Description

Technical Field

[0001] The present invention relates to the field of wireless technology, and in particular to a method, apparatus, terminal, network equipment and storage medium for determining frequency domain resources. Background Art

[0002] Subband non-overlapping Full Duplex (SBFD) combines the characteristics of TDD and Frequency Division Duplex (FDD). By dividing the carrier bandwidth into several "subbands" with non-overlapping frequency domains, the base station can simultaneously perform uplink reception in the uplink subband (UL subband) and downlink transmission in the downlink subband (DL subband). For time slots / symbols configured with subbands, they can be called Subband Non-overlapping Full Duplex (SBFD) time slots / symbols. Correspondingly, for time slots / symbols without subbands, they can be called non-SBFD time slots / symbols.

[0003] The frequency domain resource allocation methods used in the prior art are no longer fully applicable to SBFD. For example, when the base station schedules / the network configures a terminal to perform uplink transmission or downlink reception in multiple time slots, the time domain resources corresponding to the transmission of channels / signals such as the Physical Downlink Shared Channel (PDSCH) and the Physical Uplink Shared Channel (PUSCH) may include both SBFD time slots and non-SBFD time slots. In this case, if frequency domain resources are allocated to the PDSCH / PUSCH using the traditional method, that is, according to the available bandwidth in the non-SBFD time slot, the allocated frequency domain resources in the SBFD time slot may not match the actual available resources. For example, the frequency domain resource location of the PDSCH overlaps with the location of the UL subband, which may cause transmission failure in the SBFD time slot. Summary of the Invention

[0075] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0076] The terms "first," "second," and the like in the specification and claims of the present invention are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first" and "second" are generally of the same type, and do not limit the number of objects. For example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0077] Currently, NR supports scheduling one or N PDSCHs / PUSCHs through a downlink control information (DCI) (Format 1_1 or Format 0_1). Specifically, the Time Domain Resource Assignment (TDRA) field in the DCI can indicate one or N groups of time slot offsets k2 and start and length indicator values ​​(SLIV), where k2 represents the time slot offset between the time slot where the DCI is located and the scheduled time slot, and SLIV indicates the start symbol and symbol length of the PDSCH / PUSCH.

[0078] When the TDRA field in the DCI indicates N groups of {k2, SLIV}, N PDSCHs / PUSCHs can be scheduled simultaneously in N consecutive / non-consecutive time slots. At the same time, the frequency domain resource assignment (FDRA) field in the DCI is used to indicate the frequency domain resource location of the PDSCH / PUSCH.

[0079] NR supports two frequency domain resource allocation types, namely RA Type 0 and RA Type 1. RA Type 0 is a resource allocation mechanism based on the resource block group (RBG). Specifically, it takes the starting frequency domain position of the bandwidth part (BWP) as the starting point and divides the physical resource block (PRB) into N RBGs with RBG as the granularity. RBG RBG, and then use N RBGThe bits indicate the RBGs allocated to the terminal, also known as user equipment (UE), in the form of a bitmap. Each bit corresponds to an RBG, and a bit value of 1 indicates that the corresponding RBG is allocated to the UE.

[0080] Among them, N RBG The calculation method is: Where P is the granularity of the division, in particular, the size of the first RBG is The size of the last RBG is: but otherwise The size of the remaining RBGs is P. is the starting Common Resource Block (CRB) number of the UE's current BWP, The granularity P is determined by the rbg-Size parameter and the BWP size in the Radio Resource Control (RRC) signaling PDSCH-Config / PUSCH-Config. The rbg-Size parameter indicates Configuration 1 or Configuration 2, and the RBG size P is determined by a table lookup based on the BWP size.

[0081] Resource allocation type RA Type 1 is a resource allocation mechanism based on resource indication value (RIV), which is used to allocate a set of continuous virtual resource blocks (VRBs). The starting VRB and the number of RBs can be calculated through RIV. NR supports two types of VRB-to-actual PRB mapping: non-interleaved mapping and interleaved mapping. For non-interleaved mapping, VRBs correspond one-to-one with PRBs, so the actually allocated PRBs are also continuous. Interleaved mapping performs VRB-to-PRB interleaving in resource bundles (RB bundles), which can achieve discrete PRB allocation.

[0082] When the UE is configured or indicated with the repetition transmission parameter PDSCH aggregation factor (pdsch-AggregationFactor) or repetition number (repetitionNumber), the UE repeatedly receives an identical downlink transport block (TB) over multiple consecutive time slots, and allocates the same starting symbol and symbol length, as well as the same frequency domain resource position, in each time slot. When the UE is configured or indicated with the repetition transmission parameter pdsch-AggregationFactor or repetition numberOfRepetitions, the UE repeatedly transmits an identical uplink TB over multiple consecutive time slots, and allocates the same starting symbol and symbol length, as well as the same frequency domain resource position, in each time slot.

