Description

1246839 ⑴ 玖、發明說明 (發明說明應敘明：發明所屬之技術領域、先前技術、内容、實施方式及圖式簡單說明) 技術領域 本發明係關於無線通信。具體而言，本發明係關於為高 速下行鏈路封包（HSDP)提供已偏壓的二進位決定。 先前技術 在HSDP HSDPA以及許多其他的通信系統中，有的應用需 要二進位元決定，但其中錯誤的懲罰在二決定之間是不等 的。 例如，HSDPA使用一 ACK/NACK信號，其中使用者設備（user equipment ; UE)可指示所發送的一資料區塊是否已成功解 碼。已發現：將NACK訊息錯誤地解釋為ACK較將ACK訊息 錯誤地解碼為NACK對系統效能損害更大。在後一種情形 下，錯誤將導致所發送的區塊進行不必要地重新發送，這 只不過相當於效率的較小損失。在前一種情形下，發送器 將假定先前所發送的區塊已成功發送，不再進行重新發送。 此種災難性故障會引起嚴重的系統崩潰。 已發現數種明顯的技術可施加偏壓於應答，以便識別 NACK之條件。例如，在二進位相移键控（binary phase shift keying ; BPSK)之正常固有的解調變中，輸出信號通常加以 標準化，如代表1的理想信號為+1.0，而代表0的理想信號則 為-1.0，且在具有損失、干擾和雜訊的典型通道中，標準化 輸出可能採用兩者之間的任何值。 在未施加偏壓的決定中，若一輸出z> 0，則該程序便宣告 1 ;若該輸出z<0，則該程序便宣告該輸出=0。在施加偏壓 (2) 1246839
否則宣告0。X視為臨 的決定中5若該輸出z>X 5則宣告i 界值，並根據分析來選擇。若希望輸出為1，則X將為負， 例如一較小的負數，如一〇 J等。 使用上述程序來使輸出標準化，並得出最佳臨界值，實 施起來是棘手且複雜的，且實施中的公差會起降級。 發明内容
根據本發明，可利用一標準以使該決定在應用中簡單且 可靠甚多，該標準明顯比簡單的X臨界值更加
^ 与F 根據此標準，對於時間劃分雙工（TDD)而言，該標準係以 所測量的信號干擾比（SIR)為基礎，該信號干擾比係源自通 項:估測私序。可見實際上所有的錯誤實例都發生在SIR值較 低時。 無線電調變（RM)解碼器的故 ^元錯誤之間的相關性較高； 度可靠性，且易於實施。 障或近似故障與傳輸中其他 因此，本發明之標準具有高 固1又吊式係用以實施本發明之 Μ r , r ^ χ 夂技術。在圖中所示的下行 連路軏例中，諸如基地台（BS1〇)< ^ ^ ^ ㈤的裝置以來自UE12的通 。（v驟S1)為基礎，利用此通信庐 产止 &件通道估測值（步騾S2)。 在v騾S3處，BS10使用廣為人知 ^ " 的技術自該通道估測值 侍出—信號干擾比（SIR)。在步驟S4 所班彡曰 處’ B S 10將在步驟S 3處 所獍件的SIR與一既定的臨界值比較。 該臨界值可藉由採用多種不同
Ab - m 術之一予以決定。一種 匕使用的技術為：藉由借助類比、γ ^ <分析及使用測試裝置 1246839
(實際測試的結合來決定。測試信號及雜訊係輸入至測試 裝置’並檢查輸出信號。測量輸出信號，並決定二進位決 足的正確性。對整個範圍的有用信號（包括極低信號）重複進 行測試。對於每個振幅位準，均儲存正確決定和不正確決 足的實例數目。一般而言，強信號與正確決定的極高頻率 有關’而弱信號則與不正確信號的高實例有關。該臨界值 取好係大於早獨雜訊的位準。 因為目的是避免特定類型的錯誤，如發送Nack時，宣告 ACK的可能性’故選擇（即施加偏壓於）該臨界值，從而當信 號南於该fe界值時，有可接受之較低頻率的錯誤發生，而 當#號低於孩臨界值時，有不可接受之頻率的錯誤發生。 因為目的是避免ACK的虛假宣告，故與低於該臨界值之信 號一起發生的任何決定均宣告為NACK。具體而言，當信號 低於咸臨界值時，二進位決定係施加偏壓，使最低災難性 結果減至最低（即使在錯誤中）。此技術如步騾S11所示，可 也由BS 10(或UE12)來離線或周期性實施。同樣地，必要時可 使用其他技術來獲得一臨界值。 若SIR小於汶^界值，則在步驟S5處，bsi〇將一 信號 發送至UEi2。在步騾S6處，_2接收並偵測該nack信號， 且在步驟S7處重新發送暫時儲存的通信，其係在步騾S8處 由BS10所接收。 返回步騾S4 ’假疋SIR大於該臨界值，該常式分支到步騾 S9，以發迗一 ACKh號。在步騾si〇處，蘭2接收八⑶信號， 並清除步騾S1所暫時儲存的通信。 1246839
應暸解，圖1所示的常式可等效地應用於上行鍵路，其中 BS10及UE12所執行的功能反向，且在步騾si發送及暫時儲 存通信的是BS10。UE12在步騾S2處獲得通道估測值，在步 騾S3處獲得SIR，在步騾S4將所衍生的SIR與一既定的臨界值 比較，且在步騾S5將NACK發送至BS。BS10分別在步騾S6及 S7處接收NACK並發送所暫時儲存的通信，重新發送的通信 在步騾S8處由UE12接收。若SIR係大於該臨界值，則UE在步 騾S9發送一 ACK條件（其在步騾si〇由BS10接收），從而該ACK 信號使該B S 10清除所暫時儲存的通信。 應暸解，本發明之技術亦可同時用於使用者設備與基地 台之間的上行鏈路及下行鏈路通信。 圖式簡單說明 圖1係概略性說明實施本發明之新穎方法的裝置。 圖式代表符號說明 BS 10 基地台 UE12 使用者設備
