Description

一种无线通信方法、 基站及用户设备
本申请要求于 2012 年 5 月 31 日提交中国专利局、 申请号为 201210176604.2、 发明名称为"一种无线通信方法、 基站及用户设备"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
本发明涉及通信技术领域，特别涉及无线通信方法、基站及用户设备。。 背景技术
在现有的频分双工或时分双工的无线通信***中， 在相同的无线资源 上， 用户设备（User Equipment, UE )与基站之间的通信只能进行数据的单 向传输， 即基站只能接收用户设备发送的上行数据， 或只能向用户设备发 送下行数据。
但是由于无线频谱资源非常稀缺和昂贵， 为了提高频语资源的利用率， 现在提出了一种全双工通信技术， 主要通过采用一定的技术手段， 例如在 通信设备上通过合适的天线布放来使得来自多根发射天线的信号在接收天 线处正好相互抵消， 或者利用在接收电路中利用已知的发射电路发射的信 号来执行干扰消除等， 来降低通信设备同时收发信号时产生的干扰， 从而 使得通信设备能够实现在相同的无线资源上双向传输数据。 考虑到 UE的成 本、复杂度制约问题以及老版本 UE的后向兼容问题， 目前的全双工***中， 只在基站侧支持全双工通信技术， 而在 UE侧可以不支持该技术， 这样， 在 相同资源上， 不同的 UE可以处于不同的状态 （接收或发送状态）。
但是现有的全双工***中， 对于 UE来说， 当在接收下行数据时， 也会 接收到来自其他 UE发送的上行数据， 干扰了下行数据的接收质量。 发明内容 本发明实施例提供无线通信方法、 基站及用户设备， 降低了在目前的 全双工无线通信***中， 用户设备之间的干扰。 本发明实施例提供一种无线通信方法， 包括：
对基站服务范围内的用户设备进行分组；
为各个分组的用户设备配置无线资源图案， 其中， 为同一分组内的用 户设备配置的无线资源图案相同， 不同分组之间用户设备配置的无线资源 图案不同；
根据所述配置的无线资源图案， 选择在相同无线资源上分别处于不同 通信状态的多个用户设备进行通信。
本发明实施例提供一种无线通信方法， 包括：
获取基站为用户设备配置的无线资源图案的信息， 所述无线资源图案 和与所述用户设备在同一分组的用户设备的无线资源图案相同， 且与所述 用户设备不在同一分组的其它用户设备的无线资源图案不同；
根据所述无线资源图案的信息， 与所述基站进行无线通信。
本发明实施例提供一种基站， 包括：
分组单元， 用于对基站服务范围内的用户设备进行分组；
资源图案配置单元， 用于为各个分组的用户设备配置无线资源图案， 其中， 为同一分组内的用户设备配置的无线资源图案相同， 为不同分組之 间用户设备配置的无线资源图案不同；
通信单元， 用于根据所述资源图案配置单元配置的无线资源图案， 选 择在相同无线资源上分别处于不同通信状态的多个用户设备进行通信。
本发明实施例提供一种用户设备， 包括：
资源图案获取单元， 用于获取基站为用户设备配置的无线资源图案的 信息， 所述无线资源图案和与所述用户设备在同一分组的用户设备的无线 资源图案相同， 且与所述用户设备不在同一分组的其它用户设备的无线资 源图案不同；
无线通信单元， 用于根据所述无线资源图案的信息， 与所述基站进行 无线通信。
在本发明实施例中， 在基站支持全双工无线通信的***中， 基站需要 对其服务范围内的用户设备进行分組， 并为同一分组的用户设备配置相同 的无线资源图案， 为不同分组的用户设备配置不同的无线资源图案， 这样 在基站根据配置的无线资源图案， 选择在相同无线资源上通信状态不同的 多个用户设备进行通信过程中， 并不是每个用户设备都会接收到其它用户 设备发送的上行数据， 只有不同分组之间的用户设备才可能在相同无线资 源上分别具有不同的通信状态， 这样可以适当地降低目前全双工无线通信 ***中， 由于每个用户设备都会接收到其它用户设备的上行数据， 而导致 的用户设备之间的干扰。 附图说明 为了更清楚地说明本发明实施例或现有技术中的技术方案， 下面将对 实施例或现有技术描述中所需要使用的附图作简单地介绍， 显而易见地， 下面描述中的附图仅仅是本发明的一些实施例， 对于本领域普通技术人员 来讲， 在不付出创造性劳动性的前提下， 还可以根据这些附图获得其他的 附图。

图 3是本发明实施例提供的另一种无线通信方法的流程图；
图 4是本发明实施例提供的一种基站的结构示意图；

图 7是本发明实施例提供的另一种用户设备的结构示意图。 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， 所描述的实施例仅仅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 有作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。
