Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method, device, terminal and network equipment for determining frequency hopping information. Background Art

[0002] In order to solve the coverage, delay and capacity problems of uplink transmission in the time division duplex (TDD) mode, the direction of non-overlapping sub-band full duplex (SBFD) will be studied. That is, the frequency domain resources are divided into multiple sub-bands that do not overlap with each other. The uplink and downlink frequency domain resources are located in different sub-bands, which is referred to as sub-band full-duplex.

For the uplink symbol of the TDD mode, if the uplink symbol is not configured with a downlink sub-band, it can also be called a full uplink symbol.

[0165] The frequency hopping related information sent by the network device may include indication information of whether frequency hopping is enabled and / or frequency offset information of frequency hopping. The terminal determines whether frequency hopping is enabled on the SBFD symbol and / or the frequency offset of the frequency hopping on the SBFD symbol, and the terminal determines whether frequency hopping is enabled on the uplink symbol and / or the frequency offset information of the frequency hopping on the uplink symbol.

The frequency hopping related information can be used to indicate whether frequency hopping is enabled, for example: the frequency hopping related information sent by the network device includes 1, indicating that frequency hopping is enabled; the frequency hopping related information sent by the network device includes 0, indicating that frequency hopping is not enabled. The opposite is also possible, and the specific indication method is not limited here.

[0167] It should be noted that the SBFD symbol in the embodiment of the present application can also be replaced by an SBFD time slot, wherein the SBFD time slot is a time slot in which all or part of the symbols are SBFD symbols, and the uplink symbol can also be replaced by an uplink time slot, that is, the terminal determines whether to enable frequency hopping and / or the frequency offset of frequency hopping on the SBFD time slot according to the frequency hopping related information indicated by the network device, and determines whether to enable frequency hopping and / or the frequency offset of frequency hopping on the uplink time slot.

[0181] This embodiment is an embodiment of determining whether to enable frequency hopping on the SBFD symbol based on the frequency domain resource configuration information or allocation information on the SBFD symbol. If the number of RBs corresponding to the frequency domain resources allocated or configured on the SBFD symbol is greater than (or greater than or equal to) the first value K1, frequency hopping on the SBFD symbol is not enabled; otherwise, frequency hopping on the SBFD symbol is enabled. The first value may be a predefined parameter, for example: the first value is the number of RBs contained in the uplink subband / 2, or the first value is a parameter configured by the network device.

The second value can be a predefined parameter, for example: the second value is the number of RBs included in the uplink subband / 2, or the second value is a parameter configured by the network device.

[0187] It should be noted that the greater than or equal to described in the embodiment of the present application may include “>” and may also include “≥”, and the less than or equal to described in the embodiment of the present application may include “<” and may also include “≤”.

Specifically, the starting RB position of each hop can be calculated according to the first starting RB position indicated by the frequency domain resource allocation information or the frequency domain resource configuration information on the SBFD symbol, and then the frequency offset between the starting RBs of the two hops can be determined.

[0195] As an optional embodiment, the terminal determines whether to enable frequency hopping on the SBFD symbol according to the frequency hopping related information, including:

[0196] If the frequency hopping related information does not include the frequency offset of the physical uplink shared channel PUSCH frequency hopping dedicated to the SBFD symbol, frequency hopping is not enabled on the SBFD symbol.

[0197] In this embodiment, the UE determines whether to perform PUSCH frequency hopping on the SBFD symbol according to whether the base station is configured with a frequency offset for PUSCH frequency hopping on the SBFD symbol. If the base station is configured with a frequency offset for PUSCH frequency hopping on the SBFD symbol, the UE performs PUSCH frequency hopping on the SBFD symbol; if the base station is not configured with a frequency offset for PUSCH frequency hopping on the SBFD symbol, the UE does not perform PUSCH frequency hopping on the SBFD symbol.

[0198] Optionally, the method for the terminal to determine whether to enable frequency hopping on a SBFD symbol may be applied to a variety of transmissions, such as at least one of the following:

[0199] Type 1 configured grant PUSCH transmission;

[0200] Type 2 configured grant PUSCH transmission;

[0201] PUSCH transmission scheduled by downlink control information (DCI);

[0202] DCI activates PUSCH transmission of Semi-Persistent Channel State Information (SP-CSI).

