Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication processing, and in particular to a resource indication method, user equipment, network equipment and computer storage medium. BACKGROUND

[0002] In the existing LTE system, the frequency domain resource allocation granularity is RBG (Resource Block Group), and the number of resource blocks (RB) contained in one RBG, i.e. RBG size, is related to the system bandwidth, as shown in Table 1:

[0003] System bandwidth range RBG size ≦10 1 11-26 2 27-63 3 64-110 4

[0004] Table 1

[0005] In the 5G NR standard, it has been determined that the RBG size will be related to the size of the bandwidth part (BWP) of the terminal, rather than the size of the system bandwidth.

[0006] However, in the prior art, the mapping relationship between the RBG size and the bandwidth part size is not clear. If different BWP sizes correspond to different RBG sizes, better scheduling flexibility can be obtained, but since different terminals can have different BWP sizes, multiple scheduling granularities need to be used simultaneously in one cell, which will cause high base station scheduling complexity. If the same RBG size is used for different RBG sizes, the base station scheduler can be simplified, but the scheduling flexibility will be greatly limited. SUMMARY

[0007] To solve the above technical problems, the embodiments of the present application provide a resource indication method, user equipment, network equipment and computer storage medium.

[0011] allocating a frequency domain resource according to the size of the target resource block group and the first control information sent by the network side;

[0012] The at least two candidate mapping relationships include at least a first mapping relationship and a second mapping relationship. In the first mapping relationship, each group of bandwidth part size ranges maps different resource block group sizes.

[0032] In order to enable more detailed understanding of the features and technical contents of the embodiments of the application, the implementation of the embodiments of the application will be described in detail below with reference to the accompanying drawings, and the accompanying drawings are only used for reference description and do not limit the embodiments of the application.

[0033] Embodiment one,

[0034] The embodiment of the application provides a resource indication method, which is applied to user equipment, such as a user equipment. Figure 1 As shown in the figure, the method comprises the following steps:

[0035] Step 101: selecting a target mapping relationship from at least two candidate mapping relationships;

[0036] Step 102: determining the size of the target resource block group according to the bandwidth part size range in the target mapping relationship;

[0037] Step 103: allocating frequency domain resources according to the size of the target resource block group and the first control information sent by the network side;

[0038] The at least two candidate mapping relationships include at least a first mapping relationship and a second mapping relationship; in the first mapping relationship, each bandwidth part size range maps to a different resource block group size; in the second mapping relationship, at least two bandwidth part size ranges can map to the same resource block group size.

[0039] For the two mapping relationships, refer to Table 2:

[0040]

[0041]

[0042] Table 2

[0043] As can be seen from Table 2, in the first mapping relationship, different bandwidth part size ranges correspond to different resource block group sizes, for example, in Table 2, the mapped resource block group sizes are 1, 2, 4, 8, and 16; and in the second mapping relationship, multiple different bandwidth part sizes correspond to the same resource block group size, for example, in Table 2, three bandwidth part size ranges correspond to the same resource block group size, which is 4, and the remaining two bandwidth part size ranges correspond to another resource block group size, which is 16. In addition, the size range of BWP in the table can be set according to actual conditions, and the table is only an example, and not exhaustive.

[0044] Here, the target mapping relationship can be the first mapping relationship or the second mapping relationship.

[0045] It should also be understood that there can be more mapping relationships in practice, but not exhaustive in this embodiment.

[0046] In the foregoing step 101, the at least two candidate mapping relationships can be at least two candidate mapping relationships preset in the user equipment; or the at least two candidate mapping relationships can be obtained from the network side.

[0047] The at least two candidate mapping relationships obtained from the network side can be obtained from radio resource control (RRC) configuration information, or can be obtained from other information.

[0048] Specifically, selecting the target mapping relationship from the at least two candidate mapping relationships includes:

[0049] selecting a target mapping relationship from the at least two candidate mapping relationships according to a first configuration signaling sent by the network side;

[0050] Alternatively,

[0051] selecting a target mapping relationship from the at least two candidate mapping relationships according to a preset rule.

[0052] The first configuration signaling can be obtained through RRC configuration information. In the first configuration signaling, the capability information of the network side can be included, so that the user equipment determines which target mapping relationship is selected from the at least two candidate mapping relationships according to the first configuration signaling. For example, when the capability of the network side (base station) represents that the load capability is low, the second mapping relationship can be selected as the target mapping relationship, and vice versa, the first mapping relationship can be selected as the target mapping relationship.

