[0095] FIG2A is an interactive diagram of an information transmission method according to an embodiment of the present disclosure. As shown in FIG2A , the present disclosure embodiment relates to an information transmission method, which includes:

[0096] In step S2100 , the network device 102 configures a first subband for the terminal 101 .

[0097] In some embodiments, the first sub-band may be configured on a first time unit.

[0098] In some embodiments, the time unit in the embodiments of the present disclosure may be a time slot, an Orthogonal Frequency Division Multiplexing (OFDM) symbol, or a span, which is not limited in the present disclosure. A span includes multiple consecutive symbols.

[0099] In some embodiments, the first time unit may be defined as a Subband-Based Full Duplex (SBFD) time unit, and the SBFD time unit is shown in FIG. 2B , for example.

[0100] In some embodiments, the present disclosure does not limit the name of the first time unit.

[0101] In some embodiments, the transmission direction of the first time unit is flexible, and the network device configures a first subband in the first time unit with the flexible transmission direction. The first subband may be an uplink subband or a downlink subband.

[0102] Exemplarily, if the network device 102 configures an uplink subband for the terminal 101 in a first time unit with a flexible transmission direction, the terminal 101 may perform uplink transmission within the frequency domain range of the uplink subband of the first time unit.

[0103] Exemplarily, if the network device 102 configures a downlink subband for the terminal 101 in a first time unit with a flexible transmission direction, the terminal 101 may perform downlink transmission within the frequency domain range of the downlink subband of the first time unit.

[0104] In some embodiments, the transmission direction of the first time unit is opposite to the first sub-band. For example, the network device 102 configures an uplink sub-band for the terminal 101 in a downlink (DL) time unit.

[0105] Accordingly, the terminal 101 may perform uplink transmission within the uplink subband range of the downlink time unit, or the terminal 101 may perform downlink transmission within other frequency domain ranges of the downlink time unit.

[0106] In some embodiments, the transmission direction of the first time unit is opposite to the first sub-band. For example, the network device 102 configures a downlink sub-band for the terminal 101 in an uplink (UL) time unit.

[0107] Accordingly, the terminal 101 may perform downlink transmission within the downlink subband range of the uplink time unit, or the terminal 101 may perform uplink transmission within other frequency domain ranges of the downlink time unit.

[0108] In some embodiments, the network device 102 may indicate the time division duplexing uplink and downlink configuration (TDD UL DL configuration) currently used by the terminal in a semi-static or dynamic manner.

[0109] For example, the network device 102 may configure a semi-static TDD UL DL configuration via system messages, such as a System Information Block (SIB) and / or Radio Resource Control signaling (RRC signaling). The base station configures the cell-level time division multiplexing uplink and downlink configuration via higher layer signaling.

[0110] During the period configured by the base station, the base station configures the positions and quantities of downlink time units, flexible time units, and uplink time units.

[0111] Exemplarily, the network device 102 may dynamically indicate the uplink and downlink structures of one or more slots through a slot format indicator (SFI) carried by downlink control information (DCI) format 2_0.

[0112] Based on the current TDD UL-DL configuration, a certain amount of time is required to switch between DL and UL. This ensures that terminal 101 has sufficient lead time and switching time. This also ensures that network device 102 has sufficient time to perform the switch between receiving and transmitting. This switching time between UL and DL can be guaranteed by terminal 101 sending in advance.

[0113] However, whether using semi-static or dynamic configuration, TDD UL / DL configuration applies to the entire operating bandwidth. This means that when both uplink and downlink resources exist within a timeslot, such as an SBFD slot, the time domain range within which the terminal switches transmission direction must be specified.

[0114] For example, as shown in FIG2C , terminal 101 can perform downlink-to-uplink switching based on the scheduling of network device 102. When network device 102 schedules terminal 101 to perform transmission in different transmission directions on adjacent SBFD slots, terminal 101 requires a certain switching time, as shown in FIG2D , resulting in some symbols being unusable for data transmission.