[0083] To enhance uplink coverage, multi-slot data transmission (TB processing over multi-slot PUSCH, TBoMS) was introduced. When the UE is indicated with the higher-layer parameter numberOfSlotsTBoMS, it can transmit a TB over multiple consecutive time slots, with each time slot using the same symbols and PRB resources. Compared to transmitting a TB in a single time slot, the increased number of available PRBs allows the use of lower coding and modulation schemes, thereby achieving enhanced uplink coverage.

[0084] When the base station schedules / the network configures the terminal to perform uplink transmission or downlink reception on multiple time slots, such as the above-mentioned PDSCH / PUSCH repeated transmission and TBoMS, the PDSCH / PUSCH transmission may span SBFD time slots / symbols and non-SBFD time slots / symbols. Figure 1 A schematic diagram of one embodiment of frequency domain subband configuration in an SBFD system, wherein in an SBFD time slot / symbol, the carrier bandwidth is divided into several subbands, including: a DL subband (DL subband) and a UL subband (UL subband), and optionally, a guard subband.

[0085] Obviously, the bandwidth available for uplink / downlink transmission in SBFD time slots / symbols and non-SBFD time slots / symbols is different, such as Figure 1As shown in the figure, assuming a 100MHz carrier bandwidth, slots #0 and #4 are non-SBFD slots, while slots #1, #2, and #3 are SBFD slots. If the network configures a 20MHz UL subband bandwidth for SBFD slots #1, #2, and #3, the DL subband bandwidth does not exceed 80MHz (taking into account the presence of the guard subband) and is divided into two discontinuous parts. For non-SBFD slot #0, the bandwidth available for downlink transmission is 100MHz.

[0086] Therefore, when the base station schedules / the network configures the terminal to perform uplink transmission or downlink reception on multiple time slots, such as repeated transmission of PDSCH / PUSCH, TBoMS PUSCH, etc., the transmission of PDSCH / PUSCH may span SBFD time slots and non-SBFD time slots. At this time, if frequency domain resources are allocated to PDSCH / PUSCH according to the existing technology, that is, frequency domain resources are allocated according to the available bandwidth on the non-SBFD time slot, the frequency domain resources allocated on the SBFD time slot may not match the actual available resources. For example, the frequency domain resource position of PDSCH overlaps with the position of the UL subband, which may cause transmission failure on the SBFD time slot.

[0087] In order to solve the above technical problems, one embodiment of the present invention provides a frequency domain resource determination method. When it is determined that the time domain resources for uplink transmission or downlink reception include SBFD symbols and non-SBFD symbols according to the time domain resource information, it is determined that on the SBFD symbol, the frequency domain resources corresponding to the uplink transmission or downlink reception of the terminal do not include the first frequency domain resources according to the frequency domain resource information, wherein the first frequency domain resources are frequency domain resources that cannot be used for uplink transmission or downlink reception, so as to avoid the situation where the frequency domain resources corresponding to the channel / signal transmission on the SBFD time slot do not match the actual available resources.

[0088] like Figure 2 As shown, one embodiment of the present invention provides a method for determining frequency domain resources, which is performed by a terminal. The method includes:

[0089] S210: The terminal receives first information sent by a network-side device, where the first information includes time domain resource information and frequency domain resource information for uplink transmission or downlink reception by the terminal;

[0090] S220, when it is determined, based on the time domain resource information, that the time domain resource for uplink transmission or downlink reception includes SBFD symbols and non-SBFD symbols, determining, based on the frequency domain resource information, that the frequency domain resource corresponding to uplink transmission or downlink reception by the terminal on the SBFD symbol does not include a first frequency domain resource, where the first frequency domain resource is configured by a network-side device;

[0091] The SBFD symbols and the non-SBFD symbols belong to different time slots.

[0092] Using the frequency domain resource determination method described in an embodiment of the present invention, if the terminal determines that the time domain resources for uplink transmission or downlink reception include SBFD symbols and non-SBFD symbols, that is, the uplink transmission or downlink reception of the terminal spans SBFD symbols and non-SBFD symbols, then it is determined that on the SBFD symbols, the frequency domain resources corresponding to the uplink transmission or downlink reception of the terminal do not include the first frequency domain resources, that is, do not include the frequency domain resources in the SBFD symbol that cannot be used for uplink transmission or downlink reception, so as to avoid the situation where the frequency domain resources corresponding to the channel / signal transmission on the SBFD time slot do not match the actual available resources.

[0093] In the embodiment of the present invention, specifically, the frequency domain resources are resources for uplink transmission by the terminal, and the first frequency domain resources include frequency domain resources corresponding to a downlink subband and a protection subband; or

[0094] The frequency domain resources are resources used by the terminal for downlink reception, and the first frequency domain resources include frequency domain resources corresponding to an uplink subband and a protection subband.

