Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a wireless communication data scheduling method and device. Background Art

[0002] The physical downlink control channel PDCCH carries downlink control information DCI. DCI contains the transmission resource scheduling information of the physical downlink shared channel PDSCH and the physical uplink shared channel PUSCH, as well as uplink power control indication, time slot format indication, etc. For example, for PDSCH scheduling, the network equipment dynamically sends DCI to the user equipment UE through PDCCH. The UE reads these control information to determine the time and frequency domain location of the data and how to demodulate / decode the PDSCH. DCI is divided into different formats according to the type of indication information. Referring to 3GPP TS 38.212.Vh.0.0, each DCI format corresponds to a size of DCI information and a parsing method. A given PDCCH can be composed of 1, 2, 4, 8, or 16 control channel elements CCE, and its specific value is determined by the DCI payload size and the required coding rate. The number of CCEs that make up the PDCCH is called the aggregation level AL.

[0003] The resource for transmitting DCI is called the control resource set CORESET. Since the AL of PDCCH and the mapping position of resources are not known in advance, the UE needs to blindly detect PDCCH. The PDCCH to be blindly detected is called a candidate PDCCH. The UE decodes all candidate PDCCHs in the search space of PDCCH. If the CRC check passes, the content of the decoded PDCCH is considered valid for the UE and the corresponding instructions are executed. The UE needs to decode all DCI formats that may be transmitted on the candidate PDCCH. Therefore, the more DCI formats there are, the greater the complexity of blind detection. In order to minimize the complexity of UE blind detection, it is necessary to limit the number of DCI payloads used to detect candidate PDCCHs per unit time.

[0004] Currently, scheduling one PDCCH can only be used to schedule PUSCH or PDSCH in one cell. In the case of relatively scattered wireless spectrum resources and narrow bandwidth, extending one PDCCH scheduling to support multi-cell PUSCH / PDSCH scheduling is beneficial to reduce control overhead, thereby ensuring that these scattered spectrum bands are used in a more spectrum / power efficient and flexible manner to meet the needs of high throughput and wide coverage.

[0005] If a PDCCH can schedule the PDSCH / PUSCH of K (K≥2) cells, the DCI contains the scheduling indication of the K cells. The length of the DCI format is related to the value of K, the configuration of the K cells related to the data scheduling information, the mode used for data transmission on the K cells, etc. Since the length of the DCI for data scheduling for each cell may be different, the complexity of the UE blind detection of the DCI format is increased. Summary of the invention

[0046] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0047] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0048] Figure 1 This is a flow chart of an embodiment of the method of this application.

[0049] The present application proposes a wireless communication data scheduling method, comprising the following steps:

[0050] Step 101: The configuration information includes the scheduling modes for K (K≥2) physical shared channels, where the scheduling modes are divided into L (L≥2) types. The length of the standard control information field corresponding to the j (j≤L) scheduling mode of the i (i≤K)th cell is Li j ;

[0051] The scheduling mode of the physical shared channel corresponds to the size and parsing method of the control information. In addition to being related to the scheduling mode, the size and parsing method of the control information are also related to the scheduling configuration related to the cell. For example, the BWP bandwidth of the current scheduling, whether the current scheduling supports cross-carrier scheduling, the HARQ-ACK feedback mode corresponding to the current scheduling, the time domain resource allocation configuration, etc. Corresponding to a scheduling mode of a cell, the standard control information field contains several information fields, indicating the scheduling information of the cell. For any information field of the standard control information field, its length is fixed, or its length is a determined value related to other configuration information of the cell. For example, the standard control information field contains a modulation and coding scheme information field with a fixed length of 5 bits; the standard control information field contains a frequency domain resource allocation information field with a length of bits. The number of RBs for which BWP is effective for this cell. The larger the value, the longer the frequency domain resource allocation information field of the standard control information field is. Different cells can use the same scheduling mode, and the lengths of the corresponding standard control information fields may be different. The lengths of the standard control information fields corresponding to different scheduling modes of the same cell may also be different.

[0052] For example, the size and parsing method of the control information for scheduling PDSCH using DCI format 1_0 can be regarded as one scheduling mode, and the size and parsing method of the control information for scheduling PDSCH using DCI format 1_1 can be regarded as another scheduling mode. The size and parsing method of the control information corresponding to each scheduling mode are preset.

[0053] The K (K≥2) physical shared channels are physical shared channels of K cells, or physical shared channels of C (C≤K) cells. If the K physical shared channels are physical shared channels of C cells, it is possible that the downlink control information schedules multiple physical shared channels of the same cell. The following embodiments are described by taking the K (K≥2) physical shared channels as the physical shared channels PDSCH of K cells as an example.