[0203] Optionally, determining the starting RB position of each of the two hops according to the first starting RB position indicated by the frequency domain resource allocation information or configuration information on the SBFD symbol and the frequency offset indicated by the frequency offset information of the frequency hopping includes:

[0204] Determine the starting RB position of each hop in the two hops according to the first starting RB position indicated by the frequency domain resource allocation information or configuration information on the SBFD symbol, the frequency offset indicated by the frequency offset information of the frequency hopping, and the second information;

[0205] The second information includes at least one of the following:

[0206] The number of RBs included in the BWP;

[0207] The number of RBs contained in the uplink subband;

[0208] The timeslot number where the multi-slot transmission is located;

[0209] The number of the SBFD symbol within the time slot range where the multi-slot transmission is located;

[0210] The number of the uplink symbol within the time slot range where the multi-slot transmission is located;

[0211] The number of repetitions;

[0212] The relative number of the time slots in which the multi-slot transmission occurs;

[0213] Number of the SBFD configuration period;

[0214] The number of the time division duplex (TDD) configuration period.

[0215] In this embodiment, the starting RB position of each hop in the two hops can be calculated by the following formula 1 or formula 2:

[0216] Formula 1:

[0217]

[0218] in, It is calculated The starting RB in the time slot, Indicates the current time slot number, which is the time slot number where the multi-slot transmission is located; RB start The starting RB in the uplink BWP, RB offset is the frequency offset value between two hops (in PRB units); Indicates the size of the uplink BWP (that is, the number of RBs contained in the BWP). start and RB offset It is the value indicated in the frequency domain resource allocation information or configuration information on the SBFD symbol, and can be determined by the frequency domain resource allocation field in the resource allocation type 1.

[0219] Formula 2:

[0220]

[0221] in, Indicates the size of the uplink subband (the number of RBs contained in the uplink subband).

[0222] The starting RB position of each hop can be calculated by the above formula 1 or formula 2. For formula 1 and formula 2, the frequency domain resource allocation (including the starting RB and the number of RBs) on different symbol types can share the same frequency domain resource indication information / frequency domain resource configuration information, or can be configured or indicated separately, or determined separately.

[0223] Methods for separately determining frequency domain resource allocation on different symbol types include, for example, sharing a frequency domain resource indication information, and determining the starting RB position on the full uplink and SBFD symbols according to different interpretation rules. For example, the reference point of the starting position on the full uplink symbol is the starting RB of the uplink BWP, while the reference point of the starting position of the SBFD symbol is the starting RB of the UL subband.

[0224] Optionally, in order to solve the problem that when a SBFD configuration period contains only one SBFD time slot and / or a TDD configuration period contains only one full uplink time slot, the actual determined RB start Only one value, that is, frequency hopping cannot be achieved. To solve this problem, we can consider changing n in the above formula 1 and formula 2 sμ is replaced by a relative number (index) within a different time slot type, such as,

[0225] 1) Index is the timeslot number where the multi-slot transmission is located;

[0226] 2) Index is the number of the SBFD symbol within the time slot range where the multi-slot transmission is located;

[0227] 3) Index is the number of the uplink symbol within the time slot range where the multi-slot transmission is located;

[0228] 4) Index is the number of repeated transmissions;

[0229] 5) Index is the relative number of the time slot where the multi-slot transmission is located, and the index starts from 0;

[0230] 6) Index is the number of the SBFD configuration period;

[0231] 7) Index is the number of the time division duplex TDD configuration period.

[0232] The following example illustrates the implementation process of the terminal determining the frequency hopping indication on the SBFD symbol and the frequency hopping indication on the uplink symbol according to the frequency hopping related information indicated by the network device.

