技术领域
本公开文本涉及通信技术领域，尤其涉及一种上行免调度的方法和装置。
背景技术
第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)提出三种NR(New Radio)场景，分别是海量机器类通信(massive Machine Type Communications，mMTC)、超高可靠超低时延通信(Ultra-Reliable and Low Latency Communications，URLLC)及移动宽带增强(enhanced Mobile Broadband，eMBB)。其中针对mMTC场景其需求为大连接，基于非正交的上行免调度成为满足此场景需求的一种有效传输机制。免调度可以减少大量的信令负载，非正交可以满足系统内大量用户进行连接。当网络内大量用户进行连接时，邻区干扰是网络性能的瓶颈。对于有调度场景，可通过干扰协调解决，对于免掉度则无法实现。
在mMTC场景下，上行基于非正交的免调度传输能满足其大连接广覆盖的要求。由于采用上行免调度传输，大量终端用户会同时进行数据传输，且终端用户随机选取多址接入(Multiple Access，MA)资源，导致基站侧收到的邻区干扰会急剧增加。即使基站侧采用高级接收机，也无法进行邻区干扰删除。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
本领域技术人员知道，本公开文本的实施方式可以实现为一种系统、装置、设备、方法或计算机程序产品。因此，本公开文本的实施例可以具体实现为以下形式：完全的硬件、完全的软件(包括固件、驻留软件、微代码等)，或者硬件和软件结合的形式。
目前针对上行基于非正交免调度机制，邻区干扰控制一般通过部分频率 复用(Fractional Frequency Reuse，FFR)或者软频率复用(Soft Frequency Reuse，SFR)的频率复用方案。针对有调度系统，可以通过小区间干扰协调(Inter Cell Interference Coordination，ICIC)降低邻区干扰。频率复用方案存在可复用资源少等缺点，ICIC对于大连接场景会产生大量信令负载。因此，本公开文本实施例采取基于多址资源特点进行分组及复用来降低邻区干扰。
参见图1，图中示出了一种上行基于非正交免调度的方法，具体步骤如下：
步骤101、基站对多址资源进行分组，配置得到至少两组多址资源池，所述至少两组多址资源池中至少部分多址资源不相同；
以两组多址资源池为例：第一多址资源池和第二多址资源池，其中，第二多址资源池中的部分多址资源与第一多址资源池中的多址资源不同。
以三组多址资源池为例：第一多址资源池、第二多址资源池和第三多址资源池，其中，第二多址资源池与第一多址资源池和第三多址资源池分别相比，均具有不同的多址资源，且第一多址资源池和第三多址资源池相比，也具有不同的多址资源。
上述多址资源包括：时域资源、频域资源、空域资源和码域资源中的任意一种或多种，其中，码域资源包括但不限于：码本(codebook)、码字(codeword)、序列(sequence)、交织器(interleaver)和映射图样(mapping pattern)中的任意一种或多种。
可选地，基站对多址资源进行分组，配置得到第一多址资源池和第二多址资源池，其中，所述第一多址资源池包括：所有或部分正交多址资源，所述第二多址资源池可以包括：系统内所有多址资源或除所述第一多址资源池内多址资源以外的多址资源，即第二多址资源池可以包括除第一多址资源池外的多址资源，也可以是包括第一多址资源池的所有多址资源。
在本实施例中，可选地，第一多址资源池和第二多址资源池通过多址资源池门限值区分。
步骤102、基站将配置得到的至少两组多址资源池通知终端，由所述终端从所述至少两组多址资源池中选择其使用的多址资源池。
相应地，基站将所述第一多址资源池和第二多址资源池通知终端，由所 述终端从所述第一多址资源池和第二多址资源池中选择其使用的多址资源池。
