預期一強化專用頻道資料傳輸排程之有效媒體存取控制架構。An effective media access control architecture that enhances the scheduling of dedicated channel data transmissions is expected.

本發明係有關經強化專用頻道排程傳輸方法及裝置。排程功率係針對排程資料流被計算。剩餘傳輸功率係針對強化專用頻道傳輸被計算。速率要求訊息係被產生，其中排程功率，剩 餘傳輸功率及速率要求訊息係被用來選擇傳輸格式組合(TFCs)及多工被排程用於強化專用頻道傳輸之資料。剩餘傳輸功率係藉由從最大允許功率擷取專用實體資料頻道(DPDCH)，專用實體控制頻道(DPCCH)，高速專用實體控制頻道(HS-DPCCH)，強化上鏈專用實體控制頻道(E-DPCCH)之功率及功率容限被扣除來計算。The invention relates to an enhanced dedicated channel scheduling method and apparatus. The scheduling power is calculated for the scheduled data stream. The remaining transmission power is calculated for enhanced dedicated channel transmission. Rate request message is generated, where the scheduling power is left The remaining transmission power and rate requirements messages are used to select Transport Format Combinations (TFCs) and multiplexed scheduling to enhance the transmission of dedicated channel transmissions. The remaining transmission power is enhanced by extracting the dedicated physical data channel (DPDCH), the dedicated entity control channel (DPCCH), the high-speed dedicated entity control channel (HS-DPCCH), and the uplink dedicated entity control channel (E-DPCCH) from the maximum allowable power. The power and power margin are deducted to calculate.

此後，”媒體存取控制-e”名詞將被共同用來參考媒體存取控制-e及媒體存取控制-es。Thereafter, the "Media Access Control -e" noun will be used jointly to refer to Media Access Control - e and Media Access Control - es.

本發明特性可被併入積體電路(IC)或被配置於包含多互連組件中之電路中。Features of the invention may be incorporated into an integrated circuit (IC) or configured in a circuit comprising multiple interconnected components.

第2圖顯示依據本發明被配置之無線傳送/接收單元媒體存取控制-e架構200。無線傳送/接收單元媒體存取控制-e架構200係包含一排程許可處理單元210，一剩餘傳輸功率計算單元215及一速率要求處理單元220。Figure 2 shows a wireless transmit/receive unit media access control-e architecture 200 configured in accordance with the present invention. The WTRU 200 media access control-e architecture 200 includes a schedule grant processing unit 210, a remaining transmit power calculation unit 215, and a rate requirement processing unit 220.

排程許可處理單元210可從至少一無線鏈路組(RLS)接收至少一排程許可及驅動目前排程許可。排程許可可為從具有主要及次要識別符之服務強化專用頻道胞元被接收之絕對許可225(也就是強化專用頻道無線網路 暫時識別符(E-RNTI)係被用來決定絕對許可是主要亦或次要)，從服務強化專用頻道無線鏈路組被接收之相對許可230或從非服務強化專用頻道無線鏈路被接收之相對許可235。排程許可處理單元210可輸出標示強化傳輸格式組合選擇所使用之排程功率量及用於排程資料媒體存取控制-d流之多工功能之信號240。The schedule license processing unit 210 can receive at least one schedule license from at least one wireless link group (RLS) and drive the current schedule license. Scheduling licenses can be an absolute license for receiving enhanced channel cells from services with primary and secondary identifiers 225 (ie, enhanced dedicated channel wireless networks) The Temporary Identifier (E-RNTI) is used to determine whether the absolute license is primary or secondary, and is received from the service-enhanced dedicated channel radio link group relative license 230 or from the non-service enhanced dedicated channel radio link. Relative license 235. The schedule permission processing unit 210 may output a signal 240 indicating the amount of scheduled power used in the enhanced transport format combination selection and the multiplex function for scheduling the data medium access control-d stream.

