For example, step S201 may be implemented as an independent embodiment, and step S202 may be implemented as an independent embodiment, but the present invention is not limited thereto.
[0133] In some embodiments, steps S201 and S202 may be performed in an interchangeable order or simultaneously.

[0137] In a first aspect, 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.
[0138] As shown in FIG3 , the resource determination method may include the following steps:
[0139] In step S301, downlink control information (DCI) sent by a network device is received;
[0140] In step S302, subband resources are determined according to downlink control information.
[0141] 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.
[0142] According to embodiments of the present disclosure, a network device can send downlink control information to a terminal, and the terminal can receive the downlink control information sent by the network device and determine subband resources based on the downlink control information. Because the downlink control information is dynamic signaling, subband resources can be dynamically configured for the terminal based on the downlink control information. This facilitates flexible allocation of subband resources required for communication to the terminal based on dynamic information such as service status and interference status, thereby ensuring effective subband-based communication between the network device and the terminal.
[0143] In some embodiments, the subband may include at least one of the following: an uplink subband (UL subband) and a downlink subband (DL subband), wherein UL stands for Uplink and DL stands for Downlink.
[0144] In some embodiments, the resources of the sub-band may include at least one of the following: frequency domain resources of the sub-band, and time domain resources of the sub-band.
[0145] In some embodiments, the downlink control information includes at least one of the following:
[0146] Group common downlink control information (group common DCI);
[0147] Downlink control information dedicated to indicating subband resources.
[0148] In some embodiments, the group common downlink control information includes: DCI format 2_0.
[0149] For example, the network device may send group common downlink control information to each terminal in the terminal group in a broadcast or multicast manner, and each terminal in the terminal group may determine subband resources according to the group common downlink control information.
[0150] In some embodiments, the downlink control information satisfies at least one of the following:
[0151] Scrambling by Slot Format Indicator Radio Network Temporary Identifier (SFI-RNTI);
[0152] In the Type-3 SS (Search Space).
[0153] In which, when the downlink control information is downlink control information dedicated to indicating subband resources, the downlink control information dedicated to indicating subband resources can be scrambled by a radio network temporary identifier related to the subband. For example, the radio network temporary identifier can be a newly defined radio network temporary identifier, for example, it can be called a subband slot format indication radio network temporary identifier (Subband SFI-RNTI).
[0154] For example, the downlink control information dedicated to indicating the resources of the subband may be newly defined downlink control information. For example, the format of the downlink control information may be different from the format of legacy downlink control information.
[0155] In some embodiments, the downlink control information includes a first information field, and the first information field is used to indicate resources of a subband.
[0156] The downlink control information may include at least one information field (also referred to as a field), wherein a first information field may be used to indicate subband resources. The first information field may reuse a conventional information field (for example, one or more reserved bits in conventional information may be used as the first information field) or may be a newly defined information field, which is not limited in this disclosure.
[0157] In some embodiments, the downlink control information includes group common downlink control information, and the group common downlink control information further includes at least one of the following information fields:
[0158] Slot Format Indicator (SFI) information field;
[0159] Channel Occupancy Time Indication (COT indication) information field;
[0160] Search space switching indication information field.
[0161] For example, if the line control information includes DCI format 2_0, DCI format 2_0 may include a first information field, where the first information field may include at least one of the following:
[0162] An information field used to indicate subband time domain resources (e.g., Subband time indication);
[0163] An information field used to indicate subband frequency domain resources (e.g., Subband frequency indication);
[0164] On this basis, DCI format 2_0 may further include, for example, a time slot format indication information field, for example, a channel occupancy time indication information field, for example, a search space switching indication information field, for example, a time slot format indication information field and a channel occupancy time indication information field, for example, a time slot format indication information field and a search space switching indication information field, for example, a channel occupancy time indication information field and a search space switching indication information field, for example, a time slot format indication information field, a channel occupancy time indication information field and a search space switching indication information field.
[0165] The position of the first information field in the downlink control information can be located after the above three information fields, before the above three information fields, or between any two of the above three information fields, which is not limited by the present disclosure.
