[0027] The embodiments of the present disclosure provide a resource determination method, a terminal, a network device, a communication device, and a storage medium.

[0028] In a first aspect, an embodiment of the present disclosure proposes a resource determination method, which is executed by a terminal. The method includes: determining a time domain resource of a subband in each time domain unit in at least one time domain unit according to first information.

[0029] In the above embodiment, the first information can indicate the time domain resources of the subband configured by the network device on each time domain unit in at least one time domain unit. The terminal can determine the time domain resources of the subband on the time domain unit based on the first information. Accordingly, it is helpful to ensure that the terminal accurately determines the time domain resources of the subband, and then can communicate based on the subband on the time domain resources of the subband.

[0030] In combination with some embodiments of the first aspect, in some embodiments, the sub-band includes: an uplink sub-band.

[0031] In the above embodiment, an uplink subband is configured for the terminal in the time domain unit. The network can send information to the terminal in the downlink frequency domain resources of the time domain unit, and receive information sent by the terminal in the uplink subband, thereby realizing simultaneous reception and transmission of information in one time domain unit, which is conducive to improving communication efficiency.

[0032] In combination with some embodiments of the first aspect, in some embodiments, the sub-band includes: a downlink sub-band.

[0033] In the above embodiment, a downlink subband is configured for the terminal in the time domain unit. The network can send information to the terminal in the uplink frequency domain resources in the time domain unit, and receive information sent by the terminal in the uplink subband, thereby realizing simultaneous reception and transmission of information in one time domain unit, which is conducive to improving communication efficiency.

[0034] In combination with some embodiments of the first aspect, in some embodiments, the first information includes: a bitmap.

[0035] In the above embodiment, the terminal can be instructed only through the bitmap, which is beneficial to saving communication resources.

[0036] In combination with some embodiments of the first aspect, in some embodiments, the first information includes: a resource indication value.

[0037] In the above embodiment, the terminal can be instructed only through the resource indication value, which is beneficial to saving communication resources.

[0038] In combination with some embodiments of the first aspect, in some embodiments, the first information includes: a bitmap and a resource indication value.

[0039] In the above embodiment, the indication to the terminal can be implemented through the bitmap and the resource indication value, which is conducive to improving the accuracy of the indication.

[0040] In combination with some embodiments of the first aspect, in some embodiments, the first information includes at least one resource indication value.

[0041] In the above embodiment, at least one resource indication value may be used to indicate the terminal, which is beneficial to improving the accuracy of the indication.

[0042] In combination with some embodiments of the first aspect, in some embodiments, a first resource indication value in the at least one resource indication value is used to indicate a time domain resource of a subband in a first time domain unit in the at least one time domain unit.

[0043] In the above embodiment, the terminal can determine the time domain resources of the subband in each time domain unit in at least one time domain unit according to at least one resource indication value in the first information, which is conducive to ensuring the accuracy of determining the time domain resources of the subband in each time domain unit.

[0044] In combination with some embodiments of the first aspect, in some embodiments, some time domain units in the at least one time domain unit are configured with subbands, and the at least one resource indication value is used to indicate the time domain resources of the subbands in the some time domain units.

[0045] In the above embodiment, since the network device can configure subbands in some time domain units of at least one time domain unit, but not configure subbands in other time domain units, in order to save the communication resources occupied by at least one resource indication value, at least one resource indication value can be used to indicate the time domain resources of the subbands in some time domain units.

[0046] In combination with some embodiments of the first aspect, in some embodiments, the first information further includes the bitmap, wherein the bitmap is used to indicate the time domain unit in which the subband is configured in the at least one time domain unit.

[0047] In the above embodiment, the network device may indicate the time domain unit configured with the subband in at least one time domain unit through the bitmap in the first information, so that the terminal may accurately determine the time domain unit configured with the subband in at least one time domain unit according to the bitmap.

[0048] In combination with some embodiments of the first aspect, in some embodiments, the first resource indication value is further used to indicate at least one of the following: a subband is configured in the first time domain unit; or a subband is not configured in the first time domain unit.

[0049] In combination with some embodiments of the first aspect, in some embodiments, the first resource indication value is a predefined value, used to indicate that no subband is configured in the first time domain unit.

[0050] In combination with some embodiments of the first aspect, in some embodiments, the first resource indication value includes a value other than a predefined value, and is used to indicate that a subband is configured in the first time domain unit.

[0051] In the above embodiment, since the network device can configure subbands in some time domain units of at least one time domain unit, but not configure subbands in other time domain units, in order to enable the terminal to determine which time domain unit has no subband configured, the network device can set the first resource indication value associated with the first time domain unit to a predefined value when no subband is configured in the first time domain unit, so that after receiving the first resource indication value, the terminal can determine that no subband is configured in the first time domain unit associated with the first resource indication value.

[0052] In combination with some embodiments of the first aspect, in some embodiments, the first information includes a resource indication value.

[0053] In combination with some embodiments of the first aspect, in some embodiments, the resource indication value is used to indicate the time domain resource of the subband in each time domain unit in the at least one time domain unit.

[0054] In the above embodiment, since only one resource indication value can indicate the time domain resource of the subband in each time domain unit in at least one time domain unit, the number of resource indication values ​​in the first information is relatively small, which is conducive to saving communication resources.

[0055] In combination with some embodiments of the first aspect, in some embodiments, the method further includes: determining, based on the first information, that the time domain resources of the uplink subband in the first time domain unit in the at least one time domain unit include uplink time domain resources, and determining that no uplink subband is configured in the uplink time domain resources.

[0056] In the above embodiment, although the terminal determines that the time domain resources of the uplink subband in the first time domain unit in at least one time domain unit include the uplink time domain resources based on the resource indication value in the first information, this is generally due to the fact that the type of symbols in each time domain unit is different and the accuracy of the resource indication value for each time domain unit is limited. In fact, the network device does not reconfigure the uplink subband on the uplink time domain resources, so the terminal can determine that the uplink subband is not configured in the uplink time domain resources, thereby accurately determining the time domain resources of the uplink subband in the time domain unit.

[0057] In combination with some embodiments of the first aspect, in some embodiments, the method further includes: determining, based on the first information, that the time domain resources of the downlink subband in the first time domain unit in the at least one time domain unit include downlink time domain resources, and determining that no downlink subband is configured in the downlink time domain resources.