[0115] Both terminal 101 and network device 102 need to clearly define the switching point, that is, the time domain range in which the terminal switches the transmission direction. Terminal 101 switches the transmission direction at this switching point, and network device 102 does not perform data scheduling at this switching point to avoid wasting network signaling resources.

[0116] Step S2101 : Terminal 101 sends capability information to network device 102 .

[0117] In some embodiments, network device 102 receives the capability information.

[0118] In some embodiments, the capability information is used to indicate a first transmission configuration supported by the terminal 101 .

[0119] Exemplarily, the first transmission configuration refers to a transmission configuration that can be supported when the terminal 101 communicates with the network device 102 on the first time unit or the first sub-band.

[0120] Exemplarily, the first transmission configuration is applied to the above-mentioned first time unit, and the first time unit may be an SBFD time unit.

[0121] Exemplarily, the first transmission configuration is applied to the first sub-band mentioned above, and the first sub-band may be an uplink sub-band or a downlink sub-band within the SBFD time unit.

[0122] In some embodiments, the capability information may be used to indicate a first configuration of the number of switching points within the time window.

[0123] Exemplarily, the time window may be a continuous time domain resource range.

[0124] Exemplarily, the time window includes the at least one first time unit mentioned above.

[0125] Exemplarily, since it takes a certain time for the terminal 101 to switch the transmission direction, the switching point may be a time domain range in which the terminal 101 switches the transmission direction.

[0126] Exemplarily, the switching point may also be referred to as an uplink / downlink switching point, which is a time domain range in which the terminal 101 switches from downlink to uplink or from uplink to downlink.

[0127] Exemplarily, the terminal 101 informs the network device 102 of a first configuration of the number of switching points supported by the terminal 101 within a time window through capability information.

[0128] In some embodiments, the capability information is used to indicate a first length of a supported time window.

[0129] Exemplarily, the time window includes at least one first time unit.

[0130] Exemplarily, the time window includes the existence range of the first subband in the time domain, as shown in FIG2E , where the first subband occupies slot#0 to slot2, and slot#0 to slot#2 in the time window are both first time units, i.e., SBFD time units.

[0131] Exemplarily, the time window includes multiple time units included in a time division multiplexing configuration period.

[0132] Exemplarily, the network device 102 configures the TDD UL-DL configuration to determine a time division multiplexing configuration period, which includes at least one first time unit. For example, as shown in FIG2F , the time window includes slot#0 to slot#4, where slot#1 to slot#3 are first time units.

[0133] Exemplarily, the time window includes a first number of time units that are continuous in the time domain, and the first number of time units includes at least one of the first time units.

[0134] For example, as shown in FIG. 2G , the time window includes slot # 0 to slot # 9 , wherein slot # 1 to slot # 3 , and slot # 6 to slot # 8 are the first time unit.

[0135] The first number and the start time unit of the time window may be determined by a protocol or configured by the network device 102, and this disclosure does not limit this. In some embodiments, the capability information is used to indicate the maximum number of switch points supported within the time window. In one example, the maximum number may be a non-negative integer.

[0136] Exemplarily, the terminal 101 does not expect to switch the transmission direction within the time window, and the maximum number of switching points supported within the time window indicated by the capability information is 0.

[0137] Exemplarily, the terminal 101 supports switching of the transmission direction within the time window, and the maximum number of switching points supported within the time window indicated by the capability information may be a positive integer, such as 1, 2, 3, ... . . .

[0138] Exemplarily, the network device 102 may configure the maximum number of candidate values ​​for the terminal 101 . For example, the candidate value set includes {0, 1, 2, ...}. The terminal 101 selects one of these candidate values ​​according to its own capability and sends it to the network device 102 .

[0139] Exemplarily, the maximum number of candidate values ​​may be agreed upon by a protocol, for example, the candidate value set includes {0, 1, 2 . . .}, and the terminal 101 selects one of these candidate values ​​and sends it to the network device 102 .

[0140] In an example, if the first subband satisfies the first condition or the first time unit satisfies the first condition, the maximum number of switching points supported within the time window indicated by the capability information may be 0.

