[0147] In some embodiments, access network devices, core network devices, or network devices can be replaced by terminals. For example, embodiments of this disclosure can also be applied to structures where communication between access network devices, core network devices, or network devices and terminals is replaced by communication between multiple terminals (e.g., device-to-device (D2D), vehicle-to-everything (V2X), etc.).

[0152] Figure 1 This is a schematic diagram of the architecture of a communication system provided according to embodiments of this disclosure. Figure 1 As shown, the communication system 100 includes a terminal 101 and a network device 102.

[0153] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0154] In some embodiments, network device 102 may be an access network device. It should be noted that network device 102 may be other types of network devices, such as core network devices.

[0155] In some embodiments, the access network device is, for example, a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.

[0156] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0157] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0158] In some embodiments, the communication system 100 described above may be a 4G communication system, a 5G communication system, or a 6G communication system. It should be noted that the communication system 100 may also be other communication systems, and this disclosure does not specifically limit it.

[0159] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0160] The following embodiments of this disclosure can be applied to Figure 1 The communication system 100 shown, or a part of the main body of the communication system 100, but not limited thereto. Figure 1 The entities shown are illustrative; the communication system 100 may include... Figure 1 All or part of the main body, or may include Figure 1 Other entities besides the main body, the number and form of each entity are arbitrary, each entity can be physical or virtual, the connection relationship between the entities is illustrative, the entities can be unconnected or connected, and the connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0161] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Futuregeneration radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0162] In communication systems, blind detection is an important mechanism for UE to detect PDCCH. In some embodiments, the UE may not know the location, format, and content of the PDCCH carrying DCI sent by the base station. In such cases, the UE needs to attempt to decode possible DCI candidates in the PDCCH search space through blind detection. It is understood that blind detection can also be called PDCCH blind detection, DCI blind detection, etc., and this disclosure does not specifically limit it.

[0163] In some embodiments, key elements involved in blind testing may include: search space, aggregation level, DCI format, RNTI, and control resource set (CORESET).

[0164] In some embodiments, the search space can refer to the set of PDCCH candidates that the UE needs to detect during blind detection. The search space and its associated CORESET define the time-frequency resources (e.g., CCE locations) on which the UE needs to attempt to decode DCI. In some embodiments, the search space can include a common search space (CSS) and a UE-specific search space (USS). In some embodiments, the common search space can be used to transmit common control information that all UEs need to receive. For example, in the common search space, the UE can listen for system information blocks (SIBs), paging messages, random access responses (RARs), etc. In some embodiments, the UE-specific search space can be used to transmit dynamic scheduling information for a specific UE. For example, in the UE-specific search space, PDSCH, PUSCH, etc., can be dynamically scheduled.

[0165] In some embodiments, the aggregation level (AL) can refer to the number of consecutive CCEs occupied by a PDCCH candidate. In one example, the aggregation level can be 1, 2, 4, 8, 16, etc.

[0166] In some embodiments, considering the complexity of blind detection, the blind detection performed on the terminal may be subject to the following constraint: the number of PDCCH candidates that the terminal can blindly detect does not exceed a first number.

[0167] In some embodiments, considering the complexity of channel estimation, blind detection performed on a terminal may be subject to the following constraint: the number of non-overlapping CCEs corresponding to PDCCH candidates does not exceed a second number.

[0168] In some embodiments, the terminal may receive indication signaling, which may be RRC signaling. In some embodiments, the indication signaling received by the terminal may include a monitoringCapabilityConfig information element (IE). In some embodiments, the RRC signaling may configure the PDCCH monitoring capability of R15, R16, or R17 versions on the serving cell. In one example, the RRC signaling may indicate a first monitoring capability. For example, the first monitoring capability may be the monitoring capability of the R15 version of the PDCCH. In this case, the value of the monitoringCapabilityConfig information element may be r15monitoringcapability, thus enabling the monitoring capability of the R15 version of the PDCCH. In one example, the RRC signaling may indicate a second monitoring capability. For example, the second monitoring capability may be the monitoring capability of the R16 version of the PDCCH. In this case, the value of the monitoringCapabilityConfig information element may be r16monitoringcapability, thus enabling the monitoring capability of the R16 version of the PDCCH. In one example, the RRC signaling may indicate a third monitoring capability. For example, the third monitoring capability may be the monitoring capability of the R17 version of the PDCCH. At this time, if the value of the monitoringCapabilityConfig information element is r17monitoringcapability, then the multi-slot monitoring capability of the PDCCH in version R17 is enabled.

[0169] In some embodiments, the first listening capability may be a basic PDCCH support capability. In some embodiments, the second listening capability may be a PDCCH capability that supports URLLC features. In some embodiments, the third listening capability may be a PDCCH capability that supports high-frequency communication.

[0170] In some embodiments, the indication signaling may indicate r15monitoringcapability, in which case the maximum number of PDCCH candidates and / or the maximum number of non-overlapping CCEs that the terminal can support may be defined per slot. For example, based on the configuration of the search space on the currently active BWP, the terminal counts the number of configured PDCCH candidates and / or the number of non-overlapping CCEs within a single slot and determines whether this number exceeds the maximum number that the terminal can support. In some embodiments, this maximum number may be defined based on the following Tables 1A and 1B:

[0171]

[0172] Table 1A: Maximum number of PDCCH candidates monitored by a DL BWP for a single serving cell with SCS configured as μ∈{0,1,2,3}

[0173]

[0174] Table 1B: Maximum number of non-overlapping CCEs for a single serving cell and for a DL BWP with SCS configured as μ∈{0,1,2,3}

[0175] In some embodiments, the indication signaling can indicate r16monitoringcapability, whereby the maximum number of PDCCH candidates and / or the maximum number of non-overlapping CCEs that the terminal can support can be defined based on a time span. For example, based on the configuration of the search space on the currently active BWP, the terminal counts the number of configured PDCCH candidates and / or the number of non-overlapping CCEs within a specific time span and determines whether this number exceeds the maximum number that the terminal can support. In some embodiments, this maximum number can be based on the following Table 2A and...