[0058] In the above embodiment, although the terminal determines that the time domain resources of the downlink subband in the first time domain unit in at least one time domain unit include the downlink time domain resources based on the resource indication value in the first information, this is generally due to the fact that the type of symbols in each time domain unit is different and the accuracy of the resource indication value for each time domain unit is limited. In fact, the network device does not configure the downlink subband on the downlink time domain resources, so the terminal can determine that the downlink subband is not configured in the downlink time domain resources, thereby accurately determining the time domain resources of the downlink subband in the time domain unit.

[0059] In combination with some embodiments of the first aspect. In some embodiments, the method further includes: determining, based on the first information, that the time domain resources of the subband in the first time domain unit in the at least one time domain unit include flexible time domain resources, and determining that some time domain resources in the flexible time domain resources are not configured with the subband.

[0060] In the above embodiment, even if the network device actually configures a subband on each time domain resource in the flexible time domain resources where the subband is located, the terminal can still determine that some time domain resources in the flexible time domain resources where the subband is located are not configured with subbands, so that the user can switch between uplink and downlink using some time domain resources, which is conducive to ensuring good communication effects.

[0061] In combination with some embodiments of the first aspect, in some embodiments, the first information further includes the bitmap, wherein the bitmap is used to indicate the time domain unit in which the subband is configured in the at least one time domain unit.

[0062] In the above embodiment, the network device indicates the bitmap to the terminal, which helps ensure that the terminal accurately determines the time domain unit configured with the subband in the at least one time domain unit.

[0063] In combination with some embodiments of the first aspect, in some embodiments, the resource indication value includes at least one of the following: a starting position; and a duration.

[0064] In the above embodiment, the terminal is facilitated to determine the time domain resources according to the starting position and the duration.

[0065] In combination with some embodiments of the first aspect, in some embodiments, the first information includes a bitmap.

[0066] In combination with some embodiments of the first aspect.

[0067] In combination with some embodiments of the first aspect, in some embodiments, the method further comprises: each bit in the bitmap indicates a second value, and determining that no subband is configured in each time domain unit in at least one time domain unit.

[0068] In the above embodiment, the network device may set the position of each bit in the bitmap to the first value. After receiving the first indication information, the terminal, upon determining that each bit in the bitmap indicates the first value, may determine that the time domain resources of the subband in each time domain unit in the at least one time domain unit are all the time domain resources in the time domain unit in which the subband is located. Accordingly, the time domain resources of the subband in each time domain unit in the at least one time domain unit can be indicated using a single bitmap, which is beneficial for saving communication resources.

For example, if an uplink subband is configured in a downlink time slot, the network device can conduct uplink communication within the uplink subband and downlink communication within frequency domain resources outside the uplink subband during the downlink time slot. For example, if an uplink subband is configured in a flexible time slot, the network device can conduct uplink communication within the uplink subband and downlink communication within frequency domain resources outside the uplink subband during the flexible time slot.

[0137] In some embodiments, the sub-band includes at least one of the following: an uplink sub-band; a downlink sub-band.

[0150] In some embodiments, the first resource indication value is a predefined value, used to indicate that no subband is configured in the first time domain unit.

[0157] In some embodiments, the resource indication value may only include the duration. In a further embodiment, the starting position of the resource indication value may be pre-configured by the network device for the terminal, or may be agreed upon by a protocol.

[0159] Each bit in the bitmap indicates a first value, and determines that the time domain resources of the subband in each time domain unit in the at least one time domain unit are all time domain resources in the time domain unit in which the subband is located;

[0160] Each bit in the bitmap indicates a second value, determining that no subband is configured in each time domain unit in at least one time domain unit.

[0161] In some embodiments, a bitmap is used to determine that the time domain resources of a subband in each time domain unit in at least one time domain unit are all time domain resources in the time domain unit where the subband is located, wherein each bit in the bitmap indicates a first value.

[0169] In some embodiments, the terminal determines, based on the first information, that the time domain resources of the subband in the first time domain unit in at least one time domain unit include flexible time domain resources, and determines that some time domain resources in the flexible time domain resources are not configured with subbands.

[0170] In some embodiments, the first information includes a bitmap.

[0171] In some embodiments, each bit in the bitmap indicates a first value, and the terminal determines that the time domain resources of the subband in each time domain unit in at least one time domain unit are all time domain resources in the time domain unit where the subband is located.

[0172] In some embodiments, each bit in the bitmap indicates a second value, and the terminal determines that no subband is configured in each time domain unit in the at least one time domain unit.

[0173] The communication method involved in the embodiments of the present disclosure may include at least one of steps S201 to S202. For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, and step S201 + step S202 may be implemented as independent embodiments, but the present invention is not limited thereto.

[0174] In some embodiments, steps S201 and S202 may be performed in an interchangeable order or simultaneously.

[0175] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0176] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0177] For the related implementations of the terminal and the network device in FIG2 , please refer to the embodiments below, which will not be described in detail in this disclosure.

[0178] The embodiments of the present disclosure provide a resource determination method. Figure 3 is a schematic flow chart illustrating a resource determination method according to an embodiment of the present disclosure. The resource determination method illustrated in this embodiment can be executed by a terminal. The terminal can communicate with a network device.

[0179] As shown in FIG3 , the resource determination method may include the following steps:

[0180] In step S301, a time domain resource of a subband in each time domain unit in at least one time domain unit is determined according to first information.

[0181] It should be noted that the embodiment shown in FIG. 3 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0182] In some embodiments, the network device can configure a subband for the terminal on the frequency domain resources corresponding to the time domain resources. The subband and the time domain resources where the subband is located can correspond to different communication directions. Accordingly, the network device can communicate in different directions on the time domain unit configured with the subband, for example, full-duplex communication can be achieved, which is conducive to improving communication efficiency.

[0183] According to an embodiment of the present disclosure, the first information can indicate the time domain resources of the subband configured by the network device on each time domain unit in at least one time domain unit. The terminal can determine the time domain resources of the subband on the time domain unit based on the first information. Accordingly, it is beneficial to ensure that the terminal accurately determines the time domain resources of the subband, and then can communicate based on the subband on the time domain resources of the subband.

[0184] In some embodiments, the sub-band includes at least one of the following: an uplink sub-band; a downlink sub-band.