[0141] Exemplarily, the first condition may be that the terminal 101 does not support transmission direction switching in the first subband or the first time unit, or the terminal 101 needs to perform a service in a specified transmission direction, or other conditions.

[0142] Exemplarily, the maximum number of switching points supported by the terminal 101 within the time window is 0, and the bit value indicated by the capability information may be "000".

[0143] Exemplarily, the maximum number of switching points supported by terminal 101 within the time window ranges from 0 to 5. When terminal 101 determines that the maximum number of switching points supported within the time window is 0, the bit value indicated by the capability information may be "110" or "111".

[0144] Exemplarily, the maximum number of switching points supported by terminal 101 within the time window ranges from 0 to 5. When the bit value of the capability information is "110" or "111", it can be used to indicate other information, such as the transmission direction, whether the existence of switching points within a first time unit is supported, etc.

[0145] In some embodiments, the capability information is used to indicate a supported number of time units associated with a switching point.

[0146] In an example, the switching point is a time domain range in which the terminal 101 switches the transmission direction.

[0147] In an example, the number of time units may include the minimum number of time units between two adjacent switching points.

[0148] The minimum number of time units between two adjacent switching points may be N OFDM symbols or M time slots, where N and M are both non-negative integers.

[0149] Exemplarily, the network device 102 may configure multiple candidate values ​​for the minimum number of time units between two adjacent switching points, and the terminal 101 selects one from the candidate values ​​according to its own capabilities and reports it to the network device 102 .

[0150] Exemplarily, a plurality of candidate values ​​for the minimum number of time units between two adjacent switching points may be agreed upon by the protocol, and the terminal 101 selects one from the candidate values ​​according to its own capabilities and reports it to the network device 102 .

[0151] In one example, the number of time units may include a minimum number of time units for continuous transmission in at least one transmission direction.

[0152] Exemplarily, the transmission direction includes but is not limited to uplink and downlink.

[0153] The minimum time unit number for uplink continuous transmission and the minimum time unit number for downlink continuous transmission may be equal to or different from each other, which is not limited in the present disclosure.

[0154] Exemplarily, the network device 102 may configure multiple candidate values ​​for the minimum number of time units for continuous transmission in at least one transmission direction, and the terminal 101 selects one from the candidate values ​​according to its own capabilities and reports it to the network device 102 .

[0155] Exemplarily, a plurality of candidate values ​​for the minimum number of time units for continuous transmission in at least one transmission direction may be agreed upon by the protocol, and the terminal 101 selects one from the candidate values ​​according to its own capabilities and reports it to the network device 102 .

[0156] In an example, the number of time units may include the minimum number of time units between two adjacent switching points and the minimum number of time units for continuous transmission in at least one transmission direction.

[0157] Exemplarily, the manner in which the capability information is used to indicate the number of time units may be similar to the manner in which the capability information is used to indicate the maximum number of switching points supported within the time window, and details thereof will not be repeated here.

[0158] In an example, the number of time units may also include other numbers, which is not limited in this disclosure.

[0159] In some embodiments, the capability information is used to indicate a time unit supporting the existence of a switching point within the time window.

[0160] In one example, the time window includes at least one of the first time units.

[0161] In one example, the switching point is a time domain range in which the terminal switches the transmission direction.

[0162] Exemplarily, the terminal 101 may indicate the time units supporting the existence of switching points within the time window in a bitmap manner.

[0163] For example, there are N time units within the time window, and the capability information occupies N bits, each of which is used to indicate whether a switching point exists for a time unit within the time window. Assuming that the bit value of the N bits is 1010, the terminal can determine that the first time unit and the third time unit support the existence of a switching point.

[0164] For another example, there are N time units in the time window, and the capability information occupies N / 2 bits, and each bit is used to indicate whether there is a switching point between two adjacent time units in the time window. Assuming that the bit value of N bits is 1010, the terminal can determine that the first time unit, the second time unit, the fifth time unit, and the sixth time unit support the existence of a switching point. The above is only an exemplary description, and the granularity of the capability information indication can be larger, and this disclosure does not limit this.

[0165] In some embodiments, the capability information is used to indicate the supported duration required to switch the transmission direction.

