一种通信方法及装置 技术领域
本发明涉及通信技术领域， 尤其涉及一种通信方法及装置。 背景技术
目前的无线接入方式只限于传统蜂窝频段接入， 其通信频段在 2.6GHz以 下， 基站（英文全称： Base Station, 简称： BS )与移动台 （英文全称： Mobile Station, 简称： MS )之间、 BS与 BS之间以及 MS与 MS之间都是釆用广播 的方式进行通信。 该广播方式的通信具有波束宽、 覆盖范围广的特点， 同一个 扇区即可视为一个波束， 波束内的 MS通过占用不同频率分用带宽， 波束内的 MS越多， 每个 MS占用的带宽也就越小， 其容量也就越小， 严重限制了用户 传输业务数据容量的大小。
随着网络技术的发展，人类社会必将迎来数字化社会的下一波浪潮， 比如 5G无线网络需要满足更大更快的容量增长需求，也就要求更多的新频谱分配。 随着对高频技术研究的广泛开展，已证实在某些信道的高频通信损耗在可接受 的通信范围内， 由此， 在 6GHz-300GHz高频段所拥有的大带宽使得数据容量 增长成为可能。 由于高频具有波束窄、 能量集中的特点， 使得经过一次反射、 一次衍射或者经过某些物体的穿透之后的能量损耗较小，信号质量仍然可以满 足要求。 高频无线已经成为未来无线通信发展的必然趋势。

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。
本发明实施例中的接收机可以是指基站（英文全称： Base Station, 简称： BS )或者移动台 （英文全称： Mobile Station, 简称： MS )， 发射机也可以是 MS或者 BS， 本发明实施例中的通信包括但不限于 BS与 BS， BS与 MS， MS 与 MS之间的通信， 所述 MS包括用户设备（英文全称： User Equipment, 简 称： UE )。
请参见图 1， 是本发明实施例的一种通信装置的结构示意图， 本发明实施 例的所述装置可具体应用于基站等可作为接收机的通信设备中， 具体的， 所述 装置可包括第一确定模块 10、 第二确定模块 20以及通信模块 30。 其中， 所述第一确定模块 10， 用于当接收到第一侦听参考信号 SRS时， 根据所 述第一 SRS确定与目标发射机之间的主通信路径， 所述目标发射机为发送所 述第一 SRS的发射机。
具体实施例中， 发射机如 UE可按照宽波束接入， 以保证正常通信， 该宽 波束接入的过程与传统无线蜂窝通信接入过程相同， 在此不再赘述。 具体的， 第一确定模块 10可在接收到目标发射机比如新接入的 UE以宽波束全频段发 出的侦听参考信号 （英文全称： Sounding Reference Signal, 简称： SRS )， 即 所述第一 SRS时， 触发确定当前接收机即 BS与该 UE之间的主通信路径。
所述主通信路径可以是指按照传统无线蜂窝通信接入时使用的通信路径， 即信道质量最优的通信路径。 一般而言， 所述主通信路径为直视（英文全称： Line of Sight, 简称： LoS )信道， 在 LoS信道不存在， 或者某些极其特殊情况 下 LoS信道的质量低于非直视（英文全称： non-Line of Sight, 简称： NLoS ) 信道时， 主通信路径为 NLoS信道。 可选地，本发明实施例的所述方法可基于毫米波频段作为通信频段加以实 现。 毫米波是指 30GHz至 300GHz的高频频段， 利用毫米波进行通信， 有较 强的方向指向性以及更为集中的窄波束， 能够获取更高的天线增益。 同时由于 该毫米波波束能量集中的特点，使得对一次反射径或者一次衍射径下的能量损 耗较小， 因此能够用于通信。
所述第二确定模块 20， 用于获取釆用所述第一确定模块 10确定出的主通 信路径进行通信的发射机的标识，并确定每一个标识所指示的发射机的次级通 信路径。