本发明实施例提供一种无线通信方法， 用于在长期演进（Long Term Evolution, LTE )、 高级长期演进（ Long Term Evolution Advanced, LTE-A )、 第三代移动通信*** （ 3rd-Generation， 3G )、 以及全球微波互联接入 ( Worldwide Interoperability for Microwave Access , WiMAX )等无线通信系 统中， 基站侧可以支持全双工无线通信， 而 UE侧可以不支持全双工无线通 信的场景下进行的无线通信。 其中基站可以按照如下的步骤进行无线通信， 流程图如图 1所示， 包括：
步骤 101， 对基站服务范围内的用户设备进行分组。
基站在为其服务范围内的用户设备分配资源时， 可以先对用户设备进 行分组， 基站可以按照预置的策略进行分组， 比如根据用户设备对其他设 备产生的干扰的能力进行分组， 将产生干扰能力比较大的用户设备分到同 一个组， 从而尽量减小用户设备之间的干扰； 或对用户设备进行随机分组 等。 这里预置的策略可以是用户根据需要预置在基站中的， 其具体的内容 并不造成对本发明的限定。
在具体的实现过程中， 基站可以通过如下的几种方式对用户设备进行 分组：
( 1 )基站可以获取基站服务范围内用户设备的路损信息， 并将路损相 差小于预置的路损范围的用户设备分到同一个分组。 这里路损信息是指无 线信号在两个通信设备之间传输过程中的损耗， 在本实施方式中， 路损信 息可以用来衡量用户设备之间的千扰情况， 路损相近的用户设备之间的千 扰较大， 基站将路损相近的用户设备分到同一个分组中。 具体地， 基站可 以通过测量 UE的上行信号的信号强度或测量 UE反馈的信息的信号强度来 获取 UE的路损信息。 在本实施方式中， UE的上行信号包括探测参考信息 ( Sounding Reference Signal, SRS ) 的信号等， UE反馈的信息包括参考信 号接收功率（Reference Signal Received Power, RSRP )等。
在其它实施例中， 基站还可以通过获取其它参数来确定用户设备之间 的干扰情况， 且根据干扰情况对用户设备分组后， 使得不同分组之间的用 户设备的干扰较小。
( 2 )基站可以获取基站服务范围内用户设备的业务参数， 并将将业务 参数一致的用户设备分到同一个分组， 所述业务参数包括业务量和 /或业务 类型。 由于不同用户设备有不同的业务需求， 这样通过将业务参数不一致 的用户设备分到不同分组， 使得基站在为各个分组的用户设备分配资源时， 可以给业务参数不同的用户设备分配不同的资源， 考虑到了用户设备的业 务差异性。
比如： 基站可以为下行业务量大的分组中的用户设备配置较多下行无 线资源， 为上行业务量大的分组中的用户设备配置较多上行无线资源， 为 上下行业务量都较小的分组中的用户设备配置较多的空闲无线资源， 为上 下行业务波动大的分组中的用户设备配置较大的灵活无线资源。
( 3 )基站可以获取基站服务范围内用户设备所支持的复用（ Duplexing ) 技术和 /或多址接入 ( multiple access, MA )技术， 并将支持相同复用技术 和 /或多址接入技术的用户设备分到同一个分组。 其中复用技术包括频分双 工( frequency division duplex, FDD )和时分双工( time division duplex, TDD ); 而多址接入技术包括正交频分多址接入 ( Orthogonal Frequency Division Multiple Access, OFDMA )和单载波频分多址（ Single Carrier - Frequency Division Multiple Access, SC-FDMA )等。
可以理解， 基站还可以通过其他的方式对用户设备进行分组 , 比如对 用户设备进行随机分组， 这种方式简单易行， 其中考虑到有些用户设备是 旧版本（legacy )的 UE或初始接入该基站的 UE， 则基站无法获取这些 UE的 干扰状态等信息， 且旧版本的 UE处理干扰的能力较弱， 这样基站可以将旧 版本和 /或初始接入该基站的用户设备分到同一个分组中； 且基站在进行分 组时， 可以限定每个分组中用户设备的个数， 或分组的总数量等信息。 其 中旧版本的 UE是指不支持全双工标准的用户设备。
步錄 102， 为各个分组的用户设备配置无线资源图案， 具体可以包括以 下资源中的至少一种： 时域资源使用图案（比如时域子帧的使用图案）， 频 域资源使用图案（比如频域资源块的使用图案）， 时频域资源使用图案， 码 域资源使用图案以及空域资源使用图案等， 其中， 为同一分组内的用户设 备配置的无线资源图案相同， 为不同分组之间用户设备配置的无线资源图 案不同。
