Description

一种用户设备和接入设备
本申请要求于2017年11月17日提交中国国家知识产权局、申请号为201711148365.9、发明名称为“一种用户设备和接入设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明实施例涉及信道测量技术，尤其涉及一种用户设备和接入设备。
背景技术
无线通信的传输效果与信道环境密切相关，因此，选择与信道环境相适配的传输参数对于无线通信而言至观重要。举例来说，在信道环境较好时，可以选用较为激进的调制编码方式(Modulation and Coding Scheme，MCS)，以提高传输吞吐量；在信道环境较差时，可以选用较为保守的MCS，以提高传输鲁棒性。
一般来说，可以借助信道测量来确定信道环境。以下行信道测量为例，用户设备(例如但不限于智能手机等)接收接入设备(例如但不限于基站等)发出的下行参考信号，据此确定下行信道环境并告知接入设备，以便接入设备选择合适的传输参数。
信道测量的结果通常可以通过信道状态信息(Channel State Information，CSI)来表示。举例来说，CSI可以包括，例如但不限于，以下信息之中的一种或者几种：信道质量指示(Channel Quality Indicator，CQI)、预编码矩阵指示(Precoding Matrix Indicator，PMI)、预编码类型指示(Precoding Type Indicator，PTI)、CSI参考信号资源指示(CSI-RS Resource Indicator，CRI)、秩指示(Rank Indication，RI)和其他信息等。
通常来说，信道测量需要根据特定的测量机制来进行，测量机制不同，测量过程和测量结果通常不同。最新研究进展表明，下一代无线通信系统将引入一种称为半静态测量的测量机制。半静态测量以预编码资源块组(Precoding Resource block Group，PRG)为基本单位来计算CSI上报频带(CSI reporting band)的CQI，因此PRG大小(PRG size)对于半静态测量至关重要。为使得PRG大小可以根据具体需要进行灵活变更，可以通过配置的方式来指示PRG大小。
然而，不难理解，通过专用配置信令来配置PRG大小必然引入信令开销，从而影响传输效率。因此，尚缺少一种机制，可以降低配置PRG大小所带来的信令开销。
发明内容
有鉴于此，实有必要提供一种用户设备，有助于降低配置PRG大小所带来的信令开销。
同时，提供一种接入设备，有助于降低配置PRG大小所带来的信令开销。
同时，提供一种接入设备，有助于降低配置PRG大小所带来的信令开销。
根据本发明实施例的第一方面，提供一种用户设备，包括：

收发器，用于发送所述配置信息。
在具体实现过程中，处理器可用于进行，例如但不限于，基带相关处理，收发器可以用于进行，例如但不限于，射频收发。上述器件可以分别设置在彼此独立的芯片上，也可以至少部分的或者全部的设置在同一块芯片上，例如，收发器可以设置在收发器芯片上。又例如，处理器可以进一步划分为模拟基带处理器和数字基带处理器，其中模拟基带处理器可以与收发器集成在同一块芯片上，数字基带处理器可以设置在独立的芯片上。随着集成电路技术的不断发展，可以在同一块芯片上集成的器件越来越多，例如，数字基带处理器可以与多种应用处理器(例如但不限于图形处理器，多媒体处理器等)集成在同一块芯片之上。这样的芯片可以称为系统芯片(System on Chip)。将各个器件独立设置在不同的芯片上，还是整合设置在一个或者多个芯片上，往往取决于产品设计的具体需要。本发明实施例对上述器件的具体实现形式不做限定。
根据本发明实施例的第七方面，提供一种配置方法，包括：
接收配置信息，所述配置信息用于配置至少一个PRB绑定大小。
基于所述至少一个PRB绑定大小确定PRG大小。
根据本发明实施例的第八方面，提供一种配置方法，包括：
生成配置信息，所述配置信息用于配置多个PRB绑定大小，其中，在所述多个PRB绑定大小之中，排列位置为预设位置的PRB绑定大小用作PRG大小。

