Embodiments for Carrying Out the Invention

[0022] In the PDCCH blind detection process, the terminal first obtains the time-frequency domain information and aggregation level of the PDCCH according to the configuration of the control resource set (CORESET) and the search space, and then needs to determine the index of the CCE occupied by the PDCCH candidate in the corresponding search space set. Next, based on the mapping from the CCE index to the resource element group (REG) bundle, the position of the physical resource is determined, and then PDCCH blind detection is performed.

[0023] For the search space set s associated with CORESET p, calculate the index of the CCE occupied by the PDCCH candidate corresponding to the aggregation level L by the following formula.

Equation

Furthermore,

[0025] In related art, a single DCI format is used only to schedule a single cell, and the CIF is used to indicate the scheduled cell corresponding to a PDCCH candidate. Due to the reallocation of 4G spectrum, the fragmented frequency band available for 5G increases. To improve spectrum utilization, the CIF field needs to be redesigned by introducing an uplink channel and / or downlink channel mechanism that schedules multiple cells using a single DCI format. In this way, the method of calculating CCE indexes by referring to the CIF may no longer be applicable.

[0026] Based on this, in each embodiment of the present application, the first DCI can schedule the uplink channel and / or downlink channel of at least two cells simultaneously. For the first DCI that schedules the combination of the first cells, the terminal determines the index of the CCE occupied by the PDCCH candidate corresponding to the first DCI based on the carrier indication value configured by the network side for the combination of the first cells. In the above solution, the DCI can schedule the uplink channel and / or downlink channel of at least two cells simultaneously, and the terminal determines the index of the CCE occupied by the PDCCH candidate corresponding to the DCI based on the carrier indication value configured by the network side for each combination of cells that the DCI can schedule. In this way, in the cross-carrier scheduling scenario, the value of n for calculating the index of the CCE CI is a value configured by the network side and related to the combination of cells actually scheduled by the DCI. Since the value of n CI no longer refers to the value of the CIF, when a single DCI can schedule at least two cells simultaneously, the calculation of the CCE index is effectively realized, and the time-frequency resource occupied by the PDCCH candidate corresponding to the DCI is determined.

[0027] Hereinafter, the present application will be described in more detail with reference to the drawings and embodiments.

[0028] The embodiments of the present application provide a channel monitoring method applied to a terminal. As shown in FIG. 1, the channel monitoring method includes the following steps.

[0029] In step 101, based on the first carrier indication value, determine the index of the CCE occupied by the PDCCH candidate corresponding to the first DCI.

[0030] Here, the first DCI represents a DCI capable of simultaneously scheduling uplink channels and / or downlink channels of at least two cells, the first carrier indication value represents a carrier indication value configured by the network side for a combination of first cells, and the combination of the first cells is a combination of cells scheduled by the first DCI.

[0031] In a scenario where a single DCI simultaneously schedules uplink channels and / or downlink channels of at least two cells, the first DCI can schedule one or more cells simultaneously, and the one or more cells scheduled by the first DCI are correspondingly called a combination of one cell. For example, the first DCI can schedule three cells, namely cell #1, cell #2, and cell #3, simultaneously, and the cells actually scheduled by the first DCI each time may be one or more of the three cells. That is, the combinations of cells that the first DCI can schedule can include seven combinations of cells: (cell #1), (cell #2), (cell #3), (cell #1, cell #2), (cell #1, cell #3), (cell #2, cell #3), (cell #1, cell #2, cell #3). For each combination of cells that the first DCI can schedule, the network side configures a corresponding carrier indication value and transmits this carrier indication value to the terminal via downlink signaling. For example, this carrier indication value is transmitted to the terminal by carrying this carrier indication value in radio resource control (RRC) signaling or the first DCI, and the terminal calculates the index of the CCE occupied by the corresponding PDCCH candidate based on the carrier indication value configured by the network side for the combination of cells actually scheduled by the first DCI.