[0185] For example, the network device may configure an uplink subband for the terminal in a first type of time domain unit, wherein the frequency domain resources corresponding to the first type of time domain unit include downlink frequency domain resources. The first type of time domain unit includes at least one of the following: a flexible time domain unit and a downlink time domain unit.

[0186] Since the frequency domain resources corresponding to the first type of time domain unit may include downlink frequency domain resources, on this basis, an uplink sub-band is configured for the terminal in the first type of time domain unit. In the first type of time domain unit, the network device can send information to the terminal in the downlink frequency domain resources and receive information sent by the terminal in the uplink sub-band, thereby realizing simultaneous reception and transmission of information in one time domain unit, which is conducive to improving communication efficiency.

[0187] For example, the network device may configure a downlink subband for the terminal in a second type of time domain unit, wherein the frequency domain resources corresponding to the second type of time domain unit include uplink frequency domain resources. The second type of time domain unit includes at least one of the following: a flexible time domain unit and an uplink time domain unit.

[0188] Since the frequency domain resources corresponding to the second type of time domain unit may include uplink frequency domain resources, on this basis, a downlink sub-band is configured for the terminal in the second type of time domain unit. The network device can receive information sent by the terminal in the uplink frequency domain resources and send information to the terminal in the downlink sub-band in the second type of time domain unit, thereby realizing simultaneous reception and transmission of information in one time domain unit, which is conducive to improving communication efficiency.

[0189] It should be noted that the terminals corresponding to the network device simultaneously receiving and sending information in one time domain unit may be different terminals, or may be the same terminal.

[0190] It should be noted that the time domain unit in the embodiments of the present disclosure includes at least one of the following: a symbol, a time slot, a frame, and a subframe, wherein the symbol may be an OFDM (Orthogonal Frequency Division Multiplexing) symbol. The subsequent embodiments mainly illustrate the technical solutions of the present disclosure when the time domain unit includes a time slot.

[0191] In some embodiments, the first information includes at least one of the following: a bitmap; a resource indicator value (RIV), wherein the resource indicator value may also be referred to as a start and length indicator value (SLIV).

[0192] In some embodiments, the resource indication value includes at least one of the following: a starting position; and a duration.

[0193] The starting position indicates the starting position of the subband time domain resource in the time domain unit, and the duration indicates the duration of the subband time domain resource in the time domain unit. The terminal can determine the time domain resource of the subband in the time domain unit based on the starting position and the duration.

[0194] In some embodiments, the resource indication value indicated by the first information may only include a starting position. In this case, the duration of the resource indication value may be pre-configured by the network device for the terminal or agreed upon by a protocol.

[0195] In some embodiments, the resource indication value indicated by the first information may only include the duration. In this case, the starting position of the resource indication value may be pre-configured by the network device for the terminal or agreed upon by the protocol.

[0196] The following uses several embodiments to exemplify several situations, such as the first information including a bitmap and a resource indication value, the first information including only a resource indication value, and the first information including only a bitmap.

[0197] In some embodiments, the first information includes at least one resource indication value. For at least one time domain unit, the network device may configure subbands in all time domain units, or may configure subbands in some time domain units, and the at least one resource indication value may indicate the time domain resources of the subband in the time domain unit in which the subband is configured.

[0198] In some embodiments, a first resource indication value in the at least one resource indication value is used to indicate a time domain resource of a subband in a first time domain unit in the at least one time domain unit.

[0199] In some embodiments, there may be an association relationship between the resource indication value and the time domain unit. The association relationship may be pre-configured by the network device, or the association relationship may be agreed upon by a protocol.

[0200] The terminal may determine, based on the association between the resource indication value and the time domain unit, which time domain unit in which each resource indication value in the at least one resource indication value specifically indicates the time domain resource of the subband.

[0201] For example, when the resource indication value indicates a time domain resource in a subband for each time domain unit in at least one time domain unit, the association relationship between the resource indication value and the time domain unit may include: the at least one resource indication value is associated with the at least one time domain unit from front to back in the time domain in the first information. Of course, the association relationship is not limited to this and can be set as needed. For example, the time domain unit identifier can also be associated with the resource indication value.

[0202] For example, taking at least one time domain unit including 10 time slots (for example, slot#0 to slot#9) as an example, at least one resource indication value may include 10 resource indication values, wherein the first resource indication value is used to indicate the time domain resources of the subband on the first time slot (slot#0), the second resource indication value is used to indicate the time domain resources of the subband on the second time slot (slot#1),..., the tenth resource indication value is used to indicate the time domain resources of the subband on the tenth time slot (slot#9).

[0203] The time domain resources of a subband in a time slot may be the symbols corresponding to the subband in the time slot. For example, in the above example, the third resource indicator value indicates the time domain resources of the subband in the third time slot (slot #2). Based on the third resource indicator value, the terminal may determine that the time domain resources of the subband in the third time slot (e.g., including 14 symbols) are symbols 1 to 8.

[0204] Accordingly, the terminal can determine the time domain resources of the subband in each time domain unit in at least one time domain unit according to at least one resource indication value in the first information. In this case, the first indication information can only include the resource indication value without including the bitmap.

[0205] In some embodiments, the first resource indication value is further used to indicate at least one of the following:

[0206] At least one time domain unit is configured with a subband time domain unit;

[0207] At least one time domain unit is not configured with a time domain unit of a subband.

[0208] In some embodiments, the first resource indication value is a predefined value, used to indicate that no subband is configured in the first time domain unit. In some embodiments, the first resource indication value includes a value other than the predefined value, used to indicate that no subband is configured in the first time domain unit. For example, the predefined value may be preconfigured by a network device or agreed upon by a protocol.

[0209] When the resource indication value indicates the time domain resources in the subband for each time domain unit in at least one time domain unit, since the network device can configure the subband in some time domain units of at least one time domain unit, but not configure the subband in other time domain units, in order to enable the terminal to determine which time domain unit has no subband configured, the network device can set the first resource indication value associated with the first time domain unit to a predefined value when the subband is not configured in the first time domain unit, so that after receiving the first resource indication value, the terminal can determine that the subband is not configured in the first time domain unit associated with the first resource indication value.