[0166] It should be noted that, in addition to including the first information field, the downlink control information may also include information fields not limited to the above three, and may also include other information fields, which is not limited in the present disclosure.
[0167] In some embodiments, the position of the first information field in the downlink control information is determined based on radio resource control (RRC) signaling. The terminal can determine the starting position of the first information field in the received downlink control information based on the RRC signaling to accurately determine the information indicated by the first information field.
[0168] The radio resource control signaling may also indicate the size of the first information field in the downlink control information (e.g., the number of bits occupied). In some embodiments, the starting position, size, and other information of the first information field in the downlink control information are not limited to those indicated by the radio resource control signaling, but may also be agreed upon by the protocol. In some embodiments, part of the above-mentioned starting position, size, and other information may be agreed upon by the protocol, and the other part may be indicated by the radio resource control signaling.
[0169] In some embodiments, the downlink control information may indicate to the terminal the resources of subbands in one or more carriers (a carrier may correspond to a cell, and thus may also be written as a cell here).
[0170] Take the example where the downlink control information includes multiple indication information, each of which is used to indicate subband resources on multiple carriers.
[0171] For example, the downlink control information includes indication information #1 and indication information #2, wherein indication information #1 is used to indicate subband resources on carrier #1, and indication information #2 is used to indicate subband resources on carrier #2.
[0172] In some embodiments, the resources of the sub-band are resources within the first time window.
[0173] In some embodiments, the first time window is determined according to at least one of the following:
[0174] Indicative information for network devices;
[0175] Information in downlink control information;
[0176] Detection period of downlink control information.
[0177] For example, the network device can indicate the sub-band resources within the first time window to the terminal through downlink control information. The terminal can communicate with the network device based on the sub-band resources within the first time window, and stop communicating with the network device based on the sub-band resources outside the first time window.
[0178] The first time window may be indicated by the network device through indication information, or may be indicated by the network device through information in the downlink control information, or may be determined based on a monitoring period of the downlink control information. For example, the monitoring period of the downlink control information may be related to a period of a search space in which the downlink control information is located (for example, equal to the period of the search space). The search space in the embodiments of the present disclosure may be a common search space (CSS) or a terminal-specific search space (USS), which is not limited in the present disclosure.
[0179] In some embodiments, the resource determination method further comprises: determining a set of configuration information of resources of a subband according to radio resource control signaling;
[0180] The determining of the sub-band resources according to the downlink control information includes: determining the sub-band resources according to configuration information corresponding to the downlink control information in the set.
[0181] In some embodiments, a network device may indicate a set of subband resource configuration information to a terminal via radio resource control signaling, wherein the set may be represented in the form of a list or other form, which is not limited by the present disclosure. Furthermore, the network device may indicate a piece of configuration information in the above set via downlink control information (e.g., an uplink grant (UL grant) information field or a downlink assignment (DL assignment) information field in the downlink control information) for the terminal to determine the subband resource.
[0182] Correspondingly, the terminal may first determine a set of configuration information of sub-band resources according to radio resource control signaling, then determine configuration information one by one in the set according to downlink control information, and determine the sub-band resources according to the configuration information.
[0183] For example, a subband includes an uplink subband. The network device configures uplink subband candidates (UL subband candidates) for the terminal through radio resource control signaling. The radio resource control signaling configures M uplink subband candidates for the terminal. Different uplink subband candidates have different resource configuration information. The length of the uplink subband indication (UL subband indication) carried in the downlink control information can be log2(M) bits. For example, Table 1 below shows the association between the uplink subband indication and the uplink subband configuration index.
[0184] Table 1
[0185] As shown in Table 1, when M = 2, the uplink subband indication occupies 2 bits, and can thus indicate four situations: 00, 01, 10, and 11. The uplink subband configuration index (UL subband configuration index) can correspond one-to-one with the configuration information in the set. The terminal can determine the corresponding uplink subband configuration index based on the downlink subband indication in the downlink control information, and further determine the corresponding configuration information based on the uplink subband configuration index, and then determine the uplink subband resources based on the configuration information.
