For example, the PRS in the figure repeats 4 times in each cycle, and the muting pattern is [1010], then the first and third repetition positions in each cycle will be sent.

具体实施方式
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实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
下面对本申请实施例涉及的术语进行简要说明，如下所示：
1：新无线(NR，New Radio)中的定位参考信号(PRS，Positioning Reference Signal)配置
为了减小不同小区之间的干扰，NR设计PRS时引入了静音机制(muting pattern)，基站发送PRS时，不会传输muting pattern中为0的对应PRS，只传输muting pattern中为1的对应PRS。具体可分为以下两种：
静音方案1(MutingOption1)：是按照周期级别的PRS occasion来进行静音，可能会改变PRS实际传输的周期。例如图1A中PRS周期为20ms，muting pattern是[1010]，那么实际传输的周期是40ms。可选地，还可以配置dl-PRS-MutingBitRepetitionFactor(PRS静音比特重复因子)参数，用于指示按照几个PRS周期为一组来做静音。如图1B所示，是现有技术中PRS静音机制1中的dl-PRS-MutingBitRepetitionFactor的一个示意图。其中，dl-PRS-MutingBitRepetitionFactor＝2，则每两个周期的PRS会作为一组，对应muting pattern中的一比特信息。
静音方案2(MutingOption2)：是按照周期内PRS重复实例级别来进行静音。会影响每个周期内的PRS重复次数，但并不会影响PRS实际的发送周期。例如图中PRS在每个周期内重复4次，muting pattern是[1010]，那么每个周期内的第一和第三个重复位置才会发送。
协议38.211中PRS在时隙(slot)中的映射方式可以体现出以上两种静音机制。本申请技术方案主要考虑如何根据muting pattern option 1来确定PRS周期的放大因子。
如图1A所示，是两种PRS静音机制的一个示意图。
在图1A所示中，PRS传输的静音机制：
目的是使PRS机会静音，以便UE能够听到同一资源上的另一个PRS。支持两种静音方法：周期级别和重复级别。
静音方法1：周期级别。一个L比特位图指示哪个周期中的所有PRS集合应该被静音。L＝2/4/8/16/32。比特＝0表示静音。
静音方法2：重复级别。一个T比特位图指示所有PRS集合的哪些重复实例被静音。L＝2/4/8/16/32。比特＝0表示静音。

2：PRS测量周期
RAN 4在讨论PRS测量周期时，需要根据PRS的传输周期和测量间隔重复周期(Measurement Gap Repetition Period，MGRP)等确定一个基础的PRS采样周期。考虑到静音机制1可能会改变PRS传输的实际周期，在RAN4#98bis-e会议讨论中，达成如下结论。需要对PRS周期(高层配置的周期)进行N_muting倍的放大。但为了避免过度放大，对N_muting取值设置了上限，并给出了两种备选方案。
对于Tprs*dl-PRS-MutingBitRepetitionFactor-r16>10240ms的情况，经分析可以通过限制高层PRS配置来实现，比如长期演进(Long Term Evolution，LTE)的PRS有如下限制。
当UE接收到T REP-bit静音机制以及PRS周期T PRS时，对于超过10240子帧的相同小区(例如T REP×T PRS>10240子帧)，UE应基于前n比特假设n比特静音机制，其中n＝10240/T PRS。也可以写成n＝floor[10240/Tprs]。
When the UE receives a T REP-bit muting pattern together with a PRS periodicity T PRS for the same cell which exceeds 10240 subframes(i.e.,T REP×T PRS>10240 subframes),the UE shall assume an n-bit muting pattern based on the first n-bits,where n＝10240/T PRS.
LTE在定义PRS测量周期时并未考虑根据muting pattern对PRS信号的周期进行放大。 但NR如果不考虑静音机制会大大限制测量周期指标的应用场景。
相关协议如下所示：
如果应用静音方案1，则PRS资源的周期性将按N_muting倍进行放大
·N_muting＝X*dl-prs-MutingBitRepetitionFactor；
·X是mutingOption1-r16的NR-MutingPattern-r16的大小。
·N_muting上限值为FFS
o方案A：
如果Tprs*dl-PRS-MUTINGBITTREPECTIONFACTOR-r16>10240ms
·N_muting＝1(实际上没有类型1静音，网络应避免的拐角情况)
其他
·N_muting＝X*dl-PRS-mutingbitrepeationfactor-r16，其中
·X＝min(L，10240/(Tprs*dl-PRS-MutingBitRepeationFactor-r16))，以及
·对于mutingOption1-r16，L是NR-MutingPattern-r16的大小。
o选项B：
·如果Tprs*dl-PRS-MUTINGBITTREPECTIONFACTOR-r16>10240ms
N_muting＝1
·其他
o N_muting＝min{1，[X]}，[X＝2]
·其他
o N_muting＝min{L，[Y]}，[Y＝8]
o不排除其他选择。
对应英文翻译如下：
Agreements:
If muting option 1 is applied,the periodicity of a PRS resource is scaled by N_muting
N_muting＝X*dl-prs-MutingBitRepetitionFactor
X is the size of NR-MutingPattern-r16 for mutingOption1-r16.
