[0035] PDCCH and its detection capability determination

[0036] In a mobile communication system, the PDCCH sent by a network device carries downlink control information (DCI), which is used to indicate information such as the time-frequency resources of the physical downlink shared channel (PDSCH) or the physical uplink shared channel (PUSCH). The resource granularity of the PDCCH can be a non-overlapping control channel element (CCE). However, when the network device sends the PDCCH to the terminal device, it does not indicate to the terminal device the number and location of the CCEs occupied by the PDCCH, nor the transmitted DCI format. Therefore, the terminal device needs to detect the PDCCH candidate set in different search spaces to find its specific time-frequency resource location. This process is called blind detection. In addition, before performing blind detection, the terminal device also needs to perform blind channel estimation on the non-overlapping CCEs to facilitate subsequent blind detection.

[0037] In order to ensure that the number of detections required for the PDCCH configured by the network device is within the capabilities achieved by the terminal device, the NR protocol stipulates the PDCCH detection capability of the terminal device, which is intended to constrain the PDCCH configuration of the network device. When the number of blind detections or blind channel estimates required for the PDCCH configured by the network device exceeds the PDCCH detection capability of the terminal device, the terminal device stops detecting PDCCH on the remaining potential resources. For multi-carrier systems, the protocol requires that the PDCCH candidate resources configured by the network device on the secondary cell (SCell) do not exceed the PDCCH detection capability of the terminal device. The PDCCH candidate resources configured on the primary cell (PCell) may exceed the PDCCH detection capability of the terminal device, but in the case of exceeding the PDCCH detection capability, the terminal device stops detecting PDCCH on the remaining candidate resources.

[0038] For single carrier systems, the PDCCH detection capability can be achieved through and Agreement. and The specific values ​​of are shown in Table 1 and Table 2 below. In the related art, and It can be pre-configured in the terminal device.

[0039] Refers to the maximum number of monitored PDCCH candidates per slot and per serving cell for a single serving cell. The maximum number of blind detections by a terminal device on a carrier does not exceed The value of is related to μ (μ is determined based on the subcarrier spacing). For example, as shown in Table 1, when μ is 3, When the number of PDCCH blind detections exceeds the subcarrier spacing corresponding to When the terminal device stops detecting PDCCH on the remaining potential resources, the terminal device stops detecting PDCCH on the remaining potential resources. The number of PDCCH blind detections is related to the number of DCIs to be detected, the aggregation level (AL) and the size of the candidate set of PDCCHs in each aggregation level. For example, the network device configures 2 DCI formats (i.e., the number of DCIs to be detected is 2) and 2 aggregation levels for the terminal device. If the candidate position set size corresponding to aggregation level 1 of the 2 aggregation levels is 4, and the candidate position set size corresponding to aggregation level 2 is 8, the number of blind detections required by the terminal device is (4+8)*2=24.

[0040] Table 1: Maximum number of candidate PDCCHs detected in each time slot for a single serving cell

[0041] Refers to the maximum number of non-overlapped CCEs per slot and per serving cell for a single serving cell. The maximum number of blind channel estimates for non-overlapped CCEs on a single carrier by a terminal device does not exceed The value of is also related to μ. For example, as shown in Table 2, when μ is 3, is 32. When the number of blind channel estimations for non-overlapping CCEs exceeds the number corresponding to the subcarrier spacing When , the terminal device stops detecting PDCCH on the remaining potential resources. The number of blind channel estimations required for non-overlapping CCEs is related to the time-frequency range of the potential distribution of the PDCCH to be detected and the precoding granularity.

[0042] Table 2: Maximum number of non-overlapping CCEs in each time slot for a single serving cell

[0043] For multi-carrier systems, since the PDCCH detection capability cannot increase linearly with the increase in the number of carriers, the total PDCCH detection capability of the multi-carrier system is constrained by limiting the maximum number of carriers for PDCCH detection. The maximum number of carriers for PDCCH detection is only used to calculate the total PDCCH detection capability and does not limit the number of scheduled carriers. Specifically, for each scheduled carrier, the number of PDCCH blind detections does not exceed The number of blind channel estimations for non-overlapping CCEs does not exceed in, and See Tables 1 and 2 above. and The determination method is as follows:

[0044] in, The maximum number of carriers detected by the PDCCH reported by the terminal, is the number of carriers corresponding to the target subcarrier spacing (determined based on μ), is the total number of carriers, then Indicates the ratio of the number of carriers with the target subcarrier spacing to the total number of carriers.

