本發明係有關無線網路中之無線電共存。
現代的無線裝置,比如手機、平板電腦、及其他可攜式計算裝置,時常包括多種類型的無線電以作通訊用。例如,智慧型電話可包括連接到細胞塔之4G收發器、連接到本地網際網路熱點的WiFi收發器、及連接到比如耳機或鍵盤之附近的裝置之藍芽收發器。WiFi收發器可在藍芽收發器傳送資訊的實質上相同時期接收資訊。在一些範例中,4G收發器可在藍芽收發器接收資訊的實質上相同時期傳送資訊。因此,共存干擾可能會發生於在智慧型電話中運作的WiFi收發器與藍芽收發器之間,或4G收發器與藍芽收
發器之間,藉此減少並置之收發器的每一個之通訊效用。

茲參考所繪示之示範實施例,並在本文中使用特定語
言來敘述示範實施例。儘管如此,應了解到不意圖對本發明之範疇作任何限制。
在揭露及敘述本發明前,應了解到本發明不限於本文揭露之特定結構、程序步驟、或材料,但延伸至在此相關技藝中具有通常知識者所理解的這些之等效者。也應了解到本文中所採用的術語係僅用於敘述特定實施例且不非意圖為限制性。
如本文中所用,詞語「實質上」係指一個動作、特性、性質、狀態、結構、物件、或結果之完全或幾乎完全的範圍或程度。例如,「實質上」被封閉之一個物體意指該物體完全被封閉或幾乎完全被封閉。自絕對完全性之確切可允許的偏離程度在一些情況中可取決於特定上下文。然而,一般而言,完全性的接近程度將會為使得整體結果就像獲得絕對及全然完全性時一般。「實質上」的使用,當用於負面含義來指一個動作、特性、性質、狀態、結構、物件、或結果之完全或幾乎完全缺乏時,也同樣適用。
可在此說明書之本體中的別處定義其他詞語。
於下提供技術實施例之初步概觀,且接著之後以更多細節敘述特定的技術實施例。此初步總結旨在幫助讀者更迅速了解該技術,且非意圖識別該技術的關鍵特徵或必要特徵,也非意在限制主張專利權之標的的範疇。
藍芽收發器時常與其他類型的無線電及/或收發器並置。例如,使用正交分頻多重存取(OFDMA)來通訊的收發器,比如第三世代合作夥伴計畫(3GPP)長期演進(LTE)收發器、電機電子工程師學會(IEEE)802.16收發器,常稱為WiMAX(全球互通微波存取),無線區域網路(WLAN)收發器(亦即,IEEE 802.11無線電,常稱為WiFi)、及/或全球導航衛星系統(GNNS)接收器。
每一個並置的無線電可用於一個特定的目的。例如,藍芽收發器可用來與無線私域網路(WPAN)通訊,WiFi收發器可用來與無線區域網路(WLAN)通訊、及3GPP LTE或WiMAX收發器可用來與無線廣域網路(WWAN)通訊。
與使用OFDMA通訊的其他類型的收發器(比如3GPP LTE收發器、WiMAX收發器、及/或WiFi收發器)並置之藍芽收發器在無線裝置(如智慧型電話或平板電腦)中之同時操作會產生減少收發器兩者之資料通量的干擾。在整個此說明書中提出並置之藍芽收發器及3GPP LTE收發器的多個範例。此並非意為限制性。相同的(諸)系統及(諸)方法可應用於與藍芽收發器並置之在時域雙工(TDD)中操作的其他類型之OFDMA無線電。
一般而言,TDD係指雙工通訊鏈結,其中藉由在相同頻帶中不同時間槽的分配將上鏈與下鏈分開。由於TDD允許上鏈和下鏈資料傳輸的不對稱流,將上鏈及下鏈傳輸的時間槽分配給使用者。TDD有利於上鏈及下鏈資料率有不對稱的情況。
藍芽接收可能會與來自3GPP LTE收發器的傳輸起衝突,尤其當收發器兩者並置於相同裝置上時,比如智慧型電話、平板電腦、上網本、膝上型電腦、或另一種類型的無線行動裝置。藍芽傳輸亦可降低3GPP LTE收發器中之接收的敏感度。
欲減少共存干擾,有若干種可能的解決方法。一個可能的解法為使用分頻多工(FDM)來移動來自一個收發器的信號在頻率上遠離另一個收發器的信號,藉此創造更多頻率分離。另一個可能的解法為使用分時多工(TDM),其中可使用排程,所以當一個收發器正在傳送時,另一個並置的收發器不會同時接收。
TDM的一個範例可包括間斷接收(DRX),其將於下以更多詳細討論。射頻解法涉及使用射頻濾波,其可用來減少越界(out-of-bounds;OOB)發射量,在發射器使用濾波器,或在接收器使用濾波器來阻擋越界信號。基於功率的解法可用來減少傳輸功率,藉此潛在減少干擾程度。藉由結合前述解法的兩個或更多者亦可有混合型解法。
