Description

数据传输的功率控制方法和装置 技术领域
本发明涉及通信领域，并且更具体地，涉及一种数据传输的功率控制方法和装置。
背景技术
在长期演进(Long Term Evolution，LTE)系统中，当需要传输上行数据时，用户设备(User Equipment，UE)采用上行调度请求(Scheduling Request，SR)机制。UE通过发送上行调度请求给基站，告知基站UE需要上行资源进行数据传输。基站接收到UE的调度请求后，给UE分配一定的资源，UE在这些分配的资源上进行数据传输。但是该种机制导致大量的信令开销。
为了解决上述问题，已经提出了一种上行非授权(Grant Free)的技术方案。Grant Free是指在公共陆地移动网络(Public Land Mobile Network，PLMN)中，UE无需通过调度请求方式请求基站分配资源进行数据传输Grant Free用户可以根据传输数据的特点的不同，如传输时延或可靠性的要求，可以直接采用免授权传输方式在竞争传输资源(Contention Transmission Unit，CTU)上传输报文。
在现有LTE系统中，用户设备在通信时需要与无线通信网络建立无线资源控制(Radio Resource Control，RRC)连接，并且移动性管理实体(Mobility Management Entity，MME)根据归属位置寄存器(Home Location Register，HLR)中记录的用户设备的信息完成对用户设备的认证和鉴权。用户设备、基站、服务网关(Serving Gateway，S-GW)以及公共数据网(Public Data Network，PDN)网关(PDN Gateway，P-GW)之间需要建立承载通道，以便业务数据流在所建立的承载通道中传输。另外，用户设备和网络设备还需要建立协议栈上下文，包括分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)、无线链路层(Radio Link Control，RLC)、媒体接入控制(Medium Access Control，MAC)、物理层(Physical layer，PHY)等实体。为了保证数据传输的完整性和安全性，用户设备在PDCP实体中进行完整性保护(Integrity Protection)和加解密过程(Ciphering Process)。
在免授权(Grant Free，GF)传输场景下，用户设备可能处于空闲态，也可能处于连接态。在连接态时，用户设备和网络设备可以维护空口传输所需要的上下文资源，即PDCP、RLC、MAC、PHY实体，从而保证数据传输的完整性和安全性。这样，冗余的协议栈的附加信息会导致传输效率的降低。而在空闲态，用户设备不需要建立与网络侧的RRC连接，可以直接采用免授权传输方式在竞争传输资源(Contention Transmission Unit，CTU)上传输报文。这种技术方案简单和有效，但相比于授权传输，非授权传输有很大的不确定性，不能终端可能使用相同的资源进行上行传输，从而导致的小区用户间干扰和邻区干扰相比授权传输更为严重，从而如何减少干扰是一项亟待解决的问题。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本说明书中使用的术语“部件”、“模块”、“系统”等用于表示计算机相关的实体、硬件、固件、硬件和软件的组合、软件、或执行中的软件。例如，部件可以是但不限于，在处理器上运行的进程、处理器、对象、可执行文件、执行线程、程序和/或计算机。通过图示，在计算设备上运行的应用和计算设备都可以是部件。一个或多个部件可驻留在进程和/或执行线程中，部件可位于一个计算机上和/或分布在2个或更多个计算机之间。此外，这些部件可从在上面存储有各种数据结构的各种计算机可读介质执行。部件可例如根据具有一个或多个数据分组(例如来自与本地系统、分布式系统和/或网络间的另一部件交互的二个部件的数据，例如通过信号与其它系统交互的互联网)的信号通过本地和/或远程进程来通信。
应理解，本发明实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile Communication，简称为“GSM”)系统、码分多址(Code Division Multiple Access，简称为“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access，简称为“WCDMA”)系统、长期演进(Long Term Evolution，简称为“LTE”)系统、LTE频分双工(Frequency Division Duplex，简称为“FDD”)系统、LTE时分双工(Time Division Duplex，简称为“TDD”)、通用移动通信系统(Universal Mobile Telecommunication System，简称为“UMTS”)、以及未来的5G通信系统等。