[0210] For example, the first resource indication value includes a first starting position and a first duration, and the predefined value may be 0 or 1. Taking the predefined value of 0 as an example, when the first starting position and the first duration are both 0, the terminal may determine that no subband is configured in the first time domain unit associated with the first resource indication value; when the first starting position and the first duration are not both 0, the terminal may determine that a subband is configured in the first time domain unit associated with the first resource indication value, and may determine the time domain resource of the subband based on the first starting position and the first duration.

[0211] In some embodiments, some time domain units in at least one time domain unit are configured with subbands, and at least one resource indication value is used to indicate the time domain resources of the subbands in the some time domain units.

[0212] Since the network device can configure subbands in some time domain units of at least one time domain unit, but not configure subbands in other time domain units, in order to save the communication resources occupied by at least one resource indication value, at least one resource indication value can be used to indicate the time domain resources of the subbands in some time domain units.

[0213] FIG4 is a schematic diagram showing a time domain unit according to an embodiment of the present disclosure.

[0214] As shown in FIG4 , the network device may configure a time division duplexing (TDD) time slot structure for the terminal, for example, by configuring the above time slot structure for the terminal through the time division duplexing uplink and downlink common configuration (tdd-UL-DL-ConfigurationCommon) carried in the system information block (SIB).

[0215] The terminal can determine the type of time slot based on the time slot structure, where the time slot type includes at least one of the following: downlink time slot, flexible time slot, and uplink time slot. For example, as shown in Figure 4, the time slot structure can be DDFFFFFFUU, where D represents downlink, F represents flexible, and U represents downlink. In other words, the TDD time slot structure can include a cycle with 10 time slots, of which the first and second time slots (slot#0 to slot#1) are downlink time slots, the third to eighth time slots (slot#2 to slot#7) are flexible time slots, and the ninth to tenth time slots (slot#8 to slot#9) are uplink time slots.

[0216] The terminal may also determine the type of each symbol in the flexible time slot based on the time slot structure, where the symbol type includes at least one of the following: a downlink symbol, a flexible symbol, and an uplink symbol. The flexible symbol includes at least one of the following: a dynamic flexible symbol and a semi-static flexible symbol (hereinafter referred to as a semi-flexible symbol).

[0217] For example, slot#3 among the 10 time slots shown in Figure 4 contains 14 symbols (not specifically shown in the figure). The terminal can determine that the type of symbols in slot#3 is DDDDDDDDFUUUUU based on the time slot structure, that is, the 1st to 8th symbols are downlink symbols, the 9th symbol is a flexible symbol, and the 10th to 14th symbols are uplink symbols.

[0218] In some embodiments, the first information further includes a bitmap, wherein the bitmap is used to indicate at least one of the following:

[0219] At least one time domain unit is configured with a subband time domain unit;

[0220] At least one time domain unit is not configured with a time domain unit of a subband.

[0221] Take, for example, a bitmap used to indicate the time domain units configured with subbands in at least one time domain unit. For example, when at least one resource indication value is used to indicate the time domain resources of the subbands in some time domain units, the terminal needs to first determine the time domain units configured with subbands in at least one time domain unit before determining the time domain resources of the subbands indicated by the at least one resource indication value for the time domain units configured with subbands. For example, the network device may indicate the time domain units configured with subbands in at least one time domain unit using a bitmap in the first information, and the terminal may determine the time domain units configured with subbands in at least one time domain unit based on the bitmap.

[0222] In some embodiments, the bitmap may include at least one bit. For example, the number of bits in the bitmap is the same as the number of time domain units in the at least one time domain unit. For example, if the at least one time domain unit is n time domain units, the bitmap may include n bits, where the i-th bit is used to indicate whether a subband is configured for the i-th time domain unit, where 1≤i≤n. For example, a bit of 1 may indicate that a subband is configured, and a bit of 0 may indicate that a subband is not configured.

[0223] For example, as shown in Figure 4, at least one time domain unit includes 10 time slots, and the bitmap can be 11110000000000. Based on the bitmap, the terminal can determine that the first four time slots (slot#0 to slot#3) of the 10 time slots are configured with uplink subbands. Based on this, the first information can also include four resource indicator values, where the first resource indicator value is used to indicate the time domain resources of the uplink subband in slot#0, the second resource indicator value is used to indicate the time domain resources of the uplink subband in slot#1, the third resource indicator value is used to indicate the time domain resources of the uplink subband in slot#2, and the fourth resource indicator value is used to indicate the time domain resources of the uplink subband in slot#3.

[0224] In some embodiments, the first information includes a resource indicator value. In some embodiments, the resource indicator value is used to indicate the time domain resources of the subband in each time domain unit in at least one time domain unit. Accordingly, the number of resource indicator values ​​in the first information is relatively small, which is conducive to saving communication resources.

[0225] Taking the time slot structure shown in Figure 4 as an example, for example, the resource indication value in the first information indicates that the time domain resources of the subband are the 7th to 10th symbols, then the terminal can determine that in each time slot configured with an uplink subband, the time domain resources of the uplink subband in the time slot are the 7th to 10th symbols.

[0226] FIG5 is a schematic flow chart of another resource determination method according to an embodiment of the present disclosure. The method shown in this embodiment can be executed by a terminal. As shown in FIG5 , the resource determination method further includes:

[0227] In step S501, it is determined based on the first information that the time domain resources of the uplink subband in the first time domain unit in at least one time domain unit include uplink time domain resources, and it is determined that no uplink subband is configured in the uplink time domain resources; and / or, it is determined based on the first information that the time domain resources of the downlink subband in the first time domain unit in at least one time domain unit include downlink time domain resources, and it is determined that no downlink subband is configured in the downlink time domain resources.

[0228] It should be noted that the embodiment shown in FIG. 5 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0229] In some embodiments, the network device indicates the time domain resources of the subband in each time domain unit in at least one time domain unit through a resource indication value. When the at least one time domain unit is multiple time domain units, the type of symbols in each time domain unit may be different, which will cause the time domain of the subband indicated by the resource indication value to be used differently for each time domain unit.

[0230] Taking the subband including the uplink subband as an example, when the terminal determines that the time domain resources of the uplink subband in the first time domain unit in at least one time domain unit include the uplink time domain resources based on the resource indication value in the first information, since the time domain resources corresponding to the uplink time domain resources are all uplink resources, the network device does not need to configure the uplink subband on the uplink time domain resources.