可以理解， 在无线通信***中， 无线资源根据使用情况， 可以分为上 行无线资源， 下行无线资源， 空闲无线资源和灵活无线资源。 其中上行和 下行无线资源是必要的。 且无线资源根据属性不同， 主要包括时域、 频域、 码域和空域资源。 而无线资源图案是指基站对时域、 频域、 码域和 /或空域 资源的配置图案， 或者说是 UE对时域、 频域、 码域和 /或空域资源的使用图 案， 即规定哪些无线资源用作上行无线资源， 哪些无线资源用作下行无线 资源， 哪些无线资源用作空闲无线资源， 哪些无线资源用作灵活无线资源。 其中， 空闲无线资源是指基站或 UE在该无线资源上既不接收数据也不发送 数据， 灵活无线资源是指基站或 UE在该无线资源上不受约束， 可以接收数 据， 也可以发送数据。
步骤 103， 根据配置的无线资源图案， 选择在相同无线资源上分别处于 不同通信状态的多个用户设备（至少两个用户设备） 进行通信， 这里通信 状态包括上行传输状态和下行接收状态。
基站在配置了无线资源图案后， 在与用户设备进行通信时， 可以先进 行上下行配对， 并与配对的用户设备进行全双工的无线通信。 其中上下行 配对是指选择相同无线资源上分別处于不同通信状态的多个用户设备； 而 在同一无线资源上， 对于某一个用户设备来说， 只能处于一种通信状态， 即处于上行传输状态或处于下行接收状态。 进行上下行配对的多个用户设 备中， 在相同的无线资源上有些用户设备进行上行传输， 另一些用户设备 进行下行接收。 这样基站在某些无线资源上， 可以在发送下行数据的同时 接收某些或某个用户设备的上行数据。
当基站对各个分組的用户设备配置无线资源图案后， 由于同一分组内 的 UE使用的无线资源图案相同， 无法进行上下行配对， 只有不同分组间的 UE在某些无线资源上， 才会分别出现不同的通信状态， 可以进行上下行配 对。 例如， 基站给分组 1配置上下行子帧配置 0, 给分组 2配置上下行子帧配 置 2， 其中在子帧号为 3， 4， 8和 9的子帧上， 分组 1中的 UE处于上行发送状 态， 分组 2中的 UE处于下行接收状态， 则基站可以在子帧号为 3， 4 , 8和 9 的子帧上， 对分组 1和分组 2的 UE进行上下行配对。
需要说明的是， 如果基站将初始接入的 UE和 /或旧版本 UE分到同一分 组， 考虑到基站无法准确获知该分组中用户设备的干扰情况等因素， 基站 可以不对该分组的 UE与其他分组的 故上下行配对，即基站在相同无线资 源上， 不选择该分组的用户设备， 及与该分组的用户设备具有不同通信状 态的其它分组的用户设备进行通信， 具体地， 基站不会在某些无线资源上 既接收该分组用户设备的上行数据 , 又发送下行数据给其它分组的用户设 备。
进一步地， 在本实施例中， 当基站配置了无线资源图案后， 可以通过 高层信令或下行控制信道承载的信令将配置的无线资源图案通知给相应的 用户设备。其中，下行控制信道承载的信令属于物理层信令；高层信令（High Layer Signaling )是相对物理层信令来说的， 是来自更高层面且发送频率更 慢的信令， 可以包括无线资源控制（RRC, Radio Resource Control )信令和 媒体接入控制 （MAC, Media Access Control )信令等。 优选地， 基站通过 专用的 RRC ( dedicated RRC )信令将各个用户设备的无线资源图案分别通 知每个用户设备。
可见， 在本发明实施例中， 在基站支持全双工无线通信的***中， 基 站需要对其服务范围内的用户设备进行分组， 并为同一分组的用户设备配 置相同的无线资源图案， 为不同分组的用户设备配置不同的无线资源图案， 这样在基站根据配置的无线资源图案， 选择在相同无线资源上通信状态不 同的多个用户设备进行通信过程中， 并不是每个用户设备都会接收到其它 用户设备发送的上行数据， 只有不同分组之间的用户设备才可能在相同无 线资源上分别具有不同的通信状态， 这样可以降低目前全双工无线通信系 统中， 由于每个用户设备都会接收到其它用户设备的上行数据， 而导致的 用户设备之间的干扰； 如果基站在对用户设备进行分组时， 将干扰较小的 用户设备分到不同的分组， 这样会更进一步地降低目前全双工无线通信系 统中用户设备之间的干扰。
在其它具体的实施例中， 基站在执行上述步骤 102时， 可以有如下的几 种情况：
( 1 )无线资源是时域资源时：
当时域资源通过子帧（subframe )来计量时， 无线资源图案可以是时域 子帧的使用图案（简称子帧图案）， 即规定哪些子帧用作上行子帧， 哪些子 帧用作下行子帧， 哪些子帧用作空闲子帧， 哪些子帧用作灵活子帧。 此时， 基站给同一分组的 UE配置相同的子帧图案，给不同分組的 UE配置不同的子 帧图案。
其中， 对于支持 TDD的***， 子帧图案可以但不限于现有 LTE TDD Release-8***中定义的 7种上下行子帧配置 （ UL-DL subframe allocation ) , 例如， 基站给分组 1中用户设备配置上下行子帧配置 0, 给分组 2中用户设备 配置上下行子帧配置 2; 对于分组间用户设备的千扰较强的场景， 基站可以 给不同的分组配置完全不同的可使用子帧， 例如： 基站配置分组 1中用户设 备仅使用奇数子帧， 配置分组 2中用户设备仅使用偶数子帧。
