Description
本申请要求在2017年6月16日提交中国专利局、申请号为201710459138.1、发明名称为“一种调度信息传输方法及装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。The present application claims the priority of the Chinese Patent Application, which is filed on June 16, 2017, the Chinese Patent Application No. PCT Application No. in.
本申请涉及无线通信技术领域,尤其涉及一种调度信息传输方法及装置。The present application relates to the field of wireless communications technologies, and in particular, to a scheduling information transmission method and apparatus.
智能终端用户的不断增长、用户业务量和数据吞吐量不断增加,对通信带宽和速率提出了更高的要求。为此,引入了载波聚合(Carrier Aggregation,CA)技术。通过载波聚合可以将多个连续或不连续的成员载波聚合起来使用,此外第五代移动通信下一代无线电技术(the 5th Generation mobile communication technology New Radio,5G NR)系统还定义了其他频率资源,比如部分带宽(Bandwidth Part,BP),解决了移动通信对于大带宽的需求,并提高了无线频带中零散频谱的利用率。长期演进(Long Term Evolution,LTE)系统的载波聚合技术支持跨载波调度。跨载波调度是指在一个成员载波上调度另外的成员载波的数据信道资源。The growing number of intelligent terminal users, the increasing volume of user traffic and data throughput have placed higher demands on communication bandwidth and speed. To this end, Carrier Aggregation (CA) technology has been introduced. A plurality of consecutive or discontinuous component carriers can be aggregated by carrier aggregation, and the 5th Generation mobile communication technology New Radio (5G NR) system also defines other frequency resources, such as Part bandwidth (Bandwidth Part, BP) solves the demand for large bandwidth of mobile communication and improves the utilization of scattered spectrum in the wireless frequency band. The carrier aggregation technology of the Long Term Evolution (LTE) system supports cross-carrier scheduling. Cross-carrier scheduling refers to scheduling data channel resources of additional component carriers on one component carrier.
5G系统需要支持更多的业务和更丰富的频谱资源,因此载波聚合以及跨载波调度技术会继续采用,并且由于BP的引入,跨BP的调度和反馈也会支持。但在LTE系统中,子载波间隔是固定的。在5G系统中,考虑到高频段的无线传播特性与低频段的无线传输特性差别较大,因此不同频段上子载波间隔可能不同。比如,低频段上子载波间隔为15khz,高频段上子载波间隔为60khz。即使同一频段内,不同载波上的子载波间隔也可能不同。The 5G system needs to support more services and richer spectrum resources, so carrier aggregation and cross-carrier scheduling technology will continue to be adopted, and due to the introduction of BP, cross-BP scheduling and feedback will also be supported. However, in the LTE system, the subcarrier spacing is fixed. In the 5G system, considering that the wireless transmission characteristics of the high frequency band and the wireless transmission characteristics of the low frequency band are largely different, the subcarrier spacing may be different in different frequency bands. For example, the subcarrier spacing on the low frequency band is 15 khz, and the subcarrier spacing on the high frequency band is 60 khz. Even within the same frequency band, the subcarrier spacing on different carriers may be different.
由于5G系统中,子载波间隔不再固定不变,因此使得跨载波或跨BP调度场景较多,复杂度较高。Because the sub-carrier spacing is no longer fixed in the 5G system, the cross-carrier or cross-BP scheduling scenarios are more and the complexity is higher.
发明内容Summary of the invention
本申请实施例提供了一种调度信息传输方法及装置,以期降低频率调度的复杂度。The embodiment of the present application provides a scheduling information transmission method and apparatus, so as to reduce the complexity of frequency scheduling.
第一方面,提供一种调度信息传输方法,包括:In a first aspect, a scheduling information transmission method is provided, including:

The scheduling information is located on the physical downlink control channel, and is used to indicate a data channel resource of the scheduled frequency resource on the scheduling frequency resource, where the scheduling information is an information domain in the downlink control information DCI or DCI, where the scheduling information is The quantity is less than or equal to the maximum number of scheduling information, and the maximum number of scheduling information is determined according to the subcarrier spacing of the scheduled frequency resource and the subcarrier spacing of the scheduling frequency resource, or the length of the time domain unit according to the scheduled frequency resource. And determining the time domain unit length of the scheduling frequency resource, or determining according to the subcarrier spacing of the scheduled frequency resource, the subcarrier spacing of the scheduling frequency resource, and the first preset value, or the time unit according to the scheduled frequency resource. The length of the time unit of the length and the scheduling frequency resource and the first preset value are determined, and the first preset value is used to determine the maximum number of time domain units that the scheduling information can schedule.
由于上述方案中,针对调度信息数量的最大值的计算给出了确定依据,并且网络设备发送的调度信息的数量小于或等于该调度信息数量的最大值,因此对网络设备发送的调度信息的数量进行了限制,可以简化协议标准化和实现的复杂度。该方案可应用于跨频率资源调度,并进一步可应用于跨频率资源调度场景下调度频率资源与被调度频率资源的子载 波间隔不同的情况,即本申请实施例针对跨频率资源调度场景下调度频率资源和被调度频率资源的子载波间隔不同的情况,可以简化协议标准化和实现的复杂度。In the above solution, the determination of the maximum value of the number of scheduling information is given, and the number of scheduling information sent by the network device is less than or equal to the maximum number of the scheduling information, and therefore the number of scheduling information sent to the network device. Limitations have been made to simplify the standardization and complexity of the implementation. The solution is applicable to the cross-frequency resource scheduling, and is further applicable to the case where the scheduling frequency resource and the sub-carrier spacing of the scheduled frequency resource are different in the cross-frequency resource scheduling scenario, that is, the scheduling in the cross-frequency resource scheduling scenario in this embodiment of the present application The case where the frequency resource and the subcarrier spacing of the scheduled frequency resource are different can simplify the standardization of the protocol and the complexity of the implementation.
在一个可能的设计中,所述调度信息用于指示一个或多个时域单元中的被调度频率资源的数据信道资源,所述一个或多个时域单元的数量小于或等于所述第一预设值所指示的所述调度信息可以调度的最大时域单元的数量。这样使得网络设备发送的调度信息所调度的时域单元数量不会超过终端可以调度的最大时域单元的数量,从而可以保证终端的数据传输。In one possible design, the scheduling information is used to indicate data channel resources of scheduled frequency resources in one or more time domain units, the number of the one or more time domain units being less than or equal to the first The number of maximum time domain units that can be scheduled by the scheduling information indicated by the preset value. In this way, the number of time domain units scheduled by the scheduling information sent by the network device does not exceed the maximum number of time domain units that the terminal can schedule, so that the data transmission of the terminal can be guaranteed.
在一个可能的设计中,所述调度信息用于指示一个或多个时域单元中的被调度频率资源的数据信道资源;所述调度信息指示多个时域单元中的被调度频率资源的数据信道资源时,所述多个时域单元中,每个时域单元中的被调度频率资源独立承载传输块,或者全部或者部分时域单元中的被调度频率资源联合承载传输块。In one possible design, the scheduling information is used to indicate data channel resources of scheduled frequency resources in one or more time domain units; the scheduling information indicates data of scheduled frequency resources in multiple time domain units In the case of the channel resource, the scheduled frequency resource in each time domain unit independently carries the transport block, or the scheduled frequency resource in all or part of the time domain unit jointly bears the transport block.
