- eMBB Enhanced Mobile Broad Band
- mMTC Massive Machine Type Communications
- URLLC High Reliability Low Delay
- the three types of scenarios are different for the type of business, and the requirements are different.
- the eMBB service is mainly for a service scenario that requires a higher data rate
- the mMTC service is mainly for a large number of connected service scenarios
- the URLLC service is mainly for a service scenario with a delay requirement and a high reliability.
- the new wireless technology (English: New Radio, NR), because it wants to support multiple services at the same time, such as the diversity multiplexing of eMBB services and URLLC services.
- the phenomenon that the diversity multiplexing may cause is to allocate one resource block (Resource Block, RB) of one slot to the UE#1 of the eMBB, and the first device In slot1, the data and control signaling related to the UE#1 are configured to be sent.
- the UE#2 of the URL1 in the middle of the slot1 suddenly has a service, the UE needs to allocate resources to the UE#2 of the URLLC in order to meet the delay requirement of the URLLC service.
- the middle one CB allocates resources for the UE#2 of the URLLC, but transmits the data or control signaling of the UE#2 of the URLLC.
- the UE#1 of the eMBB does not know the information of the resources occupied by the UE of the URLLC, thus affecting the efficiency and correct rate of data demodulation.

- the specific embodiments of the present invention are not limited to the above terminal representation.
- the present invention is not limited to the execution of the terminal and other terminals.
- the terminal performs the eMBB service, and the other terminals perform the URLLC service. It should be noted that there may be multiple other terminals.
- the first aspect of the present invention provides a data processing method for solving a problem that a base station allocates time-frequency resources for a terminal, and in order to improve resource usage efficiency and meet delay requirements of other terminals, the base station will partially allocate time-frequency resources of the terminal.
- the resources are allocated to other terminals, and the terminal does not know the information occupied by other terminals, resulting in the problem of low efficiency and low accuracy of data demodulation.
- a data processing method includes:
- Step S102 The terminal acquires the indication information sent by the base station.
- the indication information is used to indicate that the terminal identifies the information of the second time-frequency resource. That is, the terminal can obtain the information of the second time-frequency resource occupied by the other terminal by acquiring the indication information, so that the data corresponding to the second time-frequency resource may not be demodulated when demodulating the data transmitted by the first time-frequency resource, thereby improving the data. The efficiency and correct rate of demodulation.
- the second time-frequency resource is that the base station allocates part of the time-frequency resources in the first time-frequency resource that has been allocated to the terminal to the time-frequency resources of other terminals. That is, the base station allocates time-frequency resources allocated to other terminals in the first time-frequency resource of the terminal as the second time-frequency resource, in order to satisfy the multi-service multiplexing. As shown in FIG. 1, the resource occupied by the URLLC service is used as the second time-frequency resource.
- the indication information is located in a symbol of a control channel in which a transmission time interval (TTI) of the second time-frequency resource is located, and the terminal acquires the indication information sent by the base station, where the terminal includes: Obtaining the indication information in the symbol of the control channel where the TTI is located in the transmission time interval of the frequency resource, or the indication information is located in the control channel of the last N TTIs of the TTI of the first time-frequency resource, and the terminal acquires the indication information sent by the base station, specifically including The terminal acquires indication information in a control channel of the last N TTIs of the TTI of the first time-frequency resource, where N is an integer greater than or equal to 1.
- TTI transmission time interval
- the indication information may be in a symbol in which the control channel of the TTI of the second time-frequency resource is located, or in a control channel of the last N TTIs of the TTI of the first time-frequency resource. That is to say, when receiving the control signaling and data sent by the base station, the terminal first needs to monitor the location of the indication information that may appear in the control channel, and after receiving the location of the indication information, obtain the indication information.
- the method further includes: receiving, by the terminal, radio resource control (RRC) signaling sent by the base station, where the RRC signaling is used to indicate that the terminal is from the first time
- RRC radio resource control
- the indication information is obtained in a symbol in which the control channel of the last N TTIs of the TTI of the frequency resource or the control channel of the TTI of the second time-frequency resource is located.
