Technical field

本发明涉及通信技术领域，尤其涉及一种数据传输方法及装置。The present invention relates to the field of communications technologies, and in particular, to a data transmission method and apparatus.

Background technique

随着移动通信业务需求的发展变化，国际电信联盟等多个组织对未来移动通信系统都定义了更高的用户面延时性能要求。缩短用户时延性能的主要方法之一是降低传输时间间隔(Transmission Time Interval，TTI)长度，即支持短TTI(short TTI，sTTI)传输。短TTI传输一种比较典型的工作方式即在LTE现有机制中定义的子帧结构中包含多个短于1ms的sTTI传输，例如2符号或3符号或4符号或7符号等长度的传输，当然也不排除其他短于1ms的长度的sTTI传输。上行支持sPUSCH和sPUCCH，sPUCCH至少可以用于承载使用sTTI的下行传输的ACK/NACK反馈信息。With the development of mobile communication services, many organizations such as the International Telecommunication Union have defined higher user plane delay performance requirements for future mobile communication systems. One of the main methods for shortening the user delay performance is to reduce the transmission time interval (TTI) length, that is, support short TTI (sTTI) transmission. A typical working mode of short TTI transmission is to include multiple sTTI transmissions shorter than 1 ms in a subframe structure defined in the existing LTE mechanism, for example, a 2-symbol or a 3-symbol or a 4-symbol or 7-symbol transmission. Of course, other sTTI transmissions shorter than 1 ms are not excluded. The uplink supports sPUSCH and sPUCCH, and the sPUCCH can be used to carry at least ACK/NACK feedback information of downlink transmission using sTTI.

支持sTTI传输的终端还可以支持1ms TTI和sTTI之间的动态切换，即终端可能在一个子帧中同时存在使用1ms TTI长度的信道以及使用sTTI的信道，例如在同一个子帧中同时存在物理上行共享信道(Physical Uplink Shared CHannel，PUSCH)和短PUSCH(short PUSCH，sPUSCH)/短物理上行控制信道(short Physical Uplink Control Channel，sPUCCH)，又例如在同一个子帧中同时被调度传输物理下行共享信道(Physical Uplink Shared CHannel，PDSCH)和短PDSCH(short PDSCH，sPDSCH)，又例如在同一个子帧中同时存在PUCCH和sPUSCH/sPUCCH，等等。A terminal that supports sTTI transmission can also support dynamic switching between 1 ms TTI and sTTI. That is, the terminal may have a channel using 1 ms TTI length and a channel using sTTI in one subframe, for example, physical uplink exists in the same subframe. The Physical Uplink Shared CHannel (PUSCH) and the short PUSCH (sPUSCH)/short Physical Uplink Control Channel (sPUCCH) are simultaneously scheduled to transmit the physical downlink shared channel, for example, in the same subframe. (Physical Uplink Shared CHannel, PDSCH) and Short PDSCH (short PDSCH, sPDSCH), for example, PUCCH and sPUSCH/sPUCCH are present in the same subframe, and so on.

上述传输可能在同一个载波上同时存在，此时，对于上行，为了保证单载波特性以实现较低的PAPR/CM，同一个终端不能在同一个载波上同时发送PUSCH和sPUSCH/sPUCCH，或同时发送PUCCH和/sPUSCH/sPUCCH。目前还没有相关方案解决这种碰撞问题以保证单载波特性。The above transmissions may exist on the same carrier at the same time. In this case, for the uplink, in order to ensure the single carrier characteristics to achieve a lower PAPR/CM, the same terminal cannot simultaneously transmit the PUSCH and the sPUSCH/sPUCCH on the same carrier, or simultaneously Transmit PUCCH and /sPUSCH/sPUCCH. There is currently no solution to this collision problem to guarantee single carrier characteristics.

上述传输也可能在终端聚合了多个载波时，在不同的载波上同时存在，此时，所有并行传输的上行信道的发射功率之和不能超过终端允许的最大发射功率限制，否则终端的发射功率受限，目前还没有相关方案解决这种碰撞问题以避免功率受限。The foregoing transmission may also exist on different carriers when the terminal aggregates multiple carriers. At this time, the sum of the transmit powers of all uplink channels transmitted in parallel may not exceed the maximum transmit power limit allowed by the terminal, otherwise the transmit power of the terminal Limited, there is currently no solution to solve this collision problem to avoid power limitation.

因此，如何解决不同TTI长度的上行信道的碰撞问题，以保证单载波特性和避免功率受限还没有相关方案。Therefore, there is no related solution to how to solve the collision problem of the uplink channel with different TTI lengths to ensure single carrier characteristics and avoid power limitation.

All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

本实施例中的数据传输方法主要应用于终端、基站等装置，当然，还可以是其它装置，在此，本申请不作限制。本实施例主要以应用于终端为例进行详细阐述，当应用于基站时，对应终端的发送行为则为基站的接收行为。The data transmission method in this embodiment is mainly applied to a device such as a terminal or a base station, and of course, other devices may be used. Here, the application is not limited. This embodiment is mainly applied to the terminal as an example for detailed description. When applied to a base station, the sending behavior of the corresponding terminal is the receiving behavior of the base station.

本发明实施例中，如图1所示，数据传输过程如下：In the embodiment of the present invention, as shown in FIG. 1, the data transmission process is as follows:

步骤101：确定在时间单元i中存在使用第一传输时间间隔TTI长度传输的第一上行信道以及使用第二传输时间间隔TTI长度传输的第二上行信道，所述第一上行信道与所述第二上行信道在时间上存在重叠；Step 101: Determine that there is a first uplink channel transmitted in the time unit i using the first transmission time interval TTI length and a second uplink channel transmitted in the second transmission time interval TTI length, where the first uplink channel and the first uplink channel The two uplink channels overlap in time;

步骤102：获得确定在所述时间单元i中存在所述第二上行信道的时间节点；和/或获得在所述时间单元i中所述第二上行信道与所述第一上行信道的重叠符号位置；Step 102: Obtain a time node that determines that the second uplink channel exists in the time unit i; and/or obtain an overlapping symbol of the second uplink channel and the first uplink channel in the time unit i position;

步骤103：基于所述时间节点和/或所述重叠符号位置，确定在所述时间单元i中需要传输的上行信道并进行传输；Step 103: Determine, according to the time node and/or the overlapping symbol position, an uplink channel that needs to be transmitted in the time unit i and perform transmission;