針對3GPP LTE收發器及並置的藍芽收發器可界定重
複的時域傳輸/接收(Tx/Rx)型樣來協調其之傳送器與接收器。如果資料在時間上週期性地受到配置,則Tx/Rx型樣可以已知的間隔重複。已知的間隔允許在3GPP LTE收發器中做出持續的保留來減少或避免不同收發器間的干擾。
例如,重複的Tx/Rx型樣針對藍芽收發器所傳送的每一個延伸同步連結導向(eSCO)的封包界定一個特定的藍芽傳送時間槽來防止藍芽傳輸干擾3GPP LTE接收,並保護3GPP LTE傳輸不受藍芽接收的干擾。
使用持續保留來協調3GPP LTE與藍芽傳送器和接收器的能力亦使其他類型的收發器得以被並置。例如,可協調WiFi收發器來在3GPP LTE與藍芽收發器間所形成之協調中的特定時期通訊。
第1圖提供顯示針對操作於分時雙工(TDD)模式中之藍芽無線電的eSCO格式化封包102及針對3GPP LTE無線電的全部七種組態之Tx/Rx子訊框104的傳輸及接收。使用一槽藍芽eSCO封包作為範例來顯示本文中所呈現的圖及表。然而,此干擾避免技術可應用於其他藍芽輪廓及封包長度(例如三或五槽的封包)。藍芽eSCO封包可包括具有不同數量的傳送及接收時槽之各種不同的形式。針對單一槽eSCO封包,藍芽指明6、8、10、12、14、16、及18之間隔。在第1圖中所示的間隔為TeSCO=8,包含四個傳送時槽及四個接收時槽。藍芽亦指明重傳窗WeSCO為0、2、或4。重傳窗指明一藍芽封包在其間隔
內(TeSCO)可發生的嘗試傳送之數量。雖然本說明書目前限制重傳嘗試於0、2、或4個,當TeSCO等於或大於8時可包括額外的重傳嘗試。未來的藍芽標準可包括額外的重傳嘗試,且本文揭露之實施例不限於本標準中所述之0、2、或4個。
3GPP LTE標準,如本文中所用,可包括2008年第四季之3GPP LTE發行8、2011年第一季之3GPP LTE先進發行10、及2012年第三季之發行11。然而,本文中所揭露之實施例不限於這些發行。當使用相同的TDD組態和子訊框時序時,未來的標準亦可適用。根據這些3GPP LTE發行的至少一者運作之收發器在本文中亦稱為LTE收發器。術語3GPP、3GPP LTE、或LTE之使用非意為限制性。該些術語的任何者可指3GPP發行的任何者。
目前,3GPP LTE通訊界定七種不同的LTE TDD組態。第1圖提供每一個LTE組態之範例,予以標號為0至6。每一種組態在針對每一種組態之接收子訊框的較長連續數量的一開始106對準。同步化藍芽封包,使第一接收時槽(時槽1)與這七個LTE組態之每一個中的連續接收子訊框的第一接收子訊框對準。
如第1圖中所示,藍芽時槽102具有與LTE子訊框不同的時間週期。藍芽時槽各有0.625毫秒(ms)之週期,而每一個LTE訊框有10ms之訊框期間。每一個LTE訊框由10個子訊框構成。因此,每一個子訊框具有1ms的期間。因此,即使同步化了藍芽封包而使傳送槽0
與每一個LTE TDD組態中之一傳送子訊框對準,且接收槽1與每一個組態的連續接收子訊框中之第一接收子訊框對準,傳送及接收槽很快會變成不對準,使得來自藍芽及3GPP收發器之傳輸和接收會造成收發器的每一者中之同頻干擾。
同頻干擾可能會在收發器之一於另一個收發器的接收間隔中傳送時發生。這在3GPP LTE收發器於藍芽收發器的接收時期中傳送時尤其如此,因為3GPP LTE收發器以顯著較高的功率傳送並因此可能會在功率上壓過(或衝突)藍芽收發器正嘗試於藍芽接收時期中接收之大部分的藍芽信號。
第2圖為繪示根據一個範例之長間斷接收(DRX)循環之圖。在3GPP LTE發行8中引進DRX的概念以節省功率。DRX可用於使無線裝置,比如3GPP LTE網路中之使用者裝置(UE),間斷地監測控制通道,比如從比如增進型節點(eNB或eNodeB)之傳輸站傳送的實體下鏈控制通道(PDCCH)。藉由使用DRX的間斷監測可在UE提供顯著的功率節省,因為可針對選定時期關閉在UE的接收器。將於下更完整解釋使用DRX的3GPP LTE收發器之排程。
