Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a physical downlink control channel monitoring method and apparatus, terminal equipment, and network equipment. Background Technology

[0002] In the Carrier Aggregation (CA) scenario, the standard protocol developed by the 3rd Generation Partnership Project (3GPP) stipulates that a cell must either support only self-carrier scheduling or only cross-carrier scheduling.

[0003] Currently, the downlink control information (DCI) carried by the Physical Downlink Control Channel (PDCCH) transmitted on a cell can only schedule data transmission within one carrier (one component carrier (CC) or one cell).

[0004] Since a single DCI can only schedule data transmission within one carrier (or one cell), in carrier aggregation scenarios, especially when there are many aggregated cells and high traffic volume, the terminal device needs to consume a significant amount of power to listen to (or blindly detect) the PDCCH of each cell. For example, when there are 16 aggregated cells and the downlink traffic volume is high, if downlink data needs to be scheduled on these 16 cells, and one DCI can only schedule data transmission within one cell, the terminal device needs to listen to the PDCCH of each cell separately, requiring a total of 16 PDCCHs to be listened to (one PDCCH carries one DCI), resulting in a significant power consumption for the terminal device in listening to the PDCCH. Therefore, further research is needed on how to reduce the complexity of PDCCH listening to save power. Summary of the Invention

[0005] This application provides a physical downlink control channel (PDCCH) monitoring method and apparatus, terminal equipment, and network equipment to reduce the monitoring complexity of the PDCCH and save power consumption.

[0007] Obtain first information, which is used to determine the maximum number of Physical Downlink Control Channel (PDCCH) candidates and / or the maximum number of Non-overlapping Channel Control Elements (CCEs) for the scheduled cells in M ​​cells within a time unit. The scheduled cells are cells that support multi-carrier scheduling. Multi-carrier scheduling means that the Physical Downlink Control Information (DCI) carried by the PDCCH transmitted on the scheduling cell in the M cells schedules data transmission in multiple scheduled cells. M is an integer greater than 1.

[0008] PDCCH listening is performed based on the maximum number of PDCCH candidates and / or the maximum number of non-overlapping CCEs.

The terminal device determines the maximum number of PDCCH candidates and / or the maximum number of non-overlapping CCEs in the scheduled cells in M ​​cells within a time unit through the first information. This allows the terminal device to perform PDCCH listening according to the maximum number of PDCCH candidates and / or the maximum number of non-overlapping CCEs, thereby facilitating PDCCH listening while supporting multi-carrier scheduling and reducing the complexity of PDCCH listening to save power consumption.

Multi-carrier scheduling means that the Physical Downlink Control Information (DCI) carried by the PDCCH sent on the scheduling cell in the M cells schedules data transmission in multiple scheduled cells.

Multi-carrier scheduling means that the Physical Downlink Control Information (DCI) carried by the PDCCH transmitted on the scheduling cells in the M cells schedules the data transmission in multiple scheduled cells. M is an integer greater than 1.

[0014] The monitoring unit is used to monitor the PDCCH according to the maximum number limit of the PDCCH candidates and / or the maximum number limit of the non-overlapping CCEs.

[0015] Fourthly, this application provides a physical downlink control channel monitoring device, comprising:

[0016] A transmitting unit is used to transmit first information, which is used to determine the maximum number of Physical Downlink Control Channel (PDCCH) candidates and / or the maximum number of Non-overlapping Channel Control Elements (CCEs) for the scheduled cells in M ​​cells within a time unit. The scheduled cells are cells that support multi-carrier scheduling. Multi-carrier scheduling means that the Physical Downlink Control Information (DCI) carried by the PDCCH transmitted on the scheduling cell in the M cells schedules data transmission in multiple scheduled cells. M is an integer greater than 1. The maximum number of PDCCH candidates and / or the maximum number of Non-overlapping CCEs are used for PDCCH monitoring.

[0055] In this embodiment, the terminal device may include a device with wireless communication functionality, such as a chip system, a chip, or a chip module. For example, the chip system may include a chip, and may also include other discrete devices.

[0056] 3) Network equipment

[0057] In this embodiment, the network device is a device with transceiver capabilities used for communication with terminal devices. For example, the network device can be responsible for radio resource management (RRM), quality of service (QoS) management, data compression and encryption, and data transmission and reception on the air interface side. The network device can be a base station (BS) in a communication system or a device deployed in a radio access network (RAN) to provide wireless communication functions. Examples include evolved node B (eNB or eNodeB) in an LTE communication system, next-generation evolved node B (ng-eNB) in an NR communication system, next-generation node B (gNB) in an NR communication system, master node (MN) in a dual-connectivity architecture, and secondary node (SN) in a dual-connectivity architecture; no specific limitations are imposed on this.

[0058] In this embodiment of the application, the network device may also be a device in the core network (CN), such as the access and mobility management function (AMF) and user plane function (UPF); it may also be an access point (AP) in a wireless local area network (WLAN), a relay station, a communication device in a future PLMN network, or a communication device in an NTN network.

[0059] In this embodiment of the application, the network device may include means for providing wireless communication functions for terminal devices, such as a chip system, a chip, or a chip module. For example, the chip system may include a chip, or it may include other discrete devices.

[0060] In this embodiment, the network device can communicate with an Internet Protocol (IP) network, such as the Internet, a private IP network, or other data networks.

[0061] In this embodiment, the network device can be a single independent node to implement the functions of the aforementioned base station, or the network device can include two or more independent nodes to implement the functions of the aforementioned base station. For example, the network device includes a centralized unit (CU) and a distributed unit (DU), such as gNB-CU and gNB-DU. Further, in some other embodiments of this application, the network device may also include an active antenna unit (AAU). The CU implements some of the functions of the network device, and the DU implements other functions. For example, the CU is responsible for handling non-real-time protocols and services, implementing the functions of the radio resource control (RRC) layer, service data adaptation protocol (SDAP) layer, and packet data convergence protocol (PDCP) layer. The DU is responsible for handling physical layer protocols and real-time services, implementing the functions of the radio link control (RLC) layer, medium access control (MAC) layer, and physical (PHY) layer. Additionally, the AAU can implement some physical layer processing functions, radio frequency processing, and related functions of the active antenna. Since RRC layer information ultimately becomes PHY layer information, or is derived from PHY layer information, in this network deployment, higher-layer signaling (such as RRC signaling) can be considered to be sent by the DU, or jointly by the DU and AAU. It is understood that network devices can include at least one of CU, DU, and AAU. Furthermore, the CU can be classified as a network device in the RAN, or it can be classified as a network device in the core network; no specific limitations are imposed on this.

[0062] In this embodiment, the network device may have mobility characteristics; for example, the network device may be a mobile device. Optionally, the network device may be a satellite or a balloon station. For example, the satellite may be a low Earth orbit (LEO) satellite, a medium Earth orbit (MEO) satellite, a geostationary orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, etc. Optionally, the network device may also be a base station located on land, water, or other similar locations.

[0063] In this embodiment, the network device can provide services to a cell, and the terminal devices in the cell can communicate with the network device through transmission resources (such as spectrum resources). The cell can be a macro cell, small cell, metro cell, micro cell, pico cell, or femto cell, etc.

