Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and more specifically, to a multi-carrier detection method, device, and processor-readable storage medium. Background Art

[0002] In the prior art, when a network node configures a PDCCH (Physical Downlink Control Channel) for a UE (User Equipment), it calculates the total number of BDs (Blind Detection) and non-overlapped CCEs (non-overlapped Control Channel Element) on the scheduled carrier. When PCell (Primary Cell) / PSCell (Primary Secondary Cell) have different SCSs (Sub-Carrier Spacings), the current mechanism will have the problem of repeated calculation of the carrier. Since there are two scheduled carriers, such as cell#1 and cell#2, cell#1 of the scheduled carrier is calculated once according to SCS#1, and cell#2 of the scheduled carrier is calculated once according to SCS#2; the scheduled carrier is calculated twice, resulting in the total number of BDs / CCEs that the UE actually needs to detect and monitor exceeding the UE's own capability limit.

[0133] In order to better understand and illustrate the solutions of the embodiments of the present disclosure, some technical terms involved in the embodiments of the present disclosure are briefly explained below.

[0134] In the current NR (New Radio) system, if the network side (network node) configures multiple carriers for the terminal (UE), the network side needs to calculate the total number of BD / CCEs based on the terminal capability, the number of configured carriers, the number of carriers under each SCS, and the BD / CCE capability limit of each time slot or time span of the terminal. Since in the Rel-15 / 16 version, a scheduled carrier has only one scheduled carrier, the total number of BD / CCEs on the corresponding scheduled carrier can be directly calculated based on the above parameters for a specific scheduled carrier. Specifically, take the calculation formulas (1) and (2) in Rel-15 as an example (Note: The idea and principle of Rel-16 are exactly the same, but M-TRP (Multiple-Transmission Reception Point) and Rel-16 PDCCH monitoring capability (physical downlink control channel monitoring capability) are taken into account).

[0135]

[0136]

[0137] Wherein, M is the total number of BDs on all scheduled carriers with the same SCS in a slot; C is the total number of non-overlapped CCEs on all scheduled carriers with the same SCS in a slot.

[0138] For each scheduled carrier, the total number of BD / CCEs that the terminal can detect does not exceed as well as

[0139] In Rel-16, different SCSs are allowed for the scheduling carrier and the scheduled carrier. In this case, the scheduled carrier is classified into the carrier group of the scheduling carrier for calculation, that is, the total number of BD / CCEs of the scheduled carrier is calculated according to the SCS of the scheduling carrier.

[0140] In the Rel-17 dynamic spectrum sharing project, research has been conducted on SCell scheduling PCell. The main idea is to schedule PCell through SCell, reduce the probability of PDCCH congestion, and improve the overall performance of the system. For the scheduled PCell, scheduling can be performed through the PDCCH sent on the SCell and the PDCCH sent on the PCell. Unlike the current mechanism, the NR PCell / PSCell that shares spectrum with the LTE (Long Term Evolution) cell can be scheduled through two cells. Moreover, the PCell / PSCell and the SCell that schedules the cell may have different SCSs. In this scenario, there is currently no clear solution for how to calculate the total number of BD / CCE on all carriers.

[0141] When the network configures PDCCH for the terminal, it first calculates the total number of BDs and non-overlapped CCEs on the scheduled carrier. Then, according to the capacity limit of BD and non-overlapped CCEs in each time slot on a single carrier, it determines the upper limit of BD or non-overlapped CCE that can be configured for each scheduled carrier.

[0142] When the PCell / PSCell is scheduled by two cells at the same time, if the scheduling carrier and the scheduled carrier have the same SCS, the current mechanism can be fully reused. That is, the maximum total number of BDs / non-overlapped CCEs allowed on the scheduling carrier is first calculated in the SCS carrier group of the scheduling carrier and the scheduled carrier, and then BDs / CCEs are allocated to the scheduled carrier on the scheduling carrier according to the total number limit.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0173] Step S102: detecting downlink control channels according to a corresponding number of blind detection and non-overlapping control channel units.