[0032] Here, the carrier indication value is n in the above formula CIIt can be understood as such, and thus, after the terminal determines the first carrier indication value corresponding to the combination of the first cells, it calculates the index of the CCE occupied by the PDCCH candidate corresponding to the first DCI based on the above formula, that is, it can determine the position of the CCE occupied by the PDCCH candidate corresponding to the first DCI. In this way, in the cross-carrier scheduling scenario, the calculation of the CCE index can be effectively realized, whereby the time-frequency resources occupied by the PDCCH candidate corresponding to the DCI that schedules multiple cells simultaneously can be determined.

[0033] In actual applications, for the combination of cells schedulable by the first DCI, the configuration of the carrier indication value by the network side may include, but is not limited to, the following several solutions.

[0034] Regarding Solution 1 In one embodiment, any combination of cells schedulable by the first DCI is composed of the first carrier indication value.

[0035] In Solution 1, regardless of the combination of cells actually scheduled by the first DCI, the network side configures (sets) the same first carrier indication value so that the terminal calculates the index of the CCE for determining the position of the CCE occupied by the PDCCH candidate. That is, the carrier indication values configured corresponding to each combination of cells are all the same, and the value of the carrier indication value has no relation to the CIF or the information dynamically indicating the scheduled cells. For example, the network side may configure it to n CI =0, or the value of n CI is used as the cell index during single-cell scheduling for n CIIt may be configured with a value different from the value of

Number

[0036] In actual applications, since the first carrier indication value is fixed, after the terminal accesses the base station, the base station may send the first carrier indication value to the terminal via RRC signaling, or the base station may send the first carrier indication value via media access control-control element (MAC-CE) signaling or DCI signaling. Although the actually scheduled cells may have different combinations, in Solution 1, since the CCE index is calculated based on the same carrier indication value, the number of PDCCH candidates is the same. In this way, determining the time-frequency resources occupied by the PDCCH candidates has a simple configuration method, low computational complexity, and is not affected by the information indicating the dynamically scheduled cells in the process of determining the time-frequency resources occupied by the PDCCH candidates. In particular, when the number of cells schedulable by a single DCI is large, using Solution 1 can prevent the computational complexity of the CCE index from being affected.

[0037] Furthermore, the network side can also configure different carrier indication values for different combinations of cells actually scheduled by the first DCI. In this case, the first carrier indication value is determined from the first parameter set, and the first parameter set includes at least two different carrier indication values configured by the network side.

[0038] Regarding Solution 2 In one embodiment, each carrier indication value in the first parameter set corresponds to a combination of cells schedulable by the first DCI respectively.

[0039] In this embodiment, the PDCCH candidates corresponding to each combination of schedulable cells occupy non-overlapping CCE indexes, and a plurality of different carrier indication values configured by the network side correspond one-to-one to each combination of schedulable cells. The terminal needs to select the carrier indication value corresponding to the actually scheduled cell combination from the plurality of different carrier indication values configured by the network side and calculate the CCE index. In Solution 2, when the combinations of schedulable cells are different, the terminal needs to monitor different PDCCH candidates. Since the PDCCH candidates corresponding to different cell combinations occupy non-overlapping CCE indexes, the number of PDCCH candidates corresponding to different cell combinations

Number

[0040] In actual applications, the first carrier indication value may be transmitted by the base station via MAC-CE signaling or DCI signaling.

[0041] Referring to the above example, if the combinations of schedulable cells are (Cell #1), (Cell #2), (Cell #3), (Cell #1, Cell #2), (Cell #1, Cell #3), (Cell #2, Cell #3), (Cell #1, Cell #2, Cell #3), the first parameter set configured correspondingly by the network side includes seven carrier indication values with different values, each corresponding to the above seven combinations of cells. In the PDCCH blind detection process, the terminal first determines the carrier indication value corresponding to the combination of cells actually scheduled from the first parameter set, and then calculates the index of the CCE based on the determined carrier indication value, thereby determining the index of the CCE occupied by the PDCCH candidate.