本发明结合终端设备描述了各个实施例。终端设备也可以指用户设备(User Equipment，简称为“UE”)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，简称为“SIP”)电话、无线本地环路(Wireless Local Loop，简称为“WLL”)站、个人数字处理(Personal Digital Assistant，简称为“PDA”)、具有无线通信功能的手持设备、计算设备或连接到无线调 制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的PLMN网络中的终端设备等。
本发明结合网络设备描述了各个实施例。网络设备可以是用于与终端设备进行通信的设备，例如，可以是GSM系统或CDMA中的基站(Base Transceiver Station，简称为“BTS”)，也可以是WCDMA系统中的基站(NodeB，简称为“NB”)，还可以是LTE系统中的演进型基站(Evolutional Node B，简称为“eNB”或“eNodeB”)，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的核心网设备或未来演进的PLMN网络中的网络设备等。
此外，本发明的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，CD(Compact Disk，压缩盘)、DVD(Digital Versatile Disk，数字通用盘)等)，智能卡和闪存器件(例如，EPROM(Erasable Programmable Read-Only Memory，可擦写可编程只读存储器)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
现有的蜂窝通信系统，如GSM、WCDMA、LTE等系统中，所支持的通信主要是针对语音和数据通信的。通常来说，一个传统基站支持的连接数有限，也易于实现。
下一代移动通信系统将不仅支持传统的通信，还将支持机器到机器(Machine to Machine，简称为“M2M”)通信，或者叫做机器类通信(Machine Type Communication，简称为“MTC”)通信。根据预测，到2020年，连接在网络上的MTC设备将会达到500到1000亿，这将远超现在的连接数。对M2M类业务，由于其业务种类千差万别，对网络需求存在很大差异。大致来说，会存在如下几种需求：(I)可靠传输，但对时延不敏感；(II)低延迟，高可靠传输。
对可靠传输，而对时延不敏感业务，较容易处理。但是，对低延迟、高可靠传输类的业务，不仅要求传输时延短，而且要求可靠，比如V2V(英文 全称为：Vehicle to Vehicle)业务。如果传输不可靠，会导致重传而造成传输时延过大，不能满足要求。
由于大量连接的存在，使得未来的无线通信系统和现有的通信系统存在很大差异。大量连接需要消耗更多的资源接入终端设备以及需要消耗更多的资源用于终端设备的数据传输相关的调度信令的传输。

本发明结合终端设备描述了各个实施例。终端设备也可以指用户设备(User Equipment，简称为“UE”)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议 (Session Initiation Protocol，简称为“SIP”)电话、无线本地环路(Wireless Local Loop，简称为“WLL”)站、个人数字处理(Personal Digital Assistant，简称为“PDA”)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的PLMN网络中的终端设备等。

此外，本发明的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，CD(Compact Disk，压缩盘)、DVD(Digital Versatile Disk，数字通用盘)等)，智能卡和闪存器件(例如，EPROM(Erasable Programmable Read-Only Memory，可擦写可编程只读存储器)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。