- the terminal can obtain the location information of the indication information according to the RRC signaling, thereby improving the efficiency of acquiring the indication information and reducing the power consumption of the terminal.
- the time domain granularity of the indication information is a microslot level or a symbol level. That is to say, the time domain granularity of the indication information may be a minislot mini-slot level or a symbol level. Since the time domain granularity at the microslot level is larger than the time domain granularity at the symbol level, the flexibility of data decoding is further improved, and power consumption is reduced.
- the time domain granularity of the indication information is a microslot level; when the second time-frequency resource is a symbol length in the time domain, the indication information The time domain granularity is the symbol level.
- the time-domain granularity transmission indication information of the mini-slot level is used, and the second time-frequency resource is one in the time domain.
- the indication information is transmitted at the symbol level of the time domain granularity. Since the time domain granularity at the microslot level is larger than the time domain granularity at the symbol level, signaling overhead is reduced.
- the control information occupies one symbol. If the indication information is transmitted at the symbol level, 6 bits are required to indicate, wherein the feedback character is 0 means no use, and the feedback character is 1 means use; and if the second time-frequency resource is 2 symbols in the time domain, the micro-slot level is used. For the time domain granularity transmission indication information, 5 bits are required to indicate, thereby reducing signaling overhead.
- Step S104 The terminal skips the second time-frequency resource according to the indication information, and performs data decoding on the data transmitted by the resources other than the second time-frequency resource in the first time-frequency resource.
- This embodiment does not limit the specific data decoding process.
- the information about the second time-frequency resource is included in the indication information, and the terminal only needs to decode the data transmitted by the resources other than the second time-frequency resource in the first time-frequency resource when decoding the data, without decoding.
- the data transmitted by the second time-frequency resource thereby improving the efficiency and correct rate of data demodulation.
- a data processing method includes:
- Step S202 The base station allocates the second time-frequency resource in the first time-frequency resource that has been allocated to the terminal to the other terminal, and generates indication information according to the second time-frequency resource.
- the second time-frequency resource is that the base station allocates part of the time-frequency resources in the first time-frequency resource that has been allocated to the terminal to the time-frequency resources of other terminals. That is, the base station allocates time-frequency resources allocated to other terminals in the first time-frequency resource of the terminal as the second time-frequency resource, in order to satisfy the multi-service multiplexing. As shown in FIG. 1, the resource occupied by the URLLC service is used as the second time-frequency resource.
- the indication information is generated according to the second time-frequency resource.
- the information of the second time-frequency resource can be identified, and the terminal only needs to decode the data transmitted by the resources other than the second time-frequency resource in the first time-frequency resource when performing data decoding, without The data transmitted by the second time-frequency resource is decoded, thereby improving the efficiency and correct rate of data demodulation.
- the base station sends the radio resource control RRC signaling to the terminal, where the RRC signaling is used to indicate the control channel of the last N TTIs of the TTI of the first time-frequency resource or the TTI of the second time-frequency resource. Get the indication information in the symbol where you are.
- the terminal can obtain the location information of the indication information according to the RRC signaling, thereby improving the efficiency of acquiring the indication information and reducing the power consumption of the terminal.
- the time domain granularity of the indication information is a microslot level or a symbol level. That is to say, the time domain granularity of the indication information may be a minislot mini-slot level or a symbol level. Since the time domain granularity at the microslot level is larger than the time domain granularity at the symbol level, the flexibility of data decoding is further improved, and power consumption is reduced.
- the time domain granularity of the indication information is a microslot level; when the second time-frequency resource is a symbol length in the time domain, the indication information The time domain granularity is the symbol level.
- the time-domain granularity transmission indication information of the mini-slot level is used, and the second time-frequency resource is one in the time domain.
- the indication information is transmitted at the symbol level of the time domain granularity. Since the time domain granularity at the microslot level is larger than the time domain granularity at the symbol level, the flexibility of data decoding is further improved, and power consumption is reduced.
- Step S204 The base station sends the indication information to the terminal.