[0231] Therefore, although the terminal determines that the time domain resources of the uplink subband in the first time domain unit in at least one time domain unit include the uplink time domain resources based on the resource indication value in the first information, this is generally due to the fact that the type of symbols in each time domain unit is different, and the accuracy of the resource indication value for each time domain unit is limited. In fact, the network device does not reconfigure the uplink subband on the uplink time domain resources, so the terminal can determine that the uplink subband is not configured in the uplink time domain resources, thereby accurately determining the time domain resources of the uplink subband in the time domain unit.

[0232] Taking the subband including the downlink subband as an example, when the terminal determines that the time domain resources of the downlink subband in the first time domain unit in at least one time domain unit include downlink time domain resources based on the resource indication value in the first information, since the time domain resources corresponding to the downlink time domain resources are all downlink resources, the network device does not need to configure the downlink subband on the downlink time domain resources.

[0233] Therefore, although the terminal determines that the time domain resources of the downlink subband in the first time domain unit in at least one time domain unit include downlink time domain resources based on the resource indication value in the first information, this is generally due to the fact that the type of symbols in each time domain unit is different, and the accuracy of the resource indication value for each time domain unit is limited. In fact, the network device does not configure the downlink subband on the downlink time domain resource, so the terminal can determine that the downlink subband is not configured in the downlink time domain resource, thereby accurately determining the time domain resources of the downlink subband in the time domain unit.

[0234] For example, taking slot #1 and slot #2 in the time slot structure shown in Figure 4 as an example, slot #1 is a downlink time slot, and all symbols therein are downlink symbols; slot #2 is a flexible time slot, and the symbol type is DDDDDDDDFUUUUU, that is, symbols 1 to 8 are downlink symbols, symbol 9 is a flexible symbol, and symbols 10 to 14 are uplink symbols. The resource indicator value in the first information indicates that the time domain resources of the subband are symbols 7 to 10.

[0235] For slot #1, the 7th to 10th symbols are all downlink symbols and do not include uplink time domain resources. Therefore, the terminal can determine that in slot 1 #1, the time domain resources of the uplink subband are all downlink symbols from the 7th to the 10th symbols.

[0236] For slot#2, among the 7th to 10th symbols, the 7th and 8th symbols are downlink symbols, the 9th symbol is a flexible symbol, and the 10th symbol is an uplink symbol. That is, the 7th to 9th symbols are not uplink time domain resources, and the 10th symbol is an uplink time domain resource. Then the terminal can determine that in slot1#2, the time domain resources of the uplink subband are the 7th to 9th symbols, and the uplink subband is not configured on the 10th time domain symbol.

[0237] In some embodiments, the first information further includes a bitmap, wherein the bitmap is used to indicate at least one of the following:

[0238] At least one time domain unit is configured with a subband time domain unit;

[0239] At least one time domain unit is not configured with a time domain unit of a subband.

[0240] Take, for example, a bitmap used to indicate the time domain units configured with subbands in at least one time domain unit. For example, when a resource indication value is used to indicate the time domain resources of the subbands in each time domain unit in at least one time domain unit, the terminal needs to first determine the time domain units configured with subbands in the at least one time domain unit before determining the time domain resources of the subbands indicated by the resource indication value for the time domain units configured with subbands. For example, the network device may indicate the time domain units configured with subbands in the at least one time domain unit using a bitmap in the first information, and the terminal may determine the time domain units configured with subbands in the at least one time domain unit based on the bitmap.

[0241] In some embodiments, the bitmap may include at least one bit. For example, the number of bits in the bitmap is the same as the number of time domain units in the at least one time domain unit. For example, if the at least one time domain unit is n time domain units, the bitmap may include n bits, where the i-th bit is used to indicate whether a subband is configured for the i-th time domain unit, where 1≤i≤n. For example, a bit of 1 may indicate that a subband is configured, and a bit of 0 may indicate that a subband is not configured.

[0242] For example, as shown in Figure 4, at least one time domain unit includes 10 time slots, and the bitmap can be 11110000000000. Based on the bitmap, the terminal can determine that the first four time slots (slot #0 to slot #3) of the 10 time slots are configured with uplink subbands. Based on this, the first information can also include a resource indication value, where the resource indication value is used to indicate the time domain resources of the uplink subbands in slot #0 to slot #3.

[0243] FIG6 is a schematic flow chart of another resource determination method according to an embodiment of the present disclosure. The method shown in this embodiment can be executed by a terminal. As shown in FIG6, the resource determination method further includes:

[0244] In step S601, it is determined according to first information that time domain resources of a subband in a first time domain unit in at least one time domain unit include flexible time domain resources, and it is determined that some time domain resources in the flexible time domain resources are not configured with subbands.

[0245] It should be noted that the embodiment shown in FIG. 6 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0246] In some embodiments, the terminal determines, based on the first information, that the time domain resources of the subband in the first time domain unit include flexible time domain resources, such as a semi-flexible symbol. Since the time domain resources subsequent to the flexible time domain resources are generally downlink time domain resources or uplink time domain resources, uplink and downlink switching may occur from the flexible time domain resources to the subsequent time domain resources. In this case, if communication is performed on the subbands in all flexible time domain resources, it is difficult to reserve time for uplink and downlink switching, which may easily affect communication performance.

[0247] Therefore, in this embodiment, even if the network device actually configures subbands on each time domain resource in the flexible time domain resources where the subband is located, the terminal can still determine that some time domain resources in the flexible time domain resources where the subband is located are not configured with subbands, so that the user can switch between uplink and downlink using some time domain resources, which is conducive to ensuring good communication effects.

[0248] For example, the flexible time domain resources where the subband is located include n semi-flexible symbols, and some of the time domain resources in the n semi-flexible symbols may be from the last semi-flexible symbol to the m-th semi-flexible symbol, where 1≤m<n. Then, the terminal can use the subband for communication in nm semi-flexible symbols among the n semi-flexible symbols, and can switch between uplink and downlink in the last semi-flexible symbols from the first to the m-th semi-flexible symbols.