根据本发明实施例的第十方面，提供一种处理器，用于执行上述各种方法。在执行这些方法的过程中，上述方法中有关发送配置信息和接收配置信息的过程，可以理解为由处理器输出配置信息的过程，以及处理器接收输入的配置信息过程。具体来说，在输出配置信息时，处理器将该配置信息输出给收发器，以便由收发器进行发射。更进一步的，该配置信息在由处理器输出之后，还可能需要进行其他的处理，然后才到达收发器。类似的，处理器接收输入的配置信息时，收发器接收该配置信息，并将其输入处理器。更进一步的， 在收发器收到该配置信息之后，该配置信息可能需要进行其他的处理，然后才输入处理器。
基于上述原理，举例来说，前述方法中提及的接收配置信息可以理解为处理器接收输入的配置信息。又例如，发送配置信息可以理解为处理器输出配置信息。
如此一来，对于处理器所涉及的发射、发送和接收等操作，如果没有特殊说明，或者，如果未与其在相关描述中的实际作用或者内在逻辑相抵触，则均可以更加一般性的理解为处理器输出和接收输入等操作，而不是直接由射频电路和天线所进行的发射、发送和接收操作。
在具体实现过程中，上述处理器可以是专门用于执行这些方法的处理器，也可以是执行存储器中的计算机指令来执行这些方法的处理器，例如通用处理器，此时，处理器和存储器归属于一通信设备，例如包含在该通信设备中。上述存储器可以为非瞬时性(non-transitory)存储器，例如只读存储器(Read Only Memory，ROM)，其可以与处理器集成在同一块芯片上，也可以分别设置在不同的芯片上，本发明实施例对存储器的类型以及存储器与处理器的设置方式不做限定。

具体实施方式
目前正处于研发阶段的下一代无线通信系统又可称为新无线(New Radio，NR)系统或者5G系统。最新研究进展显示，在下一代无线通信系统中，测量机制至少包括半开环(Semi-open loop)测量和闭环(Close loop)测量，其中，半开环测量又可称为半开环反馈(Semi-open loop feedback)，闭环测量又可称为闭环反馈(Close loop feedback)。
半开环测量可以用于对CSI上报频带进行信道测量。CSI上报频带可以理解为一种需要进行CSI上报的频带。进一步的，CSI上报频带可以包含多个子带(Subband)，这些子带可以是相互连续的，也可以是相互不连续的，还可以至少一部分子带是连续的，本发明实施例对这些子带的连续性不做限定。更进一步的，这些子带可以同属于同一个特定频带，该特定频带可以根据需要进行设定，本发明实施例对于该特定频带不做限定。举例来说，上述特定频带可以是带宽部分(Bandwidth part)。带宽部分可以理解为一段连续的频带，该频带包含至少一个连续的子带，每个带宽部分可以对应一组系统参数(numerology)，包括例如但不限于，子载波间隔(Subcarrier spacing)和循环前缀(Cyclic Prefix，CP)等，不同带宽部分可以对应不同的系统参数。作为可选的，在同一个传输时间间隔(Transmission Time Interval，TTI)内，在多个带宽部分之中，可以仅有一个带宽部分可用，其他带宽部分不可用。除上述特征外，在具体实现过程中，还可以对CSI上报频带的定义添加进一步的限定。
在对CSI上报频带进行半开环测量时，反馈的CSI可以包括整个CSI上报频带的CSI。这里所说的整个CSI上报频带的CSI，也可以称为CSI上报频带的宽带CSI，这种CSI是指将CSI上报频带作为一个整体而计算得到的CSI，而不是对CSI上报频带的各个部分(例如但不限于各个子带)分别进行半开环测量而获得的各个部分的CSI的集合。举例来说，整个CSI上报频带的CQI可以采用，例如但不限于，如下方式进行计算。对于CSI上报频带所包含的每个PRG，在码本中随机选择一个预编码矩阵，其中，上述码本可以是码本子集限制(Codebook Subset Restriction)信令所指示的码本，该码本通常是基于信道统计信息确定的，因此在一定程度上可以适配信道环境的变化趋势。将该PRG对应的信道矩阵与该预编码矩阵相乘，获得该PRG的等效信道矩阵，并确定该等效信道矩阵的信号干扰噪声比(Signal to Interference plus Noise Ratio，SINR)。计算CSI上报频带所包含所有PRG的SINR的平均值或者可以反映CSI上报频带整体SINR的其他值，并根据该值确定对应的CQI，作为整个CSI上报频带的CQI。