( 2 )无线资源是频域资源时：
当频域资源通过资源块（Resource block, RB )来计量时， 无线资源图 案可以是频域 RB的使用图案 （简称 RB图案）， 即规定哪些 RB用作上行 RB, 哪些 RB用作下行 RB , 哪些 RB用作空闲 RB , 哪些 RB用作灵活 RB。 此时， 基站给同一分组的 UE配置相同的 RB图案， 给不同分组的 UE配置不同的 RB 图案。
对于分组间用户设备的干扰较强的场景， 基站可以给不同分组的用户 设备配置完全不同的可使用 RB,例如： 基站配置分组 1中用户设备仅使用系 统带宽中的前半部分 RB ,配置分组 2中用户设备仅使用***带宽中的后半部 分 RB。
( 3 )无线资源是时频域资源时：
时频域资源的使用图案即是哪些 RB和子帧用作上行资源，哪些 RB和子 帧用作下行资源， 哪些 RB和子帧用作空闲资源， 哪些 RB和子帧用作灵活资 源。 此时， 基站给同一分组的 UE配置相同的时频域资源图案， 给不同分组 的 UE配置不同的时频域资源图案。
( 4 )无线资源是码域资源， 比如 N种正交码或低相关码的资源等， 基 站给同一分组的 UE配置相同的码域图案，给不同分組的 UE配置不同的码域 图案。 例如， 基站配置分组 1中用户设备使用正交码 1 , 配置分组 2中用户设 备使用正交码 2等。
( 5 )无线资源是空域资源， 比如空中波束资源等， 基站给同一分组的 UE配置相同的空域图案， 给不同分組的 UE配置不同的空域图案， 例如， 基 站配置分组 1中用户设备使用空中波束 1到 η , 配置分组 2中用户设备使用控 制波束 n+1到 m。
参考图 2所示， 在另一个具体的实施例中， 为了更准确地根据各个分组 的用户设备的实际情况来减小干扰， 基站在执行上述步骤 103之前还执行步 骤 104到 106:
步骤 104，为各个分组的用户设备配置参考信号（ Reference Signal, RS ) 资源， 即规定哪些无线资源用作用户设备发送 RS, 具体地， 基站为同一分 组的用户设备配置相同的参考信号资源， 为不同分组的用户设备配置不同 的参考信号资源， 其中该 RS用于测量比如测量干扰强度等参数。
步骤 105， 将基站为第二分组的用户设备配置的参考信号资源的指示信 令发送给选定的第一分组的用户设备， 这里第一分组和第二分组并不表示 顺序关系， 而是为了说明不同的分组。
在本实施例中， 基站可以将为每个分组的用户设备配置的参考信号资 源的指示信令发送给任一分组的用户设备， 例如第一分组的用户设备， 这 样对于第一分组的用户设备来说， 可以根据指示信令知道其他分组的用户 设备的 RS资源， 并在其它分组 （例如第二分組） 的用户设备的 RS资源上， 接收其它分组的用户设备发送的 RS , 可以通过测量接收的 RS的参数信息 (比如强度等信息）得知该分組的用户设备与其它分组的用户设备之间干 扰情况， 并将测量结果上报给基站。
例如， 当基站将第二分组的 RS资源发送给第一分组的用户设备， 这样 第一分组的用户设备就可以在第二分组的 RS资源上， 接收第二分组的用户 设备发送的参考信号， 并对该参考信号进行测量， 且可以将测量结果上报 给基站。
步骤 106, 基站接收上述第一分组用户设备发送的， 对第二分组用户设 备发送的参考信号的测量结果， 该测量结果用于指示第一分组和第二分组 之间用户设备的干扰信息， 比如上报的测量结果可以是接收的参考信号的 强度等参数信息， 如果该参考信号的强度越大则用户设备之间的干扰越大。
在执行完步骤 106之后， 在执行步骤 103时， 不仅需要根据配置的无线 资源图案， 还需要根据接收的测量结果来进行上下行配对并与上下行配对 的用户设备进行全双工的无线通信， 即选择在相同无线资源上分別处于不 同通信状态， 且相互之间的千扰小于预置范围的用户设备进行通信。 例如， 如果基站接收的测量结果是某一分组用户设备上报的其它分组用户设备发 送的参考信号的强度， 则将该分组用户设备与发送的参考信号强度小于预 置的值的其它分组用户设备进行上下行配对， 即将干扰较小的用户设备进 行配对。
优选地， 上述的 RS资源可以为信道状态信息参考信号 （Channel State Information Reference Signal, CSI RS ) 资源。 采用 CSI RS来进行测量用户 设备之间的干扰， 对于旧版本的 UE来说具有后向兼容性， 即旧版本的 UE在 接收到某一分组 UE发送的 CSI RS后，可以使用现有协议来测量干 4无并上报， 即将该 CSI RS视为其它小区发送的信息进行测量。
需要说明的是， 上述步骤 102与步骤 104之间没有决定的顺序关系， 可 以同时进行， 也可以顺序进行， 图 2中所示的只是其中具体的实施例。