[0166] In an example, the time required to switch the transmission direction refers to the minimum number of time units required for the terminal to switch from uplink to downlink or from downlink to uplink.

[0167] The minimum number of time units may be a positive integer.

[0168] In some embodiments, the capability information is used to indicate whether the switching point is supported within one first time unit.

[0169] In an example, the terminal may indicate whether the switching point is supported within one first time unit through 1 bit.

[0170] Exemplarily, the bit value of the capability information is "1" to indicate support for the switching point within one first time unit.

[0171] Exemplarily, the bit value of the capability information is "0" to indicate that the switching point within one first time unit is not supported.

[0172] Vice versa is also true, which will not be elaborated here.

[0173] In some embodiments, the capability information is used to indicate two or more of the above items, which is not limited in this disclosure.

[0174] Exemplarily, when the capability information is used to indicate two or more of the above items, it can be indicated in sequence in a preset order. For example, from the most significant bit (MSB) to the least significant bit (LSB), it can sequentially indicate the first configuration of the number of switching points within the time window, the first length of the supported time window, the maximum number of switching points supported within the time window, the number of time units associated with the switching points supported, the time units supporting the existence of switching points within the time window, the time length required for the supported switching transmission direction, and whether the existence of switching points within one of the first time units is supported.

[0175] In some embodiments, the capability information is used to indicate other information related to the transmission configuration supported by the terminal, which is not limited in this disclosure.

[0176] In step S2102 , the network device 102 configures transmission configuration for the terminal 101 .

[0177] In some embodiments, the network device 102 may determine a first transmission configuration supported by the terminal 101 based on the capability information.

[0179] Exemplarily, if the maximum number of switching points supported by the terminal within the time window indicated by the capability information is 0, the network device 102 may determine that the first subband meets the first condition or the first time unit meets the first condition.

[0180] Exemplarily, the first condition may be that the terminal 101 does not support transmission direction switching in the first subband or the first time unit, or the terminal 101 needs to perform a service in a specified transmission direction, or other conditions.

[0181] In some embodiments, the network device 102 configures a second transmission configuration for the terminal based on the capability information.

[0182] In an example, the second transmission configuration information is lower than a first threshold, which is determined by the network device 102 based on the capability information.

[0183] Exemplarily, the capability information is used to indicate a first configuration of the number of switching points within the time window of the terminal 101. The first configuration may serve as a first threshold.

[0184] The network device 102 configures second configuration information for the terminal 101, including a second configuration of the number of switching points configured within the time window. The second configuration should be consistent with the first configuration, or lower than the first configuration.

[0185] Exemplarily, the capability information is used to indicate a first length of a time window supported by the terminal 101. The first length may serve as a first threshold.

[0186] The network device 102 configures second configuration information for the terminal 101, which includes a second length of the time window, and the second length should be less than or equal to the first length.

[0187] Exemplarily, the capability information is used to indicate the maximum number of switching points supported by the terminal 101 within the time window. The maximum number can be used as the first threshold.

The number of time units includes, but is not limited to, at least one of the following: the minimum number of time units between two adjacent switching points; and the minimum number of time units for continuous transmission in at least one transmission direction.

[0190] The network device 102 configures the terminal 101 with second configuration information, which includes the number of time units associated with the switching point, and the number may be greater than or equal to the minimum number of time units.

[0191] Exemplarily, the capability information is used to indicate that the terminal 101 supports time units with switching points within the time window.

[0192] The network device 102 configures second configuration information for the terminal 101, which includes a second time unit with a switching point. The second time unit may be a time unit that the terminal supports the existence of a switching point within the time window.

[0193] Exemplarily, the capability information is used to indicate the time required for switching the transmission direction supported by the terminal 101.

[0194] The network device 102 configures the terminal 101 with second configuration information, which includes a duration for the terminal to switch transmission direction. The duration may be greater than or equal to a duration required for switching transmission direction indicated by the capability information.

[0195] Exemplarily, the capability information is used to indicate that the terminal 101 supports the existence of a switching point within one of the first time units.

