Description

[0001] Cross-referencing

[0002] This disclosure is part of a non-provisional application that claims priority to U.S. Patent Application No. 63 / 500,929, filed May 9, 2023, the contents of which are incorporated herein by reference in their entirety. [Technical Field]

[0003] This disclosure relates to mobile communications, and particularly to frequency domain resource allocation (FDRA) of a mobile communication device on discontinuous subbands in sub-band full duplex (SBFD). [Background Technology]

[0004] Unless otherwise stated herein, the methods described in this section are not prior art to the following claims and are not acknowledged as prior art simply because they are not included in this section.

[0005] In 5G New Radio (NR) mobile communication, sub-band full-duplex (SBFD) technology has been introduced. Typically, discontinuous subbands can be configured within a single time slot. For example, two discontinuous downlink subbands and one uplink subband located between the discontinuous downlink subbands can be configured within a single time slot, or two discontinuous uplink subbands and one downlink subband located between the discontinuous uplink subbands can be configured within a single time slot.

[0006] However, regarding the physical downlink shared channel (PDSCH) and physical uplink shared channel (PUSCH), traditional frequency domain resource allocation (FDRA), particularly resource allocation type 1 which uses resource indication values ​​(RIVs) to configure a set of virtual resource blocks (VRBs), may not be suitable for resource allocation across discontinuous subbands in SBFD. More specifically, there is no solution for allocating VRBs and physical resource blocks (PRBs) configured in traditional FDRA across discontinuous subbands in SBFD.

[0007] Therefore, how to apply FDRA across discontinuous subbands in SBFD, and how to correctly allocate VRBs and PRBs across discontinuous subbands in SBFD, has become an important issue in newly developed wireless communication networks. Thus, a suitable scheme is needed to apply FDRA across discontinuous subbands in SBFD. [Summary of the Invention]

[0008] The following summary is illustrative only and is not intended to be limiting in any way. That is, the summary aims to introduce the concepts, highlights, benefits, and advantages of the novel and non-obvious techniques described herein. Selected embodiments will be further illustrated in the detailed description. Therefore, the following summary is not intended to identify the essential features of the claimed claims, nor is it intended to determine the scope of the claimed claims.

[0009] The objective of this disclosure is to propose a solution or scheme to address the aforementioned problems related to frequency domain resource allocation (FDRA) on discontinuous subbands in sub-band full duplex (SBFD) associated with mobile communication devices.

[0010] In one aspect, one approach may involve the device receiving SBFD configuration and FDRA configuration from a network node. The SBFD configuration comprises discontinuous subbands within a time slot, while the FDRA configuration comprises multiple resource blocks (RBs). This approach may also involve the device receiving information from the network node indicating that a subset of RBs located outside the discontinuous subbands has been excluded.

[0011] In one aspect, one approach may involve the device sending SBFD configuration and FDRA configuration to the user equipment (UE). The SBFD configuration includes discontinuous subbands within a time slot, while the FDRA configuration includes multiple RBs. This approach may also involve the device sending information to the UE indicating to the UE that a subset of RBs located outside the discontinuous subbands has been excluded.

[0012] In one aspect, the apparatus may include a transceiver that wirelessly communicates with at least one network node of a wireless network during operation. The apparatus may also include a processor communicatively connected to the transceiver. Operations that the processor may perform during operation include receiving SBFD configuration and FDRA configuration from the network node via the transceiver. The SBFD configuration includes discontinuous subbands within a time slot, while the FDRA configuration includes a plurality of RBs. Further operations that the processor may perform include receiving information from the network node via the transceiver. This information indicates to the apparatus that a subset of RBs located outside the discontinuous subbands has been excluded.

[0013] In one aspect, the apparatus may include a transceiver that wirelessly communicates with at least one UE of a wireless network during operation. The apparatus may also include a processor communicatively connected to the transceiver. Operations that the processor may perform during operation include transmitting SBFD configuration and FDRA configuration to the UE via the transceiver. The SBFD configuration includes discontinuous subbands within a time slot, while the FDRA configuration includes multiple RBs. Further operations that the processor may perform include transmitting information to the UE via the transceiver. This information indicates to the UE that a subset of RBs located outside the discontinuous subbands has been excluded.