[0045] According to the above description, in a multi-carrier system, the PDCCH detection capability of the terminal device for each scheduled carrier is determined by the above formula. However, the same determination method may not be fully applicable to different carriers in a multi-carrier system. Because the scheduling requirements of different carriers in a multi-carrier system may be different, resulting in different PDCCH detection requirements for different carriers. The scheduling requirements of carriers with large bandwidth may be greater, and the network equipment may also configure more corresponding PDCCHs for them, which may require more PDCCH detection. For example, the bandwidth of a virtual carrier (or logical carrier) aggregated by multiple physical carriers is equivalent to several times that of the physical carrier, and its scheduling requirements also increase accordingly. However, the above method for determining the PDCCH detection capability does not take into account the differences between different carriers. The PDCCH detection capability determined for carriers with large scheduling requirements may be insufficient, and the PDCCH detection capability determined for carriers with small scheduling requirements may be excessive, which will affect the transmission efficiency of the PDCCH.

[0046] Based on the above problems, the embodiments of the present application are described in detail below.

[0047] As shown in Figure 2, an embodiment of the present application provides a method for channel detection, which includes step 210. In step 210, the terminal device determines the PDCCH detection capability corresponding to the first carrier among multiple carriers based on one or more of the first parameter, the second parameter, and the third parameter.

[0048] In some implementations, the first carrier may be any scheduled carrier among multiple carriers.

[0049] In some implementations, the first carrier may be a physical carrier, for example, a carrier that an allocation operator can independently access.

[0050] In some other implementations, the first carrier may also be a virtual carrier, for example, a carrier composed of one or more physical carriers.

[0051] In some implementations, the PDCCH detection capability corresponding to the first carrier may refer to the maximum number of candidate PDCCHs for blind detection by the terminal device and / or the maximum number of non-overlapping CCEs for blind channel estimation.

[0052] In some other implementations, the PDCCH detection capability corresponding to the first carrier may refer to a maximum number of blind detections of PDCCHs and / or a maximum number of blind channel estimations of non-overlapping CCEs.

[0053] In some implementations, the first parameter represents a bandwidth size of the first carrier. Determining a PDCCH detection capability corresponding to a first carrier among multiple carriers based on the first parameter helps to meet scheduling requirements of the first carrier.

[0054] In some implementations, the second parameter represents an allocation coefficient of the PDCCH detection capability corresponding to the first carrier.

[0055] In some implementations, the second parameter may be determined based on configuration information of the network device. In some implementations, the configuration information of the network device may indicate a value of an allocation coefficient of the PDCCH detection capability corresponding to the first carrier. Furthermore, the configuration information of the network device may be carried in a radio resource control (RRC) message, a DCI, or a medium access control (MAC) control element (CE).

[0056] In some implementations, the network device may configure the second parameter based on its scheduling requirements, and its scheduling requirements may be determined based on one or more factors such as the bandwidth of the first carrier, network coverage, and interference coordination.

[0057] In the embodiment of the present application, determining the PDCCH detection capability corresponding to the first carrier among the multiple carriers based on the second parameter helps to match the requirements of the network device.

[0058] In some implementations, the third parameter represents the total capability of PDCCH detection corresponding to the target carrier among multiple carriers. The target carrier has the same carrier attributes as the first carrier, so the third parameter may represent the sum of the capabilities of PDCCH detection corresponding to the carriers having the same carrier attributes as the first carrier among the multiple carriers. The sum of the PDCCH detection capabilities here may refer to the sum of the maximum number of blind detections of PDCCH, and / or the sum of the maximum number of blind channel estimates of non-overlapping CCEs. The carrier attributes here may include one or more of the following: subcarrier spacing; PDCCH detection type; wherein the PDCCH detection type includes detection in units of time slots or detection in units of time spans.

[0059] In some implementations, the third parameter can be determined based on one or more of the following parameters: a fourth parameter; a fifth parameter; a sixth parameter; an eighth parameter; or a ninth parameter.

[0060] In some implementations, the fourth parameter is used to indicate the maximum number of carriers for PDCCH detection by the terminal device. The fourth parameter can be determined by the terminal device, and the upper limit of the PDCCH detection capability of the terminal device can be determined based on the fourth parameter.

[0061] In some implementations, the fifth parameter is used to indicate the maximum number of times a terminal device performs PDCCH detection on a single carrier, and the fifth parameter can be determined according to the communication protocol. For example, as shown in Table 3, the value of the fifth parameter can be determined according to the maximum number of candidate PDCCHs detected in each time slot for a single service cell specified in the communication protocol. For example, when μ is 0, the maximum number of candidate PDCCHs in each time slot for a single service cell is 44, and the maximum number of PDCCH detections performed by the terminal device on a single carrier is 44. For multiple carriers, the sum of the number of times the terminal device performs blind PDCCH detection on multiple carriers can be further determined based on the fifth parameter.