当第一确定模块 10确定目标 UE对应的主通信路径后， 可通过第二确定 模块 20获取该 UE与当前 BS之间的主通信路径波束内所包含的 UE对应的标 识， 即获取釆用该主通信路径进行通信的 UE的标识， 从而为各 UE确定出次 级通信路径， 即除主通信路径外信道质量最优的通信路径。
具体实施例中， 在目标 UE按照传统无线蜂窝通信接入之后， 与该目标 UE对应的 BS即当前接收机可控制将宽波束分裂为窄波束， 将用户分块， 进 而在各自区域内搜索与该 UE对应的次级通信路径， 以提升用户和系统容量。 具体的， 所述次级通信路径在通常情况下可为 NLoS信道。
所述通信模块 30， 用于根据所述第一确定模块 10确定出的主通信路径及 所述第二确定模块 20确定出的次级通信路径， 与所述发射机通信。
具体实施例中，通信模块 30可根据确定得到的该主通信路径波束内的 UE 对应的主通信路径及次级通信路径与该主通信路径波束内 UE的进行通信。
实施本发明实施例在可根据接收机接收到的 SRS信号确定出当前发射机 与目标发射机之间进行通信的主通信路径，并通过为釆用该主通信路径进行通 信的每一个发射机确定次级通信路径，从而基于该主通信路径及次级通信路径 与各发射机进行通信， 有效提升了系统传输容量。
请参见图 2， 是本发明实施例的另一种通信装置的结构示意图， 本发明实 施例的所述装置包括上述通信装置的第一确定模块 10、 第二确定模块 20以及 通信模块 30， 进一步的， 在本发明实施例中， 所述第一确定模块 10可具体包 括：
方向确定单元 101， 用于若接收到第一 SRS， 根据预设的判决规则确定出 来波最优方向。
其中，该第一 SRS是由目标发射机如新接入的 UE通过宽波束全频段发送 的。
若方向确定单元 101接收到该目标 UE以宽波束全频段发送的 SRS信号， 即该第一 SRS， 则可根据预设的判决规则从当前接收到 SRS信号的方向中确 定出来波最优方向，并向该新接入的 UE反馈所述来波最优方向的相关位置信 息。该预设的判断规则可以是根据一定的算法和准则形成的， 比如方向确定单 元 101可根据各个方向的 SRS信号， 获取得到与该各个方向对应的信号与干 扰加噪声比 （英文全称： Signal to Interference plus Noise Ratio, 简称： SINR ) 值， 并选择其中的最大 SINR值对应的方向作为来波最优方向。
波束收窄单元 102， 用于沿着所述方向确定单元 101确定的来波最优方向 对所述目标发射机使用的宽波束进行收窄，将收窄后的波束所在的通信路径确 定为主通信路径。
方向确定单元 101在确定来波最优方向之后，波束收窄单元 102可沿着该 来波最优方向对该 UE使用的宽波束进行收窄，比如通过调整预编码 precoding 模块、 波束成形 beamforming模块等相关波束控制模块， 控制沿着该来波最优 方向收窄波束。 进一步的， 该发出 SRS信号的 UE即目标 UE在接收到 BS反 馈的来波最优方向相关信息后， 也可控制调整预编码 precoding模块、 波束成 形 beamforming模块等相关波束配置模块， 以使沿着该来波最优方向收窄波 束， 得到当前 BS与该目标 UE之间的主通信路径。
进一步的， 在本发明实施例中， 所述第二确定模块 20可包括：
第一路径获取单元 201， 用于获取釆用所述主通信路径进行通信的发射机 的标识， 并根据所述标识中目标标识对应的目标发射机所发送的第二 SRS，确 定所述目标发射机的次级通信路径， 所述目标标识为所述目标发射机的标识； 第二路径获取单元 202， 用于确定所述标识中其他标识所指示的发射机的 次级通信路径。
其中， 该第二 SRS为发射机以窄波束全频段发送的 SRS。
