[0015] In order to make the technical problems to be solved, the technical means and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with drawings and specific embodiments.

[0016] The method of the present invention is performed by user equipment (UE), which may refer to an access terminal, subscriber unit, subscriber station, mobile station, mobile base, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user equipment. The terminal device may be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, or a wearable device.

[0017] For ease of explanation, it should be understood that in the embodiments of the present invention, multiple carriers or BWPs means multiple carriers or multiple BWPs, each carrier or BWP means each carrier or each BWP, multiple carrier groups or BWP groups means multiple carrier groups or multiple BWP groups, and a single carrier or BWP means a single carrier or a single BWP.

[0018] As shown in FIG. 1, the resource determination method of the embodiment of the present invention is performed by a user side device, and includes the following steps:

[0019] In step 101, time domain resource indication information of downlink control information DCI is obtained, where the time domain resource indication information supports scheduling of multiple carriers or partial bandwidth BWP.

[0020] In this step, the time domain resource indication information of the DCI supports scheduling of multiple carriers or BWPs, and can also schedule a single carrier or BWP, so this step obtains the time domain resource indication information of the DCI and understands the scheduling of the network side device before executing the next step.

[0021] In step 102, determining scheduling time domain resources on multiple carriers or BWPs based on the time domain resource indication information.

[0022] In this step, after obtaining time domain resource indication information supporting scheduling of multiple carriers or BWPs in step 101, determine the scheduling time domain resources on multiple carriers or BWPs corresponding to the time domain resource indication information based on the time domain resource indication information.

[0023] Therefore, according to steps 101 and 102, the user side equipment executing the embodiment method of the present invention obtains the time domain resource indication information of the DCI, and then can determine the scheduling time domain resources on multiple carriers or BWPs, since the time domain resource indication information supports scheduling of multiple carriers or BWPs, thereby realizing scheduling of multiple carriers or BWPs using one DCI and effectively reducing the PDCCH overhead in scheduling.

[0024] For example, when applied to a DSS scenario, a network side device generates and sends a DCI including time domain resource indication information, and the time domain resource indication information supports scheduling of multiple carriers or BWPs. Therefore, upon receiving the DCI, a user side device can obtain the time domain resource indication information and determine the scheduling time domain resources on multiple carriers or BWPs.

[0025] It should be noted that the information included in the DCI is realized by the corresponding field. Therefore, optionally, in this embodiment, step 101 can be: determining a corresponding first indication field in the DCI of the time domain resource indication information according to configuration information of candidate resources scheduled by the DCI; and obtaining the time domain resource indication information based on the first indication field.

[0026] Here, the configuration information of the candidate resources scheduled by the DCI can be obtained by a method such as configuration (e.g., higher-level signaling configuration) or pre-definition, and thus the user side equipment first determines the corresponding first indication field in the DCI of the time domain resource indication information based on the configuration information, and then further obtains the time domain resource indication information through the first indication field.

[0027] Optionally, in the first indication field, the subfields corresponding to each carrier or BWP are arranged according to the order of the first identifier; or The subfield corresponding to each carrier or BWP is assigned a higher or lower order time domain resource indication.

[0028] The first identifier may be a cell identifier (ID), a carrier indicator field (CIF), or a BWP ID. When ordering according to the order of the first identifiers, the first identifiers may be ordered in ascending or descending order. In this case, the sizes of the subfields corresponding to each carrier or BWP in the first indication field may be the same or different. Furthermore, the subfields corresponding to each carrier or BWP in the first indication field may be assigned a predetermined position, preferably a higher or lower position, for indicating the time domain resource of the cell. For example, if the DCI schedules cell1, and the subfield corresponding to cell1 in the first indication field is assigned a higher position for indicating the time domain resource of the cell1, assuming that the subfield corresponding to cell1 in the first indication field is 5 bits long and only 2 bits are required for indicating the time domain resource of the cell1, the upper 2 bits of the 5-bit subfield corresponding to cell1 in the first indication field are used to indicate the time domain resource of the cell1.

