Instead, it is used to transmit scrambled information of the Slot Format Indication (Radio Network Temporary Identity) (SFI-RNTI) within the Type-3 Common Search Space (CSS).
[0159] In the Rel-18 duplex phase, semi-static subband full duplex (semi-static SBFD) was established as a fundamental research topic. This means that the subbands used for SBFD operations are semi-statically configured via Radio Resource Control (RRC) signaling.
[0160] In order to improve the flexibility of subband configuration, the present disclosure provides a method and apparatus for determining resources, and a storage medium.
[0161] FIG2 is an interactive diagram of a method for determining resources according to an embodiment of the present disclosure. As shown in FIG2 , an embodiment of the present disclosure relates to a method for determining resources, and the method includes:
[0162] Step S2101 : The network device 102 sends pre-configuration information to the terminal 101 .
[0163] In some embodiments, terminal 101 receives the pre-configuration information.
[0164] In some embodiments, the pre-configuration information is used to pre-configure sub-band resources for terminal 101 .
[0165] In some embodiments, the network device 102 may send the pre-configuration information via second signaling.
[0166] In one example, the second signaling may be RRC signaling.
[0167] In one example, the second signaling may be a system message. Exemplarily, the second signaling may be a system information block n (System Information Block n, SIBn), where n is a positive integer.
[0168] For example, if n is 1, the network device 102 may send the pre-configuration information to the terminal 101 via SIB1.
[0169] In some embodiments, the pre-configuration information may include but is not limited to at least one of the following: subband indication information, the subband indication information is used to indicate whether the subband exists; candidate time domain resource indication information of the subband, the candidate time domain resource indication information is used to indicate the candidate time domain resources occupied by the subband; candidate frequency domain resource indication information of the subband, the candidate frequency domain resource indication information is used to indicate the candidate frequency domain resources occupied by the subband; candidate time window indication information, the time window indication information is used to indicate the candidate time window; and an index of the subband resource candidate configuration.
[0170] The subband indication information may indicate whether a subband exists using 1 bit. For example, a bit value of "1" indicates the existence of a subband, and a bit value of "0" indicates the absence of a subband, and vice versa.
[0171] Alternatively, the subband indication information may be set to "true" or "false" to indicate whether a subband exists.
[0172] The present disclosure does not limit the indication method of the sub-band indication information.
[0173] The candidate time domain resource indication information for the subband can be used to pre-configure candidate time domain resources that can be occupied by the subband for terminal 101. It is understood that there can be one or more groups of time domain resources, and each group of time domain resources can be in units of time slots, orthogonal frequency division multiplexing symbols (OFDM symbols), durations, etc., which are not limited in this disclosure. The duration includes one or more consecutive OFDM symbols within the same time slot.
[0174] For example, the candidate time domain resource indication information of the subband indicates: candidate time domain resource #1 {symbol#0 on slot#0, symbol#1 on slot#0}, candidate time domain resource #2 {slot#1, slot#2}...
[0175] The candidate frequency domain resource indication information of the subband can be used to pre-configure the candidate frequency domain resources that can be occupied by the subband for the terminal 101. It is understood that there can be one or more groups of frequency domain resources, and each group of frequency domain resources can be in the form of resource blocks (RBs) or resource block groups (RBGs), which is not limited in this disclosure.
[0176] For example, the candidate frequency domain resource indication information of the subband indicates: candidate frequency domain resource #1 {RBG#0, RBG#1}, candidate frequency domain resource #2 {RBG#2, RBG#3}...
[0177] The candidate time window is the time domain range in which the candidate subband resource configuration takes effect. Each candidate time window may correspond to a group of candidate time domain resources and / or a group of candidate frequency domain resources.
[0178] For example, candidate time window #1 corresponds to the candidate time domain resource #1 and the candidate frequency domain resource #2. Then, within the candidate time window #1, the subband resource candidate configuration takes effect, and the subband resource candidate configuration includes the candidate time domain resource #1 and the candidate frequency domain resource #2.
[0179] The index of the subband resource candidate configuration may be used to indicate a combination of one or more of subband indication information, a group of candidate time domain resources, a group of candidate frequency domain resources, and a candidate time window.
[0180] For example, index #0 is used to indicate subband indication information #1, and subband indication information #1 is used to indicate that a subband does not exist.
[0181] For another example, index #1 is used to indicate subband indication information #2, candidate time window #1, candidate time domain resource #1, and candidate frequency domain resource #2, wherein subband indication information #2 is used to indicate the existence of a subband.