[0095] Optionally, the first information is downlink control information (Downlink Control Information, DCI).

[0096] In one embodiment of the present invention, optionally, in step S220, determining, based on the frequency domain resource information, that the frequency domain resource corresponding to uplink transmission or downlink reception by the terminal on the SBFD symbol does not include the first frequency domain resource includes:

[0097] It is determined according to the frequency domain resource information that, on the SBFD symbol, the allocated frequency domain resources corresponding to the uplink transmission or downlink reception performed by the terminal indicated by the frequency domain resource information do not include a resource block RB in the first frequency domain resources.

[0098] By adopting this implementation mode, when the network side device schedules the terminal to perform uplink transmission (such as sending PUSCH) or downlink reception (such as receiving PDSCH), it can determine whether the transmission or repeated transmission of the same transmission block TB includes SBFD symbols in the time domain. If SBFD symbols are included, the network side device ensures that the terminal is scheduled to receive PDSCH only within the frequency domain resources of DLsubband(s) or to send PUSCH only within the frequency domain resources of ULsubband when sending information for indicating the frequency domain resources for the terminal to perform uplink transmission or downlink reception, regardless of whether it is in SBFD time slot / symbol or non-SBFD time slot / symbol.

[0099] Therefore, for the terminal, the terminal does not expect that the frequency domain resources for receiving PDSCH indicated by the FDRA field in the DCI sent by the received network side device overlap with the UL subband and / or protection band, and does not expect that the frequency domain resources for sending PUSCH indicated by the FDRA field in the DCI overlap with the DL subband and / or protection band.

[0100] Based on the above, the frequency domain resource determination method described in the embodiment of the present invention, in this implementation, is implemented based on the scheduling of the network side device to ensure that the terminal determines that the allocated frequency domain resources corresponding to the terminal's uplink transmission or downlink reception do not include RBs in the first frequency domain resources based on the frequency domain resource information in the DCI sent by the network side device.

[0101] Specifically, for PDSCH transmission, if the frequency domain resource allocation type is configured or indicated as RA Type 1, the network side device ensures that the FDRA field (frequency domain resource information) indicates the secondary RB when sending DCI. start Start continuous L RBs RBs are all within the frequency range of the DL subband(s); if the frequency domain resource allocation type is configured or indicated as RA Type 0, the base station ensures that the value of the bitmap in the FDRA field (frequency domain resource information) meets the conditions when sending DCI: only the bit value corresponding to the RBG that does not overlap with the UL subband and guardband(s) can be 1;

[0102] For PUSCH transmission, if the frequency domain resource allocation type is configured or indicated as RA Type 1, the base station ensures that the FDRA field (frequency domain resource information) indicates the secondary RB when sending DCI. start Start continuous L RBsAll RBs are within the frequency range of the UL subband; if the frequency domain resource allocation type is configured or indicated as RAType 0, the base station ensures that the value of the bitmap in the FDRA domain (frequency domain resource information) meets the conditions when sending DCI: only the bit value corresponding to the RBG that does not overlap with the DL subband(s) and guard band(s) can be 1.

[0103] In an embodiment of the present invention, another implementation method, optionally, when it is determined that the time domain resources for uplink transmission or downlink reception include SBFD symbols, based on the terminal implementation, when the terminal determines the frequency domain resources corresponding to uplink transmission or downlink reception on the SBFD symbols, it ensures that the determined frequency domain resources do not include the first frequency domain resources.

[0104] In this implementation manner, optionally, in step 220, when it is determined based on the frequency domain resource information that, on the SBFD symbol, the allocated frequency domain resources corresponding to the uplink transmission or downlink reception of the terminal indicated by the frequency domain resource information include at least one RB in the first frequency domain resources, after performing one or more of the following operations, the frequency domain resources corresponding to the uplink transmission or downlink reception of the terminal are determined, so that the determined frequency domain resources do not include the first frequency domain resources:

[0105] Replacing the RB included in the first frequency domain resource in the allocated frequency domain resources with a second frequency domain resource; wherein the second frequency domain resource is a frequency domain resource located outside the allocated frequency domain resources and does not belong to the first frequency domain resource and can be used by the terminal for uplink transmission or downlink reception;

[0106] Rate matching or puncturing is performed on the RBs in the allocated frequency domain resources included in the first frequency domain resources.