[0029] Optionally, in this embodiment, the step of determining a corresponding first indication field in the DCI of the time domain resource indication information based on configuration information of candidate resources scheduled by the DCI comprises: According to the configuration information of each carrier or BWP in the candidate resource, obtain the size of a second indication field corresponding to each carrier or BWP; determining the size of the first instruction field based on the size of the second instruction field.

[0030] Optionally, the step of determining the size of the first instruction field based on the second instruction field comprises: the sum of the sizes of all the second indication fields is the size of the first indication field; or The method includes a step of setting the size of the first instruction field to the size of the largest second instruction field among all the second instruction fields.

[0031] In this way, after obtaining the size of the second indication field corresponding to each carrier or BWP based on the configuration information of each carrier or BWP in the candidate resources, the size of the first indication field may be the sum of the sizes of all the second indication fields, that is, the time domain resource allocation related fields used by the DCI to schedule each carrier or BWP are independent, and in this case, preferably the subfields corresponding to each carrier or BWP in the first indication field are arranged according to the order of the first identifier. Taking cell ID as an example, if Cell1 and Cell2 can be scheduled by DCI, it is determined that the size of the second indication field, which is a time domain resource allocation related field corresponding to Cell1, is S1 based on the configurations on Cell1 and Cell2, and the size of the second indication field corresponding to Cell2 is S2. Therefore, the size of the first indication field in the DCI is S1+S2, and in the first indication field, the first S1 bits are the subfield (time domain allocation related field) corresponding to Cell1, and the last S2 bits are the subfield corresponding to Cell2.

[0032] Alternatively, the size of the largest second indication field among all second indication fields may be taken as the size of the first indication field, that is, the time domain resource allocation related field used by DCI to schedule each carrier or BWP is shared by each carrier or BWP, in this case, preferably, the subfields corresponding to each carrier or BWP in the first indication field are assigned upper or lower to their respective time domain resource indications. Taking cell ID as an example, if Cell1 and Cell2 can be scheduled by DCI, the size of the second indication field corresponding to Cell1 is S1 according to the configuration on Cell1 and Cell2, and the size of the second indication field corresponding to Cell2 is S2, so the size of the first indication field in the DCI is max(S1,S2), and in the first indication field, the subfield corresponding to Cell1 is assigned upper (or lower) S1 bit to its time domain resource indication, and the subfield corresponding to Cell2 is assigned upper (or lower) S2 bit to its time domain resource indication. Therefore, if S1>S2, and the subfield corresponding to Cell1 is assigned the most significant S1 bit for its time domain resource indication, and the subfield corresponding to Cell2 is assigned the least significant S2 bit for its time domain resource indication, then when the DCI schedules Cell1, the size of the first indication field of the DCI is S1 bit, and the most significant S1 bit of the first indication field is the time domain resource indication of Cell1, and when the DCI schedules Cell2, the size of the first indication field of the DCI is S1 bit, and the least significant S2 bit of the S1 bit is the time domain resource indication of Cell2. Of course, the subfields corresponding to each carrier or BWP in the first indication field may be assigned all significant or all significant for their respective time domain resource indications.

[0033] Also, considering that the candidate resources include a plurality of carrier groups or BWP groups, the step of determining, for a plurality of carrier groups or BWP groups, a corresponding first indication field in the DCI of the time domain resource indication information based on configuration information of candidate resources to be scheduled by the DCI, selectively, When the candidate resources include multiple carrier groups or BWP groups, obtaining a size of a third indication field corresponding to each carrier group or BWP group according to configuration information of the multiple carrier groups or BWP groups; and determining the size of the first instruction field based on the size of the third instruction field.

