在本發明的具體實施例中,當該指示域同時指示該下行控制通道所對應的傳輸的時域資源以及該下行控制通道所對應的傳輸所在的時間單元的上下行資源劃分時,僅根據其中一種指示內容確定時域資源,或者同時參考兩種指示內容確定時域資源。 In a specific embodiment of the present invention, when the indication field indicates both the time domain resource of the transmission corresponding to the downlink control channel and the uplink and downlink resource division of the time unit where the transmission corresponding to the downlink control channel is located, only according to the One kind of indication content determines the time domain resource, or two kinds of indication content simultaneously determine the time domain resource.
例如:確定該下行控制通道所對應的傳輸的時域資源為該指示域所指示的時域資源,具體同上。 For example, it is determined that the time domain resource of the transmission corresponding to the downlink control channel is the time domain resource indicated by the indication domain, and the details are the same as above.
或者,確定該下行控制通道所對應的傳輸的時域資源為該指示域所指示的上下行資源劃分中的對應資源區域中的全部或者部分資源,具體同上。 Alternatively, it is determined that the time domain resource corresponding to the downlink control channel is all or part of the resources in the corresponding resource area in the uplink and downlink resource division indicated by the indication domain, and the details are the same as above.
或者,確定該下行控制通道所對應的傳輸的時域資源為該指示域所指示的時域資源和該指示域所指示的上下行資源劃分中的對應資源區域中的時域資源中的最大或最小值。 Alternatively, it is determined that the time domain resource corresponding to the downlink control channel is the largest one of the time domain resources indicated by the indication domain and the time domain resources in the corresponding resource region in the uplink and downlink resource division indicated by the indication domain. The minimum value.
即,當該下行控制通道用於調度上行共用通道傳輸時,該上行共用通道在其傳輸的時間單元(可能包含多個時間單元)中按照該指示 域所指示的具體時域資源與該指示域所指示的上下行資源劃所確定的上行區域的時域資源中的最大或最小值或並集或交集進行傳輸;當該下行控制通道用於調度下行共用通道傳輸時,該下行共用通道在傳輸的時間單元(可能包含多個時間單元)中按照該指示域所指示的具體時域資源與該指示域所指示的上下行資源劃分所確定的下行區域中用於傳輸資料的時域資源中的最大或最小值或並集或交集進行傳輸;當該下行控制通道所調度的下行共用通道或該下行控制通道本身需要傳輸ACK/NACK回饋訊息時,該ACK/NACK回饋訊息在其傳輸的時間單元(可能包含多個時間單元)中按照該指示域所指示的具體時域資源與該指示域所指示的上下行資源劃分所確定的上行區域的全部時域資源或預先約定的部分時域資源中的最大或最小值或並集或交集進行傳輸。 That is, when the downlink control channel is used to schedule an uplink shared channel transmission, the uplink shared channel follows the instruction in the time unit (which may include multiple time units) of its transmission. The maximum or minimum or union or intersection of the time domain resources indicated by the specific time domain resources indicated by the domain and the uplink region determined by the uplink and downlink resource planning indicated by the indication domain; when the downlink control channel is used for scheduling When the downlink shared channel is transmitted, the downlink shared channel determines the downlink in the transmission time unit (which may include multiple time units) according to the specific time domain resources indicated by the indication domain and the uplink and downlink resource division indicated by the indication domain. The maximum or minimum or union or intersection of the time domain resources used to transmit data in the area is transmitted; when the downlink shared channel scheduled by the downlink control channel or the downlink control channel itself needs to transmit ACK / NACK feedback messages, The ACK / NACK feedback message in the time unit (which may include multiple time units) is transmitted in accordance with the specific time domain resources indicated by the indication field and the uplink and downlink resources indicated by the indication field. The time domain resource or the pre-agreed part of the time domain resource is transmitted to the maximum or minimum value or union or intersection.
步驟103:在該時域資源上傳輸資料。 Step 103: transmitting data on the time domain resource.