在其它具体的实施例中， 基站除了可以执行上述步驟 101到 106， 还需 要为各个分组的用户设备配置***信息 （System information, SI ), 以便于 让用户设备知道接入的***中的参数信息， 具体地， 为同一分组的用户设 备配置相同的***信息， 为不同分組的用户设备配置部分不同的***信息。 其中 SI是无线通信***运行的必要参数， 可以包括一个主信息块（Master Information Block, MIB )和多个不同类型的***信息块（ System Information Blocks, SIB )。 SIB包括多种类型， 例如目前***中包括 SIB1 , SIB2, ... , SIB 13等。
基站配置的 SI时， 配置的有些 SI是相同的例如***带宽， 有的 SI是不同 的， 因此基站给不同分组的 UE配置的 SI可以部分不同。 例如， 基站给不同 的分组的用户设备配置不同的 SIB1 , 具体地， SIB1中的部分信息单元 ( Information element， IE )可以被配置成不同， 例如用于指示上下行子帧 配置和特珠子帧图案的 tdd-Config , 用于指示 SI调度窗长的 si-WmdowLength 和用于指示***信息变化的 systemlnfoValueTag等； 基站可以给不同分组的 用户设备配置不同的 SIB2,例如， SIB2中的物理上行链路控制信道（Physical Uplink Control Channel, PUCCH ) 配置信息等。
当基站在配置了 SI后， 可以将 SI通知给用户设备， 具体可以通过如下几 种方式来通知：
( 1 )通过 SI的无线网络临时标识（ Radio Network Temporary Identifier, RNTI ) 即 SI-RNTI加扰的物理层下行控制信道（Physical Downlink Control channel, PDCCH )承载的信令， 将所述配置的***信息中公共的***信息 的调度信息或基线分组（ Baseline Group ) 的***信息的调度信息通知给用 户设备。 另夕卜， 基站可以改变对各个分组配置的 SI， 并将公共的 SI或者基线 分组的 SI的更新指示信息的调度信息通过寻呼 RNT Paging RNTI, P- NTI ) 加扰的 PDCCH承载的信令通知给用户设备。 上述调度信息包括时频域资源 分配信息比如位置和个数等， 还可以包括调制编码方式 （ Modulation and Coding Scheme, MCS ) 信息等。
其中， 公共的 SI是指配置给所有分组的 SI中相同的 SI; 基线分组是指基 站从所有分组中选定一个分组作为基线分组； SI-RNTI加扰的 PDCCH承载的 信令是指将 SI-RNTI与 PDCCH承载的信令经过一定运算比如异或运算得到 的新的信号； P-RNTI加扰的 PDCCH承载的信令是指将 P-RNTI与 PDCCH承 载的信令经过一定运算比如异或运算得到的新的信号。 且本实施例中所述 的 SI-RNTI的值为 FFFF ( 16进制表示）， P-RNTI的值为 FFFE ( 16进制表示）。 ( 2 )通过不同的组无线网络临时标识 （Group RNTI, G-RNTI )加扰 的物理层下行控制信道承载的信令， 将配置的***信息中各个分组的*** 信息的调度信息通知给相应的用户设备。
基站在将各个分组的 SI的调度信息通知给每个用户设备时，对于同一个 分組的 UE可以采用相同的 G-RNTI , 对于不同分组的 UE釆用不同的 G-RNTI, 优选地， 基站可以通过专用 RRC信令分別通知每个 UE所使用的 G-RNTL其中 G-RNTI可以用于产生每个分组对应的信道和信号。 需要说明 的是， 本发明实施例中， 把标识不同组的 RNTI称为 G-RNTI, 但也不限于该 名称。
( 3 )基站通过 SI-RNTI加扰的 PDCCH承载的信令将所有分組的 SI的调 度信息通知给用户设备，这样用户设备接收到 SI-RNTI加扰的 PDCCH承载的 信令，就可以根据该调度信息获取所有分组的用户设备的 SI,可以更好的进 行干扰协调。
为了更进一步地进行干扰协调和干扰消除， 从而降低 UE间的干扰， 基 站可以将其它一些信息可也作为***信息通知给用户设备， 例如序列组号
( sequence group number ), 主辅频带 ( rimary and secondary bands )和最大 发射功率 （max transmitting power ) 等。 其中， 如果上下行都釆用 ZC
( Zadoff-Chu )序列时， 因为上行和下行数据可以在相同的无线资源传输， 基站给不同分组的用户设备分配不同的 ZC序列组， 并把 ZC序列组号作为 SI 通知给用户设备； 基站给不同分组的用户设备配置不同的主辅频带以降低 分组间用户设备的干扰， 每个分組的用户设备优选在主频带上进行上下行 传输， 并对传输信息进行限制后 （如降低功率）在辅频带上进行传输； 基 站可以给不同分组的用户设备配置不同的最大上行或下行发射功率。