- the base station sends the indication information for indicating the second time-frequency resource to the terminal. Because the indication information includes the information of the second time-frequency resource, the terminal only needs to decode the first time-frequency resource except the second when performing data decoding. The data transmitted by other resources than the time-frequency resource can be used without decoding the data transmitted by the second time-frequency resource, thereby improving the efficiency and correct rate of data demodulation.
- the base station may configure the indication information in a symbol of the control channel of the TTI of the second time-frequency resource, and carry the indication information in the downlink control information DCI to be sent to the terminal; the base station may also send the indication information.
- Configured in the control channel of the last N TTIs of the TTI of the first time-frequency resource, and passes the new radio physical downlink control channel (NR-PDCCH) or the intra-group physical downlink control channel (English: New Radio Physical Downlink Control Channel, NR-PDCCH) : group common Physical Downlink Control Channel, group common PDCCH) transmits indication information, where N is an integer greater than or equal to 1.
- the location of the indication information is shown in FIG. 4, and the indication information sent by the base station to the terminal may be the first indication information or the second indication information shown in FIG. 4, where the first indication information is occupied by the URLLC1 service.
- the information indicating the time-frequency resource occupied by the URLLC1 service is sent to the terminal by the time-frequency resource assigned to the URLLC1, and the terminal can demodulate the URLLC1.
- the second indication information In the control channel of the TTI of the next eMBB service, the information indicating the time-frequency resource occupied by the URLLC2 service, that is, the control channel of the last N TTIs of the TTI of the first time-frequency resource, can be solved in the second time.