[0014] It is worth noting that although the descriptions provided herein may be made within the context of certain wireless access technologies, networks, and network topologies (such as Long-Term Evolution (LTE), LTE-Advanced, LTE-Advanced Pro, 5th Generation (5G), New Radio (NR), Internet-of-Things (IoT), Narrow Band Internet of Things (NB-IoT), Industrial Internet of Things (IIoT), and 6th Generation (6G)), the proposed concepts, schemes, and any variations / derivatives thereof can be implemented in other types of wireless access technologies, networks, and network topologies.

Detailed Implementation Methods

[0031] This document discloses detailed embodiments and implementations of the claimed claims. However, it should be understood that the disclosed embodiments and implementations are merely illustrative examples of the claimed claims and may be embodied in various forms. This disclosure may be embodied in many different forms and should not be construed as limited to the exemplary embodiments and implementations described herein. Rather, these exemplary embodiments and implementations are intended to make the description of this disclosure comprehensive and complete, and to fully convey the scope of this disclosure to those skilled in the art. Details of well-known features and techniques may be omitted in the following description to avoid unnecessarily obscuring the presented embodiments and implementations.

[0032] Overview

[0033] The embodiments disclosed herein relate to various techniques, methods, schemes, and / or solutions for frequency domain resource allocation (FDRA) on discontinuous subbands in sub-band full-duplex (SBFD) associated with mobile communication devices. According to this disclosure, many possible solutions can be implemented individually or in combination. That is, although these possible solutions may be described individually below, two or more of these possible solutions may be implemented in some combination.

[0034] Regarding this disclosure, allocating resource blocks (RBs) across discontinuous subbands (SBs) in SBFD may allow FDRA, particularly type 1 FDRA. Specifically, RBs can be allocated across discontinuous subbands by excluding RBs outside of discontinuous subbands in SBFD.

[0035] Figure 1 Example scenario 100 is illustrated under the scheme of the embodiments disclosed herein. Scenario 100 involves at least one network node and a user equipment (UE), which may be part of a wireless communication network (e.g., an LTE network, a 5G / NR network, an IoT network, or a 6G network). Scenario 100 illustrates a current network framework. The UE may be connected to the network side. The network side may include one or more network nodes.

[0036] In some embodiments, a network node may send an SBFD configuration and an FDRA configuration to the UE. The SBFD configuration may include discontinuous subbands within a time slot, and the FDRA configuration may include multiple Resource Blocks (RBs). In other words, the SBFD configuration may include parameters indicating discontinuous subbands within a time slot, and the FDRA configuration may include parameters indicating RBs. The network node may send a message to the UE instructing the UE that a subset of RBs outside the discontinuous subbands should be excluded. Upon receiving the SBFD configuration, FDRA configuration, and this message, the UE may apply the SBFD and FDRA configurations and determine that a subset of RBs outside the discontinuous subbands should be excluded.

[0037] Figure 2Example scenario 200 under the scheme according to the embodiments of this disclosure is illustrated. In some embodiments, the SBFD configuration may include parameters indicating two discontinuous downlink (DL) subbands and one uplink (UL) subband within a time slot, wherein the UL subband is located between the DL subbands. The FDRA configuration may include parameters indicating RBs. Information may indicate to the UE that a subset of RBs outside the discontinuous DL subbands is excluded. In other words, in these embodiments, a subset of RBs located within the UL subband is excluded.

[0038] In some implementations, a subset of RBs can be excluded by reindexing (i.e. renumbering) the virtual resource blocks (VRBs) and physical resource blocks (PRBs) corresponding to RBs. Figure 3 Example scenario 300 under the scheme according to the embodiments of this disclosure is illustrated. For example, RBs include VRBs and / or PRBs of the DL bandwidth part (BWP), and the VRBs and / or PRBs are reindexed to exclude VRBs and / or PRBs outside of discontinuous DL subbands. In other words, the VRBs and / or PRBs of the DL BWP are reindexed to exclude VRBs and / or PRBs located in the UL subbands (and guardband—if configured) between discontinuous DL subbands.

