Description

一种发送信号的方法及设备
本申请要求在2017年11月27日提交中国专利局、申请号为201711207718.8、发明名称为“一种发送信号的方法及设备”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
本申请涉及通信技术领域，尤其涉及一种发送信号的方法及设备。
背景技术
在无线通信系统中，上行功率控制是无线资源管理的一个非常重要的组成部分，也是影响系统性能和容量的一个非常重要的因素。上行功率控制的主要目的是：补偿信道环境的缓慢变化，减少邻区干扰。
目前，在新通信(new radio，NR)系统中，对于探测参考信号(sounding reference signal，SRS)，可采用开环功率控制，也可采用闭环功率控制。其中，闭环功率控制又可分为累积闭环功率和绝对闭环功率。其中，累积闭环功率是指在当前时隙上发送SRS的功率，是在相邻时隙发送SRS功率的基础上进行累加的，而绝对闭环功率是指在当前时隙上发送SRS的功率，无需在相邻时隙发送SRS功率的基础上进行累加。比如，终端设备周期性在时隙1、时隙3以及时隙5中发送SRS，且采用累积闭环功率控制，那么在时隙3上发送SRS的功率是在时隙1上发送SRS功率的基础上进行累加的，在时隙5中发送SRS的功率是在时隙3上发送SRS功率的基础上进行累加的。需要说明的是，当采用累积闭环功率计算SRS的发送功率时，所述相邻时隙指的发送SRS相邻的时隙，比如，终端设备在时隙1、时隙3以及时隙5上发送SRS，那么时隙1与时隙3称为相邻时隙，时隙3与时隙5称为相邻时隙。
同时，在NR系统中，提出在一个时隙中可同时发送物理上行共享信道(physical uplink shared channel，PUSCH)和SRS，而SRS可被配置为与PUSCH的发射功率参数关联或不关联。在此种场景下，如何确定SRS的发送功率，并没有相关的解决方案。

基于图3、图4或图5所提供的发送信号的方法，本申请提供一种发送信号的方法，该方法中的SRS可具体为图3至图5中的参考信号，时隙(slot)可具体为图3至图5中的第一时间单元、第二时间单元或第三时间单元，具体如下：
设定以下场景，如图6或图7所示，UE周期性在slot#1、slot#6以及slot#11发送SRS，且SRS的发送采用累积闭环功率算法。如果UE在slot6接收到动在slot#6有动态调度的PUSCH传输，那么在时隙#6中会同时传输PUSCH和SRS，且SRS会占用一个slot内最后的N个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号，比如 N可为1、2或4。以下分两种情况进行说明：
第一种情况，UE被配置SRS与PUSCH的发射功率参数关联。在本申请实施例中，在正常累积闭环的处理流程中，slot#6发送SRS的功率，需要在slot#1发送SRS功率的基础上进行累加，slot#11发送SRS的功率，需要在slot#6的基础上进行累加。
由于在本应用场景中，SRS被配置为与PUSCH的发射功率参数关联，因此，在slot#6中，UE会采用PUSCH的发射功率参数，作为SRS在slot#6中发送功率的发射功率参数。因此，slot#11显然不再适用于在slot#6发送功率的基础上进行累加。在本申请实施例中，提供以下方式，确定slot#11中发送SRS的功率：
slot#11中传输的SRS在slot#1中传输SRS的基础上累积功率；
slot#11独立计算传输SRS的闭环功率，比如在slot#11中重置累积闭环功功率或以
绝对功率调整计算。
在本申请实施例中，UE具体采用方式1)或方式2)计算slot#11中传输SRS的功率可通过信令配置，比如，可以通过高层或物理层信令配置，高层信令可以是无线资源控制(radio resource control，RRC)信令或媒体接入控制(media access control，MAC)，物理层信令可以是下行控制信息(down control information，DCI)信令。
第二种情况，UE被配置为SRS与PUSCH发射功率参数不关联。。