具體的,當該下行控制通道為使用上行DCI格式的下行控制通道時,該終端在該時域資源上傳輸該下行控制通道所調度的上行共用通道;當該下行控制通道為使用下行DCI格式的下行控制通道時,該終端在該時域資源上傳輸該下行控制通道所調度的下行共用通道;或者,當該下行控制通道為使用下行DCI格式的下行控制通道時,該終端在該時域資源上傳輸該下行控制通道所調度的下行共用通道所對應的ACK/NACK回饋訊息或該下行控制通道所對應的ACK/NACK回饋訊息。 Specifically, when the downlink control channel is a downlink control channel using an uplink DCI format, the terminal transmits an uplink shared channel scheduled by the downlink control channel on the time domain resource; when the downlink control channel is a downlink DCI format When the downlink control channel is used, the terminal transmits the downlink shared channel scheduled by the downlink control channel on the time domain resource; or when the downlink control channel is a downlink control channel using the downlink DCI format, the terminal uses the time domain resource. The ACK / NACK feedback message corresponding to the downlink shared channel scheduled by the downlink control channel or the ACK / NACK feedback message corresponding to the downlink control channel is transmitted upward.
另外,在上述過程中,終端還可以在每個或特定(例如預先配置或約定的發送指示訊息的時間單元中)的時間單元中檢測指示訊息, 該指示訊息用於指示一個或多個時間單元中的上下行資源劃分。 In addition, in the above process, the terminal may also detect the instruction message in each or a specific time unit (for example, in a pre-configured or agreed time unit for sending the instruction message), The indication message is used to indicate uplink and downlink resource allocation in one or more time units.
如果終端檢測的指示訊息所指示的上下行資源劃分與該下行控制通道中的指示域的指示內容不一致,則以該下行控制通道中的指示域的指示內容為準。 If the uplink and downlink resource division indicated by the indication message detected by the terminal is not consistent with the indication content of the indication field in the downlink control channel, the indication content of the indication field in the downlink control channel shall prevail.
當該下行控制通道中的指示域指示時域資源時,該時域資源開始於一個時間單元的第一個符號時,確定該時間單元為全上行,或該時域資源跨越兩個時間單元時,確定第二個時間單元為全上行。 When the indication domain in the downlink control channel indicates a time domain resource, when the time domain resource starts at the first symbol of a time unit, it is determined that the time unit is full uplink, or when the time domain resource spans two time units To determine that the second time unit is full uplink.
當終端根據該指示域確定該目標時間單元為全上行時(例如時域資源占滿一個時間單元,或根據上下行資源劃分確定為全上行),在該目標時間單元中終端可以不檢測用於指示時間單元中上下行資源劃分的指示訊息,從而達到節電的目的。 When the terminal determines that the target time unit is full uplink according to the indication field (for example, the time domain resource occupies a time unit or is determined to be full uplink according to the uplink and downlink resource division), the terminal may not detect the target time unit for An instruction message indicating the uplink and downlink resource division in the time unit, thereby achieving the purpose of power saving.
需要說明的是,如果該下行控制通道中存在指示域可以指示該上行共用通道的時域資源,則該下行控制通道中的指示域所指示的時域資源可以小於、等於、或者大於根據該指示訊息確定該上行區域的大小;當大於該根據該指示訊息確定該上行區域的大小時,可以總是按照該上行區域的大小傳輸,或者總是按照該下行控制通道中的指示域所指示的時域資源傳輸,或者取該上行區域的大小和該下行控制通道中的指示域所指示的時域資源的最大值或最小值。 It should be noted that if there is an indication domain in the downlink control channel that can indicate the time domain resource of the uplink shared channel, the time domain resource indicated by the indication domain in the downlink control channel can be less than, equal to, or greater than that according to the instruction. The message determines the size of the uplink area; when it is larger than the size of the uplink area determined according to the instruction message, it can always be transmitted according to the size of the uplink area, or always as indicated by the indication field in the downlink control channel. Domain resource transmission, or take the size of the uplink area and the maximum or minimum value of the time domain resource indicated by the indication domain in the downlink control channel.

第三實施例Third embodiment
該實施例為本發明資料傳輸方法的一具體應用實例。 This embodiment is a specific application example of the data transmission method of the present invention.
本發明實施例以一個slot為一個時間單元為例,假設一個slot包含7個符號(正交頻分複用OFDM或單載波頻分多址SC-FDMA符號);當然不排除其他長度的時間單元定義方式。 The embodiment of the present invention uses a slot as a time unit as an example. Assume that a slot contains 7 symbols (orthogonal frequency division multiplexed OFDM or single-carrier frequency division multiple access SC-FDMA symbols); of course, other time units are not excluded. Definition.
