基站及其通知非周期信道状态信息报告的触发模式的方法 Base station and method for notifying trigger mode of aperiodic channel state information report

技术领域 Technical field

本发明涉及通信领域中的非周期信道状态信息（ Channel State Information, CSI )报告，尤其涉及一种基站及其通知非周期 CSI报告的触发模式的方法。背景技术 The present invention relates to aperiodic channel state information (CSI) report in the field of communications, and in particular, to a base station and a method for notifying a trigger mode of an aperiodic CSI report. Background technique

在第三代合作伙伴计划长期演进系统（ The 3rd Generation Partnership Project Long Term Evolution, 3 GPP LTE )中，用户设备 ( User Equipment, UE ) 根据下行参考信号（reference signal )获得下行信道的信道状态信息（Channel State Information, CSI )后，将获得的 CSI反馈给基站（eNodeB, eNB )。基站根据 UE反馈的 CSI,确定发送给 UE的数据的调制编码方式和物理资源位置，以及传输模式。 In the 3rd Generation Partnership Project Long Term Evolution (3GPP LTE), a user equipment (UE) obtains channel state information of a downlink channel according to a downlink reference signal (reference signal) ( After the Channel State Information (CSI), the obtained CSI is fed back to the base station (eNodeB, eNB). The base station determines the modulation and coding mode and physical resource location of the data transmitted to the UE, and the transmission mode according to the CSI fed back by the UE.

在 LTE 系统中， CSI 包括三种形式：信道质量指示（Channels Quality In the LTE system, CSI includes three forms: Channel Quality Indicator (Channels Quality)

Indication, CQI )、预编码矩阵指示（ Pre-coding Matrix Indicator, PMI )和秩指示（ Rank Indicator, RI ) 。 Indication, CQI), Pre-coding Matrix Indicator (PMI) and Rank Indicator (RI).

LTE系统中，UE对下行信道的 CSI反馈有周期反馈和非周期反馈两种方式，分别称为周期信道状态信息报告 ( eriodic CSI reporting, 也称周期 CSI 报告）和非周期信道状态信息报告 ( aperiodic CSI reporting, 也称非周期 CSI 报告）。所谓周期 CSI报告，是指 UE按照基站的配置，周期性地反馈 CSI; 所谓非周期 CSI报告，是指基站通过触发命令触发 UE反馈一次 CSI。 In the LTE system, the CSI feedback of the downlink channel of the UE has two methods: periodic feedback and aperiodic feedback, which are called periodic channel state information report (eriodic CSI reporting, also called periodic CSI report) and aperiodic channel state information report (aperiodic). CSI reporting, also known as acyclic CSI reporting). The so-called periodic CSI report means that the UE periodically feeds back CSI according to the configuration of the base station. The so-called aperiodic CSI report means that the base station triggers the UE to feed back a CSI by using a trigger command.

对于周期 CSI报告，一般来说，某个子帧（subframe )上如果 UE没有发送物理上行共享信道（Physical Uplink Shared Channel, PUSCH ) , 则 CSI在物理上行控制信道（Physical Uplink Control, PUCCH )上传输；如果 UE发送 PUSCH,则 CSI承载在 PUSCH上传输。对于非周期 CSI报告，则只在 PUSCH 上传输。 LTE系统中，基站通过上行调度授权（ Uplink grant, UL grant )信令调度某个 UE发送 PUSCH。上行调度授权信令可由具有下行控制信息（Downlink Control Information, DCI )格式 0 ( format 0 ) 的物理下行控制信道 ( Physical Downlink Control Channel, PDCCH )发送给所调度的 UE。 DCI format 0中有 1比特用于触发 UE反馈非周期 CSI报告的触发命令，称为信道质量指示请求 ( CQI request ) 。 For a periodic CSI report, in general, if a UE does not send a Physical Uplink Shared Channel (PUSCH) on a certain subframe, the CSI is transmitted on a Physical Uplink Control (PUCCH); If the UE transmits a PUSCH, the CSI bearer is transmitted on the PUSCH. For aperiodic CSI reporting, it is only transmitted on the PUSCH. In the LTE system, the base station schedules a certain UE to send a PUSCH by using an uplink grant authorization (UL grant) signaling. The uplink scheduling grant signaling may be sent to the scheduled UE by a Physical Downlink Control Channel (PDCCH) having Downlink Control Information (DCI) format 0 (format 0). One bit in DCI format 0 is used to trigger a trigger command for the UE to feed back an aperiodic CSI report, called a channel quality indication request (CQI request).