[0233] The network device sends frequency hopping indication information to the UE through Radio Resource Control (RRC) signaling, downlink control information (DCI) or random access response (RAR), and the UE receives the frequency hopping indication information sent by the network device. If the frequency hopping indication information sent by the network device does not enable frequency hopping, frequency hopping is not enabled on all uplink symbols (or called uplink symbols) and SBFD symbols; if the frequency hopping indication information sent by the network device enables frequency hopping, frequency hopping is enabled on all uplink symbols; whether frequency hopping is enabled on SBFD symbols can be determined based on one or more of the following information:

[0234] a: Frequency domain resource allocation information / configuration information on SBFD symbols, which may include the starting RB and / or the number of RBs;

[0235] b: uplink subband information, which may include the starting RB of the uplink subband and / or the number of RBs occupied by the uplink subband;

[0236] c: Frequency offset of frequency hopping.

[0237] The above information may be sent by the network device to the UE via RRC, System Information Block 1 (SIB1) and / or DCI.

[0238] Specifically, any of the following methods may be used to determine whether frequency hopping is enabled on the SBFD symbol:

[0239] Mode 1: If the number of RBs corresponding to the frequency domain resources allocated on the SBFD symbol is greater than (or ≥) the threshold value K1, frequency hopping on the SBFD symbol is not enabled; otherwise, frequency hopping on the SBFD symbol is enabled.

[0240] For example: K1 is the number of RBs corresponding to the uplink subband / 2. When the number of RBs corresponding to the frequency domain resource allocation on the SBFD symbol is greater than (or ≥) the number of RBs corresponding to the uplink subband / 2, frequency hopping on the SBFD symbol is not enabled; otherwise, frequency hopping on the SBFD symbol is enabled.

[0241] Mode 2: If the frequency domain position determined according to the starting RB calculation formula 1 or formula 2 is within the UL sub-band range, frequency hopping on the SBFD symbol is enabled, otherwise frequency hopping on the SBFD symbol is not enabled.

[0242] For example: the UE determines that the frequency domain position of each hop is within the uplink subband range based on the starting RB position indicated by the resource allocation information and the starting RB position of each hop determined by formula 1 or formula 2, as well as the length of the RB indicated by the resource allocation information. In this case, frequency hopping on the SBFD symbol is enabled. Otherwise, frequency hopping on the SBFD symbol is not enabled.

[0243] Mode 3: If the actual frequency offset between two starting RBs determined by starting RB calculation formula 1 or formula 2 is greater than the threshold value K2, frequency hopping on the SBFD symbol is enabled; otherwise, frequency hopping on the SBFD symbol is not enabled.

[0244] For example: the threshold K2 is the number of RBs corresponding to the uplink subband / 2. The UE determines the starting RB positions of the two hops according to the starting RB position indicated by the resource allocation information and formula 1 or formula 2. If the actual frequency offset between the starting RBs of the two hops is greater than the number of RBs corresponding to the uplink subband / 2, frequency hopping on the SBFD symbol is enabled; otherwise, frequency hopping on the SBFD symbol is not enabled.

[0245] Mode 4: If the conditions in the above-mentioned modes 2 and 3 are met at the same time, frequency hopping on SBFD symbols is enabled; otherwise, frequency hopping on SBFD symbols is not enabled.

[0246] In this embodiment, the terminal can determine the frequency hopping parameters of two types of symbols or time slots based on a set of frequency hopping indication information configured by the network device, which will not increase the signaling overhead, can reduce the implementation complexity of the network device, and increase the flexibility of the frequency hopping configuration and the frequency hopping gain.

[0247] As an optional embodiment, the terminal determines the frequency offset of the frequency hopping on the SBFD symbol and determines the frequency offset of the frequency hopping on the uplink symbol according to the frequency hopping related information, including at least one of the following:

[0248] Determine that the frequency offset on the uplink symbol is the frequency offset of the frequency hopping indicated in the frequency hopping related information, and determine the frequency offset on the SBFD symbol according to a first rule;

[0249] The frequency offset on the SBFD symbol is determined to be the frequency offset of the frequency hopping indicated in the frequency hopping related information, and the frequency offset on the uplink symbol is determined according to a second rule.