[0186] In some embodiments, the configuration information of the set may include an empty configuration. When the configuration information determined by the terminal in the set according to the downlink control information is an empty configuration, the terminal may determine that no subband exists in the first time window.
[0187] It should be noted that the configuration information of the sub-band resources can be entirely included in the wireless resource control signaling, or partially included in the wireless resource control signaling and partially included in the downlink control information. For example, one of the time domain resource configuration information and the frequency domain resource configuration information is included in the wireless resource control signaling, and the other is included in the downlink control information. This disclosure does not limit this.
[0188] In some embodiments, determining subband resources according to downlink control information includes:
[0189] Determining subband resources according to radio resource control signaling;
[0190] The time domain unit where the subband exists is determined according to the time slot format indication information field in the downlink control information.
[0191] In some embodiments, the network device can, on the one hand, configure sub-band resources for the terminal through wireless resource control signaling, and on the other hand, indicate to the terminal the transmission direction corresponding to the time domain unit (for example, uplink, downlink, flexible) through the time slot format indication information field in the downlink control information. The terminal can determine the time domain unit where the sub-band of resources indicated in the wireless resource control signaling is located based on the time slot format indication information field.
[0192] In some embodiments, determining the time domain unit in which the subband exists according to the time slot format indication information field in the downlink control information includes at least one of the following:
[0193] The transmission direction corresponding to the first time domain unit indicated by the time slot structure information field is the same as the transmission direction corresponding to the subband, and it is determined that the subband exists on the first time domain unit;
[0194] The transmission direction corresponding to the first time domain unit indicated by the time slot structure information field is opposite to the transmission direction corresponding to the subband, and it is determined that the subband does not exist in the first time domain unit;
[0195] The first time domain unit indicated by the time slot structure information field is a flexible time domain unit, and it is determined that a subband exists on the first time domain unit;
[0196] The first time domain unit indicated by the time slot structure information field is a flexible time domain unit, and it is determined that no subband exists on the first time domain unit.
[0197] It should be noted that the logic for determining the time domain unit in which the subband exists according to the time slot format indication information field in the downlink control information is not limited to the above, and may also include, for example, at least one of the following:
[0198] The transmission direction corresponding to the first time domain unit indicated by the time slot structure information field is the same as the transmission direction corresponding to the subband, and it is determined that no subband exists on the first time domain unit;
[0199] The transmission direction corresponding to the first time domain unit indicated by the time slot structure information field is opposite to the transmission direction corresponding to the sub-band, and it is determined that the sub-band exists on the first time domain unit.
[0200] In some embodiments, the downlink control information may indicate to the terminal the subband resources in one or more carriers. For multiple carriers, the logic of determining the time domain unit in which the subband exists based on the time slot format indication information field in the downlink control information may be determined for each carrier.
[0201] For example, the terminal may determine, based on instructions from the network device, on which carrier or carriers to determine the time domain units containing subbands based on the time slot format indication information field in the downlink control information. Taking carrier #1 and carrier #2 as an example, based on instructions from the network device, the terminal may determine, based on instructions from the network device, that the time domain units containing subbands on carrier #1 are determined based on the time slot format indication information field in the downlink control information, while not determining the time domain units containing subbands on carrier #2 based on the time slot format indication information field in the downlink control information.
[0202] For example, based on the subband configuration on the carrier, the terminal can determine on which carrier or carriers the time domain units containing the subbands are determined based on the time slot format indication information field in the downlink control information. Taking carrier #1 and carrier #2 as an example, the terminal can first determine the subband configuration on carrier #1 and carrier #2. If it is determined that subbands are configured on carrier #1 and not on carrier #2, the terminal can determine on carrier #1 the time domain units containing the subbands based on the time slot format indication information field in the downlink control information, while not determining on carrier #2 the time domain units containing the subbands based on the time slot format indication information field in the downlink control information.
[0203] In some embodiments, the terminals in the embodiments of the present disclosure may be full-duplex capable terminals or half-duplex capable terminals, and the present disclosure is not limiting. The network device may configure sub-bands for one or more terminals in a time-division duplex (TDD) frequency band and perform full-duplex communication on the time domain units configured with the sub-bands.