[0039] In these implementations, to exclude VRBs located within the UL subband (i.e., original VRBs #4 and #5), original VRBs #0 to #3 and #6 to #9 are reindexed as VRBs #0 to #7 so that the reindexed VRBs are continuous between discontinuous DL subbands. Similarly, to exclude PRBs located within the UL subband (i.e., original PRBs #4 and #5), original PRBs #0 to #3 and #6 to #9 are reindexed as PRBs #0 to #7 so that the reindexed PRBs are continuous between discontinuous DL subbands. Therefore, the VRB-to-PRB interleaving process avoids referencing PRBs outside the DL subband.

[0040] When VRBs and / or PRBs are reindexed on a time slot, a subset of bits in the frequency domain allocation field provides (i.e., is used) resource allocation. Different resource allocation types (e.g., type "0", type "1", and type "dynamicswitch" configured by the higher-level parameter resourceAllocation, as specified in the 3GPP specification) may correspond to different formats of the frequency domain allocation field.

[0041] In some implementations, regarding resource allocation type "1", the information can be downlink control information (DCI) containing a frequency domain allocation field, and: (1) a first subset of bits in the frequency domain allocation field can be used to indicate a resource allocation; (2) a second subset of bits in the frequency domain allocation field is not used for resource allocation. In some cases, (1) the first bit of the first subset of bits corresponds to the number of RBs across subbands; (2) the second bit of the second subset of bits corresponds to the difference between the first bit of the first subset of bits and the third bit corresponding to the number of all RBs on the BWP.

[0042] Figure 4 Example scenario 400 under the scheme according to the implementation of this disclosure is described. For example, regarding the frequency domain allocation field of resource allocation type "1", X1 represents the bit field length corresponding to all RBs on the DL BWP (i.e., X1 represents the third bit corresponding to the number of all RBs on the DL BWP), and Y1 most significant bits (MSBs) of the frequency domain allocation field (in the X1 bits) are provided (i.e. used) for resource allocation (i.e., Y1 represents the number of RBs across the DL subband corresponding to the first bit of the first subset bits). Therefore, the remaining (X1-Y1) least significant bits (LSBs) of the frequency domain allocation field are not used for resource allocation (i.e., (X1-Y1) represents the difference between the first bit of the first subset bits and the third bit corresponding to the number of all RBs on the DL BWP).

[0043] In some cases,

[0044]

[0045]

[0046] in It is the number of RBs in DL BWP. N is the number of RBs in the i-th DL SB. DL-SB It represents the number of DL SBs.

[0047] In some embodiments, regarding resource allocation type "0", this information can be a DCI containing a frequency domain allocation field, and: (1) a first subset of bits of this frequency domain allocation field can be used to indicate resource allocation; and (2) a second subset of bits of this frequency domain allocation field is not used for resource allocation. In some cases, (1) the first bit of the first subset of bits corresponds to the number of resource module groups (RGBs) across SBs; and (2) the second bit of the second subset of bits corresponds to the difference between the first bit of the first subset of bits and the third bit corresponding to the number of all RGBs on the BWP.

[0048] Figure 5 Example scenario 500 under the scheme of the embodiment according to this disclosure is illustrated. For example, regarding the frequency domain allocation field of resource allocation type "0", X0 represents the bit field length corresponding to all RGBs on the DL BWP (i.e., X0 represents the third bit corresponding to the number of all RBs on the DL BWP), and Y0 MSBs in the frequency domain allocation field (in X0 bits) are provided (i.e., used for) resource allocation (i.e., Y0 represents the first bit of the first subset of bits corresponding to the number of RGBs across DL SBs). Therefore, the remaining (X0-Y0) LSBs of the frequency domain allocation field are not used for resource allocation (i.e., (X0-Y0) represents the difference between the second bit of the second subset of bits corresponding to the first bit of the first subset of bits and the third bit corresponding to the number of all RGBs on the DL BWP).

[0049] In some cases,

[0050]

[0051]

[0052] in It is the size of the DL BWP. It is the starting RB of DL BWP. It is the number of RBs in the i-th DL SB. Let be the starting RB of the i-th DL SB, and P be the number of RBs in each RGB.