- the frequency resource does not support the problem of sending the indication information, and the pressure of the second time-frequency resource to send the indication information can be alleviated, and the terminal can skip the second time-frequency resource by using the indication information.
- Data decoding is performed on data transmitted by resources other than the second time-frequency resource in the first time-frequency resource, thereby improving the efficiency and accuracy of data demodulation.
- the location of the indication information may be determined by a service support capability of the terminal, a service level of the terminal performing the service, and an occupation ratio between the second time-frequency resource and the first time-frequency resource, and may further include other determining manners.

为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其它的附图。
其中：

图2为本发明实施例提供的一种数据处理方法的流程示意图；
图3为本发明实施例提供的另一种数据处理方法的流程示意图；
图4为本发明实施例提供的一种不同指示信息的位置示意图；

图8为一个实施例中运行数据处理方法的计算机设备的结构示意图。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
现有长期演进(英文：Long Term Evolution，LTE)情况下，数据发送都是以传输块(英文：transport block，TB)为单位。其中TB可包括多个码块(英文：code block，CB)，CB为TB的发送基本单元。
目前第五代通信主要场景包括以下三种：增强的移动宽带(英文：enhanced Mobile Broad Band，eMBB)，大量机器类通信(英文：massive Machine Type Communications，mMTC)和高可靠低时延(英文：Ultra-Reliable and Low Latency Communications，URLLC)。而这三种场景所针对的业务类型不一样，其需求也不一样。比如eMBB业务主要是针对需要较高的数据速率的业务场景；mMTC业务主要是针对大量连接的业务场景；URLLC业务主要是针对时延要求以及可靠性较高的业务场景。
在新的无线技术(英文：New Radio，NR)中，因为要同时支持多种业务，比如eMBB业务和URLLC业务的分集复用。为提高资源使用效率和满足URLLC业务的时延需求，该分集复用可能导致的现象是给eMBB的UE#1分配了1个slot的N个资源块(Resource Block，RB)，且第一设备在slot1中配置发送与UE#1相关的数据和控制信令，当slot1中间URLLC的UE#2突然有业务到达，那么为了满足URLLC业务的时延要求，需要立刻给URLLC的UE#2分配资源，那么就可能将slot中间的部分符号分配给URLLC的UE#2，即这N个RB的全部或者部分在这部分符号时间时不再传送eMBBUE#1的数据或控制信令(如图1所示，中间一个CB为URLLC的UE#2分配资源)，而是发送URLLC的UE#2的数据或控制信令。然而URLLC的UE占用eMBB的资源之后，eMBB的UE#1并不知道被URLLC的UE占用的资源的信息，因此影响数据解调的效率和正确率。