[0204] For example, a network device may configure an uplink subband on a downlink time domain unit or a flexible time domain unit. The network device may then perform uplink communications in the uplink subband and perform downlink communications on frequency domain resources other than the uplink subband corresponding to the downlink time domain unit or the flexible time domain unit. The downlink time domain unit or the flexible time domain unit may be semi-static or determined based on the slot format indication information field in the downlink control information.
[0205] For example, a network device may configure an uplink subband under an uplink time domain unit or a flexible time domain unit. The network device may then perform downlink communications in the downlink subband and perform uplink communications on frequency domain resources other than the downlink subband corresponding to the uplink time domain unit or the flexible time domain unit. The uplink time domain unit or the flexible time domain unit may be semi-static or determined based on the time slot format indication information field in the downlink control information.
[0206] Among them, the semi-static uplink time domain unit, downlink time domain unit, and flexible time domain unit can be configured to the terminal by the network device through the time division duplex uplink and downlink common configuration (tdd-UL-DL-ConfigurationCommon), or through the time division duplex uplink and downlink common configuration and the time division duplex uplink and downlink dedicated configuration (tdd-UL-DL-ConfigurationDedicated). The time domain unit includes at least one of the following: frame, subframe, time slot (slot), symbol (symbol), wherein the symbol can be an OFDM (Orthogonal Frequency Division Multiplexing, orthogonal frequency division multiplexing) symbol.
[0207] 4A and 4B are schematic diagrams showing application scenarios of a resource determination method according to an embodiment of the present disclosure.
[0208] As shown in Figure 4A, taking the time domain unit including time slots as an example, the network device configures a semi-static time slot structure of DDFFU for the terminal for the five time slots slot#0 to slot#4, where D indicates that the transmission direction corresponding to the time slot is downlink, U indicates that the transmission direction corresponding to the time slot is uplink, and F indicates that the transmission direction corresponding to the time slot is flexible, that is, the transmission direction corresponding to slot#0 to slot#1 is downlink, the transmission direction corresponding to slot#2 to slot#3 is flexible, and the transmission direction corresponding to slot#4 is uplink.
[0209] Since the DDFFU time slot structure shown in Figure 4A is a semi-static time slot structure, the network device can dynamically adjust the time slot structure through the time slot format in the downlink control information. For example, as shown in Figure 4B, the network device indicates the transmission direction of slot#2 in the above five time slots as uplink and the transmission direction of slot#3 as downlink through the time slot format indication information field in the downlink control information.
[0210] The network device also indicates the subband resources through radio resource control signaling, including the uplink subband resources on the above slot#2 and slot#3 (time domain resources include the 3rd to 4th time slots, and frequency domain resources are not limited in this disclosure).
[0211] For example, determining a time domain unit in which a subband exists according to the time slot format indication information field in the downlink control information includes: the transmission direction corresponding to the first time domain unit indicated by the time slot structure information field is the same as the transmission direction corresponding to the subband, and determining that a subband exists on the first time domain unit; and the transmission direction corresponding to the first time domain unit indicated by the time slot structure information field is opposite to the transmission direction corresponding to the subband, and determining that no subband exists on the first time domain unit.
[0212] Since the transmission direction for the subband is uplink, and the slot structure indication information field indicates the transmission direction for slot #2 as uplink, which is the same as the transmission direction for the subband, it can be determined that uplink subband resources configured by radio resource control signaling exist in slot #2. However, the transmission direction for slot #3 is also downlink, which is opposite to the transmission direction for the subband, so it can be determined that uplink subband resources configured by radio resource control signaling do not exist in slot #3. The terminal is in slot #2 and can conduct uplink communication with the network device in the uplink subband.
[0213] Based on this, the network device only needs to configure the sub-band resources for the terminal in the wireless resource control signaling, and the terminal can determine which specific sub-band is configured on which time domain units based on the transmission direction of the sub-band and the transmission direction indicated by the time slot structure indication information field in the downlink control information. Accordingly, the network device does not need to indicate the sub-band resources for each time domain unit separately, which is conducive to saving the overhead of the network device to configure sub-band resources for the terminal.