根據本發明之一實施例,除了節省功率,DRX亦可用來提供TDM解決方法以減少並置裝置之共存干擾。例如,使用DRX可減少並置之3GPP LTE收發器與低功率藍芽(BT)收發器之間的共存干擾,藉由排程BT收發器
在LTE收發器無接收時傳送。
在一實施例中,多重無線電裝置中之一個收發器(如LTE收發器)可藉由減少收發器監測控制通道(比如實體下鏈控制通道(PDCCH))的時間量而組態成更常被關閉。換言之,該收發器可與一個傳輸站(稱為網路節點)通訊以協商收發器將會從網路節點接收通訊的時期。在無接收資訊之已協商時期中,收發器可關閉其之接收器並進入低功率狀態。在若干不同的無線通訊標準中使用DRX,包括但不限於3GPP LTE發行8、9、10、及11。
如果針對DRX組態3GPP LTE收發器且其處於RRC_CONNECTED模式中,則3GPP LTE收發器可操作成間斷地監測。否則,未針對DRX組態之3GPP LTE收發器可持續監測PDCCH。可藉由組態參數onDurationTimer、drx-InactivityTimer、longDRX-Cycle、drxStartOffset、及非必要之drxShortCycleTimer和shortDRX-Cycle而將無線電資源控制(RRC)用來控制3GPP LTE收發器中之DRX操作。當未組態短DRX循環時,3GPP LTE收發器在longDRX-Cycle參數的一開始(根據onDurationTimer中所界定之長度)監測PDCCH。如果可完成下鏈及/或上鏈傳輸,則在onDuration-Timer後3GPP LTE收發器可停止監測PDCCH。在剩餘的DRX循環(例如短DR循環)中,3GPP LTE收發器可變成非現行。在此期間,eNB不排程下鏈傳輸且eNB也不會要求3GPP LTE收發器傳送上鏈資料。當組態短DRX循環時,短DRX循環可視為當封
包晚到時之確認時期,在3GPP LTE收發器進入長DRX循環前。當3GPP LTE收發器正處於短DRX循環中的同時資料抵達eNB時,則資料排程為在下一次喚醒時間傳送,在其之後3GPP LTE收發器繼續持續接收。另一方面,如果在短DRX循環期間沒有資料抵達eNB,則如果當下封包活動結束的話3GPP LTE收發器可進入長DRX循環。DRX活動時間為3GPP LTE收發器於DRX循環內監測PDCCH時的期間。
回到第2圖,顯示一示範長DRX循環。長DRX循環可包括啟通(ON)期間及關閉(OFF)期間。於長DRX循環之ON時期(亦即排程時期)中,eNB可與UE排程傳輸。於長DRX循環之OFF時期(亦即無排程時期)中,eNB不與UE排程傳輸。一般而言,UE可在一計時器期滿時從非必要的短DRX循環過渡到長DRX循環。
第3A及3B圖繪示根據一範例支援DRX型樣的示範TDD組態310及320。使用DRX解決方法來減少多重無線電裝置中之共存干擾的一個限制在於目前支援的長DRX循環值不包括可用來顯著改善裝置中(in-device)共存情節的數個值。例如,不允許可用來減少在LTE及藍芽情節(例如LTE收發器與藍芽收發器傳送/接收資訊實質上同時地傳送/接收資訊)中之裝置中干擾的長DRX循環值。這些長DRX循環值可包括2毫秒(ms)、5ms、及/或8ms。將於下更詳細討論,2ms、5ms、及8ms長DRX循環值可提供一或更多有用的混合自動重複請求
(HARQ)程序保留型樣。
使用DRX來減少在LTE及藍芽情節中之共存干擾的一個限制為當LTE ON期間時期未延長時,DRX支援單一DRX循環內的相連LTE下鏈(DL)子訊框。使用目前可得之DRX循環值,當針對LTE及藍芽情節使用DRX解決方法時,DRX循環為10ms。另外,可在10ms長DRX循環內使用5ms短DRX循環。因此,DRX可支援具有在10ms週期或5ms週期中為相連的LTE ON下鏈子訊框之位圖型樣。