[0249] In some embodiments, the first information includes a bitmap, and determining the time domain resources of the subband in each time domain unit in at least one time domain unit based on the first information includes at least one of the following:

[0250] Each bit in the bitmap indicates a first value, and determining that the time domain resources of the subband in each time domain unit in the at least one time domain unit are all time domain resources in the time domain unit in which the subband is located; wherein each bit in the bitmap indicates the first value;

[0251] Each bit in the bitmap indicates a second value, and determines that no subband is configured in each time domain unit in at least one time domain unit, wherein each bit in the bitmap indicates the second value. The first value and the second value can be different values.

[0252] In some embodiments, the first information may only include a bitmap instead of a resource indication value. Accordingly, a bitmap can be used to indicate the time domain resources of the subband in each time domain unit in at least one time domain unit. The first information contains less information, which is conducive to saving communication resources.

[0253] FIG7 is a schematic flow chart illustrating another resource determination method according to an embodiment of the present disclosure. The method illustrated in this embodiment can be executed by a terminal. As shown in FIG7 , determining the time domain resources of a subband in each time domain unit in at least one time domain unit based on first information includes:

[0254] In step S701, each bit in the bitmap indicates a first value, and it is determined that the time domain resources of the subband in each time domain unit in at least one time domain unit are all time domain resources in the time domain unit where the subband is located.

[0255] It should be noted that the embodiment shown in FIG. 7 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0256] In some embodiments, the network device may set the position of each bit in the bitmap to a first value. After receiving the first indication information, the terminal may determine that each bit in the bitmap indicates the first value and determine that the time domain resources of the subband in each time domain unit in at least one time domain unit are all the time domain resources in the time domain unit in which the subband is located. Accordingly, the time domain resources of the subband in each time domain unit in at least one time domain unit can be indicated by a single bitmap, which is beneficial for saving communication resources.

[0257] For example, at least one time domain unit is 10 time slots, the first value can be 1, and when the terminal determines that the bitmap in the first information is 1111111111, it can further determine that the time domain resources of the subband in each of the 10 time slots are all symbols in the time slot.

[0258] In some embodiments, the resource determination method further includes: each bit in the bitmap indicates a second value, and determining that no subband is configured in each time domain unit in the at least one time domain unit.

[0259] In some embodiments, the network device may set the position of each bit in the bitmap to a second value. After the terminal receives the first indication information, when it is determined that each bit in the bitmap indicates the second value, it can be determined that no subband is configured in each time domain unit in at least one time domain unit.

[0260] For example, at least one time domain unit is 10 time slots, and the second value may be 0. When the terminal determines that the bitmap in the first information is 0000000000, it may further determine that no subband is configured in each of the 10 time slots.

[0261] The embodiments of the present disclosure provide a resource determination method. Figure 8 is a schematic flow chart illustrating a resource determination method according to an embodiment of the present disclosure. The resource determination method shown in this embodiment can be executed by a network device.

[0262] As shown in FIG8 , the resource determination method may include the following steps:

[0263] In step S801, first information is sent to a terminal, where the first information is used to determine a time domain resource of a subband in each time domain unit in at least one time domain unit.

[0264] It should be noted that the embodiment shown in FIG8 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.

[0265] In some embodiments, the network device can configure a subband for the terminal on the frequency domain resources corresponding to the time domain resources. The subband and the time domain resources where the subband is located can correspond to different communication directions. Accordingly, the network device can communicate in different directions on the time domain unit configured with the subband, for example, full-duplex communication can be achieved, which is conducive to improving communication efficiency.

[0266] According to an embodiment of the present disclosure, the network device can indicate to the terminal through the first information the time domain resources of the subband configured by the network device on each time domain unit in at least one time domain unit, so that the terminal can determine the time domain resources of the subband on the time domain unit based on the first information. Accordingly, it is beneficial to ensure that the terminal accurately determines the time domain resources of the subband, and then can communicate based on the subband on the time domain resources of the subband.

[0267] In some embodiments, the sub-band includes at least one of the following: an uplink sub-band; a downlink sub-band.

[0268] For example, the network device may configure an uplink subband for the terminal in a first type of time domain unit, wherein the frequency domain resources corresponding to the first type of time domain unit include downlink frequency domain resources. The first type of time domain unit includes at least one of the following: a flexible time domain unit and a downlink time domain unit.

[0269] Since the frequency domain resources corresponding to the first type of time domain unit may include downlink frequency domain resources, on this basis, an uplink sub-band is configured for the terminal in the first type of time domain unit. In the first type of time domain unit, the network device can send information to the terminal in the downlink frequency domain resources and receive information sent by the terminal in the uplink sub-band, thereby realizing simultaneous reception and transmission of information in one time domain unit, which is conducive to improving communication efficiency.

[0270] For example, the network device may configure a downlink subband for the terminal in a second type of time domain unit, wherein the frequency domain resources corresponding to the second type of time domain unit include uplink frequency domain resources. The second type of time domain unit includes at least one of the following: a flexible time domain unit and an uplink time domain unit.

[0271] Since the frequency domain resources corresponding to the second type of time domain unit may include uplink frequency domain resources, on this basis, a downlink sub-band is configured for the terminal in the second type of time domain unit. The network device can receive information sent by the terminal in the uplink frequency domain resources and send information to the terminal in the downlink sub-band in the second type of time domain unit, thereby realizing simultaneous reception and transmission of information in one time domain unit, which is conducive to improving communication efficiency.

[0272] It should be noted that the terminals corresponding to the network device simultaneously receiving and sending information in one time domain unit may be different terminals, or may be the same terminal.

[0273] It should be noted that the time domain unit in the embodiments of the present disclosure includes at least one of the following: a symbol, a time slot, a frame, and a subframe, wherein a symbol may be an OFDM symbol. The subsequent embodiments mainly illustrate the technical solutions of the present disclosure in the case where the time domain unit includes a time slot.

[0274] In some embodiments, the first information includes at least one of the following: a bitmap; a resource indication value (RIV), wherein the resource indication value may also be referred to as a start and length indication value (SLIV).

[0275] In some embodiments, the resource indication value includes at least one of the following: a starting position; and a duration.

[0276] The starting position indicates the starting position of the subband time domain resource in the time domain unit, and the duration indicates the duration of the subband time domain resource in the time domain unit. The terminal can determine the time domain resource of the subband in the time domain unit based on the starting position and the duration.