[0214] In a second aspect, embodiments of the present disclosure provide a resource determination method. Figure 5 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 network device.
[0215] As shown in FIG5 , the resource determination method may include the following steps:
[0216] In step S501, downlink control information is sent to a terminal, wherein the downlink control information is used by the terminal to determine subband resources.
[0217] According to embodiments of the present disclosure, a network device can send downlink control information to a terminal, and the terminal can receive the downlink control information sent by the network device and determine subband resources based on the downlink control information. Because the downlink control information is dynamic signaling, subband resources can be dynamically configured for the terminal based on the downlink control information. This facilitates flexible allocation of subband resources required for communication to the terminal based on dynamic information such as service status and interference status, thereby ensuring effective subband-based communication between the network device and the terminal.
[0218] In some embodiments, the subband may include at least one of the following: an uplink subband (UL subband) and a downlink subband (DL subband).
[0219] In some embodiments, the resources of the sub-band may include at least one of the following: frequency domain resources of the sub-band, and time domain resources of the sub-band.
[0220] In some embodiments, the downlink control information includes at least one of the following:
[0221] Group public downlink control information;
[0222] Downlink control information dedicated to indicating subband resources.
[0223] In some embodiments, the group common downlink control information includes: DCI format 2_0.
[0224] For example, the network device may send group common downlink control information to each terminal in the terminal group in a broadcast or multicast manner, and each terminal in the terminal group may determine subband resources according to the group common downlink control information.
[0225] In some embodiments, the downlink control information satisfies at least one of the following:
[0226] Scrambling via Slot Format Indicator Radio Network Temporary Identity (SFI-RNTI);
[0227] In the Type-3 common search space (Type-3SS).
[0228] In which, when the downlink control information is downlink control information dedicated to indicating subband resources, the downlink control information dedicated to indicating subband resources can be scrambled by a radio network temporary identifier related to the subband. For example, the radio network temporary identifier can be a newly defined radio network temporary identifier, for example, it can be called a subband slot format indication radio network temporary identifier (Subband SFI-RNTI).
[0229] For example, the downlink control information dedicated to indicating the resources of the subband may be newly defined downlink control information. For example, the format of the downlink control information may be different from the format of legacy downlink control information.
[0230] In some embodiments, the downlink control information includes a first information field, and the first information field is used to indicate resources of a subband.
[0231] The downlink control information may include at least one information field (also referred to as a field), wherein a first information field may be used to indicate subband resources. The first information field may reuse a conventional information field (for example, one or more reserved bits in conventional information may be used as the first information field) or may be a newly defined information field, which is not limited in this disclosure.
[0232] In some embodiments, the downlink control information includes group common downlink control information, and the group common downlink control information further includes at least one of the following information fields:
[0233] Slot Format Indicator (SFI) information field;
[0234] Channel Occupancy Time Indication (COT indication) information field;
[0235] Search space switching indication information field.
[0236] For example, if the line control information includes DCI format 2_0, DCI format 2_0 may include a first information field, where the first information field may include at least one of the following:
[0237] An information field used to indicate subband time domain resources (e.g., Subband time indication);
[0238] An information field used to indicate subband frequency domain resources (e.g., Subband frequency indication);
[0239] On this basis, DCI format 2_0 may further include, for example, a time slot format indication information field, for example, a channel occupancy time indication information field, for example, a search space switching indication information field, for example, a time slot format indication information field and a channel occupancy time indication information field, for example, a time slot format indication information field and a search space switching indication information field, for example, a channel occupancy time indication information field and a search space switching indication information field, for example, a time slot format indication information field, a channel occupancy time indication information field and a search space switching indication information field.
[0240] The position of the first information field in the downlink control information can be located after the above three information fields, before the above three information fields, or between any two of the above three information fields, which is not limited by the present disclosure.
[0241] It should be noted that, in addition to including the first information field, the downlink control information may also include information fields not limited to the above three, and may also include other information fields, which is not limited in the present disclosure.