在本实施例中，终端具体可以为：个人计算机、服务器计算机、手持式或膝上型、消费型电子设备、移动设备(比如智能手机、平板电脑、媒体播放器等等)和多处理器系统等等，当然也可以为：基站。本发明具体实施方式并不局限上述终端表现形式。
本发明对于终端和其他终端的执行业务不作限定，优选的为终端执行eMBB业务，其他终端执行URLLC业务。需要说明的是，其他终端可以有多个。
基于此，本发明第一方面提供一种数据处理方法用于解决基站为终端分配时频资源后，为了提高资源使用效率和满足其它终端的时延需求，基站在终端的时频资源上将部分资源分配给其他终端，而终端并不知道被其他终端占用资源的信息，造成数据解调的效率和正确率低的问题。具体的，如图2所示，一种数据处理方法，包括：
步骤S102：终端获取基站下发的指示信息。
在本实施例中，指示信息用于指示终端识别第二时频资源的信息。即终端通过获取指示信息可获取其他终端占用的第二时频资源的信息，这样在解调第一时频资源传输的数据时可以不解调第二时频资源对应的数据，从而提高了数据解调的效率和正确率。
在本实施例中，第二时频资源为基站将已分配给终端的第一时频资源中的部分时频资源分配给其他终端的时频资源。也就是说，基站为了满足多业务复用，将终端的第一时频资源中为其他终端分配的时频资源作为第二时频资源。如图1所示，将URLLC业务所占用的资源作为第二时频资源。
可选的，指示信息位于第二时频资源的传输时间间隔(英文：Transmission Time Interval，TTI)的控制信道所在的符号中，终端获取基站下发的指示信息，具体包括：终端在第二时频资源的传输时间间隔TTI的控制信道所在的符号中获取指示信息，或指示信息位于第一时频资源的TTI的后N个TTI的控制信道中，终端获取基站下发的指示信息，具体包括：终端在第一时频资源的TTI的后N个TTI的控制信道中获取指示信息，N为大于等于1的整数。
在本实施例中，指示信息可在第二时频资源的TTI的控制信道所在的符号中，也可在第一时频资源的TTI的后N个TTI的控制信道中。也就是说，终端在接收基站下发的控制信令和数据时，先要监听控制信道中可能出现的指示信息的位置，当监听到指示信息的位置后，获取指示信息。
优选的，终端获取基站下发的指示信息的步骤之前，还包括：终端接收基站下发的无线资源控制(英文：Radio Resource Control，RRC)信令，RRC信令用于指示终端从第一时频资源的TTI的后N个TTI的控制信道或第二时频资源的TTI的控制信道所在的符号中获取指示信息。
也就是说，终端根据RRC信令即可获取指示信息的位置信息，从而提高了获取指示信息的效率，并降低终端的功耗。
优选的，指示信息的时域粒度为微时隙级别或符号级别。也就是说，指示信息的时域粒度可为微时隙mini-slot级别，也可以为符号级别。由于微时隙级别的时域粒度大于符号级别的时域粒度，从而进一步提高数据解码的灵活性，并降低功耗。
具体的，当第二时频资源在时域上大于或等于两个符号时，指示信息的时域粒度为微时隙级别；当第二时频资源在时域上为一个符号长度，指示信息的 时域粒度为符号级别。
也就是说，当第二时频资源在时域上大于或等于两个符号时，采用微时隙mini-slot级别的时域粒度传输指示信息，而第二时频资源在时域上为一个符号时，采用符号级别的时域粒度传输指示信息。由于微时隙级别的时域粒度大于符号级别的时域粒度，从而减少信令开销。
举例来说，假设TTI中共有7个符号，控制信息占用一个符号。若以符号级别传输指示信息，需要6bit来指示，其中，反馈字符为0表示不用，反馈字符为1表示使用；而第二时频资源在时域若为2个符号，则以微时隙级别为时域粒度传输指示信息，需要5bit来指示，从而减少信令开销。
步骤S104：终端根据指示信息跳过第二时频资源，对第一时频资源中除第二时频资源以外的其他资源所传输的数据进行数据解码。
本实施例对于具体的数据解码过程不作限定。
由于指示信息中包含第二时频资源的信息，则终端在进行数据解码时只需解码第一时频资源中除第二时频资源以外的其他资源所传输的数据即可，而不需要解码第二时频资源所传输的数据，从而提高数据解调的效率和正确率。
本发明第二方面提供另一种数据处理方法，请参照图3，如图3所示，一种数据处理方法，包括：
步骤S202：基站将已分配给终端的第一时频资源中的第二时频资源分配给其他终端，根据第二时频资源生成指示信息。
在本实施例中，第二时频资源为基站将已分配给终端的第一时频资源中的部分时频资源分配给其他终端的时频资源。也就是说，基站为了满足多业务复用，将终端的第一时频资源中为其他终端分配的时频资源作为第二时频资源。如图1所示，将URLLC业务所占用的资源作为第二时频资源。
在本实施例中，指示信息是根据第二时频资源生成的。根据指示信息终端就可以识别第二时频资源的信息，终端在进行数据解码时只需解码第一时频资源中除第二时频资源以外的其他资源所传输的数据即可，而不需要解码第二时频资源所传输的数据，从而提高了数据解调的效率和正确率。