第3A圖繪示具有可用來減少多重無線電裝置中之裝置中干擾的循環時間之DRX型樣的一個範例。尤其,顯示包括2ms長DRX循環對於LTE及藍芽情節的好處。示範組態310為TDD組態2。組態310包括m個訊框,且具有2ms之循環起始偏移。組態310之總長度為10ms長,且每一個子訊框為1ms長。另外,可由位圖0111010111表示組態310。換言之,「0」意指子訊框不可被使用(例如子訊框被關閉),及「1」意指子訊框可被使用。在此,被關閉的子訊框為0、4、及6,因此導致0111010111之位圖。在組態310中之子訊框可為下鏈(DL)子訊框或上鏈(UL)子訊框。在此,DL子訊框為灰色且UL子訊框為白色。根據TDD組態2(其為七個可得的TDD組態之一),子訊框0、1、3、4、5、6、8、及9為DL子訊框且子訊框2及7為上鏈子訊框。另外,針對有關於LTE及藍芽情節之DRX型樣,一般忽略上鏈子
訊框。因此,子訊框0、4、及6為關閉,且子訊框2及7為上鏈,導致子訊框1、3、5、8、及9。換言之,子訊框1、3、5、8、及9為LTE ON子訊框,並由格紋子訊框表示。
因此,2ms長DRX循環值對組態310有利,可允許支援更多HARQ位圖型樣。第1個子訊框係包括在第一個2ms循環中;第3個子訊框係包括在第二個2ms循環中;第5個子訊框係包括在第三個2ms循環中;且第8個及第9個子訊框兩者都包括在第五個2ms循環中。子訊框6或7都沒有包括在第四個2ms循環中,因為子訊框6為OFF而子訊框7為上鏈子訊框。子訊框8被視為onDuration,因為onDurationTimer的單位為一個PDCCH子訊框,其在TDD情況中為DL子訊框。因此,onDurationTimer在子訊框7開始,但因為子框7為UL子訊框,其延伸至子訊框8。因此,子訊框被視為ON。如果不支援2ms長DRX循環,則會需要使用另一個HARQ位圖型樣,其會使可被LTE使用之子訊框變得較少。
第3B圖繪示具有可用來減少多重無線電裝置中之裝置中干擾的循環時間之另一個DRX型樣的一個範例。尤其,顯示包括5ms長DRX循環對於LTE及藍芽情節的好處。尤其,使用5ms長DRX循環允許使用額外的HARQ位圖型樣。若無法使用5ms長DRX循環,可使用的LTE子訊框較少。
示範組態320為TDD組態2。組態320包括m個訊
框,且具有5ms之循環起始偏移。另外,可由位圖0111101111表示組態320。在此,關閉的子訊框為0和5,因此導致0111010111的位圖。根據TDD組態2(其為七個可得的TDD組態之一),子訊框0、1、3、4、5、6、8、及9為DL子訊框且子訊框2及7為上鏈子訊框。
當考慮有關於LTE及藍芽情節之DRX型樣時一般會忽略上鏈子訊框(亦即,子訊框2和7),且子訊框0及5為關閉,結果為子訊框1、3、4、6、8、及9。換言之,子訊框1、3、4、6、8、及9為被3GPP LTE收發器接收之LTE ON下鏈子訊框。因此,5ms長DRX循環值對組態320有利。子訊框1、3、及4係包括在第一個5ms循環中,且子訊框6、8、及9係包括在第二個5ms循環中。10ms長DRX循環值無法與TDD組態2一起使用,因為子訊框5為關閉。
在LTE及藍芽情節中,2ms及5ms長DRX循環值可提供有用的HARQ程序保留型樣給分時雙工(TDD)。一般而言,HARQ可用來確保資料從一個節點可靠地被發送到另一個節點。HARQ使用停止並等待協定。一傳送實體(如LTE收發器)傳送資料區塊至一接收實體(如eNB)。傳送實體停止並等待直到其從接收實體接收到確認(ACK)或負確認(NACK)。如果傳送實體接收到ACK,則傳送下一個資料區塊。如果傳送實體接收到NACK,則可重傳相同的資料區塊。無論接收到ACK或NACK,傳送實體於特定時期內排程並處理待傳送的下一
個資料區塊。在LTE中,可使用N程序停止並等待,其中傳送實體停止並等待一個特定的HARQ程序。例如,傳輸可停止並等待一個特定的HARQ程序。然而,有多個HARQ程序,所以從傳送器角度來看,其不會停止其之傳輸。
一般而言,LTE使用在時間上偏移的多個HARQ平行程序。由於每一個程序傳送一個區塊的資料,在下一個傳輸配置抵達時,傳送實體會已經從接收實體接收到ACK或NACK,並因此產生待傳送或待重傳之下一個資料區塊。因此,從傳送實體的角度來看,會不斷地傳送資料到接收實體。在TDD中,支援可組態數量之HARQ程序。