所述第一传输时间间隔TTI长度大于所述第二传输时间间隔TTI长度；和/或The first transmission time interval TTI length is greater than the second transmission time interval TTI length; and/or

具体的，在本实施例中，终端确定能支持使用第一传输时间间隔TTI长度传输的上行信道与使用第二传输时间间隔TTI长度传输的上行信道同时传输。所述第一传输时间间隔TTI长度可以为1ms，所述第二传输时间间隔TTI长度可以为不超过1ms的sTTI长度，如2、3、4、7个符号等，或所述第一传输时间间隔TTI长度和所述第二传输时间间隔TTI长度都为不超过1ms的两个不同的sTTI长度。并且，终端还需确定能支持使用第一传输时间间隔TTI长度传输的上行控制信道与使用第二传输时间间隔TTI长度传输的上行共享信道同时传输，和/或能支持使用第一传输时间间隔TTI长度传输的上行共享信道与使用第二传输时间间隔TTI长度传输的上行控制信道同时传输。Specifically, in this embodiment, the terminal determines that the uplink channel that can be transmitted using the first transmission time interval TTI length and the uplink channel that is transmitted using the second transmission time interval TTI length are simultaneously transmitted. The length of the first transmission time interval TTI may be 1 ms, and the length of the second transmission time interval TTI may be an sTTI length of no more than 1 ms, such as 2, 3, 4, 7 symbols, etc., or the first transmission time. Both the interval TTI length and the second transmission time interval TTI length are two different sTTI lengths of no more than 1 ms. Moreover, the terminal further needs to determine that the uplink control channel capable of transmitting using the first transmission time interval TTI length and the uplink shared channel transmitted using the second transmission time interval TTI length are simultaneously transmitted, and/or can support the use of the first transmission time interval TTI The uplink shared channel of the length transmission is simultaneously transmitted with the uplink control channel transmitted using the second transmission time interval TTI length.

进而，在时间单元i中，终端可能同时存在使用第一传输时间间隔TTI长度传输的第一上行信道以及使用第二传输时间间隔TTI长度传输的第二上行信道，第一上行信道和第二上行信道可以在同一个载波上或者在不同的载波上。Further, in the time unit i, the terminal may simultaneously have a first uplink channel transmitted using the first transmission time interval TTI length and a second uplink channel transmitted using the second transmission time interval TTI length, the first uplink channel and the second uplink The channels can be on the same carrier or on different carriers.

对于上行，为了保证单载波特性以实现较低的PAPR/CM，同一个终端不能在同一个载波上同时发送PUSCH和sPUSCH/sPUCCH，或同时发送PUCCH和/sPUSCH/sPUCCH。现有技术中可能的解决方案为可以放弃其中一个或多个信道传输，或者对使用1ms TTI的上行信道在与sTTI重叠部分进行打孔，以避免上述重叠传输。但如果终端在开始发送1ms TTI长度的上行信道(如PUSCH或PUCCH)之前没有足够时间判断在PUSCH或PUCCH所在的子帧中是否存在使用sTTI的上行信道传输时，终端不能及时放弃对使用1ms TTI的上行信道的传输。对于PUCCH format 1/1a/1b/3，在时域上存在正交序列，如果对一个时隙中的部分符号进行打孔，则破坏正交性，导致该终端的被打孔的PUCCH对与该终端在同一个资源块(RB，Resource Block)中复用传输的其他终端产生干扰。对于PUSCH，如果进行MU-MIMO，则如果打孔位置是RS，将导致基站侧无法获取该终端的RS，从而在接收与该终端进行MU-MIMO传输的其他终端的PUSCH时，无法对其他终端的PUSCH进行基于该终端的RS的干扰消除，从而导致该终端的数据对其他MU-MIMO终端的数据的干扰。For uplink, in order to ensure single carrier characteristics to achieve lower PAPR/CM, the same terminal cannot simultaneously transmit PUSCH and sPUSCH/sPUCCH on the same carrier, or simultaneously transmit PUCCH and /sPUSCH/sPUCCH. A possible solution in the prior art is to discard one or more of the channel transmissions, or to punct the overlap with the sTTI for the upstream channel using the 1 ms TTI to avoid the above overlapping transmission. However, if the terminal does not have enough time to determine whether there is an uplink channel transmission using the sTTI in the subframe where the PUSCH or the PUCCH is located before starting to transmit the uplink channel (such as the PUSCH or the PUCCH) of the 1 ms TTI length, the terminal cannot give up the use of the 1 ms TTI in time. Transmission of the upstream channel. For PUCCH format 1/1a/1b/3, there is an orthogonal sequence in the time domain. If some symbols in one slot are punctured, the orthogonality is destroyed, resulting in the punctured PUCCH pair of the terminal. The terminal generates interference in other terminals multiplexed and transmitted in the same resource block (RB). For the PUSCH, if the MU-MIMO is performed, if the puncturing position is the RS, the base station side cannot obtain the RS of the terminal, so that when the PUSCH of the other terminal that performs the MU-MIMO transmission with the terminal is received, the other terminal cannot be obtained. The PUSCH performs interference cancellation based on the RS of the terminal, thereby causing interference of data of the terminal to data of other MU-MIMO terminals.

在同一时间单元，当聚合多个载波时，在不同载波上可能传输不同TTI长度的上行信道，多个不同TTI长度的信道并行传输，可能会导致终端发射功率受限，此时需要机制避免功率受限。In the same time unit, when multiple carriers are aggregated, uplink channels of different TTI lengths may be transmitted on different carriers, and multiple channels of different TTI lengths are transmitted in parallel, which may result in limited transmission power of the terminal, and a mechanism is needed to avoid power. Limited.