通过该方案,使得网络设备在调度多个时域单元(比如子帧或时隙)的传输时,该多个时域单元中的每个时域单元可以分别与一个传输块对应,或者该多个时域单元中的至少2个时域单元与一个传输块对应,可以提高了调度的灵活性,对现有协议进行了扩展。With this scheme, when the network device schedules transmission of multiple time domain units (such as a subframe or a time slot), each of the multiple time domain units may correspond to one transport block, or more At least two time domain units in the time domain unit correspond to one transport block, which can improve scheduling flexibility and extend the existing protocol.

通过该方案,网络设备可以将其发送的DCI的数量指示给终端,这样终端可根据网络设备所指示的DCI的数量进行DCI的接收,比如当终端接收到的DCI的数量与网络设备所指示的DCI数量相等时,即可停止接收DCI(比如停止在PDCCH搜索空间搜索DCI),从而可以节省终端的处理开销,进而可以节省终端的电源消耗。网络设备也可以将其发送的DCI的数量是一个还是多个指示给终端,这样终端可根据该指示进行DCI的接收。比如当终端根据该指示确定网络设备只发送了一个DCI时,该终端在PDCCH搜索空间搜到发送给该终端的DCI后即可停止搜索,从而可以节省终端的处理开销,进而可以节省终端的电源消耗。With this solution, the network device can indicate the number of DCIs it sends to the terminal, so that the terminal can receive the DCI according to the number of DCIs indicated by the network device, for example, when the number of DCIs received by the terminal is indicated by the network device. When the number of DCIs is equal, the DCI can be stopped (for example, the DCI is stopped in the PDCCH search space), thereby saving the processing overhead of the terminal, thereby saving power consumption of the terminal. The network device can also indicate whether the number of DCIs sent by the terminal is one or more to the terminal, so that the terminal can receive the DCI according to the indication. For example, when the terminal determines, according to the indication, that the network device only sends one DCI, the terminal can stop searching after searching for the DCI sent to the terminal in the PDCCH search space, thereby saving processing overhead of the terminal, thereby saving power of the terminal. Consumption.

通过该方案,在使用一个DCI进行频率资源调度时,网络设备可通过该DCI中的第一指示信息指示被调度频率资源是在该时域单元上独立承载传输块,还是与其他时域单元中的被调度频率资源联合承载传输块,从而可以使终端根据该指示进行数据传输。With the scheme, when the frequency resource scheduling is performed by using one DCI, the network device may indicate, by using the first indication information in the DCI, whether the scheduled frequency resource is independently carrying the transport block on the time domain unit, or is in other time domain units.

其中,本申请实施例对频率资源种类不作限制,比如,上述频率资源可以是载波,也可以是部分带宽(Bandwidth Part,BP)。以频率资源为载波作为例子,上述调度频率资源为调度载波,上述被调度频率资源为被调度载波。以下实施例以调度载波和被调度载波为 例进行描述,应理解,本申请实施例的原理可适用于其他资源调度粒度的情况。The frequency resource of the embodiment of the present application is not limited. For example, the frequency resource may be a carrier or a part bandwidth (BP). Taking the frequency resource as a carrier as an example, the scheduling frequency resource is a scheduling carrier, and the scheduled frequency resource is a scheduled carrier. The following embodiments are described by taking the scheduling carrier and the scheduled carrier as an example. It should be understood that the principles of the embodiments of the present application can be applied to other resource scheduling granularities.
其中,所述物理下行控制信道可以是PDCCH(Physical Downlink Control Channel),所述数据信道可以包括物理下行共享信道(Physical Downlink Shared Channe,PDSCH)和/或物理上行共享信道(Physical Uplink Shared Channel,PUSCH)。The physical downlink control channel may be a PDCCH (Physical Downlink Control Channel), and the data channel may include a Physical Downlink Shared Channe (PDSCH) and/or a Physical Uplink Shared Channel (PUSCH). ).
所述调度信息可以是下行控制信息(Downlink Control Information,DCI)或DCI中的信息域,所述信息域用来指示被调度载波的数据信道资源。DCI中用来指示被调度载波的数据资源的信息域可以是一个或多个(具体数量由网络设备确定),其中,一个信息域可以调度一个或多个混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)进程,一个HARQ进程与一个时域单元对应。DCI是网络设备发送给终端的下行控制信息,其中可包括上下行资源分配、HARQ信息、功率控制等,可承载在PDCCH上发送。其中,一个时域单元可以是一个子帧(subframe),或一个时隙(slot),或一个微时隙(mini-slot)等。The scheduling information may be Downlink Control Information (DCI) or an information field in the DCI, where the information field is used to indicate a data channel resource of the scheduled carrier. The information field used in the DCI to indicate the data resources of the scheduled carrier may be one or more (the specific number is determined by the network device), wherein one information domain may schedule one or more hybrid automatic repeat requests (Hybrid Automatic Repeat reQuest) , HARQ process, a HARQ process corresponds to a time domain unit. The DCI is downlink control information that is sent by the network device to the terminal, and may include uplink and downlink resource allocation, HARQ information, power control, etc., and may be carried on the PDCCH. One time domain unit may be a subframe, or a slot, or a mini-slot.
在一个例子中,CC1表示调度载波、CC2表示被调度载波,网络设备通过CC1的PDCCH向终端发送DCI,该DCI中包括CC2上的PDSCH资源指示信息,通过该指示信息指示分配给该终端使用的CC2上的PDCCH时频资源位置,以使该终端可在所指示的CC2上的PDCCH上接收网络设备发送的数据。在另外的例子中,CC1表示调度载波、CC2表示被调度载波,网络设备通过CC1的PDCCH向终端发送DCI,该DCI中包括CC2上的PUSCH资源指示信息,通过该指示信息指示分配给该终端使用的CC2上的PUSCH时频资源位置,以使该终端可在所指示的CC2上的PUSCH上向网络设备发送数据。In an example, the CC1 indicates the scheduling carrier, and the CC2 indicates the scheduled carrier. The network device sends the DCI to the terminal through the PDCCH of the CC1. The DCI includes the PDSCH resource indication information on the CC2, and the indication information is used to indicate the allocation to the terminal. The PDCCH time-frequency resource location on CC2 is such that the terminal can receive data transmitted by the network device on the indicated PDCCH on CC2. In another example, the CC1 indicates the scheduling carrier, and the CC2 indicates the scheduled carrier. The network device sends the DCI to the terminal through the PDCCH of the CC1. The DCI includes the PUSCH resource indication information on the CC2, and the indication information is used to indicate the allocation to the terminal. The PUSCH time-frequency resource location on CC2 is such that the terminal can transmit data to the network device on the indicated PUSCH on CC2.
上述调度载波和被调度载波可以是相同的载波,也可以是不同的载波。比如如图2所示,图2中的(a)示出了未采用跨载波调度(即调度载波和被调度载波为相同载波)的示意图,图2中的(b)示出了跨载波调度(即调度载波和被调度载波为不同载波)的示意图,可以看出,在跨载波调度时,一个载波上的PDCCH可指示其他载波上的PDSCH资源。在调度载波和被调度载波为不同的载波的情况下,本申请实施例针对跨载波调度的场景,给出了调度信息传输方法以实现跨载波调度。The above scheduling carrier and the scheduled carrier may be the same carrier or different carriers. For example, as shown in FIG. 2, (a) in FIG. 2 shows a schematic diagram in which cross-carrier scheduling is not adopted (that is, the scheduling carrier and the scheduled carrier are the same carrier), and (b) in FIG. 2 shows cross-carrier scheduling. (A schematic diagram of the scheduling carrier and the scheduled carrier being different carriers), it can be seen that, during cross-carrier scheduling, the PDCCH on one carrier can indicate the PDSCH resources on other carriers. In the case that the scheduling carrier and the scheduled carrier are different carriers, the embodiment of the present application provides a scheduling information transmission method to implement cross-carrier scheduling for the scenario of cross-carrier scheduling.