[0053] In addition, the target mapping relationship that the user equipment needs to select can be obtained in the first configuration signaling. In this way, the network side (that is, the base station) can judge whether its own capability can bear a larger load, and if so, the user equipment can be notified through the first configuration signaling to select the first mapping relationship as the target mapping relationship; otherwise, the user equipment can be notified through the first configuration signaling to select the second mapping relationship as the target mapping relationship.

[0054] In the selecting a target mapping relationship from the at least two candidate mapping relationships according to a preset rule, the preset rule can be determined according to the system load detected by the user equipment, for example, when the current system load is detected to be large, the second mapping relationship can be selected as the target mapping relationship, and vice versa, the first mapping relationship can be selected as the target mapping relationship. The system load can be detected through the system load information sent by the network side, and the specific sending method is not described in the embodiment.

[0055] In addition, the quality of the reference signal of the network side detected by the user equipment can also be used for judgment, for example, when the quality of the reference signal of the network side is detected to be poor, the second mapping relationship can be selected as the target mapping relationship, and vice versa, the first mapping relationship can be selected as the target mapping relationship.

[0056] The judgment method of the quality of the reference signal can be that the interference is less than a preset interference threshold value, which represents that the quality is good, and vice versa. Alternatively, the signal-to-noise ratio can be higher than a preset signal-to-noise ratio threshold value, which represents that the quality is good, and vice versa. It should be understood that there can be other judgment methods, which are not exhaustively described in the embodiment.

[0057] In the foregoing step 102, the size of the target resource block group is determined according to the bandwidth part size range in the target mapping relationship; when the target mapping relationship is determined, the sizes of the multiple resource block groups corresponding to the multiple bandwidth part size ranges of the user equipment can be known, which can refer to the foregoing Table 2.

[0058] Further, in the step 103, the size of the resource block group selected from the target mapping relationship as the frequency domain resource used by the user equipment can be determined through the first control information sent by the network side.

[0059] The first control information can be the control information transmitted by the physical downlink control channel. The specific content of the first control information can be the identification information indicating the resource block group, and the identification information of the resource block group can be information known by both the user equipment and the network side.

[0060] Alternatively, the specific content of the first control information can also be the size of the bandwidth part to be used by the user equipment, so that the user equipment determines the size of the resource block group to be used by itself according to the size of the bandwidth part.

[0061] Alternatively, the specific content of the first control information can also be the size of the resource block group to be used by the user equipment directly indicated by the network side.

[0062] It can be seen that, by using the foregoing scheme, the user equipment can determine the target mapping relationship based on at least two candidate mapping table relationships, and then determine the frequency domain resource to be used through the control information sent by the network side; and the at least two candidate mapping relationships can include the first mapping relationship in which different BWP ranges are mapped to different RBG sizes and the second mapping relationship in which the same RBG size is used. In this way, the multiple mapping relationships can be flexibly used to allocate the frequency domain resource for the user equipment, so that the scheduling flexibility is obtained, and the scheduling complexity of the base station and the operation complexity of the terminal are reduced.

[0063] Embodiment two,

[0064] The embodiment of the application provides a resource indication method applied to a network device, which comprises the following steps:

[0065] sending first control information to the user equipment, wherein the first control information is used to indicate that the user equipment allocates the frequency domain resource according to the size of the target resource block group in the target mapping relationship;

[0066] The target mapping relationship is one of at least two candidate mapping relationships, and the at least two candidate mapping relationships at least include a first mapping relationship and a second mapping relationship; in the first mapping relationship, each group of bandwidth part size ranges maps a different resource block group size; and in the second mapping relationship, at least two groups of bandwidth part size ranges can map to the same resource block group size.

[0067] The network device provided in the embodiment can be a base station on a network side or other device capable of transmitting control signaling and configuration signaling with a user equipment.

[0068] As to the two mapping relationships, refer to Table 2:

[0069]

[0070] Table 2

[0071] As can be seen from Table 2, in the first mapping relationship, different bandwidth part size ranges correspond to different resource block group sizes, for example, in Table 2, the mapped resource block group sizes are 1, 2, 4, 8 and 16 respectively; and in the second mapping relationship, multiple different bandwidth part sizes correspond to the same resource block group size, for example, in Table 2, three bandwidth part size ranges correspond to the same resource block group size, which is 4, and the remaining two bandwidth part size ranges correspond to another resource block group size, which is 16. In addition, the size range of BWP in the table can be set according to actual conditions, and the table is only an example, which is not exhaustive here.