[0196] The network device 102 configures second configuration information for the terminal 101, where the second configuration information is used to indicate the existence of a switching point within a first time unit, as well as configuration information of the switching point.

[0197] Exemplarily, the capability information is used to indicate that the terminal 101 does not support the existence of a switching point within one of the first time units.

[0198] The network device 102 configures second configuration information for the terminal 101, and the second configuration information is used to indicate that there is no switching point within a first time unit.

[0199] In some embodiments, the network device 102 may configure a third transmission configuration for the terminal 101 .

[0200] The third transmission configuration does not depend on the capability information sent by the terminal 101.

[0201] The above description is merely an example, and all schemes in which the network device 102 configures transmission configuration for the terminal 101 should fall within the scope of protection of this disclosure.

[0202] Step S2103 , the network device 102 sends a transmission configuration to the terminal 101 .

[0203] In some embodiments, terminal 101 receives the transmission configuration.

[0204] In some embodiments, the network device 102 sends a second transmission configuration to the terminal 101 .

[0206] Step S2104 : The terminal 101 communicates with the network device 102 based on the second transmission configuration.

[0207] In some embodiments, the second transmission configuration is configured by the network device 102 based on capability information, and the terminal 101 can directly communicate with the network device 102 based on the second transmission configuration.

[0210] In some embodiments, the terminal 101 receives a third transmission configuration, wherein the number of switching points within the time window indicated by the third transmission configuration is greater than the maximum number of switching points supported within the time window indicated by the first transmission configuration.

[0211] In some embodiments, the first number is equal to the maximum number sent by the terminal via capability information.

[0212] In some embodiments, after the terminal switches the transmission direction a first number of times within the time window, the terminal does not expect to switch the transmission direction again within the time window. Exemplarily, the terminal does not expect to perform a transmission direction switch.

[0213] In some embodiments, the maximum number of switching points supported by the terminal within the time window is 0, and the terminal 101 does not expect to switch the transmission direction within the time window. That is, the terminal 101 only performs uplink transmission or downlink transmission within the time window, and the specific transmission direction depends on the instruction or configuration of the network device.

That is, terminal 101 only performs uplink transmission or downlink transmission within the time window, and network device 102 can configure or instruct terminal 101 on a specific transmission direction.

[0217] In some embodiments, the maximum number of switching points supported by terminal 101 within the time window is a positive integer, the number of times the terminal switches the transmission direction within the time window is equal to the number of switching points, and network device 102 will not schedule the terminal to switch the transmission direction again within the time window.

[0272] The above solution provided in the embodiment of the present disclosure is further illustrated below with examples.

[0273] Terminal side:

[0274] A full-duplex terminal, such as an SBFD-aware terminal, reports its capabilities regarding the number of uplink and downlink switching points it supports to the network. The terminal capabilities include at least one of the following:

[0275] 1. The length of the terminal reporting time window;

[0276] 2. The maximum number of uplink and downlink switching points supported by the terminal within the time window;

[0277] If the maximum number reported by the terminal is 0, it means that the terminal does not expect uplink or downlink switching to occur within the time window;

[0278] Wherein, the maximum number has multiple candidate values, which are integers greater than or equal to 0;

[0279] 3. The minimum distance between two adjacent uplink and downlink switching points supported by the terminal;

[0280] For example, N OFDM symbols or M slots;

[0281] 4. The time domain pattern of the switching points within the time window;

[0282] For example, the slot or symbol where the uplink and downlink switching points exist;

[0283] 5. The switching time length supported by the terminal;

[0284] The switching time includes C candidate values, where C is an integer greater than or equal to 1;

[0285] 6. Minimum duration of UL transmission or DL ​​reception;

[0286] Wherein, the time includes multiple candidate values;

[0287] 7. Whether the terminal supports uplink and downlink switching points in an SBFD slot.

[0288] Network device side:

[0289] The network device side receives the terminal capability reported by the terminal regarding the number of uplink and downlink switching points within the time window, and determines the scheduling strategy within the time window based on the relevant terminal capability to ensure that the number and position of the uplink and downlink switching points within the time window do not exceed the terminal capability.