需要说明的是， 上述基站给用户设备配置 SI的步骤， 与上述图 2中的步 骤 102和 104之间没有绝对的顺序关系， 可以同时进行， 也可以顺序进行。
本发明实施例提供一种无线通信方法， 用于在 LTE、 LTE-A、 3G、 以及 WiMAX等无线通信***中，基站侧可以支持全双工无线通信， 而 UE侧可以 不支持全双工无线通信的场景下进行的无线通信。 其中用户设备可以按照 如下的步骤进行无线通信， 流程图如图 3所示， 包括：
步骤 201 , 获取基站为用户设备配置的无线资源图案的信息， 所述无线 资源图案和与该用户设备在同一分组的其它用户设备的无线资源图案相 同， 且与该用户设备不在同一分组的其它用户设备的无线资源图案不同。 其中在同一分组的用户设备之间的干扰较小， 或是具有相同的业务参数或 复用技术或多址接入技术， 或是都是属于初始接入基站的用户设备或旧版 本的用户设备。
可以理解， 基站为用户设备配置无线资源图案， 主要包括时域资源使 用图案， 或频域资源使用图案， 或时频域资源使用图案， 或码域资源使用 图案， 或空域资源使用图案， 其具体的配置过程见图 1和图 2对应的实施例 所述， 在此不进行赞述。
当用户设备获取的无线资源图案的信息， 就可以知道该用户设备的哪 些无线资源用作上行资源或下行资源或空闲资源或灵活资源等， 从而知道 与基站通信的过程中， 在哪些子帧和 /或资源块上接收下行数据或发送上行 数据。 具体地， 用户设备可以通过高层信令或下行控制信道承载的信令来 获取无线资源图案的信息， 优选地， 可以通过专用的 RRC信令来接收基站 发送的该用户设备的无线资源图案的信息。
步骤 202, 根据获取的无线资源图案的信息， 与基站进行无线通信。 在基站与用户设备进行全双工的无线通信过程中， 基站会对用户设备 进行上下行配对， 即选择在相同无线资源上分别处于不同通信状态的多个 用户设备， 并与上下行配对的用户设备进行通信， 而用户设备则根据基站 配置的无线资源图案的信息与基站进行通信。
可见， 在本发明实施例中， 基站为同一分组的用户设备配置相同的无 线资源图案， 为不同分组的用户设备配置不同的无线资源图案， 当用户设 备获取了自己的无线资源图案的信息后， 在根据该无线资源图案的信息与 基站进行无线通信的过程中， 并不是每个用户设备都会接收到其它用户设 备发送的上行数据， 只有不同分组之间的用户设备才可能在相同无线资源 上分别具有不同的通信状态， 这样可以降低目前全双工无线通信***中， 由于每个用户设备都会接收到其它用户设备的上行数据， 而导致的用户设 备之间的干扰； 如果基站在对用户设备进行分组时， 将千扰较小的用户设 备分到不同的分组， 这样会更进一步地降低目前全双工无线通信***中用 户设备之间的干扰。
在一个具体的实施例中， 基站可以为各个分组的用户设备配置参考信 号的资源， 即规定用户设备在哪些无线资源上发送参考信号， 其中， 基站 为相同分组的用户设备配置的参考信号资源相同， 为不同分组的用户设备 配置的参考资源不同。
而基站可以将其中一个分组的参考信号资源的指示信令发送给各个分 组的用户设备， 如果用户设备接收到基站为该用户设备所在分组配置的参 考信号资源的指示信令， 则在该指示信令所指示的资源上发送参考信号； 如果用户设备接收到基站为与该用户设备在不同分组的其它用户设备配置 的参考信号资源的指示信令， 当在该指示信令所指示的参考信号资源上， 接收到其它分组的用户设备发送的参考信号， 则对接收的该参考信号进行 测量比如测量接收的参考信号的强度等参数， 并将测量结果上报给基站， 以便基站根椐测量结果选择在相同无线资源上分别处于不同通信状态， 且 之间的千扰小于预置范围的用户设备进行通信， 其中测量结果用于指示所 述用户设备与其它分组的用户设备的干扰信息。
在另一个具体的实施例中， 基站可以为各个分组的用户设备配置*** 信息并通知给用户设备， 其中， 基站为相同分组的用户设备配置的***信 息相同， 为不同分组的用户设备配置的***信息可以部分不同。 其中*** 信息可以包括一个主信息块和多个不同类型的***信息块， 还可以包括： 序列组号， 主辅频带和最大发射功率等信息。
具体地， 当用户设备接收到 SI-RNTI加扰的 PDCCH承载的信令，可以获 取基站为用户设备配置的***信息中公共***信息的调度信息， 或基线分 组的***信息的调度信息； 如果用户设备接收到 P-RNTI加扰的 PDCCH承载 的信令， 则可以获取公共的 SI或者基线分组的 SI的更新指示信息的调度信 息； 如果用户设备接收到 G-RNTI加扰的 PDCCH承载的信令， 则可以获取当 前用户设备所在分组的***信息的调度信息； 如果用户设备接收到 SI-RNTI 加扰的 PDCCH承栽的信令， 则可以获取所有分组的 SI的调度信息。
上述的调度信息可以包括时频域资源分配信息比如位置和个数等， 还 可以包括 MCS信息等。