[0174] In one embodiment, when the network side (network node) configures N scheduled carriers for a carrier, the terminal side (UE) determines how to calculate the total number of BDs and non-overlapped CCEs on all scheduled carriers by one of the following methods:

[0175] Method 1: Calculate the BD of the scheduled carrier and the total number of non-overlapped CCEs according to the SCS of one of the N scheduled carriers.

[0176] Wherein, N is an integer greater than or equal to 2; the scheduling carrier SCS used to calculate the BD and the total number of non-overlapped CCEs is determined by protocol pre-definition or RRC signaling (Radio Resource Control signaling) configuration.

[0177] For example, the scheduled carrier is scheduled through two scheduling carriers, and the SCS of the two scheduling carriers are 15kHz and 30kHz respectively. The SCell with a subcarrier spacing of 30kHz is determined as the reference carrier by protocol pre-definition or RRC signaling configuration. When calculating the BD of the scheduling carrier and the total number of non-overlapped CCEs, the scheduling carrier with a subcarrier spacing of 15kHz is treated as a carrier with a subcarrier spacing of 30kHz.

[0178] Method 2: The reference SCS of N scheduled carriers that schedule one carrier is configured through RRC signaling.

[0179] For example, the scheduled carrier is scheduled through two carriers, and the SCS of the two scheduled carriers are 15kHz and 60kHz respectively. Through RRC signaling configuration, the reference SCS of the two scheduled carriers is configured to be 30kHz. It is determined that both scheduled carriers are processed according to the 30kHz subcarrier spacing.

[0180] Method 3: Calculate the totalnumber of scheduled carriers with the same SCS according to the SCS of the N scheduled carriers respectively, and subtract a correction value from the calculated total number of BD / non-overlapped CCE, and the correction values ​​for BD and non-overlapped CCE are independent of each other. The correction value is a value configured by RRC signaling; or, the correction value is a value predefined by the protocol; or, the correction value is determined according to the capabilities reported by the terminal.

[0181] Method 4: The total number of BD / non-overlapped CCEs total number #1, total number #2, ..., total number N is calculated according to the SCS of the N scheduled carriers, and the final total number of BD / non-overlapped CCEs is determined as follows:

[0182] Min(total number#1,total number#2,…,total number N), or

[0183] Max(total number#1,total number#2,…,total number N), or

[0184]

[0185] Method 5: Calculate the total number of BD / non-overlapped CCEs total number #1, total number #2, ..., total number N according to the SCS of the N scheduled carriers, and determine the maximum number of BD / non-overlapped CCEs on the scheduled carriers according to the following method:

[0186] Step 1: For the carrier group with SCS#n, determine that the maximum number of BD / non-overlapped CCEs of the scheduled carrier on the scheduled carrier with SCS#n does not exceed min(M per-CC limit , M total ), n = 1, 2, ..., N. Among them, M per-CC limit is the capacity limit of each scheduled carrier, M total is the total number of third blind detections or the total number of third non-overlapping control channel units.

[0187] Step 2: For the scheduled carrier, the sum of the BDs or non-overlapped CCEs on all scheduled carriers shall not exceed the non-CA limit on the scheduled carrier, where the non-CA limit is the capacity limit of the scheduled carrier.

[0188] It should be noted that the total number in method 1, method 2, method 3, method 4 and method 5 is the total number of a slot or span.

[0215] Step S202: Send a downlink control channel according to a corresponding number of blind detection and non-overlapping control channel units.

[0216] In one embodiment, when the network side (network node) configures N scheduled carriers for a carrier, the network side determines how to calculate the total number of BDs and non-overlapped CCEs on the scheduled carrier by one of the following methods, and reaches a unified understanding with the terminal (UE):

[0217] Method 1: Calculate the BD of the scheduled carrier and the total number of non-overlapped CCEs according to the SCS of one of the N scheduled carriers.

[0218] Wherein, N is an integer greater than or equal to 2. The scheduled carrier SCS used to calculate the BD and the total number of non-overlapped CCEs is notified to the terminal by way of protocol pre-definition or RRC signaling configuration.