闭环测量可以用于对CSI上报频带、子带或者子带组等进行信道测量。例如，在对子带在进行闭环测量时，可基于信道容量最大化或者吞吐量最大化等原则，从码本中选择预编码矩阵，并通过PMI上报该预编码矩阵。同时，还可以将子带的信道矩阵和上述预编码矩阵相乘，获得该子带的等效信道矩阵。在算得该等效信道矩阵的SINR之后，便可根据该SINR确定对应的CQI。在计算子带组的CQI时，也可以参考半静态测量时采用的计算SINR平均值的方法，获得子带组对应的CQI。本领域的技术人员应该明白，在具体实现过程中，上述CQI还可以采用其他方法进行计算，本发明实施例对具体计算方法不做限制。
信道测量过程发生在数据传输之前，因此在进行数据传输时，信道测量过程中确定的CSI可能会发生改变。在低速场景下，信道环境变化不快，因此在进行数据传输时，之前在信道测量过程中确定的CSI发生的变化通常不会很大。在这种情况下，由于闭环测量 中确定的CSI是基于信道环境确定的，该CSI与信道环境更加契合，因此数据传输效果更好。然而，在高速场景下，信道环境变化很快，在进行数据传输时，之前在信道测量过程中确定的CSI很可能发生较大的变化，由此导致之前测量获得的CSI过时，从而无法与信道环境相匹配。在这种情况下，半开环测量所确定的CSI往往能够取得更加良好的效果。如上文所述，半开环测量涉及的预编码矩阵选自特定的码本，该码本是基于信道统计信息确定的，在一定程度上可以适配信道环境的变化趋势。因此，即使随机选择，也与信道环境存在一定程度的匹配。另一方面，半开环测量所确定的CQI是以PRG为单位基于随机选择的多个预编码矩阵确定的，在一定程度上引入了分集传输的效果，因此传输效果更加鲁棒。
在进行下行信道测量时，上述计算CSI的过程通常由用户设备执行。用户设备确定CSI，并将其上报给接入设备。
有关半开环测量和闭环测量的更进一步的细节可以参考现有技术，例如但不限于下一代无线通信系统相关技术标准和提案。随着研究的深入进行，在下一代无线通信系统中，半开环测量和闭环测量的操作细节也有可能发生变化，然而，本领域的技术人员在了解本发明实施例提供的技术方案之后应当明白，本发明实施例提供的技术方案也适用于变化后的半开环测量和闭环测量。
由上文描述可知，在半开环测量在计算CQI的过程中需要以PRG为基本单位计算SINR，因此PRG大小对于半开环测量而言至关重要。，PRG大小通常可以理解为PRG的频带宽度，一般来说，PRG包含多个资源块(Resource Block，RB)，因此PRG大小可以具体为PRG所包含RB的数量。为使得PRG大小可以根据具体需要进行灵活变更，可以通过配置的方式来指示PRG大小。然而，不难理解，配置PRG大小必然引入信令开销，从而影响传输效率。
预编码技术是MIMO技术的核心技术之一，该技术借助与信道属性相匹配的预编码矩阵来对待发射信号进行处理，使得经过预编码的待发射信号与信道相适配，因此传输过程得到优化，接收信号质量(例如SINR)得以提升。目前，预编码技术已经被多种无线通信标准采纳，例如但不限于长期演进(Long Term Evolution，LTE)。
在对数据传输进行预编码的过程中，通常需要确定基于同一预编码矩阵进行预编码的频带的宽度，该频带宽度通常通过物理资源块绑定大小(PRB(Physical RB)bundling size)来指示。相比而言，如上文所述，在基于半静态测量计算CQI时，每个随机选择的预编码矩阵用于对一个PRG进行预编码，因此该随机选择的预编码矩阵所适用频带的宽度是该PRG的频带宽度，即PRG大小。由此可见，半静态测量过程中涉及的PRG大小与在对数据传输进行预编码过程中涉及的PRB绑定大小存在相似之处。因此，可以尝试将PRG大小设置成与PRB绑定大小相等。如此一来，便可以通过指示PRB绑定大小来指示与信道测量相关联的PRG大小，降低配置PRG大小而引入的信令开销。
最新研究进展显示，在下一代无线通信系统中，接入设备会通过配置信令为用户设备事先配置多个PRB绑定大小，而预编码过程中具体使用的PRB绑定大小，则是由接入设备从上述多个PRB绑定大小之中选择并指示给用户设备的。具体来说，在配置过程中，接入设备通过无线资源控制(Radio Resource Control，RRC)信令或者其他信令为用户设备配置多个PRB绑定大小，在预编码过程中，接入设备通过下行控制信息(Downlink Control Information，DCI)或者其他信令具体指示预编码过程中具体使用的PRB绑定大小。由此可见，下一代无线通信系统将采用配置+指示的方式来通知PRB绑定大小，其中配置过程用于配置多个PRB绑定大小，指示过程用于在配置的多个PRB绑定大小中指示预编码过程中采用的PRB绑定大小。应注意，上述通知PRB绑定大小的方式可以不是唯一的，在下一代无线通信标准中，也可以定义通知PRB绑定大小的其他方式。举例来说，也可以在配置PRB绑定大小的过程中仅仅配置一个PRB绑定大小，在这种情况下，通知 PRB绑定大小的过程仅包含配置过程即可，而无需包含指示过程。
