Hence, the embodiments of the present application facilitates implementation of PDCCH monitoring under the condition of supporting multi-carrier scheduling, and implement, by means of multi-carrier scheduling, the possibility of reducing the complexity of PDCCH monitoring to save power consumption.
Description
本申请涉及通信技术领域,尤其涉及一种物理下行控制信道监听方法与装置、终端设备和网络设备。The present application relates to the technical field of communications, and in particular to a method and device for monitoring a physical downlink control channel, terminal equipment, and network equipment.
在载波聚合(Carrier Aggregation,CA)场景中,第三代合作伙伴计划(3rd generation partnership project,3GPP)所制定的标准协议规定,一个小区要么只支持自载波调度(self-carrier scheduling),要么只支持跨载波调度(cross-carrier sheduling)。In the carrier aggregation (Carrier Aggregation, CA) scenario, the standard protocol formulated by the 3rd generation partnership project (3GPP) stipulates that a cell either only supports self-carrier scheduling (self-carrier scheduling), or only Supports cross-carrier sheduling.
目前,一个小区上发送的物理下行控制信道(Physical Downlink Control Channel,PDCCH)所承载的下行控制信息(Downlink Control Information,DCI)只能调度一个载波(一个分量载波(Component Carrier,CC)或一个小区)内的数据传输。Currently, the downlink control information (DCI) carried by the Physical Downlink Control Channel (PDCCH) sent on a cell can only schedule one carrier (one component carrier (Component Carrier, CC) or one cell ) within the data transfer.
由于一个DCI只能调度一个载波(或一个小区)内的数据传输,因此这将导致在载波聚合场景下,尤其聚合的小区个数较多,且业务量较大时,终端设备需要花费大量的功耗去监听(或者盲检)各小区的PDCCH。例如,当聚合有16个小区,且下行业务量较大时,若需要在该16个小区上调度下行数据,且一个DCI只能调度一个小区内的数据传输,则终端设备需要分别去监听各个小区的PDCCH,总共需要监听16个PDCCH(1个PDCCH承载一个DCI),从而导致终端设备在监听PDCCH上花费大量的功耗。对此,对于如何降低PDCCH的监听复杂度以节省功耗,还需要进一步研究。Since one DCI can only schedule data transmission in one carrier (or one cell), this will cause the terminal device to spend a lot of time in the carrier aggregation scenario, especially when the number of aggregated cells is large and the traffic volume is large. Power consumption is used to monitor (or blindly detect) the PDCCH of each cell. For example, when there are 16 cells aggregated and the downlink traffic volume is large, if downlink data needs to be scheduled on the 16 cells, and one DCI can only schedule data transmission in one cell, the terminal device needs to monitor each The PDCCH of the cell needs to monitor 16 PDCCHs in total (one PDCCH carries one DCI), which causes the terminal device to consume a lot of power consumption in monitoring the PDCCH. In this regard, further research is needed on how to reduce the monitoring complexity of the PDCCH to save power consumption.

本申请实施例中,网络设备可以是一个独立的节点以实现上述基站的功能或者,网络设备可以包括两个或多个独立的节点以实现上述基站的功能。例如,网络设备包括集中式单元(centralized unit,CU)和分布式单元(distributed unit,DU),如gNB-CU和gNB-DU。进一步的,在本申请的另一些实施例中,网络设备还可以包括有源天线单元(active antenna unit,AAU)。其中,CU实现网络设备的一部分功能,DU实现网络设备的另一部分功能。比如,CU负责处理非实时协议和服务,实现无线资源控制(radio resource control,RRC)层、服务数据适配(service data adaptation protocol,SDAP)层、分组数据汇聚(packet data convergence protocol,PDCP)层的功能。DU负责处理物理层协议和实时服务,实现无线链路控制(radio link control,RLC)层、媒体接入控制(medium access control,MAC)层和物理(physical,PHY)层的功能。另外,AAU可以实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息,或者由PHY层的信息转变而来,因此,在该网络部署下,高层信令(如RRC信令)可以认为是由DU发送的,或者由DU和AAU共同发送的。可以理解的是,网络设备可以包括CU、DU、AAU中的至少一个。另外,可以将CU划分为RAN中的网络设备,或者,也可以将CU划分为核心网中的网络设备,对此不做具体限定。In this embodiment of the present application, the network device may be an independent node to implement the functions of the base station, or the network device may include two or more independent nodes to implement the functions of the base station. For example, a network device includes a centralized unit (centralized unit, CU) and a distributed unit (distributed unit, DU), such as gNB-CU and gNB-DU. Further, in some other embodiments of the present application, the network device may further include an active antenna unit (active antenna unit, AAU). Among them, the CU implements a part of the functions of the network equipment, and the DU implements another part of the functions of the network equipment. For example, CU is responsible for processing non-real-time protocols and services, implementing radio resource control (radio resource control, RRC) layer, service data adaptation protocol (service data adaptation protocol, SDAP) layer, packet data convergence (packet data convergence protocol, PDCP) layer function. The DU is responsible for processing physical layer protocols and real-time services, realizing the functions of the radio link control (radio link control, RLC) layer, medium access control (medium access control, MAC) layer and physical (physical, PHY) layer. In addition, the AAU can implement some physical layer processing functions, radio frequency processing and related functions of active antennas. Since the information of the RRC layer will eventually become the information of the PHY layer, or be transformed from the information of the PHY layer, under this network deployment, high-level signaling (such as RRC signaling) can be considered to be sent by the DU, or Sent jointly by DU and AAU. It can be understood that the network device may include at least one of CU, DU, and AAU. In addition, the CU can be divided into network devices in the RAN, or the CU can also be divided into network devices in the core network, which is not specifically limited.

Wherein, the cell may be a macro cell, a small cell, a metro cell, a micro cell, a pico cell, a femto cell, and the like.
4)示例性说明4) Exemplary description
结合上述描述,下面对本申请实施例的通信系统做一个示例性说明。In combination with the foregoing description, an exemplary description of the communication system in the embodiment of the present application is given below.
示例性的,如图1所示,通信系统10可以包括终端设备110和网络设备120。网络设备120可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域内的终端设备110进行通信。Exemplarily, as shown in FIG. 1 , a communication system 10 may include a terminal device 110 and a network device 120 . The network device 120 can provide communication coverage for a specific geographical area, and can communicate with the terminal device 110 located in the coverage area.
需要说明的是,图1仅为一种通信系统的网络架构的举例说明,对本申请实施例的通信系统的网络架构并不构成限定。It should be noted that FIG. 1 is only an illustration of a network architecture of a communication system, and does not limit the network architecture of the communication system in the embodiment of the present application.
例如,通信系统10还可以包括多个网络设备,并且每个网络设备的覆盖范围内可以包括一定数量的终端设备,对此不作具体限定。For example, the communication system 10 may also include multiple network devices, and the coverage of each network device may include a certain number of terminal devices, which is not specifically limited.
又例如,通信系统10还可以包括网络控制器、移动管理实体等其他网络实体,对此不作具体限定。For another example, the communication system 10 may also include other network entities such as a network controller and a mobility management entity, which is not specifically limited.
又例如,通信系统10中的网络设备与终端设备之间的通信可以为无线通信或者有线通信,对此不作具体限制。For another example, the communication between the network device and the terminal device in the communication system 10 may be wireless communication or wired communication, which is not specifically limited.
2、PDCCH2. PDCCH
PDCCH上承载的净荷(payload)称为DCI,也就是说,PDCCH承载DCI。The payload (payload) carried on the PDCCH is called DCI, that is, the PDCCH carries DCI.
一个载波可以有多个控制资源集(control-resource set,CORESET),CORESET会将资源单元映射到控制信道单元(Control Channel Element,CCE),一个或多个CCE聚合在一起来承载PDCCH,而终端设备可以通过盲检在搜索空间(search space)中检测网络是否有PDCCH发送给自己。A carrier can have multiple control resource sets (control-resource set, CORESET), CORESET will map resource elements to control channel elements (Control Channel Element, CCE), one or more CCEs are aggregated together to carry PDCCH, and the terminal The device can detect whether the network has a PDCCH sent to itself in the search space (search space) through blind detection.
CCE是构成PDCCH的基本资源单元。一个PDCCH可以使用1、2、4、8、16个CCE。其中,使
用的CCE的个数可以称为聚合等级(aggregation level)。也就是说,一个PDCCH可以由若干个CCE聚合而成。A CCE is a basic resource unit constituting a PDCCH. One PDCCH can use 1, 2, 4, 8, 16 CCEs. Among them, make The number of CCEs used may be called an aggregation level (aggregation level). That is to say, one PDCCH can be aggregated by several CCEs.