[0107] With this implementation, when the terminal determines, based on the frequency domain resource information, that the allocated frequency domain resources on the SBFD time slot / symbol do not match the actual available resources, for example, the frequency domain resource position of the PDSCH overlaps with the UL subband and / or guard band guardband(s), or the frequency domain resource position of the PUSCH overlaps with the DL subband(s) and / or guard band(s), or in other words, the determined allocated frequency domain resources of the PDSCH include at least one RB in the UL subband or guard band guard band(s) (first frequency domain resources), or the determined allocated frequency domain resources of the PUSCH include at least one RB in the DL subband(s) or guard band(s). In the case of at least one RB in band(s) (first frequency domain resources), the RBs included in the first frequency domain resources in the allocated frequency domain resources are replaced with second frequency domain resources that are outside the allocated frequency domain resources and do not belong to the first frequency domain resources and can be used for PDSCH reception or PUSCH transmission, or the RBs included in the first frequency domain resources are rate matched or punctured to ensure that when the terminal determines the frequency domain resources corresponding to uplink transmission or downlink reception on the SBFD symbol, the determined frequency domain resources do not include the first frequency domain resources.

[0108] In this embodiment of the present invention, optionally, when at least one of the following conditions is satisfied, it is determined that, on the SBFD symbol, the allocated frequency domain resources indicated by the frequency domain resource information include at least one RB in the first frequency domain resources:

[0109] On the SBFD symbol, at least one RB in at least one RBG in the allocated frequency domain resources determined according to the bitmap value indicated by the frequency domain resource information is included in the first frequency domain resources, wherein the bitmap value corresponding to the RBG in the allocated frequency domain resources is a first preset value;

[0110] On the SBFD symbol, N RBs in the allocated frequency domain resources determined according to a resource indication value (RIV) indicated by the frequency domain resource information are included in the first frequency domain resources; N is an integer greater than or equal to 1.

[0111] Specifically, when the network side device schedules the terminal to receive PDSCH or send PUSCH, if the transmission or repeated transmission of the same TB includes both SBFD time slots / symbols and non-SBFD time slots / symbols in the time domain, and the frequency domain resource allocation type is configured or indicated as resourceAllocationType0 (RA Type 0), on the SBFD time slot / symbol, the terminal determines the allocated frequency domain resource position on the SBFD time slot / symbol according to the bitmap indicated by the FDRA field in the DCI. If there is at least one RBG, the bitmap value indicated by the FDRA field is 1 (first preset value), and at least one RB in the RBG is included in the first frequency domain resources, then it is determined that on the SBFD symbol, the allocated frequency domain resources indicated by the frequency domain resource information include at least one RB in the first frequency domain resources.

[0112] When the network side device schedules the terminal to receive PDSCH or send PUSCH, if the transmission or repeated transmission of the same TB includes both SBFD time slots / symbols and non-SBFD time slots / symbols in the time domain, and the frequency domain resource allocation type is configured or indicated as resourceAllocationType1 (RA Type 1), on the SBFD time slot / symbol, the terminal determines the allocated frequency domain resource position on the SBFD time slot / symbol according to the RIV value indicated by the FDRA field in the DCI. If N RBs in the determined allocated frequency domain resources are included in the first frequency domain resources, and N is an integer greater than or equal to 1, it is determined that on the SBFD symbol, the allocated frequency domain resources indicated by the frequency domain resource information include at least one RB in the first frequency domain resources.

[0113] In one embodiment, when the network side device schedules the terminal to receive PDSCH or send PUSCH, if the transmission or repeated transmission of the same TB includes both SBFD time slots / symbols and non-SBFD time slots / symbols in the time domain, and the frequency domain resource allocation type is configured or indicated as resourceAllocationType0 (RAType 0), the RBG size and the size of the FDRA field in the DCI are still determined based on the DL BWP or UL BWP. The terminal determines the frequency domain resource location for receiving PDSCH or sending PUSCH according to the bitmap indicated by the FDRA field in the DCI as follows:

[0114] In non-SBFD time slots / symbols, the terminal directly determines the frequency domain resource location for receiving PDSCH or sending PUSCH based on the FDRA field in the DCI; specifically, the BWP is divided into N RBG RBG, accordingly, the FDRA field contains a length of N RBGThe bitmap is a bit sequence consisting of 0s and 1s, where each bit corresponds to an RBG in the BWP. A bit value of 1 indicates that the corresponding RBG is allocated to the terminal for PDSCH reception or PUSCH transmission, otherwise it indicates that it is not allocated to the terminal. The terminal can determine the location of all frequency domain resources used for PDSCH reception or PUSCH transmission by reading the bitmap value in FDRA;

[0115] In the SBFD time slot / symbol, the terminal first determines the frequency domain resource position for receiving PDSCH or sending PUSCH according to the FDRA field in the DCI, and obtains the frequency domain resource position scheduled by the network side device, that is, determines the allocated frequency domain resources according to the frequency domain resource information. When it is determined that the corresponding allocated frequency domain resources include at least one RB in the first frequency domain resources, the RB included in the first frequency domain resources is replaced with the second frequency domain resources, or the RB included in the first frequency domain resources in the allocated frequency domain resources is rate matched or punctured.