排程功率量可被識別為對專用實體控制頻道功率之比率。例如，若專用實體控制頻道功率為P，則排程功率量對專用實體控制頻道功率具有2之比率。排程功率量係為2P。可替代是，排程功率量可被識別為針對排程資料被用來防止傳輸格式組合選擇及多工功能留意專用實體控制頻道功率測量之最大傳輸功率。若專用實體控制頻道功率必須被傳播至媒體存取控制內之不同實體，則因為其快速改變而具有處理支出。再者，將時點同步化係很複雜。因此，因為其他排程相關功能需要目前專用實體控制頻道功率知識，所以僅有留意到專用實體控制頻道功率之媒體存取控制-e中之一實體較佳。The amount of scheduled power can be identified as the ratio of the channel power to the dedicated entity. For example, if the dedicated entity controls the channel power to be P, the scheduled power amount has a ratio of 2 to the dedicated entity control channel power. The scheduled power is 2P. Alternatively, the scheduled power amount can be identified as being used to schedule the data to prevent the transmission format combination selection and multiplex function from paying attention to the maximum transmission power of the dedicated entity control channel power measurement. If the dedicated entity control channel power must be propagated to different entities within the media access control, there is processing overhead due to its rapid change. Furthermore, synchronizing time points is complicated. Therefore, since other scheduling related functions require current dedicated entities to control channel power knowledge, it is preferable to only one of the media access control-e that is aware of the dedicated entity controlling channel power.

當媒體存取控制-e實體105引動媒體存取控制-e功能時，排程許可處理單元210可決定目前服務許可。實體層可提供從AGCH被接收之絕對許可225，標示許可是以主要亦或次要強化專用頻道無線網路暫時識別符被接收。實體層亦提供從各無線鏈路組被接收之相對許可230，235，標示無線鏈路組是服務強化專用頻道無線鏈路組亦或非服務強化專用頻道無線鏈路。絕對許可 225係被發送為對目前上鏈專用實體控制頻道功率之比率信號。被以主要強化專用頻道無線網路暫時識別符接收之絕對許可225永遠重設目前服務許可。若先前被次要強化專用頻道無線網路暫時識別符或許可設定係被設定為零，則被以次要強化專用頻道無線網路暫時識別符接收之絕對許可僅使目前服務許可有效。When the media access control-e entity 105 motivates the media access control-e function, the schedule permission processing unit 210 can determine the current service license. The physical layer may provide an absolute grant 225 that is received from the AGCH, the signing permission being received by the primary or secondary enhanced private channel wireless network temporary identifier. The physical layer also provides a relative grant 230, 235 that is received from each radio link group, indicating that the radio link group is a service enhanced dedicated channel radio link group or a non-service enhanced dedicated channel radio link. Absolute permission The 225 is transmitted as a ratio signal to the current uplink dedicated entity controlling the channel power. The current license is permanently reset by the absolute license 225 received by the primary enhanced dedicated channel wireless network temporary identifier. If the secondary enhanced private channel wireless network temporary identifier or permission setting is previously set to zero, then the absolute permission received by the secondary enhanced private channel wireless network temporary identifier only validates the current service license.

來自非服務強化專用頻道無線鏈路之相對許可230係以步升或步降來調整服務許可。非服務強化專用頻道無線鏈路組之相對許可僅可一步降低服務許可。當來自非服務強化專用頻道無線鏈路組之相對許可向下被接收時，磁滯期間係於其他相對許可向下被忽略期間被啟動。The relative license 230 from the non-service enhanced dedicated channel wireless link adjusts the service license in steps or steps. The relative license of the non-service enhanced dedicated channel radio link group can only reduce the service license in one step. When the relative grant from the non-service enhanced dedicated channel radio link group is received downward, the hysteresis period is initiated while other relative grants are being ignored.