在本申请中，为了避免在一个slot内功率的跳变，因此在slot#6中需要保持PUSCH和SRS的发送功率相一致。在一示例中，可在slot#6中，以PUSCH的发送功率，传输PUSCH和SRS，或者，也可以SRS的发送功率，传输PUSCH和SRS，或者，也可以在PUSCH的传输功率和SRS的传输功率中，选择一满足条件(比如传输功率较大或较小)的发送功率，来共同传输PUSCH和SRS，或者，也可对PUSCH的发送功率和SRS的发送功率进行综合(比如求平均)，且将综合后的发送功率作为PUSCH和SRS的发送功率。
此时，Slot#11中发送SRS的功率，可按照以下方式确定：
slot#11中传输的SRS在slot#1中传输SRS的发送功率基础上累积功率；
slot#11独立计算传输SRS的发送功率，比如在slot#11中重置闭环功率
或绝对功率调整计算。
3)slot#11会仍然在slot#6的闭环功率基础上进行累积，但会加上offset值，作为一种可能性，offset值可以通过PUSCH的调度信令DCI携带。
基于图1所示的通信系统100或图2所示的通信系统200，如图8所示，本申请提供一种发送信号的方法，图8中的第一设备可具体为图1中的终端设备102，第二设备可具体为图1中的基站101，或者，图8中的第一设备可具体为图2中的终端设备201，第二设备可具体为图2中的终端设备202，所述方法包括：
步骤S801：第二设备向第一设备发送第一信息。
其中，所述第一信息用于激活参考信号的发送以及指示功率调整值，所述功率调整值用于确定所述参考信号的发送功率。具体的，所述第二设备可向第一设备发送DCI信令，所述DCI信令中可携带所述第一信息。所述参考信号可为SRS，所述SRS包括周期SRS、非周期SRS和半静态SRS中的至少一个。
步骤S802：第一设备根据所述第一信息，向第二设备发送所述参考信号。
在本申请实施例中，当所述参考信号为半静态SRS时，所述功率调整值包括一个调整值，所述一个调整值用于确定在所述半静态SRS的激活期间所有探测参考信号的功率调整值。比如，在半静态SRS的激活期间，UE一共需上报5个SRS，那么5个SRS均照所述第一信息中所指示的一个调整值进行功率调整。再如，所述第一信息中所指示的调整值为1dB，那么在整个半静态SRS的上报期间，5个SRB均按照1dB的功率进行调整。
在本申请实施例中，所述功率调整值也可包括一组调整值，所述一组调整值中包括至少一个调整值，所述一组调整值中的第i个调整值对应于在所述半静态参考信号的激活期间所发送的第i个探测参考信号的功率调整值，所述i为大于零小于等于N的整数，所述N为在所述半静态参考信号的激活期间所发送所述探测参考信号的数量。
比如，仍沿用上述举例，在半静态SRS的激活期间，UE一共需上报5个SRS，那么上述一组调整值中可包括5个调整值，比如分别为1dB、3dB、0dB、1dB以及3dB，那么1dB可对应于半静态SRS的激活期间，第一个SRS的调整值；3dB可对应于半静态SRS的激活期间，第二个SRS的调整值；0dB可对应于半静态SRS的激活期间，第三个SRS的调整值；1dB可对应于半静态SRS的激活期间，第四个SRS的调整值；3dB可对应于半静态SRS的激活期间，第五个SRS的调整值。
由上可见，在本申请实施例中，第二设备通过第一信息，同时激活参考信号的发送和指示功率调整值，从而无需额外信令指示功率调整值，从而减少信令开销。
基于图1所示的通信系统100或图2所示的通信系统200，如图9所示，本申请提供一种发送信号的方法，图9中的第一设备可具体为图1中的终端设备102，第二设备可具体为图1中的基站101，或者，图9中的第一设备可具体为图2中的终端设备201，第二设备可具体为图2中的终端设备202，所述方法包括：
步骤S901：第二设备向第一设备发送第一信息，所述第一信息用于激活参考信号的发送。
在本申请实施例中，所述第一信息可为RRC信令，或MAC信令。
步骤S902：第一设备在第一时间单元，以第一发送功率向第二设备发送所述参考信号。
在本申请实施例中，在所述参考信号被配置为与所述第一信道的发射功率参数关联时，所述第一发送功率为根据在所述第一时间单元上，发送所述第一信道的发送功率所确定；
在所述参考信号被配置为与所述第一信道的发射功率参数不关联时，所述第一发送功率为根据预设调整值所确定的。