例如：在同一个时间单元中在同一个载波或不同载波上同时被调度传输PDSCH和sPDSCH，或在同一个时间单元中在同一个载波或不同载波上同时存在PUCCH和sPUSCH/sPUCCH，或在同一个时间单元中在同一个载波或不同载波上同时存在PUSCH和sPUSCH/sPUCCH。由于在同一载波上为了避免较高的PAPR/CM，保证单载波特性不能重叠传输多个上行信道，在不同载波上同时传输不同TTI长度的上行信道会导致终端的发射功率受限，所以终端获得确定在时间单元i中存在第二上行信道的时间节点；和/或获得在时间单元i中第二上行信道与第一上行信道的重叠符号位置，进而，根据时间节点和/或重叠符号位置，确定在时间单元i中需要传输的上行信道，在实现保证单载波特性或避免功率受限的的目的的基础上，使得在同一时间单元在载波上传输使用不同的TTI长度的上行信道时，不影响与该信道复用传输的其他终端的传输性能。For example, the PDSCH and the sPDSCH are simultaneously scheduled to be transmitted on the same carrier or different carriers in the same time unit, or both the PUCCH and the sPUSCH/sPUCCH are present on the same carrier or different carriers in the same time unit, or in the same A PUSCH and an sPUSCH/sPUCCH are simultaneously present on the same carrier or different carriers in one time unit. In order to avoid high PAPR/CM on the same carrier, to ensure that single carrier characteristics cannot overlap multiple uplink channels, simultaneously transmitting uplink channels of different TTI lengths on different carriers may result in limited transmission power of the terminal, so the terminal obtains Determining a time node in which the second uplink channel exists in the time unit i; and/or obtaining an overlapping symbol position of the second uplink channel and the first uplink channel in the time unit i, and further, depending on the time node and/or the overlapping symbol position, Determining the uplink channel that needs to be transmitted in the time unit i, on the basis of achieving the purpose of ensuring single carrier characteristics or avoiding power limitation, when the uplink channel using different TTI lengths is transmitted on the carrier at the same time unit, Affects the transmission performance of other terminals multiplexed with the channel.

在本实施例中，在步骤：确定在时间单元i中存在使用第一传输时间间隔TTI长度传输的第一上行信道以及使用第二传输时间间隔TTI长度传输的第二上行信道之后，还包括如下步骤：In this embodiment, after determining, in the time unit i, that there is a first uplink channel transmitted using the first transmission time interval TTI length and a second uplink channel transmitted using the second transmission time interval TTI length, the following includes step:

具体的在本实施例中，如果第一上行信道和第二上行信道在不同的载波上传输。终端需要判断第一上行信道和第二上行信道的发射功率之和是否超过预设的最大发射功率，预设的最大发射功率为终端所能支持的最大发射功率。如果第一上行信道和第二上行信道的发射功率之和没有超过终端所能支持的最大发射功率，则可以在不同载波上同时传输第一上信道和第二上行信道。如果超过了终端所能支持的最大发射功率，则终端才会根据确定在时间单元i中存在第二上行信道的时间节点；和/或在时间单元i中第二上行信道与第一上行信道的重叠符号位置，确定在时间单元i中需要传输哪些上行信道。比如：根据最大发射功率的限制，对不同载波上的第一上行信道和第二上行信道中的部分上行信道进行相应打孔或取舍操作，例如按照预定的优先级选择保留优先级高的上行信道不做处理，优先打孔或丢弃低优先级的上行信道，直到满足总功率低于最大发射功率即可。优先级可以基于载波编号，载波优先级，承载的UCI，信道本身的优先级，TTI长度的优先级等某个优先级或多个优先级的组合。Specifically, in this embodiment, if the first uplink channel and the second uplink channel are transmitted on different carriers. The terminal needs to determine whether the sum of the transmit powers of the first uplink channel and the second uplink channel exceeds a preset maximum transmit power, and the preset maximum transmit power is a maximum transmit power that the terminal can support. If the sum of the transmit powers of the first uplink channel and the second uplink channel does not exceed the maximum transmit power that the terminal can support, the first upper channel and the second uplink channel may be simultaneously transmitted on different carriers. If the maximum transmit power that the terminal can support is exceeded, the terminal will determine the time node in which the second uplink channel exists in the time unit i; and/or the second uplink channel and the first uplink channel in the time unit i The overlapping symbol positions determine which upstream channels need to be transmitted in time unit i. For example, according to the limitation of the maximum transmit power, corresponding puncturing or rounding operations are performed on the first uplink channel and the second uplink channel in the second uplink channel on different carriers, for example, selecting an uplink channel with a high priority according to a predetermined priority. Without processing, priority is given to puncturing or discarding the low priority upstream channel until the total power is less than the maximum transmit power. The priority may be based on a carrier number, a carrier priority, a carried UCI, a priority of the channel itself, a priority of a TTI length, or the like, or a combination of a plurality of priorities.

进一步，本实施例中的数据传输方法，步骤：基于所述时间节点和/或所述重叠符号位置，确定在所述时间单元i中需要传输的上行信道并进行传输，在具体实施过程中可分为以下两种方法：Further, in the data transmission method in this embodiment, the step of: determining, according to the time node and/or the overlapping symbol position, an uplink channel to be transmitted in the time unit i and transmitting, in a specific implementation process, There are two ways to do this:

第一种方法：主要基于确定在时间单元i中存在第二上行信道的时间节点来确定在所述时间单元i中需要传输的上行信道并进行传输。The first method: determining an uplink channel to be transmitted in the time unit i and transmitting based on determining a time node in which the second uplink channel exists in the time unit i.

在本实施例中，所述获得确定在所述时间单元i中存在所述第二上行信道的时间节点，具体包括：In this embodiment, the determining, by using the time node that the second uplink channel exists in the time unit i, specifically includes:

具体的，当所述第二上行信道为上行共享信道时，对应所述第二上行信道的下行控制信道为传输所述第二上行信道的调度信令的下行控制信道，即UL grant，该下行控制信道使用上行DCI格式传输。当所述第二上行信道为上行控制信道时，对应所述第二上行信道的下行控制信道为需要在所述第二上行信道上进行ACK/NACK反馈的指示下行SPS资源释放的下行控制信道或调度需要在所述第二上行信道上进行ACK/NACK反馈的下行共享信道的下行控制信道，即DL grant，该下行控制信道使用下行DCI格式传输。Specifically, when the second uplink channel is an uplink shared channel, the downlink control channel corresponding to the second uplink channel is a downlink control channel for transmitting scheduling signaling of the second uplink channel, that is, a UL grant, and the downlink The control channel is transmitted using the uplink DCI format. When the second uplink channel is an uplink control channel, the downlink control channel corresponding to the second uplink channel is a downlink control channel indicating that the downlink SPS resource is released by performing ACK/NACK feedback on the second uplink channel or Scheduling a downlink control channel of a downlink shared channel that needs to perform ACK/NACK feedback on the second uplink channel, that is, a DL grant, and the downlink control channel is transmitted using a downlink DCI format.