[0064] 4) Exemplary Description

[0065] Based on the above description, the communication system of this application embodiment will be described below as an example.

[0066] For example, such as Figure 1 As shown, the communication system 10 may include a terminal device 110 and a network device 120, wherein the network device 120 may be a device that communicates with the terminal device 110. Simultaneously, the network device 120 may provide communication coverage for a specific geographical area and may communicate with the terminal 110 located within that coverage area.

[0067] The communication system 10 may also include multiple network devices, and each network device may include a certain number of terminals within its coverage area, without specific limitation.

[0068] The communication system 10 may also include other network entities such as a network controller and a mobility management entity, without specific limitations.

[0069] The communication between the network devices and terminal devices in the communication system 10 can be wireless or wired communication, without any specific restrictions.

[0070] 2. PDCCH

[0071] The payload carried on the PDCCH is called DCI; that is, the PDCCH carries DCI.

[0072] A carrier can have multiple control-resource sets (CORESETs). CORESETs map resource elements to control channel elements (CCEs). One or more CCEs are aggregated together to carry PDCCHs. Terminal devices can detect whether the network has sent PDCCHs to them in the search space through blind detection.

[0073] CCEs are the basic resource units that make up a PDCCH. A PDCCH can use 1, 2, 4, 8, or 16 CCEs. The number of CCEs used can be called the aggregation level. That is, a PDCCH can be aggregated from several CCEs.

[0074] A CCE can include 6 Resource Element Groups (REGs), and each REG can include one or more Resource Blocks (RBs) on an OFDM symbol.

[0075] CORESET is a new concept in 5G NR, representing a time-frequency domain resource set. This is because in 5G NR, the transmission bandwidth of the communication system is relatively large, while the support capabilities of terminal devices vary. To adapt to different bandwidths and reduce the blind detection complexity of PDCCH, CORESET constrains the time-frequency domain resource scheduling of PDCCH.

[0076] A CORESET can have multiple search spaces, and a search space is a group of candidate control channels consisting of CCEs with the same aggregation level. Since CCEs have multiple aggregation levels, a single terminal device can correspond to multiple search spaces.

[0077] 3. Carrier aggregation

[0078] (1) Component Carrier (CC), Primary Cell (PCell), Secondary Cell (SCell)

[0079] In carrier aggregation, multiple carriers can be combined to serve a single terminal device simultaneously. This allows the terminal device to obtain greater service bandwidth and higher transmission rates. Notably, carrier aggregation does not require all carriers to be contiguous in the frequency domain, or even restricted to the same frequency band.

[0080] The NR standard's carrier aggregation can support the aggregation of up to 16 carriers. These carriers can have different bandwidths or different duplex modes.

[0081] In addition, aggregated carriers can also be called component carriers.

[0082] For example, carrier aggregation has 5 carriers, namely component carrier 0 (CC0), component carrier 1 (CC1), component carrier 2 (CC2), component carrier 3 (CC3), and component carrier 4 (CC4).

[0083] For terminal devices, those that support carrier aggregation can transmit and receive data on multiple component carriers simultaneously; those that do not support carrier aggregation can transmit and receive data on one component carrier.

[0084] In the NR standard's description of carrier aggregation, the concept of a cell is frequently used. In this application's embodiments, a single carrier (or component carrier) can be referred to as or considered a cell. Therefore, aggregated carriers can also be understood as aggregated cells. Similarly, terminal devices supporting carrier aggregation can simultaneously transmit and receive data on multiple carriers (or component carriers); that is, terminal devices supporting carrier aggregation can simultaneously transmit and receive data within multiple cells.

[0085] For example, carrier aggregation uses five carriers: CC0, CC1, CC2, CC3, and CC4. CC0 is cell 0, or in other words, 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.

[0086] In these aggregated cells, only one cell is called the primary cell, while the others are called secondary cells. The primary cell can be the cell used by the terminal device to access the network, while the secondary cells are configured by the network after the terminal device enters connected mode. The network can quickly activate or deactivate secondary cells to meet changing service requirements. Different terminal devices can be configured with different cells as primary cells.

[0087] (2) Self-carrier scheduling

[0088] Currently, in carrier aggregation scenarios, a cell either only supports self-carrier scheduling or only cross-carrier scheduling.

[0089] In the embodiments of this application, self-carrier scheduling can be represented as the scheduling authorization and transmission data of a cell being sent on the same carrier.

[0090] For example, if cell 0 supports self-carrier scheduling (or cell 0 is configured for self-carrier scheduling), the terminal device can listen to the PDCCH of cell 0 on the corresponding CC0 and obtain the relevant scheduling authorization through the DCI carried by the PDCCH. Finally, the terminal device transmits data on CC0 using this scheduling authorization. Therefore, the scheduling authorization and data transmission for cell 0 are both performed on CC0.

[0091] (3) Cross-carrier sheduling

[0092] In the embodiments of this application, cross-carrier scheduling can be represented as the scheduling authorization and transmission data of a cell being sent on different carriers.

[0093] It should be noted that if one cell uses multi-carrier scheduling to schedule another cell, then that other cell can be said to support cross-carrier scheduling.

[0094] For example, if cell 0 can schedule cell 1 across carriers, then the terminal device can only listen to the PDCCH on CC0 corresponding to cell 0 and obtain the scheduling authorization for cell 1 through the DCI carried by the PDCCH (or, in other words, the DCI can only schedule data transmission within CC1 corresponding to cell 1). The terminal device cannot listen to the PDCCH on CC1 corresponding to cell 1 to obtain its own scheduling authorization. Finally, the terminal device transmits data on CC1 using this scheduling authorization. Therefore, the scheduling authorization for cell 0 is transmitted on CC0, while the data transmission for cell 1 is transmitted on CC1. In this case, this embodiment can be said to indicate that cell 1 supports cross-carrier scheduling (or cell 1 is configured for cross-carrier scheduling).

[0095] In this embodiment, the DCI may include a carrier indicator field (CIfield). Higher-layer signaling can indicate whether cross-carrier scheduling is configured. For example, the network can configure cross-carrier scheduling for a cell through higher-layer parameters (such as crossCarrierSchedulingConfig in RRCConnectionReconfiguration). When cross-carrier scheduling is configured, the carrier indicator field is needed to indicate which component carrier the DCI is for.

[0096] 4. PDCCH's monitoring capability (blind detection capability)

[0097] The terminal device listens for a set of PDCCH candidates in one or more CORESETs on each active serving cell configured with PDCCH listening, based on the corresponding search space set. Listening (or blind detection) can be understood as receiving each PDCCH candidate and decoding it according to the DCI format being listened to.

[0098] Due to the constraints of hardware computing resources, latency, and power consumption of terminal devices, as well as the consideration of scheduling flexibility, the PDCCH listening capability is an important factor to consider when designing the PDCCH protocol.

[0099] 1) The interval of the combination of time slot (slot) and (X,Y) (span) (X) s ,Y s (Multi-slot combination)

[0100] If a 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 and determine the maximum number of PDCCH candidates or the maximum number of non-overlapping CCEs for the serving cell in each slot.