[0176] Table 2B Definitions:

[0177]

[0178] Table 2A: Maximum number of PDCCH candidates monitored within a time span for a single serving cell and for a DL BWP with SCS configured as μ∈{0,1}, for a combination (X,Y).

[0179]

[0180] Table 2B: Maximum number of non-overlapping CCEs within a time span for a single serving cell and for a DL BWP with SCS configured as μ∈{0,1}, for a combination (X,Y).

[0181] In some embodiments, in Tables 2A and 2B, X is the minimum symbol interval between the first OFDM symbols corresponding to two consecutive time spans, and Y is the maximum number of symbols for a single time span.

[0182] In some embodiments, the indication signaling can indicate r17monitoringcapability, whereby the maximum number of PDCCH candidates and / or the maximum number of non-overlapping CCEs that the terminal can support can be defined based on a time window consisting of Xs time slots. For example, based on the configuration of the search space on the currently active BWP, the terminal counts the number of configured PDCCH candidates and / or the number of non-overlapping CCEs within a specific time window consisting of Xs time slots and determines whether the number exceeds the maximum number that the terminal can support. In some embodiments, the maximum number can be defined based on the following Tables 3A and 3B:

[0183]

[0184] Table 3A: Maximum number of PDCCH candidates monitored per Xs time window for a single serving cell, for a DL BWP with SCS configured as μ∈{5,6}, and for a combination (X,Y).

[0185]

[0186] Table 3B: Maximum number of non-overlapping CCEs per Xs time window for a single serving cell, for a DL BWP with SCS configured as μ∈{5,6}, and for a combination (X,Y).

[0187] In some embodiments, Xs represents the number of consecutive time slots in Tables 3A and 3B. A time window consisting of Xs time slots can be composed of consecutive, non-overlapping time slots. The first Xs time window can start from the beginning position within a subframe. In some embodiments, Ys represents the time slots within a time window consisting of Xs time slots in Tables 3A and 3B. The PDCCH temporal resources for blind detection of the terminal are within a time window consisting of Ys time slots. Since a time window consisting of Ys time slots is within a time window consisting of Xs time slots, it can also be referred to as a sub-time window.

[0188] As communication technologies are applied in increasingly widespread scenarios, the types of terminals accessing communication networks are also increasing. These different types of terminals may have different capabilities. For example, the terminal capabilities related to blind detection may differ between different types of terminals.

[0189] Therefore, how to implement blind detection for terminals with differentiated terminal capabilities is a technical problem that urgently needs to be solved.

[0190] Figure 2 This is an interactive schematic diagram of a communication method provided according to an embodiment of this disclosure. The communication method involved in this embodiment can be applied to a communication system 100. Figure 2As shown, the communication method of this embodiment includes steps S201 to S208.

[0191] In step S201, terminal 101 determines terminal capabilities.

[0192] In some embodiments, terminal 101 may determine terminal capabilities related to PDCCH reception. In some embodiments, the terminal capabilities determined by terminal 101 may be the terminal 101's support capabilities for PDCCH reception.

[0193] In some embodiments, step S201 may include: terminal 101 acquiring terminal capabilities of the terminal and / or terminal capabilities of the device type to which the terminal belongs.

[0194] In some embodiments, the terminal capabilities of terminal 101 may be related to the UE capabilities of terminal 101. For example, UE capabilities may include at least one of the following: a first capability, a second capability, a third capability, and a fourth capability. In some embodiments, the terminal capabilities of terminal 101 may include at least one of the following: supporting capabilities related to the first capability, supporting capabilities related to the second capability, supporting capabilities related to the third capability, and supporting capabilities related to the fourth capability.

[0195] In some embodiments, terminal 101 may have support capabilities related to the first capability. In some embodiments, terminal 101's support capability for PDCCH reception may be related to the first capability. In some embodiments, the terminal capability of terminal 101 may include the terminal 101's support capability for PDCCH reception that supports the first capability. In some embodiments, terminal 101 may have characteristics related to the first capability. In some embodiments, characteristics related to the first capability may include ultra-high reliability, ultra-low latency, high stability, etc. In one example, reliability can be measured by the success rate of data packet transmission in communication. For example, ultra-high reliability may refer to a data packet transmission success rate greater than or equal to 99.999% or higher. In one example, latency can be measured by the end-to-end delay in communication. For example, ultra-low latency may refer to an end-to-end delay less than or equal to 1 millisecond. For example, communication performance can be guaranteed under conditions of mobility, interference, network congestion, etc. In one example, stability can be measured by the bit error rate in communication. For example, the bit error rate of the data transmission rate may be less than 10⁻⁵. In one example, the first capability may be a capability possessed by a URLLC type terminal; in other words, a terminal supporting the first capability may be a terminal supporting URLC characteristics. For example, the terminal capabilities of terminal 101 may include support capabilities related to URLLC.

[0196] In some embodiments, terminal 101 may have support capabilities related to the second capability. In some embodiments, terminal 101's support capability for PDCCH reception may be related to the second capability. In some embodiments, the terminal capability of terminal 101 may include the terminal 101's support capability for PDCCH reception that supports the second capability. In some embodiments, terminal 101 may have characteristics related to the second capability. In some embodiments, characteristics related to the second capability may include high frequency, large bandwidth, high spectral efficiency, etc. In one example, high frequency can be measured by a frequency band (i.e., a frequency range). For example, the frequency band related to the second capability may be a millimeter-wave band, a terahertz band, etc. For example, high frequency may refer to the lowest frequency of the frequency band being greater than or equal to 52.6 GHz. It is understood that the frequency band related to the second capability may also be in other frequency ranges, and this disclosure does not specifically limit this. In one example, large bandwidth may refer to a frequency band bandwidth greater than or equal to 100 MHz, or even greater than or equal to 1 GHz. In one example, spectral efficiency can be measured by the number of bits transmitted per unit bandwidth. For example, high spectral efficiency may refer to a spectral efficiency greater than or equal to 10 bps / Hz (i.e., bits per second per hertz). In one example, the second capability may be a capability possessed by a terminal that supports high-frequency communication; in other words, a terminal that supports the second capability may be a terminal that supports the characteristics of high-frequency communication. For example, the terminal capabilities of terminal 101 may include support capabilities related to high-frequency communication.