由于所述时间节点为所述时间单元i中的时刻或所述时间节点为所述时间单元i之前的时刻，所以，在第一种方法中，根据时间节点的不同，可分为以下两种情况：Since the time node is the time in the time unit i or the time node is the time before the time unit i, in the first method, according to the time node, it can be divided into the following two types. Happening:

第一种情况：所述时间节点为所述时间单元i中的时刻，确定在所述时间单元i中需要传输的上行信道并进行传输具体可包括以下几种方式：In the first case, the time node is the time in the time unit i, and determining the uplink channel to be transmitted in the time unit i and transmitting the information may include the following methods:

方式1-1：确定在所述时间单元i中传输所述第一上行信道；即所述UE在所述时间单元i中放弃传输所述第二上行信道，仅传输所述第一上行信道。Mode 1-1: determining to transmit the first uplink channel in the time unit i; that is, the UE abandons transmitting the second uplink channel in the time unit i, and only transmits the first uplink channel.

方式1-2：判断所述重叠符号位置是否为所述第一上行信道的导频符号或承载UCI符号(其中，只需要在第一上行信道上承载了UCI时进行UCI符号判断)所在的位置；如果是，确定在所述时间单元i中传输所述第一上行信道，即放弃传输所述第二上行信道，仅传输所述第一上行信道；如果否，对所述第一上行信道中与所述第二上行信道重叠的符号进行打孔，确定在所述时间单元i中传输打孔后的第一上行信道以及所述第二上行信道。Mode 1-2: determining whether the position of the overlapping symbol is a pilot symbol of the first uplink channel or a location where a UCI symbol is carried (in which UCI symbol determination is only required when UCI is carried on the first uplink channel) If yes, determining to transmit the first uplink channel in the time unit i, that is, to abandon the transmission of the second uplink channel, to transmit only the first uplink channel; if not, to the first uplink channel The symbol overlapping with the second uplink channel is punctured, and the first uplink channel and the second uplink channel after the puncturing are transmitted in the time unit i.

其中，所述打孔即所述第一上行信道在进行信道编码和速率匹配时是考虑所述重叠符号的，在进行资源映射时，本应映射到所述重叠符号上的所述第一上行信道的信息被丢弃或者置零或被第二上行信道的信息所覆盖，在其他非重叠符号进行正常的映射和传输。The puncturing, that is, the first uplink channel is considered to be the overlapping symbol when performing channel coding and rate matching, and when performing resource mapping, the first uplink should be mapped to the overlapping symbol. The information of the channel is discarded or zeroed or covered by the information of the second upstream channel, and normal mapping and transmission are performed on other non-overlapping symbols.

具体的，在本实施例中，如图2所示，当子帧i中的PUSCH/PUCCH与在子帧i中的第一个时隙中的第6和7个符号上传输的使用sTTI为2符号长度的sPUCCH/sPUSCH在载波c上重叠时。在上述第一种情况，由于触发sPUCCH/sPUSCH传输的DL grant/UL grant的接收时间与子帧i第一个时隙的开始传输时间相隔比较近，终端在子帧i的第一个时隙开始之前不能判断在子帧i中的第一个时隙中在载波c上是否存在sPUCCH/sPUSCH，即终端在PUSCH/PUCCH在子帧i中的第一个时隙中的传输过程中才判断出在子帧i中的第一个时隙的第6和7个符号上在载波c上还存在sPUCCH/sPUSCH，此时，PUSCH/PUCCH在子帧i的第一个时隙中已经开始传输。Specifically, in this embodiment, as shown in FIG. 2, when the PUSCH/PUCCH in the subframe i and the 6th and 7th symbols in the first slot in the subframe i are used, the sTTI is used. The 2 symbol length sPUCCH/sPUSCH overlaps on the carrier c. In the first case above, since the reception time of the DL grant/UL grant for triggering the sPUCCH/sPUSCH transmission is relatively close to the start transmission time of the first slot of the subframe i, the terminal is in the first slot of the subframe i. It cannot be judged whether there is sPUCCH/sPUSCH on the carrier c in the first slot in the subframe i before the start, that is, the terminal judges during the transmission of the PUSCH/PUCCH in the first slot in the subframe i. The sPUCCH/sPUSCH is also present on the carrier c on the 6th and 7th symbols of the first slot in the subframe i. At this time, the PUSCH/PUCCH has started to be transmitted in the first slot of the subframe i. .

终端可以采用上述方式1-1，如图3所示，终端在子帧i的第一个时隙中在载波c上仅传输PUSCH/PUCCH，当然，如果第二个时隙中不存在sPUCCH/sPUSCH传输，PUSCH/PUCCH可以继续传输，如果存在sPUCCH/sPUSCH传输，按照同样方式处理，放弃传输子帧i中的第一个时隙的第6和7个符号上中在载波c上的sPUCCH/sPUSCH。The terminal may adopt the foregoing mode 1-1. As shown in FIG. 3, the terminal transmits only the PUSCH/PUCCH on the carrier c in the first time slot of the subframe i. Of course, if the sPUCCH/ does not exist in the second time slot. sPUSCH transmission, PUSCH/PUCCH may continue to be transmitted, if there is sPUCCH/sPUSCH transmission, processing in the same manner, abandoning the sPUCCH/ on the carrier c on the 6th and 7th symbols of the first slot in the transmission subframe i sPUSCH.