由于大量连接的存在，使得未来的无线通信系统和现有的通信系统存在很大差异。大量连接需要消耗更多的资源接入UE以及需要消耗更多的资源用于终端设备的数据传输相关的调度信令的传输。
图1示出了应用本发明实施例的一种通信系统的示意性架构图。如图1所示，该通信系统100可以包括网络设备102和终端设备104～114(图中简称为UE)通过无线连接或有线连接或其它方式连接。
本发明实施例中的网络可以是指公共陆地移动网络(Public Land Mobile Network，简称为“PLMN”)或者D2D网络或者M2M网络或者其他网络，图1只是举例的简化示意图，网络中还可以包括其他网络设备，图1中未予以画出。
为了解决未来网络大量的MTC类业务，以及满足低时延、高可靠的业务传输，本发明提出了免授权(UL Grant Free)传输的一种方案。这里的免授权传输可以针对的是上行数据传输。UL Grant Free传输可以理解为如下含义中的任意一种含义，或，多种含义，或者多种含义中的部分技术特征的组合：
1、免授权传输可以指：网络设备预先分配并告知终端设备多个传输资源；终端设备有上行数据传输需求时，从网络设备预先分配的多个传输资源中选择至少一个传输资源，使用所选择的传输资源发送上行数据；网络设备在所述预先分配的多个传输资源中的一个或多个传输资源上检测终端设备发送的上行数据。所述检测可以是盲检测，也可能根据所述上行数据中某一个控制域进行检测，或者是其他方式进行检测。
2、免授权传输可以指：网络设备预先分配并告知终端设备多个传输资源，以使终端设备有上行数据传输需求时，从网络设备预先分配的多个传输资源中选择至少一个传输资源，使用所选择的传输资源发送上行数据。
3、免授权传输可以指：获取预先分配的多个传输资源的信息，在有上行数据传输需求时，从所述多个传输资源中选择至少一个传输资源，使用所 选择的传输资源发送上行数据。获取的方式可以从网络设备获取。
4、免授权传输可以指：不需要网络设备动态调度即可实现终端设备的上行数据传输的方法，所述动态调度可以是指网络设备为终端设备的每次上行数据传输通过信令来指示传输资源的一种调度方式。可选地，实现终端设备的上行数据传输可以理解为允许两个或两个以上终端设备的数据在相同的时频资源上进行上行数据传输。可选地，所述传输资源可以是UE接收所述的信令的时刻以后的一个或多个传输时间单位的传输资源。一个传输时间单位可以是指一次传输的最小时间单元，比如传输时间间隔(Transmission Time Interval，简称为“TTI”)，数值可以为1ms,或者可以是预先设定的传输时间单元。
5、免授权传输可以指：终端设备在不需要网络设备授权的情况下进行上行数据传输。所述授权可以指终端设备发送上行调度请求给网络设备，网络设备接收调度请求后，向终端设备发送上行授权，其中所述上行授权指示分配给终端设备的上行传输资源。
6、免授权传输可以指：一种竞争传输方式，具体地可以指多个终端在预先分配的相同的时频资源上同时进行上行数据传输，而无需基站进行授权。
所述的数据可以为包括业务数据或者信令数据。
所述盲检测可以理解为在不预知是否有数据到达的情况下，对可能到达的数据进行的检测。所述盲检测也可以理解为没有显式的信令指示下的检测。
所述传输资源可以包括但不限于如下资源的一种或多种的组合：时域资源，如无线帧、子帧、符号等；频域资源，如子载波、资源块等；空域资源，如发送天线、波束等；码域资源，如稀疏码多址接入(Sparse Code Multiple Access，简称为“SCMA”)码本组、低密度签名(Low Density Signature，简称为“LDS”)组、CDMA码组等；上行导频资源。
如上的传输资源可以根据包括但不限于如下的控制机制进行的传输：上行功率控制，如上行发送功率上限控制等；调制编码方式设置，如传输块大小、码率、调制阶数设置等；重传机制，如HARQ机制等。
竞争传输单元(英文全称可以为：Contention Transmission Unit，英文缩写可以为：CTU)可以为免授权传输的基本传输资源。CTU可以指时间、频 率、码域相结合的传输资源，或者，可以指时间、频率、导频相结合的传输，或者，可以指时间、频率、码域、导频相结合的传输资源。
CTU的接入区域可以指用于免授权传输的时频区域。