[0054] Assume that downlink control information is used for PDCCH scheduling of PDSCH of the first cell, the second cell, ..., the Kth cell. The present application presupposes that there are L scheduling modes of PDSCH. Each scheduling mode corresponds to a certain number of control information field lengths.

[0055] For example, the first scheduling mode corresponds to the standard control information field related to the DCI format 1_0: 1-bit DCI format indication field, bit frequency domain resource allocation field, 4-bit time domain resource allocation field, 4-bit time domain resource allocation field, 1-bit VRB to PRB mapping indication field, 5-bit modulation and coding scheme field, 1-bit new data indication field, etc.

[0056] For another example, the second scheduling mode corresponds to the standard control information fields related to the DCI format 1_1: 0 / 3-bit carrier index indication field, 0 / 1 / 2-bit BWP indication field, 0 / 1 / 2 / 3 / 4 / 5 / 6-bit time domain resource allocation field, etc. The length and content of some fields in DCI format 1_1 are determined according to the configuration information.

[0057] Furthermore, the configuration information is divided into a plurality of cell scheduling mode combinations, each of which includes respective scheduling modes of a plurality of cells. Examples of cell scheduling mode combinations are shown in Table 1.

[0058] The configuration information includes at least two combinations of the scheduling modes of the K cells. Taking K=3 as an example, examples of the scheduling mode combinations of the three cells include: combination mode 1: the first cell uses scheduling mode 1, the second cell uses scheduling mode 2, and the third cell uses scheduling mode 3; combination mode 2 is used for scheduling of three cells, wherein the first cell uses scheduling mode 3, the second cell uses scheduling mode 2, and the third cell uses scheduling mode 1; combination mode 3 is used for scheduling of two cells, wherein the first cell uses scheduling mode 3 and the second cell uses scheduling mode 3.

[0059] Step 102, the downlink control information includes a cell scheduling mode combination index and a cell scheduling mode combination control information; the cell scheduling mode combination index is used to indicate the cell scheduling mode combination mode; the cell scheduling mode combination control information includes the actual control information fields of M (M≤K) cells under the cell scheduling mode combination mode; the standard control information field of each cell corresponds to the actual control information field. When the length of the actual control information field is greater than or equal to the length of the standard control information field, the actual control information field includes the standard control information field; when the length of the actual control information field is less than the length of the standard control information field, the actual control information field includes a truncated portion of the standard control information field.

[0060] Preferably, the total length of the cell scheduling mode combination control information is preset. If a PDCCH can schedule PDSCH / PUSCH scheduling of K (K ≥ 2) cells, the DCI cell scheduling mode combination control information contains scheduling instructions for data transmission on K cells. Assume that the length of the DCI format cell scheduling mode combination control information is N K In order to control the blind detection complexity of UE, N K The fewer the value types, the better. However, limiting N K The value type will limit the scheduling flexibility of PUSCH / PDSCH.

[0061] The downlink control information of the present application is used to schedule data of M (M≤K) cells for the UE. First, the scheduling modes of each of the M cells are preset to be one of the L data scheduling modes. Then, the size and parsing method of the downlink control information are determined according to the data scheduling modes of each of the M cells. The combination of the data scheduling modes of each of the M cells is one of the scheduling modes of each of the K physical shared channels in the configuration information. The UE blindly detects the PDCCH carrying the scheduling information of the M cells according to the length of the downlink control information. For example, M=3, and the preset data scheduling mode combination of the three cells is that the first cell uses scheduling mode 3, the second cell uses scheduling mode 2, and the third cell uses scheduling mode 1. Then, after detecting the PDCCH with downlink control information, it can be determined that the X0~X1 bit information is the scheduling information of the first cell, corresponding to scheduling mode 3; the X2~X3 bit information is the scheduling information of the second cell, corresponding to scheduling mode 2; the X4~X5 bit information is the scheduling information of the third cell, corresponding to scheduling mode 1.

[0062] The "cell scheduling mode combination index" is used to indicate one of the preset cell scheduling mode combinations. Taking the "cell scheduling mode combination index" containing 3 bits as an example, the relationship between the preset index indication and the cell scheduling mode combination is shown in Table 1:

[0063] Table 1 Relationship between index indication and cell scheduling mode combination

[0064]

[0065]

[0066] It should be noted that the downlink control information is used to schedule data for M (M≤K) cells, and the configuration information includes the scheduling mode for each of the K physical shared channels. That is, it is not limited to any combination method for scheduling data for K cells. For example, when K=3 in the above example, combination method three is used for scheduling two cells. The combination method can also be used for scheduling one of the cells, without restriction here. That is to say, the PDCCH can at least use the first DCI format to schedule the PDCCH of K (K≥2) physical shared channels. The PDCCH can also use the first DCI format to schedule the PDCCH of any number of physical shared channels less than or equal to K. The downlink control information of the present application uses the first format of DCI, which contains the actual control information field of M (M≤K) cells.