[0290] 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 performs full-duplex operation in the downlink time slot of the time division duplexing (TDD) frequency band, that is, it schedules downlink data and uplink data at the same time. When performing full-duplex operation, the network device adopts one of the following methods, and this patent does not impose any restrictions:

[0291] The frequency domain resources used for DL ​​transmission and UL transmission within a DL slot are independent of each other and do not overlap, as shown in FIG5A ;

[0292] The frequency domain resources used for DL ​​transmission and UL transmission in the DL slot completely overlap, as shown in FIG5B ;

[0293] Frequency domain resources used for DL ​​transmission and UL transmission in a DL slot partially overlap, as shown in FIG5C .

[0294] In this embodiment, the network device notifies the terminal of the number of uplink and downlink switching points within a certain time range through indication signaling. The switching points are used for switching between downlink to uplink (DL-to-UL) and / or uplink to downlink (UL-to-DL). This patent does not impose any restrictions on the time required for uplink and downlink switching.

[0295] In this embodiment, the frame structure is assumed to be DDDSU, where D stands for downlink, S stands for flexible, and U stands for uplink. The network device configures uplink subbands (UL subbands) for uplink data transmission in the second, third, and fourth slots for the terminal. Based on service requirements, the network device can schedule or configure the terminal to transmit uplink or receive downlink data in the SBFD slots. Once the transmission direction changes, a certain switching time is required between uplink and downlink, as shown in Figure 2C.

[0296] In this embodiment, the terminal reports its capability regarding the number of uplink and downlink switching points to the network device. The capability reflects the number of uplink and downlink switching points that the terminal can support in consecutive SBFD slots.

[0297] In this embodiment, the terminal reports at least one or any combination of the following capabilities to the network device, which is not limited in this patent:

[0298] 1. The length of the terminal reporting time window;

[0299] The length of the reporting time window may have multiple candidate values, including but not limited to:

[0300] TDD cycle;

[0301] The timeframe for the UL subband to exist;

[0302] S OFDM symbols or slots;

[0303] 2. The maximum number of uplink and downlink switching points supported by the terminal within the time window;

[0304] If the maximum number reported by the terminal is 0, it means that the terminal does not expect uplink or downlink switching to occur within the time window;

[0305] Wherein, the maximum number has multiple candidate values, which are integers greater than or equal to 0;

[0306] 3. The minimum distance between two adjacent uplink and downlink switching points supported by the terminal;

[0307] For example, N OFDM symbols or M slots;

[0308] 4. The time domain pattern of the switching point within the time window;

[0309] For example, the slot or symbol where the uplink and downlink switching points exist;

[0310] 5. The switching time length supported by the terminal;

[0311] The switching time includes C candidate values, where C is an integer greater than or equal to 1;

[0312] 6. Minimum duration of UL transmission or DL ​​reception;

[0313] Wherein, the time includes multiple candidate values;

[0314] 7. Whether the terminal supports uplink and downlink switching points in an SBFD slot.

[0315] After receiving the terminal capability reported by the terminal, the network device schedules data on the continuous SBFD slots, or instructs the transmission of related reference signals, or configures a semi-static data channel according to the terminal capability.

[0316] For example, if the terminal reports that the number of uplink and downlink switching points supported within the time window is M, and the switching time is S, then when the base station configures or schedules related transmissions for the terminal, it should ensure that the number of switching points does not exceed M, and should ensure that the distance between DL and UL is greater than or equal to S.

[0317] In the second embodiment, as described in the first embodiment, it is assumed that the terminal reports the terminal capability regarding the number of uplink and downlink switching points to the network device.

[0318] If the scheduling or configuration of the network equipment causes the number of uplink and downlink switching points within the time window to exceed the terminal's capabilities, the terminal's behavior will be unpredictable. The specific operation method depends on the terminal side implementation and is not specified in the protocol.

[0319] In the above embodiment, the network device configures the number of switching points for the terminal based on the capability information reported by the terminal, thereby reducing the complexity of terminal control and improving the feasibility and availability of full-duplex communication.