[0072] Here, the target mapping relationship can be the first mapping relationship or the second mapping relationship.

[0073] It should also be understood that there can be more mapping relationships in practice, but they are not exhaustive in the embodiment.

[0074] The at least two candidate mapping relationships can be at least two candidate mapping relationships preset in the user equipment, or can be at least two candidate mapping relationships configured by the network device to the user equipment.

[0075] The at least two candidate mapping relationships can be obtained from radio resource control (RRC) configuration information, or can be obtained from other information.

[0076] Specifically, the manner of selecting the target mapping relationship from the at least two candidate mapping relationships can be that first configuration signaling is sent to the user equipment, and the first configuration signaling is used to instruct the user equipment to select the target mapping relationship from the at least two mapping relationships.

[0077] The first configuration signaling can be acquired through RRC configuration information. In the first configuration signaling, the capability information of the network side can be included, so that the user equipment determines which target mapping relationship is selected from at least two candidate mapping relationships according to the first configuration signaling. For example, when the capability of the network side (base station) represents that the load capability is low, the second mapping relationship can be selected as the target mapping relationship, and vice versa, the first mapping relationship can be selected as the target mapping relationship.

[0078] In addition, the target mapping relationship that the user equipment needs to select can be acquired in the first configuration signaling. In this way, the network side (that is, the base station) can determine whether the capability of the network side can bear a larger load. If yes, the user equipment can be notified to select the first mapping relationship as the target mapping relationship through the first configuration signaling; otherwise, the user equipment can be notified to select the second mapping relationship as the target mapping relationship through the first configuration signaling.

[0079] The first control information in the embodiment can be control information transmitted by a physical downlink control channel. The specific content of the first control information can be identification information indicating a resource block group. The identification information of the resource block group can be information known by both the user equipment and the network equipment.

[0080] Alternatively, the specific content of the first control information can also be the size of the bandwidth part to be used by the user equipment, so that the user equipment determines the size of the resource block group to be used by the user equipment according to the size of the bandwidth part.

[0081] Alternatively, the specific content of the first control information can also be the size of the resource block group to be used by the user equipment directly indicated by the network equipment.

[0082] It can be seen that by using the above scheme, the user equipment can determine the target mapping relationship based on at least two candidate mapping table relationships, and then determine the frequency domain resource to be used through the control information sent by the network side. In the at least two candidate mapping relationships, the first mapping relationship of different BWP range mapping to different RBG size and the second mapping relationship of same RBG size can be included. In this way, the multiple mapping relationships can be flexibly used to allocate frequency domain resources for the user equipment, so that the scheduling flexibility is obtained, and the scheduling complexity of the base station and the operation complexity of the terminal are reduced.

[0083] Embodiment three,

[0084] The embodiment of the application provides a user equipment, as shown in the figure, Figure 2 comprising:

[0085] The first processing unit 21 selects a target mapping relationship from at least two candidate mapping relationships; determines the size of a target resource block group according to the bandwidth part size range in the target mapping relationship; and allocates frequency domain resources according to the size of the target resource block group and the first control information sent by the network side; wherein the at least two candidate mapping relationships include at least a first mapping relationship and a second mapping relationship; in the first mapping relationship, each bandwidth part size range maps a different resource block group size; and in the second mapping relationship, at least two bandwidth part size ranges can map to the same resource block group size.

[0086] The first communication unit 22 receives the first control information sent by the network side.

[0087] For the two mapping relationships, refer to Table 2:

[0088]

[0089] Table 2

[0090] As can be seen from Table 2, in the first mapping relationship, different bandwidth part size ranges correspond to different resource block group sizes, for example, in Table 2, the mapped resource block group sizes are 1, 2, 4, 8, and 16, respectively; and in the second mapping relationship, multiple different bandwidth part sizes correspond to the same resource block group size, for example, in Table 2, three bandwidth part size ranges correspond to the same resource block group size, which is 4, and the remaining two bandwidth part size ranges correspond to another resource block group size, which is 16. In addition, the size range of BWP in the table can be set according to actual conditions, and the table is only an example, and therefore, it is not exhaustive here.

