Description

混合自动重传请求缓存区的配置方法及装置 技术领域
本发明涉及通信领域,尤其是涉及一种混合自动重传请求(Hybrid Automatic Repeat Request,简称为HARQ)缓存区的配置方法及装置。
背景技术
高速下行分组接入(High Speed Downlink Packet Access,简称为HSDPA)及其演进功能,如双载波(Dual Carrier,简称为DC),双频段-双载波(Dual Band-Dual Carrier,简称为DB-DC),多输入多输出(Multiple Input Multiple Output,简称为MIMO)等功能极大的提高了网络的峰值速率和吞吐量,增强和提高了用户的网络体验。但是,DC等技术对运营商的网络频点资源要求比较苛刻,需要同一频段的相邻频点等要求也限制了DC的应用;同时,由于HSDPA没有软切换功能,HSDPA用户处在小区边缘时性能较差,当HSDPA用户处于切换区域时,若能同时利用多个小区的HSDPA资源,则不但能很大程度上提高用户的体验,还能进一步提高网络资源的利用率,提高网络的平均吞吐量。为此,第三代合作伙伴计划(3rd Generation Partnership Project,简称为3GPP)在R11版本引入了多流-高速下行共享分组接入(Multi Flow-HSDPA,简称为MF-HSDPA)技术。MF-HSDPA技术是指位于同一频点的两个高速下行共享信道(High Speed Downlink Shared Channel,简称为HS-DSCH)同时给同一个MF-HSDPA用户调度不同的数据块。使用多流技术的用户最多可以同时接收4个小区的HS-DSCH传输信道,每个小区根据其功能角色,分别定义为:服务高速共享下行信道小区(serving HS-DSCH Cell),辅助服务高速共享下行信道小区(Assisting serving HS-DSCH Cell),辅服务高速共享下行信道小区(secondary serving HS-DSCH Cell),辅助辅服务高速共享下行信道小区(Assisting secondary serving HS-DSCH Cell)。其中,serving HS-DSCH Cell和secondary serving HS-DSCH Cell是双载波小区,Assisting serving HS-DSCH Cell和Assisting secondary serving HS-DSCH Cell是双载波小区;Assisting serving HS-DSCH Cell与serving HS-DSCH Cell频点相同,Assisting secondary serving HS-DSCH Cell与secondary serving HS-DSCH Cell频点相同。相同频点上的两个HS-DSCH信道可以位于同一Node B(节点B)或者不同Node B,即对应MF-HSDPA的两种分流模式:基站内(intra-NodeB)和基站间(inter-NodeB)。对于intra-NodeB模式,协议模型如图1所示,下行数据分流位于高速下行共享信道增强媒体接入控制(Media Access Control enhanced HS-DSCH,简称为MAC-ehs)层,数据发送时共用一个MAC-ehs实体, MAC-ehs实体支持4个HS-DSCH传输信道,每个HS-DSCH信道都有各自相应的上下行信令和HARQ(混合自动重传请求)实体。对于inter-NodeB模式,协议模型如图2所示,下行数据分流位于无线链路控制(Radio Link Control,简称为RLC)层,使用两个MAC-ehs实体用于数据发送,每一个MAC-ehs实体支持两个HS-DSCH传输信道,每个HS-DSCH信道都有各自相应的上下行信令和HARQ实体。