在图3所示的跨载波调度的例子中,一个宏基站小区(对应于图中的macro cell)和一个小基站小区(对应于图中的small cell)共享2个下行承载载波:CC1和CC2。small cell的2个成员载波都在低传输功率下工作,macro cell的CC1在高传输功率工作,CC2在低传输功率工作。macro cell在CC1上的传输对small cell的CC1存在干扰。因此,在small cell上,使用CC2上的PDCCH来跨载波调度在CC1上的PDSCH资源;在macro cell上,使用CC1上的PDCCH来跨载波调度在CC2上的PDSCH资源。In the example of cross-carrier scheduling shown in FIG. 3, one macro base station cell (corresponding to the macro cell in the figure) and one small base station cell (corresponding to the small cell in the figure) share two downlink bearer carriers: CC1 and CC2. . The two component carriers of the small cell operate at low transmission power, the CC1 of the macro cell operates at high transmission power, and the CC2 operates at low transmission power. The transmission of the macro cell on CC1 interferes with CC1 of the small cell. Therefore, on the small cell, the PDCCH on CC2 is used to schedule PDSCH resources on CC1 across carriers; on the macro cell, the PDCCH on CC1 is used to schedule PDSCH resources on CC2 across carriers.
进一步地,在跨载波调度的场景下,调度载波的子载波间隔与被调度载波的子载波间隔,可以相同也可以不同。在调度载波的子载波间隔与被调度载波的子载波间隔不相同的一个例子中,如图4A所示,调度载波(图中示为CC1)位于高频段,子载波间隔为15KHz,被调度载波(图中示为CC2)位于低频段,子载波间隔为60KHz,网络设备通过CC1上的PDCCH发送调度信息以指示CC2上的PDSCH和/或PUSCH的资源(比如PDSCH和/或PUSCH所在的时隙以及所在的频域位置)。在另外的例子中,如图4B所示,调度载波(图中示为CC1)位于高频段,子载波间隔为15KHz,被调度载波(图中示为CC2)位于低频段,子载波间隔为30KHz,网络设备通过CC1上的PDCCH发送调度信息以指示CC2上的PDSCH和/或PUSCH的资源(比如PDSCH和/或PUSCH所在的时隙以及所在的频域位置)。Further, in a scenario of cross-carrier scheduling, the subcarrier spacing of the scheduling carrier and the subcarrier spacing of the scheduled carrier may be the same or different. In an example where the subcarrier spacing of the scheduling carrier is different from the subcarrier spacing of the scheduled carrier, as shown in FIG. 4A, the scheduling carrier (shown as CC1 in the figure) is located in the high frequency band, and the subcarrier spacing is 15 kHz, and the scheduled carrier is (CC2 shown in the figure) is located in the low frequency band, and the subcarrier spacing is 60 kHz. The network device sends scheduling information through the PDCCH on CC1 to indicate the resources of the PDSCH and/or the PUSCH on the CC2 (such as the time slot where the PDSCH and/or the PUSCH are located). And the location of the frequency domain). In another example, as shown in FIG. 4B, the scheduling carrier (shown as CC1 in the figure) is located in the high frequency band, the subcarrier spacing is 15 kHz, and the scheduled carrier (shown as CC2 in the figure) is located in the low frequency band, and the subcarrier spacing is 30 kHz. The network device sends scheduling information through the PDCCH on the CC1 to indicate the resources of the PDSCH and/or the PUSCH on the CC2 (such as the time slot in which the PDSCH and/or the PUSCH are located and the frequency domain location in which the PUSCH is located).
本申请实施例中,网络设备确定出的调度信息的数量小于或等于调度信息数量的最大值,该调度信息数量的最大值可根据被调度载波的子载波间隔和调度载波的子载波间隔确定的,或者,根据被调度载波的子载波间隔、调度载波的子载波间隔、第一预设值确定的。可以看出,由于本申请实施例中针对调度信息数量的最大值的计算给出了计算依据,并且网络设备发送的调度信息的数量小于或等于该调度信息数量的最大值,因此对网络设备发送的调度信息的数量进行了限制,尤其针对跨载波调度场景下调度载波和被调度载波的子载波间隔不同的情况,可以简化协议标准化和实现的复杂度。In this embodiment, the number of scheduling information determined by the network device is less than or equal to the maximum number of scheduling information, and the maximum value of the scheduling information may be determined according to a subcarrier spacing of the scheduled carrier and a subcarrier spacing of the scheduling carrier. Or, according to the subcarrier spacing of the scheduled carrier, the subcarrier spacing of the scheduling carrier, and the first preset value. It can be seen that, because the calculation of the maximum value of the number of scheduling information is given in the embodiment of the present application, and the number of scheduling information sent by the network device is less than or equal to the maximum value of the scheduling information, the network device is sent. The number of scheduling information is limited, especially for the case where the subcarrier spacing of the scheduling carrier and the scheduled carrier is different in the cross-carrier scheduling scenario, which can simplify the standardization of the protocol and the complexity of implementation.
其中,所述第一预设值用于指示调度信息可以调度的最大时域单元的数量,该第一预设值可以表征终端的联合调度能力。对于子载波间隔不同的被调度载波,终端的该第一预设值可能不同。所述时域单元可以是子帧也可以是时隙,相应地,所述第一预设值用于指示调度信息可以调度的最大子帧数量,比如,被调度载波CC2的子载波间隔为15Khz的情况下,终端的第一预设值等于1,表示在调度载波CC1上最多可为该终端调度1个子帧内在被调度载波CC2上的数据信道资源。所述第一预设值也可用于指示调度信息可以调度的最大时隙数量,比如,被调度载波CC2的子载波间隔为15Khz的情况下,终端的第一预设值等于2,表示在调度载波CC1上最多可为该终端调度2个时隙内在被调度载波CC2上的数据信道资源。终端的第一预设值由系统约定或由终端上报给网络设备。The first preset value is used to indicate the maximum number of time domain units that the scheduling information can schedule, and the first preset value can be used to represent the joint scheduling capability of the terminal. The first preset value of the terminal may be different for the scheduled carriers with different subcarrier spacings. The time domain unit may be a subframe or a time slot. Correspondingly, the first preset value is used to indicate the maximum number of subframes that the scheduling information can be scheduled. For example, the subcarrier spacing of the scheduled carrier CC2 is 15Khz. The first preset value of the terminal is equal to 1, indicating that the data channel resource on the scheduled carrier CC2 within one subframe can be scheduled for the terminal on the scheduling carrier CC1. The first preset value may also be used to indicate the maximum number of time slots that the scheduling information can be scheduled. For example, if the subcarrier spacing of the scheduled carrier CC2 is 15 Khz, the first preset value of the terminal is equal to 2, indicating that the scheduling is in the scheduling. On the carrier CC1, the data channel resources on the scheduled carrier CC2 in the two slots can be scheduled for the terminal at most. The first preset value of the terminal is reported by the system or reported by the terminal to the network device.