[0250] In this embodiment, the terminal can determine the frequency offset on the SBFD symbol and the frequency offset on the uplink symbol according to the frequency hopping related information sent by the network device. If the frequency offset indicated by the network device is applied to the uplink symbol, the frequency offset on the SBFD symbol is determined based on the first rule. If the frequency offset indicated by the network device is applied to the SBFD symbol, the frequency offset on the uplink symbol is determined based on the second rule.

[0251] Optionally, the first rule includes at least one of the following:

[0253] Optionally, determining a frequency offset on a SBFD symbol according to a frequency offset of the frequency hopping, an uplink BWP bandwidth, and an uplink subband bandwidth indicated in the frequency hopping related information;

[0254] The frequency offset on the SBFD symbol is determined by the following formula:

[0255]

[0256] or

[0257] Wherein, M is the frequency offset of the frequency hopping indicated in the frequency hopping related information. The unit of the frequency offset M, the uplink BWP bandwidth and the uplink subband bandwidth is RB, and the uplink BWP is the uplink BWP where the frequency hopping transmission is located or the currently activated ULBWP. Wherein, the uplink BWP bandwidth indicates the number of RBs occupied by the uplink BWP, and the uplink subband bandwidth indicates the number of RBs occupied by the uplink subband.

[0258] Optionally, the frequency offset on the SBFD symbol may also be expressed as: represents the rounding down of the calculation result; or, the frequency offset on the SBFD symbol can also be expressed as: Indicates rounding up the calculation result.

[0259] (b) when the activated uplink BWP bandwidth is less than a third value, the frequency offset on the SBFD symbol is the frequency offset corresponding to the first index; when the activated uplink BWP bandwidth is greater than or equal to the third value, the frequency offset on the SBFD symbol is the frequency offset corresponding to the second index; the first index and the second index are related to the index corresponding to the frequency offset of the frequency hopping indicated in the frequency hopping related information.

[0260] Optionally, the first index is: mod(X+1, 2);

[0261] The second index is: mod(X+Q, 4);

[0262] Among them, X is the index corresponding to the frequency offset of the frequency hopping indicated in the frequency hopping related information; the value of Q is 1 or 2 or 3.

[0263] In this embodiment, the third value may be a preset value or a predefined value, such as 50 RBs. In the case where the frequency offset configured by the network device is applied to the uplink symbol, for an activated uplink BWP (active UL BWP) bandwidth less than 50 RBs, the frequency offset value on the SBFD symbol is the value corresponding to the index mod(X+1, 2). For an active BWP bandwidth greater than or equal to 50 RBs, the frequency offset value on the SBFD symbol is the value corresponding to the index mod(X+Q, 4), where Q=1 or 2 or 3.

[0264] As an optional embodiment, the second rule includes at least one of the following:

[0265] (a1) determining a frequency offset on an uplink symbol according to the frequency offset of the frequency hopping, the uplink BWP bandwidth, and the uplink subband bandwidth indicated in the frequency hopping related information;

[0266] Optionally, determining the frequency offset on the uplink symbol according to the frequency offset of the frequency hopping indicated in the frequency hopping related information, the uplink BWP bandwidth, and the uplink subband bandwidth includes:

[0267] The frequency offset on the uplink symbol is determined by the following formula:

[0268]

[0269] or

[0270] Wherein, M is the frequency offset of the frequency hopping indicated in the frequency hopping related information. The unit of the frequency offset M, the uplink BWP bandwidth and the uplink subband bandwidth is RB, and the uplink BWP is the uplink BWP where the frequency hopping transmission is located or the currently activated ULBWP. The uplink BWP bandwidth indicates the number of RBs occupied by the uplink BWP, and the uplink subband bandwidth indicates the number of RBs occupied by the uplink subband.

[0271] Optionally, the frequency offset on the uplink symbol may also be expressed as: represents the rounding down of the calculation result; or, the frequency offset on the uplink symbol can also be expressed as: Indicates rounding up the calculation result.

[0272] (b1) When the activated uplink BWP bandwidth is less than a third value, the frequency offset on the uplink symbol is the frequency offset corresponding to the first index; when the activated uplink BWP bandwidth is greater than or equal to the third value, the frequency offset on the uplink symbol is the frequency offset corresponding to the second index; the first index and the second index are related to the index corresponding to the frequency offset of the frequency hopping indicated in the frequency hopping related information.