[0242] In some embodiments, the position of the first information field in the downlink control information is determined based on radio resource control (RRC) signaling. The terminal can determine the starting position of the first information field in the received downlink control information based on the radio resource control signaling to accurately determine the information indicated by the first information field.
[0243] The radio resource control signaling may also indicate the size of the first information field in the downlink control information (e.g., the number of bits occupied). In some embodiments, the starting position, size, and other information of the first information field in the downlink control information are not limited to those indicated by the radio resource control signaling, but may also be agreed upon by the protocol. In some embodiments, part of the above-mentioned starting position, size, and other information may be agreed upon by the protocol, and the other part may be indicated by the radio resource control signaling.
[0244] In some embodiments, the downlink control information may indicate to the terminal the resources of subbands in one or more carriers (a carrier may correspond to a cell, and thus may also be written as a cell here).
[0245] Take the example where the downlink control information includes multiple indication information, each of which is used to indicate subband resources on multiple carriers.
[0246] For example, the downlink control information includes indication information #1 and indication information #2, wherein indication information #1 is used to indicate subband resources on carrier #1, and indication information #2 is used to indicate subband resources on carrier #2.
[0247] In some embodiments, the resources of the sub-band are resources within the first time window.
[0248] In some embodiments, the first time window is determined according to at least one of the following:
[0249] Indicative information for network devices;
[0250] Information in downlink control information;
[0251] Detection period of downlink control information.
[0252] For example, the network device can indicate the sub-band resources within the first time window to the terminal through downlink control information. The terminal can communicate with the network device based on the sub-band resources within the first time window, and stop communicating with the network device based on the sub-band resources outside the first time window.
[0253] The first time window may be indicated by the network device through indication information, or may be indicated by the network device through information in the downlink control information, or may be determined based on a monitoring period of the downlink control information. For example, the monitoring period of the downlink control information may be related to a period of the search space in which the downlink control information is located (e.g., equal to the period of the search space). The search space in the embodiments of the present disclosure may be a common search space (CSS) or a terminal-specific search space (USS), and the present disclosure is not limited thereto.
[0254] In some embodiments, the resource determination method further includes: sending wireless resource control signaling to the terminal, wherein the wireless resource control signaling is used by the terminal to determine a set of configuration information of subband resources, and the downlink control information is used by the terminal to determine the configuration information of subband resources in the set.
[0255] In some embodiments, a network device may indicate a set of subband resource configuration information to a terminal via radio resource control signaling, wherein the set may be represented in the form of a list or other form, which is not limited by the present disclosure. Furthermore, the network device may indicate a piece of configuration information in the above set via downlink control information (e.g., an uplink grant (UL grant) information field or a downlink assignment (DL assignment) information field in the downlink control information) for the terminal to determine the subband resource.
[0256] Correspondingly, the terminal may first determine a set of configuration information of sub-band resources according to radio resource control signaling, then determine configuration information one by one in the set according to downlink control information, and determine the sub-band resources according to the configuration information.
[0257] For example, a subband includes an uplink subband. The network device configures uplink subband candidates (UL subband candidates) for the terminal through radio resource control signaling. The radio resource control signaling configures M uplink subband candidates for the terminal. Different uplink subband candidates have different resource configuration information. The length of the uplink subband indication (UL subband indication) carried in the downlink control information can be log2(M) bits. For example, Table 1 above shows the association between the uplink subband indication and the uplink subband configuration index.
[0258] As shown in Table 1, when M = 2, the uplink subband indication occupies 2 bits, and can thus indicate four situations: 00, 01, 10, and 11. The uplink subband configuration index (UL subband configuration index) can correspond one-to-one with the configuration information in the set. The network device can indicate the corresponding uplink subband configuration index to the terminal through the downlink subband indication in the downlink control information. The terminal can then determine the corresponding configuration information based on the uplink subband configuration index and determine the uplink subband resources based on the configuration information.
[0259] In some embodiments, the configuration information of the set may include an empty configuration. When the configuration information determined by the terminal in the set according to the downlink control information is an empty configuration, the terminal may determine that no subband exists in the first time window.