N_muting upper bound value is FFS
Option A:
If Tprs*dl-PRS-MutingBitRepetitionFactor-r16>10240ms
N_muting＝1(effectively no type1 muting,corner case that should be avoided by the network)
else
N_muting＝X*dl-PRS-MutingBitRepetitionFactor-r16,where
X＝min(L,10240/(Tprs*dl-PRS-MutingBitRepetitionFactor-r16))and
L is the size of NR-MutingPattern-r16 for mutingOption1-r16.
Option B:
If Tprs*dl-PRS-MutingBitRepetitionFactor-r16>10240ms
N_muting＝1
Elseif L∈{2,4}
N_muting＝min{L,[X]},[X＝2]
Elseif L∈{6,8,16,32}
N_muting＝min{L,[Y]},[Y＝8]
Other options are not precluded。
NR为了减小不同小区之间的干扰，对PRS采用静音机制，其中静音机制1会改变实际的PRS传输周期。而RAN4在计算PRS周期时需要根据实际的PRS传输周期来确定总的测量周期。因此如何根据muting pattern来计算PRS实际传输周期是一个亟待解决的问题。
如上述技术所述，在确定PRS测量周期时需要根据muting pattern(静音机制1)对PRS周期进行放大。目前的备选方案中，option A主要是为了避免PRS周期放大之后超过10240ms的SFN周期的情况，与LTE中的限制比较类似。Option B在此基础上，对不同长度的muting pattern进一步限制了放大因子的上限。但是却没有考虑muting pattern中具体的配置而直接设置上限是不合理的。如当muting pattern＝[1000]或[0010]时，按照option B的方案只能放大2倍是不足的；但实际应该放大4倍。

可选的，当PRS周期大于或等于测量间隔重复周期(Measurement Gap Repetition Period，MGRP)时，根据定位参考信号PRS静音机制所包含比特值为1的比特，确定PRS周期放大因子。当PRS周期大于或等于MGRP时，即每个周期的PRS传输位置都在MG内时，本申请实施例能够较好地工作。
可选地，所述MGRP为最大的MGRP，或者，终端设备所配置的MGRP。示例性的，当PRS周期大于或等于最大的MGRP周期(例如160ms)；或者，当PRS周期大于或等于该UE所配置的MGRP(例如可能的取值是20ms、40ms、80ms、160ms)。
场景1：可选的，在
Figure PCTCN2021092867-appb-000036
的情况下，L’＝L，N’＝N，其中，Tprs是高层配置的PRS周期。
(1)可选的，
Figure PCTCN2021092867-appb-000037
或，X＝ceil[L’/N’]，ceil表示向上取整。
(2)可选的，X取值为L’/N’向上取最小的L’的因数。示例性的，如果L’＝8，N’＝3，L’/N’＝2.67，而8的因数为{8，4，2，1}，向上取比2.67大的最小的因数则为4。因此最终放大倍数X＝4。
(3)可选的，当所述PRS静音机制的当前长度L’为2的幂次时，
Figure PCTCN2021092867-appb-000038
或，X＝2^(ceil[log2(L’/N’)])，ceil表示向上取整。示例性的，当muting pattern的当前长度L’为2的幂次时，如8/16/32等，向上最小因数的方法可等价替换为：X＝2^(ceil[log2(L’/N’)])。
示例性的，如果
Figure PCTCN2021092867-appb-000039
即PRS信号静音(muting)之后的周期不超 过10240ms，说明muting pattern的所有比特位都是有效的。其中，Tprs是高层信号配置的PRS周期，L是muting pattern option 1的原始长度。
假设muting Pattern＝[a 0a 1a 2...a L-1]，其原始长度为L，其中比特值为1的比特个数为N，N≤L。则放大倍数为N_muting，其中，
Figure PCTCN2021092867-appb-000040