[0101] If a monitoringCapabilityConfig for a serving cell is provided to the terminal device, and monitoringCapabilityConfig = r16monitoringcapability, the terminal device can obtain an indication and determine the maximum number of PDCCH candidates or the maximum number of non-overlapping CCEs for the serving cell within each (X,Y) combination interval.

[0102] If a monitoringCapabilityConfig for a serving cell is provided to the terminal device, and monitoringCapabilityConfig = r17monitoringcapability, then the terminal device can obtain an indication and determine the status of each (X) cell. s ,Y s The maximum number of PDCCH candidates or the maximum number of non-overlapping CCEs for the serving cell within a multi-time slot combination.

[0103] If the monitoringCapabilityConfig is not provided to the terminal device, the terminal device listens to 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.

[0104] For the SCS configurations corresponding to μ=0 and μ=1, the terminal device can indicate its ability to listen to the PDCCH based on one or more (X,Y) combinations.

[0105] A span is a series of consecutive symbols in a time slot that an end device is configured to listen to the PDCCH.

[0106] Each PDCCH monitoring occasion occurs within one span.

[0107] If a terminal device listens to the PDCCH on a cell based on a span of (X,Y) combinations, then the terminal device supports the PDCCH listening opportunity in any symbol of a time slot, wherein the time slot has a minimum time interval of X symbols between the first symbols of two consecutive spans.

[0108] A span consisting of (X,Y) symbols starts from the first symbol at the start of the PDCCH listening period and ends at the last symbol at the end of the PDCCH listening period, where the maximum number of symbols in the span is Y.

[0109] For SCS configurations of μ=5 and μ=6, the terminal device can determine the configuration based on one or more (X) s ,Y s ) combined to indicate the ability to listen to the PDCCH, where X s and Y s It is the number of consecutive time slots.

[0110] If the terminal device is based on (X) s ,Y s If multiple time slots are combined and used to listen to the PDCCH on the cell, the terminal device can then use Y... s In any time slot of the time slot, the terminal device can listen to the PDCCH of the Type 1-PDCCH CSS set, Type 3-PDCCH CSS set, and USS set provided by dedicated higher-layer signaling, and ... s The terminal device can monitor the PDCCH of the Type 0 / 0A / 2-PDCCH CSS set and the Type 1-PDCCH CSS set provided by SIB1 in any time slot of the time slot. s ,Y s ) combination of X s The set of all search spaces within a time slot is used to determine the maximum number of PDCCH candidates to be listened to and the maximum number of non-overlapping CCEs.

[0111] In the embodiments of this application, the terminal device defines the span / each (X,Y) combination span on each time slot / each (X) of an active DL BWP in a serving cell. s ,Y s The ability of a terminal device to monitor PDCCH within multiple time slots in a multi-slot combination can be achieved by the terminal device in each time slot / each (X,Y) combination span / each (X) of the active DL BWP in the serving cell. s ,Y s The maximum number of PDCCH candidates that need to be monitored within a multi-slot combination and the maximum number of non-overlapping CCEs are defined.

[0112] 2) Maximum number of PDCCH candidates

[0113] In the standard protocols defined by 3GPP, the maximum number of PDCCH candidates for the serving cell in each time slot is defined by the terminal equipment. It should be noted that the maximum number of PDCCH candidates, or the maximum value of the PDCCH candidates, is not specifically limited.

[0114] For example, with different subcarrier spaces (SCS), the maximum number of PDCCH candidates for a serving cell in each slot on a DL BWP with subcarrier space configuration μ∈{0,1,2,3}. As shown in Table 1.

[0115] Table 1

[0116]

[0117] Where, if μ = 0, then If μ = 1, then The rest can be deduced in turn.

[0118] In the standard protocol specified by 3GPP, the terminal device defines the maximum number of PDCCH candidates for the serving cell within each (X,Y) combination interval.

[0119] For example, with different subcarrier spacings, the maximum number of PDCCH candidates is as follows: for a serving cell within each (X,Y) combination on a DLBWP with subcarrier spacing μ∈{0,1}. As shown in Table 2.

[0128] 3) Maximum number of non-overlapping CCEs

[0129] It should be noted that the maximum number of non-overlapping CCEs, or the maximum value of non-overlapping CCEs, is not specifically limited.

[0130] If one or more CCEs of a PDCCH candidate correspond to different CORESET indices, then these CCEs are non-overlapping, i.e., non-overlapping CCEs.

[0131] If the start symbols for receiving each PDCCH candidate are different for one or more CCEs, then these CCEs are non-overlapping, i.e., non-overlapping CCEs.

[0132] For example, with different subcarrier spacings, the maximum number of non-overlapping CCEs within each slot of a serving cell on a DL BWP with subcarrier spacing configuration μ∈{0,1,2,3}. As shown in Table 4.

[0141] In the standard protocols defined by 3GPP, the terminal equipment in each (X s ,Y s The maximum number of non-overlapping CCEs for the serving cell within a multi-time slot combination is defined.

[0142] For example, with different subcarrier spacings, for a DLBWP with subcarrier spacing μ∈{5,6}, (X s ,Y s The maximum number of non-overlapping CCEs within a multi-timeslot combination of serving cells. As shown in Table 6.

[0146] 4) Maximum number of PDCCH candidates and maximum number of non-overlapping CCEs

[0147] If the terminal device does not report PDCCH blind detection carrier aggregation (pdcch-BlindDetectionCA) parameters, or does not provide blind detection factor R (BDFactorR) parameters, then γ = R. Here, R represents the PDCCH listening capability reported by the terminal device. R can be 1 or 2.

[0148] If the terminal device reports pdcch-BlindDetectionCA, the terminal device can be instructed by BDFactorR to have γ=1 or γ=R.

[0149] ①Scenario 1

[0150] If the terminal device is configured with Each downlink cell, configured with SCS (Supply Chain Classification) μ, listens for relevant PDCCH candidates in the active DL BWP of the serving cell. Then the terminal device does not need to activate the DL BWP on the serving cell:

[0151] ◆When the service area comes from (belongs to, etc.) When there are downlink cells, listening to more than [number] cells in each time slot. PDCCH candidates or more One non-overlapping CCE;

[0152] ◆When the service area comes from (belongs to, etc.) When there are downlink cells, listening to more than [number] cells in each time slot. PDCCH candidates or more One non-overlapping CCE;

[0153] ◆When the service area comes from (belongs to, etc.) When there are multiple downlink cells, in each time slot of the CORESET with the same coreset pool index (coresetPoolIndex) value, more than [number missing] are monitored. PDCCH candidates or more Non-overlapping CCEs.

[0154] It should be noted that, in conjunction with the above formula, the number of PDCCH candidates that the terminal device does not need to listen to is referred to as the "maximum number limit of PDCCH candidates" in this application embodiment. Similarly, the number of non-overlapping CCEs that the terminal device does not need to listen to is referred to as the "maximum number limit of non-overlapping CCEs" in this application embodiment.

[0155] It can be the PDCCH listening capability reported by the terminal device, that is, the terminal device's maximum ability to listen to PDCCH candidates or non-overlapping CCEs on a certain number of carriers.

[0156] The cells in a downlink cell can be cells that support a single transmission reception point (TRP), and a single TRP can be a single CORESET pool index. That is to say, This allows you to configure μ using SCS and support the number of cells with a single TRP.