[0116] Specifically, if the determined frequency domain resource position scheduled by the network side device overlaps with the resource position of the first frequency domain resource, if there is at least one RBG, its corresponding bitmap value is 1, and it completely overlaps with the resource position of the first frequency domain resource or only part of the RB(s) overlaps with the resource position of the first frequency domain resource, then optionally, the following operations may be performed:

[0117] In the resources that overlap with the resource position of the first frequency domain resource, for the RBG that completely overlaps with the resource position of the first frequency domain resource, its corresponding bitmap value is reset to 0. At the same time, an RBG (second frequency domain resource) with a corresponding bitmap value of 0 is found inside the BWP and outside the first frequency domain resource, and the corresponding bitmap value is replaced with 1; for the RBG that partially overlaps with the resource position of the first frequency domain resource, its corresponding bitmap value is still kept as 1, and the RB(s) of the overlapping part is recorded as the third frequency domain resource. The terminal determines the frequency domain resource position for PDSCH reception or PUSCH transmission according to the replaced bitmap, and performs rate matching or puncturing operations on the third frequency domain resource.

[0118] In another embodiment, optionally, if the determined frequency domain resource location scheduled by the network side device overlaps with the resource location of the first frequency domain resource, if there is at least one RBG, its corresponding bitmap value is 1, and it completely overlaps with the resource location of the first frequency domain resource or only part of the RB(s) overlaps with the resource location of the first frequency domain resource, then optionally, the following operations may also be performed:

[0119] In the resources overlapping with the resource position of the first frequency domain resources, for the RBG that at least partially overlaps with the resource position of the first frequency domain resources, the corresponding bitmap value is reset to 0. At the same time, at least one RBG (second frequency domain resource) with a corresponding bitmap value of 0 is found inside the BWP and outside the resource position of the first frequency domain resources, and the bitmap value is replaced with 1; the terminal determines the frequency domain resource position for PDSCH reception or PUSCH transmission based on the replaced bitmap value.

[0120] According to the above, in an embodiment of the present invention, optionally, replacing the RB included in the first frequency domain resource in the allocated frequency domain resource with the second frequency domain resource includes:

[0121] For at least one RB in the allocated frequency domain resources that is included in a resource block group RBG in the first frequency domain resources, the corresponding RBG is replaced with the second frequency domain resources.

[0122] Optionally, performing rate matching or puncturing on the RBs in the allocated frequency domain resources included in the first frequency domain resources includes:

[0123] For an RBG in which at least one RB in the allocated frequency domain resources includes the first frequency domain resources, rate matching or puncturing is performed on a corresponding RB in the RBG included in the first frequency domain resources.

[0124] Optionally, when the bitmap value of the resource block group RBG is a first preset value (such as 1), replacing the corresponding RBG with the second frequency domain resource includes:

[0125] Setting the bitmap value of the RBG to a second preset value (such as 0), and determining at least one RBG that does not belong to the first frequency domain resource and whose corresponding bitmap value is the second preset value as the second frequency domain resource;

[0126] The bitmap value corresponding to the RBG in the second frequency domain resource is set to a first preset value.

[0127] In the above implementation of the embodiment of the present invention, the first frequency domain resources refer to the frequency domain resources corresponding to the subband(s) and guard band(s) that cannot be used for transmission. For downlink reception, the first frequency domain resources include UL subband and guard band. For uplink transmission, the first frequency domain resources include DL subband(s) and guard band.

[0128] In another embodiment, when the network side device schedules the terminal to receive PDSCH or send PUSCH, if the transmission or repeated transmission of the same TB includes both SBFD time slots / symbols and non-SBFD time slots / symbols in the time domain, and the frequency domain resource allocation type is configured or indicated as resourceAllocationType1 (RA Type1), the terminal determines the frequency domain resource location for receiving PDSCH or sending PUSCH according to the RIV indicated by the FDRA field in the DCI as follows:

[0129] In the non-SBFD time slot / symbol, the terminal directly determines the frequency domain resource location of PDSCH or PUSCH according to the FDRA field in the DCI; specifically, according to the RIV in the FDRA field, the network side device calculates the starting RB (expressed as RB) of the allocated frequency domain resource corresponding to the terminal's uplink transmission or downlink reception indicated by the frequency domain resource information. start ) and RB length (expressed as L RBs ), among which, RB start Indicates the starting RB position of the allocated frequency domain resources in the BWP, L RBs Indicates the number of consecutive RBs of the allocated frequency domain resources allocated to the terminal. The terminal start and L RBs The resource location of the allocated frequency domain resources for PDSCH reception or PUSCH transmission can be determined;