如果 UE检测到属于它的具有 DCI format 0格式的 PDCCH, 则根据其中包含的 UL grant发送 PUSCH。如果 UE检测到 DCI format 0中的 1比特 CQI request置为 "1" , 则在该 DCI format 0所调度的 PUSCH中发送非周期 CSI 报告。 If the UE detects a PDCCH having its DCI format 0 format, it transmits a PUSCH according to the UL grant contained therein. If the UE detects that the 1-bit CQI request in DCI format 0 is set to "1", the aperiodic CSI report is sent in the PUSCH scheduled by the DCI format 0.

根据 PDCCH传输的物理资源，定义公有 ( common )搜索空间（Search space )和用户设备专有（ UE-Specific )搜索空间。 According to the physical resources transmitted by the PDCCH, a common search space and a user-specific (UE-Specific) search space are defined.

高级长期演进（ LTE-Advanced , LTE-A ) 系统是 LTE系统的下一代演进系统，釆用载波聚合（Carrier Aggregation, CA )技术扩展传输带宽，支持更大的峰值传输速率。 The Advanced Long Term Evolution (LTE-Advanced, LTE-A) system is a next-generation evolution system for LTE systems. Carrier Aggregation (CA) technology is used to extend the transmission bandwidth and support larger peak transmission rates.

图 1是根据现有技术给出的 LTE-A系统载波聚合示意图。如图 1所示，每个聚合的载波称为一个 "分量载波" （ Component Carrier, CC ) , 也称为一个 "小区" （cell ) 。多个（如未特别说明，本发明说明书中的 "多个" 均表示两个或两个以上）分量载波可以位于同一频段（ frequency band ) , 也可以位于不同频段。 FIG. 1 is a schematic diagram of carrier aggregation of an LTE-A system according to the prior art. As shown in Figure 1, each aggregated carrier is called a "Component Carrier" (CC), also known as a "cell". Multiple (if not specifically stated, "multiple" in the specification of the present invention means that two or more component carriers can be located in the same frequency band or in different frequency bands.

在 LTE-A系统中，物理上行共享信道 PUSCH可釆用单天线端口传输，也可釆用多天线端口传输。单天线端口传输的 PUSCH由 PDCCH DCI format 0 调度，多天线端口传输的 PUSCH由 PDCCH DCI format 4调度。在 DCI format 0和 DCI format 4中均包含非周期 CSI报告的触发命令。 In the LTE-A system, the physical uplink shared channel PUSCH can be transmitted by using a single antenna port or by using multiple antenna ports. The PUSCH transmitted by the single antenna port is scheduled by the PDCCH DCI format 0, and the PUSCH transmitted by the multi-antenna port is scheduled by the PDCCH DCI format 4. Trigger commands for aperiodic CSI reports are included in both DCI format 0 and DCI format 4.

在 LTE-A系统中，基站可为用户设备配置（ configure )或激活（ activate ) 一个或多个分量载波用于发送下行信号，用户设备则需要对所述配置的 ( configured )或激活的（activated )各分量载波反馈 CSI。按照 LTE系统中非周期 CSI报告的触发方式，对时分双工（ Time Division Duplex, TDD ) 系统，基站要触发用户设备反馈某个分量载波的非周期 CSI报告，就必须调度所述用户设备在所述分量载波上发送 PUSCH;对频分双工（ Frequency Division Duplex, FDD )系统，基站要触发用户设备反馈某个下行分量载波（ Downlink Component Carrier, DL CC )的非周期 CSI报告，就必须调度所述用户设备在所述下行分量载波对应的上行分量载波（ Uplink Component Carrier, UL CC ) 上发送 PUSCH。进而在用于调度所述 PUSCH的下行控制信息格式（包括 DCI format 0和 DCI format 4 )的 PDCCH中，发送 1比特（bit )置为 "1" 的触发命令 CQI request, 以触发用户设备对所述分量载波反馈非周期 CSI报告。 In the LTE-A system, the base station may configure or activate one or more component carriers for transmitting downlink signals for the user equipment, and the user equipment needs to be configured or activated (activated). Each component carrier feeds back CSI. According to the triggering mode of the aperiodic CSI report in the LTE system, for the Time Division Duplex (TDD) system, the base station must trigger the user equipment to feed back the aperiodic CSI report of a component carrier. The user equipment sends a PUSCH on the component carrier; for a Frequency Division Duplex (FDD) system, the base station triggers the user equipment to feed back a non-periodic CSI of a downlink component carrier (DL CC). It is reported that the user equipment must be scheduled to transmit the PUSCH on an uplink component carrier (UL CC) corresponding to the downlink component carrier. And in the PDCCH for scheduling the downlink control information format (including the DCI format 0 and the DCI format 4) of the PUSCH, sending a trigger command CQI request with a bit set to "1" to trigger the user equipment pair The component carrier feedback aperiodic CSI report.

