- a technical challenge faced by high-frequency carrier communication is that relatively low-frequency signals, high-frequency signals have large fading in space, which may cause spatial fading loss problems in high-frequency signals in outdoor communication. Due to the reduction in the wavelength of the high frequency signal, more antennas can be used so that communication can be based on the beam to compensate for fading losses in space.

说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不限于清楚地列出的那些步骤或单元。
LTE系统或LTE-A系统中,同小区内多个不同用户之间的上行数据是正交的,因此,LTE系统(或LTE-A系统)采用慢速的上行功率控制。采用慢速的上行功率控制可以通过功率控制使得上行传输适应不同的无线传输环境,如路损(Path loss,PL)环境或阴影衰落环境。LTE功率控制的对象包括物理上行链路控制信道(Physical Uplink Control CHannel,PUCCH),物理上行共享信道(Physical Uplink Shared Channel,PUSCH)以及探测参考信号(Sounding Reference Signal,SRS)。虽然这些上行信号的数据速率和重要性不同,这些上行信号的功控方法和参数也不尽相同。但这些上行信号的控制原理基本相同的,该原理可以归纳为:
UE发射的功率谱密度(即每个资源块(resource block,RB)上的功率)= 开环工控点+动态的功率偏移。其中,开环工控点=目标功率P0+开环的路损补偿α×(PL)。目标功率P0又分为小区目标功率和UE特定的目标功率两部分。
开环的PL基于UE对于下行的路损估计。UE通过测量下行参考信号参考信号接收功率(Reference Signal Received Power,RSRP),并与已知的参考信号(Reference Signal,RS)(参考信号基站发送的时候用了多少功率,通过信令通知终端)的信号功率相减,从而进行路损估计。
对于PUSCH和SRS,eNodeB(即eNB)通过路损补偿因子α来决定路损在UE的上行功率控制中的权重。比如说,对于处于小区边缘的UE,如果其发送功率过高,会对别的小区造成干扰,从而降低整个系统的容量。对于PUCCH来说,由于不同的PUCCH用户是码分复用的,α取值为1,可以更好地控制不同PUCCH用户之间的干扰。
动态的功率偏移包含两个部分,基于调制编码方式(Modulation Coding Scheme,MCS)的功率调整ΔTF和闭环的功率控制。基于调制与编码策略(Modulation and Coding Scheme,MCS)的功率调整可以使得UE根据选定的MCS来动态地调整相应的发射功率谱密度。闭环的功率控制是指UE通过PDCCH中的传输功率控制(Transmitting Power Command,TPC)传输功率命令来对UE的发射功率进行调整。调整策略可以分为累积调整和绝对值调整两种方式。累积调整方式适用于PUSCH,PUCCH和SRS,绝对值调整方式只适用于PUSCH。这两种不同的调整方式之间的转换是半静态的,eNB通过专用无线资源控制(Radio Resource Control,RRC)信令指示UE采用累积方式还是绝对值方式。
累积方式是指当前功率调整值是在上次功率调整的数值上增加或减少一个TPC中指示的调整步长,累积方式是UE缺省使用的调整方式。LTE中累积方式的TPC可以有两套不同的调整步长,第一套步长为(-1,0,1,3)dB,对于PUSCH,由DCI format 0或3指示。对于PUCCH,由DCI format 1、1A、1B、1D、2、2A或3指示。第二套步长为(-1,1),由DCI format 3A指示(适用于PUCCH和PUSCH)。
绝对值方式是指直接使用TPC中指示的功率调整数值,只适用于 PUSCH。此时,eNodeB可以通过RRC信令显式地关闭累积方式地功率调整方式。当采用绝对值方式时,TPC数值为(-4,-1,1,4)dB,由DCI format 0或3指示,功率调整的范围可达8db,该方式适用于UE不连续的上行传输的情况,可以使得eNodeB一步调整UE的发射功率至期望值。