[0157] The cells in each downlink cell can be cells that support multiple TRPs and have a higher blind detection capability, i.e., γ times. A single TRP can be multiple CORESET pool indexes. That is to say, This allows you to configure μ using SCS and support the number of cells with multiple TRPs.

[0158] Additionally, if the terminal device originates from (or belongs to, etc.) If there are multiple downlink cells, the terminal device either has not configured coresetPoolIndex or has configured coresetPoolIndex. Here, coresetPoolIndex is the value from... The single value provided by all CORESETs on all DL BWPs of each serving cell in each downlink cell, i.e., a single CORESET pool index.

[0159] If the terminal device comes from (belongs to, etc.) If there are multiple downlink cells, the terminal device either has not configured coresetPoolIndex or has configured coresetPoolIndex. Here, coresetPoolIndex is the value from... Multiple values ​​are provided by all CORESETs on all DL BWPs of each serving cell in each downlink cell, i.e., multiple CORESET pool indices. For example, if the value of the coresetPoolIndex is 0, it can be used for the first CORESET; if the value of the coresetPoolIndex is 1, it can be used for the second CORESET.

[0160] ②Scenario Two

[0161] If the terminal device is configured with Each downlink cell, configured with SCS (Supply Chain Classification) μ, listens for relevant PDCCH candidates in the active DL BWP of the serving cell. Then the terminal device does not need to (i.e. will not require) in The active DL BWP on the serving cell of each downlink cell listens for more than [number] times within each time slot. PDCCH candidates or more A non-overlapping CCE. In other words, the terminal device in The active DL BWP on the serving cell of each downlink cell does not listen for more than [number] times within each time slot. No more than 1 PDCCH candidate or no more than Non-overlapping CCEs

[0162] ◆When the service area comes from (belongs to, etc.) When there are multiple downlink cells, the terminal device does not need to listen for more than [number] times in each time slot on the active DL BWP with SCS configuration μ in the serving cell. PDCCH candidates or more Non-overlapping CCEs.

[0163] ◆When the service area comes from (belongs to, etc.) When there are multiple downlink cells, the terminal device does not need to listen for more than [number] times in each time slot on the active DL BWP with SCS configuration μ in the serving cell. PDCCH candidates or more Non-overlapping CCEs.

[0164] ◆When the service area comes from (belongs to, etc.) When there are multiple downlink cells, for CORESETs with the same coresetPoolIndex value, the terminal device does not need to listen for more than [number] times in each slot on the active DLBWP with SCS configuration μ in the serving cell. PDCCH candidates or more

[0165] Non-overlapping CCEs.

[0166] It should be noted that, or This can be the number of cells with associated PDCCH candidates that are being monitored on the active DL BWP of the serving cell using all SCS configurations μ.

[0167] This can be the number of cells with associated PDCCH candidates that the active DL BWP of the serving cell configured with a certain SCS is listening to.

[0168] The following embodiments of this application provide an exemplary description of "Scenario Two".

[0169] For example, if the following conditions exist:

[0170] • The PDCCH monitoring capability reported by the terminal device is That is, it supports the ability to monitor PDCCH carriers with a maximum of 4 carriers and non-overlapping CCEs;

[0171] The terminal device is configured with 5 cells, none of which have multiple CORESET pool indexes configured, and all 5 cells originate from [a specific source]. One downlink cell, i.e.

[0172] • In these 5 cells, PDCCH can be sent on Pcell and scell 1;

[0173] The SCS of Pcell is 15kHz, i.e., μ = 0. Pcell supports self-carrier scheduling and can schedule Scell ​​2 and Scell ​​4 across carriers; that is, Scell ​​2 and Scell ​​4 support cross-carrier scheduling. In this case, Pcell can be called the scheduling cell, and Scell ​​2 and Scell ​​4 can be called the scheduled cells.

[0174] • Scell ​​1 has an SCS of 30kHz, i.e., μ = 1, and supports self-carrier scheduling. Scell ​​1 can also schedule Scell ​​3 across carriers, meaning Scell ​​3 supports cross-carrier scheduling.

[0175] because In the formula for "Scenario 2", the limit on the number of PDCCH candidates or the limit on the number of non-overlapping CCEs in each time slot is calculated based on the SCS of the scheduled cell, therefore the following applies:

[0176] For Scell ​​2 and Scell ​​4, since the SCS of Pcell is 15kHz, i.e., μ=0, the terminal device does not need to listen for more than 15kHz in each time slot on the active DL BWP of Pcell with SCS configuration μ=0. There are 10 PDCCH candidates; among them, according to Table 1 above,

[0177] For Scell ​​2 and Scell ​​4, since the SCS of Pcell is 15kHz, i.e., μ=0, the terminal device does not need to listen for more than 15kHz in each time slot on the active DL BWP of Pcell with SCS configuration μ=0. There are 1 non-overlapping CCEs; among which, according to Table 4 above.

[0178] For Scell ​​3, since the SCS of Scell ​​1 is 30kHz (μ=1), the terminal device does not need to listen for more than [a certain number of kHz] in each time slot on the active DL BWP of Scell ​​1 with SCS configuration μ=1. There are 10 PDCCH candidates; among them, according to Table 1 above,

[0179] For Scell ​​3, since the SCS of Scell ​​1 is 30kHz (μ=1), the terminal device does not need to listen for more than [a certain number of kHz] in each time slot on the active DL BWP of Scell ​​1 with SCS configuration μ=1. There are 1 non-overlapping CCEs; among which, according to Table 4 above.

[0180] ③Scenario 3

[0181] If the terminal device is configured with Each downlink cell, configured with SCS, listens for relevant PDCCH candidates in the active DLBWP of the serving cell, and In each downlink cell Each downlink cell uses a span with an (X,Y) combination for PDCCH monitoring, where but

[0182] ◆When the service area comes from (belongs to, etc.) When there are multiple downlink cells, the terminal device does not need to listen for more than [number] times within each span of the active DL BWP with SCS configuration μ in the serving cell. PDCCH candidates or more Non-overlapping CCEs.

[0183] It should be noted that, It can be the PDCCH listening capability reported by the terminal device, that is, the terminal device's maximum ability to listen to PDCCH candidates or non-overlapping CCEs on a certain number of carriers.

[0184] This can be configured using SCS to determine the number of cells with associated PDCCH candidates being monitored on the active DL BWP of the serving cell of μ.

[0185] This can be the number of cells with associated PDCCH candidates that are monitored within the span of the (X,Y) combination on the active DL BWP of the serving cell configured with SCS.

[0186] ④Scenario 4

[0187] If the terminal device is configured with Each downlink cell, configured with SCS, listens for relevant PDCCH candidates in the active DLBWP of the serving cell, and In each downlink cell Each downlink cell uses a span with an (X,Y) combination for PDCCH monitoring, where Then the terminal device does not need to be in The service cell of the downlink cell is activated, and the listening time within each span on the DL BWP exceeds [number missing]. PDCCH candidates or more Non-overlapping CCEs.

[0188] ◆When the service area comes from (belongs to, etc.) When there are multiple downlink cells, the terminal device does not need to listen for more than [number] times within each span of the active DL BWP with SCS configuration μ in the serving cell. PDCCH candidates or more Non-overlapping CCEs.