[0197] In some embodiments, terminal 101 may have support capabilities related to a third capability. In some embodiments, terminal 101's support capability for PDCCH reception may be related to a third capability. In some embodiments, the terminal capabilities of terminal 101 may include the terminal 101's support capability for PDCCH reception that supports a third capability. In some embodiments, the terminal may have characteristics related to a third capability. In some embodiments, characteristics related to a third capability may include IoT communication technology, low power consumption, wide coverage, low cost, etc. In one example, power consumption can be measured by battery life. For example, low power consumption may refer to a device's battery life exceeding 5 years. In one example, power consumption can be measured by the magnitude of the operating current. For example, low power consumption may refer to a device's operating current being less than 30μA, less than 5μA, or even less than 1.8μA, etc. In one example, coverage can be measured by communication distance. For example, wide coverage may refer to a communication distance greater than 1 kilometer. In one example, low cost may refer to a device cost less than or below a specific price, such as $10. For example, a terminal with third capabilities may have low processing power but relatively low latency requirements. In one example, the third capability can be a capability possessed by an LPWA-type terminal; in other words, a terminal supporting the third capability can be a terminal that supports LPWA features. For example, the terminal capabilities of terminal 101 can include LPWA-related support capabilities.

[0248] In some embodiments, the PDCCH budget is a budget within a specific resource range. This resource range can be determined by a first constraint. For example, the first constraint can be used to determine the resource range to which the PDCCH budget targets. In other words, the counting of PDCCH receptions corresponding to the PDCCH budget is performed within the resource range determined by the first constraint.

[0249] In some embodiments, the PDCCH budget may be determined based on a first constraint. In some embodiments, network device 102 may take the first constraint into account when determining the PDCCH budget.

[0251] In some embodiments, the first constraint may include at least one of the following: a first resource and a first condition.

[0252] In some embodiments, the PDCCH budget determined by network device 102 may be for a first resource. In some embodiments, the PDCCH budget may be used to limit PDCCH reception within the resource range of the first resource. In one example, the PDCCH budget may limit the number of PDCCH candidates supported by terminal 101 within the resource range of the first resource. In another example, the PDCCH budget may limit the number of CCEs supported by terminal 101 within the resource range of the first resource.

[0253] In some embodiments, the first resource may include at least one of the following: frequency domain resources, time domain resources, and logical resources.

[0254] In some embodiments, the frequency domain resources in the first resource can be resources based on band, carrier, bandwidth part (BWP), etc. In some embodiments, the frequency domain resources in the first resource may include at least one of the following: band, carrier, and BWP. In some embodiments, the frequency domain resources in the first resource may include the active BWP where terminal 101 is located. For example, the frequency domain resources in the first resource may include the active BWP where terminal 101 is located within the serving cell. In some embodiments, the frequency domain resources in the first resource may include the BWP configured corresponding to terminal 101. For example, the frequency domain resources in the first resource may include the BWP configured for terminal 101 within the serving cell.

[0255] In some embodiments, the time-domain resources in the first resource can be resources based on frames, subframes, time slots, sub-time slots, symbols, time spans, etc. In some embodiments, the time-domain resources in the first resource can include at least one of the following: frames, subframes, time slots, sub-time slots, symbols, and time spans. In some embodiments, the time-domain resources in the first resource can be resources based on time spans. In one example, a time span can include the time-domain resources continuously occupied by terminal 101 for blind detection of the PDCCH. For example, a time span as a first resource can include one or more symbols. In one example, the time-domain resources in the first resource can include the validity period of specific logical resources. For example, the time-domain resources in the first resource can include the validity period of specific cells and / or primary cell groups and / or secondary cell groups. In one example, the time-domain resources in the first resource can include the validity period of specific frequency-domain resources. For example, the time-domain resources in the first resource can include the validity period of specific frequency bands and / or carriers and / or BWPs. For example, the time-domain resources in the first resource can include the validity period for activating a BWP.

[0256] In some embodiments, the time-domain resources under the first constraint may be determined by at least one of the following: the maximum number of symbols for a time span; the minimum number of symbols between the first symbols of two consecutive time spans; the minimum number of time slots between two consecutive time spans; and the number of time slots in a time window.

[0257] In some embodiments, the temporal resources in the first resource can be determined by the maximum number of symbols sustained over a time span and the minimum number of symbols between the first symbols in two consecutive time spans. In one example, the temporal resources corresponding to the first resource can be determined based on (X, Y), where X is the minimum symbol interval between the first OFDM symbols in two consecutive time spans, and Y is the maximum number of symbols sustained over a time span. In one example, both X and Y are positive integers.

[0258] In some embodiments, the temporal resources in the first resource can be determined by the number of time slots in a time window. In one example, the temporal resources corresponding to the first resource can be determined based on (Xs, Ys), where Xs and Ys are both the number of consecutive time slots. For example, Xs is the number of time slots in a time window, i.e., Xs non-overlapping time slots can constitute a time window. For example, Ys is the number of time slots in a time window. The time window consisting of Ys time slots is located within the time window consisting of Xs time slots and is used to listen to the PDCCH. In other words, the terminal 101 can perform PDCCH listening in the time window consisting of Ys time slots (i.e., a sub-time window) within the time window consisting of Xs time slots. In one example, Xs and Ys are both positive integers. In some embodiments, the time window consisting of Xs time slots can start from the beginning position of a subframe.