[0228] In an embodiment of the present application, when a network node configures at least two scheduling carriers for a carrier, the network node calculates the total number of blind detections and the total number of non-overlapping control channel units, and ensures that the total number of blind detections and the total number of non-overlapping control channel units do not exceed the UE capability.

[0229] The multi-carrier detection method of the above embodiment of the present application is comprehensively and thoroughly introduced through the following embodiments:

[0230] In Example 1 of the present application:

[0231] Multiple scheduling carriers are configured for the scheduled carrier. A typical example is the spectrum sharing scenario. Assume that the PCell of the NR UE and the LTE base station are deployed on the same frequency band. In order to avoid CRS (Cell Reference Signal) interference from the LTE system, the gNB needs to avoid the RE (Resource Element) occupied by the LTE CRS when sending the NR PDCCH. In order to ensure the flexibility of network deployment and scheduling, and reduce the PDCCH blockage on the NRPCell / PSCell, the SCell is allowed to schedule the PCell. At this time, the CSS (Common search space) or USS (UE-specific search space) on the PCell is still allowed to schedule this carrier, so that the PCell will have two scheduling carriers (N=2), namely the PCell and the SCell that schedules the PCell.

[0232] In one embodiment, a DSS (Dynamic Spectrum Sharing) scenario is taken as an example, that is, PCell / PSCell is scheduled by PCell / PSCell itself and SCell. Of course, this embodiment is only a specific application of the method described in this application, and this application does not exclude other application scenarios.

[0233] In one embodiment, it is assumed that the subcarrier spacing of PCell / PSCell is 15kHz, and the subcarrier spacing of SCell that schedules PCell / PSCell is 30kHz. At the same time, it is assumed that the network side has configured 5 carriers for the terminal, and the subcarrier spacings SCS of the 5 carriers are {PCell-15kHz, SCell#1-15kHz, SCell#2-30kHz, SCell#3-30kHz, SCell#4-30kHz} respectively. It is assumed that the number of supportable carriers reported by the terminal is 4. At the same time, it is assumed that in addition to being scheduled through the PDCCH sent on the current carrier (PCell), for example, scheduling the PDSCH (Physical Downlink ShareChannel) of the current carrier; PCell can also be scheduled through the PDCCH sent on SCell#2. In other words, PCell has two scheduling carriers, namely PCell with 15kHz SCS and SCell#2 with 30kHz SCS. As Figure 4 As shown, SCell#2 is the scheduled carrier of PCell and SCell#3, and SCell#1 and SCell#4 are scheduled by this carrier.

[0234] In one embodiment, Figure 4 As shown, the two scheduled carriers scheduling PCell have different SCSs, namely 15kHz and 30kHz. The total number of BD and non-overlapped CCE on the scheduled carrier is calculated by the following method:

[0235] When calculating the total BD and non-overlapped CCE on the scheduled carrier, the calculation is performed according to the SCS of the PCell (15kHz) or the SCell (30kHz) that schedules the PCell. The specific carrier's SCS is used to calculate the total BD and the number of non-overlapped CCEs. The base station and the terminal determine it in a predefined manner through the protocol, or the base station notifies through explicit RRC signaling, and this application does not limit it.

[0236] In one embodiment, the BD and the total number of non-overlapped CCEs on the scheduled carrier are calculated based on the subcarrier spacing of the SCell, that is, the scheduled PCell is treated as a 30kHz carrier. Further, at this time, the 15kHz subcarrier spacing carrier group includes one carrier {SCell#1}, and the 30kHz subcarrier spacing carrier group includes four carriers {PCell, SCell#2, SCell#3, SCell#4}. For each subcarrier group, the number of BD and non-overlapped CCE on the scheduled carrier with the corresponding SCS is calculated as follows. In this embodiment, the Rel-15 capable terminal is taken as an example. Of course, this method can be directly applied to multi-carrier scheduling scenarios of Rel-16 and subsequent versions.