剩餘傳輸功率計算單元215可接收標示實體層所估測之目前專用實體控制頻道功率之信號245，標示媒體存取控制-d所選擇之專用頻道傳輸格式組合或實體層所估測之專用實體資料頻道功率之信號250，可標示來自實體層之高速專用實體控制頻道主動之信號255及標示來自無線資源控制器(RRC)所配置之下層管理實體(LLME)之最大允許功率(具有功率容限)之信號260。若高速專用實體控制頻道為主動，其功率(及來自其他頻道之功率)必須從最大功率被擷取來決定剩餘功率。以信號245，250，255及260為基礎，剩餘傳輸功率計算單元215可輸出標示依據以下方程式(1)被計算之剩餘傳輸功率(Premain )之信號265：P remain =P allowed -P DPDCH -P DPCCH -P HS-DPCCH -P E-DPCCH -Margin； 方程式(1)其中PDPCCH ，PDPDCH ，PHS-DPCCH 及PE-DPCCH 係分別表示專用實體控制頻道，專用實體資料頻道，高速專用實體控制頻道及強化上鏈專用實體控制頻道之功率要求。速率要求處理單元220可監控速率要求之觸發事件，且於觸發事件發生時觸發排程資訊速率要求。速率要求處理單元220可提供可觸發速率要求之邏輯及可建構包含速率要求位元之速率要求訊息270之邏輯。The remaining transmission power calculation unit 215 can receive a signal 245 indicating the current dedicated entity control channel power estimated by the physical layer, indicating the dedicated channel transmission format combination selected by the media access control-d or the dedicated entity data estimated by the physical layer. The channel power signal 250 may indicate a high speed dedicated entity control channel active signal 255 from the physical layer and indicate the maximum allowed power (with power margin) from a Layer Management Entity (LLME) configured by the Radio Resource Controller (RRC). Signal 260. If the high-speed dedicated entity control channel is active, its power (and power from other channels) must be drawn from the maximum power to determine the remaining power. Based on the signals 245, 250, 255 and 260, the remaining transmission power calculation unit 215 can output a signal 265 indicating the remaining transmission power (P remain ) calculated according to the following equation (1): P remain = P allowed - P DPDCH - P DPCCH - P HS-DPCCH - P E-DPCCH -Margin; Equation (1) where P DPCCH , P DPDCH , P HS-DPCCH and P E-DPCCH are respectively dedicated entity control channels, dedicated entity data channels, high speed dedicated The entity controls the channel and strengthens the power requirements of the uplink dedicated entity control channel. The rate requirement processing unit 220 can monitor the triggering event of the rate requirement and trigger the scheduling information rate request when the triggering event occurs. The rate requirement processing unit 220 can provide logic that can trigger rate requirements and logic that can construct a rate requirement message 270 that includes rate requirement bits.

當被映射至強化專用頻道之邏輯頻道上之新資料於無目前排程許可時被接收時，速率要求可被觸發，較高優先性而最後被報導之新資料係被接收於被映射至強化專用頻道之邏輯頻道上，當無目前排程許可且速率要求被更新及定期產生時(其係藉由無線資源控制器配置)，且當服務無線鏈路組確認(ACK)不因先前被傳輸速率要求而被接收時，係產生被更新速率要求。When new data on the logical channel mapped to the enhanced dedicated channel is received without the current scheduling permission, the rate requirement can be triggered, and the higher priority and the last reported new data is received and mapped to the enhanced On the logical channel of the dedicated channel, when there is no current scheduling permission and the rate requirement is updated and periodically generated (which is configured by the radio resource controller), and when the serving radio link group acknowledgement (ACK) is not transmitted previously When the rate request is received, an updated rate requirement is generated.

速率要求係包含所有排程媒體存取控制-d流之總緩衝佔用，任何媒體存取控制-d流之最高優先性資料緩衝佔用，及強化專用頻道傳輸可用之功率餘域空間。The rate requirement includes the total buffer occupancy of all scheduled media access control-d streams, the highest priority data buffer occupancy of any media access control-d stream, and enhanced power headroom available for dedicated channel transmission.