[0067] Step 103: Use at least one cell scheduling mode combination as a reference scheduling mode combination, wherein the standard control information field length of each cell is used as the length of the actual control information field.

[0068] Taking K=3 as an example, the scheduling mode combinations of the three cells include: combination mode 1: the first cell uses scheduling mode 1, the second cell uses scheduling mode 2, and the third cell uses scheduling mode 3; combination mode 2 is used for scheduling of three cells, wherein the first cell uses scheduling mode 3, the second cell uses scheduling mode 2, and the third cell uses scheduling mode 1; combination mode 3 is used for scheduling of two cells, wherein the first cell uses scheduling mode 3 and the second cell uses scheduling mode 3. Then one of the combination modes is used as a reference scheduling mode combination, and the length of the actual downlink control information and the length of the cell scheduling mode combination control information composed of the actual downlink control information are determined according to the reference scheduling mode combination. The UE can detect the PDCCH according to the length of the cell scheduling mode combination control information and the length of each actual downlink control information. The reference scheduling mode combination can be preset or sent to the UE by the first configuration information.

[0069] The downlink control information contains a "cell scheduling mode combination index". After detecting the PDCCH, the correspondence between the information contained in other fields and the three cells is determined based on the "cell scheduling mode combination index" in the PDCCH. For example, the reference length of the downlink control information is R. After blindly detecting the PDCCH using this length, the current scheduling combination method can be determined based on the information carried by the first field. The first field is, for example, the "cell scheduling mode combination index" field, and its length is also preset. After determining the current combination method based on the first field, the correspondence between the information in other fields and the scheduling information of the three cells can be further determined. Figure 2 shown.

[0070] Figure 2This is a schematic diagram of the downlink control information format. If the first field indicates that the current PDCCH corresponds to combination mode one, then the N1 bit corresponds to the scheduling information of the first cell, the N2 bit corresponds to the scheduling information of the second cell, and the N3 bit corresponds to the scheduling information of the first cell. If the first field indicates that the current PDCCH corresponds to combination mode two, then the N′1 bit corresponds to the scheduling information of the first cell, the N′2 bit corresponds to the scheduling information of the second cell, and the N′3 bit corresponds to the scheduling information of the third cell. If the first field indicates that the current PDCCH corresponds to combination mode three, then the N″1 bit corresponds to the scheduling information of the first cell, and the N″2 bit corresponds to the scheduling information of the second cell.

[0071] Preferably, if the sum of the lengths of the standard control information fields of the M cells in the cell scheduling pattern combination of the downlink control information is greater than the sum of the lengths of the standard control information fields of the cells in the reference scheduling pattern combination, then the actual control information fields of w (1≤w≤M) cells in the downlink control information are the result of truncating their respective standard control information fields in a preset manner.

[0072] On the contrary, if the sum of the lengths of the standard control information fields of the M cells in the cell scheduling mode combination of the downlink control information is less than the sum of the lengths of the standard control information fields of the cells in the reference scheduling mode combination, the preset bits are filled in the downlink control information until the actual control information field is equal to the length of the standard control information field corresponding to the reference scheduling mode combination.

[0073] The downlink control information format of multiple cell PUSCH / PDSCH scheduling of the present application solution is adopted, and the UE detects the PDCCH in a preset manner, which meets the requirements of multi-cell scheduling and improves the capacity and efficiency of the control channel. On the other hand, it meets the flexibility requirements of data scheduling and has low blind detection complexity.

[0074] Figure 3 This is a flow chart of an embodiment of the method of the present application being applied to a network device.

[0075] The method described in any embodiment of the first aspect of the present application is used for a network device, comprising the following steps 201 and 204:

[0076] Step 201: Send the configuration information, where the configuration information is used to determine the scheduling mode of the downlink control information for each of the K cells;

[0077] Preferably, the method further comprises at least one of the following steps 202 to 203:

[0078] Step 202: Determine a reference scheduling mode combination, where the reference scheduling mode combination is preset or indicated by first configuration information.

[0079] Preferably, first configuration information is sent, wherein the first configuration information is used to indicate a reference scheduling mode combination

[0080] Step 203: Determine the manner in which the control information fields of the M cells are truncated according to a preset manner or second configuration information.