终端设备在进行免授权传输时，可能处于连接态，也可能处于空闲态。在空闲态下，由于终端设备和网络设备中的上下文资源已经释放，在采用免授权传输方式传输报文时，连接态下所使用的加解密密钥不能再使用，因而不能保证数据传输的安全。其次，在免授权传输方式下，不希望有冗余的协议栈附加信息导致传输效率的降低，协议栈应该尽量简单高效。另外，连接态下的网络设备通过为终端设备临时分配小区无线网络临时识别(Cell RNTI，CRNTI)来识别用户，而空闲态的GF传输也无法使用连接态下的CRNTI来识别用户。如果终端设备在进行GF传输时，不做任何封装，将应用层的IP报文直接转发，能够实现简单高效的传输。但是，在GF传输中，CTU资源不是基站分配给终端设备单独使用的，而是可以由多个终端设备同时竞争使用的，这样很容易造成其他终端设备的报文伪装或攻击，对安全造成影响。
图2是根据本发明的另一实施例的通信系统200的架构示意图。
系统200包括低延迟服务功能(Low Delay Service Function，LDSF)实体210、基站230、MME/HLR/归属用户服务器(Home Subscriber Server，HSS)120、服务网关(Serving GateWay，S-GW)/公共数据网络网关(Public Data Network GateWay，P-GW)250等网络节点。用户设备240通过空口与基站230通信。LDSF 210可以是逻辑功能实体，也可以实际的物理设备。LDSF主要负责免授权传输的两个子功能，分别是为支持免授权传输的用户设备进行身份注册的功能和分发免授权传输数据(例如，报文)的功能。
例如，当用户设备进行免授权传输时，用户设备通过基站向LDSF请求注册免授权传输的身份，LDSF会为用户设备分配专用于免授权传输的密钥和用户设备标识。用户设备利用该密钥和用户设备标识对数据进行加密和封装，并采用免授权传输方式传输数据。基站接收到用户设备采用免授权方式传输的数据后，将该数据发送给LDSF，LDSF根据数据中携带的目标地址分发数据。
应理解，本发明的实施例的LDSF可以是MME或者其它核心网设备的逻辑功能实体。在下文中，为了描述方便，如果没有特殊说明以LDSF为独 立的物理设备为例进行说明。
应理解，系统200可以包括至少一个LDSF，每个基站与至少一个LDSF连接，基站在启动后与LDSF之间保持非授权传输报文的传输通道。例如，当LDSF为MME的逻辑功能实体时，LDSF与网络设备之间的接口为S1接口，当LDSF为独立的物理设备时，LDSF与网络设备之间可以通过与S1接口类似的接口进行连接。
还应理解，图1的实施例是以网络设备为基站为例进行描述，网络设备也可以是其它接入设备(例如，无线接入点)。
为了便于理解本发明，以下将对本发明实施例中的术语进行说明。
基站为所管辖的每个小区配置一个或多个竞争传输单元，每个竞争传输单元的限定条件包括传输资源，该传输资源包括时域资源(如无线帧、子帧或符号等)、频域资源(如子载波或资源块等)和空域资源(如发送天线或波束等)中的至少一种，则基站下发的竞争传输单元的配置信息可以包括传输资源的信息。从而，具有非授权传输能力的且使用非授权传输模式的终端可以从一个或多个竞争传输单元中选择一个竞争传输单元，从利用其相应的传输资源进行上行传输。
应理解，从终端的角度来说，终端所能识别的是小区，包括服务小区和邻区等。因此，竞争传输单元实际上是针对小区而言的，即基站的竞争传输单元等价为基站所管辖小区的非授权区域，基站配置竞争传输单元等价为基站为所管辖的小区配置竞争传输单元。
可选地，在具体实现时，通常可以采用两种方式配置基站的竞争传输单元。一种是分布式方式，即基站自行配置所管辖小区的竞争传输单元；另一种是集中式分布，即存在中心单元(Central Unit，简称CU)，统一配置中心单元所管辖范围内的各基站的竞争传输单元。该中心单元为逻辑实体，其物理实体可以位于现有的核心网网元，如移动性管理实体(Mobility Management Entity，MME)，服务网关(Serving GateWay，S-GW)或者公共数据网络网关(Public Data Network GateWay，PDN-GW)，也可以是独立的核心网网元，也可以位于基站。同样需要注意的是，在系统实现或标准规范中，该中心单元可能会以其他名称出现，但应理解为相同的逻辑实体。
应当注意的是，具体到系统实现或标准规范中，竞争传输单元可能会以其他名称出现，如竞争传输区域、竞争传输单元等，但应理解为相同的概念。
图3是根据本发明的一个实施例的CTU资源定义的示意图。