本發明實施例的資料傳輸方法的具體實現過程如下。 The specific implementation process of the data transmission method in the embodiment of the present invention is as follows.
假設當前時間單元中的下行區域中發送的UL grant可以調度當前時間單元的上行區域中進行PUSCH傳輸(即終端的上行處理時延足夠,當然這個調度關係也可以不是預先約定的,可以是UL grant中通知的,例如直接通知PUSCH在當前或後一個或後面的幾個時間單元中傳輸),UL grant中包含指示域,用於指示被調度的PUSCH的時域資源。 It is assumed that the UL grant sent in the downlink area of the current time unit can schedule PUSCH transmission in the uplink area of the current time unit (that is, the uplink processing delay of the terminal is sufficient, of course, this scheduling relationship may not be predetermined, and it may be a UL grant). (For example, the PUSCH is directly notified to be transmitted in the current or later or later time units), and the UL grant includes an indication domain for indicating the time domain resources of the scheduled PUSCH.
基地台側: Base station side:
如圖3所示,基地台在一個時間單元中發送UL grant,用於調度相應的終端在該時間單元中的UL grant的指示域所指示的時域資源上傳輸PUSCH;例如在時間單元i中發送UL grant1,其中的指示域指示在第6和7個符號上傳輸PUSCH1(即既通知符號位置又通知符號長度),或指示在2個符號上傳輸PUSCH1(此時可以預設為是時間單元的結束位置向前的兩個符號,即時間單元中的最後2個符號,從而可以不用通知符號位置,僅通知符號長 度),當然還可以有其他指示方式,例如包含時隙編號/個數、min-slot編號/個數等,還可以指示是否跨越相鄰的時隙傳輸等;當然,UL grant指示的時域資源大小還可以小於預先配置或定義的該時間單元中的上行區域的大小,例如時間單元i+1中UL grant2所調度的PUSCH2所示。 As shown in FIG. 3, the base station sends a UL grant in a time unit for scheduling a corresponding terminal to transmit a PUSCH on the time domain resource indicated by the indication field of the UL grant in the time unit; for example, in time unit i Send UL grant1, where the indication field indicates that PUSCH1 is transmitted on the 6th and 7th symbols (that is, both the position of the symbol and the length of the symbol are notified), or that PUSCH1 is transmitted on 2 symbols (at this time, it can be preset to be a time unit The end position of the two symbols forward, that is, the last 2 symbols in the time unit, so that the position of the symbol can be notified without the notification of the length of the symbol. Degrees), of course, there can be other indication methods, such as including slot number / number, min-slot number / number, etc., and can also indicate whether to transmit across adjacent time slots; of course, the time domain indicated by UL grant The resource size may also be smaller than the size of the uplink area configured or defined in the time unit in advance, for example, as shown in PUSCH2 scheduled by UL grant2 in time unit i + 1.
需要說明的是,基地台可以根據調度需求等先驗訊息預先劃分一個時間單元的下行區域和上行區域,基地台發送UL grant中的指示域所指示的PUSCH時域資源需要包含在該上行區域中;當然基地台也可以不預先劃分,而根據實際的調度需求在UL grant中靈活指示PUSCH在哪個時域位置傳輸,從而靈活調整上行區域大小。 It should be noted that the base station may pre-divide the downlink region and the uplink region of a time unit according to a priori information such as scheduling requirements, and the PUSCH time domain resources indicated by the base station sending the UL domain in the UL grant need to be included in the uplink region. ; Of course, the base station may not be divided in advance, but according to the actual scheduling needs, the UL grant can flexibly indicate in which time domain position the PUSCH is transmitted, thereby flexibly adjusting the size of the uplink area.
在上述UL grant中的指示域所指示的時域資源上,根據UL grant中的調度訊息(如頻域資源、MCS等)上接收終端發送的PUSCH。 The PUSCH sent by the terminal is received on the time domain resources indicated by the indication field in the UL grant according to the scheduling information (such as frequency domain resources, MCS, etc.) in the UL grant.
終端側: Terminal side:
終端在每個時間單元中檢測UL grant,當接收到UL grant時,根據UL grant中的指示域確定被調度的PUSCH的時域資源(具體方式同上),然後根據UL grant中的調度訊息(如頻域資源,MCS等級等),在該時間單元中的相應的時域資源上傳輸PUSCH。 The terminal detects the UL grant in each time unit. When receiving the UL grant, the terminal determines the time domain resources of the scheduled PUSCH according to the indication field in the UL grant (the specific method is the same as above), and then according to the scheduling information in the UL grant (such as Frequency domain resources, MCS level, etc.), and the PUSCH is transmitted on corresponding time domain resources in the time unit.

