Description

一种信道状态信息上报的方法及装置和一种电子设备 技术领域
本发明涉及无线通信技术,尤其是涉及一种信道状态信息上报的方法及装置和一种电子设备。
背景技术
MIMO(Multiple-Input Multiple-Output,多输入多输出)技术已经被广泛地应用在无线通信***中来提高***容量和保证小区的覆盖,如LTE(Long Term Evolution,长期演进)***的下行采用了基于多天线的发送分集、开环/闭环的空分复用和基于DM-RS(Demodulation Reference Signal,解调参考信号)的多流传输,其中基于DM-RS的多流传输是LTE-A(LTE-Advanced)***以及后续***的主要传输模式。基于DM-RS的多流传输的流程是:UE(User Equipment,用户设备)首先根据eNB(evolved Node B,演进型基站)配置的CSI-RS(CSI:Channel State Information,信道状信息,RS:Reference Signal,参考信号)进行信道测量,测量结果包括传输秩(Rank)、传输秩所对应的预编码矩阵以及传输秩和预编码(Precoding)矩阵对应的CQI(Channel Quality Indicator,信道质量指示);然后UE把测量结果反馈给eNB;eNB再根据UE反馈的测量结果进行下行调度,并根据调度结果把PDSCH(Physical Downlink Shared Channel,物理下行共享信道)通过DM-RS发送给UE。
在通信标准中,例如当前LTE-A Rel-13标准中,三维MIMO的CSI上报和反馈可以分为没有对CSI-RS资源进行预编码的机制一和对CSI-RS资源进行了预编码的机制二。在机制二中,为了克服UE因移动而带来的影响并提高CSI反馈的精确度,基站通常发送多套预编码后的候选参考信号资源以供UE进行选择和上报。不同于机制一中只上报CSI的机制,机制二中UE还需进行额外的作用了多套预编码的资源的选择,然后向基站上报波束选择指示。不过机制一中并不涉及波束的选择和上报,机制二在实现时无法专用机制一的方案,所以在现有技术中机制二下尚未有有效的方案可实现波束选择指示的上报。

具体实施方式
为了使本技术领域的人员更好地理解本发明实施例中的技术方案,并使本发明实施例的上述目的、特征和优点能够更加明显易懂,下面结合附图对本发明实施例中技术方案作进一步详细的说明。
图1为本发明实施例提供的一种信道状态信息上报的方法的流程图。该方法可用于第二设备。例如第二设备可以为手机、平板电脑等用户终端。
参见图1所示,该方法可以包括:
步骤S101,获取待上报的CSI信道状态信息,所述信道状态信息包括第一部分和第二部分,所述第一部分包括用于波束选择的指示信息,所述第二部分包括所述信道状态信息中用于波束选择的指示信息之外的其他信息。
步骤S102,使用预设上报方式向第一设备上报所述信道状态信息;
其中,所述预设上报方式包括方式一或方式二;
所述方式一包括:将所述第一部分放在第一信道上进行传输,将所述第二部分放在第二信道上进行传输;
所述方式二包括:将所述第一部分和所述第二部分均放在所述第一信道上进行传输。
作为示例,所述第一信道为PUSCH(Physical Uplink Shared Channel,物理上行共享信道),所述第二信道为PUCCH(Physical Uplink Control Channel,物理上行控制信道)。
本实施例首先将待上报的信道状态信息分为两部分,所述第一部分包括用于波束选择的指示信息,所述第二部分包括所述信道状态信息中用于波束选择的指示信息之外的其他信息如CQI(Channel Quality Indicator,信道质量指示)、RI(Rank Indicator秩指示)、PTI(Precoding Type Indicator,预编码类型指示)等。
然后第二设备可以在方式一和方式二中选择一种方式上报所述信道状态信息。作为示例,第二设备可以自主选择其中一种方式,也可以根据第一设备的指示来选择其中一种方式。
作为示例,在方式一中,上报时可以采用PUSCH加PUCCH联合传输的方式,将用于波束选择指示的上报量,如bit流形式的波束选择指示或预编码矩阵形式的波束选择指示,放在PUSCH上进行传输,而对于波束选择指示外的其他信道状态信息,如CQI、RI、PTI等信道状态信息放在PUCCH上进行传输。基站基于上述PUSCH上的波束选择指示的上报信息和PUCCH上的其他信道状态信息的上报信息联合得到完整的信道状态信息。