[0259] In some embodiments, the temporal resources in the first resource can be determined by the minimum number of small slots between two consecutive time spans and the maximum number of symbols for a time span. In one example, the temporal resources corresponding to the first resource can be determined based on (Xz, Yz), where Xz is the minimum number of small slots between two consecutive time spans and Yz is the maximum number of symbols for a time span. In one example, both Xz and Yz are positive integers.

[0260] In some embodiments, the temporal resources in the first resource can be determined by the minimum number of time slots between two consecutive time spans and the number of time slots in a time window. In one example, the temporal resources corresponding to the first resource can be determined based on (Xz, Yz), where Xz is the minimum number of time slots between two consecutive time spans and Yz is the number of time slots in a time window. In one example, both Xz and Yz are positive integers. In some embodiments, the minimum number of time slots Xz between two consecutive time spans can be related to the storage capacity of terminal 101. For example, the stronger the storage capacity of terminal 101, the smaller the minimum number of time slots between two consecutive time spans can be. In some embodiments, the counting of PDCCH candidates and / or CCEs by the terminal can be performed based on a time window consisting of Yz time slots. In some embodiments, the starting position of the time window consisting of Yz time slots can be determined based on a reference resource. For example, the starting position of the time window consisting of Yz time slots can be the starting position of the reference resource. For example, the starting position of the time window consisting of Yz time slots can have an offset relative to the starting position of the reference resource. In one example, the reference resource can be located at the beginning of a subframe or at the beginning of a frame.

[0261] It should be noted that one or more time slots within a time window can be consecutive time slots in the time domain. A time window consisting of one or more consecutive time slots can also be called a time slot group. Of course, a time window can also be composed of one or more other time domain units, such as frames, subframes, sub-time slots, and symbols.

[0262] In some embodiments, the frequency domain resources in the first resource may include downlink BWPs. For example, the frequency domain resources in the first resource may include an active downlink BWP. For example, the frequency domain resources in the first resource may include one or more BWPs configured within the cell.

[0263] In some embodiments, the first resource may include logical resources. In some embodiments, the logical resources in the first resource may be resources based on cells, master cell groups (MCGs), secondary cell groups (SCGs), etc. In some embodiments, the logical resources in the first resource may include at least one of the following: a cell, a master cell group, or a secondary cell group. In some embodiments, the logical resources in the first resource may include a serving cell. In some embodiments, a master cell group may include a primary cell (PCell) and / or at least one secondary cell (SCell). In some embodiments, a secondary cell group may include a primary secondary cell (PSCell) and / or at least one secondary cell.

[0264] In some embodiments, the PDCCH budget determined by network device 102 may satisfy a first condition. In some embodiments, the PDCCH budget may be used to limit PDCCH reception that satisfies the first condition.

[0265] In some embodiments, the first condition may include at least one of the following: first RNTI scrambling, minimum number of time units between two consecutive time spans, number of time units for the duration of a time span, and SCS.

[0266] In some embodiments, the first condition may include scrambling with a first RNTI. In some embodiments, the first condition may include scrambling the DCI with a first RNTI. In some embodiments, the first RNTI may include at least one of the following: C-RNTI, MCS-C-RNTI (modulation and coding scheme C-RNTI), SP-CSI-RNTI (semi-persistent CSI-RNTI), SFI-RNTI (slot format indicator RNTI), TPC-PUSCH-RNTI (transmit power control PUSCH-RNTI), TPC-PUCCH-RNTI, TPC-SRS-RNTI, CI-RNTI (cancellation indicator), NES-RNTI (non-exclusive spectrum), SI-RNTI, G-RNTI (group RNTI), and P-RNTI. It is understood that the DCI may also be scrambled with other RNTIs, and this disclosure does not specifically limit this.

[0267] In some embodiments, the first condition may include the minimum number of time units between two consecutive time spans. In some embodiments, the number of time units between two consecutive time spans in the time domain may be associated with the density of time spans. In some embodiments, the larger the number of time units between them, the smaller the density of time spans distributed in the time domain; the smaller the number of time units between them, the larger the density of time spans distributed in the time domain.

[0268] In some embodiments, the first condition may include the number of time units that a time span lasts. In one example, a time span may occupy one or more time units.

[0269] It should be noted that the above time units can be at least one of the following: frame, subframe, time slot, sub-time slot, symbol.

[0270] In some embodiments, the first condition may include the SCS. In some embodiments, the SCS in the first condition may include at least one of the following: 15kHz, 30kHz, 60kHz, 120kHz, and 240kHz. In some embodiments, the size of the SCS is related to the size of the time slot. For example, a larger SCS results in a smaller time slot length; a smaller SCS results in a larger time slot length. In some embodiments, the size of the SCS is related to the resource block bandwidth. For example, a larger SCS results in a larger resource block bandwidth, a smaller number of resource blocks within the band, and a reduced CCE capacity; a smaller SCS results in a smaller resource block bandwidth, a larger number of resource blocks within the band, and an increased CCE capacity.

[0271] In some embodiments, the PDCCH budget determined by network device 102 may be obtained from other network devices. In some embodiments, network device 102 may receive the PDCCH budget for terminal 101's PDCCH reception provided by another network device. For example, network device 102 may receive the PDCCH budget provided by a core network device. In this case, network device 102 may determine the PDCCH budget provided by another network device as the PDCCH budget for terminal 101's PDCCH reception.

[0272] In step S204, network device 102 sends instruction information to terminal 101.

In some embodiments, network device 102 may send indication information to terminal 101, which may indicate the PDCCH budget provided by network device 102.

[0276] In some embodiments, network device 102 can determine indication information corresponding to the PDCCH budget based on a second mapping relationship. In some embodiments, the second mapping relationship can be determined by network device 102 according to a predefined definition. For example, network device 102 can determine the second mapping relationship based on a local configuration.