[0081] Preferably, second configuration information is sent, the second configuration information being used to indicate the manner in which the control information fields of the M cells are truncated. Further, the second configuration information includes at least one of a truncation priority order, a truncation information field, and a truncation length of the control information fields of the M cells.

[0082] Step 204: Send the downlink control information, where the downlink control information is used to schedule data of the M (M≤K) cells; the downlink control information includes a set length L A The cell scheduling mode combination index and setting length L B Combined control information of cell scheduling mode.

[0083] The set length L of the cell scheduling mode combination control information B It is the sum of the standard control information lengths of multiple cells in the reference scheduling pattern combination.

[0084] Figure 4 This is a flow chart of an embodiment of the method of the present application used in a terminal device.

[0085] The method described in any one of the embodiments of the first aspect of the present application is used in a terminal device, comprising the following steps 301, 304-305:

[0086] Step 301: Receive configuration information, where the configuration information is used to determine a scheduling mode of the downlink control information for each of the K cells;

[0087] Determine configuration information, where the configuration information is used to determine the scheduling mode of the downlink control information for each of the K physical shared channels, where the scheduling mode is divided into L (L ≥ 2) types, and the control information field length corresponding to the j (j ≤ L) scheduling mode of the i (i ≤ K) physical shared channel is L ij ;

[0088] Furthermore, the configuration information is divided into a plurality of cell scheduling mode combinations, each of which includes respective scheduling modes of a plurality of cells.

[0089] Preferably, at least one of the following steps 302 to 303 is included:

[0090] Step 302: Determine a reference scheduling mode combination, where the reference scheduling mode combination is preset or indicated by first configuration information.

[0091] Preferably, first configuration information is received, where the first configuration information is used to indicate a reference scheduling mode combination;

[0092] It should be noted that if the sum of the control information fields of the M cells in the cell scheduling mode combination of the downlink control information is greater than the sum of the control information field lengths of the cells in the reference scheduling mode combination, then the actual control information fields of w (1≤w≤M) cells in the PDCCH are truncated in a preset manner. Still taking M=3 as an example, assuming that the reference scheduling mode combination is combination mode 1: the first cell uses scheduling mode 1, the second cell uses scheduling mode 2, and the third cell uses scheduling mode 3, the corresponding scheduling control information field length of each cell is L 11 +L 22 +L 33 When the PDCCH using downlink control information is used for scheduling in combination mode 2, the corresponding control information field length is L 13 +L 22 +L 31 If L 13 +L 22 +L 31 >L 11 +L 22 +L 33 , then at least one of the control information field lengths for each of the three cells in the PDCCH is truncated. For example, the actual control information field length for the first cell in the PDCCH is L' 13 , L′ 13 <L 13 ; and or, the actual control information field length for the second cell in the PDCCH is L' 22 , L′ 22 <L 22 ; The actual control information field length for the third cell in PDCCH is L' 31 , L′ 31 <L 31 .

[0093] Step 303: Determine the manner in which the control information fields of the M cells are truncated according to a preset manner or second configuration information.

[0094] Preferably, second configuration information is received, wherein the second configuration information is used to indicate the manner in which the control information fields of the M cells are truncated; further, the second configuration information includes at least one of a truncation priority order, a truncation information field, and a truncation length of the control information fields of the M cells.

[0095] Optionally, the second configuration information includes at least one of a truncation priority order, a truncation information field, and a truncation length of the M cell control information fields. The truncation priority order refers to which cell's information field is truncated first and which cell's information field is truncated later. The truncation information field refers to which parts of the information in the control information field are truncated. The truncation length refers to how many bits of information are truncated. For example, when L is determined according to a preset or second configuration information, 13 +L 22 +L 31 >L 11 +L 22 +L 33 When the first reference field in the control information field of the first cell is first truncated by n1 bits, and at most by n′1 bits, so that L 13 +L 22 +L 31 -n1=L 11 +L 22 +L 33 If L 13 +L 22 +L 31 -n′1>L 11 +L 22 +L 33 , then the second reference field in the control information field of the second cell is shortened by n2 bits, and at most by n′2 bits, so that L 13 +L 22 +L 31 -n′1-n2=L 11 +L 22 +L 33 If L 13 +L 22 +L 31 -n′1-n′2>L 11 +L 22 +L 33 , then the third reference field in the control information field of the third cell is shortened by n3 bits to satisfy L 13 +L 22 +L 31 -n′1-n′2-n3=L 11 +L 22 +L 33 Alternatively, the order of truncation is to first truncate the first information field in the control information field of the first cell by 1 bit, and then determine whether L 13 +L 22 +L 31 -1=L 11 +L 22 +L 33 If L 13 +L22 +L 31 -1>L 11 +L 22 +L 33 , then shorten the second information field in the control information field of the second cell by 1 bit to determine whether L 13 +L 22 +L 31 -1-1=L 11 +L 22 +L 33 If L 13 +L 22 +L 31 -1-1>L 11 +L 22 +L 33 , then shorten the third information field in the control information field of the third cell by 1 bit to determine whether L 13 +L 22 +L 31 -1-1-1=L 11 +L 22 +L 33 If L 13 +L 22 +L 31 -1-1-1>L 11 +L 22 +L 33 , then the first information field in the control information field of the first cell is truncated by 1 bit, and this cycle is repeated until the actual control information field length after truncation is equal to the standard control information field length corresponding to the reference scheduling mode combination.