优选的，基站将无线资源控制RRC信令下发给终端，RRC信令用于指示终端从第一时频资源的TTI的后N个TTI的控制信道或第二时频资源的TTI的控制信道所在的符号中获取指示信息。
也就是说，终端根据RRC信令即可获取指示信息的位置信息，从而提高了获取指示信息的效率，并降低终端的功耗。
优选的，指示信息的时域粒度为微时隙级别或符号级别。也就是说，指示信息的时域粒度可为微时隙mini-slot级别，也可以为符号级别。由于微时隙级别的时域粒度大于符号级别的时域粒度，从而进一步提高数据解码的灵活性，并降低功耗。
具体的，当第二时频资源在时域上大于或等于两个符号时，指示信息的时域粒度为微时隙级别；当第二时频资源在时域上为一个符号长度，指示信息的时域粒度为符号级别。
也就是说，当第二时频资源在时域上大于或等于两个符号时，采用微时隙mini-slot级别的时域粒度传输指示信息，而第二时频资源在时域上为一个符号时，采用符号级别的时域粒度传输指示信息。由于微时隙级别的时域粒度大于符号级别的时域粒度，从而进一步提高数据解码的灵活性，并降低功耗。
步骤S204：基站将指示信息下发给终端。
基站将用于指示第二时频资源的指示信息下发给终端，由于指示信息中包含第二时频资源的信息，则终端在进行数据解码时只需解码第一时频资源中除第二时频资源以外的其他资源所传输的数据即可，而不需要解码第二时频资源所传输的数据，从而提高了数据解调的效率和正确率。
可选的，基站可以将指示信息配置在第二时频资源的TTI的控制信道所在的符号中，并将指示信息携带在下行链路控制信息DCI中下发给终端；基站也可以将指示信息配置在第一时频资源的TTI的后N个TTI的控制信道中，并通过新空口物理下行控制信道(英文：New Radio Physical Downlink Control Channel，NR-PDCCH)或组内物理下行控制信道(英文：group common Physical Downlink Control Channel，group common PDCCH)传输指示信息，N为大于等于1的整数。
图4中示出了指示信息的位置，基站下发给终端的指示信息可以是图4所示的第一指示信息也可以是第二指示信息，其中，第一指示信息是位于URLLC1业务占用的第二时频资源的TTI的控制信道所在的符号中，用于指示URLLC1业务占用的时频资源的信息，将指示信息跟随分配给URLLC1时频资源下发给终端，则终端可在解调URLLC1业务占用的时频资源所传输的数据之前，获取指示信息，从而不需要对URLLC1业务占用的时频资源所传输的数据进行解调，提高了数据解调的效率和正确率；第二指示信息是位于下一个eMBB业务的TTI的控制信道中，用于指示URLLC2业务占用的时频资源的信息，也就是第一时频资源的TTI的后N个TTI的控制信道中，可解决第二时频资源不支持下发指示信息的问题，此外也可缓解第二时频资源下发指示信息的压力，终端通过指示信息可跳过第二时频资源，对第一时频资源中除第二时频资源以外的其他资源所传输的数据进行数据解码，提高了数据解调的效率和正确率。
可选的，指示信息的位置可通过终端的业务支持能力、终端的执行业务的业务等级和第二时频资源与第一时频资源之间的占用比来确定，此外可能还包括其它确定方式，本发明实施例不作限定。
其中，当终端支持其他终端的业务时，基站通过第二时频资源的TTI的控制信道所在的符号下发指示信息，或基站通过第一时频资源的TTI的后N个TTI 的控制信道下发指示信息；当终端不支持其他终端的业务时，基站通过第一时频资源的TTI的后N个TTI的控制信道下发指示信息。
由于终端必然支持终端的业务，当终端支持其他终端的业务时，指示信息通过DCI或复用NR-PDCCH或PDCCH传输给终端，则终端在第二时频资源的TTI的控制信道所在的符号中或第一时频资源的TTI的后N个TTI的控制信道中获取指示信息。而终端不支持其他终端的业务时，指示信息只能复用NR-PDCCH或PDCCH传输给终端，则终端在第一时频资源的TTI的后N个TTI中获取指示信息。
其中，当终端的执行业务的业务等级高于或等于等级阈值时，基站通过第二时频资源的TTI的控制信道所在的符号下发指示信息；当终端的执行业务的业务等级低于等级阈值时，基站通过第二时频资源的TTI的控制信道所在的符号下发指示信息，或基站通过第一时频资源的TTI的后N个TTI的控制信道下发指示信息。
在本实施例中，业务等级的确定因素至少包括终端的执行业务的时延需求。根据终端的执行业务的时延需求确定业务等级，其中，业务时延需求越高业务等级越高。此外还可包括其它确定因素，对于业务等级的确定因素本发明不作限定。