[0277] In some embodiments, the resource indication value indicated by the first information may only include a starting position. In this case, the duration of the resource indication value may be pre-configured by the network device for the terminal or agreed upon by a protocol.

[0278] In some embodiments, the resource indication value indicated by the first information may only include the duration. In this case, the starting position of the resource indication value may be pre-configured by the network device for the terminal or agreed upon by the protocol.

[0279] The following uses several embodiments to exemplify several situations, such as the first information including a bitmap and a resource indication value, the first information including only a resource indication value, and the first information including only a bitmap.

[0280] In some embodiments, the first information includes at least one resource indication value. For at least one time domain unit, the network device may configure subbands in all time domain units, or may configure subbands in some time domain units, and the at least one resource indication value may indicate the time domain resources of the subband in the time domain unit in which the subband is configured.

[0281] In some embodiments, a first resource indication value in the at least one resource indication value is used to indicate a time domain resource of a subband in a first time domain unit in the at least one time domain unit.

[0282] In some embodiments, there may be an association relationship between the resource indication value and the time domain unit. The association relationship may be pre-configured by the network device, or the association relationship may be agreed upon by a protocol.

[0283] The network device and the terminal can determine, based on the association between the resource indication value and the time domain unit, which time domain resource of the subband in the at least one time domain unit is specifically indicated by each resource indication value in the at least one resource indication value.

[0284] For example, when the resource indication value indicates a time domain resource in a subband for each time domain unit in at least one time domain unit, the association relationship between the resource indication value and the time domain unit may include: the at least one resource indication value is associated with the at least one time domain unit from front to back in the time domain in the first information. Of course, the association relationship is not limited to this and can be set as needed. For example, the time domain unit identifier can also be associated with the resource indication value.

[0285] For example, taking at least one time domain unit including 10 time slots (for example, slot#0 to slot#9) as an example, at least one resource indication value may include 10 resource indication values, wherein the first resource indication value is used to indicate the time domain resources of the subband on the first time slot (slot#0), the second resource indication value is used to indicate the time domain resources of the subband on the second time slot (slot#1),..., the tenth resource indication value is used to indicate the time domain resources of the subband on the tenth time slot (slot#9).

[0286] The time domain resources of a subband in a time slot may be the symbols corresponding to the subband in the time slot. For example, in the above example, the third resource indicator value indicates the time domain resources of the subband in the third time slot (slot #2). Based on the third resource indicator value, the terminal may determine that the time domain resources of the subband in the third time slot (e.g., including 14 symbols) are symbols 1 to 8.

[0287] Accordingly, the network device can instruct the terminal to determine the time domain resources of the subband in each time domain unit in at least one time domain unit through at least one resource indication value in the first information. In this case, the first indication information can only include the resource indication value without including the bitmap.

[0288] In some embodiments, the first resource indication value is further used to indicate at least one of the following:

[0289] At least one time domain unit is configured with a subband time domain unit;

[0290] At least one time domain unit is not configured with a time domain unit of a subband.

[0291] In some embodiments, the first resource indication value is a predefined value, used to indicate that no subband is configured in the first time domain unit. In some embodiments, the first resource indication value includes a value other than the predefined value, used to indicate that no subband is configured in the first time domain unit. For example, the predefined value may be preconfigured by a network device or agreed upon by a protocol.

[0292] When the resource indication value indicates the time domain resources in the subband for each time domain unit in at least one time domain unit, since the network device can configure the subband in some time domain units of at least one time domain unit, but not configure the subband in other time domain units, in order to enable the terminal to determine which time domain unit has no subband configured, the network device can set the first resource indication value associated with the first time domain unit to a predefined value when the subband is not configured in the first time domain unit, so that after receiving the first resource indication value, the terminal can determine that the subband is not configured in the first time domain unit associated with the first resource indication value.

[0293] For example, the first resource indication value includes a first starting position and a first duration. For example, the predefined value may be 0 or 1. Taking the predefined value as 0 as an example, when the first starting position and the first duration are both 0, the terminal may determine that no subband is configured in the first time domain unit associated with the first resource indication value. When at least one of the first starting position and the first duration is not a predefined value, such as a value other than 0, the terminal may determine that a subband is configured in the first time domain unit associated with the first resource indication value, and may determine the time domain resource of the subband based on the first starting position and the first duration.

[0294] In some embodiments, some time domain units in at least one time domain unit are configured with subbands, and at least one resource indication value is used to indicate the time domain resources of the subbands in the some time domain units.

[0295] Since the network device can configure subbands in some time domain units of at least one time domain unit, but not configure subbands in other time domain units, in order to save the communication resources occupied by at least one resource indication value, at least one resource indication value can be used to indicate the time domain resources of the subbands in some time domain units.

[0296] As shown in FIG4 , the network device may configure a time division duplex (TDD) time slot structure for the terminal, for example, by configuring the time division duplex uplink and downlink common configuration for the terminal via a system information block (SIB).

[0297] The terminal can determine the type of time slot based on the time slot structure, where the time slot type includes at least one of the following: downlink time slot, flexible time slot, and uplink time slot. For example, as shown in Figure 4, the time slot structure can be DDFFFFFFUU, where D represents downlink, F represents flexible, and U represents downlink. In other words, the TDD time slot structure can include a cycle with 10 time slots, of which the first and second time slots (slot#0 to slot#1) are downlink time slots, the third to eighth time slots (slot#2 to slot#7) are flexible time slots, and the ninth to tenth time slots (slot#8 to slot#9) are uplink time slots.

[0298] The terminal may also determine the type of each symbol in the flexible time slot based on the time slot structure, where the symbol type includes at least one of the following: a downlink symbol, a flexible symbol, and an uplink symbol. The flexible symbol includes at least one of the following: a dynamic flexible symbol and a semi-static flexible symbol (hereinafter referred to as a semi-flexible symbol).

[0299] For example, slot#3 among the 10 time slots shown in Figure 4 contains 14 symbols (not specifically shown in the figure). The terminal can determine that the type of symbols in slot#3 is DDDDDDDDFUUUUU based on the time slot structure, that is, the 1st to 8th symbols are downlink symbols, the 9th symbol is a flexible symbol, and the 10th to 14th symbols are uplink symbols.