除此之外，在 LTE-A FDD系统中，每一个下行分量载波都有一个上行分量载波与之对应。这种上下行分量载波的对应关系是预先设定的，并由基站通过第二类系统信息块（ System Information Block Type2 , SIB-2 )通知给 UE。因而， LTE-A FDD 系统中上下行分量载波的对应关系又称为 SIB-2对应或 SIB-2关联（SIB-2 linkage ) , 一对上下行分量载波互为 SIB-2对应的（关联的）分量载波（ SIB-2 linked CC ) 。 In addition, in the LTE-A FDD system, each downlink component carrier has an uplink component carrier corresponding thereto. The correspondence between the uplink and downlink component carriers is preset, and is notified to the UE by the base station through a second type of system information block (System Information Block Type 2, SIB-2). Therefore, the correspondence between the uplink and downlink component carriers in the LTE-A FDD system is also referred to as SIB-2 correspondence or SIB-2 linkage, and the pair of uplink and downlink component carriers are corresponding to each other by SIB-2 (associated ) Component carrier (SIB-2 linked CC).

基站可为用户设备配置或激活不同数目的上下行分量载波，如图 2所示。其中，至少包括一对用户设备特定的（ UE-specific ) 主分量载波（ Primary Component Carrier, PCC ) , 包括下行 PCC和与之对应的上行 PCC。不同用户设备的主分量载波可能是不同的。除一对主分量载波外，基站还可为用户设备配置或激活一个或多个下行从分量载波 ( Secondary Component Carrier ) , 以及一个或多个上行从分量载波。 The base station can configure or activate different numbers of uplink and downlink component carriers for the user equipment, as shown in FIG. 2. The at least one pair of user equipment-specific (UE-specific) Primary Component Carriers (PCCs) includes a downlink PCC and an uplink PCC corresponding thereto. The primary component carriers of different user equipment may be different. In addition to a pair of primary component carriers, the base station can also configure or activate one or more secondary component carriers and one or more uplink slave component carriers for the user equipment.

在触发 UE上报非周期 CSI时，有可能因为上下行业务不对称，比如，基站在多个分量载波上向用户设备发送数据，可能需要较频繁地触发各分量载波的非周期 CSI报告，于是，基站需要较频繁地调度 UE在相应的分量载波上发送 PUSCH。而实际上，除了所触发的非周期 CSI报告， UE可能并没有多少上行数据需要承载在 PUSCH上发送给基站，从而造成额外的信令开销和上行资源浪费。在 FDD系统中，还有可能基站给 UE配置或激活了某个下行分量载波 DL CC,但未给该用户设备配置或激活该 DL CC对应的上行分量载波 UL CC, 而按照 LTE系统中非周期 CSI报告的触发方式，基站无法触发 UE反馈该 DL CC的非周期 CSI报告。 When the UE is triggered to report the aperiodic CSI, the uplink and downlink services may be asymmetric. For example, if the base station sends data to the user equipment on multiple component carriers, the aperiodic CSI report of each component carrier may be triggered more frequently. The base station needs to schedule the UE to transmit the PUSCH on the corresponding component carrier more frequently. In fact, in addition to the triggered aperiodic CSI report, the UE may not have much uplink data to be transmitted on the PUSCH to the base station, thereby causing additional signaling overhead and waste of uplink resources. In the FDD system, it is also possible that the base station configures or activates a certain downlink component carrier DL CC for the UE, but does not configure or activate the uplink component carrier UL CC corresponding to the DL CC, but according to the aperiodic in the LTE system. The triggering mode of the CSI report, the base station cannot trigger the UE to feed back the aperiodic CSI report of the DL CC.

综上，在 LTE-A系统中，现有的非周期 CSI 4艮告的触发方式不够灵活，可能造成系统资源浪费或者造成 UE无法反馈某些 DL CC的非周期 CSI报告的情形。发明内容 In summary, in the LTE-A system, the triggering method of the existing aperiodic CSI 4 advertisement is not flexible enough. A situation in which system resources may be wasted or the UE may not be able to feed back aperiodic CSI reports of certain DL CCs. Summary of the invention