图3示出了四个竞争接入区域(也称为CTU接入区域)310、320、330和340，而可用带宽被分成四个竞争接入区域的时频区域。每个竞争接入区域可以占用预定数量的资源块(Resource Block)，例如，在图3的实施例中，竞争接入区310包括四个RB：RB1、RB2、RB3和RB4。本发明的实施例并不限于此，例如，不同的竞争接入区域可以包括不同数目的RB。在图3中，每个竞争接入区域能够支持36个UE竞争该竞争区域中定义的36个CTU，每个CTU是时间、频率、码资源或签名和导频的结合。码资源包括CDMA码，或SCMA(Sparse Code Multiple Access)码或LDS(Low Density Signature)或其它签名(signature)等。每个竞争接入区域占用一个时频资源区，每个时频资源区支持六个签名(S1-S6)，并且每个签名映射到6个导频，从而生成总共36个导频(P1-P36)。网络设备可以使用导频/签名解相关器来检测或解码各个UE在CTU上发送的信号。
UE进入源网络设备的覆盖区时，可以接收到网络设备发送的高层信令。该高层信令可以携带CTU接入区域定义(CTU access region definition)、CTU的总数、默认映射规则等等。可替代地，UE也可预先配置默认映射规则。UE可以确定一个合适的CTU以在该CTU上进行免授权传输。当不同的UE在相同的CTU进行免授权传输时，即竞争相同的CTU时，会出现冲突。UE可以根据网络设备的指示确定是否存在冲突。例如，可以采用异步HARQ方法解决冲突引起的问题。然而，如果冲突的次数超过预定的阈值，则可以请求网络设备重新映射CTU。网络设备将重新映射后的CTU的信息发送给UE，以便UE在重新映射后的CTU上进行免授权传输。
应理解，为了描述方便，图3示出了四个竞争接入区域，本发明的实施例并不限于此，可以根据需要定义更多或更少的竞争接入区域。
专利号PCT/CN2014/073084，申请名称为“System and Method for Uplink Grant-free Transmission Scheme”的专利申请给出了一种上行免授权传输的技术方案。PCT/CN2014/073084申请介绍可以将无线资源划分为各种CTU，UE被映射到某个CTU。每个CTU可以被分配一组码，所分配的一组码可以是一组CDMA码，也可以是SCMA码本集或LDS组或签名(signature)组等。每一个码可以对应一组导频。用户可以选择一个码以及与该码对应的导频组中的一个导频进行上行传输。PCT/CN2014/073084申请内容也可以理解 为通过引用作为本发明实施例内容的一部分，不再赘述。
图4是根据本发明实施例的数据传输的功率控制方法400的示意性流程图。如图4所示，该方法400包括：
410，确定第一竞争传输单元的配置信息，该第一竞争传输单元的配置信息包括功率控制信息，其中，竞争传输单元为至少由时域、频域和码域组成的传输资源，该第一竞争传输单元的功率控制信息用于控制终端使用该第一竞争传输单元发送上行数据时所采用的功率；
420，向终端发送该第一竞争传输单元的配置信息。
具体地说，基站可以确定所管辖的某一小区对应的某一竞争传输单元的配置信息，其中，该配置信息包括功率控制信息，该功率控制信息用于控制终端使用该竞争传输单元发送上行数据时所采用的功率，然后向终端发送该配置信息，从而终端可以根据配置信息中的功率控制信息，确定使用该竞争传输单元进行上行传输时的功率，从进行上行传输。
因此，由于在竞争传输单元的配置信息中携带针对该竞争传输单元的功率控制信息，终端可以根据配置信息中的功率控制信息，确定使用该竞争传输单元进行上行传输时的功率，从而可以实现上行传输功率的可控，并且可以进一步通过控制上行传输的功率，来实现减少小区用户间干扰和邻区干扰。
可选地，在本发明实施例中，终端接收到配置信息，可以进行上行免授权传输，该免授权传输为网络设备预先分配并告知终端设备多个CTU，以使终端设备有上行数据传输需求时，从网络设备预先分配的多个CTU中选择至少一个CTU，并使用所选择的CTU发送上行数据。
可选地，在本发明实施例中，竞争传输单元的功率控制信息可以指示确定的功率值。此时，功率控制信息可以直接携带该功率值，即绝对功率值，如1毫瓦；或者，功率控制信息可以为相对值，即与某个确定的基准功率的差值，这种情况下，需要根据该相对值和该基准功率得到功率的绝对值，如基准功率为1毫瓦，功率控制信息用相对值表示为-3dB，则功率控制信息实际指示的用于上行传输的功率值为0.5毫瓦。
可选地，在本发明实施例中，竞争传输单元的功率控制信息可以指示功率范围。此时，该功率范围可以是连续的功率范围，该功率控制信息中可以携带该功率范围的上限值和/或下限值；或者，该功率范围可以是离散的功率 范围，即包括多个功率数值；或者其他的形式。
可选地，该码域资源包括稀疏码分多址SCMA码本、低密度签名LDS组或码分多址CDMA码组。