藉由施加2ms及5ms長DRX循環值到LTE及藍芽情節,創造出2ms及5ms型樣。這些2ms及5ms型樣可被視為HARQ相容型樣。一個型樣如果:(1)針對DL或UL HARQ程序經致能的每一個LTE DL子訊框與至少一個LTE UL子訊框關聯;及(2)針對DL或UL HARQ程序經致能的每一個LTE UL子訊框與至少一個LTE DL子訊框關聯;及(3)至少一個LTE DL HARQ程序與一個UL HARQ程序為致能,則與HARQ相容。在TDD組態2中,有192個HARQ相容的型樣,及當施加DRX到LTE及藍芽情節時所支援的51個HARQ相容的型樣。因此,施加DRX到LTE及藍芽情節時所支援的HARQ相容型樣的比例為27%。另外,2ms及5ms長DRX循環值支援額外的HARQ位圖型樣。若不使用2ms及5ms長
DRX循環值,則HARQ位圖型樣會使用較少數量的LTE子訊框。換言之,位圖會包括指示特定子訊框無法被使用的額外「0」。
提供至少一個HARQ程序保留型樣確保UE的每一個無線電收發器不會在UE之一個不同的無線電收發器正在接收/傳送資訊的同時傳送/接收資訊。因此,可減少UE中之複數無線電收發器之間的共存干擾。另外,每一個無線電收發器可包括一個不同的無線電存取技術(RAT)。RAT的範例包括3GPP LTE、WiMAX、藍芽、WLAN、GNSS、等等。
第3C圖為顯示根據一範例之LTE傳送/接收型樣和藍芽傳送/接收型樣之時序圖330。LTE Rx型樣及LTE Tx型樣相同。每一個ON及OFF循環維持2ms。因此,LTE Rx及LTE Tx的位圖為11001100。每一個數字指示在一秒的時期中LTE是否為ON(如「1」)或0FF(如「0」)。因此,「11」指示兩秒的ON週期,且「00」指示兩秒的OFF週期。如時序圖330所示,LTE傳輸與藍芽接收之間無干擾。換言之,在LTE正在傳送(亦即,LTE Tx ON)的時間中,藍芽不接收。同樣地,在藍芽正在接收(亦即,BT Rx ON)的時間中,LTE不傳送。雖然在LTE接收及藍芽傳送之間有一些重疊,一般來說不會有重疊所致之干擾。假設為藍芽傳輸不會干擾LTE接收,因為LTE下鏈頻帶不與藍芽傳輸頻帶重疊。
時序圖330有關於在分頻雙工(FDD)中運作的
LTE。在FDD中,在傳輸側和接收側使用不同的頻帶。由於FDD使用不同頻帶來發送及接收資訊,發送及接收資料信號不會互相干擾。
時序圖330為針對LTE與藍芽間的共存之位圖為基的TDM解決方法。具有8ms的位圖(如11001100)可確保LTE不會在藍芽接收資訊的實質上同時傳送資訊。因此,具有8ms的長DRX循環(其相應於8ms長之位圖)可對LTE FDD有用處。在一些範例中,具有4ms的長DRX循環可對LTE FDD有用處,但不像8ms的長DRX循環,4ms的長DRX循環沒有利用到LTE FDD中之HARQ程序保留型樣。換言之,可遮蔽數個LTE FDDHARQ程序以因應LTE與藍芽之間的共存。針對FDD,有8個上鏈HARQ程序,而下鏈可具有多達8個HARQ程序。可以任何順序傳送下鏈HARQ程序而無固定的時序,而每一個上鏈HARQ程序被分配到一個特定的子訊框。UE每八個子訊框在相同的HARQ程序內傳送。因此,8ms的長DRX循環對減少LTE與藍芽之間的共存干擾有用,因為8ms的長DRX循環相應於FDD中可得知8個上鏈及下鏈HARQ程序。
第4圖繪示根據一範例之DRX組態資訊之ASN.1碼範例。抽象語法記法1(ASN.1)可用來實施對現有DRX組態的增進。DRX-Config-r11(亦即,DRX組態11)用來界定DRX循環的各種特性。現有的DRX-Config-r11包括ASN.1碼來界定onDurationTimer、drx-InactivityTimer、
drx-RetransmissionTimer、longDRX-CycleStartOffset、shortDRX-cycle、及drxShortCycleTimer。目前,longDRX-CycleStartOffset包括sf10、sf20、sf32、sf40等等的循環值。藉由添加sf2、sf5、及sf8之循環值到ASN.1碼中可將2ms、5ms、及8ms長DRX循環值之添加包括在DRX-Config-r11中。由於現有的DRX-Config-r11不允許擴充,新的DRX-Config-r11可組態有2ms、5ms、及8ms長DRX循環值來提供可用於減少多重無線電裝置中之裝置中干擾的額外DRX型樣,如先前段落中所討論。
