Description

一種通道狀態資訊回饋方法、下行參考信號方法及裝置 Channel state information feedback method, downlink reference signal method and device

本發明屬於通信技術領域，尤其是關於一種通道狀態資訊回饋方法、下行參考信號發送方法及裝置。 The present invention belongs to the field of communication technologies, and in particular, to a channel state information feedback method, a downlink reference signal transmission method and apparatus.

在長期演進(Long Term Evolution，LTE)版本(Rel)-8中，最多可以支援4層的多輸入多輸出(Multi Input Multi Output，MIMO)傳輸。Rel-9重點對多用戶MIMO(Multi-User MIMO，MU-MIMO)技術進行了增強，傳送模式(Transmission Mode，TM)-8的MU-MIMO(Multi-User MIMO)傳輸中最多可以支援4個下行資料層。Rel-10則通過8埠通道品質資訊參考信號(Channel State Information-Reference Signals，CSI-RS)、使用者專屬參考信號(UE-specific Reference Signal，URS)與多顆粒度碼本的引入進一步提高了通道狀態資訊測量的空間解析度，並進一步將單用戶MIMO(Single-User MIMO，SU-MIMO)的傳輸能力擴展至最多8個資料層。MIMO系統的性能增益來源於天線系統所能獲得的空間自由度。這裡所說的空間自由度即天線系統所支援的CSI-RS埠個數。到目前為止，標準中對於天線系統最多支援8個CSI-RS埠，即對於天線系統所能獲得的空間自由度最大能力支援8。 In the Long Term Evolution (LTE) version (Rel)-8, up to four layers of Multi Input Multi Output (MIMO) transmission can be supported. Rel-9 focuses on multi-user MIMO (Multi-User MIMO) technology, and supports up to 4 MU-MIMO (Multi-User MIMO) transmissions in Transmission Mode (TM)-8. Downstream data layer. Rel-10 is further enhanced by the introduction of 8 Channel Channel State Information-Reference Signals (CSI-RS), User-Specific Reference Signal (URS) and multi-granular codebooks. The spatial resolution of channel state information measurement, and further expands the transmission capability of single-user MIMO (SU-MIMO) to a maximum of 8 data layers. The performance gain of a MIMO system is derived from the spatial freedom that an antenna system can achieve. The spatial freedom referred to here is the number of CSI-RSs supported by the antenna system. Up to now, the standard supports up to 8 CSI-RS埠 for the antenna system, which is the maximum capacity support for the antenna system.

對於採用基於下行參考信號測量並回饋通道狀態資訊 (Channel State Information，CSI)的機制的通信系統，使用者設備(User Equipment，UE)要向基地台回饋預編碼矩陣碼本索引(Precoding Matrix Indicator，PMI)，秩指示資訊(Rank Indicator，RI)和通道品質資訊(Channel Quality Indicator，CQI)。UE回饋的PMI，RI和CQI是基於UE通過CSI-RS所測量得到的通道資訊所計算得到的。這個通道資訊應包括天線系統的所有CSI-RS埠的資訊，才能充分利用天線系統的空間自由度。 For measuring and reporting channel status information based on the downlink reference signal (Channel State Information, CSI) mechanism communication system, user equipment (User Equipment, UE) to feed back to the base station Precoding Matrix Indicator (PMI), Rank Indicator (Rank Indicator, RI) And Channel Quality Indicator (CQI). The PMI, RI and CQI fed back by the UE are calculated based on the channel information measured by the UE through the CSI-RS. This channel information should include all CSI-RS information for the antenna system to take full advantage of the spatial freedom of the antenna system.

大規模天線是具有大規模收發信機和大規模天線振子組成的天線陣列，其中，天線空間自由度遠大於8，如16、32、64、128，256，512等。這種情況下，通道狀態資訊測量的空間解析度直接取決於CSI-RS埠數量，即需要支援的CSI-RS埠數遠大於8。 A large-scale antenna is an antenna array composed of a large-scale transceiver and a large-scale antenna oscillator, wherein the antenna space degree of freedom is much larger than 8, such as 16, 32, 64, 128, 256, 512, and the like. In this case, the spatial resolution of the channel state information measurement is directly dependent on the number of CSI-RSs, that is, the number of CSI-RS parameters that need to be supported is much larger than 8.

通常大規模天線陣列是由水平維度的N h 和垂直維度N v 個天線振子與射頻器件組成N H ×N V 維自由度的平面形態的大規模有源天線陣列。當N h 8，並且N v 8時，可採用2套CSI-RS埠配置給一個UE，以確保UE可以測量天線系統的所有空間自由度。並且UE向基地台回饋一對CSIs。這一對CSIs中一個對應著大規模有源天線的一列N v 個天線埠，另外一個對應著大規模有源天線的一行N h 個天線埠。這2套CSI-RS埠可以配置在同一子訊框，也可以配置在不同子訊框。這2套CSI-RS埠分別測量垂直維度行通道(H v )和水平維度列通道(H h )。通過測量得垂直維度行通道(H v )和水平維度列通道H h 可以計算得到PMI，RI和CQI。 Generally, a large-scale antenna array is a large-scale active antenna array in a planar form of N H × N V dimensional degrees of freedom consisting of a horizontal dimension N h and a vertical dimension N v antenna elements and a radio frequency device. When N h 8, and N v At 8 o'clock, two sets of CSI-RS 埠 can be configured for one UE to ensure that the UE can measure all spatial degrees of freedom of the antenna system. And the UE returns a pair of CSIs to the base station. This corresponds to the CSIs in a massive one active antenna ports N v antennas, a further large-scale active antenna corresponds to a row of antenna ports N h. The two sets of CSI-RSs can be configured in the same sub-frame or in different sub-frames. The two sets of CSI-RS埠 measure the vertical dimension row channel ( H v ) and the horizontal dimension column channel ( H h ), respectively. PMI, RI and CQI can be calculated by measuring the vertical dimension row channel ( H v ) and the horizontal dimension column channel H h .

由於每套CSI-RS埠最大只能支持8個空間自由度，因此，當N h >8，或N v >8時，為了保證下行通道狀態資訊測量的空間解析度，可以引入新的下行參考信號埠，但這將會帶來顯著的時頻資源開銷。如果限制 下行參考信號埠數，又不能保證下行通道狀態資訊測量的空間解析度，從而無法發揮大規模(massive)MIMO的性能優勢。 Since each set of CSI-RS埠 can only support a maximum of 8 spatial degrees of freedom, when N h >8, or N v >8, a new downlink reference can be introduced to ensure the spatial resolution of downlink channel state information measurement. The signal is 埠, but this will bring significant time-frequency resource overhead. If the number of downlink reference signal parameters is limited, the spatial resolution of the downlink channel state information measurement cannot be guaranteed, and the performance advantage of massive MIMO cannot be exerted.
