技术领域Technical field

本发明涉及无线通信技术领域，特别涉及一种数据传输指示、处理方法及装置。The present invention relates to the field of wireless communication technologies, and in particular, to a data transmission indication, processing method, and apparatus.

背景技术Background technique

在长期演进(Long Term Evolution，LTE)***中引入短传输时间间隔(Transmission Time Interval，TTI)后，会出现短TTI数据和1ms TTI数据在同一子帧同一载波同时传输的问题。After a short transmission time interval (TTI) is introduced in a Long Term Evolution (LTE) system, a problem occurs in that short TTI data and 1 ms TTI data are simultaneously transmitted on the same carrier in the same subframe.

图1为常规时延终端1和低时延终端2在同一子帧同一载波同时调度示意图，如图1，基站在子帧n传输UL grant_1(上行调度信息)调度一个终端1在子帧n+4进行物理上行链路共享信道(Physical Uplink Shared Channel，PUSCH)传输，此时有一个低时延终端2在子帧n+k有上行传输的需求，或者终端1在子帧n+k上有上行短TTI传输的需求，于是在子帧n+3内，基站又发送了UL grant_2调度低时延终端2或者终端1在子帧n+k传输短PUSCH(shortened PUSCH)。若没有额外可用的资源供终端2调度，则终端1的发送数据和短TTI数据发生冲突。1 is a schematic diagram of simultaneous scheduling of the same carrier in the same subframe of the conventional delay terminal 1 and the low latency terminal 2, as shown in FIG. 1, the base station transmits UL grant_1 (uplink scheduling information) in subframe n to schedule one terminal 1 in subframe n+ 4 performing Physical Uplink Shared Channel (PUSCH) transmission. At this time, there is a low-latency terminal 2 having an uplink transmission requirement in the subframe n+k, or the terminal 1 has a sub-frame n+k. The uplink short TTI transmission is required, and then in the subframe n+3, the base station transmits the UL grant_2 scheduling low latency terminal 2 or the terminal 1 transmits the short PUSCH (shortened PUSCH) in the subframe n+k. If there is no additional available resources for the terminal 2 to schedule, the transmission data of the terminal 1 and the short TTI data collide.

也即，现有技术的不足在于，当短TTI数据和1ms TTI数据在同一子帧同一载波同时传输时，短TTI数据和1ms TTI数据会产生冲突，然而，目前没有方案能够避免这一问题。That is, the shortcoming of the prior art is that when the short TTI data and the 1 ms TTI data are simultaneously transmitted on the same carrier in the same subframe, the short TTI data and the 1 ms TTI data may collide, however, there is currently no solution to avoid this problem.

具体实施方式detailed description

随着移动通信业务需求的发展变化，国际电信联盟(International Telecommunication Union，ITU)等多个组织对未来移动通信***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长度。但发明人在发明过程中注意到：With the development of mobile communication services, organizations such as the International Telecommunication Union (ITU) have defined higher user plane delay performance requirements for future mobile communication systems. One of the main ways to reduce user latency performance is to reduce the length of the transmission interval. But the inventor noticed during the invention:

引入短TTI后，会出现短TTI数据和1ms数据终端在同一子帧同一载波同时传输的问题，解决方法之一是将1ms TTI的数据在冲突的资源位置上打孔，不发射已经准备好的数据，称为打孔(puncture)方法。但是，在现有LTE***中，基站没有专门指示终端1进行puncture的通知信令和处理过程。当终端1不做puncture，1ms TTI数据和shortened TTI(短TTI)数据产生冲突，对1ms TTI数据和shortened TTI数据的传输性能均会造成影响。After the introduction of the short TTI, there is a problem that the short TTI data and the 1 ms data terminal are transmitted simultaneously on the same carrier in the same subframe. One of the solutions is to punch the 1 ms TTI data in the conflicting resource location, and the transmission is not ready. Data, called the puncture method. However, in the existing LTE system, the base station does not specifically indicate the notification signaling and processing procedure of the terminal 1 for the puncture. When terminal 1 does not perform puncture, the 1ms TTI data and the shortened TTI (short TTI) data conflict, which affects the transmission performance of 1ms TTI data and shortened TTI data.