在另外的实施例中,不同的载波上的时域单元长度有可能不同。比如,15KHz载波对应的频率资源上的一个时域单元(本例中以一个时域单元为一个时隙为例描述)包含7个正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)符号,该时隙的长度为0.5ms;在60HKz载波对应的频率资源上的一个时域单元(本例中以一个时域单元为一个时隙为例描述)包含14个OFDM符号,该时隙的长度为0.25ms。此种情况下,如果调度载波和被调度载波的时域单元长度不同,则所述调度信息数量的最大值可根据被调度载波的时域单元长度和调度载波的时域单元长度来确定,或者根据被调度载波的时域单元长度和调度载波的时域单元长度以及上述第一预设值来确定。其中,一个时域单元可以是一个子帧(subframe),或一个时隙(slot),或一个微时隙(mini-slot)等。In other embodiments, the length of the time domain unit on different carriers may be different. For example, a time domain unit on a frequency resource corresponding to a 15 kHz carrier (in this example, a time domain unit is a time slot as an example) includes seven Orthogonal Frequency Division Multiplexing (OFDM) symbols. The length of the time slot is 0.5 ms; a time domain unit on the frequency resource corresponding to the 60HKz carrier (in this example, one time domain unit is a time slot as an example) includes 14 OFDM symbols, and the length of the time slot. It is 0.25ms. In this case, if the time domain unit lengths of the scheduling carrier and the scheduled carrier are different, the maximum value of the scheduling information may be determined according to the time domain unit length of the scheduled carrier and the time domain unit length of the scheduling carrier, or And determining according to the length of the time domain unit of the scheduled carrier and the length of the time domain unit of the scheduling carrier and the first preset value. One time domain unit may be a subframe, or a slot, or a mini-slot.
本申请实施例中,在确定调度信息数量的最大值时,可根据调度载波的子载波间隔和被调度载波的子载波间隔之间的大小关系(比如,该大小关系可以用以下比值来表示:被调度载波的子载波间隔除以调度载波的子载波间隔)来确定。在另外的例子中,不同载波上的时域单元长度可能不同,在确定调度信息数量的最大值时,可根据调度载波和被调度载波的时域单元长度的大小关系(比如,该大小关系用以下比值来表示:调度载波的时隙长度除以被调度载波的时隙长度,或者被调度载波的时隙长度除以调度载波的时域长度)来确定。In the embodiment of the present application, when determining the maximum value of the scheduling information, the size relationship between the subcarrier spacing of the scheduling carrier and the subcarrier spacing of the scheduled carrier may be used. For example, the size relationship may be represented by the following ratio: The subcarrier spacing of the scheduled carrier is divided by the subcarrier spacing of the scheduling carrier). In another example, the length of the time domain unit on different carriers may be different. When determining the maximum number of scheduling information, the size relationship between the scheduling carrier and the time domain unit length of the scheduled carrier may be used (for example, the size relationship is used). The following ratio is used to indicate that the slot length of the scheduling carrier is divided by the slot length of the scheduled carrier, or the slot length of the scheduled carrier is divided by the time domain length of the scheduling carrier.
基于上述确定调度信息数量的最大值的原则,下面示例性地示出了本申请实施例提供的几种确定上述调度信息数量的最大值的方法。Based on the above-mentioned principle of determining the maximum value of the number of scheduling information, the following describes exemplarily several methods for determining the maximum value of the above-mentioned scheduling information provided by the embodiments of the present application.
方法1:确定第一比值,所述第一比值等于被调度频率资源的子载波间隔除以调度频率资源的子载波间隔所得到的比值再除以所述第一预设值,或者所述第一比值等于被调度频率资源的时域单元长度除以调度频率资源的时域单元长度所得到的比值再除以所述第一预设值后所得到的近似整数。若该第一比值大于1且小于第一设定值,则调度信息数量的最大值等于该第一比值,若该第一比值大于1且大于等于第一设定值,则调度信息数量的最大值等于该第一设定值,若该第一比值小于等于1,则调度信息数量的最大值等于 1。其中,所述第一设定值表示在调度载波上允许发送的调度信息数量的最大值,可由协议规定或系统配置。Method 1: Determine a first ratio, the first ratio being equal to a ratio of a subcarrier spacing of the scheduled frequency resource divided by a subcarrier spacing of the scheduling frequency resource, and dividing by the first preset value, or the first An approximate integer obtained by dividing the ratio of the time domain unit length of the scheduled frequency resource by the time domain unit length of the scheduling frequency resource and dividing by the first preset value. If the first ratio is greater than 1 and less than the first set value, the maximum number of scheduling information is equal to the first ratio, and if the first ratio is greater than 1 and greater than or equal to the first set value, the maximum number of scheduling information The value is equal to the first set value. If the first ratio is less than or equal to 1, the maximum number of scheduling information is equal to 1. The first set value represents a maximum value of the number of scheduling information allowed to be transmitted on the scheduling carrier, which may be specified by a protocol or configured by a system.
上述方法1可表示为以下公式(1):The above method 1 can be expressed as the following formula (1):
K=min(b,max(1,M/N))……………………………………(1)K=min(b,max(1,M/N))....................................(1)
公式(1)中,b表示:对于被调度载波,调度载波上针对其上所有终端或部分终端(包括某特定终端)的调度信息数量的最大值,b为大于或等于1的整数。b的取值可由协议规定或系统配置,比如可由系统信息块(System Information Block,SIB)或者由无线资源控制(Radio Resource Control,RRC)等消息进行配置。N表示第一预设值,用于表征终端在调度载波上的联合调度能力,取值可以是子帧数量,N为大于或等于1的整数。min()函数用于返回给定参数表中的最小值,max()函数用于返回给定参数表中的最大值。In formula (1), b represents the maximum value of the number of scheduling information on the scheduled carrier for all terminals or some terminals (including a specific terminal) on the scheduled carrier, and b is an integer greater than or equal to 1. The value of b can be configured by a protocol or by a system, for example, by a system information block (SIB) or by a radio resource control (RRC). The N indicates a first preset value, which is used to represent the joint scheduling capability of the terminal on the scheduling carrier. The value may be the number of subframes, and N is an integer greater than or equal to 1. The min() function is used to return the minimum value in the given parameter list, and the max() function is used to return the maximum value in the given parameter table.
其中,如果根据上述公式计算出的M值不是整数,则可对M近似取整(比如采用四舍五入方式取值)。Wherein, if the M value calculated according to the above formula is not an integer, the M may be approximated (for example, rounded off).
在一个示例中,M采用以下公式计算:
b=4,对于子载波间隔为15KHz的被调度载波,用于表征终端多子帧联合调度能力的第一预设值等于1,对于子载波间隔为60KHz的被调度载波,用于表征终端多子帧联合调度能力的第一预设值等于2。在子载波间隔为15KHz的载波调度子载波间隔为60KHz的载波的情况下,根据上述公式(1),M=4,N=2,则K=2,表示在调度载波的PDCCH内最多只承载两个调度信息(比如最多承载2个DCI,或者承载一个DCI且该DCI中最多包括2个用来指示被调度载波的数据信道资源的信息域)。在子载波间隔为60KHz的载波调度子载波间隔为15KHz的载波的情况下,根据上述公式(1),M=1/4,N=1,则K=1,表示在调度载波的PDCCH上最多只承载一个调度信息(比如最多承载1个DCI,或者承载一个DCI且该DCI中最多包括1个用来指示被调度载波的数据信道资源的信息域)。
In one example, M is calculated using the following formula: b=4, for a scheduled carrier with a subcarrier spacing of 15 kHz, the first preset value used to characterize the joint scheduling capability of the terminal multi-subframe is equal to 1, and the scheduled carrier with a subcarrier spacing of 60 kHz is used to characterize the terminal. The first preset value of the subframe joint scheduling capability is equal to two. In the case of a carrier with a carrier spacing of 15 kHz and a subcarrier spacing of 60 kHz, according to the above formula (1), M=4, N=2, then K=2, indicating that at most only the PDCCH in the scheduling carrier is carried. Two scheduling information (such as carrying at most 2 DCIs, or carrying one DCI and including at most 2 information fields for indicating data channel resources of the scheduled carriers). In the case of a carrier with a carrier spacing of 60 kHz and a subcarrier spacing of 15 kHz, according to the above formula (1), M=1/4, N=1, then K=1, indicating that the PDCCH on the scheduling carrier is the most. Only one scheduling information is carried (for example, a maximum of one DCI is carried, or one DCI is carried and the DCI includes at most one information field for indicating the data channel resource of the scheduled carrier).