In some embodiments, the PDCCH budget may be used to limit PDCCH reception within the resource range of the first resource. In one example, the PDCCH budget may limit the number of PDCCH candidates supported by terminal 101 within the resource range of the first resource. In another example, the PDCCH budget may limit the number of CCEs supported by terminal 101 within the resource range of the first resource.

[0327] In some embodiments, the first resource may include at least one of the following: frequency domain resources, time domain resources, and logical resources.

[0328] In some embodiments, the frequency domain resources in the first resource can be resources based on frequency bands, carriers, BWPs, etc. In some embodiments, the frequency domain resources in the first resource may include at least one of the following: frequency band, carrier, and BWP. In some embodiments, the frequency domain resources in the first resource may include the active BWP where terminal 101 is located.

In some embodiments, the frequency domain resources in the first resource may include the BWP configured corresponding to terminal 101. For example, the frequency domain resources in the first resource may include the BWP configured for terminal 101 within the serving cell.

[0329] In some embodiments, the time-domain resources in the first resource can be resources based on frames, subframes, time slots, sub-time slots, symbols, time spans, etc. In some embodiments, the time-domain resources in the first resource can include at least one of the following: frames, subframes, time slots, sub-time slots, symbols, and time spans. In some embodiments, the time-domain resources in the first resource can be resources based on time spans. In one example, a time span can include the time-domain resources continuously occupied by terminal 101 for blind detection of the PDCCH. For example, a time span as a first resource can include one or more symbols. In one example, the time-domain resources in the first resource can include the validity period of specific logical resources. For example, the time-domain resources in the first resource can include the validity period of specific cells and / or primary cell groups and / or secondary cell groups. In one example, the time-domain resources in the first resource can include the validity period of specific frequency-domain resources. For example, the time-domain resources in the first resource can include the validity period of specific frequency bands and / or carriers and / or BWPs. For example, the time-domain resources in the first resource can include the validity period for activating a BWP.

[0330] In some embodiments, the time-domain resources under the first constraint may be determined by at least one of the following: the maximum number of symbols for a time span; the minimum number of symbols between the first symbols of two consecutive time spans; the minimum number of time slots between two consecutive time spans; and the number of time slots in a time window.

[0331] In some embodiments, the temporal resources in the first resource can be determined by the maximum number of symbols sustained over a time span and the minimum number of symbols between the first symbols in two consecutive time spans. In one example, the temporal resources corresponding to the first resource can be determined based on (X, Y), where X is the minimum symbol interval between the first OFDM symbols in two consecutive time spans, and Y is the maximum number of symbols sustained over a time span. In one example, both X and Y are positive integers.

[0332] In some embodiments, the temporal resources in the first resource can be determined by the number of time slots in a time window. In one example, the temporal resources corresponding to the first resource can be determined based on (Xs, Ys), where Xs and Ys are both the number of consecutive time slots. For example, Xs is the number of time slots in a time window, i.e., Xs non-overlapping time slots can constitute a time window. For example, Ys is the number of time slots in a time window. The time window consisting of Ys time slots is located within the time window consisting of Xs time slots and is used to listen to the PDCCH. In other words, the terminal 101 can perform PDCCH listening in the time window consisting of Ys time slots (i.e., a sub-time window) within the time window consisting of Xs time slots. In one example, Xs and Ys are both positive integers. In some embodiments, the time window consisting of Xs time slots can start from the beginning position of a subframe.

[0333] In some embodiments, the temporal resources in the first resource can be determined by the minimum number of small slots between two consecutive time spans and the maximum number of symbols for a time span. In one example, the temporal resources corresponding to the first resource can be determined based on (Xz, Yz), where Xz is the minimum number of small slots between two consecutive time spans and Yz is the maximum number of symbols for a time span. In one example, both Xz and Yz are positive integers.

[0334] In some embodiments, the temporal resources in the first resource can be determined by the minimum number of time slots between two consecutive time spans and the number of time slots in a time window. In one example, the temporal resources corresponding to the first resource can be determined based on (Xz, Yz), where Xz is the minimum number of time slots between two consecutive time spans and Yz is the number of time slots in a time window. In one example, both Xz and Yz are positive integers. In some embodiments, the minimum number of time slots Xz between two consecutive time spans can be related to the storage capacity of terminal 101. For example, the stronger the storage capacity of terminal 101, the smaller the minimum number of time slots between two consecutive time spans can be. In some embodiments, the counting of PDCCH candidates and / or CCEs by the terminal can be performed based on a time window consisting of Yz time slots. In some embodiments, the starting position of the time window consisting of Yz time slots can be determined based on a reference resource. For example, the starting position of the time window consisting of Yz time slots can be the starting position of the reference resource. For example, the starting position of the time window consisting of Yz time slots can have an offset relative to the starting position of the reference resource. In one example, the reference resource can be located at the beginning of a subframe or at the beginning of a frame.

[0335] In some embodiments, the frequency domain resources in the first resource may include downlink BWPs.

In some embodiments, a secondary cell group may include primary and secondary cells and / or at least one secondary cell.

[0337] In some embodiments, the PDCCH budget determined by terminal 101 may satisfy a first condition. In some embodiments, the PDCCH budget may be used to limit PDCCH reception that satisfies the first condition.

[0338] In some embodiments, the first condition may include at least one of the following: logical resources, first RNTI scrambling, minimum number of time units between two consecutive time spans, number of time units for the duration of a time span, and SCS.

[0339] In some embodiments, the first condition may include scrambling with a first RNTI. In some embodiments, the first condition may include scrambling the DCI with a first RNTI. In some embodiments, the first RNTI may include at least one of the following: C-RNTI, MCS-C-RNTI, SP-CSI-RNTI, SFI-RNTI, TPC-PUSCH-RNTI, TPC-PUCCH-RNTI, TPC-SRS-RNTI, CI-RNTI, NES-RNTI, SI-RNTI, G-RNTI, and P-RNTI. It is understood that the first RNTI may also be other RNTIs, and this disclosure does not specifically limit them.