[0034] Optionally, the step of determining the size of the first instruction field based on the size of the third instruction field comprises: A step of setting the size of the first instruction field to the size of the largest third instruction field among all the third instruction fields; or obtaining a size L of the first indication field according to the formula L=SMAX*N, where SMAX is the size of the largest single carrier or BWP indication field in the plurality of carrier or BWP groups, and N is the number of largest carriers or BWPs in the plurality of carrier or BWP groups in the candidate resource; or The step of setting the size of the first indication field to the size of the largest single carrier or BWP indication field in the plurality of carrier groups or BWP groups.

[0035] In this way, the size of the third indication field corresponding to each carrier group or BWP group may be obtained based on the configuration information of multiple carrier groups or BWP groups, and the size of the largest third indication field among all the third indication fields may be set as the size of the first indication field. If multiple carrier groups or BWP groups can be scheduled using DCI of the same size, the subfields corresponding to each carrier or BWP in the first indication field may be arranged in the order of the first identifier. If the first indication field has excess bits after arrangement, the excess bits may be set to all zeros as invalid bits. Alternatively, the subfields corresponding to each carrier or BWP in the first indication field may be assigned upper or lower positions in the time domain resource indication.

[0036] For example, carrier group 1 (including Cell1 and Cell2) and carrier group 2 (including Cell3 and Cell4) can be scheduled by DCI, and the configuration information of each of the two carrier groups indicates that the size of the third indication field corresponding to carrier group 1 is 5 bits (2 bits for Cell1 and 3 bits for Cell2) and the size of the third indication field corresponding to carrier group 2 is 10 bits (4 bits for Cell3 and 6 bits for Cell4), so the size of the first indication field is 10 bits. Therefore, when the subfields corresponding to each carrier or BWP in the first indication field are arranged according to the order of the first identifier, for carrier group 1, the first 2 bits of the first indication field are the subfield corresponding to Cell1 and the last 3 bits are the subfield corresponding to Cell2, and for carrier group 2, the first 4 bits of the first indication field are the subfield corresponding to Cell3 and the last 6 bits are the subfield corresponding to Cell4. Thus, when DCI schedules Cell1 and Cell2, of the 10 bits of the first indication field of DCI, the first 2 bits are the subfield corresponding to Cell1 (used for scheduling Cell1), the next 3 bits are the subfield corresponding to Cell2, and the last 5 bits may be set to all zeros.

[0037] Alternatively, the size of the largest single carrier or BWP indication field in multiple carrier groups or BWP groups may be set as the size of the first indication field. The sizes of the time domain resource allocation related fields (i.e., single carrier or BWP indication fields) required for each carrier or BWP in multiple carrier groups or BWP groups that can be scheduled by DCI are S1, S2, ..., S K where K is the total number of all carriers or BWPs in the carrier group or BWP group that can be scheduled by the DCI. Thus, the size of the first indication field is S max and S max =max(S1, S2, …, SK ). When multiple carrier groups or BWP groups can be scheduled by DCI of the same size, it is preferable that the subfields corresponding to each carrier or BWP in the first indication field are assigned with higher or lower time domain resource indication. For example, if carrier group 1 (including Cell1 and Cell2) and carrier group 2 (including Cell3 and Cell4) can be scheduled by DCI, and the configuration information of each carrier or BWP shows that Cell1 is 2 bits, Cell2 is 3 bits, Cell3 is 4 bits, and Cell4 is 6 bits, the size of the first indication field is 6 bits. If the subfields corresponding to each carrier or BWP in the first indication field are all assigned with higher time domain resource indication, when DCI schedules Cell1 and Cell2, of the 6 bits in the first indication field of DCI, the first 2 bits are subfields corresponding to Cell1, the next 3 bits are subfields corresponding to Cell2, and the last bit is an invalid bit that may be set to zero.