[0189] ⑤ Situation 5

[0190] Based on the above, it can be seen that the terminal device does not need to activate each (X) DL BWP with SCS configuration μ on the serving cell. s ,Y s The combination of multi-timeslot intra-monitoring exceeds PDCCH candidates or more Non-overlapping CCEs.

[0191] Alternatively, the terminal device does not need to activate each (X) DL BWP with SCS configuration μ on the serving cell. s ,Y s The combination of multi-timeslot intra-monitoring exceeds PDCCH candidates or more Non-overlapping CCEs.

[0192] in,

[0193]

[0194] 5. A PDCCH monitoring method

[0195] As can be seen from the above, in carrier aggregation scenarios, a cell either only supports self-carrier scheduling or only cross-carrier scheduling. Regardless of whether it is self-carrier scheduling or cross-carrier scheduling, the terminal device needs to listen to (or blindly detect) the PDCCH according to the maximum number of PDCCH candidates or the maximum number of non-overlapping CCEs to obtain the DCI.

[0196] Currently, the DCI carried by the PDCCH transmitted on a cell can only schedule data transmission within one carrier (or CC). This will result in terminal devices needing to consume a lot of power to listen to (or blindly detect) the PDCCH of each cell in carrier aggregation scenarios, especially when there are many aggregated cells and a large traffic volume.

[0197] For example, when there are 16 cells in the aggregation and the downlink traffic is large, if downlink data needs to be scheduled on these 16 cells, and one DCI can only schedule data transmission within one cell, then the terminal device needs to listen to the PDCCH of each cell separately, requiring a total of 16 PDCCHs to be listened to (one PDCCH carries one DCI), which results in the terminal device consuming a lot of power in listening to the PDCCH.

[0198] To reduce the monitoring complexity of PDCCH and save power, this application introduces a DCI that can schedule data transmission in multiple carriers (or multiple CCs), i.e., multi-carrier scheduling, thereby reducing the monitoring complexity of PDCCH and saving power through multi-carrier scheduling.

[0199] For example, when there are 16 cells in an aggregation and the downlink traffic is large, if downlink data needs to be scheduled across these 16 cells, and one DCI can schedule data transmission within these 16 cells, then the terminal device only needs to listen to one PDCCH (one PDCCH carries one DCI). Compared to one DCI scheduling data transmission within one cell, scheduling data transmission across all 16 cells with one DCI reduces the complexity of PDCCH listening, thereby reducing the significant power consumption of the terminal device in listening to the PDCCH, i.e., reducing PDCCH listening complexity to save power.

[0200] In specific implementation, when there are scheduled cells supporting multi-carrier scheduling among M cells (M is an integer greater than 1), the embodiments of this application can determine the maximum number of PDCCH candidates and / or the maximum number of non-overlapping CCEs of the scheduled cells among the M cells within a time unit by means of protocol specification, pre-configuration, or network configuration. This allows the terminal device to listen to PDCCH according to the maximum number of PDCCH candidates and / or the maximum number of non-overlapping CCEs, thereby reducing the complexity of PDCCH listening by the terminal device and potentially saving power consumption.

[0201] Furthermore, since this application embodiment introduces multi-carrier scheduling, a scheduled cell may only support multi-carrier scheduling, may simultaneously support multi-carrier scheduling and self-carrier scheduling, or may simultaneously support multi-carrier scheduling and cross-carrier scheduling. Therefore, when multi-carrier scheduling is supported, the maximum number of PDCCH candidates and / or the maximum number of non-overlapping CCEs in this application embodiment need to be determined (or divided) according to the number of scheduling cells regulated by the scheduled cell and the scheduling types supported by the scheduled cell. The scheduling types supported by the scheduled cell include: scheduling where the scheduled cell only supports multi-carrier scheduling, and scheduling where the scheduled cell supports both multi-carrier scheduling and self-carrier scheduling or cross-carrier scheduling.

[0202] To achieve the above technical solution, the following provides further explanations of other content, concepts, and meanings that may be involved.

[0203] (1) Multicarrier scheduling

[0204] In the embodiments of this application, multi-carrier scheduling can be expressed as follows: the DCI carried by the PDCCH transmitted on a cell can schedule data transmission within multiple carriers (multiple CCs or multiple cells). However, in cross-carrier scheduling and self-carrier scheduling, the DCI carried by the PDCCH transmitted on a cell can only schedule data transmission within one carrier (or CC).

[0205] In other words, multi-carrier scheduling refers to the situation where a DCI schedules data transmission within multiple carriers (or CCs), while cross-carrier scheduling and self-carrier scheduling refer to the situation where a DCI schedules data transmission within a single carrier (or CC).

[0206] It should be noted that if one cell uses multi-carrier scheduling to schedule other cells, then those other cells can be said to support multi-carrier scheduling.

[0207] For example, if cell 0 (CC0) can schedule cell 1 (CC1) and cell 2 (CC2) using multiple carriers, then cell 1 (CC1) and cell 2 (CC2) can support multiple carrier scheduling.

[0208] In addition, in conjunction with the content in "3. Carrier Aggregation" above, in this application example, a cell can support multi-carrier scheduling, can simultaneously support multi-carrier scheduling and self-carrier scheduling, and can simultaneously support multi-carrier scheduling and cross-carrier scheduling.

[0209] Similarly, a carrier (or a CC) can support multi-carrier scheduling, can simultaneously support multi-carrier scheduling and self-carrier scheduling, and can simultaneously support multi-carrier scheduling and cross-carrier scheduling.

[0210] (2) M cells, scheduling cells and scheduled cells

[0211] Based on the content in "3. Carrier Aggregation" above, in this application embodiment, a carrier (or a CC) can be referred to as or regarded as a cell, and a terminal device that supports carrier aggregation can send and receive data in multiple cells simultaneously.

[0212] Therefore, in this embodiment, the M cells can be cells under carrier aggregation. That is, the terminal device can have M cells or M carriers aggregated. Each of the M cells corresponds to one carrier (or one CC).

[0213] Since this application embodiment introduces multi-carrier scheduling, there are cells among the M cells that support multi-carrier scheduling. That is, there are cells among the M cells that support multi-carrier scheduling by other cells.

[0214] Furthermore, among these M cells, if one cell can schedule another cell using multiple carriers, then that one cell can be called or regarded as the "scheduling cell," and the other cell can be called or regarded as the "scheduled cell." In other words, the scheduled cell supports multi-carrier scheduling.

[0215] For example, if cell 0 (CC0) schedules cell 1 (CC1) using multiple carriers, then cell 0 (CC0) is the scheduling cell and cell 1 (CC1) is the scheduled cell.

[0216] It should be noted that the scheduling cell can also be called the multi-carrier scheduling cell, the multi-carrier scheduling cell, etc., and there is no specific restriction on it.

[0217] The scheduled cell can also be called the scheduled cell in multi-carrier scheduling, the cell that is scheduled by multi-carrier, etc., without any specific restrictions.

[0218] (3) The scheduled cell is scheduled by N (N is an integer greater than or equal to 1) scheduling cells.