[0130] In the SBFD time slot / symbol, the terminal determines the allocated frequency domain resources corresponding to the uplink transmission or downlink reception of the terminal indicated by the network side device through the frequency domain resource information according to the RIV indicated by the FDRA field in the DCI, and obtains the starting RB (such as RB start ) and RB length (expressed as L RBs ); If the allocated frequency domain resources overlap with the first frequency domain resources, such as N RBs in the allocated frequency domain resources are included in the first frequency domain resources, the method for determining the frequency domain resource position for receiving PDSCH or sending PUSCH is as follows:

[0131] Keep RB start No change, let L RBs =L RBs +N, that is, in addition to the allocated frequency domain resources determined according to the frequency domain resource information indicated by the FDRA field, N RBs are added to the UE in the direction of increasing frequency. If L RBs The frequency domain resource position after +N does not exceed the boundary of BWP, then the frequency domain resource position for the terminal to receive PDSCH or send PUSCH is from RB start Start, to L RBs+N ends, and the N RBs overlapping with the first frequency domain resources are removed; in this implementation, the N RBs (second frequency domain resources) after the allocated frequency domain resources determined according to the FDRA domain replace the N RBs included in the first frequency domain resources in the allocated frequency domain resources.

[0132] If N RBs are added to the UE in the direction of increasing frequency according to the above method, L RBs The frequency domain resource position of +N exceeds the boundary of BWP. Set the number of RBs that exceed to N1, then set RB start =RB start -N1, at this time, the frequency domain resource location for the terminal to receive PDSCH or send PUSCH is from RB start -Starting from N1, to L RBs The N RBs that overlap with the first frequency domain resources are removed. The difference between N and N1 is N2. In this embodiment, the N2 RBs after the allocated frequency domain resources and the N1 RBs before the allocated frequency domain resources (second frequency domain resources) determined according to the FDRA field replace the N RBs included in the first frequency domain resources in the allocated frequency domain resources.

[0133] Therefore, according to the above, on the SBFD symbol, when the N RBs in the allocated frequency domain resources determined according to the resource indication value RIV indicated by the frequency domain resource information are included in the first frequency domain resources, determining the second frequency domain resources includes one of the following:

[0134] N RBs located after the allocated frequency domain resources in a frequency increasing direction;

[0135] Along the frequency increasing direction, N1 RBs located before the allocated frequency domain resources and N2 RBs located after the allocated frequency domain resources; wherein the sum of N1 and N2 is equal to N.

[0136] The frequency domain resource determination method described in an embodiment of the present invention adopts the above-mentioned implementation method. When the frequency domain resource allocation type is configured or indicated as RA Type 0 or RA Type 1, when determining that the time domain resources for uplink transmission or downlink reception include SBFD symbols, according to the frequency domain resource information sent by the network side device, when determining that on the SBFD symbol, the allocated frequency domain resources corresponding to the terminal performing uplink transmission or downlink reception include at least one RB in the first frequency domain resources, by replacing the RB included in the first frequency domain resources in the allocated frequency domain resources with the second frequency domain resources, or, performing rate matching or punching processing on the RB included in the first frequency domain resources in the allocated frequency domain resources, so that the frequency domain resources corresponding to the uplink transmission or downlink reception of the terminal finally determined do not include the first frequency domain resources, so as to avoid the situation where the frequency domain resources corresponding to the channel / signal transmission on the SBFD time slot do not match the actual available resources.

[0137] In one embodiment of the present invention, optionally, the method further includes:

[0138] Obtain second information sent by a network side device; wherein the second information is a first value, used to indicate that on the SBFD symbol, when the allocated frequency domain resources corresponding to the uplink transmission or downlink reception of the terminal indicated by the frequency domain resource information include at least one RB in the first frequency domain resources, the RB included in the first frequency domain resources in the allocated frequency domain resources is replaced with the second frequency domain resources;

[0139] The second information is a second value, which is used to indicate that on the SBFD symbol, when the allocated frequency domain resources corresponding to the uplink transmission or downlink reception of the terminal indicated by the frequency domain resource information include at least one RB in the first frequency domain resources, rate matching or puncturing is performed on the RBs in the allocated frequency domain resources included in the first frequency domain resources.

[0140] Using this implementation mode, the terminal is configured through the second information sent by the network side device, so that when the terminal determines that the allocated frequency domain resources corresponding to uplink transmission or downlink reception include at least one RB in the first frequency domain resources, it determines whether to replace the RB included in the first frequency domain resources in the allocated frequency domain resources with the second frequency domain resources, or to perform rate matching or puncturing on the RB included in the first frequency domain resources.

[0141] Optionally, the first value and the second value may be preset field information respectively, such as but not limited to only TRUE and FALSE values.

[0142] The frequency domain resource determination method according to the embodiment of the present invention is described below with examples in conjunction with specific implementation methods.

