Description

确定最大发送功率的方法、 终端及基站 技术领域
本发明涉及无线通信技术领域, 特别涉及一种确定最大发送功率的方法、 终端及基站。 背景技术
在无线通信***中, 用户设备(英文全称: User Equipment , 英文缩写: UE ) 向基站发送上行信号的发送功率越大, 该上行信号传输的距离越远, 相 应的, 该上行信号对该基站的干 4尤也越大。
UE的标称发送功率 Pi由该 UE硬件能力对应的功率等级决定, Pi为该 UE 发送上行信号的能釆用的最大的功率。 为了实现尽量延长上行信号的传输距离 且尽量减少上行信号对基站的干扰, 通常需要进一步将 UE的最大发送功率 Px 限制在 Pi以下。
基站根据 UE的功率等级预先设置限制功率 P2,并将该限制功率 P2发送给 UE。 UE根据该限制功率 P2确定 Px, 其中, Px的上限不超过 P^。P2两者中的 最小值。 比如, 在某通信***中, UE的功率等级为 class 3, 对应的标称发送 功率?1为 23dBm, 基站可以设置限制功率 P2为 20dBm, 并将该限制功率 P2 下发给基站通信范围内的 UE。 UE根据该限制功率 P2确定最大发送功率 P 々 上限和下限, 其中, Px的上限不超过 20dBm。
现有技术中, 基站只能针对具有相同功率等级的多个 UE进行限制功率的 设置, 才能达到预期的效果, 即, 尽量延长上行信号的传输距离且尽量减少上 行信号对基站的干扰。 发明内容

步骤 202, 终端接收基站发送的 N个配置参数, 每个该配置参数用于指示 一种特性信息对应的限制功率。
其中, 该特性信息用于指示功率等级或者业务类型, N不小于 1。
基站预先根据 N个特性信息进行限制功率的设置, 并将设置的 N个限制 功率和对应的特性信息作为配置参数进行广播。
在本实施例中, 基站不仅可以根据终端的功率等级进行限制功率的设置, 还可以根据终端可能使用的业务类型进行限制功率的设置。 比如, 基站可以对 远距离直连通信业务配置较大的限制功率, 为短距离直连通信业务配置较小的 限制功率。
步骤 204, 终端判断该 N个配置参数对应的各个特性信息中是否包含该终 端的特性信息; 若是, 进入步骤 206, 否则, 进入步骤 208。
当基站发送的 N个配置参数对应的各个特性信息中包含该终端的特性信 息时, 进入步骤 206, 根据该终端的特性信息对应的限制功率进行最大发送功 率的配置。当基站发送的 N个配置参数对应的各个特性信息中不包含终端的特 性信息时, 可以进入步骤 208。
步骤 206, 终端根据该终端的特性信息对应的标称发送功率和该终端的特 性信息对应的配置参数所指示的限制功率确定该终端的特性信息对应的最大 发送功率, 该最大发送功率不小于最大发送功率的下限且不大于最大发送功率 的上限。
具体的,所述最大发送功率的下限为 Pi',所述最大发送功率的上限为 Ρ「, 其中,
P i,= min{P2— ΔΤ2, P!-maxCM!+Mj+AT!+ATj , M3)} ;
Pj'= min{P2, PJ ;
其中, Pi为该终端的特性信息对应的标称发送功率, P2为该终端的特性 信息对应的配置参数所指示的限制功率, Mi为该终端的最大回退功率 (英文 全称: Maximum Power Reduction, 英文缩写: MPR ), M2为该终端的附加最 大回退功率 (英文全称: Additional Maximum Power Reduction, 英文缩写: A-MP ), M3为该终端的功率管理最大回退功率(英文全称: Power Management Maximum Power Reduction, 英文缩写: P-MPR ), ΔΤ i为该终端支持跨频带多 载波时, 允许的最大配置的发送功率放松数值(英文全称: Allowed maximum configured output power relaxation due to support for inter-band CA operation ), ΔΤ2为该终端上行信号在载波边缘时, 允许的发送功率放 数值(英文全称: Allowed operating band edge transmission power relaxation )。