[0182] For example, index #2 is used to indicate candidate time window #2, which corresponds to candidate time domain resource #2 and candidate frequency domain resource #4. Index #2 is equivalent to indicating the existence of a subband and indicating a set of candidate time domain resources, a set of candidate frequency domain resources, and a candidate time window for the subband.
[0183] The above description is merely an exemplary description, and the present disclosure does not limit the candidate subband resource configuration corresponding to the index.
[0184] Step S2102 , the network device 102 sends a first signaling to the terminal 101 .
[0185] In some embodiments, terminal 101 receives the first signaling.
[0186] In some embodiments, the first signaling may be UE-specific signaling.
[0187] In some embodiments, the first signaling carries sub-band resource indication information, wherein the sub-band resources include but are not limited to sub-band time domain resources and / or sub-band frequency domain resources.
[0188] In some embodiments, the first signaling may be unicast DCI.
[0189] In some embodiments, the sub-band resource indication information may be carried in the sub-band resource indication information field of the unicast DCI.
[0190] In some embodiments, the terminal 101 may receive the unicast DCI sent by the network device in a terminal-specific search space (UE-specific Search Space, USS) or CSS.
[0191] In some embodiments, the unicast DCI may adopt a first format, which includes but is not limited to any of the following:
[0192] DCI format0_0; DCI format0_1; DCI format0_2; DCI format0_3;
[0193] DCI format1_0; DCI format1_1; DCI format1_2; DCI format1_3.
[0194] Among them, DCI format0_x is used to schedule the physical uplink control channel (Physical Uplink Shared Channel, PUSCH), and DCI format1_x is used to schedule the physical downlink control channel (Physical Downlink Shared Channel, PDSCH).
[0195] The present disclosure does not limit the first format of the unicast DCI that carries the sub-band resource indication information.
[0196] In some embodiments, the cyclic redundancy check (CRC) of the unicast DCI may be scrambled by a first RNTI, and the first RNTI may be a SBFD-specific RNTI.
[0197] In some embodiments, in response to detecting the unicast DCI in a first format in a USS or CSS according to the first RNTI, the terminal 101 determines that the first format is used to indicate the subband resource configuration in the time window.
[0198] In some embodiments, the unicast DCI in the first format is not used for scheduling data transmission, wherein the first format is the DCI format in which the CRC is scrambled by the first RNTI.
[0199] In some embodiments, the unicast DCI may include but is not limited to at least one of the following: subband indication information, the subband indication information is used to indicate whether the subband exists; time domain resource indication information of the subband, the time domain resource indication information is used to indicate the time domain resources occupied by the subband; frequency domain resource indication information of the subband, the time domain resource indication information is used to indicate the frequency domain resources occupied by the subband; time window indication information, the time window indication information is used to indicate the time window; and an index of the subband resource configuration.
[0200] The subband indication information may indicate whether a subband exists using 1 bit. For example, a bit value of "1" indicates the existence of a subband, and a bit value of "0" indicates the absence of a subband, and vice versa.
[0201] Alternatively, the subband indication information may be set to "true" or "false" to indicate whether a subband exists.
[0202] The present disclosure does not limit the indication method of the sub-band indication information.
[0203] The subband time domain resource indication information can be used to dynamically configure the time domain resources occupied by the subband for terminal 101. It is understandable that there can be one or more groups of time domain resources, and each group of time domain resources can be in units of slot, OFDM symbol, span, etc., which is not limited in this disclosure.
[0204] The frequency domain resource indication information of the subband can be used to dynamically configure the frequency domain resources occupied by the subband for terminal 101. It is understood that there can be one or more groups of frequency domain resources, and each group of frequency domain resources can be in the form of resource blocks (RBs) or resource block groups (RBGs), which is not limited in this disclosure.
[0205] The time window is the time domain range in which the subband resource configuration takes effect. Each time window may correspond to a group of time domain resources and / or a group of frequency domain resources.
[0206] The index of the subband resource configuration may be one of the indexes of the candidate subband resource configurations in the pre-configuration information. In this case, the unicast DCI may carry the index of the subband resource configuration, thereby saving DCI signaling resources.
[0207] Assuming that M sub-band candidate resource configurations are provided in the pre-configuration information, the index of the sub-band resource configuration carried in the DCI may occupy log2(M) bits. For example, if M=4, the index of the sub-band resource configuration carried in the DCI may occupy 2 bits.