[0260] It should be noted that the configuration information of the sub-band resources can be entirely included in the wireless resource control signaling, or partially included in the wireless resource control signaling and partially included in the downlink control information. For example, one of the time domain resource configuration information and the frequency domain resource configuration information is included in the wireless resource control signaling, and the other is included in the downlink control information. This disclosure does not limit this.
[0261] In some embodiments, the resource determination method further includes: sending wireless resource control signaling to the terminal, wherein the wireless resource control signaling is used by the terminal to determine the resources of the subband, and the time slot format indication information field in the downlink control information is used by the terminal to determine the time domain unit where the subband exists.
[0262] In some embodiments, the network device can, on the one hand, configure sub-band resources for the terminal through wireless resource control signaling, and on the other hand, indicate to the terminal the transmission direction corresponding to the time domain unit (for example, uplink, downlink, flexible) through the time slot format indication information field in the downlink control information. The terminal can determine the time domain unit where the sub-band of resources indicated in the wireless resource control signaling is located based on the time slot format indication information field.
[0263] In some embodiments, the time slot format indication information field in the downlink control information is used by the terminal to determine the time domain unit in which the subband exists, and includes at least one of the following:
[0264] The transmission direction corresponding to the first time domain unit indicated by the time slot structure information field is the same as the transmission direction corresponding to the subband, and the time slot structure information field is used by the terminal to determine whether the subband exists on the first time domain unit;
[0265] The transmission direction corresponding to the first time domain unit indicated by the time slot structure information field is opposite to the transmission direction corresponding to the subband, and the time slot structure information field is used by the terminal to determine that no subband exists on the first time domain unit;
[0266] The first time domain unit indicated by the time slot structure information field is a flexible time domain unit, and the time slot structure information field is used by the terminal to determine whether a subband exists in the first time domain unit;
[0267] The first time domain unit indicated by the time slot structure information field is a flexible time domain unit, and the time slot structure information field is used by the terminal to determine whether a subband does not exist on the first time domain unit.
[0268] It should be noted that the time slot format indication information field in the downlink control information is used by the terminal to determine the logic of the time domain unit in which the subband exists, and is not limited to the above types. For example, it may also include at least one of the following:
[0269] The transmission direction corresponding to the first time domain unit indicated by the time slot structure information field is the same as the transmission direction corresponding to the subband, and it is determined that no subband exists on the first time domain unit;
[0270] The transmission direction corresponding to the first time domain unit indicated by the time slot structure information field is opposite to the transmission direction corresponding to the sub-band, and it is determined that the sub-band exists on the first time domain unit.
[0271] In some embodiments, the downlink control information may indicate to the terminal the subband resources in one or more carriers. For multiple carriers, the logic of determining the time domain unit in which the subband exists based on the time slot format indication information field in the downlink control information may be determined for each carrier.
[0272] For example, the network device may instruct the terminal to determine on which carrier or carriers the subband time domain units are present based on the slot format indication information field in the downlink control information. Taking carrier #1 and carrier #2 as an example, the terminal, based on the network device's instruction, may determine on carrier #1 the subband time domain units are present based on the slot format indication information field in the downlink control information, while not determining on carrier #2 the subband time domain units are present based on the slot format indication information field in the downlink control information.
[0273] For example, based on the subband configuration on the carrier, the terminal can determine on which carrier or carriers the time domain units containing the subbands are determined based on the time slot format indication information field in the downlink control information. Taking carrier #1 and carrier #2 as an example, the terminal can first determine the subband configuration on carrier #1 and carrier #2. If it is determined that subbands are configured on carrier #1 and not on carrier #2, the terminal can determine on carrier #1 the time domain units containing the subbands based on the time slot format indication information field in the downlink control information, while not determining on carrier #2 the time domain units containing the subbands based on the time slot format indication information field in the downlink control information.
[0274] In some embodiments, the terminals in the embodiments of the present disclosure may be full-duplex capable terminals or half-duplex capable terminals, and the present disclosure is not limiting. The network device may configure sub-bands for one or more terminals in a time division duplex (TDD) frequency band and perform full-duplex communication on the time domain units configured with the sub-bands.