[0091] Here, the target mapping relationship can be the first mapping relationship or the second mapping relationship.

[0092] It should also be understood that there can be more mapping relationships in practice, but they are not exhaustive in this embodiment.

[0093] The at least two candidate mapping relationships can be at least two candidate mapping relationships preset in the user equipment, or the first communication unit 22 can obtain the at least two candidate mapping relationships from the network side.

[0094] The at least two candidate mapping relationships obtained from the network side can be obtained from radio resource control (RRC) configuration information, or can be obtained from other information.

[0095] Specifically, selecting the target mapping relationship from the at least two candidate mapping relationships includes:

[0096] The first communication unit 22 receives first configuration signaling sent by the network side; the first processing unit 21 selects a target mapping relationship from at least two candidate mapping relationships according to the first configuration signaling sent by the network side.

[0097] Or,

[0098] The first processing unit 21 selects a target mapping relationship from at least two candidate mapping relationships according to a preset rule.

[0099] The first configuration signaling can be obtained through RRC configuration information. In the first configuration signaling, the capability information of the network side can be included, so that the user equipment determines which target mapping relationship is selected from the at least two candidate mapping relationships according to the first configuration signaling. For example, when the capability of the network side (base station) represents that the load capacity is low, the second mapping relationship can be selected as the target mapping relationship, and vice versa, the first mapping relationship can be selected as the target mapping relationship.

[0100] In addition, the target mapping relationship that the user equipment needs to select can be obtained in the first configuration signaling. In this way, the network side (that is, the base station) can judge whether its own capability can bear a larger load. If so, the user equipment can be notified through the first configuration signaling to select the first mapping relationship as the target mapping relationship; otherwise, the user equipment can be notified through the first configuration signaling to select the second mapping relationship as the target mapping relationship.

[0101] The target mapping relationship is selected from at least two candidate mapping relationships according to a preset rule. The preset rule can be determined according to the system load detected by the user equipment, for example, when the system load is detected to be large, the second mapping relationship can be selected as the target mapping relationship, and vice versa, the first mapping relationship can be selected as the target mapping relationship. The system load can be obtained through the system load information sent by the network side, and the specific sending method is not described in this embodiment.

[0102] In addition, the quality of the reference signal of the network side detected by the user equipment can also be used for judgment, for example, when the quality of the reference signal of the network side is detected to be poor, the second mapping relationship can be selected as the target mapping relationship, and vice versa, the first mapping relationship can be selected as the target mapping relationship.

[0103] The judgment method of the quality of the reference signal can be that the interference is less than the preset interference threshold value, which means that the quality is good, and vice versa. Or, the signal-to-noise ratio is higher than the preset signal-to-noise ratio threshold value, which means that the quality is good, and vice versa. It should be understood that there can be other judgment methods, which are not exhaustively described in this embodiment.

[0104] According to the bandwidth part size range in the target mapping relationship, the size of the target resource block group is determined; referring to the foregoing Table 2, when the target mapping relationship is determined, the sizes of the multiple resource block groups corresponding to the multiple bandwidth part size ranges of the user equipment can be known.

[0105] Further, the first processing unit 21 can determine which size of the resource block group is selected from the target mapping relationship as the frequency domain resource used by the user equipment through the first control information sent by the network side.

[0106] The first control information can be control information transmitted by a physical downlink control channel. The specific content of the first control information can be identification information indicating the resource block group. The identification information of the resource block group can be information known by both the user equipment and the network side.

[0107] Alternatively, the specific content of the first control information can also be the size of the bandwidth part to be used by the user equipment, so that the user equipment determines the size of the resource block group to be used by itself according to the size of the bandwidth part.

[0108] Alternatively, the specific content of the first control information can also be the size of the resource block group to be used by the user equipment directly indicated by the network side.

[0109] It can be seen that by using the foregoing scheme, the user equipment can determine the target mapping relationship based on at least two candidate mapping table relationships, and then determine the frequency domain resource to be used through the control information sent by the network side. In the at least two candidate mapping relationships, the first mapping relationship in which different BWP ranges are mapped to different RBG sizes and the second mapping relationship in which the same RBG size is included. In this way, the multiple mapping relationships can be flexibly used to allocate frequency domain resources for the user equipment, so that scheduling flexibility is obtained, and the scheduling complexity of the base station and the operation complexity of the terminal are reduced.