终端还可以采用上述方式1-2，如图4所示，终端判断sPUCCH/sPUSCH是否与PUSCH/PUCCH的导频符号重叠。如果假设子帧i中在载波c上仅存在PUSCH与sPUCCH/sPUSCH重叠，或仅存在PUCCH format 4或5与sPUCCH/sPUSCH重叠，或同时存在PUSCH以及PUCCH format 4或5与sPUCCH/sPUSCH重叠时，由于PUSCH和PUCCH format 4或5的导频在每个时隙中的第4个符号上传输，因此sPUCCH/sPUSCH与PUSCH/PUCCH的导频不重叠，终端在子帧i中的第一个时隙中在载波c上对PUSCH/PUCCH在第6和7个符号上进行打孔，即使用第一传输时间间隔TTI长度传输的上行信道在进行信道编码和速率匹配时是考虑所述重叠符号的，在进行资源映射时，将本应映射到所述重叠符号上的信息丢掉或者置零，在其他非重叠符号进行正常的映射和传输，并在第6和7个符号上在载波c上传输sPUCCH/sPUSCH。The terminal may also adopt the foregoing manner 1-2. As shown in FIG. 4, the terminal determines whether the sPUCCH/sPUSCH overlaps with the pilot symbol of the PUSCH/PUCCH. If it is assumed that only the PUSCH overlaps with the sPUCCH/sPUSCH on the carrier c in the subframe i, or only if the PUCCH format 4 or 5 overlaps with the sPUCCH/sPUSCH, or if both the PUSCH and the PUCCH format 4 or 5 overlap with the sPUCCH/sPUSCH, Since the pilots of the PUSCH and PUCCH format 4 or 5 are transmitted on the 4th symbol in each slot, the pilots of the sPUCCH/sPUSCH and the PUSCH/PUCCH do not overlap, and the terminal is in the first of the subframes i. The PUSCH/PUCCH is punctured on the 6th and 7th symbols on the carrier c, that is, the uplink channel transmitted using the first transmission time interval TTI length is considered to be the overlapping symbol when performing channel coding and rate matching. When performing resource mapping, the information that should be mapped to the overlapping symbols is discarded or zeroed, normal mapping and transmission are performed on other non-overlapping symbols, and transmitted on carrier 6 on the 6th and 7th symbols. sPUCCH/sPUSCH.

如果假设子帧i中在载波c上仅存在PUCCH format 2与sPUCCH/sPUSCH重叠，或同时存在PUSCH以及PUCCH format 2与sPUCCH/sPUSCH重叠时，由于PUCCH format 2的导频在每个时隙中的第2和6个符号上传输，因此sPUCCH/sPUSCH与PUCCH的导频重叠，则终端在子帧i的第一个时隙中在载波c上放弃传输sPUCCH/sPUSCH，仅传输PUSCH/PUCCH，传输方式如图3所示。If it is assumed that only PUCCH format 2 overlaps with sPUCCH/sPUSCH on carrier c in subframe i, or if both PUSCH and PUCCH format 2 overlap with sPUCCH/sPUSCH, the pilot of PUCCH format 2 is in each slot. The second and sixth symbols are transmitted, so that the sPUCCH/sPUSCH overlaps with the pilot of the PUCCH, the terminal abandons the transmission of the sPUCCH/sPUSCH on the carrier c in the first slot of the subframe i, and only transmits the PUSCH/PUCCH, and transmits The way is shown in Figure 3.

当子帧i中在载波c上存在承载UCI的PUSCH与sPUCCH/sPUSCH重叠时，终端进一步判断sPUCCH/sPUSCH是否与PUSCH的承载UCI的符号重叠，由于ACK/NACK映射在导频两侧的符号即第3和5个符号上，RI映射在ACK/NACK两侧的符号即第2和6个符号上，因此，在第6和7个符号上传输的sPUCCH/sPUSCH与PUSCH中承载RI的符号重叠，则终端在子帧i的第一个时隙中在载波c上放弃传输sPUCCH/sPUSCH，仅传输PUSCH，传输方式如图3所示。When the PUSCH carrying the UCI overlaps with the sPUCCH/sPUSCH on the carrier c in the subframe i, the terminal further determines whether the sPUCCH/sPUSCH overlaps with the UCI-bearing symbol of the PUSCH, because the ACK/NACK maps the symbols on both sides of the pilot. On the 3rd and 5th symbols, the RI is mapped on the 2nd and 6th symbols on both sides of the ACK/NACK, and therefore, the sPUCCH/sPUSCH transmitted on the 6th and 7th symbols overlaps with the symbol carrying the RI in the PUSCH. Then, the terminal abandons the transmission of the sPUCCH/sPUSCH on the carrier c in the first time slot of the subframe i, and transmits only the PUSCH, and the transmission mode is as shown in FIG. 3.

可选的，所述方式1-2适用于当所述第一上行信道为上行共享信道或为不使用时域正交序列的上行控制信道(例如PUCCH format 2或4或5)或所述第一上行信道承载UCI(可以是任意一种UCI，或者固定的某种UCI)时。当然，也不排除应用于除上述情况以外的所有情况，以实现所有情况统一的处理方式。Optionally, the mode 1-2 is applicable to when the first uplink channel is an uplink shared channel or an uplink control channel (eg, PUCCH format 2 or 4 or 5) that does not use a time domain orthogonal sequence. When an upstream channel carries UCI (which can be any type of UCI, or a fixed UCI). Of course, it is not excluded to apply to all cases except the above, in order to achieve a uniform processing in all cases.

第二种情况：所述时间节点为所述时间单元i之前的时刻，确定在所述时间单元i中需要传输的上行信道并进行传输具体可包括以下几种方式：The second case: the time node is the time before the time unit i, and determining the uplink channel to be transmitted in the time unit i and transmitting the information may include the following methods:

方式2-1：确定在所述时间单元i中传输所述第二上行信道；即放弃传输所述第一上行信道(即该第一上行信道在所述时间单元i中的任意时刻都不传输，即从所述时间单元i的起始时刻开始就放弃传输，但如果该第一上行信道占用多个时间单元传输，则其他时间单元中如果没有与第二上行信道重叠或不满足被放弃的情况，则可以传输)，仅传输所述第二上行信道。Mode 2-1: determining to transmit the second uplink channel in the time unit i; that is, abandon transmitting the first uplink channel (ie, the first uplink channel is not transmitted at any time in the time unit i) That is, the transmission is abandoned from the start time of the time unit i, but if the first uplink channel occupies multiple time unit transmissions, the other time units do not overlap with the second uplink channel or are not satisfied. In the case, it can be transmitted), and only the second uplink channel is transmitted.

方式2-2：确定在所述时间单元i中传输所述第一上行信道与所述第二上行信道中的上行控制信道；即放弃传输上行共享信道。Mode 2-2: determining to transmit the uplink control channel in the first uplink channel and the second uplink channel in the time unit i; that is, to abandon transmission of the uplink shared channel.

方式2-3：确定所述第一上行信道与所述第二上行信道中承载UCI的上行信道；确定在所述时间单元i中传输所述承载UCI的上行信道；如果存在多个承载UCI的上行信道，从承载UCI的上行信道中确定出承载高优先级UCI的上行信道；确定在所述时间单元i中传输所述承载高优先级UCI的上行信道；进一步，如果存在多个承载高优先级UCI的上行信道，重用上述方式2-1和/或方式2-2进行选择，放弃未被选择的上行信道。Mode 2-3: determining an uplink channel carrying the UCI in the first uplink channel and the second uplink channel; determining, in the time unit i, transmitting the uplink channel carrying the UCI; if there are multiple bearers carrying UCI Uplink channel, determining an uplink channel carrying a high priority UCI from an uplink channel carrying UCI; determining to transmit the uplink channel carrying the high priority UCI in the time unit i; further, if there are multiple bearers high priority The uplink channel of the level UCI is reused by the above mode 2-1 and/or mode 2-2 to discard the unselected uplink channel.