在本申请实施例中，所述参考信号可为SRS，所述SRS可包括周期SRS、非周期SRS和半静态SRS中的至少一个，或者，所述参数信息可为SS，所述SS可为PSS或SSS。所述第一信道可为PUSCH、PUCCH或PRACH。由上可见，在本申请实施例中，第一设备可仅发送第一信息用于激活参考信号的发送，而第二设备发送SRS的功率调整值，第二设备可根据自身设置的条件所确定，而无需第一设备进行指示，从而节省信令开销。
基于图1所示的通信系统100或图2所示的通信系统200，如图10所示，本申请提供一种发送信号的方法，图10中的第一设备可具体为图1中的终端设备102，第二设备可具体为图1中的基站101，或者，图10中的第一设备可具体为图2中的终端设备201，第二 设备可具体为图2中的终端设备202，所述方法包括：
步骤S1001：第二设备向第一设备发送第一信息，所述第一信息用于激活参考信号的发送。
步骤S1002：第一设备在第二时间单元，以第二发送功率向所述第二设备发送所述参考信号。
步骤S1003：第一设备在第一时间单元，以第一发送功率向第二设备发送所述参考信号。
在本申请实施例中，在所述参考信号被配置为与所述第一信道的发射功率参数关联时，所述第一发送功率为根据在所述第一时间单元上，发送所述第一信道的功率所确定；
在所述参考信号被配置为与所述第一信道的发射功率参数不关联时，所述第一发送功率根据所述预设调整值所确定，所述第一发送功率为根据预设调整值和所述第二发送功率所确定的。
需要说明的是，本申请实施例中，并不限步骤S1001至步骤1003执行的先后顺序，比如，可在步骤S1001之前，执行步骤S1002。
由上可见，在本申请实施例中，同样无需第一设备指示参考信号上报的调整值，节省信令开销。
基于图9或图10所提供的发送信号的方法，本申请提供一种发送信号的方法，该方法中的SRS可具体为图9或图10中的参考信号，时隙(slot)可具体为图9或图10中的第一时间单元或第二时间单元，该方法主要用于对半静态SRS的处理，具体如下：
基站会向UE发送激活信息，以激活SRS的传输，而UE在接收到所述激活信息后，则开始传输SRS。在本申请实施例中，可通过DCI信令动态激活半静态SRS的上报，也可通过高层信令，例如RRC或MAC信令激活半静态SRS的上报。
第一种情况：若通过DCI激活半静态SRS的上报：
1)如图11所示，可在激活半静态SRS上报的DCI信令中，携带TPC命令，所述TPC命令用于指示在本次激活期间所有SRS的功率调整，即每次发送的SRS会在前一次的基础上加上累积TPC指示的功率调整值。在本申请实施例中，所述激活半静态SRS上报DCI信令可具体为触发半静态SRS的激活(Trigger SP-SRS Activation)，需要说明的是，在本申请实施例中，对于半静态SRS而言，如果需结束SRS的上报，也需基站进行指示，在本申请实施例中，仍可参照11，对于结束半静态SRS上报的信令可称为触发半静态SRS的去激活(Trigger SP-SRS deactivation)
2)如图12所示，同样可在激活半静态SRS上报的DCI信令中，携带TPC命令，所述TPC命令用于指示一组TPC值,对应不同slot传输的SP-SRS的调整值。如图12所示；此时对应的场景可以是，NR中若采用LTE中的树状跳频，可以根据SRS传输的带宽和频域位置来确定携带的一组累积TPC的值，来调整闭环功率。
需要说明的是，在上述方式1)和方式2)中均无需额外的指示信息，用于指示调整值，节省信令开销。同时方式2)可灵活指示SRS的功率调整值。
第二种情况：若通过高层信令(比如，MAC-CE或RRC)触发：
1)若SRS功率被配置为与PUSCH的发射功率参数关联，且在同一slot内有PUSCH传输，则共享PUSCH的发射功率参数和闭环功率控制。
2)若SRS功率与PUSCH发射功率参数不关联或在同一slot内没有PUSCH传输，则预定义默认调整值，例如预定义调整值为0，即闭环功率控制为h(i)＝h(i-1)，直接复用上一次SRS传输的闭环功率，所述i代表传输SRS的时隙号，所述i为大于零小于等于N的整数，所述N代表在半静态SRS激活期间，总共传输SRS的数量。