一个CCE可以包括6个资源单元组(Resource Element Group,REG),每个REG可以包括一个OFDM符号上的一个或多个资源块(Resource Block,RB)。A CCE may include 6 resource element groups (Resource Element Group, REG), and each REG may include one or more resource blocks (Resource Block, RB) on an OFDM symbol.
CORESET是5G NR新提出的一个时频域资源集的概念。这是因为在5G NR中,通信系统的传输带宽比较大,而终端设备的支持能力不尽相同。为了适配不同的带宽,同时降低PDCCH的盲检复杂度,从而通过CORESET约束PDCCH的时频域资源调度。CORESET is a new concept of time-frequency domain resource set proposed by 5G NR. This is because in 5G NR, the transmission bandwidth of the communication system is relatively large, and the support capabilities of terminal devices are not the same. In order to adapt to different bandwidths and reduce the complexity of PDCCH blind detection, the time-frequency domain resource scheduling of PDCCH is constrained by CORESET.
CORESET可以有多个搜索空间,而一个搜索空间是一组具有相同聚合等级的CCE所构成的候选控制信道。由于CCE有多个聚合等级,因此一个终端设备可以对应多个搜索空间。CORESET can have multiple search spaces, and a search space is a candidate control channel composed of a group of CCEs with the same aggregation level. Since CCE has multiple aggregation levels, one terminal device can correspond to multiple search spaces.
3、载波聚合3. Carrier aggregation
(1)分量载波(Component Carrier,CC)、主小区(Primary Cell,PCell)、辅小区(Secondary Cell,SCell)(1) Component Carrier (CC), primary cell (Primary Cell, PCell), secondary cell (Secondary Cell, SCell)
在载波聚合中,多个载波可以聚合在一起,同时为一个终端设备服务。如此,终端设备通过载波聚合可以获得更大的服务带宽,以及获得更大的传输速率。其中,载波聚合不需要所有载波在频域上连续,甚至无需限制在同一个频段内。In carrier aggregation, multiple carriers can be aggregated together to serve one terminal device at the same time. In this way, the terminal device can obtain a larger service bandwidth and a larger transmission rate through carrier aggregation. Among them, carrier aggregation does not require all carriers to be continuous in the frequency domain, or even limited to the same frequency band.
NR标准的载波聚合可以支持最多16个载波的聚合。这些载波可以是不同的载波带宽,也可以是不同的双工方式。The carrier aggregation of the NR standard can support the aggregation of up to 16 carriers. These carriers may have different carrier bandwidths or different duplex modes.
另外,聚合的载波也可以称为分量载波。In addition, an aggregated carrier may also be called a component carrier.
例如,载波聚合有5个载波,该5个载波分别为分量载波0(CC0)、分量载波1(CC1)、分量载波2(CC2)、分量载波3(CC3)、分量载波4(CC4)。For example, there are 5 carriers in carrier aggregation, and the 5 carriers are component carrier 0 (CC0), component carrier 1 (CC1), component carrier 2 (CC2), component carrier 3 (CC3), and component carrier 4 (CC4).
对于终端设备,支持载波聚合的终端设备可以同时在多个分量载波上收发数据;不支持载波聚合的终端设备可以在一个分量载波上收发数据。For terminal devices, a terminal device that supports carrier aggregation can simultaneously send and receive data on multiple component carriers; a terminal device that does not support carrier aggregation can send and receive data on one component carrier.
在NR标准对载波聚合的描述中,经常使用小区的概念。本申请实施例可以将一个载波(或分量载波)称为或看作一个小区。因此,聚合的载波,也可以理解为聚合的小区。同理,支持载波聚合的终端设备可以同时在多个载波(或分量载波)上收发数据,也就是说,支持载波聚合的终端设备可以同时在多个小区内收发数据。In the description of carrier aggregation in NR standard, the concept of cell is often used. In the embodiment of the present application, a carrier (or component carrier) may be called or regarded as a cell. Therefore, an aggregated carrier may also be understood as an aggregated cell. Similarly, a terminal device supporting carrier aggregation can simultaneously send and receive data on multiple carriers (or component carriers), that is, a terminal device supporting carrier aggregation can simultaneously send and receive data in multiple cells.
例如,载波聚合有5个载波,该5个载波分别为CC0、CC1、CC2、CC3、CC4。其中,CC0为小区0,或者说CC0对应小区0(小区0对应CC0)。同理,CC1为小区1,CC2为小区2,CC3为小区3,CC4为小区4。For example, there are 5 carriers in carrier aggregation, and the 5 carriers are CC0, CC1, CC2, CC3, and CC4 respectively. Wherein, CC0 is cell 0, or CC0 corresponds to cell 0 (cell 0 corresponds to CC0). Similarly, CC1 is cell 1, CC2 is cell 2, CC3 is cell 3, and CC4 is cell 4.
对于这些聚合的小区中,只有一个小区称为主小区,而其他小区则称为辅小区。其中,主小区可以是终端设备接入网络所使用的小区,而辅小区可以是终端设备进入连接态后由网络配置的。网络可以快速地激活或者去激活辅小区来满足业务需求的变化。不同的终端设备可以配置不同的小区作为主小区。Among these aggregated cells, only one cell is called a primary cell, while the other cells are called secondary cells. Wherein, the primary cell may be a cell used by the terminal device to access the network, and the secondary cell may be configured by the network after the terminal device enters the connected state. The network can quickly activate or deactivate the secondary cell to meet changes in service requirements. Different terminal devices can configure different cells as primary cells.
(2)自载波调度(self-carrier scheduling)(2) Self-carrier scheduling (self-carrier scheduling)
目前,在载波聚合场景中,一个小区要么只支持自载波调度,要么只支持跨载波调度。Currently, in a carrier aggregation scenario, a cell either only supports self-carrier scheduling or cross-carrier scheduling.
在本申请实施例中,自载波调度,可以表示为,小区的调度授权和传输数据在同一个载波上发送。In the embodiment of the present application, the self-carrier scheduling may be expressed as that the scheduling grant of the cell and the transmission data are sent on the same carrier.
例如,若小区0支持自载波调度(或者小区0配置为自载波调度),则终端设备可以在小区0对应的CC0上监听小区0的PDCCH,并通过该PDCCH所承载的DCI来获取相关的调度授权。最后,终端设备通过该调度授权在CC0上进行传输数据的发送。可见,小区0的调度授权和传输数据在CC0上发送。For example, if cell 0 supports self-carrier scheduling (or cell 0 is configured as self-carrier scheduling), the terminal device can monitor the PDCCH of cell 0 on CC0 corresponding to cell 0, and obtain related scheduling through the DCI carried by the PDCCH authorized. Finally, the terminal device sends transmission data on CC0 through the scheduling authorization. It can be seen that the scheduling grant and transmission data of cell 0 are sent on CC0.
(3)跨载波调度(cross-carrier sheduling)(3) Cross-carrier scheduling (cross-carrier sheduling)
在本申请实施例中,跨载波调度,可以表示为,小区的调度授权和传输数据在不同的载波上发送。In this embodiment of the present application, cross-carrier scheduling may be expressed as that the scheduling grant and transmission data of a cell are sent on different carriers.
需要说明的是,一个小区多载波调度另一个小区,则该另一个小区可以说是支持跨载波调度。It should be noted that if one cell schedules another cell with multiple carriers, then the other cell can be said to support cross-carrier scheduling.
例如,若小区0可以跨载波调度小区1,则终端设备只能在小区0对应的CC0上监听PDCCH,并通过PDCCH所承载的DCI来获取小区1的调度授权(或者说,该DCI只能调度小区1对应的CC1内的数据传输),而终端设备不能在小区1对应的CC1上监听PDCCH来获取自身的调度授权。最后,终端设备通过该调度授权在CC1上进行传输数据的发送。可见,小区0的调度授权在CC0上发送,而小区1的传输数据在CC1上发送。此时,本申请实施例可以说,小区1支持跨载波调度(或者小区1配置为跨载波调度)。For example, if cell 0 can schedule cell 1 across carriers, the terminal device can only monitor the PDCCH on CC0 corresponding to cell 0, and obtain the scheduling authorization of cell 1 through the DCI carried by the PDCCH (in other words, the DCI can only schedule data transmission in the CC1 corresponding to the cell 1), and the terminal device cannot monitor the PDCCH on the CC1 corresponding to the cell 1 to obtain its own scheduling authorization. Finally, the terminal device sends transmission data on CC1 through the scheduling authorization. It can be seen that the scheduling grant of cell 0 is sent on CC0, and the transmission data of cell 1 is sent on CC1. At this point, in this embodiment of the present application, it can be said that cell 1 supports cross-carrier scheduling (or cell 1 is configured to be cross-carrier scheduling).
