LTE R8上行设计保证了严格的单载波特性,即对于一个 UE( User Equipment, 终端) 来说, 每一时刻在上行只发送一种物理信道或信 号。 因此, 当一个 UE在上行子帧中被调度了 PUSCH发送, 同时又 要在该子帧发送 PUCCH信道时,为了保证 UCI传输的实时性同时维 持单载波特性, 需要将 UCI插入到上行数据包中, 在 PUSCH发送, 如图 2所示的第 2个子帧。 在 LTE R8中, PUSCH和 PUCCH的功率 采用各自独立的闭环操作进行控制, 由于在一个上行子帧中 UE只可 能发送 PUSCH和 PUCCH其中一种信道, 因此每个子帧的发射功率 受 PUSCH或 PUCCH闭环功率控制命令字进行控制。 LTE R8中定义 了上行功率裕量报告(PHR, Power Headroom Report ), UE计算当前 子帧的发射功率裕量上报给网络侧设备,网络侧设备利用该值决定下 一次上行数据调度的 MCS ( Modulation and Coding Scheme, 调制编 码方案)和资源分配, 以避免 UE出现发射功率受限。 PHR定义为子 帧 i中 PUSCH的发射功率和 UE最大发射功率之间的差值:
PH (i) = PCMAX - PPUSCH (i) ( 1 )

网络侧设备包括小区、 Node B、 eNB以及其他实体,但不限于此, 凡是能够起到网络侧作用的设备均属于本发明的保护范围。本发明实 施例中以网络侧设备为基站为例进行说明。
本发明的一个实施例提供了一种上行信道配置方法, 如图 4 所 示, 具体包括以下步骤:
步骤 401、 基站配置 UE的上行传输模式。
步骤 402、 当上行传输模式与 UE的当前传输模式不同时, 基站 将携带上行传输模式的消息发送给 UE, 使 UE使用上行传输模式进 行上行传输以及根据上行传输模式获取信道质量信息并上报给基站。
步骤 403、 基站接收 UE上报的信道质量信息。
步骤 404、 基站根据信道质量信息配置上行信道。
本发明的另一实施例提供了一种上行信道配置方法, 如图 5 所 示, 具体包括以下步骤:
步骤 501、 基站根据信道质量信息配置上行信道, 其中包括配置 上行传输模式。
上行传输模式包括以下两种:
上行传输模式 1: UE的上行传输具有单载波特性。
UE 上行传输的一个子帧内只能在 PUSCH 上进行数据传输或 PUCCH 上进行数据传输。 当两者同时需要进行数据传输时, 将在 PUCCH进行传输的 UCI插入到 PUSCH中进行传输。
上行传输模式 2: UE的上行传输具有多载波特性。
UE的上行传输的一个子帧内可以同时在 PUSCH和 PUCCH上进 行数据传输。 当然, 也可以通过两者之一进行数据传输。
由于终端采用上行传输模式 1 所需要的功率小于终端采用上行 传输模式 2所需要的功率,优选地,基站为终端配置上行传输模式 1 , 此时基站对 PUSCH和 PUCCH独立进行闭环功率控制。
步骤 502、 基站通过信令通知 UE为其配置的上行传输模式。 优选的, 基站通过高层信令 RRC信令或 MAC信令通知 UE。 步骤 503、 UE接收基站配置的上行传输模式, 并使用该上行传 输模式进行上行传输。
步骤 504、 UE根据上行传输模式计算发射功率裕量 PHR。
当 UE采用上行传输模式 1进行上行传输时, 基站对 PUSCH和
PUCCH独立进行闭环功率控制, PHR的计算公式为:
PH (i)― PCMAX - PPUSCH (i) (2) 其中, PCMAX为 UE的最大允许发射功率, PPUSCH(i)为子帧 i 中 PUSCH的发射功率, PH(i)为发射功率裕量, 为 PCMAX与 PPUSCH(i)的 差值, 即为 UE上报给基站的 PHR。
当 UE采用上行传输模式 2进行上行传输时, 基站对 PUSCH和 PUCCH独立进行闭环功率控制, PHR的计算公式为:
PH (i)― PCMAX ~~ PPUSCH (i) _ Ppuccn (i) (3) 其中, PCMAX为 UE的最大允许发射功率, PPUSCH(i)为子帧 i 中 PUSCH的发射功率, PPUCCH(i)为子帧 i中 PUCCH的发射功率, PH(i) 为发射功率裕量, 为 PCMAX与 PPUSCH(i)和 PPUCCH(i)的差值, 即为 UE 上报给基站的 PHR。 此时, 当 UE的上行子帧中仅在 PUSCH进行传 输时, 公式 3中 PPUCCH(i)为零。