[0208] Alternatively, the subband resource configuration index may be used to indicate a combination of one or more of the subband indication information, a set of time domain resources, a set of frequency domain resources, and a time window included in the first signaling. In some embodiments, when network device 102 sends pre-configuration information, information not included in the pre-configuration information may be carried in the first signaling, such as in a unicast DCI. This disclosure is not limited to this.
[0209] For example, network device 102 sends preconfigured information that includes index #1, corresponding to subband indication information #2, candidate time window #1, candidate time domain resource #1, and candidate frequency domain resource #2. Subband indication information #2 indicates the presence of a subband. Unicast DCI can carry index #0, corresponding to subband indication information #1, which indicates the absence of a subband.
[0210] In some embodiments, the first signaling may be a Medium Access Control Element (MAC CE).
[0211] In some embodiments, the MAC CE may include but is not limited to at least one of the following: subband indication information, the subband indication information is used to indicate whether the subband exists; time domain resource indication information of the subband, the time domain resource indication information is used to indicate the time domain resources occupied by the subband; frequency domain resource indication information of the subband, the time domain resource indication information is used to indicate the frequency domain resources occupied by the subband; time window indication information, the time window indication information is used to indicate the time window; and an index of the subband resource configuration.
[0212] The content of the above information included in the MAC CE is similar to the content of the above information included in the unicast DCI, and will not be repeated here.
[0213] In some embodiments, when the network device 102 sends pre-configuration information, information not included in the pre-configuration information may be carried in the first signaling, for example, carried in a MAC CE, which is not limited in the present disclosure.
[0214] In step S2103 , the terminal 101 sends hybrid automatic repeat request acknowledgment HARQ-ACK information of the unicast DCI to the network device 102 .
[0215] In some embodiments, the network device 102 may receive the Hybrid Automatic Repeat request-ACKnowledgement (HARQ-ACK) information.
[0216] In some embodiments, the network device 102 determines that the terminal successfully receives the unicast DCI based on the HARQ-ACK information, and / or the network device 102 can determine that the subband configuration indicated by the unicast DCI is effective based on the HARQ-ACK information.
[0217] In some embodiments, the terminal 101 may determine that the subband configuration indicated by the unicast DCI is effective upon receiving the unicast DCI.
[0218] In some embodiments, before the sub-band resource indication information takes effect, the terminal 101 may perform uplink and downlink transmission based on the TDD time slot configuration sent by the network device 102 .
[0219] Step S2104: The terminal 101 determines that the subband resource configuration indicated by the MAC CE is effective at the first time point.
[0220] In some embodiments, the first time point is 3 milliseconds after ACK information of the PDSCH carrying the MAC CE is sent.
[0221] In some embodiments, before the sub-band resource indication information takes effect, the terminal 101 may perform uplink and downlink transmission based on the TDD time slot configuration sent by the network device 102 .
[0222] Step S2105 : The network device 102 determines that the subband resource configuration indicated by the MAC CE is effective at a first time point.
[0223] In some embodiments, the first time point is 3 milliseconds after ACK information of the PDSCH carrying the MAC CE is sent.
[0224] In some embodiments, before the sub-band resource indication information takes effect, the network device 102 may perform uplink and downlink scheduling based on the TDD time slot configuration sent by the network device 102 .
[0225] In some embodiments, the names of information, etc. are not limited to the names described in the embodiments, and terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codeword", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.
[0226] In some embodiments, terms such as "send", "transmit", "report", "download", "transmit", "bidirectional transmission", "send and / or receive" can be used interchangeably.
[0227] In some embodiments, "obtain", "get", "get", "receive", "transmit", "bidirectional transmission", "send and / or receive" can be interchangeable, and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining by self-processing, autonomous implementation, etc.
[0228] In some embodiments, terms such as "certain", "preset", "preset", "setting", "indicated", "a certain", "any", and "first" can be interchangeable. "Specific A", "preset A", "preset A", "setting A", "indicated A", "a certain A", "any A", and "first A" can be interpreted as A pre-specified in a protocol, etc., or as A obtained through setting, configuration, or indication, etc., or as specific A, a certain A, any A, or first A, etc., but not limited to this.
