干扰，最大化可用空口资源，提升系统容量和用户体验。
下面以实施例的方式，对本申请技术方案做进一步的说明，如图11所示，为本申请实施例中上下行资源的干扰协调方法的一个实施例示意图。图11可以与本申请实施例前面提供的时域资源分配方案结合(例如图5A至图10中的方案)或者可以单独进行可以包括：
1101、接入网设备确定终端设备用于上行传输的符号。
这里用于上行传输的符号可以是本申请实施例前面提供的时域资源分配方案中小区所需的GP资源中除了终端设备所需的GP资源以外的上行传输符号，或者小区所需的GP资源以外的上行传输符号。
这里上行传输符号可以是通过小区级半静态配置信息、用户级半静态配置信息或者用户级动态配置信息进行配置的。
1102、接入网设备确定上行干扰符号。
接入网设备根据对上行传输的符号的IoT测量结果，从上行传输的符号中确定上行干扰符号。示例性的，如图12A所示，为本申请实施例中上行干扰符号的示意图。在图12A所示中，以5G 30K子载波典型场景为例，阴影部分表示上行干扰符号，即干扰主要集中在U时隙前部1～2个符号。如图12B所示，为本申请实施例中上行干扰符号的示意图。在图12B所示中，以5G 30K子载波典型场景为例，阴影部分表示上行干扰符号，即干扰主要集中在U时隙尾部的1～4个符号。
1103、接入网设备向终端设备发送信道配置更新消息，信道配置更新消息用于指示终端设备在上行干扰符号上不进行资源调度。
接入网设备确定上行干扰符号数之后，向终端发送信道配置更新消息，该信道配置更新消息用于指示终端设备在上行干扰符号上不进行资源调度。终端设备在除去上行干扰符号的上行传输的符号上进行资源调度。
可以理解的是，在这些上行传输的符号上，可能出现的信道有SRS/PUSCH/PUCCH，接入网设备可以通过UE级RRC信令或DCI信令，指示终端设备调整SRS/PUSCH/PUCCH的信道配置，避开上行干扰符号。
现有技术中，接入网设备无法根据干扰情况灵活避让干扰符号，导致一旦出现干扰，系统业务严重受损。在本申请实施例中，接入网设备确定上行干扰符号后，可以向终端设备发送信道配置更新消息，信道配置更新消息用于指示终端设备在上行干扰符号上不进行资源调度。虽然系统容量稍有损失，但系统业务可正常工作。
如图13所示，图13为本申请实施例中上下行资源的干扰协调方法的一个实施例示意图，可以包括：
1301、第一接入网设备确定第一终端设备用于上行传输的符号。
这里用于上行传输的符号可以是本申请实施例前面提供的时域资源分配方案中小区所需的GP资源中除了终端设备所需的GP资源以外的上行传输符号，或者小区所需的GP资源以外的上行传输符号。
这里上行传输符号可以是通过小区级半静态配置信息、用户级半静态配置信息或者用户级动态配置信息进行配置的。
1302、第一接入网设备确定上行干扰符号和目标接入网设备，目标接入网设备为对上行传输的符号造成干扰的接入网设备。
第一基站根据对上行传输的符号的IoT测量结果，从上行传输的符号中确定上行干扰符号。每个基站都会周期性发送特征序列，第一基站收到其他基站发送的周期性特征序列，第一基站再根据该周期性特征序列，确定目标基站，该目标基站确定的下行符号对该基站的上行符号造成干扰。
1303、第一接入网设备向目标接入网设备发送指示信息。
第一基站向目标基站发送指示信息，该指示信息用于指示目标基站在对该第一基站的上行符号造成干扰的下行符号(下行干扰符号)上不进行资源调度。
示例性的，如图14A所示，为本申请实施例中上行干扰符号的示意图。在图14A所示中，以5G 30K子载波典型场景为例，阴影部分表示上行干扰符号，即干扰主要集中在D时隙前部1～4个符号。此时，第一基站希望目标基站在发送时隙的尾部几个 下行符号上进行避让。
如图14B所示，为本申请实施例中上行干扰符号的示意图。在图14B所示中，以5G 30K子载波典型场景为例，阴影部分表示上行干扰符号，即干扰主要集中在D时隙尾部的1～2个符号。此时第一基站希望目标基站在发送时隙的前部几个下行符号上进行避让。
1304、目标接入网设备向目标终端设备发送信道配置更新消息，信道配置更新消息用于指示终端设备在下行干扰符号上不进行资源调度。
目标基站根据指示信息，确定下行干扰符号，然后，向目标终端设备发送信道配置更新消息，信道配置更新消息用于指示终端设备在下行干扰符号上不进行资源调度。目标终端设备为目标基站覆盖范围内的终端设备。
目标终端设备在下行干扰符号上不进行资源调度的时候，对于基站来说，上行传输的符号都可以进行资源调度，没有上行干扰符号一说了。
在目标基站的下行传输的符号上，可能出现的信道有PDSCH/PUCCH，目标基站修改相关信道配置，并通过UE级RRC信令或DCI信令指示目标UE，避开干扰符号。
现有技术中，基站无法根据干扰情况灵活避让干扰符号，导致一旦出现干扰，系统业务严重受损。在本申请实施例中，基站确定上行干扰符号，进一步还可以确定造成这些上行干扰符号对应的目标基站，向该目标基站发送指示信息，目标基站收到该指示信息后，可以向目标终端设备发送信道配置更新消息，信道配置更新消息用于指示目标终端设备在对基站造成干扰的下行干扰符号上不进行资源调度。对基站来说，系统容量没有损失，系统业务可正常进行工作。对于目标基站来说，系统容量稍有损失，但系统业务可正常工作。
需要说明的是，图11至图14B(包括图11、图12A、图12B、图13、图14A和图14B)中的干扰协调方法同样适用于下行时域资源，当在下行时域资源上受到干扰后，基站可以选择不在该下行时域资源上调度，或者将受到干扰的下行时域资源发送给干扰基站，让干扰基站不进行上行调度。