在本申请实施例中,DCI可以包括载波指示字段(carrier indicator field,CI field)。高层信令可以指示是否配置跨载波调度。例如,网络可以通过高层参数(如RRCConnectionReconfiguration中的crossCarrierSchedulingConfig)来配置某个小区的跨载波调度。当跨载波调度被配置时,需要通过该载
波指示字段来指示该载波指示字段的DCI是针对哪个分量载波。In this embodiment of the present application, the DCI may include a carrier indicator field (carrier indicator field, CI field). High-level signaling may indicate whether to configure cross-carrier scheduling. For example, the network can configure cross-carrier scheduling of a certain cell through high-level parameters (such as crossCarrierSchedulingConfig in RRCConnectionReconfiguration). When cross-carrier scheduling is configured, it is necessary to pass the The carrier indicator field is used to indicate which component carrier the DCI of the carrier indicator field is for.
4、PDCCH的监听能力(盲检能力)4. PDCCH monitoring capability (blind detection capability)
终端设备根据相应的搜索空间集在配置有PDCCH监听的每个激活的服务小区上的一个或多个CORESET中监听一组PDCCH候选。其中,监听(或盲检),可以理解为,接收每个PDCCH候选并根据监听的DCI格式进行解码。The terminal device monitors a group of PDCCH candidates in one or more CORESETs on each activated serving cell configured with PDCCH monitoring according to the corresponding search space set. Wherein, monitoring (or blind detection) can be understood as receiving each PDCCH candidate and decoding it according to the monitored DCI format.
由于终端设备的硬件计算资源、时延和功耗的约束,以及调度灵活度的考量,因此PDCCH的监听能力是在进行PDCCH协议设计时的一个重要考量因素。Due to the constraints of hardware computing resources, time delay and power consumption of the terminal equipment, and the consideration of scheduling flexibility, the monitoring capability of the PDCCH is an important consideration when designing the PDCCH protocol.
1)时隙(slot)、(X,Y)组合的间隔(span)、(XS,YS)组合的多时隙1) Time slot (slot), (X, Y) combined interval (span), (X S , Y S ) combined multi-slot
若向终端设备提供了针对一个服务小区的监听能力配置参数(monitoringCapabilityConfig),且monitoringCapabilityConfig=r15monitoringcapability,则终端设备可以获得一个指示(indication),并通过该指示确定在每个时隙(slot)内对于服务小区的PDCCH候选的最大个数或非重叠CCE的最大个数。If the monitoring capability configuration parameter (monitoringCapabilityConfig) for a serving cell is provided to the terminal device, and monitoringCapabilityConfig=r15monitoringcapability, the terminal device can obtain an indication (indication), and determine the The maximum number of PDCCH candidates or the maximum number of non-overlapping CCEs of the serving cell.

若未向终端设备提供monitoringCapabilityConfig,则终端设备监听服务小区上的PDCCH,以获取每个时隙内的PDCCH候选的最大个数和非重叠CCE的最大个数。If the monitoringCapabilityConfig is not provided to the terminal device, the terminal device monitors the PDCCH on the serving cell to obtain the maximum number of PDCCH candidates and the maximum number of non-overlapping CCEs in each time slot.
对于μ=0和μ=1对应的SCS配置,终端设备可以根据一个或多个(X,Y)组合来指示监听PDCCH的能力。For the SCS configuration corresponding to μ=0 and μ=1, the terminal device may indicate the ability to monitor the PDCCH according to one or more (X, Y) combinations.
一个span,是终端设备配置为监听PDCCH的时隙中的多个连续符号。A span is a plurality of consecutive symbols in a time slot in which the terminal device is configured to monitor the PDCCH.
每个PDCCH监听时机(monitoring occasion)在一个span内。Each PDCCH monitoring occasion (monitoring occasion) is within a span.
若终端设备根据(X,Y)组合的span在小区上监听PDCCH,则终端设备支持一个时隙的任何符号中的PDCCH监听时机,其中该时隙在两个连续span的第一个符号之间的具有X个符号的最小时间间隔。If the terminal device monitors the PDCCH on the cell according to the combined span of (X,Y), the terminal device supports the PDCCH monitoring opportunity in any symbol of a slot between the first symbols of two consecutive spans The smallest time interval with X symbols.
一个(X,Y)组合的span,从PDCCH监听时机开始的第一个符号开始,到PDCCH监听时机结束的最后一个符号结束,其中该span的符号数最多为Y。A span of (X, Y) combination starts from the first symbol at the beginning of the PDCCH monitoring opportunity and ends at the last symbol at the end of the PDCCH monitoring opportunity, wherein the number of symbols in the span is at most Y.
对于μ=5和μ=6的SCS配置,终端设备可以根据一个或多个(XS,YS)组合来指示监听PDCCH的能力,其中XS和YS是连续时隙的个数。For the SCS configuration of μ=5 and μ=6, the terminal device can indicate the ability to monitor the PDCCH according to one or more (X S , Y S ) combinations, where X S and Y S are the number of consecutive time slots.
如果终端设备根据(XS,YS)组合的多时隙在小区上监听PDCCH,则终端设备可以在YS个时隙的任何时隙中监听由专用高层信令提供的Type1-PDCCH CSS集、Type3-PDCCH CSS集和USS集的PDCCH,并且终端设备可以在XS个时隙的任何时隙中监视由SIB1提供的Type0/0A/2-PDCCH CSS集和Type1-PDCCH CSS集的PDCCH。终端设备可以根据(XS,YS)组合的XS个时隙内的所有搜索空间集合来确定监听的PDCCH候选的最大数量和非重叠CCE的最大数量。If the terminal device monitors the PDCCH on the cell according to the multi-slot combination of (X S , Y S ), the terminal device can monitor the Type1-PDCCH CSS set provided by dedicated high-level signaling in any time slot of the Y S time slots, The Type3-PDCCH CSS set and the PDCCH of the USS set, and the terminal device can monitor the Type0/0A/2-PDCCH CSS set and the Type1-PDCCH CSS set PDCCH provided by SIB1 in any time slot of X S slots. The terminal device may determine the maximum number of monitored PDCCH candidates and the maximum number of non-overlapping CCEs according to all search space sets within the (X S , Y S ) combined X S time slots.

5、一种PDCCH监听方法5. A PDCCH monitoring method
结合上述可知,在载波聚合场景中,一个小区要么只支持自载波调度,要么只支持跨载波调度。无论是自载波调度还是跨载波调度,终端设备需要按照PDCCH候选的最大个数限制或者非重叠CCE的最大个数限制进行PDCCH的监听(或盲检)以获取DCI。Based on the above, it can be seen that in the carrier aggregation scenario, a cell either only supports self-carrier scheduling, or only supports cross-carrier scheduling. Regardless of self-carrier scheduling or cross-carrier scheduling, the terminal device needs to monitor (or blindly detect) the PDCCH according to the maximum number of PDCCH candidates or the maximum number of non-overlapping CCEs to obtain DCI.
目前,一个小区上发送的PDCCH所承载的DCI只能调度一个载波(或者CC)内的数据传输,这将导致在载波聚合场景下,尤其聚合的小区个数较多,且业务量较大时,终端设备需要花费大量的功耗去监听(或者盲检)各小区的PDCCH。At present, the DCI carried by the PDCCH sent on a cell can only schedule data transmission in one carrier (or CC), which will lead to the carrier aggregation scenario, especially when the number of aggregated cells is large and the traffic volume is large. , the terminal device needs to spend a lot of power consumption to monitor (or blindly detect) the PDCCH of each cell.
例如,当聚合有16个小区,且下行业务量较大时,若需要在该16个小区上调度下行数据,且一个DCI只能调度一个小区内的数据传输,则终端设备需要分别去监听各个小区的PDCCH,总共需要监听16个PDCCH(1个PDCCH承载一个DCI),从而导致终端设备在监听PDCCH上花费大量的功耗。For example, when there are 16 cells aggregated and the downlink traffic volume is large, if downlink data needs to be scheduled on the 16 cells, and one DCI can only schedule data transmission in one cell, the terminal device needs to monitor each The PDCCH of the cell needs to monitor 16 PDCCHs in total (one PDCCH carries one DCI), which causes the terminal device to consume a lot of power consumption in monitoring the PDCCH.