[0273] Optionally, the first index is: mod(X+1, 2);

[0274] The second index is: mod(X+Q, 4);

[0275] Among them, X is the index corresponding to the frequency offset of the frequency hopping indicated in the frequency hopping related information; the value of Q is 1 or 2 or 3.

[0276] In this embodiment, the third value may be a preset value or a predefined value, such as 50 RBs. In the case where the frequency offset of the frequency hopping indicated by the network device is applied to the SBFD symbol, for an activated uplink BWP (active UL BWP) bandwidth less than 50 RBs, the frequency offset value on the uplink symbol is the value corresponding to the index mod(X+1, 2). For an active BWP bandwidth greater than or equal to 50 RBs, the frequency offset value on the uplink symbol is the value corresponding to the index mod(X+Q, 4), where Q=1 or 2 or 3.

[0277] The following example illustrates a process in which a terminal determines a frequency offset of frequency hopping on a SBFD symbol and a frequency offset of frequency hopping on an uplink symbol according to frequency hopping related information indicated by a network device.

The UE determines the frequency domain offset according to the frequency offset information configured by the network device, and also includes: determining a frequency offset set according to RRC signaling, determining an index in the frequency offset set according to the frequency offset information, and determining the frequency offset according to the frequency offset set and the index.

[0279] The UE determines the frequency offset on the SBFD symbol and the uplink symbol according to the frequency offset configured by the network device. The specific method may be any of the following:

[0280] Method a: The frequency offset M configured by the network device is applied to all uplink symbols.

[0281] For example, the frequency offset M configured by the network device is 20RBs, the UL BWP bandwidth is 200RBs, and the UL subband bandwidth is 50RBs. According to the above method, the frequency offset on the full uplink symbol is 20RBs, and the frequency offset of the SBFD symbol is Alternatively, the frequency offset of the SBFD symbol is 20 RBs, and the frequency offset of the full uplink symbol is

[0282] Method b: The frequency offset value M configured by the network device is applied to the full uplink symbol (or SBFD symbol). For an active UL BWP bandwidth less than 50 RBs, the frequency offset value on the SBFD symbol (or full uplink symbol) is a value corresponding to the index mod(X+1, 2), where X is the index corresponding to the frequency offset value M indicated by the DCI; for an active BWP bandwidth greater than or equal to 50 RBs, the frequency offset value on the SBFD symbol (or full uplink symbol) is a value corresponding to the index mod(X+Q, 4), where Q=1 or 2 or 3, and X is the index corresponding to the frequency offset M indicated by the DCI.

[0283] For example: the frequency offset value M configured by the network device is applied to all uplink symbols. When the active UL BWP bandwidth is less than 50 RBs, the index corresponding to the frequency offset value M is index=0, then the frequency offset value on the SBFD symbol is the frequency offset value corresponding to the index mod(X+1, 2)=mod(0+1, 2)=1.

[0284] For example: the frequency offset value M configured by the network device is applied to the SBFD symbol. When the active UL BWP bandwidth is less than 50 RBs, the index index corresponding to the frequency offset value M is 1, and the frequency offset value on the entire uplink symbol is the frequency offset value corresponding to the index mod(X+1, 2)=mod(1+1, 2)=0.

[0285] For example: the frequency offset value M configured by the network device is applied to the full uplink symbol. When the active UL BWP bandwidth is greater than 50RBs, the index corresponding to the frequency offset value M is index=0, Q=2, then the frequency offset value on the SBFD symbol is the frequency offset value corresponding to index mod(index+2, 4)=mod(0+2, 4)=2.

[0286] For example: the frequency offset value M configured by the network device is applied to the SBFD symbol. When the active UL BWP bandwidth is greater than 50RBs, the index corresponding to the frequency offset value M is index=1, Q=3, then the frequency offset value on the entire uplink symbol is the frequency offset value corresponding to index mod(index+3, 4)=mod(1+3, 4)=0.

