Technical field

本发明涉及通信技术领域，特别涉及一种调度方法、装置和设备。The present invention relates to the field of communications technologies, and in particular, to a scheduling method, apparatus, and device.

Background technique

为了减少控制信令的开销，长期演进(Long Term Evolution，简称LTE)系统中，针对数据包大小基本相同且到达时间间隔比较有规律的业务，引入了半持续调度(Semi-Persistent Scheduling，简称SPS)，并且规定一个用户设备(User Equipment，简称UE)只能配置一套SPS资源。SPS的周期和使用的SPS小区级无线网络临时标识(Cell-Radio Network Temporary Identifier，简称C-RNTI)由无线资源控制(Radio Resource Control，简称RRC)配置。SPS资源由基站通过调度信令通知给UE，调度信令通过物理下行控制信道(Physical Downlink Control Channel，简称PDCCH)传输。PDCCH具有多种下行控制信息(Downlink Control Information，简称DCI)格式(format)，其中，DCI format0用于上行，其余的格式(如DCI format1/1A/2/2A等)均用于下行。用于激活/释放SPS资源的PDCCH DCI格式中某些域需要取特殊值。In order to reduce the overhead of control signaling, in the Long Term Evolution (LTE) system, Semi-Persistent Scheduling (SPS) is introduced for services with the same packet size and regular arrival time interval. ), and a user equipment (User Equipment, UE for short) can be configured to configure only one set of SPS resources. The SPS cell and the used Cell-Radio Network Temporary Identifier (C-RNTI) are configured by Radio Resource Control (RRC). The SPS resource is notified to the UE by the base station through scheduling signaling, and the scheduling signaling is transmitted through a Physical Downlink Control Channel (PDCCH). The PDCCH has a plurality of downlink control information (DCI) format, in which DCI format0 is used for uplink, and other formats (such as DCI format 1/1A/2/2A, etc.) are used for downlink. Certain fields in the PDCCH DCI format used to activate/release SPS resources require special values.

对于UE而言，利用基站配置的SPS机会(SPS occasion)进行SPS传输。具体的上/下行SPS occasion确定方式如下：For the UE, the SPS transmission is performed using the SPS occasion configured by the base station. The specific up/down SPS occasions are determined as follows:

对于下行，SPS occasion的位置在满足如下条件的子帧(subframe)上：For the downlink, the location of the SPS occasion is on a subframe that satisfies the following conditions:

(10*SFN+subframe)＝[(10*SFNstart time+subframestart time)+N*semiPersistSchedIntervalDL]modulo 10240；(10*SFN+subframe)=[(10*SFNstart time+subframestart time)+N*semiPersistSchedIntervalDL]modulo 10240;

对于上行，SPS occasion位置在满足如下条件的subframe上： For the uplink, the SPS occasion is placed on a subframe that satisfies the following conditions:

(10*SFN+subframe)＝[(10*SFNstart time+subframestart time)+N*semiPersistSchedIntervalUL+Subframe_Offset*(N modulo 2)]modulo 10240。(10*SFN+subframe)=[(10*SFNstart time+subframestart time)+N*semiPersistSchedIntervalUL+Subframe_Offset*(N modulo 2)]modulo 10240.

其中，SFNstart time和subframestart time分别表示下行SPS激活的无线帧和子帧编号；semiPersistSchedIntervalDL表示RRC信令配置的下行SPS周期；semiPersistSchedIntervalUL表示RRC信令配置的上行SPS周期；Subframe_Offset根据RRC信令是否配置了twoIntervalsConfig而取不同值。The SFNstart time and the subframestart time respectively indicate the radio frame and the subframe number of the downlink SPS activation; the semiPersistSchedIntervalDL indicates the downlink SPS period of the RRC signaling configuration; the semiPersistSchedIntervalUL indicates the uplink SPS period of the RRC signaling configuration; and the Subframe_Offset configures the twoIntervalsConfig according to the RRC signaling. And take different values.

V2X通信是目前通信领域一个热门议题，在2015年在3GPP RAN#67次会议上正式立项。V2X通信主要包含三方面内容：V2X communication is a hot topic in the field of communication, and was officially established at the 3GPP RAN#67 meeting in 2015. V2X communication mainly includes three aspects:

V2V(Vechile-to-Vechile，车到车)：车上的车载单元(On Broad Unit，简称OBU)之间的通信；V2V (Vechile-to-Vechile, car to car): communication between the On Broad Unit (OBU) on the vehicle;

V2I(Vechile-to-Infrastructure，车道网络)：车和路侧设备(Road Side Unit，简称RSU)之间的通信；V2I (Vechile-to-Infrastructure): communication between the vehicle and the Road Side Unit (RSU);

V2P(Vechile-to-Pedestrian，车到行人)：车和行人之间的通信。V2P (Vechile-to-Pedestrian, car to pedestrian): communication between the car and the pedestrian.

上述三种V2X通信方式中，V2V对时延要求最高。具体时延要求是端到端的时延不能超过100ms。对于V2X，具体有两种传输机制：PC5V2X和Uu V2X。所谓PC5V2X即车和通信对端之间使用直接通信接口进行通信；所谓Uu V2X即车和通信对端之间使用传统的LTE网络进行通信。Among the above three V2X communication methods, V2V has the highest latency requirement. The specific delay requirement is that the end-to-end delay cannot exceed 100ms. For V2X, there are two transmission mechanisms: PC5V2X and Uu V2X. The so-called PC5V2X car and the communication peer use the direct communication interface for communication; the so-called Uu V2X car and the communication peer use the traditional LTE network for communication.