在另外的一个示例中,M采用以下公式计算:
b=4,15KHz载波对应的频率资源上的一个时域单元(本例中以一个时域单元为一个时隙为例描述)包含7个OFDM符号,该时隙的长度为0.5ms;在60HKz载波对应的频率资源上的一个时域单元(本例中以一个时域单元为一个时隙为例描述)包含14个OFDM符号,该时隙的长度为0.25ms,在15KHz和60KHz载波上终端的用于表征最大多子帧联合调度能力的第一预设值分别等于1和2(即15KHz载波作为被调度载波时N=1,60KHz载波作为被调度载波时N=2);60KHz子载波调度15KHz子载波时,M=0.25/0.5=1/2,M/N=1/2,K=1,即PDCCH搜索空间内最多只承载一个DCI;15KHz载波调度60KHz载波时,对(0.5ms/0.25ms)取值,计算结果为M=2,M/N=1,K=2,即PDCCH搜索空间内最多只承载一个DCI。
In another example, M is calculated using the following formula: b=4, a time domain unit on the frequency resource corresponding to the 15KHz carrier (in this example, one time domain unit is a time slot as an example), including 7 OFDM symbols, the length of the time slot is 0.5 ms; at 60 HKz A time domain unit on the frequency resource corresponding to the carrier (described in this example with one time domain unit as a time slot as an example) includes 14 OFDM symbols, the length of the time slot is 0.25 ms, and the terminal is on the 15 kHz and 60 kHz carriers. The first preset value for characterizing the maximum multi-subframe joint scheduling capability is equal to 1 and 2 respectively (ie, N=1 when the 15KHz carrier is the scheduled carrier, and N=2 when the 60KHz carrier is the scheduled carrier); 60KHz subcarrier When scheduling 15KHz subcarriers, M=0.25/0.5=1/2, M/N=1/2, K=1, that is, at most one DCI is carried in the PDCCH search space; when the 15KHz carrier is scheduled to 60KHz carrier, (0.5ms) The value of /0.25ms) is calculated as M=2, M/N=1, and K=2, that is, at most one DCI is carried in the PDCCH search space.
方法2:确定第一比值,该第一比值的计算方法同方法1。若该第一比值大于1,则调度信息数量的最大值等于该第一比值,若该第一比值小于等于1,则调度信息数量的最大值等于1。Method 2: Determine a first ratio, which is calculated in the same manner as Method 1. If the first ratio is greater than 1, the maximum value of the number of scheduling information is equal to the first ratio. If the first ratio is less than or equal to 1, the maximum number of scheduling information is equal to 1.
上述方法2可表示为以下公式(2):The above method 2 can be expressed as the following formula (2):
K=max(1,M/N)……………………………………(2)K=max(1,M/N)....................................(2)
公式(2)中,b、N的取值和含义同公式(1)。In formula (2), the values and meanings of b and N are the same as formula (1).
方法3:确定第一比值与第二设定值的乘积,该第一比值等于被调度载波的子载波间隔与调度载波的子载波间隔的第二比值除以上述第一预设值所指示的最大时域单元的数量。若该乘积大于1且小于第一设定值,则调度信息数量的最大值等于所述乘积,若该乘积大于1且大于等于第一设定值,则调度信息数量的最大值等于所述第一设定值,若该乘积小于等于1,则将调度信息数量的最大值等于1。其中,第一设定值的取值和含义与方法1中的相同。该第二设定值表示在调度载波上允许联合调度的子帧数量的最大值,可由协议规定或系统配置。Method 3: Determine a product of a first ratio and a second set value, the first ratio being equal to a second ratio of a subcarrier spacing of the scheduled carrier to a subcarrier spacing of the scheduling carrier divided by the first preset value The number of maximum time domain units. If the product is greater than 1 and less than the first set value, the maximum value of the number of scheduling information is equal to the product. If the product is greater than 1 and greater than or equal to the first set value, the maximum number of scheduling information is equal to the first A set value, if the product is less than or equal to 1, the maximum number of scheduling information is equal to one. The value and meaning of the first set value are the same as those in the method 1. The second set value represents the maximum number of subframes allowed to be jointly scheduled on the scheduled carrier, which may be specified by the protocol or configured by the system.
上述方法3可表示为以下公式(3):The above method 3 can be expressed as the following formula (3):
K=min(b,max(1,L*M/N))……………………………(3)K=min(b,max(1,L*M/N))..............................(3)
公式(3)中,b、N的取值和含义同公式(1)。L为调度载波上对应的联合调度能力,L为大于等于1的整数。In formula (3), the values and meanings of b and N are the same as formula (1). L is the corresponding joint scheduling capability on the scheduling carrier, and L is an integer greater than or equal to 1.
在一个示例中,b=4,对于子载波间隔为60KHz的被调度载波,用于表征终端的多子帧联合调度能力的第一预设值等于2(即N=2),在子载波间隔为15KHz的调度载波上最多联合调度的子帧数量为2(即L=2)。在子载波间隔为15KHz的载波调度子载波间隔为60KHz的载波的情况下,M=4,N=2,则K=4。In one example, b=4, for a scheduled carrier with a subcarrier spacing of 60 KHz, the first preset value for characterizing the multi-subframe joint scheduling capability of the terminal is equal to 2 (ie, N=2), at the subcarrier spacing. The maximum number of jointly scheduled subframes on the 15KHz scheduled carrier is 2 (ie, L=2). In the case of a carrier with a subcarrier spacing of 15 kHz and a carrier subcarrier spacing of 60 kHz, M=4, N=2, then K=4.

K=min(b,max(1,M))K=min(b,max(1,M))
公式(4)中,b的取值和含义同公式(1),M的计算公式同公式(1)中的相关说明。In formula (4), the value and meaning of b are the same as formula (1), and the formula for calculating M is the same as that in formula (1).

图5示例性的示出了本申请实施例提供的由网络设备执行的调度信息传输的通用流程,该流程以调度载波和被调度载波为例描述,但可适用于其他频率资源调度粒度。如图所示,该流程可包括:FIG. 5 exemplarily shows a general flow of scheduling information transmission performed by a network device according to an embodiment of the present application. The flow is described by taking a scheduling carrier and a scheduled carrier as an example, but is applicable to other frequency resource scheduling granularities. As shown, the process can include:
S501:网络设备确定终端的调度信息的数量,所述调度信息位于物理下行控制信道, 用于在调度载波上指示被调度载波的数据信道资源,所述调度信息的数量小于或等于调度信息数量的最大值。S501: The network device determines the number of the scheduling information of the terminal, where the scheduling information is located on the physical downlink control channel, and is used to indicate the data channel resource of the scheduled carrier on the scheduling carrier, where the quantity of the scheduling information is less than or equal to the number of scheduling information. Maximum value.