其中, MPR、 A-MPR 以及 P-MPR是终端在使用不同的带宽, 不同的调制信号 (比如四相相移键控 (英文全称: Quadrature Phase Shift Keying, 英文缩写: QPSK ), 16正交振幅 调制(英文全称: Quadrature Amplitude Modulation,英文缩写: QAM ), 64QAM ), 不同的临道泄露功率比(英文全称: Adjacent Channel Leakage Ratio,英文缩写: ACLR )要求, 不同的带外功率泄露要求, 以及不同的电磁吸收要求情况下的 功率回退。
max ( M!+MJ+AT!+ATJ , M3 )是指取 Μ Μζ+ΔΊ^+ΔΊ^和 Μ3两者之间的 最大值; πώι{Ρ2-ΔΤ2, P!-maxCM!+Mj+AT!+ATj , Μ3)}是指取 Ρ2-ΔΤ2 和 P!-maxCM!+Mj+AT!+ATj , M3) 两者之间的最小值; min{P2, 是指取 P2和 Pi之间的最小值。
该基站发送的 N个配置参数对应的各个特性信息中包含终端的特性信息 时, 该终端可以根据该基站配置的限制功率、 该终端的标称发送功率、 该终端 的回退功率以及该终端的功率放松数值共同确定。
需要说明的是, 当特性信息为功率等级时, 该特性信息对应的标称发送功 率为: 该终端的功率等级对应的标称发送功率; 当特性信息为业务类型时, 该 特性信息对应的标称发送功率为: 该终端使用该业务类型对应业务时的功率等 级对应的标称发送功率。
终端可以有多个功率等级,比如,在某一时间段内,终端的功率等级为 class 1, 在另一段时间段, 终端又可以将功率等级切换为 class 2。 不同的功率等级 对应的标称发送功率各不相同。 当终端的特性信息包括功率等级时, 终端针对 该功率等级确定最大发送功率。
同样的, 终端也可以支持多种不同的业务类型, 与功率等级不同的是, 终 端可以同时进行多种类型的业务。 当终端的特性信息包括业务类型时, 针对该 终端根据使用该业务类型对应业务时的功率等级, 确定该最大发送功率。
步骤 208, 终端根据预设策略确定备选限制功率, 至少根据该备选限制功 率和该终端的特性信息对应的标称发送功率确定该终端的特性信息对应的最 大发送功率。
其中, 当终端对应多个特性信息, 且基站没有为该多个特性信息设置限制 功率时, 终端可以针对该多个特性信息分别确定最大发送功率, 且确定的最大 发送功率对应各自的特性信息使用。
其中, 终端确定备选限制功率的方法可以有如下四种:
1 )终端将该终端的特性信息对应的标称发送功率确定为该备选限制功率。 根据该备选限制功率确定该终端的特性信息对应的最大发送功率时, 确定的该 最大发送功率所在的范围为 [Pi, Pj]; 该最大发送功率的下限为 , 该最大发送 功率的上限为 Pj。
其中, Pf
Figure imgf000013_0001
为该终端的特性信息 对应的标称发送功率, Mi为该终端的最大回退功率, M2为该终端的附加最大 回退功率, M3为该终端的功率管理最大回退功率, 1\为该终端支持跨频带多 载波时, 允许的最大配置的发送功率放 数值, ΔΤ2为该终端上行信号在载波 边缘时, 允许的发送功率放松数值。
在本实施例中, 一种确定备选限制功率的方法是, 将终端的功率等级或者 业务类型对应的标称发送功率确定为该备选限制功率, 即基站不对终端的特性 信息对应的最大发送功率做限制, 终端仅根据其硬件能力或者支持的业务类型 所决定的标称发送功率进行该终端的特性信息对应的最大发送功率范围的设 置。
2 )终端确定该备选限制功率为 0, 并确定该终端的特性信息对应的最大发 送功率为 0。