在确定得到当前 BS与该目标 UE之间的主通信路径之后， 可通过第一路 径获取单元 201获取该目标 UE的次级通信路径，并通过第二路径获取单元 202 提取共享该主通信路径的其他 UE对应的次级通信路径，从而确定出釆用该主 通信路径进行通信的所有 UE即该主通信路径波束内的所有 UE对应的次级通 信路径。 其中， 共享该主通信路径的其他 UE为该主通信路径波束内已存在的 UE, 该已存在的 UE与当前 BS之间的次级通信路径可记录保存， 进一步的， 第二路径获取单元 202确定该已存在的 UE的次级通信路径仅需将记录保存的 次级通信路径提取出来即可。

若判断子单元 2011接收到目标 UE以窄波束全频段发送的 SRS， 即该第 二 SRS， 则可根据该 SRS计算该当前时刻方向上的信道质量， 并在计算得到 当前时刻方向上的信道质量之后，将该当前时刻方向上的信道质量与上一时刻 计算得到的信道质量进行对比， 检测是否高于该上一时刻计算得到的信道质 量。
更新子单元 2012， 用于若所述判断子单元 2011判断结果为所述信道质量 高于上一次确定的次级通信路径对应的信道质量，则将所述目标方向对应的通 信路径更新为次级通信路径。
其中， 该更新子单元 2012可具体用于：
若所述判断子单元 2011判断结果为所述信道质量高于上一次确定的次级 通信路径对应的信道质量，判断所述目标方向对应的通信路径是否为所述主通 信路径； 若判断结果是不为所述主通信路径， 则检测所述目标方向对应的通信 路径的信道质量是否高于预设的通信服务质量 QoS阔值， 并在高于所述 QoS 阔值时， 将所述目标方向对应的通信路径更新为次级通信路径。
若判断子单元 2011检测到目标方向即当前时刻方向上的信道质量高于该 上一时刻计算得到的信道质量，则表示可将当前时刻方向对应的通信路径更新 为当前 BS与目标 UE之间的次级通信路径。
进一步的， 在将当前时刻方向对应的通信路径更新为当前 BS与目标 UE 之间的次级通信路径之前，若检测到当前时刻方向上的信道质量高于该上一时 刻计算得到的信道质量，还可进一步检测当前时刻方向对应的通信路径是否为 当前 BS与目标 UE之间的主通信路径。 若不为所述主通信路径， 将该目标方 向对应的通信路径更新为次级通信路径。
进一步的， 若检测到当前时刻方向对应的通信路径不为当前 BS 与目标 UE之间的主通信路径， 还可检测该时刻方向对应的通信路径的信道质量是否 高于预设的服务质量（英文全称： Quality of Service, 简称： QoS )阔值。 若检 测到该时刻方向对应的通信路径的信道质量高于该 QoS 阔值， 则可将所述当 前时刻方向对应的通信路径更新为次级通信路径。 该 QoS 阔值可以根据具体 的信道质量要求进行设置， 本发明实施例不作限制。
具体的， 目标 UE按照预设的时间间隔更改波束指向， 将该更改波束指向 后对应的方向作为目标方向， 向该目标方向上以窄波束全频段发送 SRS。判断 子单元 2011接收目标 UE在该目标方向上发送的 SRS， 计算并确定该方向上 的信道质量，直至第一路径获取单元 201完成对该目标 UE在各个方向上发出 的 SRS的检测，将确定出次级通信路径作为当前 BS与该目标 UE之间的次级 通信路径。
进一步可选地， 确定目标 UE对应的次级通信路径还可以是通过在 BS接 收到该 UE朝各个方向上以窄波束全频段发送的 SRS之后，通过比较计算得到 的各个方向上的信道质量，从该各个信道质量中直接选择出除主通信路径所在 方向的信道质量外、 信道质量最优（满足预设的 QoS 阔值） 的方向所对应的 通信路径作为该目标 UE对应的次级通信路径。

请参见图 3， 是本发明实施例的一种通信方法的交互示意图， 本发明实施 例以 BS (即接收机） 与 UE (即发射机）之间的通信为例进行说明。 具体的， 所述方法包括：
S301: 目标 UE以宽波束全频段发送 SRS。
S302: BS根据 SRS确定出主通信路径。
具体实施例中， UE可按照宽波束接入， 以保证正常通信， 该宽波束接入 的过程与传统无线蜂窝通信接入过程相同。 具体的， 当前 BS可在接收到目标 UE比如新接入的 UE以宽波束全频段发出的 SRS时， 触发确定当前 BS与该 UE之间的主通信路径。