MF-HSDPA作为HSDPA的一个演进功能,为减小时延并增加重发数据的速率,仍然采用HSDPA中的HARQ技术。HARQ是指接收方在解码失败的情况下,保存接收到的数据,并要求发送方重传数据,接收方将重传的数据和先前接收到的数据进行组合(如果不能正确解调出来,需要把之前的和之后的进行合并来实现一个宏分集的作用)。HARQ技术可以提高系统性能,并可灵活地调整有效码元的速率,还可以补偿由于采用链路适配所带来的误码。接收方为了保存数据,需要设置HARQ内存区,对于用户设备(User Equipment,简称为UE)来讲,为了节省成本,内存都是极为宝贵的,需要根据系统配置来合理设置HARQ内存区。对于inter-NodeB模式,UE有两个MAC-ehs实体,serving HS-DSCH Cell和secondary serving HS-DSCH Cell属于一个NodeB,共用一个MAC-ehs实体,Assisting serving HS-DSCH Cell和Assisting secondary serving HS-DSCH Cell属于一个NodeB并共用一个MAC-ehs实体,由于不同的NodeB的HARQ配置不同,而目前的Uu(UE-UTRAN)口消息缺少Assisting serving HS-DSCH Cell和Assisting secondary serving HS-DSCH Cell的HARQ内存配置数据,这样无线网络控制器(Radio Network Controller,简称为RNC)就无法为UE来配置辅助小区的HARQ信息,从而导致MF-HSDPA技术无法得到应用。
针对相关技术中的上述问题,尚无有效地解决方案。

相关技术中,无法为UE配置辅助小区的HARQ信息导致MF-HSDPA技术无法得到应用,基于此,本发明实施例提供了相应的解决方案,以下详细说明。在以下实施例中所述的主小区包括但不限于以下至少之一:服务高速共享下行信道小区、辅服务高速共享下行信道小区;所述的辅助小区包括但不限于以下至少之一:辅助服务高速共享下行信道小区、辅助辅服务高速共享下行信道小区。
图3为根据本发明实施例的HARQ缓存区的配置方法的流程图。如图3所示,该方法包括以下处理步骤:
步骤S302,获取主小区所属第一基站配置的第一HARQ信息,以及辅助小区所属第二基站配置的第二HARQ信息;
步骤S304,判断第一HARQ信息和第二HARQ信息是否相同;
步骤S306,根据判断结果确定第三HARQ信息,其中,该第三HARQ信息用于对UE的HARQ缓存区进行配置;
步骤S308,将第三HARQ信息发送至UE。
无论是UE主小区的缓存区还是辅助小区的缓存区,均可以采用上述处理步骤进行缓冲区配置,尤其是对于辅助小区,可以解决相关技术中无法对辅助小区进行配置的问题,为MF-HSDPA提供了有力支持。
需要说明的是,上述主小区和/辅助小区是可以同时包括一个或多个小区的,也可以包括同时包括两类小区,例如对于主小区同时包括服务高速共享下行信道小区和辅服务高速共享下行信道小区,对于辅助小区同时包括:辅助服务高速共享下行信道小区和辅助辅服务高速共享下行信道小区。
步骤S306的实现方式有多种,例如可以通过以下之至少一方式实现:
(1)在上述判断结果指示相同时,将上述第一HARQ信息或上述第二HARQ信息确定为上述第三HARQ信息;
(2)在上述判断结果指示不同时,将上述第一HARQ信息和上述第二HARQ信息按照预设规则进行合并,得到上述第三HARQ信息。在一个优选实施方式中,对于第(2)种实现方式,上述预设规则包括但不限于以下至少之一:
在第一HARQ信息和第二HARQ信息均包括HARQ进程个数时,以进程个数最大值所对应的HARQ信息作为第三HARQ信息;
在第一HARQ信息和上述第二HARQ信息均包括内存大小时,以内存大小最大值所对应的HARQ信息作为第三HARQ信息;
在第一HARQ信息和第二HARQ信息中的其中一个为显示配置,另一个为隐式配置时,以显示配置对应的HARQ信息作为第三HARQ信息;在一个优选实施过程中,上述隐式配置用于指示对每个HARQ进程的内存进行平均分配;上述显示配置用于指示根据每个进程的内存小区进行辅助小区的缓存区的分配。
以主小区所属基站配置的HARQ信息作为第三HARQ信息。
需要说明的是,本实施例提供的HARQ缓存区的配置方法可以根据需要应用于指定实体中(即上述方法的执行主体为指定实体),在一个优选实施过程中,可以应用于无线网络控制器(RNC)中,这样可以利用现有的一些接口实现,改动较小。