第5圖繪示根據一範例在長DRX循環期間用來接收下鏈參考資源510的子訊框。下鏈參考資源510可包括從eNB傳送的參考信號(RS)。在UE之參考信號的經測量功率用來判定eNB傳送下鏈資料之功率。可經由通道狀態資訊(CSI)報告傳送參考信號的經測量功率到eNB。
在無線通訊中,CSI可指一通訊鏈結的已知通道性質。CSI描述一信號如何從傳送器傳播到接收器。另外,CSI可代表散射、衰退等等之結合效應。CSI確保傳輸係調適於當前的通道情況,藉此導致藍芽收發器、LTE收發器等等之可靠通訊。從UE週期性傳送CSI到eNB。
一般而言,CSI可包括通道品質指標(CQI)、預編碼矩陣指標(PMI)、及階級指標(RI)的至少一者。CQI為UE發信至eNB以指示下鏈傳輸的適當資料率之資訊。CQI可基於接收下鏈信號對干擾加雜訊比(SINR)之
測量,以及UE接收器的各種已知特性。PMI為UE所回饋之信號,且相應於預編碼器之索引,其最大化可跨下鏈空間傳輸層接收到之資料位元的總數。RI係由針對實體下鏈共享通道(PDSCH)所組態的UE發信到eNB。RI相應於針對空間多工之有用的傳輸層之數量(基於UE的下鏈通道之估計)。
通常在下鏈參考資源510的至少四個符號後傳送CSI報告。為了使參考信號的測量準確,應在具有最小干擾的下鏈子訊框中接收參考信號。干擾可減少參考信號測量的準確度並衝擊CSI報告的準確度。據此,選擇下鏈子訊框來接收具有很少干擾之參考信號很重要。
目前,選擇下鏈參考資源510之下鏈子訊框的規則不考慮裝置中干擾的衝擊。因此,當有裝置中干擾時(例如藍芽收發器與LTE收發器正在接收參考信號的實質上同時傳送資訊),在下鏈參考資源510符號中接收到的參考信號之測量可能會受到負面衝擊。
如第5圖中所示,LTE(或WWAN)收發器的長DRX循環可分成排程時期和無排程時期。當從LTE無排程時期過渡到LTE排程時期時,可將UE組態成發送CSI(如CQI、PMI、及RI)到eNB。換言之,可將在UE中之LTE收發器組態成傳送CSI到eNB。CSI可基於在下鏈參考資源510接收到的參考信號。可由下鏈子訊框n-nCQI_ref界定下鏈參考資源510(亦即,時域參考)。
CSI通報子訊框520發生在下鏈子訊框n-nCQI_ref的至
少四個子訊框後。換言之,在上鏈子訊框週期性通報CSI至eNB,且上鏈子訊框發生在從eNB接收到下鏈參考資源510的至少四個子訊框後。因此,CSI通報子訊框520位在UE中之收發器(如WWAN收發器)的一個長DRX循環後並與下鏈參考資源510(亦即,下鏈子訊框n-nCQI_ref)相應。在一些範例中,在下鏈子訊框n-nCQI_ref的超過四個子訊框(如六個子訊框)後通報CSI。
當使用DRX作為TDM解決方法時,CSI測量需要特別處置。否則,下鏈參考資源510會受到多重無線電裝置中之並置收發器間的裝置中干擾的衝擊,從而導致UE通報不準確的CSI。不準確的CSI可能會實質上減少系統通量。換言之,在一通訊通道上之成功訊息傳遞的平均率可能會因為不準確的CSI而減少。因此,下鏈參考資源510不應受到裝置中干擾的衝擊。
如果下鏈子訊框n-nCQI_ref不被裝置中干擾所干擾的話,下鏈子訊框n-nCQI_ref可被視為有效。因此,如果UE於一時期(其不相應於在UE中之一個不同的共存無線電收發器傳送上鏈子訊框)中從eNB在下鏈子訊框中接收參考信號或其他類型的下鏈參考資源,則該下鏈子訊框不受到裝置中干擾的衝擊。換言之,當裝置中干擾當下存在的同時,在UE不從eNB接收下鏈子訊框n-nCQI_ref。因此,下鏈子訊框n-nCQI_ref為有效並可用於接收下鏈參考資源。
在一些範例中,eNB可能會將下鏈子訊框n-nCQI_ref
分配成在UE中的一個不同的收發器(如藍芽收發器)正在傳送資訊的同時於一子訊框中由UE接收(如UE中的LTE收發器)。如果知道這會發生的話,則可將下鏈子訊框n-nCQI_ref指定成無效並無法用來接收來自eNB的參考符號。換言之,如果與下鏈參考資源510關聯的下鏈子訊框被裝置中干擾所干擾的話,可將下鏈參考資源510識別成無法被使用。