作为一种可选的实施方式， 本发明实施例在确定 BS与目标 UE之间的主 通信路径时， 可通过接收到的 SRS确定出来波最优方向， 从而确定出该主通 信路径。其中，该 SRS是由目标 UE如新接入的 UE通过宽波束全频段发送的。
具体的， 若当前 BS接收到该目标 UE以宽波束全频段发送的 SRS信号， 则可根据预设的判决规则从当前接收到 SRS信号的方向中确定出来波最优方 向， 并向该新接入的 UE反馈所述来波最优方向的相关位置信息。 该预设的判 断规则可以是根据一定的算法和准则形成的， 比如 BS可根据各个方向的 SRS 信号， 获取得到与该各个方向对应的 SINR值， 并选择其中的最大 SINR值对 应的方向作为来波最 ύ方向。
在确定来波最优方向之后， 该 BS及 UE可沿着该来波最优方向对该 UE 使用的宽波束进行收窄， 比如通过调整预编码 precoding模块、 波束成形 beamforming模块等相关波束控制模块， 控制沿着该来波最优方向收窄波束， 并将收窄后的波束所在的通信路径确定为当前 BS与该目标 UE之间的主通信 路径。 S303: 目标 UE调度另一子阵， 以窄波束全频段发送 SRS。
S304: BS根据 SRS确定出目标 UE可用的次级通信路径。
当确定目标 UE的主通信路径后， 可通过获取釆用该 UE与当前 BS之间 的主通信路径进行通信的 UE的标识， 即该主通信路径波束内所包含的各 UE 对应的标识， 确定该每一个标识所指示的 UE的次级通信路径， 即除主通信路 径外信道质量最优的通信路径。
具体实施例中， 在目标 UE按照传统无线蜂窝通信接入之后， 与该目标 UE对应的 BS即当前发射机可控制将宽波束分裂为窄波束， 将用户分块， 进 而在各自区域内搜索与该 UE对应的次级通信路径， 以提升用户和系统容量。 具体的， 所述次级通信路径在通常情况下可为 NLoS信道。
具体的， 该主通信路径波束内包含的 UE可分为新接入的 UE即发送 SRS 的目标 UE， 以及该主通信路径波束内原来已经存在并确定过次级通信路径的 UE。 其中， 可选地， 该目标 UE对应的次级通信路径可通过检测该目标 UE以 窄波束全频段发送的 SRS进行确定。
S305: 确定该主通信路径波束内其他 UE对应的次级通信路径。
进一步可选地，在确定得到当前 BS与该目标 UE之间的主通信路径之后， 还可提取共享该主通信路径的其他 UE所对应的次级通信路径，从而确定出釆 用该主通信路径进行通信的所有 UE即该主通信路径波束内的所有 UE对应的 次级通信路径。 其中， 共享该主通信路径的其他 UE为该主通信路径波束内原 已存在的 UE， 该已存在的 UE与当前 BS之间的次级通信路径可记录保存， 进一步的，确定该已存在的 UE的次级通信路径仅需将记录保存的次级通信路 径提取出来即可。
S306: 根据该主通信路径以及各 UE对应的次级通信路径， 与各 UE进行 通信。
具体实施例中，可根据确定得到的该主通信路径波束内的 UE对应的次级 通信路径来确定该主通信路径波束内 UE对应的上下行链路子帧的帧格式， 即 通信路径波束内的 UE之间的通信。
实施本发明实施例在可根据 SRS信号确定出当前 BS与发送该 SRS的目 标 UE之间进行通信的主通信路径， 并通过为釆用该主通信路径进行通信的每 一个 UE确定次级通信路径， 从而基于该主通信路径及次级通信路径与各 UE 进行通信， 可有效提升系统数据传输的吞吐量及传输效率。
请参见图 4， 是本发明实施例的一种确定次级通信路径的方法的流程示意 图， 本发明实施例的所述方法可具体应用于 BS、 MS等可作为接收机的通信 设备中， 具体的， 所述方法包括： 信号 SRS。
S402: 根据所述 SRS计算得出所述目标方向上的信道质量。
若当前 BS接收到发送 SRS的 UE即目标 UE (目标发射机） 以窄波束全 频段发送的 SRS， 则根据该 SRS计算该当前时刻方向上的信道质量。