[0143] Implementation Method 1

[0144] Combine Figure 3 As shown, in this implementation, the base station sends DCI and schedules the terminal to receive PDSCH in time slot #0, and the network side device configures the high-level parameter as pdsch-AggregationFactor = 2. In this case, the terminal receives repeated transmission of PDSCH in time slot #1. According to the traditional frequency domain resource allocation method, the time domain symbol position and frequency domain resource position used in the two transmissions in time slot #0 and time slot #1 are the same, but the UL subband and guard bands (first frequency domain resources) in time slot #1 cannot be used for PDSCH reception, so there is a resource mismatch.

[0145] Using the method described in an embodiment of the present invention, in the embodiment of the present invention, when it is determined that time slot #0 for repeated transmission is a non-SBFD time slot, and time slot #1 is an SBFD time slot, and it is determined that the UL subband and guard bands (first frequency domain resources) in time slot #1 cannot be used for PDSCH reception, the UL subband and guard bands in time slot #1 are replaced with second frequency domain resources, so that the replaced second frequency domain resources can be used for PDSCH reception.

[0146] Optionally, in this embodiment, the frequency domain resource allocation type is configured as RA Type 1, then the terminal determines the starting RB and RB length for allocating frequency domain resources based on the RIV indicated by the FDRA field in the DCI in time slot #0, and determines the frequency domain resources for the terminal to receive PDSCH based on the determined starting RB, RB length, and the number of RBs included in the UL subband and guardbands in time slot #1.

[0147] Combine Figure 3 As shown, in this embodiment, according to the RIV indicated by the FDRA field in the DCI, it is determined that the N RBs in the allocated frequency domain resources are included in the UL subband and guard bands, then the starting RB of the allocated frequency domain resources remains unchanged, and in the L RBs Then, N RBs are added in the direction of increasing frequency and determined as second frequency domain resources, which replace the N RBs included in the UL subband and guard bands and are determined as frequency domain resources for the terminal to receive the PDSCH.

[0148] Implementation Method 2

[0149] Combine Figure 4As shown, in this implementation, the base station sends DCI and schedules the terminal to receive PDSCH in time slot #0, and the network side device configures the high-level parameter as pdsch-AggregationFactor = 2. In this case, the terminal receives repeated transmission of PDSCH in time slot #1. According to the traditional frequency domain resource allocation method, the time domain symbol position and frequency domain resource position used in the two transmissions in time slot #0 and time slot #1 are the same, but the UL subband and guard bands (first frequency domain resources) in time slot #1 cannot be used for PDSCH reception, so there is a resource mismatch.

[0150] Using the method described in an embodiment of the present invention, in the embodiment of the present invention, when it is determined that time slot #0 for repeated transmission is a non-SBFD time slot, and time slot #1 is an SBFD time slot, and it is determined that the UL subband and guard bands (first frequency domain resources) in time slot #1 cannot be used for PDSCH reception, the UL subband and guard bands in time slot #1 are replaced with second frequency domain resources, so that the replaced second frequency domain resources can be used for PDSCH reception.

[0151] Different from the first embodiment, in the second embodiment, the frequency domain resource allocation type is configured as RA Type 0, then the terminal determines all RBGs of the allocated frequency domain resources indicated by the FDRA field for the terminal to receive PDSCH according to the bitmap indicated by the FDRA field in the DCI on time slot #0, and on time slot #1 according to the overlap of the UL subband and guard bands with the RBGs in the allocated frequency domain resources, combined with Figure 4 As shown, for the RBG in the allocated frequency domain resources that at least partially overlaps with the UL subband and guardbands in time slot #1, the corresponding bitmap value is reset to 0. At the same time, at least one RBG (second frequency domain resource) with a corresponding bitmap value of 0 is found inside the BWP and outside the resource position of the first frequency domain resource, the bitmap value is replaced with 1, and the frequency domain resource position for PDSCH reception is determined according to the replaced bitmap value.

[0152] It should be noted that, in the embodiment of the present invention, when an RBG in the allocated frequency domain resources overlaps with only some RBs of the subband and guard band in time slot UL#1, the corresponding bitmap value is also reset to 0.

[0153] Implementation Method 3

[0154] In the third embodiment, combined with Figure 4 and Figure 5As shown, the resource position of the allocated frequency domain resources for scheduling the terminal to receive PDSCH in time slot #0 is the same as that in the second embodiment, in which the base station sends DCI and schedules the terminal to receive PDSCH in time slot #0, and the frequency domain resource allocation type is also configured as RA Type 0. In this embodiment, unlike the second embodiment, for the allocated frequency domain resources, when all RBs in one RBG overlap with the UL subband and guard bands in time slot #1, the bitmap value corresponding to the RBG is reset to 0, and at the same time, at least one RBG (second frequency domain resource) with a corresponding bitmap value of 0 is found inside the BWP and outside the resource position of the first frequency domain resource; for the allocated frequency domain resources, when part of the RBs in an RBG overlap with the UL subband and guard bands in time slot #1, the bitmap value corresponding to the RBG remains 1, and the frequency domain resource position for PDSCH reception is determined according to the replaced bitmap, and a rate matching operation is performed on the part of the RBs in the RBG that overlap with the UL subband and guard band, as shown in FIG. Figure 5 shown.