在本实施例中, 另一种确定备选限制功率的方法是, 将备选限制功率设置 为 0, 即将终端的最大发送功率确定为 0, 也就是当基站没有为终端的特性信 息设置限制功率时, 终端将不向基站发送上行信号。 比如, 若基站未对功率等 级 class 2设置限制功率, 则当终端的功率等级处于 class 2时, 将不向基站发 送上行信号; 或者, 若基站未对端到端 (英文全称: Device to Device, 英文缩 写: D2D )业务设置限制功率, 则当终端进行 D2D 业务时, 将不向基站发送 D2D业务相关的上行信号。
3 )终端将该 N个配置参数对应的各个限制功率中的一个确定为该备选限 制功率。具体的,可以将该 N个配置参数对应的各个限制功率中的最小功率确 定为该备选限制功率。
在本实施例中, 另一种确定备选限制功率的方法是,从基站设置的 N个配 置参数中, 选择一个配置参数, 结合该配置参数对应的限制功率、 终端的特性 信息对应的标称发送功率、终端的回退功率以及终端的功率放 ^数值确定终端 的最大发送功率。 此时, 终端确定特性信息对应的最大发送功率的方式与基站 设置的 N个配置参数对应的各个特性信息中包含该终端的特性信息时确定最 大发送功率范围的方式类似,即确定的该最大发送功率所在的范围为 [ΡΛ Pj"]; 该最大发送功率的下限为 ΡΛ 该最大发送功率的上限为 Pj"。
其中, Pi"= min{P2, — ΔΤ2

Μ3)} ; Ρ,= min{P2,, Ρ!} ; Pi为该终端的特性信息对应的标称发送功率, Ρ2'为确定的备选限制功率, Mi为该终端的最大回退功率, M2为该终端的附加最大回退功率, M3为该终端 的功率管理最大回退功率, ΔΊ^为该终端支持跨频带多载波时, 允许的最大配 置的发送功率放 数值, ΔΤ2为该终端上行信号在载波边缘时, 允许的发送功 率放松数值。
需要说明的是, 为了尽可能的减小终端对基站的影响, 终端可以选择基站 设置的 Ν个限制功率中的最小值来确定自身的最大发送功率。此外,在通常情 况下,基站设置的限制功率的大小与对应的功率等级成正比,即功率等级越高, 对应设置的限制功率越大, 功率等级越低, 对应设置的限制功率越小。 因此, 当特性信息为终端的功率等级时, 还可以选择配置参数中, 最低的功率等级对 应的限制参数。
4 )终端当该特性信息包括功率等级时, 从该 Ν个配置参数对应的各个功 率等级中选择一个指定功率等级; 将该指定功率等级对应的标称发送功率确定 为该备选限制功率。具体的,可以将该 Ν个配置参数对应的各个限制功率中的 最小的功率等级选择为该指定功率等级。 在本实施例中, 另一种确定备选限制功率的方法是, 当终端的特性信息包 括功率等级时,终端从基站为终端配置的 N个配置参数对应的功率等级中,选 择最小的功率等级对应的标称发送功率, 将该最小的功率等级对应的标称发送 功率确定为备选限制功率。 此时, 终端确定特性信息对应的最大发送功率的方 式与上述将该 N个配置参数对应的各个限制功率中的一个确定为该备选限制 功率时确定最大发送功率范围的方式相同, 此处不再赘述。
综上所述, 本发明实施例提供的确定最大发送功率的方法, 通过接收基站 发送的 N个配置参数, 若该 N个配置参数对应的各个特性信息中包含该终端 的特性信息, 则根据该终端的特性信息对应的限制功率设置最大发送功率, 可 以实现基站在针对具有不同功率等级或者业务类型的多个 UE进行限制功率的 设置时, 依然达到预期的效果, 即, 尽量延长上行信号的传输距离且尽量减少 上行信号对基站的干扰。
同时, 本发明实施例提供的确定最大发送功率的方法, 特性信息中还可以 包含业务类型, 不仅可以通过终端的功率等级设置最大发送功率, 还可以通过 业务类型进行设置。

同时, 本发明实施例提供的确定最大发送功率的方法, 特性信息中还可以 包含业务类型, 不仅可以通过终端的功率等级设置最大发送功率, 还可以通过 业务类型进行设置。 请参考图 4, 其示出了本发明一个实施例提供的确定最大发送功率的方法 的方法流程图, 该方法可以用于在由基站和终端组成的***中, 对终端的最大 发送功率进行设置。 该方法可以包括:
步骤 402, 基站确定 N个配置参数, 每个配置参数用于指示一种特性信息 对应的限制功率。
其中, 该特性信息用于指示功率等级或者业务类型, N不小于 1。
基站预先根据至少一个特性信息进行限制功率的设置, 并将设置的限制功 率和对应的特性信息作为配置参数。
为了进一步提高终端的最大发送功率的设置效果, 在本实施例中, 基站不 仅可以根据终端的功率等级进行限制功率的设置,还可以根据终端可能使用的 业务类型进行限制功率的设置。 比如, 基站可以对远距离直连通信业务配置较 大的限制功率, 为短距离直连通信业务配置较小的限制功率。
步骤 404, 基站将该 N个配置参数发送给终端。
基站可以通过广播的形式将配置参数发送给覆盖范围内的所有终端。 步骤 406, 终端判断该 N个配置参数对应的各个特性信息中是否包含该终 端的特性信息; 若是, 进入步骤 408, 否则, 进入步骤 410。

Pj'= min{P2, PJ ;
其中, Pi为该终端的特性信息对应的标称发送功率, P2为该终端的特性 信息对应的配置参数所指示的限制功率, Mi为该终端的最大回退功率, M2为 该终端的附加最大回退功率, M3为该终端的功率管理最大回退功率, 为该 终端支持跨频带多载波时, 允许的最大配置的发送功率放 数值, ΔΤ2为该终 端上行信号在载波边缘时, 允许的发送功率放松数值。 其中, MPR、 A-MPR 以及 P-MPR是终端在使用不同的带宽, 不同的调制信号, 不同的临道泄露功 率比要求, 不同的带外功率泄露要求, 以及不同的电磁吸收要求情况下的功率 回退。
max ( M!+MJ+AT!+ATJ, M3 )是指取 Μ Μζ+ΔΊ^+ΔΊ^和 Μ3两者之间的 最大值; min{P2-AT2, P!-maxCM!+Mj+AT!+ATj , Μ3)}是指取 Ρ2-ΔΤ2 和 P!-maxCM!+Mj+AT!+ATj , M3) 两者之间的最小值; min{P2, 是指取 P2和 Pi之间的最小值。
基站发送的 N个配置参数对应的各个特性信息中包含终端的特性信息时, 终端可以根据基站配置的限制功率、 终端的特性信息对应的标称发送功率、 终 需要说明的是, 当特性信息为功率等级时, 该特性信息对应的标称发送功 率为: 该终端的功率等级对应的标称发送功率; 当特性信息为业务类型时, 该 特性信息对应的标称发送功率为: 该终端使用该业务类型对应业务时的功率等 级对应的标称发送功率。
终端可以有多个功率等级,比如,在某一时间段内,终端的功率等级为 class 1, 在另一段时间段, 终端又可以将功率等级切换为 class 2。 不同的功率等级 对应的标称发送功率各不相同。 当终端的特性信息包括功率等级时, 终端针对 该功率等级确定最大发送功率。
同样的, 终端也可以支持多种不同的业务类型, 与功率等级不同的是, 终 端可以同时进行多种类型的业务。 当终端的特性信息包括业务类型时, 针对该 终端根据使用该业务类型对应业务时的功率等级, 确定该最大发送功率。
步骤 410, 终端根据预设策略确定备选限制功率, 至少根据该备选限制功 率和该终端的特性信息对应的标称发送功率确定该终端的特性信息对应的最 大发送功率。
其中, 当终端对应多个特性信息, 且基站没有为该多个特性信息设置限制 功率时, 终端可以针对该多个特性信息分别确定最大发送功率, 且确定的最大 发送功率对应各自的特性信息使用。
其中, 终端确定备选限制功率的方法可以有如下四种:
1 )终端将该终端的特性信息对应的标称发送功率确定为该备选限制功率。 根据该备选限制功率确定该终端的特性信息对应的最大发送功率时, 确定该终 端的特性信息对应的最大发送功率所在的范围为 [Pi, Pj]; 该最大发送功率的下 限为 , 该最大发送功率的上限为 Pj。
其中, Pf
Figure imgf000018_0001
Pi为该终端的特性信息 对应的标称发送功率, Mi为该终端的最大回退功率, M2为该终端的附加最大 回退功率, M3为该终端的功率管理最大回退功率, 1\为该终端支持跨频带多 载波时, 允许的最大配置的发送功率放 数值, ΔΤ2为该终端上行信号在载波 边缘时, 允许的发送功率放松数值。