为了降低PDCCH的监听复杂度以节省功耗,本申请实施例引入一个DCI可以调度多个载波(或多个CC)内的数据传输,即多载波调度,从而通过多载波调度实现降低PDCCH的监听复杂度以节省功耗。In order to reduce the monitoring complexity of PDCCH to save power consumption, the embodiment of this application introduces a DCI that can schedule data transmission in multiple carriers (or multiple CCs), that is, multi-carrier scheduling, so as to reduce the monitoring of PDCCH through multi-carrier scheduling complexity to save power.
例如,当聚合有16个小区,且下行业务量较大时,若需要在该16个小区上调度下行数据,且一个DCI能够调度该16个小区内的数据传输,则终端设备只需要监听1个PDCCH(1个PDCCH承载一个DCI)。相比于一个DCI能够调度一个小区内的数据传输通过一个DCI能够调度该16个小区内的数据传输,可以降低PDCCH的监听复杂度,从而减小终端设备在监听PDCCH上花费大量的功耗,即降低PDCCH的监听复杂度以节省功耗。For example, when there are 16 cells aggregated and the downlink traffic volume is large, if downlink data needs to be scheduled on the 16 cells, and a DCI can schedule data transmission in the 16 cells, the terminal device only needs to monitor 1 PDCCH (one PDCCH bears one DCI). Compared with one DCI that can schedule data transmission in one cell, one DCI can schedule data transmission in 16 cells, which can reduce the complexity of PDCCH monitoring, thereby reducing the power consumption of terminal equipment in monitoring PDCCH. That is, the monitoring complexity of the PDCCH is reduced to save power consumption.
具体实现时,在M(M为大于1的整数)个小区中存在支持多载波调度的被调度小区的情况下,本申请实施例可以通过协议规定、预配置或者网络配置的方式,确定终端设备在时间单元内对于M个小区中的被调度小区的PDCCH候选的最大个数限制和/或非重叠CCE的最大个数限制,使得终端设备可以根据PDCCH候选的最大个数限制和/或非重叠CCE的最大个数限制进行PDCCH的监听,以便有利于降低终端设备监听PDCCH的复杂度以节省功耗的可能性。During specific implementation, when there are scheduled cells that support multi-carrier scheduling among M cells (M is an integer greater than 1), the embodiment of the present application can determine the terminal device Limit the maximum number of PDCCH candidates and/or limit the maximum number of non-overlapping CCEs for the scheduled cell in the M cells in a time unit, so that the terminal device can limit and/or non-overlap according to the maximum number of PDCCH candidates The maximum number of CCEs limits the monitoring of the PDCCH, so as to help reduce the complexity of the terminal equipment monitoring the PDCCH to save the possibility of power consumption.
另外,由于本申请实施例引入了多载波调度,使得一个被调度小区可能仅支持多载波调度,可能同时支持多载波调度和自载波调度,可能同时支持多载波调度和跨载波调度,因此当支持多载波调度时,
本申请实施例的PDCCH候选的最大个数限制和/或非重叠CCE的最大个数限制,需要按照被调度小区被调度的调度小区的个数和被调度小区所支持的调度类型进行确定(或划分)。其中,被调度小区所支持的调度类型包括:被调度小区仅支持多载波调度的调度、被调度小区既支持多载波调度的调度又支持自载波调度或跨载波调度。In addition, since the embodiment of the present application introduces multi-carrier scheduling, a scheduled cell may only support multi-carrier scheduling, may support multi-carrier scheduling and self-carrier scheduling at the same time, may support multi-carrier scheduling and cross-carrier scheduling at the same time, so when supporting When multi-carrier scheduling, The limit on the maximum number of PDCCH candidates and/or the limit on the maximum number of non-overlapping CCEs in this embodiment of the present application needs to be determined according to the number of scheduling cells scheduled by the scheduled cell and the scheduling type supported by the scheduling cell (or division). The scheduling types supported by the scheduled cell include: the scheduled cell only supports multi-carrier scheduling, and the scheduled cell supports both multi-carrier scheduling and self-carrier scheduling or cross-carrier scheduling.
为了实现上述的技术方案,下面对可能涉及的其他内容、概念和含义做进一步解释说明。In order to realize the above-mentioned technical solution, other contents, concepts and meanings that may be involved will be further explained below.
(1)多载波调度(1) Multi-carrier scheduling
在本申请实施例中,多载波调度,可以表示为,一个小区上发送的PDCCH所承载的DCI可以调度多个载波(多个CC或多个小区)内的数据传输。然而,在跨载波调度和自载波调度中,一个小区上发送的PDCCH所承载的DCI只能调度一个载波(或者CC)内的数据传输。In the embodiment of the present application, the multi-carrier scheduling can be expressed as that the DCI carried by the PDCCH sent on one cell can schedule data transmission in multiple carriers (multiple CCs or multiple cells). However, in cross-carrier scheduling and self-carrier scheduling, the DCI carried by the PDCCH sent on one cell can only schedule data transmission in one carrier (or CC).
也就是说,多载波调度是针对一个DCI调度多个载波(或者CC)内的数据传输的情况,而跨载波调度和自载波调度是针对一个DCI调度一个载波(或者CC)内的数据传输的情况。That is to say, multi-carrier scheduling is for one DCI to schedule data transmission in multiple carriers (or CCs), while cross-carrier scheduling and self-carrier scheduling are for one DCI to schedule data transmission in one carrier (or CC) Condition.
需要说明的是,一个小区多载波调度另一些小区,则该另一些小区可以说是支持多载波调度。It should be noted that if one cell schedules other cells with multiple carriers, then the other cells can be said to support multi-carrier scheduling.
例如,小区0(CC0)可以多载波调度小区1(CC1)和小区2(CC2),则小区1(CC1)和小区2(CC2)可以支持多载波调度。For example, cell 0 (CC0) can schedule multiple carriers for cell 1 (CC1) and cell 2 (CC2), then cell 1 (CC1) and cell 2 (CC2) can support multi-carrier scheduling.
另外,结合上述“3、载波聚合”中的内容,在本申请实例中,一个小区可以支持多载波调度,可以同时支持多载波调度和自载波调度,可以同时支持多载波调度和跨载波调度。In addition, combined with the content in "3. Carrier Aggregation" above, in the example of this application, a cell can support multi-carrier scheduling, can support multi-carrier scheduling and self-carrier scheduling, and can support multi-carrier scheduling and cross-carrier scheduling at the same time.
同理,一个载波(或一个CC)可以支持多载波调度,可以同时支持多载波调度和自载波调度,可以同时支持多载波调度和跨载波调度。Similarly, one carrier (or one CC) can support multi-carrier scheduling, can support multi-carrier scheduling and self-carrier scheduling, and can support multi-carrier scheduling and cross-carrier scheduling at the same time.
(2)M个小区、调度小区和被调度小区(2) M cells, scheduling cells and scheduled cells
结合上述“3、载波聚合”中的内容,本申请实施例可以将一个载波(或一个CC)称为或看作一个小区,而支持载波聚合的终端设备可以同时在多个小区内收发数据。Combining the content in "3. Carrier Aggregation" above, in the embodiment of the present application, one carrier (or one CC) can be called or regarded as a cell, and a terminal device supporting carrier aggregation can send and receive data in multiple cells at the same time.
基于此,在本申请实施例中,M个小区可以为载波聚合下的小区。也就是说,终端设备可以载波聚合有M个小区或M个载波。其中,该M个小区中的每个小区对应一个载波(或一个CC)。Based on this, in the embodiment of the present application, the M cells may be cells under carrier aggregation. That is to say, the terminal device may have M cells or M carriers in carrier aggregation. Wherein, each of the M cells corresponds to a carrier (or a CC).
由于本申请实施例引入了多载波调度,因此在该M个小区中存在支持多载波调度的小区。也就是说,在该M个小区中存在有小区支持被其他小区多载波调度。Since the embodiment of the present application introduces multi-carrier scheduling, cells supporting multi-carrier scheduling exist among the M cells. That is to say, among the M cells, some cells support multi-carrier scheduling by other cells.
另外,在该M个小区中,若一个小区可以多载波调度另一个小区,则该一个小区可以称为或看作“调度小区”,而该另一个小区称为或看作“被调度小区”。也就是说,被调度小区支持多载波调度。In addition, among the M cells, if one cell can schedule another cell with multiple carriers, the one cell can be called or regarded as a "scheduling cell", and the other cell can be called or regarded as a "scheduled cell" . That is to say, the scheduled cell supports multi-carrier scheduling.