[0038] Or, the formula L=S MAX *N, where N is the maximum number of carriers or BWPs in the multiple carrier groups or BWP groups in the candidate resource. If multiple carrier groups or BWP groups can be scheduled by DCI of the same size, the subfields corresponding to each carrier or BWP in the first indication field are arranged according to the order of the first identifier, where the size of the subfields corresponding to each carrier or BWP is S MAX Each S MAX Higher S of bit i bit or lower S ibitcorresponds to the i-th carrier or BWP, and the size of the subfield corresponding to each carrier or BWP in the first indication field may be different, and the size of the subfield corresponding to each carrier or BWP is equal to the size of its time domain resource indication.

[0039] For example, carrier group 1 (including Cell1 and Cell2) and carrier group 2 (including Cell3 and Cell4) can be scheduled by DCI, and the configuration information of each carrier or BWP shows that Cell1 is 2 bits, Cell2 is 3 bits, Cell3 is 4 bits, and Cell4 is 6 bits. Then, the size of the first indication field is 10*2 bits=20 bits. When the subfields corresponding to each carrier or BWP in the first indication field are arranged according to the order of the first identifier, when the DCI schedules Cell1 and Cell2, of the 20 bits of the first indication field of the DCI, the first 10 bits are the subfields corresponding to Cell1, and the last 10 bits are the subfields corresponding to Cell2, and of the first 10 bits, only the upper 2 bits or the lower 2 bits are used to indicate the time domain resource of Cell1, and of the last 10 bits, only the upper 3 bits or the lower 3 bits are used to indicate the time domain resource of Cell2. On the other hand, of the 20 bits of the first indication field of the DCI, consecutive bits may be used to indicate the time domain resource of a cell, and the time domain resource of a cell may be indicated directly in the subfield corresponding to each cell. In this case, of the 20 bits, the first 2 bits are the subfields corresponding to Cell1, and these 2 bits directly indicate the time domain resource of Cell1, and the last 3 bits are the subfields corresponding to Cell2, and these 3 bits indicate the time domain resource of Cell2. Thus, the last 15 bits are invalid bits and may be set to all zeros.

[0040] Optionally, in this embodiment, the step of determining a corresponding first indication field in the DCI of the time domain resource indication information based on configuration information of candidate resources scheduled by the DCI comprises: The method includes obtaining the size of the first indication field based on configuration information of a reference carrier or BWP in the candidate resource.

[0041] Here, the reference carrier or BWP is set by a method such as configuration or pre-definition, and the size of the first indication field is obtained according to the configuration information of the reference carrier or BWP. The reference carrier or BWP may be a primary cell (Pcell), a cell or BWP with the smallest or largest cell ID, or a cell or BWP with the smallest or largest subcarrier spacing (SCS).

[0042] Optionally, in this embodiment, the step of determining a corresponding first indication field in the DCI of the time domain resource indication information based on configuration information of candidate resources scheduled by the DCI comprises: The method includes selecting a size of the first indication field according to a preset policy based on whether the DCI is single-carrier or BWP scheduling.

[0043] The preset policy is: If the DCI is a single carrier or BWP scheduling, obtain the size of the first indication field according to configuration information of the scheduled carrier or BWP; If the DCI is not a single-carrier or BWP scheduling, obtain a size of a fourth indication field corresponding to each carrier group or BWP group according to configuration information of a plurality of carrier groups or BWP groups in the candidate resource, and set the size of the first indication field to the size of the largest fourth indication field among all the fourth indication fields, or set the size of the largest single-carrier or single BWP indication field in the plurality of carrier groups or BWP groups to the size of the first indication field, or use the formula L'=S' MAX *N to obtain the size L' of the first instruction field, where S' MAX is the size of the largest single carrier or BWP indication field in the plurality of carrier groups or BWP groups, and N is the number of largest carriers or BWPs in the plurality of carrier groups or BWP groups in the candidate resource, or obtaining the size of the first indication field based on configuration information of a reference carrier or BWP in the candidate resource.