步骤 505、 UE将 PHR发送给基站。
步骤 506、 基站接收 UE上报的 PHR, 根据该 PHR进行上行信 道配置, 其中包括根据 PHR重新配置上行传输模式。
基站根据该 PHR进行上行信道配置为:由于上行 MCS等级越高, 分配的物理资源越多, 所需要的终端发射功率越大。 所以基站利用 UE上报的 PHR决定下一次上行数据调度的 MCS和资源分配, 以避 免 UE出现发射功率受限问题。 基站根据 PHR重新配置上行传输模式有两种方式, 方式 1为基 站设置一个 PHR 阈值 PHR_thr, 根据 UE上报的 PHR 与该阈值 PHR_thr的关系配置上行传输模式; 方式 2为基站设置两个 PHR阈 值 PHR_thrl和 PHR_thr2, 其中 PHR_thrl<PHR_thr2, 根据 UE上报 的 PHR与 PHR_thrl或 PHR_thr2的关系配置上行传输模式。
本发明实施例中以基站采用方式 1根据 PHR重新配置上行传输 模式为例进行说明。
具体的, 基站采用方式 1根据 PHR重新配置上行传输模式具体 包括以下步骤:
( 1 )基站设置 PHR阈值 PHR_thr, 该 PHR_thr的设置可根据仿 真结果或实际测试而得。
( 2 )基站根据 UE上报的 PHR与该阈值 PHR_thr的关系配置上 行传输模式。
当 UE上报的 PHR >阈值 PHR_thr时,基站为终端配置上行传输 模式 2;
当 UE上报的 PHR <阈值 PHR_thr时,基站为终端配置上行传输 模式 1。
上述判断方式表明, 当 UE上报的 PHR大于阈值 PHR_thr, 则说 明 PUSCH的发射功率较小, PHR较大, 所以基站为终端配置上行传 输模式 2; 当 UE上报的 PHR小于阈值 PHR_thr, 则说明 PUSCH的 发射功率较大, PHR较大, 所以基站为终端配置上行传输模式 1。
其中, UE上报的 PHR可以是某一子帧 i的瞬时 PHR, 也可以是 对一段时间的 PHR上报进行平滑后的结果。
步骤 507、 基站判断为终端重新配置的上行传输模式是否与 UE 当前的传输模式相同。
当判断结果为相同时,基站不将所配置的上行传输模式通过信令 通知 UE, 转到步骤 506。
当判断结果为不同时,基站将所配置的上行传输模式通过信令通 知 UE, UE切换至基站配置的该传输模式, 转到步骤 502。 上述上行传输模式的配置与 PHR的计算二个过程是相辅相成的 关系, 当基站配置了上行传输模式, 则 UE根据该上行传输模式计算 PHR; 当 UE计算完 PHR, 基站根据获取的 PHR配置传输模式。 当 UE第一次接入时, 基站为 UE配置上行传输模式, 优选地, 基站为 UE配置上行传输模式 1。
本发明实施例中以基站根据发射功率裕量配置上行传输模式,但 并不限于此,凡是可以表征信道质量好坏的信道质量参数均可以用来 配置上行传输模式。 此外,基站根据信道质量参数不仅可以配置上行 传输模式, 还可以进行其他的信道配置。
本发明的另一实施例提供了一种上行信道配置方法, 如图 6 所 示, 具体包括以下步骤:
步骤 601、 终端完成接入过程, 基站为终端首次配置上行传输模 式。
上行传输模式包括以下两种:
上行传输模式 1: UE的上行传输具有单载波特性。
UE 上行传输的一个子帧内只能在 PUSCH 上进行数据传输或 PUCCH 上进行数据传输。 当两者同时需要进行数据传输时, 将在 PUCCH进行传输的 UCI插入到 PUSCH中进行传输。
上行传输模式 2: UE的上行传输具有多载波特性。
UE的上行传输的一个子帧内可以同时在 PUSCH和 PUCCH上进 行数据传输。 当然, 也可以通过两者之一进行数据传输。
由于终端采用上行传输模式 1 所需要的功率小于终端采用上行 传输模式 2所需要的功率,优选地,基站为终端配置上行传输模式 1 , 此时基站对 PUSCH和 PUCCH独立进行闭环功率控制。
步骤 602、 基站通过信令通知 UE为其配置的上行传输模式。 优选的, 基站通过高层信令 RRC信令或 MAC信令通知 UE。 步骤 603、 UE接收基站配置的上行传输模式, 并使用该上行传 输模式进行上行传输。