此外，在指示多个PRB绑定大小中在预编码过程中采用的PRB绑定大小时候，可以采用多种方式进行指示，例如但不限于，可以直接指示待指示信息，例如待指示信息本身或者该待指示信息的索引等；也可以通过指示其他信息来间接指示待指示信息，其中该其他信息与待指示信息之间存在关联关系；还可以仅仅指示待指示信息的一部分，而待指示信息的其他部分则是已知的或者提前约定的；此外，具体的指示方式还可以是上述指示方法的各种组合等。在具体实现过程中，可以根据具体的需要选择所需的指示方式，本发明实施例对选择的指示方式不做限定，如此一来，本发明实施例涉及的指示方式应理解为涵盖可以使得待指示方获知待指示信息的各种方法。同时，待指示信息可以做为一个整体一起发送，也可以分成多个子信息分开发送，而且这些子信息的发送周期和/或发送时机可以相同，也可以不同。具体发送方法可以参考现有技术，本发明对此不做限定。
更进一步的，最新研究进展显示，在下一代无线通信系统中，建议通过RRC信令或者其他信令来指示PRG大小。换句话说，将不会采用类似于通知PRB绑定大小过程中采用的配置+指示的方式通知PRG大小。因此，可以将PRG大小设置成与通过RRC信令或者其他信令配置的PRB绑定大小相同，如此一来便可以通过配置PRB绑定大小来指示与信道测量相关联的PRG大小。
然而，如上文所述，在通过RRC信令或者其他信令配置PRB绑定大小的过程中，配置的PRB绑定大小往往有多个。在这种情况下，将多个PRB绑定大小之中的哪一个PRB绑定大小作为PRG大小，便成了亟待解决的问题。
上述问题的一种解决方案，是将通过RRC信令或者其他信令配置的PRB绑定大小强制设置成一个，然而这样必然导致PRB绑定大小不够灵活。
本发明实施例提供了一种技术方案，可以基于预设的指示规则，根据配置的多个PRB绑定大小确定确定PRG大小。下面就结合附图和具体实施例来对本发明实施例提供的技术方案进行详细描述。
图1是依照本发明一实施例的无线通信网络100的示范性示意图。如图1所示，无线通信网络100包括基站102～106和终端设备108～122，其中，基站102～106彼此之间可通过回程(backhaul)链路(如基站102～106彼此之间的直线所示)进行通信，该回程链路可以是有线回程链路(例如光纤、铜缆)，也可以是无线回程链路(例如微波)。终端设备108～122可通过无线链路(如基站102～106与终端设备108～122之间的折线所示)与对应的基站102～106通信。
基站102～106通常作为接入设备来为通常作为用户设备的终端设备108～122提供无线接入服务。具体来说，每个基站都对应一个服务覆盖区域(又可称为蜂窝，如图1中各椭圆区域所示)，进入该区域的终端设备可通过无线信号与基站通信，以此来接受基站提供的无线接入服务。基站的服务覆盖区域之间可能存在交叠，处于交叠区域内的终端设备可收到来自多个基站的无线信号，因此这些基站可以进行相互协同，以此来为该终端设备提供服务。例如，多个基站可以采用多点协作(Coordinated multipoint，CoMP)技术为处于上述交叠区域的终端设备提供服务。例如，如图1所示，基站102与基站104的服务覆盖区域存在交叠，终端设备112便处于该交叠区域之内，因此终端设备112可以收到来自基站102和基站104的无线信号，基站102和基站104可以进行相互协同，来为终端设备112提供服务。又例如，如图1所示，基站102、基站104和基站106的服务覆盖区域存在一个共同的交叠区域，终端设备120便处于该交叠区域之内，因此终端设备120可以收到来自基站102、104和106的无线信号，基站102、104和106可以进行相互协同，来为终端设备120提供服务。
依赖于所使用的无线通信技术，基站又可称为节点B(NodeB)，演进节点B(evolved NodeB,eNodeB)以及接入点(Access Point，AP)等。此外，根据所提供的服务覆盖区 域的大小，基站又可分为用于提供宏蜂窝(Macro cell)的宏基站、用于提供微蜂窝(Pico cell)的微基站和用于提供毫微微蜂窝(Femto cell)的毫微微基站等。随着无线通信技术的不断演进，未来的基站也可以采用其他的名称。