例如,小区0(CC0)多载波调度小区1(CC1),则小区0(CC0)为调度小区,小区1(CC1)为被调度小区。For example, cell 0 (CC0) multi-carrier schedules cell 1 (CC1), then cell 0 (CC0) is the scheduling cell, and cell 1 (CC1) is the scheduled cell.
需要说明的是,调度小区,也可以称为,多载波调度的调度小区、多载波调度的小区等,对此不作具体限制。It should be noted that the scheduling cell may also be referred to as a multi-carrier scheduling scheduling cell, a multi-carrier scheduling cell, etc., and there is no specific limitation on this.
被调度小区,也可以称为,多载波调度的被调度小区、被多载波调度的小区等,对此不作具体限制。The scheduled cell may also be referred to as a scheduled cell for multi-carrier scheduling, a cell for multi-carrier scheduling, etc., which is not specifically limited.
(3)被调度小区被N(N为大于或等于1的整数)个调度小区调度(3) The scheduled cell is scheduled by N (N is an integer greater than or equal to 1) scheduling cells
在本申请实施例中,一个被调度小区,可以被一个(即N等于1)调度小区调度,也可以被多个(即N大于1)调度小区调度。In the embodiment of the present application, a scheduled cell may be scheduled by one scheduling cell (that is, N is equal to 1), or may be scheduled by multiple scheduling cells (that is, N is greater than 1).
例如,若小区0(CC0)多载波调度小区1(CC1)和小区2(CC2),且小区3(CC3)多载波调
度小区1(CC1),则小区1(CC1)可以被小区0(CC0)和小区3(CC3)调度,而小区2(CC2)仅被小区0(CC0)调度。For example, if cell 0 (CC0) multi-carrier schedules cell 1 (CC1) and cell 2 (CC2), and cell 3 (CC3) multi-carrier Cell 1 (CC1), then Cell 1 (CC1) can be scheduled by Cell 0 (CC0) and Cell 3 (CC3), while Cell 2 (CC2) is only scheduled by Cell 0 (CC0).
(4)被调度小区支持自载波调度或跨载波调度(4) The scheduled cell supports self-carrier scheduling or cross-carrier scheduling
在本申请实施例中,一个被调度小区,可以仅支持多载波调度,可以同时支持多载波调度和自载波调度(既支持多载波调度,又支持自载波调度),可以同时支持多载波调度和跨载波调度(既支持多载波调度,又支持跨载波调度)。In the embodiment of this application, a scheduled cell can only support multi-carrier scheduling, can support multi-carrier scheduling and self-carrier scheduling (supports both multi-carrier scheduling and self-carrier scheduling), and can support multi-carrier scheduling and self-carrier scheduling Cross-carrier scheduling (supports both multi-carrier scheduling and cross-carrier scheduling).
例如,如图2所示,载波聚合的小区包括小区0(CC0)~小区4(CC4)。其中,小区0(CC0)上一个DCI可以多载波调度小区1(CC1)、小区2(CC2)、小区3(CC3)和小区4(CC4)。因此,小区1(CC1)~小区4(CC4)仅只能被小区0(CC0)调度,以及小区1(CC1)~小区4(CC4)仅支持多载波调度。For example, as shown in FIG. 2 , the cells of carrier aggregation include cell 0 (CC0) to cell 4 (CC4). Wherein, one DCI on cell 0 (CC0) can schedule multi-carrier cell 1 (CC1), cell 2 (CC2), cell 3 (CC3) and cell 4 (CC4). Therefore, cell 1 (CC1)-cell 4 (CC4) can only be scheduled by cell 0 (CC0), and cell 1 (CC1)-cell 4 (CC4) only support multi-carrier scheduling.
又例如,如图3所示,载波聚合的小区包括小区0(CC0)~小区4(CC4)。其中,小区0(CC0)上一个DCI可以多载波调度小区1(CC1)、小区2(CC2)、小区3(CC3)和小区4(CC4)。小区1(CC1)可以自载波调度,小区2(CC2)可以被小区1(CC1)跨载波调度。因此,小区1(CC1)同时支持多载波调度和自载波调度,且小区1(CC1)不支持跨载波调度;小区2(CC2)同时支持多载波调度和跨载波调度,且小区2(CC2)不支持跨载波调度;小区3(CC3)和小区4(CC4)仅支持多载波调度。For another example, as shown in FIG. 3 , the cells of carrier aggregation include cell 0 (CC0) to cell 4 (CC4). Wherein, one DCI on cell 0 (CC0) can schedule multi-carrier cell 1 (CC1), cell 2 (CC2), cell 3 (CC3) and cell 4 (CC4). Cell 1 (CC1) can be self-carrier-scheduled, and cell 2 (CC2) can be cross-carrier-scheduled by Cell 1 (CC1). Therefore, cell 1 (CC1) supports both multi-carrier scheduling and self-carrier scheduling, and cell 1 (CC1) does not support cross-carrier scheduling; cell 2 (CC2) supports both multi-carrier scheduling and cross-carrier scheduling, and cell 2 (CC2) Cross-carrier scheduling is not supported; cell 3 (CC3) and cell 4 (CC4) only support multi-carrier scheduling.
又例如,如图4所示,载波聚合的小区包括小区0(CC0)~小区4(CC4)。其中,小区0(CC0)上一个DCI可以多载波调度小区1(CC1)、小区2(CC2)、小区3(CC3)和小区4(CC4),且小区5(CC5)上一个DCI可以多载波调度小区1(CC1)、小区2(CC2)和小区3(CC3)。小区1(CC1)可以自载波调度,小区2(CC2)可以被小区1(CC1)跨载波调度。因此,小区1(CC1)同时支持多载波调度和自载波调度,小区2(CC2)同时支持多载波调度和跨载波调度,小区3(CC3)和小区4(CC4)仅支持多载波调度。For another example, as shown in FIG. 4 , the cells of carrier aggregation include cell 0 (CC0) to cell 4 (CC4). Among them, one DCI on cell 0 (CC0) can multi-carrier schedule cell 1 (CC1), cell 2 (CC2), cell 3 (CC3) and cell 4 (CC4), and one DCI on cell 5 (CC5) can multi-carrier Cell 1 (CC1), cell 2 (CC2) and cell 3 (CC3) are scheduled. Cell 1 (CC1) can be self-carrier-scheduled, and cell 2 (CC2) can be cross-carrier-scheduled by Cell 1 (CC1). Therefore, cell 1 (CC1) supports both multi-carrier scheduling and self-carrier scheduling, cell 2 (CC2) supports both multi-carrier scheduling and cross-carrier scheduling, and cell 3 (CC3) and cell 4 (CC4) only support multi-carrier scheduling.
(5)第一信息(5) First information

另外,第一信息也可以采用其他术语描述,如配置信息或指示信息等,只有具有相同的含义/功能/解释/概念等,都在本申请实施例所要求保护的范围内。In addition, other terms may also be used to describe the first information, such as configuration information or indication information, etc., as long as they have the same meaning/function/interpretation/concept, etc., they are all within the scope of protection claimed in the embodiments of this application.
在一些可能的实现中,第一信息可以是在小区搜索、小区重选、上下行同步、小区接入、小区驻留、初始接入或上下行资源调度等过程中发送或获取的。In some possible implementations, the first information may be sent or acquired during cell search, cell reselection, uplink and downlink synchronization, cell access, cell camping, initial access, or uplink and downlink resource scheduling.
在一些可能的实现中,第一信息可以由系统信息(SI)、高层信令(如RRC信令)、终端设备专属信令等携带。In some possible implementations, the first information may be carried by system information (SI), high-level signaling (such as RRC signaling), terminal equipment-specific signaling, and the like.
在一些可能的实现中,第一信息可以包括以下至少之一项:调度小区的子载波间隔、被调度小区的子载波间隔、终端设备上报的PDCCH监听能力、小区个数M、自载波调度因子或跨载波调度因子、多载波调度因子。

需要说明的是,调度小区的子载波间隔、被调度小区的子载波间隔、终端设备上报的PDCCH监听能力、小区个数M、自载波调度因子或跨载波调度因子、多载波调度因子,将分别下文说明。It should be noted that the subcarrier spacing of the scheduling cell, the subcarrier spacing of the scheduled cell, the PDCCH monitoring capability reported by the terminal equipment, the number of cells M, the self-carrier scheduling factor or cross-carrier scheduling factor, and the multi-carrier scheduling factor will be respectively Explained below.