[0219] In the embodiments of this application, a scheduled cell can be scheduled by one (i.e., N equals 1) scheduling cell or by multiple (i.e., N is greater than 1) scheduling cells.

[0220] For example, if cell 0 (CC0) schedules cell 1 (CC1) and cell 2 (CC2) using multiple carriers, and cell 3 (CC3) schedules cell 1 (CC1) using multiple carriers, 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).

[0221] (4) The scheduled cell supports self-carrier scheduling or cross-carrier scheduling.

[0222] In the embodiments of this application, a scheduled cell may support only multi-carrier scheduling, may support both multi-carrier scheduling and self-carrier scheduling (supporting both multi-carrier scheduling and self-carrier scheduling), or may support both multi-carrier scheduling and cross-carrier scheduling (supporting both multi-carrier scheduling and cross-carrier scheduling).

[0223] For example, such as Figure 2 As shown, the carrier aggregation cells include cells 0 (CC0) to 4 (CC4). On cell 0 (CC0), a single DCI can schedule cells 1 (CC1), 2 (CC2), 3 (CC3), and 4 (CC4) using multiple carriers. Therefore, cells 1 (CC1) to 4 (CC4) can only be scheduled by cell 0 (CC0), and cells 1 (CC1) to 4 (CC4) only support multi-carrier scheduling.

[0224] For example, such as Figure 3 As shown, the carrier aggregation cells include cells 0 (CC0) to 4 (CC4). On cell 0 (CC0), a single DCI can schedule cells 1 (CC1), 2 (CC2), 3 (CC3), and 4 (CC4) using multiple carriers. Cell 1 (CC1) can perform self-carrier scheduling, and cell 2 (CC2) can be scheduled across carriers by cell 1 (CC1). Therefore, cell 1 (CC1) supports both multi-carrier scheduling and self-carrier scheduling, but does not support cross-carrier scheduling; cell 2 (CC2) supports both multi-carrier scheduling and cross-carrier scheduling, but does not support cross-carrier scheduling; cells 3 (CC3) and 4 (CC4) only support multi-carrier scheduling.

[0225] For example, such as Figure 4 As shown, the carrier aggregation cells include cells 0 (CC0) to 4 (CC4). On cell 0 (CC0), a single DCI can schedule multiple carriers of cells 1 (CC1), 2 (CC2), 3 (CC3), and 4 (CC4), while on cell 5 (CC5), a single DCI can schedule multiple carriers of cells 1 (CC1), 2 (CC2), and 3 (CC3). Cell 1 (CC1) can be scheduled by its own carrier, and cell 2 (CC2) can be scheduled across carriers from 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 cells 3 (CC3) and 4 (CC4) only support multi-carrier scheduling.

[0226] (5) First Information

[0227] In order to determine the maximum number of PDCCH candidates or the maximum number of non-overlapping CCEs for the scheduled cells in M ​​cells within a time unit by means of network configuration, the embodiments of this application introduce first information, which enables the network device to determine the maximum number of PDCCH candidates or the maximum number of non-overlapping CCEs for the scheduled cells in M ​​cells within a time unit by means of the first information.

[0228] In addition, the first information may also be described using other terms, such as configuration information or instruction information, as long as they have the same meaning / function / explanation / concept, they are all within the scope of protection claimed in the embodiments of this application.

[0229] In some possible implementations, the first information may be sent or obtained during processes such as cell search, cell reselection, uplink / downlink synchronization, cell access, cell dwell, initial access, or uplink / downlink resource scheduling.

[0230] In some possible implementations, the initial information can be carried by system information (SI), higher-layer signaling (such as RRC signaling), terminal device-specific signaling, etc.

[0231] In some possible implementations, the first information may include at least one of the following: the subcarrier spacing of the scheduled cell, the subcarrier spacing of the scheduled cell, the PDCCH listening capability reported by the terminal device, the number of cells M, the self-carrier scheduling factor or the cross-carrier scheduling factor, and the multi-carrier scheduling factor.

[0232] It should be noted that the subcarrier spacing of the scheduled cell, the subcarrier spacing of the scheduled cell, the PDCCH listening capability reported by the terminal device, the number of cells M, the self-carrier scheduling factor or cross-carrier scheduling factor, and the multi-carrier scheduling factor will be explained below.

[0233] (6) Time unit

[0234] In the embodiments of this application, a time unit can be understood as the communication granularity in the time domain. For example, terminal devices and network devices communicate in the time domain with time units as the granularity / unit.

[0235] In some possible implementations, the time unit can be a time slot, an interval (span) combining (X,Y), or (X... s ,Y s One of the multiple time slots in the combination.

[0236] (7) Supports the maximum number of PDCCH candidates and the maximum number of non-overlapping CCEs under multi-carrier scheduling.

[0237] It should be noted that in the above "4) Maximum number of PDCCH candidates and maximum number of non-overlapping CCEs", the embodiments of this application only address the maximum number of PDCCH candidates and the maximum number of non-overlapping CCEs when the cell only supports self-carrier scheduling or cross-carrier scheduling. However, the maximum number of PDCCH candidates and the maximum number of non-overlapping CCEs when the cell supports multi-carrier scheduling requires further research.

[0238] Since the embodiments of this application need to determine (or divide) the maximum number of PDCCH candidates and / or the maximum number of non-overlapping CCEs according to the number of scheduling cells (such as N) of the scheduled cell and the scheduling type supported by the scheduled cell, and the value of N and the scheduling type supported by the scheduled cell are different, the embodiments of this application will be described in different cases below.

[0239] Scenario 1:

[0240] Among the M cells, there exists a scheduling cell that schedules multiple scheduled cells, and the scheduled cells only support multi-carrier scheduling.

[0241] In other words, a scheduled cell is scheduled by one (i.e., N=1) scheduled cell, and the scheduled cell only supports multi-carrier scheduling.

[0242] Therefore, in "Scenario 1", the embodiments of this application may not need to determine (or divide) the maximum number of PDCCH candidates and / or the maximum number of non-overlapping CCEs for the scheduled cell within a time unit, and may adopt the methods described in "Scenario 1", "Scenario 2", "Scenario 3", "Scenario 4" and "Scenario 5" above. Here, the time unit is the span / (X,Y) combination of the time slot / (X) on the active DL BWP of the scheduled cell. s ,Y s The SCS configuration μ is the subcarrier interval corresponding to the scheduling cell, which is a combination of multiple time slots.

[0243] For example, in Figure 2 In this context, cell 1 (CC1) is multi-carrier scheduled by cell 0 (CC0), and cell 1 (CC1) only supports multi-carrier scheduling. Therefore, embodiments of this application can configure the span / (X,Y) combination of the time slot / (X) on the active DL BWP of cell 1 (CC1) of the terminal device. s ,Y s The maximum number of PDCCH candidates and / or the maximum number of non-overlapping CCEs within a multi-slot combination.

[0244] Scenario 2:

[0245] Among M cells, there are multiple scheduling cells that schedule multiple scheduled cells, and these multiple scheduled cells only support multi-carrier scheduling.

[0246] In other words, a scheduled cell is scheduled by N (1 < N < M) scheduled cells, and the scheduled cell only supports multi-carrier scheduling.