在本实施例中, 一种确定备选限制功率的方法是, 将终端的功率等级或者 业务类型对应的标称发送功率确定为该备选限制功率, 即基站不对终端的特性 信息对应的最大发送功率做限制, 终端仅根据其硬件能力或者支持的业务类型 所决定的标称发送功率进行该终端的特性信息对应的最大发送功率范围的设 置。
2 )终端确定该备选限制功率为 0, 并确定该终端的特性信息对应的最大发 送功率为 0。
在本实施例中, 另一种确定备选限制功率的方法是, 将备选限制功率设置 为 0, 即将终端的最大发送功率确定为 0, 也就是当基站没有为终端的特性信 息设置限制功率时, 终端将不向基站发送上行信号。 比如, 若基站未对功率等 级 class 2设置限制功率, 则当终端的功率等级处于 class 2时, 将不向基站发 送上行信号; 或者, 若基站未对端到端业务设置限制功率, 则当终端进行 D2D 业务时, 将不向基站发送 D2D业务相关的上行信号。
3 )终端将该 N个配置参数对应的各个限制功率中确定一个为该备选限制 功率。具体的, 可以将该 N个配置参数对应的各个限制功率中的最小功率确定 为该备选限制功率。
在本实施例中, 另一种确定备选限制功率的方法是,从基站设置的 N个配 置参数中, 选择一个配置参数, 结合该配置参数对应的限制功率、 终端的特性 信息对应的标称发送功率、终端的回退功率以及终端的功率放 ^数值确定终端 的最大发送功率。 此时, 终端确定特性信息对应的最大发送功率的方式与基站 设置的 N个配置参数对应的各个特性信息中包含该终端的特性信息时确定最 大发送功率范围的方式类似, 即确定该终端的特性信息对应的最大发送功率所 在的范围为 [Pi", Pj"]; 该最大发送功率的下限为 ΡΓ, 该最大发送功率的上限 为 ΡΛ
其中, Pi"= min{P2, — ΔΤ2
Figure imgf000019_0001
Μ3)} ; Ρ,= min{P2,, Ρ^ ; Pi为该终端的特性信息对应的标称发送功率, Ρ2'为确定的备选限制功率, Mi为该终端的最大回退功率, M2为该终端的附加最大回退功率, M3为该终端 的功率管理最大回退功率, ΔΊ^为该终端支持跨频带多载波时, 允许的最大配 置的发送功率放 数值, ΔΤ2为该终端上行信号在载波边缘时, 允许的发送功 率放松数值。
需要说明的是, 为了尽可能的减小终端对基站的影响, 终端可以选择基站 设置的 Ν个限制功率中的最小值来确定自身的最大发送功率。此外,在通常情 况下,基站设置的限制功率的大小与对应的功率等级成正比,即功率等级越高, 对应设置的限制功率越大, 功率等级越低, 对应设置的限制功率越小。 因此, 当特性信息为终端的功率等级时, 还可以选择配置参数中, 最低的功率等级对 应的限制参数。
4 )终端当该特性信息包括功率等级时, 从该 Ν个配置参数对应的各个功 率等级中选择一个指定功率等级; 将该指定功率等级对应的标称发送功率确定 为该备选限制功率。具体的,可以将该 Ν个配置参数对应的各个限制功率中的 最小的功率等级选择为该指定功率等级。
在本实施例中, 另一种确定备选限制功率的方法是, 当终端的特性信息包 括功率等级时,从基站为终端配置的 Ν个配置参数对应的功率等级中,选择最 小的功率等级对应的标称发送功率,将该最小的功率等级对应的标称发送功率 确定为备选限制功率。 此时, 终端确定特性信息对应的最大发送功率的方式与 上述将该 N个配置参数对应的各个限制功率中的一个确定为该备选限制功率 时确定最大发送功率范围的方式相同, 此处不再赘述。
综上所述, 本发明实施例提供的确定最大发送功率的方法, 通过接收基站 发送的 N个配置参数, 若该 N个配置参数对应的各个特性信息中包含该终端 的特性信息, 则根据该终端的特性信息对应的限制功率设置最大发送功率, 可 以实现基站在针对具有不同功率等级或者业务类型的多个 UE进行限制功率的 设置时,依然达到预期的效果,即,尽量延长上行信号的传输距离且尽量减少上 行信号对基站的干扰。