步骤 604、 UE根据上行传输模式计算发射功率裕量 PHR。 当 UE采用上行传输模式 1进行上行传输时, 基站对 PUSCH和 PUCCH独立进行闭环功率控制, PHR的计算公式为:
PH (i) = PCMAX _ PPUSCH (i) (4)
其中, PCMAX为 UE 的最大允许发射功率, 基站对 PUSCH 和 PUCCH独立进行闭环功率控制, PPUSCH(i)为子帧 i中 PUSCH的发射 功率, PH(i)为发射功率裕量, 为 PCMAX与 PPUSCH(i)的差值, 即为 UE 上报给基站的 PHR。
当 UE采用上行传输模式 2进行上行传输时, PHR的计算公式为:
PH (i)― PCMAX ~~ PPUSCH (i) _ Ppuccn (i) (5)
其中, PCMAX为 UE的最大允许发射功率, PPUSCH(i)为子帧 i 中 PUSCH的发射功率, PPUCCH(i)为子帧 i中 PUCCH的发射功率, PH(i) 为发射功率裕量, 为 PCMAX与 PPUSCH(i)和 PPUCCH(i)的差值, 即为 UE 上报给基站的 PHR。 此时, 当 UE的上行子帧中仅在 PUSCH进行传 输时, 公式 5中 PPUCCH(i)为零。
步骤 605、 UE将 PHR发送给基站。
步骤 606、 基站接收 UE上报的 PHR, 设定两个 PHR阈值, 根 据该 PHR进行上行信道配置,其中包括根据 PHR重新配置上行传输 模式。
基站根据该 PHR进行上行信道配置为:由于上行 MCS等级越高, 分配的物理资源越多, 所需要的终端发射功率越大。 所以基站利用 UE上报的 PHR决定下一次上行数据调度的 MCS和资源分配, 以避 免 UE出现发射功率受限问题。
基站根据 PHR重新配置上行传输模式有两种方式, 方式 1为基 站设置一个 PHR 阈值 PHR_thr, 根据 UE上报的 PHR 与该阈值 PHR_thr的关系配置上行传输模式; 方式 2为基站设置两个 PHR阈 值 PHR_thrl和 PHR_thr2, 其中 PHR_thrl<PHR_thr2, 根据 UE上报 的 PHR与 PHR_thrl或 PHR_thr2的关系配置上行传输模式。
本发明实施例中以基站采用方式 2根据 PHR重新配置上行传输 模式为例进行说明。
具体的, 基站采用方式 2根据 PHR重新配置上行传输模式具体 包括以下步骤:
( 1 )基站设置 PHR阈值 PHR_thrl和 PHR_thr2, 该 PHR_thrl 和 PHR_thr2的设置可根据仿真结果或实际测试而得。
( 2 )基站根据 UE上报的 PHR与 PHR_thrl和 PHR_thr2的关系 配置上行传输模式。
当 UE上报的 PHR >阈值 PHR_thr2时, 基站为终端配置上行传 输模式 2;
当 UE上报的 PHR <阈值 PHR_thrl时, 基站为终端配置上行传 输模式 1。
上述判断方式表明, 当 UE上 4艮的 PHR大于阈值 PHR_thr2, 则 说明 PUSCH的发射功率较小, PHR较大, 所以基站为终端配置上行 传输模式 2; 当 UE上报的 PHR小于阈值 PHR_thrl , 则说明 PUSCH 的发射功率较大, PHR较大, 所以基站为终端配置上行传输模式 1。 此外, 由于采用两个 PHR阈值, 避免了 UE在两种上行传输模式之 间频繁的切换。
其中, UE上报的 PHR可以是某一子帧 i的瞬时 PHR, 也可以是 对一段时间的 PHR上报进行平滑后的结果。
步骤 607、 基站判断为终端重新配置的上行传输模式是否与 UE 当前的传输模式相同。
当判断结果为相同时,基站不将所配置的上行传输模式通过信令 通知 UE, 转到步骤 606。
当判断结果为不同时,基站将所配置的上行传输模式通过信令通 知 UE, UE切换至基站配置的该传输模式, 转到步骤 602。
上述上行传输模式的配置与 PHR的计算二个过程是相辅相成的 关系, 当基站配置了上行传输模式, 则 UE根据该上行传输模式计算 PHR; 当 UE计算完 PHR, 基站根据获取的 PHR配置传输模式。 当 UE第一次接入时, 基站为 UE配置上行传输模式, 优选地, 基站为 UE配置上行传输模式 1。
本发明实施例中以基站根据发射功率裕量配置上行传输模式,但 并不限于此,凡是可以表征信道质量好坏的信道质量参数均可以用来 配置上行传输模式。 此外,基站根据信道质量参数不仅可以配置上行 传输模式, 还可以进行其他的信道配置。