具体地说，在本发明实施例中，可以采用SCMA码本、LDS组或CDMA码组作为码域资源，应理解，以上列举的作为码域资源的具体实例仅为实例性说明，本发明并不限定于此，其他能够用于传输的码本均落入本发明的保护范围内。
可选地，该SCMA码本包括至少两个码字，码本由两个或两个以上的码字组成，码本中的码字可以互不相同。码本可以表示一定长度的数据的可能的数据组合与码本中码字的映射关系,映射关系可以是直接的映射关系。码字可以表示为多维复数向量，其维数为两维或两维以上，用于表示数据与两个或两个以上调制符号之间的映射关系，该调制符号包括至少一个零调制符号和至少一个非零调制符号，数据可以为二进制比特数据或者多元数据。
可选地，该LDS组包括至少两个签名序列，该LDS组用于指示至少两种数据组合与该至少两个签名序列的映射关系，该签名序列为多维复数向量，该多维向量包括至少一个零元素和至少一个非零元素，该签名序列用于对调制符号进行幅度和相位的调整，该调制符号是通过调制星座对数据进行星座映射后得到的。
具体地说，低密度签名(LDS，Low Density Signature)技术也是一种非正交多址接入和传输技术，当然该LDS技术在通信领域还可以被称为其他名称。该类技术将来自一个或多个用户的O(O为不小于1的整数)个数据流叠加到P(P为不小于1的整数)个子载波上进行发送，其中每个数据流的每个数据都通过稀疏扩频的方式扩展到P个子载波上。当O的取值大于P时，该类技术可以有效地提升网络容量，包括系统可接入用户数和频谱效率等。因此，LDS技术作为一种重要的非正交接入技术，已经引起越来越多的关注，并成为未来无线蜂窝网络演进的重要备选接入技术。
可选地，在本发明实施例中，除了功率控制信息，竞争传输单元的配置信息还可以包括但不限于以下一种或几种的组合：时域资源信息，如无线帧编号、子帧编号、符号编号等；频域资源信息，如子载波编号、资源块编号等；空域资源信息，如发送天线编号、波束编号等；上行导频资源信息；码本资源信息，如SCMA码本、LDS组、CDMA码组等；调制编码信息，如 传输块大小、码率、调制阶数等。
在本发明实施例中，竞争传输单元还可以包括导频资源，码域资源和导频资源可以组成码域资源-导频组合，其中，不同的码域资源-导频组合中的码域资源可以相同或不同，以及不同的码域资源-导频组合中的导频互不相同，不同码域资源-导频组合中的导频相互正交。
可选地，在本发明实施例中，可以使用广播信道，如长期演进LTE系统中的广播控制信道BCCH(Broadcast Control CHannel)，以广播的方式向系统中的全部或部分终端下发竞争传输单元的配置信息，如携带在广播消息、系统信息中下发等；也可以使用专用控制信道，如长期演进LTE系统中的DCCH(Dedicated Control CHannel)，以单播的方式向特定的一个或一组用户下发竞争传输单元指示信息，如携带在无线资源控制连接重配置(RRCConnectionReconfiguration)指令中下发等；也可以使用其他信道，以其他方式向系统中的全部终端，或部分终端，或特定的一个终端或一组终端下发竞争传输单元指示信息。
可选地，在本发明实施例中，该第一竞争传输单元的配置信息包括的功率控制信息为重配置的功率控制信息，即基站可以根据实际情况实时重配第一竞争传输单元对应的功率控制信息。

可选地，上述第一资源即可以用于非授权传输，例如，用于第一竞争传输单元和第二竞争传输单元的传输，也可以同时用于非授权传输和授权传输，例如用于第一竞争传输单元的传输和授权传输。
可选地，所述确定第一竞争传输单元的配置信息，包括：
按照以下原则中的至少一种确定所述第一竞争传输单元的配置信息：
所述第一竞争传输单元的功率控制信息对应的功率水平与使用所述第一竞争传输单元进行上行传输的终端与基站之间的上行信道质量负相关；
所述第一竞争传输单元的功率控制信息对应的功率水平与使用所述第三竞争传输单元进行上行传输的终端与基站之间的上行信道质量正相关；
所述第一竞争传输单元的功率控制信息对应的功率水平与使用所述第一竞争传输单元进行上行传输的终端与基站的距离负相关；
所述第一竞争传输单元的功率控制信息对应的功率水平与使用所述第三竞争传输单元进行上行传输的终端与基站的距离负相关；
所述第一竞争传输单元的功率控制信息对应的功率水平与使用所述第一竞争传输单元进行上行传输的终端数量负相关；
所述第一竞争传输单元的功率控制信息对应的功率水平与使用第三竞争传输单元进行上行传输的终端数量正相关；
所述第一竞争传输单元的功率控制信息对应的功率水平与第一资源的邻区上行负载负相关；