[0053] Figure 6Example scenario 600 is illustrated under the scheme of the embodiments according to this disclosure. In some embodiments, regarding the frequency domain allocation field corresponding to the resource allocation type "dynamic switching" (i.e., resource allocation type "0" and type "1" are configured), this frequency domain allocation field can be interpreted as follows: (1) the MSB of this frequency domain allocation field is used to indicate the resource allocation type (i.e., "0" represents type "0", and "1" represents type 1); (2) when resource allocation type "0" is indicated (i.e., the bit value of the MSB is "0"), the next Y0 bits of this frequency domain allocation field are provided (i.e., used for) resource allocation, and the remaining ([max(X0,X1)+1]-Y0) LSBs of this frequency domain allocation field are not used for resource allocation; (3) when resource allocation type "1" is indicated (i.e., the bit value of the MSB is "1"), the next Y1 bits of this frequency domain allocation field are provided (i.e., used for) resource allocation, and the remaining ([max(X0,X1)+1]-Y1) LSBs of this frequency domain allocation field are not used for resource allocation. In these embodiments, X0, Y0, X1, and Y1 can be calculated with reference to formulas (1) to (4) above. It should be noted that max(X0,X1) is defined as the maximum value of X0 and X1.

[0054] Figure 7 An example scenario 700 of a scheme according to an embodiment of this disclosure is illustrated. In some embodiments, the Subband Full-Duplex (SBFD) configuration may include parameters indicating two discontinuous uplink subbands (UL SBs) and a downlink subband (DL SB) located between the UL SBs within a time slot. The Frequency Domain Resource Allocation (FDRA) configuration may include parameters indicating resource modules (RBs). This information may indicate to the User Equipment (UE) that a subset of RBs located outside the discontinuous UL SBs is excluded. In these embodiments, a subset of RBs located within the DL SB (and the guardband—if a guardband is configured) is excluded.

[0055] In some embodiments, a subset of RBs can be excluded by re-indexing (i.e. re-numbering) the virtual resource modules (VRBs) and physical resource modules (PRBs) corresponding to RBs. Figure 8 An example scenario 800 of a scheme according to an embodiment of this disclosure is illustrated. For example, RBs include VRBs and / or PRBs of the UL bandwidth portion (UL BWP), and these VRBs and / or PRBs are reindexed to exclude VRBs and / or PRBs located outside of discontinuous UL SBs. In other words, the VRBs and / or PRBs of the UL BWP are reindexed to exclude VRBs and PRBs located within DL SBs between discontinuous UL SBs.

[0056] In these embodiments, to exclude VRBs located within the DL SB (i.e., the original VRBs #4 and #5), the original VRBs #0 to #3 and #6 to #9 are reindexed as VRBs #0 to #7, such that the reindexed VRBs are continuous between discontinuous UL SBs. Similarly, to exclude PRBs located within the DL SB (i.e., the original PRBs #4 and #5), the original PRBs #0 to #3 and #6 to #9 are reindexed as PRBs #0 to #7, such that the reindexed PRBs are continuous between discontinuous UL SBs. Therefore, the VRB-to-PRB interleaving process avoids referencing PRBs located outside the UL SBs.

[0057] When VRBs and / or PRBs are reindexed on a time slot with discontinuous UL SBs, a subset of bits in the frequency domain allocation field provides (i.e., for) resource allocation. Different resource allocation types (e.g., type "0", type "1", and type "Dynamic Switching" configured by the higher-level parameter resourceAllocation, as described in the 3GPP specification) can correspond to different formats of the frequency domain allocation field.

[0058] In some embodiments, regarding resource allocation type "1" and when frequency hopping is disabled, this information may be downlink control information (DCI) including a frequency domain allocation field, and: (1) a first subset of bits in the frequency domain allocation field is used to indicate the resource allocation; and (2) a second subset of bits in the frequency domain allocation field is not used for the resource allocation. In some cases, (1) the first bit of the first subset of bits corresponds to the number of RBs across subbands; and (2) the second bit of the second subset of bits corresponds to the difference between the first bit of the first subset of bits and the third bit corresponding to the number of all RBs on the bandwidth portion (BWP).