S403:判断所述信道质量是否高于上一次确定的次级通信路径对应的信道 质量。
当前 BS在计算得到当前时刻方向上的信道质量之后， 将该当前时刻方向 上的信道质量与上一时刻计算得到的信道质量进行对比，并检测是否高于该上 一时刻计算得到的信道质量。
S404: 若高于， 则将所述目标方向对应的通信路径更新为次级通信路径。 若目标方向即当前时刻方向上的信道质量高于该上一时刻计算得到的信 道质量， 则表示可将当前时刻方向对应的通信路径更新为当前 BS与目标 UE 之间的次级通信路径。
进一步的， 在将当前时刻方向对应的通信路径更新为当前 BS与目标 UE 之间的次级通信路径之前，若检测到当前时刻方向上的信道质量高于该上一时 刻计算得到的信道质量，还可进一步检测当前时刻方向对应的通信路径是否为 当前 BS与目标 UE之间的主通信路径。 若不为所述主通信路径， 将该目标方 向对应的通信路径更新为次级通信路径。 进一步的， 若检测到当前时刻方向对应的通信路径不为当前 BS 与目标 UE之间的主通信路径， 还可检测该时刻方向对应的通信路径的信道质量是否 高于预设的 QoS 阔值。 若检测到该时刻方向对应的通信路径的信道质量高于 该 QoS阔值， 则可将所述当前时刻方向对应的通信路径更新为次级通信路径。 该 QoS阔值可以根据具体的信道质量要求进行设置， 本发明实施例不作限制。
S405:接收所述目标发射机在更改波束指向后对应的方向上以窄波束全频 段发送的 SRS， 并将所述方向上发送的 SRS作为所述目标发射机在目标方向 发送的 SRS。 的检测时， 确定出所述目标发射机的次级通信路径。
目标 UE按照预设的时间间隔更改波束指向，将该更改波束指向后对应的 方向作为目标方向， 向该目标方向上以窄波束全频段发送 SRS。 若当前 BS接 收目标 UE在该目标方向上发送的 SRS， 重复 S402至 S405， 直至当前 BS完 成对该目标 UE在各个方向上以窄波束全频段发出的 SRS的检测，并将确定出 次级通信路径作为当前 BS与该目标 UE之间的次级通信路径。
实施本发明实施例可在当前 BS接收到目标 UE发送的 SRS之后，通过比 较当前时刻方向上的信道质量与上一时刻方向上的信道质量，来确定是否更新 该目标 UE对应的次级通信路径， 并在当前 BS完成对该目标 UE按照预设的 时间间隔在各个方向上以窄波束全频段发出的 SRS的检测后， 将确定出的次 级通信路径作为当前 BS与该目标 UE之间的次级通信路径。
请参见图 5， 是本发明实施例的另一种确定次级通信路径的方法的流程示 意图， 具体的， 所述方法包括： 信号 SRS。
S502: 根据所述 SRS计算所述各个方向上的信道质量。
目标 UE以窄波束全频段朝各个方向发送 SRS， 当前 BS接收该目标 UE 发送的 SRS， 并根据该接收到的 SRS计算各个方向上对应的通信路径的信道 质量。 具体的， 所述朝各个方向发送 SRS可以是通过按照预设的时间间隔更 改波束指向、 并向该更改波束指向后对应的方向以窄波束全频段发送 SRS来 实现的。
S503:根据计算得到的所述各个方向上的信道质量确定出所述目标发射机 的次级通信路径。
当前 BS计算得到各个方向上对应通信路径的信道质量之后， 可从该各个 信道质量中选择出除主通信路径所在方向的信道质量外，信道质量最优的方向 所对应的通信路径作为目标 UE对应的次级通信路径。
进一步的，在将该除主通信路径所在方向的信道质量外，信道质量最优的 方向所对应的通信路径确定为目标 UE对应的次级通信路径之前，还可检测该 通信路径对应的信道质量是否高于预设的 QoS阔值， 若高于该 QoS阔值， 则 可将该通信路径确定为所述目标 UE对应的次级通信路径。
实施本发明实施例可在 BS接收到 UE朝各个方向上以窄波束全频段发送 的 SRS之后， 通过比较计算得出的各个方向上的信道质量， 从该各个信道质 量中直接选择出除主通信路径所在方向的信道质量外，信道质量最优的方向所 对应的通信路径作为目标 UE对应的次级通信路径。