所述第一竞争传输单元的功率控制信息对应的功率水平与所述第一竞争传输单元对应的小区在第一资源上受到的来自邻区的干扰正相关；以及
所述第一竞争传输单元的功率控制信息对应的功率水平与使用所述第一资源的非所述第一竞争传输单元对应的小区在第一资源上受到的来自邻区的干扰负相关。
为了便于理解，以下将结合几种举例对如何确定竞争传输单元的功率控制信息进行描述。
举例一，如图5所示，如果使用第一竞争传输单元进行非授权传输的终端或终端组与基站之间的上行信道质量好于使用第三竞争传输单元进行非 授权传输的终端或终端组与基站之间的上行信道质量，配置第一竞争传输单元的上行功率为第一上行功率，且配置第三竞争传输单元的上行功率为第二上行功率，其中，第一上行功率水平低于第二上行功率水平。通常来说，可以通过以下两种方式获知信道质量情况：基站可以测量上行信道，或者终端测量下行信道并反馈测量结果。
举例二，如果使用第一竞争传输单元进行非授权传输的终端与基站的距离小于使用第二竞争传输单元进行非授权传输的终端与基站的距离，配置第一竞争传输单元的上行功率为第一上行功率，且配置第二竞争传输单元的上行功率为第二上行功率，其中，第一上行功率水平低于第二上行功率水平。可选地，使用该竞争传输单元的终端与基站的距离可以为所有的终端与基站的距离之和或者使用该竞争传输单元的终端与基站的距离可以为所有的终端与基站的距离的平均值等。
举例三，如图6所示，如果使用第一竞争传输单元进行非授权传输的的终端数量大于或远大于使用第三竞争传输单元进行非授权传输的终端数量，则配置第一竞争传输单元的上行功率为第一上行功率，且配置第三竞争传输单元的上行功率为第二上行功率，其中，第一上行功率水平低于第二上行功率水平。
应理解，虽然在举例一、二和三中，具体如何配置第一竞争传输单元的功率控制信息，是与其他竞争传输单元对应的上行信道质量或终端数量作为参考的，但是本发明并不限于此。例如，在配置第一竞争传输单元的功率控制信息时，可以根据参考门限来设定；例如，如果上行信道质量大于某一阈值，则设定第一竞争传输单元的上行功率为该阈值对应的值。
举例四，如果从获取到的邻居基站的竞争传输单元配置信息中发现邻居基站配置的第二竞争传输单元与第一竞争传输单元在传输资源上有重叠(例如，时域资源、频域资源和空域资源有重叠)，则可以重配置第一竞争传输单元的第一上行功率，使得重配后的第一上行功率水平低于之前的上行功率水平。当然，在初始配置第一竞争传输单元的功率控制信息时，发现该第一竞争传输单元的传输资源与其他竞争传输单元有重叠，则降低第一竞争传输单元的上行功率。从而可以避免第一竞争传输单元的终端对第二竞争传输单元终端较大的干扰。应理解，虽然在该举例中，是根据邻居基站的竞争传输 单元的传输资源情况确定上行功率的，本发明也可以根据相同基站相邻小区的非授权区域的传输资源情况确定上行功率。
举例五，如果与第一竞争传输单元相同的第一资源上的上行负载处于较高水平，例如负载指示值高于某个预设的门限，则可以重配置第一竞争传输单元的第一上行功率，使得重配后的第一上行功率水平低于之前的上行功率水平。当然，在初始配置第一竞争传输单元的功率控制信息时，发现与第一竞争传输单元相同的第一资源上的上行负载处于较高水平时，则可以根据具体负载情况来设定该第一竞争传输单元的功率控制信息，即上行负载越高，上行功率越低。从而可以避免第一竞争传输单元的终端对使用该相同资源的其他造成终端较大的干扰。
举例六，如果相邻基站的小区的受到使用第一资源的其他小区的上行干扰处于较高水平，例如干扰指示值高于某个预设的门限，则可以重配置第一竞争传输单元的第一上行功率，使得重配后的第一上行功率水平低于之前的上行功率水平。当然，在初始配置第一竞争传输单元的功率控制信息时，发现相邻基站的上行干扰处于较高水平时，则可以根据邻居基站具体的干扰情况来设定该第一竞争传输单元的功率控制信息，即邻居基站上行干扰越高，上行功率越低。从而可以避免第一竞争传输单元的终端对邻居基站终端较大的干扰。
应理解，在本发明实施例中，在举例一、二和三中，第一上行功率水平低于第二上行功率水平，具体是指：如果上行功率控制信息是某个确定的功率，则第一功率低于第二功率；如果上行功率控制信息是功率上限，则第一功率上限低于第二功率上限；如果上行功率控制信息是功率下限，则第一功率下限低于第二功率下限；如果上行功率控制信息是离散或连续的功率范围，则第一功率范围的上限低于第二功率范围的上限，和/或第一功率范围的下限低于第二功率范围的下限。在举例四、五和六中，重配置后的第一上行功率水平低于重配置前的上行功率水平，具体是指：如果上行功率控制信息是某个确定的功率，则重配置后的第一上行功率低于重配置前的上行功率；如果上行功率控制信息是功率上限，则重配置后的第一上行功率上限低于重配置前的上行功率上限；如果上行功率控制信息是功率下限，则重配置后的第一上行功率下限低于重配置前的上行功率下限；如果上行功率控制信息是 离散或连续的功率范围，则重配置后的第一上行功率范围的上限低于重配置前的上行功率范围的上限，和/或重配置后的第一上行功率范围的下限低于重配置前的上行功率范围的下限。