Assume that a slot contains 7 symbols (orthogonal frequency division multiplexed OFDM or single-carrier frequency division multiple access SC-FDMA symbols); of course, other time units are not excluded. Definition.
本發明實施例的資料傳輸方法的具體實現過程如下。 The specific implementation process of the data transmission method in the embodiment of the present invention is as follows.
假設當前時間單元中的下行區域中發送的UL grant可以調度後一個時間單元的上行區域中進行PUSCH傳輸(當然這個調度關係也可以不是預先約定的,可以是UL grant中通知的,例如直接通知PUSCH在當前或後一個或後面的幾個時間單元中傳輸),UL grant中包含指示域,用於指示被調度的PUSCH的時域資源。 It is assumed that the UL grant sent in the downlink area in the current time unit can be scheduled for PUSCH transmission in the uplink area of the subsequent time unit (of course, this scheduling relationship may not be pre-agreed, and it may be notified in the UL grant, for example, the PUSCH is notified directly It is transmitted in the current time or the next time unit or later), the UL grant includes an indication domain, which is used to indicate the time domain resources of the scheduled PUSCH.

如圖4所示,基地台在一個時間單元中發送UL grant,用於調度相應的終端在下一個時間單元或下一個時間單元開始的多個時間單元的UL grant中的指示域指示的時域資源上傳輸PUSCH;例如在時間單元i中發送UL grant1,其中的指示域指示在下一個時間單元中的第6和7個符號上傳輸PUSCH1(即既通知符號位置又通知符號長度),或指示在2個符號上傳輸PUSCH1(此時可以預設為是時間單元的結束位置向前的兩個符號,即時間單元中的最後2個符號,從而可以不用通知符號位置,僅通知符號長度),當然還可以有其他指示方式,例如包含時隙編號/個數、min-slot編號/個數等,還可以指示是否跨越相鄰的時隙傳輸等;基地台還可以在時間單元i中發送UL grant2,調度PUSCH2在時間單元i+1中的第6個符號開始、連續9個符號傳輸,此時終端可以直接判斷時間單元i+2為全上行,其中,UL grant2中的指示域可以直接指示PUSCH2從時間單元i+1中的第6個符號開始、長度為9個符號,則PUSCH2跨越時間單元i+1和i+2傳輸,UL grant2中的指示域也可以僅通知PUSCH2跨越兩個時間單元傳輸,則預設PUSCH2佔用時間單元i+1和時間單元i+2中的全部上行符號傳輸;基地台還可以在時間單元i+1中發送UL grant3,調度在時間單元i+2中從第一個符號開始傳 輸PUSCH3,此時終端可以直接判斷時間單元i+2為全上行,UL grant3中的指示域可以直接通知PUSCH3從時間單元i+2中的第一個符號開始,則預設佔用一個時間單元傳輸,UL grant3中的指示域也可以通知PUSCH3佔用7個符號傳輸,則預設需要佔用一個時間單元,即從第一個符號開始傳輸到最後一個符號結束。當然,PUSCH1也可以被調度佔用時間單元i+1中的上行區域中的部分符號(例如僅佔用最後一個符號)傳輸,PUSCH2也可以被調度佔用時間單元i+1中的上行區域中的部分符號(例如從時間單元中的最後一個符號開始)和/或佔用時間單元i+2中的部分符號傳輸,PUSCH3也可以被調度僅佔用時間單元i+2中的部分符號傳輸。 As shown in FIG. 4, the base station sends a UL grant in one time unit, which is used to schedule the time domain resources indicated by the indication domain in the UL grant of the corresponding terminal in the next time unit or multiple time units starting from the next time unit. PUSCH is transmitted; for example, UL grant1 is sent in time unit i, where the indication field indicates that PUSCH1 is transmitted on the 6th and 7th symbols in the next time unit (that is, both the position of the symbol and the length of the symbol), or 2 PUSCH1 is transmitted on each symbol (at this time, it can be preset to be the two symbols forward from the end position of the time unit, that is, the last 2 symbols in the time unit, so that only the symbol length can be notified without the position of the symbol), of course There may be other indication methods, such as including slot number / number, min-slot number / number, etc., and it may also indicate whether to transmit across adjacent time slots, etc .; the base station may also send UL grant2 in time unit i, Schedule PUSCH2 to start at the sixth symbol in time unit i + 1 and transmit 9 consecutive symbols. At this time, the terminal can directly determine that time unit i + 2 is full uplink. Among them, UL grant2 The indication field of PUSCH2 can directly instruct PUSCH2 to start from the sixth symbol in time unit i + 1 and has a length of 9 symbols. Then, PUSCH2 is transmitted across time units i + 1 and i + 2, and the indication field in UL grant2 can only be Inform PUSCH2 to transmit across two time units, then it