本发明实施例还提供一种基站， 该基站能支持全双工无线通信， 结构 示意图如图 4所示， 包括：
分组单元 10, 用于对基站服务范围内的用户设备进行分组， 具体地： 该分组单元 10可以将干扰较大的用户设备分到同一分组中， 将干扰较 小的用户设备分到不同的分组， 比如， 分组单元 10获取所述基站服务范围 内用户设备的路损信息， 并将路损相差小于预置的路损范围的用户设备分 到同一个分组； 分组单元 10还可以获取所述基站服务范围内用户设备的业 务参数， 并将业务参数一致的用户设备分到同一个分组， 所述业务参数包 括业务量和 /或业务类型； 分组单元 10还可以获取所述基站服务范围内用户 设备所支持的复用技术和 /或多址接入技术， 并将支持相同复用技术和 /或多 址接入技术的用户设备分到同一个分组； 分组单元 10还可以对所述基站服 务范围内的用户设备进行随机分组。
资源图案配置单元 11， 用于为分组单元 10分组后的各个分组的用户设 备配置无线资源图案， 其中， 为同一分组内的用户设备配置的无线资源图 案相同， 为不同分组之间用户设备配置的无线资源图案不同； 无线资源图 案可以包括以下资源的至少一种： 时域资源使用图案， 频域资源使用图案， 时频域资源使用图案， 码域资源使用图案及空域资源使用图案等。
通信单元 12， 用于根据所述资源图案配置单元 11配置的无线资源图案， 选择在相同无线资源上分别处于不同通信状态的多个用户设备进行通信。
进一步地， 如果分组单元 10将旧版本的用户设备和 /或初始接入所述基 站的用户设备分到同一个分组； 则通信单元 12在相同无线资源上， 不选择 该分组的用户设备， 及与该分组的用户设备具有不同通信状态的其它分组 的用户设备进行通信， 即不对该分组和其他分组的用户设备进行上下行配 对后进行通信。
在本发明实施例的基站中， 分组单元 10对其服务范围内的用户设备进 行分组， 资源图案配置单元 11为同一分组的用户设备配置相同的无线资源 图案， 为不同分组的用户设备配置不同的无线资源图案， 这样在通信单元
12根据配置的无线资源图案， 选择在相同无线资源上通信状态不同的多个 用户设备进行通信过程中， 并不是每个用户设备都会接收到其它用户设备 发送的上行数据， 只有不同分组之间的用户设备才可能在相同无线资源上 分别具有不同的通信状态， 这样可以降低目前全双工无线通信***中， 由 于每个用户设备都会接收到其它用户设备的上行数据， 而导致的用户设备 之间的干扰； 如果分组单元 10在对用户设备进行分组时， 将干扰较小的用 户设备分到不同的分组， 这样会更进一步地降低目前全双工无线通信*** 中用户设备之间的干扰。
参考图 5所示， 在一个具体的实施例中， 基站除了可以包括如图 4所示 的结构外， 还可以包括资源图案通知单元 13、 参考资源配置单元 14、 参考 资源通知单元 15、 测量结果接收单元 16、 ***信息配置单元 17和***信息 通知单元 18, 其中：
资源图案通知单元 13 , 用于通过高层信令或下行控制信道承载的信令 将所述配置的无线资源图案通知给相应的用户设备， 优选地， 资源图案通 知单元 13可以通过专用的 RRC信令将各个用户设备的无线资源图案分别通 知每个用户设备。
参考资源配置单元 14， 用于为同一分組的用户设备配置相同的参考信 号资源， 为不同分组的用户设备配置不同的参考信号资源。
参考资源通知单元 15， 用于将为第二分组的用户设备配置的参考信号 资源的指示信令发送给第一分组的用户设备。
测量结果接收单元 16, 用于接收所述第一分组用户设备发送的对于第 二分组用户设备发送的参考信号的测量结果； 所述测量结果用于指示所述 第一分组和第二分组之间用户设备的千扰信息， 例如该测量结果是第一分 组用户设备接收第二分组用户设备发送的参考信号的强度信息等， 该强度 越大则千扰越大。
***信息配置单元 17， 用于为同一分組的用户设备配置相同的***信 息， 为不同分组的用户设备配置不同的***信息， 这里的***信息可以包 括一个主信息块和多个不同类型的***信息块， 还可以包括： 序列组号、 主辅频带和最大发射功率等。
***信息通知单元 18， 用于通过***信息的无线网络临时标识加扰的 物理层下行控制信道承载的信令， 将所述配置的***信息中公共的***信 息的调度信息或基线分组的***信息的调度信息通知给所述用户设备； 或， 用于通过***信息的无线网络临时标识加扰的物理层下行控制信道承载的 信令， 将所述配置的所有分组的***信息的调度信息通知给所述用户设备； 或， 用于通过寻呼无线网络临时标识加扰的物理层下行控制信道承栽的信 令， 将所述配置的公共的***信息的更新指示信息的调度信息， 或基线分 组的***信息的更新指示信息的调度信息通知给所述用户设备； 或， 用于 通过不同的组无线网络临时标识加扰的物理层下行控制信道承载的信令， 将所述配置的***信息中各个分组的***信息的调度信息通知给相应的用 户设备。
本发明实施例的基站中， 分组单元 10在进行分组后， 资源图案配置单 元 11可以开始配置各个分组的用户设备的无线资源图案， ***信息配置单 元 17也可以开始配置各个分组的用户设备的***信息， 参考资源配置单元 14也可以开始配置各个分组的用户设备的参考信号资源； 并由资源图案通 知单元 13将配置的无线资源图案通知给用户设备来进行通信， ***信息通 知单元 18将配置的***信息通知用户设备来进行***的运行， 由参考资源 通知单元 15将配置的参考信号资源通知给用户设备来进行参数的测量。