[0229] In some embodiments, the method for determining resources involved in the embodiments of the present disclosure may include at least one of steps S2101 to S2105. For example, step S2101 may be implemented as an independent embodiment, step S2102 may be implemented as an independent embodiment, steps S2101+S2102 may be implemented as an independent embodiment, step S2103 may be implemented as an independent embodiment, steps S2101 to S2103 may be implemented as independent embodiments, step S2104 may be implemented as an independent embodiment, step S2105 may be implemented as an independent embodiment, step S2104+step S2105 may be implemented as an independent embodiment, and steps S2101+S2102+step S2104+step S2105 may be implemented as independent embodiments, but the present invention is not limited thereto.
[0230] In some embodiments, step S2101 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, if network device 102 no longer sends pre-configuration information via semi-static signaling, such as the second signaling, that is, network device 102 dynamically configures subband resources, step S2101 may not be performed.
[0231] In some embodiments, step S2102 is optional, and one or more of these steps may be omitted or replaced in different embodiments. For example, if the network device 102 sends the pre-configuration information via semi-static signaling, i.e., via the second signaling, and does not dynamically configure the subband resources, step S2102 may not be performed.
[0232] In some embodiments, steps S2103, S2104, and S2105 may be performed selectively. For example, when network device 102 sends a unicast DCI to terminal 101 that carries subband resource indication information, steps S2104 and S2105 may not be performed. For another example, when network device 102 sends a MAC CE to terminal 101 that carries subband resource indication information, step S2103 may not be performed.
[0233] In some embodiments, steps S2101 to S2105 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0301] After detecting the aforementioned DCI format of any format according to the SBFD-specific RNTI in the search space, the terminal determines that the DCI format is used to indicate the subband time-frequency domain resource configuration within the time window.
[0302] The DCI scrambled with the CRC by the SBFD-specific RNTI is not used for scheduling data transmission.
[0303] The SBFD-specific RNT scrambled DCI includes at least one of the following information:
[0304] subband indication information, where the subband indication information is used to indicate whether a subband exists;
[0305] sub-band time domain resource indication information;
[0306] Frequency domain resource indication information of the subband;
[0307] Time window indication information, which is the time domain range in which the subband resource configuration takes effect;
[0308] Index of the subband resource configuration.
[0309] Furthermore, the sub-band resource indication information in the DCI indicates one of the sub-band configuration information pre-configured by the network device.
[0310] The pre-configuration information is configured through RRC signaling or SIB1.
[0311] The pre-configuration information is at least one of the following information:
[0312] subband indication information, where the subband indication information is used to indicate whether a subband exists;
[0313] Candidate time domain resource indication information of the subband;
[0314] Candidate frequency domain resource indication information of the subband;
[0315] Candidate time window indication information, where the candidate time window is the time domain range in which the candidate subband resource configuration takes effect;
[0316] Index of the subband candidate resource configuration.
[0317] The network device does not carry the relevant information configured through RRC signaling or SIB1 in the DCI.
[0318] Furthermore, the terminal may feed back HARQ-ACK information of the DCI.
[0319] Method 2: The terminal receives a MAC CE carrying subband resource indication information sent by a network device, and determines the time-frequency resources of the subband within the time window through the subband resource indication information carried in the MAC CE.
[0320] The MAC CE includes at least one of the following information:
[0321] subband indication information, where the subband indication information is used to indicate whether a subband exists;
[0322] Subband time domain resource indication information;
[0323] Frequency domain resource indication information of the subband;
[0324] Time window indication information, which is the time domain range in which the subband resource configuration takes effect;
[0325] Index of the subband resource configuration.
[0326] The indication information in the MAC CE indicates one of the subband configuration information pre-configured by the base station.
[0327] The pre-configuration information is configured through RRC signaling or SIB1.
[0328] The pre-configuration information is at least one of the following information:
[0329] subband indication information, where the subband indication information is used to indicate whether a subband exists;
[0330] Candidate time domain resource indication information of the subband;
[0331] Candidate frequency domain resource indication information of the subband;
[0332] Candidate time window indication information, where the candidate time window is the time domain range in which the candidate subband resource configuration takes effect;
[0333] Index of the subband candidate resource configuration.
[0334] The validity time of the MAC CE is 3 milliseconds (ms) after the ACK of the PDSCH carrying the MAC CE is sent.
[0335] On the network device side:
[0336] The full-duplex network device sends UE-specific signaling carrying subband resource indication information to the full-duplex terminal, and indicates the time-frequency resources of the subband within the terminal time window through the subband resource indication information.