[0340] In some embodiments, the first condition may include the minimum number of time units between two consecutive time spans. In some embodiments, the number of time units between two consecutive time spans in the time domain may be associated with the density of time spans. In some embodiments, the larger the number of time units between them, the smaller the density of time spans distributed in the time domain; the smaller the number of time units between them, the larger the density of time spans distributed in the time domain.

[0341] In some embodiments, the first condition may include the number of time units that a time span lasts. In one example, a time span may occupy one or more time units.

[0342] It should be noted that the above time units can be at least one of the following: frame, subframe, time slot, sub-time slot, symbol.

[0343] In some embodiments, the first condition may include the SCS. In some embodiments, the SCS in the first condition may include at least one of the following: 15kHz, 30kHz, 60kHz, 120kHz, and 240kHz. In some embodiments, the size of the SCS is related to the size of the time slot. For example, a larger SCS results in a smaller time slot length; a smaller SCS results in a larger time slot length. In some embodiments, the size of the SCS is related to the resource block bandwidth. For example, a larger SCS results in a larger resource block bandwidth, a smaller number of resource blocks within the band, and a reduced CCE capacity; a smaller SCS results in a smaller resource block bandwidth, a larger number of resource blocks within the band, and an increased CCE capacity.

[0344] In some embodiments, where the first constraint includes the serving cell, the blind detection budget may include a first number of DCI sizes supported by terminal 101 within the serving cell during PDCCH reception. In some embodiments, where the first constraint includes the serving cell and first RNTI scrambling, a second number of DCI sizes scrambled by the first RNTI supported by terminal 101 within the serving cell during PDCCH reception.

[0345] In some embodiments, if the first information includes at least two of the terminal capabilities of terminal 101, the terminal capabilities of the device type to which terminal 101 belongs, and indication information, terminal 101 may consider this information simultaneously to determine the PDCCH budget.

[0346] In some embodiments, when the first information obtained by terminal 101 includes at least two of the terminal capabilities of terminal 101, the terminal capabilities of the device type to which terminal 101 belongs, and indication information, terminal 101 may prioritize these information when determining the PDCCH budget. In some embodiments, when the first information includes indication information, terminal 101 may prioritize the indication information when determining the PDCCH budget. For example, terminal 101 may prioritize using the PDCCH budget indicated by the indication information. In some embodiments, when indication information is not obtained, terminal 101 may determine the PDCCH budget based on its terminal capabilities, or terminal 101 may determine the PDCCH budget based on the set of device types to which terminal 101 belongs. It should be noted that the priority order among indication information, first capability information, and second capability information may be predefined or configured by a higher layer.

[0347] In some embodiments, under a first condition, the maximum number of PDCCH candidates supported by terminal 101 in PDCCH reception can be a first number. It is understood that the first number in different PDCCH budgets can be the same or different.

[0348] In some embodiments, under a first condition, the maximum number of CCEs supported by terminal 101 in PDCCH reception can be a second number. It is understood that the first number in different PDCCH budgets can be the same or different.

[0349] In one example, the time-domain resources in the first resource are per slot and the SCS can be 15kHz. The number of first and second resources in different PDCCH budgets in this case can be found in Table 4 below.

[0352] In some embodiments, the LPWA-enabled terminal 101 may have low capabilities and wide coverage. For example, the LPWA-enabled terminal 101 may have the following characteristics: low hardware processing capabilities, such as limited processing speed, supported bandwidth, and PDCCH processing capabilities; narrow bandwidth, such as a maximum supported bandwidth of 20MHz or 5MHz; and low caching capabilities.

[0353] In some embodiments, the maximum number of PDCCH candidates and / or the maximum number of non-overlapping CCEs that terminal 101 can support can be defined based on each time slot. In one example, the maximum number of PDCCH candidates that terminal 101 can support can be found in Table 5A below. In Table 5A, N1, N2, N3, and N4 are all positive integers. In one example, N1 can be less than or equal to 44. For example, N1 can be equal to 36. In one example, N2 can be less than or equal to 36. For example, N2 can be equal to 22.

[0369] In step S207, terminal 101 sends fourth information to network device 102.

[0370] In some embodiments, terminal 101 may send fourth information. In some embodiments, the fourth information may be sent by terminal 101, but is not limited thereto, and may also be sent by other entities.

[0371] In some embodiments, network device 102 may receive fourth information. In some embodiments, the fourth information may be received by network device 102, but is not limited thereto, and may also be received by other entities.

[0372] In some embodiments, when terminal 101 determines the PDCCH budget received by its PDCCH based on the indication information, terminal 101 may not expect the PDCCH budget indicated by the indication information to exceed the terminal capabilities associated with terminal 101. The terminal capabilities associated with terminal 101 may include the terminal capabilities of terminal 101 and / or the terminal capabilities corresponding to the set of device types to which terminal 101 belongs. In some embodiments, terminal 101 may not expect the PDCCH budget indicated by the indication information to exceed the terminal capabilities of terminal 101 and / or the terminal capabilities corresponding to the set of device types to which terminal 101 belongs.

[0373] In some embodiments, if the PDCCH budget indicated by the indication information exceeds the terminal capabilities associated with terminal 101, terminal 101 may perform a first operation. In some embodiments, the first operation may include at least one of the following: performing a blind check based on the PDCCH budget supported by terminal 101; determining that an error has occurred; and reporting the error.

[0374] In some embodiments, if the PDCCH budget indicated by the indication information exceeds the terminal capability associated with terminal 101, terminal 101 may determine that an error has occurred. In other words, terminal 101 may determine that an error case has occurred.

[0375] In some embodiments, terminal 101 may send a fourth message to network device 102 to report the error. In some embodiments, the fourth message may indicate that the PDCCH budget provided by network device 102 exceeds the terminal capabilities associated with terminal 101. In some embodiments, the fourth message may indicate that an error has occurred where the PDCCH budget provided by network device 102 exceeds the terminal capabilities associated with terminal 101.