针对Uu V2X为了减少调度请求(Scheduling Request，简称SR)/缓冲区状态上报(Buffer Status Reporting，简称BSR)的开销，建议上行使用SPS。但是由于V2X业务到达时刻和SPS资源不一定匹配，例如，V2X业务本身不是周期的，由于SPS资源是周期分配的，使得V2X业务到达时刻和SPS资源无法匹配，在使用SPS资源传输V2X业务时，会增大业务时延。For the Uu V2X to reduce the overhead of the Scheduling Request (SR)/Buffer Status Reporting (BSR), it is recommended to use SPS upstream. However, since the V2X service arrival time does not necessarily match the SPS resource, for example, the V2X service itself is not periodic. Since the SPS resource is periodically allocated, the V2X service arrival time and the SPS resource cannot be matched. When the SP2 resource is used to transmit the V2X service, Will increase business latency.

具体的，若传输方向为上行，则S11中根据配置的上行SPS occasion和上行SPS窗口长度，确定出上行SPS窗口，其中，上行SPS窗口以所配置的上行SPS occasion为结束时刻；Specifically, if the transmission direction is uplink, the uplink SPS window is determined according to the configured uplink SPS occasion and the length of the uplink SPS window, where the uplink SPS window is the end time of the configured uplink SPS occasion;

若传输方向为下行，则S11中根据配置的下行SPS occasion和下行SPS窗口长度，确定出下行SPS窗口，其中，下行SPS窗口以所配置的下行SPS occasion为结束时刻。If the transmission direction is downlink, the downlink SPS window is determined according to the configured downlink SPS occasion and the downlink SPS window length, where the downlink SPS window is the ending time of the configured downlink SPS occasion.

本发明实施例中，传输方向上配置的SPS窗口长度可以相同，也可以不同，本发明不对其进行限定。In the embodiment of the present invention, the SPS window lengths configured in the transmission direction may be the same or different, and the present invention does not limit them.

S12、在判断出所述传输方向上的数据的到达时刻位于所述传输方向对应的SPS窗口内时，采用SPS方式传输所述数据；S12. When it is determined that the arrival time of the data in the transmission direction is located in the SPS window corresponding to the transmission direction, the data is transmitted by using an SPS method.

若所述传输方向上的数据的到达时刻位于所述传输方向对应的SPS窗口内，则可认为所配置的SPS资源能够与所述传输方向上的数据匹配，此时，采用SPS方式传输数据，能够在保证业务时延的前提下，降低信令开销。If the arrival time of the data in the transmission direction is located in the SPS window corresponding to the transmission direction, it may be considered that the configured SPS resource can match the data in the transmission direction, and at this time, the data is transmitted by using the SPS method. The signaling overhead can be reduced while ensuring service delay.

在实施中，一种可能的实现方式是，若传输方向为上行，则S12中在判断出上行数据的到达时刻位于上行SPS窗口内时，采用SPS方式传输上行数据。进一步，若为基站侧，则采用所配置的SPS资源接收上行数据；若为终端侧，则采用基站配置的SPS资源发送上行数据。In an implementation, in a possible implementation manner, if the transmission direction is uplink, the uplink data is transmitted by using the SPS mode when it is determined that the arrival time of the uplink data is located in the uplink SPS window.

实施中，若所述传输方向上的数据的到达时刻位于所述传输方向对应的SPS窗口外，则可认为所配置的SPS资源不能够与所述传输方向上的数据匹配，此时，若仍采用SPS方式传输数据，则会增大业务时延，因此，可采用动态调度方式传输数据，以保证业务时延。In an implementation, if the arrival time of the data in the transmission direction is outside the SPS window corresponding to the transmission direction, it may be considered that the configured SPS resource cannot match the data in the transmission direction. When data is transmitted in the SPS mode, the service delay is increased. Therefore, dynamic scheduling can be used to transmit data to ensure service delay.

Further, if it is the base station side, the uplink data is received by the dynamically configured resource; if it is the terminal side, the uplink data is transmitted by the resource dynamically configured by the base station.

另一种可能的实现方式是，若传输方向为下行，则S13中在判断出下行数据的到达时刻位于下行SPS窗口外时，采用动态调度方式传输下行数据。进一步，若为基站侧，则采用动态配置的资源发送下行数据；若为终端侧，则采用基站动态配置的资源接收下行数据。Another possible implementation manner is: if the transmission direction is downlink, the downlink data is transmitted in a dynamic scheduling manner when it is determined that the arrival time of the downlink data is outside the downlink SPS window in S13. Further, if it is the base station side, the downlink data is transmitted by using the dynamically configured resource; if it is the terminal side, the downlink data is received by the resource dynamically configured by the base station.

本发明实施例中，所述传输方向上配置的SPS窗口对应的时域位置为[M-N，M]，其中，M表示所述传输方向上配置的SPS occasion所在的时域位置，N表示所述传输方向上配置的SPS窗口长度。In the embodiment of the present invention, the time domain location corresponding to the SPS window configured in the transmission direction is [MN, M], where M represents a time domain location where the SPS occasion configured in the transmission direction is located, and N represents the The length of the SPS window configured in the transport direction.

另一种可能的实现方式是，若所述传输方向为下行，所述传输方向上的数据的到达时刻为：基站侧的MAC层接收到基站侧的高层下发的下行数据包的时刻。In another possible implementation manner, if the transmission direction is downlink, the time of arrival of the data in the transmission direction is: a time when the MAC layer of the base station side receives the downlink data packet sent by the upper layer of the base station side.

The delay requirements are determined. The delay requirement of the uplink service can be obtained from the quality of service (QoS) of the uplink service, and the delay requirement of the downlink service can be obtained from the QoS of the downlink service.