[0044] Thus, when the DCI is a single carrier or BWP scheduling, the size of the first indication field is obtained according to the configuration information of the scheduled carrier or BWP, for example, the size of the first indication field is the size S of the scheduled carrier or BWP indication field obtained according to the configuration information. single If the DCI is not a single carrier or BWP scheduling, obtain the size of the fourth indication field corresponding to each carrier group or BWP group according to the configuration information of multiple carrier groups or BWP groups in the candidate resource, and then use the largest size of the fourth indication field among all the fourth indication fields as the size of the first indication field, or use the largest size of a single carrier or BWP indication field among multiple carrier groups or BWP groups as the size of the first indication field, or use the formula L'=S' MAX*N, or the size of the first indication field may be obtained based on the configuration information of the reference carrier or BWP in the candidate resource.

[0045] Here, when the DCI is not a single carrier or BWP scheduling, the implementation of determining the first indication field is similar to the implementation of determining the size of the first indication field based on the size of the third indication field described above, and the detailed description is omitted here. The reference carrier or BWP is as described above.

[0046] Optionally, in this embodiment, step 102 includes: When the DCI schedules a reference carrier or a BWP, the scheduling time domain resource is the time domain resource indicated by the time domain resource indication information; If the DCI schedules something other than a reference carrier or a BWP, determining the scheduling time domain resource based on a time domain location for scheduling the reference carrier or the BWP.

[0047] Here, the reference carrier or BWP is set by a method such as configuration or pre-definition, and the size of the first indication field is obtained according to the configuration information of the reference carrier or BWP. The reference carrier or BWP may be a primary cell (Pcell), a cell or BWP with the smallest or largest cell ID, or a cell or BWP with the smallest or largest subcarrier spacing (SCS). If the DCI schedules the reference carrier or BWP, the scheduling time domain resource is the time domain resource indicated by the time domain resource indication information. If the DCI schedules a carrier other than the reference carrier or BWP, the scheduling time domain resource is further determined based on the time domain position at which the reference carrier or BWP is scheduled, such as the first slot, the last slot, or all slots overlapping with the time domain position at which the reference carrier or BWP is scheduled. The scheduled time position of the physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) is the symbol position of the corresponding intra-slot symbol indication (Start and length indicator value, SLIV) on the determined slot or slots. In this way, overhead is saved and the length and location of the time domain resources allocated to each cell are consistent.

[0048] Optionally, in this embodiment, the time domain resource indication information is: The second identifier is an indicator identifier of a time domain resource.

[0049] In this way, when the time domain resource indication information of DCI is shared among each carrier or BWP, indication identifiers of multiple time domain resources may be configured, and time domain resource indication may be realized by specific indication identifiers and / or offset values.

[0050] For example, a combination of second identifiers of time domain resource indication information of multiple cells may be configured. In the case where the multiple cells are Cell1 and Cell2, if eight time domain resource allocation values are configured for Cell1 and Cell2, the combination of the second identifier and the indication index identifier Cell1 for the time domain resource allocation value of Cell1 may be configured. The correspondence between the Time Domain Resource Allocation (TDRA) index and the indication index identifier Cell2 TDRA index for the time domain resource allocation value of Cell2 is shown in Table 1 below.

[0051] [Table 1]

[0052] As another configuration method, a new TDRA table (distinguished from the TDRA table when scheduled individually) may be configured for each carrier or BWP included in the carrier group or BWP group, and these may be combined to form a new integrated TDRA table.

[0053] Alternatively, the portion of the integrated TDRA table indicating a particular time domain resource allocation may be shared by multiple carriers or BWPs, for example, the integrated TDRA table may configure K0 / K2 of Cell1, K0 / K2 of Cell2 and a shared SLIV.

[0054] Optionally, in this embodiment, the time domain resource indication information includes first indication information and second indication information; The first instruction information is an instruction shared by each carrier or BWP, and the second instruction information is an instruction independent for each carrier or BWP.

[0055] Alternatively, the first indication is a slot indication and the second indication is a symbol-in-slot indication; or The first indication information is an intra-slot symbol indication, and the second indication information is a slot indication.