(6)时间单元(6) Time unit
在本申请实施例中,时间单元,可以理解为,在时域上的通信粒度。例如,终端设备和网络设备在时域上以时间单元为粒度/单位进行通信。In this embodiment of the present application, a time unit may be understood as a communication granularity in the time domain. For example, a terminal device and a network device communicate with a granularity/unit of a time unit in the time domain.
在一些可能的实现中,时间单元可以时隙、(X,Y)组合的间隔(span)、(XS,YS)组合的多时隙中的之一项。In some possible implementations, the time unit may be one of a time slot, an interval (span) of (X, Y) combination, or a multi-slot of (X S , Y S ) combination.
(7)支持多载波调度下的PDCCH候选的最大个数限制和非重叠CCE的最大个数限制(7) Support the maximum number of PDCCH candidates and the maximum number of non-overlapping CCEs under multi-carrier scheduling
需要说明的是,在上述“4)PDCCH候选的最大个数限制和非重叠CCE的最大个数限制”中,本申请实施例只针对小区仅支持自载波调度或跨载波调度下的PDCCH候选的最大个数限制和非重叠CCE的最大个数限制。然而,在小区支持多载波调度下的PDCCH候选的最大个数限制和非重叠CCE的最大个数限制,还需要进一步研究。It should be noted that, in the above "4) Limitation on the maximum number of PDCCH candidates and the maximum number of non-overlapping CCEs", the embodiment of the present application only supports PDCCH candidates under self-carrier scheduling or cross-carrier scheduling for the cell. The maximum number limit and the maximum number limit of non-overlapping CCEs. However, the maximum number of PDCCH candidates and the maximum number of non-overlapping CCEs under the condition that the cell supports multi-carrier scheduling still need further research.
由于本申请实施例需要按照被调度小区被调度的调度小区的个数(如N)和被调度小区所支持的调度类型对PDCCH候选的最大个数限制和/或非重叠CCE的最大个数限制进行确定(或划分),而N的取值以及被调度小区所支持的调度类型均存在不同情况,因此,下面本申请实施例将分不同情形进行说明。Since the embodiment of this application needs to limit the maximum number of PDCCH candidates and/or the maximum number of non-overlapping CCEs according to the number of scheduling cells scheduled by the scheduled cell (such as N) and the scheduling type supported by the scheduling cell The determination (or division) is performed, and the value of N and the scheduling type supported by the scheduled cell are different. Therefore, the following embodiments of the present application will be described in different situations.
情形1:Scenario 1:
M个小区中存在一个调度小区调度多个被调度小区,且被调度小区仅支持多载波调度。Among the M cells, one scheduling cell schedules multiple scheduled cells, and the scheduled cell only supports multi-carrier scheduling.
也就是说,一个被调度小区被一个(即N=1)调度小区调度,且该被调度小区仅支持多载波调度。That is, one scheduled cell is scheduled by one (that is, N=1) scheduling cell, and the scheduled cell only supports multi-carrier scheduling.
因此,在“情形1”中,本申请实施例可以不对终端设备在时间单元内对于被调度小区的PDCCH候选的最大个数限制和/或非重叠CCE的最大个数限制进行确定(或划分),并可以采用上述“情形一”、“情形二”、“情形三”、“情形四”和“情形五”中的方式。其中,时间单元为调度小区的激活DL BWP上的时隙/(X,Y)组合的span/(XS,YS)组合的多时隙,SCS配置μ为调度小区对应的子载波间隔。Therefore, in "case 1", the embodiment of the present application may not determine (or divide) the maximum number of PDCCH candidates and/or the maximum number of non-overlapping CCEs for the terminal device within a time unit , and the methods in the above "case 1", "case 2", "case 3", "case 4" and "case 5" can be adopted. Wherein, the time unit is the time slot on the activated DL BWP of the scheduling cell/the span of the (X,Y) combination/the multi-slot of the (X S , Y S ) combination, and the SCS configuration μ is the subcarrier interval corresponding to the scheduling cell.
例如,在图2中,小区1(CC1)被小区0(CC0)多载波调度,且小区1(CC1)仅支持多载波调度。因此,本申请实施例可以配置终端设备在小区1(CC1)的激活DL BWP上的时隙/(X,Y)组合的span/(XS,YS)组合的多时隙内的PDCCH候选的最大个数和/或非重叠CCE的最大个数。For example, in FIG. 2, cell 1 (CC1) is multi-carrier scheduled by cell 0 (CC0), and cell 1 (CC1) only supports multi-carrier scheduling. Therefore, the embodiment of the present application can configure the PDCCH candidates in the multi-slot of the time slot/(X,Y) combination span/(X S ,Y S ) combination of the terminal device on the active DL BWP of cell 1 (CC1) The maximum number and/or the maximum number of non-overlapping CCEs.
情形2:Scenario 2:
M个小区中存在多个调度小区调度多个被调度小区,且该多个被调度小区仅支持多载波调度。There are multiple scheduling cells scheduling multiple scheduled cells among the M cells, and the multiple scheduled cells only support multi-carrier scheduling.
也就是说,一个被调度小区被N(1<N<M)个调度小区调度,且该被调度小区仅支持多载波调度。That is to say, a scheduled cell is scheduled by N (1<N<M) scheduling cells, and the scheduled cell only supports multi-carrier scheduling.
因此,在“情形2”中,本申请实施例可以对终端设备在时间单元内对于被调度小区的PDCCH候选的最大个数限制和/或非重叠CCE的最大个数限制进行确定(或划分)。其中,时间单元为调度小区的激活DL BWP上的时隙/(X,Y)组合的span/(XS,YS)组合的多时隙,SCS配置μ为调度小区对应的子载波间隔。Therefore, in "Case 2", the embodiment of the present application can determine (or divide) the maximum number of PDCCH candidates and/or the maximum number of non-overlapping CCEs of the terminal device within a time unit for the scheduled cell . Wherein, the time unit is the time slot on the activated DL BWP of the scheduling cell/the span of the (X,Y) combination/the multi-slot of the (X S , Y S ) combination, and the SCS configuration μ is the subcarrier interval corresponding to the scheduling cell.
在“情形2”中,本申请实施例可以通过高层信令配置N(1<N<M)个多载波调度因子,即bi,i={1,2,...,N},并通过该N个多载波调度因子将PDCCH候选的最大个数限制确定(或
划分)成N个支持多载波调度的部分,每个部分需要乘以相应的一个多载波调度因子。In "case 2", the embodiment of the present application can configure N (1<N<M) multi-carrier scheduling factors through high-level signaling, that is, b i , i={1,2,...,N}, And determine the maximum number of PDCCH candidates by the N multi-carrier scheduling factors (or Divide) into N parts that support multi-carrier scheduling, and each part needs to be multiplied by a corresponding multi-carrier scheduling factor.
同理,在“情形2”中,本申请实施例可以通过高层信令配置N个多载波调度因子,即bi,i={1,2,...,N},并通过该N个多载波调度因子将非重叠CCE的最大个数限制确定(或划分)成N个部分,每个部分需要乘以相应的一个多载波调度因子。Similarly, in "Case 2", the embodiment of the present application can configure N multi-carrier scheduling factors through high-layer signaling, that is, b i , i={1,2,...,N}, And the maximum number limit of non-overlapping CCEs is determined (or divided) into N parts through the N multi-carrier scheduling factors, and each part needs to be multiplied by a corresponding multi-carrier scheduling factor.
另外,一个多载波调度因子,可以理解为,一个加权因子,目的是将PDCCH候选的最大个数限制或者非重叠CCE的最大个数限制确定(或划分)成支持多载波调度的部分。其中,多载波调度因子,也可以采用其他术语描述,对此不作具体限制。In addition, a multi-carrier scheduling factor can be understood as a weighting factor, the purpose of which is to determine (or divide) the maximum number of PDCCH candidates or the maximum number of non-overlapping CCEs into parts that support multi-carrier scheduling. Wherein, the multi-carrier scheduling factor may also be described in other terms, which is not specifically limited.
例如,在图4中,小区3(CC3)被小区0(CC0)和小区5(CC5)多载波调度,且小区3(CC3)仅支持多载波调度。因此,本申请实施例可以通过高层信令为小区3配置2个多载波调度因子,即CC0的多载波调度因子、CC5的多载波调度因子,并通过该2个多载波调度因子将对于小区3的PDCCH候选的最大个数限制或者非重叠CCE的最大个数限制确定(或划分)成2个支持多载波调度的部分。For example, in FIG. 4, cell 3 (CC3) is multi-carrier scheduled by cell 0 (CC0) and cell 5 (CC5), and cell 3 (CC3) only supports multi-carrier scheduling. Therefore, in this embodiment of the present application, two multi-carrier scheduling factors can be configured for cell 3 through high-level signaling, that is, the multi-carrier scheduling factor of CC0 and the multi-carrier scheduling factor of CC5, and the two multi-carrier scheduling factors will be used for cell 3 The maximum number of PDCCH candidates or the maximum number of non-overlapping CCEs is determined (or divided) into two parts that support multi-carrier scheduling.