參考第3圖，媒體存取控制-e排程處理300係被解釋如下。針對強化專用頻道傳輸時間區段係被監控，且其決定排程資訊速率要求觸發是否發生及/或是否具有許可之強化專用頻道資料(步驟302)。若無速率要求觸發發生或無強化專用頻道資料，則該處理等待直到下一傳 輸時間區段。若步驟302處之決定為肯定，則進一步決定是否具有可用混合自動重複要求處理(步驟304)。強化傳輸格式組合選擇及強化專用頻道資料傳輸之前，係需混合自動重複要求處理可用性。若無可用混合自動重複要求處理，則處理300等待直到下一傳輸時間區段。若混合自動重複要求處理被決定於步驟304處可用，則目前排程許可及剩餘傳輸功率計算係分別被要求來自排程許可處理單元210及剩餘傳輸功率計算單元215(步驟306)。步驟308中，媒體存取控制-e控制功能係引動排程及強化傳輸格式組合選擇功能以產生媒體存取控制-e協定資料單元。步驟310中，媒體存取控制-e協定資料單元接著以唯一功率偏移及再傳輸最大數被轉送至可用混合自動重複要求處理。Referring to Fig. 3, the media access control-e scheduling process 300 is explained as follows. The enhanced dedicated channel transmission time zone is monitored and it determines whether the scheduled information rate request triggers the occurrence and/or whether there is a licensed enhanced dedicated channel profile (step 302). If there is no rate request triggering or no enhanced dedicated channel data, the process waits until the next pass Time zone. If the decision at step 302 is affirmative, then it is further determined whether there is available hybrid automatic repeat request processing (step 304). Before the enhanced transport format combination selection and enhanced dedicated channel data transmission, it is necessary to mix the automatic repeat request processing availability. If no hybrid automatic repeat request processing is available, then process 300 waits until the next transmission time segment. If the hybrid automatic repeat request processing is determined to be available at step 304, the current schedule grant and remaining transmit power calculations are respectively requested from the schedule grant processing unit 210 and the remaining transmit power calculation unit 215 (step 306). In step 308, the media access control-e control function cites the schedule and enhances the transport format combination selection function to generate a media access control-e protocol data unit. In step 310, the media access control-e-protocol data unit is then forwarded to the available hybrid automatic repeat request processing with the unique power offset and retransmission maximum number.

滿足媒體存取控制-e協定資料單元成形時點要求之單獨實施例中，加速該成形處理之可能媒體存取控制-e協定資料單元之使先計算係被運用。當媒體存取控制-e實體被要求以剩餘功率預算做強化專用頻道傳輸時，該成形處理係搜尋事先成形媒體存取控制-e協定資料單元表(亦即其成形媒體存取控制-e協定資料單元標頭及適當資料區塊協定資料單元)，提供現成資訊至混合自動重複要求/實體層。視時點要求而定具有若干執行該事先處理之方法。In a separate embodiment that satisfies the media access control-e-protocol data unit forming point requirements, the prior computing system that accelerates the possible media access control-e protocol data unit of the forming process is utilized. When the media access control-e entity is required to perform enhanced dedicated channel transmission with the remaining power budget, the forming process searches for a pre-formed media access control-e-protocol data unit table (ie, its formed media access control-e protocol) The data unit header and the appropriate data block agreement data unit) provide ready-made information to the hybrid automatic repeat request/physical layer. There are several methods of performing this prior processing depending on the time point requirements.

第4圖顯示依據本發明被配置之事先處理媒體存取控制-e協定資料單元格式例。被事先處理媒體存取控制 -e協定資料單元格式係包含強化專用頻道或同等物之功率預算，最佳配適該預算或同等物之完全格式化媒體存取控制-e協定資料單元標頭，傳輸序號(TSNs)及資料區塊指標表列，排程資訊及填補位元。Figure 4 shows an example of a pre-processed Media Access Control-e protocol data unit format configured in accordance with the present invention.