[0059] Figure 9 An example scenario 900 of the scheme according to an embodiment of this disclosure is shown. For example, regarding the frequency domain allocation field of resource allocation type "1", and when the frequency hopping function is disabled, X1 represents the bit field length corresponding to all RBs on the UL BWP (i.e., X1 represents the third bit corresponding to the number of all RBs on the UL BWP), and the Y1 most significant bits of the frequency domain allocation field (in the X1 bits) are provided (i.e., used for) resource allocation (i.e., Y1 represents the first bit of the first subset bits corresponding to the number of RBs across UL SBs). Therefore, the remaining (X1-Y1) least significant bits of the frequency domain allocation field are not used for resource allocation (i.e., X1-Y1 represents the second bit of the second subset bits corresponding to the difference between the first bit of the first subset bits and the third bit corresponding to the number of all RBs on the UL BWP).

[0060] In some cases,

[0061]

[0062]

[0063] in, It is the number of RBs in the UL BWP. N is the number of RBs in the i-th UL SB. UL-SB This refers to the number of UL SBs.

[0064] In some embodiments, regarding the frequency domain allocation field corresponding to resource allocation type "1" and when the frequency hopping function is enabled, this information may be a DCI containing the frequency domain allocation field, and: (1) a first subset of bits of the frequency domain allocation field is used to indicate the resource allocation; and (2) a second subset of bits of the frequency domain allocation field is not used for the resource allocation. In some cases, (1) the first bit of the first subset of bits corresponds to the number of RBs across subbands; and (2) the third bit corresponds to the number of all RBs on the bandwidth portion (BWP).

[0065] Figure 10 An example scenario 1000 under the scheme according to the embodiments of this disclosure is shown. For example, regarding the frequency domain allocation field and enabling frequency hopping function of resource allocation type "1", X1 represents the bit field length corresponding to all RBs on the UL BWP (i.e., X1 represents the third bit corresponding to the number of all RBs on the UL BWP), Y1 MSBs of the frequency domain allocation field (in X1 bits) provide (i.e., for) resource allocation (i.e., Y1 represents the number of RBs across UL SBs corresponding to the first bit of the first subset of bits), and N of the frequency domain allocation field UL_hop One MSB bit is used to indicate the frequency offset of the frequency hopping function. Therefore, the remaining (X1-Y1-N) bits in the frequency domain allocation field UL_hop ) LSBs are not used for resource allocation (i.e., (X1-Y1-N) UL_hop () represents the second bit of the second subset). In these embodiments, the calculation of X1 and Y1 can be referred to formulas (5) and (6) above.

[0066] In some embodiments, regarding the frequency domain allocation field corresponding to resource allocation type 0, the information may be a DCI containing the frequency domain allocation field, and: (1) a first subset of bits of the frequency domain allocation field may be used to indicate resource allocation; (2) a second subset of bits of the frequency domain allocation field may not be used for resource allocation. In some cases, (1) the first bit of the first subset of bits corresponds to the number of RBGs across SBs; (2) the second bit of the second subset of bits corresponds to the difference between the first bit of the first subset of bits and the third bit corresponding to the number of all RBGs on the BWP.

[0067] Figure 11 An example scenario 1100 under the scheme according to the embodiments of this disclosure is shown. For example, regarding the frequency domain allocation field of resource allocation type "0", X0 represents the bit field length corresponding to all RBGs on the UL BWP (i.e., X0 represents the third bit corresponding to the number of all RBs on the UL BWP), and Y0 MSBs of the frequency domain allocation field (in X0 bits) are provided (i.e., used for) resource allocation (i.e., Y0 represents the number of RBGs across UL SBs corresponding to the first bit of the first subset of bits). Therefore, the remaining (X0-Y0) LSBs of the frequency domain allocation field are not used for resource allocation (i.e., (X0-Y0) represents the difference between the first bit of the first subset of bits and the third bit corresponding to the number of all RBGs on the UL BWP).

[0071] in It is the size of a UL BWP. It is the starting RB of UL BWP. It is the number of RBs in the i-th UL SB. Let RB be the starting RB of the i-th UL SB, and P be the number of RBs in each RBG.

