  • CSI Channel State Information
  • the PRACH is mainly used for uplink access of the terminal, and includes sending a preamble (Preamble) on the configured time-frequency resource for random access. After receiving the Preamble sent by the terminal, the base station needs to send the Msg2 message to the terminal for the random access response.
  • the terminal considers that the random access is successful if the terminal receives the Msg2 message, if the terminal is based on the competition random. After receiving the Msg2 message, the terminal also needs to send the Msg3 message for the random access conflict resolution.

  • the control area search space is composed of two parts, one part is a common search space, and one part is a terminal-specific search space.
  • the terminal detects the common search space to obtain some common control information. For example, the terminal needs to detect the downlink control information format 1A (DCI Format 1A) for triggering the non-contention based random access procedure in the common search space, and the terminal needs in the public search space.

  • the PUCCH is only transmitted on the Pcell, and at this time, multiple carriers are simultaneously transmitted and randomly connected.
  • the PUSCHs of multiple carriers are simultaneously transmitted, if the power is limited, that is, the power of multiple PUSCHs exceeds the maximum power value supported by the terminal, the power of the PUSCH with UCI is preferentially guaranteed, and then the PUSCH of other carriers adopts equal power. distribution.

Since the CA scenario mainly considers the ideal backhaul, the scheduling information between multiple carriers is shared, and the power allocation information is also shared with each other in time. At this time, multiple carriers can cooperate with each other to avoid exceeding the maximum power of the terminal. In time, the adjusted values of the corresponding terminals for each carrier and channel can be predicted and calculated between multiple carriers.
  • the two eNBs with dual links adopt non-ideal backhual connections, and the scheduling between the two eNBs is independent. Due to the introduction of independent scheduling, two carriers cannot dynamically share uplink scheduling information and corresponding Power control information. If the two carriers are independently configured with the maximum power value, the uplink power is limited. If independent restrictions are not imposed, the channels configured by the two eNBs will cause the terminal to transmit the power of the channels on the two eNBs and exceed the maximum power value supported by the terminal. At this time, a solution mechanism needs to be introduced to ensure that the terminal can handle such power-limited multi-uplink channel transmission in a dual-link scenario.

Since the PHR between the two eNBs cannot interact in real time, and the scheduling information of the two eNBs cannot be interacted in real time, it is necessary to introduce a PHR enhancement technology to ensure that different eNBs can obtain terminal PHR information more accurately, thereby being more accurate. Double-link scheduling is implemented to reduce performance loss due to power reduction. At the 76th meeting, the following definition is achieved for the dual link.