[0247] Therefore, in "Scenario 2", the embodiments of this application can determine (or divide) the maximum number of PDCCH candidates and / or the maximum number of non-overlapping CCEs for the scheduled cell within a time unit for the terminal device. Here, the time unit is the span / (X,Y) combination of the time slot / (X) on the active DL BWP of the scheduled cell. s ,Y s The SCS configuration μ is the subcarrier interval corresponding to the scheduling cell, which is a combination of multiple time slots.

[0248] In “Scenario 2”, the embodiments of this application can configure N (1 < N < M) multicarrier scheduling factors via higher-layer signaling, i.e., b i , i = {1, 2, ..., N} The maximum number of PDCCH candidates is determined (or divided) into N parts that support multi-carrier scheduling by using the N multi-carrier scheduling factors. Each part needs to be multiplied by a corresponding multi-carrier scheduling factor.

[0249] Similarly, in "Scenario 2", the embodiments of this application can configure N multi-carrier scheduling factors through higher-layer signaling, i.e., b i , i = {1, 2, ..., N} The maximum number of non-overlapping CCEs is determined (or divided) into N parts by using the N multi-carrier scheduling factors, and each part needs to be multiplied by a corresponding multi-carrier scheduling factor.

[0250] Additionally, 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 portions that support multi-carrier scheduling. The multi-carrier scheduling factor can also be described using other terms, without specific restrictions.

[0251] For example, in Figure 4In this embodiment, 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 application embodiment, two multi-carrier scheduling factors can be configured for cell 3 through higher-layer signaling, namely the multi-carrier scheduling factor of CC0 and the multi-carrier scheduling factor of CC5. These two multi-carrier scheduling factors are used to determine (or divide) the maximum number of PDCCH candidates or the maximum number of non-overlapping CCEs for cell 3 into two parts that support multi-carrier scheduling.

[0252] Scenario 3:

[0253] Among M cells, there exists a scheduling cell that schedules multiple scheduled cells, and among these multiple scheduled cells, all or some of the scheduled cells support both multi-carrier scheduling and self-carrier scheduling or cross-carrier scheduling.

[0254] In other words, a scheduled cell is scheduled by one (i.e., N=1) scheduled cell, and the scheduled cell supports both multi-carrier scheduling and self-carrier scheduling or cross-carrier scheduling.

[0255] Therefore, in “Scenario 3”, the embodiments of this application can determine (or divide) the maximum number of PDCCH candidates and the maximum number of non-overlapping CCEs for the scheduled cell within a time unit by the terminal device.

[0256] • If the scheduled cell supports multi-carrier scheduling and self-carrier scheduling, then the time unit is divided into:

[0257] The span / (X,Y) combination of the time slot / (X) combination on the activation DL BWP of the scheduling cell s ,Y s () Combinations of multiple time slots; and,

[0258] The span / (X) combination of the time slot / (X) on the active DL BWP of the scheduled cell s ,Y s (Multi-time slot combination)

[0259] • If the scheduled cell supports multi-carrier scheduling and self-carrier scheduling, then the SCS configuration μ is divided into:

[0260] The subcarrier spacing corresponding to the scheduling cell, i.e., μ MS ;and,

[0261] The subcarrier spacing corresponding to the scheduled cell, i.e., μ MSd .

[0262] For example, if cell 0 uses multicarrier scheduling for cells 1 and 2, and cell 1 supports subcarrier scheduling, then μ MS For cell 0, the subcarrier spacing is μ.MSd The subcarrier spacing of cell 1.

[0263] • If the scheduled cell supports multi-carrier scheduling and cross-carrier scheduling, then the time unit is divided into:

[0264] The span / (X,Y) combination of the time slot / (X) combination on the activation DL BWP of the scheduling cell s ,Y s () Combinations of multiple time slots; and,

[0265] Cross-carrier scheduling of the active DL BWP of the scheduled cell, the span / (X) combination of the time slot / (X) combination. s ,Y s (Multi-time slot combination)

[0266] For example, if cell 0 schedules cell 1 and cell 2 using multiple carriers, and cell 1 schedules cell 2 across carriers, then cell 1 is a cell that schedules cell 2 across carriers.

[0267] • If the scheduled cell supports multi-carrier scheduling and cross-carrier scheduling, then the SCS configuration μ is divided into:

[0268] The subcarrier spacing corresponding to the scheduling cell, i.e., μ MS ;and,

[0269] Cross-carrier scheduling of the subcarrier interval corresponding to the scheduled cell, i.e., μ. MSd .

[0270] For example, if cell 0 schedules cell 1 and cell 2 using multiple carriers, and cell 1 schedules cell 2 across carriers, then cell 1 is the cell that schedules cell 2 across carriers, μ MS For cell 0, the subcarrier spacing is μ. MSd The subcarrier spacing of cell 1.

[0271] In “Scenario 3”, the embodiments of this 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 higher-layer signaling, and a+b≤1.

[0272] Then, the maximum number of PDCCH candidates is determined (or divided) into two parts by a and b. One part that supports self-carrier scheduling (or cross-carrier scheduling) needs to be multiplied by a, and the other part that supports multi-carrier scheduling needs to be multiplied by b.

[0273] In other words, 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 higher-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 higher-layer signaling.

[0274] 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 of PDCCH candidates or the maximum number of non-overlapping CCEs into the portion supporting self-carrier scheduling. The self-carrier scheduling factor can also be described using other terms, without specific restrictions.

[0275] A cross-carrier scheduling factor can be understood as a weighting factor that aims to determine (or divide) the maximum number of PDCCH candidates or the maximum number of non-overlapping CCEs into portions that support cross-carrier scheduling. The cross-carrier scheduling factor can also be described using other terms, without specific restrictions.

[0276] For example, in Figure 3 In this embodiment, 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 application embodiment, one multi-carrier scheduling factor and one self-carrier scheduling factor can be configured for cell 1 (CC1) through higher-layer signaling, thereby determining (or dividing) the maximum number of PDCCH candidates or the maximum number of non-overlapping CCEs for cell 1 (CC1) into a part that supports multi-carrier scheduling and a part that supports self-carrier scheduling.

[0277] For example, in Figure 3 In this embodiment, 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 application embodiment, one multi-carrier scheduling factor and one cross-carrier scheduling factor can be configured for cell 2 (CC2) through higher-layer signaling, thereby determining (or dividing) the maximum number of PDCCH candidates or the maximum number of non-overlapping CCEs for cell 2 (CC2) into a part that supports multi-carrier scheduling and a part that supports cross-carrier scheduling.

[0278] Scenario 4:

[0279] Among M cells, there are multiple scheduling cells that schedule multiple scheduled cells, and some of these scheduled cells support both multi-carrier scheduling and self-carrier scheduling or cross-carrier scheduling.

[0280] In other words, a scheduled cell is scheduled by N (1 < N < M) scheduling cells, and the scheduled cell supports both multi-carrier scheduling and self-carrier scheduling or cross-carrier scheduling.

[0281] Therefore, in “Scenario 4”, the embodiments of this application can determine (or divide) the maximum number of PDCCH candidates and the maximum number of non-overlapping CCEs for the scheduled cell within a time unit by the terminal device.