Figure PCTCN2021092867-appb-000041
或者，N_muting＝X，而X＝ceil[L’/N’]。
在上述场景1中，因为
Figure PCTCN2021092867-appb-000042
说明muting pattern的所有比特位都是有效的。所以，存在L’＝L，N’＝N；那么，可以根据muting pattern的原始长度L和原始长度L中所包含比特值为1的比特个数N，来确定PRS周期放大因子，也可以称为PRS周期放大倍数。所以，X＝ceil[L’/N’]＝ceil[L/N]。
Muting pattern原始长度为2比特时，N的取值为1，2；那么X的值可能是ceil[2/1]＝2，ceil[2/2]＝1；
Muting pattern原始长度为4比特时，N的取值为1，2，3，4；那么X的值可能是ceil[4/1]＝4，ceil[4/2]＝2，ceil[4/3]＝2，ceil[4/4]＝1；
Muting pattern原始长度为6比特时，N的取值为1，2，3，4，5，6；那么X的值可能是ceil[6/1]＝6，ceil[6/2]＝3，ceil[6/3]＝2，ceil[6/4]＝2，ceil[6/5]＝2，ceil[6/6]＝1；
Muting pattern原始长度为8比特时，N的取值为1，2，3，4，5，6，7，8；那么X的值可能是ceil[8/1]＝8，ceil[8/2]＝4，ceil[8/3]＝3，ceil[8/4]＝2，ceil[8/5]＝2，ceil[8/6]＝2，ceil[8/7]＝2，ceil[8/8]＝1。这时出现了3这个值，不能被8整除，8比特muting pattern按照3个为一组会多出2比特。
Muting pattern原始长度为16比特时，N的取值为1，2，3，4，5，6，7，8，9，10，11，12，13，14，15，16；那么X的取值可能是ceil[16/1]＝16，ceil[16/2]＝8，ceil[16/3]＝6，ceil[16/4]＝4，ceil[16/5]＝4，ceil[16/6]＝3，ceil[16/7]＝3，ceil[16/8]＝2，ceil[16/9]＝2，...，ceil[16/16]＝1。
Muting pattern原始长度为32比特时，N的取值为1，2，3，4，5，6，7，8，9，10，11，12，13，14，15，16，17，18，19，20，21，22，23，24，25，26，27，28，29，30，31，32；那么X的取值可能是ceil[32/1]＝32，ceil[32/2]＝16，ceil[32/3]＝11，ceil[32/4]＝8，ceil[32/5]＝7，ceil[32/6]＝6，ceil[32/7]＝6，ceil[32/8]＝4，ceil[32/9]＝4，ceil[32/10]＝4，ceil[32/11]＝3，ceil[32/12]＝3，ceil[32/13]＝3，ceil[32/14]＝3，ceil[32/15]＝3，ceil[32/16]＝2，ceil[32/17]＝2，ceil[32/18]＝2，...，ceil[32/32]＝1。
以此类推其他原始长度muting pattern的PRS周期放大因子，此处不再一一赘述。
场景2：可选的，在
Figure PCTCN2021092867-appb-000043
的情况下，L’＜L，N’＜N；其中，Tprs是高层配置的PRS周期，L’为L中前L’个比特位的长度，N’为所述前L’个比特位中比特值为1的个数。
(1)可选的，
Figure PCTCN2021092867-appb-000044
或，X＝ceil[L’/N’]，ceil表示向上取整。
(2)可选的，X取值为L’/N’向上取最小的L’的因数。示例性的，如果L’＝8，N＝3，L’/N’＝2.67，而8的因数为{8，4，2，1}，向上取比2.67大的最小的因数则为4。因此最终放大倍数X＝4。
(3)可选的，当所述PRS静音机制的当前长度L’为2的幂次时，
Figure PCTCN2021092867-appb-000045
或，X＝2^(ceil[log2(L’/N’)])，ceil表示向上取整。示例性的，当muting pattern的当前长度L’为2的幂次时，如8/16/32等，向上最小因数的方法可等价替换为： X＝2^(ceil[log2(L’/N’)])。
示例性的，如果
Figure PCTCN2021092867-appb-000046
且
Figure PCTCN2021092867-appb-000047
或，
Figure PCTCN2021092867-appb-000048