还应理解，如何确定竞争传输单元的功率控制信息并不限于以上举例描述，本发明实施例还有其他的实现方式。例如，使用该第一竞争传输单元进行上行传输的终端与基站之间的上行信道质量、使用该第一竞争传输单元进行上行传输的终端数量，该第一竞争传输单元的传输资源与邻居基站的竞争传输单元的传输资源的重叠情况和邻居基站的上行负载信息、干扰强度信息中两种或两种以上因素综合考虑等。
因此，在本发明实施例中，根据使用该第一竞争传输单元进行上行传输的上行信道质量、使用该第一竞争传输单元进行上行传输的终端数量，该第一竞争传输单元的传输资源与邻居基站的竞争传输单元的传输资源的重叠情况和邻居基站的上行负载信息、上行干扰强度信息中的至少一种，确定第一竞争传输单元的功率控制信息，可以更进一步避免小区用户间干扰和邻区干扰。
可选地，在本发明实施例中，竞争传输单元的配置信息可以携带在SIB2中，由基站下发给终端，例如，如图7所示。
可选地，在本发明实施例中，竞争传输单元的配置信息可以携带在无线资源控制连接重配置指令中，由基站下发给终端，例如，如图8所示。
可选地，在本发明实施例中，竞争传输单元的配置信息的具体实现可以如下所示：
Figure PCTCN2015082018-appb-000001
其中，
GrantFreeTransAreaInfo表示一个竞争传输单元的配置信息，其中至少包 含上行功率控制信息，即powerControlInfo；
GrantFreeTransAreaList表示一个或多个GrantFreeTransAreaInfo的列表，maxGrantFreeTransArea表示竞争传输单元的最大数目；
powerControlInfo可以用于指示确定的某个功率值，或功率上限，或功率下限，或连续或离散的功率范围，可以采用BIT STRING或INTEGER或ENUMERARED等方式来指示其绝对值或相对值；
others表示除上行功率控制信息powerControlInfo之外的竞争传输单元的其他配置信息，可以包括但不限于：时域资源信息、和/或频域资源信息、和/或空域资源信息、和/或上行导频资源信息、和/或码域资源信息、和/或编码调制信息等，这些信息可以采用BIT STRING或INTEGER或ENUMERARED等方式来指示；
value为各信息的取值，可以采用BIT STRING或INTERGER或ENUMERATED或其他方式表示。
以下给出更具体的实现举例：当竞争传输单元的配置信息由时域资源信息、频域资源信息和上行功率控制信息(功率上限)组成时，一种可能的实现方式为：
Figure PCTCN2015082018-appb-000002
其中，maxGrantFreeTransArea表示竞争传输单元的最大数目；
timeDomainResource是指分配给相应竞争传输单元的时频资源；其中，相应竞争传输单元的周期为X子帧；一个比特代表一个子帧，例如，比特‘1’代表竞争传输单元位于相应的子帧；
frequencyDomainResource是指非配给相应竞争传输单元的频域资源；每 个比特代表一个资源块，例如，比特‘1’表示相应资源块分配给竞争传输单元；
powerUpperBound是指当使用非授权传输模式在相应的竞争传输单元上，发送上行数据时，在36.xxx中限定的功率上限，该功率上限限定终端的最大传输功率。
上述给出了具体的竞争传输单元的配置信息的实现方式，当竞争传输单元的配置信息包含除上述资源外的其他资源信息，或者上行功率控制信息表示确定的功率值或功率下限或连续或离散的功率范围时，可以很容易参照上述具体示例给出竞争传输单元的配置信息。
因此，由于在竞争传输单元的配置信息中携带针对该竞争传输单元的功率控制信息，终端可以根据配置信息中的功率控制信息，确定使用该竞争传输单元进行上行传输时的功率，从而可以实现上行传输功率的可控，并且可以进一步通过控制上行传输的功率，来实现减少小区用户间干扰和邻区干扰。

因此，由于在竞争传输单元的配置信息中携带针对该竞争传输单元的功率控制信息，终端可以根据配置信息中的功率控制信息，确定使用该竞争传输单元进行上行传输时的功率，从而可以实现上行传输功率的可控，并且可以进一步通过控制上行传输的功率，来实现减少小区用户间干扰和邻区干扰。