进一步的，根据该主通信路径及次级通信路径与发射机进行通信可包括以 下五种通信场景。
场景一： 若釆用所述主通信路径进行通信的发射机的标识为至少两个，且 每一个标识所指示的发射机均不存在次级通信路径，则按照预设的配置比例对 所述发射机对应的上下行链路子帧的数目进行配置，所述发射机的上下行链路 子帧以时分复用的方式传输；
其中， 所述上下行链路子帧的帧格式相同， 所述上下行链路子帧中包含了 所述发射机对应的信息， 所述发射机以频分复用的方式分配全频段带宽资源。
具体的， 请参见图 6， 是本发明实施例的其中一种通信场景的示意图， 该 场景中釆用所述主通信路径进行通信的发射机可以有多个，即该主通信路径对 应的波束内包含多个发射机，图 6中具体举例为该主通信路径对应的波束内有 三个 UE (即三个发射机）， 分别为 UE1、 UE2以及 UE3， 且每一个 UE均不 存在次级通信路径。
进一步的， 如图 7所示， 是图 6的场景中的资源分配示意图， 具体的， 该 UE1、 UE2以及 UE3之间用频分区分， 上下行链路用时分区分。
进一步的， 各 UE对应的上下行链路的帧格式相同， 如图 8所示， 是图 6 的场景中对应的帧格式的示意图。 其中， 该上下行链路子帧数目可按照预设的 配置比例进行配置 （图 8中按照 4:4进行配置）， 且该配置比例可根据上下行 业务的吞吐量进行调整。 具体的， 可按照预设的插入间隔将 SRS插入至所述 上下行链路子帧中， 比如可在每两个子帧插入一个 SRS信号， 图 8中用阴影 块表示， 该插入的 SRS 可以是当前 BS基于该主通信路径波束内 UE反馈的 SRS信息得到。在下行子帧之间、下行和上行子帧之间插入 SRS时，需将 SRS 信号包裹在特殊子帧 S中来进行插入； 在上行子帧之间插入 SRS时， 只需将 SRS放在最后一个子帧的数据块之后 (或者也可将 SRS包裹在特殊子帧 S中 来进行插入）。 如图 8所示， 每个上行子帧 U和下行子帧 D中根据频率分配可 顺次包含 UE1、 UE2 以及 UE3 的相关信息， 分别对应为 Ul、 U2、 U3 以及 Dl、 D2、 D3。 进一步的， 该 SRS信号的插入间隔可根据移动速度的要求进行 调整。
上述场景一中， 尽管一根波束内有多个 UE (场景一为三个 UE )， 且各 UE没有对应的次级通信路径， 但相对于釆用广播形式的传统无线蜂窝通信系 统， 其波束有一定的收窄， 即每根波束所覆盖的 UE个数相对较少。 因此， 每 个 UE在频分复用频段时能够分得更宽的带宽。 例如一个 300MHz宽的频谱， 则该三个 UE可均分带宽， 每个 UE 占 100MHz带宽， 上行和下行各可支持 100MHz的带宽。 若是广播形式的传统蜂窝通信系统， 每个波束内可能有成百 上千个 UE， 则每个 UE的带宽仅有不到 1ΜΗζ。 因此， UE和系统容量有所提 升。
场景二： 若釆用所述主通信路径进行通信的发射机的标识为一个，且所述 标识所指示的发射机不存在次级通信路径，则按照预设的配置比例对所述发射 机对应的上下行链路子帧的数目进行配置，所述发射机的上下行链路子帧以时 分复用的方式传输；
其中， 所述上下行链路子帧的帧格式相同， 所述上下行链路子帧中包含了 所述发射机的信息， 所述发射机占用全频段带宽资源。
具体的， 请参见图 9， 是本发明实施例的另一种通信场景的示意图， 如图 9所示， 该场景中釆用所述主通信路径进行通信的发射机仅有一个， 即该主通 信路径对应的波束内仅包含一个 UE， 即 UE1，且该 UE不存在次级通信路径， 该场景二可以看作场景一的特例。
进一步的， 如图 10所示， 是图 9的场景中的资源分配示意图， 该主通信 路径波束内 UE1独自占有全频段， 上下行链路用时分区分。