[0056] In this way, it is possible to increase the flexibility of indicating some time domain resource indication information, which is useful in time division duplex (TDD) scenarios in cells with different uplink (UL) and downlink (DL) configurations.

[0057] For two cells Cell1 and Cell2, if the slot indication (K0 / K2) is indicated independently for each carrier or BWP, and the intra-slot symbol indication SLIV is indicated commonly for each carrier or BWP, then in the field where the time domain resource indication information exists, the first S1 bit indicates the K0 / K2 value of Cell1, the subsequent S2 bit indicates the K0 / K2 value of Cell2, and the final S3 bit indicates the SLIV values of Cell1 and Cell2.

[0058] Also, optionally, in this embodiment, after step 102: The method further includes determining that the scheduling time domain resource is invalid if the scheduling time domain resource conflicts with the uplink-downlink configuration of a corresponding carrier or BWP.

[0059] Thus, if the TDD uplink and downlink configurations configured for the carrier group or BWP group scheduled by the DCI are different, or if the time domain resources scheduled by the DCI are different from the uplink and downlink configurations on one or more carriers, the scheduled resources are invalid. For example, if the DCI schedules an uplink transmission and some symbols of the resources represented by the TDRA indicated on carrier 2 are configured as downlink symbols, the UE considers the scheduling invalid and does not transmit any data. In this case, the resources represented by the TDRA indicated on carrier 1 are not conflicting, the uplink PUSCH scheduling is valid, and the UE transmits data.

[0060] From the above, after obtaining the time domain resource indication information of DCI, the scheduling time domain resources on multiple carriers or BWPs can be determined, since the time domain resource indication information supports scheduling of multiple carriers or BWPs, thereby realizing scheduling of multiple carriers or BWPs using one DCI and effectively reducing the PDCCH overhead in scheduling.

[0061] As shown in FIG. 2 , an embodiment of the present invention further provides a resource indication method, the resource indication method being performed by a network side device: generating downlink control information (DCI) including time domain resource indication information (TDI), where the time domain resource indication information supports scheduling of multiple carriers or fractional bandwidths (BWP); Step 202 of sending the DCI to the user side equipment.

[0062] According to steps 201 and 202, the network side device applying the embodiment method of the present invention generates a DCI including time domain resource indication information, and the time domain resource indication information supports scheduling of multiple carriers or BWPs. Therefore, by sending the DCI to the user side device, the user side device can determine the scheduling time domain resources on multiple carriers or BWPs, thereby realizing scheduling of multiple carriers or BWPs using one DCI and effectively reducing the PDCCH overhead in scheduling.

[0063] Optionally, step 201 includes: determining a corresponding first indication field in the DCI of the time domain resource indication information according to configuration information of candidate resources scheduled by the DCI; and obtaining DCI including the time domain resource indication information based on the first indication field.

[0064] Optionally, the step of determining a corresponding first indication field in the DCI of the time domain resource indication information based on configuration information of candidate resources scheduled by the DCI comprises: According to the configuration information of each carrier or BWP in the candidate resource, obtain the size of a second indication field corresponding to each carrier or BWP; determining the size of the first instruction field based on the size of the second instruction field.

[0065] Optionally, the step of determining the size of the first instruction field based on the second instruction field comprises: the sum of the sizes of all the second indication fields is the size of the first indication field; or The method includes a step of setting the size of the largest second instruction field among all the second instruction fields as the size of the first instruction field.

[0066] Optionally, the step of determining a corresponding first indication field in the DCI of the time domain resource indication information based on configuration information of candidate resources scheduled by the DCI comprises: When the candidate resources include multiple carrier groups or BWP groups, obtaining a size of a third indication field corresponding to each carrier group or BWP group according to configuration information of the multiple carrier groups or BWP groups; and determining the size of the first instruction field based on the size of the third instruction field.