终端设备108～122可以是具备无线通信功能的各种无线通信设备，例如但不限于移动蜂窝电话、无绳电话、个人数字助理(Personal Digital Assistant，PDA)、智能电话、笔记本电脑、平板电脑、无线数据卡、无线调制解调器(Modulator demodulator，Modem)或者可穿戴设备如智能手表等。随着物联网(Internet of Things，IOT)技术和车联网(Vehicle-to-everything，V2X)技术的兴起，越来越多之前不具备通信功能的设备，例如但不限于，家用电器、交通工具、工具设备、服务设备和服务设施，开始通过配置无线通信单元来获得无线通信功能，从而可以接入无线通信网络，接受远程控制。此类设备因配置有无线通信单元而具备无线通信功能，因此也属于无线通信设备的范畴。此外，终端设备108～122还可以称为移动台、移动设备、移动终端、无线终端、手持设备、客户端等。
基站102～106，和终端设备108～122均可配置有多根天线，以支持MIMO(多入多出，Multiple Input Multiple Output)技术。进一步的说，基站102～106和终端设备108～122既可以支持单用户MIMO(Single-User MIMO，SU-MIMO)技术，也可以支持多用户MIMO(Multi-User MIMO，MU-MIMO)，其中MU-MIMO可以基于空分多址(Space Division Multiple Access，SDMA)技术来实现。由于配置有多根天线，基站102～106和终端设备108～122还可灵活支持单入单出(Single Input Single Output，SISO)技术、单入多出(Single Input Multiple Output，SIMO)和多入单出(Multiple Input Single Output，MISO)技术，以实现各种分集(例如但不限于发射分集和接收分集)和复用技术，其中分集技术可以包括例如但不限于发射分集(Transmit Diversity，TD)技术和接收分集(Receive Diversity，RD)技术，复用技术可以是空间复用(Spatial Multiplexing)技术。而且上述各种技术还可以包括多种实现方案，例如发射分集技术可以包括，空时发射分集(Space-Time Transmit Diversity，STTD)、空频发射分集(Space-Frequency Transmit Diversity，SFTD)、时间切换发射分集(Time Switched Transmit Diversity，TSTD)、频率切换发射分集(Frequency Switch Transmit Diversity，FSTD)、正交发射分集(Orthogonal Transmit Diversity，OTD)、循环延迟分集(Cyclic Delay Diversity，CDD)等分集方式，以及上述各种分集方式经过衍生、演进以及组合后获得的分集方式。例如，目前LTE(长期演进，Long Term Evolution)标准便采用了空时块编码(Space Time Block Coding，STBC)、空频块编码(Space Frequency Block Coding，SFBC)和CDD等发射分集方式。上文以举例的方式对发射分集进行了的概括性的描述。本领域技术人员应当明白，除上述实例外，发射分集还包括其他多种实现方式。因此，上述介绍不应理解为对本发明技术方案的限制，本发明技术方案应理解为适用于各种可能的发射分集方案。
此外，基站102～106和终端设备108～122可采用各种无线通信技术进行通信，例如但不限于，时分多址(Time Division Multiple Access，TDMA)技术、频分多址(Frequency Division Multiple Access，FDMA)技术、码分多址(Code Division Multiple Access，CDMA)技术、时分同步码分多址(Time Division-Synchronous Code Division Multiple Access，TD-SCDMA)、正交频分多址(Orthogonal FDMA，OFDMA)技术、单载波频分多址(Single Carrier FDMA，SC-FDMA)技术、空分多址(Space Division Multiple Access，SDMA)技术以及这些技术的演进及衍生技术等。