[0237] In one embodiment, for a 15 kHz carrier, the BD and the total number of non-overlapped CCEs are calculated according to the following formulas:

[0238]

[0239]

[0240] For each scheduled carrier, the terminal does not expect blind detection to be more than Don't expect more than

[0241] For a 30kHz carrier, the total number of BDs and non-overlapped CCEs are calculated using the following formulas:

[0242]

[0243]

[0244] For each scheduled carrier, the terminal does not expect to blindly detect more than It is not expected to detect more than

[0245] in, The blind detection capability reported by the terminal. For SCS is 15×2 μ The number of carrier waves in kHz, is the maximum number of blind detections in each slot on each carrier, The maximum number of non-overlapped CCEs in each slot on each carrier.

[0246] For the scheduled PCell, according to the above calculation method, the base station and the terminal determine through a protocol predefined method, or the base station notifies through explicit RRC signaling, according to the 30kHz carrier, that the maximum number of BDs that can be monitored on the PCell and SCell#2 that schedule the PCell is not more than 36, and the maximum number of non-overlapped CCEs is not more than 56. When the base station configures the search space for the terminal, or the terminal side performs the dropping operation, it is performed according to the maximum 36 BDs and the maximum 56 CCEs.

[0247] In one embodiment, taking Rel-15 capability as an example, it can also be applied to carrier aggregation scenarios of Rel-16 capability carriers or subsequent evolved versions, that is, the BD / CCE limit on each carrier is defined in units such as span or MO.

[0248] In the second embodiment of the present application:

[0249] Multiple scheduling carriers are configured for the scheduled carrier. A typical example is the spectrum sharing scenario. Assume that the PCell of the NR UE and the LTE base station are deployed on the same frequency band. In order to avoid CRS interference from the LTE system, the gNB needs to avoid the RE occupied by the LTE CRS when sending NRPDCCH. In order to ensure the flexibility of network deployment and scheduling, and to reduce the PDCCH blockage on the NR PCell / PSCell, the SCell is allowed to schedule the PCell. At this time, the CSS or USS on the PCell is still allowed to schedule this carrier, so that the PCell will have two scheduling carriers, namely the PCell and the SCell that schedules the PCell.

[0250] In one embodiment, a dynamic spectrum sharing DSS scenario is taken as an example, that is, PCell / PSCell is scheduled by PCell / PSCell itself and SCell. Of course, this embodiment is only a specific application of the method described in this patent, and this patent does not exclude other application scenarios.

[0251] In one embodiment, it is assumed that the subcarrier spacing of the PCell / PSCell is 15kHz, and the subcarrier spacing of the SCell that schedules the PCell / PSCell is 60kHz. At the same time, it is assumed that the network side has configured 5 carriers for the terminal, and the SCS of the carriers are {PCell-15kHz, SCell#1-30kHz, SCell#2-60kHz, SCell#3-60kHz, SCell#4-60kHz}. It is assumed that the number of supportable carriers reported by the terminal is 4. At the same time, it is assumed that in addition to being scheduled through the PDCCH sent on the current carrier, for example, scheduling the PDSCH of the current carrier; the PCell can also be scheduled through the PDCCH sent on SCell#2. In other words, the PCell has two scheduling carriers, namely the PCell with a 15kHz SCS and the SCell#2 with a 60kHz SCS. Figure 5 As shown, SCell#2 is the scheduled carrier of PCell and SCell#2, SCell#4 schedules SCell#3 and SCell#4, and SCell#1 is scheduled by this carrier.

[0252] In one embodiment, Figure 5 As shown, at this time, the two scheduled carriers for scheduling PCell have different SCSs, namely 15kHz and 60kHz. In this embodiment, the total number of BD and non-overlapped CCE on the scheduled carrier is calculated by the following method:

[0253] The reference SCS of the N scheduled carriers that schedule one carrier is configured through RRC signaling.

[0254] In one embodiment, when calculating the total number of BDs and non-overlapped CCEs on the scheduled carrier, the SCS of the scheduled PCell and the SCell that schedules the PCell are regarded as the reference SCS configured above. In this embodiment, it is assumed that the reference SCS configured by the RRC signaling is 30kHz. At this time, the 30kHz subcarrier spacing carrier group includes three carriers {PCell, SCell#1, SCell#2}, and the 60kHz subcarrier spacing carrier group includes two carriers {SCell#3, SCell#4}. For each subcarrier group, the number of BDs and non-overlapped CCEs on the scheduled carrier with the corresponding SCS is calculated as follows. In this embodiment, the Rel-15 capable terminal is taken as an example. Of course, this method can be directly applied to multi-carrier scheduling scenarios of Rel-16 and subsequent versions.