is preset that PUSCH2 occupies all uplink symbol transmissions in time unit i + 1 and time unit i + 2; the base station can also send UL grant3 in time unit i + 1 and schedule in time Unit i + 2 starts with the first symbol Input PUSCH3, at this time, the terminal can directly judge time unit i + 2 as full uplink, and the indication field in UL grant3 can directly notify PUSCH3 to start with the first symbol in time unit i + 2, and it will preset to occupy one time unit for transmission The indication field in UL grant3 can also inform PUSCH3 to occupy 7 symbol transmissions, and it is preset to occupy a time unit, that is, the transmission starts from the first symbol and ends at the end of the last symbol. Of course, PUSCH1 can also be scheduled to occupy some symbols in the uplink area in time unit i + 1 (for example, only the last symbol is occupied), and PUSCH2 can also be scheduled to occupy some symbols in the uplink area in time unit i + 1. (For example, starting from the last symbol in the time unit) and / or occupying part of the symbol transmission in time unit i + 2, PUSCH3 may also be scheduled to occupy only part of the symbol transmission in time unit i + 2.
需要說明的是,基地台可以根據調度需求等先驗訊息預先劃分一個時間單元的下行區域和上行區域,基地台發送UL grant中的指示域所指示的PUSCH時域資源需要包含在該上行區域中;當然基地台也可以不預先劃分,而根據實際的調度需求在UL grant中靈活指示PUSCH在哪個時域位置傳輸,從而靈活調整上行區域大小。 It should be noted that the base station may pre-divide the downlink region and the uplink region of a time unit according to a priori information such as scheduling requirements, and the PUSCH time domain resources indicated by the base station sending the UL domain in the UL grant need to be included in the uplink region. ; Of course, the base station may not be divided in advance, but according to the actual scheduling needs, the UL grant can flexibly indicate in which time domain position the PUSCH is transmitted, thereby flexibly adjusting the size of the uplink area.
在上述UL grant中的指示域所指示的時域資源上,根據UL grant中的調度訊息(如頻域資源、MCS等)上接收終端發送的PUSCH。 The PUSCH sent by the terminal is received on the time domain resources indicated by the indication field in the UL grant according to the scheduling information (such as frequency domain resources, MCS, etc.) in the UL grant.
終端側: Terminal side:
如圖4所示,在每個時間單元中檢測UL grant,當接收到UL grant時,根據UL grant中的指示域確定被調度的PUSCH的時域資源(具體方式同上),然後根據UL grant中的調度訊息(如頻域資源,MCS等級等),在該時間單元中的相應的時域資源上傳輸PUSCH。 As shown in FIG. 4, the UL grant is detected in each time unit. When a UL grant is received, the time domain resource of the scheduled PUSCH is determined according to the indication field in the UL grant (the specific method is the same as above), and then according to the UL grant, Scheduling information (such as frequency domain resources, MCS level, etc.), and PUSCH is transmitted on corresponding time domain resources in the time unit.
第五實施例Fifth Embodiment
該實施例為本發明資料傳輸方法的再一具體應用實例。 This embodiment is another specific application example of the data transmission method of the present invention.
本發明實施例以一個slot為一個時間單元為例,假設一個slot包含7個符號(正交頻分複用OFDM或單載波頻分多址SC-FDMA符號);當然不排除其他長度的時間單元定義方式。 The embodiment of the present invention uses a slot as a time unit as an example. Assume that a slot contains 7 symbols (orthogonal frequency division multiplexed OFDM or single-carrier frequency division multiple access SC-FDMA symbols); of course, other time units are not excluded. Definition.
本發明實施例的資料傳輸方法的具體實現過程如下。 The specific implementation process of the data transmission method in the embodiment of the present invention is as follows.