上述无线通信技术作为无线接入技术(Radio Access Technology，RAT)被众多无线通信标准所采纳，从而构建出了在今天广为人们所熟知的各种无线通信系统(或者网络)，包括但不限于全球移动通信系统(Global System for Mobile Communications，GSM)、CDMA2000、宽带CDMA(Wideband CDMA，WCDMA)、由802.11系列标准定义的WiFi、全球互通微波存取(Worldwide Interoperability for Microwave Access，WiMAX)、长期演进(Long Term Evolution，LTE)、LTE升级版 (LTE-Advanced，LTE-A)以及这些无线通信系统的演进系统等。如无特别说明，本发明实施例提供的技术方案可应用于上述各种无线通信技术和无线通信系统。此外，术语“系统”和“网络”可以相互替换。
应注意，图1所示的无线通信网络100仅用于举例，并非用于限制本发明的技术方案。本领域的技术人员应当明白，在具体实现过程中，无线通信网络100还可能包括其他设备，同时也可根据具体需要来配置基站和终端设备的数量。
图2是依照本发明一实施例的用户设备200的示范性逻辑结构示意图。如图2所示，用户设备200包括收发模块202和处理模块204。
收发模块202用于接收配置信息，所述配置信息用于配置至少一个PRB绑定大小。
处理模块204用于基于所述至少一个PRB绑定大小确定PRG大小。
具体来说，该PRG大小为与信道测量相关联的PRG大小，该PRG大小可以与数据传输过程中的PRG大小相同或者不同，其中，上述数据传输可以是，例如但不限于，通过物理下行共享信道(Physical Downlink Shared Channel，PDSCH)所进行的数据传输。
本发明实施例提供的技术方案通过配置PRB绑定大小来配置PRG大小，这样一来便无需为配置PRG大小设置专用的信令，因此有助于降低配置PRG大小而引入的信令开销。
在具体实现过程中，所述配置信息来自接入设备，该配置信息可以通过例如但不限于如下信令其中之一进行发送：
物理层信令；
媒体访问控制层信令；
无线资源控制信令。
物理层信令也称为第一层(Layer 1，L1)信令，其通常可以由物理层帧中的控制部分来承载。L1信令的典型例子是LTE标准中定义的物理下行控制信道(Physical Downlink Control Channel，PDCCH)中承载的DCI和物理上行控制信道(Physical Uplink Control Channel，PUCCH)中承载的上行控制信息(Uplink Control Information，UCI)。在一些情况下，L1信令也可以由物理层帧中的数据部分来承载，例如，UCI有时也可以通过物理上行共享信道(Physical Uplink Shared Channel，PUSCH)来承载。不难看出，L1信令的发送周期或者信令周期通常为物理层帧的周期，因此这种信令通常用于实现一些动态的控制，以传递一些变化频繁的信息，例如，可以通过物理层信令传送资源分配信息。
媒体访问控制(Media Access Control，MAC)层信令属于第二层(Layer 2)信令，其通常可以由，例如但不限于，第二层帧的帧头来承载。上述帧头中还可能携带，例如但不限于，源地址和目的地址等信息。除帧头外，第二层帧通常还包含帧体。在一些情况下，L2信令也可以由第二层帧的帧体来承载。第二层信令的典型例子是802.11系列标准中MAC帧的帧头中的帧控制(Frame Control)字段中携带的信令，或者一些协议中定义的MAC控制实体(Control Entity，MAC-CE)。第二层帧通常可以携带在物理层帧的数据部分。上述配置信息也可以通过媒体访问控制层信令之外的其他第二层信令发送。
RRC信令属于第三层(Layer 3)信令，其通常是一些控制消息，L3信令通常可以携带在第二层帧的帧体中。L3信令的发送周期或者控制周期通常较长，适用于发送一些不会频繁发生变化的信息，例如，在现有的一些通信标准中，L3信令通常用于承载一些配置信息。上述配置信息也可以通过RRC信令之外的其他第三层信令发送。