Description

一种上行功率控制的方法、系统、以及终端和基站 技术领域
本发明涉及长期演进高级系统(LTE-Advanced,Long term evolution advanced system),尤其涉及一种上行功率控制的方法、系统、以及终端和基站。
背景技术
在LTE中,终端的上行信道包括物理上行共享信道(PUSCH)、物理上行控制信道(PUCCH)和物理随机接入信道(PRACH),其中,PUSCH中可以传输数据信息、调度请求(SR)、混合自动重传请求(HARQ)和信道状态信息(CSI),PUCCH中可以传输调度请求(SR)、混合自动重传请求(HARQ)和信道状态信息(CSI)。PRACH主要用于终端的上行接入,包括在配置的时频资源上发送前导码(Preamble)进行随机接入。基站接收到终端发送的Preamble后,需要给终端发送Msg2消息用于随机接入响应,如果终端为基于非竞争随机接入,终端接收到Msg2消息即认为随机接入成功,如果终端为基于竞争随机接入,终端接收到Msg2消息后还需要发送Msg3消息用于随机接入冲突解决,基站接收到终端发送Msg3后需要给终端发送Msg4用于速记接入冲突解决指示,终端接收到基站发送的Msg4中的竞争解决标识和Msg3中的竞争解决标识一致时,终端认为竞争解决成功。
在LTE系统中,控制区域搜索空间由两部分组成,一部分为公共搜索空间,一部分为终端专用搜索空间。终端检测公共搜索空间获得一些公共的控制信息,例如:终端在公共搜索空间需要检测用于触发基于非竞争的随机接入过程的下行控制信息格式1A(DCI Format 1A),终端在公共搜索空间需要检测用于获得系统消息调度信息的DCI Format 1A、DCI Format 1C、 寻呼消息调度信息、随机接入响应信息以及DCI Format3/3A相关的功率控制信息。
下行授权(DL Grant)主要指示终端在对应子帧接收物理下行共享信道(PDSCH),包括:DCI format1、DCI format1A、DCI format1B、DCI format1D、DCI format2、DCI format2A、DCI format2B、DCI format2C、DCI format2D等控制信息,以及当前子帧调度所述终端的PDSCH的资源位置信息、MCS信息、功率控制信息等等。UL Grant主要指上行授权,包括DCI format0、DCI format4、主要指示终端在对应子帧发送PUSCH,其中包括对应子帧所述终端发送PUSCH的资源位置信息以及MCS信息,功率控制信息等等。
在现有技术中,CA场景下,如果多个分量载波出现聚合发送,由于随机接入仅仅在Pcell上发送,PUCCH也仅仅在Pcell上发送,这时不会出现多个载波上同时发送随机接入信道以及PUCCH的过程。当多个载波的PUSCH同时传输时,如果功率受限,即多个PUSCH的功率和超出了终端支持的最大功率值,则优先保证带有UCI的PUSCH的功率,然后其他载波的PUSCH采用等功率分配。当PUCCH和PUSCH同时传输时,如果功率受限,即PUCCH和一个或者多个PUSCH的功率和超出了终端支持的最大功率值,首先保证PUCCH的功率,其次保证带有UCI的PUSCH的功率,然后其他PUSCH采用等功率分配。由于CA场景主要考虑理想回程线路(backhual),多个载波间的调度信息共享,功率分配信息也相互及时共享,这时多个载波间可以相互协作避免超出终端的最大功率,当超出终端最大功率时,多个载波间可以预测并且计算对应的终端对于各个载波和信道的调整值。
在R12阶段考虑引入双链接技术,双链接技术与CA的最大区别在于:双链接的两个eNB采用了非理想backhual连接,两个eNB之间的调度独立。由于引入了独立调度,两个载波不能动态的共享上行调度信息以及对应的 功率控制信息,这时如果两个载波独立配置最大功率值,会导致上行功率受限浪费。如果不进行独立限制,两个eNB配置的信道会导致终端发送两个eNB上的信道的功率和超出终端支持的最大功率值。这时需要引入一种解决机制,来保证终端在双链接场景下,可以处理这种功率受限的多上行信道发送。
在LTE讨论时期,为了使得基站获得更准确的PUSCH功率控制信息和终端的功率余量,终端需要周期性或者基于事件触发的方式给基站侧反馈功率余量报告(PHR,Power Headroom Report)。基站在获得PHR后,可以更准确的调整PUSCH的调制编码机制(MCS)、资源分配以及动态功率调整因子。
在LTE-A R10CA讨论时期,由于引入了PUCCH和PUSCH可以在同一个子帧传输,这时需要引入PUCCH和PUSCH同时传输的PHR报告,所以在R10CA阶段引入了两种PHR报告类型,分别为Type1PHR和Type2PHR。
在R12阶段考虑引入双链接技术,双链接技术与CA的最大区别在于双链接的两个eNB采用了非理想backhual连接,两个eNB之间的调度独立。由于两个eNB间的PHR不能实时的交互,并且两个eNB的调度信息不能实时进行交互,所以需要引入一种PHR增强技术,来保证不同eNB可以比较精确的获得终端PHR信息,从而更准确的实现双链接调度,减少由于功率削减带来的性能损失。76次会议上,对于双链接达成了以下定义方式,双链接的终端可以配置两个小区组,一个为宏小区基站(MeNB)对应的小区组(MCG),另外一个为源基站(SeNB)对应的小区组(SCG),MCG中包括一个MeNB的主服务小区(MPcell)和多个MCCs,SCG中包括一个SeNB的主服务小区(SPcell)和多个SCCs。其中MPcell为MCG的主服务小区,所有MCG下的服务小区对应的PUCCH都应该在MPcell上发送,SPcell为SCG的主服务小区,所有SCG下的服务小区对应的PUCCH 都应该在SPcell上发送。

具体实施方式
在双链接场景存在至少两个基站(eNB),分别称为MeNB和SeNB,MeNB为主服务基站,SeNB为非主服务基站(或者称为辅服务基站),MeNB可以负责给终端发送SeNB的一些系统消息和一些高层配置信令,MeNB和SeNB可以实现独立的MAC层调度。
MeNB下可以配置多个服务小区(载波),其中一个为MeNB的主服务小区,称为MPcell,其他小区为MCCs。MeNB下所有服务小区的上行PUCCH,仅仅在MPcell对应的载波上传输,而且终端仅仅在MPcell上检测MeNB的系统信息和寻呼消息。
SeNB下可以配置多个服务小区(载波),其中一个为SeNB的主服务小区,称为SPcell,其他小区为SCCs。SeNB下所有服务小区的上行PUCCH,仅仅在SPcell对应的载波上传输。
假设双链接终端UE,分别接入MeNB和SeNB,终端在上报PHR时,需要给MeNB上报一个对于MeNB和MeNB+SeNB的两个PHR信息,分别标记为PHR0和PHR2,需要给SeNB上报一个对于SeNB和SeNB+MeNB的两个PHR信息,分别标记为PHR1和PHR2。
或者,终端在上报PHR时,需要给MeNB上报一个对于MeNB和SeNB,的两个PHR信息,分别标记为PHR0和MPHRS,需要给SeNB上报一个对于SeNB和MeNB的两个PHR信息,分别标记为PHR1和SPHRS。
MPHRS可以为对于SeNB上各个服务小区基于多个子帧计算的统计PHR,SPHRS可以为对于MeNB和上各个服务小区基于多个子帧计算的统计PHR。
MPHRS可以为对于SeNB上所有服务小区基于多个子帧和所有服务小区计算的统计PHR,SPHRS可以为对于MeNB上各个服务小区基于多个子 帧和所有服务小区计算的统计PHR。
这样在MeNB侧可以获得单独调度MeNB UL的PHR信息以及同时传输MeNB和SeNB上行信道的PHR信息,从而MeNB可以计算单独传输MeNB上行信道的功率调整因子和/或对应于MeNB的PUSCH采用的动态信息(至少包括调度带宽、MCS、动态功率调整因子)以及半静态信息(至少包括路损校正因子、动态功率调整因子、终端归一化控制因子)等等。另外MeNB可以计算出同时传输MeNB和SeNB上行信道的功率调整因子和/或对应于MeNB的PUSCH采用的动态信息(至少包括调度带宽、MCS、动态功率调整因子)以及半静态信息(至少包括路损校正因子、动态功率调整因子、终端归一化控制因子)等等。SeNB采用同MeNB相同的实现方法,计算出单独调度SeNB UL的功率调整因子以及对应于SeNB的PUSCH采用的动态信息(调度带宽、MCS、动态功率调整因子)以及半静态信息(路损校正因子、动态功率调整因子、终端归一化控制因子)等等。另外SeNB可以计算出同时传输SeNB和MeNB UL的功率调整因子以及对应于SeNB的PUSCH采用的动态信息(调度带宽、MCS、动态功率调整因子)以及半静态信息(路损校正因子、动态功率调整因子、终端归一化控制因子)等等。