在本公开文本实施例中，基站可以对多址资源进行分组，配置得到至少两组多址资源池，至少两组多址资源池中至少两组中部分多址资源不相同，由终端从至少两组多址资源池中选择其使用的多址资源池，即采用多址资源分组及复用来降低邻区干扰，既不减少可用的多址资源，又不会产生大量信令负载。
参见图2，图中示出了一种上行基于非正交免调度的方法，具体步骤如下：
步骤201、终端获取基站预配置的至少两组多址资源池，所述至少两组多址资源池中至少部分多址资源不相同；
在本实施例中，上述多址资源包括：时域资源、频域资源、空域资源和码域资源中的任意一种或多种，其中，码域资源包括但不限于：码本(codebook)、码字(codeword)、序列(sequence)、交织器(interleaver)和映射图样(mapping pattern)中的任意一种或多种。
在本实施例中，可选地，至少两组多址资源池包括：第一多址资源池和第二多址资源池，其中，所述第一多址资源池包括：所有或部分正交多址资源，所述第二多址资源池包括：系统内所有多址资源或除所述第一多址资源池内多址资源以外的多址资源，即第二多址资源池可以包括除第一多址资源池外的多址资源，也可以是包括第一多址资源池的所有多址资源。
在本实施例中，可选地，第一多址资源池和第二多址资源池通过多址资源池门限值区分。
步骤202、终端从所述至少两组多址资源池中选择其使用的多址资源池。
在本实施例中，可选地，在步骤202中，终端获取测量值，该测量值可以是信号强度、接收质量或者信噪比等测量值，对此本公开文本实施例不作限定；然后终端根据所述测量值和多址资源池门限值，从所述至少两组多址资源池中选择其使用的多址资源池。
在本公开文本实施例中，基站可以对多址资源进行分组，配置得到至少两组多址资源池，至少两组多址资源池中至少两组中部分多址资源不相同，由终端从至少两组多址资源池中选择其使用的多址资源池，即采用多址资源 分组及复用来降低邻区干扰，既不减少可用的多址资源，又不会产生大量信令负载。
需要说明的是，上述实施例中所述的方法是以上行非正交免调度传输为例进行说明的，但本领域技术人员在本公开文本的教诲下能够理解的是，这样的方法也可以类似地应用在上行正交免调度传输的方案中。
下面以PDMA(Pattern Division Multiple Access)上行免调度传输为具体例子阐述本公开文本实施方式。
PDMA技术采用发送端和接收端联合优化的设计思想，在发送端对多个用户的信息进行不等分集度分割，并映射到相同的时域资源、频域资源或空域资源上，利用不同编码图样来区分相同资源重叠的不同用户；在接收端采用高性能低复杂度的多用户检测技术，例如置信传播算法，逼近最大后验概率检测性能。PDMA技术其多址资源特征是不同图样资源共享相同的时域资源、频域资源、空域资源等资源。PDMA多址资源池不同的图样资源拥有不等分集度。
以PDMA 350％过载编码图样矩阵为例，其多址资源池图样资源不等分集度分别为3/2/1，参见图3。
其中所有分集度为1的图样资源组成其多址资源池最大正交组。
三扇区小区如图5所示，cell-1(小区1)下有3个用户(UE1/UE2/UE3)，cell-2(小区2)下有2个用户(UE4/UE5)，cell-3(小区3)下有2个用户(UE6/UE7)；
每扇区下均有图3所示PDMA 350％总编码图样资源池。
步骤1、网络中每扇区内PDMA 350％总编码图样池预配置为两组，如图4所示。两组之间门限为Zgate＝β。其中在PDMA图样资源池1内全部PDMA图样均正交；
步骤2、当UE有数据发送时，首先获得测量值。例如，测量值为SINR＝α，当α≤β时，UE从PDMA图样资源池1随机选择1个PDMA图样；反之，当α＞β时，UE从PDMA图样资源池2随机选择1个PDMA图样。
步骤3、基于上述步骤2，扇区内用户终端(User Equipment，UE)选择PDMA图样如图5所示.
基于上述过程，由于小区边缘用户采用稀疏正交序列，因此小区内用户 收到邻区干扰将会降低。
参见图6，图中示出了一种基站，该基站600包括：
配置模块601，用于对多址资源进行分组，配置得到至少两组多址资源池，所述至少两组多址资源池中至少两组中部分多址资源可以不相同；