进一步的， 该 UE1对应的上下行链路的帧格式相同， 如图 11所示， 是图 9的场景中对应的帧格式的示意图。 其中， 每个上行 U1和下行子帧 D1中只 包含该 UE1的信息，该上下行链路子帧数目可按照预设的配置比例如 4:4进行 配置， 该配置比例可根据上下行业务的吞吐量进行调整。 具体的， 本场景中 SRS信号的插入方式同上述场景 SRS信号的插入方式， 在此不再赘述。 进一 步的， 该 SRS信号的插入间隔可根据移动速度的要求进行调整。
上述的场景二中， 尽管该 UE没有对应的次级通信路径， 但该波束内只有 一个 UE，该 UE独享带宽资源。例如一个 300MHz宽的频谱，该 UE就占 300MHz 带宽， 上行和下行各可支持 300MHz的带宽。 UE和系统容量显著提升。
场景三： 若釆用所述主通信路径进行通信的发射机的标识为至少两个，且 每一个标识所指示的发射机均存在次级通信路径。
作为一种可选的实施方式，可控制将所述主通信路径用于传输所述标识指 示的各发射机下行链路子帧，所述各发射机的下行链路子帧以频分复用的方式 传输；

上述的场景三中， 一根波束内有多个 UE， 且每个 UE都存在可用次级通 信路径， 所有 UE共享下行链路的频谱资源， 每个 UE独享上行带宽资源。 例 如一个 300MHz 宽的频语， 该波束内有两个 UE， 每个 UE 的下行链路占用 150MHz带宽， 每个 UE的上行链路占用 300MHz的带宽， UE容量和系统吞 吐量都有较大提升。
作为一种可选的实施方式，还可控制将所述主通信路径用于传输所述标识 指示的各发射机上行链路子帧，所述各发射机的上行链路子帧以频分复用的方 式传输；

具体的， 可控制主通信路径仅用于上行链路子帧的传输， 次级通信路径仅 用于下行链路传输， 每个 UE的上下行链路的帧格式不相同， 各自独立， 如图 16所示， 是图 12的场景中的另一种帧格式的示意图。 其中， 每个下行子帧 D 中只包含 UE1或 UE2的信息，分别对应为 D1或 D2;每个上行子帧 U中则可 顺次包含该两个 UE的信息， 即 U 1和 U2。
上述的场景三中， 一根波束内有多个 UE， 且每个 UE都存在可用次级通 信路径， 所有 UE共享上行链路的频谱资源， 每个 UE独享下行带宽资源。 例 如一个 300MHz 宽的频语， 该波束内有两个 UE， 每个 UE 的上行链路占用 150MHz带宽， 每个 UE的下行链路占用 300MHz的带宽， UE容量和系统吞 吐量都有较大提升。
场景四： 若釆用所述主通信路径进行通信的发射机的标识为一个，且所述 标识所指示的发射机存在对应的次级通信路径，则所述发射机的上行链路子帧 与下行链路子帧以空分复用的方式传输，所述上行链路子帧与下行链路子帧的 格式不同， 所述发射机占用全频段带宽资源。
具体的， 请参见图 17， 是本发明实施例的再一种通信场景的示意图， 如 图 17所示， 该场景中共享所述主通信路径的发射机仅有一个， 即该主通信路 径对应的波束内仅包含一个 UE， 即 UE1，且该 UE存在可用的次级通信路径。
进一步的， 如图 18所示， 是图 17的场景中的资源分配示意图， 具体的， 该主通信路径波束内的该 UE可独自占有全频段， 上下行链路用空分区分。
具体的， 可控制主通信路径仅用于下行链路子帧的传输， 次级通信路径仅 用于上行链路传输，反之亦可。该上下行链路子帧的帧格式不相同，各自独立， 如图 19所示，是图 17的场景中对应的帧格式的示意图。 帧格式中不存在上下 行子帧数目的配比问题。 具体的， 每个上行子帧 U1和下行子帧 D1中仅包含 该 UE的信息。 本场景中 SRS信号的插入方式同上述场景所述 SRS信号的插 入方式， 在此不再赘述。 进一步的， 该 SRS信号的插入间隔可根据移动速度 的要求进行调整。
上述的场景四中，一根波束内只有一个 UE，且存在可用的次级通信路径， 该 UE独享带宽资源。例如一个 300MHz宽的频谱，该 UE就占 300MHz带宽， 上行和下行各可支持 300MHz的带宽， UE容量显著提升。