也就是说，当终端的执行业务的业务等级高于或等于等级阈值时，为了提高数据解调的效率和正确率，指示信息通过DCI传输给终端，则终端在第二时频资源的TTI的控制信道所在的符号中获取指示信息。而业务等级低于等级阈值时，指示信息可通过DCI传输给终端，也可通过复用NR-PDCCH或PDCCH传输给终端，则终端在第一时频资源的TTI的后N个TTI的控制信道中获取指示信息。
需要说明的是，本实施例对于终端和其他终端的执行业务不作限定。但优选的是，终端执行eMBB业务，其他终端执行URLLC业务。也就是说，终端的执行业务的业务等级是eMBB业务的业务等级。
其中，确定第二时频资源与第一时频资源之间的占用比；当占用比小于或等于占用阈值时，基站通过第二时频资源的TTI的控制信道所在的符号下发指示信息，或基站通过第一时频资源的TTI的后N个TTI的控制信道下发指示信息；当占用比大于占用阈值时，基站通过第一时频资源的TTI的后N个TTI的控制信道下发指示信息。
也就是说，第二时频资源被一个或多个其他终端占用，则无论有没有指示信息，对数据解调没有影响。也就是说，当占用比大于占用阈值时，假设为K，即当占用比大于K时，可在第一时频资源的TTI的后N个TTI的控制信道中获取指示信息，而占用比小于K时，可在第二时频资源的TTI的控制信道所在的符号中或第一时频资源的TTI的后N个TTI的控制信道中获取指示信息，从而 提高数据解调的效率和正确率。
在本实施例中，指示信息可在第二时频资源的TTI的控制信道所在的符号中，也可在第一时频资源的TTI的后N个TTI的控制信道中。也就是说，终端在接收基站下发的控制信令和数据时，先要监听控制信道中可能出现的指示信息的位置，当监听到指示信息的位置后，获取指示信息。

当终端的执行业务的业务等级低于等级阈值时，通过第二时频资源的TTI的控制信道所在的符号中下发指示信息，或通过第一时频资源的TTI的后N个TTI的控制信道中下发指示信息；
业务等级的确定因素至少包括终端的执行业务的时延需求。
可选的，第一发送模块204具体用于：

当占用比大于占用阈值时，通过第一时频资源的TTI的后N个TTI的控制信道中下发指示信息。
本发明第五方面提出一种数据处理系统，该系统包括本发明第一方面和第二方面提出的数据处理装置。
具体的，系统执行的时序图如图7所示，包括：
步骤S702：基站将已分配给终端的第一时频资源中的第二时频资源分配给其他终端，根据第二时频资源生成指示信息。
在本实施例中，第二时频资源为基站将已分配给终端的第一时频资源中的部分时频资源分配给其他终端的时频资源。也就是说，基站为了满足多业务复用，将终端的第一时频资源中为其他终端分配的时频资源作为第二时频资源。
在本实施例中，指示信息是根据第二时频资源生成的。根据指示信息终端就可以识别第二时频资源的信息，终端在进行数据解码时只需解码第一时频资 源中除第二时频资源以外的其他资源所传输的数据即可，而不需要解码第二时频资源所传输的数据，从而提高了数据解调的效率和正确率。
步骤S704：基站将指示信息下发给终端。
可选的，指示信息位于第二时频资源的TTI的控制信道所在的符号中，基站将指示信息携带在下行链路控制信息DCI中下发给终端，或指示信息位于第一时频资源的TTI的后N个TTI的控制信道中，基站通过新空口物理下行控制信道NR-PDCCH或组内物理下行控制信道group common PDCCH传输指示信息，N为大于等于1的整数。
可选的，指示信息的位置可通过终端的业务支持能力、终端的执行业务的业务等级和第二时频资源与第一时频资源之间的占用比来确定，此外可能还包括其它确定方式，本发明实施例不作限定。
其中，当终端支持其他终端的业务时，基站通过第二时频资源的TTI的控制信道所在的符号下发指示信息，或基站通过第一时频资源的TTI的后N个TTI的控制信道下发指示信息；当终端不支持其他终端的业务时，基站通过第一时频资源的TTI的后N个TTI的控制信道下发指示信息。
由于终端必然支持终端的业务，当终端支持其他终端的业务时，指示信息通过DCI或复用NR-PDCCH或PDCCH传输给终端，则终端在第二时频资源的TTI的控制信道所在的符号中或第一时频资源的TTI的后N个TTI的控制信道中获取指示信息。而终端不支持其他终端的业务时，指示信息只能复用NR-PDCCH或PDCCH传输给终端，则终端在第一时频资源的TTI的后N个TTI中获取指示信息。
其中，当终端的执行业务的业务等级高于或等于等级阈值时，基站通过第二时频资源的TTI的控制信道所在的符号下发指示信息；当终端的执行业务的业务等级低于等级阈值时，基站通过第二时频资源的TTI的控制信道所在的符号下发指示信息，或基站通过第一时频资源的TTI的后N个TTI的控制信道下发指示信息。
在本实施例中，业务等级的确定因素至少包括终端的执行业务的时延需求。根据终端的执行业务的时延需求确定业务等级，其中，业务时延需求越高业务等级越高。此外还可包括其它确定因素，对于业务等级的确定因素本发明不作限定。