[0337] Method 1: A full-duplex network device sends a unicast DCI carrying a subband resource indication information field to a full-duplex terminal, and indicates the time-frequency resource occupancy of the subband in the terminal time window through the subband resource indication information carried therein.
[0338] The specific method is as on the terminal side, and will not be repeated here.
[0339] Method 2: The full-duplex network device sends a MAC CE carrying subband resource indication information to the full-duplex terminal, and indicates the time-frequency resources of the subband within the time window to the terminal through the subband resource indication information carried in the MAC CE.
[0340] The specific method is as on the terminal side and will not be repeated here.
[0341] In Example 1, it is assumed that the terminal is a Rel-18 or later version terminal with half-duplex capability or full-duplex capability, and this patent does not impose any restrictions. It is assumed that the network device side performs full-duplex operation on the semi-static downlink (DL) symbol of the time division duplexing (TDD) frequency band, or on the DL symbol indicated by the SFI, or on the semi-static flexible symbol, or on the flexible symbol indicated by the SFI, that is, scheduling downlink data and uplink data at the same time. It should be noted that the network device side can also perform full-duplex operation on the semi-static uplink (UL) symbol of the TDD frequency band, or on the UL symbol indicated by the SFI, that is, scheduling downlink data and uplink data at the same time.
[0342] The semi-static flexible symbol is determined by a time division duplex uplink and downlink common configuration (tdd-UL-DL-ConfigurationCommon) sent by a network device or by a tdd-UL-DL-ConfigurationCommon and a time division duplex uplink and downlink dedicated configuration (tdd-UL-DL-ConfigurationDedicated).
[0343] In this embodiment, it is assumed that the network device configures the time slot structure as DDDFU through TDD UL-DL configuration. That is, within the TDD configuration period, the first three slots are DL slots, the fourth slot is a flexible slot, and the fifth slot is a UL slot. Of course, this embodiment method can also be directly applied to other TDD UL DL time slot structures.
[0344] Taking into account the service load of network equipment, interference conditions, terminal service types and other requirements, the base station side dynamically adjusts the subband configuration in the SBFD slot through dynamic signaling.
[0345] In this embodiment, the network device indicates the subband resource location in the SBFD slot of the terminal through the following method:
[0346] The full-duplex terminal receives the unicast DCI carrying the subband resource indication information field, and determines the time-frequency resource occupancy of the subband in the time window through the subband resource indication information carried therein.
[0347] The unicast DCI includes but is not limited to DCI format 0_0 / 0_1 / 0_2 / 0_3 and DCI format 1_0 / 1_1 / 1_2 / 1_3.
[0348] The DCI is transmitted in the USS or CSS.
[0349] The CRC of the DCI is scrambled using the SBFD-specific RNTI.
[0350] After detecting any type of DCI format described above according to the SBFD-specific RNTI in the search space, the terminal determines that the DCI format is used to indicate subband time-frequency domain resource configuration within the time window.
[0351] The DCI scrambled with the CRC by the SBFD-specific RNTI is not used for scheduling data transmission.
[0352] The SBFD-specific RNT scrambled DCI format includes at least one of the following information:
[0353] subband indication information, where the subband indication information is used to indicate whether a subband exists;
[0354] sub-band time domain resource indication information;
[0355] Frequency domain resource indication information of the subband;
[0356] Time window indication information, which is the time domain range in which the subband resource configuration takes effect;
[0357] Index of the subband resource configuration.
[0358] Furthermore, the indication information in the DCI indicates one of the subband configuration information pre-configured by the base station.
[0359] The pre-configuration information is configured through RRC signaling or SIB1.
[0360] The pre-configuration information is at least one of the following information:
[0361] subband indication information, where the subband indication information is used to indicate whether a subband exists;
[0362] Candidate time domain resource indication information of the subband;
[0363] Candidate frequency domain resource indication information of the subband;
[0364] Candidate time window indication information, where the candidate time window is the time domain range in which the candidate subband resource configuration takes effect;
[0365] Index of the subband candidate resource configuration.
[0366] The network device does not carry relevant information configured through RRC signaling or SIB1 in the DCI.
[0367] Furthermore, the terminal may feed back HARQ-ACK information of the DCI.