方式2-4：确定所述第一上行信道为上行共享信道或不使用时域正交序列的上行控制信道(例如PUCCH format 2或4或5，不排除其他后续定义的不使用时域正交序列的上行控制信道)或承载UCI(可以是任意一种UCI，或者固定的某种UCI)的上行信道；判断所述重叠符号位置是否为所述第一上行信道的导频符号或承载UCI符号所在的位置；如果是，确定在所述时间单元i中传输所述第二上行信道，即放弃传输所述第一上行信道；如果否，对所述第一上行信道中与所述第二上行信道重叠的符号进行打孔，确定在所述时间单元i中传输打孔后的第一上行信道以及所述第二上行信道。2-4: determining that the first uplink channel is an uplink shared channel or an uplink control channel that does not use a time domain orthogonal sequence (for example, PUCCH format 2 or 4 or 5, and does not exclude other subsequently defined non-use time domain orthogonal An uplink control channel of the sequence) or an uplink channel carrying a UCI (which may be any type of UCI, or a fixed UCI); determining whether the overlapping symbol position is a pilot symbol of the first uplink channel or carrying a UCI symbol a location; if yes, determining to transmit the second uplink channel in the time unit i, that is, to abandon transmitting the first uplink channel; if not, to the second uplink channel and the second uplink The symbols of the channel overlap are punctured, and it is determined that the punctured first uplink channel and the second uplink channel are transmitted in the time unit i.

具体的，在本实施例中，在第二种情况中，如图5所示，当子帧i中的PUSCH/PUCCH与在子帧i中的第一个时隙中的第1～3个符号上传输的使用sTTI为3符号长度的sPUCCH/sPUSCH在载波c上重叠时。假设由于触发sPUCCH/sPUSCH传输的DL grant/UL grant的接收时间与子帧i第一个时隙的开始传输时间相隔比较远，终端在子帧i的第一个时隙开始之前可以判断在子帧i中的第一个时隙中的第1～3个符号上在载波c上存在sPUCCH/sPUSCH。Specifically, in this embodiment, in the second case, as shown in FIG. 5, when the PUSCH/PUCCH in the subframe i and the first to third slots in the first slot in the subframe i are The sPUCCH/sPUSCH transmitted on the symbol using the sTTI of 3 symbol length overlaps on the carrier c. It is assumed that since the reception time of the DL grant/UL grant for triggering the sPUCCH/sPUSCH transmission is far from the start transmission time of the first slot of the subframe i, the terminal can judge the child before the start of the first slot of the subframe i. The sPUCCH/sPUSCH exists on the carrier c on the first to third symbols in the first slot in the frame i.

终端可以采用上述方式2-1，如图6所示，终端在子帧i中的第一个时隙中在载波c上放弃传输PUSCH/PUCCH，仅传输sPUCCH/sPUSCH，即PUSCH/PUCCH在子帧i中的第一个时隙中的任意时刻都不传输，如果第二个时隙中不存在与sTTI的重叠，则在第二个时隙中可以传输。The terminal may adopt the foregoing mode 2-1. As shown in FIG. 6, the terminal abandons the transmission of the PUSCH/PUCCH on the carrier c in the first time slot in the subframe i, and transmits only the sPUCCH/sPUSCH, that is, the PUSCH/PUCCH is in the sub-frame. No time is transmitted at any time in the first slot in frame i. If there is no overlap with sTTI in the second slot, it can be transmitted in the second slot.

终端可以采用上述方式2-2，终端在子帧i中的第一个时隙中在载波c上传输PUCCH和sPUCCH，放弃传输PUSCH和sPUSCH，如果同时存在PUCCH和sPUCCH，则进一步选择传输sPUCCH和/或选择承载高优先级UCI的信道，或者，同时传输两个信道。The terminal may adopt the foregoing manner 2-2. The terminal transmits the PUCCH and the sPUCCH on the carrier c in the first slot in the subframe i, and abandons the transmission of the PUSCH and the sPUSCH. If the PUCCH and the sPUCCH exist simultaneously, the terminal further selects to transmit the sPUCCH and / or select the channel carrying the high priority UCI, or transmit both channels simultaneously.

终端可以采用上述方式2-3，终端在子帧i中的第一个时隙中在载波c上传输承载UCI的上行信道，例如假设子帧i中存在没有承载UCI的PUSCH和承载UCI的sPUCCH，则选择传输承载UCI的sPUCCH，放弃传输没有承载UCI的PUSCH。又例如，假设子帧i中存在承载UCI的PUCCH和没有承载UCI的sPUSCH，则选择传输承载UCI的PUCCH，放弃传输没有承载UCI的sPUSCH。又例如，假设子帧i中存在PUCCH和sPUCCH，则进一步选择传输sPUCCH和/或选择承载高优先级UCI的信道，或者，同时传输两个信道。又例如，假设子帧i中存在承载UCI的PUSCH with UCI和承载UCI的sPUSCH，则进一步选择传输sPUSCH和/或选择承载高优先级UCI的信道，或者，同时传输两个信道。The terminal may adopt the foregoing manner 2-3, in which the terminal transmits the uplink channel carrying the UCI on the carrier c in the first time slot in the subframe i, for example, it is assumed that there is a PUSCH carrying the UCI and the sPUCCH carrying the UCI in the subframe i. Then, the sPUCCH carrying the UCI is selected to be transmitted, and the PUSCH that does not carry the UCI is discarded. For another example, if there is a PUCCH carrying the UCI and an sPUSCH carrying the UCI in the subframe i, the PUCCH carrying the UCI is selected to be transmitted, and the sPUSCH not carrying the UCI is discarded. For another example, assuming that PUCCH and sPUCCH are present in subframe i, the sPUCCH is further selected for transmission and/or the channel carrying the high priority UCI is selected, or both channels are simultaneously transmitted. For another example, if there is a PUSCH with UCI carrying the UCI and an sPUSCH carrying the UCI in the subframe i, the sPUSCH is further selected to be transmitted and/or the channel carrying the high priority UCI is selected, or two channels are simultaneously transmitted.