[0282] • If the scheduled cell supports multi-carrier scheduling and self-carrier scheduling, then the time unit is divided into:

[0283] The span / (X,Y) combination of the time slot / (X) combination on the activation DL BWP of the scheduling cell s ,Y s () Combinations of multiple time slots; and,

[0284] The span / (X) combination of the time slot / (X) on the active DL BWP of the scheduled cell s ,Y s (Multi-time slot combination)

[0285] • If the scheduled cell supports multi-carrier scheduling and self-carrier scheduling, then the SCS configuration μ is divided into:

[0286] The subcarrier spacing corresponding to the scheduling cell, i.e., μ MS ;and,

[0287] The subcarrier spacing corresponding to the scheduled cell, i.e., μ MSd .

[0288] • If the scheduled cell supports multi-carrier scheduling and cross-carrier scheduling, then the time unit is divided into:

[0289] The span / (X,Y) combination of the time slot / (X) combination on the activation DL BWP of the scheduling cell s ,Y s () Combinations of multiple time slots; and,

[0290] Cross-carrier scheduling of the active DL BWP of the scheduled cell, the span / (X) combination of the time slot / (X) combination. s ,Y s (Multi-time slot combination)

[0291] • If the scheduled cell supports multi-carrier scheduling and cross-carrier scheduling, then the SCS configuration μ is divided into:

[0292] The subcarrier spacing corresponding to the scheduling cell, i.e., μ MS ;and,

[0293] Cross-carrier scheduling of the subcarrier interval corresponding to the scheduled cell, i.e., μ. MSd .

[0294] In “Scenario 4”, the embodiments of this application can configure one self-carrier scheduling factor (or one cross-carrier scheduling factor), i.e., a, and N (1 < N < M) multi-carrier scheduling factors, i.e., b, through higher-layer signaling. i , i={1,2,...,N}, and

[0295] Then, through a and b i The maximum number of PDCCH candidates needs to be determined (or divided) into N+1 parts, one multiplied by 'a', and the others multiplied by 'b'. i .

[0296] For example, in Figure 4 In this embodiment, cell 1 (CC1) is multi-carrier scheduled by cell 0 (CC0) and cell 5 (CC5), and cell 1 (CC1) supports both multi-carrier scheduling and self-carrier scheduling. Therefore, in this embodiment, two multi-carrier scheduling factors can be configured for cell 1 (CC1) through higher-layer signaling, namely multi-carrier scheduling of cell 0 (CC0) and multi-carrier scheduling of cell 5 (CC5), and one self-carrier scheduling factor. In this way, the maximum number of PDCCH candidates or the maximum number of non-overlapping CCEs for cell 1 (CC1) can be determined (or divided) into a part that supports multi-carrier scheduling and a part that supports self-carrier scheduling.

[0297] For example, in Figure 4 In this embodiment, cell 2 (CC2) is multi-carrier scheduled by cell 0 (CC0) and cell 5 (CC5), and cell 2 (CC2) supports both multi-carrier scheduling and cross-carrier scheduling. Therefore, in this embodiment, two multi-carrier scheduling factors can be configured for cell 2 (CC2) through higher-layer signaling, namely multi-carrier scheduling of cell 0 (CC0) and multi-carrier scheduling of cell 5 (CC5), and one cross-carrier scheduling factor. In this way, the maximum number of PDCCH candidates or the maximum number of non-overlapping CCEs for cell 2 (CC2) can be determined (or divided) into a part that supports multi-carrier scheduling and a part that supports cross-carrier scheduling.

The network device can also be a chip / chip module / device, etc., and the terminal device can also be a chip / chip module / device, etc., without specific limitations.

[0452] like Figure 5 The diagram shown is a flowchart of a PDCCH monitoring method according to an embodiment of this application, which specifically includes the following steps:

[0453] S510. The network device sends first information, which is used to determine the maximum number of PDCCH candidates or the maximum number of non-overlapping CCEs for the scheduled cells in M ​​cells within a time unit.

[0454] Among them, the scheduled cell is the cell that supports multi-carrier scheduling.

[0455] Among them, multi-carrier scheduling refers to the DCI scheduling of data transmission within multiple scheduled cells carried by the PDCCH sent by the scheduling cell in M ​​cells.

[0456] Where M is an integer greater than 1.

[0472] If the scheduled cell is scheduled by a single scheduling cell, and the scheduled cell only supports multi-carrier scheduling, then the maximum number of non-overlapping CCEs is limited to a first-class non-overlapping CCE limit, which corresponds to multi-carrier scheduling.

[0473] In some possible implementations, the maximum number of first-class non-overlapping CCEs is limited by the maximum number of first-class non-overlapping CCEs and the maximum number of second-class non-overlapping CCEs;

[0475] The maximum number of the second non-overlapping CCEs is determined by the PDCCH listening capability reported by the terminal device, the maximum number of the first non-overlapping CCEs, the number of cells corresponding to the subcarrier interval of the scheduled cell, and the number of cells corresponding to all subcarrier intervals in the M cells.

[0476] In some possible implementations, the maximum number of PDCCH candidates is determined based on the number of scheduling cells that the scheduled cell is scheduled to have and the scheduling types supported by the scheduled cell, including:

[0477] If a scheduled cell is scheduled by N scheduling cells, where N is an integer greater than or equal to 1, and the scheduled cell supports multi-carrier scheduling, self-carrier scheduling, or cross-carrier scheduling, then

[0478] The maximum number of PDCCH candidates is limited to one second-type PDCCH candidate and N first-type PDCCH candidates. The maximum number of second-type PDCCH candidates corresponds to self-carrier scheduling or cross-carrier scheduling, while the maximum number of first-type PDCCH candidates corresponds to multi-carrier scheduling.

[0479] In some possible implementations, the maximum number of second-type PDCCH candidates is limited to a1 times the maximum number of first-type PDCCH candidates, where a1 is the self-carrier scheduling factor or cross-carrier scheduling factor in the first information;

[0480] The maximum number of i-th type I PDCCH candidates is limited by the maximum number of first PDCCH candidates. times, Let be the multicarrier scheduling factor of the i-th scheduling cell in the first information, and

[0481] The maximum number of first PDCCH candidates is limited by the maximum number of third PDCCH candidates and the maximum number of fourth PDCCH candidates.

Whether a function is executed in a hardware or computer software-driven hardware manner depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of this application.

For example, each function can be divided into different functional units, or two or more functions can be integrated into one processing unit. The integrated unit can be implemented in hardware or as a software program module. It should be noted that the unit division in this application embodiment is illustrative and only represents a logical functional division, while other division methods may be used in actual implementation.

[0512] For example, the acquisition unit 601 and the listening unit 602 can be integrated into the communication unit. The communication unit can be a communication interface, transceiver, transceiver circuit, etc.

[0513] For example, the acquisition unit 601 and the listening unit 602 can be integrated into the processing unit.

The physical downlink control channel monitoring device 600 determines the maximum number of PDCCH candidates and / or the maximum number of non-overlapping CCEs of the scheduled cells in the M cells within a time unit through the first information. This allows the physical downlink control channel monitoring device 600 to perform PDCCH monitoring according to the maximum number of PDCCH candidates and / or the maximum number of non-overlapping CCEs.