在一些範例中,為了減少下鏈子訊框中的裝置中干擾的機會,如果下鏈子訊框屬於長DRX循環之無排程時期的話,如第5圖中所示,則可將該下鏈子訊框指定為無效。指定為無效的子訊框將不會被eNB用來傳送資料到UE。因此,如果將DRX解決方法用於裝置中共存,則可在不包括於長DRX循環的無排程時期中的下鏈子訊框中接收下鏈參考資源510。在一實施例中,包括在長DRX循環之排程時期中的下鏈子訊框可被指定為有效子訊框以供UE用來接收下鏈參考資源,比如RS。另外,在無排程時期中的子訊框可被UE用來通報基於參考資源之CSI到eNB。
在一實施例中,如果:(1)將下鏈子訊框組態成針對UE之下鏈子訊框;(2)下鏈子訊框不包括多媒體廣播單頻網路(MBSFN)子訊框(除了傳輸模式9以外);(3)下鏈子訊框不含有下鏈引導時間槽(DwPTS)欄位,以防止DwPTS的長度為7680.Ts或更少的情況發生;(4)下鏈子訊框不落在UE之經組態的測量間隙
內;(5)下鏈子訊框,針對週期性CSI通報,當UE組態有CSI子訊框組時,為鏈結至週期性CSI報告的CSI子訊框組之一個元素;及(6)下鏈子訊框不被裝置中干擾所干擾,則可視下鏈子訊框n-nCQI_ref為有效。另外,正當使用DRX來減少裝置中共存時,如果下鏈子訊框並非為無排程時期的一部分,則可視下鏈子訊框n-nCQI_ref為有效。
在本發明的一些實施例中,無線電鏈結監測(RLM),由UE之WWAN收發器所履行,可使用實質上沒有來自UE中之複數個共存無線電收發器的裝置中干擾的子訊框。UE中之RLM功能係用來監測在RRC_CONNECTED狀態中的服務細胞之下鏈無線電鏈結品質。RLM係基於細胞特定的參考信號。因此,在RRC_CONNECTED狀態中的UE可判定其是否與服務細胞同步或不同步。在特定數量的連續不同步指示(稱為「N310」)的情況中,UE可啟動網路組態的無線電鏈結失敗計時器「T310」。如果由UE的實體層通報數個連續的同步指示「N311」,則停止該計時器。不同步和同步計數器(N310及N311)兩者都可由網路組態。在計時器T310期滿時,發生無線電鏈結失敗(RLF)。結果為UE關閉其傳送器以避免干擾並接著要求重新建立RRC連結。
當受到裝置中干擾衝擊之子訊框用於RLM時,干擾會造成測量細胞特定之參考信號時的錯誤。例如,在長
DRX循環的無排程時期中,其他RAT(例如WLAN、藍芽)可傳送資訊。因此,在UE中之藍芽收發器可在與LTE收發器正在接收資訊(比如細胞特定的參考信號)的實質上相同子訊框傳送資訊。如果接收到多個錯誤,UE可通報無線電鏈結失敗,關閉WWAN傳送器,並進行RRC連結的重新建立。這會導致較少的通量及3GPP網路之不必要的管理負擔。
在一些範例中,可將UE之WWAN無線電收發器組態成在長DRX循環之排程時期中發生的下鏈子訊框中接收RLM,從而減少使用受裝置中干擾衝擊的子訊框來履行RLM的可能性。因此,當UE正在履行RLM的同時,UE不使用受到裝置中干擾衝擊的子訊框。另外,在長DRX循環的無排程時期中,UE可判定哪些子訊框不受到裝置中干擾的干擾。UE可使用不受裝置中干擾所干擾的子訊框來履行RLM。
在另一個實施例中,揭露一種在多重無線電裝置中減少共存干擾的方法600,如第6圖的流程圖中所繪示。該方法包括在多重無線電裝置從增進型節點B(eNodeB)接收610間斷接收(DRX)組態之操作。該多重無線電裝置可為具有複數無線電收發器的使用者裝置。方法600進一步包含施加620該間斷接收(DRX)組態至該多重無線電裝置中之該些複數個無線電收發器的至少一者。該DRX可包括該些複數個無線電收發器的該至少一者之長DRX循環。該方法600進一步包含針對該長DRX循環選擇2
毫秒(ms)、5ms、及8ms循環起始偏移週期之一以減少該多重無線電裝置中之該些複數個無線電收發器之間的共存干擾。
在一實施例中,該方法600中的該些複數個無線電收發器包含第三世代合作夥伴計畫長期演進(3GPP LTE)無線電收發器及藍芽無線電收發器。