[0072] Figure 12An example scenario 1200 under the scheme according to the embodiments of this disclosure is shown. In some embodiments, regarding the frequency domain allocation field corresponding to the resource allocation type "dynamic switching" (i.e., configuring resource allocation type "0" and type "1" simultaneously), the frequency domain allocation field can be interpreted as follows: (1) the MSB of the frequency domain allocation field is used to indicate the resource allocation type (i.e., type "0" is "0", and type "1" is "1"); (2) when the resource allocation type "0" is indicated (i.e., the bit value of the MSB is "0"), the next Y0 bits of the frequency domain allocation field are provided (i.e., used for) resource allocation, and the remaining ([max(X0,X1)+1]-Y0) LSBs of the frequency domain allocation field are not used for resource allocation; (3) when the resource allocation type "1" is indicated (i.e., the bit value of the MSB is "1"), the next Y1 bits of the frequency domain allocation field are provided (i.e., used for) resource allocation, and the remaining ([max(X0,X1)+1]-Y1) LSBs of the frequency domain allocation field are not used for resource allocation. In these embodiments, the calculation of X0, Y0, X1, and Y1 can be referred to formulas (5) to (8) above. It should be noted that max(X0,X1) is defined as the maximum value of X0 and X1.

[0073] In some embodiments, the encoding rules for RIVs of resource allocation type "1" may be adjusted due to the re-indexing of PRBs. In some embodiments, the encoding rules for RIVs are adjusted as follows:

[0121] Additional Notes

[0122] The topics described herein sometimes illustrate different components contained within or connected to different other components. It should be understood that the architectures shown are merely examples, and many other architectures can actually be implemented to achieve the same functionality. Conceptually, any arrangement of components to achieve the same functionality is actually “associated” in order to achieve the desired functionality. Therefore, any two components combined in this document to achieve a particular function can be considered “associated” in order to achieve the desired functionality, regardless of the architecture or intermediate components. Similarly, any two such associated components can also be considered “operationally connected” or “operationally coupled” to achieve the desired functionality, and any two components that can be suchly associated can also be considered “operationally coupled” to achieve the desired functionality. Specific examples of operational coupling include, but are not limited to, physically connectable and / or physically interactive components and / or wirelessly interactive and / or logically interactive components.

[0123] Furthermore, regarding the use of virtually any plural and / or singular terms in this document, a person with technical skills may appropriately translate from plural to singular and / or from singular to plural depending on the context and / or application. For clarity, various singular / plural permutations may be explicitly listed in this document.

[0124] Furthermore, those skilled in the art will understand that terms commonly used herein, particularly in appended claims, such as the body of an appended claim, are generally considered "open" terms. For example, the word "comprising" should be interpreted as "including but not limited to," the word "having" should be interpreted as "having at least," and the word "including" should be interpreted as "including but not limited to," etc. Those skilled in the art will also further understand that if a specific number of statements are explicitly introduced in a claim, this intention is explicitly stated in the claim, and where there is no such statement, this intention does not exist. For example, to aid understanding, the following appended claims may contain the use of the introductory phrases "at least one" and "one or more" to introduce claim statements. However, the use of these phrases should not be construed as implying that introducing claim statements with the indefinite article "a (a or an)" limits any particular claim containing such an introductory claim statement to containing only one such statement, even if the same claim includes the introductory phrase "one or more" or "at least one" and the indefinite article such as "a (a or an)," for example, "a (a or an)" should be interpreted as "at least one" or "one or more"; the same applies to definite articles used to introduce claim statements. Furthermore, even when a specific number of claims is explicitly stated, those skilled in the art will recognize that such a statement should be interpreted as at least the stated number. For example, the simple statement "two statements" without any other modifiers means at least two statements, or two or more statements. Additionally, when using conventions such as "at least one A, B, and C," this structure is generally understood by those skilled in the art to mean the convention. For example, "a system having at least one A, B, and C" will include, but is not limited to, a system having only A, a system having only B, a system having only C, a system with A and B together, a system with A and C together, a system with B and C together, and / or a system with A, B, and C together, etc. Similarly, when using conventions such as "at least one A, B, or C," this structure is generally understood by those skilled in the art to mean the convention. For example, "a system having at least one A, B, or C" will include, but is not limited to, a system having only A, a system having only B, a system having only C, a system with A and B together, a system with A and C together, a system with B and C together, and / or a system with A, B, and C together, etc. Those skilled in the art will further understand that virtually any extractive word and / or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to include the possibility of containing one term, two terms, or both terms. For example, the phrase "A or B" would be understood to include the possibility of "A" or "B" or "A and B".