终端可以采用上述方式2-4，终端判断sPUCCH/sPUSCH是否与PUSCH/PUCCH的导频符号重叠；如果假设子帧i中在载波c上仅存在PUSCH与sPUCCH/sPUSCH重叠，或仅存在PUCCH format 4或5与sPUCCH/sPUSCH重叠，或同时存在PUSCH以及PUCCH format 4或5与sPUCCH/sPUSCH重叠时，由于PUSCH和PUCCH format 4或5的导频在每个时隙中的第4个符号上传输，因此sPUCCH/sPUSCH与PUSCH/PUCCH的导频不重叠，终端在子帧i中的第一个时隙中在载波c上对PUSCH/PUCCH在第1～3个符号上进行打孔，即所述使用第一传输时间间隔TTI长度传输的上行信道在进行信道编码和速率匹配时是考虑所述重叠符号的，在进行资源映射时，将本应映射到所述重叠符号上的信息丢掉或者置零，在其他非重叠符号进行正常的映射和传输，并在第1～3个符号上在载波c上传输sPUCCH/sPUSCH，传输方式如图7所示。The terminal may adopt the foregoing manner 2-4, the terminal determines whether the sPUCCH/sPUSCH overlaps with the pilot symbol of the PUSCH/PUCCH; if it is assumed that only the PUSCH overlaps with the sPUCCH/sPUSCH on the carrier c in the subframe i, or only the PUCCH format 4 exists Or when 5 overlaps with sPUCCH/sPUSCH, or both PUSCH and PUCCH format 4 or 5 overlap with sPUCCH/sPUSCH, since pilots of PUSCH and PUCCH format 4 or 5 are transmitted on the 4th symbol in each slot, Therefore, the sPUCCH/sPUSCH does not overlap with the pilot of the PUSCH/PUCCH, and the terminal punctured the PUSCH/PUCCH on the first to third symbols on the carrier c in the first slot in the subframe i, that is, the The uplink channel transmitted using the first transmission time interval TTI length considers the overlapping symbol when performing channel coding and rate matching, and when the resource mapping is performed, the information that should be mapped to the overlapping symbol is discarded or zeroed. Normal mapping and transmission are performed on other non-overlapping symbols, and sPUCCH/sPUSCH is transmitted on carrier c on the first to third symbols, and the transmission mode is as shown in FIG. 7.

如果假设子帧i中在载波c上仅存在PUCCH format 2与sPUCCH/sPUSCH重叠，或同时存在PUSCH以及PUCCH format 2与sPUCCH/sPUSCH重叠时，由于PUCCH format 2的导频在每个时隙中的第2和6个符号上传输，因此sPUCCH/sPUSCH与PUCCH的导频重叠，则终端在子帧i的第一个时隙中在载波c上放弃传输sPUCCH/sPUSCH，仅传输PUSCH/PUCCH，传输方式如图8所示。If it is assumed that only PUCCH format 2 overlaps with sPUCCH/sPUSCH on carrier c in subframe i, or if both PUSCH and PUCCH format 2 overlap with sPUCCH/sPUSCH, the pilot of PUCCH format 2 is in each slot. The second and sixth symbols are transmitted, so that the sPUCCH/sPUSCH overlaps with the pilot of the PUCCH, the terminal abandons the transmission of the sPUCCH/sPUSCH on the carrier c in the first slot of the subframe i, and only transmits the PUSCH/PUCCH, and transmits The way is shown in Figure 8.

第二种方法：主要基于在时间单元i中第二上行信道与第一上行信道的重叠符号位置，确定在时间单元i中需要传输的上行信道不关注在时间单元i之前，终端是否能确定存在第二上行信道。具体的，包括以下步骤：a second method: based on the overlapping symbol positions of the second uplink channel and the first uplink channel in the time unit i, determining whether the uplink channel to be transmitted in the time unit i does not care whether the terminal can determine the presence before the time unit i The second upstream channel. Specifically, the following steps are included:

其中，所述基于所述时间节点，确定在所述时间单元i中需要传输的上行信道并进行传输，具体包括：The determining, by the time node, the uplink channel that needs to be transmitted in the time unit i, and performing the transmission, specifically includes:

具体的，在本实施例中，不关注终端是否能够在子帧i的第一个时隙发送之前判断子帧i的第一个时隙中是否存在sPUCCH/sPUSCH传输，当终端确定在子帧i的第一个时隙中存在sPUCCH/sPUSCH与PUCCH/PUSCH重叠时，终端判断sPUCCH/sPUSCH是否与PUSCH/PUCCH的导频符号或承载UCI的符号重叠，具体过程同第一种方法中方式1-2，如图4所示，终端判断sPUCCH/sPUSCH是否与PUSCH/PUCCH的导频符号重叠。如果假设子帧i中在载波c上仅存在PUSCH与sPUCCH/sPUSCH重叠，或仅存在PUCCH format 4或5与sPUCCH/sPUSCH重叠，或同时存在PUSCH以及PUCCH format 4或5与sPUCCH/sPUSCH重叠时，由于PUSCH和PUCCH format 4或5的导频在每个时隙中的第4个符号上传输，因此sPUCCH/sPUSCH与PUSCH/PUCCH的导频不重叠，终端在子帧i中的第一个时隙中在载波c上对PUSCH/PUCCH在第6和7个符号上进行打孔，即使用第一传输时间间隔TTI长度传输的上行信道在进行信道编码和速率匹配时是考虑所述重叠符号的，在进行资源映射时，将本应映射到所述重叠符号上的信息丢掉或者置零，在其他非重叠符号进行正常的映射和传输，并在第6和7个符号上在载波c上传输sPUCCH/sPUSCH。Specifically, in this embodiment, it is not concerned whether the terminal can determine whether the sPUCCH/sPUSCH transmission exists in the first slot of the subframe i before the first slot of the subframe i is transmitted, when the terminal determines that the subframe is in the subframe. When the sPUCCH/sPUSCH overlaps with the PUCCH/PUSCH in the first slot of the i, the terminal determines whether the sPUCCH/sPUSCH overlaps with the pilot symbol of the PUSCH/PUCCH or the symbol carrying the UCI, and the specific process is the same as the mode 1 in the first method. -2. As shown in FIG. 4, the terminal determines whether the sPUCCH/sPUSCH overlaps with the pilot symbols of the PUSCH/PUCCH. If it is assumed that only the PUSCH overlaps with the sPUCCH/sPUSCH on the carrier c in the subframe i, or only if the PUCCH format 4 or 5 overlaps with the sPUCCH/sPUSCH, or if both the PUSCH and the PUCCH format 4 or 5 overlap with the sPUCCH/sPUSCH, Since the pilots of the PUSCH and PUCCH format 4 or 5 are transmitted on the 4th symbol in each slot, the pilots of the sPUCCH/sPUSCH and the PUSCH/PUCCH do not overlap, and the terminal is in the first of the subframes i. The PUSCH/PUCCH is punctured on the 6th and 7th symbols on the carrier c, that is, the uplink channel transmitted using the first transmission time interval TTI length is considered to be the overlapping symbol when performing channel coding and rate matching. When performing resource mapping, the information that should be mapped to the overlapping symbols is discarded or zeroed, normal mapping and transmission are performed on other non-overlapping symbols, and transmitted on carrier 6 on the 6th and 7th symbols. sPUCCH/sPUSCH.