上文所述仅为物理层信令、MAC层信令、RRC信令、第一层信令、第二层信令和第三层信令的原理性描述，有关三种信令的具体细节可以参考现有技术，因此本文不再赘述。
在具体实现过程中，可以优先通过第三层信令，例如但不限于RRC信令，来传送配置信息，这是因为通过配置信息来配置的多个PRB绑定大小通常不会频繁变化。
有关PRB绑定大小的相关技术内容可以参考现有技术，本发明实施例对此不再赘述。
上述至少一个PRB绑定大小可以仅包含一个PRB绑定大小，在这种情况下，处理模 块204可以将该PRB绑定大小用作PRG大小。如上文所述，可以将通过RRC信令或者其他信令配置的PRB绑定大小强制设置成一个，在这种情况下，设置的PRB绑定大小便用作PRG大小。然而，如上文所述，这种方法这样必然导致PRB绑定大小不够灵活。
上述至少一个PRB绑定大小也可以包含多个PRB绑定大小，在这种情况下，PRG大小为多个PRB绑定大小之中由预设指示规则所指示的PRB绑定大小。具体来说，所述指示规则可以为，例如但不限于，下列规则之中的一种或者几种的组合。
规则1，将多个PRB绑定大小之中的最大值用作PRG大小。
规则2，将多个PRB绑定大小之中的最小值用作PRG大小。
规则3，将多个PRB绑定大小之中排列位置为预设位置的PRB绑定大小用作PRG大小。更进一步的，例如，可以将上述预设位置设置为第一个位置或者最后一个位置。
通常来说，当配置信息包含多个PRB绑定大小时，这些PRB绑定大小通常按照一定的顺序排列在配置信息内。如此一来，便可以按照上述规则3来确定用作PRG大小的PRB绑定大小。
在另一种实现方案中，所述配置信息进一步包含指示信息，所述指示信息用于指示所述多个PRB绑定大小之中用作PRG大小的PRB绑定大小。具体来说，该指示信息可以指示PRB绑定大小的索引，或者，该指示信息也可以指示如何在上述多个PRB绑定大小之中选择用作PRG大小的PRB绑定大小。例如，所述指示信息可以指示上述一种规则或者几种规则的组合。
以下以具体实例来对上述规则和方案进行详细描述。
假设配置信息所包含的具体信息如下列表1所示：
索引 PRB绑定大小
1 2
2 4
3 8
表1
由表1可知，配置信息包含顺序排列的3个PRB绑定大小，分别为2、4和8，其索引分别为1、2和3。当上述指示规则为规则1时，则确定的PRG大小为8。当上述指示规则为规则2时，则确定的PRG大小为2。当上述指示规则为规则3且上述规则3中的预设位置为位置1时，则确定的PRG大小为2。
又例如，配置信息中的指示信息进一步指示PRG大小为排列位置为2的PRB绑定大小，即4。又例如，该指示信息进一步指示PRG大小为索引为3的PRB绑定大小，即8。
图3是依照本发明一实施例的接入设备300的示范性逻辑结构示意图。如图3所示，接入设备300包括处理模块302和收发模块304。
处理模块302用于生成配置信息，所述配置信息用于配置多个PRB绑定大小，其中，在所述多个PRB绑定大小之中，排列位置为预设位置的PRB绑定大小用作PRG大小。
收发模块304用于发送所述配置信息。
具体来说，该配置信息发往用户设备。
如上文所述，配置信息可以用于配置多个PRB绑定大小，在这种情况下，PRG大小为多个PRB绑定大小之中由预设指示规则所指示的PRB绑定大小。更进一步的，该预设指示规则可以是将配置信息所配置的多个PRB绑定大小之中排列位置为预设位置的PRB绑定大小用作PRG大小。在具体实现过程中，可以将上述预设位置设置为第一个位置或者最后一个位置。
在这种情况下，为便于用户设备根据上述预设规则在多个PRB绑定大小确定用作PRG大小的PRB绑定大小，在生成配置信息时，接入设备需要将用作PRG大小的PRB绑定大小排列在通过该配置信息配置的多个PRB绑定大小之中的预设位置。
接入设备300所涉及的各种技术细节已经在上文结合用户设备200进行了详细的描述，因此此处不再赘述。
图4是依照本发明一实施例的接入设备400的示范性逻辑结构示意图。如图4所示，接入设备400包括处理模块402和收发模块404。
处理模块402用于生成配置信息，所述配置信息用于配置多个PRB绑定大小，该配置信息包含指示信息，该指示信息用于指示多个PRG绑定大小之中用作PRG大小的PRB绑定大小。
收发模块404用于发送所述配置信息。
具体来说，该配置信息发往用户设备。
接入设备400所涉及的各种技术细节已经在上文结合用户设备200进行了详细的描述，因此此处不再赘述。

步骤704，发送所述配置信息。