其中,所述UL Grant至少包括以下DCI Format之一:DCI Format0、DCI Format4。
实施例十三:
基于实施例一~实施例十二,其中同时传输的功率控制信令也可以通过PDCCH或EPDCCH所在候选集合的位置指示。例如:将PDCCH的候选CCE集合分为两个组:组0和组1,如果终端检测到PDCCH CCE位于组0,那么说明如果发生同时传输采用组0对应的功率调整因子和/或MCS信息,如果终端检测到PDCCH CCE位于组1,那么说明如果发生同时传输采用组1对应的功率调整因子和/或MCS信息。
实施例十四:
基于实施例一~实施例十二,其中同时传输的功率控制信令也可以通过PDCCH或EPDCCH所在候选集合的位置和聚合级别集合指示。例如:将PDCCH的候选CCE位置集合和聚合级别分为两个组:组0和组1,如果终端检测到PDCCH CCE和聚合级别位于组0,那么说明如果发生同时传输采用组0对应的功率调整因子和/或MCS信息,如果终端检测到PDCCH CCE和聚合级别位于组1,那么说明如果发生同时传输采用组1对应的功率调整因子和/或MCS信息。
实施例十五:
基于实施例一~实施例十四,由于MeNB和SeNB发送完对应的DL Grant或UL Grant后,并不知道对应的调度子帧是否会发生同时重传,所以MeNB和SeNB需要按照配置的两种功率调整因子和/或MCS信息进行PUCCH和PUSCH的检测和接收。
实施例十六:
当终端按照eNB配置的同时传输的功率调整因子进行上行功率调整后,同时传输两个eNB的上行信道的功率和仍然超过终端最大支持的发送功率时,终端可以按照优先级选择丢弃低优先级上行信道的传输或者进行功率削减调整,这里,对于功率削减调整可以优先保证优先级高的上行信道的发送功率。
实施例十七:
假设双链接终端UE,分别接入MeNB和SeNB,终端在上报PHR时,需要给MeNB上报一个对于MeNB和MeNB+SeNB的两个PHR信息,分别标记为PHR0和PHR2需要给SeNB上报一个对于SeNB和SeNB+MeNB的两个PHR信息,分别标记为PHR1和PHR2,这样减小了终端计算复杂度,仅仅计算两种PHR即可。在MeNB侧可以获得单独调度MeNB UL的PHR信息PHR0以及同时传输MeNB UL和SeNB UL的PHR信息PHR2,从而MeNB可以根据PHR0计算单独调度MeNB UL的PHR偏置值。另外,MeNB可以根据PHR2计算出同时传输MeNB UL和SeNB UL的PHR偏置值。SeNB采用同MeNB相同的实现方法,计算出单独调度SeNB UL的PHR偏置值,另外SeNB可以根据PHR2计算出同时传输SeNB UL和MeNB UL的PHR偏置值。
实施例十八:
基站可以采用公共搜索空间区域的功率控制命令和DL/UL Grant中的TPC命令联合编码的方式,指示单独调度对应的MeNB或SeNB的 PUCCH/PUSCH的发送功率和混合调度MeNB和SeNB的PUCCH/PUSCH的发送功率。
终端通过检测公共搜索空间区域的功率控制命令和检测PDCCH区域获得DL/UL Grant中的TPC命令,利用预定义的联合编码的方式,获得发送PUCCH/PUSCH采用的功率级别。
实施例十九:
基于实施例一~实施例十六,其中功率调整因子和MCS可以指示一个范围,用来通知终端,在进行功率削减或者MCS发送时,只能在对应的范围内进行调整。