[0287] In this embodiment, the terminal can determine the frequency offset parameters of two types of symbols or time slots based on a set of frequency offset information configured by the network device, without increasing the signaling overhead, and can reduce the implementation complexity of the network device, thereby increasing the flexibility of the frequency hopping configuration and the frequency hopping gain.

[0288] As an optional embodiment, the receiving frequency hopping related information sent by the network device includes:

[0290] The method further comprises:

[0291] The length of the first field in the DCI is determined according to the bandwidth of the activated uplink BWP and / or the bandwidth of the uplink subband, where the first field is used to indicate the frequency offset information of the frequency hopping.

[0292] In this embodiment, the network device may send frequency hopping related information to the terminal through RRC signaling, DCI or RAR. When the network device sends the frequency hopping related information through DCI, for the DCI for scheduling PUSCH, the DCI for scheduling PUSCH is used to schedule UEs supporting SBFD, and the DCI includes a first field for indicating frequency offset information, and the length of the first field can be determined according to the bandwidth of the activated uplink BWP or the width of the uplink subband.

[0293] Optionally, determining the length of the first field in the DCI according to the bandwidth of the activated uplink BWP and / or the bandwidth of the uplink subband includes:

[0294] When the PUSCH scheduled by the DCI is within the uplink subband range and the bandwidth of the activated uplink BWP or the bandwidth of the uplink subband is less than the fourth value, the length of the first field is 1 bit;

[0295] When the PUSCH scheduled by the DCI is within the uplink subband range and the bandwidth of the activated uplink BWP or the bandwidth of the uplink subband is greater than or equal to the fourth value, the length of the first field is 2 bits.

[0296] In this embodiment, the fourth value may be a preset value or a predefined value, and the fourth value is, for example, 50 RBs. If the uplink resource scheduled by the DCI is within the UL subband range, the length of the first field may be determined according to the activated uplink BWP or uplink subband. Taking the fourth value of 50 RBs as an example, when the width of the uplink activated BWP is less than 50 RBs, the length of the first subband is set to 1 bit, indicating one of the two high-level configured frequency offsets. When the width of the uplink activated BWP is greater than or equal to 50 RBs, the length of the first subband is set to 2 bits, and the frequency offset is indicated by the high bit or the low bit of the 2 bits.

[0297] Optionally, the DCI also includes a second field, where the second field is used to indicate that the PUSCH scheduled by the DCI is within an uplink subband range or the scheduled PUSCH is within an activated uplink BWP range.

[0298] In this embodiment, the network device may also use the second field in the DCI to indicate whether the uplink resource scheduled by the current DCI is within the UL subband range or within the UL active BWP range.

[0299] The following example illustrates a method for determining the length of a field indicating frequency offset information.

[0300] For the DCI for scheduling PUSCH, the DCI for scheduling PUSCH is used to schedule UE supporting SBFD, and the length of the first field for indicating the frequency offset of frequency hopping in the DCI is determined according to the bandwidth of the uplink activated BWP.

[0301] Optionally, no matter whether the PUSCH scheduled by the DCI is within the UL subband range or within the uplink activated BWP range, the length of the first field is determined according to the activated uplink BWP.

[0302] Specifically: when the width of the activated uplink BWP is less than 50 RBs, the length of the first field is 1 bit, indicating one of the two frequency offsets configured by the high-level layer; when the bandwidth of the activated uplink BWP is greater than or equal to 50 RBs, the length of the first field is 2 bits, indicating one of the four frequency offsets configured by the high-level layer.

[0303] Optionally, when the PUSCH scheduled by the DCI is within the UL subband range, the length of the first field is determined according to the activated uplink BWP. For example, when the bandwidth of the activated uplink BWP is greater than or equal to 50 RBs and the bandwidth of the UL subband is less than 50 RBs, the length of the first field is 2 bits.

[0304] Optionally, for the DCI scheduling PUSCH, the DCI scheduling PUSCH is used to schedule UE supporting SBFD, when the PUSCH scheduled by the DCI is located within the UL subband range, the length of the frequency offset indication field of the frequency hopping in the DCI is determined according to the bandwidth of the uplink subband.