[0376] In some embodiments, the fourth information may include an error code. This error code can be used to identify an error where the PDCCH budget provided by network device 102 exceeds the terminal capabilities associated with terminal 101.

[0377] In some embodiments, the network device 102, upon receiving the fourth information, may re-execute steps S203 and S204. The network device 102 may redetermine the PDCCH budget received by the terminal 101 and provide the redetermined PDCCH budget to the terminal 101 by sending an indication message. Accordingly, the terminal 101 may execute step S206 again. In some embodiments, steps S203, S204, and S206 may be executed once or multiple times until the PDCCH budget provided by the network device 102 is within the terminal capabilities associated with the terminal 101.

[0378] In some embodiments, while sending the fourth information, terminal 101 may also send third information to network device 102. By sending the third information, terminal 101 can again provide the first capability information and / or the second capability information to network device 102. This allows network device 102 to redetermine the PDCCH budget received by terminal 101. In some embodiments, the third and fourth information may be independent of each other and carried in the same message. In some embodiments, the third and fourth information may be independent of each other and carried in different messages. In some embodiments, the third information may be included in the fourth information.

[0379] In some embodiments, step S207 may not be performed. In some embodiments, if an error is determined to have occurred, terminal 101 may not send the fourth information, i.e., it may not report the error. In one example, terminal 101 may not perform any operation. In one example, terminal 101 may perform blind detection based on the PDCCH budget supported by terminal 101.

[0380] In step S208, terminal 101 performs PDCCH reception.

[0381] In some embodiments, after the terminal 101 determines the PDCCH budget, the terminal 101 may perform PDCCH reception based on the determined PDCCH budget.

[0382] In some embodiments, as the peer, network device 102 may perform PDCCH transmission based on the PDCCH budget. For example, network device 102 may perform PDCCH transmission based on the PDCCH budget determined in step S203.

[0383] In some embodiments, the PDCCH reception performed by terminal 101 may include at least one of the following operations: blind detection, hardware processing, and buffering.

[0384] In some embodiments, terminal 101 may perform blind detection based on a blind detection budget within a determined PDCCH budget. In one example, terminal 101 may perform blind detection based on the maximum number of PDCCH candidates supported by terminal 101 in PDCCH reception. For example, the number of PDCCH candidates satisfying a first constraint obtained during blind detection may be less than or equal to this maximum number. In another example, terminal 101 may perform blind detection based on the maximum number of CCEs supported by terminal 101 in PDCCH reception. For example, the number of CCEs satisfying a first constraint obtained during blind detection may be less than or equal to this maximum number.

[0385] In some embodiments, terminal 101 may perform hardware processing based on a processing budget within a determined PDCCH budget. In one example, terminal 101 may perform hardware processing based on the maximum number of PDCCH candidates supported by terminal 101 in PDCCH reception. For example, the number of PDCCH candidates satisfying a first constraint obtained during hardware processing may be less than or equal to this maximum number. In another example, terminal 101 may perform hardware processing based on the maximum number of CCEs supported by terminal 101 in PDCCH reception. For example, the number of CCEs satisfying a first constraint obtained during hardware processing may be less than or equal to this maximum number.

[0386] In some embodiments, terminal 101 may perform blind detection based on the cache budget in the determined PDCCH budget. In one example, terminal 101 may perform caching based on the maximum number of cached PDCCH candidates supported by terminal 101 in PDCCH reception. For example, the number of PDCCH candidates satisfying the first constraint obtained during caching may be less than or equal to this maximum number. In one example, terminal 101 may perform blind detection based on the maximum number of cached CCEs supported by terminal 101 in PDCCH reception. For example, the number of CCEs satisfying the first constraint obtained during caching may be less than or equal to this maximum number.

[0387] In some embodiments, by performing PDCCH reception, terminal 101 can obtain PDCCH candidates. The terminal can then parse the DCI from the PDCCH candidates.

[0557] For example, the terminal capabilities include at least one of the following:

[0558] From the base station's perspective, the base station reports the capabilities that the terminal can support, thereby determining the PDCCH capabilities that the terminal supports.

[0559] Taking the largest PDCCH candidate that the terminal corresponding to the PDCCH capability can blindly detect as an example, the PDCCH capability is based on the following definition:

[0572] In some embodiments, the temporal resources can be measured based on frames, subframes, time slots, sub-time slots, symbols, time spans, etc. They can also be measured based on a specific effective time, such as the activation time of the BWP. The time span refers to the temporal resources corresponding to the terminal blind detection PDCCH; for example, the temporal resources correspond to a consecutive number of OFDM symbols.

[0581] - The number of non-overlapping CCEs corresponding to the PDCCH candidates configured by the terminal within the first resource range shall not exceed the second number.

[0582] In some embodiments, the time-domain resource corresponding to the first resource is per time slot.

[0583] In some embodiments, the time-domain resource corresponding to the first resource is measured based on (X,Y), where X is the minimum symbol interval between the first OFDM symbols corresponding to two consecutive time spans, and Y is the maximum number of symbols that can last in a single time span.

Exemplarily, the starting position of the time slot group composed of Yz is determined based on a reference resource. Exemplarily, the reference resource is the subframe start position, but it can also be the frame start position; this invention does not limit this.

[0587] In some embodiments, the frequency domain resource corresponding to the first resource is a downlink BWP, such as a downlink active BWP, or multiple BWPs configured within the cell.

[0588] In some embodiments, based on the above analysis, the terminal counts the number of PDCCH candidates or the number of inactive CCEs corresponding to the first resource and / or the first condition.

[0589] In some embodiments, the first resource and / or the first condition are as defined above and will not be repeated here.

[0590] In some embodiments, the first quantity and the second quantity correspond to different values ​​based on different PDCCH capabilities.

[0591] In some embodiments, referring to Table 4, taking the time domain resource corresponding to the first resource as each time slot and SCS = 15KHz as an example, different PDCCH capabilities and the above-mentioned quantities are illustrated, but the present invention is not limited thereto.