[0062] Table 3: Maximum number of candidate PDCCHs in each time slot of a single serving cell

[0063] In some implementations, the sixth parameter is used to indicate the maximum number of non-overlapping CCEs used for channel estimation on a single carrier, and the sixth parameter may also be determined according to the communication protocol. For example, as shown in Table 4, the value of the sixth parameter may be determined according to the maximum number of non-overlapping CCEs in each time slot for a single service cell as specified in the communication protocol. For example, when μ is 0, the maximum number of non-overlapping CCEs in each time slot for a single service cell is 56, and the maximum number of non-overlapping CCEs used for channel estimation on a single carrier is 56. For multiple carriers, the sum of the number of blind channel estimations of non-overlapping CCEs performed by the terminal device on multiple carriers may be further determined based on the sixth parameter.

[0064] Table 4: Maximum number of non-overlapping CCEs in each time slot of a single serving cell

[0065] In some implementations, the eighth parameter is used to indicate the number of multiple carriers. The number of multiple carriers can be determined based on the number of semi-statically configured carriers (including activated and inactivated ones), or based on the number of activated carriers.

[0066] In some implementations, the ninth parameter is used to indicate the number of target carriers among the multiple carriers. For example, the number of target carriers having the same subcarrier spacing as the first carrier. For another example, the number of target carriers having the same PDCCH detection type as the first carrier.

[0067] In some implementations, the third parameter may be determined based on the fourth parameter, the fifth parameter, the eighth parameter, and the ninth parameter. Further, the third parameter may be determined based on the fourth parameter, the fifth parameter, and the tenth parameter, and the tenth parameter may be determined based on the quotient of the ninth parameter and the eighth parameter. That is, the third parameter is determined based on the following formula: Wherein, N represents the fourth parameter, M represents the fifth parameter, n represents the eighth parameter, and k represents the ninth parameter. Represents the tenth parameter, Indicates rounding down. As an example, the target carrier is a carrier with the same subcarrier spacing, with Represents the third parameter, then the above It can also be expressed as the following formula (1).

[0068] in Represents the fourth parameter, which means the maximum number of carriers that the terminal device can perform PDCCH detection. Indicates the fifth parameter, which means the maximum number of times the terminal device performs PDCCH detection on a single carrier. It represents the ninth parameter, which means the number of target carriers in multiple carriers (the target carriers correspond to the same μ). It represents the eighth parameter, which means the number of multiple carriers. The tenth parameter represents the ratio of the number of target carriers to the number of multiple carriers. Therefore, the third parameter determined based on the fourth parameter, the fifth parameter, the eighth parameter, and the ninth parameter can represent the sum of the maximum number of blind detections of the PDCCH corresponding to the target carrier in the multiple carriers.

[0069] In other implementations, the third parameter may be determined based on the fourth parameter, the sixth parameter, the eighth parameter, and the ninth parameter. Further, the third parameter may be determined based on the fourth parameter, the sixth parameter, and the tenth parameter, and the tenth parameter may be determined based on the quotient of the ninth parameter and the eighth parameter. That is, the third parameter is determined based on the following formula: Wherein, N represents the fourth parameter, C represents the sixth parameter, n represents the eighth parameter, and k represents the ninth parameter. Represents the tenth parameter, Indicates rounding down.

[0070] As an example, the target carrier is a carrier with the same subcarrier spacing as Indicates the third parameter, the above It can also be expressed as the following formula (2).

[0071] in Represents the fourth parameter, which means the maximum number of carriers that the terminal device can perform PDCCH detection. It represents the sixth parameter, which means the maximum number of non-overlapping CCEs used for channel estimation on a single carrier. It represents the ninth parameter, which means the number of target carriers in multiple carriers (the target carriers correspond to the same μ). It represents the eighth parameter, which means the number of multiple carriers. represents the tenth parameter, which means the ratio of the number of target carriers to the number of multiple carriers. Therefore, the third parameter determined based on the fourth parameter, the sixth parameter, the eighth parameter, and the ninth parameter can represent the sum of the maximum number of blind channel estimates for non-overlapping CCEs corresponding to the target carriers in the multiple carriers.

[0072] In an embodiment of the present application, determining the PDCCH detection capability corresponding to the first carrier among multiple carriers based on the third parameter helps to avoid the PDCCH detection capability corresponding to the first carrier exceeding the total PDCCH detection capability of the terminal device.