[0300] In some embodiments, the first information further includes a bitmap, which is used to indicate at least one of the following:

[0301] At least one time domain unit is configured with a subband time domain unit;

[0302] At least one time domain unit is not configured with a time domain unit of a subband.

[0303] Taking the example of a bitmap used to indicate time domain units configured with subbands in at least one time domain unit, for example, when at least one resource indication value is used to indicate time domain resources of subbands in some time domain units, the terminal needs to first determine the time domain units configured with subbands in at least one time domain unit before determining the time domain resources of the subbands indicated by the at least one resource indication value for the time domain units configured with subbands.

[0304] For example, the network device may indicate the time domain unit configured with the subband in at least one time domain unit through a bitmap in the first information, and the terminal may determine the time domain unit configured with the subband in at least one time domain unit according to the bitmap.

[0305] In some embodiments, the bitmap may include at least one bit. For example, the number of bits in the bitmap is the same as the number of time domain units in the at least one time domain unit. For example, if the at least one time domain unit is n time domain units, the bitmap may include n bits, where the i-th bit is used to indicate whether a subband is configured for the i-th time domain unit, where 1≤i≤n. For example, a bit of 1 may indicate that a subband is configured, and a bit of 0 may indicate that a subband is not configured.

[0306] For example, as shown in Figure 4, at least one time domain unit includes 10 time slots, and the bitmap can be 11110000000000. Based on the bitmap, the terminal can determine that the first four time slots (slot#0 to slot#3) of the 10 time slots are configured with uplink subbands. Based on this, the first information can also include four resource indicator values, where the first resource indicator value is used to indicate the time domain resources of the uplink subband in slot#0, the second resource indicator value is used to indicate the time domain resources of the uplink subband in slot#1, the third resource indicator value is used to indicate the time domain resources of the uplink subband in slot#2, and the fourth resource indicator value is used to indicate the time domain resources of the uplink subband in slot#3.

[0307] In some embodiments, the first information includes a resource indicator value. In some embodiments, the resource indicator value is used to indicate the time domain resources of the subband in each time domain unit in at least one time domain unit. Accordingly, the number of resource indicator values ​​in the first information is relatively small, which is conducive to saving communication resources.

[0308] Taking the time slot structure shown in Figure 4 as an example, for example, the resource indication value in the first information indicates that the time domain resources of the subband are the 7th to 10th symbols, then the terminal can determine that in each time slot configured with an uplink subband, the time domain resources of the uplink subband in the time slot are the 7th to 10th symbols.

[0309] In some embodiments, the first information further includes a bitmap, wherein the bitmap is used to indicate at least one of the following:

[0310] At least one time domain unit is configured with a subband time domain unit;

[0311] At least one time domain unit is not configured with a time domain unit of a subband.

[0312] Take, for example, a bitmap used to indicate the time domain units configured with subbands in at least one time domain unit. For example, when a resource indication value is used to indicate the time domain resources of the subbands in each time domain unit in at least one time domain unit, the terminal needs to first determine the time domain units configured with subbands in the at least one time domain unit before determining the time domain resources of the subbands indicated by the resource indication value for the time domain units configured with subbands. For example, the network device may indicate the time domain units configured with subbands in the at least one time domain unit using a bitmap in the first information, and the terminal may determine the time domain units configured with subbands in the at least one time domain unit based on the bitmap.

[0313] In some embodiments, the bitmap may include at least one bit. For example, the number of bits in the bitmap is the same as the number of time domain units in the at least one time domain unit. For example, if the at least one time domain unit is n time domain units, the bitmap may include n bits, where the i-th bit is used to indicate whether a subband is configured for the i-th time domain unit, where 1≤i≤n. For example, a bit of 1 may indicate that a subband is configured, and a bit of 0 may indicate that a subband is not configured.

[0314] For example, as shown in Figure 4, at least one time domain unit includes 10 time slots, and the bitmap can be 11110000000000. Based on the bitmap, the terminal can determine that the first four time slots (slot #0 to slot #3) of the 10 time slots are configured with uplink subbands. Based on this, the first information can also include a resource indication value, where the resource indication value is used to indicate the time domain resources of the uplink subbands in slot #0 to slot #3.

[0315] In some embodiments, the first information includes a bitmap, and the bitmap is used for at least one of the following:

[0316] used to determine that the time domain resources of the subband in each time domain unit in at least one time domain unit are all time domain resources in the time domain unit where the subband is located, wherein each bit in the bitmap indicates a first value;

[0317] The method is used to determine that no subband is configured in each time domain unit in at least one time domain unit, wherein each bit in the bitmap indicates a second value. The first value and the second value may be different values.

[0318] In some embodiments, the first information may only include a bitmap instead of a resource indication value. Accordingly, a bitmap can be used to indicate the time domain resources of the subband in each time domain unit in at least one time domain unit. The first information contains less information, which is conducive to saving communication resources.

[0319] In some embodiments, a bitmap is used to determine that the time domain resources of a subband in each time domain unit in at least one time domain unit are all time domain resources in the time domain unit where the subband is located, wherein each bit in the bitmap indicates a first value.

[0320] In some embodiments, the network device may set the position of each bit in the bitmap to a first value. After receiving the first indication information, the terminal may determine that each bit in the bitmap indicates the first value and determine that the time domain resources of the subband in each time domain unit in at least one time domain unit are all the time domain resources in the time domain unit in which the subband is located. Accordingly, the time domain resources of the subband in each time domain unit in at least one time domain unit can be indicated by a single bitmap, which is beneficial for saving communication resources.

[0321] For example, at least one time domain unit is 10 time slots, the first value can be 1, and when the terminal determines that the bitmap in the first information is 1111111111, it can further determine that the time domain resources of the subband in each of the 10 time slots are all symbols in the time slot.

[0322] In some embodiments, a bitmap is used to determine that no subband is configured in each time domain unit in the at least one time domain unit, wherein each bit in the bitmap indicates the second value.

[0323] In some embodiments, the network device may set the position of each bit in the bitmap to a second value. After the terminal receives the first indication information, when it is determined that each bit in the bitmap indicates the second value, it can be determined that no subband is configured in each time domain unit in at least one time domain unit.

[0324] For example, at least one time domain unit is 10 time slots, and the second value may be 0. When the terminal determines that the bitmap in the first information is 0000000000, it may further determine that no subband is configured in each of the 10 time slots.