在本实施例或本发明其他某些实施例中:
对于方式一,所述第二部分的传输格式或编码格式采同第三代合作伙伴计划3GPP长期演进LTE标准中PUSCH上传输的CQI信道质量指示的传输格式或编码格式。CQI信道质量指示的传输格式例如可以包括CQI在PUSCH上的映射方式等。
PUCCH上的信道状态信息的上报可采用当前标准中现存的PUCCH上报类型 和模式。如所有的PUCCH report mode,PUCCH 1-0,1-1,2-0,2-1等均可使用。而PUSCH上用于波束选择指示的上报格式或编码格式可以复用当前LTE标准中CQI的PUSCH上报格式或编码格式。
对于方式二,可将第一部分和第二部分同时放在PUSCH上进行传输。通过高层信令或层一动态信令来指示PUSCH上传输的信道状态信息时是仅包含第一部分信道状态信息的方式一还是同时包含了第一部分和第二部分信道状态信息的方式二。或在具体的PUSCH上报模式中增加一个指示字段域,所述指示字段用来指示上报模式为方式一还是方式二。
参见图2所示,在本实施例或本发明其他某些实施例中,所述方法还包括:
在所述使用预设上报方式上报所述信道状态信息之前:
步骤S201,接收所述第一设备发来的第一指示信息,所述第一指示信息用于对所述第二设备的预设上报方式进行指示。
例如作为第一设备的基站通过第一指示信息指示第二设备使用方式一进校上报,则第二设备如UE按方式一进行上报。
在本实施例或本发明其他某些实施例中,所述第一指示信息由所述第一设备通过高层信令或层一信令通知给所述第二设备。
可选的,所述层一信令为控制信令,所述控制信令中包含用于承载所述第一指示信息的信息位。
PUSCH上的波束选择指示上报可用高层信令,如RRC(Radio Resource Control,无线资源控制)信令,或层一动态信令如DCI(Downlink Control Information,下行控制信息)信令等触发。可选地,当采用PUSCH上的波束选择指示上报时,可在DCI中增加1bit的用于波束选择指示上报的触发域字段(信息位),类似于当前的非周期PUSCH上报的触发方式,当此触发域字段设置为1时,触发PUSCH上的波束选择指示上报,当此触发域字段设置为0时,不触发PUSCH上的波束选择指示上报。
此外第二设备也可以自主决定使用方式一还是方式二进行上报,并将上报方式通知第一设备。所以在本实施例或本发明其他某些实施例中,所述方式一和方式二均还包括:
将第二指示信息放在所述第一信道上进行传输,所述第二指示信息用于说明所述第二设备当前所采用的预设上报方式。
可在PUSCH上报模式中增加一个上报类型指示的字段,如增加一个1bit的字段RTI(Report Type Indicator),此字段用来指示当前的PUSCH上报为上述中的方式一还是方式二,可选地,当RTI为0时,所述上报类型为PUSCH 上报方式一,而当RTI为1时,所述上报类型为PUSCH上报方式二。
在本实施例或本发明其他某些实施例中,所述方式一中,所述第二部分在所述第二信道上的上报周期及子帧偏移量根据所述第一部分中的波束选择指示信息确定。如为用于波束选择的候选波束数目的整数倍。
在机制二中,当用户被配置需支持多个候选波束的多份CSI上报时,当前的PUCCH CSI report格式需要进行相应的扩展,以支持多套CSI的联合上报,多份CSI上报的上报周期,上报子帧偏移量等的设置与用于波束选择的候选波束数目有关。可选地,所述多份CSI上报的上报周期为当前标准中单份CSI上报周期的整数倍。
此外,对于采用PUCCH上报模式的Rel-13一些新用户来说,在一些场景下不需要进行波束选择指示的上报,因此其CSI上报仅包含PUCCH上对应传输的上报信息二即可。此时需要基站通过高层信令或其他层一信令通知用户CSI上报模式为PUSCH加PUCCH联合上报和传输的方式一还是只有PUCCH上报和传输。
在本实施例中,将波束选择指示放在第一信道如PUSCH上进行传输,在机制二下实现了波束选择指示的上报,无需进行PUCCH或PUSCH的新格式设计,且放在PUSCH上进行CSI传输的性能较好,标准改动小,基站配置和实现的自由度大,提高了传输的性能。