随着通信技术的发展,数据业务需求量不断增加,可用的低频载波也已经非常稀缺,由此,基于还未充分利用的高频(30~300GHz)载波通信成为解决未来高速数据通信的通信手段之一。高频载波通信的可用带宽很大,可以提供高速数据通信。但是,高频载波通信面临的一个技术挑战是:相对低频信号,高频信号在空间的衰落大,可能导致高频信号在室外的通信出现了空间的衰落损耗问题。由于高频信号波长的减小,可以使用更多的天线,从而可以基于波束进行通信以补偿在空间的衰落损耗。
但是,当天线数增多时,由于每个天线对应各自的一套射频链路,基于数字波束成型的方法增加了成本和增大了功率损耗。因此,相关技术中倾向于采用混合波束赋形,即射频波束和数字波束共同形成最终的波束。
在新的无线接入技术(New Radio Access Technology,NRAT)的研究中,高频通信系统除了基站会配置大量的天线形成下行传输波束以补偿高频通信的空间衰落,终端同样也会配置大量的天线形成上行传输波束,基站侧也会选择合适的接收波束以匹配接收上行信号。在一些研究中,终端可以使用两种不同的传输波形,分别为离散傅里叶变换扩频的正交频分复用(Signal Carrier Frequency Division Multiple Access,DFT-S-OFDM)和循环前缀正交频分复用(Cyclic Prefix Orthogonal Frequency Division Multiplexing,CP-OFDM),此时不同的传输波形应有不同的上行功控策略。测量参考信号(Sounding Reference Signal,SRS)除了可用于测量信道信息,还可用于上行波束扫描或波束跟踪,因此对于SRS的发送,需要更灵活的SRS功控策略。
基站可以为宏小区的基站、小小区(small cell)的基站或传输节点、高频通信系统中的发送节点、物联网系统中的发送节点等发送和控制终端的设备节点。终端可以为用户终端(UE)、手机、便携设备、汽车等通信系统中的接收节点。总之,所述基站可以为发送指示发送方式信令的发送节点,所述终端可为接收所述信令的接收节点。

例如,终端的1个码字流或传输块映射到两层,第1层使用QPSK的调制方式,第2层使用16QAM的调制方式,则第1层的发送功率计算可以为:
UE发射的功率谱密度(即每RB上的功率)=目标功率P0+开环的路损补偿α×(PL)+动态的上行发送功率调整值
第1层的发送功率计算可以为:
UE发射的功率谱密度(即每RB上的功率)=目标功率P0+开环的路损补偿α×(PL)+3dB+动态的上行发送功率调整值
即第1层和第2层的功率差异在于第2层的发送功率使用的3dB的功率偏置值。
一实施例中,基站通过无线资源控制(Radio Resource Control,RRC)信令或介质访问控制控制单元(Media Access Control Control Element,MAC CE)信令配置上行发送功率调整值在多个空间复用层之间的分配比例,通过物理下行控制信令指示上行发送功率调整值。
例如,假定用户终端上行使用了2个发送层,分别为层1和层2,上行发送功率调整值在这2个发送层之间的分配比例为1∶2,基站通过下行控制信令为用户终端指示总的上行发送功率调整值为3dBm,则在发送层1上的发送功率调整值为1dBm,在发送层2上的发送功率调整值为2dBm。
一实施例中,基站通过RRC信令或MAC CE信令配置空间复用层的功率调整使能位,通过物理下行控制信令指示上行发送功率调整值。
假定用户终端上行使用了4个发送层,分别为发送层1、发送层2、发送层3和发送层4,发送层的功率调整使能位为1010,基站通过下行控制信令为用户终端指示总的上行发送功率调整值为3dB,则在发送层1上的发送功率调整值为3dB,在发送层2上不进行发送功率调整,在发送层3上的发送功率调整值为3dB,在发送层4上不进行发送功率调整。如果发送波束的功率调整使能位或发送波束的位图为1000,基站通过下行控制信令为用户终端指示总的上行发送功率调整值为3dB,则在发送层1上的发送功率调整值为3dB,在发送层2、发送层3和发送层4上不进行发送功率调整。
一实施例中,终端在不同的接收方式上接收来自不同发送方式或不同基站或不同发送节点的参考信号,以确定参考信号的接收功率(Reference Signal Received Power,RSRP),来自不同发送方式或不同基站或不同发送节点的RSRP使用不同的功率偏置值。
例如,在异构网中,终端既要对宏基站的下行导频进行RSRP的测量,又要对小小区small cell的基站发送的下行导频进行RSRP测量,以确定终端接入小小区还是宏小区。为了降低宏小区的用户数或业务量,终端会在测到的来自小小区的RSRP基础上增加一个功率偏置值L,作为最终的来自小小区的RSRP。 这种方式会增加终端接入小小区的概率,降低宏小区的业务量,从而平衡宏小区和小小区的业务。