假設當前時間單元中的下行區域中發送的UL grant可以調度當前或後一個時間單元的上行區域中進行PUSCH傳輸(可以是不同終端維護不同的調度關係,當然這個調度關係也可以不是預先約定的,可以是UL grant中通知的,例如直接通知PUSCH在當前或後一個或後面的幾個時間單元中傳輸),UL grant中包含指示域,用於指示被調度的PUSCH傳輸所在的時間單元的上下行資源劃分。 It is assumed that the UL grant sent in the downlink area in the current time unit can schedule PUSCH transmission in the uplink area of the current or later time unit (it may be that different terminals maintain different scheduling relationships, of course, this scheduling relationship may not be pre-agreed, It can be notified in the UL grant, for example, the PUSCH is directly notified to be transmitted in the current or the next or later time units. The UL grant contains an indication field to indicate the uplink and downlink of the time unit where the scheduled PUSCH transmission is located. Division of resources.
基地台側: Base station side:
如圖5所示,基地台在一個時間單元中發送UL grant,用於調度相應的終端在下一個時間單元或下一個時間單元開始的多個時間單元中傳輸PUSCH,PUSCH的傳輸時域資源則根據該UL grant中的指示域所指示的該時間單元的上下行資源劃分來確定;例如在時間單元i中發送UL grant1,用於調度終端在時間單元i+1中傳輸PUSCH1,其中的指示域指示下一個時間單元i+1的上下行資源劃分,可以直接指示下行區域的符號數、上行區域的符號數、GP符號數中的至少2個訊息,也可以指示預定的時間單元的結構類型,例如預定全上行結構、下行4符號+上行2符號結構(1符號GP)、下行2符號+上行4符號結構(1符號GP)等,則根據指示域的指示訊息,確定時間單元i+1中上下行劃分為下行6符號+上行2符號,則預設該UL grant1調度的PUSCH1在時間單元i+1中的上行區域佔用所有符號傳輸,即佔用時間單元i+1中的第6、7個符號(即最後2個符號)傳輸;基地台可以在時間單元i+1中發送UL grant2,用於調度終端在時間單元i+2中傳輸PUSCH2,其中的指示域指示下一個時間單元i+2的上下行資源劃分,按照類似UL grant1中的指示方式,根據UL grant2中的指示域確定時間單元i+2為全上行,則默認該UL grant2調度的PUSCH2在時間單元i+2中的全部符號上傳輸。 As shown in Figure 5, the base station sends a UL grant in one time unit, which is used to schedule the corresponding terminal to transmit PUSCH in the next time unit or multiple time units starting from the next time unit, and the PUSCH transmission time domain resources are based on Determine the uplink and downlink resource division of the time unit indicated by the indication field in the UL grant; for example, send UL grant1 in time unit i to schedule the terminal to transmit PUSCH1 in time unit i + 1, where the indication field indicates The uplink and downlink resource division of the next time unit i + 1 can directly indicate at least 2 messages in the number of symbols in the downlink area, the number of symbols in the uplink area, and the number of GP symbols, and it can also indicate the structure type of the predetermined time unit, such as Predetermined full uplink structure, downlink 4 symbols + uplink 2 symbols structure (1 symbol GP), downlink 2 symbols + uplink 4 symbols structure (1 symbol GP), etc., according to the indication information of the indication field, the upper and lower positions of the time unit i + 1 are determined The line is divided into 6 symbols in the downlink + 2 symbols in the uplink, then the UL is preset The PUSCH1 scheduled by grant1 occupies all symbol transmissions in the uplink area in time unit i + 1, that is, the 6th and 7th symbols (that is, the last 2 symbols) in time unit i + 1 are used for transmission; the base station may transmit in time unit i A UL grant2 is sent in +1, which is used to schedule the terminal to transmit PUSCH2 in time unit i + 2, where the indication field indicates the uplink and downlink resource division of the next time unit i + 2, in a similar manner to the indication in UL grant1, according to UL The indication field in grant2 determines that time unit i + 2 is full uplink, and by default, PUSCH2 scheduled by the UL grant2 is transmitted on all symbols in time unit i + 2.