情形3:Case 3:
M个小区中存在一个调度小区调度多个被调度小区,且该多个被调度小区中存在全部或部分的被调度小区既支持多载波调度,又支持自载波调度或跨载波调度。One scheduling cell among the M cells schedules multiple scheduled cells, and all or part of the scheduled cells among the multiple scheduled cells support multi-carrier scheduling, self-carrier scheduling or cross-carrier scheduling.
也就是说,一个被调度小区被一个(即N=1)调度小区调度,且该被调度小区既支持多载波调度,又支持自载波调度或跨载波调度。That is to say, one scheduled cell is scheduled by one (that is, N=1) scheduling cell, and the scheduled cell not only supports multi-carrier scheduling, but also supports self-carrier scheduling or cross-carrier scheduling.
因此,在“情形3”中,本申请实施例可以对终端设备在时间单元内对于被调度小区的PDCCH候选的最大个数限制和非重叠CCE的最大个数限制进行确定(或划分)。Therefore, in "Case 3", the embodiment of the present application may determine (or divide) the maximum number of PDCCH candidates and the maximum number of non-overlapping CCEs of the terminal device for the scheduled cell within a time unit.
●若被调度小区支持多载波调度和自载波调度,则时间单元分为:●If the scheduled cell supports multi-carrier scheduling and self-carrier scheduling, the time unit is divided into:
调度小区的激活DL BWP上的时隙/(X,Y)组合的span/(XS,YS)组合的多时隙;和,Slot/(X,Y) combined span/(X S , Y S ) combined multi-slot on the active DL BWP of the scheduling cell; and,
该被调度小区的激活DL BWP上的时隙/(X,Y)组合的span/(XS,YS)组合的多时隙。The time slot on the activated DL BWP of the scheduled cell/span of (X, Y) combination/multiple time slots of (X S , Y S ) combination.
●若被调度小区支持多载波调度和自载波调度,则SCS配置μ分为:●If the scheduled cell supports multi-carrier scheduling and self-carrier scheduling, the SCS configuration μ is divided into:
调度小区对应的子载波间隔,即μMS;和,The subcarrier spacing corresponding to the scheduling cell, i.e. μ MS ; and,
该被调度小区对应的子载波间隔,即μMSd。The subcarrier spacing corresponding to the scheduled cell, that is μ MSd .
例如,若小区0多载波调度小区1和小区2,且小区1支持子载波调度,则μMS为小区0的子载波间隔,μMSd为小区1的子载波间隔。For example, if cell 0 multi-carrier schedules cell 1 and cell 2, and cell 1 supports subcarrier scheduling, μ MS is the subcarrier spacing of cell 0, and μ MSd is the subcarrier spacing of cell 1.
●若被调度小区支持多载波调度和跨载波调度,则时间单元分为:●If the scheduled cell supports multi-carrier scheduling and cross-carrier scheduling, the time unit is divided into:
调度小区的激活DL BWP上的时隙/(X,Y)组合的span/(XS,YS)组合的多时隙;和,Slot/(X,Y) combined span/(X S , Y S ) combined multi-slot on the active DL BWP of the scheduling cell; and,
跨载波调度该被调度小区的小区的激活DL BWP上的时隙/(X,Y)组合的span/(XS,YS)组合的多时隙。Cross-carrier scheduling of the activated DL BWP of the cell of the scheduled cell/span of (X, Y) combination/multiple time slots of (X S , Y S ) combination.
例如,若小区0多载波调度小区1和小区2,且小区1跨载波调度小区2,则小区1为跨载波调度小区2的小区。For example, if Cell 0 schedules Cell 1 and Cell 2 on multiple carriers, and Cell 1 schedules Cell 2 across carriers, then Cell 1 is the cell that schedules Cell 2 across carriers.
●若被调度小区支持多载波调度和跨载波调度,则SCS配置μ分为:●If the scheduled cell supports multi-carrier scheduling and cross-carrier scheduling, the SCS configuration μ is divided into:
调度小区对应的子载波间隔,即μMS;和,The subcarrier spacing corresponding to the scheduling cell, i.e. μ MS ; and,
跨载波调度该被调度小区的小区对应的子载波间隔,即μMSd。The subcarrier spacing corresponding to the cell of the scheduled cell is cross-carrier scheduled, that is, μ MSd .
例如,若小区0多载波调度小区1和小区2,且小区1跨载波调度小区2,则小区1为跨载波调度
小区2的小区,μMS为小区0的子载波间隔,μMSd为小区1的子载波间隔。For example, if Cell 0 schedules Cell 1 and Cell 2 with multiple carriers, and Cell 1 schedules Cell 2 across carriers, then Cell 1 is cross-carrier scheduling For the cell of cell 2, μ MS is the subcarrier spacing of cell 0, and μ MSd is the subcarrier spacing of cell 1.
在“情形3”中,本申请实施例可以通过高层信令配置一个自载波调度因子(或一个跨载波调度因子),即a,以及一个多载波调度因子,即b,且a+b≤1。In "Case 3", the embodiment of the present application can configure a self-carrier scheduling factor (or a cross-carrier scheduling factor), namely a, and a multi-carrier scheduling factor, namely b, through high-level signaling, and a+b≤1 .
然后,通过a和b将PDCCH候选的最大个数限制确定(或划分)成2个部分,即一个支持自载波调度(或跨载波调度)的部分需要乘以a,另一个支持多载波调度的部分需要乘以b。Then, determine (or divide) the maximum number of PDCCH candidates into two parts through a and b, that is, a part that supports self-carrier scheduling (or cross-carrier scheduling) needs to be multiplied by a, and another part that supports multi-carrier scheduling Part needs to be multiplied by b.
也就是说,若被调度小区同时支持多载波调度和自载波调度,则通过高层信令配置一个自载波调度因子和一个多载波调度因子。若被调度小区同时支持多载波调度和跨载波调度,则通过高层信令配置一个跨载波调度因子和一个多载波调度因子。That is to say, if the scheduled cell supports both multi-carrier scheduling and self-carrier scheduling, a self-carrier scheduling factor and a multi-carrier scheduling factor are configured through high-layer signaling. If the scheduled cell supports both multi-carrier scheduling and cross-carrier scheduling, a cross-carrier scheduling factor and a multi-carrier scheduling factor are configured through high-layer signaling.
需要说明的是,一个自载波调度因子,可以理解为,一个加权因子,目的是将PDCCH候选的最大个数限制或者非重叠CCE的最大个数限制确定(或划分)成支持自载波调度的部分。其中,自载波调度因子,也可以采用其他术语描述,对此不作具体限制。It should be noted that a self-carrier scheduling factor can be understood as a weighting factor, the purpose of which is to determine (or divide) the maximum number limit of PDCCH candidates or the maximum number limit of non-overlapping CCEs into parts that support self-carrier scheduling . Wherein, the self-carrier scheduling factor may also be described in other terms, which is not specifically limited.
一个跨载波调度因子,可以理解为,一个加权因子,目的是将PDCCH候选的最大个数限制或者非重叠CCE的最大个数限制确定(或划分)成支持跨载波调度的部分。其中,跨载波调度因子,也可以采用其他术语描述,对此不作具体限制。A cross-carrier scheduling factor can be understood as a weighting factor for determining (or dividing) the maximum number of PDCCH candidates or the maximum number of non-overlapping CCEs into parts that support cross-carrier scheduling. Wherein, the cross-carrier scheduling factor may also be described in other terms, which is not specifically limited.
例如,在图3中,小区1(CC1)被小区0(CC0)多载波调度,且小区1(CC1)既支持多载波调度,又支持自载波调度。因此,本申请实施例可以通过高层信令为小区1(CC1)配置1个多载波调度因子和1个自载波调度因子,并以此将对于小区1(CC1)的PDCCH候选的最大个数限制或者非重叠CCE的最大个数限制确定(或划分)成支持多载波调度的部分和支持自载波调度的部分。For example, in FIG. 3 , cell 1 (CC1) is multi-carrier scheduled by cell 0 (CC0), and cell 1 (CC1) supports both multi-carrier scheduling and self-carrier scheduling. Therefore, in this embodiment of the present application, one multi-carrier scheduling factor and one self-carrier scheduling factor can be configured for cell 1 (CC1) through high-layer signaling, and the maximum number of PDCCH candidates for cell 1 (CC1) can be limited accordingly. Or the maximum number of non-overlapping CCEs is determined (or divided) into a part supporting multi-carrier scheduling and a part supporting self-carrier scheduling.