其中,调度信息数量的最大值可根据被调度载波的子载波间隔和调度载波的子载波间隔确定的,或者,根据被调度载波的子载波间隔、调度载波的子载波间隔、上述用于表征终端联合调度能力的第一预设值确定的。具体确定方法如前述实施例所述,在此不再重复。The maximum number of scheduling information may be determined according to a subcarrier spacing of the scheduled carrier and a subcarrier spacing of the scheduling carrier, or according to a subcarrier spacing of the scheduled carrier, a subcarrier spacing of the scheduling carrier, and the foregoing characterizing the terminal. The first preset value of the joint scheduling capability is determined. The specific determination method is as described in the foregoing embodiment, and is not repeated here.
其中,如前述实施例所述,所述数据信道可包括PDSCH和/或PUSCH。Wherein, as described in the foregoing embodiments, the data channel may include a PDSCH and/or a PUSCH.
在S501中,网络设备可根据终端数据传输情况和/或终端的信道质量等,确定终端的调度信息的数量,并保证确定出的调度信息的数量小于或等于调度信息数量的最大值。以对终端的下行传输进行调度为例,基站可根据终端的数据量大小和信道质量指示(Channel Quality Indicator,CQI)确定具体使用几个DCI为该终端调度几个时隙的下行传输,当针对该终端的大量数据到达时,基站可根据终端的用户数据决定在60KHz子载波上将时域资源用满,因此确定发送2个DCI,每个DCI指示占用2个60KHz子载波对应的时隙。当针对该终端的数据量较小时,基站确定发送1个DCI,以指示占用1个或2个60KHz子载波对应的时隙。In S501, the network device may determine the number of scheduling information of the terminal according to the terminal data transmission situation and/or the channel quality of the terminal, and ensure that the determined number of scheduling information is less than or equal to the maximum value of the scheduling information. Taking the downlink transmission of the terminal as an example, the base station may determine, according to the data size of the terminal and the channel quality indicator (CQI), the downlink transmission that uses several DCIs to schedule several times for the terminal, when When a large amount of data of the terminal arrives, the base station may decide to use the time domain resource to be full on the 60 kHz subcarrier according to the user data of the terminal. Therefore, it is determined that two DCIs are transmitted, and each DCI indication occupies two time slots corresponding to the 60 kHz subcarrier. When the amount of data for the terminal is small, the base station determines to transmit one DCI to indicate that one or two 60KHz subcarriers corresponding to the time slot are occupied.
进一步地,不同子载波间隔的载波间跨载波调度时,调度的基本时间单位可由调度载波和被调度载波上基本时间单位较长的一方决定。例如,在15KHz子载波和60KHz子载波上进行跨载波调度时,15KHz子载波上的一个时隙表示为a ms(如a=0.5ms),60KHz子载波上的一个时隙对应为b ms,b=a/4(如b=0.125ms),则此时跨载波调度的时隙长度为a ms。Further, when inter-carrier cross-carrier scheduling with different sub-carrier intervals, the basic time unit of scheduling may be determined by the longer one of the scheduling carrier and the basic time unit on the scheduled carrier. For example, when performing cross-carrier scheduling on 15KHz subcarriers and 60KHz subcarriers, one slot on a 15KHz subcarrier is represented as a ms (eg, a=0.5ms), and one slot on a 60KHz subcarrier corresponds to b ms. b=a/4 (eg b=0.125ms), then the time slot of the cross-carrier scheduling is a ms.
S502:网络设备根据确定的调度信息的数量,使用调度载波发送调度信息。S502: The network device sends scheduling information by using a scheduling carrier according to the determined number of scheduling information.
基于上述流程,在一个例子中,S501中,网络设备可确定终端的一个搜索空间内DCI的数量;在S502中,网络设备可在该搜索空间内向终端发送DCI。其中,本实施例中的PDCCH搜索空间与LTE及NR中讨论的PDCCH或CORESET上的搜索空间定义一致。Based on the above flow, in an example, in S501, the network device may determine the number of DCIs in one search space of the terminal; in S502, the network device may send the DCI to the terminal in the search space. The PDCCH search space in this embodiment is consistent with the search space definition on the PDCCH or CORESET discussed in LTE and NR.
其中,如前述实施例所述,所述调度信息可以指示一个或多个时域单元中的被调度载波的数据信道资源。可选地,所述一个或多个时域单元的数量小于或等于上述用于表征终端联合调度能力的第一预设值所指示的该调度信息可以调度的最大时域单元的数量。比如,在时域单元为子帧的情况下,一个DCI可以指示一个或多个子帧中的被调度载波的数据信道资源,若为多个子帧,则该多个子帧的数量小于或等于用于表征多子帧联合调度能力的第一预设值所指示的最大子帧数量。再比如,在时域单元为时隙的情况下,一个DCI可以指示一个或多个时隙中的被调度载波的数据信道资源,若为多个时隙,则该多个时隙的数量小于或等于用于表征多时隙联合调度能力的第一预设值所指示的最大时隙数量。The scheduling information may indicate data channel resources of the scheduled carriers in one or more time domain units, as described in the foregoing embodiments. Optionally, the number of the one or more time domain units is less than or equal to the number of maximum time domain units that can be scheduled by the scheduling information indicated by the first preset value for characterizing the joint scheduling capability of the terminal. For example, in a case where the time domain unit is a subframe, one DCI may indicate a data channel resource of the scheduled carrier in one or more subframes, and if it is multiple subframes, the number of the multiple subframes is less than or equal to The maximum number of subframes indicated by the first preset value characterizing the multi-subframe joint scheduling capability. For another example, in a case where the time domain unit is a time slot, one DCI may indicate a data channel resource of the scheduled carrier in one or more time slots, and if there are multiple time slots, the number of the multiple time slots is smaller than Or equal to the maximum number of time slots indicated by the first preset value used to characterize the multi-slot joint scheduling capability.
可选地,调度信息指示多个时域单元中的被调度载波的数据信道资源时,所述多个时域单元中,每个时域单元中的被调度载波均独立承载传输块,或者全部或者部分时域单元中的被调度载波联合承载传输块。Optionally, when the scheduling information indicates the data channel resource of the scheduled carrier in the multiple time domain units, the scheduled carriers in each of the multiple time domain units independently carry the transport block, or all Or the scheduled carriers in the partial time domain unit jointly bear the transport block.
比如,在调度信息为DCI的情况下,在一个例子中,网络设备通过DCI指示X个(X为大于1的整数)子帧中的被调度载波的数据信道资源,这X个子帧中,每个子帧独立承载一个传输块(Transmission Block,TB),或者承载两个采用空分复用的传输块,每个子帧传输的传输块可以互不相同。在另一个例子中,网络设备通过DCI指示X个(X为大于1的整数)子帧中的被调度载波的数据信道资源,这X个子帧中,有至少2个子帧联合承 载一个传输块,或者联合承载两个采用空分复用的传输块。For example, in the case where the scheduling information is DCI, in one example, the network device indicates, by DCI, X (X is an integer greater than 1) the data channel resource of the scheduled carrier, and each of the X subframes The subframes independently carry one Transmission Block (TB), or carry two transport blocks that use space division multiplexing, and the transport blocks transmitted in each subframe may be different from each other. In another example, the network device indicates, by DCI, data channel resources of the scheduled carriers in X (X is an integer greater than 1) subframes, and at least 2 subframes of the X subframes jointly carry one transport block. Or jointly carrying two transport blocks using space division multiplexing.