[0042] Solution 2 is more suitable than Solution 1 when configuring different PDCCH candidates for different combinations of schedulable cells, and when scheduling different combinations of cells, it is ensured that the PDCCH candidates corresponding thereto do not occupy overlapping CCEs as much as possible, thereby enabling flexible utilization of time-frequency resources. In contrast, Solution 1 is suitable when considering the monitoring ability of the terminal and the number of PDCCH candidates and the number of non-overlapping CCEs are limited during blind detection. In particular, when the maximum number of cells for which DCI is schedulable increases, the number of combinations of schedulable cells increases, and the PDCCH candidates corresponding to different combinations of cells need to occupy more overlapping CCEs. Otherwise, the blocking rate of the PDCCH may increase, and in this case, it is more reasonable to adopt Solution 1.

[0043] Regarding Solution 3 In one embodiment, each carrier indication value in the first parameter set corresponds to a combination of at least two cells for which the first DCI is schedulable, and the number of cells in the combination of cells configured with the same carrier indication value is the same.

[0044] In Solution 3, a plurality of different carrier indication values configured by the network side are the same as the carrier indication values configured for combinations of cells containing the same number of cells, that is, the carrier indication values corresponding to the combinations of cells actually scheduled are determined based on the number of cells in this combination of cells, and it can be understood that the number of carrier indication values in the first parameter set is the same as the maximum number of cells corresponding to the combination of cells. In this way, for different combinations of schedulable cells, the terminal can monitor the same or different PDCCH candidates.

[0045] In actual applications, the first carrier indication value may be transmitted by the base station via MAC-CE signaling or DCI signaling.

[0046] Also, after determining the index of the corresponding CCE based on the number of cells in the combination of cells, the combination of cells actually scheduled may be further determined based on relevant information. In one embodiment, the channel monitoring method further includes the step of determining the first combination of cells from at least two combinations of cells composed of the first carrier indication value based on the CIF or the first signaling.

[0047] Here, the first signaling is used to indicate the scheduled cells.

[0048] In actual applications, there may be a plurality of combinations of cells with the same corresponding carrier indication value. Here, when there are a plurality of combinations of cells corresponding to the determined carrier indication value, the combination of cells actually scheduled may be further determined from the plurality of combinations of cells via the CIF or the scheduled cell indication signaling.

[0049] Referring to the above example, if the combinations of schedulable cells are (Cell #1), (Cell #2), (Cell #3), (Cell #1, Cell #2), (Cell #1, Cell #3), (Cell #2, Cell #3), (Cell #1, Cell #2, Cell #3), each of these combinations of cells contains one, two, or three cells, and the network side constructs three carrier indication values corresponding to the number of cells in the combination of cells. For example, the carrier indication value with a value of 0 corresponds to the combinations of cells with one cell, that is, the three combinations of cells (Cell #1), (Cell #2), (Cell #3); the carrier indication value with a value of 1 corresponds to the combinations of cells with two cells, that is, the three combinations of cells (Cell #1, Cell #2), (Cell #1, Cell #3), (Cell #2, Cell #3); and the carrier indication value with a value of 2 corresponds to the combination of cells with three cells, that is, the combination of cells (Cell #1, Cell #2, Cell #3). In this way, the terminal can select some combinations of cells from the combinations of schedulable cells based on the number of cells corresponding to the first carrier indication value, and further determine the actually scheduled cells based on the 2-bit scheduled cell indication signaling.

[0050] Exemplarily, the correspondence between the carrier indication value, the scheduled cell indication signaling, and the actually scheduled cells is as shown in Table 1.

Table 1

[0051] In Solution 3, the value of the carrier indication value is determined based on the number of cells actually scheduled, resulting in less further division of time-frequency resources. Compared with Solution 1, time-frequency resources can be utilized more flexibly. Also, compared with Solution 2, the problem that the number of PDCCH candidates and the number of non-overlapping CCEs are limited can be avoided. Furthermore, by combining the carrier indication value and the scheduled cell indication signaling, the method for determining the actually scheduled cells can effectively reduce the size of the indication field information and save control overhead.