又例如,在图3中,小区2(CC1)被小区0(CC0)多载波调度,且小区2(CC2)既支持多载波调度,又支持跨载波调度。因此,本申请实施例可以通过高层信令为小区2(CC2)配置1个多载波调度因子和1个跨载波调度因子,并以此将对于小区2(CC2)的PDCCH候选的最大个数限制或者非重叠CCE的最大个数限制确定(或划分)成支持多载波调度的部分和支持跨载波调度的部分。For another example, in FIG. 3 , cell 2 (CC1) is multi-carrier scheduled by cell 0 (CC0), and cell 2 (CC2) supports both multi-carrier scheduling and cross-carrier scheduling. Therefore, in this embodiment of the present application, one multi-carrier scheduling factor and one cross-carrier scheduling factor can be configured for cell 2 (CC2) through high-layer signaling, and the maximum number of PDCCH candidates for cell 2 (CC2) can be limited accordingly. Or the maximum number of non-overlapping CCEs is determined (or divided) into a part supporting multi-carrier scheduling and a part supporting cross-carrier scheduling.
情形4:Scenario 4:
M个小区中存在多个调度小区调度多个被调度小区,且该多个被调度小区中存在全部或部分的被调度小区既支持多载波调度,又支持自载波调度或跨载波调度。There are multiple scheduling cells in the M cells to schedule multiple scheduled cells, and all or part of the scheduled cells among the multiple scheduled cells support multi-carrier scheduling, self-carrier scheduling or cross-carrier scheduling.
也就是说,一个被调度小区被N(1<N<M)个调度小区调度,且该被调度小区既支持多载波调度,又支持自载波调度或跨载波调度。That is to say, a scheduled cell is scheduled by N (1<N<M) scheduling cells, and the scheduled cell not only supports multi-carrier scheduling, but also supports self-carrier scheduling or cross-carrier scheduling.
因此,在“情形4”中,本申请实施例可以对终端设备在时间单元内对于被调度小区的PDCCH候选的最大个数限制和非重叠CCE的最大个数限制进行确定(或划分)。Therefore, in "Case 4", the embodiment of the present application may determine (or divide) the maximum number of PDCCH candidates and the maximum number of non-overlapping CCEs of the terminal device for the scheduled cell within a time unit.

②非重叠CCE的最大个数限制②The maximum number limit of non-overlapping CCE
若一个被调度小区被一个调度小区调度,且该被调度小区既支持多载波调度,又支持自载波调度或跨载波调度,则非重叠CCE的最大个数限制可以包括一个第二类非重叠CCE的最大个数限制和一个(N=1)第一类非重叠CCE的最大个数限制。其中,本申请实施例可以存在如下两种方式:If a scheduled cell is scheduled by a scheduling cell, and the scheduled cell supports both multi-carrier scheduling, self-carrier scheduling or cross-carrier scheduling, the maximum number of non-overlapping CCEs may include a second type of non-overlapping CCE and the maximum number of one (N=1) first-type non-overlapping CCEs. Among them, the embodiment of this application may have the following two modes:

需要说明的是,本申请实施例的第三非重叠CCE的最大个数,与上述第一非重叠CCE的最大个数的区别仅在于,用被调度小区的子载波间隔μMSd替换调度小区的子载波间隔μ。其中,若被调度小区支持自载波调度,则μMSd为该被调度小区对应的子载波间隔;若被调度小区支持跨载波调度,则μMSd为跨载波调度该被调度小区的小区对应的子载波间隔。It should be noted that the difference between the maximum number of the third non-overlapping CCEs in the embodiment of the present application and the maximum number of the first non-overlapping CCEs is that the subcarrier spacing μ MSd of the scheduled cell is used to replace the subcarrier spacing μ MSd of the scheduling cell.

6、一种PDCCH监听方法的示例性说明6. An exemplary description of a PDCCH monitoring method
综上所述,下面以网络设备与终端设备之间的交互为例,对本申请实施例的一种PDCCH监听方法进行示例介绍。其中,网络设备也可以为芯片/芯片模组/装置等,终端设备也可以为芯片/芯片模组/装置等,对此不作具体限制。To sum up, the following uses the interaction between a network device and a terminal device as an example to introduce a method for monitoring a PDCCH according to an embodiment of the present application. Wherein, the network device may also be a chip/chip module/device, etc., and the terminal device may also be a chip/chip module/device, etc., which are not specifically limited.
如图5所示,为本申请实施例的一种PDCCH监听方法的流程示意图,具体包括如下步骤:As shown in Figure 5, it is a schematic flow chart of a PDCCH monitoring method according to the embodiment of the present application, which specifically includes the following steps:
S510、网络设备发送第一信息,第一信息用于确定终端设备在时间单元内对于M个小区中的被调度小区的PDCCH候选的最大个数限制或者非重叠CCE的最大个数限制。S510. The network device sends first information, where the first information is used to determine the maximum number of PDCCH candidates or the maximum number of non-overlapping CCEs of the terminal device for scheduled cells in the M cells within a time unit.
其中,被调度小区为支持多载波调度的小区。Wherein, the scheduled cell is a cell supporting multi-carrier scheduling.
其中,多载波调度表示M个小区中的调度小区发送的PDCCH所承载的DCI调度多个被调度小区内的数据传输。Wherein, the multi-carrier scheduling means that the DCI carried by the PDCCH sent by the scheduling cell in the M cells schedules data transmission in multiple scheduled cells.
其中,M为大于1的整数。Wherein, M is an integer greater than 1.
对应的,终端设备获取第一信息。Correspondingly, the terminal device acquires the first information.
需要说明的是,对于“第一信息”、“M个小区”、“多载波调度”、“调度小区”、“被调度小区”等,具体详见上述内容,对此不再赘述。It should be noted that, for "first information", "M cells", "multi-carrier scheduling", "scheduling cell", "scheduled cell", etc., refer to the above content for details, and will not repeat them here.
另外,本申请实施例的M个小区中存在支持多载波调度的被调度小区。其中,支持多载波调度的小区,可以为支持通过第一DCI调度的小区,第一DCI为M个小区中的调度小区上发送的PDCCH所承载的用于调度多个小区的DCI。In addition, among the M cells in the embodiment of the present application, there are scheduled cells that support multi-carrier scheduling. Wherein, the cell supporting multi-carrier scheduling may be a cell supporting scheduling through the first DCI, and the first DCI is the DCI for scheduling multiple cells carried by the PDCCH sent on the scheduling cell among the M cells.
当然,第一DCI也可以采用其他术语描述,对此不作具体限制。Of course, the first DCI may also be described using other terms, which are not specifically limited.
S520、终端设备根据PDCCH候选的最大个数限制和/或非重叠CCE的最大个数限制进行PDCCH监听。S520. The terminal device monitors the PDCCH according to the maximum number of PDCCH candidates and/or the maximum number of non-overlapping CCEs.
可见,本申请实施例引入M个小区中的调度小区发送的PDCCH所承载的DCI调度多个被调度小区内的数据传输,即多载波调度,并通过第一信息确定终端设备在时间单元内对于M个小区中的被调度小区的PDCCH候选的最大个数限制和/或非重叠CCE的最大个数限制,使得终端设备可以根据PDCCH候选的最大个数限制和/或非重叠CCE的最大个数限制进行PDCCH监听,从而有利于实现在支持多载波调度的情况下进行PDCCH监听,并通过多载波调度实现降低PDCCH的监听复杂度以节省功耗的可能性。It can be seen that the embodiment of the present application introduces the DCI carried by the PDCCH sent by the scheduling cell in the M cells to schedule data transmission in multiple scheduled cells, that is, multi-carrier scheduling, and determines the terminal device's response time within the time unit through the first information. Limit the maximum number of PDCCH candidates and/or limit the maximum number of non-overlapping CCEs of the scheduled cell in M cells, so that the terminal device can limit the maximum number of PDCCH candidates and/or the maximum number of non-overlapping CCEs Limiting PDCCH monitoring is beneficial to implement PDCCH monitoring when multi-carrier scheduling is supported, and realize the possibility of reducing PDCCH monitoring complexity and saving power consumption through multi-carrier scheduling.