图6示例性地示出了通过多个DCI进行多子帧联合调度时子帧与传输块之间的映射关系。如图所示,网络设备可通过n个(n为大于等于1的整数)DCI指示X个(X为大于1的整数)子帧上被调度载波的数据信道资源。其中,第一个子帧和第二个子帧联合承载第一个传输块,第X个子帧独立承载第Y个传输块。一个DCI可以指示一个或多个子帧中的被调度载波的数据信道资源。可以看出,通过一个或多个DCI可指示Y个传输块在X个子帧上的映射与传输,其中,X>1,对于Y无限制,对于X与Y的关系也无限制。FIG. 6 exemplarily shows a mapping relationship between a subframe and a transport block when multi-subframe joint scheduling is performed by a plurality of DCIs. As shown, the network device may indicate X (X is an integer greater than 1) data channel resources of the scheduled carrier through n (n is an integer greater than or equal to 1) DCI. The first subframe and the second subframe jointly carry the first transport block, and the Xth subframe independently carries the Yth transport block. A DCI may indicate data channel resources of scheduled carriers in one or more subframes. It can be seen that the mapping and transmission of Y transport blocks on X subframes can be indicated by one or more DCIs, where X>1, there is no limit for Y, and there is no limit to the relationship between X and Y.
再比如,在调度信息为DCI中的信息域的情况下,在一个例子中,网络设备通过DCI中的多个信息域指示X个(X为大于1的整数)时隙中被调度载波的数据信道资源,这X个时隙中,每个时隙独立承载一个传输块,或者承载两个采用空分复用的传输块。在另一个例子中,网络设备通过DCI中的多个信息域指示X个(X为大于1的整数)时隙中的被调度载波的数据信道资源,这X个时隙中,有至少2个时隙联合承载一个传输块,或者联合承载两个采用空分复用的传输块。For another example, in the case that the scheduling information is an information domain in the DCI, in one example, the network device indicates, by using multiple information fields in the DCI, data of the X (X is an integer greater than 1) time slot in the scheduled carrier. Channel resources, each of the X time slots, each time slot carries one transport block independently, or carries two transport blocks that use space division multiplexing. In another example, the network device indicates, by using multiple information fields in the DCI, data channel resources of the X (X is an integer greater than 1) time slot, and at least 2 of the X time slots. The time slots jointly carry one transport block or jointly carry two transport blocks that use space division multiplexing.
图7示例性地示出了通过DCI中的多个信息域进行多时隙联合调度时时隙与传输块之间的映射关系。如图所示,网络设备可通过DCI中的n个(n为大于等于1的整数)信息域指示X个(X为大于1的整数)时隙上被调度载波的数据信道资源。其中,第一个时隙独立承载第一个传输块,第二个时隙独立承载第二个传输块,第X-1个时隙和第X个时隙联合承载第Y个传输块。一个信息域可以指示一个或多个时隙中的被调度载波的数据信道资源。可以看出,通过一个DCI中的一个或多个信息域可指示Y个传输块在X个时隙上的映射与传输,其中,X>1,对于Y无限制,对于X与Y的关系也无限制。FIG. 7 exemplarily shows a mapping relationship between a time slot and a transport block when multi-slot joint scheduling is performed by a plurality of information fields in the DCI. As shown in the figure, the network device may indicate X (X is an integer greater than 1) data channel resources of the scheduled carrier through the n (n is an integer greater than or equal to 1) information field in the DCI. The first time slot independently carries the first transport block, the second time slot independently carries the second transport block, and the X-1 time slot and the Xth time slot jointly carry the Yth transport block. An information field may indicate data channel resources of a scheduled carrier in one or more time slots. It can be seen that the mapping and transmission of Y transport blocks on X time slots can be indicated by one or more information fields in a DCI, where X>1, there is no restriction on Y, and the relationship between X and Y is also No limit.
进一步地,在调度信息为DCI中的信息域的情况下,一个信息域可以用于指示一个时域单元中的被调度载波的数据信道资源。一个信息域中可包括第一指示信息,一个信息域中的第一指示信息用于指示被调度载波是在该时域单元上独立承载传输块,还是与其他时域单元中的被调度载波联合承载传输块。比如参见图7,信息域1中包括的第一指示信息用于指示被调度载波在第二个时隙上独立承载第二个TB,信息域n中包括的第一指示信息用于指示被调度载波在第x-1个时隙上与其他时隙联合承载第Y个TB。Further, in the case that the scheduling information is an information domain in the DCI, one information field may be used to indicate a data channel resource of the scheduled carrier in one time domain unit. An information field may include first indication information, where the first indication information in an information field is used to indicate whether the scheduled carrier is independently carrying a transport block on the time domain unit, or is associated with a scheduled carrier in other time domain units. Carry the transport block. For example, referring to FIG. 7, the first indication information included in the information field 1 is used to indicate that the scheduled carrier independently carries the second TB on the second time slot, and the first indication information included in the information field n is used to indicate that the scheduled information is scheduled. The carrier carries the Yth TB in conjunction with other time slots on the x-1th time slot.
可选地,在调度信息为DCI的情况下,网络设备在发送的DCI中包括第一信息域,所述第一信息域用于指示网络设备发送的DCI的数量是一个还是多个。该第一信息域的长度可以是1比特,当然也可以是更多比特。比如,该第一信息域所承载的比特序列取值为0,表示网络设备发送一个DCI,该比特序列取值为1表示网络设备发送多个DCI。这样,若终端根据接收到的DCI中的第一信息域确定接收到的DCI的数量等于该第一信息域所指示的DCI数量,则停止接收网络设备发送的DCI,比如停止在当前PDCCH搜索空间继续搜索DCI,从而可以节省终端的处理开销,并可节省终端的电源开销。Optionally, in a case that the scheduling information is DCI, the network device includes a first information field in the sent DCI, where the first information field is used to indicate whether the number of DCIs sent by the network device is one or more. The length of the first information field may be 1 bit, and of course more bits. For example, the bit sequence carried by the first information field takes a value of 0, indicating that the network device sends a DCI, and the value of the bit sequence is 1 indicating that the network device sends multiple DCIs. In this way, if the terminal determines that the number of received DCIs is equal to the number of DCIs indicated by the first information field, the terminal stops receiving DCIs sent by the network device, such as stopping in the current PDCCH search space, according to the first information field in the received DCI. Continue to search for DCI, which can save the processing overhead of the terminal and save the power consumption of the terminal.
该第一信息域也可用来指示网络设备发送的DCI的数量。此种情况下,该第一信息域的长度可以是
个比特,K表示DCI数量的最大值,
表示上取整。比如,DCI数量的最大值为4,此种情况下,网络设备发送的DCI的数量可能是1个、2个、3个或4个,该第一信息域的长度为2个比特,若该第一信息域中承载的比特序列为00,则表示网络设备发送1个DCI,若该比特序列为01,表示网络设备发送2个DCI,若该比特序列为10,表示网络设备发送3个DCI,当该比特序列取值为11,表示网络设备发送4个DCI。这样,若终端根据接收到的DCI中的第一信息域确定网络设备发送的DCI的数量为一个, 则可停止接收网络设备发送的DCI,比如停止在当前PDCCH搜索空间继续搜索DCI,从而可以节省终端的处理开销,进而可节省终端的电源开销。
The first information field can also be used to indicate the number of DCIs sent by the network device. In this case, the length of the first information field may be Bits, K represents the maximum number of DCIs, The representation is rounded up. For example, the maximum number of DCIs is 4. In this case, the number of DCIs sent by the network device may be 1, 2, 3, or 4. The length of the first information field is 2 bits. If the bit sequence carried in the first information field is 00, it indicates that the network device sends one DCI. If the bit sequence is 01, the network device sends two DCIs. If the bit sequence is 10, the network device sends three DCIs. When the bit sequence takes a value of 11, it means that the network device sends 4 DCIs. In this way, if the terminal determines that the number of DCIs sent by the network device is one according to the first information field in the received DCI, the terminal may stop receiving the DCI sent by the network device, for example, stop searching for the DCI in the current PDCCH search space, thereby saving The processing overhead of the terminal can further save the power consumption of the terminal.