每个PRS组的长度没有超过10240ms，但是与muting pattern的原始长度L相乘后超过10240ms，这意味着muting pattern中只有前L’个比特位是有效的。其中，Tprs是高层信号配置的PRS周期，L是muting pattern option 1的原始长度。
假设muting Pattern＝[a 0a 1a 2...a L-1]，其原始长度为L，其中比特值为1的比特个数为N，N≤L。则放大倍数为N_muting，其中，
Figure PCTCN2021092867-appb-000049
或者，N_muting＝X，而X＝ceil[L’/N’]，L’为muting pattern L中前L’个有效比特位的长度，N’是muting pattern的前L’个比特位中比特值为1的个数。
在上述场景2中，因为
Figure PCTCN2021092867-appb-000050
所以，存在L’＜L，N’＜N；长度L’为muting pattern原始长度L截断后的前L’比特位的长度，N’为长度L’中比特值为1的个数。那么，根据muting pattern的原始长度L和所包含比特值为1的比特个数N，来确定PRS周期放大因子，也可以称为PRS周期放大倍数。所以，X＝ceil[L’/N’]。
需要说明的是，在场景3中，如果
Figure PCTCN2021092867-appb-000051
N_muting＝1。由于每个PRS组的长度就已经超过了10240ms，相当于muting pattern没有实际作用。因此周期不需要放大。与现有技术方案中的两个方案相同，此处不再赘述。
实现方式2、终端设备根据定位参考信号PRS静音机制的长度和所包含比特值为1的位置，确定PRS周期放大因子。
可选的，所述根据定位参考信号PRS静音机制的长度和所包含比特值为1的位置，确定PRS周期放大因子，可以包括：根据所述PRS静音机制的长度，确定所述长度的因数；根据所述因数和所述比特值为1的位置，确定PRS周期放大因子。

可选的，所述目标因数按照所述因数从小到大排列的顺序选择。
可选的，所述判断是否存在相隔目标因数比特位的比特值都为1，若存在则所述PRS周期放大因子为所述目标因数，所述因数包括所述目标因数，可以包括：判断是否存在每相隔目标因数比特位的比特值都为1，若存在则所述PRS周期放大因子为所述目标因数。
可选的，所述因数的取值不为1。
示例性的，可以根据muting pattern的比特值为1所处的位置来确定PRS周期放大因子。假设muting Pattern＝[a 0a 1a 2...a L-1]，其长度为L，且L有非1的因数X1，X2，…XN，X1＜X2＜…XN-1＜XL按从小到大排列依次进行下述判断。
如果Xi<L，Mi*Xi＝L。取出mutingPattern中长度为Mi的部分比特，称为子位图，sub_pattern(s)＝[a sa s+Xia s+2*Xi...a s+(Mi-1)Xi]。其中s为起始位置，取值范围是[0，Xi-1]，一共可以生成Xi个子位图。
只要有一个s取值下对应的Mi个比特全部为1，则最终的X＝Xi；
否则换下一个Xi+1，重复上述步骤；
如果Xi＝L，则X＝L。
(1)以L＝8为例，按照下述顺序进行判断mutingPattern＝[a 0a 1a 2a 3a 4a 5a 6a 7]，X＝{1，2,4,8}。
如果a1a2a3a4a5a6a7全为1，就放大1倍；
如果a0a2a4a6＝1111，或者，a1a3a5a7＝1111，就放大2倍；
如果a0a4＝11，或，a1a5＝11，或，a2a6＝11，或，a3a7＝11，就放大4倍；
其他的放大8倍；
(2)以L＝16为例，按照下述顺序进行判断mutingPattern＝[a 0a 1a 2...a 13a 14a 15],X＝{1，2,4,8,16}。
如果mutingPattern全为1，就放大1倍；
如果a0a2a4a6a8a10a12a14＝11111111，或者，a1a3a5a7a9a11a13a15＝11111111，就放大2倍；
如果a0a4a8a12＝1111，或，a1a5a9a13＝1111，或，a2a6a10a14＝1111，或，a3a7a11a15＝1111，就放大4倍；
如果a0a8＝11，或，a1a9＝11，或，a2a10＝11，或，a3a11＝11，或，a4a12＝11，或，a5a13＝11，或，a6a14＝11，或，a7a15＝11，就放大8倍；
其他的放大16倍；
可类推到其他muting pattern的情况，此处不再一一赘述。