[0110] Embodiment four,

[0111] The embodiment of the application provides a network device, such as Figure 3 as shown, comprising:

[0112] The second communication unit 31 sends the first control information to the user equipment, wherein the first control information is used to indicate that the user equipment allocates the frequency domain resource according to the size of the target resource block group in the target mapping relationship.

[0113] The target mapping relationship is one of at least two candidate mapping relationships, and the at least two candidate mapping relationships at least include a first mapping relationship and a second mapping relationship; in the first mapping relationship, each group of bandwidth part size ranges maps a different resource block group size; and in the second mapping relationship, at least two groups of bandwidth part size ranges can map to the same resource block group size.

[0114] The network device provided in the embodiment can be a base station on a network side or other device capable of transmitting control signaling and configuration signaling with a user equipment.

[0115] As to the two mapping relationships, refer to Table 2:

[0116]

[0117]

[0118] Table 2

[0119] As can be seen from Table 2, in the first mapping relationship, different bandwidth part size ranges correspond to different resource block group sizes, for example, in Table 2, the mapped resource block group sizes are 1, 2, 4, 8 and 16 respectively; and in the second mapping relationship, multiple different bandwidth part sizes correspond to the same resource block group size, for example, in Table 2, three bandwidth part size ranges correspond to the same resource block group size, which is 4, and the remaining two bandwidth part size ranges correspond to another resource block group size, which is 16. In addition, the size range of BWP in the table can be set according to actual conditions, and the table is only an example, which is not exhaustive here.

[0120] Here, the target mapping relationship can be the first mapping relationship or the second mapping relationship.

[0121] It should also be understood that there can be more mapping relationships in practice, but they are not exhaustive in the embodiment.

[0122] The at least two candidate mapping relationships can be at least two candidate mapping relationships preset in the user equipment, or the network device can configure at least two candidate mapping relationships for the user equipment, that is, the network device further includes:

[0123] The second processing unit 32 determines the at least two candidate mapping relationships;

[0124] The second communication unit 31 configures at least two candidate mapping relationships for the user equipment.

[0125] The second communication unit 31 can send the user equipment the manner of the at least two candidate mapping relations, which can be obtained from radio resource control (RRC) configuration information, or from other information.

[0126] Specifically, the second communication unit 31 can send the user equipment a first configuration signaling, which is used to instruct the user equipment to select a target mapping relation from the at least two mapping relations.

[0127] The first configuration signaling can be obtained from RRC configuration information. The network side capability information can be included in the first configuration signaling, so that the user equipment can determine which target mapping relation to select from the at least two candidate mapping relations according to the first configuration signaling. For example, when the network side (base station) has a low load capability, the second mapping relation can be selected as the target mapping relation, and vice versa.

[0128] In addition, the network side can indicate the target mapping relation that the user equipment needs to select in the first configuration signaling. In this way, the network side (i.e., the base station) can determine whether it can bear a large load, and if so, it can instruct the user equipment to select the first mapping relation as the target mapping relation through the first configuration signaling; otherwise, it can instruct the user equipment to select the second mapping relation as the target mapping relation through the first configuration signaling.

[0129] The first control information in this embodiment can be control information transmitted by a physical downlink control channel. The specific content can be identification information corresponding to the resource block group. The identification information of the resource block group can be information known to both the user equipment and the network equipment.

[0130] Alternatively, the specific content of the first control information can be the size of the bandwidth to be used by the user equipment, so that the user equipment can determine the size of the resource block group to be used according to the size of the bandwidth.

[0131] Alternatively, the specific content of the first control information can be the size of the resource block group to be used by the user equipment, which is directly indicated by the network equipment.

[0132] It can be seen that by using the above scheme, the user equipment can determine the target mapping relationship based on at least two candidate mapping table relationships, and then determine the frequency domain resources to be used through the control information sent by the network side; and the at least two candidate mapping relationships can include a first mapping relationship in which different BWP ranges are mapped to different RBG sizes and a second mapping relationship in which the same RBG size is used. In this way, the multiple mapping relationships can be flexibly used to allocate frequency domain resources to the user equipment, so that scheduling flexibility is obtained, and the scheduling complexity of the base station and the operation complexity of the terminal are reduced.