当用户设备根据参考资源通知单元 15通知的参考信号资源进行测量 后， 将测量报告发送给基站， 当测量结果接收单元 16接收到该测量结果， 则通信单元 12可以选择在相同无线资源上分别处于不同通信状态， 且相互 之间的千扰小于预置范围的用户设备进行通信， 即将根据无线资源图案及 测量结果将干扰较小的用户设备进行上下行配对， 并选择上下行配对的用 户设备进行通信。 这样根据不同分组的用户设备之间测量的信息可以得到 不同分组的用户设备的实际干扰情况， 从而根据干扰情况来选择通信， 更 进一步地降低了用户设备之间的干扰。
本发明实施例中还提供一种用户设备， 该用户设备可以不支持全双工 通信， 结构示意图如图 6所示， 包括：
资源图案获取单元 20， 用于获取基站为用户设备配置的无线资源图案 的信息， 所述无线资源图案和与所述用户设备在同一分组的用户设备的无 线资源图案相同， 且与所述用户设备不在同一分组的用户设备的无线资源 图案不同。
无线通信单元 21， 用于根据该资源图案获取单元 20获取的无线资源图 案的信息与基站进行无线通信， 即在相应的资源上接收和 /或发送数据。
在本发明实施例中， 基站为同一分组的用户设备配置相同的无线资源 图案， 为不同分组的用户设备配置不同的无线资源图案， 当用户设备的资 源图案获取单元 20获取了自己的无线资源图案的信息后， 在无线通信单元 21根据该无线资源图案的信息与基站进行无线通信的过程中， 并不是每个 用户设备都会接收到其它用户设备发送的上行数据， 只有不同分组之间的 用户设备才可能在相同无线资源上分别具有不同的通信状态， 这样可以降 低目前全双工无线通信***中， 由于每个用户设备都会接收到其它用户设 备的上行数据， 而导致的用户设备之间的干扰； 如果基站在对用户设备进 行分组时， 将干扰较小的用户设备分到不同的分组， 这样会更进一步地降 低目前全双工无线通信***中用户设备之间的干扰。
参考图 7所示， 在一个具体的实施例中， 用户设备除了可以包括如图 6 所示的结构外， 还可以包括： 参考指示接收单元 22、 参考信号通信单元 23 和测量上 4艮单元 24， 其中：
参考指示接收单元 22, 用于接收基站为与该用户设备在不同分组的其 它用户设备配置的参考信号资源的指示信令， 也可以接收该用户设备的参 考信号资源的指示信令。 其中不同分组的用户设备的参考信号资源不同， 同一分组的用户设备的参考信号资源相同。
参考信号通信单元 23， 用于在所述参考指示接收单元 22接收的其它分 组的用户设备的参考信号资源的指示信令所指示的参考信号资源上， 接收 所述其它用户设备发送的参考信号； 如果参考指示接收单元 22接收到当前 用户设备所在分组的参考信号资源的指示信令， 则参考信号通信单元 23还 可以在该指示信令所指示的资源上发送参考信号， 以便其他分组的用户设 备测量与该用户设备之间的千扰情况。
测量上报单元 24 , 用于对所述参考信号通信单元 23接收的其它分組的 用户设备的参考信号进行测量比如测量该参考信号的强度信息等， 并将测 量结果上报给所述基站， 以便所述基站根据所迷测量结果选择在相同无线 资源上分别处于不同通信状态， 且之间的干扰小于预置范围的用户设备进 行通信； 所述测量结果用于指示所述用户设备和其它分组的用户设备的干 扰信息。
进一步地， 该用户设备还可以包括： ***信息接收单元 24 , 用于接收 所述基站为所述用户设备配置的***信息， 所述***信息和与所述用户设 备在同一分组的用户设备的***信息相同， 且与所述用户设备不在同一分 组的其它用户设备的***信息部分不同， 具体***信息包括一个主信息块 和多个不同类型的***信息块， 还可以包括： 序列组号、 主辅频带和最大 发射功率等。
具体地，当***信息接收单元 24接收到 SI-RNTI加扰的 PDCCH承载的信 令， 可以通过该信令得知基站为该用户设备配置的***信息中公共的*** 信息的调度信息或基线分組的 SI的调度信息，或得知所有分組的***信息的 调度信息； 当接收到 P-RNTI加扰的 PDCCH承载的信令， 则可以通过该信令 得知公共的***信息或基线分组的 SI的更新指示的调度信息； 当接收到 G-RNTI加扰的 PDCCH承载的信令，则可以通过该信令得知基站为该用户设 备配置的***信息的调度信息。
本发明实施例还提供一种无线通信***， 包括基站和多个用户设备， 其中：