[0275] For example, a network device may configure an uplink subband on a downlink time domain unit or a flexible time domain unit. The network device may then perform uplink communications in the uplink subband and perform downlink communications on frequency domain resources other than the uplink subband corresponding to the downlink time domain unit or the flexible time domain unit. The downlink time domain unit or the flexible time domain unit may be semi-static or determined based on the slot format indication information field in the downlink control information.
[0276] For example, a network device may configure an uplink subband under an uplink time domain unit or a flexible time domain unit. The network device may then perform downlink communications in the downlink subband and perform uplink communications on frequency domain resources other than the downlink subband corresponding to the uplink time domain unit or the flexible time domain unit. The uplink time domain unit or the flexible time domain unit may be semi-static or determined based on the time slot format indication information field in the downlink control information.
[0277] Among them, the semi-static uplink time domain unit, downlink time domain unit, and flexible time domain unit can be configured to the terminal by the network device through the time division duplex uplink and downlink common configuration (tdd-UL-DL-ConfigurationCommon), or through the time division duplex uplink and downlink common configuration and time division duplex uplink and downlink dedicated configuration (tdd-UL-DL-ConfigurationDedicated). The time domain unit includes at least one of the following: frame, subframe, time slot (slot), symbol (symbol), where the symbol can be an OFDM symbol.
[0278] As shown in Figure 4A, taking the time domain unit including time slots as an example, the network device configures a semi-static time slot structure of DDFFU for the terminal for 5 time slots, wherein D indicates that the transmission direction corresponding to the time slot is downlink, U indicates that the transmission direction corresponding to the time slot is uplink, and F indicates that the transmission direction corresponding to the time slot is flexible, that is, the transmission direction corresponding to the 1st to 2nd time slots is downlink, the transmission direction corresponding to the 3rd to 4th time slots is flexible, and the transmission direction corresponding to the 5th time slot is uplink.
[0279] Since the DDFFU time slot structure shown in Figure 4A is a semi-static time slot structure, the network device can dynamically adjust the time slot structure through the time slot format in the downlink control information. For example, as shown in Figure 4B, the network device indicates the transmission direction of the third time slot of the above five time slots as uplink and the transmission direction of the fourth time slot as downlink through the time slot format indication information field in the downlink control information.
[0280] The network device also indicates the subband resources through radio resource control signaling, including the uplink subband resources on the above-mentioned 3rd and 4th time slots (time domain resources include the 3rd to 4th time slots, and frequency domain resources are not limited in this disclosure).
[0281] For example, determining a time domain unit in which a subband exists according to the time slot format indication information field in the downlink control information includes: the transmission direction corresponding to the first time domain unit indicated by the time slot structure information field is the same as the transmission direction corresponding to the subband, and determining that a subband exists on the first time domain unit; and the transmission direction corresponding to the first time domain unit indicated by the time slot structure information field is opposite to the transmission direction corresponding to the subband, and determining that no subband exists on the first time domain unit.
[0282] Since the transmission direction corresponding to the subband is uplink, and the slot structure indication information field indicates the transmission direction for the third time slot is also uplink, which is the same as the transmission direction corresponding to the subband, it can be determined that the uplink subband resources configured by the radio resource control signaling exist in the third time slot. However, the transmission direction indicated by the slot structure indication information field for the fourth time slot is also downlink, which is opposite to the transmission direction corresponding to the subband. Therefore, it can be determined that the uplink subband resources configured by the radio resource control signaling do not exist in the third time slot. In the third time slot, the terminal can conduct uplink communication with the network device in the uplink subband.
[0283] Based on this, the network device only needs to configure the sub-band resources for the terminal in the wireless resource control signaling, and the terminal can determine which specific sub-band is configured on which time domain units based on the transmission direction of the sub-band and the transmission direction indicated by the time slot structure indication information field in the downlink control information. Accordingly, the network device does not need to indicate the sub-band resources for each time domain unit separately, which is conducive to saving the overhead of the network device to configure sub-band resources for the terminal.