终端判断sPUCCH/sPUSCH是否与PUSCH/PUCCH的导频符号或承载UCI的符号不重叠后，除了对第一信道进行打孔，还可以基于时间节点来确定时间单元i中需要传输的上行信道。After the terminal determines whether the sPUCCH/sPUSCH does not overlap with the pilot symbol of the PUSCH/PUCCH or the symbol carrying the UCI, in addition to puncturing the first channel, the uplink channel that needs to be transmitted in the time unit i may be determined based on the time node.

具体的，如果终端在子帧i的第一个时隙开始之前不能确定在子帧i中的第一个时隙中在载波c上存在sPUCCH/sPUSCH，终端在获知在载波c上存在sPUCCH/sPUSCH时，PUSCH/PUCCH在子帧i的第一个时隙中已经开始传输。终端确定在子帧i的第一个时隙中在载波c上仅传输PUSCH/PUCCH。Specifically, if the terminal cannot determine that the sPUCCH/sPUSCH exists on the carrier c in the first slot in the subframe i before the start of the first slot of the subframe i, the terminal knows that the sPUCCH/ exists on the carrier c. At sPUSCH, the PUSCH/PUCCH has started transmission in the first slot of subframe i. The terminal determines that only the PUSCH/PUCCH is transmitted on carrier c in the first slot of subframe i.

如果终端在子帧i的第一个时隙开始之前能确定在子帧i中的第一个时隙中在载波c上存在sPUCCH/sPUSCH，终端可以在子帧i中的第一个时隙中在载波c上放弃传输PUSCH/PUCCH，仅传输sPUCCH/sPUSCH，即PUSCH/PUCCH在子帧i中的第一个时隙中的任意时刻都不传输，如果第二个时隙中不存在与sTTI的重叠，则在第二个时隙中可以传输。If the terminal can determine that there is an sPUCCH/sPUSCH on the carrier c in the first slot in the subframe i before the start of the first slot of the subframe i, the terminal may be in the first slot in the subframe i Transmitting the PUSCH/PUCCH on the carrier c, and transmitting only the sPUCCH/sPUSCH, that is, the PUSCH/PUCCH is not transmitted at any time in the first slot in the subframe i, if the second slot does not exist and The overlap of sTTIs can be transmitted in the second time slot.

或者，终端在子帧i中的第一个时隙中在载波c上传输PUCCH和sPUCCH，放弃传输PUSCH和sPUSCH，如果同时存在PUCCH和sPUCCH，则进一步选择传输sPUCCH和/或选择承载高优先级UCI的信道，或者，同时传输两个信道。Alternatively, the terminal transmits the PUCCH and the sPUCCH on the carrier c in the first time slot in the subframe i, abandoning the transmission of the PUSCH and the sPUSCH, and if the PUCCH and the sPUCCH exist simultaneously, further selecting the transmission sPUCCH and/or selecting the bearer high priority The channel of the UCI, or both channels are transmitted simultaneously.

或者，终端在子帧i中的第一个时隙中在载波c上传输承载UCI的上行信道，例如假设子帧i中存在没有承载UCI的PUSCH和承载UCI的sPUCCH，则选择传输承载UCI的sPUCCH，放弃传输没有承载UCI的PUSCH。又例如，假设子帧i中存在承载UCI的PUCCH和没有承载UCI的sPUSCH，则选择传输承载UCI的PUCCH，放弃传输没有承载UCI的sPUSCH。又例如，假设子帧i中存在PUCCH和sPUCCH，则进一步选择传输sPUCCH和/或选择承载高优先级UCI的信道，或者，同时传输两个信道。又例如，假设子帧i中存在承载UCI的PUSCH和承载UCI的sPUSCH，则进一步选择传输sPUSCH和/或选择承载高优先级UCI的信道，或者，同时传输两个信道。Alternatively, the terminal transmits the uplink channel carrying the UCI on the carrier c in the first time slot in the subframe i. For example, if there is a PUSCH carrying the UCI and the sPUCCH carrying the UCI in the subframe i, the terminal is selected to transmit the UCI. sPUCCH, abandoning the transmission of a PUSCH that does not carry UCI. For another example, if there is a PUCCH carrying the UCI and an sPUSCH carrying the UCI in the subframe i, the PUCCH carrying the UCI is selected to be transmitted, and the sPUSCH not carrying the UCI is discarded. For another example, assuming that PUCCH and sPUCCH are present in subframe i, the sPUCCH is further selected for transmission and/or the channel carrying the high priority UCI is selected, or both channels are simultaneously transmitted. For another example, if there is a PUSCH carrying the UCI and an sPUSCH carrying the UCI in the subframe i, the sPUSCH is further selected to be transmitted and/or the channel carrying the high priority UCI is selected, or two channels are simultaneously transmitted.

进一步，由于采用上述传输方式，会导致第一上行信道和/或第二上行信道中部分上行信道未被传输或被打孔，如果未被传输或被打孔的上行信道上承载UCI，需要对未被传输或被打孔的上行信道上承载UCI进行转移，所以，在步骤：基于所述时间节点和/或所述重叠符号位置，确定在所述时间单元i中需要传输的上行信道并进行传输之后，本实施例中方法还如下步骤：Further, due to the foregoing transmission mode, some uplink channels in the first uplink channel and/or the second uplink channel are not transmitted or punctured.
