Description

无线通信的方法和设备
本申请要求于2017年1月04日提交中国专利局、申请号为201710005001.9、申请名称为“无线通信的方法和设备”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
本申请实施例涉及通信领域,并且更具体地,涉及一种无线通信的方法和设备。
背景技术
在无线通信***中,由于无线信道的时变特性和多径衰落给信号传输带来的影响,通常采用混合自动重传(Hybrid Automatic Repeat Request,HARQ)的方式来进行差错控制。在LTE***中,通常并行存在N个不同的HARQ进程。对于每一个HARQ进程,第一数据传输和最早的下一次传输间的时间间隔为HARQ的最小环回时间RTT。为了允许终端设备(User Equipment,UE)在HARQ RTT期间内休眠,每个下行HARQ进程定义了一个HARQ环回时间定时器,在UE收到指示下行传输的PDCCH的子帧或接收下行数据的最后一个子帧启动。对于上行异步HARQ而言,每个上行HARQ进程定义了一个上行HARQ环回时间定时器,在UE发送上行数据的最后一个子帧启动。
在LTE FDD***中,HARQ环回时间定时器固定为8个子帧,上行HARQ环回时间定时器固定为4个子帧。
然而,固定时长的HARQ环回时间定时器和上行HARQ环回时间定时器无法满足不同应用场景的需要,如在时延敏感的场景中,应该使用更短的定时器,让UE尽快醒过来接收数据;在时延不敏感的场景中,应该使用更长的定时器。
因此,亟待提出一种时长可配置的HARQ环回时间定时器和上行HARQ环回时间定时器,能够灵活适应不同应用场景。
发明内容
本申请实施例提供一种无线通信的方法和设备,能够根据应用场景的不同,灵活配置第一定时器(下行HARQ环回时间定时器或上行HARQ环回时间定时器)和第二定时器(上行重传定时器或下行重传定时器)。
第一方面,提供了一种无线通信的方法,包括:获取第一空口格式的特征信息和/或第一传输数据的特征信息;根据该第一空口格式的特征信息和/或该第一传输数据的特征信息,确定第一定时器的时长,该第一定时器用于表示在该第一定时器的时长内不要求监听下行控制信道PDCCH。
可选地,第一定时器可以是上行HARQ环回时间定时器或下行HARQ环回时间定时 器。
可选地,该第一定时器在发送或收到该第一传输数据时启动。

具体实施方式
下面将结合附图,对本申请实施例中的技术方案进行描述。
图1是使用本申请的无线通信的通信***的示意图。如图1所示,该通信***100包括网络设备102,网络设备102可包括多个天线,例如,天线104、106、108、110、112和114。另外,网络设备102可附加地包括发射机链和接收机链,本领域普通技术人员可以理解,发射机链可以是发射***或发射机,接收机链可以是接收***或接收机,发射机链和接收机链均可包括与信号发送和接收相关的多个部件(例如,处理器、调制器、复用器、解调器、解复用器或天线等)。
网络设备102可以与多个终端设备(例如终端设备116和终端设备122)通信。然而,可以理解,网络设备102可以与类似于终端设备116或122的任意数目的终端设备通信。终端设备116和122可以是例如蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位***、PDA和/或用于在无线通信***100上通信的任意其它适合设备。
如图1所示,终端设备116与天线112和114通信,其中天线112和114通过前向链路118向终端设备116发送信息,并通过反向链路120从终端设备116接收信息。此外,终端设备122与天线104和106通信,其中天线104和106通过前向链路124向终端设备122发送信息,并通过反向链路126从终端设备122接收信息。

本申请实施例中的接收端(发送端)可以是终端设备,该终端设备可以指接入终端、用户设备(User Equipment,UE)、用户单元、用户站、移动站、远方站、远程终端、移动终端、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、物联网中的终端设备、虚拟现实设备、未来5G网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)中的终端设备等。
本申请实施例提供的无线通信的方法和设备,可以应用于终端设备或网络设备,该终端设备或网络设备包括硬件层、运行在硬件层之上的操作***层,以及运行在操作***层上的应用层。该硬件层包括中央处理器(Central Processing Unit,CPU)、内存管理单元(Memory Management Unit,MMU)和内存(也称为主存)等硬件。该操作***可以是任意一种或多种通过进程(Process)实现业务处理的计算机操作***,例如,Linux操作***、Unix操作***、Android操作***、iOS操作***或windows操作***等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且,在本申请实施例中,无线通信的方法的执行主体的具体结构,本申请并未特别限定,只要能够通过运行记录有本申请实施例的传输数据的方法的代码的程序,以根据本申请实施例的传输数据的方法进行通信即可,例如,本申请实施例的无线通信的方法的执行主体可以是终端设备或网络设备,或者,是终端设备或网络设备中能够调用程序并执行程序的功能模块。
