Description

上行控制信息的发送方法、接收方法和装置 技术领域
本发明涉及通信技术领域,尤其涉及上行控制信息的发送方法、接收方法和装置。
背景技术
长期演进(LTE,Long Term Evolution)系统中,时频资源被划分成时间域维度上的正交频分复用多址(OFDM,Orthogonal Frequency Division Multiplexing)或单载波频分复用多址接入(SC-FDMA,Single Carrier–Frequency Division Multiplexing Access)符号(下称时域符号)和频率域维度上的子载波,而最小的资源粒度叫做一个资源单位(RE,Resource Element),即表示时间域上的一个时域符号和频率域上的一个子载波组成的时频格点。LTE系统中,业务的传输是基于基站调度的,基站调度的基本时间单位是一个子帧,一个子帧包括多个时域符号。具体的调度流程是基站发送控制信道,如物理下行控制信道(PDCCH,Physical Downlink Control Channel)或增强的物理下行控制信道(EPDCCH,Enhanced Physical Downlink Control Channel),该控制信道可以承载数据信道,如物理下行共享信道(PDSCH,Physical Downlink Shared Channel)或物理上行共享信道(PUSCH,Physical Uplink Shared Channel)的调度信息,其中,调度信息包括比如资源分配信息和调制编码方式等控制信息。用户设备(UE,User Equipment)在子帧中检测控制信道,并根据检测出的控制信道中承载的调度信息来接收下行数据信道或发送上行数据信道。LTE中在进行数据传输时,将上、下行时频域物理资源组成物理资源块(PRB,Physical Resource Block),一个PRB在频域上包含12个连续的子载波,在时域上包含7个连续的OFDM符号(在Extended CP情况下为6个),即频域宽度Δf为180kHz,时间长度为0.5ms。两个PRB组成一对物理资源块(PRB-Pair,Physical Resource Block-Pair),为物理层信道资源的最小映射粒度。LTE系统支持载波聚合(CA,Carrier Aggregation)技术,即基站把多个载波配置给一个UE来提升UE的数据传输速率。进行CA时,基站发送的多个载波在时间上是同步的,UE分别检测每个载波的PDCCH和相应的PDSCH, 针对每个载波的检测过程与单载波情况类似。LTE系统支持频分双工(FDD,Frequency Duplexing Division)CA,时分双工(TDD,Time Duplexing Division)CA以及FDD+TDD CA。对于TDD CA,又分为相同上下行配置的TDD CA和不同上下行配置的TDD CA。现阶段LTE支持最大5个下行载波的聚合;支持CA技术的UE可能同时检测到的承载在多个下行载波上的下行数据,该UE需要同时对承载在该多个下行载波上的下行数据做混合自动重传请求(HARQ,Hybrid Automatic Repeat Request)的反馈机制。
一种现有的UCI信息的传输方法为:CA模式下有一个主载波和至少一个辅载波,且承载混合自动重传确认请求(HARQ-ACK,Hybrid Automatic Repeat Request-ACKnowledge)的物理上行控制信道(PUCCH,Physical Uplink Control Channel)只在UE的主载波上发送。CA模式下的PUCCH发送模式包括信道选择模式和PUCCH格式3两种模式。信道选择模式下,采用PUCCH格式1a/1b进行HARQ-ACK反馈,但信道选择模式最多支持两个载波的CA,因此在CA模式的应用场景中较为受限;PUCCH格式3模式采用离散傅里叶变换扩展正交频分复用(DFT-S-OFDM,Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing)的发送结构,最多可以支持20比特的UCI的传输,可以支持5个载波的TDD CA。例如,以当前网络中主流部署的TDD上下行配置2为例,一个载波的上行子帧2可以支持4比特的反馈,5个载波的TDD上下行配置2的CA就是20比特。
但是这种传输方法最多只能支持20比特的UCI的传输,无法支持超过20比特的UCI的反馈。