[0592] Step 3:

[0602] In some embodiments, from the perspective of the base station, the base station determines the PDCCH capabilities supported by the terminal and sends an indication signaling to indicate the capabilities.

[0603] In some embodiments, taking the PDCCH candidate / non-overlapping CCE corresponding to the terminal blind detection of PDCCH capability as an example, the definition of PDCCH capability is similar to that of method 1, and will not be repeated here.

[0604] Step 3:

[0606] In some embodiments, the terminal performs blind detection of corresponding PDCCH candidates based on the above capabilities and parses the DCI, which will not be elaborated further in this invention.

[0607] Example 3:

[0608] In some embodiments, the terminal determines the corresponding PDCCH capability based on terminal capabilities and indication information. Specific implementation methods are shown below:

[0609] Step 1:

[0610] In some embodiments, the terminal determines the supported capabilities and reports the corresponding capabilities.

[0611] In some embodiments, from the perspective of the base station, the base station determines the capabilities that the terminal can support based on the above-mentioned capability reports; and sends indication information to indicate the corresponding PDCCH capabilities.

[0612] In some embodiments, the base station, based on the base station implementation, determines that the PDCCH capability indicated by the indication signaling is within the range of capabilities supported by the terminal.

[0613] In some embodiments, if the terminal receives an indication message indicating a PDCCH capability outside the terminal's capability range, the terminal considers this an error, or the terminal re-reports the corresponding capability. Alternatively, the terminal may fall back to a fallback capability within the terminal's supported capabilities, such as PDCCH capabilities supported by the base version, or mandatory terminal capabilities.

[0614] Step 2:

[0615] In some embodiments, the terminal receives indication information and determines the supported PDCCH capabilities based on the above correspondence.

[0616] In some embodiments, from the perspective of the base station, the base station determines the PDCCH capabilities supported by the terminal and sends an indication signaling to indicate the capabilities.

[0617] In some embodiments, taking the PDCCH candidate / non-overlapping CCE corresponding to the terminal blind detection of PDCCH capability as an example, the definition of PDCCH capability is similar to that of method 1, and will not be repeated here.

[0618] Step 3:

[0619] In some embodiments, the terminal determines the capabilities of supported PDCCH candidate / non-overlapping CCEs based on the supported PDCCH capabilities.

[0620] In some embodiments, the terminal performs blind detection of corresponding PDCCH candidates based on the above capabilities and parses the DCI, which will not be elaborated further in this invention.

[0621] Sub-example:

[0622] In some embodiments, based on the scheme corresponding to any one of Embodiments 1 to 3, for a terminal with specific capabilities, taking an LPWA terminal as an example, the PDCCH capabilities that this type of terminal can support are illustrated.

[0623] In some embodiments, LPWA is a low-capability wide-coverage terminal, which has the following characteristics:

[0624] - The hardware processing capabilities are relatively low, for example, the processing speed and supported bandwidth are limited, and the PDCCH processing capability is limited;

[0625] - Supports smaller bandwidths; for example, a maximum bandwidth of 20MHz or a maximum bandwidth of 5MHz.

[0626] - The terminal caching capability is low.

[0627] Based on the above analysis, LPWA has low blind detection capabilities. To ensure that the defined PDCCH capabilities meet the requirements of the LPWA terminal, one or more of the following methods may be used:

[0628] Method 1:

[0629] The maximum number of PDCCH candidate / non-repeating CCEs supported by the terminal is defined per time slot, and the maximum number is less than the existing definition, such as the number of PDCCH candidate / non-repeating CCEs defined in R15. For example, one possible definition is shown in Tables 5A and 5B.

[0630] In some embodiments, in Table 5A, N1 is less than or equal to 44, for example, N1 equals 36; N2 is less than or equal to 36, for example, N2 equals 22; N3 is less than or equal to 22, for example, N3 equals 20; N4 is less than or equal to 20, for example, N4 equals 20.

[0631] In some embodiments, in Table 5B, N1 is less than or equal to 56, for example, N1 equals 48, or N1 equals 56; N2 is less than or equal to 56, for example, N2 equals 48; N3 is less than or equal to 48, for example, N3 equals 32; N4 is less than or equal to 32, for example, N4 equals 32, or N4 equals 16.

[0632] Method 2:

[0633] The maximum number of PDCCH candidate / non-repeating CCEs per slot group supported by the terminal is defined, wherein the slot group contains more than one slot, for example, the slot group contains two slots. The maximum number can be equal to, greater than, or less than the existing definition. For example, the existing definition is the number of PDCCH candidate / non-repeating CCEs defined in R15. One possible definition is shown in Tables 6A and 6B.

[0634] In some embodiments, in Table 6A, N1 equals 44; N2 equals 36; N3 equals 22; N4 is less than or equal to 20, for example, N4 equals 20.

[0635] In some embodiments, in Table 6B, N1 equals 56; N2 equals 56, exemplarily, N3 equals 48, exemplarily, N4 equals 32.

[0636] Method 3:

[0637] The maximum number of PDCCH candidates / non-repeating CCEs supported by the terminal is defined based on (X, Y), where X is the minimum slot / symbol interval corresponding to two consecutive time spans, and Y is a slot group consisting of multiple slots. The terminal counts the number of corresponding PDCCH candidates / CCEs based on the slot group corresponding to Y. For example, one possible definition is shown in Table 7. In some embodiments, X and Y in Table 7 are exemplary values, and other values ​​can also be used; this invention does not limit this. The N... ij The value is a positive integer, and this invention does not impose any restrictions on it.

[0638] In some embodiments, on the terminal side, the terminal determines its supported PDCCH capabilities based on first information; and based on the capabilities, blindly detects and receives the corresponding PDCCH.

[0639] In some embodiments, the base station indicates or determines the PDCCH capability supported by the terminal based on first information; and transmits the corresponding PDCCH based on the capability.