[0368] In this embodiment, the aforementioned technical solution is illustrated using DCI format 1_1 scrambled with an SBFD-specific RNTI as an example. The CRC is transmitted in the USS using DCI format 1_1 scrambled with the SBFD-specific RNTI. The network device configures a corresponding search space for the DCI format. Of course, the SBFD-specific RNTI is determined via a protocol predefined method or configured via RRC signaling, and this embodiment does not impose any limitations thereon.
[0369] In this embodiment, it is assumed that the network device configures a UL subband candidate list through RRC signaling, for example, M possible UL subbands are configured, and the UL subband candidates have different time-frequency resource configurations. Then the UL subband indication information (indication) carried by the base station in the uplink authorization (UL grant) or downlink configuration (DL assignment) has a length of log2(M) bits. Taking M=4 as an example, the correspondence between the UL subband indication and the UL subband candidate is shown in Table 1. Of course, the list may include a configuration in which the subband is empty. If DCI format 1_1 indicates a configuration in which the subband configuration is empty, it means that there is no time-frequency resource configuration for the subband within the time window.
[0370] Table 1
[0371] Correspondingly, DCI format 1_1 needs to carry 2 bits of information for indicating the subband resource indication information on the target carrier. Of course, the DCI format 1_1 can carry subband resource indication information on multiple carriers, depending on the configuration of the network device, and this embodiment does not impose any limitation.
[0372] As another example, the DCI may carry at least any combination of the following information:
[0373] subband indication information, where the subband indication information is used to indicate whether a subband exists;
[0374] Subband time domain resource indication information;
[0375] Frequency domain resource indication information of the subband;
[0376] Time window indication information, which is the time domain range in which the subband resource configuration takes effect;
[0377] Index of the subband resource configuration.
[0378] In the aforementioned examples, subband-related information is preconfigured by the network device via RRC signaling. The subband resource indication information in the DCI only needs to indicate the effective preconfigured subband time-frequency domain information. For example, the network device preconfigures the UL subband candidates shown in Table 1. The bit value of the subband resource indication information in the DCI can be 00, corresponding to indicating UL subband configuration index #0.
[0379] The network device may also pre-configure some subband-related information through RRC signaling and place the remaining information in the DCI for indication. This patent does not impose any restrictions.
[0380] As another extreme example, the network device indicates the subband resource configuration information through the relevant information in the DCI without any RRC signaling pre-configuration.
[0381] As a more representative example, the base station notifies the full-duplex terminal of the subband resource configuration information within a certain time window through RRC signaling + DCI dynamic indication. The RRC signaling and DCI indication information respectively indicate at least one of the following information:
[0382] subband indication information, where the subband indication information is used to indicate whether a subband exists;
[0383] Subband time domain resource indication information;
[0384] Frequency domain resource indication information of the subband;
[0385] Time window indication information, which is the time domain range in which the subband resource configuration takes effect;
[0386] Index of the subband resource configuration.
[0387] In embodiment 2, as described in embodiment 1, the terminal feeds back the HARQ-ACK information of the unicast DCI carrying the subband time-frequency resource indication information. When feeding back the HARQ-ACK information of the DCI, the terminal puts the corresponding bit into a type-1, type-2, or type-3 CB for transmission.
[0388] After receiving the corresponding ACK information, the network device determines that the subband configuration is effective, and schedules the terminal on the SBFD slot according to the subband time-frequency resources.
[0389] If the network device does not receive the corresponding ACK information, it will choose whether to resend the subband time-frequency resource indication information according to actual needs. Before the subband time-frequency resource indication information takes effect, uplink and downlink scheduling is performed according to the TDD time slot configuration indicated by the network device.
[0390] In Example 3, it is assumed that the terminal is a Rel-18 or later version terminal with half-duplex capability or full-duplex capability, and this patent does not impose any restrictions. It is assumed that the network device side performs full-duplex operation on the semi-static downlink (DL) symbol of the time division duplexing (TDD) frequency band, or on the DL symbol indicated by the SFI, or on the semi-static flexible symbol, or on the flexible symbol indicated by the SFI, that is, scheduling downlink data and uplink data at the same time. It should be noted that the network device side can also perform full-duplex operation on the semi-static uplink (UL) symbol of the TDD frequency band, or on the UL symbol indicated by the SFI, that is, scheduling downlink data and uplink data at the same time.
[0391] The semi-static flexible symbol is determined by a time division duplex uplink and downlink common configuration (tdd-UL-DL-ConfigurationCommon) sent by a network device or by a tdd-UL-DL-ConfigurationCommon and a time division duplex uplink and downlink dedicated configuration (tdd-UL-DL-ConfigurationDedicated).