[0073] To sum up, in the embodiment of the present application, the PDCCH detection capability corresponding to a single carrier can be determined based on factors such as the bandwidth size of a single carrier in multiple carriers, the allocation coefficient of the PDCCH detection capability corresponding to the single carrier, and the total capability of PDCCH detection corresponding to the target carrier, which helps to more reasonably allocate the PDCCH detection capability corresponding to each carrier in multiple carriers.

[0074] In some implementations, the PDCCH detection capability corresponding to the first carrier may further be determined based on one or more of the following: a fourth parameter, a fifth parameter, a sixth parameter, a seventh parameter, an eighth parameter, a ninth parameter, and an eleventh parameter. That is, the PDCCH detection capability corresponding to the first carrier may be determined based on one or more of the first parameter, the second parameter, the third parameter, the fourth parameter, the fifth parameter, the sixth parameter, the seventh parameter, the eighth parameter, the ninth parameter, and the eleventh parameter. In addition to the first parameter, the second parameter, and the third parameter, introducing more parameters helps to more reasonably determine the PDCCH detection capability corresponding to the first carrier.

[0075] In some implementations, the seventh parameter is used to indicate the total bandwidth of the multiple carriers. Based on the seventh parameter, the bandwidth ratio of the first carrier can be further determined, thereby reflecting the scheduling requirements of the first carrier.

[0076] In some implementations, the eleventh parameter indicates the total bandwidth of the target carrier. The target carrier may be a carrier with the same carrier attributes among multiple carriers, such as carriers with the same subcarrier spacing. Based on the eleventh parameter, the bandwidth ratio of the first carrier in the target carrier can be further determined, thereby reflecting the scheduling requirements of the first carrier in the target carrier.

[0077] The following describes in detail how an embodiment of the present application determines the PDCCH detection capability corresponding to the first carrier based on the above one or more parameters.

[0078] Example 1

[0079] In some implementations, the terminal device may determine the PDCCH detection capability corresponding to a first carrier among multiple carriers based on a first parameter.

[0080] In some implementations, the PDCCH detection capability corresponding to the first carrier may be determined based on the first parameter, the fourth parameter, the fifth parameter, and the seventh parameter.

[0081] Furthermore, the PDCCH detection capability corresponding to the first carrier can be determined based on a twelfth parameter, which can be determined based on the product of the fourth parameter, the fifth parameter, and the thirteenth parameter; wherein the thirteenth parameter is determined based on the quotient of the first parameter and the seventh parameter. That is, the twelfth parameter is determined based on the following formula: Among them, N represents the fourth parameter, M represents the fifth parameter, Indicates the seventh parameter, B j Represents the first parameter, represents the thirteenth parameter, i and j are both positive integers greater than or equal to 0 and less than n, n represents the eighth parameter, Σ represents the sum, Indicates rounding down.

Indicates the seventh parameter, which means the total bandwidth of multiple carriers. Represents the thirteenth parameter, which means the ratio of the bandwidth of the first carrier among the multiple carriers to the total bandwidth of the multiple carriers. The PDCCH detection capability of the first carrier determined based on the above formula can represent the maximum number of blind detections of the PDCCH on the first carrier, and the maximum number of blind detections of the PDCCH on the first carrier is proportional to the ratio of the bandwidth occupied by the first carrier among the multiple carriers, which is consistent with the scheduling requirements of the first carrier and helps to make full use of the PDCCH detection capability of the terminal device.

[0084] In some other implementations, the PDCCH detection capability corresponding to the first carrier may be determined based on the first parameter, the fourth parameter, the sixth parameter, and the seventh parameter.

[0085] Furthermore, the PDCCH detection capability corresponding to the first carrier can be determined based on a twelfth parameter, which can be determined based on the product of the fourth parameter, the sixth parameter, and the thirteenth parameter; wherein the thirteenth parameter is determined based on the quotient of the first parameter and the seventh parameter. That is, the twelfth parameter is determined based on the following formula: Wherein, N represents the fourth parameter, C represents the sixth parameter, Indicates the seventh parameter, B j Represents the first parameter, represents the thirteenth parameter, i and j are both positive integers greater than or equal to 0 and less than n, n represents the eighth parameter, Σ represents the sum, Indicates rounding down.

[0087] in, Represents the fourth parameter, which means the maximum number of carriers that the terminal device can perform PDCCH detection. Indicates the fifth parameter, which means the maximum number of non-overlapping CCEs used for channel estimation on a single carrier. j Indicates the first parameter, which means the bandwidth of the jth carrier, that is, the bandwidth of the first carrier. i represents the bandwidth of the i-th carrier, that is, the bandwidth of any carrier among multiple carriers.