在一實施例中,在該方法600中的該2ms循環起始偏移週期提供至少一個HARQ保留型樣以減少該藍芽無線電收發器及在LTE分時雙工(LTE-TDD)中通訊之LTE無線電收發器之間的該共存干擾。另外,在該方法600中的該5ms循環起始偏移週期提供至少一個HARQ保留型樣以減少該藍芽無線電收發器及在LTE分時雙工(LTE-TDD)中通訊之LTE無線電收發器之間的該共存干擾。此外,在該方法600中的該8ms循環起始偏移週期提供至少一個HARQ保留型樣以減少該藍芽無線電收發器及在LTE分頻雙工(LTE-FDD)中通訊之LTE無線電收發器之間的該共存干擾。另外,該方法600可包括藉由該UE,在該長DRX循環期間監測實體下鏈控制通道(PDCCH)。
在一實施例中,在該方法600中之選擇該些複數個循環起始偏移週期之一的操作可包括提供至少一個HARQ程序保留型樣,以確保該UE的該些複數個無線電收發器之每一個在當該UE的一不同之無線電收發器正在接收/傳送資訊的同時不傳送/接收資訊,藉此減少該UE中的該些複
數個無線電收發器之間的共存干擾,其中每一個無線電收發器包括一不同的無線電存取技術(RAT)。
在另一個實施例中,揭露一種無線電共存系統700。第7圖繪示系統700之一示範區塊圖。系統700包含間斷接收(DRX)模組710,其可操作成施加DRX至具有複數個共存的無線電收發器之使用者裝置(UE)中的無線廣域網路(WWAN)收發器。一通道狀態資訊(CSI)通報模組720係組態成,從該UE至該eNB,在CSI通報子訊框,週期性通報該CSI。該CSI通報子訊框位在該UE中的WWAN收發器之長DRX循環之後。一參考資源子訊框選擇模組730係組態成相較於CSI通報子訊框的位置選擇下鏈參考資源子訊框,使得在實質上沒有來自該UE中之該些複數個共存無線電收發器的裝置中干擾下接收該下鏈參考資源子訊框。一無線電鏈結監測(RLM)模組740係組態成使用實質上沒有來自該UE中的複數個共存無線電收發器之裝置中干擾的WWAN接收器之子訊框來履行無線電鏈結監測(RLM)。可在該長DRX循環的該排程時期中於UE的WWAN無線電收發器上履行該RLM。系統700可包括藍芽無線電702、3GPP LTE無線電704、及一並置的無線電706。雖然DRX模組、CSI通報模組、參考資源子訊框選擇模組、及RLM模組繪示成位在行動通訊裝置中的無線電外部,這些模組亦可整合在無線電之一或更多者內。
在一實施例中,該些複數個共存無線電收發器可包括
至少兩個無線電存取技術(RAT),該RAT包含:3GPP LTE無線電收發器、無線區域存取網路(WLAN)收發器、藍芽收發器、及全球導航衛星系統(GNSS)接收器。
在一實施例中,該下鏈參考資源子訊框包括CSI參考資源。
在本揭露的一些實施例中,通報到該eNB之該CSI不會因來自該UE中之該些複數個共存無線電收發器的裝置中干擾之緣故而實質上減少UE通量。此外,該CSI包含通道品質指標(CQI)、預編碼矩陣指標(PMI)、及階級指標(RI)之至少一者。
在一些實施例中,該CSI通報模組720進一步組態成,從該UE至該eNB,在從無排程時期至排程時期的過渡期中,通報該CSI,其中該無排程時期及該排程時期在該3GPP LTE無線電收發器的長DRX循環期間發生。另外,該CSI通報模組720進一步組態成在上鏈子訊框週期性通報該CSI至該eNB,其中該上鏈子訊框在從該eNB接收該下鏈參考資源子訊框後的至少四個子訊框發生。此外,該CSI通報模組720進一步組態成,在該UE從該eNB,於不相應於在UE中正傳送上鏈子訊框的一不同共存無線電收發器的時期中接收該下鏈參考資源子訊框。在一些範例中,該CSI通報模組720進一步組態成,在該UE從該eNB,於該長DRX循環的排程時期中,接收該下鏈參考資源子訊框。
在本揭露的一些實施例中,系統700可包括無線電鏈結監測(RLM)模組740,其係組態成使用實質上沒有來自該UE中的複數個共存無線電收發器之裝置中干擾的3GPP LTE無線電收發器之下鏈子訊框來RLM。另外,RLM模組740進一步組態成在該DRX的長DRX循環之排程時期中在該UE的3GPP LTE無線電收發器上履行該RLM。RLM模組可判定具有在長DRX循環之無排程時期中實質上無裝置中干擾的子訊框;並使用具有在長DRX循環之無排程時期中實質上無裝置中干擾的子訊框來履行RLM。
