Description
相关申请的交叉引用
本申请主张在2017年8月24日在中国提交的中国专利申请号No.201710770116.7的优先权,其全部内容通过引用包含于此。
本公开涉及通信技术领域,特别是指一种随机接入资源的配置、监测方法、网络设备及终端。
NR标准化讨论中,确定了会在同步信号块(SS Block)和RACH(随机接入)资源之间进行Association(关联),用来确定基站发送Msg 2的发送波束。在这个关联中,需要考虑针对不同的因素,尽量设置相同的参数组来指示这个关联,这些因素包括:基站端的波束赋形形式,基站端的波束一致性的情况,同步信号块的个数,PRACH(物理随机接入)资源数,PRACH资源的时间密度等。
一种最简单的关联的方式为,如图1所示,一个SS block对应一个RACH资源,这里一个RACH资源指的是基站端RMSI中RACH配置信息中配置下来的一个preamble format(前导码序列格式)所需占用的时频资源。
这种方式会导致RACH资源占据的时间过长,如在高频段,L=64的情况下,代表在一个同步信号块传输周期内,基站最多可以传64个SS block,这样为了与每个SS block一一对应,需要64个时域PRACH资源,以高频段PRACH format至少为1个symbol为例,总共需要64个符号。即使是预留全上行时隙,也至少需要5个时隙资源(每个时隙有14个符号);如果考虑一些更实际的上下行和周期配置,有可能需要64个时隙甚至更多。当终端需要进行Msg1重传时,新的可用资源时间上间隔较远,这样会导致终端RACH时延过大。

图1为相关技术的同步信号块与RACH资源的一对一的对应关系的示意图;
图2为本公开的随机接入资源的配置方法流程图;
图3为本公开的同步信号块与RACH资源的一种对应关系示意图。
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。
同步信号块与RACH资源在时域上的关联关系在模拟波束赋形架构下适用,但是时域资源占用多,会影响终端接入时延。
为了降低终端接入时延,降低时域PRACH资源开销,并且考虑到模数混合和全数字的波束赋形架构,基站需要支持更灵活统一的同步信号块与RACH资源的关联关系的配置方案。
如图2所示,本公开的实施例提供一种随机接入资源的配置方法,包括:
步骤21,产生同步信号块与随机接入资源关联关系的配置信息,所述同步信号块包括:N个同步信号块,N个同步信号块是由不同数字波束传输的,所述关联关系为:N个同步信号块对应的N个随机接入资源中,至少2个随机接入资源的时域位置相同;其中,N为大于或者等于2的正整数;
步骤22,向终端发送所述配置信息。

本公开的实施例中,所述N个随机接入资源中,第N1个随机接入资源一直到第N1+L个随机接入资源的时域资源的位置相同,其中,N1为N个随机接入资源中除最后一个之外随机接入资源中的任意一个,L为步长。
本公开的实施例中,所述第N1+L个随机接入资源的频域资源位置与所述第N1个随机接入资源的频域资源位置间隔一固定值。
本公开的实施例中,所述配置信息中还包括:随机接入过程中终端可以使用的前导码序列格式的配置信息,所述前导码序列格式的配置信息中包括终端发送前导码序列时可用的符号数和/或时隙数。
在模数混合的波束赋形架构下,基站发送不同同步信号块可以使用不同模拟波束或相同模拟波束下的不同数字波束。
考虑到数字波束部分可以依靠终端基带处理获得,不需要在接收资源上进行区分,因此,如图3所示。可以将这部分同步信号块所对应的RACH资源配置在同一个符号的资源上。
实施例一:RACH配置格式
前导码序列格式字段:配置给终端可以使用的Preamble format(前导码序列格式),终端据此可以得到相应的符号数n,具体见下表:
同步信号块与RACH的关联关系配置字段:至少包括如下时域位置配置字段
该表格中的SS block1-4,SS block 1与SS block 2可以为相同的模拟波束 不同的数字波束传输的同步信号块,SS block 3和SS block 4可以为相同的模拟波束不同的数字波束传输的同步信号块;因此,SS block 1与SS block2分别的RACH资源的时域资源相同,均为奇数子帧的奇数时隙,所占符号为从时隙最后一个符号向前数n个符号开始到最后一个符号,这里仅为举例说明,并不限于表格中所列出的情形。
实施例二:RACH配置格式
前导码序列格式字段:配置给终端可以使用的前导码序列格式,终端据此可以得到相应的符号数n。
同步信号块与RACH的关联关系配置字段:至少包括如下时域位置配置字段
对应相同符号上频分复用RACH资源的SS block数字段:m;
如m=2,表示,从SSblock 1开始,共有两个SS block对应的PRACH时域资源位置相同,即SS block1和SSblock 2;
从SS block 3开始,共有两个SS block对应的PRACH时域资源位置相同,即SS block3和SSblock 4;
PRACH频域资源间隔字段:N
RB,Gap,指示相同符号上的两个PRACH资源频域间隔;
上表看出,SSblock 1的频域起始位置为N
RB,1,那么SS block 2的频域起始位置为N
RB,1+N
RB,Gap;
SSblock 3的频域起始位置为NRB,2,那么SS block 4的频域起始位置 为N
RB,2+N
RB,Gap。实施例三:RACH配置格式
前导码序列格式字段:配置给终端可以使用的前导码序列格式,终端据此可以得到相应的符号数n。
同步信号块与RACH的关联关系配置字段:至少包括如下时域位置配置字段
本公开的上述实施例中,不同的SS block映射到的PRACH资源占据相同的时域资源(相同符号),其中频域位置可相同,可不同。
在5G系统中,将多个SS block所对应的RACH资源配置在同一个符号的资源上,可以降低终端接入时延,该方案也综合考虑了模数混合和全数字的波束赋形架构,支持更灵活统一的映射方案。