[0155] Implementation Method 4

[0156] like Figure 6 As shown, in this implementation, the base station sends DCI and schedules the terminal to send PUSCH in time slot #0, and the network-side device configures the high-level parameter as pdsch-AggregationFactor=2. When time slot #0 is a UL time slot, time slot #1 is a DL time slot, and time slot #2 is an SBFD time slot, the terminal repeatedly transmits the same PUSCH in time slot #0 and time slot #2, and the symbol positions in the two time slots are the same. In this implementation, based on the scheduling implementation of the network-side device, when scheduling the terminal to send PUSCH, the network-side device can determine that the terminal transmits the same PUSCH in time slot #0 and time slot #2, and time slot #2 includes SBFD symbols. Therefore, during scheduling, it is ensured that the frequency domain resource position indicated by the DCI is included in the frequency domain range of the UL subband of time slot #2, that is, the terminal does not expect the frequency domain resource position indicated by the DCI to overlap with the DL subbands and / or guard band of time slot #2.

[0157] By adopting the frequency domain resource determination method described in an embodiment of the present invention, when it is determined that the time domain resources for uplink transmission or downlink reception include SBFD symbols, the terminal determines the frequency domain resources at the available unallocated frequency domain resource position to replace the frequency domain resources of the overlapping part, or performs rate matching or puncturing operations on the frequency domain resources of the overlapping part, or, through scheduling of the network side device, ensures that the terminal is scheduled to receive PDSCH only within the frequency domain resources of the DL subband(s) or is scheduled to send PUSCH only within the frequency domain resources of the UL subband, so as to avoid the situation where the frequency domain resources corresponding to the channel / signal transmission in the SBFD time slot do not match the actual available resources.

[0158] One embodiment of the present invention further provides a method for determining frequency domain resources, which is executed by a network side device, such as Figure 7 As shown, the method includes:

[0159] S710: Send first information to a terminal, where the first information includes time domain resource information and frequency domain resource information for uplink transmission or downlink reception by the terminal;

[0160] Wherein, when the time domain resource for uplink transmission or downlink reception corresponding to the time domain resource information indicated by the first information includes SBFD symbols and non-SBFD symbols, on the SBFD symbols, the allocated frequency domain resources corresponding to the uplink transmission or downlink reception performed by the terminal indicated by the frequency domain resource information do not include resource blocks RBs in the first frequency domain resources;

[0161] The first frequency domain resource is configured by a network-side device; and the SBFD symbols and non-SBFD symbols belong to different time slots.

[0162] By adopting the frequency domain resource determination method described in this embodiment, through the scheduling of the network side device, it is ensured that the terminal is scheduled to receive PDSCH only within the frequency domain resources of DL subband(s) or the terminal is scheduled to send PUSCH only within the frequency domain resources of UL subband, so as to avoid the situation where the frequency domain resources corresponding to the channel / signal transmission in the SBFD time slot do not match the actual available resources.

[0163] Optionally, in the frequency domain resource determination method, the frequency domain resource is a resource for uplink transmission by the terminal, and the first frequency domain resource includes a frequency domain resource corresponding to a downlink subband and / or a protection subband; or

[0164] The frequency domain resources are resources used by the terminal for downlink reception, and the first frequency domain resources include frequency domain resources corresponding to an uplink subband and / or a protection subband.

[0165] Optionally, the method for determining frequency domain resources further includes:

[0166] Sending second information to the terminal; wherein the second information is a first value, used to indicate that on the SBFD symbol, when the allocated frequency domain resources corresponding to the uplink transmission or downlink reception of the terminal indicated by the frequency domain resource information include at least one RB in the first frequency domain resources, the RB included in the first frequency domain resources in the allocated frequency domain resources is replaced with the second frequency domain resources;

[0167] The second information is a second value, which is used to indicate that on the SBFD symbol, when the allocated frequency domain resources corresponding to the uplink transmission or downlink reception of the terminal indicated by the frequency domain resource information include at least one RB in the first frequency domain resources, rate matching or puncturing is performed on the RBs in the allocated frequency domain resources included in the first frequency domain resources.

[0168] For the specific implementation of the frequency domain resource determination method described in the embodiment of the present invention applied to the network side device, please refer to the detailed description of the specific implementation of the method when applied to the terminal, and will not be repeated here.