[0052] Regarding the above-mentioned Solution 2 and Solution 3, after the terminal accesses the base station and before the base station transmits the first DCI to the terminal, the base station needs to transmit the mapping relationship between different combinations of carrier indication values and different cells to the terminal. Furthermore, regarding Solution 3, the base station needs to transmit a one-to-one mapping relationship between different CIF values, different carrier indication values, and different combinations of cells to the terminal. After receiving the first carrier indication value, the terminal can determine the combination of cells actually scheduled by the first DCI based on the mapping relationship transmitted from the base station.

[0053] Correspondingly, the embodiments of the present application further provide a channel monitoring method, which is applied to a network device, such as a base station like a next-generation base station (gNB). As shown in FIG. 2, the channel monitoring method includes the following steps.

[0054] In step 201, at least one carrier indication value is configured.

[0055] Here, the at least one carrier indication value is used to determine the index of the CCE occupied by the PDCCH candidate corresponding to the first DCI, and the first DCI represents a DCI capable of simultaneously scheduling the uplink channels and / or downlink channels of at least two cells.

[0056] Here, in one embodiment, the step of configuring the at least one carrier indication value includes: configuring a first carrier indication value for any combination of cells schedulable by the first DCI.

[0057] In one embodiment, the step of configuring the at least one carrier indication value includes: including a step of configuring a first parameter set, wherein the first parameter set includes at least two different carrier indication values, and each carrier indication value respectively corresponds to at least one combination of cells schedulable by the first DCI.

[0058] In one embodiment, each carrier indication value in the first parameter set corresponds to at least two combinations of cells schedulable by the first DCI, and the number of cells in the combinations of cells corresponding to the same carrier indication value is the same.

[0059] For the related description of the channel monitoring method on the network device side, reference can be made to the embodiments of the channel monitoring method on the terminal side described above, and details will not be repeated here.

[0060] The above embodiments can effectively realize the calculation of the CCE index in the cross-carrier scheduling scenario, and can determine the time-frequency resources occupied by the PDCCH candidates of multiple cells simultaneously scheduled by the DCI without using a new CIF or new dynamic indication information. Furthermore, the above embodiments provide three specific configuration methods, which can be combined with specific scenarios in actual applications. For example, when the number of cells that can be scheduled by a single DCI is large, the configuration method of Solution 1 can be selected to avoid the excessive calculation complexity of the CCE index. To avoid occupying overlapping CCEs as much as possible, the configuration method of Solution 2 can be selected to realize flexible utilization of time-frequency resources. Furthermore, the configuration method of Solution 3 can be selected to balance the flexible utilization of time-frequency resources and the reduction of calculation complexity. At the same time, the configuration method of Solution 3 combines the carrier indication value and the scheduled cell indication signaling to determine the actually scheduled cells, effectively reducing the size of the indication field information and saving control overhead.

[0061] To implement the terminal-side channel monitoring method according to the embodiments of the present application, the embodiments of the present application further provide a channel monitoring device disposed in the terminal. As shown in FIG. 3, the device includes a first determination unit 301 configured to determine an index of a CCE occupied by a PDCCH candidate corresponding to a first DCI based on a first carrier indication value, wherein the first DCI represents a DCI capable of simultaneously scheduling uplink channels and / or downlink channels of at least two cells, the first carrier indication value represents a carrier indication value configured by the network side for a combination of first cells, and the combination of the first cells is a combination of cells scheduled by the first DCI.

[0062] Here, in one embodiment, any combination of cells schedulable by the first DCI is all composed of the first carrier indication values.

[0063] In one embodiment, the first carrier indication value is determined from a first parameter set, The first parameter set includes at least two different carrier indication values configured by the network side.

[0064] In one embodiment, each carrier indication value in the first parameter set respectively corresponds to a combination of cells schedulable by the first DCI.

[0065] In one embodiment, each carrier indication value in the first parameter set corresponds to a combination of at least two cells schedulable by the first DCI, and the number of cells in a combination of cells composed of the same carrier indication value is the same.