[0305] For example, when the width of the uplink subband is less than 50 RBs, the length of the first field is 1 bit, indicating one of the two frequency offsets configured by the higher layer;

[0306] When the bandwidth of the uplink subband is greater than or equal to 50 RBs, the length of the first field is 2 bits, indicating one of the four frequency offsets configured by the higher layer.

[0307] Optionally, the network device may indicate, through an indication field in the DCI, whether the uplink resource currently scheduled by the DCI is within a UL subband range or within a UL active BWP range.

[0308] In this embodiment, the terminal determines the length of the field used to indicate the frequency offset according to the bandwidth of the BWP and / or the bandwidth of the uplink subband.

[0309] In an embodiment of the present application, the terminal can determine the frequency hopping parameters of two time slot types, namely, the SBFD time slot and the uplink time slot, based on a set of frequency hopping related information indicated by the network device. Without increasing the signaling overhead, the implementation complexity of the network device is reduced, and the flexibility of the frequency hopping configuration and the frequency hopping gain are increased.

[0310] like Figure 2 As shown, the embodiment of the present application also provides a method for determining frequency hopping information, which is applied to a network device, including:

[0312] The frequency hopping related information indicates whether frequency hopping is enabled and / or frequency offset information of frequency hopping.

[0313] The frequency hopping related information sent by the network device may include indication information of whether to enable frequency hopping and / or frequency offset information of frequency hopping. The terminal determines whether to enable frequency hopping on SBFD symbols and / or the frequency offset information of frequency hopping on SBFD symbols, and the terminal determines whether to enable frequency hopping on uplink symbols and / or the frequency offset information of frequency hopping on uplink symbols.

[0314] The frequency hopping related information may be used to indicate whether frequency hopping is enabled, for example: if the frequency hopping related information includes 1, it indicates that frequency hopping is enabled; if the frequency hopping related information includes 0, it indicates that frequency hopping is not enabled. The opposite is also possible, and the specific indication method is not limited here.

[0315] It should be noted that the SBFD symbols in the embodiments of the present application may also be replaced by SBFD time slots, wherein the SBFD time slots are time slots in which all or part of the symbols are SBFD symbols, and the uplink symbols may also be replaced by uplink time slots, that is, the network device determines the frequency hopping related information on the SBFD time slot and the frequency hopping related information on the uplink time slot. The embodiments of the present application may be applied to multi-slot PUSCH transmission, PUSCH repeated transmission and / or PUSCH configuration transmission, etc., and the specific application scenarios are not limited.

[0320] In this embodiment, the network device may send the frequency hopping related information to the terminal through RRC signaling, DCI or RAR. When the network device sends the frequency hopping related information through DCI, for the DCI for scheduling PUSCH, the DCI for scheduling PUSCH is used to schedule UEs supporting SBFD, and the DCI includes a first field for indicating frequency offset information, and the length of the first field can be determined according to the bandwidth of the activated uplink BWP or the width of the uplink subband.

[0323] When the PUSCH scheduled by the DCI is within the uplink subband range and the bandwidth of the activated uplink BWP or the bandwidth of the uplink subband is greater than or equal to the fourth value, the length of the first field is 2 bits.

[0324] In this embodiment, the fourth value may be a preset value or a predefined value, and the fourth value is, for example, 50 RBs. If the PUSCH scheduled by the DCI is within the UL subband range, the length of the first field may be determined according to the activated uplink BWP or uplink subband. Taking the fourth value of 50 RBs as an example, when the width of the uplink activated BWP is less than 50 RBs, the length of the first subband is set to 1 bit, indicating one of the two high-level configured frequency offsets. When the width of the uplink activated BWP is greater than or equal to 50 RBs, the length of the first subband is set to 2 bits, and the frequency offset is indicated by the high bit or the low bit of the 2 bits.

[0325] Optionally, the DCI also includes a second field, where the second field is used to indicate that the PUSCH scheduled by the DCI is within an uplink subband range or the scheduled PUSCH is within an activated uplink BWP range.

[0326] In this embodiment, the network device may also use the second field in the DCI to indicate whether the uplink resource scheduled by the current DCI is within the UL subband range or within the UL active BWP range.