图8示例性地示出了本申请实施例提供的由终端侧实现的调度信息传输流程,该流程以调度载波和被调度载波为例描述,但可适用于其他频率资源种类,比如BP。如图所示,该流程可包括:FIG. 8 exemplarily shows a scheduling information transmission flow implemented by a terminal side according to an embodiment of the present application. The flow is described by taking a scheduling carrier and a scheduled carrier as an example, but is applicable to other frequency resource types, such as BP. As shown, the process can include:
S801:终端确定调度信息的数量。其中,所述调度信息位于物理下行控制信道,用于在调度载波上指示被调度载波的数据信道资源,所述调度信息为DCI或DCI中的信息域,所述调度信息的数量小于或等于调度信息数量最大值。S801: The terminal determines the quantity of scheduling information. The scheduling information is located on a physical downlink control channel, and is used to indicate a data channel resource of the scheduled carrier on the scheduling carrier, where the scheduling information is an information domain in the DCI or DCI, and the quantity of the scheduling information is less than or equal to the scheduling. The maximum number of messages.
其中,调度信息数量的最大值可根据被调度载波的子载波间隔和调度载波的子载波间隔确定的,或者,根据被调度载波的子载波间隔、调度载波的子载波间隔、用于表征联合调度能力的第一预设值确定的。具体确定方法如前述实施例所述,在此不再重复。The maximum number of scheduling information may be determined according to the subcarrier spacing of the scheduled carrier and the subcarrier spacing of the scheduling carrier, or according to the subcarrier spacing of the scheduled carrier, the subcarrier spacing of the scheduling carrier, and used to characterize the joint scheduling. The first preset value of the ability is determined. The specific determination method is as described in the foregoing embodiment, and is not repeated here.
需要说明的是,图8所示的上述流程中涉及到的技术术语的含义,与前述实施例对这些技术术语的解释相同,比如,物理下行控制信道可以是PDCCH,数据信道可以是PDSCH和/或PUSCH。还需要说明的是,网络设备发送的DCI或DCI中包含的信息域的内容、结构以及与传输块之间的映射关系,可以与前述实施例相同,在此不再重复。本流程对网络设备如何确定DCI的数量或DCI中包含的信息域的数量不作限制,网络设备既可以采用前述实施例描述的方式确定DCI的数量或DCI中包含的信息域的数量,也可采用其他方法确定。It should be noted that the meanings of the technical terms involved in the foregoing process shown in FIG. 8 are the same as those of the foregoing embodiments. For example, the physical downlink control channel may be a PDCCH, and the data channel may be a PDSCH and/or Or PUSCH. It should be noted that the content, structure, and mapping relationship between the information domain and the transport block included in the DCI or the DCI transmitted by the network device may be the same as those in the foregoing embodiment, and are not repeated here. The process does not limit how the network device determines the number of DCIs or the number of information domains included in the DCI. The network device can determine the number of DCIs or the number of information domains included in the DCI in the manner described in the foregoing embodiments. Other methods are ok.
S802:终端根据确定的调度信息的数量,在调度载波上接收调度信息。S802: The terminal receives scheduling information on the scheduling carrier according to the determined number of scheduling information.
该步骤中,终端可根据S801中确定的调度信息的数量,在调度载波的PDCCH搜索空间内接收调度信息。比如,若终端确定出DCI的数量为一个,则在调度载波的PDCCH搜索空间内搜索到一个DCI后即可停止搜索,以节省终端的处理开销,进而可节省电源开销。再比如,若终端确定出DCI的数量为两个,则在调度载波的PDCCH搜索空间内搜索到两个DCI后即可停止搜索,以节省终端的处理开销,进而可节省电源开销。可以看出,终端在确定当前接收的DCI的数量与S801中确定出的DCI数量相等时,即可停止DCI的搜索。In this step, the terminal may receive scheduling information in the PDCCH search space of the scheduling carrier according to the number of scheduling information determined in S801. For example, if the terminal determines that the number of DCIs is one, the search may be stopped after searching for a DCI in the PDCCH search space of the scheduling carrier, so as to save processing overhead of the terminal, thereby saving power consumption. For example, if the terminal determines that the number of DCIs is two, the search may be stopped after searching for two DCIs in the PDCCH search space of the scheduling carrier, so as to save processing overhead of the terminal, thereby saving power consumption. It can be seen that when the terminal determines that the number of currently received DCIs is equal to the number of DCIs determined in S801, the terminal can stop the DCI search.
可选地,在所述调度信息为DCI的情况下,基于上述流程的一个例子中,DCI中可包括第一信息域,该信息域用于指示所述网络设备发送的DCI的数量。在S802中,若终端根据接收到的DCI中的第一信息域确定接收到的DCI的数量等于该第一信息域所指示的DCI数量,则可停止接收网络设备发送的DCI,即停止在调度载波的PDCCH搜索空间内搜索DCI,以节省终端的处理开销,进而可节省电源开销。Optionally, in the case that the scheduling information is DCI, in an example of the foregoing process, the DCI may include a first information domain, where the information domain is used to indicate the number of DCIs sent by the network device. In S802, if the terminal determines, according to the first information field in the received DCI, that the number of received DCIs is equal to the number of DCIs indicated by the first information field, the terminal may stop receiving the DCI sent by the network device, that is, stop scheduling. The DCI is searched in the PDCCH search space of the carrier to save the processing overhead of the terminal, thereby saving power consumption.
可选地,在所述调度信息为DCI的情况下,基于上述流程的另一个例子中,DCI中可包括第一信息域,该信息域用于指示所述网络设备发送的DCI数量是一个还是多个。在S802中,若终端根据接收到的DCI中的第一信息域确定网络设备发送的DCI的数量为一个,则可停止接收网络设备发送的DCI,即停止在调度载波的PDCCH搜索空间内搜索DCI,以节省终端的处理开销,进而可节省电源开销。Optionally, in the case that the scheduling information is DCI, in another example of the foregoing process, the DCI may include a first information field, where the information field is used to indicate whether the number of DCIs sent by the network device is one or Multiple. In S802, if the terminal determines, according to the first information field in the received DCI, that the number of DCIs sent by the network device is one, the terminal may stop receiving DCI sent by the network device, that is, stop searching for DCI in the PDCCH search space of the scheduling carrier. In order to save the processing overhead of the terminal, thereby saving power consumption.

通过图9所示的流程可以看出,网络设备确定出DCI的数量后,向终端发送确定出的DCI的数量,或者发送与DCI数量相关的指示信息,这样可以使得终端根据网络设备发送的DCI的数量或指示信息接收DCI,比如在确定接收到的DCI数量与网络设备所发送的DCI数量相等时,即可停止在PDCCH空间内继续搜索DCI,从而可以节省终端的处理开销,进而可以节省终端的电源开销。It can be seen that, after the network device determines the number of DCIs, the network device sends the determined number of DCIs to the terminal, or sends indication information related to the number of DCIs, so that the terminal can enable the terminal to send DCI according to the network device. The number or indication information is received by the DCI. For example, when it is determined that the number of received DCIs is equal to the number of DCIs sent by the network device, the DCI can be continuously searched in the PDCCH space, thereby saving processing overhead of the terminal, thereby saving the terminal. Power overhead.