[0096] It should be noted that the second configuration information includes at least one of the truncated priority order, truncated information domain, and truncated length of the M cell control information fields. The M cells are part or all of the K cells. The second configuration information may include at least one of the truncated priority order, truncated information domain, and truncated length of the K cell control information fields. Furthermore, the terminal device may be configured with more than K cells, but only supports one PDCCH to schedule the physical shared channels of K cells. The physical shared channels of other cells are scheduled by scheduling one PDCCH to schedule one PDSCH / PUSCH.

[0097] Step 304: Receive the downlink control information, where the downlink control information is used to schedule data of the M (M≤K) cells.

[0098] According to the set length L A The cell scheduling mode combination index and setting length L BBlindly detect downlink control information in the PDCCH using the cell scheduling mode combined control information, where the downlink control information is used to schedule M (M≤K) physical shared channels;

[0099] Preferably, the downlink control information includes a common control information field for scheduling the M physical shared channels and a control information field for each of the M physical shared channels.

[0100] It should be noted that the downlink control information is used to schedule data of M (M≤K) cells. The downlink control information may include a common control information field for scheduling the M cells and a control information field for each of the M cells. The method of determining the scheduling mode of each of the M cells and the corresponding control information field of the downlink control information according to the configuration information described in the present application is applicable to determining the control information field for each of the M cells in the downlink control information.

[0101] Step 305: Determine, according to the configuration information, the cell scheduling mode combination index and the length of the cell scheduling mode combination control information, identify the scheduling information of each of the M physical shared channels in the downlink control information, and optionally, the physical shared channel is any one of PDSCH and PUSCH. The M physical shared channels may all be PDSCH, or all be PUSCH, or some may be PDSCH and some may be PUSCH.

[0102] The configuration information includes at least one combination of the scheduling modes of the K cells. Taking K=3 as an example, the downlink control information corresponds to the first cell using scheduling mode 3, the second cell using scheduling mode 2, and the third cell using scheduling mode 1. The scheduling information for the first cell in the downlink control information is L 13 bit, the scheduling information for the second cell is L 13 bit, the scheduling information for the third cell is L 31bits. According to the preset length of the cell scheduling mode combination control information corresponding to the combination, the data scheduling information of each cell carried in the PDCCH can be detected and determined. In this way, the UE does not need to blindly detect the downlink control information formats corresponding to all scheduling mode combinations of the three cells respectively, which can reduce the blind detection complexity of the UE. On the other hand, the preset combination of scheduling modes of the K cells can meet the data scheduling needs of each cell within a period of time. Corresponding to step 301, the UE pre-acquires the first search space type configuration information, and detects the PDCCH according to the downlink control information of the set length in the search space corresponding to the first search space configuration information. There are multiple combinations of scheduling modes for the K cells. Optionally, the configuration information only contains one method. When the configuration information indicates that the scheduling mode of the downlink control information for each of the K cells is combination mode one, the size and resolution of the downlink control information are of the first mode, and the PDCCH is detected in the search space corresponding to the first search space configuration information according to the first mode; when the configuration information indicates that the scheduling mode of the downlink control information for each of the K cells is combination mode two, the size and resolution of the downlink control information are of the second mode, and the PDCCH is detected in the search space corresponding to the first search space configuration information according to the second mode.

[0103] When the configuration information indicates that the downlink control information has multiple combinations of scheduling modes for each of the K cells, one of the combinations is used as a reference scheduling mode combination, and the length of the actual downlink control information and the length of the cell scheduling mode combination control information composed of the actual downlink control information are determined according to the reference scheduling mode combination. The UE can detect the PDCCH according to the length of the cell scheduling mode combination control information and the length of each of the actual downlink control information. The reference scheduling mode combination can be preset or sent to the UE by the first configuration information.