也即，目前并没有明确的基站指示终端进行1ms TTI数据的进行puncture以及指示puncture资源位置的具体方案。基于此，本发明实施例中提出了一种解决短TTI数据和1ms TTI数据产生冲突的方案。下面结合附图对本发明的具体实施方式进行说明。That is, there is currently no clear base station instructing the terminal to perform a puncture of 1 ms TTI data and a specific scheme indicating the location of the puncture resource. Based on this, in the embodiment of the present invention, a solution for conflicting between short TTI data and 1 ms TTI data is proposed. Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

在说明过程中，将分别从基站侧与终端侧的实施进行说明，同时还将分别对上行与下行的实施进行说明。然后还将给出二者配合在上行与下行实施的实例以更好地理解本发明实施例中给出的方案的实施。但这样的说明方式并不意味着二者必须配合实施、或者必须单独实施，实际上，当终端与基站分开实施时，其也各自解决终端侧、基站侧的问题，而二者结合使用时，会获得更好的技术效果。 In the description process, the implementations from the base station side and the terminal side will be described separately, and the implementation of the uplink and downlink will be described separately. An example in which both are implemented in the uplink and downlink will also be given to better understand the implementation of the solution presented in the embodiments of the present invention. However, such an explanation does not mean that the two must be implemented together or must be implemented separately. In fact, when the terminal is separately implemented from the base station, it also solves the problems on the terminal side and the base station side, and when the two are combined, Will get better technical results.

还需要说明的是，由于基站侧与终端侧的行为一般是对应的，以及本申请中上行与下行的实施也有对应的部分，因此出于简明的要求将以基站一侧、以及上行为主进行说明，但这不意味着未进行说明的另一侧以及下行没有相应的实施，本领域技术人员应当能够根据常识明了相应的一侧以及下行的实施。It should be noted that since the behaviors of the base station side and the terminal side generally correspond, and the implementation of the uplink and downlink in the present application also has corresponding parts, the base station side and the uplink are mainly performed for the sake of brevity. It should be noted that this does not mean that the other side and the downlink are not implemented, and those skilled in the art should be able to understand the corresponding side and the implementation of the downlink according to common knowledge.

下面结合附图对本发明的具体实施方式进行说明。Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

图2为基站侧上行数据传输指示方法实施流程示意图，如图所示，可以包括：2 is a schematic flowchart of an implementation process of an uplink data transmission indication method on a base station side, as shown in the figure, which may include:

步骤201、在基站侧向终端发送第一上行调度信息(以下为描述方便，称为UL grant_1)用以调度一个使用第一TTI长度进行上行传输的PUSCH；Step 201: Send, by the base station, the first uplink scheduling information (hereinafter referred to as UL grant_1) to schedule a PUSCH that uses the first TTI length for uplink transmission.

步骤202、在发送UL grant_1后，向终端发送上行通知信令用以指示终端根据该上行通知信令在所述使用第一TTI长度进行上行传输的PUSCH上执行puncture。Step 202: After transmitting the UL grant_1, send the uplink notification signaling to the terminal, to instruct the terminal to perform a puncture on the PUSCH that uses the first TTI length for uplink transmission according to the uplink notification signaling.

(In order to better understand the implementation, facilitate the expression, and do not cause ambiguity, the uplink notification letter is also used in the embodiment of the present application. The command is called notification signaling P), and the notification signaling is used by the terminal to determine which part of the PUSCH transmitted using the first TTI length is puncture.

具体实施中，一种情况可以是，不论是否需要puncturing，基站都会发送通知信令P，如果不需要puncturing，则指示内容表达不需要puncturing，如果需要puncturing，则指示内容为puncturing资源，此时通知信令可以单播也可以组播，则此时UL grant2的行为或者基站确定是否重叠的行为可以是进一步的选择；In a specific implementation, a situation may be that the base station sends a notification signaling P whether or not puncturing is required. If puncturing is not required, the content expression does not need to be puncturing, and if puncturing is required, the content is puncturing resources, and the notification is notified. The signaling may be unicast or multicast, and the behavior of the UL grant 2 or the behavior of the base station determining whether to overlap may be a further option;

另一种情况可以是，只有在需要puncturing时基站才发送通知信令P，此时通知信令只能是单播，UL grant2的行为或者基站确定是否重叠的行为则是发送通知信令的时先做的处理。In another case, the base station sends the notification signaling P only when puncturing is required. At this time, the notification signaling can only be unicast, and the behavior of the UL grant 2 or the behavior of the base station determining whether to overlap is the time when the notification signaling is sent.

Specifically, the notification signaling P can be carried in the downlink control channel, for example, using Downlink Control Information (DCI) format of a downlink control channel, and can carry notification information of one or more terminals.

实施中，所述上行通知信令在legacy(传统)控制区域发送或者在用于调度第二TTI长度传输的PUSCH的控制区域发送。In implementation, the uplink notification signaling is sent in a legacy control region or in a control region of a PUSCH for scheduling a second TTI length transmission.