[0255] For a 30kHz carrier, the total number of BDs and non-overlapped CCEs are calculated using the following formulas:

[0256]

[0257]

[0258] For each scheduled carrier, the terminal does not expect blind detection to be more than Don't expect more than

[0259] For a 60kHz carrier, the total number of BDs and non-overlapped CCEs are calculated using the following formulas:

[0260]

[0261]

[0262] For each scheduled carrier, the terminal does not expect to blindly detect more than It is not expected to detect more than

[0263] In the third embodiment of the present application:

[0264] This embodiment is described by taking the configuration described in Embodiment 1 as an example. The specific network side configuration and assumptions are described in Embodiment 1, and will not be described in detail in this embodiment.

[0265] In one embodiment, the total number of BDs and non-overlapped CCEs on the scheduled carrier is calculated by the following method:

[0266] The network side calculates the totalnumber on the scheduled carriers with the same SCS according to the SCS of the N scheduled carriers, and subtracts a correction value from the calculated total number of BD / non-overlapped CCEs.

[0267] In one embodiment, the BD and the total number of non-overlapped CCEs on the scheduled carrier are calculated according to the subcarrier spacing of the SCell and the subcarrier spacing of the PCell, respectively. Further, at this time, the 15kHz subcarrier spacing carrier group includes two carriers {PCell, SCell#1}, and the 30kHz subcarrier spacing carrier group includes four carriers {PCell, SCell#2, SCell#3, SCell#4} (Note: According to the current method, when the scheduled carrier and the scheduling carrier have different SCSs, the total BD / CCE number of the scheduled carrier is calculated according to the SCS of the scheduling carrier). For each subcarrier group, the number of BDs and non-overlapped CCEs on the scheduled carrier with the corresponding SCS is calculated as follows. In this embodiment, the Rel-15 capable terminal is taken as an example. Of course, this method can be directly applied to multi-carrier scheduling scenarios of Rel-16 and subsequent versions.

[0268] For a 15kHz carrier, the total number of BDs and non-overlapped CCEs are calculated using the following formulas:

[0273]

[0274] From the above calculation process, it can be seen that the scheduled PCell is actually calculated twice, that is, once according to the 15kHz subcarrier spacing and once according to the 30kHz subcarrier spacing.

[0275] In one embodiment, a correction value Δ is subtracted from the BD and the total number of non-overlapped CCEs calculated for 15kHz subcarrier spacing and / or 30kHz subcarrier spacing, and then compared with the terminal capability in each slot on each carrier. The correction value Δ can be determined according to the following method, which is not limited in this embodiment:

[0276] Determined by RRC signaling sent by the base station;

[0277] Alternatively, it is determined by a method predefined by the protocol;

[0278] Alternatively, it is determined by the capabilities reported by the terminal.

[0279] It should be noted that the correction value Δ can be applied to one or both of the two carrier groups. When both carrier groups need to be revised, the correction value Δ can be different, and this application does not impose any limitation on this.

[0280] In one embodiment, assuming that the correction value for BD is ΔBD=22, and the correction value for non-overlapped CCE is ΔCCE=28, and both are applied to two carrier groups at the same time, the total BD and the number of non-overlapped CCE after correction are as follows:

[0298] In one embodiment, the BD and the total number of non-overlapped CCEs on the scheduled carrier are calculated according to the subcarrier spacing of the SCell and the subcarrier spacing of the PCell, respectively. Further, at this time, the 15kHz subcarrier spacing carrier group includes two carriers {PCell, SCell#1}, and the 30kHz subcarrier spacing carrier group includes four carriers {PCell, SCell#2, SCell#3, SCell#4}; It should be noted that according to the current method, when the scheduled carrier and the scheduling carrier have different SCSs, the total BD / CCE number of the scheduled carrier is calculated according to the SCS of the scheduling carrier.