场景五： 釆用所述主通信路径进行通信的发射机的标识为至少两个，存在 的次级通信路径数目大于零， 且存在的次级通信路径数目小于所述标识数目。
具体的， 请参见图 20， 是本发明实施例的再一种通信场景的示意图， 如 图 20所示， 该场景中共享所述主通信路径的发射机有多个， 即该主通信路径 对应的波束内包含多个发射机， 图 20中具体举例为该主通信路径对应的波束 内有两个 UE， 即 UE1与 UE2， 其中， 仅有 UE1存在可用的次级通信路径。
作为一种可选的实施方式，可控制将所述主通信路径用于传输各发射机下 行链路子帧， 所述各发射机的下行链路子帧以频分复用的方式传输， 所述各发 射机包括不存在次级通信路径的第一发射机即 UE2 以及存在次级通信路径的 第二发射机即 UE1;

上述的场景五中， 一根波束内有多个 UE， 但并不是每个 UE都存在可用 次级通信路径， 所有 UE共享下行链路的频谱资源， 拥有次优径的 UE独享上 行带宽资源。 例如一个 300MHz宽的频语， 该波束内有 UE1及 UE2， 且仅有 UE1有对应的次级通信路径， 则每个 UE的下行链路占用 150MHz带宽， UE2 的上行链路占用 150MHz的带宽， 而 UE1的上行链路占用 300MHz带宽， UE 容量和系统吞吐量都有较大提升。
作为一种可选的实施方式，还可控制将所述主通信路径用于传输各发射机 上行链路子帧， 所述各发射机的上行链路子帧以频分复用的方式传输， 所述各 发射机包括不存在次级通信路径的第一发射机即 UE2以及存在次级通信路径 的第二发射机即 UE1;

具体的， 可控制主通信路径仅用于上行链路子帧的传输， 次级通信路径仅 用于下行链路子帧传输。 UE1 的上下行链路帧格式不相同， 各自独立， UE2 的上下行链路帧格式相同，如图 24所示，是图 20的场景中的另一种帧格式的 示意图。 由于 UE1和 UE2共用上行链路和上行波束的帧格式， 因此， 在 UE2 通过时分复用传输下行数据时， 属于 UE1 的带宽只能空闲。 上下行子帧数目 可按预设的配置比例如 4:4进行配置， 进一步的， 还可根据上下行业务吞吐量 进行配比调整。 UE1的下行链路子帧 U1可使用次级通信路径并以空分复用的 方式进行传输， 因此 UE1的下行链路子帧 D1具有独立的帧格式。 具体的， 通 过次级通信路径传输的每个下行子帧 D1中只包含 UE1的信息；通过主通信路 径传输的每个上行子帧 U中则顺次包含了 UE1及 UE2的信息， 即对应为 U1 和 U2。 每个下行子帧 D中属于 UE1的频段空闲， 即图 24中的 X； 属于 UE2 的频段包含 UE2的信息即对应为 D2。 进一步的， 还可通过一定的技术控制在 主通信路径中的下行子帧中 UE1的带宽内发送 UE2的下行数据。
上述的场景中， 一根波束内有多个 UE， 但并不是每个 UE都存在可用次 级通信路径， 所有 UE共享上行链路的频谱资源， 拥有次优径的 UE独享下行 带宽资源。例如一个 300MHz宽的频语，该波束内有 UE1及 UE2，且仅有 UE1 有对应的次级通信路径， 则每个 UE的上行链路占用 150MHz带宽， UE2的下 行链路占用 150MHz的带宽， 而 UE1的下行链路占用 300MHz带宽， UE容量 和系统吞吐量都有较大提升。
根据具体的通信场景确定帧格式， 即为各 UE确定出用于传输上下行链路 子帧的通信路径 （包括主通信路径及相应的次级通信路径）之后， 即可准备
BS与 UE之间的通信。
实施本发明实施例可在当前 BS根据接收到的 SRS确定出与发送 SRS的 UE之间进行通信的主通信路径之后， 进一步确定出与该 UE之间的次级通信 路径， 并提取出该主通信路径波束内已存在的其他 UE的次级通信路径， 并基 于该主通信路径及次级通信路径所确定的通信场景与该主通信路径波束内的 各 UE进行通信， 可有效提升系统数据传输的吞吐量及传输效率。
