Abstract

本发明提供了一种发射天线选择的配置方法及装置,该方法包括:在用户设备配置为或回退到单天线端口模式发射PUSCH或PUCCH的情况下,用户设备选择天线选择掩码所对应的天线端口发射PUSCH或PUCCH,其中,天线选择掩码与用户设备的天线端口一一对应或者与天线端口组一一对应,天线端口组包括一个或多个天线端口。通过本发明可以使支持发射天线选择的用户设备在不同传输模式下选择相应的发射天线端口发射PUSCH或PUCCH。

Description

发射天线选择的配置方法^置 技术领域 本发明涉及通信领域, 具体而言, 涉及一种发射天线选择的配置方法及装 置。 背景技术 在第三代合作伙伴计划 ( The 3rd Generation Partnership Project, 简称为 3GPP ) 长期演进(Long Term Evolution, 简称为 LTE ) 系统中, 上行信号包括 物理上行共享信道 ( Physical Uplink Shared Channel, 简称为 PUSCH ) 及其解 调参考信号 ( Demodulation Reference Signal for PUSCH ), 物理上行控制信道 ( Physical Uplink Control Channel , 简称为 PUCCH ) 及其解调参考信号 ( Demodulation Reference Signal for PUCCH ) , 测量参考信号 ( Sounding Reference Signal, 简称为 SRS ) 等。 在 LTE 系统中, 上行信号釆用单天线端口发射。 但是, 用户设备 (User Equipment, 简称为 UE ) 可支持 1个天线端口 ( Antenna Port ), 称为天线端口 0 ( port 0 ); 也可支持 2个天线端口, 分别称为天线端口 0 ( port 0 ) 和天线端 口 1 ( port 1 )。 支持多天线端口的用户设备可釆用用户设备发射天线选择 ( UE transmit antenna selection ) 技术选择天线端口发射上行信号。 用户设备发射天 线选择由高层配置。 当闭环 (closed-loop ) 用户设备发射天线选择由高层配置使能, 且用户设 备支持发射天线选择时, 用户设备根据最近收到的下行控制信息格式 0 ( Downlink Control Information format 0 , 简称为 DCI format 0 ) 中携带的发射 天线选择配置信息选择天线端口,发射除测量参考信号 SRS以外的其它上行信 号。 下面对下行控制信息格式进行说明。 在 LTE 系统中, 基站 (eNodeB ) 通 过物理下行控制信道( Physical Downlink Control Channel, 简称为 PDCCH )将 下行控制信息 ( Downlink Control Information, 简称为 DCI )发送给用户设备, 其中包括下 /上行调度信息( downlink or uplink scheduling information ), 上行发 射功率控制命令等。 对不同的下行控制信息, LTE系统定义了多种下行控制信 息格式 (DCI format )。 其中, 物理上行共享信道 PUSCH的上行调度信息承载 于具有下行控制信息格式 0 ( DCI format 0 ) 的 PDCCH中; 物理下行共享信道 ( Physical Downlink Shared Channel , 简称为 PDSCH ) 的下行调度信息 载于 具有下行控制信息格式 1A/1B/1C/1D/1/2A/2 ( DCI format 1A/1B/1C/1D/1/2A/2 ) 的 PDCCH中。 当开环 ( open-loop )用户设备发射天线选择由高层配置使能, 且用户设备 支持发射天线选择时, 用户设备如何选择天线端口发射除测量参考信号以外的 其它上行信号, 作为用户设备实现问题, 未标准化。 当用户设备发射天线选择由高层配置使能, 且用户设备支持发射天线选择 时, 用户设备根据一定的规则选择天线端口, 发射测量参考信号。 高级长期演进 ( LTE-Advanced, 简称为 LTE-A ) 系统是 LTE 系统的下一 代演进系统。 在 LTE-A系统中, PUSCH、 PUCCH、 SRS等上行信号可釆用单 天线端口发射,也可釆用多天线端口发射; 用户设备可支持 1个天线端口(port 0 ), 2个天线端口 (port 0/1 ), 或 4个天线端口 ( port 0/1/2/3 )。 对支持多天线端口的用户设备, 定义了一种单天线端口模式 ( Single Antenna Port Mode )„ 该模式下, 从基站 eNodeB角度看, 用户设备的行为与仅 支持单天线端口的用户设备相同。 而对 PUSCH, PUCCH和 SRS , 单天线端口 模式可以独立配置。 需要指出的是, 对支持多天线端口的用户设备, 配置为多 天线端口模式时, 基站可以动态调度用户设备只在一个天线端口上发射上行信 号, 此时, 动态调度信息指示用户设备在多个天线端口中的某一个上发射上行 信号, 这种情况并不同于下面的用户设备配置为或回退到单天线端口模式; 当 用户设备配置为或回退到单天线端口模式时, 动态调度信息并不指示用户设备 在哪个天线端口发射上行信号。 因此, 在目前的 LTE-A系统中, 并没有公开如何配置支持发射天线选择的 用户设备在不同传输模式下选择相应的发射天线端口发送 PUSCH、 PUCCH上 行信号。 发明内容 本发明的主要目的在于提供一种发射天线选择的配置方案, 以至少解决上 述问题。 才艮据本发明的一个方面, 提供了一种发射天线选择的配置方法, 包括: 在 用户设备配置为或回退到单天线端口模式发射物理上行共享信道 PUSCH或物 理上行控制信道 PUCCH的情况下, 所述用户设备选择天线选择掩码所对应的 天线端口发射所述 PUSCH或所述 PUCCH, 其中, 所述天线选择掩码与所述用 户设备的天线端口——对应或者与天线端口组——对应, 所述天线端口组包括 一个或多个所述天线端口。 在所述用户设备配置为或回退到单天线端口模式发射 PUCCH的情况下, 所述用户设备选择当前单天线端口发射 PUSCH的天线端口或最近一次单天线 端口发射 PUSCH的天线端口发射所述 PUCCH。 所述天线选择掩码携带于物理下行控制信道 PDCCH 中, 其中, 所述 PDCCH 为用于在所述用户设备配置为或回退到单天线端口模式时调度所述用 户设备在单天线端口发射所述 PUSCH的 PDCCH。 所述天线选择掩码携带于 PDCCH中; 其中, 所述 PDCCH为 载上行调 度信息的 PDCCH, 所述 PDCCH 包括以下至少之一: 调度所述用户设备在单 天线端口发射所述 PUSCH的 PDCCH、调度所述用户设备在多天线端口发射所 述 PUSCH的 PDCCH。 所述天线选择掩码携带于 PDCCH中; 其中, 所述 PDCCH为 载下行调 度信息的 PDCCH。 如果某一子帧上基站向所述用户设备发送多个能够携带天线选择掩码的 PDCCH, 则基站在所述多个 PDCCH上携带相同的天线选择掩码, 或基站在所 述多个 PDCCH中的一个 PDCCH上携带所述天线选择掩码。 方法还包括: 所述用户设备釆用多天线端口发射所述 PUSCH 或所述