[0392] In this embodiment, it is assumed that the network device configures the time slot structure as DDDFU through TDD UL-DL configuration. That is, within the TDD configuration period, the first three slots are DL slots, the fourth slot is a flexible slot, and the fifth slot is a UL slot. Of course, this embodiment method can also be directly applied to other TDD UL DL time slot structures.
[0393] Taking into account the service load of network equipment, interference conditions, terminal service types and other requirements, the base station side dynamically adjusts the subband configuration in the SBFD slot through dynamic signaling.
[0394] In this embodiment, the network device indicates the subband resource location in the SBFD slot of the terminal through the following method:
[0395] The terminal receives a MAC CE carrying subband resource indication information sent by a network device, and determines the time-frequency resources of the subband within the time window through the subband resource indication information carried in the MAC CE.
[0396] The MAC CE contains at least one of the following information:
[0397] subband indication information, where the subband indication information is used to indicate whether a subband exists;
[0398] sub-band time domain resource indication information;
[0399] Frequency domain resource indication information of the subband;
[0400] Time window indication information, which is the time domain range in which the subband resource configuration takes effect;
[0401] Index of the subband resource configuration.
[0402] The subband resource indication information in the MAC CE indicates one of the pre-configured subband configuration information of the network device.
[0403] The pre-configuration information is configured through RRC signaling or SIB1.
[0404] The pre-configuration information is at least one of the following information:
[0405] The pre-configuration information is at least one of the following information:
[0406] subband indication information, where the subband indication information is used to indicate whether a subband exists;
[0407] Candidate time domain resource indication information of the subband;
[0408] Candidate frequency domain resource indication information of the subband;
[0409] Candidate time window indication information, where the candidate time window is the time domain range in which the candidate subband resource configuration takes effect;
[0410] Index of the subband candidate resource configuration.
[0411] The validity time of the MAC CE is 3 ms after the ACK of the PDSCH carrying the MAC CE is sent.
[0412] In this embodiment, the MAC CE is carried by the PDSCH.
[0413] In this embodiment, it is assumed that the network device configures the UL subband candidate list through RRC signaling, for example, M possible UL subbands are configured, and the UL subband candidates have different time-frequency resource configurations. Then the UL subband indication carried by the base station in the UL grant or DL assignment is log2(M) bits long. Taking M=4 as an example, the correspondence between the UL subband indication and the UL subband candidate is shown in Table 1. Of course, the list may include a configuration in which the subband is empty. If the MAC CE indicates a configuration in which the subband configuration is empty, it means that there is no time-frequency resource configuration for the subband within the time window.
[0414] Correspondingly, the MAC CE needs to carry 2 bits of information for indicating the subband indication information on the target carrier. Of course, the MAC CE can carry subband indication information on multiple carriers, depending on the configuration of the network device, and this embodiment does not impose any limitation.
[0415] As another example, the MAC CE may carry at least any combination of the following information:
[0416] subband indication information, where the subband indication information is used to indicate whether a subband exists;
[0417] Subband time domain resource indication information;
[0418] Frequency domain resource indication information of the subband;
[0419] Time window indication information, which is the time domain range in which the subband resource configuration takes effect;
[0420] Index of the subband resource configuration.
[0421] In the aforementioned examples, all subband-related information is pre-configured by the network device via RRC signaling. The indication information in the MAC CE only needs to indicate the effective pre-configured subband time-frequency domain information. The network device may also pre-configure some subband-related information via RRC signaling and indicate the remaining information in the MAC CE. This patent does not impose any restrictions.
[0422] As another extreme example, the network device indicates the subband time-frequency resource configuration information through the relevant information in the MAC CE without any RRC signaling configuration information.
[0423] As a more representative example, the base station notifies the full-duplex terminal of the subband time-frequency resource configuration information within a certain time window through RRC signaling + MAC dynamic indication. The RRC signaling and MAC CE indication information respectively indicate at least one of the following information:
[0424] subband indication information, where the subband indication information is used to indicate whether a subband exists;
[0425] Subband time domain resource indication information;
[0426] Frequency domain resource indication information of the subband;
[0427] Time window indication information, which is the time domain range in which the subband resource configuration takes effect;
[0428] Index of the subband resource configuration.
[0429] The validity time of the MAC CE is 3 ms after the ACK of the PDSCH carrying the MAC CE is sent.