也就是说，当终端的执行业务的业务等级高于或等于等级阈值时，为了提高数据解调的效率和正确率，指示信息通过DCI传输给终端，则终端在第二时频资源的TTI的控制信道所在的符号中获取指示信息。而业务等级低于等级阈值时，指示信息可通过DCI传输给终端，也可通过复用NR-PDCCH或PDCCH传输给终端，则终端在第一时频资源的TTI的后N个TTI的控制信道中获取指示信息。
需要说明的是，本实施例对于终端和其他终端的执行业务不作限定。但优选的是，终端执行eMBB业务，其他终端执行URLLC业务。也就是说，终端的执行业务的业务等级是eMBB业务的业务等级。
其中，确定第二时频资源与第一时频资源之间的占用比；当占用比小于或等于占用阈值时，基站通过第二时频资源的TTI的控制信道所在的符号下发指示信息，或基站通过第一时频资源的TTI的后N个TTI的控制信道下发指示信息；当占用比大于占用阈值时，基站通过第一时频资源的TTI的后N个TTI的控制信道下发指示信息。
也就是说，第二时频资源被一个或多个其他终端占用，则无论有没有指示信息，对数据解调没有影响。也就是说，当占用比大于占用阈值时，假设为K，即当占用比大于K时，可在第一时频资源的TTI的后N个TTI的控制信道中获取指示信息，而占用比小于K时，可在第二时频资源的TTI的控制信道所在的符号中或第一时频资源的TTI的后N个TTI的控制信道中获取指示信息，从而提高数据解调的效率和正确率。
在本实施例中，指示信息可在第二时频资源的TTI的控制信道所在的符号中，也可在第一时频资源的TTI的后N个TTI的控制信道中。也就是说，终端在接收基站下发的控制信令和数据时，先要监听控制信道中可能出现的指示信息的位置，当监听到指示信息的位置后，获取指示信息。
优选的，基站将无线资源控制RRC信令下发给终端，RRC信令用于指示终端从第一时频资源的TTI的后N个TTI的控制信道或第二时频资源的TTI的控制信道所在的符号中获取指示信息。
也就是说，终端根据RRC信令即可获取指示信息的位置信息，从而提高了获取指示信息的效率，并降低终端的功耗。
优选的，指示信息的时域粒度为微时隙级别或符号级别。也就是说，指示信息的时域粒度可为微时隙mini-slot级别，也可以为符号级别。由于微时隙级别的时域粒度大于符号级别的时域粒度，从而进一步提高数据解码的灵活性，并降低功耗。
具体的，当第二时频资源在时域上大于或等于两个符号时，指示信息的时域粒度为微时隙级别；当第二时频资源在时域上为一个符号长度，指示信息的时域粒度为符号级别。
也就是说，当第二时频资源在时域上大于或等于两个符号时，采用微时隙mini-slot级别的时域粒度传输指示信息，而第二时频资源在时域上为一个符号时，采用符号级别的时域粒度传输指示信息。由于微时隙级别的时域粒度大于符号级别的时域粒度，从而进一步提高数据解码的灵活性，并降低功耗。
举例来说，假设TTI中共有7个符号，控制信息占用一个符号。若以符号级别传输指示信息，需要6bit来指示，其中，反馈字符为0表示不用，反馈字 符为1表示使用；而第二时频资源在时域若为2个符号，则以微时隙级别为时域粒度传输指示信息，需要5bit来指示，从而减少信令开销。
步骤S706：终端获取基站下发的指示信息。
在本实施例中，指示信息可在第二时频资源的TTI的控制信道所在的符号中，也可在第一时频资源的TTI的后N个TTI的控制信道中。也就是说，终端在接收基站下发的控制信令和数据时，先要监听控制信道中可能出现的指示信息的位置，当监听到指示信息的位置后，获取指示信息。
优选的，终端获取基站下发的指示信息的步骤之前，还包括：终端接收基站下发的无线资源控制RRC信令，RRC信令用于指示终端从第一时频资源的TTI的后N个TTI的控制信道或第二时频资源的TTI的控制信道所在的符号中获取指示信息。
也就是说，终端根据RRC信令即可获取指示信息的位置信息，从而提高了获取指示信息的效率，并降低终端的功耗。
步骤S708：终端根据指示信息跳过第二时频资源，对第一时频资源中除第二时频资源以外的其他资源所传输的数据进行数据解码。
本实施例对于具体的数据解码过程不作限定。
基站将用于指示第二时频资源的指示信息下发给终端，由于指示信息中包含第二时频资源的信息，则终端在进行数据解码时只需解码第一时频资源中除第二时频资源以外的其他资源所传输的数据即可，而不需要解码第二时频资源所传输的数据，从而提高数据解调的效率和正确率。
实施本发明实施例，将具有如下有益效果：
采用了上述的数据处理方法及装置之后，当终端获取基站下发的指示信息时，根据指示信息跳过第二时频资源，对第一时频资源中除第二时频资源以外的其他资源所传输的数据进行数据解码。其中，第二时频资源为基站将已分配给终端的第一时频资源中的部分时频资源分配给其他终端的时频资源。也就是说，终端只解码针对终端的数据，而不需解码其他终端的数据，从而提高了数据解调的效率和正确率。