進一步,如果不同的終端可以維護的調度關係不同,例如存在一類終端按照UL grant1和UL grant2的方式進行跨時間單元的調度,還可以存在一類終端可以按照UL grant3的方式進行一個時間單元內的調度,即基地台還可以在時間單元i+1中發送UL grant3,調度在時間單元i+1中的上行區域開始傳輸PUSCH3,按照類似UL grant1中的指示方式,根據UL grant3中的指示域確定時間單元i+2為全上行,則一種實現方式為終端總是認為UL grant3所調度的PUSCH3僅在時間單元i+1中的上行區域傳輸,例如該上行區域為2個符號,則PUSCH3總是在時間單元i+1中的最後2個符號上傳輸。另一種實現方式,由於終端可以根據UL grant3中的指示域確定時間單元i+2為全上行,則可以默認該UL grant3調度的PUSCH3在時間單元i+1和時間單元i+2中的全部符號上傳輸,另一種實現方式,UL grant3中的指示域還可以進一步指示PUSCH3是否跨域不同的時間單元傳輸或指示PUSCH3傳輸的具體符號位置/數量等(類似實施例1/2中的時域資源指示),則終端可以根據該指示訊息確定PUSCH3僅在時間單元i+1中的2個符號上傳輸,還是會跨域時間單元i+1和i+2佔用9個符號傳輸。 Further, if different terminals can maintain different scheduling relationships, for example, there is a type of terminal that performs scheduling across time units according to UL grant1 and UL grant2, and a type of terminal that can perform scheduling within a time unit according to UL grant3 That is, the base station can also send UL grant3 in time unit i + 1, schedule to start transmitting PUSCH3 in the uplink area in time unit i + 1, and determine the time according to the indication field in UL grant3 in a similar manner to that in UL grant1. Unit i + 2 is full uplink. One implementation is that the terminal always considers that PUSCH3 scheduled by UL grant3 is transmitted only in the uplink area in time unit i + 1. For example, if the uplink area is 2 symbols, PUSCH3 is always in The last two symbols in time unit i + 1 are transmitted. In another implementation manner, since the terminal can determine that the time unit i + 2 is full uplink according to the indication field in the UL grant3, all symbols in the time unit i + 1 and the time unit i + 2 of the PUSCH3 scheduled by the UL grant3 can be defaulted. Transmission, another implementation, the indication field in UL grant3 can further indicate whether PUSCH3 is transmitted across different time units in the domain or indicate the specific symbol position / number of PUSCH3 transmissions (similar to the time domain resource in Embodiment 1/2) Indication), the terminal may determine, according to the indication message, that the PUSCH3 is transmitted on only 2 symbols in the time unit i + 1, or whether it will occupy 9 symbols for transmission across the time units i + 1 and i + 2.
當然,如果每個UL grant中的指示域都還進一步包含了指示PUSCH的時域資源的訊息(如實施例1/2中的指示訊息),則PUSCH1、2、3所佔用的符號數可以小於上行區域的符號數,即不占滿一個時間單元中的上行區域包含的所有符號。 Of course, if the indication field in each UL grant further includes information indicating the time domain resources of the PUSCH (such as the indication message in Embodiment 1/2), the number of symbols occupied by PUSCH 1, 2, and 3 may be less than The number of symbols in the uplink area, that is, not all the symbols contained in the uplink area in one time unit.
在上述根據UL grant中的指示域所確定的時域資源上,根據UL grant中的調度訊息(如頻域資源、MCS等)上接收終端發送的PUSCH。 The PUSCH sent by the terminal is received on the time domain resources determined according to the indication field in the UL grant according to the scheduling information (such as frequency domain resources, MCS, etc.) in the UL grant.
終端側: Terminal side:
如圖5所示,在每個時間單元中檢測UL grant,當接收到UL grant時,根據UL grant中的指示域確定被調度的PUSCH的時域資源(具體方式同上),然後根據UL grant中的調度訊息(如頻域資源,MCS等級等),在該時間單元中的相應的時域資源上傳輸PUSCH。 As shown in FIG. 5, the UL grant is detected in each time unit. When a UL grant is received, the time domain resources of the scheduled PUSCH are determined according to the indication field in the UL grant (the specific method is the same as above), and then according to the UL grant, Scheduling information (such as frequency domain resources, MCS level, etc.), and PUSCH is transmitted on corresponding time domain resources in the time unit.

When the UL grant and PUSCH are replaced with DL grant and PDSCH, or when the DL grant and the corresponding ACK / NACK feedback are replaced. The working method is similar and will not be described again.
